Description

Technical Field

[0001] This utility model relates to the field of control device technology, specifically to a crank-type lead screw moving device. Background Technology

[0002] When a car breaks down, the wheels may lock up and not rotate properly, requiring a tow truck to transport the vehicle to another location. However, existing car movers on the market either have swivel wheels or lever-type wheels. Swivel wheels can cause the winch on the trailer to swerve when pulling the vehicle being rescued, which may cause damage to the vehicle. Lever-type wheels require workers to use a crowbar to turn them, which is risky both when raising and lowering them. Moreover, both types are very heavy, making it difficult for one person to move two car movers at once, which greatly reduces rescue efficiency. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide a crank-type lead screw moving device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-4 As shown, this utility model provides a crank-type lead screw vehicle mover. The vehicle mover includes a main frame 1, a lead screw assembly 2, a connecting assembly 3, and a lifting assembly 4. By setting the lead screw assembly 2, the connecting assembly 3, and the lifting assembly 4, the rotational motion of the lead screw assembly 2 is converted into linear motion. Through the connecting assembly 3, the linear motion of the lead screw assembly 2 is converted into the rotational motion of the lifting assembly 4, thereby lifting the wheels of the faulty vehicle. The lead screw assembly 2 includes a sleeve 21, which is fixedly installed on one side of the middle of the main frame 1. Several reinforcing plates 211 are fixedly installed between the sleeve 21 and the main frame 1. By setting the reinforcing plates 211, the stability of the sleeve 21 can be improved. A lead screw 22 is rotatably installed inside the sleeve 21. A hexagonal seat 23 is fixedly installed at one end of the lead screw 22. By setting the hexagonal seat 23, when the electric wrench is placed on the hexagonal seat 23, the lead screw 22 can be driven to rotate by the electric wrench. A threaded sleeve 24 is slidably installed inside the sleeve 21. The lead screw 22 passes through the threaded sleeve 24 and is threadedly rotatably connected to the threaded sleeve 24. By rotating the lead screw 22, the lead screw 22 can drive the threaded sleeve 24 to move vertically up and down inside the sleeve 21. The connecting component 3 includes a connecting rod 31, and two connecting rods 31 are provided. One end of the connecting rod 31 is fixedly provided with a first hinge seat 32, and the connecting rod 31 is hinged to the outer wall of the threaded sleeve 24 through the first hinge seat 32. The other end of the connecting rod 31 is fixedly provided with a second hinge seat 33, and a crank 34 is hingedly installed on the second hinge seat 33. When the threaded sleeve 24 moves vertically, the threaded sleeve 24 can make the crank 34 move through the first hinge seat 32, the connecting rod 31 and the second hinge seat 33. The lifting assembly 4 includes two rotating shafts 41, which are symmetrically mounted on the ends of the main frame 1. One end of a crank 34 is fixedly connected to one end of each rotating shaft 41. When the crank 34 moves, it causes the rotating shafts 41 to rotate. Each end of the rotating shaft 41 is fixedly mounted with a mounting bracket 42. A rotating shaft 43 is rotatably mounted between adjacent mounting brackets 42. A nylon roller 44 is fixedly mounted on each rotating shaft 43. The rotating shaft 41 can be connected to the nylon roller 44 via the mounting brackets 42. The cylinder 44 rotates around the axis of the rotating shaft 41. A patterned steel support plate 46 is fixedly installed on one side of each of the two adjacent fixed frames 42. The patterned steel support plate 46 can rotate synchronously with the nylon roller 44. When the patterned steel support plate 46 rotates upward, the wheel can be lifted. A first reinforcing frame 45 and a second reinforcing frame 451 are fixedly installed on the lower surface of the patterned steel support plate 46. By setting the first reinforcing frame 45 and the second reinforcing frame 451, the overall strength of the patterned steel support plate 46 can be improved and deformation can be avoided.

[0018] Both ends of the main frame 1 are provided with insertion holes 47, and both ends of the main frame 1 are provided with movable limit pins 48. The limit pins 48 pass through the insertion holes 47 and are interference-fitted with the inner wall of the insertion holes 47. One end of the limit pins 48 is in movable contact with one side of the fixed frame 42. By setting the insertion holes 47 and the limit pins 48, if the self-locking effect of the lead screw 22 fails, the limit pins 48 are inserted into the insertion holes 47, which can limit the fixed frame 42, the nylon roller 44 and the patterned steel support plate 46, and prevent the fixed frame 42, the nylon roller 44 and the patterned steel support plate 46 from reversing and resetting. This can ensure that the car mover can be used normally and will not cause damage to the car.

[0019] Working principle: When using this vehicle mover for vehicle rescue, the staff first positions the tow truck facing the vehicle to be rescued, then removes the vehicle mover from the tow truck and places it under the wheels of the vehicle that cannot turn normally, ensuring that the vehicle mover will not scratch or bump the vehicle. Then, the electric wrench is placed on the hexagonal seat 23, and the electric wrench is used to turn the screw 22. The screw 22 causes the threaded sleeve 24 to rise vertically. The threaded sleeve 24 causes the rotating shaft 41 to rotate through the two first hinge seats 32, the connecting rod 31, the second hinge seat 33, and the crank 34. The rotating shaft 41 causes the nylon roller 44 and the patterned steel support plate 46 to rotate through the fixed frame 42. At this time, the two patterned steel support plates 46 are in an upward flipped state, i.e., an upward state, which lifts the wheels. When the lead screw 22 causes the threaded sleeve 24 to descend vertically, the nylon roller 44 and the patterned steel support plate 46 rotate in opposite directions to achieve the descent of the patterned steel support plate 46, which in turn causes the wheel to descend and fall. Meanwhile, after the wheels are lifted, by inserting two limiting pins 48 into the corresponding holes 47, the limiting pins 48 limit the fixing frame 42, nylon roller 44 and patterned steel support plate 46, preventing the fixing frame 42, nylon roller 44 and patterned steel support plate 46 from flipping back to reset, which can ensure that the car mover can be used normally and will not cause damage to the car. After all the wheels that cannot turn properly have been lifted by the vehicle movers, the vehicle to be rescued is pulled onto the trailer using the winch on the trailer, and then all the vehicle movers are removed, thus completing the vehicle rescue operation.

[0020] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0021] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
