[0030] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0031] The following first describes in detail the rotary U-turn device for heavy vehicles according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0032] refer to Figure 1 , Figure 1 A front view of a rotary turning device for a heavy vehicle according to an embodiment of the utility model is shown.

[0033] like Figure 1 As shown, the heavy vehicle rotary turning device (hereinafter referred to as the rotary turning device) according to the embodiment of the utility model comprises: a vehicle loading platform 100, a plurality of driving mechanisms 200 and an intermediate rotary mechanism 300. The vehicle loading platform 100 comprises a first side (such as Figure 1 The first side 130 of the vehicle carrier and the second side (such as Figure 1 The surface of the first side is used to contact the heavy vehicle 600. A plurality of driving mechanisms 200 are arranged on the second side of the vehicle platform 100 and are located in the circumferential direction of the vehicle platform 100. The driving mechanisms 200 are used to drive the vehicle platform 100 to rotate clockwise or counterclockwise. The intermediate rotating mechanism 300 is arranged on the second side of the center of the vehicle platform 100. The intermediate rotating mechanism 300 includes a rotating shaft 310. One end of the rotating shaft 310 is connected to the vehicle platform 100, and the other end is used to connect to the ground. The rotation center of the vehicle platform 100 is fixed on the rotating shaft 310.

[0034] Specifically, by arranging multiple driving mechanisms 200 on the circumference of the vehicle platform 100 and using the intermediate rotating mechanism 300 at the center of the vehicle platform 100 as a rotating fulcrum, the heavy vehicle 600 can be turned around. At the same time, multiple driving mechanisms 200 increase the contact points and contact areas between the turning device and the ground, avoiding the problem of unbalanced load or uneven force points of the heavy vehicle 600 on the vehicle platform 100, and reducing the ground resistance of the turning device when rotating.

[0035] Compared with the traditional solution, the utility model adopts the arrangement form of using the intermediate rotary mechanism 300 as the rotary fulcrum and the peripheral drive, which can further reduce the overall height so that the overall structure can be designed to be lightweight. In addition, the intermediate rotary mechanism 300 only bears horizontal force and has good adaptability to working conditions. At the same time, the components in the rotary turning device are relatively independent, which is quick to install and convenient for later maintenance.

[0036] Combination Figure 1 , and refer to Figure 2 , Figure 2 A top view of a vehicle loading platform of a rotary turning device for a heavy vehicle according to an embodiment of the utility model is shown.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the vehicle platform 100 is a frame structure, the frame structure includes a plurality of longitudinal beams 110 and transverse beams 120 arranged perpendicular to each other, and the driving mechanism 200 is arranged at the bottom of the frame structure. The vehicle platform 100 is composed of a plurality of longitudinal beams 110 and a plurality of transverse beams 120, and has a simple structure and a strong bearing capacity.

[0038] like Figure 2 As shown, in one embodiment of the present invention, the cross beam 120 is disposed between the two outermost longitudinal beams 110 to form a lattice structure with the longitudinal beams 110, so as to improve the load-bearing capacity of the vehicle platform 100. The load of the heavy vehicle 600 is relatively large, and the longitudinal beams 110 and the cross beams 120 form a lattice structure, which can effectively prevent the vehicle platform 100 from being damaged and deformed without increasing consumables.

[0039] like Figure 2 As shown, in one embodiment of the present invention, the cross beam 120 and the longitudinal beam 110 are steel structural material parts. Among them, the steel structural material parts are high in strength, light in weight, not easy to deform, can bear a large load, have strong durability, and reduce the weight of the vehicle platform 100 and the power consumption of the rotary turning device when rotating.

[0040] refer to Figure 3 and Figure 4 , Figure 3 A top view of a rotary turning device for a heavy vehicle according to an embodiment of the utility model is shown. Figure 4Another top view of the rotary turning device for a heavy vehicle according to an embodiment of the utility model is shown.

[0041] like Figure 3 and Figure 4 As shown, the driving mechanism 200 includes: two sets of symmetrically arranged driving wheel groups and a plurality of slave driving wheels 220. Each driving wheel group includes two main driving wheels 210. The plurality of slave driving wheels 220 are evenly arranged on the circumference of the vehicle platform 100 and rotate under the drive of the main driving wheel 210. The main driving wheel 210 provides the main driving force, and the plurality of slave driving wheels 220 are used to increase the force points between the vehicle platform 100 and the ground and increase the contact area with the ground, which can not only ensure the stability of the vehicle platform 100 and prevent the structural deformation of the rotary turning device, but also reduce the rolling resistance of the main driving wheel 210.

[0042] like Figure 2 and Figure 3 As shown, in one embodiment of the present invention, multiple longitudinal beams 110 are symmetrically arranged at length intervals, so that the extension line of the connection line between the ends of the multiple longitudinal beams 110 is a circle. The longitudinal beams 110 can be arranged from short to long from both sides to the middle, so that the ends of the longitudinal beams 110 are on a circular contour, the main driving wheel 210 and the secondary driving wheel 220 are arranged on a circle, ensuring that the rotation trajectory of the rotary turning device is a circle, and preventing the rotary turning device from deviating from the installation position.

[0043] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the rotary turning device further comprises a plurality of supporting wheels 230, and the plurality of supporting wheels 230 are suspended on the longitudinal beam (such as Figure 2 When the heavy vehicle 600 deviates from the center of the vehicle platform 100 and squeezes the vehicle platform 100 on one side, the support wheel 230 is forced to contact the ground to play a supporting role. The support wheel 230 can effectively prevent the structural deformation caused by the vehicle 600 in different positions of the turning device, and does not affect the turning of the vehicle 600.

[0044] The support wheel 230 is initially in a suspended state. When the heavy vehicle 600 is not at the vehicle entrance or vehicle exit preset by the vehicle loading platform 100, and the heavy vehicle 600 needs to pass through the rotary turning device (such as Figure 4 As shown in the figure, the heavy vehicle 600 may squeeze the vehicle platform 100 on one side, and the support wheel 230 will change from the suspended state to the grounded state due to the force, increasing the force points between the vehicle platform 100 and the ground, thereby protecting the rotary turning device. When the heavy vehicle 600 drives away, the support wheel 230 returns to the suspended state.

[0045] like Figure 1 and Figure 3As shown, in one embodiment of the utility model, the rotary turning device further includes a mounting base 400, which is disposed on the driving mechanism 200, the supporting wheel 230, and the intermediate rotary mechanism 300, and is detachably connected to the vehicle carrier 100. By providing the mounting base 400, the driving mechanism 200, the supporting wheel 230, and the intermediate rotary mechanism 300 can be quickly assembled and disassembled, and are convenient for maintenance.

[0046] like Figure 1 As shown, in one embodiment of the utility model, the rotary turning device further includes a vehicle bearing mechanism 500, which is in the shape of a flatbed and is laid on the first side of the vehicle platform 100 to receive the heavy vehicle 600. The vehicle platform 100 is composed of steel structural material pieces placed transversely and longitudinally, and cannot directly carry the heavy vehicle 600. By providing the vehicle bearing mechanism 500, the contact area between the heavy vehicle 600 and the vehicle platform 100 can be increased, and the vehicle platform 100 can be subjected to uniform force to avoid deformation of the vehicle platform 100.

[0047] In one embodiment of the utility model, the intermediate rotating mechanism 300 further includes a bearing (not shown), which is disposed on the rotating shaft 310 and has a gap between the bearing and the rotating shaft 310 for reducing friction. The appropriate gap between the bearing and the rotating shaft 310 can also improve the rigidity and positioning accuracy of the bearing and extend the service life of the bearing.

[0048] In one embodiment of the present invention, the vehicle can Figure 3 to Figure 4 The angle shown in the figure enters the rotary turning device. Depending on the vehicle size and the parking position of the vehicle, the angle at which the vehicle enters the rotary turning device can also have any inclination angle different from the angle in the figure, for example, 45 degrees, 90 degrees, or 135 degrees, which is not the only limitation in the present utility model.

[0049] In one embodiment of the present invention, the maximum vehicle that the rotary turning device can carry is 16,500 mm in length and 17 tons in weight, which can be applicable to most conventional container trucks and vehicles of the following specifications. In other embodiments, the rotary turning device can also be made of materials of different specifications to be applicable to different vehicles, which is not limited in the present invention.

[0050] In summary, the rotary turning device for heavy vehicles according to the embodiment of the utility model can realize the rotary turning function of heavy vehicles, solving the problem of the difficulty of heavy vehicles turning. In addition, it can avoid the problem of overload or uneven force points of heavy vehicles on the vehicle loading platform. At the same time, the rotary turning device adopts a design of four-sided drive and middle rotary bearing to restrain horizontal force. The overall weight is light, the strength is high, the structure is simple, not easy to deform, and the various components are quick to disassemble and assemble, which is convenient for maintenance.
