A stop bar is installed below the grippers to engage with the cantilever arm limit stops. This patent enables lifting operations on the cab, but existing lifting devices suffer from defects such as unstable connections, poor stability, and low reliability. While the improved lifting device can meet the requirements of diversity and stability, it has the disadvantages of complex structure and high manufacturing cost. Utility Model Content

[0003] One of the technical problems that this disclosure aims to solve is that the existing cab-mounted lifting equipment has a complex structure and low lifting stability.

[0004] To solve the above-mentioned technical problems, this disclosure provides a cab transfer lifting device, which includes an upper frame assembly, a transfer hook, a fixed lifting seat, and a movable lifting seat. The transfer hook is fixedly installed on the upper end face of the upper frame assembly. A first mounting arm and a second mounting arm are symmetrically arranged on both sides of the upper frame assembly. The fixed lifting seat is fixedly installed on the first mounting arm and extends towards the second mounting arm. A fixed angle X is formed between the fixed lifting seat and the first mounting arm, where 90° ≥ X ≥ 80°. The movable lifting seat is rotatably mounted on the second mounting arm. The second mounting arm is rotated from 0° to 90°. A fixed connecting shaft is provided on the second mounting arm. A rotating connecting sleeve is provided on the movable lifting seat. The rotating connecting sleeve is fitted onto the fixed connecting shaft. The rotating connecting sleeve rotates around the axis of the fixed connecting shaft. The rotating connecting sleeve slides along the axis of the fixed connecting shaft. A limit post is provided on the fixed connecting shaft. A limit notch is provided on the rotating connecting sleeve. When the limit post is engaged in the limit notch, the movable lifting seat faces the direction of the first mounting arm. An angle Y is formed between the movable lifting seat and the second mounting arm, where 90° ≥ Y ≥ 80°.

[0005] In some embodiments, the upper end face of the movable hoisting base is provided with a hoisting base connecting lug, the second mounting arm is provided with a mounting arm connecting lug, and a tension spring is sleeved between the hoisting base connecting lug and the mounting arm connecting lug.

[0006] In some embodiments, the movable hoisting base is provided with two rotating connecting sleeves, and a limiting notch is provided on the same side of the two rotating connecting sleeves respectively. The fixed connecting shaft is provided with two limiting posts, and the two limiting posts simultaneously engage or disengage with the two limiting notches.

[0007] In some embodiments, both the included angle X and the included angle Y are set to 90°.

[0008] In some embodiments, the upper frame assembly includes a long mounting beam and short mounting crossbeams. Two long mounting beams are provided and are arranged parallel to each other. Multiple short mounting crossbeams are provided and are symmetrically arranged between two long mounting beams. Each end of a long mounting beam is provided with a short mounting crossbeam edge seal. The first mounting arm and the second mounting arm are respectively vertically installed at both ends of the long mounting beam.

[0009] In some embodiments, the first mounting arm and the second mounting arm form right angles with the upper frame assembly, respectively.

[0010] In some embodiments, the upper frame assembly further includes cross reinforcing ribs disposed between two long mounting beams, with the intersection of the cross reinforcing ribs located at the center of the upper frame assembly, and the transfer hook fixedly installed at the intersection of the cross reinforcing ribs.

[0011] In some embodiments, the lower end of the transfer hook is provided with a lifting threaded rod, and the intersection of the cross reinforcing ribs is provided with a threaded groove that matches the lifting threaded rod. The transfer hook is helically fixed on the cross reinforcing ribs.

[0012] In some embodiments, the upper surfaces of the fixed lifting base and the movable lifting base are respectively provided with limiting fixtures.

[0013] In some embodiments, the limiting fixture is made of rubber.

[0014] The cab transfer lifting device provided in this disclosure, through the above technical solution, has the following beneficial effects:

[0015] Firstly, this solution includes a fixed lifting base and a movable lifting base. The second mounting arm has a fixed connecting shaft, and the movable lifting base has a rotating connecting sleeve. The rotating connecting sleeve is fitted onto the fixed connecting shaft and rotates around the axis of the fixed connecting shaft. The rotating connecting sleeve slides along the axis of the fixed connecting shaft. The fixed connecting shaft has a limit post, and the rotating connecting sleeve has a limit notch. When the limit post is engaged in the limit notch, the movable lifting base and the second mounting arm form a supportable angle, thus enabling the lifting of the cab. When the limit post is disengaged from the limit notch, the movable lifting base can rotate on the second mounting arm, facilitating the adjustment of the upper frame assembly to the cab by the operators.

[0016] Secondly, this design features a hoisting seat connecting lug on the upper surface of the movable hoisting seat and an mounting arm connecting lug on the second mounting arm. A tension spring is fitted between the hoisting seat connecting lug and the mounting arm connecting lug. This tension spring provides an upward pulling force to the movable hoisting seat, allowing workers to more accurately reset the movable hoisting seat after rotation using the elasticity of the limiting spring. Furthermore, when the limiting post is embedded in the limiting notch, the mounting arm connecting lug and the hoisting seat connecting lug are on the same vertical plane. Therefore, when the limiting post is embedded in the limiting notch, the tension spring is at its minimum tension distance. The aforementioned tension spring effectively generates tension to keep the limiting post embedded in the limiting notch, preventing the limiting post from falling out of the limiting notch.

[0033] like Figure 1-6 As shown, the cab transfer spreader includes an upper frame assembly 1, a transfer hook 2, a fixed lifting seat 3, and a movable lifting seat 4. The transfer hook 2 is fixedly installed on the upper end face of the upper frame assembly 1. The transfer hook 2, in conjunction with lifting equipment, can lift the entire cab transfer spreader. A first mounting arm 11 and a second mounting arm 12 are symmetrically arranged on both sides of the upper frame assembly 1. The fixed lifting seat 3 is fixedly installed on the first mounting arm 11 and extends towards the second mounting arm 12. The movable lifting seat 4 is rotatably mounted on the second mounting arm 12. The cooperation between the fixed lifting seat 3 and the movable lifting seat 4 can support and lift the cab. A fixed connecting shaft 121 is provided on the second mounting arm 12, and a rotating connecting shaft 121 is provided on the movable lifting seat 4. Connecting sleeve 41 is mounted on fixed connecting shaft 121. The rotating connecting sleeve 41 rotates around the axis of fixed connecting shaft 121. The rotating connecting sleeve 41 slides along the axis of fixed connecting shaft 121. A limit post 1211 is provided on fixed connecting shaft 121, and a limit notch 411 is provided on rotating connecting sleeve 41. When the limit post 1211 is embedded in the limit notch 411, the movable lifting seat 4 and the second mounting arm 12 form a supportable angle, thereby enabling the lifting of the cab. When the limit post 1211 is embedded in the unsupported limit notch 411, the movable lifting seat 4 can rotate on the second mounting arm 12, thereby facilitating the adjustment of the upper frame assembly 1 to the cab by the operator.

[0034] In some embodiments, a fixed angle X is formed between the fixed lifting base 3 and the first mounting arm 11, where 90° ≥ X ≥ 80°. Preferably, the angle between the fixed lifting base 3 and the first mounting arm 11 is set to 90° to ensure that the fixed lifting base 3 provides stable support for the cab and facilitates transportation.

[0035] In some embodiments, the movable lifting seat 4 rotates 0° to 90° on the second mounting arm 12. In some cases, the movable lifting seat 4 rotates 0° to 180° on the second mounting arm 12 to adapt to different states of the movable lifting seat 4 when adjusting its position. When the limiting post 1211 is engaged in the limiting notch 411, the movable lifting seat 4 faces the first mounting arm 11, and an angle Y is formed between the movable lifting seat 4 and the second mounting arm 12, where 90°≥Y≥80°. The angle between the movable lifting seat 4 and the second mounting arm 12 is preferably set to 90° to ensure that the movable lifting seat 4 provides stable support and transportation for the cab.

[0036] In some embodiments, the upper end face of the movable lifting base 4 is provided with a lifting base connecting ear 42, and the second mounting arm 12 is provided with a mounting arm connecting ear 122. A tension spring 5 is sleeved between the lifting base connecting ear 42 and the mounting arm connecting ear 122. The tension spring 5 can provide an upward pulling force to the movable lifting base 4, so the operator can use the elastic force of the limit spring to make the reset of the movable lifting base 4 after rotation more accurate.

[0037] In the above embodiment, when the limiting post 1211 is embedded in the limiting notch 411, the mounting arm connecting ear 122 and the lifting seat connecting ear 42 are on the same vertical plane. Therefore, when the limiting post 1211 is embedded in the limiting notch 411, the tension spring 5 is in the minimum tension distance state. The tension spring 5 can effectively generate tension to make the limiting post 1211 embedded in the limiting notch 411, preventing the limiting post 1211 from falling out of the limiting notch 411.

[0038] In some embodiments, the movable lifting base 4 is provided with two rotating connecting sleeves 41, and a limiting notch 411 is provided on the same side of each of the two rotating connecting sleeves 41. The fixed connecting shaft 121 is provided with two limiting posts 1211, thereby balancing the connection stability between the movable lifting base 4 and the second mounting arm 12.

[0039] Based on this, the two limiting posts 1211 simultaneously engage or disengage with the two limiting notches 411. For example, the limiting notches 411 on the two rotating connecting sleeves 41 are respectively set on the left or right side of the two rotating connecting sleeves 41, and the two limiting posts 1211 are respectively set on the left or right side of the two rotating connecting sleeves 41. When the limiting notches 411 and the limiting posts 1211 are engaged with each other, the two limiting posts 1211 are simultaneously embedded in the limiting notches 411. When the limiting notches 411 and the limiting posts 1211 are disengaged, the two limiting posts 1211 simultaneously slide out of the limiting notches 411.

[0040] In some embodiments, the upper frame assembly 1 includes a long mounting beam 13 and a short mounting crossbeam 14. Two long mounting beams 13 are provided and are arranged parallel to each other. Multiple short mounting crossbeams 14 are provided and are symmetrically arranged between two long mounting beams 13. A short mounting crossbeam 14 is provided at each end of the long mounting beam 13 to seal the edge. The first mounting arm 11 and the second mounting arm 12 are respectively vertically installed at the two ends of the long mounting beam 13, thereby providing sufficient support.

[0041] In some embodiments, the first mounting arm 11 and the second mounting arm 12 form right angles with the upper frame assembly 1, thereby generating sufficient structural strength and improving the lifting stability of the transfer spreader on the cab.

[0042] In some embodiments, the upper frame assembly 1 also includes a cross reinforcing rib 15, which is disposed between two long mounting beams 13. The cross reinforcing rib 15 can increase the structural strength of the upper frame assembly 1. The intersection of the cross reinforcing rib 15 is located at the center of the upper frame assembly 1. The transfer hook 2 is fixedly installed at the intersection of the cross reinforcing rib 15, thereby improving the uniformity of the lifting structure of the upper frame assembly 1 and further ensuring the transportation stability of the lifting equipment.

[0043] In some embodiments, the lower end of the transfer hook 2 is provided with a lifting threaded rod, and the intersection of the cross reinforcing ribs 15 is provided with a threaded groove that matches the lifting threaded rod. The transfer hook 2 is spirally fixed on the cross reinforcing ribs 15. When the lifting equipment is not in use, the transfer hook 2 can be removed, thereby facilitating the storage of the lifting equipment.

[0044] In some embodiments, the upper surfaces of the fixed lifting base 3 and the movable lifting base 4 are respectively provided with limiting fixtures 6. During lifting, the limiting fixtures 6 contact the cab to lift the cab. In addition, the limiting fixtures 6 are made of rubber to prevent damage to the cab during lifting and transportation.

[0045] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
