On the other hand, some inspection methods are complicated to operate and time-consuming, which affects the progress of the project. In the construction of large bridges, prestress inspection needs to be carried out quickly and efficiently to ensure the quality and progress of construction.

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example 1
[0020] See also Figure 1-8The present invention provides a technical solution: a prestressed stress detection device and detection method for bridge construction, a limit machine head 1, a signal transmission interface 2 is fixedly connected to one side surface of the limit machine head 1, a jack front shell 3 is fixedly connected to one side surface of the limit machine head 1, a holding mechanism 4 is arranged on one side surface of the jack front shell 3, a signal line winding mechanism 5 is arranged on one side surface of the limit machine head 1, and an oil pump pipe winding mechanism 6 is arranged on one side surface of the holding mechanism 4; The holding mechanism 4 includes a jack housing 401, a connecting block 402, a fastening clamp 403, a support leg 404, a base 405, a rotating column 406, a side handle 407, an oil pump handle 408 and an oil pump interface 409. The jack housing 401 is fixedly connected to one side surface of the jack front shell 3, the connecting block 402 is fixedly connected to the lower surface of the jack housing 401, the fastening clamp 403 is fixedly connected to one side surface of the connecting block 402, the fastening clamp 403 is slidably connected to the support leg 404, and the support leg 404 The lower surface of the jack housing 401 is fixedly connected to a base 405, a side surface of the jack housing 401 is fixedly connected to a rotating column 406, a side surface of the rotating column 406 is slidably connected to a side handle 407, an upper surface of the jack housing 401 is fixedly connected to an oil pump handle 408, and a side surface of the oil pump handle 408 is fixedly connected to an oil pump interface 409. The jack housing 401, the connecting block 402, the fastening clamp 403, the supporting leg 404, the base 405, the rotating column 406, the side handle 407, the oil pump handle 408 and the oil pump interface 409 are connected to the jack housing 401. The pump interface 409 is set, when in use, the side handle 407 is pulled open from the inside, and due to the existence of the rotating column 406, the detection device can be lifted up as a whole when the side handle 407 is pulled, or the oil pump handle 408 is lifted to lift the detection device to achieve the transfer of the detection device. Due to the setting of multiple sets of handles, the staff can easily lift and carry the device from different angles and positions. Whether it is horizontal transportation or in complex situations such as going up and down stairs and crossing obstacles, the equipment can be easily moved. When the device is placed When the jack is positioned, the supporting leg 404 is pulled. Due to the presence of the fastening clamp 403, the supporting leg 404 can be limited so that the supporting leg 404 is firmly fixedly connected to the connecting block 402 to prevent it from falling. The cooperation between the supporting leg 404 and the base 405 enables the jack housing 401 to be firmly supported on the ground to prevent it from tilting, falling and being damaged. The ground conditions at the bridge construction site may be relatively complicated, with flat concrete floors and uneven dirt roads or gravel roads. The design of the base 405 allows the detection device to better adapt to these different terrains.
[0021] Furthermore, two groups of connecting blocks 402 are provided below the jack housing 401, and a group of fastening clamps 403 are provided on the left and right sides of the connecting block 402, respectively. A group of supporting legs 404 are provided on the left and right sides of the connecting block 402, and the base 405 is fixedly connected below the supporting legs 404. Through the arrangement of the jack housing 401, the connecting blocks 402 and the fastening clamps 403, when in use, the two groups of connecting blocks 402 are located below the jack housing 401. This distribution method can provide more uniform support, just like a rack with multiple fulcrums is more stable than a single fulcrum. They can better bear the weight of the jack and related equipment, and reduce the tilt or shaking of the device caused by excessive force on a single point. Furthermore, a side handle 407 slot is provided on the left and right sides of the jack housing 401, and the size of the slot is slightly larger than the size of the side handle 407. The rotating column 406 is fixedly connected to the slots provided on the left and right sides of the jack housing 401. Through the arrangement of the rotating column 406 and the side handle 407, when in use, the size of the slot is slightly larger than the size of the side handle 407. This design detail allows the side handle 407 to rotate flexibly in the slot. When the handle is not needed, the handle can be stored in the slot to prevent the handle from protruding outside and affecting other operations of the device or being damaged during transportation. When the handle is needed, it can be easily turned out, thereby improving the convenience of use of the device.
[0022] Furthermore, the side handle 407 can rotate freely therein through the rotating column 406 and the slot hole setting, and two groups of oil pump interfaces 409 are set on the side surface of the oil pump handle 408. Through the setting of the rotating column 406 and the side handle 407, when in use, the freely rotating handle can be stored when not in use, and will not take up extra space, making the placement of the detection device at the construction site or in the storage environment more flexible.
[0023] Furthermore, the signal line winding mechanism 5 includes a front rotating bead 501, a front rotating barrel 502, a front fixing block 503 and a front latch 504. The front rotating bead 501 is slidably connected to one side surface of the position limiting machine head 1, the front rotating bead 501 is slidably connected to the front rotating barrel 502, the front rotating barrel 502 is slidably connected to the front fixing block 503, and the front rotating barrel 502 is fixedly connected to the front latch 504. When in use, the user can directly wind the signal line around the front rotating barrel 502. Due to the presence of the front latch 504, the front rotating barrel 502 can be effectively prevented from rolling randomly when winding the signal line, so that the signal line is not easily wound around it. The winding device can neatly store these cables to avoid the cables being distributed in a disorderly manner. This not only makes the detection site tidier, but also prevents the cables from being entangled and knotted with each other, and reduces the detection interruption caused by cable damage. When it is necessary to release the line, the tail end of the signal line can be directly pulled out. Since the front rotating bead 501 and the front rotating barrel 502 cooperate with each other, the signal line can be easily pulled out, which facilitates the use of the signal line.
[0024] Furthermore, there are multiple groups of front rotating beads 501 symmetrically arranged along the central axis of the limiting head 1. Due to the arrangement of the front rotating beads 501, the front rotating barrel 502 can rotate freely along the central axis of the limiting head 1. Through the arrangement of the front rotating beads 501, when in use, the rolling friction mode of the front rotating beads 501 can greatly reduce the friction between the front rotating barrel 502 and the limiting head 1 compared to other friction modes (such as sliding friction). When the friction between the components is reduced, the wear generated during the rotation process will also be reduced accordingly, which is beneficial to extending the service life of the equipment.
[0025] Furthermore, the front fixing block 503 is fixedly connected to the limiting machine head 1, and plays a clamping and limiting role on the front rotating barrel 502. Multiple groups of front latches 504 are symmetrically arranged on the central axis of the front rotating barrel 502, and the front latches 504 can limit the rotation of the front rotating barrel 502. Through the setting of the front fixing block 503, when in use, the front rotating barrel 502 can be effectively prevented from falling off, thereby avoiding possible damage to the equipment itself.
[0026] Furthermore, the oil pump pipe winding mechanism 6 includes a rear rotating bead 601, a rear rotating barrel 602, a rear fixing block 603 and a rear latch 604. The rear rotating bead 601 is slidably connected to the surface of one side of the jack housing 401, the rear rotating barrel 602 is slidably connected to the surface of one side of the rear rotating bead 601, the rear rotating barrel 602 is slidably connected to the surface of one side of the rear rotating barrel 602, the rear fixing block 603 is slidably connected to the surface of one side of the rear rotating barrel 602, and the rear latch 604 is fixedly connected to the surface of one side of the rear rotating barrel 602. By setting the rear rotating bead 601, the rear rotating barrel 602, the rear fixing block 603 and the rear latch 604, when in use, the user can directly wind the oil pump pipe around the rear rotating barrel 602 At the top, due to the presence of the rear latch 604, the rear rotary barrel 602 can be effectively prevented from rolling randomly when the oil pump tube is wound, so that the oil pump tube is not easily wound on the top, and the winding device can neatly store these oil pump tubes to avoid the disorderly distribution of the oil pump tubes, which not only makes the detection site more tidy, but also prevents the oil pump tubes from being entangled and knotted with each other, and reduces the interruption of detection caused by damage to the oil pump tube. When the oil pump tube needs to be released, the tail end of the oil pump tube can be directly pulled out, and since the rear rotary bead 601 and the rear rotary barrel 602 cooperate with each other, the oil pump tube can be easily pulled out, which facilitates the use of the oil pump tube.
[0027] Furthermore, the protection mechanism 7 includes a winding thread 701, a fixed shell 702, a hinge 703, a movable shell 704 and a combined magnet 705. A winding thread 701 is provided on one side surface of the oil pump tube winding mechanism 6, a fixed shell 702 is fixedly connected to one side surface of the oil pump tube winding mechanism 6, a hinge 703 is fixedly connected to one side surface of the fixed shell 702, a movable shell 704 is fixedly connected to one side surface of the hinge 703, and a combined magnet 705 is fixedly connected to one side surface of the movable shell 704. Example 2
[0028] A prestress detection device and detection method for bridge construction, using the prestress detection device for bridge construction in embodiment 1, further comprising the following steps: Step 1: Pull the side handle 407 from the inside, and when the side handle 407 and the oil pump handle 408 are pulled, the entire detection device can be lifted and the detection device can be transferred; Step 2: After the detection device is transferred to the designated position, pull the support leg 404, tighten the clamp 403 to limit the support leg 404, so that it is fixedly connected with the connecting block 402, so that the jack housing 401 is firmly supported on the ground to prevent tilting, falling and damage; Step 3: When in use, insert the steel bar into the limit machine head 1, connect the signal line and the oil pump pipe and start the machine to detect the prestress of the steel bar; Step 4: After the test is completed, the signal line is wound around the front rotating barrel 502, and the oil pump pipe is wound around the rear rotating barrel 602. The front latch 504 and the rear latch 604 effectively prevent the signal line and the oil pump pipe from rolling on the front rotating barrel 502 and the rear rotating barrel 602. After winding, the oil pump pipe can be prevented from being distributed in a disorderly manner. Step 5: After the winding is completed, the movable shell 704 is rotated, and the fixed shell 702 can be combined with the movable shell 704 through the hinge 703, and the magnet 705 is combined to make the two fit tightly, so as to protect the signal line and the oil pump pipe.
[0029] With the above structure, the working principle of the present invention is as follows: the prestressed steel detection device and detection method for bridge construction, through the setting of the holding mechanism 4, when the detection device needs to be transferred, the side handle 407 is pulled open from the inside, and due to the existence of the rotating column 406, the detection device can be lifted up as a whole when the side handle 407 is pulled, or the oil pump handle 408 is lifted to lift the detection device to achieve the transfer of the detection device. Due to the setting of multiple sets of handles, the staff can easily lift and carry the device from different angles and positions, and the equipment can be easily moved in complex situations such as horizontal transportation or going up and down stairs and crossing obstacles. When placing the device, pull the support leg 404. Due to the presence of the fastening clamp 403, the support leg 404 can be limited so that the support leg 404 is firmly fixedly connected to the connecting block 402 to prevent it from falling. The cooperation between the support leg 404 and the base 405 allows the jack housing 401 to be firmly supported on the ground to prevent it from tilting, falling and being damaged. The ground conditions at the bridge construction site may be more complicated, with flat concrete floors and uneven dirt roads or gravel roads. The design of the base 405 allows the detection device to better adapt to these different terrains. Through the setting of the signal line winding mechanism 5, when storing the signal line, the user can directly wrap the signal line around The front latch 504 above the front rotating barrel 502 can effectively prevent the front rotating barrel 502 from rolling randomly when winding the signal line, so that the signal line is not easily wound on it. The winding device can neatly store these cables to avoid the cables being distributed in a disorderly manner. This not only makes the detection site more tidy, but also prevents the cables from being entangled and knotted with each other, and reduces the detection interruption caused by cable damage. When it is necessary to release the line, the tail end of the signal line can be directly pulled out. Since the front rotating bead 501 and the front rotating barrel 502 cooperate with each other, the signal line can be easily pulled out, which facilitates the use of the signal line. By setting the oil pump tube winding mechanism 6, the oil pump tube can be stored. When the oil pump tube is in the working state, the user can directly wind the oil pump tube around the rear rotary barrel 602. Due to the presence of the rear latch 604, the rear rotary barrel 602 can be effectively prevented from rolling randomly when the oil pump tube is wound, so that the oil pump tube is not easily wound around. The winding device can neatly store these oil pump tubes to avoid the disorderly distribution of the oil pump tubes, which not only makes the detection site more tidy, but also prevents the oil pump tubes from being entangled and knotted with each other, and reduces the interruption of detection caused by damage to the oil pump tube. When the oil pump tube needs to be released, the tail end of the oil pump tube can be directly pulled out. Since the rear rotating bead 601 and the rear rotary barrel 602 cooperate with each other, the oil pump tube can be easily pulled out, which is convenient for the use of the oil pump tube.
