Description

Technical Field

[0001] This invention relates to the field of elevator component processing technology, specifically to an automatic cleaning machine for elevator buffer cylinders. Background Technology

[0002] Elevator buffers are critical safety devices installed at the bottom of the elevator shaft, forming the last physical protective barrier of the elevator system. Their main function is to absorb the impact kinetic energy of the car or counterweight in extreme situations such as wire rope breakage or insufficient traction, and to prevent the car from directly impacting the bottom or top of the shaft through deceleration and buffering.

[0003] The elevator buffer mainly consists of a cylinder, a reset block, a lower pressure column, a reset spring, a ring, a first connecting block, a second connecting block, upper contacts, and lower contacts. Its core structure is the cylinder, which serves as the main body of the buffer. A spring is installed on the outer top, and an oil seal is located on the top inside. During processing, the inner wall of the cylinder needs to be cleaned. Currently, cleaning is mainly done semi-manually and semi-automatically. Loading and unloading are done manually, while the cleaning process can be completed by cleaning equipment. This operation is inefficient. Furthermore, it is difficult to ensure the precise positioning of the cylinder in the cleaning equipment during manual loading. Deviations in the cylinder's placement can cause the cleaning equipment (such as nozzles and brushes) to fail to accurately align with the target area on the inner wall of the cylinder. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an automatic cleaning machine for elevator buffer cylinders that completes the four processes of loading, cleaning, unloading and waiting for loading in sequence through a turntable mechanism, thereby achieving fully automatic cleaning, eliminating manual labor, increasing operating efficiency, and ensuring clamping accuracy and cleaning efficiency; in addition, the loading, cleaning and unloading are carried out simultaneously.

[0005] The technical solution of this invention is to provide an automatic cleaning machine for elevator buffer cylinders with the following structure: a worktable, a feeding device, a discharging device, a turntable mechanism, and a cleaning head; the feeding device is located at the feeding end of the worktable and is arranged along the X-axis; the discharging device is located at the discharging end of the worktable and is arranged along the X-axis; the cleaning head is located above the worktable and is arranged along the Z-axis; the turntable mechanism includes a power component and a turntable support, the turntable support is connected to the power component and rotates through the power component; the turntable support has a first channel, a second channel, a third channel, and a fourth channel; the worktable has a feeding station, a cleaning station, a discharging station, and a preparation station; the turntable mechanism includes a power component, a cleaning station, a discharging station, and a preparation station; the rotating head is located above the worktable and is arranged along the Z-axis. The first, second, third, and fourth channels of the turntable support rotate and switch sequentially between the loading station, cleaning station, unloading station, and preparation station on the worktable. Each of the first, second, third, and fourth channels is equipped with a positioning structure for positioning the buffer cylinder during loading, cleaning, and unloading. During operation, the cleaning head cleans the buffer cylinder located in the cleaning station channel on the turntable support. At the same time, the loading device sends the buffer cylinder into the loading station channel on the turntable support, and the unloading device sends the buffer cylinder out of the unloading station channel on the turntable support. Meanwhile, the preparation station channel on the turntable support remains empty.

[0006] The turntable support is a rectangular three-dimensional structure. The first channel, the second channel, the third channel and the fourth channel are located on the four sides of the turntable support respectively. Each channel includes a first positioning hole and a second positioning hole arranged in parallel.

[0007] The second positioning hole is provided with a positioning tube for positioning the buffer cylinder. The positioning tube is provided with an axial positioning structure inside for axial positioning of the buffer cylinder after it is installed. The middle part of the positioning tube is provided with a third positioning hole.

[0008] The axes of the first positioning hole on the first side of any three adjacent sides of the turntable bracket, the axis of the third positioning hole on the second side, and the axis of the center hole on the third side are on the same straight line. In the unloading state, the push rod of the feeding device passes through the first positioning hole at the feeding station and the third positioning hole on the positioning tube at the preparation station, and extends out of the buffer cylinder body located in the positioning tube at the unloading station.

[0009] At the loading station, the third positioning hole on the side of the turntable bracket is located below the positioning tube. At the cleaning station, the positioning tube on the side of the turntable bracket is located to the right of the third positioning hole in the working rotation direction. Correspondingly, at the unloading station, the positioning tube on the side of the turntable bracket is located below the third positioning hole in the working rotation direction.

[0010] The turntable bracket rotates 90° for each processing step. There is a gap between the bottom of the turntable bracket and the worktable, allowing the positioning tube on the side of the turntable bracket to extend out.

[0011] The feeding device is provided with a first push rod, and the unloading device is provided with a second push rod. The first push rod and the second push rod are arranged in parallel, and the second push rod is located below the first push rod.

[0012] The workbench has a notch located directly below the turntable support, providing space for the positioning tube on the turntable support to rotate.

[0013] With the above structure, the present invention has the following advantages: 1. An integrated turntable mechanism links the four key processes of "loading, cleaning, unloading, and pre-loading (waiting)" into a continuous cycle, achieving fully automated cleaning, eliminating manual labor, and increasing operational efficiency. 2. Automated loading and unloading via the loading and unloading devices ensure better positioning of the buffer cylinders being cleaned, guaranteeing clamping accuracy and increasing cleaning efficiency. 3. The turntable mechanism can rotate the loaded buffer cylinders from the loading station to the cleaning station, simultaneously sending the cleaning buffer cylinders to the unloading station and pushing them out via the unloading device. The unloading station is then rotated to the pre-loading station. This structure achieves seamless connection between loading, cleaning, and unloading, allowing for the next round of loading and the previous round of unloading while cleaning one buffer cylinder, significantly improving processing efficiency.

[0014] As an improvement, the turntable support is a rectangular three-dimensional structure, with the first channel, the second channel, the third channel and the fourth channel located on the four sides of the turntable support respectively, and each channel includes a first positioning hole and a second positioning hole arranged in parallel.

[0015] As an improvement, a positioning tube is provided inside the second positioning hole for positioning the buffer cylinder. The positioning tube has an axial positioning structure inside for axial positioning of the buffer cylinder after it is installed. A third positioning hole is provided in the middle of the positioning tube for precise positioning during cleaning, so that the cleaning head can clean the entire inner wall of the buffer cylinder and prevent impurities from remaining.

[0016] As an improvement, the axes of the first positioning hole on the first side of any three adjacent sides of the turntable bracket, the axis of the third positioning hole on the second side, and the axis of the center hole on the third side are all on the same straight line. In the unloading state, the push rod of the feeding device passes through the first positioning hole at the feeding station and the third positioning hole on the positioning tube at the preparation station, and extends out of the buffer cylinder inside the positioning tube at the unloading station. This connects the four key processes of feeding, cleaning, unloading, and pre-feeding into a continuous cycle, increasing the connection between each step and improving efficiency.

[0017] As an improvement, the third positioning hole on the side of the turntable bracket at the loading station is located below the positioning tube. At the cleaning station, the positioning tube on the side of the turntable bracket is located to the right of the third positioning hole in the working rotation direction. Correspondingly, at the unloading station, the positioning tube on the side of the turntable bracket is located below the third positioning hole in the working rotation direction. This can stagger the loading and unloading positions, avoid the inability to push loading and push unloading at the same height, and improve the compactness of the structure.

[0018] As an improvement, the turntable support rotates 90° for each processing step, and a gap is provided between the bottom of the turntable support and the worktable to allow the positioning tube on the side of the turntable support to extend, further improving the compactness.

[0019] As an improvement, the feeding device is provided with a first push rod, and the unloading device is provided with a second push rod. The first push rod and the second push rod are arranged in parallel, and the second push rod is located below the first push rod. This structure can ensure that they do not interfere with each other and that the feeding and unloading work normally.

[0020] As an improvement, the worktable is provided with a notch located directly below the turntable support, providing space for the positioning tube on the turntable support to rotate. Attached Figure Description

Detailed Implementation

[0028] The invention will now be further described with reference to the accompanying drawings.

[0029] like Figure 1-6 As shown, the automatic cleaning machine for elevator buffer cylinders of the present invention includes a workbench 1, a feeding device 2, a discharging device 3, a turntable mechanism 4, and a cleaning head 5.

[0030] like Figure 1 and Figure 2 As shown, the feeding device 2 is located at the feeding end of the worktable 1 and is arranged along the X-axis, and the unloading device 3 is located at the unloading end of the worktable 1 and is arranged along the X-axis. The feeding device 2 is equipped with a cylinder and a first push rod 15, and the unloading device 3 is equipped with a cylinder and a second push rod 16. The first push rod 15 and the second push rod 16 are arranged parallel to each other, and the second push rod 16 is located below the first push rod 15. The first push rod 15 pushes the buffer cylinder body in to the right. The first push rod 15 also pushes to the right to push the buffer cylinder body out.

[0031] like Figure 3 As shown, the cleaning head 5 is located above the workbench 1 and is set along the Z-axis. During operation, it moves downwards, starts cleaning after reaching the position, and then returns to its original position after completion.

[0032] The turntable mechanism 4 includes a power component and a turntable support 6. The turntable support 6 is connected to the power component and rotates through the power component. The turntable support 6 is provided with a first channel 7, a second channel 8, a third channel 9, and a fourth channel 10. The workbench 1 is provided with a loading station, a cleaning station, a unloading station, and a preparation station. The first, second, third, and fourth channels of the turntable support 6 rotate and switch sequentially at the loading station, cleaning station, unloading station, and preparation station of the workbench 1.

[0033] The first, second, third, and fourth channels are all equipped with positioning structures for positioning the buffer cylinder during loading, cleaning, and unloading. During operation, the cleaning head 5 cleans the buffer cylinder located in the cleaning station channel on the turntable support 6. At this time, the loading device 2 sends the buffer cylinder into the loading station channel on the turntable support 6, while the unloading device 3 sends the buffer cylinder out of the unloading station channel on the turntable support 6. Meanwhile, the preparation station channel on the turntable support 6 remains empty.

[0034] The turntable support 6 has a rectangular three-dimensional structure. The first channel 7, the second channel 8, the third channel 9 and the fourth channel 10 are located on the four sides of the turntable support 6 respectively. Each channel includes a first positioning hole 11 and a second positioning hole 12 arranged in parallel.

[0035] The turntable support 6 rotates clockwise during operation, turning 90 degrees each time. From the start of feeding to the end of feeding, it rotates together with the buffer cylinder. When it reaches the preparatory station, it is empty and does not have the buffer cylinder.

[0036] The second positioning hole 12 is provided with a positioning tube 13 for positioning the buffer cylinder. The positioning tube 13 is provided with an axial positioning structure inside for axial positioning of the buffer cylinder after it is installed. The middle part of the positioning tube 13 is provided with a third positioning hole 14, which is arranged radially along the positioning tube 13 and penetrates the entire positioning tube 13.

[0037] A portion of the buffer cylinder is embedded in the positioning tube 13 for positioning and fixation.

[0038] The axes of the first positioning hole 11 on the first side of any three adjacent sides of the turntable bracket 6, the axis of the third positioning hole 14 on the second side of the positioning tube 13, and the axis of the center hole of the positioning tube 13 on the third side are on the same straight line. In the unloading state, the push rod of the feeding device 2 passes through the first positioning hole 11 located at the feeding station, the third positioning hole 14 on the positioning tube 13 at the preparatory station, and extends out of the buffer cylinder located in the positioning tube 13 at the unloading station.

[0039] At the loading station, the third positioning hole 14 on the side of the turntable bracket 6 is located below the positioning tube 13. At the cleaning station, the positioning tube 13 on the side of the turntable bracket 6 is located to the right of the third positioning hole 14 according to the working rotation direction. Correspondingly, at the unloading station, the positioning tube 13 on the side of the turntable bracket 6 is located below the third positioning hole 14 according to the working rotation direction.

[0040] The turntable support 6 rotates 90° for each processing step. There is a gap between the bottom of the turntable support 6 and the worktable 1, allowing the positioning tube 13 on the side of the turntable support 6 to extend out.

[0041] The workbench 1 has a notch, which is a rectangular hole in this embodiment with a hollowed-out bottom. The notch is located directly below the turntable support 6, providing space for the positioning tube 13 on the turntable support 6 to rotate.

[0042] Work process: 1. Initial State Setting: The positioning tubes 13 of the turntable brackets 6 corresponding to the loading, cleaning, and unloading stations are already equipped with buffer cylinders; in the preparatory state, the positioning tubes 13 at the bottom of the turntable brackets 6 are empty. 2. Loading Feeding and Insertion: The first push rod 15 of the feeding device pushes a new buffer cylinder into the positioning tube 13 on the left side of the turntable support (feeding station). The right end of the buffer cylinder is inserted into the positioning tube until its internal axial positioning surface abuts, completing precise positioning.

[0043] 3. Cleaning: The cleaning head 5 descends to perform a cleaning operation on the buffer cylinder located at the top position (cleaning position) of the turntable bracket 6.

[0044] 4. Unloading: The second push rod 16 of the material feeding device pushes the cleaned buffer cylinder, located at the right-side station (unloading station) of the turntable support, out of the equipment. This action makes the right-side positioning tube empty. 5. Station change (turntable rotation): After all operations in the current cycle are completed, including loading, cleaning, and unloading, the turntable support 6 rotates 90 degrees clockwise.

[0045] The cylinder (just loaded) at the original left-side workstation (loading position) rotates to the top workstation (cleaning position) to prepare for cleaning.

[0046] The cylinder (already cleaned) at the original top station (cleaning station) is rotated to the right station (unloading station) in preparation for unloading.

[0047] The positioning tube (already loaded, now empty) of the original right-side workstation (unloading position) is rotated to the bottom workstation (preparatory position).

[0048] The positioning tube (initially empty) at the bottom station (preparatory station) is rotated to the left station (loading station) to prepare to receive the next new cylinder.
