15 two sides match, and are equipped with second limit hole 21 corresponding with the first limit hole 15 on the surface of side plate 23.
When the bindiny mechanism 8 works, in the case where coil 82 is not powered on, limited post 81 is acted on due to the elastic force of spring 84
And stretch out, to pass through the first limit hole 15 and the second limit hole 21, column 1 and girder 2 are fixed；It is powered in coil 82
In the case where, magnetic field is generated since coil 82 is powered, generates suction to magnetic limited post 81 after magnetizable metal block 83, from
And limited post 81 is retracted, the binding force between column 1 and girder 2 is released, so that can produce displacement between girder 2 and column 1.
The inside of the column 1 is additionally provided with the elevating mechanism of vertical direction running, and the elevating mechanism and bindiny mechanism 8 are solid
It connects, since girder 2 and bindiny mechanism 8 are affixed, therefore can finally adjust girder 2 by elevating mechanism in the height of vertical direction.
As shown in figure 5, the elevating mechanism includes gear 11, motor 14 and chain 12, wherein
The motor 14 is mounted on the interior bottom of part of the column 1 equipped with the first limit hole 15, and the motor 14 passes through spiral shell
Bar is horizontally fixed in column 1.
The gear 11 is two, is separately mounted to the inner top on the output shaft of motor 14 with column 1, is mounted on column
11 center of gear of 1 inner top is connected with bearing, and Bearing inner is connected with connecting rod, which passes through bolt and column 1
Inner top connection.
The chain 12 is circular path, and is matched with two gears 11, realizes the transmission of 11 power of gear；The shell
There are two the vertical fixation holes 87 of body 85, and in the chain 12 of the circular path, 12 activity of chain positioned at side passes through one
Fixation hole, the chain 12 positioned at the other side are threaded through in another fixation hole by the fixation of fixture 13.
As shown in fig. 6, the fixture 13 includes mutually matched first fixture block 131 and the second fixture block 132, first folder
131 surface of block is equipped with several grooves, and 132 surface of the second fixture block is equipped with several protrusions corresponding with groove, described convex
The rolling ring risen across chain 12 is matched with groove, and first fixture block 131 and 132 bottom of the second fixture block are equipped with and the shell
The limit convex shoulder 133 that body 85 matches.
As shown in fig. 7, the bottom of bindiny mechanism 8 is located at the limit of fixture 13 when bindiny mechanism 8 is threaded through on chain 12
On convex shoulder 133, since bindiny mechanism 8 and girder 2 are affixed, therefore make can not between bindiny mechanism 8 and fixture 13 for the quality of girder 2
Relative motion is generated, can stablize and fixture 13 is followed to move up and down.
As shown in figure 8, being mounted on the schematic diagram inside column 1 for elevating mechanism and bindiny mechanism 8, work in elevating mechanism
Before, it first powers for the coil 82 in bindiny mechanism 8, retracts limited post 81, release the binding force between column 1 and girder 2, after
The rotation of motor 14 of elevating mechanism drives two gears 11 accordingly to rotate, and rotates chain 12 along circular path, to drive chain
Fixture 13 on item 12 generates upper and lower displacement, which is transferred to girder 2 by bindiny mechanism 8, to realize girder 2 along column 1
It moves up and down, when girder 2 is adjusted to suitable height, motor 14 stops operating, at this point, disconnecting the coil 82 in mechanism 8
Power supply, stretch out limited post 81 under the elastic force effect of spring 84, and column 1 and girder 2 is fixed, complete 2 height of girder
Adjusting.
In the structure design of column 1, shift length caused by fixture 13 when being turned around according to the rotation of motor 14, to determine
The spacing of first limit hole 15 on 1 surface of column in the vertical direction, therefore when girder 2 needs to be adjusted to specified altitude assignment, pass through
Adjusting can be completed in the circle number that control motor 14 rotates.
As shown in figure 9, the inside of the girder 2 is equipped with horizontal mobile mechanism 10, the part of the horizontal mobile mechanism 10
It extends to 2 outside of girder and is connected with bridge piece 9, the loading beam 3 is fixedly mounted on the bridge piece 9.
The horizontal mobile mechanism 10 includes motor 14, external screw thread axis 101 and the nut 102, wherein the motor 14
It is mounted on the side in girder 2, the motor 14 is to be horizontally mounted and with 2 inner wall of girder there is evacuation horizontal mobile mechanism 10 to transport
Dynamic gap, motor 14 are fixed by bolt holder with girder 2；The output shaft of the external screw thread axis 101 and motor 14 is logical
Shaft coupling connection is crossed, is made rotating motion by the output shaft driving of motor 14, the length of the external screw thread axis 101 is less than girder 2
Length, and be connected in outer thread spindle 101 far from one end of motor 14 and reinforce the fixed bearing block 103 of external screw thread axis 101；It is described
Nut 102 is set in 101 surface of external screw thread axis, and realizes horizontal motion when outer thread spindle 101 makes rotating motion.
It is easily understood that nut 102 is equipped with position-limit mechanism, which follows outer spiral shell for limiting nut 102
Line axis 101 rotates.For example, the cunning that the position-limit mechanism can be the groove being arranged on nut 102 and be arranged on girder 2
The limit to nut 102 is realized in block, groove and sliding block mutual cooperation；Sliding block and setting on nut 102 are either set
The limit to nut 102 is realized in groove on girder 2, groove and sliding block mutual cooperation.
Two groups of horizontal mobile mechanisms 10, two motors in two groups of horizontal mobile mechanisms 10 are equipped with inside every girder 2
14 be the inside for being oppositely arranged on girder 2, and two external screw thread axis 101 are to be arranged in parallel, so that nut 102 is mutual in moving process
It does not interfere.During adjusting 10 position of horizontal mobile mechanism, the rotation of motor can be directly controlled by physical switch, thus
Realize that position is adjusted, and artificially control prevents the nut 102 in two groups of horizontal mobile mechanisms 10 from colliding.Further, may be used
Infrared ambulator is installed in the side of nut 102, prevents nut 102 from colliding in moving process.
As shown in Figure 10, the nut 102 includes the threaded ferrule 1021 for being set in 101 surface of external screw thread axis, the spiral shell
It invaginates at the top of line lasso 1021, and is nested with newel 1022 in invagination region, the newel 1022 is close to threaded ferrule
1021 one end is connected with spring 84, and the other end of the newel 1022 extends to outside girder 2, and connects in extension

Hole, the top of the girder 2 are equipped with the second groove of evacuation 1022 motion path of newel, and the second groove is set in the present embodiment
There are 2, every corresponds to the nut 102 for placing a horizontal mobile mechanism 10, and the width of second groove is 60mm.
As shown in figure 11, the bridge piece 9 includes in four overlap holes for wearing and being fixed on the plate 1023 respectively
Bearing bar 91, bearing bar 91 is the structure with certain tensile strength, and bearing bar 91 is carried out by taking screw rod as an example in the present embodiment
Assembling, the bearing bar 91 extend towards the direction far from the plate 1023, and the length for extending to bearing bar 91 is greater than girder 2
The height of itself, and bearing plate 92 is installed in the bottom of bearing bar 91, the loading beam 3 is fixed on the bearing plate 92, is
Reinforce the bearing capacity of bearing plate 92, bearing plate 92 preferably uses metal material, and bearing plate 92 omits at a distance from 2 bottom of girder
Greater than the height of loading beam 3, and the rear and front end of loading beam 3 is respectively mounted on the horizontal mobile mechanism 10 on the girder 2 of front and back two
In, the shift action of the horizontal mobile mechanism 10 on same root loading beam 3 is consistent.
Horizontal mobile mechanism 10 at work, motor 14 rotation drive external screw thread axis 101 generate rotation, nut 102 not with
It is rotated with external screw thread axis 101, to generate the displacement of horizontal direction under the guiding of screw thread, loading beam 3 is driven to realize level side
