Description

Technical Field

[0001] This utility model relates to a drilling machine, specifically a drilling machine for building construction, and belongs to the field of construction machinery technology. Background Technology

[0002] Drilling machines are a general term for machines and equipment that use tools harder and sharper than the target object to leave cylindrical holes or openings in the target object through rotary cutting or rotary extrusion. They are also called drilling machines, hole punching machines, eye punching machines, through-hole machines, etc. Building construction refers to the production activities in the implementation phase of engineering construction. It is the process of building various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. In the process of building construction, drilling with a drilling machine is an essential operation.

[0003] However, when using existing small-scale construction drilling machines, workers manually hold or operate the machines. Due to varying drilling heights, workers need to frequently change their work positions. Because the work area is small, on the one hand, manually holding a drilling machine is inconvenient for drilling at higher positions, and on the other hand, manual drilling is subjective and prone to deviations in drilling angle, thus affecting the efficiency of construction work. On the other hand, automatic drilling equipment is larger and more difficult to operate and move. After each movement, it is necessary to repeatedly calibrate and reposition, and it may also cause damage to the construction site due to mechanical movement.

[0004] Therefore, although automatic drilling equipment can save workers' physical strength and simplify the operation, the limited space and scattered work points make it difficult to move the equipment, which in turn causes inconvenience to workers; while manual hand-held drilling is difficult to guarantee the efficiency and drilling accuracy of long-term operation.

[0005] Therefore, a drilling machine for building construction is proposed to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a drilling machine for building construction that is easy to install and adjust.

[0007] To achieve the above objectives, the present invention provides a drilling machine for building construction, comprising a drilling machine body and a base, wherein a drill bit is fixedly connected to the outside of the drilling machine body, and an installation and adjustment structure is provided between the drilling machine body and the base;

[0008] The installation and adjustment structure includes a folding component, a lifting component, and a feeding component. The lower end of the folding component is mounted on the base. The folding component is used to fold or unfold the drilling machine body.

[0009] The upper end of the folding assembly is sequentially connected to a lifting assembly and a feeding assembly. The lifting assembly is used to adjust the working height of the drilling machine body.

[0010] The feed assembly is slidably connected to the drilling machine body along the drilling direction; the feed assembly is used to drive the drill bit to adjust the drilling stroke.

[0011] The folding assembly includes a turntable, a first mounting block, a first folding motor, a support plate, a second mounting block, and a second folding motor. A turntable is provided below the lifting assembly, and first mounting blocks are symmetrically arranged on both sides of the turntable. A first folding motor is mounted on one side of the first mounting block. The first folding motor is used to drive the lifting assembly on the turntable to rotate.

[0012] The bottom end of the first mounting block is connected to multiple support plates. Each support plate has a second mounting block symmetrically arranged on both sides. The second mounting block is used to install a second folding motor, and the second folding motor is used to unfold the multiple support plates upward.

[0013] The lower support plate is mounted on the base via the second mounting block at the lower end.

[0014] The lifting assembly includes a support column, a threaded column, and a lifting motor. The support column is located below the feeding assembly. The threaded column is connected to the inside of the support column by a thread. The lifting motor is connected to the end of the threaded column and is mounted on the turntable.

[0015] A limit rod is vertically installed on the top surface of the turntable, and a limit block is installed on the lower side of the threaded column. The limit block is slidably sleeved on the limit rod.

[0016] Since the support column is slidably mounted on the threaded column, the rotation of the threaded column drives the support column to rise and fall, which in turn drives the feed assembly on the support column to rise and fall. However, relying solely on the positioning and sliding of the threaded column, it is difficult for the support column to maintain a straight movement. Once the load on the feed assembly is large, the rising and falling movement of the support column will be disturbed. At the same time, if the support column and the threaded column disengage from each other, that is, if the rotation of the threaded column exceeds the limit, it will affect the movement of the lifting assembly of this application.

[0017] Therefore, based on the above problem analysis, by setting the length of the limiting rod to not exceed the length of the threaded column, on the one hand, the limiting rod assists the lifting movement of the support column, ensuring the smooth movement of the support column. On the other hand, by setting a blocking block at the top of the limiting rod, the lifting stroke of the support column can be limited by preventing the limiting block from sliding out of the limiting rod. Alternatively, a sensor can be set at the upper end of the limiting rod to detect the sliding position of the limiting block and then control the start and stop of the lifting motor, thereby achieving reasonable stroke movement of the lifting assembly.

[0018] The feed assembly includes a fixed platform, a mounting platform, a limiting bolt, a slide, a movable seat, a feed motor, and a lead screw. The fixed platform is used to mount the drilling machine body and is connected to the mounting platform via the limiting bolt. A slide is connected to the mounting platform and is slidably mounted inside the movable seat. A feed motor is installed inside the movable seat, and the output shaft of the feed motor is connected to a lead screw, which drives the slide to move. The lower end of the movable seat is connected to a lifting assembly.

[0019] A rotary motor is installed between the movable seat and the lifting assembly. The output shaft of the rotary motor is connected to the movable seat, and the lower end of the rotary motor is installed on the lifting end of the lifting assembly. By rotating the upper movable seat through the rotary motor, the drilling machine body on the movable seat can be adjusted to different angles in a timely manner, helping operators to quickly locate the processing position without having to rotate the entire machine again.

[0020] The base is equipped with multiple brake wheels, with a total of four brake wheels. The tops of the four brake wheels are rotatably connected to the bottom of the base. The operator can move the drilling machine with minimal effort by pushing the base. At the same time, the brake wheels are equipped with an automatic locking function to ensure that they will not move during operation.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] 1. The drilling machine for building construction provided in this application, through the cooperation of a folding component, a lifting component and a feeding component, can realize the folding and unfolding, height adjustment and drilling stroke adjustment of the drilling machine, so that the drilling machine can be quickly installed and adjusted while being easy to move, which greatly speeds up the operation efficiency and drilling accuracy.

[0023] 2. The drilling machine for building construction provided in this application is equipped with a slide table, a movable seat, a feed motor and a lead screw to facilitate the adjustment of the drilling position of the drill bit. It is equipped with a rotary motor to facilitate the adjustment of the drilling angle of the drill bit by rotating it horizontally back and forth. It is also equipped with a folding component to facilitate the adjustment of the drilling height of the drill bit according to the usage requirements. At the same time, when the drilling machine is not in use, it can be folded and stored to save space.

[0024] 3. The drilling machine for building construction provided in this application sets the length of the limiting rod to not exceed the length of the threaded column. On the one hand, the limiting rod assists the lifting and lowering movement of the column to ensure the smooth movement of the column. On the other hand, it can also limit the lifting and lowering stroke of the column by limiting the sliding stroke of the limiting block on the limiting rod, thereby effectively avoiding the problem of the lifting component exceeding the limit.

At the same time, when the drilling machine is not in use, it can be folded and stored to save space.

[0040] In this embodiment, as Figure 1 As shown, the second mounting block 318 is externally fixedly connected to a base 320, and the base 320 is externally movably connected to four brake wheels 321. By setting the base 320 and brake wheels 321, the drilling machine can be easily moved, saving manpower for handling.

[0041] exist Figure 1-4 During installation, the top of the fixed platform 301 is fixedly installed at the bottom of the drilling machine body 1. The outer part of the fixed platform 301 is sleeved and installed on the inner side of the top of the mounting platform 302. The mounting platform 302 has a fixed insert plate inside. The bottom inner side of the center position of the fixed platform 301 is inserted and installed on the outside of the insert plate.

The top of the slide table 304 is fixedly installed at the bottom of the center position of the mounting platform 302. The outer part of the slide table 304 is slidably installed on the inner side of the top of the movable seat 305.

[0042] exist Figure 1-4 During installation, the feed motor 306 is externally fixedly mounted inside the front side of the movable seat 305, the front side of the lead screw 307 is fixedly mounted at the rear output shaft of the feed motor 306, the external side of the lead screw 307 is rotatably mounted inside the movable seat 305, the internal thread of the slide table 304 is mounted on the external side of the lead screw 307, and the bottom of the movable seat 305 is fixedly mounted at the top output shaft of the rotary motor 308.

[0043] The implementation principle of this embodiment is as follows: First, by moving the brake wheel 321, the drilling machine is moved to the designated position. After moving to the designated position, the brake wheel 321 is braked and fixed. Then, the first folding motor 316 is started. The first folding motor 316 drives the turntable 312 to rotate inside the first mounting block 315, thereby rotating 180 degrees to adjust the angle of the turntable 312, so that the support column 309 unfolds.

[0044] Next, the second folding motor 319 is started, which drives the support plate 317 to rotate inside the second mounting block 318, thereby rotating 90 degrees to adjust the angle of the support plate 317 and unfolding the support plate 317. Then, the lifting motor 311 is started, which drives the threaded column 310 to rotate. The rotating threaded column 310 causes the support column 309 to move up and down outside, thereby adjusting the drill bit 2 to a suitable drilling position.

[0045] Next, the rotary motor 308 is started, which drives the movable seat 305 to rotate, thereby adjusting the drilling angle of the drill bit 2 by rotating it horizontally back and forth. Finally, the drilling machine body 1 is started, which drives the drill bit 2 to rotate at high speed for pre-drilling. Then, the feed motor 306 is started, which drives the lead screw 307 to rotate. The rotating lead screw 307 causes the slide table 304 to move outside of it, thereby adjusting the position of the drill bit 2 left and right or back and forth for drilling.

[0046] Meanwhile, when the force generated by drill bit 2 during drilling causes the base 320 to move, the worker can step on and press the base 320 to fix it in place. This solves the problem that some existing small construction drilling machines are usually operated manually by hand. Manual operation is time-consuming and laborious, and the vibration of the drilling machine can easily cause injury to the human body. In addition, it is not convenient to drill at high positions by hand. Furthermore, the subjective nature of manual drilling can easily cause deviations in the drilling angle, thus affecting the construction work.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
