Description

Technical Field

[0001] The invention relates to the field of car arresters, in particular to a new type of car arrester used in mines. Background Art

[0002] The car blocker is a common production tool in mine production. It is mainly used in the transportation system. It is one of the important facilities in the coal mine transportation system and is an anti-runaway device. The car blocker is generally installed at the top of the slope. On the one hand, it limits the mine car to stay in the specified position, and on the other hand, it is used to prevent runaway accidents. It is often used in conjunction with equipment such as pushers, dumpers, crawlers, cages, and dispatch winches.

[0003] At present, many types of car arresters are used in mines. The opening and closing of the car arrester are controlled by pneumatic or other means. When in use, the frame of the car arrester sinks into the foundation pit, and the pneumatic components or other types of control components sink into the box. There are coal, soil, water and other substances in the foundation pit, which cause corrosion of the control components, affecting the use and limited life. When the car arrester is in use, it will produce large torque and shear force due to collision. Long-term stress can easily cause metal fatigue of the shaft connected to the car arrester, resulting in irreversible deformation, reducing the car arresting effect or even failure, affecting driving safety. Summary of the invention

[0004] In order to solve the problem that the blocking block of the car blocker in the prior art is subjected to long-term collision, causing its connecting shaft to deform and affect the car blocking effect, the present invention proposes a new type of car blocker.

[0005] The technical solution of the present invention is achieved in this way: A novel car blocker comprises: a channel steel bracket and a car block assembly, wherein the channel steel bracket is fixed under the track, and car block assemblies located outside the track are respectively arranged on both sides of the channel steel bracket, and the car block assembly comprises a U-shaped plate, a car block base, a car block block, a buffer shaft body, a buffer spring and a pneumatic mechanism, wherein the U-shaped plate is fixed on the channel steel bracket, and the car block base is slidably arranged on two buffer shaft bodies and located on the U-shaped plate body, and the two ends of the two buffer shaft bodies are fixed on both sides of the U-shaped plate body, and a buffer spring is arranged on the buffer shaft body between the car block base and the U-shaped plate body, and the car block block is connected to the car block base through a car block rotating shaft, and the two buffer shaft bodies are located below the car block rotating shaft and are arranged coaxially therewith, and the pneumatic mechanism is fixed on the car block base and located on one side thereof for driving the car block rotating shaft and the car block block to rotate; After the car stopper is hit, the force acts directly on the car stopper, which is transmitted to the car stopper base through the car stopper shaft. The car stopper base slides along the buffer shaft to compress the buffer spring on one side, generating tension on the buffer spring on the other side. At the same time, sliding friction is generated between the car stopper base and the U-shaped plate to improve the buffering performance.

[0006] Preferably, the two buffer shaft bodies are arranged in parallel, and the two buffer shaft bodies and the wheel-blocking shaft form an isosceles triangle shape or an equilateral triangle shape.

[0007] Preferably, the channel steel bracket includes two C-shaped channel steels and two I-shaped channel steels, the two I-shaped channel steels are arranged in parallel and fixed between the two C-shaped channel steels, the two C-shaped channel steels are arranged opposite to each other, and the two I-shaped channel steels are installed under the two rails through the track clamps; the U-shaped plate body is slidably arranged between the two C-shaped channel steels and connected thereto.

[0008] Preferably, at both ends of the two C-shaped channel steels, one or more connection holes are provided, which are respectively used to connect with the two U-shaped plate bodies to adjust the interval between the two U-shaped plate bodies.

[0009] Preferably, the pneumatic mechanism is configured as a rotary cylinder.

[0010] Preferably, the vehicle blocking base includes two side plates and a bottom plate, the two side plates are arranged opposite to each other with a certain interval and fixed on the bottom plate; The U-shaped plate body is located below the bottom plate, the buffer shaft body slides through the two side plates, the anti-car rotating shaft is rotatably arranged on the two side plates, one side of the anti-car rotating shaft extends out of the side plate on that side and is connected to the pneumatic mechanism through a flange.

[0013] Preferably, a fixed plate body is connected between the C-shaped channel steels located outside each I-shaped channel steel, and the U-shaped plate body is arranged on the fixed plate body.

[0014] The beneficial effects of the present invention are as follows: the new type of car blocker of the present invention, the two car block rotating shafts respectively drive the connected car block blocks to open or close under the action of two pneumatic shafts. After the car block blocks are hit, the generated force is distributed on the car block rotating shaft, the car block base, the buffer spring and the U-shaped plate. The car block base slides along the buffer shaft under the force and acts on the buffer springs on its front and rear sides. At the same time, the car block base and the U-shaped bottom plate generate sliding friction to provide support and friction. The car block rotating shaft and the two buffer shafts form a triangular stability, which improves the uniformity and stability of the force distribution and improves the stability effect and buffering performance of the car block assembly. In addition, the pneumatic mechanism is arranged on the car block base to slow down the speed at which it is corroded by water, coal and other substances in the foundation pit, thereby extending its service life.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0019] like Figure 1 and Figure 2A new type of car blocker shown in the figure includes: a channel steel bracket 1 and a car block assembly 2, the channel steel bracket 1 is fixed under the track, and the two sides of the channel steel bracket 1 are respectively provided with car block assemblies 2 located outside the track, the car block assembly 2 includes a U-shaped plate body 21, a car block base 22, a car block block 23, a buffer shaft body 24, a buffer spring 25 and a pneumatic mechanism 26, the U-shaped plate body 21 is fixed on the channel steel bracket, the car block base 22 is slidably arranged on two buffer shaft bodies 24 and is located on the U-shaped plate body 21, the two ends of the two buffer shaft bodies 24 are fixed on both sides of the U-shaped plate body 21, and a buffer spring 25 is arranged on the buffer shaft body 24 located between the car block base 22 and the U-shaped plate body 21, the car block block 23 is connected to the car block base 22 through a car block rotating shaft 27, the two buffer shaft bodies 24 are located below the car block rotating shaft 27 and are coaxially arranged therewith, and the pneumatic mechanism 26 is fixed on the car block base 22 and is located on one side thereof for driving the car block rotating shaft and the car block to rotate.

[0020] The two sides of the channel steel bracket 1 are respectively provided with a car-blocking assembly 2, and the two car-blocking blocks 23 of the two car-blocking assemblies 2 are respectively opened or closed under the drive of the pneumatic mechanism, and the pneumatic mechanism 26 drives the car-blocking shaft 27 to which the car-blocking block 23 is fixedly connected, and the two buffer shafts connecting the car-blocking base and the U-shaped plate are located below the car-blocking shaft, forming a triangular stability, and the torque and shear force generated by the collision of the car-blocking block are distributed on the car-blocking shaft, the car-blocking base, the buffer shaft, the buffer spring and the U-shaped plate, and the car-blocking block is transmitted to the car-blocking base through the car-blocking shaft, and the car-blocking base slides along the buffer shaft to compress the buffer spring on one side, and generates a pulling force on the buffer spring on the other side, and at the same time, a sliding friction is generated between the car-blocking base and the U-shaped plate, so as to improve the buffering performance. The overall force of the car-blocking assembly is relatively stable, and the strength of the channel steel bracket is large, which can greatly slow down the deformation of the car-blocking shaft, improve the stability of use, and extend the service life.

[0021] The pneumatic mechanism is arranged on the vehicle blocking base, which can slow down the speed of the pneumatic mechanism sinking in the foundation pit and being corroded by water, coal and other substances, and prolong its service life. In practice, it can reduce the number of maintenance and extend the service life.

[0022] like Figure 1 As shown, the two buffer shafts 24 are arranged in parallel, and the two buffer shafts 24 and the wheel stop shaft form an isosceles triangle shape or an equilateral triangle shape, so that the force distribution is more uniform. After the wheel stop assembly is subjected to force, it is avoided that the force is concentrated on the wheel stop shaft, thereby increasing the stability of use.

[0023] like Figure 3As shown, the channel steel bracket 1 includes two C-shaped channel steels 11, two I-shaped channel steels 12 and a fixing plate 15. The two I-shaped channel steels 12 are arranged in parallel and fixed between the two C-shaped channel steels 11. The two C-shaped channel steels 11 are arranged opposite to each other. The two I-shaped channel steels 12 are installed under two rails through a rail clamp 13. A fixing plate 15 is connected between the C-shaped channel steels located outside each I-shaped channel steel. Figure 1 and Figure 2 The U-shaped plate 21 is arranged on the fixed plate body 15 and can be pulled along the two C-shaped channel steels. The two sides of the U-shaped plate body are respectively connected to the two sides of the C-shaped channel steels. One or more connecting holes 14 are arranged at both ends of the two C-shaped channel steels 11, which are respectively used to connect with the two U-shaped plate bodies 21 and adjust the interval between the two U-shaped plate bodies 21.

[0024] The structure of the channel steel bracket 1 is simple, which is convenient for overall installation and hoisting installation, and is simple and quick to install in a mine. A slide groove is formed between the two C-shaped channel steels of the channel steel bracket 1, and the U-shaped plate body of the car-blocking assembly is arranged between the two C-shaped channel steels. The U-shaped plate body can slide along the inner side of the C-shaped channel steel, and can be installed and disassembled by pulling out. After the car-blocking block is subjected to the impact force, the sliding friction between the U-shaped plate body and the car-blocking base is generated due to sliding, which can play a buffering and vibration reduction role, so that the force applied to the car-blocking assembly is distributed as a whole, and the stability of use is improved. Moreover, the U-shaped plate body of the car-blocking assembly is connected to the channel steel bracket, which is convenient to install by pulling out, and it is also convenient to adjust the interval between the two car-blocking assemblies.

[0025] The pneumatic mechanism of the present invention is configured as a rotating cylinder, which can open the car block more than 180 degrees, so that the car block is completely located outside the car block base and below the height of the car block base after opening, so as to avoid the car block being too high to block some vehicles passing through the car blocker, thereby improving the adaptability of the car blocker. The chassis of the flatbed truck in the coal mine is relatively low, and the chassis is pressed even lower when transporting equipment. In some existing car blockers, the car block will hit the chassis of the flatbed truck when the flatbed truck passes by. The rotating cylinder is combined with other structures of the combined assembly to reduce the height of the car block after opening.

[0026] like Figure 1 As shown, the car blocking base 22 includes two side plates and a bottom plate, the two side plates are arranged oppositely and have a certain interval and are fixed on the bottom plate, the bottom plate is located on the U-shaped plate body, the buffer shaft body slides through the two side plates, the car blocking shaft is rotatably arranged on the two side plates, one side of the car blocking shaft extends out of the side plate on this side, and is connected to the pneumatic mechanism 26 through the flange 29. A limiting base 28 is arranged on the bottom plate at the side where the car blocking block is opened, which is used to support and limit the car blocking block after opening, to prevent the car blocking block from having too much impact force when opening or closing due to inertia, and has a buffering and limiting function for the opened car blocking block.

[0027] A bonded rubber layer is provided on the collision end of the car stopper, which can effectively reduce the collision sparks generated by the collision and play a buffering role, and can also play an anti-corrosion role to a certain extent.

[0028] When in use, the channel steel bracket is sunk into the foundation pit below the track. When the ordinary car blocker is sunk and installed, the size of the foundation pit is much larger than the overall size of the car blocker. When the novel car blocker of the present invention is sunk and installed, it can be directly hoisted, or it can be directly installed after the two C-shaped channel steels and two I-shaped channel steels of the channel steel bracket are sunk respectively. It only needs to weld the two I-shaped channel steels between the two C-shaped channel steels, and weld the fixed plate body. The size of the foundation pit can be achieved when it is appropriate, thereby improving the installation efficiency and saving the installation cost. When installing the car blocker assembly, the car blocker assembly can first install the U-shaped plate body on the channel steel bracket, adjust the interval between the two U-shaped plate bodies, and then install the other structures of the car blocker assembly on the U-shaped plate body. It can also be installed on the channel steel bracket after the car blocker assembly is installed. It is very convenient to install and disassemble during use, which not only saves installation and disassembly time, but also facilitates daily maintenance.

[0029] The pneumatic mechanism of the car-blocking assembly is connected to the pneumatic source under the mine. The two pneumatic mechanisms drive the two car-blocking shafts to rotate at the same time. The two car-blocking shafts drive the connected car-blocking blocks to open or close respectively. After the car-blocking blocks are hit, the forces generated are distributed on the car-blocking shafts, the car-blocking base, the buffer shaft, the buffer spring and the U-shaped plate. The friction buffering force is generated between the car-blocking base and the U-shaped plate due to sliding. The car-blocking base slides on the two buffer shafts and compresses the buffer spring on one side and stretches the buffer spring on the other side. The car-blocking shaft and the two buffer shafts form a stable triangle, which improves the uniformity and stability of the force distribution, and improves the stability and buffering effect of the entire car-blocking assembly. The channel steel bracket is strong and durable, and will not cause deformation between the C-shaped channel steels after the car-blocking assembly is hit.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
