Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bridge technology, specifically relating to an attachment device for a cylindrical pier structure. Background Technology
[0002] During the construction of cylindrical piers, box-type safety ladder cages are used for working at height. To ensure safety, according to existing specifications, wall-mounted components for the box-type safety ladder cages must be installed every 4 meters in height. Existing technology, Chinese Patent Publication No. CN 216839024U, discloses a wall-mounted component for a box-type safety ladder cage for cylindrical piers, including a safety ladder cage of a certain height. Connectors are installed on the uprights of the safety ladder cage, and these connectors are connected to clamps via connecting rods. The clamps are locked and fixed to the cylindrical pier. The safety ladder cage is connected to the clamps by connecting rods, and the clamps are fixed to the cylindrical pier, thus achieving the connection between the safety ladder cage and the cylindrical pier. Its disadvantage is that the size of the clamp locking mechanism is fixed. Since the size of the cylindrical piers varies from bridge to bridge, when the size of the cylindrical pier is large or small, the previously used clamp locking mechanisms cannot be reused, resulting in high costs. Summary of the Invention
[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a cylindrical pier structure attachment device that can be used regardless of the size of the cylindrical pier, can be reused, and has low cost.
[0004] This utility model discloses an attachment device for a cylindrical pier structure, comprising a clamp, a ratchet, a support base, a drum, a handle, a connecting base, a connecting pipe, and a spring. The device is characterized in that: a clamp is placed on the support base and connected by an insertion pin; the drum is inserted into the support base; a ratchet is fixedly installed on the drum; the clamp engages with the ratchet; the clamp abuts against the spring; the spring is installed on the connecting base; a handle is fixedly installed on the clamp; the support base connects to the connecting base; and a connecting pipe is fixedly installed on the connecting base.
[0005] The chuck head can rotate on the support base.
[0006] The ratchet and drum can rotate on the support base.
[0007] The reel is equipped with a hook A.
[0008] Hook B is installed on the connector.
[0009] Compared with existing technologies, this utility model has significant advantages. As can be seen from the above technical solution: by placing a clamp head and inserting a pin on the support base, inserting a drum into the support base, fixing a ratchet on the drum, engaging the ratchet head with the clamp head, pressing against a spring, installing the spring on the connecting seat, fixing a handle on the clamp head, connecting the support base to the connecting seat, and fixing a connecting pipe on the connecting seat, the steel wire rope is wound around the cylindrical pier once, and then the two ends of the steel wire rope are hung on hooks A and B respectively. After inserting a rod into the drum and rotating the rod, the rod drives the drum to rotate, tightening the steel wire rope on the drum, fixing the connecting seat to the cylindrical pier, and connecting the steel pipe to the ladder column with a fastener. The connecting pipe is then connected to the steel pipe with a fastener. This allows for the use of cylindrical piers of varying sizes, reuse, and low cost. It is also applicable to all wall attachment measures for cylindrical structures, such as cable-stayed crane tower attachment and spiral pipe column attachment, and has wide applications.

[0017] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation methods, structure, features, and effects of this utility model.
[0018] The purpose of this utility model and the solution to its main technical problem are achieved by the following technical solution:
[0019] This utility model discloses a cylindrical support structure attachment device, comprising a clamp 1, a ratchet 2, a support base 3, a drum 4, a hook A5, a handle 6, a connecting base 7, a connecting pipe 8, a spring 9, and a hook B10. The device is characterized in that: the clamp 1 is placed on the support base 3 and connected by an insertion pin; the drum 4 is inserted into the support base 3; the ratchet 2 is fixedly installed on the drum 4; the clamp 1 engages with the ratchet 2; the clamp 1 abuts against the spring 9; the spring 9 is installed on the connecting base 7; the handle 6 is fixedly installed on the clamp 1; the support base 3 is connected to the connecting base 7; the connecting pipe 8 is fixedly installed on the connecting base 7; the clamp 1 can rotate on the support base 3; the ratchet 2 and the drum 4 can rotate on the support base 3; the hook A5 is installed on the drum 4; and the hook B10 is installed on the connecting base 7.
[0020] In use: Wrap the wire rope around the cylindrical pier once, then hang both ends of the wire rope on hooks A5 and B10 respectively. Place a rubber pad between the connecting seat 7 and the cylindrical pier. Insert the rod into the drum 4 and rotate the rod. The rod drives the drum 4 to rotate, and the drum 4 drives the ratchet 2 to rotate. The ratchet 2 rotates counterclockwise. When the ratchet 2 rotates, it pushes the locking head 1 away from the gear groove of the ratchet 2, and the spring 9 contracts. The wire rope is wound on the drum 4 and tightened to fix the connecting seat 7 to the cylindrical pier. Connect the steel pipe to the ladder column with a fastener. Connect the connecting pipe 8 to the steel pipe with a fastener. The steel pipe can then be connected to the box-type safety ladder cage. To disassemble, pull the handle 6. The handle 6 drives the locking head 1 to rotate and disengage from the gear groove of the ratchet 2. Rotate the drum 4 clockwise to loosen the wire rope. Remove the wire rope and the cylindrical pier structure attachment device.
[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
