Description

Technical Field

[0001] This invention relates to the field of vehicle tooling technology, and more specifically, to a bogie transfer tooling and transfer method. Background Technology

[0002] Currently, the bogie mounting process is a crucial step in the assembly of rail vehicles. The usual practice is to first move the bogie to the vicinity of the track beam, and then use cranes or other lifting equipment to hoist the bogie onto the track beam.

[0003] However, during the bogie's upper rail operation, when the bogie is hoisted to the rail beam and lowered onto the rail beam, it is not only easy to cause damage to the wheel system on the bogie, but the bogie is also prone to shaking, which makes alignment complicated and affects the efficiency of operation. Summary of the Invention

[0006] Optionally, the beam body is provided with a first pin hole, and the moving trolley is provided with a second pin hole; the locking device includes a pin shaft, which passes through the first pin hole and the second pin hole to lock the beam body and the moving trolley.

[0007] Optionally, when the cross-sectional shape of the pin, the first pin hole, and the second pin hole is circular, the moving trolley is locked or unlocked to the beam by at least two of the pins.

[0008] Optionally, the locking device further includes a hand-held component disposed at one end of the pin along its length.

[0009] Optionally, the mobile trolley includes a support plate, a second traveling device, and a reinforcing sleeve; the second traveling device is disposed on the support plate and is used to drive the support plate to move on the beam; the reinforcing sleeve passes through the support plate along the thickness direction, and the reinforcing sleeve has a through second pin hole along the length direction.

[0010] Optionally, the end of the reinforcing sleeve facing the beam is spaced apart from the beam.

[0011] Optionally, the mobile trolley further includes a limiting member, which is connected to the support plate, and a portion of the limiting member is located on the side of the support plate away from the beam; a limiting space is formed between the limiting members of the two mobile trolleys.

[0012] Optionally, the transfer vehicle further includes a transition plate. Two parallel transition plates are provided on both ends of the beam along the width direction. The two parallel transition plates are spaced apart vertically and are used to guide the guide wheels and balance wheels of the bogie, respectively. One end of the transition plate away from the end face of the beam extends to the edge of the beam and is used to align with the end face of the track beam along the thickness direction. The other end is inclined toward the beam.

[0013] And / or, the beam is provided with guide plates on both ends of the beam along the width direction, the guide plates including a first plate and a second plate; the first plate is attached to one end of the beam along the thickness direction; along the length direction of the beam, one end of the second plate is connected to the first plate, and the other end of the second plate extends beyond the edge of the beam and is inclined away from the central axis of the beam.

[0014] Optionally, the first walking device includes a crossbeam and walking wheels; the middle part of the crossbeam is lower than the height of both ends of the crossbeam, and the beam body is installed in the middle part of the crossbeam; the two ends of the crossbeam are respectively connected to the walking wheels.

[0015] Secondly, the present invention provides a bogie transfer method, employing the bogie transfer fixture described above, comprising the following steps: The moving trolley is locked to the beam of the transfer vehicle using a locking device; The bogie is hoisted to the transfer vehicle, and the two moving trolleys respectively support the opposite ends of the bogie frame; Control the movement of the first traveling device of the transfer vehicle until the end face of the beam along the length direction is aligned with the end face of the track beam along the length direction; The locking device releases the locking of the moving trolley and the beam. Control the movement of the two mobile trolleys until the bogie is transferred onto the track beam; The two mobile trolleys are removed from the track beam and then locked back to the beam using the locking device.

Simultaneously, two moving trolleys are spaced apart along the length of the top of the beam, each supporting one end of the bogie frame. The moving trolleys are locked or unlocked to the beam via locking devices. When the moving trolleys and the beam are locked, the moving trolleys provide stable support for the bogie, reducing the probability of bogie swaying. When the moving trolleys and the beam are unlocked, the moving trolleys can move from the beam to the track beam, thereby moving the bogie onto the track beam. During this process, the bogie's wheel system rolls into contact with the track beam, reducing the probability of wheel system damage. In summary, compared to using lifting equipment to mount the bogie onto the track, the bogie transfer fixture of this invention not only improves the efficiency of bogie mounting but also reduces the probability of damage to the bogie's wheel system during mounting.

[0023] The bogie transfer fixture of this invention includes a transfer vehicle 100, a mobile trolley 200, and a locking device 300. The transfer vehicle 100 includes a beam 101 and a first traveling device 102. The first traveling device 102 is disposed on the beam 101 and is used to drive the beam 101 to move. Two mobile trolleys 200 are spaced apart along the length of the top of the beam 101. The two mobile trolleys 200 are configured to support the opposite ends of the frame 401 of the bogie 400, respectively. The mobile trolleys 200 are locked or unlocked to the beam 101 by the locking device 300. When the mobile trolleys 200 and the beam 101 are in the unlocked state, the mobile trolleys 200 can move on the beam 101.

[0024] Specifically, such as Figure 1 , 2 As shown, the beam 101 is a box-shaped structure, with a first traveling device 102 connected to the front and rear ends of its bottom surface to enable the beam 101 to travel. The top surface of the beam 101 is flat, and two moving trolleys 200 are spaced apart along the length direction (X-axis direction). The two moving trolleys 200 can support the opposite ends of the frame 401 of the bogie 400 respectively. At the same time, the two moving trolleys 200 are locked or unlocked to the beam 101 by locking devices 300 respectively. When the moving trolleys 200 and the beam 101 are in the unlocked state, the moving trolleys 200 can drive the bogie 400 to move along the length direction (Z-axis direction) of the beam 101.

[0025] In this embodiment, in the structure of the bogie transfer fixture, the first traveling device 102 of the transfer vehicle 100 can easily drive the beam 101 to a position aligned with the track beam, so that the bogie 400 on the transfer vehicle 100 is aligned with the track beam, thereby reducing the difficulty of aligning the bogie 400 with the track beam and improving work efficiency; at the same time, two moving trolleys 200 are spaced apart along the length of the top of the beam 101, and these two moving trolleys 200 can respectively support the opposite ends of the frame 401 of the bogie 400; due to the moving... The trolley 200 is locked or unlocked to the beam 101 via the locking device 300. When the trolley 200 and the beam 101 are locked, the trolley 200 can stably support the bogie 400, reducing the probability of bogie 400 swaying. When the trolley 200 and the beam 101 are unlocked, the trolley 200 can move from the beam 101 to the track beam, thereby driving the bogie 400 to move onto the track beam. During this process, the wheel system of the bogie 400 rolls into contact with the track beam, thus reducing the probability of wheel system damage. In summary, compared with using lifting equipment to load the bogie 400 onto the track, the bogie transfer fixture of the present invention not only improves the efficiency of loading the bogie 400 onto the track but also reduces the probability of damage to the wheel system of the bogie 400 during loading.

[0026] Optionally, the beam 101 is provided with a first pin hole 1011, and the moving trolley 200 is provided with a second pin hole 205; the locking device 300 includes a pin 301, which passes through the first pin hole 1011 and the second pin hole 205 to lock the beam 101 and the moving trolley 200.

[0027] Specifically, the number of the first pin hole 1011 and the second pin hole 205 is not specifically limited and depends on actual needs. For example... Figure 3 As shown, the top surface of the beam 101 is provided with two sets of first pin holes 1011 along the length direction (the direction of the X-axis), and each set of first pin holes 1011 has two first pin holes 1011; two moving trolleys 200 are respectively arranged corresponding to the two sets of first pin holes 1011, and each moving trolley 200 is provided with two second pin holes 205, which are respectively arranged corresponding to the two second pin holes 205 of the corresponding set of second pin holes 205; each moving trolley 200 is equipped with two locking devices 300. When in use, the pin shaft 301 of the locking device 300 passes through the corresponding first pin hole 1011 and second pin hole 205, which can realize the locking of the beam 101 and the moving trolley 200.

[0028] In this embodiment, since the beam 101 and the moving trolley 200 are respectively provided with a first pin hole 1011 and a second pin hole 205, the locking device 300 only needs to insert the pin shaft 301 into the corresponding first pin hole 1011 and second pin hole 205 simultaneously to complete the rigid locking, so that the moving trolley 200 and the beam 101 become one unit, and the bogie 400 will not slip or shake during transportation. Before the bogie 400 is placed on the rail, the pin shaft 301 can be pulled out to unlock the moving trolley 200 from the beam 101, and the moving trolley 200 can drive the bogie 400 to slide along the beam 101 to the rail beam without additional tools or complicated operations. This "one-insert-one-pull" pure mechanical locking scheme has a very simple structure and reliable operation, which not only ensures the stability and safety of the transportation process, but also significantly shortens the switching time between unlocking and placing on the rail, thereby further improving the overall operation efficiency.

[0029] Optionally, when the cross-sectional shape of the pin 301, the first pin hole 1011 and the second pin hole 205 is circular, the moving trolley 200 is locked or unlocked with the beam 101 by at least two pins 301.

[0030] Specifically, such as Figure 3 As shown, the cross-sectional shape of the pin 301, the first pin hole 1011 and the second pin hole 205 are all circular. The diameters of the first pin hole 1011 and the second pin hole 205 are equal, and the diameter of the pin 301 is slightly smaller than the diameters of the first pin hole 1011 and the second pin hole 205. Each moving trolley 200 is locked or unlocked to the beam 101 by two pins 301.

[0031] In this optional embodiment, the mobile trolley 200 is locked or unlocked to the beam 101 by at least two pins 301, which can form a multi-point positioning of the mobile trolley 200 to eliminate the rotational degree of freedom of the mobile trolley 200. This allows the mobile trolley 200 and the beam 101 to be rigidly locked in the longitudinal, lateral and torsional directions at the same time, so that there is no risk of shaking even if the bogie 400 is under heavy load. The circular hole shaft fit still retains the advantages of simple processing and easy insertion and removal, taking into account both high-precision positioning and quick assembly and disassembly.

[0032] In other embodiments, the cross-sectional shape of the pin 301, the first pin hole 1011, and the second pin hole 205 may also be non-circular, such as elliptical, square, or other irregular shapes. This is not limited and depends on actual needs. In this case, each moving trolley 200 is locked or unlocked to the beam 101 by a locking device 300.

[0033] Optionally, the locking device 300 also includes a hand-held component 302, which is disposed at one end of the pin 301 along the length direction.

[0034] Specifically, the handheld component 302 can be ring-shaped, straight, or U-shaped; there are no specific limitations, and the shape depends on the actual needs. For example... Figure 4 As shown, the handheld component 302 is ring-shaped and is located at one end of the pin 301 along the length direction (the direction of the Z-axis).

[0035] In this optional embodiment, after adding a hand-held part 302 to the end of the pin 301, the operator can directly hold the exposed hand-held part 302 to complete the insertion and removal, so that the pin 301 can be inserted into or removed from the first pin hole 1011 and the second pin hole 205. Compared with the situation where the operator holds the shaft of the pin 301 and it is difficult to bear the force, the difficulty of inserting and removing the pin 301 is significantly reduced.

[0036] Optionally, the mobile trolley 200 includes a support plate 201, a second traveling device 202, and a reinforcing sleeve 203; the second traveling device 202 is disposed on the support plate 201 and is used to drive the support plate 201 to move on the beam 101; the reinforcing sleeve 203 is inserted through the support plate 201 along the thickness direction of the support plate 201, and the reinforcing sleeve 203 is provided with a through second pin hole 205 along the length direction.

[0037] Specifically, such as Figure 5 As shown, in the structure of the mobile trolley 200, the support plate 201 is a flat plate structure, and a second walking device 202 is provided on its bottom end surface; two reinforcing sleeves 203 are provided along the thickness direction (Z-axis direction) of the support plate 201; the two reinforcing sleeves 203 are spaced apart, and a second pin hole 205 is provided along the length direction so that the pin shaft 301 can pass through.

[0038] In this optional embodiment, a reinforcing sleeve 203 is provided on the support plate 201, which can correspondingly increase the vertical length of the second pin hole 205. When the pin 301 is inserted, the shear force is shared by the support plate 201 and the reinforcing sleeve 203, and the specific pressure of the hole wall of the second pin hole 205 drops sharply, thereby increasing the stiffness and wear resistance life by a factor of two.

[0039] In this embodiment, the second walking device 202 includes a connecting seat 2021 and a roller 2022. The connecting seat 2021 is detachably connected to the support plate 201, and the roller 2022 is rotatably mounted on the connecting seat 2021.

[0040] Furthermore, the second walking device 202 also includes a drive motor, which is connected to the roller 2022 to enable the second walking device 202 to walk autonomously.

[0041] Optionally, the end of the reinforcing sleeve 203 facing the beam 101 is spaced apart from the beam 101.

[0042] Specifically, such as Figure 5 As shown, the reinforcing sleeve 203 is a straight cylinder, with its upper end passing through the support plate 201 and connected to the support plate 201, and its other end being spaced apart from the upper surface of the beam 101, with a distance of 1cm to 2cm between them.

[0043] In this optional embodiment, a gap is maintained at one end of the reinforcing sleeve 203 facing the beam 101, so that when the support plate 201 carries the bogie 400 through the second traveling device 202, the vertical load is completely transmitted by the second traveling device 202. The bottom end face of the reinforcing sleeve 203 does not contact the beam 101 and there is no sliding wear. After the pin 301 is inserted into the reinforcing sleeve 203, the reinforcing sleeve 203 only provides an additional bending arm length in the shear direction of the pin 301, without introducing additional frictional resistance. This ensures the high rigidity and long service life of the locking pair and avoids the end face of the reinforcing sleeve 203 from being bumped and deformed due to long-term slippage.

[0044] Optionally, the mobile trolley 200 also includes a limiting member 204, which is connected to the support plate 201, and part of the limiting member 204 is located on the side of the support plate 201 away from the beam 101; a limiting space is formed between the limiting members 204 of the two mobile trolleys 200.

[0045] Specifically, the limiting component 204 can be a rod or a plate; no specific restrictions are imposed here, and it depends on the actual needs. For example... Figure 5 As shown, the limiting member 204 is a rod, one end of which is vertically set on the upper end face of the support plate 201; and the limiting member 204 of the two moving trolleys 200 forms a limiting space, which is used to limit the front and rear end faces of the frame 401 of the bogie 400.

[0046] In this optional embodiment, after the bogie 400 is placed on the mobile trolley 200, its front and rear end faces are respectively abutted against the limiting members 204 of the two mobile trolleys 200. At this time, the longitudinal degree of freedom of the bogie 400 is restricted, and it can move synchronously with the mobile trolley 200 without additional straps or manual support, completely eliminating the risk of slippage caused by inertial impact and significantly improving the safety and efficiency of the upper rail operation.

[0047] Optionally, the transfer vehicle 100 also includes a transition plate 103. Two parallel transition plates 103 are provided on the two end faces of the beam 101 along the width direction. The two parallel transition plates 103 are spaced apart vertically and are used to guide the guide wheels 402 and balance wheels 403 of the bogie 400. One end of the transition plate 103 away from the end face of the beam 101 extends to the edge of the beam 101 and is used to align with the end face of the track beam along the thickness direction. The other end is inclined toward the beam 101.

[0048] It is important to understand that, during the design of the beam 101, the width of the beam 101 needs to be smaller than the distance between the two guide wheels 402 or the two balance wheels 403 of the bogie 400 along the Y-axis, so that the bogie 400 can be quickly hoisted onto the transfer car 100. At this time, the width of the beam 101 is also smaller than the width of the track beam. When the bogie 400 is transferred from the beam 101 to the track beam by the moving trolley 200, the position may need to be adjusted.

[0049] To solve the above problems, such as Figure 1 As shown, the beam 101 has two parallel transition plates 103 on both ends of its width direction (Y-axis direction). The transition plates 103 extend along the length direction (X-axis direction) of the beam 101. One transition plate 103 is used to cooperate with the guide wheel 402 of the bogie 400, and the other transition plate 103 is used to cooperate with the balance wheel 403 of the bogie 400. The end of the transition plate 103 away from the end face of the beam 101 extends to the edge of the beam 101 and is flush with the end face of the track beam along the thickness direction. The other end of the transition plate 103 away from the end face of the beam 101 is inclined toward the beam 101 so as to guide the guide wheel 402 or the balance wheel 403 of the bogie 400 to the part where the transition plate 103 is flush with the track beam.

[0050] In this optional embodiment, a transition plate 103 is added to the beam 101, which not only facilitates the quick alignment of the beam 101 with the track beam, but also facilitates the smooth movement of the guide wheel 402 or balance wheel 403 of the bogie 400 to the track beam.

[0051] Optionally, guide plates 104 are provided on both ends of the beam 101 along the width direction. The guide plate 104 includes a first plate 1041 and a second plate 1042. The first plate 1041 is attached to one end of the beam 101 along the thickness direction. Along the length direction of the beam 101, one end of the second plate 1042 is connected to the first plate 1041, and the other end of the second plate 1042 extends beyond the edge of the beam 101 and is inclined away from the central axis of the beam 101.

[0052] Specifically, the guide plates 104 on the end face of the beam 101 along the width direction (the direction of the Y-axis) can be one, two, or three, etc., without specific restrictions, depending on actual needs. For example... Figure 1 As shown, a guide plate 104 is provided on each of the two ends of the beam 101 along the width direction (the direction of the Y-axis). In the structure of the guide plate 104, one end of the first plate 1041 along the thickness direction (the direction of the Y-axis) is attached to one end of the beam 101 along the thickness direction. Along the length direction (the direction of the X-axis) of the beam 101, one end of the second plate 1042 is connected to the other end of the first plate 1041 along the thickness direction. The other end of the second plate 1042 extends beyond the edge of the beam 101 and is inclined away from the central axis of the beam 101. The inclination angle is not limited here and is determined according to actual needs.

[0053] In this optional embodiment, when the transfer vehicle 100 moves to the end of the track beam, the guide plates 104 on both ends of the beam 101 along the width direction first contact the track beam. The inclined second plate 1042 of the guide plate 104 can play a guiding role during the movement of the beam 101. The two second plates 1042 on both sides of the beam 101 can drive the beam 101 to be aligned, so as to realize the alignment of the beam 101 and the track beam until the ends of the beam 101 and the track beam are in contact.

[0054] Optionally, the first walking device 102 includes a crossbeam 1021 and walking wheels 1022; the middle part of the crossbeam 1021 is lower than the height of the two ends of the crossbeam 1021, and the beam body 101 is installed in the middle part of the crossbeam 1021; the two ends of the crossbeam 1021 are respectively connected to the walking wheels 1022.

[0055] Specifically, such as Figure 1 As shown, in the structure of the first walking device 102, the crossbeam 1021 is a beam structure that is low in the middle and high at both ends. The middle part of the crossbeam 1021 supports and connects to the lower end of the beam body 101. The two ends of the crossbeam 1021 are respectively connected to the walking wheels 1022, and the bottom end surface of the crossbeam 1021 is higher than the bottom end surface of the walking wheels 1022.

[0056] In this optional embodiment, the first traveling device 102 is designed to not only provide stable support for the beam 101, but also to reduce the height of the beam 101, thereby making the upper end face of the beam 101 flush with the upper end face of the track beam, thus ensuring that the moving trolley 200 drives the bogie 400 to transfer to the track beam.

[0057] Furthermore, the first walking device 102 also includes a drive motor, which is drivenly connected to the walking wheel 1022 to realize the autonomous walking of the first walking device 102.

[0058] The bogie transfer method of this invention adopts the bogie transfer fixture described above, such as... Figure 6 As shown, it includes the following steps: S100, The moving trolley 200 is locked to the beam 101 of the transfer vehicle 100 by the locking device 300; In step S100, two movable trolleys 200 are first placed on the top surface of the beam 101, and the second pin hole 205 of each movable trolley 200 is aligned vertically with the corresponding first pin hole 1011 on the beam 101. Then, the pin shaft 301 is respectively inserted into the corresponding first pin hole 1011 and second pin hole 205 to lock the two movable trolleys 200 with the beam 101.

[0059] S200, hoist the bogie 400 to the transfer vehicle 100, and make the two moving trolleys 200 support the opposite ends of the frame 401 of the bogie 400 respectively; In step S200, the bogie 400 is lifted above the transfer car 100 using a crane or other lifting equipment, and then the bogie 400 is lowered to the transfer car 100, so that two moving trolleys 200 support the opposite ends of the frame 401 of the bogie 400 respectively.
