Embodiment 1

[0052] A kind of pipeline pothole take-off and landing equipment for road and bridge construction, such as figure 1 , figure 2 and Figure 4 As shown, it includes a support ring 1, a common frame 2, a take-up mechanism 3 and a fixing mechanism 4. The support ring 1 is provided with a common frame 2, and the right side of the common frame 2 is connected with a take-up mechanism 3, and the take-up mechanism 3 The lower part is provided with a fixing mechanism 4.

[0053] When the workman needs to enter the pipeline pothole to work, people first place the equipment, and people use the fixing mechanism 4 to fix the workman's ankles. , so that the parts of the take-up mechanism 3 are no longer clamped, and then people can turn the take-up mechanism 3 counterclockwise, so that the worker slowly falls into the depth of the pipeline pothole. When the worker falls into the pipeline pothole and needs to work When it is deep, people stop rotating the take-up mechanism 3, and people t...

Abstract

The invention relates to lifting equipment, in particular to pipeline pit lifting equipment for road and bridge construction. The technical problem to be solved is to provide the pipeline pit liftingequipment, which is characterized in that a worker can descend into a pipeline pit by rotating a rocking handle, and soil around the pipeline pit can be prevented from falling into the pit, for road and bridge construction. According to the technical scheme, the pipeline pit lifting equipment for road and bridge construction comprises a supporting ring, a common frame, a take-up mechanism and a fixing mechanism; the common frame is arranged on the supporting ring; one side of the common frame is connected with the take-up mechanism; and a fixing mechanism is arranged at the lower part of the take-up mechanism. According to the pipeline pit lifting equipment for road and bridge construction, when the worker works in the pipeline pit, the surrounding soil falls into the pit to disturb the work of the worker, and a soil retaining ring can effectively prevent the surrounding soil from falling onto a body of the worker.

Description

technical field [0001] The invention relates to a pothole take-off and landing device, in particular to a pipeline pothole take-off and landing device for road and bridge construction. Background technique [0002] At present, when workers enter the pipeline pit to work, other workers use ropes to tie the feet of the workers who enter the pipeline pit, and then enter the pipeline pit to work. Other workers need to hold the rope tightly to enter the pipeline pit The workers working in the hole are suspended and slowly move down to the position where they need to work. During this process, other workers need to keep pulling the rope. It is difficult to grasp the length of the rope when entering the pipeline pit, and the workers pulling the rope around the mouth of the pipeline pit will make the surrounding soil fall into the hole, disturbing the work of the workers in the hole. [0003] Therefore, it is necessary to develop a pipeline pothole lift-off and landing equipment fo...
