Description

Technical Field

[0001] The utility model relates to the technical field of cable maintenance, and more specifically to a railway signal control cable maintenance device. Background Art

[0002] Railway digital signal cables have the functions of transmitting analog signals (1MHz), digital signals (2Mbit / s), system control information and electric energy with a rated voltage of AC 750V or DC 1100V and below. They are suitable for transmitting control information, monitoring information and electric energy between relevant signal equipment and control devices such as railway signal automatic blocking systems, axle counting, station coding, computer interlocking, microcomputer monitoring, dispatching concentration, dispatching supervision, and high-power electric switch machines. Railway signal control cables are an important guarantee for maintaining railway operations. When the cable is damaged, it needs to be repaired by a maintenance device.

[0003] When a railway signal control cable is damaged by a disconnection, the personnel first peel the disconnection interface. Before connecting the disconnection, a cable heat shrink film is put on the disconnection and moved aside. After the disconnection is connected, the cable heat shrink film is moved to the disconnection. Then the personnel shrink the cable heat shrink film through a hot air gun, so that the cable heat shrink film is tightly wrapped around the disconnection. However, the traditional hot air gun only outputs hot air from a single direction. During use, the personnel need to constantly adjust the posture around the cable heat shrink film to fully tighten the cable heat shrink film. Due to the actual maintenance of the cable disconnection, about 30 cm of the surface skin will be peeled off. Therefore, the length of the cable heat shrink film is at least 60 cm, and the cable has several layers of skin with different effects. During maintenance, each layer needs to be covered with a cable heat shrink film. The cable heat shrink film is only shrunk by a hot air gun. The long posture adjustment makes the personnel time-consuming and laborious during maintenance, and the cable maintenance efficiency is slow. Therefore, the utility model provides a railway signal control cable maintenance device. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] Example

[0028] like Figure 1-5 As shown, a railway signal control cable maintenance device comprises an arc frame 1 and an arc frame 2, wherein the arc frame 1 and the arc frame 2 are hinged, the inner walls of the arc frame 1 and the arc frame 2 are fixedly connected with an arc-shaped air guide tube 3, the sides of the arc frame 1 and the arc frame 2 close to each other are fixedly connected with a metal mesh plate 4, and one side of the metal mesh plate 4 is fixedly connected with a heating resistance wire 5;

[0029] A handle 6 is fixedly connected to the outer circumferential surface of the arc frame 1, a shell 7 is fixedly connected to one side of the handle 6, a motor 8 is fixedly connected to the inner wall of the shell 7, a fan blade 81 is fixedly connected to the output end of the motor 8, a three-way pipe 9 is fixedly connected to the upper end of the shell 7, one output port of the three-way pipe 9 is connected to the arc-shaped air duct 3 in the arc frame 1, and a hose 91 is fixedly connected to the other output port of the three-way pipe 9, and the hose 91 is connected to the arc-shaped air duct 3 in the arc frame 2 2.

[0030] When in use, after the arc frame 1 and the arc frame 2 are sleeved on the periphery of the cable heat shrink film, the heating resistor wire 5 and the motor 8 are energized, and the heating resistor wire 5 can heat the metal mesh plate 4. At the same time, the motor 8 drives the fan blades 81 to rotate, and the wind force generated by the fan blades 81 will pass through the three-way pipe 9 and the hose 91 to the arc-shaped air guide pipe 3, and finally blow to the metal mesh plate 4. The wind force carries the heat and blows to the cable heat shrink film in a ring shape, so that the cable heat shrink film is tightened. The personnel do not need to constantly adjust their posture to make the surface of the cable heat shrink film fully heated. During specific operation, the arc frame 1 and the arc frame 2 can be moved horizontally after being sleeved on the periphery of the cable heat shrink film, which is convenient for personnel to operate and use, and improves maintenance efficiency;

[0031] Similar to using a hot air gun, power the heating resistor 5 and the motor 8 through a mobile power supply;

[0032] The three-way pipe 9 and the arc-shaped air guide pipe 3 in the arc-shaped frame 2 2 are connected by a hose 91 , and the flexibility of the hose 91 will not affect the opening of the arc-shaped frame 2 2 .

[0033] like Figure 1-2 As shown, a connecting block 21 is fixedly connected to the outer circumferential surface of the arc-shaped frame 2, a spring piece 22 is fixedly connected to one side of the connecting block 21, and one end of the spring piece 22 is fixed to the handle 6.

[0034] When in use, the connecting block 21 is pressed to separate the arc frame 2 from the arc frame 1, and then the arc frame 1 and the arc frame 2 can be sleeved on the periphery of the cable heat shrink film. After the connecting block 21 is released, the rebound of the spring piece 22 will lift the connecting block 21, so that the arc frame 2 and the arc frame 1 are tightly closed, thereby improving the overall stability during use.

[0035] like Figure 1-2 As shown, the surface of the handle 6 is provided with a flexible layer 61 .

[0036] When in use, the flexible layer 61 improves the comfort of a person when holding the handle 6 .

[0037] like Figure 1 As shown, a heat-insulating frame 41 is fixedly connected to the side of the metal mesh plate 4 .

[0038] When in use, the heat on the metal mesh plate 4 is not easily directly transferred to the arc frame 1 or the arc frame 2 2 through the heat insulation frame 41, so as to prevent the surface temperature of the arc frame 1 or the arc frame 2 2 from being too high, thereby causing safety hazards.

[0039] like Figure 1 As shown, a vent hole 71 is opened at the lower end of the shell 7, and a dustproof net 72 is fixedly connected to the inner wall of the vent hole 71.

[0040] When in use, the vent holes 71 allow air to circulate in the housing 7 , ensuring that the rotating blades 81 can generate wind force, and preventing dust and other debris from entering the housing 7 through the dustproof net 72 .

[0041] like Figure 1 As shown, the inner top end of the housing 7 is inclined.

[0042] When in use, the wind force can be concentrated and output through the diversion of the inclined side.

[0043] In summary, the specific working process of the present scheme is: after the arc frame 1 and the arc frame 2 are sleeved on the periphery of the cable heat shrink film, the heating resistor 5 and the motor 8 are energized, the heating resistor 5 can heat the metal mesh plate 4, and at the same time, the motor 8 drives the fan blades 81 to rotate, and the wind force generated by the fan blades 81 will pass through the three-way pipe 9 and the hose 91 to the arc-shaped air duct 3, and finally blow to the metal mesh plate 4. The wind force carries heat and blows toward the cable heat shrink film in a circular shape, so that the cable heat shrink film is tightened. Personnel do not need to constantly adjust their posture to make the surface of the cable heat shrink film fully heated. During specific operation, the arc frame 1 and the arc frame 2 can be moved horizontally after being sleeved on the periphery of the cable heat shrink film, which is convenient for personnel to operate and use and improves maintenance efficiency.

[0044] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
