Description

Technical Field

[0001] This utility model relates to the field of equipment hoisting technology, and in particular to a shock-absorbing and buffering structure for equipment hoisting. Background Technology

[0002] In the field of equipment hoisting technology, traditional hoisting structures mostly rely on a single wire rope or chain to directly connect the hoisting equipment and the object being hoisted, resulting in insufficient shock absorption and cushioning capabilities. When lifting, moving, or lowering operations are performed, the object being hoisted is prone to severe shaking and impact loads due to factors such as sudden changes in gravity and vibrations from the hoisting equipment.

[0003] In existing technologies, when the center of gravity of the suspended object shifts or lateral forces occur during the hoisting process, uneven stress on the hoisting structure is likely to occur. This not only exacerbates local wear on the wire rope or chain, shortens its service life, but may also lead to the risk of breakage due to instantaneous stress concentration.

[0004] Therefore, it is necessary to provide a new shock-absorbing and buffering structure for equipment hoisting to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a shock-absorbing and buffering structure for equipment hoisting.

[0006] The shock-absorbing and buffering structure for equipment hoisting provided by this utility model includes a top plate and a central plate. Multiple annularly distributed sliding rods are fixedly installed at the bottom of the top plate, and two sliding rods form a group. Each group of sliding rods is equipped with a sliding seat that is slidably connected. A hydraulic shock absorber is fixedly installed on the upper surface of the sliding seat, and the other end of the hydraulic shock absorber is fixedly connected to the lower surface of the top plate. A spring A is sleeved on the hydraulic shock absorber.

[0007] The connecting plate is located below the top plate, and corresponding docking components are installed on the connecting plate and the sliding seat. A docking plate is sleeved between the two sets of corresponding docking components.

[0008] The bottom of the connecting plate is fixedly installed with multiple ring-shaped steel wire ropes.

[0009] Preferably, the docking assembly includes a mounting base, on which a rotating shaft is inserted for rotatable connection, and U-shaped frames are fixedly installed on both sides of the rotating shaft, with a connecting rod fixedly installed on the U-shaped frame.

[0010] Preferably, the mounting base in the docking assembly is fixedly mounted on the sliding base or the connecting plate.

[0011] Preferably, one end of the docking plate is rotatably connected to the sleeve rod in the docking assembly on the sliding seat, and the other end of the docking plate is rotatably connected to the sleeve rod in the docking assembly on the connecting plate.

[0012] Preferably, one end of the spring A is fixedly connected to the lower surface of the top plate, and the other end of the spring A is fixedly connected to the upper surface of the sliding seat.

[0013] Preferably, each of the sliding rods is fitted with a spring B, one end of which is fixedly connected to the lower surface of the sliding seat, and the other end of which is fixedly connected to the rod cap at the bottom of the sliding rod.

[0014] Preferably, a lifting ring is fixedly installed on the top of the top plate.

[0015] Compared with related technologies, the shock-absorbing and buffering structure for equipment hoisting provided by this utility model has the following advantages:

[0016] Beneficial effects:

[0017] In this invention, the hydraulic shock absorber can dissipate vibration energy through liquid damping, effectively suppressing high-frequency vibration. Spring A provides elastic buffer when the sliding seat moves upward, and spring B provides reverse support when the sliding seat moves downward, which greatly reduces the impact load during hoisting and the risk of the wire rope breaking due to excessive instantaneous tension. The docking assembly and docking plate form a flexible connection structure. The two work together to enable the central connecting plate to adaptively adjust laterally according to the center of gravity shift or lateral force of the hoisted object, ensuring that the wire ropes are evenly stressed and reducing local wear.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 4 This utility model provides a shock-absorbing and buffering structure for equipment hoisting, which includes a top plate 1 and a central connecting plate 5.

[0026] In the embodiments of this utility model, please refer to Figures 1 to 4 A lifting ring 11 is fixedly installed on the top of the top plate 1, and multiple ring-shaped sliding rods 2 are fixedly installed on the bottom of the top plate 1. Two sliding rods 2 form a group, and a sliding seat 3 is mounted on each group of sliding rods 2. A hydraulic shock absorber 4 is fixedly installed on the upper surface of the sliding seat 3, and the other end of the hydraulic shock absorber 4 is fixedly connected to the lower surface of the top plate 1. A spring A41 is sleeved on the hydraulic shock absorber 4, and one end of the spring A41 is fixedly connected to the lower surface of the top plate 1, and the other end of the spring A41 is fixedly connected to the upper surface of the sliding seat 3.

[0027] The connecting plate 5 is located below the top plate 1, and multiple ring-shaped steel wire ropes 8 are fixedly installed at the bottom of the connecting plate 5. Each steel wire rope 8 has a hook at its end (not shown in the figure). Corresponding docking components 6 are installed on the connecting plate 5 and the sliding seat 3. A docking plate 7 is sleeved between the two sets of corresponding docking components 6. Specifically, the docking component 6 includes a mounting base 61, on which a rotating shaft 62 is inserted. U-shaped frames 63 are fixedly installed on both sides of the rotating shaft 62. A connecting rod 64 is fixedly installed on the U-shaped frame 63. The mounting base 61 in the docking component 6 is fixedly installed on the sliding seat 3 or the connecting plate 5. One end of the docking plate 7 is rotatably connected to the connecting rod 64 in the docking component 6 on the sliding seat 3, and the other end of the docking plate 7 is rotatably connected to the connecting rod 64 in the docking component 6 on the connecting plate 5.

[0028] It should be noted that: the lifting rope of the hoisting equipment is tied to the lifting ring 11, and then the hook on the wire rope 8 is used to hook the corner of the object to be lifted to achieve the hoisting. During the hoisting, under the action of the object's weight, the sliding seat 3 slides down along the sliding rod 2 while stretching the spring A41. The spring A41, together with the hydraulic shock absorber 4, can achieve the buffering effect of the lifting rope, avoiding the hidden danger of the lifting rope of the hoisting equipment breaking due to excessive instantaneous tension.

[0029] It should also be noted that: since the U-shaped frame 63 in the docking assembly 6 is rotatably mounted on the mounting base 61 via the rotating shaft 62, the U-shaped frame 63 can be adjusted in pitch angle on the mounting base 61. At the same time, the docking plate 7 is sleeved on the connecting rod 64 and rotatably connected to the connecting rod 64, so the docking plate 7 can swing left and right. Therefore, the docking assembly 6, in conjunction with the docking plate 7, enables the connecting plate 5 to perform adaptive lateral adjustment.

[0030] Furthermore, each sliding rod 2 is fitted with a spring B9, one end of which is fixedly connected to the lower surface of the sliding seat 3, and the other end of which is fixedly connected to the rod cap at the bottom of the sliding rod 2, further improving the buffering effect on the sliding seat 3.

[0031] In this embodiment: the hydraulic shock absorber 4 can consume vibration energy through liquid damping and effectively suppress high-frequency vibration. The spring A41 provides elastic buffer when the sliding seat 3 moves upward, and the spring B9 provides reverse support when the sliding seat 3 moves downward. The three work together to achieve bidirectional multi-stage buffering of "compression-tension", which greatly reduces the impact load during hoisting and reduces the risk of the wire rope 8 breaking due to excessive instantaneous tension. The docking assembly 6 and the docking plate 7 form a flexible connection structure. The two work together to enable the central connecting plate 5 to adaptively adjust laterally according to the center of gravity shift or lateral force of the hoisted object, ensuring that each wire rope 8 is subjected to uniform force and reducing local wear.

[0032] Both springs A41 and B9 are made of high-strength alloy spring materials (such as 60Si2Mn) and their fatigue resistance is improved through heat treatment. At the same time, anti-corrosion coating is applied to the surface of springs A41 and B9 to extend their service life. Furthermore, the elastic coefficients of springs A41 and B9 are preset according to the lifting weight range to avoid overloading.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
