[0046] The use method and working principle of the utility model foundation pit construction support are as follows:

[0047] When in use, first, the height adjustment component 1 is at the lowest point, and the worker stands on the standing platform 201. By electrically connecting the controller 10 with the infrared distance sensor 16, the controller 10 is set in advance for the required construction height. The controller 10 is electrically connected to the motor 14, and the start and shut down of the motor 14 are controlled by the controller 10. During the lifting process of the support platform 112, when the infrared distance sensor 16 measures the distance set by the controller 10, it transmits a signal to the controller 10, and the controller 10 controls the motor 14 to be turned off. In addition, by starting the motor 14, the output shaft of the motor 14 rotates, and at the same time drives the gear 5 to rotate. Under the corresponding meshing of the teeth of the gear 5 and the tooth groove 202, the tooth groove 202 will rotate, so that the worker standing on the standing platform 201 can rotate and adjust the construction direction according to the construction needs. In addition, through the protective function of the protective component 7, it is effectively prevented that the worker accidentally falls during construction. By sliding the rotating drum 120 in the slide groove 102, the rotating drum 120 is fixed on the fixed shaft 11 9, when the lateral angle between the first adjusting rod 110 and the second adjusting rod 108 is larger, the position of the support platform 112 is higher, and the first adjusting rod 110 and the second adjusting rod 108 are connected together by the connecting rod 114, and the block 109 can prevent the first adjusting rod 110 and the second adjusting rod 108 at both ends of the connecting rod 114 from falling off, and the roller 117 rolls in the hollow sliding hole 113, so that the support platform 112 can be lifted and lowered under the action of the second adjusting rod 108. In addition, the positioning plate 4 is fixed to the ground by the fixing screw 3, and the electric push rod 13 is started to make the electric push rod 13 extend and retract, and push and pull the second fixing plate 12 forward or backward, so that the angle between the first adjusting rod 110 and the second adjusting rod 108 is changed, and then the height of the support platform 112 is adjusted. When entering the standing platform 201, the worker enters by stepping on the outer pedal 8 and the inner pedal 9. By placing different types of construction tools in the first storage box 602 and the second storage box 604 respectively, it is convenient for workers to take tools during construction.
