[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1-Figure 4 A windproof zipper fixing device for a trolley of a ship loader comprises a trolley steel structure 1 and a zipper body 2. A square tube 3 is fixedly connected to the bottom surface of the trolley steel structure 1. A lock bracket assembly 4 is fixedly connected to the bottom end of the square tube 3. A proximity switch 5 is built into the lock bracket assembly 4. A lock head 6 is fixedly connected to one end of the zipper body 2. One end of the lock bracket assembly 4 is fixedly connected to the lock head 6.

[0025] The lock head 6 comprises a connecting block 61 , both ends of which are threadedly connected to limit blocks 62 , each of which is a U-shaped structure, and a movable pin 63 is penetrated and connected to the side wall of each limit block 62 .

[0026] One of the limit blocks 62 is fixedly connected to the zipper body 2 via a movable pin 63 .

[0027] The locking bracket assembly 4 includes side plates 41 symmetrically fixedly connected to the side walls of the bottom end of the square tube 3 , and a mounting cross plate 42 is fixedly connected between the two side plates 41 .

[0028] The other limiting block 62 is fixedly connected to the two side plates 41 via a movable pin 63 .

[0029] In this embodiment: an 80mm*80mm square tube 3 is welded on the trolley steel structure 1 at the vertical part of the zipper main body 2, the length of the square tube 3 is 1.1 meters, and the lock bracket assembly 4 of the zipper main body 2 is welded to the end part of the square tube 3. When the driver is doing wind protection, he only needs to translate the zipper main body 2 to drive the lock head 6 to translate until the limit block 62 at one end of the lock head 6 clamps the two side panels 41 and aligns the live pin sockets of the side panels 41 with the live pin sockets of the limit block 62, and then insert the live pin 63, and the wind protection can be done normally. When releasing, he only needs to remove the live pin 63 and translate the zipper main body 2 outward to release the wind protection. When doing wind protection and releasing wind protection, there is no need to lift up or carry down the heavier zipper main body 2. A driver can basically complete the wind protection or release of a zipper main body 2 within 2 minutes, which greatly saves manpower and improves efficiency. Compared with the original method, there is no need to stand on the motor guardrail to carry it, and the safety is also improved.

[0030] Example 2

[0031] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 2 A mounting hole 421 is opened on the side wall of the mounting horizontal plate 42 , and the proximity switch 5 penetrates and is fixedly connected inside the mounting hole 421 .

[0032] In this embodiment: the proximity switch 5 is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the proximity switch 5 to the action distance, the switch can be activated without mechanical contact or applying any pressure, thereby driving a DC appliance or providing control instructions to a computer (PLC) device. This is a prior art. When the zipper body 2 does not return to its position after the truck releases the windproof zipper anchor, a fault reminder will be reported, further improving safety.

[0033] Working principle: When doing wind protection, the zipper body 2 is translated to drive the lock head 6 to translate, and the limit block 62 at one end of the lock head 6 clamps the two side panels 41 therebetween. At this time, the movable pin sockets of the side panels 41 are aligned with the movable pin sockets of the limit block 62, and then the movable pin 63 is inserted to complete the fixation of the zipper body 2. When releasing, it is only necessary to remove the movable pin 63 and translate the zipper body 2 outward to release the fixation of the zipper body 2. At the same time, an installation hole 421 is opened on the installation horizontal plate 42 of the lock bracket assembly 4, and a proximity switch 5 is installed inside it. When the zipper body 2 is not put in place, a reminder is issued.
