Description

Technical Field

[0001] The utility model relates to the field of brake handles, and particularly relates to a brake handle for a water surface traveling crane in a nuclear power plant hot cell. Background Art

[0002] A traveling crane with a braking function is usually installed above the pool in the nuclear power plant hot cell, and the traveling crane needs to be equipped with a suitable brake handle. The traveling crane can carry the staff to any position above the water surface. The diameter of the handheld part of the brake handle of the traditional water surface traveling crane is often fixed, while the hand sizes of different staff are different. Therefore, the brake handle with a fixed diameter of the handheld part is difficult to adapt to different staff, resulting in poor comfort in using the brake handle. Eventually, it is easy to cause discomfort to the staff when operating the brake handle. Therefore, a brake handle for a water surface traveling crane in a nuclear power plant hot cell is needed to solve the above problems. Content of the Utility Model

[0018] In order to make the technical means, creative features, achieving purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0019] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown in the figure, a brake handle for a water surface traveling crane in a nuclear power plant hot cell includes a handle body 1. Inside the handle body 1, a push rod 6, a brake cable 9, a ratchet seat 10, and a pawl 11 are installed. One end of the handle body 1 is fixedly installed with a cover plate 8. Inside the handle body 1 and on the push rod 6, a thumb button 7 is installed. An installation sleeve structure 2 is fixedly sleeved on the handle body 1. The installation sleeve structure 2 consists of an installation sleeve body 3, installation columns 13, and anti - detachment plates 14. There are several installation columns 13 and they are symmetrically and fixedly installed on the outer wall of the installation sleeve body 3. There are several anti - detachment plates 14 and they are respectively fixedly installed at one end of several installation columns 13. Two limit collar rings 4 are movably installed on the installation sleeve structure 2. Several support structures 5 are also movably installed on the installation sleeve structure 2. The support structure 5 consists of a base rod 15 and a soft pad 16. The soft pad 16 is fixedly installed at the outer end of the base rod 15. The thumb button 7 is used to unlock the brake state. The brake cable 9 is used to transmit the braking force. The cover plate 8 is used to protect the internal structure. The ratchet seat 10 acts as a ratchet and a frame. The pawl 11 cooperates with the ratchet to lock the handle state. The handle body 1 is the main load - bearing member. The push rod 6 can transmit the force of the thumb to the pawl 11 for unlocking. When in use, the operator holds several support structures 5 with the hand, and then presses the thumb button 7 with force. The force is transmitted to the pawl 11 through the push rod 6. At this time, the pawl 11 disengages from the ratchet seat 10, and the handle is in the unlocked state. The operator can rotate the entire handle upward. At this time, the brake cable 9 will wind around the ratchet seat 10, resulting in the braking state of the actuator. When the operator rotates the entire handle downward, the brake cable 9 gradually separates from the ratchet seat 10 and no longer transmits the braking force. At this time, the actuator will change to the released - brake state. When the operator's thumb is released, the push rod 6 will be reset by the internal return spring, and the pawl 11 will also be pushed by the internal spring towards the ratchet, thus entering the locked state again. When it is necessary to adjust the spacing of several support structures 5 so that the operator can comfortably hold several support structures 5, the limit collar rings 4 can be pushed on the installation sleeve body 3. When the limit collar rings 4 move from the middle of the installation sleeve body 3 to both sides, the support structures 5 will be pushed outward by the limit collar rings 4, so that the support structures 5 will move away from the installation sleeve body 3. At this time, the structure formed by several support structures 5 for the operator to hold will be more suitable for operators with larger hand sizes. On the contrary, when the limit collar rings 4 move from both sides of the middle of the installation sleeve body 3 to the middle, the support structures 5 will lose the support of the limit collar rings 4. Then, the support structures 5 can be pushed towards the installation sleeve body 3. At this time, the structure formed by several support structures 5 for the operator to hold will be more suitable for operators with smaller hand sizes. By setting the installation sleeve structure 2, the installation sleeve body 3, the limit collar rings 4, and the support structures 5 on the handle body 1 and making them cooperate with each other, when in use, the staff can hold the brake handle by grasping several support structures 5. Since the spacing of several support structures 5 can be adjusted, it can be adapted to different staff, and ultimately the comfort of the staff operating the brake handle will be improved.

[0020] Further, the sleeve body 3 of the installation sleeve structure 2 is fixedly sleeved on the handle body 1. The limiting sleeve ring 4 is of an annular structure and is movably sleeved on the sleeve body 3 of the installation sleeve. The limiting sleeve ring 4 is located between a plurality of symmetrically arranged installation posts 13. A plurality of inclined grooves 12 are formed on the outer wall of the limiting sleeve ring 4. There is a certain frictional force between the limiting sleeve ring 4 and the sleeve body 3 of the installation sleeve. Therefore, when the movement of the limiting sleeve ring 4 stops and the limiting sleeve ring 4 is accidentally stressed, it will not easily slide on the sleeve body 3 of the installation sleeve. When it is necessary to move the limiting sleeve ring 4 on the sleeve body 3 of the installation sleeve, a rod-shaped tool can be used to push the limiting sleeve ring 4 to move on the sleeve body 3 of the installation sleeve.

[0021] Further, two connection grooves are symmetrically formed at the inner end of the base rod 15 of the support structure 5. The base rod 15 is movably installed on the installation posts 13 and the anti-disengagement plate 14 through the connection grooves. The thickness of the middle part of the base rod 15 is thinner and the thicknesses of both sides are thicker. The base rod 15 is simultaneously located in the inclined grooves 12 formed on the outer walls of the two limiting sleeve rings 4. Since the thickness of the middle part of the base rod 15 of the support structure 5 is thinner and the thicknesses of both sides are thicker, when the limiting sleeve ring 4 moves to both sides on the sleeve body 3 of the installation sleeve, the support structure 5 can be pushed outward by the limiting sleeve ring 4. At this time, the support structure 5 will slide outward on the installation posts 13 and the anti-disengagement plate 14. When the limiting sleeve ring 4 moves toward the middle on the sleeve body 3 of the installation sleeve, the support structure 5 will lose the support of the limiting sleeve ring 4. And because there is a certain frictional force between the support structure 5 and the installation posts 13 and the anti-disengagement plate 14, even if the support of the limiting sleeve ring 4 is lost, the support structure 5 will not slide on the installation posts 13 and the anti-disengagement plate 14. At this time, if it is necessary to move the support structure 5 closer to the sleeve body 3 of the installation sleeve, the support structure 5 can be pushed toward the sleeve body 3 of the installation sleeve.
