Abstract
The utility model discloses a kind of Assembling bogie, comprise vehicle frame and the road wheel of circumference setting below vehicle frame, described vehicle frame is provided with stop motion mechnism, described stop motion mechnism comprise the upper downward-extension assembled with bolster screw screw rod, with screw rod bottom rotates assemble also can under screw rod promotes the base of kiss the earth, described base has the bearing surface coordinated with ground supports.Assembling bogie of the present utility model in use, rotate the screw rod be assemblied on vehicle frame, screw rod rotates and drives the base being arranged on its lower end to move in direction earthward, after base and earth surface, continuing rotating screw bar makes the vehicle frame of dolly be supported by screw rod, and realize the stop to Assembling bogie by the friction force between base and ground, stopping effect is good, solve existing Assembling bogie stopping effect poor, need hand steered problem, thus improve efficiency of assembling.
Description
Technical field
The utility model relates to high-tension switch gear assembling field, particularly a kind of Assembling bogie.
Background technology
The part assembling of the spring operating mechanism in high-voltage switch gear completes on Assembling bogie, Assembling bogie comprises dolly flat board, dull and stereotyped below is provided with four cardan wheels, in the fitting process of spring operating mechanism, be that requirement Assembling bogie remains static, and the stop of Assembling bogie is at present by the friction force between cardan wheel and ground.Because cardan wheel and ground are linear contact lay, so the friction force between cardan wheel and ground is less, less friction force can not carry out stop well to Assembling bogie, needs artificially hand steered mode to make Assembling bogie stop, reduces the efficiency of assembling of spring operating mechanism.
Summary of the invention
The purpose of this utility model is to provide a kind of Assembling bogie improving the efficiency of assembling of spring operating mechanism.
To achieve these goals, the utility model Assembling bogie adopts following technical scheme: comprise vehicle frame and the road wheel of circumference setting below vehicle frame, described vehicle frame is provided with stop motion mechnism, described stop motion mechnism comprise the upper downward-extension assembled with bolster screw screw rod, with screw rod bottom rotates assemble also can under screw rod promotes the base of kiss the earth, described base has the bearing surface coordinated with ground supports.
Described screw rod is screw rod, and described screw rod upper end is provided with six prism structures for coordinating with spanner.
The bottom of described screw rod is radially convexly equipped with annular boss, and described base is provided with the mounting hole for installing screw rod, is provided with the bearing of the pivot axis around screw rod between the annular boss of described screw rod and mounting hole.
The upper end of described base is provided with flange, and described flange is equipped with for the baffle plate to screw rod block.
Flange on described base is C type flange.
Described stop motion mechnism is spaced two of left and right.
The lower end of described base is provided with rubber pad.
Described road wheel is cardan wheel.
The beneficial effects of the utility model are: in the fitting process of spring operating mechanism, when needing Assembling bogie stop, rotate the screw rod be assemblied on vehicle frame, screw rod rotates and drives the base being arranged on its lower end to move in direction earthward, after base and earth surface, continuing rotating screw bar makes the vehicle frame of dolly be supported by screw rod, the stop to Assembling bogie is realized by the friction force between base and ground, area of contact between base and ground is large, friction force is large, do not need to carry out hand steered just can to Assembling bogie stop, thus improve efficiency of assembling.

Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 2.
Detailed description of the invention
Embodiment of the present utility model, as Figure 1-3: this Assembling bogie, four cardan wheels 3 comprising vehicle frame 2 and arrange along the circumference of vehicle frame 2, vehicle frame 2 is provided with a flat board 1, dull and stereotyped 1 upper left right septum is provided with two stop motion mechnisms 4, stop motion mechnism 4 is between two cardan wheels 3 of fore-and-aft direction, stop motion mechnism 4 comprises spiral and is assemblied in the screw rod 41 of the upper downward-extension on dull and stereotyped 1 and rotates with screw rod 41 bottom the base 45 assembled, screw rod 41 upper end is provided with six prism structures 410 for coordinating with spanner, screw rod 41 bottom is radially convexly equipped with annular boss 411.Base 45 offers opening up mounting hole, needle bearing 43,44 is separately installed with in the upper and lower of the annular boss 411 of screw rod 41 in mounting hole, the pivot center of needle bearing 43,44 and the coaxial of screw rod 41, the top of needle bearing 43 is provided with the baffle plate 42 for stoping needle bearing 43 and screw rod 41 to depart from from the mounting hole of base 45, and baffle plate 42 is bolted on the flange on base 45.The flange of base 45 is C type flange, makes base 45 more convenient with the handling of screw rod 41 bottom, even base 45 is located on the ground, also easily can be unloaded from screw rod side by base 45, instead of base 45 could be unloaded after being risen by screw rod 41.The lower end of base 45 is also provided with the rubber pad 46 for increasing friction force between base 45 and ground.
By Assembling bogie, spring operating mechanism to be assembled is transported to assigned address, to in the fitting process of spring operating mechanism, when needing Assembling bogie stop, six prism structures 40 are rotated with spanner, screw rod 41 rotates and drives base to move down, after base and earth surface, continue rotary screw 41, the vehicle frame 2 of Assembling bogie is supported by screw rod 41 and departs from ground, rely on the friction force between base 45 and ground to carry out stop to Assembling bogie, ensure that in fitting process, Assembling bogie is static.
In the present embodiment, screw rod realizes normal-running fit with stay bearing plate by needle bearing and is connected, and needle bearing can bear the axial force that operating mechanism is applied to screw rod, and it is more laborsaving, convenient by the needle bearing arranged, adjusting screw(rod) to be rotated; In other embodiments, needle bearing 43 also can change other types of bearings into, as deep groove ball bearing.
In other embodiments, screw rod can change leading screw into.
In other embodiments, be the assembling making Assembling bogie be applied to dissimilar spring operating mechanism, Assembling bogie can be arranged 1,3 or 4 stop motion mechnisms.
In other embodiments, according to constructional feature, the size of the parts of spring operating mechanism, can carry out adaptive change to the structure of vehicle frame, the flat board on it also can not be arranged, and the direct spiral of screw rod is assemblied on vehicle frame.
