Description

TECHNICAL FIELD

[0001] The utility model relates to stress tension monitoring technical field, especially in bridge prestress tension monitoring device. BACKGROUND

[0002] Concrete bridge is influenced by self gravity or bridge surface vehicle gravity, and the bridge will be bent downward to cause the lower half to be stretched or even cracked. In addition, steel strand needs to pass through the lower half of the bridge, and the lower half of the bridge will be compressed by the contraction of the prestressed steel strand, thereby generating an upward deformation to offset the deformation of the bridge downward due to gravity, so that the prestressed bridge can generate greater load. When the steel strand is produced and leaves the factory, the tension of the steel strand will be monitored.

[0003] For the related technology in the above, the inventor believes that the following defects exist: when monitoring the tension of the steel strand, the prior art mainly monitors the steel strand when it leaves the factory, which cannot monitor the steel strand at the construction site, thereby improving the limitation of the device. UTILITY MODEL CONTENT

[0004] In order to solve the above problems, the utility model provides a bridge prestress tension monitoring device.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: a bridge prestress tension monitoring device, comprising a device main body, the cross section of the device main body is arc-shaped, a monitoring piece is installed on the side wall of the device main body, a pressure sensor is installed on the monitoring piece, an L-shaped connecting piece is fixedly arranged on the side wall of the device main body, a pressing block is slidably arranged on the connecting piece, and a display screen is installed on the side wall of the device main body.

[0006] By adopting the above technical scheme, when the staff needs to monitor the tension of the steel strand, the staff needs to straighten and tighten the steel strand. Then, the staff abuts the side wall of the steel strand with the side wall of the monitoring piece. At this time, the staff needs to slide the pressing block, so that the side wall of the pressing block abuts the outer wall of the steel strand, so that the steel strand is bent. In this process, the pressure sensor displays the monitored data on the display screen, thereby completing the tension monitoring. In this process, the device main body is convenient to carry, so that the steel strand can be monitored at any time, thereby reducing the limitation of the device.

[0007] Further, a threaded rod is threadedly arranged on the side wall of the connecting piece, an adjusting disc is fixedly arranged on the side wall of the threaded rod, a rotating groove is arranged on the side wall of the pressing block close to the threaded rod, an annular groove is arranged on the inner wall of the rotating groove, the threaded rod is rotatably connected with the rotating groove, an annular block is rotatably arranged in the annular groove, and the annular block and the threaded rod are fixedly connected with each other.

[0008] By adopting the above technical scheme, when the staff needs to slide the abutting block, the staff needs to rotate the threaded rod, and then the threaded rod moves towards the monitoring piece, so that the abutting block moves towards the monitoring piece under the action of the threaded rod, thereby reducing the difficulty of the staff sliding the abutting block. In addition, when the staff rotates the threaded rod, the annular block rotates synchronously with the threaded rod under the action of the threaded rod. In this process, the annular block limits the threaded rod, thereby reducing the probability of the threaded rod and the abutting block separating from each other, and thereby improving the stability of the device.

[0009] Further, a sliding groove is formed in the side wall of the device body, the monitoring piece is in sliding connection with the sliding groove, and a fixing assembly for fixing the monitoring piece is arranged in the sliding groove.

[0010] Further, a fixing hole is formed in the upper surface of the monitoring piece, a plurality of connecting holes are arrayed in the inner top wall of the sliding groove, the fixing assembly comprises a fixing rod slidingly arranged in the fixing hole and a fixing bolt threadedly connected to the bottom surface of the device body, one end of the fixing bolt close to the fixing rod extends into the fixing hole and is in rotational connection with the fixing rod, and the fixing rod is in sliding connection with the connecting hole.

[0011] By adopting the above technical scheme, when the staff needs to monitor the steel strand with different tension, the staff needs to slide the monitoring piece, and then the horizontal distance between the two ends of the monitoring piece and the device body changes. After the adjustment is completed, the staff needs to rotate the fixing bolt, and then the fixing bolt moves upward, so that the fixing rod slides upward under the action of the fixing bolt, and then one end of the fixing rod slides into the connecting hole, thereby fixing the monitoring piece and completing the adjustment of the monitoring piece.

[0012] Further, a limiting groove is formed in the inner bottom wall of the sliding groove, a limiting block is slidingly arranged in the limiting groove, the limiting block is in mutual connection with the monitoring piece, and the fixing bolt threadedly extends through the limiting piece and extends into the fixing hole to be in rotational connection with the fixing rod.

[0013] By adopting the above technical scheme, when the staff slides the monitoring piece, the limiting block slides synchronously with the monitoring piece under the action of the monitoring piece. In this process, the fixing bolt threadedly extends through the limiting piece and extends into the fixing hole to be in rotational connection with the fixing rod, thereby reducing the probability that the fixing bolt cannot be directly opposite to the fixing rod when the staff slides the monitoring piece, and thereby improving the stability of the device.

[0014] Further, a connecting rod is fixedly arranged on the inner top wall of the connecting hole, and a connecting groove is formed in the upper surface of the fixing rod, the connecting rod and the connecting groove are matched with each other.

[0015] By adopting the technical scheme, the connecting rod limits the fixed rod, thereby reducing the probability of rotation of the fixed rod in use, and improving the stability of the device.

[0016] Further, the bottom surface of the limiting block is threadedly connected with two mutually symmetrical fixing screws, and the two fixing screws are threadedly connected with the monitoring member.

[0017] By adopting the technical scheme, the fixing screw reduces the difficulty of dismounting the limiting block by the staff, thereby reducing the difficulty of replacing the fixed rod by the staff when the fixed rod is damaged, and thereby reducing the working difficulty of the staff.

[0018] Further, the two ends of the device main body are provided with clamping grooves.

[0019] By adopting the technical scheme, the clamping groove reduces the probability of shaking of the steel strand during monitoring, thereby improving the practicability of the device.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the application, when the staff needs to monitor the tension of the steel strand, the staff needs to straighten and tighten the steel strand. Then, the staff abuts the side wall of the steel strand against the side wall of the monitoring member. At this time, the staff needs to slide the abutting block, thereby abutting the side wall of the abutting block against the outer wall of the steel strand, so that the steel strand is bent. In this process, the pressure sensor displays the monitored data on the display screen, thereby completing the tension monitoring. In this process, the device main body is convenient to carry, thereby the steel strand can be monitored at any time, thereby reducing the limitation of the device.

[0022] 2. In the application, when the staff needs to slide the abutting block, the staff needs to rotate the threaded rod, thereby moving the threaded rod towards the monitoring member, so that the abutting block moves towards the monitoring member under the action of the threaded rod, thereby reducing the difficulty of the staff in sliding the abutting block. In addition, when the staff rotates the threaded rod, the annular block rotates synchronously with the threaded rod under the action of the threaded rod. In this process, the annular block limits the threaded rod, thereby reducing the probability of mutual separation of the threaded rod and the abutting block, thereby improving the stability of the device.

[0023] 3. In the application, when the staff needs to monitor the steel strand with different tension, the staff needs to slide the monitoring member, thereby changing the horizontal distance between the two ends of the monitoring member and the device main body. After adjustment, the staff needs to rotate the fixing bolt, thereby moving the fixing bolt upwards, so that the fixed rod slides upwards under the action of the fixing bolt, thereby sliding one end of the fixed rod into the connecting hole, thereby fixing the monitoring member, thereby completing the adjustment of the monitoring member.

[0030] When the worker needs to monitor the tension of the steel strand, the worker needs to straighten and tighten the steel shear. Then, the worker abuts the side wall of the steel strand with the side wall of the monitoring piece 11. At this time, the worker needs to slide the abutting block 13, so that the side wall of the abutting block 13 abuts against the outer wall of the steel strand, so that the steel strand is bent. In this process, the pressure sensor displays the monitored data on the display screen 14, so as to complete the monitoring of the tension. In this process, the equipment main body 1 is convenient to carry, so that the steel strand can be monitored at any time, thereby reducing the limitation of the device.

[0031] The abutting block 13 is provided with a rotating groove 2 on the side wall close to the threaded rod 3, and an annular groove 21 is provided on the inner wall of the rotating groove 2. The threaded rod 3 is rotationally connected with the rotating groove 2. The threaded rod 3 is threadedly arranged on the side wall of the connecting piece 12, and the axis thereof is horizontal. The adjusting disc 31 is fixedly arranged on the side wall of the threaded rod 3, and the axis thereof coincides with the axis of the threaded rod 3. The annular block 32 is rotationally arranged in the annular groove 21, and the axis thereof coincides with the axis of the threaded rod 3. The annular block 32 is fixedly connected with the threaded rod 3.

[0032] When the staff needs to slide the abutting block 13, the staff needs to rotate the threaded rod 3, so as to move the threaded rod 3 to the direction close to the monitoring piece 11, thereby moving the abutting block 13 to the direction close to the monitoring piece 11 under the action of the threaded rod 3, thereby reducing the difficulty of the staff in sliding the abutting block 13. In addition, when the staff rotates the threaded rod 3, the annular block 32 rotates synchronously with the threaded rod 3 under the action of the threaded rod 3. In this process, the annular block 32 limits the threaded rod 3, thereby reducing the probability of mutual separation of the threaded rod 3 and the abutting block 13, thereby improving the stability of the device.

[0033] A sliding groove 22 is provided on the side wall of the equipment body 1. The monitoring piece 11 is slidably connected with the sliding groove 22. The fixing assembly 4 is arranged in the sliding groove 22 and used for fixing the monitoring piece 11.

The fixing bolt 42 extends to the fixing hole 23 from the end close to the fixing rod 41 and is rotationally connected with the fixing rod 41.

[0035] When the staff needs to monitor the steel strand with different tension, the staff needs to slide the monitoring piece 11, so as to change the horizontal distance between the two ends of the monitoring piece 11 and the equipment body 1. After the adjustment is completed, the staff needs to rotate the fixing bolt 42, so as to move the fixing bolt 42 upward, thereby sliding the fixing rod 41 upward under the action of the fixing bolt 42, and then sliding the end of the fixing rod 41 into the connecting hole 24, thereby fixing the monitoring piece 11 and completing the adjustment of the monitoring piece 11.

[0036] A limiting groove 25 is provided on the inner bottom wall of the sliding groove 22. A limiting block 5 is slidably arranged in the limiting groove 25 and connected with the monitoring piece 11. The fixing bolt 42 threadedly penetrates the limiting piece and extends to the fixing hole 23 to be rotationally connected with the fixing rod 41.

[0037] When the staff slides the monitoring piece 11, the limiting block 5 slides synchronously under the action of the monitoring piece 11, and in the process, the fixing bolt 42 is screwed through the limiting piece and extends into the fixing hole 23 to rotate the fixing rod 41, thereby reducing the probability that the fixing bolt 42 cannot be opposite to the fixing rod 41 when the staff slides the monitoring piece 11, thereby improving the stability of the device.

[0039] In order to reduce the working difficulty of the staff, the bottom surface of the limiting block 5 is screw-connected with two symmetrical fixing screws 7, and the two fixing screws 7 are screw-connected with the monitoring piece 11. The fixing screw 7 reduces the difficulty of disassembling the limiting block 5 by the staff, thereby reducing the difficulty of replacing the fixing rod 41 by the staff when the fixing rod 41 is damaged, thereby reducing the working difficulty of the staff.

[0040] In order to improve the practicability of the device, the clamping grooves 8 are arranged at both ends of the equipment main body 1. The clamping grooves 8 reduce the probability of shaking of the steel strand during monitoring, thereby improving the practicability of the device.
