Single-level safety wire installation and maintenance instructions

1. Installation instructions Before installing the trolley wire, firstly install the angle bracket according to the user's choice of installation type. According to the suspension of the trolley wire, fix it and install it on the slippery wire of every 6 meters at the installation site. The required suspension seat, and one end of both end joints jacket, one end is also equipped with an aluminum joint, when installing aluminum joints, it should be noted that only the aluminum rail can be extended into the joint 1/2 for another rail connection, above After the work is ready, suspend one by one wire on the bracket for full-line connection, and tighten the screws for each connector when connecting. When the total length of the trolley line exceeds 200 meters, a telescopic device (telescometer provided by the factory) shall be installed. When the power cable is connected to the line, it may be connected at a joint of every 6 meters. The specific connection method can refer to the front Connector device diagram.

When installing a curved trolley line, the suspension distance should be shortened accordingly. The specific dimensions can be determined according to site conditions.

When installing the conductive device, the conductive device is first installed on the matching square tube, and the appropriate position matched with the trolley line is selected to be fixed on the electric equipment. Attention should be paid to the good tracking performance of the conductive device and the trolley wire. For good contact pressure, the conductor and trolley wire should be installed in the same vertical and horizontal direction.

2. Maintenance The safety wire contact line should be checked regularly during normal operation, because the power equipment is the main production tool of each industrial and mining enterprise. It will directly affect the production efficiency of the factory. When checking the trolley wire, check whether there is any looseness and disengagement at every 6m. When checking the conductive device, check whether the movable part is flexible, whether the tension spring is fatigued, the brush is worn, etc. (These conditions will affect To track the conductive properties and the tracking performance of the conductor should be adjusted in time).

During the renovation of holiday equipment, the conductive device is pulled out of the catheter and the brush roller of the conductive device is inspected for wear. If the brush is less than the specified effective length, it must be promptly replaced. When the guide roller is deformed seriously, it must be replaced to maintain the conductive device. Run normally and brush well and check the cause. Safe slide wire In all parts, the brush is the only part that will normally wear out.

For severely corrosive gas environments, the corrosion of brackets, hangers, and retractors must be checked and measures must be taken to apply anti-rust materials.

Use the place where the trolley wire is used, such as when performing infrastructure. Do not; hit, hit the pressure transmission conduit, but are not allowed to press the weight on the transmission conduit. Prevent deformation and cracking of power transmission conduits, affect their use, and cause safety accidents. After the infrastructure is completed, the infrastructure waste on the power transmission conduit should be immediately removed.

During normal maintenance, workers are not allowed to step on the power transmission conduit or its support to prevent damage to the flatness of the entire line and accidents.

Hydraulic power expansion external casing packer is mainly composed of the expansion sleeve, base pipe (casing), valve joints, collar, sub and other components which can be directly connected with the casing string.

There are are two structures of valve joint, one is radial valve system, and the other is axial valve system, radial valve system is composed of a set of three valves (open valve, single-flow valve, pressure limiting valve) radial arrangement of the axial valve system is composed of a Set of axial double valve (open valve, pressure limiting valve) composition.

Axial valves and valve joint have two radial valve system structure, radial valve system is composed of a set of three valves (open valve, single valve, pressure limiting valve) which is radial arrangement, and axial valve system is a set of two valves (open valve, pressure limiting valve) which is axial arrangement.
