Description

Technical Field

[0001] The utility model relates to the technical field of wood formwork drilling, in particular to a drilling device for the tie rod holes of wood formwork. Background Art

[0002] 1.1 Irregular production of tie rod holes:

[0003] In traditional construction of making tie rod holes in wood formwork, most operations are carried out by workers on the construction site, and they drill randomly with an electric drill. Due to the influence of subjective factors such as drilling equipment, angle, and strength, the diameter, shape, and position of the drilled holes are not standard, not regular, and not unified, which easily causes the formwork around the screw holes to split, resulting in inaccurate forming dimensions of concrete components, poor visual quality, and even formwork bulging or leakage.

[0004] 1.2 High-altitude operation is required for drilling beam formwork:

[0005] When using the traditional method for drilling, high-altitude operation is required, which poses potential safety hazards. Moving the movable frame increases labor intensity and has low construction efficiency. Using a quick drilling device for tie bolts can quickly and safely drill bolt holes with uniform diameter and shape, thus ensuring the geometric dimensions of concrete beam components.

[0006] 1.3 Low drilling efficiency

[0007] When using the traditional method for drilling, it is generally necessary to work inside a full hall scaffold. Since the vertical and horizontal poles of the scaffold have been set up, the movement of tools and equipment and the work efficiency of people will be affected accordingly, resulting in low drilling work efficiency.

[0035] As Figures 1-4 shown, this utility model provides a punching device for the tie rod holes of a wooden formwork, which includes a mounting assembly 100 and a locking assembly 200.

[0036] The mounting assembly 100 includes a main body frame 110, a sliding frame 120 and a mounting shell 130 which are oppositely arranged on the main body frame 110. The sliding frame 120 slides on the main body frame 110 and can approach or move away from the mounting shell 130 mounted on the main body frame 110. Among them, one end of the sliding frame 120 has a lifting rod 121 passing through the main body frame 110 and the mounting shell 130, and the lifting rod 121 can move up and down through the main body frame 110 and the mounting shell 130.

[0037] The locking assembly 200 includes a positioning button 210 and a locking rod 220. The positioning button 210 passes through the mounting shell 130 to realize the telescopic operation of the positioning button 210 on the mounting shell 130. A fixing plate 131 is connected to the mounting shell 130 near the lifting rod 121, so that there is a certain distance between the lifting rod 121 and the fixing plate 131, which can avoid affecting the up and down movement of the lifting rod 121 while serving as a platform for the locking rod 220 to rotate for positioning the lifting rod 121. The fixing plate 131 is connected to the positioning button 210 through an elastic member 211. The locking rod 220 is hinged to the fixing plate 131 at a position tending to the middle, and this hinge is connected and rotated through a shaft. Moreover, one end of the locking rod 220 abuts against the positioning button 210, and the other end can be clamped to the lifting rod 121. Among them, the elastic member 211 is a helical spring structure, and can control the locking rod 220 to position the lifting rod 121 through its own restoring force.

[0038] Based on the above technical solutions, when this utility model is specifically set up, it should be noted that.

[0039] As Figures 1-4As shown, the lifting rod 121 is a threaded structure. One end of the locking rod 220 close to the lifting rod 121 has a clamping member 221. The clamping member 221 can be clamped to the lifting rod 121. The clamping member 221 is a semi-circular structure, which just falls down and cooperates with the thread of the lifting rod 121 to clamp the lifting rod 121 tightly, so that it can no longer move up and down, realizing the fixation of the electric drill for drilling. The sliding frame 120 is slidably connected to the main frame 110. The sliding frame 120 and the bottom rod 111 of the main frame 110 can form a positioning cavity 122, which is used to place the electric drill for drilling, so as to realize the fixation of the electric drill for drilling operations. The sliding frame 120 is provided with binding strips 123 oppositely. Through the arrangement of the binding strips 123, the left and right directions of the electric drill can be fixed. At the same time, in cooperation with the sliding frame 120, the electric drill can be prevented from shaking in the up, down, left and right directions. One end of the positioning button 210 connected to the elastic member 211 has a limiting block 212. The diameter of the limiting block 212 is larger than that of the positioning button 210, and the inner side of the limiting block 212 abuts against the locking rod 220. This structure can not only push the lower end of the locking rod 220 to move inwards, but also prevent the lower end of the locking rod 220 from falling off the limiting block 212. The main frame 110 is provided with scale lines 112, and the height of the opening can be accurately and standardly controlled by opening holes according to the positions and sizes required in the plan and the operation instruction manual, so as to realize the opening of the beam formwork with a height of 0.1m - 1.5m. The control button can fix the lifting rod up and down.

[0040] The specific working principle and usage method of the present utility model are as follows: After the formwork is installed, the quick punching device is used for opening holes. The quick punching device is slidably connected with a sliding frame 120 on the main frame 110. The positioning cavity 122 formed by the sliding frame 120 and the bottom rod 111 of the main frame 110 can fix the tool for opening holes. The punching tool is adjusted by sliding the sliding frame 120 on the main frame 110. A locking assembly 200 is arranged on the sliding frame 120, through which positioning can be carried out to realize stable punching operations. There are corresponding scale lines 112 on the main frame 110, and the height of the opening can be accurately and standardly controlled by opening holes according to the positions and sizes required in the plan and the operation instruction manual, so as to realize the opening of the beam formwork with a height of 0.1m - 1.5m. The positioning button 210 can fix the lifting rod 121 up and down, and the height position of the punching device is controlled by the positioning button 210.

[0041] When the positioning button 210 is pressed inward, its limiting block 212 compresses the elastic member 211 towards the fixing plate 131. Then, the limiting block 212 simultaneously drives the lower end of the locking rod 220 to move inward, causing the locking rod 220 to rotate slightly on the fixing plate 131. As a result, the upper end of the locking rod 220 moves away from the lifting rod 121, and the clamping member 221 no longer clamps the lifting rod 121. At this time, the lifting rod 121 can be controlled to move up and down. When the positioning button 210 is released, under the action of the elastic member 211, the positioning button 210 will be pushed outward. Then, the clamping member 221 on the locking rod 220 returns to its original position, realizing the function of clamping the lifting rod 121 again.

[0042] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Any person skilled in the art of this industry can smoothly implement the present invention according to the illustrations in the specification and the above description. However, any equivalent changes, such as minor modifications, decorations, and evolutions made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above, are equivalent embodiments of the present invention. At the same time, any equivalent changes, such as modifications, decorations, and evolutions made to the above embodiments based on the essential technology of the present invention, still fall within the protection scope of the technical solution of the present invention.
