Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting device technology, and in particular to a liner plate disassembly and hoisting device. Background Technology
[0002] As a key piece of equipment in the field of ore crushing, rod mills are widely used in many industries such as artificial sand and gravel, mineral processing, chemical industry, power plants and steel slag crushing. The weight of the liners in rod mills is usually 50-90kg, and in some cases even up to 100kg. The liners need to be disassembled and replaced regularly.
[0003] Currently, due to the excessive weight of the liners, manual handling is not only extremely labor-intensive but also prone to accidents such as crushing and bumping. Although the overhead crane in the workshop can assist in bearing the weight, it is limited by the narrow internal space of the rod mill cylinder, resulting in extremely poor operational flexibility and difficulty in precise positioning. At the same time, the size and specifications of different models of liners vary greatly, and there is a lack of universally compatible operating tools, leading to low disassembly and assembly efficiency.
[0004] Therefore, there is an urgent need for a liner plate disassembly and hoisting device to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a liner plate disassembly and hoisting device to solve the problems of difficult, dangerous and inefficient liner plate disassembly and assembly in rod mills, simplify the liner plate disassembly and assembly process, improve operational safety and efficiency, and reduce labor intensity.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A liner removal and hoisting device is used for removing and hoisting liners inside a rod mill. The rod mill includes a rotatable hollow cylinder with an opening at one end. The axial direction of the cylinder is horizontal. The liner removal and hoisting device includes:
[0008] The base frame, crossbeam, and displacement assembly are provided. The base frame is disposed outside the opening and has a pre-reserved gap with the cylinder. The crossbeam is fixed on the base frame and extends into the cylinder from the opening in the horizontal direction. The displacement assembly includes a track and a slider. The track is disposed on the crossbeam and extends in the horizontal direction. The slider is slidably disposed on the track.
[0009] The lifting assembly, hook, and clamping assembly are provided. The lifting assembly is mounted on the sliding member, and the hook is mounted on the output end of the lifting assembly. The hook is detachably connected to the clamping assembly, which is configured to clamp the liner. The lifting assembly can drive the hook to rise or fall vertically to drive the liner to move synchronously.
[0010] As an optional solution for a liner removal and hoisting device, the clamping assembly includes a first clamping arm, a second clamping arm, a pin, and a connecting rope. The first clamping arm and the second clamping arm are arranged crosswise and rotatably connected by the pin. The first end of the connecting rope is connected to the operating end of the first clamping arm facing away from the liner, and the second end of the connecting rope is connected to the operating end of the second clamping arm facing away from the liner. When the hook hooks the connecting rope and applies force upward in the vertical direction, it can drive the clamping ends of the first clamping arm and the second clamping arm facing the liner to rotate and move closer to each other to clamp the liner of different sizes.
[0011] As an optional solution for the liner removal and hoisting device, both the clamping end of the first clamping arm and the clamping end of the second clamping arm are provided with positioning grooves. The positioning grooves of the first clamping arm and the second clamping arm are arranged opposite to each other, which can jointly accommodate part of the liner and restrict the position of the liner.
[0012] As an optional solution for the liner removal and hoisting device, anti-slip pads are provided in the positioning groove of the first clamping arm and the positioning groove of the second clamping arm.
[0013] As an optional solution for the liner removal and hoisting device, the clamping assembly also includes an elastic element, the two ends of which are connected to the first clamping arm and the second clamping arm respectively. When the hook hooks the connecting rope, the elastic element deforms and stores energy; when the hook releases the connecting rope, the elastic element releases elastic potential energy, driving the first clamping arm and the second clamping arm to return to their initial positions.
[0014] As an optional solution for the liner removal and hoisting device, the connecting rope is a metal wire rope.
[0015] As an optional solution for the liner removal and hoisting device, the displacement assembly also includes a drive motor, the output of which is connected to the sliding member in a transmission connection, and the drive motor is capable of driving the sliding member to slide along the track.
[0016] As an optional solution for the liner removal and hoisting device, the lifting assembly is an electric hoist.
[0017] As an optional solution for the liner removal and hoisting device, the base frame is height adjustable.
[0018] As an optional solution for the liner removal and hoisting device, the liner removal and hoisting device also includes casters, which are located at the bottom of the base frame, can support the base frame, can roll to drive the base frame to move, and can be locked to fix the base frame.
[0019] Beneficial effects:
[0020] This invention provides a liner removal and lifting device. When removing liners from a rod mill, a gap is left between the base frame and the cylinder. The cylinder is rotated to position the liner to be operated below the crossbeam. The clamping assembly holds the liner and connects to a hook. The lifting assembly drives the hook to lift the liner vertically. After adjusting to a suitable height, the sliding member moves horizontally along the track on the crossbeam, moving the liner out of the cylinder through the opening. When installing liners in the rod mill, the reverse operation is used to send the liner into the cylinder for installation. This invention solves the problems of difficult, dangerous, and inefficient liner removal and installation in rod mills, greatly simplifying the liner removal and installation process, improving operational safety and efficiency, and reducing labor intensity.

[0031] This embodiment discloses a liner plate disassembly and hoisting device, such as... Figures 1-3As shown, the liner removal and hoisting device is used to remove and hoist the liner 200 inside a rod mill. The rod mill includes a rotatable hollow cylinder 100 with an opening 101 at one end. The axial direction of the cylinder 100 is horizontal. The liner removal and hoisting device includes a base frame 11, a crossbeam 12, a displacement assembly 2, a lifting assembly 3, a hook 4, and a clamping assembly 5. The base frame 11 is located outside the opening 101 and has a pre-reserved gap with the cylinder 100. The crossbeam 12 is fixed to the base frame 11 and extends horizontally from the opening 101 into the cylinder. Inside the cylinder 100; the displacement component 2 includes a track 21 and a slider 22. The track 21 is mounted on the crossbeam 12 and extends horizontally. The slider 22 is slidably mounted on the track 21. The lifting component 3, hook 4, and clamping component 5 are also included. The lifting component 3 is mounted on the slider 22. The hook 4 is mounted on the output end of the lifting component 3. The hook 4 is detachably connected to the clamping component 5. The clamping component 5 is used to clamp the liner 200. The lifting component 3 can drive the hook 4 to rise or fall vertically to drive the liner 200 to move synchronously.
[0032] When disassembling the liner 200 inside the rod mill using this liner removal and lifting device, a gap is reserved between the base frame 11 and the cylinder 100. The cylinder 100 is rotated to position the liner 200 to be operated inside the cylinder 100 below the crossbeam 12. The clamping assembly 5 clamps the liner 200 and connects it to the hook 4. The lifting assembly 3 drives the hook 4 to lift the liner 200 vertically. After adjusting to a suitable height, the sliding member 22 moves horizontally along the track 21 on the crossbeam 12, moving the liner 200 out of the cylinder 100 through the opening 101. When installing the liner 200 inside the rod mill, the reverse operation is performed to send the liner 200 into the cylinder 100 for installation. This solves the problems of difficult, dangerous, and inefficient disassembly and assembly of the liner 200 in the rod mill, greatly simplifying the liner 200 disassembly and assembly process, improving operational safety and efficiency, and reducing labor intensity.
[0033] It is worth noting that the operator can work inside the cylinder 100. After clamping and fixing the liner 200 to be operated by the clamping assembly 5, the operator can connect the clamping assembly 5 to the hook 4 and manually push the sliding member 22 to move horizontally along the track 21 on the crossbeam 12 to move the liner 200 out of the cylinder 100 through the opening 101.
[0034] In addition, the number of base frames 11 in the liner removal and hoisting device can be two. Both ends of the cylinder 100 are provided with openings 101. The two base frames 11 are symmetrically arranged on the outside of the two openings 101, and both are reserved with a gap from the cylinder 100 to avoid affecting the normal rotation of the cylinder 100. The two ends of the crossbeam 12 are fixedly connected to the two base frames 11 respectively to prevent the crossbeam 12 from shifting and injuring the operators inside the cylinder 100, ensuring the stability of the crossbeam 12, and ensuring that the process of the liner 200 entering or leaving the cylinder 100 is reliable.
[0035] like Figure 3 As shown, the clamping assembly 5 includes a first clamping arm 51, a second clamping arm 52, a pin 53, and a connecting rope 54. The first clamping arm 51 and the second clamping arm 52 are arranged crosswise and rotatably connected by the pin 53. The first end of the connecting rope 54 is connected to the operating end of the first clamping arm 51 that is away from the liner 200, and the second end of the connecting rope 54 is connected to the operating end of the second clamping arm 52 that is away from the liner 200. When the hook 4 hooks the connecting rope 54 and applies force upward in the vertical direction, it can drive the clamping ends of the first clamping arm 51 and the second clamping arm 52 that are towards the liner 200 to rotate and move closer to each other, so as to clamp liners 200 of different sizes. The clamping assembly 5 is connected by the first clamping arm 51 and the second clamping arm 52 through cross-rotation. With the force applied by the connecting rope 54 and the hook 4, the clamping ends of the first clamping arm 51 and the second clamping arm 52 can flexibly open and close to adjust the clamping distance, which can firmly clamp the liner 200 of different sizes. It is easy to operate and highly adaptable, improving the clamping reliability and efficiency when assembling and disassembling the liner 200.
[0036] like Figure 3 As shown, both the clamping ends of the first clamping arm 51 and the second clamping arm 52 are provided with positioning grooves 50. The positioning grooves 50 of the first clamping arm 51 and the second clamping arm 52 are arranged opposite to each other, which can jointly accommodate part of the liner 200 and restrict the position of the liner 200. The clamping ends of the first clamping arm 51 and the second clamping arm 52 are provided with opposing positioning grooves 50, which can jointly accommodate part of the liner 200, effectively restrict the position of the liner 200, prevent the liner 200 from shaking or shifting during clamping or transfer, enhance clamping stability, and ensure that the assembly and disassembly of the liner 200 are more accurate and safer.
[0037] In other embodiments, the liner 200 is provided with two positioning holes. The first clamping arm 51 and the second clamping arm 52 can be opened and closed to adapt to the distance between the two positioning holes, so that the clamping ends of the first clamping arm 51 and the second clamping arm 52 respectively extend into the corresponding positioning holes of the liner 200. The first end of the connecting rope 54 is connected to the operating end of the first clamping arm 51 away from the liner 200, and the second end of the connecting rope 54 is connected to the operating end of the second clamping arm 52 away from the liner 200. When the hook 4 hooks the connecting rope 54 and applies force vertically upward, it can drive the clamping ends of the first clamping arm 51 and the second clamping arm 52 to rotate and move closer to each other, so that the clamping ends of the first clamping arm 51 and the second clamping arm 52 respectively abut against the hole wall of the corresponding positioning hole, thereby clamping the liner 200. This structure adapts to positioning holes with different spacing on the liner 200 and completes clamping simultaneously by applying force, improving the convenience of operation and the reliability of clamping.
[0038] In this embodiment, anti-slip pads are provided in the positioning groove 50 of the first clamping arm 51 and the positioning groove 50 of the second clamping arm 52. The anti-slip pads can increase the friction between the positioning groove 50 and the liner 200, preventing the liner 200 from slipping and falling off during clamping. Especially during lifting or transferring, they can enhance clamping stability, reduce the risk of damage or falling of the liner 200, and improve operational safety.
[0039] Alternatively, the anti-slip mat can be a rubber mat, which has good elasticity and strong wear resistance; the anti-slip mat can also be a silicone mat, which is resistant to high and low temperatures and has an outstanding anti-slip effect. The type of anti-slip mat is not specifically limited here.
[0040] In this embodiment, the clamping assembly 5 also includes an elastic element (not shown). The two ends of the elastic element are connected to the first clamping arm 51 and the second clamping arm 52, respectively. When the hook 4 hooks the connecting rope 54, the elastic element deforms and stores energy. When the hook 4 releases the connecting rope 54, the elastic element releases its elastic potential energy, driving the first clamping arm 51 and the second clamping arm 52 back to their initial positions. The elastic element of the clamping assembly 5 connects the first clamping arm 51 and the second clamping arm 52. When the hook 4 hooks the connecting rope 54, the first clamping arm 51 and the second clamping arm 52 rotate, stretching or compressing the elastic element to store energy through deformation. When the hook 4 releases the connecting rope 54, the elastic element releases its elastic potential energy and drives the first clamping arm 51 and the second clamping arm 52 to rotate and reset. This eliminates the need for manual adjustment of the initial state, simplifies the operation process, improves the efficiency of disassembling and assembling the liner 200, and enhances the ease of use of the clamping assembly 5.
[0041] In some embodiments, the two ends of the elastic element are connected to the operating ends of the first clamping arm 51 and the second clamping arm 52, respectively. When the hook 4 applies force, the operating ends of the first clamping arm 51 and the second clamping arm 52 rotate around the pin 53 and move closer to each other to compress the elastic element. After the hook 4 is released, the elastic element releases its elastic potential energy, causing the operating ends of the first clamping arm 51 and the second clamping arm 52 to rotate around the pin 53 and move away from each other, returning to their initial positions. The structure in which the two ends of the elastic element are connected to the clamping ends of the first clamping arm 51 and the second clamping arm 52, respectively, is similar and will not be described in detail here.
[0042] In other embodiments, the two ends of the elastic element are connected to the operating end of the first clamping arm 51 and the clamping end of the second clamping arm 52, respectively. When the hook 4 applies force, the operating end of the first clamping arm 51 and the clamping end of the second clamping arm 52 rotate around the pin 53 and move away from each other to stretch the elastic element. After the hook 4 is released, the elastic element releases its elastic potential energy, causing the operating end of the first clamping arm 51 and the clamping end of the second clamping arm 52 to rotate around the pin 53 and move closer to each other, returning to their initial positions. Similarly, the two ends of the elastic element are connected to the operating end of the second clamping arm 52 and the clamping end of the first clamping arm 51, respectively, which will not be elaborated further here.
[0043] Alternatively, the elastic element can be a spring, an elastic rope, or a rubber strip, without specific limitations.
[0044] In this embodiment, the connecting rope 54 is a metal wire rope. The metal wire rope has high strength and wear resistance, and can stably transmit the tension of the hook 4, ensuring that the first clamping arm 51 and the second clamping arm 52 can reliably clamp the liner 200. Moreover, the metal wire rope is not easy to break or deform, which is suitable for the force requirements when the liner 200 is disassembled and assembled, and improves the durability and safety of the clamping assembly 5.
[0045] In this embodiment, the metal wire rope is a stainless steel wire rope. Stainless steel wire rope is corrosion resistant and has high strength. It can stably transmit the tension of the hook 4, ensuring that the first clamping arm 51 and the second clamping arm 52 can reliably clamp the liner 200. It is not easy to rust or break, which improves the durability of the connecting rope 54 and ensures that the clamping assembly 5 works stably for a long time.
[0046] In other embodiments, the metal wire rope may also be galvanized steel wire rope or copper wire rope. No specific limitation is made here. In still some embodiments, the connecting rope 54 may also be nylon rope or polyester rope, no specific limitation is made here.
[0047] In this embodiment, the displacement component 2 also includes a drive motor. The output end of the drive motor is connected to the sliding member 22 via a transmission connection. The drive motor can drive the sliding member 22 to slide along the track 21. The drive motor can automatically drive the sliding member 22 to slide along the track 21, replacing manual operation, accurately controlling the sliding position and speed, improving the transfer efficiency of the liner 200, reducing manpower input, reducing operational errors, and adapting to frequent disassembly and assembly requirements.
[0048] In this embodiment, the lifting component 3 is an electric hoist. The electric hoist can stably drive the hook 4 to lift the liner 200. The lifting speed and height are controllable, the operation is precise and labor-saving, it replaces manual lifting, reduces labor intensity, and is suitable for the lifting needs of liners 200 of different weights, improving assembly and disassembly efficiency and safety. The electric hoist is existing technology and will not be described in detail here.
[0049] Currently, the weight of the liner plate 200 in a rod mill is typically 50-90 kg, and in some scenarios even reaches 100 kg. In this embodiment, an electric hoist with a rated load capacity of 200 kg is selected to ensure stable and safe lifting of the liner plate 200, guaranteeing reliable operation and improving work efficiency. In other embodiments, the rated load capacity of the electric hoist is 180 kg, 190 kg, 210 kg, 220 kg, etc., and no specific limitation is made here.
[0050] In other embodiments, the lifting component 3 is a cylinder, and the piston rod in the cylinder can reciprocate vertically relative to the cylinder. The piston rod is connected to the hook 4, and the movement of the piston rod can drive the hook 4 to move vertically, thereby causing the liner 200 to rise and fall synchronously in the vertical direction. The cylinder has a rapid response and stable power, can accurately control the lifting height of the liner 200, has a compact structure and is easy to maintain, and improves the flexibility and efficiency of liner 200 assembly and disassembly.
[0051] In some embodiments, the lifting assembly 3 is a hydraulic cylinder. The hydraulic rod in the hydraulic cylinder can reciprocate vertically relative to the hydraulic cylinder. The hydraulic rod is connected to the hook 4. The movement of the hydraulic rod can drive the hook 4 to move vertically, thereby causing the liner 200 to rise and fall synchronously in the vertical direction. The hydraulic cylinder has a rapid response and stable power, can accurately control the lifting height of the liner 200, has a compact structure and is easy to maintain, and improves the flexibility and efficiency of liner 200 assembly and disassembly.
[0052] like Figure 2 As shown, the height of the base frame 11 is adjustable to adapt to the height of the opening 101 of the cylinder 100 of different sizes, ensuring that the crossbeam 12 extends precisely to the appropriate position inside the cylinder 100 without affecting the normal rotation of the cylinder 100. This facilitates the coordinated operation of the displacement component 2 and the lifting component 3, improves the adaptability of the liner plate disassembly and hoisting device, and makes the disassembly and assembly of the liner plate 200 more flexible and efficient.
[0053] Specifically, the base frame 11 includes a first rod 111, a second rod 112, and a third rod 113. The first rod 111 and the second rod 112 extend vertically, and the two ends of the third rod 113 are connected to the first rod 111 and the second rod 112 respectively, forming a U-shaped structure. The crossbeam 12 is fixed on the third rod 113 and is set perpendicular to the third rod 113. The heights of the first rod 111 and the second rod 112 are adjustable. The first rod 111 includes a first inner sleeve and a first outer sleeve. The first inner sleeve can extend and retract within the first outer sleeve and is locked by fasteners. The second rod 112 includes a second inner sleeve and a second outer sleeve. The second inner sleeve can extend and retract within the second outer sleeve and is locked by fasteners, so that the crossbeam 12 can adapt to the opening 101 height of cylinders 100 with different diameters, ensuring that the crossbeam 12 is in the optimal working position and improving the versatility of the liner plate disassembly and hoisting device. In addition, the height is highly stable after locking, ensuring the safety and accuracy of the liner plate 200 during disassembly and assembly.
[0054] In this embodiment, the liner removal and hoisting device also includes casters (not shown). The casters are located at the bottom of the base frame 11, capable of supporting the base frame 11 and rolling to move the base frame 11. The casters can also be locked to fix the base frame 11. On one hand, the casters at the bottom of the base frame 11 can support and move the base frame 11, facilitating the flexible adjustment of the liner removal and hoisting device to a suitable position next to the cylinder 100, improving ease of movement. On the other hand, the casters can be locked to fix the base frame 11, preventing the base frame 11 from shaking during the removal and installation of the liner 200, ensuring operational stability and safety.
[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
