[0040] See also Figure 1 The embodiment of the present invention provides an emergency post-disaster rescue auxiliary vehicle, including a carrier platform 4, and auxiliary hydraulic lifting and lowering platforms 5 are arranged on both sides below the carrier platform 4. The carrier platform 4 is connected to a frame 6, and a brake-like positioning disc is arranged on the frame 6. The use of the brake-like positioning disc can effectively achieve the braking and positioning of the equipment. The housing 1 is fixed to the carrier platform 4.

[0041] For further information, see Figure 4-5 The frame 6 includes a straight convex frame 61 and a double-splayed terrain-adaptive frame 62. Two parallel vertical rods 611 are arranged on the fixed plate 2 of the straight convex frame 61, and each of the vertical rods 611 is provided with a roller controlled by a motor. The two sides of the fixed plate 2 of the double-splayed terrain-adaptive frame 62 are provided with an eight-shaped rod 621, and the eight-shaped rod 621 is rotatably arranged on the fixed plate 2, and a roller controlled by a motor is arranged below the eight-shaped rod 621. The straight convex frame 61 and the double-splayed terrain-adaptive frame 62 can cooperate to achieve more stable movement.

[0042] For further information, see Figure 2-3 The auxiliary hydraulic lifting platform 5 includes a lifting rod 51 fixed on the carrying platform 4 and a lifting mechanism 52 symmetrically distributed on the lifting rod 51; the lifting mechanism 52 includes an upper V-shaped load-bearing support arm 521 and a lower V-shaped load-bearing support arm 522 rotatably arranged on the lifting rod 51, and the V-shaped load-bearing support arm 522 has a stronger bearing capacity and can lift the entire machine. The other ends of the upper V-shaped load-bearing support arm 521 and the lower V-shaped load-bearing support arm 522 are rotatably connected to the pressure-bearing rod 523, and a pressure-bearing chassis 524 is arranged at the bottom of the pressure-bearing rod 523; the lifting mechanism 52 also includes a hydraulic rod 525, and the side of the hydraulic rod 525 close to the lifting rod 51 is concentrically arranged with the lower V-shaped load-bearing support arm 522, and the side of the hydraulic rod 525 away from the lifting rod 51 is concentrically arranged with the upper V-shaped load-bearing support arm 521. During the extension of the hydraulic rod 525, the pressure chassis 524 descends to lift up the entire device, so that the straight convex frame 61 and the double-splayed terrain-adapting frame 62 are both suspended. The hydraulic rod 525 is arranged concentrically with the lower V-shaped load-bearing support arm 522 on one side close to the lifting rod 51, and the hydraulic rod 525 is arranged concentrically with the upper V-shaped load-bearing support arm 521 on the side away from the lifting rod 51, so that the lifting can obtain a larger stroke.

[0043] During the extension of the hydraulic rod 525, the pressure chassis 524 descends to lift up the entire device, so that the straight convex frame 61 and the double eight-shaped terrain adaptation frame 62 are both suspended, and the steering mechanism can realize the steering of the frame. Figure 6-9 A steering mechanism 7 is provided in the housing 1, and the steering mechanism 7 includes a worm 71 controlled by a motor, a turbine 72 meshing with the worm 71, and a rotating shaft 73 connected to the turbine 72; the rotating shaft 73 penetrates the fixed disk 2 and is fixed thereto. The motor starts to drive the worm 71 to rotate, the worm 71 drives the turbine 72 to rotate, the turbine 72 drives the rotating shaft 73 to rotate, and the rotating shaft 73 drives the fixed disk 2 to rotate and turn it. In actual use, multiple worms 71 can be selected according to the quality of the equipment to be driven, and multiple worms 71 can simultaneously drive the turbine 72 to rotate.

[0044] Furthermore, in the actual working process, the frame cannot rotate to prevent the equipment from sliding, so the frame needs to be locked. The present invention adopts a brake-like positioning disk, a shell 1, a fixed disk 2 and a positioning mechanism 3, wherein the positioning mechanism 3 includes a central rotating frame 31 sleeved on the shell 1, a linear surrounding sleeve 32 clamped on the central rotating frame 31, a positioning rod 33 arranged on the linear surrounding sleeve 32 and a driving mechanism 34 for controlling the rotation of the central rotating frame 31; one end of the positioning rod 33 is fixed on the fixed disk 2, and the other end is provided with a positioning head 331; during the rotation of the central rotating frame 31, the positioning head 331 can lock the shell 1 to achieve positioning.

[0045] The specific working principle is: the driving mechanism 34 is started, the central rotating frame 31 rotates, and the positioning rod 33 is constrained by the linear surrounding sleeve 32 and rotates, so that the positioning head 331 is against the shell 1, so the frame is not easy to rotate, protecting the motor of the steering mechanism 7.

[0046] More specifically, the driving mechanism 34 includes a control seat 341 fixed on the fixed disk 2, a straight-moving conversion screw rod 342 rotatably arranged on the control seat 341, and a control motor 343 arranged on the control seat 341 and capable of controlling the straight-moving conversion screw rod 342; the straight-moving conversion screw rod 342 is connected to the central rotating frame 31 via a slider.

[0047] See also Figure 8-9 The control seat 341 is relatively long, and the middle part of the control seat 341 is rotatably fixed on the fixed plate 2, so as to better cooperate with the rotation of the central rotating frame 31 and prevent interference and overall jamming. The control seat 341 can drive the motor 343 and the straight conversion screw 342 to rotate slightly.

[0048] The central rotating frame 31 is formed by connecting two hollow annular disks, and a linear surrounding sleeve 32 is fixed in the gap between the annular disks. The annular disks are evenly spaced into three areas by three connecting blocks, and the linear surrounding sleeves 32 are arranged in the three areas. The central rotating frame 31 is integrally formed. The positioning rod 33 passes through the linear surrounding sleeve 32, and the linear surrounding sleeve 32 is also rotatably arranged on the central rotating frame 31, which can limit the movement trajectory of the positioning rod 33.

[0049] The positioning rods 33 and the linear surrounding sleeves 32 are provided in three numbers and are evenly distributed on the central rotating frame 31; the positioning head 331 is a non-rotatable cylinder.

[0050] In an optional embodiment, see 10-13, the emergency post-disaster rescue auxiliary vehicle also includes an excavator arm working body 8, and the excavator arm working body 8 is also provided with an imitation brake positioning disc and a steering mechanism 7, and the imitation brake positioning disc and the steering mechanism 7 are the same structure as those used on the vehicle frame. Since the excavator arm working body 8 is relatively heavy, two worm gears 71 are provided in the steering mechanism 7, which are respectively controlled by different motors. The excavator arm working body 8 is symmetrically distributed on both sides of the carrying platform 4, and the bilateral rescue range coverage is high, the reliability is higher, and stronger post-disaster rescue performance can be achieved. The upper double mechanical arm working head can be replaced by a bucket with a claw hand, so that it can imitate the work of human hands, and the efficiency of digging to rescue trapped people is doubled.

[0051] Furthermore, the excavator arm working body 8 includes a bending arm 81 rotatably set on the fixed plate 2 of the excavator arm working body 8, the end of the bending arm 81 is rotatably connected to the middle section of the secondary opening and closing arm 82, and the end of the secondary opening and closing arm 82 is rotatably connected to the bucket 83; one end of the primary hydraulic rod 84 is rotatably set on the fixed plate 2 of the excavator arm working body 8, and the other end is rotatably set at the middle section of the bending arm 81; one end of the secondary hydraulic rod 85 is rotatably set at the front end of the secondary opening and closing arm 82, and the other end is connected to the middle section of the bending arm 81; one end of the tertiary hydraulic rod 86 is rotatably set at the front end of the secondary opening and closing arm 82, and the other end is rotatably connected to the front end of the bending member 87; the end of the bending member 87 is rotatably connected to the end of the secondary opening and closing arm 82; one end of the connecting rod 88 is rotatably connected to the middle end of the bending member 87, and the other end is rotatably connected to the bucket 83.

[0052] The specific working principle is as follows: the primary hydraulic rod 84 can control the rotation of the bending arm 81, so that the height of the secondary opening and closing arm 82 changes. The secondary hydraulic rod 85 controls the height of the end of the secondary opening and closing arm 82. The tertiary hydraulic rod 86, the connecting rod 88, and the bending member 87 together control the steering of the bucket 83, which is convenient for actual work.

The four-stage hydraulically assisted lifting workbench has a hollow work box at the top that can carry a variety of equipment.

[0054] The specific working principle is: one end of the base 91 is extended in height, and the end of the extension is connected to the first-level mechanical arm 92, which can better control the center of gravity. The first hydraulic rod 96 can control the height of the first-level mechanical arm 92. The second hydraulic rod 97 can control the height of the end of the second-level mechanical arm 93.
