Description

Technical Field

[0001] This utility model relates to the field of support technology, and in particular to a support with high support strength. Background Technology

[0002] The essence of a stent is a support structure with a specific structure. Its core function is to resist external forces, maintain shape, and prevent collapse or occlusion in various application scenarios.

[0003] Existing supports are at risk of damage or even failure when suddenly supporting heavy loads or subjected to significant pressure. Moreover, the risk is much greater than when the same weight or pressure is applied slowly and smoothly, and they cannot meet the needs of workers.

[0004] Therefore, we propose a high-strength support bracket to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a support with high strength.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-strength support bracket includes a bracket body. A piston oil tank is slidably connected to the lower end of the bracket body. A piston is slidably connected inside the piston oil tank. An oil push rod is fixedly connected to the piston. The push rod slides through the piston oil tank and is fixedly connected to the bracket body at the end away from the piston oil tank. A fixing block is fixedly connected to the push rod. A pin is fixedly connected to the right end of the fixing block. Four rectangularly distributed support rods are fixedly connected to the lower end of the piston oil tank. A base is fixedly connected to the lower end of the four support rods. A ring is fixedly connected to the bracket body. Three circumferentially distributed oil pipes are rotatably connected to the ring. A support device is provided at the end of each oil pipe away from the bracket body. A lifting device is fixedly connected to the right side of both the bracket body and the piston oil tank.

[0007] Preferably, the lifting device includes a support plate fixedly connected to the support body and the right side of the piston oil tank. A worm gear is rotatably connected to the support plate at the lower end. A worm is meshed with the rear side of the worm gear. A handle is fixedly connected to the right end of the worm. A threaded rod is fixedly connected to the worm gear. The threaded rod is threadedly connected to the two support plates. A lifting plate is threadedly connected to the threaded rod.

[0008] Preferably, a limiting frame is fixedly connected to the lower end of the support plate located at the upper end, and the limiting frame is slidably connected to the lifting plate.

[0009] Preferably, the lifting plate has a sliding groove, a connecting block is slidably connected in the sliding groove, a vertical plate is fixedly connected to the connecting block, and a groove is provided on the connecting block, the groove matching the pin at the right end of the fixed block.

[0010] Preferably, the lower end of the piston oil tank is connected to a three-way pipe, the three-way pipe is equipped with a valve, and each port of the three-way pipe is fixedly connected to an oil delivery pipe. Each oil delivery pipe is fixedly connected to a corresponding oil pipe and passes through the outer wall of the corresponding oil pipe and communicates with it.

[0011] Preferably, the support device includes a support block with symmetrical rectangular grooves on the support block. A conical plate is slidably connected in each of the rectangular grooves. An oil tank is fixedly installed in the support block. Two symmetrical hydraulic rods are slidably connected in the oil tank. The two hydraulic rods pass through the oil tank and are fixedly connected to the corresponding conical plates. The oil tank is connected to an oil pipe.

[0012] Compared with existing technologies, the advantages of this utility model are: 1. When the support suddenly supports a heavy object or is subjected to great pressure, the support will slowly descend and use the push rod and piston to deliver hydraulic oil from the piston oil tank to each oil tank to relieve the pressure impact on the support.

[0013] 2. When the hydraulic rod of the oil tank is pushed to both sides, the cone plate will break through the soil layer, increase the contact area between the support device and the soil layer, and increase the support strength of the support.

[0014] In summary, this invention can alleviate the impact of heavy objects and large pressure on the support and improve the support strength of the support. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-4 A high-strength support bracket includes a bracket body 1. A piston oil tank 4 is slidably connected to the lower end of the bracket body 1. The piston oil tank 4 is filled with hydraulic oil, and the amount of hydraulic oil in the tank is sufficient to allow each oil tank 19 to fully extend the hydraulic rod. A piston is slidably connected inside the piston oil tank 4, and a push rod 2 is fixedly connected to the piston. The push rod 2 slides through the piston oil tank 4 and is fixedly connected to the bracket body 1 at the end away from the piston oil tank 4. A fixing block 3 is fixedly connected to the push rod 2, and a pin is fixedly connected to the right end of the fixing block 3. Four rectangular support rods 5 are fixedly connected to the lower end of the piston oil tank 4, and a base 6 is fixedly connected to the lower end of the four support rods 5. A ring 7 is fixedly connected to the bracket body 1, and three circumferentially distributed oil pipes 8 are rotatably connected to the ring 7. The oil pipes 8 can be retracted for easy transportation. A support device is provided at the end of the oil pipes 8 away from the bracket body 1. A lifting device is fixedly connected to the right side of the bracket body 1 and the piston oil tank 4.

[0019] The lifting device includes a support plate 9 fixedly connected to the right side of the bracket body 1 and the piston oil tank 4. A worm gear 10 is rotatably connected to the lower support plate 9, and a worm 11 is meshed with the rear side of the worm gear 10. A handle is fixedly connected to the right end of the worm 11. A threaded rod 12 is fixedly connected to the worm gear 10, and the threaded rod 12 is threadedly connected to the two support plates 9. A lifting plate 13 is threadedly connected to the threaded rod 12. A limit frame 14 is fixedly connected to the lower end of the upper support plate 9. The limit frame 14 is slidably connected to the lifting plate 13. The lowest height of the limit frame 14 is equal to the lowest height of the fixed block 3. The initial position of the lifting plate 13 is at the bottom end of the limit frame 14. A sliding groove is provided on the lifting plate 13, and a connecting block 15 is slidably connected in the groove. A vertical plate is fixedly connected to the connecting block 15, and a groove is provided on the connecting block 15. The groove matches the pin at the right end of the fixed block 3. When they are at the same height, the vertical plate can be manipulated to move the connecting block 15 to the right, so that the pin is inserted into the groove.

[0020] The lower end of the piston oil tank 4 is connected to a three-way pipe 16, and a valve 17 is provided on the three-way pipe 16. Each port of the three-way pipe 16 is fixedly connected to an oil supply pipe 18. Each oil supply pipe 18 is fixedly connected to the corresponding oil pipe 8 and passes through the outer wall of the corresponding oil pipe 8 to communicate with it. During transportation and when not in operation, the valve 17 is in the closed state. The valve 17 is opened when support work is required.

[0021] The support device includes a support block 20, on which there are left and right symmetrical rectangular grooves. A cone plate 21 is slidably connected in each rectangular groove. The outer side of the cone plate 21 is conical and can break through hard soil layers. An oil tank 19 is fixedly installed in the support block 20. Two left and right symmetrical hydraulic rods are slidably connected in the oil tank 19. The two hydraulic rods pass through the oil tank 19 and are fixedly connected to the corresponding cone plate 21. The oil tank 19 is connected to the oil pipe 8.

[0022] When using this utility model, first dig a hole of appropriate depth in the ground and bury the support block 20 inside the hole. Fix the base 6 on the ground, and then open the valve 17. When the support supports the heavy object, the support body 1 drives the push rod 2 to descend. The hydraulic oil in the piston oil tank 4 is squeezed by the push rod 2 and the piston and then transported to each oil tank 19 through the oil pipe 8. This causes the hydraulic rod to push the cone plate 21 into the soil layer on both sides of the support block 20, increasing the contact area between the support device and the soil layer, relieving the pressure impact on the support and increasing the support strength of the support. After the support work is completed, the connecting block 15 is moved to the right by manipulating the vertical plate, so that the pin is inserted into the groove of the connecting block 15. Then, the handle is operated to rotate the worm gear 11, which drives the worm wheel 10 and the threaded rod 12 to rotate, so that the lifting plate 13 drives the push rod 2 and the piston to rise to the initial position. Under the action of pressure, the hydraulic oil flows back into the piston oil tank 4. Then, the valve 17 is closed and the oil pipe 8 is retracted. It should be noted that this utility model is applicable to support work in shallow outdoor soil layers (without hard rocks).

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
