Description

Technical Field

[0001] The invention relates to the technical field of hydraulic climbing formwork height adjustment, and in particular to a climbing formwork height displacement monitoring and adjustment system for high pier construction of bridges. Background Art

[0002] During the bridge construction process, high pier construction is a very common construction method, which plays a very important role in the stability of the bridge. With the continuous construction of major transportation infrastructure around the world, the height of bridge piers is getting higher and higher, and the construction is becoming more and more difficult. In order to meet the needs of the project, a new formwork system: climbing formwork came into being. The emergence of climbing formwork construction technology has greatly reduced the difficulty of high pier construction and simplified the construction steps. With the gradual maturity of the technology, it has been gradually adopted in the process of bridge construction in my country, and its popularity has become increasingly higher, which has brought my country's high pier construction technology into a new stage and greatly improved the efficiency of bridge construction in my country.

[0003] Climbing formwork construction technology is a construction method that combines the characteristics of large formwork and sliding technology. The principle of hydraulic self-climbing formwork technology is that the lifting movement of the self-climbing formwork is achieved by alternately lifting the guide rail and the climbing frame through the hydraulic cylinder. The guide rail and the climbing frame are not related to each other, and the two can move relative to each other. When the climbing frame is working, the guide rail and the climbing frame are supported on the embedded support, and there is no relative movement between the two.

[0004] In the daily construction process of the existing climbing formwork construction technology, because the volume of the high pier is huge, it is necessary to use multiple groups of hydraulic cylinders to achieve the synchronous climbing of the formwork to ensure its stability and vertical height. However, in the climbing process, due to the loss of internal oil pressure of the hydraulic cylinder and the influence of special substances such as dust during the construction process, a small number of hydraulic cylinders cannot be lifted and lowered at the same distance during the lifting process, and the simultaneous lifting of multiple groups of devices is difficult to be quickly and accurately judged by the naked eye, which wastes manpower and fails to achieve the expected effect. The pier column tilts during the construction process, resulting in the accumulation of errors, increasing the side pressure of the wall and causing cracks, making it difficult to ensure the verticality of the high pier column and the stability of the climbing formwork frame during the construction process. However, when multiple groups of hydraulic cylinders are lifted and lowered at the same time, when one hydraulic cylinder is highly unstable, it will cause the formwork of other parts to tilt, and the weight will accumulate here, causing the hydraulic cylinder to bear too much extrusion from the arrival of unbalanced weight, resulting in a reduction in the service life of the hydraulic cylinder and the internal oil, causing additional damage.

[0005] Therefore, the present application provides a climbing formwork height displacement monitoring and adjustment system for high pier construction of bridges to meet the needs. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a height displacement monitoring and adjustment system for a climbing formwork frame for high pier construction of bridges to solve the problem that due to the loss of internal oil pressure of the existing hydraulic cylinders and the influence of special substances such as dust during the construction process, a small number of hydraulic cylinders cannot have the same lifting distance during the lifting and lowering process, and the simultaneous lifting and lowering of multiple groups of devices is difficult to quickly and accurately judge by the naked eye, which wastes manpower and fails to achieve the expected effect, resulting in the pier column tilting during the construction process, making it difficult to ensure the verticality of the high pier column and the stability of the climbing formwork frame during the construction process. However, when multiple groups of hydraulic cylinders are lifted and lowered at the same time, when one hydraulic cylinder becomes highly unstable, the formwork in other parts will be tilted, and the weight will accumulate here, causing the hydraulic cylinder to be overly squeezed by the unbalanced weight, resulting in a reduction in the service life of the hydraulic cylinder and the internal oil, and causing additional damage.

[0012] Optionally, the front end of the rack 2 is meshedly connected with a transmission gear rod, and the transmission gear rod is formed by a bevel gear, a rotating shaft and a wide gear being plugged into each other.

[0013] Optionally, the valve adjustment assembly includes a bevel gear, which is installed on one side of the transmission gear rod, and a double eccentric valve is installed at the bottom of the bevel gear. A wedge-shaped slider is provided at one end of the double eccentric valve, and two groups of wedge-shaped sliders are provided. The two groups of wedge-shaped sliders are symmetrically placed about the axial center of the double eccentric valve, and one end of the wedge-shaped slider is in contact with the edge of the double eccentric valve.

[0014] Optionally, an interactive valve is installed at the other end of the wedge-shaped slider, a spring is installed on one side of the wedge-shaped slider, both ends of the spring are respectively connected to one side of two groups of wedge-shaped sliders, and a guide tube is installed on the top of the interactive valve, and the internal size of the guide tube is consistent with the closing size between the interactive valves.

[0015] Optionally, the hydraulic control assembly includes a piston rod, which is installed at the bottom end of the sliding plate. The diameter of the piston rod is consistent with the size of the gap between the snap beads, and the outer surface of the piston rod is sleeved with a piston sleeve.

[0016] Optionally, an oil tank is installed on the outer surface of the piston sleeve, a connecting pipe is installed at one end of the oil tank, a valve block is inserted into the interior of the connecting pipe, and a hole is arranged inside the valve block.

[0017] Optionally, a liquid flow pipe is inserted into the interior of the valve block, the diameter of the liquid flow pipe is consistent with the hole size of the valve block, a liquid storage tank is installed at one end of the liquid flow pipe, and a control center is installed on one side of the liquid storage tank.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, by setting a sliding adjustment component, utilizing the cooperation between the sliding plate, the limit pile, the outer shell, the snap bead, the rack 1, the balance bar, the rack 2 and the transmission gear rod, when the hydraulic cylinder has a constant output and there is an unstable lifting change, it will cause a deviation in displacement. At the same time, due to the vertical characteristics of the hydraulic cylinder itself, the height deviation will cause itself to bear more force, resulting in defects in its own structure. The sliding plate will transfer the received force through twisting and tilting. When the sliding plate moves, the rack 1 moves laterally. At the same time, under the action of the lateral movement of the rack 1, the meshing and linked balance bar tilts, and the rack 2 moves vertically, which will drive the transmission gear rod to rotate. When the lifting height of the hydraulic cylinder itself changes, the sliding plate will convert this part of the force laterally according to its own tilt angle, thereby alleviating the damage to the hydraulic cylinder caused by uneven force.

[0020] By setting a sliding adjustment component in coordination with the valve adjustment component, using bevel gears, double eccentric valves, wedge-shaped sliders, springs, interactive valves and guide pipes, the inclination angle changes due to the change in the lifting height of the hydraulic cylinder. While alleviating the influence of its inclination angle on its own structure, the transmission gear rod rotates, driving the bevel gear to rotate. When the bevel gear rotates, the double eccentric valve connected thereto begins to rotate. Affected by the rotation of the double eccentric valve, the wedge-shaped slider collides with it, because the double eccentric valve rotates due to the rotation of the bevel gear, causing its angle to change, making the wedge-shaped slider unaffected by the power assistance and, at the same time, moved inwards under the action of the spring. At this time, the long teeth of the tightly closed interactive valve slowly separate Distance, forming an opening of a certain size. At this time, according to the feedback between the hydraulic cylinder and other groups of hydraulic cylinders, the value of its own height is obtained. When the height is high, under the action of internal pressure, the oil pressure circulates in the opposite direction, and gradually tends to a constant height. The piston rod is pushed upward, and after moving to the inside of the card bead, under the action of hydraulic pressure, the sliding plate gradually tends to the center position and then stops, so that the hydraulic cylinder and multiple groups of hydraulic cylinders in different positions tend to the same horizontal line, and rise vertically and smoothly, avoiding the situation of repeated confirmation by manpower. At the same time, the realization of unified rising height avoids the tilt of the formwork, the accumulation of construction errors, and the cracking caused by the tilt of the wall due to the influence of lateral pressure, thereby improving construction efficiency and reducing energy consumption.

[0021] By setting up a hydraulic control component, using the piston rod, piston sleeve, oil tank, connecting pipe, valve block, fluid pipe, fluid storage tank, and control center, when the vertical height of the hydraulic cylinder changes, the sliding block moves, driving the guide pipe to perform fluid infusion and extraction according to the height of the hydraulic cylinder and the pressure it is subjected to. When the oil changes, the oil inside the oil tank changes, and the internal pressure changes. The piston rod moves in the piston sleeve and fits with the output end of the hydraulic cylinder. At the same time, the oil inside the connecting pipe connected to it changes. When the oil inside the connecting pipe changes, the height of the valve block changes. The monitor detects that the height of the valve block has changed. When the constant value changes, the signal indicator The command generator transmits the signal to the control center. After receiving the command, the control center transports or extracts the oil in the storage tank through the connecting pipe to the oil tank, ensuring that the hydraulic cylinder can correct its own lifting height in a short time. According to the change of the lifting state of the hydraulic cylinder, the oil can be self-replenished, which reduces the construction error. It enables multiple groups of hydraulic cylinders to rise vertically and steadily on the same horizontal plane synchronously, avoiding the occurrence of accidents during the construction process and the increase of the construction period. At the same time, it avoids the accumulation of construction errors, which causes the wall surface of the high pier column to tilt and crack due to the influence of lateral pressure, thereby improving the construction efficiency, reducing energy consumption and labor costs, and reducing the impact of oil loss itself.

[0043] like Figures 1 to 13As shown, an embodiment of the present invention provides a height displacement monitoring and adjustment system for a climbing formwork frame for high pier construction of a bridge, comprising an operating platform 1, an outer guardrail 2 is installed on the top edge of the operating platform 1, a hydraulic control machine 3 is installed on the top of the operating platform 1, a mold shifting bracket 4 is arranged above the operating platform 1, a template 5 is installed at the front end of the mold shifting bracket 4, an embedded base 9 is arranged on the wall below the mold shifting bracket 4, a guide rail 12 is sleeved on the surface of the embedded base 9, an anti-fall climbing pile 10 is installed on the surface of the guide rail 12, a hydraulic cylinder 11 is installed at the bottom of the anti-fall climbing pile 10, and a monitor 14 is installed at the bottom of the anti-fall climbing pile 10 A signal command generator 15 is installed on one side of the monitor 14, a frame 13 is installed on the top of the guide rail 12, a sliding adjustment component 6 is installed on the output end of the hydraulic cylinder 11, the sliding adjustment component 6 receives the displacement of the hydraulic cylinder 11 caused by the height change, and triggers the start of the next component, a valve adjustment component 7, a valve adjustment component 7 is installed at the bottom of the sliding adjustment component 6, the valve adjustment component 7 controls the delivery of oil, a hydraulic control component 8, a hydraulic control component 8 is installed at the bottom of the valve adjustment component 7, and the hydraulic control component 8 extracts and delivers oil in an unquantified manner according to the degree of lifting and lowering of the hydraulic cylinder 11.

[0044] As an implementation method in this embodiment, Figures 4 to 9 As shown, the monitor 14 is installed at the bottom of the anti-fall climbing pile 10 and is placed at one end of the hydraulic cylinder 11. The monitor 14 is placed above the hydraulic control component 8. The sliding adjustment component 6 includes a sliding plate 61. The sliding plate 61 is installed at the output end of the hydraulic cylinder 11. A limit pile 62 is arranged at one end of the sliding plate 61. An outer shell 63 is installed at one end of the limit pile 62. A snap-in bead 64 is installed at the inner bottom end of the sliding plate 61. A rack 1 65 is installed on one side of the bottom end of the sliding plate 61. The bottom of the rack 1 65 is meshedly connected with a balance bar 66. A rack 2 67 is installed at one end of the balance bar 66. The front end of the rack 2 67 is meshedly connected with a transmission gear rod 68. The transmission gear rod 68 is formed by mutually plugging a bevel gear, a rotating shaft and a wide gear. When the sliding plate 61 is subjected to the tilting force of the hydraulic cylinder 11 When the sliding plate 61 moves, the protrusions on both sides of the sliding plate 61 allow it to slide in the grooves opened inside the outer shell 63, and the limit piles 62 installed inside the outer shell 63 will limit it to avoid excessive errors of the hydraulic cylinder 11 and damage to the structure. At the same time, when the sliding plate 61 slides, the rack 1 65 installed at the bottom moves horizontally synchronously. When the rack 1 65 moves synchronously, the center gear of the meshing balance bar 66 rotates, the balance bar 66 rotates, and the rack 2 67 is rotated by the balance bar 66 and also moves vertically. At the same time, the meshing transmission gear rod 68 is also rotated by the power of the vertical movement. When the hydraulic cylinder 11 is affected by the lifting height and generates lateral force for lateral conversion, the damage to the hydraulic cylinder 11 caused by uneven force is alleviated.

[0045] As an implementation method in this embodiment, Figures 9 to 11 As shown, the valve regulating assembly 7 includes a bevel gear 71, which is mounted on one side of the transmission gear rod 68. A double eccentric valve 72 is mounted at the bottom of the bevel gear 71. A wedge-shaped slider 73 is arranged at one end of the double eccentric valve 72. Two groups of wedge-shaped sliders 73 are arranged. The two groups of wedge-shaped sliders 73 are symmetrically placed about the axial center of the double eccentric valve 72. One end of the wedge-shaped slider 73 fits with the edge of the double eccentric valve 72. An interactive valve 75 is mounted on the other end of the wedge-shaped slider 73. A spring 74 is mounted on one side of the wedge-shaped slider 73. The two ends of the spring 74 are respectively connected to one side of the two groups of wedge-shaped sliders 73. The interactive valve 75 A guide tube 76 is installed on the top of the door 75. The internal size of the guide tube 76 is consistent with the closing size between the interactive valves 75. When the transmission gear rod 68 engaged with the bevel gear 71 rotates, it also rotates itself. At the same time, the double eccentric valve 72 rotates. When the double eccentric valve 72 rotates, the wedge slider 73 moves inward under the influence of the tension of the spring 74. When the wedge slider 73 moves inward, the interactive valve 75 connected to one side thereof begins to open. When the interactive valve 75 opens, the oil in the guide tube 76 begins to flow under the influence of pressure, providing oil support for the hydraulic cylinder 11 to avoid the occurrence of errors.

[0046] As an implementation method in this embodiment, Figure 12 to Figure 13 As shown, the hydraulic control component 8 includes a piston rod 81, which is mounted at the bottom end of the sliding plate 61, and the diameter of the piston rod 81 is consistent with the gap size between the clamping beads 64. The outer surface of the piston rod 81 is sleeved with a piston sleeve 82, and the outer surface of the piston sleeve 82 is mounted with an oil tank 83, and one end of the oil tank 83 is mounted with a connecting pipe 84, and the interior of the connecting pipe 84 is plugged with a valve block 85, and the interior of the valve block 85 is provided with holes, and the interior of the valve block 85 is plugged with a liquid pipe 86, and the diameter of the liquid pipe 86 is consistent with the hole size of the valve block 85, and one end of the liquid pipe 86 is mounted with a liquid storage tank 87, and one side of the liquid storage tank 87 is mounted with a control center 88. When the hydraulic control component 8 is affected by the oil transported by the guide pipe 76, the oil in the oil tank 83 The liquid acts on the valve block 85 through the connecting pipe 84, so that the position of the valve block 85 changes. After the monitor 14 monitors the displacement change of the valve block 85, the information is transmitted to the control center 88 through the signal command generator 15. When the control center 88 receives the command, it controls the oil pressure inside the liquid storage tank 87 and acts on the inside of the connecting pipe 84 through the liquid flow pipe 86, so that the position of the valve block 85 and other valve blocks 85 remain the same. At the same time, the oil tank 83 is acted upon by the pressure, so that the piston rod 81 in the piston sleeve 82 is inserted into the center position of the snap-in bead 64 inside the sliding plate 61 and stops at the inner wall of the sliding plate 61, thereby realizing self-replenishment of the oil and reducing the construction error, so that the multiple groups of hydraulic cylinders 11 are synchronously on the same horizontal plane and rise vertically steadily.

[0047] The working principle provided by the present invention is as follows: first, an operating platform 1 is arranged around the outer surface of the high pier column, and the operating platform 1 is kept vertically and stably placed on the ground. An outer guardrail 2 is installed along the outer edges of the operating platform 1. After the installation is completed, the embedded base 9 is installed along the outer surface of the high pier column, so that it is close to the surface of the high pier column and parallel to it, and fixed. After the embedded base 9 is installed, the guide rail 12 is connected and installed through the position of the embedded base 9, and its angle and vertical state are adjusted. After ensuring its vertical angle, a frame 13 is installed on the top of the guide rail 12 so that its bottom contacts the operating platform 1 and is stably placed. At the same time, when the frame 13 is installed, the mold moving bracket 4 is installed on the top of the frame 13, and the template 5 is installed at the same time to make it fit the outer surface of the high pier column and connected to the mold moving bracket 4. After the installation is completed, the anti-fall climbing pile 10 is installed on the guide rail 12, and the hydraulic cylinder 11 is fixed to the bottom of the anti-fall climbing pile 10.

[0048] The hydraulic control machine 3 is placed on the operating platform 1, and all the hydraulic cylinders 11 are connected to it, and then a monitor 14 is installed on the side of the hydraulic cylinder 11, and the infrared ray is aimed at the valve block 85 inside the connecting pipe 84, and a signal command generator 15 is installed next to the monitor 14. When the hydraulic cylinder 11 rises and the rising height of the hydraulic cylinder 11 changes, the sliding adjustment component 6 starts to operate, and the sliding plate 61 connected to the output end of the hydraulic cylinder 11 slides under the action of the tilting force. When the sliding plate 61 slides under the action of the tilting force, the limit pile installed inside the outer shell 63 62 is used to limit it to prevent the deviation angle from being too large and causing damage to the device. At the same time, when the sliding plate 61 slides, it drives the rack 1 65 to move horizontally. When the rack 1 65 moves, the meshing balance bar 66 rotates. When the balance bar 66 rotates, the rack 2 67 moves, and the meshing transmission gear rod 68 rotates at the same time. While buffering the tilting force generated by the height change of the hydraulic cylinder 11, it also brings power for the next step of starting the valve adjustment component 7. At the same time, the bevel gear 71 rotates due to the rotation of the meshing transmission gear rod 68.

[0049] When the bevel gear 71 rotates, the double eccentric valve 72 rotates. When the double eccentric valve 72 rotates, the wedge-shaped slider 73 moves inward under the influence of the tension of the spring 74. When the wedge-shaped slider 73 moves inward, the interactive valve 75 connected to one side of the wedge-shaped slider 73 begins to open until the size of the opening is equal to the size of the inner diameter of the guide tube 76. The hydraulic oil will perform corresponding infusion and drainage actions through the pressure brought by the hydraulic cylinder 11. When the height of the hydraulic cylinder 11 is higher, the oil will flow back into the oil tank 83. When the height of the hydraulic cylinder 11 is less than the height of other hydraulic cylinders 11, the oil in the hydraulic cylinder 11 will be supplemented. When the hydraulic control component 8 is affected by the oil transported by the guide tube 76, the oil tank 83 The density of the internal oil changes, and acts on the valve block 85 through the connecting pipe 84. When the position of the valve block 85 breaks the constant position, the monitor 14 collects the displacement distance and transmits it to the control center 88 through the signal command generator 15. When the control center 88 receives the command, it controls the oil pressure inside the liquid storage tank 87, acts on the liquid flow pipe 86 and transmits it to the connecting pipe 84, so that the valve block 85 is the same height as other valve blocks 85. The oil tank 83 is affected by the pressure, so that the piston rod 81 in the piston sleeve 82 is inserted into the center position of the snap-in bead 64 inside the sliding plate 61 and stops at the inner wall of the sliding plate 61, so that it returns to a stable center position and stops, so that its hydraulic cylinder 11 reaches the same height and stops.

[0050] The oil tank 83 is transported or extracted through the connecting pipe 84, which ensures that the hydraulic cylinder 11 can correct its own lifting height in a relatively short time. According to the change of the lifting state of the hydraulic cylinder 11, the oil can be self-replenished, which reduces the construction error. The multiple groups of hydraulic cylinders 11 can be synchronously and vertically raised on the same horizontal plane, which avoids the occurrence of accidents during the construction process and the increase of the construction period. At the same time, it avoids the accumulation of construction errors, which causes the high pier to tilt and the wall to crack due to the influence of lateral pressure, thereby reducing energy consumption and labor cost output, reducing the impact of oil loss itself, and improving construction efficiency.

[0051] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
