Description

Wheel box capable of being detached on single side

Technical Field

The utility model relates to a transport vechicle, concretely relates to can unilateral dismantle wheel case belongs to bridge engineering construction technical field.

Background

The application of the prefabricated box girder in bridge construction is common, the conventional domestic beam yard prefabricated box girder generally adopts common formworks and hydraulic formworks, and the proportion of the prefabricated box girder adopting the hydraulic formworks is higher and higher along with the improvement of the technology and the development of the industry. The existing commonly used hydraulic prefabricated box girder template is generally fixed by a bottom die, and a side die can realize transverse die opening and longitudinal movement to the next station for pouring through a hydraulic system, namely, a pedestal and the bottom die are fixed, and the side die is integrally moved and transposed. Compared with the traditional common template, the mode has the advantages of less template investment, high efficiency and the like, but the pouring stations are continuously changed, personnel and auxiliary machines are required to be changed along with the change of the stations, pouring operation is required to be carried out on each station, and the cleanness and the tidiness of the site are not guaranteed well. In order to improve the problems, the operation mode of the precast beam is changed, and a fixed side die and a walking bottom die are adopted. The novel precast box girder operation mode has the following advantages: the worker operation station position is fixed, parallel operation, mutual noninterference, and work efficiency is high, the operating cycle is short, the place is clean and tidy, clean, has improved the life and the precast beam quality of template.

The implementation of a new precast box girder operation mode and the stable transportation of the precast box girder which is not stretched are technical key points and difficulties to be solved. This approach has the following problems:

1. operation stability: the trolley has over-high running gravity center height, so that the box girder is easy to be unstable, and potential safety hazards exist;

2. maintenance convenience: the wheel set is integrated with the frame, and is not easy to disassemble and maintain when in failure.

SUMMERY OF THE UTILITY MODEL

For the problem of solving the steady transportation of not stretch-draw precast box roof beam, when reducing precast beam transportation flatcar running height, compromise the convenience requirement that the maintenance was changed to the wheelset, the utility model provides a can unilateral dismantle the wheel case.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:

a wheel box capable of being detached on one side comprises an outer connecting frame, an inner connecting frame and wheel sets, wherein the outer connecting frame and the inner connecting frame are detachably connected into a whole, the outer connecting frame and a vehicle frame are connected into a whole, and the wheel sets are connected with the inner connecting frame through wheel shafts.

But unilateral dismantlement wheel case preferred scheme passes through wedge inclined plane cooperation between outer link and the interior link, and outer link and interior link are connected as an organic whole through connecting bolt.

But unilateral dismantlement wheel case preferred scheme, inside connection frame are under the narrow structure of width, and inside connection frame includes diaphragm I and two curb plates I, and the surface is equipped with a plurality of inside connection holes, connects inside reinforcing plate on the inner wall.

But unilateral dismantlement wheel case preferred scheme, outer link is narrow structure wide down, and outer link includes diaphragm II and two curb plates II, and the surface is equipped with a plurality of outer connecting holes and shaft perforation, is connected outer reinforcing plate between outer link and the frame.

The preferred scheme of the wheel box capable of being disassembled on one side has the inclined angle of the wedge-shaped inclined plane of 9 DEG

The utility model has the advantages that:

1. the height of the frame is effectively reduced, and the stability of the transport beam is improved;

2. the reasonable wedge-shaped angle is convenient for the wheel box to be separated from the frame when being disassembled;

3. the unilateral dismantlement mode both guaranteed frame integral rigidity and be convenient for single wheelset maintenance, change.
