Summary of the invention
In order to solve shortcomings and deficiencies of the prior art, the utility model provides a kind of mining support trolley, and the support is small
Vehicle can supporting mine car, impaired mine car is transported into helpdesk in time and is repaired, it is easy to operate, it is highly-safe, production is simple,
It is convenient for carrying, transport failure can be handled in time, influence the rail transport time after reducing mine car failure.
It is to solve technical solution used by its technical problem: a kind of mining support trolley, including pedestal, lifting group
Part and supporting table, the pedestal lower part are provided with wheel, and the lifting assembly is installed between pedestal and supporting table, the lifting
Component includes upper connecting rod, lower link, pin shaft, lead screw, ratchet and pawl, and described upper connecting rod one end and lower link one end pass through pin shaft
Hingedly, the upper connecting rod other end and supporting table are hinged, and the lower link other end and pedestal are hinged, and the ratchet is mounted on the base, institute
It states pawl to be articulated on lower link and be adapted with ratchet, the ratchet and pawl is for preventing lower link from reversing, the lifting
Component is symmetrically arranged with two groups, and two groups of pin shafts are connected by horizontally disposed lead screw, the lead screw through two groups of pin shafts, and
It is threadedly coupled with two groups of pin shafts, the thread rotary orientation of the lead screw is arranged at axial symmetry from the middle to both ends, the lead screw rotation
Supporting table can be driven to move up and down, the supporting table is provided with the perforation for connecting mine car.
When the failures such as bearing damage, off-axis, wheel breakage occurs in the process of running in mine car, when cannot run, will support
It after the lifting assembly of trolley is shunk, is placed under the meeting and discussing of mine car damage side, the mine car that the perforation by supporting trolley will be damaged
It is connected together with trolley is supported, then rotational lead screw, drives two groups of pin shafts mobile to lead screw center, the mobile band of two groups of pin shafts
Upper and lower connecting rod swing is moved, lifting assembly is upheld, supporting table is driven to move up, while the swing band pawl of lower link exists
It is slipped on ratchet, supporting table gradually jacks up mine car, so that the wheel of mine car damage side is de-orbited, the gravity of mine car is in support
Trolley shrinks the lifting assembly for supporting trolley, and upper and lower connecting rod direction opposite when upholding respectively to lifting assembly is swung, this
When lower link on pawl insertion ratchet hook tooth, prevent lower link swing, prevent supporting table from declining, support trolley will damage
Mine car check helpdesk and repair.
The beneficial effects of the utility model are: support trolley provided by the utility model, it can not only be by failure
Mine car is transported to helpdesk in time and repairs, and influences the rail transport time after reducing mine car failure, and easy to repair, mentions
High maintenance efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the working state schematic representation of the utility model.
1 is pedestal in figure, and 2 be lifting assembly, and 3 be supporting table, and 4 be mine car, and 11 be wheel, and 21 be upper connecting rod, under 22 are

Specific embodiment
Implementation case given below is quasi-, and the utility model is described in further detail, but is not to be construed as practical new to this
The limitation of type protection scope, those skilled in the art's some nonessential modifications and adaptations according to the present utility model still belong to this
The protection scope of utility model.
As shown, a kind of mining support trolley, including pedestal 1, lifting assembly 2 and supporting table 3, the setting of 1 lower part of pedestal
There is wheel 11, lifting assembly 2 is installed between pedestal 1 and supporting table 3, and lifting assembly 2 includes upper connecting rod 21, lower link 22, pin
Axis 23, lead screw 24, ratchet 25 and pawl 26,21 one end of upper connecting rod and 22 one end of lower link are hinged by pin shaft 23, upper connecting rod 21
The other end and supporting table 3 are hinged, and 22 other end of lower link and pedestal 1 are hinged, and ratchet 25 is mounted on pedestal 1, and pawl 26 joins
It is adapted on lower link 22 and with ratchet 25, for preventing lower link 22 from reversing, lifting assembly 2 is symmetrical for ratchet 25 and pawl 26
It is provided with two groups, two groups of pin shafts 23 are connected by horizontally disposed lead screw 24, and lead screw 24 is through two groups of pin shafts 23, and lead screw
24 are threadedly coupled with two groups of pin shafts 24, and the thread rotary orientation of lead screw 24 is arranged at axial symmetry from the middle to both ends, and lead screw 24 rotates
Supporting table 3 can be driven to move up and down, supporting table 3 is provided with the perforation 31 for connecting mine car.
When the failures such as bearing damage, off-axis, wheel breakage occurs in the process of running in mine car 4, when cannot run, will support
After the lifting assembly 2 of trolley is shunk, it is put into mine car 4 and damages under the meeting and discussing of side, the mine that the perforation 31 by supporting trolley will be damaged
Vehicle 4 is connected together with trolley is supported, then rotational lead screw 24, drives two groups of pin shafts 23 mobile to 24 center of lead screw, two groups of pins
