Technical Field

[0001] This utility model relates to the field of tube winder technology, and in particular to a tube winder braking mechanism. Background Technology

[0002] In many work sites, winding devices for taking out and retrieving tubular tools are commonly used, collectively known as tube winders. Currently, automatic tube or wire winders are mainly available in two forms: spring-driven and motor-driven. Sometimes, when the required length is reached, the tube winder needs to be braked.

[0003] However, existing tube winders have ratchet and pawl braking mechanisms, mainly used for products with spring recovery; there are also structures that use pull-out pins to lock the tube winder in several fixed positions, mostly used for manual tube winders; and there are mechanisms that use screws to adjust the size of the brake ring and tighten the brake disc. However, the above-mentioned braking mechanisms are relatively complex and cumbersome to operate. Therefore, this application proposes a tube winder braking mechanism to solve these problems.

[0028] The hose reel braking mechanism of this application can wind up hoses, wires, or warning tapes that transmit gas or liquid.

[0029] like Figure 1-4 As shown, this application provides a tube winder, including:

[0030] Base 1;

[0031] Reel assembly 2, reel assembly 2 is disposed on base 1;

[0032] The drive device 4 is detachably mounted on one side of the base 1. The output shaft of the drive device 4 is connected to the reel assembly 2 through a connecting component 6. The output shaft of the drive device 4 is inserted into the connecting component 6. The drive device 4 is used to drive the reel assembly 2 to rotate.

[0033] Connecting valve 5 is detachably installed on the other side of base 1, and reel assembly 2 is movably sleeved on connecting valve 5;

[0034] Braking mechanism 8, the braking device is sleeved around the connecting valve 5, and the braking mechanism 8 is used to brake the reel assembly 2.

[0035] In this embodiment, the base 1 is assembled from multiple sheet metal parts, and the drive device 4 can be a pneumatic motor, electric motor, hydraulic motor, spring box, manual crank, etc., which can be replaced according to different drive requirements. The drive device 4 is connected to the base 1 by bolts.

[0036] During installation, first fix the connecting component 6 to the reel assembly 2 with bolts, then fix the connecting valve 5 to the base 1 with bolts, so that one end of the reel assembly 2 is sleeved on the connecting valve 5, then insert the output shaft of the drive device 4 into the connecting component 6, and finally fix the drive device 4 to the base 1 with bolts to complete the assembly. At this time, the drive device 4 will also support the other end of the reel assembly 2.

[0037] During operation, the drive device 4 drives the connecting component 6 to rotate, which in turn drives the reel assembly 2 to rotate. The rotation of the reel assembly 2 will wind the workpiece to be wound.

[0038] This invention modularizes the structure of each component of the tube winder and uses a detachable installation method, which allows for quick assembly of the tube winder. At the same time, the output shaft of the drive device 4 is plugged into the connecting component 6, allowing for quick replacement of the drive device 4 to meet the needs of different working conditions.

[0039] In one embodiment, the reel assembly 2 includes two reels 21 and a cylinder 22. The two reels 21 are located at both ends of the cylinder 22, and the cylinder 22 is coaxially arranged with the two reels 21. A connecting plate 3 is provided inside the cylinder 22. The connecting assembly 6 is detachably connected to the connecting plate 3. The reel 21 near the connecting valve 5 is movably sleeved on the connecting valve 5.

[0040] In this embodiment, the disc 21 is circular. Optionally, the disc 21 may also be a regular polygon or other irregular shape. The cylinder 22 is cylindrical. Optionally, the cylinder 22 may also be a prismatic cylinder. The diameter of the disc 21 is larger than the diameter of the cylinder 22.

[0041] In one embodiment, the connecting valve 5 includes a valve body 51 and a valve core 52. The valve body 51 is detachably connected to the outer wall of the base 1. One end of the valve core 52 is inserted into the valve body 51 through the side wall of the base 1. The disc 21 on the side near the valve core 52 is sleeved on the outer wall of the valve core 52. The other end of the valve core 52 extends into the cylinder 22.

[0042] In this embodiment, the connecting valve 5 is used to connect to an external water supply device and can also support the disc 21. When the disc 21 rotates, it will drive the valve core 52 to rotate synchronously.

[0043] In one embodiment, the connecting component 6 includes an adapter plate 61, a support base 62, and a connecting cylinder 63. The adapter plate 61 and the support base 62 are located on both sides of the connecting plate 3, and the adapter plate 61, the connecting plate 3, and the support base 62 are fixedly connected by bolts. The connecting cylinder 63 is rotatably inserted into the support base 62, and the output shaft of the drive device 4 passes through the connecting cylinder 63 and is inserted into the adapter plate 61.

[0044] In this embodiment, the connecting cylinder 63 is coaxially arranged with the cylinder body 22, and the adapter plate 61 has a groove that matches the output shaft of the drive device 4. The adapter plate 61 can be engaged with the output shaft of the drive device 4. Optionally, the output shaft of the drive device 4 is set to a prismatic shape, and the shape of the groove of the adapter plate 61 matches it. In this way, when the output shaft of the drive device 4 rotates, it will drive the adapter plate 61, the connecting plate 3 and the support base 62 to rotate synchronously, which will drive the cylinder body 22 to rotate for winding. The drive device 4 also supports the winding assembly 2.

[0045] In one embodiment, a reducer 7 is also included. The drive device 4 is connected to the adapter plate 61 through the reducer 7 and the reducer 7 is located inside the cylinder 22. A drive shaft 72 is provided inside the reducer 7. The output shaft of the drive device 4 is connected to one end of the drive shaft 72, and the other end of the drive shaft 72 passes through the connecting cylinder 63 and is inserted into the adapter plate 61.

[0046] In this embodiment, the shape of the output shaft of the reducer 7 matches the shape of the groove of the connecting cylinder 63. The reducer 7 is detachably installed on the inner wall of the base 1 by bolts. The reducer 7 is partially hidden inside the cylinder 22, which can effectively reduce the size of the overall winding device. The reducer 7 is used to reduce the speed of the drive device 4. During installation, the output shaft of the drive device 4 can pass through the side wall of the base 1 and be inserted into the input end of the reducer 7. After the output shaft of the reducer 7 is inserted into the connecting component 6, it can drive the adapter plate 61, the connecting plate 3 and the support base 62 to rotate synchronously, which will drive the cylinder 22 to rotate for winding.

[0047] In addition, the reducer 7 also supports the reel assembly 2. The housing 71 of the reducer 7 is partially inserted into the connecting cylinder 63 together with the drive shaft 72, which can further improve the support strength.

[0048] like Figure 5-6As shown, in one embodiment, the braking mechanism 8 includes a brake disc 81, a brake ring 82, and a control component. The brake disc 81 is connected to and coaxially arranged with the reel assembly 2. The brake disc 81 is sleeved around the connecting valve 5. The brake ring 82 is disposed around the brake disc 81 and partially fits against the outer circumferential surface of the brake disc 81. One end of the brake ring 82 is fixed to the base 1 by a fixing post 83, and the other end of the brake ring 82 is connected to the control component. The control component is used to control the brake ring 82 to brake the brake disc 81.

[0049] In this embodiment, the brake disc 81 is cylindrical and the brake ring 82 is C-shaped. The control component can adjust the pressure of the brake ring 82 on the side wall of the brake disc 81, thereby increasing the friction between the brake ring 82 and the brake disc 81 to achieve the braking effect.

[0050] Specifically, when it is desired to brake the rotating reel assembly 2, the control assembly pulls one end of the brake ring 82, causing the brake ring 82 to contract inward and hug the brake disc 81. At this time, the friction between the brake ring 82 and the brake disc 81 increases, and the brake disc 81 will slowly stop rotating under the action of friction, thereby driving the disc body 21 and the cylinder 22 to stop rotating, achieving the braking effect.

[0051] By setting up a brake disc 81, a brake ring 82, and a control component, when braking, it is only necessary to pull the brake ring 82 to hold the brake disc 81 by the control component to brake the reel assembly 2. Compared with the existing technology, the structure is simple and the operation is convenient.

[0052] In one embodiment, the control component includes a handle 84, a rotating shaft 85, a first connector 86, and a second connector 87. The rotating shaft 85 is rotatably inserted into the base 1 and extends to the inside of the base 1. The handle 84 is connected to one end of the rotating shaft 85 located on the outside of the base 1. One end of the first connector 86 is fixedly connected to the other end of the rotating shaft 85. The other end of the first connector 86 is hinged to one end of the second connector 87. The other end of the second connector 87 is provided with a connecting shaft 88. The other end of the brake ring 82 is sleeved on the connecting shaft 88.

[0053] In this embodiment, the handle 84, the rotating shaft 85 and the first connecting member 86 are fixedly connected. When the handle 84 drives the rotating shaft 85 to rotate, the first connecting member 86 will rotate synchronously around the axis of the rotating shaft 85.

[0054] During operation, the handle 84 drives the rotating shaft 85 to rotate, and the rotation of the rotating shaft 85 drives the first connecting member 86 to rotate synchronously. At this time, the other end of the first connecting member 86 will generate a pulling force on the second connecting member 87, thereby generating a pulling force on the brake ring 82. Under the action of the pulling force, the brake ring 82 hugs the brake disc 81 tightly, which increases the pressure of the brake ring 82 on the brake disc 81, thereby increasing the friction between the brake ring 82 and the brake disc 81, achieving the purpose of braking.

[0055] In one embodiment, the second connector 87 is provided with a limiting portion 871.

[0056] In this embodiment, the second connector 87 is bent away from the rotating shaft 85 to form a limiting part 871. When the handle 84 is rotated, the first connector 86 continuously pulls the second connector 87, causing the brake ring 82 to grip the brake disc 81. When the rotating shaft 85 is located at the bend of the second connector 87, the limiting part 871 of the second connector 87 will lock the rotating shaft 85, thereby keeping the brake ring 82 gripping the brake disc 81, thus fixing the reel assembly 2 and preventing the reel assembly 2 from rotating due to misoperation. When it is necessary to release, it is only necessary to rotate the first connector 86 in the opposite direction by using the handle 84, so that the rotating shaft 85 can disengage from the limiting part 871 of the second connector 87.

[0057] In one embodiment, a friction element 821 is provided on the side of the brake ring 82 near the brake disc 81.

[0058] In this embodiment, the friction element 821 is a rubber block. By providing the friction element 821 on the contact surface between the brake ring 82 and the brake disc 81, the friction between the brake ring 82 and the brake disc 81 can be increased, which can further improve the braking effect.

[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
