Description
Technical Field
[0001] The utility model relates to the technical field of road and bridge construction tools, in particular to a scratch-proof column clamp. Background Art
[0002] At present, the clamps used in road and bridge construction are generally two-piece structures, that is, two opposing clamping blocks are used. When in use, the two are connected together by long bolts to form a closed clamp structure to clamp the column. During installation, the two clamping blocks will be pre-assembled first, and the long bolts will initially connect the two clamping blocks to form a whole that is sleeved outside the column. Then, a truck crane will be used to lift it to the preset elevation position and then tighten it. When disassembling, loosen the long bolts and slowly lower it with a hoist lifting equipment. However, during the installation and disassembly process, since it is difficult for the clamp to remain concentric with the column, scratches often occur, which damages the appearance of the column and also affects the construction progress.

[0019] A scratch-resistant column clamp according to an embodiment of the utility model is described below with reference to the accompanying drawings.
[0020] See also Figure 1 to Figure 2 According to an embodiment of the utility model, a scratch-proof column clamp comprises two oppositely arranged clamping blocks 1, the inner walls of the two clamping blocks 1 are arc-shaped, and the two clamping blocks 1 can be connected together by long bolts to form a closed clamp structure to clamp the column.
[0021] The inner walls of the two clamping blocks 1 are formed with a plurality of openings 2. The anti-scratch column clamping hoop also includes a plurality of movable wheel sets 3, and the wheels 4 of each movable wheel set 3 can partially extend into the area surrounded by the inner wall of the clamping block 1 through the corresponding opening 2, and retract out of the area surrounded by the inner wall of the clamping block 1, so as to prevent the inner wall of the clamping block 1 from contacting the outer wall of the column during the lifting process of the column clamping hoop and guide the movement of the column clamping hoop.
[0022] For example, during installation, the two clamping blocks 1 are pre-assembled, and the long bolts are used to initially connect the two clamping blocks 1 to form a whole that is sleeved outside the column. Then, the position of the wheel 4 of the movable wheel set 3 is adjusted so that it partially extends into the area surrounded by the inner wall of the clamping block 1 through the corresponding opening 2, and abuts against the outer peripheral wall of the column, so that the column clamp is concentric with the column, and then the column clamp is lifted to a preset elevation using a car crane, and the wheel 4 is retracted and tightened. During disassembly, the column clamp is lifted with a hoist, and the long bolts are loosened. Then, the position of the wheel 4 of the movable wheel set 3 is adjusted so that it partially extends into the area surrounded by the inner wall of the clamping block 1 through the corresponding opening 2, and abuts against the outer peripheral wall of the column, so that the column clamp is concentric with the column, and then the hoist is used to pull it slowly down.
[0023] When installing and removing the column clamp, the wheel 4 is used to prevent the inner wall of the clamping block 1 from contacting the outer wall of the column during the lifting and lowering process of the column clamp, and to guide the movement of the column clamp, which can effectively avoid scratches and thus avoid damage to the appearance of the column.
[0024] The movable wheel set 3 includes an adjustment seat 5, each of which is fixedly connected to the corresponding clamping block 1 at the corresponding opening. The adjustment seat 5 can be fixed to the opening by welding. The adjustment seat 5 forms a space for the wheel 4 to move, and two mounting grooves for accommodating and carrying the two ends of the rotating shaft of the wheel 4. The movable wheel set 3 also includes an adjustment member 6, which is used to drive the wheel 4 to partially extend into the area surrounded by the inner wall of the clamping block 1, and to keep the wheel 4 partially extended into the area surrounded by the inner wall of the clamping block 1.
[0025] Specifically, the adjustment seat 5 can be composed of two mounting plates 7, the two mounting plates 7 are arranged vertically and oppositely, and the wheel 4 is located between the two mounting plates 7. Both mounting plates 7 are formed with mounting grooves, and the two ends of the rotating shaft of the wheel 4 extend into the corresponding mounting grooves respectively, and can move along the extension direction of the mounting grooves. The mounting groove is arranged horizontally, and when the two ends of the rotating shaft of the wheel 4 are at one end of the mounting groove close to the inner wall of the clamping block 1, the wheel 4 partially extends into the area surrounded by the inner wall of the clamping block 1, and under the restriction of the adjustment member 6, the wheel 4 maintains a state of partially extending into the area surrounded by the inner wall of the clamping block 1. When the two ends of the rotating shaft of the wheel 4 are at one end of the mounting groove away from the inner wall of the clamping block 1, the wheel 4 retreats to the outside of the area surrounded by the inner wall of the clamping block 1.
[0026] In this embodiment, when each of the wheels 4 is in a state of partially extending into the area surrounded by the inner wall of the clamping block 1, the wheels 4 are distributed on two virtual circles at different positions. The two virtual circles have the same diameter and are respectively located on two parallel planes. For example, the number of the movable wheel groups 3 can be eight, and the number of the wheels 4 is also eight accordingly. When each of the wheels 4 is in a state of partially extending into the area surrounded by the inner wall of the clamping block 1, the eight wheels 4 are equally distributed on the upper and lower virtual circles, and the spacing between adjacent wheels 4 on the same virtual circle is the same or close.
[0027] The number of the adjusting members 6 is two, and the adjusting members 6 include a stud portion, and the mounting groove is formed with an internal thread that matches the external thread of the stud portion, and the stud portion can approach or move away from the inner wall of the clamping block 1 when rotating. For example, when the stud portion rotates clockwise, it approaches the inner wall of the clamping block 1, and when the stud portion rotates counterclockwise, it moves away from the inner wall of the clamping block 1. In the process of the stud portion approaching the inner wall of the clamping block 1, the adjusting member 6 can abut against the end of the rotating shaft of the wheel 4 to enable the wheel 4 to partially extend into the area surrounded by the inner wall of the clamping block 1 through the corresponding opening 2. After the wheel 4 is partially extended into the area surrounded by the inner wall of the clamping block 1, the bolt portion is stopped from rotating, and under the restriction of the adjusting member 6, the wheel 4 maintains a state of partially extending into the area surrounded by the inner wall of the clamping block 1. In practical applications, the adjusting member 6 can be a bolt.
[0028] The anti-scratch column clamp of this embodiment uses wheels to prevent the inner wall of the clamping block from contacting the outer wall of the column during the lifting and lowering process of the column clamp, and guides the movement of the column clamp, which can effectively avoid scratches and thus avoid damage to the appearance of the column.
