Technical Field
[0001] This utility model relates to the field of installation auxiliary tools, specifically an auxiliary tool for replacing walking boards. Background Technology
[0002] In some engineering construction fields, it is often necessary to install pedestrian walkways for people to walk on. Over time, these walkways inevitably become damaged and need to be replaced. However, current replacement methods typically involve prying up the damaged walkway, usually using a pry bar. Pry bars are inconvenient for cleaning the gaps at the pryed-up area, and the replacement also requires carrying an undamaged walkway and cleaning the removed walkway. To address these issues and facilitate the work of personnel, an auxiliary tool for replacing pedestrian walkways is proposed. Utility Model Content
[0003] The purpose of this utility model is to provide an auxiliary tool for replacing walking boards, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] An auxiliary tool for replacing a walking board includes a base, a mounting seat fixedly installed on the top of the base, a rotating seat rotatably connected inside the mounting seat, a connecting sleeve rotatably connected to the rotating seat via a slewing bearing, a drive arm disposed inside the connecting sleeve, a sliding part of the drive arm slidably connected to the inner wall of the connecting sleeve, a mounting arm fixedly connected to the bottom end of the drive arm, and a lifting fork fixedly installed at both ends of the bottom of the mounting arm.
[0006] As a further embodiment of this utility model: a sliding groove is provided in the base, and guide grooves are symmetrically provided on both sides of the sliding groove. A slider is slidably connected in the sliding groove, and a screw is rotatably connected in the sliding groove. The screw thread passes through the slider, and one end of the screw passes through the sliding groove. A handle is fixedly connected to the end of the screw outside the sliding groove. A connecting arm is slidably connected in the guide groove. The end of the connecting arm near the slider is fixedly connected to the side wall of the slider. A sleeve that matches the lifting fork is fixedly connected to the end of the connecting arm outside the base.
[0007] As a further improvement of this utility model: a spiral handle is fixedly installed at the top of the drive arm, and a rubber sleeve is fixedly fitted on the spiral handle.
[0008] As a further embodiment of this utility model: a base plate is fixedly connected to the bottom of both sides of the base, and a caster wheel is fixedly installed at the bottom of the base and the bottom of the base plate away from the base.
[0009] As a further improvement of this utility model, a limiting plate is fixedly connected to the top of the substrate.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. This utility model uses casters installed at the bottom of the base and substrate to easily move the device to the location of the walking board that needs to be replaced, so that the lifting fork is directly above the gap between the walking boards. The driving arm inserts the lifting fork into the gap between the walking boards. Since the connecting sleeve and the rotating seat are rotatably connected by a slewing bearing, the driving arm swings the lifting fork left and right to insert it deeper into the gap between the walking boards. The driving arm rotates the lifting fork upward to lift the walking board that needs to be replaced, thus removing the installed walking board. The operation is simple, and the leverage principle reduces the labor intensity of removing the walking board.
[0012] 2. This utility model uses casters installed on the base and the bottom of the substrate to facilitate the movement of the device. By placing the walking board to be replaced and the replaced walking board on the top of the substrate, it is convenient to carry the walking board and clean the replaced walking board.
[0013] 3. When not in use, this utility model allows the lifting fork 10 to be raised to its highest position via the drive arm 7. The screw 18 is rotated via the handle 14, and the rotating screw 18 drives the slider 15, which is guided by the slide groove 16, to slide. The slider 15, through the fixedly connected connecting arm 13, pushes the insert 12 to be directly below the lifting fork 10. The lifting fork 10 is then inserted into the insert 12 via the drive arm 7. The handle 14 is rotated in the opposite direction, so that the insert 12 fixes the lifting fork 10, thus realizing the storage of the lifting fork 10 and the fixed limitation of the drive arm 7. When not in use, this reduces the risk of the lifting fork injuring bystanders. Attached Figure Description
