The top of 8 is fixedly connected with a protruding rod 10 that is compatible with the limit hole 9; since the pusher usually has a horizontal drive and a vertical drive, and its volume is usually large, it will take up more space when it is transported. However, the existing steel box girder 1 pushing device cannot be adjusted, and thus the occupied space cannot be reduced, and it is not convenient for transportation. During work, the lifting plate 8 is driven by the screw rod 13 to move down to the bottom of the box body 2, so that the protruding rod 10 Detach from the limit hole 9 on the rotating plate 5, so that the rotating plate 5, the jack 6 and the temporary pier 7 can be rotated downwards and stored inside the box body 2, so that the occupied space can be reduced, and it is convenient to transport and move. Stronger, the front and back of the box body 2 and the both sides of the lifting plate 8 are provided with openings, because the lifting plate 8, the jack 6 and the temporary pier 7 need certain activities when they are rotated downward and stored inside the box body 2. range, through the setting of the openings, it can be avoided from being blocked, so as to facilitate the storage and processing of the temporary pier 7, which has strong practicability.

One end is fixedly connected, and the bottom between the two walls of the box body 2 and the front and back of the screw rod 11 are fixedly connected with a limit rod 12; during work, the moving direction of the movable plate 4 can be limited by the limit rod 12 At the same time, the support force to the moving plate 4 can be enhanced through the setting of the two limit rods 12, thereby improving the stability of the moving plate 4.
两个所述移动板4一侧的中部通过螺纹孔与丝杆11的外表面螺纹连接,所述移动板4一侧的正面和背部均通过滑孔与限位杆12的外表面滑动连接;工作时,由于丝杆11在转动时两个移动板4为同步并且同向移动,进而两个移动板4之间始终会保持相同的距离。The middle parts on one side of the two moving plates 4 are threadedly connected to the outer surface of the screw mandrel 11 through threaded holes, and the front and back sides on one side of the moving plates 4 are slidably connected to the outer surface of the stop rod 12 through sliding holes; During operation, since the two moving plates 4 are synchronous and move in the same direction when the screw rod 11 rotates, the same distance will always be maintained between the two moving plates 4 .
所述调节机构包括螺杆13,所述螺杆13的底端通过轴承与箱体2内腔底部的正面转动连接,所述箱体2内腔底部的背部固定连接有竖杆14,所述升降板8底部的正面通过螺纹孔与螺杆13的外表面螺纹连接,所述升降板8底部的背部通过滑孔与竖杆14的外表面滑动连接;工作时,螺杆13的顶端固定连接有拧手,通过拧手方便施工人员操作螺杆13转动,较为方便使用。The adjustment mechanism includes a screw 13, the bottom of the screw 13 is rotationally connected with the front of the bottom of the inner cavity of the box body 2 through a bearing, the back of the inner cavity bottom of the box body 2 is fixedly connected with a vertical rod 14, and the lifting plate The front of the bottom of 8 is threadedly connected with the outer surface of the screw rod 13 through a threaded hole, and the back of the bottom of the lifting plate 8 is slidably connected with the outer surface of the vertical rod 14 through a slide hole; during work, the top of the screw rod 13 is fixedly connected with a screwdriver It is convenient for construction personnel to operate the screw rod 13 to rotate by twisting hands, which is more convenient to use.
所述限位孔9和凸杆10的数量均设置有若干个;工作时,通过多个限位孔9和凸杆10的设置可以增强装置的稳定性。The number of the limiting holes 9 and the protruding rods 10 are all provided with several; when working, the stability of the device can be enhanced by the arrangement of a plurality of limiting holes 9 and protruding rods 10 .
所述临时墩7的顶部固定连接有防滑垫15,所述防滑垫15的顶部与钢箱梁1的底部相贴合;工作时,通过防滑垫15可以增加临时墩7对钢箱梁1顶推时的摩擦力,避免临时墩7在对钢箱梁1进行顶推时出现打滑的情况,进而可以使得顶推施工实施地更加顺畅。The top of the temporary pier 7 is fixedly connected with an anti-slip pad 15, and the top of the anti-slip pad 15 fits the bottom of the steel box girder 1; during work, the temporary pier 7 can be added to the top of the steel box girder 1 through the anti-slip pad 15. The frictional force during pushing can prevent the temporary pier 7 from slipping when pushing the steel box girder 1, thereby making the pushing construction more smooth.
工作原理,由于顶推装置通常具有横向驱动以及竖向驱动,进而其通常体积较大,在对其运输时,会较为占用空间,但是现有的钢箱梁1顶推装置无法进行调节,进而无法缩小占用空间,不便于进行运输,由于桥梁施工需要使用顶推装置,进而在钢箱梁1进行顶推施工前,需要将顶推装置运输至施工场地,当需要对顶推装置进行运输时,首先转动拧手带动螺杆13逆时针转动,进而带动升降杆向下移动,直至其移动至箱体2最底部的位置,此时,升降板8上的凸杆10已经完全脱离限位孔9并距离转动板5较远,此时将转动板5、千斤顶6和临时墩7均向下转动,使的千斤顶6和临时墩7均进入箱体2内部,从而缩小该装置的占用空间,方便进行运输,当该装置运输至施工场地安装后,需要进行顶推施工时,将转动板5向上转动,使得千斤顶6和临时墩7均向上转动至原位,然后顺时针转动拧手带动螺杆13转动,使得升降板8向上移动,直至升降板8移动至螺杆13最高处,此时,升降板8上的凸杆10会完全进入限位孔9中,从而起到支撑转动板5以及限位转动板5的作用,然后启动千斤顶6带动临时墩7向上移动,直至防滑垫15与钢箱梁1完全贴紧,再启动电机3带动丝杆11顺时针转动,从而推动钢箱梁1向右侧移动,直至移动板4移动至与箱体2右壁接触的位置,控制千斤顶6带动临时墩7向下移动远离钢箱梁1,再控制电机3逆时针转动带动丝杆11转动,使得移动板4和临时墩7向左移动,直至左侧的移动板4移动至与箱体2左壁接触使,按照以上操作重复进行顶推操作即可。Working principle, because the jacking device usually has a horizontal drive and a vertical drive, and its volume is usually large, it will take up more space when it is transported, but the existing steel box girder 1 jacking device cannot be adjusted, and thus The occupied space cannot be reduced, and it is not convenient for transportation. Because the bridge construction needs to use the jacking device, and before the steel box girder 1 is pushed, the jacking device needs to be transported to the construction site. When the jacking device needs to be transported , first turn the screw to drive the screw 13 to rotate counterclockwise, and then drive the lifting rod to move downward until it moves to the bottom position of the box body 2. At this time, the protruding rod 10 on the lifting plate 8 has completely disengaged from the limit hole 9 And apart from rotating plate 5 far away, now rotating plate 5, jack 6 and temporary pier 7 are all rotated downwards, and jack 6 and temporary pier 7 of making all enter casing 2 inside, thereby reduce the occupied space of this device, convenient For transportation, when the device is transported to the construction site for installation, when the pushing construction needs to be carried out, the rotating plate 5 is turned upward so that the jack 6 and the temporary pier 7 are turned upward to the original position, and then the screwdriver is turned clockwise to drive the screw 13 Rotate to make the lifting plate 8 move upward until the lifting plate 8 moves to the highest point of the screw rod 13. At this time, the protruding rod 10 on the lifting plate 8 will completely enter the limit hole 9, thereby supporting the rotating plate 5 and the position limit. Turn the function of the plate 5, then start the jack 6 to drive the temporary pier 7 to move upward until the anti-skid pad 15 is completely attached to the steel box girder 1, and then start the motor 3 to drive the screw 11 to rotate clockwise, thereby pushing the steel box girder 1 to the right Move sideways until the moving plate 4 moves to the position in contact with the right wall of the box body 2, control the jack 6 to drive the temporary pier 7 to move down and away from the steel box girder 1, and then control the motor 3 to rotate counterclockwise to drive the screw 11 to rotate, so that the moving The plate 4 and the temporary pier 7 move to the left until the moving plate 4 on the left side is in contact with the left wall of the box body 2, and the pushing operation can be repeated according to the above operation.
