Abstract
The utility model discloses a transmission device of a tower crane turning system. The transmission device of the tower crane turning system comprises a turning support platform body (1), a planet gear motor (5), wherein the turning support platform body (1) is composed of an upper turning platform (2) and a lower turning platform (4), the upper turning platform (2) is connected with the lower turning platform (4) through a turning support (3) in a rotating mode, the planet gear motor (5) is arranged on the upper turning platform (2) through an installing seat (8), and the planet gear motor (5) drives the turning support (3) to connect in a rotating mode. The transmission device of the tower crane turning system is characterized in that a motor (7) is arranged on the upper turning platform, and the motor (7) is connected with the planet gear motor (5) through the transmission device in a driving mode. The transmission device of the tower crane turning system solves the problems that coupling transmission is adopted in the transmission device of an existing tower crane steel turning system, not only is an installing space of a certain height required, but also the transmission device of the tower crane turning system is not easy to fix and accordingly safe hazard is caused in the case of heavy weather such as strong wind.
Description
Technical field
The utility model relates to tower machine component device technical field, is specifically related to tower machine rotary system driving device.
Background technology
The tower machine, it is our said tower crane, be called again tower crane, it is a kind of weight-lifting equipment for building operation, the rising arm of tower machine is realized the revolution of rising arm usually by the rotation of upper rotary platform of revolution brace table, generally the driving the upper rotary platform by reductor and realize of revolution brace table, at present, used tower machine on the market, usually there is a problem, the driving device that is the tower machine generally adopts electrical motor to drive the type of drive of planetary reducing motor by coupler, but because the common higher above-mentioned type of drive of the height of tower machine needs enough height could adopt above-mentioned mounting means, such as strong wind weather undoubtedly, driving device is difficult for fixing, has brought certain potential safety hazard for the work of tower machine.
Summary of the invention
The technical problems to be solved in the utility model provides tower machine rotary system driving device, and the driving device that this technical scheme efficiently solves existing tower machine steel rotary system adopts shaft coupling transmission.The installing space problem that not only needs certain altitude, and such as inclement weathers such as strong wind, be difficult for fixing, the problem of potential safety hazard easily caused.
The utility model is achieved through the following technical solutions:
Tower machine rotary system driving device, comprise revolution brace table body (1), planetary reducing motor (5), revolution brace table body (1) comprises upper rotary platform (2), lower turn table (4), upper rotary platform (2) supports (3) by revolution and is rotationally connected with lower turn table (4), upper rotary platform (2) is equipped with planetary reducing motor (5) by mount pad (8), planetary reducing motor (5) drives revolution support (3) and is rotationally connected, it is characterized in that: described upper rotary platform (2) also is provided with electrical motor (7), and electrical motor (7) drives with planetary reducing motor (5) by driving device (9) and is connected.
The further Technological improvement plan of the utility model is:
Described driving device (9) is belt or is chain.
The further Technological improvement plan of the utility model is:
Also be provided with revolution killer (6) on the described revolution brace table body (1).
The utility model compared with prior art, have following obvious advantage: the utility model is with the drive mechanism of existing rotary system, change into belt transmission structure, not only lowered the setting height(from bottom) of driving device, also improved the inherently safe performance of tower machine simultaneously.The utility model is simple in structure, design science, cost are low, is convenient to promote the use of.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises revolution brace table body 1, planetary reducing motor 5, revolution brace table body 1 comprises upper rotary platform 2, lower turn table 4, upper rotary platform 2 is rotationally connected with lower turn table 4 by revolution support 3, upper rotary platform 2 is equipped with planetary reducing motor 5 by mount pad 8, planetary reducing motor 5 drives revolution support 3 and is rotationally connected, upper rotary platform 2 also is provided with electrical motor 7, electrical motor 7 drives with planetary reducing motor 5 by driving device 9 and is connected, described driving device 9 is belt, or be chain, also be provided with revolution killer 6 on the described revolution brace table body 1.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
