Description

Technical Field

[0001] This disclosure relates to the technical field of hydraulic hose winding, and more specifically, to a hydraulic hose winding device with variable diameter and a hydraulic hose winding control method. Background Technology

[0002] Most existing hydraulic hose winding devices are fixed diameter devices, with few technologies incorporating variable diameter functionality. When winding thicker hydraulic hoses, fixed diameter winding devices suffer from excessive pressure on the other side due to the increased tension caused by the larger the hose diameter, making winding difficult. Conversely, increasing the diameter allows the device to wind up even longer hydraulic hoses.

[0003] The previously mentioned case uses a chuck to connect to an arc-shaped plate, achieving a variable diameter by driving the arc-shaped plate to move radially. The radial linear movement of the driving component means that each arc-shaped plate requires a driving component with linear displacement, such as an electric actuator. The disadvantages are that the large number of driving components makes synchronous movement difficult (feedback is needed to ensure synchronous movement), high cost, difficulty in installation, and a small range of variable diameters, resulting in poor practicality.

[0004] Existing devices with variable diameter functions lack control strategies for variable diameters and are all manually adjusted, which cannot automatically set the appropriate diameter for hydraulic oil pipes of different thicknesses. Summary of the Invention

The second motor drives the winding assembly to rotate to achieve adjustment of the winding diameter.

[0007] In some embodiments, the frame includes a base, on which a support plate extending vertically is disposed. The first motor and the winding mechanism are respectively disposed on both sides of the support plate.

[0017] In some embodiments, the arc-shaped plate assembly includes an inner arc-shaped plate and an outer arc-shaped plate arranged at intervals in sequence, the inner arc-shaped plate being arranged corresponding to the groove, and the outer arc-shaped plate being arranged outside the inner arc-shaped plate.

[0018] In some embodiments, an inner connecting plate and an outer connecting plate are respectively provided on the inner side of the inner arc plate and the outer arc plate. The inner connecting plate can be inserted into the corresponding slot, and the outer connecting plate is inserted between two adjacent inner connecting plates. The outer connecting plate is connected to the chuck body by an elastic element.

[0027] The minimum curvature of the hydraulic tube and the minimum winding diameter of the winding mechanism are determined based on the bending tension.

[0028] The target winding diameter of the winding mechanism is determined based on the minimum winding diameter and the length of the hydraulic pipe.

[0030] Once the winding operation is complete, the first motor is stopped and the second motor is started. The second motor drives the variable diameter turntable to rotate via the rotating shaft to adjust the arc plate assembly to a position smaller than the target winding diameter.

[0050] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in still another embodiment,” all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0051] This disclosure provides a variable diameter hydraulic hose winding device, such as... Figures 1-5 As shown, the hydraulic hose winding device can perform the winding operation of hydraulic hoses, and the winding diameter can be adjusted according to the size of different hydraulic hoses, thus making it suitable for winding hydraulic hoses of different specifications. Specifically, the hydraulic hose winding device includes a frame 2, on which a first motor 1 and a winding mechanism 4 are mounted. Here, the first motor 1 and the winding mechanism 4 are mounted on the ground, for example, via the frame 2. The hydraulic hose is sleeved on the outside of the winding mechanism 4. The first motor 1 is used to drive the winding mechanism 4 to perform the winding operation of the hydraulic hose.

[0052] Furthermore, the frame 2 includes a base 21, on which a support plate 22 is disposed. The support plate 22 is disposed in a vertical direction. The first motor 1 is disposed on one side of the support plate 22. The support plate 22 is provided with a connecting hole. The first motor 1 is mounted on the support plate 22 by means of thread and connecting hole. The output shaft 11 of the first motor 1 passes through the support plate 22. The winding mechanism 4 is disposed on the opposite side of the support plate 22.

[0053] Furthermore, a connecting roller 3 is provided between the first motor 1 and the winding mechanism 4. The connecting roller 3 is located between the frame 2 and the winding mechanism 4, so that the output shaft 11 of the first motor 1 passes through the support plate 22 and is connected to the winding mechanism 4 through the connecting roller 3, thereby driving the winding mechanism 4 to move through the connecting roller 3.

[0054] Specifically, the connecting roller 3 has a cylindrical structure with a bottom 31 and an open end 32. The bottom 31 of the connecting roller 3 faces the frame 2, and the open end 32 of the connecting roller 3 faces the winding mechanism 4. The output shaft 11 of the first motor 1 is fixedly connected to the connecting roller 3. Specifically, the output shaft 11 passes through the support plate 22 and is connected to the bottom of the connecting roller 3 through, for example, a first transmission key 5. Thus, the first motor 1 can drive the connecting roller 3 to rotate through the first transmission key 5.

[0055] Furthermore, in this embodiment, the winding mechanism 4 is connected to the connecting roller 3. On the one hand, it can rotate with the connecting roller 3 to realize the winding operation. On the other hand, the winding mechanism 4 can also rotate relative to the connecting roller 3 to realize the adjustment of the winding diameter.

[0056] Specifically, the winding mechanism 4 includes a second motor 6 and a winding assembly. The second motor 6 is located inside the opening end 32 of the connecting roller 3, particularly inside the connecting roller 3. The winding assembly is located outside the opening end 32. Here, the second motor 6 drives the winding assembly to rotate, and the winding diameter is adjusted by the rotation of the winding assembly.

[0057] Specifically, the winding assembly includes a fixed base 7, on which a rotating shaft 13 is provided. One end of the rotating shaft 13 is connected to the fixed base 7, and the other end of the rotating shaft 13 is connected to a variable diameter turntable 11. The fixed base 7 can drive the rotating shaft 13 to rotate, thereby driving the variable diameter turntable 11 to rotate.

[0058] Furthermore, a rotating chuck 8 is movably mounted on the rotating shaft 13. An arc-shaped plate assembly is provided on the outer side of the rotating chuck 8. The hydraulic pipe to be wound is located on the outer side of the arc-shaped plate assembly to achieve winding. Here, the variable diameter turntable 11 can drive the arc-shaped plate assembly to achieve radial movement, and at the same time, the winding diameter can be adjusted through the radial movement of the arc-shaped plate assembly.

[0059] Furthermore, the second motor 6 is disposed on the other side of the fixed chassis 7 and located inside the connecting roller 3. The second motor 6 is fixedly connected to the fixed chassis 7, and the output shaft 61 of the second motor 6 passes through the central hole on the fixed chassis 7 and is connected to the rotating shaft 13 to realize the transmission of power.

[0060] Preferably, the fixed base 7 is fixedly mounted on the open end 32, and the fixed base 7 is provided with a connecting hole. Specifically, one side of the fixed base 7 is connected to the end of the open end 32 of the connecting drum 3 through, for example, the engagement of a thread and a connecting hole, so that the second motor 6 is fixed on the fixed base 7.

[0061] Furthermore, in this embodiment, the rotating shaft 13 is connected to the rotating chuck 8 via a bearing assembly 14, and the bearing assembly 14 is axially fixed by a spring retaining ring 15 and steps on the rotating shaft 13 and the rotating chuck 8.

[0062] Furthermore, the end of the variable diameter turntable 11 is connected to the end of the rotating shaft 13 via a second transmission key 16, thereby driving the rotation of the variable diameter turntable 11 through the rotating shaft 13. The inner surface of the variable diameter turntable 11 is provided with radially arranged grooves 111, which are used to cooperate with the arc-shaped plate assembly to drive the movement of the arc-shaped plate assembly.

[0063] In addition, a limiting disc 12 is provided on the outer side of the variable diameter turntable 11. The limiting disc 12 and the rotating shaft 13 are fixedly connected by, for example, screws. The variable diameter turntable 11 is axially limited by the limiting disc 12.

[0064] Furthermore, the rotating chuck 8 includes a chuck body 81, which is columnar, and a plurality of chucks 82 are arranged radially along the outer surface of the chuck body 81. A groove 83 is provided on the radial end face of the chuck 82, and the groove 83 extends along the length direction of the rotating shaft 13.

[0065] Furthermore, the bottom of the chuck 82 is connected to the fixed base 7, wherein the bottom of the chuck groove 83 is provided with a through hole, and the chuck 82 and the fixed base 7 are connected by screws engaging the through hole.

[0066] The arc plate assembly here is movable relative to the chuck 82. The arc plate assembly includes an inner arc plate 9 and an outer arc plate 10 arranged at intervals. The inner arc plate 9 is arranged corresponding to the groove 111, and the outer arc plate 9 is arranged outside the inner arc plate 9.

[0067] Furthermore, an inner connecting plate 91 and an outer connecting plate 101 are respectively provided on the inner side of the inner arc plate 9 and the outer arc plate 10. Here, the inner connecting plate 91 of the inner arc plate 9 is inserted into the corresponding slot 83, and the outer connecting plate 101 of the outer arc plate 10 is inserted between two adjacent inner connecting plates 91. The outer connecting plate 101 of the outer arc plate 10 is connected to the chuck body 81 by an elastic element.

[0068] Furthermore, a connecting flange 102 is provided at the bottom of the outer arc plate 10, and the connecting flange 102 contacts the surface of the fixed chassis 7 to ensure the stable movement of the outer arc plate 10.

[0069] Furthermore, a connecting boss 92 is provided on the top of the inner connecting plate 91 of the inner arc plate 9. The connecting boss 92 is embedded in the groove 111 of the variable diameter turntable 11 to achieve a limiting connection (the connecting boss is not provided on the top of the outer connecting plate 101 of the outer arc plate 10). The movement of the connecting boss 92 in the groove 111 drives the inner arc plate 91 to move radially, and the radial movement of the inner arc plate 9 drives the outer arc plate 10 to move radially, thereby realizing the adjustment of the winding diameter. Figure 4 , Figure 5 The two states of the winding mechanism 4 are shown, wherein, Figure 4 This indicates that the winding mechanism 4 is winding according to the first diameter. Figure 5 This indicates that the winding mechanism 4 is winding according to the second diameter.

[0070] When a change in diameter is required, the second motor 6 drives the rotating shaft 13 to rotate, and the second transmission key 16 drives the diameter-changing turntable 11 to rotate, thereby causing the inner arc-shaped disk 9 and the outer arc-shaped disk 10 to move radially in a straight line, thus realizing the diameter-changing function during winding.

[0071] This embodiment of the invention enables adjustment of the winding diameter during the winding operation of hydraulic hoses. It is simple to install, easy to implement, and low in cost. Furthermore, this embodiment can automatically determine the target winding diameter based on the diameter of the hydraulic hose to be wound, combined with the minimum winding diameter of the hydraulic hose, thereby minimizing winding resistance caused by hydraulic hose tension.

[0072] A second embodiment of this disclosure provides a winding control method, which employs the winding device described in the above embodiments, such as... Figure 6 As shown, it includes:

[0073] S101, control the operation of the first motor, the first motor drives the winding mechanism to rotate through the connected rotary drum;

[0074] S102, control the first motor to stop and control the second motor to run. The second motor drives the variable diameter turntable to rotate through the rotating shaft to adjust the arc plate assembly to the position corresponding to the target winding diameter.

[0075] The target winding diameter is determined by: determining the bending tension of the hydraulic tube based on the diameter of the hydraulic tube to be wound; determining the minimum curvature of the hydraulic tube based on the bending tension and determining the minimum winding diameter of the winding mechanism; and determining the target winding diameter of the winding mechanism based on the minimum winding diameter and in combination with the length of the hydraulic tube.

[0076] S103, control the second motor to stop and control the first motor to run for winding operation.

[0077] In addition, the winding control method also includes;

[0078] S104, after the winding operation is completed, the first motor is stopped and the second motor is operated. The second motor drives the variable diameter turntable to rotate through the rotating shaft to adjust the arc plate assembly to a position smaller than the target winding diameter.

[0079] The following is a detailed description based on the above control method. The variable diameter hydraulic tube winding device of this embodiment can realize the winding operation. Specifically, the first motor 1 is controlled to rotate, and the first motor 1 drives the connecting drum 3 to rotate. Since the connecting drum 3 is fixedly connected to the winding mechanism 4, the winding mechanism 4 is driven to rotate synchronously. The hydraulic tube to be wound is fixed on the outside of the winding mechanism 4, and the rotation of the first motor 1 is controlled to realize the winding of the hydraulic tube.

[0080] The variable-diameter hydraulic pipe winding device of this embodiment can also achieve the variable-diameter function. Specifically, control the rotation of the second motor 6. The second motor 6 drives the rotation of the rotating shaft 13. The rotating shaft 13 drives the variable-diameter turntable 11 to rotate through the second transmission key 16. Since the inner connecting plate 91 of the inner arc plate 9 is connected to the variable-diameter turntable 11 through the connecting boss 92 at the top and the movement in the axial direction is restricted, the inner arc plate 9 can only move radially. Under the action of the inner arc plate 9 and the spring, the outer arc plate 10 moves radially synchronously with the inner arc plate 9, thus realizing the variable-diameter function of the winding mechanism 4.

[0081] Specifically, there is a wire braided structure inside the hydraulic pipe involved in this embodiment. This makes the bending tension of the hydraulic pipe larger as the diameter of the hydraulic pipe increases. There is a minimum bending tension Tmin for winding the hydraulic pipe. When the curvature k of the hydraulic pipe is less than the minimum curvature kmin, at this time the tension T < Tmin, then the hydraulic pipe is not easy to wind.

[0082] Based on the above principle, the bending tension of the hydraulic pipe to be wound can be determined according to the diameter of the hydraulic pipe to be wound, and then the minimum curvature kmin can be determined, so as to obtain the minimum winding diameter dmin in the variable diameter of the winding mechanism. Then, based on the minimum winding diameter dmin and combined with the length of the hydraulic pipe to be wound, the target winding diameter d for the winding mechanism 4 can be obtained according to the empirical formula.

[0083] On this basis, in an embodiment, during the variable-diameter winding process, the rotation of the second motor 6 is controlled by a closed-loop control algorithm, so that the outer arc plate 10 moves radially to the position corresponding to the target winding diameter, and the second motor 6 is controlled to remain powered on, so that the winding diameter of the winding mechanism 4 remains constant.

[0084] Then, one end of the hydraulic pipe to be wound is passed through the central circular holes of two to three adjacent outer arc plates 10 to prevent the hydraulic pipe from falling off during the winding process, and the first motor 1 is controlled to rotate to wind the hydraulic pipe. When the winding is completed, stop the operation of the first motor 1, control the second motor 6 to rotate, and reduce the winding diameter by driving the movement of the inner arc plate 9 and the outer arc plate 10. Due to gravity, a gap will be generated between the hydraulic pipe and the lower side of the winding mechanism 4. At this time, the wound hydraulic pipe can be taken out.

[0085] The embodiment of the present disclosure can realize the adjustment of the winding diameter during the winding operation of the hydraulic pipe, with simple installation, simple implementation, low cost, and can also automatically determine the target winding diameter for winding according to the diameter of the hydraulic pipe to be wound in combination with the hydraulic pipe to be wound, and minimize the winding resistance caused by the tension of the hydraulic pipe as much as possible.

[0086] Based on the same inventive concept, a third embodiment of this disclosure provides a variable diameter hydraulic tube winding control device, comprising:

[0087] The first control module is used to control the operation of the first motor, which drives the winding mechanism to rotate via a connected roller.

The second motor drives the variable diameter turntable to rotate through the rotating shaft to adjust the arc plate assembly to the position corresponding to the target winding diameter.

[0089] The third control module is used to stop the second motor and control the first motor to run for winding.

[0090] Furthermore, the target winding diameter is determined in the following way:

[0091] The bending tension of the hydraulic hose is determined based on the diameter of the hydraulic hose to be wound up;

[0092] The minimum curvature of the hydraulic tube and the minimum winding diameter of the winding mechanism are determined based on the bending tension.

[0093] The target winding diameter of the winding mechanism is determined based on the minimum winding diameter and the length of the hydraulic pipe.

[0094] Furthermore, the winding control device also includes;
