Problems solved by technology

[0003] In order to overcome the deficiencies in the prior art, the purpose of the present invention is to provide a cable laying traction device, which can monitor the traction force in real time, and when it exceeds the set value, it will stop for protection and prevent the cable from being damaged by excessive traction force; at the same time, the active friction wheel is used to The pressure between the driven friction wheel and the driven friction wheel can be adjusted to indirectly control the output torque of the driven friction wheel. When the set traction force is exceeded, the driving and driven friction wheels will slide relative to each other to avoid damage to the cable and provide double protection for the cable. The role of the cable completely eliminates the phenomenon of excessive traction and damage to the cable; in addition, the use of a two-speed motor effectively improves the construction efficiency

specific Embodiment 1

[0037] Specific Example 1: Cable Model: Zryjv22-8.7 / 103 × 120mm 2 , This cable is a copper -core cable with a cross -sectional area of 3 × 120mm 2 If the 3 -phase copper core is trapped at the same time, the cross -sectional area is 360mm 2 The maximum dedestion TMAX = 68ac = 68 × 360 = 24480 Newton.If the two cores are trapped, TMAX = 68ac = 68 × 240 = 16320 Newton.Based on the above calculation value, when the traction model is ZRYJV22-8.7 / 10, the 3 -phase copper core cable is set first, first set the protection movement value of the traction detection device 17 to 24,480 Newton.Then set the maximum catering value of the motion friction wheel 16, and the maximum traction value of the motion friction wheel 16 is slightly less than 24480 Newton. By adjusting the wrench 12 adjustment pressure adjustment of the screw 10At the position of the ruler value.Finally, the device is turned on the cable to launch the traction work.

Abstract

The invention provides a cable laying traction apparatus which comprises a driving system, a traction force adjusting system, a traction system and an electric interlocking control system. The traction force adjusting system can control pressure between a driven friction wheel and a driving friction wheel, the driving friction wheel and the driven friction wheel can relatively slide when the traction force exceeds a set value, and the electric interlocking control system can set the maximum output traction force as needed and realize interlocking shutdown and effective braking when the traction force exceeds the set value. The cable laying traction apparatus can monitor the traction force in real time, shutdown protection is performed when the traction force exceeds the set value, damage to a cable due to excessive traction force is completely eliminated, and construction efficiency is effectively improved by the aid of a double-speed motor. The construction cost of enterprises is effectively reduced, and the laying quality of the cable is greatly improved.

Description

Technical field [0001] The present invention involves a large -scale cable laying device, which specializes in a cable setting traction device. Background technique [0002] In the process of large -scale cable laying, due to the large cross section of the cable, during the use of mechanical traction, the cable is on the way to move. Due to the role of various resistance, the traction of the cable will suddenly increase.Freshness will damage the cable, and traditional slow rolling can not effectively control the traction. In the process of construction operation, there will often be damage to the cable.At the same time, the rolling speed is not adjustable, which reduces the efficiency of work. Invention content [0003] In order to overcome the lack of existing technologies, the purpose of the present invention is to provide a cable laid traction device, which can monitor the degradation in real time. When exceeding the set value, it can be protected to prevent excessive cables....
