Description

A rapid installation guide and positioning system for large-segment irregular steel arch ribs and its usage method Technical Field

[0001] This invention relates to the field of steel arch rib construction technology, specifically to a rapid installation guide and positioning system for large-segment irregular steel arch ribs and its usage method. Background Technology

[0002] Large-segment irregular steel arch ribs are key load-bearing components in bridge and other engineering projects. They are mainly used in the main arch structure of arch bridges to bear the bridge deck load and transfer it to the foundation, combining strength and shape adaptability.

[0003] Existing large-segment irregular steel arch ribs are large in size and heavy in weight, and are easily affected by factors such as wind force and crane sway during hoisting. Therefore, in order to avoid this situation, a guide positioning system is used to assist in the rapid installation of steel arch ribs. However, the guiding principle of the traditional guide positioning system is mainly friction guidance, that is, relying on the contact friction between components to limit the displacement of the steel arch rib. But this method will cause friction damage during the rapid installation of steel arch ribs, and will also affect the installation speed due to frictional resistance.

[0004] Therefore, we propose a new rapid installation guide and positioning system for large-segment irregular steel arch ribs to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a rapid installation guide and positioning system for large-segment irregular steel arch ribs. By setting a new guide and positioning mechanism, the problem of friction damage to the steel arch ribs during rapid installation can be solved without affecting the installation speed of the steel arch ribs, thus solving the problems mentioned in the background art.

The groove on one end face of the limiting tube is used to guide the lubricating oil delivered from the corresponding bearing away.

[0010] Preferably, each guide frame is fixed with multiple reinforcing frames and limiting plates, one end of each limiting plate is fixedly inserted through the surface of each corresponding reinforcing frame, and the surface of each annular sealing gasket is in contact with the surface of the corresponding guide frame.

[0011] Preferably, each mounting base has multiple mounting blocks fixed on its front and rear surfaces, and each mounting block is mounted on the top of the bracket. Each mounting base also has a positioning block fixed on its front and rear surfaces. The top of the bracket has multiple positioning holes, and each positioning block is located inside each positioning hole.

[0012] Preferably, the support is provided with an auxiliary mechanism, which includes a placement plate. The bottom of the placement plate is in contact with the surface of the crossbar on the support. An oil tank and an oil pump are installed on the top of the placement plate. An oil inlet pipe is connected between the oil inlet end of the oil pump and the oil outlet end of the oil tank. A diversion pipe is connected to the oil outlet end of the oil pump. Each oil outlet end of the diversion pipe is connected to an electric regulating valve. The oil outlet end of one of the electric regulating valves is connected to a delivery pipe.

The top oil filling end of the oil tank is equipped with a sleeve.

[0015] Preferably, the sleeve has three perforated plates inside. The top of the upper perforated plate is fixed with a fixing ring, which is installed on the top of the sleeve. The middle perforated plate is movably sleeved inside the sleeve. The lower perforated plate is fixedly sleeved inside the sleeve. A processing block is provided between each pair of adjacent perforated plates.

[0016] A method for using a rapid installation guide and positioning system for large-segment irregular steel arch ribs includes the following steps:

[0017] S1. When steel arch ribs need to be installed, first use a floating crane to move the steel arch ribs to the top of the support. Then, use auxiliary wheels to guide the steel arch ribs down to the designated position. When the guide angle of the guide frame needs to be adjusted, first use the slings of the floating crane and the round holes on the top of the guide frame to lift the guide frame. Then, remove the L-shaped clamp and the perforated clamp in sequence. Next, use the rotating shaft and the mounting base to rotate the guide frame until it can no longer rotate. Finally, use the perforated clamp, the L-shaped clamp and the corresponding set of cylindrical holes to fix the guide frame with the adjusted angle.

[0018] S2. When it is necessary to replace one of the auxiliary wheels, remove the bolts and nuts on the two corresponding fixing plates, then remove the two fixing plates, and then remove the corresponding rotating rod, limit tube and bearing on the auxiliary wheel to be replaced. After that, remove the auxiliary wheel to be replaced from the inside of the corresponding auxiliary hole, replace it with a new auxiliary wheel, and at the same time, install the removed rotating rod, limit tube, fixing plate and bearing back into their original positions and fix them with bolts and nuts.

[0019] S3. When it is necessary to lubricate the bearings of all auxiliary rotating rods, the lubricating oil inside the oil tank is first drawn out through the control cabinet, oil pump, oil inlet pipe and distributor pipe, and then distributed to the two electric regulating valves with open valves. Then, the bearings are lubricated through the delivery pipe, distributor, oil supply pipe, check valve, connecting pipe, limit end on the fixed plate, annular sealing gasket and oil drain groove on the limit pipe, and excess lubricating oil is drained away.

[0020] S4. When the lubricating oil inside the oil tank is pumped out, the air in the environment will be squeezed into the oil tank due to atmospheric pressure. During the air transport process, the air will be processed by two processing blocks to remove moisture and oxygen. The processed air will then enter the oil tank to balance the atmospheric pressure.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, by setting a new guiding and positioning mechanism, the problem of friction damage to the steel arch rib during rapid installation can be solved without affecting the installation speed of the steel arch rib, thereby avoiding the cumulative installation error affecting the project quality. Through the cooperation of all fixing plates, all bearings, all rotating rods, all limiting tubes, all auxiliary holes and all auxiliary wheels, the steel arch rib can be guided downward without friction damage. Through the cooperation of the perforated clamp rod, L-shaped clamp plate, rotating shaft, mounting base and cylindrical hole, the guide frame can be angled and fixed after the angle adjustment is completed.

[0023] 2. In this invention, by cooperating the control cabinet, oil pump, oil inlet pipe, diverter pipe, two electrically adjustable valves with open valves, delivery pipe, diverter, oil supply pipe, check valve, connecting pipe, limit end on the fixed plate, annular sealing gasket and oil drain groove on the limit pipe, the lubricating oil in the oil tank can be drawn away, delivered to each bearing, and excess lubricating oil can be drained away.

[0024] 3. In this invention, by using a perforated plate and a sleeve together, the internal space of the sleeve can be divided into multiple areas. By using a processing block together, the air entering the oil tank can be dehydrated first and then deoxygenated, thereby preventing the lubricating oil inside the oil tank from oxidizing and deteriorating.

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.

[0037] Example 1: Please refer to Figures 1-6 and 9. This invention provides a technical solution: a rapid installation and guiding positioning system for large-segment irregular steel arch ribs, including a bracket 1 and a control cabinet 7. A guiding and positioning mechanism 2 is provided on the top of the bracket 1. The guiding and positioning mechanism 2 is used to guide and position the steel arch rib to a designated position. The guiding and positioning mechanism 2 includes two guide frames 201 and two mounting seats 202. A rotating shaft 203 is fixed to the front and rear surfaces of each guide frame 201. The rotating shaft 203 allows the guide frame 201 to rotate on the mounting seat 202. Each mounting seat 202 has two sets of cylindrical holes 204 pre-set. Each set of cylindrical holes 204 on the guide frame 201 has a perforated locking rod 205 inside. Each perforated locking rod 205 has an L-shaped locking plate 206 inside its two end through holes. Each guide frame 201 has multiple sets of mounting holes 207 pre-set on its guide end. A rotating rod 208 is rotatably connected between the interior of each set of mounting holes 207. Each guide frame 201 has multiple auxiliary holes 209 pre-set on its guide end. An auxiliary wheel 210 and a set of limiting tubes 211 are movably sleeved on the outer surface of each rotating rod 208. Each guide frame 201 has a fixing plate 212 on its front and rear surfaces. An annular ring is adhered to the limiting end surface of each fixing plate 212. The sealing gasket 215 and two mounting bases 202 are placed on top of the bracket 1. The lower side of each L-shaped clamping plate 206 contacts the top of the corresponding mounting base 202. Each auxiliary wheel 210 is located inside each auxiliary hole 209. The fixing plate 212 and the guide frame 201 are fixed to the rotating rod 208 by bolts and nuts. Each auxiliary wheel 210 is located between a corresponding set of limiting tubes 211. The opposite ends of each set of limiting tubes 211 contact the front surface of the guide end inner wall of the corresponding guide frame 201 and the rear surface of the guide end inner wall of the corresponding guide frame 201, respectively. The groove on one end face of the limiting tube 211 is used to pull the corresponding shaft... The lubricating oil delivered from the carrier flows away. Each guide frame 201 is fixed with multiple reinforcing frames 213 and limiting plates 214. One end of each limiting plate 214 is fixed through the surface of each corresponding reinforcing frame 213. The surface of each annular sealing gasket 215 is in contact with the surface of the corresponding guide frame 201. Multiple mounting blocks 3 are fixed on the front and rear surfaces of each mounting seat 202, and each mounting block 3 is installed on the top of the bracket 1. Positioning blocks 4 are fixed on the front and rear surfaces of each mounting seat 202. Multiple positioning holes 5 are preset on the top of the bracket 1, and each positioning block 4 is located inside each positioning hole 5.

[0038] In this embodiment, when the steel arch rib needs to be installed, the steel arch rib is first lifted by a floating crane and moved above the support 1. Then, the steel arch rib is lowered. When the lowered steel arch rib moves between the two guide frames 201, the steel arch rib continues to move downward. At this time, the lowered steel arch rib is assisted in being guided downward by all the fixing plates 212, all the bearings, all the rotating rods 208, all the limiting tubes 211, all the auxiliary holes 209, and all the auxiliary wheels 210. At the same time, the lowered steel arch rib is enhanced by the cooperation of all the limiting plates 214 and all the reinforcing frames 213. When the steel arch rib is guided and positioned to the designated location, the downward movement of the steel arch rib is paused. When it is necessary to adjust the guiding angle of the guide frame 201, before the steel arch rib is installed, the sling of the floating crane is first installed with the round hole at the top of one of the guide frames 201. Then, the corresponding L-shaped clamp 206 is removed from the corresponding perforated clamp 205. Next, the perforated clamp 205 is moved out from the interior of the corresponding set of cylindrical holes 204. Then, the guide frame 201 is rotated through the cooperation of the corresponding rotating shaft 203 and the corresponding mounting base 202 until it can no longer rotate. Until the guide frame 201 completes its rotation, insert the perforated clamp 205 directly into the corresponding set of cylindrical holes 204. Then, reinstall the removed L-shaped clamp 204 onto the perforated clamp 205 to complete the angle adjustment of one guide frame 201. Repeat the above steps to adjust the guide angle of the other guide frame 201. When both guide frames 201 have completed their angle adjustments, continue with the rapid installation of the steel arch rib. When it is necessary to replace one of the auxiliary wheels 210, remove the corresponding two fixing plates 21. Remove the bolts and nuts from the 2nd set of mounting plates 212, each with an annular sealing gasket 215. Then, remove the corresponding rotating rod 208 and bearing from the corresponding set of mounting holes 207 on the auxiliary wheel 210 that needs to be replaced. At the same time, remove the corresponding set of limiting tubes 211. Then, remove the auxiliary wheel 210 that needs to be replaced from the corresponding auxiliary hole 209 and replace it with a new auxiliary wheel 210. Finally, reinstall the two mounting plates 212 with annular sealing gaskets 215 that were removed back in their original positions and secure them with bolts and nuts.

[0039] Example 2: As shown in Figures 1-9, the guide positioning mechanism 2 includes two guide frames 201 and two mounting bases 202. Each guide frame 201 has multiple sets of mounting holes 207 pre-set on its guide end. A rotating rod 208 is rotatably connected between the interior of each set of mounting holes 207. An auxiliary wheel 210 and a set of limiting tubes 211 are movably sleeved on the outer surface of each rotating rod 208. A fixing plate 212 is provided on the front and rear surfaces of each guide frame 201. An annular sealing gasket 215 is adhered to the limiting end surface of each fixing plate 212. An auxiliary mechanism 6 is provided on the bracket 1. Structure 6 includes a placement plate 601, the bottom of which contacts the surface of the crossbar on the support 1. An oil tank 602 and an oil pump 603 are mounted on the top of the placement plate 601. An oil inlet pipe 604 connects the oil inlet of the oil pump 603 to the oil outlet of the oil tank 602. A diversion pipe 605 connects the oil outlet of the oil pump 603. Each outlet of the diversion pipe 605 is connected to an electric regulating valve 606. One outlet of the electric regulating valve 606 is connected to a delivery pipe 607. Multiple auxiliary rods 608 are fixed to the top of the placement plate 601. Each auxiliary rod 608 has a support... On the lower side of the support frame 1, multiple stabilizers 609 are installed. A delivery pipe 607 is movably sleeved between the through holes of the multiple stabilizers 609. The oil outlet of another electric regulating valve 606 and the oil outlet of the delivery pipe 607 are both connected to a distributor 610. Each oil outlet of each distributor 610 is connected to an oil delivery pipe 611. Each oil outlet of each oil delivery pipe 611 is connected to a one-way valve 613. Each oil outlet of each one-way valve 613 is connected to a connecting pipe 612. The oil outlet of each connecting pipe 612 is fixedly connected to the corresponding limiting end on the corresponding fixing plate 212. The annular sealing gasket 215 and the limiting end on the fixing plate 212 are used to deliver the lubricating oil from the corresponding connecting pipe 612 to the corresponding bearing. The top oil filling end of the oil tank 602 is equipped with a sleeve 614. The inside of the sleeve 614 is provided with three perforated plates 615. The top of the upper perforated plate 615 is fixed with a fixing ring 617. The fixing ring 617 is installed on the top of the sleeve 614. The middle perforated plate 615 is movably sleeved inside the sleeve 614. The lower perforated plate 615 is fixedly sleeved inside the sleeve 614. A processing block 616 is provided between two adjacent perforated plates 615.

[0040] In this embodiment, when lubrication is required for the bearings of all auxiliary rotating rods 208, the two electric regulating valves 606 are first activated and their opening degrees are adjusted. Once both valves are adjusted, the oil pump 603 is then activated. The activated oil pump 603, through the oil inlet pipe 604, first draws lubricating oil from the oil tank 602, then delivers it to the distribution pipe 605, and then distributes it to the two open electric regulating valves 606. Subsequently, the lubricating oil is drawn from one of the electric regulating valves 606. The lubricating oil passing through the interior of valve 606 is first delivered to the connected distributor 610, then distributed to all connected oil supply pipes 611, then to the corresponding check valve 613, then to the connecting pipe 612, then to the corresponding limiting end on the fixed plate 212, and then, through the corresponding annular sealing gasket 215, to the corresponding bearing. Finally, it is drained from the pre-drained groove on the corresponding limiting pipe 211. Simultaneously, the lubricating oil passing through the interior of another electric regulating valve 606 is first delivered to the connected supply pipe 607, then... The oil is sent to the distributor 610, then distributed to all connected oil pipes 611, then to the corresponding check valve 613, then to the connecting pipe 612, then to the corresponding limiting end on the fixed plate 212, and then, through the corresponding annular sealing gasket 215, to the corresponding bearing. Finally, it is drained from the pre-drained groove on the corresponding limiting pipe 211. When all bearings have completed lubrication, the oil pump 603 can be stopped directly. Simultaneously, when the lubricating oil inside the oil tank 602 is drawn away, due to the atmospheric pressure... Due to pressure, the air in the environment first passes through the through holes on the upper perforated plate 615 and comes into contact with the upper processing block 617. When the air passes through the interior of the upper processing block 617, the moisture carried in the air is absorbed and removed. Then, the pre-treated air passes through the through holes on the middle perforated plate 615 and comes into contact with the lower processing block 617. When the pre-treated air passes through the interior of the lower processing block 617, the oxygen in the air is absorbed and removed. Finally, the treated air passes through the through holes on the lower perforated plate 615 and enters the interior of the oil tank 602 to balance the atmospheric pressure.

[0041] The overall effect and working principle of the mechanism are as follows: When in use, the guide positioning mechanism 2 is positioned on the bracket 1 by cooperating with the positioning hole 5 and the positioning block 4. Then, the mounting base 202 is fixed on the bracket 1 by the mounting block 3. At the same time, the sleeve 614 is removed and an appropriate amount of lubricating oil is injected into the oil tank 602. Then, the sleeve 614 is returned to its original position. Next, the control cabinet 7 is installed around the construction site of the steel arch rib. At the same time, the control cabinet 7, all electric regulating valves 606 and oil pump 603 are electrically connected.

[0042] When everything is ready, the steel arch rib is first lifted by the floating crane and moved to the top of the support 1. Then the steel arch rib is lowered. When the lowered steel arch rib moves between the two guide frames 201, the steel arch rib continues to move down. At this time, the lowered steel arch rib will be assisted in the downward movement by all the fixed plates 212, all the bearings, all the rotating rods 208, all the limit tubes 211, all the auxiliary holes 209 and all the auxiliary wheels 210. At the same time, the strength of the guide positioning mechanism 2 is increased by all the limit plates 214 and all the reinforcing frames 213. When the steel arch rib is guided and positioned to the designated position, the downward movement of the steel arch rib is paused.

[0043] When it is necessary to adjust the guide angle of the guide frame 201, before the steel arch rib is installed, first install the sling of the floating crane with the round hole at the top of one of the guide frames 201. Then, remove the corresponding L-shaped clamp 206 from the corresponding perforated clamp 205. Next, move the perforated clamp 205 out from the inside of the corresponding set of cylindrical holes 204. Then, through the cooperation of the corresponding rotating shaft 203 and the corresponding mounting base 202, rotate the guide frame 201 until it can no longer rotate. When the guide frame 201 has completed the rotation operation, directly insert the perforated clamp 205 into the inside of the corresponding other set of cylindrical holes 204. Then, install the removed L-shaped clamp 204 back onto the perforated clamp 205 to complete the angle adjustment of one of the guide frames 201. Then repeat the above operation steps to adjust the guide angle of the other guide frame 201. When the angle adjustment of both guide frames 201 is completed, the steel arch rib can be quickly installed.

[0044] When it is necessary to replace one of the auxiliary wheels 210, remove the bolts and nuts that fix the two corresponding fixing plates 212. Then remove the two fixing plates 212, which both have annular sealing gaskets 215. Next, remove the corresponding rotating rod 208 and bearing on the auxiliary wheel 210 to be replaced from the inside of the corresponding set of mounting holes 207. At the same time, remove the corresponding set of limiting tubes 211. Then, take out the auxiliary wheel 210 to be replaced from the inside of the corresponding auxiliary hole 209, replace it with a new auxiliary wheel 210, and then reinstall the two fixing plates 212, which both have annular sealing gaskets 215, back into their original positions and fix them with bolts and nuts.

[0045] When lubrication of the bearings rotating all auxiliary rods 208 is required, first activate the two electric regulating valves 606 and adjust their opening degrees. Once both valves are adjusted, start the oil pump 603. The pump, via the inlet pipe 604, will first draw lubricating oil from the oil tank 602, then deliver it to the distributor pipe 605, and then distribute it to the two open electric regulating valves 606. The lubricating oil passing through one of the electric regulating valves 606 will then be delivered to the connected distributor 610, then to all connected oil supply pipes 611, then to the corresponding check valve 613, then to the connecting pipe 612, and finally... The lubricating oil is delivered to the corresponding bearing through the corresponding annular sealing gasket 215 and then drained from the oil drain groove reserved on the corresponding limit tube 211. At the same time, the lubricating oil passing through the other electric regulating valve 606 will first be delivered to the delivery pipe 607 connected to it, then to the distributor 610 connected to it, then to all the oil supply pipes 611 connected to it, then to the corresponding check valve 613, then to the connecting pipe 612, then to the corresponding limit end on the fixed plate 212, and then to the corresponding bearing through the corresponding annular sealing gasket 215. Finally, it will drain from the oil drain groove reserved on the corresponding limit tube 211. When all bearings have completed the lubrication operation, the oil pump 603 can be stopped directly.

[0046] Meanwhile, when the lubricating oil inside the oil tank 602 is pumped out, due to atmospheric pressure, the air in the environment will first pass through the through holes on the upper perforated plate 615 and come into contact with the upper processing block 617 (composed of silica gel particles). When the air passes through the interior of the upper processing block 617, the moisture carried in the air will be adsorbed and removed. Then, the pre-treated air will pass through the through holes on the middle perforated plate 615 and come into contact with the lower processing block 617 (composed of 13X molecular sieve particles). When the pre-treated air passes through the interior of the lower processing block 617, the oxygen in the air will be adsorbed and removed. Then, the treated air will pass through the through holes on the lower perforated plate 615 and enter the interior of the oil tank 602 to balance the atmospheric pressure.

[0047] The wiring diagram between the oil pump 603, the electric regulating valve 606 and the control cabinet 7 is a publicly disclosed technology in this field. The model can be selected according to the actual situation, so the control method and wiring between the oil pump 603, the electric regulating valve 606 and the control cabinet 7 will not be described in detail here.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
