Description
Technical field
The utility model relates to a kind of jib lubbing mechanism, also relates to the rotary drilling rig that this jib lubbing mechanism is housed.
Background technology
Rotary drilling rig is the piling machinery commonly used that is used for the castinplace pile drilling construction at the pile foundation engineering scene.Jib lubbing mechanism is its critical component, is used for connecting car body and rig equipment.The stability that mast supports during the rising and falling and work of mast all will guarantee by jib lubbing mechanism.
As depicted in figs. 1 and 2, the jib lubbing mechanism of existing rotary drilling rig comprises a swing arm 6 ', two connecting rods 2 ', luffing hydraulic cylinder 1 ', corner block 3 ' and two mast hydraulic cylinders 5 '.The top and bottom of swing arm 6 ' are articulated in the first angle part A ' of corner block and the top D ' of car body 8 ' respectively, the top and bottom of 2 connecting rods are articulated in the second angle part B ' of corner block and the lower part E ' of car body 8 ' respectively, the lower end of luffing hydraulic cylinder 1 ' is articulated in the lower part E ' of car body 8 ', hollow out place 7 ' and be hinged on swing arm on it, form deformable parallelogram sturcutre thus by the luffing Driven by Hydraulic Cylinder.The upper end of two mast hydraulic cylinders 5 ' is articulated on the same plane of mast 4 ', and the first angle part A ' that the lower end is articulated in corner block 3 ' locates, and forms the inverted v-shaped structure that supports mast.When work, the luffing hydraulic cylinder stretches and realizes rising and falling of mast, the flexible verticality that is used for regulating mast of mast hydraulic cylinder.
Yet in engineering practice, there are a series of problems in above-mentioned jib lubbing mechanism.At first, when work, the less stable of equipment.Secondly, the reliability of this jib lubbing mechanism is poor, and each hinged place goes wrong easily.Once more, for big-and-middle-sized rotary drilling rig, for satisfying the requirement of power, the volume of luffing hydraulic cylinder and mast hydraulic cylinder can constantly increase.At last, in when transportation, the height of entire equipment is still higher relatively, especially along with the increase of unit type.
Summary of the invention
In order to address the above problem, the inventor has anatomized the jib lubbing mechanism in the existing rotary drilling rig.Find that the problems referred to above are mainly caused by following factors.The first, there are two connecting rods in the jib lubbing mechanism, thereby four pin joints are arranged, the pin joint in the mechanism is many more, and it is stable that mechanism is not easy to keep more.The upper end of the second, two mast hydraulic cylinder is articulated in the same one side of mast and almost on one point, this is good inadequately for keeping the stability of mast on left and right directions.The 3rd, when two mast hydraulic cylinders are the inverted V-shape layout, according to the mechanics principle analysis, shown in Fig. 7 (1), the active force f ' of mast hydraulic cylinder is broken down into three component f ' x, f ' y, f ' z in space force system, and rising and falling of mast 4 ' only realized by f ' y, f ' z, and promptly the horizontal direction component f ' x of two mast hydraulic cylinders cancels out each other, and makes idle work.The 4th, only a luffing hydraulic cylinder is difficult to deal with the demand of big-and-middle-sized rotary drilling rig to power.The 5th, luffing hydraulic cylinder and swing arm are in the same vertical plane, locate 7 ', can not make the height of equipment reduce to minimum though make the top of luffing hydraulic cylinder can be hidden in hollowing out of swing arm in transportation.The 6th, after the swing arm process hollows out, weakened.If want to increase intensity, must strengthen the size of swing arm.And the structure of swing arm becomes, and complexity is difficult processes.
On the basis of further investigation, the inventor proposes following jib lubbing mechanism.
A kind of jib lubbing mechanism that is used for rotary drilling rig comprises swing arm, bottom connector, three angle connectors, luffing hydraulic cylinder and two mast hydraulic cylinders; Described top and bottom of going up swing arm are articulated between first left comer of described three angle connectors and first right corner respectively and between the upper left and upper right portion of car body, and the top and bottom of described bottom connector are articulated between second left comer of described three angle connectors and second right corner respectively and between the bottom left section and lower right-most portion of car body; Described bottom connector is single one connector; Described luffing hydraulic cylinder is two hydraulic cylinders that are arranged in parallel, the top and bottom of one of them are articulated in first left comer of described three angle connectors and the bottom left section of car body respectively, and another top and bottom are articulated in first right corner of described three angle connectors and the lower right-most portion of car body respectively.
Preferably, described bottom connector is the parallelepiped of two ends rounding.With improvement, described parallelepiped is the welding body.
It is alternatively, described that upward swing arm is identical with described bottom connector structure.
Further preferably, the lower end of described two mast hydraulic cylinders is articulated in first left comer and first right corner of described three angle connectors respectively, and the upper end of described two mast hydraulic cylinders is articulated in the both sides of mast respectively, thereby two mast hydraulic cylinders are parallel to each other.
In above-mentioned jib lubbing mechanism, replace connecting rod in original design with the connector of one, reduced pin joint, mechanism is simply compact, more importantly is the stability when having guaranteed equipment work well.In addition, the connector of this one is as the welding body, and manufacturing process is simple, and the load ability is strong.
Two identical luffing hydraulic cylinders are arranged in parallel in connector both sides, bottom and replace a luffing hydraulic cylinder in original design, thereby satisfy big-and-middle-sized rotary drilling rig fully to the requirement of power and the stability can guarantee the mast operation time.Two masts are arranged in parallel in the both sides of bottom connector, can not occur the phenomenon that luffing hydraulic cylinder and swing arm hinder when falling mast, thereby reduce the shipping height of equipment well.This arrangement compactness is easy to installing/dismounting, is easy to maintaining.
Moreover, the upper end of mast hydraulic cylinder is articulated in the left and right sides of mast respectively, and be arranged in parallel, also be in simultaneously the both sides of swing arm, thereby bring such advantage: 1) two pin joints being connected with mast of mast hydraulic cylinder are arranged in the mast left and right sides, the degree of freedom of mast can be better limited, the easy to adjust simple and easy of mast verticality can be made in the space; 2) according to mechanics principle, the active force of mast hydraulic cylinder does not have component in the x direction as can be seen shown in Fig. 7 (2), and is laborsaving when the V-shape of promptly comparing previous design is arranged.3) the upper end hinged securement of two mast hydraulic cylinders is in the swing arm both sides, and promptly the mast hydraulic cylinder can not limit the reduction of mast height when mast fell, and the equipment shipping height of making is reduced to minimum.
The utility model also proposes to be equipped with the rotary drilling rig of above-mentioned jib lubbing mechanism.
