[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0031] like Figure 1-3 As shown, a pre-embedded sleeve installation system includes a gantry frame 3, a mounting plate 6, a limiting component 7, and a conveyor belt. There are two gantry frames 3, which are respectively erected on both sides of the ground rail. The sleeper mold 4 slides along the ground rail 5. Rollers corresponding to the ground rail 5 are provided on both sides of the sleeper mold 4. The rollers can be connected to a drive device, or a traction device corresponding to the sleeper mold 4 can be provided below the ground rail 5. Here, the power method of the sleeper mold 4 is not restricted in much detail.

[0032] A slide rail and rack extending parallel to the ground rail 5 are provided above the portal frame 3. The robotic arm 1 is correspondingly mounted on the crossbeam 2. The robotic arm 1 is a conventional six-axis robotic arm 1, and its electrical control and mechanical structure are not subject to too many restrictions. The slide rails are slidably mounted on the sliders at both ends of the crossbeam 2. At least one end of the crossbeam 2 is equipped with a drive motor. The drive motor fits the rack with a gear, thereby enabling the robotic arm 1 to move on the portal frame 3. The mounting plate 6 is set at the end of the robotic arm 1. The mounting plate 6 has a certain length and is used to connect the robotic claw and other auxiliary components. Specifically, robotic claws corresponding to the pre-embedded sleeves are provided at both ends of the mounting plate 6. In order to ensure the placement accuracy of the pre-embedded sleeves in the longitudinal direction of the robotic claws, the limiting member 7 is set in the middle of the mounting plate 6. By abutting against the edge of the sleeper mold 4, the mounting plate 6 is limited, thereby ensuring that the elevation of the robotic claws is constant and improving the placement accuracy of the pre-embedded sleeves.

[0033] In this embodiment, a conveyor belt is used for feeding the pre-embedded sleeves. The conveyor belt is a conventional structure and is not shown in the figure. Specifically, the conveyor belt extends to the side of the gantry frame 3. Multiple placement stations are provided on the conveyor belt, which are evenly distributed along its surface. Each placement station has two pre-embedded sleeves corresponding to two mechanical claws. The placement station is a plug-in post, and the pre-embedded sleeve is sleeved on the plug-in post. The drive device of the conveyor belt and the robotic arm 1 are linked through a controller to realize automated feeding, so that two pre-embedded sleeves can be picked up and placed at the same time, thereby improving production efficiency by synchronizing the use of two pre-embedded sleeves.

[0034] In an optional embodiment, the mechanical claw is slidably assembled along the length of the mounting plate 6 via the base 11. A slide rail corresponding to the base 11 is provided on the side of the mounting plate 6, and a first driving component corresponding to the base 11 is provided on the mounting plate 6. The first driving component can be any type of cylinder, such as a pneumatic cylinder or an electric cylinder, so that the spacing of the mechanical claw can be adjusted according to the actual sleeper model produced.

[0035] In this embodiment, the mechanical gripper includes a pump body 15 and gripper bodies 8. The pump body 15 is mounted on a base 11, and a sealing sleeve 9 is connected to the bottom of the base 11. The pump body 15 is connected to the inner cavity of the sealing sleeve 9 through a connecting pipe, so that the medium can be supplied to or discharged from the inside of the sealing sleeve 9. The three gripper bodies 8 are slidably assembled along the radial direction of the sealing sleeve 9, thereby controlling the internal pressure of the sealing sleeve 9 to realize the extension and retraction of the gripper bodies 8. There are three mounting holes for the gripper bodies 8 evenly distributed around the circumference of the sealing sleeve 9. The mounting holes and the gripper bodies 8 are slidably and sealed together. One end of the gripper body 8 that extends out of the sealing sleeve 9 is folded downward. A rubber pad is provided on the inner side of the folded end. The inner wall of the rubber pad is arc-shaped and used to clamp the pre-embedded sleeve.

[0036] In this embodiment, the mechanical gripper also includes a rotary driver 17, which is a stepper motor. The pump body is connected to the base through the rotary driver. Specifically, the spindle of the rotary driver is fixed on the upper end face of the pump body shell. The rotary driver can drive the pre-embedded sleeve to rotate through the pump body and the gripper body, so as to be threaded onto the positioning bolt of the sleeper mold.

[0037] The outlet and inlet of the pump body 15 are connected to an electric control valve via connecting pipes. The electric control valve is connected to the inner cavity of the sealing sleeve 9 and the medium tank, respectively. By controlling the electric control valve, the outlet of the pump body 15 is connected to the inner cavity of the sealing sleeve 9, so that the medium can be supplied into the sealing sleeve 9, causing the claw 8 to move outward in the mounting hole to release the pre-embedded sleeve. Alternatively, the pipeline can be switched by the electric control valve, so that the inlet of the pump body 15 is connected to the inner cavity of the sealing sleeve 9, thereby discharging the medium from the inside of the sealing sleeve 9, reducing the internal pressure, and causing the mechanical claw to move inward and clamp the pre-embedded sleeve.

[0038] In this embodiment, the medium is preferably hydraulic oil.

[0039] In an optional embodiment, the lower end of the sealing sleeve 9 is open, and the cover plate 10 is fixedly mounted by bolts. The cover plate 10 has a mounting groove corresponding to the claw body 8 on its upper part. The middle part of the cover plate has an inner cavity corresponding to the sealing sleeve 9. The mounting groove is square and extends into the inner cavity of the cover plate. The claw body 8 that fits into the mounting groove is square, thereby reducing the difficulty of production.

[0040] In an optional embodiment, a sealing ring is provided between the sealing sleeve 9 and the cover plate 10, or the sealing sleeve 9 and the cover plate 10 are tightened with bolts to achieve a seal. The sealing sleeve 9 has a certain wall thickness, and the mounting groove extends to the inner wall of the sealing sleeve 9. A stop flange is provided at the end of the claw body 8 that extends into the mounting groove. The cross-section of the mounting groove is adapted to the cross-section of the stop flange. The outer wall of the stop flange is provided with a sealing ring corresponding to the mounting groove and the sealing sleeve 9, thereby achieving a sliding seal. A stop platform corresponding to the stop flange is provided at the outer end of the mounting groove corresponding to the outer side of the sealing sleeve 9. The cross-section of the stop platform is adapted to the cross-section of the main body of the claw body 8. The stroke of the claw body 8 is the distance between the inner wall of the sealing sleeve 9 and the stop platform. The stop platform stops the stop flange to limit the outward stroke of the claw body 8. The bend of the claw body 8 stops the outer wall of the cover plate 10 to limit the inward stroke of the claw body 8.

[0041] In an optional embodiment, a mounting sleeve 13 corresponding to the sealing sleeve 9 is provided below the pump body 15. The pump body 15 is externally equipped with a housing. The pump body 15 is driven by a motor. The mounting sleeve 13 is located at the lower end of the housing of the pump body 15. A sliding column 16 extending into the mounting sleeve 13 is provided at the upper end of the sealing sleeve 9. The sliding column 16 is slidably assembled in the mounting sleeve 13. A compression spring is provided inside the mounting sleeve 13 to abut against the sliding column 16, giving the sliding column 16 a downward movement tendency. This facilitates the positioning of the pre-embedded sleeve into the sleeper mold. It also prevents the pre-embedded sleeve from making hard contact with the template when it is placed downward. The compression spring buffers the movement and ensures that the pre-embedded sleeve can be finally positioned. The mounting sleeve 13 has a strip-shaped hole extending along its length on its side. The limiting bolt 14 passes through the strip-shaped hole and is assembled on the sliding column 16. The limiting bolt 14 and the strip-shaped hole limit the stroke of the compression spring. When the limiting bolt 14 abuts against the lower end of the strip-shaped hole, the pre-embedded sleeve is installed in place.

[0042] In an optional embodiment, the limiting member 7 is an L-shaped plate, one end of which is slidably mounted on the mounting plate 6, and the other end is folded outward horizontally to stop the upper edge of the sleeper mold 4. The limiting member 7 and the mechanical claw are located on both sides of the mounting plate 6.

[0043] Two longitudinal strip holes are provided at one end of the limiting member 7. Locking bolts corresponding to the strip holes are provided on the mounting plate 6 to fix the limiting member 7 so that the limiting member 7 can be adjusted in the longitudinal position. A central hole is provided at one end of the limiting member 7 that extends horizontally. A position sensor 12 is installed in the central hole. The position sensor 12 is connected to the control circuit of the robotic arm 1 to ensure the installation accuracy of the pre-embedded sleeve.

[0044] Furthermore, the sleeper mold 4 has rollers on both sides corresponding to the ground rail 5. The rollers are connected to the drive motor or the sleeper mold 4 is connected to other traction equipment. The outside of the sleeper mold 4 is equipped with a sensing terminal, such as an infrared sensing terminal or a Hall sensing terminal. The side of the gantry frame 3 is equipped with a position sensing element corresponding to the sensing terminal, which is an infrared sensor or a Hall sensor corresponding to the sensing terminal.

[0045] Alternatively, the position sensing element may be a position sensor extending toward the sleeper mold 4, so as to provide position feedback by contacting the sleeper mold 4.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
