Description

Technical Field

[0001] This utility model relates to the field of personnel transport devices in mine tunnels, specifically a personnel transport device for inclined shafts. Background Technology

[0002] As human society continues to develop, the total demand and variety of industrial raw materials and fossil energy raw materials are increasing, and as a result, more and more mines are being developed.

[0003] In mines, as the tunnels deepen and the mining point becomes increasingly distant from the mine entrance, minerals are transported via mine cars, while personnel are typically transported via winch-driven overhead cranes. A winch-driven overhead crane is a small, cable-operated passenger vehicle. This device is fixedly connected to the cable, and a drive unit moves the cable, thus moving the passenger vehicle. However, this type of device has a drawback: insufficient safety measures. If a person falls from the device, the operating winch-driven overhead crane may drag the passenger, causing secondary injury.

[0004] In view of this, in order to overcome the above-mentioned technical problems, this utility model designs an inclined shaft overhead passenger transport device, which solves the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides the following technical solution:

[0006] This utility model provides a passenger-carrying device for an inclined shaft, comprising: a main pole, a seat, a handle, a foot pedal, and a connecting rod.

[0007] The top of the main rod is fixedly connected to the connecting rod, the main rod and the connecting rod are perpendicular to each other, the steel cable passes through the connecting rod, the lower end of the main rod is fixedly connected to a seat and a footrest, the upper surface of the seat is horizontal, and the handle is slidably connected to the middle of the main rod.

[0008] The main rod is internally equipped with a telescopic locking mechanism, a lower sliding rod, an upper sliding rod, and a lower locking block; the telescopic locking mechanism includes a slide rail, a push rod, and a sliding pawl sleeve. The slide rail is located on the inner wall of the main rod, the push rod is slidably connected to the main rod, and the sliding pawl sleeve is rotatably slidably connected to the main rod.

[0009] A square through hole is provided in the middle of the main rod. The protruding part of the lower sliding rod passes through the square through hole and is fixedly connected to the handle. The lower sliding rod is fixedly connected to the push rod. The upper sliding rod is rotatably connected to the sliding pawl sleeve. The lower locking block is fixedly connected to the upper sliding rod. The upper locking block is fixedly connected inside the middle section of the connecting rod. The upper locking block and the lower locking block are used to fix and lock the steel cable. The telescopic locking mechanism is used to control the up and down movement of the lower locking block.

[0010] When using this device, the worker sits on the seat with their feet on the footrest and hands on the handle. The steel cable then drives the device's movement. When the worker lifts the handle, it moves the lower sliding rod and push rod upwards, triggering the telescopic locking mechanism. This mechanism is similar to the telescopic locking mechanism of a ballpoint pen; this is existing technology and will not be described in detail here. Triggering the telescopic locking mechanism causes the sliding pawl to move upwards and then rotate, finally moving downwards along the slide rail under gravity. This causes the upper sliding rod and lower locking block to move downwards, separating them, and the device is no longer fixed to the steel cable. To re-fix the device to the steel cable, simply lift the handle again.

[0011] Preferably, the upper sliding rod is connected to the telescopic locking mechanism via a compression spring, which provides pressure to the lower locking block. By providing continuous pressure to the lower locking block with the compression spring, the upper and lower locking blocks are made to grip the steel cable, while also providing space for the sliding pawl sleeve to move upward.

[0012] Preferably, a rebound spring is provided inside the lower section of the main rod, with one end of the rebound spring connected to the main rod and the other end connected to the lower sliding rod.

[0013] When a worker uses this device, if their hand is on the handle, the handle moves downwards from its initial position, compressing the return spring. If the worker slowly releases the handle, it will return to its initial position without triggering the telescopic locking mechanism. However, in the event of an emergency causing the worker to fall from the seat and suddenly release the handle, the return spring will quickly rebound, causing the lower sliding rod to move upwards beyond its initial position, triggering the telescopic locking mechanism. This will then cause the upper and lower locking blocks to separate from the steel cable. The advantage of this design is that it prevents the device from continuing to move with the steel cable after a worker falls from the seat in an emergency, thus avoiding secondary injury to the worker.

[0014] Preferably, both ends of the connecting rod are connected to buffer rods via buffer springs. When the upper locking block and the lower locking block separate, the device is no longer moved by the steel cable. At this time, the subsequent inclined shaft aerial personnel carrier will continue to move by the steel cable and will then collide with the stopped inclined shaft aerial personnel carrier in front. The buffer springs and buffer rods can reduce the impact force and prevent the inclined shaft aerial personnel carriers from colliding with each other, thus avoiding damage or injury to personnel.

[0015] Beneficial Effects: When using this device, the worker sits on the seat with their feet on the footrest and hands on the handle. As the handle moves downwards from its initial position, the return spring compresses. If the worker slowly releases the handle, it returns to its initial position without triggering the telescopic locking mechanism. However, in the event of a sudden incident causing the worker to fall from the seat and abruptly release the handle, the return spring will quickly rebound, causing the lower sliding rod to move upwards beyond its initial position, thus triggering the telescopic locking mechanism. This mechanism is based on the telescopic locking mechanism of a ballpoint pen, and is existing technology, so it will not be described in detail here. Triggering the telescopic locking mechanism causes the sliding pawl to move upwards and then rotate, finally moving downwards along the slide rail under gravity. This causes the upper sliding rod and lower locking block to move downwards, separating them, and the device is no longer fixed to the steel cable. This design prevents the device from being carried along by the steel cable and causing secondary injury to the worker in the event of a sudden fall. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will now be described in detail with reference to the accompanying drawings and embodiments. Regarding the safety of inclined shaft aerial passenger transport devices, the following solution is proposed:

[0027] like Figure 1-6 The aforementioned inclined shaft aerial passenger transport device includes a main pole 1, a seat 2, a handle 3, a foot pedal 4, and a connecting rod 5.

[0028] The top end of the main rod 1 is fixedly connected to the connecting rod 5. The main rod 1 and the connecting rod 5 are perpendicular to each other. A steel cable passes through the connecting rod 5. The lower end of the main rod 1 is fixedly connected to a seat 2 and a footrest 4. The upper surface of the seat 2 is horizontal. The handle 3 is slidably connected to the middle of the main rod 1.

[0029] The main rod 1 is internally slidably equipped with a telescopic locking mechanism 8, a lower sliding rod 31, an upper sliding rod 53, and a lower locking block 52; the telescopic locking mechanism 8 includes a slide rail, a push rod, and a sliding claw sleeve. The slide rail is set on the inner wall of the main rod 1, the push rod is slidably connected to the main rod 1, and the sliding claw sleeve is rotatably connected to the main rod 1.

[0030] The main rod 1 has a square through hole in the middle. The protruding part of the lower sliding rod 31 passes through the square through hole and is fixedly connected to the handle 3. The lower sliding rod 31 is fixedly connected to the push rod. The upper sliding rod 53 is rotatably connected to the sliding pawl sleeve. The lower locking block 52 is fixedly connected to the upper sliding rod 53. The upper locking block 51 is fixedly connected inside the middle section of the connecting rod 5. The upper locking block 51 and the lower locking block 52 are used to fix and lock the steel cable. The telescopic locking mechanism 8 is used to control the up and down movement of the lower locking block 52.

[0031] When using this device, the worker sits on seat 2, with feet on foot pedal 4 and hands on handle 3. The device then moves via a steel cable. When the worker lifts handle 3, it causes the lower sliding rod 31 and push rod to move upwards, triggering the telescopic locking mechanism 8. This telescopic locking mechanism 8 is based on the telescopic locking mechanism of a ballpoint pen; this structure is existing technology and will not be described in detail here. Triggering the telescopic locking mechanism 8 causes the sliding pawl sleeve to move upwards and then rotate, finally moving downwards along the slide rail under gravity. This causes the upper sliding rod 53 and lower locking block 52 to move downwards, separating the upper and lower locking blocks 51 and 52, thus freeing the device from being fixed to the steel cable. To re-fix the device to the steel cable, simply lift handle 3 again.

[0032] like Figure 1-6 The upper sliding rod 53 is connected to the telescopic locking mechanism 8 via a compression spring 54, which provides pressure to the lower locking block 52. By setting the compression spring 54 to provide continuous pressure to the lower locking block 52, the upper locking block 51 and the lower locking block 52 are made to grip the steel cable, while also providing space for the sliding pawl sleeve to move upward.

[0033] like Figure 1-6 The main rod 1 has a rebound spring 32 inside its lower section. One end of the rebound spring 32 is connected to the main rod 1, and the other end of the rebound spring 32 is connected to the lower sliding rod 31.

[0034] When a worker uses this device and holds onto handle 3, handle 3 moves downwards from its initial position, compressing the return spring 32. If the worker slowly releases handle 3, it will return to its initial position, and the telescopic locking mechanism 8 will not be triggered. However, if a sudden event occurs, causing the worker to fall from seat 2 and suddenly release handle 3, the return spring 32 will quickly rebound, causing the lower sliding rod 31 to move upwards beyond its initial position, triggering the telescopic locking mechanism 8. This will cause the upper locking block 51 and lower locking block 52 to separate from the steel cable. The advantage of this design is that it prevents the device from continuing to move with the steel cable after the worker falls from seat 2 in the event of a sudden incident, thus avoiding secondary injury to the worker.

[0035] like Figure 1-6The connecting rod 5 has buffer rods 7 connected to both ends by buffer springs 6. When the upper locking block 51 and the lower locking block 52 separate, the device is no longer moved by the steel cable. At this time, the subsequent inclined shaft aerial personnel carrier will continue to move by the steel cable and will then collide with the inclined shaft aerial personnel carrier that has stopped in front. The buffer springs 6 and buffer rods 7 can reduce the impact force and prevent the inclined shaft aerial personnel carriers from colliding with each other, which could lead to damage or injury to personnel.

[0036] Working principle: When using this device, the worker sits on seat 2, with feet on foot pedal 4 and hands on handle 3. Handle 3 moves downwards from its initial position, compressing the return spring 32. If handle 3 is slowly released, it will return to its initial position, and the telescopic locking mechanism 8 will not be triggered. However, if a sudden event occurs, causing the worker to fall from seat 2 and suddenly release handle 3, the return spring 32 will quickly rebound, causing the lower sliding rod 31 to move upwards beyond its initial position, thus triggering the telescopic locking mechanism 8. This telescopic locking mechanism 8 is based on the telescopic locking mechanism of a ballpoint pen; this structure is existing technology and will not be described in detail here. Triggering the telescopic locking mechanism 8 causes the sliding pawl sleeve to move upwards and then rotate, finally moving downwards along the slide rail under gravity. This causes the upper sliding rod 53 and the lower locking block 52 to move downwards, separating the upper and lower locking blocks 51 and 52, thus removing the device from its connection to the steel cable.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
