[0018] 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.

[0019] This embodiment provides a railway construction work platform, which can be used for railway line maintenance, especially for railway tunnel inspection and maintenance. The railway construction work platform can be set on a railway construction work vehicle, specifically on the frame of the work vehicle, and the work vehicle is moved to the inspection target position through the running system at the bottom of the frame, and then the inspection and maintenance work is carried out through the work platform.

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

[0021] The movable platform 2 is movable and can be stored under the fixed platform 1, or moved to one side of the fixed platform 1 in a first direction, or moved to the other side of the fixed platform 1 in a second direction. The first direction and the second direction are both width directions of the work vehicle, and the first direction and the second direction are opposite to each other. Figure 1 For example, assuming that moving in the first direction is moving to the left, and moving in the second direction is moving to the right. Then the movable platform 2 can move to the left to the left side of the fixed platform 1 in an unfolded state, and the operator can stand on the movable platform 2 to inspect and maintain the components on the left. The movable platform 2 can also move to the right to the right side of the fixed platform 1 in an unfolded state, and the operator can stand on the movable platform 2 to inspect and maintain the components on the right. Alternatively, the movable platform 2 can also move to the bottom of the fixed platform 1 in a stored state.

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

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

[0024] The use process of the above-mentioned working platform is as follows: the working vehicle drives into the tunnel and reaches the target maintenance position. If the components on the left side of the working vehicle need to be repaired, the movable platform 2 is moved to the left, and the left protective device 3 is driven to move to the left. After moving to the right, the operator can walk from the fixed platform 1 to the movable platform 2 to perform maintenance work. After the left side maintenance is completed, the operator returns to the fixed platform 1, and then moves the movable platform 2 to the right to return to the bottom of the fixed platform 1, and drives the left protective device 3 to retract.

[0025] If the components on the right side of the work vehicle need to be repaired, the movable platform 2 is moved to the right, and the right side protection device 3 is driven to move to the right. After the movement is in place, the operator can walk from the fixed platform 1 to the movable platform 2 to perform the maintenance work. After the right side maintenance is completed, the operator returns to the fixed platform 1, and then moves the movable platform 2 to the left to the bottom of the fixed platform 1, and drives the right side protection device 3 to retract.

[0026] When the inspection is completed at the current position, the movable platform 2 is moved leftward or rightward back to the bottom of the fixed platform 1, and the work vehicle is moved to the next position requiring inspection or leaves the tunnel.

[0027] The technical solution provided in this embodiment adopts a fixed platform and a movable platform. The movable platform can be stored under the fixed platform, or moved to one side of the fixed platform in a first direction, or moved to the other side of the fixed platform in a second direction; two groups of protective devices are respectively arranged on the fixed platform; when the movable platform moves in the first direction, one group of protective devices is driven to unfold and surround the periphery of the movable platform; when the movable platform moves in the second direction, the other group of protective devices is driven to unfold and surround the periphery of the movable platform, so that the movable platform can move left and right to perform maintenance operations on both sides of the platform, which has high flexibility and higher efficiency and safety compared with the traditional method that requires the construction of a bracket.

[0028] Based on the above technical solution, Figure 2 As shown, the protection device 3 includes: a main railing 31 and a movable railing group 32, wherein the protection surface formed by the main railing 31 is perpendicular to the first direction, and a group of movable railing groups 32 are respectively provided at both ends of the main railing 31, and the movable railing group 32 can be extended and retracted along the first direction. The main railing 31 and the movable railing groups 32 at both ends surround the movable platform 2 on three sides to protect the operator on the movable platform 2. One end of the movable railing group 32 is fixed to the fixed platform 1.

[0029] This embodiment provides an implementation method: the movable railing group 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 so as to move relatively in the first direction through the guide mechanism.

[0030] In this embodiment, four movable railings 321 are used. The four movable railings 321 are connected in sequence through a guide mechanism, the movable railing 321 located on the outside is connected to the fixed platform 1, and the movable railing 321 located on the inside is connected to the movable platform 2. During the unfolding process, the movable platform 2 moves to the left, first driving the movable railing 321 connected to the movable platform 2 to move, and when the movable railing 321 moves to the limit, it drives the next movable railing 321 to move, until all the movable railings 321 move to the limit position, so that the movable platform 2 is fully unfolded.

[0031] The protection device 3 on the right is the same as the protection device 3 on the left, and its moving direction is opposite to that of the protection device 3 on the left. The specific method will not be repeated in this embodiment.

[0032] The guide mechanism provided between the adjacent movable rails 321 may be a slider and a slide rail, a slider and a slide groove, a pulley and a slide groove, etc. For example, a slide groove is provided on one movable rail 321, and a slider is provided on another movable rail 321, the slide groove extends along a first direction, and the slider is embedded in the slide groove and moves along the slide groove, so as to realize driving and guiding the movement between the adjacent movable rails 321.

[0033] The main railing 31 includes a plurality of horizontal bars 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 is set to 1.2 meters.

[0034] On the basis of the above technical solution, a protection drive mechanism can also be used, which is arranged at the bottom of the fixed platform 1. The protection drive mechanism is used to drive the movable platform 2 to move in the first direction or in the second direction. The protection drive mechanism can be driven by hydraulic power, pneumatic power or motor power. Taking hydraulic power as an example, the protection drive mechanism includes a hydraulic cylinder body 41 and a piston rod 42. The hydraulic cylinder body 41 is arranged 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 protection drive mechanisms, one for driving the movable platform 2 on the left side to move, and the other for driving the movable platform 2 on the right side to move. Figure 1 In the figure, the left protective device 3 is in the unfolded state, a hydraulic cylinder body 41 is located below the fixed platform 1, and the hydraulic cylinder body 41 is blocked by the fixed platform 1. Figure 1 Only one piston rod 42 extending from the protection drive mechanism is shown. The protection device 3 on the right is in the stowed state, and the piston rod 42 is retracted into the hydraulic cylinder body 41. Figure 1 Only the hydraulic cylinder 41 in the other guard drive mechanism is shown.

[0036] One implementation is: driving connection parts 311 are provided at both ends of the main railing 31 for connecting with the piston rod 42, for example, by bolts.

[0037] Regarding the connection mode between the movable platform 2 and the protective device 3, this embodiment also provides an implementation method: Figure 3 As shown, a plug hole 21 is provided on the side of the movable platform 2 facing the main railing 31. A protrusion 312 that can be inserted into the plug hole 21 is provided at the bottom of the main railing 31. A locking hole 23 connected to the plug hole 21 is also provided on the upper surface of the movable platform 2. A locking member can be inserted into the locking hole 23 and locked with the protrusion 312 to achieve a fixed connection between the movable platform 2 and the protective device 3. The locking member can be a latch or a bolt.

[0038] In this embodiment, there are three plug holes 21, which are arranged at intervals on the movable platform 2. Three protrusions 312 are correspondingly arranged.

[0039] When the left side of the tunnel needs to be inspected, the locking piece is inserted into the lock hole 23 to connect the movable platform 2 with the left side protection device, and then the movable platform 2 is driven to move to the left by the protection drive mechanism. After the left side inspection is completed and the movable platform 2 is moved under the fixed platform 1, the locking piece between the movable platform 2 and the left side protection device is removed.

[0040] When the right side of the tunnel needs to be inspected, the locking piece is inserted into the lock hole 23 to connect the movable platform 2 with the protective device on the right side, and then the movable platform 2 is driven to move to the right by the protective drive mechanism. After the right side inspection is completed and the movable platform 2 is moved under the fixed platform 1, the locking piece between the movable platform 2 and the protective device on the right side is removed.

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