The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

As shown in fig. 1, an embodiment of the present invention provides a lifting vehicle 100, which is applied to manufacturing of vehicles such as motorcycles and the like, and can assist a worker in lifting or lowering a motorcycle, so as to reduce labor intensity and improve work efficiency.

Illustratively, the lift truck 100 includes: a car body 10 and a hoisting mechanism 20. The hoisting mechanism 20 is disposed on the vehicle body 10. The cart body 10 may be a hand cart or an automatic cart. For example, in the present embodiment, the cart body 10 is designed as a hand cart, and has a simple structure, low manufacturing and using costs, and convenient and fast use. The hand trolley consists of a frame and two groups of roller pairs, and is stable and reliable in movement.

With continued reference to fig. 2, the hoist mechanism 20 includes: a support 21, a support bracket 22 and a support pallet 23. The supporting frame 22 is arranged on the support 21, and the supporting frame 22 comprises a mounting body 221 which extends vertically; the supporting plate 23 is disposed on the mounting body 221, and the supporting plate 23 is located above the support 21.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the hoisting mechanism 20 of the above scheme is applied to a hoisting vehicle 100, and is particularly used in occasions where lifting and falling of motorcycles are needed during manufacturing, maintenance or maintenance of vehicles such as motorcycles. When the support bracket 23 is used, the support bracket 23 is arranged on the installation body 221 of the support frame 22, then the support frame 22 and the support seat 21 are assembled and fixed, and the support bracket 23 is positioned above the support seat 21, so that the support bracket 23 is small in transverse length extending out of the support seat 21, small in occupied transverse space and well suitable for a vehicle model with a small gap between a support silencer and a rear cradle; and the cantilever length of the supporting plate 23 under the mounting structure is greatly shortened, so that the requirement on structural strength is low, the failure risk of deformation and fracture when the supporting plate 23 supports a vehicle with larger weight is small, and the working reliability and stability of the lifting mechanism 20 when the motorcycle is lifted and placed are improved.

It can be understood that, when the lifting mechanism 20 is used, the supporting support plate 23 needs to be inserted into a gap between the muffler and the rear cradle to form a clamping effect, so as to ensure the stability of the support of the motorcycle and prevent the motorcycle from being inclined and falling in the lifting process.

With continued reference to fig. 2, in order to avoid the supporting plate 23 from crushing the rear cradle due to the excessive hard contact force, in some embodiments, the hoisting mechanism 20 further includes a soft sleeve 24, and the soft sleeve 24 is sleeved on the supporting plate 23. The soft sleeve 24 can be separated and blocked between the support supporting plate 23 and the muffler and the rear cradle, so that the deformation and damage caused by excessive rigid extrusion are avoided. Alternatively, the soft cover 24 may be made of any one of polyurethane, rubber, resin, silicone, and the like. For example, the soft cover 24 in this embodiment is made of polyurethane with good wear resistance.

Referring to fig. 2, in some embodiments, the hoisting mechanism 20 further includes a first fastening member 25, the mounting body 221 is provided with a first through hole, and the first fastening member 25 is disposed through the first through hole and abuts against the supporting plate 23. The first fastening member 25 can couple and fix the support plate 23 to the mounting body 221, provide sufficient structural strength to the support plate 23, and allow the support plate 23 to rotate flexibly.

For example, the first fastening member 25 is a T-shaped shaft, a through hole is formed in a side of the mounting body 221 facing away from the support supporting plate 23, the T-shaped shaft penetrates through the first through hole and then penetrates into the through hole of the support supporting plate 23, the T-shaped shaft end and the support supporting plate 23 are directly and firmly welded, the support supporting plate 23 can be flexibly rotated, the mounting manner and the structure are simple, and the connection reliability is high.

With reference to fig. 2, in addition, on the basis of the above embodiment, the supporting frame 22 further includes a connecting body 222, the connecting body 222 is connected with the mounting body 221 and extends along the transverse direction, and the connecting body 222 is connected and fixed with the support 21. The support 22 can be integrally assembled and fixed with the support 21 by connecting the connector 222 with the support 21. The connecting body 222 and the mounting body 221 may be an integral structure or may be detachably assembled. The present embodiment preferably employs an integral structure. The connecting body 222 and the mounting body 221 are specifically L-shaped or U-shaped. At this time, an inner concave cavity can be formed between the connecting body 222 and the mounting body 221, and the inner concave cavity can accommodate the supporting pallet 23, so that the supporting pallet 23 can be mounted above the support 21, and the purpose of reducing the length of the cantilever is achieved.

In some embodiments, the support 21 includes a vertical column 211, the vertical column 211 is provided with a second through hole, and the connecting body 222 is inserted into the second through hole for fixing.

Preferably, the connecting body 222 and the second through hole are configured to have a non-circular (preferably rectangular) cross-section in order to prevent the assembled support frame 22 from rotating when subjected to a deflection load of the motorcycle, thereby making the motorcycle unstable in lifting.

Referring to fig. 2, in some embodiments, the support 21 further includes a second fastening member 212, the upright 211 further defines a third through hole communicated with the second through hole, and the second fastening member 212 is disposed in the third through hole and abuts against the connecting body 222. The second fastener 212 may thus couple the connector 222 to the upright 211 and provide sufficient structural strength to support the plate 23.

For example, the second fastening member 212 is a bolt, a threaded hole is formed in a side surface of the connecting body 222 facing the second through hole, the bolt can be directly screwed into the threaded hole after passing through the second through hole, the mounting manner and the structure are simple, and the connection reliability is high. Further, in order to improve the connection strength between the connection body 222 and the upright post 211, two or more bolts may be provided at the same time, specifically selected according to actual needs.

With reference to fig. 2, in order to realize the lifting function of the lifting mechanism 20, in some embodiments, the support 21 further includes a lifting sleeve 213 and a lifting screw 214, the upright post 211 is slidably inserted into the lifting sleeve 213, an inner cylindrical wall of the lifting sleeve 213 is provided with an internal thread structure, the lifting screw 214 is screwed with the internal thread structure and is movably mounted on the lifting sleeve 213, and an end of the lifting screw 214 abuts against the upright post 211. When the motorcycle needs to be lifted, the lifting screw 214 is screwed clockwise, and the lifting screw 214 can push the upright post 211 to ascend in the lifting sleeve 213, so that the support pallet 23 is driven to lift the motorcycle. On the contrary, when the lifting screw 214 is screwed reversely, the motorcycle can be driven to descend, and the lifting screw 214 is used as a power source, so that the height of the supporting support plate 23 can be steplessly adjusted, and the requirement on the height position of the supporting support plate 23 under various using working condition requirements can be met more easily. The lifting sleeve 213 can play a guiding and limiting effect on the upright post 211 in the lifting process, and the structural strength and stability of the support supporting plate 23 are improved.

Referring to fig. 3, in addition, a through hole 2131 is formed in one side of the lifting sleeve 213, and scale lines 2132 are formed around the through hole 2131 for observing the adjusted height and confirming the left-right balance.

Further, for convenience, when a special tool is not required, a worker may manually screw the lifting screw 214, and a hand-screwing structure is provided at one end of the lifting screw 214 outside the lifting sleeve 213. For example, the twist structure may be, but is not limited to, a plate, a ring, and the like.
