Abstract
The present invention provides a high-efficiency special offshore tower crane power transmission apparatus based on the problem of insufficient lifting capability of the existing special offshore tower crane. The high-efficiency special offshore tower crane power transmission apparatus comprises a base, an engine arranged on the base, a transfer case arranged on the base, a SAUER pump connected to the transfer case, and a power drive device gear pump connected to the SAUER pump, wherein the SAUER pump transfers pressure energy to the power drive device gear pump through a hydraulic oil pipe, the engine is connected to the transfer case, and a multi-stage planetary structure is arranged in the transfer case. According to the present invention, the structure design is reasonable, the operation is convenient, the effective conversion of the mechanical energy to the hydraulic energy and then to the mechanical energy is used, the high power output and the smooth operation of the equipment are ensured, the loss of the mechanical efficiency is effectively reduced, the efficiency of the power mechanism is substantially improved, and the lifting capability of the tower crane is improved; and the double insurance is arranged so as to effectively ensure the stable and safe operation of the lifting apparatus.
Description
Technical field
The present invention relates to a kind of Power Drive Unit, refers specifically to a kind of efficient tower crane actuating unit.
Background technology
With the fast development in international information epoch, the speed of each building trade is also being developed rapidly, and the built speed of each construction-engineering project is also constantly refreshing.At present, tower crane both domestic and external has preferably ensured the security performance in hoisting process, but the lifting of the efficiency of tower crane lifting is also to be improved.And the lifting of tower crane power transmission efficiency is the key point for ensureing tower crane integral hoisting ability and lifting efficiency, and it is the growth requirement in the epoch of having complied with；Wherein, because of the restriction of its use environment and the particularity of manipulating object, its hoisting power seems not enough to marine special tower crane especially, lifts its transmission efficiency and will greatly improve the overall lifting efficiency of tower crane and Lifting Capacity.Therefore, design is needed badly a kind of rational in infrastructure, easy to use, motility is strong, the actuating unit of the marine special tower crane with higher transmission efficiency.
The content of the invention
The present invention is for the not enough problem of existing marine special tower crane hoisting power, there is provided a kind of reasonable in design, easy to operate, it is easy to use, flexible, the motor-driven force actuators of efficient marine special tower.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of motor-driven force actuators of efficient marine special tower, including base, electromotor and transfer case on base, the SAUER pumps being connected with transfer case, the Power Drive Unit gear pump being connected with SAUER pumps, SAUER pumps are delivered to pressure energy on Power Drive Unit gear pump by hydraulic oil pipe；The electromotor is connected with transfer case, and multistage planet structure is provided with inside transfer case.
Used as the prioritization scheme of the present invention, the transfer case has self-locking device.
As the prioritization scheme of the present invention, ratchet braking is installed on the base.
Used as the prioritization scheme of the present invention, the SAUER pumps connect gear pump by excessive flange.
The invention has the beneficial effects as follows：Present configuration is reasonable in design, simple operation, and using mechanical energy to hydraulic energy effective conversion of mechanical energy is arrived again, ensure that powerful output is steady with equipment operation, the loss of mechanical efficiency is effectively reduced, the efficiency of actuating unit is substantially increased, the hoisting power of tower crane is improved；Double insurance is set, lifting device has been effectively ensured and steadily, has safely been run.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
In figure：1- bases, 2- electromotors, 3- transfer cases, 4-SAUER pumps, the excessive flanges of 5-, 6- gear pumps.
Specific embodiment
The present invention and its effect are further elaborated below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of motor-driven force actuators of efficient marine special tower, including base 1, electromotor 2 and transfer case 3 on base 1, the SAUER pumps 4 being connected with transfer case 3, the Power Drive Unit gear pump 6 being connected with SAUER pumps 4, transfer case 3 is transferred energy to by electromotor 1 in the present invention, again high-revolving mechanical energy is delivered to into SAUER pumps 4 by transfer case 3, finally by SAUER pumps 4 pressure energy is delivered on Power Drive Unit gear pump 6 by hydraulic oil pipe, realize that mechanical energy arrives again effective conversion of mechanical energy to hydraulic energy, ensure that powerful output is steady with equipment operation, effectively reduce the loss of mechanical efficiency, greatly improve the efficiency of actuating unit, improve the hoisting power of tower crane.SAUER pumps 4 are connected by excessive flange 5 with gear pump 6；Electromotor 2 is connected with transfer case 3, and multistage planet structure is provided with inside transfer case 3；Transfer case 3 has self-locking device in the present invention, and ratchet braking is arranged on base 1, and double insurance is safer in operation to ensure lifting device tower crane.
Above example is only exemplary, can't limit to the present invention, it should be pointed out that for a person skilled in the art, and under technology provided by the present invention enlightenment, other equivalent modifications made and improvement are regarded as protection scope of the present invention.
