The elastic force reel is fixedly installed on the reel base. Below the traveling disk beam is a disk. A protective baffle is installed around the elastic force reel. The protective baffle is fixed on the traveling disk beam to limit the position of the cable, preventing the cable from being damaged by steel during hoisting. It can effectively protect the cable. During the lifting of the traveling crane, the cable is synchronously wound around the elastic force reel. During the lowering of the traveling crane, the cable is synchronously released from the elastic force reel.

[0004] It is desired to provide an improved traveling cable storage device, especially regarding how to reduce the failure rate. Summary of the Utility Model

[0020] The following further describes in detail the specific embodiments of the present utility model with reference to the drawings, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solution of the present utility model and facilitate its implementation.

[0021] Through on-site investigation, it is found that after the spring-type cable reel is removed, the cable will sag by its own gravity. A storage cylinder can be arranged on the hook pulley group housing, and the cable is stored in the storage barrel 1 by the gravity of the cable, avoiding the phenomenon that the cable is broken due to the spring stretching the cable.

[0022] As Figure 1 and Figure 2 shown, the utility model provides a traveling cable storage device, which includes a bracket 9, a storage barrel 1 arranged on the bracket 9, a guiding ring 4, and a driving mechanism connected to the storage barrel 1 and used to control the rotation of the storage barrel 1. A receiving groove 11 for accommodating the cable is arranged in the storage barrel 1. The guiding ring 4 is located above the receiving groove 11, and a through hole for the cable to pass through is arranged on the guiding ring 4. The guiding ring 4 is used to guide the cable, and the receiving groove 11 is an annular groove.

[0023] Specifically, as Figure 1 and Figure 2 shown, when the cable needs to be stored, the storage barrel 1 is located below the cable, the guiding ring 4 is located directly above the receiving groove 11, the driving motor 10 drives the storage barrel 1 to rotate, the rotation center line of the storage barrel 1 is a vertical line. After the cable passes through the guiding ring 4 downward, the cable gradually and automatically falls into the receiving groove 11 of the storage barrel 1 below by its own gravity, and can be coiled in a circular shape in the receiving groove 11. In the utility model, the cable is automatically stored in the storage barrel 1 by its own gravity, and the cable is automatically coiled along the barrel wall. The use of the spring is cancelled, which solves the problem in the prior art that since the cable is stored by relying on the elastic force of the cable reel spring, under the action of the spring, the cable is in a stretched state for a long time, and it is easy to cause the cable to break after long-term use, resulting in the clamping pliers being unable to supply power normally and being out of use, and reduces the failure rate of the traveling cable during use.

[0024] As Figure 1 and Figure 2 shown, the guiding ring 4 is fixedly connected to the cross frame 5, the cross frame 5 is fixedly connected to the mounting bracket 2, one end of the cross frame 5 is fixedly connected to the mounting bracket 2, the guiding ring 4 is installed at the other end of the cross frame 5, the mounting bracket 2 is vertically arranged on the bracket 9, and the mounting bracket 2 is located outside the storage barrel 1. The storage barrel 1 is a cylindrical shape with an open top and a hollow interior. The guiding ring 4 is an annular structure, the central hole of the guiding ring 4 is a through hole, and the axis of the guiding ring 4 is parallel to the axis (i.e., its rotation center line) of the storage barrel 1.

[0025] To facilitate the storage of the cable in the storage barrel 1, the storage device further includes a guiding body 6. The guiding body 6 has a hollow structure and is fixedly arranged in the inner cavity of the storage barrel 1. The guiding body 6 is frustum-shaped. The center of the bottom surface of the guiding body 6 coincides with the center position of the bottom surface of the storage barrel 1. The guiding body 6 and the storage barrel 1 are coaxially arranged. The outer diameter of the guiding body 6 is smaller than the inner diameter of the storage barrel 1. There is a gap between the outer circular surface of the guiding body 6 and the inner circular surface of the storage barrel 1, and this gap forms an annular accommodating groove 11. The width of the accommodating groove 11 is not less than the diameter of the cable. The outer circular surface of the guiding body 6 is a conical surface. The small-diameter end of the guiding body 6 is located below the large-diameter end. The diameter of the small-diameter end of the guiding body 6 is smaller than the diameter of the large-diameter end. The large-diameter end of the guiding body 6 is fixedly connected to the storage barrel 1. The small-diameter end of the guiding body 6 is the top of the guiding body 6, and the large-diameter end of the guiding body 6 is the bottom of the guiding body 6. The taper of the outer circular surface of the guiding body 6 is approximately 85 degrees.

[0026] As Figure 1 shown, the driving mechanism includes a driving motor 10 and a transmission mechanism connected to the driving motor 10. The transmission mechanism is connected to the storage barrel 1.

[0027] In this embodiment, the driving motor 10 is a low-speed motor with a power of 0.8 KW and a rotation speed of 743 r / min, which is matched with the rotation speed of the main hook motor. The transmission mechanism is a belt transmission mechanism 3. One end of the transmission mechanism is fixedly connected to the shaft of the driving motor 10, and the other end of the transmission mechanism is fixedly connected to the bottom of the storage barrel 1 through a transmission shaft. The transmission shaft passes through the bracket 9. By adopting the belt transmission mechanism 3, a flexible connection is formed between the motor and the storage barrel 1. During the operation of the crane, the vibration is relatively large. Adding a flexible connection ensures that the motor and the transmission mechanism are more stable and reliable. When the driving motor 10 operates, the storage barrel 1 is driven to rotate through the belt transmission mechanism 3. As the storage barrel 1 rotates, the cable can pass downward through the guiding ring 4 and then be smoothly coiled into the accommodating groove 11 of the storage barrel 1.

[0028] Preferably, the bottom of the storage barrel 1 is provided with rollable rollers. The bracket 9 is fixedly arranged below the storage barrel 1. The top of the bracket 9 is provided with a chute for accommodating the rollers. The chute is an annular groove coaxial with the storage barrel 1. A plurality of rollers are provided, and the rollers are evenly distributed along the circumference at the bottom of the storage barrel 1. When the storage barrel 1 rotates, the rollers roll along the chute, which can reduce the friction when the storage barrel 1 rotates.

[0029] As Figure 1As shown in the figure, for the convenience of connecting the cable stored in the storage barrel 1 to the clamp power supply, a cable hole 7 is provided on the side of the storage barrel 1, and the cable passes through the cable hole 7 and is connected to the clamp power supply. The specific position of the cable hole 7 on the storage barrel 1 can be designed according to actual requirements. A window 8 for observation and convenient maintenance is also provided on the side of the storage barrel 1, and a transparent cover plate is provided on the window 8. While facilitating the observation of the internal situation and the maintenance of the cable, it can also prevent foreign objects from entering the storage barrel 1, avoiding damage to the cable by external objects.

[0030] Through transformation, the equipment hidden danger of the cable being broken by the cable reel spring is eliminated. The original cable could be used for half a year, and there has been no breakage after the transformation. The original length of one cable was 18 meters, and the cost was about 954 yuan. There are 10 overhead cranes in our company using spring-type cable reels. Calculated in this way, the cable cost can be saved by 954 * 10 * 2 = 19,080 yuan / year. At the same time, the spring-type cable reels can be removed. The annual consumption of cable reels is 5 units * 3,805 = 19,25 yuan / year, and the spare parts cost can be saved by 21,000 yuan / year, with remarkable benefits. After being used for a period of time, it meets the usage requirements of the production site. It is convenient to quickly repair the cable reel when it fails, and the effect is remarkable. After being used for a period of time, it meets the usage requirements of the production site, greatly reducing the labor intensity of maintenance workers.

[0031] The above has made an exemplary description of the present invention in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above concept and technical solution of the present invention are directly applied to other occasions, they are all within the protection scope of the present invention.
