Description

Technical Field

[0001] The utility model relates to the technical field of automobile transportation, in particular to a skid-changing lift and a skid-changing system. Background Art

[0002] The conveying equipment in the workshops of automobile factories are all highly automated conveyor lines. The workshops of automobile factories are divided into welding workshops, painting workshops, and assembly workshops. Different workshops generally use different body carriers due to different processing techniques for the body. In some special cases, such as energy conservation and emission reduction, process requirements, etc., the carriers may be replaced in the same workshop.

[0003] The traditional handover position is to completely separate the carrier from the vehicle body, and then use auxiliary lifting + transfer forks or side lifters to lift the vehicle body to a certain height to achieve carrier replacement. However, due to structural limitations, the skid body is added under the vehicle body support carrier, and the vehicle body is not allowed to be lifted too high. In addition, in the case of limited space, the lift is generally split to ensure the lifting stroke. The split type not only requires multiple motors to lift, but also has poor synchronization of multiple motors. This results in the traditional vehicle replacement method being unable to solve the need to add a skid body under the vehicle body support carrier. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a skid-changing lift and a skid-changing system, which can realize the demand for adding a skid body under a vehicle body support carrier under the condition of limited structure and space, and can effectively solve the problems in the background technology.

[0011] As a preferred technical solution of the utility model, the lifting mechanism includes a driving motor, a driving sprocket, a driven sprocket, a chain, a transmission shaft, a crank and a top wheel. The driving motor is arranged on one side of the base, and two driving sprockets are arranged on the output shaft of the driving motor. The number of the driven sprockets is two, and the two driven sprockets are symmetrically arranged on both sides of the driving sprocket. A chain is sleeved between the driving sprocket and the driven sprocket, the transmission shaft is fixed to one end of the driven sprocket, and the other end of the transmission shaft passes through a bearing seat, and the outer side surfaces of both ends of the transmission shaft are sleeved with cranks, and a top wheel is fixed to one end of the crank, and the top wheel is in contact with the lower surface of the lifting frame.

[0012] As a preferred technical solution of the utility model, fixing frames are provided at the lower ends of both sides of the lifting frame, grooves are provided in the fixing frames, and the top wheels are located in the grooves.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments (for the convenience of description and understanding, the following is a schematic diagram of the present invention). Figure 2 Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0023] See also Figure 1-3 The utility model provides a technical solution: a skid-changing lift, comprising a base 11, a lifting frame 12 and a lifting mechanism, wherein the base 11, the lifting frame 12 and the lifting mechanism together constitute a skid-changing lift mechanism 1, wherein the base 11 is arranged on both sides of a transverse chain bed 2, and the lifting frame 12 is arranged above the base 11, and is used to lift or lower a vehicle body 7. The lifting mechanism 16 is arranged between the base 11 and the lifting frame 12, and is used to drive the lifting frame 12 to move up and down.

[0024] A plurality of cross beams 13 are arranged on the base 11 , and the cross beams 13 span the entire transverse chain bed 2 . The middle position of the cross beams 13 is in a "J" shape, so that the cross beams 13 avoid the through-length axis of the transverse chain bed 2 when spanning the entire transverse chain bed 2 .

[0025] Furthermore, avoidance beams 15 are symmetrically arranged at both ends of the lifting frame 12. The avoidance beams 15 are concave at both ends and convex in the middle. The concave structure in the middle of the avoidance beams 15 prevents the lifting frame 12 from touching the full-length axis of the transverse chain bed 2 when falling. The concave structures on both sides of the avoidance beams 15 make the low position low enough so that the vehicle body 7 can pass smoothly on the transverse chain bed 2.

[0026] The lifting mechanism 16 includes a driving motor 161, a driving sprocket, a driven sprocket 162, a chain 163, a transmission shaft 164, a crank 165 and a top wheel 166. The driving motor 161 is arranged on one side of the base 11. Two driving sprockets are arranged on the output shaft of the driving motor 161. There are two driven sprockets 162. The two driven sprockets 162 are symmetrically arranged on both sides of the driving sprocket. The chain 163 is sleeved between the driving sprocket and the driven sprocket 162. The transmission shaft 164 is fixed to the driven sprocket 162. One end of the transmission shaft 164 is provided, and the other end of the transmission shaft 164 passes through a bearing seat 169. Cranks 165 are sleeved on the outer sides of both ends of the transmission shaft 164. A top wheel 166 is fixed to one end of the crank 165. The top wheel 166 contacts the lower surface of the lifting frame 12. The rotation of the two transmission shafts 164 is realized through the sprocket-chain transmission, thereby driving the crank 165 to rotate, changing the height position of the top wheel 166, and realizing the lifting or lowering of the lifting frame 12. In the case of limited space, the effective stroke required for actual use can also be guaranteed.

[0027] Furthermore, in order to ensure the support stability of the top wheel 166 on the lifting frame 12 , a fixing frame 167 is provided at the lower end of both sides of the lifting frame 12 , and a groove 168 is provided in the fixing frame 167 , and the top wheel 166 is located in the groove 168 .

[0028] Furthermore, in order to ensure that the lifting frame 12 accurately supports the front body frame 5 and the rear body frame 6 that carry the vehicle body 7, positioning plates 14 are provided at the four corners of the upper end of the lifting frame 12, and the positioning plates 14 are provided with limiting grooves that cooperate with the front body frame 5 and the rear body frame 6 that carry the vehicle body 7.

[0029] like Figure 4-5 A skid changing system includes a skid changing lifting mechanism 1, a transverse chain bed 2 and a roller bed 3. The roller bed 3 is arranged on one side of the transverse chain bed 2. The working process is as follows:

[0030] The vehicle body 7 is fixed on the front vehicle body support 5 and the rear vehicle body support 6, and runs horizontally on the transverse chain bed 2 together, and moves to the top of the skid-changing lifting mechanism 1. The driving motor 161 in the skid-changing lifting mechanism 1 is started, and the two transmission shafts 164 are rotated under the transmission of the sprocket-chain, thereby driving the two cranks 165 and the top wheel 166 on each transmission shaft 164 to rotate upward, and lift the lifting frame to a specified height. At this time, a suitable space is left between the front vehicle body support 5 and the rear vehicle body support 6 and the transverse chain bed 2, and the skid body 4 is transported to the specified position directly below the front vehicle body support 5 and the rear vehicle body support 6 through the roller bed 3, and the driving motor 161 is reversely operated to lower the lifting frame 12 until the front vehicle body support 5 and the rear vehicle body support 6 fall on the skid body 4.

[0031] The utility model can be conveniently operated, occupies little space when in use, and is easy to operate and use; by optimizing the structure of the lifting frame 12, it is possible to ensure the effective lifting stroke of the lift even when space is limited, and at the same time, the purpose of switching between different carriers of the transverse chain bed 2 and the roller bed 3 is achieved within the limited space of a single workstation.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
