[0001] This utility model relates to the field of maintenance and cleaning technology for highway bridge expansion joints, and in particular to a tool for cleaning bridge expansion joints. Background Technology

[0002] During road and bridge maintenance, it is necessary to clean the bridge expansion joints regularly to ensure smooth drainage. However, due to the narrowness of the expansion joints, large cleaning tools cannot be used, and traditional brooms and cleaning tools must be used for cleaning. Traditional manual cleaning is cumbersome, time-consuming, labor-intensive, inefficient, and has poor cleaning results. For road sections with a large proportion of bridges, the workload of workers is heavy, and the process of cleaning bridge expansion joints also requires long-term road occupation and frequent crossing of highways, which poses a high safety risk and brings great inconvenience and safety hazards to daily maintenance work.

[0003] Therefore, there is an urgent need to develop a tool for cleaning bridge expansion joints to overcome the shortcomings of existing technologies. Utility Model Content

[0011] Preferably, the cleaning shovel has V-shaped rolled edges on both sides, and the V-shaped rolled edges match the bridge expansion joints.

[0012] This utility model discloses a tool for cleaning bridge expansion joints, which has the following beneficial effects.

[0013] This utility model includes a front-opening collection box, a hinged operating lever, a cleaning shovel, rubber directional wheels, and steel-shafted pulleys. The bottom front of the collection box has a V-shaped opening, and the cleaning shovel has V-shaped rolled edges on both sides. Working in conjunction with the rubber directional wheels, it can accurately embed itself into the expansion joint and limit its movement, preventing damage to the rubber waterstop during cleaning. The hinged operating lever consists of a hinged base and a telescopic rod. The telescopic rod abuts against the top of the collection box through a limiting bevel. Pressing the operating lever causes the tool to tilt upwards around the steel pulley, gathering debris to the rear of the collection box. Lifting the operating lever causes the front of the collection box to rotate downwards around the hinged base, achieving rapid emptying.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1

[0024] Reference Figures 1 to 3 , Figure 7 A bridge expansion joint cleaning tool includes: a collection box 2, a hinged operating lever 1 located at the top of the collection box 2, and a rubber directional wheel 4 located at the center of the bottom of the collection box 2. The rubber directional wheel 4 can be embedded in the expansion joint and roll. A control device is used to adjust the distance between the cleaning shovel 3 and the rubber waterstop to prevent damage to the rubber waterstop during the cleaning process. Please refer to [reference needed]. Figure 6 The collection box 2 is a rectangular box with an open front end. A steel-shaped shaft pulley 201 is rotatably connected to the rear end of the collection box 2. A V-shaped opening is provided at the bottom of the front end of the collection box 2, and a cleaning shovel 3 is provided at the bottom of the V-shaped opening. In this embodiment, the steel-shaped shaft pulley 201 is rotatably connected to the collection box 2 through a connecting hole at the rear end of the collection box 2. Preferably, an angle steel can be used to separate the steel-shaped shaft pulley 201 from the debris in the collection box 2. The steel-shaped shaft pulley 201 facilitates pushing on the road surface, reduces pushing resistance during tool use, and reduces wear on the collection box 2. Example 2

[0025] Based on Example 1, please refer to Figure 1 , Figure 2 and Figure 5 Preferably, in this embodiment, the hinged operating lever 1 includes: a hinge seat 103 located at the rear center of the top of the collection box 2, and a telescopic rod 101 rotatably connected to the hinge seat 103 at its bottom.

[0026] Preferably, in this embodiment, the hinge seat 103 is rotatably connected to the telescopic rod 101 by the connecting bolt 102.

[0027] Please refer to Figure 5 Preferably, in this embodiment, the bottom of the telescopic rod 101 is provided with a limiting bevel, which abuts against the top of the collection box 2. It should be noted that... Figure 1 As shown, when the limiting bevel is fully abutted against the top of the collection box 2, press down on the telescopic rod 101. The bridge expansion joint cleaning tool will rotate around the steel shaft pulley 201 as the axis, causing the collection box 2 and the cleaning shovel 3 to tilt upwards, so that the collected debris gathers at the rear end of the collection box 2. Example 3

[0028] Based on embodiments 1 and 2, as a preferred embodiment, in this embodiment, the telescopic rod 101 includes: a lower sleeve, an upper sleeve fitted inside the lower sleeve, and a limiting bolt; the lower sleeve has a limiting hole on its outer wall, and the upper sleeve has a plurality of positioning holes with a diameter equivalent to the limiting hole on its outer wall, the plurality of positioning holes being arranged at equal intervals, and the limiting bolt being fitted inside the limiting hole and the positioning hole; the upper sleeve has a handle at its top.

[0029] Please refer to Figure 4 Preferably, in this embodiment, the cleaning shovel 3 has V-shaped rolled edges 301 on both sides. The V-shaped rolled edges 301 match the bridge expansion joint. The cleaning shovel 3 is designed with a "V" shaped opening based on the cross-sectional structure of the rubber waterstop of the bridge expansion joint. By optimizing the edge of the opening, the cleaning shovel 3 has V-shaped rolled edges 301 on both sides, which, together with the rubber directional wheel 4, play a limiting role, effectively preventing damage to the rubber waterstop during the use of the device. This effectively protects the rubber waterstop and improves cleaning efficiency.

[0030] This embodiment also discloses a practical method for cleaning bridge expansion joints:

[0031] First, place the bridge expansion joint cleaning tool, the cleaning shovel 3 and the rubber directional wheel 4, into the expansion joint. At this time, as follows... Figure 7 As shown, the rubber is oriented to the center of the expansion joint, so that the V-shaped rolled edge 301 of the cleaning shovel 3 abuts against the expansion joint. Then, according to the length of the hinged operating rod 1, after the adjustment is completed, the hinged operating rod 1 can be pushed to drive the steel shaft pulley 201 to roll, and the tool can be moved to clean the expansion joint. During the cleaning process, the debris in the expansion joint is scooped up by the cleaning shovel 3 and moved backward along the inclined surface of the cleaning shovel 3 into the collection box 2 for storage. During this process, when the debris in the cleaning shovel 3 does not automatically move to the collection box 2, press down on the telescopic rod 101 so that the limiting inclined opening is completely abutted against the top of the collection box 2. Continue to press down on the telescopic rod 101, and the bridge expansion joint cleaning tool will rotate around the steel shaft pulley 201 as the axis, driving the collection box 2 and the cleaning shovel 3 to tilt upward, so that the collected debris gathers at the rear end of the collection box 2. When the debris in the collection box 2 reaches the dumping amount, simply lift the hinged operating rod 1 of the tool. Since the hinge seat 103 is located at the rear center of the top of the collection box 2, the front end of the collection box 2 will rotate downward around the hinge seat 103 as the center, which can quickly dump the debris in the collection box 2. The operation is convenient.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
