[0024] Example 1

[0025] See also Figure 1 and Figure 2The utility model provides a latch-type self-locking tool trolley, which includes a trolley body 1, a first rotating shaft 2 and a second rotating shaft 3, a material I-shaped wheel 5 and a cloth I-shaped wheel 6, a first driving disc 71 and a second driving disc 72, a first brake disc 81 and a second brake disc 82, a first locking member and a second locking member; the trolley body includes a frame 11; the first rotating shaft 2 and the second rotating shaft 3 are respectively mounted on the left and right ends of the frame 11; the material I-shaped wheel 5 and the cloth I-shaped wheel 6 are respectively mounted on the first rotating shaft 2 and the second rotating shaft 3; the first driving disc 71 and the second driving disc 72 are respectively mounted on one end of the first rotating shaft 2 and the second rotating shaft 3; the first brake disc 81 and the second brake disc 82 are respectively mounted on the first rotating shaft 2 and the second rotating shaft 3, the first brake disc 81 is located on the inner side of the first driving disc 71, and the second brake disc 82 is located on the inner side of the second driving disc 72. In this way, the first driving disc 71 and the second driving disc 72 are arranged on the outside to facilitate the docking of the driving chuck.

[0026] The first brake disc 81 and the second brake disc 82 include a wheel body, and the wheel body forms a plurality of limit slots 80 at intervals along the circumference thereof. It can be understood that the first brake disc 81 and the second brake disc 82 are fixed as a whole with the first rotating shaft 2 and the second rotating shaft 3, and then rotate accordingly. Since the limit slots are arranged at intervals along the circumference, when the first brake disc 81 and the second brake disc 82 rotate to a predetermined position, the limit slots corresponding to the limit pins can be used as locking positions for locking. This design can effectively control the position of the brake disc, so that it stays and locks at a specific position, thereby ensuring the stability and reliability of the system when it is working or stopped. The arrangement of the limit slots provides a simple and effective locking mechanism, which enables the brake disc to stay accurately at the desired position, meeting the requirements of system design.

[0027] The first locking member 9 and the second locking member 10 are installed on the vehicle frame, and are respectively adapted to the first brake disc 81 and the second brake disc 82 to lock or unlock the first brake disc 81 and the second brake disc 82. The first locking member 10 and the second locking member 9 cannot hinder the docking of the drive disc, and the unlocking and locking processes thereof should be as far away as possible from the first drive disc 71 and the second drive disc 72. The first locking member 9 and the second locking member 10 provided in this embodiment have the same structure, and only the structure of the second locking member 9 is described below: the second locking member includes a brake support 91 connected to the vehicle frame, a swing arm 92 swingably connected to the brake support 91, a limit pin 93 arranged at the free end of the swing arm 92, and an elastic reset member 94 connected between the brake support 91 and the swing arm 92, the limit pin 93 has a locking state of limiting with the limit slot 80 and an unlocking state of escaping from the limit slot 80, and the elastic reset member 94 makes the limit pin always in the locking state.

[0028] For example, the elastic reset member 94 is a compression spring. The swing arm 92 is rotatably mounted on the brake support 91 via a hinge 95 .

[0029] The present embodiment provides a latch-type automatic unlocking trolley; the first brake disc 81 and the second brake disc 82 and the first rotating shaft 2 and the second rotating shaft 3 are fixed as an integral structure; the head of the brake swing arm 92 is provided with a brake limit pin 93, one end of the brake swing arm 92 is mounted on the brake support 91 through a hinge 95, etc., and a compression spring 94 is installed on the rear side of the other end; when there is no external force, the force of the compression spring 94 pushes the brake swing arm 92 outward, and the brake limit pin 93 is inserted into the brake disc's card slot 80, and the I-shaped wheels 5, 6 are fixed in the circumferential direction and cannot rotate, that is, the locked state; when there is an external force to push the brake swing arm 92 toward the vehicle body 11, the brake swing arm 92 overcomes the elastic force of the compression spring and moves toward the vehicle body together, the brake limit pin 93 and the limit slot 80 on the brake disc are disengaged, the I-shaped wheels 5, 6 are not subjected to force in the circumferential direction, and can be driven by the driving device to freely rotate and unlock the state.

[0030] The automatic unlocking device ensures that the trolley can move freely when needed (unlocked state) and stops firmly after the operation is completed (locked state), which helps to improve the safety of the working process. The automatic unlocking and locking process is controlled by the device without manual intervention, which simplifies the operation process and improves the convenience and efficiency of operation.

[0031] When the self-locking trolley provided by the utility model is applied to a workstation, the unlocking device and the driving device are extended at the same time, which can ensure that they complete the action at the same time point, improve the synchronization of the operation, avoid the problems caused by asynchronous action, simplify the operation steps, reduce the burden on the operator, and improve the convenience and comfort of the operation.

[0032] In some preferred embodiments of the utility model, the rear side of the swing arm is provided with a first positioning rod 96 and a second positioning rod 97, wherein the first positioning rod 96 is located above the swing arm 92, and the second positioning rod 97 is located below the rotation position (i.e., hinge position) of the swing arm 92. When the stop pin 93 is in a locked state, the first positioning rod 96 is away from the brake support 91, and the second positioning rod 97 is against the brake support 91. In this way, the second positioning rod 97 and the stop pin are respectively located at the two ends of the swing arm 92 and arranged in opposite directions. At this time, the second positioning rod 97 is against the brake support 91, which can provide additional support and stability, so that the swing arm has better rigidity during operation, reduces vibration and deformation, and improves the stability of the system. The second positioning rod 97 is against the brake support 91, which can limit the swing range of the swing arm, ensure that the swing arm moves within the specified range, thereby reducing unnecessary swinging and ensuring the accuracy of operation. The arrangement of the second positioning rod 97 can make the swing arm have a more accurate positioning, which is conducive to ensuring that the swing arm stays at the required position and improving the working accuracy and stability. When the limit pin is in the unlocked state, the second positioning rod 97 is away from the brake support 91, and the first positioning rod 96 is against the brake support 91. In this way, the first positioning rod 96 limits the swing range of the swing arm 92 toward the vehicle body, avoiding the swing arm 92 from hitting the vehicle body, protecting the vehicle body and the swing arm from damage, and extending the life of the brake assembly.

[0033] The brake support includes a mounting plate, and a compression spring member 94 is connected between the mounting plate and the rear side of the swing arm 92 .

[0034] In this embodiment, the first drive disc and the second drive disc, the first brake disc and the second brake disc are installed at both ends of the first rotating shaft and the second rotating shaft; and the first locking member and the second locking member are installed at the left end or the right end of the first rotating shaft and the second rotating shaft. By installing the drive disc and the brake disc at both ends, the double-end balanced transmission of the swing arm or the transmission system can be achieved, ensuring the balance of force and torque, reducing vibration and instability, and improving the reliability of the system. By installing the drive disc at both ends, a double-end driving force can be provided, the output of the transmission force can be increased, and it is helpful to improve work efficiency and performance. Installing the drive disc and the brake disc at both ends can realize two-way operation, so that the system can run forward and reverse, increasing the flexibility and applicability of operation. Installing the same drive disc and brake disc at both ends can be used as spare parts. When one side fails or needs to be replaced, the drive disc and brake disc on the other side can be directly activated to reduce the downtime of the system.

[0035] The left and right sides of the first rotating shaft and the second rotating shaft are installed on the left and right sides of the frame through bearings.

[0036] The trolley also has a plurality of traction rollers 20 for traction of the peeled material.
