Description

Technical Field

[0001] This utility model belongs to the technical field of mine skip hoists, specifically a mine skip hoist. Background Technology

[0002] In mining operations, the mine skip hoist, as a core piece of equipment connecting the underground mining face with the surface transportation system, undertakes the vertical transportation of materials such as ore and gangue. Its operational stability, safety, and transportation efficiency directly determine the overall production efficiency of the mine. Currently, mainstream mine skip hoists mainly consist of the skip body, hoisting wire rope, drive unit, sheave, braking system, and electrical control system. The working process involves the drive unit driving the wire rope to pull the skip in reciprocating motion within the shaft, realizing the transfer of materials from underground to the surface. However, existing mine skip hoists suffer from a key technical deficiency in practical applications: they lack real-time weighing capabilities for the material being hoisted within the skip. In actual mine production, underground loading operations often rely on manual experience to control the loading volume, or only make rough estimates based on the skip's volume, making it impossible to accurately obtain the actual weight of the material. This lack of weighing capabilities directly leads to the following series of problems: First, the safety risks are significant. When the actual weight of the material in the skip exceeds the design rated load of the hoist, it will cause overload operation problems: on the one hand, overload will significantly increase the tension of the hoisting wire rope, leading to accelerated fatigue damage of the wire rope, and in severe cases, wire rope breakage, causing a major safety accident of skip falling; on the other hand, overload will increase the load on the drive device and braking system, causing the drive motor to overheat and the braking distance of the braking system to be extended, which not only reduces the service life of the equipment, but may also cause the hoist to go out of control due to brake failure, threatening the lives of underground workers and the safety of mine property.

[0003] Therefore, a mining skip hoist is proposed to address the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a mining skip hoist that can weigh materials during the hoisting process, preventing overloading and excessive weight, which would significantly increase the tension of the hoisting wire rope, accelerate wire rope fatigue damage, and in severe cases, cause wire rope breakage and a major safety accident resulting in the skip falling. This effectively improves the safety of the hoist.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mine skip hoist, including a base plate; The surface of the base plate is equipped with a weighing and detection assembly, which includes a hoist body installed on the surface of the base plate, a skip body set at the bottom of the base plate, and a sleeve, extrusion plate, connecting plate, weight detection module, hanging rope, hook, lifting steel rope, and slide bar for weighing. The surface of the sleeve is equipped with a disassembly and maintenance assembly, which includes a threaded rod at the top of the sleeve and a threaded sleeve installed at one end of the lifting steel rope.

[0007] Preferably, a return spring is sleeved on the surface of the slide rod, one end of the return spring is connected to the extrusion plate, and the other end of the return spring is connected to the connecting plate.

[0008] Preferably, a plurality of limiting strips are evenly distributed on the outer side of the slide rod, and the limiting strips are slidably connected in the limiting grooves opened on the surface of the sleeve rod.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a mine skip hoist, including a base plate 1; A weighing and detection assembly 2 is installed on the surface of the base plate 1. The weighing and detection assembly 2 includes a hoist body 21 installed on the surface of the base plate 1, a skip body 22 set at the bottom of the base plate 1, a sleeve rod 23, a pressing plate 24, a connecting plate 25, a weight detection module 26, a hanging rope 27, a hook 28, a lifting steel rope 29, and a sliding rod 210. The lifting steel cable 29 is wound around the surface of the hoist body 21. Two sleeve rods 23 are symmetrically arranged above the skip body 22. The rope hanging component 27 is installed on the bottom surface of the sleeve rod 23, and the hook component 28 is installed on the upper surface of the skip body 22. The rope hanging component 27 and the hook component 28 are detachably connected. The slide rod 210 is slidably connected inside the sleeve rod 23. The extrusion plate 24 is installed at one end of the slide rod 210. The connecting plate 25 is installed inside the sleeve rod 23. The weight detection module 26 is installed on the side surface of the connecting plate 25 near the extrusion plate 24. Through the weighing and detection component 2 composed of the sleeve rod 23, the extrusion plate 24, and the weight detection module 26, the weight of the material in the skip body 22 can be detected in real time, replacing the traditional manual estimation or rough volume measurement method. It can accurately identify whether the material is overweight, avoid safety accidents such as wire rope breakage and brake failure caused by overweight, and significantly improve the operating safety of the hoist.

[0018] A return spring 211 is fitted on the surface of the slide bar 210. One end of the return spring 211 is connected to the extrusion plate 24, and the other end of the return spring 211 is connected to the connecting plate 25. When the skip unloads the material, the load disappears, and the return spring 211 automatically pulls the slide bar 210 to reset under the action of elastic restoring force, which drives the extrusion plate 24 to separate from the weight detection module 26, so that the weighing component quickly returns to the initial standby state.

[0019] Multiple limiting strips 212 are evenly distributed on the outer side of the slide rod 210. The limiting strips 212 are slidably connected in the limiting groove opened on the surface of the sleeve rod 23 to ensure that the slide rod 210 always moves vertically along the axis of the sleeve rod 23.

[0020] The limiting strips 212 are arranged in a circular array around the center point of the slide rod 210, so that the contact stress between the slide rod 210 and the sleeve rod 23 is evenly distributed on multiple limiting strips 212, avoiding wear or breakage caused by excessive force on a single limiting strip 212, and extending the service life of the slide rod 210 and the sleeve rod 23.

[0021] The weight detection module 26 is electrically connected to an external controller. The weight detection module 26 transmits the weight signal to the controller in real time, and the operator can remotely monitor the skip load through the controller. When the load exceeds the rated value, the controller can automatically issue an alarm signal, eliminating the need for manual real-time observation and improving monitoring efficiency.

[0022] The surface of the sleeve rod 23 is equipped with a disassembly and maintenance component 3, which includes a threaded rod 31 at the top of the sleeve rod 23 and a threaded sleeve 32 installed at one end of the lifting steel rope 29. The threaded rod 31 is installed at one end of the slide bar 210 through the sleeve rod 23. The threaded rod 31 is threaded inside the threaded sleeve 32. When it is necessary to replace the lifting steel rope 29 or repair the slide bar 210, the two can be separated simply by rotating the threaded sleeve 32. No special disassembly tools are required, which greatly simplifies the disassembly and assembly process and shortens the maintenance time.

[0023] Among them, the structure of the hoist body 21, the skip body 22, the weight detection module 26, the hoisting steel rope 29, etc. are existing technologies, and their working principle is a well-known technology. The appropriate model is selected according to the actual use.

[0024] Working principle and process: As the weight of the material inside the skip body 22 increases, the skip body 22 applies a downward pulling force to the hanging rope 27 through the hook 28. This pulling force is transmitted to the sleeve rod 23 in sequence. Since the slide rod 210 slides in the limiting groove of the sleeve rod 23 through the limiting strip 212 (the limiting strip 212 is distributed in a circumferential array to ensure that the slide rod 210 moves vertically without deviation), the sleeve rod 23 slides downward along the axis of the slide rod 210, driving the connecting plate 25 to move towards the extrusion plate 24. When the extrusion plate 24 contacts the weight detection module 26 on the surface of the connecting plate 25 and extrusion occurs, the weight detection module 26 converts the pressure signal into a weight electrical signal and transmits it to the external controller in real time. The controller analyzes the current weight signal based on the preset rated load threshold of the hoist. If the weight does not reach the rated load, loading can continue until it approaches the threshold. When the weight reaches the threshold, the controller issues a loading warning signal. If the weight exceeds the rated load, the controller immediately issues an overload alarm signal. During the loading process, when the slide bar 210 slides, it will compress the return spring 211 inside the sleeve bar 23. When the skip body 22 unloads the material, the load disappears. Under the action of the elastic restoring force, the return spring 211 drives the slide bar 210 to reset. The extrusion plate 24 separates from the weight detection module 26, and the equipment returns to the initial standby state. When the weight of the material reported by the weight detection module 26 is within the rated load range, the operator sends a start command to the hoist body 21 through the controller. The drive mechanism of the hoist body 21 operates, driving the hoisting steel rope 29 wound on the surface to wind up. The hoisting steel rope 29 is connected to the threaded rod 31 at the top of the slide rod 210 through the threaded sleeve 32 of the disassembly and maintenance component 3, transmitting the tension to the sleeve rod 23, and then driving the skip body 22 to rise vertically along the shaft through the rope hanging component 27 and the hook component 28. During the ascent, the weight detection module 26 continuously monitors the skip load. If a sudden load fluctuation occurs (such as material shift causing instantaneous overload), it can provide real-time feedback to the controller, which will adjust the hoisting speed or trigger protection as needed. When the skip body 22 rises to the ground unloading position, the hoist body 21 stops winding and controls the skip to unload. After unloading is completed, the hoist body 21 reverses its rotation, releases the hoisting steel rope 29, and the skip body 22 descends along the shaft to the underground loading position to enter the next transportation cycle. After the equipment stops running, rotate the threaded sleeve 32 at one end of the lifting steel rope 29 to disengage the threaded sleeve 32 from the threaded rod 31 at the top of the slide rod 210, thus separating the lifting steel rope 29 from the slide rod 210; at the same time, release the fastening of the rope hanging part 27 and the hook part 28 to separate the skip body 22 from the weighing and detection component 2, so as to facilitate the inspection and maintenance of each component separately.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
