Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a steel structure node assembly high-altitude work platform. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Their structures are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Due to their light weight and simple construction, they are widely used in large factories, stadiums, super high-rise buildings, bridges and other fields.

[0003] In existing technologies, when constructing conventional steel structures, the working surface is usually high, and the actual work site is limited by the environment. Therefore, the assembly of steel structure nodes often employs high-altitude suspended operations, aerial work platforms, or ground-mounted scaffolding platforms. However, each of these methods has its drawbacks. High-altitude suspended operations typically require the simultaneous lifting of personnel and materials, violating safety regulations, endangering worker safety, and increasing the risk of operational errors, which negatively impacts the installation quality. Aerial work platforms are susceptible to limitations imposed by the actual site and working height, and require significant space, making them unsuitable for confined spaces. Ground-mounted scaffolding platforms are extremely cumbersome and time-consuming for steel structure projects with high working heights and numerous assembly nodes, hindering cost control and project timelines. Therefore, this invention provides a high-altitude work platform for assembling steel structure nodes to address these problems. Summary of the Invention

[0011] Furthermore, a second drive mechanism is fixedly installed on the outer side of the platform substrate. The output shaft of the second drive mechanism passes through the outer side of the platform substrate and a drive wheel is fixedly installed thereon.

[0012] Furthermore, the auxiliary support assembly includes an auxiliary plate fixed to the outside of the connecting rod, two auxiliary blocks fixed to the auxiliary plate near the platform substrate, a spherical slider fixed to the auxiliary blocks near the platform substrate, and an annular groove formed on the platform substrate near the auxiliary plate for the two spherical sliders to slide.

[0013] Furthermore, two square plates are fixed on the side of the platform base away from the guardrail, and two movable rods that penetrate the outer side of the corresponding square plate are fixed on the side of the U-shaped plate close to the adjacent square plate.

This steel structure node assembly aerial work platform, through the use of support components, allows the platform base plate to be easily moved to the construction site and can be dismantled before formal construction, facilitating the normal progress of subsequent construction work. Through the use of the limiting mechanism, the platform base plate and the outer side of the vertical steel can be limited to a certain extent by elastic limiting, which facilitates the stable operation of the lifting work.

Detailed Implementation

[0032] The technical solutions of the embodiments 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 7The present invention provides a technical solution: a steel structure node assembly high-altitude work platform, including a platform base plate 1 located on the outside of the vertical steel, three interconnected guardrails 201 fixedly installed on one side of the platform base plate 1, a guard door 202 hinged to the outside of the right guardrail 201 and connected to the outside of the left guardrail 201 by a pin, four support members 3 detachably installed on the other side of the platform base plate 1, a support sleeve 4 sleeved on the end of the vertical steel, a lifting mechanism 500 connected to the outside of the support sleeve 4 by a steel cable installed on the outside of the platform base plate 1, a limiting mechanism 600 that can limit the position with the vertical steel installed on the outside of the platform base plate 1, and a positioning mechanism 700 that can clamp the horizontal steel installed on the outside of the platform base plate 1;

[0034] In the above embodiment, the platform base plate 1 can be easily moved to the construction site by using the support member 3, and can be dismantled before formal construction to facilitate the normal progress of subsequent construction work. The limiting mechanism 600 can limit the platform base plate 1 to a certain extent with the outside of the vertical steel by means of elastic limiting. The lifting mechanism 500 can work with the limiting mechanism 600 to make the platform base plate 1 stably lifted on the outside of the vertical steel, so as to complete the work of changing the construction height without disassembling and reinstalling. The positioning mechanism 700 can clamp the two adjacent horizontal steels after reaching the construction height, so that the platform base plate 1 can remain stable under the positioning action of the positioning mechanism 700.

[0035] It should be noted that the support member 3 includes a column connected to the outside of the platform base plate 1 by bolts and an industrial wheel fixed to the other end of the column. The bolt connection makes it easy to assemble and disassemble the column, so that the platform base plate 1 can move by the column and the industrial wheel. When the limiting mechanism 600 is on the side of the platform base plate 1 away from the guardrail 201, the four support members 3 are located outside the limiting mechanism 600, so that the limiting mechanism 600 will not affect the assembly and disassembly of the support members 3.

[0036] In this embodiment, the lifting mechanism 500 is a structure used to raise or lower the platform to a certain height.

[0037] like Figure 1 and Figure 2As shown, the lifting mechanism 500 includes a reducer 501 fixedly installed on the outside of the platform base plate 1, a first drive mechanism 502 whose output shaft is connected to the input end of the reducer 501, a drive bevel gear 503 fixedly installed on the output shaft of the reducer 501, two support seats 504 fixedly installed on the outside of the platform base plate 1, a support rod 505 passing through and rotatably connected to the inner side of the corresponding support seat 504 through a bearing, a driven bevel gear 506 fixedly installed on the support rod 505 near one end of the drive bevel gear 503, a take-up roller 507 fixedly installed on the other end of the support rod 505, two fixing plates 508 respectively fixed on the right side and the outside of the top guardrail 201, a wire tube 509 passing through and fixed on the fixing plate 508 near the side of the corresponding take-up roller 507, and an equipment box 510 fixed on the outside of the platform base plate 1 and located outside the reducer 501.

[0038] It should be noted that one side of the support sleeve 4 is open, and this side can be used for insertion of the vertical steel, so that the support sleeve 4 can be stably fitted onto the end of the vertical steel. The end of the steel cable is detachably connected to the outside of the support sleeve 4, and the other end of the steel cable is detachably connected to the outside of the corresponding take-up roller 507. Specifically, the end of the steel cable is connected to the outside of the support sleeve 4 by bolts or other connectors. The outer surface of the take-up roller 507 has an installation hole for the steel cable to pass through. The other end of the steel cable passes through the installation hole and is connected to the take-up roller 507 by bolts or other connectors. At the same time, other connection methods that can stably fix the steel cable can also be used to connect and fix it.

[0039] Furthermore, the outer side of the active bevel gear 503 meshes with the outer side of the two driven bevel gears 506 respectively. The other end of the support rod 505 passes through the side of the corresponding guardrail 201 near the reducer 501 and extends to the outer side of the guardrail 201. The first drive mechanism 502 can be a servo motor, so that the first drive mechanism 502 can drive the active bevel gear 503 to rotate through the reducer 501, thereby causing the two driven bevel gears 506 to rotate. This allows the support rod 505 to drive the corresponding take-up roller 507 to rotate under the support of the support seat 504, thus realizing the functions of unwinding and rewinding.

[0040] In addition, both sides of the guide tube 509 are open, and the inner side of the guide tube 509 is tapered. The inner diameter of the guide tube 509 on the side closer to the take-up roller 507 is smaller than the inner diameter on the side farther away from the take-up roller 507. The position of the guide tube 509 corresponds to the position of the corresponding take-up roller 507. The opening on the side of the guide tube 509 away from the take-up roller 507 has rounded corners, so that the steel cable can be passed through the inner side of the guide tube 509. This allows the guide tube 509 to guide the steel cable, and the rounded corners also protect the surface of the steel cable.

[0041] In this embodiment, the limiting mechanism 600 is a structure used to limit the position of the platform during the lifting process so that it can maintain a stable lifting state.

[0042] like Figure 3 , Figure 4 and Figure 6 As shown, the limiting mechanism 600 includes a connecting rod 603 rotatably connected to the side of the platform base plate 1 away from the guardrail 201 via a bearing, an auxiliary support assembly fixedly installed between the connecting rod 603 and the outer side of the platform base plate 1, a mounting plate 606 fixed to the outer side of the connecting rod 603, a drive box 607 fixed to the side of the mounting plate 606 away from the platform base plate 1, an extension box 608 fixed to the outer side of the drive box 607, a first hydraulic cylinder 609 fixedly installed inside the extension box 608, a linear plate 610 fixedly installed on the output shaft of the first hydraulic cylinder 609, two racks 611 fixed to the side of the linear plate 610 away from the first hydraulic cylinder 609, and a fixed rack on the other side of the linear plate 610. Two linear rods 612, two round rods 613 rotatably connected to the inside of the drive box 607 via bearings, an external gear 614 fixedly installed on the outside of the round rods 613, a connecting plate 615 fixed on the outside of the round rods 613, a bonding plate 616 fixed on the side of the connecting plate 615 away from the linear plate 610, a sliding rod 617 fixed on the side of the bonding plate 616 away from the drive box 607, a sleeve 618 slidably connected to the outside of the sliding rod 617, four side rods 619 respectively fixed on the outside of the two sleeves 618, a limiting roller 620 fixedly installed on the other end of the side rods 619, and a shock absorber 621 fixedly installed between the outside of the side rods 619 and the outside of the corresponding bonding plate 616.

[0043] It should be noted that a second drive mechanism 601 is fixedly installed on the outer side of the platform base plate 1. The output shaft of the second drive mechanism 601 passes through the outer side of the platform base plate 1 and a drive wheel 602 is fixedly installed thereon. A driven wheel 604 that can mesh with the outer side of the drive wheel 602 is fixedly installed on the outer side of the connecting rod 603, so that the drive wheel 602 can drive the driven wheel 604 to rotate, thereby allowing the connecting rod 603 to rotate. The second drive mechanism 601 can be a servo motor.

[0044] In addition, such as Figure 7As shown, the auxiliary support assembly includes an auxiliary plate 6051 fixed to the outside of the connecting rod 603, two auxiliary blocks 6052 fixed to the auxiliary plate 6051 near the platform substrate 1, a spherical slider 6053 fixed to the auxiliary block 6052 near the platform substrate 1, and an annular groove 6054 formed on the platform substrate 1 near the auxiliary plate 6051 for the two spherical sliders 6053 to slide. The auxiliary plate 6051 is located between the driven wheel 604 and the opposite side of the platform substrate 1. The inner side of the annular groove 6054 covers two-thirds of the outer side of the spherical slider 6053, so that the annular groove 6054 can support the spherical slider 6053. Thus, the auxiliary support assembly can provide auxiliary support for the connecting rod 603.

[0045] Meanwhile, the output shaft of the first hydraulic cylinder 609 passes through the outside of the drive box 607, the linear plate 610 is located inside the drive box 607, and the end of the linear rod 612 passes through the inside of the drive box 607, so that the first hydraulic cylinder 609 can push the linear plate 610 to move linearly under the limiting action of the two linear rods 612.

[0046] Furthermore, the two racks 611 are symmetrically distributed from left to right, and the external gear 614 is located between the two racks 611 on opposite sides. The outer sides of the racks 611 and the corresponding external gears 614 mesh with each other. The outer side of the external gears 614 is fixedly connected to the side of the adjacent bonding plate 616 near the first hydraulic cylinder 609. The side of the drive box 607 away from the first hydraulic cylinder 609 is open, so that the racks 611 can drive the corresponding external gears 614 to rotate. During the rotation of the external gears 614, the bonding plate 616 can be driven to rotate. A buffer pad that can abut against the outer side of the drive box 607 is bonded to the outer side of the bonding plate 616. The buffer pad can be a rubber pad, which can play a buffering role and achieve the anti-collision effect.

[0047] It should also be noted that the end of the sliding rod 617 is fixed with a limiting plate to limit the sleeve 618. The limiting roller 620 includes a straight plate and two symmetrical plates fixed to the side of the straight plate away from the sliding rod 617, and a roller rotatably connected between the opposite sides of the two symmetrical plates through bearings. The outer side of the limiting roller 620 can abut against the outer side of the vertical steel, so that the limiting roller 620 can play a limiting role. At the same time, it can roll relative to each other during the lifting or lowering process, without affecting the height adjustment. The shock absorber 621 is composed of a damping spring and a damper, which can play a shock absorption role for the vibration of the side rod 619, so that the limiting roller 620 can stably play a positioning role.

[0048] In this embodiment, the positioning mechanism 700 is a structure used for height positioning of the platform.

[0049] like Figure 1 and Figure 5 As shown, the positioning mechanism 700 includes two second hydraulic cylinders 701 fixedly installed on the outside of the platform base plate 1, a U-shaped plate 702 fixedly installed on the output shaft of the second hydraulic cylinders 701, a limiting slide rod 703 fixed on the inside of the U-shaped plate 702, a buffer spring 704 sleeved on the outside of the limiting slide rod 703, a limiting cylinder 705 slidably connected to the outside of the limiting slide rod 703 and fixedly connected to the end of the buffer spring 704, a push rod 706 fixed on the side of the limiting cylinder 705 away from the platform base plate 1, and a U-shaped clamp 707 fixed on the side of the push rod 706 away from the platform base plate 1.

[0050] It should be noted that two square plates 708 are fixed on the side of the platform base plate 1 away from the guardrail 201. Two movable rods 709 are fixed on the side of the U-shaped plate 702 close to the adjacent square plate 708, penetrating the outer side of the corresponding square plate 708. The output shaft of the second hydraulic cylinder 701 penetrates the outer side of the corresponding guardrail 201, so that the U-shaped plate 702 can move normally.

[0051] In addition, the limiting slide bar 703 is square with rounded corners, which allows the limiting slide cylinder 705 to slide stably on the outside of the limiting slide bar 703. The other end of the buffer spring 704 is fixedly connected to the inner side of the corresponding U-shaped plate 702, so that the limiting slide cylinder 705 can push the buffer spring 704 to compress stably during the movement. The buffer spring 704 is different from a conventional spring under force. The buffer spring 704 has a fast compression speed but a slow rebound speed, which can alleviate the impact force in some situations where it is necessary to reduce the impact force of objects falling.

[0052] Meanwhile, the side of the U-shaped clamp 707 away from the push rod 706 is open, allowing the U-shaped clamp 707 to be inserted into the outside of the horizontal steel. Specifically, during the construction of the steel structure, a vertical steel is usually used as the main support, and then two horizontal steels at a 90-degree angle are connected and assembled to complete the assembly of the vertical steel on one side of the steel structure.

[0053] The working principle of the above embodiments is as follows:

[0054] (1) When using this platform for steel structure construction, the platform base plate 1 is pushed to the construction site by the support member 3, and the support sleeve 4 is fitted onto the end of the vertical steel so that the support sleeve 4 can provide tensile support for the platform base plate 1 with steel cables. The four support members 3 are removed to suspend the platform base plate 1. The second drive mechanism 601 is started to drive the drive wheel 602 to rotate, which causes the driven wheel 604 to rotate and the connecting rod 603 to rotate. This causes the mounting plate 606 to drive the drive box 607 to rotate to the outside of the platform base plate 1. At this time, the two bonding plates 616 are located on both sides of the vertical steel. Start The first hydraulic cylinder 609 drives the linear plate 610 to move linearly under the action of the two linear rods 612, and drives the corresponding external gear 614 to rotate through the rack 611, thereby causing the connecting plate 615 to drive the bonding plate 616 to rotate towards the side closer to the vertical steel. At the same time, the limiting roller 620 abuts against the outer side of the vertical steel. Under the action of the shock absorber 621, the limiting roller 620 can play a shock-absorbing and buffering role during the movement, so that the limiting roller 620 can play a continuous and stable limiting role, thereby allowing the platform base plate 1 to be limited to the outer side of the vertical steel under the action of the four limiting rollers 620.

[0055] (2) Start the first drive mechanism 502, which drives the active bevel gear 503 to rotate via the reducer 501, causing the two driven bevel gears 506 to rotate. The support rod 505 then drives the take-up roller 507 to take up the cable, allowing the steel cable to continuously wind around the outside of the take-up roller 507, thus lifting the platform base plate 1. When the U-shaped clamp 707 aligns with the adjacent horizontal steel, stop lifting. Start the second hydraulic cylinder 701, pushing the U-shaped plate 702 to move towards the adjacent horizontal steel, clamping it on the outside of the horizontal steel to achieve clamping and positioning. This allows the platform base plate 1 to remain stable under the dual limiting effect of the steel cable and the U-shaped plate 702. When further lifting is needed after the current height construction is completed, start the first drive mechanism 502, which drives the active bevel gear 503 to rotate via the reducer 501, causing the two driven bevel gears 506 to rotate, allowing the take-up roller 507 to wind around the cable. The coiling action enables the lifting motion, while the position of the U-shaped clamp 707 remains unchanged. During the lifting process, the U-shaped clamp 707 moves linearly away from the platform base plate 1 under the sliding action between the limiting slide cylinder 705 and the limiting slide rod 703, pushing the buffer spring 704 to compress. When the platform base plate 1 rises to a higher working position, it stops. The second hydraulic cylinder 701 is activated, causing the U-shaped clamp 707 to move away from the corresponding horizontal steel. Under the elastic recovery action of the buffer spring 704, the limiting slide cylinder 705 is pushed to move closer to the platform base plate 1, allowing the U-shaped clamp 707 to automatically move to the height of the next horizontal steel. The second hydraulic cylinder 701 is then activated, allowing the U-shaped clamp 707 to clamp onto the outside of the horizontal steel, and construction work can continue at the current height. This process can be repeated to easily change the assembly height, making the construction work of the steel structure convenient and efficient.

[0056] Compared with existing technologies, this steel structure node assembly aerial work platform, through the use of support component 3, allows the platform base plate 1 to be easily moved to the construction site and can be dismantled before formal construction, facilitating the normal progress of subsequent construction work. The use of limiting mechanism 600 allows for a certain degree of restriction between the platform base plate 1 and the outer side of the vertical steel through elastic limiting, facilitating stable lifting operations. The use of lifting mechanism 500, in conjunction with limiting mechanism 600, allows the platform base plate 1 to be stably lifted on the outer side of the vertical steel, enabling changes in construction height without disassembly and reinstallation. The use of positioning mechanism 700 clamps two adjacent horizontal steel beams after reaching the construction height, ensuring the platform base plate 1 remains stable under the positioning action of positioning mechanism 700. This allows construction workers to safely perform node assembly operations. It achieves control over the actual erection space while facilitating stable adjustments based on the erection height, meeting the operational needs within confined spaces. This solves the problem in existing technologies where conventional steel structure construction operations are easily affected by site conditions and erection height, hindering efficient construction work.
