Technical field
The utility model relates to the metering professional domain, adopt the frame-type calibration method, a kind of complete standard device during calibrating/calibration (hereinafter referred to as calibrating) hydraulic jack, especially because of its some structure mobility, rotatability design and employing New type weight loading material, so that it is free and relaxed to carry out calibration operation in laboratory and working-yard, also improve simultaneously the calibrating accuracy, reduced the wearing and tearing of workplace, the serviceable life of having improved reaction frame.Filled up the present domestic blank of examining and determine the lifting jack set of equipments specially of not having.The resistance to compression that reaction frame partly also can be used for separately the various materials such as huge concrete structure, large-scale workpiece on the engineering detects; Also can expand to universal testing machine, so that range of application is wider.
Background technology
At present, by described in the national verification rules JJG621-2005 (hydraulic jack vertification regulation)---when adopting the frame-type calibration method of one of calibration method, the narrating content many places are not enough.Such as, one, (the rules content for lifting jack being placed in the middle of the calibrating frame base, is connected in series with the strain-type standard dynamometer in detail in the time of will " lifting jack, strain-type standard dynamometer and calibrating framework (hereinafter referred to as reaction frame) centering ".Make lifting jack, strain-type standard dynamometer and calibrating framework centering), present equipment and the method that does not have on the market automatic centering; Large-scale lifting jack is lifted to can be quite painstaking on the base, sometimes wants four, five people to lift, and moves during centering also can bother and the calibrating face of wearing and tearing.It two is " between lifting jack and strain-type standard dynamometers; can place as required cushion block; adjust spatial altitude; make the jack piston overhang near duty ", and this cushion block is heavy and bother with carrying, sometimes, the space is too high, the meeting pad is a plurality of, and also trouble is looked at the scene, neither a good way.Its three, reaction frame in the market is generally very heavy, have up in addition reach more than the 10T, transport to the heavy trouble in working-yard.
Summary of the invention
Do not have movable part in order to overcome existing lifting jack calibration operation platform, its headroom can not freely be adjusted; Lifting jack, strain-type standard dynamometer and calibrating framework (being reaction frame) centering difficulty; Reaction frame is unusually heavy and do not have at present these deficiencies of the complete calibrating installation of special lifting jack to design these devices.
The technical scheme that its technical matters that solves the utility model adopts is: packaged type lifting jack calibrating installation, it comprises that the lifting shelf of reaction frame column, base plate, rotary table, strain-type standard force-measuring flowmeter sensor part, this sensor and oil cylinder, top board, strain-type standard force-measuring meter show that reading device, manual pump are linked in sequence, it is characterized in that: reaction frame consists of framework by column, base plate, top board, rotary table is installed on the pillar of base plate, and it has slide rail to lead the way; Strain-type proof force flowmeter sensor is put on the cylinder bracket of hydraulic pressure lift, and oil cylinder places top board, and passes through top board.Be placed with strain-type normal pressure meter reading display above the top board, the pump of lift cylinder also is put in one jiao on top board.
The lifting of top board is finished by being placed in manual pump on the top board, one-way throttle valve etc.; Distance between top board and base plate is divided into 400mm, 800mm, 1200mm third gear, according to the position of the Height Adjustable top board of lifting jack, sets up the lifting jack calibrating installation and detects height, also just embodies portable feature.
On reaction frame base plate one column rotatable index(ing) table is housed, when the handwheel that rotates counterclockwise on the transposition worktable, worktable is lifted from base plate, be rotated further, index(ing) table can produce between two columns; Worktable produces outside the column, and tested lifting jack is put worktable face of cylinder center, rotary work-table, allow tested lifting jack go to line of corner post on, namely with base side angle at 45 °; Clockwise rotate handwheel, index(ing) table and lifting jack are pushed into the base plate center, begin after making worktable and base plate sturdy to detect.
The Sensor section of strain-type standard force-measuring meter is installed on the anchor clamps of the lift cylinder on the top board, the digital display part
Be put in the support of top board top.
The device that adopts the hand-hydraulic cylinder freely to promote is realized the free height adjustment of calibration operation platform.Adopt universal stage and slide rail, solve the centering problem.Adopt auxiliary fork truck, large-scale lifting jack is unloaded up and down in solution and whole device is moved problem.Adopt the high strength forgings material, load-bearing capacity is large, and is lightweight, and whole device is less than 1.5T, is 1/9th weight of framework on the market.The below specifically narrates on physical construction: this device is combined by framework (being reaction frame) and strain-type standard force-measuring meter and auxiliary handling machinery fork truck.Strain-type standard force-measuring meter is installed on the framework (being reaction frame).Reaction frame then is to be connected to form by sequential machines such as the shelf of four pillars, base plate, rotatable index(ing) table, manual pump, lift cylinder and installation dynamometer sensor shelf, top board and installation dynamometer, dynamometer displays.Wherein, rotatable index(ing) table is installed on base plate one root post, and manual pump is installed on the base plate.Top board can move freely, to adjust calibration operation platform clear height.Be installed on the rotary table (claiming index(ing) table herein) of bottom, can realize the automatically light centering of lifting jack and calibration operation platform.The utility appliance fork truck is used for loading and unloading lifting jack and the whole calibrating installation of handling.Make and obtain the working-yard and examine and determine/calibrate lifting jack becoming a nothing the matter.The strain-type standard dynamometer can be changed arbitrarily the needs that Sensor section satisfies calibrating according to the range of calibrating lifting jack.In addition, reaction frame can be used for separately the resistance to compression detection of the various materials such as huge concrete structure, large-scale workpiece on the engineering; Also can expand to universal testing machine.
The beneficial effects of the utility model are, because of its some structure mobility, rotatability design and employing New type weight loading material, so that it is free and relaxed to carry out calibration operation in laboratory and working-yard, also improved simultaneously the calibrating accuracy, reduce the wearing and tearing of workplace, the serviceable life of having improved reaction frame.Filled up the present domestic blank of examining and determine the lifting jack set of equipments specially of not having.The resistance to compression that reaction frame partly also can be used for separately the various materials such as huge concrete structure, large-scale workpiece on the engineering detects; Also can expand to universal testing machine, so that range of application is wider.It is improvement and innovation to JJG621-2005 lifting jack vertification regulation calibrating installation, is a technology leap of standard and improving and renewal the rules content.
