The radius of the lower part is much larger than the highest The radius of the place makes the hanging basket unable to continue to descend. For example, it is inconvenient to transport materials for construction and reinforcement with spiders, and the overall construction is difficult. In order to solve the above technical problems, the present invention proposes a construction crane for the reinforcement of hyperbolic structures. Baskets and working methods.

Example 1

The structure of this embodiment is explained by taking a cooling tower as an example, including the hanging basket 1. The telescopic arm 3 and the electromagnet, wherein the telescopic arm 3 is arranged horizontally, one end of the telescopic arm 3 is fixedly arranged on the side of the hanging basket 1, and the other end is fixedly equipped with an electromagnet, and the hanging basket 1 is brought closer by the adsorption of the electromagnet. On the cooling tower wall 9.

The telescopic arm 3 is fixedly arranged on the side of the hanging basket 1, which can adjust the verticality of the hanging basket 1 to ensure construction safety, and can also play a restrictive role on the hanging basket 1, greatly improving the stability of the hanging basket 1 when in use. It effectively avoids shaking of the hanging basket 1 when working at heights.

The hanging basket 1 is provided with a pulley 2, and the pulley 2 cooperates with the traction rope 8 to realize the hoisting of the hanging basket 1, wherein the winch for retracting the traction rope 8 is fixedly arranged on the top of the cooling tower.

The telescopic arm 3 is an electric telescopic arm structure. There are at least two telescopic arms 3. The number of telescopic arms 3 can be two or more. The specific number of settings needs to be selected according to actual needs, and there are not too many here. limit.

Specifically, when there are two telescopic arms 3, the two telescopic arms 3 are horizontally distributed up and down and parallel to each other, so as to realize the adjustment of the verticality of the hanging basket 1 through the different telescopic amounts of the two telescopic arms 3; 3, when there are four, the telescopic arms 3 are horizontally distributed in pairs and parallel to each other.

The setting of the electromagnet can make the hanging basket 1 close to the cooling tower wall 9 without being affected by the curve of the structure. The setting of the telescopic arm 3 can keep the hanging basket 1 in a vertical state at all times by changing its telescopic length, ensuring construction comfort and safety sex.

Specifically, the electromagnet is divided into a first electromagnet 5 and a second electromagnet 6, and one end of the telescopic arm 3 close to the cooling tower wall 9 is fixedly provided with a mounting seat 4, the first electromagnet 5 is fixedly arranged on the mounting seat 4, and the second electromagnet 5 is fixed on the mounting seat 4. Two electromagnets 6 are arranged opposite to the first electromagnet 5 and are positioned at the other side of the cooling tower wall 9, that is, the first electromagnet 5 and the second electromagnet 6 are oppositely arranged on both sides of the cooling tower wall 9, and the first electromagnet The adsorption between the iron 5 and the second electromagnet 6 makes the hanging basket 1 close to the cooling tower wall 9 .

Wherein, the area and the height of the first electromagnet 5 and the second electromagnet 6 (the height here is the height of the first electromagnet 5 and the second electromagnet 6 from the ground) are all the same, so as to ensure the difference between the two as much as possible. In actual use, the strength of the adsorption force of the first electromagnet 5 and the second electromagnet 6 can be controlled by controlling the magnitude of the current, so as to provide sufficient strong adsorption force and adapt to different wall thicknesses.

The first electromagnet 5 and the second electromagnet 6 are respectively provided with a traction rope 8, and the first electromagnet 5 and the second electromagnet 6 are drawn by respective traction rope 8 respectively, and the first electromagnet 5 and the second electromagnet The traction rope 8 on the iron 6 utilizes the winch on the cooling tower top to retract and release equally.

Wherein, the traction rope 8 on the hanging basket 1, the first electromagnet 5, and the second electromagnet 6 is all driven by the same winch, and under the action of the traction rope 8, not only the first electromagnet 5 and the second electromagnet can be The iron 6 moves up and down synchronously with the hanging basket 1, which can also avoid the misalignment of the first electromagnet 5 and the second electromagnet 6 during the movement process, so as to ensure the effective adsorption between the first electromagnet 5 and the second electromagnet 6 , so that the hanging basket 1 can effectively approach the cooling tower wall 9 during the lifting process.

It can be understood that the traction rope 8 on the hanging basket 1, the first electromagnet 5, and the second electromagnet 6 can also use different hoists respectively. At this time, it is necessary to ensure that the hoists work synchronously. 1. The first electromagnet 5 and the second electromagnet 6 can be lifted and lowered synchronously, and there are no too many restrictions here.

Traction rope 8 is made up of steel wire rope and cable wire, and wherein, steel wire rope is used for hanging basket 1, the traction of first electromagnet 5, the second electromagnet 6; The work of two electromagnets 6 provides electric support.

Since the surface of the cooling tower wall 9 is not smooth, in order to reduce the friction between the first electromagnet 5, the second electromagnet 6 and the cooling tower wall 9, the first electromagnet 5 and the second electromagnet 6 are all set Roller 7 is provided to avoid damage to first electromagnet 5 and second electromagnet 6 due to friction.

Specifically, the roller 7 is rotated and arranged on the side of the first electromagnet 5 and the second electromagnet 6 close to the cooling tower wall 9, so as to reduce the friction between the first electromagnet 5, the second electromagnet 6 and the cooling tower wall 9 by the roller 7. friction.

It should be noted that the roller 7 needs to use a one-way wheel structure, the direction of travel is the height direction of the structure, and the universal wheel structure cannot be used, so as to avoid the problem caused by the universal wheel during the lifting process of the first electromagnet 5 and the second electromagnet 6. The relative position deflection occurs due to the rotation.

It can be understood that the start and stop control of the hoist can be controlled by the operator in the hanging basket 1. At this time, a remote control device is required, and a cooperative operator can also be reserved at the top of the tower. Similarly, the telescopic arm 3, the electromagnet The same is true for the control, and the specific control method can be selected according to actual needs, and there are no too many restrictions here.

Through the setting of the telescopic arm 3, the first electromagnet 5, and the second electromagnet 6, the hanging basket 1 can be close to the structure in a vertical state without being affected by the curve of the structure, which effectively solves the difficulty of scaffolding and the spider man. The problems of small operating surface, dangerous construction and inability to construct the hanging basket have greatly improved work efficiency.

Shuttle for multi-span jobs.

It should be noted that when performing multi-span operations, it is necessary to ensure that the adjacent hanging baskets 2 are at the same height.
