Description

Technical Field

[0001] This utility model relates to the technical field of equipment for cleaning junction boxes during the construction of steel truss floor slabs, and in particular to a device for cleaning pre-embedded junction boxes. Background Technology

[0002] In the field of reinforced truss floor slab construction, the technology for cleaning pre-embedded junction boxes has continuously improved with the development of building technology. In recent years, with the advancement of building industrialization, the requirements for construction efficiency and safety have been increasing, and traditional manual methods for cleaning junction boxes have gradually become unable to meet the needs of modern construction. Against this backdrop, the development of pre-embedded junction box cleaning technology is particularly important, as it not only relates to construction efficiency but also directly affects the safety of construction workers and the quality of the project.

[0003] While some technologies have attempted to address the issue of cleaning embedded junction boxes, existing techniques still have numerous shortcomings. Currently, the commonly used method in construction involves screwing through the steel floor slab to locate the junction box, then searching for the screw on the floor below, and finally cleaning it by mechanically tapping it. This method presents significant safety hazards, such as flying debris that could injure workers, and inaccurate tapping that can leave marks on areas without junction boxes, resulting in material waste and structural damage. Furthermore, manual tapping is inefficient and cannot guarantee cleaning quality, often leaving behind incompletely cleaned metal sheets, affecting subsequent construction progress. These problems not only increase construction costs but also threaten the safety of construction workers, highlighting the deficiencies of existing technologies in terms of safety, accuracy, and efficiency.

[0004] How to solve the above problems is the research topic of this plan. Utility Model Content

[0005] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, this utility model provides a pre-embedded junction box cleaning device.

[0006] The technical solution includes a shell and a garbage collection box, wherein the shell is provided with a screw positioning mechanism and a cleaning and cutting mechanism;

[0007] The cleaning and cutting mechanism includes a moving track, a slider, a connecting rod, an electric push rod, a motor, and a blade for cutting the sheet metal of the floor decking, which is set at the end of the motor output shaft.

[0008] The screw positioning mechanism includes a positioning seat and a screw positioning hole formed on the positioning seat;

[0009] The shell is configured as a trapezoidal body with a top opening at the top and a bottom opening at the bottom, and the four side walls of the shell between the top and bottom openings;

[0010] The garbage collection box is rectangular with a collection port at one end, which is opposite to the bottom opening of the shell.

[0011] The positioning seats are fixedly mounted on the four outer walls at the top opening of the housing;

[0012] The end face of the positioning seat is flush with the surface of the top opening.

[0013] The moving track is provided on the four inner side walls at the bottom opening of the housing. The moving track has a transverse groove on the side facing the inner side wall of the housing. A lead screw is provided in the groove. The slider and electric push rod are respectively provided on the connecting rod.

[0014] The slider has a through hole, and the lead screw is threadedly connected to the slider.

[0015] The fixed end of the electric push rod is fixed to the connecting rod;

[0016] Both ends of the moving track are provided with uprights, and the uprights are fixedly connected to the inner sidewall of the housing;

[0017] The lead screw is rotatably connected to both ends of the moving track. The lead screw is driven to rotate by its own drive motor, which is existing technology and will not be described in detail here.

[0018] The motor is fixedly connected to the telescopic end of the electric push rod, and the output shaft of the motor is fixedly connected coaxially with the rotation center of the blade.

[0019] When the motor starts, it drives the blade to rotate. At the same time, the lead screw rotates, which drives the slider to move laterally, thereby driving the blade to perform a reciprocating motion laterally.

[0020] The electric actuator is activated, moving the blade to the sheet metal of the floor deck for cutting.

[0021] The moving track and connecting rod are both arranged parallel to the inner wall of the housing.

[0022] A connecting plate is provided at the bottom opening of the housing, and four connecting plates form a rectangular frame. Buckle hooks are provided on the outer walls of two of the connecting plates.

[0023] The two outer walls of the garbage collection box are provided with buckles, which are engaged and matched with buckle hooks.

[0024] The waste collection box has handles on its two outer walls.

[0025] After the staff saw the screws embedded in the roof, they aligned the screw positioning holes with the screws, started the motor, and drove the blade to rotate. At the same time, the lead screw rotated, which drove the slider to move laterally, thereby driving the blade to make a reciprocating motion laterally.

[0026] The electric actuator is activated, moving the blade to the sheet metal of the floor deck for cutting.

[0027] The cut-off sheet metal fell into the trash collection box.

[0028] The location of the junction box can be accurately located through the screw positioning holes, and the sheet metal can be cut with a blade to clean the junction box. Using this device can effectively protect the operator and eliminate the possibility of mechanical impact during this work; accurate positioning can reduce damage to the floor deck where there is no junction box; and the garbage collection box can ensure that the site is cleaned up after the work is completed, reducing garbage pollution.

The cleaning device uses screw positioning holes aligned with screws, the motor starts, drives the blade to rotate, and at the same time, the lead screw rotates, drives the slider to move laterally, thereby driving the blade to make lateral reciprocating motion.

[0030] The electric actuator activates, moving the blade to the sheet metal of the floor deck for cutting. The cut sheet metal falls into the waste collection device, avoiding the problem of debris falling during manual cleaning and subsequent sweeping. Its advantages are mainly reflected in the following aspects:

[0031] Improved safety: Precise screw positioning and blade cutting action prevent objects from flying out due to manual knocking, thus protecting operators from accidental injury and significantly improving construction safety.

[0032] Improved cleaning efficiency: The motor drives the blade to rotate for cutting, and the screw and slider work together to drive the blade to reciprocate. Compared with manual knocking, the cleaning speed is greatly accelerated and the construction efficiency is improved.
