Abstract
The invention relates to a cab of an engineering machine, which is provided with an ROPS (roll-over protection system) and aims to overcome the shortcoming that a thick and heavy steel plate is welded at the bottom an existing cab to be used as a mounting support so that steel consumption is high. The cab comprises a framework, the framework consists of upright columns and transverse framework components, the upright columns are vertically arranged, the transverse framework components are positioned below the middles of the upright columns, vertical through holes are disposed on the transverses framework components and are adjacent to the upright columns, and threaded connecting components which are used for being connected with mounting bots of the cab in a threaded manner are arranged at the upper ends of the through holes or disposed in the through holes. During installation, the threaded connecting components are connected with the mounting bolts of the cab so that the cab is mounted without welding the thick and heavy steel plate at the bottom of the cab, steel materials are saved, and manufacturing cost is reduced.
Description
Technical field
The present invention relates to a kind of operator's compartment, particularly a kind of engineering machinery driving cabin.
Technical background
Engineering machinery driving cabin is a separate part, and it needs reliably to be connected with vehicle frame; Existing construction machinery and equipment contains the shaped steel skeleton mostly; Operator's compartment is that the shaped steel skeleton connects to ground when installing; The shaped steel skeleton shows as roll protection structure (ROPS) sometimes; This moment, it will have enough Joint strenghts with vehicle frame, and the back operator's compartment that prevents to overturn separates with vehicle frame and the protection structure that causes rolling can not normally be brought into play the effect of protecting chaufeur.The existing operator's compartment that contains the shaped steel skeleton all is that shaped steel also welds plate iron on the skeleton bottom in the operator's compartment bottom, and the boring tapping is threaded with the hold-down bolt of operator's compartment on plate iron, realizes the fixed installation of operator's compartment.There are many shortcomings in this installation method at operator's compartment skeleton bottom welding plate iron, and for example the weld seam of the welding of plate iron and operator's compartment skeleton is long, and requirements for quality is high; The rigidity of plate iron is big; It and operator's compartment skeleton bonded assembly weld edge stress value are very high, because plate iron is thicker big, makes this operator's compartment and not only will expend more steel more in addition; Increase manufacturing cost, also increase the weight of machine simultaneously.
Summary of the invention
The objective of the invention is to needs welding plate iron is installed and is caused welding quality to require height, the big shortcoming of cost and a kind of simple in structure, the engineering machinery driving cabin that can save steel is provided to existing engineering machinery driving cabin.
Technical scheme of the present invention is achieved in that a kind of engineering machinery driving cabin of structure; It comprises skeleton; Skeleton comprises the column and the horizontal frame member that is positioned at below the column middle part of vertical setting; Horizontal frame member be provided with upwards, with the construction machinery and equipment vehicle frame on the corresponding through hole of operator's compartment erection support, be provided with in the upper end of through hole or the through hole and be used for the parts that are threaded that are threaded with the operator's compartment hold-down bolt.In the present invention, the parts that are threaded are set in the upper end of through hole or the through hole are threaded, thereby can save thick and heavy steel plate, save steel, have the advantage of simple in structure and easy manufacturing with the hold-down bolt of operator's compartment.
In the present invention; The parts that are threaded can be the installation shaft that is positioned at through hole; The two ends of installation shaft are welded to connect with horizontal frame member, and the lower surface of installation shaft is provided with and is used for the tapped bore that cooperates with the operator's compartment hold-down bolt, when operator's compartment and vehicle frame installation; The operator's compartment hold-down bolt is threaded with installation shaft, to realize the installation of operator's compartment.Be convenient and make, installation shaft can select steel pipe for use and in endoporus tapping form.In order to strengthen the Joint strenght of installation shaft and horizontal frame member; The upper side of installation shaft has annular protrusion; The diameter of annular protrusion is greater than the diameter of through hole, and the bottom surface of annular protrusion is connected with horizontal frame member contact, side and laterally frame member welding.Because installation shaft mainly is the pulling force that receives the operator's compartment hold-down bolt downward, so being raised with on the installation shaft helps strengthen the Joint strenght of installation shaft and horizontal frame member.In the present invention, the parts that are threaded can also be the nuts that is positioned at the through hole upper end, nut and laterally frame member welding, and when operator's compartment and vehicle frame installation, nut is threaded with the operator's compartment hold-down bolt that passes through hole, to realize the installation of operator's compartment.
Contact the bonded assembly backing plate when in the present invention, the lower end of through hole is provided with and is used for operator's compartment and installs with bumper.Because laterally the size of frame member is usually all less than the size of bumper; When therefore operator's compartment was installed, laterally frame member only contacted with the part area of bumper upper surface, causes the application force that acts on the bumper excessive; Lower end at through hole is provided with backing plate; Can make operator's compartment contact, act on the pressure on the bumper upper surface unit area, improve the performance of bumper thereby reduce with the upper surface gross area of bumper.
In the present invention, laterally frame member can be to be positioned at the crossbeam that the column middle and lower part connects column, and through hole is arranged on the crossbeam.Reduce the influence of intensity in order to reduce crossbeam because of establishing through hole in addition, crossbeam is welded with pasting board in the both sides that the through hole position is set.Simultaneously; Through hole also can be arranged on the position of adjacent stud on the horizontal frame member; Crossbeam and column junction are welded with brace panel; Through hole is arranged on the below of brace panel, because the booster action of brace panel is arranged, so this measure also can reduce crossbeam and reduces the influence of intensity because of establishing through hole.The brace panel of crossbeam and the welding of column junction can be a U-lag formula brace panel.
In the present invention, laterally frame member can also be to comprise that the crossbeam that the crossbeam that connects column and two crossbeam phase proximity connect two crossbeams connects brace panel, and through hole is arranged on the crossbeam connection brace panel.It is perforate on the crossbeam that this technical scheme can be avoided the main framing at operator's compartment, reduces the influence of operator's compartment frame strength because of perforate.
Operator's compartment when operator's compartment in the present invention can also sedimentation be installed also promptly below the middle part of column, is provided with horizontal frame member more than the root, the through hole and the parts that are threaded can be arranged on this and locate on the horizontal frame member.
The beneficial effect that the present invention compared with prior art has: directly on the horizontal frame member of operator's compartment, establish through hole and the parts that are threaded that are connected the operator's compartment hold-down bolt in the present invention; Avoided existing operator's compartment to add the thick and heavy steel plate of weldering in its bottom; Thereby has low manufacture difficulty; Save simultaneously steel again, reduce the advantage of manufacturing cost.
