Abstract
The utility model relates to a ground pit type car lifting jack driven support head. A spring composition mechanism is arranged in a back and forth telescopic mechanism of the driven support head and is fixed through a pin shaft, a side plate of the driven support head is in interference fitting with the support head, a technological hole is arranged on the side plate of the driven support head, corresponding to the pin shaft, and an end cover is arranged at the tail of the support head. In the utility model, as the technological hole is arranged on the side plate of the driven support head, corresponding to the pin shaft, when the spring composition mechanism is damaged, the side plate is not needed to be disassembled, a stretch screw of the pin shaft is loosened through the technological hole, the pin shaft quits from the technological hole, and a spring composition is taken out from the tail of the support head composition. The ground pit type car lifting jack driven support head has the advantages of convenient maintenance and part saving.
Description
Technical field
The utility model relates to the parts of a kind of car body unwheeling unit, particularly a kind of passive holder head that is used for ground pit type car lifting J-Horner car body lift unit.
Background technology
For guaranteeing the safe operation of train, the ground pit type car lifting J-Horner is one of essential large-scale key equipment of motor car inspection and repair.Car body lifting holder head is the vitals of car body unwheeling unit, ground pit type car lifting J-Horner in this development, design-calculated holder head is rotary, unwheeling holder head is for being suitable for the width of different automobile types, the design of the holder head of car lifting J-Horner car body lift unit is not only elastic, sway, also will rotate 90 degree, and elastic length reaches nearly 350mm.In every cover car body lift unit, be equipped with one and initiatively hold in the palm head, a passive holder head, not being both in the elastic mechanism of holder head of two holder heads, increased by a sleeve spring in the passive holder head and formed mechanism, design goal is to reduce the rigidity distortion of car body lift unit when the heavy burden unwheeling.In the process of the test, the screw damage occurred holding out against, split out this mechanism, because biside plate all is an interference fit because spring is wherein formed mechanism, during assembling, be to use hand hammer to knock to squeeze into, if remove firmly, can't install once more, cause this part to be scrapped, the waste resource.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, solves maintenance problem, and a kind of band auxiliary hole is provided, and the spring of damage for convenience detach is formed the passive holder head of mechanism.
The technical solution of the utility model is: the passive holder head of a kind of ground pit type car lifting J-Horner, be provided with spring in the elastic mechanism of passive holder head and form mechanism, spring is formed mechanism and is fixed by bearing pin, passive holder cephalic pleurite is an interference fit with the holder head, have auxiliary hole with the cooresponding position of bearing pin on the described passive holder cephalic pleurite, the afterbody of holder head is provided with end cap.
The beneficial effects of the utility model are: the utility model is provided with auxiliary hole at passive holder cephalic pleurite place and the cooresponding position of bearing pin, when spring is formed mechanism's damage, can dismantle side plate, unclamp by the screw that holds out against of auxiliary hole bearing pin, the place withdraws from bearing pin by auxiliary hole, and the afterbody of being made up of the holder head is formed taking-up with spring again.Easy to maintenance, save parts.

The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model:
The passive holder head of a kind of ground pit type car lifting J-Horner, be provided with spring in the elastic mechanism of passive holder head and form mechanism 1, it is fixing by bearing pin 2 that spring is formed mechanism 1, passive holder cephalic pleurite 3 is an interference fit with the holder head, have auxiliary hole 4 with the cooresponding position of bearing pin on the described passive holder cephalic pleurite 3, the afterbody of holder head is provided with end cap.
When spring is formed mechanism's damage, can dismantle holder cephalic pleurite 3, unclamp by the screw that holds out against of auxiliary hole 4 bearing pin 2,4 places withdraw from bearing pin by auxiliary hole, a holder afterbody of forming spring are made of to take out again to get final product.
