Description

Technical Field

[0001] This utility model relates to the technical field of expansion joint maintenance devices, and in particular to a maintenance device for expansion joints of highway bridges. Background Technology

[0002] Expansion joint maintenance devices are used to maintain expansion joints in structures such as bridges and buildings. High-pressure cleaners are one of the main equipment for maintaining expansion joints, and they are used to wash and clean debris and dirt in the expansion joints.

[0003] Existing technologies, such as the utility model patent with publication number CN217104776U, disclose a cleaning device for expansion joint maintenance. This patent employs a mobile trolley, a breaking structure, a primary cleaning structure, a secondary cleaning structure, and a drive structure. The mobile trolley includes a mounting frame and wheels. The breaking structure is fixed to the front end of the mounting frame, and a first rotating shaft passes through the middle of the mounting frame. A wheel is connected to each end of the first rotating shaft, and the primary cleaning structure is fixed to the middle of the first rotating shaft. The primary cleaning structure is connected to the drive structure, and the drive structure is connected to the secondary cleaning structure, which is located behind the primary cleaning structure. This device links the primary and secondary cleaning structures, providing power for the cleaning operation by pushing the mobile trolley. It eliminates the need for electricity, solving the problem in existing technologies where poor cleaning results and residual material remain inside the expansion joint after cleaning with the brush, leading to insufficient cleaning to meet maintenance requirements.

[0004] The inventors discovered the following problems in their daily work when using high-pressure washers: when users hold the high-pressure nozzle to perform rinsing operations, the nozzle is far from the expansion joint, making it difficult to aim continuously, and water is easily sprayed outside the expansion joint, resulting in a large waste of water resources. Operating the high-pressure nozzle for a long time while bending over results in a heavy workload and low work efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the heavy workload of handheld high-pressure nozzles, the potential waste of water resources, and low work efficiency.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a highway bridge expansion joint maintenance device, comprising a vehicle body and a control lever. A water tank is installed on the upper surface of the vehicle body, and a pump body is installed on the upper surface of the vehicle body. A high-pressure water pipe is installed on the side of the water tank and the pump body that is close to each other. A high-pressure nozzle is installed at the output end of the high-pressure water pipe. An adjustment structure is provided on the surface of the control lever, the adjustment structure including two rollers rotatably connected to the control lever. A restraining strap is fixedly connected to the surface of the control lever, the restraining strap being slidably connected to the arc surface of the high-pressure water pipe. A fixing frame is fixedly connected to the surface of the control lever, and the inner wall of the fixing frame... A rotating shaft is rotatably connected, and a support plate is fixedly connected to the arc surface of the rotating shaft. A positioning rod is slidably connected to one side of the fixing frame, and a spring is sleeved on the arc surface of the positioning rod. The two ends of the spring are fixedly connected to the fixing frame and the positioning rod, respectively. Several positioning holes are opened on the surface of the support plate, and the inner wall of one of the positioning holes is slidably connected to the positioning rod. A mounting frame is fixedly connected to the end of the support plate away from the rotating shaft. A mounting plate is slidably connected to the inner wall of the mounting frame. The side of the mounting plate away from the mounting frame is fixedly connected to the high-pressure nozzle. A mounting rod is threaded into one side of the mounting frame, and the end of the mounting rod near the mounting frame is slidably connected to the mounting plate.

[0007] The aforementioned components achieve the following effects: by using the control lever to drive the high-pressure nozzle to perform maintenance work on the expansion joints, water waste can be reduced, work efficiency can be improved, and the workload can be reduced.

[0008] Preferably, the end of the positioning rod away from the fixed frame is rotatably connected to a pull ring.

[0009] The effect achieved by the above components is that the operating pull ring drives the positioning rod to move, making it convenient for the user to move the positioning rod.

[0010] Preferably, the end of the positioning rod near the fixing frame is arc-shaped.

[0011] The effect achieved by the above components is that the end of the positioning rod near the fixing frame is arc-shaped, which makes it easier for the positioning rod to slide into the positioning hole.

[0012] Preferably, a baffle is fixedly connected to the side of the mounting frame near the mounting rod, and the length of the baffle is less than the length of the mounting rod.

[0013] The effect achieved by the above components is to limit the movement of the mounting rod by using a baffle, so as to prevent the mounting rod from detaching from the mounting frame and being lost.

[0014] Preferably, the surface of the vehicle body is provided with an auxiliary structure, the auxiliary structure including an auxiliary frame, the auxiliary frame being fixedly connected to the vehicle body, an auxiliary frame being fixedly connected to the end of the auxiliary frame away from the vehicle body, an auxiliary rod being rotatably connected to the inner wall of the auxiliary frame, a clamping plate being threadedly connected to the arc surface of the auxiliary rod, the clamping plate being slidably connected to the inner wall of the auxiliary frame, and a clamping frame being fixedly connected to the side of the auxiliary frame near the clamping plate.

[0015] The effect achieved by the above components is that when the high-pressure nozzle is held in hand and the control lever is not used, the control lever is fixed to the vehicle body by the clamp and the frame, which makes it convenient for the user to manage the control lever as a whole and can prevent it from being lost.

[0016] Preferably, anti-slip pads are fixedly connected to the sides of the clamping plate and the clamping frame that are close to each other, and the anti-slip pads are rubber pads.

[0017] The effect achieved by the above components is to increase the friction between the clamping plate and the clamping frame surface through the anti-slip pad, so that the clamping plate and the clamping frame have a better limiting effect on the control lever.

[0018] Preferably, a plurality of anti-slip protrusions are fixedly connected to the end of the auxiliary rod away from the auxiliary frame, and the plurality of anti-slip protrusions are evenly distributed on the auxiliary rod.

[0019] The effect achieved by the above components is to increase the friction at the operating end of the auxiliary rod by using anti-slip protrusions, making it easier for the user to rotate the auxiliary rod.

[0031] The specific settings and functions of its adjustment structure 7 and auxiliary structure 8 will be discussed below.

[0032] Reference Figures 2 to 4As shown in this embodiment: the adjusting structure 7 includes two rollers 701, which are rotatably connected to the control lever 6. A restraint strap 702 is fixedly connected to the surface of the control lever 6, and the restraint strap 702 is slidably connected to the arc surface of the high-pressure water pipe 4. A fixing frame 703 is fixedly connected to the surface of the control lever 6, and a rotating shaft 704 is rotatably connected to the inner wall of the fixing frame 703. A support plate 705 is fixedly connected to the arc surface of the rotating shaft 704, and a positioning rod 70 is slidably connected to one side of the fixing frame 703. 6. A spring 707 is fitted onto the arc surface of the positioning rod 706. The two ends of the spring 707 are fixedly connected to the fixing frame 703 and the positioning rod 706, respectively. Several positioning holes 709 are formed on the surface of the support plate 705. The inner wall of one of the positioning holes 709 is slidably connected to the positioning rod 706. A mounting frame 710 is fixedly connected to the end of the support plate 705 away from the rotating shaft 704. A mounting plate 711 is slidably connected to the inner wall of the mounting frame 710. The mounting plate 711 is located away from the mounting frame 710. The mounting frame 710 is fixedly connected to the high-pressure nozzle 5. A mounting rod 712 is threaded into one side of the mounting frame 710. The end of the mounting rod 712 near the mounting frame 710 is slidably connected to the mounting plate 711. The high-pressure nozzle 5 is driven by the operating lever 6 to perform maintenance work on the expansion joint, which can reduce water waste, improve work efficiency, and reduce workload. The end of the positioning rod 706 away from the fixed frame 703 is rotatably connected to the pull ring 708. Operating the pull ring 708 drives the positioning rod 706 to move, which is convenient for the user to move the positioning rod 706. The end of the positioning rod 706 near the fixed frame 703 is arc-shaped, which makes it easy for the positioning rod 706 to slide into the positioning hole 709. A baffle 713 is fixedly connected to the side of the mounting frame 710 near the mounting rod 712. The length of the baffle 713 is less than the length of the mounting rod 712. The baffle 713 is used to limit the movement of the mounting rod 712 to prevent the mounting rod 712 from detaching from the mounting frame 710 and being lost.

[0033] Reference Figure 5As shown in this embodiment: the auxiliary structure 8 includes an auxiliary frame 81, which is fixedly connected to the vehicle body 1. An auxiliary frame 82 is fixedly connected to the end of the auxiliary frame 81 away from the vehicle body 1. An auxiliary rod 83 is rotatably connected to the inner wall of the auxiliary frame 82. A clamping plate 84 is threadedly connected to the arc surface of the auxiliary rod 83. The clamping plate 84 is slidably connected to the inner wall of the auxiliary frame 82. A clamping frame 85 is fixedly connected to the side of the auxiliary frame 82 near the clamping plate 84. When the high-pressure nozzle 5 is held in hand and the control lever 6 is not used, the control lever 6 is fixed to the vehicle body 1 using the clamping plate 84 and the clamping frame 85. To facilitate user management of the entire control lever 6 and prevent loss, anti-slip pads 86 are fixedly connected to the sides of the clamping plate 84 and the clamping frame 85 that are close to each other. The anti-slip pads 86 are rubber pads. The anti-slip pads 86 increase the friction between the surfaces of the clamping plate 84 and the clamping frame 85, making the clamping plate 84 and the clamping frame 85 have a better limiting effect on the control lever 6. Several anti-slip protrusions are fixedly connected to the end of the auxiliary rod 83 away from the auxiliary frame 82. The anti-slip protrusions are evenly distributed on the auxiliary rod 83. The anti-slip protrusions increase the friction at the operating end of the auxiliary rod 83, making it convenient for the user to rotate the auxiliary rod 83.

[0034] Detailed Instructions for Use: By setting the adjustment structure 7, first rotate the mounting rod 712. The mounting rod 712 moves away from the mounting frame 710 via the thread. When the mounting rod 712 is sufficiently away from the inner wall area of ​​the mounting frame 710, operate the high-pressure nozzle 5 to move the mounting plate 711 into the mounting frame 710. Then, rotate the mounting rod 712 in the opposite direction. The mounting rod 712 moves closer to the mounting frame 710 via the thread and moves into the mounting plate 711, fixing the mounting plate 711 inside the mounting frame 710. Then, start the pump body 3. Water in the water tank 2 is ejected through the pump body 3, high-pressure water pipe 4, and high-pressure nozzle 5. Move the control lever 6 along the expansion joint. During this process, the control lever 6 moves along the road surface or bridge surface via the roller 701, thereby driving the high-pressure nozzle 5 to perform flushing operations along the expansion joint. When it is necessary to adjust the angle of the high-pressure nozzle 5, first move the positioning rod 706 away from the fixed frame 703. The positioning rod 706 slides away from the support. The positioning hole 709 on plate 705 releases the restriction on support plate 705, and spring 707 is in a stretched state. Then, support plate 705 and rotating shaft 704 are rotated along fixed frame 703. During this process, support plate 705 drives high pressure nozzle 5 to rotate through mounting frame 710 and mounting plate 711. When it is rotated to a suitable angle, positioning rod 706 is released. Positioning rod 706 moves towards fixed frame 703 under the action of spring 707. Positioning rod 706 slides into positioning hole 709 at the corresponding position, fixing the angle of support plate 705 and high pressure nozzle 5. The operating pull ring 708 drives positioning rod 706 to move, making it easy for the user to move positioning rod 706. The end of positioning rod 706 near fixed frame 703 is arc-shaped, making it easy for positioning rod 706 to slide into positioning hole 709. Baffle 713 limits the movement of mounting rod 712 to prevent mounting rod 712 from detaching from mounting frame 710 and being lost.

[0035] By setting the auxiliary structure 8, the control lever 6 is first moved from the opening between the clamping plate 84 and the clamping frame 85 into the clamping frame 85. Then, the auxiliary rod 83 is rotated, and the auxiliary rod 83 drives the clamping plate 84 to move by means of the thread. The clamping plate 84 moves along the inner wall of the auxiliary frame 82 towards the clamping frame 85. The auxiliary rod 83 is rotated until the clamping plate 84 and the clamping frame 85 clamp and fix the control lever 6, thereby fixing the control lever 6 to the vehicle body 1. The anti-slip pad 86 increases the friction between the surfaces of the clamping plate 84 and the clamping frame 85, making the limiting effect of the clamping plate 84 and the clamping frame 85 on the control lever 6 better. The anti-slip protrusion increases the friction at the operating end of the auxiliary rod 83, making it easier for the user to rotate the auxiliary rod 83.
