Description

Technical Field

[0001] The utility model discloses engineering maintenance equipment, in particular to a protective wall maintenance vehicle. Background Art

[0002] During the road construction process, in some special sections such as roads, bridges, highways, etc., in order to prevent vehicles from rushing out from both sides of the road when they lose control, protective walls are often built on both sides of the road to prevent cars from rushing out. Currently, protective walls can be classified into metal protective walls and concrete protective walls according to their materials. Compared with metal protective walls, metal protective walls are easier to install, but their protective capabilities are weaker than concrete protective walls.

[0003] When constructing a concrete protective wall, it is often necessary to first build a formwork and pour concrete in the formwork. The formwork is removed 24 hours after the concrete pouring is completed. Since heat is generated during the solidification process of concrete, the concrete protective wall needs to be sprayed to cool it down after the formwork is removed to prevent the concrete from cracking.

[0004] Currently, concrete protective walls are often maintained by manual spraying for cooling, which is labor-intensive. Utility Model Content

[0005] The utility model aims to provide a protective wall maintenance vehicle, which is used to solve the problem that the existing spraying and cooling maintenance of the solidified concrete protective wall is often carried out manually, and the intensity of the manual labor is relatively high.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a protective wall maintenance vehicle, comprising:

[0007] Vehicle body;

[0008] A water tank is fixedly mounted in the vehicle body, and a pump connected to the interior of the water tank is mounted on the vehicle body;

[0009] A supporting wheel assembly is fixedly mounted on the bottom of the vehicle body and is used to be placed on the top end surface of the protective wall for moving the vehicle body;

[0010] The clamping wheel set is two in number and is respectively installed on the front and rear sides of the vehicle body, and includes a mounting rail and two sets of clamping legs. The mounting rail is fixedly installed on the bottom of the vehicle body. The two sets of clamping legs are slidably connected in the mounting rail through a driving block and driven by a driving member in the mounting rail to move in a mirror image. The close sides of the two sets of clamping legs are respectively installed with multiple sets of clamping rollers, and the bottom of the clamping legs is fixedly installed with a moving roller;

[0011] The spray assembly is installed on the rear side of the vehicle body, and includes a spray pipe and a lifting plate. The spray pipe is U-shaped, and multiple groups of sprayers are fixedly installed on the inner side of the spray pipe. The upper end of the spray pipe is connected to the pump through an infusion tube. The lifting plate is slidably installed on the vehicle body, and its bottom is fixedly connected to the spray pipe through a connecting rod, and is driven to rise and fall by the lifting parts on the vehicle body.

[0012] As a further solution of the utility model, the supporting wheel group includes a supporting frame and multiple groups of supporting wheels. The supporting frame is fixedly installed on the bottom of the vehicle body, and the multiple groups of supporting wheels are rotatably installed on the supporting frame and driven to rotate by a power motor.

[0013] As a further solution of the utility model, the driving member is a double-axis screw rod, which is rotatably mounted in the mounting guide rail, one end of which is transmission-connected to the first driving motor, and two groups of driving blocks are spirally connected to the two ends of the double-axis screw rod;

[0014] The double-axis screw rod rotates to drive the two sets of driving blocks to move in a mirror image.

[0015] As a further solution of the utility model, the clamping roller is slidably mounted on the clamping leg via a guide column, and the guide column is elastically connected to the clamping leg via a coil spring.

[0016] As a further solution of the utility model, the lifting member is an adjusting screw, which is vertically rotatably installed on the vehicle body and one end of which is transmission connected to the second drive motor. A transmission plate is provided on one side of the lifting plate, which abuts against the side of the vehicle body and has a mounting hole vertically opened thereon that is threadedly connected to the adjusting screw.

[0017] Compared with the prior art, the utility model designs a vehicle body, a water tank, a supporting wheel group, a clamping wheel group and a spraying assembly, wherein the vehicle body can be switched according to different spraying states and transfer states, and can be placed on the protective wall or removed from the protective wall accordingly. At the same time, when switched to the spraying state, the vehicle body is supported by the supporting wheel group at the bottom of the vehicle body and placed on the top end surface of the protective wall. Two sets of driving parts drive the corresponding clamping legs to clamp on both sides of the protective wall to support the vehicle body and prevent the vehicle body from tipping over, and drive the spray pipe to descend synchronously, and start the pump, so that the pump transports the water in the water tank to the spray pipe for spraying. At the same time, the power motor in the supporting wheel group is started to drive the vehicle body to move along the protective wall, thereby replacing the manual operation method and greatly reducing the labor intensity of personnel.

The upper end of the spray pipe 101 is connected to the pump 5 through the infusion pipe 11. The lifting plate 9 is slidably installed on the vehicle body 6, and its bottom is fixedly connected to the spray pipe 101 through the connecting rod 12, and is driven to rise and fall by the lifting member on the vehicle body 6;

[0024] When the utility model is in use, it can be switched according to the different spraying states and the transporting states. When switched to the spraying state, the vehicle body 6 is moved to the upper side of the protective wall 1, and is supported by the supporting wheel set 3 at the bottom of the vehicle body 6 and placed on the top end surface of the protective wall 1. At the same time, the two sets of driving parts drive the corresponding clamping legs 202 to clamp on both sides of the protective wall 1 to support the vehicle body 6 to prevent the vehicle body 6 from tipping over.
