Description

Technical Field

[0001] The utility model relates to the technical field of clamping equipment, in particular to a clamping mechanism of an automatic bridge film covering device. Background Art

[0002] In bridge engineering, piers are an important basic link in bridge construction. The quality of bridge piers directly affects the safety and reliability of the entire bridge body, and the quality of bridge piers will also determine the service life of the bridge in the later stage.

[0003] Piers are mostly formed by pouring concrete. After the concrete is poured, it is necessary to isolate the moisture on the concrete surface from the atmosphere through film coating to reduce the evaporation of moisture, so that the moisture in the film can fully react with the cement in the concrete, and reduce the cracking of the concrete caused by insufficient moisture during the hydration process. Film coating curing is particularly important in hot, windy and dry air environments. The film coating can quickly seal the moisture of the concrete inside and form a long-term wet curing environment between the film and the surface of the commercial concrete. After final setting, there will be no temperature cracks on the concrete surface, and the concrete will be neat and beautiful. Film coating curing can reduce the number of manual watering curing, save labor, and maintain concrete in a timely manner. In extreme weather, the film coating can also prevent surface cracks and maintain ground heat.

[0004] At present, the film coating and maintenance of bridge piers on the market mainly rely on manual laying: manpower and tools are transported to the top of the pier by crane, and the curing film is put on the rope after the pulley is manually installed. The rope is controlled by manpower to rotate around the pier to coat the film. For safety reasons, automatic climbing devices are usually used to complete the automatic coating of bridge piers. During the operation, the automatic climbing device needs to clamp the bridge pier to ensure the stability of the climbing device so that the bridge pier can be coated. However, the conventional clamping method is basically completed by manually applying a force knob screw. In order to ensure the stability of the clamping position, the construction personnel need to exert great strength to apply the force knob, which is labor-intensive for the construction personnel and makes the efficiency very low. Utility Model Content

[0005] The utility model aims to provide a clamping mechanism for an automatic bridge film covering device, so as to solve the problem that the clamping work efficiency of the automatic climbing device using manpower is insufficient.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A further technical solution is that the clamping mechanism includes a clamping rod, one end of which extends out of the matching groove and is fixedly connected to a clamp, the bottom surface of the clamping rod is linearly matched with the turbine-shaped groove, and a driving mechanism is arranged on the shell, and the driving mechanism is transmission-connected to the turbine ring gear.

[0009] A further technical solution is that there are four clamping mechanisms.

[0010] A further technical solution is that the clamp is detachably connected to the clamping rod via screws.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Figures 1 to 7 This is an embodiment of the utility model.

[0024] Embodiment 1:

[0025] A clamping mechanism for an automatic bridge coating device comprises a shell 1, wherein the shell 1 comprises a left half clamping layer 101 and a right half clamping layer 102 fixedly connected by bolts and nuts, an annular mounting groove is provided on the inner wall of the shell 1, a left half turbine ring gear 201 and a right half turbine ring gear 202 are respectively provided in the mounting grooves of the left half clamping layer 101 and the right half clamping layer 102, the left half turbine ring gear 201 is connected with the right half turbine ring gear 202 by bolts and nuts to form a turbine ring gear 2, an annular groove 3 is provided on the bottom surface of the turbine ring gear 2, a plurality of fixing columns 4 are provided in the annular groove 3, the plurality of fixing columns 4 are fixedly connected to the shell 1, a turbine-shaped groove 8 is provided on the top surface of the turbine ring gear 2, a matching ring 9 is provided above the turbine ring gear 2, the outer wall of the matching ring 9 is fixedly connected to the shell 1, a plurality of matching grooves 10 are provided on the inner wall of the matching ring 9, and a clamping mechanism matching with the turbine-shaped groove 8 is provided in each of the plurality of matching grooves 10.

[0026] Example 2

[0027] On the basis of Example 1, the clamping mechanism includes a clamping rod 11, one end of the clamping rod 11 extends out of the matching groove 10 and is fixedly connected with a clamp 12, the bottom surface of the clamping rod 11 is linearly matched with the turbine-shaped groove 8, and a driving mechanism is provided on the housing 1, and the driving mechanism is transmission-connected with the turbine ring gear 2. By controlling the driving mechanism to apply force, the turbine ring gear 2 can be rotated, so that the position of the clamping mechanism can be controlled, wherein the clamp 12 is provided at the end of the clamping rod 11, so that the clamping mechanism can better clamp and fix the bridge body.

[0028] Example 3

[0029] Based on Example 2, there are 4 clamping mechanisms. By setting the number of clamping mechanisms to 4, no matter the cross section of the bridge body is circular or square, applying forces in multiple directions can ensure stable clamping of the bridge body.

[0030] Example 4

[0031] On the basis of Example 3, the clamp 12 is detachably connected to the clamp rod 11 by means of screws 13. The clamp 12 is mounted on the clamp rod 11 by means of screws 13, so that the clamp 12 can be easily replaced after being worn.

[0032] Example 5

[0033] On the basis of Example 4, the driving mechanism includes a driving motor 7, which is fixedly mounted on the outer wall of the housing 1, and a transmission screw 6 is fixedly connected to the output shaft of the driving motor 7, and a matching tooth 5 is provided at the bottom of the turbine ring gear 2, and the transmission screw 6 passes through the outer wall of the housing 1 and is gear-matched with the matching tooth 5. The driving motor 7 can accurately control the rotation direction of the turbine ring gear 2 through the transmission screw 6, which is more convenient and labor-saving than manual force control, and at the same time ensures the stability of the clamping bridge body.

[0034] Working principle: first split the entire clamping mechanism into two halves, and then reassemble it around the bridge body to its original state, power on the drive motor 7 to start, and the transmission screw 6 rotates to rotate the turbine ring gear 2. When the turbine ring gear 2 rotates, the clamping rod 11 will move laterally under the restriction of the turbine-shaped groove 8 and the matching groove 10, so that the clamp 12 on the clamping rod 11 can clamp the bridge body, ensuring that the clamping mechanism can be stably installed on the bridge body. When the clamping mechanism needs to move, control the drive motor 7 to reverse, so that the clamping rod 11 can be retracted into the matching groove 10, so that the clamp 12 relaxes the clamp on the bridge body.
