DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The technical solution provided by the embodiments of the present invention is described in detail below with reference to the accompanying drawings.

[0023] The embodiment of the present invention provides a shear type wheel stopper, as shown in the attached Figure 1 and attached Figure 2 As shown, it includes: a driving device 1, a connecting rod 2, an arc plate 3, a wheel stopper body 4 and a side plate 5; one end of the connecting rod 2 is connected to the driving device 1, and the other end is connected to one end of the arc plate 3, and performs reciprocating linear motion under the drive of the driving device 1; a rotating shaft 6 is passed through the arc plate 3, and the arc plate 3 can rotate around the rotating shaft 6; the other end of the arc plate 3 is connected to the wheel stopper body 4 through a shear bolt 7, and the wheel stopper body 4 can be rotated onto the rail 8 or flipped down the rail 8 under the drive of the arc plate 3; the side plate 5 is connected to the wheel stopper body 4, and when the wheel stopper body 4 rotates onto the rail 8, the side plate 5 is stuck on the rail 8.

[0024] The working principle of the shear type wheel stopper provided in the embodiment of the present invention is described below:

[0025] When in use, the driving device 1 provides driving force to drive the connecting rod 2 to perform reciprocating linear motion. One end of the arc plate 3 is connected to the connecting rod 2, and the other end is connected to the wheel stopper body 4, and a rotating shaft 6 is penetrated in the middle of the arc plate 3, which can rotate around the rotating shaft 6. When one end of the arc plate 3 performs reciprocating linear motion under the drive of the connecting rod 2, the other end drives the wheel stopper body 4 to rotate, so that the wheel stopper body 4 rotates onto the rail 8 or flips off the rail 8. When the wheel stopper body 4 flips off the rail 8, it does not interfere with the operation of the locomotive. When the wheel stopper body 4 rotates onto the rail 8, it enters the working state and plays the role of stopping the car and stopping the wheel. In the process of stopping the car and stopping the wheel, the locomotive has a large force on the wheel stopper body 4. When it exceeds the shear force of the shear bolt 7, the shear bolt 7 is cut off, the wheel stopper body 4 and the arc plate 3 are disconnected, and the wheel stopper body 4 slides on the rail 8 to generate sliding friction, and the locomotive is gradually stopped by friction. The movement of the wheel stopper will not cause damage to the transmission parts (connecting rod 2 and arc plate 3, etc.). By connecting the side plate 5 to the wheel stopper body 4, the side plate 5 is clamped on the rail 8, which plays a limiting role on the wheel stopper body 4, preventing the wheel stopper body 4 from detaching from the rail 8 during the sliding process. After a wheel stopping process is completed, a new shear bolt 7 is replaced to connect the wheel stopper body 4 and the arc plate 3 together, and the reset is completed, preparing for the next wheel stopping process.

[0026] It can be seen that in the shear-type wheel stopper provided in the embodiment of the present invention, the driving device 1 drives the wheel stopper body 4 to rotate through the transmission component, and the working position of the wheel stopper body 4 can be controlled more conveniently. By using the shear bolt 7 to connect the wheel stopper body 4 with the transmission component, the transmission component is not damaged during use, and the reset process is simple and convenient. By setting the side plate 5 stuck on the rail 8, the wheel stopper body 4 is limited to avoid separation from the rail 8. The structure is reasonable, the operation is convenient, and the stability and safety are high.

[0027] In the embodiment of the present invention, the driving device 1 is used to provide driving force. The structure of the driving device 1 is described as follows:

[0028] As attached Figure 1 As shown, the driving device 1 includes: an electric switch machine 101, a telescopic rod 102 and a tie rod bracket 103; the electric switch machine 101 is used to output power; one end of the telescopic rod 102 is connected to the electric switch machine 101, and the other end is connected to one end of the tie rod bracket 103, and the other end of the tie rod bracket 103 is connected to one end of the connecting rod 2.

[0029] With such arrangement, the electric switch machine 101 drives the telescopic rod 102 to extend and retract, thereby driving the pull rod bracket 103 and the connecting rod 2 to perform reciprocating linear motion.

[0030] Furthermore, the shear-type wheel stopper also includes a dispatching visual platform, which is used to control the operation of the electric switch machine 101. In this way, the dispatching visual platform controls the power on and off of the electric switch machine 101 and the operation of the motor of the electric switch machine 101 according to the obtained locomotive operation information and the operation instructions input by the staff, so as to realize the remote automatic control of the turning process of the wheel stopper body 4, avoid safety accidents caused by the harsh working environment on site, etc., with high safety and reduced labor intensity.

[0031] Optionally, the driving device 1 may also be a motor or a telescopic cylinder, etc., as long as it can drive the connecting rod 2 to perform reciprocating linear motion.

[0032] Optionally, as attached Figure 1 As shown, the shear type wheel stopper provided in the embodiment of the present invention further includes a fixed bracket 9 and a fixed plate 10; the fixed bracket 9 is connected to the fixed plate 10, and the fixed plate 10 is fixed on the side wall of the rail 8; the rotating shaft 6 is arranged on the fixed bracket 9.

[0033] By setting a fixed bracket 9 and a fixed plate 10 fixed relatively to the rail 8, a mounting base is provided for the rotating shaft 6. It can also serve as a positioning reference for the connecting rod 2 and the arc plate 3, so that the connecting rod 2 and the arc plate 3 can move within a preset degree of freedom, avoid random shaking, and improve stability.

[0034] The fixing bracket 9 and the fixing plate 10 can be fixed by welding, and the fixing plate 10 can be fixed on the waist of the rail 8 by a plurality of bolts. Figure 2 As shown, there are four bolts, which are evenly distributed on the same horizontal line to fix the fixing plate 10 on the waist of the rail 8 .

[0035] Optionally, the telescopic rod 102 is connected to the rod bracket 103 by bolts; and / or the rod bracket 103 is connected to the connecting rod 2 by bolts; and / or the connecting rod 2 is connected to the arc plate 3 by bolts. Bolt connection facilitates disassembly and assembly, and thus facilitates the inspection and replacement of various components. Alternatively, the connection of the above ends can also be welded, hinged or clamped, as long as the transmission can be achieved and the use requirements are met.

[0036] In the embodiment of the present invention, the rod bracket 103 performs reciprocating linear motion driven by the telescopic rod 102. Optionally, the rod bracket 103 is connected with a slideway 11, and the fixed bracket 9 is provided with a groove adapted to the slideway 11, so as to make the rod bracket 103 slide and cooperate with the fixed bracket 9. In this way, the rod bracket 103 is limited without affecting the transmission effect of the rod bracket 103, so as to avoid the deflection and shaking of the rod bracket 103, thereby improving stability and safety in use.

[0037] Furthermore, in order to facilitate the relative sliding of the pull rod bracket 103 and the fixed bracket 9, a pulley can be installed outside the slideway 11 to convert the sliding friction into rolling friction and reduce the friction resistance.

[0038] During use of the shear type wheel stopper provided in the embodiment of the present invention, the arc plate 3 needs to maintain a certain gap with the rail 8 so that the rail 8 does not interfere with the rotation of the arc plate 3. The wheel stopper body 4 is located above the rail 8 to stop the vehicle and the wheel. Based on the above, as shown in the attached Figure 1 As shown, a first connecting plate 12 and a second connecting plate 13 are arranged between the arc plate 3 and the wheel stopper body 4; the arc plate 3 and the first connecting plate 12 are connected by shear bolts 7, the first connecting plate 12 is partially overlapped on the second connecting plate 13, and the second connecting plate 13 is fixed on the wheel stopper body 4. In this way, the wheel stopper body 4 and the arc plate 3 can be connected together, and an axial gap can be maintained between the two in space, and their respective positions can meet the use requirements.

[0039] In the embodiment of the present invention, the wheel stopper body 4 is used to act with the wheel to stop the vehicle and the wheel. The structure of the wheel stopper is described as follows:

[0040] As attached Figure 1 As shown, the part of the wheel stopper body 4 that contacts the wheel is an arc-shaped structure. The arc-shaped structure is a straight line segment below the same side, so that the arc-shaped structure is kept at a preset height to adapt to the wheel and make the wheel and the wheel stopper body 4 contact better. The other side of the wheel stopper body 4 is an oblique line segment, which ensures the stability and strength of the wheel stopper body 4 and can save materials.

[0041] The radius of the arc-shaped structure of the wheel stopper body 4 can be set according to the size of the wheel. For example, the radius can be 92 cm.
