Description

Technical Field

[0001] The utility model belongs to the technical field related to bridge rotation construction, in particular to a vertical force measuring component for bridge rotation construction. Background Art

[0002] Bridge rotation construction is a specialized construction with high technical content and high construction risk. The safety and accuracy of the rotation process of the rotating bridge have always been the focus of attention in the rotation process. The state monitoring and control adjustment during the bridge rotation process can predict whether the rotated beam is in a safe state and control the bridge rotation state according to needs, thereby improving the risk prevention ability during the bridge rotation. The vertical load of the spherical joint, the vertical rotation angle state of the beam and the stress state of the support leg during the bridge rotation process can reflect the safety state of the bridge during the rotation process. The change in the vertical inclination angle of the upper beam can cause the distribution change of the vertical load of the spherical joint. The change in the vertical load of the spherical joint can reflect the equilibrium state of the beam; the stress state of the support leg can also reflect the change in the state of the upper beam. When the upper beam tilts more, the support leg stress will also increase. The tilt state of the upper beam is analyzed by the change in the support leg stress, but it still has the following disadvantages in actual use:

[0003] During the bridge rotation construction process, vertical force sensors are needed to detect the pressure changes in various directions on the supporting structure at the bottom of the bridge rotation. After the rotation construction is completed, the vertical force sensors are usually left in the supporting structure to detect the pressure of the bridge. However, they will be damaged during long-term use. After damage, it is troublesome to replace a single vertical force sensor due to the high pressure of the rotating bridge.

[0004] During the rotation construction, in order to better maintain the supporting effect of the bridge rotation, it is necessary to use support legs to assist in support. After the construction is completed, the support legs need to be removed and replaced with immovable support seats with better support effects. During replacement, the support legs are not convenient to replace due to the high pressure they are subjected to. Utility Model Content

The top of the threaded rod is inserted into the top of the support box, and the threaded rod extends out of the top of the support box. Each threaded rod on the top of the support box is threadedly connected to a nut on the peripheral side. When working, the corresponding structure is mounted on it through the bridge body connecting plate, and the bridge body connecting plate is supported thereon by the support platform, and the pressure on each position of the fixed column is detected by the pressure detection component to determine whether the pressure at different positions on the bridge body connecting plate changes, and whether the rotating bridge is tilted. The support leg and the support box cooperate to provide auxiliary support for the bridge body connecting plate to assist in the support of the rotating bridge during rotation.

[0008] Furthermore, the bottom of the bridge connecting plate on both sides of the fixing column is provided with a socket, and the inner center of the curved panel is provided with a pin hole, and the fixing column is movably connected to the support leg through the socket and movably connected to the pin shaft through the pin hole.

[0009] Furthermore, an arc-shaped opening is opened in the center of the top of the support platform, and the arc-shaped panel is movably connected in the arc-shaped opening. A pin is fixed in the center of the bottom of the arc-shaped opening, and the pin is inserted into the pin hole. The pin is movably connected in the pin hole through the pin in the arc-shaped opening, so that the support platform and the fixed column are restricted together.

[0010] Furthermore, the pressure detection assembly also includes a rolling ball and a pulling frame. The rolling ball is movably connected to the upper part of the inner wall of the fixed sleeve. The top of the vertical force sensor abuts against the rolling ball, and the top of the rolling ball abuts against the fixed column.

During operation, when a single pressure detection component is damaged, the fixing sleeve can be driven to move and be removed by pulling the pulling frame, and the new fixing sleeve can be reinserted into place along the gap groove to complete the replacement and maintenance, making the maintenance and replacement of the vertical force sensors more convenient.

[0015] The utility model solves the problem of inconvenience in removing the supporting legs after the rotation construction of the bridge is completed by arranging a bridge connecting plate, supporting legs and a supporting box.

After the nut is unscrewed from the threaded rod, the supporting legs fall back into the supporting box, the supporting legs and the bridge connecting plate are separated, and new supporting legs are reinstalled to complete the work. After the rotation construction of the bridge is completed, it is more convenient to remove the supporting legs. BRIEF DESCRIPTION OF THE DRAWINGS

A fixed column 102 is fixed to the bottom center of the bridge connecting plate 1. The top of the bridge connecting plate 1 is connected to the bottom center of the rotating bridge and is supported on the support platform 2 through the fixed column 102 to provide support for the bridge connecting plate 1. The bottom end of the fixed column 102 is fixed with an arc panel 103. After the arc panel 103 is pressed on the support platform 2, the support platform 2 is supported well during work. , a support platform 2 is provided at the bottom end of the fixed column 102, and a gap groove 201 is opened in a ring array at the top edge of the support platform 2. The support platform 2 connects the detection component movably therein through the gap groove 201. A pressure detection component 3 is movably connected in the gap groove 201. The pressure detection component 3 includes a fixed sleeve 301 and a vertical force sensor 302. A vertical force sensor 302 is fixed to the lower part of the inner wall of the fixed sleeve 301. The pressure detection component 3 measures the pressure of the bridge connecting plate 1 pressed to different positions on the fixed column 102 through the vertical force sensor 302. The vertical force sensor 302 is used to measure the vertical force of the fixed sleeve 301. The bottom of the bridge connecting plate 1 on both sides of the fixed column 102 is movably connected with the support leg 4, and the bridge connecting plate 1 is assisted by the support leg 4 to support the support box 5. The lower part of the peripheral side of the support leg 4 is movably connected to the support box 5. The support leg 4 is supported on the external rolling component through the support box 5 to cooperate with the rotation of the swivel bridge. The lower edge of the peripheral side of the support leg 4 is fixed with a mounting plate 402, and the top of the mounting plate 402 is fixed with a threaded rod 404 in a ring array. The top end of the threaded rod 404 is inserted into the top of the support box 5, and the threaded rod 404 extends out of the top of the support box 5. Each threaded rod 404 on the top of the support box 5 is threadedly connected to a nut 405 on the side. During operation, when the limiting support leg 4 is installed, the support leg 4 is pushed upward, and after entering the bridge body connecting plate 1 through the support leg 4, the threaded rod 404 is inserted into the top of the support box 5 and extended out, and the nut 405 is screwed to the side of the threaded rod 404 and gradually rotated to tighten, so that when working, the support leg 4 can provide a certain support to the bridge body connecting plate 1.

[0028] Specifically, a socket 101 is provided at the bottom of the bridge connecting plate 1 on both sides of the fixed column 102, and a pin hole 104 is provided through the center of the inner part of the curved panel 103.

The pulling frame 304 is fixed to the circumferential side of the fixed sleeve 301. The pressure detection component 3 abuts against the fixed column 102 through the rolling ball 303, so that the pressure on the fixed column 102 is transmitted to the vertical force sensor 302 to detect the pressure. After the rotation of the bridge is completed, the fixing sleeve 301 is pulled out of the gap groove 201 on the support platform 2 by pulling the pulling frame 304.

[0031] The operation process of this embodiment is as follows: when working, align the pin hole 104 on the curved panel 103 at the bottom end of the fixed column 102 at the bottom of the bridge body connecting plate 1 with the pin shaft 203 in the curved opening 202, insert the pin shaft 203 into the pin hole 104, and then make the curved panel 103 enter the curved opening 202 on the support platform 2. At this time, each rolling ball 303 in the gap groove 201 abuts against the bottom end of the fixed column 102. During operation, the vertical force sensors 302 in various directions measure the vertical force of the fixed column 102 in various directions. When the forces in various directions are unbalanced, it can be detected quickly to prevent the skewing of the swivel bridge during rotation and cause safety accidents. After the rotation construction is completed, the pressure detection component 3 can be left in the gap groove 201 of the support platform 2 to detect the balance of the swivel bridge. During operation, when a single pressure detection component 3 is damaged, the pulling frame 304 can be pulled to drive the fixing sleeve 301 to be taken out, and the new fixing sleeve 301 can be reinserted into place along the gap groove 201 to complete the replacement and maintenance, which is convenient for maintenance.
