Abstract
The utility model discloses a carbon fiber bonding strength detector which is used for detecting the strength of concrete structure which is strengthened or repaired by carbon fiber plates. A pump body of a hand pump is axially connected with a cylinder body of a load cylinder which is communicated with the hand pump through an oil pipe. The utility model has comfortable and convenient operation, continuous and stable manual loading, reliable sealing of hidden oil pipe and accurate detection and can automatically record max bonding strength value, thereby being suitable for the detection of strengthening and repairing concrete structure in mine, tunnel, building and water reservoir.
Description
Technical field
The utility model relates to a kind of carbon fiber binding strength detecting instrument.
Background technology
When the xoncrete structure building needed reinforcement or repairs, the Carbon Fiber Sheet-Reinforced that can bond on concrete will or be repaired the position and carry out surface treatment, priming operation resin, levelling and stickup carbon fiber plate etc. usually concrete structure reinforcement.The character and the consolidation effect of the construction quality of each operation and adhesive material itself are closely related, therefore binding material and concrete cohesive strength are the important overall targets that the rehabilitating concrete architecture quality is reinforced in reflection, still there is not at present suitable detecting instrument, the temporary multi-tester replaces, and therefore can not accurately reflect actual bond strength.
Summary of the invention
The purpose of this utility model provide a kind of be used for detecting by carbon fiber sheet reinforce or rehabilitating concrete structure and the carbon fiber binding strength detecting instrument of forming by oil pump, load cylinder, back-moving spring, pressure transducer, digital pressure gauge, coupling shaft, nut and calibrated bolck that designs.
The purpose of this utility model is achieved through the following technical solutions, a kind of carbon fiber binding strength detecting instrument, comprise calibrated bolck, nut, oil pump, pressure transducer and digital pressure gauge, it is characterized in that: the pump housing and load cylinder cylinder body are for axially to be connected, and oil pump is communicated with load cylinder through oil circuit.
The coupling shaft that is fixed on the load cylinder piston is connected for floating with nut.Oil circuit between load cylinder and the oil pump is for the built-in oil circuit by pump body, load cylinder cylinder body or be located at the pipeline of detector outside.
The utlity model has following beneficial effect:
1. the utility model utilizes hydraulic loaded, and handgrip obtains bigger reduction gear ratio by worm and gear, shakes handgrip and makes the load cylinder pressurization through worm and gear, screw-and-nut mechanism, operate comfortable easily, load stable, continuous.
2. structure of the present utility model is a right cylinder, and during use, one holds detector, and another hand rotates handgrip and loads, and execute-in-place is very convenient.Can face upward, crouch, stand multiple posture operation.
3. the employing of the oil circuit between load cylinder and the wobble pump is built-in, has cancelled external oil pipe and joint, and sealing is reliable, keeps in repair, assembles also very convenient.
Between calibrated bolck and the coupling shaft for sphere, the unsteady of taper hole combination are connected, can compensate the non-perpendicularity error between measured surface and body, detected value is accurate.
5. the control of carbon fiber binding strength detecting instrument shows by the intelligent digital pressure gauge of Single-chip Controlling, pressure transducer realization.Can note the maximum bonded intensity level.
Description of drawings:
Fig. 1 is the utility model synoptic diagram (analysing and observe).
Embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Carbon fiber binding strength detecting instrument (Fig. 1) is made up of calibrated bolck 1, nut 2, coupling shaft 3, piston 4, pressure transducer 5, back-moving spring 6, wobble pump piston 7, worm and gear 8, screw rod 9, handgrip 10, the wobble pump pump housing 11 and cylinder body 12.The oil pump of present embodiment uses wobble pump, and it is wobble pump in 99208912.3 application cases that this wobble pump partly adopts application number, and it is made up of handgrip, worm and gear, piston, screw rod and the pump housing.Worm wheel aperture is an internal thread, and piston and screw rod are made as one, and the threaded hole of screw rod and worm gear matches; Rotate handgrip, piston gets final product to-and-fro movement.The wobble pump pump housing is fixedlyed connected vertically with the cylinder body of load cylinder, is provided with O-ring seal therebetween.Be provided with spring base in hand pump housing lower end, spring is loaded between piston 4 and the spring base.The piston of load cylinder cooperates the formation load cylinder with cylinder bore.Be communicated with (figure does not draw) by the built-in oil circuit of being located in the wobble pump pump housing and the housing wall between wobble pump and load cylinder.The piston 4 of load cylinder is fixing with coupling shaft 3, and coupling shaft is a multidiameter, and the inner face of the major diameter axle of coupling shaft is made as sphere, and matches with the sphere on nut top, and forming floats connects, and the nut bottom is provided with the threaded hole that the screw rod with calibrated bolck matches.The housing middle part is provided with the pressure transducer that is communicated with load cylinder.During use, need to process joint-cutting in advance earlier on the concrete walls surface, the degree of depth of joint-cutting should be cut to concrete from reinforced surface, cuts the concrete degree of depth and is generally 2-4mm, stitches wide 2mm.The bottom of calibrated bolck is the cylindrical of 40mm diameter, and material adopts 45
#Steel.Calibrated bolck and carbon fiber to be measured through gluing jail, then with the coupling shaft of this detector by being threaded firmly.At this moment can detect, one holds tester, and another hand rotates handgrip, and the pressure oil in the wobble pump enters load cylinder through built-in oil circuit the sticking carbon fiber of mending is applied pulling force.Pressure transducer is converted to the voltage signal variation with the pressure variation of detector hydraulic system, this signal is through voltage amplification, the voltage-frequency conversion, voltage instrument signal is become the counting channel that frequency signal is sent into the single-chip microcomputer of digital pressure gauge (AT89C2051), the every 50ms of single-chip microcomputer interrupts once carrying out data processing, every 0.25s upgrades once and shows just have the demonstration of following, peak value maintenance, data storage, data presentation by button operation, functions such as zero clearing, removing storage data.When the carbon fiber sheet of bonding by when concrete is left behind, single-chip microcomputer is noted intensity level at this moment automatically.Digital pressure gauge and pressure transducer are the product that known technology is made, and all there is sale in market, can choose on market.
