Description

Technical Field

[0001] The invention relates to the technical field of railway turnout devices, and in particular to a heavy-duty detachable turnout. Background Art

[0002] The suspended monorail turnout for coal mines is a turnout device used in the overhead monorail transportation system in coal mines. It is mainly composed of turnout points, frogs, connecting guide rails, steering mechanisms and other parts. It is used to transport coal, gangue, materials, equipment and personnel, especially in places where there are multiple mining faces or different transportation tunnels intersect. The suspended monorail turnout can effectively organize and guide transportation and improve the operating efficiency of the entire coal mine underground transportation system.

[0003] In daily use, during the switch switching process, the swing rail is connected to the car stop through a swing connecting rod. Since the swing rail is relatively long and connected to the car stop through swing connecting rods at both ends, and the middle part is suspended, this design may cause the middle part of the swing rail to deform during long-term use. For example, in a switch device for a monorail crane disclosed in CN109835368B, the swing rail lacks support for the middle part during the transportation of goods. Since the middle part of the swing rail lacks support, it may be deformed by vibration and external force during transportation during use, especially in the case of large loads or continuous transportation, coupled with the vibration and swing generated during the transportation of goods (whether it is a hanging rail or a swing rail, it will be affected by external forces or inertia during the transportation process, causing vibration), which may cause uneven force at the connection between the two ends and the swing connecting rod and the car stop, and the pressure may be concentrated at the connection point, resulting in looseness between the swing rail and the connecting rod or the car stop, thereby increasing safety hazards.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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] The present invention will be further described below in conjunction with the embodiments.

[0020] Example: Refer to Figures 1 to 9 , heavy-duty detachable turnouts, including: The turnout 1 comprises a support rail 108, and a swing rail 107 is arranged below the support rail 108; Adsorption and fixing component 3, a sliding plate 302 is arranged above the turnout 1, a plurality of sliding barrels 310 are fixedly installed in the sliding plate 302, the lower end of the sliding barrel 310 is connected with a conical barrel 311, an electromagnetic device 315 is fixedly installed on the outer wall of the conical barrel 311 and at a lower position, the electromagnetic device 315 is electrically connected to a controller, an elastic capsule 314 is slidably installed in the conical barrel 311, a magnetorheological fluid is arranged in the elastic capsule 314, when the swing rail 107 vibrates due to the movement of the vehicle, the elastic capsule 314 slides down in the conical barrel 311 and extrude to the bottom of the conical barrel 311 and increase the extrusion area, the electromagnetic device 315 acts on the elastic capsule 314 to generate magnetic adsorption to fix the swing rail 107 The elastic capsule 314 is a capsule made of rubber. When it is not squeezed out of the conical barrel 311, the elastic capsule 314 is stored in the conical barrel 311. When a small part of it is squeezed out of the conical barrel 311, most of the elastic capsule 314 can still stay in the conical barrel 311 for storage. The conical barrel 311 has a large inner diameter and a small outlet, which can prevent the elastic capsule 314 from falling out of the conical barrel 311 completely. In addition, the conical barrel 311 is made of iron. The magnetorheological fluid set in the elastic capsule 314 can also be adsorbed on the conical barrel 311 for fixation. The magnetorheological fluid is an existing material, mainly composed of magnetic particles (such as carbonyl iron powder), base liquid (such as mineral oil, silicone oil, etc.) and additives. In the absence of a magnetic field, the magnetic particles are randomly distributed in the base liquid and are in a liquid state as a whole; when there is a magnetic field, the magnetic particles will form a chain or columnar structure along the direction of the magnetic field, which will increase the viscosity of the material sharply, and appear to be a solid-like state on a macro scale, and have the function of transmitting a magnetic field.

[0028] The working principle of the present invention is as follows: When the goods travel to the swing rail 107, the swing rail 107 will vibrate. This is because both the hanging rail and the swing rail will be affected by external forces or inertia during the transportation process, causing vibration. This vibration is a normal phenomenon and has no effect on the transportation of goods. However, when the goods are transported for a long time and there is no fixed support in the middle of the swing rail 107, when the swing rail 107 and the linkage frame 102 and the car block become loose, the amplitude of the vibration generated by the swing rail 107 will increase. Especially when transporting heavier goods, the amplitude of this vibration will increase significantly, and when the goods are transported, the vibration amplitude will increase significantly. When an object enters the swing rail 107 through the hanging rail, the vibration generated by the swing rail 107 will cause the swing rail 107 to push the top rod 404 to slide in the fixed block 403, and the sliding fixed block 403 will drive the connecting round block 405 to compress the fifth spring 406 and drive the paddle 407 to move together, and the moving paddle 407 will contact the piezoelectric sensor 409 and make the piezoelectric sensor 409 vibrate. In the process of the piezoelectric sensor 409 generating vibrations, the generated vibrations will be converted into electrical signals, and the strength of the electrical signal generated by the piezoelectric sensor 409 is proportional to the vibration generated by the swing rail 107. The controller controls the current of the circuit 317 to change accordingly according to the received electrical signal (the piezoelectric sensor 409 works based on the piezoelectric effect. When subjected to external vibration, the lattice structure inside the piezoelectric material will be deformed, resulting in the relative displacement of the positive and negative charge centers, generating charges on the surface of the material, and forming electrical signals. The controller controls the current input to the electromagnet 317 by the strength of the electrical signal to make the electromagnet 317 generate magnetic forces of different strengths). In this way, the electromagnet 317 can generate a corresponding magnetic field according to the electrical signal generated by the piezoelectric sensor 409. It should be noted that since the swing rail 107 itself will generate vibrations during the transportation of goods, the vibration generated by the same controller does not require the operation of the lower frequency of the electrical signal generated by the piezoelectric sensor 409 (the piezoelectric sensor 409 generates different electrical signals through vibrations of different amplitudes, and the controller controls according to the set threshold value. The controller does not react to the vibration below the threshold). When the swing rail 107 vibrates above the threshold due to the looseness between the linkage frame 102 and the vehicle block, the controller performs corresponding control actions. The magnetic force generated by the electromagnet 317 will push the lifting plate 305 to slide and descend in the bracket 316. The sliding and descending lifting plate 305 will drive the second sliding bar 306 and the L-shaped sliding plate 304 to descend together. The multiple second sliding bars 306 set in the lifting plate 305 will descend at different heights in the lifting plate 305, and squeeze the pressure column 313 in turn. The squeezed pressure column 313 will drive the pressure rod 312 to slide and descend in the sliding barrel 310, and squeeze the elastic bag 314. The squeezed elastic bag 314 will be squeezed out from the lower end of the conical barrel 311 and continuously increase its area until it contacts the connecting plate 331. In the process of the lifting plate 305 being continuously driven to descend, the electromagnetic device 315 will contact the baffle 319, and squeeze the baffle 319 to compress the third spring 320 to drive the extrusion rod 321 to descend in the sliding sleeve 318, and the descending extrusion rod 321 will contact the slider 324, and squeeze the slider 324 to push the slider 324 and the top The block 325 moves and stretches the fourth spring 327, so that the top block 325 contacts and squeezes and fixes the second support block 301, thereby preventing the sliding plate 302 from moving during the adsorption of the elastic capsule 314 and the connecting plate 331, causing an error in the adsorption position. After the extrusion rod 321 squeezes the slider 324, the extrusion rod 321 contacts the trigger sensor 323. After the trigger sensor 323 is triggered again, it immediately transmits a signal to the controller, and the controller transmits an electric current to the electromagnetic device 315 to generate a magnetic field to control the magnetorheological fluid set in the elastic capsule 314 to produce magnetic adsorption to the connecting plate 331 installed on the swing rail 107 and solidify. At the same time, the magnetorheological fluid set in the elastic capsule 314 that is not squeezed out of the conical barrel 311 will also solidify. In this way, the conical barrel 311 and the connecting plate 331 will be magnetically adsorbed and connected and supported by the magnetorheological fluid set in the elastic capsule 314, thereby reducing the vibration of the swing rail 107 and making the transportation of goods more stable. When the swing rail 107 is swinging, the magnet 332 will attract the long plate 401 and move together, so that the adsorbed long plate 401 always swings with the two sides of the swing rail 107, so that the vibration amplitude of the swing rail 107 can be detected no matter which fork it switches to. During the swinging of the adsorbed long plate 401, the first slide bar 202 will move together with the adsorbed long plate 401 through the rotation connection with the adsorbed long plate 401, and slide in the first support block 204, stretching or compressing the first spring 203. The rotating head 205 will drive the first support block 204 to rotate to provide the sliding angle of the first slide bar 202. During the swinging and switching of the fork of the swing rail 107, the connecting plate 331 will be driven to move. The connecting plate 331 will drive the sliding plate 302 to rotate and adjust the angle in the second support block 301 through the rotating block 330, the connecting block 329 and the bottom block 328, so as to support the swing rail 107 after the swinging and switching of the fork.

[0029] After the goods move away from the swing rail 107, the compressed second spring 308 drives the lifting plate 305 to slide and rise again in the bracket 316, and the elastic bag 314 squeezed out of the conical barrel 311 will retract into the conical barrel 311 due to the elastic force of the elastic bag 314 itself.
