Fluctuated relative to road wheel 7, support base 1 is contacted so that itself and road wheel 7 are propped up jointly after having floating downwards with ground
Support the support level of part to be supported and depart from the free position on ground after floating upwards.Axis is provided with support base 1 vertically to prolong
The screw rod 5 stretched, elastic floating support includes the flat spring 8 that one end is connected on wheel carrier 4, the other end is connected on screw rod 5, screw rod
5 periphery is arranged with sleeve 6 in the lower section of flat spring 8, and the threaded upper ends of screw rod 5 are connected with nut, screw rod 5, sleeve 6 and nut
Form vertical connecting rod together, the end sleeve of flat spring 8 on the screw portion between nut and sleeve 6, nut and set
Cylinder 6 is formed and flat spring block coordinates about 8 upper stop part and lower stop part respectively.
Support base 1 includes the chassis supports part 2 and vertical mounting cylinder part 3 that weld together, and wheel carrier 4 passes through bullet
Property float support is connected on chassis supports part 2.Height adjusting structure includes rolling assembling in the rotation on mounting cylinder part 3
Regulating part and the leading screw 9 vertically extending with the axis that rotation regulating part screw thread coordinates, the lower end of leading screw 9 be provided with for
The guide pad 10 coordinated with the upper and lower guiding movement of the endoporus of mounting cylinder causes greatly leading screw 9 with the lower end amplitude of fluctuation for preventing leading screw 9
Lower end directly rubbed with the inner hole wall directly contact of mounting cylinder part 3, guide pad 10 is connected to leading screw 9 by fixing screws 11
Lower end, be provided with packing ring 12 between the lower surface of leading screw 9 and fixing screws 11, the endoporus of guide pad 10 and mounting cylinder part 3
Gap coordinates between wall, and gap is 1mm, and both can mutually rotate.Rotation regulating part includes being linked together by bolt 17
Handwheel part 14 and the nut portion 16 for coordinating with the screw thread of leading screw 9, nut portion 16 are hierarchic structure, on handwheel part 14
With a perforation passed through up and down for the path section of nut portion 16, handwheel part 14 includes the path section with nut portion 16
The auxiliary section 15 of cooperation and the handwheel for staff force, the cascaded surface of nut portion 16 and the mating part 15 of handwheel part 14
Upper surface is engaged.Thrust bearing 20 is provided with mounting cylinder part 3, the path section of nut portion 16 passes through thrust bearing 20
Rotation is installed in mounting cylinder part 3, and the lower end of the path section of nut portion 16 is equipped with annular groove 18, horizontal on mounting cylinder part 3
To caging bolt 19 is provided with, caging bolt forms the vertically movable position limiting structure of limitation rotation regulating part, the groove width of annular groove 18
Diameter with caging bolt 19 is adapted, and caging bolt 19 coordinates so as to rotate regulating part relative to mounting cylinder part with annular groove 18
3 can not be moved up and down, i.e., when caging bolt 19 is not screwed, rotation regulating part freely can be rotated to adjust around its axis
The height of support member 23 is saved, screwing caging bolt 19 after height is adjusted locks the position of support member 23.Mounting cylinder part 3
Ledge structure 13 is provided with inwall, the step surface of ledge structure 13 is formed for matching somebody with somebody with the upper and lower block in the upper surface of guide pad 10
Close to limit the confined planes of the upward maximum displacement of support member 23.
The upper end of leading screw 9 is connected with cushion block 21, and support member 23 is connected on cushion block 21 by connecting bolt 22, and cushion block 21 has
There is the support mating surface being engaged with the lower surface support of support member 23, support the area of mating surface transversal more than leading screw 9
Area.Cushion block 21 plays increase supporting surface and wear-resisting effect, and for loss of weight, support member 23 is made for aluminium alloy, pad
Block 21 can avoid the directly contact of support member 23 and leading screw 9, because the cross-sectional area of leading screw 9 is small, if support member 23 is direct
Contacted with leading screw 9, after the stress of support member 23, support member 23 is big with the contact surface stress of leading screw 9, is easily damaged.Support member 23 with
Gap coordinates between connecting bolt 22, and support member 23 is made by connecting bolt 22 is somewhat unscrewed around 360 degree of rotations of connecting bolt,
Using more convenient.The upper surface of support member 23 is provided with the nylon cushion 24 for being engaged with part to be supported, protects and treats
Support surface will not be scratched or damage.
A kind of course of work of support frame of the invention is：Part to be supported is bus bar canister in the present embodiment, when bus bar canister pair
When connecing, the support frame is moved to by correct position by road wheel 7.In the case of not load-bearing, the lower surface of support base 1 away from
15mm is that the lower surface of support base 1 is 15mm apart from ground from the ground.Rotation hand wheel 14 makes the nylon of the upper end of support member 23
Pad 24 is contacted with bus bar canister, continues rotation hand wheel 14, and flat spring 8 is deformed, and support base 1 is moved down.When bus bar canister
During lighter in weight, continue rotation hand wheel 14, support base 1 moves down, but do not contact with ground, still positioned at suspension
State, now adjusting handle 14 until support member 23 reach correct position, support member 23 is locked by screwing caging bolt 19, and
Braking vane on each wheel carrier 4 is locked to fix the position of road wheel 7, rely only on road wheel 7 and be supported.When the weight of bus bar canister
When measuring heavier, during rotation hand wheel 14, when flat spring 8 is when weighing more than setting value, support base 1 can connect with ground
Touch, now support base 1 is located at support level, support base 1 and road wheel 7 are supported to bus bar canister together, play rigid branch
The effect of support, rotation hand wheel 14 is located at suitably height up to support member 23, screws on caging bolt 19 and locking wheel carrier 4
Braking vane, the position to the support frame is fixed, and now the support frame increased supporting surface greatly with the contact area on ground
Product, stabilization is difficult to tumble.After bus bar canister installation, opposite direction rotation hand wheel 14 in the presence of flat spring 8, supports bottom
Seat 1 can reset upwards automatically, support base 1 is in suspended state, be easy to move the support frame, by the support frame from bus bar canister
The lower storeroom for removing and shifting support frame onto, using more convenient.
In other embodiments of the invention, it is also possible to be not provided with height adjusting structure, when now part to be supported is heavier, treat
It is positioned over when on support frame, and support base is floated contacted with ground positioned at support level downwards；The end of flat spring can also be straight
It is connected in support base in succession, for example, is connected on mounting cylinder part；Elastic floating support can also include screw rod and be sheathed on
Extension spring on screw rod, now with the connecting rod being sheathed on screw rod, now extension spring is located on the screw rod below connecting rod wheel carrier；
Elastic floating support can also include screw rod and the stage clip being sheathed on screw rod, and now wheel carrier has the connection being sheathed on screw rod
Bar, now stage clip is on the screw rod between connecting rod and nut；Sleeve can also be replaced playing and flat spring by nut
The effect that the upper and lower block of lower surface coordinates；Position limiting structure may not be caging bolt, can be disposed on mounting cylinder part
Upper land and lower land on inner hole wall, now the lower end of nut portion be provided with and turned over the elasticity of upper and lower land snap-fit connection
Edge；Can also be adjusting nut on rotation regulating part, rather than handwheel；In the case where use is met, it is also possible to be not provided with pad
Block；The upper surface of support member can also be not provided with nylon cushion；Nylon cushion can also have rubber blanket to replace.
