Description

Technical Field

[0001] This utility model relates to the field of hydraulic supports, specifically, to a hydraulic support base and hydraulic support that are easy to transport down into the well. Background Technology

[0002] Currently, the transportation of hydraulic supports to the mine shaft primarily utilizes small cage hoisting. However, the limited loading space within these small cages restricts the transport length, necessitating the disassembly and disassembly of the hydraulic supports before transport. Even after disassembly, the length of the largest non-removable component—the base—still falls short of the cage's transport requirements. Furthermore, the middle section of the base houses a relatively long push rod, requiring a coordinated mechanism between the rear overpass plate and the push rod to guide its movement. Simply shortening the base length does not adequately meet the guide rod's guidance requirements.

[0003] Utility model patent CN220469979U discloses a hydraulic support base and a hydraulic support. The hydraulic support base includes two main rib assemblies, each comprising connected inner and outer main ribs, with the two inner main ribs positioned between the two outer main ribs; at least one first box structure positioned between the two inner main ribs and connected to them; and at least one connecting plate assembly positioned between the two outer main ribs and connected to them. This hydraulic support base and hydraulic support occupy less space, have good mechanical properties, and high connection strength, which helps reduce the number of parts and improves assembly efficiency. However, the disclosed structure is not easy to disassemble and cannot meet the requirements for cage-downloading transportation and guiding the push rod. Utility Model Content

[0004] In order to meet the requirements of using a small cage to transport the hydraulic support down the well and to ensure that the push rod can be fully guided during movement, the technical solution adopted by this utility model is: a hydraulic support base that is easy to transport down the well, including a pair of outer main rib assemblies, a pair of inner main rib plates, a rear bridge plate and a push rod; The rear bridge plate is connected between a pair of main stiffening plates inside the base. The rear bridge plate and the pair of main stiffening plates inside the base together form a push rod assembly cavity. The push rod is detachably disposed in the push rod assembly cavity. The inner main rib plate of the base is disposed between a pair of outer main rib assemblies of the base, and the rear ends of the pair of inner main rib plates of the base and the rear end of the rear bridge plate are respectively flush with the rear end of the outer main rib assembly of the base. The push rod is provided with second guide strips on both sides of the main stiffening plate inside the base, and a pair of first guide strips are provided on the inner side of the main stiffening plate inside the base to cooperate with the second guide strips, so that when the push rod is pushed, the first guide strips and the second guide strips limit and guide the push rod in the vertical direction.

[0005] Beneficial effects: By coordinating the inner main rib plate, the rear crossbar plate, and the outer main rib assembly, the rear ends of these three components are aligned, thus preventing the overall length of the hydraulic support base from becoming excessively long due to the inner main rib plate or the rear crossbar plate exceeding the outer main rib assembly, which would prevent the hydraulic support from being transported down the well using a small cage. Simultaneously, it also enables the vertical guidance of the push rod.

[0006] Based on the above, the push rod assembly cavity is clearance-fitted with the push rod so that when the push rod is pushed, the push rod assembly cavity can limit and guide the push rod in the left and right directions.

[0007] Beneficial effects: Through the cooperation between the push rod and the push rod assembly cavity, the push rod can be accommodated in the push rod assembly cavity and also has a certain amount of room for movement, which can guide and limit the push rod in the left and right directions.

[0008] Based on the above, the length of the push rod is greater than the length of the outer main rib assembly of the base, so that the rear end of the push rod extends out of the rear overpass plate in the assembled state.

[0009] Beneficial effects: By cooperating with the push rod and the outer main rib assembly of the base, and limiting the push rod's length relative to the outer main rib assembly of the base, it is possible to ensure that the front and rear ends of the push rod can be externally connected to other equipment, facilitating the movement of the hydraulic support base after assembly.

[0010] Based on the above, the push rod is provided with two pairs of second guide bars, and the two pairs of second guide bars are arranged sequentially along the length direction of the push rod.

[0011] Based on the above, the first guide bar and the second guide bar are arranged parallel to each other.

[0012] Beneficial effects: By cooperating with the push rod, the first guide bar, and the second guide bar, the second guide bar on the push rod can slide with the first guide bar, effectively ensuring the smoothness of the guiding process.

[0013] Based on the above, the rear end of the rear bridge plate is detachably connected to an anti-slip lug for an external anti-slip system, and the anti-slip lug is located directly above the push rod.

[0014] Beneficial effects: By detachably installing anti-slip ear plates on the top of the push rod, the anti-slip ear plates can be removed from the rear bridge plate during underground transportation, thereby shortening the size of the rear bridge plate and facilitating underground transportation. At the same time, the anti-slip ear plates can also be used to protect the push rod during movement.

[0015] Based on the above, the rear end of the rear bridge plate and the front end of the anti-slip ear plate are respectively provided with a pair of corresponding pin holes, and the rear bridge plate and the anti-slip ear plate are detachably connected by a pair of pins.

[0016] Beneficial effects: By using a pin to detachably connect the rear bridge plate and the anti-slip ear plate, the anti-slip ear plate can be disassembled and reused during underground transportation, ensuring that the function of the external anti-slip system can be retained while shortening the length of the rear bridge plate.

[0017] This embodiment also provides a hydraulic support, which is equipped with the aforementioned hydraulic support base that facilitates transportation downhole.

[0018] This utility model has substantial features and advancements compared to existing technologies. Specifically, it provides a hydraulic support base that facilitates underground transportation. On one hand, by shortening the length of the inner main rib plate, the inner main rib plate is made flush with the outer main rib assembly. On the other hand, by shortening the length of the rear cross plate, the disassembled rear cross plate is made flush with the outer main rib assembly. This avoids the situation where the overall length of the hydraulic support base is too long due to the inner or rear cross plate exceeding the outer main rib assembly, making it unsuitable for underground transportation using a small cage. Simultaneously, by setting two pairs of second guide strips on both sides of the push rod and a pair of first guide strips on both sides of the inner main rib plate, the vertical guidance of the push rod can be achieved through the cooperation between the first and second guide strips.

[0019] Furthermore, by designing the width of the push rod to match the width of the push rod assembly cavity, the push rod can be guided and limited in the left and right directions.

[0020] Furthermore, by detachably connecting the anti-slip ear plate to the rear side of the rear overpass plate via a pin, the function of connecting the anti-slip system via the anti-slip ear plate is retained even while shortening the rear overpass plate. Attached Figure Description
