Description
Technical field
The utility model belongs to hoisting crane technical field, is specifically related to the shock absorption device of a kind of hoisting crane OPS.
Background technology
Conventionally hoisting crane OPS is all that the mode that adopts high strength bolt to connect hangs and is arranged on crane bridge one side position on the lower, because this connection mode is to belong to gun iron link, in hoisting crane operational process, can produce vibration, drive OPS to vibrate together simultaneously, when particularly starting, stopping, hoisting, unload at hoisting crane, exist and impact, make vibrations more obvious, for for a long time, at the operating personal of OPS's work, have sense of discomfort.
Utility model content
The purpose of this utility model is the problem for above-mentioned existence, and the shock absorption device of a kind of hoisting crane OPS is provided, and reduces the vibrations of hoisting crane OPS.
To achieve these goals, the technical solution adopted in the utility model is:
A shock absorption device for hoisting crane OPS, is arranged at the junction of OPS and OPS's connection bracket, comprises pull bar, bearing, bump rubber and backing plate, and OPS top is fixedly installed hanger; Pull bar passes hanger, OPS's connection bracket, bearing, bump rubber and backing plate successively, and fixes by packing ring and nut at two ends.
Preferably, bearing top arranges a protective case, and protective case end is fixedly connected with bearing, and protective case surrounds bump rubber, backing plate.
Preferably, described bump rubber is the hollow circular cylinder that adopts elastomeric material to make.
Preferably, described bump rubber consists of recoil spring, sleeve pipe and spring compressor, and recoil spring is sleeved on the pull bar between bearing and backing plate, and at the bottom of recoil spring cover tubing, recoil spring top pocketed springs cap.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
The shock absorption device of a kind of hoisting crane of the present utility model OPS, absorbs by bump rubber is set the vibrations that hoisting crane produces, and improves greatly the vibration problems of OPS, reduces the sense of discomfort of operating personal in OPS; In shock absorption device outside, be provided with protective case simultaneously, can better protect shock absorption device.

The specific embodiment
Embodiment 1:
With reference to Fig. 1-3, the shock absorption device of a kind of hoisting crane OPS, is arranged at the junction of OPS 2 and OPS's connection bracket 1, comprises pull bar 5, bearing 6, bump rubber 4 and backing plate 7, and OPS 2 tops are fixedly installed hanger 8.Pull bar 5 passes hanger 8, OPS's connection bracket 1, bearing 6, bump rubber 4 and backing plate 7 successively, and fixes by packing ring and nut at two ends.The vibrations that produced when starting, stopping, hoisting, unload by hoisting crane 9, absorb by having elastomeric bump rubber 4, reduce the vibrations of OPS 2.Bearing 6 tops arrange a protective case 3, and protective case 3 ends are fixedly connected with bearing 6, and protective case 3 surrounds bump rubber 4, backing plate 7, by protective case 3, can better protect shock absorption device.
In order to make bump rubber 4 reach better shock-absorbing effect, the bump rubber 4 of the present embodiment is the hollow circular cylinder that adopts elastomeric material to make.
Embodiment 2:
With reference to Fig. 4, the present embodiment provides the technical scheme of another kind of shock absorption device, the difference part of this embodiment and embodiment 1 is, described bump rubber 4 ＇ consist of recoil spring 41 ＇, sleeve pipe 42 ＇ and spring compressor 43 ＇, recoil spring 41 ＇ are sleeved on the pull bar 5 between bearing 6 and backing plate 7, and at the bottom of recoil spring 41 ＇ cover tubing 42 ＇, recoil spring 41 ＇ top pocketed springs cap 43 ＇.Recoil spring 41 ＇ bottoms are protected by sleeve pipe 42 ＇, avoid recoil spring 41 ＇ when compressed, and bottom produces torsional deflection; Recoil spring 41 ＇ tops are protected by spring compressor 43 ＇, avoid recoil spring 41 ＇ when compressed, and top produces torsional deflection.
