Detailed Description
In the prior art, a reel device and a calandria device are adopted to realize the arrangement of the hose on the reel, but in the process, as the hose is continuously wound on the reel, the diameter of the actually wound reel changes, if the rotation proportion of the hose arranger for arranging the hose by the calandria device and the reel is fixed, the hose arranger and the calandria device are not wound or unwound under a constant tightness, namely the root causes of the phenomena of unreeling, winding overlapping and the like can occur.
The design gist of the invention is that after the actual winding diameter of the winding drum after winding the hose is changed, the rotating speed of the winding drum device or the arrangement speed of the hose arrangement device is changed, so that the winding drum device and the hose arrangement device are wound or released under a constant tightness, and finally the phenomenon of unreeling and winding overlapping is avoided, and the constant relationship of the two relationships is the synchronization described in the invention.
In one embodiment, the invention provides a hose reel-up device comprising a reel device 1 and a first encoder 2, and a calandria device 3 and a second encoder 4, a synchronization controller 5;
the spool 11 of the spool device 1 is driven to rotate in the axial direction by the first driving device 12, and can wind the hose in the circumferential direction over a predetermined length;
a first encoder 2 is mounted on the spool device 1 to acquire a first number of pulses per second of the spool device 1;
the screw 31 of the calandria device 3 is driven by the second driving device 32 to rotate along the axial direction, the screw 31 is provided with a hose laying device 33 and moves along the axial direction of the screw 31 so as to match the rotation of the winding drum device 1 to take up and pay off the hose to a preset position to realize winding of the winding drum device 1;
a second encoder 4 is mounted on the comb device 3 to acquire a second number of pulses per second of the screw 31;
the synchronous controller 5 calculates the pulse adjusting ratio according to the first pulse number and the second pulse number, and compares and adjusts the rotating speed of the first driving device and/or the second driving device according to the preset ratio so as to enable the position of the hose layout moving along the axial direction of the screw rod to be matched with the rotation of the winding drum according to the preset relation.
In this embodiment, a specific structure of the hose winding and unwinding device is provided. The primary function of the first encoder 2 is to acquire the rotational speed of the spool 11, in particular by a first number of pulses of 1 second, by the actual applicationWith the result that the total number N of pulses output by the first encoder 2 can be obtained in one cycle of each winding or unwinding of the hose 1 Similarly, the second encoder 4 collects a second number of pulses of 1 second, and the total number of pulses N output by the second encoder 4 2 The number of turns of the gauntlet device 3 during winding or unwinding is converted by the screw 31 into a displacement by which the hose laying device 33 moves horizontally, which essentially represents the horizontal movement speed and displacement of the hose laying device 33. The specific displacement expression is N 2 L/P 2 Where L is the length of the screw 31 and also corresponds to the axial length of the tube 11, let k=n 1 /N 2 Then k=p 1 L/P 2 d, d is the hose diameter, k is the ratio of the adjustment pulses, and the predetermined ratio is denoted as k 0 The purpose of the synchronization is to bring k close to k 0 Due to k 0 Is of a constant value, so that only P is regulated 1 Or P 2 Or co-tuning, as both L and d are constant values. P (P) 1 And P 2 The adjustment of the rotation speed of the winding drum 11 is completed by the rotation speed adjustment of the screw 31, and the screw 31 is a bidirectional screw.
k 0 The principle of the determination method is as follows:
i.e. the initial rotational speed of the spool 11 is related to the rotational speed of the screw 31, at k 0 The phenomenon of unreeling and winding overlapping of the lower winding hose does not occur, which essentially reflects the tightness degree of winding the hose, namely, how much length of hose is wound or unwound, so that the tightness degree can be kept unchanged, and the linear speed of the winding drum 11 and the linear speed of the hose which is rotationally arranged by the screw 31 can be considered to be equal.
The radius of the winding drum device 1 is initially R in the process of pipe collecting 0 With the winding of the hose, the radius increases and decreases with the change of the number of layers of the oil pipe N, and the winding drum device 1 winds the radius:
R N ＝R 0 +Nd；
the linear velocity of the spool 11 is v=ωr N ；
The angular velocity is ω=2n/60, where n is the rotational speed of the spool 11;
therefore, the linear velocity of the spool 11 can also be expressed as: v=2n (R 0 +Nd)/60。
If we keep the winding or unwinding speed of the hose constant, during the winding process, the winding thickness of the drum 11 increases or decreases stepwise, we will give an initial linear speed V 0 The rotational speed formula is as follows:
Figure BDA0004080724510000061
since the linear speeds of the reel device 1 and the pipe arranging device 3 are required to be equal, the rotating speed of the screw 31 can be obtained, and the rotating speed of the reel device 1 changes stepwise along with the increase and decrease of the number of layers of the hose in the whole winding and unwinding process.
The synchronous relationship between the calandria device 1 and the winding drum device 3 is the pulse corresponding relationship of the rotary encoders respectively arranged on the axes thereof, namely, the total number of the pulses sent by the rotary encoders arranged on the two mechanisms is the same in the same time. In the process of pipe winding or pipe unwinding, the total pulse number output by the rotary encoder of the reel device shaft corresponds to the total pulse number output by the rotary encoder of the pipe arranging device, so that the rotation speed of the reel device is adjusted, and the synchronization can be realized.
It should be noted that the axial direction of the spool 11 and the axial direction of the screw 31 are preferably aligned in parallel.
