Description

Technical Field

[0001] The utility model relates to the technical field related to road and bridge construction, in particular to a cutting seam device for road and bridge construction. Background Technique

[0002] The seam cut on the concrete pavement is called a 'contraction joint'. During the process of concrete hardening and setting, after the concrete has hardened and set, the shrinkage caused by temperature drop will cause the concrete to crack, and the crack direction is relatively random, seriously affecting the pavement quality and service life. The shrinkage cracks of the concrete pavement are inevitable. Manual cutting of the contraction joint is to induce and control the position and direction of the shrinkage cracks of the concrete pavement to prevent random cracks from occurring.

[0003] During the cutting seam operation in the process of road and bridge construction, the steps are as follows: First, clean the cutting seam section, then draw the lines that need to be cut on the road surface, then open the cooling water valve of the cutting machine, the cooling water shoots towards the blade, lower the operation lifting handwheel uniformly to the required cutting seam depth, align the guide wheel with the drawn line, and perform the cutting seam;

[0004] As can be seen from the above content, for the cutting seam operation, a line drawing device and a cutting seam device are required. The existing line drawing device is not convenient to use, while the cutting seam device is equipped with rollers and guide wheels, which is very suitable for line drawing. If a line drawing device is added to it, it can directly push and draw the line, and the use is very convenient. Therefore, we want to improve the existing cutting machine to make it have a line drawing function. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Referring to Figures 1-4 , in the embodiments of the present utility model, a cutting slot device for road and bridge construction includes: a cutting slot machine body 1 and a line drawing assembly 2. The cutting slot machine body 1 is composed of a frame 11, a water tank 12, a saw blade 13 and a guide wheel 14. A protective cover 131 is installed outside the saw blade 13. A nozzle is arranged inside the protective cover 131 and communicated with the water tank 12. The guide wheel 14 is installed on a guide rod 141. The guide rod 141 is rotatably installed with the frame 11. A roller 111 is arranged at the bottom of the frame 11. A handrail 121 is arranged on the water tank 12.

[0021] During use, people can push the handrail 121 to move the cutting slot machine body 1 forward. In addition, a handwheel is installed on the frame 11 to adjust the height of the saw blade 13. When cutting slots are not required, the saw blade 13 can be lifted to leave the ground.

[0022] The line drawing assembly 2 is installed on the frame 11. The line drawing assembly 2 is composed of a mounting plate 21, a limiting rod 22, an adjusting rod 23, an adjusting block 24 and a line drawing cylinder 25. The mounting plate 21 is fixedly installed at the front end of the frame 11. The bottom of the limiting rod 22 is fixedly connected with the mounting plate 21. The top of the limiting rod 22 is fixedly installed with a top plate 221. The adjusting rod 23 is parallel to the limiting rod 22. The top of the adjusting rod 23 is rotatably installed with the top plate 221, and the bottom of the adjusting rod 23 is rotatably installed with the mounting plate 21. The adjusting rod 23 is a threaded rod, and the limiting rod 22 is a smooth rod. The adjusting block 24 is installed on the limiting rod 22 and the adjusting rod 23 and is simultaneously penetrated by the limiting rod 22 and the adjusting rod 23. The adjusting block 24 is slidably installed with the limiting rod 22 and is threadedly connected with the adjusting rod 23. The line drawing cylinder 25 is fixedly connected with the adjusting block 24.

[0023] A rotating handle 231 is installed at the top of the adjusting rod 23. By rotating the rotating handle 231, the adjusting rod 23 can be rotated. Since the adjusting rod 23 is a threaded rod and the adjusting block 24 is threadedly connected with the adjusting rod 23, when the adjusting rod 23 is rotated, the adjusting block 24 will move up and down along the limiting rod 22 and the adjusting rod 23, thereby achieving the effect of adjusting the height of the line drawing cylinder 25.

[0024] The lower part of the line-drawing cylinder 25 is funnel-shaped, and a ball 251 is fitted at the opening position of the bottom. The line-drawing cylinder 25 is filled with ink for line-drawing. By adjusting the height of the line-drawing cylinder 25, the ball 251 lands on the ground, pushing the body 1 of the slitting machine forward. When the ball 251 rolls, the ink on its surface will be carried to draw lines on the ground.

[0025] The lower part of the line-drawing cylinder 25 is funnel-shaped, and an opening is provided at the bottom, and a plug is provided at the opening. The line-drawing cylinder 25 is filled with powder for line-drawing. After removing the plug, the body 1 of the slitting machine is pushed forward, and the powder inside the line-drawing cylinder 25 falls to achieve the line-drawing effect.

[0026] The line-drawing cylinder 25 is made of transparent material, and a rotatable and openable flip cover 252 is installed at the top of the line-drawing cylinder 25, which is convenient for people to observe the remaining amount of ink or powder inside the line-drawing cylinder 25 so as to add it in time.

[0027] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0028] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
