DETAILED DESCRIPTION

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] like Figure 1-5As shown, the present invention provides a structure of a linear motor driven bogie of an aerial rail transport vehicle (i.e., an aerial rail container transport vehicle), comprising two double-web longitudinal beams (i.e., double longitudinal beams) 1 arranged opposite to each other, a concave bearing platform 2 is arranged between the middle parts of the two double-web longitudinal beams 1, the bearing platform 2 divides each double-web longitudinal beam 1 into two sections, a reinforcing crossbeam 3 is arranged between the ends of the two double-web longitudinal beams 1, top rail brake mounting seats 4 for mounting top rail brakes are respectively arranged on the outer sides of the top ends of the double-web longitudinal beams 1, and the bottom ends of the double-web longitudinal beams 1 are provided with a plurality of reinforcing crossbeams 3. Travel wheel guide frame seats 5 for installing travel wheel pairs are respectively arranged; current collector mounting seats 6 for installing current collectors are respectively arranged on both sides of the bearing platform 2, a center pin cylinder 7 for installing a center suspension device is arranged in the middle of the bearing platform 2, and a plurality of rocker spring limit seats 8 and a plurality of rocker swing limit seats 9 are arranged around the center pin cylinder 7; tread brake mounting seats 10 for installing tread brakes are respectively arranged on both sides of the bottom of the reinforced cross beam 3, a longitudinal pull rod seat 11 is arranged at the inner end of the top of the reinforced cross beam 3, and a spring fixing seat 12 is arranged at the top of the reinforced cross beam 3.

[0037] The present invention serves as a load-bearing structural member and also as a fixing base for the bogie attachments, and has multiple functions;

[0038] Load-bearing: This frame is designed for the magnetic drive standard air rail linear motor driven bogie for coal transportation on high altitude, large drop and large slope routes in coal mines. It can adapt well to the box-type rail beams of the air rail, as well as the support motor bracket and linear motor. When running on a large slope, the bogie frame must have sufficient load-bearing capacity. This frame is different from the frame of the bogie of an ordinary freight train. The bogie frame adopts a double longitudinal sealing plate cavity beam with double webs, and various specifications of stiffeners inside to enhance the load-bearing capacity of the frame. There are transverse rectangular reinforced end beams at both ends. The middle part of the whole frame is concave, which serves as the load-bearing platform surface for the center suspension of the bolster. The whole structure has good stability and strong load-bearing capacity.

[0039] Installation and fixation: According to the characteristics of the bogie linear motor drive and the application conditions. The support and connection of the linear motor and motor bracket, the installation and fixation of various brake units, and the power supply device will be on the frame. There is a tread brake mounting seat inclined downward at each of the four end corners of the frame. The middle position from the center of the longitudinal beam to the end and the outer side are provided with a top rail brake mounting support. The whole frame is similar to an "M" shape when viewed from the front and a "sun" shape when viewed from above; there are current collector fixing seats on both sides of the concave bearing platform surface in the middle of the middle part, which can fix and adjust the position of the current collector so that the current collector and the third rail (power supply rail) on the track beam are in constant contact to supply power to the linear motor.

[0040] 3. Maintenance: In order to facilitate the regular disassembly and maintenance and rapid assembly of the wheelset, a walking wheel guide frame seat consisting of two special-shaped fixed blocks is adopted, with a total of four groups. The primary spring device of the wheelset and the wheelset can be quickly installed into the guide frame seat.

[0041] 4. Linear motor clearance control: The linear motor needs to control the clearance between the linear motor mover and the stator (or permanent magnet) to ensure the motor's efficient output of stable driving force. The frame, motor bracket and linear motor mover are floating in the vertical direction. Pre-compression springs are used to support the frame and the motor bracket. The longitudinal tie rod seats in the longitudinal and transverse directions are provided on the inner side of the two double longitudinal beams on the cross beam at the end of the frame. The component and the motor bracket can be hinged by the tie rod. The motor bracket and the component are relatively fixed in the transverse and longitudinal directions. The positioning wheel on the motor bracket is pressed on the inner surface of the top plate of the track beam. Through the action of the pre-compression spring and the positioning wheel, the linear motor mover is always suspended above the frame, and a stable gap is maintained between the linear motor mover and the stator (or permanent magnet).

[0042] The compression spring device is in contact with the component, but in order to keep the spring stable and not move, a plug hole 3.1 is set on the reinforcing crossbeam 3 of the frame to avoid horizontal movement of the spring. At the same time, through the through plug hole 3.1, the pre-compression spring device can be compressed to a certain height by using a long pre-tightening bolt during the initial installation, so as to facilitate the installation of the entire bogie into the box-type track beam.

[0043] It can be understood that the double-web longitudinal beam 1 is a double longitudinal closed plate cavity beam formed by connecting a plate-like structure, and various specifications of ribs are arranged inside. The position 1.2 where the double-web longitudinal beam 1 is connected to the load-bearing platform 2 is a downward curved arc structure with a smooth transition to enhance the load-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 lifting lug 1.1 is provided at the connection position between the top of the double-web longitudinal beam 1 and the reinforcing crossbeam. The lifting lug 1.1 is convenient for moving the lifting frame and can also perform secondary fixation on the bogie when the bogie is installed in the box beam.

[0044] It can be understood that the supporting platform 2 is an internally hollow frame structure formed by connecting plate-like structures, the current collector mounting seat 6 is arranged on both sides of the top of the supporting platform, the center pin tube 7 passes through the supporting platform, the rocker spring limit seat 8 is arranged on the top of the supporting platform, and the rocker swing limit seat 9 is arranged at the position where the top of the supporting platform is connected to the double web longitudinal beam.

[0046] 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 consisting of two special-shaped fixed blocks is adopted, with a total of four in two groups. The primary suspension springs and wheelset of the running wheel set can be quickly installed into the guide frame seat, and 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 includes a first contact plate 5.1 and a second contact plate 5.2 that are arranged in a special shape relative to each other, and a limiting circular groove 5.5 is set between the first contact plate 5.1 and the second contact plate 5.2. A third support plate 5.3 is vertically fixed on the side of the first contact plate 5.1 away from the second contact plate 5.2; a fourth support plate 5.4 is vertically fixed on the side of the second contact plate 5.2 away from the first contact plate 5.1, and both the first contact plate 5.2 and the second contact plate are provided with a limiting vertical groove 5.6 with a top opening. When installing the traveling wheelset, a series of suspension springs of the traveling wheelset (i.e., the load-bearing saddle, the damping spring, etc.) are clamped between the first contact plate 5.1 and the second contact plate 5.2, and the limiting boss cooperates with the limiting vertical groove 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 limiting circular groove 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.

[0047] It can be understood that the current collector mounting seat 6 can fix and adjust the position of the current collector so that the current collector and the third rail (power rail) on the track beam are in constant contact with each other to supply power to the linear motor.

[0048] It should be noted that in order to realize the assembly connection between the frame and the center suspension device, 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. 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, while ensuring that the center suspension device can have a small displacement in each degree of freedom.

[0049] It can be understood that the center pin barrel 7 is a stepped hole with a large diameter at the lower end 7.2 and a small diameter at the upper end 7.1, and a plurality of axially arranged guide grooves 7.3 are provided on the hole wall at the upper end along the circumference. When installing the center suspension device, 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.

[0050] It can be understood that the bolster spring limit seat 8 provided on the bearing platform 2 is used to limit the horizontal displacement of the cylindrical rubber spring. Specifically, the bolster spring limit seat 8 includes a spring retaining ring 8.1 and a first spring pad 8.2 protruding from the surface of the bearing platform. The spring retaining ring 8.1 is arranged around the first spring pad 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 9 provided around the bearing platform 2 has a rubber stopper thereon for buffering the swing of the bolster during movement to avoid directly hitting the frame steel structure. Specifically, the bolster swing limit seat 9 includes a third mounting plate 9.1, a sixth support plate 9.2 and a rubber stopper (not shown in the figure). The third mounting plate 9.1 is vertically fixed to the top of the bearing platform.

During installation, the lower clamping plate 8 of the compression spring device contacts the second spring pad 12.1, and the latch passes through the through hole 12.2 and is inserted into the plug hole 3.1 on the reinforcing cross beam 3. When it is necessary to adjust the air gap of the linear motor or install the bogie, the pre-tightening bolt can be connected to the compression spring device through the spring fixing seat to compress its height.
