Description

Technical Field

[0001] This utility model relates to a coupler lifting device for high-speed trains, belonging to the technical field of hydraulic lifting devices. Background Technology

[0002] During the installation of couplers on high-speed trains, especially the coupler at the driver's cab end, the installation space is extremely limited due to components such as the opening and closing mechanism and anti-creep devices. There are also no suitable tools to assist the operation. Historically, the only option has been to use a forklift to lift the coupler and slowly insert it into the installation position. Furthermore, aligning the coupler with the mounting holes on the car body is difficult, requiring the forklift to be pulled out and adjusted, often repeatedly. The entire process is time-consuming and labor-intensive. Because of the low adjustment precision of forklifts, not only is the work inefficient, but it also easily causes bumps and damage to vehicle components, leading to greater consequences and making it difficult to guarantee product quality.

[0003] In summary, due to extremely limited space and a lack of corresponding tooling and high-precision equipment, the installation process will result in low efficiency and be time-consuming and labor-intensive. Utility Model Content

[0009] Furthermore, the hydraulic cylinder is a three-stage hydraulic cylinder and is equipped with an explosion-proof device inside.

[0010] Furthermore, a movable component is installed at the bottom end of the horizontal frame; The movable component includes a front caster and a rear caster. The front caster is a fixed heavy-duty caster, and the rear caster is a swivel heavy-duty caster.

[0016] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1 As shown, this embodiment provides a train coupler lifting device, including: a main frame 1; the main frame 1 includes a vertical frame 11 and a horizontal frame 12; a left slide rail 13 and a right slide rail 14 are respectively provided on both sides of the vertical frame 11, and a fence plate 2 is slidably connected between the left slide rail 13 and the right slide rail 14. The fence panel 2 is provided with a fork arm 3 and a longitudinal drive assembly 4 and a transverse drive assembly 5 for driving the fork arm 3. The lateral drive assembly 5 includes a lead screw 51 and a motor 52; the lead screw 51 is connected to the fork arm 3, and the fork arm 3 is driven by the motor 52 to rotate a four-cylinder, thereby causing the fork arm 3 to move laterally relative to the fence plate 2. The longitudinal drive assembly 4 includes a hydraulic cylinder 41 and a traction component 42; both ends of the hydraulic cylinder 41 are connected to the fence panel 2 via the traction component 42. The left slide rail 13 and the right slide rail 14 are arranged symmetrically on both sides of the central axis of the oil cylinder 41.

[0019] In this embodiment, the traction component 42 in the longitudinal drive assembly 4 is selected as a chain. The chain is connected to both ends of the hydraulic cylinder 41, and the other end of the chain is also connected to the fence plate 2. Thus, when the hydraulic cylinder 41 extends, it can drive the chain, thereby driving the fence plate 2 to move.

[0020] Specifically, one side of the fence panel 2 is provided with a left slider 21 and a right slider 22 for connecting to the left slide rail 13 and the right slide rail 14 respectively; the left slider 21 and the right slider 22 are both used to engage the fence panel 2 in the sliding track, thereby ensuring that the fork arm 3 can move stably and accurately when moving vertically.

[0021] Specifically, the lateral drive assembly 5 includes guide rods 53 mounted on the surface of the fence panel 2; the guide rods 53 are configured as two and are respectively arranged on both sides of the lead screw 51; the fork arm 3 includes a plug end 31 and a connecting end 32, the connecting end 32 and the plug end 31 are perpendicular to each other, and the connecting end 32 is connected to the guide rods 53 and the lead screw 51 respectively. The surface of the fence panel 2 is provided with three guide rods, of which the lead screw 51 is located in the middle position. The lead screw 51 is connected to the connecting part of the fork arm 3, and the lead screw 51 is used to drive the fork arm 3 connected to the lead screw 51 to move according to the rotation of the motor 52. The other two guide rods 53 are respectively installed on both sides of the lead screw 51, and are arranged in parallel in this embodiment to ensure stability during lateral movement; the guide rods 53 are also slidably connected to the connecting part of the fork arm 3.

[0022] One point that should be mentioned in this embodiment is that the insertion end 31 of the fork arm 3 can be adjusted according to actual practical needs. Specifically, it can be adjusted by relying on the opening of the connecting part to adjust the separation distance of the fork arm 3.

[0023] In addition, according to actual working conditions, the hydraulic cylinder 41 is a three-stage hydraulic cylinder 41 and is equipped with an explosion-proof device inside. The bottom end of the horizontal frame 12 is equipped with a movable component 6; the movable component 6 includes a front caster 61 and a rear caster 62. In this embodiment, the front caster 61 is a fixed heavy-duty caster, and the rear caster 62 is a swivel heavy-duty caster.

[0024] In actual use, due to the weight of the coupled train coupler, a gantry anti-tilting block 7 is provided at the connection between the vertical frame 11 and the horizontal frame 12 to prevent tilting forward during the coupling process.

[0025] The back of the vertical frame 11 is also provided with a pull-back support rod 8. The pull-back support rod 8 has a circular cross-section and is connected to the upper part, lower part and end of the horizontal frame 12 of the vertical frame 11 respectively.

[0026] The specific usage process is as follows: Adjust the opening of the fork arm 3 to a suitable size according to the dimensions of the coupler itself, so that the coupler can be fixed to the fork arm 3; for example... Figure 2 As shown, the hydraulic station 9 is used to lift the fork arm 3 along the left slide rail 13 and the right slide rail 14 together with the coupler to the designated height. The push device's rear pull-type support rod 8 pushes the coupler to the corresponding vehicle body mounting surface. After inserting the bolts to complete the tightening operation, the coupler lifting device is removed.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
