Problems solved by technology

[0002] The traditional rapping device includes a base, a hammer head and a hammer arm, wherein the hammer arm is hinged on the base, and the hammer head is installed on the lower part of the hammer arm, and the quality of the hammer head and the length of the hammer arm arm are fixed at the beginning of the design. It is determined, and generally cannot be changed, which makes the rapping mass and arm length of the rapping device invariable, and thus cannot provide variable rapping force
The rapping device with traditional structure is used in a wide range of occasions. At present, it is mainly used in electrostatic precipitators. In the actual application of electrostatic precipitators, the rapping device is often required to provide variable rapping force. The mass and arm length of the hammer arm are determined at the beginning of the design, and can only provide a specific rapping force, which cannot be changed arbitrarily according to actual needs. Requirements, for this reason, urgently need to solve the above-mentioned technical problems

Embodiment 1

[0018] Such as Figure 1~5 As shown, a rapping device with variable rapping mass and arm length includes a base 1, a hammer arm 2, a hammer head 3, a spindle 4, a motor 5, a mounting seat 6, a pushing hydraulic cylinder 7, and a crankshaft 8. Components such as crank arm 9, driven gear 10, hydraulic cylinder 11, mounting plate 12, driving gear 13 and driven pulley 14, wherein the base 1 is provided with a mandrel 4, a motor 5, a mounting seat 6 and a driving hydraulic pressure Cylinder 7 has a dovetail groove 1a along the horizontal direction on the base 1, the rear end of the mounting seat 6 is installed in the dovetail groove 1a, and can slide in the dovetail groove 1a, and the mounting seat 6 is arranged on the pushing On the right side of the hydraulic cylinder 7, the left side of the mounting seat 6 is fixed with the piston rod extending end of the hydraulic cylinder 7.

[0019] from Figure 1~5 It can be seen from the figure that 3 rapping units are arranged side by si...

Embodiment 2

[0022] from Image 6 It can be seen from the figure that at least 3 rapping units are arranged side by side on the mounting base 6 from left to right. In this embodiment, the number of rapping units is 4, and the specific number can be adjusted accordingly according to the actual situation. The rest of the structure of this embodiment is completely the same as that of Embodiment 1, and will not be repeated here.

[0023] The working principle of the present invention is as follows:

[0024] Control the push hydraulic cylinder 7 to make the mounting seat 6 slide horizontally, and make the driving gear 13 mesh with the driven gear 10 of one of the rapping units, driving the hammer head 3 corresponding to the driven gear 10 to rap; The hydraulic cylinder 11 is controlled to make the hammer arm 2 expand and contract in the sleeve 16, thereby changing the length of the rapping arm.

Abstract

The invention discloses a rapping device with variable rapping quality and arm length. Fixed; rapping units are arranged side by side on the mounting base, and each rapping unit is composed of crankshaft, crankarm, driven gear, hydraulic cylinder, mounting plate, hammer arm and hammer head, and the crankshaft is fitted on the crankshaft. Arm and driven gear, the extended end of the piston rod of the hydraulic cylinder is fixed to the hammer arm, and the hammer head is installed between the two hammer arms. The number of teeth of the driven gear of the above rapping units is the same, and the quality of the hammer head is different; it is installed behind the rapping unit. The mandrel is equipped with a driving gear and a driven pulley on the mandrel, the driving gear meshes with one of the driven gears, and the driven pulley is connected with the driving pulley. The invention has an ingenious concept and a simple structure, and can adjust the rapping mass and arm length according to actual needs to provide suitable rapping force and better meet the rapping requirements.

Description

technical field [0001] The invention relates to a rapping device, in particular to a rapping device with variable rapping mass and arm length for an electric precipitator. Background technique [0002] The traditional rapping device includes a base, a hammer head and a hammer arm, wherein the hammer arm is hinged on the base, and the hammer head is installed on the lower part of the hammer arm, and the quality of the hammer head and the length of the hammer arm arm are fixed at the beginning of the design. If it is determined, it is generally unchangeable, which makes the rapping mass and arm length of the rapping device invariable, and thus cannot provide variable rapping force. The rapping device with traditional structure is used in a wide range of occasions. At present, it is mainly used in electrostatic precipitators. In the actual application of electrostatic precipitators, the rapping device is often required to provide variable rapping force. The mass and arm length...
