Description

Technical Field

[0001] This invention relates to a self-calibration device for testing hydraulic equipment, and more particularly to a self-calibration device for testing hydraulic equipment and its molding method, belonging to the field of equipment testing technology. Background Technology

[0002] Hydraulic equipment is commonly found in factories in the construction and machinery industries. It is large in size and has high manufacturing costs. Some hydraulic equipment requires strict location selection to ensure stable operation. It must be placed on a level ground to ensure that the equipment is in a horizontal state and can perform high-precision work.

[0003] Therefore, when selecting a location for the equipment, it is necessary to test and calibrate the equipment and the ground to ensure that the equipment is placed horizontally. However, the existing calibration methods all rely on external auxiliary structures or manual calibration for testing, and the equipment itself does not have a calibration effect. Sometimes, there will be certain errors when performing horizontal calibration.

[0004] Therefore, there is an urgent need to improve the testing and self-calibration of hydraulic equipment in order to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a self-calibration device for testing hydraulic equipment and its testing and calibration method. After being horizontally welded and fixed to the equipment, the equipment has its own horizontal calibration test effect when it is placed in a selected location, without the need to use an external structure for testing and calibration, thereby achieving a self-calibration effect. At the same time, the horizontality of the equipment placement can be directly observed, and the testing and calibration structure is accurate.

[0006] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0007] A hydraulic equipment testing and self-calibration device includes a support plate. A liquid level is provided below the front end face of the support plate. Telescopic rod structures are rotatably provided on both sides of the front end face of the support plate. A welding plate is provided at the end of the telescopic rod structure away from the liquid level. A second telescopic rod structure is provided on the inner side of each telescopic rod structure. The welding plate is also provided at the end of the second telescopic rod structure away from the liquid level.

[0008] A second support plate is vertically arranged on both sides of the lower end face of the support plate. An infrared spotlight is rotatably connected to the upper part of the front end face of the second support plate, with the ray end of the infrared spotlight pointing downwards. A photosensitive sensor is horizontally supported below the front end face of the second support plate. An alarm is arranged in the middle part of the lower end face of the support plate and is connected to the photosensitive sensor.

[0009] Preferably, the liquid level includes a liquid box horizontally disposed below the front end face of the support plate, the liquid box containing a luminous bright liquid, a horizontal line being horizontally disposed on the front end face of the liquid box, and the front end face of the liquid box being transparent explosion-proof glass.

[0010] Preferably, the second telescopic rod structure is the same as the telescopic rod structure. Both sides of the surface of the support plate are provided with first through holes, and a second through hole is provided on the inner side of each first through hole. The second telescopic rod structure is fixedly installed in the second through hole. A first bearing is installed on the inner wall of the first through hole, and the telescopic rod structure is connected to the first bearing.

[0011] Preferably, the telescopic rod structure includes a threaded sleeve and a threaded rod, the length of the threaded rod being greater than that of the threaded sleeve, the threaded rod being threadedly connected to the threaded sleeve, a first rotating handle being provided at the end of the threaded rod away from the welding plate, and a positioning mechanism being provided above the telescopic rod structure.

[0012] Preferably, the positioning mechanism includes an auxiliary plate horizontally disposed above the side of the support plate away from the liquid level and a second threaded rod. The auxiliary plate has a threaded hole that is threadedly connected to the second threaded rod. The upper end face of the threaded sleeve has an insertion hole for insertion into the second threaded rod. The upper end of the second threaded rod is provided with a second rotating handle.

[0013] Preferably, a connecting rod is provided above the front end face of the second support plate, a second bearing is connected to the connecting rod, and the infrared spotlight is located below the second bearing.

[0014] Preferably, a counterweight is provided on the lower end face of the second bearing, and the infrared spotlight is fixedly disposed on the lower end face of the counterweight. The infrared spotlight is a rechargeable spotlight.

[0015] Preferably, a second auxiliary plate is horizontally disposed below the front end face of the second support plate, and the photosensor is disposed on the upper end face of the second auxiliary plate.

[0016] Preferably, both the photosensor and the alarm have a charging structure, and the irradiation end of the infrared spotlight is located directly above the photosensor.

[0017] A test calibration method for a hydraulic equipment test self-calibration device includes the following steps:

[0018] S1: When the device and equipment are fixedly installed, the welding plate is attached to the surface of the equipment. When the device and equipment are welded, the device can be accurately welded to the equipment horizontally by observing the liquid level and using structures such as infrared lamps, alarms and light sensors.

[0019] S2: After the device is welded, it is in a fixed state with the equipment. When the equipment is placed in a selected location, it is brought into contact with the ground. When the equipment is tilted, the bright liquid inside the liquid box will not be horizontal. At the same time, the infrared spotlight, the alarm, and the photosensitive sensor are turned on. During the tilting process, the infrared spotlight with counterweight is prevented from tilting and remains perpendicular to the ground. However, the photosensitive sensor below, being fixedly connected, will tilt. Therefore, the light emitted by the infrared spotlight will not come into contact with the photosensitive sensor, resulting in the photosensitive sensor not receiving light and failing to reach the light setting value. As a result, the alarm will sound to prompt the staff to make adjustments.

[0020] S3: During the adjustment process, if the liquid inside the liquid box is level with the horizontal line, and the light emitted by the infrared spotlight comes into contact with the light sensor, causing the light sensor to receive the light and reach the light setting value, the alarm will stop, thus ensuring that the equipment is in a completely level state.

[0021] This invention has at least the following beneficial effects:

[0022] 1. By utilizing a liquid level, photosensor, alarm, and infrared spotlight, the device is horizontally fixed on the equipment. When the liquid inside the liquid tank is level with the water level, and the infrared spotlight emits light that comes into contact with the photosensor, the sensors receive the light and reach the set light level, thus preventing the alarm from sounding. This indicates that the equipment is currently in a level state, ensuring that it is perfectly level. This allows the equipment to perform self-calibration testing without the need for external structures, achieving a self-calibration effect. Furthermore, the device's levelness can be directly observed, and the use of multiple level calibration structures ensures accurate testing and calibration.

[0023] 2. The two telescopic rod structures and the two second telescopic rod structures have corresponding telescopic adjustment effects, which can drive the welding plate to adjust its position. This allows for corresponding adjustments according to the needs of the equipment installation surface, improving the adaptability of the device and making it suitable for different installation surfaces of different equipment.

Detailed Implementation

[0033] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0034] like Figures 1-7 As shown, the novel pipeline self-calibration device provided in this embodiment includes a support plate 1. A liquid level 2 is provided below the front end face of the support plate 1. The liquid level 2 includes a liquid box 201 horizontally arranged below the front end face of the support plate 1. The liquid box 201 contains a bright liquid that emits light. The bright liquid that emits light, together with the horizontal line 202, can more clearly and intuitively show the level of the liquid. The horizontal line 202 is arranged horizontally on the front end face of the liquid box 201. The front end face of the liquid box 201 is made of transparent explosion-proof glass.

[0035] Telescopic rod structures 3 are rotatably mounted on both sides of the front end face of the support plate 1. A welding plate 4 is mounted on the end of the telescopic rod structure 3 furthest from the liquid level 2. A second telescopic rod structure 5 is mounted on the inner side of each telescopic rod structure 3, and a welding plate 4 is also mounted on the end of the second telescopic rod structure 5 furthest from the liquid level 2. Furthermore, the second telescopic rod structure 5 has the same structure as the telescopic rod structure 3. First through holes 10 are opened on both sides of the surface of the support plate 1. A second through hole 11 is opened on the inner side of each first through hole 10. The second telescopic rod structure 5 is fixedly engaged within the second through hole 11. A first bearing 12 is engaged within the inner wall of the first through hole 10. The telescopic rod structure 3 is engaged and connected with the first bearing 12. When welding and installing the equipment, first adjust one of the telescopic rod structures 3 so that the welding plate 4 on its upper part is welded and fixed to the surface of the equipment. Since the first bearing 12 is provided, after fixing one end of the device, the other end can be rotated and adjusted to adjust the welding plate 4 on the other end of the telescopic rod structure 3 to a state of contact and contact with the surface of the equipment. Then, by observing the liquid level 2 and using the infrared spotlight 7, alarm 9 and photosensitive sensor 8, keep both ends of the device in a horizontal state before welding. This allows the device to be accurately welded to the equipment horizontally. Finally, adjust the welding plate 4 at one end of the two second telescopic rod structures 5 so that it contacts the surface of the equipment and then weld and fix it.

[0036] Furthermore, the telescopic rod structure 3 includes a threaded sleeve 301 and a threaded rod 302. The length of the threaded rod 302 is greater than that of the threaded sleeve 301. The threaded rod 302 and the threaded sleeve 301 are threadedly connected. A first rotating handle 13 is provided at the end of the threaded rod 302 away from the welding plate 4. The two telescopic rod structures 3 and the two second telescopic rod structures 5 can be adjusted according to the requirements of the equipment mounting surface. Since the mounting surface of some equipment is not a flat surface, the first rotating handle 13 is used to drive the threaded rod 302 to rotate inside the threaded sleeve 301, thereby adjusting the position of the welding plate 4 at the other end, ensuring that multiple welding plates 4 can be welded and fixed to the irregular surface on the equipment. A positioning mechanism 14 is also provided above the telescopic rod structure 3.

[0037] Furthermore, the positioning mechanism 14 includes an auxiliary plate 1401 horizontally positioned above the support plate 1 on the side away from the liquid level 2, and a second threaded rod 1402. The auxiliary plate 1401 has a threaded hole 1403 that is threadedly connected to the second threaded rod 1402. The upper end face of the threaded sleeve 301 has an insertion hole 1404 for inserting into the second threaded rod 1402. The upper end of the second threaded rod 1402 is provided with a second rotating handle 15, which facilitates the rotation of the second threaded rod 1402. The positioning mechanism 14 is used for positioning the telescopic rod structure 3. When the telescopic rod structure 3 is adjusted, since the threaded sleeve 301 is stuck inside the first bearing 12, it is necessary to fix the bottom end of the threaded sleeve 301 into the insertion hole 1404 of the threaded sleeve 301 to prevent the threaded rod 302 from rotating normally inside the threaded sleeve 301.

[0038] A second support plate 6 is vertically installed on both sides of the lower end face of the support plate 1. An infrared spotlight 7 is rotatably connected to the upper part of the front end face of the second support plate 6. The ray end of the infrared spotlight 7 points downward. A photosensitive sensor 8 is horizontally supported below the front end face of the second support plate 6. An alarm 9 connected to the photosensitive sensor 8 is installed in the middle part of the lower end face of the support plate 1.

[0039] Among them, a connecting rod 16 is provided above the front end face of the second support plate 6, and a second bearing 17 is connected to the connecting rod 16. An infrared spotlight 7 is provided below the second bearing 17.

[0040] Furthermore, a counterweight 18 is provided on the lower end face of the second bearing 17, and an infrared spotlight 7 is fixedly installed on the lower end face of the counterweight 18. The infrared spotlight 7 is a rechargeable spotlight.

[0041] Furthermore, a second auxiliary plate 19 is horizontally arranged below the front end face of the second support plate 6, and a light sensor 8 is arranged on the upper end face of the second auxiliary plate 19; both the light sensor 8 and the alarm 9 have a charging structure, and the irradiation end of the infrared spotlight 7 is located directly above the light sensor 8.

[0042] A test calibration method for a hydraulic equipment test self-calibration device includes the following steps:

[0043] S1: When the device and equipment are fixedly installed, the welding plate 4 is attached to the surface of the equipment. When the device and equipment are welded, the device can be accurately welded to the equipment by observing the liquid level 2 and by using the infrared lamp 7, alarm 9 and light sensor 8.

[0044] S2: After the device is welded, it is in a fixed state with the equipment. When the equipment is placed, it is placed in contact with the ground. When the equipment is tilted, the bright liquid inside the liquid box 201 will not be horizontal with the horizontal line 202. At the same time, the infrared spotlight 7, the alarm 9 and the light sensor 8 are turned on. During the tilting process, the infrared spotlight 7 with the counterweight 18 will not tilt with the second bearing 17 and will always be perpendicular to the ground. Since the light sensor 8 below is fixed, it will tilt with the infrared spotlight 7. Therefore, the light emitted by the infrared spotlight 7 will not come into contact with the light sensor 8, so the light sensor 8 will not receive light and will not reach the light setting value. As a result, the alarm 9 will sound an alarm to prompt the staff to make adjustments.

[0045] S3: During the adjustment process, if the liquid inside the liquid box 201 is horizontal with the horizontal line 202, and the light emitted by the infrared spotlight 7 comes into contact with the light sensor 8, the light sensor 8 receives the light and reaches the light setting value, so the alarm 9 will stop alarming, thus ensuring that the equipment is in a completely horizontal state.

This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" as used throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to."
