A self-lifting cable bracket and cable trench

Abstract

The utility model discloses an autonomously lifting cable support and cable trench, comprising: a vertical support rod, which is arranged in a vertical direction and on which a lifting slide is arranged in a vertical direction; a horizontal support rod, which is movably installed in the vertical support rod through the lifting slide; and a plurality of horizontal support rods, with elastic support members arranged between adjacent horizontal support rods. In the present application, elastic support members are arranged between adjacent horizontal support rods. Due to the elastic support force of the elastic support members, the distance between adjacent horizontal support rods is larger when no cables are installed, so as to form an operating space between two adjacent horizontal support rods, thereby facilitating the laying of cables. When the laying of cables is completed, due to the weight of the cables falling on the horizontal support rods, the pressure on the elastic support members increases and is compressed, thereby causing the horizontal support rods to move downward to reduce the overall center of gravity and the torque generated by the horizontal support rods on the vertical support rods.

Description

Technical Field

[0001] The present application relates to the field of electric power technology, and in particular to an autonomously lifting cable bracket and a cable trench. Background Art

[0002] The cable trench is an underground pipeline used for laying and replacing power cable facilities. It is also the enclosure structure for the laid cable facilities. There are rectangular, circular, arched and other pipeline structural forms.

[0003] Cable trenches are suitable for areas such as roads, factory areas, buildings where cable outlets are concentrated and no electric bypass tunnels are required; urban pedestrian walkways or green spaces, etc.

[0004] Since the space of the cable trench is limited, in order to lay more cables, the spacing between the upper and lower layers of the cable support is usually set smaller, and the smaller upper and lower spacing will bring operational difficulties to the laying of cables. Utility Model Content

[0005] The purpose of the embodiments of the utility model is to provide an autonomously lifting cable bracket and cable trench, which can automatically lower the inter-layer height after the cables are installed, saving space and facilitating cable laying operations.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In one aspect, a self-elevating cable support is provided, comprising:

[0008] A vertical support rod is arranged in a vertical direction, and a lifting slide is arranged on the vertical support rod;

[0009] A horizontal support rod, movably mounted in the vertical support rod via the lifting slide;

[0010] There are multiple horizontal support rods, and elastic support members are arranged between adjacent horizontal support rods.

[0011] As a preferred technical solution of the self-lifting cable bracket, the horizontal support rod has a support rod connecting end connected to the vertical support rod and a support rod extending end away from the vertical support rod, and a guide slider is provided in the support rod connecting end, and the horizontal support rod is installed on the vertical support rod through the guide slider.

[0012] As a preferred technical solution of the autonomous lifting cable support, the guide slider is a cross-shaped structure, and the shape of the lifting slideway matches the guide slider.

[0013] As a preferred technical solution of the autonomous lifting cable support, the guide slider is a T-shaped structure, and the shape of the lifting slide matches the guide slider.

[0014] As a preferred technical solution of the autonomous lifting cable support, the guide slider is an I-shaped structure, and the shape of the lifting slide matches the guide slider.

[0015] As a preferred technical solution of the autonomous lifting cable bracket, a support block is further provided on the vertical support rod and between the two horizontal support rods, and one end of the elastic support member abuts against the guide slider, and the other end abuts against the support block.

[0016] As a preferred technical solution of the self-lifting cable support, the distance between the support block and the upper surface of the lower horizontal support rod is 3-5 times the diameter of the cable to be installed.

[0017] As a preferred technical solution of the autonomous lifting cable support, the elastic support member is a spring.

[0018] As a preferred technical solution of the autonomous lifting cable bracket, a mounting opening is provided on one side of the vertical support rod, and the support block and the elastic support member are both installed in the lifting slide at the mounting opening.

[0019] On the other hand, the present application also provides a cable trench having the self-lifting cable support as described above.

[0020] The beneficial effects of the present application are as follows: in the present application, an elastic support member is arranged between adjacent horizontal support rods. Due to the elastic supporting force of the elastic support member, the distance between adjacent horizontal support rods is larger when the cables are not installed, so as to form an operating space between two adjacent horizontal support rods, thereby facilitating the laying of cables. When the cables are laid, the weight of the cables falls on the horizontal support rods, and the pressure on the elastic support member increases and is compressed, thereby causing the horizontal support rod to move downward to lower the overall center of gravity and the torque generated by the horizontal support rod on the vertical support rod, thereby reducing the locking force pressure of the vertical support rod connected to the wall and reducing the occupation of the height space.

[0035] The cable trench is an underground pipeline used for laying and replacing power cable facilities. It is also the enclosure structure for the laid cable facilities. There are rectangular, circular, arched and other pipeline structural forms.

[0036] Cable trenches are suitable for areas such as roads, factory areas, buildings where cable outlets are concentrated and no electric bypass tunnels are required; urban pedestrian walkways or green spaces, etc.

[0037] Reference Figure 1-5 As shown, an embodiment of the present application provides an autonomously lifting cable bracket, comprising:

[0038] A vertical support rod 100 is arranged in a vertical direction, and a lifting slide 110 is arranged on the vertical direction;

[0039] A horizontal support rod 200 is movably mounted in the vertical support rod 100 via the lifting slide 110;

[0040] There are multiple horizontal support rods 200 , and elastic support members 300 are disposed between adjacent horizontal support rods 200 .

[0041] In the present application, an elastic support member 300 is arranged between adjacent horizontal support rods 200. Due to the elastic support force of the elastic support member 300, the distance between adjacent horizontal support rods 200 is larger when the cables are not installed, so as to form an operating space between two adjacent horizontal support rods 200, thereby facilitating the laying of cables. When the cables are laid, the weight of the cables falls on the horizontal support rod 200, and the pressure on the elastic support member 300 increases and is compressed, thereby causing the horizontal support rod 200 to move downward, lowering the overall center of gravity and the torque generated by the horizontal support rod 200 on the vertical support rod 100, reducing the locking force pressure of the vertical support rod 100 connected to the wall, and reducing the occupation of the height space.

[0042] Specifically, the horizontal support rod 200 in the embodiment of the present application has a support rod connecting end connected to the vertical support rod 100 and a support rod extending end away from the vertical support rod 100, and a guide slider 210 is provided in the support rod connecting end, and the horizontal support rod 200 is installed on the vertical support rod 100 through the guide slider 210.

[0043] In an optional embodiment of the present application, the guide slider 210 is a cross-shaped structure, and the shape of the lifting slide 110 matches the guide slider 210 .

[0044] It should be pointed out that the cross-shaped structure of the guide slider 210 is not a limitation to the present solution, and guide sliders 210 with other structures may also be used in other embodiments.

[0046] The guide slider 210 may also be an I-shaped structure, and the shape of the lifting slide 110 matches the guide slider 210 .

[0047] Reference Figure 4 , 5 As shown, a support block 400 is further provided on the vertical support rod 100 and between the two horizontal support rods 200 , and one end of the elastic support member 300 abuts against the guide slider 210 , and the other end abuts against the support block 400 .

[0048] The support block 400 is used to support the elastic support member 300 , and further to support the upper horizontal support rod 200 .

[0049] The support block 400 is provided with a first limiting groove 410 , the horizontal support rod 200 is provided with a second limiting groove 220 , and both ends of the elastic support member 300 are respectively clamped in the first limiting groove 410 and the second limiting groove 220 .

[0050] The distance between the support block 400 and the upper surface of the horizontal support rod 200 below is 3-5 times the diameter of the cable to be installed.

[0051] Preferably, the distance between the support block 400 and the upper surface of the horizontal support rod 200 below is 4 times the diameter of the cable to be installed.

[0052] Preferably, the elastic support member 300 is a spring. It is understandable that the elastic support member 300 being a spring is not a limitation of the present invention, and other elastic structures can be used as the elastic support member 300 in other embodiments, and those skilled in the art can make a reasonable choice according to actual needs.

[0053] The embodiment of the present application also provides an installation structure of a support block 400 and an elastic support member 300, wherein a mounting opening 500 is provided on one side of the vertical support rod 100, and the support block 400 and the elastic support member 300 are both installed in the lifting slide 110 at the mounting opening 500.

[0054] At the same time, an embodiment of the present application also provides a cable trench having an autonomously lifting cable bracket as described above.

[0055] The technical principles of the present application are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the present application and cannot be interpreted as limiting the scope of protection of the present application in any way.
