Abstract
The present invention provides a kind of scissors transversal stretching system, yoke body cradle is fixedly connected on the lifting device of three-dimensional Operation Van, scissor arms front end is hinged on workbench connection frame, rear end is hinged on yoke body cradle, oil cylinder piston end is hinged on oil cylinder front support beam, cylinder bottom end is hinged on oil cylinder rear support beam, and oil cylinder front support beam and oil cylinder rear support beam are respectively welded in scissor arms.It is easy that retraction operation is stretched out when narrow horizontal space carries out side operation to rolling stock, does not need cross track, structure is simple, improves the technical of product, craftsmanship and economy.
Description
Technical field
The invention belongs to mechanical equipment manufacturing field, in particular to three-dimensional Operation Van's scissors transversal stretching system.
Background technique
Three-dimensional Operation Van is mainly used for the spraying, maintenance and assembling work of rolling stock.It requires the vehicle, and there are three freely
Degree: i.e. longitudinal walking, transversal stretching and vertical lift.As shown in Figure 1, longitudinal walking is by longitudinal walking ground wheel and head sheave Lai real
It is existing；Vertical lift is realized by lifting device (such as chain, lead screw)；Transversal stretching is all traditionally by slideway, slide unit Lai real
Existing.There is following shortcoming in this transversal stretching:
1. pair rolling stock carries out needing to retract when the operation of side, when end operation, needs to stretch out.Flexible stroke generally exists
It 1.3 meters or so, then track length is just longer, it requires with enough horizontal spaces.
2. generally using multi-stage expansion to reduce track length, so that structure is extremely complex.Some laterally empty
Between narrow place even cannot achieve.
3. it is accurate that track and slide unit size require, relatively high to welding and requirement on machining accuracy；So increasing technique
Difficulty.
Summary of the invention
Present invention solves the technical problem that being that a kind of structure is simple, the three-dimensional Operation Van that can satisfy narrow horizontal space is cut
Formula transversal stretching system.
The technical solution adopted by the present invention is that: a kind of three-dimensional Operation Van scissors transversal stretching system, yoke body cradle are fixed
It is connected on the lifting device of three-dimensional Operation Van, scissor arms front end is hinged on workbench connection frame, and rear end is hinged on yoke hinge
It connects on frame, oil cylinder piston end is hinged on oil cylinder front support beam, and cylinder bottom end is hinged on oil cylinder rear support beam, oil cylinder front support beam
It is respectively welded in scissor arms with oil cylinder rear support beam.
Scissor arms include interior scissor arms and outer scissor arms, and interior scissor arms and outer scissor arms are 2, interior scissor arms and are cut outside
Yoke is hinged at center.
Oil cylinder front support beam is welded on the center of scissor arms in two.
Oil cylinder rear support beam is welded on the front end of two outer scissor arms.
The invention has the advantages that stretching out retraction operation when narrow horizontal space carries out side operation to rolling stock
Simplicity does not need cross track, and structure is simple, improves the technical of product, craftsmanship and economy.

Appended drawing reference: the outer scissor arms 3- workbench connection frame of scissor arms 22- in 1- yoke body cradle 2- scissor arms 21-
4- oil cylinder front support beam 5- oil cylinder 6- oil cylinder rear support beam 7- workbench 8- lifting device 9- longitudinal direction walking ground wheel 10- is vertical
To walking head sheave
Specific embodiment
The present invention is further explained with reference to the accompanying drawing.
Yoke body cradle 1 is fixed on the lifting device 8 of three-dimensional Operation Van, and 2 front end of scissor arms is hinged on workbench connection
On frame 3, rear end is hinged on yoke body cradle 1, and 5 piston end of oil cylinder is hinged on oil cylinder front support beam 4, and cylinder bottom end is hinged on
On oil cylinder rear support beam 6, oil cylinder front support beam 4 and oil cylinder rear support beam 6 are welded in scissor arms respectively.
Scissor arms 2 include interior scissor arms 21 and outer scissor arms 22, and interior scissor arms 21 and outer scissor arms 22 are 2, described
Interior scissor arms 21 and outer scissor arms 22 are hinged at center.Oil cylinder front support beam 4 is welded on the center of scissor arms 21 in two.Oil cylinder
Rear support beam 6 is welded on the front end of two outer scissor arms 22.
Such as Fig. 1, three-dimensional Operation Van passes through longitudinal walking ground wheel 9 and longitudinal walking head sheave 10 moves longitudinally to job position,
After being elevated to job position by the way that lifting device 8 is vertical, if Fig. 2, Fig. 3 are when needing to cross out operation, 5 piston rod of oil cylinder is stretched
Oil cylinder front support beam 4 and oil cylinder rear support beam 6 is pushed to make 2 top of scissor arms along yoke body cradle 1 and workbench connection frame 3 out
Vertical downslide makes workbench 7 extend laterally into job position；When needing cross-direction shrinkage operation, 5 piston rod of oil cylinder, which is withdrawn, to be pulled
Oil cylinder front support beam 4 and oil cylinder rear support beam 6 make 2 top of scissor arms along yoke body cradle 1 and workbench connection frame 3 it is vertical on
It is sliding, make 7 cross-direction shrinkage of workbench to job position；Complete assignment content.When resting, scissor arms 2 can contract completely
It returns as shown in Figure 1, saving space.
