Detailed Description
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of a construction apparatus for disassembling and assembling a railway bridge anti-vibration drop block according to the present invention, and fig. 2 is a schematic view illustrating an exemplary anti-vibration drop block suitable for supporting the construction apparatus according to the present invention.
As shown in fig. 1, the construction apparatus includes a base, two first column members 1, two second column members 1 ', a first anti-shake drop-off stop backup plate member 3, and a second anti-shake drop-off stop backup plate member 3'.
The base is in a rectangular frame structure and comprises two opposite first frame members 4 and two opposite second frame members 6, and reinforcing ribs 5 which are diagonally crossed are arranged in the rectangular frame. Four wheel members 7 are symmetrically provided under the base, and the four wheel members 7 are connected to the base two by two symmetrically and can drive the construction apparatus to move in the length direction of the first frame member 4.
The construction device is further provided with a hand member 8, which hand member 8 is fixedly connected to one of the second frame members 6.
Two first upright members 1 are symmetrically and perpendicularly connected to one of the first side frame members 4 for collectively supporting and positioning the first anti-rattle drop stop support plate member 3. Two second upright members 1 'are symmetrically and perpendicularly connected to the other first upright member 4 for supporting and positioning the second anti-shake drop-off block support plate member 3'. The first and second anti-rattle drop beam stop support plate members 3 and 3' are configured to support the anti-rattle drop beam stop 9 from below the anti-rattle drop beam stop 9 to be removed or installed.
The distance between the two first upright post members 1 or the distance between the two second upright post members 1 'is at least larger than the width of the first supporting vertical plate 902 or the second supporting vertical plate 903, and more preferably larger than the width of the upper end surface 901 of the shockproof beam falling stopper 9, so that the shockproof beam falling stopper 9 can be smoothly placed on the first shockproof beam falling stopper supporting plate member 3 and the second shockproof beam falling stopper supporting plate member 3' and reliably supported, and the gravity center of the shockproof beam falling stopper 9 is ensured to be at a lower position in the process of transporting the shockproof beam falling stopper 9. Furthermore, the spacing between the first and second anti-rattle drop stop backer plate members 3, 3' is the same as the distance between the first and second support risers 902, 903 of the anti-rattle drop stop 9.
The maximum height of the construction device is set to be 4cm or more smaller than the distance between the pier top of a pier of a railway bridge to be constructed and the bottom of the bridge, and the minimum height is larger than the difference between the distance between the pier top and the bottom of the bridge and the maximum height of the shockproof beam falling stop block 9. When the whole height of the construction device is within the range, the anti-vibration beam falling stop block 9 can be well ensured to be lifted to the position near the beam bottom, and the situation that the anti-vibration beam falling stop block 9 cannot enter the space between the pier top of the pier and the beam bottom of the bridge due to the fact that the space between the construction device and the beam bottom of the bridge is too small due to the fact that the construction device is too high is avoided.
The first upright post member 1 and the second upright post member 1' are long bolt members, the first shockproof beam falling stop support plate member 3 is sleeved on the first upright post member 1 through two symmetrical through holes on the first upright post member, and the first upright post member 1 is further sleeved with an upper nut 2 and a lower nut 2 which are respectively positioned on the upper side and the lower side of the first shockproof beam falling stop support plate member 3 to limit the position of the first shockproof beam falling stop support plate member 3.
The second shockproof beam falling stop supporting plate component 3 'is sleeved on the second upright post component 1' through two symmetrical through holes on the second shockproof beam falling stop supporting plate component, and the position of the second shockproof beam falling stop supporting plate component 3 'is positioned by the upper nut 2 and the lower nut 2 sleeved on the second upright post component 1'.
The nut 2 and the first shockproof beam falling stop block support plate component 3 and the second shockproof beam falling stop block support plate component 3' respectively form two groups of structures capable of moving up and down, and the structures capable of moving up and down can enable the shockproof beam falling stop block 9 to freely lift in the height range from the pier top to the beam bottom.
The first and second anti-rattle drop beam stop support plate members 3, 3' are angle steel members, respectively. It is preferred to construct the first anti-rattle drop stop support panel member 3 to be located higher than the second anti-rattle drop stop support panel member 3 'or the first anti-rattle drop stop support panel member 3 to be located flush with the second anti-rattle drop stop support panel member 3'. When the beam stopper 9 that will take precautions against earthquakes is placed on the construction equipment, the bottom surfaces of the first supporting riser 902 and the second supporting riser 903 of the beam stopper 9 that takes precautions against earthquakes are located in the second beam stopper backup pad 3' that takes precautions against earthquakes and the first beam stopper backup pad 3 that takes precautions against earthquakes, respectively.
One side of the first anti-vibration falling beam block support plate component 3 is kept horizontal, and the other side is vertically upward. One side of the second anti-shake falling beam block support plate member 3' is kept horizontal, and the other side is vertically downward. In the process of transporting the shockproof beam stop block 9 on the pier top of the pier, the first shockproof beam stop block support plate component 3 is positioned outside the construction device relative to the pier, and the angle steel component can increase the contact area between the shockproof beam stop block 9 and the first shockproof beam stop block support plate component 3 and between the shockproof beam stop block support plate component 3 'and the second shockproof beam stop block support plate component 3', so that the operation process is more stable. Meanwhile, the vertical upward side of the first shockproof beam falling stop supporting plate component 3 can limit the shockproof beam falling stop 9 from generating excessive displacement, so that the danger caused by the sliding of the shockproof beam falling stop 9 is effectively prevented. In addition, one side of the second anti-vibration drop beam stopper support plate member 3' is horizontal and the other side is vertically downward, so that the construction does not cause an obstruction when the anti-vibration drop beam stopper 9 is moved to or transferred from the construction apparatus, thereby making the operation smoother and effectively improving the construction efficiency.
In addition, the relative position between the first and second anti-seismic falling beam stop support plate members 3 and 3' is set to ensure that the upper end face of the anti-seismic falling beam stop 9 is kept horizontal, so that the center of gravity of the anti-seismic falling beam stop 9 and the construction device is kept stable, the possibility that the anti-seismic falling beam stop 9 slides down is reduced, and the construction efficiency is improved.
A method for mounting or dismounting the bridge girder drop-preventing stoppers 9 by using the above construction apparatus will be described below.
The process of mounting the bridge shockproof beam falling stop block 9 by using the construction device is as follows:
