Description

Technical Field

[0001] This invention relates to the field of bracket installation, specifically a hydraulic bracket installation and positioning device with a locking and pushing mechanism. Background Technology

[0002] With the gradual improvement of coal mine safety production management standards, the safe and convenient installation of advanced hydraulic support supports for roadways has become a key factor affecting underground safety production. Various types of hydraulic support installation devices are developing towards lightweighting, automation, and intelligence.

[0003] To address the installation requirements of advanced support supports in fully mechanized mining faces, several hydraulic support relocation devices have emerged on the market, with the device publicly disclosed by Liaoning Weiyue Group being the most representative. This hydraulic support relocation device has a lifting arm on each side of the platform, with a turntable in the center connected to the platform via an axle. The assembled hydraulic support is transferred by a loading mechanism to the hydraulic support relocation device and transported to the installation location. The turntable then lifts, rotates, and pushes the support, which is then installed in the designated position by forks. While this device solves the transportation and steering of hydraulic supports to some extent, its complex turntable structure, the need for a certain height for steering, and unreliable locking of the hydraulic support make it prone to swaying during lifting due to insufficient flatness of the working face, potentially leading to safety accidents. Summary of the Invention

[0004] To achieve the above objectives, the present invention aims to provide a hydraulic support installation and positioning device with a locking and pushing mechanism, which can solve the problems existing in the prior art. The present invention provides the following technical solution:

[0005] A hydraulic support installation and positioning device with a locking and pushing mechanism includes a sliding platform, a locking mechanism, a support steering mechanism, and an emulsion motor. The locking mechanism, support steering mechanism, and emulsion motor are all mounted on the sliding platform. The locking mechanism includes a fixed rail and a chain hook adapted to the fixed rail. The chain hook is connected to the emulsion motor, and a support locking and fixing ring is also connected to the chain hook. The support steering mechanism includes a support, a pushing cylinder, a fixed rotating seat, a fixed rotating shaft, and a movable rail. The fixed rotating seat and fixed rotating shaft are both mounted on the fixed rail, and a rotating arm is mounted on the movable rail. The sliding platform ensures that the hydraulic support can slide and steer stably on it. The hydraulic support is locked to the sliding platform by the support locking and fixing ring in the fixed rail. When the hydraulic support is transported to the sliding platform, this device can lock the hydraulic support in the fixed rail at the fixed rotating seat and fixed rotating shaft, ensuring the safety and reliability of the entire hydraulic support adjustment process. The guiding mechanism is primarily achieved through a fixed track and a chain hook drive device. The fixed track is specifically designed according to a predetermined turning and traveling trajectory to guide the hydraulic support along the prescribed path. The support turning mechanism rotates the hydraulic support 90 degrees around the fixed pivot point via a hydraulic operating lever. This allows for safe and convenient movement of the hydraulic support to its installation position without lifting it, significantly improving the safety and convenience of downhole hydraulic support relocation operations. The working process of this device is as follows: The tail of the hydraulic support is hoisted onto the inclined surface of the sliding platform using a monorail (simply stepping onto the inclined surface is sufficient). The support locking ring is connected and locked to the hydraulic support hoisting hole. The emulsion motor is started, driving the chain hook in the locking mechanism. This, combined with the support locking ring on the chain hook, transports the hydraulic support to the sliding platform. After the locking mechanism has moved the hydraulic support to the designated position at the front edge of the sliding platform, the support turning mechanism is activated, rotating the hydraulic support 90 degrees and adjusting it from longitudinal to lateral. Then, the pusher column is inserted into the middle hole of the telescopic shoe. The telescopic shoe cylinder is operated to push the hydraulic support onto the fixed shoe and completely detach it from the sliding platform. The telescopic shoe is then retracted to its original position. Finally, the pull-push column is inserted into the front hole of the telescopic shoe. The telescopic shoe cylinder is operated to extend the telescopic shoe, and the pull-push column presses firmly against the hydraulic support, causing the entire sliding platform to move backward 1.6 meters. At the same time, the hydraulic support detaches from the fixed shoe and falls to the ground, thus completing one hydraulic support installation process. This method of hydraulic support relocation avoids the risk of falling due to undulating terrain at the fully mechanized mining face during the relocation of the hydraulic support.

[0006] As a further aspect of the present invention: the sliding platform includes a first platform, a second platform, a third platform, a fourth platform, a fifth platform, a sixth platform, and a seventh platform connected in sequence.

[0007] As a further aspect of the present invention: both the support and the pushing cylinder are mounted on the seventh platform, which facilitates the adjustment of the hydraulic support.

[0008] As a further embodiment of the present invention: a fixed track passes through the second platform, the third platform, the fourth platform and the fifth platform in sequence, and a movable track is installed in the fifth platform and connected to the fixed track.

[0009] As a further aspect of the present invention, the fourth platform and the fifth platform are connected by a hinge, which facilitates the setting of fixed and movable tracks.

[0010] As a further aspect of the present invention, reinforcing plates are installed at the fixed rotating base and the fixed rotating shaft to increase the load-bearing capacity, seismic performance and overall stability of the fixed rotating base and the fixed rotating shaft, thereby ensuring the stability of the hydraulic support during the adjustment process.

[0011] As a further aspect of the present invention: the emulsion motor is connected to the chain hook through a combination of a driving wheel and a driven wheel, resulting in good transmission stability.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The locking mechanism in this product securely and firmly locks the hydraulic support to the sliding platform and the fixed pivot, ensuring that the hydraulic support remains close to the working surface of the sliding platform throughout the entire process of adjustment, turning, and transportation. This effectively avoids a series of safety hazards caused by lifting the hydraulic support. Furthermore, the entire system is hydraulically driven, requiring no manual intervention, greatly reducing the labor intensity of workers. Workers only need to gently push the hydraulic control lever to complete the installation and positioning of the hydraulic support. Attached Figure Description

[0020] Example 1

[0021] See Figure 1-3A hydraulic support installation and positioning device with a locking and pushing mechanism includes a sliding platform, a locking mechanism, a support steering mechanism, and an emulsion motor. The locking mechanism, support steering mechanism, and emulsion motor are all mounted on the sliding platform. The locking mechanism includes a fixed rail 11 and a chain hook adapted to the fixed rail 11. The chain hook is connected to the emulsion motor, and a support locking and fixing pull ring is also connected to the chain hook. The support steering mechanism includes a support 8, a pushing cylinder 9, a fixed rotating seat 12, a fixed rotating shaft 13, and a movable rail 14. The fixed rotating seat 12 and the fixed rotating shaft 13 are both mounted on the fixed rail 11, and a rotating arm is mounted on the movable rail 14. The sliding platform ensures that the hydraulic support can slide and steer stably on it. The hydraulic support is locked to the sliding platform by the support locking and fixing pull ring in the fixed rail 11. When the hydraulic support is transported to the sliding platform, this device can lock the hydraulic support in the fixed rail 11 at the fixed rotating seat 12 and the fixed rotating shaft 13, ensuring the safety and reliability of the entire hydraulic support adjustment process. The guiding mechanism is primarily achieved through a fixed track 11 and a chain hook drive device (i.e., an emulsion motor). The fixed track 11 is specifically designed according to a predetermined turning and traveling trajectory to guide the hydraulic support along the prescribed path. The support turning mechanism rotates the hydraulic support 90 degrees around the fixed pivot 13 via a hydraulic operating lever. This allows the hydraulic support to be safely and conveniently moved to its installation position without lifting it, greatly improving the safety and convenience of downhole hydraulic support relocation operations. The working process of this device is as follows: The tail of the hydraulic support is hoisted onto the inclined surface of the sliding platform using a monorail (simply stepping onto the inclined surface is sufficient). The support locking and fixing ring is connected to and locked with the hydraulic support hoisting hole. The emulsion motor is started, thereby driving the chain hook in the locking mechanism to move. In conjunction with the support locking and fixing ring on the chain hook, the hydraulic support is transported as a whole to the sliding platform. After the locking mechanism drags the hydraulic support to the predetermined position at the front edge of the sliding platform... Activate the support steering mechanism to rotate the hydraulic support 90 degrees, adjusting it from longitudinal to lateral. Then, insert the push column into the middle hole of the telescopic shoe, operate the telescopic shoe cylinder to push the hydraulic support onto the fixed shoe and completely detach it from the sliding platform, then retract the telescopic shoe to its original position. Finally, insert the pull-push column into the front hole of the telescopic shoe, operate the telescopic shoe cylinder to extend the shoe, and pull-push the column tightly against the hydraulic support, causing the entire sliding platform to move backward 1.6 meters. Simultaneously, the hydraulic support detaches from the fixed shoe and falls to the ground, completing one hydraulic support installation process. This method of hydraulic support relocation avoids the risk of falling due to undulating terrain at the fully mechanized mining face during the relocation process.

[0022] In one embodiment of the present invention, the sliding platform includes a first platform 1, a second platform 2, a third platform 3, a fourth platform 4, a fifth platform 5, a sixth platform 6, and a seventh platform 7 connected in sequence.

[0023] In one embodiment of the present invention, a reinforcing plate 15 is installed at the fixed rotating base 12 and the fixed rotating shaft 13 to increase the load-bearing capacity, seismic performance and overall stability of the fixed rotating base 12 and the fixed rotating shaft 13, and to ensure the stability of the hydraulic support during the adjustment process.

[0024] In one embodiment of the present invention, the emulsion motor is connected to the chain hook through a combination of a driving wheel and a driven wheel, resulting in good transmission stability.

Furthermore, the hinge 10 is a ball joint, which is low in cost, easy to purchase, and has good performance.
