Description

Technical Field

[0001] The utility model relates to the technical field of flatbed truck bogies, in particular to a special flatbed truck bogie frame. Background Art

[0002] The bogie frame is an important component of the flatbed truck. It is a body used to carry and transmit force. It transmits the vertical load of the car body and withstands the upward force from the wheels. It also withstands the traction or braking force generated by the traction or braking of the flatbed truck. Therefore, it needs to have sufficient strength and rigidity.

[0003] In the related technology, the bogies of flatbed cars are currently usually the bogies of railway mainline locomotives, passenger cars and freight cars. The strength and rigidity of the bogies cannot meet the use requirements of flatbed cars, which can easily cause deformation or damage to the bogies, increase the maintenance and replacement costs of the bogies, and there is a safety hazard of flatbed car derailment. At the same time, the space of the flatbed car bogie is small, and most of the existing bogie frames cannot meet the installation space requirements of the bogies.

[0004] Therefore, a special flatbed truck bogie frame is urgently needed to meet the use requirements of the flatbed truck when it is in working state and the installation space requirements of the bogie. Utility Model Content

[0005] The purpose of the utility model is to provide a special flatbed truck bogie frame to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A special flatbed truck bogie frame, comprising:

[0008] A frame body, wherein end beams are respectively arranged at both ends of the frame body, a left beam and a right beam are respectively arranged on both sides of the frame body, a traction beam is arranged between the left beam and the right beam, and a motor is arranged at the bottom of the traction beam;

[0009] Two sets of guide frames are respectively arranged at the lower parts of the left beam and the right beam, wherein the guide frames are provided with a hollow cavity in the middle, and axle boxes are respectively arranged in the hollow cavities of the guide frames on both sides, and a wheel set is arranged between the axle boxes on both sides;

[0010] A central rotating seat is arranged in the middle of the traction cross beam, and a rotating device is arranged on the top of the central rotating seat.

[0011] The special flatbed truck bogie frame according to this solution has at least the following technical effects:

[0012] The special flatbed car bogie frame is provided with a traction beam between the left beam and the right beam of the frame body, two groups of guide frames are respectively provided at the lower parts of the left beam and the right beam, a hollow cavity is provided in the middle part of the guide frame, axle boxes are provided in the hollow cavities of the guide frames on both sides, a pair of wheels is provided between the axle boxes on both sides, and a center swivel seat is provided in the middle part of the traction beam, and a swivel device is provided on the top of the center swivel seat, so that the frame can effectively bear the vertical load of the car body and its upper equipment and the force transmitted upward by the pair of wheels, can withstand the traction or braking force generated by the traction or braking of the flatbed car, enhance the carrying capacity of the flatbed car under various road conditions, improve the strength and rigidity of the bogie frame, and ensure the stability of the flatbed car operation; at the same time, when passing through a curved section, the swivel device rotates and displaces to achieve safe passing of the curve, can effectively control safety accidents such as rail derailment at the position of the track with a small curvature radius, and improve the safety of the flatbed car operation, and the frame structure is simple and compact, which can meet the installation requirements of the space inside the flatbed car bogie.

[0013] As a further solution of the utility model: rubber springs are respectively arranged on the tops of both sides of the hollow cavity of the guide frame, and the guide frame is connected to the axle box through the rubber springs.

[0014] Since rubber springs are respectively arranged on the tops of both sides of the hollow cavity of the guide frame, the guide frame is connected to the axle box through the rubber springs, which can effectively position the axle box in the hollow cavity of the guide frame, help to evenly distribute the load of the axle box, reduce the local pressure on the axle box, and can buffer the impact and vibration of the flatbed car during operation, thereby improving the comfort and stability of the flatbed car during operation.

[0015] As a further solution of the utility model: limiting columns are respectively arranged at the bottom of both sides of the hollow cavity of the guide frame, a limiting plate is arranged at the bottom of the axle box, and both ends of the limiting plate are respectively arranged on the limiting columns on both sides.

[0016] Since limiting columns are respectively arranged at the bottom of both sides of the hollow cavity of the guide frame, limiting plates are arranged at the bottom of the axle box, and both ends of the limiting plates are respectively arranged on the limiting columns on both sides, the axle box can be effectively limited in the hollow cavity of the guide frame to prevent the axle box from shaking or swinging when the flatbed car is running, causing the axle box to be displaced, ensuring the stability of the connection of the axle box, thereby improving the operation stability and reliability of the flatbed car.

[0017] As a further solution of the utility model: the limit column is made of rubber material.

[0018] Since the limit column is made of rubber material, it has good elasticity and buffering performance, which helps to absorb impact force or vibration and reduce the impact on the axle box and guide frame. At the same time, it can improve the wear resistance of the limit column and avoid long-term contact between the limit plate and the limit column causing wear on both, further improving the stability of the axle box when the flatbed car is running and extending its service life.

[0019] As a further solution of the utility model: rib plates are provided on both sides of the guide frame, and the rib plates are connected to the frame body.

[0020] By setting ribs on both sides of the guide frame and connecting the ribs to the frame body, the load can be better dispersed and transferred, which effectively enhances the strength of the guide frame and keeps it stable under high-intensity working conditions, improves the impact resistance and vibration resistance of the guide frame, and further improves the overall stability of the frame.

[0021] As a further solution of the utility model: brake hangers are respectively arranged at the bottom of the end beams at both ends, and brake devices are arranged at the bottom of the brake hangers.

[0022] Since brake mounts are respectively arranged at the bottom of the end beams at both ends and brake devices are arranged at the bottom of the brake mounts, the installation stability of the brake devices is effectively improved, and the brake devices are better integrated into the frame, making the frame more compact, effectively utilizing the bottom space of the frame, and improving the integration of the frame.

[0023] As a further solution of the utility model: a torque arm is provided on one side of the braking device, and the torque arm is connected to the wheelset.

[0024] Since a torque arm is provided on one side of the braking device and the torque arm is connected to the wheelset, the force generated by the braking device can be more effectively transmitted to the wheelset, thereby enhancing the braking effect. The torque generated during braking can be controlled, thereby reducing the structural deformation caused by braking, greatly improving the braking efficiency of the flatbed truck, and thus improving the operating safety of the flatbed truck.

[0025] As a further solution of the utility model: the middle part of the left beam and the middle part of the right beam are respectively set as downward convex structures, and the side walls on both sides of the downward convex are respectively connected to one side of the two groups of guide frames.

[0026] Since the middle part of the left beam and the middle part of the right beam are respectively set as downward convex structures, and the side walls on both sides of the downward convex structures are respectively connected to one side of the two groups of guide frames, the overall bearing capacity and connection strength of the frame can be effectively enhanced, and it is helpful to transfer the load on the guide frame to the left beam and the right beam, reduce local stress concentration, further enhance the stability of the frame, and ensure the smooth operation of the flatbed truck.
