[0002] The crane braking system is an important part of the crane. It is mainly responsible for realizing accurate and reliable parking and braking functions during the operation of the crane, ensuring the safety and stability of the crane and its load. Regular detection and self-diagnosis of the braking system can timely detect and eliminate potential safety hazards and ensure the safe operation of the crane.

[0003] After retrieval, the publication number CN204628380U discloses a crane braking system detection and self-diagnosis system. This system device sets a braking detection system on the crane brake and transmits the detection information to the industrial control computer. The industrial control computer performs analog-to-digital conversion, data storage, data statistics, and data analysis. For the detected fault information, it is timely displayed and an alarm message is sent, enabling maintenance personnel to conduct timely and effective troubleshooting and repair according to the displayed relevant fault information, avoiding the malfunctioning operation of the braking system and eliminating the potential safety hazards of the crane braking system.

[0004] When the above system operates, multiple sensors need to be connected to the industrial control computer. In the prior art, the sensors and the industrial control computer are connected through communication cables. When the position of the crane braking system is relatively high from the ground, the required communication cables are relatively long, and after the communication cables are connected, they are randomly placed, which easily causes the cables with similar frequencies to be wound and contacted, resulting in interference with communication information, reducing the detection accuracy. At the same time, the cables are randomly wound and are not convenient for timely troubleshooting and repair during maintenance. Summary of the Utility Model

A baffle is fixedly sleeved on the rod wall of the rotating rod. The communication cable is fixedly wound around the rod wall of the rotating rod. A positioning and limiting mechanism for restricting the winding of the communication cable is arranged between the baffle and the positioning gear.

[0010] Preferably, the positioning and limiting mechanism includes two symmetrically arranged insertion rods. The insertion rods are slidably arranged inside the baffle. The rod walls of the insertion rods are inserted into the tooth grooves of the positioning gear. A spring is sleeved on the rod walls of the insertion rods. Two ends of the spring are respectively fixedly connected with the insertion rods and the baffle.

[0011] Preferably, a support frame is fixedly arranged at one end of the two insertion rods away from the industrial control computer. A connecting rod is rotatably arranged inside the support frame. A pull ring is fixedly arranged between the two connecting rods.

[0012] Preferably, a placement groove is formed on the outer wall of the baffle. The connecting rod and the pull ring are arranged inside the placement groove.

[0013] Furthermore, an opening groove is formed on the groove wall of the placement groove.

[0025] An embodiment of the present utility model discloses a detection and self - diagnosis device for a crane braking system.

[0026] Embodiment 1

[0027] The present utility model provides a detection and self - diagnosis device for a crane braking system as shown in Figures 1-3 Figure, which includes an industrial control computer 1 and a plurality of connection ports 2 provided on the side wall of the industrial control computer 1. A connector 3 is inserted into the connection port 2, a communication cable 4 is connected to the end of the connector 3, and a detection sensor 5 is connected to the end of the communication cable 4;

[0028] A plurality of positioning gears 6 are fixedly provided on the outer wall of the industrial control computer 1. A rotating rod 7 is rotatably provided on the outer wall of the positioning gear 6. A baffle 8 is fixedly sleeved on the rod wall of the rotating rod 7. The communication cable 4 is fixedly wound around the rod wall of the rotating rod 7.

[0029] Before detecting the braking system of the crane, connect multiple detection sensors 5 to relevant components inside the braking system. Then, insert and mate the connector 3 at the other end of the communication cable 4 with the connection port 2 of the industrial control computer 1. Subsequently, the operating status of the internal components of the braking system can be monitored in real time through the detection sensors 5, and the monitoring signals are transmitted into the industrial control computer 1. Immediately afterwards, the signals are sorted out by the industrial control computer 1 and transmitted into the corresponding alarm terminal, thereby completing the detection and self-diagnosis of the crane braking system. After the communication cable 4 is connected, by rotating the rotating rod 7, the rotating rod 7 winds the redundant communication cable 4, minimizing the risk of electromagnetic interference caused by the chaotic winding of the communication cable 4 and ensuring the stability of the detection signal transmission. At the same time, the coiled cable facilitates the quick positioning and maintenance of the communication cable 4 in the subsequent process, improving the usage effect of the detection device.

[0030] Embodiment 2

[0031] Based on Embodiment 1, in Embodiment 2, in order to determine the position of the rotating rod 7 after the communication cable 4 is wound by the rotating rod 7, as Figures 2-3 shown, a positioning and limiting mechanism for restricting the winding of the communication cable 4 is provided between the baffle 8 and the positioning gear 6. The positioning and limiting mechanism includes two symmetrically arranged insertion rods 9. The insertion rods 9 are slidably arranged inside the baffle 8, and the rod walls of the insertion rods 9 are inserted into the tooth grooves of the positioning gear 6. A spring 10 is sleeved on the rod walls of the insertion rods 9, and both ends of the spring 10 are fixedly connected to the insertion rods 9 and the baffle 8 respectively.

[0032] Before winding the communication cable 4, the two insertion rods 9 can be pulled to stretch the spring 10 by the insertion rods 9 and pull the insertion rods 9 out of the tooth grooves of the positioning gear 6, enabling the rotating rod 7 to rotate stably to wind the communication cable 4. After the winding is completed, the insertion rods 9 can be released, and under the elastic recovery of the spring 10, the insertion rods 9 are inserted into the tooth grooves on the side of the positioning gear 6 to fix the position of the rotating rod 7, completing the winding and positioning work of the communication cable 4.

[0033] Embodiment 3

[0034] Based on Embodiment 2, in Embodiment 3, in order to simultaneously perform the lifting and releasing operation on the two insertion rods 9, as Figure 2 shown, a support frame 11 is fixedly provided at one end of the two insertion rods 9 away from the industrial control computer 1. A connecting rod 12 is rotatably arranged inside the support frame 11. The support frame 11 is U-shaped and is rotatably matched with the connecting rod 12 through a bearing. A pull ring 13 is fixedly provided between the two connecting rods 12. A placement groove 14 is opened on the outer wall of the baffle 8. The connecting rod 12 and the pull ring 13 are arranged in the placement groove 14, and an opening groove 15 is opened on the groove wall of the placement groove 14.

[0035] Through the setting of the placement groove 14, the position of the pull ring 13 can be determined. At the same time, with the rotational cooperation of the pull ring 13, the connecting rod 12 and the support frame 11, when the pull ring 13 is pulled, the two insertion rods 9 can move simultaneously, improving the operational convenience of the device.

[0036] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
