Description

Technical Field

[0001] This utility model belongs to the field of housing construction technology, specifically relating to a wall grinding device for housing construction. Background Technology

[0002] Housing construction includes the construction of various types of buildings and their ancillary facilities, the installation of supporting lines, pipes, and equipment, as well as interior and exterior decoration. Wall sanding is an indispensable step in the decoration process to ensure the quality and aesthetics of the walls. It not only affects the final decorative effect but also influences the lifespan and water resistance of the walls.

[0003] Chinese patent document CN219725556U discloses a wall grinding device for house construction. When the grinding disc contacts the wall, the contact strip contacts the wall, thereby achieving a sealing effect between the edge of the shield and the gap in the wall. This allows the air pump to fully draw the dust generated at the grinding disc into the exhaust gas treatment component, thereby absorbing the dust and reducing the possibility of the dust drifting to the surrounding area.

[0004] However, in the existing technology, although the grinding device can ensure the dust reduction effect, it is not easy to control the grinding amount to be consistent when grinding different parts of the wall, and it may leave dents or scratches on the wall. Therefore, a wall grinding device for building construction is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a wall grinding device for house construction.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A wall sanding device for building construction includes a sanding component that can sand the wall to the desired degree, a shifting component that can change the sanding position of the device on one side of the sanding component, and an adjusting component that can adjust the amount of sanding of the wall by the device on one side of the shifting component.

[0008] The spacing adjustment assembly includes a first abutment wheel disposed below the grinding assembly;

[0009] The sanding assembly includes a sanding component that can sand the wall after operation, a retraction component that allows the device to sand the wall according to a preset sanding amount while preventing the sanding component from bumping or scratching the wall, and a dust collection component that can limit the scattering of dust generated during sanding.

[0010] The retraction component includes a second support rod fixedly connected to one side of the displacement assembly. A bracket is fixedly connected to one end of the second support rod. A third support rod is movably connected to the bracket. A cover is fixedly connected to one side of the bracket. A spring is provided between the third support rod and the cover. A ring frame is fixedly connected to one end of the third support rod. A second screw is fixedly connected to the ring frame. A connector is fixedly connected to one end of the second screw. A second abutment wheel is movably connected to one side of the connector.

[0011] Preferably, the dust collection component includes a baffle fixedly connected to one side of the ring frame, and an insertion tube is fixedly connected to the outer side of the baffle.

[0012] Preferably, the grinding component includes a bearing seat fixedly installed inside the baffle, a rotating shaft movably connected to one side of the bearing seat, a grinding disc fixedly installed at one end of the rotating shaft, and a second motor fixedly connected to the other end of the rotating shaft.

[0013] Preferably, the bracket is slidably connected to the third support rod, and the joint is rotatably connected to the second abutment wheel.

[0014] Preferably, the tangent of the edge of the second abutting wheel away from the ring frame is coplanar with the side of the grinding disc away from the ring frame.

[0015] Preferably, the bearing seat is rotatably connected to the rotating shaft.

[0016] The beneficial effects of this utility model are as follows: by adjusting the horizontal position of the first abutting wheel, the dust collection component installed on one side of the ring frame and the grinding component installed in the dust collection component can be pushed a certain distance towards the wall by the spring as grinding progresses, so as to accurately complete the required amount of grinding on the wall. Combined with the setting of the second abutting wheel, the worker can avoid other parts from bumping or scratching the wall by the contact between each second abutting wheel and the wall and the degree of contact, and ensure that the grinding component is adjusted to a position that can fully contact the wall.

[0029] like Figures 1-6 As shown, a wall grinding device for building construction includes a grinding component 3 that can grind the wall to the required degree. A shifting component 1 that can change the grinding position of the device is provided on one side of the grinding component 3. An adjusting component 2 that can adjust the amount of grinding of the wall by the device is provided on one side of the shifting component 1.

[0030] In this embodiment: the shifting component 1 includes a frame 101, a roller 102 is fixedly installed under the frame 101, a handrail 103 is fixedly installed inside one side of the frame 101, a commutator 104 is movably installed inside the frame 101, an electric push rod 105 is provided between the frame 101 and the commutator 104, a support 106 is fixedly installed at the upper and lower ends of the commutator 104, a lead screw 107 is movably connected between the supports 106, a first motor 108 is fixedly connected at the lower end of the lead screw 107, and a lifting frame 109 is provided between the commutator 104 and the lead screw 107;

[0031] The frame 101 is rotatably connected to the commutator 104. Both the frame 101 and the commutator 104 are rotatably connected to the electric push rod 105. The support 106 is rotatably connected to the lead screw 107. The commutator 104 is slidably connected to the lifting frame 109. The lead screw 107 is connected to the lifting frame 109 by a thread.

[0032] The rollers 102 allow workers to easily push the frame 101 using the handrail 103, enabling the frame 101 to move components such as the reversing frame 104 and the first support rod 201 as needed. The tilt of the reversing frame 104, which is equipped with components such as the lifting frame 109, is adjusted by the operation of the electric push rod 105. The lead screw 107 is installed inside the reversing frame 104 via the support 106, allowing the lifting frame 109, which is also installed inside the reversing frame 104, to rise or fall within the reversing frame 104 when the rotation of the output end of the first motor 108 is transmitted to it by the lead screw 107.

[0033] In this embodiment: the adjustable distance component 2 includes a first support rod 201 movably connected to one side of the frame 101, a carrier plate 202 fixedly connected to one side of the first support rod 201, a first abutting wheel 203 fixedly installed on the carrier plate 202, a first screw 204 provided between the frame 101 and the carrier plate 202, and a knob 205 fixedly connected to one end of the first screw 204;

[0034] The frame 101 is slidably connected to the first support rod 201, the frame 101 is threadedly connected to the first screw 204, and the carrier plate 202 is rotatably connected to the first screw 204;

[0035] The carrier plate 202 is installed by the first support rod 201, so that the carrier plate 202 can drive the first abutment wheel 203 to move horizontally relative to the frame 101. The first abutment wheel 203 contacts the bottom area of ​​the wall where the baseboard is installed, so that the frame 101 and the wall can maintain a fixed distance. The first screw 204 can be easily rotated by the knob 205, so that the distance between the frame 101 and the carrier plate 202 can be changed when the first screw 204 rotates relative to the frame 101.

[0036] In this embodiment: the grinding component 3 includes a grinding component that can grind the wall surface after operation, a retraction component that allows the device to grind the wall surface according to a preset grinding amount while avoiding the grinding component from bumping or scratching the wall surface, and a dust collection component that can limit the scattering of dust generated during grinding. The retraction component includes a second support rod 301 fixedly connected to one side of the displacement component 1. One end of the second support rod 301 is fixedly connected to a bracket 302. A third support rod 303 is movably connected to the bracket 302. A cover 304 is fixedly connected to one side of the bracket 302. A spring 305 is provided between the third support rod 303 and the cover 304. One end of the third support rod 303... A ring frame 306 is fixedly connected, a second screw 307 is fixedly connected to the ring frame 306, a connector 308 is fixedly connected to one end of the second screw 307, a second abutment wheel 309 is movably connected to one side of the connector 308, a dust collection component includes a baffle 310 fixedly connected to one side of the ring frame 306, an insertion tube 311 is fixedly connected to the outer side of the baffle 310, and a grinding component includes a shaft seat 312 fixedly installed inside the baffle 310, a rotating shaft 313 is movably connected to one side of the shaft seat 312, a grinding disc 314 is fixedly installed at one end of the rotating shaft 313, and a second motor 315 is fixedly connected to the other end of the rotating shaft 313;

[0037] The bracket 302 is slidably connected to the third support rod 303, the joint 308 is rotatably connected to the second abutting wheel 309, the tangent of the edge of the second abutting wheel 309 away from the ring frame 306 is coplanar with the side of the grinding disc 314 away from the ring frame 306, and the bearing seat 312 is rotatably connected to the rotating shaft 313.

[0038] The bracket 302 and the lifting frame 109 are connected by the second support rod 301. The third support rod 303, which is not subjected to external force, can drive the ring frame 306 to tend to move away from the bracket 302 through the cover 304 and the spring 305. The second abutting wheel 309 is installed at a certain distance away from the bracket 302 on the side of the ring frame 306 through the second screw 307 and the connector 308, and the second abutting wheel 309 can rotate around the center line of the adjacent second screw 307. The baffle 310 provides an installation position for the bearing seat 312. The external dust collection equipment is connected through the insertion tube 311 to form a negative pressure inside the baffle 310 so as to continuously suck up the dust and debris dispersed around the grinding disc 314. The rotating shaft 313 for mounting the grinding disc 314 is installed inside the baffle 310 through the bearing seat 312. The rotation of the output end of the second motor 315 is transmitted to the grinding disc 314 through the rotating shaft 313.

[0039] Working principle: When this device is installed for wall sanding in house construction, the insertion tube 311 is connected to an external vacuum cleaner. Then, the frame 101 is moved to the vicinity of the wall to be sanded via the handle 103, and the first abutment wheel 203 is pressed firmly against the bottom area of ​​the wall. Then, depending on the slope of the wall, the tilt of the reversing frame 104 is adjusted by the operation of the electric actuator 105, ensuring that the sanding disc 314 is fully parallel to the wall. If it is not parallel, one of the second abutment wheels 309 surrounding the circumferential shield 310 will be the first to contact the wall when the sanding disc 314 subsequently moves towards it.

[0040] After adjustment, the first screw 204 can be rotated by knob 205 to adjust the horizontal distance between the frame 101 and the first abutment wheel 203. The adjustment is divided into two stages. In the first stage, each of the second abutment wheels 309 and the grinding disc 314, which is parallel to the wall, are in full contact with the wall, but the distance between the bracket 302 and the ring frame 306 remains unchanged. In the second stage, the distance between the bracket 302 and the ring frame 306 is reduced to a certain extent, and this change is the required amount of wall grinding.

[0041] After all the above adjustments are completed, the first motor 108 and the second motor 315 can be started. After starting, the first motor 108 can adjust the height of the lifting frame 109 through the lead screw 107. Combined with the change of position of the frame 101 by the operator, the grinding disc 314 can grind different positions on the wall. After the second motor 315 starts, it can drive the grinding disc 314 to rotate continuously and grind the wall.

[0042] Under the action of the compressed spring 305 in the second stage, the grinding disc 314 will slowly move towards the wall as the grinding progresses. When the spring 305 returns the ring frame 306 to the position it was in when the first stage was completed, it means that the device has completed the grinding of the wall according to the preset grinding amount.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
