Description

Technical Field

[0001] The present invention relates to a tank stabilizing compensating receiving and cradle commonly used in the shaft opening, shaft bottom and intermediate level of a mine shaft, and in particular to a tank stabilizing compensating receiving and cradle suitable for a wire rope tankway and used for absorbing the changing load of a tank cage and compensating for the elongation of a lifting wire rope, and belongs to the technical field of mining machinery and equipment. Background Art

[0002] Mine shaft hoisting is the main mode of mine transportation. With the development of my country's coal industry, mine auxiliary shaft hoisting has gradually developed in the direction of depth and weight, that is, the hoisting depth exceeds 800 meters and the total hoisting weight exceeds 80 tons. The cage is an essential equipment for the upper and lower personnel and materials in the mine shaft hoisting. The tankway is the guide device of the cage, which can usually be divided into two types: rigid tankway and flexible tankway. The rigid tankway usually fixes the rails on various metal steel sections or special reinforced concrete tankway beams in the shaft; while the flexible tankway uses various forms of wire ropes and is installed by fixing the two ends of the wire rope. The wire rope tankway is currently the only flexible tankway. Compared with the rigid tankway, the wire rope tankway does not require the installation of a tankway beam. It has the advantages of small installation workload, short construction time, simple maintenance, high-speed operation, stable and reliable, and low ventilation resistance. It is widely used in medium and deep mines.

[0003] However, the rigidity of the wire rope tankway is much lower than that of the steel tankway, and the movable amount of the cage of the wire rope tankway is much greater than that of the rigid tankway. The "Coal Mine Mining Design Manual" stipulates that when using a wire rope tankway, the minimum gap between the most protruding part of the cage and the shaft wall and shaft beam is 350mm, the minimum gap between the cages is 450mm, and when an anti-collision rope is installed, the minimum gap between the cages is 200mm. This makes it a major problem to overlap and position the cage of the vertical shaft hoisting system using a wire rope tankway with the external fixed track. Usually, a rigid tankway is required to stabilize the tank. For deep mines, the cage is often affected by the greater elasticity of the lifting wire rope and has a greater up and down movement problem, which leads to the cage often having 6 degrees of freedom when performing a tank stop operation at the middle horizontal stop position: up, down, left, right, front, and back. The existing intermediate-level tank stabilizing and shaking platform device can achieve a good tank supporting and stabilizing effect for rigid tankways, but for wire rope tankways, on the one hand, in order to meet the requirement of a minimum clearance of 350mm, a larger flip tank supporting claw is usually provided so that the flip tank supporting claw can be supported on the bottom of the cage after being flipped out, which not only invisibly increases the size of the equipment and the power consumption of the equipment, but also is inconvenient for underground installation; on the other hand, the existing tank stabilizing and shaking platform device often has a better limiting effect on the up and down degrees of freedom, but the limiting effect on other directions of freedom is not ideal, which not only affects production efficiency but also poses a great safety hazard. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a tank stabilizing and compensating rocking platform for a wire rope tankway for vertical shaft hoisting, which can achieve stable and reliable overlap between the inner track of the tank cage and the external fixed track under the premise of firmly supporting and stabilizing the tank, thereby realizing safe and smooth entry and exit of mine cars, and is particularly suitable for wire rope tankways in medium and deep mines.

[0008] The cradle part is arranged at the front of the top of the fixed frame, including the cradle and the linkage mechanism; the rear end bottom of the cradle is hingedly installed on the fixed frame, and the cradle is fixedly provided with a track II arranged along the front-back direction, and the track II is docked with the track I; the linkage mechanism is positioned at the top of the mobile frame corresponding to the hinge position of the cradle, and the linkage mechanism is a structure that converts the linear motion of the mobile frame along the front-back direction into a circular motion of the cradle rotating around its hinge axis. When the mobile frame slides forward and extends out, the linkage mechanism controls the cradle to flip forward along the hinge center of the cradle, and when the mobile frame slides backward and retracts, the linkage mechanism controls the cradle to flip backward along the hinge center of the cradle;

[0009] The centralized electric control part includes a controller, a movable frame sliding control circuit and a tank holding claw flipping control circuit. The controller is electrically connected to the sliding guide driving component and the rotating arm rotation driving component respectively.

Therefore, the movable frame can be controlled to move a large amount of the movable frame closer to or away from the tank cage by controlling the sliding guide driving component. Therefore, the structural dimensions of the flipping tank supporting claw can be greatly reduced on the premise of meeting the requirement of a minimum gap of 350mm between the most protruding part of the tank cage and the shaft wall and the shaft beam, so that the overall structure of the tank stabilizing and compensating cradle is flattened and easy to install. Since the movable frame is provided with a tank cage top clamping and positioning arm which is symmetrically arranged on the left and right, and the front end of the tank cage top clamping and positioning arm is a positioning inclined surface structure which matches the chamfered vertical surface angle of the tank cage, when the movable frame slides forward and extends close to the tank cage, the positioning inclined surface structure of the tank cage top clamping and positioning arm which is symmetrical on the left and right can be clamped against the chamfered vertical surface of the tank cage, so that the movable frame can slide forward and extend out to approach the tank cage. That is, the tank stabilizing operation is performed with limited freedom in the four directions of left, right, front and rear of the tank cage, and the tank stabilizing operation with limited freedom in the lower direction of the tank cage can be achieved after the tank holding claw is flipped out and supported at the bottom of the tank cage, thereby achieving the tank stabilizing operation with limited freedom in the five directions of the tank cage and ensuring the stability of the tank cage entering and exiting the mine car; since a force limit compensation mechanism and a limit block are provided, and the axis of the articulated axis I passes the articulation dead point position of the force limit compensation mechanism and the swivel arm when the swivel arm limit top is against the limit block, during normal tank holding operation, under the rigid support of the swivel arm, the support seat and the frame, the variable load transmitted by the tank cage acts on the mobile frame, and the kinetic energy of the variable load transmitted by the tank cage can be absorbed by the force limit compensation mechanism on the one hand, and by the sliding guide drive component on the other hand, thereby not only a larger buffer stroke can be obtained, but also multi-level buffering can be achieved, thereby achieving a better tank stabilizing effect, which is particularly suitable for wire rope tankways in medium and deep mines.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings (hereinafter referred to as Figure 2 The left side direction is described as the front).

[0026] like Figure 2 As shown, the tank stabilizing and compensating cradle for the vertical shaft hoisting wire rope tankway comprises a frame part 1, a tank supporting part 2, a cradle part 3 and a centralized electric control part.

[0027] The frame part 1 is a frame structure, including a fixed frame 11 and a movable frame 12; the top rear part of the fixed frame 11 is provided with a track I fixedly arranged in the horizontal front-to-back direction; the movable frame 12 is installed inside the fixed frame 11 through a sliding guide mechanism arranged along the front-to-back direction, and the sliding guide mechanism can be a guide wheel and track structure arranged in cooperation, or can be other sliding guide structures such as a guide protrusion and guide groove structure arranged in cooperation, and a sliding guide driving component 13 is also arranged between the movable frame 12 and the fixed frame 11, and the sliding guide driving component 13 can be as follows Figure 2 The telescopic hydraulic cylinder structure shown in the figure may also be a gear rack structure driven by an electric motor or a hydraulic motor, or other linear reciprocating motion driving structure. By controlling the action of the sliding guide driving component 13, the movable frame 12 can be moved forward and backward inside the fixed frame 11 through the sliding guide mechanism; Figure 3 As shown, the top of the movable frame 12 is provided with a cage top-supporting clamping positioning arm 14 extending forward and symmetrically arranged on the left and right. Since the tankway shaft is usually a structure with a circular cross-section, and the tank cage 4 with a cubic structure is usually provided with chamfered facades at four corners in the vertical direction to adapt to the circular tankway shaft and minimize the damage to the inner wall of the tankway shaft caused by the swing of the tank cage 4, the front end of the cage top-supporting clamping positioning arm 14 is a positioning inclined surface structure that matches the angle of the chamfered facade of the tank cage 4. When the movable frame 12 slides and extends forward, the positioning inclined surface structure of the cage top-supporting clamping positioning arm 14, which is symmetrical on the left and right, can be clamped against the chamfered facade of the tank cage 4.

[0028] The tank support part 2 is installed inside the mobile frame 12. Figure 4 , Figure 6 As shown, it includes a support seat 21, a rotating arm 22, a force limiting compensation mechanism 23, a can-turning claw 24 and a limit block 26; the support seat 21 is fixedly mounted on the rear part of the mobile frame 12; the rear end of the rotating arm 22 is rotatably mounted on the support seat 21 through a support bearing arranged in the left and right directions in the axial direction, and the rotating arm 22 is provided with a rotating arm rotating driving component 25 that can drive the rotating arm 22 to rotate. The rotating arm rotating driving component 25 can be a rotating driving structure that controls the rotation of a rotating spindle located at the rear end of the rotating arm 22 by an electric motor, or a rotating driving structure that controls the rotation of a rotating spindle located at the rear end of the rotating arm 22 by a hydraulic motor, or a telescopic driving structure that controls the rotation of the rotating arm 22 by connecting a rotating arm driving hydraulic cylinder to a rocker rod fixedly arranged at the rear end of the rotating arm 22, or other driving structures; as Figure 5 As shown, the force limiting compensation mechanism 23 is a telescopic cylinder structure, including a cylinder body, a compression spring plate 231 and a compression spring 232. The compression spring plate 231 is slidably matched and arranged inside the cylinder body part. The compression spring 232 is arranged inside the cylinder body and is arranged between the compression spring plate 231 and the cylinder bottom of the cylinder body. A buffer rod 233 coaxially arranged therewith is installed on the compression spring plate 231, and the buffer rod 233 is extended to the outside of the cylinder body. The rear end of the cylinder body of the force limiting compensation mechanism 23 is connected to the front end of the rotating arm 22 through a connecting rod 234 coaxially fixedly connected thereto through an articulated shaft I 22 arranged in the left and right directions in the axial direction. 1 is hingedly installed; one corner of the flip can holding claw 24 with a triangular structure as a whole is a claw structure protruding forward, the bottom corner of the flip can holding claw 24 located below the claw structure is hingedly installed with the front end of the buffer rod 233 through a hinge shaft II 241 arranged in the axial direction along the left and right directions, and the other corner of the flip can holding claw 24 located behind the claw structure is hingedly installed at the front end of the mobile frame 12 through a hinge shaft III 242 arranged in the axial direction along the left and right directions; the limit block 26 is fixedly arranged on the mobile frame 12 at the position corresponding to the rotating arm 22. In the normal can holding state, such as Figure 4 As shown, when the rotating arm rotation driving component 25 drives the rotating arm 22 to rotate so that the axis of the hinge shaft I 221 passes through the hinge dead point position between the force limiting compensation mechanism 23 and the rotating arm 22, the rotating arm 22 can be limited to abut against the limit block 26.

[0029] The cradle part 3 is arranged at the top front part of the fixed frame 11, including a cradle 31 and a linkage mechanism 32; the rear end bottom of the cradle 31 is hingedly installed on the fixed frame 11, and a track II arranged along the front-to-back direction is fixedly provided on the cradle 31, and the track II is docked with the track I; the linkage mechanism 32 is positioned at the top of the mobile frame 12 corresponding to the hinge position of the cradle 31, and the linkage mechanism 32 is a structure that converts the linear motion of the mobile frame 12 along the front-to-back direction into a circular motion of the cradle 31 rotating around its hinge axis, and the linkage mechanism 32 can be a gear installed at the hinge position of the cradle 31 and a matching gear. The rack structure installed on the mobile frame 12 can also be a cam structure installed at the hinge position of the cradle 31 and the mobile frame 12, or a torsion spring installed at the hinge position of the cradle 31 and a wedge structure installed at the hinge position of the cradle 31 and other transmission structures such as the mobile frame 12. When the mobile frame 12 slides forward and extends out, the linkage mechanism 32 controls the cradle 31 to flip forward along the hinge center of the cradle 31 and gradually become a horizontal overlapping state. When the mobile frame 12 slides backward and retracts, the linkage mechanism 32 controls the cradle 31 to flip backward along the hinge center of the cradle 31 and gradually become a tilted and yielding state.

[0030] The centralized electric control part includes a controller, a movable frame sliding control circuit and a tank holding claw flipping control circuit. The controller is electrically connected to the sliding guide driving component 13 and the rotating arm rotation driving component 25 respectively.

[0031] When the tank stabilizing compensation support cradle of the vertical shaft hoisting wire rope tankway is installed in the middle horizontal tank cage parking position in the wire rope tankway, Figure 1 As shown, the tank stabilizing compensation receiving cradle of the present vertical shaft hoisting wire rope tankway needs to be set as two sets symmetrically with respect to the tank cage 4; in the initial state, the movable frame 12 is in a state of being completely retracted inside the fixed frame 11, the flip tank claw 24 is in a state of being flipped into the movable frame 12, and the cradle 31 is in a state of yielding with the front end tilted up. At this time, there is no obstacle on the inner wall of the tankway shaft, and the tank cage 4 can move up and down smoothly in the tankway shaft;

[0032] After the cage 4 stops at the cage parking position and is in place, the controller first starts the sliding control circuit of the mobile frame, and the controller controls the sliding guide driving component 13 to make the mobile frame 12 slide forward and extend. During the process of the mobile frame 12 moving forward to approach the cage 4, the linkage mechanism 32 drives the rocking table 31 to flip forward along the hinge center of the rocking table 31. After the mobile frame 12 moves forward to the set position, as shown in FIG. Figure 3As shown in the figure, the positioning inclined surface structure of the cage top clamping positioning arm 14 is pressed against the chamfered vertical surface of the cage 4 in a clamping state, and at the same time, the cradle 31 is horizontally overlapped on the receiving platform of the cage 4 to complete the cradle overlap action. At this time, the four chamfered vertical surfaces of the cage 4 in the vertical direction are respectively clamped by the positioning inclined surface structures of the four cage top clamping positioning arms 14, thereby realizing the stabilizing operation of the cage 4 with limited freedom in the four directions of left, right, front and back. Then the controller starts the tank holding claw flipping control circuit, as shown in FIG. Figure 4 As shown, the controller controls the rotating arm rotation driving component 25 to drive the rotating arm 22 to rotate clockwise so that the axis of the hinge shaft I 221 passes the hinge dead point position between the force limiting compensation mechanism 23 and the rotating arm 22, and the rotating arm 22 is limited against the limit block 26. At the same time, the rotating arm 22 drives the flipping tank holding claw 24 to rotate clockwise around the axis of the hinge shaft III 242 through the force limiting compensation mechanism 23, so that the claw structure of the flipping tank holding claw 24 rotates clockwise and flips out to be carried on the bottom of the tank cage 4, completing the tank holding action. At this time, since the axis of the hinge shaft I 221 is located above the hinge dead point position between the force limiting compensation mechanism 23 and the rotating arm 22, the load transmitted from the tank cage 4 can be sequentially transmitted through the flipping tank holding claw 24, the force limiting compensation mechanism 23, and the flipping tank holding claw 24. The compensation mechanism 23, the rotating arm 22 and the support seat 21 act on the mobile frame 12, and under the rigid support of the rotating arm 22, the support seat 21 and the mobile frame 12, the kinetic energy of the variable load transmitted by the tank cage 4 can be absorbed by the force-limited compensation mechanism 23, that is, the buffer rod 233 and the compression spring plate 231 act on the compression spring 232, and by selecting the compression spring 232 whose elastic force does not exceed the squatting tank limit, the kinetic energy of the variable load can be absorbed by the compression spring 232; the kinetic energy of the variable load transmitted by the tank cage 4 can also be absorbed by the sliding guide driving component 13, thereby realizing two-stage buffering, thereby realizing the stable tank operation with limited freedom of the lower direction of the tank cage 4 and ensuring the stable entry and exit of the tank cage 4 in the mine car;

[0033] After the operation of entering and exiting the mine car is completed, when the cage 4 needs to be lifted or lowered, the controller first starts the tank claw flip control circuit to perform a reset operation, such as Figure 6 As shown, the controller controls the rotating arm rotation driving component 25 to drive the rotating arm 22 to rotate counterclockwise, and the rotating arm 22 drives the flipping tank holding claw 24 to rotate counterclockwise around the axis of the hinge shaft III 242 through the force limiting compensation mechanism 23, and the claw structure of the flipping tank holding claw 24 rotates counterclockwise and flips in to make way for the bottom end of the tank cage 4; then the controller starts the sliding control circuit of the mobile frame to perform a reset operation, and the controller controls the sliding guide driving component 13 to make the mobile frame 12 slide backward and retract. In the process of the mobile frame 12 moving backward away from the tank cage 4, the linkage mechanism 32 drives the rocking table 31 to flip backward along the hinge center of the rocking table 31. After the mobile frame 12 moves backward to the initial position, the rocking table 31 is tilted, completing the rocking table making way action.

[0034] When the positioning inclined surface structure of the cage top against the clamping positioning arm 14 is in a clamping state against the chamfered vertical surface of the cage 4, the variable load generated by the upper and lower cages 4 of the mine car will cause the cage 4 to move up and down, thereby wearing the positioning inclined surface structure of the cage top against the clamping positioning arm 14 or the chamfered vertical surface of the cage 4. In order to reduce the wear, as a further improvement of the present invention, Figure 3 As shown, a guide roller 141 with a horizontally arranged rolling axis is provided on the positioning inclined surface structure of the cage top against the clamping positioning arm 14.

[0035] In order to achieve a more stable clamping effect of the cage 4 by the cage top clamping positioning arm 14, as a further improvement of the present invention, a plurality of guide rollers 141 are arranged along the upper and lower directions of the positioning inclined surface structure of the cage top clamping positioning arm 14.

[0036] In order to accurately control the sliding distance of the movable frame 12 in the front-rear direction so as to achieve a stable clamping of the tank cage 4, as a further improvement of the present invention, the sliding guide mechanism is provided with at least a forward limiting component which can limit the forward moving distance of the movable frame 12.

[0037] In order to accurately control the sliding distance of the mobile frame 12 in the front-to-back direction and to achieve a stable clamping of the cage 4, as a further improvement of the present invention, a distance sensor is provided at the position corresponding to the cage 4 on the mobile frame 12, and the distance sensor is electrically connected to the controller of the centralized electric control part. The distance sensor can be directly arranged on the front end surface of the mobile frame 12, or on the positioning inclined surface structure of the cage against the clamping positioning arm 14. During the forward movement of the mobile frame 12, the controller can accurately control the forward movement distance of the mobile frame 12 through the feedback of the distance sensor.

[0038] In order to achieve a more stable can supporting effect, as a further improvement of the present invention, Figure 3 As shown, the tank holding part 2 is arranged in multiple sets symmetrically with respect to the movable frame 12 .

[0039] In order to reduce the number of mechanical settings and achieve synchronous operation, as a further improvement of the present invention, Figure 3 As shown, a plurality of sets of can-carrying parts 2 share the same rotating arm rotation driving component 25 .

[0040] In order to facilitate adjusting the limited elastic force of the compression spring 232 according to the squatting tank limit, as a further improvement scheme of the present invention, as follows Figure 5 As shown, the buffer rod 233 is a screw structure, and a force adjusting nut 235 is provided on the screw structure to cooperate with its thread. The compression spring plate 231 is slidably fitted on the buffer rod 233. The position of the compression spring plate 231 is adjusted by adjusting the force adjusting nut 235, thereby adjusting the limited elastic force of the compression spring 232.

[0041] The tank stabilizing and compensating cradle of the present vertical shaft hoisting wire rope way can realize the large movement of the mobile frame 12 towards or away from the cage 4 by controlling the sliding guide driving component 13, and then, on the premise of meeting the requirement of a minimum gap of 350mm between the most protruding part of the cage and the shaft wall and the shaft beam, the structural dimensions of the flipping tank supporting claw 24 can be greatly reduced, so that the overall structure of the tank stabilizing and compensating cradle can be flattened and easy to install; the tank stabilizing operation with limited freedom of the cage 4 in five directions can be realized, and the stability of the cage 4 in and out of the mine car can be ensured; the variable load kinetic energy transmitted by the cage 4 can be absorbed by the force limiting compensation mechanism 23 on the one hand, and by the sliding guide driving component 13 on the other hand, so that not only a larger buffer stroke can be obtained, but also multi-level buffering can be realized, thereby achieving a better tank stabilizing effect, which is particularly suitable for the wire rope way of medium and deep mines.
