Description

Technical Field

[0001] The invention belongs to the technical field of measurement and testing, specifically to a linear dimension measuring device, and more particularly to a track wear automatic detection marking vehicle and a use method thereof. Background Art

[0002] In the suspended conveying system, the channel steel track is the basis for ensuring the stability of the equipment and running according to the predetermined trajectory. At the same time, it also bears the weight of the conveying vehicle and the conveying load. It is one of the most important components of the suspended conveying system. The running trajectory of the conveying vehicle depends entirely on the track. The accuracy of the track spacing determines the accuracy of the running trajectory of the conveying vehicle. The shape of the track channel affects the stability of the conveying vehicle during operation. Therefore, it is necessary to regularly inspect the track spacing and the shape of the track channel to ensure the reliable operation of the conveying system.

[0003] The unfolded length of the suspended conveying system is more than 100 meters and the height is about 4 meters. The existing technology mostly adopts the method of checking and processing during shutdown and maintenance. This method is inefficient and the workload cannot be determined in advance.

[0004] Chinese invention patent CN 105783836 B proposes an automatic track wear detection vehicle that can complete fully automatic track gap inspections, has high detection accuracy, can determine the workload in advance, and reduces the labor intensity of workers. However, it also has the following obvious defects: large investment in supporting facilities, the data output by the detection vehicle needs to be converted twice to correspond to the on-site location, and the automatic detection vehicle needs to be driven by batteries during operation, resulting in high operating costs.

[0005] In summary, the existing technology has problems such as large investment in supporting facilities, high operating costs, and the inability to carry out detection and marking at the same time, which need to be improved. Summary of the invention

[0006] In view of this, an embodiment of the present invention provides a track wear automatic detection and marking vehicle and a method of using the same to solve the technical problems in the prior art of large investment in supporting facilities, high operating costs, and the inability to perform detection and marking simultaneously.

[0007] The technical solution proposed by the present invention is as follows:

[0008] A track wear automatic detection and marking vehicle comprises a front trolley, a rear trolley, two middle trolleys arranged front and rear between the front trolley and the rear trolley, a first pin shaft, a second pin shaft, a first load beam, and a second load beam. There are two first load beams, one of which is connected to the front trolley and the middle trolley at the front through a first pin shaft, and the other first load beam is connected to the middle trolley at the rear and the rear trolley through a first pin shaft. The second load beam is connected to the two first load beams through second pin shafts at both ends.

[0009] It also includes a spacing detection device and an on-site identification device. The spacing detection device is arranged on the small and medium-sized car close to the rear car, and the spacing measurement device is detachably installed on the guide wheel of the small and medium-sized car away from the traveling direction, so as to facilitate the replacement of the original guide wheel; the on-site identification device is fixedly installed on the first load beam connected to the small and medium-sized car where the spacing measurement device is located.

[0010] Specifically, the spacing detection device includes a base, a movable detection claw, a rotating shaft, a tensioning spring and a proximity switch. The base is detachably mounted on the guide wheel of the trolley away from the direction of travel. Fixed detection claws are upwardly arranged at both ends of one side of the base (the top here), and a movable detection claw is connected to the other side (the bottom here) through a rotating shaft. The fixed detection claw is close to the track to be measured; one end of the movable detection claw close to the direction of travel is close to the track to be measured, and the other end is connected to the base through a tensioning spring. When the tensioning spring contracts, the end of the movable detection claw close to the direction of travel is attached to the track to be measured. A proximity switch is arranged below the end of the movable detection claw away from the direction of travel, and the proximity switch is connected to the on-site identification device through a wire.

[0011] Specifically, the on-site identification device includes a base, a first power supply, a second power supply, a relay, a contactor and an electric paint spraying device. The base is arranged on a first load beam, and the first power supply, the second power supply, the relay, the contactor and the electric paint spraying device are all fixed on the base. The first power supply, the proximity switch and the relay are connected in sequence to form a control circuit, and the second power supply, the contactor, the normally open contact of the relay and the electric paint spraying device form a main circuit. The relay is connected to the proximity switch through a wire; the nozzle of the electric paint spraying device is arranged on the outside of the track to be tested, facing the outer surface of the track to be tested.

[0012] Specifically, a wear-resistant block is provided at the end of the movable detection claw facing the track to be detected.

[0013] Specifically, the wear-resistant block is spherical.

[0014] Specifically, the fixed detection claw is in the shape of a horn.

[0015] The present invention also includes a method for using a track wear automatic detection and marking vehicle, which adopts the technical solution of the track wear automatic detection and marking vehicle and is performed according to the following steps:

[0016] A. Assemble a track wear automatic detection and marking vehicle in the maintenance area, confirm that the fixed detection claw is in close contact with the track to be tested, confirm that the end of the movable detection claw close to the travel direction is in close contact with the track to be tested and the end away from the travel direction is located in the detection area above the proximity switch, confirm that the proximity switch signal is normal, and confirm that the nozzle of the electric spray paint device is set outside the track to be tested and facing the outer surface of the track to be tested;

[0017] B. Push the track wear automatic detection marking vehicle into the operation area;

[0018] C. When the track wear automatic detection marking vehicle runs to the position where the track to be tested is severely worn, the movable detection claw rotates clockwise around the axis, and the end away from the direction of travel deviates from the detection area above the proximity switch, and the proximity switch loses the signal;

[0019] D. The relay in the control circuit is energized, the contactor contacts are closed, the electric spray paint device is started, and the nozzle sprays marks on the outer surface of the track to be tested;

[0020] E. The track wear automatic detection marking vehicle continues to run and drives out of the position where the track to be tested is severely worn. The movable detection claw rotates counterclockwise around the rotating shaft, and the end away from the travel direction returns to the detection area above the proximity switch, and the proximity switch gets the signal again;

[0021] F. The relay in the control circuit loses power, the normally open contact of the contactor opens, and the electric spray paint device stops;

[0022] G. Repeat steps C to F until all the areas to be tested are marked;

[0023] H. Push the automatic track wear detection and marking vehicle into the maintenance area and cut off the power for standby use.

[0024] The beneficial effects achieved by the present invention are: by adopting the above-mentioned technical scheme, it is only necessary to utilize the existing carrier for modification, and the investment cost is low. The drive of the automatic track wear detection and marking vehicle adopts the original drive of the suspended conveying system, and no additional investment is required. The operating cost is also low. During the detection, markings are made on site, which is clear to the maintenance personnel, making it easy to determine the workload, material consumption, etc. in advance.

[0025] The invention has low investment cost and low operation cost. The invention can make marks on site during detection, thus solving the technical problem of being unable to mark in the prior art and having extremely high promotion and application value. BRIEF DESCRIPTION OF THE DRAWINGS
