Description

Technical Field

[0001] The utility model relates to the technical field of stone hoisting, and more specifically, to a stone hoisting clamp. Background Art

[0002] Stone is a high-end building decoration material that is widely used in interior and exterior decoration design, curtain wall decoration and public facility construction. During the construction of curbstones in municipal engineering projects, due to the heavy weight of curbstones and other stones, the stones must be transported to the designated location before manual installation, which is time-consuming and labor-intensive. At the same time, the installation accuracy is poor and the efficiency is low. Therefore, a lifting fixture is needed to clamp and lift the stones.

[0003] A search revealed a Chinese patent application with publication number CN218261610U, which discloses a stone clamp. The clamp consists of two L-shaped clamps, the long sides of which are pivotally connected by a pivot. The short ends of the two L-shaped clamps are provided with inward-facing clamping surfaces. The long ends of the two L-shaped clamps are connected by a rigid yet flexible connector. This structure is suitable for handling stones of varying sizes, is easy to use, and can significantly shorten stone lifting time.

[0004] However, in actual use, this structure adopts two interactively hinged L-shaped clamping edges to clamp the two ends of the stone, and uses rubber friction pads to increase friction. However, it is impossible to lift the bottom of the stone. Once the rubber friction pad is worn or the clamping force is insufficient, it is easy to cause the risk of the stone falling, and the safety is not high. In view of this, the utility model proposes a stone lifting clamp. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a stone hoisting clamp to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stone lifting clamp, comprising a pulley block, a suspension hook, a lifting chain, a diamond frame and two oppositely arranged chucks, the suspension hook being movably mounted on the surface of the pulley block, the lifting chain being movably mounted on the bottom of the suspension hook, the diamond frame being movably mounted on the bottom of the lifting chain, the chuck being at the bottom of the diamond frame, an axle pin being provided at the connection between the chuck and the diamond frame, and being movably connected by the axle pin, an anti-slip pad being provided at one end of the chuck, the surface of the anti-slip pad being provided with anti-slip grooves, and the two chucks being able to move left and right relative to each other at the diamond frame.

[0007] It can be seen that in the above structure, during the hoisting of the stone, the diamond frame can enable the two clamps to be located at both ends of the stone for clamping, thereby achieving the purpose of hoisting the stone.

[0008] The top end of the adjusting screw is installed in the inner wall of the adjusting screw slot, and the bottom end of the adjusting screw slot is installed in the outer wall of the adjusting screw slot. A lifting plate is provided at one end of the threaded block, and a movable plate is provided at one end of the lifting plate inside the sleeve, and a feed screw is provided at one end of the sleeve. The threaded block is installed in the inner wall of the sleeve and the threaded block is connected with the external thread of the adjusting screw, and the threaded block is fixedly connected to the support plate. The sleeve is hollow, and one end of the lifting plate is slidably connected to the hollow sleeve, and one end of the feed screw is connected to the movable plate, and the feed screw is threadedly connected to the sleeve.

[0009] The technical effects and advantages of this utility model are:

[0010] 1. By setting up an auxiliary lifting structure, the adjusting screw drives the threaded block to slide inside the installation groove, so that the support plate drives the lifting plate at the sleeve plate to be at the bottom position of the stone, ensuring that the lifting plate can lift the bottom of the stone. In addition, the feed screw drives the movable plate to slide inside the hollow sleeve plate and drives the lifting plate to extend outward from the inside of the sleeve plate, thereby increasing the lifting range of the lifting plate at the bottom of the stone, thereby avoiding the risk of the stone falling during hoisting;

[0011] 2. In the process of hoisting the stone through the pulley group, the hoisting chain will lift the diamond frame, and the movable hinge of the diamond frame can drive the two chucks to approach each other, and then the two chucks close to each other clamp the stone and hoist it. The overall size can be adjusted, the clamp is firm and reliable, which is convenient for hoisting the stone and improves the hoisting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] As attached Figure 1-5 The stone lifting clamp shown includes a pulley block 1, a suspension hook 2, a lifting chain 3, a diamond frame 4 and two oppositely arranged chucks 5. The suspension hook 2 is movably mounted on the surface of the pulley block 1, the lifting chain 3 is movably mounted on the bottom of the suspension hook 2, the diamond frame 4 is movably mounted on the bottom of the lifting chain 3, the chuck 5 is at the bottom of the diamond frame 4, and the connection between the chuck 5 and the diamond frame 4 is provided with an axle pin 14, and is movably connected through the axle pin 14. One end of the chuck 5 is provided with an anti-slip pad 15, and the surface of the anti-slip pad 15 is provided with anti-slip grooves. The two chucks 5 can move left and right relative to each other at the diamond frame 4.

[0020] Specifically, in this structure, when the stone is hoisted, the pulley group 1 is connected to the hoisting equipment, and the two chucks 5 are at the two ends of the stone. During the hoisting process by the hoisting equipment, the diamond frame 4 will be movable and hinged, thereby driving the two chucks 5 to approach each other, and then the two chucks 5 close to each other clamp the stone and hoist it. After the hoisting is completed, the two chucks 5 are released, and the overall size can be adjusted. The clamp is firm and reliable.

[0021] In a specific embodiment, as shown in the attached Figure 2 、 3As shown in , 4 and 5, the outer wall of the rhombus frame 4 is provided with an auxiliary lifting structure, which includes an adjusting screw 6. The outer wall of the rhombus frame 4 is provided with a mounting groove 7, and the adjusting screw 6 is installed inside the mounting groove 7. A threaded block 8 is provided on the outside of the adjusting screw 6, and a support plate 9 is provided at one end of the threaded block 8. A sleeve 10 is provided at the bottom end of the support plate 9, and a lifting plate 11 is provided at one end of the sleeve 10. A movable plate 12 is provided at one end of the lifting plate 11 inside the sleeve 10, and a feed screw 13 is provided at one end of the movable plate 12. The threaded block 8 is installed inside the mounting groove 7, and the threaded block 8 is connected to the external thread of the adjusting screw 6, and the threaded block 8 is fixedly connected to the support plate 9. The sleeve 10 is hollow, and one end of the lifting plate 11 is slidably connected to the inside of the hollow sleeve 10. One end of the feed screw 13 is connected to the movable plate 12, and the feed screw 13 is threadedly connected to the sleeve 10.

[0022] Specifically, in this structure, in order to improve the stability of the stone during hoisting and avoid the risk of the stone falling, when the two chucks 5 clamp the two ends of the stone and hoist it, the operator drives the threaded block 8 to slide inside the installation groove 7 by adjusting the screw 6 according to the height of the stone itself, so that the support plate 9 drives the lifting plate 11 at the sleeve plate 10 to the bottom position of the stone, ensuring that the lifting plate 11 can lift the bottom of the stone;

[0023] At the same time, by rotating the feed screw 13, the feed screw 13 drives the movable plate 12 to slide inside the hollow sleeve 10, and drives the lifting plate 11 to extend outward from the inside of the sleeve 10, thereby increasing the lifting range of the lifting plate 11 at the bottom of the stone. The setting of this structure can adjust the two lifting plates 11 to the bottom of the stone during the process of clamping and lifting the stone through the two chucks 5, and lift the stone at the bottom of the stone, thereby improving the stability of the stone during lifting, and avoiding the risk of the stone falling off between the two chucks 5 during the lifting process.

[0024] Working principle of this utility model:

[0025] When the above structure is used, during the process of hoisting the stone, the two clamps 5 are placed at the two ends of the stone. When the stone is hoisted by the hoisting equipment, the diamond frame 4 is hinged and the two clamps 5 are driven to move closer to each other. Then, the two clamps 5 close to each other clamp the stone and hoist it.

[0026] During the hoisting process, the screw block 8 is driven to slide inside the installation groove 7 by adjusting the screw rod 6, so that the support plate 9 drives the lifting plate 11 at the sleeve plate 10 to be at the bottom position of the stone, ensuring that the lifting plate 11 can lift the bottom of the stone. In addition, by rotating the feed screw 13, the feed screw 13 drives the movable plate 12 to slide inside the hollow sleeve plate 10, and drives the lifting plate 11 to extend outward inside the sleeve plate 10, thereby increasing the lifting range of the lifting plate 11 at the bottom of the stone.

[0027] It is worth noting that, in this structure, the rhombus frame 4 is movably hinged to drive the two clamps 5 to move closer to each other, which belongs to the prior art and will not be described in detail in this application.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
