[0024] According to the present specific embodiment, the hydraulic cylinder 102 is arranged above the base 101, the groove plate 104 is fixedly connected to the output end of the hydraulic cylinder 102, the T-shaped platform 103 is movably connected to the groove plate 104 and is located in the groove plate 104, the two ends of each damper 106 are respectively fixedly connected to the groove plate 104 and the T-shaped platform 103, the two ends of each damping spring 105 are respectively fixedly connected to the groove plate 104 and the T-shaped platform 103, and the hydraulic cylinder 102 is installed on the On the base 101, when supporting the bridge, the T-shaped platform 103 is located below the bridge, and then the hydraulic cylinder 102 is started. The output end of the hydraulic cylinder 102 controls the T-shaped platform 103 to rise until the T-shaped platform 103 is located below the bridge, so that the bridge is supported. A plurality of shock-absorbing springs 105 and dampers 106 are arranged in the groove plate 104, so that the vibration generated by the bridge construction during the process of supporting the bridge can be offset by the shock-absorbing springs 105, thereby avoiding damage to the device.

[0025] The U-shaped frame 107 is fixedly connected to the T-shaped platform 103 and is located below the T-shaped platform 103. The drive motor 111 is fixedly connected to the U-shaped frame 107 and is located inside the U-shaped frame 107. One end of the screw rod 112 is fixedly connected to the output end of the drive motor 111, and the other end of the screw rod 112 is rotatably connected to the T-shaped platform 103. The sleeve 113 is sleeved on the outside of the screw rod 112 and is threadedly matched with the screw rod 112. The T-shaped platform 103 The two limit blocks 109 are slidably connected to the T-shaped platform 103 and are respectively located in the corresponding through-slots 116. The two ends of each connecting rod 110 are rotatably connected to the sleeve 113 and the corresponding limit blocks 109. The two clamping plates 108 are respectively fixedly connected to the corresponding limit blocks 109 and are respectively located above the clamping plates 108. When constructing the bridge, the T-shaped platform 103 is first located below the bridge, and then the hydraulic cylinder 1 is started. 02, the output end of the hydraulic cylinder 102 controls the T-shaped platform 103 to rise until the T-shaped platform 103 is located below the bridge, so as to support the bridge, wherein the bridge is located between the two clamping plates 108, and then the drive motor 111 in the U-shaped frame 107 is started, and the drive motor 111 controls the screw rod 112 to rotate. Since the sleeve 113 is threadedly matched with the screw rod 112, the sleeve 113 moves on the screw rod 112, and at the same time, each end of the connecting rod 110 By performing angular rotation on the sleeve 113 and the limit block 109 respectively, the two connecting rods 110 will respectively pull the limit block 109 to move in the through groove 116 of the T-shaped platform 103. At this time, the two clamping plates 108 move relatively and move toward the outside of the bridge until the two clamping plates 108 clamp the bridge so that the bridge is fixed above the T-shaped platform 103.

At this time, the two clamps 108 move relative to each other and move toward the outside of the bridge. The slider 114 under each clamp 108 will slide in the sliding groove 117 until the two clamps 108 clamp the bridge, so that the bridge is fixed above the T-shaped platform 103. In addition, the rubber pad 115 is arranged on the outside of the clamp 108. The rubber pad 115 can increase the friction between the clamp 108 and the bridge, and can fix the bridge on the T-shaped platform 103 more stably. In the above manner, the bridge can be fixed to avoid the displacement of the bridge during use, which is beneficial to the normal construction of the bridge.

Among them, by arranging the anti-skid sleeve 205 on the hand wheel 202, the anti-skid sleeve 205 can increase the comfort and anti-skid effect when using the hand wheel 202. Through the above method, the base 101 can be fixed firmly on the ground, the base 101 is prevented from moving on the ground, and the stability of the bridge support is improved.
