Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise specified, use of directional words such as "upper" and "lower" generally means that the terms are defined with reference to the drawing plane of the corresponding drawing, and "inner" and "outer" mean that the corresponding part is contoured both inwardly and outwardly. The use of the terms first and second do not denote any order or importance, but rather the terms first and second are used to distinguish one element from another. In addition, when the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements, unless otherwise indicated.

The transport of people and materials in the mine shaft is usually effected by means of a cage 6. In order to facilitate the ascending and descending of the cage 6, a cage guide 5 extending in the up-down direction is arranged on the inner side of the shaft wall 7 of the shaft well, and the cage guide 5 can be reinforced and fixed through a steel frame structure 8 built by I-beams for example. The cage 6 is provided with a rail on which the cage 5 slides, so that the cage 6 can slide up and down in the cage 5 along the rail.

To avoid casualties caused by the large impact force generated by accidental falling of the cage 6, the present disclosure provides a parking device for the cage, as shown in fig. 1 and 2. The parking device is arranged on the inner wall of a cage guide 5 and comprises a stop block 1 and a buffer mechanism 2. The upper end of the stop block 1 may be mounted on the inner wall of the tank guide 5 by, for example, a hinge bracket 4, and the hinge bracket 4 has one end mounted on the inner wall of the tank guide 5 and the other end hinged to the stop block 1 by a rotating shaft so that the stop block 1 can rotate around the rotating shaft. The lower end of the stop block 1 is connected with the buffer mechanism 2, and the opening of the cage guide 5 is gradually narrowed from top to bottom under the support of the buffer mechanism 2. The cage guide 5 with the opening gradually narrowed from top to bottom can provide extrusion force towards the interior of the cage guide 5, so that the resistance of the cage 6 in the falling process is increased, and the falling speed and the falling impact force of the cage 6 are reduced as much as possible.

As shown in fig. 2 and fig. 3, the buffer mechanism 2 may have a slide rail 21 and a slide rod 22 slidably engaged with the slide rail 21 in a transverse direction, and one end of the slide rod 22 extending out of the slide rail 21 is connected to the stopper 1, so that the slide rod 22 can extend and retract along the slide rail 21 along with the swing of the stopper 1. Further, an elastic member 23 capable of being pushed by the slide rod 22 to deform is disposed inside the slide rail 21. The cage 6, during the fall, presses the stop block 1, the stop block 1 pushing against the slide 22 to gradually compress the elastic element 23. Since the compression deformation of the elastic member 23 is a gradual process, the buffer mechanism 2 can avoid the hard collision of the stop block 1 with the falling cage 6, so as to gradually reduce the impact force when the cage 6 falls until the cage 6 stops falling.

According to an embodiment of the present disclosure, as shown in fig. 3, the elastic member 23 may be a plurality of return springs with different lengths, and the deformation direction of the plurality of return springs is the same as the sliding direction of the sliding rod 22, so that the return springs can form a step-by-step buffer according to the magnitude of the impact force generated when the cage 6 falls down. Of course, the elastic member 23 may be made of elastic rubber. According to the difference of impact force generated when the cage 6 falls down, the stop block 1 pushes the sliding rod 22 with different force, and the sliding rod 22 firstly contacts with and compresses the return spring with the longest length to form the first-stage buffering. If the impact force of the falling cage 6 is too large, the sliding rod 22 will start to compress the return spring with a shorter length, which together with the elastic restoring force of the return spring with the longest length provides a counter-supporting force to the sliding rod 22 to form a second level of cushioning. The number of the return springs can be set according to the weight of the cage 6, the height of the parking device from the bottom of the well and other factors, so that the gradual buffering is realized.

In the present disclosure, as shown in fig. 3, the slide rail 21 may be configured as a closed housing, and the cross-sectional shape of the housing may be set to be square, circular, or any other suitable shape. A partition plate 24 is arranged in the shell, and the partition plate 24 can be pushed by the sliding rod 22 to slide in the shell along the same direction as the sliding of the sliding rod 22. The partition 24 divides the housing into a first chamber 211 and a second chamber 212, and the elastic member 23 is disposed between the partition 24 and the bottom of the housing, so that pushing the partition 24 can compress the elastic member 23. The housing is further filled with hydraulic oil, and the partition plate 24 is provided with a first through hole 241 for allowing the hydraulic oil to flow between the first chamber 211 and the second chamber 212. When the stop block 1 is not pressed by the cage 6, the elastic member 23 in the buffer mechanism 2 pushes the slide rod 22 to the outermost side under the elastic restoring force. When the cage 6 falls down, the stop block 1 pushes the slide rod 22, the slide rod 22 drives the partition plate 24 to move towards the bottom direction of the shell, the elastic element 23 is compressed, and hydraulic oil slowly flows from the first chamber 211 to the second chamber 212 through the first through hole 241 on the partition plate 24 in the compression process. Since the hydraulic oil can slowly flow in the first chamber 211 and the second chamber 212, the pushing force of the stopper 1 against the slide rod 22 is approximately constant, and the stability of the operation of the buffer mechanism 2 can be improved.

In the present disclosure, as shown in fig. 3, the slide bar 22 may be configured in a T-shape, including a bar portion 221 and a slide portion 222, the shape of the slide portion 222 matching the shape of the inner wall of the housing, and a friction surface formed between the outer circumferential surface of the slide portion 222 and the inner wall of the housing. When the sliding rod 22 is pushed by the stop block 1 to move toward the partition plate 24, a friction surface formed between the outer peripheral surface of the sliding portion 222 and the inner wall of the housing can increase the resistance of the sliding portion 222 to the movement of the partition plate 24, and the reaction force of the friction force between the two can play a role of reversely supporting the stop block 1. The friction surface formed between the outer peripheral surface of the sliding portion 222 and the inner wall of the housing may be a rough surface formed between the outer peripheral surface of the sliding portion 222 and the inner wall of the housing, or an object having a large friction force, such as a rubber pad, may be provided on each of the outer peripheral surface of the sliding portion 222 and the inner wall of the housing.

The slide rod 22 having the T-shaped structure of the present disclosure and the design in which the friction surface is formed between the outer peripheral surface of the slide portion 222 and the inner wall of the housing may be applied to the above-described damper mechanism having the hydraulic damping function. The sliding portion 222 is provided with a second through hole 223, and the position of the second through hole 223 corresponds to the position of the first through hole 241. When the sliding rod 22 is pushed by the stopper 1 to move toward the partition 24, a friction surface formed between the outer peripheral surface of the sliding portion 222 and the inner wall of the housing is a first-stage buffer, the sliding rod 22 continues to move toward the partition 24 until contacting the partition 24 and drives the partition 24 to move together toward the bottom of the housing to compress the elastic member 23 and hydraulic oil, and the hydraulic oil can flow from the first chamber 211 to the second chamber 212 through the first through hole 241 and the second through hole 223 on the sliding portion 222, which is a second-stage buffer.

According to another embodiment of the present disclosure, the slide rod 22 having the T-shaped structure and the design in which the friction surface is formed between the outer circumferential surface of the slide portion 222 and the inner wall of the housing may not be applied to the damper mechanism having the hydraulic damping function, that is, the damper mechanism 2 includes the friction damping and the elastic damping. The slide rail 21 is a sealed housing, and the elastic member 23 is disposed between the sliding portion 222 and the bottom of the housing. When the sliding rod 22 is pushed by the stopper 1 to move toward the partition 24, a friction surface formed between the outer peripheral surface of the sliding portion 222 and the inner wall of the housing is a first-stage buffer, and the sliding rod 22 continues to move toward the partition 24 until contacting the partition 24 and driving the partition 24 to move together toward the bottom of the housing to compress the elastic member 23, which is a second-stage buffer.

In the present disclosure, as shown in fig. 3, the sliding rod 22 may be fixedly connected to the sliding rail 21 by a first threaded member 25, and when the cage 6 drops and pushes the sliding rod 22, the first threaded member 25 is broken and the sliding rod 22 starts to slide in the sliding rail 21. Since the slide bar 22 can be fixedly connected to the slide rail 21 by the first screw 25, that is, the first screw 25 fixes the position of the slide bar 22, the support effect on the stop block 1 is maintained. When the stop block 1 is pushed by the cage 6, if the impact force of the falling is not large, namely the impact force is not enough to break the first threaded member 25, the cage 6 is clamped at the parking device; when the impact force of the falling is large, the first threaded part 25 is broken by the jacking force of the cage 6 on the stop block 1, and after the first threaded part 25 is broken, the sliding rod 22 starts to slide in the sliding rail 21 to realize the friction buffering, the elastic buffering and the hydraulic buffering, namely the first threaded part 25 is formed into the first-stage buffering.

Further, as shown in fig. 2, the sliding rod 22 may be fixedly connected to the lower end of the stopper 1 by the second screw 3, and the connection strength between the sliding rod 22 and the stopper 1 is greater than the connection strength between the sliding rod 22 and the sliding rail 21. This ensures that the second threaded element 3 between the slide rod 22 and the stop block 1 does not break first before the first threaded element 25 breaks due to the impact force of the cage 6, which would affect the damping mechanism 2 to exert its damping effect.

According to an embodiment of the present disclosure, as shown in fig. 2, the stopper block 1 may be configured as a wedge-shaped block gradually widening from an upper end to a lower end. The wedge-shaped block has a shape gradually widening from the upper end to the lower end, so that the opening of the cage guide 5 is gradually narrowed, inward extrusion force can be formed on the falling cage 6, and resistance when the cage 6 falls is increased by using the shape of the stop block 1. Referring to fig. 1 as well, the stopper block 1 may be provided in plurality in the up-down direction. The number of stop blocks 1 can be set according to the actual requirements, such as the weight of the cage 6 and the height from the bottom of the well.

The stopper blocks 1 may be symmetrically disposed at both sides of the inner wall of the cage guide 5 so that the cage guide 5 is formed as an inverted trapezoidal opening which is gradually narrowed from the top to the bottom. Compare in only setting up backstop 1 on one side inner wall of cage guide 5, all be provided with backstop 1 on the both sides inner wall of cage guide 5, can form inward extrusion force from cage 6's both sides, improve the effect of buffering.

Under normal conditions, the cage 6 comprises a main cage and an auxiliary cage which are connected together, a cage guide for lifting the main cage and a cage guide for lifting the auxiliary cage are respectively arranged in the well, the auxiliary cage is driven by the main cage to lift up and down in the cage guide 5, therefore, as shown in fig. 1, the parking device can be arranged on the inner wall of the cage guide 5 on one side of the main cage, and when the main cage stops falling, the auxiliary cage also stops falling.

A parking device for a cage guide, which can be fully implemented according to the present disclosure, is described below by way of example. As shown in fig. 1 to 3, when the cage 6 accidentally drops, the body of the cage 6 presses the wedge-shaped stopper 1 disposed on the inner wall of the cage guide 5, and the wedge-shaped stopper 1 forms inward pressing force on the cage 6. The cage 6 continues to drop and pushes the stopper plate 1 to swing outward. Due to the high impact force when the cage 6 is dropped, the first screw 25 connected between the slide rail 21 and the T-shaped slide bar 22 is destructively broken and the slide bar 22 starts to slide within the slide rail 21. In the process that the sliding rod 22 moves towards the bottom of the closed sliding rail 21, the friction surface formed between the sliding part 222 of the T-shaped sliding rod 22 and the inner wall of the sliding rail 21 can slow down the speed of the sliding rod 22 moving towards the bottom of the sliding rail 21. The slide rod 22 continues to move towards the bottom of the slide rail 21 until it contacts the partition 24 and brings the partition 24 together towards the bottom of the slide rail 21 to compress the elastic member 23 and the hydraulic oil, which flows from the first chamber 211 to the second chamber 212, and the slide rod 22 continues to move until the elastic member 23 is completely compressed.

According to a second object of the present disclosure, there is provided a cage guide, as shown in fig. 1, the cage guide 5 including the parking device described above, the parking device being provided on an inner wall of the cage guide 5. The lower end of the inner wall of the cage guide 5 is provided with a reinforcing block 9 for reinforcing the cage guide 5. The reinforcing block 9 can be fixed to the inner wall of the guide 5 by means of i-beams, and the strength of the connection between the reinforcing block 9 and the guide 5 can be varied by adjusting the density of the i-beams. When the cage 6 falls down, the stop blocks 1 on the two sides of the inner wall of the cage 5 generate outward pushing force, so that the cage 5 bears outward pushing force. The reinforcing block 9 at the bottom of the cage guide 6 can prevent the whole framework of the cage guide 5 from deforming or loosening, and maintain the safe operation of the cage 6 on the cage guide 5. Likewise, the reinforcing blocks 9 may also be configured as wedge-shaped blocks that widen gradually from the upper end to the lower end to further ensure a smooth landing of the dropped cage 6.
