It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] See also Figure 1-3 The utility model provides a technical solution: a split vehicle-mounted crane, comprising a rescue vehicle body 1 and a vehicle crane seat 7, a hydraulic telescopic arm 2 is fixedly connected to the bottom of the rear end of the rescue vehicle body 1, the rear end of the hydraulic telescopic arm 2 is rotatably connected to a connecting seat 3, the surface of the connecting seat 3 is fixedly connected to a rear supporting arm 4, and the surface of the vehicle crane seat 7 is fixedly connected to a tightening clamp 23 adapted to the rescue vehicle body 1.

[0021] A hydraulic turntable 17 is fixedly connected to the top of the vehicle hanging seat 7, a mobile tire 8 is provided at the bottom of the vehicle hanging seat 7, an output shaft of the hydraulic turntable 17 is fixedly connected to a hydraulic boom 12, a connecting frame 9 is fixedly connected to the bottom of the vehicle hanging seat 7, and a connecting piece 10 is fixedly connected to the front side and the rear side of one end face of the connecting frame 9.

[0022] The surface of the connecting member 10 is rotatably and detachably connected to the hinge seat 6 through a hinge 11, and the surface of the hinge seat 6 is fixedly connected to a traction connecting tube 5 adapted to the rear support arm 4, and the other ends of the front side and the rear side of the vehicle hanging seat 7 are vertically fixedly connected to a hydraulic telescopic rod 15.

[0023] Two traction connecting tubes 5 are sleeved on the front and rear ends of the surface of the rear supporting arm 4. The staff can rotate the connecting piece 10 and the hinge seat 6 through the hinge 11, and then fix the connecting frame 9 to the surface of the rear supporting arm 4, and then fix the rescue vehicle body 1 and the vehicle hanging seat 7 for use, thereby increasing the crane function of the rescue vehicle.

[0024] A multi-purpose and multifunctional road tow truck is realized, which can be quickly assembled and used for multiple purposes conveniently and quickly without affecting the functions of the rescue vehicle and the driving experience, thus realizing multi-purpose and multi-functionality.

[0025] The connecting piece 10 is rotatably connected to the hinge seat 6, and the connecting seat 3 is rotatably connected to the rear supporting arm 4, so that the rescue vehicle body 1 can tow the vehicle hanging seat 7 to move. After moving to the designated working position, the hydraulic telescopic arm 2 contracts, which can tighten the vehicle hanging seat 7 and the rescue vehicle body 1, thereby driving the clamping piece 23 to clamp with the rear part of the rescue vehicle body 1, thereby improving the stability of the hydraulic turntable 17 and the hydraulic boom 12 during operation, which is beneficial to the use of lifting objects.

[0026] After removing the hinge 11, the connecting piece 10 can be separated from the hinge seat 6, and then the connecting frame 9 and the vehicle hanging seat 7 can be removed from the rear part of the rescue vehicle body 1. After removing the connecting piece 10, the traction connecting tube 5 can be removed from the surface of the rear supporting arm 4, and then connected to the connecting piece 10 through the hinge 11 to avoid the loss of the traction connecting tube 5, the hinge seat 6 and the hinge 11.

[0027] An oil hydraulic control box is arranged on the rescue vehicle body 1, which can control the hydraulic actions of the hydraulic turntable 17 and the hydraulic boom 12 on the vehicle suspension seat 7. Each section of the hydraulic boom 12 is driven by a hydraulic cylinder to perform telescopic movement and other actions.

[0028] Furthermore, one end of the rear side surface at the bottom of the connecting frame 9 is vertically fixedly connected to a support rod 13 , the bottom end of the support rod 13 is fixedly connected to a base 14 , and the bottom end of the hydraulic telescopic rod 15 is fixedly connected to an anti-sliding block 16 .

[0029] In this embodiment, before lifting objects, the two hydraulic telescopic rods 15 can be extended to drive the anti-sliding block 16 to contact the ground, and the base 14 can be in contact with the ground to form a triangular support structure, thereby improving the stability of the vehicle hanging seat 7 during placement. When the vehicle hanging seat 7 is not in use, the hydraulic lifting arm 12 can be adjusted to contact the ground with the other end of the hydraulic lifting arm 12, thereby better improving the stability of the vehicle hanging seat 7 after separation.

[0030] Furthermore, a steel cable assembly 18 is fixedly connected to the bottom of the rear end of the rescue vehicle body 1 , and the other end of the rope 19 on the steel cable assembly 18 is fixedly connected to a hanging member 20 adapted to the rear supporting arm 4 .

[0031] In this embodiment, after the hydraulic telescopic arm 2 is retracted and the vehicle hanging seat 7 is tightened, the hanging part 20 is hung on the surface of the rear supporting arm 4. After the steel cable assembly 18 works, the rope 19 can be reeled in, and then the rear supporting arm 4 is tightened for the second time through the hanging part 20, thereby improving the tightness between the vehicle hanging seat 7 and the rescue vehicle body 1.

[0032] Furthermore, the other ends of the hydraulic pipelines 21 on the hydraulic turntable 17 and the hydraulic boom 12 are both provided with hydraulic oil connectors 22 adapted to the rescue vehicle body 1 .

[0033] In this embodiment, after the hydraulic oil connector 22 is connected to the hydraulic system on the rescue vehicle body 1, hydraulic power can be provided to the hydraulic turntable 17 and the hydraulic boom 12 during operation through the hydraulic pipeline 21.

[0034] Furthermore, the mobile tire 8 is a blow-up-proof tire. The advantages of the blow-up-proof tire mainly include higher safety performance, ensuring that the driver has enough time and opportunity to handle the emergency safely, avoiding dangerous tire changing situations on the highway, and facilitating rescue use.

[0035] The working principle and use process of the utility model are as follows: after the utility model is installed, the two traction connecting tubes 5 are sleeved on the front and rear ends of the surface of the rear supporting arm 4, and the staff can rotate and connect the connecting piece 10 with the hinge seat 6 through the hinge 11, and then fix the connecting frame 9 to the surface of the rear supporting arm 4, and then fix and install the rescue vehicle body 1 and the vehicle hanging seat 7 for use, increase the crane function of the rescue vehicle, and realize a multi-purpose and multi-functional road tow truck, and rotate and connect the connecting piece 10 with the hinge seat 6, and rotate and connect the connecting seat 3 with the rear supporting arm 4, so that the rescue vehicle body 1 can tow the vehicle hanging seat 7 to move, and after moving to the designated working position, the hydraulic telescopic arm 2 shrinks, and the vehicle hanging seat 7 and the rescue vehicle body 1 are tightened, thereby driving the clamping piece 23 to clamp the rear part of the rescue vehicle body 1, and then driving the clamping piece 23 to clamp the rear part of the rescue vehicle body 1, thereby improving the stability of the hydraulic turntable 17 and the hydraulic boom 12 during the working process, which is beneficial to the use of lifting objects.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
