Description

Technical Field

[0001] This application relates to the technical field of pipeline construction, and in particular to a pipe delivery device for municipal water supply and drainage. Background Technology

[0002] In the process of urbanization, municipal water supply and drainage pipes are an important part of urban infrastructure construction. During the laying of municipal pipelines, it is necessary to carry out pipe delivery treatment to ensure the construction of the pipeline.

[0003] Currently, existing pipe delivery devices generally use a hoisting method to place the pipe directly into a pre-dug ditch beside the road, then use mechanical equipment to grab the individual pipes again, and then transport the grabbed pipes to the installation location.

[0004] Regarding the aforementioned technologies, the process of installing pipelines requires repeated gripping of a single pipeline, resulting in a longer stroke for the robotic arm and thus reducing the efficiency of pipeline installation. Summary of the Invention

[0005] In order to continuously install pipelines and improve the efficiency of pipeline installation, this application provides a pipeline delivery device for municipal water supply and drainage.

[0006] The technical solution of the municipal water supply and drainage pipe delivery device provided in this application is as follows: A municipal water supply and drainage pipe delivery device, comprising: The box body has a storage cavity inside for storing pipes, and a receiving cavity at the bottom of the box body that communicates with the storage cavity, with a discharge port at the bottom of the receiving cavity. A sealing element is installed inside the housing. The sealing element is used to separate the storage cavity and the receiving cavity, and the sealing element is also used to block the discharge port. A clamping assembly is installed at the bottom of the housing, with the clamping part of the clamping assembly located below the discharge port. The clamping assembly is used to clamp the pipe inside the receiving cavity. The support legs are fixedly connected to the bottom of the housing, and the bottom of the support legs is fixedly connected to rollers.

[0007] By adopting the above technical solution, the box is moved directly above the pre-drilled trench using support legs and rollers, a large number of pipes are stored in the storage chamber, then the outlet is sealed with a sealing component, and then the storage chamber is connected to the receiving chamber. At this time, the pipes in the storage chamber will slide into a pipe into the receiving chamber.

[0008] Next, the sealing component is driven to release the blockage of the discharge port, and then the storage chamber and the receiving chamber are separated. At this time, the pipe in the receiving chamber will slide out from the discharge port. Then, the clamping component will clamp the pipe that has slid out from the receiving chamber and send it into the pre-drilled trench.

[0009] The moving housing and the repeated sealing components alternately seal the upper and lower ends of the receiving cavity, thereby enabling the clamping assembly to continuously clamp individual pipes and place them into the pre-drilled trench, achieving continuous pipe installation and improving pipe installation efficiency.

[0010] Optionally, a guide slope is provided on one side wall of the receiving cavity, so that there is a height difference between the two ends of the opening of the receiving cavity.

[0011] By adopting the above technical solution, the guide slope facilitates the sliding of the pipe into the receiving cavity. At the same time, the guide slope creates a height difference between the two ends of the receiving cavity opening, thereby preventing the two pipes from getting stuck at the opening at the upper end of the receiving cavity.

[0012] Optionally, the sealing component includes a partition plate, a sealing plate, and a drive gear. The partition plate and the sealing plate are both horizontally slidably connected to the housing. The partition plate is used to separate the storage cavity from the receiving cavity, and the sealing plate is used to seal the discharge port. Both the partition plate and the sealing plate are provided with drive racks. The drive gear is located between the partition plate and the sealing plate, and the drive racks on both the partition plate and the sealing plate mesh with the drive gear.

[0013] By adopting the above technical solution, the drive gear rotates. Since the partition plate and the sealing plate are located on both sides of the drive gear, when the partition plate moves towards the cavity, the sealing plate moves away from the cavity; when the partition plate moves away from the cavity, the sealing plate moves towards the cavity. That is, when the partition plate blocks the upper end of the cavity, the sealing plate releases the blockage on the lower end; and when the partition plate releases the blockage on the upper end, the sealing plate releases the blockage on the lower end.

[0014] When the partition plate blocks the upper end of the receiving cavity, a pipe located inside the receiving cavity will slide out from the discharge port. The partition plate blocks the upper end of the receiving cavity, thereby preventing the pipe located inside the storage cavity from sliding out.

[0015] When the partition plate is removed from the upper end of the receiving cavity, the storage cavity and the receiving cavity are connected, allowing a pipe located in the storage cavity to slide into the receiving cavity for storage.

[0016] By utilizing the combination of partition plates, sealing plates, and drive gears, multiple pipes in the storage chamber are continuously transferred to one in the receiving chamber for storage. Furthermore, a single pipe stored in the receiving chamber is transported to a pre-drilled trench using a clamping assembly, thereby achieving continuous operation.

[0017] Optionally, the partition plate has a guide ramp at the end away from the drive gear, and the guide ramp faces the storage cavity.

[0018] By adopting the above technical solution, the setting of the guide slope allows the pipe to move along the guide slope into the storage cavity when the partition plate abuts against the pipe, thereby reducing the damage to the pipe caused by the partition plate abutting against the pipe.

[0019] Optionally, the clamping assembly includes a fixed arm, a movable arm, a rotating arm, and a clamping hand. The fixed arm is fixedly connected to the bottom of the housing. The movable arm is slidably connected to the housing along the vertical direction. The rotating arm is hinged to the fixed arm and is also rotatably connected to the movable arm. The clamping hand is installed at the end of the rotating arm near the discharge port and is located below the discharge port.

[0020] By adopting the above technical solution, the movable arm is controlled to move vertically, thereby driving the rotating arm to rotate around the end point of the fixed arm, thus controlling the robot to move closer to or away from the discharge port.

[0021] The robotic arm is controlled by a movable arm to approach the discharge port, clamp the pipe, and then the robotic arm is controlled by the movable arm to move away from the discharge port toward the pre-drilled trench, thereby completing the installation of the pipe.

[0022] Optionally, the fixed arm is located between the movable arm and the gripper, and the distance between the movable arm and the fixed arm is greater than the distance between the fixed arm and the gripper.

[0023] By adopting the above technical solution, since the distance between the movable arm and the fixed arm is greater than the distance between the fixed arm and the gripper, it is more effortless to control the movable arm to move vertically.

[0024] Optionally, the clamping hand includes a movable sleeve, in which a movable spring is installed. One end of the movable spring is fixedly connected to the rotating arm, and the other end is fixedly connected to the movable sleeve. An abutment plate is installed at the end of the movable sleeve away from the fixed arm. The abutment plate is arc-shaped, and the protruding surface of the abutment plate is fixedly connected to the movable sleeve.

[0025] By adopting the above technical solution, the abutment plate is used to support the pipeline. The movable spring can buffer the pipeline that falls onto the abutment plate. At the same time, as the gap between the abutment plates changes during the rotation of the rotating arm, the movable spring ensures that the abutment plate can still firmly abut against the pipeline even when the gap between the abutment plates changes.

[0026] Optionally, a plurality of ball bearings are installed on the side of the abutment plate away from the movable sleeve.

[0027] By adopting the above technical solution, the contact plate will slide on the surface of the pipe during the rotation of the rotating arm, and the setting of the ball bearings can reduce the friction between the contact plate and the pipe.

[0028] Optionally, a transmission component is installed between the sealing plate and the movable arm, the transmission component being used to drive the movable arm to move when the sealing plate moves.

[0029] By adopting the above technical solution, the transmission component is designed so that the sealing plate can drive the movable arm to move during the movement, making the sealing component and the clamping assembly fit more tightly.

[0030] Optionally, the transmission component includes a driving gear and a driven gear, both of which are rotatably connected to the housing and are coaxially fixedly connected. A transmission rack is fixedly connected to the sealing plate and meshes with the driving gear. A movable rack is fixedly connected to the movable arm and meshes with the driven gear.

[0031] By adopting the above technical solution, when the drive gear drives the sealing plate to move, the transmission rack on the sealing plate will drive the drive gear to rotate. The rotation of the drive gear will drive the driven gear to rotate, and the rotation of the driven gear will drive the transmission rack and the movable arm to move. Thus, when the drive gear drives the sealing plate to move, the clamping assembly can be driven to clamp or reset the pipeline simultaneously.

[0032] In summary, this application includes at least one of the following beneficial technical effects: 1. By cooperating with the box, storage cavity, receiving cavity, sealing parts and clamping components, the sealing parts are used to seal the upper and lower ends of the receiving cavity in an alternating manner, so that the clamping components can continuously clamp a single pipe and put it into the pre-drilled trench, thereby realizing the continuous installation of the pipe and improving the efficiency of pipe installation. 2. Through the cooperation of partition plates, sealing plates and drive gears, multiple pipes in the storage chamber are continuously transferred to the receiving chamber for storage, and a single pipe stored in the receiving chamber is transported to the pre-drilled trench using a clamping assembly, thereby achieving the effect of continuous operation; 3. By utilizing the cooperation of the driving gear, driven gear, sealing plate, transmission rack, movable arm, and movable rack, when the driving gear drives the sealing plate to move, the rotation of the driven gear can drive the transmission rack and movable arm to move, thereby making the sealing component and clamping assembly fit more tightly.

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0040] This application discloses a municipal water supply and drainage pipe delivery device.

[0041] Reference Figure 1A municipal water supply and drainage pipe delivery device includes a housing, a sealing element, and a clamping assembly. The housing has a storage chamber for storing pipes, and a receiving chamber at the bottom of the housing, which communicates with the storage chamber. The receiving chamber has a discharge port at its bottom. The sealing element is installed inside the housing, separating the storage chamber and the receiving chamber, and also sealing the discharge port. The clamping assembly is installed at the bottom of the housing, with its clamping part located below the discharge port, and is used to clamp the pipes within the receiving chamber.

[0042] By using staggered sealing components to seal the upper and lower ends of the receiving cavity, the clamping assembly continuously clamps and inserts individual pipes into the pre-drilled trench, enabling continuous pipe installation and thus improving pipe installation efficiency.

[0043] The bottom of the box is fixedly connected to four legs, which are arranged in an array at the bottom of the box to support it. The bottom of each leg is fixedly connected to a roller, which facilitates the movement of the box along the pre-drilled trench.

[0044] The width of the receiving cavity is the same as the outer diameter of the pipe, ensuring that only one pipe can be accommodated within the cavity. A guide ramp is provided on one side wall of the receiving cavity, creating a height difference between the two ends of the cavity opening. When the pipe inside the storage tank slides into the receiving cavity, it rolls along the guide ramp into the cavity. If the two ends of the cavity opening are at the same height, the pipes at both ends of the opening can easily accumulate and cause blockage.

[0045] Therefore, the guide ramp not only facilitates the sliding of the pipe into the receiving cavity, but also prevents the two pipes from getting stuck at the opening at the top of the receiving cavity, making the pipe slide into the receiving cavity more smoothly.

[0046] In this embodiment, the sealing component includes a partition plate, a sealing plate, and a drive gear. The drive gear simultaneously drives the partition plate and the sealing plate to move, thereby sealing the upper and lower ends of the receiving cavity in an alternating manner. In other embodiments, a cylinder can also be used to drive the partition plate or the sealing plate individually, which can also achieve the alternating sealing of the upper and lower ends of the receiving cavity.

[0047] Both the partition plate and the sealing plate are horizontally slidably connected within the housing. The partition plate separates the storage chamber from the receiving chamber, i.e., it seals the upper end of the receiving chamber; the sealing plate seals the discharge port, i.e., it seals the lower end of the receiving chamber. Both the partition plate and the sealing plate are equipped with drive racks, with drive gears located between them, and the drive racks on both plates mesh with the drive gears.

[0048] A drive motor is also installed on the housing, and the drive motor is coaxially and fixedly connected to the drive gear, thereby driving the drive gear to rotate. Furthermore, this embodiment has two drive gears, which are coaxially and fixedly connected, and located at both ends along the length of the partition plate. Using two drive gears to drive the partition plate and the sealing plate to move synchronously makes the movement of the partition plate and the sealing plate more stable.

[0049] Since the partition plate and the sealing plate are located on both sides of the drive gear, when the partition plate moves towards the cavity, the sealing plate moves away from the cavity. Conversely, when the partition plate moves away from the cavity, the sealing plate moves towards the cavity. That is, when the partition plate seals the upper end of the cavity, the sealing plate releases the seal on the lower end; and when the partition plate releases the seal on the upper end, the sealing plate releases the seal on the lower end.

[0050] The drive motor drives the drive gear to rotate in the forward direction, and the partition plate blocks the upper end of the receiving cavity. At this time, a pipe located in the receiving cavity will slide out from the discharge port. The partition plate blocks the upper end of the receiving cavity to prevent the pipe located in the storage cavity from sliding out.

[0051] The drive motor drives the drive gear to rotate in the opposite direction, the partition plate releases the seal on the upper end of the receiving cavity, and the storage cavity and the receiving cavity are connected, so that a pipe located in the storage cavity slides into the receiving cavity for storage.

[0052] By utilizing the combination of partition plates, sealing plates, and drive gears, multiple pipes in the storage chamber are continuously transferred to one in the receiving chamber for storage. Furthermore, a single pipe stored in the receiving chamber is transported to a pre-drilled trench using a clamping assembly, thereby achieving continuous operation.

[0053] In an alternative embodiment, a guide ramp is provided at the end of the partition plate away from the drive gear, with the guide ramp facing the storage cavity.

[0054] When the partition plate seals the upper part of the receiving cavity, part of the pipe located at the bottom of the storage cavity will remain inside the receiving cavity. During the sealing process, the partition plate will compress the pipe, causing part of the pipe located in the receiving cavity to move completely into the storage cavity. The guide ramp design allows the pipe's peripheral wall to abut against the guide ramp when the partition plate abuts against it, thus enabling the pipe to move along the guide ramp into the storage cavity, thereby reducing the damage to the pipe caused by the partition plate abutting against it.

[0055] The clamping assembly includes a fixed arm, a movable arm, a rotating arm, and a clamping hand. There are two sets of fixed arms, movable arms, rotating arms, and clamping hands. The two sets of fixed arms, movable arms, and rotating arms control the corresponding clamping hands to move. The two sets of clamping hands are used to clamp the pipe by abutting against both sides of the pipe.

[0056] The fixed arm is fixedly connected to the bottom of the housing, the movable arm is slidably connected to the housing vertically, and the rotating arm is hinged to the fixed arm and also rotatably connected to the movable arm. A gripper is mounted on the end of the rotating arm near the discharge port, and is positioned below the discharge port. Controlling the vertical movement of the movable arm causes the rotating arm to rotate around the end point of the fixed arm, thereby controlling the robot arm to move closer to or away from the discharge port.

[0057] The robotic arm is controlled by a movable arm to approach the discharge port, clamp the pipe, and then the robotic arm is controlled by the movable arm to move away from the discharge port toward the pre-drilled trench, thereby completing the installation of the pipe.

[0058] In this embodiment, the fixed arm is located between the movable arm and the gripper. In other embodiments, the movable arm is located between the fixed arm and the gripper. Placing the movable arm between the fixed arm and the gripper can save space for the gripping assembly, making the gripping assembly occupy less space.

[0059] The distance between the movable arm and the fixed arm is greater than the distance between the fixed arm and the gripper. By setting the distance between the movable arm and the fixed arm to be greater than the distance between the fixed arm and the gripper, the lever arm between the movable arm and the fixed arm is greater than the lever arm between the fixed arm and the gripper, thus making it easier to control the movable arm to move vertically.

[0060] The clamping hand includes a movable sleeve, inside which a movable spring is installed. One end of the movable spring is fixedly connected to the rotating arm, and the other end is fixedly connected to the movable sleeve. An abutment plate is installed at the end of the movable sleeve away from the fixed arm. The abutment plate is arc-shaped, and the protruding surface of the abutment plate is fixedly connected to the movable sleeve.

[0061] When the abutment plate catches the fallen pipe, the movable spring can cushion the pipe as it falls onto the abutment plate. At the same time, as the gap between the abutment plates changes during the rotation of the rotating arm, the movable spring ensures that the abutment plate can still firmly abut against the pipe even when the gap between the abutment plates changes.

[0062] In one optional embodiment, a plurality of balls are installed on the side of the abutment plate away from the movable sleeve. Since the abutment plate is located at the bottom of the pipe when it first receives the pipe, as the rotating arm rotates, the abutment plate will slide on the surface of the pipe, so that the abutment plate slides from the bottom of the pipe to the top of the pipe. At this time, the pipe is disengaged from the abutment plate. The arrangement of the balls can reduce the friction of the abutment plate sliding from the bottom to the top of the pipe.

[0063] To ensure a tighter fit between the sealing element and the clamping assembly, a transmission component is installed between the sealing plate and the movable arm. This transmission component drives the movable arm to move when the sealing plate moves, so that when the sealing element performs staggered sealing of the upper and lower ends of the receiving cavity, the clamping assembly clamps and transports the pipeline accordingly, thus making the fit between the sealing element and the clamping assembly even tighter.

[0064] In this embodiment, the transmission components include a driving gear and a driven gear. In other embodiments, a winding wheel and a winding belt can also be used. The rotation of the winding wheel is driven by the movement of the sealing plate or the dividing plate, thereby winding the winding belt and controlling the up and down movement of the movable arm.

[0065] Both the driving gear and the driven gear are rotatably connected inside the housing, and the driving gear and the driven gear are coaxially fixedly connected. A transmission rack is fixedly connected to the sealing plate, and the transmission rack meshes with the driving gear. A movable rack is fixedly connected to the movable arm, and the movable rack meshes with the driven gear.

[0066] When the drive gear moves the sealing plate, the transmission rack on the sealing plate drives the drive gear to rotate. The rotation of the drive gear drives the driven gear to rotate, and the rotation of the driven gear drives the transmission rack and the movable arm to move. Thus, when the drive gear drives the sealing plate to move, the clamping assembly can be driven to clamp or reset the pipeline simultaneously.

[0067] A drive gear is coaxially fixedly connected between the driving gear and the driven gear. There are two drive gears. The drive gear away from the driving gear meshes with the movable arm on the side away from the driving gear. A drive belt is sleeved between the two drive gears. Both drive gears mesh with the drive belt. By using the meshing of the two drive gears and the drive belt, the two drive gears rotate synchronously, thereby causing the movable arms located on both sides of the discharge port to move synchronously vertically. In this way, the two grippers can move synchronously to complete the clamping and conveying of the pipeline.

[0068] The implementation principle of a municipal water supply and drainage pipe delivery device according to an embodiment of this application is as follows: a large number of pipes are stored in the storage chamber, and the box is moved to the top of the pre-drilled ditch using support legs and rollers. At this time, the sealing plate seals the lower end of the receiving chamber, and the upper end of the receiving chamber is connected to the storage chamber. Then, one of the pipes in the storage chamber slides into the receiving chamber.

[0069] Then the drive motor drives the drive gear to reverse. At this time, the partition plate gradually seals the upper end of the receiving cavity, while the sealing plate gradually releases the seal on the lower end of the receiving cavity. The movable arm moves downward, causing the abutment plate to move upward to near the discharge port. When the sealing plate completely releases the seal on the receiving cavity, the pipe falls from the discharge port onto the abutment plate.

[0070] Next, the drive motor drives the drive gear to rotate forward. At this time, the partition plate gradually releases the seal on the upper end of the receiving cavity, while the sealing plate gradually seals the lower end of the receiving cavity. The movable arm moves upward, causing the abutment plate to move downward until the pipeline is transported into the pre-drilled trench.

[0071] When the connecting plate delivers the pipeline into the pre-drilled trench, the partition plate completely releases the seal on the upper end of the receiving cavity, and the sealing plate completely seals the lower end of the receiving cavity. At this time, the upper end of the receiving cavity is connected to the storage cavity, and one of the pipelines in the storage cavity slides into the receiving cavity.

[0072] The moving housing repeatedly drives the motor to rotate, causing the clamping assembly to continuously clamp individual pipes and place them into the pre-drilled trench, thus enabling continuous pipe installation and improving pipe installation efficiency.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
