摘要:
In a toggle bar link (100) for conveyor pans of conveyors or guideway pans of extraction machine guideways, with toggle bar sockets (1) arranged at the sides of the pans in whose socket cut-outs (3) a toggle bar can be inserted and retained by securing elements (4), both the toggle bar (2) and the securing elements (4) as well as the toggle bar sockets (1) are constructed intrinsically symmetrically and the toggle bar sockets (1) are arranged symmetrical to a plane of symmetry (S) running through the joint between the pans. Owing to the symmetrical construction of the individual parts they can not only be produced simply but also no orientation problems are posed in the assembly of the individual parts.

A pan section for combined conveying and winning apparatuses having a bottom run and a top run for guiding driver elements of a conveyor chain, as well as a welded frame structure which has two side cheeks which consist of one-piece rolled profiles. The rolled profiles have a constant profile shape with a bottom leg and a top leg, which are angled outwards in the assembled state, and an intermediate leg being provided with an offset for supporting and welding at least one intermediate plate. The pan section further includes a substructure connected to the bottom leg of the rolled profiles to connect both bottom legs to one another at a distance from the intermediate bottom. The substructure also has mounting pieces positioned at the ends below the bottom legs for transverse-force transmission means.

A conveyor pan 10 for face conveyors in underground coal mining systems has outward race 1 and return race 2, between which a conveyor bottom 9 is formed, with toggle sockets 21, with guide means for a mining machine which can be moved along the wall, in particular a drum cutter-loader, and with a static loading ramp connected on the wall side to the conveyor pan, and extending from the floor to the level of the outward race, by means of which muck can be loaded into the outward race as the face conveyor is advanced. The loading ramp includes an angled guide plate 50, the lower section 51 of which is steeper relative to the conveyor bottom 9 or the floor 11 than the upper section 52.
摘要:
A rack arrangement for underground winning installations having bearing brackets being fastenable at pan sections of a face conveyor and which have two pin holes each, and having rack bars being detachably fastenable to the pin holes of adjacent bearing brackets via pin connections having connecting pins. In order to design the rack arrangement and the bearing bracket for easier fitting and to improve the interplay between bearing bracket and rack bars in operational use, both pin holes are designed as an elongated hole for accommodating the connecting pin 7.
摘要:
A conveyor pan for a mining conveyor having a substructure with two side elements and an intermediate floor as well as a changeable trough forming a top strand and being detachably and exchangeably fastenable to the substructure. The trough having side profiles, each with a top web, and the top strand fastening means including screw bolts being fixable in place on the substructure. In order to ease an exchange of the trough, at least the top web of one side profile is provided with a plurality of open-edged indentations, in which there are welded holding strips, which project laterally over the top web and are provided with a plurality of bolt holes for the passage of a plurality of screw bolts.

The present invention relates to a conveyor pan (110) for underground face or gate conveyors, with a pair of side parts (101) comprising cast parts which include cast vertical arms (113) extending over the height of the bottom run (106) and the top run (107), a lower cast flange arm (111) extending outwards to the rear, a cast foot flange (112) extending inwards onto whose lower side a base plate (104) is welded which closes the bottom run to the bottom, as well as on the end faces cast accepting elements (114) for the means of joining conveyor pans, and with a conveyor pan base (105) preferably comprising a rolled sheet. This has tongue like segments (109) on both long sides, which engage in cut-out slots (135) in the vertical arms (113) of the side parts (101) and are welded to them on the outer of the side parts (101).
摘要:
A toggle retainer (10) for toggle connections of conveyor pans (5) for chain scraper conveyors, guide troughs of mining machines and similar, with a locking plate (30) engaging across the locking extension (23, 24) on the toggle head (21, 22) of a toggle (20) and securing the toggle (20) in the toggle accepting pocket (9) against falling out to the side, both ends (31, 32) of which can be introduced into an insertion pocket (11, 12) in the toggle acceptor (1) and which for retention in the locking cut-outs (13, 14) of the toggle acceptor (1) have at least one aperture (37) into which the shaft (41) of a locking element (40) engaging in one of the locking cut-outs (13, 14) can be inserted. The locking plate (30) is provided with transverse borings (38, 39), one of which opens into the aperture (37) and in which a securing clamp (50) engagement can be inserted or is inserted retaining the shaft (41) by positive.

摘要:
A method for deep-frying foods in which the foods to be deep-fried are delivered to hot oil or fat and transported out of the hot oil after a predetermined residence time, wherein a steam zone with superheated steam is generated above a free surface of the oil, which shields the oil from the ambient air, and from which a flow of steam corresponding to an amount of water evaporating from the deep-fried foods is withdrawn.
摘要:
The device for climbing a pair of ropes (1) includes upper and lower clasps (4,6) for clamping each rope and connecting elements for holding a climber, which include a movable or solid seat (7, 12) or harness (23). Each clasp (4,6) has a housing (21); a yoke (3) in the housing (21) provided with an interior space having beveled inclines widening downward; cotters (10) positioned on opposite sides of the rope (1) in the interior space; rollers (11) arranged movably, but securably, between the cotters (10) and the beveled inclines; a compression spring (20) bearing on an upper end of the yoke (3); and a resilient time servo-component (9) arranged at a lower end of the yoke. The resilient time servo-component (9) acts on the yoke so that the clasp (4,6), when relieved, automatically clamps the rope after a predetermined time interval, thus protecting the climber.
