Description

Technical Field

[0001] This utility model relates to the field of vibratory rod technology, and in particular to a hydraulic rotating mechanism. Background Technology

[0002] To improve the quality of concrete pouring, a concrete vibrator can be used to vibrate the concrete and eliminate air bubbles. For example, Chinese patent CN110792019A discloses a concrete vibrator, including a base plate and a mounting base. The mounting base is fixedly installed on the base plate. A first handrail is installed at an angle on one side of the mounting base, and a second handrail is installed at an angle on the other side. The base plate includes a steel plate and a protective bottom shell. The steel plate is fixed to the bottom of the protective bottom shell. Multiple vibration motors are fixedly installed between the protective bottom shell and the mounting base. Multiple through holes are opened on the base plate and the mounting base, through which vibrating rods pass. A support frame is fixedly installed on the surface of the mounting base by bolts. The support frame consists of a crossbeam, a left beam, and a right beam. The left and right beams are perpendicular to the mounting base. The two ends of the crossbeam are fixedly connected to the tops of the left and right beams, respectively. A fixing block is installed inside the crossbeam, and a pressure plate is set below the fixing block. A telescopic hydraulic cylinder is installed between the fixing block and the pressure plate. The lower end of the pressure plate is fixedly connected to the upper end of the vibrating rod.

[0003] The hydraulic vibrator of existing vibrators usually only has a fixed vibration angle during use, and can only be used on flat construction surfaces. For construction on uneven surfaces such as corners, the construction angle cannot be flexibly adjusted. Utility Model Content

[0004] The purpose of this utility model is to provide a hydraulic rotating mechanism to solve the problem that the fixed construction angle of existing tamping equipment makes it impossible to carry out construction on non-flat surfaces.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hydraulic rotating mechanism, comprising:

[0006] The speed reduction module includes a housing, a drive motor, a worm, a worm wheel, and an output end cover. The output end of the drive motor is connected to the worm, and the worm wheel is located inside the housing. The worm meshes with the worm wheel, and the worm wheel is used to drive the output end cover to rotate.

[0007] The bucket connector includes a connecting seat and a joint. The connecting seat is fixedly installed on the housing. The joint passes through the reduction module. The joint is provided with an oil inlet channel and an oil return channel. The bottom of the oil inlet channel extends to the side wall of the joint to form an oil inlet. The bottom of the oil return channel extends to the side wall of the joint to form an oil return port.

[0008] The connecting flange is fixedly installed on the output end cover.

[0017] As a further description of the above technical solution:

[0018] The connecting plate is provided with a reinforcing protrusion, and the connecting hole is located on the reinforcing protrusion.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, the connecting seat in the bucket connector is used for connecting the bucket arm of equipment such as excavators. The oil pipeline on the bucket arm can be connected to a joint, and the hydraulic oil is transported and returned through the oil inlet channel and the oil return channel. The hydraulic rotating mechanism does not block the transport of hydraulic oil, thus supplying hydraulic oil to the hydraulic vibrator.

[0021] 2. In this utility model, the connecting flange on the deceleration module is used to connect to the platform with the vibrator. The rotation of the output end cover drives the platform to rotate as a whole, thereby adjusting the construction angle and effectively coping with construction on flat and uneven surfaces.

[0031] The reduction module 1 includes a housing 11, a drive motor 12, a worm, a worm wheel, and an output end cover 13. The output end of the drive motor 12 is connected to the worm. The worm wheel is disposed inside the housing 11. The worm meshes with the worm wheel, and the worm wheel is used to drive the output end cover 13 to rotate.

[0032] The bucket connector 2 includes a connecting seat 21 and a connector 22. The connecting seat 21 is fixedly installed on the housing 11. The connector 22 passes through the reduction module 1. The connector 22 is provided with an oil inlet channel 221 and an oil return channel 222. The bottom of the oil inlet channel 221 extends to the side wall of the connector 22 to form an oil inlet 2211. The bottom of the oil return channel 222 extends to the side wall of the connector 22 to form an oil return port 2221.

[0033] Connecting flange 3 is fixedly installed on output end cover 13.

[0034] The connecting base 21 includes a base plate 211 and two parallel connecting plates 212, each with a connecting hole 2121. The connecting plate 212 is connected to the boom of an excavator or similar equipment through the connecting hole 2121.

[0035] Working principle: The connecting seat 21 in the bucket connector 2 is used for connecting the bucket arm of equipment such as excavators. The oil pipeline on the bucket arm can be connected to the connector 22. The hydraulic oil is transported and returned through the oil inlet channel 221 and the oil return channel 222. The hydraulic rotating mechanism does not block the supply of hydraulic oil, thus supplying hydraulic oil to the hydraulic vibrator. The connecting flange 3 on the reduction module 1 is used to connect to the platform with the vibrator. The rotation of the output end cover 13 drives the entire platform to rotate, realizing the rotation adjustment of the construction angle, effectively dealing with construction on flat and uneven surfaces.
