Description
Technical field
The utility model belongs to the autocrane technical field, is specifically related to
OnePlant Car Crane Retractable Arms assembling General hydraulic platform, can be suitable for long 10m, wide 0.9m, the Car Crane Retractable Arms assembling of high 0.7m, and can simulate arm in the flexible working condition tests of car load.
Background technology
Along with developing rapidly of economic construction, the capital construction dynamics strengthens just gradually, the construction scale of the infrastructure such as road traffic, airport, harbour, water conservancy and hydropower, urban construction is also increasing, there has been higher requirement in market to whole vehicle stability, reliability simultaneously to the increase in demand of autocrane.The arm assembling of autocrane is one of car load assembling key.At present, autocrane manufacturing enterprise does not use the mode of hydraulic drive at the arm fit on, some only relies on the assembling means of driving pulling and mechanical braking, because arm is difficult for more greatly grasping balance, when arm assembling at different levels, can not guarantee concentricity, easy scratch surfaces externally and internally during assembling, the arm assembly difficulty is large, efficient is low, and there is potential safety hazard in operation.Simultaneously, can not realize the hoisting arm expansion working condition experimenting after the arm assembling is finished, can only after finishing the car load assembling, could realize flexible working condition experimenting to arm, produce such as hoisting arm expansion and interfere, must dismantle whole arm and reprocess.
The utility model content
The utility model provides a kind of Car Crane Retractable Arms assembling General hydraulic platform for the problem that existing Car Crane Retractable Arms mounting technology exists, and can assemble easily, steadily, safely arm, reduces assembly difficulty, increases work efficiency.
The technical solution of the utility model is as follows:
A kind of Car Crane Retractable Arms assembling General hydraulic platform, it comprise fixed support, telescopic oil cylinder, two hydraulic elevating platforms, two connection dollies, two connecting rods, rail and supporting seat, Hydraulic Station.
Described supporting seat is arranged on rail rear, ground, and fixed support is arranged on rail dead ahead, ground, lies in ground.
Described hydraulic elevating platform be connected dolly be installed in ground rail on.
One end of described telescopic oil cylinder be connected the dolly I and connect, the other end be connected the connection of dolly II, the cylinder bar of telescopic oil cylinder is fixed on the connecting support seat, the fluid pressure line of telescopic oil cylinder is connected with the dynamical system Hydraulic Station.
One end of connecting rod I be connected the dolly II and connect, an end is connected with the hydraulic elevating platform I.
The two ends of connecting rod II are connected with the hydraulic elevating platform II with the hydraulic elevating platform I respectively.
This Car Crane Retractable Arms assembling General hydraulic platform is to drive telescopic oil cylinder by the dynamical system Hydraulic Station, drives two hydraulic elevating platforms and moves forward and backward along ground rail direction, reaches light, steady, the safely assembling of arm.It can be suitable for long 10m, wide 0.9m, and the Car Crane Retractable Arms assembling of high 0.7m can guarantee the concentricity when arm assembling at different levels, avoids the scratch surfaces externally and internally, reduces arm assembly difficulty and potential safety hazard, increases work efficiency.Simultaneously, an external hydraulic workstation after the assembling of whole arm is finished is realized the flexible working condition experimenting of arm, can find the quality problems that hoisting arm expansion is interfered before the car load assembling is finished, thus better solve autocrane car load dependability can problem.
Description of drawings
Fig. 1 is the structural representation of the utility model Car Crane Retractable Arms assembling hydraulic platform;
Among the figure: 1 Hydraulic Station, 2 connecting support seats, 3 connect the dolly I, 4 telescopic oil cylinders, 5 connect the dolly II, 6 connecting rod I, 7 hydraulic elevating platform I, 8 connecting rod II, 9 hydraulic elevating platform II, 10 ground rails, 11 fixed supports, 12 arms, 13 by the tying up arm.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Referring to Fig. 1, this hydraulic platform comprises three fixed supports, a telescopic oil cylinder, and two hydraulic elevating platforms, a Hydraulic Station, two connection dollies, Second Mate's connecting rod, the ground rail, a connecting support seat, wherein:
One end of telescopic oil cylinder 4 be connected dolly I 3 and connect, the other end be connected 5 connections of dolly II, telescopic oil cylinder cylinder bar is fixed on the connecting support seat 2, and the telescopic oil cylinder fluid pressure line is connected with dynamical system Hydraulic Station 1.
One end of connecting rod I 6 be connected dolly II 5 and connect, an end is connected with hydraulic elevating platform I 7.
Are connected with the hydraulic elevating platform II with hydraulic elevating platform I 7 respectively and are connected two self-powered systems of hydraulic elevating platform (manual pump+oil cylinder) in the two ends of connecting rod II 8.
Three fixed supports 11 lie in ground, and in ground rail 10 dead aheads.
The process of assembling arm is as follows:
The arm 12 that need not install lain in a horizontal plane on the fixed support 11 and fixing, will be lain in a horizontal plane on hydraulic elevating platform I 7 and the hydraulic elevating platform II 9 by tying up arm 13, about minute in after fixing.Dynamical system by hydraulic elevating platform is regulated lifting position, the concentricity of the arm that assurance need install and fixed support upper boom portion.
Drive telescopic oil cylinder 4 motions by dynamical system Hydraulic Station 1, telescopic oil cylinder 4 band be dynamically connected dolly I 3 and with being connected dolly II 5 edges rail move, and promote two hydraulic elevating platforms by connecting rod I 6 and connecting rod II 8 and move along the ground rail, the arm that need are installed is packed in the arm on the fixed support.
By changing connecting rod I 6 and the connecting rod II 8 of different length, can be applicable to the arm assembling of 8T-25T autocrane different length, efficiency of assembling is high.
Autocrane arms at different levels at the external hydraulic workstation of boom assembly afterbody, can be realized the hoisting arm expansion working condition tests after arm assembling hydraulic platform is finished assembling.
