Description

Technical Field

[0001] The utility model relates to the technical field of anti-wear cable bridges, in particular to an anti-wear cable bridge. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type and grid type structures, and are composed of brackets, supports and installation accessories. The cable trays can be erected independently in buildings or laid on various buildings and pipe gallery brackets. They should have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance. All parts need to be galvanized. Usually when installing cable trays, the cable trays are installed first and then the wiring is carried out. However, in many cases, blind threading is required in places that are inconvenient to observe, which can easily get stuck or fail to pass through.

[0003] The utility model with the existing authorization announcement number CN215772388U discloses a high-strength aluminum-based composite cable tray, including a first tray and a second tray, wherein the first tray is located on one side of the second tray, and a rubber connecting joint and an adjustment mechanism are provided between the first tray and the second tray, wherein the adjustment mechanism is located in the middle of the rubber connecting joint.

[0004] By adopting the above technical scheme, the protective pad can play a certain protective effect on the cable when in use, can reduce the wear of the cable when in use, and can fix the cable through the wire clip to avoid the cable from being entangled, and can distinguish cables with different uses. The adjustment mechanism can adjust the direction between the first bridge and the second bridge through the first adjustment arm and the second adjustment arm when in use, and can facilitate the steering installation of the first bridge and the second bridge when in use, which can reduce the use of bridge materials and save resources. The effect of use is better than that of traditional methods. However, the above technical scheme makes it difficult to install the cable in place when it is inconvenient to observe, and it can only be a mess. Long-term contact with the outer shell is prone to damage the protective layer of the cable due to changes in the outer shell temperature, thereby reducing the service life of the cable.

DETAILED DESCRIPTION

[0024] In order to better understand the purpose, structure and function of the utility model, the wear-resistant cable tray of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] See also Figure 1-4 The utility model discloses an anti-wear cable bridge, comprising an outer shell 1 and a partition plate 2. The inner bottom wall of the outer shell 1 is fixedly connected to the bottom surface of the partition plate 2. A hanger 9 is arranged above the outer shell 1. Two hanging holes 10 are provided on the upper surface of the hanger 9. The hanger 9 is hung on the roof or the bottom surface of the bridge by passing the hanging holes 10 with external screws to ensure the stability of the hanger 9.

[0026] Two collecting frames 3 are fixedly connected to the inner bottom wall of the outer shell 1, and the side surfaces of the two collecting frames 3 close to each other are fixedly connected to the left and right side surfaces of the partition board 2. A cross bar 11 is arranged under the hanger 9, and the upper surface of the cross bar 11 contacts the bottom surface of the outer shell 1. The cross bar 11 is used to hold the outer shell 1 to ensure that the outer shell 1 can be windproof and not easy to shake.

[0027] The back of each collecting frame 3 is fixedly connected to a limiting tube 4, and the inner bottom wall of the outer shell 1 is fixedly connected with four limiting frames 5, wherein the upper surfaces of two limiting frames 5 are fixedly connected to the inner top wall of the outer shell 1, and the upper surface of the cross bar 11 is fixedly connected with two limiting plates 12, and the side surfaces of the two limiting plates 12 close to each other are in contact with the left and right side surfaces of the outer shell 1, and the limiting plates 12 are used to limit the outer shell 1, play a role in locating the installation position of the outer shell 1, have an aesthetic effect, and make the installed cable tray both beautiful and safe.

[0028] The upper surfaces of the other two limit frames 5 are fixedly connected to the inner top wall of the partition board 2, four limit pulleys 6 are arranged inside the outer shell 1, the inner wall of the cross bar 11 is threadedly connected to two threaded hangers 13, the outer surface of each threaded hanger 13 is threadedly connected to the inner wall of the hanger 9, and the two threaded hangers 13 are threadedly connected to the cross bar 11 and the hanger 9, so the height of the bridge hoisting can be adjusted according to the actual installation situation to avoid contact with trees, street lights, etc. to cause electrical contact.

[0029] The outer surface of each limiting pulley 6 is fixedly connected to two limiting blocks 7, and each limiting block 7 is slidably connected to the inside of the limiting frame 5. The outer surface of each threaded hanger 13 is threadedly connected to four threaded caps 14, wherein the upper surfaces of two threaded caps 14 are in contact with the bottom surface of the cross bar 11, and the bottom surfaces of the other two threaded caps 14 are in contact with the upper surface of the hanger 9. The design of having two threaded caps 14 at both ends of each threaded hanger 13 can reduce the risk of falling off on the one hand, and can also play a protective role on the other hand.

[0030] The side of each group of limit blocks 7 that are away from each other is fixedly connected with a spring 8, and the end of each spring 8 that is away from the limit block 7 is fixedly connected to the inner top wall or the inner bottom wall of the limit frame 5. Two connecting frames 15 are arranged on the outer side of the outer shell 1, and the sides of the two connecting frames 15 that are close to each other are in contact with the left and right sides of the outer shell 1. Three bolts 16 are arranged on the outer side of each connecting frame 15, and the ends of each group of bolts 16 that are close to each other successively penetrate the connecting frame 15 and the outer shell 1 and extend to the inside of the outer shell 1. The connecting frame 15 is fixed to the outer surface of the outer shell 1 by using the bolts 16. At this time, the connection can be extended indefinitely by using another outer shell 1 to meet the requirements of the expected installation length.

[0031] The bottom surface of the shell 1 is provided with three ventilation holes 17, and a top cover 18 is provided above the shell 1. The bottom surface of the top cover 18 is in contact with the upper surface of the shell 1. The top cover 18 is used for dust and rain protection and decoration. The ventilation holes 17 can be ventilated to avoid the service life of the cable due to excessive temperature under direct sunlight.

[0032] The working principle of the utility model is: first, the hanger 9 is installed on the roof or the bottom of the bridge by using two external screws through the hanging holes 10, and then two threaded hangers 13 are installed on the hanger 9, and the threaded hangers 13 are fixed by installing threaded caps 14, and then the housing 1 is placed between the two threaded hangers 13, and then the cross bar 11 is installed, and the cross bar 11 is fixed again by using two threaded caps 14, and finally the housing 1 is placed between the two limit plates 12 to ensure that the housing 1 is not easily shaken by wind or the like;

[0033] At this time, the partition plate 2 is used to divide the shell 1 into two completely independent spaces, so that two cables can be passed through. The collection frame 3 is equal to the internal size of the shell 1, so that the cable can be blindly inserted without observation, and the cable can be introduced into the two limiting pulleys 6 by using the limiting tube 4. When the cable passes through the two limiting pulleys 6, if the cable is thicker, the two limiting pulleys 6 can be stretched open. At this time, the limiting pulley 6 drives the limiting block 7 to squeeze the spring 8. The two limiting pulleys 6 allow the cable to be suspended in the middle of the shell 1 without touching the inner wall of the shell 1. In addition, the cable can be clamped by the spring 8, which plays a role in indirectly fixing the cable, increasing the distance between the cables at equal distances inside the shell 1. With such a structure, the cable can be hoisted as a whole inside the shell 1 to reduce contact or wear with the shell 1, so that the two limit pulleys 6 can guide the cable during the passage of the cable, and can support the cable when the cable stops passing through, and automatically adjust the size of the gap between the two limit pulleys 6 according to the thickness of the cable. The top cover 18 can be used to block dust and rain for the shell 1, and the design of the air vents 17 can prevent the temperature inside the shell 1 from being too high due to direct sunlight in summer, which affects the service life of the cable. The wear-resistant cable bridge is achieved, and the cable can be directly passed through blindly when it is inconvenient to observe, ensuring that it can be installed in the designated position without getting stuck, thereby extending the service life of the cable.
