[0043] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0044] See Figure 1 As shown;

[0045] This embodiment provides a trolley transition device, which is disposed between the base frame 10 and the general-purpose dummy trolley. The transition device includes:

[0046] Crossbeam 1, the bottom of crossbeam 1 is connected to a general-purpose dummy trolley via dummy trolley connecting seat 2; and

[0047] The rotating support structure 3 is located at the middle position of the upper part of the crossbeam 1, and the central shaft 11 of the base frame 10 extends into the rotating support structure 3.

[0048] Adjustable support structures 5 for side beams are provided at both ends of the crossbeam 1 and at the bottom surface of the end of the base frame 10. The adjustable support structures 5 for side beams are used to support the inclined base frame 10 when it is transported through bends.

[0049] Specifically, this embodiment discloses a transition device suitable for the transition connection between the chassis 10 and a universal dummy trolley, so that the dummy trolley can be used for various types of chassis transportation. It mainly includes a crossbeam 1, with a dummy trolley connecting seat 2 at the bottom of the crossbeam 1 for connecting the universal dummy trolley, and a rotating support structure 3 on the upper part of the crossbeam 1 to accommodate and support the central shaft 11 of the chassis 10. The rotating support structure 3 in this embodiment not only supports the center position of the chassis 10, but also allows the central shaft 11 to rotate relative to the rotating support structure 3, making it suitable for vehicle turning. Simultaneously, since the chassis 10 may tilt when the vehicle turns, adjustable side beam support structures 5 are provided at both ends of the crossbeam 1 in this embodiment to support the corresponding ends of the tilted chassis 10.

[0050] Preferably, in this embodiment, the bottom center of the crossbeam 1 has a dummy trolley connecting seat 2, and the two ends of the bottom of the crossbeam 1 are provided with dummy trolley side support transition plates 6.

[0051] More specifically, the dummy trolley connecting seat 2 in this embodiment includes a first mounting plate 201 fixed to the bottom of the crossbeam 1 by bolts; and a bottom support column 202 fixed to the first mounting plate 201, with a second mounting plate 203 provided at the bottom of the bottom support column 202.

[0052] The second mounting plate 203 is fixed to the corresponding position of the general dummy trolley by bolts.

[0053] First, in order to connect with the universal dummy trolley, the transition device in this embodiment is designed with the dummy trolley connecting seat 2 of this embodiment.

[0054] This embodiment further defines the specific structure of the dummy trolley connecting seat 2, so as to further illustrate the connection structure between the crossbeam 1 and the universal dummy trolley. Specifically, the dummy trolley connecting seat 2 in this embodiment is designed as a bottom support column 202 that supports downwards and a second mounting plate 203 that connects to the universal dummy trolley. It is assembled and fixed to the universal dummy trolley by the second mounting plate 203 and bolts. At the same time, in order to cooperate with the mechanism on the side of the universal dummy trolley, the bottom ends of the crossbeam 1 in this embodiment are also provided with dummy trolley side support transition plates 6.

[0055] Preferably, the rotating support structure 3 of this embodiment includes: a central column 301 fixedly connected to the crossbeam 1, the central column 301 having a cavity; a spindle protective sleeve 302 located inside the central column 301, the spindle protective sleeve 302 being sleeved on the outside of the central shaft 11 of the base frame 10, and the spindle protective sleeve 302 being fixedly connected to the central shaft 11 of the base frame 10 by bolts to position and fix the spindle protective sleeve 302 and the central shaft 11 of the base frame 10;

[0056] Both the central shaft 11 and the mandrel protective sleeve 302 extend into the cavity of the central column 301, and the mandrel protective sleeve 302 can rotate relative to the central column 301.

[0057] This embodiment further defines the specific structure and connection relationship of the rotating support structure 3. First, the spindle protective sleeve 302 of this embodiment is fixed to the outside of the central shaft 11 of the base frame 10. The two are fixed together by bolts or other fasteners, so that the spindle protective sleeve 302 will not rotate relative to the central shaft 11. Then, the central shaft 11 with the spindle protective sleeve 302 is embedded into the cavity of the central column 301. The rotational cooperation between the spindle protective sleeve 302 and the central column 301 realizes the rotational requirements when the vehicle turns. The spindle protective sleeve 302, which rotates relative to the central column 301, can achieve the purpose of short-distance transportation within the factory without causing wear on the steel structure of the vehicle body.

[0058] Secondly, in order to further support the middle positions on both sides of the base frame 10, a base frame support structure 4 is provided on the upper part of the crossbeam 1 and symmetrically arranged on both sides of the central column 301 in this embodiment.

[0059] The base frame support structure 4 is used to support the frame 10 located between the central column 301 and the adjustable support structure 5 of the side beam.

[0060] More specifically, the base support structure 4 of this embodiment includes a base support column 401 that is assembled and fixed to the crossbeam 1 via a third mounting plate; and a base support plate 402 fixed to the upper end of the base support column 401. Preferably, a nylon plate 403 with a thickness of 30mm is provided between the base support plate 402 and the base frame 10 in this embodiment.

[0061] The adjustable support structure 5 of the side beam in this embodiment includes a threaded seat 501 fixed to the position of the crossbeam 1 near its end; and a support stud 502 threadedly connected to the threaded seat 501.

[0062] The upper end of the support stud 502 is the stud end 503, and a certain amount of space is reserved between the stud end 503 and the bottom of the base frame side beam.

[0063] In this embodiment, the size of the movable space is adjusted by rotating the support stud 502. During operation, the size of the movable space is 15mm.

[0064] When in use, each trolley needs to be equipped with two transition devices of this application. After the vehicle is lowered, the upper end of the adjustable support structure 5 of the side beam is adjusted to be about 15mm away from the side beam, so as to support the vehicle body when the vehicle tilts during turning.

[0065] In the above technical solution, the vehicle-mounted transition device provided by this utility model has the following features:

[0066] Beneficial effects:

[0067] The transition device of this utility model can be used for the internal transportation and circulation of special vehicles in the factory, and can meet the transportation and circulation needs. Among them, some of the spindle protective sleeves can be borrowed by other processes due to their good protective effect.

[0068] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
