[0002] During the coal operation process, it is necessary to use a flushing water pipe to dredge or clean the coal operation machinery and the coal operation area. For example, when coal blocks the grille or funnel, it is necessary to use a flushing water pipe to spray high-pressure liquid on the blocked part for dredging; another example is that when there is coal dust or coal sludge on the surface of the operation area, the flushing water pipe can be used to wash the operation area to maintain environmental protection and cleanliness.

[0003] During the above operations using the flushing water pipe, one end of the water pipe is connected to a water source, and the other end is held by hand to flush the target. To meet the operation requirements, the length of the water pipe is short for several meters, and long for dozens of meters or even hundreds of meters. When storing the water pipe, it is usually coiled into a disk shape. During the process of winding the water pipe, the water pipe may be distorted, bent or knotted, thereby affecting the water pressure of the flushing water. Summary of the Utility Model

[0006] The winding mechanism comprises a second reel and a transmission rope wound around the second reel. The second reel is rotatably arranged on the mounting seat and is in transmission connection with the first reel. One end of the transmission rope is fixed on the second reel, and the other end is connected with a counterweight;

[0007] Under the action of its own gravity, the counterweight tensions the transmission rope and makes the second reel have a tendency to rotate in the direction of releasing the transmission rope. The second reel exerts a force or torque on the first reel that tends to rotate in the direction of winding the water pipe.

[0008] Optionally, the rotation central axes of the first reel and the second reel are not collinear; the water pipe automatic winding device further comprises:

[0009] A transmission mechanism is in transmission connection between the second reel and the first reel. When the second reel rotates in the direction of releasing the transmission rope, the second reel can drive the first reel to rotate in the direction of winding the water pipe through the transmission mechanism.

[0010] Further, the transmission mechanism comprises:

[0011] The first driving wheel is coaxially and rotatably fixed to the first reel.

[0012] The second driving wheel is coaxially and rotatably fixed to the second reel, and the first driving wheel is drivingly connected to the second driving wheel.

[0013] Furthermore, the first driving wheel and the second driving wheel are connected by a transmission chain, or the first driving wheel and the second driving wheel are connected by belt drive, or the first driving wheel and the second driving wheel mesh with each other.

[0014] Preferably, the diameter of the first reel is R1, the diameter of the first driving wheel is R2, the diameter of the second driving wheel is R3, and the diameter of the second reel is R4, then (R1 * R3) > (R2 * R4).

[0022] Optionally, a shaft hole is formed on the first reel, and one end of the water pipe passes through the shaft hole and is adapted to connect to a water source.

[0023] Compared with the prior art, the advantages of the present utility model are as follows:

[0024] In this embodiment of the water pipe automatic rewinding device, the principle of rewinding and releasing the water pipe is basically as follows:

[0025] Release of the water pipe: When it is necessary to use the water pipe for flushing, the operator directly pulls and extends the water pipe. Under the action of the counterweight, the second reel applies a force or torque to the first reel that tends to rotate in the direction of winding up the water pipe. Therefore, the water pipe can maintain a taut state and will not bend or knot on the ground.

[0026] Rewinding and resetting of the water pipe: After use, the operator can release the water pipe or move the water pipe by hand towards the direction close to the first reel.

[0039] The present utility model will be further described below with reference to the drawings.

[0040] An embodiment of the present utility model provides a water pipe automatic winding device, which includes a mounting base 1, a first reel 2 and a winding mechanism.

[0041] The first reel 2 is rotatably arranged on the mounting base 1 around its own rotation center axis and is used for winding the water pipe 100. Optionally, a rotating shaft is provided at the rotation center axis of the first reel 2, and the first reel 2 is rotatably mounted on the mounting base 1 through the rotating shaft. The rotating shaft has a shaft hole, and one end of the water pipe 100 passes through the shaft hole. This end can be connected to a water source and used as the water inlet end. Preferably, a universal joint 200 is provided at the water inlet end. After the other end of the water pipe 100 is wound on the first reel 2, it is extended and moved away from the first reel 2 by an operator. This end is used as the water outlet end to flush or water a target object.

[0042] The winding mechanism is connected to the first reel 2. Specifically, the winding mechanism includes a second reel 31 and a transmission rope 32 wound around the second reel 31. The second reel 31 is rotatably arranged on the mounting base 1 and is in transmission connection with the first reel 2. One end of the transmission rope 32 is fixed on the second reel 31, and the other end is connected to a counterweight 33; under the action of its own gravity, the counterweight 33 tensions the transmission rope 32 and makes the second reel 31 have a tendency to rotate in the direction of releasing the transmission rope 32. The second reel 31 applies a force or torque to the first reel 2 that tends to rotate in the direction of winding the water pipe 100. The transmission rope 32 can be a steel wire rope.

[0043] In the water pipe automatic winding device of this embodiment, the principle of winding and releasing the water pipe 100 is basically as follows:

[0044] Releasing of the water pipe 100: When it is necessary to use the water pipe 100 for flushing, the operator directly pulls and extends the water pipe 100. Under the action of the counterweight 33, the second reel 31 applies a force or torque to the first reel 2 that tends to rotate in the direction of winding the water pipe 100. Therefore, the water pipe 100 can maintain a tensioned state and will not bend or knot on the ground.

[0045] Winding and resetting of the water pipe 100: After use, the operator can release the water pipe 100 or move the water pipe 100 by hand in the direction close to the first reel 2. Under the action of the counterweight 33, the second reel 31 rotates in the direction of releasing the transmission rope 32 and drives the first reel 2 to rotate in the direction of winding the water pipe 100, so that the water pipe 100 can be automatically retracted and wound on the first reel 2, thus completing the automatic winding and resetting of the water pipe 100.

[0046] Compared with the method of using a motor to drive the first reel 2 to rotate to reel in the water pipe 100, the automatic water pipe reeling device in this embodiment is more flexible and has a stronger timeliness in the process of reeling in and releasing the water pipe 100, and can automatically reel in and stretch the water pipe 100 anytime and anywhere.

[0047] Example 1

[0048] The rotation center axis of the first reel 2 is not colinear with the rotation center axis of the second reel 31; the automatic water pipe winding device also includes a transmission mechanism 4, which is transmission-connected between the second reel 31 and the first reel 2. When the second reel 31 rotates in the direction of releasing the transmission rope 32, the second reel 31 can drive the first reel 2 to rotate in the direction of winding the water pipe 100 through the transmission mechanism 4.

[0049] The transmission mechanism 4 includes a first transmission wheel 41 and a second transmission wheel 42 which are transmission-connected, wherein the first transmission wheel 41 is coaxially and rotatably fixedly connected to the first reel 2 , and the second transmission wheel 42 is coaxially and rotatably fixedly connected to the second reel 31 .

[0050] Optionally, the first transmission wheel 41 and the first reel 2 are fixedly arranged on the same rotating shaft; the second transmission wheel 42 and the second reel 31 are fixedly arranged on the same rotating shaft, and the two rotating shafts are arranged in parallel.

[0051] As an implementation mode, the first transmission wheel 41 and the second transmission wheel are both sprocket wheels, and the two are connected by a transmission chain 43.

[0052] As another embodiment, the first transmission wheel 41 and the second transmission wheel are both pulleys, and the two are connected by belt transmission;

[0053] As another embodiment, the first transmission wheel 41 and the second transmission wheel are both gears, and the two are meshed with each other.

[0054] In this embodiment, the radius of the first reel 2 is R1, the radius of the first transmission wheel 41 is R2, the radius of the second transmission wheel 42 is R3, and the radius of the second reel 31 is R4, which is set as (R1*R3)>(R2*R4).

[0055] Assume that the angular velocity of the first reel 2 is w1, the angular velocity of the first transmission wheel 41 is w2, the angular velocity of the second transmission wheel 42 is w3, and the angular velocity of the second reel 31 is w4; then w1=w2, w3=w4, w2*R2=w3*R3.

[0056] When the first reel 2 reels or releases a water pipe 100 of length L1, the corresponding released or reeled length of the transmission rope 32 on the second reel 31 is L2, L1 = w1*R1, L2 = w4*R4.

[0057] Then the transmission ratio \(i = L1 / L2=(w1*R1) / (w4*R4)=(w2*R2*R1 / R2) / (w3*R3*R4 / R3)=(R1*R3) / (R2*R4)>1\).

[0058] Therefore, when \((R1*R3)>(R2*R4)\), the transmission ratio \(i>1\), that is, \(L1>L2\), improving the winding transmission efficiency of the water pipe 100.

[0059] Preferably, the radius \(R1\) of the first reel 2 is greater than the radius \(R4\) of the second reel 31; the radius \(R2\) of the first transmission wheel 41 is less than the radius \(R3\) of the second transmission wheel 42.

[0060] The water pipe automatic winding device further includes a fixed pulley 6 provided on the mounting base 1 and a movable pulley 7 mounted on the counterweight 33, and the fixed pulley 6 is arranged higher than the movable pulley 7; one end of the transmission rope 32 far from the second reel 31 is connected to the counterweight 33 or the mounting base 1 after passing around the fixed pulley 6 and the movable pulley 7.

[0061] The number of the fixed pulley 6 and the movable pulley 7 can be set to one, two or more, and those skilled in the art can adjust according to the weight of the counterweight 33.

[0062] Taking the case where both the fixed pulley 6 and the movable pulley 7 are set to two as an example for illustration, as Figure 1 shown, the two fixed pulleys 6 are arranged at intervals, the two movable pulleys 7 are provided, and one end of the transmission rope 32 far from the second reel 31 is sequentially passed around the first fixed pulley, the first movable pulley, the second fixed pulley and the second movable pulley and then fixedly connected to the mounting base 1.

[0063] A guide member 5 is provided at the outlet of the water pipe 100 on the mounting base 1, and a guide groove adapted to slidably cooperate with the outer wall of the water pipe 100 is formed on the guide member 5; one end of the water pipe 100 far from the first reel 2 passes through the guide groove on the guide member 5.

[0064] By providing the guide member 5, it can guide the water pipe 100 during winding or releasing, and at the same time can reduce the resistance of the water pipe 100 during winding and releasing, ensuring the smooth telescopic movement of the water pipe 100.

[0065] Optionally, the guide member 5 is two guide wheels arranged opposite to each other, and the two guide wheels are cooperatively clamped on the outer wall of the water pipe 100. The guide member 5 can also be a sleeve.

[0066] The extending direction of the guide groove is along the tangential direction of the first reel 2.

[0067] The mounting base 1 in this embodiment includes a cabinet body 11 and a mounting beam 12 provided inside the cabinet body 11. The first reel 2, the first transmission wheel 41, the second transmission wheel 42, and the second reel 31 are all located inside the cabinet body 11 and are respectively rotatably provided on the mounting beam 12.

[0068] The cabinet body 11 is used to accommodate and protect the counterweight 33, the reel, and the transmission wheel, preventing the components from being exposed.

In this embodiment, there is no need to provide the transmission mechanism 4 in the embodiment. The radius of the first reel is r1, and the radius of the second reel is r2, where r1 > r2.

[0071] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way.
