[0003] The skeleton of an astronomical dome is generally composed of a chassis and a spherical frame. The diameter of an astronomical dome is generally more than 4 meters, which leads to the large diameter and weight of the spherical frame and chassis. It is difficult to fine-tune the position during the hoisting process, and the technical requirements for the hoisting master are stringent. In addition, the chassis is placed on the support rollers through hoisting, and the chassis and the support rollers are rotationally connected.

[0015] Compared with related technologies, the observatory on-site positioning construction platform provided by the present invention has the following beneficial effects: The present invention provides an on-site positioning construction platform for an observatory. Before hoisting the chassis, a plurality of fixing mechanisms are fixed to the surface of the base, and then the chassis is hoisted; when the chassis is hoisted to about 50 cm away from the support roller, the worker rotates the oil cylinder inside the support column to adjust the length of the oil cylinder, and slides the slide rod so that the slide rod drives the first splint and the second splint to enter the interior of the guide rail, rotates the rotating rod to adjust the distance between the first splint and the second splint, so that the first splint and the second splint are tightly attached to the interior of the guide rail; after the splint is installed, when it is necessary to adjust the position of the chassis, one of the driving mechanisms is opened, and the solenoid valve on the side wall of the connecting pipe corresponding to this driving mechanism is opened.

The slide bar moves to adjust the position of the chassis so that the chassis is aligned with the supporting roller, and then the driving mechanism is closed, the electromagnetic valves on the side wall of the feed hose and the connecting pipe are closed, and the electromagnetic valve on the side wall of the discharge hose is opened to lower the chassis. During the lowering process, the slide bar contracts, and the hydraulic oil continuously enters the storage airbag. As the pressure inside the storage airbag gradually increases, the resistance to movement of the slide bars gradually increases. Multiple slide bars tilt upward at a constant angle to support the chassis, increasing stability during the lowering process and ensuring accurate placement of the chassis on the support rollers. After the chassis is hoisted, at least three sets of clamps are placed inside the guide rails. The corresponding solenoid valves are all closed, allowing the slide bars to secure the chassis and prevent it from shifting on the support roller surface. Similarly, when hoisting the spherical frame, additional clamps are used to first clamp the steel frame on the side walls of the spherical frame. The position of the spherical frame is then adjusted according to the above steps, allowing it to be quickly installed on the chassis surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

The observatory's on-site positioning construction platform includes: a fixing mechanism 4, multiple fixing mechanisms 4 being mounted and fixed to the surface of the dome foundation 1, the surface of which is mounted with multiple support rollers 14 for supporting the chassis 2; a staircase 11 being mounted inside the dome foundation 1, a support plate 12 being fixedly connected to the surface of the dome foundation 1, multiple bases 13 being welded to the surface of the support plate 12, and the interior of the bases 13 being rotatably connected to the support rollers 14; a guide rail 21 being mounted on the inner sidewall of the chassis 2, the interior of which is engaged with the first and second magnetic clamping plates 36 and 37; to facilitate access to the surface of the dome foundation 1 via the staircase 11, workers can install clamping plates to adjust the position of the chassis 2; and the support rollers 14 supporting the chassis 2, securing it above the support plate 12.

[0020] The fixing mechanism 4 includes a fixing plate 41, and the fixing plates 41 with multiple "L"-shaped side walls are tightly attached to the surfaces of the dome foundation 1 and the support plate 12; a fixing seat 45 is fixed to the surface of the fixing plate 41; the side walls of the fixing seat 45 are symmetrically rotated and connected to the rotating plate 42; the side walls of the rotating plate 42 are provided with a card slot 43; the inside of the card slot 43 is slidably connected to a card plate 44 with a trapezoidal side wall, and the card plate 44 is slidably connected to the side wall of the base 13; the fixing plate 41 is placed on the side wall of the support plate 12, the rotating plate 42 is rotated so that the rotating plate 42 contacts the side wall of the base 13, and the card plate 44 with a trapezoidal side wall is inserted into the inside of the card slot 43 and moves along the side wall of the base 13. As the card plate 44 continuously enters the inside of the card slot 43 and continuously pulls the rotating plate 42 and the fixing plate 41, the fixing plate 41 is tightly fixed to the surfaces of the dome foundation 1 and the support plate 12.

[0021] The side wall of the fixing mechanism 4 is installed with a driving mechanism 5 for controlling the extension and retraction of the sliding rod 35, and a one-way valve 7 for controlling the movement direction of the hydraulic oil is installed inside the driving mechanism 5; the driving mechanism 5 includes an oil tank 51, which is fixed to the side wall of the fixing plate 41, and an oil replenishing pipe 510 is installed at the top of the oil tank 51; the interior of the oil tank 51 is rotatably connected to the crank connecting rod 55, and the interior of the oil tank 51 is installed with a cylinder 56, an oil inlet pipe 58 and an oil outlet pipe 59; the interior of the cylinder 56 is slidably connected to the second piston 57, and the second piston 57 is rotatably connected to the crank connecting rod 55, and the bottom end of the cylinder 56 is installed with the oil inlet pipe 58 and the oil outlet pipe 59, and the side wall of the oil outlet pipe 59 is connected to the feed hose 312. The first gear 52 is engaged with the second gear 54, and the side wall of the first gear 52 is connected to the drive shaft of the motor 53; and the side wall of the second gear 54 is installed with the crank connecting rod 55; the installation direction of the one-way valve 7 inside the oil inlet pipe 58 is opposite to the installation direction of the one-way valve 7 inside the oil outlet pipe 59, and the motor 53 is turned on, and the motor 53 drives the first gear 52 to rotate, and the first gear 52 drives the second gear 54 to rotate. The diameter of the first gear 52 is smaller than the diameter of the second gear 54, so that the first gear 52 drives the second gear 54 to rotate more effortlessly, reducing the load on the motor 53; the rotation of the second gear 54 drives the crank connecting rod 55 to rotate continuously, and the crank connecting rod 55 drives the second piston 57 to move up and down continuously inside the cylinder 56. The second piston 57 moves upward, the one-way valve 7 at the bottom end of the oil inlet pipe 58 is opened, the one-way valve 7 at the bottom end of the oil outlet pipe 59 is closed, and the second piston 57 moves to The upward movement draws the hydraulic oil inside the oil tank 51 into the interior of the cylinder 56 through the oil inlet pipe 58; when the second piston 57 moves downward, the one-way valve 7 at the bottom end of the oil inlet pipe 58 is closed, and the one-way valve 7 at the bottom end of the oil outlet pipe 59 is opened, and the second piston 57 draws the hydraulic oil inside the cylinder 56 into the interior of the oil cylinder 32 through the oil outlet pipe 59 and the feed hose 312, so that the hydraulic oil squeezes the first piston 39, driving the first piston 39 and the slide rod 35 to move inside the oil cylinder 32. The movement causes the slide rod 35 to move and push the chassis 2 to move; and the bottom area of ​​the second piston 57 is much smaller than the bottom area of ​​the first piston 39. According to Pascal's principle, the area of ​​the second piston 57 is small and the area of ​​the first piston 39 is large. A small force is applied to the second piston 57 to push the hydraulic oil into the interior of the cylinder 32, making it easier for the crank connecting rod 55 to squeeze the second piston 57, further reducing the load of the motor 53, and the position of the chassis 2 and the spherical skeleton 22 can be adjusted by a single motor 53.

[0022] The one-way valve 7 includes a limiting rod 71 and a closing block 73, and the limiting rod 71 and the closing block 73 are both installed inside the oil inlet pipe 58 and the oil outlet pipe 59; the closing block 73 has a funnel-shaped interior and an internal engaging ball 74, and the two ends of the second spring 72 are fixedly connected to the locking ball 74 and the limiting rod 71 respectively; when the liquid moves along the closing block 73 toward the limiting rod 71, the liquid pushes the locking ball 74 to move and compress the second spring 72, thereby opening the closing block 73 and allowing the liquid to flow out through the closing block 73; when the liquid moves along the limiting rod 71 toward the closing block 73, the second spring 72 pushes the locking ball 74 to block and seal the closing block 73, preventing the liquid from passing through the closing block 73, so that the liquid can only pass in one direction.

[0023] The surface of the fixing mechanism 4 is mounted with a positioning mechanism 3 for adjusting the position of the chassis 2 and the spherical skeleton 22; the positioning mechanism 3 includes a support column 31, the support column 31 is rotatably connected to the fixing mechanism 4, and the interior of the support column 31 is threadedly connected to the oil cylinder 32; the top of the support column 31 is threadedly connected to a plurality of screws 33, and the screws 33 press against the side walls of the oil cylinder 32; the interior of the oil cylinder 32 is slidably connected to the first piston 39 and the sliding rod 35, the bottom end of the sliding rod 35 is fixedly connected to the first piston 39, and the top end of the sliding rod 35 is rotatably connected to the first splint 36; the interior of the first splint 36 is rotatably connected to the rotating rod 38, the rotating rod 38 is threadedly connected to the second splint 37, and the first splint 36 and the second splint 37 engage the chassis 2 and the spherical skeleton. 22; The two ends of the oil cylinder 32 are respectively connected to the joints 34, and the connection places between the joints 34 and the oil cylinder 32 and the slide rod 35 are installed with sealing rings 310, and the side walls of the joints 34 are installed with a discharge hose 311 and a feed hose 312; the worker adjusts the length of the oil cylinder 32 by rotating the oil cylinder 32 inside the support column 31, so that one end of the slide rod 35 is in contact with the chassis 2 or the spherical skeleton 22. During the rotation of the oil cylinder 32, the joint 34 is rotationally connected to the oil cylinder 32. During the rotation of the oil cylinder 32, the joint 34 can be prevented from rotating, so that the discharge hose 311 and the feed hose 312 on the side wall of the joint 34 are entangled and folded with each other, so that the hydraulic oil can flow inside the pipeline, and the sealing ring 310 on the side wall of the joint 34 maintains the sealing inside the oil cylinder 32. Rotate the sliding rod 35 so that the sliding rod 35 drives the first clamping plate 36 and the second clamping plate 37 into the interior of the guide rail 21. The first clamping plate 36 and the second clamping plate 37 are magnetic, so that the first clamping plate 36 and the second clamping plate 37 are adsorbed on the side wall of the guide rail 21 to prevent the first clamping plate 36 and the second clamping plate 37 from falling; rotate the rotating rod 38, and the rotating rod 38 rotates inside the first clamping plate 36. The rotating rod 38 enters or pushes out the interior of the second clamping plate 37 to adjust the distance between the first clamping plate 36 and the second clamping plate 37, so that the first clamping plate 36 and the second clamping plate 37 are tightly attached to the interior of the guide rail 21 or clamp the side wall of the spherical skeleton 22.

[0024] The interior of the driving mechanism 5 is installed with an adjustment mechanism 6 for adjusting the movement resistance of the slide rod 35, and the adjustment mechanism 6 includes a storage air bag 61, and the storage air bag 61 is symmetrically installed inside the driving mechanism 5; a plurality of first springs 65 are installed obliquely inside the storage air bag 61, and the storage air bag 61 is connected to the discharge hose 311; a connecting pipe 63 is installed at the bottom end of the storage air bag 61, and the connecting pipe 63 is fixed to the interior of the driving mechanism 5 through a fixing frame 64, and the first spring 65 makes the interior of the storage air bag 61 in an expanded state, and the hydraulic oil inside the oil tank 51 can be absorbed through the connecting pipe 63, and the hydraulic oil inside the storage air bag 61 adjusts the hydraulic oil inside the oil cylinder 32, so that the slide rod 35 can move inside the oil cylinder 32 without the action of the driving mechanism 5.

[0025] A storage air bag 61 is installed inside the oil tank 51, and the connecting pipe 63 is installed inside the bottom end of the oil tank 51 through the fixing bracket 64. In order to make the bottom surface of the connecting pipe 63 located inside the bottom end of the oil tank 51, the hydraulic oil inside the oil tank 51 can be sucked into the storage air bag 61 through the connecting pipe 63, so that the storage air bag 61 always has hydraulic oil.

[0026] Solenoid valves 62 are installed on the side walls of the discharge hose 311 , the feed hose 312 , and the connecting pipe 63 , so that the discharge hose 311 , the feed hose 312 , and the connecting pipe 63 can be opened and closed by the solenoid valves 62 .

[0027] The working principle of the observatory on-site positioning construction platform provided by the present invention is: after the base 13 is welded, the fixed plate 41 is placed on the side wall of the support plate 12, the rotating plate 42 is rotated so that the rotating plate 42 contacts the side wall of the base 13, and the clamping plate 44 with a trapezoidal side wall is inserted into the interior of the clamping groove 43 and moves along the side wall of the base 13. As the clamping plate 44 continuously enters the interior of the clamping groove 43 and continuously pulls the rotating plate 42 and the fixed plate 41, the fixed plate 41 is tightly fixed to the surface of the dome foundation 1 and the support plate 12. When the cam 35 is in the air, the oil pump 32 is turned off, and the oil pump 32, which is used as the fuel tank 51 to move upward, is turned off, and the fuel tank 51 is turned off. When the cam 35 is in the air, the oil pump 32 is turned off, and the fuel tank 51 is turned off. When the cam 35 is in the air, the oil pump 32 is turned off, and the fuel tank 51 is turned off, the oil pump 32 is turned off, and the fuel tank 51 is turned off. When adjusting the position of the chassis 2, one of the motors 52 is turned on, and the solenoid valve 62 on the side wall of the connecting pipe 63 corresponding to the motor 52 is opened. As the motor 52 runs, the hydraulic oil enters one end of the cylinder 32 through the feed hose 312, pushing the first piston 39 and the slide rod 35 to move inside the cylinder 32. The first piston 39 transports the hydraulic oil at the other end of the cylinder 32 through the discharge hose 311 into the interior of the oil tank 51, thereby driving the slide rod 35 to extend and retract inside the cylinder 32; the slide rod 32 extends and retracts, rotates, and pushes the chassis 2 to move, thereby adjusting the position of the chassis 2.During the process of adjusting the position of the chassis 2, the feed hose 312 corresponding to the other motor 52 and the solenoid valve 62 on the side wall of the connecting pipe 63 are closed, and the solenoid valve 62 on the side wall of the discharge hose 311 is opened. The movement of the chassis 2 drives the other slide rods 35 and the first piston 39 to move inside the oil cylinder 32. The first piston 39 pushes the hydraulic oil into the interior of one of the storage air bags 61 through the discharge hose 311 on one side of the oil cylinder 32, and pushes the hydraulic oil into the other storage air bag 61 through the discharge hose 311 on the other side of the oil cylinder 32. 1. The hydraulic oil inside the oil cylinder 32 is kept full of hydraulic oil, which makes it easier for the chassis 2 to drive the other slide bars 35 to move, so that one or two of the motors 51 drive the slide bars 35 to move and adjust the position of the chassis 2. There is no need for workers to coordinate multiple motors 35 to drive the slide bars 35 to move and thus adjust the position of the chassis 2, which reduces the workload and difficulty of the workers. In addition, the chassis 2 pushes the slide bars 35 and the oil cylinder 32 against the inner wall of the chassis 2, thereby increasing the stability of the chassis 2 during movement. As the hydraulic oil enters the interior of the storage air bag 61, the internal pressure of the storage air bag 61 increases, which gradually increases the resistance to the movement of the chassis 2, thereby avoiding accidents caused by excessive movement of the chassis 2. When the resistance to the movement of the chassis 2 is too large, close all the solenoid valves 62 on the side walls of the discharge hose 311 and the feed hose 312, fix the positions of the slide rod 35 and the chassis 23, open all the solenoid valves 62 on the side walls of the connecting pipe 63, connect the storage air bag 61 with the oil tank 51, and the first spring 65 operates to discharge or replenish the hydraulic oil inside the storage air bag 61, so that the storage air bag 61 is reset. The above operation can be repeated to adjust the position of the chassis 2. The position of the chassis 2 can be adjusted by a single person operating one motor 53, which is easy to operate.After the chassis 2 is aligned with the support roller 14, the solenoid valves 62 on the side walls of all the discharge hoses 311 and the feed hose 312 are closed, and the solenoid valves 62 on the side walls of all the connecting pipes 63 are opened to reset the storage airbag 61. The solenoid valves 62 on the side walls of all the feed hoses 312 and the connecting pipe 63 are closed, and the solenoid valves 62 on the side walls of the discharge hose 311 are opened. All the motors 51 are turned off, and the chassis 2 is lowered using a crane. During the lowering process, the slide bar 35 contracts, hydraulic oil continuously enters the interior of the storage airbag 61, and the pressure inside the storage airbag 61 gradually increases, gradually increasing the resistance to the downward movement of the slide rod 35. Multiple slide rods 35 tilt upward from multiple angles to support the chassis 2, reducing the speed of the chassis 2 being lowered and buffering the movement of the chassis 2. At the same time, the slide rods 35 fix the chassis 2 from different angles, increasing the stability of the chassis 2 during the lowering process, so that the chassis 2 is accurately and slowly placed on the support roller 14. After the chassis 2 is hoisted, at least three sets of the first clamping plates 36 and the second clamping plates 37 are placed inside the guide rail 21. The solenoid valves 62 corresponding to these clamping plates are all closed, allowing the slide rods 35 to fix the chassis 2 and prevent it from shifting on the surface of the support roller 14. The other clamping plates inside the guide rail 21 are removed. Similarly, when hoisting the spherical frame 2, the clamping plates removed from the guide rail 21 are used to clamp the steel frame (as attached) on the side wall of the spherical frame 22. Figure 2 and attached Figure 4 As shown), the position of the spherical skeleton 2 is adjusted according to the above operations so that the spherical skeleton 22 can be quickly installed on the surface of the chassis 2.
