Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically to a deep vertical shaft hoisting machine for carrying people and goods. Background Technology

[0002] When working in deep shafts, due to their great depth, hoists are required to lift people and goods. The core components of the hoist are the drum and the wire rope. The drum is driven by a motor to rotate, which causes the wire rope wound on it to gradually lengthen or shorten. The wire rope is connected to the cage, which in turn drives the cage to rise or fall.

[0003] To ensure the safe operation of the hoist, the drum is generally equipped with a safety section and a working section. The working section is equipped with a working wire rope, and the safety section is equipped with a safety wire rope. Both are connected to the cage. The safety wire rope is used to support the weight of the cage in place of the working wire rope when it is damaged or broken, so as to avoid safety accidents caused by the cage falling.

[0004] However, in actual use, since the working section and the safety section rotate synchronously, the safety wire rope and the working wire rope are wound or released synchronously. During the process, the safety wire rope and the working wire rope are subjected to similar tension and friction, resulting in higher wear on the safety wire rope. In the event of an accident, it may not have sufficient structural performance to support the weight of the cage.

[0005] Therefore, this application is hereby submitted. Utility Model Content

One end of the working wire rope is connected to the working section, and the other end is wound around the two working pulleys in sequence and connected to the beam frame.

[0011] Optionally, the safety section includes a low stage and a high stage, the low stage and the high stage are coaxially connected, the outer diameter of the low stage is the same as the outer diameter of the working section, and the outer diameter of the high stage is larger than the outer diameter of the low stage, so that the safety section is stepped; one end of the safety wire rope is connected to the end of the high stage away from the low stage, so that the other end is wound around the safety section in turn along the direction from the high stage to the low stage, and is wound around the two working pulleys in sequence, and connected to the beam frame.

[0012] Optionally, rope grooves are formed on the outer walls of the low stage, the high stage, and the safety section.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model provides a deep vertical shaft manned and cargo hoist. It utilizes a beam frame to provide structural support, a drive mechanism and a drum.

A cage is installed, with the working wire rope connected to the cage for lifting and lowering. Furthermore, a vertical buffer mechanism is incorporated, sliding vertically with the top of the cage. The safety wire rope is connected to the vertical buffer mechanism. During normal lifting and lowering of the cage, the working wire rope... The safety wire rope is wound differently during operation, while the working wire rope is always under tension. However, because the safety wire rope is connected to the vertical buffer mechanism, and the vertical buffer mechanism slides vertically with the top of the cage, when the safety wire rope is under tension, it inevitably causes the vertical buffer mechanism to rise a certain height relative to the cage, thus relieving the tension on the safety wire rope. This effectively reduces the wear and tear on the safety wire rope during winding and unwinding, ensuring that it always maintains sufficient structural performance. Through the interaction of these features, this deep vertical shaft personnel and cargo hoist can effectively solve the problem of synchronous wear between the safety wire rope and the working wire rope.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0021] Example 1 Please refer to Figures 1 to 5 This embodiment provides a deep vertical shaft manned and cargo hoist, including a beam frame 10, which is fixedly connected to the external environment and has a drive mechanism; secondly, a drum 20, which is rotatably mounted on the beam frame 10 and is connected to the drive mechanism, the drum 20 having a safety section 21 and a working section 22, the safety section 21 having a safety wire rope 30 wound around it, and the working section 22 having a working wire rope 31 wound around it; thirdly, a cage 40, which is used to carry people and cargo, and the working wire rope 30 is connected to the top of the cage 40; fourthly, a vertical buffer mechanism, which is located at the top of the cage 40 and slides with the cage 40 in the vertical direction, and the safety wire rope 30 is connected to the vertical buffer mechanism.

[0022] The deep vertical shaft manned and cargo hoist provided in this embodiment uses a beam frame 10 to provide structural support. A drive mechanism and a drum 20 are included. The drive mechanism rotates the drum 20. A safety section 21 and a working section 22 are provided on the drum 20, with a safety wire rope 30 and a working wire rope 31 wound around them respectively. A cage 40 is also provided, with the working wire rope 31 connected to the cage 40 to achieve the lifting and lowering of the cage 40. Furthermore, a vertical buffer mechanism is provided, which slides vertically with the top of the cage 40. The safety wire rope 30 is connected to the vertical buffer mechanism. When the cage 40 is lifting and lowering normally, the working wire rope... The working wire rope 31 and the safety wire rope 30 are wound and unwound differently. The working wire rope 31 is always under tension, while the safety wire rope 30 is connected to the vertical buffer mechanism, and the vertical buffer mechanism slides vertically with the top of the cage 40. Therefore, when the safety wire rope 30 is under tension, it will inevitably cause the vertical buffer mechanism to rise a certain height relative to the cage 40, so that the safety wire rope 30 is no longer under tension. This effectively reduces the wear of the safety wire rope 30 during winding and unwinding, ensuring that it always has sufficient structural performance. Through the cooperation of the above features, the deep vertical shaft personnel and cargo hoist can effectively solve the problem of synchronous wear of the safety wire rope 30 and the working wire rope 31.

[0023] To further explain the specific structure of the vertical buffer mechanism, the vertical buffer mechanism includes a tension cylinder 50, a support plate 51, and a buffer spring 52; the tension cylinder 50 is vertically arranged, and its bottom end passes through the top of the cage 40 and is slidably engaged; the support plate 51 is located at the bottom end of the tension cylinder 50, and the size of the support plate 51 is larger than the outer diameter of the tension cylinder 50; the buffer spring 52 is coaxially fitted outside the tension cylinder 50 and is located between the top of the cage 40 and the support plate 51; the safety wire rope 30 is connected to the top end of the tension cylinder 50.

[0024] With the above configuration, a through hole matching the size of the tension cylinder 50 is vertically opened in the top wall of the cage 40. The tension cylinder 50 is inserted into the through hole, allowing it to slide against the top of the cage 40. A support plate 51 is provided, connected to the bottom of the tension cylinder 50. The support plate 51 is larger than the outer diameter of the tension cylinder 50, i.e., larger than the diameter of the through hole, thereby limiting the relative upward stroke of the tension cylinder 50. That is, when the support plate 51 abuts against the bottom surface of the top wall of the cage 40, the tension cylinder 50 will be unable to continue upward. The vertical buffer mechanism is extended by setting a buffer spring 52 to prevent the support plate 51 from making hard contact with the top wall of the cage 40. When the safety wire rope 30 is not under tension, the support plate 51 is away from the top wall of the cage 40 and the buffer spring 52 is not compressed. When the working wire rope 31 breaks, causing the safety wire rope 30 to be under tension, the safety wire rope 30 pulls the tension cylinder 50 upward, making the support plate 51 close to the top wall of the cage 40 and compressing the buffer spring 52 until the support plate 51 abuts against the top wall of the cage 40.

[0025] To further explain the connection structure between the safety wire rope 31 and the tension cylinder 50, the top of the tension cylinder 50 is provided with a pulley seat 53. The bottom dimension of the pulley seat 53 is larger than the outer diameter of the tension cylinder 50. The pulley seat 53 is provided with a safety pulley 54. One end of the safety wire rope is connected to the safety section 21, and the other end is wound around the safety pulley 54 and connected to the beam frame 10.

[0026] By using the above settings, the bottom dimension of the pulley seat 53 is used to limit the downward stroke of the tension cylinder 50, so that the top wall of the cage 40 is located between the bottom of the pulley seat 53 and the support plate 51, and the stroke of the tension cylinder 50 is limited by both of them.

[0027] It should be noted that the safety pulley 54 has a rope groove along its circumference, and the safety wire rope 30 is matched with the rope groove.

[0028] To further explain the connection structure between the working wire rope 31 and the cage 40, a pair of working pulleys 41 are symmetrically arranged on the top of the cage 40 with the mid-plane as the reference. The two working pulleys 41 are coplanar. One end of the working wire rope 31 is connected to the working section 22, and the other end is wound around the two working pulleys 41 in sequence and connected to the beam frame 10.

[0029] To further prevent the safety wire rope 30 from being strained during normal lifting and lowering, the safety section 21 includes a low stage 211 and a high stage 212. The low stage 211 and the high stage 212 are coaxially connected. The outer diameter of the low stage 211 is the same as the outer diameter of the working section 22, and the outer diameter of the high stage 212 is larger than the outer diameter of the low stage 211, so that the safety section 21 is stepped. One end of the safety wire rope 30 is connected to the end of the high stage 212 away from the low stage 211, so that the other end is wound around the safety section 21 in turn along the direction from the high stage 212 to the low stage 211, and is wound around the two working pulleys 41 in sequence, and connected to the beam frame 10.

[0030] With the above settings, since there is a difference in outer diameter between the high stage 212 and the low stage 211, and the high stage 212 and the low stage 211 rotate synchronously, when the safety wire rope 30 wound on the high stage 212 is released, it will be released by a longer length than the working wire rope 31, thereby further avoiding the safety wire rope 30 from being strained.

[0031] To facilitate the winding of the safety wire rope 30 and the working wire rope 31, the outer walls of the lower stage 211, the higher stage 212, and the safety section 21 are all provided with rope grooves.

[0032] Preferably, to further ensure safety, the rope groove of the high stage 212 has 5 turns, of which 3 turns are safety turns and 2 turns are working turns.

[0033] It should be noted that the aforementioned safety loop refers to the safety wire rope 30 always being wound around it, while the working loop refers to the safety wire rope 30 being wound around it being able to be retracted or released.

[0034] To further explain the specific structure of the drive mechanism, the drive mechanism includes a motor 11, a reducer 12, and several brakes 13; the motor 11, the reducer 12, and the brakes 13 are all located on the beam frame 10, and the motor 11 is connected to the drum 20 through the reducer 12; at least one end of the drum 20 is coaxially provided with a brake disc 23, and at least one of the brakes 13 cooperates with the brake disc 23.

[0035] To further improve braking performance, the safety section 21 is provided with a brake disc 23 at the end away from the working section 22, and cooperates with one of the brakes 13; the motor 11 is driven to connect to a brake wheel, and at least one of the brakes 13 cooperates with the brake wheel.

[0036] It should be noted that the motor 11, reducer 12 and brake 13 mentioned above can all be any of the same products in the existing technology, as long as they can achieve their respective conventional functions.

The safety pulleys 54 of the two vertical buffer mechanisms are arranged in the same plane. One end of the safety wire rope 30 is connected to the safety section 21, and the other end is wound around the two safety pulleys 54 in sequence, and then fixedly connected to the beam frame 10. Example 3 Please refer to Figure 7 This embodiment provides a deep vertical shaft personnel and cargo hoist, which differs from Embodiment 1 only in that: The drum 20 is provided with a pair of working sections 22, and the two ends of the working wire rope 31 are respectively connected to the two working sections 22; Meanwhile, the drum 20 is also provided with a pair of safety sections 21, and the two ends of the safety wire rope 30 are respectively connected to the two safety sections 21.
