Abstract
The utility model discloses a lifting device for opening a dam trash rack. The lifting device for opening the dam trash rack comprises lifting lug plates (2), the lifting lug plates (2) are connected with a lifting rod (1), a locking plate (4) is arranged on the lifting rod (1), and the locking plate (4) is connected with a flying ring (3). According to the lifting device for opening the dam trash rack, a common I-shaped beam structure is replaced by round steel, the size and the weight of the lifting device are reduced, and operation is more convenient. Meanwhile, the total work amount of the manufacturing of the lifting device is reduced to a large extent, the borne load of the lifting device is equal to that of a lifting device of the same type, and economy and structural stress are good. The lifting device for opening the dam trash rack is especially suitable for small size dam projects, saves materials and manufacturing working amount, and is low in manufacturing cost and good in economy.
Description
Technical field
the utility model relates to a kind of for opening the suspender of dam drain grating, belongs to dam headstock gear outfitting tool technical field.
Background technology
along with socioeconomic development, water demand further strengthens, and due to the skewness of water resource, makes regional water diversion project increase gradually.Because the dirt content in river is different, at intake, usually some trashracks can be set.The unlatching of trashrack or close is generally operated by headstock gear, and a connector is arranged in the junction of headstock gear and trashrack, is called suspender.Current suspender is a kind of i iron weldment, and structure is heavier, and its economy, practicality are poor.
Summary of the invention
the purpose of this utility model is, provides a kind of for opening the suspender of dam drain grating.With a kind of simple in structure, reasonable stress, used light and handy suspender easily to substitute the heavier suspender of existing structure.
the technical solution of the utility model:
a kind ofly for opening the suspender of dam drain grating, comprise the shackle plate be connected with drain grating, shackle plate is connected with suspension rod, and suspension rod is provided with lockplate, and lockplate is connected with suspension ring.
in aforementioned suspender, described shackle plate is two blocks of symmetrically arranged steel plates, and shackle plate is provided with connecting hole and screwed hole; Two shackle plates are symmetrically welded at the suspension rod lower end.
in aforementioned suspender, described lockplate is the rectangular steel plates that a centre is provided with through hole.
in aforementioned suspender, described suspension rod is one section straight round bar, and weld with two shackle plates respectively both sides, suspension rod bottom; The suspension rod upper end passes and welds with lockplate from the through hole of lockplate.
in aforementioned suspender, described suspension rod upper end passes from the through hole of lockplate, is welded with two locking floors between the upper plane of the both sides of suspension rod upper end and lockplate.
in aforementioned suspender, described locking floor is the triangle steel plate; Be symmetrically welded between the upper plane of suspension rod upper end and lockplate.
in aforementioned suspender, described suspension ring are that reinforcing bar bends the U-shaped suspension ring that form, the overlapping welding of two straight flanges of U-shaped suspension ring and suspension rod upper end, the upper plane-welding of the two ends of U-shaped suspension ring and lockplate.
compared with prior art, the utility model adopts round steel to replace common i-shaped beams structure, has reduced the suspender volume and weight, operation is easier.Simultaneously, significantly reduced the whole project that suspender is made, and its to bear load also suitable with suspender of the same type, economy, structure stress be all better.Be specially adapted to small-sized dam engineering, save material and fabrication amount, cost of manufacture is low, better economy.
The accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is the structural representation of lockplate and locking floor.
being labeled as in accompanying drawing: the 1-suspension rod, the 2-shackle plate, the 3-suspension ring, the 4-lockplate, 5-locks floor.
The specific embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
a kind of for opening the suspender of dam drain grating, as shown in Figure 1.Comprise the shackle plate 2 be connected with drain grating, shackle plate 2 is connected with suspension rod 1, and suspension rod 1 is provided with lockplate 4, and lockplate 4 is connected with suspension ring 3.Described shackle plate 2 is two blocks of symmetrically arranged steel plates, and shackle plate 2 is provided with connecting hole 6 and screwed hole 7; Two shackle plates 2 are symmetrically welded at suspension rod 1 lower end.Described lockplate 4 is the rectangular steel plates (see figure 2) that a centre is provided with through hole 8.Described suspension rod 1 is one section straight round bar, and weld with two shackle plates 2 respectively suspension rod 1 both sides, bottom; Suspension rod 1 upper end passes and welds with lockplate 4 from the through hole 8 of lockplate 4.Described suspension rod 1 upper end passes from the through hole 8 of lockplate 4, is welded with two locking floors 5 between the both sides of suspension rod 1 upper end and the upper plane of lockplate 4.Described locking floor 5 is triangle steel plate (see figure 2); Be symmetrically welded between the upper plane of suspension rod 1 upper end and lockplate 4.The U-shaped suspension ring that described suspension ring 3 form for reinforcing bar bends, two straight flanges of U-shaped suspension ring and the suspension rod 1 overlapping welding in upper end, the upper plane-welding of the two ends of U-shaped suspension ring and lockplate 4.
the utility model adopts round steel to replace common i-shaped beams structure, has reduced the suspender volume and weight, operation is easier.Simultaneously, significantly reduced the whole project that suspender is made, and its to bear load also suitable with suspender of the same type, economy, structure stress be all better.Be specially adapted to small-sized dam engineering, save material and fabrication amount, cost of manufacture is low, better economy.
