Description

Technical Field

[0028] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figure 1 , Figure 2 and Figure 3 This embodiment provides a pipe tray mechanism, including a tray trolley 1, a traveling assembly, a guide assembly, and a tray 7.

[0030] A through hole 101 is provided on one side of the pallet trolley 1 for the column to pass through, and a pallet 7 is installed on the other side of the pallet trolley 1. The pallet 7 is used to support the vertically oriented pipes transported by the robot arm.

[0031] A guide assembly is provided between the pallet trolley 1 and the column to guide the pallet trolley 1 vertically. A traveling assembly is mounted on the pallet trolley 1 to drive the pallet trolley 1 to move vertically. Thus, the pallet trolley 1 is vertically and flexibly mounted on the column via the guide assembly and the traveling assembly.

[0032] The pipe tray mechanism in this embodiment, due to the aforementioned structure, can support the pipes transported by the robotic arm, thereby reducing the vertical force on the robotic arm. This prevents the pipes from accidentally falling or colliding with other devices and causing damage. It should be noted that the direction of the uprights is parallel to the vertical direction.

[0033] In this embodiment, a nylon pad 8 is provided on the upper surface of the bottom wall of the tray 7. The purpose of providing the nylon pad 8 is to reduce the impact force of the pipes on the tray 7, thereby protecting the pipe tray mechanism and extending the service life of the pipe tray mechanism.

[0034] In this embodiment, the pipe pallet mechanism further includes a pallet drive assembly, which is mounted on the pallet trolley 1. The pallet drive assembly is used to drive the pallet 7 to extend or retract relative to the pallet trolley 1. The purpose of providing the pallet drive assembly is to extend the pallet 7 during operation and retract the pallet 7 during device transportation and standby, preventing the pallet 7 from accidentally colliding with other devices.

[0035] Specifically, the pallet drive assembly includes a reversing cylinder 9 and a pallet tilting arm 10. The pallet tilting arm 10 is hinged to the pallet trolley 1, with a pallet 7 mounted on one end. One end of the reversing cylinder 9 is hinged to the pallet trolley 1, and the other end of the reversing cylinder 9 is hinged to the other end of the pallet tilting arm 10, for driving the pallet tilting arm 10 and the pallet 7 to rotate around the hinge point between the pallet tilting arm 10 and the pallet trolley 1.

[0036] Specifically, the traveling assembly includes a motor 2, a reducer, a main shaft, a traveling gear 5, and a rack. The interior of the pallet trolley 1 has a groove communicating with the through hole 101. The motor 2 body is fixedly mounted on the side of the pallet trolley 1. The motor 2's shaft is connected to the main shaft via the reducer. After the main shaft passes through the side wall of the groove, the traveling gear 5 is fitted onto it. A rack extending vertically is provided on the outer side of the column corresponding to the mounting area of ​​the traveling gear 5. The traveling gear 5 meshes with the rack.

[0037] When moving, motor 2 drives the walking gear 5 to rotate through the main shaft. The walking gear 5 moves along the rack, thereby driving the entire pipe tray mechanism to move up and down.

[0038] Furthermore, two bearing seats 4 are installed on the inner sidewall of the groove, and the main shaft passes through the two bearing seats 4 and the two bearing seats 4 form a rotational support for the main shaft.

[0039] In this embodiment, the guide assembly includes multiple lifting rollers 6, which are spaced apart on the inner sidewall of the through hole 101 and abut against the outer side of the column. The lifting rollers 6 not only guide the tray 7 but also reduce the friction between the tray 7 and the column.

[0040] The working principle of the pipe tray mechanism in this embodiment is as follows:

[0041] The pipe pallet mechanism can use motor 2 and gearbox to generate driving force according to the different sizes of pipes, drive the walking gear 5 to walk along the rack on the column, and then drive the pallet trolley 1 and pallet 7 to slide on the column, quickly reach the bottom of the pipe, and use pallet 7 and pallet nylon pad 8 to support the bottom of the pipe for stable transportation.
