Description

Technical Field

[0001] The utility model relates to a logistics transportation device, in particular to a transfer device for reciprocating vertical lifting of a cage truck. Background Art

[0002] In the field of automated logistics transportation, a cage truck is a unit mobile container device for transporting and storing materials, equipped with four casters, and is often used for logistics distribution in large supermarkets or logistics turnover between factory processes. Nowadays, storage rooms or warehouses often store materials through shelves. Therefore, in addition to cage trucks, a lifting device is often required to transport materials in horizontal and vertical directions.

[0003] Of course, existing manufacturers have also introduced many products that directly combine a lifting device with a cage truck to meet the demand for efficient material transportation. However, there are still many drawbacks, such as: ① Lack of a safety device. When the cage truck moves, it often jolts, so the lifting platform installed on it is prone to falling due to the jolts, posing a great safety hazard. ② The lifting device is prone to jamming. In long-term use and in complex working environments, it is difficult for the lifting platform to maintain a horizontal state, which easily leads to problems such as jamming or misalignment of the lifting platform.

[0004] To solve the above technical problems, the applicant has designed a transfer device for reciprocating vertical lifting of a cage truck. Summary of the Utility Model

[0007] A flip-up safety hook is provided on the side of the lifting platform. One end of the safety hook is connected to the jacking component through the connecting rope. The safety hook has a hook portion. When the connecting rope breaks, the safety hook can be flipped under the action of gravity, and at the same time, its hook portion can be clamped on the limit block.

[0008] Wherein, it further includes a flat layer positioning mechanism. The flat layer positioning mechanism includes: an electric push rod, a travel switch, a PLC control system, and a number of limit pin holes arranged on the frame body;

[0009] The electric push rod is installed at the four corners of the lifting platform. The travel switch is installed on the movement stroke of the lifting platform and is electrically connected to the PLC control system. The PLC control system can control the telescopic state of the electric push rod. Furthermore, the PLC control system can receive the control signal of the travel switch and control the limit pin of the electric push rod to stretch in and out of the limit hole.

[0010] Among them, the travel switch includes an upper limit travel switch and a lower limit travel switch, and the upper limit travel switch and the lower limit travel switch are arranged up and down.

[0011] Among them, the frame body includes: a bottom cross beam, a top cross beam, vertical beams, and several middle cross beams. The bottom cross beam and the top cross beam are enclosed and connected by the vertical beams to form a rectangular frame, and the middle cross beam is connected between the vertical beams.

The oil cylinder 21 is fixed to the bottom of the frame body 1 and can drive the jacking component 22 to lift and lower.

[0026] A flip-up safety hook 31 is provided on the side of the lifting platform 3. One end of the safety hook 31 is connected to the jacking component 22 through the connecting rope 23. The safety hook 31 has a hook portion 311. When the connecting rope 23 breaks, the safety hook 31 can be flipped under the action of gravity, and at the same time, its hook portion 311 can be clamped on the limit block 11, thereby preventing the lifting platform 3 from falling from a high place.

[0027] It should be particularly noted that the connecting rope 23 in this embodiment is a steel wire rope. Of course, it can also be made of other materials, and this embodiment is not limited thereto.

[0028] Please combine Figure 1 Refer to Figure 3, the frame body 1 includes: a bottom cross beam 12, a top cross beam 13, vertical beams 14, and several middle cross beams 15. The bottom cross beam 12 and the top cross beam 13 are enclosed and connected by two vertical beams 14 to form a rectangular frame, and the middle cross beams 15 are connected between the vertical beams 14.

[0029] Preferably, a connecting rope limiting block 151 is provided on the middle cross beam. A rope passing hole is provided on the connecting rope limiting block 151, and the connecting rope 23 passes through the rope passing hole. The connecting rope limiting block 151 can prevent the connecting rope 23 from shaking during the lifting and lowering of the lifting platform.

[0030] As Figure 4 shown, it further includes a leveling positioning mechanism 4. The leveling positioning mechanism 4 includes: an electric push rod 41, a travel switch 42, a PLC control system, and several limit pin holes 43 provided on the frame body 1. The leveling positioning mechanism 4 can ensure that the bearing surface of the lifting platform 3 is in a horizontal state and further prevent the lifting platform 3 from falling.

[0031] The electric push rod 41 is installed at the four corners of the lifting platform 3. The travel switch 42 is installed on the movement stroke of the lifting platform 3 and is electrically connected to the PLC control system. The PLC control system can be controlled to connect the electric push rod 41. Furthermore, the PLC control system can receive the control signal of the travel switch 42 and control the electric push rod 41 to extend and retract in the limit hole 43.

[0032] The travel switch 42 includes an upper limit travel switch 421 and a lower limit travel switch 422. The upper limit travel switch 421 and the lower limit travel switch 422 are arranged on the vertical lifting stroke of the lifting platform.

[0033] As Figure 4 (A), Figure 4 (B) shown, when the lifting platform 3 moves upward and reaches the position where the upper limit travel switch 421 is located, the upper limit travel switch 421 sends a control signal to the PLC control system. The PLC control system then controls the lifting platform 3 to stop rising. At the same time, the electric push rod 41 extends the bolt, and then the lifting platform 3 will be fixed at the current height. When the lifting platform 3 descends and moves to the position where the lower limit travel switch 422 is located, the lower limit travel switch 422 sends a control signal to the PLC control system. The PLC control system then controls the lifting platform 3 to stop descending. At the same time, the electric push rod 41 extends the bolt, and the lifting platform 3 is fixed at the lower edge of the limit hole 43.

The pulley fixing plate 2221 is mounted on the jacking member 22, and the pulley 2222 is rotatably mounted on the sliding fixing plate 2221 through the pin 2223.

[0035] As Figure 5 As shown in (B), a guide wheel groove seat 141 is provided on the inner side wall of the vertical beam 14. Guide wheels 221 are provided at both ends of the jacking member 22. The jacking member 22 is liftably mounted in the frame body 1 through the sliding fit of the guide wheels 221 and the guide wheel groove seat 141. The guide wheels 221 and the guide wheel groove seat 141 keep the lifting platform in a horizontal posture during the lifting process, avoiding the problem of jamming due to the inclination of the lifting platform.

[0036] Please refer to Figure 1 , a rolling shutter mechanism 32 is provided on the lifting platform 3, and thus the opening side of the lifting platform 3 can be opened and closed through the rolling shutter mechanism 32.

[0037] More preferably, the lifting platform 3 is provided with a rotating clamping block, which can limit the lifting platform 3. Thus, during the lifting process of the lifting platform 3, the lifting platform slides out from the gap between the middle cross beams 15.
