The utility model discloses pass through gear and slewing bearing with drive mechanism and mesh mutually, through the mode of two meshings, it is rotatory to drive slewing bearing by drive mechanism drive gear, has not only increased the meshing area for the transmission is more steady, and has greatly improved the transport and the bearing capacity of circulator.

Description

Large-tonnage forklift rotator

Technical Field

The utility model relates to a machinery transportation technical field, concretely relates to large-tonnage fork truck circulator.

Background

The forklift rotator is usually matched with containers such as a fork type hopper for use, can rapidly turn over goods in the containers by 360 degrees, and is widely applied to industries needing to turn over the hopper containers, such as food, chemical industry, article recovery, smelting and casting, and the like. However, in the prior art, the torque generated by the rotator is small due to the limit value of the transmission mechanism, and the requirement of carrying large-tonnage materials cannot be met, especially in the large-tonnage smelting and casting industry.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a large-tonnage fork truck circulator for smelting, casting trade.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the large-tonnage forklift rotator comprises a front bottom plate and a rear bottom plate, wherein the back surface of the front bottom plate is connected with the front surface of the rear bottom plate through a slewing bearing, the front surface of the front bottom plate is used for mounting a pallet fork device, and the back surface of the rear bottom plate is provided with a transmission mechanism which is meshed with the slewing bearing through a gear.

Furthermore, the transmission mechanism comprises two hydraulic transmission devices which are symmetrically arranged on the left side and the right side of the back surface of the rear bottom plate, and the hydraulic transmission devices are connected with hydraulic valves.

Preferably, the rear bottom plate is provided with a milling groove for mounting the transmission mechanism, and the transmission mechanism is wrapped by the rear bottom plate.

Preferably, a sealing ring is arranged around the slewing bearing, and a cover plate is arranged at the gear.

Preferably, the rear bottom plate adopts a hollow structure, and the front bottom plate adopts a non-hollow structure.

The utility model discloses pass through gear and slewing bearing with drive mechanism and mesh mutually, through the mode of two meshings, it is rotatory to drive slewing bearing by drive mechanism drive gear, has not only increased the meshing area for the transmission is more steady, and has greatly improved the transport and the bearing capacity of circulator.

Detailed Description

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

The large-tonnage forklift rotator shown in fig. 1-3 comprises a front bottom plate 1 and a rear bottom plate 2, wherein the back surface of the front bottom plate is connected with the front surface of the rear bottom plate through a slewing bearing 3, the front surface of the front bottom plate is used for mounting a pallet fork device, and the back surface of the rear bottom plate is provided with a transmission mechanism 4 which is meshed with the slewing bearing through a gear 42.

In specific use, partial working environment is more complicated, in order to reduce the circulator damage, increase of service life, drive mechanism 4 includes that two symmetries set up the hydraulic transmission 41 of the 2 back left and right sides of rear floor, hydraulic transmission is connected with hydrovalve 43, offer the milling flutes that are used for installing drive mechanism on the rear floor, wrap up drive mechanism through the rear floor, protect motor and whole drive mechanism among the drive mechanism, simultaneously slewing bearing 3 is provided with seal ring 5 all around to be provided with apron 6 in gear department, further protect the circulator.

The rear bottom plate 2 of the preferred embodiment adopts a hollow structure, so that the weight of accessories can be reduced, the comprehensive bearing capacity is improved, and meanwhile, the front bottom plate 1 adopts a non-hollow structure, so that the rear bottom plate has a longer service life in the metal smelting and casting production industry.

The above-mentioned embodiments are only to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
