Description
Technical field
The utility model is related to support device fields, particularly relate to a kind of central axle support device.
Background technology
Support device is suitable for carrying and lifting after semitrailer and special trailer are seted out, it can also be used to various vehicles and set
Support is lifted as very heavy during standby fixed work, is had wide range of applications.
The structure diagram of existing support device as shown in Figure 1, including crank 1, main leg 11, interlocking bar 12 and secondary leg 13,
The main leg 11 and secondary leg 13 are respectively arranged in the both sides of trailer, are connected by the interlocking bar 12, real by crank described in rocking-turn 1
Now linkage lifting, the drawback is that：Crank is placed in supporting leg one side, bad fixation；Crank is connected with supporting leg inboard leadscrews transmission device,
It is whole to bear a heavy burden greatly, lightweight demand can not be met.
Utility model content
It is simple in structure, at low cost the utility model discloses a kind of central axle support device, it can realize auto-lock function,
It is easy to use, it accords with the demands of the market.
The utility model is achieved through the following technical solutions：
A kind of central axle support device, including crank, shaft, supporting leg, connecting plate, bearing, bolt, jack, the supporting leg
Top is equipped with the crank, and the crank is fixedly connected with shaft, and the shaft is equipped with a limit hole, is set below the shaft
Have the jack, the jack is fixed on the supporting leg, and the jack is fixedly connected with bolt with chain, the jack just on
Side is the limit hole, and two bore dias are identical, and slightly larger than the diameter of the bolt, the supporting leg back side is equipped with the connection
Plate, bottom are equipped with the bearing.
Preferably, the connecting plate is connected using fixing bolt with trailer.
Preferably, the shaft directly drives the supporting leg internal gear and rotates.
Compared with prior art, the beneficial effects of the utility model are：
1st, the crank of the utility model is placed at the top of supporting leg, directly drives the rotation of supporting leg internal gear, eliminates leading screw biography
Dynamic device, simple in structure, manufacture is at low cost, has adapted to market to the light-weighted demand of trailer heavy burden, has met communications and transportation row
The development trend of industry；
2nd, the Plug Design of the utility model can realize self-locking, during preventing that trailer from travelling, cause to turn due to jolting
Axis rotates so that the slow lifting of supporting leg；
3rd, the utility model meets regulations of the national standard GB1589 to central axle sedan-chair fortune vehicle, caters to market trend, and prospect is extensive,
As country exits policy to the time limit of old-fashioned sedan-chair fortune vehicle (superelevation, ultra-wide, overlength), the utility model will increasingly obtain market
Favor.

Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings：
A kind of central axle support device, including crank 1, shaft 2, supporting leg 3, connecting plate 4, bearing 5, bolt 6, jack 7, institute
3 top of supporting leg is stated equipped with the crank 1, the crank 1 is fixedly connected with shaft 2, and the shaft 2 is equipped with a limit hole, institute
It states 2 lower section of shaft and is equipped with the jack 7, the jack 7 is fixed on the supporting leg 3, and the jack 7 is consolidated with bolt 6 with chain
Fixed connection, 7 surface of jack is the limit hole, and two bore dias are identical, and slightly larger than the diameter of the bolt 6, institute
3 back side of supporting leg is stated equipped with the connecting plate 4, bottom is equipped with the bearing 5.
The connecting plate 4 is connected using fixing bolt with trailer.
The shaft 2 directly drives 3 internal gear of supporting leg and rotates.
When the supporting leg 3 need not be lifted, the crank 1 is gone into 3 back side of supporting leg, the bolt 6 is inserted into
In the limit hole, you can realize auto-lock function.
The above only expresses the embodiment of the utility model, and description is more specific and in detail, but can not be because
This and be interpreted as the limitation to the utility model patent scope, within the spirit and principle of the utility model, made appoint
What modification, equivalent substitution, improvement etc., should be included within the scope of protection of this utility model, the guarantor of the utility model patent
Shield scope should be determined by the appended claims.
