Description

Technical Field

[0001] This utility model relates to the field of tunnel cable support technology, and specifically to a tunnel cable support that is easy to install. Background Technology

[0002] With the steady advancement of the national policy on infrastructure construction in southwestern China, large-span deep-earth tunnel projects have become a major component of the construction process. As tunnel excavation progresses, the working environment in the initial support section deteriorates. Electricity, being the core of the project, is crucial for the safety of on-site personnel due to the stability of its transmission process and the method of cable laying. During tunnel construction, cable supports are typically used to install and support cables, facilitating cable laying and ultimately enabling tunnel construction.

[0003] The existing cable support consists of a vertical pole and multiple horizontal poles. The vertical pole is fixed to the tunnel wall with expansion bolts, and one end of the horizontal pole is fixed to the vertical pole by welding. Since the cable support is welded, the number of horizontal poles is relatively fixed. During cable laying, there may be a problem that the number of horizontal poles is insufficient to meet the number of cables to be laid. At this time, it is necessary to add more cable supports. The added cable supports cannot be fully utilized, resulting in a waste of resources. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a convenient tunnel cable support. This addresses the issue that cable supports are welded together, resulting in a relatively fixed number of crossbars. During cable installation, the number of crossbars may be insufficient to meet the required number of cables, necessitating the addition of additional cable supports. However, these additional supports cannot be fully utilized, leading to resource waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A conveniently installed tunnel cable bracket includes an installation plate fixed to the tunnel sidewall. Multiple support plates are detachably mounted on the installation plate. One end of each support plate has a guide plate. Multiple evenly distributed guide grooves for the guide plates to engage are formed on the outer end face of the installation plate. A guide groove is formed in the installation plate below the guide grooves, allowing the guide plates to engage and then displace downwards. A receiving groove communicating with the guide grooves is formed in the installation plate above the guide grooves. A fastening block capable of sealing the guide grooves is slidably mounted within the receiving groove. A pushing block extending to the outer side of the installation plate is provided on one side of the fastening block, and symmetrical assist rods are provided on both sides of the pushing block.

[0007] As a preferred embodiment of this utility model, a sliding groove is provided in the mounting plate, and a sliding rod with one end connected to the fastening block is slidably disposed in the sliding groove.

[0008] By using the above technical solution and the sliding rod and sliding groove, the stability of the vertical displacement of the fastening block is improved.

[0009] As a preferred technical solution of this utility model, a drive spring is coaxially sleeved on the outer side of the sliding rod. One end of the drive spring is connected to the fastening block, and the other end of the drive spring is connected to the inner side wall of the top of the receiving groove.

[0010] By utilizing the above technical solution and the driving spring, the fastening performance of the fastening block as it passes through the guide groove and is inserted into the guide groove is improved.

[0011] As a preferred embodiment of this utility model, the mounting plate is provided with a travel groove for the displacement of the push block, and the travel groove is connected to the receiving groove.

[0012] As a preferred technical solution of this utility model, the fastening block has a first locking hole through which a locking bolt is inserted, and the mounting plate has a second locking hole that communicates with the first locking hole.

[0013] By using the above technical solution, the first and second locking holes, along with the locking bolts, can limit and fix the displacement of the fastening block, while also improving the connection strength between the mounting plate and the bearing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When additional support plates are needed, the push block is first driven by the assist rod to move the fastening block upwards and fully retract it into the receiving groove, thereby releasing the fastening block from blocking the guide groove. The guide plate on the support plate is then aligned with the guide groove and inserted. Next, the support plate is moved downwards so that the guide plate is inserted from the guide groove into the guide groove, thus initially fixing the support plate to the mounting plate. Then, the assist rod is loosened to move the fastening block downwards through the guide groove and insert it into the guide groove, sealing the guide groove and simultaneously pressing and fixing the guide plate in the guide groove. At this point, the first locking hole on the fastening block connects with the second locking hole on the mounting plate. A locking bolt is inserted into the connected first and second locking holes for fixation, thereby limiting and fixing the displacement of the fastening block. This invention facilitates the replenishment of support plates by workers according to the number of cables laid on site, and also facilitates the replacement of damaged support plates.

[0022] Example

[0023] This utility model provides a tunnel cable bracket that is easy to install, see reference. Figure 1-3 As shown, the installation includes a mounting plate 1 fixed to the tunnel sidewall. Multiple support plates 2 are detachably mounted on the mounting plate 1 and perpendicular to it. One end of each support plate 2 has an integrally formed guide plate 13. The integral structure of the guide plate 13 and the support plate 2 improves the connection strength between them. Multiple evenly distributed guide grooves 4 are formed on the outer end face of the mounting plate 1 for the guide plates 13 to engage with. Below the guide grooves 4, a guide groove 5 is formed in the mounting plate 1 for the guide plates 13 to engage with the guide plates 13 and then move downwards for insertion. An accommodating groove communicating with the inlet groove 4 is provided in the mounting plate 1 above the inlet groove 4. A fastening block 10 that can block the inlet groove 4 is slidably provided in the accommodating groove. By setting the fastening block 10, the guide plate 13 in the guide groove 5 can be limited and the guide plate 13 can be pressed and fixed. A pushing block 7 extending to the outside of the mounting plate 1 is provided on one side of the fastening block 10. Assist rods 8 are symmetrically provided on both sides of the pushing block 7. By setting the assist rods 8, it is convenient for the staff to drive the pushing block 7 to move the fastening block 10 up and down.

[0024] The mounting plate 1 has a travel groove 6 for displacing the push block 7, and the travel groove 6 is connected to the receiving groove.

[0025] The fastening block 10 has a first locking hole 9 through which a locking bolt 3 is inserted, and the mounting plate 1 has a second locking hole that communicates with the first locking hole 9.
