Description

Technical Field

[0001] The utility model is applicable to the technical field of high-temperature chemical pressure vessel processing, and particularly relates to a thickness measuring mechanism for a high-temperature chemical pressure vessel. Background Art

[0002] At present, a high-temperature pressure vessel refers to a closed device that contains gas or liquid and bears a certain pressure.

[0003] However, nowadays, after manufacturing and producing high-temperature pressure vessels, it is necessary to detect the thickness and diameter of the container body to prevent the thickness from being too thin or too thick and affecting the sealing and storage quality of the raw materials inside. When testing the thickness of high-temperature pressure vessels, operators often hold the testing instrument and insert the container testing position into it, so that the testing ends on both sides of the instrument can be attached to the inner wall of the container before the thickness test can be performed. After the operator holds it with one hand, the testing end still needs to be manually adjusted to make it fit the inner wall of the container, and the thickness data cannot be quickly and intuitively tested, resulting in low detection efficiency. Therefore, we propose a thickness measuring mechanism for high-temperature chemical pressure vessels. Utility Model Content

[0004] The main purpose of the utility model is to provide a thickness measuring mechanism for a high-temperature chemical pressure vessel, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A thickness measuring mechanism for a high-temperature chemical pressure vessel comprises a hollow frame, a transmission rod is rotatably mounted on the inner side of the hollow frame through a bearing, and a rotating screw is fixedly mounted on the side of the transmission rod;

[0007] The outer surface of the transmission rod is sleeved with a fixed sleeve through a bearing, the outer end of the rotating screw rod away from the fixed sleeve is sleeved with a transmission sleeve, the bottom surface of the fixed sleeve is fixedly mounted with a first fitting arc plate, and the bottom surface of the transmission sleeve is fixedly mounted with a second fitting arc plate;

[0008] A connecting rod is fixedly installed on the middle surface of one side of the second mating arc plate away from the first mating arc plate, and the connecting rod is slidably installed inside the side of the hollow frame. Two scale plates are fixedly installed on the lower part of one side of the hollow frame, and the connecting rod is located between the scale plates. A connecting sleeve is fixedly sleeved on the top surface of the side of the connecting rod. Connecting frames are fixedly installed on the outer end surfaces of each connecting sleeve, and the connecting frames are slidably installed inside the middle end of the scale plate. A pointer block is fixedly installed on the top surface of the side of each scale plate.

[0009] By adopting the above technical solution, the pointer block is driven to move horizontally on the scale plate surface synchronously through the rotation transmission action of the screw rod on the transmission sleeve combined with the transmission action of the connecting rod, which makes it convenient for the inspector to hold it with one hand for inspection, and allows the inspector to read and process the inspection data intuitively from the top or bottom, thereby improving the thickness inspection efficiency.

[0010] As an optional solution of the technical solution of the present application, a limiting groove is provided inside the top of the hollow frame, and the outer side of the top of the transmission sleeve is slidably inserted into the limiting groove.

[0011] By adopting the above technical solution, the transmission rationality of the entire device is ensured through the limiting transmission effect of the limiting groove on the transmission sleeve.

[0012] As an optional solution of the technical solution of the present application, a pressure sensor is fixedly installed on the surface of one side of the second mating arc plate close to the first mating arc plate, a controller is fixedly installed on the outer top surface of the hollow frame, a servo motor is fixedly installed on the outer surface of the hollow frame, and the side edge of the servo motor transmission shaft is fixedly connected to the outer top surface of the transmission rod through a coupling, the signal output end of the pressure sensor is electrically connected to the signal input end of the controller, and the signal output end of the controller is electrically connected to the signal input end of the servo motor.

[0013] By adopting the above technical solution, the operation automation of the entire device is improved through the interaction and cooperation between the controller and the pressure sensor, and the labor consumption of the operator for operation is further reduced.

[0014] As an optional solution of the technical solution of the present application, a sliding groove is opened inside the middle end of each scale plate, and the connecting frame is slidably installed inside the sliding groove.

[0015] By adopting the above technical solution, the transmission rationality of the entire device is ensured by the guiding sliding action of the sliding groove on the connecting frame.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is a thickness measuring mechanism for a high-temperature chemical pressure vessel, which connects a rotating screw and a servo motor through a transmission rod, so that when the transmission rod rotates, the rotating screw can rotate synchronously, and the rotating sleeve can be driven to move horizontally inside the hollow frame under the rotation transmission effect of the rotating screw on the transmission sleeve, thereby driving the second fitting arc plate to move toward the outside of the first fitting arc plate, and automatically adjusting the spacing between the two groups of fitting arc plates to achieve fitting detection of the thickness of the container barrel wall, and the pointer block is driven to move horizontally on the surface of the scale plate synchronously in combination with the transmission effect of the connecting rod, which is convenient for the detection personnel to hold it with one hand for detection, and allows the detection personnel to intuitively read and process the detection data from above or below, thereby improving the thickness detection efficiency.

A pressure sensor is arranged on the outer side of the second bonding arc plate to detect the pressure information generated by the contact between its side and the outside of the container. Combined with the start and stop control of the servo motor by the controller, the operation automation of the entire device can be improved, and the labor consumption of the operator for operation can be further reduced.
