Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grinding equipment, in particular to a collection mechanism and a building grinding machine. Background Art
[0002] A building grinding machine is a power tool specifically used for building surface treatment. It mainly uses grinding media such as high-speed rotating grinding wheels or abrasive belts to grind and polish the surface of building materials, so as to achieve effects such as leveling, smoothing, removing impurities, and increasing adhesion.
[0003] During the daily maintenance of concrete buildings in giant hydropower stations, it is often necessary to apply clear water protective paint to the concrete surface. The most important first process is the base surface grinding treatment. The quality of the base surface grinding is directly related to the subsequent protective paint construction effect. However, for large inclined surfaces, vertical surfaces, and steep slopes such as the outlet of the flood discharge tunnel, the tail water working surface, and the pier, using human spider or scaffolding operations often has high risks and low efficiency. When grinding, the personnel cannot be stressed horizontally, resulting in poor grinding effects. Summary of the Utility Model

[0030] Next, the present utility model will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be locally enlarged in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.
[0031] Embodiment 1
[0032] Refer to Figure 1 - Figure 4 , which is the first embodiment of the present utility model, provides a collection mechanism. This device includes a device unit 100, which includes a drive motor 101, a first limiting plate 103 disposed on one side of the drive motor 101, spring limiting wheels 107 disposed around the first limiting plate 103, a third limiting plate 106 disposed at the bottom of the drive motor 101, and a spring button 105 disposed within the third limiting plate 106; and a collection unit 200, a collection frame 201 disposed on one side of the third limiting plate 106, and a second limiting plate 104 corresponding to the collection frame 201 is disposed on one side of the first limiting plate 103. The spring limiting wheels 107 provide reverse elastic force around the first limiting plate 103, preventing the grinding disc 102 from coming into contact with and rubbing against the first limiting plate 103 and the collection frame 201 during the grinding process, thereby reducing the wear degree of the first limiting plate 103 and the collection frame 201, and thus increasing the service life and use stability of the first limiting plate 103 and the collection frame 201.
[0033] Among them, the spring limiting wheel 107 includes a connecting plate 107a disposed on the first limiting plate 103, a spring column 107b disposed inside the connecting plate 107a, a fourth limiting plate 107c disposed at one end of the spring column 107b, and a universal wheel 107d disposed at one end of the fourth limiting plate 107c. The number of spring limiting wheels 107 is at least three, and the three spring limiting wheels 107 are evenly distributed around the first limiting plate 103. Multiple groups of spring columns 107b provide elastic force between the universal wheel 107d and the first limiting plate 103, and at the same time, the fourth limiting plate 107c limits it, further preventing the grinding disc 102 from coming into contact with and rubbing against the first limiting plate 103 and the collection frame 201 during the grinding process, thus increasing the service life and use safety of the first limiting plate 103 and the collection frame 201.
[0034] During use, when the grinding disc 102 grinds the grinding wall surface 304, since the four groups of negative pressure suction cups 108 around it will generate negative pressure suction force simultaneously, the grinding disc 102 can grind the grinding wall surface 304 smoothly. However, during the grinding process, as the grinding disc 102 grinds deeper, the limiting plate 103 around it will also move towards the grinding wall surface 304 side. Furthermore, the collection box 201 that is mutually clamped with the limiting plate 2 104 and the limiting plate 3 106 will also move towards the grinding wall surface 304 side. At this time, the spring limiting wheels 107 around the limiting plate 103 will also move with it, making the universal wheels 107d fit with the surface of the grinding wall surface 304. Under the maximum negative pressure suction force of the negative pressure suction cups 108, the spring columns 107b in the connecting plate 107a are at the maximum compression length at this time. Then, the spring columns 107b will provide a reverse elastic force for the grinding of the grinding disc 102. Furthermore, there is a certain distance between the limiting plate 103 around the grinding disc 102 and the grinding wall surface 304, and the distance range is between 0.2 cm and 0.8 cm. Thus, it is prevented that during the grinding process of the grinding disc 102, the grinding wall surface 304 will come into contact and friction with the limiting plate 103 and the collection box 201, which is not convenient for the up and down movement adjustment of the device unit 100. At the same time, the wear degree of the limiting plate 103 and the collection box 201 is reduced, and further, the service life and use stability of the limiting plate 103 and the collection box 201 are increased.
[0035] Embodiment 2
[0036] Refer to Figure 1 - Figure 4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: guide blocks 202 are provided on both sides of the collection box 201, a spring buckle 203 corresponding to the spring button 105 is provided on one side of the collection box 201, friction grooves 204 are equidistantly provided on both sides of the bottom of the collection box 201, and a card slot 205 is provided on the other side of the collection box 201. By means of the friction grooves 204, the friction force between the fingers of the staff and the collection box 201 is increased, so that the staff can firmly hold the collection box 201, preventing the staff from not firmly holding the collection box 201, resulting in the dust and debris inside it falling out, which is not convenient for the staff to clean up.
[0037] Compared with Embodiment 1, further, the size of the bottom of the collection box 201 is smaller than that of its upper part, which is convenient for the staff to hold the friction grooves 204 on both sides of its bottom with the palm, so as to take out the collection box 201 from between the limiting plate 2 104 and the limiting plate 3 106, further increasing the use comfort of the staff.
[0038] During use, first insert the collection box 201 along the bottom of the drive motor 101 between the second limiting plate 104 and the third limiting plate 106. At this time, the guiding blocks 202 on both sides of the collection box 201 will guide it, so that the collection box 201 can be accurately inserted into it. And at this time, the elastic buckle inside the second limiting plate 104 will be inserted into the spring button 105 on one side of the collection box 201, while the spring buckle 203 on one side of the collection box 201 will enter the spring button 105 along the sliding groove inside the third limiting plate 106 and engage with the spring button 105. Then, the drive motor 101 controls the grinding disc 102 to grind the grinding wall surface 304. Therefore, a certain amount of dust and debris will be generated around the grinding disc 102. At this time, the first limiting plate 103 above the grinding disc 102 will limit the dust and debris splashing above it, so that it can only fall downward and deposit, accumulating inside the collection box 201. After grinding for a period of time, the staff controls the electric hoist 302 to lower the steel cable 303, and then slowly lowers the equipment unit 100 to one side of the staff. At this time, the staff presses the spring button 105 on one side of the third limiting plate 106, so that the spring buckle 203 pops open. Then, the staff holds the friction grooves 204 on both sides of the bottom of the collection box 201, and then slowly takes out the collection box 201 along the guiding blocks 202 on both sides of it, and cleans the dust and debris accumulated in the collection box 201. After the cleaning is completed, repeat the above operations to collect the dust and debris generated by the grinding of the grinding disc 102 again, reduce the dust generated during the grinding construction of the grinding disc 102, prevent the dust from splashing and causing harm to the staff, and increase the safety and use comfort of the staff.
[0039] The rest of the structure is the same as that of Embodiment 1.
[0040] Embodiment 3
[0041] Refer to Figure 1 - Figure 5 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that it further includes a moving unit 300, which includes an I-shaped guide rail 301, an electric hoist 302 arranged on the I-shaped guide rail 301, a steel cable 303 arranged on the electric hoist 302, a grinding disc 102 arranged on one side of the drive motor 101, and a negative pressure fan 109 arranged around the drive motor 101. The electric hoist 302 moves left and right on the I-shaped guide rail 301, and the steel cable 303 rotates inside the electric hoist 302, so as to adjust and control the grinding area of the equipment unit 100 at the bottom of the steel cable 303 on the surface of the grinding wall surface 304, so as to facilitate the staff to grind the grinding wall surface 304 arbitrarily, and then increase the application range of the device and the use comfort of the staff.
[0042] Compared with Embodiment 2, further, the number of negative pressure suction cups 108 is four groups, and the four groups of negative pressure suction cups 108 are evenly distributed around the first limiting plate 103. Negative pressure is provided simultaneously around the grinding disc 102 through the four groups of negative pressure suction cups 108, so that the grinding disc 102 can be firmly pressed on the grinding wall surface 304 for grinding, thereby improving the grinding effect.
[0043] During the use process, the staff controls the electric hoist 302 to move left and right on the I-shaped guide rail 301, and controls the steel cable 303 to rotate within the electric hoist 302, so as to adjust and control the grinding area of the equipment unit 100 at the bottom of the steel cable 303 on the surface of the grinding wall surface 304, thereby facilitating the staff to perform arbitrary grinding on the grinding wall surface 304, increasing the application range of the device and the comfort of use for the staff; at the same time, when the grinding disc 102 grinds the grinding wall surface 304, the negative pressure fan 109 in the negative pressure suction cup 108 is started at this time to generate negative pressure suction, so that the negative pressure suction cup 108 adsorbs on the surface of the grinding wall surface 304, and then a certain pressure is generated between the grinding disc 102 and the protruding part of the surface of the grinding wall surface 304, so that the grinding disc 102 can evenly grind the surface of the grinding wall surface 304, thereby solving the problem that when the grinding disc 102 grinds, the staff cannot be stressed in the horizontal and vertical directions, resulting in poor grinding effect.
[0044] The rest of the structure is the same as that of Embodiment 2.
[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
