Description

Technical Field

[0001] The utility model relates to the field of cable brackets, in particular to a movable cable bracket in a caisson. Background Art

[0002] With the advancement and expansion of urbanization, more and more high-voltage power tunnels and integrated pipelines are being built and planned, and the demand for cable supports is also increasing.

[0003] However, due to the influence of existing pipelines, underground structures and geology in the city, the design and construction of power tunnels and integrated pipeline corridors require the use of trenchless jacking tunnels. However, jacking tunnels require the construction of caissons before they can be used for shield machine implementation. However, when the caissons are connected to the boundary between the open-cut tunnel and the jacking tunnel, there will be a large change in the height difference angle of the channels on both sides, and the connection angle will change greatly, which is not conducive to the laying and fixing of cables.

[0004] In the currently commonly used caisson solutions, most cables are only supported by cable brackets, but they cannot be well fixed. They are even restricted by height differences and space issues, and the cables are in a free stress state.

[0005] Therefore, we propose a movable cable bracket that can adapt to a large number of caissons and can cope with various height differences and angles. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a movable cable bracket in a caisson to solve the technical problem that in the current commonly used caisson scheme, most cables are only supported by cable brackets but cannot be well fixed, and are even restricted by height differences and space problems, leaving the cables in a free stress state.

[0007] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: to design a movable cable bracket in a caisson, including a connecting steel pipe column, the connecting steel pipe column is installed with a clamp, a square steel crossarm connecting plate is installed on one side of the clamp, and a square steel crossarm is installed on one side of the square steel crossarm connecting plate.

[0008] Preferably, a connection plate A and a connection plate B are respectively welded on the inner side of the square steel cross arm after being cut.

[0009] Preferably, the connecting plate A and the connecting plate B are connected by bolts.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model can effectively adapt to various height differences and cross-angle channels in the caisson. Only through structural optimization, it can be more conducive to the fixation of power cables without increasing costs, thereby improving the operating safety of power cables.

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0019] Example 1: A movable cable support in a caisson, see Figures 1 to 5 , including a connecting steel pipe column 1, the connecting steel pipe column 1 is installed with a clamp 7, a square steel cross arm connecting plate 2 is installed on one side of the clamp 7, and a square steel cross arm 3 is installed on one side of the square steel cross arm connecting plate 2.

[0020] For details, see Figure 3 , the square steel cross arm 3 is cut and a connecting plate A4 and a connecting plate B5 are welded on the inner side.

[0021] For further information, see Figures 3 to 5 The connecting plate A4 and the connecting plate B5 are connected by bolts 6.

[0022] When using a movable cable support in a caisson, according to the commonly used and popular steel pipe column form in the current caisson, a clamp 7 is used to connect with the steel pipe column, and then the square steel cross arm 3 is connected through the square steel cross arm connecting plate 7.

[0023] This patent adds connecting plates A4 and B4 to the rectangular tube of the cable support, and realizes the rotatable fixation of the inner and outer plates through the opening of the plates, so as to realize the 360-degree rotatable angle in a vertical manner. Compared with the current common caisson support solution with ±25 degrees of adjustment, it has a greater range of improvement.

[0024] By combining with the clamp and the column, 360-degree rotation on the horizontal plane can be guaranteed.
