Description

Technical Field

[0001] The invention relates to the technical field of indoor concrete floor finishing devices, in particular to a horizontal concrete removal mechanism used for finishing the concrete floor of an indoor space of a building. Background Art

[0002] The indoor floors of modern high-rise buildings are generally made of concrete poured horizontally as a whole. However, in the subsequent construction process, such as wall construction and wall surface leveling, the concrete used in the construction process will remain on the ground and form hard concrete blocks, making the ground uneven. The solution of the existing technology is to hire people to use electric picks and pneumatic picks to remove the raised concrete blocks on the ground one by one. The single operation area of ​​pneumatic picks or electric picks is small, the construction efficiency is low, and it is difficult to completely remove them, which delays the acceptance time and affects the acceptance results.

[0003] At the same time, in construction scenarios such as demolishing old floors, pneumatic picks or electric picks have the following insurmountable defects: 1. When working, pneumatic picks or electric picks continuously hit and break the floor through the pick head. The direct impact of the pick head and the floor slab produces huge noise pollution and spreads through the building structure, which is not conducive to the health of personnel and disturbs the residents and easily causes neighborhood disputes; 2. Through long-term on-site construction observations, it is found that when workers use pneumatic picks or electric picks, in order to save effort and quickly break the floor, they will occasionally use the pneumatic picks or electric picks to construct in the direction perpendicular to the floor slab surface, which is easy to damage the original underground power supply, water supply and heating pipelines, causing short circuits in the wires to affect electricity safety or form leaks to damage the decoration downstairs; at the same time, because the thickness of the floor slab is generally only 80mm-120mm, this non-standard construction method is very easy to cause subtle hidden injuries and hidden dangers to the floor slab structure, especially in the construction of old prefabricated board buildings, because the prefabricated board structure is hollow and has poor strength and is more easily damaged; However, during the on-site construction process, the sources of workers and construction sites are scattered, and it is extremely difficult to achieve unified and standardized management. Therefore, this non-standard construction phenomenon is widespread and difficult to prohibit.

[0004] Therefore, a horizontal concrete removal mechanism is urgently needed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

However, this should not be understood as the scope of the above subject matter of the present invention being limited to the following examples. Various substitutions or changes made according to common technical knowledge and customary means in the art without departing from the above technical ideas of the present invention should be included in the scope of the present invention.

[0028] Embodiment 1:

[0029] A horizontal concrete removal mechanism of this embodiment includes a support guide mechanism 1 and a device body 2;

[0030] The support guide mechanism 1 comprises a bottom plate 11, a support height adjustment mechanism 12, a horizontal guide rail 13, a top telescopic support mechanism 14 and a top plate 15; the bottom end of the support height adjustment mechanism 12 is fixedly mounted on the bottom plate 11, the top of the support height adjustment mechanism 12 carries the horizontal guide rail 13 and the top telescopic support mechanism 14, the bottom end of the top telescopic support mechanism 14 is fixedly mounted on the top of the support height adjustment mechanism 12, and the top of the top telescopic support mechanism 14 is provided with a top plate 15;

[0031] The device body 2 is located on one side of the ground area to be trimmed, and includes a mounting frame 21, a motor 22, a transmission mechanism and a crushing mechanism; the device body 2 is slidably mounted on the horizontal guide rail 13 through a mounting mechanism 211 provided on the mounting frame 21, and the motor 22 is fixedly mounted on the mounting frame 21, and the motor is driven by the transmission mechanism to rotate the crushing mechanism; the transmission mechanism includes an elastic coupling 231, a first transmission shaft 232, a second transmission shaft 233, a first sprocket 234, a second sprocket 235 and a chain 236, and the main shaft output end of the motor 22 is connected to the horizontal guide rail 13 through an elastic coupling. 231 is connected to the first transmission shaft 232, the first transmission shaft 232 and the second transmission shaft 233 are fixedly mounted on the mounting frame 21 through the inner ring of the bearing, the first transmission shaft 232 is mounted with a first sprocket 234, the second transmission shaft 233 is mounted with a second sprocket 235, the first sprocket 234 and the second sprocket 235 are driven by a chain 236; rectangular mounting sections 241 extend from both ends of the second transmission shaft 233, a crushing wheel 242 is detachably mounted on the rectangular mounting section 241, and crushing teeth 2421 made of cemented carbide are provided on the outer periphery of the crushing wheel 242.

[0032] In this embodiment, the device body 2 is installed on the support and guide mechanism 1, and the support and guide mechanism 1 plays the role of bearing and guiding the device body 2. The bottom plate 11 in the support and guide mechanism 1 is fixedly installed at the bottom end of the support height adjustment mechanism 12. The top of the support height adjustment mechanism 12 is detachably installed with a horizontal guide rail 13, and the device body 2 is slidably installed on the horizontal guide rail 13, so that the device body 2 can slide along the horizontal guide rail 13. When in use, the horizontal guide rail 13 is adjusted to a suitable height by the support height adjustment mechanism 12, so that the floor structure will not be damaged due to excessive cutting of the crushing wheel 242 during ground finishing construction of the device body 2, especially when dismantling the old floor, so that the cutting depth of the crushing wheel 242 remains constant, effectively avoiding damage to the embedded pipelines; the top telescopic support mechanism 14 and the top plate 15 installed on the top of the support height adjustment mechanism 12, by extending the top telescopic support mechanism 14, the top plate 15 is pressed against the ceiling, so as to avoid the force affecting the balance of the device body 2 when the device body 2 is working.

[0033] An elastic coupling 231 is used in the transmission mechanism of the device body 2 to connect the main shaft output end of the motor 22 and the first transmission shaft 232 to prevent the motor 22 from being stuck when the crushing wheel 242 is subjected to excessive force and cannot rotate in time during startup, and effectively prevent the main shaft from being stuck when the motor 22 is started and causing the coil to burn. Because the crushing wheel 242 may be subjected to a large reaction force when working, a chain transmission method of the first sprocket 234, the chain 236, and the second sprocket 235 is adopted, which can withstand a large reaction force and avoid failure of the belt transmission.

[0034] Rectangular mounting sections 241 are provided at both ends of the second transmission shaft 233, and a plurality of crushing wheels 242 are fixedly mounted on the rectangular mounting sections 241. The number, diameter and wheel width of the crushing wheels 242 can be used to adjust the working area and cutting depth. By installing a single or multiple crushing wheels 242 at intervals, the ground can be grooved to facilitate wiring and pipe burial. Crushing teeth 2421 made of cemented carbide are installed on the outer periphery of the crushing wheel 242, which has good wear resistance and is beneficial to extending the service life of the crushing wheel 242.

[0035] In this embodiment, the crushing teeth 2421 on the crushing wheel 242 are arc-shaped teeth. When working, the tooth head moves from bottom to obliquely upward at a linear speed, and hits the protruding concrete block or floor tile side to be trimmed, and crushes the concrete block or floor tile obliquely upward, avoiding the impact from top to bottom that causes a large force on the floor, effectively reducing the vibration of the building and the spread of noise, and preventing the building from being damaged by vibration.

[0036] Embodiment 2:

[0037] This embodiment is further optimized on the basis of embodiment 1. Figure 2 As shown, the number of crushing wheels 242 on the rectangular mounting section 241 is one or more.

[0038] The processing area of ​​the device can be adjusted by changing the number of crushing wheels 242 installed on the rectangular mounting section 241.

[0039] A first protective shell 001 is disposed outside the first sprocket 234 , the second sprocket 235 and the chain 236 . The first protective shell 001 is connected to the first transmission shaft 232 and the second transmission shaft 233 respectively through the outer ring of the bearing. The first protective shell 001 is fixedly connected to the mounting frame 21 .

[0040] The first protective shell 001 forms a relatively closed space to protect the first sprocket 234, the second sprocket 235 and the chain 236, so as to prevent debris from flying and getting stuck between the sprocket and the chain 236 during construction and causing damage.

[0041] The bottom surface of the bottom plate 11 and the top surface of the top plate 15 are both provided with shock absorbing pads.

[0042] The shapes of the bottom plate 11 and the top plate 15 can be various shapes such as triangle, circle, rectangle, etc. The shock-absorbing pad is attached to the bottom plate 11 or the top plate 15 to form a buffer layer between the bottom plate 11 and the ground, and between the top plate 15 and the ceiling, so as to reduce the direct impact of mechanical vibration on the building.

[0043] A second protective shell 003 is provided on the outer side of the crushing wheel 242 , and the second protective shell 003 is fixedly connected to the mounting frame 21 .

[0044] A dust suction pipe 0031 is provided through the second protective shell 003 , the air inlet of the dust suction pipe 0031 is located on the inner side of the second protective shell 003 , the air inlet of the dust suction pipe 0031 is provided with a grate plate 0032 , and the air outlet end of the dust suction pipe 0031 is connected to a dust suction device 0033 .

[0045] The dust generated during construction is collected in time through the dust suction device 0033 and the dust suction pipe to prevent the dust from being dispersed in the air and inhaled by the construction workers, thereby effectively protecting the health of the construction workers. At the same time, a grate plate 0032 is installed at the air inlet to prevent fragments with too large diameter from entering the dust suction device 0033 and causing damage.

[0046] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form.
