Abstract
The utility model provides a novel lorry-mounted crane. The novel lorry-mounted crane comprises a telescopic lifting arm, a rotary mechanism, a bottom frame, supporting legs, supporting leg oil cylinders, a hydraulic oil pipe for supplying oil to the supporting leg oil cylinders, a lifting mechanism, a bridge type frame and a hydraulic system, and is characterized in that the rotary mechanism comprises a hydraulic motor and a turntable; and the hydraulic motor is used for driving the turntable to rotate through a single-stage worm gear directly. According to the novel lorry-mounted crane, the rotary mechanism adopts the design that the turntable is directly driven by the hydraulic motor through the single-stage worm gear, few parts are used, the transmission process is simple, and in addition, the rotary mechanism has the characteristics of good self-locking property and no impact due to the transmission characteristics of the worm gear.
Description
Technical field
The utility model relates to a kind of elevator machinery, is specifically related to a kind of Novel lorry-mounted crane.
Background technology
Lorry-mounted crane refers to be installed on the automobile card chassis that possesses the loading function, and the elevator machinery of vertical-lift and horizontal carrying heavy goods within the specific limits, this hoisting crane have flexible operation, characteristics that manoevreability is good.The swing type mechanism of existing lorry-mounted crane is comprised of the revolution rolling bearing of HM Hydraulic Motor, multi-stage speed reducer and primary cylinder gear transmission etc.Rolled through the fixed gear ring that the wraparound of multi-stage gear retarder drive revolution miniature gears turns in the support by HM Hydraulic Motor, impel rotation of rotary table.Retarder adopts spur gear transmission, Planetary Gear Transmission and their combination thereof.In addition, at high speed shaft mechanical brake is housed.This swing type mechanism complex structure, fault rate is higher, and tolerance clearance is large, exists revolution to impact.
In addition, existing lorry-mounted crane push-and-pull leg structure hydraulic oil pipe is external, and easily scratching is damaged, and safety there is not guarantee.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of Novel lorry-mounted crane, and its swing type mechanism is simple in structure, revolution is steady, self-locking performance is good, nothing is impacted.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of Novel lorry-mounted crane, comprise telescoping boom, swing type mechanism, underframe, supporting leg, support oil cylinder, to hydraulic oil pipe, lifting mechanism, bridge type frame and the hydraulic efficiency pressure system of support oil cylinder fuel feeding, it is characterized in that: swing type mechanism comprises HM Hydraulic Motor and turntable, and HM Hydraulic Motor directly drives turntable by the single-stage worm and gear and rotates.
Above-mentioned Novel lorry-mounted crane, the described hydraulic oil pipe of support oil cylinder fuel feeding of giving is built in underframe and the supporting leg.
The design that swing type mechanism of the present utility model adopts HM Hydraulic Motor directly to drive via the single-stage Worm Wheel System, have parts few, transmission is simple, in addition, because of the characteristic of Worm Wheel System, so that swing type mechanism of the present utility model has good, the shock-free characteristics of self-locking performance.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 part-structure schematic diagram.
Fig. 3 is Fig. 1 part-structure schematic diagram.
Fig. 4 is the lateral plan of Fig. 1.
Among the figure: 1 support oil cylinder, 2 hydraulic oil pipes, 3 HM Hydraulic Motor, 4 swing type mechanisms, 5 lifting mechanisms, 6 underframe, 7 supporting legs, 8 bridge type framves, 9 amplitude oil cylinder, 10 telescoping booms.
The specific embodiment
As illustrated in fig. 1 and 2, a kind of Novel lorry-mounted crane, comprise telescoping boom 10, swing type mechanism 4, underframe 6, supporting leg 7, support oil cylinder 1, to hydraulic oil pipe 2, lifting mechanism 5, bridge type frame 8 and the hydraulic efficiency pressure system of support oil cylinder fuel feeding, swing type mechanism comprises HM Hydraulic Motor 3 and turntable, and HM Hydraulic Motor directly drives turntable by the single-stage worm and gear and rotates.
The described hydraulic oil pipe of support oil cylinder fuel feeding of giving is built in underframe and the supporting leg, compares with existing hydraulic oil pipe is external, and built-in hydraulic oil pipe compact conformation, insolation proof, anti-scratching, safety is good.
Lorry-mounted crane is when operation, the power that driving engine transmits out by power takeoff with transmission of power to hydraulic oil pump, hydraulic oil pump provides high-voltage oil liquid to hydraulic efficiency pressure system, many by road valve operation hydraulic efficiency pressure system, hydraulic oil enters support oil cylinder can realize the flexible of supporting leg, enter HM Hydraulic Motor can realize turntable about the revolution, enter amplitude oil cylinder 9 and can realize the variation of telescoping boom operating angle, enter telescopic oil cylinder of suspension arm and can realize the flexible of telescoping boom, enter the operation that hoists that lifting motor can be realized lifting mechanism.
