Description
Technical field
The utility model relates to hoisting and hanging technical field, is specially a kind of understructure of rotary crane.
Background technology
In material handling field, rotary crane is wherein a kind of important handling machinery, it can complete the operations such as feeding, migration, unloading, in equipment of Vessel, rotary crane is main handling machinery, in rotary crane carrying material process, need first arm to be gone to carrying position, then hook is driven to lift material by lifting rope, in hoisting process, owing to slipping up in weight of material reason or operator's operating process, arm can swing because of the rotation of turntable sometimes, affects the lifting of material.
Summary of the invention
In order to solve the problem, the utility model provides a kind of understructure of rotary crane, and its structure is simple, can realize the fixing operation of rotary crane turntable easily, ensures the lifting of material.
Its technical scheme is such: a kind of understructure of rotary crane, it comprises base and turntable, bottom described turntable, rotating disk is installed, described base is connected by surface bearing with described rotating disk, it is characterized in that, described base sidepiece installs locating support, described locating support is installed and is positioned at conplane positional cylinder with described rotating disk, described positional cylinder is along described rotating disk radial arrangement, fixture block is installed in the piston rod end of described positional cylinder, and described rotating disk sidepiece evenly has the draw-in groove that multiple and described fixture block coordinates.
It is further characterized in that, described base sidepiece symmetry installs two described locating supports, and two described locating supports install described positional cylinder respectively;
Described locating support is installed location and installation groove, the cylinder body of described positional cylinder is fixedly installed in described location and installation groove;
Described fixture block is V-arrangement fixture block, and described draw-in groove is the V-arrangement draw-in groove coordinated with described V-arrangement fixture block;
Described rotating disk outside portion evenly has 180 described draw-in grooves.
After adopting structure of the present utility model, turntable goes to Hoisting Position, the piston rod of positional cylinder stretches out, make the fixture block inlay card of the piston rod end of positional cylinder in the draw-in groove of rotating disk sidepiece, fixture block coordinates with draw-in groove and clamps, its structure is simple, can realize the fixing operation of rotary crane turntable easily, ensures the lifting of material.
Accompanying drawing explanation
Fig. 1 is the utility model structural front view;
Fig. 2 is the utility model structure birds-eye view.
Detailed description of the invention
See Fig. 1, shown in Fig. 2, a understructure for rotary crane, it comprises base 1 and turntable 2, installs rotating disk 3 bottom turntable 2, base 1 is connected by surface bearing 4 with rotating disk 3, base 1 sidepiece installs locating support 5, and locating support 5 is installed and is positioned at conplane positional cylinder 6 with rotating disk 3, positional cylinder 6 is along rotating disk 3 radial arrangement, fixture block 7 is installed in the piston rod end of positional cylinder 6, and rotating disk 3 sidepiece evenly has multiple draw-in groove 8 coordinated with fixture block 7; Base 1 sidepiece symmetry is installed on two locating supports, 5, two locating supports 5 and is installed positional cylinder 6 respectively, can be realized the location of turntable by the positional cylinder of both sides better; Locating support 5 is installed location and installation groove 5-1, the cylinder body of positional cylinder 6 is fixedly installed in location and installation groove 5-1, the cooperation of location and installation groove 5-1 and positional cylinder 6 makes positional cylinder 6 can the location of locating turntable 3 better, prevents the stressed excessive damage reason location support 5 of positional cylinder 6 and positional cylinder 6 junction; Fixture block 7 is V-arrangement fixture block, and draw-in groove 8 is the V-arrangement draw-in groove coordinated with V-arrangement fixture block, and V-arrangement fixture block and V-arrangement notch simply, can conveniently realize coordinating clamping; Rotating disk 3 sidepiece evenly has 180 draw-in grooves 8, can realize accurately locating better.
