Abstract

The invention discloses an upper bracket structure of a tower crane and the tower crane. The upper bracket structure comprises a box body 2 and two slewing mechanisms 1 mounted on the box body 2, wherein the two slewing mechanisms 1 are arranged on the same side of an upper bracket. According to the upper bracket structure, the two slewing mechanisms are arranged on the same side of the upper bracket, so that space usage is reduced, the platform layout is compact and reasonable, the blanking area of an upper bracket cover plate is reduced, and the material utilization efficiency is increased; and the slewing mechanisms are arranged on one side of the upper bracket, and a cab platform is arranged on the other side of the upper bracket, so that weight distribution is reasonable, and the working stability and reliability of the tower crane are improved.

Description

A kind of upper bracket structure of tower crane and tower crane
Technical field
The present invention relates to a kind of connection structure of flat-top tower crane crane arm, specifically a kind of upper bracket structure of tower crane, belong to flat-top tower crane crane arm technical field.
Background technology
Upper bracket is as the important composition parts of in tower crane, be mainly used in connecting undersetting, tower cap, equilibrium arm and crane arm, existing upper bracket structure as shown in Figure 1, entirety is box typed structure, primarily of casing 2, is arranged on swing type mechanism 1 on casing 2 and upper bracket cover plate composition.Wherein, swing type mechanism 1 is made up of turning motor, rotary reducer etc., and two swing type mechanisms are distributed in upper bracket both sides, and realize the gyroscopic movement of upper bracket and tower machine with pivoting support engaged transmission.But there are the following problems in actual use
1, because swing type mechanism is distributed in both sides, make upper bracket cover plate materials degree of utilization low;
2, as shown in Figure 2, upper bracket takes up room greatly, and platform layout is not compact, and installation and transportation are inconvenient, and the swing type mechanism installation site as stretched out limits the layout of maintenance platform and driver's cab platform 3; And upper bracket side is swing type mechanism, opposite side is swing type mechanism and driver's cab, and weight distribution is unreasonable, can be partial to driver's cab side, have impact on stability and the reliability of the work of tower machine.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of upper bracket structure of tower crane, upper bracket cover plate blanking area can not only be reduced, improve stock utilization; And it is little to take up room, platform layout compact and reasonable, weight distribution is reasonable, can improve the stability of tower machine work, reliability.
To achieve these goals, the upper bracket structure of a kind of tower crane that the present invention adopts, comprise casing and be arranged on two swing type mechanisms on casing, described two swing type mechanisms are arranged on the same side of upper bracket.
Described swing type mechanism is primarily of turning motor and rotary reducer composition, and described turning motor is connected with rotary reducer.
A kind of tower crane, comprise upper bracket, undersetting, tower cap, equilibrium arm, crane arm and driver's cab platform, its special described upper bracket adopts above-mentioned upper bracket structure, and described driver's cab platform is distributed in the opposite side of upper bracket.
Described undersetting comprise be made up of cover plate and gusset casing, be welded on the main string of undersetting that casing surrounding saves for connection standard and be welded on the main string of undersetting for being connected the undersetting engaging lug seat of climbing support, the latter half of the main string of undersetting is fixed by gusset and casing, is connected between the main string of described undersetting by angle steel connecting rod.
The two ends of described angle steel connecting rod are connected with the main string of upper bracket by strand drilling bolt.
Compared with prior art, the present invention, by the swing type mechanism of two in upper bracket is placed on the same side, makes integral layout compacter, takes up room little, reduces upper bracket cover plate blanking area, improves stock utilization.Meanwhile, swing type mechanism and driver's cab are distributed in upper bracket both sides, and weight distribution is evenly reasonable, improves the stability of tower machine work, reliability.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing upper bracket;
Fig. 2 is the using state schematic diagram of existing upper bracket;
Fig. 3 is structural representation of the present invention;
Fig. 4 is using state schematic diagram of the present invention;
Fig. 5 is the structural representation of undersetting of the present invention.
In figure: 1, swing type mechanism, 2, casing, 3, driver's cab platform.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 3, a kind of upper bracket structure of tower crane, two swing type mechanisms 1 comprising casing 2 and be arranged on casing 2, it is characterized in that, described two swing type mechanisms 1 are arranged on the same side of upper bracket.
Described swing type mechanism 1 is primarily of turning motor and rotary reducer composition, and described turning motor is connected with rotary reducer.
A kind of tower crane, comprise upper bracket, undersetting, tower cap, equilibrium arm, crane arm and driver's cab platform 3, described upper bracket adopts above-mentioned upper bracket structure, and described driver's cab platform 3 is distributed in the opposite side of upper bracket, as shown in Figure 4.
As shown in Figure 5, described undersetting comprise be made up of cover plate and gusset casing, be welded on the main string of undersetting 4 that casing surrounding saves for connection standard and be welded on the main string 4 of undersetting for being connected the undersetting engaging lug seat 5 of climbing support, the latter half of the main string 4 of undersetting is fixed by gusset and casing, is connected between the main string 4 of described undersetting by angle steel connecting rod 6.Preferably, the two ends of described angle steel connecting rod 6 are connected with the main string 4 of upper bracket by strand drilling bolt, can be convenient to installing/dismounting.The deflection of this undersetting is little, can ensure the installation dimension requirement of the main string of undersetting and undersetting engaging lug seat, decreases the main string problem on deformation of undersetting in welding, transportation, substantially increases the installation effectiveness of tower machine.
From said structure, the present invention, by designing two swing type mechanisms in upper bracket the same side, reduces the blanking area of upper bracket cover plate, improves stock utilization; Meanwhile, for whole hoisting crane, driver's cab design is at the opposite side of upper bracket, and the casing of this side of upper bracket does not have sponson, and driver's cab platform shortens, and near upper bracket, platform and integrally layout compact and reasonable more, takes up room little; And swing type mechanism and driver's cab are distributed in upper bracket both sides, weight distribution is even, improves the stability of tower machine work, reliability.
