DETAILED DESCRIPTION
[0016] The following will be combined with the drawings of the specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] Combination Figure 1-Figure 2 As shown, the utility model provides a technical solution: an anti-dumping device for a two-layer translational stereo garage carrier, the anti-dumping device is installed at the bottom of the carrier column, and the anti-dumping device is used to penetrate into the groove of the H-shaped steel track, including a mounting frame 15, a shaft 2 is provided in the middle of the mounting frame 15, and a top shaft 5 is provided on the top of the shaft 2, which plays a core supporting role of the entire device. The two sides of the top shaft 5 are cleverly connected to the second roller 4 through the shaft elastic retaining ring 6. The shaft elastic retaining ring 6 is made of high-strength material, which can effectively prevent the second roller 4 from falling off or shifting during the working process. This design enables the second roller 4 to rotate flexibly on the top shaft 5 while maintaining sufficient stability;
[0018] Furthermore, a top-layer bushing 14 is provided on the inner and outer sides of the second roller 4. This design not only enhances the wear resistance between the roller and the shaft, but also improves the service life of the entire device. The use of the top-layer bushing 14 effectively reduces friction and wear, so that the device can still maintain good performance after long-term use. The top-layer bushing 14 is made of a wear-resistant material with good lubrication performance, which can reduce the friction between the roller and the contact surface and improve the service life of the device.
[0019] The shaft 2 is rotatably connected to the first roller 1 through a deep groove ball bearing 3. This connection mode enables the first roller 1 to rotate smoothly on the shaft 2, while also ensuring the stability and accuracy of the rotation.
[0020] It is worth mentioning that the first roller 1 and the second roller 4 are matched with the H-shaped steel web and the lower part of the wing plate respectively, and a certain gap is maintained between the two and the H-shaped steel web and the lower part of the wing plate to achieve smooth rolling and stable support. This design enables the device to fit the shape of the H-shaped steel groove closely, achieving high-precision positioning and support. The clearance fit design ensures that the roller will not be subject to excessive resistance during the rotation process, thereby improving the working efficiency of the entire device;
[0021] In addition, a gasket 10 is fixedly installed on one side of the mounting frame 15 by a first hexagon socket head screw 9 and a first flat washer 11. This fixing method is both firm and reliable, and can effectively prevent the gasket 10 from loosening or falling off during use. The presence of the gasket 10 further enhances the stability and sealing between the device and the H-shaped steel groove;
[0022] Finally, the shaft 2 is fixed on the mounting frame 15 by a second hexagon socket head screw 12 and a second flat washer 13. This fixing method also has high stability and reliability, ensuring that the position of the shaft 2 on the mounting frame 15 will not shift or shake.
[0023] In the embodiment of the present invention, during the operation of the carrier, due to various reasons, abnormal vibration and left-right sliding may occur. In order to deal with this situation, an efficient anti-dumping device is designed. The device limits the upper and lower and left and right positions of the bearings through the track grooves, effectively ensuring the stable operation of the carrier in abnormal conditions.
[0024] Specifically, when the carrier vibrates up and down due to some faults, the second roller of the anti-dumping device will contact the upper part of the H-shaped steel groove of the track. This design ensures that the amplitude of the up and down vibration of the carrier is strictly limited to the gap between the second roller and the track. In this way, even if the carrier fails, the amplitude of its up and down vibration can be guaranteed to be within a controllable range, thereby avoiding the occurrence of dangerous situations such as wheel derailment or dumping due to excessive vibration of the carrier.
[0025] In addition, when the wheels of the carrier slip left and right for some reason, the first roller of the anti-dumping device will contact the side of the H-shaped steel groove of the track. This design limits the left and right sliding distance of the carrier to the gap between the lower bearing and the side of the track. The existence of this mechanism ensures that the sliding distance is within a controllable range when the wheels of the carrier slip due to a malfunction, thereby avoiding the risk of wheel derailment or dumping due to excessive slippage of the carrier.
[0026] In summary, this anti-dumping device is cleverly designed and powerfully functional. It limits the bearing up and down and left and right through the track grooves to ensure the stable operation of the transporter under abnormal conditions. At the same time, it also greatly reduces the risk of accidents such as wheel derailment or dumping during the operation of the transporter, thereby improving the safety and stability of the entire transport process. The application of this device undoubtedly provides a strong guarantee for the stable operation of the transporter.
[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
