Description

Technical Field

[0001] The present invention relates to the technical field of air rail transportation, in particular to a lifting device and a turnout. Background Art

[0002] A turnout is a connecting device that allows rolling stock to transfer from one track to another. It's also a weak link in track construction and is typically installed in large numbers at stations and marshalling yards. Turnouts maximize the capacity of a line. Even on a single-track railway, laying a turnout and constructing a fork line longer than the length of the train allows trains to run in opposite directions. Turnouts play a vital role on railway lines.

[0003] However, in the prior art, the main line and branch line of the turnout are separated to form a gap. When the vehicle switches between the main line and the branch line, it is necessary to replace the curved turnout body with the straight turnout body at the gap. However, the replacement time is long and the work efficiency is low. Summary of the Invention

[0004] The present invention provides a lifting device and a turnout, which solve or partially solve the technical problems in the prior art of long replacement time and low working efficiency when vehicles switch between a main line and a straight line.

[0005] In order to solve the above technical problems, the present invention provides a lifting device comprising at least one lifting assembly; the lifting assembly comprises: two columns, which are arranged on the switch; two support seats, which are slidably arranged on the two columns and switch between a first position and a second position; a lever seat, which is arranged on the switch, and the lever seat is arranged between the two support seats; a lever, the middle part of which is rotatably arranged on the lever seat, and the two sides of the middle part of the lever are slidably connected to the two support seats to convert the rotational motion of the lever into linear motion of the support seat, wherein, when one of the two support seats is in the first position, the other of the two support seats is in the second position.

[0006] Furthermore, first sliding grooves are provided on both sides of the middle portion of the lever along the length direction of the lever, and sliding blocks are provided on the two support seats, and the sliding blocks are arranged in the first sliding grooves.

[0007] Furthermore, a rotary pulley is rotatably provided on the support seat, and the slider is provided on the rotary pulley.

[0008] Furthermore, the lifting device also includes: a driving assembly, a fixed end of which is hinged to the switch, and an action end of the driving assembly is hinged to the lever and is arranged between the lever seat and one of the two support seats.

[0009] Furthermore, the driving assembly includes: a mounting seat fixed on the turnout; a driver hinged to the mounting seat, an actuating end of the driver hinged to the lever, and disposed between the lever seat and one of the two support seats.

[0010] Furthermore, a fixed pulley is provided at the end of the column away from the turnout; the lifting device also includes a connecting rope, one end of which is connected to one of the two support seats, and the other end is wound around the two fixed pulleys and connected to the other of the two support seats.

[0011] Furthermore, a second sliding groove is provided on the support seat, a sliding rail is provided on the column, and the sliding rail is arranged in the second sliding groove.

[0012] Furthermore, a buffer seat is provided on the support seat.

[0013] Furthermore, there are two lifting assemblies, and the two lifting assemblies are arranged at intervals.

[0014] Based on the same inventive concept, the present application also provides a turnout, including the lifting device.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0016] In the existing technology, when a vehicle enters the main line from a branch line or enters the branch line from the main line, it is necessary to move the straight switch body out of the neutral gear and then move the curved switch body into the neutral gear. When the vehicle is traveling on the main line, it is necessary to move the curved switch body out of the neutral gear and then move the straight switch body into the neutral gear, resulting in a long replacement time between the straight switch body and the curved switch body and low work efficiency.

[0017] Since the two columns are arranged on the switch, the two support seats are respectively slidably arranged on the two columns and switch between the first position and the second position, the lever seat is arranged on the switch, the lever seat is arranged between the two support seats, the middle part of the lever is rotatably arranged on the lever seat, and the two sides of the middle part of the lever are respectively slidably connected to the two support seats to convert the rotational motion of the lever into the linear motion of the support seat. When one of the two support seats is in the first position, the other of the two support seats is in the second position. Therefore, the straight turnout beam and the curved turnout beam are respectively installed on the two support seats. On the support seat, when the straight turnout beam and the curved turnout beam need to be replaced, the lever is rotated on the lever seat to convert the rotational motion of the lever into the linear motion of the support seat, so that the two support seats slide on the corresponding columns respectively, and one of the two support seats rises and the other support seat falls, that is, the rising and falling of the two support seats are carried out simultaneously, ensuring the synchronization of the movements of the straight turnout beam and the curved turnout beam. In other words, when one of the straight turnout beam and the curved turnout beam falls to the working position, the other rises to the storage position, which facilitates operation, improves work efficiency and reduces replacement time.

[0022] See also Figure 1-3 , a lifting device provided by an embodiment of the present invention includes: at least one lifting component 2.

[0023] The lifting assembly 2 includes: a lever seat 2-1, a lever 2-2, two columns 2-3 and two support seats 2-4.

[0024] Two columns 2 - 3 are provided on the turnout 1 .

[0025] The two support seats 2-4 are slidably disposed on the two columns 2-3 respectively.

[0026] The lever seat 2-1 is arranged on the turnout 1, and the lever seat 2-1 is arranged between the two support seats 2-4.

[0027] The middle part of the lever 2-2 is rotatably arranged on the lever seat 2-1, and the two sides of the middle part of the lever 2-2 are slidably connected to the two support seats 2-4 to convert the rotational motion of the lever 2-2 into the linear motion of the support seat 2-4.

[0028] When one of the two support seats 2 - 4 is located at the first position, the other of the two support seats 2 - 4 is located at the second position.

[0029] The two columns 2-3 are arranged opposite to each other.

[0030] The two support seats 2-4 are arranged opposite to each other and between the two columns 2-3.

[0031] In the existing technology, when a vehicle enters the main line from a branch line or enters the branch line from the main line, it is necessary to move the straight switch body out of the neutral gear and then move the curved switch body into the neutral gear. When the vehicle is traveling on the main line, it is necessary to move the curved switch body out of the neutral gear and then move the straight switch body into the neutral gear, resulting in a long replacement time between the straight switch body and the curved switch body and low work efficiency.

[0032] Since the two columns 2-3 are provided on the switch 1, the two support seats 2-4 are respectively slidably provided on the two columns 2-3 and switch between the first position and the second position, the lever seat 2-1 is provided on the switch 1, the lever seat 2-1 is provided between the two support seats 2-4, the middle part of the lever 2-2 is rotatably provided on the lever seat 2-1, and the two sides of the middle part of the lever 2-2 are respectively slidably connected to the two support seats 2-4 to convert the rotational motion of the lever 2-2 into the linear motion of the support seat 2-4. When one of the two support seats 2-4 is located in the first position, the other of the two support seats 2-4 is located in the second position. Therefore, the straight turnout beam 4 and the curved turnout are connected. The beam 3 is respectively installed on the two support seats 2-4. When the straight turnout beam 4 and the curved turnout beam 3 are to be replaced, the lever 2-2 is rotated on the lever seat 2-1 to convert the rotational motion of the lever 2-2 into the linear motion of the support seat, so that the two support seats 2-4 slide on the corresponding columns respectively, and one of the two support seats 2-4 rises and the other falls, that is, the rising and falling of the two support seats 2-4 are carried out simultaneously, ensuring the synchronization of the movements of the straight turnout beam 4 and the curved turnout beam 3. That is, when one of the straight turnout beam 4 and the curved turnout beam 3 falls to the working position, the other rises to the storage position, which is convenient for operation, improves work efficiency and reduces replacement time.

[0033] In the prior art, due to the large mass of the curved and straight turnout bodies, it can be difficult to move or stop during replacement. In some embodiments, the two sides of the middle portion of the lever 2-2 are slidably connected to the two support seats 2-4, achieving gravity balance and low operating resistance. As long as the driving force is greater than the operating inertia force and the friction between the column and the support seat, the support seat can be moved.

[0034] In some embodiments, in order to convert the rotational motion of the lever 2-2 into the linear motion of the support seat 2-4, a first sliding groove is opened on both sides of the middle part of the lever 2-2 along the length direction of the lever 2-2, and a slider is provided on the two support seats 2-4, and the slider is arranged in the first sliding groove.

[0035] In this embodiment, when the lever 2-2 rotates, the slider slides in the first sliding groove to prevent the lever 2-2 from interfering with the lifting and lowering of the support seat 2-4.

[0036] In this embodiment, in order to facilitate the sliding of the slider in the first slide groove, a rotary pulley 5 is rotatably provided on the support seat 2-4, and the slider is provided on the rotary pulley 5. That is to say, when the slider slides in the first slide groove, the rotary pulley 5 drives the slider to rotate, reducing the friction of the slider in the first slide groove, so as to facilitate the lifting and lowering of the support seat 2-4.

[0037] In some embodiments, in order to realize the rotation of the lever 2-2 on the lever seat 2-1, the lifting device further includes a drive assembly 6. The fixed end of the drive assembly 6 is hinged to the switch 1, and the operating end of the drive assembly 6 is hinged to the lever 2-2 and is arranged between the lever seat 2-1 and one of the two support seats 2-4.

[0038] In this embodiment, when the straight turnout beam 4 and the curved turnout beam 3 are to be replaced, the drive assembly 6 is started, and the action end of the drive assembly 6 drives the lever 2-2 to rotate on the lever seat 2-1, so that the lever 2-2 drives the two support seats 2-4 to move on the two columns 2-3 respectively.

[0039] In this embodiment, the driving assembly 6 includes: a mounting seat 6-1 and a driver 6-2.

[0040] The mounting seat 6 - 1 is fixed on the turnout 1 .

[0041] The driver 6-2 is hinged to the mounting seat 6-1, and the action end of the driver 6-2 is hinged to the lever 2-2 and is arranged between the lever seat 2-1 and one of the two support seats 2-4. In this embodiment, the driver 6-2 can be an electric cylinder.

[0042] In this embodiment, when the straight turnout beam 4 and the curved turnout beam 3 are to be replaced, the driver 6-2 is started, and the action end of the driver 6-2 drives the lever 2-2 to rotate on the lever seat 2-1, so that the lever 2-2 drives the two support seats 2-4 to move on the two columns 2-3 respectively.

[0043] Of course, in other embodiments, the drive assembly 6 may also include a motor, with the fixed end of the motor disposed on the lever base 2-1 and the actuating end of the motor connected to the middle portion of the lever 2-2. When the motor is activated, the actuating end of the motor can also drive the lever 2-2 to rotate. However, compared to motors, electric cylinders offer higher precision, longer service life, faster speed, and lower maintenance costs. Therefore, preferably, the first actuator 6-2 of the first drive assembly 6 is an electric cylinder.

[0044] In the prior art, due to the large mass of the curved and straight turnout bodies, two sets of motors are required to drive the curved and straight turnout bodies respectively. Each set of motors is composed of multiple motors, resulting in high costs. However, the present application only requires a single driver to drive the lever 2-2 to rotate, saving costs.

[0045] In some embodiments, to ensure safety, a fixed pulley 7 is provided at the end of the column 2-3 facing away from the turnout. The lifting device further comprises a connecting rope 8, one end of which is connected to one of the two support seats 2-4, and the other end of which is wound around the two fixed pulleys 7 and connected to the other of the two support seats 2-4. The fixed pulleys 7 ensure smooth lifting of the two support seats 2-4. In other words, when the lever 2-2 fails, the connecting rope 8 holds the two support seats 2-4 in place, preventing them from falling simultaneously and ensuring the safety of the equipment.

[0046] At the same time, since the two ends of the connecting rope 8 are respectively connected to the two support seats 2-4, the gravity at both ends of the lever 2-2 is further balanced, the running resistance is small, and the support seat can be moved as long as the driving force is greater than the running inertia force and the friction between the column and the support seat.

[0047] In some embodiments, to reduce driving force, a second chute is provided on the support base 2-4, and a slide rail 9 is provided on the column 2-3. The slide rail 9 is disposed within the second chute. When the support base 2-4 is raised or lowered, the second chute slides on the slide rail 9, thereby improving motion accuracy and being able to withstand loads in all directions. In this embodiment, the slide rail 9 is a linear guide rail and is disposed in the vertical direction, thereby improving motion accuracy.

[0048] See also Figure 4In some embodiments, to facilitate installation of the straight turnout beam 4 and the curved turnout beam 3, a buffer seat 10 is provided on the support seat 2-4. The buffer seat 10 supports the straight turnout beam 4 and the curved turnout beam 3. The buffer seat 10 can be selected to an appropriate size as needed to adjust the installation dimensions of the straight turnout beam 4 and the curved turnout beam 3 and reduce installation difficulty. In this embodiment, the buffer seat 10 can be made of rubber.

[0049] In this embodiment, in order to ensure the stability of supporting the straight turnout beam 4 and the curved turnout beam 3, the cross-sectional shape of the buffer seat 10 can be an "I" shape.

[0050] In some embodiments, to ensure the stability of the movement of the straight turnout beam 4 and the curved turnout beam 3, two lifting assemblies 2 are provided, and the two lifting assemblies 2 are spaced apart. In this embodiment, the ends of the straight turnout beam 4 and the curved turnout beam 3 are respectively mounted on two lifting devices 2, ensuring that the ends of the straight turnout beam 4 and the curved turnout beam 3 move in unison.
