Detailed description of the invention
For being more fully understood that the present invention, the invention will be further described below in conjunction with the accompanying drawings, but embodiments of the present invention are not limited to this.
Embodiment 1:
As shown in figures 1 to 6, a kind of self adaptation angle adjusting mechanism for jacking apparatus, including upper plate 1, lower shoe 6, it is provided with between described upper plate 1 and lower shoe 6 and intersects and first connecting rod group 8 that length is equal and second connecting rod group 2.
First connecting rod group 8 in the outer part and second connecting rod group in the inner part 2 are rotationally connected with upper plate 1 and lower shoe 6 respectively by four bearing blocks 7.
Two connecting rods of first connecting rod group 8 with corresponding outside two bearing blocks 7 be connected, two connecting rods of second connecting rod group 2 with corresponding inside two bearing blocks 7 be connected.
Two connecting rod tops of first connecting rod group 8 are respectively perpendicular with middle part and are welded with parallel two piece gag lever post.The guide rail 4 of the annular of fluting in the middle of having two between top gag lever post 5 and lower limit bar 9.Guide rail 4 be arranged in parallel with two connecting rods of first connecting rod group 8.
Two connecting rods of second connecting rod group 2 are each passed through the fluting of guide rail 4, and two guide rails 4 are respectively equipped with spring 3 in the space of the annular of fluting；One end of spring 3 is fixed on top gag lever post 5, and the other end is flexibly connected with the connecting rod of second connecting rod group 2；When inverse (suitable) hour hands of the connecting rod of first connecting rod group 8 rotate, two connecting rods of second connecting rod group 2 move in the fluting of guide rail 4, and banking motion compresses (release) spring 3 while rotating.
Two gag lever posts are for limiting the rotation of 2 two connecting rods of second connecting rod group, and wherein lower limit bar 9 is used for limiting original state (0 °), and top gag lever post 5 is used for limiting end-state (80 °)；
As shown in Figure 1 and Figure 2, during original state, upper plate 1 is 0 ° with the angle of horizontal plane, and second connecting rod group 2 is tangent with lower limit bar 9, and the spring 3 in guide rail 4 is in long status, does not stresses.
When two connecting rods of second connecting rod group 2 rotate counterclockwise, second connecting rod group 2 and the angle α of horizontal plane1Being gradually increased, the spring 3 in guide rail 4 is gradually compressed, and starts elasticity of saving potential energy, and its suffered pressure direction is vertical with second connecting rod group 2.
Simultaneously as the rotation of second connecting rod group 2 drives first connecting rod group 8 also to rotate counterclockwise, first connecting rod group 8 and the angle α of horizontal plane2It is gradually reduced.Now, upper plate 1 starts to turn forward due to the drive of connection rod set, and upper plate 1 is gradually increased with the angle theta of horizontal plane.
The length of four connecting rods is the shortest, and adaptive mechanism whole height can be made the lowest, is conducive to stable and saves material, but when upper plate 1 is in maximum rollover states (as shown in Figure 5 and Figure 6), upper plate 1 must not extrude lower shoe 6.
As shown in Figure 3 and Figure 4, upper plate 1 and angle theta=45 ° of horizontal plane.As shown in Figure 5 and Figure 6, during end-state, upper plate 1 is 80 ° with the angle theta of horizontal plane, and the spring 3 in guide rail 4 is compressed to the shortest, and the elastic potential energy saved is maximum.
It is Recovery Process that the angle theta of upper plate 1 and horizontal plane is returned to 0 ° by 80 °, and Recovery Process is the inverse process of said process.Ignore the height of four bearing blocks 7, between each major parameter variable, have a relationship below:
α1=α0+dα1 (1)
α2=α0+dα2 (2)
Wherein, α1And α2It is respectively the angle of second connecting rod group 2 and first connecting rod group 8 and horizontal plane；α0Initial angle for second connecting rod group 2 and first connecting rod group 8 with horizontal plane；dα1With d α2The angle that respectively second connecting rod group 2 and first connecting rod group 8 are turned over, l is the length of connecting rod, and d is the distance between Left hand bearing block and right-hand axis bearing, and θ is the angle of upper plate 1 and horizontal plane.
The angle d α that angle (flip angle) θ of upper plate 1 and horizontal plane is turned over about second connecting rod group 21Functional image as shown in Figure 7.By in image it can be seen that θ Yu d α1The most linear, during original state, d α1=0, θ=0；As d α1When=27.1 °, θ=45 °；During end-state, d α1=53.4 °, θ=80 °.It is consistent with practical situation.The movement locus of the simplified model of switching mechanism and about 1 two end points of upper plate is as shown in Figure 8.
When specifically applying, the lower shoe 6 of the present embodiment mechanism is fixed on the ground, then is arranged on upper plate 1 being bolted bottom hydraulic jacking device.When the effect being subject to by jacking load, having a horizontal forward thrust and anticlockwise moment of flexure to upper plate 1, second connecting rod group 2 rotates counterclockwise, and drives upper plate 1 to overturn forward, and its motor process is as previously described.
It is arranged on upper plate 1 owing to the base plate of hydraulic jacking device is bolted, so when upper plate 1 is due to the effect changed by jacking load angle, when automatically turning forward, hydraulic jacking device will be driven to turn forward.When hydraulic jacking device bearing load reduces, horizontal thrust and moment of flexure suffered by upper plate 1 reduce the most accordingly, now saved elastic potential energy due to spring 3 by compression, can produce restoring force promotes second connecting rod group 2 opposite direction to rotate clockwise, driving upper plate 1 to turn over, its motor process is Recovery Process.
It is arranged on upper plate 1 owing to the base plate of hydraulic jacking device is bolted, so when upper plate 1 is turned over, the axis of hydraulic jacking device will be driven to adjust (reply) the most afterwards.
In conjunction with foregoing motor process, owing to this mechanism can automatically reply, can realize hydraulic jacking device bearing load by the motion of this angle adjusting mechanism the most consistent with its axis, the excursion of angle is 0-80 °, as shown in Figure 7.When jacking load change is bigger, jacking apparatus can be taken advantage of a situation regulation automatically, remain that carrying direction is consistent with its axis, avoid and make due to the change of load angle hydraulic lifting parts be damaged deformation, and the pressure energy of liquid can also be better profited from, keep stable jacking power output, improve ultimate bearing capacity, reached to bear the purpose of tilting load.
Embodiment 2:
As it is shown in figure 9, the present embodiment is basically identical with the technical scheme that embodiment 1 is used, differs only in lower shoe 6 bottom surface and be provided with the pad 10 of quality of rubber materials.When mechanism adapts to the change of incline angle of load degree, for preventing upper plate 1 run-off the straight change from causing the weight of jacking that transverse shifting can occur, increase a pad 10, can be different according to the stress of lower shoe 6 different parts, rubber can occur uneven gauge to change, the upper plate contacting jacking weight will not be changed in run-off the straight, thus ensured that weight will not occur transverse shifting, it is possible to stablize jacking.
Self adaptation angle adjusting mechanism provided by the utility model is applicable not only in hydraulic jack, it is also possible to have the mechanism of similar movement needs for other, all within protection domain of the present utility model.Wherein the maximum flip angle of upper plate 1 is required to be determined by actual motion, and the present embodiment is used for hydraulic jack, and according to its loaded and hydraulic cylinder of institute relation between axial, maximum flip angle is 80 °.
