Description

Technical Field

[0001] The invention belongs to the field of locomotive track changing, and in particular relates to a track gauge changing turnover frame. Background Art

[0002] Due to the inconsistency between vehicle and line gauges, the existing line gauge is often unable to meet the needs of vehicle transfer under vehicle traffic conditions.

[0003] At present, the transportation when the vehicle does not match the track gauge of the line relies on flatbed trucks. Due to the excessive height, this method is not conducive to the application of whole vehicle transportation.

[0004] Therefore, it is necessary to invent a variable gauge turnover frame to ensure the smooth transfer of the whole vehicle in the case of gauge mismatch without exceeding the limit and meet the requirements for unloading the whole vehicle on the turnover frame. Summary of the invention

[0005] The purpose of the present invention is to provide a variable gauge turnover frame to solve the problem that the gauge of the whole vehicle and the line do not match during transportation, realize the smooth transportation of the whole vehicle, and adapt to various application scenarios of different gauges and vehicle bodies.

[0006] Summary of the invention of the present invention is as follows:

[0007] A variable gauge turnaround frame, comprising a turnaround frame frame, running wheels and a support system;

[0008] The revolving frame is composed of a plurality of longitudinal beams in line with the track direction and a plurality of transverse beams perpendicular to the track.

[0009] The running wheels are symmetrically mounted at the four corners of the revolving frame and between the longitudinal beams at the two side edges, and the distance between the running wheels symmetrical on both sides along the track direction matches the track distance;

[0010] The support system includes a plurality of groups of support devices symmetrically arranged on both sides of the revolving frame along the track direction, wherein the support devices symmetrically arranged on the left and right sides along the track direction match the distance between the pairs of wheels in the width direction of the vehicle, and the front and rear support devices can form an overall support for vehicles with different wheelbases.

[0011] Furthermore, each group of support devices includes a number of support members distributed at a certain distance along the track direction, and adjacent support members support a wheel. Different spacings are formed between adjacent support members of each group of support devices and several adjacent support members of another group of support devices on the same side along the track direction to meet different vehicle wheelbases.

[0012] Furthermore, the support is in the shape of a wheel disc, suspended and fixed between the longitudinal beams, and the circumferential surfaces of adjacent support members are tangent to the circumferential surface of the wheel to form a support. The use of circular surface tangent facilitates the adjustment of the wheel on the transfer rack. Compared with other support methods, the wheel disc-shaped support has stronger pressure bearing capacity, and the cross-section support avoids rigid collision damage.

[0013] Furthermore, the support member is installed between the longitudinal beams on the inner side of the running wheel by means of bearings.

[0014] Furthermore, the support device supports the wheel and ensures that the wheel is suspended relative to the transport track surface. The distance between adjacent support members in each group of support devices is 60%-70% of the required supported wheel diameter. By adjusting the size and spacing of the support members, the wheel is ensured not to contact the track. The distance between the support members is based on the distance between the centers of the support members. The distance between the support members is limited, and the wheel diameter can be effectively supported. When the distance is small, the support range is too narrow and the support is unstable. When the distance is too large, the wheel is easy to contact the track surface. Furthermore, each group of support devices is installed in a support frame, and the support frame is installed in a space formed between the longitudinal beam and the cross beam. Support reinforcement ribs are arranged between adjacent support members. The support frame is arranged to disperse the pressure of the support member to the support frame, thereby improving the pressure bearing capacity. At the same time, if the support member is damaged, it is not easy to damage the revolving frame. The support member can be replaced by replacing the support frame. The support reinforcement ribs and the support members on both sides can form a three-point support for the vehicle body wheel, further improving the stability of the support, thereby improving the load-bearing capacity and service life of the variable track gauge revolving frame.

[0015] Furthermore, traction members are provided at the middle of the front and rear sides of the variable gauge revolving frame along the track direction, and power traction can be achieved through the traction members to facilitate the operation of the revolving frame.

[0016] Furthermore, multiple rows of support devices are installed according to various wheel track requirements of the vehicle body, and the support devices perpendicular to the track direction are arranged according to various spacings, which can be suitable for vehicle bodies of different widths.

[0017] In one embodiment of the present invention, each group of supporting devices includes three supporting members, which are supported in cooperation with other supporting devices on the same side to be applicable to three different vehicle wheelbases.

[0018] Due to the adoption of the above scheme, the beneficial effects of the present invention are as follows: the present invention provides a variable-gauge turnover frame, which can realize the transfer of the whole vehicle in the case of gauge mismatch, and the support device is arranged to effectively support the transfer vehicle, thereby meeting the load-bearing requirements, and by arranging multiple groups of running wheels and support devices, each group of support devices is provided with multiple support members, thereby realizing the transfer of bogie vehicles with different wheel gauges and wheelbases on tracks with different gauges.

[0024] Example 1

[0025] A variable gauge turnaround frame, comprising a turnaround frame frame, running wheels and a support system;

[0026] like Figure 1 and Figure 2 As shown, the revolving frame structure includes a structure that is consistent with the track direction and Figure 1 The first longitudinal beam 1, the second longitudinal beam 2, the third longitudinal beam 3, the fourth longitudinal beam 4, the fifth longitudinal beam 5, and the sixth longitudinal beam 6 are arranged from top to bottom; the longitudinal beams are connected by a vertical connection with the track. Figure 1 The first cross beam 7, the second cross beam 8, the third cross beam 9 and the fourth cross beam 10 are fixed from left to right, the first cross beam 7 and the fourth cross beam 10 are respectively located at the two ends of each longitudinal beam, and the second cross beam 8 and the third cross beam 9 are respectively arranged at a certain distance from the first cross beam 7 and the fourth cross beam 10. The cross beams and the longitudinal beams can be selected from channel steel.

[0027] There are four running wheels 11 installed at the four corners of the revolving frame, two of which are located between the first longitudinal beam 1 and the second longitudinal beam 2, and the other two are located between the fifth longitudinal beam 5 and the sixth longitudinal beam 6. The distance between the running wheels 11 symmetrical on both sides along the track direction matches the required track distance.

[0028] The support system includes four groups of support devices, two of which are respectively installed in the spaces on both sides of the second longitudinal beam 2, the third longitudinal beam 3 and each cross beam, and the other two groups are installed in the spaces on both sides of the fourth longitudinal beam 4, the fifth longitudinal beam 5 and each cross beam. Each group of support devices is symmetrically arranged. The support devices symmetrically arranged along the track direction match the distance between the pairs of wheels in the width direction of the vehicle. The support device is installed in the support frame 12, and the support frame 12 is installed in the space formed between the longitudinal beam and the cross beam. Each group of support devices includes three support members 13, which are wheel disc-shaped, made of rigid material, and installed between the support frame 12 and the longitudinal beam through bearings. The support members 13 are distributed at a certain distance along the track direction, and support reinforcement ribs 14 are arranged between adjacent support members 13.

[0029] Adjacent support members 13 support a wheel to ensure that the wheel is suspended relative to the transport track surface. The distance between adjacent support members is 60%-70% of the required wheel diameter. The distance between the support members is based on the line between the centers of the wheel discs. Different spacings are formed between adjacent support members of each group of support devices and several adjacent support members 13 of another group of support devices on the same side along the track direction to meet different vehicle wheelbases. Figure 2 As shown, in this embodiment, three different vehicle wheelbases can be met, with the distance between the centers of the farthest adjacent support members 13 on both sides being the vehicle wheelbase one, the distance between the centers of the adjacent support members 13 from the farthest end on one side to the nearest end on the other side being the vehicle wheelbase two, and the distance between the centers of the adjacent support members 13 at the nearest ends on both sides being the vehicle wheelbase three.

[0030] On the turnover frame, a traction member 15 is installed at the center of the first cross beam 7 and the fourth cross beam 10, and the traction member 15 can be a train coupler.

[0031] In a preferred embodiment of the invention, multiple longitudinal beams can be added to install multiple sets of running wheels with different wheel widths according to the requirements of tracks with different track gauges; or multiple rows of support devices can be installed according to the various wheel width requirements of the vehicle body, so that the support devices perpendicular to the track direction can be arranged according to various spacings, which can be suitable for vehicle bodies with different widths.

[0032] The implementation process of this embodiment is as follows:

[0033] Two variable gauge revolving frames are operated on the standard gauge line one after the other using running wheels. The bogie of the car body is suspended on the variable gauge revolving frame by an overhead crane. The bogie is placed between the support devices that meet the appropriate wheelbase, and the wheels are located between the supports to form a support. The car body is lifted by the car lifting machine and falls on the bogie. Finally, it is connected to the train hook above the revolving frame through the road-rail dual-purpose vehicle for traction. In this way, the vehicle that does not meet the standard gauge line gauge is changed through the variable gauge revolving frame. The use of this variable gauge revolving frame can form a stable support for the car body and is suitable for car bodies with different wheelbases.

[0034] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
