Description

Technical Field

[0002] In the past decade, ground-based external scaffolding, hanging baskets and external scaffolding have been gradually eliminated in construction projects due to their time-consuming, labor-consuming, material-consuming, safety-related and economical nature. Especially in the construction of high-rise and super-high-rise buildings, external scaffolding is used in large quantities, has a long service life, is expensive, and its practicality and safety need to be improved. Attached lifting scaffolding has become one of the main scaffolding methods for high-rise and super-high-rise building construction due to its advantages of low cost, fast installation, easy use and strong adaptability.

[0003] As the main load-bearing component of the attached lifting scaffolding, the guide rail is used to connect the upper and lower scaffolding boards, and cooperates with the wall-mounted supports to have the functions of guiding, unloading and anti-tilting. During the use and disassembly and transfer transportation process, due to the long components, they are easy to deform, causing the guide rail to bend as a whole. The deformation of the guide rail will have a great impact on the verticality of the frame, causing serious safety hazards. Since the guide rail is heavy, the traditional flame correction method consumes manpower and material resources, is difficult to calibrate accurately, has low efficiency, and cannot achieve the desired effect.

DETAILED DESCRIPTION

[0025] Reference Figure 1 to Figure 7 The present invention is specifically described. A correction device for an attached lifting scaffold guide rail comprises a correction platform 4 and a conductive limit stand 1 symmetrically arranged on both sides of the correction platform 4. The correction platform 4 is a rectangular box structure and two winches 8 are arranged in parallel in the box. A horizontal plate 4.1 is arranged on the upper part of the correction platform 4. A mounting plate 4.2 and a reaction frame 4.3 are arranged on the plate surface of the horizontal plate 4.1 at intervals and in parallel. Three hydraulic jacks 4.4 arranged at equal intervals are vertically fixed on the mounting plate 4.2. The conductive limit stand 1 is a horizontal frame with legs. Horizontal rollers 2 arranged at equal intervals are arranged on the upper part of the conductive limit stand 1. The horizontal rollers 2 and the horizontal plate 4.1 are located on the same horizontal plane. Vertical rollers 3 are arranged on both sides of the conductive limit stand 1. The vertical rollers 3 include a first vertical roller 3.1 and The second vertical roller 3.2 and the first vertical roller 3.1 are symmetrically arranged and fixed at a position at a distance of at least 1 meter from the end of the conduction limit stand 1 that is greater than the length of the guide rail 7 to be corrected. The second vertical roller 3.2 is staggered on the conduction limit stand 1 between the first vertical roller 3.1 and the correction platform 4. An electric lifting mechanism 6 is arranged on one side of the conduction limit stand 1. The electric lifting mechanism 6 lifts the guide rail 7 to be corrected upward and moves it to the horizontal roller 2 on the surface of the conduction limit stand 1. Hooks 11 are connected to both sides of the guide rail 7. The hooks 11 are respectively connected to steel wire ropes 10.3. The steel wire ropes 10.3 pass through the fixed pulley 10.2 and then are wound around the bottom of the conduction limit stand 1 and connected to the adjacent winch 8. The hydraulic push rod 4.4 and the second vertical roller 3.2 are both provided with stress plates, and the stress plates are connected to the control cabinet 5 through lines.

[0026] The electric lifting mechanism 6 uses an electric push rod, two of which are symmetrically arranged, and a steel plate for carrying the guide rail 7 is hinged at the bottom of the electric lifting mechanism 6. The vertical roller 3 is arranged in the vertical roller frame 9, and the vertical roller frame 9 is bolted to the conductive limit stand 1. The spacing between two adjacent first vertical rollers 3.1 is twice the spacing between two adjacent second vertical rollers 3.2. The two winches 8 are of the same model and are equipped with a synchronization device, which can realize the synchronous rope collection and release of the two winches 8 during work. The two winches 8 are respectively connected to a hook 11 through a wire rope 10.3, and the hook 11 is connected to the small cross bars at both ends of the guide rail 7.

[0027] The reaction frame 4.3 comprises an I-beam fixed vertically on the upper part of the horizontal plate 4.1, and a rib is arranged on the side of the I-beam facing away from the mounting plate 4.2.

[0028] The transport trolley 12 is a hollow rectangular box structure with front and rear openings, and wheels are arranged at the bottom. A steel plate on one side of the transport trolley 12 can be automatically raised and lowered, and the height of the lifting is greater than the height of the guide rail 7 and less than 1.5 times the height of the guide rail 7. The guide rail 7 to be corrected is placed in the transport trolley 12, which can be achieved by using power equipment, such as a winch or a crane to drag it.

[0029] The steps of working with the present invention are as follows:

[0030] Depend on Figure 8 It can be seen that the guide rail 7 to be corrected is first transported to the vicinity of the present invention by the transport trolley 12. The transport trolley 12 opens one side of the steel plate, and manually assists to remove a guide rail 7 to be corrected to the bearing steel plate of the electric lifting mechanism 6, ensuring that the guide rail 7 and the bearing steel plate are in two-point contact and remain stable.

[0031] Furthermore, the electric lifting mechanism 6 is used to lift the guide rail 7 to be corrected to a position higher than the conduction limit stand 1. An inclined stop block is arranged at the top of the electric lifting mechanism 6. Since the steel plate used to support the guide rail 7 at the bottom of the electric lifting mechanism 6 is hinged, when the guide rail 7 reaches the top, the steel plate contacts and collides with the stop block and flips over, thereby achieving the guide rail 7 falling on the horizontal roller 2 of the conduction limit stand 1.

[0032] Furthermore, two hooks 11 are respectively hung on the small cross bars on both sides of the guide rail 7, and the other side of the hook is connected to a wire rope 10.3, and the wire rope 10.3 is respectively connected to the winch 8 located at the bottom of the conductive limit stand 1. At the same time, a synchronization device is added between the two winches 8 so that the two can achieve synchronous linkage. That is: while one of the winches 8 is retracting the wire rope 10.3, the other winch 8 is releasing a wire rope 10.3 of the same length. Through the above movement, under the action of the winch 8, the guide rail 7 can achieve reciprocating motion between the vertical rollers 3 and the hydraulic jack 4.4 and the reaction frame 4.3 of the correction platform 4.

[0033] The hydraulic push rod 4.4 is adjusted to continuously move toward the reaction frame 4.3 until it is the same width as the guide rail 7. During the movement, there are a total of three hydraulic push rods 4.4 and they must be synchronously linked to achieve stable force on the guide rail 7 during the correction process.

[0034] There are two fixed pulleys 10.2 and they are arranged on the same vertical line. A rotating shaft is arranged in the middle of the fixed pulley 10.2 and the rotating shaft is fixed between two frame channel steels 10.1. The fixed pulley 10.2 and the frame channel steel 10.1 together form a pulley frame 10. The pulley frame 10 is fixed at both ends of the conduction limit stand 1 and is located on the center line of the conduction limit stand. The spacing of the first vertical rollers 3.1 located at the outermost group is 1.5 to 2 times the width of the guide rail. The width between the first vertical rollers 3.1 gradually decreases to the width of the guide rail 7 along the direction of movement toward the correction platform 4. It is fundamentally convenient for the guide rail 7 to enter between the second vertical roller 3.2 and the hydraulic jack 4.4 and the reaction frame 4.3.

[0035] The stress sheet of the hydraulic push rod 4.4 is arranged on the hydraulic push rod 4.4, and the stress sheet in the second vertical roller 3.2 is arranged on the rotating shaft of the second vertical roller 3.2. The stress sheet feeds back the force reading to the computer of the control cabinet 5 in real time through the data line. In this process, the control cabinet 5 with the computer constantly monitors the force of the whole movement process.

[0036] When the stress value of the stress gauge is zero, the computer sends a signal to the control cabinet 5, and the control cabinet 5 controls the hydraulic push rod 4.4 to push inward through the circuit. At this time, the force exerted by the hydraulic push rod 4.4 on the guide rail 7 increases, and the stress gauge reading also increases accordingly. Then, the control cabinet 5 controls the hoist 8 to work through the circuit, pulling the guide rail 7 to continue to reciprocate, and realizing the tightening correction of the guide rail 7 by the hydraulic push rod 4.4, until the reading of the stress gauge feedback is zero. At this time, the control cabinet 5 issues a command to stop the hoist 8, and then the movement of the guide rail 7 stops.

[0037] At this time, the control cabinet 5 continues to issue movement instructions to the hydraulic push rod 4.4, repeating the above process, and finally making the hydraulic push rod 4.4 squeeze the guide rail 7 to be corrected until the width is the same as the guide rail.

[0038] In order to ensure the correction quality of the guide rail 7, the hydraulic push rod 4.4 pushes the guide rail 7 at least three times during the above process.

[0039] Until the final stress sheet feedback force is zero, it can be considered that the correction of the guide rail 7 meets the expected requirements.
