Description

Technical Field

[0001] This utility model belongs to the technical field of wire mesh braiding devices, specifically relating to a built-in wire mesh braiding device for hydraulic supports. Background Technology

[0002] In modern mining, safety and efficiency are perpetual pursuits, and hydraulic supports and their supporting equipment play a crucial role in this process. Hydraulic supports are support devices that use high-pressure fluid as a power source and hydraulic cylinders to achieve functions such as support and movement, making them veritable "safety guardians" of fully mechanized coal mining faces. In underground mining, they not only withstand the enormous pressure of the roof, preventing collapse accidents, but also create a stable space for coal mining operations, greatly improving mining efficiency and safety. They are widely used in coal mines, some metal mines, and special underground engineering projects.

[0003] The core equipment of the internal wire braiding device for hydraulic support hoses is the wire braiding machine, a crucial "behind-the-scenes hero" ensuring the efficient operation of hydraulic supports. Hydraulic supports require the transmission of high-pressure fluid during operation, and the hose, as a key channel for power transmission, must possess high strength and wear resistance. The wire braiding machine, through a precise braiding process, weaves steel wires at specific angles and densities into the inner or outer layer of the hose, forming a strong reinforcing layer. This gives the hose higher pressure resistance, capable of withstanding system pressures of 30-50 MPa or even higher, while simultaneously improving tensile and bending resistance, adapting to the complex working conditions of underground environments characterized by humidity, dust, and frequent support movement. Insufficient hose performance can easily lead to problems such as hose bursts and leaks, causing support malfunctions and threatening operational safety. Therefore, the wire braiding machine is of profound significance to the stable operation of hydraulic supports and safe production in mines, and is an indispensable part of the mining technology system.

[0004] When existing wire braiding machines braid the internal wire frame of hydraulic support hoses, the base of the hydraulic support hose is usually an inner layer of oil-resistant rubber tubing. Due to uneven mixing of raw materials during extrusion molding or the presence of rubber particles and dust residue on the inner wall of the extrusion equipment, the surface of the oil-resistant rubber hose base may adhere to the base surface, resulting in structural defects in the braided layer of the coal mine hydraulic support hose. Under high pressure, it is prone to cracking and leakage, and may even cause equipment failure and safety accidents, shortening its service life and increasing maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to provide a braiding device for the built-in steel wire frame of a hydraulic support hose. This addresses the problem that in existing steel wire braiding machines, the base of the hydraulic support hose is typically an inner layer of oil-resistant rubber tubing. Due to uneven mixing of raw materials during extrusion molding or residual rubber particles and dust from the inner wall of the extrusion equipment adhering to the base surface, the braided layer of the hydraulic support hose in coal mines suffers structural defects. This leads to the hose being prone to cracking and leakage under high pressure, potentially causing equipment failure and safety accidents, shortening its service life, and increasing maintenance costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides the following technical solution: a hose braiding device with an internal steel wire frame for hydraulic supports, comprising a braiding machine body 1, a mounting plate 2 fixedly connected to one side of the feed inlet of the braiding machine body 1, a motor 3 mounted on the top surface of the mounting plate 2, a drive gear 4 connected to the output end of the motor 3, and the other side of the drive gear 4 sleeved in a bearing installed on the inner wall of a protective cover 5. The two side plates of the protective cover 5 are threadedly connected to the top of the mounting plate 2 using bolts 6. A bearing bracket 7 is mounted on the bottom surface of the mounting plate 2, a rotating tube 8 sleeved on the inner wall of the bearing bracket 7, a driven gear ring 9 connected to the surface of the rotating tube 8, and the top surface of the driven gear ring 9 meshing with the drive gear 4. At the bottom of gear 4, the inner wall surface of the rotating tube 8 is connected to a dovetail block 10. The surface of the dovetail block 10 is fitted into a slot opened at the top of the upper brush plate 11. The bottom protrusion of the upper brush plate 11 abuts against the top groove of the lower brush plate 12. The surface of the bearing bracket 7 is connected to a side tube 13. The surface of the side tube 13 is engaged with a rubber rod 14. The other side surface of the rubber rod 14 is connected to a cleaning cloth 15. In this design, the braiding machine body 1 constitutes the main body of the wire braiding machine, and a large number of related components are set in the main body of the wire braiding machine. Since these are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0023] The main model of the steel wire braiding machine in this solution is: GAB series CNC economic steel wire braiding machine.

[0024] In use: When the main body of the wire braiding machine is braiding the internal wire frame of the hydraulic support hose, the oil-resistant rubber hose base is first fed into the braiding area at a uniform speed by the traction device. At the same time, after tension control and straightening, multiple coils of steel wire are braided into a diamond mesh structure by the spindle installed on the circular track through the revolution and rotation motion at an angle of 45°±15° to cover the hose base. During the process, the braiding density and steel wire tension are adjusted in real time by the tension sensor and servo motor. After the braiding is completed, the outer rubber layer is wrapped and vulcanized to form a hose reinforcement layer with high strength, pressure resistance and fatigue resistance.

[0025] Preferably, the inner wall of the protective cover 5 forms a "U"-shaped cavity, the shape and size of which are adapted to the drive gear 4.

[0026] In practical use, the "U"-shaped cavity inside the protective cover 5 can be used to shield the drive gear 4, thereby protecting it and preventing external parts from accidentally touching the drive gear 4 and causing damage.

[0027] Preferably, the rotating pipe 8 is a hollow pipe, and two sets of rectangular through grooves are symmetrically opened on the surface of the rotating pipe 8 on both sides of the driven toothed ring 9.

[0028] In practical use, the hollow groove on the inner wall of the rotating tube 8 facilitates the insertion and fixing of the upper brush plate 11 and the lower brush plate 12, while the rectangular groove opened on it allows the impurities to fall downwards.

[0029] Preferably, a set of dovetail blocks 10 are symmetrically distributed on the inner wall of the rotating tube 8, and the shape and size of the dovetail blocks 10 are adapted to the slots on the surfaces of the upper brush plate 11 and the lower brush plate 12.

[0030] In practical use, the two dovetail blocks 10 connected to the inner wall surface of the tube 8 can be inserted and fixed to the upper brush plate 11 and the lower brush plate 12 respectively, so that the two can abut against the surface of the oil-resistant rubber hose base for cleaning. The dovetail blocks 10 can be made of aluminum alloy or industrial plastic according to the actual use, so as to ensure the connection stability of the dovetail blocks 10 and the upper brush plate 11 and the lower brush plate 12, while preventing the oil stains from causing corrosion.

[0031] Preferably, the upper brush plate 11 and the lower brush plate 12 are both semi-annular structures, and a circular through groove is formed at the intersection of the upper brush plate 11 and the lower brush plate 12.

[0032] In practical use, the upper brush plate 11 and the lower brush plate 12 abut against the surface of the oil-resistant rubber hose substrate to brush away particulate impurities adhering to its surface.

[0033] Preferably, the cleaning cloth 15 has a semi-circular structure, and the two sets of rubber rods 14 and the cleaning cloth 15 are symmetrically distributed on the surface of the bearing frame 7 near the side of the weaving machine body 1.

[0034] In practical use, the rubber rod 14 that engages with the side tube 13 is used to quickly remove and replace the cleaning cloth 15, thereby replacing the contaminated cleaning cloth 15 during production breaks.

[0035] Working principle: When braiding the steel wire frame inside the hydraulic support hose, the traction device on the production line guides the oil-resistant rubber hose substrate through the inner wall at the intersection of the upper brush plate 11 and the lower brush plate 12, then abuts against the cleaning cloths 15 on both sides, and then inserts it into the feed port of the braiding machine body 1 for uniform transmission, thereby using the braiding machine body 1 to braid the steel wire. Simultaneously with the feeding of the oil-resistant rubber hose substrate, the motor 3 is started, driving the drive gear 4 to rotate within the protective cover 5. The rotation of the drive gear 4 drives the meshing driven gear ring 9 to rotate as well, causing the rotating tube 8, which is sleeved between the two bearing brackets 7, to rotate at the bottom of the mounting plate 2. When the rotating tube 8 rotates, the upper brush plate 11 and the lower brush plate 12, respectively inserted into the two dovetail blocks 10 connected to its inner wall surface, abut against the surface of the oil-resistant rubber hose substrate, brushing away the adhering particulate impurities. The upper brush plate 11 and lower brush plate 12 in the design are annularly arranged with bristles made of nylon or polyester material on their inner walls. This avoids damaging the surface of the oil-resistant rubber hose substrate when cleaning impurities. At the same time, the impurities removed by the upper brush plate 11 and lower brush plate 12 fall downwards under gravity through the gaps between the bristles and are discharged from the through groove on the surface of the rotating tube 8. After being cleaned by the upper brush plate 11 and lower brush plate 12, the oil-resistant rubber hose substrate is clamped to the cleaning cloth 15 on both sides of the bearing frame 7 for secondary cleaning. The cleaning cloth 15 is made of polyester fiber dust-free cloth, and its surface is dipped with an appropriate amount of isopropyl alcohol to keep the cloth wet at 60%-70% to avoid dripping. This secondary cleaning removes any residual oil, mold release agent, and other organic contaminants from the surface of the oil-resistant rubber hose substrate, ensuring the cleaning effect of the oil-resistant rubber hose substrate surface and thus ensuring the quality of the finished steel wire frame.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
