Abstract
The utility model discloses a tamping pickaxe protection cover with a leaf spring shock absorption system, and belongs to the field of shock absorption devices. The tamping pickaxe protection cover is mainly used for small machines like tamping pickaxes and comprises a protection cover assembly. The protection cover assembly is provided with an upper spring tensioning frame and a lower spring tensioning frame. The upper spring tensioning frame is provided with an upper rotating shaft installation hole, an upper spring hanging device and a protection cover upper portion locating pin hole. The lower spring tensioning frame is provided with a lower rotating shaft installation hole, a lower spring hanging device and a protection cover lower portion locating pin hole. According to the technical scheme, the upper spring tensioning frame and the lower spring tensioning frame can deform when a pressing protection cover handle descends vertically, so that the distance between springs on the two spring tensioning frames is increased, the springs are tensioned, and vibration of a machine is buffered in the use process.
Description
Technical field
The utility model belongs to damping device field, specifically, relates in particular to a kind of tamping pickaxe protective housing with leaf spring shock mitigation system.
Background technique
In the small engineering machinery of tamping pickaxe class, need to carry out damping to work system, operation system, conventional damping device is rubber column, spring stool, but this damping device shape is single, be subject to connection profile, the spacial influence of operation system, work system larger, and rely on merely rubber column, latch plate to connect quite difficulty, join strength is inadequate, easily there is phenomenon of rupture in its joint, makes the small engineering machinery of tamping pickaxe class in use have potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of tamping pickaxe protective housing with leaf spring shock mitigation system, and it can provide good damping effect, and join strength is large, and assembling is simple.
The tamping pickaxe protective housing with leaf spring shock mitigation system described in the utility model, comprise protective housing combination, described protective housing combination is provided with upper spring draw frame, lower spring draw frame, and described upper spring draw frame is provided with running shaft mounting hole, upper extension spring arrangement, protective housing top positioning pin hole; Described lower spring draw frame is provided with Shaft mounting hole, lower extension spring arrangement, protective housing bottom positioning pin hole.
Say further, between the upper extension spring arrangement of upper running shaft mounting hole site described in the utility model on upper spring draw frame, protective housing top positioning pin hole; Between the Shaft mounting hole and protective housing bottom positioning pin hole of described lower extension spring arrangement on lower spring draw frame.
Compared with prior art, the utlity model has following beneficial effect:
The utility model join strength is high, protective housing handle is vertical produces deformation when descending pressing in assembling and using process, to utilize upper spring draw frame and lower spring draw frame, and then two distances between the spring on spring draw frame are increased, produce and stretch, thereby the vibration in use facility being produced cushions.
