Description

Technical Field

[0001] This utility model relates to the field of temperature isostatic pressing equipment technology, and more specifically, to a device for detecting the deformation of an ultra-high pressure load-bearing frame. Background Technology

[0002] Ultra-high pressure isostatic pressing (UHPP) or thermostatic pressing (HPP) equipment is becoming increasingly widespread in daily applications, leading to greater emphasis on its safety monitoring. Monitoring the load-bearing frame allows for real-time monitoring of the equipment's health status. During operation or under load, the load-bearing frame of UHPP or HPP equipment deforms due to the thrust of the chamber cover. However, most existing UHPP or HPP equipment does not monitor the elongation or deformation of the load-bearing frame in the length direction under load.

[0003] Existing publication number CN203757302U discloses a vertical ultra-high pressure bearing frame structure, including a pressure bearing frame and a high-pressure chamber. Semicircular blocks are installed between the pressure bearing frame and the high-pressure chamber, and plugs are installed at both ends of the high-pressure chamber. A pad is installed between the semicircular blocks and the plugs, with one end face of the pad being flat and the corresponding other end face being a concave spherical surface. The advantages are: unique structure, convenient use, good alignment between the plugs and the pad, uniform stress distribution, effectively extending the service life of the equipment and improving its economic efficiency. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: Most existing ultra-high pressure isostatic pressing or thermostatic pressing equipment does not monitor the elongation or deformation of the load-bearing frame in the length direction under load. This indicates insufficient safety monitoring of the equipment, potentially leading to safety hazards or risks. Therefore, a device for detecting the deformation of an ultra-high pressure load-bearing frame is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for detecting the deformation of an ultra-high pressure load-bearing frame, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for detecting the deformation of an ultra-high pressure load-bearing frame, comprising a connecting rod, a load-bearing frame, a load-bearing component, and a fixed end; the surface of the load-bearing frame is provided with a connecting rod and a fixed end; one end of the connecting rod is fixedly connected to the fixed end; the fixed end is connected to the load-bearing frame; and the load-bearing component is fixedly connected to the surface of the load-bearing frame.

[0006] Preferably, the bottom of the connecting rod is provided with a first bracket, a second bracket, and a third bracket; the pre-set holes on the surface of the first bracket, the second bracket, and the third bracket are clearance fits with the connecting rod.

[0007] Preferably, a displacement sensor is provided at the other end of the connecting rod; the end of the connecting rod is in contact with the probe of the displacement sensor C.

[0008] Preferably, beam A is fixedly connected to the top of the load-bearing frame; beam B is provided at the bottom of beam A; and beam B is fixedly connected to the bottom of the load-bearing frame.

[0009] The technical effects and advantages of this utility model are as follows: 1. Compared with the existing technology, the deformation detection device of the ultra-high pressure load frame has a connecting rod installed on the load frame along the length direction. One end of the connecting rod is fixed and the other end is in a free state along the axis and is in contact with the displacement sensor. This solution is reliable, simple and easy to implement.

[0010] 2. Compared with existing technologies, this ultra-high pressure load-bearing frame deformation detection device maintains a relatively fixed, constant elongation of beams A and B under rated pressure, indicating that the device is operating within safe limits. If this value increases significantly, the device will issue an alarm, suggesting that it may be operating in an unsafe condition and requiring investigation. By installing a length deformation detection device on the load-bearing frame, the deformation can be directly measured and displayed, providing a direct judgment on whether the operation is normal or not.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1 As attached Figure 1 The device for detecting the deformation of an ultra-high pressure load-bearing frame includes a connecting rod 5, a load-bearing frame, and a fixed end 1. The device is characterized in that: the surface of the load-bearing frame is provided with the connecting rod 5 and the fixed end 1; one end of the connecting rod 5 is fixedly connected to the fixed end 1; the fixed end 1 is connected to the load-bearing frame; and the load-bearing component is fixedly connected to the surface of the load-bearing frame.

[0015] Wherein: When the force-bearing frame is under the action of force, its force-bearing components will extend to both ends. The amount of extension is proportional to the magnitude of the pressure. One end of the connecting rod 5 is connected to the fixed end 1 and fixed to the force-bearing frame. When the force-bearing components extend, the end of the connecting rod 5 will move towards the fixed end 1.

[0016] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figure 1 As shown below, see details: In a preferred embodiment, the bottom of the connecting rod 5 is provided with a first bracket 2, a second bracket 3, and a third bracket 4; the pre-set holes on the surfaces of the first bracket 2, the second bracket 3, and the third bracket 4 are clearance fits with the connecting rod 5; wherein the first bracket 2, the second bracket 3, and the third bracket 4 serve as supports, and when the connecting rod 5 moves toward the fixed end 1, it will slide in the slots opened on the surfaces of the first bracket 2, the second bracket 3, and the third bracket 4.

[0017] In a preferred embodiment, a displacement sensor is provided at the other end of the connecting rod 5; the end of the connecting rod 5 is in contact with the probe of the displacement sensor C. When the end of the connecting rod 5 moves toward the fixed end 1, the displacement sensor measures the value of the movement, which is then sent to the equipment PLC for processing and displayed on the operation screen.

[0018] In a preferred embodiment, the load-bearing components include beam A and beam B; beam A is fixedly connected to the top of the load-bearing frame; beam B is located at the bottom of beam A; and beam B is fixedly connected to the bottom of the load-bearing frame. When the equipment operates under rated pressure, the amount of force extension of beams A and B is relatively fixed, a constant, indicating that the equipment is operating within a safe range. If this value increases on any given day, the equipment will issue an alarm, indicating that the equipment may be operating in an unsafe state, and the cause needs to be investigated.

[0019] In this embodiment, the displacement sensor and other devices are commercially available and known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them and have not made any structural or functional improvements. We will not go into details here.

[0020] The working process of this utility model is as follows: During operation, under the action of force, beams A and B of the load-bearing frame will extend. The amount of extension is directly proportional to the magnitude of the pressure. When beams A and B extend under force, the ends of the connecting rods will move towards the fixed end. At this time, the displacement sensor will measure the value of the movement. The displacement sensor can detect the distance of movement and measure the value of the movement. This value is sent to the equipment PLC for processing and displayed on the operation screen. When the equipment is working under rated pressure, the amount of extension of beams A and B is relatively fixed, which is a constant, indicating that the equipment is working within a safe range. If this value increases on any given day, the equipment will issue an alarm, indicating that the equipment may be operating in an unsafe state and the cause needs to be investigated. The above is the working principle of this ultra-high pressure load-bearing frame deformation detection device.
