Description

Technical Field

[0001] The invention relates to the technical field of building construction devices, and in particular to a thermal insulation layer removing device for building construction. Background Art

[0002] When the developer delivers the house, the balcony is not considered as indoor area. The wall treatment of the balcony is consistent with the exterior wall treatment. The insulation layer is made to meet the delivery requirements, making the house unified and beautiful. After receiving the house, the owner will close the balcony and decorate the wall. This insulation layer is hollow. If you directly lay tiles and other decoration projects, the tiles will generally fall off in about three months. Therefore, the insulation layer on the balcony is usually removed before decoration to avoid unnecessary troubles such as tile falling off in the future. At present, the decoration master usually uses a handheld cutting machine to cut and divide the wall insulation layer, and then chisels off the insulation layer with a hammer. The removal is uneven, or the insulation layer is shoveled with a shovel at the weak bonding part, which is time-consuming and laborious.

[0003] How to solve the above technical problems is the subject faced by the present invention. Summary of the invention

[0006] When in use, firstly, the insulation layer on the wall is cut vertically and horizontally, and the two rejection components are controlled to rotate by the twisting component so that the saw faces of the two circular saws are parallel to each other. When the rotating shaft of the circular saw is vertical, the saw face of the circular saw is horizontal. The circular saw is turned on so that the two circular saws cut the wall insulation layer at the same time and control the cutting depth. The mechanism box is controlled to move in the horizontal direction by the mobile drive unit, and then the circular saw is withdrawn from the wall insulation layer. The mechanism box is controlled to move in the vertical direction to the next cutting position, and then the mechanism box is controlled to return in the horizontal direction. This cycle is repeated until the horizontal segmentation of the wall insulation layer is completed. The first motor drives the rotating rod to drive the mechanism box to rotate 90 degrees, so that the rotating shafts of the two circular saws are horizontal, that is, the saw faces of the circular saws are vertical, and the wall insulation layer is vertically segmented.

Taking the alignment of the circular saw with the vertical cutting seam as an example, the circular saw is turned on, and the mechanism box is controlled to move horizontally by the mobile drive unit at the same time, so that the circular saw aligned with the cutting seam cuts into the insulation layer and peels the insulation layer off the wall, and with the movement of the mechanism box, the other circular saw cuts the peeled insulation layer into small pieces and drops them, so as to prevent the peeled insulation layer from interfering with the removal operation, and with the further movement of the mechanism box, a horizontal section of the insulation layer after segmentation can be evenly removed, and the mechanism box is controlled to move vertically to the next horizontal section of the insulation layer, and the removal operation can be repeated, saving time and effort.

At the same time, during the stripping and removing operation, the cutting end of the circular saw aligned with the cutting seam can be extended longer, making it easier to achieve the stripping and cutting coordination operation of the two circular saws, thereby improving the working efficiency.

There is also a handrail arranged on the end of the bottom box near the control box, which is convenient for the operator to hold when cutting or peeling.

[0020] A method for removing a thermal insulation layer using the thermal insulation layer removing device for building construction comprises the following steps:

[0021] Step S1: cutting the insulation layer on the wall in the vertical and horizontal directions: controlling the rotation of the two rejection components by the twisting component so that the saw faces of the two circular saws are parallel to each other and are horizontal / vertical, turning on the circular saws so that the two circular saws cut the wall insulation layer at the same time and controlling the cutting depth, controlling the mechanism box to move in the horizontal / vertical direction by the mobile drive unit, then withdrawing the circular saw from the wall insulation layer, controlling the mechanism box to move in the vertical / horizontal direction to the next cutting position, and then controlling the mechanism box to return in the horizontal / vertical direction, and repeating this cycle until the horizontal / vertical segmentation of the wall insulation layer is completed, and driving the mechanism box to rotate 90° by the first motor to drive the rotating rod to perform the vertical / horizontal segmentation of the wall insulation layer;

[0022] Step S2: Peeling and removing the divided wall insulation layer: control the rotation of the two removal components through the torsion component, so that the cutting ends of the two circular saws are close to each other, and the cutting end of one of the circular saws is aligned with any longitudinal / transverse cutting seam, turn on the circular saw, and at the same time control the mechanism box to move in the horizontal / vertical direction through the mobile drive unit, so that the circular saw aligned with the cutting seam cuts into the insulation layer and peels the insulation layer from the wall, and as the mechanism box moves, the other circular saw cuts the peeled insulation layer into small pieces and drops them, and as the mechanism box moves further, the divided horizontal / vertical insulation layer can be evenly removed, and the mechanism box is controlled to move in the vertical / horizontal direction to the next horizontal / vertical insulation layer, and the peeling and removal operation is repeated.

[0023] Step S1 also includes adjusting the distance that the cutting end of the circular saw extends out of the through slot before starting the circular saw. Specifically, the position of the first threaded rod in the arc slot is adjusted, and the first fastening sleeve is used to tighten and limit the position. The support plate is flipped along the first hinge part, driving the second motor to flip with the support plate, thereby adjusting the distance that the cutting end of the circular saw extends out of the through slot.

[0024] The method for controlling the cutting depth in step S1 includes holding the handrail and pushing the base toward or away from the wall.

[0025] Step S2 also includes adjusting the distances by which the cutting ends of the two circular saws extend out of the through slot before turning on the circular saw, so that the distance by which the cutting end of the circular saw aligned with the cutting slot extends out of the through slot is greater than the distance by which the cutting end of the other circular saw extends out of the through slot. When the cutting end of the circular saw aligned with the cutting slot extends into the cutting slot, the other circular saw rests against the surface of the insulation layer or slightly extends into the insulation layer. When the mechanism box moves, as one circular saw cuts into the insulation layer, the peeled-off insulation layer bends, and the other circular saw cuts the bent insulation layer into small pieces.

[0026] The method of controlling the rotation of the two rejecting components by the torsion component in step S1 and step S2 includes: sliding the first slider along the slide rod, the telescopic tube slides with the first slider, driving the two telescopic rods to move synchronously and extend or retract simultaneously, so that the two rejecting components rotate along the hinged part to achieve torsion; at this time, the position of the second threaded rod in the third slide groove changes synchronously, and the first slider can be moved by tightening and limiting by the second fastening sleeve, thereby achieving torsion and limiting of the rejecting component.

[0027] The method for removing the thermal insulation layer also includes step S3: adjusting the height by using the lifting platform according to the height of the wall, and repeating steps S1 and S2.

[0028] The beneficial effects of the present invention are as follows: the torsion component provided in the present invention can realize the switching of the saw faces of the two circular saws between parallel and non-parallel states; when the saw faces are parallel, the mobile drive unit cooperates with the first motor to perform vertical and horizontal cutting of the wall insulation layer; when the saw faces are non-parallel, the cut insulation layer is peeled off and removed, with high removal efficiency and good removal effect, saving time and effort, and easy operation; the present invention has a simple structure, can perform insulation layer removal operations on walls of different heights, and has strong applicability.

[0053] Step S2: Peeling and removing the divided wall insulation layer: Control the rotation of the two removal components 21 through the torsion component, so that the cutting ends of the two circular saws 211 are close to each other, and the cutting end of one of the circular saws 211 is aligned with any longitudinal / transverse cutting seam, turn on the circular saw 211, and control the mechanism box 22 to move in the horizontal / vertical direction through the mobile drive unit 3, so that the circular saw 211 aligned with the cutting seam cuts into the insulation layer and peels the insulation layer from the wall, and as the mechanism box 22 moves, the other circular saw 211 cuts the peeled insulation layer into small pieces and drops them, and as the mechanism box 22 moves further, a horizontal section / vertical section of the insulation layer after segmentation can be evenly removed, and the mechanism box 22 is controlled to move in the vertical / horizontal direction to the next horizontal section / vertical section of the insulation layer, and the peeling and removing operation is repeated.

[0054] Step S1 also includes adjusting the distance that the cutting end of the circular saw 211 extends out of the through slot 221 before starting the circular saw 211. Specifically, the position of the first threaded rod 214 in the arc slot 2124 is adjusted, and the first fastening sleeve 215 is used to tighten and limit the position. The support plate 213 is flipped along the first hinge part 2122, driving the second motor 210 to flip along with the support plate 213, thereby adjusting the distance that the cutting end of the circular saw 211 extends out of the through slot 221.

[0055] The method for controlling the cutting depth in step S1 includes holding the handrail 15 and pushing the base 1 toward or away from the wall.

[0056] Step S2 also includes adjusting the distances by which the cutting ends of the two circular saws 211 extend out of the through slot 221 before turning on the circular saw 211, so that the distance by which the cutting end of the circular saw 211 aligned with the cutting seam extends out of the through slot 221 is greater than the distance by which the cutting end of the other circular saw 211 extends out of the through slot 221. When the cutting end of the circular saw 211 aligned with the cutting seam extends into the cutting seam, the other circular saw 211 rests against the surface of the insulation layer or slightly extends into the insulation layer. When the mechanism box 2 moves, as one circular saw 211 cuts into the insulation layer, the peeled-off insulation layer bends, and the other circular saw 211 cuts the bent insulation layer into small pieces.

[0057] The method for controlling the rotation of the two rejecting components 21 by the torsion component in step S1 and step S2 includes: sliding the first slider 24 along the slide rod 23, and the telescopic cylinder 25 slides with the first slider 24, driving the two telescopic rods 26 to move synchronously and extend or retract simultaneously, so that the two rejecting components 21 rotate along the hinged part to achieve torsion; at this time, the position of the second threaded rod 27 in the third slide groove 222 changes synchronously, and the first slider 24 can be moved by tightening and limiting by the second fastening sleeve 28, thereby achieving torsion and limiting of the rejecting component 21.

[0058] The method for removing the thermal insulation layer further includes step S3: adjusting the height by means of the lifting platform 11 according to the height of the wall, and repeating steps S1 and S2.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
