Description

Technical Field

[0001] This application relates to railway maintenance technology, and more particularly to a railway construction operation platform and a railway construction operation vehicle. Background Technology

[0002] After a railway line is put into operation, it requires regular inspection and maintenance, especially the maintenance of railway tunnels. Using various railway maintenance vehicles can significantly improve work efficiency and reduce labor intensity. However, for maintenance work in the central area of ​​railway tunnels, within a range of 1.1 to 2.3 meters from the rail surface, the main method relies on erecting temporary scaffolding on the maintenance vehicle. This requires manual pre-erection of the scaffolding, followed by manual dismantling after construction, resulting in low efficiency and a large workload. Furthermore, the working space created by the scaffolding is currently quite narrow, allowing maintenance work only to one side of the vehicle. Before working on the other side, the scaffolding must be erected again, further reducing efficiency. Summary of the Invention

[0003] To address one of the aforementioned technical deficiencies, this application provides a railway construction operation platform and a railway construction operation vehicle.

[0004] According to a first aspect of the embodiments of this application, a railway construction operation platform is provided, comprising:

[0005] Fixed platform;

[0006] The activity platform can be stored below the fixed platform, or moved in the first direction to one side of the fixed platform, or in the second direction to the other side of the fixed platform;

[0007] Two sets of protective devices are respectively installed on a fixed platform;

[0008] When the platform moves in the first direction, it causes a set of protective devices to deploy and surround the platform; when the platform moves in the second direction, it causes another set of protective devices to deploy and surround the platform.

[0009] According to a second aspect of the embodiments of this application, a railway construction operation vehicle is provided, including: the railway construction operation platform as described above.

[0010] The technical solution provided in this application adopts a fixed platform and a movable platform. The movable platform can be stored under the fixed platform, or moved in a first direction to one side of the fixed platform, or in a second direction to the other side of the fixed platform. Two sets of protective devices are respectively set on the fixed platform. When the movable platform moves in the first direction, it drives one set of protective devices to unfold and surround the perimeter of the movable platform. When the movable platform moves in the second direction, it drives the other set of protective devices to unfold and surround the perimeter of the movable platform. This enables maintenance work to be carried out on both sides of the platform by moving the movable platform left and right. It has high flexibility and is more efficient and safer than the traditional method that requires the construction of a support frame. Attached Figure Description

Detailed Implementation

[0018] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0019] This embodiment provides a railway construction operation platform capable of maintaining railway lines, especially inspecting and maintaining railway tunnels. The platform can be mounted on a railway construction vehicle, specifically on the vehicle's frame. The vehicle travels to the target maintenance location via a running gear at the bottom of the frame, and then the platform is used to perform the maintenance work.

[0020] like Figure 1 As shown, the railway construction operation platform provided in this embodiment includes: a fixed platform 1, a movable platform 2, and a protective device 3. The fixed platform 1 can be fixed to the frame of the work vehicle and remains stationary during maintenance.

[0021] The mobile platform 2 is movable and can be stored under the fixed platform 1, or moved in a first direction to one side of the fixed platform 1, or in a second direction to the other side of the fixed platform 1. Both the first and second directions are the width directions of the work vehicle, and they are opposite to each other. Figure 1 For example, assuming moving in the first direction is moving left and moving in the second direction is moving right, the movable platform 2 can move left to the left side of the fixed platform 1 and unfold, allowing the operator to stand on the movable platform 2 to inspect and maintain the components on the left. The movable platform 2 can also move right to the right side of the fixed platform 1 and unfold, allowing the operator to stand on the movable platform 2 to inspect and maintain the components on the right. Alternatively, the movable platform 2 can be moved to a position below the fixed platform 1 and folded up.

[0022] Two sets of protective devices 3 are respectively installed on the fixed platform 1. Figure 1 A set of protective devices 3 is provided on the left and right sides of the fixed platform 1. The protective device 3 on the left can be unfolded to the left or retracted to the right; the protective device 3 on the right can be unfolded to the right or retracted to the left.

[0023] When the movable platform 2 moves in the first direction, it causes a set of protective devices 3 to deploy and surround the perimeter of the movable platform 2. When the movable platform 2 moves in the second direction, it causes another set of protective devices 3 to deploy and surround the perimeter of the movable platform 2. For example, when the movable platform 2 moves to the left, the protective devices 3 on the left side deploy; when the movable platform 2 moves to the right, the protective devices 3 on the right side deploy. The protective devices 3 have a certain height and surround the perimeter of the movable platform 2 to protect the operator and prevent the operator from falling from the platform.

[0024] The operation of the aforementioned work platform is as follows: The work vehicle enters the tunnel and reaches the target maintenance position. If maintenance is required on the components on the left side of the work vehicle, the movable platform 2 is moved to the left, which in turn moves the left-side protective device 3 to the left. After the platform is in position, the operator can walk from the fixed platform 1 onto the movable platform 2 to perform the maintenance work. After the maintenance on the left side is completed, the operator returns to the fixed platform 1, and then the movable platform 2 is moved to the right until it is below the fixed platform 1, retracting the left-side protective device 3.

[0025] If maintenance is required on the components on the right side of the work vehicle, move the movable platform 2 to the right, which will also move the right-side protective device 3 to the right. After the platform is in position, the operator can walk from the fixed platform 1 onto the movable platform 2 to perform the maintenance work. After the maintenance on the right side is completed, the operator returns to the fixed platform 1, and then moves the movable platform 2 to the left until it is below the fixed platform 1, which will also retract the right-side protective device 3.

[0026] When maintenance is completed at the current location, the mobile platform 2 is moved to the left or right back below the fixed platform 1, and the work vehicle is moved to the next location that needs maintenance or leaves the tunnel.

[0027] The technical solution provided in this embodiment employs a fixed platform and a movable platform. The movable platform can be stored below the fixed platform, or moved in a first direction to one side of the fixed platform, or in a second direction to the other side of the fixed platform. Two sets of protective devices are respectively installed on the fixed platform. When the movable platform moves in the first direction, it causes one set of protective devices to unfold and surround the perimeter of the movable platform. When the movable platform moves in the second direction, it causes the other set of protective devices to unfold and surround the perimeter of the movable platform. This enables maintenance work to be carried out on both sides of the platform by moving the movable platform left and right, which has high flexibility and higher efficiency and safety compared with the traditional method that requires the construction of a support frame.

[0028] Based on the above technical solutions, such as Figure 2 As shown, the protective device 3 includes a main railing 31 and movable railing assemblies 32. The protective surface formed by the main railing 31 is perpendicular to the first direction. Each end of the main railing 31 has a movable railing assembly 32, which can extend and retract along the first direction. The main railing 31 and the movable railing assemblies 32 at both ends surround the movable platform 2 on three sides to protect the operators on the movable platform 2. One end of the movable railing assembly 32 is fixed to the fixed platform 1.

[0029] This embodiment provides an implementation method: the movable railing assembly 32 includes at least two movable railings 321. One movable railing 321 is connected to the fixed platform 1, and the other movable railing 321 is connected to the main railing 31; a guide mechanism is provided between the movable railings 321 to allow relative movement along a first direction via the guide mechanism.

[0030] In this embodiment, four movable railings 321 are used. The four movable railings 321 are connected sequentially by a guide mechanism. The outer movable railing 321 is connected to the fixed platform 1, and the inner movable railing 321 is connected to the movable platform 2. During the unfolding process, the movable platform 2 moves to the left, first moving the movable railing 321 connected to the movable platform 2. When the movable railing 321 moves to its limit, it moves the next movable railing 321, until all movable railings 321 move to their limit positions, so that the movable platform 2 is fully unfolded.

[0031] The protective device 3 on the right is the same as the protective device 3 on the left, but the direction of movement is opposite to that of the protective device 3 on the left. The specific method will not be described in this embodiment.

[0032] The guiding mechanism provided between the adjacent movable railings 321 can be a slider and rail, a slider and groove, a pulley and groove, etc. For example, a groove is provided on one movable railing 321, and a slider is provided on another movable railing 321. The groove extends along a first direction, and the slider is embedded in the groove and moves along the groove, thereby driving and guiding the movement between the adjacent movable railings 321.

[0033] The main railing 31 is composed of multiple horizontal and vertical bars connected together. The height of the main railing 31 can be set according to the average height of an adult, for example, the height of the main railing 31 can be set to 1.2 meters.

[0034] Based on the above technical solution, a protective drive mechanism can also be adopted, which is set at the bottom of the fixed platform 1. The protective drive mechanism is used to drive the movable platform 2 to move in a first direction or in a second direction. The protective drive mechanism can be hydraulically powered, pneumatically powered, or electrically driven. Taking hydraulic power as an example, the protective drive mechanism includes a hydraulic cylinder 41 and a piston rod 42. The hydraulic cylinder 41 is set at the bottom of the fixed platform 1, and the piston rod 42 is connected to the bottom end of the main railing 31.

[0035] In practice, there are two protective drive mechanisms: one for driving the left movable platform 2 to move, and the other for driving the right movable platform 2 to move. Figure 1 In the middle, the protective device 3 on the left is in the deployed state, and a hydraulic cylinder 41 is located below the fixed platform 1, with the hydraulic cylinder 41 being shielded by the fixed platform 1. Figure 1 Only the piston rod 42 extending from the protective drive mechanism is shown. The protective device 3 on the right is in the retracted state, with the piston rod 42 retracted into the hydraulic cylinder 41. Figure 1 Only the hydraulic cylinder 41 in another protective drive mechanism is shown.

[0036] One embodiment is as follows: drive connection parts 311 are provided at both ends of the main railing 31 for connecting to the piston rod 42, for example, by bolts.

[0037] Regarding the connection method between the activity platform 2 and the protective device 3, this embodiment also provides an implementation method: such as... Figure 3 As shown, the movable platform 2 has an insertion hole 21 on its side facing the main railing 31. The bottom of the main railing 31 has a protrusion 312 that can be inserted into the insertion hole 21. The upper surface of the movable platform 2 also has a locking hole 23 communicating with the insertion hole 21. A locking element can be inserted into the locking hole 23 and locked with the protrusion 312, thus achieving a fixed connection between the movable platform 2 and the protective device 3. The locking element can be a pin or a bolt.

[0038] In this embodiment, there are three sockets 21, spaced apart on the movable platform 2. Three corresponding protrusions 312 are also provided.

[0039] When maintenance is required on the left side of the tunnel, insert the locking device into the locking hole 23 to connect the movable platform 2 with the left-side protective device, and then drive the movable platform 2 to move to the left via the protective drive mechanism. After the maintenance on the left side is completed and the movable platform 2 has moved below the fixed platform 1, remove the locking device between the movable platform 2 and the left-side protective device.

[0040] When maintenance is required on the right side of the tunnel, insert the locking device into the locking hole 23 to connect the movable platform 2 with the protective device on the right side, and then drive the movable platform 2 to move to the right through the protective drive mechanism. After the maintenance on the right side is completed and the movable platform 2 has moved below the fixed platform 1, remove the locking device between the movable platform 2 and the protective device on the right side.

[0041] Furthermore, such as Figure 3 and Figure 4 As shown, the movable platform 2 has guide wheels 22 on its side facing the movable railing assembly 32, which can roll along the guide rail 11 on the fixed platform 1, making the relative movement between the movable platform 2 and the fixed platform 1 smoother. Figure 3 As shown, the movable platform 2 has six guide wheels 22 on its side, so that the movable platform 2 can be supported and guided by the fixed platform 1 when moving left or right, and the movable platform 2 will not detach from the fixed platform 1 when it moves to its extreme position. Figure 4 As shown, two guide rails 11 are provided on the lower surface of the fixed platform 1, which cooperate with the guide wheels 22 on both sides of the movable platform 2 respectively, and the guide wheels 22 travel along the guide rails 11.

[0042] Based on the above technical solutions, this embodiment also provides a railway construction work vehicle, including: the railway construction work platform provided in any of the above-mentioned contents. The railway construction work vehicle includes a frame and a running system under the frame, with the work platform mounted on the frame. The work vehicle provided in this embodiment has the same technical effects as the work platform described above.
