Abstract

The invention relates to a bridge crane additionally provided with a prestressed reinforcement. The bridge crane comprises a lifting mechanism, an operating mechanism and a frame mechanism. The frame mechanism comprises a main girder and an end girder connected with the girder. At least one prestressed reinforcement is arranged between an upper grider and a lower grider of the main girder. Both ends of the prestressed reinforcement are respectively connected with a hydraulic cylinder through couplings. The hydraulic cylinder is connected with a driving control system. After the bridge crane adopts the technical scheme, as at least one prestressed reinforcement is arranged between the upper grider and the lower grider of the main girder, when acting forces are applied to both ends of the prestressed reinforcement, the main girder can be slightly hogged upwards and at the time, mainly the prestressed reinforcement of the frame mechanism of the crane is stressed, such that the stresses on other steel materials of the frame mechanism are reduced, and thus, the steel consumption of the part of the frame mechanism can be greatly reduced and the cost is saved.

Description

A kind of crane in bridge type that installs deformed bar additional
Technical field
The present invention relates to a kind of crane in bridge type, specifically relate to the strong crane in bridge type of a kind of stiffness of structural member.
Background technology
Existing crane in bridge type, for increasing the whole stressing conditions of vehicle frame mechanism, common way is to increase steel to support, and has increased the steel consumption of crane in bridge type so greatly, thus the construction cost that increases greatly.
Summary of the invention
The purpose of this invention is to provide the crane in bridge type that adds deformed bar that a kind of rigidity is strong, save steel.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The present invention includes lifting mechanism, operating unit and vehicle frame mechanism; Described vehicle frame mechanism is made up of girder and the coupled end carriage that connects; Between the upper beam of said girder and underbeam, at least one deformed bar is set; The two ends of deformed bar connect hydraulic actuating cylinder through coupler respectively, and hydraulic actuating cylinder connects driving control system.
Described girder is two girder crane span structures or single girder crane span structure.
Between the upper beam of said girder and underbeam, two deformed bars are set.
Adopt the present invention of technique scheme, owing between the upper beam of girder and underbeam, at least one deformed bar is set, when the two ends at deformed bar apply application force; Girder can slightly upwards arch upward; At this moment, the vehicle frame mechanism of hoisting crane is mainly stressed by deformed bar, has reduced the stressed of other steel of vehicle frame mechanism; Thereby can significantly reduce the steel consumption of vehicle frame mechanism part, save cost.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present invention.
The specific embodiment
As shown in Figure 1; The present invention includes lifting mechanism, operating unit and vehicle frame mechanism; Described vehicle frame mechanism is made up of girder 1 and the coupled end carriage that connects, and in the present invention, between the upper beam 2 of girder 1 and underbeam 3, at least one deformed bar 4 is set; The two ends of deformed bar 4 connect hydraulic actuating cylinder 6 through coupler 5 respectively, and hydraulic actuating cylinder 6 connects driving control system.After driving control system sent control command, the output shaft of hydraulic actuating cylinder 6 stretched out, and this moment, deformed bar 4 upwards arched upward, and under this effect, girder 1 also slightly upwards arches upward.
Need to prove that the girder 1 among the present invention both can two girder crane span structures, also can single girder crane span structure.In addition, the upper beam and 4 quantity of the deformed bar between the underbeam that are arranged on girder can be merely one, also can be two.
Principle of the present invention is: owing between the upper beam of girder 1 and underbeam, at least one deformed bar 4 is set; When the two ends at deformed bar 4 apply application force, girder 1 can slightly upwards arch upward, at this moment; The stressed of crane locomotive frame mechanism mainly born by deformed bar; Reduce the stressed of other steel of vehicle frame mechanism, thereby can significantly reduce the steel consumption of vehicle frame mechanism part, saved cost.
