Abstract
The utility model discloses a lifting and pulling gate type machine cover for a crawler crane. The lifting and pulling gate type machine cover comprises a skeleton which consists of a back frame, a lower frame, a plurality of upper cross beams and a plurality of front vertical beams, which are connected with one another, and gaps are remained among the upper cross beams and the front vertical beams; a plurality of upper gate plates of which the back two sides are built on the upper cross beams are arranged on the upper cross beams at intervals; a plurality of front gate plates of which the back two sides prop against on the front vertical beams and the outer sides of the front gate plates are provided with locking devices are arranged in the front of the front vertical beams at intervals; the upper ends of the front gate plates are connected with the front ends of the upper gate plates by folding edges, and the back ends of the upper gate plates are connected with the upper end of the back frame by the folding edges; and air springs are connected between the front ends at the back two sides of the upper gate plates and the side faces of the upper cross beams. The door plates of the lifting and pulling gate type machine cover are outer covers and lifting and pulling gate type machine cover gates, the outer covers can be wholly opened when the lifting and pulling gate type machine cover gates are opened, and the open degree of the machine cover gates can be greatly improved compared with that of the conventional machine cover gates, so that a maintenance space can be enlarged; and a maintenance action of an operator can not be limited, so that the work efficiency can be improved, and the maintenance cost can be correspondingly reduced.
Description
One, technical field
The utility model belongs to crawler crane accessory technical field, is specifically related to a kind of crawler crane and lifts the gate-type hood.
Two, background technology
Existing crawler crane hood is made of skeleton and upper, front outer cover, and front outer cover have split or on open type hood door.This kind hood door belongs to the wicket that is located on the front outer cover, and unlimited degree is less, causes service clearance little, and operator's service action is restricted, and operating efficiency reduces, the corresponding raising of maintenance cost.If the hood inner component must be taken out during maintenance, must first hood all be pulled down, again parts are taken out, to waste time and energy, labour intensity is larger.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, reasonable in design, opens wide degree large, need not hood is pulled down entirely, the crawler crane that parts take out can be lifted the gate-type hood.
For achieving the above object, the technical scheme that the utility model is taked is: this hood comprises the skeleton that is made of rear frame, underframe and some interconnective entablatrances and front vertical beam, all leaves the interval between the entablatrance and between the front vertical beam; Be characterized in: the entablatrance interval is provided with both sides, the back side and rides over door-plate on the entablatrance several; Be provided with several front doors that both sides, the back side lean against on the front vertical beam, the outside is provided with latching device before the front vertical beam interval; The upper end of front door is connected by folding with the front end of upper door-plate, and the rear end of upper door-plate is connected by folding with the rear frame upper end; Be connected with gas spring between the front end of backboard face both sides and the entablatrance side to the doorstep.
When opening hood, open first latching device, by gas spring upper door-plate is upwards lifted, upper door-plate is upwards mentioned around folding, and by folding front door is mentioned, until after reaching the gas spring end position, upper door-plate is propped by gas spring, and the lower end of front door stands on the entablatrance.Because door-plate of the present utility model namely is that outer cover is again to lift gate-type hood door, outer cover can all open wide when opening, the more traditional hood door of unlimited degree is greatly improved, increased service clearance, operator's service action can not be restricted, improved operating efficiency, the corresponding reduction of maintenance cost.Simultaneously, also need not hood is pulled down, parts can be taken out maintenance, time saving and energy saving, labour intensity is low.The utility model is simple in structure, reasonable in design, is skillfully constructed, and has filled up the blank of this type of hood, is worth applying widely.
Four, description of drawings
Fig. 1 is the structural representation of the utility model when closing;
Structural representation when Fig. 2 is the utility model unlatching;
Fig. 3 is the inner connection diagram of the utility model.
Five, the specific embodiment
As shown in the figure, this hood comprise by rear frame 12, underframe 13, interconnective upper left frame beam 6 and left front vertical beam 9, interconnective middle entablatrance 7 and in before the skeleton that consists of of vertical beam 10, interconnective upper right crossbeam 8 and right front vertical beam 11.Between upper left frame beam 6 and the middle entablatrance 7, between middle entablatrance 7 and the upper right crossbeam 8, left front vertical beam 9 and in before between the vertical beam 10 and in before all leave the interval between vertical beam 10 and the right front vertical beam 11.Be respectively equipped with both sides, the back side on the entablatrance interval and ride over left and right upper door- plate 1,2 on upper left crossbeam 6 and upper center member 7 and upper center member 7 and the upper right crossbeam 8.Be respectively equipped with before the front vertical beam interval both sides, the back side lean against left front vertical beam 9 and in before vertical beam 10 and in before left and right front door 3,4 on vertical beam 10 and the right front vertical beam 11.Left and right front door 3,4 the outside are provided with latching device 5, and this latching device 5 can be door lock.Left and right front door 3,4 upper end are connected by folding 15 with left and right upper door- plate 1,2 front end respectively.Left and right upper door- plate 1,2 rear end are connected by folding 16 with the rear frame upper end.The front end of both sides, upper left door-plate 1 back side is connected with gas spring 14 respectively and between upper left frame beam 6 and the middle entablatrance 7; The front end of both sides, upper right door-plate 2 back side is connected with gas spring 14 respectively and between middle entablatrance 7 and the upper right crossbeam 8.For making things convenient for door-plate to reset, also be provided with attacker 17 in the front door outside.
