Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a quick-detachable hoist. Background Art

[0002] Mining machinery is machinery directly used for operations such as mineral mining and enrichment. Mine hoists are important equipment in mining machinery. They are mainly used to realize the lifting and transportation of materials (such as ore, gangue, etc.) in environments such as mine shafts. They are mainly composed of a drum, a brake device, a motor, a reducer, etc. The power is output by the motor, and then transmitted to the drum after deceleration and torque increase by the reducer. The rotation of the drum drives the steel wire rope wrapped around its surface to move, and the steel wire rope then pulls the lifting container up or down along the shaft to realize the lifting and transportation of materials.

[0003] In the process of realizing the present invention, the inventors found that the existing technology had the following problems: 1. In order to achieve a compact design, many mine hoists design the brake device and the drum into an integrated structure. Since the geological environment of the mine is often complex and changeable, it is easy to cause the equipment foundation to loosen, the components to be deformed, etc., and it is impossible to disassemble the individual components that need to be maintained, which increases the difficulty of disassembly and maintenance; 2. Moreover, since the base of the drum and the internal rotating equipment adopt an integrated mechanism design, when one end is disassembled, in the absence of effective support, the drum will appear to be tilted to a certain extent. If some components collide with the ground, the contact components themselves will be damaged. Utility Model Content

The inner walls of the left support plate 4 and the right support plate 5 are both fitted with brake pads 11 at both ends, and the outer walls of the left support plate 4 and the right support plate 5 are both fixedly connected with a first hydraulic cylinder 12. The power output ends of the first hydraulic cylinder 12 are fixedly connected to the brake pads 11, and the outer wall of the right support plate 5 is rotatably connected with an anti-reversal component 13.

[0025] A first external sleeve rod 601 is provided at the axis center on one side of the active turntable 6, and a second external sleeve rod 602 is provided at the axis center on the other side of the active turntable 6. The first external sleeve rod 601 passes through the left support plate 4, and the outer walls of the first external sleeve rod 601 are penetrated and threadedly connected with fastening screws 603 at both ends. The interior of the first external sleeve rod 601 is embedded with an adjusting inner rod 604, and the shaft head of the fastening screw 603 is rotatably connected to the outer wall of the adjusting inner rod 604 on the corresponding side.

[0026] The anti-reversal component 13 consists of a ratchet 1301 and a pawl 1302. The pawl 1302 is engaged with the top of the ratchet 1301. The ratchet 1301 is fixedly connected to the driven turntable 7 rotating inside the right support plate 5 through the shaft at its axis. A second hydraulic cylinder 1303 is fixedly connected to the outer wall of the right support plate 5 corresponding to the top of the pawl 1302. The power output end of the second hydraulic cylinder 1303 is integrally connected to the top of the pawl 1302 through a spring.

[0027] In this embodiment, Figure 1 and Figure 4As shown, the drive device 2 is composed of a motor and a reducer, and the power output end of the reducer is sleeved inside the adjusting inner rod 604, and the adjusting inner rod 604 is composed of two equal semicircles, and the shaft heads of the fastening screws 603 are rotatably connected to the corresponding semicircles, and one side of one set of semicircles presents an annular edge, which is slidably connected to the inner wall of the other semicircle, and the adjusting inner rod 604 forms an opening and closing structure inside the first external sleeve rod 601; the power output end at one end of the drive device 2 can be sleeved inside the first external sleeve rod 601, and at the same time The two sets of fastening screws 603 on the outside of the first external sleeve 601 can be used to adjust the opening and closing degree of the inner diameter of the adjusting inner rod 604, so that it can be accurately fixed and covered on the outside according to the size of the power output end, ensuring a tight connection between the power output end and the adjusting inner rod 604, effectively improving the convenience and accuracy of installation, and thus achieving stable and reliable power transmission to the various components inside the lifting assembly 3. When the drive device 2 or the connection part between it and the lifting assembly 3 needs to be maintained and repaired, it has obvious advantages and realizes rapid separation between components.

[0028] In this embodiment, Figure 3 、 Figure 4 and Figure 5 As shown, the driven turntable 7 and the connecting disk 8 at the corresponding end thereof have a structure consistent with the second external sleeve 602 at their axis, and the second external sleeve 602 passes through the through hole at the axis of the connecting disk 8 and is bolted to the ring-shaped structure provided on the outer wall of the through hole; different from the traditional one-piece structure, an additional connecting disk 8 is added to realize the connection between the reel 9 with the wire rope installed and the power end. The existence of this structural method does not require the entire power transmission or the connection part of related components to be disassembled as a whole when a fault occurs in the subsequent maintenance. It is only necessary to carry out targeted processing on the single side where the fault occurs. At the same time, when some parts are damaged, this modular composition can also replace the damaged parts individually. This relatively independent connection structure enables these parts to be disassembled or replaced individually without the need for complicated overall disassembly and repair as in the traditional one-piece structure.

[0029] In this embodiment, Figure 1 、 Figure 2 and Figure 3As shown, notches are provided on both sides of the reel 9 for plugging and connecting with the connecting disc 8, and the position where the connecting disc 8 and the reel 9 fit together is provided with threaded notches in a ring shape, and the middle part of the reel 9 is wound with a wire rope through the notch provided therein; the connection method between the reel 9 and the connecting disc 8 combines the convenience of plug-in connection and the stability of threaded connection, the plug-in connection facilitates quick alignment and preliminary positioning of the two components during installation, and the annularly distributed threaded notches can be further tightened by bolts, which greatly enhances the firmness of the connection and effectively prevents loosening during the operation of the hoist, and at the same time, the notch structure on the surface of the reel 9 can constrain the direction of the wire rope, avoiding the wire rope from being entangled with each other, knotting, and other chaos during the winding process, thereby ensuring that the wire rope can be smoothly retracted and released during the operation of the hoist.

[0030] In this embodiment, Figure 1 and Figure 2 As shown, pulleys are provided at both ends of the sliding base 10, and the length of the slide groove opened on the surface of the load-bearing frame 1 is greater than the overall length of the lifting assembly 3, and the surfaces of the load-bearing frame 1 and the sliding base 10 are provided with grooves for threaded bolts; when maintenance on one side is required, it is only necessary to disassemble the corresponding parts, and then use the sliding cooperation between the pulleys provided at both ends of the sliding base 10 and the slide groove opened on the surface of the load-bearing frame 1 to easily move the right support plate 5 together with the non-maintenance end from one end. When it is necessary to inspect the right support plate 5 and disassemble one end part of it, it can also be separated from the non-maintenance end with the help of the sliding structure principle. This structure not only effectively avoids the tilting phenomenon of the traditional integrated reel assembly after disassembly of the single-sided structure, but also effectively expands the required space area for maintenance work. Because in the traditional integrated reel assembly, when performing single-sided disassembly and maintenance, it is often restricted by surrounding parts and narrow space, and the operating space is cramped, which is not conducive to maintenance personnel to use maintenance tools and perform detailed inspection and maintenance operations.

[0031] In this embodiment, Figure 5 As shown, the brake pads 11 are tightly fitted to the two ends of the outer walls of the active turntable 6 and the driven turntable 7 respectively located correspondingly thereto through the first hydraulic cylinder 12; when the brake pads 11 are tightly fitted to the two ends of the outer walls of the active turntable 6 and the driven turntable 7, the rotation of the lifting assembly 3 can be extremely effectively prevented, which means that at critical moments, the lifting assembly 3 can be braked quickly and reliably, avoiding accidents such as overwinding and overspeeding caused by the continued rotation of the lifting assembly 3 that seriously endanger the safety of personnel and the integrity of equipment, thereby providing a solid safety guarantee for mining operations.

[0032] In this embodiment, Figure 6As shown, the ratchet 1301 forms a rotating structure through the active turntable 6 and the driven turntable 7, and the pawl 1302 forms a reciprocating motion; during the operation of the mine hoist, the reel 9 undertakes the important task of winding the wire rope to realize the material lifting and transportation. The existence of the ratchet 1301 and the pawl 1302 structure enables the reel 9 to always rotate in a predetermined direction, effectively avoiding the operation interruption caused by reversal, ensuring the normal operation of the hoist, and ensuring the continuity of mine production. When the lifting container needs to be lowered, the pawl 1302 is controlled by the second hydraulic cylinder 1303 to separate from the ratchet teeth on the surface of the ratchet 1301, so that unnecessary wear and damage caused by such forced operation can be avoided when reverse rotation is required.

[0033] The use method and advantages of this utility model: When the quick-detachable hoist is in use, the working process is as follows:

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, it should be noted that when the equipment is installed in the operating area, the driving device 2 and the lifting component 3 are respectively fixed to the surface of the load-bearing frame 1 by bolts, and the number of slots corresponding to the sliding base 10 and the load-bearing frame 1 can be set according to the specifications of the lifting component 3. For large-scale lifting components 3, a larger number of slots can be set to increase the contact area and load-bearing capacity of the sliding connection to ensure that the lifting component 3 can be stably supported during operation. For small-scale lifting components 3, a smaller number of slots can be set accordingly. The driving device 2 is connected to the inside of the adjusting inner rod 604 through the power output end of its reducer, and then the two sets of fastening screws 603 on the outside of the first external sleeve 601 are used to adjust the adjusting inner rod. The opening and closing degree of the inner diameter of 604 allows it to be precisely fixed and covered on the outside according to the size of the power output end, achieving a tight connection, completing the connection and installation of the drive device 2 and the left support plate 4 where the active turntable 6 is located, and an additional limiting nut can be added to the outside of the first external sleeve 601 to sleeve it on the two sets of fastening screws 603 to achieve threaded fixation, adding additional fixation, and fixing the hook of the external lifting hopper and the steel rope port on the surface of the reel 9 with the help of the connecting pin. When it is necessary to lower the lifting container, the pawl 1302 is controlled by the second hydraulic cylinder 1303 to separate from the ratchet on the surface of the ratchet 1301. When the drive device 2 rotates, the active turntable 6 drives the connecting disk 8 connected to it to rotate, thereby realizing the reel 9 and the connecting disk 8 on the other side. and the rotation of the driven turntable 7, the steel rope is in the rotating structure, and the lifting hopper is lowered. When the internal raw materials are fully loaded, the second hydraulic cylinder 1303 controls the pawl 1302 to reset and make it mesh with the surface of the ratchet 1301. During the entire lifting process, the ratchet 1301 rotates along with the rotating structure composed of the active turntable 6 and the driven turntable 7, and the pawl 1302 is always tightly attached to the ratchet teeth of the ratchet 1301, thereby smoothly passing and pushing the rotation of the ratchet 1301 and preventing it from reversing. At the same time, when an emergency occurs during the operation of the hoist, the brake pad 11 is quickly driven by the first hydraulic cylinder 12 to make it immediately fit tightly against the two ends of the outer wall of the active turntable 6 and the driven turntable 7, instantly generating a strong friction force, forcing the rotation of the lifting component 3 to stop. The bolts that fix the connecting plate 8 to the second external sleeve rod 602 can be removed to remove the connecting plate 8, and then the active turntable 6, the driven turntable 7 or the brake structures at both ends inside the left support plate 4 or the right support plate 5 can be maintained.This effectively avoids the tilting phenomenon of traditional one-piece reel components after disassembling one-side structures. It also uses bolts for fixing and disassembling, making the installation process relatively simple and easy. It not only effectively expands the space required for maintenance work, making it easier for maintenance personnel to use maintenance tools, but also improves the efficiency of maintenance loading and unloading.
