Description

Technical Field

[0001] The invention relates to a multi-functional safety construction platform and method for the foundation construction of low-voltage transmission lines, belonging to the field of safety facilities for the foundation construction of power lines. Background Art

[0002] The construction of transmission line projects is characterized by numerous points, wide areas, long lines, tight construction periods and short effective construction periods. For the foundation construction of transmission lines, due to the large number of foundations, linear distribution and wide cross-regional distribution, currently, the traditional foundation construction of transmission lines usually adopts two methods: large-scale foundation excavation and split-leg foundation excavation. Among them, the safety control of large-scale foundation excavation is difficult. Usually, multiple construction teams carry out construction simultaneously, and the levels of construction personnel vary, making safety management difficult. Moreover, the construction sites are scattered, and the safety control of the foundation construction sites is relatively difficult.

[0003] Currently, there is no special construction safety platform facility for the foundation construction of transmission lines. Basically, the original steel scaffolding is used to fix the foundation formwork on-site, and temporary springboards are lapped as the construction platform for construction personnel to carry out operations such as concrete placing and vibrating on-site. Construction personnel are at risk of falling into the foundation pit. At the same time, during the operation process of the staff, since the temporary springboard construction platform is connected to the formwork fixing system, the formwork will vibrate during the concrete placing, pouring and vibrating processes, increasing the difficulty of controlling the key index data of the foundation.

[0004] Therefore, it is urgent to propose a multi-functional safety construction platform and method for the foundation construction of low-voltage transmission lines to solve the above technical problems. Summary of the Invention

[0005] The research and development purpose of the invention is to solve the problems that there is no special construction safety platform facility for the traditional foundation construction of transmission lines, the original steel scaffolding is basically used to fix the foundation formwork on-site, the safety control is difficult, usually multiple construction teams carry out construction simultaneously, the levels of construction personnel vary, and the construction sites are scattered, and the safety control of the foundation construction sites is relatively difficult. A brief overview of the invention is given below to provide a basic understanding of certain aspects of the invention. It should be understood that this overview is not an exhaustive overview of the invention. It is not intended to identify the key or important parts of the invention, nor is it intended to limit the scope of the invention.

[0006] The technical solution of the invention:

[0007] Solution 1: A multi-functional safety construction platform for the foundation construction of low-voltage transmission lines, which includes a towable low-chassis trailer platform, a power generation and energy storage unit, a concrete vibration unit, a lighting unit, telescopic legs, and a foldable safety platform springboard unit. Telescopic legs are installed at the four corners of the bottom of the towable low-chassis trailer platform. A power generation and energy storage unit, a concrete vibration unit, and a lighting unit are installed on the towable low-chassis trailer platform. Foldable safety platform springboard units are installed on both sides of the towable low-chassis trailer platform.

[0008] Preferably: Travel wheels are installed at the four corners of the bottom of the towable low-chassis trailer platform.

[0009] Preferably: The foldable safety platform springboard unit includes a foldable springboard and a safety enclosure. When the foldable springboard is unfolded, the safety enclosure is fixedly installed on both sides of the foldable springboard.

[0010] Preferably: The towable low-chassis trailer platform is an H-shaped platform. Telescopic legs are installed at the four corners of the H-shaped platform. The telescopic legs include an oil cylinder and a support block. The oil cylinder is fixedly installed at the four corners of the H-shaped platform. The output end of the oil cylinder is vertically downward and is equipped with a support block.

[0011] Preferably: The power generation and energy storage unit includes a generator and an emergency DC power supply, and is 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. The motor-integrated concrete vibrator is electrically connected to the mobile power supply.

[0013] Preferably: A concrete pumping unit is also provided on the towable low-chassis trailer platform. The concrete pumping unit includes a concrete collection hopper, a standard concrete pump, a concrete pumping pipeline, a concrete pipeline swing arm, and a concrete pipeline discharge port. The standard concrete pump is connected inside the concrete collection hopper. The concrete pumping pipeline is installed on the concrete pipeline swing 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 discharge port.

[0014] Solution 2: A multi-functional safety construction method for the foundation construction of low-voltage transmission lines, which is realized based on Solution 1 and includes:

[0015] Step 1, start with the telescopic legs in the retracted state, make the travel wheels installed at the bottom of the towable low-chassis trailer platform touch the ground, and use a construction vehicle to tow the towable low-chassis trailer platform to directly above the working foundation pit at the construction site of the line tower foundation;

[0016] Step 2: Start the telescopic legs in the extended state until the bottom of the telescopic legs touches the ground and the running wheels are off the ground, until the towable low-bed trailer platform is adjusted to be stable, ensure that the platform plane is parallel to the ground, and the running wheel track exceeds the extension of the working foundation pit by more than 1 meter, and complete the positioning of the towable low-bed trailer platform;

[0017] Step 3: unfold the foldable safety platform springboard units on both sides of the towable low-bed trailer platform and firmly fix both ends of the foldable springboards so that the towable low-bed trailer platform and the foldable safety platform springboard units together form a cross-channel platform directly above the working pit position;

[0018] Step 4: Construction workers operate the power generation and energy storage units to provide reliable power output for the work, and at the same time turn on the concrete vibrating unit, lighting unit, and concrete pumping unit to prepare for work;

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

[0020] Step 6: After the concrete construction of the line tower foundation is completed and the key parameters are measured and qualified, the telescopic legs are activated and retracted, so that the running wheels installed at the bottom of the towable low-floor trailer platform touch the ground and the running wheels are off the ground. A construction vehicle is used to tow the towable low-floor trailer platform to the top of the working foundation pit of the next line tower foundation construction site, completing one construction.

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

[0022] 1. The combination of the travel wheels and retractable telescopic legs allows the platform to be quickly towed to different pit locations by construction vehicles during transportation, eliminating the need for complex disassembly or assembly. The retractable legs, combined with the lightweight and compact design of the trailer platform, enable immediate deployment at the construction site, significantly reducing equipment transfer time and accommodating the needs of continuous operations across multiple pits.

[0023] 2. The power generation and energy storage unit of the present invention can independently power transmission line construction sites in remote areas or areas with insufficient grid coverage, avoiding construction delays caused by power outages. It also provides a stable power source for units such as concrete vibration, pumping, and lighting, reducing reliance on external cables and the risk of leakage, thus complying with power construction safety regulations.

[0024] 3. The coordinated operation of the concrete collection hopper, the pumping pipeline rocker arm, and the vibrating unit of the present invention realizes the seamless connection of "transportation - pumping - vibration" of concrete, reduces manual handling and secondary operations, and lowers the labor intensity. At the same time, through the synchronous operation of the concrete pipeline unloading port and the vibration inside the formwork, concrete segregation is avoided, ensuring the compactness of the foundation pouring and improving the construction quality.

[0025] 4. After the two - side folding springboards of the present invention are unfolded, they form a cross - shaped platform that covers more than 1 meter outside the foundation pit, expanding the working surface and preventing the risk of personnel or materials falling. After the telescopic support legs are stretched, the trailer platform is separated from the ground contact, and the platform plane is parallel to the ground and evenly stressed, avoiding tipping accidents caused by uneven ground or foundation pit collapse.

[0026] 5. The trailer platform of the present invention can be reused for the construction of multiple iron tower foundations, reducing the number of special equipment purchases and the fixed - asset investment of construction enterprises. The steps from positioning, power supply to pouring are all carried out according to unified standards, reducing human operation differences, 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 the operation area, ensuring construction safety and efficiency in night or low - light environments, avoiding the risk of misoperation caused by insufficient lighting. At the same time, the platform structure is stable and self - powered, and can maintain the continuity of foundation construction under complex terrain or bad weather conditions, shortening the project cycle.

[0028] 7. The present invention reduces the manual operation links through mechanized and automated equipment, such as the pumping and vibrating units, reducing the probability of personnel being exposed to risks such as foundation pit collapse and mechanical injuries. The comprehensive advantages in terms of efficiency, safety, economy, and standardization are suitable for the modern management requirements of low - voltage transmission line foundation construction.
