Description

Technical Field

[0001] The embodiments of this utility model belong to the technical field of pipeline installation equipment, and more specifically, relate to a mobile lifting steam pipeline overhead construction safety platform. Background Technology

[0002] Steam pipelines, as critical infrastructure in the industrial sector, bear the core functions of heat transfer and power supply. Their construction efficiency and safety performance directly affect the stability of industrial production systems. However, traditional construction methods have revealed significant technical bottlenecks when dealing with complex operating environments.

[0003] In the overhead hoisting of steam pipelines, the high-altitude working environment and the suspended state of the pipelines pose dual risks. Traditional processes face three major technical challenges: First, the pipelines, when suspended for extended periods, are susceptible to swaying due to wind loads, leading to instability and the risk of overturning. Second, during manual pipe stabilization, accidental slippage of the pipeline can cause collisions, resulting in personnel injuries or fatalities. Third, existing construction platforms mostly employ fixed steel structure supports or simple scaffolding systems, which have the following inherent defects: height adjustment relies on mechanical transmission devices, horizontal displacement requires complete disassembly and assembly, and rapid response is not possible; adaptability to different pipe diameters and overhead heights is poor, requiring repeated use of lifting equipment for adjustments; and the platform surface lacks effective anti-roll devices, making the pipelines prone to unexpected displacement on the platform, significantly increasing the operational hazard factor.

[0004] The aforementioned technical deficiencies directly lead to extended construction periods and persistently high accident rates, failing to meet the demands of modern industrial pipeline engineering for efficient construction and inherent safety. Therefore, developing an intelligent construction platform with functions such as rapid deployment, precise positioning, and active anti-rollover features has become a key direction for overcoming traditional technical bottlenecks. Summary of the Invention

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1-3 As shown, this utility model provides a mobile lifting steam pipeline overhead construction safety platform, including an equipment base 1, a lifting mechanism, a lifting seat plate 3, a protective bracket 4, a plastic-coated steel wire mesh 5, and an arc-shaped bracket 6. The equipment base 1 is used to support and install other functional components. It has casters 8 at its bottom for easy movement of the platform to the construction site. The lifting mechanism includes multiple sets of lifting push rods 2, which are vertically oriented. Their bottoms are fixed to the top of the equipment base 1, and their tops are fixedly connected to the bottom of the lifting seat plate 3. The lifting mechanism uses multiple sets of lifting push rods 2 to simultaneously extend and retract, raising and lowering the lifting seat plate 3 to a specified height. Two sets of protective supports 4 are fixedly installed on the top of the lifting seat plate 3, symmetrically positioned on either side of the longitudinal center line. A plastic-coated wire mesh 5 is installed on top of the protective supports 4 to prevent personnel or objects from falling, ensuring operational safety. The arc-shaped bracket 6 is an arc-shaped tubular component with a downward indentation in the middle. Both ends are fixedly connected to the inner sides of the two sets of protective supports 4. This arc-shaped bracket 6 limits and supports the steam pipe, preventing it from rolling. This utility model's construction safety platform achieves mobility and flexible height adjustment. The arc-shaped bracket 6 prevents pipe slippage and facilitates fine-tuning of pipe positions, significantly reducing construction risks.

[0026] In this embodiment of the utility model, the equipment base 1 is made of steel plate, which increases its mass and can be used as a counterweight to enhance the stability of the platform. At the same time, it can enhance its own structural strength and make the functional components installed on its top more secure.

[0027] The movable wheels 8 are provided in four sets, which are fixedly installed at the four corners of the bottom of the equipment base 1. With the movable wheels 8, the operator can easily push the platform to the construction point.

[0028] The lifting mechanism is located on the top of the equipment base 1 and is used to quickly lift the lifting seat plate 3 to the corresponding working point to support the steam pipe. It includes multiple sets of lifting push rods 2. Further, the lifting push rod 2 is a hydraulic rod, with 3 sets on each side of the horizontal center line at the top of the equipment base 1, and the piston rod end of the lifting push rod 2 is fixedly connected to the lifting seat plate 3. Further, the lifting push rod 2 is also equipped with a displacement sensor and a pressure sensor, both of which are connected to the PLC control module. The PLC control module controls the hydraulic proportional valve according to the collected data. During the lifting operation, the PLC control module outputs the same initial current to the proportional valve, driving the hydraulic rods to rise simultaneously. During the rise, the output current of the proportional valve is adjusted according to the displacement and pressure values ​​collected by the displacement sensor and pressure sensor on each hydraulic rod to achieve synchronous lifting and ensure the stability of the lifting seat plate 3.

[0029] To ensure a more secure installation of the lifting mechanism and prevent it from shifting under force during lifting operations, a support frame 9 is provided on the top of the equipment base 1. The support frame 9 has a U-shaped structure, including two sets of vertical rods vertically installed on the top of the equipment base 1, and horizontal rods fixed at both ends to the top of the two sets of vertical rods. Limiting holes are opened at corresponding positions on the horizontal rods. The limiting holes are fitted onto the upper end of the lifting push rod 2 to prevent it from shifting under force during lifting operations.

[0030] To improve the stability of the construction safety platform during operation, a ground support mechanism is provided on the outer side of the equipment base 1. This ground support mechanism consists of four sets, symmetrically fixed on both sides of the equipment base 1. Each set includes a fixed base 12, a combined sleeve 13, a fixed clamping rod 14, and an adjusting screw. The fixed base 12 is fixedly mounted on the top of the equipment base 1, and the combined sleeve 13 is fixedly mounted on its outer side. The combined sleeve 13 is located on the outer side of the equipment base 1, vertically oriented, and has an inverted cylindrical structure. The fixed clamping rod 14 is slidably disposed within the combined sleeve 13 and can slide vertically along the combined sleeve 13. The adjusting screw is threaded to the top of the combined sleeve 13, and its bottom passes through the top of the combined sleeve 13 and is rotatably connected to the top of the fixed clamping rod 14. By turning the adjusting screw, the fixed clamping rod 14 slides downwards along the combined sleeve 13, thus contacting the ground and providing stable support, preventing the work platform from shaking, ensuring safe operating space for construction personnel, and bearing the transmission of construction loads.

[0031] The protective bracket 4 is used to install and fix the plastic-coated steel wire mesh 5. It has two sets, which are symmetrically arranged on both sides of the longitudinal center line of the lifting seat plate 3. It includes a grid frame and a support column. The grid frame is used to install and fix the plastic-coated steel wire mesh 5 and has a grid structure. The support column is vertically fixed on the top of the lifting seat plate 3. Its top is fixedly connected to the bottom of the grid frame to raise the height of the grid frame and provide a buffer distance for the plastic-coated steel wire mesh 5.

[0032] The PVC-coated steel wire mesh 5 is installed and fixed on the top of the protective bracket 4. It is made by coating a layer of plastic onto the surface of the steel wire mesh. This plastic coating separates the steel wire from air and water, effectively preventing the iron from oxidizing and rusting, thus extending the service life of the wire mesh and allowing it to be used for extended periods in harsh environments such as outdoors. This PVC-coated steel wire mesh 5 serves as a protective net to prevent people or objects from falling, ensuring operational safety.

[0033] The arc-shaped bracket 6 is used to limit and lift the steam pipe to prevent it from rolling. It is an arc-shaped tubular component with a downward indentation in the middle and its two ends are fixedly connected to the inner side of two sets of protective supports 4 respectively. Furthermore, three sets of the arc-shaped bracket 6 are arranged in parallel between the two sets of protective supports 4.

[0034] To facilitate the adjustment of the steam pipe installation angle and align the mounting holes on the flanges at both ends with other steam pipes for the next installation operation, the arc-shaped bracket 6 is also equipped with two or more sets of support pulleys 7. These support pulleys 7 are made of bearings, with their inner rings fixed to the arc-shaped bracket 6 and their outer rings in contact with the steam pipe. By rotating the steam pipe, the outer rings of the support pulleys 7 can rotate accordingly, reducing the friction between them and allowing operators to adjust the position of the pipe with great ease.

[0035] Preferably, the protective support 4 is also provided with a protective fence 11 on the outside, which can protect the operator from accidentally falling from the safety platform during operation.

[0036] When the construction safety platform of this utility model is in operation, the construction personnel can easily push the platform to the construction point using the movable wheels 8; turn the adjusting screw to make the fixing rod 14 slide down along the combined sleeve 13, thereby contacting the ground and providing stable support; place the steam pipe on the arc-shaped bracket 6; control multiple sets of lifting push rods 2 to simultaneously raise and lower the lifting seat plate 3 to the specified height; the operator climbs onto the protective support 4, and by rotating the steam pipe, completes the installation angle adjustment and installs and fixes this section of steam pipe; control multiple sets of lifting push rods 2 to simultaneously descend to the origin; turn the adjusting screw to make the fixing rod 14 retract into the combined sleeve 13; push the platform to move to the next construction point for operation.

[0037] This utility model's construction safety platform can be quickly deployed and flexibly adjusted. By integrating moving wheels and multiple sets of hydraulic lifting push rods into the platform, it supports rapid overall displacement and precise height adjustment, adapting to different overhead heights and pipe diameter requirements, without the need for repeated disassembly and assembly of lifting equipment.

[0038] This utility model's construction safety platform, through the use of an arc-shaped bracket and supporting pulleys, not only restricts the unintended rolling of pipelines but also allows for fine-tuning of the installation angle through low-friction rotation, significantly improving the safety and efficiency of high-altitude operations.

[0039] This utility model's construction safety platform uses displacement / pressure sensors and PLC closed-loop control to synchronously raise and lower multiple sets of hydraulic push rods, preventing platform tilting or pipe swaying and ensuring stable lifting in complex environments.

[0040] The construction safety platform of this utility model can be quickly grounded and fixed by a ground support mechanism to distribute the construction load; the counterweight design of the equipment base combined with the protective fence forms a double protection against overturning and falling.
