Description

Technical field:

[0001] The present invention relates to the technical field of track detection, and in particular to an intelligent detection system for high-altitude tracks. Background technology:

[0002] At present, the detection of various parameters of domestic crane aerial tracks mainly adopts manual measurement methods, which are not only low in accuracy, time-consuming, inefficient, and difficult to implement, but also have major safety hazards in aerial operations.

[0003] As for the intelligent trolley detection system, most of the research results in China are from scholars in universities. Most of them remain in the research and experimental stage and have not been truly transformed into products. In addition, there are many defects in the design of the trolley. There are similar products abroad, but the degree of automation is not high. A single trolley can only measure guide rails of fixed sizes, and cannot measure guide rails with a large size span or some special guide rails. Moreover, due to the influence of the environment in which the track is located, this type of trolley is prone to shaking, which not only affects the measurement accuracy but also makes it easy to cause danger.

[0004] Although the applicant's prior application No. 201820458828.5 intelligent detection trolley for high-altitude rails of lifting machinery has solved the above-mentioned problems, its structure is relatively complex and its assembly is very inconvenient. After the trolley deviates to the left or right, it cannot be corrected, thus affecting the measurement accuracy. Summary of the invention:

[0005] The purpose of the present invention is to provide a high-altitude track intelligent detection system with simple structure, convenient assembly, high safety and guaranteed detection accuracy in view of the defects of the prior art.

[0006] The present invention is realized by the following technical scheme: an intelligent detection system for high-altitude rails, comprising a frame and a detection mechanism, a moving mechanism, a guide clamping mechanism, and an automatic deviation correction mechanism arranged on the frame.

[0007] The moving mechanism includes a driver and a roller, the driver is connected to the roller, the roller is arranged at the top of the guide rail to be measured, and the driver can drive the roller to roll along the guide rail to be measured;

[0008] The guide clamping mechanism is divided into two groups, each group of the guide clamping mechanism includes a first reduction motor, a screw rod, two clamping blocks and two elastic guide wheel assemblies, the two clamping blocks are arranged on the screw rod, the two elastic guide wheel assemblies are respectively arranged in the two clamping blocks, the two elastic guide wheel assemblies are against the two side surfaces of the guide rail to be measured, the first reduction motor is connected to the screw rod, and the first reduction motor can drive the two clamping blocks to move inward or outward at the same time through the screw rod to clamp or release the guide rail to be measured;

[0009] The automatic deviation correction mechanism includes two second reduction motors, two worm gears, two turbine assemblies, two lifting rods and a positioning seat. The two lifting rods are respectively arranged at the bottom ends of the two turbine assemblies and correspondingly arranged above the guide rail to be measured. The positioning seat sleeve is arranged outside the two lifting rods. The two second reduction motors are respectively connected to the two turbine assemblies through two worm gears. The second reduction motors can drive the lifting rods to rise and fall through the worm gear and the turbine assembly.

[0010] In order to ensure the clamping effect and avoid slipping, the two clamping blocks have anti-slip teeth on the two surfaces opposite to the guide rail to be measured, and the clamping blocks have through grooves.

[0011] In order to avoid squeezing the guide wheel during the clamping process, the elastic guide wheel assembly includes a spring sleeve and a guide wheel, the spring sleeve is fixed to the clamping block, and the guide wheel is elastically connected to the spring sleeve.

[0012] In order to guide the lifting and lowering of the lifting rod, the lifting rod is threadedly connected with the turbine assembly, a tooth groove is provided in the positioning seat, and a rack is provided on the lifting rod, and the rack slides up and down along the tooth groove.

[0013] The beneficial effect of the present invention is that the high-altitude track intelligent detection system cooperates with a specially designed guide clamping mechanism and an automatic deviation correction mechanism. If the trolley deviates during operation, it can be automatically clamped and automatically corrected, thereby avoiding the trolley from tipping over and ensuring the detection accuracy.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] like Figure 1The high-altitude track intelligent detection system shown includes a frame 1 and a detection mechanism, a moving mechanism 2, a guide clamping mechanism 3, and an automatic correction mechanism 4 arranged on the frame 1. The detection mechanism includes an intelligent imaging system 6, a rangefinder 7, a tilt switch 8, a network camera 9, etc. In addition, a battery 5 is also provided.

[0021] like Figure 2 The moving mechanism shown includes a driver and rollers 25. The driver includes a motor 21, a reducer 22, a pulley set 23 and a rotating shaft 24. Two rollers 25 are arranged on the rotating shaft 24. The two rollers 25 are arranged at the top of the guide rail to be tested. The driver serves as the power of the entire trolley and can drive the rollers 25 to roll along the guide rail to be tested.

[0022] like Figure 3 The guide clamping mechanism shown in the figure is composed of two groups of guide clamping mechanisms, each group of guide clamping mechanisms includes a first reduction motor 31, a screw rod 32, two clamping blocks 33, two guide wheels 35 and two spring sleeves 36. The two clamping blocks 33 are arranged on the screw rod 32 and guided by the guide rod 34. The two spring sleeves 36 are fixed to the bottom ends of the two clamping blocks 33 through mounting seats. The two guide wheels 35 are elastically connected to the two spring sleeves 36 respectively, and the two guide wheels 35 abut against the two side surfaces of the guide rail to be measured. The two clamping blocks 33 have anti-slip teeth 331 on the two surfaces opposite to the guide rail to be measured, and the clamping blocks have through grooves, in which the guide wheels 35 are arranged. The first reduction motor 31 is connected to the screw rod 32. The first reduction motor 31 can drive the two clamping blocks 33 to move inward or outward at the same time through the screw rod 32 to clamp or release the guide rail to be measured.

[0023] like Figure 4 The automatic deviation correction mechanism shown includes two second reduction motors 41, two worm gears 43, two turbine assemblies 44, two lifting rods 45 and a positioning seat 46. The two lifting rods 45 are respectively arranged at the bottom ends of the two turbine assemblies 44 and are correspondingly arranged above the guide rail to be measured. The positioning seat 46 is sleeved outside the two lifting rods 45. The two second reduction motors 41 are respectively connected to the two worm gears 43 through two couplings 42, and the two worm gears 43 are respectively connected to the two turbine assemblies 44.

[0024] like Figure 5 The lifting rod 45 and the positioning seat 46 are shown, the lifting rod 45 is threadedly connected to the turbine assembly, the positioning seat 46 is provided with two tooth grooves 461, the lifting rod 45 is provided with a rack 451, and the rack 451 is embedded in the tooth groove 461 to achieve lifting and guiding.

[0025] Reference Figure 1-5As shown, when in use, the driver drives the roller 25 to roll, thereby driving the entire trolley to move along the guide rail to be measured, and the four guide wheels 35 guide. When the inclination switch 8 senses that the trolley is tilted, the first reduction motor 31 operates to drive the screw 32 to rotate, and the screw 32 drives the two clamping blocks 33 to move inward at the same time, and the two clamping blocks 33 can clamp the guide rail to be measured, and each guide wheel 35 shrinks; at this time, the automatic deviation correction mechanism operates, and one of the second reduction motors 41 drives the turbine assembly 44 to rotate through the worm 43, and the turbine assembly 44 drives the lifting rod 45 to descend. After the lifting rod 45 hits the guide rail to be measured, it continues to descend, and the entire side of the trolley can be gradually lifted up until the inclination switch 8 senses that the trolley is completely horizontal, and automatic deviation correction is achieved. For example, when the trolley tilts to the lower left, the second reduction motor 41 on the left side drives the lifting rod 45 on the left side to descend through the worm 43 and the turbine assembly 44, and the lifting rod 45 on the left side can push the left side of the trolley upward to a horizontal position.
