The utility model discloses the running speed is high, the vibration reinforce, and the noise is low, and is longe -lived, and the assembly maintenance is simple, and the product can increase substantially the on -the -spot work efficiency of concrete construction, enables the concrete and gets rid of inside air fast, strengthens the wholeness of concrete and reinforcing bar, and the engineering accords with construction requirements totally.

Description

Concrete vibration bar

Technical field

This utility model relates to a kind of vibrating head, particularly relates to a kind of concrete vibration bar.

Background technology

Now domestic planet concrete vibration bar there is problems in that

One, planetary orbit is that thin-wall sleeve embeds in pipe fitting, and assembling complexity is vibrated little, easy to fall off, maintenance complexity, and maintenance inconvenience, changing planet set needs special equipment to heat, and individual cannot change；

Two, internal rotating bearing is wide arc gap plain bearing, and rotating speed is low, easily generates heat, and frictional force is big, and noise is big, and the life-span is short；

Three, articulation position is single oil sealing, and sealing is poor, and oil loses rubbish and is easily accessible bearing entrance planet set, causes bearing damage, without shaking the faults such as power.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of concrete vibration bar, its running speed is high, vibration force is strong, noise is low, and the life-span is long, assembles easy to maintenance, product can increase substantially the work efficiency of concrete construction site, concrete being made quickly to get rid of inner air, add the globality of reinforced concrete and reinforcing bar, engineering complies fully with construction requirement.

This utility model solves above-mentioned technical problem by following technical proposals: a kind of concrete vibration bar, it includes overall planetary, barred body, planet axis, seal nipple, packing ring, oil sealing, groove, plush copper, fixture, swivel bearing, barred body and planetary are threaded, planet axis is fixed on the inside of barred body, seal nipple is positioned at the front end of swivel bearing, packing ring is positioned at swivel bearing both sides, oil sealing is positioned at the rear and front end of swivel bearing, groove is positioned at the side of plush copper, fixture is installed on the front end of barred body, and swivel bearing installs the front end with planet axis.

Preferably, described planet axis material is 42CrMo high strength alloy steel.

Preferably, described swivel bearing is the professional high speed self-aligning ball bearing of double nylon bracket.

Preferably, the structure of described oil sealing is double oil seal structure.

Positive progressive effect of the present utility model is in that: this utility model running speed is high, vibration force is strong, noise is low, life-span is long, assembling easy to maintenance, product can increase substantially the work efficiency of concrete construction site, and concrete can be made quickly to get rid of inner air, adding the globality of reinforced concrete and reinforcing bar, engineering complies fully with construction requirement.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model concrete vibration bar.

Detailed description of the invention

This utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.

As shown in Figure 1, this utility model concrete vibration bar includes overall planetary 1, barred body 2, planet axis 3, seal nipple 4, packing ring 5, oil sealing 6, groove 7, plush copper 8, fixture 9, swivel bearing 10, barred body 2 is fixed on the inwall of overall planetary 1, planet axis 3 is fixed on the inside of barred body 2, seal nipple 4 is positioned at the front end of swivel bearing 10, packing ring 5 is positioned at swivel bearing 10 both sides, oil sealing 6 is positioned at the rear and front end of swivel bearing 10, groove 7 is positioned at the side of plush copper 8, fixture 9 is installed on the front end of barred body 2, and swivel bearing 10 installs the front end with planet axis 3.

Overall planetary constitutes a complete planet nested structure with planet axis, not only vibration force is big, do not fall off, maintenance assembling simple and fast (within 1 minute) and firmness outside are consistent with inner hardness, shock resistance, wear-resistant, the function that simultaneously can reach to run up (domestic is typically in 2800 revs/min, and this structure rotating speed can reach 12000 revs/min) namely become vibration at high speed rod with high-speed electric expreess locomotive combination, vibration efficiency can be greatly improved；Swivel bearing can reach 26000 revs/min the most at a high speed, is greatly improved the speed of rotation, and noise is little, and the life-span is long；The sealing of oil sealing is high, can effectively stop greasy dirt to enter the structure such as bearing, planetary orbit, reduce fault, life-saving.

Particular embodiments described above; to of the present utility model solving the technical problem that, technical scheme and beneficial effect further described; it is it should be understood that; the foregoing is only specific embodiment of the utility model; it is not limited to this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
