摘要： Chain guide arrangement for a mining machine, in particular for an extraction plough. The chain guide arrangement comprises a first chain passage for a load strand and a second chain passage for a return strand of a drive chain of the mining machine. At the end areas of the chain passages there are provided a drive station and a return station for the drive chain. At least at one of the chain passages a chain guide for the load strand and/or for the return strand of the drive chain is provided in a transition area to the drive station/s and/or the return station. According to the invention, the chain guide comprises a retaining pocket being open towards the drive chain and at an end face thereof being bounded by a hinge pin arranged to be transverse to a direction of movement of the chain. The chain guide further comprises a hold-down device comprising a pin seating on at least its one end face which pin seating matches with the hinge pin and is open on one side, and a locking arrangement. The hold-down device comprises a pressure face adjoining against the drive chain when the hold-down device is in a state in which it is retained in the retaining pocket and locked.

摘要： A pick locking device for a plow pick that includes a pick shank inserted into a receptor box of a pick holder. The locking device may include a retaining pin and a deformable clamp element. The retaining pin may be forced through an opening on the pick holder into a locking groove extending in a shank insert direction along one side face of the shank. The clamp element may secure the retaining pin in a locked position, and may include a first leg and a second leg positioned at an angle to each other. The first leg may be inserted into a retainer in the pick shank and the second leg may be inserted into a locking recess on the retaining pin. The second leg may include a trunnion protruding from the first leg and an annular enclosed opening that extends to a rear of the first leg.

摘要： A bit holder for a ploughing bit, particularly a bottom bit of a coal plough, includes an insert pocket 12 which is open at the top side 11 for receiving and supporting a bit stem of the ploughing bit and which pocket 12 is bounded on its edges by two lateral supporting walls 20, 30, a front supporting wall 13 and a rear supporting wall 14 with the rear supporting wall 14 projecting above the front supporting wall 13. In order to minimise the wear effect on the contact surfaces between bit stem and bit holder, the lateral supporting wall 20 facing away from the working face when the plough is in use projects above the front supporting wall 13 and the other lateral supporting wall 30 and forms an extended lateral support for the bit stem with respect to the other supporting wall 30.

摘要： A coal plough for underground mining has a plough body that is guided along a plough guide. The plough body has at least one foot piece which receives a sliding skid. The sliding skid has at least one contact surface formed on its underside, which surface slides on a rail of the plough guide when the sliding skid is in its operating position. The sliding skid has first and second wear inlays on an underside which is arranged in the area of the highest load. The sliding skid can withstand high mechanical loads for a longer period of use.

摘要： The invention relates to a bit holder for a ploughing bit of a coal or extraction plough, with an insert pocket open on the top side for receiving a bit shank formed on the ploughing bit. The pocket is bounded by two lateral supporting walls, a front and a rear supporting wall, whereby the rear supporting wall has an elevated section projecting over the adjoining, lateral supporting walls. The rear supporting wall forming a bit support for the ploughing bit slopes down to its outer regions. In order to allow a good support for an inserted bit and easy and fast installation of the bit the front face of the rear supporting wall is fitted on the outer regions with guiding surfaces sloping down inwards to the insert pocket as an installation aid for the ploughing bit.
