Description

Technical Field

[0001] The invention belongs to the technical field of transportation, and in particular relates to a wire hanging method for installing a bogie of an empty rail transport vehicle into a box beam. Background Art

[0002] The domestic coal mining level is getting higher and higher, and the coal transported out of the coal mining plant is mostly transported by car and rail. At present, the basic coordination of coal mining is to transport the crushed fine coal from the coal mining area to the railway yard by car, and then convert it into long-distance railway transportation at the railway yard. The road conditions for car transportation are poor, the distance is long, the speed is limited, the maintenance cost of long-term heavy load on the road is high, the car transportation is greatly affected by weather factors, the regular transportation volume fluctuates greatly, and the overall efficiency is low. The emergence of magnetic drive sky rail is a good direction for solving the short-distance transportation of coal.

[0003] At present, the sky rail bogie adopts an integral frame, and the motor, brake equipment, running wheel pair and other structures are all installed on the same frame. When this type of bogie is installed into the box beam, it is difficult to compress it in height and cannot be installed as a whole. Each structure needs to be installed into the box beam separately, which makes the operation complicated. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the above-mentioned background technology and to provide a method for hanging wires for installing the bogie of an empty rail transport vehicle into a box beam.

[0005] The technical solution adopted by the present invention is: a method for hanging wires of a bogie of an empty rail collective motion vehicle into a box beam, wherein the bogie comprises a linear motor mover, a linear motor stator, a motor bracket, a frame, a positioning wheel set, a running wheel set, a compression spring device, a pull rod, a tread brake, a top rail brake, a current collector and a central suspension device;

[0006] The wire hanging process of the bogie being installed into the box beam includes:

[0007] Install the linear motor stator on the bottom of the top plate of the box beam and fix the frame on the tooling frame;

[0008] Install and fix the compression spring device on the frame to perform the first compression;

[0009] Install the traveling wheelset, longitudinal tie rod, tread brake, top rail brake, current collector and center suspension device on the frame respectively;

[0010] Install the linear motor mover and the positioning wheel pair on the motor bracket, install the motor bracket on the top of the compression spring device and connect it to the longitudinal pull rod;

[0011] The compression spring device is compressed for a second time, and the motor bracket and the frame are fixed for a second time;

[0012] Install the entire bogie into the box beam. After the running wheelset falls onto the running track, release the secondary fixation between the motor bracket and the frame, and slowly adjust the height of the compression spring device until the positioning wheelset is pressed onto the positioning track.

[0013] Furthermore, the step of fixing the compression spring device on the frame and compressing it for the first time comprises:

[0014] After the compression spring device is placed on the frame, external force is applied to the compression spring device to compress it to the corresponding height, and the pre-tightening bolt is passed through the frame and screwed into the compression spring device to fix and lock the height of the compression spring device, and then the applied external force is removed.

[0015] Furthermore, the compression spring device is compressed for a second time by applying an external force to the motor bracket, and the applied external force is removed after the motor bracket and the frame are fixed for a second time.

[0016] Furthermore, after the compression spring device is compressed for the second time, the pre-tightening bolt is adjusted to lock the height of the compression spring device after the second compression.

[0017] Furthermore, the secondary fixing of the motor bracket and the frame includes:

[0018] The first lifting lug on the motor bracket and the second lifting lug on the frame are tied and fixed together by a steel wire rope to achieve secondary fixation of the motor bracket and the frame.

[0019] Furthermore, the height of the compression spring device is slowly adjusted by slowly screwing out the pre-tightening bolt.

[0020] Furthermore, after the positioning wheel pair is pressed onto the positioning rail, the pre-tightening bolts are removed.

[0021] Furthermore, before removing the pre-tightening bolts, detect the actual air gap between the linear motor mover and the linear motor stator. If the actual air gap exceeds the set air gap range, adjust the actual air gap. After the adjustment is completed, remove the pre-tightening bolts.

[0022] Further, the adjusting the actual air gap includes:

[0023] The compression spring device is highly compressed by adjusting the pre-tensioning bolt;

[0024] Screw the adjustment rod into the adjustment threaded tube of the positioning wheel guide frame seat on the motor bracket, lift up the positioning wheel pair, and add or remove several height adjustment gaskets in the second limiting circular groove of the positioning wheel guide frame seat;

[0025] Unscrew the adjusting rod, the positioning wheel pair falls back into the positioning wheel guide frame seat, complete the air gap adjustment, and unscrew the pre-tightening bolt.

[0026] Furthermore, the actual air gap between the linear motor mover and the linear motor stator is detected by a gap detection sensor on the linear motor mover.

[0027] The beneficial effects of the present invention are:

[0028] The linear motor mover and motor bracket of the present invention adopt a floating type in the vertical direction, and the working clearance between the motor mover and the motor stator is controlled by a positioning wheel to ensure the driving force of the linear motor; four sets of pre-compression spring devices are used to make the motor bracket and the linear motor mover in a floating state. Therefore, when the bogie is transferred into the box beam, other tools can be used to assist in the quick and convenient compression of the bogie height in advance, so that it can be reduced to the minimum height, so that it can be smoothly installed into the box beam cavity.

[0029] The method of the present invention is simple to operate, and basically does not add other mechanisms, and does not affect the lifting of the bogie. After the bogie is installed in the box-type track beam, it is also easy to remove the fixing parts and restore the floating state of the linear motor.

[0030] The method for compressing the height of the bogie of the present invention will not affect the assembly structure of the bogie. After the entire bogie is fully assembled, a lowering operation is performed, and then the spring compression amount is fixed to limit the spring rebound, thereby achieving the purpose of lowering the height of the entire bogie, and therefore the assembly structure of the bogie will not be changed.

[0031] After the bogie height is compressed by the method of the present invention, the operation of releasing the bogie height compression is also simple. Since the space inside the box-type track beam is small and the operating space is limited, after compression by this method, only a bolt wrench is needed to release the compression state, which is very suitable for operation in narrow spaces.

[0032] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0059] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0060] It should be understood that the term “and / or” used in the specification and appended claims of this application refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0061] In addition, in the description of the present application and the claims, the terms "first", "second", "third", "top", "bottom", "one side", "the other side", "one end", "the other end", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. For example, without departing from the scope of this specification, the first component can be called the second component, and similarly, the second component can be called the first component. The components at the top and the bottom can also be swapped or converted with each other under certain circumstances; the components at one end and the other end can have the same or different performances.

[0062] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0063] In the case of using "including", "having" and "comprising" described in this specification, unless used, there may also be another part or other parts, and the terms used may generally be singular but may also represent plural forms. In the description of this specification, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, when constituting a component, although there is no clear description thereof, it can be understood that a certain error area must be included.

[0064] When describing a positional relationship, for example, when the positional sequence is described as "on," "above," "below," and "next," unless words or terms such as "just" or "directly" are used, situations where they are not in contact or in contact may also be included. If a first element is mentioned to be "on" a second element, it does not mean that the first element must be above the second element in the figure. The upper and lower parts of the component will change depending on the change in the angle of observation and orientation. Therefore, in the drawings or in the actual construction, if it is mentioned that the first element is "on" the second element, it may include a situation where the first element is "below" the second element and a situation where the first element is "above" the second element.

[0065] The present invention provides a method for hanging wires of a bogie of an empty rail transport vehicle into a box beam, wherein the bogie is a linear motor driven bogie, and is a matching design for a magnetic drive standard empty rail transport vehicle (empty rail container transport vehicle), such as Figure 1-3 As shown, the bogie includes a linear motor mover, a linear motor stator, a motor bracket, a frame, a positioning wheel set, a walking wheel set, a compression spring device, a pull rod, a tread brake, a top rail brake, a current collector and a central suspension device.

[0066] The process of hanging wires for loading the bogie into the box beam is as follows:

[0067] Stator fixing: The linear motor stator 2 is installed on the bottom of the top plate of the box beam by bolts.

[0068] Placement: First, when assembling the linear motor driven bogie, it needs to be fixed on the tooling frame. Fix the frame 5 on the tooling frame. Before installing the linear motor mover 1 and the motor bracket 4, place the four groups of compression spring devices 8 stably on the spring fixing seat 5.12 on the frame 5. At this time, external force is applied to the upper ends of the four groups of compression spring devices 8 simultaneously to compress the compression springs to the same height.

[0069] Fixing: There is a through hole 5.12.2 at the bottom center of each compression spring device on the frame 5. A pre-stressing bolt 16 is used to connect with the internal threaded hole 8.8 of the pre-stressing screw of the upper clamping plate 8.2 through the through hole. Tightening the pre-stressing bolt 16 can constrain and fix the compression spring device 8 on the frame 5. The screwed-in state of the pre-stressing bolt 16 is shown in FIG. Figure 7 At the same time, the compression height of the compression spring device can be adjusted to a suitable position to facilitate the subsequent installation of the motor bracket and longitudinal tie rod.

[0070] Re-compression: When the entire bogie is assembled, in order to fit the entire bogie into the box-type track beam, it is necessary to apply external force to the motor bracket again to lower the height of the bogie again. At the same time, adjust the pre-compression bolt 16 to fix the compression amount of the compression spring device so that the height of the entire bogie is lowered to a suitable height size.

[0071] Secondary fixation: Considering safety, it is not very safe to bear the compression reaction force of the spring that compresses the entire bogie only through four pre-tightening bolts 16. Maintain the external force applied by the outside during recompression, and then use the wire rope 18 to tie and fix the second lifting lug 5.1.1 on the frame 5 beside the four sets of compression spring devices and the first lifting lug 4.1.1 on the motor bracket 4 firmly. The state of the wire rope 18 is as follows: Figure 4 As shown, the bundling wire rope bears the main spring compression reaction force, and the external force applied by the outside is removed after the bundling is completed.

[0072] Dismantling and recovery: After the bogie is successfully loaded into the box track beam, first untie the wire rope 18 between the second lifting ear 5.1.1 of the binding frame and the first lifting ear 4.1.1 of the motor bracket, and the first constraint on the height of the frame 5 and the motor bracket 4 is released. At this time, the pre-tightening bolt 16 is still compressing the spring, and then the pre-tightening bolt 16 at the compression spring device is slowly adjusted synchronously, such as Figure 5 As shown, the compressed spring is slowly compressed until the positioning wheel presses against the positioning track, and then the four pre-tightening bolts are directly removed to restore the linear motor and motor bracket of the bogie to a floating state, as shown in FIG. Figure 6 shown.

[0073] In some embodiments, before removing the pre-tightening bolts, the gap detection sensor 3 is used to detect the actual air gap between the linear motor mover 1 and the linear motor stator 2 (including the linear motor stator and both ends of the mover), and the actual air gap is compared with the set air gap range. If the actual air gap at the corresponding end exceeds the set air gap range, it means that the height of the motor bracket 4 may be too high or too low, resulting in the distance between the linear motor mover 1 and the linear motor stator 2 being too small or too large, and the difference is recorded; the actual air gap needs to be adjusted, and the pre-tightening bolts are removed after the adjustment is completed. Exceeding the set air gap range means that the actual air gap is greater than the upper limit of the set air gap range or less than the lower limit of the set air gap range.

[0074] It can be understood that the air gap adjustment process includes: compressing the compression spring device 8 by adjusting the pre-tightening bolt 16. The compression of the compression spring device is a rough adjustment of the motor bracket height, and fine adjustment is performed after the motor bracket height drops.

[0075] Screw the special adjustment rod 17 that can cooperate with the adjustment threaded tube 4.8.6 into the adjustment threaded tube 4.8.6 of the positioning wheel guide frame seat 4.8 on the motor bracket 4. Figure 8 As shown, the positioning wheel pair 6 is lifted up, and a number of height adjustment gaskets 6.10 are added or removed from the second limiting circular groove 4.8.4 of the positioning wheel guide frame seat 4.8 according to the excess error of the air gap in the initial state. The purpose of adjusting the air gap between the mover and the stator of the linear motor can be achieved by adjusting the height of the positioning wheel pair relative to the motor bracket. The positioning wheel pair 6 is lifted up here not to increase the height of the positioning wheel pair, but relative to the motor bracket, because the top of the positioning wheel is in contact with the positioning guide rail of the box beam, and its height will not change. Therefore, when the adjusting rod 17 is adjusted, the height of the motor bracket 4 is lowered, and the height of the positioning wheel pair 6 is raised relative to the motor bracket. At this time, since the adjusting rod 17 is against the positioning wheel pair, there is a certain distance between the shock-absorbing spring 6.8 of the positioning wheel pair and the second limiting circular groove 4.8.4 of the positioning wheel guide frame seat, a suitable number of height adjustment gaskets 6.10 can be added or removed. The number of height adjustment gaskets added or removed is determined according to the difference between the actual air gap initially detected and the set air gap range. If the actual air gap is greater than the upper limit value of the set air gap range, the difference is the difference between the actual air gap and the upper limit value of the set air gap range; if the actual air gap is less than the lower limit value of the set air gap range, the difference is the difference between the upper limit value of the set air gap range and the actual air gap.

[0076] After adding or removing the height adjustment gasket, screw out the adjustment rod 17, the positioning wheel pair 6 falls back into the positioning wheel guide frame seat 4.8, or the motor bracket height is increased, the positioning wheel guide frame seat rises and engages with the positioning wheel, and then screw out the pre-tightening bolt to release the height compression of the compression spring device to complete the air gap adjustment.

[0077] In some embodiments, various structures of the bogie are further described below.

[0078] The linear motor mover 1 is located below the linear motor stator 2 and maintains a fixed gap with the linear motor stator 2 to ensure that the motor has a stable electromagnetic driving force. When powered on, the current generated in the coil of the linear motor stator 2 will generate a magnetic field, which interacts with the permanent magnet on the linear motor mover 1, thereby generating an electromagnetic force to drive the linear motor mover 1 to move in a linear direction. The linear motor is used as a drive, and stable power can be provided in the drive. The front and rear ends of the linear motor mover 1 are provided with a gap detection sensor 3, and the gap detection sensor 3 can detect the air gap between the linear motor mover 1 and the linear motor stator 2 in real time. When the air gap is not within the set range, it can be adjusted in time. The motor bracket 4 is suspended and connected above the frame 5 through the compression spring device 8 and the longitudinal pull rod 9. The linear motor mover 1 and the positioning wheel pair 6 are installed on the motor bracket 4, and the walking wheel pair 7, the tread brake 10, the top rail brake 11, the current collector 12 and the center suspension device 13 are all installed on the frame 5. After the bogie is installed in the box beam, the positioning wheels 6.1 of the positioning wheel set 6 cooperate with the positioning guide rail 15.2, and the running wheels 7.2 of the running wheel set 7 cooperate with the running guide rail 15.3.

[0079] The main structure of the bogie of the present invention includes two parts: a motor bracket 4 and a frame 5. Various devices are installed on the motor bracket 4 and the frame 5 respectively. Four compression spring devices 8 are used for balanced support in the vertical direction between the motor bracket 4 and the frame 5, so that the motor bracket forms a floating state, ensuring that the linear motor mover and the stator are maintained in a fixed induction gap range; longitudinal pull rods 9 are used to hinge the frame 5 and the motor bracket 4 in the front and rear longitudinal directions to transmit driving force or electric braking force; in the lateral direction, the lateral displacement is limited by the wheel flange and the rail structure of the upper steel wheel and rail combination, which not only meets the small lateral displacement difference between the frame and the linear motor support frame when turning, but also meets the synchronization of the lateral displacement of the linear motor support frame and the frame during movement.

[0080] In some embodiments, Figure 9-12As shown, the motor bracket 4 includes two side beams 4.1 arranged opposite to each other, the middle parts of the two side beams 4.1 are connected by a load-bearing crossbeam 4.2, the ends of the two side beams 4.1 are connected by an end crossbeam 4.3, a large crossbeam 4.4 is arranged between the load-bearing crossbeam 4.2 and the end crossbeam 4.3, a first tie rod seat 4.5 is arranged at the bottom of the end crossbeam 4.3, one end of the longitudinal tie rod 9 is hingedly connected to the first tie rod seat 4.5, and a spring top plate is arranged at the bottom of the large crossbeam 4.4 The top of the compression spring device 8 is connected to the spring top plate seat 4.6, the side beam 4.1 is located between the large cross beam 4.4 and the end cross beam 4.3 and is partially concave to form a recessed portion 4.7, and the recessed portion 4.7 is provided with a positioning wheel guide frame seat 4.8, and the positioning wheel pair 6 is installed in the positioning wheel guide frame seat 4.8, and the top of the load-bearing cross beam 4.2 and the top of the end cross beam 4.3 are provided with a mover fixing seat 4.9, and the linear motor mover 1 is installed on the mover fixing seat 4.9.

[0081] It is understandable that the motor bracket 4 is used to carry the linear motor mover 1 and the positioning wheel set 6, and the side beams 4.1 and multiple cross beams provided therein can ensure good bearing capacity. The recessed portions 4.7 at both ends of the side beam 4.1 and the positioning wheel set guide frame seat 4.8 provided in the recessed portions facilitate the installation of the positioning wheel set.

[0082] It should be noted that the above-mentioned side beam 4.1 is a tubular structure composed of structural plates connected by welding or other means, and the transverse plate of the tubular structure has a protruding portion at the edge connected to the vertical plate to enhance the structural strength. Multiple crossbeams are also similar structures. For example, the load-bearing crossbeam 4.2 includes multiple single beams arranged at intervals. The single beam is composed of a transverse plate and a vertical plate to form an I-shaped structure, and the two ends are fixedly connected to the inner side of the longitudinal beam. That is, whether it is a longitudinal beam or a cross beam, the structure is a non-uniform structure, and the edges of the structure have protruding parts or concave parts to achieve a function similar to a reinforcing rib plate. The first lifting lug 4.1.1 is provided on the outer side of the front and rear ends of the side beam 4.1. The first lifting lug 4.1.1 is convenient for moving and lifting the motor bracket, and can also perform secondary fixation on the bogie when the bogie is installed in the box beam.

[0083] It can be understood that the first tie rod seat 4.5 is used for hinged connection with the top end of the longitudinal tie rod 9. The first tie rod seat 4.5 includes two first fixing plates 4.5.1, each of which is provided with two first fixing holes 4.5.2, and the longitudinal tie rod 9 is connected with the first fixing holes 4.5.2 by bolts. The spring top plate seat 4.6 contacts the top surface of the upper clamping plate 8.2 of the compression spring device 8, and is used to limit the displacement of the compression spring device 8 in all directions. The spring top plate seat 4.6 includes a first limiting circular groove 4.6.1, which can be formed by a retaining ring provided on the surface of the large cross beam 4.4, or by a depression on the surface of the large cross beam 4.4. Two mover fixing seats 4.9 are arranged on each end cross beam 4.3, and two mover fixing seats 4.9 are arranged on the bearing cross beam. To ensure the structural strength, the two mover fixing seats 4.9 on the bearing cross beam are installed on the same base plate seat. The mover fixing seat 4.9 comprises a second fixing plate 4.9.1, and two second fixing holes 4.9.2 are arranged on the second fixing plate 4.9.1, which is fixedly connected to the linear motor mover 1 through the second fixing holes 4.9.2 and bolts.

[0084] It can be understood that there are four positioning wheel guide frame seats 4.8, which are respectively installed with four positioning wheels (two positioning wheel pairs). Its structural design facilitates the installation of the positioning wheel pair 6 and can also adjust the air gap of the linear motor, including a first contact portion 4.8.1 and a second contact portion 4.8.2 arranged relatively, the first contact portion 4.8.1 and the second contact portion 4.8.2 are respectively attached to the side of the recessed portion 4.7, and the middle parts of the first contact portion 4.8.1 and the second contact portion 4.8.2 are each provided with a first limiting vertical groove 4.8.3, the first limiting vertical groove 4.8.3 separates the corresponding contact portion into two wedge-shaped structures, a second limiting circular groove 4.8.4 is arranged between the first contact portion 4.8.1 and the second contact portion 4.8.2, and a through recessed groove 4.8.5 is opened in the center of the second limiting circular groove 4.8.4, and an adjusting threaded tube 4.8.6 that penetrates the recessed portion 4.7 is connected to the bottom of the recessed groove 4.8.5.

[0085] When installing the positioning wheel set 6, the bearing saddle 6.5 on the positioning wheel set 6 is clamped between the first contact portion 4.8.1 and the second contact portion 4.8.2, and the limiting boss 6.11 cooperates with the first limiting vertical groove 4.8.3 to limit the lateral displacement of the positioning wheel set; the bottom end of the damping spring 6.8 at the bottom of the bearing saddle 6.5 cooperates with the second limiting circular groove 4.8.4, and the limiting rod 6.9 is located in the sink 4.8.5. In order to ensure the installation accuracy, a number of longitudinal adjustment gaskets 6.12 can be arranged between the limiting boss 6.11 and the corresponding contact portion, and a number of height adjustment gaskets 6.10 can be arranged between the limiting rod 6.9 and the second limiting circular groove 4.8.4; the adjusting threaded tube 4.8.6 at the bottom of the sink 4.8.5 is convenient for inserting the adjusting rod 17 when adjusting the air gap, and the top of the adjusting rod 17 is against the bottom of the limiting rod 6.9.

[0086] In some embodiments, as Figure 13-17 shown, the above-mentioned frame 5 includes two double-web longitudinal beams (i.e., double longitudinal beams) 5.1 arranged oppositely. A concave load-bearing platform 5.2 is arranged between the middle parts of the two double-web longitudinal beams 5.1. The load-bearing platform 5.2 divides each double-web longitudinal beam 5.1 into two segments. A strengthening cross beam 5.3 is arranged between the ends of the two double-web longitudinal beams 5.1. Top rail brake mounting seats 5.4 for mounting top rail brakes 11 are respectively arranged on the outer sides of the two ends of the top of the double-web longitudinal beam 5.1. Wheel guide frame seats 5.5 for mounting wheel pairs 7 are respectively arranged at the two ends of the bottom of the double-web longitudinal beam 5.1. Current collector mounting seats 5.6 for mounting current collectors 12 are respectively arranged on both sides of the load-bearing platform 5.2. A center pin cylinder 5.7 for mounting a center suspension device 13 is arranged in the middle of the load-bearing platform 5.2. A plurality of bolster spring limit seats 5.8 and a plurality of bolster swing limit seats 5.9 are arranged around the center pin cylinder 5.7. Tread brake mounting seats 5.10 for mounting tread brakes 10 are respectively arranged on both sides of the bottom of the strengthening cross beam 5.3. A second tie rod seat 5.11 is arranged at the inner end of the top of the strengthening cross beam 5.3. A spring fixing seat 5.12 is arranged at the top of the strengthening cross beam 5.3.

[0087] The frame 5 of this embodiment is different from the frame of a common freight train bogie. This frame adopts double longitudinal beams with double webs and strengthening cross beams at both ends. The middle part of the whole frame is concave, serving as a load-bearing platform for bolster center suspension. There is a tread brake mounting arm at each of the four end corners, and there is a mounting bracket for top rail brake on the side of the middle part from the center to the end of the longitudinal beam. The whole frame looks like an "M" shape when viewed frontally and an "O" shape when viewed from above. The whole structure has good stability and strong load-bearing capacity. Two types of braking units are installed and arranged on the frame. There are 8 installation positions for braking units on the frame, including 4 installation positions for tread brakes of steel wheels and 4 installation positions for top rail brakes for parking brakes. It has obvious advantages in braking performance compared with traditional trains during transportation on large slopes.

[0088] The compression spring device 8 is in contact with the component 5. However, in order to keep the spring stable and immovable, a plug hole 5.3.1 is arranged on the strengthening cross beam 5.3 of the frame to prevent the horizontal movement of the spring. At the same time, through the through plug hole 5.3.1, when initially installed, the pre-compressed spring device can be compressed to a certain height by using a long pre-tightening bolt, which is convenient for the whole bogie to be installed into the box-shaped track beam.

[0089] It can be understood that the double-web longitudinal beam 5.1 is a double longitudinal plate cavity beam formed by connecting a plate-like structure, and various specifications of ribs are arranged inside. The position 5.1.2 where the double-web longitudinal beam 5.1 connects with the load-bearing platform 5.2 is a downward curved arc structure with a smooth transition to enhance the bearing capacity of the frame. The double-web longitudinal beam is a non-uniform structure in structure, and the edges of the structure are all protruding parts or concave parts to achieve a function similar to a reinforcing rib plate. The reinforcing crossbeam is a tubular structure with a hollow interior. A second lifting lug 5.1.1 is provided at the connection position between the top of the double-web longitudinal beam 5.1 and the reinforcing crossbeam. The second lifting lug 5.1.1 is convenient for moving the lifting frame and can also perform secondary fixation on the bogie when the bogie is loaded into the box beam.

[0090] It can be understood that the bearing platform 5.2 is an internally hollow frame structure formed by connecting plate-like structures, the current collector mounting seat 5.6 is arranged on both sides of the top of the bearing platform, the center pin tube 5.7 passes through the bearing platform, the rocker spring limit seat 5.8 is arranged on the top of the bearing platform, and the rocker swing limit seat 5.9 is arranged at the position where the top of the bearing platform is connected to the double web longitudinal beam.

[0091] It can be understood that the top rail brake mounting seat 5.4 includes a first mounting plate 5.4.1, a first supporting plate 5.4.2 and a plurality of second supporting plates 5.4.3, the first mounting plate 5.4.1 is provided with a plurality of first mounting holes 5.4.4 for mounting the top rail brake, the first mounting plate 5.4.1 is fixed parallel to the outer plate of the double-web longitudinal beam, the first supporting plate 5.4.2 is vertically fixed to one side of the first mounting plate 5.4.1, the bottom of the first supporting plate 5.4.2 is fixedly connected to the double-web longitudinal beam, the second supporting plate 5.4.3 is fixed to the inner side of the first mounting plate 5.4.1 and is perpendicular to the first mounting plate 5.4.1 and the top of the double-web longitudinal beam, the first mounting plate 5.4.1 is supported by the first supporting plate 5.4.2 and the second supporting plate 5.4.3, and the stability of the installation of the top rail brake can be ensured.

[0092] It is understandable that, in order to facilitate the regular disassembly and maintenance of the wheelset and the rapid assembly, a running wheel guide frame seat 5.5 consisting of two special-shaped fixed blocks is adopted, with a total of four in two groups. The primary suspension spring 7.1 of the wheelset and the wheelset can be quickly installed in the guide frame seat. Compared with the traditional bogie, it is extremely convenient to disassemble and replace the wheelset and the primary spring device. Specifically, the running wheel guide frame seat 5.5 includes a relatively arranged special-shaped first contact plate 5.5.1 and a second contact plate 5.5.2, a third limiting circular groove 5.5.5 is set between the first contact plate 5.5.1 and the second contact plate 5.5.2, a third support plate 5.5.3 is vertically fixed on the side of the first contact plate 5.5.1 away from the second contact plate 5.5.2; a fourth support plate 5.5.4 is vertically fixed on the side of the second contact plate 5.5.2 away from the first contact plate 5.5.1, and the first contact plate 5.5.2 and the second contact plate are both provided with a second limiting vertical groove 5.5.6 with a top opening. When installing the traveling wheelset, a series of spring devices of the traveling wheelset (i.e., the load-bearing saddle, the damping spring, etc.) are clamped between the first contact plate 5.5.1 and the second contact plate 5.5.2, and the limiting boss cooperates with the second limiting vertical groove 5.5.6 to limit the lateral displacement of the traveling wheelset; the bottom end of the damping spring at the bottom of the load-bearing saddle cooperates with the third limiting circular groove 5.5.5. To ensure the installation accuracy, a number of longitudinal adjustment gaskets may be arranged between the limiting boss and the corresponding contact portion, and a number of height adjustment gaskets may be arranged between the limiting rod and the third limiting circular groove.

[0093] It is understandable that the current collector mounting seat 5.6 can fix and adjust the position of the current collector 12 so that the current collector 12 is in constant contact with the third rail (power rail 15.4) on the track beam to supply power to the linear motor. Specifically, the current collector mounting seat 5.6 includes a second mounting plate 5.6.1 and a plurality of fifth support plates 5.6.2, the second mounting plate 5.6.1 is provided with a plurality of second mounting holes 5.6.3, the second mounting plate 5.6.1 is vertically fixed to the top side edge of the bearing platform 5.2, and the fifth support plates 5.6.2 are vertically fixed to the two sides and the bottom of the second mounting plate 5.6.1.

[0094] It should be noted that in order to realize the assembly connection between the frame 5 and the center suspension device 13, as well as buffering and shock absorption, a spring pad and a retaining ring are provided on the concave platform in the middle of the frame 5. The lower end of the bolster rubber spring contacts the spring pad and is horizontally restricted in the spring retaining ring. The upper end of the rubber spring supports the upper end of the bolster and the center pin, and there are also spring pads and retaining rings to limit horizontal displacement. The center pin vertically passes through the center of the frame, and a center pin cylinder is set at the center of the frame. There is an annular ball joint rubber sleeve for shock absorption and limiting between the center pin cylinder and the center pin. A rubber spring is passed between the bolster and the center pin and the frame, and a ball joint rubber sleeve is passed between the center pin and the center sleeve of the center pin cylinder of the frame to avoid direct contact between steel and steel, and at the same time ensure that the center suspension device can have a small displacement in each degree of freedom.

[0095] It can be understood that the center pin barrel 5.7 is a stepped hole with a large diameter at the lower end 5.7.2 and a small diameter at the upper end 5.7.1, and a plurality of axially arranged guide grooves 5.7.3 are provided on the hole wall at the upper end along the circumference. When installing the center suspension device 13, the center pin shaft passes through the center pin barrel, and there is an annular ball joint rubber sleeve sleeved on the center pin shaft between the two. The ball joint rubber sleeve is interference fit with the center pin barrel, and the diameter of the lower half of the center pin barrel in contact with the ball joint rubber sleeve is larger than the diameter of the upper half, forming a step, which abuts against the upper end surface of the ball joint rubber sleeve to prevent the center suspension device from moving upward when the vehicle brakes suddenly. Rectangular grooves are provided on the four directions of the upper half of the center pin barrel, which is convenient for pushing the ball joint rubber sleeve that is interference fit with the center pin barrel out of the lower half of the center pin barrel by external force, and replacing the new ball joint rubber sleeve.

[0096] It can be understood that the rocker spring limit seat 5.8 set on the bearing platform 5.2 is used to limit the horizontal displacement of the cylindrical rubber spring. Specifically, the rocker spring limit seat 5.8 includes a spring retaining ring 5.8.1 and a first spring pad 5.8.2 protruding from the surface of the bearing platform. The spring retaining ring 5.8.1 is arranged around the first spring pad 5.8.2. The spring retaining ring limits the horizontal displacement. The spring pad is a rubber pad, which plays a buffering role and also avoids contact with the steel structure. The bolster swing limit seat 5.9 arranged around the bearing platform 5.2, and the rubber stopper thereon are used for cushioning the swing of the bolster during movement to avoid direct collision with the frame steel structure. Specifically, the bolster swing limit seat 5.9 comprises a third mounting plate 5.9.1, a sixth support plate 5.9.2 and a rubber stopper (not shown in the figure). The third mounting plate 5.9.1 is vertically fixed to the top of the bearing platform, and the sixth support plate 5.9.2 is vertically fixed to the side of the third mounting plate 5.9.1 away from the center pin tube, and is connected to the top surface of the longitudinal beam and the first support plate at the same time to enhance the structural stability. The rubber stopper is fixed to the third mounting plate.

[0097] It can be understood that the tread brake mounting seat 5.10 is used to install the tread brake 10, which includes a downwardly inclined support rod 5.10.1 and a fourth mounting plate 5.10.2, the top of the support rod 5.10.1 is fixed to the bottom of the reinforcing beam 5.3, and the fourth mounting plate 5.10.2 is fixed to the outer side of the bottom of the support rod 5.10.1, and the fourth mounting plate 5.10.2 is provided with a plurality of third mounting holes. The second tie rod seat 5.11 is used to be hingedly connected to the other end of the longitudinal tie rod 9, and includes an L-shaped third fixing plate 5.11.1 and a seventh support plate 5.11.2. The bottom of the third fixing plate 5.11.1 is fixed to the top of the reinforcing beam 5.3. A U-shaped groove 5.11.3 is opened in the middle of the side of the third fixing plate 5.11.1, and third fixing holes 5.11.4 are respectively provided on both sides of the side of the third fixing plate 5.11.1. The seventh support plate 5.11.2 is vertically fixed to the third fixing plate 5.11.1.

[0098] It can be understood that the spring fixing seat 5.12 includes a second spring washer 5.12.1 fixed to the top of the reinforcing cross beam 5.3, a through hole 5.12.2 is opened in the center of the second spring washer 5.12.1, and a through plug hole 5.3.1 is provided on the reinforcing cross beam 5.3 at a position corresponding to the through hole. The spring fixing seat 5.12 is used to connect with the bottom of the compression spring device 8. During installation, the lower clamping plate 8.3 of the compression spring device 8 contacts the second spring washer 5.12.1, and the latch 8.10 passes through the through hole 5.12.2 and is inserted into the plug hole 5.3.1 on the reinforcing cross beam 5.3. When it is necessary to adjust the air gap of the linear motor or install the bogie, the pre-tightening bolt 16 can be connected to the compression spring device 8 through the spring fixing seat 5.12 to compress its height.

[0099] In some embodiments, Fig.18 As shown, the positioning wheel pair 6 includes an axle 6.2 and positioning wheels 6.1 respectively fixed to the two ends of the axle, and the two ends of the axle 6.2 are respectively provided with fixing parts 6.3 on the inner side of the positioning wheels, and the fixing parts 6.3 include a bearing 6.4, a load-bearing saddle 6.5, a front stop 6.6 and a rear stop 6.7. The inner ring of the bearing 6.4 is fixed on the axle 6.2, and the load-bearing saddle 6.5 is in contact connection or interference fit with the lower part of the outer ring of the bearing 6.4. The front stop 6.6 and the rear stop 6.7 are respectively arranged on both sides of the bearing 6.4, and are limited by the inner limiting step of the axle and the inner side surface of the positioning wheel. The bottom and side of the load-bearing saddle 6.5 are connected to the positioning wheel guide frame seat 4.8 of the motor bracket 4. A downwardly protruding limit rod 6.9 is provided at the bottom of the shock absorbing spring 6.8 at the bottom of the bearing saddle 6.5, and a plurality of height adjustment gaskets 6.10 are sleeved on the limit rod 6.9. A limit boss 6.11 is provided on the side of the bearing saddle 6.8, and a plurality of longitudinal adjustment gaskets 6.12 are sleeved on the limit boss 6.11.

[0100] It should be noted that the structure of the traveling wheelset 7 is basically the same as that of the positioning wheelset 6. The difference is that when the air gap of the linear motor is adjusted, it is necessary to adjust it through the positioning wheelset 6, and the traveling wheelset does not have this function. Therefore, a limit rod 6.9 is provided at the bottom of the bearing saddle of the positioning wheelset 6, while no limit rod is provided at the bottom of the traveling wheelset 7.

[0101] In some embodiments, Fig.19 As shown, the compression spring device 8 comprises a pre-compression spring 8.1, an upper clamping plate 8.2, a lower clamping plate 8.3, a buffer rubber pad 8.4 and a pressure ring 8.5 with a T-shaped cross section. The bottom surface of the upper clamping plate 8.2 is provided with a first protruding circular ring 8.6, and the middle part of the bottom surface of the upper clamping plate 8.2 is provided with a downward pre-tightening screw 8.7, and the bottom of the pre-tightening screw 8.7 is provided with a longer threaded hole 8.8.

The pressure ring 8.5 is sleeved on the outside of the second protruding circular ring 8.9 and contacts the top of the buffer rubber gasket 8.4. The bottom of the pre-compression spring 8.1 is sleeved on the outside of the second protruding circular ring 8.9 and contacts the top surface of the pressure ring 8.5.

[0102] When the compression spring device 8 is in a normal state on the bogie, the bottom end of the pre-tightening screw 8.7 is located in the second protruding ring 8.9 and is spaced a certain distance from the top surface of the lower clamping plate 8.3 or flush with the top surface of the second protruding ring 8.9. When the compression spring device 8 needs to be compressed, a long pre-tightening bolt 16 is passed through the insertion hole 8.11, and the top of the pre-tightening bolt 16 is matched with the threaded hole 8.8. The deeper the pre-tightening bolt 16 is screwed in, the greater the height of the compression spring device 8 is compressed. Fig.15 FIG. 1 is a schematic diagram of the pre-tightening bolt 16 being screwed into the compression spring device 8 . The length of the threaded hole in the figure is only for illustration and is actually determined according to the possible compression height of the compression spring device.
