Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hydraulic hose processing equipment, and in particular to a hydraulic hose unwinding device. Background Technology
[0002] Hydraulic hoses are key components in hydraulic systems that transmit high-pressure fluids. They consist of three parts: an inner rubber layer, a reinforcing layer, and an outer rubber layer. The inner rubber layer, which comes into direct contact with the hydraulic oil, is made of oil-resistant and wear-resistant nitrile rubber or polyurethane to ensure a tight seal. The reinforcing layer is typically made of high-strength steel wire or fiber braiding / winding, providing pressure and explosion resistance and withstanding system pressures (usually tens to hundreds of megapascals). The outer rubber layer is made of materials such as neoprene rubber, possessing aging resistance, corrosion resistance, and wear resistance, protecting the internal structure.
[0003] Hydraulic hoses use unwinding devices primarily to ensure that the hoses can be unwound in an orderly and smooth manner during storage, transportation, and use, avoiding difficulties in retrieval or damage caused by haphazard stacking. However, some existing unwinding devices have design flaws that easily cause hoses to tangle during use. For example, the device lacks effective guiding and limiting structures. During unwinding, the hoses, due to their own elasticity or uneven external tension, are prone to deviating from the intended track and intertwining. The problem of hose tangling not only hinders normal unwinding and reduces work efficiency, but may also damage the hoses due to excessive pulling, affecting their service life and the stable operation of the hydraulic system.

[0027] Example 1:
[0028] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a hydraulic hose unwinding device, including a support frame 1 and a fixed base 2. A driving component 3 is provided on the top of the support frame 1, and a movable component 9 is provided inside the fixed base 2.

[0031] Two sets of movable frames 10 are provided on the outer side of the movable component 9. A fixed ring 23 is fixed between the two sets of movable frames 10 by bolts.

[0032] By setting the movable frame 10, the fixing ring 23 can be easily fixed. By setting the fixing ring 23, the support tube 11 can be easily fixed.

[0033] Example 2:
[0034] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0035] Specifically, the movable component 9 includes a second motor 91 fixed to the inner wall of the fixed base 2. The output end of the second motor 91 is fixed with a reciprocating screw 92 for driving the two sets of movable frames 10 to move back and forth, and the other end of the reciprocating screw 92 is rotatably connected to the inner wall of the fixed base 2.
[0036] By setting a second motor 91, the reciprocating screw 92 can be easily rotated. By setting the reciprocating screw 92, the two sets of moving frames 10 can be easily moved. It should be noted that the inner wall of the fixed base 2 is provided with a cabinet door. When it is necessary to maintain the reciprocating screw 92, the cabinet door can be opened directly to apply the coating to the reciprocating screw 92, which is convenient for maintaining the reciprocating screw 92.
[0037] Specifically, a fixing frame 15 is fixed to the top of the fixing base 2, and two sliding rods are fixed to the inner wall of the fixing frame 15 to improve the stability of the moving frame 10 when it moves.
[0038] By setting the fixed base 2, the fixed frame 15 can be easily fixed. By setting the fixed frame 15, the two horizontally installed sliding rods can be easily fixed. The design of the sliding rods can improve the stability of the moving frame 10 when it moves.
[0039] Specifically, a connecting plate 16 is fixed to one side of the movable frame 10, and two sets of second limit wheels 17 are rotatably mounted on the top of the connecting plate 16 via four sets of fixing blocks.
[0040] By setting the connecting plate 16, the second limit wheel 17 can be rotated easily, and the hose can be guided easily by setting the second limit wheel 17.
[0041] Example 3:
[0042] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0043] Specifically, a slide rail 21 is fixed to the top of the support frame 1, and a mounting plate 22 slides on the outside of the slide rail 21.
[0044] By setting the slide rail 21, the mounting plate 22 can be slid easily. The mounting plate 22 is designed to install the first motor 31. The mounting plate 22 and the slide rail 21 are fastened together with bolts. When the pulley assembly 32 slips, the bolts can be unscrewed, and then the first motor 31 and the mounting plate 22 can be pulled to move on the slide rail 21 to tighten the pulley assembly 32 again. After tightening, the bolts can be screwed into the slide rail 21 through the mounting plate 22 to limit the first motor 31 and prevent the pulley assembly 32 from slipping. It should be noted that the belt in the pulley assembly 32 is a consumable and needs to be replaced after long-term use to avoid breakage.
[0045] Specifically, a first motor 31 is fixed to the top of the mounting plate 22, a pulley set 32 is fixed to the output end of the first motor 31, a coupling 33 is fixed to the shaft of the pulley set 32, and the rotating end of the coupling 33 is fixedly connected to one end of the fixing rod 4.
[0046] The pulley assembly 32 consists of a first pulley, a belt, and a second pulley, a common technique used by those skilled in the art, and will not be elaborated upon here. The first pulley is connected to the output end of the first motor 31 and has a relatively small diameter; the second pulley is connected to subsequent transmission components and has a relatively large diameter. When the first motor 31 starts, its output end drives the first pulley to rotate at high speed. According to the formula v=ωr (v is linear velocity, ω is angular velocity, and r is radius), since the first and second pulleys are driven by the belt, their linear velocities v are equal when the belt does not slip. The first pulley has a larger angular velocity, and the second pulley has a smaller angular velocity. Simultaneously, when the power is constant, P=Tω (T is torque), and the torque T is inversely proportional to the angular velocity ω. Therefore, the pulley assembly 32 achieves both speed reduction and torque increase. A coupling 33 is fixed at the shaft center of the pulley assembly 32, and the rotating end of the coupling 33 is fixedly connected to one end of the fixed rod 4. As a commonly used mechanical transmission component, the coupling 33, in addition to connecting two shafts and transmitting torque and motion, also has the ability to further optimize torque transmission and adapt to certain installation errors in this device. When the pulley assembly 32 drives the coupling 33 to rotate, the special structure inside the coupling 33 (such as the elastic element in a common flexible coupling 33) can absorb and buffer the vibration and impact generated during transmission to a certain extent, allowing the torque to be transmitted to the fixed rod 4 more smoothly. Moreover, the coupling 33 can compensate for axial, radial, and angular misalignments between the two shafts caused by manufacturing and installation errors, ensuring that even with certain deviations, the torque after reduction and torque amplification by the pulley assembly 32 can still be transmitted to the fixed rod 4 efficiently and stably, driving the fixed rod 4 to rotate, thereby ensuring the normal operation of the entire device. By setting up the first motor 31, the pulley assembly 32 can be easily driven to rotate. Then, through the reduction and torque amplification function of the pulley assembly 32 and the stable torque transmission function of the coupling 33, the fixed rod 4 is finally driven to rotate, meeting the working requirements of the device.
[0047] Specifically, a connecting plate 18 rotates on the outside of the scroll 7, and a mounting bracket 19 is fixed on the outside of the connecting plate 18. The mounting bracket 19 is fixed to a support frame 20 by bolts, and one side of the support frame 20 is fixedly connected to one side of the fixed seat 2.
[0048] By setting the connecting plate 18, the stability of the winding roller 7 during rotation can be easily improved. By setting the mounting bracket 19, the connecting plate 18 can be easily supported. By setting the bearing bracket 20, it can be easily connected to the connecting plate 18 by bolts. The cooperation between the connecting plate 18 and the mounting bracket 19 can facilitate the installation and disassembly of the winding roller 8.
[0049] Working principle: When the hose needs to be wound up, first place the hose on two sets of second limiting wheels 17, then pass the hose through multiple sets of first limiting wheels 14 inside the fixing ring 23, then place the hose on the take-up roller 8, and then wind the hose around one of the rods inside the take-up roller 8. Simultaneously, start the first motor 31 and the second motor 91. The rotation of the first motor 31 drives the pulley group 32 to rotate, which in turn drives the coupling 33 to rotate. The rotation of the coupling 33 drives the fixing rod 4 to rotate, which in turn drives the two sets of flanges 5 to rotate. The rotation of the flanges 5 then drives the fixing tube 6 to rotate. The rotation of motor 6 drives the roller 7 to rotate, which in turn drives the take-up roller 8 to rotate. The rotation of the take-up roller 8 tightens the hose. The rotation of the second motor 91 drives the reciprocating screw 92 to rotate, which in turn drives the moving frame 10 to move back and forth. The movement of the moving frame 10 drives the support tube 11, spring 12, fixed column 13, first limit wheel 14, connecting plate 16 and second limit wheel 17 to move. The movement of the support tube 11, spring 12, fixed column 13, first limit wheel 14, connecting plate 16 and second limit wheel 17 can drive the hose to move, preventing the take-up roller 8 from getting tangled during winding and unwinding.
[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
