Embodiment Construction
[0010] Such as figure 1 and figure 2 As shown, an explosion-proof cable moldless heat patch has a closing and locking device, and the said closing and locking device consists of two halves 8 forming a tubular body, and the two halves 8 constitute the main body of the Huff body. A stretchable membrane cavity 10 is formed between the halves 8 . In the radial direction of each half 8, there are multiple T-shaped guide grooves 1 and explosion-proof heating cores 4, and the T-shaped guide grooves 1 are arranged axially; block 3; each half is provided with a housing 12, and a spring 2 is installed between the housing 12 and the T-shaped sliding block 3; a temperature measuring device 7 is installed on the half 8, and the temperature measuring device 7 is controlled by wire connection System 14. The control system 14 is provided with a digital display temperature indicating device and an automatic temperature control alarm device.
[0011] In this embodiment, for uniform heatin...

The invention discloses a mould-less heat compensator for explosion-proof cables and relates to the technical field of cable repair. The heat compensator comprises a closed locking device; the closed locking device comprises two half parts to form a cylindrical Haff body; a scalable mold cavity is formed between the two half parts; a plurality of T-shaped guiding grooves and explosion-proof heating cores are arranged in the radial direction of each half part; the T-shaped guiding grooves are axially arranged; T-shaped sliding blocks matched with the T-shaped guiding grooves are arranged inside the T-shaped guiding grooves; each half part is provided with a housing; a spring is arranged between the housing and the T-shaped sliding block; the half part is provided with temperature measuring equipment; the temperature measuring equipment is connected with a control system through a guide line; and the housing is provided with a quick fastener. The mould-less heat compensator for explosion-proof cables has the advantages of being light in weight because of the omission of a mould, convenient to carry, simple in operation and saves effort, safe and reliable, and suitable for the hot repair of rubber sleeve cables in inflammable places and explosive places.
Description
technical field [0001] The invention relates to the technical field of cable repair, in particular to an explosion-proof cable moldless heat repair device, which is suitable for repairing rubber-sheathed cables in underground mines and in flammable and explosive places. Background technique [0002] When the rubber-sheathed soft cable for mining is used underground, the rubber-sheathed cable will be scratched and injured by external forces such as impacts, baffles, splints, and sharp-edged stones at any time, causing the cable to tear; resulting in cable leakage, short circuit, and open circuit. If it cannot work normally, it needs to be repaired well; mainly adopt cold repair or hot repair on the well, and the cold repair method cannot meet the quality requirements, and the hot repair on the well needs to lift the cable into the well, which is laborious and laborious, and there are many matching molds for repair. Contents of the invention [0003] In order to solve the de...
