Specifically, the control system includes a console 9 and a wireless control box 13 arranged on the base 1 . The operator can control the working state of the gantry through the console 9, or a remote controller connected with the wireless control box 13 signals.

The present invention uses a built-in power supply or an external generator for power supply, and the operator can select a suitable power supply for use according to the occasion. When the condition of the laying site is good, the generator can be selected as the power supply, and then the power line is drawn from the generator and connected to the power junction box 12 on one of the lifting components 2, which can be a movable cable Gantry power supply. Due to the good condition of the laying site, the generator and the gantry can be moved together during the laying of long-distance cable trenches. However, in the cable laying or cable production process, since the possibility of moving the cable drum during the laying process is small, the device of the present invention can be directly connected to the fixed generator. When the condition of the laying site is poor, and the cable is transported in the factory area, a power supply device with a capacity that can meet the demand is installed inside the gantry of the present invention, and the gantry can operate normally without an external power supply. It depends on the capacity of the internal power supply device.

When adjusting the distance between the two lifting assemblies 2 , the exposed area of the connecting plate 15 can be enlarged or reduced as the telescopic part 5 expands and contracts.

The present invention also provides a method for using the aforementioned movable cable gantry, comprising the following steps:

After the power supply (built-in power supply or generator) is turned on, the mobile component 8 is first controlled to move the gantry to a designated position for subsequent installation of the cable tray.

After arriving at the designated position, use the remote controller or the console 9 to control all the lifting parts 62 to extend downwards so that the guide wheels 64 are in contact with the ground, and stop the work of the lifting parts 62 after the mobile assembly 8 and the base 1 leave the ground at a certain height.

The telescopic part 5 is controlled according to the size of the cable reel, and the distance between the two lifting assemblies 2 is roughly adjusted.

Control the two support feet 7 in the first group of components to drop to the ground, fix the position of the first group of components, so that the gantry cannot slide at will.

Use tools such as cranes or forklifts to hoist the cable reel between the two lifting components 2, then control the telescopic part 5 to drive the second group of components to move, precisely adjust the distance between the two lifting components 2, and make the two The bearings 4 in the lifting assembly 2 are respectively inserted into the jacks on both sides of the cable reel to complete the connection with the cable reel.

After being connected, a remote controller or console 9 can be utilized to control the lifting assembly 2 to adjust the height of the cable reel.

By controlling the supporting feet 7 and the spacing adjustment assembly 6, the height of the moving assembly 8 is lowered until the moving assembly 8 is in contact with the ground, and the supporting feet 7 and the spacing adjusting assembly 6 are separated from the ground by a certain height, and then the moving assembly 8 is controlled as required to realize the cable Disk movement. During the moving process of the moving assembly 8, the electric energy and control signal are transmitted to the drive transmission module 85 through the wiring placed in the wire slot 82, and the drive transmission module 85 drives the crawler belt 87 to move through the rotation of the wheel 96 after receiving the electric energy and control signal .

After the cable reel is installed, the operator can adjust the distance between the roller 114 and the cable reel by turning the screw 113, so that the roller 114 is close to the cable reel. The output speed of the rotary drive device 115 can control the rotation and stop of the cable drum.

When the movable cable gantry of the present invention is applied in the occasion of laying cable trenches, the moving assembly 8 cooperates with the rotation control assembly 11 to match the pay-off speed of the cable reel with the moving speed of the gantry, thereby adapting to various Terrain, to achieve "Walking while laying the cable". During this process, the gantry moves while turning the cable reel, so that the cables in the cable reel are slowly placed into the cable trench, which can not only reduce the use of laying equipment, but also reduce the cost of cables in the laying process. The lateral pressure received, thus better protecting the cable.

When the movable cable gantry of the present invention is applied in the occasion of laying through pipes, it can transport the cable reel to a suitable position and fix it. When the "feeding" speed is consistent, the side pressure on the cable can be reduced, thereby protecting the cable.

When the movable cable gantry of the present invention is used in cable production occasions, operators can use it as a cable reel handling and take-up and release rack according to production needs.

The gantry of the present invention is easy to operate, and different working modes can be selected according to the usage scenarios, and a large-scale free movement can be realized, and the application scenarios are extensive. At the same time, it has a wireless control function, and the operator can operate in a relatively safe place to avoid production accidents.

Since the present invention is mainly used in cable transportation and cable laying occasions, its mobile flexibility needs to be considered at the same time, so materials with high strength and relatively light weight are preferred, and weight-reducing holes are appropriately opened to reduce weight and increase battery life.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and replacements can also be made, these improvements and replacements It should also be regarded as the protection scope of the present invention.
