The specific embodiment
As shown in Figure 1, the vehicle-mounted lifting device of the utility model simple type installs realization additional on two types of car chassiss 23.
Like Fig. 1～shown in Figure 7, be fixed with a fixed bearing 9 on two types of car chassiss 23.Fixed bearing 9 bottoms are through hinge 11 hinged I number following lifting arm 8, and top is through hinge 12 hinged II number following lifting arm 7.On the bottom axis hole of link span 5, II number following lifting arm 7 other ends were hinged on the middle and lower part axis hole of middle link span 5 through hinge 13 in the middle of I number following lifting arm 8 other ends were hinged on through hinge 14.The middle and upper part axis hole of middle link span 5 number is gone up lifting arm 3 through hinge 15 hinged III, and upper gland number goes up lifting arm 2 through hinge 16 hinged IV.It is hinged through hinge 17 and upper end fixed platform 1 that III number goes up lifting arm 3 other ends, and it is hinged through hinge 18 and upper end fixed platform 1 that IV number goes up lifting arm 2 other ends.The middle part that III number goes up lifting arm 3 is provided with a connecting seat 20, and Connection Block 20 is connected with the hydraulic ram 4 of hydraulic efficiency pressure system, and hydraulic ram 4 lower ends are connected with Connection Block 21 on the middle link span 5.I number following lifting arm 8 is provided with a Triangulum 19.III number go up lifting arm 3 with the hinged drive link 6 in the termination of middle link span 5 junctions, the Triangulum 19 of drive link 6 other ends and I number following lifting arm 8 is hinged.In the utility model, each node location all is to match with axle sleeve through axle to be connected.Each node place axle is that the surface of revolution contacts with axle sleeve, does cliding friction.
Referring to Fig. 1.In the vehicle-mounted lifting device of the simple type of the utility model, III number last lifting arm 3, IV number last lifting arm 2, middle link span 5 and upper end fixed platform 1 four constitute big four connecting rod parallel mechanisms; Number following lifting arm of number following lifting arm of I 8, II 7, middle link span 5 and fixed bearing 9 four constitute little four connecting rod parallel mechanisms.Big four connecting rod parallel mechanisms are connected through drive link 6 and little four connecting rod parallel mechanisms, and the two has generation and oppositely directed each other rotary motion trace simultaneously separately.
Referring to Fig. 1.The vehicle-mounted lifting device of the simple type of the utility model, I number following lifting arm 8 is provided with a mechanical locking 10; II number following lifting arm 7 is provided with a mechanical locking secondary 22.Machinery locking secondary 22 constitutes latching device.When mechanical locking 10 and mechanical locking secondary 22 fit to a time-out, just can carry out mechanical interlocking.The utility model also is provided with hydraulic locking apparatus, and hydraulic locking apparatus is by hand change over valve control locking.Two kinds of Locking Devices of the utility model are worked simultaneously, and mechanical lock is the safety after the assurance expansion when evolutionary operation, and hydraulic locking apparatus is also worked simultaneously.Vehicle ' process or do not have under the situation of lifting operation lifting device is regained, and the locking shelves are replaced in the operation of hydraulic efficiency pressure system hand change over valve get final product.
Referring to Fig. 1.When hydraulic ram 4 stretches out; Will produce corresponding thrust to III number last lifting arm 3; Owing to III number last lifting arm 3 lower ends are connected with middle link span 5, can produce to rotatablely move, so III number last lifting arm 3 is that centre of gration is done rotatablely moving of making progress with these connecting joint; IV number goes up lifting arm 2 because number to go up lifting arm 3 with III be parallel four connecting rod annexations, and when III number went up lifting arm 3 and does rotatablely moving upwards, IV number went up lifting arm 2 and also follows suit and move in the same way.Meanwhile; Because III number last lifting arm 3 lower ends are connected with trace 6; Trace 6 lower ends lean on the Triangulum 19 of upper end position to be connected with I number following lifting arm 8 again; I number following lifting arm 8 upper ends are connected with middle link span 5, can be centre of gration with this node of middle link span 5 therefore, under the promotion of trace 6, do relative moving downward.Because I number following lifting arm 8 lower ends are connected with fixed bearing 9, fixed bearing 9 is fixed, and under the mutual action of power, I number following lifting arm 8 will be that centre of gration is done and III number upward lifting arm 3 opposite rotatablely moving with the lower end connecting joint.II number following lifting arm 7 will be followed I number following lifting arm 8 and done rotatablely moving in the same way of parallel relation.When III number went up lifting arm 3, IV and number goes up lifting arm 2 and give rise to vertical position, mechanical locking 10 fit together with mechanical locking secondary 22, and mechanical locking 10 and mechanical locking secondary 22 are locked together, and it is firm that the vehicle-mounted lifting device of simple type is stablized.So just accomplished the lifting operation of lifting device.
It is opposite with said process that the lifting arm of the vehicle-mounted lifting device of simple type of the utility model is regained process.
The vehicle-mounted lifting device of the simple type of the utility model is applicable to that as the particular private device signal receives and sends with antenna, light weight radar unit (need slewing arrangement be installed in the upper end fixed platform when radar is installed).
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
