[0036] The guide wheel 303 group generally contacts the guide rail in the form of a vertical angle, and there is no adjustment gap or the adjustment is achieved by using long holes. This structure can adjust the gap of the guide wheel 303 in time, but it cannot improve the fit between the guide wheel 303 and the guide rail surface. During installation, high installation accuracy is required. The guide wheel 303 needs to fit exactly with the guide rail surface to slide smoothly. Therefore, there are problems of inconvenience in installation and easy jamming of the rail. In the present utility model, the guide wheel assembly 300 adopts a guiding form with an oblique angle and an inclined guide rail surface, so that the gap between the guide wheel 303 and the guide rail surface can be adjusted by adjusting the position of the guide wheel 303, thereby ensuring the guidance of the counterweight and making installation and adjustment more convenient.

[0037] Reference Figures 1 to 8 , a new counterweight system of the utility model is implemented as follows:

[0038] A novel counterweight system includes a counterweight assembly, a counterweight block 400, a sling 100, two guide rail assemblies 600, and a plurality of guide wheel assemblies 300. The sling 100 is connected to a lifting medium such as a chain, a wire rope, or a lifting belt to achieve the hanging of the counterweight. The counterweight block 400 is loaded into the counterweight frame 200 according to the actual weight requirement, and the counterweight block 400 is locked in the counterweight frame 200 by an anti-slip device 500, ensuring that the counterweight block 400 does not fall out of the counterweight frame 200 during the lifting process or in the state of vibration or falling, thereby avoiding safety accidents caused by the falling of the counterweight block 400. The guide wheel assembly 300 and the guide rail assembly 600 are in oblique contact, which not only meets the guidance requirements but also avoids the problem of the gauge being snapped due to vertical compression. This method is more convenient and less likely to get stuck.

[0039] See also Figure 4 The sling 100 includes a lifting block 101, a hanging plate welded part 102, a pin 103, a hanging point screw 104, a hanging nut 105, a set screw 106, and a fixing plate 107. The lifting block 101 is connected to the lifting medium to achieve the suspension of the counterweight system; the lifting block 101 is connected to the hanging plate welded part 102 via the screw 104, and the distance between the lifting block 101 and the hanging plate welded part 102 is adjusted and fixed by the hanging nut 105; the lower end of the hanging plate welded part 102 is installed and fixed to the connecting seat 204 in the counterweight frame 200 via the pin 103, thereby achieving the connection between the sling 100 and the counterweight frame 200; the pin 103 is fastened to the hanging plate welded part 102 via the set screw 106 and the fixing plate 107 to prevent the pin 103 from moving in the axial direction.

[0040] See also Figure 5 The counterweight frame 200 includes a frame longitudinal beam 201, a frame cross beam 202, a sealing plate 203, and a connecting seat 204. The frame longitudinal beam 201 and the frame cross beam 202 are welded to form a U-shaped counterweight frame 200 body. The two sides are sealed by welding sealing plates 203. At the same time, connecting seats 204 are welded to the left and right frame longitudinal beams 201 to form a counterweight frame 200 with a mounting port on the upper side, ensuring the stability and rigidity requirements of the entire frame. When installing the counterweight block 400, the counterweight block 400 is installed into the counterweight frame 200 through the mounting port. Compared with the traditional horizontal installation of the counterweight block 400, it is more convenient to install the counterweight block 400 into the counterweight frame 200 or remove the counterweight frame 200.

[0041] See also Figure 6An anti-slip device 500 is provided between the counterweight frame 200 and the counterweight block 400 to lock the counterweight block 400 in the counterweight frame 200. The anti-slip device 500 includes a plurality of anti-slip parts, which can be screws, nuts or pins. Two lifting holes 401 are provided above the counterweight block 400 to facilitate the handling of the counterweight block 400 during lifting or installation. At the same time, after the counterweight block 400 is installed in the counterweight frame 200, the lifting holes 401 can be connected and fixed by the screws and nuts in the anti-slip device 500, thereby locking the counterweight block 400 in the counterweight frame 200 and preventing it from falling out of the counterweight frame 200. In some other embodiments, the anti-slip device 500 can be a first slot provided on the counterweight frame 200 and a second slot provided on the counterweight block 400, the second slot and the second slot being engaged, and then being threadedly connected to the counterweight frame 200 and the counterweight block 400 respectively with reinforcing screws. In some other embodiments, the anti-slip device 500 can be a first magnetic component provided on the counterweight frame 200 and a second magnetic component provided on the counterweight block 400. The first magnetic component and the second magnetic component attract each other to fix the counterweight block 400.

[0042] See also Figure 7 The number of guide wheel assemblies 300 is four. In other embodiments, the number of guide wheel assemblies 300 can be six according to actual conditions. The four guide wheel assemblies 300 are respectively provided on the left and right sides of the counterweight frame 200 to guide the two sides of the counterweight frame 200. The guide wheel assembly 300 includes a connecting plate 301, a guide wheel support 302, a guide wheel 303, a wheel shaft 304, a first connecting bolt 305, an adjusting connecting nut 306, a washer 307, and a first locking nut 308. The connecting plate 301 is provided with a mounting hole, which is provided with an adjusting nut 306 for rotation. The first connecting bolt 305 is provided in the mounting hole so as to slide left and right. The first connecting bolt 305 is threadedly connected to the adjusting nut 306. By rotating the adjusting nut 306, the first connecting bolt 305 slides left and right. After adjusting to the appropriate position, the adjusting nut 306 can be tightened with the first locking nut 308 to abut the side of the connecting plate 301, providing further stability. The first connecting bolt 305 is provided with a washer 307, which is provided between the adjusting nut 306 and the connecting plate 301. The washer 307 prevents loosening, disperses pressure, and protects the bolt and nut. The connecting plate 301 is fixed to the counterweight frame 200 at four ends, each at the top and bottom, by bolts or welding. It is connected to the guide wheel support 302 by the first connecting bolts 305. The gap between the guide wheel support 302 and the guide rail assembly 600 can be adjusted by adjusting the connecting nut 306 on the first connecting bolt 305.

[0043] A bending plate 309 is provided on the guide wheel support 302, which is installed at a 45° angle to the bevel. The two guide wheels 303 are installed on the bending plate 309 via the wheel axle 304, the adjusting connecting nut 306, and the washer 307. After installation, the guide wheel assembly 300 is installed at a 45° angle to the guide rail assembly 600, thereby achieving the adjustability of the gap between the guide wheel assembly 300 and the guide rail assembly 600, while avoiding the problem of easy caliper when installed at a vertical angle. In other embodiments, the bevel angle of the bending plate 309 can be other angles, such as 30 degrees. Correspondingly, the angle between the two guide rail surfaces arranged at an angle is also adjusted to 30 degrees. The two guide wheels 303 are respectively arranged on the front and rear sides of the counterweight guide rail 601, that is, arranged on the same horizontal plane. The two guide wheels 303 are respectively arranged on the front and rear sides of the counterweight guide rail 601 to ensure that the counterweight device remains stable during movement. This arrangement helps prevent the counterweight device from shaking or deflecting during movement, thereby improving overall stability. And being able to share the weight of the counterweight device and the friction during movement helps reduce the wear of the counterweight guide rail 601 and extend the service life of the counterweight guide rail 601. In some other embodiments, the two guide wheels 303 can also be set up in an up-down staggered manner. In some special cases, such as when space is limited or a special arrangement of the counterweight device is required, the two guide wheels 303 can be set up in an up-down staggered manner. This arrangement can save space while ensuring the stability and safety of the counterweight device.

[0044] See also Figure 6 There are two sets of guide rail assemblies 600, one on each side of the counterweight frame 200, corresponding to the guide wheel assembly 300. The guide rail assembly 600 includes a counterweight guide rail 601, a guide rail connecting plate 602, a guide rail mounting bracket 603, a second connecting bolt 604, a guide rail nut 605, and a second locking nut 606. The counterweight guide rail 601 is connected to the guide rail connecting plate 602 and the guide rail mounting bracket 603 via the second connecting bolt 604 and the guide rail nut 605, thereby securing the counterweight guide rail 601. The cross-section of the counterweight guide rail 601 is V-shaped, corresponding to the 45° angle formed by the guide wheel 303 in the guide wheel assembly 300, ensuring guiding contact between the guide wheel assembly 300 and the guide rail assembly 600.

[0045] The cross-section of the counterweight guide rail 601 is V-shaped, making its structure more stable and simpler. In other embodiments, the counterweight guide rail 601 can be composed of two vertically extending guide rails, each of which has a V-shaped cross-section. The two guide rails are fixed by other structures, that is, the counterweight guide rail 601 does not need to be provided as an integral whole.

[0046] During use, the sling 100 drives the counterweight frame 200 up and down on the counterweight guide rail 601, improving the stability of the counterweight assembly. During installation, the distance between the guide wheel 303 and the guide rail surface can be adjusted to allow the guide wheel 303 to slide more smoothly on the guide rail surface, making installation more convenient and less likely to get stuck on the rail, while reducing the structural precision requirements of the entire device. Furthermore, the use of a vertical counterweight block 400 and the provision of a lifting hole 401 that also serves as an anti-slip fixing hole on the counterweight block 400 ensure the convenience of installation and lifting of the counterweight block 400 while preventing the counterweight block 400 from loosening during the lifting process.

[0047] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
