Abstract
The utility model discloses a hoister for tower crane hoisting. The hoister comprises a motor, a speed reducer and a winding drum which are successively connected, wherein a steel wire rope is wound on the winding drum, the motor is connected with the speed reducer through a coupling, a brake is arranged at the periphery of the coupling, the output shaft of the speed reducer is arranged in the winding drum in a penetrating manner, a hoisting height limiter is arranged at the tail end of the output shaft of the speed reducer, the speed reducer is positioned on the left side of the motor, the winding drum is positioned on the back side of the motor, and the hoisting height limiter is positioned on the right side of the winding drum. The hoister is used with the tower crane coordinately and is used on the hoisting machine of the tower crane, and the requirements on hoisting speed and hoisting quality can be satisfied during hoisting. The hoisting height limiter mounted on the hoister can be used for ensuring the performance and the safety of the hoisting machine of the tower crane, preventing accidents from occurring during hoisting operation, and ensuring the safety of hoisting. The arrangements of the motor, the winding drum and the speed reducer in the hoister are more compact, the occupied space is small, and the mounting and the use are convenient.
Description
Technical field
The utility model relates to a kind of winch, particularly relates to a kind of tower crane lifting winch.

Utility model content
In view of the shortcoming of above prior art, the purpose of this utility model is to provide a kind of tower crane lifting winch, uncontrollable and cannot fully guarantee performance and the safety problem of tower crane lifting machinery for solving prior art tower crane lifting.
For achieving the above object, the utility model adopts following technical scheme:
A kind of tower crane lifting winch, comprise the electrical motor, retarder and the reel that connect successively, lay winding wire ropes on described reel, described electrical motor is connected with retarder through coupler, described coupler periphery is provided with drg, the output shaft of described retarder is located in described reel, the end of described reducer output shaft is provided with hoisting depth limiting device, described retarder is positioned at the left side of electrical motor, described reel is positioned at the rear side of described electrical motor, and described hoisting depth limiting device is positioned at the right side of described reel.
Preferably, described electrical motor, retarder and reel are C type and arrange.
Preferably, described drg is two symmetrically arranged circular arc brake plates.
Preferably, described hoisting depth limiting device is also connected with controller, so that the hoisting depth of automatic control tower machine.
Preferably, described electrical motor, retarder and reel are installed on a firm banking.
Above-mentioned tower machine refers to tower crane.Above-mentioned wire rope suspensioning has suspension hook.
Above-mentioned hoisting depth killer, also referred to as height limitator, with height and the speed of control tower machine lifting heavy, and reaches spacing effect.
Winch of the present utility model and tower crane support the use, for the elevating gear of tower crane, hoisting speed can meet lifting time and the requirement of quality, the hoisting depth limiting device that this winch is equipped with, can guarantee performance and the safety of tower crane lifting machinery, prevent lifting operation generation accident, guarantee the safety promoting.In this winch the position of electrical motor, reel and retarder arrange compacter, take up an area little and easy to install.

Tower crane lifting winch as shown in Figure 1, comprise the electrical motor 1, retarder 2 and the reel 3 that connect successively, lay winding wire ropes 4 on described reel, described electrical motor 1 is connected with retarder 2 through coupler, described coupler periphery is provided with drg 5, the output shaft 6 of described retarder is located in described reel, the end 7 of described reducer output shaft is provided with hoisting depth limiting device 8, described retarder 2 is positioned at the left side of electrical motor 1, described reel 3 is positioned at the rear side of described electrical motor 1, and described hoisting depth limiting device 8 is positioned at the right side of described reel 3.
Preferably, described electrical motor, retarder and reel are C type and arrange.
Preferably, described drg is two symmetrically arranged circular arc brake plates.
Preferably, described hoisting depth limiting device is also connected with controller (not shown), so that the hoisting depth of automatic control tower machine.
Preferably, described electrical motor 1, retarder 2 and reel 3 are installed on a firm banking 9.
Above-mentioned tower machine refers to tower crane.Above-mentioned wire rope suspensioning has suspension hook.
Above-mentioned hoisting depth killer, also referred to as height limitator, with height and the speed of control tower machine lifting heavy, and reaches spacing effect.
Winch of the present utility model and tower crane support the use, for the elevating gear of tower crane, hoisting speed can meet lifting time and the requirement of quality, the hoisting depth limiting device that this winch is equipped with, can guarantee performance and the safety of tower crane lifting machinery, prevent lifting operation generation accident, guarantee the safety promoting.In this winch the position of electrical motor, reel and retarder arrange compacter, take up an area little and easy to install.
In sum, tower crane lifting of the present utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization with winch.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
