Specific embodiments

[0031] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Each example is provided by way of explanation of the present application rather than a limitation of the present application. In fact, those skilled in the art will clearly understand that modifications and variations can be made to the present application without departing from the scope or spirit of the present application. For example, features shown or described as part of one embodiment can be used in another embodiment to yield yet another embodiment. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention shall fall within the scope of protection of the embodiments of the present invention.

[0032] Currently, during the support process of the internal leakage type single hydraulic prop used for roadway support, usually, an operator uses tools to manually operate the ascending drive cylinder of the single hydraulic prop or press the descending switch to achieve the lifting and lowering actions of the single hydraulic prop; and as the mining face continuously moves forward, the single hydraulic prop also needs to be carried, transferred, lifted, and lowered differently with the mining face, and currently these operations are all completed manually by workers, with extremely high labor intensity, and there are inevitable safety hazards to workers during the manual operation process.

[0033] Based on this, the embodiments of the present application provide a single hydraulic prop lifting driver to replace manual labor to achieve automatic driving of the internal leakage type single hydraulic prop 100, enabling the single hydraulic prop 100 to be automatically lifted and lowered, as Figures 1 to 6 shown, the single hydraulic prop lifting driver includes: a fixed clamping seat 200, an ascending drive module 300, and a descending drive module 400. Among them, the fixed clamping seat 200 is detachably installed on the single hydraulic prop 100, the ascending drive module 300 and the descending drive module 400 are installed inside the housing structure of the fixed clamping seat 200, the ascending drive module 300 is used to drive the ascending drive pump of the single hydraulic prop 100 to act, and the descending drive module 400 is used to control the opening and closing of the descending switch 102 of the single hydraulic prop 100.

[0034] In a specific example, a loading base is provided on the first housing of the fixed clamping seat 200. The loading base is connected to the outer shell of the power input end 101 of the ascending drive pump of the single hydraulic prop 100, further enhancing the connection stability between the fixed clamping seat 200 and the single hydraulic prop 100. An ascending drive module 300 is installed in the first housing. The output end with a special-shaped cross-section of the ascending drive module 300 is installed on the first housing through a bearing and is connected to the power input end 101 of the ascending drive pump after passing through the loading base, for driving the ascending drive pump to act. Here, it should be noted that the output end with a special-shaped cross-section matches the power input end 101 of the ascending drive pump. When the power input end 101 of the ascending drive pump is rectangular, triangular, etc., the output end with a special-shaped cross-section is a corresponding rectangular hole, triangular hole, etc.

[0035] Specifically, the first housing includes a rectangular housing 201 with an open front end and a closed rear end and a cover plate. The cover plate and the rectangular housing 201 are connected by bolts to close the front opening of the rectangular housing 201. The loading base is arranged on the bottom plate of the rectangular housing 201 and is provided with an insertion through hole facing the input end of the ascending drive pump. Thereby, the outer shell of the power input end 101 of the ascending drive pump is inserted and connected into the insertion through hole.

[0036] An F-shaped fixing buckle 203 is further arranged on the bottom plate of the rectangular housing 201. The upper opening of the F-shaped fixing buckle 203 is a semi-circular structure adapted to the outer side wall of the single hydraulic prop 100. During the process of fixedly connecting the fixed clamping seat 200 to the single hydraulic prop 100, the fixed clamping seat 200 is tightly held on the single hydraulic prop 100 through a semi-circular hoop 204 adapted to the F-shaped fixing buckle 203. Among them, the semi-circular hoop 204 and the F-shaped fixing buckle 203 are connected by bolt fasteners to detachably install the fixed clamping seat 200 on the single hydraulic prop 100. Here, the F-shaped fixing buckle 203 and the rectangular housing 201 can be integrally formed, or the F-shaped fixing buckle 203 can be connected to the bottom plate of the rectangular housing 201 by bolt fasteners. Thereby, the connection to single hydraulic props 100 of different sizes can be achieved by replacing F-shaped fixing buckles 203 of different sizes.

[0037] In this application, in the ascending drive module 300, the ascending drive motor drives the rotation of the output end with a special-shaped cross-section through a gear transmission. Specifically, the ascending drive motor is installed on the outer side of the bottom plate of the rectangular housing 201 through a fastener. The output end of the ascending drive motor passes through the bottom plate of the rectangular housing 201 and extends into the rectangular housing 201, and is connected with a main drive gear 301. Inside the rectangular housing 201, the driven wheel 302 that meshes with the main drive gear 301 through gears is rotatably installed on the bottom plate of the rectangular housing 201. Through the gear meshing of the main drive gear 301 and the driven wheel 302, the output power of the ascending drive motor is transmitted to the output end with a special-shaped cross-section. Furthermore, through the continuous movement of the output end with a special-shaped cross-section, the ascending drive pump is driven to operate, realizing the ascending of the single hydraulic prop 100.

[0038] In a specific example, the driven wheel 302 drives the rotation of the output end with a special-shaped cross-section through a crank connecting rod mechanism 303. Among them, the crank of the crank connecting rod mechanism 303 is fixedly connected to the output end with a special-shaped cross-section, and the connecting rod of the crank connecting rod mechanism 303 is eccentrically connected to the driven wheel 302. Thus, the rotation of the driven wheel 302 drives the connecting rod to perform a circular motion around the center of the driven wheel 302, and the connecting rod drives the output end with a special-shaped cross-section to rotate, transmitting the power to the output end with a special-shaped cross-section.

[0039] Here, the output end with a special-shaped cross-section is rotatably installed on the bottom plate and the cover plate of the first housing through bearings. Specifically, on the bottom plate of the rectangular housing 201, an installation counterbore is coaxially arranged with the insertion through hole, and the bearing is installed in the installation counterbore. The cylindrical part of the output end with a special-shaped cross-section is connected to the inner ring of the bearing. Similarly, on the cover plate, a bearing is also installed in a similar structural form and is connected to the cylindrical part of the output end with a special-shaped cross-section.

[0040] In this application, a descending drive module 400 is installed in the second housing 202 of the fixed clamping seat 200. The output end 403 with a linear cross-section of the descending drive module 400 passes through the second housing 202 and contacts the descending switch 102 of the single hydraulic prop 100. The opening and closing of the descending switch 102 are realized through the rotation of the output end 403 with a linear cross-section. Specifically, when the linear cross-section rotates, through the contact between the output end 403 with a linear cross-section and the descending switch 102, the descending switch 102 will be forced to be pressed downward; when the output end 403 with a linear cross-section rotates in the reverse direction, the output end 403 with a linear cross-section has a tendency to disengage from the descending switch 102, and the descending switch 102 automatically bounces upward. Here, the second housing 202 is detachably installed on the side of the first housing through bolt fasteners. Specifically, it is detachably installed on the side plate of the rectangular housing 201 through a connecting ear plate and corresponds to the descending switch 102 of the single hydraulic prop 100.

[0041] In the lowering drive module 400 installed within the second housing 202, the output end of the lowering drive motor 401 installed within the second housing 202 drives the rotation of the output end 403 with a rectangular cross-section through a worm and worm gear mechanism 402. Among them, the output end of the lowering drive motor 401 is connected to the worm of the worm and worm gear mechanism 402. The worm gear of the worm and worm gear mechanism 402 is rotatably installed within the second housing 202 and is coaxially connected to the output end 403 with a rectangular cross-section. Here, the worm gear and the output end 403 with a rectangular cross-section can be an integrally formed structure or a split connection (such as insertion, snap connection, etc.). The two ends of the worm gear are respectively rotatably installed on the second housing 202 through bearings. The cylindrical part of the output end 403 with a rectangular cross-section is coaxially connected to the worm gear, and the rectangular part is inserted into the jack of the lowering switch 102 on the single hydraulic prop 100 and contacts the lowering switch 102. Furthermore, the rotation of the lowering drive motor 401 drives the rotation of the output end 403 with a rectangular cross-section, prompting the opening and closing of the lowering switch 102, thereby realizing the lowering action of the single hydraulic prop 100.

[0042] In the embodiment of the present application, the lowering drive motor 401 and the raising drive motor can be powered by an external power source. Additionally, a power module can be correspondingly installed on the fixed housing to supply electrical energy to the lowering drive motor 401 and the raising drive motor. The power module can be charged using an external charging unit or a hand-cranked charging unit. Moreover, control buttons can be provided on the cover plate to achieve the opening and closing control of the raising drive motor and the lowering drive motor 401. Further, remote control of the raising drive motor and the lowering drive motor 401 can be realized through wireless communication, and a corresponding alarm system can be installed to emit a warning signal when the single hydraulic prop 100 is operating to warn the surrounding personnel.

[0043] During use, after moving the single hydraulic prop 100 to the support position, a control command can be issued through the human-machine interaction controller to start the raising drive motor, drive the action of the output end with a special cross-section, drive the raising drive pump to act, and drive the single hydraulic prop 100 to rise. When it is necessary to remove the single hydraulic prop 100, a lowering command is issued through the human-machine interaction controller to start the lowering drive motor 401, drive the action of the output end 403 with a rectangular cross-section, open the lowering switch 102, and enable the single hydraulic prop 100 to be lowered and recovered. Thus, through the raising drive module 300 and the lowering drive module 400, the automatic control of the raising and lowering of the internal leakage type single hydraulic prop 100 is realized, replacing manual operation, greatly reducing the labor intensity, improving the work efficiency, and having a positive significance for promoting the automation and intelligence of the single hydraulic prop 100.
