DETAILED DESCRIPTION
[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.
[0019] like Figure 1-3 A tow truck for wheel positioning shown in the figure comprises a trailer body 1, a traction winch 2 is arranged at the front end of the trailer body 1, a faulty vehicle is towed by the traction winch 2, so that the vehicle can be moved onto the trailer body 1, and two parallel positioning mechanisms 3 are arranged in the middle of the front end of the trailer body 1, and the two positioning mechanisms 3 are arranged in left and right directions;
[0020] The positioning mechanism 3 includes two through slots 31 provided on the trailer body 1 and a mounting seat 32 fixed on the bottom surface of the trailer body 1. The two through slots 31 are arranged in the front-to-back direction. A rotating shaft 33 is rotatably mounted on the lower end of the mounting seat 32. Both ends of the rotating shaft 33 are fixed with a transverse plate 34. Both ends of the two transverse plates 34 are fixed with mounting frames 35. A front positioning roller 36 and a rear positioning roller 37 are respectively mounted on the two mounting frames 35. The rotating shaft 33 is fixed to the transverse plate 34 at a position biased in front of the positioning roller 36, so that the center of gravity is located at one end of the rear positioning roller 37. The rotating shaft 33 is rotatably connected to the mounting seat 32 through a bearing, so that when the positioning mechanism 3 is in a natural state, the height of the rear positioning roller 37 is lower than the height of the front positioning roller 36.
[0021] When the positioning mechanism 3 is in a natural state, the front positioning roller 36 is exposed from the upper end of the through slot 31, and the rear positioning roller 37 is located at the lower end of the slot 41, so that when the faulty vehicle moves, it first contacts the front positioning roller 36, thereby pushing the positioning mechanism 3 to rotate, so that the rear positioning roller 37 limits the rear end of the wheel;
[0022] A slide groove 38 is provided on the inner wall of the two horizontal plates 34, and a limit beam 39 is slidably installed between the two slide grooves 38. A spring 381 is provided on the side of the limit beam 39 away from the rear positioning roller 37, and a fixed tooth 391 is provided on the other side of the limit beam 39. A guide rod is fixed between the two ends of the slide groove 38, and the spring 381 is sleeved on the guide rod. A slider is penetrated on the guide rod, and the slider is slidably matched with the guide rod and the slide groove 38, and the end of the limit beam 39 is rotatably connected with the slider;
[0023] Furthermore, a fixing seat 40 is provided between the limiting beam 39 and the rear positioning roller 37. The fixing seat 40 is installed on the bottom surface of the trailer body 1, and a slot 41 is provided on the side of the fixing seat 40 close to the limiting beam 39. A plurality of movable teeth 42 are rotatably installed in the slot 41. The plurality of movable teeth 42 are linearly arranged, and the inner ends of all the movable teeth 42 are rotatably installed on a connecting rod 43. A hydraulic cylinder 44 is rotatably installed on the inner side of the slot 41, and the telescopic end of the hydraulic cylinder 44 is rotatably connected to the connecting rod 43.
[0024] The movable teeth 42 are in the shape of a diamond, and the hydraulic cylinder 44 pushes the movable teeth 42 to rotate at an angle of 30°. After the movable teeth 42 are rotated, the limiting beam 39 can slide downward on the fixed seat 40 when the rear positioning roller 37 is pushed. The fixed teeth 391 are adapted to the tooth grooves formed between two adjacent movable teeth 42, and the width of the fixed teeth 391 is greater than the width of the slot 41. Through the cooperation between the fixed teeth 391 and the movable teeth 42, the positioning mechanism 3 is limited after rotation to avoid rotation.
[0025] In this embodiment, the faulty vehicle is towed by the traction winch 2. When the faulty vehicle moves to the positioning mechanism 3, the front wheel of the faulty vehicle pushes the front positioning roller 36, causing the rotating shaft 33 to rotate, driving the rear positioning roller 37 to expose the through groove 31 until the rear positioning roller 37 contacts the wheel. While the rotating shaft 33 rotates, the cross plate 34 and the limiting beam 39 rotate at the same time, and the limiting beam 39 is squeezed by the fixed seat 40 to push it to move in the opposite direction to the front positioning roller 36, and the fixed teeth 391 are kept in engagement with the movable teeth 42 by the spring 381. The cooperation between the fixed teeth 391 and the movable teeth 42 prevents the rotating shaft 33 from rotating, so that the front positioning roller 36 and the rear positioning roller 37 automatically limit the front and rear directions of the wheel to prevent the faulty vehicle from rolling back. Compared with the current method of fixing the wheel by ropes, this method greatly reduces the time required for wheel positioning.
[0026] When the faulty vehicle needs to be moved out, all the movable teeth 42 are pushed to rotate by the hydraulic cylinder 44, so that the fixed teeth 391 can slide downward on the fixed seat 40, so that when the rear positioning roller 37 is squeezed, the rear positioning roller 37 can rotate downward to make the wheel disengage from the positioning mechanism 3.
[0027] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.
[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
