Abstract
The invention relates to a lifting door type hood of a crawler crane, and discloses a framework formed by a back frame, a lower frame, and upper cross beams and front stand beams which are mutually connected, wherein gaps are reserved among the upper cross beams and among the front stand beams, a plurality of upper door plates are arranged on the intervals of the upper cross beams, the two sides of the back surfaces of the upper door plates are erected on the upper cross beams, a plurality of front door plates are arranged before the intervals of the front stand beams, the two sides of the back surfaces of the front door plates lean against the front stand beams, the outer sides of the front door plates are provided with locking devices, the upper ends of the front door plates and the front ends of the upper door plates are connected through hinges, the back ends of the upper door plates and the upper end of the back frame are connected through hinges, and air springs are connected between the front ends of the two sides of the back surfaces of the upper door plates and the sides of the upper cross beams. According to the invention, the door plates can be used as an outer cover and a lifting door type hood door, when the door plates are opened, the hood can be fully open, the opening degree is greatly improved compared with the traditional hood, further, the maintenance space is increased, the maintenance action of operators can not be limited, the operation efficiency is improved, and the maintenance cost is correspondingly reduced.
Description
One, technical field
The invention belongs to crawler crane accessory technical field, be specifically related to a kind of crawler crane and lift 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 invention is to provide a kind of simple in structurely, reasonable in design, it is large to open wide degree, 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 present invention takes 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 invention namely is that outer cover is again to lift gate-type hood door, outer cover can all open wide when opening, and the more traditional hood door of unlimited degree is greatly improved, increased service clearance, operator's service action can not be restricted, and has 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 present invention 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 present invention when closing;
Fig. 2 is the structural representation of the present invention when opening;
Fig. 3 is the inner connection diagram of the present invention.
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.
