Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
As depicted in figs. 1 and 2, the present invention provides a kind of driver's cabin protective device, including supporting element 10, installation part 20 and
One protector 30, supporting element 10 and installation part 20 are used to be fixed on driver's cabin；The bottom of supporting element 10 and the first protector 30
Portion's clamping, supporting element 10 is to abut when closed according to preset direction with the first protector 30 to prevent 30 turns of the first protector
It is dynamic to open；The side of first protector 30 is rotatably assorted with installation part 20, and the first protector 30 is being preset along installation part 20
It is slidably matched on direction.
Driver's cabin protective device provided in this embodiment is mounted on the driver's cabin of engineering machinery, opening first is not needed
When protector 30, the bottom of the first protector 30 and supporting element 10 are clamped, and 10 one side of supporting element can be to the first protector 30
It is supported, avoids the first protector 30 from loosening in engineering machine in working process and fall, to improve the first protector 30
Reliability and stability；On the other hand, supporting element 10 can stop the first protector 30 to be opened, and avoid the first protector 30 in work
The loosening of journey machine work process rotates and opens and lead to not realize and protect to driver's cabin, and it is anti-to further increase first
The reliability and stability of guard 30.
When needing to open the first protector 30, driving 30 relative support 10 of the first protector slides on preset direction
Movement to be detached from supporting element 10, and then releases supporting element 10 in the abutting locking action of preset direction, at this time supporting element
10 no longer play barrier effect to the first protector, again by the first protector to far from driver's cabin in this way after sliding unlocking motion
Direction rotation be openable first protector.Driver's cabin protective device provided by the invention is reliable and stable, is easy to use.
Wherein, the structure type of the first protector 30 can be a variety of, such as: protective plate, protective net or shielded frame
Etc. can be to the structure that driver's cabin is protected.
The shape of first protector 30 can be arranged according to the structure of specific driver's cabin, such as conventional quadrangle, specifically
Ground rectangle as shown in Figure 1.
In the present embodiment, installation part 20 is fixed on driver's cabin, and the first protector 30 is flexibly connected with installation part 20, is passed through

The structure type of part 60 can be a variety of, such as: as shown in figure 4, supporting element 10 is connect with the bottom of the first protector 30, with right
First protector 30 is supported and limits, and the side of the first protector 30 is flexibly connected with installation part 20, the side and the
The bottom of one protector 30 is opposite, that is, the top of the first protector 30, specifically, drives as shown in Figure 1, installation part 20 is located at
The top for sailing room, according to the first protector 30 by with 10 phase of supporting element arrive to supporting element 10 be detached from need move up away from
From the setting sliding slot 21 on installation part 20, sliding slot 21 is two, and two sliding slots are oppositely arranged, and the both ends of sliding slot, which are respectively set, to be turned
Dynamic hole, the top of the first protector 30 are connected with connecting shaft 33, and the both ends of connecting shaft are slidably installed in respectively in two sliding slots, when first
When protector 30 is in close state, the first protector 30 offsets with supporting element 10, and the end of connecting shaft is located at sliding slot lower end
In rotation hole, when needing to open the first protector 30,30 upward sliding of the first protector is driven, the end of connecting shaft is in sliding slot
Interior sliding can be rotated up the first protector 30, so that the first protector 30 until in the rotation hole of arrival sliding slot upper end at this time
It is in the open state, the first protector 30 is closed with opening procedure on the contrary, details are not described herein.
Optionally, as shown in figure 5, supporting element 10 is connect with the bottom of the first protector 30, with to the first protector 30 into
Row support and limitation, the side of the first protector 30 are flexibly connected with installation part 20, the bottom of the side and the first protector 30
Portion is adjacent, that is to say, that and 30 left side of the first protector is opened or the right side is opened, this setup, facilitates the opening of the first protector 30,
It is convenient to use.
In such cases, connecting column can be fixedly installed on installation part 20, connector sleeve is arranged in the side of the first protector 30,
Connector sleeve is set on connecting column, and connector sleeve can slide on connecting column, also rotatable.
Optionally, as shown in figure 5, connector 60 includes pin shaft 61 and pairs of hinge, one in pairs of hinge is fixed on
On first protector 30, which may be defined as hinge 62, another is fixed on installation part 20, which may be defined as down
Hinge 63；One end of pin shaft 61 is fixedly connected with upper hinge 62, and the other end of pin shaft 61 rotates and is slidably connected at lower jaw 63
Axis hole in.
In the present embodiment, when needing to open the first protector 30, drive the first protector 30 to separate supporting element 10
Direction movement, upper hinge 62 are fixedly connected with the first protector 30, and the upper end of pin shaft 61 is fixedly connected with upper hinge 62, then pin shaft
61 follow the first protector 30 while moving, and the lower end of pin shaft 61 is threaded through always in the axis hole of lower jaw, when the first protector
After 30 are detached from supporting element 10, can be rotated the first protector 30 makes its opening.This movable connection method structure is simple, installation side
Just, the rotation of the first protector 30 is reliable.
Wherein, the flexible connection that the first protector 30 and installation part 20 can be realized by multiple groups hinge structure makes first to prevent
The installation of guard 30 is more reliable more stable.
On above-described embodiment basis, further, when driving the first protector 30 movement, the can be handled by hand handle
One protector 30 is to drag the first protector 30.
Optionally, driver's cabin protective device further includes actuator 70, and actuator 70 is connect with the first protector 30, with driving
First protector, 30 opposite mount 20 slides on preset direction.In the present embodiment, actuator 70 is set to drive first to prevent
Guard 30 moves, and can avoid manually holding its movement of the first protector 30 driving, further facilitates use.
Wherein, actuator 70 may be provided on driver's cabin, it is settable on a mounting board, can also be provided at the second protector 40
On.
The structure type of actuator 70 can be a variety of, such as: actuator 70 be electric telescopic rod, oil cylinder, cylinder or
