Description

Technical Field

[0001] The present invention relates to the technical field of vibration detection, and in particular to a vibration detection device for mining machinery. Background Art

[0002] During the process of mineral extraction, due to various mining operations being carried out frequently, both the mechanical equipment in the mine shaft and the mine shaft itself will generate mechanical vibrations. From a safety perspective, the mechanical vibrations should be controlled within a reasonable range, which requires the use of a detection device to detect the mechanical vibrations. When the existing detection devices are detecting, the number of vibration directions detected simultaneously is limited, and it is difficult to detect the vibrations in six directions of front, back, left, right, up, and down simultaneously. Moreover, the degree of vibration is difficult to intuitively display, resulting in low detection efficiency, highlighting the deficiencies of the existing technology. Summary of the Invention

[0003] The purpose of the present invention is to provide a vibration detection device for mining machinery to solve the technical problem of low detection efficiency of the existing detection devices.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions: A vibration detection device for mining machinery includes an upper support seat made of a transparent material. The upper support seat is penetrated by straight diffusion channels in the front-back direction, left-right direction, and up-down direction, and a spherical cavity is formed in the middle part. At both ends of each diffusion channel close to the outer wall of the upper support seat, parallel stepped optical holes are respectively opened. A direction control valve is installed in each stepped optical hole. Each diffusion channel is connected through the spherical cavity in the middle. A stepped screw hole is opened in the upper right front part of the upper support seat. The bottom of the stepped screw hole is connected to the spherical cavity. The upper part of the stepped screw hole is coaxially and hermetically threadedly connected with an inner hexagonal support cylinder, and a syringe is installed. The bottom of the inner hexagonal support cylinder is hermetically sealed and fixed with a rubber stopper. The syringe barrel is inserted into the upper part of the stepped screw hole, and the needle can penetrate through the rubber stopper and be inserted into the gap between the bottom of the stepped optical hole and the spherical cavity and extend to the virtual center of the spherical cavity. A transparent, flowing, non-explosive and non-flammable liquid medium A is stored in the diffusion channels and the spherical cavity together. A colored, flowing, non-explosive and non-flammable liquid medium B is stored in the syringe. The liquid medium A and the liquid medium B have the same density and do not undergo a biochemical reaction, are not flammable or explosive after mixing. The upper support seat is equipped with a fastening mechanism.

[0005] On the basis of the above technical solution, six groups of grating sensors are fixed inside the upper support seat. Each group of grating sensors consists of a transmitter and a receiver. The two through end parts of each diffusion channel respectively correspond to a group of grating sensors. The transmitter and receiver in the grating sensor are arranged oppositely on the radial two sides with respect to the diffusion channel. Each group of grating sensors is commonly electrically connected to a controller, and the controller is electrically connected to a storage battery, a display screen and a control button.

[0006] On the basis of the above technical solution, the control valve is a one-way valve. The one-way valve includes a lower valve core, a valve hole and a compression spring. The lower valve core is slidably connected in parallel with the stepped light hole, and a compression spring is jointly fixed to the end part far away from the outer wall of the upper support seat and the stepped surface of the stepped light hole close to the spherical cavity. The valve hole penetrates through the outer wall of the lower valve core along the sliding direction, and has a tendency to slide along the stepped light hole and away from the spherical cavity under the elastic repulsive force of the compression spring. The valve hole can be hermetically sealed and blocked by the stepped surface of the stepped light hole close to the outer wall of the upper support seat under the elastic repulsive force of the compression spring.

[0007] On the basis of the above technical solution, the upper support seat is also provided with a detachable cleaning mechanism. The cleaning mechanism includes a mounting seat, side connecting pipes, a main connecting pipe, a docking cylinder, a screw cylinder, a thimble and a two-way pump. Four vertical side connecting pipes and a vertical main connecting pipe are fixed to the bottom end of the mounting seat. The bottom parts of the side connecting pipes are respectively fixedly communicated with horizontal docking cylinders. The docking cylinders are respectively docked with the diffusion channels in the front-back direction and left-right direction of the upper support seat. The docking cylinders are respectively coaxially and hermetically threadedly connected with screw cylinders. The end parts of the screw cylinders far away from the upper support seat are closed, and the end parts close to the upper support seat penetrate through. The screw cylinders penetrate through in the radial direction in the middle and are communicated with the main connecting pipe, and can be hermetically inserted into the through parts of the diffusion channels. The screw cylinder can push the lower valve core so that the screw cylinder is communicated with the spherical cavity through the valve hole. The main connecting pipe is vertically docked with the upper part of the diffusion channel in the up-down direction of the upper support seat, and a vertically penetrating thimble is fixed to the bottom end of the inner wall. The thimble can push down the one-way valve in the diffusion channel docked with the main connecting pipe. The mounting seat is provided with a two-way pump. The two-way pump is electrically connected to the controller, and one of its ports is simultaneously communicated with each sub-connecting pipe and the main connecting pipe.

[0008] On the basis of the above technical solution, the cleaning mechanism further includes a water delivery through pipe, a stop valve, a housing, an upper valve core, and a valve rod. The water delivery through pipe is connected to one of the ports of the two-way pump and is respectively connected to each side connecting pipe and the main connecting pipe. Stop valves are respectively installed between the water delivery through pipe and each side connecting pipe and the main connecting pipe. The stop valve includes a housing, an upper valve core, and a valve rod. The water delivery through pipe is fixedly and communicatively connected to the housing between it and each side connecting pipe and the main connecting pipe. The upper part of each housing penetrates, and a vertical upper valve core is respectively and sealingly rotatably connected. The upper valve core penetrates from the middle of the bottom end to the rear end. When the upper valve core rotates to a certain angle, the water delivery through pipe can be connected or disconnected from each side connecting pipe and the main connecting pipe. The top of the upper valve core is fixed with a valve rod coaxial with its rotation axis.

[0009] On the basis of the above technical solution, a upper gear ring is coaxially fixed to the valve rod. The front part of the top of the mounting seat is fixed with a horizontal guide seat. A horizontal sliding seat is slidably connected to the left and right of the guide seat, and a horizontal servo motor is fixed to the left end. The rotating shaft of the servo motor is coaxially fixed with a lead screw and is electrically connected to the controller. The storage battery is fixed to the top of the mounting seat, and the controller is fixed to the top of the storage battery. The lead screw is parallel to the sliding direction of the sliding seat and is threadedly connected to the sliding seat. A horizontal toothed plate is fixed to the left part of the rear end of the sliding seat. When the servo motor rotates forward and backward, the sliding seat can be driven to slide left and right along the guide seat through the lead screw. When the sliding seat slides left and right along the guide seat, the toothed plate can be alternately engaged with each upper gear ring.

[0010] On the basis of the above technical solution, an upper rack is installed on the right part of the sliding seat. Two horizontal optical rods are respectively fixed to the left and right parts of the front end of the upper rack, and a horizontal first screw rod is rotatably connected in the middle in the front-rear direction. The optical rods are slidably connected to the sliding seat in the front-rear direction, and the first screw rod is threadedly connected to the sliding seat. When the first screw rod rotates forward and backward, the upper rack can move forward and backward relative to the sliding seat. When the upper rack moves away from the guide seat by a certain distance, it can be horizontally corresponding to the toothed plate and engage with each upper gear ring together with the toothed plate.

[0011] On the basis of the above technical solution, the fastening mechanism includes a lower support seat made of non-metallic material. A horizontal lower support seat is fixed to the bottom end of the upper support seat. Two flexible braided belts are fixed to the left end of the lower support seat, and an annular electromagnet is fixed inside. The electromagnet is electrically connected to the controller. A stepped hole penetrates through the lower support seat up and down. The bottom of the stepped hole is threadedly connected with a removable cover. The upper part of the stepped hole is threadedly connected with a removable connecting pipe. The bottom of the connecting pipe protrudes from the lower support seat, and the upper part is hermetically inserted into the bottom of the diffusion channel in the up and down direction of the upper support seat. The top end of the connecting pipe can push up the lower valve core at the bottom of the diffusion channel in the up and down direction of the upper support seat, and a notch is radially penetrated through the top. A wire slot penetrates through the upper part of the lower support seat from left to right. The braided belt can be inserted into the wire slot. Winding mechanisms cooperating with the braided belt are installed on the front and rear parts of the lower support seat respectively.

[0012] On the basis of the above technical solution, the winding mechanism includes a first receiving groove, a guiding groove, a supporting block, a sliding block, a first ejector pin, an elastic pulling rope, a second screw rod, and a pushing plate. A first receiving groove is formed in the upper part of the lower support seat. The first receiving groove communicates with the upper part of the wire slot. Guide grooves are formed at both the front and rear ends of the inner wall of the first receiving groove. The left part of the guiding groove is horizontal, and the right part slopes upward to the right. A supporting block is inserted into the first receiving groove with a gap. Sliding blocks are fixed to both the front and rear ends of the supporting block. The sliding block is slidably connected to the left part of the guiding groove in the left and right directions, and is slidably connected to the right part of the guiding groove in the reciprocating direction from the lower left to the upper right. A plurality of vertical first ejector pins are fixed to the bottom end of the supporting block, and an elastic pulling rope is commonly fixed to the upper right part of the first receiving groove and the upper right part of the supporting block. The supporting block has a tendency to slide upward to the right along the guiding groove under the elastic pulling of the elastic pulling rope. When the sliding block is slidably connected to the left part of the guiding groove, the first ejector pin extends into the wire slot and can pierce into the braided belt in the wire slot, and when it slides to the rightmost part of the guiding groove, the first ejector pin disengages from the wire slot. A horizontal second screw rod is threadedly connected to the right part of the lower support seat in the left and right directions. A pushing plate is rotatably connected to the left part of the second screw rod. The pushing plate is slidably connected to the first receiving groove in the left and right directions, and the left end can be in contact with the right end of the supporting block.

[0013] Based on the above technical solution, the winding mechanism includes a second accommodation groove, a lower rack, a third screw rod, a handwheel, a support shaft, a support wheel, a lower gear ring, and a second thimble. A second accommodation groove is formed in the upper part of the lower support seat. The second accommodation groove is communicated with the upper part of the wire threading groove. A horizontal lower rack is slidably connected to the upper part of the second accommodation groove in the left-right direction. The lower rack is threadedly connected with a third screw rod in the left-right direction. The third screw rod is rotatably connected through the lower support seat. A handwheel is coaxially fixed to the left end of the third screw rod. A support shaft is fixed in the second accommodation groove in the front-back direction. The support shaft is coaxially rotatably connected with a support wheel. The middle part of the outer circumferential wall of the support wheel is recessed inward and coaxially fixed with a lower gear ring. A plurality of radial second thimbles are fixed to the outer circumferential wall of the support wheel at equal angles in the circumferential direction. There is always a second thimble inserted into the wire threading groove and capable of being inserted into the braided belt in the wire threading groove. When the third screw rod rotates forward and backward, the lower rack can slide left and right along the second accommodation groove. When the upper rack slides left and right, it can engage with and disengage from the upper part of the lower gear ring.

[0014] Compared with the prior art, the present invention has the following advantages: When the present invention is used, the liquid medium B is injected into the spherical cavity by using a syringe, and then the upper support seat is fastened to the mechanical equipment through the fastening mechanism. As the mechanical device vibrates, the upper support seat also vibrates accordingly. The liquid medium A and the liquid medium B start to reciprocate along the vibration direction. As the liquid medium B moves, it will gradually diffuse into the liquid medium A along the moving direction, so that an intuitive display can be carried out in the diffusion channel. By observing the diffusion state of the liquid medium B in each diffusion channel, the direction and degree of vibration can be known, and thus it can be judged whether it meets the requirements, realizing the simultaneous detection of vibrations in six directions of front, back, left, right, up, and down, and improving the detection efficiency.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] As Figures 1-8As shown in the figure, a mine mechanical vibration detection device includes an upper support seat 1 made of transparent material. The upper support seat 1 is penetrated by straight diffusion channels 2 in the front-back direction, left-right direction, and up-down direction, and a spherical cavity 3 is formed in the middle of it. At both ends of each diffusion channel 2 close to the outer wall of the upper support seat 1, parallel stepped light holes 4 are respectively opened. Direction control valves are respectively installed in each stepped light hole 4. Each diffusion channel 2 is connected through the spherical cavity 3 in the middle. A stepped screw hole 6 is opened in the upper right front part of the upper support seat 1. The bottom of the stepped screw hole 6 is connected to the spherical cavity 3. An internal hexagonal support cylinder 7 is coaxially and hermetically threadedly connected to the upper part of the stepped screw hole 6, and a syringe 8 is installed. A rubber plug 9 is hermetically fixed at the bottom of the internal hexagonal support cylinder 7. The syringe barrel of the syringe 8 is inserted into the upper part of the stepped screw hole 6, and the needle can penetrate through the rubber plug 9 and be inserted into the gap between the bottom of the stepped light hole 4 and the spherical cavity 3 and extend to the virtual center of the spherical cavity 3. A transparent, flowing, non-explosive and non-flammable liquid medium A is stored in the diffusion channels 2 and the spherical cavity 3 together. A colored, flowing, non-explosive and non-flammable liquid medium B is stored in the syringe 8. The liquid medium A and the liquid medium B have the same density and do not undergo biochemical reactions, are not flammable or explosive after mixing. The upper support seat 1 is equipped with a fastening mechanism.

[0026] During use, the liquid medium B is injected into the spherical cavity 3 by using the syringe 8, and then the upper support seat 1 is fastened to the mechanical equipment through the fastening mechanism. As the mechanical device vibrates, the upper support seat 1 also vibrates accordingly. The liquid medium A and the liquid medium B start to move back and forth along the vibration direction. As the liquid medium B moves, it will gradually diffuse into the liquid medium A along the moving direction, so that it can be visually displayed in the diffusion channels 2. By observing the diffusion state of the liquid medium B in each diffusion channel 2 (including the diffusion area and diffusion time), the direction and degree of vibration can be known, and thus it can be judged whether it meets the requirements, realizing the simultaneous detection of vibrations in six directions of front-back, left-right, up-down. The internal hexagonal support cylinder 7 and the rubber plug 9 can be replaced together, which is convenient for multiple uses.

[0027] Six groups of grating sensors are fixed in the upper support seat 1. Each group of grating sensors consists of a transmitter 12 and a receiver 13. The two penetrated ends of each diffusion channel 2 respectively correspond to a group of grating sensors. The transmitter 12 and the receiver 13 in the grating sensors are arranged oppositely on the radial two sides with respect to the diffusion channel 2. Each group of grating sensors is commonly electrically connected to a controller 14. The controller 14 is electrically connected to a storage battery 15, a display screen 16, and a control button 17.

[0028] Furthermore, when the liquid medium B does not fully diffuse in the diffusion channel 2, the receiver 13 of the grating sensor corresponding to the diffusion channel 2 can normally receive the light beam emitted by the transmitter 12. When the liquid medium B fully diffuses in the diffusion channel 2, the receiver 13 of the grating sensor corresponding to the diffusion channel 2 cannot receive the light beam emitted by the transmitter 12. By determining the duration of the corresponding grating sensor from being able to receive the light beam to not being able to receive the light beam through the controller 14 and displaying it on the display screen 16, the diffusion state of the liquid medium B in each diffusion channel 2 can be indirectly known, and then the direction and degree of vibration can be known, saving the trouble of visually observing each diffusion channel 2 one by one.

[0029] The control valve is a one-way valve. The one-way valve includes a lower valve core 19, a valve hole 20 and a compression spring 21. The lower valve core 19 is slidably connected in parallel with the stepped light hole 4, and a compression spring 21 is fixedly arranged at the end of the lower valve core 19 far from the outer wall of the upper support seat 1 and the stepped surface of the stepped light hole 4 close to the spherical cavity 3. A valve hole 20 penetrates through the outer wall of the lower valve core 19 along the sliding direction, and has a tendency to slide along the stepped light hole 4 away from the spherical cavity 3 under the elastic repulsive force of the compression spring 21. The valve hole 20 can be hermetically blocked by the stepped surface of the stepped light hole 4 close to the outer wall of the upper support seat 1 under the elastic repulsive force of the compression spring 21.

[0030] Furthermore, after the detection is completed, by manually pressing any one-way valve in the direction of the spherical cavity 3, the stepped surface of the stepped light hole 4 can be made to release the blockage of the valve hole 20, so that the diffusion channel 2 where the one-way valve is located is connected to the outside. Then, by making the diffusion channel 2 face downwards, the mixture of the liquid medium A and the liquid medium B can be discharged under the action of gravity, and at the same time, it is convenient to pour in a cleaning agent to clean the diffusion channel 2 and the spherical cavity 3, thus facilitating the next use.

[0031] The upper support base 1 is also equipped with a detachable cleaning mechanism. The cleaning mechanism includes a mounting base 23, side connecting pipes 24, a main connecting pipe 25, a docking cylinder 26, a screw cylinder 27, a thimble 271, and a two-way pump 28. Four vertical side connecting pipes 24 and one vertical main connecting pipe 25 are fixed to the bottom end of the mounting base 23. Horizontally-mounted docking cylinders 26 are respectively and fixedly communicated with the bottom parts of the side connecting pipes 24. Each of the docking cylinders 26 is docked with the diffusion channels 2 in the front-back direction and left-right direction of the upper support base 1. Each of the docking cylinders 26 is coaxially and hermetically thread-connected with a screw cylinder 27. The end of each screw cylinder 27 far from the upper support base 1 is closed, and the end close to the upper support base 1 penetrates. The middle part of each screw cylinder 27 penetrates in the radial direction and is communicated with the main connecting pipe 25, and can be hermetically inserted into the penetration part of the diffusion channel 2. The screw cylinder 27 can push the lower valve core 19 so that the screw cylinder 27 is communicated with the spherical cavity 3 through the valve hole 20. The main connecting pipe 25 is vertically docked with the upper part of the diffusion channel 2 in the up-down direction of the upper support base 1, and a vertically-penetrating thimble 271 is fixed to the inner wall of the bottom end. The thimble 271 can push down the one-way valve in the diffusion channel 2 docked with the main connecting pipe 25. The mounting base 23 is equipped with a two-way pump 28. The two-way pump 28 is electrically connected to the controller 14, and one of its ports is simultaneously communicated with each auxiliary connecting pipe 48 and the main connecting pipe 25.

[0032] During use, the diffusion channels 2 and the spherical cavity 3 are cleaned by the cleaning mechanism to improve the cleaning efficiency. Specifically, by manually rotating the screw cylinder 27, it is controlled whether the screw cylinder 27 is inserted into the diffusion channel 2, and further whether to push the corresponding lower valve core 19 to make the screw cylinder 27 communicate with the spherical cavity 3. In the case of communication, manually push the lower valve core 19 at the bottom of the upper support base 1, and then the two-way pump 28 sucks the external cleaning liquid into the spherical cavity 3 and the diffusion channels 2, and finally discharges from the bottom of the diffusion channel 2 in the up-down direction of the upper support base 1, thus achieving the flushing effect, which is more convenient and efficient compared with manual flushing.

[0033] The cleaning mechanism also includes a water delivery pipe 29, a stop valve, a shell 31, an upper valve core 32, and a valve stem 33. The water delivery pipe 29 is connected to one of the ports of the two-way pump 28, and is respectively connected to each side connecting pipe 24 and the main connecting pipe 25. Stop valves are respectively installed between the water delivery pipe 29 and each side connecting pipe 24 and the main connecting pipe 25. The stop valve includes a shell 31, an upper valve core 32 and a valve stem 33. The water delivery pipe 29 is respectively fixedly connected to each side connecting pipe 24 and the main connecting pipe 25 with a shell 31. The upper part of each shell 31 passes through and is respectively sealed and rotatably connected with a vertical upper valve core 32. The upper valve core 32 passes through from the middle of the bottom end to the rear end. When the upper valve core 32 is rotated to a certain angle, the water delivery pipe 29 can be connected and disconnected with each side connecting pipe 24 and the main connecting pipe 25. The top of the upper valve core 32 is fixed with a valve stem 33 coaxial with its rotation axis.

[0034] Furthermore, in the process of manually pushing the lower valve core 19 at the bottom of the upper support seat 1 and using the two-way pump 28 for flushing, by rotating the corresponding valve stem 33, it is possible to control whether the corresponding side connecting pipe 24 and the main connecting pipe 25 are connected, thereby controlling whether the corresponding diffusion channel 2 is connected, so as to control the flow direction of the cleaning agent, thereby achieving different flushing effects.

[0035] The valve stem 33 is coaxially fixed with an upper gear ring 34, a horizontal guide seat 35 is fixed to the front of the top of the mounting seat 23, the guide seat 35 is slidably connected to a horizontal sliding seat 36, and a horizontal servo motor 37 is fixed to the left end, a screw rod 38 is coaxially fixed to the rotating shaft of the servo motor 37, and is electrically connected to the controller 14, the battery 15 is fixed to the top of the mounting seat 23, the controller 14 is fixed to the top of the battery 15, the screw rod 38 is parallel to the sliding direction of the sliding seat 36, and is threadedly connected to the sliding seat 36, a horizontal tooth plate 39 is fixed to the left part of the rear end of the sliding seat 36, when the servo motor 37 rotates forwards and reversely, the screw rod 38 can drive the sliding seat 36 to slide left and right along the guide seat 35, and when the sliding seat 36 slides left and right along the guide seat 35, the tooth plate 39 can alternately mesh with each upper gear ring 34.

[0036] Further, during the process of flushing by using the two-way pump 28 while manually pushing the lower valve core 19 at the bottom of the upper support seat 1, by controlling the forward and reverse rotation of the servo motor 37, the cooperation between the lead screw 38 and the sliding seat 36 can be utilized to make the sliding seat 36 and the toothed plate 39 reciprocate left and right relative to the guide seat 35. As a result, the toothed plate 39 can be alternately engaged with each upper toothed ring 34, causing the corresponding valve stem 33 and the upper valve core 32 to rotate. Subsequently, each side connecting pipe 24 and the main connecting pipe 25 are successively conducted through the spherical cavity 3 to the diffusion channel 2 at the bottom of the upper support seat 1. Compared with the situation where each side connecting pipe 24 and the main connecting pipe 25 are simultaneously conducted to the diffusion channel 2 at the bottom of the upper support seat 1, the pressure of the two-way pump 28 for flushing a single diffusion channel 2 is greater, and its flushing effect is better. Thus, the residue of the colored liquid medium B is reduced, and the influence on the next detection is lowered.

[0037] A upper rack 40 is installed on the right part of the sliding seat 36. On the left and right parts at the front end of the upper rack 40, a horizontal optical rod 41 is fixed respectively, and a horizontal first screw rod 42 is rotatably connected in the front-back direction in the middle. The optical rod 41 is slidably connected with the sliding seat 36 in the front-back direction, the first screw rod 42 is threadedly connected with the sliding seat 36. When the first screw rod 42 rotates forward and backward, the upper rack 40 can move back and forth relative to the sliding seat 36. When the upper rack 40 is at a certain distance away from the guide seat 35, it can be horizontally corresponding to the toothed plate 39 and engage with each upper toothed ring 34 together with the toothed plate 39.

[0038] Further, by manually rotating the first screw rod 42 forward and backward, the upper rack 40 can move back and forth to be horizontally corresponding to the toothed plate 39 or not. When they are corresponding, it can engage with each upper toothed ring 34 together with the toothed plate 39. At this time, if the sliding seat 36 reciprocates left and right under the drive of the lead screw 38, the valve stems 33 and the upper valve cores 32 can be rotated simultaneously, so as to control whether each side connecting pipe 24 and the main connecting pipe 25 are simultaneously conducted to the diffusion channel 2 at the bottom of the upper support seat 1, that is, the switching between two modes is realized, namely, the single rotation of the valve stems 33 and the upper valve cores 32, or the simultaneous rotation of the valve stems 33 and the upper valve cores 32, so as to achieve different cleaning effects.

[0039] The fastening mechanism includes a lower support base 43 made of non-metallic material. A horizontal lower support base 43 is fixed to the bottom end of the upper support base 1. Two flexible braided belts 44 are fixed to the left end of the lower support base 43, and an annular electromagnet 45 is fixed inside. The electromagnet 45 is electrically connected to the controller 14. A stepped hole 46 runs through the lower support base 43 vertically. A removable cover 47 is threadedly connected to the bottom of the stepped hole 46. A removable connecting pipe 48 is threadedly connected to the upper part of the stepped hole 46. The bottom of the connecting pipe 48 protrudes from the lower support base 43, and the upper part is hermetically inserted into the bottom of the diffusion channel 2 in the vertical direction of the upper support base 1. The top end of the connecting pipe 48 can push up the lower valve core 19 at the bottom of the diffusion channel 2 in the vertical direction of the upper support base 1, and there is a notch radially penetrating through the top. A wire slot 49 runs through the upper part of the lower support base 43 horizontally. The braided belt 44 can be inserted into the wire slot 49. Twisting mechanisms cooperating with the braided belt 44 are installed on the front and rear parts of the lower support base 43 respectively.

[0040] Further, during detection, the connecting pipe 48 is removed and the cover 47 is installed. The braided belt 44 is used to tie around the corresponding device or mechanism, and the braided belt 44 is passed through the wire slot 49 from right to left. Then, the braided belt 44 is tightened by using the twisting mechanism, so that the lower support base 43 is tightly attached to the device or mechanism to be detected, realizing the synchronous vibration of the lower support base 43 and the upper support base 1 with the device or mechanism to be detected, and then realizing the detection function. During this period, the electromagnet 45 can also be used to magnetically adsorb the device or mechanism made of magnetically adsorbable material to improve the fastening effect and the accuracy of detection. During cleaning, the cover 47 is removed and the connecting pipe 48 is reinstalled. The reciprocating flushing can be realized by changing the two-way pump 28.

[0041] The winding mechanism includes a first receiving groove 51, a guiding groove 52, a supporting block 53, a sliding block 54, a first ejector pin 55, an elastic cord 56, a second screw rod 57, and a pushing plate 58. A first receiving groove 51 is formed in the upper part of the lower supporting seat 43. The first receiving groove 51 communicates with the upper part of the wire threading groove 49. At the front and rear ends of the inner wall of the first receiving groove 51, a guiding groove 52 is formed respectively. The left part of the guiding groove 52 is horizontal, and the right part slopes upward to the right. A supporting block 53 is inserted into the first receiving groove 51 with a clearance. At the front and rear ends of the supporting block 53, a sliding block 54 is fixed respectively. The sliding block 54 is slidably connected to the left part of the guiding groove 52 in the left-right direction and is slidably connected to the right part of the guiding groove 52 in the reciprocating direction from the lower left to the upper right. At the bottom end of the supporting block 53, a plurality of vertical first ejector pins 55 are fixed, and at the upper right part of the supporting block 53 and the upper right part of the first receiving groove 51, an elastic cord 56 is fixed together. Under the elastic pulling force of the elastic cord 56, the supporting block 53 has a tendency to slide upward to the right along the guiding groove 52. When the sliding block 54 is slidably connected to the left part of the guiding groove 52, the first ejector pin 55 extends into the wire threading groove 49 and can pierce into the braided belt 44 in the wire threading groove 49. When it slides to the rightmost part of the guiding groove 52, the first ejector pin 55 disengages from the wire threading groove 49. On the right part of the lower supporting seat 43, a horizontal second screw rod 57 is threadedly connected in the left-right direction. On the left part of the second screw rod 57, a pushing plate 58 is rotatably connected. The pushing plate 58 is slidably connected to the first receiving groove 51 in the left-right direction, and the left end of the pushing plate 58 can be in contact with the right end of the supporting block 53.

[0042] Further, as a solution for the first winding mechanism, before passing the braided belt 44 through the wire threading groove 49, manually rotate the second screw rod 57 forward to move the pushing plate 58 to the rightmost side of the first receiving groove 51. At this time, under the action of the elastic cord 56, the supporting block 53 is at the rightmost part of the first receiving groove 51, and the first ejector pin 55 disengages from the wire threading groove 49. Then insert the braided belt 44 into the wire threading groove 49 and gradually tighten it to the left. Subsequently, manually rotate the second screw rod 57 in the reverse direction to use the pushing plate 58 to push the supporting block 53 to move to the left, so that the first ejector pin 55 descends and pierces into the braided belt 44 to drag it to move to the left, thereby achieving the tightening effect and making the lower supporting seat 43 fit tightly with the device or mechanism to be detected. When it is necessary to release, just rotate the second screw rod 57 forward, and under the action of the elastic cord 56, the supporting block 53 can be reset, and the first ejector pin 55 can be disengaged from the braided belt 44. At this time, the braided belt 44 can be withdrawn from the wire threading groove 49.

[0043] The winding mechanism includes a second receiving groove 59, a lower rack 60, a third screw 61, a handwheel 62, a support shaft 63, a support wheel 64, a lower gear ring 65, and a second thimble 66. A second receiving groove 59 is formed in the upper part of the lower support base 43. The second receiving groove 59 communicates with the upper part of the wire threading groove 49. A horizontal lower rack 60 is slidably connected to the upper part of the second receiving groove 59 in the left-right direction. The lower rack 60 is threadedly connected with a third screw 61 in the left-right direction. The third screw 61 is rotatably connected through the lower support base 43. A handwheel 62 is coaxially fixed to the left end of the third screw 61. A support shaft 63 is fixed in the second receiving groove 59 in the front-back direction. The support shaft 63 is coaxially rotatably connected with a support wheel 64. The middle part of the outer circumferential wall of the support wheel 64 is recessed inward and coaxially fixed with a lower gear ring 65. A plurality of radial second thimbles 66 are fixed to the outer circumferential wall of the support wheel 64 at equal angular intervals in the circumferential direction. There is always a second thimble 66 inserted into the wire threading groove 49 and capable of being inserted into the braided belt 44 in the wire threading groove 49. When the third screw 61 rotates forward and backward, the lower rack 60 can slide left and right along the second receiving groove 59. When the upper rack 40 slides left and right, it can engage with and disengage from the upper part of the lower gear ring 65.

[0044] Further, as a second solution for the winding mechanism, before passing the braided belt 44 through the wire threading groove 49, manually rotate the third screw 61 forward to move the lower rack 60 to the leftmost part of the second receiving groove 59. At this time, the lower rack 60 disengages from the lower gear ring 65. Then insert the braided belt 44 into the wire threading groove 49. At this time, the braided belt 44 is pierced by the second thimble 66 and pushes the second thimble 66 to move leftward, and causes the support wheel 64 to rotate clockwise (in the front view angle), gradually tightening. Subsequently, rotate the third screw 61 in the reverse direction, and the lower rack 60 can move rightward along the second receiving groove 59 and gradually engage with the lower gear ring 65, so that the support wheel 64 rotates clockwise (in the front view angle). Then use the second thimble 66 to drag the braided belt 44 to move leftward, thereby achieving the tightening effect and making the lower support base 43 fit tightly with the device or mechanism to be detected. When it is necessary to release, just rotate the third screw 61 forward to move the lower rack 60 to the leftmost part of the second receiving groove 59. At this time, the lower rack 60 disengages from the lower gear ring 65, and at this time, the braided belt 44 can be withdrawn from the wire threading groove 49.
