Description
Technical field
The utility model relates to a kind of experiment auxiliary device, specifically jacking system.
Background technology
Under laboratory condition, Small Centrifugal Fan is through being usually used in the propulsion source of wind tunnel system, the series and parallel arrangement of multiple experimental section or multiple stage small-sized fan can be connected for realizing a centrifugal blower, often need Mobile fan equipment, and blower fan center height is adjusted, therefore, need to move a kind of jacking system of problem by the blower fan solved in laboratory conditions.
Current movable lifting platform generally provides elevating function by leading screw or hydraulic efficiency gear, and bottom it, installs wheel to facilitate movement.But, when bay-lift needs install be similar to this equipment very high to stability requirement of blower fan time, the bay-lift general satisfaction of traditional type not this generic request; In addition, such as, when lifting table work under bad environment, when ground is out-of-level, single leading screw lifting table or coordinated type multifibres thick stick lifting table cannot meet the requirement of equipment to operating water levelling.
Publication number is the patent of CN 202296985 U, screw lifting device is driven to realize elevating function by handwheel, be provided with four guide rail wheel in the both sides of car body, move for lift car on guide rail, this design both can realize the movement of equipment and lifting two functions simultaneously.But in actual use, due to lead screw linkage, overall rising and decline can only be realized, Level tune cannot be carried out to workplatform; In addition, owing to adopting Guide Rail Design, its moving range is more limited, can only move by looking for default circuit.The patent of publication number CN201240803Y, containing lifting mechanism, lifting drive assembly, vehicle frame and wheel, its principle of work and aforementioned patent basically identical.The same with aforementioned patent, the load bearing support of whole platform is born primarily of four wheels, and when lifting table works under sharp pounding environment, platform is sliding phenomenon probably.
Summary of the invention
The purpose of this utility model be to provide blower fan is provided in laboratory conditions movement, while blower fan central horizontal elevating function, meet the mobile lifting tables for centrifugal blower of higher stability and the adjustable requirement of levelness.
The purpose of this utility model is achieved in that
The utility model is used for the mobile lifting tables of centrifugal blower, it is characterized in that: comprise car body, worm wheel screw rod lifting machine, described car body comprises the top layer and bottom that are connected up and down, top layer is fixed with the bracing frame for installing centrifugal blower, a subtend face of bottom is all fixed with elevator mounting bracket, two ends before and after each elevator mounting bracket, worm wheel screw rod lifting machine is separately installed with by each self-corresponding elevator mounting blocks, two elevator mounting brackets are arranged respectively the hole that the leading screw for four worm wheel screw rod lifting machines is elevated, circular support foot pad is all established bottom the leading screw of each worm wheel screw rod lifting machine, below car body bottom, four Moving casters are installed, car body top layer installs handrail.
Advantage of the present utility model is: when the utility model platform rises, the car body comprising Moving caster will by jack-up, and castor has departed from ground, and whole platform is provided support by the jacking system with base for supporting, adds the working stability of centrifugal blower.Meanwhile, four jacking systems are distributed in the corner of platform, can work independently separately, facilitate the adjustment to plateau levels degree.Particularly, under centrifugal blower is operated in the unequal working environment in ground, require again that implement has certain level when spending, the design of corner lifting can provide larger setting range, facilitates the adjustment to plateau levels degree simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is bottom view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing citing, the utility model is described in more detail:
Composition graphs 1 ~ 2, the utility model is made up of car body 1, elevator 2, elevator mounting blocks 3.Car body 1 is formed by fixedly connecting by square aluminium, is divided into two-layer.Top layer is equipped with installs bracing frame 8, handrail 4, and bracing frame 8 and bolt hole 5 are used for installing and fixed operation equipment.Elevator mounting bracket 7 is had on the upside of bottom, elevator mounting blocks 3 is fixed on erecting frame 7 by welding manner, elevator mounting blocks 3 has bolt hole 9, position and size corresponding with the mounting hole bottom elevator 2, the mode that elevator 2 is bolted is fixed on elevator mounting blocks 3.The central authorities of elevator mounting blocks 3 have circular hole, and the elevating screw 11 for elevator 2 passes, and has circular support foot pad 10, provide support during in order to work bottom leading screw 11.Be provided with Moving caster 6 on the downside of vehicle frame bottom, castor 6 is bolted.
During use, first centrifugal blower is fixedly mounted on the erecting frame 8 of vehicle frame top layer.Moving caster 6 is housed at the bottom of car, can by platform movement to correct position by Manual-pushing handrail 4.Drive worm gear elevator 2 by handwheel, when leading screw 11 extend out to certain length downwards, platform will by jack-up, and castor 6 is unsettled, adjusts the extension elongation of four elevators 2 respectively, platform can be adjusted to proper height and suitable levelness.Height and Level-adjusting after, on platform, centrifugal blower just can normally work.After the end of job, by worm gear elevator handwheel, leading screw 11 is retracted to car body 1 inside again, car body weight is born by Moving caster 6 again, can move easily, thus realizes centrifugal blower and carry out the array modes such as series, parallel to meet different experiments demand.
Centrifugal blower movable lifting platform of the present utility model is made up of car body 1, Moving caster 6, worm gear elevator 2, elevator mounting blocks 3; Car body 1 is divided into two-layer, is formed by fixedly connecting by square aluminium, and top layer, for installing centrifugal blower equipment, is provided with and installs bracing frame 1 and fixed orifice 5; For installing screw-threaded shaft elevator 2 on the upside of bottom, jacking system is fixedly connected on mounting blocks 3, and mounting blocks 3 is fixedly connected on the mounting bracket 7 on the upside of bottom, and four Moving casters 6 are housed on the downside of bottom; Jacking system can be used to provide larger lifting travel, when extension is packed up, whole platform is by caster support 6, can random shift position, when needing to hoist, extension stretches out, by car body 1 jack-up, be provided with bottom the extension of jacking system and support foot pad 10, be used for improving working stability when platform rises; Bottom erecting frame is equipped with altogether four jacking systems, jacking system works independently separately, and lifting travel all can regulate separately, to ensure the levelness of lifting table, is particularly useful for the working environments such as ground unfairness.
This jacking system can be worm gear elevator 2, and Worm gear feed screw elevator 2 is made up of worm reduction gear and elevating screw, and its deceleration component is worm drive, utilizes worm screw to drive worm gear to realize slowing down.Worm gear center is female thread structure, is equivalent to the nut of elevating screw, and elevating screw 11 matches.During use, by handwheel or driven by motor worm screw, and then leading screw 11 is driven to be elevated.
