Description

A portable movable multi-angle cable intermediate joint clamping workbench

technical field

The utility model belongs to the field of electric power engineering and relates to electrical appliances, in particular to a portable movable multi-angle cable intermediate joint clamping workbench.

Background technique

With the development of electric power construction, the rate of cables in cities is gradually increasing. The cableization of 10kV distribution lines is the need and inevitable way for the development of electric power in cities. The cable brings many benefits to the line operation. At the same time, because there are a large number of cable intermediate joints in the cable, the quality and production of the cable intermediate joints directly affect the use of the cable, and the faults caused by it have caused great trouble to the distribution network operation of the power supply department. . In 2016, there were 23 line failures in an urban power supply company in a city, 16 of which were due to cable intermediate joints, accounting for nearly 70%. Of the 16 intermediate joint failures, analysis showed that 12 were due to production quality, accounting for 70% of the total. than nearly 75%. It can be seen that the production quality of cable intermediate joints has greatly affected the safe operation of the highly cabled distribution network. Strictly requiring the production of cable intermediate joints is the primary technical problem to be solved. However, the following problems exist in the prior art:

1. Usually, the production of cable intermediate joints requires the cooperation of two maintenance and construction personnel. One of them fixes one end of the disconnected cable by hand, and the other performs stripping and cutting of the cable intermediate joints. During the working process, the person holding the broken cable needs to keep turning the cable according to the progress of the cable intermediate joint process to meet the operating angle required by the intermediate joint production personnel. In many cases, the cooperation of two people cannot meet the unified requirements. Seriously affect the work efficiency and the production quality of cable intermediate joints;

2. On the other hand, the technical level of construction personnel is also a key factor affecting the production quality of cable intermediate joints. At present, in the production of cable intermediate joints, the inheritance of construction technology is still at the level of traditional masters with apprentices, and there is a lack of effective and reliable technical certification. . This leads to uneven technical levels of construction personnel, and the production quality of cable intermediate joints largely depends on the technical experience of construction personnel. When the supply and demand relationship of cable intermediate joint production is relatively balanced, the quality of cable intermediate joint production is relatively reliable, and when there is a peak demand for cable intermediate joint production, such as the peak construction of power cable projects, construction personnel with low technical levels will often participate. The production quality of the cable intermediate joints is relatively low, and after the cable has been running for a period of time, the failure rate of the cable intermediate joints is relatively high;

3. Furthermore, consider the on-site facility standards for the production of cable intermediate joints, especially the heat-shrinkable cable intermediate joints have higher requirements for the production environment due to their technological requirements, and usually the production of cable intermediate joints is done in narrow, dark and humid cables. It is completed in the trench, and the narrow space makes it difficult for the construction personnel to construct, and the cable intermediate joint lacks support during the construction process, and is prone to failure due to internal stress and external tension.

Advantage and beneficial effect of the present utility model are:

1. The utility model manufactures a mobile portable multi-angle conversion cable intermediate joint clamping workbench, which solves the problem of lack of support for the cable intermediate joint. On the one hand, it ensures that the main body of the cable is stable when the cable intermediate joint is made, which is beneficial to the accurate size of the disconnected cable, and ensures that the joint is not affected by internal stress and external tension after the joint is completed. During the working process, only one repairing construction worker is needed to fix and clamp the cable intermediate connector on the workbench through the clamp bolt, slide out the retractable working plate with the help of the slideway, and position the detachable clamp bolt to the cable head, then perform maintenance. The construction personnel can turn the angle changing mechanism to the required angle to work, which further improves the work efficiency and improves the production quality of the cable intermediate joint. On the other hand, the telescopic support rod of the bottom support frame ensures that the support height is higher than the cable channel to a certain extent during the production process, preventing water vapor and dust from staying in the middle joint, and the establishment of the golden triangle effectively ensures the stability of the support point sex. This design further regulates the on-site facilities and construction standards for cable head production, including weather and construction environment, so that the on-site construction environment meets the process requirements. At the same time, the waterproof sealing and corrosion resistance of the cable intermediate joint are improved, which can effectively reduce the cable failure caused by the water entering the cable intermediate joint after the cable is put into operation.

Aiming at the cause of failure of the cable intermediate joint, the utility model improves the production quality of the cable intermediate joint by making a mobile portable multi-angle conversion cable intermediate joint clamping workbench, refines the production process of the cable intermediate joint, and ensures that construction personnel Put more energy on key points of quality control. Ensure that the production process of cable intermediate joints meets the needs of process control, and achieve the same standards for construction and acceptance. On the other hand, in the past, the tools used to make cable intermediate joints were relatively primitive, such as electrician's knife and wire cutters. When making cable heads, such as stripping, chamfering and other processes, it relied on the technical level and construction experience of the construction personnel. , It is difficult to determine whether the cutting depth and chamfering angle are appropriate. However, through the design of the utility model, the past relying on personal technology is transformed into relying on the clamping workbench to realize accurate and reliable production of cable intermediate joints, effectively improving the standardization of cable intermediate joint production, greatly improving the construction technology level, and effectively solving the problem of cable joints. The technical problems in the production of intermediate joints are suitable for vigorous promotion and use.
