Description

Technical Field

[0001] This utility model relates to the field of detachable grips, and more particularly to a device for safety protection of detachable grips and a novel wheel. Background Technology

[0002] A cable grab, as the name suggests, is a mechanical structure that allows the grab to effectively detach from and reliably engage with the carrier cable (i.e., the steel wire rope). This design allows the cable car system's operating speed and the speed at which passengers board and alight to be independent of each other, without needing to maintain strict synchronization. Therefore, passengers can board and alight more safely and smoothly without affecting the normal operating speed of the cableway, thus achieving greater transport capacity and higher operational efficiency.

[0003] The hook and cable grip's ability to engage and disengage relies primarily on its key components: the running wheels, the loading wheels, and the balance wheels. These components work together to ensure the hook and cable grip can reliably perform opening and closing actions even at high speeds. The running wheels guide the movement along the track, the loading wheels bear the main load, and the balance wheels provide stability, preventing the hook and cable grip from swaying or shifting during dynamic operation.

[0004] However, most current detachable grips use nylon wheels with steel inserts as the balance wheel structure. Over time, the nylon material gradually loses its original properties due to natural aging, UV exposure, and temperature fluctuations. Furthermore, detachable grips typically operate at high speeds, experiencing frequent mechanical vibrations and impacts, further accelerating the fatigue process of the nylon wheel. Once the nylon portion of the balance wheel breaks or completely detaches, the grip will lose its necessary stability and balance, failing to properly open and close.

[0005] This situation can easily lead to malfunctions in the coordination between the cable gripper and the transport cable, which may not only cause severe wear or even cut the wire rope, but also cause major safety accidents such as vehicle derailment, system emergency stop, or collision between vehicles, posing a serious threat to passengers and equipment.

[0006] Therefore, it is necessary to develop a mechanism to prevent the nylon wheel of the balance wheel from breaking or falling off. Utility Model Content

[0007] The purpose of this utility model is to provide a device and a new type of wheel that provide better safety protection for detachment grips. The specific purpose is explained in the details of the implementation section.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A new type of wheel for safety protection of detachment grapples, characterized in that, The wheel is a balance wheel 3, which is rotatably mounted on a shaft. A spare wheel 8 is arranged coaxially on the side of the balance wheel. The diameter of the spare wheel 8 is smaller than that of the balance wheel 3. The balance wheel 3 is a nylon wheel, and the spare wheel 8 only works when the balance wheel 3 breaks.

[0009] A further technical solution of this utility model is that the spare wheel 8 is made of metal.

[0010] A further technical solution of this utility model is that the spare wheel 8 is directly fixed on the rotating shaft on which the balance wheel 3 is installed, or the spare wheel 8 is mounted on the rotating shaft on which the balance wheel 3 is installed using a bearing.

[0011] A further technical solution of this utility model is that the combined width of the spare wheel 8 and the balance wheel 3 is less than the width of the channel 11, that is, during operation, both the spare wheel 8 and the balance wheel 3 are located within the range of the channel 11.

[0012] A device for safety protection of a detachable grip, characterized in that it utilizes a novel wheel as described in any one of the above-mentioned safety protection methods for detachable grips. The balance wheel 3 is mounted on the rotating shaft via a bearing 7. The bearing 7 has a spacer ring 5, a spacer sleeve 6, and a cover 9 on its side. The spare wheel 8 and the balance wheel 3 are both located within the channel 11, thus achieving walking and positioning; During the advance operation, the loading wheel 1 will guide the clamping part 10 to gradually disengage or clamp.

[0013] A further technical solution of this utility model is that the clamping part 10 is located behind the shaft where the arm, spring, and balance wheel 3 are mounted on the loading wheel 1, forming a structure in which the clamping part 10 can be opened and closed due to the deformation of the spring.

[0014] The present invention, employing the above technical solution, offers the following advantages over existing technologies: To address the potential problem of nylon wheel breakage or detachment during the operation of the balance wheel, a spare wheel is specifically added to the front end of the balance wheel. This spare wheel is slightly smaller than the balance wheel and is made of highly durable materials to ensure a rapid and smooth takeover of the workload in the event of a balance wheel failure. When the nylon wheel of the balance wheel breaks or detaches due to wear, impact, or other reasons, the spare wheel immediately intervenes to maintain the normal opening and closing function of the gripper, thereby ensuring the continuous operation of the entire system. This design not only avoids operational interruptions caused by the gripper's inability to open and close properly due to balance wheel failure but also completely eliminates potential safety risks such as excessive wear, breakage, or even equipment collision accidents, greatly enhancing the reliability and safety of the device.
