Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a manned construction platform mounted on a steel truss. Background Technology

[0002] With the proliferation of super high-rise buildings, many of these structures feature extremely long cantilevered structures, posing significant challenges and safety risks to construction. In steel truss construction, the trusses are quite tall, requiring workers to perform welding and assembly work at heights. Furthermore, welding and assembly work must also be carried out on the trusses while they are being lifted onto the main structure.

[0003] Due to the hollow structure of steel trusses, there are no platforms between the trusses to provide working platforms for construction personnel. Therefore, during the construction of steel trusses, it is usually necessary to erect temporary auxiliary construction platforms to meet the needs of construction personnel for standing and temporary storage of construction parts or equipment. However, steel trusses are often quite long, while the length of temporary auxiliary construction platforms is limited. Therefore, when using temporary auxiliary construction platforms for construction, it is usually done segment by segment. This means that construction personnel often need to repeatedly disassemble and assemble the construction platforms to move them between different segments, which wastes a lot of manpower and time, thus presenting obvious shortcomings.

[0004] Therefore, we have made improvements and proposed a steel truss with a manned construction platform underneath. Summary of the Invention

[0005] The technical problem that this invention aims to solve is that the steel truss is long, and the construction of each section requires repeated disassembly and assembly of the construction platform to move it between different sections, which wastes manpower and time.

[0006] To achieve the above-mentioned objectives, the present invention provides a manned construction platform under a steel truss, comprising a steel truss, a fixing mechanism connected to the bottom of the steel truss, the fixing mechanism comprising two connecting blocks, a connecting rod and a lead screw installed at the bottom of the connecting blocks, a first motor installed at the outer end of the lead screw, a first pressure ring installed on one side of the connecting blocks, a second pressure ring provided on one side of the first pressure ring, a slider installed at the bottom of the second pressure ring, the slider being sleeved between the connecting rod and the lead screw, a connecting frame also connected to the bottom of the connecting blocks, a collar connected to the middle of the connecting frame, a slide rail fixedly connected to the collar, and a first electric push rod connected between the two connecting blocks, a connecting assembly mounted on the middle of the slide rail, and a moving platform connected to the connecting assembly.

[0007] As a further embodiment of the present invention, the connecting assembly includes a support frame, two winding machines are respectively installed on both sides of the steel truss, two sliding frames are symmetrically arranged on the upper end of the support frame, a steel cable is connected to the bottom of the sliding frame, the bottom of the steel cable is wound and connected to the winding machine, a roller is installed on the upper end of the sliding frame, the roller is clamped on both sides of the slide rail, and a third motor is connected to one end of the roller.

[0008] As a further embodiment of the present invention, a second motor is sleeved in the middle of the connecting block, and a rotating rod is connected to the upper end of the second motor. The rotating rod is cross-shaped, and the bottom surface of the rotating rod is provided with several anti-slip protrusions.

[0009] As a further embodiment of the present invention, both the first pressure ring and the second pressure ring are arc-shaped, and the sum of the central angles of the first pressure ring and the second pressure ring is greater than 180 degrees.

[0010] As a further embodiment of the present invention, the mobile platform includes a suspended platform with a notch in the middle. A first step and a second step are connected in a stepped manner inside the notch. T-blocks are provided on the edges of the suspended platform and the first step. T-grooves matching the T-blocks are provided on the sides of the first step and the second step. A fixing rod is installed inside the suspended platform. A second electric push rod is connected to both sides of the fixing rod and the first step, and the fixing rod and the second step.

[0011] As a further embodiment of the present invention, the suspended basket is provided with limiting blocks on both sides, the support frame is installed inside the limiting blocks, and the width of the support frame is the same as the width of the suspended basket.

[0012] As a further embodiment of the present invention, the bottom and sides of the suspended basket, the first step and the second step are all hollowed out.

[0013] As a further embodiment of the present invention, the slide rail is composed of two sets of circular steel columns, which are respectively arranged on both sides of the moving platform, and both ends of the two sets of circular steel columns are fixed by steel plates.

[0014] The steel truss-supported manned construction platform provided by this invention has the following advantages:

[0015] 1. By setting up two sets of symmetrical fixing mechanisms and fixing them to both ends of the steel truss, and erecting slide rails on the two sets of fixing mechanisms to form a track, the connecting components and the mobile platform are suspended and installed on the slide rails and move on the slide rails, so that the mobile platform can move flexibly along the direction of the steel truss, making it convenient for workers to ride the mobile platform to carry out construction on the steel truss.

[0016] 2. By installing a rotating rod on the connecting block, the rotating rod is driven by the second motor to rotate, causing the entire fixing mechanism to move along the steel truss, thereby adjusting the position of the device on the steel truss. After adjustment, the first and second pressure rings clamp the steel truss tightly, ensuring that the fixing mechanism is stably attached to the steel truss. During the adjustment process, it is not necessary to lower the workers to the ground. By controlling the two sets of fixing mechanisms to alternately adjust their specific positions on the steel truss, the displacement of the slide rail is achieved, which not only ensures the safety of the workers but also reduces the load on the device and facilitates the adjustment of the device's position along the steel truss.

[0017] 3. By setting a notch in the middle of the suspended platform, and installing the first and second steps in the notch, the first and second steps can be unfolded or retracted by extending and retracting the second electric push rod. The unfolded first and second steps form a step shape downwards, which can increase the depth of the mobile platform itself, provide different height differences inside the mobile platform, facilitate construction personnel to carry out construction in different positions, and avoid discomfort caused by workers bending over or looking up for a long time.

[0018] 4. By installing the connecting components and the mobile platform on the slide rail, and fixing both ends of the slide rail to different positions on the steel truss through the fixing mechanism, a temporary stable platform is provided for the construction of the mobile platform. However, since the steel truss is too long, the position of the moving fixing mechanism on the steel truss is adjusted to achieve segment-by-segment construction on the steel truss, saving manpower and time.

[0029] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0030] like Figures 1-8 As shown, this embodiment proposes a manned construction platform under a steel truss, including a steel truss 1. A fixing mechanism 2 is connected to the bottom of the steel truss 1. The fixing mechanism 2 includes two connecting blocks 21. A connecting rod 25 and a lead screw 26 are installed at the bottom of the connecting blocks 21. A first motor 27 is installed at the outer end of the lead screw 26. A first pressure ring 22 is installed on one side of the connecting blocks 21. A second pressure ring 23 is provided on one side of the first pressure ring 22. A slider 24 is installed at the bottom of the second pressure ring 23. The slider 24 is sleeved between the connecting rod 25 and the lead screw 26. A connecting frame 28 is also connected to the bottom of the connecting blocks 21. A collar 29 is connected to the middle of the connecting frame 28. A slide rail 3 is fixedly connected to the collar 29. A first electric push rod 210 is connected between the two connecting blocks 21. A connecting component 4 is installed in the middle of the slide rail 3. A mobile platform 5 is connected to the connecting component 4.

[0031] The connecting component 4 includes a support frame 41. Two winding machines 43 are installed on both sides of the steel truss 1. Two sliding frames 42 are symmetrically arranged on the upper end of the support frame 41. The bottom of the sliding frame 42 is connected to a steel cable 44. The bottom of the steel cable 44 is wound and connected to the winding machine 43. A roller 45 is installed on the upper end of the sliding frame 42. The roller 45 is clamped on both sides of the slide rail 3, and one end of the roller 45 is connected to a third motor 46. The support frame 41 and the sliding frame 42 are connected by the steel cable 44, so that the support frame 41 and the moving platform 5 can be vertically adjusted by the winding and unwinding of the winding machine 43, which also facilitates the up and down of construction personnel. The roller 45 is installed on the slide rail 3, and the third motor 46 drives the roller 45 to rotate, so that the connecting component 4 can move freely on the slide rail 3.

[0032] A second motor 213 is sleeved in the middle of the connecting block 21. A rotating rod 211 is connected to the upper end of the second motor 213. The rotating rod 211 is cross-shaped and has several anti-slip protrusions 212 on its bottom surface. The second motor 213 drives the rotating rod 211 to rotate. The anti-slip protrusions 212 on the bottom surface of the rotating rod 211 are used to contact and rub against the steel truss 1 to push the fixing mechanism 2 to slide on the steel truss 1, thereby adjusting the position of the two sets of fixing mechanisms 2.

[0033] Both the first pressure ring 22 and the second pressure ring 23 are arc-shaped, and the sum of the central angles of the first pressure ring 22 and the second pressure ring 23 is greater than 180 degrees. The first pressure ring 22 and the second pressure ring 23 clamp the bottom sides of the steel truss 1 respectively, so that the first pressure ring 22 and the second pressure ring 23 stably wrap and fix the steel truss 1, and prevent the fixing mechanism 2 from falling off the steel truss 1.

[0034] The mobile platform 5 includes a suspended platform 51. A notch is provided in the middle of the suspended platform 51. A first step 55 and a second step 56 are connected in a stepped manner inside the notch. T-blocks 54 are provided on the edges of the suspended platform 51 and the first step 55. T-slots 57 that match the T-blocks 54 are provided on the sides of the first step 55 and the second step 56. A fixing rod 52 is installed inside the suspended platform 51. The fixing rod 52 and the first step 55, as well as the second step 56, are connected to the first step 55 and the second step 56 on both sides. A step is formed between the suspended platform 51 and the first step 55 and the second step 56 that are flexibly connected at the bottom, creating a construction operation space at different heights. This avoids construction workers having to repeatedly bend over or look up for long periods of time during construction, ensuring the safety and comfort of the construction personnel.

[0035] Limiting blocks are provided on both sides of the suspended platform 51. The support frame 41 is installed inside the limiting blocks. The width of the support frame 41 is the same as the width of the suspended platform 51. The support frame 41 supports both ends of the suspended platform 51 and is fixedly connected to the suspended platform 51 to form a whole, so that the mobile platform 5 can move laterally or rise and fall longitudinally with the connecting component 4.

[0036] The bottom and sides of the suspended platform 51, the first step 55, and the second step 56 are all hollowed out. The hollowed-out design of the suspended platform 51, the first step 55, and the second step 56 can minimize their own load and avoid the inconvenience of operation caused by the overall weight of the moving platform 5 during the movement of the device.

[0037] The slide rail 3 consists of two sets of circular steel columns, which are respectively set on both sides of the moving platform 5. Both ends of the two sets of circular steel columns are fixed by steel plates. The slide rail 3 provides a smooth trajectory for the movement of the connecting component 4 and the moving platform 5, and avoids the connecting component 4 and the moving platform 5 being blocked or restricted by the nodes or steel pipes on the steel truss 1 when they move under the steel truss 1.

[0038] Specifically, the steel truss with a manned construction platform is used as follows: two sets of symmetrical fixing mechanisms 2 are fixed to both ends of the steel truss 1, and slide rails 3 are erected on the two sets of fixing mechanisms 2 to form a track. The connecting component 4 and the mobile platform 5 are suspended and installed on the slide rails 3 and move along the slide rails 3, allowing the mobile platform 5 to move flexibly along the direction of the steel truss 1, facilitating workers to carry out construction on the steel truss 1. The second motor 213 drives the rotating rod 211 to rotate, and the anti-slip protrusions 212 on the bottom of the rotating rod 211 contact friction with the steel truss 1 to push the fixing mechanism 2 to slide on the steel truss 1, so that the fixing mechanism 2 moves along the steel truss 1 as a whole. The positions of the two sets of fixing mechanisms 2 are adjusted, and after adjustment, the first pressure ring 22 and the second pressure ring 23 clamp the steel truss 1 to ensure that the fixing mechanism 2 is stably attached to the steel truss 1. The support frame 41 and the mobile platform 5 are lowered to the ground by the unwinding of the winding machine 43, and the construction workers can then proceed to the site. The mobile platform 5 is used to climb to the construction height. The first step 55 and the second step 56 are installed in the middle gap of the suspended platform 51. The first step 55 and the second step 56 are unfolded or retracted by the extension and retraction of the second electric push rod 53. The unfolded first step 55 and the second step 56 form a stepped shape downwards, providing different heights. Construction workers can carry out construction at different positions, avoiding the discomfort caused by workers bending over or looking up for a long time. By installing the connecting component 4 and the mobile platform 5 on the slide rail 3, and fixing the two ends of the slide rail 3 to different positions of the steel truss 1 by the fixing mechanism 2, a temporary stable platform is provided for the construction of the mobile platform 5. However, due to the length of the slide rail 3, the third motor 46 drives the roller 45 to rotate, so that the connecting component 4 can move freely on the slide rail 3 and move the position of the mobile platform 5 on the slide rail 3. This allows for segmented construction on the steel truss 1, saving manpower and time.
