Description

Prevent roof beam dog that falls convenient to installation

Technical Field

The utility model relates to a railway bridge construction equipment technical field, more specifically the theory that says so relates to a roof beam dog prevents falling convenient to installation.

Background

The high-speed railway bridge structure frequently suffers from different degrees of damage due to insufficient anti-seismic performance and improper selection of anti-seismic measures, so that obstacles are additionally arranged for anti-seismic rescue, reconstruction work after disasters is very difficult, the anti-falling beam stop block can be installed at the lower end of the bridge in order to reduce the problems, and the anti-vibration effect of the high-speed railway bridge can be improved through the limiting effect of the anti-falling beam stop block and the upper end of the bridge pier.

Among the prior art, general roof beam dog that prevents falling passes through the bolt and installs in the reservation hole of bridge below, can carry on spacingly to the spacing platform of pier upper end, but it has some problems when using, in order to guarantee the protective effect who prevents falling the roof beam dog, prevent falling the roof beam dog and use steel manufacturing, its weight is heavier, and the space on the pier is less, inconvenient more strutting arrangement that uses, prevent falling the roof beam dog and only spacing not bearing, when will prevent falling the roof beam dog installation, need will prevent falling the roof beam dog and lift off ground, it is inconvenient to install.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem, a prevent roof beam dog that falls convenient to installation has been designed.

According to the technical scheme, the utility model discloses a prevent roof beam dog that falls convenient to installation, including the roof, the limiting plate is installed to roof lower surface both sides, limiting plate outside surface and roof lower surface pass through the set-square and connect, it has a plurality of connecting holes to open on the roof, be equipped with connecting stud in the connecting hole, the slide is installed at limiting plate inside surface both ends, roof below both sides are equipped with the elevator, the guide block is installed at elevator both ends, guide block one end is located the elevator, L shape stopper is installed to the slide upper end, the support column has been placed in the slide.

Furthermore, the lower end of the inner side surface of the limiting plate is provided with a damping pad.

Furthermore, a plurality of pulleys are installed on the lower surface of the lifting block.

Further, the length of the connecting stud is longer than that of the support column.

The utility model has the advantages that: the anti-falling beam stop blocks on two sides of the pier limit table are designed into a whole, the support column is placed in the slide way, the lifting block and the guide block are placed below the support column, the device is directly placed above the limit table through a hoisting device, then the anti-falling beam stop block can be moved to a position to be installed, the upper end of the anti-falling beam stop block is closer to the lower surface of the bridge, a bolt is conveniently connected to the bridge, after the installation is finished, the support column is taken down, the lifting block and the guide block can freely slide upwards, the weight of the bridge is not borne, only the limit table is limited, the installation is convenient, the device can support the lower part through a triangular plate, meanwhile, the lower end of a limit plate can be pulled through the lifting block, the guide block and the slide way, the protection effect is better, in addition, if a connecting stud is loosened and separated, the L-shaped limit block in the guide block and the slide way is used, the device can be prevented from falling, and potential safety hazards are reduced.

in the figure, 1, a top plate; 2. a limiting plate; 3. a set square; 4. connecting holes; 5. connecting a stud; 6. a slideway; 7. a lifting block; 8. a guide block; 9. an L-shaped limiting block; 10. a support pillar; 11. a vibration damping pad; 12. a pulley.

Detailed Description

The invention is described in detail below with reference to the accompanying drawings, as shown in fig. 1-3: the utility model provides a prevent roof beam dog that falls convenient to installation, including roof 1, limiting plate 2 is installed to 1 lower surface both sides of roof, 2 outside surfaces of limiting plate and 1 lower surface of roof pass through set-square 3 and connect, it has a plurality of connecting holes 4 to open on the roof 1, be equipped with connecting stud 5 in the connecting hole 4, slide 6 is installed at 2 inside surface both ends of limiting plate, 1 below both sides of roof are equipped with lifter 7, guide block 8 is installed at lifter 7 both ends, 8 one end of guide block is located lifter 7, L shape stopper 9 is installed to 6 upper ends of slide, support column 10 has been placed in the slide 6.

In order to reduce the vibration force, a vibration damping pad 11 is installed at the lower end of the inner side surface of the limiting plate 2.

To reduce the friction force when the elevator block 7 moves, a plurality of pulleys 12 are attached to the lower surface of the elevator block 7.

To prevent this anti-drop bar stop from falling off, the length of the connecting stud 5 is longer than the length of the support post 10.

The working principle of the embodiment is as follows: the method comprises the steps of placing a supporting column 10 in a slideway 6, placing a guide block 8 from the lower part of the slideway 6, placing a lifting block 7 on a beam falling prevention stop block above a limiting table on a pier through a hoisting device, enabling a top plate 1 to be close to the lower surface of a bridge, moving the device to a position where the device is installed on the bridge, reducing friction force when the device moves through a pulley 12, enabling a connecting hole 4 to concentrically correspond to a reserved hole in the bridge after moving to the installation position, installing the top plate 1 below the bridge through a connecting stud 5, using a check washer for connection between the connecting stud 5 and the reserved hole of the bridge to prevent the connecting stud 5 from being separated due to vibration, enabling the top plate 1 to move upwards after the connecting stud 5 is fastened, enabling the lifting block 7 and the guide block 8 to move towards the lower part of the slideway 6 under the action of gravity, enabling the supporting column 10 to move along with the supporting column, and enabling the upper end of the supporting column 10 to move to the lower part of an L-shaped limiting block 9, can be convenient for take it out, at this moment, elevator 7 and pulley 12 are placed in spacing bench side, damping pad 11 is located spacing bench both sides, this roof beam dog that prevents falling does not bear gravity, can support limiting plate 2 through set-square 3, effect through guide block 8 and slide 6, can pull limiting plate 2 lower extreme, its protective effect is better, after using a period, if connecting stud 5 appears becoming flexible because some reasons and makes this roof beam dog that prevents fall when whereabouts, can make elevator 7, guide block 8 moves to the top, when guide block 8 moves to L shape stopper 9 lower extreme, can support this roof beam dog that prevents falling, prevent that roof beam dog that prevents falling from dropping, reduce the potential safety hazard.
