Description

A cable fixing sleeve for training

technical field

The utility model relates to a cable fixing sleeve for training.

Background technique

Among the small types of power cable jobs, cable joint workers have the most complicated process, and have the highest requirements for the technical level of employees, and have a great influence on the quality of the project. The ability evaluation of cable joint workers has been highly valued. During the training, the length of the cables handled by the actual operation was about one meter. However, due to the lack of a reliable short-section cable fixing device, only cables of more than two meters were used for the assessment. After the first assessment, the remaining untreated cables had to be discarded. Training and assessment costs are high.

At present, the short-section cable fixing devices on the market generally adopt the Haval structure. This structure is simple and easy to install, but the requirements for the outer diameter of the cable are relatively high. If the cable is too thin or too thick, it is necessary to open several specifications. Only in order to meet the installation needs, can not be reused, but also increased the cost. There is also a short-section cable fixing device that adopts a tight screw structure. This structure requires a certain margin for the thickness of the cable. It is only necessary to tighten the screws when fixing. The area is related, and the degree of tightness is related to the size of the selected screw. When the force is large, the cable is prone to slip and cause injury to the operator. In addition, most of the Haval structure and the tight screw structure are rough in appearance, simple in structure, and ordinary materials are not suitable for frequent disassembly and assembly. There is also a third structure, the adjustable opening fixing device, which combines the advantages of the Haval structure and the screw structure. The production is difficult and the selection of materials is exquisite, which will increase the cost of training and assessment, which is uneconomical.

detailed description

Below, according to Fig. 1 and Fig. 2, the preferred embodiment of the present utility model will be described in detail.

As shown in Figure 1, the utility model provides a cable fixing sleeve for training, which includes a sleeve main body 1 and clamping parts 2 arranged at both ends of the sleeve main body 1, and also includes several supporting legs 3 connected to the sleeve main body 1 , and the base 4 connected to the support leg 3, the clamping part 2 is used to clamp and fix the short section of cable, the sleeve main body 1 is used to extend and support the short section of cable, the sleeve main body 1 is fixed on the base through the support leg 3 4, it is convenient for cable joint workers to carry out assessment and training.

The clamping part 2 includes a housing 24 and several clamping components 21 arranged on the housing 24 .

The housing 24 includes an openable part 201 and a fixed part 202. One end of the openable part 201 and the fixed part 202 is connected by a hinge 22, and the other end is fixedly connected by a fastener 23. When installing a short cable , remove the fastener 23, open the openable part 201, put the short section of cable into the housing 24, then close the openable part 201, fasten the openable part 201 and the fixed part 202 through the fastener 23, in When disassembling the short section of cable, take off the fastener 23, open the openable part 201, and take out the short section of cable. The housing 24 adopts a hinge connection structure, which is convenient for installation and disassembly of the cable.

The clamping assembly 21 includes a guide housing 212 fixed on the housing 24 , a screw 211 threadedly connected with the guide housing 212 , and a clamping slider 213 disposed in the guide housing 212 .

The contact surface between the clamping slider 213 and the cable is a cross-toothed surface 214 .

After putting the short section of cable into the housing 24, adjust the screw rod 211, push the clamping slider 213 to clamp the cable, and the cross-toothed surface 214 on the clamping slider 213 is embedded in the outer sheath of the cable, and the cable is tightly fixed .

The number of clamping components 21 is greater than or equal to 3, and surface contact is adopted between the clamping slider 213 and the cable, which increases the clamping area and prevents accidental loosening of the cable when it is subjected to external force. The intersecting toothed surfaces 214 prevent radial sliding and rotation of the cable.

The diameter of the clamping slider 213 is selected according to the diameter of the cable. If the diameter of the cable is larger, the diameter of the clamping slider 213 is also larger, so as to better clamp the cable.

The sleeve main body 1 and the housing 24 of the clamping part 2 are made of stainless steel tubes, which ensures the strength of the device, is beautiful and rust-proof, can be used repeatedly for a long time, and can clamp all known commonly used cables, suitable for 10kV~ 220kV cables.

The supporting leg 3 adopts a telescopic structure, and its height is adjustable, so as to adapt to the working posture and construction activities of the cable connector workers.

The base 4 adopts the board commonly used in the assessment and training of cable connector workers.

The outer diameter of the three-core cable used in the assessment and training of cable connector workers is not theoretically circular, and the inner filler of the cable is mostly paper. If the clamping position is in the gap of the three-core cable, the cable may not be fixed. When it loosens suddenly, it may cause injury to the operator. The utility model provides a cable fixing sleeve for training, which abandons the usual method of directly clamping the cable by the screw rod, and adopts a clamping slider with a guiding structure as the clamping sleeve. The clamping point effectively increases the contact area and provides greater clamping force, so that the entire cable does not come out or rotate. The contact surface between the clamping slider and the cable is a cross-toothed surface, which effectively transmits the clamping force to the The wire core of each phase prevents any wire core from rotating during operation, effectively avoiding the possibility of sliding between the cable sheath and the clamping block. The cable fixing sleeve provided by the utility model can be reused, which is convenient The cable is disassembled, and the device is light and easy to move.

In the original training and assessment, about 1 meter of cable could not be reused for every 2 person-times. After using the cable fixing sleeve for training provided by the utility model, the clamping part of the cable is at least 20cm, and the cable used for training and assessment There is basically no waste, and short cables with a length of about 1 meter can be fully utilized.

The following is the comparison of the device cost required for the original training and the cost of the device required after training with the cable fixing sleeve provided by the utility model. As can be seen from the table, after using the cable fixing sleeve provided by the utility model After the training cable is used to fix the sleeve, based on the calculation of 1,000 person-times of training/assessment per year, the investment of fixing device cost is 6,201 yuan, which can save a total of 422,799 yuan in training costs, creating huge economic benefits.

Shanghai Electric Power Company, as a typical representative of state-owned super-large power enterprises, organized a large-scale cable joint worker ability assessment for the first time. Using the cable fixing sleeve for training provided by the utility model, it broke through the bottleneck that restricts the practical assessment of cable joint workers all over the country. --The cost is high, and the oral test is used instead of the practical test--the first to realize the full-coverage large-scale all-weather outdoor practical cable joint worker ability test.
