Description

Technical Field

[0001] This application relates to the field of pipeline installation technology, and in particular to a hydraulic automated foundation pit pipeline installation trolley. Background Technology

[0002] Pipeline installation in foundation pits is a critical facility hidden within underground foundation pits, playing an indispensable role in urban construction and various engineering projects. The installation of pipelines in foundation pits requires careful planning. The direction, diameter, and material of the pipelines must be rationally determined based on the size of the foundation pit, geological conditions, and usage requirements. The installation process must strictly follow the specifications to ensure tight pipeline connections, reasonable slopes, smooth drainage, stable water supply, and safe power transmission. In foundation pit pipeline installation projects, traditional construction relies on manual handling and adjustment of pipelines, which is inefficient and unsafe.

[0003] In existing technologies, pipeline installation often relies on crane assistance, which can easily lead to uneven stress on pipeline joints, increasing the risk of breakage and affecting long-term reliability. Crane assistance cannot meet the flexible operation requirements in confined pit spaces. Furthermore, during pipeline installation, workers are required to assist in the operation within the pit, but the soil on both sides of the pit has low stability and is prone to collapse. The enormous impact and burying effect generated by the collapse can directly threaten the lives of on-site construction workers. At the same time, the collapse will squeeze and impact the supports and pipelines, requiring a large investment of manpower and resources to clear the collapsed soil and repair the damaged structure, increasing time costs. Summary of the Invention

[0004] To overcome the drawbacks of uneven stress on pipe joints leading to breakage and affecting long-term reliability, crane assistance cannot meet the flexible operation requirements in confined pit spaces. Furthermore, during pipe installation, workers are required to assist in the operation within the pit, but the soil on both sides of the pit has low stability and is prone to collapse. The huge impact and burying effect generated by the collapse can directly threaten the lives of on-site construction workers. The purpose of this invention is to provide a hydraulic automated pit pipe installation trolley to solve the above-mentioned shortcomings.

[0006] Furthermore, there are four sets of adjustment mechanisms. Two sets are fixedly installed on both sides of the first and second protective plates.

The first hydraulic cylinder is fixedly connected to the inner wall of the first connecting block, the first hydraulic rod is not in contact with the inner wall of the first connecting block, the adjustment rod is fixedly connected to the first hydraulic rod, and when the first hydraulic rod moves in the inner cavity of the first hydraulic cylinder, it drives the adjustment rod to slide in the inner cavity of the first connecting block and disengage from the inner cavity of the first connecting block.

[0007] Furthermore, the working door includes a door body and a door bolt, wherein the door bolt consists of a plug and a limiting block, the end of the door body away from the door bolt is rotatably connected to the inner cavity of the first protective plate, the plug is slidably connected to the door body, the limiting block is fixedly connected to the first protective plate, and the plug and the limiting block are engaged.

[0008] Furthermore, the moving mechanism includes a base beam, which is fixedly connected to the bottom ends of the first protective plate and the second protective plate respectively. One end of the base beam is movably connected to a caster wheel, and the end of the base beam away from the caster wheel is provided with a drive wheel. The outer surface of the drive wheel is provided with a first drive motor.

[0009] Furthermore, the lifting mechanism includes four fixed rods, which are distributed and fixed to the inner walls of the first and second protective plates on both sides. A second hydraulic cylinder is provided in the inner cavity of the fixed rod, and a second hydraulic rod is slidably connected to the inner cavity of the second hydraulic cylinder.

[0011] Furthermore, the hydraulic device is electrically connected to the first hydraulic cylinder and the second hydraulic cylinder, and the first drive motor and the control device are electrically connected.

[0012] Furthermore, the electric hoist comprises a second drive motor, a drum, a wire rope, and a hook. The wire rope is wound around the drum, and the end of the wire rope is fixedly connected to the hook. The motor is used to drive the drum to rotate, and the second drive motor is electrically connected to the control device.

[0013] The technical solution provided in this application has at least the following technical effects or advantages:

[0014] 1. By adopting adjustment and lifting mechanisms, this invention effectively solves the problem that in the existing technology, pipeline installation often relies on crane assistance, which can easily lead to uneven stress on the pipeline joints, causing breakage risks and affecting long-term reliability. Crane assistance cannot meet the flexible operation requirements in narrow foundation pit spaces. This invention, through adjustment and lifting mechanisms, can adjust the size of the equipment according to the width of the foundation pit and pipeline, as well as the space for construction operations, enabling the equipment to operate flexibly in narrow foundation pits.

[0015] 2. By employing a first and second protective plate, the problem of workers needing to assist in the installation of pipelines within the foundation pit is effectively solved. The low stability of the soil on both sides of the pit makes it prone to collapse, and the immense impact and burying effect of such a collapse directly threatens the lives of on-site workers. Furthermore, the collapse can compress and impact the supports and pipelines, requiring significant manpower and resources to clear the collapsed soil and repair damaged structures, increasing time costs. This invention allows workers to operate inside the equipment, preventing injury from soil collapse on both sides of the pit, reducing damage to construction equipment and installed pipelines, facilitating rapid repair of collapsed soil, and saving construction time.

[0020] For situations where flexible operation is not possible in confined spaces, this invention uses an adjustment mechanism and a lifting mechanism to adjust the size of the equipment according to the width of the pit and pipeline and the space available for construction work, enabling the equipment to operate flexibly in confined spaces. Furthermore, for situations where the soil on both sides of the pit is unstable and prone to collapse, this invention allows construction workers to work inside the equipment, preventing injury from soil collapse on both sides of the pit.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] Example 1:

[0023] Please see Figure 1 and Figure 2 As shown, a hydraulic automated foundation pit pipeline installation trolley includes a first protective plate 1, with adjusting mechanisms 2 at both ends of the first protective plate 1, and a second protective plate 3 at the end of the adjusting mechanisms 2 away from the first protective plate 1. A working door 4 is provided on the outer surface of the first protective plate 1. Moving mechanisms 5 are fixedly installed at the bottom ends of both the first protective plate 1 and the second protective plate 3. Lifting mechanisms 6 are fixedly installed on the inner walls of both the first protective plate 1 and the second protective plate 3. A first top plate 7 is provided at the top of the first protective plate 1, and a second top plate 8 is provided at the top of the second protective plate 3. A control device 9 is fixedly installed at one end of the second protective plate 3. A hydraulic device 10 is fixedly installed at one end of the second protective plate 3. An electric hoist 11 is installed on the inner wall of the second protective plate 3. In use, the trolley is placed on the foundation pit by the lifting equipment. The workers enter the cavity between the first protective plate 1 and the second protective plate 3 through the working door 4. The equipment assists in the laying of the pipeline. The first protective plate 1 and the second protective plate 3 are used to protect the workers and prevent the collapse of the foundation pit from injuring them. The moving mechanism 5 and the control device 9 are used to drive the equipment to move. The lifting mechanism 6 is used to adjust the height of the first top plate 7 and the second top plate 8. The electric hoist 11 is used to adjust the position of the pipeline.

[0024] Please see Figure 2As shown, the adjusting mechanism 2 includes a first connecting block 21, which is fixedly connected to the first protective plate 1. An adjusting rod 22 is slidably connected to the inner cavity of the first connecting block 21. A second connecting block 23 is fixedly connected to the end of the adjusting rod 22 away from the first connecting block 21. The second connecting block 23 is fixedly connected to the second protective plate 3. The adjusting mechanism 2 has four sets, with two sets fixedly installed on each side of the first protective plate 1 and the second protective plate 3. A first hydraulic cylinder and a first hydraulic rod are provided in the inner cavity of the first connecting block 21. The first hydraulic cylinder is fixedly connected to the inner wall of the first connecting block 21, and the first hydraulic rod is fixedly connected to the first connecting block 22. The inner wall of the connecting block 21 does not contact the connecting rod 22. The adjusting rod 22 is fixedly connected to the first hydraulic rod. When the first hydraulic rod moves in the inner cavity of the first hydraulic cylinder, it drives the adjusting rod 22 to slide in the inner cavity of the first connecting block 21 and disengage from the inner cavity of the first connecting block 21. The working door 4 includes a door body and a door bolt, wherein the door bolt consists of a plug and a limiting block. The end of the door body away from the door bolt is rotatably connected to the inner cavity of the first protective plate 1. The plug and the door body are slidably connected. The limiting block is fixedly connected to the first protective plate 1. The plug and the limiting block are engaged. The lifting mechanism 6 includes four fixing rods 61, which are distributed and fixed to the first protective plate 1 and the second protective plate. On both sides of the inner wall of the fixed rod 61, a second hydraulic cylinder is installed in the inner cavity of the fixed rod 61. A second hydraulic rod is slidably connected to the inner cavity of the second hydraulic cylinder. A lifting rod 62 is slidably connected to the inner cavity of the fixed rod 61. The second hydraulic rod and the lifting rod 62 are fixedly connected. The hydraulic device 10 is electrically connected to the first hydraulic cylinder and the second hydraulic cylinder. The distance between the first protective plate 1 and the second protective plate 3 can be adjusted according to the width of the construction pit. This facilitates adjustment based on the width of the pipeline and the pit. When adjusting the distance between the first protective plate 1 and the second protective plate 3, the first piston rod in the first hydraulic cylinder is moved by the hydraulic device 10, so that... The adjusting rod 22 slides inside the first connecting block 21 and disengages from the first connecting block 21. At this time, the distance between the first connecting block 21 and the second connecting block 23 increases. Simultaneously, the first top plate 7 slides on the second top plate 8, enabling the first top plate 7 and the second top plate 8 to protect the top of the worker. At the same time, the second cylinder inside the fixed rod 61 works to drive the second piston to move, causing the lifting rod 62 to slide inside the fixed rod 61. This allows the height of the first top plate 7 and the second top plate 8 to be adjusted, making it easy to adjust according to the height of the worker and ensuring that the internal height of the trolley meets the worker's working needs.

[0025] Please see Figure 2 and Figure 3As shown, the moving mechanism 5 includes a base beam 51, which is fixedly connected to the bottom ends of the first protective plate 1 and the second protective plate 3. One end of the base beam 51 is movably connected to a caster wheel 52, and the end of the base beam 51 away from the caster wheel 52 is provided with a drive wheel 53. A first drive motor 54 is provided on the outer surface of the drive wheel 53. The first top plate 7 and the second top plate 8 are slidably connected, and the lower surfaces of the first top plate 7 and the second top plate 8 are fixedly connected to the top end of the lifting rod 62. The first drive motor 54 is electrically connected to the control device 9. The electric hoist 11 includes a second drive motor, a drum, a wire rope, and a hook. The wire rope is wound on the drum, and the end of the wire rope is fixedly connected to the hook. The motor is used to drive the drum to rotate, and the second drive motor is electrically connected to the control device 9. The control device 9 controls the first drive motor. The motor 54 drives the drive wheel 53 to move on the foundation pit, thereby moving the trolley. At the same time, the casters 52 control the overall movement direction of the trolley. The electric hoist 11 is used to adjust the position of the pipe in the foundation pit. During the pipe position adjustment, the second drive motor, drum, wire rope and hook of the electric hoist 11 work together to achieve precise control. The motor serves as the power source to drive the drum to rotate. The wire rope wound on the surface of the drum is wound and unwound as the drum rotates. The hook at its end is firmly connected to the pipe lifting strap. With the assistance of the workers, the force of the hook is used to make the pipe tightly and precisely connected together. By adjusting the position of the hook, the force generated when the hook and the pipe come into contact is uniform, preventing the risk of pipe breakage and ensuring the protection of workers during the pipe installation process, thus reducing the danger during construction.

[0026] In summary, the trolley is placed on the foundation pit using lifting equipment. Workers enter the cavity between the first protective plate 1 and the second protective plate 3 through the working door 4. The equipment assists in the laying of pipelines. The first protective plate 1 and the second protective plate 3 are used to protect workers and prevent them from being injured by the collapsing foundation pit. The moving mechanism 5 and the control device 9 are used to drive the equipment to move. The lifting mechanism 6 is used to adjust the height of the first top plate 7 and the second top plate 8. The electric hoist 11 is used to adjust the position of the pipeline to ensure that the pipeline is tightly connected.
