Description

Technical Field

[0001] This invention relates to the field of mine hoist car technology, and more particularly to a mine shaft hoist. Background Technology

[0002] In mining operations, transportation is carried out using mine hoist cars or cages. In large mines, main shafts and auxiliary shafts can be used for transporting goods and personnel respectively. However, in some small mines or in the early stages of shaft construction, only one hoist can be used for transportation. Due to regulations and safety concerns, mixed transport of people and goods is not allowed. Therefore, it is necessary to transport people or goods in different time periods. Generally, workers are transported underground first, and goods can be transported during most other time periods. In order to meet the needs of transporting people and goods at the same time, tracks need to be laid at the bottom of the car to facilitate the movement of mine cars into the car.

[0003] The separate transportation of people and goods at different times presents the following problems: When the mine car is inside the car, even with the wheels secured by wheel stops, the car still sways, and ore may spill from the top of the car and accumulate inside the car, affecting the safety of subsequent transportation operations. At the same time, when switching to personnel transportation, mixed loading of people and goods is not allowed, and timely cleanup is required to avoid safety accidents. When transporting goods, if the car door is open, workers may accidentally enter the car, and the mine car may then enter. Workers may remain inside the car due to a sense of impunity, and if supervision is not timely, it may lead to safety accidents.

[0004] The existing hoisting system has safety hazards that need to be addressed when separating personnel and goods transport. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a mine shaft hoist that addresses the above-mentioned technical deficiencies, thereby solving the safety hazards that exist in existing shaft hoists when transporting personnel and goods separately.

[0006] The technical solution adopted in this invention is: to provide a mine shaft hoist, including a headframe installed in the mine shaft, and a car that moves up and down within the headframe; the car loads workers or mine cars in different time periods, and further includes: The two tracks are spaced apart at the bottom of the car, and the mine car stops on the tracks when transporting goods. The support plate is located inside the car. One end is a hinged end that is hinged to the lower part of the car, and the other end is a movable end. The support plate includes several connecting plates that are hinged in sequence from the hinged end to the movable end. In the passenger transport state, the support plate rotates to a horizontal state and then overlaps the upper end of the track to support the workers. In the cargo transport state, the support plate partially covers the upper side of the mine car. A drive unit, disposed on the car, is used to drive the movable end to move around the hinged end.

[0007] To further optimize this technical solution, the driving unit includes: The flexible component is ring-shaped and rotatably mounted on the car. A connecting rope is fixedly connected at one end to the flexible component and at the other end to the movable end of the support plate. When the flexible component rotates, the connecting rope is used to move the movable end or tighten and fix the movable end.

[0008] To further optimize this technical solution, the car includes an outer body and an inner body, with an annular installation space between the outer body and the inner body. The flexible component is located within the installation space and sleeved around the inner body. The track is located at the bottom inside the inner body. Clearance spaces are provided on the vertical sidewalls and top sidewalls of the inner body, and the connecting rope passes through the clearance spaces.

[0009] To further optimize this technical solution, the support plate is provided in two parts, which are staggered front to back, and are respectively hinged to the left and right sides of the lower part of the inner compartment.

[0010] To further optimize this technical solution, the driving unit drives the two support plates to rotate respectively.

[0011] To further optimize this technical solution, the driving unit also includes: A drive motor is installed within the mounting space; The drive module drives the flexible component to rotate through the output of the drive motor.

[0012] Further optimization of this technical solution also includes: A support frame is provided, comprising several support frames, which are disposed at the bottom of the car interior, and the connecting plate is used to overlap the upper end of the support frame.

[0013] To further optimize this technical solution, the flexible component is a belt or chain.

[0014] To further optimize this technical solution, the wheels of the mine car can be fixed on the track using a car stopper.

[0015] The beneficial effects of this invention are as follows: 1. When switching between passenger and cargo transport modes, the support plate rotates accordingly, eliminating the need for a separate car. In passenger transport mode, the support plate rotates to a horizontal position and overlaps the track, forming a relatively flat support surface that can support workers. The track is not exposed, making it safer for personnel to stand.

[0016] 2. When in the cargo transport state, the support plate rotates to an inclined state, exposing the track and forming a physical barrier inside the car. When workers see this, it can effectively prevent them from accidentally entering the cargo transport car, reducing the occurrence of safety accidents.

[0017] 3. In the transport state, the support plate has a structure of several hinged connecting plates. The support plate can partially cover the upper side of the mine car, which can reduce the falling of ore inside the mine car, reduce subsequent cleaning work, reduce ore loss, improve safety during operation, and achieve safer loading and unloading.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0021] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figure 1-10 As shown, a mine shaft hoist includes a headframe 1 installed within the mine shaft, and a car 2 that moves up and down within the headframe 1; the car 2 carries workers or mine cars in different time periods, and further includes: Track 3, two tracks 3 are spaced apart at the bottom of the car 2, and the mine car stops on the track 3 when transporting goods; The support plate 4 is located inside the car 2. One end is a hinged end 401 that is hinged to the lower part of the car 2, and the other end is a movable end 403. The support plate 4 includes several connecting plates 402 that are hinged in sequence from the hinged end 401 to the movable end 403. In the passenger transport state, the support plate 4 rotates to a horizontal state and then overlaps the upper end of the track 3 to carry workers. In the cargo transport state, the support plate 4 partially covers the upper side of the mine car. A drive unit 5 is disposed on the car 2 and is used to drive the movable end 403 to move around the hinge end 401.

[0024] In use, the control system can switch between cargo transport and personnel transport modes. In personnel transport mode, the support plate 4 rotates to a horizontal position and overlaps the track 3, which provides support. At the same time, the drive unit 5 controls the movable end 403 of the support plate 4, so that the support plate 4 can stably maintain a horizontal position. The support plate 4 forms a relatively flat support surface, which can stably support the workers. After the workers are transported to or from the well, the system switches to cargo transport mode.

[0025] In the transport state, the support plate 4 rotates to an inclined state, moving away from the track 3 and exposing the track 3. The mine car can enter the car 2 from the outside using the rocking platform and the track 3, with the mine car positioned between a portion of the support plate 4 and the track 3. Subsequently, the movable end 403 of the support plate 4 descends, partially covering the mine car. Because the connecting plate 402 in the support plate 4 is in a movable hinged state, it can cover the mine car relatively closely with small gaps, effectively preventing ore from falling off the mine car and improving safety. At the same time, the support plate 4 provides downward pressure, reinforcing the positioning of the upper part of the mine car, reducing the overall swaying of the mine car, making transportation more stable, and reducing ore swaying and falling, as well as dust generation.

[0026] The tilting state of the support plate 4 can be divided into at least two stages. In the transport state, the support plate 4 initially tilts upwards at a small angle, such as a 30-degree angle with the bottom of the car 2. At this time, the support plate 4 occupies a large space inside the car 2, effectively preventing workers from accidentally entering even when the car 2 door is open and the platform is started. As the mine car approaches, the support plate 4 opens to a larger angle to facilitate its entry. A sloping structure can also be installed at the front of the mine car to gradually expand the support plate 4. After the mine car enters, the movable end 403 of the support plate 4 rotates and descends to cover the mine car. During unloading, the support plate 4 opens again. The opening angle and coverage area of ​​the support plate 4 can be adapted to the size of the mine car, which is a small and low-profile loading device.

[0027] The front end of the car 2 is open, and a door for the car 2 can be set as needed, such as a lifting door curtain, which is a conventional setting and is not shown in this invention.

[0028] Drive unit 5 can remain locked.

[0029] Furthermore, the driving unit 5 includes: The flexible component 501 is annular and rotatably mounted on the car 2; The connecting rope 502 is fixedly connected at one end to the flexible member 501 and at the other end to the movable end 403 of the support plate 4. When the flexible member 501 rotates, the connecting rope 502 is used to drive the movable end 403 to move or tighten and fix the movable end 403.

[0030] Furthermore, the flexible component 501 is a belt or chain.

[0031] In use, the flexible component 501 is rotatably mounted, and the connecting rope 502 provides tension to the movable end 403 of the support plate 4. When the flexible component 501 rotates counterclockwise, the connecting rope 502 pulls the movable end 403 of the support plate 4 upward, causing the support plate 4 to tilt. When the mine car moves onto the track 3, the flexible component 501 rotates clockwise, providing downward tension through the connecting rope 502, so that the support plate 4 partially covers the mine car and can stably cover and press down the ore inside the mine car. In the passenger transport mode, the flexible component 501 rotates clockwise, pulling down the support plate 4 so that the support plate 4 abuts against the track 3, maintaining a horizontal state for passenger transport.

[0032] The support plate 4 rotates around the hinge end 401, which is located in the lower part of the car 2. The connecting rope 502 is relatively long, sufficient to meet the length requirements when pulling upwards. During the rotation of the support plate 4, the connecting rope 502 naturally straightens. The support plate 4 may not remain perfectly straight, but this does not affect the final result. Figure 8 As shown, when the connecting rope 502 needs to tighten the support plate 4, for example when the support plate 4 is in a horizontal state and carrying people, the flexible part 501 rotates clockwise, and the connection between the connecting rope 502 and the flexible part 501 passes the movable end 403 of the support plate 4 and continues to move clockwise. Finally, the connecting rope 502 is tightened and the support plate 4 remains horizontal.

[0033] Furthermore, the car 2 includes an outer body 201 and an inner body 202, with an annular installation space between the outer body 201 and the inner body 202. The flexible component 501 is located within the installation space and sleeved around the inner body 202. The track 3 is located at the bottom inside the inner body 202. Clearance spaces 2021 are provided on the vertical sidewalls and top sidewalls of the inner body 202, and the connecting rope 502 passes through the clearance spaces 2021.

[0034] In use, the car 2 is divided into inner and outer layers, with a ring-shaped installation space in the middle, providing space for the flexible component 501 and the drive unit 5, while also making its own structure safer. The inner car body 202 is fixed inside the outer car body, and the fixed connection structure avoids the flexible component 501, etc.

[0035] The clearance space 2021 on the inner side wall of the compartment is the free movement space of the connecting rope 502 when the flexible component 501 rotates in a ring. The cross-section of the clearance space 2021 is an inverted "L" shape. At the end of the clearance space 2021, the flexible component 501 continues to rotate and pull the connecting rope 502. Then the end of the clearance space 2021 forms a fulcrum for the connecting rope 502, which can make the connecting rope 502 taut and straighten the support plate 4.

[0036] At the right angle where the vertical side wall and the top side wall of the inner compartment connect, the hinge end 401 of the support plate 4 is diagonally opposite. At this point, the required length of the connecting rope 502 is at its minimum requirement. Otherwise, the connecting rope 502 cannot pull the movable end 403 of the support plate 4. That is, at this diagonal position, the connecting rope 502 can straighten the support plate 4, so that the support plate 4 is at an open angle. Then the flexible part 501 continues to rotate counterclockwise, and the connecting rope 502 moves to the left. Using the end of the clearance space 2021 as the fulcrum, the support plate 4 can be straightened again, and the support plate 4 is at a larger open angle.

[0037] The connecting rope 502 can be a steel wire rope, etc., capable of stably bearing tensile force. The flexible component 501 can be a timing belt, making controlled drive easier. The drive position can be monitored by setting a corresponding detection device.

[0038] Furthermore, there are two support plates 4, which are staggered front to back, and are respectively hinged to the left and right sides of the lower part of the inner compartment 202.

[0039] In use, two support plates 4 are respectively set on the left and right sides of the inner compartment. The two support plates 4 can be staggered by being set front and back to avoid interference. The two support plates 4 distributed on the left and right can occupy the internal space of the inner compartment more comprehensively, reducing the possibility of workers accidentally entering, and the blocking effect is better. At the same time, they can cover the mine car more stably. The more symmetrical force and coverage on the left and right sides are more effective in preventing ore from falling.

[0040] Two support plates 4 can be located on the front and rear sides respectively, each occupying half of the space. The middle part of the support plate 4 can be composed of connecting plates 402 that are hinged from left to right to form a flexible plate assembly. Multiple flexible plate assemblies are distributed at intervals along the front-to-back direction. The flexible plate assemblies of the two support plates 4 are arranged alternately and can be spliced ​​to form a complete support surface. The end of each flexible plate assembly is independently connected to the flexible component 501 through a connecting rope 502, so the two connecting plates 402 do not interfere with each other.

[0041] Furthermore, the driving unit 5 drives the two support plates 4 to rotate respectively.

[0042] In use, when an additional support plate 4 is added, the drive unit 5 simply adapts accordingly. The flexible component 501 consists of at least two lines with opposite directions but the same driving principle. Multiple flexible components 501 can be set as needed, divided into two groups, to drive and control the two support plates 4 respectively.

[0043] Furthermore, the driving unit 5 also includes: The drive motor 503 is disposed within the mounting space; The drive module 504 drives the flexible component 501 to rotate through the output end of the drive motor 503.

[0044] In use, the drive unit 5 drives the flexible component 501 through the drive module 504. For example, when the flexible component 501 uses a chain, a sprocket is used; when the flexible component 501 uses a timing belt, a pulley is used; and for a regular belt, a more stable driving force needs to be provided to the clamping roller, and a brake structure is needed to lock the belt to provide more stable positioning and locking capabilities. The drive module 504 is a conventional adapter and will not be described in detail in this application.

[0045] Furthermore, it also includes: The support frame 6 is provided in several parts. The support frame 6 is located at the bottom of the car 2. The connecting plate 402 is used to attach to the upper end of the support frame 6.

[0046] In use, the support frame 6 is arranged front and back and spaced along the left and right sides to support the multiple connecting plates 402 of the support plate 4. More connecting plates 402 can be set and hinged in sequence, which can cover the shape adaptability. The layout of the support plate 4 is adapted to it and provides stable bottom support.

[0047] Furthermore, the wheels of the mining car can be secured on the track 3 using a wheel catcher.

[0048] In use, although the support plate 4 can provide positioning for the mine car, in order to ensure safety, reduce damage to the support plate 4, and extend its service life, a wheel stop can be used to fix and limit the wheels of the mine car in a conventional manner, and the support frame 6 can be arranged to avoid it. This application does not show the wheel stop.

Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
