Abstract
The utility model relates to a drawing instrument for testing concreter strength on job site. The utility model provides a detector, and a triangle supporting type base chassis is adopted to connect an oil cylinder, a manual pump and a pressure gauge into integration to avoid the defects that the existing instrument can not load uniformly and continuously and is not convenient to move, wherein, the manual pump adopts a worm gear and worm force transmission mechanism; the worm gear and worm force transmission mechanism has small driving torque, load balance and reasonable hand winding-direction. The pressure gage has an explosion-proof type digital manometer which has a peak holding function. The utility model has the advantages of high precision, reliable data, small size, light weight and convenient operation, and is not only suitable for detecting special conditions of coal mine underground but also suitable for widely using in concrete construction job site in various building industries.
Description
The utility model is a kind of on-the-spot device that detects concrete strength, can be widely used in building, the detection of industry concrete construction quality such as metallurgy, railway, especially be fit to the specific condition of coal mine operation environment, detect the compressive strength of sprayed concrete in the construction of anchor shotcreting at the scene.
Since the seventies, generally adopted the concrete strength detector made from the drawing principle design both at home and abroad.But the instrument that can be applied to the mixed native intensity of colliery downhole detection injection all the time can't be fully up to expectations.Existing questions has: because of downhole detection adopts the hydraulic system, and link to each other by very long hydralic hose between the oil cylinder of detector and the pitcher pump, the pressure loss is big, and is also inconvenient mobile; Tensimeter is common pointer-type, can't the detected instantaneous value of accurate recording; Particularly because pitcher pump is the loading of reciprocating type gap, this force mechanism makes its loading to check point discontinuous, and inhomogeneous.There are so many irrationalities, limit and influenced of the use of strong survey instrument at the colliery subsurface environment.
The purpose of this utility model be to provide a kind of both can be continuously, evenly load, be easy to move convenient and practical concrete strength drawing detector again.
Technical solution of the present utility model is as follows:
Be used to detect the drawing instrument of concrete strength, comprise the wobble pump that interconnects, oil cylinder and tensimeter is characterized in that above-mentioned each part is connected as a single entity by oil cylinder and chassis; Described wobble pump has the reciprocating worm-and-wheel gear of driven plunger.
Above-mentioned Worm and worm-wheel gearing is located at the top of the pump housing; The end of worm screw is fixedlyed connected with crank; Worm gear and the coaxial setting of piston rod, and with pump housing dead in line;
The screw rod of described piston rod for being meshed with internal thread on the worm gear center pit axially offering a groove in the outside along it, in order to by matching the rotation of restriction screw rod with banking stop that the pump housing is connected.
Described chassis be shaped as triangle, on three vertex positions, be respectively equipped with supporting-point, wherein at least two is the adjustable support point.Also be provided with the handgrip that is used for handled easily and moves on the chassis.
Described tensimeter is the explosion-proof type digital pressure gauge with peak-value-holding function.
The utility model has the advantages that conspicuous.
At first,, guaranteed that it loads evenly, steadily and continuously, driving moment is little simultaneously because hand load maintainer adopts the piston-type oil pump by the worm and gear kind of drive application of force, hand around to rationally.
Wobble pump and tensimeter are formed one-piece construction by oil cylinder and chassis, because of having shortened fluid pressure line, so have compact conformation, the oil pressure loss is little, volume is little, in light weight, and operation is light and handy, safeguards and moves all advantage easily, is more suitable for the down-hole use.And the chassis of adopting the three-point support formula, irregularity degree to the detection concrete structural surface had not both had excessive demand, and the discreteness of the data of surveying is again little, and this makes that the survey instrument has possessed the accuracy of detection height again simultaneously by force, data are reliable, measured body is destroyed little, convenient and practical outstanding feature.It not only can be used for various concrete construction sites, can also satisfy the detection demand as some coarse aggregate concretes in the building industry, and it is of wide application.
In addition, this instrument adopts mine intrinsic safety type numeral to show tensimeter, but concrete intensity level is surveyed in both direct-reading, has peak-value-holding function and explosion-proof performance again, thereby improved detection speed and precision greatly, the scene that is particularly suitable for again in the special operation environment under coal mine is surveyed by force on the spot.
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
The structure distribution synoptic diagram that Fig. 2 overlooks for the utility model;
Fig. 3 is the structural drawing of wobble pump in the utility model;
Fig. 4 is a B-B cross section view among Fig. 3.
Below in conjunction with accompanying drawing the utility model is further described.
Have a leg-of-mutton chassis 6 by this as can be seen drawing instrument among Fig. 1 and Fig. 2, drawing oil cylinder 3 is positioned at the middle part on chassis 6 and fixedlys connected with this chassis; Wobble pump 8 and tensimeter 5 are fixed on the outside of oil cylinder 3 respectively, between oil cylinder 3, wobble pump 8 and the tensimeter 5, are connected by threeway 4 and sebific duct 7 again simultaneously.Three the supporting-point I that distributing triangular in shape on chassis 6, wherein at least two is the adjustable support point, in order to adapt to the irregularity degree of institute's measuring point concrete structural surface.Use for convenience and move, on chassis 6, also be provided with handgrip 2.
The concrete structure of wobble pump 8 can illustrate by Fig. 3 and Fig. 4 in the utility model.Top at the pump housing is provided with worm-and-wheel gear.Wherein the end of worm screw 11 is fixedlyed connected with crank 12; Worm gear 9 and piston rod 10 coaxial settings, and with pump housing dead in line.Described piston rod 10 is a screw rod that is meshed with internal thread on worm gear 9 center pits, and has offered a groove 13 along its axial outside; Be fixedly installed on banking stop 14 in the pump housing by matching with groove 13 on the screw rod, can limit the rotation of screw rod, promptly this bar is only finished straight reciprocating motion vertically under the drive of worm gear 9, thereby drives piston 15 work.
In addition, the tensimeter 5 that is used for dynamometry has adopted the mine intrinsic safety type numeral of specialized designs development to show tensimeter, therefore be provided with memory and coefficient conversion function, possess that the pulling capacity peak value keeps automatically, the direct-reading intensity level, under-voltage shows and outrange demonstration and explosion-proof performance.
