Description
Technical Field
The utility model relates to the technical field of gate devices, in particular to a mechanical grabbing beam structure.
Background
In hydropower station engineering, the opening and closing of a porous gate and a trash rack are usually completed by adopting a mode that a movable hoist carries an automatic grabbing beam, and the common automatic grabbing beam comprises a hydraulic automatic grabbing beam and a mechanical automatic grabbing beam. In the prior art, the mechanical automatic grabbing beam is too complex and too cumbersome to work, so that the mechanical automatic grabbing beam cannot be accurately aligned and unhooked, and the working reliability of equipment is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a mechanical grabbing beam structure.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a roof beam structure is grabbed to machinery, includes the roof beam structure, rotate on the roof beam structure intermediate position and install the rope lifting device, the bilateral symmetry of rope lifting device is provided with the lifting hook, and the lifting hook is all installed in the bottom of roof beam structure, and the rope lifting device passes through connecting screw and links to each other with the lifting hook, and the nylon rope is all installed to rope lifting device butt end and oblique end.
The utility model further adopts a preferable scheme that: the tail end of each lifting hook is provided with a counterweight.
The utility model further adopts a preferable scheme that: two suspension ropes are symmetrically arranged on the upper surface of the beam frame and connected together through a pear-shaped ring.
Further preferred embodiments of the present invention: each lifting hook is provided with a lifting shaft.
The utility model has the following advantages: the utility model simplifies the operation through the rope lifter, solves the problem that the mechanical automatic grab beam cannot be accurately aligned and unhooked, and increases the reliability of the device.
Drawings
FIG. 1 is a schematic view of the hook process of the present invention in a front view;
FIG. 2 is a schematic front view of the unhooking process of the present invention;
in the figure: 1 beam frame, 2 lifting hooks, 3 connecting screws, 4 counterweights, 5 rope lifters, 6 nylon ropes, 7 hanging shafts, 8 sling ropes and 9 pear-shaped rings.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
According to fig. 1-2, a machinery grabbing beam structure, includes roof beam structure 1, rotate on the roof beam structure 1 intermediate position and install rope lifting device 5, the bilateral symmetry of rope lifting device 5 is provided with lifting hook 2, and lifting hook 2 all installs the bottom at roof beam structure 1, and rope lifting device 5 passes through connecting screw 3 and links to each other with lifting hook 2, and rope lifting device 5 flush end and oblique end all install nylon rope 6.
The tail end of each lifting hook 2 is provided with a counterweight 4.
Two suspension ropes 8 are symmetrically arranged on the upper surface of the beam frame 1, and the two suspension ropes 8 are connected together through a pear-shaped ring 9.
Each lifting hook 2 is provided with a lifting shaft 7.
The working principle is as follows: the hooking process comprises the following steps:
as shown in fig. 1. The 1 descends of roof beam structure, and behind the lifting hook 2 contacted the gate, to lifting nylon rope 6, lifting rope ware 5 links to each other with lifting hook 2 through connecting screw rod 3 to make lifting hook 2 keep the tilt state, roof beam structure 1 continues to descend, after lifting hook 2 contacted the gate on the girder web, loosens nylon rope 6, lifting rope ware 5 falls back, lifting hook 2 because the action of gravity resumes vertical state, and the hanging shaft 7 is in the perpendicular top of lifting hook 2 this moment, promotes roof beam structure 1, accomplishes the couple process.
Unhooking:
the grabbing beam lifts the gate to a placing position, the beam frame 1 moves downwards, the hanging shaft 7 is made to exit from an inner hole of the hanging hook 2, the nylon rope 6 is pulled downwards, the hanging hook 2 is made to be in an inclined state through the linkage of the rope lifting device 5 and the connecting screw rod 3, and as shown in figure 2, the hanging shaft 7 completely exits from the operation range of the hanging hook 2. And lifting the beam frame 1 to complete the unhooking process.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
