Abstract
The utility model discloses a swing mechanism of a high safety performance truck mounted crane. The swing mechanism belongs to the technical field of machinery manufacturing and comprises a base, an internal gear ring of a slewing bearing, an external gear ring of the slewing bearing, a rotary disc and a rotary column, wherein a pin hole is formed in the front end and rear end, close to edges, of the rotary disc respectively; a fixed pin bush is mounted at the rear end of the internal gear ring of the slewing bearing; the position of the fixed pin bush is matched with that of one of the pin holes; a safety pin is inserted into one of the pin holes and the fixed pin bush. When the swing mechanism works, the safety pin is taken out, and when the truck mounted crane needs to drive, the safety pin is inserted into the pin hole and the fixed pin bush, so that the swing mechanism is prevented from being damaged due to impact of external forces, and the driving safety is ensured. The swing mechanism can ensure that the truck mounted crane can drive safely on any road, has a simple structure and is reliable in performance.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of truck-mounted crane swing type mechanism.
Background technology
Truck-mounted crane are mounted in the loop wheel machine on walking machine, the swing type mechanism of truck-mounted crane mainly consists of pedestal, pivoting support internally toothed annulus, pivoting support external toothing, rotating disk and rotary column, pedestal is arranged on walking machine, the pivoting support internally toothed annulus connects pedestal, the pivoting support internally toothed annulus coordinates installation with the pivoting support external toothing, and rotary column connects the pivoting support external toothing by rotating disk.Loop wheel machine is arranged on rotary column.Swing type mechanism can rotate by 360 degree, and in plane, the pivoting support external toothing of swing type mechanism, with hydraulic brake system, under normal circumstances, relies on its braking, stops.But truck with loading crane under the crooked-running state, is easy to damage because inertia causes brake equipment, and causes a serious accident.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of truck-mounted crane swing type mechanism of high safety performance.
The scheme of the utility model technical solution problem is to adopt pedestal, pivoting support internally toothed annulus, pivoting support external toothing, rotating disk and rotary column to form the truck-mounted crane swing type mechanism of high safety performance, have respectively a pin-and-hole at the place of keeping to the side, rear and front end of rotating disk, in the rear end of pivoting support internally toothed annulus, fixedly guide is installed, fixedly the guide position is corresponding with pin-and-hole, and pin-and-hole reaches fixedly guide interpolation and enters safety pin.During swing type mechanism work, withdraw from safety pin, when truck with loading crane need to travel, reach fixedly guide interpolation at pin-and-hole and enter safety pin, avoid rotary decelerating mechanism to damage owing to being subject to external impacts, guarantee traffic safety, due to two pin-and-holes being arranged, though be the arm of hoisting crane front or rear, can coordinate and be fixed with fixedly guide and safety pin by one of them pin-and-hole.
The utility model can guarantee that truck with loading crane, in the safety traffic of any road surface, avoids the damage of truck-mounted crane turn-around machine, and is simple in structure, dependable performance.
Description of drawings
Accompanying drawing 1 is cutaway view of the present utility model.
The specific embodiment
The utility model consists of pedestal 1, pivoting support internally toothed annulus 2, pivoting support external toothing 3, rotating disk 4 and rotary column 5, have respectively a pin-and-hole 7 at the place of keeping to the side, rear and front end of rotating disk 4, fixedly guide 6 is installed in the rear end of pivoting support internally toothed annulus 2, fixedly guide 6 positions are corresponding with pin-and-hole 7, and pin-and-hole 7 reaches the fixedly interior insertion safety pin 8 of guide 6.
Claims (1)
1. the truck-mounted crane swing type mechanism of a high safety performance, formed by pedestal, pivoting support internally toothed annulus, pivoting support external toothing, rotating disk and rotary column, it is characterized in that: the place of keeping to the side, rear and front end of rotating disk has respectively a pin-and-hole, in the rear end of pivoting support internally toothed annulus, fixedly guide is installed, fixedly the guide position is corresponding with pin-and-hole, and pin-and-hole reaches fixedly guide interpolation and enters safety pin.
