The number of the movable V-shaped wheels 9 is the same as that of the fixed V-shaped wheels 8, and the movable V-shaped wheels are arranged on the platform 4 and are arranged at the side edges of the fixed V-shaped wheels 8.

An intermediate groove 12 is formed between the fixed V-shaped wheel 8 and the movable V-shaped wheel 9, the conductor 10 is limited in the intermediate groove 12, a cycloid speed reducer 2 is arranged on the side edge of the fixed V-shaped wheel 8, a pressing mechanism 6 is arranged on the side edge of the movable V-shaped wheel 9, and the cycloid speed reducer 2 is connected with the fixed V-shaped wheel 8 through a transmission chain 3. The end part of an output shaft of the pressing mechanism 6 is fixedly connected with the movable V-shaped wheel 9. The hold-down mechanism 6 is a cylinder which is fixedly arranged on the side edge of the platform 4. The cycloidal reducer 2 is fixedly installed on a connecting plate 402 on one side of the platform 4, and the connecting plate 402 goes up and down along with the platform 4 to drive the cycloidal reducer 2 and the transmission chain 3 to move up and down. The connecting plate 402 is arranged at the edge of the platform 4, and a certain gap is formed between the inner side wall of the connecting plate 402 and the outer wall of the base 11, so that the connecting plate 402 can move up and down.

The platform 4 is provided with a stroke groove 401, the bottom of the movable V-shaped wheel 9 is provided with a sliding seat 901, the sliding seat 901 and the sliding seat are arranged in the stroke groove 401 and fixedly connected with an output shaft of the cylinder, a bearing is arranged on the sliding seat 901, a mandrel 902 is fixedly arranged in an inner ring of the bearing, the movable V-shaped wheel 9 is sleeved on the mandrel 902, an output shaft of the pressing mechanism extends out, and the sliding seat 901 is pushed to move in the stroke groove.

The fixed V-shaped wheel 8 is fixedly provided with a rotating shaft, the rotating shaft 801 penetrates through the platform 4 and then is in transmission connection with the transmission chain 3, and a bearing is arranged at the joint of the rotating shaft 801 and the platform 4.

The bottom of the platform 4 is provided with a lifting mechanism 5 which drives the platform 4 to move up and down. The bottom of elevating system 5 is provided with base 11, is provided with lift guide post 7 on the base 11, and platform 4 sets up on lift guide post 7 for platform 4 removes along lift guide post 7. The device also comprises a frame 1, wherein the frame 1 is arranged above the platform 4, and a conductor 10 is arranged on the frame 1.

Specifically, when the platform 4 is in a descending state, the conductor 10 is on the frame 1, and when the conductor 10 is aligned between the lower fixed V-shaped wheel 8 and the movable V-shaped wheel 9, the ascending button is started, the ascending mechanism 5 acts to ascend the platform 4, and the fixed V-shaped wheel 8 and the movable V-shaped wheel 9 are covered on the conductor 10. Since the frame 1 is designed to be relatively horizontal, the other conductors 10 do not roll off when the leading conductor 10 is being worked. And then the pressing button is started, the pressing mechanism 6 works, the movable V-shaped wheel 9 moves to the conductor 10, and the conductor 10 is pressed in the V-shaped groove of the two wheels together with the corresponding fixed V-shaped wheel 8. And then the cycloid speed reducing motor 2 is started, power drives the I, II, III and IV fixed V-shaped wheels 8 to rotate through the transmission chain 3, at the moment, the fixed V-shaped wheels 8 and the movable V-shaped wheels 9 tightly press the conductors 10, and the rotating force of the fixed V-shaped wheels 8 drives the movable V-shaped wheels 9 to rotate oppositely through the conductors 10, so that the conveying conductors 10 move forwards and are prepared into a mineral insulated cable copper pipe (cable outer sheath) at the front end, and the assembly is completed. At this time, the lifting mechanism 5 descends to drive the platform 4, the fixed V-shaped wheel 8 and the movable V-shaped wheel 9 to fall back to the lower part of the frame 1, and the movable assembly is finished to prepare for the next moving operation.

The fixed V-shaped wheel 8 and the movable V-shaped wheel 9 are made of nylon materials, have high wear resistance, are not easy to break, and have no toxicity, light weight, excellent mechanical strength and better corrosion resistance; the main chain of the nylon material contains heteroatoms, and the carbon element is less than that of the copper material, and large side groups and polar side groups are not available, so that the nylon material has good flexibility, can form hydrogen bonds, increases intermolecular force, increases glass transition temperature, increases hardness, and is a rigid-flexible binding material. Therefore, when the fixed V-shaped wheel 8 and the movable V-shaped wheel 9 are in pressed contact with the conductor 10 and are in transmission, the noise caused by impact and friction is greatly reduced. Technical data show that the friction coefficient of copper and nylon is 10, which is 0.3 greater than the friction coefficient of metal wheels and conductor 10, and the transmission conductor 10 is more stable.

When the contact surface between the V-shaped groove of the fixed V-shaped wheel 8 and the conductor 10 of the movable V-shaped wheel 9 is too small, the power transmission is too small, so that the conductor 10 moves slowly or unstably; when the contact surfaces of the V-shaped grooves of the fixed V-shaped wheel 8 and the movable V-shaped wheel 9 and the conductor 10 are too large, the conductor 10 is locked by the V-shaped grooves of the fixed V-shaped wheel 8 and the movable V-shaped wheel 9, and the transmission conductor 10 is unstable. According to the design of the V-shaped grooves of the fixed V-shaped wheel 8 and the movable V-shaped wheel 9, the design depth R is 10-20mm and is smaller than the radius of the conductor 10 through calculation and tests according to the specification and size of the conductor 10, so that the conductor 10 can still be partially exposed and is not completely coated to be locked when the fixed V-shaped wheel 8 and the movable V-shaped wheel 9 are pressed; the width L is designed to be 35-55mm and is properly larger than the diameter of the conductor 10, so that most of the conductor 10 is ensured to be in contact with the V-shaped grooves of the fixed V-shaped wheel 8 and the movable V-shaped wheel 9, and only the opening of the V-shaped groove is properly enlarged, so that the fixed V-shaped wheel 8 and the movable V-shaped wheel 9 can conveniently coat the conductor 10, and if the width L is equal to or smaller than the diameter of the conductor 10, the operation is not facilitated; the fixed V-shaped wheels 8 and the movable V-shaped wheels 9 with various specifications are designed to be replaceable, so that the defect of power transmission is avoided, and the fixed V-shaped wheels 8 and the movable V-shaped wheels 9 are more favorable for driving the conveying conductors 10.

This design chooses the cycloidal gear motor 2 of planetary transmission principle for use, and this cycloidal pin tooth engaged novel transmission can reach 1:87 high reduction ratio and high efficiency single-stage transmission of more than 90 percent. The device has the advantages that the power source is only one, the design realizes power transmission through the engagement of four groups of chain wheels and four groups of wheels, uncertain factors such as resistance, energy consumption and the like in the process are more, the motor can be automatically adjusted, and the power transmission is stable.

In the process of rotating, combining and power transmitting and moving the V-shaped wheel set with the conductor, the V-shaped wheel set ensures that the synchronous rotation of the wheel set and the uniform and stable movement of the conductor 10 are ensured, and a stable power technology guarantee is required. The high-strength transmission chain 3 is applied in the design, when the chain is meshed with the sprocket teeth to work, all parts are in rolling and sliding friction, the chain plate is 8-shaped, all sections are close to equal strength, inertia in motion can be reduced, transmission power is 100KW, efficiency is high, h =0.95-0.98, transmission ratio i is not more than 7, the high-strength transmission chain has good impact performance and fatigue performance, tensile strength is 15-30%, almost no sliding exists, the structure is compact under the same condition, axial pressure is small, moving speed is V =2.4m/s, and stable and synchronous four groups of V-shaped wheels I, II, III and IV are guaranteed.
