Technical Field

[0001] The invention belongs to the field of building construction, and in particular relates to an adjustable device and method for a self-adaptive angle pull-down tool rope. Background Art

[0002] In recent years, the theory of tireless frame construction of cable-supported grid structures in China has gradually matured. In the process of converting theory into application, the spoke-type cable net is pulled down to the design elevation by pulling down the tooling rope. In this link, the pull-down tooling rope and the concrete stand slab need to be anchored. The traditional weighted anchoring generates a large load on the concrete stand slab, and the hoop anchoring cannot adjust the load of the pull-down tooling rope. Summary of the Invention

[0003] In response to the above problems, the present invention proposes an adjustable device and method for a self-adaptive angle pull-down tooling rope.

[0004] The purpose of the present invention can be achieved through the following technical solutions: An adaptive angle pull-down tool rope adjustable device, comprising: A fixing unit, used for fixing to the main body of the building; A vertical adjustment unit is rotatably connected to the fixed unit by rotating the adjustment unit, and the vertical adjustment unit includes: A first conversion beam connected to the rotation adjustment unit; a second transfer beam spaced apart from the first transfer beam, the second transfer beam being connected to the first transfer beam via a connecting rod, the second transfer beam being movable along the connecting rod to adjust a spacing between the second transfer beam and the first transfer beam, the second transfer beam being locked to the connecting rod via a fixing assembly; The tooling rope is pulled down, passed through and locked to the second conversion beam.

[0005] Furthermore, the pull-down tooling rope is locked to the second transfer beam through an anchor and a hydraulic jack.

[0006] Furthermore, there are two connecting rods, which are symmetrically arranged along the pull-down tooling rope; each connecting rod is simultaneously passed through the first conversion beam and the second conversion beam, and the two ends of the connecting rod are respectively fixed to the first conversion beam and the second conversion beam by anchor bolts. The second conversion beam is also provided with a support tube and a hydraulic jack. The support tube is arranged on the second conversion beam and is sleeved on the anchor bolt, and the hydraulic jack is arranged on the support tube.

[0007] Furthermore, the self-adaptive angle pull-down tool rope adjustable device further comprises: a displacement measuring device for measuring the distance δ0 between the first conversion beam and the second conversion beam; The system control center determines whether the distance δ0 measured by the displacement measuring device is consistent with the preset distance value [δ]. If not, the system calculates the force F that needs to be added. The calculation formula is: F = Kδ; δ=δ0-[δ]; Where K is the proportionality coefficient; The hydraulic control device and the system control center control the hydraulic control device to regulate the hydraulic jack according to the calculated force F that needs to be increased.

[0008] Furthermore, the fixing unit includes: a third transfer beam, provided on one side of the concrete slab of the building body; The reaction beam is arranged on one side of the concrete beam of the building body and is connected and fixed to the third conversion beam through a connecting rod.

[0009] Furthermore, the rotation adjustment unit includes: The two ear plates are fixed to the fixing unit and the vertical adjustment unit respectively, and the two ear plates are rotationally connected through a pin shaft.

[0010] The present invention also provides a method for using an adjustable device for self-adapting an angle-pull-down tooling cable, comprising the steps of: Step 1: Pass the two connecting rods through the reaction beam and the third transfer beam, and fix the connecting rods, reaction beam and transfer beam with anchor bolts; Step 2: Fix the two ear plates with the mounting pins; Step 3: Pass the pull-down tooling cable through the second transfer beam, anchor and hydraulic jack, pass the two connecting rods through the first transfer beam and the second transfer beam, and fasten them with anchor bolts. Set two support cylinders above the second transfer beam, set two hydraulic jacks above the support cylinders, pass the connecting rods through the hydraulic jacks, and secure them with anchor bolts.

When the position of the tooling rope is pulled to the designed elevation, tighten the anchor bolts in the support tube and retract the hydraulic jack to achieve fine adjustment. Step 6: Through the relative rotation of the ear plate and the pin shaft, the lateral shear force generated by the connection between the pull-down tooling rope and the device is eliminated through the rotation action.

[0011] Furthermore, after step six, the following steps are also included: Step 7: Measure the distance δ0 between the first conversion beam and the second conversion beam using a displacement measuring device; Step 8: The system control center determines whether the distance δ0 measured by the displacement measuring device is consistent with the preset distance value [δ].

[0012] The beneficial effects of the present invention are as follows: the pull-down tooling rope is anchored on the vertical adjustment unit. This device realizes vertical displacement adjustment of the pull-down tooling rope by controlling the hydraulic jack, and performs radial displacement adjustment by rotating the ear plate and the pin shaft, and also avoids pressure load on the main structure.

C. The device is connected to the main structure only through a reaction beam, which is easy to dismantle and has low construction difficulty; D. The device is simple, no additional reinforcement is required on the main structure, and it is economical. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] The present invention provides an adaptive angle-adjustable pull-down cable device for adjusting the vertical displacement and rotation angle of the pull-down cable during construction, ensuring that the cable remains at the designed elevation. The device primarily comprises a fixing unit, a rotation adjustment unit, and a vertical adjustment unit. These units work in concert to achieve precise adjustment of the pull-down cable.

[0018] Rotation adjustment unit: The one-way rotation of the device is achieved through the ear plate 8 and the pin 9 to eliminate the lateral shear force.

[0019] Vertical adjustment unit: vertical displacement adjustment of the pull-down tooling rope 1 is achieved through the first conversion beam 61, the second conversion beam 62, the connecting rod 2, the first hydraulic jack 41, etc.

[0020] The fixed unit includes: The third transfer beam 63 is provided on one side of the concrete slab 11 of the building body.

[0021] The reaction beam 10 is arranged on one side of the concrete beam 12 of the building body and is connected and fixed to the third conversion beam 63 through the connecting rod 2.

[0022] Specifically, holes are provided in the third transfer beam 63 and the reaction beam 10, the spacing of which matches the arrangement of the connecting rods 2. The connecting rods 2 pass through these holes and are secured to the third transfer beam 63 and the reaction beam 10 via anchor bolts 3. This secures the fixing unit to the concrete structure of the building, providing stable support for the entire assembly.

[0023] In this embodiment, the connecting rod 2 is made of threaded steel.

[0024] The rotation adjustment unit includes: Ear plates 8: The two ear plates 8 are fixed on the fixing unit and the vertical adjustment unit respectively.

[0025] The pin 9 is passed through the holes of the two ear plates 8 to achieve a rotatable connection between the two ear plates 8 .

[0026] Specifically, one lug plate 8 is welded to the center of the third transfer beam 63, and the other lug plate 8 is welded to the center of the first transfer beam 61. The two lug plates 8 are connected by a pin 9, allowing the vertical adjustment unit to rotate unidirectionally relative to the fixed unit, thereby eliminating the lateral shear force generated at the connection between the pull-down tooling cable 1 and the device.

[0027] The vertical adjustment unit is used to adjust the vertical displacement of the pull-down tool rope 1. Its main components include: The first conversion beam 61 is connected to the ear plate 8 of the rotation adjustment unit.

[0028] The second conversion beam 62 is spaced apart from the first conversion beam 61 and connected to the first conversion beam 61 via the connecting rod 2 .

[0029] Connecting rods 2: There are two connecting rods 2, which are symmetrically arranged along the pull-down tooling rope 1. Each connecting rod 2 is passed through the first conversion beam 61 and the second conversion beam 62 at the same time and fixed by an anchor bolt 3.

[0030] The support tube 5 is provided on the second conversion beam 62 and sleeved on the connecting rod 2 .

[0034] The intelligent detection and control system includes: A displacement measuring device for measuring the distance δ0 between the first conversion beam 61 and the second conversion beam 62; The system control center determines whether the distance δ0 measured by the displacement measuring device is consistent with the preset distance value [δ]. If not, the system calculates the force F that needs to be added. The calculation formula is: F = Kδ; δ=δ0-[δ]; Where K is the proportionality coefficient; The hydraulic control device and the system control center control the hydraulic control device to regulate the hydraulic jack according to the calculated force F that needs to be increased.

[0035] It is understood that the hydraulic jacks controlled by the hydraulic control device include a first hydraulic jack 41 and a second hydraulic jack 42. Among them, the first hydraulic jack 41 can be fine-tuned and the second hydraulic jack 42 can be coarse-tuned. The hydraulic control device can select one or both of them to be regulated simultaneously according to actual needs.

[0036] Specifically, the displacement measurement device includes an ultrasonic transmitter, an ultrasonic receiver, and a data transmission device. The ultrasonic transmitter and receiver are used to ultrasonically measure the distance δ0 between the first conversion beam 61 and the second conversion beam 62. The data transmission device is used to transmit the distance δ0 to the system control center.

[0037] The system control center includes a data processing device, an algorithm control module, and an instruction sending device. The data processing device is used to process the data transmitted by the data transmission device. The algorithm control module is used to determine whether the distance δ0 measured by the displacement measurement device is consistent with the preset distance value [δ]. If not, the force F that needs to be increased is calculated using the following formula: F = Kδ; δ=δ0-[δ]; Where F is the force to be added, K is the proportional coefficient, δ is the distance difference, δ0 is the actual distance, and [δ] is the target value. The command is transmitted to the hydraulic control device through processing.

[0038] The instruction sending device is used to send instructions to the hydraulic control device.

[0039] The hydraulic control device includes a command receiving device, an electromagnetic drive unit, and a pressure sensor. The command receiving device receives commands from the command sending device. The electromagnetic drive unit controls the hydraulic jack.
