Description

Technical Field

[0001] This utility model relates to the technical field of railway vehicle parts, specifically a high load-bearing strength railway vehicle lifting seat device. Background Technology

[0002] Lifting support devices are mainly used in railway vehicle lifting operations to support the tensile strength of the vehicles and ensure the safety of vehicle handling. With the development of railway vehicles, the load-bearing capacity of railway vehicles is increasing, and similarly, the load-bearing capacity of lifting support devices is also increasing.

[0003] Application No. 201521050429.8 discloses a lifting seat device and a railway vehicle equipped with the device. The device includes a base plate, a lifting lug perpendicular to the base plate, and baffles of a folded shape, securely connected to the base plate on both sides of the lifting lug. The railway vehicle includes multiple lifting seat devices mounted on the side beams of the railway vehicle. This invention provides sufficient tensile strength and ensures safety during vehicle handling because it features a lifting lug perpendicular to the base plate and baffles securely connected to the base plate on both sides of the lug. The lifting lug has a rectangular shape at one end and is securely connected to the base plate, while the other end is rounded, reducing stress concentration during operation. Furthermore, the thickened reinforcing plate securely connected to each baffle and the base plate effectively improves the load-bearing capacity and extends the service life of the device.

[0004] The technical solution mainly fixes the lifting seat device to the side beam by welding. However, only the edge position can be welded, resulting in a small connection surface of the structure, which in turn reduces the connection strength of the structure and affects the load-bearing capacity. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high load-bearing strength railway vehicle lifting seat device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high load-bearing strength railway vehicle lifting seat device, including a base plate, support bars fixed on both sides of the base plate, through holes opened on both sides of the bottom of the base plate, a support plate fixed on the top of the base plate, and inclined bracing plates connected to both sides of the outer surface of the support plate.

[0007] By adopting the above technical solution, firstly, the workers contact the bottom plate and support strips with the bottom of the railway vehicle, and then contact the support plate with the side of the railway vehicle. Next, the workers weld the bottom plate, support strips, and support plate together with the railway vehicle. During this process, the addition of support strips and through holes increases the welding area between the lifting seat device and the railway vehicle, thereby improving the welding strength and enabling the lifting seat device to be installed more stably, thus increasing its load-bearing capacity. When the lifting equipment lifts the main body of the lifting seat, the outer surface of the bottom plate will be subjected to an upward force. At this time, the outer surface area of ​​the bottom plate, through the diagonal bracing plate and the support plate, transmits the force to the side wall of the railway vehicle, thus providing support and improving the load-bearing capacity.

[0008] Furthermore, multiple support bars are provided, and the multiple support bars are symmetrically distributed.

[0009] By adopting the above technical solution, the workers will make the base plate and support strips contact the bottom of the railway vehicle and make the support plate contact the side of the railway vehicle. Then, the workers will weld the base plate, support strips and support plate together with the railway vehicle.

[0010] Furthermore, the support plate is perpendicular to the base plate, and the diagonal bracing plate is triangular.

[0011] By adopting the above technical solution, when the lifting equipment lifts the main body of the base plate, the outer surface of the base plate will be subjected to an upward force. At this time, the outer surface area of ​​the base plate will transfer the force to the side wall of the railway vehicle through the inclined bracing plate and the support plate, thereby achieving a supporting effect and improving the load-bearing strength.

[0012] Furthermore, multiple inclined bracing plates are provided, and the multiple inclined bracing plates are distributed at equal intervals.

[0013] By adopting the above technical solution, the outer surface area of ​​the base plate transmits force to the side wall of the railway vehicle through the inclined bracing plate and the support plate, thereby achieving a supporting effect and improving the load-bearing strength.

[0014] Furthermore, there are two through holes, and the two through holes are symmetrically distributed.

[0015] By adopting the above technical solution, the welding area between the lifting seat device and the railway vehicle is increased through the setting of support bars and through holes, thereby improving the welding strength and enabling the lifting seat device to be installed more stably, thus improving the load-bearing strength.

[0016] Furthermore, both sides of the top of the base plate and the support strip are provided with ramps.

[0017] By adopting the above technical solution, the welding quality between the base plate and the support bar and the railway vehicle is further improved because both sides of the top of the base plate and the support bar are provided with slopes.

[0018] Furthermore, slopes are provided on both sides of the back of the support plate.

[0019] By adopting the above technical solution, the welding quality between the support plate and the railway vehicle is further improved because both sides of the back of the support plate are equipped with slopes.

[0020] Furthermore, a hanging bracket body is connected to the top of the base plate.

[0021] By adopting the above technical solution, workers can connect the steel cable of the lifting equipment to the main body of the lifting platform, which facilitates the lifting of railway vehicles for transportation and maintenance.

[0022] Furthermore, the bottom of the main body of the hanging bracket is provided with a protrusion, and the bottom of the base plate is provided with a connecting plate and a slot respectively.

[0023] By adopting the above technical solution, the workers pass the main body of the hanger through the slot from top to bottom and weld the main body of the hanger to the base plate. Then, the workers put the connecting plate on the bottom protrusion of the hanger main body and weld the connecting plate to the hanger main body and the base plate. This installation method increases the connection surface between the hanger main body and the base plate, improving stability and load-bearing strength.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model increases the welding area between the lifting seat device and the railway vehicle by setting support bars and through holes, thereby improving the welding strength and enabling the lifting seat device to be installed more stably, thus improving the load-bearing strength; the increased welding area also increases the connection strength.

[0026] 2. By setting up a support plate and a diagonal brace, when the lifting equipment lifts the main body of the base, the outer surface of the base plate will be subjected to an upward force. At this time, the outer surface area of ​​the base plate will transfer the force to the side wall of the railway vehicle through the diagonal brace and the support plate, thereby achieving a supporting effect and improving the load-bearing strength. At the same time, the support plate increases the welding area, further improving the load-bearing strength. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] A high load-bearing strength railway vehicle lifting seat device, such as Figures 1-4 As shown, the system includes a base plate 1, with multiple support bars 2 fixed to both sides of the base plate 1. The support bars 2 are symmetrically distributed. Sloping ramps are provided on both sides of the top of the base plate 1 and the support bars 2. Two through holes 3 are provided on both sides of the bottom of the base plate 1, symmetrically distributed. Workers bring the base plate 1 and support bars 2 into contact with the bottom of the railway vehicle and the support plate 4 into contact with the side of the railway vehicle. Then, workers weld the base plate 1, support bars 2, and support plate 4 to the railway vehicle. During this process, the support bars 2 and through holes 3 increase the welding area between the lifting device and the railway vehicle, thereby improving the welding efficiency. The strength allows for more stable installation of the lifting seat device, thereby improving its load-bearing capacity. A support plate 4 is fixed to the top of the base plate 1. Slopes are provided on both sides of the back of the support plate 4. The support plate 4 is perpendicular to the base plate 1. The diagonal bracing plate 5 is triangular. Diagonal bracing plates 5 are connected to both sides of the outer surface of the support plate 4. Multiple diagonal bracing plates 5 are provided and are equidistantly distributed. When the lifting equipment lifts the main body 6 of the lifting seat, the outer surface of the base plate 1 will be subjected to an upward force. At this time, the outer surface area of ​​the base plate 1 transmits the force to the side wall of the railway vehicle through the diagonal bracing plate 5 in conjunction with the support plate 4, thereby achieving a supporting effect and improving the load-bearing capacity. At the same time, the support plate 4 increases the welding area.

[0036] See Figures 1-4 In the above embodiment, the top of the base plate 1 is connected to the lifting body 6, and the lifting equipment can lift the railway vehicle through the lifting body 6.

[0037] Example 2:

[0038] Based on the above embodiment 1, the following settings are made to increase the load-bearing strength of the main body 6 of the hanging seat.

[0039] See Figure 1 , Figure 3 and Figure 4In the above embodiment, the bottom of the hanging bracket body 6 is provided with a protrusion, and the bottom of the base plate 1 is provided with a connecting plate 7 and a slot 8. The worker inserts the hanging bracket body 6 through the slot 8 from top to bottom and welds the hanging bracket body 6 to the base plate 1. Then the worker puts the connecting plate 7 on the bottom protrusion of the hanging bracket body 6 and welds the connecting plate 7 to the hanging bracket body 6 and the base plate 1. This installation method increases the connection surface between the hanging bracket body 6 and the base plate 1, and improves stability and load-bearing strength.

[0040] The implementation principle of this utility model is as follows: First, the workers contact the bottom plate 1 and the support strip 2 with the bottom of the railway vehicle and the support plate 4 with the side of the railway vehicle. Then, the workers weld the bottom plate 1, the support strip 2 and the support plate 4 together with the railway vehicle. During this process, the welding area between the lifting seat device and the railway vehicle is increased by setting the support strip 2 and the through hole 3, thereby improving the welding strength and enabling the lifting seat device to be installed more stably, thereby improving the load-bearing strength.

[0041] Then, the workers inserted the main body 6 of the hanging bracket into the slot 8 from top to bottom and welded the main body 6 of the hanging bracket to the base plate 1. After that, the workers put the connecting plate 7 on the bottom protrusion of the main body 6 of the hanging bracket and welded the connecting plate 7 to the main body 6 of the hanging bracket and the base plate 1. This installation method increases the connection surface between the main body 6 of the hanging bracket and the base plate 1, and improves stability and load-bearing strength.

[0042] When the lifting equipment lifts the main body 6 of the lifting platform, the outer surface of the base plate 1 will be subjected to an upward force. At this time, the outer surface area of ​​the base plate 1 will transfer the force to the side wall of the railway vehicle through the bracing plate 5 and the support plate 4, thereby achieving a supporting effect and improving the load-bearing strength.
