Description

Technical Field

[0001] The utility model belongs to the technical field related to road maintenance, in particular to a thermal shearing device for road crack sealant. Background Art

[0002] Cracks in highway pavement are one of the manifestations of road damage. Cracks not only affect the appearance of the road surface and reduce its smoothness, but also affect the service life of the entire road. In particular, when the road surface cracks, rainwater will seep through the cracks into the pavement base, subbase and even roadbed, which will corrode the concrete roadbed, weaken the strength of the base and soil subgrade, accelerate the destruction of the road, and shorten the service life of the road surface. Therefore, it is necessary to promptly and appropriately treat pavement cracks. During the delivery of caulking agent, due to its high viscosity, it will be in strips during delivery. Therefore, shearing equipment is needed to cut the caulking agent. However, in actual use, it still has the following disadvantages:

[0003] When the hot shearing equipment of the road crack sealant is working, it directly cuts. During the shearing process, since the road crack sealant is relatively viscous, the road shear is directly sheared by the shearing equipment. During the shearing process, it is easy to cause the viscous sealant to have a large amount of road crack sealant left at the shearing position, causing inconvenience in use;

[0004] When the hot shearing equipment of road crack sealant is working, if it is necessary to temporarily stop the delivery of road crack sealant, it is necessary to further seal it after shearing. During the sealing process, additional valves are required for control, and the equipment cost is relatively high. Utility Model Content

[0005] The purpose of the utility model is to provide a hot shearing device for road crack sealant. By arranging a connecting square tube, a conveying cavity, an insulation shell and a movable rod, the utility model solves the problem that the shearing device for road crack sealant easily causes a large amount of road crack sealant to remain at the shearing position during shearing, and temporarily stops the conveying of road crack sealant, which requires additional valve control equipment with high cost.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a hot shearing device for road crack sealant, comprising a transfer square tube, a conveying cavity, an insulation shell and a movable rod, wherein the front lower part of the transfer square tube is fixed with an insulation shell, the bottom of the insulation shell is fixed with a heating plate, the end of the insulation shell away from the transfer square tube is provided with a movable hole, the movable hole is movably connected with a movable rod, one end of the movable rod is arranged in the insulation shell, the end of the movable rod in the insulation shell is rotatably connected with a closing plate, when working, the crack sealant in the conveying cavity is guided to the output port through the transfer square tube, the crack sealant conveyed from the crack sealant conveying device is conveyed to the transfer square tube through the conveying cavity, the heating plate is fixed therein through the insulation shell, the closing plate is heated by the heating plate, and the closing plate heats and cuts the crack sealant in the transfer square tube.

[0008] Furthermore, a socket is provided at the lower front portion of the adapter square tube, the socket is connected to one end of the insulation shell close to the adapter square tube, and the closing plate is movably connected in the socket, and the adapter square tube is movably connected to the closing plate through the socket.

[0009] Furthermore, engaging strips are fixed on both sides of the inner wall of the adapter square tube above and below the socket, and the closing plate is slidably connected between the two engaging strips. The closing plate is movably connected to the closing plate through the engaging strips, and the adapter square tube is closed by the closing plate.

[0010] Furthermore, an output port is fixed at the bottom end of the adapter square tube, and a delivery hole is opened through the center of the top of the output port, and the adapter square tube outputs the sealant through the output port and the delivery hole.

[0011] Furthermore, a delivery port is provided through the center of the top of the delivery cavity, and four mounting holes are provided through the top of the delivery cavity outside the delivery port in a circular array. The delivery cavity delivers the crack sealant through the delivery port and is installed at the output end of the crack sealant delivery device through the mounting holes and mounting bolts.

[0012] Furthermore, an internal threaded barrel is fixed on the end face of the insulation shell outside the movable hole, a threaded column is fixed on the end of the movable rod away from the closing plate, a rotating rack is fixed on the end of the threaded column away from the movable rod, and the insulation shell is threadedly connected to the threaded column through the internal threaded barrel.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that a large amount of road crack sealant is easily retained at the shearing position when the shearing equipment of the road crack sealant is sheared by arranging a transfer square tube, a conveying cavity, a heat-insulating shell and a movable rod. The utility model heats the closing plate by energizing the heating plate in the heat-insulating shell to heat the closing plate. When the conveyed road crack sealant is sheared, the rotating frame is pushed, and the rotating frame drives the movable rod to move, pushing the closing plate to be inserted into the transfer square tube and enter between the two engaging strips to cut the road crack sealant. Therefore, when working, the position where the road crack sealant is cut off by the shearing equipment of the road crack sealant has a higher temperature and is less likely to cause sealant to remain.

[0015] The utility model solves the problem that the shearing equipment for road crack sealant temporarily stops the delivery of road crack sealant, which requires additional valve control equipment with high cost by arranging a transfer square tube, an insulation shell and a movable rod. The staff holds the rotating frame and pushes it, which drives the closing plate to move. The closing plate moves into the transfer square tube, so that the threaded column enters the internal threaded cylinder, and then the rotating frame is rotated to make the threaded column push the closing plate until the closing plate and the inner wall of the transfer square tube are tightly pressed, so that the lower part of the transfer square tube is closed, so that the shearing equipment for road crack sealant temporarily stops the delivery of road crack sealant during work without the need for additional valve control, and the equipment cost is low.

[0025] Among them Figure 1 、 2 As shown in Figures 5 and 6, a socket 101 is provided at the lower front portion of the adapter square tube 1. The socket 101 is connected to one end of the insulation shell 3 close to the adapter square tube 1, and the closing plate 403 is movably connected in the socket 101. The adapter square tube 1 is movably connected to the closing plate 403 through the socket 101, so that the closing plate 403 can move in and out of the adapter square tube 1 when it moves.

[0026] Among them Figure 1 、 2 As shown in Figure 5, engaging strips 102 are fixed on both sides of the inner wall of the adapter square tube 1 above and below the socket 101, and the closing plate 403 is slidably connected between the two engaging strips 102. After the closing plate 403 enters the socket 101, it is movably connected between the two corresponding engaging strips 102 in the adapter square tube 1, so that the lower part of the adapter square tube 1 is closed.

[0027] Among them Figure 1 、 2 As shown, an output port 103 is fixed at the bottom end of the adapter square tube 1, and a delivery hole 104 is opened through the center of the top of the output port 103. The output port 103 delivers the crack sealant into it through the delivery hole 104, and the crack sealant is output to a suitable position on the ground through the output port 103.
