The locking shaft is in a dead point position in the locked state, and the locking is reliable, which effectively avoids the hidden danger of the flipping compensating rail tilting, and has high safety.

Description

Technical Field

[0001] The present invention belongs to the technical field of suspended monorail railways, and particularly relates to a locking device for a compensating rail of a suspended single turnout and a suspended single turnout. Background Art

[0002] Currently, a suspended single-rail turnout using the lifting switch technology generally includes a turnout beam, a movable rail disposed horizontally in the turnout beam along the horizontal direction of the turnout beam, a movable rail lifting device, and a movable rail switching device. In order to achieve the continuity of the turnout running surface and improve the riding comfort of the vehicle, two compensating rails are usually symmetrically arranged outside the movable rail in parallel.

However, when the vehicle passes through the turnout area, the vehicle guiding wheel will apply a lateral load to the compensating rail. If it exceeds the force range of the four-bar linkage during long-term use, it may cause the locking of the compensating rail by the four-bar linkage in the device to fail, resulting in serious safety problems such as the flipping of the compensating rail causing the running surface to warp.

[0036] It should be noted that the locking device for the suspension single-rail turnout compensating rail provided in the embodiment of the present invention is applied to a suspension single-rail turnout. Generally, in a suspension single-rail turnout, the turnout beam is a beam body for supporting the turnout and vehicle switching in the suspension single-rail turnout (not shown in the attached drawings of the embodiment of the present invention), the turnout beam is a beam body with a lower opening, the main body of the turnout beam is formed by connecting a single-rail beam and a double-rail beam, and the movable rail 1 is arranged parallel to the turnout beam in the single-rail beam and one end is connected with the intersection of the double-rail beam. In order to achieve the continuity of the turnout running surface and improve the vehicle passing comfort, two compensating rails 2 are usually symmetrically arranged in parallel to the outside of the movable rail 1 in the single-rail beam. The core idea of the embodiment of the present invention is to lock or unlock the two compensating rails 2 while the movable rail 1 performs a lifting action, and reduce the safety risk of the running surface warping in the turnout.

[0037] Among them, the lifting crank assembly 4 is a component used to drive the rotation of the locking crank assembly 5 through the lifting crankshaft 401 and the multi-link structure. The two lifting crank bearing seats 402 in the lifting crank assembly 4 are symmetrically installed on the switch beam with the center line of the switch beam as the center. The two lifting crank bearing seats 402 can be installed by bolts, buckles or welding, as long as the installation of the lifting crank bearing seats 402 is stable. The embodiments of the present invention do not make specific limitations on this.

[0038] Both ends of the lifting crankshaft 401 pass through the two lifting crank bearing seats 402 respectively. The lifting crankshaft 401 and the lifting crank bearing seats 402 can be connected by clearance fit or by means of a bearing fastening sleeve. The power crank arm 403 is arranged at the axial center position of the lifting crankshaft 401, and the first crank arm 404 is arranged on the lifting crankshaft 401 beside the power crank arm 403. The power crank arm 403 and the first crank arm 404 arranged on the lifting crankshaft 401 can be integrally formed with the lifting crankshaft 401, or can be fastened on the lifting crankshaft 401 by means of key connection, interference connection, etc.

[0039] Among them, the locking crank assembly 5 is a device used to change the rotational motion into a linear motion through the locking crankshaft 501 and the multi-link structure, so as to lift the locking assembly 6 to lock and unlock the compensating rail 2. The two locking crank bearing seats 502 are symmetrically installed on the switch beam with the center line of the switch beam as the center. The two locking crank bearing seats 502 can be installed by bolts, buckles or welding, as long as the installation of the locking crank bearing seats 502 is stable. The embodiments of the present invention do not make specific limitations on this. Both ends of the locking crankshaft 501 pass through the two locking crankshaft 501 bearing seats respectively. The locking crankshaft 501 and the two locking crank bearing seats 502 can be connected by clearance fit or by means of a bearing fastening sleeve. After the locking crankshaft 501 passes through the two locking crank bearing seats 502, linkage crank arms 504 are respectively arranged at both ends. The linkage crank arms 504, the locking crank arms 503, the power crank arms 403 and the first crank arms 404 have the same shape, and the sizes can be the same or different, as long as it can be ensured that when the lifting crankshaft 401 rotates, the locking crankshaft 501 rotates synchronously and drives the locking assembly 6 to move up and down. The embodiments of the present invention do not make specific limitations on this.

[0040] Among them, the locking component 6 is a device for locking the compensation rail 2. The two locking components 6 respectively correspond to the linkage crank arms 504 at both ends of the locking crankshaft 501, and are respectively connected to the corresponding linkage crank arms 504 through tie rods. The locking component 6 includes a locking seat 601, a locking shaft 602 and a locking baffle 603. In addition, the locking seat 601 can be merely a seat body with a circular hole in the center, and is fixedly arranged on the side wall of the turnout beam by means of welding, bolt connection, clamping, etc. The locking shaft 602 is movably arranged in the circular hole of the locking seat 601 to realize up and down movement in a fixed vertical plane. The locking seat 601 can also be a structure of a seat body and a sliding sleeve 6012. On the basis of completely restricting the up and down movement path of the locking shaft 602 through the sliding sleeve 6012, and the sliding sleeve 6012 is made of a material with low frictional resistance, which can reduce the moving frictional force of the locking shaft 602 and improve the moving flexibility.

[0041] Figure 3 is a perspective view of the locking seat 601 in a hanging single-track turnout compensation rail locking device provided by an embodiment of the present invention, as Figure 3 shown. In a possible embodiment, the locking seat 601 includes a locking mounting seat 6011 and a sliding sleeve 6012; the locking mounting seat 6011 is vertically and fixedly mounted on the side wall of the turnout beam, the sliding sleeve 6012 is connected to the locking mounting seat 6011, and the locking shaft 602 is movably arranged in the sliding sleeve 6012. Specifically, the locking mounting seat 6011 is vertically fixed to the side wall of the turnout beam by means of welding, bolt connection, etc. A circular hole is opened in the center of the locking mounting seat 6011. One end of the sliding sleeve 6012 passes through the circular hole of the locking seat 601 and is fixedly connected to the locking mounting seat 6011. The other end of the sliding sleeve 6012 is vertically fixed to the side wall of the turnout beam through a flange plate 6013. The locking shaft 602 is arranged in the sliding sleeve 6012 and slides up and down in the sliding sleeve 6012 under the drive of the tie rod.

[0042] In addition, one end of the locking shaft 602 away from the locking baffle 603 is an articulated structure connected to the tie rod, and one end close to the locking baffle 603 is circular or has planar surfaces cut on both sides. In a possible implementation manner, in order to increase the contact area between the lower end of the locking shaft 602 and the locking baffle 603 and improve the locking strength, one end of the locking shaft 602 close to the locking baffle 603 can also be a D-shaped shaft structure or a rod-shaped structure. The locking baffle 603 can be fixed to the compensation rail 2 by means of welding or bolt connection. One end of the locking baffle 603 in contact with the locking shaft 602 is a planar structure.

[0043] Among them, the power push rod 3 is the power source of the locking device for the suspended single-track turnout compensating rail 2. The power push rod 3 can be an electric push rod or a hydraulic cylinder linear drive unit, and the power push rod 3 makes a linear reciprocating motion. The power push rod 3 is hinged to the power crank arm 403. The power push rod 3 can be directly fixedly installed on the turnout beam, or can be fixedly installed on the turnout beam through the cross beam assembly and the base of the power push rod 3. In a specific embodiment, the lifting device for the movable rail 1 of the suspended single-track turnout further includes a cross beam assembly fixedly installed on the turnout beam, the base of the power push rod 3 is fixedly installed on the cross beam assembly, and the power push rod 3 is connected to the base of the power push rod 3 through a pin shaft.

[0044] When the above-mentioned embodiment works, the power push rod 3 makes a linear reciprocating motion to drive the lifting crank shaft 401 of the lifting crank assembly 4 to rotate. The first crank arm 404 drives the locking crank shaft 501 in the locking crank assembly 5 to rotate synchronously through a pull rod. The linkage crank arm 504 on the rotating locking crank shaft 501 drives the locking shaft 602 in the locking assembly 6 to rise or fall through a pull rod. When the locking shaft 602 rises to the highest point, the locking device for the suspended single-track turnout compensating rail 2 unlocks the compensating rail 2, and the compensating rail 2 can be turned over; when the locking shaft 602 descends to the lowest point, the locking device for the suspended single-track turnout compensating rail 2 locks one end of the compensating rail 2, and the compensating rail 2 is in a locked state and cannot be turned over. In the locked state, the locking shaft 602 is in the dead point position, the locking is reliable, effectively avoiding the occurrence of the hidden danger of the flip-type compensating rail 2 warping, and the safety is high.

[0045] It should also be noted that in the above-mentioned embodiment, only two locking assemblies 6 respectively lock one end of the two compensating rails 2. In another possible implementation manner, in order to improve the locking strength and prevent the locking failure of the compensating rail 2 to a greater extent, a set of locking crank assemblies 5 with the same structure as the above-mentioned embodiment and a set of locking assemblies 6 can also be provided, and the two ends of the compensating rail 2 are locked simultaneously by the two locking crank assemblies 5 and the two sets of locking assemblies 6.

[0046] Specifically, the number of the locking crank assemblies 5 in the locking device for the suspended single-track turnout compensating rail 2 is two, the number of the locking assemblies 6 is four, and a second crank arm 405 is further arranged on the lifting crank shaft 401; the two locking crank assemblies 5 are respectively located at both ends of the power push rod 3. The locking crank arm 503 in the locking crank assembly 5 located at the first end of the power push rod 3 is hinged to the first crank arm 404 through a pull rod, and the locking crank arm 503 in the locking crank assembly 5 located at the second end of the power push rod 3 is hinged to the second crank arm 405 through a pull rod; the four locking assemblies 6 are divided into two groups and are respectively located below both sides of the two locking crank assemblies 5, and the four locking assemblies 6 are divided into two groups to realize the synchronous locking of both ends of the two compensating rails 2.

[0047] It should be noted that the structures and operating principles of the two locking crank assemblies 5 and the four locking assemblies 6 located at both ends of the power push rod 3 are the same as those of the locking crank assembly 5 and the two locking assemblies 6 in the above embodiment. Only on the basis of the above embodiment, by adding a locking crank assembly 5 and two locking assemblies 6 to the other end of the power push rod 3, the effect of simultaneously locking or unlocking both ends of the two compensation rails 2 is achieved. The specific structures of the two locking crank assemblies 5 and the two groups of locking assemblies 6 are not described in detail in the embodiments of the present invention here.

[0048] It should also be noted that for the second locking crank assembly 5 and since the resistance is relatively large during the unlocking and lifting process of the locking shaft 602, the pull rod is in a tensile state at this time, which is more beneficial to the force on the pull rod. The resistance during the falling and locking process of the locking shaft 602 is relatively small, and the pull rod is in a thrust state at this time. In the thrust state, if the pull rod is too long, uneven force may cause the pull rod to be damaged. Therefore, in order to reduce the force intensity of the pull rod and improve the service life of the pull rod, the suspension single-track turnout compensation rail 2 locking device further includes a swing arm assembly 7; the swing arm assembly 7 includes a swing arm crank 701 and a swing arm base 702. The swing arm base 702 is fixedly installed on the turnout beam. The first end of the swing arm crank 701 is hinged to the swing arm base 702, and the second end of the swing arm crank 701 is hinged to the second crank arm 405 and the locking crank arm 503 located at the second end of the power push rod 3 through two pull rods respectively.

[0049] In addition, to accurately control the operation of the power push rod 3, the suspension single-track turnout compensation rail locking device further includes a controller 8. The controller 8 is used to control the power push rod 3 to perform linear reciprocating motion according to the received suspension single-track turnout switching signal. The controller 8 can be separately arranged outside the power push rod 3 and control the movement of the power push rod 3 through electrical connection, or can be integrated inside the power push rod 3 to save the space of the device. The controller 8 can receive the suspension single-track turnout switching control signal in a wired manner, or can receive the suspension single-track turnout switching control signal through an integrated communication module by means of wireless communication such as WIFI, Bluetooth, 4G, 5G signals, etc. The controller 8 can also determine whether the power push rod 6 is pushed out or retracted in place by obtaining the movement duration of the power push rod 3, obtaining the thrust value of the power push rod 3, etc. When the controller 8 receives the switching signal of the movable rail 1, it synchronously controls the movement of the power push rod 3 to achieve the locking of the two compensation rails 2.

[0050] When the above-mentioned invention embodiment is working, the suspension single-track switch signal received by the controller 8 controls the power push rod 3 to perform a linear reciprocating motion. The power push rod 3 performing a linear reciprocating motion drives the lifting crank shaft 401 of the lifting crank assembly 4 to rotate. The first crank arm 404 and the second crank arm 405 provided on the lifting crank shaft 401 respectively drive the locking crank shafts 501 in the two locking crank assemblies 5 located at both ends of the power push rod 3 to rotate synchronously through tie rods. The two rotating locking crank shafts 501 respectively drive the locking shafts 602 in the corresponding locking assemblies 6 to rise or fall through tie rods. As Figure 4 shown, when the two groups of locking shafts 602 descend to the lowest point, the locking device of the suspension single-track switch compensating rail 2 locks both ends of the two compensating rails 2. At this time, both ends of the two compensating rails 2 are in a locked state and cannot be flipped. As Figure 5 shown, when the two groups of locking shafts 602 rise to the highest point, the locking device of the suspension single-track switch compensating rail 2 unlocks the two compensating rails 2. At this time, the compensating rails 2 can be flipped. Since when locking the compensating rails 2, both ends of the two compensating rails 2 are locked synchronously, the locking strength is improved, the locking reliability is enhanced, and the safety of the device is further improved.

[0051] In a possible embodiment, the locking device for the suspension single-track switch compensating rail provided by the embodiment of the present invention is applied to a suspension single-track switch, and together with the movable rail switch device and the movable rail lifting device in the suspension single-track switch, a suspension single-track switch system is formed to realize the functions of lifting, switching, and locking of the movable rail. In this suspension single-track switch, the movable rail switch device is connected to the movable rail and is used to switch the movable rail; the movable rail lifting device is connected to the lifting crank assembly. When the movable rail lifting device lifts the movable rail, the locking device of the suspension single-track switch compensating rail unlocks the compensating rail in the suspension single-track switch, and when the movable rail lifting device lowers the movable rail, the locking device of the suspension single-track switch compensating rail locks the compensating rail in the suspension single-track switch.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
