Abstract

The present invention relates to the technical field of retracting devices for a tube winding apparatus, particularly to a slow-moving retraction device for an automatic tube winding apparatus. As there are some disadvantages about the retracting device for the tube winding apparatus in the prior art, for example, the flexible tube or cable swings at random and easily hurts the user, and may be damaged during the retraction, the present invention provides a slow-moving retraction device for an automatic tube winding apparatus, which will slow down the retraction speed, so the flexible tube or cable will not swing at random, and the damage of the tube or cable as well as the personal injury due to the retraction with high speed will be prevented. The slow-moving retraction device includes a fixed sleeve, a rotor, a cover plate, a transmission shaft, a spring and a connector, wherein said rotor and the fixed sleeve are inserted and coupled together by means of a circular wall and a circular groove. Some damping fluid with a certain viscosity is sealed in the seal cavity defined by said cover plate and said fixed sleeve. Said spring and a circular pipe of said connector encase said transmission shaft.

确认本 管上的弹簧固定槽内。 Confirm this The spring in the tube is fixed in the groove.
安装时， 管线自动卷绕器慢回缩装置的固定套上的轴孔与管线自动卷绕器上 的卷簧轴相接， 管线自动卷绕器慢回缩装置的连接件上的固定板与管线自动卷绕 器上的卷绕轮相接。 当拉出软管或缆线时， 管线自动卷绕器上的卷绕轮沿与弹簧 绕向 （即弹簧从其内端朝其外端的绕向） 相反的旋向旋转， 通过固定在其上的连 接件使弹簧松开而未抱紧于传动轴上， 因而带动弹簧在传动轴上空转， 此时， 固 定套与回转体及传动轴之间无相对转动。 当回縮软管或缆线时， 管线自动卷绕器 上的卷绕轮沿与弹簧绕向相同的旋向旋转， 通过固定在其上的连接件使弹簧抱紧 在传动轴上， 此时， 连接件通过弹簧、 传动轴带动回转体一起旋转， 也就是使回 转体相对于固定套转动， 因在固定套与回转体之间设有具有一定粘度的阻尼液体， 故阻碍了传动轴的旋转， 从而使软管或缆线在回缩过程中回缩速度放慢。  During installation, the shaft hole on the fixing sleeve of the automatic rewinding device of the pipeline automatic rewinding device is connected to the coil spring shaft of the automatic winding device of the pipeline, and the fixing plate on the connection member of the automatic rewinding device of the pipeline automatic rewinding device is connected with The winding wheels on the pipeline automatic winder are connected. When the hose or cable is pulled out, the winding wheel on the pipeline automatic winder rotates in a direction opposite to the direction of the spring (that is, the direction of the spring from its inner end to its outer end), and is fixed on it The connecting piece loosens the spring without holding it tightly on the transmission shaft, thus driving the spring to idle on the transmission shaft. At this time, there is no relative rotation between the fixed sleeve and the rotating body and the transmission shaft. When the hose or cable is retracted, the winding wheel on the pipeline automatic winder rotates in the same rotation direction as the spring, and the spring is held on the drive shaft by the connecting member fixed on it. The connecting member drives the slewing body to rotate together through the spring and the transmission shaft, that is, the slewing body rotates relative to the fixed sleeve. Because a damping liquid having a certain viscosity is provided between the fixed sleeve and the slewing body, the rotation of the transmission shaft is blocked. Therefore, the retracting speed of the hose or cable is slowed down during the retracting process.
本发明与现有的管线卷绕器回缩装置相比， 具有使软管或缆线在回縮过程中 回缩速度放慢的特点.。 本发明能消除因软管或缆线回缩速度过快而造成人员伤害 及软管或缆线损坏的隐患。 本发明特别适合作为用于收藏软管的卷管器或用于收 藏缆线的卷线器上的慢回縮装置。 当然， 本发明也适用于其它线材的自动卷绕器， 诸如钢丝卷绕器。 附图说明  Compared with the existing pipeline winder retraction device, the present invention has the characteristics of slowing down the retraction speed of the hose or cable during the retraction process. The invention can eliminate the hidden dangers of human injury and damage to the hose or cable caused by the retracting speed of the hose or cable being too fast. The invention is particularly suitable as a slow retraction device on a hose reel for storing hoses or a reel for storing cables. Of course, the invention is also applicable to automatic winders for other wires, such as wire winders. BRIEF DESCRIPTION OF THE DRAWINGS

图 11示出了本发明的管线自动卷绕器慢回缩装置与一齿轮传动结构相结合的 情况。 当管线自动卷绕器的设计回卷力较大时 （需回缩的软管或缆线很长时往往 需要很大的回卷力）， 为了增加阻尼力矩， 并不直接将本发明慢回缩装置的连接件 6与管线自动卷绕器上的卷绕轮相接， 而是如图 11所示， 可将本发明的慢回縮装 置安装成使其轴线 X与管线自动卷绕器的卷绕轮的轴线 Y相平行 （即不同轴）， 并 且连接件 6通过一减速传动机构， 这里是一对彼此啮合的、 不同半径的传动齿轮 22 和 23， 与卷绕轮接合而传递力矩。 这里的 "减速传动" 是指当从一个部件 （例如 连接件 6) 向另一部件 （卷绕轮） 传递转动时， 所传递的转速减小， 也就是说所传 递的力矩增大。 在这种情况下， 本发明的慢回缩装置的固定套 1可以固定于管线自 动卷绕器中的一固定部分上， 传动齿轮 22同轴地固定安装在连接件 6上， 传动齿 轮 23同轴地固定安装在卷绕轮上， 并且连接件 6上的传动齿轮 22的半径小于卷绕 轮上的传动齿轮 23的半径。 另外， 作为一种等效的方式， 本发明的慢回缩装置也 是安装成使其轴线 X与管线自动卷绕器的卷绕轮的轴线 Y相平行， 传动齿轮 22同 轴地固定安装在连接件 6上， 所不同的仅仅是将慢回缩装置的固定套 1固定连接于 管线自动卷绕器的卷绕轮上， 而将传动齿轮 23与卷绕轮同轴地固定连接于管线自 动卷绕器中的一固定部分上， 这时， 连接件 6试图通过减速传动机构向管线自动卷 绕器的固定部分传递力矩， 传动齿轮 22相当于一行星齿轮随着卷绕轮的旋转而绕 传动齿轮 23的轴线公转。 由于连接件 6上的传动齿轮 22的半径小于卷绕轮上的传 动齿轮 23的半径， 因而能够增强本发明的慢回缩装置对管线自动卷绕器卷绕轮的 回卷动作的阻尼作用， 更有效、 更可靠地达到慢回缩效果。 关于管线自动卷绕器 本身的结构和工作方式， 它们均与以上参照图 1至图 10描述的相同。 FIG. 11 shows a case where the slow retraction device of the pipeline automatic winder of the present invention is combined with a gear transmission structure. When the design of the pipeline automatic winder has a large rewinding force (the rewinding force is often required when the hose or cable to be retracted is very long), in order to increase the damping torque, the invention is not directly slowed down. The connecting member 6 of the shrinking device is connected to the winding wheel on the automatic pipeline winder, but as shown in FIG. 11, the slow retraction device of the present invention can be installed so that its axis X and the The axis Y of the winding wheel is parallel (that is, different axes), and the connecting member 6 transmits a torque through a reduction gear mechanism, here a pair of transmission gears 22 and 23 of different meshes that mesh with each other, and are engaged with the winding wheel. . The "reduction transmission" here means that when rotation is transmitted from one component (such as the connecting piece 6) to another component (winding wheel), the transmitted speed decreases, that is, the transmitted torque increases. In this case, the fixing sleeve 1 of the slow retraction device of the present invention can be fixed to the pipeline. On a fixed part of the moving winder, the transmission gear 22 is coaxially fixed to the connecting member 6, the transmission gear 23 is coaxially fixed to the winding wheel, and the radius of the transmission gear 22 on the connecting member 6 is fixed. It is smaller than the radius of the transmission gear 23 on the winding wheel. In addition, as an equivalent method, the slow retraction device of the present invention is also installed so that its axis X is parallel to the axis Y of the winding wheel of the pipeline automatic winder, and the transmission gear 22 is fixedly mounted coaxially on the connection On the part 6, the only difference is that the fixed sleeve 1 of the slow retraction device is fixedly connected to the winding wheel of the pipeline automatic winder, and the transmission gear 23 and the winding wheel are fixedly connected to the pipeline automatic coil coaxially. On a fixed part of the winder, at this time, the connecting member 6 attempts to transmit a torque to the fixed part of the pipeline automatic winder through the reduction transmission mechanism. The transmission gear 22 is equivalent to a planetary gear that rotates around the winding wheel as the winding wheel rotates. The axis of the gear 23 revolves. Since the radius of the transmission gear 22 on the connecting member 6 is smaller than the radius of the transmission gear 23 on the winding wheel, the damping effect of the slow retraction device of the present invention on the rewinding action of the winding wheel of the pipeline automatic winder can be enhanced. Slower retraction is achieved more efficiently and reliably. Regarding the structure and working mode of the pipeline automatic winder itself, they are the same as those described above with reference to FIGS. 1 to 10.
当然， 本领域技术人员清楚， 上述减速传动机构还可以包括诸如减速链轮传 动机构和减速皮带传动机构等其它的等效机构。  Of course, it is clear to those skilled in the art that the above-mentioned reduction transmission mechanism may also include other equivalent mechanisms such as a reduction sprocket transmission mechanism and a reduction belt transmission mechanism.
