DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0031] The utility model discloses a hinged seam cleaning device, wherein, with reference to Figure 6 The hinged joint 400 is the gap between the two groups of simply supported beams 40 .

[0032] Reference Figures 1 to 6 The hinged seam cleaning device includes two parts: a handheld platform 10 and a telescopic frame 20.

[0033] Among them, a power machine 11 is provided on the handheld platform 10. The power machine 11 is usually a motor. The lower end of the power machine 11 is connected to a rotating shaft 12 that can be vertically inserted into the hinged seam 400. The power machine 11 drives the rotation of the rotating shaft 12. At the same time, two sets of armrests 100 are provided on the handheld platform 10. When held with both hands, the entire device can be kept vertically inserted in the hinged seam 400.

[0034] Reference Figure 1 and Figure 2 The telescopic frame 20 includes a plurality of articulated arms 200 disposed around the rotating shaft 12 . In this embodiment, six groups of articulated arms 200 are disposed at even intervals around the axis of the rotating shaft 12 .

[0035] Among them, each group of articulated arms 200 includes a lower arm section 2000 and an upper arm section 2001 that are hinged to each other, and each group of lower arm sections 2000 is hinged on the rotating shaft 12 and cannot move up and down; in this embodiment, a group of connectors 202 is fixed on the rotating shaft 12, and the lower ends of the six groups of lower arm sections 2000 are hinged on the connectors 202; a group of sliding sleeves 201 is slidably passed through the rotating shaft 12, and the six groups of upper arm sections 2001 are hinged on the sliding sleeves 201.

[0036] In addition, a brush 21 for cleaning the hinged gap 400 is provided on the outer side surface of each set of hinged arms 200 .

[0037] When in use, the rotating shaft 12 with the telescopic frame 20 is inserted into the hinged joint, and the power machine 11 is started. Driven by the power machine 11, the rotating shaft 12 drives the telescopic frame 20 to rotate. Due to the centrifugal force, the hinge of the lower arm section 2000 and the upper arm section 2001 of the telescopic frame 20 moves radially of the rotating shaft 12, so that the upper arm section 2001 and the lower arm section 2000 are both attached to the inner wall of the hinged joint 400. At this time, the brush 21 on the telescopic frame 20 cleans the concrete debris and moss on the inner wall of the hinged joint 400. After cleaning, rinse with water. After the moisture on the inner wall of the hinged joint is blown dry, grouting can be carried out.

[0038] In the above embodiment, the lower arm section 2000 and the upper arm section 2001 fit the inner wall of the hinged seam 400 under the centrifugal effect. Therefore, the counterweights of the lower arm section 2000 and the upper arm section 2001 can be increased as needed.

[0039] After use, the hinged seam cleaning device can be pulled out from the hinged seam 400. During the process, the outer wall of the upper arm section 2001 slides in contact with the inner wall of the hinged seam 400, so that the hinge between the lower arm section 2000 and the upper arm section 2001 automatically contracts toward the centripetal.

[0040] In another embodiment, a group of tension springs 22 are further sleeved on the rotating shaft 12, the upper end of the tension spring 22 is fixed to the outer wall of the rotating shaft 12, and the lower end of the tension spring 22 is connected to the sliding sleeve 201; the centrifugal movement of the telescopic frame 20 needs to overcome the tension of the tension spring 22, which can be achieved by increasing the counterweight of the lower arm section 2000 and the upper arm section 2001; when the rotating shaft 12 stops rotating, the tension spring 22 drives the upper end of the upper arm section 2001 to slide up automatically, so that the hinge of the lower arm section 2000 and the upper arm section 2001 can automatically contract centripetally, and finally, each group of articulated arms 200 are in contact with the outer wall of the rotating shaft 12.

[0041] In addition, refer to Figures 1 to 4 In one embodiment, a group of connecting shafts 13 can be telescopically arranged at the lower end of the rotating shaft 12, and the connecting shaft 13 is penetrated in the rotating shaft 12, and the upper end of the connecting shaft 13 is hinged with two groups of connecting rods 130, and the connecting rods 130 pass through the side wall of the rotating shaft 12 to extend to the outside of the rotating shaft 12; wherein, the upper ends of the two groups of connecting rods 130 are respectively hinged to the upper ends of a group of lower arm sections 2000, and when the telescopic frame 20 rotates centrifugally, the connecting shaft 13 is driven to move upward through the connecting rods 130.

[0042] Reference Figure 2 and Figure 3 A group of vertical plates 30 that can pass through the gap at the lower end of the hinged seam 400 are provided below the rotating shaft 12. Two groups of inverted universal wheels 31 are provided on the upper surface of the vertical plate 30 in the horizontal direction, and the two groups of universal wheels 31 are arranged at both ends of the vertical plate 30 in the horizontal direction. The thickness of the universal wheels 31 is not greater than the thickness of the vertical plate 30; the rotating shaft 12 includes a rotating shaft body 120 and a vertical plate 121 installed at the lower end of the rotating shaft body 120, and the vertical plate 121 is rotatably connected to the vertical plate 30.

[0043] Reference Figure 2 Before the hinged joint cleaning device is inserted into the hinged joint 400 , the vertical plate 30 , the two sets of universal wheels 31 and the vertical plate 121 are located in the same plane. At this time, the vertical plate 30 and the two sets of universal wheels 31 can easily pass through the gap at the lower end of the hinged joint 400 and extend to the bottom of the simply supported beam 40 .

[0044] Reference Figure 4 and Figure 5, a set of spiral rods 14 are provided at the lower end of the connecting shaft 13, and a set of matching holes 3200 matching the spiral rods 14 are provided in the vertical plate 30, and the spiral rods 14 are inserted into the matching holes 3200; when the telescopic frame 20 centrifugally drives the connecting shaft 13 to move upward, when the connecting shaft 13 drives the spiral rod 14 to move upward to the maximum position, the vertical plate 30 is driven to rotate 90°. At this time, refer to Figure 1 and Figure 6 The board surface where the vertical board 30 is located is perpendicular to the board surface where the vertical board 121 is located. At this time, the two sets of universal wheels 31 are hooked and attached to the bottom of the precast beams on both sides of the hinged joint 400.

[0045] Reference Figure 6 Since the universal wheel 31 has the characteristic of self-steering, at this time, it is only necessary to move the hinged joint cleaning device along the length direction of the hinged joint 400, and the universal wheel 31 can roll along the length direction of the hinged joint 400; since the hinged joint cleaning process requires high-speed rotation, the telescopic frame 20 is prone to shaking when contacting the inner wall of the hinged joint 400, causing it to tilt left or right, making it easy to clean the roughened surface. The above design ensures that during the operation of the hinged joint cleaning device, the upper end of the hinged joint cleaning device is supported by the handheld platform 10, and the lower end is supported and guided by the universal wheel 31, so that the hinged joint cleaning device can always remain in a vertical state during the movement, which is convenient for construction personnel to operate and can also improve the cleaning efficiency.

[0046] The specific connection form between the vertical plate 121 and the vertical plate 30 is described as follows:

[0047] Reference Figure 4 and Figure 5 The lower end of the connecting shaft 13 is passed through the cavity of the vertical plate 121, and a group of limit baffles 1210 are also provided in the vertical plate 121. The connecting shaft 13 is provided with a group of convex rings 131 located below the limit baffles 1210. When the convex rings 131 abut against the lower end surface of the limit baffles 1210, the upward movement distance of the connecting shaft 13 can be limited to ensure that the vertical plate 30 is rotated exactly 90°.

[0048] In addition, the lower end of the vertical plate 121 is provided with an inner tube sleeve 1211 inserted into the cavity of the vertical plate 30, and the lower end of the inner tube sleeve 1211 is provided with a retaining ring 1212. The cavity of the vertical plate 30 is provided with an outer tube sleeve 32 sleeved on the inner tube sleeve 1211, and an end face bearing 15 is provided between the convex ring 131 and the top of the cavity of the vertical plate 30, and the end face bearing 15 is sleeved on the inner tube sleeve 1211. Such a design can ensure the rotational connection relationship between the vertical plate 121 and the vertical plate 30.

[0049] In addition, the outer tube sleeve 32 is installed with a core block 320 located below the retaining ring 1212, and the matching hole 3200 is opened in the middle of the core block 320, and the core block 320 and the outer tube sleeve 32 are formed by an integral injection molding process.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
