Abstract
The utility model discloses a mortar strength investigating instrument, which mainly comprises a pair of load heads with corresponding upper and lower centers, wherein, the upper load head is fixed on the lower end of a drive bolt; the drive bolt is supported on a supporting arm; the lower load head is arranged in a cup body with a pressure sensor and is connected with the sensor; the cup body is positioned on a base; the upper end of the lower load head is provided with a fixed ball; the lower end of the upper load head is provided with a rotary ball for counteracting a rotating pivoting force of the bolt. The investigating instrument has the advantages of simple structure, small size, high precision, convenient operation, convenient carrying, low cost and easy popularization; the utility model can be used in labs and engineering sites; the supporting arm can slide, the lower load head, the cup body with the pressure sensor and the sensor can be respectively taken out, and therefore, the utility model is convenient to maintain, repair and install.
Description
(1) technical field: the utility model relates to a kind of pick-up unit, relates in particular to a kind of mortar strength detector that mortar masonry intensity is detected.
(2) background technology: in the construction work building course, brick masonry structure will be the version that has a large capacity and a wide range in some areas with in the national long term from now on, and mortar masonry intensity is an important indicator of construction quality, the height of this index directly has influence on the life-span of whole engineering, thereby perform and can find and correct qualitative problems of construction in advance to the detection of mortar masonry intensity, avoid just finding defective behind the high worker of engineering and cause irremediable loss; Detect the little tonnage pressure testing machine of the general employing of mortar masonry intensity equipment at present, this machine precision is lower, structure is huger, portably uses inconvenience.
(3) summary of the invention: in order to solve the problem that easily and fast, accurately detects mortar masonry intensity in the construction work, the utility model provides a kind of structure more simple mortar strength detector.
The technical solution of the utility model realizes in the following manner: a kind of mortar strength detector: it mainly comprises the corresponding load head in a pair of upper and lower center, wherein going up the load head is fixed on one and can descends mobile drive screw lower end, drive screw is supported on the sway brace, following load head is arranged in the cup that has pressure transducer and with sensor and is connected, cup is positioned on the base, following load head upper end is provided with a fixing ball, and last load head lower end is provided with a rotation ball in order to counteracting screw rod rotation torsion.
The sway brace lower end is positioned at the track on the base, and track is provided with fixed screw and is used for fixing the sway brace position.
Track is a slide rail, slides in slide rail in the sway brace lower end.
A side is provided with panel in order to adjust the elasticity of slide rail in the slide rail.
The drive screw upper end is fixed one and is rotated handwheel, is fixed with joystick on the handwheel.
Cup be provided with one with the dust cap of cup spiral snapping, be provided with in the middle of the dust cap and place the spacing open-work of load head down.
Following load head lower end is provided with a Connection Block that coincide with pressure transducer.
Good effect of the present utility model is: simple in structure, volume is little, the precision height, and use, easy to carry, laboratory and engineering site all can use; Cost is low, is easy to promote; Because of sway brace can slide, following load head, the cup that has pressure transducer and sensor can take out respectively, maintenance, maintenance, easy for installation.
(4) description of drawings:
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is the left TV structure synoptic diagram of Fig. 1.
(5) embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 figure, Fig. 2 as can be seen, the utility model mainly comprises the corresponding load head in upper and lower a pair of center (5,10), load head 5 is fixed on one by be connected, rotate with turning handle drive screw 3 lower ends that move up and down with the rotation handwheel on it, drive screw is supported on the sway brace 4 by the leading screw on top, drive screw 3 upper ends are fixed one and are rotated handwheel 2, are fixed with joystick 1 on the handwheel 2; Following load head 10 is arranged in the cup 8 that has pressure transducer and with sensor and is connected, and cup is positioned at the cup groove of base 7, and following load head upper end is provided with a fixing ball, and last load head 5 lower ends are provided with a rotation ball in order to counteracting screw rod rotation torsion; Sway brace 4 lower ends are positioned at the track 6 on the base 7, and track 6 is provided with fixed screw 12 fixed support arms 4 positions; As seen from Figure 2, track 6 is slide rails, slides in slide rail in sway brace 4 lower ends; A side is provided with panel 11 to adjust the elasticity of slide rail in the slide rail; Cup 8 be provided with one with the dust cap 9 of cup spiral snapping, are provided with in the middle of the dust cap 9 and place the spacing open-works of load head 10 down; Following load head 10 lower ends are provided with a Connection Block that coincide with pressure transducer.
During detection, mortar specimen is lain in a horizontal plane in down on the load head 10, make load head 5 and following load head 10 aim at the application point of on test specimen, finishing in advance, rotating rocker 1 drives handwheel 2 and rotates, and drive screw 3 rotations is moved down compress test specimen gently, slow then uniform rotation rocking bar load application, 10 on following load head can the squeeze pressure sensor, its sensor signal reaches on the signal processing apparatus in real time, and when test specimen was destroyed, its maximum pressure value also just obtained.
If wanting to take out sensor proofreaies and correct or clears up, only need screw 12 is loosened, then sway brace 4 is slided backward a distance by slide rail, just dust cap 9, following load head 10 and cup 8 and interior sensor thereof can be taken out respectively, replace again after handling, again sway brace 4 be moved on to original position, screw is screwed, just can reuse, both simple, again fast, accurately.
