Description

Technical Field

[0001] The invention relates to the technical field of derailment and falling prevention of a traction trolley, in particular to a derailment and falling prevention device for a patrol trolley. Background Art

[0002] At present, the track of the underground inspection trolley is basically hoisted through the underground top plate rivet rod, and the rivet cable hangs the robot track, so that the inspection trolley can walk well on the track, and at the same time, the function of the inspection robot is used to monitor the underground conditions. In this way, when the robot is running on the track, it may derail and fall, which is very easy to cause danger. In view of such defects, it is necessary for us to design a derailment and falling prevention device for the inspection trolley. Summary of the invention

[0003] The object of the present invention is to provide a kind of inspection trolley anti-derail falling device, when the inspection trolley derails risk or wheel derailment occurs, like this because the above design distance is less than the track width, when the trolley is really derailed, the trolley can be stuck and not fall, and simultaneously when the normal operation of the trolley is not affected, the derailment anti-falling protection of the inspection trolley can also be played.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] The inspection trolley anti-derailment and falling device comprises a first stopper, an axial screw, a second stopper, a third stopper, a track, an outer car body block and a mounting bracket, wherein the track is fixedly mounted by the mounting bracket, a plurality of outer car body blocks are symmetrically and equidistantly arranged on both sides of the top of the track, a first stopper is mounted on the outer car body block on one side of the top of the track, and one end of the second stopper is rotatably connected to the first stopper by the axial screw, and a third stopper is mounted on the outer car body block on the other side of the top of the track.

[0006] As a further solution of the present invention: through holes a are provided at four corners of the first stopper, and a rotating hole is provided at the center point of the first stopper, and the axial screw is rotatably connected to the rotating hole via a bearing.

[0007] As a further solution of the present invention: through holes b are provided at four corners of the third stopper.

[0008] As a further solution of the present invention: the second stopper is a square bar-shaped body with semicircular ends, and a through hole c is opened at one end of the second stopper, and the axial screw passes through the through hole c and the rotation hole in sequence.

[0009] The beneficial effects of the present invention are as follows: when the trolley is running, the second stop block can rotate around the axial screw, so that when the trolley is running, the second stop block will not be stuck with the track mounting bracket, and will not affect the normal operation of the trolley, but at the same time can play a role in preventing the inspection trolley from derailing and falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the accompanying drawings.

[0014] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] like Figure 1-2 As shown, the inspection trolley anti-derailment and falling device comprises a first stopper 1, an axial screw 2, a second stopper 3, a third stopper 4, a track 5, an outer car body block 6 and a mounting bracket 7, the track 5 is fixedly installed by the mounting bracket 7, a plurality of outer car body blocks 6 are symmetrically and equidistantly arranged on both sides of the top of the track 5, and the first stopper 1 is installed on one side of the top of the track 5 on the outer car body block 6, and one end of the second stopper 3 is rotatably connected to the first stopper 1 by the axial screw 2, and the third stopper 4 is installed on the other side of the top of the track 5 on the outer car body block 6;

[0016] Among them, through holes a are opened at the four corners of the first stopper 1, and a rotating hole is opened at the center point of the first stopper 1, and the axial screw 2 is rotatably connected with the rotating hole through a bearing;

[0017] Among them, the third stopper 4 has through holes b at four corners;

[0018] The second stopper 3 is a square bar with semicircular ends, and a through hole c is formed at one end of the second stopper 3, and the axial screw 2 passes through the through hole c and the rotation hole in sequence;

[0019] The first stopper 1 and the third stopper 4 are connected to the outer car body block 6 in the inspection car assembly through M3 screws, and the second stopper 3 is connected to the first stopper 1 through the axial screw 2.

[0020] The second stopper 3 can rotate and swing around the axial screw 2. The distance L1 between the first stopper 1 and the third stopper 4 is 5 cm smaller than the track width. At the same time, the distance L2 between the second stopper 3 and the third stopper 4 is 5 cm smaller than the track width. When the inspection trolley is at risk of derailment or the wheels derail, the trolley can be stuck and will not fall after it is actually derailed because the above designed distance is smaller than the track width. The first stopper 1 and the second stopper 3 are connected by the axial screw 2, and the second stopper 3 can rotate around the axial screw 2. Figure 1 When the trolley is running, the second stopper 3 can rotate around the axial screw 2, so that when the trolley is running, the second stopper 3 will not be stuck with the track mounting bracket 7, and will not affect the normal operation of the trolley, but at the same time it can protect the inspection trolley from derailment and falling;

[0021] To sum up, with this structure, when the inspection trolley is at risk of derailment or the wheels are derailed, since the above designed distance is less than the track width, the trolley can be stuck and prevented from falling after it actually derails. At the same time, it can also protect the inspection trolley from derailment and falling without affecting the normal operation of the trolley.

[0022] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. The present invention is limited only by the claims and their full scope and equivalents.
