Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically to a lifting device for automatic loading and unloading of cloth rollers. Background Technology

[0002] Liquid alkali is used in the textile industry primarily for several purposes, including stain removal and cleaning. It also plays a crucial role in bleaching textiles, accelerating pigment removal and resulting in whiter fibers. In the alkali treatment process, the fabric roll to be treated is wound onto a fabric roller. Unwinding and rewinding are required at different points in the process, necessitating the transfer of the fabric roller with the fabric and the empty roller after unwinding. Currently, there is no dedicated, highly automated lifting equipment; in practice, traditional lifting equipment is needed in conjunction with manual assistance. The high temperature in fabric processing workshops and the corrosive nature of fabric after manual contact necessitate the design of a specialized lifting device. Patent application CN110980496A discloses an automatic positioning roller lifting device and its usage method, as shown in Figure 11. In this state, the guide rod mechanism is separated from the guide sleeve, and the lifting device is suspended by a wire rope, still exhibiting some swaying. This makes it unsuitable for the precise connection and placement of the fabric roller as described above. Utility Model Content

[0003] The purpose of this invention is to provide a lifting device for automatic loading and unloading of cloth rollers, solving the problem of cloth roller lifting in the textile industry.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The lifting device for automatic loading and unloading of cloth rollers includes a fixed guide frame for mounting on a crane trolley. The fixed guide frame has a guide hole that runs vertically through the center. A lifting frame is installed in the guide hole. The lower end of the lifting frame is connected to a crossbeam. Each end of the crossbeam is provided with a hanging plate. The hanging plate is provided with a hook for engaging with the shaft section of the cloth roller. The crossbeam is provided with pulleys for the wire rope on the crane trolley to be wound around.

[0006] Furthermore, the guide hole is a rectangular guide hole, and guide wheels are provided on all four sides of the fixed guide frame in the guide hole.

[0007] Furthermore, each side of the guide hole is provided with at least two guide wheels.

[0008] Furthermore, each side of the guide hole is provided with two sets of guide wheels, each set including two guide wheels, and the two guide wheels on each side are spaced apart in the horizontal direction.

[0009] Furthermore, a guide wheel seat is fixed on the inner side of the fixed guide frame, and a guide wheel shaft is provided on the guide wheel seat. The guide wheel is installed on the guide wheel shaft, and the axial direction of the guide wheel shaft is horizontal.

[0010] Furthermore, the lifting frame is a frame structure extending in the vertical direction, including vertically arranged guide arms located at the four corners, which roll in cooperation with the guide wheels.

[0011] Furthermore, the top of the lifting frame extends outward to provide a limiting block, and the upper part of the fixed guide frame is provided with a buffer corresponding to the limiting block in the vertical direction.

[0012] Furthermore, the crane trolley is equipped with two sets of winch mechanisms. The pulleys are fixed pulleys, and the crossbeam is equipped with two pulleys spaced apart along the length of the crossbeam. One pulley is used in conjunction with a wire rope in one set of winch mechanisms. The wire rope passes around the pulley, extends upward, and connects to the fixed guide frame.

[0013] Furthermore, the bottom of the lifting frame is connected to the crossbeam via a set of flanges, which include an upper flange plate and a lower flange plate, with the bolt holes of the lower flange plate being oblong holes.

[0014] Furthermore, a first connecting plate is provided on the bottom side of both ends of the crossbeam, and a second connecting plate is provided on the upper part of the hanging plate. The first connecting plate and the second connecting plate are connected by bolts, and the first connecting plate and the second connecting plate are provided with elongated holes for the bolts to pass through.

[0015] The beneficial effects of this utility model are:

[0016] The lifting device works in conjunction with the crane in the workshop. Utilizing the coordination of the crane's trolley and hoist, the forward, backward, left, and right movement of the lifting device can be controlled. The lifting parts of the lifting device (lifting plate and hook) are sized to match the fabric roller. The hoisting mechanism on the crane trolley controls the raising and lowering of the lifting frame, thereby driving the crossbeam and lifting plate to move synchronously, completing the lifting of the fabric roller. The crane's control system enables precise movement of the lifting device, completing the lifting and lowering of the fabric roller, improving automation levels, effectively supporting intelligent workshops, reducing the number of workers responsible for lifting operations, and alleviating their labor intensity. The lifting mechanism is coordinated with a fixed guide frame and a lifting frame; the two work together without relative sway, allowing the hook of the lifting device to move vertically, thus enabling more precise control of the lifting position.

[0024] 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 skilled in the art are within the protection scope of the present utility model.

[0025] Embodiments of this utility model:

[0026] like Figures 1-6 As shown, the lifting device for automatic loading and unloading of cloth rollers includes a fixed guide frame 2 for mounting on a crane trolley 3. The fixed guide frame 2 has a guide hole that runs vertically through the center. A lifting frame 4 is installed in the guide hole. A crossbeam 51 is connected to the lower end of the lifting frame 4. A hanging plate 52 is provided at each end of the crossbeam 51. The hanging plate 52 is provided with a hook 53 for cooperating with the shaft section 71 of the cloth roller 7. After hooking the shaft section 71 of the cloth roller 7, it can be lifted.

[0027] The crane trolley 3 is equipped with two sets of winch mechanisms 31, including a wire rope 313 drum, a motor 311, and a guide pulley 312. A pulley is provided on the crossbeam 51 for the wire rope 313 on the crane trolley 3 to wind around. The pulleys are fixed pulleys 314, with two fixed pulleys 314 spaced apart along the length of the crossbeam 51. One fixed pulley 314 works in conjunction with the wire rope 313 in one set of winch mechanisms 31. The wire rope 313, winding from the wire rope 313 drum, first winds towards the guide pulley 312, passes downwards through the trolley frame of the crane trolley 3, then winds towards the fixed pulley 314, and finally extends upwards and connects to the fixed guide frame 2. The fixed end of the wire rope 313 is connected to the fixed guide frame 2. The two sets of winch mechanisms 31 are used to control the smooth lifting and lowering of the crossbeam 51.

[0028] like Figures 3-4 As shown, the guide hole is a rectangular guide hole, and the fixed guide frame 2 is provided with guide wheels 61 on all four sides of the guide hole. Each side of the guide hole has two sets of guide wheels 61 spaced vertically apart, with the two guide wheels 61 in each set on each side spaced horizontally. A guide wheel seat 62 is fixed to the inner side of the fixed guide frame 2, and a guide wheel shaft is mounted on the guide wheel seat 62. The guide wheel 61 is mounted on the guide wheel shaft, and the axis of the guide wheel shaft is horizontal. The guide wheels 61 can be directly made of roller bearings.

[0029] like Figure 5 As shown, the lifting frame 4 is a frame structure extending vertically, including vertically positioned guide arms 41 at the four corners, which roll in cooperation with the guide wheels 61. The guide arms 41 are made of rectangular tubing, and adjacent guide arms 41 are welded together using shorter, horizontally positioned rectangular tubing to form the frame structure. Each guide arm 41 has two sides that roll in cooperation with the guide wheels 61. There are 16 roller engagement points (2 groups of 8) distributed around the lifting frame 4 and the fixed guide frame 2 on all four sides, ensuring stable and reliable lifting of the lifting frame 4 within the fixed guide frame 2.

[0030] A limiting block 42 extends outward from the top of the lifting frame 4. A buffer member 21, corresponding vertically to the limiting block 42, is located on the upper part of the fixed guide frame 2. The buffer member 21 is made of polyurethane buffer column. Under normal circumstances, the descent distance of the lifting frame 4 will not cause the limiting block 42 to contact the buffer member 21. In special circumstances, such as a malfunction of the hoisting mechanism 31, this buffer member can prevent the lifting frame 4 from detaching downwards and falling to the ground, potentially injuring equipment or personnel. The limiting block 42 is formed by a rectangular tube with a cross-shaped design, and the buffer member 21 is located on each of the four sides of the top of the fixed guide frame 2.

[0031] like Figure 2 and Figure 6As shown, the bottom of the lifting frame 4 is connected to the crossbeam 51 via a set of flanges. The set of flanges includes an upper flange plate 43 and a lower flange plate 54, both of which are circular plates. The lower flange plate 54 has several bolt holes distributed circumferentially, which are oblong holes 541; the corresponding bolt holes on the upper flange plate 43 are circular holes. The upper flange plate 43 is pre-welded to the bottom of the lifting frame 4, and the lower flange plate 54 is welded to the upper side of the crossbeam 51. During assembly, bolts are used to connect the upper flange plate 43 and the lower flange plate 54. Because the bolt holes on the lower flange plate 54 are oblong holes 541, the position of the crossbeam 51 can be adjusted to better connect with the cloth roller 7 placed in the workshop. That is, the hooks 53 designed at both ends of the crossbeam 51 can be well mated with the shaft section 71 of the cloth roller 7. Figure 6 The image shows the state in which the cloth roller 7, loaded with cloth, is engaged with the lifting device.

[0032] Furthermore, the bottom sides of both ends of the crossbeam 51 are provided with first connecting plates 55, and the upper part of each hanging plate 52 is provided with a corresponding second connecting plate 56. The first connecting plate 55 and the second connecting plate 56 are connected by several bolts. The first connecting plate 55 and the second connecting plate 56 are provided with elongated holes for the bolts to pass through. The bolt holes are elongated to adjust the position of the hook 53 below the hanging plate 52. The hook 53 is a C-shaped hook. The U-shaped space between the two hanging plates 52 can be used to insert the fabric roll on the fabric roller 7. In this embodiment, the distance between the two hanging plates 52 is set to match the length of the fabric roller 7 in the user's workshop. The specifications of the fabric roller 7 in the same workshop are the same. If the user uses fabric rollers of other specifications, the dimensions of the crossbeam 51 and the hanging plate 52 can be changed.

[0033] The working principle of the lifting device for automatic loading and unloading of cloth roller 7 in this utility model is as follows:

[0034] The crane trolley 3 moves linearly on the crane trolley 1 (referred to as left-right direction), while the crane trolley 1 moves on the support beams within the workshop (referred to as front-back direction). It is a double-girder crane. The working principles of the crane's trolley and trolley are existing technologies and will not be elaborated further. By coordinating the crane's trolley and trolley, the forward-backward and left-right movement of the lifting device can be controlled. The lifting frame 4 is raised and lowered using two sets of winch mechanisms 31, thereby driving the crossbeam 51 and the hanging plate 52 to perform synchronous lifting and lowering actions, which can complete the lifting of the cloth roller 7. There are multiple placement points for the cloth roller 7 in the workshop, some with cloth and some with empty blank rollers, but the lifting action is the same: the hooks 53 at the lower end of the hanging plates 52 on both sides are used to hook and hang the shaft sections 71 on both sides of the cloth roller 7. Based on the distribution of the fabric rollers in the workshop, the coordinates of each point are calculated. Combined with the height parameters of the fabric roller axis, the crane control system can be programmed to accurately move the lifting device and complete the lifting and lowering of the fabric roller 7. This provides effective support for the intelligent workshop, reduces the number of workers in the workshop, and alleviates the labor intensity of the workers.
