Description

Technical Field

[0001] This utility model belongs to the technical field of grinding devices, specifically relating to a concrete floor grinding device. Background Technology

[0002] Traditional grinding machines present significant challenges in controlling the levelness during operation. Because the grinding machine travels along the concrete surface and performs the grinding process, the unevenness of its travel path and the inconsistency of the grinding force make it difficult to achieve the required high levelness after grinding.

[0003] Especially in localized areas, such as joints in formwork or uneven concrete pouring, grinding machines struggle to make precise adjustments, easily resulting in uneven surfaces. Furthermore, traditional grinding machines often require multiple adjustments and rework to meet the stringent levelness requirements of subsequent equipment installation or use, which not only increases construction costs but also reduces efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a concrete floor grinding device that moves along a leveling support rail, thereby effectively ensuring the overall levelness of the floor.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A concrete floor grinding device includes a support guide rail frame, a movable frame, and a grinding carriage; the support guide rail frame includes an adjusting wedge and a pair of guide rails, the pair of guide rails being fixedly connected by a connecting rod, the adjusting wedges being connected to the guide rails, and each guide rail being connected to at least two adjusting wedges; the movable frame is provided with a first traveling wheel that cooperates with the pair of guide rails, and the movable frame moves horizontally along the pair of guide rails.

[0007] The grinding frame is equipped with a second traveling wheel that cooperates with the moving frame. Positioning baffles that cooperate with the moving frame are fixedly connected to both sides of the grinding frame. The grinding frame moves horizontally and longitudinally along the moving frame. A grinding machine is fixed on the grinding frame.

[0008] The connecting rod and the guide rail are fixedly connected by bolts.

[0009] The grinding frame has two second travel wheels on one side and one second travel wheel on the other side.

[0010] The grinding machine is connected to the grinding frame via a bolted connection assembly. The bolted connection assembly includes a connecting plate, a connecting bolt, and a connecting nut. The connecting plate is fixedly connected to the grinding machine. The end of the connecting bolt passes through the connecting plate and the grinding frame in sequence. There are three connecting nuts, all of which are connected to the connecting bolt. The three connecting nuts are arranged sequentially from top to bottom. The grinding frame is clamped by the two connecting nuts located at the top, and the connecting plate is clamped by the connecting nut located at the bottom and the head of the connecting bolt.

[0011] The mobile frame includes a pair of horizontal bars and a vertical bar, with the pair of horizontal bars connected by the vertical bar to form a square frame after connection;

[0012] The crossbar includes an upper crossbar and a lower crossbar, and the two sides of the upper crossbar and the lower crossbar are fixedly connected by channel steel; there is a gap in the middle of the upper crossbar and the lower crossbar.

[0013] A deflection adjustment assembly is provided between the middle of the upper crossbar and the lower crossbar. The deflection adjustment assembly includes an upper connecting piece, a lower connecting piece, and an adjusting bolt. The upper connecting piece is fixedly connected to the upper crossbar, and the lower connecting piece is fixedly connected to the lower crossbar.

[0014] One end of the adjusting bolt passes through the lower connecting piece and the upper connecting piece in sequence. The adjusting bolt is connected to three adjusting nuts from top to bottom. The lower connecting piece is located between the head of the adjusting bolt and the smallest adjusting nut, and the upper connecting piece is located between the other two adjusting nuts.

[0015] The adjusting wedge includes a fixed base, a fixed wedge block, and a movable wedge block. The movable wedge block is slidably connected to the fixed base. An adjusting bolt is rotatably connected to the fixed base. The movable wedge block is threadedly connected to the adjusting bolt. The fixed wedge block is slidably connected to the adjusting bolt. The fixed wedge block is provided with a corresponding sliding groove.

[0016] The fixed inclined block is provided with a limiting groove, through which it is slidably connected to the guide rail.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] This grinding device is equipped with a support guide rail and a moving frame. The levelness of the support guide rail is adjusted by adjusting the wedge. That is, during the grinding process, the grinder moves based on the support guide rail and the moving frame, rather than the ground, thus overcoming the defect of poor levelness after grinding caused by uneven ground.

[0019] The bolted connection assembly can be used to adjust the height of the grinder. The deflection adjustment assembly can support the upper and lower crossbars and allow for deflection adjustment.

[0020] The adjustable wedge's structural design allows for height adjustment simply by moving the movable wedge block, thus regulating the levelness of the support rail frame. The limiting groove design effectively prevents the adjustable wedge from moving unnecessarily. Attached Figure Description

Detailed Implementation

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0030] like Figure 1-7 As shown, a concrete floor grinding device includes a support guide frame 1, a movable frame 2, and a grinding carriage 3. The support guide frame 1 includes an adjusting wedge 4 and a pair of guide rails 5, which are fixedly connected by connecting rods 6, specifically by two connecting rods 6. The guide rails 5 are preferably steel rails.

[0031] Adjusting wedges 4 are connected to guide rails 5. Each guide rail 5 is connected to at least two adjusting wedges 4. The levelness of the guide rail 5 is adjusted by adjusting the wedges 4. A first traveling wheel 7 is provided on the movable frame 2 to cooperate with a pair of guide rails 5. The first traveling wheel 7 is supported on the guide rails 5. The movable frame 2 moves horizontally (back and forth) along a pair of guide rails 5. The first traveling wheel 7 can be a track wheel. The first traveling wheel 7 is rotatably connected to the movable frame 2.

[0032] A second traveling wheel 8 is provided on the grinding frame 3 to cooperate with the moving frame 2, and the second traveling wheel 8 is supported on the moving frame 2; positioning baffles 11 that cooperate with the moving frame 2 are fixedly connected on both sides of the grinding frame 3, and the horizontal (forward and backward) movement of the grinding frame 3 can be restricted by the positioning baffles 11; that is, the grinding frame 3 can only move horizontally (left and right) along the moving frame 2; a grinding machine 12 is fixed on the grinding frame 3.

[0033] During the setup and installation phase: Based on the site plan, select a certain number of adjusting wedges 4. Lay guide rails 5 on the wedges 4, and connect and fix the two guide rails 5 using connecting rods 6. Then, adjust the height of the wedges 4 to align the two guide rails 5 within a horizontal plane that meets the requirements. Next, place the movable frame 2 on the guide rails 5, ensuring smooth movement of the movable frame 2. Finally, place the grinding frame 3 on the movable frame 2, ensuring it can move smoothly in the specified direction.

[0034] Operational phase: Powering on the grinder 12 initiates grinding operation. The moving frame 2 moves horizontally (back and forth) along a pair of guide rails 5, while the grinding carriage 3 moves horizontally (left and right) along the moving frame 2 to perform the grinding work. The length of the guide rails 5 determines the length of the grinding range, and the length of the moving frame 2 determines the width of the grinding range. The levelness of the supporting guide rails 1 and the moving frame 2 determines the overall levelness of the ground.

[0035] The aforementioned pushing process is preferably carried out manually, which is simpler, more reliable, and safer; of course, the first traveling wheel 7 and the second traveling wheel 8 can be driven by electric track wheels as needed, i.e., driven by electric means.

[0036] Device dismantling phase: After construction is completed, dismantle the device in the reverse order of installation.

[0037] Furthermore, the connecting rod 6 and the guide rail 5 are fixedly connected by bolts.

[0038] Furthermore, it is preferable to have two second travel wheels 8 on one side of the grinding frame 3 and one second travel wheel 8 on the other side.

[0039] Furthermore, the outer casing of the grinder 12 is connected to the grinder frame 3 via bolted connection assembly 9. The distance between the grinder 12 and the concrete floor can be adjusted via the bolted connection assembly 9. The number of bolted connection assemblies 9 can be set according to actual conditions, and preferably four are provided.

[0040] The bolt connection assembly 9 includes a connecting piece 90, a connecting bolt 91, and a connecting nut 92. The connecting piece 90 is fixedly connected to the grinder 12. The end of the connecting bolt 91 passes through the connecting piece 90 and the grinder frame 3 in sequence. The connecting piece 90 and the grinder frame 3 are provided with corresponding connecting through holes.

[0041] There are three connecting nuts 92, all of which are connected to the connecting bolts 91. The three connecting nuts 92 are arranged sequentially from top to bottom. The grinding frame 3 is clamped by the two connecting nuts 92 located at the top, and the connecting piece 90 is clamped by the connecting nut 92 located at the bottom and the head of the connecting bolt 91.

[0042] When it is necessary to adjust the height of the grinder 12 upwards: first rotate the uppermost connecting nut 92 counterclockwise to create a gap between it and the grinder frame 3; then rotate the middle connecting nut 92 counterclockwise, which will move the grinder 12 upwards to the specified height; finally, tighten the uppermost connecting nut 92 clockwise.

[0043] When it is necessary to adjust the height of the grinder 12 downwards: first rotate the middle connecting nut 92 clockwise, and the grinder 12 will move down under the action of gravity. After it moves down to the required height, tighten the uppermost connecting nut 92 clockwise.

[0044] Furthermore, the movable frame 2 includes a pair of horizontal bars and vertical bars 22. The pair of horizontal bars are connected by the vertical bars 22, forming a square frame after connection. The vertical bars 22 are fixed to the pair of horizontal bars by welding.

[0045] The crossbar includes an upper crossbar 20 and a lower crossbar 21, which are fixedly connected on both sides by channel steel 23; there is a gap in the middle of the upper crossbar 20 and the lower crossbar 21. A deflection adjustment assembly 10 is provided between the middle of the upper crossbar 20 and the lower crossbar 21, and the deflection between the upper crossbar 20 and the lower crossbar 21 is adjusted by the deflection adjustment assembly 10. The number of deflection adjustment assemblies 10 is set according to the actual situation.

[0046] The deflection adjustment assembly 10 includes an upper connecting piece 100, a lower connecting piece 101 and an adjusting bolt 102. The upper connecting piece 100 is fixedly connected to the upper crossbar 20, and the lower connecting piece 101 is fixedly connected to the lower crossbar 21.

[0047] One end of the adjusting bolt 102 passes through the lower connecting piece 101 and the upper connecting piece 100 in sequence. The adjusting bolt 102 is connected to three adjusting nuts 103 from top to bottom. The lower connecting piece 101 is located between the head of the adjusting bolt 102 and the smallest adjusting nut 103, and the upper connecting piece 100 is located between the other two adjusting nuts 103.

[0048] To adjust the deflection, simply change the position of the two upper adjusting nuts 103. By changing the position of the two upper adjusting nuts 103, the distance between the middle parts can be adjusted.

[0049] When it is necessary to increase the distance between the middle parts and make the middle part arch: first rotate the uppermost adjusting nut 103 counterclockwise to create a gap between it and the upper connecting piece 100; then rotate the middle adjusting nut 103 counterclockwise, which will cause the upper connecting piece 100 to move upward to increase the distance between the middle parts; finally, tighten the uppermost adjusting nut 103 clockwise.

[0050] No gap is required between the upper crossbar 20 and the lower crossbar 21; however, any horizontal steel structure will sag and bend downwards due to gravity. Therefore, the method of achieving a central arch by using the aforementioned deflection adjustment component is the simplest and most convenient, and can solve the sag and bending problem to the greatest extent.

[0051] Furthermore, the adjusting wedge 4 includes a fixed base 40, a fixed wedge block 41, and a movable wedge block 42. The movable wedge block 42 is slidably connected to the fixed base 40. An adjusting bolt 43 is rotatably connected to the fixed base 40. The movable wedge block 42 is threadedly connected to the adjusting bolt 43. The fixed wedge block 41 is slidably connected to the adjusting bolt 43. The fixed wedge block 41 is provided with a corresponding groove 44. Specifically, one end of the adjusting bolt 43 passes through the groove 44 and is fixedly connected to a baffle 46.

[0052] The position of the movable inclined block 42 can be changed by rotating the adjusting bolt 43, thereby changing the height of the guide rail 5.

[0053] Furthermore, to prevent the adjusting wedge from moving, a limiting groove 45 is provided on the fixed wedge 41, through which it is slidably connected to the guide rail 5.

[0054] The above description only describes the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments.
