Detailed Description
The structure and features of the present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that various modifications can be made to the embodiments disclosed herein, and therefore, the embodiments disclosed in the specification should not be construed as limiting the present invention, but merely as exemplifications of embodiments thereof, which are intended to make the features of the present invention obvious.
Because the motor performs eccentric rotation motion when the vibroflot performs hole forming, a strong horizontal exciting force can be generated, and the silt on the operation surface of the vibroflot is mixed, the environment is severe, and if a common signal cable is used for transmitting signals, the signal cable is very easy to be pulled apart, and the signal transmission cannot be continuously, stably and reliably carried out; if the thickness of the protective layer of the signal cable is simply increased, the manufacturing cost of the signal cable is inevitably increased, so the utility model fully utilizes the power supply cable of the vibroflot to reform the power supply cable, and provides the cable special for vibroflot equipment.
As shown in fig. 1, the special cable for the vibroflotation device provided by the utility model is a 5-core cable. The cable comprises a protective layer 1, a waterproof layer 2, a filling layer 3, three power cable cores 4, a grounding cable core 5, a signal cable core 6 and a rubber strip 7.
The outermost layer of the special cable is a protective layer 1 which can be made of polyether type thermoplastic polyurethane elastomer and mainly plays a role in protection. The waterproof layer 2 is closely attached to the protective layer, and the main function of the waterproof layer is to prevent water on the working surface of the vibroflot from entering the cable to cause short circuit due to the damage of the surface of the protective layer 1. The waterproof layer 2 can be woven by polyester yarns, and waterproof paint is brushed on the surface of the waterproof layer. The packing layer 3 is closely attached to the waterproof layer, and the packing layer 3 can be filled with insulating polypropylene materials or glass fiber materials or PP materials or hemp ropes.
Three power cable cores 4, a grounding cable core 5 and a signal cable core 6 are embedded in the filling layer 3. The power cable core 4 is respectively connected with A, B, C three-phase power supplies to provide working power supply for the vibroflot. The grounding cable core 5 is connected to the ground.
The signal cable core 6 is positioned among the three power cable cores 4 and the grounding cable core 5, is positioned in the center of the whole cable and is used for transmitting signals. The outermost layer of the signal cable core 6 is a protective layer 61, the intermediate layer 62 is a metal shielding layer, and the innermost layer is an insulating sheath 63. The middle metal shielding layer mainly plays a role in resisting interference. The signal cable core 6 is connected with signal output ends of an oil temperature detection device, a motor rotating speed detection device, a vibroflotation device deflection detection device in the pile making process, a pile body depth measurement device and the like which are arranged on a motor, and is used for transmitting data and realizing the monitoring of the working state of the vibroflotation device in the construction process.
In order to enhance the tensile resistance, the pulling resistance and the flexibility of the utility model, as shown in the figure, a plurality of rubber strips 7 are additionally arranged in the filling layer. The rubber strip 7 is arranged among the power cable core 4, the grounding cable core 5 and the signal cable core 6. In the preferred embodiment of the utility model, the rubber strip 7 is arranged between the power cable core 4 and the grounding cable core 5, and of course, the rubber strip 7 can also be arranged between the power cable core 4 and the signal cable core 6 and between the grounding cable core 5 and the signal cable core 6.
The sizes of the wire diameters of the power cable 4, the ground cable 5 and the signal cable 6 constituting the present invention are performed according to the relevant national standard specifications. The materials of the protective layer, the waterproof layer, the filling layer, the metal shielding layer, the insulating layer and the sheath of the outer layer of the cable can be determined according to the manufacturing process, the use working condition and the use environment.
