DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0043] Reference Figure 2-Figure 9 The present application provides an auxiliary rotation operation equipment suitable for heavy tracked vehicles, including a mobile auxiliary rotation mechanism 1, a mobile lifting mechanism 2 and a mobile hydraulic pump station 313. The mobile auxiliary rotation mechanism 1 has a rotatably arranged tray 11 to support the faulty vehicle and drive the faulty vehicle to turn. The mobile lifting mechanism 2 is provided with multiple groups and is arranged at the bottom of the chassis of the faulty vehicle for supporting or lowering the faulty vehicle. During the actual steering auxiliary operation, the mobile lifting mechanism 2 preferably adopts four groups and is arranged at the four corners of the chassis of the faulty vehicle. The mobile hydraulic pump station 313 is used to provide power for the rotation of the tray 11 and the supporting and lowering operations of the mobile lifting mechanism 2.

[0044] Reference Figure 2-Figure 4 The mobile auxiliary slewing mechanism 1 also includes a main body base 12, a hydraulic motor 13, a slewing reducer 14 and a walking assembly 15. The slewing reducer 14 is installed on the main body base 12 and the output shaft is fixedly connected to the tray 11 to drive the rotation of the tray 11. When the faulty vehicle falls on the tray 11, the faulty vehicle can be turned as a whole by rotating the tray 11. The hydraulic motor 13 is installed on the main body base 12 and is connected to the slewing reducer 14 to drive the rotation of the output shaft of the slewing reducer 14. The hydraulic motor 13 is connected to the mobile hydraulic pump station 313 through a hydraulic pipeline to provide the hydraulic motor 1 3 rotation power, the walking assembly 15 is provided with multiple groups and is separately arranged on the outer wall of the main body base 12 near the bottom, and the walking assembly 15 has a roller 151 that is lifted and lowered to facilitate the walking and fixing of the main body base 12, thereby facilitating the main body base 12 to enter the bottom of the faulty vehicle, and at the same time realize the fixing of the main body base 12 during the steering operation. In a feasible embodiment, the tray 11 can be a tray body of any shape. In this embodiment, the tray 11 is preferably a disc-shaped tray body coaxially arranged with the output shaft of the rotary reducer 14. The driving connection between the hydraulic motor 13 and the rotary reducer 14 is a prior art and will not be described in detail.

[0045] Furthermore, the walking component 15 also includes a swing arm 152 and a cylinder 153. The cylinder 153 is rotatably installed at the bottom of the main base 12 and the telescopic rod is arranged toward the tray 11. One end of the swing arm 152 is rotatably connected to the telescopic rod of the cylinder 153 through a cylinder pin 4. The middle part of the swing arm 152 is rotatably installed on the outer wall of the main base 12 through the swing arm 152 pin. The roller 151 is rotatably installed on the outer wall of the other end of the swing arm 152 through a roller pin 6. The roller 151 is driven by the swing arm 152 to be set close to or away from the ground. When the tray 11 is not supported, the roller 151 can maintain a downward rotation posture under the action of the swing arm 152 and the cylinder 153, and lift the entire auxiliary rotating mechanism to leave the ground so that it can roll on the ground; when the faulty vehicle falls on the tray 11, due to the sufficiently large external force on the tray 11, the cylinder 153 is compressed and retracted, the roller 151 is lifted, and the main base 12 of the auxiliary rotating mechanism falls to the ground and is fixed, and then the faulty vehicle is driven to turn on the spot through the rotation of the tray 11.

[0046] Furthermore, a plurality of traction lugs 7 are integrally formed or welded around the bottom of the main base 12 , so that the mobile auxiliary slewing mechanism 1 can be towed by other vehicles or traction equipment after connecting a traction lock to the traction lug 7 .

[0047] Reference Figure 5-Figure 7 The mobile lifting mechanism 2 includes a jack 21, a base frame 22 and a walking assembly 23. The jack 21 is installed on the base frame 22 and is connected to the mobile hydraulic pump station 313 through a hydraulic pipeline to provide the power required for the jack 21 to work, and the extension and retraction of the jack 21 are controlled by the mobile hydraulic pump station 313, so as to lift or lower the faulty vehicle; the walking assembly 23 is installed on the base frame 22 and is divided into multiple groups. The walking assembly 23 has a roller 231 set for lifting and lowering to facilitate the walking and fixing of the base frame 22. In this embodiment, the base frame 22 is preferably a rectangular plate, and the walking assembly 23 is preferably installed with four groups arranged at the four corners at the bottom of the base frame 22.

[0048] Furthermore, walking component 23 also includes a roller frame 232, a roller bracket seat 233 and a cylinder 234. The roller bracket seat 233 is installed on the base frame 22. The installation method includes but is not limited to bolt installation or welding installation. The roller frame 232 is slidably inserted on the bottom wall of the roller bracket seat 233 outside the base frame 22. The bottom of the roller frame 232 extends out of the roller bracket seat 233. The roller 231 is rotatably installed on the bottom outer wall of the roller frame 232 through the roller pin 28. The head end of the telescopic rod of the cylinder 234 is rotated on the outer wall of the roller bracket seat 233 near the top. The end of the cylinder 234 away from the telescopic rod is rotatably installed on the bottom outer wall of the roller frame 232 through the cylinder pin 29. The roller 231 is set close to or away from the ground through the lifting of the roller frame 232. When there is no external force acting on the jack 21, under the action of the cylinder 234, the roller frame 232 and the roller 231 extend downward, lifting the entire mobile lifting mechanism 2 until it is off the ground and can then roll on the ground; when the jack 21 lifts a heavy object, the external force is transmitted to the cylinder 234 through the jack 21, the base frame 22, and the roller bracket seat 233, the telescopic rod of the cylinder 234 is retracted under the force, the roller 231 and the roller frame 232 are relatively lifted, and the base frame 22 falls to the ground, thereby realizing the fixed lifting of the jack 21.

[0049] Furthermore, a traction rod 10 is welded and fixed on the outer wall of one side of the base frame 22 , and the traction rod 10 is used for human traction and movement of the mobile jacking mechanism 2 .

[0050] Reference Figure 8 and Fig. 9 The mobile hydraulic pump station 313 is composed of a hydraulic pump station 31 and a self-propelled transfer trolley 32, which is used to provide a power source for the mobile auxiliary rotating mechanism 1 and the mobile lifting mechanism 2. The self-propelled transfer trolley 32 is a commercially available part, which is powered by a battery and has a self-propelled function. It also serves as a power source for the hydraulic pump station 31; the hydraulic pump station 31 is installed on the self-propelled transfer trolley 32. The hydraulic pump station 31 is composed of an oil tank 311, a motor pump group 312, and a control valve group 313. The control valve group 313 is installed with five groups, one of which is used to control the forward and reverse rotation of the mobile auxiliary rotating mechanism 1, and the other four groups of control valve groups 313 are used to control the extension and retraction of the four groups of mobile lifting mechanisms 2. In this embodiment, the installation and use of the motor pump group 312 and the control valve group 313 are both existing technologies and will not be described in detail.
