Description

Technical Field

[0001] The utility model relates to the technical field of train construction, in particular to a support operation protection platform. Background Technique

[0002] When the whole train of the multiple unit train is jacked up for construction, the whole train of the vehicle is lifted to the required height. In some scenarios, the track is used as a support for personnel to climb for work. According to GB / T 2585-2007, the current gauge between the two elevated tracks (about 1000 mm from the ground) of the multiple unit train is 1430 mm, and the inner width of the vehicle is about 3200 mm. The following difficulties exist in the construction work:

[0003] (1) The distance between the edge of the vehicle width and the track is about (3200 - 1430) / 2 ≈ 885 mm. Only relying on the track support, the arm span of the construction workers is insufficient or the construction intensity is too high to meet the long-term operation requirements, and the installation of the turning plate is not firmly locked.

[0004] (2) When the construction workers climb for work, they are suspended between the two tracks, and there are safety risks during the construction process.

[0005] (3) For example, when carrying out construction work in the bogie area, it is necessary to first separate the bogie (located at the end of the vehicle) from the vehicle body and then shift it to avoid this area to meet the construction space requirements. One of the shifting schemes is: the vehicle is lifted as a whole by the car lifter, and the bogie is successively pushed along the track to be stored under the equipment compartment in the middle of the vehicle; in this scheme, because there is a bogie stored in the middle of the vehicle, the vehicle cannot fall back, and it is necessary for personnel to climb for work with the help of an auxiliary operation protection platform. However, due to being too close to the car lifter, the space of the traditional climbing ladder or platform does not meet the placement requirements. Summary of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a support operation protection platform, which can move or be locked along the track, can meet the dead-angle-free construction work in the vehicle width direction, can be flexibly combined and switched according to the construction work scope, realizes the storage of the bogie without changing the track and shifting, and effectively improves the operation efficiency of the whole train jacking operation of the vehicle.

[0007] In order to achieve the above purpose, the utility model is realized by the following technical solutions:

The second section is rotatably connected to one end of the first section, and the third section is rotatably connected to the other end of the first section; the second section and the third section can be turned over to form a horizontal plane with the first section or be attached to the first section.

[0009] As a further implementation method, guardrails are detachably installed on the outer sides of the second section and the third section.

[0010] As a further implementation method, when the second section and the third section form a horizontal plane with the first section, the guardrails are perpendicular to the horizontal plane.

[0011] As a further implementation method, the guardrails are connected to the second section and the third section through a plug-and-play structure.

[0012] As a further implementation method, the outer sides of the relatively arranged guardrails are connected through a protective rope.

[0013] As a further implementation method, the length of the second section is equal to the length of the third section, and the length of the first section is greater than the lengths of the second section and the third section.

[0014] As a further implementation method, the bottom surface of the first section is installed on the track wing surface through a locking and fixing structure.

[0028] Example 1:

[0029] In order to make the purpose, technical solutions and advantages of the utility model clearer, the embodiments of the utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This embodiment provides a support operation protection platform for the operation condition where the vehicle is lifted integrally by a car lifter and the bogie is successively pushed under the equipment cabin in the middle of the vehicle along the track, reducing the extra waste caused by the bogie moving out of the track or being stored in the depot, and reducing the secondary vehicle height fallback operation, which is suitable for the rapid abnormal handling operation of the elevated rail production line.

[0031] As Figures 1-4 shown, the support operation protection platform laid on the track in this embodiment includes at least one support unit, and the number of support units is determined according to the operation requirements and the size of the plate; for example, the width of a single support unit is 700 mm, and they can be connected and used according to the construction operation range. When multiple support units are provided, the multiple support units are successively arranged along the length direction of the track 4 to form an operation area.

[0032] The support unit adopts a three-section structure, including the first section 1, the second section 2 and the third section 3, where the first section 1 is used as the middle section and is installed on the upper side of the track 4; the second section 2 and the third section 3 are symmetrically installed on both sides of the first section 1, and both the second section 2 and the third section 3 can be flipped relative to the first section 1.

[0033] In this embodiment, the second section 2 and the third section 3 are respectively rotatably connected to the first section 1 through the door leaf 11, and both the second section 2 and the third section 3 can be flipped 180°; as Figure 3 shown, in the use state, the second section 2 and the third section 3 are flipped outwards to be on the same horizontal plane as the first section 1; when not in use, the second section 2 and the third section 3 are flipped inwards to fit against the upper surface of the first section 1, that is, in the folded state, saving space.

[0034] The length of the second section 2 is equal to the length of the third section 3, and the length of the first section 1 is greater than the lengths of the second section 2 and the third section 3. This is because the first section 1 needs to have enough length to be assembled on the upper side of the track 4, and the length of the first section 1 satisfies that after the first section 1 is installed on the upper side of the track 4, the end of the first section 1 extends beyond the track 4 by a certain length; the second section 2 and the third section 3 form a cantilever structure. The length is considered for the actual installation space, and secondly, there is no support at its bottom, and being too long is likely to cause unstable structural support.

[0035] As Figure 4 shown, the first section 1 is installed on the upper sides of two tracks 4, and the tracks 4 are connected to the first section 1 through a locking and fixing structure. Loosening the locking and fixing structure can adjust the installation position of the support unit; the locking and fixing structure, as a connecting component, can be set in a structural form according to actual requirements.

[0036] In this embodiment, the locking and fixing structure at least includes a locking plate member 7 and a connecting member 8. The locking plate member 7 is used to clamp the wing surface of the track 4, and then the locking plate member 7 is connected to the first section 1 of the support unit through the connecting member 8; a plurality of connecting members 8 are provided to make the protective platform firmly fixed to the track 4.

[0037] In order to avoid drilling holes in the bottom surface of the protective platform, a fixing seat 9 can also be provided. The fixing seat 9 is installed on the bottom surface of the first section 1, and the connecting member 8 passes through the locking plate member 7 and is connected to the fixing seat 9.

[0038] Among them, the locking plate member 7 can be a U-shaped plate, a rectangular plate or other forms, the connecting member 8 is a bolt, and the fixing seat 9 is welded in a U-shape to the bottom surface of the first section 1.

[0039] The protective platform further includes a guardrail 5. The guardrail 5 is installed at both ends of each support unit, and the guardrail 5 is detachably connected to the first section 1 and the third section 3 of the support unit. The guardrail 5 is removed when folding the protective platform.

[0040] As Figure 1 、 Figure 2 and Figure 4 shown, the guardrail 5 of this embodiment is connected to the outer end surfaces of the second section 2 and the third section 3 through a plug-in structure; the plug-in structure includes a plug pin 10, and the plug pin 10 passes through the guardrail 5 and is connected to the support unit.

[0041] In this embodiment, the guardrail 5 is made of round tubes, and its main body is an inverted U-shaped structure. To enhance the protective performance, connecting rods are installed at corresponding heights of the U-shaped main body. The connecting rods can be one or more, specifically determined according to the height of the guardrail 5. The ends of the U-shaped main body are connected to the support unit through pins 10.

[0042] Since the guardrail 5 is installed at both ends of the support unit, it serves as a protection on both sides of the platform; for the other two sides of the protection platform, safety ropes are provided, and both ends of the safety ropes are connected to the corresponding guardrails 5, so as to protect the entire working area through the cooperation of the guardrails 5 and the safety ropes.

[0043] The protection platform in this embodiment adopts a three-section structure. The first section 1 is laid on the upper side of the track 4 and fixed to the wing surface of the track 4 through a locking and fixing structure, which facilitates the locking or loosening of the protection platform and the track 4, and the installation position of the protection platform along the track 4 is adjustable. The second section 2 and the third section 3 are door leaf flap structures. During construction operations, the second section 2 and the third section 3 are horizontally rotated 180 degrees to be horizontal with the first section 1; when there is no need for operations on both sides, the door leaf flap structures can be flipped to fit the upper surface of the first section 1.

[0044] This embodiment makes full use of the sectional structure dimensions of the existing elevated rail track 4 for design. The locking and fixing method does not damage the rail surface, the fixing method is simple, the protection method is effective, and the folding structure of the door leaf 11 is reliable, which can meet the dead-free construction operations in the vehicle width direction, avoid the disadvantages of limited space for the whole train car-lifting machine and high labor intensity of construction workers; at the same time, it can be flexibly combined and switched according to the construction operation range, and can realize the storage of bogies without changing the track and shifting positions, effectively improving the operation efficiency of the whole train car-lifting operation.

[0045] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
