Abstract
Description
Technical Field
[0001] This invention relates to the field of construction scaffolding technology, and particularly to a lifting construction scaffolding for building construction projects. Background Technology
[0002] Construction hoisting scaffolds consist of a hoisting motor, winch, wire rope, and a suspended platform. As is well known, the suspended platform is used to carry construction materials and personnel. The two ends of the suspended platform are connected to the free ends of the wire rope, which is wound around the winch. Driven by the hoisting motor installed at a high point on the building, the winch winds up and unwinds the wire rope, enabling the suspended platform to complete the hoisting operation. The suspended platform is used to lift and lower construction materials or personnel to different construction positions on the exterior wall of the building to complete the construction.
[0003] When the wire rope is connected to the suspended platform, the wire rope has a certain degree of flexibility and the length of the wire rope released from the winch is relatively long, which will cause the suspended platform to sway left and right during high-altitude operations. In particular, when the wire rope is used to change the left and right position of the suspended platform, the platform will shift significantly left and right due to its own weight. In particular, when the ratchet mechanism on the winch malfunctions, it will cause inaccurate construction positioning and cause excessive panic among the construction personnel. Summary of the Invention
[0004] This invention provides a lifting construction frame for building construction projects to solve the problems mentioned in the background art, such as the left and right displacement of the suspended platform, which causes inaccurate construction positioning and excessive panic among construction workers.
[0005] The technical solution of the present invention is a lifting construction frame for building construction projects, comprising a rectangular basket, a lifting frame mechanism disposed above the middle of the basket, a first adjustment mechanism disposed on the lifting frame mechanism, and a second adjustment mechanism disposed at the bottom of the basket.
[0006] The lifting frame mechanism includes a base and a lifting tube. A vertically upward rope tube is welded to the top of the base. The lifting tube is sleeved on the rope tube. The base has two wire grooves on the left and right sides, and the inner end of the wire groove is connected to the rope tube. Four steel wire ropes are threaded from the top of the rope tube into the rope tube. The four steel wire ropes are respectively threaded out from the four wire grooves and connected to the four corners of the suspended basket.
[0007] There are two first adjustment mechanisms, symmetrically located on the left and right sides of the lifting frame mechanism. Each of the first adjustment mechanisms includes an inclined tube welded to the left and right outer walls of the lifting pipe and a support tube welded to the front and rear sides of the inclined tube respectively. The inclined tube is located between the front and rear wire ropes. The front support tube extends toward the front wire rope, and the rear support tube extends toward the rear wire rope. The extended end of the support tube is equipped with a "V"-shaped fork around the periphery of the wire rope. The lifting pipe, carrying the inclined tube, can rotate back and forth around the rope tube.
[0008] The bottom of the suspended platform is provided with a footboard, and a through hole is opened in the middle of the footboard. A counterweight tube is welded in the through hole. The second adjustment mechanism includes a balance arm that is rotated on the counterweight tube through a bearing. The two sides of the balance arm extend from the counterweight tube to the left and right ends of the suspended platform, respectively. The second adjustment mechanism also includes a counterweight block fixed to the two extended ends of the balance arm.
[0009] As a further preferred embodiment, both the left and right inclined tubes include bent inclined portions and vertical portions. The inclined portions are connected to the hanging tubes and are located above the front and rear wire ropes. The inclined extension ends of the inclined portions extend to the left or right end of the suspended basket. The vertical portion is the extension end of the inclined portion and is perpendicular to the left or right end of the suspended basket. The bottom end of the vertical portion is close to the inner side of the left or right end of the suspended basket. The support tube is welded to the vertical portion. The "V"-shaped forks at the front and rear ends of the support tube are horizontally arranged between the front and rear wire ropes. The "V"-shaped opening of the front "V"-shaped fork faces the front wire rope, and the "V"-shaped opening of the rear "V"-shaped fork faces the rear wire rope. The distance between the front and rear wire grooves on the hanging seat is less than the distance between the connection points of the front and rear ends of the front and rear wire ropes respectively connected to the top of the suspended basket.
[0010] As a further preferred embodiment, the diameter of the hanging bracket is larger than the diameter of the rope tube.
[0011] As a further preferred embodiment, a hanging plate is welded to both the outer wall of the hanging pipe and the top surface of the hanging seat, and a bending spring is connected between the hanging pipe and the hanging seat through the hanging plate.
[0012] As a further preferred embodiment, the top end of the counterweight tube protrudes upward from the upper surface of the pedal, the counterweight tube and the hanging seat are on the same vertical line, and a counterweight ring is provided around the counterweight tube. The counterweight ring is sleeved and fixed around the counterweight tube, and the counterweight ring is an annular cone that gradually slopes downward from the top end of the counterweight tube.
[0013] As a further preferred embodiment, a rotating wheel assembly is provided at each of the left and right rear ends of the suspended basket. The rotating wheel assembly includes a wheel frame fixed to the suspended basket and a brake wheel rotated on the wheel frame. The wheel frame extends beyond the rear side of the suspended basket and restricts the brake wheel to extend beyond the rear side of the suspended basket.
[0014] As a further preferred embodiment, the counterweight is an arc-shaped counterweight plate, and the center of the arc of the counterweight is concentric with the balance arm. The wheel assembly also includes a brake mechanism fixed on the wheel frame. The brake mechanism on the left side is located on the rotation path of the left counterweight as it rotates with the balance arm, and the brake mechanism on the right side is located on the rotation path of the right counterweight as it rotates with the balance arm.
[0015] The braking mechanism includes a hanging plate fixed to the wheel frame, a through hole opened on the hanging plate, and a brake rod passing through the through hole. One end of the brake rod is close to the brake wheel and is provided with a brake pad that can press against the brake wheel. The other end of the brake rod is located outside the hanging plate and is located on the rotation path of the counterweight as it rotates with the balance arm. A limit stop is welded on the brake rod, and a return spring is provided between the limit stop and the outer side of the hanging plate. The return spring is sleeved on the brake rod.
[0016] As a further preferred embodiment, the bottom surface of the pedal is provided with four limiting shafts, two of which are located on the front side of the balance arm, and the other two of which are located on the rear side of the balance arm.
[0017] The beneficial effect of this invention compared to the prior art is that, when the suspended platform is lifting and lowering personnel, if a sudden stop or work stoppage occurs due to a winch brake malfunction, causing the wire rope to rapidly release its length and resulting in severe left-right swaying of the suspended platform, the aforementioned losses obviously cannot solve this prominent left-right swaying problem. The suspended platform will still experience excessive left-right swaying due to high-altitude operations. Construction workers inside the suspended platform can adjust its balance to gradually reduce the swaying amplitude. Construction workers hold the inclined tube and rotate it back and forth. The inclined tube will then rotate back and forth along with the support tube. When rotating forward, it can support the front "V"-shaped fork on the front wire rope. When rotating backward, it can support the rear "V"-shaped fork on the rear wire rope. Through the forward and backward rotation of the front and rear "V"-shaped forks, the front and rear wire ropes are compressed respectively, which can reduce the left-right swaying amplitude of the suspended platform.

[0028] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0029] In one implementation, such as Figures 1-9 As shown.
[0030] This embodiment provides a lifting construction frame for building construction projects, including a rectangular suspended basket 1, a lifting frame mechanism 2 located above the middle of the suspended basket 1, a first adjustment mechanism 3 located on the lifting frame mechanism 2, and a second adjustment mechanism 4 located at the bottom of the suspended basket 1.
[0031] The lifting frame mechanism 2 includes a hanging base 21 and a hanging pipe 22. A vertically upward-facing rope pipe 211 is welded to the top of the hanging base 21. The hanging pipe 22 is sleeved on the rope pipe 211. Two wire grooves 212 are opened on the left and right sides of the hanging base 21. The inner end of the wire groove 212 is connected to the rope pipe 211. Four steel wire ropes 5 are threaded from the top of the rope pipe 211 into the rope pipe 211. The four steel wire ropes 5 are respectively threaded out from the four wire grooves 212 and connected to the four corners of the suspended basket 1. The top ends of the four steel wire ropes 5 are connected to the winch after passing through the top of the rope pipe 211, so as to realize lifting.
[0032] like Figure 3 , Figure 6 as well as Figure 7 As shown, four wire ropes 5 are threaded through the four wire grooves 212 on the suspension base 21 and four holes on the rope tube 211 that communicate with the wire grooves 212, so that the bottom ends of the four wire ropes 5 are positioned in four directions and connected to the four corners of the suspended basket 1 respectively, ensuring that the suspended basket 1 is level when it is hoisted and used, and reducing swaying when lifting and lowering people.
[0033] In this embodiment, a vertically upward-facing rope tube 211 is installed at the top of the suspension base 21. The rope tube 211 can hold the four steel wire ropes 5 together in the tube cavity, and then pass them outward from the hole at the bottom of the rope tube 211 into the wire groove 212. After passing them out of the four wire grooves 212 in sequence, they are connected to the four corners of the suspended basket 1 in four directions. When the four steel wire ropes 5 are connected to the four corner surfaces of the suspended basket 1, the adjacent two steel wire ropes 5 form a triangular distribution pattern. As can be seen from the figure, the triangles formed by the four steel wire ropes 5 are located on the four surfaces above the suspended basket 1, which is equivalent to forming four solid areas on the suspended basket 1. In addition, the four wire grooves 212 on the suspension base 21 can position the four steel wire ropes 5 in four positions, which can also reduce the back and forth swaying.
[0034] In this embodiment, a first adjustment mechanism 3 is also provided between the front and rear steel wire ropes 5 on the left side, and the same first adjustment mechanism 3 is also provided between the front and rear steel wire ropes 5 on the right side. The first adjustment mechanism 3 includes an inclined tube 31 welded to the left and right outer walls of the lifting pipe 22 and a support tube 32 welded to the front and rear sides of the inclined tube 31 respectively. The inclined tube 31 is located between the front and rear steel wire ropes 5. The front support tube 32 extends toward the front steel wire rope 5, and the rear support tube 32 extends toward the rear steel wire rope 5. The extended end of the support tube 32 is equipped with a "V"-shaped fork 321 surrounding the steel wire rope 5. The lifting pipe 22, with the inclined tube 31, can rotate back and forth around the rope tube 211.
[0035] When the suspended platform 1 is lifting or lowering personnel, if a sudden stop or halt in operation occurs due to a winch brake malfunction, causing the wire rope 5 to rapidly release its length and resulting in severe left-right swaying of the suspended platform 1, the aforementioned losses obviously cannot resolve this prominent left-right swaying. The suspended platform 1 will still experience excessive left-right swaying due to high-altitude operations. Construction personnel inside the suspended platform 1 can adjust its balance to gradually reduce the swaying amplitude. By holding the inclined tube 31 and rotating it back and forth, the inclined tube 31 will cause the support tube 32 to rotate back and forth. When rotating forward, it can... The front "V"-shaped fork 321 can support the front wire rope 5. When rotating backward, it can support the rear "V"-shaped fork 321 on the rear wire rope 5. The wire rope 5 will swing back and forth. The back and forth swinging motion of the wire rope 5 is exactly the same as the left and right swaying of the suspended basket 1, which forms a shearing force. The shearing force is used to stop the swaying. Through the front and rear rotation of the front and rear "V"-shaped forks 321, the front and rear wire ropes 5 are squeezed in front and back respectively, which can quickly reduce the left and right swaying amplitude of the suspended basket 1 and eventually stop it.
[0036] In this embodiment, regarding the connection of the lifting pipe 22 to the rope pipe 211: Since the top end of the inclined pipe 31 is connected to the lifting pipe 22, and the lifting pipe 22 is connected to the rope pipe 211, and the rope pipe 211 is precisely the conjoined body where four steel wire ropes 5 pass through vertically, the suspended basket 1 sways left and right. When the steel wire ropes 5 are pushed back and forth by the "V"-shaped fork 321 and the sway is reduced, the rotation center of the lifting pipe 22 is located on the rope pipe 211, and the rope pipe 211 is directly above the top of the suspended basket 1. Therefore, when the left and right sway of the suspended basket 1 is reduced by manipulating the steel wire ropes 5 to swing back and forth, the suspension seat 21 is used as the rotation center of the lifting pipe 22, and also as the rotation center of the steel wire ropes 5 when swinging back and forth, which can ensure that the suspended basket 1 is horizontal when swinging back and forth.
[0037] In this embodiment, the bottom of the suspended platform 1 is provided with a foot pedal 101 for easy footwork during construction. A through hole 102 is opened in the middle of the foot pedal 101, and a counterweight tube 6 is welded into the through hole 102. The counterweight tube 6 is directly below the suspension seat 21. Since the suspension seat 21 is located above the center of the suspended platform 1, the counterweight tube 6 is equivalent to the lower center of gravity of the suspended platform 1. The top of the counterweight tube 6 protrudes upward from the upper surface of the foot pedal 101. The counterweight tube 6 and the suspension seat 21 are on the same vertical line. A counterweight ring 61 is provided around the counterweight tube 6 to form the center of gravity in the middle of the suspended platform 1. The counterweight ring 61 is sleeved and fixed around the counterweight tube 6. The counterweight ring 61 is an annular cone that gradually slopes downward from the top of the counterweight tube 6, thereby further ensuring that the suspended platform 1 is stable during use.
[0038] In this embodiment, the second adjustment mechanism 4 includes a balance arm 41 connected to the counterweight tube 6 via bearings. The balance arm 41 extends from the counterweight tube 6 towards the left and right ends of the suspended platform 1, respectively. The second adjustment mechanism 4 also includes counterweight blocks 42 fixed to the two extended ends of the balance arm 41. Since the center of the balance arm 41 is located at the center of the counterweight tube 6, and both ends of the balance arm 41 extend symmetrically from the center of the counterweight tube 6, it can be seen that the balance arm 41, as the bottom component of the suspended platform 1, forms a balance structure with the counterweight tube 6, further ensuring the stability of the suspended platform 1 during use.
[0039] In addition to stabilizing the suspended platform 1 through its mounting structure, the counterweight arm 41 can also change the position of the counterweight blocks 42 at both ends of the suspended platform 1 by rotating back and forth. When the suspended platform 1 also experiences severe left and right swaying due to the aforementioned winch problem, the left and right swaying amplitude of the suspended platform 1 can be reduced by changing the position of the counterweight blocks 42. When the steel wire rope 5 is pushed back and forth by the front "V" shaped fork 32 and the rear "V" shaped fork 32 to reduce the left and right swaying amplitude of the suspended platform 1, under the action of inertial force, the counterweight arm 41 will also drive the counterweight block 42 at the same side to swing forward or backward with the steel wire rope 5, and the left and right swaying amplitude of the suspended platform 1 will be rapidly reduced by its own weight.
[0040] In this embodiment, such as Figure 1 , Figure 2 As shown, both the left and right inclined tubes 31 include bent inclined portions 311 and vertical portions 312. The inclined portions 311 are connected to the hanging tube 22 and are located above the front and rear steel wire ropes 5. The inclined extension end of the inclined portion 311 extends to the left or right end of the suspended basket 1. The vertical portion 312 is the extension end of the inclined portion 311 and is perpendicular to the left or right end of the suspended basket 1 (the vertical portion 312 on the left inclined tube 31 is perpendicular to the inner side of the left end of the suspended basket 1, and the vertical portion 312 on the right inclined tube 31 is perpendicular to the inner side of the right end of the suspended basket 1). The construction personnel hold the vertical portion 312 for easy operation. At the same time, the inclined structure of the inclined portion 311 also leaves enough construction space for the suspended basket 1, making the structure reasonable.
[0041] In this embodiment, the support pipe 32 is welded to the vertical part 312. The "V"-shaped forks 321 at the front and rear ends of the support pipe 32 are horizontally arranged between the front and rear steel wire ropes 5. The "V"-shaped opening of the front "V"-shaped fork 321 faces the front steel wire rope 5, and the "V"-shaped opening of the rear "V"-shaped fork 321 faces the rear steel wire rope 5. The distance between the front and rear wire grooves 212 on the hanging seat 21 is less than the distance between the connection points of the front and rear ends of the front and rear steel wire ropes 5 respectively connected to the top of the hanging basket 1. When the “V”-shaped fork 321 pushes the wire rope 5 to swing back and forth, the force point of the wire rope 5 is far away from the wire groove 212 and slightly closer to the basket 1. The two “V”-shaped forks 321 at the same end are symmetrically positioned, with their “V”-shaped openings facing the front and rear wire ropes 5 respectively. The inclined part 311, which is connected to the vertical part 312, is located between the two wire ropes 5. Therefore, when operating through the vertical part 312, the vertical part 312 is equivalent to a lever, and the inclined part 311 is equivalent to an extension of the lever. The lifting pipe 22, which is far from the lever, serves as a rotation point located in the middle of the upper part of the basket 1. Therefore, when holding the vertical part 312 and pushing the two “V”-shaped forks 321 to push the two wire ropes 5 respectively, the operating force can be saved.
[0042] It is worth noting that during actual assembly, hanging plates are welded to both the outer wall of the hanging pipe 22 and the top surface of the hanging seat 21. A bending spring is connected between the hanging pipe 22 and the hanging seat 21 through the hanging plate, so that the hanging pipe 22 can automatically rotate back after rotation. When rotating, the support pipe 32 can automatically return to the position between the two wire ropes 5, and the suspended basket 1 automatically returns to a stable operating state.
[0043] In another implementation, such as Figures 4 to 9 As shown, a rotating wheel assembly 7 is provided at each of the left and right ends of the rear of the suspended basket 1. The rotating wheel assembly 7 includes a wheel frame 71 fixed on the suspended basket 1 and a brake wheel 72 connected to the wheel frame 71. The wheel frame 71 extends beyond the rear side of the suspended basket 1 and restricts the brake wheel 72 to extend beyond the rear side of the suspended basket 1.
[0044] When the suspended platform 1 is swung back and forth to reduce its protruding left and right swaying, the rear side of the suspended platform 1 may hit the exterior wall of the building. At this time, the brake wheel 72 will first contact the exterior wall and roll to avoid collision with the exterior wall and affect the construction quality.
[0045] In this embodiment, the counterweight 42 is an arc-shaped counterweight plate. The center of the arc of the counterweight 42 is concentric with the rotation center of the balance arm 41. When the suspended basket 1 is manually adjusted to swing backward, the counterweight 42 will follow the balance arm 41 to swing backward due to the deflection of the suspended basket 1. When it reaches the limiting shaft 103 on the rear side, the rotation stops. At this time, the end of the counterweight 42 will press against the brake lever 733. The inner end of the brake lever 733 will press the brake pad 734 against the rotation shaft of the brake wheel 72, so that the brake wheel 72 stops rolling. Since the brake wheel 72 stops rolling at this time, after the brake wheel 72 completes the rolling contact with the wall to form wall protection, it then stops abruptly to prevent the suspended basket 1 from swinging left and right under the rolling action. Thus, the technical effect of adjusting the left and right swaying of the suspended basket 1 by swinging back and forth is invalidated.
[0046] A limit stop 735 is welded onto the brake lever 733. A return spring 736 is provided between the limit stop 735 and the outer side of the hanging plate 731. The return spring 736 is sleeved on the brake lever 733. When the hanging basket 1 moves away from the wall in the opposite direction, the brake wheel 72 no longer contacts the wall. The return spring 736 releases its restoring force, which acts on the limit stop 735. The limit stop 735 pushes the brake lever 733 back in the opposite direction. The inner end of the brake lever 733 pulls the brake pad 734 back, and the brake wheel 72 returns to the rotating state. It waits for the next time the hanging basket 1 sways left and right, so that it can contact the wall again and protect the wall, thus completing the braking action.

This implementation scheme is only for the convenience of describing the scheme and for setting relative orientations with reference to the reference orientations. In reality, the specific orientations of each component are based on their actual installation and actual use, as well as the orientation descriptions that are customary to those skilled in the art.
