Description

Technical Field

[0001] This utility model belongs to the field of reactor manufacturing technology, specifically relating to a telescopic support cylinder device. Background Technology

[0002] Currently, glass wire is used in the winding of the insulation layer during the production of dry-type air-core reactors. Traditional glass wire cylinder support devices cannot adjust the support radius. This leads to a situation where, at the beginning of winding, sufficient gravity provides enough friction, preventing slippage between the glass wire cylinder and the support device during rotation, and the glass wire has sufficient tension during winding. However, as the glass wire is consumed, gravity decreases, and friction also decreases, causing slippage between the glass wire cylinder and the support device. This makes it impossible to provide appropriate tension to the glass wire during winding, affecting production and requiring the replacement of new glass wire. Consequently, the glass wire on the cylinder cannot be fully utilized, resulting in significant waste. Summary of the Invention

[0003] In order to overcome the above technical problems, the purpose of this utility model is to provide a telescopic support cylinder device, which effectively solves the problem of uneven glass wire tension and large amount of waste that occurs during the glass wire winding process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A telescopic support cylinder device includes a support cylinder 8, an epoxy board 5 is provided at the top of the support cylinder 8, a base 11 is provided at the bottom, and a main shaft 1 passes through the epoxy board 5, the support cylinder 8 and the base 11 in sequence.

[0006] The lower sleeve 6 is installed inside the support cylinder 8. The lower sleeve 6 is located outside the main shaft 1. The lower sleeve 6 is connected to the inner wall of the support cylinder 8 through the support rod 7. The bottom of the lower sleeve 6 is connected to the base 11 through the spring 10.

[0007] The outer wall of the lower sleeve 6 is provided with three sets of upper and lower support rods 7;

[0008] The first set of support rods 7 is connected at one end to the outer wall of the lower sleeve 6 and at the other end to the inner wall of the support cylinder 8;

[0009] One end of the second set of support rods 7 and the third set of support rods 7 are connected to the same point on the outer wall of the lower sleeve 6. The other end of the second set of support rods 7 is connected to the inner wall of the support cylinder 8. The other end of the third set of support rods 7 is connected to the bearing 9, and the bearing 9 is in contact with the surface of the base 11.

[0010] The spindle 1 is fitted with a hexagonal nut 2 with a handle at the top. The upper sleeve 3 is close to the bottom of the hexagonal nut 2. The upper sleeve 3 is close to the upper surface of the epoxy plate 5. The lower surface of the epoxy plate 5 is close to the lower sleeve 6.

[0011] Screw 12 is used to fix the base 11 on the spindle 1 to ensure that the base does not slip relative to the spindle when it rotates with the spindle.

[0012] Vertical grooves are cut into the surfaces of the main shaft 1, upper sleeve 3, epoxy plate 5, and lower sleeve 6, and locating pins 4 are embedded in the grooves. This ensures that the entire assembly does not slip relative to each other when rotating with the shaft.

[0013] The epoxy board 5 has a ring-shaped structure, and the diameter of the inner circle matches the main shaft 1 to ensure that it can pass through the main shaft 1. At the same time, the diameter must be smaller than the outer diameter of the upper sleeve 3 and the lower sleeve 6. A corresponding slot is opened at the position of the positioning pin 4 to fix the position of the epoxy board 5.

[0014] The support rod 7 is connected to the lower sleeve 6 and the support cylinder 8 by a pin, and the support radius of the support cylinder 8 is changed by changing the opening and closing angle of the support rod 7.

[0015] Each set of support rods consists of 7 parts, divided into 3 parts.

[0016] The support cylinder 8 is divided into 3 arc-shaped structures, which form a ring structure and do not contact each other, leaving a gap in the middle. Each piece is connected to the lower sleeve 6 by 3 support rods 7 of each group, with each piece forming a 120° angle in the horizontal direction to ensure that the 3 pieces are concentric when supported.

[0017] The bearing 9 is divided into three parts, each connected to the lower sleeve 6 by three support rods 7 (one in each group), each forming a 120° angle in the horizontal direction to ensure concentricity during support. The beneficial effects of this utility model are:

[0018] This utility model adds a handle to the hexagonal nut, which facilitates disassembly and simplifies operation during actual production. In addition, a spring and bearing are added below the lower sleeve, resulting in a simple structure that better achieves the purpose of saving effort and improving production efficiency.

[0019] The epoxy board is made of epoxy material. Firstly, epoxy material is elastic, which can ensure better fit with the support cylinder when the lower sleeve is pressed down, reducing gaps. Secondly, using epoxy material can reduce the weight of the device itself, increase the fatigue strength of the spindle, and extend its service life.

[0020] The support cylinder features a three-piece design, ensuring optimal support while maintaining the best roundness of the glass fiber cylinder to meet production requirements, and guaranteeing concentricity between the support cylinder and the main shaft. Positioning pins are embedded in the slots of the main shaft, upper sleeve, epoxy board, and lower sleeve to prevent slippage when the retractable support rotates with the shaft. This provides suitable tension to the glass fiber during winding, facilitating production, reducing waste, and increasing raw material utilization. The retractable support cylinder device can accommodate cylinders of different sizes without requiring any component replacement, offering strong adaptability and reducing production costs.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 2 As shown, a telescopic support cylinder device includes a main shaft 1, with a hexagonal nut 2 with a handle fitted at the top of the main shaft 1. Below the hexagonal nut 2 is an upper sleeve 3, below the upper sleeve 3 is an epoxy plate 5, and below the epoxy plate 5 is a lower sleeve 6. The lower sleeve 6 is connected to a support cylinder 8 and a bearing 9 via a support rod 7. The lower sleeve 6 is connected to a base 11 via a spring 10. Screws 12 are used to fix the base 11 on the main shaft 1. Positioning pins 4 are embedded in the slots of the main shaft 1, the upper sleeve 3, the epoxy plate 5, and the lower sleeve 6.

[0027] The support rod 7 is divided into 3 groups of 3 rods each. Two rods in each group are used to connect to the support cylinder 8, and one rod is used to connect to the bearing 9.

[0028] The support cylinder 8 is divided into 3 pieces, each of which is connected to the lower sleeve 6 by 3 sets of support rods 7 (2 of each set), each at a 120° angle in the horizontal direction, to ensure that the 3 pieces are concentric when supported.

[0029] The bearing 9 is divided into 3 parts, each of which is connected to the lower sleeve 6 by 3 sets of support rods 7 (one of each set), each at a 120° angle in the horizontal direction, to ensure that the 3 parts are concentric when supported.

[0030] The working principle of this utility model:

[0031] The glass fiber spool is fitted onto the support cylinder 8, covered with the epoxy board 5, and then the upper sleeve 3 is fitted on. The hexagonal nut 2 with a handle is screwed onto the main shaft 1. The downward pressure distance of the upper sleeve 3 and lower sleeve 6 is controlled by adjusting the stroke of the hexagonal nut 2 with the handle, thereby changing the opening angle of the support rod 7. The support rod 7 is connected to the lower sleeve 6 and the support cylinder 8 by a pin. The support radius of the support cylinder 8 is changed by altering the opening angle of the support rod 7, thus achieving a tight fit between the inner wall of the glass fiber spool and the support cylinder 8. The bearing 9 and spring 10 can achieve the purpose of saving effort during the entire telescopic support process. The entire telescopic support part sits on the base 11 and is fixed to the main shaft 1 by screws 12. The main shaft 1, upper sleeve 3, epoxy board 5, and lower sleeve 6 are slotted and embedded with positioning pins 4 to avoid relative sliding between the telescopic support part and the main shaft 1. This ensures that the whole does not slide relative to the main shaft 1 when rotating, and solves the problem of uneven glass wire tension and low utilization rate and waste caused by slippage during glass wire winding.
