Description

Technical Field

[0001] The present invention relates to a lift, and particularly to a heavy-duty lift suitable for installation in a small space. Background Art

[0002] In the current automobile final assembly production line, during the transportation process of the final assembly body in the vertical and cross directions, a lifting and traversing device is often used to meet the requirements of automatic body transportation, which can reduce the occupied space of the transportation line and significantly improve production efficiency. The traditional lifting and traversing device generally uses a motor to drive an eccentric camshaft to drive the traversing conveyor to lift up and down to achieve the function of lifting and traversing the body. This technical solution requires a drive motor for the eccentric camshaft and occupies a large space. There is also a method of using vertically arranged cylinders to achieve the vertical lifting of the traversing machine, such as the patent document with the publication number CN218464714U named "A Lifting and Traversing Mechanism and a Transfer Machine System" and the patent document with the publication number CN207404360U named "Lifting and Transfer Device", which disclose a technical solution of using vertically arranged cylinders to achieve the vertical lifting of the traversing machine. The above two structures both require a large space to be reserved in the vertical direction and cannot be used for a conveyor with limited lifting space. How to reduce the occupied space of the lifting and traversing machine in the up and down directions has become a technical problem to be solved. Summary of the Invention

[0003] The present invention provides a heavy-duty lift that can be installed in a small space, and solves the technical problem of how to reduce the occupied space of the lift in the up and down directions.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A heavy-duty lift that can be installed in a small space, comprising a "day"-shaped base frame, a four-wheel transverse movement trolley, and a rectangular lifting frame. A guiding upright column is suspended at the bottom surface of each of the four corners of the rectangular lifting frame; on the "day"-shaped base frame, there are respectively arranged left and right reciprocating walking tracks corresponding to the wheels of the four-wheel transverse movement trolley and linear bearing seats corresponding to the four guiding upright columns. A transverse movement trolley driving cylinder mounting seat is arranged at the left part of the "day"-shaped base frame; on the rectangular vehicle body frame of the four-wheel transverse movement trolley, a wheel axle is arranged, and a lifting wheel and a walking wheel are respectively arranged on the wheel axle. The four-wheel transverse movement trolley is movably arranged on the left and right reciprocating walking tracks through the walking wheels. A transverse movement trolley driving cylinder is arranged on the transverse movement trolley driving cylinder mounting seat, and the rightward output shaft of the transverse movement trolley driving cylinder is connected to the left end of the rectangular vehicle body frame of the four-wheel transverse movement trolley; on the bottom end surface of the rectangular lifting frame, a horizontally-oriented wedge block is fixedly connected. The rectangular lifting frame is arranged directly above the four-wheel transverse movement trolley, and the horizontally-oriented wedge blocks on the left and right of the rectangular lifting frame are movably abutted against the lifting wheels. The lower ends of the guiding upright columns suspended on the rectangular lifting frame are movably inserted into the linear bearing seats.

[0006] The shaft end of the rightward output shaft of the transverse movement trolley driving cylinder is connected to the left end of the rectangular vehicle body frame of the four-wheel transverse movement trolley through an elbow joint.

[0007] The two rear walking wheels of the four-wheel transverse movement trolley are walking wheels with wheel rims, and the two front walking wheels of the four-wheel transverse movement trolley are walking wheels without wheel rims.

[0008] In the present invention, through the horizontally-arranged driving cylinder, the four-wheel transverse movement trolley is driven to move left and right.

[0017] The present invention will be described in detail below with reference to the accompanying drawings:

[0018] A heavy-duty lift that can be installed in a small space, including a "day"-shaped base frame 1, a four-wheel transverse movement trolley 4, and a rectangular lifting frame 10. A guiding column 11 is suspended at the bottom surface of each of the four corners of the rectangular lifting frame 10, and the rectangular lifting frame 10 and the four guiding columns 11 form an integral body. On the "day"-shaped base frame 1, there are respectively provided left and right reciprocating walking tracks 2 corresponding to the wheels of the four-wheel transverse movement trolley 4 and linear bearing seats 3 corresponding to the four guiding columns. The left and right reciprocating walking tracks 2 are arranged on the front outer side and the rear outer side of the "day"-shaped base frame 1. The left and right reciprocating walking tracks 2 are arranged in sections, and each section of the left and right reciprocating walking track 2 corresponds to a wheel. Since the reciprocating walking stroke of the wheel is limited, the length of the left and right reciprocating walking track 2 does not need to be too long. The linear bearing seats 3 provided on the "day"-shaped base frame 1 are arranged in one-to-one correspondence with the guiding columns 11. The guiding column 11 is vertically and movably inserted into the linear bearing seat 3 to realize the lifting guidance of the rectangular lifting frame 10. A transverse movement trolley driving cylinder mounting seat 8 is provided on the left part of the "day"-shaped base frame 1. A wheel axle 13 is provided on the rectangular vehicle body frame of the four-wheel transverse movement trolley 4. A lifting wheel 14 and walking wheels are respectively provided on the wheel axle 13. The walking wheels include two front side walking wheels 6 and two rear side walking wheels 5. These four walking wheels are correspondingly matched with the left and right reciprocating walking tracks. The lifting wheel 14 is arranged outside the walking wheels and is suspended. The four-wheel transverse movement trolley 4 is movably arranged on the left and right reciprocating walking tracks 2 through the walking wheels. A transverse movement trolley driving cylinder 7 is provided on the transverse movement trolley driving cylinder mounting seat 8. The rightward output shaft of the transverse movement trolley driving cylinder 7 is connected to the left end of the rectangular vehicle body frame of the four-wheel transverse movement trolley 4. By controlling the extension and retraction of the output shaft of the transverse movement trolley driving cylinder 7, the left and right movement of the four-wheel transverse movement trolley 4 is realized. A horizontal wedge block 12 is fixedly connected to the bottom end surface of the rectangular lifting frame 10. The rectangular lifting frame 10 is arranged directly above the four-wheel transverse movement trolley 4, and the left and right horizontally arranged wedge blocks 12 on the rectangular lifting frame 10 are movably abutted against the lifting wheels 14. The lower end of the guiding column 11 suspended on the rectangular lifting frame 10 is movably inserted into the linear bearing seat 3. When the transverse movement trolley driving cylinder 7 extends, the four-wheel transverse movement trolley 4 moves to the right, and the lifting wheel 14 jacks up the rectangular lifting frame 10 through the cooperation with the wedge block 12. The rectangular lifting frame 10 realizes the lifting under the limit cooperation of the linear bearing seat 3 and the guiding column 11. When the transverse movement trolley driving cylinder 7 retracts, the four-wheel transverse movement trolley 4 moves to the left, and the lifting wheel 14 jacks down the rectangular lifting frame 10 through the cooperation with the wedge block 12. The rectangular lifting frame 10 realizes the lowering under the limit cooperation of the linear bearing seat 3 and the guiding column 11.

[0019] The shaft end of the rightward output shaft of the transverse movement trolley driving cylinder 7 is connected to the left end of the rectangular vehicle body frame of the four-wheel transverse movement trolley 4 through an elbow joint 9, so as to realize a flexible connection between the two.

[0020] The two rear running wheels 5 of the four-wheel transverse transfer trolley 4 are running wheels with wheel rims, and the two front running wheels 6 of the four-wheel transverse transfer trolley 4 are running wheels without wheel rims, so as to realize the limit of left and right movement.
