Description

Technical Field

[0001] The utility model relates to the technical field of vacuum sucker pile lifting tools in the pipe pile industry, and particularly relates to a vacuum sucker pile lifting tool with a cleanable filter chamber. Background Art

[0002] The sucker pile lifting tool is a very important transfer device in the pipe pile production process, and various types of pipe piles can be transferred through the sucker pile lifting tool. Due to the large amount of dust and harsh environment at the production site of the pipe pile industry, the service life of the vacuum pump on the traditional pipe pile sucker pile lifting tool is greatly reduced by the environmental impact. Therefore, in order to prevent dust from being sucked into the vacuum pump and affecting the equipment life, the traditional vacuum sucker pile lifting tool often sets multiple-stage filtration, which will improve the service life of the equipment to a certain extent, but the subsequent problem is that the filter is frequently blocked, and the filter element needs to be continuously replaced, reducing the production efficiency. Content of the Utility Model

[0005] The steel frame is a closed box body, and the inner cavity is divided into an upper vacuum filter chamber and a lower vacuum filter chamber by a partition board. Among them, the multiple groups of rubber sucker components are respectively communicated with the lower vacuum filter chamber through a first vacuum pipeline, and the vacuum system components are communicated with the upper vacuum filter chamber through a second vacuum pipeline;

[0014] The inventive point of the present utility model is to make the entire steel frame into a closed space, separate it with a partition in the middle of the inner cavity, and open communication holes at both ends of the partition to ensure the communication between the upper and lower parts. When the vacuum pump is turned on, the steel frame can be used as a pre-vacuum filtration chamber to improve efficiency, and the dust on the surface of the pipe pile can be sucked into the inner cavity of the lower vacuum filtration chamber through the vacuum pipeline, so that the lower vacuum filtration chamber serves as a primary filter to isolate most of the dust, and a small part of the dust will be brought into the upper vacuum filtration chamber and finally absorbed by the primary filter provided between the vacuum pump and the steel frame.

[0024] Embodiment 1

[0025] The present utility model provides a vacuum suction cup lifting device with a cleanable filter chamber. Please refer to Figures 1-5, including a steel frame 1, multiple groups of rubber suction cup assemblies 2, and a vacuum system component 3; the multiple groups of the rubber suction cup assemblies 2 are distributed at intervals along the length direction of the steel frame 1, and each group of the rubber suction cup assemblies 2 is respectively floatingly connected to the steel frame 1 through a spring mechanism 4; the steel frame 1 is a closed box body, and its inner cavity is divided into an upper vacuum filtration chamber 6 and a lower vacuum filtration chamber 7 by a partition 5, wherein the multiple groups of the rubber suction cup assemblies 2 are respectively communicated with the lower vacuum filtration chamber 7 through a first vacuum pipeline 102, and the vacuum system component 3 is communicated with the upper vacuum filtration chamber 6 through a second vacuum pipeline 101; at least one communication hole is opened on the partition 5 so that the upper vacuum filtration chamber 6 and the lower vacuum filtration chamber 7 communicate with each other, and the vacuum system component 3 is used to drive the multiple groups of the rubber suction cup assemblies 2 to adsorb and lift piles respectively.

[0026] In some embodiments, two communication holes are opened on the partition 5, symmetrically distributed at both ends of the partition 5, which can not only ensure the communication between the upper vacuum filtration chamber 6 and the lower vacuum filtration chamber 7, but also block most of the dry dust in the lower vacuum filtration chamber 7, so that the lower vacuum filtration chamber serves as a primary filter to isolate most of the dust.

[0027] Specifically, an observation window 8 is provided at the end of the steel frame 1 to check the inner cavity of the steel frame 1 through the observation window 8, and there are two groups of the observation windows 8, symmetrically distributed at both ends of the lower vacuum filtration chamber 7.

[0028] Furthermore, the observation window 8 is closed by a cover plate so that the lower vacuum filtration chamber 7 is in a closed state.

[0029] Furthermore, a primary filter is provided at the inlet of the vacuum pump of the vacuum system component 3 to filter the remaining dry dust in the upper vacuum filtration chamber 6.

[0030] Specifically, a manual ball valve 9 is installed on the lower vacuum filtration chamber 7 to discharge the water vapor or dry dust in the lower vacuum filtration chamber 7. When discharging the water vapor in the lower vacuum filtration chamber 7, only need to open the manual ball valve 9. When discharging the dry dust in the lower vacuum filtration chamber 7, it is necessary to open the cover plate of the observation window 8 and connect a vacuum cleaner to the manual ball valve 9 to suck out the dry dust in the lower vacuum filtration chamber 7.

[0031] When the vacuum system component 3 starts working, it is positioned through the positioning and guiding component, and then the pipe pile is adsorbed by the rubber suction cup component 2. After the adsorption is in place, the traveling crane starts to transfer the pipe pile to the next working station, completing one working cycle. During this period, the dust on the surface of the pipe pile is sucked into the steel frame 1, and most of the dust is filtered out through this. A small amount of dust continues to travel along the vacuum filtration chamber inside the steel frame 1 and is finally absorbed by the filter set at the front end of the vacuum pump, completing the entire self-filtration process; during equipment maintenance, by opening the cover plate of the observation window 8, the cleanliness inside the steel frame 1 can be observed. The water vapor generated by the compressed air is discharged through the manual ball valve 9 set at the lower part of the steel frame 1. When the observation window 8 is opened, the dry dust is directly sucked out through the manual ball valve 9 connected to the vacuum cleaner, completing one cleaning process.

[0032] The above description is only a description of the preferred embodiments of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the art of the present invention based on the above disclosure are within the scope of protection of the claims.
