Description

Technical Field

[0001] The invention relates to the technical field of cranes, in particular to a steel cage hoisting device. Background Art

[0002] The hoisting operation of the steel cage is an important link in its installation process. This process usually relies on a crane. Most traditional cranes include basic structures such as a body, a large hook and a small hook. The large hook is used to hoist the upper part of the steel cage, while the small hook is used to assist in hoisting the lower part of the steel cage.

[0003] However, in actual operation, this traditional hoisting method has the following problems: Lack of automated control of the small hook release process: After the steel cage is hoisted to the predetermined position and is in a vertical state, manual operation is required to release the small hook so that the steel cage can be completely placed on the foundation. This step not only increases the workload of the construction workers, but more importantly, it brings potential safety hazards. Since the steel cage is often heavy and in an aerial working environment, the slightest carelessness in the process of manually releasing the small hook may lead to serious consequences such as the instability of the steel cage or injuries to construction workers;

[0004] The main reasons for the above problems are:

[0005] Technical limitations: Traditional crane designs mainly focus on the basic functions of lifting and carrying heavy objects. However, for components with a specific shape and weight, such as steel cages, there is a lack of targeted automated control mechanisms. In particular, for the release process of the small hook, traditional cranes usually do not have integrated advanced technologies for automatic release or remote control, which results in reliance on manual on-site operations.

[0006] Inadequate safety design: In the early stages of crane design, the safety needs of operators in high-altitude working environments may not have been fully considered. There was a lack of safety protection measures and automated solutions for the small hook release process, which made it necessary for construction workers to perform manual operations in a high-risk environment, increasing the possibility of accidents.

[0007] Work efficiency and cost considerations: Although the introduction of automated control technology can improve work efficiency and safety, this is also accompanied by an increase in costs. Traditional crane manufacturers may not include advanced automated control systems in standard configurations for cost control reasons, resulting in most cranes on the market still relying on manual operation.

[0008] In summary, the problems existing in traditional cranes in steel cage hoisting operations are mainly due to many factors such as technical limitations, insufficient safety design, work efficiency and cost considerations. For this reason, we propose a steel cage hoisting device. Summary of the invention

A fixed cavity is arranged between the two rotating rods, and the secondary chain is connected to the fixed cavity.

[0018] In some embodiments, the adjustment assembly includes two rotating shafts respectively rotatably arranged on the side of the mounting frame away from the supporting frame, the two clamping plates are respectively arranged on the rotating shafts, and the mounting frame is provided with a transmission member for controlling the rotation of the two rotating shafts and the clamping plates.

DETAILED DESCRIPTION

[0039] 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, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1-Figure 9 , the present invention provides a technical solution:

[0041] A steel cage hoisting device includes a body 1, a large hook 10 and a small hook 11. The body 1 is a crane, which is used to control the large hook 10 and the small hook 11 to work and provide a power source. The device also includes:

[0042] A main hoisting unit 2, which is arranged on the big hook 10 and is used to hoist the upper part of the steel cage;

[0043] The main hanging unit 2 includes a main chain 21 arranged on the big hook 10, a fixing plate 22 is arranged at the bottom of the main chain 21, and branch chains 23 are arranged at both ends of the fixing plate 22, and the two ends of the branch chains 23 are respectively connected to the two sides of the upper part of the steel cage;

[0044] Auxiliary hanging unit 3, the auxiliary hanging unit 3 is arranged on the small hook 11;

[0045] Two clamping plates 12, both of which are arranged on the auxiliary hanging unit 3. Generally speaking, the clamping position of the clamping plates 12 is one-third of the lower part of the steel cage. The opposite sides of the two clamping plates 12 (i.e., the sides in contact with the steel cage) are provided with arc grooves for limiting the movement of the steel cage after being clamped;

[0046] The auxiliary hanging unit 3 is used to drive the two clamping plates 12 to clamp the lower part of the steel cage, and after the steel cage is in a vertical state, control the two clamping plates 12 to separate, thereby canceling the connection between the small hook 11 and the steel cage;

[0047] The auxiliary suspension unit 3 includes an auxiliary chain 31 arranged on the small hook 11, a mounting frame 32 is arranged between the auxiliary chain 31 and the clamping plate 12, a swinging member 4 is arranged on the mounting frame 32, and is connected to the mounting frame 32 and the auxiliary chain 31 respectively, and is used to control the angle adjustment between the mounting frame 32 and the auxiliary chain 31, an adjustment component 5 is arranged on the mounting frame 32, and is used to drive the two clamping plates 12 to adjust synchronously, and a separation control component 7 is arranged on the mounting frame 32, and is used to control the operation of the adjustment component 5;

[0048] The swing member 4 includes two support frames 41 respectively arranged on both sides of the mounting frame 32, and a rotating rod 42 is rotatably arranged on each support frame 41, and a fixed cavity 43 is arranged between the two rotating rods 42, and the secondary chain 31 is connected to the fixed cavity 43;

[0049] The adjustment assembly 5 includes two rotating shafts 51 respectively rotatably arranged on the side of the mounting frame 32 away from the support frame 41, and the two clamping plates 12 are respectively arranged on the rotating shafts 51. The mounting frame 32 is provided with a transmission member 6 for controlling the rotation of the two rotating shafts 51 and the clamping plates 12;

[0050] The transmission member 6 includes a shift rack 61 slidably disposed in the middle of the mounting frame 32, and a transmission gear 62 used in conjunction with the shift rack 61 is disposed on each of the two rotating shafts 51. A torsion spring 63 is sleeved on the outer side of each rotating shaft 51, and both ends of the torsion spring 63 are respectively connected to the transmission gear 62 and the mounting frame 32;

[0051] The separation control assembly 7 includes a cylindrical cavity 71 arranged on the mounting frame 32, the fixed cavity 43 and the cylindrical cavity 71 are connected by a hose, a shifting member 8 connected to the shifting rack 61 is arranged on the cylindrical cavity 71, and is used to drive the shifting rack 61 to shift and adjust, an abutment plate 72 is arranged on one side of the mounting frame 32, and an extrusion member 9 is arranged between the fixed cavity 43 and the abutment plate 72, and is used to drive the shifting member 8 to work when it contacts the abutment plate 72;

[0052] The displacement member 8 includes a piston rod 81 slidably disposed in the cylindrical cavity 71. The piston rod 81 movably penetrates the mounting frame 32 and is connected to the displacement rack 61. A detachable rubber top block is provided on the side of the displacement rack 61 close to the steel cage, which is used to preferentially contact the steel cage during displacement.

[0053] The extrusion member 9 includes a piston rod 91 slidably arranged in the fixed cavity 43, a fitting plate 92 in contact with the abutment plate 72 is arranged at the end of the piston rod 91, a return spring 93 is arranged in the fixed cavity 43, and the two ends of the return spring 93 are respectively connected to the piston rod 91 and the fixed cavity 43. After the fitting plate 92 contacts the abutment plate 72, it is squeezed, so that the gas in the fixed cavity 43 is pushed into the cylindrical cavity 71 through the hose, thereby driving the piston rod 81 to work and shifting the shift rack 61 at the bottom of the piston rod 81.

[0054] When in use, the crane body 1 is operated to lift the steel cage through the main lifting unit 2 on the big hook 10 and the auxiliary lifting unit 3 on the small hook 11. The main lifting unit 2 is composed of a main chain 21, a fixing plate 22 and a branch chain 23. The two ends of the branch chain 23 are respectively connected to the two sides of the upper part of the steel cage to ensure the stability of the steel cage during the lifting process.

[0055] At the same time, the auxiliary hanging unit 3 on the small hook 11 starts to work. The auxiliary hanging unit 3 includes a secondary chain 31, a mounting frame 32, a swing member 4, an adjustment component 5 and a separation control component 7. The swing member 4 is connected to the secondary chain 31 through a rotating rod 42 and a fixed cavity 43 on two support frames 41, and the angle between the rotating rod 42 and the mounting frame 32 can be changed;

[0056] The adjustment component 5 includes a rotating shaft 51, a transmission gear 62, a torsion spring 63 and a transmission member 6 (a shift rack 61). The separation control component 7 is composed of a cylindrical cavity 71, a hose, a shift member 8 (a piston rod 1 81) and an extrusion member 9 (a piston rod 2 91, a bonding plate 92, and a return spring 93). When the steel cage is hoisted to a vertical state, the bonding plate 92 contacts the abutment plate 72 and is squeezed. The gas in the fixed cavity 43 is pushed into the cylindrical cavity 71 through the hose, driving the piston rod 1 81 to slide, thereby driving the shift rack 61 to slide downward, and driving the rotating shaft 51 and the clamping plate 12 to rotate through the transmission gear 62. The arc groove on the clamping plate 12 clamps the lower part of the steel cage to keep it stable.

[0057] The two clamping plates 12 rotate outward synchronously, and when they reach a certain angle, they will separate from the steel cage, eliminating the connection between the small hook 11 and the steel cage. The whole process realizes the smooth lifting, clamping and releasing of the steel cage, thereby improving the safety and efficiency of the lifting operation.

[0058] Example 2: Please refer to Fig.10 , the present invention provides a technical solution:

[0059] Different from Example 1, a universal joint 13 is arranged between the piston rod 91 and the fitting plate 92. The universal joint 13 arranged between the piston rod 91 and the fitting plate 92 in the device enables the secondary chain 31 to be close to the abutment plate 72 when the steel cage tends to be vertical, and can better fit the abutment plate 72, which is beneficial to ensure the displacement adjustment of the piston rod 91, and further enhances the flexibility and stability of the device, which helps to reduce the shaking or tilting that may occur during the lifting process, thereby improving construction safety.
