Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a high-efficiency hydraulic lifting foundation settlement compensation structure. Background Art

[0002] Cranes, as key equipment, play a vital role in modern construction and heavy lifting operations. However, during crane operation, they often face the problem of foundation settlement, which is mainly caused by factors such as insufficient foundation bearing capacity, soil compression deformation, or changes in groundwater levels. Foundation settlement not only affects the stability and safety of the crane but can also cause lifting operations to be interrupted, increasing construction costs and time.

[0003] The existing crane support cantilever bottom support leg and cantilever are in a fixed connection structure. During the operation of the crane, the movement of the boom causes the force direction of the main body to change, which increases or decreases the force on the support cantilever on one side of the crane, causing the support cantilever to tilt. When tilting, one side of the bottom of the support leg is lifted up, resulting in uneven force on the support leg. Due to ground subsidence, the tilt angle continues to expand. If the lifting work is carried out for a long time without changing the support point, the supporting effect of the crane will be reduced. In severe cases, the connection between the support leg and the cantilever will break, causing the crane to fall.

[0004] Therefore, the present application provides a high-efficiency hydraulic lifting foundation settlement compensation structure to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a high-efficiency hydraulic lifting foundation settlement compensation structure to solve the problem that the existing crane support cantilever bottom support leg and the cantilever are fixedly connected. During the operation of the crane, the movement of the boom causes the force direction of its body to change, so that the force on the support cantilever on one side of the crane increases or decreases, causing the support cantilever to tilt. When tilting, one side of the bottom of the support leg is lifted up, resulting in uneven force on the support leg. Due to ground settlement, the tilt angle continues to expand. If the lifting work is carried out for a long time without changing the support point, the supporting effect of the crane is reduced. In severe cases, it may cause the connection between the support leg and the cantilever to break, causing the crane to tip over.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0026] The following describes in detail a high-efficiency hydraulic lifting foundation settlement compensation structure provided by the present invention, in conjunction with the accompanying drawings and specific embodiments. It is also noted that, to provide a more detailed description, the following embodiments are best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternatives to implement them. Furthermore, the accompanying drawings are only for the purpose of describing the embodiments in more detail and are not intended to limit the present invention to any specific extent.

[0027] like Figure 1 - Figure 5 As shown, an embodiment of the utility model provides a high-efficiency hydraulic lifting foundation settlement compensation structure, including: a support rod 1, the top of which is connected to the crane support cantilever through a hydraulic cylinder, wherein a hydraulic cylinder is fixedly installed on the end of the support cantilever away from the crane, the piston rod on the hydraulic cylinder faces downward, and the end is fixedly connected to the top of the support rod 1, and the bottom end of the support rod 1 is an arc-shaped structure, that is, the two symmetrical edges at the bottom of the support rod 1 are rounded, so that the bottom of the support rod 1 is a semicircular structure.

[0028] The support leg 2 is a truncated cone structure with a connecting seat 3 on the top. A movable groove 5 is provided on the top of the connecting seat 3. The movable groove 5 is a U-shaped groove structure, and one pair of opposite side walls is an open structure from bottom to top. The bottom arc structure of the support rod 1 abuts against the bottom of the movable groove 5. The support rod 1 is configured to rotate inside the movable groove 5 with the bottom contact point of the two as the center of the circle, and the rotation surface is parallel to the telescopic direction of the crane support cantilever.

[0029] There are two tension springs 6, which are symmetrically arranged and connected between the support rod 1 and the support leg 2, and the connection line of the tension spring 6 is parallel to the rotation surface of the support rod 1, wherein the first ear plate 11 and the second ear plate 21 are fixedly connected to the two sides of the support rod 1 and the support leg 2 respectively, and the first ear plate 11 and the second ear plate 21 are used to cooperate with the connection of the tension spring 6.

[0030] The pad 4 is fixed to the bottom of the support leg 2 and is used to increase the friction between the support leg 2 and the ground. The pad 4 and the support leg 2 are detachably connected to facilitate replacement of the pad 4 after wear.

[0031] like Figure 3 and Figure 5 As shown, two slide rods 12 are symmetrically and vertically fixedly connected to the two sides of the support rod 1 adjacent to the first ear plate 11; slide grooves 31 are opened on both sides of the connecting seat 3, and the slide rods 12 are slidably connected with the slide grooves 31.

[0032] By opening sliding grooves 31 on both sides of the movable groove 5 on the connecting seat 3, it is convenient for the slide rod 12 to pass through, and cooperate with the sliding connection. When the hydraulic cylinder on the crane support cantilever retracts, the slide rod 12 abuts against the top of the sliding groove 31 to lift the support leg 2 without affecting the rotation activity inside the movable groove 5 of the support rod 1 when supporting the crane.

[0033] like Figure 1 and Figure 4 As shown, a mounting groove 8 is provided on the support leg 2, and the mounting groove 8 is provided at the inclined surface of the cone of the support leg 2, and there are multiple mounting grooves 8. The multiple mounting grooves 8 are distributed in a circular array on the support leg 2, and the bottom of the mounting groove 8 is parallel to the bottom of the support leg 2. Limiting grooves 81 are provided on both sides of the mounting groove 8, and a positioning groove 82 is provided at one end of the limiting groove 81 close to the center of the support leg 2. A mounting hole 83 connecting the upper and lower surfaces of the support leg 2 is provided at the bottom of the mounting groove 8; a connecting column 41 is vertically provided on the top of the pad 4, wherein a plurality of connecting columns 41 are provided, and the setting position corresponds to the mounting groove 8, the connecting column 41 is socket-connected with the mounting hole 83, and the top of the connecting column 41 passes through the mounting hole 83 into the interior of the mounting groove 8.

[0034] By fixing the backing plate 4 to the bottom of the support leg 2 , the connecting column 41 on the top of the backing plate 4 passes through the mounting hole 83 and protrudes into the interior of the mounting groove 8 .

[0035] like Figure 4 As shown, it also includes a fixing component 7, which includes: a card plate 71, which is slidably connected with the limit groove 81; a card groove 72, which is opened on the card plate 71 and has an open structure at one end; a card block 73, which is arranged on the card plate 71 at both sides of one end of the opening of the card groove 72, and the card block 73 protrudes from the two side walls of the card plate 71, and the card block 73 is engaged with the positioning groove 82; a pull block 74, which is arranged on the end of the card plate 71 away from the card block 73, and protrudes from the top of the card plate 71, so as to facilitate the removal of the fixing component 7 from the inside of the mounting groove 8.

[0036] By providing a card slot 72 on the card plate 71, the plates on both sides of the card slot 72 have a certain elasticity, so that the two card blocks 73 can be driven close to each other by external force, and automatically reset and restore when the external force is lost. By providing a positioning groove 82 at the end of the limit groove 81, the reset mouth of the card block 73 can realize automatic connection between the two, thereby realizing the positioning of the fixed component 7.

[0037] Further, such as Figure 2 As shown, a ring groove 42 is provided on the column of the connecting column 41 located inside the mounting groove 8, and the ring groove 42 is engaged with the clamping groove 72. The width of the clamping groove 72 is larger than the diameter of the column at the position of the ring groove 42 on the connecting column 41, and when the two clamping blocks 73 on the fixing component 7 are retracted inward, the ring groove 42 can also pass through the clamping groove 72.

[0038] The technical solution provided by the present invention is that when the crane unfolds the supporting boom, the hydraulic cylinder at the end of the supporting boom is pressed down, driving the support rod 1 and the support leg 2 to descend and contact the ground, and multiple supporting booms (usually 4 cross supports) cooperate to support the crane body, thereby ensuring the stability of the lifting operation. When the support leg 2 supports, the movement of the boom during the operation of the crane causes the force direction of the body to change, so that the force on the supporting boom on one side of the crane increases or decreases, causing the supporting boom to tilt. During the tilting process, the support rod 1 and the support leg 2 are relatively tilted, and the bottom of the support rod 1 is tilted. The bottom of the support leg 2 is always in contact with the bottom of the movable groove 5 for support, and at the same time ensures that the support leg 2 is always in close contact with the ground, thereby improving the support effect on the crane. Among them, by setting a detachable pad 4 structure, it is convenient to increase the contact friction between the support leg 2 and the ground when supporting the crane. Furthermore, a pointed cone structure can be provided at the bottom of the pad 4, which is convenient for improving the grip of the support leg 2 when supporting on muddy and sandy ground. By setting a tension spring 6, it is ensured that when the support leg 2 is not in contact with the ground, the support rod 1 is always in a vertical state with the support leg 2, which is convenient for the support leg 2 to be parallel to the ground when the cantilever is expanded.

[0039] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. While specific details are described in detail in the preferred embodiments of this invention to provide a thorough understanding, those skilled in the art will be able to fully understand this invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
