Description

Technical Field

[0001] The utility model relates to the technical field of material transportation equipment, in particular to an upper steamer hoist. Background Art

[0002] Baijiu is a distilled liquor unique to China. Its unique production process gives it a unique flavor. Its aroma components are extremely complex, with a wide variety of components and a wide range of contents, making it the best distilled liquor in the world. Solid-state liquor refers to liquor produced in a solid matrix form during the main processes of cooking, saccharification, fermentation, and distillation.

[0003] In the brewing process, most of the brewing processes require the hopper to be transported vertically, such as the steaming process, the mixing process, etc. At present, the vertical transportation of the hopper is mainly completed by a crane installed in the workshop. The positioning accuracy of the crane is poor and it needs to be manually unhooked, so there are certain safety hazards.

[0004] The applicant is committed to the research of elevators and applied for a publication number CN219044782U in 2022. A winch elevator comprises a frame, a car movably arranged in the frame and a first power mechanism for driving the car to rise and fall in the frame; the car comprises a car support, on which a first chain conveyor for horizontally conveying a bucket in and out of the car is provided; the first power mechanism comprises a winch arranged on the outside of the frame, a first pulley block and a seventh pulley block are arranged at a certain distance on one side of the top of the frame, a fourth pulley block is arranged on the other side of the top of the frame, a second pulley and a sixth pulley are arranged at a certain distance on one side of the top of the car support, and a third pulley and a fifth pulley are arranged on the other side of the top of the car support; it can also complete the reversing transportation of the bucket in four horizontal directions.

[0005] During the subsequent actual use, the following problems were found: Since the guide mechanism uses two rollers and a T-shaped guide rail, during the frequent lifting and lowering of the car, there is constant friction between the rollers and the T-shaped guide rail, which causes the roller temperature to rise. The rollers are rubber wheels, so the rollers will debond after being heated, causing the distance between the rollers and the T-shaped guide rail to increase, causing the car to shake during the lifting process, and the stability to deteriorate. In addition, noise is generated during the shaking process, and the T-shaped guide rail will be hit, causing the T-shaped guide rail to bend and be damaged. Utility Model Content

Therefore, they cannot be understood as limitations on the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The following is combined with Figures 1 to 6 The utility model is further described.

[0036] Embodiment 1

[0037] In view of the technical problems existing in the background technology, the utility model provides an upper steamer position lifting machine.

[0038] The specific technical solution includes a frame 1 and a car 2 movably arranged in the frame 1, the car 2 is used to transport the hopper 5 in the vertical direction, and the frame 1 is provided with a first power assembly 3 that drives the car 2 to rise and fall in the frame 1, which can be referred to Figure 1 .

[0039] The first power assembly 3 includes a hoist 301 disposed outside the frame 1, a first pulley block 302 disposed on the top of the frame 1, and a second pulley block 303 disposed on the top of the car 2. The hoist 301 is connected to the first pulley block 302 and the second pulley block 303 in sequence through a steel wire rope. Figure 1 , Figure 2 and Figure 6 The first pulley block 302 includes ten pulleys, and the second pulley block 303 includes four second pulleys 304. One end of the wire rope is led out from the hoist 301, and then returns to the hoist 301 after passing through the first pulley block 302 and the second pulley block 303, which is equivalent to using a double-line combination. The two strands of wire ropes are synchronously extended and retracted, thereby driving the elevator car to rise and fall smoothly in the frame. The present utility model does not improve the first power assembly 3, and continues to use the original power arrangement, so its principle is not repeated here.

[0040] In addition, in order to ensure that the car 2 is lifted and lowered smoothly in the frame 1, a guide assembly 4 is further provided on the frame 1 in this embodiment, and the guide assembly 4 is used to guide the car 2 during the lifting process.

[0041] The above structure is the same as the winch hoist structure of the prior art. In order to solve the technical problems of short roller service life and high maintenance cost of the guide mechanism of the winch hoist of the prior art, the present embodiment makes the following improvements to the guide assembly:

[0042] The guide assembly 4 includes a T-shaped guide rail 401 vertically arranged on the frame 1, a guide shoe 402 is arranged on the car 2, a slot 403 is arranged on the guide shoe 402, the slot 403 is clearance-matched with the T-shaped guide rail 401, and the T-shaped guide rail 401 is movably arranged in the slot 403, which can be referred to Figure 5 During the lifting process of the car 2, the guide shoe 402 on the car 2 will slide along the T-shaped guide rail 401, thereby guiding the car 2 during the lifting process, ensuring the smooth lifting of the car 2 in the frame 1. It can be seen that compared with the existing roller matching method, the utility model adopts the matching method of the guide shoe and the T-shaped guide rail, which can effectively resist the problem of component deformation or roller debonding caused by frictional heat generation, and the guide shoe guidance method has better limiting and guiding effects.

[0043] In order to make the contact between the T-shaped guide rail 401 and the slot 403 smoother and reduce the wear of the guide shoe 402, a wear-resistant pad (not shown in the figure) is further provided in the slot 403 in this embodiment, and the wear-resistant pad is made of engineering wear-resistant plastic.

[0044] In this embodiment, an anti-falling device 102 is also provided on the car 2, which can be referred to Figure 6 . Under normal conditions, the car is raised and lowered at a uniform speed. When the first power component fails or fails, the car will fall rapidly. At this time, the anti-fall device acts as a brake to control the car to stop running, thereby preventing and protecting it. The anti-fall device includes a speed limiter, a speed limiter rope, a linkage mechanism and a safety clamp. The anti-fall device is a mature device in the prior art and is mostly used for preventing elevators from falling. Its specific principle will not be repeated here. The anti-fall device in the prior art winch hoist is used as a reference for this application.

[0045] In order to prevent the components in the rack 1 from accidentally falling and injuring outsiders, and also to prevent the staff from approaching the rack for protection, a protective net (not shown in the figure) is further provided on the outside of the rack 1 in this embodiment.

[0046] In order to realize horizontal conveying and horizontal reversing conveying of the hopper, the car 2 in this embodiment includes a car support 201, on which a first chain conveyor 202 for horizontally conveying the hopper 5 in and out of the car 2 and a second chain conveyor 203 for horizontally reversing conveying the hopper 5 are arranged. The second chain conveyor 203 is embedded in the first chain conveyor 202, and the first chain conveyor 202 and the second chain conveyor 203 are perpendicular to each other. Figure 6 In particular, the second chain conveyor 203 is provided with a second oil cylinder 205 and a second guide plate 204, the fixed end of the second oil cylinder 205 is connected to the second chain conveyor 203, and the movable end of the second oil cylinder 205 is connected to the second guide plate 204, which can be referred to Figure 3 The present invention does not improve the structure of the first chain conveyor 202 and the second chain conveyor 203, and continues to use the original arrangement, so the principle is not repeated here. The improvement is mainly in the second oil cylinder 205. The prior art winch hoist uses a cylinder to drive the second guide plate to rise and fall, but the cylinder has a weak support force and a high failure rate. Therefore, this embodiment uses an oil cylinder to replace the prior art cylinder.

[0047] The frame 1 in this embodiment includes four columns 101 arranged in a square shape. The positions of the columns corresponding to the car support 201 are provided with V-shaped rollers 206 which are rollingly connected with the columns 101. The V-shaped rollers 206 are connected with the car support 201 through disc springs 207. Figure 5 . During the lifting and lowering of the car, the V-shaped roller and the column are rollingly connected, and the two play a guiding and limiting role, preventing the car from swaying during the lifting process, and ensuring the smooth lifting and lowering of the car. The V-shaped roller can not only play a guiding and limiting role in the vertical direction, but also play a limiting role in the horizontal direction, preventing the car from swaying in the horizontal direction. In addition, the disc spring enables a flexible connection between the V-shaped roller and the car support, so that the V-shaped roller has a certain independent variable, which plays a buffering role, and can avoid damage to the V-shaped roller due to excessive torque between the car support and the frame, thereby protecting the equipment. This design also continues to use the design method of the prior art winch hoist, and the utility model does not make an improvement thereon.

[0048] Embodiment 2

[0049] The T-shaped guide rail of the prior art winch hoist is connected to the frame by welding. Due to the large longitudinal height and span of the T-shaped guide rail, as well as the manufacturing and installation errors of the T-shaped guide rail, it is impossible to ensure that the T-shaped guide rail is installed vertically on the frame, resulting in a slight bending of part of the T-shaped guide rail, which causes shaking during the lifting of the car.

[0050] Therefore, in order to solve the above technical problems, based on the first embodiment, the present embodiment improves the connection method between the T-shaped guide rail and the frame as follows: the T-shaped guide rail 401 of the present embodiment is connected to the frame 1 by bolts, and the bolt holes connecting the two are long holes, so the position of the T-shaped guide rail can be appropriately adjusted in the horizontal direction, and after the position is adjusted, it can be tightened by bolts, which can effectively ensure the verticality of the T-shaped guide rail and ensure the stability of the car during the lifting process in the frame.

[0051] Embodiment 3

[0052] During the descent of the car 2, the following situation may occur: when the car 2 is temporarily stuck in the frame 1 due to reasons such as incorrect position, no relevant components can detect that the car 2 is stuck in the frame 1, and the hoist 301 will continue to release the wire rope, so the wire rope released by the hoist 301 will be stacked on the top of the car. After the car is smooth, the car will produce a free fall operation, which will then hit the frame and damage the hoist. Although the anti-falling device of the first embodiment has an anti-falling function, the response time of the anti-falling device is long, and it cannot respond in time to the car being temporarily stuck in the frame.

[0053] Therefore, in order to solve the above technical problems, based on the first embodiment, a weight sensor 305 is provided on the pulley hole of the second pulley 304 in this embodiment, which can be referred to Figure 6 . The weight sensor, connecting cable, microcomputer host, etc. constitute the overload limiter system. The weight sensor 305 can sense the load of the car in real time. Under normal conditions, the wire rope tightens the car, and the system senses the load of the car, indicating normal; when the car is temporarily stuck in the frame, the winch will continue to release the wire rope. Since the wire rope is not stressed, the system cannot sense the load of the car at this time, indicating abnormality. The system immediately sends a designated control winch operation, thereby effectively preventing the car from free falling and avoiding collision between the car and the frame, and also protecting the winch.

[0054] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific implementation methods of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
