Description

Technical Field

[0001] This utility model relates to the field of guardrail maintenance technology, and in particular to a bridge guardrail maintenance device. Background Technology

[0002] There are many structural types of bridge railings, with concrete railings being the most common. Concrete railings are made of materials such as cement, sand, gravel, water, and steel bars. Their stability and durability are directly related to traffic safety. Through proper maintenance, it can be ensured that concrete railings will not develop cracks or breakages during use, thereby extending their service life.

[0003] Issues to be aware of during maintenance include:

[0004] Curing time: The curing time should be long enough to ensure that the concrete reaches the design strength and durability requirements. Generally, the curing time should not be less than 7 days; for projects with special requirements, the curing time may be longer.

[0005] Temperature control: During the curing process, it is important to control the temperature difference between the inside and outside of the concrete to avoid cracking caused by excessive temperature difference. Generally, the temperature difference between the surface and internal temperature of the concrete should not exceed 20℃. 2 .

[0006] Humidity control: Maintain the balance between the internal humidity of the concrete and the ambient humidity to prevent deformation caused by shrinkage and expansion due to humidity changes.

[0007] Therefore, regularly spraying water on concrete guardrails is of great significance for preventing drying, improving strength, promoting normal hardening, and extending service life. Based on this, this utility model proposes a bridge guardrail maintenance device. Utility Model Content

[0027] like Figure 1-4 As shown, a bridge railing maintenance device includes a driver's cab 1. A vertical support frame 2 is installed at the front end of the driver's cab 1. A water tank placement frame 3 is installed at the bottom front of the vertical support frame 2, and a water tank 5 is installed inside the water tank placement frame 3. The outer arms of the vertical support frame 2 and the water tank placement frame 3 are connected by an inclined plate 4, which serves to strengthen the connection and provide support. In addition, to reduce the impact of the weight of the water tank 5 on the water tank placement frame 3 and improve the support strength of the water tank placement frame 3, several casters are symmetrically installed at the bottom of the water tank placement frame 3.

[0028] The vertical support frame 2 is equipped with a left-right adjustment mechanism 7 via an up-down adjustment mechanism.

[0029] The vertical adjustment mechanism includes a telescopic mechanism 9 installed at the bottom of the horizontal adjustment mechanism 7, with the fixed end of the telescopic mechanism 9 installed at the bottom of the vertical support frame 2. A sliding groove is provided on the inner side wall of the vertical support frame 2, and a slider that cooperates with the sliding groove is installed on the horizontal adjustment mechanism 7. The telescopic mechanism 9 can be a conventional telescopic mechanism such as a cylinder, hydraulic cylinder, or electric push rod.

[0030] A water pump 8 is mounted on the left-right adjustment mechanism 7, and a top plate 10 is mounted on the side wall of the mechanism 7. The left-right adjustment mechanism 7 includes a fixed cantilever 701, and a sliding cantilever 702 is slidably mounted on the outer side of the fixed cantilever 701. The fixed cantilever 701 and the sliding cantilever 702 are directly connected together by a cylinder 703. The telescopic end of the cylinder 703 is fixedly connected to the fixed cantilever 701, and the fixed end of the cylinder 703 is fixedly connected to the sliding cantilever 702. A water pump mounting seat 704 is mounted on the end face of the sliding cantilever 702 for mounting the water pump 8. Specifically, when the cylinder 703 is activated and begins to extend, the sliding cantilever 702 moves the water pump mounting seat 704 and the top plate 10 together along the horizontal direction of the fixed cantilever 701, thereby adjusting the left and right direction of the spray pipe and preventing incomplete water spraying.

[0031] A top support is installed at the bottom center of the top plate 10, and a top traveling wheel 15 is installed at the bottom of the top support. The top traveling wheel 15 is rolled on the top surface of the bridge railing 12. Clamping arms 13 are symmetrically installed on the left and right sides of the top support. Side traveling wheels 14 are installed on the inner sidewall of the other end of the clamping arms 13, and the side traveling wheels 14 are rolled on the sidewall of the bridge railing 12. The three traveling wheels 14 provide support and limit, ensuring the stable operation of the entire equipment on the bridge railing 12, thereby improving the efficiency and quality of water spraying and facilitating the maintenance of the railing.

[0032] The bottom of the top plate 10 is symmetrically equipped with traveling beams 18 on both the left and right sides. Matching rollers 17 are mounted on the traveling beams 18 and installed on the sprinkler pipe mounting brackets 16. The movement of the rollers 17 on the traveling beams 18 allows for adjustment of the position of the sprinkler pipe mounting brackets 16, thus fine-tuning the spraying to meet the needs of omnidirectional water spraying. The left and right sprinkler pipe mounting brackets 16 are connected together by connecting beams 19, forming a unified whole and improving stability and safety. Sprinkler pipes are installed on the sprinkler pipe mounting brackets 16, and several nozzles are installed on the sprinkler pipes, with the nozzle outlets facing the bridge railing 12. The water tank 5 is connected to the water pump 8 via an inlet pipe 6, and the water pump 8 is connected to the sprinkler pipes via an outlet pipe 11.

[0033] The sprinkler system consists of several vertically distributed side sprinkler pipes 21 and several horizontal top sprinkler pipes 20. The horizontal top sprinkler pipes 20 are located above the bridge railing 12, and the side sprinkler pipes 21 are located on both sides of the bridge railing 12. The bottom of the side sprinkler pipes 21 can be connected to an extension pipe via a pipe connector 22, which is useful when the bridge railing 12 is relatively high.

[0034] The operation process of this utility model is as follows:

[0035] First, based on the height of the bridge railing 12 and the water spraying position requirements, the top traveling wheel 15 and the side traveling wheel 14 are adjusted using the up-down adjustment mechanism and the left-right adjustment mechanism 7, so that they rest against the bridge railing 12. Then, depending on the height requirements, it is selected whether to connect the extension spray pipe through the pipe joint 22. Finally, the water pump 8 is started, and the water in the water tank 5 is pressurized by the water pump 8 through the water inlet pipe 6 and enters the spray pipe through the water outlet pipe 11, and is sprayed from the nozzle onto the surface of the bridge railing 12 to complete the water spraying maintenance operation.

[0036] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
