Abstract
A kind of engineering machinery driving cabin elevating mechanism safety device, is shown in accompanying drawing, and conventional cab lift mechanism is made up of driver's cabin, upper connecting rod mechanism, rear support, hoist cylinder, lower link mechanism, driver's cabin base etc..In order to prevent the accidental damage of hoist cylinder hydraulic lock or maloperation when driver's cabin base bottom repairs, driver's cabin base is caused to fall suddenly, weigh maintenance personal wounded, therefore mechanical locking is increased between upper connecting rod mechanism of cab lift mechanism and lower link mechanism, it is made up of respectively fixing axle, connecting plate, packing ring and split pin, this device is locked during maintenance, ensures that driver's cabin base does not fall, it is ensured that the personal safety of maintenance personal.
Description
Technical field
A kind of crane for being used in and carrying cab lift mechanism is the utility model is related to, is to be related to one kind specifically
With the safety device on hoisting box's elevating mechanism.
Background technology
In order to facilitate lifting cargo, increase driver's field of view, therefore a kind of driver's cabin liter can be designed on crane
Descending mechanism increases field of view during driver's lifting cargo to adjust cab heights.Existing cab lift mechanism group
Into mainly including：Driver's cabin base, upper connecting rod mechanism, lower link mechanism, rear support, hoist cylinder etc..Driver's cabin base bottom
There are many fluid pressure lines and electric appliance circuits, when sailing the rise maintenance of room base bottom, operating personnel need to tie up in driver's cabin base bottom
Repair, hoist cylinder hydraulic lock accidental damage or maloperation during to prevent maintenance, causing driver's cabin base to fall suddenly, weighing maintenance wounded
Personnel, therefore increase mechanical locking between upper connecting rod mechanism of cab lift mechanism and lower link mechanism, will during maintenance
This device is locked, and ensures that driver's cabin base does not fall, it is ensured that the personal safety of maintenance personal.
Utility model content
Problem to be solved in the utility model is to provide a kind of cab lift mechanism safety device, so that it is guaranteed that
The personal safety of the maintenance personal of driver's cabin base bottom.
In order to solve the above technical problems, technical scheme is used by the utility model：A kind of engineering machinery driving cabin liter
Descending mechanism safety device, including fixing axle 1, the fixing axle 1 totally three, two are welded in lower link mechanism, a welding
In upper connecting rod mechanism, when needing to repair in cab bottom, between connecting plate 2 is connected into upper and lower strut, while cushioning circle 3
And split pin 4 is fixed, to reach the possibility that limitation driver's cabin base falls, when being not required to maintenance, connecting plate 2 can be connected in down
On connecting rod and cushioning circle 3 and split pin 4 are fixed.
The beneficial effects of the utility model are as follows：
Safe locking device of the present utility model, it is simple in construction easy to operate, it is easy for installation, and maintenance personal is at driver's cabin bottom
Personal safety is can ensure that during seat bottom servicing.
Brief description of the drawings
Accompanying drawing is the cab lift structural scheme of mechanism that the utility model increases safety device.
Embodiment
Accompanying drawing is the cab lift structural scheme of mechanism that the utility model increases safety device.To each several part explanation in accompanying drawing
It is as follows
The rear support of 1 fixing axle, 2 connecting plate, 3 packing ring, 4 split pin 5
The upper connecting rod mechanism of 6 hoist cylinder, 7 lower link mechanism, 8 driver's cabin base, 9 driver's cabin 10
As shown in drawings, cab lift mechanism is commonly used by driver's cabin 9, upper connecting rod mechanism 10, rear support 5, hoist cylinder
6th, lower link mechanism 7, driver's cabin base 8 etc. form.It is as follows to increase safe locking device：Fixing axle 1, the fixing axle 1 totally three,
Two are welded in lower link mechanism 7, and one is welded in upper connecting rod mechanism 10, will when needing to repair in cab bottom
Connecting plate 2 is connected between upper connecting rod mechanism 10 and lower link mechanism 7, while cushioning circle 3 and split pin 4 are fixed, to reach
The possibility for preventing the damage of the hydraulic lock of hoist cylinder 6 or maloperation and causing driver's cabin base 8 to fall suddenly, when being not required to maintenance,
Connecting plate 2 can be connected in lower link mechanism 7 and cushioning circle 3 and split pin 4 are fixed.
Claims (1)
- A kind of 1. engineering machinery driving cabin elevating mechanism safety device, it is characterised in that：By fixing axle, connecting plate, packing ring, open Mouth sells part combination into safety device；Each part annexation is：Fixing axle totally three, two are welded in lower link mechanism, One is welded in upper connecting rod mechanism, and when needing to repair in cab bottom, connecting plate is connected into upper connecting rod mechanism and lower company Between linkage, while cushioning circle and split pin are fixed, and lock cab lift mechanism upper connecting rod and lower link operation, from And cause driver's cabin base to fall suddenly due to the accidental damage of hoist cylinder hydraulic lock or maloperation when preventing from repairing, weigh dimension wounded Repair personnel.
