Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and particularly relates to an anti-falling buffer assembly for a crane. Background Art

[0002] A crane is a heavy machinery with large inertia during operation and is prone to unexpected movements. Once the mechanical limiter of the crane fails, under the action of inertia, the electric hoist or the electric trolley of the crane will collide with the blocking body at the running end. Therefore, a buffer is required. To a certain extent, the buffer can buffer and reduce the occurrence of accidents, improving the safety of crane operation. The buffer of the prior art is generally a polyurethane buffer, which has a short buffering time and is prone to cracking or powdering, thus affecting the buffering effect, and its applicability and practicability are limited. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an anti-falling buffer assembly for a crane with reasonable structural settings and beneficial to improving the use reliability.

[0004] The technical solution for realizing the purpose of the utility model is an anti-falling buffer assembly for a crane, including a mounting seat, and a buffer structure fixed on the mounting seat. The buffer structure includes a buffer seat, a support cylinder, a disc spring body, a control cable, and a buffer pressing block.

[0005] The buffer seat is fixed on the mounting seat through a screw, and the end of the support cylinder is fixed on the side of the buffer seat.

[0006] A cavity is arranged in the buffer seat, and a pillar is fixed at the center of the cavity.

[0007] The disc spring body is sleeved on the pillar, and the center of the disc spring body is clamped and fixed on the pillar.

[0008] The buffer pressing block is arranged at the end of the support cylinder, and the outer end of the buffer pressing block extends out of the end face of the support cylinder.

[0009] Both ends of the control cable are respectively fixed on the outer end of the disc spring body and the end of the buffer pressing block.

[0010] The buffer pressing block contracts in the support cylinder and drives the disc spring body to gradually tighten through the control cable to achieve buffering.

[0011] Further preferably: A plurality of guiding rings are arranged on the outer wall of the support cylinder, and the middle part of the control cable is threaded through the guiding rings.

[0012] Further preferably: A buffer spring is fixed on the side of the buffer seat, and the buffer spring is located in the support cylinder.

[0013] When the buffer pressing block contracts to the end of the support cylinder, it abuts against the buffer spring.

[0016] Further preferably, the support cylinder is a metal cylinder, and the outer diameter of the buffer pressing block matches the inner diameter of the support cylinder.

[0017] The utility model has positive effects: The structure of the utility model is reasonably arranged. Through the disc spring body cooperating with the buffer pressing block through the control cable, the buffer is realized by the contraction of the buffer pressing block in the support cylinder driving the disc spring body to contract, and the contraction and reset of the control cable are also facilitated by the disc spring body.

[0024] Embodiment

[0025] See Figures 1 to 3As shown in the figure, a crane anti-falling buffer assembly includes a mounting seat 1 and a buffer structure 2 fixed to the mounting seat. In this embodiment, the mounting seat is fixed to the buffer position by bolts. When the electric hoist of the crane runs to the end point, it will abut against the buffer structure for buffering.

[0026] In actual application, the buffer structure includes a buffer seat 21, a support cylinder 22, a disc spring body 23, a control cable 24, and a buffer pressing block 25; the control cable is a metal cable body. The support cylinder is a metal cylinder, and the outer diameter of the buffer pressing block matches the inner diameter of the support cylinder. During installation, the buffer seat is fixed to the mounting seat by screws, and the end of the support cylinder is fixed to the side of the buffer seat; a cavity 3 is provided in the buffer seat, and a support column 4 is fixed at the center of the cavity; the disc spring body is sleeved on the support column, and the center of the disc spring body is clamped and fixed on the support column; in this embodiment, the center of the disc spring body can be fixed to the support column by screws or other methods such as buckles or welding to ensure the smoothness and reliability of the use of the disc spring body, and the size of the cavity can be processed and set according to the diameter of the disc spring body to meet the use requirements in different situations. The buffer pressing block is arranged at the end of the support cylinder, and the outer end of the buffer pressing block extends out of the end face of the support cylinder; both ends of the control cable are respectively fixed to the outer end of the disc spring body and the end of the buffer pressing block; the buffer pressing block contracts in the support cylinder and drives the disc spring body to gradually tighten through the control cable to achieve buffering. In this embodiment, the elastic force of the disc spring body can be set as required. This is a conventional structure of the prior art, so it is not described in detail.

[0027] In actual application, a plurality of guiding rings 5 are arranged on the outer wall of the support cylinder, and the middle part of the control cable passes through the guiding rings. The guiding rings can limit the control cable to prevent it from shifting or tilting, and ensure the effectiveness and smoothness of the tension.

[0028] In actual application, a buffer spring 6 is fixed to the side of the buffer seat, and the buffer spring is located inside the support cylinder; the buffer pressing block abuts against the buffer spring when it contracts to the end of the support cylinder. It can cooperate with the disc spring body to achieve double buffering and ensure the effectiveness, smoothness, reliability of buffering.

[0029] In actual application, a plurality of exhaust holes 7 are arranged on the support cylinder. The exhaust holes are mainly used to discharge the gas in the support cylinder, which can ensure that the buffer pressing block can smoothly expand and contract in the support cylinder.

[0030] The utility model has positive effects: The structure of the utility model is reasonably arranged. Through the disc spring body, the control cable is cooperated with the buffer pressing block, and the buffer is realized by the contraction of the buffer pressing block in the support cylinder body driving the disc spring body to contract.
