Description

Technical Field

[0001] The utility model relates to the technical field of cable construction facilities, in particular to a cable laying, arranging and lifting device. Background Art

[0002] A lifting device for laying cables at the tunnel top is a device designed specifically for cable laying within tunnels, primarily to improve the efficiency, safety, and accuracy of cable laying. Cable laying is a critical step in tunnel construction, particularly in the confined spaces of tunnels. Traditional manual laying methods are time-consuming and pose safety risks. Using an electric or hydraulic lifting mechanism, the lifting device can quickly and precisely raise the cable to the tunnel top or a designated location, eliminating the dangers of manual handling and overhead work, and reducing the risk of worker injury. The structure of this type of lifting device includes a bracket, lifting mechanism, guide device, and control system. The bracket is usually made of high-strength steel and supports the entire lifting system; the lifting mechanism is driven electrically or hydraulically and is responsible for lifting the cable to the target position; guide devices such as pulleys and guide rails are used to ensure the stability of the cable during the lifting process to prevent entanglement or damage; as disclosed in the authorization announcement number CN209419113U, a tunnel cable lifting device includes a clamping assembly that is sleeved on the pillar and slidably connected to the pillar and is used to clamp the cable, and a locking assembly is provided at the upper end of the pillar and is used to lock the clamping assembly; the clamping assembly includes: a support plate, which is sleeved on the pillar and slidably connected to the pillar; a clamping plate, which is slidably connected to the upper side of the support plate and cooperates with the support plate to clamp the cable; the support plate and the clamping plate There are places for cables to be embedded and placed on the top. When the motor drives the take-up wheel to rotate and reel the pulling wire, the support plate rises together with one end of the pulling wire until the support plate rises to the upper side of the locking block. However, during the use of this technical solution, multiple lifting devices need to be arranged in the extension direction of the cable to allow the entire cable to be applied to the top of the tunnel and facilitate subsequent staff to position the cable. When the above-mentioned multiple lifting devices are used to ensure that the cables are evenly and accurately arranged on the top of the tunnel, each lifting device needs to be equipped with multiple components such as motors, take-up wheels, control systems, and guide devices. Each component involves high-quality mechanical equipment and electronic control technology, which brings higher equipment costs and maintenance costs during use. Utility Model Content

The staff connects the cable to be lifted to the supporting structure 7 to ensure that the cable is firmly connected to avoid loosening or falling off during the lifting process. When connecting, pay attention to the direction of the cable to ensure that it will not interfere with other equipment. After confirming that the cable is placed stably, the staff The staff manually operates the double-column screw lifting structure 4, and slowly lifts the I-beam 3, U-shaped vertical plate 5, secondary slide 6, and supporting structure 7 manually. The operator needs to closely observe the status of the cable to ensure that it remains stable during the lifting process to avoid twisting or stretching.

At this time, the cable is supported and lifted by the device, and the staff can fix, limit, and other operations on the cable at this location. After the cable is fixed to the tunnel top wall, the device can be removed.
