Description

Technical Field

[0001] The present invention relates to the technical field of rail lines, and particularly relates to an elastic strip disassembling and assembling device. Background Art

[0002] A turnout is one of the important components of a railway track. Due to its large number, complex structure, short service life, limited train speed, low train operation safety, and high maintenance investment, it is known as one of the three weak links together with curves and joints. As an important component of the turnout, the slide plate supports the switch rail and presses the stock rail within the entire length range of the switch rail.

[0003] In the past, the slide plate used elastic strips and pins to elastically press the inner side of the stock rail. With the rapid development of China's railway, at present, Schweiger elastic strips are used to press and hold the inner cavity of the slide plate in the turnout switching parts of heavy-haul railways and high-speed railways on the bottom of the stock rail. In the prior art, the disassembly and assembly of elastic strips require a lot of manual work and there is no good disassembly and assembly tool. There are the following problems in manually disassembling and assembling the elastic strips of the turnout: (1) During the disassembly process, the extruded and bounced elastic strips are easy to fly out and hurt people, resulting in labor safety problems; (2) When prying up the elastic strip, the height between the tail end of the elastic strip and the slide plate is limited, and it is not easy to hammer the tail during hammering, and it is easy to hammer and damage the slide table; (3) Manually disassembling and assembling the elastic strips is time-consuming and laborious, with low efficiency and difficult to guarantee the quality.

[0029] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings. This is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] Such as Figure 1 AndFigure 2 As shown in the figure, the elastic strip disassembly and assembly device of the present invention includes a frame 1, a disassembly and assembly mechanism 2, and a lifting mechanism 3.

[0032] As Figures 4 to 6 shown, the disassembly and assembly mechanism 2 includes two loosening members 21, two driving arms 22, and a connecting component. The two loosening members 21 are both used for clamping the elastic strip. The two driving arms 22 are used to drive the two loosening members 21 to act, so as to grasp the elastic strip. One end of the two driving arms 22 is rotatably connected, and the other end of each driving arm 22 is respectively rotatably connected to the upper end of a loosening member 21. The connecting component is connected between the two loosening members 21 to make the two loosening members 21 move synchronously.

[0033] A clamping portion 211 is provided at the lower part of each loosening member 21, and a clamping groove adapted to the end profile of the elastic strip is provided on the clamping portion 211. When the elastic strip is grasped by the loosening member 21, the end of the elastic strip is clamped in the clamping groove, so that the clamping portion 211 clamps reliably and the elastic strip is not easily disengaged from the clamping portion 211.

[0034] Define the extending direction of the rail as the left-right direction. When the two driving arms 22 rotate relative to each other, they drive the two loosening members 21 to move synchronously in the up-down direction and simultaneously move towards or away from each other in the left-right direction, so as to realize grasping or releasing the elastic strip.

[0035] When the elastic strip is grasped by the clamping portion 211, due to the elasticity of the elastic strip, it will undergo a certain elastic deformation, such as warping, when subjected to the force of the clamping portion 211. In this embodiment, the movement trajectory of the clamping portion 211 when grasping the elastic strip is an arc, which is exactly the same as the deformation trajectory of the elastic strip. The same is true when the clamping portion 211 releases the elastic strip, and the movement trajectory of the clamping portion 211 is consistent with the trajectory of the elastic strip recovering its elastic deformation. In this way, it can prevent the elastic strip from flying out during disassembly and assembly, and improve the safety performance during disassembly and assembly of the elastic strip.

[0036] The disassembly and assembly mechanism 2 further includes a first driving mechanism, and the first driving mechanism is used to drive the relative rotation between the two driving arms 22. The first driving mechanism includes a first fixing portion 231 and a first moving portion 232 slidably arranged on the first fixing portion 231 in the left-right direction. The first fixing portion 231 is rotatably connected to one driving arm 22, and the first moving portion 232 is rotatably connected to the other driving arm 22. In this way, a crank-slider mechanism is formed among the two driving arms 22, the first fixing portion 231, and the first moving portion 232. When the first moving portion 232 of the first driving mechanism slides relative to the first fixing portion 231, the two driving arms 22 can be driven to rotate relative to each other.

[0037] In this embodiment, the first driving mechanism uses an oil cylinder, the first fixing part 231 is the cylinder block of the oil cylinder, and the first moving part 232 is the piston rod of the oil cylinder.

[0038] In this embodiment, each driving arm 22 includes an upper arm 221, a middle arm 222, and a lower arm 223 arranged in sequence from top to bottom. The upper arm 221 extends obliquely upward from the upper part of the middle arm 222 and in the direction of the other driving arm 22, and the lower arm 223 extends obliquely downward from the lower part of the middle arm 222 and in the direction of the other driving arm 22. The ends of the two upper arms 221 far from the middle arm 222 are rotatably connected, and the end of each lower arm 223 far from the middle arm 222 is rotatably connected to the upper end of the loosening member 21. The first driving mechanism is arranged between the two middle arms 222, the first fixing part 231 is rotatably connected to one middle arm 222, and the first moving part 232 is rotatably connected to the other middle arm 222.

[0039] The connecting assembly includes a connecting seat 24 and a connecting rod 25. One end of the connecting seat 24 is rotatably connected to one loosening member 21, and the other end of the connecting seat 24 is rotatably connected to the other loosening member 21. One end of the connecting rod 25 is rotatably connected to one loosening member 21, and the other end of the connecting rod 25 is rotatably connected to the other loosening member 21. The connecting seat 24 and the connecting rod 25 are arranged in a crosswise manner, that is, on one loosening member 21, the connection position of the connecting seat 24 and this loosening member 21 is above the connection position of the connecting rod 25 and this loosening member 21, while on the other loosening member 21, the connection position of the connecting seat 24 and this loosening member 21 is below the connection position of the connecting rod 25 and this loosening member 21.

[0040] In this embodiment, the connecting seat 24 is horizontally arranged in the left - right direction, and U - shaped slots are provided on both the left and right sides of the connecting seat 24. The two loosening members 21 are respectively rotatably arranged in these slots, which makes the structure of the disassembly and assembly mechanism compact. The connecting rod 25 is inclined relative to the connecting seat 24.

[0041] The disassembly and assembly mechanism 2 further includes a limiting member 26 for limiting the left - right movement of the two loosening members 21. A limiting groove 261 extending in the left - right direction and cooperating with the loosening member 21 is provided on the limiting member 26. The two loosening members 21 are both inserted into the limiting groove 261 and can move in the up - down direction and the extending direction of the limiting groove 261.

[0042] The two loosening members 21 can also be arranged to be slidable synchronously in the front - back direction, so as to realize the installation of the elastic pressing strip. The disassembly and assembly mechanism 2 further includes a connecting plate 27 and a second driving mechanism. The connecting plate 27 is used to connect the lifting mechanism 3, and the second driving mechanism is used to drive the two loosening members 21 to move synchronously in the front - back direction. The second driving mechanism is arranged on the connecting plate 27.

[0043] The second driving mechanism includes a second fixed part 281 and a second movable part 282 slidably arranged on the second fixed part 281 in the front-back direction. The second fixed part 281 is fixedly arranged on the connecting plate 27, and the limiting part 26 is fixedly arranged on the second movable part 282.

[0044] In this embodiment, the second driving mechanism also adopts an oil cylinder. The second fixed part 281 is the cylinder body of the oil cylinder, and the second movable part 282 is the piston rod of the oil cylinder.

[0045] The disassembly and assembly mechanism 2 further includes a support seat 291. The connecting seat 24 is slidably arranged on the support seat 291 in the front-back direction, and the support seat 291 is slidably arranged on the connecting plate 27 in the up-down direction.

[0046] Specifically, a chute 271 extending in the up-down direction is arranged on the connecting plate 27. A bearing 292 is arranged on the support seat 291. The bearing 292 is located in the chute 271 and can slide along the extending direction of the chute 271.

[0047] When the second movable part 282 slides relative to the second fixed part 281 in the front-back direction, it drives the limiting part 26, the two loosening parts 21, the two driving arms 22 and the connecting assembly to slide synchronously in the front-back direction as a whole, so that the connecting seat 24 slides relative to the support seat 291 in the front-back direction. When the first movable part 232 slides relative to the first fixed part 231 in the left-right direction, it drives the two loosening parts 21 and the connecting assembly to move in the up-down direction as a whole through the two driving arms 22. At the same time, the two loosening parts 21 move towards or away from each other in the left-right direction, driving the support seat 291 to slide relative to the connecting plate 27 in the up-down direction.

[0048] The disassembly and assembly mechanism 2 is integrally slidably arranged on the frame 1. The lifting mechanism 3 is arranged on the frame 1 and is connected or cooperated with the disassembly and assembly mechanism 2 to drive the disassembly and assembly mechanism 2 to slide in the up-down direction on the frame 1 as a whole.

[0049] As Figure 1 and Figure 2 shown, the lifting mechanism 3 includes a lead screw 31, a slider 32 and a motor 33. The motor 33 is fixedly arranged on the frame 1. The lead screw 31 extends in the up-down direction. The lead screw 31 is connected to the motor shaft of the motor 33, so that the lead screw 31 is driven by the motor 33 to rotate relative to the frame 1 around its own axis. The slider 32 is connected to the lead screw 31 through a threaded fit. The disassembly and assembly mechanism 2 is arranged on the slider 32. In this embodiment, the connecting plate 27 is fixedly connected to the slider 32.

[0050] When the motor 33 rotates, it drives the lead screw 31 to rotate, so that the slider 32 slides along the extending direction of the lead screw 31, thereby driving the disassembly and assembly mechanism 2 to slide synchronously as a whole.

[0051] As Figure 1And Figure 2 As shown in Figure 2 , the disassembly and assembly device further includes a traveling frame assembly. The frame 1 is movably arranged on the traveling frame assembly in the front - rear direction, and the traveling frame assembly is movably arranged on the rail in the left - right direction, i.e., the extending direction of the rail.

[0052] Specifically, tracks 411 extending in the front - rear direction are arranged on the traveling frame assembly, and the tracks 411 are respectively arranged on the left and right sides of the traveling frame assembly. Correspondingly, at least one set of first wheel sets 11 are respectively arranged on the left and right sides of the bottom of the frame 1. Each set of first wheel sets 11 on each side is movably arranged on the corresponding track 411 along the extending direction of the corresponding track 411.

[0053] As Figure 3 shown in Figure 3 , the first wheel set 11 has a first tread surface 111 that is in rolling contact with the track 411. At least one side surface of the outer side and the inner side of the first tread surface 111 is provided with a first retaining edge 112. The first retaining edge 112 is used to clamp the side surface of the track 411. By setting the first retaining edge 112, the frame 1 and the components arranged thereon are tightly clamped on the track 411, and it is not easy to have the problem of disengaging from the track 411. In this embodiment, the first retaining edges 112 are respectively arranged on the inner side and the outer side of the first tread surface 111.

[0054] In this embodiment, the tracks 411 on the left and right sides of the traveling frame assembly are both of double - track structure.

[0055] As Figure 7 and Figure 8 shown in Figure 7 and Figure 8 , at least one set of second wheel sets 43 are respectively arranged on each side of the left and right sides of the traveling frame assembly. The second wheel set 43 has a second tread surface 431 that is in rolling contact with the rail. At least one side surface of the outer side and the inner side of the second tread surface 431 is provided with a second retaining edge 432. The second retaining edge 432 is used to clamp the side surface of the rail. By setting the second retaining edge 432, the disassembly and assembly device is tightly clamped on the rail, and it is not easy to have the problem of disengaging from the rail. In this embodiment, the second retaining edges 432 are respectively arranged on the inner side of the second tread surface 431.

[0056] As Figure 7 and Figure 8 shown in Figure 7 and Figure 8 , the traveling frame assembly includes a first traveling frame 41 and a second traveling frame 42. One end of the first traveling frame 41 and the second traveling frame 42 is rotatably connected. The frame 1 is movably arranged on the first traveling frame 41 in the front - rear direction, that is, the track 411 is arranged on the first traveling frame 41. The second wheel sets 43 are respectively arranged on the left and right sides of the first traveling frame 41 and the left and right sides of the second traveling frame 42.

[0057] The left and right sides of the second running frame 42 are also provided with running wheels 44, respectively. The running wheels 44 are located on the second running frame 42 at one end close to the first running frame 41. The running frame assembly has a first state and a second state. When the elastic pressure strip is disassembled, the running frame assembly is in the first state. At this time, the second running frame 42 is away from the first running frame 41, the running wheels 44 are located above the second running frame 42, and the second wheel group 43 is at the lowest position, which is in rolling contact with the rail. Figure 1 , Figure 2 and Figure 7 When the disassembly and assembly equipment is carried, the running frame assembly is in the second state, at which time the second running frame 42 is close to the first running frame 41, the running wheel 44 is located below the second running frame 42, and the lower end surface of the running wheel 44 is located below the lower end surface of the second wheel assembly 43, as shown in FIG. Figure 8 In this state, the entire disassembly and assembly equipment can be raised to the side away from the running wheel 44, and the disassembly and assembly equipment can be quickly taken up and down the road, making the disassembly and assembly equipment easy to carry.

[0058] The method of disassembling the elastic pressure strip by the disassembly and assembly equipment is as follows:

[0059] (1) By moving the second wheel set 43 along the rail, the first wheel set 11 moves along the track 411, so that the disassembly and assembly equipment moves to the position where the elastic pressure strip is installed on the rail;

[0060] (2) The disassembly and assembly mechanism 2 is moved downward as a whole by the lifting mechanism 3 until the clamping parts 211 of the two loose parts 21 are close to the elastic pressure strip;

[0061] (3) The first driving mechanism is started, and the first movable portion 232 moves away from the first fixed portion 231, so that the two driving arms 22 rotate relative to each other, driving the two loose parts 21 to move in the up-down direction and move toward each other, thereby grabbing the elastic pressure strip at the corresponding position through the clamping portion 211;

[0062] (4) After the clamping portion 211 grabs the elastic pressure strip, the disassembly and assembly mechanism 2 is moved upward by a certain distance as a whole through the lifting mechanism 3;

[0063] (5) The first driving mechanism is reset, and the first movable portion 232 moves toward the first fixed portion 231, so that the two driving arms 22 rotate relative to each other, driving the two loose parts 21 to move in the up and down directions and move away from each other, thereby loosening the elastic pressure strip and allowing the end of the elastic pressure strip to escape from the clamping portion 211, thereby completing the disassembly operation of the elastic pressure strip.

[0064] The method of installing the elastic strip by means of the disassembly and assembly equipment is as follows:

[0065] (1) Manually clamp the elastic strip at a certain angle and insert it from above the opening of the slide bed;

[0066] (2) by moving the second wheel set 43 along the rail, the first wheel set 11 moves along the track 411, so that the disassembly and assembly equipment moves to the position where the elastic pressure strip is installed on the rail;

[0067] (3) The disassembly and assembly mechanism 2 is moved downward as a whole by the lifting mechanism 3 until the clamping parts 211 of the two loose parts 21 are close to the elastic pressure strip;

[0068] (4) The first driving mechanism is started, and the first movable portion 232 moves away from the first fixed portion 231, so that the two driving arms 22 rotate relative to each other, driving the two loose parts 21 to move in the up-down direction and move toward each other, thereby grabbing the elastic pressure strip at the corresponding position through the clamping portion 211;

[0069] (5) After the clamping portion 211 grabs the elastic strip, the second driving mechanism is activated, and the second movable portion 282 slides forward relative to the second fixed portion 281, driving the two loose parts 21 and the elastic strip clamped in the clamping portion 211 to move forward until the elastic strip moves to the set position;

[0070] (6) The disassembly and assembly mechanism 2 is moved downward as a whole by the lifting mechanism 3, thereby pressing down the elastic pressure strip to make it stuck at the set position;

[0071] (7) The first driving mechanism is reset, and the first movable portion 232 moves toward the first fixed portion 231, causing the two driving arms 22 to rotate relative to each other, driving the two loose parts 21 to move in the up and down directions and move away from each other, thereby loosening the elastic pressure strip and allowing the end of the elastic pressure strip to disengage from the clamping portion 211, thereby completing the installation operation of the elastic pressure strip.

[0072] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention.
