Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting machine for producing slab blanks. Background Technology

[0002] In the field of modern building decoration materials, sintered stone has become a popular product in the market due to its high strength, wear resistance, and environmental friendliness. The production process of sintered stone covers multiple stages, including raw material preparation, molding, drying, and firing. Among them, the billet lifting is a key step connecting molding and subsequent processes. With the expansion of sintered stone production scale and the growth of market demand for diversified product specifications, efficient, stable, and adaptable billet lifting equipment has become the core for ensuring production efficiency and product quality. The billet lifting machine for sintered stone production needs to be able to quickly and accurately lift the molded block sintered stone billet to a specified height so that it can be transported to the next processing station. Therefore, it is very important to develop a new type of billet lifting machine for sintered stone production.

[0003] Currently, most slab production billet lifting machines on the market adopt traditional mechanical clamping and lifting structures. The clamping part usually uses clamps with fixed spacing, which are mechanically locked by bolts or buckles. The technical principle is to manually pre-set the clamp spacing to adapt to slab billets of a specific thickness. When it is necessary to clamp billets of different thicknesses, the operator needs to stop the machine and manually adjust the clamp spacing or replace the entire clamp assembly. In the lifting process, traditional equipment mostly uses chain drive or gear rack structure, with the chain or gear driven by the motor to drive the platform with the clamps fixed to rise vertically along the guide rail. Although this structure can achieve the basic billet lifting function, it has obvious deficiencies in terms of flexibility and convenience.

[0004] However, the mechanical structure and technical principle of traditional slab production billet elevators have shortcomings, especially in terms of clamping adaptability and cleaning convenience. Due to their fixed-spacing clamping design, they cannot automatically adapt to slab billets of different thicknesses. This results in frequent machine stops to change clamps when producing products of various specifications, which not only wastes a lot of time but also increases labor costs and equipment wear and tear. Therefore, a slab production billet elevator is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a slab production billet lifting machine, which aims to improve the problem of the single clamping spacing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A slab production billet lifting machine includes an operating frame, a support frame fixedly connected inside the operating frame, a sliding component inside the support frame, a fixed box fixedly connected to the side wall of the sliding component, and a clamping component inside the fixed box.

[0008] The clamping assembly includes symmetrical clamps, the outer walls of which are set inside a fixed box. A hydraulic cylinder is fixedly connected inside the fixed box, and the output end of the hydraulic cylinder is fixedly connected to the top of the clamp. Fixed blocks are fixedly connected to both sides of the clamp. A connecting arm is rotatably connected inside the fixed box, and rocker arms are rotatably connected to both ends of the connecting arm. The other end of the rocker arm is rotatably connected to the outer wall of the fixed block. A symmetrical guide post is fixedly connected inside the fixed box, and the clamp is slidably connected to the outer wall of the guide post.

[0009] As a further description of the above technical solution:

[0010] The sliding assembly includes a lead screw, the outer wall of which is disposed inside the support frame. A motor is disposed at the top of the operating frame. The output end of the motor passes through the top of the support frame and is fixedly connected to the top of the lead screw. A set of symmetrically fixed blocks is fixedly connected inside the support frame. The outer wall of the lead screw is rotatably connected inside the set of fixed blocks.

[0011] As a further description of the above technical solution:

[0012] The lead screw is threaded to a slider, the slider is fixedly connected to a fixing plate, and the support frame is fixedly connected to symmetrical guide rails.

[0013] As a further description of the above technical solution:

[0014] The fixed plate has symmetrical guide blocks slidably connected to one side wall, and the guide blocks are slidably connected to the inside of the guide rail.

[0015] As a further description of the above technical solution:

[0016] The four corners of the fixed plate are fixedly connected to fixed columns, and the fixed columns are slidably connected to sliding columns inside the fixed columns. The outer walls of the sliding columns are slidably connected to the fixed plate and the guide block.

[0017] As a further description of the above technical solution:

[0018] A locking post is fixedly connected to the bottom of the sliding post, and the side wall of the locking post is slidably connected inside the guide block.

[0019] As a further description of the above technical solution:

[0020] The sliding column sidewall is slidably connected to a limiting plate, the outer wall of the limiting plate is rotatably connected to the inside of the first fixed plate, the sliding column sidewall is fixedly connected to a second fixed plate, and the outer wall of the second fixed plate is slidably connected to the inside of the fixed column.

[0021] As a further description of the above technical solution:

[0022] A spring is fitted on the outer wall of the sliding column. One end of the spring is fixedly connected to the side wall of the limiting plate, and the other end of the spring is fixedly connected to the two side walls of the fixing plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the output end of the hydraulic cylinder drives the top clamp to move downward, which drives the rocker arm and connecting arm connected to it to move synchronously, and then drives the rocker arm and clamp at the other end of the connecting arm to move upward until the rock slab blank is clamped, thus achieving the effect of adapting to different blank thicknesses, solving the problem of the single clamping distance of the traditional hoist, and improving the applicability of the hoist.

[0025] 2. In this utility model, when the operator rotates the sliding column clockwise to 90 degrees, the locking pin leaves the slot inside the guide block and enters the sliding groove inside the guide block. The spring rebounds, unlocking the fixed box. When the fixed box is returned after cleaning, the operator moves the sliding column into the sliding groove inside the guide block and then rotates it counterclockwise to 90 degrees. At this time, the spring is compressed, and the locking pin enters the slot inside the guide block, locking the box. This facilitates cleaning the inside of the fixed box, solves the problem of inconvenient cleaning of traditional hoists, and improves the cleaning efficiency of the hoist.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 The present invention provides an embodiment of a slab production billet lifting machine, comprising an operating frame 1, which is welded from carbon structural steel and serves as an overall support frame. A support frame 2 is fixedly connected inside the operating frame 1. The support frame 2 is also made of carbon structural steel and is used to support the sliding assembly and the fixed box 10, and to provide an installation foundation for key components such as the lead screw 4 and the guide rail 7. The support frame 2 is provided with a sliding assembly inside, and the fixed box 10 is fixedly connected to the side wall of the sliding assembly. The fixed box 10, as a key component for supporting the slab billet, is made of stainless steel plate and is provided with a clamping assembly inside the fixed box 10 for clamping the billet.

[0035] The clamping assembly includes symmetrical clamps 12, forged from alloy steel. The outer wall of the clamps 12 is located inside the fixed box 10 and works in conjunction with the hydraulic cylinder 11 and guide column 13. The hydraulic cylinder 11 is fixedly connected inside the fixed box 10. The cylinder body is made of seamless steel pipe, and the piston and piston rod surfaces are chrome-plated. The output end is driven by hydraulic oil, which is existing technology and will not be described in detail here. The output end of the hydraulic cylinder 11 is fixedly connected to the top of the top clamp 12, driving the top clamp 12 to move vertically. Fixing blocks 14, made of steel, are fixedly connected to both sides of the clamp 12. A connecting arm 16 is rotatably connected inside the fixed box 10 to the connecting rocker arm 15. Both ends of the connecting arm 16 are rotatably connected to the rocker arm 15. Both the connecting arm 16 and the rocker arm 15 are forged from steel. The other end of the rocker arm 15 is rotatably connected to the outer wall of the fixed block 14. Symmetrical guide posts 13, made of stainless steel, are fixedly connected inside the fixed box 10. The clamp 12 is slidably connected to the outer wall of the guide posts 13, and its outer wall forms a sliding fit with the guide hole inside the clamp 12, providing guidance for the up-and-down movement of the clamp 12 and ensuring the stability and accuracy of the clamping action. The moving assembly includes a lead screw 4, which is made of carbon steel through high-precision turning and thread rolling processes (existing technology, which will not be described in detail here). The outer wall of the lead screw 4 is set inside the support frame 2. A motor 3 is set on the top of the operating frame 1. The motor 3 is a three-phase asynchronous motor (existing technology, which will not be described in detail here). The output end of the motor 3 passes through the top of the support frame 2 and is fixedly connected to the top of the lead screw 4, providing stable rotational power to drive the lead screw 4 to rotate. Symmetrical upper and lower fixing blocks 5 are fixedly connected inside the support frame 2. The fixing blocks 5 are made of steel and are used to support the rotation of the lead screw 4 and reduce axial and radial rotation. The screw 4 rotates and is connected to the fixed block 5 inside. The screw 4 is threaded to a slider 6, which is made of ductile iron. The slider 6 is fixed to a fixed plate 9, which is made of steel plate, and is used to connect the slider 6 and the guide block 8. The support frame 2 is fixed to a left-right symmetrical guide rail 7, which is made of steel. The fixed plate 9 is slidably connected to a left-right symmetrical guide block 8, which is made of high-strength aluminum alloy. The guide block 8 is slidably connected to the inside of the guide rail 7, ensuring that the fixed plate 9 and the fixed box 10 slide smoothly along a straight line during the lifting process.

[0036] Reference Figure 4 and Figure 5Fixed posts 18 are fixedly connected to each of the four corners of the fixed plate 9. The fixed posts 18 are made of stainless steel and have through holes for sliding of sliding posts 17. Sliding posts 17, made of steel, are slidably connected inside the fixed posts 18. The outer wall of the sliding posts 17 is slidably connected to the fixed plate 9 and the guide block 8. A locking post 21, made of alloy steel, is fixedly connected to the bottom of the sliding posts 17. The locking post 21 engages with a slot inside the guide block 8 to lock the fixed box 10. The side wall of the locking post 21 is slidably connected to the guide block 8. A limit plate 20 is slidably connected to the side wall of the sliding posts 17. The positioning plate 20 is made of steel plate. The outer wall of the limiting plate 20 is rotatably connected to the inside of the first fixing plate 9 to limit the axial displacement of the sliding column 17. The side wall of the sliding column 17 is fixedly connected to the second fixing plate 22, which is also made of steel plate. The outer wall of the second fixing plate 22 is slidably connected to the inside of the fixing column 18 to fix the spring 19. The outer wall of the sliding column 17 is fitted with the spring 19. One end of the spring 19 is fixedly connected to the side wall of the limiting plate 20, and the other end of the spring 19 is fixedly connected to the side wall of the second fixing plate 22. Through compression and rebound, the elastic force required for unlocking and locking is provided, so as to realize the quick assembly and disassembly of the fixing box 10.

[0037] Working principle: When using the slab production billet elevator, the worker first places the formed block slab billet between the clamps 12. Then, the output end of the hydraulic cylinder 11 drives the top clamp 12 to move downward, which in turn drives the rocker arm 15 connected to it to move downward. The movement of the rocker arm 15 drives the connecting arm 16 to move downward as well, which in turn drives the rocker arm 15 and the clamp 12 at the other end of the connecting arm 16 to move upward until the slab billet is clamped, thus achieving the effect of adapting to different billet thicknesses.

[0038] Subsequently, the output end of motor 3 drives the lead screw 4 to rotate clockwise. The output end of lead screw 4 then drives the guide block 8 and the fixed box 10 to slide upward within the guide rail 7, completing the lifting of the rock slab blank. When it is necessary to clean the fixed box 10, the operator first rotates the sliding column 17 clockwise to 90 degrees. At this time, the locking column 21 leaves the slot inside the guide block 8 and enters the sliding groove inside the guide block 8. The spring 19 rebounds, completing the unlocking of the fixed plate 9 and the fixed box 10, facilitating the next step of cleaning. When the fixed box 10 is put back after cleaning, the operator inserts the sliding column 17 into the sliding groove inside the guide block 8 and then rotates the sliding column 17 counterclockwise to 90 degrees. At this time, the spring 19 is compressed, and the locking column 21 enters the slot inside the guide block 8, completing the locking of the fixed plate 9 and the fixed box 10, achieving the effect of facilitating the cleaning of the inside of the fixed box 10.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
