[0028] A locking member 7 is arranged in the middle of the top edge of the bearing plate 2 for locking and releasing the towing rope 6;

[0029] A guiding member 8 is arranged in the middle of the bottom edge of the frame 1 for guiding the towing rope 6 to the middle of the top edge of the bearing plate 2.

[0030] Specific implementation process and principle description of this rail trolley:

[0031] During use, the staff place heavy objects or construction materials to be transported on the bearing plate 2 of the rail trolley. The worker pushes the trolley to make it travel along the set track to the designated position. During the pushing process, the traction rope 6 is kept in a locked state through the locking member 7, so that the braking mechanism 5 does not work and the wheels 4 can rotate normally. When it is necessary to stop the trolley, the worker operates the locking member 7 to release the traction rope 6, and the braking mechanism 5 is immediately activated. The spring 504 pushes the bolt 502 into the pin hole 401 on the surface of the wheel 4 to stop the rotation of the wheel 4, thereby preventing the trolley from slipping. When it is necessary to restart the trolley, the worker operates the locking member 7 again to lock the traction rope 6, so that the braking mechanism 5 does not work and the wheels 4 resume rotation.

[0032] As Figure 4 shown, in some embodiments, the mounting cylinder 501 is composed of a cylinder cover 5011 and a cylinder body 5012 fixedly arranged on one side of the C-shaped seat 3. The cylinder cover 5011 and the cylinder body 5012 are in threaded connection. More specifically, since the threaded connection provides a simple disassembly and assembly method, maintenance personnel can quickly check the inside of the mounting cylinder 501 and perform maintenance work such as cleaning, lubricating or replacing internal parts.

[0033] As Figure 2 shown, in some embodiments, the locking member 7 includes an L-shaped seat 701 fixedly arranged at intervals in the middle of the top edge of the bearing plate 2. A first arc-shaped notch 7011 is formed at the corner of the L-shaped seat 701, and a second arc-shaped notch 7012 is formed at one end of the L-shaped seat 701. One end of the traction rope 6 away from the bolt 502 is connected with a limiting rod 702. Both the first arc-shaped notch 7011 and the second arc-shaped notch 7012 are adapted to the size of the limiting rod 702. More specifically, when it is necessary to stop the trolley, the operator inserts the limiting rod 702 into the first arc-shaped notch 7011. At this time, the traction rope 6 is locked, and the spring 504 pushes the bolt 502 into the pin hole 401 on the surface of the wheel 4 to stop the rotation of the wheel 4; when it is necessary for the trolley to continue to travel, the operator moves the limiting rod 702 to the second arc-shaped notch 7012. At this time, the end of the bolt 502 disengages from the pin hole 401 on the surface of the wheel 4, and the wheels 4 can rotate normally. Through simple operations, the braking and release of the trolley can be realized, improving work efficiency.

[0034] As Figure 2 shown, in some embodiments, a push rod 703 is fixedly arranged at the bottom of the L-shaped seat 701, and a rubber sleeve is arranged at the end of the push rod 703. More specifically, the rubber sleeve provides a good grip, making the feel more comfortable when operating the push rod 703, reducing the fatigue of the operator. In addition, the rubber material has an anti-slip effect, which can increase the stability and safety during operation and reduce mistakes during the operation process.

[0035] like Figure 3 As shown, in some embodiments, the guide member 8 includes a fixed plate 801 in the middle of the bottom edge of the frame 1, a T-shaped plate 802 is fixedly provided on one side of the fixed plate 801, and first guide wheels 803 are rotatably connected on both sides of the T-shaped plate 802, and an L-shaped square tube 804 is fixedly provided on the other side of the fixed plate 801, and a second guide wheel 805 is rotatably provided at the end of the L-shaped square tube 804. More specifically, by setting the guide member 8 in the middle of the bottom edge of the frame 1, it is possible to ensure that the traction rope 6 maintains the correct direction and path during movement, avoid rope jumping or entanglement, and thus ensure a smooth response of the braking mechanism. When in use, the traction rope 6 is led out from the end of the pin 502, then enters the wheel groove of the first guide wheel 803, passes through the L-shaped square tube 804, and then enters the wheel groove of the second guide wheel 805, and finally connects with the limit rod 702.

[0036] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
