Description

Technical Field

[0001] The utility model relates to the technical field of tow trucks, in particular to a double-layer full-ground flatbed tow truck. Background Art

[0002] With the rapid development of road traffic and the dramatic increase in the number of cars, the number of traffic accidents is also increasing, so the role of road tow trucks is becoming more and more prominent. As a type of road tow truck, a flatbed tow truck has its own special function: the flatbed tow truck can place the rear part of its flatbed on the ground, turning the rear part of the flatbed into a bridge connecting the ground and the front part of the flatbed, making it easy to move the accident vehicle onto the flatbed of the flatbed tow truck and transport it away from the accident scene, thereby achieving the purpose of towing. Due to structural limitations, the inclined bridge formed by the rear half of the flatbed of the more common flatbed tow trucks currently forms a large angle with the ground. Many vehicles now have relatively low chassis and very small approach angles. If this type of flatbed road tow truck is used for towing or transportation, it is easy to cause damage to the towed vehicle in the process of moving the accident vehicle onto the tow truck flatbed.

[0003] Chinese patent authorization announcement number CN 201317307Y, with an authorization announcement date of September 30, 2009, discloses a flatbed telescopic and flipping control mechanism for a ground-type flatbed road tow truck, comprising a frame and a flatbed, which is slidably arranged on the frame. The flatbed is in the shape of an "I" (Chinese character for "工"), with a vertical frame provided at the front, a telescopic control rod provided at the bottom of the flatbed, a hydraulic cylinder provided in the telescopic control rod, a rear end of the telescopic control rod being hinged to the rear of the frame, a front portion of the telescopic control rod being in the shape of an "I" (Chinese character for "工"), an upper end of the rod being hinged to the upper end of the vertical frame of the flatbed, a flatbed lifting cylinder provided between the telescopic control rod and the frame, one end of the flatbed lifting cylinder being hinged to the front of the frame and the other end being hinged to the rear of the telescopic control rod.

[0004] This device controls the entire flatbed to be placed on the ground, essentially eliminating the angle between the flatbed and the ground, allowing various vehicles to be easily moved onto the flatbed. However, this type of tow truck can only tow two vehicles at most. If a large number of vehicles need to be towed, it may require a long wait or the need to mobilize more tow trucks. Too many tow trucks themselves may also cause traffic congestion. Summary of the Invention

[0005] The purpose of the utility model is to overcome the defects and shortcomings of the existing technology and provide a double-layer full-ground flatbed tow truck with a simple structure, convenient loading and unloading, and a large carrying capacity.

[0006] In order to achieve the above object, the technical scheme of the utility model is: a double-layer full-floor flat plate wrecker truck, including automobile chassis and flat plate, the flat plate is slidably connected on the automobile chassis, the front end of the flat plate is provided with a stand, the lower portion of the flat plate is provided with a telescopic control rod, the telescopic control rod connects the automobile chassis and the flat plate together, the automobile chassis is provided with a flat plate lifting oil cylinder, the flat plate lifting oil cylinder pushes the flat plate to the ground through the telescopic control rod, characterized in that: the flat plate comprises an upper layer of vehicle loading plate, a lower layer of vehicle loading plate and a jacking oil cylinder hinged between the upper layer of vehicle loading plate and the lower layer of vehicle loading plate.

[0007] The telescopic control rod is internally provided with a hydraulic oil cylinder, the rear end of the telescopic control rod is hinged with the rear portion of the vehicle frame, and the front portion of the telescopic control rod is in "L" shape, and the upper end thereof is hinged with the upper end of the stand.

[0008] The tail end of the lower layer of vehicle loading plate is internally provided with a telescopic tail plate.

[0009] The automobile chassis is provided with an upper-mounted inclined plate moving wheel at the tail end.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. The utility model changes the single-layer flat plate into the double-layer flat plate, and compared with the general flat plate road wrecker truck, one more vehicle can be transported, and the transportation efficiency is higher; the telescopic tail plate in the lower layer of vehicle loading plate can facilitate the vehicle to be placed on the flat plate and also enable the flat plate to be placed on the ground at a smaller inclination angle.

[0012] 2. The utility model controls the front and back translation of the flat plate through the telescopic control rod, controls the rotation of the flat plate through the flat plate lifting oil cylinder, and controls the whole flat plate to be placed on the ground through the hinge between the flat plate and the upper end of the front portion of the telescopic control rod, basically eliminates the included angle between the flat plate and the ground, so that various vehicles can be very conveniently moved to the flat plate, and the design is reasonable and ingenious, the wrecker is convenient, and the application range is wide.

[0013] 3. The utility model is provided with the upper-mounted inclined plate moving wheel at the tail end of the automobile chassis, so that the flat plate is more smooth during the inclination and landing process. DRAWINGS

[0016] In the drawing: automobile chassis 1, flat plate 2, stand 3, telescopic control rod 4, flat plate lifting oil cylinder 5, upper layer of vehicle loading plate 6, lower layer of vehicle loading plate 7, jacking oil cylinder 8, telescopic tail plate 9, upper-mounted inclined plate moving wheel 10. DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] See also Figures 1-2 A double-layer fully grounded flatbed tow truck comprises a car chassis 1 and a flatbed 2. The rear end of the car chassis 1 is equipped with an upper inclined plate moving wheel 10. The flatbed 2 is slidably connected to the car chassis 1. The front end of the flatbed 2 is provided with a vertical frame 3. A telescopic control rod 4 is installed under the flatbed 2. A hydraulic cylinder is provided in the telescopic control rod 4. The rear end of the telescopic control rod 4 is hinged to the rear of the car chassis 1. The front part of the telescopic control rod 4 is "L"-shaped, and its upper end is hinged to the upper end of the vertical frame 3. A flatbed lifting cylinder 5 is provided on the car chassis 1, and the flatbed lifting cylinder 5 pushes the flatbed 2 to the ground through the telescopic control rod 4. The flatbed 2 comprises an upper loading plate 6, a lower loading plate 7 and a lifting cylinder 8 hinged therebetween. A telescopic tail plate 9 is installed inside the tail end of the lower loading plate 7.

[0019] When a vehicle needs to be transported, the telescopic tail plate 9 at the rear of the lower loading plate 7 is extended, and the flatbed 2 is moved horizontally to the rear of the tow truck under the control of the telescopic control rod 4. When the flatbed 2 is moved horizontally to the specified position, the flatbed lifting cylinder 5 starts to work. The flatbed lifting cylinder 5 controls the front end of the flatbed 2 to move along an arc trajectory through the telescopic control rod 4. The telescopic tail plate 9 at the rear end of the flatbed 2 touches the ground and moves backward along the ground. Finally, the front end of the flatbed 2 gradually approaches the ground until the support feet on the left and right sides of the lower front end of the flatbed 2 touch the ground. At this time, the flatbed 2 is basically completely placed on the ground. Then the accident vehicle is moved to the lower loading plate 7 of the flatbed 2 and the vehicle is fixed. When there are more than two vehicles, the vehicle can be parked on the upper loading plate 6 first, and the upper loading plate 6 is raised by the lifting cylinder 8, and then the vehicle is parked on the lower loading plate 7. After the vehicle is parked properly, the reverse operation is performed to move the flatbed 2 back to the initial position. After that, the tow truck leaves the tow truck site and completes the tow truck work.
