Description

Technical Field

[0001] This invention relates to the field of hydraulic hose processing equipment technology, specifically to a hydraulic hose sheathing machine and its usage method, which is particularly suitable for automated equipment that automatically sheaths nylon sleeves onto the outside of hydraulic hoses. Background Technology

[0002] Hydraulic power systems are commonly used power systems for existing large-scale engineering equipment. In hydraulic power systems, hydraulic oil is transported through heavy hydraulic pipelines. In order to facilitate the completion of certain specific actions by engineering equipment, some hydraulic pipelines need to use hydraulic hoses to transport hydraulic oil, such as the inlet and return oil pipelines of the luffing cylinder in lifting equipment.

[0003] Adding a nylon sheath to hydraulic hoses enhances their wear and corrosion resistance, thereby extending their service life. Traditional nylon sheath insertion methods rely heavily on manual operation. While this is relatively convenient for shorter, thicker hydraulic hoses, it becomes more difficult, inefficient, and labor-intensive for thinner, longer hoses (e.g., a 15mm outer diameter hose that can reach 7-8m in length). Summary of the Invention

[0004] The purpose of this invention is to provide a hydraulic hose sleeve machine and its usage method. By using this sleeve machine and its usage method, the sleeve work of long hydraulic hoses can be completed quickly and the manual labor intensity is greatly reduced.

[0005] The technical solution adopted by this invention to solve its technical problem is: a hydraulic hose sheathing machine and its usage method, including a support frame, a hose conveying mechanism, a sheath opening and fixing mechanism, a sheathing guide head, and a controller. The hose conveying mechanism includes two sets of clamping components, each of which includes a first transmission belt. The two first transmission belts are arranged opposite each other on the platform of the support frame, and a hose clamping area is set between the two first transmission belts. The width of the hose clamping area in the left and right directions can be adjusted by adjusting the position of the first transmission belts in the left and right directions. One of the two first transmission belts rotates clockwise, and the other rotates counterclockwise. The sheath opening and fixing mechanism is set on the platform and located in front of the hose clamping area. The sheath opening and fixing mechanism is used to open and fix one end of the nylon sheath. The sheathing guide head is used to fit onto one end of the hydraulic hose. The controller can control the operation of the hose conveying mechanism and the sheath opening and fixing mechanism.

[0006] Preferably, the hose clamping area is elongated.

[0007] Furthermore, the hose conveying mechanism also includes a frame support frame and a clamping adjustment assembly. Each clamping assembly further includes a movable slider and a first belt drive mechanism. The frame support frame is fixedly installed at the bottom of the platform. The two movable sliders are slidably installed on the frame support frame from left to right. The first belt drive mechanism is installed on the corresponding movable slider. The first belt drive mechanism is used to drive the rotation of the corresponding first transmission belt. The clamping adjustment assembly is used to adjust the movement of the two movable sliders to move closer or further apart.

[0008] Furthermore, four guide rods arranged in a square pattern are provided inside the frame-shaped support frame. The two movable sliders are slidably sleeved on the four guide rods. The clamping and adjusting assembly includes a first drive motor and a bidirectional lead screw. The bidirectional lead screw is rotatably mounted on the frame-shaped support frame. The two movable sliders are fixedly connected to a corresponding lead screw nut on the bidirectional lead screw. The first drive motor can drive the bidirectional lead screw to rotate, thereby realizing the movement of the two movable sliders moving closer or further apart.

[0009] Furthermore, the first belt drive mechanism includes a first drive shaft and a second drive shaft. The first drive shaft and the second drive shaft are vertically rotatably arranged at the front end and rear end of each of the movable sliders, respectively. A first pulley and a second pulley are respectively arranged at the upper and lower parts of the first drive shaft, and a third pulley and a fourth pulley are respectively arranged at the upper and lower parts of the second drive shaft. A tension pulley is arranged on one side of the upper part of the movable slider, and a second drive motor is arranged on one side of the lower part of the movable slider. The second drive motor is connected to the corresponding second pulley and fourth pulley by means of belt drive. The first drive belt is sleeved between the corresponding first pulley, third pulley and tension pulley.

[0010] Furthermore, a plurality of auxiliary clamping wheels are provided between the first pulley and the third pulley, and the plurality of auxiliary clamping wheels are rotatably mounted on the corresponding movable slider, and the outer sidewall of the auxiliary clamping wheel can fit against the sidewall of the corresponding first pulley.

[0011] Furthermore, the sheath opening and fixing mechanism includes a left half-ring plate, a right half-ring plate, and a linear reciprocating movement mechanism; the left half-ring plate is fixedly disposed on the table, the right half-ring plate is slidably disposed on the table, the left half-ring plate and the right half-ring plate are opposite each other, the linear reciprocating movement mechanism is disposed on the table, and the linear reciprocating movement mechanism is used to drive the right half-ring plate to move left and right and to position itself.

[0012] Furthermore, the hydraulic hose threading machine also includes a hose guiding mechanism, which includes a first limiting component, a guide wheel, and a second limiting mechanism. The first limiting component is located in the right-side area of ​​the center of the table surface and includes two vertically arranged and freely rotatable limiting tubes arranged opposite each other. The guide wheel is rotatably arranged in the rear area of ​​the table surface. The second limiting mechanism includes a hollow square plate, which is vertically fixed on the table surface and located directly behind the hose clamping area. Rotating components are provided on the four side walls of the inner ring of the hollow square plate.

[0013] Furthermore, a nylon-sheathed support platform is provided on the front side of the support frame.

[0014] A method of using a hydraulic hose sleeve machine, comprising the hydraulic hose sleeve machine described above, further comprising the following steps: S1. The staff uses the industrial touch screen installed on the support frame to input the diameter of the hydraulic hose to be transported in the pipe diameter input area; the controller controls the operation of the first drive motor according to the input hydraulic hose diameter and the set program to realize the corresponding width adjustment of the hose clamping area. S2. Using the support of the nylon sheath support platform, the staff straightened and placed the corresponding nylon sheaths in the front area of ​​the left and right semi-circular plates. S3. The staff first passes one end of the corresponding hydraulic hose through the two limit tubes, then around the guide wheel and then into the hollow square plate. After passing out of the hollow square plate, the staff directly inserts the end of the hydraulic hose into the rear area of ​​the hose clamping area. S4. The operator uses an industrial remote control to send a start command to the controller for the second drive motor. When the second drive motor starts, the hydraulic hose begins to move forward under the clamping of the two first transmission belts. When one end of the hydraulic hose passes through the left half-ring plate and the right half-ring plate for a certain length, the operator uses the industrial remote control to send a stop command to the controller for the second drive motor. After the hydraulic hose stops moving, the operator uses the industrial remote control to start the linear reciprocating movement mechanism, causing the right half-ring plate to move towards the left half-ring plate. When the right half-ring plate moves into place, the guide head is placed on the end of the hydraulic hose. Then, one end of the nylon sheath is manually placed on the outside of the end of the hydraulic hose and then on the left half-ring plate and the right half-ring plate. After the end of the nylon sheath is placed, the operator uses the industrial remote control to send a control command to the controller for the linear reciprocating movement mechanism, causing the right half-ring plate to move to the right and stop at the initial position. Then, the left half-ring plate and the right half-ring plate are used to open and fix the end of the nylon sheath. S5. The operator uses an industrial remote control to send a command to the controller to start the second drive motor. After the second drive motor starts, the hydraulic hose moves forward continuously under the clamping of the two first transmission belts. During the movement, the nylon sheath is threaded through. While the hydraulic hose continues to move, the operator constantly observes the threading process. When the end of the hydraulic hose is observed to have emerged from the other end of the nylon sheath, the operator uses the industrial remote control to send a command to the controller to stop the second drive motor. After the second drive motor stops, the operator uses the industrial remote control to send a control command to the controller for the linear reciprocating movement mechanism, causing the right half-ring plate to move towards the left half-ring plate. When the right half-ring plate is in position, the operator simultaneously pulls the ends of the hydraulic hose and the nylon sheath, causing the other ends of the hydraulic hose and the nylon sheath to disengage from the left and right half-ring plates. Then, the operator uses the industrial remote control to send a control command to the controller for the linear reciprocating movement mechanism, causing the right half-ring plate to return to its initial working position, thus completing the threading of the nylon sheath onto one hydraulic hose.

[0015] The beneficial effects of this invention are as follows: The structure of this invention is relatively simple and can be manufactured using existing processing and manufacturing capabilities; the support of the first transmission belt by pulleys and several auxiliary wheels allows for effective contact between the first transmission belt and the hydraulic hose, thereby increasing the friction between the hydraulic hose and the first transmission belt. During the rotation of the two first transmission belts, effective movement and transport of the hydraulic hose between them can be achieved; the opening of the nylon sheath by the left and right semi-annular plates facilitates the smooth entry of the hydraulic hose end into the nylon sheath, while simultaneously fixing the nylon sheath, thus facilitating the insertion process; the bidirectional screw allows for precise adjustment of the hose clamping area width, facilitating effective clamping and transport of the corresponding hydraulic hose, and also facilitating the clamping and transport of hoses of different diameters; during the entire insertion process, only simple manual assistance is required, greatly reducing labor intensity; the hose guiding mechanism guides the movement of the hose, ensuring its smooth entry into the hose clamping area and guaranteeing the successful insertion process.

Detailed Implementation

[0018] The following will describe specific embodiments and appendices. Figure 1-6 The technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of the present invention, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] This invention provides a hydraulic hose sheathing machine (such as...) Figure 1As shown, the system includes a support frame 1, a hose delivery mechanism 2, a sheath opening and fixing mechanism 3, a sheath guide head 4, and a controller. In practical applications, the main frame can be fabricated using several square tubes welded together. A baffle and a door are fixedly installed around the main frame. The square tubes can be high-strength aluminum alloy profiles. The surface of the platform 11 is anodized to form a wear-resistant layer. Adjustable anchor bolts are installed at the four corners of the bottom to adapt to different ground flatness levels. The hose delivery mechanism 2 includes two symmetrically distributed clamping components. Each clamping component includes a first transmission belt 21. The first transmission belt 21 is a synchronous belt made of polyurethane, with a diamond-patterned surface to enhance friction with the hydraulic hose. The two first transmission belts 21 are positioned opposite each other above the platform 11 of the support frame 1. A hose clamping area 211 is provided between the transmission belts 21. In practical applications, to increase the contact length between the first transmission belt 21 and the hydraulic hose, the hose clamping area 211 is elongated. In practical applications, the movement, adjustment, and positioning of the two first transmission belts 21 can be achieved through corresponding movable adjustment components, thereby enabling the adjustment of the width of the hose clamping area 211 in the left-right direction. In practical applications, the size range of the hose clamping area 211 can be set according to the diameter of the existing hydraulic hose 7, such as making the adjustment range of the hose clamping area 211 10mm-50mm. The two first transmission belts 21 can be driven by independent servo motors, one rotating clockwise and the other counterclockwise, and the speed synchronization is achieved through a PLC controller, with the conveying speed adjustable from 0 to 0.The speed can be adjusted within the range of 5m / min to 2m / min to ensure that the hydraulic hose 7 does not deviate or slip during delivery. The sheath opening and fixing mechanism 3 is set on the platform 11 and located in front of the hose clamping area 211. In actual application, the sheath opening and fixing mechanism 3 can be used to open and fix the nylon sheath. After the nylon sheath is opened, it is easy for the end of the hydraulic hose 7 to smoothly enter the nylon sheath. At the same time, the nylon sheath remains fixed during the movement of the hydraulic hose 7, which facilitates the smooth insertion of the sheath. The insertion guide head 4 can be made of stainless steel, with a conical guide part at the front end with a taper of 1:5 and a round rod at the rear end. The round rod can be used to smoothly insert the insertion guide head 4 into the corresponding hydraulic hose. At the end of tube 7, the outer surface of the guide head is coated with Teflon to reduce the resistance during insertion. The controller is an industrial-grade PLC controller equipped with a 7-inch industrial touch screen human-machine interface, which can preset 10 sets of insertion parameters for different specifications of hoses. In the actual insertion process, after inputting the diameter parameter of the hose, the PLC controller can execute the corresponding insertion control program according to the input diameter parameter. For example, when the input hose diameter parameter is 15mm, the PLC controller controls the corresponding actuator to adjust the width of the hose clamping area 211 to 13mm. The width of the hose clamping area 211 is smaller than the corresponding hose diameter parameter, which facilitates the clamping of the hose and thus facilitates the clamping and conveying of the hose. By using the two first transmission belts 21 to clamp and convey the hydraulic hose 7, the hydraulic hose 7 can be continuously moved. During the continuous movement, the guiding effect of the insertion guide head 4 facilitates the smooth movement of the end of the hose within the nylon sheath, thus facilitating the semi-automatic insertion work, thereby improving insertion efficiency and reducing manual labor intensity. .

[0020] Based on the above embodiments, the specific implementation of the hose conveying mechanism 2 is as follows: The hose conveying mechanism 2 further includes a frame support frame 22 and a clamping adjustment assembly. Each set of clamping assemblies further includes a movable slider 231 and a first belt drive mechanism. The frame support frame 22 is welded from Q235B low carbon steel plate with a thickness of 8mm. The two movable sliders 231 are precision machined from 45# steel and can slide relative to each other left and right through two sets of parallel THK linear guide rail pairs or guide rods. The first belt drive mechanism is integrated on the corresponding movable slider 231 and is used to drive the rotation of the corresponding first transmission belt 21. The clamping and adjusting assembly uses a servo motor as the power source to adjust the movement of the two movable sliders 231. Specifically, four square-distributed guide rods 221 are provided inside the frame-shaped support frame 22. The guide rods 211 are made of 40Cr material and are quenched and ground (diameter 20mm, straightness 0.02mm / m). They are fixed to the frame-shaped support frame 22 by bolts through the shoulders at both ends. The two movable sliders 231 are slidably sleeved on the four guide rods 221 with a fit clearance of 0.05-0.1mm. The inner hole of the movable slider 231 is inlaid with a polytetrafluoroethylene bushing. The clamping and adjusting assembly includes a first drive motor 2371 and a bidirectional lead screw 2372. The bidirectional lead screw 2372 is rotatably mounted on the frame support 22 via two SKF precision bearing seats. Two movable sliders 231 are fixedly connected to corresponding lead screw nuts 2373 on the bidirectional lead screw 2372. Specifically, one movable slider 231 is fixedly connected to a left-handed nut, and the other movable slider 231 is fixedly connected to a right-handed nut. The first drive motor 2371 can drive the bidirectional lead screw 2372 to rotate, thereby bringing the two movable sliders 231 closer together or... The moving speed of the movable slider 231 can be adaptively set according to actual needs. By adjusting the position of the two movable sliders 231, the width of the hose clamping area 211 between the two first transmission belts 21 can be adjusted. The first drive motor 2371 is fixedly mounted on one side of the frame support frame 22 through the motor bracket. The first drive motor 2371 can use gear transmission or belt transmission to realize the power transmission with the bidirectional lead screw 2372. The first drive motor 2371 is connected to the PLC controller through PROFINET bus communication and supports position closed-loop control.

[0021] Based on the above embodiments, the specific implementation of the first belt drive mechanism is as follows: The first belt drive mechanism includes a first drive shaft 232 and a second drive shaft 233. The first drive shaft 232 and the second drive shaft 233 are vertically rotatably arranged at the front end and rear end of each movable slider 231, respectively. In actual application, the upper parts of the first drive shaft 232 and the second drive shaft 233 penetrate through the platform 11, and the lower parts are located below the movable slider 231. A first pulley 2321 and a second pulley 2322 are respectively arranged at the upper and lower parts of the first drive shaft 232, and a third pulley 2331 and a fourth pulley 2322 are respectively arranged at the upper and lower parts of the second drive shaft 233. 32. A tensioning wheel 234 is provided on one side of the upper part of the movable slider 231. Specifically, a second support plate 2312 is provided on one side of the movable slider 231, and a support shaft is provided on the second support plate 2312. The support shaft can be moved, adjusted, and positioned on the second support plate 2312. The tensioning wheel 234 is rotatably mounted on the support shaft. A second drive motor 235 is provided on one side of the movable slider 231. Specifically, a first support plate 2311 is provided on one side of the movable slider 231, and the second drive motor 235 is mounted on the first support plate 2311. The second drive motor 235 can be moved, adjusted, and positioned on the first support plate 2311. The second drive motor 235 adopts... The transmission connection with the corresponding second pulley 2322 and fourth pulley 2332 is achieved by belt drive. Specifically, a fifth pulley 2351 is fixedly installed on the output shaft of the second drive motor 235. A second transmission belt 236 is sleeved between the fifth pulley 2351, the second pulley 2322, and the fourth pulley 2332. When the second drive motor 235 starts, the rotation of the first drive shaft 232 and the second drive shaft 233 is achieved through the transmission of the second transmission belt 236. When installing the second transmission belt 236, the second drive motor 235 is first placed in a flexible movement position. The second transmission belt 236 is then sequentially sleeved on the fifth pulley 2351, the second pulley 2322, and the fourth pulley 2332. After the first drive belt 2332 is mounted on the pulley 2332, the position of the second drive motor 235 on the first support plate 2311 is adjusted so that the second drive belt 236 is tensioned. After the second drive belt 236 is tensioned, the second drive motor 235 is fixed. The first drive belt 21 is fitted between the corresponding first pulley 2321, third pulley 2331 and tension wheel 234. When installing the first drive belt 21, the tension wheel 234 is first made to be in a flexible and free adjustment state. After the first drive belt 21 is fitted on the first pulley 2321, third pulley 2331 and tension wheel 234, the position of the tension wheel 234 is adjusted so that the first drive belt 21 is in a tensioned state. Then, the tension wheel 234 is fixed.After the second drive motor 235 starts, the first transmission belt 21 rotates using the transmission action of the first transmission shaft 232 and the second transmission shaft 233. In practical applications, by adjusting the rotation direction of the two second drive motors 235, one first transmission belt 21 rotates counterclockwise, and the other first transmission belt 21 rotates clockwise. In the above embodiment, the pulley is a synchronous pulley, and the second transmission belt 236 is a synchronous belt. Both the first drive motor 2371 and the second drive motor 235 are servo motors.

[0022] When using two first transmission belts 21 to clamp and transport the hydraulic hose 7, in order to improve the contact effect between the two first transmission belts 21 and the hydraulic hose 7, a plurality of auxiliary clamping wheels 238 are provided between the first pulley 2321 and the third pulley 2331. The plurality of auxiliary clamping wheels 238 are rotatably mounted on the corresponding movable slider 231. Specifically, a plurality of support columns are fixedly provided on the upper part of the movable slider 231, and the upper part of the support columns penetrates the table surface 11. The auxiliary clamping wheels 238 are rotatably sleeved on the corresponding support columns, and the outer side wall of the auxiliary clamping wheel 238 can fit against the side wall of the corresponding first pulley 2321. In practical applications, to facilitate the synchronous movement of the first drive shaft 232, the second drive shaft 233, the support shaft supporting the tension wheel 234, and the support column supporting the auxiliary clamping wheel 238 with the corresponding moving slider 231, an elongated hole corresponding to the drive shaft, support shaft, and support column is provided on the table 11. The drive shaft, support shaft, and support column are fitted into the corresponding elongated hole, so that the table 11 does not obstruct the movement of the drive shaft, support shaft, and support column. When the first drive belt 21 is a synchronous belt, to improve the contact effect between the auxiliary clamping wheel 238 and the synchronous belt, a tooth that meshes with the groove of the synchronous belt is provided on the surface of the auxiliary clamping wheel 238.

[0023] Based on the above embodiments, the specific implementation of the sheath opening and fixing mechanism 3 is as follows: The sheath opening and fixing mechanism 3 includes a left half-annular plate 31, a right half-annular plate 32, and a linear reciprocating moving mechanism; the left half-annular plate 31 is fixedly disposed on the platform 11, specifically, the left half-annular plate 31 is fixedly disposed on a first fixed seat 311 disposed on the platform 11, the right half-annular plate 32 is slidably disposed on the platform 11, specifically, a straight guide rail is disposed on the platform 11, a movable support seat 321 is slidably disposed on the straight guide rail, and the right half-annular plate 32 is fixedly disposed on the movable support seat 321. In actual application, in order to facilitate the use of the left half-annular plate 31 and the right half-annular plate 32 to assist in the movement and guidance of the hydraulic hose 7, a guide groove communicating with the interior of the left half-annular plate 31 is provided on the first fixed seat, and similarly, a guide groove communicating with the interior of the right half-annular plate 32 is provided on the movable support seat 321; the left half-annular plate 31 and the right half-annular plate 32 are fixedly disposed on the platform 11. 32 are positioned relative to each other on the left and right sides; the linear reciprocating movement mechanism is mounted on the platform 11 and is used to drive the right half-annular plate 32 to move left and right and to position itself; in practical applications, the linear reciprocating movement mechanism can be a cylinder, an electric cylinder, or a hydraulic cylinder. In this specific embodiment, the linear reciprocating movement mechanism is a first cylinder 33. The specific stroke of the first cylinder 33 driving the right half-annular plate 32 to move can be determined according to the actual inner diameter of the nylon sheath, so as to move the end of the nylon sheath... After being fitted onto the left half-annular plate 31 and the right half-annular plate 32, the left half-annular plate 31 and the right half-annular plate 32 expand and fix the end of the nylon sheath after the right half-annular plate 32 moves into place; in order to increase the coefficient of friction between the outer walls of the left half-annular plate 31 and the right half-annular plate 32 and the nylon sheath, diamond-shaped anti-slip textures are provided on the outer walls of the left half-annular plate 31 and the right half-annular plate 32; the stroke control of the first cylinder 33 can be achieved by using a combination of the existing three-way five-position solenoid valve and the induced check valve.

[0024] Because the hydraulic hose 7 is relatively long, when using two first transmission belts 21 to clamp and transport the hydraulic hose 7, in order to facilitate the smooth entry of the hydraulic hose 7 between the two first transmission belts 21, the sleeve-feeding machine also includes a hose guiding mechanism. The hose guiding mechanism includes a first limiting component, a guide wheel 52, and a second limiting mechanism. The first limiting component is located in the middle right area of ​​the platform 11. The first limiting component includes two vertically arranged and freely rotatable limiting tubes 51, and the two limiting tubes 51 are arranged opposite each other. In order to facilitate the adjustment of the gap between the two limiting tubes 51, one limiting tube 51 is set on the platform 11 and cannot move but can rotate, while the other is set on an elongated hole in the platform 11. A support column is set in the elongated hole, and the bottom of the support column utilizes... The nut is locked onto the platform 11, and the limiting tube 51 is rotatably sleeved on the support column. The two limiting tubes 51 serve as initial guides and prevent the hose from swaying. The guide wheel 52 is rotatably arranged in the rear area of ​​the platform 11. Specifically, the rotation axis of the guide wheel 52 is perpendicular to the platform 11. The guide wheel 52 is used to turn the hydraulic hose 7. The second limiting mechanism includes a hollow square plate 53. The hollow square plate 53 is vertically fixed on the platform 11 and located directly behind the hose clamping area 211. Rotating components 531 are provided on the four side walls of the inner ring of the hollow square plate 53. The rotating component 531 can be a freely rotating round tube or a cylinder composed of multiple bearings. The rotation characteristics of the rotating component 531 help to reduce the wear on the hydraulic hose 7.

[0025] During the sleeve insertion process, if the nylon sheath is placed in a straight line, it will facilitate the smooth movement of the hydraulic hose 7. In order to make the nylon sheath straight, a nylon sheath support platform 6 is set on the front side of the support frame 1. When inserting the sleeve, the operator first straightens the nylon sheath on the nylon sheath support platform 6.

[0026] A method of using a hydraulic hose sleeve machine, comprising the hydraulic hose sleeve machine described in the above embodiments, further comprising the following steps: S1. The operator uses the industrial touch screen 12 installed on the support frame 1 to input the diameter of the hydraulic hose 7 to be transported in the pipe diameter input area; the controller controls the operation of the first drive motor 2371 according to the input hydraulic hose 7 diameter and the set program to realize the corresponding width adjustment of the hose clamping area 211. For example, if the input hose diameter is 15mm, the PLC controller uses the built-in control program to adjust the operation of the first drive motor 2371 so that the width of the hose clamping area 211 is 13mm; this adjustment process realizes high-precision position control through the servo system to ensure that the clamping width matches the hose diameter and avoid the hose slipping or being damaged during transportation; S2. Using the support of the nylon sheath support platform 6, the staff straightened and placed the corresponding nylon sheath in the front area of ​​the left half-ring plate 31 and the right half-ring plate 32. S3. The staff first passes one end of the corresponding hydraulic hose 7 through the two limiting tubes 51, then around the guide wheel 52 and then into the hollow square plate 53. After passing out of the hollow square plate 53, the staff directly inserts the end of the hydraulic hose 7 into the rear area of ​​the hose clamping area 211. S4. The operator uses an industrial remote control to send a start command to the second drive motor 235 to the PLC controller. The industrial remote control is a known mature technology product in the existing technical field. It uses 2.4GHz wireless signal transmission to achieve stable communication with the PLC controller and has good anti-interference ability and response speed. After the second drive motor 235 starts, the hydraulic hose 7 begins to move forward under the clamping of the two first transmission belts 21. When one end of the hydraulic hose 7 has passed through the left half-ring plate 31 and the right half-ring plate 32 for a certain length, usually 100-200mm, the operator uses the industrial remote control to send a stop command to the controller for the second drive motor 235. After the hydraulic hose 7 stops moving, the operator... The operator uses an industrial remote control to start the linear reciprocating movement mechanism (first cylinder 33), causing the right half-ring plate 32 to move towards the left half-ring plate 31. After the right half-ring plate 32 is in place, the guide head 4 is placed on the end of the hydraulic hose 7. Then, one end of the nylon sheath is manually placed on the outside of the end of the hydraulic hose 7, and then placed on the left half-ring plate 31 and the right half-ring plate 32. After the end of the nylon sheath is placed, the industrial remote control sends a control command to the controller to the linear reciprocating movement mechanism, causing the right half-ring plate 32 to move to the right and stop at the initial position. Then, the left half-ring plate 31 and the right half-ring plate 32 are used to open and fix the end of the nylon sheath, providing tension support for subsequent sheathing. S5. The operator uses an industrial remote control to send a command to the controller to start the second drive motor 235. After the second drive motor 235 starts, the hydraulic hose 7 moves forward continuously under the clamping of the two first transmission belts 21. During the movement, the nylon sheath is threaded through. While the hydraulic hose 7 continues to move, the operator constantly observes the threading process to ensure there is no twisting or jamming. When it is observed that the end of the hydraulic hose 7 has emerged from the other end of the nylon sheath, the operator uses the industrial remote control to send a command to the controller to stop the second drive motor 235. After the operation stops, the operator uses an industrial remote control to send a control command to the controller for the linear reciprocating movement mechanism, causing the right half-ring plate 32 to move towards the left half-ring plate 31. When the right half-ring plate 32 is in place, the operator simultaneously pulls the ends of the hydraulic hose 7 and the nylon sheath, causing the other ends of the hydraulic hose 7 and the nylon sheath to disengage from the left half-ring plate 31 and the right half-ring plate 32. Then, the operator uses the industrial remote control to send a control command to the controller for the linear reciprocating movement mechanism, causing the right half-ring plate 32 to return to its initial working position, thus completing the nylon sheath insertion work for one hydraulic hose 7.
