Description

Technical Field

[0001] The invention relates to the field of scissor fork lifting systems, and in particular to a scissor fork lifting system for a vehicle body floor assembly. Background Art

[0002] In daily production and life, it is often necessary to use a lifting system to lift objects in order to perform various tasks. The basic structure of the existing scissor-fork type belt lift is similar to that of the scissor-fork type hydraulic lift and is driven by a motor.

[0003] During the body processing process, the body floor assembly needs to be lifted up, so the lifting platform of the scissor fork lifting system needs to be against the body floor, the motor is started to unfold the scissor forks, and then the lifting platform rises to lift up the body floor assembly.

[0004] However, the existing scissor fork lifting system has the following problems during operation:

[0005] During the working process, the scissor fork is composed of multiple parts. The side of the scissor fork system is easily collided, and this part is relatively weak and easily damaged after the collision. Therefore, the service life of the scissor fork system is easily reduced after the collision.

[0006] During the supporting process, since the top of the scissor fork lifting system has to bear a large weight, the bottom of the existing scissor fork lifting system is not stable enough, which may easily lead to hidden dangers;

[0007] After work, the movable platform is in contact with the bottom of the vehicle, which is easily contaminated with a lot of dust and cannot be cleaned in time. Summary of the invention

[0008] The purpose of the present invention is to provide a scissor fork lifting system for a vehicle body floor assembly, and to provide a scissor fork lifting system that can increase the service life of the device, reduce safety hazards, and can clean the platform in time.

[0012] The protection assembly includes a driving disk, a driving handle, a driving rod, a lifting frame, an air delivery structure, an air delivery pipe, and a protection airbag. One side of the driving disk is connected to one end of the driving shaft. The driving handle is connected to the other side of the driving disk. One end of the driving rod is connected to one side of the driving handle. The lifting frame cooperates with the driving rod. The input end of the air delivery structure is connected to the lifting frame through a connecting rod. A plurality of the protection airbags are arranged in a straight line on one side of the scissor structure. One end of the air delivery pipe is connected to the output end of the air delivery structure, and the other end of the air delivery pipe is communicated with the protection airbag.

[0013] The first cleaning assembly includes a rotating communication ring, a connecting pipe, a cleaner, a nozzle, and a deployment structure. The rotating communication ring is arranged on one side of the scissor structure. The inside of the rotating communication ring is hollow and communicated with the protection airbag. The cleaner is movably arranged on the movable platform. A plurality of the nozzles are arranged on one side of the cleaner. One end of the deployment structure is connected to the cleaner, and the other end of the deployment structure is connected to one side of the scissor structure;

[0014] Among them, the rotating communication ring is divided into an inner layer and an outer layer. The inner layer rotates with the scissor structure. The outer layer is connected to the protection airbag and the connecting pipe. There is a channel between the inner and outer layers to transfer gas. During the rotation of the inner layer, it opens and closes.

[0015] The reinforcement assembly includes an output pipe, a cylinder, a piston, a telescopic device, a return spring, and a reinforcement block. There is an output head at the bottom of the protection airbag. A plurality of the cylinders are respectively arranged at the four corners of the bottom platform. One end of the output pipe is communicated with the output head, and the other end of the output pipe is communicated with the cylinder. The piston is movably arranged inside the cylinder. One end of the telescopic device is connected to the top of the piston, and the other end of the telescopic device is connected to the inner wall of the cylinder.

[0018] A number of protection airbags are provided, and the number of protection airbags is communicated through a connecting air pipe.

[0019] The air delivery structure is arranged on one side of the bottom platform and inside the scissor structure.

[0020] The present invention has the following beneficial effects:

[0021] In the process of lifting of the present invention, the driving motor drives the driving shaft to rotate through the pulley group. The rotation of the driving shaft drives the driving disk connected thereto to rotate. The rotation of the driving disk drives the driving handle to rotate. The rotation of the driving handle causes the driving rod to rotate. The driving rod cooperates with the lifting frame, and the driving rod moves in the lifting frame, thereby driving the lifting frame to move up and down cyclically, so that the air delivery structure works. Gas is input from the air delivery pipe into the protection airbag, and the protection airbag protects on the side of the scissor structure to protect the scissor structure from being collided from the side, improving the service life of the system, and being able to be interconnected with the scissor lift. Protection is carried out when the scissor is lifted, improving synchronization and automation.

[0022] After the present invention works, the driving motor rotates in the reverse direction, so that the scissor structure contracts. In the process of contraction of the scissor structure, the deployment structure gradually contracts, so that the cleaner moves upward, and the nozzle is aligned with the movable platform. The rotating communication ring is divided into an inner layer and an outer layer and has channel cooperation. When the scissor structure contracts to the initial position, the rotating communication ring is communicated, and gas enters the cleaner from the connecting pipe and then is ejected through the nozzle. When cleaning, the cleaning of the tabletop can be associated with the contraction of the scissor, and the tabletop can be cleaned more timely.

[0023] In the process of lifting of the present invention, gas is input from the air delivery pipe into the protection airbag. The gas in the protection airbag enters the output pipe through the output head, and then the gas in the output pipe enters the cylinder. The pressure formed by the gas in the cylinder causes the piston to move, thereby driving the reinforcement block connected to the piston to move downward. The surface of the reinforcement block is provided with many anti-slip blocks, which can improve the friction force, make the system more stable, reduce potential safety hazards, and through the drive of the protection airbag, the reinforcement process can be interconnected with the scissor lift. Reinforcement is carried out when the scissor is lifted, and the reinforcement stops when the scissor contracts, which is more flexible.

[0024] In the process of lifting, the deployment frame unfolds along with the scissor structure, so that the slider slides in the track. Then, when the scissor structure unfolds to an appropriate position, the positioning member can cooperate with the bottom plate and be locked for positioning. This can link the positioning process with the lifting process of the system, and the movement of the positioning member with the movement of the scissor structure, improving the accuracy of positioning.

[0025] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The working steps of a scissor lifting system for a vehicle body bottom plate assembly according to the present invention are as follows:

[0054] Lifting:

[0055] When it is necessary to support the vehicle body bottom plate, the driving motor 1301 is started. The driving motor 1301 drives the driving shaft 1302 to rotate through the pulley group 1304, and the driving shaft 1302 drives the rotating shaft in the scissor structure 1305 to rotate through the gear group 1303, so that the scissor structure 1305 unfolds, and thus the movable platform 120 is lifted;

[0056] Positioning:

[0057] During the lifting process, the deployment frame 1401 unfolds along with the scissor structure 1305, so that the slider 1403 slides in the track 1402. Then when the scissor structure 1305 unfolds to an appropriate position, the positioning member 1404 can cooperate with the bottom plate and be stuck for positioning;

[0058] Protection:

[0059] During the lifting process, the drive motor 1301 drives the drive shaft 1302 to rotate through the pulley set 1304. The rotation of the drive shaft 1302 drives the drive disk 1501 connected thereto to rotate. The rotation of the drive disk 1501 drives the drive handle 1502 to rotate. The rotation of the drive handle 1502 causes the drive rod 1503 to rotate. The drive rod 1503 cooperates with the lifting frame 1504, and the drive rod 1503 moves in the lifting frame 1504, thereby driving the lifting frame 1504 to move up and down cyclically, so that the gas transmission structure 1505 operates. Gas is input from the gas transmission pipe 1506 into the protection airbag 1507, and the protection airbag 1507 protects on the side of the scissor structure 1305;

[0060] Reinforcement:

[0061] During the lifting process, gas is input from the gas transmission pipe 1506 into the protection airbag 1507. The gas in the protection airbag 1507 will enter the output pipe 1701 through the output head 1707, and then the gas in the output pipe 1701 enters the cylinder 1702. The pressure formed by the gas in the cylinder 1702 will cause the piston 1703 to move, thereby driving the reinforcement block 1706 connected to the piston 1703 to move downward. The surface of the reinforcement block 1706 is provided with many anti-slip blocks, which can increase the friction force and make the system more stable;

[0062] After the work is completed, the telescopic device 1704 cooperates with the return spring 1705 to enable the reinforcement block 1706 to return to its original position after the pressure disappears;

[0063] Cleaning:

[0064] After the work is carried out, the drive motor 1301 rotates in the reverse direction, so that the scissor structure 1305 contracts. During the contraction of the scissor structure 1305, the unfolding structure 1605 gradually contracts, so that the cleaner 1603 moves upward. The nozzle 1604 is aligned with the movable platform 120. The rotary communication ring 1601 is divided into an inner layer and an outer layer and has channel cooperation. When the scissor structure 1305 contracts to the initial position, the rotary communication ring 1601 is communicated, and gas enters the cleaner 1603 from the connecting pipe 1602 and then is ejected through the nozzle 1604;

[0065] After the work is carried out, the tool needs to be cleaned. During the process of the lifting frame 1504 moving up and down with the scissor structure 1305, the mounting frame 1801 connected thereto will move up and down, so that the cleaning brush 1802 moves up and down continuously, and the tool can be cleaned.
