Description

Technical Field

[0001] The utility model relates to the field of expansion joint cleaning, in particular to a bridge expansion joint cleaning device. Background Art

[0002] In order to meet the requirements of bridge deck deformation, expansion joints are usually set between the two beam ends, between the beam end and the abutment, or at the hinged position of the bridge. The expansion joint is mainly formed by the expansion joint base on both sides. The lower inner side of the expansion joint base is used for waterproofing. The expansion joint space above the waterstop will accumulate a lot of impurities and dust, affecting the free expansion and contraction of the bridge end.

[0003] The accumulated impurities and dust will become harder after being washed by rainwater and dried later. Cleaning these impurities requires manual use of a small shovel. Not only is the cleaning speed slow, but the depth of insertion of the shovel is difficult to control during cleaning, which can easily damage the waterstop. Once the rubber strip of the waterstop is damaged, rainwater will flow into the abutments and piers through the seams, causing varying degrees of aging of the bearing rubber. Utility Model Content

[0007] Further optionally, the rolling support frame includes a fixed sleeve fixed on the front end of the handle push rod, support shafts are symmetrically fixed on both sides of the fixed sleeve, the bottom of the support shaft is rotatably connected to a support wheel supported on the edge of the expansion joint base, and a limit column with different diameters that can be replaced is arranged at the lower center of the support wheel.

[0008] Further optionally, the top of the limiting column is threadedly connected to a threaded sleeve provided on the supporting wheel through a threaded rod.

[0009] Further optionally, the upper part of the loosening shovel is fixedly connected to the front end of the handle push rod through a connecting block.

[0010] Further optionally, the loosening shovel is set as a frame-shaped shovel, the bottom of the frame-shaped shovel matches the shape of the waterstop in the expansion joint, and the front end section of the frame-shaped shovel is set at an inclination angle.

[0011] Further optionally, a plurality of upwardly curved flip shovel plates are fixedly provided at the rear end of the bottom of the loosening shovel.

[0012] Further optionally, the width of the loosening shovel is 2-5 mm smaller than the width of the expansion joint.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0020] like Figure 1 As shown, the bridge expansion joint cleaning device includes a handle push rod 1, which is used for hand-held operation by personnel. A rolling support frame supported on the edge of the expansion joint base 9 is arranged at the front end of the handle push rod 1, and a loosening shovel 7 for loosening and removing impurities in the expansion joint 10 is arranged on one side of the rolling support frame. The loosening shovel 7 is pulled to clean the impurities in the expansion joint, so that harder dust impurities can be loosened for subsequent quick cleaning.

[0021] The rolling support frame includes a fixed sleeve 2 fixed on the front end of the handle push rod 1, and support shafts 3 are symmetrically fixed on both sides of the fixed sleeve 2. The bottom of the support shaft 3 is rotatably connected to a support wheel 4 supported on the edge of the expansion joint base 9. A limit column 5 with different diameters that can be replaced is arranged in the lower center of the support wheel 4. The limit column 5 is clamped on the inner edge of the expansion joint base 9 to avoid shaking, and the support wheel 4 plays a supporting role to prevent the loose shovel 7 from being damaged by the height change of the loose shovel 7.

[0022] like Figure 2As shown, the top of the limit column 5 is threadedly connected to the threaded sleeve provided on the support wheel 4 through the threaded rod 51. By replacing the limit column 5 through the thread, the limit column 5 can better adapt to the expansion joints 10 of different widths, ensuring the fit between the limit column 5 and the side edge of the expansion joint base 9. The upper part of the loosening shovel 7 is fixedly connected to the front end of the handle push rod 1 through the connecting block 6.

[0023] The loosening shovel 7 is set as a frame-shaped shovel, the bottom of which matches the shape of the water stop 11 in the expansion joint 10. The front section of the frame-shaped shovel is set at an inclination angle, and its edge is sharper and the cutting is smoother. A plurality of upwardly curved flip shovel plates 8 are fixedly set at the rear end of the bottom of the loosening shovel 7, and the flip shovel plates 8 flip the cut and cleaned dust to achieve the separation of dust impurities.

[0024] The width of the loosening shovel 7 is 2-5 mm smaller than the width of the expansion joint 10 , which can ensure that the loosening shovel 7 extends into the expansion joint 10 .

[0025] The implementation principle of a bridge expansion joint cleaning device in the embodiment of the present application is:

[0026] When cleaning the dust and impurities in the bridge expansion joint 10 (such as Figure 3 , 4 As shown), the loosening shovel 7 of the device is inserted into the expansion joint 10, and the two support wheels 4 of the rolling support frame are supported on the edge of the expansion joint base 9, and the limit column 5 at the lower part of the support wheel 4 is stuck on the inner edge of the expansion joint base 9 to achieve positioning support for the loosening shovel 7, avoiding damage to the water stop belt 11 during subsequent movement and cleaning;

[0027] Then the operator pushes the handle push rod 1 with force, and the support wheel 4 on the support shaft 3 rotates to realize the rapid movement of the device, avoiding dry friction and pushing the device more labor-saving, so that the loosening shovel 7 moves along the expansion joint 10, and the loosening shovel 7 cuts the impurities in the expansion joint 10, and the flipping shovel plate 8 at the rear end of the loosening shovel 7 will flip the cut impurity blocks separately, so as to realize the flipping and separation of the impurities. After flipping, a brush or vacuum cleaner is used for cleaning and adsorption, and the efficiency and cost of cleaning dust and impurities are improved.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
