[0039] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Figure 1 It is a perspective view of a suspension single-rail switch guide rail locking device provided by an embodiment of the present invention, Figure 2 It is a perspective view of a suspension single-rail switch guide rail locking device provided by an embodiment of the present invention installed on a suspension single-rail switch. See Figure 1 and Figure 2A suspension single-track switch guide rail locking device includes a switch beam 1 and a guide rail 2, and further includes a power push rod 4, a driving rotating shaft 5, two vertical connecting rods 6, two torsion arms 7, two horizontal connecting rods 8, and two locking hooks 9. A push rod swing arm 501 is provided at the center position of the driving rotating shaft 5, and lifting arms 502 are respectively provided at both ends of the driving rotating shaft 5. The driving rotating shaft 5 is installed on the top of the switch beam 1 through two bearing seats 503. The power push rod 4 is installed on the top of the switch beam 1, and the end of the push rod of the power push rod 4 is hinged to the push rod swing arm 501. The lifting arms 502 at both ends of the driving rotating shaft 5 are respectively hinged to the first ends of the two vertical connecting rods 6. The first ends of the two torsion arms 7 are respectively hinged to the torsion arm mounting seats 701 provided on both sides of the switch beam 1 and the second ends of the two vertical connecting rods 6, and the second ends of the two torsion arms 7 are respectively hinged to the first ends of the two horizontal connecting rods 8. The hook bodies of the two locking hooks 9 are hinged to the locking seats 901 provided on both sides of the switch beam 1, and the connecting ends of the two locking hooks 9 are respectively hinged to the second ends of the two horizontal connecting rods 8. The locking hooks of the two locking hooks 9 extend out of the two locking seats 901 and are respectively parallel to the two locking seats 901. The two locking hooks 9 are used to lock the tip rail end of the guide rail 2 after the guide rail 2 is switched to any position of the locking hook 9.

[0041] Among them, the switch beam 1 is a beam body in the suspension single-track switch for supporting the switch and vehicle switching. The switch beam 1 is a beam body with a lower opening. The main body of the switch beam 1 is formed by connecting a single-track beam and a double-track beam. The movable rail 3 is vertically arranged in the single-track beam of the switch beam 1, and the first end of the movable rail 3 is movably connected to the intersection of the double-track beam through a rotating shaft. The guide rail 2 is vertically arranged in the single-track beam of the switch beam 1. The cross-section of the guide rail 2 is an isosceles triangle. One end of the short side of the guide rail 2 is movably connected to the second end of the movable rail 3. After the tip rail end of the guide rail 2 is switched in place, it avoids close contact with the corresponding straight or curved beam body of the switch beam 1. Mounting seats are reserved on the switch beam 1. According to different structures and positions of each component, the components are fixedly connected to the switch beam 1 through mounting bases at the corresponding mounting seat positions. The suspension single-track switch guide rail 2 locking device provided by the embodiment of the present invention is entirely located above the tip rail end of the guide rail 2, so as to realize the locking and unlocking of the tip rail end of the guide rail 2.

[0042] Among them, the power push rod 4 is the power source of the locking device for the suspended single-track turnout guide rail 2. The power push rod 4 can be an electric push rod or a hydraulic cylinder linear drive unit, and the power push rod 4 makes a linear reciprocating motion. The power push rod 4 is hinged to the push rod swing arm 501. The power push rod 4 can be directly fixedly installed on the turnout beam 1, or can be fixedly installed on the turnout beam 1 through the crossbeam assembly 401 and the power push rod base 402. Specifically, the locking device for the suspended single-track turnout guide rail 2 further includes a crossbeam assembly 401 and a power push rod base 402. The crossbeam assembly 401 is fixedly installed on the turnout beam 1, the power push rod base 402 is fixedly installed on the crossbeam assembly 401, and the power push rod 4 is connected to the power push rod base 402 through a pin shaft.

[0043] In addition, the locking device for the suspended single-track turnout guide rail 2 further includes a controller 12, and the controller 12 is used to control the power push rod 4 to make a linear reciprocating motion according to the received suspended single-track turnout switching signal. The controller 12 can be separately arranged outside the power push rod 4 and control the movement of the power push rod 4 through electrical connection, or can be integrated inside the power push rod 4 to save the space of the device. The controller 12 can receive the suspended single-track turnout switching control signal in a wired manner, or can receive the suspended single-track turnout switching control signal through an integrated communication module in a wireless communication manner such as WIFI, Bluetooth, 4G, 5G signals, etc. The controller 12 can also determine whether the power push rod 4 is pushed out or retracted in place by obtaining the movement duration of the power push rod 4, obtaining the thrust value of the power push rod 4, etc. When the controller 12 receives the switching signals of the movable rail 3 and the guide rail 2, it synchronously controls the movement of the power push rod 4 to achieve unlocking of the guide rail 2 before the switching of the movable rail 3 and the guide rail 2, and locking of the guide rail 2 after the switching of the movable rail 3 and the guide rail 2 is in place.

[0044] Among them, both ends of the driving rotating shaft 5 pass through two bearing seats 503 respectively. The driving rotating shaft 5 and the two bearing seats 503 can be connected by clearance fit, or can be connected by means of a bearing fastening sleeve. The bearing seats 503 are symmetrically installed on both sides of the axial center position of the turnout beam 1, and the driving rotating shaft 5 can rotate in the two bearing seats 503. The push rod swing arm 501 and the two lifting arms 502 on the driving rotating shaft 5 can be integrally formed with the driving rotating shaft 5, or can be fastened to the driving rotating shaft 5 by means of threaded connection, etc. The embodiments of the present invention do not make specific limitations on this.

[0045] Among them, the vertical connecting rod 6 is a device connecting the lifting arms 502 at both ends of the driving rotating shaft 5 and the first end of the torsion arm 7. The vertical connecting rod 6 can be a rod-shaped structure, or can be a component structure of a threaded sleeve and a threaded rod. In a possible implementation manner, such as Figure 3As shown in the figure, the two vertical connecting rods 6 include a vertical rod body 601, a vertical rod spherical plain bearing 602, a vertical rod locking nut 603 and a vertical rod locking washer 604; the vertical rod body 601 is sleeved on the vertical rod spherical plain bearing 602 by means of threaded connection, the vertical rod locking nut 603 is arranged at the first end of the vertical rod spherical plain bearing 602, and the vertical rod locking washer 604 is arranged at the second end of the vertical rod spherical plain bearing 602. It should be noted that the inner ring of the vertical rod spherical plain bearing 602 can rotate around the vertical rod body 601, so as to release the torsional freedom degree during the operation of the push rod swing arm 501. After the vertical rod spherical plain bearing 602 is tightened and installed in place on the vertical rod body 601, the installation position of the vertical rod spherical plain bearing 602 can be locked by twisting and tightening the vertical rod locking nut 603, and then the ear of the vertical rod locking washer 604 can be bent to lock the vertical rod locking nut 603 to meet the requirement of preventing rotation.

[0046] Among them, the horizontal connecting rod 8 is a device for connecting the second end of the torsion arm 7 and the connecting end of the locking hook 9. The horizontal connecting rod 8 can be a rod-shaped structure or a component structure of a threaded sleeve and a threaded rod. In a possible implementation manner, as Figure 4 shown in the figure, the two horizontal connecting rods 8 include a horizontal rod body 801, a horizontal rod spherical plain bearing 802, a horizontal rod locking nut 803 and a horizontal rod locking washer 804; the horizontal rod body 801 is sleeved on the horizontal rod spherical plain bearing 802 by means of threaded connection, the horizontal rod locking nut 803 is arranged at the first end of the horizontal rod spherical plain bearing 802, and the horizontal rod locking washer 804 is arranged at the second end of the horizontal rod spherical plain bearing 802. It should be noted that the inner ring of the horizontal rod spherical plain bearing 802 can rotate around the horizontal rod body 801, so as to release the torsional freedom degree during the operation of the push rod swing arm 501. After the horizontal rod spherical plain bearing 802 is tightened and installed in place on the horizontal rod body 801, the installation position of the horizontal rod spherical plain bearing 802 can be locked by twisting and tightening the horizontal rod locking nut 803, and then the ear of the horizontal rod locking washer 804 can be bent to lock the horizontal rod locking nut 803 to meet the requirement of preventing rotation.

[0047] Among them, the locking hook 9 is a device for locking the tip rail end of the guide rail 2. The hook body of the locking hook 9 is perpendicular to the guide rail 2, and the hook body of the locking hook 9 is hinged to the locking seats 901 arranged on both sides of the switch beam 1. Thus, when the connecting end of the locking hook 9 is pulled by the horizontal connecting rod 8, the locking hook 9 can rotate around the locking seat 901, so as to realize the rotation of the locking hook of the locking hook 9, and further realize the locking and unlocking of the guide rail 2.

[0048] It should be noted that the connecting parts of the lifting arm 502, the torsion arm 7, and the locking hook 9 are all connected to the respective tie rods by means of hinges. If a direct connection method is adopted, after the device runs for a period of time, the connection parts will wear due to large frictional resistance, and there will be a risk of device instability after a long running time. Therefore, in a certain implementation method, the connecting parts of the lifting arms 502 at both ends of the driving rotating shaft 5, the two torsion arms 7, and the two locking hooks 9 are all hinged through lubricating sleeves, thereby effectively reducing the frictional resistance during the operation of the device and improving the stability of the device. Specifically, among the lifting arm 502, the torsion arm 7, and the locking hook 9, the lubricating sleeve is connected to the rotating layout by interference fit. The material of the lubricating sleeve is not limited to metal or non-metal parts such as high-strength brass, composite materials, polytetrafluoroethylene, and nylon. The lubricating sleeve is detachable and can be replaced and adjusted according to the wear amount.

[0049] In addition, in order to further improve the locking effect on the guide rail 2, locking grooves 11 can be respectively arranged below the guide rail 2 at two positions after reaching the position. The lower end of the guide rail 2 is limited by the locking grooves 11 to cooperate with the locking hook 9 to lock the switch rail end and the lower part of the guide rail 2 synchronously. Specifically, the suspension single-rail turnout guide rail 2 locking device further includes two locking grooves 11, and the two locking grooves 11 are respectively arranged above the bottom position of the turnout beam 1 when the guide rail 2 is switched in place. The locking grooves 11 are connected to the guide rail 2 through grooves.

[0050] In addition, in order to improve the locking efficiency of the suspension single-rail turnout guide rail 2 locking device and reduce the operation safety risk of the device, two detection mechanisms 10 can be respectively arranged beside the two locking hooks 9. Figure 5 is a three-dimensional view of the detection mechanism 10 in a suspension single-rail turnout guide rail 2 locking device provided by an embodiment of the present invention. See Figure 5 . Specifically, the two detection mechanisms 10 include a travel switch 1001, a switch bracket 1002, and a spherical support 1003. The travel switch 1001 and the spherical support 1003 are both arranged on the switch bracket 1002. The travel switch 1001 and the spherical support 1003 are connected by an installation guide post. The two switch brackets 1002 are respectively fixedly arranged on both sides of the turnout beam 1.

[0051] It should be noted that after the guide rail 2 is switched to the in-place position, it is in close contact with the web of the switch beam 1. The locking hook 9 rotates to buckle and press the guide rail 2. At this time, the spherical support 1003 contacts the guide rail 2, and the installation guide post between the spherical support 1003 and the travel switch 1001 can be compressed in the switch bracket 1002, thereby triggering the action of the travel switch 1001, obtaining the signal that the guide rail 2 is switched to the in-place position, and the travel switch 1001 then transmits the signal that the guide rail 2 is switched to the in-place position to the controller 12, and the controller 12 performs the next operation according to the preset conditions. When the locking hook 9 is unlocked, the guide rail 2 has a height lifting requirement at the original position. During the lifting process, the movable rail 3 drives the ball in the spherical support 1003 to rotate, which can reduce the sliding friction between the detection switch ball head and the guide rail 2 assembly.

[0052] When the embodiment of the present invention is working, the controller 12 obtains a control signal and controls the power push rod 4 to perform a linear reciprocating motion according to the control signal. When the power push rod 4 performs a linear reciprocating motion, it synchronously pushes the push rod swing arm 501 on the drive rotating shaft 5 and drives the drive rotating shaft 5 to start rotating. At this time, the lifting arm 502 on the drive rotating shaft 5 also rotates synchronously. The rotation of the lifting arm 502 drives the vertical pull rod to move up and down vertically, thereby pulling the torsion arm 7 to rotate. The rotating torsion arm 7 drives the horizontal connecting rod 8 to perform a linear reciprocating motion in the horizontal direction, thereby driving the locking hook 9 to rotate around the hinge at the locking seat 901, and further causing the locking hook of the locking hook 9 to rotate. When the locking hook rotates into the locking seat 901, the movable rail 3 is unlocked. When the locking hook rotates perpendicular to the locking seat 901, the locking of the guide rail 2 can be achieved, as Figure 6 shown.

[0053] In an embodiment of the present invention, the hanging single-rail switch guide rail locking device includes a switch beam and a guide rail, and further includes a power push rod, a driving rotating shaft, two vertical connecting rods, two torsion arms, two horizontal connecting rods, and two locking hooks; a push rod swing arm is provided at the central position of the driving rotating shaft, and lifting arms are respectively provided at both ends of the driving rotating shaft. The driving rotating shaft is installed on the top of the switch beam through two bearing seats; the power push rod is installed on the top of the switch beam, and the end of the push rod of the power push rod is hinged to the push rod swing arm. The lifting arms at both ends of the driving rotating shaft are respectively hinged to the first ends of the two vertical connecting rods; the first ends of the two torsion arms are respectively hinged to the torsion arm mounting seats provided on both sides of the switch beam and the second ends of the two vertical connecting rods, and the second ends of the two torsion arms are respectively hinged to the first ends of the two horizontal connecting rods; the hook bodies of the two locking hooks are hinged to the locking seats provided on both sides of the switch beam, and the connecting ends of the two locking hooks are respectively hinged to the second ends of the two horizontal connecting rods. The locking hooks of the two locking hooks extend out of the two locking seats and are respectively parallel to the two locking seats. The two locking hooks are used to lock the tip rail end of the guide rail after the guide rail is switched to any locking hook position. That is, in the embodiment of the present invention, locking hooks are respectively provided on both sides of the switch beam. When the guide rail is switched with the movable rail, the power push rod moves linearly synchronously, pushing the driving rotating shaft to rotate. The driving rotating shaft drives the vertical connecting rods, torsion arms, and horizontal connecting rods to move. After the guide rail is switched in place, the horizontal connecting rod pulls the locking hook to rotate, realizing the locking of the tip rail end of the guide rail, thereby ensuring the fitting and position locking of the tip rail end of the guide rail and the web of the switch beam, ensuring vehicle passage, and improving driving safety.

[0054] In addition, in a possible implementation manner, the hanging single-rail switch guide rail locking device provided in the embodiment of the present invention can be applied to a hanging single-rail switch. Specifically, the hanging single-rail switch includes a movable rail lifting device, a movable rail switching device, a compensating rail locking device, and the hanging single-rail switch guide rail locking device provided in the embodiment of the present invention; the movable rail lifting device and the movable rail switching device are connected to the movable rail, and the movable rail lifting device and the movable rail switching device are used to lift and switch the movable rail; the compensating rail locking device and the movable rail lifting device share a set of power sources and are used to lock the compensating rail after the movable rail is lifted in place; the guide rail is connected to the end of the rotation center of the movable rail. After the hanging single-rail switch guide rail locking device drives the guide rail to be switched in place by the movable rail, it locks the tip rail end of the guide rail.

[0055] In the above turnout, the movable rail lifting device and the movable rail switching device can lift and switch the movable rail in the turnout. The compensating rail locking device can lock and unlock the compensating rail during the lifting and switching of the movable rail, and the guide rail locking device can lock and unlock the guide rail during the lifting and switching of the movable rail, thereby realizing the locking and unlocking of the compensating rail and the guide rail synchronously on the basis of the overall switching of the turnout.
