Abstract
Description
Technical Field
[0001] The utility model relates to an elevator buffer, in particular to an improvement of a hydraulic seat shell. Background Art
[0002] When an elevator extreme fall accident occurs, the elevator's last safety device, the elevator buffer, is activated. Once the elevator buffer is activated, it means that the accident level of the elevator has reached the worst case scenario, and many structures of the elevator itself have failed or been damaged.
[0003] In this case, the outer side of the hydraulic cylinder of the elevator buffer is very easy to be scratched by external debris, so that the hydraulic cylinder body is damaged, affecting the buffering performance of the elevator buffer itself. Utility Model Content
[0004] In order to overcome the disadvantage that the hydraulic cylinder of the existing elevator buffer is easily invalidated by external debris, the utility model provides an elevator buffer with a hemp rope wrapped around the outer shell.
[0005] The utility model solves the technical problem by a technical solution: an elevator buffer, comprising a hydraulic cylinder and a hollow rod at the upper end of the hydraulic cylinder, an upper top plate being provided at the upper end of the hollow rod, a middle top plate being provided on the hydraulic cylinder, a supporting spring being provided between the upper top plate and the middle top plate, a bottom plate being provided at the lower end of the hydraulic cylinder, a braided rope layer being wound around the lower side of the middle top plate of the hydraulic cylinder; an upper fixing device for fixing a braided rope head is provided on the middle top plate, and a lower fixing device for fixing another braided rope head is provided on the bottom plate.
[0006] The material of the braided rope layer is optimized, and the braided rope layer is formed by winding hemp rope.
[0007] The upper and lower fixing devices are further defined in terms of their form. The upper fixing device is provided in an upper fixing hole on the middle top plate, and an upper fixing nail is provided in the upper fixing hole; the lower fixing device is provided in a lower fixing hole on the bottom plate, and a lower fixing nail is provided in the lower fixing hole; the braided rope head is fixed by the upper fixing nail and the lower fixing nail.
[0008] The upper fixing hole is further defined as being arranged transversely on the middle top plate.
[0009] The lower fixing hole is preferably arranged on the upper end surface of the bottom plate.
[0010] In order to increase the protection effect, the braided rope layer is provided with two layers, namely an inner braided rope layer and an outer braided rope layer.
[0011] To facilitate winding and improve the protective effect, the gap between each layer of the inner braided rope layer is larger than that of the outer braided layer.
[0012] In order to facilitate winding, the rope diameters of the inner braided rope layer and the outer braided rope layer are consistent.
[0013] A preferred braided rope diameter is that the rope diameters of the inner braided rope layer and the outer braided rope layer are between 2 mm and 6 mm.
[0014] Preferably, the rope diameters of the inner braided rope layer and the outer braided rope layer are 3 mm.
[0015] The utility model is different from the elevator buffer of the prior art in that the braided rope layer can absorb the impact of hard objects and can absorb the spilled oil when in use.
[0016] The beneficial effects of the utility model are as follows: 1. The braided rope layer has good toughness and can resist the hydraulic cylinder body from being hit by hard objects during transportation and sudden drop, thereby improving the stability of the buffer. 2. The braided rope layer has strong tensile strength and can provide a certain degree of anti-deformation force when the hydraulic cylinder body is deformed, thereby increasing the structural strength of the elevator buffer. 3. The braided rope also has strong oil absorption. When hydraulic oil leaks, the braided rope layer can absorb a small amount of hydraulic oil to prevent the hydraulic oil from scattering all over the floor. BRIEF DESCRIPTION OF THE DRAWINGS
