Description

Technical Field

[0001] The invention relates to the technical field of scaffolds and formwork, in particular to a device and process for dismantling a building wall. Background Art

[0002] When demolishing a building wall, it is necessary to cut the building wall through a demolition device to facilitate the rapid demolition of the building wall. The demolition device is a special cutting tool suitable for cutting hard materials such as reinforced concrete, rock, ceramics and brick walls. The demolition device uses a high-speed rotating diamond cutting blade for cutting. Technical inspiration for the demolition device; Research into the removal device found the following issues: The demolition device usually cuts and demolishes the building wall by means of rotary cutting or impact cutting. Since the wall is made of concrete and bricks, a large amount of dust is easily splashed during the cutting and demolition process. At the same time, after the wall is impacted, the concrete on the wall surface is easy to splash. When the concrete splashes onto the surface of the cutting blade, it is easy to damage the surface of the cutting blade. At the same time, the high-speed rotating cutting blade drives the concrete to splash, which is easy to cause injuries to the workers. At present, CN202310562856.7 in the prior art discloses a wall demolition device, which solves the problem that the existing wall demolition requires manual hand-held tool operation, which is labor-intensive and difficult to demolish for higher walls, and the wall demolition equipment is prone to damage or injury when operating without load. The driving component and the impact component are installed inside the installation component, so there is no need for manual hand-holding, which reduces the labor intensity of workers, and the impact component can complete the function of cyclic impact on the wall to be demolished under the drive of the driving component. The device has a safety anti-no-load function, that is, when the safety block does not contact the wall in place, the impact component cannot be driven by the driving component to realize the impact wall demolition operation, and the impact force of the device during wall demolition can be freely adjusted for use; The present invention can mainly solve the problem that the removal device cannot protect the cutting blade while preventing dust from splashing. Summary of the invention

[0003] The purpose of the present invention is to provide a building wall demolition device and process.

[0004] To achieve the above object, the present invention provides the following technical solutions: The device and process for demolishing building walls include a base, the upper end of which is slidably and telescopically connected to a hydraulic push rod, a bracket is provided on the side of the hydraulic push rod, a motor is installed on the upper end of the bracket, and a cutting blade is rotatably connected to the side of the motor.

[0005] As a further solution of the present invention: a track is provided at the upper end of the base, and the hydraulic push rod slides in a vertical direction on the inner side of the track. When the hydraulic push rod slides in the vertical direction, the bracket slides synchronously.

[0006] As a further solution of the present invention: the motor and the hydraulic push rod are connected to the power circuit through a power line, and the motor drives the cutting blade to rotate 360 ​​degrees at a high speed.

[0007] As a further solution of the present invention: the side of the upper end of the hydraulic push rod is rotatably connected to an extension bearing, the upper and lower ends of the extension bearing are swingably connected to a support frame and a guide block, the outer side of the support frame is surrounded by a clamping block, and the end of the support frame away from the extension bearing is slidably connected to a shell.

[0008] As a further solution of the present invention: the shell is in a semicircular arc shape, the shell surrounds the outer side of the cutting blade, a slide groove 1 is opened on one side of the shell, and a slide groove 2 is opened on the other side of the shell close to the support frame.

[0009] As a further solution of the present invention: the support frame and the extension bearing are combined into a "Z" shape as a whole.

[0010] As a further solution of the present invention: the support frame is slidably nested and connected with the second slide groove of the shell, and the support frame is nested and fixed with the two ends of the slide groove of the shell. The overall weight of the support frame and the shell is less than the weight of the guide block by 300-400g.

[0011] As a further solution of the present invention: the card blocks are all nested inside the second slide groove of the shell.

[0012] As a further solution of the present invention: a protective ring is slidably connected to the outer side of the shell, a sliding ring is provided on one side of the protective ring close to the first slide groove of the shell, and a cushion block is embedded on the inner side of the sliding ring.

[0013] As a further solution of the present invention: the sliding ring is slidably nested and connected to the inner side of the slide groove 1 of the shell, the length of the sliding ring is one third of the length of the slide groove 1, and the protective ring is slidably connected to the shell through the sliding ring.

[0014] As a further solution of the present invention: the slide grooves of the sliding ring and the housing are both arranged in an arc shape, a groove is provided on the inner side of the sliding ring, the pads are respectively located on the inner side of the groove, and the ends of the pads extend to one end of the sliding ring.

[0015] As a further solution of the present invention: the pads are evenly arranged on the inner side of the sliding ring, there are 5 to 10 pads, and the pads are made of a deformable material, such as rubber.

[0016] As a further solution of the present invention: the process comprises the following steps: S1: The hydraulic push rod drives the bracket to adjust the height vertically, and then the motor drives the cutting blade to rotate 360 ​​degrees. The cutting blade can cut and remove the building wall; S2: By manually pushing the shell, the second slide slot of the shell slides 180° at one end of the support frame, which is convenient for adjusting the direction of the shell, so that the shell can be adjusted according to the cutting direction required by the cutting blade; S3: The demolition device cuts and demolishes the wall. When concrete falls to the upper end of the cutting blade during the cutting process, the concrete first hits the upper end of the protective ring, and the pad inside the protective ring is impacted, and the pad is deformed toward the inner side of the groove of the sliding ring; S4: The sliding ring is connected to the housing through the gasket. When the gasket is deformed, the sliding ring and the protective ring can slide on the outside of the housing as a whole. S5: Since there are 5 to 10 pads, after multiple collisions, the pads are gradually embedded in the grooves of the sliding ring; S6: The housing swings downward synchronously due to the impact, and the housing and the protective ring are both in an arc shape. The housing can swing in an arc shape through the support frame with the extended bearing as the center point. When the housing swings, the guide block is driven to swing upward through the extended bearing; S7: By utilizing the weight difference of the guide block, after the guide block swings upward, the guide block can return to its original position by extending the bearing, and the housing can return to its original position after being hit. Beneficial Effects

[0017] 1. The overall weight of the support frame and the housing is 5-10kg less than the weight of the guide block. Therefore, the housing and the support frame are located at the upper end of the extended bearing, and the guide block is located at the lower end of the extended bearing. Therefore, the weight difference between the guide block and the support frame is utilized. At this time, the support frame is in a stationary state; 2. By manually pushing the shell, the second slide groove of the shell slides 180° at one end of the support frame, which is convenient for adjusting the direction of the shell. Therefore, the shell can be adjusted according to the cutting direction required by the cutting blade. The shell is semicircular and surrounds the outside of the cutting blade. When the cutting blade cuts the wall, the dust splashing generated by the cutting blade can be reduced. The shell can be used to protect the cutting end of the cutting blade; 3. As the demolition device cuts and demolishes the wall, when concrete falls to the upper end of the cutting blade during the cutting process, the concrete first hits the upper end of the protective ring, and the pad inside the protective ring is impacted, and the pad is deformed toward the inner side of the groove of the sliding ring; 4. Since the sliding ring is connected to the outer shell through the pad, when the pad is deformed, the sliding ring and the protective ring can slide on the outer side of the outer shell as a whole. Since there are 5-10 pads, after multiple collisions, the pads are gradually embedded in the groove of the sliding ring, so that the outer shell and the cutting piece can be protected by the protective ring; 5. The housing swings downward synchronously due to the impact, and the housing and the protective ring are both in an arc shape. The housing can swing in an arc shape through the support frame with the extended bearing as the center point. When the housing swings, the guide block is driven to swing upward through the extended bearing. By utilizing the weight difference of the guide block, after the guide block swings upward, the guide block can return to its original position through the extended bearing, and the housing can return to its original position after being impacted, so that the housing can prevent dust from splashing during the cutting process while protecting the cutting disc; 6. Through the above steps, the cutting blade can be protected by the outer shell and the protective ring during the cutting process to prevent concrete fragments from falling onto the surface of the cutting blade after cutting. The high-speed rotation of the cutting blade may cause concrete fragments to splash. At the same time, the outer shell surrounds the outside of the cutting blade to prevent dust from splashing at the cutting end of the cutting blade, thus preventing dust from splashing during the cutting process.

[0027] See also Figure 1-8 In the embodiment of the present invention, Embodiment 1: A building wall demolition device and process, comprising a base 1, the upper end of which is slidably and telescopically connected to a hydraulic push rod 101, a side of which is provided with a bracket, an upper end of which is mounted a motor 103, and a side of which is rotatably connected to a cutting blade 102; Wherein: a base 1, the upper end of the base 1 is provided with a track, a hydraulic push rod 101 slides vertically on the inner side of the track, and when the hydraulic push rod 101 slides vertically, the bracket slides synchronously; A bracket is provided on the side of the hydraulic push rod 101, and a motor 103 is installed on the upper end of the bracket. Figure 2 and 3 As shown; One end of the hydraulic push rod 101 is connected to the hydraulic pump; The motor 103 and the hydraulic push rod 101 are connected to the power supply circuit through a power line, and the motor 103 drives the cutting blade 102 to rotate 360 ​​degrees at a high speed; The cutting blade 102 is a diamond cutting blade; Wherein: the hydraulic push rod 101 drives the bracket to adjust the height in the vertical direction as a whole, and then the motor 103 drives the cutting blade 102 to rotate 360 ​​degrees, and the cutting blade 102 can cut and remove the building wall; Example 2: Refer to the attached manual Figure 1-4 As can be seen from Figures 6 and 7, the difference between Example 2 and Example 1 is that the side surface of the upper end of the hydraulic push rod 101 is rotatably connected to the extension bearing 2, the upper and lower ends of the extension bearing 2 are swingably connected to the support frame 201 and the guide block 203, the outer side of the support frame 201 is surrounded by a clamping block 202, and the end of the support frame 201 away from the extension bearing 2 is slidably connected to the housing 3; Wherein: the housing 3 is semicircular, the housing 3 surrounds the outer side of the cutting blade 102, a slide groove 1 is opened on one side of the housing 3, and a slide groove 2 is opened on the other side of the housing 3 close to the support frame 201; A slide groove 1 is provided on one side of the housing 3. Figure 6 As shown; The housing 3 is semicircular in shape and surrounds the outer side of the cutting blade 102. The housing 3 can reduce the dust splashing generated by the cutting blade 102 when the cutting blade 102 cuts the wall, and the housing 3 can protect the cutting end of the cutting blade 102. The extension bearing 2, the support frame 201 and the extension bearing 2 are combined into a "Z" shape; The support frame 201 is slidably nested with the second slide groove of the housing 3, and the support frame 201 is nested and fixed with the two ends of the slide groove of the housing 3. The overall weight of the support frame 201 and the housing 3 is 300-400g less than the weight of the guide block 203; The support frame 201 is nested and fixed with the two ends of the slide groove of the housing 3. Figure 2 As shown; The support frame 201 is slidably nested with the second slide groove of the housing 3, so that the housing 3 can be adjusted at one end of the support frame 201, thereby facilitating the cutting blade 102 to cut in the opposite direction; The overall weight of the support frame 201 and the housing 3 is 5-10 kg less than the weight of the guide block 203. When the upper end of the housing 3 is not hit by a heavy object, the housing 3 and the support frame 201 are located at the upper end of the extension bearing 2. Figure 2 As shown; The card blocks 202 are all nested inside the second slide groove of the housing 3; By setting the block 202, the friction between the support frame 201 and the housing 3 can be increased; Among them: the overall weight of the support frame 201 and the housing 3 is 5-10kg less than the weight of the guide block 203, so the housing 3 and the support frame 201 are located at the upper end of the extended bearing 2, and the guide block 203 is located at the lower end of the extended bearing 2, so the weight difference between the guide block 203 and the support frame 201 is utilized, and at this time the support frame 201 is in a stationary state; By manually pushing the housing 3, the second slide groove of the housing 3 slides 180° at one end of the support frame 201, which is convenient for adjusting the direction of the housing 3. Therefore, the housing 3 can be adjusted according to the cutting direction required by the cutting blade 102. The housing 3 is semicircular and surrounds the outer side of the cutting blade 102. When the cutting blade 102 cuts the wall, the dust splashing generated by the cutting blade 102 can be reduced. The cutting end of the cutting blade 102 can be protected by the housing 3. Example 3: Refer to the attached manual Figure 5-8 It can be seen that the difference between Example 3 and Example 1-2 is that the outer side of the housing 3 is slidably connected with a protective ring 4, and the side of the protective ring 4 close to the sliding groove 1 of the housing 3 is provided with a sliding ring 401, and the inner side of the sliding ring 401 is inlaid with a pad 402; Wherein: the protective ring 4, the sliding ring 401 is slidably nested and connected inside the slide groove 1 of the housing 3, the length of the sliding ring 401 is one third of the length of the slide groove 1, and the protective ring 4 is slidably connected to the housing 3 through the sliding ring 401; The sliding ring 401, the sliding ring 401 and the sliding groove of the housing 3 are both arranged in an arc shape, a groove is provided on the inner side of the sliding ring 401, and the cushion blocks 402 are respectively located on the inner sides of the grooves, and the ends of the cushion blocks 402 extend to one end of the sliding ring 401; A groove is provided on the inner side of the sliding ring 401, and the pads 402 are respectively located on the inner side of the groove, and the ends of the pads 402 extend to one end of the sliding ring 401. Therefore, when the sliding ring 401 is slidably nested with the inner side of the slide groove of the housing 3, the pads 402 can be attached to the inner wall of the slide groove of the housing 3. At this time, the pads 402 can assist the protective ring 4 and the housing 3 to be in a clamping state. The pads 402 are evenly arranged on the inner side of the sliding ring 401. There are 5 to 10 pads 402. The pads 402 are made of a deformable material, such as rubber. When the cushion block 402 is not deformed, the cushion block 402 is as shown in the attached manual. Figure 7 As shown; Among them: As the demolition device cuts and demolishes the wall, when concrete falls to the upper end of the cutting blade 102 during the cutting process, the concrete first hits the upper end of the protective ring 4, and the pad 402 inside the protective ring 4 is impacted, and the pad 402 is deformed toward the inner side of the groove of the sliding ring 401. Please refer to the attached manual for details. Figure 8 As shown; Since the sliding ring 401 is clamped with the housing 3 through the pad 402, when the pad 402 is deformed, the sliding ring 401 and the protective ring 4 can slide on the outside of the housing 3 as a whole. Since there are 5 to 10 pads 402, after multiple collisions, the pads 402 are gradually embedded in the grooves of the sliding ring 401, and the protective ring 4 can protect the housing 3 and the cutting blade 102. The housing 3 swings downward synchronously due to the impact, and the housing 3 and the protective ring 4 are both in an arc shape. The housing 3 can swing in an arc shape with the extended bearing 2 as the center point through the support frame 201. When the housing 3 swings, the guide block 203 is driven to swing upward through the extended bearing 2. By utilizing the weight difference of the guide block 203, after the guide block 203 swings upward, the guide block 203 can return to its original position through the extended bearing 2, and the housing 3 can return to its original position after being impacted, so that the housing 3 can prevent dust from splashing during the cutting process while protecting the cutting blade 102; Example

[0028] The process includes the following steps: S1: The hydraulic push rod 101 drives the bracket to adjust its height in the vertical direction, and then the motor 103 drives the cutting blade 102 to rotate 360 ​​degrees, so that the cutting blade 102 can cut and remove the building wall; S2: By manually pushing the housing 3, the second slide groove of the housing 3 slides 180° at one end of the support frame 201, so that the direction of the housing 3 can be adjusted conveniently, so that the housing 3 can be adjusted according to the cutting direction required by the cutting blade 102; S3: The demolition device cuts and demolishes the wall. During the cutting process, when concrete falls to the upper end of the cutting blade 102, the concrete first hits the upper end of the protective ring 4, and the pad 402 inside the protective ring 4 is impacted, and the pad 402 is deformed toward the inner side of the groove of the sliding ring 401; S4: The sliding ring 401 is connected to the housing 3 through the cushion block 402. When the cushion block 402 is deformed, the sliding ring 401 and the protective ring 4 can slide on the outside of the housing 3 as a whole. S5: Since there are 5 to 10 cushion blocks 402, after multiple collisions, the cushion blocks 402 are gradually embedded in the grooves of the sliding ring 401; S6: The housing 3 swings downward synchronously due to the impact, and the housing 3 and the protective ring 4 are both in an arc shape. The housing 3 can swing in an arc shape with the extended bearing 2 as the center point through the support frame 201. When the housing 3 swings, the guide block 203 is driven to swing upward through the extended bearing 2; S7: By utilizing the weight difference of the guide block 203, after the guide block 203 swings upward, the guide block 203 can return to its original position by extending the bearing 2, and the housing 3 can return to its original position after being impacted; Through the above steps, the cutting blade 102 can be protected by the outer shell 3 and the protective ring 4 during the cutting process to prevent concrete fragments from falling onto the surface of the cutting blade 102 after cutting. The cutting blade 102 rotates at a high speed, causing concrete fragments to splash. At the same time, the outer shell 3 surrounds the outside of the cutting blade 102 to form a dustproof function for the cutting end of the cutting blade 102 to prevent dust from splashing during the cutting process.

[0029] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
