[0001] This utility model belongs to the field of maintenance equipment technology, specifically a protective railing spray maintenance device for road and bridge construction trolleys. Background Technology
[0002] In order to ensure the safety of vehicles and pedestrians, guardrails are usually installed on existing bridge decks and highway surfaces. In current projects, road and bridge construction trolleys are usually used for construction. At the same time, in order to facilitate the maintenance and spraying of guardrails, a guardrail spraying and maintenance equipment for road and bridge construction trolleys is needed.
[0003] The road and bridge construction trolley for guardrail spraying and maintenance equipment is a special equipment used for spraying and maintaining guardrails during the construction of bridges and roads. It usually includes a spraying system, a maintenance system, a walking system and a control system. By activating the walking system, the whole unit moves on the bridge surface, which in turn moves the spraying system and the maintenance system to position the guardrails and then sprays and maintains them.
[0004] Existing road and bridge construction trolley-based guardrail spraying and maintenance equipment is usually inconvenient to spray all steel guardrails that need maintenance at the same time, and manual water replenishment is required during spraying, which is inefficient. Therefore, in order to address the above problems, a road and bridge construction trolley-based guardrail spraying and maintenance equipment is proposed. Utility Model Content

[0012] The beneficial effects of this utility model are:
[0013] 1. This utility model, by setting up a spray assembly and connecting the water inlet pipe to an external hose, allows the float to rise when the water tank is relatively full. As the float rises, it drives the crossbar to rise, which in turn causes the long plate to slide against the inner wall of the water tank. When the water tank is relatively full, the groove on the long plate is not connected to the water inlet pipe, and no more water is added. When the water level drops, the groove connects to the water inlet pipe, and water flows into the water tank. The pump is then activated, and the pump delivers water to the spray box through the water delivery pipe, allowing the water to be sprayed out through the nozzles. This design enables water to enter the water tank, improving the working efficiency of the device.
[0014] 2. This utility model uses a No. 1 motor to drive the mounting shaft to rotate, which in turn drives the drive gear to rotate. The drive gear meshes with the driven gear, which in turn drives the two grinding discs to rotate, thereby polishing the surface of the guardrail. In addition, by setting up a spray box, the spray nozzles can spray the cured guardrail simultaneously, improving the working efficiency of the device. Attached Figure Description

A lifting component is provided on one side of the top of the platform 1. The maintenance component includes a mounting box 10. Multiple mounting shafts are arranged through the mounting box 10. A rotating disk 15 is provided at one end of each of the multiple mounting shafts.

The drive gear 13 meshes with the driven gear 14.
[0025] In operation, existing road and bridge construction trolley guardrail spraying maintenance equipment requires manual water replenishment during spraying, which is inefficient. Therefore, in this solution, the present invention sets up a spraying component, connecting the water inlet pipe 21 to an external hose. When the water tank 2 is relatively full, the float 23 floats at a higher position. As the float 23 rises, it drives the crossbar 24 to rise, and the crossbar 24 drives the long plate 25 to slide on the inner wall of the water tank 2. When the water is relatively full, the groove on the long plate 25 is not connected to the water inlet pipe 21, and no more water is injected. When the water level drops, the groove connects to the water inlet pipe 21, and water flows into the water tank 2. The pump 26 is then activated, and the pump 26 delivers water to the spray box 27 through the water delivery pipe, allowing the water to be sprayed out through the nozzle 28. This combination enables water to enter the water tank 2, improving the working efficiency of the device.
[0026] The spray assembly includes a spray box 27 located on the outer wall of the vertical plate 11. Multiple spray nozzles 28 are arranged on the outer wall of the vertical plate 11. A water tank 2 is located at the top of the vehicle platform 1. A vertical rod 22 is installed inside the water tank 2. A float 23 is slidably mounted on the vertical rod 22. A long plate 25 is slidably mounted on the inner wall of the water tank 2. A groove is penetrating the top of the long plate 25, and a crossbar 24 is penetrating the bottom of the long plate 25. The other end of the crossbar 24... One end is installed through the float 23. A water inlet pipe 21 is installed through the outer wall of the water tank 2. A pump 26 is installed at the top of the vehicle platform 1. The water inlet of the pump 26 is connected to the water tank 2 through a pipe. The water outlet of the pump 26 is connected to the spray box 27 through a water outlet pipe. Two support frames are symmetrically arranged on the bottom side of the vehicle platform 1. A rotating rod is arranged between the two support frames. A drive wheel is installed at one end of the rotating rod. A second motor 17 is installed on one side of the top of the vehicle platform 1. The output shaft of the second motor 17 is connected to the second rotating shaft via a coupling. A transmission wheel is provided at the top of the second rotating shaft, and a transmission belt 18 is fitted on the two transmission wheels. A wheel 19 is provided at the top of the rotating rod. The lifting assembly includes a first mounting ear 3. Two first mounting ears 3 are symmetrically arranged at the top of the car plate 1. A rotating rod is arranged through the two first mounting ears 3. A winding roller is provided on the rotating rod. A placement plate is provided on the outer wall of one of the first mounting ears 3. A third motor 31 is provided at the top of the placement plate. The output end of the third motor 31 is connected to the rotating rod via a coupling. A concave frame 32 is provided at the top of the car plate 1.

[0027] In operation, existing road and bridge construction trolley-based guardrail spraying and maintenance equipment is usually inconvenient to spray the steel guardrails that need maintenance simultaneously. However, in this solution, the device uses a No. 1 motor 12. Starting the No. 1 motor 12 drives the mounting shaft to rotate, which in turn drives the drive gear 13 to rotate. The drive gear 13 meshes with the driven gear 14, which in turn drives two grinding discs 16 to rotate, thereby polishing the surface of the guardrail. Furthermore, by setting up a spray box 27, the nozzles 28 can spray the maintained guardrails simultaneously, improving the working efficiency of the device.
[0028] Working Principle: Existing road and bridge construction trolley guardrail spraying maintenance equipment requires manual water replenishment during spraying, which is inefficient. Therefore, in this solution, the present invention sets up a spraying assembly, connecting the water inlet pipe 21 to an external hose. When the water tank 2 is relatively full, the float 23 floats at a higher position. As the float 23 rises, it drives the crossbar 24 to rise, and the crossbar 24 drives the long plate 25 to slide on the inner wall of the water tank 2. When the water is relatively full, the groove on the long plate 25 is not connected to the water inlet pipe 21, and no more water is injected. When the water level drops, the groove connects to the water inlet pipe 21, and water flows into the water tank 2. The pump 26 is then activated, and the pump 26 delivers water to the spray box 27 through the water delivery pipe, allowing the water to be sprayed out through the nozzles 28. This combination enables water to enter the water tank 2, improving the working efficiency of the device.
[0029] Existing road and bridge construction trolley-based guardrail spraying and maintenance equipment is typically inconvenient to spray the steel guardrails requiring maintenance simultaneously. However, in this solution, a primary motor 12 is installed. Starting the primary motor 12 drives the mounting shaft to rotate, which in turn drives the drive gear 13 to rotate. The drive gear 13 meshes with the driven gear 14, which in turn drives two grinding discs 16 to rotate, thereby polishing the surface of the guardrail. Furthermore, by installing a spray box 27 and spray nozzles 28, the maintained guardrails can be sprayed simultaneously, improving the working efficiency of the device.
