Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding equipment technology, and in particular to a floor grinding device for factory construction. Background Technology
[0002] Factory concrete floors are industrial flooring systems made primarily of cement and aggregates, formed through processes such as pouring, compaction, and finishing. They possess characteristics such as high load-bearing capacity and wear resistance, making them suitable for industrial production, logistics warehousing, and other scenarios.
[0003] Currently, a Chinese patent discloses a concrete floor grinding machine (authorization announcement number CN222537133U). It uses four universal wheels and a support frame to keep the grinding head parallel to the ground. The mounting box and motor are pushed by a telescopic cylinder, and the slider moves downward along the slide rod, so that the grinding head touches the ground and grinds the ground. The grinding stroke is simple, direct and efficient.
[0004] During the operation of the above-mentioned equipment, the grinding head directly grinds the concrete floor. However, the equipment does not have any dust suppression structure. This makes it easy for the dust generated by the grinding head to adhere to the surface of the slide rod and the output shaft of the telescopic cylinder. This increases the lifting and adjusting resistance of the grinding equipment, and in severe cases, it may even jam the grinding equipment, preventing it from lifting and lowering normally. Utility Model Content
[0005] Therefore, it is necessary to provide a floor grinding device for factory construction, which addresses the problems of poor self-protection performance and low practicality of existing floor grinding devices.
[0006] A floor grinding device for factory construction includes: a movable base frame, a top cover, and a protective mechanism. The movable base frame and the top cover are fixedly connected to a mounting column. A mounting box is slidably fitted on the surface of the mounting column. An electric cylinder is fixedly connected to the top of the top cover and is fixedly connected to the mounting box. An electric grinder is installed inside the mounting box, and the output end of the electric grinder extends to the outside of the mounting box.
[0007] In one embodiment, the protective mechanism includes a first rubber bellows and a second rubber bellows. The first rubber bellows is fixedly connected between the top cover and the mounting box. The output shaft of the electric cylinder is located inside the first rubber bellows, and the second rubber bellows is sleeved on the surface of the mounting column.
[0008] In one embodiment, the ratio of the number of second rubber corrugated pipes to the number of mounting columns is 2:1. The two ends of the second rubber corrugated pipes located above the mounting box are fixedly connected to the top cover and the mounting box, respectively. The two ends of the second rubber corrugated pipes located below the mounting box are fixedly connected to the movable bottom frame and the mounting box, respectively.
[0009] In one embodiment, the protective mechanism further includes a dust cover fixedly connected to the bottom of the mounting box, the electric grinder being disposed inside the dust cover, and the lowest point of the electric grinder being disposed below the dust cover.
[0010] In one embodiment, the protective mechanism further includes a dust removal component, which includes a vacuum cleaner fixedly connected to the outside of the mounting box. The air inlet of the vacuum cleaner is fixedly connected to and communicates with a vacuum hose, and the air inlet of the vacuum hose extends into the interior of the dust cover and is fixedly connected to the dust cover.
[0011] In one embodiment, there are two vacuum hoses, which are symmetrically distributed on both sides of the electric grinder.
[0012] In one embodiment, the air outlet of the vacuum hose is fixedly connected to a threaded connector, one end of which is detachably connected to and communicates with the vacuum cleaner.
[0013] In one embodiment, the two opposite vertical inner walls of the mounting box are provided with heat dissipation vents, and a dustproof mesh is embedded inside the heat dissipation vents. Beneficial effects
[0014] The aforementioned floor grinding device for factory construction effectively isolates the electric cylinder output shaft and mounting column from the outside world through the synchronous expansion and contraction of the first and second rubber bellows, ensuring that the moving parts are not contaminated by dust during height adjustment, significantly reducing the lifting resistance of the electric grinder, extending the service life of the electric cylinder, and significantly improving the reliability of the equipment in dusty environments.
[0015] Multi-stage filtration system for dust removal components: The vacuum cleaner adopts a three-stage filtration system of cyclone separator cone + multi-layer dust bag + HEPA filter element, combined with symmetrically distributed suction hoses, which can effectively capture grinding dust. The synergistic effect of dust cover and dust removal components reduces the dust rate in the work area by %, meeting industrial environmental protection standards. Attached Figure Description

[0028] The following is combined with Figures 1-4 This invention describes a floor grinding device for factory construction.
[0029] In one embodiment, a floor grinding device for factory construction includes: a movable base frame 100, a top cover 200, and a protective mechanism 700. The movable base frame 100 and the top cover 200 are fixedly connected to a mounting column 300. A mounting box 400 is slidably fitted on the surface of the mounting column 300. An electric cylinder 500 is fixedly connected to the top of the top cover 200 and is fixedly connected to the mounting box 400. An electric grinder 600 is installed inside the mounting box 400, and the output end of the electric grinder 600 extends to the outside of the mounting box 400.
[0030] The electric grinder 600 includes, but is not limited to, the following structures:
[0031] Power system: The main motor is fixedly connected to the bottom wall of the mounting box 400 by bolts;
[0032] Grinding system: The diamond grinding disc and rubber connector buffer device are installed inside the dust cover 730. The main motor and the diamond grinding disc are coaxially connected through the rubber connector buffer device.
[0033] Control system: depth adjustment handle, dual independent switches and overload protection circuit breaker located on the top of the top cover 200;
[0034] The operating procedure of the 600 electric grinder: The main motor is actively driven to generate rotational power. The motor drives the grinding disc to rotate through the rubber connector buffer device. The diamond grinding head contacts the ground to generate friction. The grinding depth is controlled by adjusting the handle. The overload protection circuit breaker automatically cuts off the power supply in case of overload.
[0035] The mounting box 400 has heat dissipation vents 410 on its two opposite vertical inner walls, and a dustproof mesh 800 is embedded inside the heat dissipation vents 410.
[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the protective mechanism 700 includes a first rubber bellows 710 and a second rubber bellows 720. The first rubber bellows 710 is fixedly connected between the top cover 200 and the mounting box 400. The output shaft of the electric cylinder 500 is located inside the first rubber bellows 710. The second rubber bellows 720 is sleeved on the surface of the mounting post 300.
[0037] The ratio of the number of the second rubber corrugated pipe 720 to the number of the mounting column 300 is 2:1. The two ends of the second rubber corrugated pipe 720 located above the mounting box 400 are fixedly connected to the top cover 200 and the mounting box 400, respectively. The two ends of the second rubber corrugated pipe 720 located below the mounting box 400 are fixedly connected to the movable bottom frame 100 and the mounting box 400, respectively.
[0038] When the operator drives the electric cylinder 500 to adjust the height of the mounting box 400 and the electric grinder 600, the mounting box 400 simultaneously extends and retracts the first rubber bellows 710 and the second rubber bellows 720. This effectively covers the parts of the electric cylinder 500's output shaft and the mounting column 300 that are exposed outside the mounting box 400, allowing both the electric cylinder 500 and the mounting column 300 to operate in a clean environment, thus reducing the difficulty of adjusting the height of the electric grinder 600.
[0039] The protective mechanism 700 also includes a dust cover 730, which is fixedly connected to the bottom of the mounting box 400. The electric grinder 600 is located inside the dust cover 730, with the lowest point of the electric grinder 600 positioned below the dust cover 730. The dust cover 730 can prevent the electric grinder 600 from scattering the dust it produces in all directions without affecting the normal dust collection of the dust removal component 740 below, thereby reducing the dust emission rate to the surrounding area.
[0040] like Figure 2 and Figure 4As shown, the protective mechanism 700 also includes a dust removal component 740, which includes a vacuum cleaner 741 fixedly connected to the outside of the mounting box 400. The air inlet of the vacuum cleaner 741 is fixedly connected to and communicates with a vacuum suction hose 742. The air inlet of the vacuum suction hose 742 extends into the interior of the dust cover 730 and is fixedly connected to the dust cover 730.
[0041] There are two vacuum hoses 742, which are symmetrically distributed on both sides of the electric grinder 600.
[0042] The air outlet of the vacuum hose 742 is fixedly connected to a threaded connector 743, and one end of the threaded connector 743 is detachably connected to and communicates with the vacuum cleaner 741.
[0043] Vacuum cleaner 741 includes, but is not limited to, the following structures:
[0044] Outer shell: A metal mounting cylinder is fixedly connected to the outside of the mounting box 400 by clamps. The top of the metal mounting cylinder is threaded with a sealing cap. The sealing cap and the vacuum hose 742 are detachably connected by a threaded connector 743.
[0045] Power system: Rear-mounted turbine motor installed on the bottom wall of the metal mounting cylinder;
[0046] Dust collection assembly: A removable transparent dust chamber that inserts into the inside of a metal mounting cylinder.
[0047] Filtration system: The removable transparent dust chamber is equipped with a pre-filter, a cyclone separator cone, a multi-layer dust bag, and a HEPA post-filter, installed from top to bottom on the inner wall.
[0048] The working process of vacuum cleaner 741: When vacuum cleaner 741 is started, dusty air is first sucked into the metal mounting cylinder through the suction hose 742, and then passes through the pre-filter metal screen to filter large particles; then the airflow enters the cyclone separator cone, where centrifugal force throws out some dust particles, and the remaining fine dust continues to flow to the multi-layer dust bag, where the non-woven fabric adsorbs most of the suspended particles. Finally, the air passes through the HEPA filter to thoroughly filter micron-sized particles such as PM2.5. The purified air flows through the rear turbine motor for cooling and is then discharged from the exhaust port, completing the entire dust removal cycle.
[0049] It should be noted that the electric cylinder 500, electric grinder 600 and vacuum cleaner 741 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the electric cylinder 500, electric grinder 600 and vacuum cleaner 741 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.
[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
