Description
Technical Field
[0001] This utility model relates to the technical field of track anti-runaway vehicles, and in particular to a track anti-runaway vehicle device. Background Technology
[0002] Track refers to a route made of strips of steel for trains, trams, and other vehicles to run on. With the increase in railway freight volume and the improvement in locomotive and rolling stock axle loads and speeds, many new types of tracks have emerged, such as seamless tracks, wide-sleeper tracks, integral track beds, and slab tracks. Welded long rail tracks are a type of track where ordinary steel rails are welded together without gaps. Each welded rail is at least 200 meters long, but in practice, they are generally 800-1000 meters or longer. Long rails are laid and fixed to sleepers within a specified temperature range. The ends of long rails have gaps, while the middle section cannot expand or contract with temperature changes. Therefore, the middle section of the rail will experience significant temperature pressure in summer and significant temperature tension in winter. In subway and tunnel construction, the shield tunneling method is widely used due to its high safety, reliability, strong adaptability to the surrounding environment, fast project progress, excellent project quality, and wide applicability. During the tunnel boring machine (TBM) excavation, a combination of conventional battery-powered vehicles, dump trucks, mortar trucks, and segment trucks forms a "small train" to complete the tasks of excavation and segment transportation. This method features a high degree of mechanization and strong safety assurance.
[0003] According to the specification of Chinese Utility Model Publication No. "CN214240827U", "a track anti-runaway structure is provided with a plurality of anti-runaway components at the joint of two adjacent rail sections on the same side of the track. The anti-runaway component includes a telescopic component and two locking components. The telescopic component includes a lifting column, a fixed column, a steel plate and a spring. The lifting column has a partially hollow part inside. The upper end of the fixed column is fitted into the partially hollow part of the lifting column. The lower end of the fixed column is connected to the joint. The lower end of the lifting column is connected to the steel plate. The steel plate is connected to the upper end of the spring. The lower end of the spring is connected to the joint. One of the locking components includes a rotary bearing locking spring steel component and an electromagnetic coil locking device. The rotary bearing locking spring steel component and the electromagnetic coil locking device are respectively installed on the same side wall of two adjacent rail sections on the same side of the track. The electromagnetic coil locking device is connected to the central control equipment. The two locking components are symmetrically arranged on the two side walls of two adjacent rail sections on the same side of the track."
[0004] According to the aforementioned patent, in order to prevent electric vehicles from slipping during tunnel construction, it is necessary to install anti-slipping devices to limit the electric vehicles. However, existing anti-slipping devices require the movement of the pressure pin during use, which makes operation inconvenient. Utility Model Content
[0005] The purpose of this invention is to provide a track anti-runaway device to solve the problems mentioned in the background art.
[0006] The technical solution adopted in this utility model is: A track anti-slip device includes a limiting assembly: the limiting assembly includes: a transmission rod disposed on one side of the track and passing through the track; a disc symmetrically disposed on the transmission rod; a torsion spring symmetrically sleeved on the outside of the transmission rod, one end connected to the disc and the other end connected to the track; a stop bar disposed on the outside of the disc; limiting rods symmetrically disposed on the track; a connecting block disposed on the disc; and a stop block disposed on the top of the connecting block.
[0007] Optionally, the stop block is provided with an auxiliary component, the auxiliary component including: a rubber block disposed on the stop block.
[0008] Optionally, the auxiliary component further includes a sleeve disposed on the disk.
[0009] Optionally, the limiting rod is a screw.
[0010] Optionally, the auxiliary component further includes a rubber ring fitted around the outside of the stop lever.
[0011] Optionally, the connecting block is connected to the disk by bolts.
[0012] Optionally, the auxiliary component further includes: a docking block disposed on the disk; and a docking groove formed on the connecting block.
[0013] Optionally, the docking block is rectangular.
[0014] Compared with the prior art, the beneficial effects of this utility model are: When the wheel travels on top of the track and passes the top of the stop block, the stop block is tilted on one side, allowing it to be pressed down. Since the connecting block at the bottom of the stop block is connected to the disc, and one end of the torsion spring is connected to the disc while the other end is connected to the track, the stop block rotates when pressed down. After the wheel passes the stop block, which has no limiting mechanism, the torsion spring resets, and the stop block also resets and pushes out, thus blocking the backward-moving wheel. Simultaneously, the stop lever contacts the limiting rod to limit the stop block, preventing it from rotating while limiting the wheel and preventing slippage. This device has a simple structure, is easy to use, and facilitates wheel limiting to prevent slippage, making it more convenient to use. Attached Figure Description

[0018] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] Given the current technology, in order to prevent electric vehicles from slipping during tunnel construction, it is necessary to install anti-slipping devices to limit the electric vehicles. However, existing anti-slipping devices require the movement of the pressure pin during use, which makes operation inconvenient.
[0020] like Figure 1-3As shown, this utility model embodiment provides a track anti-slip device, including a limiting component 1: the limiting component 1 includes: a transmission rod 12 disposed on one side of the track 11 and passing through the track 11; a disc 13 symmetrically disposed on the transmission rod 12; a torsion spring 14 symmetrically sleeved on the outside of the transmission rod 12, one end connected to the disc 13 and the other end connected to the track 11; a stop bar 15 disposed on the outside of the disc 13; a limiting rod 16 symmetrically disposed on the track 11; a connecting block 17 disposed on the disc 13; and a stop block 18 disposed on the top of the connecting block 17.
[0021] When the wheel travels on top of the track 11 and passes the top of the stop block 18, the stop block 18 can be pressed down because one side of it is inclined. Since the connecting block 17 at the bottom of the stop block 18 is connected to the disc 13, and one end of the torsion spring 14 is connected to the disc 13 and the other end is connected to the track 11, the stop block 18 can be rotated when it is pressed down. After the wheel passes through the stop block 18, the stop block 18 has no limiting mechanism, so the torsion spring 14 will reset, and the stop block 18 will also reset and push out. This can block the backward wheel. At the same time, the stop bar 15 will contact the limiting bar 16 to limit the stop block 18 and prevent the stop block 18 from rotating when limiting the wheel to prevent it from slipping. The device has a simple structure, is easy to limit the wheel, and prevents the wheel from slipping, making it more convenient to use.
[0022] Furthermore, an auxiliary component 2 is provided on the stop block 18, the auxiliary component 2 including a rubber block 21 disposed on the stop block 18.
[0023] A rubber block 21 is provided on one side of the stop block 18. When the stop block 18 blocks the wheel, the rubber block 21 can reduce the impact on the stop block 18 and protect the stop block 18.
[0024] Furthermore, the auxiliary component 2 also includes a sleeve 22 disposed on the disk 13.
[0025] A sleeve 22 is provided on one side of the disc 13 so that the torsion spring 14 can be covered by the sleeve 22, thus preventing the torsion spring 14 from being exposed and protecting the torsion spring 14.
[0026] Furthermore, the limiting rod 16 is a screw.
[0027] The limiting rod 16 is set as a screw and threadedly connected to the rail 11. This allows the limiting rod 16 to be disassembled by screwing so that the damaged limiting rod 16 can be replaced.
[0028] Furthermore, the auxiliary component 2 also includes a rubber ring 23 fitted onto the outside of the stop bar 15.
[0029] A rubber ring 23 is fitted on the outer wall of the stop lever 15. When the stop lever 15 collides with the limit rod 16, the rubber ring 23 can reduce the impact on the stop lever 15 and protect the stop lever 15.
[0030] Furthermore, the connecting block 17 is connected to the disk 13 by bolts.
[0031] The connecting block 17 and the disc 13 are bolted together. This makes it easy to remove and replace the connecting block 17 if the stop 18 on the top of the connecting block 17 is damaged or deformed, so as not to affect subsequent use.
[0032] Furthermore, the auxiliary component 2 also includes: a docking block 24 disposed on the disk 13; and a docking groove 25 formed on the connecting block 17.
[0033] A mating groove 25 is made on one side of the connecting block 17, and a mating block 24 is set on one side of the disc 13. This allows the mating block 24 to mate with the mating groove 25 during subsequent installation, thus limiting the position of the mating block 24 so that it can be fixed and installed with bolts later.
[0034] Furthermore, the docking block 24 is rectangular.
[0035] Setting the mating block 24 to a rectangle prevents the connecting block 17 from tilting when the mating block 24 is in contact with the mating groove 25, so that it can be fixed with bolts later.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
