Description

Technical Field

[0001] The utility model relates to the technical field of concrete road construction, in particular to a concrete road expansion joint filling device. Background Technique

[0002] A concrete road surface refers to a road surface with a cement concrete slab as the surface layer. It refers to a road surface structure composed of a cement concrete slab as the surface layer, with a base layer and a cushion layer provided below, also known as a rigid road surface. An expansion joint refers to an expansion joint provided on a cement concrete road slab, and its function is to enable the cement concrete slab to freely expand when the temperature rises.

[0003] At present, for the filling of expansion joints, construction workers need to first mix the required filling materials. Since there should be no hard objects or cement concrete slurry in the expansion joints, construction workers need to prepare the filling materials according to requirements. After preparation, the road surface gaps are filled through a filling device. Currently, it is mostly manual to mix the filling materials and then load them into the device. After loading, the expansion joints are filled by construction workers. In this way, the efficiency is relatively low and the workload of construction workers is increased. Therefore, we urgently need a concrete road expansion joint filling device to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a concrete road expansion joint filling device, which solves the problems raised in the background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A concrete road expansion joint filling device includes a base, a driving wheel is fixedly connected to the base, a bracket is fixedly connected to the upper surface of the base, a scraping component is arranged on the base, and a filling component is arranged on the bracket;

[0006] The scraping component includes a first hydraulic cylinder, the first hydraulic cylinder is fixedly connected to the base, the output end of the first hydraulic cylinder is fixedly connected to a first mounting frame, a first driving motor is fixedly connected to the first mounting frame, the output end of the first driving motor is fixedly connected to one end of a first transmission rod, and the other end of the first transmission rod is rotationally connected to a bearing in the first mounting frame, and a scraper is fixedly connected to the first transmission rod.

[0007] Through the above technical solutions, the scraper will move downward driven by the first hydraulic cylinder, and the first driving motor drives the scraper to move at an angle, so that the scraper forms an angle with the ground, and the first hydraulic cylinder will drive the scraper to stop moving after contacting the ground.

[0008] Preferably, the filling component includes a rectangular through hole, which is opened on the base and located inside the bracket. Hydraulic cylinders II are fixedly connected to both the left and right sides of the inner wall of the rectangular through hole. The output ends of the two hydraulic cylinders II are fixedly connected to clamping rods, and gaskets are fixedly connected inside the clamping rods.

[0009] Through the above technical solution, in this application, the hydraulic cylinder II acts to drive the clamping rod, and the clamping rod acts to clamp the sleeve, improving the stability during filling.

[0010] Preferably, a driving guide rail is fixedly connected to the bracket, and a driving block is slidably connected inside the driving guide rail. A sleeve is arranged inside the bracket. Clasps are fixedly connected to both the left and right sides of the sleeve. Connecting plates are fixedly connected to the opposite sides of the two driving blocks, and the clasps are clamped with the connecting plates. A discharge valve I is fixedly connected to the bottom end of the sleeve, and a conical pipe is fixedly communicated with the discharge valve I.

The slider moves along with the up and down movement of the driving block on the driving guide rail. When the driving block drives the sleeve to move up and down, the rectangular plate on the limiting bracket connected to the sleeve follows the movement through the slider. The rectangular plate and the limiting bracket act to limit the position of the sleeve.

[0012] Preferably, a cover is fixedly connected to the top end of the sleeve. A transmission rod II is arranged inside the sleeve, and a spiral blade is fixedly connected to the transmission rod II.

When the transmission rod II rotates, the spiral blade will drive the filling raw materials in the sleeve to be transported downward. That is, the driving motor II drives the transmission rod II to rotate forward. When it is not necessary to transport the filling raw materials downward, the driving motor II drives the transmission rod II to rotate reversely to transport the raw materials upward for a certain distance.

The spiral blade 518 on the second transmission rod 517 rotates clockwise to convey the raw materials in the sleeve 57 to the bottom end of the sleeve 57. While conveying, the operator moves the device to the position where the joint needs to be filled by means of the driving wheel 2 and the grip 7. Then, the sleeve 57 is moved downward through the driving block 56 on the driving guide rail 55. When the sleeve 57 passes through the rectangular through hole 51, the conical pipe 511 on the sleeve 57 moves to the expansion joint position.
