Description
Technical field
The utility model relates to the equipment that vibrates after a kind of concrete casting, especially a kind of vibrating head.
Background technology
At present, Chang Yong concrete vibration bar involving vibrations head, wired hose, power transmission flexible cord, motor are formed.The power of vibration head is produced by motor, passes to vibration head by the power transmission flexible cord and produces vibration.
But because the length of transmission flexible cord is fixed, the radius of clean-up of vibration head is limited, and therefore need often to adjust the position of vibrating head and motor, and because motor weight is big, therefore operation is very inconvenient.
The utility model content
In order to overcome the deficiency of existing vibrating head, technical problem to be solved in the utility model provides a kind of lightweight concrete vibration bar.
The technical scheme that its technical problem that solves the utility model adopts is: concrete vibration bar, involving vibrations head and shell thereof, wired hose, lead, power supply, be provided with drive coil, resetting structure, crash feature in the described shell, drive coil is connected with power supply after change-over switch by lead, crash feature is controlled drive coil by change-over switch, and at drive coil and resetting structure effect lower edge vibration head axially reciprocating, crash feature in reciprocating motion at least with cover attack once.
The beneficial effects of the utility model are: thus produce vibration by the axially reciprocating of crash feature and with cover attack, avoided the use of motor, whole installation weight is light, and is therefore easy to operate, and volume is little, low cost of manufacture.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the partial enlarged drawing of the utility model change-over switch.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 and Figure 2, concrete vibration bar of the present utility model, involving vibrations head 1 and shell 11 thereof, wired hose 6, lead 5, power supply, be provided with drive coil 2, resetting structure, crash feature in the described shell 11, drive coil 2 is connected with power supply after change-over switch 4 by lead 5, crash feature is by change-over switch 4 control drive coils 2, and at drive coil 2 and resetting structure effect lower edge vibration head 1 axially reciprocating, crash feature is collided once with shell 11 in reciprocating motion at least.
Thereby produce vibration by the axially reciprocating of crash feature and with shell 11 collisions, avoided the use of motor, whole installation weight is light, and is therefore easy to operate, and volume is little, low cost of manufacture.
In order to increase the reliability of device, described resetting structure is arranged on the back-moving spring between shell 11 and the crash feature, crash feature disconnects or conducting drive coil 2 and power supply by change-over switch 4, and back-moving spring elastic force direction is opposite with drive coil 2 magnetic force direction.
In reciprocating whole process, back-moving spring can both apply the effect of power to crash feature, when therefore initial, crash feature gets drive coil 2 by control change-over switch 4 under the effect of back-moving spring, crash feature is subjected to the magneticaction axial-movement, while back-moving spring storage elasticity potential energy, crash feature makes drive coil 2 dead electricity by control change-over switch 4 after leaving initial position, magnetic force disappears, crash feature resets under action of reset spring, and it is electric by change-over switch 4 drive coil 2 to be got once more when colliding with shell 11, moves back and forth thereby produce axial circulation.
Equally, resetting structure also can be drive coil 2 itself or the another set of magnetic direction resetting coil opposite with the magnetic direction of drive coil 2 that increase, crash feature makes drive coil 2 or resetting coil produce an opposing magnetic field by control change-over switch 4, thereby crash feature is resetted under the effect of reverse magnetic force, and then produce iterative motion.
But no matter be by drive coil itself or increase the opposite magnetic field of resetting coil generation crash feature is resetted, the capital increases the complexity of change-over switch 4 circuit, as increase the self holding circuit in magnetic field etc., because thereby the vibrating head work under bad environment may reduce the reliability of device, and with respect to back-moving spring optional position, any time all to the collision structure function, reset magnetic field requires more strict to trigger position, may cause failure of apparatus when the crash feature amplitude is too small.
In order to limit the motion of crash feature, be provided with guide frame between between described crash feature and the shell 11.
Play the effect of obstruction for fear of back-moving spring when colliding, described action of reset spring direction is consistent with collision course, be that crash feature exists, certainly crash feature also can bump under drive coil 2 effects, perhaps round trip all bumps, but under the situation that does not have the magnetic field self holding circuit, crash feature can only overcome back-moving spring by its inertia, thereby causes its vibrating effect not obvious.
In order to increase the durability of device, described change-over switch 4 comprises movable contact 47 and the fixed contact 48 that is fixed on the shell, and described crash feature is by the Position Control change-over switch 4 of control movable contact 47.Compare with contact switch, travel switch etc., the change-over switch maintenance that fixed contact 48 and movable contact 47 are formed is more convenient, durability is higher, use cost is lower.
Described movable contact 47 can directly be fixed on the crash feature and its servo-actuated, but between fixed contact 48 and movable contact 47, bump firmly, described fixed contact 48 is fixing by the support 41 that is fixed on the shell 11, support 41 is provided with the slide bar 42 that is slidingly matched with it, described movable contact 47 is fixed on the slide bar 42, be provided with the disconnection spring 43 opposite between support 41 and the slide bar 42, described slide bar 42 and crash feature interlock with back-moving spring elastic force direction.
Crash feature under action of reset spring by movable contact 47 is contacted with fixed contact 48 with the slide bar 42 of its interlock, thereby drive coil 2 is got, after crash feature moves upward under magneticaction, slide bar 42 makes movable contact 47 and fixed contact 48 keep often opening under 43 effects of disconnection spring, thereby make drive coil 2 dead electricity, crash feature continues motion and resets after one section under effect of inertia, produce iterative motion then.
Because slide bar 42 and crash feature interlock cause slide bar 42 and support 41 to bump firmly for fear of crash feature overshoot in the magneticaction stroke, are provided with the buffer spring 49 identical with back-moving spring elastic force direction between described support 41 and the slide bar 42.
