Description

Technical Field

[0001] This invention relates to the field of sluice gate technology, specifically to a sluice gate waterstop steel plate hoisting and testing device. Background Technology

[0002] A sluice gate is a low-head hydraulic structure built on rivers and canals to control flow and regulate water levels. Sluice gates are generally made of water-stop steel plates, which are commonly used in reinforced concrete water-stop steel plate structures, dams, and other large-scale projects, such as tunnels, subways, dams, culverts, construction joints in water conservancy and hydropower projects, basements of high-rise buildings, and underground parking lots. Steel plate waterstops play a crucial role in infrastructure projects, underground facilities, tunnels, sewage treatment plants, water conservancy projects, and subways. During the hoisting of water-stop steel plates, to ensure stability, a detection device is needed to check for any tilting. If the water-stop steel plate is tilted, the position of the crane lifting it needs to be adjusted promptly.

[0003] The existing hoisting inspection equipment has a relatively uniform size, making it inconvenient to adjust the position of the inspection piece according to the length of the waterstop steel plate. When inspecting the hoisting status of the waterstop steel plate, the waterstop steel plate is prone to shaking because it is being lifted, which affects the accuracy of the inspection results. To address these issues, the existing equipment needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a hoisting and testing device for water-stop steel plates in sluice gates, in order to solve the problems mentioned in the background art, such as the limited size of existing hoisting and testing devices, the inconvenience of adjusting the position of the testing component according to the length of the water-stop steel plate, and the fact that the water-stop steel plate is prone to shaking when being hoisted, which affects the accuracy of the testing results.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sluice gate water-stop steel plate hoisting and testing device, comprising a movable base, a rotating plate rotatably connected to the top of the movable base, a groove formed in the rotating plate, a first bevel gear rotatably connected in the groove, a first lead screw fixed to the outer side of the first bevel gear, a first sleeve threadedly connected to the outer side of the first lead screw, the first sleeve penetrating through one of the two sides of the rotating plate and connected to a movable plate, support plates symmetrically fixed to the two sides of the upper surface of the movable plate, rollers rotatably connected to the inner end face of the support plates, guide blocks fixed to the inner end face of the support plates, a second bevel gear rotatably connected in the groove, a second lead screw fixed to the outer side of the second bevel gear, a second sleeve threadedly connected to the outer side of the second lead screw, the second sleeve penetrating through the other two sides of the rotating plate and connected to a movable block, a pressure sensor connected to the upper side of the movable block via a first compression spring, locking mechanisms movably connected to the four inner walls of the groove, and a driving mechanism fixed to the inner bottom of the groove.

[0006] Preferably, a first motor is fixed inside the movable base, and the top of the first motor is connected to the rotating plate.

[0007] By adopting the above technical solution, the direction of the rotating plate is adjusted according to the direction of the steel plate.

[0008] Preferably, the pressure sensor forms a telescopic structure with the moving block via a first compression spring.

[0009] By adopting the above technical solution, the first compression spring plays a supporting role for the pressure sensor.

[0010] Preferably, toothed rings are fixed to the outer sides of both the first lead screw and the second lead screw.

[0011] By adopting the above technical solution, the first lead screw and the second lead screw can be locked when the second tooth plate is engaged with the gear ring.

[0012] Preferably, the locking mechanism includes a slide groove, which is formed on the four inner walls of the groove. A first toothed plate is slidably connected in the slide groove, and a limit post is fixed in the slide groove, with the limit post passing through the first toothed plate.

[0013] By adopting the above technical solution, the slide and the limiting post play a limiting role for the first toothed plate.

[0014] Preferably, a second toothed plate is fixed to the outer side of the first toothed plate, a fixing plate is fixed in the groove, and the outer side of the fixing plate is connected to the second toothed plate by a second compression spring.

[0015] By adopting the above technical solution, the second toothed plate will be stably engaged and connected to the toothed ring under the support of the second compression spring.

[0016] Preferably, a spur gear is rotatably connected within the groove, and the spur gear meshes with the first toothed plate.

[0017] By adopting the above technical solution, the rotation of the circular gear will drive the corresponding first tooth plate to rise and fall.

[0018] Preferably, the driving mechanism includes an electric telescopic column, which is fixed to the inner bottom of the groove. A support box is fixed to the top of the electric telescopic column, and a square plate is fixed to the top of the support box. Racks are fixed to all four sides of the square plate.

[0019] By adopting the above technical solution, the lifting and lowering of the square plate will drive the rotation of the circular gear.

[0020] Preferably, a second motor is fixed inside the support box, and a rotating shaft is connected to the top of the second motor. A third bevel gear is fixed to the outside of the rotating shaft, and the top of the rotating shaft passes through the square plate and is connected to a fourth bevel gear.

[0021] By adopting the above technical solution, the third and fourth bevel gears will rotate together with the shaft.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This sluice gate water-stop steel plate hoisting and testing device can achieve the purpose of adjusting the spacing and limiting the position according to the thickness of the steel plate. The square plate can move up and down together with the support box. After the front and rear racks of the square plate are connected to the front and rear circular gears, the front and rear circular gears will rotate as the square plate descends. The corresponding first and second toothed plates will move up and disengage from the corresponding toothed rings, and the first lead screw will be unlocked. Then the third bevel gear rotates, driving the first bevel gear to rotate, and the first lead screw will rotate accordingly, thereby driving the first sleeve and the moving plate to move. This makes it convenient to adjust the spacing of the front and rear support plates according to the thickness of the steel plate. The support plates play a limiting role for the steel plate, which can effectively prevent the steel plate from shaking too much and affecting the accuracy of the test.

[0024] 2. This sluice gate water-stop steel plate hoisting and testing device can achieve the purpose of adjusting the spacing according to the length of the steel plate. After the left and right racks of the square plate are meshed and connected with the left and right spherical gears, the left and right spherical gears will rotate as the square plate rises. The corresponding first and second toothed plates will move down and disengage from the corresponding toothed rings, and the second lead screw will be unlocked. Then the fourth bevel gear rotates and drives the second bevel gear to rotate, and the second lead screw rotates accordingly, thereby driving the second sleeve and the moving block to move, so as to facilitate the adjustment of the spacing between the two moving blocks according to the length of the steel plate.

[0025] 3. This sluice gate waterstop steel plate hoisting and testing device can achieve the purpose of hoisting stability testing. When the direction of the rotating plate is adjusted and the steel plate is vertically hoisted between the front and rear support plates, the guide block can play a guiding role, so that the steel plate can be better lowered between the front and rear support plates. Then, the time difference between the pressure sensed by the two pressure sensors can be used to determine whether the steel plate is tilted. If the time difference exceeds the specified value, it means that the steel plate is tilted. At this time, the hoisting position needs to be adjusted in time. If the time difference does not exceed the specified value, it means that the steel plate is not tilted. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 6 This invention provides a technical solution: a hoisting and testing device for a sluice gate water-stop steel plate, comprising a movable base 1, a rotating plate 3 rotatably connected to the top of the movable base 1, a groove 4 formed in the rotating plate 3, a first bevel gear 5 rotatably connected in the groove 4, a first lead screw 6 fixed to the outer side of the first bevel gear 5, a first sleeve 7 threadedly connected to the outer side of the first lead screw 6, the first sleeve 7 penetrating through one or both sides of the rotating plate 3 and connected to a movable plate 8, support plates 9 symmetrically fixed to both sides of the upper end face of the movable plate 8, and a rotatably connected inner end face of the support plate 9. The inner end face of the roller 10 and the support plate 9 is fixed with a guide block 11. The second bevel gear 12 is rotatably connected in the groove 4. The outer side of the second bevel gear 12 is fixed with a second lead screw 13. The outer side of the second lead screw 13 is threadedly connected with a second sleeve 14. The second sleeve 14 passes through the other two sides of the rotating plate 3 and is connected with a moving block 15. The upper side of the moving block 15 is connected with a pressure sensor 17 through a first compression spring 16. Locking mechanisms 19 are movably connected to the four inner walls of the groove 4. A drive mechanism 20 is fixed at the inner bottom of the groove 4.

[0035] In this embodiment, as Figure 2 and Figure 3 As shown, a first motor 2 is fixed inside the movable base 1, and the top of the first motor 2 is connected to the rotating plate 3. The rotating plate 3 can rotate under the action of the first motor 2, so that the rotating plate 3 can be set perpendicular to the steel plate, thereby allowing the steel plate to be inserted more smoothly between the front and rear support plates 9.

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, the pressure sensor 17 forms a telescopic structure with the moving block 15 through the first compression spring 16. The first compression spring 16 supports the pressure sensor 17. After the steel plate is lifted and lowered between the front and rear support plates 9, if the two pressure sensors 17 can sense the pressure within the specified time difference range, it means that the steel plate is not tilted. If the time difference between the two pressure sensors 17 sensing the pressure exceeds the specified range, it means that the steel plate is tilted, which will affect the stability of the lifting. At this time, it is necessary to make timely adjustments.

[0037] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, gear rings 18 are fixed to the outer side of the first lead screw 6 and the outer side of the second lead screw 13. When the front and rear second gear plates 1904 are engaged with the gear rings 18 on the first lead screw 6, the first lead screw 6 can be locked. When the left and right second gear plates 1904 are engaged with the gear rings 18 on the second lead screw 13, the second lead screw 13 can be locked. When the front and rear second gear plates 1904 are disengaged from the gear rings 18 on the first lead screw 6, the first lead screw 6 can be unlocked. When the left and right second gear plates 1904 are disengaged from the gear rings 18 on the second lead screw 13, the second lead screw 13 can be unlocked.

[0038] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the locking mechanism 19 includes a slide groove 1901, which is formed on the four inner walls of the groove 4. A first toothed plate 1902 is slidably connected in the slide groove 1901. A limit post 1903 is fixed in the slide groove 1901 and passes through the first toothed plate 1902. When the spur gear 1907 rotates, it will drive the corresponding first toothed plate 1902 to slide up and down. The slide groove 1901 and the limit post 1903 play a limiting role for the first toothed plate 1902.

[0039] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a second toothed plate 1904 is fixed to the outer side of the first toothed plate 1902, and a fixing plate 1906 is fixed in the groove 4. The outer side of the fixing plate 1906 is connected to the second toothed plate 1904 through a second compression spring 1905. The second compression spring 1905 provides support to the second toothed plate 1904, enabling the second toothed plate 1904 to be more stably engaged with the corresponding toothed ring 18.

[0040] In this embodiment, as Figure 4 and Figure 5 As shown, a spur gear 1907 is rotatably connected in the groove 4, and the spur gear 1907 is meshed with the first toothed plate 1902. The rotation of the spur gear 1907 will cause the corresponding first toothed plate 1902 to slide up and down, and the corresponding second toothed plate 1904 will slide up and down accordingly, which facilitates locking or unlocking the first lead screw 6 and the second lead screw 13.

[0041] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the drive mechanism 20 includes an electric telescopic column 2001, which is fixed to the bottom of the groove 4. A support box 2002 is fixed to the top of the electric telescopic column 2001, and a square plate 2003 is fixed to the top of the support box 2002. A rack 2004 is fixed around the square plate 2003. The support box 2002 can move up and down under the telescopic action of the electric telescopic column 2001, thereby driving the square plate 2003 to move up and down. When the rack 2004 is meshed with the spur gear 1907, the spur gear 1907 will rotate as the square plate 2003 rises and falls.

[0042] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, a second motor 2005 is fixed inside the support box 2002, and a rotating shaft 2006 is connected to the top of the second motor 2005. A third bevel gear 2007 is fixed to the outside of the rotating shaft 2006, and the top of the rotating shaft 2006 passes through the square plate 2003 and is connected to a fourth bevel gear 2008. The rotating shaft 2006 can rotate under the action of the second motor 2005, thereby driving the third bevel gear 2007 and the fourth bevel gear 2008 to rotate as a whole. When the third bevel gear 2007 is meshed with the first bevel gear 5, the first bevel gear 5 will rotate with the rotation of the third bevel gear 2007. When the fourth bevel gear 2008 is meshed with the second bevel gear 12, the second bevel gear 12 will rotate with the rotation of the fourth bevel gear 2008.

[0043] The method of use and advantages of this invention: The working process of this sluice gate water-stop steel plate hoisting and testing device is as follows:

[0044] like Figures 1 to 6As shown: First, rotate the rotating plate 3 to the appropriate direction. The first lead screw 6 and the second lead screw 13 are initially locked. First, lower the support box 2002 and the square plate 2003. After the racks 2004 at the front and rear of the square plate 2003 mesh with the corresponding spur gears 1907, the two spur gears 1907 will rotate as the square plate 2003 descends, thereby driving the corresponding first gear plate 1902 and second gear plate 1904 to slide upward. The second gear plate 1904 disengages from the corresponding gear ring 18, thereby unlocking the first lead screw 6. At the same time, the third bevel gear 2... 007 is engaged with the first bevel gear 5. Then, the third bevel gear 2007 rotates, thereby driving the first bevel gear 5 and the first lead screw 6 to rotate. The first sleeve 7 is moved by the limiting action of the rotating plate 3 and the first lead screw 6, which facilitates the adjustment of the distance between the two support plates 9 according to the thickness of the steel plate. Then, the support box 2002 and the square plate 2003 are raised. The two second toothed plates 1904 at the front and rear move downward and engage with the corresponding toothed ring 18, thereby relocking the first lead screw 6. The racks 2004 on the left and right sides of the square plate 2003 engage with the corresponding spur gears 1907. After being connected, the two spur gears 1907 rotate as the square plate 2003 rises, thereby causing the corresponding first toothed plate 1902 and second toothed plate 1904 to slide downwards. The second toothed plate 1904 disengages from the corresponding gear ring 18, thus unlocking the second lead screw 13. At the same time, the fourth bevel gear 2008 meshes with the second bevel gear 12. Then, the fourth bevel gear 2008 rotates, thereby causing the second bevel gear 12 and the second lead screw 13 to rotate. The second sleeve 14 moves under the limiting action of the rotating plate 3 and the second lead screw 13, which facilitates adjustment according to the length of the steel plate. The distance between the two moving blocks 15 is adjusted, and then the square plate 2003 returns to its original position, thereby relocking the first lead screw 6 and the second lead screw 13. After the steel plate is vertically lifted, it can be lowered between the two support plates 9. The guide block 11 guides the steel plate, and the roller 10 can roll on the steel plate to facilitate the lowering of the steel plate. The steel plate will eventually press on the pressure sensor 17. If the steel plate is not tilted, the two pressure sensors 17 will sense the pressure within a specified time difference. If the steel plate is seriously tilted, the two pressure sensors 17 will sense the pressure successively for a longer period of time.

[0045] In summary, this sluice gate waterstop steel plate hoisting and testing device achieves the objectives of adjusting the spacing and limiting the position according to the steel plate thickness, adjusting the spacing according to the steel plate length, and testing the hoisting stability, thus meeting people's usage needs.
