Abstract

The present invention discloses a climbing cage structure of a tower crane, comprising: a hollow frame structure, which is slidably mounted on a tower body; a lifting arm, which is connected to the hollow frame structure; and a balancing arm, which is connected to the hollow frame structure. The extension direction of the balancing arm is opposite to the extension direction of the lifting arm, and a plurality of counterweights are arranged on one end of the balancing arm different from the hollow frame structure. The bottom end of the tower body of the present invention is connected to a slewing base, which can drive the tower body and the hollow frame to rotate synchronously, and the hollow frame can slide on the tower body to change its height position. When performing assembly operations, the hollow frame can be displaced to a position close to the ground for assembly, thereby greatly reducing the difficulty and danger of the assembly work, and can also improve the efficiency of the assembly operation.

Tower crane is a kind of heavy machinery that increases with the increase of building height, and known tower crane 10 is shown in Figure 1, and this tower crane 10 mainly comprises a relatively rotatable upper connecting plate 11 and lower connecting plate 12 The lifting arm 13 for hanging, the balance arm 14 and the tower body 15 for supporting are respectively connected, and a climbing cage 16 is set on the top of the tower body 15, and the tower body 15 is heightened by lifting the climbing cage 16 Operation. When the jib 13 carries out lifting work, it is realized by the upper connection plate 11 and the lower connection plate 12 of the relative rotation, and all components connected to the upper connection plate 11 are rotated synchronously. Components are all positioned at the top of the tower body 15, so when assembling, they must be operated at high altitudes, and the operation is difficult and extremely dangerous.

Contents of the invention

The technical problem to be solved by the present invention is to provide a climbing cage structure of a tower crane, which can solve the problem that the lifting arm and the balance arm are fixed on the top of the tower body and need high-altitude operations.

In order to solve the above-mentioned technical problems, the present invention provides a climbing cage structure of a tower crane, which is sleeved on a tower body, and the bottom end of the tower body is fixedly connected to a rotary base, and the rotary base drives the tower body and the climbing cage structure. The cage structure rotates synchronously; the climbing cage structure includes:

A hollow frame structure is slidably sleeved on the tower body;

a boom connected to the hollow frame structure; and

A balance arm is connected to the hollow frame structure, and the extension direction of the balance arm is opposite to the extension direction of the lifting arm, and a plurality of counterweights are arranged at the end of the balance arm different from the hollow frame structure.

In the present invention, the lifting arm and the balance arm are assembled on the hollow frame structure, and the hollow frame structure can be slidably sleeved on the tower body to carry out the lifting action, and can be rotated synchronously with the tower body by the rotating base. During vertical operation, the climbing cage structure can be slid to a position close to the ground for assembly operation, which reduces the difficulty and danger of work, thereby improving the efficiency of assembly operation.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

A preferred embodiment of the climbing cage structure of the tower crane of the present invention is shown in Figures 2 to 5, the climbing cage structure is slidably sleeved on a tower body 20, and the bottom end of the tower body 20 is fixedly connected to a rotating On the base 30, the rotating base 30 drives the tower body 20 and the climbing cage structure to rotate synchronously. The climbing cage structure includes:

A hollow frame structure 40 is slidably sleeved on the tower body 20, the hollow frame structure 40 has a first workbench 41 and a second workbench 42, the first workbench 41 and the second workbench 42 are respectively arranged around the hollow frame structure 40, and the first workbench 41 and the second workbench 42 can be used for the erection personnel to stand;

A boom 50 is connected to the first working platform 41 of the hollow frame structure 40;

A balance arm 60 is connected to the second workbench 42 of the hollow frame structure 40, and the extension direction of the balance arm 60 is opposite to the extension direction of the boom 50. The balance arm 60 is different from one end of the second workbench 42 A plurality of counterweights 61 are set, and the number of counterweights 61 can be changed to balance counterweights with the boom 50 when the boom 50 hangs heavy objects; and

An operating unit 70 is fixedly connected to the boom 50, and the operating unit 70 has an operating room 71 for carrying an operator.

The above is the structural relationship of the climbing cage structure of the tower crane of the present invention. During use, the hollow frame structure 40 of the climbing cage structure can be sleeved on the tower body 20 first, and the hollow frame structure 40 is slid to the bottom of the tower body 20, so that The hollow frame structure 40 is located at the position closest to the ground, as shown in Figure 2. At this time, the assembly operation of the lifting arm 50, the balance arm 60 and the operating unit 70 can be carried out, and the work does not need to be carried out at a high altitude, which can greatly reduce the work load. Difficulty and danger of work, and the efficiency of assembly can be greatly improved due to the reduction of work difficulty. In addition, when the operating unit 70 is assembled, the operating compartment 71 is located close to the ground, and the operator can enter the operating compartment 71 of the operating unit 70 at a lower position, and can enter the operating compartment without using a crane or other hanging devices. Room 71. After the climbing cage structure is assembled, the whole climbing cage structure slides upward on the tower body 20, then the climbing cage structure can take off and land synchronously as a whole, and the hollow frame structure 40, the boom 50, the balance arm 60 and the The operating unit 70 rises, as shown in FIG. 4 , and can perform hanging work.

The climbing cage structure of the present invention is sleeved on the tower body 20, and the tower body 20 is fixedly connected to the rotatable slewing base 30, so when the lifting arm 50 is to be hung and the position of the lifting arm 50 must be changed When the rotating base 30 is controlled to rotate, then the rotating base 30 can drive the tower body 20 to rotate, and the whole climbing cage structure sleeved on the tower body 20 also rotates synchronously, thereby making the hollow frame structure 40 of the climbing cage structure, lifting The arm 50 , the balance arm 60 and the operating unit 70 rotate synchronously to achieve the purpose of changing the position of the lifting arm 50 .
