Abstract

The utility model discloses a new bar tip for a vibrator. The bar tip (1) has a structure of connecting a foreside polygonal prism with a backside cylinder, wherein the terminal of the bar tip (1) is a screw thread connecting axis (8) with a slightly smaller diameter and the bar tip (1) can be matched with a bar tube (3). The polygonal prism of the bar tip (1) can use various structure configurations such as three edge angles (L), four edge angles (L), five edge angles (L) or six edge angles (L). The end surface of the screw thread connecting axis (Z) is provided with an axial blind hole (M) which can contain the front end of a vibration axis (2) in the bar tube (3). The bar tip (1) with the polygonal prism can enlarge a contacting area with concrete to increase friction so as to prevent the phenomena of slipping, locking and turning, and has strong vibration intensity, good vibration effect and improved work efficiency.

Description

A kind of vibrator is sharp with novel rod

Technical field

The utility model relates to the truck mixer tool, relates in particular to vibrator.

Background technology

The concrete vibrating apparatus that present domestic construction industry is adopted is generally made up by vibrating head, flexible axle pipe, union, and being connected with motor provides power.The excellent point of rod pipe front-end configuration mostly is socket cap form of structure, and the flexible axle in the flexible axle pipe rotates under driven by motor, drives rod pipe and the position hunt of excellent tip, and concrete is made firm by ramming.Because socket cap rod point is relatively slicker and more sly, when vibrating the frictional vibration effect little, locking phenomenon takes place easily, vibrating head is spinned, do not have the effect of vibrating of expectation.

Summary of the invention

The purpose of this utility model just provides a kind of excellent sharp structure of novel vibrator, increases and concrete contact area, strengthens frictional force, prevents the sharp locking of vibrating head rod, the excellent pipe phenomenon of spinning, and improves the power of vibrating and the operating efficiency of vibrator.

Task of the present utility model is finished like this: it is sharp with novel rod to design a kind of vibrator, with the supporting application of vibrating head, the rod point adopts anterior polygonal rib body to connect the rear portion cylindrical structure, and its tail end is the thin slightly axle that is threaded of diameter, can be equipped with the rod pipe of vibrating head.The polygonal rib body of rod point can adopt three corner angle or four corner angle, five corner angle, six various form of structure such as corner angle.The end face of axle of being threaded has axial blind hole, can hold the front end of rod pipe internal vibration axle.The rod point adopts the steel blank, makes through machining, heat treatment, plating zinc on surface.Rod pipe front end inner hole thread and the utility model rear end are threaded and spool cooperate suit to fix, the rod pipe is by excellent union tube connector joint, be connected with the flexible axle pipe again, the flexible axle of flexible axle tube hub stretches into the rod pipe, be sleeved in the shaft coupling, rod pipe internal vibration shaft extension goes out the outer spindle nose end connecting axle joint of bearing, is connected as a single entity with flexible axle, and the flexible axle rear end connects motor output shaft.During actual the use, start motor, the driven by motor flexible axle rotates in the flexible axle pipe, drives anterior vibrating shaft and rotates in the rod pipe, transfers vibrations to the rod point.Flexible axle drives the vibrating shaft rotation and makes the vibrating head runout, and the hand-holding rod pipe inserts position, excellent tip in the concrete and can vibrate.

Design and produce, test according to above-mentioned, proof the utility model is rational in infrastructure, matching performance is good, increased excellent point and concrete contact area, frictional force strengthens, and has prevented that excellent sharp locking and excellent pipe from spinning, vibration intensity is big, it is effective to vibrate, and has improved operating efficiency, has reached predetermined purpose preferably.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the K of Fig. 1 is to view;

Fig. 3 is the utility model and rod pipe (3) syndeton schematic diagram.

Among the figure, 1-rod point, 2-vibrating shaft, 3-rod pipe, 4-oil sealing, 5-bearing, 6-shaft coupling, 7-union, 8-flexible axle, 9-flexible axle pipe; K-line of vision symbol, M-blind hole, L-corner angle, the Z-axle that is threaded.

The specific embodiment

Below in conjunction with accompanying drawing concrete enforcement of the utility model is described further.

Consult Fig. 1, rod point 1 can adopt triangular prism or four jiaos, five jiaos, hexagonal rib body etc.With four jiaos of rib bodies is example, and it is flat that caput 1 front end is that round-sharp head is cut, and axially evenly has four road deep trouths at the cylinder-shaped body position, protrudes four corner angle L, constitutes four jiaos of rib bodies.Rear portion cylinder tail end has a thinner Z that is threaded, and has axial centre blind hole M.Select for use 45# steel cast blank to carry out machining, high frequency heat processing, hardness reaches HRC55～60, passes through sandblast, plating zinc on surface again, and is antirust wear-resisting.Consult Fig. 2, the crosscut section shape of four jiaos of rib body rod points 1 is four the uniform formation cruciate flower of corner angle L shapes.(if adopt the structure of triangular prism or five jiaos, hexagonal rib body, the crosscut section should be evenly distribute three corner angle L or five, six corner angle L mutually on periphery.) consult Fig. 3, sharp 1 tail end of a rod Z that is threaded is sleeved in the front end inner bolt hole of rod pipe 3, the front end spindle nose of the vibrating shaft 2 in the rod pipe 3 stretches in the blind hole M of sharp 1 tail end of rod, rod pipe 3 rear ends are connected with flexible axle pipe 9 by union 7, and the front end of flexible axle 8 connects the back spindle nose of vibrating shaft 2 by shaft coupling 6.The rear end of flexible axle pipe 9 is connected with motor, and motor output shaft drives flexible axle 8 rotations, and drive vibrating shaft 2 again and rotate and make rod pipe 3 and sharp 1 runout of rod, thereby to the concrete operation of vibrating.

The utility model increased excellent sharp 1 with concrete contact area, frictional force strengthens, vibrated concrete is more closely knit, high efficiency, it is effective to vibrate.
