Description

Technical Field

[0001] This application relates to the technical field of lifting devices for steel structure processing, specifically a stable lifting device for steel structure processing. Background Technology

[0002] Steel structures are engineering structures made primarily of steel, formed through design, processing, and connection. They are widely used in construction, bridges, industrial equipment, and other fields. It is one of the most important structural types in modern engineering, characterized by high strength, light weight, rapid construction, and good environmental performance. Along with concrete and timber structures, it is considered one of the three major engineering structural systems.

[0003] During steel structure fabrication, lifting devices are used to elevate workers for assembly, welding, and other processing of the steel structures at higher positions. However, commonly used scissor lift platforms are generally single-layer platforms, allowing workers to work at only one height at a time. When assembling longitudinal steel structures, which may require simultaneous work at different heights, two lifting devices are needed, wasting resources and being inconvenient.

[0004] Therefore, this application provides a stable lifting device for steel structure processing to solve the above problems. Utility Model Content

[0005] This application provides a stable lifting device for steel structure processing, which aims to solve the problem mentioned in the background art that existing lifting platforms require multiple lifting devices to solve the problem when assembling longitudinal steel structures.

[0006] To achieve the above objectives, this application provides the following technical solution: a stable lifting device for steel structure processing, comprising a scissor lift frame, a lifting hydraulic push rod hinged to the middle of the scissor lift frame for driving the scissor lift frame to extend or retract, and a man-standing platform fixedly installed at the top of the scissor lift frame. A four-wheel drive moving seat is fixedly installed at the bottom of the scissor lift frame. A second-level platform is fixedly connected to the top of the man-standing platform via support columns. A manhole is provided on the second-level platform, and a ladder connecting to the manhole is fixedly connected to the man-standing platform. Thus, through the rigid connection design between the man-standing platform and the second-level platform, a single device can cover the needs of simultaneous vertical and horizontal construction of the longitudinal steel structure, replacing the traditional solution of two lifting devices, saving resources and improving convenience.

[0007] Preferably, the support column has four columns, which are located at the four corners of the top of the support column.

[0008] Preferably, both the standing platform and the second-floor platform are fixedly connected to fences on all four sides.

[0009] Preferably, foldable stabilizing mechanisms are symmetrically installed on both sides of the four-wheel drive mobile seat along its length.

[0010] Preferably, the stabilizing mechanism includes a hinge seat fixedly installed on the side of the four-wheel drive mobile seat, a folding support leg hinged to the hinge seat, a folding push rod hinged to the hinge seat with its movable end hinged to the folding support leg, and a fixing rod fixedly connected to the end of the folding support leg away from the hinge seat.

[0011] Preferably, the bottom end of the fixing rod has a pad.

[0012] Preferably, the wheels of the four-wheel drive mobile seat are Mecanum wheels.

[0013] This stable lifting device for steel structure processing, through the rigid connection design between the standing platform and the second-floor platform, enables a single device to cover the needs of synchronous construction of the longitudinal steel structure from top to bottom, replacing the traditional solution of two lifting devices, saving resources and improving convenience.

[0014] This steel structure processing stabilizing lifting device, after the folding outriggers are unfolded, expands the equipment's support area from the original "rectangular base" of the wheels to a "hexagonal base," increasing the number of support points in contact with the ground and increasing the contact area of ​​the pads. This effectively disperses the lifting platform and operating load, reduces the pressure on individual support points, and avoids tilting caused by localized soft ground. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Example 1

[0024] This embodiment provides a stable lifting device for steel structure processing, such as... Figures 1-2 As shown, the stable lifting device for steel structure processing includes a scissor lift frame 1, a lifting hydraulic push rod 11 hinged in the middle of the scissor lift frame 1 for driving the scissor lift frame 1 to extend or retract, and a standing platform 2 fixedly installed at the top of the scissor lift frame 1. A four-wheel drive moving seat 3 is fixedly installed at the bottom of the scissor lift frame 1. A second-level platform 22 is fixedly connected to the top of the standing platform 2 through a support column 21. A manhole 221 is opened on the second-level platform 22. A ladder 23 connecting to the manhole 221 is fixedly connected to the standing platform 2.

[0025] In use, the device is moved to the steel structure processing position via the four-wheel drive mobile seat 3, and precise positioning is achieved by utilizing the driving force and stability of the four-wheel drive. During lifting and adjustment, the lifting hydraulic push rod 11 is activated to push the scissor lifting frame 1 to extend, driving the standing platform 2 and the second-floor platform 22 to rise to the target height simultaneously. During layered operations, workers can perform low-level operations on the standing platform 2, or climb the ladder 23 through the manhole 221 to the second-floor platform 22 for high-level operations, achieving simultaneous vertical and horizontal construction of the longitudinal steel structure with a single piece of equipment. When the operation is completed, the lifting hydraulic push rod 11 is retracted, the scissor lifting frame 1 is closed, the device is lowered back to the low position, and then transferred to the next work position via the four-wheel drive mobile seat 3.

[0026] Specifically, the support column 21 has four columns, which are located at the four corners of the top of the support column 21 respectively; the standing platform 2 and the second-floor platform 22 are fixed into an integral structure by rigid connection, while leaving the central activity space.

[0027] It should be noted that both the standing platform 2 and the second-floor platform 22 are fixedly connected to the perimeter of the platform by railings 24. The railings 24 are fixed to the edge of the platform by welding or bolting to form a closed protective boundary. The railings 24 directly reduce the risk of working at height. In particular, when workers move between the second-floor platform 22 and the standing platform 2 by climbing ladder 23, the railings 24 provide lateral protection to avoid falls caused by shifting center of gravity or slippery ground.

[0028] Furthermore, the wheels 31 of the four-wheel drive mobile seat 3 are Mecanum wheels; by controlling the rotation speed and steering of the four wheels 31 using Mecanum wheels, the equipment can move in all directions in a plane. Steel structure processing workshops often have obstacles such as columns and equipment. The omnidirectional movement capability of Mecanum wheels allows the equipment to be accurately positioned in a limited space without repeatedly adjusting the vehicle's direction, thus shortening the movement time.

[0029] Example 2

[0030] Unlike Embodiment 1, since the scissor lift is generally a rectangular space, after the entire device is moved into place, it is supported by the four-wheel drive moving seat 3. However, the support points of the four wheels are also distributed in a rectangular shape, resulting in uneven distribution of the support points along the length direction, which poses a risk of side collapse. Therefore, foldable stabilizing mechanisms 4 are symmetrically installed on both sides of the four-wheel drive moving seat 3 along the length direction. The stabilizing mechanism 4 includes a hinge seat 41 fixedly installed on the side of the four-wheel drive moving seat 3, a folding support leg 42 hinged to the hinge seat 41, a folding push rod 43 hinged to the hinge seat 41 and whose movable end is hinged to the folding support leg 42, and a fixed rod 421 fixedly connected to the end of the folding support leg 42 away from the hinge seat 41. The bottom end of the fixed rod 421 has a pad 422.

[0031] When the folding push rod 43 is in the retracted state, the folding outrigger 42 is pulled close to the side of the four-wheel drive mobile seat 3. At this time, the stabilizing mechanism 4 does not occupy extra space, ensuring the flexibility of equipment movement. When the device is moved to the steel structure processing position, the folding push rod 43 starts to extend, pushing the folding outrigger 42 to rotate outward around the hinge seat 41 until the fixing rod 421 and the pad 422 at the end of the folding outrigger 42 contact the ground. At this time, the pad 422 of the stabilizing mechanism 4 on both sides and the original wheel 31 of the four-wheel drive mobile seat 3 together form a multi-point support, optimize the distribution of the support points, and reduce the risk of rollover.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
