Description

Technical Field

[0001] This utility model relates to the field of hydraulic support technology, specifically to a hydraulic support base structure that is installed securely. Background Technology

[0002] Hydraulic supports are one of the main pieces of equipment in coal mining, playing a crucial supporting and protective role. The hydraulic support column is in direct contact with the top beam cap, and the pressure and impact force from the coal seam can be mainly distributed to the reinforcement and roof through the cap, thereby playing a role in stabilizing and supporting the roof.

[0003] Chinese patent CN221879432U discloses a stable hydraulic support base structure, relating to the field of hydraulic support technology. It includes a base plate with two bases fixedly mounted on it. Each base has a first mounting groove on one side of its upper end, within which two support seats are symmetrically fixed. A second mounting groove is also provided on the other side of the upper end of each base. A top rod is fixedly mounted on the base plate between the two bases. Multiple first locking tongue blocks and second locking tongue blocks are movably mounted on the base plate on one side of each base. Two second locking tongue blocks are movably connected to two tie rods via a single connecting rod. The movable mounting of two first locking tongue blocks on one side of the base plate and two second locking tongue blocks on the other side allows the first and second locking tongue blocks to automatically engage with each other during direct assembly of two hydraulic supports, thus providing more stable installation conditions for the base plates and bases of adjacent hydraulic supports.

[0004] However, the aforementioned patent requires that the bases be evenly arranged and the locking tongue blocks be on the same horizontal plane before they can be used to connect adjacent bases. In actual use, however, the ground in mines and other similar locations is not perfectly level due to mining requirements. When some bases are tilted, they cannot be adjusted, resulting in unstable or non-connection of adjacent locking tongue blocks. Therefore, this utility model proposes a stable hydraulic support base structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a stable hydraulic support base structure to solve the problem of the base not being able to be leveled as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable hydraulic support base structure, the stable hydraulic support base structure comprising: a base and a support seat, a hydraulic cylinder fixedly connected to the base, a reinforcing plate connected to the output end of the hydraulic cylinder via a sliding plate, the reinforcing plate being slidably connected to the support seat, a wedge fixedly connected to the base, the wedge being slidably connected to the sliding plate, and the support seat being rotatably connected to the wedge.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the hydraulic cylinder can drive the movement of the reinforcing plate, thereby driving the support base to rotate through the support rod, thus adjusting the base to be level.

[0019] 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.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a stable hydraulic support base structure, comprising: a base 3 and a support seat 8. A base plate 2 is fixedly connected to one side of the base 3, which increases the contact area between the base 3 and the ground, thereby enhancing stability. A support seat 1 is fixedly connected to the upper side of one end of the base 3, through which a hydraulic support can be connected and installed. An installation groove 4 is formed on the surface of the base 3, and a hydraulic cylinder 5 is fixedly connected in the installation groove 4, through which the entire structure can be leveled. A wedge block 7 is located at the end of the base 3 away from the support seat 1 and is fixedly connected to it. The wedge 7 is triangular in structure, and the inclined surface of the wedge 7 is detachably mounted with an installation block 6. The installation block 6 is detachably mounted on the end of the base 3 away from the support seat 1, which facilitates the adjustment of the installation block 6. The surface of the installation block 6 is provided with a through groove 9, the surface of the wedge 7 is provided with a through groove 10, and the surface of the support seat 8 is provided with an inclined groove 11. The vertical projection lengths of the three grooves 9, 10 and 11 are equal and the positions are the same, so as to ensure that the reinforcing plate 13 can maintain translation when it moves, while the support seat 8 maintains stable rotation. The inclined groove 11 is parallel to the inclined surface of the installation block 6.

[0021] After the base 3 and the hydraulic support are installed, start the hydraulic cylinder 5. The hydraulic cylinder 5 drives the reinforcing plate 13 to move, thereby driving the support seat 8 to rotate, so as to level the base 3.

[0022] A support rod 15, a sliding plate 16, and a slider 14 are fixedly connected to the surface of the reinforcing plate 13. The support rod 15 is slidably connected to the inclined groove 11, and one end of the support base 8 is rotatably connected to the wedge block 7. When the hydraulic cylinder 5 moves the support rod 15 through the reinforcing plate 13, the support base 8 begins to rotate slowly under the action of the inclined groove 11, thereby lifting the base 3. The sliding plate 16 is slidably connected to the second sliding groove 10, and the slider 14 is slidably connected to the first sliding groove 9. The slider 14 guides the reinforcing plate 13 and supports the support base 8. The output end of the hydraulic cylinder 5 slides through the base 3 and the wedge 7 in sequence and is fixedly connected to the slide plate 16. The hydraulic cylinder 5 can drive the slide plate 16 to move. The inclined surface of the support seat 8 contacts the lower inclined surface of the wedge 7. A buffer pad 12 is fixedly connected to the upper side of one section of the support seat 8. The buffer pad 12 can buffer the contact position between the wedge 7 and the support seat 8 to avoid long-term contact pressure damage. The buffer pad 12 contacts the wedge 7. A pulley 17 is rotatably connected to the end of the support seat 8 away from the base 3. The pulley 17 facilitates the movement of the base 3.

[0023] After the hydraulic cylinder 5 is activated, it can drive the slide plate 16 to slide outward along the slide groove 10. At this time, the reinforcing plate 13 begins to move synchronously. At this time, the support rod 15 slides along the inclined groove 11, thereby forcing the support seat 8 to rotate. The outer arc surface of the support seat 8 slides along the ground, thereby changing the tilt state of the base 3 and making it horizontal.

[0024] When this device is working, the movement of the reinforcing plate 13 can drive the support base 8 to rotate, thereby making the base 3 horizontal. At the same time, when it is necessary to move the base 3, the hydraulic cylinder 5 drives the slide plate 16 to slide to the end of the slide groove 10. At this time, the support base 8 will rotate to the maximum angle, and the pulley 17 will contact the ground. Then, when the base 3 is moved by other equipment, the contact area with the ground can be reduced, which facilitates mechanical traction. The device is easy to use. At the same time, the tilt of the two bases 3 on both sides can be quickly and accurately adjusted by the support base 8 to maintain the overall level.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
