Description

Technical Field

[0001] The present invention relates to the technical field of concrete drilling, and particularly to a drilling device for building construction. Background Art

[0002] During the building construction process, drilling operations need to be performed on some walls. For example, for pipeline layout and subsequent installation of air conditioners, drilling operations need to be carried out on concrete walls. Among them, for different diameters of holes to be drilled, different drilling equipment is used. For holes with a relatively small drilling diameter, the drill bit can be directly driven by an electric drill for drilling. However, for large-diameter holes, a drill barrel needs to be used for drilling.

[0003] When drilling a concrete wall, the drill barrel used penetrates into the concrete wall. During this process, the most unstable situation is when aligning the position to be drilled. The drill barrel is likely to deviate from the drilling position due to the torque of the electric drill when it contacts the concrete wall. The torque of the electric drill will also drive the worker to deviate. If standing on a ladder, it is particularly easy to fall. In addition, the force of the worker's body is concentrated on the electric drill. Therefore, when the hole is suddenly opened and the supporting force is lost, it is easy to cause the worker to lose balance and fall, and thus there is a relatively large potential safety hazard, so improvement is needed.

[0040] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manner of the present invention with reference to the drawings of the specification.

[0041] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0042] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0043] Embodiment 1, refer to Figures 1 - 6 , which is the first embodiment of the present invention. This embodiment provides a drilling device for building construction, which can achieve the effect of not easily deviating the drilling position. It includes a main body component 100, which includes a housing component 101 and a support component 102 fixed to the end of the housing component 101. It also includes a drilling component 103 that slides within the housing component 101. By squeezing the housing component 101, the support component 102 is driven to fit against the wall surface, and by pushing the drilling component 103, the drilling area can be processed;

[0044] A prompting component 200, which includes an orbital component 201 that rotates on the top of the housing component 101. The orbital component 201 is connected to the drilling component 103, and a display component 202 fixed to the end of the orbital component 201. When the drilling component 103 moves, it can drive the orbital component 201 to rotate, and the orbital component 201 can trigger the display component 202 to display the drilling depth;

[0045] Limited component 300, which includes a limit component 301 fixed to the end face of the display component 202, further includes an adjustment component 302 fixed to the end face of the limit component 301, and further includes an elastic component 303 sliding on the adjustment component 302. The elastic component 303 is connected to the housing component 101. The limit component 301 can limit the rotation distance of the display component 202, and the adjustment component 302 and the elastic component 303 cooperate to adjust the limit distance of the limit component 301 to the display component 202.

[0046] Specifically, as Figure 5 shown in [reference], the housing component 101 includes a housing 101a, with a first reserved groove 101b and a second reserved groove 101c provided on both sides of the housing 101a respectively, a sliding groove 101d provided on the top of the housing 101a, and a cover plate 101e fixed to the end of the housing 101a. It further includes a soft pad 101f fixed to the end face of the cover plate 101e. The surface of the soft pad 101f has a curvature, and the curvature on the soft pad 101f is adapted to the shoulder to lean against. It further includes a handle 101g fixed to the bottom of the housing 101a, and the handle 101g is for right - hand holding.

[0047] Furthermore, as Figure 4 shown in [reference], the support component 102 includes a ring 102a fixed to the end of the housing 101a, and a friction pad 102b fixed in the end - face groove of the ring 102a. The friction pad 102b is fan - shaped, and there are six friction pads 102b. The six friction pads 102b are arranged in a ring on the end face of the ring 102a.

[0048] Furthermore, as Figure 6 shown in [reference], the punching component 103 includes a device shell 103a sliding on the inner wall of the housing 101a, and a motor 103b fixed to the inner wall of the device shell 103a. It further includes a water - injection connecting rod 103c fixed to the driving end of the motor 103b. The water - injection connecting rod 103c is provided with a water - injection end 103d at the first reserved groove 101b, and a driving rod 103e at the second reserved groove 101c. It further includes a punching part 103f fixed to the end of the water - injection connecting rod 103c. The water - injection connecting rod 103c can inject water through the water - injection end 103d and discharge it from the grinding end of the punching part 103f.

[0049] In use, the main body component 100 is lifted to the shoulder by holding the handle 101g on the right side, and the shoulder is abutted against the soft pad 101f. At this time, the support component 102 is aligned with the drilling position. The shoulder abuts against the soft pad 101f, the cover plate 101e, and the outer shell 101a, so that the outer shell 101a transmits the force to the ring 102a and the friction pad 102b. The friction pad 102b contacts the wall, thereby providing a stable support before grinding. At this time, by starting the motor 103b, the driving end of the motor 103b drives the water injection connecting rod 103c to drive the drilling member 103f to rotate through the water injection connecting rod 103c, and at the same time, the water injection end 103d is opened to introduce water into the drilling member 103f. At this time, by slowly pushing the driving rod 103e to drive the water injection connecting rod 103c, the motor 103b, the equipment shell 103a, and the drilling member 103f to approach the wall until the drilling is completed. During this process, the equipment shell 103a slides on the inner wall of the outer shell 101a. The torque during the drilling process will be transmitted to the outer shell 101a, the cover plate 101e, the soft pad 101f, the shoulder, the ring 102a, and the friction pad 102b through the drilling component 103. Therefore, the abutting force of the shoulder and the friction force between the friction pad 102b and the wall can make the drilling process more stable, so that the drilling component 103 is not easily offset from the drilling position.

[0050] In summary, through the cooperation of the worker using the housing component 101 and the support component 102, the drilling component 103 is not easily offset from the drilling position during drilling, and the track component 201 and the display component 202 are triggered by the drilling component 103, so that the worker can observe the display component 202 to know the drilling depth during drilling, avoiding the problem of suddenly losing support and falling after the hole is drilled through, thereby improving the practicability and safety performance during the drilling process.

[0051] Embodiment 2, referring to Figures 1 - 8 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a prompt component 200 for the drilling device used in building construction, which has the function of viewing the drilling depth of the drilling component 103. As Figure 7 shown, it includes that the track component 201 includes a guide roller 201a rotating on the top of the housing component 101. The guide roller 201a rotates at the corresponding chute 101d on the top of the outer shell 101a in the housing component 101. The outer wall of the guide roller 201a is provided with a spiral groove 201b. The spiral range of the spiral groove 201b is one circle, and there are two spiral grooves 201b. The two spiral grooves 201b are relatively located on the outer wall of the guide roller 201a, and a connecting seat 201c moving on the outer wall of the guide roller 201a. The connecting seat 201c can slide inside the chute 101d, and the connecting seat 201c is connected to the drilling component 103. The connecting seat 201c is connected to the equipment shell 103a in the drilling component 103. It also includes sliders 201d fixed on both sides of the end of the connecting seat 201c. The sliders 201d are adapted to the spiral groove 201b.

[0052] Specifically, as shown in Figure 8 Figure [0000127], the display component 202 includes a turntable 202a fixed to the end of the guide roller 201a. A display groove 202b is provided at one end of the turntable 202a located on the guide roller 201a. The maximum distance that the connecting seat 201c can move on the guide roller 201a is marked on the display groove 202b, and a pointer 202c adapted to the display groove 202b. The position where the pointer 202c points to the display groove 202b is the distance that the connecting seat 201c moves on the guide roller 201a. Since the connecting seat 201c is connected to the punching component 103, the distance that the connecting seat 201c moves on the guide roller 201a is the depth of the punched hole. The pointer 202c is connected to the housing component 101, and the pointer 202c is connected to the top of the outer shell 101a in the housing component 101.

[0053] The remaining structures are the same as those in Embodiment 1.

[0054] When in use, when punching through the punching component 103, the equipment shell 103a in the punching component 103 will move. When the equipment shell 103a moves, it will drive the connecting seat 201c and the slider 201d to move towards the other end of the guide roller 201a. During this process, the slider 201d moves in the spiral groove 201b on the outer wall of the guide roller 201a, so the guide roller 201a will rotate. When the guide roller 201a rotates, it will drive the turntable 202a to rotate. Thus, by checking the position on the display groove 202b on the turntable 202a pointed by the pointer, the depth of the hole punched by the punching component 103 can be known.

[0055] In summary, it enables workers to observe the display component 202 during punching to know the punching depth, avoiding the problem of suddenly losing support and falling after the hole is punched through, and improving the safety performance during the punching process.

[0056] Embodiment 3, referring to Figures 1 - 11 Figure [0000136], is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a limiting component 300 for the punching device used in building construction, which has the function of limiting the punching depth of the punching component 103. As shown in Figure 10 Figure [0000137], it includes that the limiting component 301 includes a dial 301a, and a resisting block 301b fixed to the end face of the dial 301a corresponding to one end of the display component 202. It also includes a first triangular block 301c fixed to the side end of the dial 301a corresponding to the resisting block 301b. It further includes a second triangular block 301d adapted to the first triangular block 301c. When the first triangular block 301c and the second triangular block 301d are in the initial state, the inclined surfaces of the two are in a fitting state. The second triangular block 301d is connected to the display component 202, and the second triangular block 301d is connected to the turntable 202a in the display component 202.

[0057] Specifically, as shown in Figure 11 , the adjusting component 302 includes a first ratchet wheel 302a fixed to one end of the dial 301a away from the abutting block 301b, and a round block 302b fixed to the end face of the first ratchet wheel 302a. It further includes a second ratchet wheel 302c movably disposed on the outer wall of the round block 302b, and a square block 302d fixed to the end face of the second ratchet wheel 302c.

[0058] Furthermore, as shown in Figure 11 , the elastic component 303 includes a fixed seat 303a fixed to the top of the housing component 101. The fixed seat 303a is fixed to the top of the outer shell 101a of the housing component 101. The fixed seat 303a is provided with a circular groove 303b at one end located at the adjusting component 302. The circular groove 303b is adapted to the first ratchet wheel 302a and the second ratchet wheel 302c. The fixed seat 303a is provided with a square groove 303c inside the circular groove 303b. The square groove 303c is adapted to the square block 302d. The square block 302d can slide in the square groove 303c, and a spring 303d fixed in the square groove 303c is also connected to the square block 302d.

[0059] The remaining structures are the same as those in Embodiment 2.

[0060] During use, when it is necessary to limit the drilling depth of the drilling component 103, by rotating the dial 301a, the inclined surface of the first triangular block 301c squeezes the inclined surface of the second triangular block 301d. Thus, the first triangular block 301c will drive the dial 301a, the first ratchet wheel 302a, the second ratchet wheel 302c, and the square block 302d, causing the square block 302d to squeeze the spring 303d. When the first triangular block 301c passes over the second triangular block 301d, the plane of the first triangular block 301c and the plane of the second triangular block 301d are opposite to each other and form a limit. At this time, the turntable 202a and the guide roller 201a cannot operate. Then, when the dial 301a is toggled again to make the plane of the first triangular block 301c away from the plane of the second triangular block 301d, there is still a rotational distance between the first triangular block 301c and the second triangular block 301d. At this time, the turntable 202a and the guide roller 201a can operate, but the operating range is the distance between the plane of the first triangular block 301c and the plane of the second triangular block 301d. Therefore, if more distance is required, the dial 301a can be continuously rotated. Each time the dial 301a makes the plane of the first triangular block 301c and the plane of the second triangular block 301d opposite to each other, it can rotate one circle to adjust the required drilling depth. During this process, each time the dial 301a is toggled, it will drive the first ratchet wheel 302a to lift the second ratchet wheel 302c, the square block 302d squeezes the spring 303d, and then the spring 303d squeezes the square block 302d, and the second ratchet wheel 302c engages with the first ratchet wheel 302a.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
