Description

Technical Field

[0001] The present invention relates to vibration monitoring equipment, and particularly to a portable vibration monitoring device for the surface of steel structures. Background Art

[0002] A steel structure refers to a structural form that can bear and transfer loads, which is formed by connecting steel plates and hot-rolled, cold-bent or welded profiles through connectors. The steel structure system has comprehensive advantages such as light self-weight, factory manufacturing, fast installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, it has unique advantages in the development of "high, large, and light". Globally, especially in developed countries and regions, steel structures are reasonably and widely used in the field of construction engineering. The steel structure industry is usually divided into light steel structures, high-rise steel structures, residential steel structures, space steel structures, and bridge steel structures. The vibration monitoring device for the surface of steel structures is a device used to detect and monitor the vibration conditions on the surface of steel structures. By accurately sensing and measuring the vibration of steel structures, it provides important data support for its condition monitoring, fault warning, and performance optimization.

[0003] The vibration monitoring equipment includes a handheld monitor and a probe. For the convenience of monitoring, a magnet is installed on the probe. However, since the magnet is in contact with the surface of the steel structure, some iron filings on the surface of the steel structure will be adsorbed onto the magnet of the probe. After each monitoring of a position is completed, the iron filings on the magnet need to be cleaned up so that the probe can be in close contact with the surface of the steel structure when monitoring other positions. However, this is rather troublesome and requires waiting until the cleaning is completed before use, which will prolong the monitoring time. And when the probe is not used for a short period of time, the probe cannot be effectively placed. One can only hold the probe and the monitor simultaneously, which is not convenient for carrying. At the same time, the connector of the monitor lacks a protection structure. When the monitor is disconnected from the probe, the connector cannot be shielded and protected. Summary of the Invention

[0004] The main object of the present invention is to provide a portable vibration monitoring device for the surface of steel structures, which can effectively solve the technical problems in the background art.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A portable vibration monitoring device for the surface of steel structures, including a monitor main body, a probe, a moving plate, a supporting block, and a clamping block. A mode switching key is movably installed on one side surface of the monitor main body. A moving plate is movably installed on the rear surface of the monitor main body and near the upper part. A supporting block is movably installed on the front surface of the moving plate and near the upper part. A clamping block is movably installed on the upper surface of the moving plate.

[0007] Further preferably, a limit ring is fixedly sleeved on the surface of the probe near the lower part, a stop ring is fixedly sleeved on the surface of the probe at the lower part, a scraping block is fixedly installed on the surface of the probe and below one side of the limit ring, an arc-shaped mounting sleeve is movably sleeved between the limit ring and the stop ring on the surface of the probe, and an arc-shaped magnetic ring is fixedly embedded in the lower surface of the arc-shaped mounting sleeve.

[0008] Further preferably, the distance between the limit ring and the scraping block is equal to the height of the arc-shaped mounting sleeve, the distance between the head and the tail of the arc-shaped mounting sleeve is equal to the width of the scraping block, the inner diameter of the arc-shaped magnetic ring is larger than the outer diameter of the stop ring, and the outer diameter of the arc-shaped magnetic ring is smaller than the outer diameter of the arc-shaped mounting sleeve.

[0009] Further preferably, longitudinal limit sliding grooves are formed on both sides near the upper part of the rear surface of the monitor main body, a connecting head is fixedly installed on the upper surface of the monitor main body, a wire is fixedly installed on the upper surface of the probe, and one end of the wire is fixed to the connecting head.

[0010] Further preferably, a lifting groove is longitudinally formed in the middle of the front surface of the moving plate, a guide rod is fixedly installed inside the lifting groove, a spring is sleeved on the surface of the guide rod, a rotating groove is formed in the middle of the upper surface of the moving plate, and limit sliding blocks are fixedly installed on both sides near the lower part of the rear surface of the moving plate.

[0011] Further preferably, a rotating block is fixedly installed on the rear part of the lower surface of the buckling block, a groove is formed in the front of the rotating block on the lower surface of the buckling block, a wire clamping groove is formed on the upper surface of the buckling block, the wire clamping groove communicates with the groove, and the width of the wire clamping groove is smaller than the diameter of the groove.

[0012] Further preferably, an embedding groove is formed on the upper surface of the supporting block, a sleeve block is fixedly installed on the rear surface of the supporting block, the sleeve block is sleeved on the surface of the guide rod, and the diameter of the embedding groove is larger than the outer diameter of the arc-shaped mounting sleeve.

[0013] Further preferably, the rotating block is movably embedded in the rotating groove, the buckling block is movably connected with the moving plate through the rotating block, the diameter of the groove is larger than the diameter of the connecting head, the limit sliding block is embedded in the limit sliding groove, and the moving plate is movably connected with the monitor main body through the limit sliding block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, by setting up the cooperation of the monitor body, the moving plate, the clamping block and the supporting block, when the probe is not in use, pull down the supporting block, and the supporting block will compress the spring when pulled down. When the probe is placed between the supporting block and the clamping block, the probe can be limited by the cooperation of the embedding groove and the concave groove. In this way, the probe that is not in use can be placed, which is convenient for carrying the monitor body and the probe. When the probe is disconnected from the connector, pull up the moving plate, then rotate the clamping block so that the clamping block rotates above the connector, and finally pull down the moving plate, then the connector can be covered by the clamping block to avoid damage to the connector.

[0016] By setting up a probe that is easy to clean, after the arc-shaped magnetic ring of the probe adsorbs the iron filings on the surface of the steel structure, the arc-shaped magnetic ring can be moved up, so that the probe can continue to be used to monitor the vibration of other positions of the steel structure, and there is no need to wait until the iron filings on the arc-shaped magnetic ring are cleaned before the probe can be used again. When the monitoring is over, rotate the arc-shaped magnetic ring. At this time, the lower surface of the arc-shaped magnetic ring continuously contacts the scraping block, so that the iron filings adsorbed on the lower surface of the arc-shaped magnetic ring can be scraped together, which is convenient for cleaning.

[0024] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation mode.

[0025] As Figures 1-6 shown, a portable steel structure surface vibration monitoring device includes a monitor main body 1, a probe 2, a moving plate 3, a supporting block 5 and a clamping block 4. A mode switching key 6 is movably installed on one side surface of the monitor main body 1. A moving plate 3 is movably installed on the rear surface of the monitor main body 1 and close to the upper part. A supporting block 5 is movably installed on the front surface of the moving plate 3 and close to the upper part. A clamping block 4 is movably installed on the upper surface of the moving plate 3.

[0026] Further, a limit ring 201 is fixedly sleeved on the surface of the probe 2 and close to the lower part. A stop ring 204 is fixedly sleeved on the surface of the probe 2 and located below. A scraping block 203 is fixedly installed on the surface of the probe 2 and on the lower side of one side of the limit ring 201. An arc-shaped mounting sleeve 202 is movably sleeved between the limit ring 201 and the stop ring 204 on the surface of the probe 2. An arc-shaped magnetic ring 205 is fixedly embedded on the lower surface of the arc-shaped mounting sleeve 202; when the arc-shaped magnetic ring 205 of the probe 2 adsorbs iron filings on the surface of the steel structure, the arc-shaped magnetic ring 205 can be moved upward, and then the arc-shaped magnetic ring 205 is rotated. At this time, the lower surface of the arc-shaped magnetic ring 205 continuously contacts the scraping block 203, so that the iron filings adsorbed on the lower surface of the arc-shaped magnetic ring 205 can be scraped together, which is convenient for cleaning.

[0027] Further, the distance between the limit ring 201 and the scraping block 203 is equal to the height of the arc-shaped mounting sleeve 202. The distance between the head and the tail of the arc-shaped mounting sleeve 202 is equal to the width of the scraping block 203. The inner diameter of the arc-shaped magnetic ring 205 is greater than the outer diameter of the stop ring 204. The outer diameter of the arc-shaped magnetic ring 205 is less than the outer diameter of the arc-shaped mounting sleeve 202; the limit ring 201 can prevent the arc-shaped magnetic ring 205 from moving upward excessively, and the stop ring 204 can prevent the arc-shaped magnetic ring 205 from detaching from the probe 2.

[0028] Further, limiting sliding grooves 101 are longitudinally formed on the rear surface of the monitor main body 1 near both sides above. A connecting head 102 is fixedly installed on the upper surface of the monitor main body 1. A wire is fixedly installed on the upper surface of the probe 2, and one end of the wire is fixed to the connecting head 102.

[0029] Further, a lifting groove 303 is longitudinally formed in the middle of the front surface of the moving plate 3. A guide rod 304 is fixedly installed inside the lifting groove 303. A spring 305 is sleeved on the surface of the guide rod 304. A rotating groove 302 is formed in the middle of the upper surface of the moving plate 3. Limiting sliders 301 are fixedly installed near both sides below the rear surface of the moving plate 3. There is a certain frictional force between the limiting sliders 301 and the limiting sliding grooves 101. In this way, after the moving plate 3 moves up and down, the moving plate 3 will not move up and down due to the shaking of the monitor main body 1.

[0030] Further, a rotating block 403 is fixedly installed at the rear of the lower surface of the clamping block 4. A groove 401 is formed in front of the rotating block 403 on the lower surface of the clamping block 4. A wire clamping groove 402 is formed on the upper surface of the clamping block 4. The wire clamping groove 402 communicates with the groove 401. The width of the wire clamping groove 402 is smaller than the diameter of the groove 401. The groove 401 can be buckled on the upper end of the probe 2 or above the connecting head 102. In this way, the upper end of the probe 2 on the supporting block 5 can be limited, and the unused connecting head 102 can also be shielded and protected.

[0031] Further, an embedding groove 501 is formed on the upper surface of the supporting block 5. A sleeve block 502 is fixedly installed on the rear surface of the supporting block 5. The sleeve block 502 is sleeved on the surface of the guide rod 304. The diameter of the embedding groove 501 is larger than the outer diameter of the arc-shaped mounting sleeve 202. The embedding groove 501 can limit the lower end of the probe 2.

[0032] Further, the rotating block 403 is movably embedded in the rotating groove 302. The clamping block 4 is movably connected to the moving plate 3 through the rotating block 403. The diameter of the groove 401 is larger than the diameter of the connecting head 102. The limiting slider 301 is embedded in the limiting sliding groove 101. The moving plate 3 is movably connected to the monitor main body 1 through the limiting slider 301. The cooperation between the rotating groove 302 and the rotating block 403 can assist the clamping block 3 to rotate flexibly.
