Description

Technical Field

[0001] The invention belongs to the technical field of main structure construction of building engineering, and particularly relates to a top plate grinding tool. Background Art

[0002] As people pay more attention to the quality of houses, construction standards are gradually improving. The main construction is generally supported by wooden or aluminum formwork, but the flatness of the top plate or the joints of the formwork need to be polished and repaired twice when the delivery standard requirements are high. The traditional polishing and maintenance operation method is to stand on a horse stool to operate the angle grinder. This operation method is inefficient and difficult to construct, and the economic cost of investment is also high; there are also some that grind the top plate by building a grinding bracket to support the angle grinder. Working at a high altitude on the operating frame brings certain safety hazards to the operators, and setting up the grinding bracket requires a lot of manpower, material resources and materials, resulting in an increase in construction costs. In addition, the existing grinding device needs to keep pushing the bracket to move for grinding work, and the uniformity of the top plate grinding cannot be guaranteed. It is easy to grind unevenly, which leads to low flatness of the top plate. Summary of the invention

[0005] As a preferred technical solution of the present invention, the lifting mechanism includes a hydraulic cylinder and a wheel seat. The hydraulic cylinder is fixedly installed on the wheel seat along the axial direction, and universal wheels are fixedly installed around the bottom of the wheel seat. By moving the position of the wheel seat, the movement of the entire grinding tooling is driven.

[0006] As a preferred technical solution of the present invention, an auxiliary locking wire is provided on the horizontal transverse sleeve of the T-shaped sleeve for locking and fixing the T-shaped sleeve to the cross bar.

[0007] As a preferred technical solution of the present invention, a retaining platform is provided on the outer peripheral side of the axial sleeve of the T-shaped sleeve to prevent the axial sleeve on the T-shaped sleeve from falling downward into the main sleeve.

[0008] As a preferred technical solution of the present invention, rope seats are symmetrically and fixedly provided on the cross bars on both sides of the T-shaped sleeve.

[0009] As a preferred technical solution of the present invention, an outer sleeve is fixedly sleeved on the outer peripheral side of the main sleeve. The first bearing and the second bearing are fixedly sleeved on the outer peripheral side of the outer sleeve at intervals in the vertical direction. A ring-shaped fixing platform is provided on the main sleeve at the bottom of the outer sleeve.

[0010] As a preferred technical solution of the present invention, a first rope wheel area is formed on the circumferential side of the outer sleeve between the first bearing and the second bearing, and a second rope wheel area is formed on the circumferential side of the outer sleeve between the second bearing and the fixing platform.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present invention will be further described below with reference to the drawings and embodiments.

[0020] Embodiment 1:

[0021] Please refer to Figures 1-4, a top plate grinding tooling provided by the present invention includes a support mechanism, a lifting mechanism, and a grinding mechanism. The grinding mechanism is connected to the lifting mechanism through the support mechanism. The lifting mechanism includes a hydraulic cylinder 10 and a wheel seat 11. The hydraulic cylinder 10 is fixedly installed on the wheel seat 11 along the axial direction. Universal wheels are fixedly installed around the bottom of the wheel seat 11. By moving the position of the wheel seat, the movement of the entire grinding tooling is driven. Moreover, the universal wheels have a self-locking function, enabling them to be stably fixed along the axial direction. The support mechanism includes a support rod 13 and a main sleeve 9. The top end of the hydraulic cylinder 10 is fixedly connected to the bottom of the support rod 13 in a matching manner. By controlling the lifting of the hydraulic cylinder, the up-and-down movement of the support rod 13 is driven. The main sleeve 9 is sleeved on the outside of the support rod along the extending direction of the support rod. The support rod 13 extends vertically upward and its top end is connected to the grinding mechanism. The grinding mechanism includes a cross bar 1, a T-shaped sleeve 2, and a angle grinder 3. The T-shaped sleeve includes a horizontal transverse sleeve and an axial sleeve 6 in the vertical direction. The top end of the support rod 13 is sleeved in the axial sleeve 6 of the T-shaped sleeve in a matching manner. Moreover, the main sleeve 9 outside the support rod is also sleeved on the outside of the axial sleeve 6. A retaining platform 7 is provided on the outer peripheral side of the axial sleeve 6 of the T-shaped sleeve to prevent the axial sleeve 6 on the T-shaped sleeve from falling downward into the main sleeve 9. The cross bar 1 is sleeved in the horizontal sleeve of the T-shaped sleeve 2 in a matching manner, and the fixing or relative movement of the cross bar 1 and the T-shaped sleeve 2 is achieved through an auxiliary locking wire 21. Rope seats 22 are symmetrically and fixedly installed on the cross bar on both sides of the T-shaped sleeve. The angle grinder 3 is fixedly installed at one end of the cross bar 1 through a metal hoop. A hand-held rod 4 is provided at the other end of the cross bar opposite to the angle grinder. The hand-held rod 4 is fixedly connected to the cross bar through a mounting seat 5 fixed at the end of the cross bar. Moreover, the hand-held rod 4 is arranged vertically downward along the axial direction. The grinding position of the angle grinder on the cross bar is adjusted through the hand-held rod.

[0022] Through such a setting, it is possible to control the up-and-down movement of the support rod by starting the hydraulic cylinder and simultaneously drive the adjustment of the position of the angle grinder on the cross bar in the vertical direction. And it is possible to drive the rotation of the T-shaped sleeve through the hand-held rod 4, thereby driving the rotation of the cross bar and further realizing the change of the position of the angle grinder on the cross bar. In addition, an auxiliary locking wire 21 is also installed on the T-shaped sleeve. When the auxiliary locking wire 21 is tightened, the cross bar 1 is fixed to the T-shaped sleeve. In this way, only relative rotation can occur between the T-shaped sleeve and the cross bar. When the auxiliary locking wire 21 is loosened, not only can the T-shaped sleeve drive the cross bar to rotate relatively, but the cross bar 1 can also move left and right within the T-shaped sleeve. Thus, multi-directional adjustment of the angle grinder can be achieved without moving the entire tooling back and forth, ensuring the grinding efficiency of the top plate.

[0023] See Figure 2 and Figure 3, an outer sleeve 12 is fixedly sleeved on the outer peripheral side of the main sleeve 9 of the support mechanism. A first bearing 15 and a second bearing 18 are sleeved on the outer peripheral side of the outer sleeve 12 at intervals in the vertical direction. A ring-shaped fixing table 14 is provided on the main sleeve 9 at the bottom of the outer sleeve. The outer diameter of the fixing table 14 is larger than the outer diameter of the outer sleeve 12 to support and limit the position of the outer sleeve 12 and prevent it from falling downward. Thus, a first rope pulley area 19 is formed on the circumferential side of the outer sleeve between the first bearing 15 and the second bearing 18, and a second rope pulley area 20 is formed on the circumferential side of the outer sleeve between the second bearing 18 and the fixing table 14. Ropes are respectively wound on the outer peripheral sides of the outer sleeves in the first rope pulley area 19 and the second rope pulley area 20. The first bearing and the second bearing are used to ensure the restraint of the ropes in the rope pulley areas, so that the ropes are always wound in the two rope areas, and the winding directions of the ropes on the two rope areas are opposite. In this embodiment, the ropes wound on the inner and outer sleeves in the first rope pulley area 19 are in the clockwise direction, and the ropes wound on the inner and outer sleeves in the second rope pulley area 20 are in the counterclockwise direction. A main locking wire 8 is provided on the outer sleeve 12 above the first bearing 15 to realize the locking and loosening between the outer sleeve 12 and the main sleeve 9. That is, when the main locking wire 8 is locked, the main sleeve 9 and the outer sleeve 12 are fixed and there is no relative rotation between them. When the main locking wire 8 is loosened, the outer sleeve 12 can rotate relative to the main sleeve. Ring sleeves 16 are respectively fixedly sleeved on the outer peripheral sides of the first bearing 15 and the second bearing 18 to protect the two bearings, and connecting rods are respectively welded on the two ring sleeves, and wire guiding sleeves 17 are respectively welded at the ends of the connecting rods.

[0024] One end of the winding rope located within the first sheave area 19 is fixedly connected to the rope guide sleeve mounted on the first bearing 15, and the other end is fixedly connected to the rope seat 22 fixed to one side of the crossbar. One end of the winding rope located within the second sheave area 20 is fixedly connected to the rope guide sleeve mounted on the second bearing 18, and the other end is fixed to the rope seat 22 on the other side of the crossbar. With such an arrangement, since the winding directions of the ropes in the two sheave areas are opposite, when the crossbar rotates, the rope in the first sheave area 19 starts to be tightly wound around the outer sleeve from its originally relatively loose state, while the rope in the second sheave area 20 starts to become loose from its originally tightly wound state. As the crossbar continuously rotates, the ropes in the two sheave areas alternately loosen and tighten. In addition, since the rope in one sheave area is continuously tightly wound and one end of the rope is fixedly connected to the rope seat on the crossbar, as the rope is continuously tightly wound, the crossbar is driven by the rope seat to shift horizontally to one side. Conversely, the same is true. And during this process, due to the drive of the rope, the crossbar moves while rotating, that is, the crossbar performs a helical motion, and the diameter of each movement of the crossbar is the circumference of the outer sleeve. In this way, when there is a particularly protruding area on a certain surface of the top plate, the helical motion of driving the angle grinder can be used to achieve high-intensity repeated grinding of the protruding surface, making the grinding of the top plate more uniform and further ensuring the flatness of the top plate.

[0025] The top plate grinding tooling provided by the present invention can specifically achieve three working modes during use.

[0026] Mode 1: When the main lock wire is tightened and the auxiliary lock wire is loosened, the outer sleeve and the main sleeve are fixed, and there is no relative rotation between them. However, as the crossbar rotates, the ropes in the sheave areas are wound and loosened, thereby driving the relative movement between the crossbar and the T-shaped sleeve in the horizontal direction, achieving the helical motion of the crossbar and improving the uniformity of top plate grinding; Mode 2: When the main lock wire is loosened and the auxiliary lock wire is also loosened, when the crossbar rotates, it can drive the rotation of the outer sleeve, and the ropes do not tightly wind or loosen the outer sleeve. At this time, control the hand-held rod to make the crossbar move left and right or rotate, without performing a helical motion; Mode 3: When the main lock wire is loosened and the auxiliary lock wire is tightened, the crossbar can only rotate and cannot move left and right. When the crossbar rotates, it can drive the rotation of the outer sleeve, and the ropes do not tightly wind or loosen the outer sleeve, achieving grinding of the top plate along the circumference. The structure of the present invention is simple and easy to operate, with high structural strength, can conveniently control the uniform grinding of uneven positions on the top plate, and does not need to continuously move the entire tooling, ensuring the stability of the structure during the grinding process.

[0027] Embodiment 2:

[0028] On the basis of Embodiment 1, the same parts as those in Embodiment 1 will not be described in detail. The differences are as follows: A horizontal lock sleeve is hinged through a pin shaft axially under the T-shaped sleeve. The horizontal lock sleeve includes a disc with an open top end and a vertical sleeve integrally fixed to the lower end of the disc. A lock wire is also provided on the horizontal lock sleeve. By moving the position of the horizontal lock sleeve up and down and combining the screwing and loosening of the lock wire, the rotation of the T-shaped sleeve is further adjusted, causing it to undergo a flipping motion to achieve grinding work on the top plate at more angles. Specifically, when the horizontal lock sleeve moves upward and the lock wire is fixed to the axial sleeve of the T-shaped sleeve after passing through the pin shaft, the T-shaped sleeve will not rotate relatively; when the horizontal lock sleeve moves downward to below the pin shaft, the T-shaped sleeve can undergo a flipping motion through the pin shaft, thereby driving the adjustment of the orientation of the angle grinder.

[0029] Embodiment 3:

[0030] On the basis of Embodiment 1, the same parts as those in Embodiment 1 will not be described in detail. The differences are as follows: In order to further ensure the stability of the T-shaped sleeve when driving the cross bar to rotate and enhance the grinding effect of the angle grinder on the top plate, a bearing is further fitted in the main sleeve in a matching manner, which can ensure the enhancement of the structural stability when the axial sleeve rotates.

[0031] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
