Description

Technical Field

[0001] The utility model relates to the technical field of road tow trucks, in particular to a road tow truck. Background Art

[0002] Rural roads generally refer to roads connecting townships and administrative villages. On rural roads, due to the lack of supervisors and lax management, various tricycles, motorcycles, cars and other vehicles are often parked directly on the road, affecting the smooth flow of the road. When the owner of the car is nearby, the road traffic management personnel will often persuade the owner to drive away, and when the owner is not nearby, a road tow truck is usually used to tow the obstructing vehicle away.

[0003] The publication number authorized by China is CN211308362U, and the patent is named a multifunctional road tow truck. The device includes a vehicle head, which is arranged on the front end top surface of the frame plate, and several groups of wheels are symmetrically and in the same direction. The frame plate pulleys are provided with several groups, and the several groups of frame plate pulleys are divided into two rows and arranged on the frame plate. The consignment device is arranged on the top surface of the frame plate. The utility model is advantageous in improving the setting of the road tow truck, changing the lifting platform and the vehicle-mounted lifting flatbed tow truck adopted by the traditional road tow truck, and improving it to a current setting that can have consignment and single-head landing. The application of this equipment is more extensive, and the hydraulic rod on the front side can lift and move the trailer plate back and forth, so that the consignment plate is more widely used. For this reason, a group of micro-rotation structures of the hydraulic structure are added at the bottom end of the hydraulic structure, so that the hydraulic rod can rotate slightly to achieve a suitable towing effect, which is suitable for popularization and use.

[0004] Although the above device can make the use of the pallet more extensive, there are still some problems when using the device:

[0005] 1. The device does not have an auxiliary pulling mechanism. When the device is used to clear an obstacle vehicle, it is difficult to load the obstacle vehicle.

[0006] 2. The device does not have an extension mechanism, and the bottom plate of the transport device cannot be extended. Therefore, the slope angle formed by its plate structure and the ground is large, which is not conducive to loading.

[0007] In view of the above situation, technical innovation is carried out on the basis of the existing road tow trucks. Utility Model Content

[0008] The purpose of the utility model is to provide a road tow truck to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a road tow truck, comprising a bearing plate and an electric slide rail, a front baffle being fixed at one end of the bearing plate, and a winch being fixed at the top of the front baffle, a reduction motor being fixed at the front end of the winch, a pulley being fixed at one side of the front baffle, and a steel cable being arranged at the outer side of the pulley, a limiting sleeve being fixed at one side of the top of the bearing plate, and a contact switch being fixed at one side of the limiting sleeve, a positioning block being fixed at the outside of the steel cable, and a hook being fixed at the end of the steel cable, the electric slide rail being fixed to the bottom end of the bearing plate, and a support plate being arranged at the bottom end of the electric slide rail, a rotating connecting piece being arranged at one side of the support plate, and a vehicle body being connected at the bottom end of the rotating connecting piece.

[0011] Furthermore, a tail plate is provided on the inner side of one end of the supporting plate away from the front baffle, and the tail plate is rotatably connected to the supporting plate.

[0012] Furthermore, a fixing ear is provided at the bottom end of one side of the tail plate, and the fixing ear is made of high-speed steel.

[0013] Furthermore, a limiting block is provided at the bottom of one end of the carrying plate away from the front baffle, and the limiting block is fixed to the carrying plate in an integral manner.

[0014] Furthermore, a fixing component is arranged on a side of the top of the bearing plate away from the limiting sleeve, and the fixing component comprises a second fixing ear and a fixing pin, and a fixing pin is arranged inside the second fixing ear.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the device is provided with an auxiliary trailer mechanism, which can more conveniently load road-obstructed vehicles onto the device, which is beneficial to improving the practicality of the device; at the same time, the device is provided with a retractable rear ramp plate structure, which can extend the ramp when lowered, thereby reducing the slope of the ramp, facilitating loading, and helping to improve the convenience of the device.

[0016] 1. The utility model is provided with a winch, a reduction motor, a pulley, a steel cable, a limit sleeve, a contact switch, a positioning block and a hook. The steel cable is fixedly wound on the outside of the winch. When the user uses the device to load a vehicle, the hook can be pulled to extract the steel cable, and the hook can be hung on a firm and suitable force application point such as a vehicle beam, and then the reduction motor can be turned on. At this time, the reduction motor drives the winch to retract the steel cable, thereby pulling the vehicle through the steel cable to assist the user in loading the vehicle on the device. The steel cable passes through the limit sleeve, and the contact switch is electrically connected to the reduction motor. The limit sleeve can limit the force application direction of the steel cable. When the steel cable is about to be fully retracted, the positioning block contacts the contact switch outside the limit sleeve, and the contact switch cuts off the power to the reduction motor to prevent the vehicle from being excessively pulled and colliding with the front fender or other structures. Through the above structure, the device can more conveniently load road-obstructed vehicles on the device, which is conducive to improving the practicality of the device.

[0017] 2. The utility model arranges the tail board, the first fixing ear, the limit block, the fixing assembly, the second fixing ear and the fixing pin, so that the tail board is rotatably connected to the load-bearing plate. Before the user loads the vehicle onto the device, the fixing pin can be pulled out, and the tail board can be rotated at this time. When the tail board is rotated to the same angle as the load-bearing plate, the limit block can limit the rotation of the tail board, thereby extending the length of the load-bearing plate, making it easier for the load-bearing plate to form a smaller slope with the ground. When the vehicle is loaded onto the device, the user can lift the tail board so that the holes of the first fixing ear and the second fixing ear are aligned, and fix the load-bearing plate by the fixing pin to prevent it from falling during driving. Through the above structure, the device can extend the ramp, thereby reducing the slope of the ramp, making it easier to load the vehicle, which is conducive to improving the convenience of the device.

The limit sleeve 7 can limit the force direction of the steel cable 6. When the steel cable 6 is about to be retracted, the positioning block 9 contacts the contact switch 8 outside the limit sleeve 7, and the contact switch 8 cuts off the power of the reduction motor 4 to prevent the vehicle from being pulled excessively and colliding with the front baffle 2 or other structures. The tail plate 16 is rotatably connected to the load-bearing plate 1. Before the user loads the vehicle onto the device, the fixing pin 1902 can be pulled out. The tail plate 16 can rotate. When the tail plate 16 rotates to the same angle as the supporting plate 1, the limit block 18 can limit the rotation of the tail plate 16, thereby extending the length of the supporting plate 1, making it easier for the supporting plate 1 to form a smaller slope with the ground.
