Description
Technical Field
The utility model belongs to the technical field of tower crane, a tower crane double tower body is related to.
Background
At present, tower cranes are widely applied to construction projects such as industrial plants, civil buildings, nuclear power, thermal power, bridges and the like. High safety engineering construction (such as nuclear power construction) and high free height engineering (such as operation but not attachment of stadiums and large theatre group towers) are gradually increased. The rated height of the tower crane in the non-attachment state is called the free height for short, and the free heights of tower cranes with different grades and models are also different. How to safely and reliably solve the problems on the basis of less increased cost is a development direction of tower crane application technology. Due to the complicated site conditions of the construction project, some situations are quite special, such as: in order to avoid existing buildings, trees, high-voltage lines and the like, the initial installation height of the tower crane must exceed the height of an obstacle, but the buildings are not constructed to a certain height at the moment, and attachment points cannot be arranged on the buildings to enhance the stability of the tower crane. Some building projects are tower group operation, a certain safety distance is required to be ensured between tower cranes, and some tower cranes must avoid adjacent tower cranes, so that the tower cranes with high free height are required to complete the work, and the conventional methods for increasing the free height of the tower cranes comprise the following steps: 1. a mode 2 of a large-size standard section, a conversion section and a small-size standard section is adopted, and the whole tower body adopts the large-size standard section. Both of these forms are costly to manufacture, install and transport. Especially, the cost is greatly increased under the condition that a user carries out transformation on the existing tower crane. Meanwhile, in view of the fact that the strength and rigidity of the tower body are the main reasons influencing the increase of the height of the tower crane, the maximum free height of the tower crane can be improved only by increasing the strength and rigidity of the tower body, and the two modes only increase the height of the tower body, so that the tower crane cannot reach the maximum free height due to the fact that the strength and rigidity of the tower body cannot be further enhanced, and actual working requirements are difficult to meet.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, design are ingenious, can effectively overcome the tower crane double tower body that current increase tower crane free height mode weak point.
The utility model adopts the technical proposal that: this two towers include that the lower extreme passes through the interior tower body of interior tower body lower margin fixed on the basis, and its characteristics are: the outer tower body is sleeved outside the inner tower body, the lower end of the outer tower body is fixed on the foundation through outer tower body ground feet, and the upper end of the outer tower body is provided with an attachment section connected with the inner tower body.
The utility model discloses an increase the outer body of tower that bending resistance is stronger in the outside of body of tower including, connect into an organic whole through adhering to the festival and form two body of tower structures, part the atress transmission route of body of tower, the main transmission tower machine moment of tumbling of body of tower promptly, the main vertical power of transmission tower machine of interior body of tower, and then alleviate the atress of former single body of tower, increase whole body of tower bearing capacity, the intensity and the rigidity of whole body of tower have been improved greatly, thereby improve tower crane's the biggest free height, in order to satisfy the actual work requirement. The utility model discloses simple structure, design are ingenious, have not only improved the biggest free height of tower body, but also improved the anti typhoon ability and the rate of equipment utilization of tower machine, have filled the blank of this type of tower body, are worth extensive popularization and application.

Detailed Description
As shown in figure 1, the utility model comprises an inner tower 6 whose lower end is fixed on the foundation through an inner tower foot 5. The outer tower body 2 is sleeved outside the inner tower body 6, the lower end of the outer tower body 2 is fixed on the foundation through an outer tower body foot 4, and the upper end of the outer tower body is provided with an attachment section 1, the inner side of which is connected with the inner tower body 6.
As shown in fig. 1 and 2, an adjusting joint 3 is provided between the lower end of the outer tower 2 and the outer tower anchor 4, and the adjusting joint 3 is used for adjusting the height of the outer tower 2, thereby ensuring that the attachment joint 1 is installed at the horizontal web member of the inner tower 6. The upper end and the lower end of the outer tower body 2 are respectively connected with the upper ends of the attachment section 1 and the adjusting section 3 through bolts 12. The lower end of the adjusting joint 3 is connected with an outer tower body anchor 4. As shown in fig. 3, 4 and 5, the attachment section 1, the outer tower body 2 and the adjustment section 3 are all H-shaped main limbs, 6 bolt holes are arranged on the upper end surface and the lower end surface of each main limb for connecting with each other, and the adjustment section 3 is of an integral welding structure.
As shown in fig. 3, 6, 7 and 8, the attachment joint 1 is formed by connecting two half frames 7 by a first bolt 10 in the middle.
