Plug-in type vibrator

Abstract

The invention discloses a plug-in type vibrator comprising a motor and a joint installed at a motor front cover. Besides, the plug-in type vibrator also includes a locking mechanism arranged at the joint, a detachable joint connected with joint, and a segmented shaft connected with a rotor arranged in the motor. The locking mechanism consists of a plurality of reeds, an L-shaped lockpin, a lock catch, and a bolt. The detachable joint includes an inner joint, a flexible shaft, and a vibrating rod; the inner joint is plugged in the joint arranged at the motor front cover; the flexible shaft is arranged at the center inside the inner joint; and one end of the flexible shaft is opposite to the output shaft end of the plug-in type vibrator motor and the other end of the flexible shaft is connected with the vibrating rod. Because of the locking mechanism, the vibrating rod can be locked tightly and effectively; the detachable joint and the joint arranged at the front cover of the plug-in type vibrator motor are connected and the lock pin portion passing through the joints are abutted through the arc grooves, the square groove, and the annular groove that are formed in the surface of the inner joint, so that the joints are connected firmly without disengagement; and the vibrating rod can be replaced conveniently because of the detachable joint. And because the gear wheel unit is separated from the shaft, only the gear wheel needs to be replaced when maintenance is requirement, so that the cost is lowered.

Description

technical field [0001] The invention relates to a vibrator for concrete construction, in particular to an inserted vibrator. Background technique [0002] During the use of existing plug-in vibrators for concrete construction, lock pins are usually used to lock the vibrating rod. The front cover of the plug-in vibrator motor is connected to an external pipe, and an internal pipe is inserted into the external pipe. The tube is connected to the vibrating rod, and the vibrating rod is inconvenient to replace and inconvenient to use. [0003] When the plug-in vibrator for concrete construction is overturned or suspended, the lock pin is easy to rotate, and the vibrating rod cannot be locked, causing the lock pin to often fall off. However, measures such as binding with iron wires and ropes taken at the construction site, It is not convenient for the loading and unloading of the vibrating rod, and it also affects the overall aesthetics of the plug-in vibrator; in addition, after...

Problems solved by technology

[0002] During the use of existing plug-in vibrators for concrete construction, lock pins are usually used to lock the vibrating rod. The front cover of the plug-in vibrator motor is connected to an external pipe, and an internal pipe is inserted into the external pipe. The tube is connected to the vibrating rod, the vibrating rod is inconvenient to replace, and it is inconvenient to use

[0003] When the plug-in vibrator for concrete construction is overturned or suspended, the lock pin is easy to rotate, and the vibrating rod cannot be locked, causing the lock pin to often fall off. However, measures such as binding with iron wires and ropes taken at the construction site, It is not convenient for the loading and unloading of the vibrating rod, and it also affects the overall aesthetics of the plug-in vibrator; in addition, after the plug-in vibrator is used continuously for a period of time, the internal gears will be damaged at an accelerated rate due to lack of lubrication. The maintenance method of the plug-in vibrator is to disassemble the gear-related parts, lubricate the gears separately, and then install the disassembled parts, which brings great inconvenience to the construction site and even affects the construction process; In addition, the gears are wearing parts and need to be repaired frequently

Under certain conditions, the gear will fail. For this, the motor needs to be replaced and repaired, and the rotor should be replaced as a whole, which is inconvenient.
