[0004] At present, in the production process of the middle bridge shell, the main shell part is generally manufactured first, and then various shapes required for subsequent processing are processed on the main part through operations such as drilling, milling and boring. In this process, the middle bridge shell needs to undergo a variety of different processing on multiple different processing lines, and finally assembled with other parts. In this process, the middle bridge shell needs to be transported many times, and the middle bridge shell itself is heavy, and the shape is irregular and flat, so it is usually transported using a cart with certain fixing devices. However, this mode of transportation still requires workers to move the middle bridge shell on or off the cart, which increases the workload and also has certain safety hazards, so a better transportation equipment is needed.

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, the embodiment of the utility model provides a tool for transporting a bridge housing in an automobile, comprising a bracket, a lifting device 5 arranged on the top of the bracket, and a limiting device 6 arranged in the middle of the bracket.

[0022] In this embodiment, the bracket includes a base 1, a support rod 2 and a top frame 3 which are arranged in sequence from bottom to top. The base 1 includes two seat plates arranged horizontally in parallel, with a space of at least the width of the middle bridge shell between the seat plates, and according to requirements, the space spacing can be a multiple of the width of the middle bridge shell. In this embodiment, the spacing between the seat plates is twice the width of the middle bridge shell. Three universal rollers 11 are evenly installed at equal intervals on the bottom of each seat plate, so that the bracket can slide in any direction. There are four support rods 2, and each support rod 2 is vertically arranged above the two ends of the seat plate, so that the support rods 2 on the two seat plates are symmetrical. The top frame 3 is arranged on the top of the support rod 2, so that the entire bracket forms a square frame structure, and the projection of the top frame 3 on the horizontal plane covers the area between the seat plates.

[0023] In a further solution, the top frame 3 includes two top beams 31 and two connecting beams 32. The two ends of the top beams 31 are connected to the high ends of the opposite support rods 2 so that they are horizontally arranged on the top of the support rods 2. The connecting beams 32 are arranged perpendicular to the top beams 31, that is, the connecting beams 32 are parallel to the seat plate. In this embodiment, the two connecting beams 32 are respectively connected to the positions of one quarter of the length and three quarters of the length of the two top beams 31, so that the lower part of the connecting beams 32 just corresponds to the middle of the middle bridge shell placement area. In addition, two cross beams 4 are arranged between the support rods 2 in the vertical direction and parallel to the top beams 31, and the height of the cross beams 4 is lower than the top beams 31.

[0024] In this embodiment, there are two lifting devices 5 and two limiting devices 6, wherein the lifting devices 5 are installed in parallel at the bottom of the top frame 3, and the lifting devices 5 can move the middle bridge shell up and down in the vertical direction; the limiting devices 6 are installed at the bottom of the cross beam 4 and correspond to the lifting devices 5 one by one, so as to limit the middle bridge shell in the horizontal direction.

[0025] like Figure 2 As shown, in a specific solution, the lifting device 5 includes two electric hoists 51 arranged in parallel along the seat plate direction, and the electric hoist 51 includes two steel wire ropes 52 suspended at the bottom, and the ends of the two steel wire ropes 52 at the bottom are respectively provided with hooks 54 and hanging rings 53. Further, the steel wire ropes 52 are also provided with a limit sleeve 55 on the outside, and the limit sleeve 55 is in sliding contact with the steel wire ropes 52. The inner diameter of the limit sleeve 55 is slightly larger than the total diameter of the two steel wire ropes 52, so that it can cover the two steel wire ropes 52 at the same time and can slide up and down freely.

[0026] like Figure 3As shown, since there are two cross beams 4 in this embodiment, each cross beam 4 has two parallel limit devices 6, and the connecting line between the two limit devices 6 located on the same side of the two cross beams 4 is coplanar with the connecting beam 32 in the vertical direction, so that when the middle bridge housing located below the connecting beam 32 moves in the vertical direction, its two ends will move to the position of the limit device 6. The limit device 6 includes a mechanical claw, which has two symmetrical grippers 61, and the rotation surfaces of the two grippers 61 are perpendicular to the cross beam 4. A pressure-sensitive switch 62 is also provided on the top of the area between the grippers 61, and the pressure-sensitive switch 62 drives the action of the grippers 61.

[0027] When the utility model is used, the bracket is first moved to the top of the middle bridge shell so that the connecting beam 32 is parallel to the axis of the middle bridge shell. Then the wire rope 52 is moved downward to the middle bridge shell by the electric hoist 51. After the two wire ropes 52 pass around the two sides of the middle bridge shell, they are connected from the bottom through the hook 54 and the hanging ring 53. Then the limit sleeve 55 is pulled to make the wire rope 52 in close contact with the surface of the middle bridge shell to prevent the hook 54 and the hanging ring 53 from loosening. After the two sets of electric hoists 51 are fixed to the two ends of the middle bridge shell respectively, the electric hoist 51 is started to lift the middle bridge shell upward until the middle bridge shell moves to the bottom of the crossbeam 4. Then, the ends of the two ends of the middle bridge shell are in contact with the pressure-sensitive switch 62, and the gripper 61 of the mechanical claw is controlled to close. At this time, the lifting and fixing of the middle bridge shell is completed. Since two sets of lifting devices 5 and limit devices 6 are arranged in parallel in this embodiment, two middle bridge shells can be transported at the same time. When the mobile support reaches the destination, the mechanical claw is opened manually, and then the middle bridge housing is lowered to the ground through the electric hoist 51, and the hook 54 and the hanging ring 53 are untied.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
