Description

Technical Field

[0001] The utility model relates to the field of gap sheets, in particular to a gap sheet capable of detecting pressure working conditions. Background Art

[0002] The gap sheet is usually made of high-strength, wear-resistant materials with high precision and stability. When installing the gap sheet, it is necessary to ensure that it fits the contact part of the mechanical equipment completely and can accurately transmit pressure or vibration signals. By monitoring the data of the gap sheet, you can understand the working status of the equipment in real time, find problems in time and perform maintenance, thereby extending the service life of the equipment.

[0003] However, the existing gap plate only uses a piezoresistive sensor to detect pressure changes. However, this method will cause its service life to be consumed quickly when the sensor is pressed repeatedly for detection, and it needs to be replaced frequently. Therefore, a gap plate that can detect pressure conditions is needed to solve the above technical problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a gap sheet capable of detecting pressure conditions, which can effectively solve the technical problems in the background technology.

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

[0006] A gap plate capable of detecting pressure working conditions comprises a fixed metal plate, the fixed metal plate being provided with a threaded hole, springs being fixedly connected to both sides of the fixed metal plate at the periphery of the threaded hole, a movable metal plate being fixedly connected to the other end of the spring, a supporting assembly being fixedly connected between the fixed metal plate and the movable metal plate, and a through hole without internal threads corresponding to the threaded hole being provided on the movable metal plate.

[0007] As a further solution of the utility model, the support assembly includes a first H-block fixed on a fixed metal sheet, a first connecting rod is fixedly connected to the first H-block, a first supporting rotating plate is rotatably connected to the first connecting rod, a groove is provided at the end of the first supporting rotating plate, and a second connecting rod is fixedly connected in the groove.

[0008] As a further solution of the utility model, the bottom surface of the movable metal sheet is fixedly connected to a second H-block, the second H-block is fixedly connected to a third connecting rod, the third connecting rod is rotatably connected to a second supporting rotating plate, and the other end of the second supporting rotating plate is rotatably connected to the second connecting rod.

[0009] As a further solution of the utility model, a plurality of displacement sensors are symmetrically fixed on both side walls of the fixed metal sheet.

[0010] As a further solution of the utility model, a plurality of frosted sheets are fixed to the top surface of the movable metal sheet.

[0011] As a further solution of the utility model, a screw is threadedly connected to the fixed metal sheet and passes through the through holes on the movable metal sheets on both sides.

[0012] The beneficial effects of the utility model are as follows:

[0013] The gap sheets are fixed to the components on both sides by screws, so that the frosted sheets on the movable metal sheet are in contact with the surface of the component, thereby increasing friction and avoiding slippage when subjected to force or vibration. When the component generates thrust on the movable metal sheet, the spring contracts, and the spring does not bend or twist under the action of the screw. The movable metal sheet moves toward the fixed metal sheet, and the spacing decreases. The displacement sensor can record the displacement, and then the pressure change trend can be obtained, so that timely measures can be taken to understand the working status. This method can avoid the problem that the piezoresistive sensor is easily damaged and has a serious loss of service life due to the direct extrusion to obtain the pressure change trend.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, a gap sheet capable of detecting pressure working conditions comprises a fixed metal sheet 1, a threaded hole 2 is provided on the fixed metal sheet 1, springs 3 are fixedly connected to both sides of the fixed metal sheet 1 at the periphery of the threaded hole 2, a movable metal sheet 4 is fixedly connected to the other end of the spring 3, a supporting component is fixedly connected between the fixed metal sheet 1 and the movable metal sheet 4, a through hole 5 without internal thread corresponding to the threaded hole 2 is provided on the movable metal sheet 4, and the diameter of the through hole 5 is larger than the diameter of the threaded hole 2 to ensure that when the component generates thrust on the movable metal sheet 4, the movable metal sheet 4 can be smoothly displaced.

[0021] In this embodiment, the support assembly includes a first H-block 6 fixed on the fixed metal sheet 1, a first connecting rod 7 is fixedly connected to the first H-block 6, a first supporting rotating plate 8 is rotatably connected to the first connecting rod 7, a groove 9 is opened at the end of the first supporting rotating plate 8, a second connecting rod 10 is fixedly connected in the groove 9, a second H-block 11 is fixedly connected to the bottom surface of the movable metal sheet 4, a third connecting rod 12 is fixedly connected to the second H-block 11, a second supporting rotating plate 13 is rotatably connected to the third connecting rod 12, and the other end of the second supporting rotating plate 13 is rotatably connected to the second connecting rod 10. When subjected to thrust, the second supporting rotating plate 13 rotates on the third connecting rod 12, and at the same time, the first supporting rotating plate 8 rotates on the first connecting rod 7, so that the support assembly can be contracted when under pressure to synchronize the displacement of the movable metal sheet 4, and can always play a supporting role.

[0022] In this embodiment, a plurality of displacement sensors 14 are symmetrically fixed on both side walls of the fixed metal sheet 1 , and the displacement sensors 14 can record the displacement of the movable metal sheet 4 , thereby knowing the pressure change trend under the working state.

[0023] In this embodiment, a plurality of frosted sheets 15 are fixed to the top surface of the movable metal sheet 4. The frosted sheets 15 can increase the friction between the movable metal sheet 4 and the components, thereby preventing the problem of slippage when subjected to force or vibration.

[0024] In this embodiment, a screw 16 is threadedly connected to the fixed metal sheet 1 and passes through the through holes 5 on the movable metal sheets 4 on both sides. The screw 16 can fix the gap sheet between the two components and limit the contraction trajectory of the spring 3 to avoid the problem of twisting of the spring 3 during the contraction process.

[0025] It should be noted that the utility model is a gap sheet that can detect pressure conditions. When in use, the gap sheet is fixed to the components on both sides by means of a screw 16, so that the frosted sheet 15 on the movable metal sheet 4 contacts the surface of the component, thereby increasing friction and avoiding slippage when subjected to force or vibration. When the component generates a thrust on the movable metal sheet 4, the spring 3 contracts, and under the action of the screw 16, the spring 3 does not bend or twist. The movable metal sheet 4 moves toward the fixed metal sheet 1, and the spacing decreases. The displacement sensor 14 can record the displacement, thereby obtaining the pressure change trend.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
