[0001] The present invention relates to the technical field of track detection, in particular to urban rail transit fault detection equipment. Background Art

[0002] In the existing equipment, when fault detection is performed on urban rails, some detection equipment is often disassembled for transportation for ease of carrying, and then assembled during operation. For example, the total station inertial navigation track geometry state measuring instrument in the prior art, as a type of rail transit fault detection equipment, requires manual labor to take the detection equipment to the inspection site during transportation. At this time, the detection equipment is in a disassembled state, and one person is required to move the crossbeam to the rail and place it on one side of the rail, and another person moves the longitudinal beam to the other end of the rail. The two people adjust the position of the crossbeam and the longitudinal beam, and then dock and install them.

[0003] In the above technical solution, since one end of the beam is in contact with the rail and the other end has no support, one person is required to support one end of the beam to keep it horizontal during installation, and another person is required to place the longitudinal beam and connect it with the beam. This process requires two people to complete the installation. When the work intensity is high and there is a shortage of manpower, the installation operation is inconvenient.

[0036] See also Figures 1 to 6 , an urban rail transit fault detection device, comprising a crossbeam 1, one end of the crossbeam 1 is detachably mounted with a longitudinal beam 2, a housing 3 is fixedly connected to the top wall of the crossbeam 1, a battery 4 is slidably mounted on the housing 3, a direction rod 5 is rotatably mounted on the top wall of the crossbeam 1, a first running wheel 6 is rotatably mounted on one end of the crossbeam 1, and a second running wheel 7 is rotatably mounted on one end of the longitudinal beam 2;

[0037] Support device: A support device for supporting the cross beam 1 is fixedly installed on one end of the cross beam 1 close to the longitudinal beam 2.

[0038] When performing track fault detection, the disassembled fault detection equipment is manually transported to the place to be inspected, and the beam 1 is manually moved to one end of the track for placement. At this time, the first running wheel 6 located at one end of the beam 1 contacts and rests on the top wall of the rail, and the first running wheel 6 is used to support one end of the beam 1. The supporting device located at the other end of the beam 1 is manually started, and the bottom of the supporting device contacts the ground between the rails to support one end of the beam 1 so that the beam 1 is parallel to the plane of the rail. After placing the beam 1, the longitudinal beam 2 is moved to the other side of the rail, and the second running wheel 7 on the longitudinal beam 2 contacts the top wall of the rail. At this time, since the supporting device supports one end of the beam 1 and is in a horizontal position, only one person can move the longitudinal beam 2 to align with the beam 1, and then the longitudinal beam 2 The interface of the longitudinal beam 2 and the crossbeam 1 is docked. When the interface of the longitudinal beam 2 and the crossbeam 1 is docked and fixed, the battery 4 is installed on the shell 3. The battery 4 is installed in the shell 3 to provide a power source for the track flatness detection equipment installed on the crossbeam 1 and the longitudinal beam 2, and the direction rod 5 is rotated and installed on the crossbeam 1. A person holds the direction rod 5 and pushes the entire detection equipment to move on the track. In the above technical solution, a supporting device is provided to support one end of the crossbeam 1 when placing the crossbeam 1 so that the crossbeam 1 is in a horizontal position, and then the longitudinal beam 2 is moved to the position corresponding to the crossbeam 1 for docking. There is no need for a person to support one end of the crossbeam 1 and wait for another person to take the longitudinal beam 2 for docking. This installation process only requires one person to complete the installation, saving manpower and improving the convenience of installation operation.

[0039] As an embodiment of the present invention, refer to Figures 1 to 6 , the supporting device comprises:

[0040] A first limiting plate 19, an end of the side wall of the cross beam 1 close to the longitudinal beam 2 is fixedly connected to the first limiting plate 19, and a first limiting groove 22 is formed on the first limiting plate 19;

[0041] A second limiting plate 21 is fixedly connected to one end of the side wall of the cross beam 1 close to the longitudinal beam 2. A second limiting groove 23 is formed on the second limiting plate 21, and the opening directions of the first limiting groove 22 and the second limiting groove 23 are perpendicular to each other;

[0042] A support rod 8 is rotatably mounted on one end of the cross beam 1 close to the longitudinal beam 2 , and a third spring 20 is elastically connected between the support rod 8 and the cross beam 1 .

[0043] When the cross beam 1 is placed, one end of the support rod 8 is embedded in the second limiting groove 23 on the second limiting plate 21, and the support rod 8 is in a horizontal position parallel to the cross beam 1. During installation, the support rod 8 is pulled open in a direction perpendicular to the side wall of the cross beam 1, and the top end of the support rod 8 leaves the second limiting groove 23 and is free from the limitation of the second limiting groove 23. Then the support rod 8 is rotated 90 degrees along the central axis of the third spring 20 to keep it vertical with the ground; after the support rod 8 is rotated, the support rod 8 is parallel to the opening direction of the first limiting groove 22, and the top of the support rod 8 is aligned with the first limiting groove 22. At this time, the support rod 8 is manually released, and the support rod 8 is subjected to the elastic pulling force of the third spring 20, abuts against the side wall of the cross beam 1, and enters the first limiting groove 22, using the first The limiting groove 22 limits the support rod 8 in the vertical direction to prevent the support rod 8 from being deflected by external force during support, thereby ensuring the stability of the support rod 8. When the measurement is completed, the support rod 8 needs to be retracted. The support rod 8 is manually pulled apart in a direction perpendicular to the side wall of the beam 1 to disengage the support rod 8 from the second limiting groove 23. The support rod 8 is rotated counterclockwise along the central axis of the third spring 20. When the top of the support rod 8 is aligned with the first limiting groove 22, the support rod 8 is released. The support rod 8 is subjected to the elastic force of the third spring 20, presses against the side wall of the beam 1, and enters the first limiting groove 22. The first limiting groove 22 is used to limit the support rod 8 in the vertical direction to prevent the support rod 8 from rotating and causing interference during transportation.

[0044] As an embodiment of the present invention, refer to Figure 6 A limit rod 26 is threadedly connected to the side wall of the support rod 8.

[0045] The support rod 8 is a telescopic rod. Since the height of each rail is inconsistent, the support rod 8 is set to be telescopic to adapt to the height of the rail. The limit rod 26 is threadedly connected to the side wall of the support rod 8. When the length of the support rod 8 needs to be adjusted, the support rod 8 is manually pulled to adjust the length. When the support rod 8 is extended to the required length, the limit rod 26 is rotated to clamp the inner rod of the support rod 8 to fix the length of the support rod 8 and improve the stability of the telescopic support rod 8.

[0046] As an embodiment of the present invention, refer to Figure 6 A clamping rod 10 is elastically connected to the side wall of the longitudinal beam 2 close to the cross beam 1 through a first spring 11, and an elastic rod 9 is rotatably installed on the top wall of the clamping rod 10. A clamping hole 25 that cooperates with the clamping rod 10 is opened on the inner wall of the cross beam 1, and the clamping rod 10 extends into the cross beam 1 through the clamping hole 25.

[0047] After the crossbeam 1 is placed, the longitudinal beam 2 is moved to the position corresponding to the crossbeam 1, the opening of the longitudinal beam 2 is aligned with the crossbeam 1, and the longitudinal beam 2 is moved in the direction of the crossbeam 1. Since the width and length of the outer wall of one end of the crossbeam 1 are smaller than the width and length of the inner wall of the longitudinal beam 2, one end of the crossbeam 1 enters the longitudinal beam 2, and the outer wall of the crossbeam 1 contacts the inner wall of the longitudinal beam 2. The crossbeam 1 continues to penetrate into the longitudinal beam 2, and the end wall of the crossbeam 1 abuts against the oblique opening of the clamping rod 10, forming an axial thrust on the clamping rod 10, and the clamping rod 10 is clamped. The rod 10 is pushed and moves toward the outer wall of the longitudinal beam 2, and will not form an obstacle to the cross beam 1. The clamping hole 25 is a through hole. When the clamping hole 25 is aligned with the position of the clamping rod 10, the first spring 11 pushes the clamping rod 10 toward the inner wall of the longitudinal beam 2, and the clamping rod 10 is embedded in the clamping hole 25, thereby forming a limited clamping for the cross beam 1. In this process, it is only necessary to manually apply a thrust to the longitudinal beam 2, and no additional tightening and fixing operation is required. The operation is convenient and simple, which improves the convenience of installation.

[0048] When the equipment needs to be disassembled, a person manually presses the end of the spring rod 9, and one end of the spring rod 9 is rotatably connected to the clamping rod 10. The spring rod 9 is a V-shaped rod, and the bottom end of the spring rod 9 is arc-shaped. The arc-shaped bottom end of the spring rod 9 rests on the outer wall of the longitudinal beam 2. When a person manually presses one end of the spring rod 9, an axial pulling force is formed on the clamping rod 10. The spring rod 9 compresses the first spring 11 to move toward the outer wall of the longitudinal beam 2, disengages from the clamping hole 25, cancels the limit on the cross beam 1, and moves the longitudinal beam 2 in the horizontal direction to complete the disassembly. By setting the above structure, fixed installation can be completed without external fastening screws.

[0049] As an embodiment of the present invention, refer to Figure 5 A slide groove is provided on the side wall of the longitudinal beam 2 facing the cross beam 1, and a buffer pad 12 is slidably installed in the slide groove.

[0050] A slide groove is opened on the side wall of the longitudinal beam 2 facing the cross beam 1, and a buffer pad 12 is fixedly installed in the slide groove. During installation, the end wall of the cross beam 1 facing the longitudinal beam 2 first contacts the buffer pad 12. The buffer pad 12 buffers the cross beam 1 in the horizontal direction to prevent excessive manual force from being used during the installation process, causing a strong collision between the cross beam 1 and the longitudinal beam 2, thereby causing greater wear on the cross beam 1 and the longitudinal beam 2, thereby improving the safety of the installation operation.

[0051] As an embodiment of the present invention, refer to Figure 3 A handle 14 is fixedly connected to the top wall of the battery 4, a push rod 28 is rotatably installed on the battery 4, and the push rod 28 passes through the battery 4 and extends into the shell 3, a rotating block 16 is rotatably installed on the inner wall of the shell 3, a second spring 17 is elastically connected between the rotating block 16 and the inner wall surface of the shell 3, and a limit block 18 is fixedly connected to the inner wall of the shell 3, and the limit block 18 is located obliquely above the rotating block 16.

[0052] After the cross beam 1 and the longitudinal beam 2 are fixedly installed, the battery 4 needs to be installed and fixed. When installing the battery 4, the battery 4 to be installed is manually placed in the shell 3, and a rotating block 16 is rotatably installed on the inner wall of the shell 3. One end of the rotating block 16 is arc-shaped, and a second spring 17 is elastically connected between the rotating block 16 and the inner wall of the shell 3. When the battery 4 enters the shell 3, the bottom wall of the battery 4 first contacts the side wall of the rotating block 16, applying a downward thrust to the rotating block 16. The downward thrust forms a horizontal component force on the rotating block 16, and the rotating block 16 compresses the second spring 17 and rotates clockwise until the arc-shaped side wall of the rotating block 16 is in contact with the inner wall of the shell 3. The battery 4 continues to move downward, and when the bayonet 27 on the battery 4 is aligned with the rotating block 16, the second spring 17 suddenly reduces the pressure due to which it pushes the rotating block 16 inward in the direction of the bayonet 27, and the arc-shaped bottom wall of the rotating block 16 abuts against the edge of the bayonet 27, and the bayonet 27 is locked and locked, thereby locking the battery 4, and a limiting block 18 is fixedly connected to the upper side of the rotating block 16, and the limiting block 18 is used to limit the rotating block 16 in the vertical direction to prevent the rotating block 16 from rotating too much. When the arc-shaped bottom wall of the rotating block 16 contacts the edge of the bayonet 27, the top wall of the rotating block 16 just contacts the limiting block 18, thereby more stably fixing the battery 4.

[0053] When it is necessary to remove the battery 4, the push rod 28 is manually pressed downward, and the push rod 28 moves downward. The arc-shaped bottom wall at the bottom of the push rod 28 contacts the side wall of the rotating block 16, exerting a downward thrust on the rotating block 16. The second spring 17 contracts under the pressure, and the rotating block 16 rotates clockwise, canceling the locking effect on the bayonet 27. The battery 4 can be pulled out of the housing 3 by grasping the handle 14 and lifting it upward, thereby achieving the goal of lifting the battery 4 while releasing the limit, thereby improving the convenience of removing the battery 4.

[0054] As an embodiment of the present invention, refer to Figure 3 One end of the push rod 28 away from the housing 3 is fixedly connected to the rotating handle 15 .

[0055] A rotating handle 15 is fixedly connected to the top of the push rod 28, and the rotating handle 15 is arc-shaped. When removing the battery 4, a person holds the rotating handle 15 and pushes the rotating handle 15 downward. The rotating handle 15 pushes the push rod 28 to move downward. When the top wall of the rotating handle 15 moves to a position flush with the handle 14, the person holds the handle 14 and lifts it upward, thereby lifting the battery 4 upward to complete the removal of the battery 4. Through the above mechanism and process, the convenience of removing the battery 4 is improved.

[0056] As an embodiment of the present invention, refer to Figure 2One end of the clamping rod 10 away from the first spring 11 is an inclined opening, and a roller is rotatably mounted on the inclined opening.

[0057] When the crossbeam 1 and the longitudinal beam 2 are docked and installed, one end of the crossbeam 1 enters into the longitudinal beam 2, and the end face of the crossbeam 1 contacts the roller on the inclined opening. Since one end of the clamping rod 10 is arranged to be inclined, when the end face of the crossbeam 1 contacts the roller and applies pressure to the roller, the clamping rod 10 will compress the first spring 11 and move toward the outer wall of the longitudinal beam 2, thereby not blocking one end of the crossbeam 1 from entering the interior of the longitudinal beam 2, thereby reducing the wear on the end of the crossbeam 1 and the inclined opening of the clamping rod 10 during the docking process of the crossbeam 1 and the longitudinal beam 2.

[0058] As an embodiment of the present invention, refer to Figure 6 A supporting base plate 24 is fixedly mounted on one end of the supporting rod 8 away from the cross beam 1 .

[0059] A support base plate 24 is fixedly installed at one end of the support rod 8 away from the beam 1. When the support rod 8 rotates to a position at an angle with the beam 1, the support base plate 24 contacts the ground. The support base plate 24 is fixedly installed at the bottom of the support rod 8, which increases the contact area between the support rod 8 and the ground, thereby improving the stability of the support rod 8 in supporting the beam 1.

[0060] As an embodiment of the present invention, refer to Figure 6 A vacuum suction cup 13 is fixedly mounted on the bottom wall of the supporting base plate 24 .

[0061] During the installation process, when the support rod 8 is rotated to an angle of degrees, the vacuum suction cup 13 on the lower wall of the support base plate 24 contacts the ground, and the rocker of the vacuum suction cup 13 is manually pressed. The structure of the vacuum suction cup 13 is the existing technology, and the vacuum suction cup 13 is adsorbed on the ground, thereby enhancing the adsorption force between the support base plate 24 and the ground, ensuring the stability of the contact between the support base plate 24 and the ground. When the cross beam 1 and the longitudinal beam 2 are docked, the longitudinal beam 2 is manually pushed to move in the direction of the cross beam 1, which will generate a thrust on the cross beam 1. At this time, since the vacuum suction cup 13 on the support base plate 24 is adsorbed on the ground, and the equipment of the present application is located in the rail part of the station, at the starting position, a smooth stone slab is provided to cooperate with the vacuum suction cup 13. To achieve the limiting effect; the vacuum suction cup 13 is used to limit the crossbeam 1 during the installation of the detection equipment, so as to avoid the movement of the main structure such as the crossbeam 1 and the longitudinal beam 2 due to the pulling force during the installation, which will hinder the installation; in this way, during the installation process, when the longitudinal beam 2 is manually pushed, the crossbeam 1 will not tip over or retreat, thereby improving the safety of the docking operation between the crossbeam 1 and the longitudinal beam 2. When the overall installation is completed, the second walking wheel 7 and the first walking wheel 6 are respectively located on both sides of the rail to support the whole. At this time, the vacuum suction cup 13 is released to release the limiting effect, and the support rod 8 is manually rotated to a horizontal position parallel to the crossbeam, and then the direction rod 5 is pushed to push the overall equipment to run on the track.

[0062] Working principle: When performing track fault detection operation, the crossbeam 1 is manually moved to the rail and placed on one side of the rail. The first running wheel 6 on the crossbeam 1 contacts the upper surface of the rail to support one end of the crossbeam 1. The support rod 8 is manually pulled in the direction perpendicular to the side wall of the crossbeam 1, and the support rod 8 is disengaged from the first limiting groove 22. The support rod 8 is rotated counterclockwise by 8 degrees so that the support bottom plate 24 at the bottom of the support rod 8 contacts the ground, thereby supporting one end of the crossbeam 1 so that the crossbeam 1 is in a horizontal position parallel to the plane of the rail. Then the longitudinal beam 2 is moved to a position symmetrical to the crossbeam 1, and the position of the longitudinal beam 2 is manually moved so that the longitudinal beam 2 is aligned with the crossbeam 1. The longitudinal beam 2 is pushed in the direction of the crossbeam 1 so that one end of the crossbeam 1 enters the interior of the longitudinal beam 2. After one end of 1 enters the interior of the longitudinal beam 2, the end wall of the cross beam 1 contacts the roller on the clamping lever, exerting pressure on the roller, and the clamping lever 10 is subjected to the thrust to compress the first spring 11 and move toward the outer wall of the longitudinal beam 2, thereby not forming an obstacle to the cross beam 1, and the cross beam 1 continues to enter the interior of the longitudinal beam 2. When the clamping hole 25 on the cross beam 1 is aligned with the position of the clamping lever 10, the clamping lever 10 is subjected to the thrust of the first spring 11 and is embedded in the clamping hole 25, thereby forming a limiting effect on the clamping hole 25, thereby locking the cross beam 1. In this process, only a person needs to push the longitudinal beam 2 to complete the locking operation. When disassembling, a person manually presses the spring rod 9 located on the side wall of the longitudinal beam 2, and the spring rod 9 drives the clamping lever to compress the first spring 11, cancels the limit on the clamping hole 25, and then pulls the longitudinal beam 2, thereby completing the disassembly process.

[0063] After the installation and fixation of the crossbeam 1 and the longitudinal beam 2 are completed, the battery 4 is installed and manually placed on the shell 3. The battery 4 enters the shell 3, and the bottom wall of the battery 4 contacts the side wall of the rotating block 16. Pressure is applied to the rotating block 16, and the rotating block 16 rotates clockwise until it is flush with the inner wall of the shell 3, so that the battery 4 is conveniently inserted into the shell 3. When the bayonet 27 on the battery 4 is aligned with the position of the rotating block 16, the second spring 17 pushes the rotating block 16 to rotate into the bayonet 27. When the side wall of the rotating block 16 contacts the limit block 18, the rotating block 16 is rotated. The arc-shaped bottom wall of the movable block 16 just contacts the edge of the bayonet 27, thereby clamping and limiting the bayonet 27. When the battery 4 needs to be removed, the person holds the rotating handle 15 and pushes the push rod 28 downward. The bottom of the push rod 28 contacts the side wall of the rotating block 16, exerting a downward thrust on the rotating block 16. The rotating block 16 rotates counterclockwise until it is flush with the inner wall of the shell 3. The rotating block 16 cancels the limit on the bayonet 27. At this time, the rotating handle 15 is flush with the handle 14. The person holds the handle 14 and lifts it upward to complete the removal of the battery 4.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
