Abstract
The invention discloses an inspection trolley derailment and falling prevention device which comprises a first stop block, an axial screw, a second stop block, a third stop block, a track, outer trolley body blocks and a mounting bracket, wherein the track is fixedly mounted through the mounting bracket; according to the invention, when the inspection trolley is in derailment risk or wheels are derailed, the design distance is smaller than the width of the track, so that the trolley can be clamped and does not fall off after being actually derailed, and meanwhile, the derailment and falling prevention protection of the inspection trolley can be realized without influencing the normal operation of the trolley.
Description
Technical Field
The invention relates to the technical field of derailment and falling prevention of traction trolleys, in particular to a derailment and falling prevention device of an inspection trolley.
Background
At present, the track of an underground inspection trolley is basically hoisted to pass through an underground top plate riveting rod, and a robot track is hoisted by a riveting cable, so that the inspection trolley can well walk on the track, and meanwhile, the function of the inspection robot is exerted to monitor the underground condition, so that the robot can possibly derail and fall off in the running process of the track, and the danger is easily caused; in view of the defects, the device for preventing the derailment and the falling of the inspection trolley is necessary.
Disclosure of Invention
The invention aims to provide a device for preventing the derailment and falling of an inspection trolley, which can clamp the trolley after the trolley is actually derailed and prevent the trolley from falling because the design distance is smaller than the width of a track when the inspection trolley is derailed or wheels of the inspection trolley are derailed, and can play a role in preventing the derailment and falling of the inspection trolley when the normal operation of the trolley is not influenced.
The purpose of the invention can be realized by the following technical scheme:
patrol and examine dolly anticreep rail device that falls, including first dog, axle position screw, second dog, third dog, track, outer car body block and installing support, the track passes through installing support fixed mounting, track top bilateral symmetry and equidistance are provided with a plurality of outer car body blocks, just track top one side installs first dog on outer car body block, just a second dog end passes through the axle position screw and is connected with first dog rotation, track top opposite side installs the third dog on outer car body block.
As a further scheme of the invention: through holes a are formed in four corners of the first stop block, a rotating hole is formed in the center point of the first stop block, and the shaft position screw is rotatably connected with the rotating hole through a bearing.
As a further scheme of the invention: and through holes b are formed in four corners of the third block.
As a further scheme of the invention: the second stop block is a square strip with semicircular two ends, a through hole c is formed in one end of the second stop block, and the shaft position screw penetrates through the through hole c and the rotating hole in sequence.
The invention has the beneficial effects that: the second stop block can rotate around the axis screw when the trolley runs, so that the second stop block cannot be clamped with the rail mounting bracket when the trolley runs, the normal running of the trolley is not influenced, and meanwhile, the derailing and falling prevention protection of the inspection trolley can be realized.
Drawings
In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is an overall side view of the present invention;
in the figure: 1. a first stopper; 2. an axial screw; 3. a second stopper; 4. a third stopper; 5. a track; 6. an outer car body block; 7. and (7) mounting a bracket.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-2, the derailment and falling prevention device for the inspection trolley comprises a first stop block 1, an axial screw 2, a second stop block 3, a third stop block 4, a rail 5, outer trolley body blocks 6 and a mounting bracket 7, wherein the rail 5 is fixedly mounted through the mounting bracket 7, a plurality of outer trolley body blocks 6 are symmetrically arranged on two sides of the top of the rail 5 at equal intervals, the first stop block 1 is mounted on the outer trolley body block 6 on one side of the top of the rail 5, one end of the second stop block 3 is rotatably connected with the first stop block 1 through the axial screw 2, and the third stop block 4 is mounted on the outer trolley body block 6 on the other side of the top of the rail 5;
the four corners of the first stop block 1 are provided with through holes a, the center point of the first stop block 1 is provided with a rotating hole, and the shaft position screw 2 is rotatably connected with the rotating hole through a bearing;
wherein, four corners of the third block 4 are provided with through holes b;
the second stop block 3 is a square strip with two semicircular ends, a through hole c is formed in one end of the second stop block 3, and the shaft position screw 2 sequentially penetrates through the through hole c and the rotating hole;
the first block 1 and the third block 4 are connected with an outer vehicle body block 6 in the inspection trolley assembly through M3 screws, the second block 3 is connected with the first block 1 through a shaft position screw 2,
the second stop block 3 can swing around the axial screw 2 in a rotating mode, the distance between the first stop block 1 and the third stop block 4 is L1 and is 5cm smaller than the width of the track, meanwhile, the distance between the second stop block 3 and the third stop block 4 is L2 and is 5cm smaller than the width of the track, and when the inspection trolley is in derailment risk or wheels are derailed, the design distance is smaller than the width of the track, so that the trolley can be clamped and does not fall off after being actually derailed; the first stop block 1 and the second stop block 3 are connected through the shaft position screw 2, the second stop block 3 can rotate around the shaft position screw 2, and the second stop block 3 can rotate around the shaft position screw 2 when the trolley runs in combination with the figure 1, so that the second stop block 3 cannot be clamped with the track mounting bracket 7 when the trolley runs, the normal running of the trolley is not influenced, and meanwhile, the derailing and falling prevention protection of the inspection trolley can be realized;
to sum up, this structure takes place the derailment risk or the wheel derails when patrolling and examining the dolly, because above design distance is less than the track width like this, can block the dolly and do not take place to drop when the dolly really derails after, realize not influencing the dolly normal operating simultaneously, also can play and patrol and examine the dolly and derail the protection of preventing falling.
The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed.
