[0021] Reference Figure 2 and Figure 3 When the slide rail 5 is in an inclined state, the load on the slide rail 5 is large due to the mass of the counterweight 4, which easily causes damage to the worm wheel 63 and the worm 62. Therefore, in the embodiment of the present application, a lifting rope 8 is provided on the mounting frame 1, and a fixing rod is fixedly provided at the end of the lifting rope 8, and the fixing rod is fixedly provided on the side of the slide rail 5.

[0022] Reference Figure 2 and Figure 3 In the embodiment of the present application, two slide rails 5 are provided and are parallel to each other. Slide grooves 10 are provided on the surfaces facing each other of the slide rails 5. The counterweight block 4 is slidably engaged in the slide grooves 10. A driving rod 11 is provided across the two slide rails 5. The driving rod 11 is perpendicular to the length direction of the slide rails 5. Both ends of the driving rod 11 are slidably engaged in the slide grooves 10. The driving rod 11 is located on the side of the counterweight block 4 away from the winch 2 and abuts against the counterweight block 4.

[0023] Reference Figure 3 In the embodiment of the present application, in order to increase the weight of the counterweight block 4 and reduce the number of counterweight blocks 4 put in, the counterweight block 4 is hollow, and a counterweight box is provided on the mounting frame 1, and a counterweight liquid and a delivery pump are provided in the counterweight box. In the embodiment of the present application, the counterweight liquid is a metal liquid, for example, mercury liquid, etc., and a delivery pipe is provided on the delivery pump, which is connected to the counterweight block 4; when the overall mass of the counterweight block 4 is increased, the delivery pump is started, and the delivery pump drives the counterweight liquid into the counterweight block 4, thereby increasing the mass of the counterweight block 4 and reducing the number of counterweight blocks 4 put in.

[0024] Reference Figure 3 and Figure 4In the embodiment of the present application, in order to increase the number of counterweight blocks 4 and adapt to the weight of the actuator, a placement frame 15 is provided on the mounting frame 1, and the counterweight block 4 is located on the placement frame 15. The counterweight block 4 is laid flat on the placement frame 15, and a first notch 16 is opened on the placement frame 15. Furthermore, a second notch 17 is opened on the mounting frame 1, and an entry notch 18 is opened on the top of the slide rail 5. The first notch 16, the second notch 17 and the entry notch 18 are connected to each other. A moving part is provided on the placement frame 15, and the moving part is used for the counterweight block 4 to enter the slide rail 5 through the entry notch 18. The moving part includes a first electric push rod 19 arranged on the placement frame 15 and an electromagnet 20 arranged on the output shaft of the first electric push rod 19. A metal plate adsorbed by the electromagnet 20 is fixed on the surface of the counterweight block 4 facing the electromagnet 20. The first electric push rod 19 adsorbs the counterweight block 4 and pulls the counterweight block 4 to slide to the top of the entry notch 18 and fall into the slide rail 5. When the number of counterweight blocks 4 on the slide rail 5 is increased, the first electric push rod 19 is started, and the first electric push rod 19 drives the electromagnet 20 to be adsorbed on the counterweight blocks 4 to push all the counterweight blocks 4 to slide. Then the counterweight blocks 4 pass through the first gap 16, the second gap 17 and the entrance gap 18, and enter the slide rail 5, and then slide along the slide rail 5. The operation is simple and convenient.

[0025] Reference Figure 4 and Figure 5 Furthermore, due to the large mass of the counterweight 4, when the counterweight 4 falls into the slide rail 5, the impact force on the slide rail 5 is relatively large. In order to reduce the impact force of the counterweight 4 on the slide rail 5, a receiving plate 21 is provided in the slide rail 5 and directly below the entrance notch 18, and a buffer pad is laid on the receiving plate 21; under the action of the buffer pad, the fall of the counterweight 4 is buffered, thereby reducing the impact on the slide rail 5.

[0026] Reference Figure 4 and Figure 5 In the embodiment of the present application, in order to reduce the number of counterweights 4 on the slide rail 5 and adapt to the mass of the actuator, the receiving plate 21 is slidably arranged in the slide rail 5, and the receiving plate 21 slides along the depth direction of the slide groove 10. The slide rail 5 is provided with a second electric push rod 22 for driving the receiving plate 21 to slide; under the action of the walking motor 12, the counterweight 4 is pushed to move onto the receiving plate 21, and then the receiving plate 21 is pushed to slide by the second electric push rod 22, and the receiving plate 21 drives the counterweight 4 to pass through the entry gap 18, the second gap 17 and the first gap 16, and then the counterweight 4 is driven to move back to the placement rack 15 through the first electric push rod 19.

[0027] When the walking motor 12 pushes the counterweight 4 to move onto the receiving plate 21, in order to facilitate the counterweight 4 to be placed directly below the entry gap 18, a limit block is slidably arranged on the receiving surface of the receiving plate 21. When the limit block is used to abut against the limit block, the counterweight 4 located on the receiving plate 21 is directly below the entry gap 18; the walking mechanism pushes the counterweight 4 to move and only abuts against the limit block, thereby positioning the counterweight 4.

[0028] Reference Figure 4 In order to facilitate the additional counterweight block 4 to become an integral whole with the counterweight block 4 in the slide rail 5, a hook 23 is provided on one side of the counterweight block 4, and a hanging ring 24 for the hook 23 to be hung is provided on the other side. The hook 23 is L-shaped and faces downward; the falling counterweight block 4 is hung on the hanging ring 24 through the hook 23. At this time, the additional counterweight block 4 is placed on the counterweight block 4 in the middle of the slide rail 5.

[0029] The implementation principle of a weight balancing system in the embodiment of the present application is: When hoisting heavy objects, a proper counterweight 4 is added to the slide rail 5 so that the mass of the counterweight 4 matches the mass of the actuator. At this time, the winch 2 is started, the winch 2 drives the wire rope 3 to move, the wire rope 3 hangs on one side of the actuator and rises, and the counterweight 4 falls. In this process, the counterweight 4 applies partial tension to the actuator, thereby reducing the power of the winch 2, thereby reducing the consumption of electric energy; When the weight balancing system is used in an elevator, the slide rail 5 is in a vertical state and the elevator is raised and lowered; when the weight balancing system is used in a lifting equipment such as a crane, the mounting frame 1 is mounted on the lifting arm of the crane, and then the slide rail 5 is driven to rotate by the first driving member 6, and the slide rail 5 is in an inclined state. The counterweight 4 slides along the slide rail 5 and drives the actuator to move upward. When the actuator is a tamping hammer, the tamping hammer needs to fall in a manner similar to a free fall. At this time, the counterweight 4 slides toward the winch 2, and the wire rope 3 between the counterweight 4 and the winch 2 is in a relaxed state. Then the winch 2 cancels the self-locking restriction, and then the tamping hammer falls and acts on the ground. When the tamping hammer rises, the first driving member 6 drives the slide rail 5 to rotate, and the slide rail 5 is in a vertical or inclined state, so that the counterweight 4 drives the tamping hammer to rise, thereby reducing the consumption of electric energy.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
