Specific embodiments

[0024] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0026] Adjusting mechanism 15 includes first bevel gear 16 and second bevel gear 17, and one first bevel gear 16 is rotatably connected to the center top of hollow slot 2, and two mutually symmetrical second bevel gears 17 are rotatably connected on the both sides of hollow slot 2, and the two second bevel gears 17 are engaged with first bevel gear 16.

[0027] The disposal mechanism 5 comprises an arc-shaped rotating block 7 and an inverted L-shaped block 8, the arc-shaped rotating block 7 is rotatably connected with the arc-shaped slot 6 through a rotating shaft, and the inverted L-shaped block 8 is fixedly connected with the side wall of the arc-shaped rotating block 7. After the drive shaft of the fault vehicle is broken, there is a great possibility of bottoming out, and after the broken drive shaft contacts the ground, it will affect the towing of the wrecker, and even cause secondary accidents. When the wrecker comes to rescue, the first consideration is to temporarily lift and connect the broken drive shaft, connect the disposal device with the vehicle frame through the disposal mechanism 5, so that the disposal device is fixed with the vehicle frame, and then the broken drive shaft is lapped on one side of the multi-section support 13, and the other section of the drive shaft is also lapped on the other side of the multi-section support 13. The multi-section support 13 temporarily supports the broken drive shaft to prevent the drive shaft from bottoming out. The adjusting mechanism 15 can adjust the distance between the two disposal mechanisms 5, so as to facilitate the placement of the disposal device between the vehicle frames during rescue, and then the two disposal mechanisms 5 are pushed to the two sides of the vehicle frame through the adjusting mechanism 15 to realize fixation. Similarly, when facing different specifications of the vehicle frame, the distance between the adjusting mechanism 15 can also be adjusted, so that the disposal device can be suitable for various fault vehicles, and the adaptability and convenience of the disposal device are improved.

[0028] As a technical optimization scheme of the utility model, the multi-section support 13 is symmetrical on both sides, and each section of the multi-section support 13 is rotatably connected, and the inner wall of the multi-section support 13 is uniformly provided with rotatably connected rollers 14. Generally, the drive shaft is a cylindrical structure, but the size is different, so the rotatable multi-section support 13 is used to support the drive shaft, so that drive shafts of different diameters can be effectively supported by the multi-section support 13, and the rollers 14 directly abut against the drive shaft, which can effectively reduce friction and reduce damage to the multi-section support 13, thereby prolonging the service life of the multi-section support 13.

[0029] As a technical optimization scheme of the utility model, the fixed block 1 is fixedly connected with the reinforcing ribs 12 on both sides of the bottom end, and the two reinforcing ribs 12 are fixedly connected with the top of the stand 11 on both sides. The reinforcing ribs 12 can improve the overall strength of the disposal device.

[0030] As a technical optimization scheme of the utility model, the L-shaped block 8 is rotationally connected with a flap 9 at the bottom, two bolt holes 91 are symmetrically formed on the two sides of the flap 9, two connecting bolts 10 are movably connected with the top of the L-shaped block 8 through bolts, and the connecting bolts 10 are matched with the bolt holes 91. The sidewall of the L-shaped block 8 directly abuts against the sidewall of the frame, and the top of the L-shaped block 8 abuts against the top of the frame, so that the two L-shaped blocks 8 are fixed on the frame to form stable fixation, and the frame of part of the vehicle is not rectangular, in an inclined state, at this time, under the rotating action of the arc-shaped rotating block 7, when the adjusting mechanism 15 pushes the L-shaped block 8 to abut against the frame, the L-shaped block 8 can rotate and abut against the inclined sidewall of the frame, and the stability of the disposal device can be ensured, and after the disposal device is fixed, the flap 9 can be turned to be horizontal and connected through the connecting bolt 10, so that the stability and safety of the disposal device are further improved.

[0031] As a technical optimization scheme of the utility model, the sidewall of the second bevel gear 17 is fixedly connected with a round rod, the end of the round rod is fixedly connected with a screw rod 18, and the screw rod 18 is threadedly connected with the sliding block 3 and the connecting column 4. The adjusting mechanism 15 drives the two second bevel gears 17 to synchronously rotate through the rotation of the first bevel gear 16, so that the screw rod 18 rotates and synchronously drives the two sliding blocks 3 and the connecting column 4 to synchronously approach or move away, that is, the two disposal mechanisms 5 can be pushed to approach or move away from each other, so that the disposal device can be conveniently installed on the frame.

[0032] As a technical optimization scheme of the utility model, the top end of the first bevel gear 16 is fixedly connected with a connecting rod penetrating through the fixed block 1, and the top end of the connecting rod is fixedly connected with a handle 19. The handle 19 can be rotated to drive the first bevel gear 16 to rotate, so that the operation is convenient and the position of the L-shaped block 8 can be conveniently observed.

[0033] As a technical optimization scheme of the utility model, the end of the connecting column 4 is in an arc-shaped structure, and the end of the connecting column 4 does not affect the rotation of the L-shaped block 8. The connecting column 4 is rotationally connected with the L-shaped block 8 and does not interfere with each other, so that the angle change of the L-shaped block 8 can be realized.

[0034] When the present invention is in use, the tow truck personnel arrive at the scene, observe the position of the broken transmission shaft, and after determining the position, take the disposal device to the bottom of the vehicle frame, turn the handle 19 to drive the first bevel gear 16 to rotate, and the rotation of the first bevel gear 16 drives the two second bevel gears 17 to rotate synchronously, so that the screw 18 rotates and synchronously drives the two sliding blocks 3 and the connecting column 4 to move away from each other, thereby pushing the two inverted L-shaped blocks 8 away from each other. During the rotation of the handle 19, the tow truck personnel observe the positions of the two inverted L-shaped blocks 8 at any time and adjust the center of the disposal device to correspond to the broken position of the transmission shaft until the side walls of the two inverted L-shaped blocks 8 directly abut against the side walls of the frame and the tops of the inverted L-shaped blocks 8 abut against the tops of the frame, so that the two inverted L-shaped blocks 8 are fixed on the frame to form a stable fixation. If the frame is tilted, the arc-shaped rotating block 7 Under the action of rotation, when the adjustment mechanism 15 pushes the inverted L-shaped block 8 to abut against the frame, the inverted L-shaped block 8 can rotate and abut against the inclined side wall of the frame, which can also ensure the stability of the handling device. When the handling device is fixed, the flap 9 can be flipped to the horizontal and connected through the connecting bolt 10. At this time, the broken section of the drive shaft is overlapped on one side of the multi-section bracket 13, and the other section of the drive shaft is also overlapped on the other side of the multi-section bracket 13. The broken drive shaft is temporarily supported by the support of the multi-section bracket 13, wherein the roller 14 directly abuts against the drive shaft, which can effectively reduce friction. Since the two ends of the broken drive shaft are still connected to the vehicle body, a stable connection state can be formed between the drive shaft, the multi-section bracket 13, the inverted L-shaped block 8 and the frame, and it can be towed by a tow truck without worrying about the drive shaft bottoming out.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
