Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a handheld pre-embedded steel bar cleaning device. Background Art

[0002] In bridge engineering, grouting sleeves are commonly used to connect prefabricated components. During the construction process, the connecting steel bars need to be embedded in the components in advance. When the components are poured with concrete, cement slurry can easily splash onto the embedded steel bars. At the same time, there is a certain time difference between the completion of the pouring of the components and the conditions for assembly. During this period, the embedded steel bars are prone to rust. Therefore, in order to ensure the quality of subsequent construction, the embedded steel bars must be cleaned before assembly.

[0003] At present, the cleaning of embedded steel bars at construction sites mainly adopts two methods: physical cleaning and chemical cleaning. The chemical cleaning method mainly uses chemical agents to react with rust to dissolve or convert the rusted materials into a form that is easy to remove. Although the cleaning speed is very fast, harmful gases and waste liquids may be generated during the cleaning process, causing pollution to the environment. The physical cleaning device disclosed in the prior art cleans the embedded steel bars with an exposed brush head. When the distance between two adjacent embedded steel bars is small, the cleaning of the brush head will be limited; at the same time, during the cleaning process, the rust residues that fall off the cleaning will splash, and there will be certain safety risks for the operators.

[0030] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a handheld pre-embedded steel bar cleaning device, including a handheld part 1 and a cleaning part 2, and the cleaning part 2 is connected to the handheld part 1. Among them, the cleaning part 2 includes a driving component 21 and a cleaning component 22, and the cleaning component 22 includes a rotating shell 221 and a cleaning brush 222. The rotating shell 221 surrounds a cleaning chamber 2210, and the embedded steel bar 100 to be cleaned extends into the cleaning chamber 2210. The cleaning brush 222 arranged on the side wall of the cleaning chamber 2210 contacts the outer wall of the embedded steel bar 100; the output end of the driving component 21 is connected to the rotating shell 221, and under the drive of the driving component 21, the rotating shell 221 is driven to rotate, thereby driving the cleaning brush 222 to generate friction with the embedded steel bar 100, so as to achieve the cleaning of the surface of the embedded steel bar 100. The handheld design of the device makes the operation simple and convenient, and can improve the cleaning efficiency; at the same time, the embedded steel bar 100 is cleaned in the cleaning chamber 2210, which can effectively prevent the splashing of the rust residue dropped by the cleaning, and ensure the safety of the operator.

[0032] Alternatively, if Figure 1 As shown, a plurality of cleaning brushes 222 are provided, and the plurality of cleaning brushes 222 are circumferentially spaced apart on the inner wall of the cleaning chamber 2210 to perform all-round cleaning of the embedded steel bars 100 extending into the cleaning chamber 2210 , thereby improving the working efficiency.

[0038] Optionally, the cleaning brush 222 is detachably disposed on the side wall of the cleaning chamber 2210. If the cleaning brush 222 is worn out after long-term use, it can be easily replaced later, thereby increasing the service life of the device.

[0039] Specifically, in this embodiment, the cleaning brushes 222 are arranged in rows, and each row of cleaning brushes 222 is arranged on a connecting plate, and the connecting plate is detachably arranged on the side wall of the cleaning chamber 2210. Exemplarily, the connecting plate can be detachably connected to the side wall of the cleaning chamber 2210 by fasteners such as bolts and screws, or a card slot is arranged on the side wall of the cleaning chamber 2210, and the connecting plate is carded in the card slot to achieve detachable connection between the cleaning brush 222 and the side wall of the cleaning chamber 2210.

[0040] Optionally, an anti-slip portion is provided on the outer side of the hand-held portion 1 to improve the stability of the operator holding the device and ensure the smooth progress of the cleaning operation.

[0041] Specifically, the anti-skid part is an anti-skid pad, such as a rubber pad, disposed on the outside of the handheld part 1; or, the anti-skid part is an anti-skid protrusion disposed on the outside of the handheld part 1, and the anti-skid protrusion can be a dot-shaped protrusion or a pattern protrusion of any shape, and its function is to increase the contact friction between the operator's hand and the handheld part 1 to prevent the device from moving. Its specific form refers to the prior art and is not specifically limited in this embodiment, as long as it can play a role in increasing friction.
