Description

Technical Field

[0001] The patent of this invention belongs to the field of non-standard equipment manufacturing, and relates to a production and manufacturing equipment for twisted-type barbed pole wire, which is suitable for the production and manufacturing of twisted-type barbed pole wire. Background Art

[0002] In actual engineering applications, the electrostatic precipitator and coke remover may form a corona closure phenomenon due to factors such as dust concentration in flue gas and operating environment in some engineering projects. That is, the electric field near the cathode line is reduced to the initial value of the corona, which greatly reduces the corona current and even approaches zero, making the electrostatic precipitator and coke remover lose its dust removal and coke removal function. Solving the corona closure problem has become an urgent problem in the industry.

[0003] Measures to improve and weaken corona closure include: reducing the dust concentration in flue gas; reducing the wind speed in the electric field; changing the corona wire to a thorn wire that is easy to capture high-concentration dust, etc. After the dust removal and decoking device project is completed, the equipment parameters are finalized, and due to site limitations, it is difficult to carry out large-scale upgrades to reduce the dust concentration in flue gas. Even if there are conditions for transformation, huge investments will be required, such as adding a pre-treatment dust collector, and the transformation construction period is long, the return on investment is disproportionate, and the transformation effect cannot be well guaranteed, so this plan is rarely accepted by the market.

[0004] In order to solve the problems existing in the prior art, the applicant has proposed a corona-enclosed cathode wire for electrostatic dust removal and decoking. The application of the cathode wire in the electrostatic dust removal and decoking device not only solves the problem of corona closure, but is also a highly efficient and low-investment cathode wire for increasing current density. However, in the field of production and manufacturing, there is no non-standard equipment for manufacturing such a barbed pole wire. If it is made manually, the efficiency is low and the cost is very high. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the applicant proposes a production and manufacturing device for twisted barbed wire, which is suitable for the production and manufacturing of twisted barbed wire. It solves the problem of manual production, and the whole process from the loading of barbed wire is completed by the production and manufacturing device for twisted barbed wire, which improves efficiency and ensures product quality.

[0007] Among them, the barb twisting assembly and the automatic threading assembly are installed in the middle section of the platform frame component, and are used to wrap the steel wire in the shape of a twist on the barb pole line. The horizontal movement distance of the platform frame assembly is slightly longer than the length of the barb pole line, and the horizontal movement distance of the platform frame assembly is set between 4.5 meters and 6.2 meters. The barb twisting assembly twists two steel wires that have been cut to a set length on the barb pole line in a twisted shape, and adjusts the tightness of the twisted steel barbs on the barb pole line. The end adjustment assembly is used to adjust the axial angle of the barb pole line. The automatic threading assembly pushes the steel wire that has been cut to a set length into the barb twisting assembly through a cylinder, and can return to the starting position when waiting for the barb twisting assembly to start twisting the barb, and can also return to the starting position to ensure that there is no interference with the barb twisting assembly. The control component also includes power management for the production and manufacturing equipment of the twisted barb pole line. Preferably, the platform frame assembly includes a frame, guide rails, racks, gears, a horizontal carrier, a platform frame assembly motor and a reducer; when the platform frame assembly motor is working, the gears rotate, and the entire horizontal carrier is driven to perform horizontal linear motion on the frame through the action of the rack, and the movement range of the horizontal carrier is determined according to the length of the barb pole line.

[0008] Preferably, the end adjustment components are installed at both ends of the frame of the platform frame component, with one end adjustment component installed at each end, and the distance between the two end adjustment components is set between 5.2 meters and 6.7 meters.

[0009] Furthermore, the end adjustment assembly includes a lower base plate, a sliding component, a box seat, a box body component, an end adjustment assembly motor, a turntable and a hanging column; the sliding component is fixed on the lower base plate, the box seat is connected to the sliding component, the box body component is installed on the box seat, the end adjustment assembly motor and the turntable are respectively installed on both sides of the box body component, the hanging column is fixed on the turntable, and the end adjustment assembly motor rotates through the box body component to drive the turntable to rotate, thereby rotating the hanging column; the rotation angle is controlled between positive and negative 120 degrees.

[0010] When using the manufacturing equipment for the twisted barbed wire of the present invention, the operator only needs to manually hang the steel wire rope used for making the barbed wire on both ends of the equipment, and the automatic threading assembly equipped with steel wires of specific specifications will simultaneously fill the two steel wires into the twisting component. After the twisting component twists the steel wires on the steel wire rope in the shape of a twist, the platform frame assembly sends the twisting component to the next position, and then the end adjustment assembly rotates the steel wire rope axially by a certain angle, and then each assembly of the equipment repeats the two processes of filling wire and twisting barbed wire. The above operations are repeated continuously until the barbed wire is made after all the processes are finally completed, and the operator manually removes the barbed wire.
