Abstract

The invention discloses a locating device for a chiselling machine which ensures grooves on the chiselled concrete surface to be distributed uniformly. The locating device is characterized in that a fastening bolt and a fastening nut tighten the two ends of a fastening ring via through holes; a locating platform and the fastening ring are welded together; a fixed fluted disc is fastened on the locating platform by a bolt and a nut; a connecting rod is welded on a movable fluted disc; the movable fluted disc and the fixed fluted disc are meshed and are connected as a whole by a bolt; a locating rod is installed in a sleeve; the diameter of the rear part of the locating rod is greater than that of the front part of the locating rod; the diameter of the front end outlet of the sleeve is smaller than the inner diameter; a spring is installed at the rear end of the locating rod; and the rear end of the sleeve is connected with a screw on a connecting piece as a whole by a bolt. The locating device has the following beneficial effects: when the chiselling machine works, the head of the locating rod is embedded into the groove chiselled last time, the chiselling machine is moved horizontally and the locating rod is maintained to slide in the groove all the time, thus ensuring the horizontal movement track of the whole machine to be parallel with the groove chiselled last time and ensuring the grooves on the rough surface to be distributed uniformly.

Description

A kind of positioner of dabbing machine

Technical field

The present invention relates to a kind of instrument, particularly a kind of instrument of dabbing concrete surface.

Background technology

Along with the Large scale construction of highway and railway, the construction quality of bridge and operation state concern broad masses of the people's life security.Concrete between bridge central sill body and the beam body is connected to construction quality and the operation security aspect of bridge and occupies very consequence, as do not guarantee to connect preferably, be difficult to form whole between the Liang Yuliang, the bridge actual forced status just is not inconsistent with designing and calculating, makes the bridge operation security stay hidden danger.For this reason, as the concrete box girder of a kind of structural shape of bridge, its termination and wing plate limit dabbing are particularly important.The quality of dabbing, the total quality of new and old concrete combination when directly wet joint, wet seam are built in impact.The purpose of dabbing all is can form an integral body between the old and new's cement concrete in order to make.Surface after the quilt cutter hits not only will be removed laitance and also should be formed concavo-convex pitted skin, rather than a smooth hair side, and only in this way New-old concrete could bind as a whole.Adopt now the artificial chiseling method to exist light face cutter not thorough, light face more, time-consuming; Adopt the dabbing machine, because dabbing machine termination is larger, fuselage shaking is large, be difficult to control the location, the impression orbit of digging out does not reach design standard, makes the groove of digging out inhomogeneous, and some places are wide, some places are narrow, a lot of situation low grooves occur crooked, make whole hair side upper concave groove space every having serious uneven phenomenon with distance, when causing bond between fresh and hardened concretes, adhesion is uneven, makes easily the part serious quality problems occur.

Summary of the invention

The objective of the invention is, a kind of positioner that can guarantee the equally distributed dabbing machine of concrete chisel face groove is provided.

Technical scheme of the present invention is: comprise fastener and locator, described fastener is comprised of tight loop and fastening bolt, fastening nut, is provided with through hole after two bending of tight loop, and fastening bolt and fastening nut are by two tension of through hole with tight loop; Described locator is comprised of locating platform, fixed gear plate, movable fluted disc, connector, sleeve pipe, backstay and spring, locating platform and tight loop are welded as a whole, fixed gear plate is fastened on the locating platform by bolt, nut, connecting rod is welded on the movable fluted disc, movable fluted disc meshes with fixed gear plate, and is spirally connected and is integrated; Backstay is packed in the sleeve pipe, and backstay rear portion diameter is greater than the front portion, and the front end exit diameter of sleeve pipe is less than internal diameter, and spring is contained in the backstay rear end, and the screw rod on sleeve pipe rear end and the connector is spirally connected and is integrated.

Among the present invention, movable fluted disc and fixed gear plate engagement, and be spirally connected and be integrated, backstay is packed in the sleeve pipe, and spring is contained in the backstay rear end, and the screw rod on sleeve pipe rear end and the connector is spirally connected and is integrated.Therefore, during the work of dabbing machine, sleeve pipe and backstay protract and backstay are embedded in the groove of digging out last time, translation dabbing machine during work, and keep backstay in groove, to slide all the time, thereby the translation track that guarantees complete machine is parallel with the groove of digging out last time, makes being evenly distributed of whole hair side upper groove.During down by the dabbing machine, backstay bounces back under the effect of spring, in order to keep the posture of cutter machine constant, guarantees the quality of cutter face.When adjusting the interval of groove, only need unscrew nut, on lift movable fluted disc and turn an angle, when arriving the position that needs, press down movable fluted disc and make movable fluted disc and fixed gear plate engagement, then tightening nuts gets final product.

Fig. 3 is the STRUCTURE DECOMPOSITION schematic diagram at another visual angle of Fig. 1.

The specific embodiment

Below in conjunction with drawings and Examples the present invention is described in further detail, but does not consist of any limitation of the invention.Fig. 1, Fig. 2 and shown in Figure 3 the present invention includes fastener and locator, and described fastener is comprised of tight loop 1 and fastening bolt, fastening nut, are provided with through hole after two bending of tight loop 1.During use, tight loop 1 is inserted in the fuselage of dabbing machine, again with fastening bolt and fastening nut by two tension of through hole with tight loop 1, tight loop 1 and dabbing machine fuselage are fastened as a whole.Described locator is comprised of locating platform 2, fixed gear plate 3, movable fluted disc 4, connector 5, sleeve pipe 6, backstay 7 and spring 8, locating platform 2 is welded as a whole with tight loop 1, fixed gear plate 3 is fastened on the locating platform 2 by bolt, nut, also can directly be welded on the locating platform 2.Connecting rod is welded on the movable fluted disc 4, movable fluted disc 4 and fixed gear plate 3 engagements, and be spirally connected by bolt and nut and be integrated.Backstay 7 is packed in the sleeve pipe 6, and backstay 7 rear portion diameters are greater than the front portion, and the front end exit diameter of sleeve pipe 6 is less than internal diameter, and backstay 7 is packed into behind the sleeve pipe 6, can not skid off from sleeve pipe 6 front end exit.Spring 8 is contained in backstay 7 rear ends, and sleeve pipe 6 rear ends covers has screw thread, and is spirally connected and is integrated with screw rod on the connector 5.Adjust first before the work, unscrew the nut on the connector 5, then lift movable fluted disc and revoling tube 6 to the angle that needs, guarantee that drill bit is essentially the multiple at groove interval to the distance of 7 of backstays, then put down movable fluted disc 4, make movable fluted disc 4 and fixed gear plate 3 engagements, last tightening nuts gets final product.During work, for the first time raggle need conscientiously be dug out groove as reference, during for the second time raggle, backstay 7 is stretched in the groove of digging out for the first time, and can not skid off groove, start the work of dabbing machine, guarantee that dabbing machine drill head is constant with the angle of cutter face, then, take advantage of a situation along with backstay 7 sliding traces move the dabbing machine, dig out hair side and equate with last groove interval.Back and forth carry out, make whole cutter face the groove that the interval equates substantially occur, improved the quality of whole hair side comprehensively.The machine of dabbing described in the present invention generally adopts air drill, also can adopt other brill, does not repeat them here.
