[0001] This invention relates to an automated installation device, and more particularly to an automated installation device for rainwater and sewage concrete pipes, belonging to the field of design and manufacturing technology of pipeline installation engineering equipment. Background Technology

[0002] With social development, a large number of rural residents are migrating to cities. The construction of supporting facilities such as urban sewage treatment facilities is lagging behind the growth of the urban population. my country attaches great importance to the construction and management of urban sewage pipe networks, as sewage treatment is a major issue for improving urban development. Sewage treatment requires a complete sewage pipe network. Currently, most sewage pipe networks use reinforced concrete socket pipes during construction. These reinforced concrete socket pipes are prone to problems during construction, leading to sewage pipe leaks. The main reason for these leaks is the lack of suitable installation equipment. Therefore, construction workers often use loaders or excavators to install pipes. Because these are not specialized installation equipment, problems such as chipped edges and loose connections at pipe joints are easily caused, leading to leaks during operation. Summary of the Invention

[0025] In summary, the automated installation device of this application effectively solves the problems of continuous installation and precise splicing of rainwater and sewage pipes, while reducing damage to precast reinforced concrete pipe sections during the installation process.

[0026] The technical solution of this application will be further described below through specific embodiments:

[0027] Municipal stormwater and sewage pipeline projects involve large-diameter pipes, with total lengths ranging from tens of meters to several kilometers, requiring continuous mechanical installation to improve efficiency. Reinforced concrete stormwater and sewage pipes are widely used in engineering practice due to their lower cost. Each section is typically 2 meters long, and the weight varies from hundreds of kilograms to several tons depending on the pipe diameter. Once the trench for the stormwater and sewage pipelines is excavated and a compacted crushed stone bedding layer is laid, the construction and installation of the pipelines can begin. Transport vehicles deliver the reinforced concrete pipes to the site, and truck-mounted cranes or mobile cranes lift and place the pipe sections one by one along the trench with the crushed stone bedding layer. Then, installation equipment installs the pipe sections into place.

[0028] The reinforced concrete stormwater and sewage pipe installation device consists of three parts: a main support system, a front support system, and a rear support system. The main support system is located in the middle of the equipment, above and on both sides of the already installed reinforced concrete stormwater and sewage pipes. During the installation of the front-end pipe, it is fixed to the upper end of the already installed pipe, serving as support for the installation and tightening of the front-end pipe. A working platform can also be installed on top of the main support system for arranging gas stations and operator workstations. The front support system is located at the front of the equipment, in the forward direction of the reinforced concrete stormwater and sewage pipe installation, above and on both sides of the pipe to be installed. It is used for lifting and positioning the pipe to be installed. The rear support system is located at the rear of the equipment, providing support when the main support system moves forward and balancing the forces when the front support system moves forward.

[0029] The main support system includes a ring system surrounding the circular culvert, comprising front and rear fixed rings and front and rear movable rings on both sides. The front and rear fixed rings and the front and rear movable rings on both sides are connected by hinges on both sides. The front and rear fixed rings constitute the aforementioned fixed ring section, and the front and rear movable rings constitute the aforementioned movable ring section. Each of the three sets of pre-drilled holes is used to install the fastening steel ropes, which consist of three steel wire ropes. Each fastening steel rope has a lifting cylinder at its end, which can move the fastening device forward or backward. The front end of the rope has a hook that can hook onto the pipe wall of the section to be installed. The movable rings on both sides are connected to the main support through three sets of retractable horizontal cylinders. The horizontal cylinders can rotate perpendicular to the movable rings. The front and rear fixed rings are fixedly connected to the main support. The bottom of both sides of the main support is connected to the outrigger cylinders. Each main support, i.e., the aforementioned portal frame support, is composed of horizontal bars, vertical bars, and diagonal braces to maintain the stability of the support. At the same time, the main support is connected by multiple rods to form a stable main support system. In addition, steel plates are laid within the upper support area of ​​the main support to form a platform on the upper part of the main support. A hydraulic station and operator's cab are located on the upper part of this platform. The hydraulic station is used for the centralized supply and control of hydraulic oil required for the horizontal, vertical, and lifting cylinders of this device. The operator's cab is used to house the operator's table and chairs and the automated control console. Also on the same horizontal plane as the operating platform are guide beams and their sleeves within the main support area. A gear rack is located at the lower part of the guide beam, matching a gear set at the bottom inner side of the sleeve. The gear set includes unpowered and powered gears. The powered gears are powered by an electric motor on the platform and its matching reduction gearbox, and the power is transmitted to the powered gear set on the other side via a connecting shaft. A roller assembly is located on the upper inner side of the sleeve, which, together with the lower gear set, fixes the guide beam.

[0030] The front support system consists of a front support, a guide beam connected to the main support, a front crossbeam, a rear crossbeam, a vertical positioning cylinder, three sets of horizontal positioning cylinders, three sets of positioning sleeves, and two side outrigger cylinders. The front support structure is similar to the two main supports, consisting of horizontal bars, vertical bars, and diagonal bars to maintain its stability. The bottom of the left and right sides of the front support are connected to the outrigger cylinders, and the upper part is connected to the front end of the guide beam. A gear is installed at the lower part of the front section of the guide beam. The front support is connected to the vertical lifting cylinder and two sets of horizontal telescopic cylinders. The ends of the vertical lifting cylinder and the two sets of horizontal telescopic cylinders are connected to the three sets of positioning sleeves. Each positioning sleeve has a socket into which a positioning rod can be inserted. The positioning rod in the top socket can lift the front circular culvert, while the positioning rods in the two side sockets can adjust the circular culvert left and right. The two crossbeams can move back and forth at the front section of the guide beam via their lower sleeves. The lower part of the lower sleeve is equipped with a power gear, which is connected to the gear rack at the lower part of the front section of the guide beam, allowing the two crossbeams to move back and forth. The power gear is powered by an electric motor and its matching gearbox at the lower part of one of the crossbeams, and the power is transmitted to both sides through the connecting shaft.

[0031] The rear support system consists of a rear support, two rear outriggers on both sides, and the rear section of the guide beam. Like the front support, the rear support is composed of horizontal, vertical, and diagonal braces to maintain its stability. The two rear outriggers on both sides are connected to the bottom of the rear support.

[0032] The guide beam is detachable and can be connected into a single unit to facilitate equipment use. The contact surfaces of both the fixed and movable clamps with the circular culvert are made of materials with a high coefficient of friction that will not damage the reinforced concrete culvert.

[0033] Before use, the device will be transported to the reinforced concrete stormwater and sewage pipeline site. At the site, after the first section of stormwater and sewage pipe culvert is installed, the main support system of this device will be placed on top of the installed first section of stormwater and sewage pipe culvert. At this time, the front support system and the rear support system can be installed. The front and rear supports are connected to the main support system through guide beams.

[0034] During pipe section installation, firstly, the height of the fixed clamps is adjusted by controlling the extension and retraction of the outrigger cylinders of the main support system, ensuring that the front and rear fixed clamps are in close contact with the top of the culvert; then, the movable clamps on both sides are adjusted by controlling the extension and retraction of the horizontal cylinders of the main support system, ensuring they are in close contact with the culvert; next, the outrigger cylinders of the main support system are extended and retracted to create a certain contact pressure with the ground; then, the outrigger cylinders of the front and rear support systems are extended and retracted to remove them from contact with the ground; the length of the positioning cylinder of the front support system is adjusted (to be as short as possible) to allow it to move smoothly from the rear end of the pipe section to the front side; the crossbeam near the front support is moved to the front end by controlling the motor of the front support system; the guide beam is moved back and forth by the motor in the main support system controlling the power gear set, adjusting the position of the front and rear supports so that the positioning cylinder of the front support is located in front of the front end of the culvert; finally, the outrigger cylinders of the front and rear support systems are extended and retracted to maintain contact with the ground and a certain contact pressure; By controlling the extension and retraction of the positioning cylinder of the front support system, each set of positioning sleeves is inserted into the inner side of the pipe section wall. Positioning rods are then inserted into the insertion holes of the positioning sleeves. The positioning rod in the top insertion hole should be weighted to accommodate the counterweight required to lift the pipe section. Simultaneously, the crossbeam on the front guide beam at the rear end of the pipe section to be installed, along with its matching hook rope, can be used in conjunction with the positioning cylinder and related equipment to lift the pipe section. By controlling the extension and retraction of the positioning cylinder of the front support system, the pipe section is slightly lifted. At this point, the corresponding crossbeam on the rear guide beam of the pipe section, the cylinder, and its matching hook rope are used to lift the pipe section. By controlling... The positioning cylinder of the front support system adjusts the left and right position of the pipe section to be installed, and construction is carried out according to the predetermined axis. The front and rear crossbeams are moved to hoist the pipe section as close as possible to the front end of the installed pipe section. The cylinder is raised so that the hook rope at the rear end of the pipe section to be installed is removed from the outer wall of the pipe section. The hook at the front end of the steel rope is hooked onto the wall of the pipe section. By controlling the three lifting cylinders at the end of the steel rope, the three fastening steel ropes are moved backward, driving the pipe section to move towards the installed pipe section. Simultaneously, the positioning cylinder, positioning sleeve and positioning rod in the front support system adjust the axis of the pipe section to maintain the accuracy of the axis of the pipe section to be installed.

[0035] When moving the device after the pipe section is installed, the horizontal cylinders on both sides of the main support are extended and retracted to disengage the movable clamps on both sides from the pipe section; the four outrigger cylinders on both sides of the main support system are lifted off the ground by extending and retracting the outrigger cylinders on both sides; the fixed clamps of the main support system are disengaged from the pipe section by extending and retracting the outrigger cylinders of the front and rear support systems; and the main support system motor is controlled to move the lifted main support system forward along the guide beam until it reaches a suitable position on the upper part of the second circular culvert section that has been installed, and then stops.

[0036] Repeat the pipe section installation steps to install the next pipe section to be installed, until the entire rainwater and sewage pipe is installed.

[0037] The hydraulic station and generator of this device are electrically driven. The hydraulic station is connected to each oil cylinder through hydraulic pipelines. The control buttons of the hydraulic station are located on the control panel in the cab for easy operation by the operator.

[0038] Cameras can be installed at appropriate locations on the device to transmit real-time information to the control room or operating room, facilitating automated control during the pipe section installation process.

[0039] Example 1

[0040] Taking a reinforced concrete stormwater and sewage pipe section with a diameter of 1.5 meters and a wall thickness of 15 cm as an example, the device design is as follows:

[0041] The inner radius of the retaining ring is 0.9 meters, allowing for a 240-degree close fit with the outer wall of the circular culvert. The fixed retaining ring can fit with the outer wall at a 120-degree angle, while the two movable retaining rings on either side can fit with the outer wall at a 60-degree angle. The retaining rings are 100mm thick and 60mm wide, made of steel. The pre-drilled holes on both the fixed and movable retaining rings are 30mm in diameter. The horizontal hydraulic cylinder connecting the movable retaining rings is a 1-ton telescopic cylinder, approximately 400mm long. The main support's horizontal, vertical, and diagonal braces are made of 100×60mm steel. The vertical braces on the fixed retaining ring are located at the center of the fixed retaining ring's arc and on the left and right sides. At a 5-degree angle, the diagonal brace connects the outer vertical and horizontal bars of the support frame at a 45-degree angle. The support legs use 3t outrigger cylinders. The guide beam is made of 100×60mm steel, with a lower gear set diameter of 20mm and an upper roller diameter of 10mm. The guide beam sleeve wall thickness is 5mm. The platform plate thickness is 10mm. The upper crossbeam of the guide beam is made of 100×60mm steel. The upper positioning cylinder of the front support system uses a 5t cylinder, and the left and right side positioning cylinders use 1t cylinders. The fastening device uses 16mm steel rope with steel hooks at the ends. The outriggers of the front and rear support systems use 5t outrigger cylinders.
