Description

Technical Field

[0001] The utility model belongs to the technical field of concrete component grinding, and in particular relates to a concrete component grinding device. Background Art

[0002] Concrete components can be classified into prefabricated components and decorative components according to their functions. Prefabricated concrete components are concrete structures that are assembled / connected with prefabricated components as the main load-bearing components. Common prefabricated concrete components include: prefabricated exterior walls, prefabricated piles, prefabricated beams, prefabricated columns, prefabricated shear walls, prefabricated floor slabs, prefabricated stairs, prefabricated terraces, etc.

[0003] In the Chinese patent with publication number CN 211388182 U, a base, a shell, a driving device and a fixing device are included. The base and the driving device are both located inside the shell. The driving device is mounted on the base, and the driving device shaft extends outward to the outside of the top of the shell. The fixing device is fixedly mounted on the end of the shaft. A receiving cavity is provided on the fixing device, and the grinding tool is fixedly mounted in the receiving cavity. When grinding, only the power supply needs to be turned on, and the driving device drives the shaft to rotate, thereby driving the grinding tool to rotate, so that the grinding area to be grinded can be realized. The operation is convenient, manpower saving and high efficiency;

[0004] However, when the device is used to grind one side of a step-shaped concrete component, the device is inconvenient to hold. Specifically, when grinding a horizontal surface, the device is located on the upper side of the horizontal surface, and the grip is no different from normal. However, when grinding a vertical surface, due to the obstruction of the bottom of the step, most of the time, two methods are used for grinding. One of them is to grind with the handle on top and the grinding device on the bottom. During the grinding process, this posture is not convenient for checking the grinding progress and is prone to uneven grinding. The other is that the staff leans sideways to the side of the step surface for grinding, but for a long step, one arm cannot thoroughly grind the entire vertical surface of the step. The staff needs to frequently change positions on the two sides of the step, and the process is relatively complicated. Therefore, the present application proposes a grinding device for a concrete component, which can make the grinding of the step surface of a step-shaped concrete component more convenient.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 4 A grinding device for a concrete component comprises a concrete component body 1 and a grinding device body 2. The grinding device body 2 in the technical solution is mainly suitable for grinding a step-shaped concrete component body 1. The concrete component body 1 comprises a horizontal surface and a vertical surface. The existing grinding device is held in different directions during grinding the horizontal surface and the vertical surface, and needs to be frequently changed.

[0024] In a further embodiment, the grinding device body 2 is fixedly mounted on the bracket 3. Specifically, the grinding wheel 201 in the grinding device body 2 is located at the lower side of the bracket 3, and the upper end surface of the grinding wheel 201 is rotatably connected to the bracket 3. The bracket 3 is rotatably connected to the mounting seat 4 through a rotating shaft. The mounting seat 4 is fixedly connected to the handle 5. The handle 5 is provided with an anti-slip rubber sleeve. The bracket 3 rotates relative to the mounting seat 4 and has at least two states, wherein the two states are a horizontal surface grinding state and a vertical surface grinding state. In the horizontal surface grinding state, the bracket 3 fixedly connected to the grinding device body 2 is vertically distributed to the mounting seat 4. The horizontal surface grinding state is used to grind the horizontal surface of the concrete component body 1. In the vertical surface grinding state, the bracket 3 fixedly connected to the grinding device body 2 is parallelly distributed to the mounting seat 4. The vertical surface grinding state is used to grind the vertical surface of the concrete component body 1.

[0025] Specifically, the mounting seat 4 is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the bracket 3. Two threaded sleeves 6 are connected to the rotating shaft by threads. The two threaded sleeves 6 are respectively located on both sides of the mounting seat 4. The bracket 3 is rotated relative to the mounting seat 4 (or the mounting seat 4 and the handle 5 thereon are rotated) to adjust the relative position between the two. After the position is rotated to a suitable position, the two threaded sleeves 6 are twisted to make the two threaded sleeves 6 respectively rest on the two side surfaces of the mounting seat 4, and the relative position between the bracket 3 and the mounting seat 4 is kept fixed by friction force to fix its state;

[0026] In a further embodiment, Figure 4 As shown, when the vertical surface is being polished, the handle 5 and the bracket 3 are in a parallel state, and it is inconvenient to apply force by lifting and pulling down, and the polishing process may be laborious. In order to reduce the burden when polishing the vertical surface, an auxiliary frame 7 is installed on the bracket 3 for assisting personnel to polish the vertical surface. The auxiliary frame 7 is fixedly connected to the rotating shaft. The two auxiliary frames 7 are respectively installed on both sides of the bracket 3, and the auxiliary frames 7 are fitted with the side walls of the bracket 3. A retractable rod 8 is inserted in the auxiliary frame 7, and the retractable rod 8 is slidably connected to the guide sleeve 9. A fixing frame 10 is fixedly installed on the end of the guide sleeve 9 away from the retractable rod 8. The fixing frame 10 An auxiliary wheel 11 is rotatably installed on the upper part. When grinding the vertical surface, the auxiliary wheel 11 is against the horizontal plane of the concrete component body 1. When the handle 5 is pulled left and right and the height of the handle 5 and the grinding device body 2 is adjusted up and down, the spring can reduce the difficulty of lifting to a certain extent, and reduce the burden when grinding the vertical surface. A spring is sleeved on the outer side of the retractable rod 8. In order to prevent the retractable rod 8 from slipping out of the guide sleeve 9, the retractable rod 8 is set in an I-shape, and the size of the two ends is larger than the size of the middle part. The middle part is slidably connected with the guide sleeve 9, and the two ends are used to prevent it from leaking out of the guide sleeve 9 or the auxiliary frame 7;

[0027] When the horizontal surface is being polished, the auxiliary wheel 11 faces one side of the handle 5 and can move relative to the bracket 3. During the horizontal surface polishing process, the auxiliary wheel 11 may collide with the hand. Therefore, a blocking plate 12 is installed on the handle 5. When the horizontal surface is being polished, the auxiliary wheel 11 rests on the blocking plate 12.

[0028] Working principle:

[0029] The bracket 3, the mounting seat 4 and the handle 5 are designed to be adjustable, and the angle between the bracket 3 and the mounting seat 4 can be adjusted as needed. For the grinding work of the stepped concrete component body 1, the personnel do not need to adjust their body position left and right, so that Figure 1 For example, from bottom to top, the horizontal surface and the vertical surface of the concrete component body 1 can be polished in sequence, and the polishing work of the step side of the concrete component body 1 can be completed on the front side of the concrete component body 1, which is more time-saving and labor-saving;

[0030] The bracket 3 is provided with an auxiliary frame 7 and other components, which can support the ground when the vertical surface is being polished. The polishing device body 2 is more labor-saving when moving upward, and the operation is more convenient.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
