Problems solved by technology

The technical problems existing in the existing hoisting frame are: the bridge frame can only be fixed in the air, and it cannot be leveled, which will easily cause the bridge frame to tilt, causing the internal cables to pile up due to the tilt, which is inconvenient for maintenance. And a safety accident occurs, because there is such a problem, it is necessary to improve the existing cable tray hoisting frame
[0003] After retrieval, the Chinese patent number is CN201420149628.3, which discloses a cable bridge hoisting piece, which includes a hoisting piece body. The top of the lifting piece body is provided with a top hoisting hole, and the bottom of the lifting piece body is provided with a bottom installation hole. Buckles are provided on the inner walls of both sides of the lifting part body, and the feature is that: the lifting part body is provided with whole-body reinforcing ribs extending along its length; however, the device still cannot get rid of the traditional frame structure. When installing the complete bridge frame, it is often impossible to erect it due to the small space when it is interspersed, so it can only be installed one by one.

Embodiment 1

[0030] refer to Figure 1-6 , a bridge hoisting device for hydropower installation, comprising a C-shaped hanging plate 1, the C-shaped hanging plate 1 comprising a bottom horizontal plate, a top horizontal plate parallel to it, and a side plate one perpendicular to the bottom horizontal plate, a side plate one There is a side plate 2 reserved between the top of the top and the top horizontal plate, and a gap 101 is opened on the end of the bottom horizontal plate away from the side plate 1, and a grooved slide plate 3 with an upward opening is welded in the gap 101, and the top end of the grooved slide plate 3 is open. There are equidistantly distributed crossbeams 2 fixed at the center, and an L-shaped flashboard 11 is slidably connected in the chute of the chute of the grooved slide plate 3, and equidistantly distributed stops are reserved near the middle of the bottom surface of the flashboard 11. Back teeth 8, and the groove bottom of the grooved slide plate 3 has a strip...

Embodiment 2

[0039] refer to Figure 1-2 , a kind of bridge hoisting equipment for hydropower installation. Compared with Embodiment 1, this embodiment also includes a card slot 13 on the inner wall of the vertical plate of the insert plate 11 near the middle, and a protrusion is fixed on the bottom of the card slot 13 .

[0040] Wherein, a compression spring 14 is sleeved on the outer wall of the protrusion, and a pressure block 12 is fixed on the end of the compression spring 14 away from the protrusion.

[0041] Working principle: When in use, the side of the insert plate 11 can have a continuous pressing force when it is close to the bridge body, avoiding the wear of the non-return teeth 8 at the bottom due to frequent weak shaking, and improving the continuous locking effect .

Abstract

The invention belongs to the technical field of power installation, particularly relates to a bridge frame hoisting device for water and electricity installation. and aims to solve a problem that a gap formed in an existing bridge hoisting device is consistent with the width of a bridge, the bridge is difficult to penetrate through in the penetrating and inserting process. The bridge frame hoisting device comprises a C-shaped hanging plate, wherein the C-shaped hanging plate comprises a bottom transverse plate, a top transverse plate parallel to the bottom transverse plate and a first side plate perpendicular to the bottom transverse plate, wherein a second side plate is reserved between a top end of the first side plate and the top transverse plate, a notch is formed in an end, away fromthe first side plate, of the bottom transverse plate, a groove-shaped sliding plate with an upward opening is welded in the notch, cross beams distributed at equal intervals are fixed to an opening ina top end of the groove-shaped sliding plate, and an inserting plate of an L-shaped structure is slidably connected into a sliding groove in a sliding groove of the groove-shaped sliding plate. The bridge frame hoisting device is advantaged in that bridge bodies with different widths can be clamped, mounting, dismounting and adjusting are convenient and rapid, and special tools are not needed.

Description

technical field [0001] The invention relates to the technical field of electric power installation, in particular to a bridge hoisting device for hydropower installation. Background technique [0002] The cable tray is used to place cables in the air. Its structure is divided into trough type, tray type, ladder frame type, grid type, etc. Its installation methods include support arm installation type and hoisting type. The hoisting bridge is connected on the ceiling by the hoisting frame. The existing hoisting frame includes a bridge frame, a mounting plate and a stay rope connected between them. The mounting plate is provided with expansion screws, and the expansion screws are used to be connected with the ceiling. The technical problems existing in the existing hoisting frame are: the bridge frame can only be fixed in the air, and cannot be leveled, which will easily cause the bridge frame to tilt, and the internal cables will be piled up due to the tilt, which is inconven...
