Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a bridge frame which is convenient for maintenance. Background Art

[0002] Cable trays, as carriers for laying various cables, are widely used in petrochemical, metallurgy, electric power, schools, hospitals, communications, high-rise buildings and other fields.

[0003] Most of the bridge cover plates on the market are a whole plate. When the bridge needs to be repaired, the whole cover plate often needs to be removed. The removed cover plate takes up a considerable placement space. Especially when the bridge is of considerable height, the up and down transportation and installation of the cover plate is time-consuming and laborious, affecting the efficiency of maintenance. There are also a few structural designs on the market that temporarily fix the whole cover plate after flipping it over, but the placement of the whole cover plate at an angle facing the air is more or less dangerous. Once structural defects occur after long-term use, it is very easy to cause safety accidents. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention aims to provide a bridge frame which is highly safe and convenient for temporary maintenance.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A bridge frame convenient for maintenance comprises a U-shaped shell for placing cables and a cover plate for sealing the shell, wherein the cover plate comprises two crossbeams, a left panel, a middle panel and a right panel; the two crossbeams are located near the front and rear ends, and a wall groove for pressing the crossbeams is provided at the corresponding positions of the shell side walls; three panels are arranged in sequence on the crossbeams, and the three panels are rotatably connected by a rotating shaft; the left panel is fixedly connected to the crossbeam, the middle panel and the right panel are overlapped with the crossbeam, and the right end face of the right panel and the crossbeam is provided with a cylindrical connecting hole corresponding to the position, and the fixed connection is achieved by inserting the two arms of a "concave"-shaped rubber connector into the connecting hole; the left side face of the left panel and the right side face of the right panel are provided with a plug plate protruding outward and extending vertically downward at the position located between the two crossbeams, and a slot is provided at the corresponding position of the shell; the slot is composed of a shell side plate, a first slot plate vertically led outward from the shell side plate, and a second slot plate vertically led upward from the outer edge of the first slot plate; the outer side face of the plug plate and the inner side face of the second slot plate are mutually matching wavy curved surfaces.

[0007] Preferably, the top end of the second slot plate is vertically led outward to the third slot plate, and the left panel and the right panel are extended at corresponding positions so as to overlap with the third slot plate.

[0008] Preferably: a supporting plate extending vertically upward is provided in the middle of the left panel.

[0009] Preferably, the support plate is located on the right side of the center line of the left panel, and the line connecting the top surface and the right edge of the left panel is 120 degrees to the horizontal direction.

[0010] Preferably, the left panel, the middle panel and the right panel are sealed at the connection of the rotating shaft by an elastic sealing member, and the elastic sealing member is elastic rubber.

[0011] Preferably: the upper edge of the inner side surface of the support plate is rotatably connected to the magnetic adsorption plate, and the magnetic adsorption plate is fixedly connected to the inner side surface of the support plate through an elastic connecting piece, and the middle panel and the right panel are embedded with ferromagnetic adsorption parts corresponding to the crimping surface of the magnetic adsorption plate after rotation.

[0012] The bridge frame that is easy to maintain provided by the present invention mainly optimizes and improves the structure of the bridge frame cover plate itself and the connection structure with the shell, and brings numerous beneficial effects, which are as follows: 1. The cover plate is composed of a covering surface of three plates and two cross beams at the bottom. In the connection with the shell, the front and rear positioning is first achieved by the cross beams and the shell wall grooves, and then the left and right positioning is achieved by plugging the plug-in plates on both sides of the left panel and the right panel. The wavy surface of the plug-in surface makes the cover plate have a very stable structure after the overall insertion. 2. Among the three panels, the left panel is fixedly connected to the crossbeam, while the middle panel and the right panel are directly overlapped. The panels are connected by a rotating shaft, and the right side of the right panel is fixed to the crossbeam by a "concave"-shaped rubber connector. When maintenance is required, pull out the "concave"-shaped rubber connector, rotate the right panel and the middle panel to the left in turn until the two panels are overlapped on the support plate. At this time, two-thirds of the panel space of the cover plate is exposed, which fully meets the maintenance conditions. The support plate is located on the left panel and thus has a stable support surface, while the flipped middle panel and right panel are not only supported by the support plate, but also have the left panel as the foundation below, which has high safety (because the left panel is fixedly connected to the crossbeam, and the left panel is connected to the middle panel by a rotating shaft, so when the support plate fails, there is no danger of the panel falling outward). 3. The third slot plate added on the outside of the slot increases the overlap area of ​​the cover plate after being plugged in with the shell, reduces the pressure strength of linear plugging, reduces deformation that may be caused by long-term use, and increases service life.

DETAILED DESCRIPTION

[0020] The bridge structure disclosed in the present invention is now fully described in conjunction with specific embodiments so that ordinary technicians in the field can understand and implement it. The words about orientation described in the text are based on the given drawings and are not limitations on the technical solution itself.

[0021] Example 1

[0022] like Figure 1-Figure 4 As shown, the present invention discloses a bridge frame that is easy to repair, including a "U"-shaped shell 2 for placing cables, and a cover plate 1 (made of aluminum alloy) that seals the upper opening of the shell 2, wherein the shell 2 can be an integrally manufactured shell, or can be formed by combining multiple plates; the cover plate 1 includes two crossbeams 14, a left panel 11, a middle panel 12 and a right panel 13; the two crossbeams 14 are located near the front and rear ends, and corresponding positions on the side walls of the shell 2 are provided with wall grooves 25 for the crossbeams 14 to be pressed into; the three panels are arranged in sequence on the crossbeam 14, and the three panels are rotatably connected by a rotating shaft 15; the left panel 11 is fixedly connected to the crossbeam 14, and the middle panel 12 is fixedly connected to the right panel 13; The right panel 13 and the cross beam 14 are overlapped, and the right side end faces of the right panel 13 and the cross beam 14 are provided with corresponding cylindrical connecting holes, and the two arms of the "concave"-shaped rubber connector 16 are inserted into the connecting holes to achieve fixed connection; the left side face of the left panel 11 and the right side face of the right panel 13 are provided with a plug plate 17 that convexes and extends vertically downward in the middle, and a slot is provided at the corresponding position of the shell 2; the slot is composed of a side plate 24 of the shell 2, a first slot plate 21 vertically extended outward from the side plate 24, and a second slot plate 22 vertically extended upward from the outer edge of the first slot plate 21; the outer side surface of the plug plate 17 and the inner side surface of the second slot plate 22 are wavy surfaces that match each other.

[0023] Through the above structural design, the basic improvement of the bridge frame is achieved. When installing the cover plate 1, the middle panel 12 and the right panel 13 are arranged in sequence, placed on the crossbeam 14, and the right panel 13 is fixed to the crossbeam 14 through the rubber connector 16, and then the whole cover plate 1 is plugged into the shell 2 through the plug-in plates 17 on both sides; the wave surface design (elastic extrusion) of the plug-in surface is used to make the plug-in have a stable structure. During maintenance, the rubber connector 16 is pulled out, and then the plug-in plate 17 on the outside of the right panel 13 is slightly lifted upward. At this time, the right panel 13 is in a free state and flipped to the left along the rotating shaft 15, which can be divided into flipping the right panel 13 alone and flipping the middle panel 12 and the right panel 13 continuously. Flipping the right panel 13 alone can quickly check whether it needs maintenance. After the problem is found, the double panels (middle panel 12, right panel 13) are flipped. At this time, two-thirds of the cover plate 1 is opened, which fully meets the maintenance effect. In order to restore the cover plate 1 well after the maintenance is completed, preferably: a vertical support plate 18 is provided in the middle of the left panel 11. The middle panel 12 and the right panel 13 are pressed on the support plate 18 after being turned over, so there is a good support angle, which is also convenient for the operation during restoration. Preferably: the support plate 18 is located on the right side of the center line of the left panel 11.

[0024] From the above, it can be seen that during maintenance, the opened panel is placed on the left panel 11 and is constrained by the rotating shaft 15 on the right side, so the stability is extremely good, the panel will not slip, and there is no need to remove the entire panel, which improves the convenience of maintenance.

[0025] Preferably, the third slot plate 23 is vertically led outward from the top end of the second slot plate 22, and the left panel 11 and the right panel 13 are extended at corresponding positions so as to overlap with the third slot plate 23. Through the design of the third slot plate 23, the pressure covering area of ​​the plug-in joint is greatly increased, the linear connection of the traditional plug-in joint is avoided, the linear pressure is reduced, and deformation will not occur during long-term use.

[0026] Preferably, the left panel 11, the middle panel 12, and the right panel 13 are sealed at the connection of the rotating shaft 15 by an elastic seal 19, and the elastic seal 19 is elastic rubber.

[0027] Example 2

[0028] like Figure 5 , Figure 6As shown; this embodiment makes the following improvements on the basis of embodiment 1: the upper edge of the inner side surface of the support plate 18 is rotatably connected to the magnetic adsorption plate 181, and the magnetic adsorption plate 181 is fixedly connected to the inner side surface of the support plate 18 through an elastic connector 183, and the middle panel 12 and the right panel 13 are embedded with ferromagnetic adsorption parts 182 at the corresponding positions of the crimping surfaces of the magnetic adsorption plate 181 after rotation. Through the design of the magnetic adsorption plate 181 and the ferromagnetic adsorption part 182, the middle panel 12 and the right panel 13 are in a stable fixed state after flipping, and the rotation connection mode of the elastic connector 183 and the magnetic adsorption plate 181 allows the magnetic adsorption plate 181 to adjust the adsorption according to the flipping angle, which is flexible and changeable.

[0029] The above embodiments are only preferred embodiments of the present invention and are not any formal limitations on the present invention. Any technician familiar with the art can use the above disclosed methods to make many possible changes and modifications to the technical solution of the present invention without departing from the technical principle and solution scope of the present invention, or modify it into an equivalent embodiment of equivalent changes.
