Description

Technical Field

[0001] The utility model belongs to the field of building construction, and in particular relates to a mobile circular saw with adjustable protection height. Background Art

[0002] Wooden formwork is widely used in the construction industry. According to the different cross-sectional dimensions of the main structural elements of the building design, wooden formwork is cut into different sizes, and the processing process usually takes place on the construction site. According to the principle of "every shaft must have a sleeve, every wheel must have a cover," circular saws are usually equipped with protective covers. However, conventional protective covers cannot be adjusted in height according to the thickness of the raw material, and they do not work when not in operation. Furthermore, operators need to use both hands to push the raw material to the circular saw blade, resulting in poor protective effects. Furthermore, a large amount of wood waste is generated during the circular saw cutting operation, which randomly falls onto the work surface and is not handled in a centralized and regular manner, making it prone to fire. Circular saw distribution boxes are usually insufficiently configured, and the distance between the distribution box and the circular saw is usually greater than 3 meters. Summary of the Invention

DETAILED DESCRIPTION

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example:

[0027] The support vertical pole 13 is welded with the rainproof baffle 11, the bottom plate 10, the hanging lug 12, and the support cross bar 14 to form a whole;

[0028] The fixing rod 5 is fixed to the top plate by welding;

[0029] The adjusting rod 2 is connected to the fixed rod 5 through the adjusting slot 4 and the adjusting nut 3, and the adjusting rod 2 can move up and down;

[0030] The protective cover 1 is connected to the adjustment rod 2 by welding;

[0031] The circular saw 6 is fixed on the base plate 10;

[0032] The insulating rubber pad 9 is placed on the bottom plate 10;

[0033] The sawdust collection box 8 is non-rigidly connected to the circular saw 6 and can be moved for cleaning;

[0034] The fire extinguisher 15 and the distribution box 16 are fixed on the support crossbar 14;

[0035] The reserved groove 17 is provided on the operating surface of the circular saw;

[0036] The L-shaped safety handle 18 is arranged on the reserved groove 17 and can move forward and backward along the reserved groove 17;

[0037] The fixed telescopic rod 20 is provided with two rigid connections with the L-shaped safety handle 18 , and the first reserved hole 19 is provided on the fixed telescopic rod 20 ;

[0038] The adjustable telescopic rod 21 can be adjusted in length through the first reserved hole 19 and the fixed telescopic rod 20;

[0039] The fixture base 22 is rigidly connected to the adjustable telescopic rod 21;

[0040] The height of the clamp 24 can be adjusted on the clamp base 22 through the second reserved hole 23;

[0041] Operation steps: When the work surface requires templates and wood processing, the circular saw is lifted to the work surface by a tower crane using the lifting lug 12. Since the circular saw has its own three-level distribution box, it only needs to lead the wires from the second-level distribution box to the third-level distribution box, meeting the regulatory requirements that the distance between the distribution box and the operating machine should not exceed 3 meters. During operation, move the adjustment rod 2 up and down to the appropriate position according to the thickness of the wood template and the thickness of the wood, and fix it by adjusting the nut 3. The circular saw protective cover completes the protection. According to the width of the wood template and the width of the wood, adjust the adjustable telescopic rod 21 through the first reserved hole 19 so that the clamp 24 can fully fit the wood and fix the wood. According to the thickness of the wood template and the thickness of the wood, adjust the height of the clamp 24 up and down through the second reserved hole 23 so that the clamp 24 can fully fit the wood and fix the wood. The operator holds the L-shaped safety handle 18 with both hands and pushes the wood toward the circular saw blade. The L-shaped safety handle 18 completes the forward and backward displacement through the reserved slot 17. By utilizing the L-shaped safety handle 18 , the operator does not need to push both hands close to the circular saw blade, thereby greatly improving safety.

[0042] When the circular saw is not in operation, the adjustment lever 2 can be moved to the lowest position. At this time, the circular saw blade is fully covered by the protective cover to avoid scratches to personnel.

[0043] The wood chips generated during the raw material processing slide into the wood chip collection box 8 through the inclined plate 7. The operator regularly cleans the wood chips in the wood chip collection box 8. A fire extinguisher 15 is provided on the support crossbar 14 to prevent the wood chips from accidentally catching fire.

[0044] A rainproof baffle 11 and a roof are provided to prevent objects from falling and injuring the operator and to prevent rainwater from dripping onto the circular saw. When it is necessary to transport the saw to other working surfaces, the saw is hoisted to other working surfaces by a tower crane.
