Description

Technical Field

[0001] This application relates to the field of mine shaft hoisting technology, and in particular to an adaptive rapid can-lifting and locking device. Background Technology

[0002] Currently, vertical shaft cages remain the primary equipment for lowering equipment and materials in underground mines. With the widespread adoption of mechanized mining methods, the frequency of lowering overweight materials using cages is increasing. When lowering heavy objects, the steel cable above the cage experiences a sudden stretching force upon the object's entry into the cage, causing the cage to drop rapidly and interfering with the smooth entry of the object. After the object leaves the cage, the steel cable quickly contracts and rebounds, causing the cage to move rapidly upwards in the shaft. This not only makes it difficult for equipment to leave the cage but can also lead to cage jamming accidents, posing significant safety hazards. Therefore, during the loading and unloading of heavy objects, the cage must be supported and locked to ensure its height remains constant and to prevent the deformation and stretching of the steel cable from affecting the entry and exit of heavy objects.

[0003] Currently, most vertical shaft cages still use hand-operated hoists for cage support and locking. Personnel pre-fix the hoists to the two steel cage guide beams closest to the top and bottom of the cage. Once the cage reaches the loading / unloading position, the hoists are manually connected to the cage, and tensioning is adjusted to secure and lock the cage. However, this method is time-consuming, labor-intensive, and carries significant risks. Although existing technologies include devices for rapid cage stabilization and locking, such as the rapid cage stabilization and locking device disclosed in Chinese Patent 202320641737.6, [further details omitted]. Figure 7 As shown, the device includes a cage, a limiting block, a shaft steel beam, a cage locking mechanism, a slot, a base, a pin, and a support rod. The support rod supports the limiting block to complete the cage locking operation. However, this device uses a lever support principle to lock and unlock the cage 1, which has problems such as a small contact surface of the limiting block, difficulty in installation, limited load-bearing capacity, and lack of self-adaptation.

[0024] To address the aforementioned issues, this application provides an adaptive rapid can-holding and locking device. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 , Figure 2and Figure 3 An adaptive rapid can-lifting and locking device is shown, comprising a support beam 3 and a can-locking clamp 2. The support beam 3 is welded and fixedly installed on the steel can guideway of the well shaft, facing the can cage 1. The can-locking clamp 2 is as follows: Figure 6 As shown, four support beams 3 are set up and installed in sets on the same horizontal level at the loading and unloading gates of each vertical shaft, and the lock clamp 2 clamps the cage partition 4. The lock can clamp 2 includes: a thin clamping plate 202, a pressure plate 203, bushing I 204, bushing II 205, a pin 207, a shaft 208, and bushing III 209. A positioning bushing III209 is provided at the center of shaft 208. Bushings I204 and II205 are connected to both ends of bushing III209. At least five thin clamping plates 202 are connected to bushings II205 and I204 respectively. At least two positioning grooves are constructed on the thin clamping plates 202. Pressure plates 203 are fixedly provided at both ends of shaft 208. At least two through holes are constructed on the pressure plates 203 corresponding to the positioning grooves of the thin clamping plates 202. A pin 207 is inserted between the two pressure plates 203.

[0026] In this application, a support beam 3 is installed on the steel tank passage at the entrance of the loading and unloading section, and a lock clamp 2 is installed on the support beam 3. The lock clamp 2 can be directly welded to the support beam 3 as needed, or connected through a bracket, or connected to the support beam 3 through any other connection method that does not affect the operation. Based on the loading / unloading status and weight of cage 1, personnel only need to stand inside cage 1 and rotate the clamps on the locking clamp 2 to ensure that the clamps firmly hold the cage partition 4. Then, they are fixed with pins 207. The force on cage 1 during loading and unloading is distributed to the shaft steel cage track through the locking clamp 2 and support beam 3, thereby locking the cage and achieving the purpose of quickly lifting and locking the cage. This effectively avoids the problem of the cage moving down or up instantly due to the deformation and expansion of the wire rope during loading and unloading. It has a large load-bearing capacity and high locking stability. At the same time, since the number of clamps can be adjusted, the locking height of the cage can also be adjusted. It is convenient, quick, and simple in structure. Compared with the manual hoisting method of stabilizing the cage, it can significantly reduce personnel safety risks and labor intensity.

[0027] In this application, when a heavy object needs to be loaded into the cage 1, the cage 1 is controlled to move to the target yard elevation and stop. At the same time, the lower half of the clamps in the four locking clamps 2 are rotated 90° sequentially from bottom to top towards the bottom of the cage partition 4 on the side of the cage 1 until no clamp can rotate. The force on the clamps is observed. At this time, the clamps are completely pressed against the bottom of the cage partition 4. The four locking clamps 2 restrict the cage 1 from moving downward during the loading of the heavy object. When a heavy object needs to be pushed away from the cage 1, the cage 1 is controlled to move to the target yard elevation and stop. At the same time, the upper half of the clamps in the four locking clamps 2 are rotated 90° sequentially from top to bottom towards the top of the cage partition 4 on the side of the cage 1 until no clamp can rotate. The force on the clamps is observed. At this time, the clamps are completely pressed against the top of the cage partition 4. The four locking clamps 2 restrict the cage 1 from moving upward during the pushing away of the heavy object.

[0028] This invention utilizes a support beam on the steel cage guideway in the shaft and a cage-locking clamp mounted on the support beam. The cage-locking clamp consists of clamping plates, pressure plates, bushings, stiffening plates, pins, and shafts. Two positioning holes are pre-drilled on the pressure plate, and two slots are pre-drilled on the bushing side of the clamping plate to ensure the pressure plate remains stationary during cage locking / unlocking. Depending on the loading / unloading status and weight of the cage, personnel only need to rotate the pressure plate and clamping plates on the cage-locking clamp inside the cage and fix them with pins. The force exerted on the cage during loading and unloading is distributed to the steel cage guideway in the shaft through the cage-locking clamp and support beam, achieving cage locking and thus quickly lifting and locking the cage. This effectively avoids the problem of the cage shifting instantaneously downwards or upwards due to the deformation and expansion of the wire rope during loading and unloading. It has a large load-bearing capacity and high cage-locking stability. Furthermore, because the number of clamping plates is adjustable, the cage-locking height can also be adjusted, making it convenient, quick, and simple in structure. Compared to manual chain hoists for cage stabilization, it significantly reduces personnel safety risks and labor intensity.

[0029] In one embodiment, such as Figure 3 and Figure 4 and Figure 5 As shown, in order to facilitate clamping and securing the cage partition 4 and provide support strength, a thick clamping plate 201 is transferred to the bushing I204 on one side. A right-angled triangular rib plate 206 is vertically arranged on one side of the thick clamping plate 201. The thick clamping plate 201 also has two positioning grooves in the same position as the thin clamping plate 202.

[0030] In one embodiment, the two positioning slots are arranged at a 90-degree angle, which facilitates positioning and adjustment.

[0031] In one embodiment, the rotation angle of the thick clamping plate 201 and the thin clamping plate 202 is not less than 90 degrees, which facilitates the rotation adjustment of the clamping plates. The angle is preferably matched with the angle of the positioning groove for easy fixing.

[0032] In one embodiment, the manual insertion and insertion of the pin 207 still requires manual intervention. To improve work efficiency and reduce the risk of fixture failure, the pin 207 is replaced by an electrically telescopic pin, replacing the manual insertion and removal of the pin. To adapt to the normal insertion and removal of the pin after automatic modification, the electrically telescopic pin includes an electrically telescopic rod and a positioning rod. The positioning rod is fixedly set between the two pressure plates 203, and the positioning rod does not affect the rotation of the thick clamping plate 201 and the thin clamping plate 202. Specifically, the edge of the positioning rod is slightly away from the rotation edge of the clamping plate. The telescopic end of the electrically telescopic rod is hollow and is slidably mounted on the positioning rod, and the telescopic end of the electrically telescopic rod can lock into the positioning grooves on the thick clamping plate 201 and the thin clamping plate 202.

[0033] In one embodiment, to enable mechanical adjustment of the clamping plates instead of manual adjustment, this application further includes an automatic rotation mechanism 5. This automatic rotation mechanism is located on one side of the lock clamp 2 to drive the thick clamping plate 201 and the thin clamping plate 202 of the lock clamp 2 to rotate at a certain angle. Specifically, as shown... Figure 8 As shown, the automatic rotating mechanism 5 includes a rotating motor 51, a rotating disk 52, a rotating arm 53, and a rotating pallet 54; The rotary motor 51 is mounted on the support beam 3 via a bracket. A rotating disk 52 is connected to the output shaft of the rotary motor 51. An arc-shaped rotating arm 53 is connected to one side of the rotating disk 52, and a rotating support plate 54 is attached to one end of the rotating arm 53. In this way, by controlling the rotation of the motor, the rotating arm 53 is driven to rotate the clamping plate, while the rotating support plate 54 is equivalent to the hand that is turning the plate, facilitating the overall rotation.

[0034] In one embodiment, because there are multiple clamping plates, some clamping plates may remain unmoved during the actual actuation process. Therefore, the automatic rotation mechanism 5 needs to be adjusted in real time. This application uses a bracket to adjustably slide the rotary motor 51 onto the support beam 3, and its adjustment is achieved by pulling with an electric telescopic rod. The rotating support plate 54 is provided with a pivot seat 55, and the rotating arm 53 is rotatably connected to the rotating support plate 54 via a pivot. The rotating support plate 54 abuts against the thick clamping plate 201 and the thin clamping plate 202. In this way, the position of one of its moving axes can be adjusted by pulling the rotary motor 51 on the bracket with the electric telescopic rod to adapt to the number of clamping plates that need to be actuated. Then, the operation of the rotary motor 51 actuates the adjusted clamping plates to achieve secure clamping of the cage partition 4.

[0035] In one embodiment, to facilitate the automatic return of the clamping plates, a torsion spring is provided on the thick clamping plate 201 and each thin clamping plate 202 for automatic return.

[0036] In this application, when a heavy object needs to be loaded into the cage 1, the cage 1 is controlled to move to the target yard elevation and stop. At the same time, the lower half of the clamps in the four locking clamps 2 are rotated 90° sequentially from bottom to top towards the bottom of the cage partition 4 on the side of the cage 1 until no clamp can rotate. The force on the clamps is observed. At this time, the clamps are completely pressed against the bottom of the cage partition 4. The four locking clamps 2 restrict the cage 1 from moving downward during the loading of the heavy object. When a heavy object needs to be pushed away from the cage 1, the cage 1 is controlled to move to the target yard elevation and stop. At the same time, the upper half of the clamps in the four locking clamps 2 are rotated 90° sequentially from top to bottom towards the top of the cage partition 4 on the side of the cage 1 until no clamp can rotate. The force on the clamps is observed. At this time, the clamps are completely pressed against the top of the cage partition 4. The four locking clamps 2 restrict the cage 1 from moving upward during the pushing away of the heavy object.

[0037] This invention utilizes a support beam on the steel cage guideway in the shaft and a cage-locking clamp mounted on the support beam. The cage-locking clamp consists of clamping plates, pressure plates, bushings, stiffening plates, pins, and shafts. Two positioning holes are pre-drilled on the pressure plate, and two slots are pre-drilled on the bushing side of the clamping plate to ensure the pressure plate remains stationary during cage locking / unlocking. Depending on the loading / unloading status and weight of the cage, personnel only need to rotate the pressure plate and clamping plates on the cage-locking clamp inside the cage and fix them with pins. The force exerted on the cage during loading and unloading is distributed to the steel cage guideway in the shaft through the cage-locking clamp and support beam, achieving cage locking and thus quickly lifting and locking the cage. This effectively avoids the problem of the cage shifting instantaneously downwards or upwards due to the deformation and expansion of the wire rope during loading and unloading. It has a large load-bearing capacity and high cage-locking stability. Furthermore, because the number of clamping plates is adjustable, the cage-locking height can also be adjusted, making it convenient, quick, and simple in structure. Compared to manual chain hoists for cage stabilization, it significantly reduces personnel safety risks and labor intensity.
