The invention discloses a pipe gallery bracket with adaptive deformation. The pipe gallery bracket with adaptive deformation comprises a support; the support is hinged to lower ends of two struts; theupper ends of the two struts are hinged to two outer sliding sleeves respectively; the outer sliding sleeves are arranged on a pipeline in a sleeving manner and are connected with baffle plates through springs respectively; the baffle plates are fixed to the pipeline; and one baffle plate is fixed with a horizontal graduated scale respectively; the horizontal graduated scale is provided with twoalarm lamps and switches for the corresponding alarm lamps; the outer sliding sleeve, one the side of horizontal graduated scale, is fixed with a vertical pointer; the upper end of the vertical pointer is connected with the side surface of the horizontal graduated scale; and when an activity amount of the support exceeds a set value, the vertical pointer can touch the switches of the correspondingalarm lamps. By adopting the bracket, deformation can be automatically regulated according to deformation of a pipe gallery without lowering the supporting effect, horizontal and vertical change values can further be monitored according to a change value of a scale on the bracket, and alarm is timely sent when deformation exceeds a specified value. The bracket has the characteristics of simple structure, convenience in mounting, good stress state and low cost.
