Description
Technical field
The present invention relates to a kind of clamp of sensor, especially relate to a kind of lattice-shaped vibration of elevator test clamp of sensor.
Background technology
At present, most inclined-planes elevator adopts aluminium manufacture, and inoperative to magnetive attraction, surface is again lattice structure, causes in the time it being carried out to vibration characteristics test, and sensor cannot be installed fixing.Or the structure of sectional fixture is too complicated, mount and dismount consuming time longer, even need to be in the time of installation and removal, elevator is out of service, in the time that elevator is detected, efficiency is not high.
Summary of the invention
The object of the present invention is to provide a kind of lattice-shaped vibration of elevator test clamp of sensor, can quickly and accurately the sensor with magnetic force be fixed on the inoperative aluminum elevator of magnetic force surface, thereby it is quick and convenient to realize whole test process, testing efficiency is improved significantly.
The technical solution adopted in the present invention is:
Comprise base plate, turning handle, handle fixed block, U-shaped handle bracket, drive block and slide block; Turning handle straight-bar is inserted through after handle fixed block, fix with nut from turning handle below, turning handle and handle fixed block form revolute pair, and U-shaped handle bracket is fixed on base plate, handle fixed block is contained in U-shaped handle bracket, and handle fixed block and handle bracket form revolute pair; The base plate side opening that is positioned at U-shaped handle bracket one side is jagged, upper end of slide block face has two projections, all there is gib block slide block two sides, the gib block of slide block two sides inserts in two gathering sills of base plate one side breach, one end of drive block is embedded between two projections of upper end of slide block face and forms revolute pair, the straight-bar of turning handle and the other end of drive block through handle fixed block are threaded, and have respectively interlock screw die at slider bottom with respect to base plate one side of slide block; Being positioned on the base plate of U-shaped handle bracket opposite side is installation of sensors region.
The useful effect that the present invention has is:
The vibration of elevator test clamp of sensor that the present invention adopts, has easy to operate, feature efficiently.By rotation turning handle, can realize sensor fast and elevator is fixed, to install and ensure to complete in 5 seconds, dismounting ensures to complete in 3 seconds, can not need to stop elevator and move and just can complete test process, has greatly improved the efficiency of vibration of elevator characteristic test.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, the present invention includes base plate 1, turning handle 3, handle fixed block 4, U-shaped handle bracket 5, drive block 9 and slide block 10; Turning handle 3 straight-bars are inserted through after handle fixed block 4, fix with nut from turning handle 3 belows, ensure that turning handle 3 does not almost have relative displacement (being less than 1 millimeter) on the interior above-below direction of handle fixed block 4, turning handle 3 forms revolute pair with handle fixed block 4, the bottom of U-shaped handle bracket 5 is fixed on base plate 1 with two support clamp nuts 7, handle fixed block 4 is contained in U-shaped handle bracket 5, be connected with right pin 6 with left pin 2, handle fixed block 4 forms revolute pair with handle bracket 5; Base plate 1 side opening that is positioned at U-shaped handle bracket 5 one sides is jagged, there are two projections slide block 10 upper surfaces, all there is gib block slide block 10 two sides, the gib block of slide block 10 two sides inserts in two gathering sills of base plate 1 one side breach, one end of drive block 9 is embedded between two projections of slide block 10 upper surfaces and forms revolute pair with slide block fastening bolt 8 and slide block clamp nut 11, is threaded with the other end of drive block 9 through the straight-bar of the turning handle 3 of handle fixed block 4; Being positioned on the base plate 1 of U-shaped handle bracket 5 opposite sides is installation of sensors region 12.
Base plate 1 material is 45# steel, and oxide treatments has been carried out on surface, is convenient to the fixing of magnetic sensor, can prevent that again surface from corrosion occurring.
Turning handle 3 one end are handle portion, can facilitate manual rotation; The other end is screw rod, can move to the left or to the right with respect to base plate 1 by rotarily driving slide block 10.
The two sides that handle fixed block 4 is adjacent with U-shaped handle bracket 5 does not contact, but middle connects by pin, can ensure that both only relatively rotate.
The two sides that drive block 9 is adjacent with slide block 10 does not contact, but middle connects by fastening bolt, can ensure that both only relatively rotate.
Base plate 1 right side, by driving gathering sill in centre, has the effect of guide rail, and guarantee slide block 10 two sides gib blocks are done left and right relative motion in gathering sill.
Interlock screw die 13 has two of left and right, and left side a slice is fixed on below base plate left side, and base plate keeps static relatively; A slice and the slide block on the right can be integral structure, follow the relative base plate of slide block and do left or right motion, thereby by interlock elevator surface grid 14, fixture is fixed on elevator surface.In addition, little 3 millimeter of width of the Thickness Ratio elevator surface groove 15 of interlock screw die 13, little 5 millimeter of depth ratio elevator surface groove, can ensure that interlock screw die 13 puts into elevator surface groove smoothly, can ensure again fast and 14 interlocks of elevator surface grid.Annular knurl processing has been done on occlusal splint 13 surfaces, can strengthen and elevator surface grid 14 between friction force, make interlock better effects if.
Principle of work of the present invention is as follows:
In the time of work, by rotation turning handle 3, band movable slider 10 moves to the left or to the right, thereby adjusts the spacing of the interlock screw die 13 of the clamp base left and right sides, and interlock screw die 13 is embedded in elevator surface groove 15.Develop behind elevator surface guarantee base plate bottom surface, continue rotation turning handle 3, just can reach the fixing object of fixture and elevator by interlock screw die 13 and the interlock of elevator surface grid 14, and can ensure 12 bottom surfaces, fixture upper sensor installation region and the surperficial keeping parallelism of elevator.In placing, there is the sensor of magnet on installation of sensors region 12, the vibration characteristics that just can start to test elevator.After having tested, rotate in the opposite direction turning handle 3, just can fast fixture be separated with elevator.
Above-mentioned embodiment is used for the present invention that explains, instead of limits the invention, and in the protection domain of spirit of the present invention and claim, any amendment and change that the present invention is made, all fall into protection scope of the present invention.
