[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified. Example

[0031] like Figure 1As shown, the utility model provides an unlocking system for a trolley brake device, including a trolley guide-opening station, a limit assembly for limiting the trolley 1 is arranged on the trolley guide-opening station, a lifting unit 302 is arranged on the limit assembly at a position corresponding to the brake lever 103, the lifting unit 302 includes a connecting piece arranged at the end of the brake lever 103, so that the connecting piece drives one end of the brake lever 103 to perform lifting movement during the lifting movement, a sensing component for sensing the trolley 1 is arranged on the limit assembly, the sensing component and the lifting unit 302 are respectively connected to a central controller, and the central controller controls the lifting movement of the connecting piece according to the detection signal of the sensing component.

[0032] During use of the utility model, the staff moves the trolley 1 to the trolley guide position, and when the trolley 1 moves to the position of the limit assembly, the brake lever 103 of the trolley 1 is placed toward the lifting unit 302, so that the lifting unit 302 can control the brake device of the trolley 1;

[0033] The limit assembly is provided with a sensing assembly for sensing the trolley 1. The sensing assembly monitors the placement status of the trolley 1 on the trolley guide station and transmits the monitoring signal to the central processing unit. The lifting and lowering movement of the lifting unit 302 is controlled by a set program in the central processing unit, thereby realizing automatic control of the braking device, reducing the operating procedures of the staff, and avoiding operating errors and other problems during manual control.

[0034] Furthermore, in order to realize the automated operation of the unwinding process on the trolley 1, the driving unit 6 is also connected to the central controller, so that the central controller can control the braking device of the trolley 1 through the lifting unit 302 while synchronously controlling the driving units 6 of the large and small I-shaped wheels 102, thereby realizing the automated operation of the trolley unwinding process.

[0035] Specifically, Figure 1 , Figure 3As shown, the limit assembly includes a first limit baffle 201 and a second limit baffle 202, the spacing distance between the first limit baffle 201 and the second limit baffle 202 matches the structure of the trolley 1, and the first limit baffle 201 is provided with the lifting unit 302. When the trolley 1 is located between the limit assemblies and the large I-shaped wheel 101 and the small I-shaped wheel 102 are respectively connected to the first drive unit 6 and the second drive unit 6, the end of the brake lever 103 is located toward the first limit baffle 201, and the connecting member is a first baffle 301 arranged at the lower end of the brake lever 103. When the first baffle 301 rises to the highest position, the first baffle 301 maintains a supporting state for the brake lever 103.

[0036] The sensing component includes a proximity switch 402 arranged on one side of the second limit baffle 202 and a second baffle 401 arranged on the second limit baffle 202, and the second baffle 401 can be flipped on the second limit baffle 202. When the trolley 1 moves to the position of the limit component, the staff confirms the connection status between the large I-shaped wheel 101 and the small I-shaped wheel 102 and the first drive motor and the second drive motor respectively, and then flips the second baffle 401 so that the proximity switch 402 cannot sense the position of the second baffle 401. The central controller drives the connecting part of the lifting unit 302 to move upward according to the signal sent by the proximity switch 402. As the brake lever 103 rises, the brake device releases the brake state of the large I-shaped wheel 101 and the small I-shaped wheel 102, and then drives the drive unit 6 to perform the guide-off process.

[0037] Furthermore, the second baffle 401 and the proximity switch 402 are arranged at one end of the second limit baffle 202, so that the second baffle 401 forms a limiting structure for one end of the trolley 1 when it is in the flipped state, thereby further improving the stability of the trolley 1 in the guide-off process and avoiding displacement of the trolley 1, which causes the large I-shaped wheel 101 and the small I-shaped wheel 102 on the trolley 1 to separate from the drive unit 6 respectively.

[0038] In order to achieve the smooth progress of the trolley guide process, it is necessary to ensure the connection stability between the large I-shaped wheel 101 and the small I-shaped wheel 102 and the first driving click and the second driving click respectively, and the large I-shaped wheel 101 and the small I-shaped wheel 102 and each driving unit 6 are connected through the plug-in assembly;

[0039] like Figure 2As shown, the plug-in assembly includes a card connector and a plug-in connector, the card connector includes a flange 501 arranged at the end positions of the large I-shaped wheel 101 and the small I-shaped wheel 102, the flange 501 is provided with a plurality of slots for installing the plug-in connector, the plug-in connector includes a latch 502 that matches the slots of the flange 501, the latch 502 is arranged on one side of the disc, the disc is arranged at the end of the bearing 601 of the drive unit 6, the disc rotates with the bearing 601, the bearing 601 is provided with the limit block 503, and the damping spring 504 is arranged between the limit block 503 and the disc;

[0040] When the trolley 1 moves to the position of the limit assembly, the staff can align the connector with the slot of the connector and then push the trolley 1 horizontally. At this time, the disc with the connector is displaced along the direction of the bearing 601. The shock-absorbing spring 504 provided between the limit block 503 and the disc can effectively prevent the staff from making accidents during the process of moving the trolley 1, resulting in strong collisions at the connection positions between the large I-shaped wheel 101, the small I-shaped wheel 102 and each drive unit 6, thereby ensuring the possibility of damage between the trolley 1 and each drive unit 6 due to unexpected situations.

[0041] Furthermore, the second baffle plate 401 is arranged on the side away from the driving unit 6, and the clamping effect on both sides of the trolley 1 is achieved through the restoring elastic force of the shock-absorbing spring 504 and the limiting structure of the second baffle plate 401 on the trolley 1, thereby ensuring the structural stability of the trolley 1 during the guide-out process.

[0043] However, the above is only a specific embodiment of the present invention, and it cannot be used to limit the scope of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the protection scope of the present invention should still fall within the scope of the claims of the present invention.
