TECHNICAL FIELD

[0001] The utility model relates to sensor installation technical field, concretely relates to a kind of infrared overtemperature monitoring protection's quick test device. BACKGROUND

[0002] Belt conveyor is a kind of continuous conveying equipment widely used in various trades, which includes drum in contact with conveying belt, and drives conveying belt to run by friction force. During the operation of drum, it may cause temperature to be too high due to various reasons, such as mechanical reasons such as excessive load causing motor and drum load to increase, improper installation and maintenance causing friction to increase and rotational resistance to increase, electrical reasons such as motor failure and electrical control problems causing abnormal current, and environmental reasons such as excessive environmental temperature and dust accumulation affecting heat dissipation. Excessive temperature of drum may cause various adverse consequences such as damage to structural integrity of drum, damage to rotating parts of drum, fire, product quality decline, and unstable operation of belt conveyor. Therefore, it is of great significance to implement overtemperature protection for drum.

[0003] In the prior art, an infrared temperature sensor is usually selected to protect the drum from overtemperature. The infrared temperature sensor can measure the surface temperature of the drum without direct contact, and can quickly respond to temperature changes. In addition, it has small volume, light weight, flexible installation position, and can measure temperature by aiming at the surface of the drum. It is easy to install and has low maintenance cost.

[0004] To verify whether the infrared temperature sensor can measure the surface temperature and changes of the drum in time and accurately during actual operation of the drum, tests are usually carried out. However, the sensor is usually fixed on the rack of the belt conveyor, and the emission hole is directly opposite the surface of the drum. This installation method causes the heat source to be extended to the emission hole of the sensor multiple times during the test, and the heat source is difficult to be stably aimed at the emission hole of the sensor, resulting in low test efficiency. UTILITY MODEL CONTENTS

[0005] To solve the technical problem that the fixed installation of the infrared temperature sensor causes the heat source to be extended to the emission hole of the sensor multiple times during the test, and the heat source is difficult to be stably aimed at the emission hole of the sensor, resulting in low test efficiency, the utility model provides a kind of infrared overtemperature monitoring protection's quick test device.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The utility model provides a kind of infrared over-temperature monitoring protection's quick test device, including mounting bracket, mounting bracket includes rotating rod, the first end of rotating rod is used to install infrared sensor, the second end of rotating rod is rotatably installed in the belt frame of belt conveyor side through rotating shaft, rotating shaft is vertically arranged;Rotating rod is connected with the first end of pull rod, the second end of pull rod is detachably connected with belt frame, so that the second end of pull rod and belt frame have two connection states of complete connection and disconnection, the second end of pull rod and the belt frame of rotating shaft are located in the same side of belt conveyor;The second end of pull rod and belt frame are in the connection state of complete connection, rotating rod is relatively fixed with belt frame;The second end of pull rod and belt frame are in the connection state of disconnection, rotating rod can rotate around rotating shaft.

[0008] With the above structure scheme, by rotatably installing rotating rod on belt frame, and setting pull rod detachably connected with belt frame, the switching between the two states of fixing and rotating of rotating rod is realized.In normal monitoring, rotating rod is fixed, to ensure that infrared sensor stably monitors the temperature of drum surface;In test, rotating rod is rotatable, to facilitate moving away sensor, so that heat source can easily and stably aim at sensor emission hole, solve the problem that heat source is difficult to aim in traditional test, significantly improve test efficiency.

[0009] As a preferred implementation of a kind of infrared over-temperature monitoring protection's quick test device, the second end of pull rod and belt frame are in the connection state of complete connection, rotating rod and belt frame are in the state of mutual perpendicular.

[0010] With the above structure scheme, when rotating rod and belt frame are perpendicular, infrared sensor emission hole installed in the first end of rotating rod can accurately face drum surface, to ensure that sensor can accurately obtain temperature information of drum surface in normal monitoring process, improve the accuracy and reliability of temperature measurement.

[0011] As a preferred implementation of a kind of infrared over-temperature monitoring protection's quick test device, rotating rod is rotatably connected with the first end of pull rod, the second end of pull rod and belt frame are in the connection state of disconnection, rotating rod and pull rod can relatively rotate with a vertical direction as the axis of rotation.

[0012] With the above structure scheme, the relative rotation function between rotating rod and pull rod further increases the activity flexibility of rotating rod.In test process, operator can more conveniently adjust the position and angle of rotating rod, so that sensor emission hole can better avoid drum, provide larger operating space for the placement of heat source, to more efficiently complete the operation of heat source aiming at sensor emission hole, improve the convenience of test.

[0013] In a preferred implementation of a rapid testing device for infrared over-temperature monitoring and protection, the pull rod is a steel bar, the first end of the pull rod is bent into a first connecting ring, a first nut is welded to the upper surface of the rotating rod, the axial direction of the first nut is vertically set, the first connecting ring is sleeved on the outer circumference of the first nut, and the inner diameter of the first connecting ring is larger than the outer diameter of the first nut.

[0014] The above structural design, using steel bars as tie rods, offers low cost and provides sufficient strength and toughness. The fit between the first connecting ring and the first nut achieves both rotational connection between the rotating rod and the tie rod and ensures connection stability. The larger inner diameter design allows the first connecting ring to rotate smoothly around the outer circumference of the first nut, providing a reliable structural foundation for the relative rotation of the rotating rod and the tie rod. Furthermore, this structure is simple to manufacture and easy to process, facilitating the production and maintenance of the device.

[0015] In a preferred implementation of a rapid testing device for infrared over-temperature monitoring and protection, the second end of the pull rod is bent into a second connecting ring, a second nut is welded to the upper surface of the belt frame, the axial direction of the second nut is vertical, the second connecting ring is sleeved on the outer circumference of the second nut, and the inner diameter of the second connecting ring is larger than the outer diameter of the second nut.

[0016] With the above structural design, the engagement of the second connecting ring and the second nut enables a detachable connection between the pull rod and the belt frame. This connection method is simple to operate and facilitates quick switching between experimental and normal monitoring states. The larger inner diameter design ensures that the second connecting ring can be more easily attached to the outer circumference of the second nut, making the connection or disconnection of the pull rod with the belt frame smoother and improving the ease of use of the device.

[0017] In a preferred implementation of a rapid testing device for infrared over-temperature monitoring and protection, a fixing clamp is installed at the first end of the rotating rod, which is used to hold the infrared sensor.

[0018] The above structural design provides a stable mounting method for the infrared sensor using a fixing clip. By holding the sensor in place, it ensures that the sensor will not loosen or shift during the rotation of the rotating rod, guaranteeing the stability of the sensor during monitoring and testing, thereby improving the accuracy of temperature measurement and the reliability of test results. It also facilitates the maintenance and replacement of the infrared sensor.

[0019] As a preferred implementation of a rapid testing device for infrared over-temperature monitoring and protection, the fixing clamp includes a U-shaped main body, one side of which has a threaded hole that is threadedly connected to a screw.

[0020] With the above structural design, the U-shaped body provides a suitable placement space for the sensor, while the threaded connection between the screw and the threaded hole allows the clamping force on the sensor to be adjusted by rotating the screw. This adjustable clamping method can accommodate infrared sensors of different sizes and shapes, enhancing the versatility of the device and reducing the hassle of replacing mounting components due to different sensor specifications.

[0021] In a preferred implementation of a rapid testing device for infrared over-temperature monitoring and protection, one end of the screw extending into the main body is connected to an elastic element.

[0022] With the above structural design, the elastic element provides cushioning and protection. When using a screw to clamp the sensor, the elastic element prevents the screw from applying excessive pressure directly to the sensor, thus preventing damage due to excessive clamping force. Simultaneously, the elastic element better conforms to the sensor surface, improving clamping stability and ensuring the sensor maintains a good installation condition throughout device operation.

[0033] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Please see Figures 1-5 This embodiment proposes a rapid testing device for infrared over-temperature monitoring and protection, including a mounting frame, which includes a rotating rod 1 and a pull rod 5.

[0035] A fixing clip 10 is installed at the first end of the rotating rod 1. The fixing clip 10 is used to hold the infrared sensor 2. The fixing clip 10 includes a U-shaped body 101. A threaded hole is opened on one side of the body 101. The threaded hole is threadedly connected to a screw 102. One end of the screw 102, which extends into the body 101, is connected to an elastic element 103. The second end of the rotating rod 1 is rotatably mounted on a belt frame 4 on the side of the belt conveyor via a rotating shaft 3. The rotating shaft 3 is vertically arranged. In this embodiment, the belt frame 4 refers to the frame of the belt conveyor that is arranged parallel to the length direction of the conveyor belt on both sides.

[0036] The tie rod 5 is a steel bar. The first end of the tie rod 5 is bent into a first connecting ring 6. A first nut 7 is welded to the upper surface of the rotating rod 1. The first nut 7 is vertically arranged in the axial direction. The first connecting ring 6 is sleeved on the outer circumference of the first nut 7. The inner diameter of the first connecting ring 6 is larger than the outer diameter of the first nut 7. The first connecting ring 6 can rotate smoothly on the outer circumference of the first nut 7, so that the first end of the tie rod 5 is rotatably connected to the rotating rod 1.

[0037] The second end of the pull rod 5 is located on the belt frame 4 on the same side of the belt conveyor as the rotating shaft 3. The second end of the pull rod 5 is bent into a second connecting ring 8. A second nut 9 is welded to the upper surface of the belt frame 4. The axial direction of the second nut 9 is vertical. The second connecting ring 8 is sleeved on the outer circumference of the second nut 9. The inner diameter of the second connecting ring 8 is larger than the outer diameter of the second nut 9. The second connecting ring 8 can be more easily attached to the outer circumference of the second nut 9, so that the second end of the pull rod 5 can be detachably connected to the belt frame 4. That is, the second end of the pull rod 5 and the belt frame 4 have two connection states: fully connected and disconnected.

[0038] When the second end of the pull rod 5 is connected to the belt frame 4, the rotating rod 1 is fixed relative to the belt frame 4 and is perpendicular to it. When the second end of the pull rod 5 is disconnected from the belt frame 4, the rotating rod 1 can rotate around the rotating shaft 3.

[0039] Working principle:

[0040] The infrared sensor 2 is placed in the fixing clamp 10 at the first end of the rotating rod 1. The U-shaped body 101 of the fixing clamp 10 provides a space to accommodate the infrared sensor 2. Since the screw 102 is threadedly connected to the threaded hole on the side of the body 101, the screw 102 will move into the body 101 along the threaded hole by rotating the screw 102. The elastic element 103 connected to the end of the screw 102 that extends into the body 101 will contact the infrared sensor 2. The elastic element 103 can play a buffering role to avoid damage to the infrared sensor 2 during clamping, and at the same time, it can better adapt to infrared sensors 2 of different shapes and sizes, so as to achieve a stable clamping of the infrared sensor 2.

[0041] The second end of the rotating rod 1 is rotatably mounted on the belt frame 4 on the side of the belt conveyor via a vertically set rotating shaft 3, allowing the rotating rod 1 to rotate around the rotating shaft 3. The first end of the pull rod 5 is connected to the rotating rod 1, and the second end is detachably connected to the belt frame 4. The second end of the pull rod 5 and the rotating shaft 3 are located on the same side of the belt frame 4 of the belt conveyor. Specifically, the pull rod 5 is a steel bar, the first end of which is bent into a first connecting ring 6 and fitted around the outer circumference of a first nut 7 welded vertically in the axial direction on the upper surface of the rotating rod 1. The inner diameter of the first connecting ring 6 is larger than the outer diameter of the first nut 7. The second end of the pull rod 5 is bent into a second connecting ring 8 and fitted around the outer circumference of a second nut 9 welded vertically in the axial direction on the upper surface of the belt frame 4. The inner diameter of the second connecting ring 8 is larger than the outer diameter of the second nut 9. This connection method ensures both the flexibility of the connection and facilitates the detachable function.

[0042] When the second end of the pull rod 5 is connected to the belt frame 4, the rotating rod 1 and the belt frame 4 are relatively fixed, and at this time the rotating rod 1 and the belt frame 4 are perpendicular to each other. In this state, the infrared sensor 2 installed at the first end of the rotating rod 1 faces the surface of the roller 11, and can monitor the surface temperature of the roller 11 normally, and obtain the temperature and changes of the surface of the roller 11 in real time, so as to verify whether the infrared sensor 2 can measure the temperature in a timely and accurate manner during the actual operation of the roller 11.

[0043] When testing is required, disconnect the second end of the pull rod 5 from the belt frame 4. At this time, the rotating rod 1 can rotate around the rotating shaft 3. Simultaneously, because the rotating rod 1 is rotatably connected to the first end of the pull rod 5, the rotating rod 1 and the pull rod 5 can rotate relative to each other around a vertical axis. The operator can rotate the rotating rod 1 to move the infrared sensor 2 away from the surface of the roller 11, and then easily and stably place the heat source at the emission port of the infrared sensor 2. This avoids the previous problem of repeatedly extending the heat source to the emission port of the infrared sensor 2 and the difficulty in achieving stable alignment, greatly improving testing efficiency. After the test, rotate the rotating rod 1 back to its original position, and then reconnect the second end of the pull rod 5 to the belt frame 4, restoring the device to normal monitoring status.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
