Description

Technical Field

[0001] This invention relates to a multifunctional safe construction platform and method for low-voltage transmission line foundation construction, belonging to the field of safety facilities for power line foundation construction. Background Technology

[0002] The construction of power transmission lines is characterized by numerous sites, wide coverage, long distances, tight schedules, and short effective construction periods. Due to the large number of foundations, their linear distribution, and wide geographical span, traditional power transmission line foundation construction typically employs two methods: large-scale excavation and segmented excavation. Large-scale excavation presents greater challenges for safety management, often involving multiple construction teams with varying skill levels, making safety management difficult. Furthermore, the dispersed nature of the construction sites further complicates on-site safety control.

[0003] Currently, there are no dedicated construction safety platforms for the foundation construction of the line. On-site, the original steel scaffolding is used to fix the foundation formwork, and temporary planks are erected as construction platforms for workers to carry out on-site concrete pouring, vibration and other operations. Construction workers are at risk of falling into the foundation pit. At the same time, because the temporary plank construction platform is connected to the formwork fixing system, the formwork will vibrate during concrete pouring and vibration, which increases the difficulty of controlling the key indicators of the foundation.

[0004] Therefore, there is an urgent need to propose a multi-functional safe construction platform and method for low-voltage transmission line foundation construction to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to address the problems of traditional power line foundation construction, which lacks dedicated safety platforms and facilities. On-site construction typically relies on primitive steel scaffolding to fix the foundation formwork, leading to significant challenges in safety management. Multiple construction teams often work simultaneously, with varying skill levels among personnel, and the construction sites are often dispersed, making on-site safety control relatively difficult. A brief overview of this invention is provided below to offer a basic understanding of certain aspects of the invention. It should be understood that this overview is not an exhaustive summary of the invention. It is not intended to identify key or essential parts of the invention, nor is it intended to limit the scope of the invention.

[0006] The technical solution of this invention:

[0007] Option 1: A multi-functional safety construction platform for low-voltage transmission line foundation construction, comprising a towable low-chassis trailer platform, a power generation and energy storage unit, a concrete vibration unit, a lighting unit, telescopic outriggers, and a foldable safety platform ramp unit. Telescopic outriggers are installed at the four corners of the bottom of the towable low-chassis trailer platform. The power generation and energy storage unit, the concrete vibration unit, and the lighting unit are installed on the towable low-chassis trailer platform. Foldable safety platform ramp units are installed on the left and right sides of the towable low-chassis trailer platform.

[0008] Preferably, the towable low-chassis trailer platform is equipped with wheels at the four corners of its bottom.

[0009] Preferably, the foldable safety platform ramp unit includes a foldable ramp and a safety barrier. When the foldable ramp is unfolded, the safety barrier is fixedly installed on both sides of the foldable ramp.

[0010] Preferably, the towable low-chassis trailer platform is an H-shaped platform, with telescopic outriggers installed at the four corners of the H-shaped platform. Each telescopic outrigger includes a hydraulic cylinder and a support block. The hydraulic cylinder is fixedly installed at the four corners of the H-shaped platform, with its output end pointing vertically downwards and equipped with a support block.

[0011] Preferably, the power generation and energy storage unit includes a generator and an emergency DC power supply, which are electrically connected to the concrete vibration unit and the lighting unit, respectively.

[0012] Preferably, the concrete vibration unit includes a motor-integrated concrete vibrator and a mobile power supply, wherein the motor-integrated concrete vibrator is electrically connected to the mobile power supply.

[0013] Preferably, the towable low-chassis trailer platform is also equipped with a concrete pumping unit, which includes a concrete collection hopper, a standard concrete pump, a concrete pumping pipeline, a concrete pipeline rocker arm, and a concrete pipeline unloading port. The standard concrete pump is connected inside the concrete collection hopper, and the concrete pumping pipeline is installed on the concrete pipeline rocker arm. One end of the concrete pumping pipeline is connected to the concrete collection hopper through the standard concrete pump, and the other end of the concrete pumping pipeline is the concrete pipeline unloading port.

[0014] Option 2, a multi-functional and safe construction method for low-voltage transmission line foundations, is based on Option 1 and includes:

[0015] Step 1: Activate the telescopic outriggers to the retracted state, so that the wheels installed on the bottom of the towable low chassis trailer platform are on the ground. Use a construction vehicle to pull the towable low chassis trailer platform to the working pit location directly above the construction site of the line tower foundation.

[0016] Step 2: Activate the telescopic outriggers and extend them until the bottom of the outriggers touches the ground and the wheels are off the ground. Adjust the towable low-chassis trailer platform to be stable, ensuring that the platform plane is parallel to the ground and the wheel track exceeds the outer edge of the working pit by more than 1 meter. This completes the positioning of the towable low-chassis trailer platform.

[0017] Step 3: Unfold the foldable safety platform ramp units on both sides of the towable low chassis trailer platform and securely fix both ends of the foldable ramps so that the towable low chassis trailer platform and the foldable safety platform ramp units together form a cross passage platform directly above the working pit.

[0018] Step 4: The construction personnel operate the power generation and energy storage unit to provide reliable power output for the work, and at the same time connect the concrete vibration unit, lighting unit and concrete pumping unit to be in preparation for work.

[0019] Step 5: When pouring foundation concrete in the working pit, construction workers use vehicles to transport concrete to the concrete collection hopper of the concrete pumping unit. The construction workers operate the standard concrete pump and the concrete pipeline rocker arm to inject the concrete into the formwork of the line tower foundation leg in the working pit through the concrete pipeline unloading port. At the same time, the construction workers operate the concrete vibration unit to vibrate synchronously to ensure the quality of concrete pouring. The lighting unit provides lighting.

[0020] Step 6: After the concrete construction of the line tower foundation is completed and the key parameters are qualified, activate the telescopic outriggers to retract, so that the traveling wheels installed at the bottom of the towable low chassis trailer platform are on the ground and off the ground. Use a construction vehicle to pull the towable low chassis trailer platform directly above the working pit of the next line tower foundation construction site to complete one construction cycle.

[0021] The present invention has the following beneficial effects:

[0022] 1. The combination of the walking wheels and retractable telescopic outriggers of the present invention allows the platform to be quickly towed to different foundation pit locations by construction vehicles during transportation, without the need for complex disassembly or assembly. The telescopic outriggers' retraction mechanism, combined with the lightweight and compact structure of the trailer platform, enables "ready to use immediately upon stopping" at the construction site, significantly shortening equipment relocation time and adapting to the needs of continuous operation in multiple foundation pits.

[0023] 2. The power generation and energy storage unit of the present invention can autonomously supply power at the construction site of transmission lines in remote areas or where the power grid coverage is insufficient, avoiding construction delays caused by power outages. At the same time, it provides a stable power supply for units such as concrete vibration, pumping, and lighting, reducing reliance on external cables, reducing the risk of leakage, and complying with the safety specifications for power construction.

[0024] 3. The coordinated operation of the concrete collection hopper, pumping pipeline rocker arm, and vibration unit of the present invention achieves seamless connection of concrete "transportation-pumping-vibration", reduces manual handling and secondary operations, reduces labor intensity, and at the same time, through the synchronous operation of concrete pipeline unloading port and vibration inside the formwork, avoids concrete segregation, ensures the compactness of foundation pouring, and improves construction quality.

[0025] 4. The two folding ramps of the present invention form a cross platform after unfolding, covering more than 1 meter beyond the pit, expanding the working area and preventing the risk of personnel or materials falling. After the telescopic outriggers are extended, the trailer platform is removed from the ground. The platform plane is parallel to the ground and the force is evenly distributed, avoiding overturning accidents caused by uneven ground or pit collapse.

[0026] 5. The trailer platform of the present invention can be reused for the construction of multiple tower foundations, reducing the number of special equipment to be purchased and reducing the fixed asset investment of construction companies. The steps from positioning and power supply to pouring are all carried out according to a unified standard, reducing human error, facilitating quality control and personnel training, and meeting the requirements of standardized management of power construction.

[0027] 6. The lighting equipment of the present invention covers the foundation pit and operating area, ensuring construction safety and efficiency at night or in low-light environments, avoiding the risk of misoperation caused by insufficient lighting. At the same time, the platform structure is stable and the power is self-sufficient, which can maintain the continuity of foundation construction under complex terrain or bad weather conditions and shorten the project cycle.

[0028] 7. This invention reduces manual labor by using mechanized and automated equipment, such as pumping and vibration units, thereby reducing the probability of personnel being exposed to risks such as pit collapse and mechanical injury. Its comprehensive advantages in efficiency, safety, economy and standardization make it suitable for the modern management needs of low-voltage transmission line foundation construction.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0038] The connections mentioned in this invention are divided into fixed connections and detachable connections. Fixed connections, also known as non-detachable connections, include but are not limited to conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include but are not limited to conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0039] Specific implementation method one: Combining Figures 1-7 This embodiment describes a multi-functional safe construction platform for low-voltage transmission line foundation construction, comprising a towable low-chassis trailer platform 1, a power generation and energy storage unit 2, a concrete vibration unit 3, a lighting unit 4, telescopic outriggers 5, and a foldable safety platform plank unit 6. Telescopic outriggers 5 are installed at the four corners of the bottom of the towable low-chassis trailer platform 1. The power generation and energy storage unit 2, the concrete vibration unit 3, and the lighting unit 4 are installed on the towable low-chassis trailer platform 1. Foldable safety platform plank units 6 are installed on the left and right sides of the towable low-chassis trailer platform 1.

[0040] The towable low-chassis trailer platform 1 is equipped with four wheels 7 at the bottom corners.

[0041] The foldable safety platform ramp unit 6 includes a foldable ramp 61 and a safety barrier 62. When the foldable ramp 61 is unfolded, the safety barrier 62 is fixedly installed on both sides of the foldable ramp 61.

[0042] The foldable ramp 61 is composed of multiple connecting plates 611 hinged sequentially. Both ends of the foldable ramp 61 are fixedly connected to the low-chassis trailer platform 1 and the area near the outer top of the working pit, respectively. Adjacent connecting plates 611 are arranged with alternating forward and backward hinges. A stop block 612 is provided above one end of each connecting plate 611, and a slot 613 is provided below the other end of each connecting plate 611. When unfolded, as... Figure 3 and 4 As shown, two adjacent, alternating front and back connecting plates 611 unfold. The stop block 612 at the front end of the latter connecting plate 611 engages with the slot 613 of the former connecting plate 611, forming a self-locking mechanism. This achieves a limiting function, forcing the unfolded connecting plates 611 to tend towards a horizontal position, preventing local sagging, and ensuring the stability of personnel passage and equipment placement. Simultaneously, the stop block 612 also has mounting holes. The safety barrier 62 is a split type, with its bottom detachably installed into the mounting holes as needed. The folding ramp 61 has a compact volume after folding, as shown... Figure 5 As shown, this design reduces the risk of ramps extending outwards when the trailer platform is moved, while also reducing disassembly and assembly steps, improving relocation efficiency, and balancing safety, convenience, and structural reliability.

[0043] The towable low-chassis trailer platform 1 is an H-shaped platform. The four corners of the H-shaped platform are telescopic outriggers. The telescopic outriggers can be telescopic outrigger structures with built-in hydraulic cylinders, which can extend and retract to adjust the wheel track of the walking wheels 7. When used as a trailer, the telescopic outriggers extend and retract to keep the walking wheels 7 at the normal wheel track. After arriving at the construction site of the road foundation, the length of the telescopic outriggers can be adjusted to adjust the wheel track, ensuring that the wheel track of the walking wheels 7 exceeds the outer edge of the foundation pit by more than 1 meter. The adjusted towable low-chassis trailer platform 1 is placed on the foundation pit to be constructed by traction power. Telescopic outriggers 5 are installed on the telescopic outriggers at the four corners of the H-shaped platform. The telescopic outriggers 5 include hydraulic cylinders 51 and support blocks 52. The hydraulic cylinders 51 are fixedly installed on the four corners of the H-shaped platform. The output end of the hydraulic cylinder 51 is vertically downward and is equipped with support blocks 52.

[0044] The power generation and energy storage unit 2 includes a generator and an emergency DC power supply, which are electrically connected to the concrete vibration unit 3 and the lighting unit 4, respectively. The generator can be a diesel generator and a set of safety distribution boxes to provide a reliable power supply for the platform operation.

[0045] The lighting unit 4 consists of several portable lighting lamps and their corresponding lighting circuit systems.

[0046] The concrete vibration unit 3 includes a motor-mounted concrete vibrator and a mobile power supply, wherein the motor-mounted concrete vibrator is electrically connected to the mobile power supply.

[0047] The towable low-chassis trailer platform 1 is also equipped with a concrete pumping unit 8. The concrete pumping unit includes a concrete collection hopper 81, a standard concrete pump, a concrete pumping pipeline, a concrete pipeline rocker arm 82, and a concrete pipeline unloading port. The standard concrete pump is connected inside the concrete collection hopper 81. The concrete pumping pipeline is installed on the concrete pipeline rocker arm 82. One end of the concrete pumping pipeline is connected to the concrete collection hopper 81 through the standard concrete pump, and the other end of the concrete pumping pipeline is the concrete pipeline unloading port. The concrete pipeline rocker arm 82 is a swinging robotic arm of the prior art, which can clamp the concrete pumping pipeline and make the concrete pipeline unloading port of the concrete pumping pipeline face different directions.

[0048] Specific Implementation Method Two: Combining Figures 1-7 This embodiment describes a multi-functional safe construction method for low-voltage transmission line foundation construction, which is based on the multi-functional safe construction platform for low-voltage transmission line foundation construction described in Specific Embodiment 1, and includes:

[0049] Step 1: Activate the telescopic outriggers 5 to the retracted state, so that the traveling wheels 7 installed at the bottom of the towable low chassis trailer platform 1 touch the ground. Use a construction vehicle to pull the towable low chassis trailer platform 1 to the location directly above the working pit at the construction site of the line tower foundation.

[0050] Step 2: Activate the telescopic outrigger 5 and extend it until the bottom of the telescopic outrigger 5 touches the ground and the traveling wheels 7 are off the ground. Adjust the towable low chassis trailer platform 1 to a stable position, ensuring that the platform plane is parallel to the ground and that the wheel track of the traveling wheels 7 exceeds the outer edge of the working pit by more than 1 meter. This completes the positioning of the towable low chassis trailer platform 1.

[0051] Step 3: Unfold the foldable safety platform ramp units 6 on both sides of the towable low-chassis trailer platform 1, and securely fix both ends of the foldable ramp 61 so that the towable low-chassis trailer platform 1 and the foldable safety platform ramp units 6 together form a cross passage platform directly above the working pit. Figure 7 As shown;

[0052] Step 4: The construction personnel operate the power generation and energy storage unit 2 to provide reliable power output for the work, and at the same time connect the concrete vibration unit 3, lighting unit 4 and concrete pumping unit to the ready-to-work state.

[0053] Step 5: When pouring foundation concrete in the working pit, the construction workers use vehicles to transport the concrete to the concrete collection hopper 81 of the concrete pumping unit. The construction workers operate the standard concrete pump and the concrete pipeline rocker arm 82 to inject the concrete into the formwork of the line tower foundation leg in the working pit through the concrete pipeline unloading port. At the same time, the construction workers operate the concrete vibration unit 3 to vibrate synchronously to ensure the quality of concrete pouring. The lighting unit 4 provides lighting.

[0054] Step 6: After the concrete construction of the line tower foundation is completed and the key parameters are qualified, activate the telescopic outrigger 5 to retract, so that the traveling wheels 7 installed at the bottom of the towable low chassis trailer platform 1 touch the ground and the traveling wheels 7 lift off the ground. Use a construction vehicle to pull the towable low chassis trailer platform 1 directly above the working pit of the next line tower foundation construction site to complete one construction cycle.

[0055] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be permuted and combined. Those skilled in the art can exhaust all possibilities based on the mathematical knowledge of permutation and combination. Therefore, the present invention will not describe the technical solutions after permutation and combination one by one, but it should be understood that the technical solutions after permutation and combination have been disclosed by the present invention.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
