Description

Technical Field

[0001] The utility model relates to a suspended monorail vehicle bogie transport placement device, in particular to a suspended monorail vehicle bogie transfer placement rack, belonging to the field of urban rail transit. Background Art

[0002] A suspended monorail vehicle is a new type of rail vehicle in which the vehicle body is suspended below the box-beam track beam, with transport achieved through a bogie connected to the vehicle body. As a crucial component of the vehicle, the bogie's performance is crucial, responsible for the vehicle's traction, transmission, and braking functions. During bogie assembly and relocation, a set of tooling is required to support the bogie and ensure efficient and convenient assembly and transportation.

[0003] At present, in the rail transit industry, only traditional wheel-rail trains have dedicated bogie transfer and placement racks, while there are no bogie transfer and placement racks for suspended monorail vehicles. Summary of the Invention

[0004] The utility model is aimed at the deficiencies of the existing technology. The utility model aims to design a transfer and placement rack suitable for the bogie of a suspended monorail vehicle, which can realize the placement of the bogie during the assembly process and the placement and fixation of the bogie during the overall transportation process, so that the assembly and transportation of the bogie are safe and efficient.

[0005] This type of suspended monorail vehicle bogie transfer rack includes, from bottom to top, the following components:

[0006] Support frame: The support crossbeam and the support longitudinal beam are fixedly connected to form the bottom support frame. The distance between the two sets of support frames in the support frame is consistent with the wheelbase of the bogie, and plays the main role of bearing load;

[0007] Support columns: The support columns are fixedly installed above the intersection of the support beam and the support longitudinal beam. The support columns and the support beam form a door-shaped structure;

[0008] Support platform: The support platform is fixedly installed on the top of the support column;

[0009] Hanger fixing device: When the bogie is transported, the hanger fixing device connects the hanger to the suspension beam through an axle pin to prevent the bogie from shaking freely during transportation.

[0010] For further optimization, a reinforcement plate is provided at the connection between the support column and the support frame.

[0011] Further optimized, the support seat of the support platform is fixedly installed on the support column, the support surface is installed above the support seat, and the wheel limiting device is fixedly installed on the support surface.

[0012] Further optimized, the lateral limit stop and the longitudinal limit stop of the wheel limit device are fixedly installed on the supporting surface.

[0013] Further optimized, the connecting ear of the hanger fixing device is installed on the hanging beam, a support plate is set on the installation groove of the hanging beam, and the support plate is locked with the hanging beam through a nut.

[0014] For further optimization, transfer lugs are provided on the support columns.

[0015] The advantages of the utility model are: 1. it meets the placement and transportation requirements of the suspension vehicle bogie; 2. it realizes the longitudinal and transverse fixing requirements of the bogie; 3. it facilitates the assembly of the suspension vehicle bogie.

[0020] A suspended monorail vehicle bogie transfer and placement rack will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 3 As shown, this suspended monorail vehicle bogie transfer and placement rack adopts a modular and lightweight design. The overall structure consists of a support frame 1, support columns 2, support platform 3, and hanger fixing device 4. The main connection method is bolt connection, which facilitates disassembly and assembly while better realizing the adjustment of the platform installation size. From bottom to top, it includes:

[0022] Support frame 1: The bottom support frame 1 is composed of a fixed connection between the support crossbeam and the support longitudinal beam. The spacing between the two sets of support frames in support frame 1 matches the bogie wheelbase, and they primarily bear the load. Support frame 1 is composed of I-beams, which are connected and fixed using bolts. Angle steel structures are installed between the I-beams to provide strength reinforcement. The spacing between the two sets of support crossbeams in support frame 1 matches the bogie wheelbase, and they primarily bear the load.

[0023] Support column 2: Support column 2 is fixedly installed above the intersection of the support beam and the support longitudinal beam. The support column 2 and the support beam form a door-shaped structure. A reinforcement plate is provided at the connection between the support column 2 and the support frame 1;

[0024] The support platform 3 is fixedly mounted on the top of the support column 2. The support seat 31 of the support platform 3 is composed of an I-beam and a channel steel. The support column 2 and the I-beam crossbeam of the support seat 31 together form a door-type structure to jointly carry the bogie. The channel steel of the support seat 31 is welded to the I-beam crossbeam to strengthen the bending moment resistance of the support platform 3 and prevent the support platform 3 from being deformed by force. The support surface 32 is the contact surface between the bogie wheel and the tooling. The support surface 32 and the I-beam crossbeam and the channel steel adopt a welded structure to enhance the stability of the structure. Two groups of long holes are provided on the support surface 32 for installing and adjusting the transverse and longitudinal limit stops 33 of the wheels, 4 wheel longitudinal limit stops 33 and 4 wheel transverse limit stops 33. The 8 stops are fixed to the support surface 32 through the long holes on the support plate with bolts. The bogie is fixed to the tooling by adjusting the transverse or longitudinal position of the stop.

[0025] Hanger fixing device 4: When the bogie is transported, the hanger fixing device 4 connects the hanger to the suspension beam 42 through an axle pin to prevent the bogie from shaking freely during transportation. The hanger is part of the bogie and is the lowest part of the bogie. If it is not fixed during transportation, the bogie will shake. The hanger fixing device 4 is used to fix the hanger to the suspension beam 42 to prevent free shaking during transportation. The connecting ear 41 of the hanger fixing device 4 is installed on the suspension beam 42. A support plate 43 is set on the installation groove of the suspension beam 42. The support plate 43 is locked to the suspension beam 42 by a nut 44. The main body of the device is a square steel structure with a support plate 43 installation groove in the middle. The support plate 43 is connected to the suspension beam 42 using a threaded connection. The height of the support plate 43 can be adjusted by rotating the nut 44 below the support plate 43. Connecting ears 41 are set at both ends of the suspension beam 42 and can be connected to the hanger of the bogie through a pin shaft. After the hanger fixing device 4 is fixed to the hanger, the hanger is fixed to the suspension beam 42 by adjusting the height of the support plate 43.

[0026] In order to facilitate the movement of the bogie placement frame during transportation, a transportation lug 5 is provided on the support column 2.

[0027] The above are specific embodiments of the present invention and the technical principles used. Any modifications or equivalent transformations based on the technical solutions of the present invention should be included in the protection scope of the present invention.
