Description

Technical Field

[0001] The utility model relates to the technical field of joint testing devices, in particular to a rotary joint working life testing device. Background Art

[0002] Rotary joints can be divided into water pipes, gas pipes, cable pipe joints, etc., which are mostly made of metal as the basic material. After the rotary joints are processed, joint testing equipment is needed to conduct random inspections on the finished products, so as to judge the service life of this batch of rotary joints and ensure the processing quality control of rotary joints.

[0003] After the rotary joint is processed, a joint testing device is needed. Among them, the "rotary joint working life testing device" disclosed by the publication number "CN212963968U" has solved the problem that the existing rotary joints have not been tested for working life. Basically, they are replaced after problems such as inflexible rotation and poor sealing occur during use, which is prone to various disadvantages of danger.

[0004] However, there are still many defects in the actual use of joint testing devices with similar structures. For example, in the prior art, when testing the rotary joint, the rotary joint is prone to metal fatigue under high temperature conditions, resulting in damage to the main body and splashing parts, which may cause injuries to the operator, reducing the reliability of the device and the automation effect of the device. At the same time, after the test operation is completed, the high-temperature test joint is prone to cool and adhere to the inside of the device, requiring the operator to use external equipment to heat and disassemble the test joint. Therefore, it is necessary to design a rotary joint working life test device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a rotary joint working life test device to solve the above problems.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a rotary joint working life test device, comprising a load-bearing plate, a mounting plate is fixedly mounted on one side of the top of the load-bearing plate, and a movable plate is movably mounted on the other side of the top of the load-bearing plate, a protection mechanism for providing safety protection to users is fixedly mounted on one side of the mounting plate, and an auxiliary replacement joint mechanism for assisting the replacement of the rotary joint is fixedly mounted on the other side of the mounting plate;

[0007] The protection mechanism comprises a mounting seat, an electric rod is fixedly mounted on the top of the mounting seat, a bolt plate is fixedly mounted on the output end of the electric rod through a connecting frame, a protection box is fixedly mounted on the bottom of the bolt plate, an industrial camera is fixedly mounted on the top of the protection box through bolts, and moving grooves are opened on both sides of the protection box;

[0008] The auxiliary joint replacement mechanism comprises a docking seat, and screw rods are threadedly installed on both sides of the docking seat.

[0009] Preferably, a limiting rod is fixedly mounted on one side of the front face of the top of the bearing plate, and a sliding sleeve fixedly connected to one side of the movable plate is movably mounted on the outer side of the limiting rod.

[0010] Preferably, a clamping plate is rotatably mounted on one end of the screw rod through a bearing, a plurality of groups of heating tubes are equidistantly mounted inside the clamping plate, and a test joint is clamped and mounted between two groups of clamping plates.

[0011] Preferably, a servo motor is fixedly mounted on one side of the movable plate, and an electric clamp is fixedly mounted on the output end of the servo motor.

[0012] Preferably, a constant-speed motor is fixedly mounted on the back side of the top of the carrier plate, a threaded rod is fixedly mounted on the output end of the constant-speed motor, and a screw sleeve fixedly connected to the movable plate is threadedly mounted on the outer side of the threaded rod.

[0013] Preferably, two groups of mounting parts are fixedly mounted on the outer side of the bearing plate, and fasteners are threadedly mounted on the inner sides of the mounting parts.

[0014] Beneficial Effects

[0015] The utility model provides a rotary joint working life test device. Compared with the prior art, it has the following beneficial effects:

[0016] 1. When the electric clamp drives the rotary joint to be tested to move to one side of the test joint, the electric rod is powered on to drive the bolt plate to move vertically. The bolt plate that moves vertically can drive the protective box to move synchronously, so that the protective box moves down to the outside of the rotary joint to be tested for enclosure. The downward moving protective box can drive the industrial camera to move synchronously. The industrial camera is powered on to monitor the rotary joint to be tested in real time, which replaces manual observation by the operator. The electric rod and the protective box can be used together to realize the function of safety protection for the operator, avoiding the problem of operator injury caused by damage to the main body and splashing parts when the high-temperature rotary joint to be tested rotates, increasing the reliability of the device and the automation of the device.

[0017] 2. The operator rotates the screw rod to drive the clamping plate to move horizontally through the bearing. The clamping plate that moves horizontally can clamp and fix the test joint, which plays a role in clamping and fixing test joints of different specifications. When the test operation is completed, the heating tube is powered on according to the use requirements to generate high temperature and transfer it to the inside of the clamping plate. The temperature can then be transferred to the inside of the test joint through the clamping plate, so that the test joint will not cool down quickly, realizing the function of auxiliary disassembly of the test joint, avoiding the problem that the high-temperature test joint is adhered to the inside of the docking seat, which requires the operator to use external equipment to heat and disassemble the test joint, and facilitating the replacement of the test joint.
