[0028] In this embodiment, the spring 401 is fixedly connected to the caulking equipment body 1, and the anti-collision frame 402 forms a telescopic structure with the caulking equipment body 1 through the spring 401. When the caulking equipment body 1 is hit, the anti-collision frame 402 will generate pressure to squeeze the spring 401, and the pressure will be absorbed under the expansion and contraction and rebound of the spring 401, thereby improving a certain degree of cushioning and protecting the caulking equipment body 1. Example

[0029] On the basis of Example 1, a preferred embodiment of a cement concrete pavement expansion joint caulking device provided by the utility model is as follows: Figures 1 to 5As shown: the damper 404 is fixedly connected to the main body 1 of the caulking equipment, and the rubber block 403 and the anti-collision frame 402 form an integrated structure. The damper 404 prevents the spring 401 from continuously shaking, and the rubber block 403 absorbs the pressure generated during the collision.

[0030] In this embodiment, the sleeve 406 is fixedly connected to the caulking equipment body 1, and the anti-collision frame 402 forms a sliding structure with the sleeve 406 through the sliding rod 405. By colliding with the anti-collision frame 402, the sliding rod 405 is driven to slide inside the sleeve 406, thereby improving the stability of the anti-collision frame 402 when it is extended and retracted.

[0031] Furthermore, a moving wheel 2 is fixedly connected to the bottom of the caulking device body 1 , and the moving wheel 2 is symmetrically arranged with respect to the center line of the caulking device body 1 , so that the caulking device body 1 can be easily moved under the action of the moving wheel 2 .

[0032] Furthermore, a push handle 5 is fixedly connected to one side of the top of the caulking device body 1, and the push handle 5 and the caulking device body 1 form an integrated structure, and the caulking device body 1 is pushed by manually holding the push handle 5.

[0033] In addition, the bottom of the caulking equipment body 1 is movably connected with a support assembly 3, and the support assembly 3 includes a support frame 301, mounting screws 302, a mounting tube 303, an electric push rod 304, a support plate 305 and a rubber pad 306. The bottom of the caulking equipment body 1 is movably connected with the support frame 301, and the internal thread of the support frame 301 is connected with the mounting screws 302, and the support frame 301 forms a detachable structure with the caulking equipment body 1 through the mounting screws 302. The support frame 301 is placed on the bottom of the caulking equipment body 1, and then the mounting screws 302 are manually rotated to be threadedly connected to the inside of the caulking equipment body 1 to fix the support frame 301.

[0034] When in use, the outer wall of the support frame 301 is fixedly connected to the mounting tube 303, the interior of the mounting tube 303 is fixedly connected to the electric push rod 304, the bottom end of the electric push rod 304 is fixedly connected to the support plate 305, the bottom of the support plate 305 is fixedly connected to the rubber pad 306, and the support plate 305 forms a lifting structure with the support frame 301 through the electric push rod 304. Turning on the electric push rod 304 drives the support plate 305 and the rubber pad 306 to be lifted and lowered to the bottom and fit tightly with the ground, thereby improving the stability of the overall operation of the caulking equipment body 1.

[0035] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0036] The working principle is that when in use, first manually hold the push handle 5 to push the caulking equipment body 1, thereby driving the moving wheel 2 to rotate, and then driving the caulking equipment body 1 to move. When the movement is hit, it will collide with the anti-collision frame 402, thereby driving the sliding rod 405 to slide inside the sleeve 406, thereby improving the stability of the anti-collision frame 402 during extension and contraction. At the same time, the anti-collision frame 402 generates pressure to squeeze the spring 401, and the pressure is absorbed under the extension and rebound of the spring 401 to improve a certain buffering performance, thereby protecting the caulking equipment body 1. At the same time, under the action of the rubber block 403, it is easy to absorb part of the pressure generated during the collision, and the damper 404 is used to prevent the spring 401 from continuously shaking. When it moves to a suitable position, the electric push rod 304 is turned on to drive the support plate 305 and the rubber pad 306 to rise and fall to the bottom and fit closely with the ground, thereby improving the stability of the overall operation of the caulking equipment body 1 (the model of the electric push rod 304 is ZC01A).
