Description

Technical Field

[0001] The utility model relates to the field of bus duct mounting brackets, and more specifically to a bus duct mounting bracket with a reliable and stable structure. Background Art

[0002] A through opening is usually provided at the corner of the bottom of the water and electricity well in the unit building for the later installation of the bus duct so that the bus duct can extend vertically up and down to the water and electricity wells on each floor. A bus duct installation bracket is usually installed between the bus duct and the through opening to install the bus duct inside the through opening in contact with the ground of the water and electricity well.

[0003] Although a redundant structure for buffering the up and down movement of the bus duct holder is provided inside the existing bus duct installation bracket, the extended through nails are directly connected to the circular through hole one or the circular through hole two, and the connection structure is relatively simple, which cannot meet the deflection of the extended through nails in the front, back, left and right directions inside the circular through hole one or the circular through hole two, so that the offset buffer redundancy of the bus duct holder on a group of U-shaped channel steels is limited, which is not conducive to the reliability of the bus duct in adapting to multi-directional structural deformation after installation. Therefore, we propose a bus duct installation bracket with reliable and stable structure to solve the above-mentioned problems. Utility Model Content

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 4 , a bus duct mounting bracket with reliable and stable structure, comprising a group of bus duct holders 1, a group of bus duct holders 1 having the same structure and arranged in mutually opposite directions, and a group of bus duct holders 1 are fixedly installed by screws;

[0027] A group of U-shaped channel steels 2 with the same structure are arranged at the bottom of a group of bus duct holders 1, a group of circular through holes 201 are arranged at the top of a group of U-shaped channel steels 2, a group of strip bolt holes 202 are arranged at the bottom of a group of U-shaped channel steels 2, a group of circular through holes 101 are arranged on the bus duct holder 1 corresponding to the position of the group of circular through holes 201, the circular through holes 201 and the circular through holes 101 are fixedly clamped with rubber washers 3 with the same structure inside, and the corresponding two rubber washers 3 are connected by an extended through nail 4, the end of the top of the extended through nail 4 is fixedly connected with a nut part, the extended through nail 4 located at the bottom of the nut part is sleeved with an upper clamping cap 5, the bottom end of the extended through nail 4 is provided with an external thread structure, and the bottom end of the extended through nail 4 is threadedly connected with a locking nut, the extended through nail 4 located at the top of the locking nut is sleeved with a lower clamping cap 6, and the upper clamping cap 5 and the lower clamping cap 6 have the same structure;

[0028] A support spring 1 7 is sleeved on the outer side of the extended through nail 4 located between the upper clamping cap 5 and the bus duct clamping seat 1, and the top and bottom of the support spring 1 7 are respectively in contact with the bottom of the inner wall of the upper clamping cap 5 and the outer side of the top of the circular through hole 1 201; a support spring 2 8 is sleeved on the outer side of the extended through nail 4 located between the bus duct clamping seat 1 and the U-shaped channel steel 2, and the top and bottom of the support spring 28 are respectively in contact with the outer sides of the circular through hole 1 201 and the circular through hole 2 101; a support spring 3 9 is sleeved on the outer side of the extended through nail 4 located between the U-shaped channel steel 2 and the lower clamping cap 6, and the top and bottom of the support spring 3 9 are respectively in contact with the outer side of the circular through hole 2 101 and the bottom of the inner wall of the lower clamping cap 6.

[0029] The operating principle of this reliable and stable bus duct mounting bracket is:

[0030] First, a set of U-shaped channel steels 2 are installed on both sides of the through opening at the bottom of the hydropower well through expansion bolts, and then the bus duct is inserted into the through opening, and then a set of bus duct holders 1 are installed on both sides of the bus duct at the top of the through opening. At this time, the rubber gaskets 3 inside the circular through hole 2 101 and the circular through hole 1 201 are connected in sequence by using the extended through nails 4, and at the same time, the upper clamping cap 5, the lower clamping cap 6, the support spring 1 7, the support spring 2 8 and the support spring 3 9 are connected, and finally the nut at the bottom of the extended through nail 4 is locked, thereby completing the installation of various components at the connection;

[0031] When the bus duct is subjected to tension in the up and down directions, the tension is first transmitted to a group of bus duct holders 1. At this time, the support spring 1 7, support spring 2 8 and support spring 3 9 located between the bus duct holder 1 and the U-shaped channel steel 2 play a supporting and buffering role, thereby realizing the redundancy of the buffering amount in the longitudinal direction of the connection; when the bus duct is subjected to deflection tension in the front and back or left and right directions, the tension is first transmitted to a group of bus duct holders 1. At this time, the rubber gasket 3 at the connection first makes the deflection amount of the extended nail 4 redundant, and then the support spring 1 7, support spring 2 8 and support spring 3 9 located between the bus duct holder 1 and the U-shaped channel steel 2 play a supporting and buffering role, thereby realizing the redundancy of the buffering amount in the front and back or left and right directions of the connection.

[0032] Embodiment 2:

[0033] In view of the above embodiment 1, for further description, refer to Figure 2 and Figure 3 The inner wall diameters of support spring 1 7 , support spring 2 8 and support spring 3 9 are all the same, the inner wall diameters of circular through hole 1 201 and circular through hole 2 101 are all the same, and the inner wall diameter of support spring 1 7 is larger than the inner wall diameter of circular through hole 1 201 .

[0034] By virtue of the structural form in which the inner wall diameter of the above-mentioned hole is smaller than the inner wall diameter of the corresponding spring, the end of the spring can be placed on the outer edge of the hole, thereby avoiding interference with the installation of the spring.

[0035] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
