Description

Technical Field

[0001] The present invention relates to the technical field of thickness detection devices for carbon steel protective covers, and specifically provides a thickness detection device for carbon steel protective covers. Background Art

[0002] In today's industrial field, as an important component, the carbon steel protective cover has been widely used in many industrial equipment and mechanical components due to its low cost, high strength, wear resistance and many other advantages. From the protective structures of various large-scale mechanical equipment to the key components in complex automated production lines, the carbon steel protective cover can be found everywhere. It plays a crucial role in ensuring the normal operation, performance and service life of the equipment.

[0003] The thickness of the carbon steel protective cover is largely related to its overall performance and quality. An appropriate thickness can ensure that the protective cover has sufficient structural strength to withstand various external loads and impacts, maintaining the stable operation of the equipment; a moderate thickness can also take into account the lightweight requirements, reducing the overall energy consumption and operating costs of the equipment.

[0004] However, at present, the measurement of the thickness of carbon steel protective covers in the industry mainly relies on traditional manual measurement methods. There are many drawbacks in the actual application of traditional manual measurement means. On the one hand, its measurement efficiency is extremely low. The measurement personnel need to operate on each carbon steel protective cover one by one, and each measurement takes a long time. Especially in large-scale production scenarios, this low-efficiency measurement method seriously restricts the progress of the production process and cannot keep up with the fast pace requirements of modern industrial production. On the other hand, the accuracy of manual measurement is quite limited. Due to the combined influence of various factors such as the accuracy of the measurement tool, the proficiency of the measurement personnel and visual errors, the obtained thickness data often has certain deviations and it is difficult to accurately reflect the true thickness of the carbon steel protective cover. Summary of the Invention

[0005] The purpose of the present invention is to provide a thickness detection device for carbon steel protective covers to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: a detection table, support columns are arranged on both sides of the top of the detection table, an opening and closing screw rod is arranged inside the support columns, the threads at both ends of the opening and closing screw rod are opposite, both ends of the opening and closing screw rod are slidably connected to the opening and closing screw rod, a card slot is opened in the middle of the inside of the opening and closing screw rod, a support plate is arranged at the bottom end of the card slot, a first spring is connected to the bottom of the support plate, and a moving block is connected to the bottom of the first spring.

[0007] Preferably, multiple sets of rollers are arranged on both sides of the middle part of the detection table. A conveyor belt is sleeved on the rollers. One end of the outermost roller extends out from the outside of the detection table and is inserted into the end of a stepping motor arranged on one side of the detection table. The stepping motor can drive the roller to rotate, so that the conveyor belt starts to move.

[0008] Preferably, a support frame is arranged in the middle of the top of the detection table. A hydraulic cylinder is arranged in the middle of the top of the support frame. A telescopic rod is inserted into the bottom of the hydraulic cylinder. The bottom of the telescopic rod is connected with a monitoring component. The hydraulic cylinder can drive the telescopic rod to extend and retract, driving the monitoring component to lift.

[0009] Preferably, both sides of the baffle are slidably connected with opening and closing screws arranged on the inner sides of the support columns on both sides of the detection table. A knob is arranged in the middle of the opening and closing screw. A limiting rod is arranged on the inner side of the top end of the support frame at the same time. The limiting rod is also slidably connected with the baffle. Turning the knob can make the baffle slide open and close according to the carbon steel protective cover.

[0010] Preferably, connecting rods are arranged on both sides of the top of the monitoring component of the telescopic rod. A first telescopic groove is opened in the middle of the outer side of the connecting rod. A telescopic connecting rod is inserted into the first telescopic groove. A limiting plate is arranged at the inner end of the outer side of the telescopic connecting rod. The limiting plate limits the telescopic connecting rod to prevent the telescopic connecting rod from disengaging from the first telescopic groove.

[0011] Preferably, the outer end of the telescopic connecting rod is inserted into a clamping groove opened in the middle of the inner side of the baffle. Limiting plates are arranged on both sides of the clamping groove located at the top of the support plate. Clamping grooves are opened on both sides of the outer end of the telescopic connecting rod. The limiting plates are clamped in the clamping grooves to connect the telescopic connecting rod with the baffle.

[0012] Preferably, the bottom of the support plate is connected with a moving block through a first spring. The middle of the top of the moving block is connected with a pressing rod. The pressing rod extends out from the top of the support plate. The hydraulic cylinder can drive the telescopic rod to descend, so that the telescopic rod drives the connecting rod and the telescopic connecting rod to descend synchronously, so that the outer end of the telescopic connecting rod presses the pressing rod, and the pressing rod presses the moving block to descend.

[0013] Preferably, a second telescopic groove is opened at the bottom of the moving block. A second spring is arranged in the second telescopic groove. The top of the second spring is connected with the inner wall of the second telescopic groove. The bottom of the second telescopic groove is connected with a telescopic block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] A thickness detection device for a carbon steel protective cover proposed by the present invention. When detecting the thickness of the carbon steel protective cover, first, turn the knob according to the diameter of the carbon steel protective cover, so that the knob drives the opening and closing screw rod to rotate, causing the baffles slidably connected on both sides of the opening and closing screw rod to converge or diverge, making the inner walls of the two baffles closely adhere to the carbon steel protective cover to prevent it from shifting during transmission, improving the stability of transmission. At the same time, the telescopic connecting rod expands and contracts in the first telescopic groove according to the contraction and expansion of the baffle, preventing the connecting rod and the telescopic connecting rod from jamming the contraction and expansion of the baffle. Then, place the carbon steel protective cover between the two baffles through one side of the detection table, start the stepping motor, so that the stepping motor drives the roller shaft to drive the conveyor belt to transmit, and start to convey the carbon steel protective cover. When the carbon steel protective cover reaches directly below the monitoring component, the conveying stops, and the hydraulic cylinder starts to drive the telescopic rod to expand and contract, causing the telescopic rod to drive the monitoring component to descend. The telescopic rod synchronously drives the connecting rod at the top of the monitoring component and the telescopic connecting rod connected to the outside of the connecting rod to descend. When the detectors at the bottom of the monitoring component all contact the surface of the carbon steel protective cover, the telescopic connecting rod simultaneously presses the pressure rod, causing the pressure rod to press down, making the pressure rod press the moving block and the telescopic block elastically connected to the bottom of the moving block to descend synchronously, so that the pressing plate connected to the inner side of the bottom of the telescopic block holds against both sides of the top of the carbon steel protective cover. The hydraulic cylinder continues to drive the telescopic rod to descend, causing the detector head at the bottom of the monitoring component to retract into the monitoring component, and start to detect the thickness of the carbon steel protective cover. At the same time, the telescopic connecting rod continuously presses the pressure rod, causing the telescopic block to press the carbon steel protective cover, making the conveyor belt at the bottom of the carbon steel protective cover closely adhere to the bearing plate arranged in the middle of the detection table, avoiding the conveyor belt driving the carbon steel protective cover to shake, and fixing the carbon steel protective cover through the tension of the second spring in the second telescopic groove. Then, the hydraulic cylinder drives the telescopic rod to contract, retracting the monitoring component. At the same time, the connecting rod and the telescopic connecting rod rise, and the first spring resets the moving block through the contraction force, and the detection is completed.
