Description
The utility model relates to a kind of Special Hoisting Equipment of automobile lifting industry---tractor truck formula car hosit.
At present, the weight-lifting equipment of domestic automobile lifting industry hoisting capacity more than 50T relies on import, be the full hydraulic car hosit, add rattan NK-800 type 80T car hosit as Japan and be the full hydraulic car hosit, this horn bar adopts welded-steel plate construction, and have automatic overweight anti-locking apparatus to adapt to armed lever length variations automatic guidance hoisting crane, improved safety and operating efficiency.But have apparatus expensive, import equipment needs a large amount of foreign exchanges.
The purpose of this utility model is the mechanical type stretching structure for building industry, express highway, railway, bridge construction engineering, each big industrial and mining enterprises and stevedoring etc. provide a kind of arm, in adorn movable support bracket fastenedly, and have the large-tonnage automobile weight-lifting equipment-tractor truck formula car hosit of balance weight iron automatic installation apparatus.
The utility model tractor truck formula car hosit content Description:
The utility model tractor truck formula car hosit, it is characterized in that be by: tractor truck, car body, mechanical type hoisting arm expansion structure, arm luffing device, mechanical type Retractive leg device and support leg device, balance weight iron automatic installation apparatus constitute; Mechanical type hoisting arm expansion structure is to be provided with the hoisting arm expansion device of being made up of screw mandrel and screw in the arm on car body and the movable fixed support that is equipped with in arm constitutes; The arm luffing device is installed in the middle of the rotary disk and arm on the car body, is made up of amplitude-change speed reducer, luffing screw mandrel and screw, and under the drive of reductor in HM Hydraulic Motor, the luffing screw rotates screw mandrel ejected finishes the arm luffing; The Retractive leg device is that to be power by reductor rotating band movable wire bar rotate will be fixed on the screw advance and retreat of hanging on the leg by HM Hydraulic Motor; Leg device is to be driven by HM Hydraulic Motor screw is advanced and retreat in the screw mandrel rotation; The balance weight iron automatic installation apparatus is hydraulic actuating cylinder to be ejected under the power of Hydraulic Pump by the balance weight iron on the car body, and balance weight iron is installed on the car body automatically.
The utility model tractor truck formula car hosit is the large-tonnage weight-lifting equipment, hoisting capacity can reach more than the 80T, reasonable in design, adopt physical construction, be power with the HM Hydraulic Motor, make hoisting arm expansion, luffing with mechanical screw mandrel conduction, car body can change the state of emplacing over to by motoring condition and freely work, and it has the advantages that manufacturing process is simple, processing is simple and easy, cost is low, performance is safe and reliable, in use keeps in repair, safeguards, maintains simple and convenient, simple to operate, lifting is steady, accurate, flexible, convenient.Low cost of manufacture only is 1/3rd of an imported auto hoisting crane, and crane can 360 degree job safetys convenience.
Embodiment:
Fig. 1 is a tractor truck formula car hosit complete machine structure scheme drawing
Fig. 2 is mechanical type Retractive leg device and leg device scheme drawing
See that Fig. 1 the utility model tractor truck formula car hosit is achieved in that by tractor truck 1, tire 2, supporting leg 3, car body 4, pays volume 5, master file 6, steel cable 7, sensor 8, arm 9, amplitude-change speed reducer 10, fixed support 11, luffing screw mandrel screw 12, screw mandrel 13, screw 14, balance weight iron 15, hydraulic actuating cylinder 16, arm permanent seat 17, arm support 18, drop hanger 19 and constitute.It is characterized in that adopting 4 walkings of vehicle traction car 1 traction car body.Screw mandrel 13 is set in arm 9 the hoisting arm expansion device that is provided with on the top of car body 4 and screw 14 is formed, in arm 9, also be provided with a movable fixed support 11, fix by movable fixed support 11 again when arm 9 rotates when stretching by screw mandrel 13 and screw 14.Rotary disk and arm 9 that the arm luffing device is installed on the car body 4 are middle, form by amplitude-change speed reducer 10 and luffing screw mandrel luffing screw 12, under the drive of amplitude-change speed reducer 10 in HM Hydraulic Motor, luffing screw 12 rotates screw mandrel is ejected the purpose that reaches the arm luffing.The balance weight iron automatic installation apparatus is hydraulic actuating cylinder 16 to be ejected under the drive of Hydraulic Pump by the balance weight iron on the car body 4 15, and balance weight iron 15 is installed on the rotary disk on the car body 4 automatically.See that Fig. 2 Retractive leg device is to be power by HM Hydraulic Motor 20,21 rotations of drive reductor are rotated screw mandrel 22 will be fixed on screw 23 advance and retreat of hanging on the leg 24.Leg device is to drive reductor 26 by HM Hydraulic Motor 25 to rotate, and screw mandrel 27 is rotated screw 28 advance and retreat.
