Description

Technical Field

[0001] This utility model relates to the field of hydraulic equipment technology, specifically to a hydraulic support base and a hydraulic support. Background Technology

[0002] Hydraulic supports are the core support equipment in fully mechanized coal mining faces, their function being to effectively control mine pressure. During coal mining, mine pressure acts directly on the hydraulic supports as external loads. The hydraulic supports and the surrounding rock of the working face together form an interacting mechanical system. When the resultant force generated by the various supporting components of the support is aligned with the resultant force of the external load applied by the roof, it indicates that the hydraulic support has a high degree of adaptability to the current surrounding rock conditions. Therefore, hydraulic supports are widely used in mining engineering in the coal industry.

[0003] In existing technologies, to ensure hydraulic supports maintain a proper distance from other equipment when not in operation (such as during maintenance, storage, or transportation) and to provide maintenance space for operators, the hydraulic support is typically placed entirely on a support plate. Specifically, the bottom surface of the hydraulic support base abuts against the upper surface of the support plate, and then several bolts or other fasteners are used to fix one side of a limiting plate to the support plate, while the other side of the limiting plate abuts against the side wall of the hydraulic support base, thus limiting and fixing the hydraulic support base. However, this fixing method has significant drawbacks: the operation is cumbersome, and installing and removing the limiting plate is laborious and time-consuming; furthermore, frequent bolt removal and installation over a long period can easily lead to loosening or damage of the connection points, seriously affecting the stability and reliability of the limiting plate after installation. Especially during subsequent movement of the hydraulic support, the uneven ground in the well or construction site inevitably causes bumps during movement. If the limiting plate's constraint on the base is insufficient or loose, the hydraulic support is prone to shaking or even displacement during movement. Frequent bumps and impacts can cause the hydraulic support to slip off the support plate and fall off, which will not only cause serious damage to the hydraulic support itself, but may also endanger the safety of on-site personnel, posing a major safety hazard. Therefore, this utility model proposes a hydraulic support base and a hydraulic support to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic support base and a hydraulic support to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic support base and a hydraulic support, comprising: a hydraulic support base body, the lower surface of the hydraulic support base body abutting against the center surface of the upper surface of the base plate, support components being provided at the four corners of the base plate, the lower surface of the base plate being bolted to the wheel frame of the load-bearing wheel around its perimeter, and limit mechanisms being provided on both sides of the hydraulic support base body;

[0006] The limiting mechanism includes a limiting block that can be flipped in a horizontal and vertical state. A limiting rod that can slide within the limiting block is slidably fitted inside the limiting block. One end of the limiting rod is fixedly connected to an anti-slip protrusion, and the other end of the limiting rod is connected to a first driving component for driving the limiting rod to slide within the limiting block. The limiting block is slidably installed in the limiting frame. A second driving component for driving the limiting block to flip in a horizontal and vertical state is provided on one side of the limiting frame. The bottom of the limiting frame is fixedly connected to the upper surface of the base plate.

[0007] Preferably, the support assembly includes four support rods, all of which are threaded onto the four corners of the base plate, and the bottom ends of all four support rods are fixedly connected to the anti-slip feet.

[0008] Preferably, the first drive component includes a synchronous motor, which is fixedly mounted on the top of the U-shaped frame, and the bottom of the U-shaped frame is fixedly connected to the limiting block. A threaded rod is rotatably mounted between the U-shaped frame and the limiting block.

[0009] Preferably, the threaded rod is threadedly connected to the middle of the connecting plate, both ends of the connecting plate are fixedly connected to one end of the limiting rod, and the other end of the limiting rod is slidably sleeved in several limiting holes opened on the limiting block.

[0010] Preferably, the second drive assembly includes a handwheel, which is fixedly sleeved on one end of the worm, and the two sides of the worm are rotatably sleeved on the top of the fixed frame. The bottom of the fixed frame is fixedly connected to the upper surface of the base plate, and a worm wheel is engaged on the lower side of the worm, which is fixedly sleeved in the middle of the connecting shaft.

[0011] Preferably, both ends of the connecting shaft pass through the bottom of the fixed frame and are fixedly connected to one end of the rotating rod. The other end of the rotating rod is rotatably sleeved on one end of the connecting rod. The other end of the connecting rod is fixedly connected to the middle of the limiting block. Both ends of the limiting block are rotatably connected to the slider through limiting pins.

[0013] A hydraulic support includes the aforementioned hydraulic support base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a flip-out limit block and a sliding limit rod to work together with the drive component to achieve automated clamping, the fixing operation process of the hydraulic support base is significantly simplified, and the cumbersome process of traditional bolt disassembly and assembly is completely eliminated. At the same time, the rigid contact between the anti-slip protrusion and the limit rod forms a stable constraint, which effectively overcomes the risk of support displacement caused by transport bumps, and fundamentally avoids equipment damage and personnel injury accidents caused by the hydraulic support slipping.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a hydraulic support base and a hydraulic support, comprising: a hydraulic support base body 1, which supports the entire hydraulic support; the lower surface of the hydraulic support base body 1 abuts against the center surface of the upper surface of a base plate 2; the base plate 2 supports the entire hydraulic support and the hydraulic support base body 1; support components are provided at the four corners of the base plate 2, providing stable support for the base plate 2; the lower surface of the base plate 2 is bolted to the wheel frames of load-bearing wheels 3 around its perimeter; by installing the load-bearing wheels 3, the entire device can be easily transported; and limit mechanisms are provided on both sides of the hydraulic support base body 1 to limit... The positioning mechanism limits the hydraulic support base body 1 to ensure its stability during transportation. The positioning mechanism includes a positioning block 4 that can be flipped in a horizontal and vertical state. A positioning rod 5 that can slide within the positioning block 4 is slidably fitted inside the positioning block 4. One end of the positioning rod 5 is fixedly connected to an anti-slip protrusion 6, and the other end of the positioning rod 5 is connected to a first driving component for driving the positioning rod 5 to slide within the positioning block 4. The positioning block 4 is slidably installed in the positioning frame 7. A second driving component for driving the positioning block 4 to flip in a horizontal and vertical state is provided on one side of the positioning frame 7. The bottom of the positioning frame 7 is fixedly connected to the upper surface of the base plate 2.

[0023] In use, the entire base plate 2 is first stabilized by adjusting the support components. Then, the operator uses a crane or large forklift to place the hydraulic support on the upper surface of the base plate 2, so that the lower surface of the hydraulic support base body 1 abuts against the upper surface of the base plate 2. Then, driven by the second drive component, the limiting block 4 is rotated from a horizontal state to a vertical state under the limitation of the limiting frame 7. At this time, the limiting block 4 is parallel to the side wall of the hydraulic support base body 1. Then, driven by the second drive component, the limiting rod 5 moves towards the hydraulic support base body 1 under the limitation of the limiting block 4, until the limiting rod 5 drives the anti-slip protrusion 6 to contact the hydraulic support. The side walls of the hydraulic support base body 1 are tightly abutted, thereby limiting and fixing both sides of the hydraulic support base body 1. The friction is increased by the anti-slip protrusions 6, thereby ensuring the clamping force. Then, by adjusting the support components, the load-bearing wheels 3 support the base plate 2. Finally, by pushing the base plate 2 and cooperating with the rotation of the load-bearing wheels 3, the entire device is transported. At the same time, the limiting rod 5 and the anti-slip protrusions 6 limit and fix the hydraulic support and the hydraulic support base body 1, preventing the hydraulic support and the hydraulic support base body 1 from easily falling off the base plate 2 and causing personnel injury, which poses a high safety risk. This greatly improves the fixing strength of the hydraulic support base body 1.

[0024] The support assembly includes four support rods 8, each threadedly fitted onto the four corners of the base plate 2. A control box is fixedly installed at the center of the lower surface of the base plate 2. The bottom ends of the four support rods 8 are fixedly connected to anti-slip feet 9, and a turntable is fixedly fitted onto the top of each support rod 8. When the base plate 2 needs to be supported by the support rods 8, the turntable is twisted to rotate the support rods 8. This causes the support rods 8 to move downwards under the threaded connection between them and the base plate 2, until the support rods 8 drive the anti-slip feet 9 to contact the ground, thereby supporting the base plate 2 and the entire device.

[0025] The first drive assembly includes a synchronous motor 10, which is electrically connected to the control box. The synchronous motor 10 is fixedly mounted on the top of the U-shaped frame 11. The bottom of the U-shaped frame 11 is fixedly connected to the limiting block 4, which provides fixed support for the U-shaped frame 11. A threaded rod 12 is rotatably mounted between the U-shaped frame 11 and the limiting block 4. The threaded rod 12 is supported and limited by the U-shaped frame 11 and the limiting block 4. The threaded rod 12 is threadedly connected to the middle of the connecting plate 13. Both ends of the connecting plate 13 are fixedly connected to one end of the limiting rod 5. The other end of the limiting rod 5 is slidably fitted into several limiting holes 14 opened on the limiting block 4, which limit the limiting rod 5.

[0026] When the limiting block 4 flips from a horizontal state to a vertical state, the limiting block 4 is parallel to the side wall of the hydraulic support base body 1. At this time, the synchronous motor 10 is started by controlling the synchronous motor 10 to drive the threaded rod 12 to rotate. Under the rotation of the threaded rod 12, the connecting plate 13 is driven to move. The connecting plate 13 is limited by the cooperation of the limiting rod 5 and the limiting hole 14, so that the connecting plate 13 can move along the axis of the threaded rod 12. The connecting plate 13 then drives the limiting rod 5 to move synchronously, so that the limiting rod 5 drives the anti-slip protrusion 6 to move closer to the side wall of the hydraulic support base body 1 until the anti-slip protrusion 6 is tightly abutted against the side wall of the hydraulic support base body 1, thereby stably limiting the hydraulic support base body 1 on the base plate 2 and preventing it from shaking during transportation.

[0027] The second drive assembly includes a handwheel 15, which is fixedly sleeved on one end of a worm gear 16. Both sides of the worm gear 16 are rotatably sleeved on the top of a fixed frame 17. The bottom of the fixed frame 17 is fixedly connected to the upper surface of the base plate 2, providing limiting support for the worm gear 16. A worm wheel 18 meshes with the lower side of the worm gear 16, and the worm gear 16 engages with the worm wheel 18 for transmission. The worm wheel 18 is fixedly sleeved on the middle of a connecting shaft 19. Both ends of the connecting shaft 19 pass through the bottom of the fixed frame 17 and are fixedly connected to one end of a rotating rod 20. Both sides of the connecting shaft 19 are rotatably sleeved on the bottom of the fixed frame 17. The other end of the rotating rod 20 is rotatably sleeved on one end of the connecting rod 21. The other end of the connecting rod 21 is fixedly connected to the middle of the limiting block 4. The two ends of the limiting block 4 are rotatably connected to the slider 22 through the limiting pin. The slider 22 is slidably installed in the groove 23 opened on the inner side of the limiting frame 7. The slider 22 is set at both ends of the limiting block 4. The limiting block 4 at one end is in a horizontal state, and the limiting block 4 at the other end is in a vertical state. The limiting frame 7 has a groove 24 opened on the side near the fixed frame 17. The groove 24 is slidably connected to the connecting rod 21. The limiting frame 7 has an L-shaped design.

[0028] Initially, the limiting block 4 is horizontal. When it is necessary to limit and fix the hydraulic support base body 1, first turn the handwheel 15 to rotate the worm 16. The worm 16 meshes with the worm wheel 18, causing the worm wheel 18 to drive the connecting shaft 19 to rotate. The connecting shaft 19 then drives the rotating rod 20, which is fixedly connected to both ends, to rotate. The rotating rod 20 rotates towards the hydraulic support base body 1, thereby driving the limiting block 4 to move under the rotational connection of the connecting rod 21. The limiting block 4 is rotatedly connected to the slider 22 through the limiting pin, causing the horizontal slider 22 to slide horizontally. The slider 22 moves vertically, while the connecting rod 21 moves from the groove 24 at the bottom of the limiting frame 7 to the groove 24 at the top. Then the limiting block 4 flips from a horizontal state to a vertical state until the limiting block 4 is parallel to the side wall of the hydraulic support base body 1. Then the handwheel 15 is stopped, and the limiting rod 5 can be controlled to limit and fix the hydraulic support base body 1. The limiting block 4 provides stable support for the limiting rod 5, which further ensures the limiting stability of the hydraulic support base body 1. When it is necessary to release the limit, simply turn the handwheel 15 in the opposite direction.
