Description

Technical Field

[0001] This utility model relates to the field of water conservancy channel wall panel positioning technology, specifically to a wall panel positioning device for water conservancy construction. Background Technology

[0002] During the construction of water conservancy channels, in order to ensure the stability, seepage prevention, and service life of the channel structure, it is often necessary to install wall panels on the inner wall of the channel and inject cement grout for fixing and shaping. The positioning accuracy of the wall panels directly determines the quality of channel construction. If the positioning deviation is too large, it is easy to cause uneven cement grout injection, unbalanced stress on the wall panels, and thus cause problems such as channel leakage and structural deformation, increasing the later maintenance costs.

[0003] Currently available water conservancy construction wall panel positioning devices often suffer from fixed structures and poor adjustment flexibility. Some devices use rigid connection structures, making it impossible to adapt to the wall panel spacing and channel inner wall slope, resulting in limited versatility.

[0004] In addition, there are some adjustable positioning devices that can adjust the basic position, but the structural stability after adjustment is insufficient. During the cement grouting process, they are easily affected by the impact force of the grout and may shift, leading to positioning failure.

[0005] Therefore, a wall panel positioning device for water conservancy construction is provided to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide a wall panel positioning device for water conservancy construction to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wall panel positioning device for water conservancy construction, comprising a crossbeam, wherein two positioning plates are symmetrically fitted on the outer surface of the crossbeam, and detachable hinge A is installed on the opposite surfaces of the two positioning plates. Detachable hinge B is symmetrically suspended on the lower surface of the crossbeam, and an adjusting and tightening device is rotatably installed between the hinge B and the corresponding hinge A.

[0008] Preferably, the upper surface of the crossbeam has two symmetrical through-holes A, and the opposing surfaces of the two positioning plates each have a groove, in which a through-hole B is formed. The hinge A includes a U-shaped hinge joint A, and a long bolt A is fixedly installed on the outer surface of the U-shaped hinge joint A. The long bolt A passes through the corresponding through-hole B, and a nut A is screwed onto the outer surface of the long bolt A. The hinge B includes a long bolt B, which passes through the corresponding through-hole A, and a U-shaped hinge joint B is fixedly installed on the lower surface of the long bolt B. A bolt B is screwed onto the outer surface of the long bolt B.

[0009] Preferably, the adjusting and tightening device includes an adjusting cylinder with internal threads, an adapter integrally formed at the lower end of the adjusting cylinder, an adapter sleeve rotatably mounted on the outer surface of the adapter, the adapter sleeve being T-shaped and rotatably connected to a U-shaped hinge joint A via a pin, a threaded rod screwed into the adjusting cylinder, and a hinge joint fixedly mounted at the end of the threaded rod away from the adjusting cylinder, the hinge joint being T-shaped and rotatably mounted in a U-shaped hinge joint B via a pin.

[0010] Preferably, the upper and lower surfaces of the crossbeam are provided with a plurality of adjustment holes A, and insert plates are inserted into two corresponding adjustment holes A, with the opposing surfaces of the two insert plates fitting against the outer surface of the corresponding positioning plate.

[0011] Preferably, the front and rear surfaces of the crossbeam are provided with a plurality of adjustment holes B, which are staggered from the adjustment holes A, and the size of the adjustment holes B is the same as that of the adjustment holes A.

[0012] Preferably, two operating blocks are symmetrically fixedly installed on the upper outer surface of the regulating cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention achieves length adjustment through the screw transmission structure of the adjusting clamping device, and adapts to angle changes with the double rotation connection structure, ultimately forming a triangular support between the baffle, the crossbeam and the adjusting clamping device, which greatly improves positioning stability. Furthermore, the setting of multiple adjustment holes A and B further expands the adjustment range and fixing method, which can effectively adapt to the needs of different construction scenarios.

[0014] In addition, the detachable design of both hinge A and hinge B using bolt connections allows for individual replacement of damaged parts without the need for complete scrapping. Furthermore, the plug-in fixing method of the insert plate is easy to operate, reducing the operational difficulty for construction workers and improving construction efficiency.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This utility model provides a technical solution: A wall panel positioning device for water conservancy construction includes a crossbeam 1. Two positioning plates 2 are symmetrically fitted on the outer surface of the crossbeam 1. Removable hinges A3 are installed on the opposite surfaces of the two positioning plates 2. Removable hinges B4 are symmetrically suspended on the lower surface of the crossbeam 1. Adjustable clamping devices 5 are rotatably installed between the hinges B4 and the corresponding hinges A3.

[0025] It should be noted that, in combination Figure 3 , Figure 4 and Figure 5 As shown, two mounting holes A11 are symmetrically opened through the upper surface of the crossbeam 1. Grooves 22 are opened on the opposite surfaces of the two positioning plates 2. Mounting holes B23 are opened through the grooves 22. The hinge A3 includes a U-shaped hinge joint A31. Long bolts A32 are fixedly installed on the outer surface of the U-shaped hinge joint A31. The long bolts A32 pass through the corresponding mounting holes B23, and nuts A33 are screwed onto the outer surface of the long bolts A32. The hinge B4 includes a long bolt B41. The long bolt B41 passes through the corresponding mounting holes A11, and U-shaped hinge joints B42 are fixedly installed on the lower surface of the long bolt B41. Bolts B43 are screwed onto the outer surface of the long bolt B41.

[0026] When installing hinge A3, insert the long bolt A32 into the mounting hole B23 in the groove 22 of the positioning plate 2, ensuring that the U-shaped hinge joint A31 fits tightly against the positioning plate 2. Then, screw the nut A33 onto the other end of the long bolt A32 and tighten it. During tightening, a torque wrench can be used to control the tightening torque of the nut to avoid over-tightening and deformation of the positioning plate 2. When installing hinge B4, insert the long bolt B41 through the mounting hole A11 on the upper surface of the crossbeam 1, so that the U-shaped hinge joint B42 is located below the crossbeam 1, and then fix it with the nut B43. After installation, check whether the orientation of the U-shaped hinge joint A31 and the U-shaped hinge joint B4 is consistent to ensure that the adjusting and tightening device can be connected smoothly.

[0027] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the adjusting and tightening device 5 includes an adjusting cylinder 51 with internal threads. An adapter 52 is integrally formed at the lower end of the adjusting cylinder 51. An adapter sleeve 53 is rotatably mounted on the outer surface of the adapter 52. The adapter sleeve 53 is T-shaped and is rotatably connected to the U-shaped hinge joint A31 through a pin. A threaded rod 54 is screwed into the adjusting cylinder 51. A hinge joint 55 is fixedly mounted at the end of the threaded rod 54 away from the adjusting cylinder 51. The hinge joint 55 is T-shaped and is rotatably mounted in the U-shaped hinge joint B42 through a pin.

[0028] When connecting the adjusting and tightening device 5, first connect the adapter sleeve 53 to the U-shaped hinge joint A31 through the pin, and then connect the T-shaped hinge joint 55 at the end of the threaded rod 54 to the U-shaped hinge joint B42 through the pin. After the pin is installed, a cotter pin needs to be added to the end to prevent the pin from falling off during use.

[0029] During adjustment, the construction worker can hold the operating block 511 on the adjusting cylinder 51 with both hands and rotate the adjusting cylinder 51. Since the adjusting cylinder 51 is screwed to the threaded rod 54, rotating the adjusting cylinder 51 will drive the threaded rod 54 to move along the axis of the adjusting cylinder 51, thereby changing the overall length of the adjusting and tightening device 5. When the positioning plate 2 contacts the wall panel and reaches the preset tightening force, the rotation of the adjusting cylinder 51 is stopped. At this time, the self-locking property of the screw drive structure can ensure that the adjusted length remains stable, without the need for additional locking components.

[0030] Combination Figure 1 and Figure 3As shown, multiple adjustment holes A12 are provided through the upper and lower surfaces of the crossbeam 1. Insert plates 14 are inserted into two corresponding adjustment holes A12. The opposing surfaces of the two insert plates 14 are in contact with the outer surface of the corresponding positioning plate 2. Multiple adjustment holes B13 are provided through the front and rear surfaces of the crossbeam 1. The adjustment holes B13 are staggered from the adjustment holes A12. The size of the adjustment holes B13 is the same as that of the adjustment holes A12. By setting multiple staggered adjustment holes A12 and B13 between the upper and lower surfaces and between the front and rear surfaces of the crossbeam 1, the concentrated force on the holes at the same position of the crossbeam 1 can be avoided, ensuring the stability of the overall structure of the crossbeam 1. At the same time, the staggered distribution of multiple adjustment holes also provides more flexible options for the installation of the insert plates 14.

[0031] After the initial positioning and clamping of the positioning plate 2 is completed by adjusting the clamping device 5, according to the actual position of the positioning plate 2, select the two corresponding adjustment holes A12 or B13 on the crossbeam 1, and insert the insert plate 14 into the corresponding adjustment hole on the crossbeam 1 (select adjustment hole A12 or adjustment hole B13 according to actual needs) until the lower end of the insert plate 14 passes through the adjustment hole. At this time, the side of the insert plate 14 close to the positioning plate 2 is tightly fitted with the outer surface of the positioning plate 2. In actual production, the width of the middle part of the insert plate 14 is the same as the width of the adjustment hole, which ensures stability and allows for easy removal during disassembly.

[0032] Finally, to facilitate the rotation operation of the adjusting cylinder 51, two operating blocks 511 are symmetrically fixedly installed on the upper outer surface of the adjusting cylinder 51.

[0033] For example, when the construction environment is harsh or the adjusting clamping device 5 requires a large clamping force, the construction personnel can use tools such as adjustable wrenches or pipe wrenches to clamp the two operating blocks 511. The lever action of the tools will drive the adjusting cylinder 51 to rotate, which saves physical strength and ensures that the adjusting cylinder 51 and the threaded rod 54 are tightened to a sufficient degree.

[0034] Working principle: When using this wall panel positioning device for water conservancy construction, firstly, fix the two hinge pieces A3 to the corresponding positioning plates 2 with long bolts A32 and nuts A33 respectively. Then, fix the two hinge pieces B4 to the crossbeam 1 with long bolts B41 and nuts B43. Finally, connect the adjusting and tightening device 5 to the hinge pieces A3 and B4 respectively with pins.

[0035] Then, based on the design positions of the wall panels on both sides of the inner wall of the channel, combined with Figure 7 As shown, two or more sets of devices are placed together in a preset position between the wall panels.

[0036] Next, positioning adjustment is performed. During adjustment, the construction personnel rotate the adjusting cylinder 51 using the operating block 511. The screw connection between the adjusting cylinder and the threaded rod changes the length of the adjusting clamping device. When the adjusting cylinder rotates, the rotating connection structure between the adapter and the adapter sleeve, and between the T-shaped hinge and the U-shaped hinge B42, can adapt to angle changes, ensuring a smooth adjustment process. As the length of the adjusting clamping device increases, it will push the two positioning plates 2 to move to both sides along the crossbeam 1 until the positioning plates 2 are tightly fitted with the wall panel.

[0037] After positioning is completed, reinforcement is carried out. During reinforcement, select the appropriate adjustment hole A12 according to the position of positioning plate 2, and insert the insert plate 14 to form lateral support for positioning plate 2. If further fixation is required, auxiliary support components can be installed using adjustment hole B13. At this time, positioning plate 2, crossbeam 1 and adjusting and tightening device form a stable triangular support structure, which can effectively resist the impact force generated during cement grouting and prevent wall panel displacement.

[0038] Once the cement grout has solidified and reached its strength, remove the insert plate 14 in sequence, rotate the adjusting cylinder 51 in the opposite direction to shorten the adjusting clamping device, release the clamping force of the positioning plate 2 on the wall panel, and finally remove the connection between the hinge and the beam and positioning plate to complete the disassembly and recycling of the device for subsequent reuse.
