[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 , Figure 2 As shown in Figure 4, in this embodiment, a special cable structure for a gourd-shaped power supply four-in-one signal cable includes a cable body 1, which includes two steel wire ropes 101. A connecting component 2 is installed at both ends of the two steel wire ropes 101. The connecting component 2 includes a base plate 201 and a pressure plate 203. The pressure plate 203 is hinged to one end of the base plate 201. Two contact grooves 202 are opened on the outer walls of the base plate 201 and the pressure plate 203, which are close to each other. The steel wire ropes 101 pass through the two contact grooves 202. An extension clip 204 is fixedly connected to the outside of the movable end of the base plate 201 and the pressure plate 203. The two extension clips 204 are equipped with the same fixing structure, which includes a screw 205 and a locking cap 206.

[0025] Both extension clips 204 have a groove inside. The screw 205 is rotatably connected to the groove of the extension clip 204 at the end of the pressure plate 203. The locking cap 206 is threaded to the outside of the screw 205. The width of the locking cap 206 is greater than the width of the groove of the extension clip 204 at the end of the pressure plate 203.

[0026] Both the base plate 201 and the pressure plate 203 have several connecting holes 208 inside their hinged ends. By passing bolts through the connecting holes 208, the base plate 201 and the pressure plate 203 can be connected to external equipment, and the end of the wire 102 can be fixed.

[0027] The outer surface of the locking cap 206 is fixedly connected with several equally spaced extension pieces 207, which allows the locking cap 206 to be twisted without the aid of tools.

[0028] Fold one end of the wire rope 101 into a U-shape, and then place the end of the wire rope 101 into the two contact grooves 202 of the base plate 201. Next, flip the pressure plate 203 close to the base plate 201, and make the two contact grooves 202 on the outside of the pressure plate 203 cover the outside of the end of the wire rope 101. Then, flip the screw 205 so that it enters the groove of the extension card 204 at the end of the base plate 201. Rotate the locking cap 206 to move it up along the thread of the screw 205 until the locking cap 206 presses tightly on the extension card 204, so that the movable end of the base plate 201 and the pressure plate 203 tightly clamp the wire rope 101. Under the action of friction, the wire rope 101 cannot be separated from the contact groove 202 by external force.

[0029] like Figure 1 and Figure 3As shown, the cable body 1 also includes a conductor 102 and three signal line bodies 103 (the three signal line bodies 103 are respectively a control line (transmitting control signals to realize the start, stop, direction switching (up / down) and speed adjustment of the electric hoist), a signal line (transmitting status feedback signals, such as limit switch status, load weight, running speed, etc., used for monitoring and protecting equipment), and an optical fiber line (in environments requiring high-speed data transmission or strong electromagnetic interference, it replaces the traditional signal line to transmit control or monitoring signals)). The conductor 102 and the three signal line bodies 103 are located in the middle of the cable body 1, and the three signal line bodies 103 are evenly distributed outside the conductor 102. The conductor 102 and the three signal line bodies 103 are wrapped with a wrapping layer 105, and a filling layer 104 is filled between the wrapping layer 105 and the conductor 102 and the three signal line bodies 103.

[0030] The outer wrapping layer 105 is fixedly wrapped with a reinforcing layer 106. The reinforcing layer 106 is fixedly fitted with an inner sheath 107 (as a primary protective layer, isolating the internal structure from the external environment, and possessing certain oil and corrosion resistance). Two steel wire ropes 101 are fixedly inserted into the outer side of the inner sheath 107. The outer sheath 108 is fixedly fitted on the outer side of the inner sheath 107 (wear-resistant, oil-resistant, UV-resistant, anti-aging, adaptable to harsh industrial environments, and protecting the internal structure).

[0031] The filler layer 104 is made of aramid fiber, the wrapping layer 105 is made of polyester tape, the reinforcing layer 106 is made of aramid fiber, the inner sheath 107 is made of polyvinyl chloride, and the outer sheath 108 is made of polyurethane.

[0032] The filling layer 104 between the three signal line bodies 103 and the conductors 102 is made of aramid fiber. This fiber is five times stronger than steel and also has the characteristics of high temperature resistance, cut resistance and fatigue resistance. It can maintain the round structure, prevent the signal line bodies 103 and conductors 102 from loosening or deforming, and enhance their compression resistance. The outer wrapping layer 105 is made of polyester tape, which can fix the internal structure, prevent conductor displacement and improve mechanical stability. The outermost reinforcing layer 106 is an aramid fiber braided layer, which can enhance the tensile strength and bending resistance of the cable, withstand the tension when the electric hoist moves frequently, extend the service life and improve the service life of the cable.

[0033] This utility model provides a special cable structure for a gourd-shaped four-in-one signal cable with power supply. The specific working principle is as follows:

[0034] When the device is in operation, first connect the wire 102 and the three signal line bodies 103 to the corresponding positions on the equipment. Then connect the wire rope 101 and the connecting assembly 2, fold one end of the wire rope 101 into a U-shape, and then insert the end of the wire rope 101 into the two contact grooves 202 of the base plate 201. Next, flip the pressure plate 203 close to the base plate 201, and make the two contact grooves 202 on the outside of the pressure plate 203 cover the outside of the end of the wire rope 101. Then, flip the screw 205 to let it enter the base plate 201. Inside the groove of the extension card 204 at end 01, rotate the locking cap 206 to move it up along the thread of the screw 205 until the locking cap 206 presses tightly against the extension card 204, so that the movable ends of the base plate 201 and the pressure plate 203 tightly clamp the wire rope 101. Under the action of friction, the wire rope 101 cannot be separated from the contact groove 202 due to external force. Then, the base plate 201 and the pressure plate 203 are connected to the external equipment by passing the bolt through the connecting hole 208, and the end of the wire rope 101 can be fixed.

[0035] The filling layer 104 between the three signal line bodies 103 and the conductors 102 is made of aramid fiber. This fiber is five times stronger than steel and also has the characteristics of high temperature resistance, cut resistance and fatigue resistance. It can maintain the round structure, prevent the signal line bodies 103 and conductors 102 from loosening or deforming, and enhance their compression resistance. The outer wrapping layer 105 is made of polyester tape, which can fix the internal structure, prevent conductor displacement and improve mechanical stability. The outermost reinforcing layer 106 is an aramid fiber braided layer, which can enhance the tensile strength and bending resistance of the cable, withstand the tension when the electric hoist moves frequently, extend the service life and improve the service life of the cable.
