Description

Technical Field

[0001] This utility model relates to the technical field of equipment for inspecting weld seams of conveyor trusses, and more specifically, to a crawler for inspecting weld seams of conveyor trusses. Background Technology

[0002] Conveyor trusses are the core support structure of material conveying systems in industrial production, widely used in mining, ports, metallurgy, chemical, and power industries. They are typically welded from large steel structures and withstand heavy loads, vibrations, corrosion, and other complex conditions over long periods. The quality of the welds directly affects the structural safety and service life of the truss. Traditional manual inspection methods are inefficient and pose safety hazards; therefore, the development of automated weld inspection equipment has become an urgent need in the industry.

[0003] Currently, the inspection of welds on conveyor trusses is mainly carried out manually in conjunction with tools such as ultrasonic flaw detectors (UT), magnetic particle flaw detectors (MT), or penetrant detectors (PT). However, for conveyor trusses erected at high altitudes, this inspection method requires frequent manual climbing, which not only poses safety hazards but also leads to low inspection efficiency.

[0004] Therefore, in view of this, the existing structure is studied and improved to provide a crawler for inspecting weld seams of conveyor trusses, in order to achieve a more practical purpose. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a conveyor truss weld inspection crawler that can perform ultrasonic flaw detection on conveyor trusses at high locations or those that are difficult to directly access, avoiding the problem of frequent manual climbing, improving the safety of conveyor truss weld inspection, and increasing the efficiency of inspection.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A crawler for inspecting weld seams of a conveyor truss includes a main frame, an ultrasonic flaw detector fixedly installed in the middle of the main frame, a battery fixedly installed on the ultrasonic flaw detector, a front electromagnet installed at the front end of the main frame, a rear electromagnet installed at the rear end of the main frame, and a driven wheel set and a rear drive wheel set installed on the side of the main frame, with the driven wheel set close to the front electromagnet and the rear drive wheel set close to the rear electromagnet.

[0010] The structure of the driven wheel assembly is the same as that of the rear drive wheel assembly. The driven wheel assembly includes two L-shaped brackets, and each L-shaped bracket is fixedly mounted with a horizontal caster and a vertical caster.

[0011] A motor is fixed on an L-shaped bracket located on the rear drive wheel assembly. The output shaft of the motor is connected to a connecting shaft via a coupling. The other end of the connecting shaft is fixed to the center shaft of the corresponding transverse caster.

[0012] Furthermore, the main frame is a hollow structure, and a conduit connects the main frame to the battery.

[0013] Furthermore, the ultrasonic flaw detector, the front electromagnet, the rear electromagnet, and the two motors are connected in parallel in the same circuit, and each circuit has an independently installed signal control switch.

[0014] Furthermore, both the branch containing the front electromagnet and the branch containing the rear electromagnet are connected to digital potentiometers.

[0015] Furthermore, the front electromagnet and the rear electromagnet are arranged symmetrically along an axis, and the distances between the front electromagnet and the rear electromagnet and the main frame are equal.

[0016] Furthermore, the horizontal casters and the vertical casters are arranged perpendicularly to each other and are located on the two inner sides of the L-shaped bracket, respectively.

[0017] Furthermore, the main frame is a hollow structure made of plastic, and a signal transceiver is installed on the main frame.

[0018] 3. Beneficial effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] This solution utilizes a crawler equipped with an ultrasonic flaw detector.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Example:

[0035] Please see Figure 1 - Figure 4 A conveyor truss weld seam inspection crawler includes a main frame 1, an ultrasonic flaw detector 2 fixedly installed in the middle of the main frame 1, a battery 3 fixedly installed on the ultrasonic flaw detector 2, a front electromagnet 4 installed at the front end of the main frame 1, a rear electromagnet 5 installed at the rear end of the main frame 1, a driven wheel set 6 and a rear drive wheel set 7 installed on the side of the main frame 1, the driven wheel set 6 being close to the front electromagnet 4, and the rear drive wheel set 7 being close to the rear electromagnet 5.

[0036] The structure of the driven wheel assembly 6 is the same as that of the rear drive wheel assembly 7. The driven wheel assembly 6 includes two L-shaped brackets 601, and each L-shaped bracket 601 is fixedly mounted with a transverse caster 602 and a longitudinal caster 603.

[0037] A motor 701 is fixed on an L-shaped bracket 601 located on the rear drive wheel assembly 7. The output shaft of the motor 701 is connected to a connecting shaft 702 via a coupling. The other end of the connecting shaft 702 is fixed to the central shaft of the corresponding transverse caster 602.

[0038] See Figure 1 , Figure 2 Specifically, the main frame 1 is a hollow structure, and a conduit 101 connects the main frame 1 and the battery 3.

[0039] Power is supplied through conduit 101, which allows the battery 3 to supply power to the front electromagnet 4, the rear electromagnet 5, and the two motors 701.

[0040] See Figure 4 Specifically, the ultrasonic flaw detector 2, the front electromagnet 4, the rear electromagnet 5, and the two motors 701 are connected in parallel in the same circuit, and each circuit has an independent signal control switch installed.

[0041] This allows for independent control of the ultrasonic flaw detector 2, the front electromagnet 4, the rear electromagnet 5, and the two motors 701.

[0042] Specifically, digital potentiometers 401 are connected to both the branch containing the front electromagnet 4 and the branch containing the rear electromagnet 5.

[0043] The digital potentiometer 401 can be remotely controlled to control the resistance of the branch where the front electromagnet 4 is located and the branch where the rear electromagnet 5 is located. Then, the magnetic force generated by the corresponding front electromagnet 4 and rear electromagnet 5 can be controlled, which makes it convenient to adjust the magnetic force according to the situation of the crawler. When crawling vertically upward, it prevents the crawler from falling and ensures that the crawler can crawl stably upward.

[0044] See Figure 1 , Figure 2 , Figure 3 Specifically, the front electromagnet 4 and the rear electromagnet 5 are arranged symmetrically on an axis, and the distances between the front electromagnet 4 and the rear electromagnet 5 and the main frame 1 are equal.

[0045] By adjusting the distance between the front electromagnet 4 and the rear electromagnet 5, and controlling the electromagnetic forces of the front electromagnet 4 and the rear electromagnet 5 to be equal, the crawler can be guaranteed to move stably. By controlling the difference in magnetic force between the front electromagnet 4 and the rear electromagnet 5, the crawler can be controlled to tilt forward or backward, so that the ultrasonic flaw detector 2 has a higher flaw detection angle.

[0046] Specifically, the horizontal caster 602 and the vertical caster 603 are arranged perpendicularly to each other and are located on the two inner sides of the L-shaped bracket 601, respectively.

[0047] The longitudinal casters 603 can assist in contacting the sides of the truss, increasing crawling stability when the crawler is crawling.

[0048] See Figure 1 , Figure 2 Specifically, the main frame 1 is a hollow structure made of plastic, and a signal transceiver 102 is installed on the main frame 1.

[0049] The hollow structure made of plastic can reduce the weight of the entire crawler and reduce the wear and tear caused by the weight when the crawler is crawling. The use of a CC1101 signal transceiver 102 makes it easy to remotely control the crawler to move forward or backward.

[0050] Working principle:

[0051] When in use, the crawler is placed on the truss of the conveyor. The battery 3 supplies power to the front electromagnet 4, the rear electromagnet 5, and the two motors 701. At this time, the digital potentiometer 401 controls the current of the front electromagnet 4 and the rear electromagnet 5 respectively, thereby controlling the magnetic force. The magnetic force is adjusted according to the situation of the crawler to prevent the crawler from falling when crawling vertically upward, and to ensure that the crawler can climb upward stably.

[0052] During the crawling process, the motor 701, in conjunction with the connecting shaft 702, controls the rotation of the transverse caster 602 in the rear drive wheel set 7, while the longitudinal caster 603 assists in contacting the side of the truss. At the same time, the transverse caster 602 and the longitudinal caster 603 in the driven wheel set 6 rotate under thrust, completing the stable crawling of the crawler. During the crawling process, the ultrasonic flaw detector 2 performs flaw detection.

[0053] In this way, the entire device can be used.

[0054] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
