Description

Technical Field

[0001] This utility model belongs to the field of transportation technology, specifically relating to the structure of a linear motor driven bogie for a monorail integrated vehicle. Background Technology

[0002] With increasingly advanced coal mining techniques, coal transportation from mines often relies on a combination of trucks and railways. Currently, the basic method involves trucks transporting crushed fine coal from the mine to railway storage yards, where it is then transferred to long-distance rail transport. However, truck transport suffers from poor road conditions, long distances, speed restrictions, high maintenance costs due to heavy road loads, significant weather-related disruptions, large fluctuations in transport volume, and overall low efficiency. The emergence of magnetically driven overhead rail systems offers a promising solution for short-to-medium distance coal transshipment.

[0003] Currently, the bogie frame of the air rail adopts an integral frame, with the motor, braking equipment, and running wheelset all installed on the same frame. The air rail constructed by this type of frame has poor climbing performance and cannot adapt to large coal mines with large altitude differences between coal mines and coal transport railway stations.

Detailed Implementation

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model 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 and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may 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 avoid obscuring the description of the present application with unnecessary detail.

[0032] It should be understood that the term "and / or" as used in this application specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0033] Furthermore, in the description of this application and the claims, the terms "first," "second," "third," "top," "bottom," "one side," "the other side," "one end," "the other end," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. For example, without departing from the scope of this specification, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component. Top and bottom components may, in certain circumstances, be interchanged or converted from each other; components at one end and at the other end may have the same or different performance characteristics.

[0034] When using the terms "comprising," "having," and "including" as described in this specification, another part or other components may be included unless used. The terms are generally singular but can also represent plural forms. In the description of this specification, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, when constructing components, although not explicitly described, it is understood that a certain margin of error is necessarily included.

[0035] When describing positional relationships, for example, when the positional order is described as "on," "above," "below," and "next," situations where they are not in contact or are in contact may be included, unless words or terms such as "exactly" or "directly" are used. If it is said that the first element is "on" the second element, it does not mean that the first element must be above the second element in the drawing. The upper and lower parts of the components will change depending on the viewing angle and orientation. Therefore, in the drawings or in the actual construction, the situation where the first element is "on" the second element can include situations where the first element is "below" the second element and situations where the first element is "above" the second element.

[0036] like Figure 1-5As shown in the figure, the utility model provides a frame of a linear motor-driven bogie for an air track container movement vehicle (i.e., an air track container transport motor car), which includes two double-web longitudinal beams (i.e., double longitudinal beams) 1 arranged oppositely. 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 segments. A strengthening cross beam 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 two ends of the top of the double-web longitudinal beam 1. Wheel guide frame seats 5 for mounting running wheel sets are respectively arranged at the two ends of the bottom of the double-web longitudinal beam 1. Current collectors mounting seats 6 for mounting current collectors are respectively arranged on both sides of the bearing platform 2. A center pin cylinder 7 for mounting a center suspension device is arranged in the middle of the bearing platform 2. A plurality of bolster spring limit seats 8 and a plurality of bolster swing limit seats 9 are arranged around the center pin cylinder 7. Tread brake mounting seats 10 for mounting tread brakes are respectively arranged on both sides of the bottom of the strengthening cross beam 3. A longitudinal tie rod seat 11 is arranged at the inner end of the top of the strengthening cross beam 3. A spring fixing seat 12 is arranged at the top of the strengthening cross beam 3.

[0037] As a bearing structure member of the utility model, it is also the fixed foundation of the bogie accessories and has multiple functions;

[0038] Bearing: This frame is designed for the magnetic drive type air track linear motor-driven bogie for coal transportation on coal mine routes with high altitude, large drop and large slope roads. It can well adapt to the air track box-shaped track beam, and support the motor bracket and the linear motor. When running on a large slope, the bogie frame must have sufficient bearing capacity. This frame is different from the frame of the ordinary freight train bogie. In this bogie frame, a double-web double longitudinal sealing plate cavity beam is adopted, with various specifications of stiffeners inside to strengthen the bearing capacity of the frame. There are transverse rectangular strengthening end beams at both ends. The middle part of the whole frame is concave, serving as the bearing platform surface for the bolster center suspension. The whole structure has good stability and strong bearing capacity.

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

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

[0041] 4. Linear Motor Clearance Control: To ensure efficient and stable output of driving force, the clearance between the linear motor's mover and stator (or permanent magnet) needs to be controlled. The frame, motor support, and linear motor mover are vertically floating. A pre-compression spring supports the frame and motor support. Longitudinal tie rods are located on the inner sides of the two double longitudinal beams on the frame's end beam. These tie rods allow the component to be hinged to the motor support. The motor support and component are relatively fixed in both the transverse and longitudinal directions. Positioning wheels on the motor support press against the inner surface of the track beam's top plate. Through the action of the pre-compression spring and positioning wheels, the linear motor mover remains suspended above the frame, ensuring a stable clearance between the linear motor mover and 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 provided on the reinforcing crossbeam 3 of the frame to prevent the spring from moving horizontally. At the same time, through the plug hole 3.1, the pre-compression spring device can be compressed to a certain height by using long pre-tightening bolts during the initial installation, which facilitates the installation of the entire bogie into the box girder.

[0043] It is understood that the double-web longitudinal beam 1 is a double longitudinal sealed-plate cavity beam formed by connecting plate-like structures, with various specifications of stiffening plates inside. The position 1.2 where the double-web longitudinal beam 1 connects to the bearing platform 2 is a downwardly curved arc structure with a smooth transition, enhancing the load-bearing capacity of the frame. The double-web longitudinal beam is structurally non-uniform, with protruding or concave edges to achieve a function similar to stiffening plates. The reinforcing crossbeam is a hollow tubular structure. 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 facilitates the movement of the hoisting frame and also provides secondary fixation for the bogie when it is installed into the box girder.

[0044] It is understood that the bearing platform 2 is a hollow square frame structure formed by connecting plate-like structures. The current receiver mounting base 6 is located on both sides of the top of the bearing platform. The central pin cylinder 7 penetrates the bearing platform. The rocker spring limiting seat 8 is located on the top of the bearing platform. The rocker swing limiting seat 9 is located at the position where the top of the bearing platform connects with the double web longitudinal beam.

[0045] It is understood that the top rail brake mounting base 4 includes a first mounting plate 4.1, a first support plate 4.2, and several second support plates 4.3. The first mounting plate 4.1 is provided with several first mounting holes 4.4 for mounting the top rail brake. The first mounting plate 4.1 is fixed parallel to the outer side plate of the double web longitudinal beam. The first support plate 4.2 is fixed vertically to one side of the first mounting plate 4.1. The bottom of the first support plate 4.2 is fixedly connected to the double web longitudinal beam. The second support plates 4.3 are fixed to the inner side of the first mounting plate 4.1 and perpendicular to the top of the first mounting plate 4.1 and the double web longitudinal beam. The first mounting plate 4.1 is supported by the first support plate 4.2 and the second support plate 4.3, which can ensure the stability of the top rail brake installation.

[0046] Understandably, to facilitate regular disassembly and maintenance and quick assembly of the wheelsets, a travel wheel guide frame seat 5 composed of two irregularly shaped fixed stops is adopted, with a total of four in two sets. The primary suspension springs of the travel wheelsets and the wheelsets can be quickly installed into the guide frame seat. Compared with traditional bogies, disassembling and replacing the wheelsets and primary spring devices becomes extremely convenient. Specifically, the travel wheel guide frame seat 5 includes an irregularly shaped first contact plate 5.1 and a second contact plate 5.2 arranged opposite to each other. A limiting circular groove 5.5 is provided 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. Both the first contact plate 5.2 and the second contact plate are provided with limiting vertical grooves 5.6 with top openings. When installing the wheelset, the primary suspension springs (i.e., load-bearing saddle, damping spring, etc.) of the wheelset are engaged between the first contact plate 5.1 and the second contact plate 5.2. The limiting boss and the limiting vertical groove 5.6 cooperate to limit the lateral displacement of the 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 installation accuracy, several longitudinal adjustment shims can be set between the limiting boss and the corresponding contact part, and several height adjustment shims can be set between the limiting rod and the third limiting circular groove.

[0047] Understandably, the current collector mounting base 6 can fix and adjust the position of the current collector, ensuring that the current collector maintains constant contact with the third rail (power supply rail) on the track beam to supply power to the linear motor. Specifically, the current collector mounting base 6 includes a second mounting plate 6.1 and several fifth support plates 6.2. The second mounting plate 6.1 is provided with several second mounting holes 6.3. The second mounting plate 6.1 is vertically fixed to one edge of the top of the bearing platform 2, and the fifth support plates 6.2 are vertically fixed to the sides and bottom of the second mounting plate 6.1.

[0048] It should be noted that, in order to achieve the assembly and connection of the frame with the central suspension device, and for shock absorption, a spring pad and a retaining ring are provided on the recessed platform in the middle of the frame. The lower end of the bolster rubber spring contacts the spring pad and is horizontally restricted within the spring retaining ring. The upper end of the rubber spring supports the upper end of the bolster and the central pin, and is also restricted by the spring pad and retaining ring to limit horizontal displacement. The central pin vertically passes through the center of the frame, and a central pin sleeve is set at the center of the frame. A shock-absorbing and limiting annular ball joint rubber sleeve is placed between the central pin sleeve and the central pin. The bolster and central pin are connected to the frame by rubber springs, and the central pin is connected to the central sleeve of the frame's central pin sleeve by a ball joint rubber sleeve, avoiding direct contact between steel and steel, while ensuring that the central suspension device can have slight displacement in each degree of freedom.

[0049] It is understood that the center pin cylinder 7 is a stepped hole with a larger diameter at the lower end 7.2 and a smaller diameter at the upper end 7.1. Multiple axially arranged guide grooves 7.3 are provided at intervals along the circumference of the upper end hole wall. When installing the center suspension device, the center pin passes through the center pin cylinder, and an annular ball joint rubber sleeve is fitted between them. The ball joint rubber sleeve and the center pin cylinder are interference-fitted. The lower half of the center pin cylinder in contact with the ball joint rubber sleeve has a larger diameter than the upper half, forming a step that abuts against the upper end face of the ball joint rubber sleeve, preventing the center suspension device from moving upwards during sudden braking. Rectangular grooves are opened in four directions on the upper half of the center pin cylinder to facilitate the replacement of the ball joint rubber sleeve by pushing it out of the lower half of the center pin cylinder with external force.

[0050] It is understood that the rocker spring limiting seat 8 set on the bearing platform 2 is used to limit the horizontal displacement of the cylindrical rubber spring. Specifically, the rocker spring limiting seat 8 includes a spring retaining ring 8.1 protruding from the surface of the bearing platform and a first spring pad 8.2. The spring retaining ring 8.1 is arranged around the first spring pad 8.2. The spring retaining ring limits the horizontal displacement, and the spring pad is a rubber pad, which plays a buffering role and also avoids contact with the steel structure. The rocker swing limiting seat 9 set around the bearing platform 2 has rubber blocks on it to buffer the rocker swing during movement and avoid direct collision with the frame steel structure. Specifically, the rocker swing limiting seat 9 includes a third mounting plate 9.1, a sixth support plate 9.2 and rubber blocks (not shown in the figure). The third mounting plate 9.1 is vertically fixed to the top of the bearing platform, and the sixth support plate 9.2 is vertically fixed to the side of the third mounting plate 9.1 away from the central pin cylinder, and is connected to the top surface of the longitudinal beam and the first support plate to enhance structural stability. The rubber blocks are fixed to the third mounting plate.

[0051] It is understood that the tread brake mounting base 10 is used to install the tread brake 10, and it includes a downwardly angled support rod 10.1 and a fourth mounting plate 10.2. The top of the support rod 10.1 is fixed to the bottom of the reinforcing beam 3, and the fourth mounting plate 10.2 is fixed to the outer side of the bottom of the support rod 10.1. The fourth mounting plate 10.2 is provided with a plurality of third mounting holes. The longitudinal tie rod seat 11 is used to be hinged to the lower end of the longitudinal tie rod, and it includes an L-shaped third fixing plate 11.1 and a seventh support plate 11.2. The bottom of the third fixing plate 11.1 is fixed to the top of the reinforcing beam 3, and a U-shaped groove 11.3 is opened in the middle of the side of the third fixing plate 11.1. Third fixing holes 11.4 are respectively provided on both sides of the side of the third fixing plate 11.1. The seventh support plate 11.2 is vertically fixed to the third fixing plate 11.1.

[0052] It is understood that the spring fixing seat 12 includes a second spring pad 12.1 fixed to the top of the reinforcing crossbeam 3. The second spring pad 12.1 has a through hole 12.2 in its center, and the reinforcing crossbeam 3 has a through insertion hole 3.1 at a position corresponding to the through hole. The spring fixing seat 12 is used to connect to the bottom of the compression spring device 8. During installation, the lower clamping plate 8 of the compression spring device contacts the second spring pad 12.1, and the pin passes through the through hole 12.2 and is inserted into the insertion hole 3.1 on the reinforcing crossbeam 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.

[0053] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Contents not described in detail in this specification belong to prior art known to those skilled in the art.
