Description

Technical Field

[0001] This utility model relates to the field of cement floor construction technology, specifically a spiral cement floor construction device. Background Technology

[0002] In construction engineering, leveling the cement floor is a crucial step in ensuring a flat and stable foundation. The structural integrity and functional requirements of a completed building largely depend on the quality of its foundation. Leveling the floor creates this solid base. Furthermore, a level surface prevents construction problems caused by unevenness, ensures smooth progress of subsequent construction work, improves building quality, enhances the floor's load-bearing capacity and stability, compensates for foundation defects, improves the floor's wear resistance and durability, and prevents water seepage and dampness.

[0003] Currently, in the construction of cement floors, traditional tools for leveling cement floors consist of a support rod and an aluminum plate. Workers place the aluminum plate on the cement slurry surface and then push and pull the plate using the support rod to level the cement floor. Because the distance the aluminum plate moves varies, the rotation angle of the support rod also changes accordingly. To address this issue, commercially available cement floor leveling tools connect the support rod and aluminum plate only via a hinge. While this allows for adjustment of the support rod's rotation angle, it also makes the rotation too flexible and difficult to control, increasing the difficulty of leveling the cement floor and making it inconvenient for workers.

[0004] Therefore, there is a need to provide a spiral cement floor construction device to solve the above-mentioned problems. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a spiral cement floor construction device, which has the advantage of spiral control and adjustment of the rotation angle of the support rod, thereby reducing the flexibility of the support rod and making it easier for construction personnel to adjust it according to the needs. This solves the problem that when the support rod and aluminum plate are only connected by a hinge, the rotation of the support rod is too flexible and it is difficult to control the rotation angle, which increases the difficulty of cement floor construction and leveling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spiral cement flooring construction device, comprising an aluminum plate body, a support base installed on the top of the aluminum plate body, a semi-worm gear fixedly connected to the top of the support base, a rotating sleeve sleeved on the surface of the semi-worm gear, a receiving groove opened at the bottom of the rotating sleeve and located outside the semi-worm gear, a rotating groove opened at the top of the receiving groove, a bearing installed on the groove wall of the rotating groove, a worm gear rotatably connected inside the bearing and meshing with the semi-worm gear, a limit ring fixedly connected to the surface of the worm gear, a connecting pipe fixedly connected to the other end of the worm gear, and a washer provided on the outside of the limit ring and used in conjunction with the rotating groove.

[0007] As a preferred embodiment of this utility model, the surface of the semi-worm gear is provided with a rotating hole, the surface of the rotating sleeve is provided with a connecting port, a rotating shaft is rotatably connected inside the rotating hole, and a fastening cap is threaded to the other end of the rotating shaft, and the fastening cap is used in conjunction with the connecting port.

[0008] As a preferred embodiment of this utility model, the surface of the connecting pipe is symmetrically provided with fixing holes, and a positioning block is engaged inside the fixing hole.

[0009] As a preferred embodiment of this utility model, the inner wall of the rotating groove is provided with a groove, and a retaining ring is fixedly connected to the surface of the connecting pipe, and the retaining ring is rotatably connected to the groove.

[0010] As a preferred embodiment of this invention, the top of the rotating sleeve is provided with an oil passage hole, and a sealing plug is provided on the top of the oil passage hole.

[0011] As a preferred embodiment of this utility model, the top of the aluminum plate body is provided with four mounting grooves, and the top of the support base is provided with four mounting holes, and the four mounting holes correspond one-to-one with the four mounting grooves. The mounting holes are internally threaded with bolts, and the bolts are threadedly connected to the mounting grooves.

The rotating shaft 14 is rotatably connected inside the rotating hole 12, and the other end of the rotating shaft 14 is threadedly connected with a fastening cap 15, and the fastening cap 15 is used in conjunction with the connecting port 13.

[0024] As a technical optimization of this utility model, by setting the rotating hole 12, the connecting port 13, the rotating shaft 14 and the fastening cap 15, the rotating sleeve 4 can be deflected around the rotating shaft 14 as the center, and the position of the rotating sleeve 4 can be restricted to prevent it from shifting during use.

[0025] refer to Figure 1 and Figure 5 The surface of the connecting pipe 10 is symmetrically provided with fixing holes 16, and a positioning block 17 is engaged inside the fixing hole 16, and the positioning block 17 is V-shaped.

[0026] As a technical optimization of this utility model, by setting the fixing hole 16 and the positioning block 17, the connecting pipe 10 and the external support pipe can be positioned, so that the positioning block 17 can abut against the external support pipe, and the connecting pipe 10 can be prevented from rotating synchronously when it rotates.

[0027] refer to Figure 5 The inner wall of the rotating groove 6 is provided with a groove 18, and a retaining ring 19 is fixedly connected to the surface of the connecting pipe 10, and the retaining ring 19 is rotatably connected to the groove 18.

[0028] As a technical optimization of this utility model, the groove 18 and the retaining ring 19 can resist the running trajectory of the limiting ring 9 and the washer 11, thereby preventing the worm gear 8 from deviating outward on its own.

[0029] refer to Figure 1 , Figure 2 and Figure 5 The top of the rotating sleeve 4 is provided with an oil passage hole 20, and a sealing plug 21 is provided on the top of the oil passage hole 20.

[0030] As a technical optimization of this utility model, by setting the oil passage hole 20 and the sealing plug 21, lubricating oil can be injected into the oil passage hole 20, thereby reducing the friction coefficient between the half worm gear 3 and the worm 8, and thus extending the service life of the half worm gear 3 and the worm 8.

[0031] refer to Figure 1 The top of the aluminum plate body 1 is provided with four mounting grooves 22, and the top of the support base 2 is provided with four mounting holes 23.

[0033] The working principle and usage process of this utility model are as follows: When using this spiral cement floor construction device, first connect the external support rod to the connecting pipe 10, that is, align the connecting port of the external support rod with the connecting pipe 10 and insert it for fixation. During the connection process, press down the positioning block 17 to retract it into the fixing hole 16. After the external support rod is installed, use the rebound force of the positioning block 17 to lock it back into the fixing hole 16 and make it abut against the external support rod, so that the support rod and the connecting pipe 10 can rotate synchronously. Then, place the aluminum plate body 1 on the surface of the cement slurry, and then hold it by hand. The support rod pushes and pulls the aluminum plate body 1 to level the cement floor. When it is necessary to adjust the rotation angle of the support rod, simply rotate the support rod to drive the connecting pipe 10 to rotate, thereby allowing the worm gear 8 to rotate within the bearing 7. The worm gear 8 meshes with the semi-worm wheel 3 to drive the rotating sleeve 4 to rotate around the rotating shaft 14 on the support seat 2, thereby adjusting the rotation angle of the support rod. This allows for adjustment of the rotation angle of the support rod using a spiral control, reducing the difficulty of leveling the cement floor and making it easier for construction personnel to adjust according to their needs.
