Since the impact is a hard impact, it is easy to cause impact vibration damage to the equipment, which has poor safety. In addition, the degree of automation of the linkage travel mechanism is low, which affects the accuracy of the limit. Summary of the invention

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] As attached Figure 1 , Attachment Figure 2 And attached Figure 3As shown, the ship-mounted electric monorail vehicle with flexible impact limit comprises a running track 1, a running mechanism 2 and a lifting device 3. The lifting device 3 is arranged on the running track 1 through the running mechanism 2; the running track 1 is provided with an automatic stopper 4 interlocked with the running mechanism 2 at the beginning and the end of the travel respectively, and the automatic stopper 4 comprises a movable impact plate 5 and a fixed impact seat 6 elastically connected by an elastic pressure detection support part 7, and the running mechanism 2 hits the movable impact plate 5 at the beginning or the end of the travel to compress the elastic pressure detection support part 7. In the utility model, the lifting device 3 is an electric lifting hoist. The utility model uses the automatic stopper 4 to limit the travel of the running mechanism 2 in the elastic pressure detection mode when the running mechanism 2 hits. On the one hand, the impact is changed from the original hard mode to a flexible mode to avoid the equipment from being damaged by the impact vibration. On the other hand, when the impact occurs, the pressure is detected, so as to transmit the braking signal to the running mechanism 2, and the travel limit is performed, so as to realize the automatic and buffered protective travel limit, and improve the limit accuracy and safety.

[0019] In the utility model, the running track 1 is an I-beam installed on the top of the cabin, and the I-beam is fixedly installed by a crane arm or directly welded.

[0020] As attached Figure 3 and attached Figure 4 As shown, the movable impact plate 5 is provided with a guide rod 8, the fixed impact seat 6 is provided with a through cavity 60, the guide rod 8 extends into the through cavity 60, the tail of the through cavity 60 has a plug 9, the elastic pressure detection support 7 includes a stop elastic pressure detection unit 7a elastically connected between the guide rod 8 and the plug 9, the stop elastic pressure detection unit 7a is compressed by the impact of the walking mechanism 2 on the movable impact plate 5, and the interlocking triggers the stop system of the limit walking mechanism 2 to achieve the travel limit of the walking mechanism 2. More specifically, the walking mechanism 2 is an electric walking trolley, and the stop system is the brake system of the electric walking trolley.

[0021] The elastic pressure detection support part 7 also includes a lateral elastic pressure detection part 7b located on the side of the guide rod 8. The guide rod 8 is centrally arranged in the through cavity 60 by supporting a plurality of lateral elastic pressure detection parts 7b uniformly distributed around the guide rod 8. The guide rod 8 is elastically contacted with the inner wall of the through cavity 60 through the lateral elastic pressure detection part 7b. The lateral elastic pressure detection part 7b includes a lateral elastic pressure detection unit 71 and a ball 73 connected to the lateral elastic pressure detection unit 71 through a ball seat 72. A side cavity 80 corresponding to the lateral elastic pressure detection part 7b is opened on the side of the guide rod 8. The ball seat 72 partially extends into the side cavity 80 and is connected to the inner bottom of the side cavity 80 through the lateral elastic pressure detection unit 71. The ball 73 rolls in contact with the inner wall of the through cavity 60 to reduce wear.

[0022] It is worth noting that, as a preference, in the present utility model, the stop elastic pressure detection unit 7a and the lateral elastic pressure detection unit 71 are both pressure sensor springs. Among them, the stop elastic pressure detection unit 7a, on the one hand, changes the impact from the original hard mode to a flexible mode to prevent the equipment from being damaged by impact vibration, and on the other hand, performs pressure detection when the impact occurs, thereby transmitting a braking signal to the walking mechanism 2 to perform travel limit. The lateral elastic pressure detection unit 71 performs posture detection on the walking mechanism 2. The principle is: when a collision occurs to form a limit, if the walking mechanism 2 does not move or deflect, the pressure detection values ​​of the lateral elastic pressure detection units 71 located on each side of the guide rod 8 should be the same. When the walking mechanism 2 moves or deflects, the pressure detection values ​​of the lateral elastic pressure detection units 71 located on each side of the guide rod 8 will be different, thereby judging that the walking posture of the walking mechanism 2 is deflected and needs to be repaired. It should be noted that there are many reasons for the deviation of the walking posture of the walking mechanism 2, such as mechanical wear, bending, etc. Monitoring the walking posture of the walking mechanism 2 can also improve the safety of equipment operation. At the same time, if the walking posture of the walking mechanism 2 deviates too much, it may also cause the collision with the automatic brake 4 to fail, which will cause a greater accident. When the walking posture of the walking mechanism 2 is found to be distorted, timely maintenance can also ensure that the collision with the automatic brake 4 is in an effective state, which is safer.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
