Description

Technical Field

[0001] The invention relates to the technical field of cleaning components, in particular to a device for cleaning soil on a steel support surface. Background Art

[0002] In foundation pits and underground tunnel projects, the ground-connected wall-steel support system is often used. The steel support structure can ensure that the ground stress is still balanced after being disturbed by external forces, prevent the collapse of foundation pits and tunnels, and ensure normal construction. Due to the alternating excavation and support during the construction process, a large amount of soil often falls on the surface of the steel support, which will cause corrosion to the steel structure after a long time, affecting the ultimate bearing capacity and reuse of the steel support structure. At present, manual removal of surface soil is often used, which is very unsafe and prone to accidents. At the same time, the steel support structure is often large, the removal efficiency is limited, and the time cost is high. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a soil cleaning device for a steel support surface, which has the characteristics of being easy to use and highly efficient.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a steel support surface soil cleaning device, which is used to clean circular columns. The steel support surface soil cleaning device includes a clamping ring, which includes two semi-circles that cooperate with each other, bristles are provided on the inner side of the semi-circle, a rigid rod extending upward is fixed in the middle of the upper side surface, and electromagnetic connecting plates that cooperate with each other are provided at the ends of the semi-circles, and a cable is connected to the middle of the semi-circle.

[0005] A dovetail groove is provided on the side surface of the semicircle close to the center of the semicircle, and a plurality of dovetail blocks are provided in the dovetail groove. Adjacent dovetail blocks are connected together by a connecting rope. At the same time, a tension spring is connected between the outermost dovetail block and the corresponding end of the semicircle, and a pull rope extending upward is connected to the middle part of the connecting rope between the two middle dovetail blocks. A through hole is provided on the upper side wall in the middle part of the dovetail groove, and the pull rope passes through the corresponding through hole from bottom to top, and bristles are provided on the dovetail block.

[0006] A handle extending to one side is fixed on the upper end of the rigid rod, one end of the handle is hinged to one end of the handle, and the upper end of the pull rope is connected to the middle part of the handle.

[0007] The rigid rod is provided with a concealed groove extending up and down, and the pull rope is located in the concealed groove.

[0008] The bristles are attached to the corresponding dovetail blocks by Velcro.

[0009] After adopting the above structure, the advantages of the present invention over the prior art are: easy to use and high efficiency. The soil cleaning device on the surface of the steel support of the present invention uses two semicircles to form a complete ring, and the two semicircles are connected together by electromagnetic attraction, which is not only easy to assemble, but also can conveniently drive the clamping ring to rotate through the rigid rod, or move the bristles by squeezing the handle, so that the circular column can be cleaned, which is very convenient.

[0021] For example, see Figures 1 to 3 Shown: A soil cleaning device for the steel support surface is used to clean round columns, and the columns can be steel support structures.

[0022] Specifically:

[0023] The soil cleaning device on the steel support surface includes a clamping ring 10. The clamping ring 10 includes two semicircles 11 that cooperate with each other. That is, the two semicircles 11 are connected end to end to form a closed ring so that they can hug the outside of the column. Bristles 60 are provided on the inner side of the semicircle 11. The inner side of the semicircle 11 refers to a side surface close to its center position. A rigid rod 12 extending upward is fixed to the middle of the upper side surface of the semicircle 11. Electromagnetic connecting plates 13 that cooperate with each other are provided at the ends of the semicircle 11. That is, electromagnetic connecting plates 13 are provided at both ends of the semicircle 11, and the polarities of the two electromagnetic connecting plates 13 at the head and tail are opposite. After power is turned on, the electromagnetic connecting plates 13 are energized and have magnetism, and can attract each other, so that the two semicircles 11 form a closed ring. Of course, one of the two electromagnetic connecting plates 13 that cooperate with each other can be a near-magnetic material such as iron. One of the two electromagnetic connection plates 13 that attract each other may have a protruding portion protruding outward, and the other may have a recessed portion recessed inward, and the protruding portion can be stuck in the recessed portion, so that the two semicircles 11 connected together are more stable. A cable 14 is connected to the middle of the semicircle 11. In this way, after the two semicircles 11 are docked and held on the outside of the column, the circumferential surface of the column can be cleaned by only pulling the cable 14, or by operating the clamping ring 10 to rotate or move up and down through the rigid rod 12, which is more convenient.

[0024] Optimized:

[0025] A dovetail groove 15 is provided on the side of the semicircle 11 close to the center of the semicircle 11, and the opening of the dovetail groove 15 faces the center of the semicircle 11. A plurality of dovetail blocks 20 are provided in the dovetail groove 15, and adjacent dovetail blocks 20 are connected together by connecting ropes 21. At the same time, a tension spring 30 is connected between the dovetail block 20 located on the outermost side and the corresponding end of the semicircle 11. That is, the dovetail block 20 has a tendency to move to both sides of the dovetail groove 15. A pull rope 40 extending upward is connected to the middle of the connecting rope 21 between the two middle dovetail blocks 20. The connecting rope 21 connected to the pull rope 40 can be slightly longer than other connecting ropes 21. A through hole 151 is provided on the upper side wall of the middle part of the dovetail groove 15, and the pull rope 40 passes through the corresponding through hole 151 from bottom to top. And, the bristles 60 are arranged on the dovetail block 20. In this way, after the clamping ring 10 is clamped on the column, the dovetail block 20 can be repeatedly moved along the dovetail groove 15 by only pulling and loosening the pull rope 40, so as to facilitate cleaning of the column.

[0026] A handle 51 extending to one side is fixed to the upper end of the rigid rod 12, one end of a handle 52 is hinged to one end of the handle 51, and the upper end of the pull rope 40 is connected to the middle of the handle 52. That is, the pull rope 40 can be driven to move up and down by repeatedly pinching and releasing the handle 52, making the operation more convenient.

[0027] The rigid rod 12 is provided with a concealed groove 121 extending up and down, and the pull rope 40 is located in the concealed groove 121. The concealed groove 121 can be formed by arranging a plurality of guide rings from bottom to top on the rigid rod 12, so that the pull rope 40 is more regular.

[0028] The bristles 60 are adhered to the corresponding dovetail blocks 20 by Velcro. Like this, it is convenient to replace the bristles 60.

[0029] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
