DETAILED DESCRIPTION

[0033] The application will be described in further detail below with reference to the drawings. These drawings are simplified schematic diagrams and only show the basic structure of the application in a schematic manner, and thus only show the components relevant to the application.

[0034] In the description of the application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "arrangement", and "connection" should be understood broadly, for example, the term "connection" can be fixed connection, can also be detachable connection, or can be integral connection; can be direct connection, or can be indirect connection through an intermediate medium; can be internal communication of two elements or interaction relationship between two elements. Those skilled in the art can understand the specific meaning of the above terms in the application according to the specific circumstances.

[0035] The application discloses a large-span curved groove box combined continuous beam swivel spherical hinge monitoring and positioning method.

[0036] Reference Figure 2 A large-span curved groove box combined continuous beam swivel spherical hinge monitoring and positioning method, comprising the following steps:

[0037] S1, an infrared emitter and a laser range finder are installed at the end of the bridge body 2, the infrared emitter and the laser range finder vertically downwardly emit laser, a set of first swivel positioning members are installed at the laser point on the ground, the position is set as the starting point of the ground theoretical projection track line, and the center of the first swivel positioning member is aligned with the center of the laser point.

[0038] S2, the horizontal distance from the laser emission point of the infrared emitter and the laser range finder to the rotating center of the bridge body 2 is taken as a radius, the ground theoretical projection track line when the bridge body 2 rotates is marked on the flat ground by using instrument equipment, and infrared receivers are installed on the ground theoretical projection track line at intervals.

[0039] S3, set a group of second rotation positioning members at the terminal position of the theoretical ground projection trajectory line, the center of the second rotation positioning member coincides with the infrared emitter and the laser emitting point of the laser range finder after the bridge body 2 theoretically rotates into position. The first rotation positioning member and the second rotation positioning member can also use infrared receivers.

[0040] S4, the bridge body 2 starts to rotate, and it is observed whether the laser points emitted by the infrared emitter and the laser range finder on the ground coincide with the center points of the infrared receivers on the theoretical ground projection trajectory line, and at the same time, the downward distance is measured and compared with the theoretical vertical distance. If the spatial position coincides with the theoretical value, the bridge body 2 rotates normally. If the spatial position deviates greatly, corresponding measures are taken to process the bridge body 2 to continue to rotate. The bridge body 2 is assisted in positioning by the auxiliary positioning device 5 during the rotation process. During measurement, each infrared receiver needs to be triggered, and the angle needs to be set, otherwise it is considered to be deviated.

[0041] S5, after the bridge body 2 actually rotates into position, it is observed whether the laser points emitted by the infrared emitter and the laser range finder on the ground coincide with the center points of the rotation positioning members at the terminal position. If not, the longitudinal and lateral deviation values of the actual trajectory laser points and the theoretical trajectory laser points of the infrared emitter and the laser range finder and the deviation value of the actual vertical distance and the theoretical vertical distance of the bridge body 2 are observed, and then the hydraulic jack is used to fine-tune the posture of the bridge body 2 to make the bridge body 2 reach the theoretical positioning position, and then the concrete is poured between the upper deck 3 and the lower deck 4.

[0042] Reference Figures 2 to 4 The auxiliary positioning device 5 includes an auxiliary ring 51, which is installed on the lower deck 4 and is sleeved on the outside of the upper deck 3. The side wall of the auxiliary ring 51 is fixedly connected with a fixed block 52, and the fixed block 52 is fixedly connected with two guide rods 53, which are both arranged along the circumference of the upper deck 3. The same buffer rod 54 is sleeved on the two guide rods 53, and the buffer rod 54 is inserted between adjacent two support feet 32 to push the buffer rod 54 to rotate when the upper deck 3 rotates. The fixed block 52 is also fixedly connected with a positioning block 521. When the buffer rod 54 abuts against the positioning block 521, the bridge body 2 is rotated into position, and the bridge body 2 is positioned by physical contact.

[0043] The guide rod 53 is sleeved with a first compression spring 531, one end of the first compression spring 531 is in abutment with the fixed block 52, and the other end is in abutment with the buffer rod 54. The first compression spring 531 can provide support force for the buffer rod 54, thereby improving the stability of the bridge body 2 during rotation, and providing buffer for the bridge body 2 during rotation, thereby reducing the possibility of imbalance of the bridge body 2 during rotation. The side wall of the auxiliary ring 51 is fixedly connected with a plurality of clamping teeth 55 arranged in the circumferential direction of the auxiliary ring 51. The buffer rod 54 is hingedly connected with a clamping plate 541, and the buffer rod 54 is fixedly connected with a blocking step 542. The blocking step 542 is adapted to abut against the clamping plate 541, so that the clamping plate 541 can only rotate away from the fixed block 52. A torsion spring is arranged at the hinge connection between the clamping plate 541 and the buffer rod 54, so that the clamping plate 541 remains in abutment with the blocking step 542 without external intervention. When the buffer rod 54 moves along the guide rod 53, the clamping teeth 55 are adapted to clamp the clamping plate 541 to prevent the buffer rod 54 from moving away from the fixed block 52, thereby further supporting the bridge body 2 and preventing the bridge body 2 from rotating.

[0044] The fixed block 52, the guide rod 53, and the buffer rod 54 are arranged in multiple groups in the circumferential direction of the auxiliary ring 51 to improve the overall stability. The auxiliary ring 51 is formed by splicing a plurality of circular arc plates. Each circular arc plate is provided with a group of fixed blocks 52, guide rods 53, and buffer rods 54.

[0045] Referring to Figure 5 and Figure 6 , the lower deck 4 is provided with a protective device adapted to prevent pedestrians or animals from entering. The protective device includes a guardrail body 1, and a plurality of guardrail bodies 1 are connected end to end. One end of the guardrail body 1 at the bottom is hingedly connected with a bottom connecting rod 11 in the horizontal direction, and the other end is fixedly connected with a bottom connecting pin 112. The bottom connecting rod 11 is provided with a connecting hole 111 adapted to the insertion of the bottom connecting pin 112. The bottom of the guardrail body 1 is provided with an avoiding slot 12, and the bottom connecting pin 112 is fixedly connected to the slot wall of the avoiding slot 12. The avoiding slot 12 facilitates abutment with the bottom connecting rod 11 to make the heights of adjacent guardrail bodies 1 flush. The top of the guardrail body 1 is provided with a quick connection assembly adapted to connect with the top of the adjacent guardrail body 1.

[0046] During installation, the guardrail body 1 is lifted, the bottom connecting pin 112 is inserted into the connecting hole 111, and then the top of the adjacent guardrail body 1 is connected through the quick connection assembly, thereby realizing the quick disassembly and assembly of the adjacent guardrail bodies 1, facilitating the entry of workers, and reducing the possibility of animals and pedestrians entering by mistake.

[0047] The quick-connection assembly comprises a top connecting rod 131 and a sliding block 132. The top connecting rod 131 is hingedly connected to the top of the guardrail body 1 in the horizontal direction. The guardrail body 1 is provided with a clamping groove 14 for the insertion of the top connecting rod 131 on the adjacent guardrail body 1. A sliding groove 141 is formed in the top surface of the clamping groove 14. The sliding block 132 slides in the sliding groove 141. A fixing hole 1311 is formed in the top connecting rod 131 in the vertical direction for the insertion of the sliding block 132. When the sliding block 132 is simultaneously located in the sliding groove 141 and the fixing hole 1311, the top connecting rod 131 and the adjacent guardrail body 1 can be fixed, thereby realizing the connection of the two adjacent guardrail bodies 1.

[0048] The end of the sliding block 132 away from the fixing hole 1311 is fixedly connected with a pull rod 133. The end of the pull rod 133 away from the sliding block 132 extends out of the guardrail body 1 and is fixedly connected with a limiting block 134. The operator can easily lift the sliding block 132, thereby easily controlling the sliding block 132 to be separated from or enter the fixing hole 1311.

[0049] The pull rod 133 is further sleeved with a second compression spring 135. One end of the second compression spring 135 abuts against the sliding block 132, and the other end abuts against the top surface of the sliding groove 141. The second compression spring 135 can apply an elastic force to the sliding block 132, thereby preventing the sliding block 132 from being separated from the fixing hole 1311 without intervention. The end of the sliding block 132 away from the pull rod 133 is provided with an inclined surface 136. The inclined surface 136 is arranged in the direction in which the top connecting rod 131 enters the clamping groove 14. The inclined surface 136 is adapted to abut against the top connecting rod 131. When the top connecting rod 131 is rotated to be inserted into the clamping groove 14, the top connecting rod 131 first abuts against the inclined surface 136. The inclined surface 136 overcomes the elastic force of the second compression spring 135, thereby causing the sliding block 132 to retract into the sliding groove 141. This facilitates the entry of the top connecting rod 131 into the clamping groove 14. When the clamping groove 14 and the sliding groove 141 are aligned in the vertical direction, the sliding block 132 is inserted into the fixing hole 1311 under the action of the second compression spring 135. At this time, the top connecting rod 131 also abuts against the side wall of the clamping groove 14, thereby locking the top connecting rod 131 and realizing the connection of the two adjacent guardrail bodies 1.

[0050] The bottom connecting rod 11 is hingedly connected to the guardrail body 1. The angle between the bottom connecting rod 11 and the guardrail rod can be adjusted, thereby being combined into various shapes to adapt to different occasions.

[0051] The guardrail body 1 is provided with a plurality of reinforcing rods to improve the strength of the guardrail body 1.

[0052] Working principle: when rotating, the starting position is determined by the first rotating positioning member, during the rotation of the bridge body, whether the position of the bridge body deviates in the horizontal direction is judged by the infrared receiver receiving light, and whether the bridge body deviates in the vertical direction is determined by the laser range finder, then the bridge body is rotated to the position by the second rotating positioning member, the whole process of the bridge body rotation is monitored and positioned, and the safety of the bridge body rotation is improved.

[0053] When rotating, the support foot 32 pushes the buffer rod 54 to move, the first compression spring 531 supports the buffer rod 54, when the buffer rod 54 moves along the guide rod 53, the tooth 55 is suitable for clamping the clamping plate 541 to prevent the buffer rod 54 from moving away from the fixed block 52, further providing support for the bridge body 2, preventing the bridge body 2 from rotating.

[0054] When installing the protection device, the guardrail body 1 is lifted, the bottom connecting pin 112 is inserted into the connecting hole 111, and then the top of the adjacent guardrail body 1 is connected through the quick connecting assembly, thereby realizing the quick disassembly and assembly of the adjacent guardrail body 1, which is convenient for workers to enter and reduces the possibility of animals and pedestrians entering.

[0055] Through the setting of the second compression spring 135, the possibility of the slider 132 separating from the fixed hole 1311 is reduced. Through the setting of the pull rod 133, the slider 132 is easily lifted, thereby facilitating the quick separation of the slider 132 and the fixed hole 1311. Through the setting of the inclined surface 136, the top connecting rod 131 is directly clamped into the clamping groove 14 when inserted.

[0056] Based on the above ideal embodiments according to the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the contents of the specification, and the technical scope must be determined according to the scope of claims.
