Problems solved by technology

[0003] The traditional concrete vibrator includes an external motor, a flexible shaft and a vibrating rod; the vibrating rod has an eccentric rotating mechanism inside, and the eccentric rotating mechanism is driven by an external motor through a flexible shaft; its disadvantages are: first, the noise of the external motor is large, Seriously affect the surrounding environment and the physical and mental health of construction workers; 2. The cost of the flexible shaft is high, and in the working condition where the working position is complicated and the flexible shaft is bent, the transmission efficiency is low, the transmission loss is large, and the energy waste is serious; 3. , The vibrating rod is output in the mode of circumferential small-area vibration, the action surface is small, and the vibration speed of the larger-area concrete is slow

Embodiment 1

[0014] exist figure 1 In the first shown embodiment, the electromagnetic insert type concrete vibrator includes a horseshoe-shaped iron core 1, and an excitation coil 2 wound on the horseshoe-shaped iron core 1; the two magnetic poles of the horseshoe-shaped iron core 1 respectively A silicon steel sheet 3, 3' is extended downward, and the two silicon steel sheets 3, 3' are parallel to each other; the exciting coil 2 is electrically connected to an alternating power supply (not shown).

[0015] For the above-mentioned concrete vibrator, the AC power supply provides sinusoidal alternating current of 100 Hz to 200 Hz, and its frequency is basically the same as that of a traditional vibrator of 5000 r / min to 10000 r / min.

[0016] When the electromagnetic insert type concrete vibrator is working, the two silicon steel sheets 3, 3' are inserted into the concrete; since an alternating current is applied to the horseshoe-shaped iron core 1, the magnetic pole direction of the horsesho...

Embodiment 2

[0018] figure 2 Shown is the second embodiment of the electromagnetic insert type concrete vibrator, which differs from the first embodiment in that: the silicon steel sheets 3, 3' are evenly distributed with through holes 30 on the surface; During the vibration process of the silicon steel sheet 3, 3', the concrete near the surface of the silicon steel sheet can flow on both sides of the silicon steel sheet through the through hole 30 when being squeezed by the silicon steel sheet, thereby avoiding the deformation of the silicon steel sheet. After the silicon steel sheet is pulled out, the concrete leaves a sheet socket.

Embodiment 3

[0020] image 3 The bottom view of the silicon steel sheet 3, 3' in the shown embodiment three of the vibrator is different from the silicon steel sheet in the first embodiment in that the silicon steel sheets 3, 3' in the third embodiment are folded at right angles plate, and the two silicon steel sheets 3, 3' are symmetrical with respect to the symmetry plane P of the horseshoe-shaped iron core, and the two silicon steel sheets open angle outward and face away from each other.

[0021] According to the scheme of embodiment three, when the two silicon steel sheets 3, 3' are attracted to each other and approach each other, the outer surface of the opening angle of the silicon steel sheet just pushes outward the concrete in the direction perpendicular to the displacement direction of the silicon steel sheet; during this process , the moving direction of the silicon steel sheet and its pushing direction to the concrete are as follows: image 3 Indicated by the solid arrow.

Abstract

The invention provides an electromagnetic inserting piece type concrete vibrator which comprises a horseshoe-shaped iron core and an excitation coil wound on the horseshoe-shaped iron core. The two magnetic poles of the horseshoe-shaped iron core both extend downwards to form two silicon steel pieces, and the excitation coil is electrically connected with an alternating-current power supply. The vibrator is free of work noise, low in cost, small in energy consumption, large in vibration action face and high in work efficiency.

Description

technical field [0001] The invention relates to the field of building construction equipment, in particular to a concrete vibrator. Background technique [0002] In the field of building construction, in order to make the texture of the cast-in-place concrete uniform and remove the air bubbles in the concrete, it is necessary to vibrate the concrete after the pouring is completed; the basic equipment used in this process is a concrete vibrator. [0003] The traditional concrete vibrator includes an external motor, a flexible shaft and a vibrating rod; the vibrating rod has an eccentric rotating mechanism inside, and the eccentric rotating mechanism is driven by an external motor through a flexible shaft; its disadvantages are: first, the external motor is noisy, Seriously affect the surrounding environment and the physical and mental health of construction workers; 2. The cost of the flexible shaft is high, and in the working condition where the working position is complicat...
