Description

Technical Field

[0001] The present application relates to the field of railway machinery design and manufacturing, and in particular to a track flaw detection vehicle frame and a flaw detection vehicle. Background Art

[0002] At present, the main method of rail damage detection at home and abroad is to use rail flaw detection vehicles for detection. The frame of the flaw detection vehicle is the carrier for installing the driver's cab, working device, power system, hydraulic system, pneumatic system and electrical system, ensuring the correct relative position of each part of the flaw detection vehicle and bearing its force. Therefore, the design and assembly of the frame occupies a very important position in the design and manufacture of the whole vehicle. The existing frame usually adopts an integral structure. According to the design of the whole vehicle, the complete frame of the frame is first welded and manufactured, and then the bottom plate impact seat and other structures are added to complete the production of the entire frame.

[0003] The disadvantages of this solution are: the frame part of the frame adopts an integrated welded structure. Because of its large size, the overall structure involves too many processing positions, so the welding process is complicated and the workload is large during production and processing. In addition, the material is heavy and errors are prone to occur during the processing. In addition, after the frame is completed by conventional methods, its weight is extremely large, and the overall design weight is easily exceeded, which is difficult to adjust. Modification of the frame structure will bring additional costs. Summary of the invention

[0004] In order to solve one of the above-mentioned technical defects, a rail flaw detection frame and a flaw detection vehicle are provided in an embodiment of the present application.

[0005] A first aspect of the present application provides a rail flaw detection frame, comprising:

[0006] The outer frame is composed of several beams, including:

[0007] Two end beam groups are provided, each serving as an end of the frame;

[0008] A middle beam group, located between the two end beam groups and fixedly connected to the end beam groups;

[0009] The end beam group comprises:

[0010] An end side beam is arranged at the side of the end beam group;

[0011] A traction beam fixedly connected to one end of the end side beam away from the middle beam group;

[0012] The middle beam group includes:

[0013] A middle side beam, arranged on the side of the middle beam group, with two ends thereof connected to the two end beam groups respectively;

[0014] The bolster is arranged at the connection between the end beam group and the middle beam group; the ends of the end side beam and the middle side beam are fixedly connected to the bolster.

[0015] Preferably, the bolster is provided with a mounting hole for connecting the bogie side bearing, and the top of the bogie side bearing can be embedded in the mounting hole of the bolster.

[0016] Preferably, it also includes,

[0017] The internal beam group is arranged inside the outer frame, including:

[0018] The end inner beam group is located inside the end beam group; both sides of the end inner beam group are respectively connected to the end side beams;

[0019] A middle inner beam group is located inside the middle beam group; two sides of the middle inner beam group are respectively connected to the middle side beams;

[0020] One end of the end inner beam group and the middle inner beam group that is close to each other is fixedly connected to one of the bolsters respectively.

[0021] Preferably, the end inner beam group includes a plurality of fixedly connected longitudinal beams and transverse beams; and further includes,

[0022] The impact seat is arranged on the traction beam and extends through the traction beam to the end inner beam group.

[0023] Preferably, it also includes,

[0024] A plurality of large cross beams are provided, and both ends of the large cross beams in the length direction are respectively fixedly connected to the middle side beams.

[0025] Preferably, the middle inner beam group includes several groups of support structures composed of longitudinal beams and cross beams, wherein the cross beams are parallel to the large cross beams, and both ends of the cross beams are respectively fixedly connected to the middle side beams, and each support structure is fixedly connected to the large cross beam.

[0026] Preferably, the large crossbeam is a box structure with a rectangular cross section, including a parallel top plate and a bottom plate, and the top plate and the bottom plate are fixedly connected by two side plates; the large crossbeam also includes:

[0030] Preferably, lifting structures are provided at both ends of the bolster in the length direction.

[0031] The second aspect of the present application also provides a flaw detection vehicle, which uses the flaw detection vehicle frame as described above.

[0032] By adopting the rail flaw detection frame provided in the embodiment of the present application, this solution divides the traditional frame into modules. Compared with the processing of the whole frame, the processing of small modules can achieve optimized design and lightweight design. For the processing of modules with relatively small volume, the difficulty is significantly reduced whether it is hoisting, transportation, or personnel processing. As for the loading of the flaw detection system and the installation of other system interfaces, they can also be produced when different modules are prefabricated according to the requirements of the overall design scheme. The frame made of modules in this solution not only ensures that the strength of the vehicle body is not reduced, but also realizes lightweight design through multi-module structural optimization, while reducing material costs. Because the processing difficulty is reduced, the structural strength of the final frame product is more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0043] In the process of realizing the present application, the inventors found that the existing vehicle frame adopts an integrally welded structure during processing. Due to its large size and too many processing positions involved in the overall structure, errors are prone to occur during the manufacturing process.

[0044] For the above questions, see Figure 1 and Figure 2 In an embodiment of the present application, a rail flaw detection frame is provided, including an outer frame of a frame structure composed of a plurality of beam bodies. The outer frame adopts a modular structure, including two end beam groups 1, each serving as one end of the frame, and a middle beam group 2 located between the two end beam groups 1, and the middle beam group 2 is fixedly connected to the end beam groups 1; the outer frame of the frame is formed by three modules including two end beam groups 1 and one middle beam group 2.

[0045] Each end beam group 1 includes an end side beam 11 arranged on the side of the end beam group 1. Two end side beams 11 are arranged in parallel as the side of the end beam group 1. A traction beam 12 is fixedly arranged at one end of the two end side beams 11 away from the middle beam group 2. The middle beam group 2 includes a middle side beam 21 arranged on the side of the middle beam group 2. Two middle side beams 21 are also arranged as the two side edges of the middle beam group 2. A bolster 3 is arranged at the connection between the end beam group 1 and the middle beam group 2. The length direction of the bolster 3 is perpendicular to the length direction of the frame. The ends of the end side beam 11 and the middle side beam 21 are fixedly connected to the bolster 3. With the modular structural design of this scheme, the side beam of the frame forms a three-section design, and the side beam structure on one side of the frame is composed of two end side beams 11 and one middle side beam 21. The three sections of the beam body are connected by the bolster 3, and the traction beam 12 is arranged at both ends of the frame. During processing, the beam body material undergoes a normalizing heat treatment process to ensure that there are no major defects in the steel plate. By processing the beam body in modular sections in this way, the processing difficulty is greatly reduced, because the volume of any module is much smaller than the entire frame, so the processing quality of the local module can be better controlled, and the processed modules are connected at the bolster 3 to complete the overall production of the frame. This method can also process various components of the frame simultaneously during processing, which also significantly improves the processing efficiency.

[0046] Based on the above implementation scheme, see Figure 4The bolster 3 is provided with a mounting hole 31 for connecting the bogie side bearing. Through this structure, the top of the bogie side bearing is extended into the mounting hole 31 of the bolster 3, so that the height of the car body can be lowered when the car body is assembled, thereby improving the stability of the car body during movement.

[0047] On the basis of the above implementation scheme, an internal beam group 4 is arranged inside the outer frame formed by the above implementation scheme, and the internal beam group 4 includes an end internal beam group 41 and a middle internal beam group 42. The end internal beam group 41 is located inside the end beam group 1; both sides of the end internal beam group 41 are respectively connected to the end side beams 11; the middle internal beam group 42 is located inside the middle beam group 2; both sides of the middle internal beam group 42 are respectively connected to the middle side beams 21; the end of the end internal beam group 41 and the middle internal beam group 42 are respectively fixedly connected to a bolster 3. Figure 3 and Figure 5 The end inner beam group 41 and the middle inner beam group 42 adopt a grid-like structure, through which the firmness of the entire frame is enhanced.

[0048] On the basis of the above implementation scheme, the end inner beam group 41 includes a plurality of fixedly connected longitudinal beams and transverse beams; the longitudinal beams are parallel to the end side beams 11, and are provided with a plurality of roots, one end of each longitudinal beam is fixedly connected to the traction beam 12, and a reinforcing plate is provided at the connection between the two. A transverse beam is provided in connection with each longitudinal beam, the transverse beam is perpendicular to the longitudinal beam, and both ends of the transverse beam are fixedly connected to the end side beam 11. The end inner beam group 41 includes an impact seat 7, which is provided on the traction beam 12 and extends through the traction beam 12 to the end inner beam group 41. Part of the structure of the impact seat 7 is located outside the traction beam 12, and is used to withstand the impact from one side of the traction beam 12. The end inner beam group 41 combined with the impact seat 7 can obtain a stronger impact bearing capacity.

[0049] On the basis of the above embodiment, a plurality of large cross beams 5 are further provided on the frame, and the large cross beams 5 are provided inside the middle beam group 2, and the two ends of the large cross beams 5 in the length direction are respectively fixedly connected to the middle side beams 21. Figure 6 The large cross beam 5 is a box structure with a rectangular cross section, including a parallel top plate and a bottom plate, which are fixedly connected by two side plates 51; a reinforcing structure 52 is arranged inside the large cross beam 5, which can be a reinforcing rod, a reinforcing plate or a reinforcing bracket, etc. In this solution, a reinforcing rod is selected, and both ends of the reinforcing rod are fixedly connected to the side plates 51. Because the middle beam group 2 itself is long and located in the middle of the frame, it will also bear the functional components during the later assembly of the vehicle, so a large cross beam 5 is added to the middle beam group 2 to improve the overall firmness and load-bearing capacity of the middle beam group 2.

[0050] Based on the above implementation scheme, see Figure 5The middle inner beam group 42 includes several groups of support structures composed of longitudinal beams and cross beams. The cross beams are parallel to the large cross beam 5. The two ends of the cross beams are fixedly connected to the middle side beams 21 respectively, and each support structure is fixedly connected to the large cross beam 5.

[0051] The middle inner beam group 42 also adopts a three-section structure design, each section is a grid-shaped support structure, and two large cross beams 5 are arranged inside the middle beam group 2. The two large cross beams 5 are located between the three sections of the middle inner beam group 42. With any end of the frame as the front end, the three sections of the middle inner beam group 42 are divided into a front section 421, a middle section 422, and a rear section 423. Figure 5 The middle left section is the front section 421, and the structures of the three sections are as follows:

[0052] The front section 421 includes two longitudinal beam groups, front and rear, and the rear longitudinal beam group is close to the middle section 422. Each longitudinal beam group includes two parallel longitudinal beams. The distance between the two longitudinal beams in the front longitudinal beam group is smaller than the distance between the two longitudinal beams in the rear longitudinal beam group. Three long cross beams are arranged in the front section 421. The two ends of the long cross beams are fixedly connected to the middle side beam 21 respectively. Two of the long cross beams are connected to the longitudinal beams of the front longitudinal beam group to form a "well" structure. The other long cross beam is located between the front and rear longitudinal beam groups, and is fixedly connected to the longitudinal beams of the front and rear longitudinal beam groups respectively, and reinforcing plates are arranged at the connection points. A number of short cross beams are arranged in the area corresponding to the rear longitudinal beam group. The short cross beams are located between the longitudinal beams of the rear longitudinal beam group and the middle side beam 21, and are fixedly connected to the sides of the two respectively.

[0053] The middle section 422 includes two parallel longitudinal beams, and a short cross beam is arranged between the ends of the two longitudinal beams close to the front section 421. The middle section 422 also includes three long cross beams, and the two ends of the three long cross beams are respectively fixedly connected to the two middle side beams 21. The long cross beam is also fixedly connected to the two longitudinal beams of the middle section 422.

[0054] The rear section 423 is also provided with two parallel longitudinal beams and three long cross beams, and its structure is similar to that of the middle section 422. The difference from the middle section 422 is that the longitudinal beams of the rear section 423 are provided with a plurality of short cross beams away from the middle section 422, and the short cross beams are located between two longitudinal beams.

[0055] The three sections adopt different structural designs, which can be optimized according to the load-bearing requirements of different functional components, thus meeting the load-bearing requirements and reducing the overall weight of the frame.

[0056] Based on the above implementation scheme, see Figure 7, a plurality of grid structures are formed in the space surrounded by the internal beam group 4, and the floor 6 is embedded in the grid structure, and the floor 6 is set in different sizes corresponding to the grid. With this setting method, the floor 6 is directly embedded with the beam group structure, which can shield the beam group structure on the one hand, and on the other hand, there is no need to lay a positive floor on the supporting structure formed by the beam group, which can reduce the weight of the frame after it is manufactured to a certain extent.

[0057] On the basis of the above embodiment, lifting structures are provided at both ends of the length direction of the bolster 3. Considering the transportation and later processing after the frame is manufactured, the lifting structures are reserved, which can be lifting rings, hooks, etc.

[0058] The embodiment of the present application also provides a flaw detection vehicle, which uses the flaw detection vehicle frame as mentioned above.
