A roadbed maintenance and pavement crack sealing device

Abstract

This utility model relates to the field of highway maintenance equipment, and in particular to a roadbed maintenance pavement crack sealing device. It includes a base plate with a crack sealing mechanism on top and a position adjustment mechanism located on one side of the base plate. The position adjustment mechanism includes a first sliding plate slidably connected to one side of the base plate, with a first lead screw threadedly connected to its center. The distance between two adjusting rods located at the top of a telescopic tube is adjusted by moving two second sliding plates, thereby driving the connecting frame to move vertically downwards. This allows the telescopic tube to penetrate deep into the crack while maintaining its vertical position and preventing bending. When encountering wider cracks, the first sliding plate moves the telescopic tube within the crack, eliminating the need to move the sealing device along the front and back sides. This allows for adjustment of the telescopic tube's position according to the crack's width and depth, ensuring thorough crack filling and improving the quality of crack repair.

Description

Technical Field

[0001] This utility model relates to the field of highway maintenance equipment, and in particular to a highway subgrade maintenance pavement crack sealing device. Background Technology

[0002] According to the patent document with publication number CN222666507U, the patent document describes a method where a second motor drives a first gear to rotate, which in turn drives a first stirring rod to rotate. The rotation of the first gear drives two meshing second gears to rotate, which in turn drives the second stirring rod to rotate, thereby stirring the asphalt stored inside the storage tank. The asphalt is then pumped out by an asphalt pump and injected into the cracks in the road through a crack sealer. A roller at the rear, acting in response to a spring, flattens the asphalt protruding from the ground. The first motor drives a reciprocating screw to move a sliding block, which in turn moves the crack sealer laterally, thereby sealing the transverse cracks.

[0003] The patent document states that during the process of injecting asphalt into road cracks using a crack sealer, because the width and depth of the cracks vary but the distance between the crack sealer and the road surface is fixed, the asphalt cannot penetrate deep into the cracks, resulting in the cracks not being fully filled and completely sealed, thus affecting the quality of the crack sealer. Utility Model Content

[0004] The purpose of this utility model is to provide a roadbed maintenance and pavement crack sealing device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A roadbed maintenance pavement crack sealing device includes a base plate, a crack sealing mechanism on the top of the base plate, and a position adjustment mechanism located on one side of the base plate.

[0007] The position adjustment mechanism includes a first sliding plate, which is slidably connected to one side of the base plate. A first lead screw is threadedly connected to the middle of the first sliding plate. A telescopic tube is fixed to one side of the bottom of the first sliding plate. A connecting frame is fixed to the outer side of the bottom end of the telescopic tube. Two connecting plates are fixed to one side of the bottom of the first sliding plate. Several adjusting rods are evenly spaced on both sides of the telescopic tube. Two adjusting plates are cross-hinged between the two upper adjusting rods and the corresponding lower adjusting rods. Two second sliding plates for adjusting the distance between the several adjusting rods are slidably connected to the front of the base plate. A second lead screw is threadedly connected to the top of the two second sliding plates.

[0008] Preferably, the crack sealing mechanism includes a mixing cylinder, which is fixed to the top of the base plate. A mixing shaft is rotatably connected inside the mixing cylinder. An asphalt pump is provided on one side of the mixing cylinder, and a discharge pipe is fixedly connected to the output end of the asphalt pump.

[0009] Preferably, two scraper blades are fixed on the outside of the mixing shaft to scrape off the asphalt adhering to the inner wall of the mixing drum, and a first motor is fixedly installed at the input end of the mixing shaft.

[0010] Preferably, a push-pull rod is fixed on one side of the top of the base plate, and universal wheels are fixed at the four corners of the bottom of the base plate. A feed inlet is opened at the top of the mixing drum, the input end of the asphalt pump is fixedly connected to the bottom of the mixing drum, and a heating pipe is provided on the outside of the mixing drum.

[0012] Preferably, the top of the telescopic pipe is fixedly connected to the discharge pipe, two connecting plates are located on the front and rear sides of the telescopic pipe respectively, and several adjusting plates are located on the front and rear sides of the telescopic pipe respectively.

[0013] Preferably, two adjusting rods located at the top of the telescopic tube are slidably connected between two connecting plates, and two adjusting rods located at the bottom of the telescopic tube are slidably connected to the top of the connecting frame.

[0014] Preferably, the bottoms of the two second sliding plates are fixedly connected to the two adjusting rods located at the top of the telescopic tube.

[0015] The advantages compared to existing technologies are as follows: By adjusting the distance between the two adjusting rods located at the top of the telescopic tube through the movement of the two second sliding plates, the connecting frame is moved vertically downwards, thereby driving the telescopic tube into the depth of the crack while maintaining the vertical state of the telescopic tube and avoiding bending or deflection. When encountering a wider crack, the first sliding plate drives the telescopic tube to move within the crack, eliminating the need to move the filling device along the front and back sides. This allows for adjustment of the position of the telescopic tube according to the width and depth of the crack, ensuring that the crack is fully filled and improving the quality of crack repair.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8As shown, a roadbed maintenance pavement crack sealing device includes a base plate 1, a crack sealing mechanism 2 on the top of the base plate 1, and a position adjustment mechanism 3 located on one side of the base plate 1.

[0030] In this embodiment: the crack filling mechanism 2 includes a mixing cylinder 201, which is fixed to the top of the base plate 1. A stirring shaft 202 is rotatably connected inside the mixing cylinder 201. Two scraper blades 203 are fixed on the outside of the stirring shaft 202 to scrape off the asphalt adhering to the inner wall of the mixing cylinder 201. A first motor is fixedly installed at the input end of the stirring shaft 202. A feed inlet is opened at the top of the mixing cylinder 201. The input end of the asphalt pump 205 is fixedly connected to the bottom of the mixing cylinder 201. A heating pipe 204 is provided on the outside of the mixing cylinder 201. An asphalt pump 205 is provided at the bottom of the mixing cylinder 201. A discharge pipe 206 is fixedly connected to the output end of the asphalt pump 205. A feed inlet is opened at the top of the mixing cylinder 201. The input end of the asphalt pump 205 is fixedly connected to the bottom of the mixing drum 201. A heating pipe 204 is provided on the outside of the mixing drum 201. A push-pull rod is fixed on one side of the top of the base plate 1. Universal wheels are fixed at the four corners of the bottom of the base plate 1. The first motor drives the mixing shaft 202 to rotate, thereby mixing the asphalt in the mixing drum 201 evenly. The mixing shaft 202 drives the scraper 203 to rotate and scrape off the asphalt adhering to the inner wall of the mixing drum 201. The heating pipe 204 heats the mixing drum 201 to keep the asphalt inside the mixing drum 201 at the temperature required for filling the crack. The asphalt in the mixing drum 201 is pumped into the discharge pipe 206 by the asphalt pump 205.

[0031] In this embodiment: the position adjustment mechanism 3 includes a first sliding plate 301, which is slidably connected to one side of the base plate 1. A first lead screw 302 is threadedly connected to the middle of the first sliding plate 301. A telescopic tube 303 is fixed to one side of the bottom of the first sliding plate 301. The top end of the telescopic tube 303 is fixedly connected to the discharge tube 206. Two connecting plates 305 are respectively located on the front and rear sides of the telescopic tube 303. Several adjusting plates 306 are respectively located on the front and rear sides of the telescopic tube 303. A connecting frame 304 is fixed to the outer side of the bottom end of the telescopic tube 303. Two connecting plates 305 are fixed to one side of the bottom of the first sliding plate 301. The telescopic tube 303 is provided with equal distances on both sides. Several adjusting rods 307 are provided. The two upper adjusting rods 307 are hinged to the ends of their corresponding lower adjusting rods 307 with two adjusting plates 306. Two adjusting rods 307 at the top of the telescopic tube 303 are slidably connected between two connecting plates 305. Two adjusting rods 307 at the bottom of the telescopic tube 303 are slidably connected to the top of the connecting frame 304. Two second sliding plates 308 for adjusting the distance between the adjusting rods 307 are slidably connected to the front of the base plate 1. Second lead screws 309 are threaded to the top of the two second sliding plates 308. A first lead screw 302 is rotatably connected to one side of the base plate 1. A second lead screw 309 is fixedly installed at the input end of the first lead screw 302. The motor, the second sliding plate 308, and the second lead screw 309 are rotatably connected to the top of the base plate 1. A third motor is fixedly installed at the input end of the second lead screw 309. The bottoms of the two second sliding plates 308 are respectively fixedly connected to two adjusting rods 307 located at the top of the telescopic tube 303. The third motor drives the second lead screw 309 to move the two second sliding plates 308, thereby causing the two adjusting rods 307 located at the top of the telescopic tube 303 to slide closer together along both sides between the two connecting plates 305, thereby adjusting the distance between the two adjusting rods 307 located at the top of the telescopic tube 303. Through several adjusting rods 307 and hinged connections with several adjusting rods 307, the distance between the two adjusting rods 307 located at the top of the telescopic tube 303 is adjusted. The two adjusting rods 307 at the top increase the vertical spacing of the several adjusting rods 307, while decreasing the horizontal spacing of the several adjusting rods 307. The two adjusting rods 307 at the bottom of the telescopic tube 303 slide closer to each other on the top of the connecting frame 304, thereby driving the connecting frame 304 to move downwards in the vertical direction, thus driving the telescopic tube 303 into the depth of the crack, while maintaining the vertical state of the telescopic tube 303 and avoiding bending or deviating. When encountering a wider crack, the first lead screw 302 driven by the second motor drives the first sliding plate 301 to move along the front and rear sides, thereby driving the telescopic tube 303 to move within the crack, without needing to move the grouting device along the front and rear sides.

[0032] Working principle: Asphalt is added into the mixing drum 201 through the feed inlet. The heating pipe 204 heats the mixing drum 201 to maintain the asphalt inside the mixing drum 201 at the required temperature for filling the cracks. The first motor drives the mixing shaft 202 to rotate, thereby mixing the asphalt inside the mixing drum 201 evenly. During this process, the mixing shaft 202 drives the scraper 203 to rotate and scrape off the asphalt adhering to the inner wall of the mixing drum 201. The third motor drives the second lead screw 309 to move the two second sliding plates 308, thereby causing the two adjusting rods 307 located at the top of the telescopic tube 303 to slide closer together between the two connecting plates 305 along both sides, thereby adjusting the distance between the two adjusting rods 307 located at the top of the telescopic tube 303. Several adjusting rods 307 are hinged together with several adjusting rods 307. The adjusting rod 307 increases the vertical spacing of several adjusting rods 307, while decreasing the lateral spacing of several adjusting rods 307. The two adjusting rods 307 located at the bottom of the telescopic tube 303 slide closer to each other on the top of the connecting frame 304, thereby driving the connecting frame 304 to move downwards in the vertical direction, thus driving the telescopic tube 303 into the depth of the crack, while maintaining the vertical state of the telescopic tube 303 and avoiding bending or deflection. When encountering a wider crack, the second motor drives the first lead screw 302 to move the first sliding plate 301 along the front and rear sides, thereby driving the telescopic tube 303 to move inside the crack. There is no need to move the filling device along the front and rear sides. The push-pull rod drives the base plate 1 and the four universal wheels to move. The asphalt pump 205 pumps the asphalt in the mixing drum 201 to the discharge pipe 206 and the telescopic tube 303 to fill the crack.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
