Description
Technical Field
[0001] The invention relates to the technical field of shaft detection, in particular to an integral movable steel mould for detecting a shaft section. Background Art
[0002] A vertical shaft is a structure that vertically penetrates an underground cave or mine. It is often used in mining, construction engineering, geological exploration and other fields. Vertical shafts come in various forms. They can be vertical shaft openings in underground mines or vertical passages for installing elevators or exhaust systems in construction projects.
[0003] As a common construction project, the shape and size of the shaft are affected by many factors such as geological conditions, construction methods and equipment accuracy, so it may be irregular and asymmetric. Traditional steel formwork only supports the pouring of concrete, and it is difficult to detect the irregular aperture in the shaft. Therefore, when the formwork is only placed according to the predetermined anchor point, it is easy to cause errors in the distance between the periphery of the formwork and the inner wall of the shaft, which may cause inconsistent concrete pouring thickness around the steel formwork, and thus have an adverse effect on the balance and stability of the final support effect.

After the contact rod contacts the contact piece in the socket, an electrical signal will be transmitted to the inside of the integrated box, and then the collected data will be synchronously transmitted to the receiving device of the staff, so as to obtain accurate shaft section deformation data in time, and then make appropriate adjustments to the area that exceeds the deformation threshold, so that the subsequent pouring work has a good balance and improves the stability of the final support effect.
[0015] 2. In the present invention, the lifting process is also accompanied by the start-up of the air pump. The air pump will send gas into the air pipe and blow it to the multiple inclined blocks at the bottom of the rotating ring, causing the rotating ring to rotate, thereby driving the connecting tube and the magnet to rotate synchronously. In this state, the two contact rods on the outer wall of the mold body will rotate accordingly, so that while the mold body is lifted upward, the contact area of the baffle plate and the contact area of the inner wall of the shaft are greatly increased, thereby further increasing the detection range of the deformation area and making the measured data more comprehensive.
[0016] 3. In the present invention, during the rotation of the two contact rods, if a deformation area is detected, the resistance force will drive the end of the conical block to detach from the interior of the connecting tube and drive the contact rod to be inserted into the corresponding socket. At this time, the contact rod and the resistance plate will stop rotating, but will still be lifted with the mold body. On the basis of accurately positioning the deformation area, the degree of deformation is also accurately measured, providing more accurate detection data for the staff. At the same time, the other contact rod is still rotating with the rotating ring, and the flatness of other parts of the inner wall of the shaft is detected to ensure that the deformation state and data in the shaft are fully collected, so that the staff can adjust the deformation area in time to make the subsequent pouring and support work more stable and reliable.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] See also Figure 1-10 The present invention provides a technical solution: an integral movable steel mold for detecting a shaft section, comprising: Embodiment 1, The mold body 1 has a cavity 2 disposed inside the mold body 1, and the outer wall of the cavity 2 is fixedly connected to the inner wall of the mold body 1. The wall of the mold body 1 is provided with a plurality of jacks 3, and the plurality of jacks 3 are symmetrically distributed at equal intervals, and the jacks 3 have two rows distributed in high and low positions. The mold body 1 is provided with two measuring pieces 4 for measuring the deformation depth of the shaft, and the two measuring pieces 4 correspond to the two rows of jacks 3 respectively. The measuring piece 4 includes a contact rod 401, a connecting rod 402 and a baffle plate 403. The end of the contact rod 401 is shaped in an arc surface, and this shape makes it easier for the contact rod 401 to be inserted into the interior of the jack 3. The baffle plate 403 has a symmetrical arc surface, and this shape makes it easier for the end of the baffle plate to be in contact with the shaft when the overall steel mold is lifted upward. To prevent jamming, a shaft 404 is provided between the connecting rod 402 and the contact rod 401, the shaft 404 is fixedly connected to the connecting rod 402, the contact rod 401 is rotatably connected to the shaft 404, a contact piece 405 is provided inside the socket 3 and is fixedly connected thereto, an integrated box 406 is provided on the outer wall of the mold body 1 and is fixedly connected thereto, the integrated box 406, the contact piece 405 and the contact rod 401 are electrically connected; the contact rod 401 enters the socket 3 and contacts the inner wall of the contact piece 405, at which time the integrated box 406 receives an electrical signal, and then transmits the measurement data to the receiving device of the staff on the ground to obtain the deformation depth of the local area in the shaft.
[0021] Furthermore, a connecting plate 5 is provided on the outer wall of the contact rod 401, and the contact rod 401 is located inside the connecting plate 5 and fixedly connected thereto, an air bag 6 is provided at the end of the connecting plate 5 and fixedly connected thereto, and the end of the air bag 6 slides freely on the outer wall of the mold body 1, and the air bag 6 has the elasticity of automatic recovery, and an insertion rod 11 is provided inside the contact rod 401, and the insertion rod 11 is simultaneously located inside the shaft body 404, the connecting rod 402 and the contact rod 401, and a spring 2 12 is provided outside the insertion rod 11, and the two ends of the spring 2 12 are respectively fixedly connected to the insertion rod 11 and the contact rod 401, and the contact rod 401 slides freely inside the shaft body 404, the connecting rod 402 and the contact rod 401; the staff can pull the insertion rod 11 out of the connecting rod 402 and the contact rod 401 without using a steel mold for inspection, and then rotate the connecting rod 402 and the baffle plate 403 downward ninety degrees so that the two are retracted into the inner side of the outer wall of the mold body 1 without hindering the normal pouring of concrete.
[0022] The mold body 1 is also provided with a detection unit 7 inside, and the detection unit 7 cooperates with the two measuring pieces 4 to capture the cross-sectional deformation position of different areas in the shaft, and at the same time measure the deformation depth of this area. The detection unit 7 includes an air pump 701, and the outer wall of the air pump 701 is fixedly connected to the inner wall of the mold body 1 through a connecting frame. An air pipe 702 is provided at the end of the air pump 701 and is connected to the inner wall of the mold body 1. A rotating ring 703 is provided at the end of the air pipe 702. The rotating ring 703 is located inside the mold body 1 and is rotatably connected thereto. A plurality of annular covers 15 are provided at the bottom of the rotating ring 703. There are two annular covers 15, which can be combined into a circular ring. When the steel mold is normally cast, they can be installed inside the mold body 1, thereby protecting and storing the connecting rod 402 and the baffle plate 403, so that the casting work can proceed normally. A plurality of equally distributed inclined blocks 704 are provided inside the rotating ring 703, and the bottoms of the plurality of inclined blocks 704 are fixedly connected to the rotating ring 703. The end of the air pipe 702 is aligned with the inclined surface of the inclined block 704, a connecting tube 705 is provided at the bottom of the rotating ring 703 and is fixedly connected thereto, a conical block 706 is provided inside the connecting tube 705, the inclined surface of the conical block 706 is aligned with the end of the connecting tube 705, a spring 707 is provided at the bottom of the conical block 706 and is fixedly connected thereto, a connecting block 708 is provided at the end of the spring 707 and is fixedly connected thereto, and the connecting block 708 is located on the outer wall of the contact rod 401 and contacts therewith; the gas generated by the air pump 701 will enter the interior of the rotating ring 703 from the air pipe 702, thereby pushing the rotating ring 703 to rotate in the mold body 1, thereby driving the connecting tube 705 and the contact rod 401 thereunder to rotate on the outer wall of the mold body 1, so that the contact area between the baffle plate 403 and the inner wall of the shaft is larger, which is more conducive to the deformation detection of different areas in the shaft, thereby providing more comprehensive detection data for the staff.
[0023] For another measuring piece 4, a connecting block 28 is provided on the outer wall of the contact rod 401, and the connecting block 28 slides relative to the contact rod 401. A magnet 9 is provided at the end of the connecting block 28, and the top of the magnet 9 is fixedly connected to the rotating ring 703. An airbag 2 10 is provided on one side of the connecting block 28 and is fixedly connected thereto. The airbag 2 10 has an elastic force that automatically recovers, and the end of the airbag 2 10 slides freely on the outer wall of the mold body 1. There is a magnetic force of mutual attraction between the end of the connecting block 28 and the magnet 9, and the height of the connecting block 28 from the ground is higher than the height of the connecting block 1 708 from the ground. This ensures that when the first measuring piece 4 stops rotating the rotating ring 703, the second measuring piece 4 will not collide with it during the subsequent rotation process, thereby ensuring that this detection unit 7 has good test performance.
[0024] When in use, when the staff uses the steel rope to lift the steel mold, the two baffle plates 403 extending from the outside of the mold body 1 will resist the inner wall of the shaft. If it moves to the deformed part in the shaft, the baffle plates 403 will resist this area, thereby driving the contact rod 401 into the inside of the socket 3. After the contact rod 401 contacts the contact piece 405 in the socket 3, an electrical signal will be transmitted to the inside of the integrated box 406, and then the collected data will be synchronously transmitted to the staff's receiving device, so as to obtain accurate shaft section deformation data in time, and then make appropriate adjustments to the area that exceeds the deformation threshold, so that the later pouring work has a good balance and improves the stability of the final support effect. On the other hand, the lifting process is also accompanied by the start-up of the air pump 701, which will send gas into the air pipe 702 and blow it to the multiple inclined blocks 704 at the bottom of the rotating ring 703, so that the rotating ring 703 rotates, thereby driving the connecting tube 705 and the magnet 9 to rotate synchronously. In this state, the two contact rods 401 on the outer wall of the mold body 1 will rotate accordingly, so that when the mold body 1 is lifted upward, the contact area of the baffle plate 403 and the contact area of the inner wall of the shaft are greatly increased, thereby further increasing the detection range of the deformation area and making the measured data more comprehensive. It is worth noting that during the rotation of the two contact rods 401, if a deformation area is detected, the resistance force will drive the end of the conical block 706 to disengage from the interior of the connecting tube 705, and drive the contact rod 401 to be inserted into the corresponding socket 3. At this time, the contact rod 401 and the resistance plate 403 will stop rotating, but will still be lifted along with the mold body 1. On the basis of accurately positioning the deformation area, the degree of deformation is also accurately measured, providing more accurate detection data for the staff. At the same time, the other contact rod 401 is still rotating with the rotating ring 703, and the flatness of other parts of the inner wall of the shaft is detected. Similarly, if a large deformation still occurs in other areas, the magnet 9 above the contact rod 401 will also be separated from the connecting block 2 8, and under the resistance effect, inserted into the corresponding socket 3 and the deformation detection is performed again, ensuring that the deformation state and data in the shaft are fully collected, so that the staff can adjust the deformation area in time to make the subsequent pouring and support work more stable and reliable.
[0025] According to the above embodiment, embodiment 2, A rangefinder 13 is provided at the bottom of the rotating ring 703 and is fixedly connected thereto, and the rangefinder 13 is electrically connected to the integrated box 406. A laser emitter 14 is provided on one side of the magnet 9 and the connecting tube 705 and is fixedly connected to both, and the laser emitter 14 is electrically connected to the integrated box 406. During the rising process, if the contact rod 401 is squeezed into the inside of the contact piece 405, the rangefinder 13 will automatically record the height from the ground here under the control of the integrated box 406, and transmit it to the staff in time. Similarly, the laser emitter 14 in the rising state will also have a preset range value. If the laser emitter 14 detects that the distance from the inner wall of the shaft is too large or too small, it will send an alarm signal to the integrated box 406, thereby reminding the staff to pay attention to the status of this area. The two cooperate with each other to provide the staff with more accurate detection data and provide good protection for the balance of subsequent pouring work.
