Guard rails are also provided at the edges of the work platform 22.
In this embodiment, after the lifting workbench 2 drives the operator or the maintenance device to lift, the center of gravity of the whole maintenance vehicle inevitably moves upwards. At this time, in order to ensure stability of the maintenance vehicle, the vehicle body 1 is provided with a vehicle body fixing device 3 and an auxiliary fixing device 4 in the present embodiment. The automobile body fixing device 3 and the auxiliary fixing device 4 cooperate to fix the automobile body 1, so that the automobile body 1 is stable, and the situations of toppling, side turning and the like of the automobile body 1 caused by upward movement of the gravity center are avoided.
The vehicle body fixing device 3 in this embodiment is preferably provided with four, which are mounted in a rectangular distribution at four symmetrical positions on the side of the vehicle body 1. The four vehicle body fixtures 3 may be connected to the rails 5 on both sides, respectively, so that the four positions of the vehicle body 1 as a whole are connected to the rails 5. Because the track 5 is fixedly arranged on the ground, after the vehicle body 1 is connected with the track 5, the vehicle body 1 is obviously more stable, and the vehicle body 1 cannot fall over or roll over and other problems. The specific structure of the vehicle body fixing device 3 includes a telescopic device 31 and a connecting mechanism 32, and the telescopic device 31 can be a telescopic cylinder or other telescopic devices in the prior art. The telescopic device 31 is specifically fixedly mounted on the rear side of the vehicle body 1, and may be specifically mounted by fasteners or directly welded. The bottom of the telescopic device 31 is fixedly provided with a connecting mechanism 32, and the connecting mechanism 32 is used for being connected with the track 5, so that the vehicle body 1 and the track 5 are connected together. The telescopic 31 operates to drive the connection 32 to the connection with the track 5 or away from the track 5.
As shown in fig. 2 and 3, the connecting mechanism 32 in this embodiment specifically includes a clamping cylinder 322 and two symmetrically arranged clamping arms 321, and the clamping arms 321 are mounted on the bottom of the clamping cylinder 322. When the clamping cylinder 322 is operated, the clamping arms 321 on both sides are brought close to each other, so that the rail 5 is clamped between the two clamping arms 321. When the clamping arms 321 clamp the rail 5, the connecting mechanism 32 is fixedly connected with the rail 5. In this embodiment, the clamping arm 321 is preferably inverted "F", and the inner side thereof includes a first limiting portion and a second limiting portion which are two protrusions disposed up and down. Because track 5 is usually the I-shaped track, and the I-shaped track includes supporting part 51 and track portion, and the arm lock 321 that is the "F" can adapt track portion for track portion is located between first spacing portion and the second spacing portion, and first spacing portion and second spacing portion cooperate constraint track portion jointly, make arm lock 321 can be connected more stable with track 5, can not appear sliding from top to bottom between arm lock 321 and the track 5. Meanwhile, in order to avoid the rail 5 from being damaged due to hard contact between the clip arm 321 and the rail 5, a protective layer is provided on the inner side of the clip arm 321 in the present embodiment, and the protective layer is not shown in the figure. The protective layer may be a silica gel layer, a plastic layer, a rubber layer, or the like, and the protective layer replaces the clip arm 321 to be in direct contact with the track 5, so as to avoid the clip arm 321 from damaging the track 5.
In addition, in order to determine whether the clip arm 321 is in engagement with the rail 5, a detector, which is not shown in the drawing, is fixedly installed on the side of the clip arm 321 by a fastener in the present embodiment. The detector can be a camera or a correlation photoelectric sensor, and is electrically connected with the control terminal which is an industrial control computer. And a worker performs operation and monitoring at the control terminal. The staff at the control terminal confirms whether the clamp arm 321 is matched with the track 5 through the video information fed back by the camera or the feedback information of the correlation sensor, and if the clamp arm 321 is not matched with the track 5, the staff can control the vehicle body fixing device 3 to be matched with the track 5 again.
The working process of the vehicle body fixing device 3 in this embodiment is as follows: the vehicle body 1 is stopped at a position where the tunnel 6 needs maintenance. The telescopic cylinder then drives the link mechanism 32 downward. Since the vehicle body fixing device 3 is located right above the rail 5, the telescopic cylinder moves down, and the connecting mechanism 32 can accurately reach the rail 5. When the telescopic cylinder descends to the lowest end, the clamping cylinders 322 drive the clamping arms 321 on two sides to approach each other, so that the track 5 is clamped between the clamping arms 321, and the connecting mechanism 32 is fixedly connected with the track 5. After the maintenance work is completed, the clamping air cylinders 322 drive the clamping arms 321 on two sides to be away from each other, the clamping arms 321 are separated from the track 5, and then the telescopic air cylinders drive the clamping arms 321 to be away from the track 5.
As shown in fig. 4 and 5, the auxiliary fixing devices 4 in the present embodiment are disposed on the left and right side surfaces of the vehicle body 1, and the auxiliary fixing devices 4 can support the side walls of the tunnel 6, so that the left and right sides of the vehicle body 1 are supported, and the vehicle body 1 is more stable. The structure of the auxiliary fixing device 4 specifically comprises a telescopic supporting column 42 and supporting legs 41, wherein the telescopic supporting column 42 is a telescopic cylinder, one end of the telescopic cylinder is fixedly arranged on the side face of the vehicle body 1, the telescopic cylinder can be specifically connected through a fastener, and the supporting legs 41 are fixedly welded and arranged at the other end of the telescopic cylinder. The support leg 41 is particularly rectangular plate-shaped. When the telescopic cylinder extends out, the telescopic cylinder drives the supporting leg 41 to move transversely, so that the supporting leg 41 is in contact with the inner wall of the tunnel 6. When the auxiliary fixing devices 4 on two sides are in contact with the inner wall of the tunnel 6 through the supporting feet 41, the two sides of the vehicle body 1 are supported, and the vehicle body 1 is prevented from toppling over and turning on one's side. Meanwhile, in order to avoid the supporting leg 41 damaging the inner wall of the tunnel 6 and to avoid the sliding of the supporting leg 41, in this embodiment, a plastic protection component is further disposed on the surface of the supporting leg 41, and the plastic protection component contacts with the inner wall of the tunnel 6, so that the supporting leg 41 is connected with the inner wall of the tunnel 6 more stably.
In order to ensure that the maintenance vehicle works normally in this embodiment, a plurality of lighting devices are further arranged at the top of the vehicle body 1 in this embodiment, and the lighting devices are used for lighting the tunnel 6, so that an operator can conveniently complete maintenance work. The lighting device in this embodiment is preferably a shadowless lamp device, so as to reduce the influence of shadows on operators. Meanwhile, in order to facilitate the operator to check the lower part of the tunnel 6, an illumination lamp belt is further provided around the side surface of the vehicle body 1 in this embodiment, and illuminates the lower part of the tunnel 6.
Example 2
This example was modified on the basis of example 1. As shown in fig. 6 and 7, since the vehicle body 1 is not completely in a horizontal state, the vehicle body 1 may be inclined to some extent. In order to ensure that the clamping arm 321 can be connected to the rail more tightly, the clamping arm 321 in the inverted "F" shape in embodiment 1 has a problem that it cannot be matched with the rail. Therefore, the clamping arm 321 in this embodiment includes a first limiting portion 321a and a second limiting portion 321b, and the first limiting portion 321a is disposed above the second limiting portion 321 b. The first limiting portion 321a is rotatably disposed through a rotation shaft. The first limiting portion 321a is provided with a power cylinder 321c. One end of the power cylinder 321c is rotatably connected to the main body of the clamping arm 321 through a rotating shaft, and the other end of the power cylinder 321c is rotatably connected to the first limiting part 321a through a rotating shaft. The power cylinder 321c can drive the first limiting portion 321a to rotate, so that the first limiting portion 321a is close to or far from the top of the track.
Therefore, in this embodiment, the power cylinder 321c is in a contracted state before the clamp arm 321 is required to be engaged with the rail. After that, the second limiting portion 321b of the clamping arm 321 is matched with the track. The power cylinder 321c extends out to drive the first limiting part 321a to rotate, so that the first limiting part 321a is close to the track. The first limiting portion 321a and the second limiting portion 321b are matched and stably connected with the track.
Meanwhile, after the clamping arm 321 is matched with the rail, the vehicle body can deviate due to working, and at the moment, the clamping arm 321 is very easy to clamp with the rail, so that the clamping arm 321 cannot be separated from the rail. Therefore, in this embodiment, the first protrusion may be further driven by the power cylinder 321c to be away from the track, so as to ensure that the clamping arm 321 can be quickly separated from the track, and avoid the clamping arm 321 from being blocked with the track.
In addition, in this embodiment, a flexible structure 33 may be disposed above the clamping cylinder 322, as shown in fig. 8 and 9, where the clamping cylinder 322 is fixedly installed at the bottom of the flexible structure 33, and the top of the flexible structure 33 is fixedly connected to the telescopic device 31. The flexible structure 33 specifically includes a first movable member 331 and a second movable member 332, with the first movable member 331 disposed above the second movable member 332. The bottom of the first movable part 331 is provided with a movable cavity, and a rotating shaft is fixedly arranged in the movable cavity. The top of the second movable member 332 is located in the movable cavity, and the top of the second movable member 332 is provided with a shaft hole. The rotating shaft is fitted into the shaft hole, so that the first movable member 331 and the second movable member 332 are in a rotationally fitted connection. The first movable member 331 and the second movable member 332 are rotatable about the rotation axis. And the top of the second movable member 332 is in an inverted V shape, so as to limit the rotation angle of the second movable member 332. The rotation angle of the first movable member 331 and the second movable member 332 in this embodiment is preferably limited to 1-5 °, and of course, the angle can be adjusted by changing the inclination of the top surface of the second movable member 332. The second movable member 332 is fixedly connected to the clamping cylinder 322, and the first movable member 331 is fixedly connected to the telescopic device 31. Therefore, when the vehicle body is swayed, the second movable member 332 can rotate 1-5 ° in the movable cavity, so that the connection mechanism 32 is prevented from rubbing against the rail due to swaying, and rail damage is avoided. Meanwhile, the second movable member 332 and the first movable member 331 can rotate, so that the probability of the clamping arm 321 and the rail in the connecting mechanism 32 being blocked is reduced.
Example 3
This embodiment differs from embodiment 1 in that: the connection mechanism 32 in this embodiment is an electromagnet device, and the electromagnet device is mounted at the bottom end of the telescopic cylinder. When the telescopic cylinder is extended, the electromagnet device is in contact with the upper surface of the rail 5. Then the electromagnet device is controlled to work manually or automatically through a controller, and magnetism generated by the electromagnet device is attracted with the track 5, so that the vehicle body 1 is connected with the track 5.
Example 4
The embodiment provides a track maintenance method, as shown in fig. 10, comprising the following steps,
In step one, the vehicle body 1 is moved along the track 5 such that the vehicle body 1 is moved below the position where the tunnel 6 needs to be serviced.
And step two, after the vehicle body 1 reaches the position to be overhauled, the vehicle body fixing device 3 is connected with the track 5, so that the vehicle body 1 is connected with the track 5. Since the rail 5 is fixedly installed on the ground, the vehicle body 1 is maintained in a stable state after the vehicle body 1 is connected to the rail 5.
When the vehicle body fixing device 3 is connected with the rail 5, the auxiliary fixing device 4 starts working again. The auxiliary fixing device 4 is extended out to contact with the inner wall of the tunnel 6, and the auxiliary fixing device 4 enables the left side and the right side of the vehicle body 1 to be supported, so that the vehicle body 1 is further fixed, and the vehicle body 1 is more stable.
Step three, after the car body 1 is fixed and stabilized by the car body fixing device 3 and the auxiliary fixing device 4, the lifting workbench 2 is lifted, and an operator or an overhauling device can reach a position to be overhauled to overhaul the inner wall of the tunnel 6.
