Abstract
The invention discloses a mechanical bridge section expanding mechanism which comprises an oil cylinder fixing seat, a first pin shaft, an oil cylinder, a second pin shaft, a triangular support fixing seat, a third pin shaft, a fourth pin shaft, a triangular support, a connecting rod, a fifth pin shaft and a connecting rod fixing seat. The oil cylinder fixing seat is fixed to the middle portion of a first bridge section. The oil cylinder is arranged between the oil cylinder fixing seat and the triangular support. The triangular support fixing seat is fixed to the middle portion of the first bridge section, a hinging point is flushed with one end of the first bridge section, and the triangular support is connected with the triangular support fixing seat through the third pin shaft. The connecting rod fixing seat is fixed to the middle portion of a second bridge section, one end of the connecting rod is connected with the connecting rod fixing seat through the fifth pin shaft, and the other end of the connecting rod is connected with the triangular support through the fourth pin shaft. The oil cylinder extends out to drive the triangular support and the connecting rod to move, so that the second bridge section is overturned by 180 degrees. The mechanical bridge section expanding mechanism has the beneficial effects when the bridge sections are expanded, the requirement for the space height is low, and the expanding mechanism uses the oil cylinder as power and is simple and reliable in structure.
Description
Technical field
The present invention relates to a kind of mechanized bridge bridge joint development mechanism.
Background technology
Current mechanized bridge bridge joint expansion mode is upward turnover type, and upward turnover type has bigger requirement in spatial altitude direction, and overturns Hou Xu connection mechanism, and the activity duration is longer.
Summary of the invention
The lower convertible mechanized bridge bridge joint development mechanism that the present invention provides a kind of structure simple, easy to operate. Lower convertible that the requirement of spatial altitude direction is lower, after being saved by turning unfolding mechanism deploying bridge, bridge joint top is to top contact, it is not necessary to connection mechanism, structure is simple, and the activity duration is short.
The present invention is achieved by the following scheme. It comprises oil cylinder fixing base, bearing pin one, oil cylinder, bearing pin two, A-frame permanent seat, bearing pin three, bearing pin four, A-frame, connecting rod, bearing pin five, connecting rod permanent seat.
Oil cylinder fixing base is welded in the middle of bridge joint one, and oil cylinder one end is connected with oil cylinder fixing base by bearing pin one, and the other end is connected with A-frame by bearing pin two; A-frame permanent seat is welded in the middle of bridge joint one, and it is concordant that twisted point saves one end with bridge, and A-frame is connected with A-frame permanent seat by bearing pin three; Connecting rod permanent seat is welded in the middle of bridge joint two, and connecting rod one end is connected with connecting rod permanent seat by bearing pin five, and the other end is connected with A-frame by bearing pin four.
Principle of work:
Oil cylinder stretches out, driving A-frame to rotate around bearing pin three, A-frame rotation forces link work, link work drives the connecting rod permanent seat motion being fixed on bridge joint two, bridge joint two is rotated around the connection twisted point of two bridge internodes, thus realizes bridge and save 2 180 �� of turning unfoldings; Oil cylinder is regained, and drives A-frame to rotate around bearing pin three, and drivening rod motion, link work drives bridge joint two to rotate around the connection twisted point of two bridge internodes, thus the upset realizing bridge joint two is regained.
The present invention has following advantage:
1. bridge joint expansion time space height direction requires lower;
2. bridge joint top is to top contact, it is not necessary to connection mechanism;
3. development mechanism take oil cylinder as power, and its structure is simple, reliable;
4. can realize expansion upset and the folded turnover of 180 ��.
Accompanying drawing explanation
The folded state schematic diagram of a kind of mechanized bridge bridge joint development mechanism of accompanying drawing 1 the present invention;
The working state schematic representation of a kind of mechanized bridge bridge joint development mechanism of accompanying drawing 2 the present invention;
The expansion view of a kind of mechanized bridge bridge joint development mechanism of accompanying drawing 3 the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention done detailed explanation:
As shown in Figure 1, a kind of mechanized bridge bridge joint development mechanism device of the present invention, comprises oil cylinder fixing base 1, bearing pin 1, oil cylinder 3, bearing pin 24, A-frame permanent seat 5, bearing pin 36, bearing pin 47, A-frame 8, connecting rod 9, bearing pin 5 10, connecting rod permanent seat 11.
As shown in Figure 1, 2, 3, oil cylinder fixing base 1 is fixed in the middle of bridge joint one, and oil cylinder 3 one end is connected with oil cylinder fixing base 1 by bearing pin 1, and the other end is connected with A-frame 8 by bearing pin 24; A-frame permanent seat 5 is welded in the middle of bridge joint one, and it is concordant that twisted point saves one end with bridge, and A-frame 8 is connected with A-frame permanent seat 5 by bearing pin 36; Connecting rod permanent seat 11 is fixed in the middle of bridge joint two, and connecting rod 9 one end is connected with connecting rod permanent seat 11 by bearing pin 5 10, and the other end is connected with A-frame 8 by bearing pin 47. Oil cylinder 3 stretches out, driving A-frame 8 to rotate around bearing pin 36, A-frame 8 rotation forces connecting rod 9 moves, and connecting rod 9 moves and drives the connecting rod permanent seat 11 being fixed on bridge joint two to move, bridge joint two is rotated around the connection twisted point of two bridge internodes, thus realizes bridge and save 2 180 �� of turning unfoldings. Folding removal process is contrary with expansion process.
