[0002] A construction site refers to a location where various buildings and infrastructure are under construction. With the rapid development of the construction industry, there are significant differences in building structural forms and floor heights. In traditional building construction, secondary structures, mechanical and electrical installations, and decoration construction often require frequent high-altitude drilling operations (such as implanting steel bars in the floor slab ceiling, installing ceiling suspenders, and fixing pipe supports, etc.).

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] Please refer to Figures 1 - 12 , a drilling assistance device for construction sites, including a drilling machine 1, and further including:

[0050] A bottom rod 2, in which a transfer rod 3 is movably inserted, and a limiting mechanism 4 for restricting the height of the transfer rod 3 is arranged on the bottom rod 2;

[0051] A receiving rod 5 is movably inserted inside the transfer rod 3, and the drilling machine 1 is installed above the receiving rod 5;

[0052] A transmission mechanism 6 is arranged on the transfer rod 3 and is used to drive the receiving rod 5 to move up and down;

[0053] A plurality of support mechanisms 7 are provided and are detachably connected to the bottom rod 2 for supporting the bottom rod 2.

[0054] During use, the drilling machine 1 is installed above the receiving rod 5 of this auxiliary device, so that the drill bit of the drilling machine 1 faces upward. Then, the transfer rod 3 is inserted into the bottom rod 2, and the transfer rod 3 is moved up and down to adjust the height, that is, to adjust the height of the drilling machine 1. After adjustment, the height of the transfer rod 3 can be restricted by the limiting mechanism 4, that is, the drilling machine 1 is at the adjusted height, so that it can be adjusted according to the top of the floor with different storey heights, with strong flexibility and can meet the drilling requirements of the drilling machine 1 with corresponding heights.

[0055] Then, after the drilling machine 1 is started, the construction worker operates the transmission mechanism 6, and the transmission mechanism 6 can drive the receiving rod 5 to move up and down. When the receiving rod 5 moves upward, the receiving rod 5 will drive the drilling machine 1 to move upward synchronously, that is, at this time, the drill bit of the drilling machine 1 will advance and drill. After the drilling machine 1 finishes drilling, the drilling machine 1 is moved downward through the transmission mechanism 6 to disengage from the drilled hole, and then this auxiliary device is transferred to the next construction drilling position, and the above steps are repeated. The drilling operation of this solution is simple and convenient. The construction worker can make the drilling machine 1 drill through this auxiliary device on the ground, without the need to use a scaffold, that is, there is no need to repeatedly set up the scaffold and no need for personnel to repeatedly climb up and down the scaffold for drilling, saving a lot of time and energy, with simple and convenient operation, greatly improving the construction efficiency and accelerating the construction process. And it avoids the risks generated by construction workers repeatedly climbing heights and working at heights on the scaffold, better protecting the safety of construction workers, with good use effects, high practicability, and can be popularized and used.

[0056] When using this auxiliary device, multiple support mechanisms 7 can be respectively connected and installed to the bottom rod 2. Through the multiple support mechanisms 7, the bottom rod 2, the adapter rod 3, and the drilling machine 1 can be supported. Thus, when operating the transmission mechanism 6 to drill with the drilling machine 1, there is no need to hold the bottom rod 2 or the adapter rod 3 by hand, etc. It can enable the drilling machine 1 to perform more stable drilling operations later, prevent the bottom rod 2, the adapter rod 3, and the drilling machine 1 from tilting or even toppling, and can greatly reduce the phenomenon that the drilling machine 1 shifts during drilling, affecting the drilling quality, and better improve the drilling quality of the drilling machine 1. It also reduces the energy consumed by manual holding, and at the same time prevents the threat to construction personnel caused by toppling. During transportation or storage, the support mechanism 7 can be removed and stored separately. At the same time, the adapter rod 3 and the bottom rod 2 can be separated, which can reduce the occupied space and improve the convenience of transportation.

[0057] Among them, the drilling machine 1 is connected to the power supply through an external wire and is controlled to start and stop the electric drilling machine 1 with one key through an externally connected control switch, which is convenient for operation.

[0058] In this embodiment, preferably, please refer to Figure 1 、 Figures 5 - 6 and Figure 8 , the outer part of the bottom rod 2 is provided with an external thread, and the limiting mechanism 4 includes:

[0059] A lifting seat 41, the inner wall of which is provided with an internal thread adapted to the external thread of the bottom rod 2, and a limiting plate 42 is provided on the lifting seat 41;

[0060] A stop rod 43 is arranged on the outer wall of the adapter rod 3, and a through groove 44 adapted to the stop rod 43 is opened on the outer wall of the bottom rod 2.

[0061] Specifically, during use, the lifting seat 41 can be rotated along the outer wall of the bottom rod 2. Through the cooperation of the external thread on the bottom rod 2 and the internal thread in the lifting seat 41, the lifting seat 41 can move up or down while rotating. When inserting the adapter rod 3 into the bottom rod 2, the stop rod 43 of the adapter rod 3 is aligned with the through groove 44 of the bottom rod 2, that is, during the insertion process of the adapter rod 3, the stop rod 43 moves along the through groove 44. When the stop rod 43 lands on the limiting plate 42 of the lifting seat 41, the height of the stop rod 43 and the adapter rod 3 is blocked and limited by the limiting plate 42. By rotating and adjusting the height of the lifting seat 41, the height of the adapter rod 3 can be changed, that is, the height of the drilling machine 1 can be adjusted, and the height of the drilling machine 1 can be slowly fine-tuned, which can improve the accuracy of the drilling height of the drilling machine 1.

[0062] A turning handle 31 is provided on the outer wall of the lifting seat 41. By rotating the turning handle 31, the lifting seat 41 can be driven to rotate, which is convenient for construction personnel to operate and is more labor-saving.

[0063] Preferably, please refer to Figures 1 - 2, the transmission mechanism 6 includes:

[0064] An operating rod 61, one end of which is hinged to the receiving rod 5;

[0065] A transmission rod 62, one end of which is hinged to the operating rod 61 and the other end is hinged to the adapter rod 3.

[0066] Specifically, by pressing down the operating rod 61, the operating rod 61 will rotate along the hinge point with the receiving rod 5, and with the cooperation of the transmission rod 62, the end of the operating rod 61 will drive the receiving rod 5 to rise. When the receiving rod 5 moves upward, it will drive the drilling machine 1 to move upward, that is, the drill bit of the drilling machine 1 can be moved towards the floor slab for drilling. After drilling is completed, rotating the operating rod 61 upward can make the receiving rod 5 drive the drilling machine 1 to move downward, that is, the drill bit can be separated from the drilled hole.

[0067] Preferably, a screw rod 29 is further provided on the operating rod 61, and a pull rod 30 is threadedly connected to the operating rod 61. With this design, when different workers operate, or when the height of the adapter rod 3 is adjusted to be relatively high and it is inconvenient for the construction workers to operate the operating rod 61, at this time, the pull rod 30 can be pressed down to drive the operating rod 61 to rotate, which can meet the use in different situations and by different construction workers, and has a large scope of application. The pull rod 30 can also be rotated to make the pull rod 30 rise or fall along the screw rod 29, so as to adjust the height of the pull rod 30 to reach the optimal operating height.

[0068] Preferably, please refer to Figures 2 - 3 , a chute 8 communicating with its interior is provided on the outer wall of the adapter rod 3, and a sliding rod 9 adapted to the chute 8 is provided on the outer wall of the receiving rod 5;

[0069] A guide rail 10 is provided on the outer wall of the adapter rod 3, a guide seat 11 is slidably connected to the guide rail 10, a positioning rod 12 and a scale line are provided on the guide seat 11, and a fastening bolt 13 is threadedly connected to the guide seat 11.

[0070] With this design, when the receiving rod 5 moves up or down, the receiving rod 5 will drive the sliding rod 9 to move up or down along the sliding groove 8. Before drilling, the movable guide seat 11 slides along the guide rail 10, thereby changing the height position of the positioning rod 12. The distance between the positioning rod 12 and the sliding rod 9 can be adjusted according to the distance that the receiving rod 5 needs to move. When the receiving rod 5 drives the sliding rod 9 to move up to the position of the positioning rod 12, it will be blocked and cannot move anymore. At this time, the construction personnel stop pressing the operating lever 61, indicating that the receiving rod 5 and the drilling machine 1 have been moved up to the position. The upward moving distance of the receiving rod 5 and the drilling machine 1 can be preset by changing the height of the positioning rod 12, thereby ensuring that the drilling depth of the receiving rod 5 and the drilling machine 1 reaches the preset requirement each time, avoiding the situation where the drilling depth is too deep or too shallow, effectively ensuring the drilling accuracy, and high practicality. The distance between the positioning rod 12 and the slide rod 9 can be observed and determined by the scale lines on the guide rail 10. After the height of the positioning rod 12 is adjusted, the fastening bolt 13 is screwed so that its end is against the guide rail 10, thereby fixing the guide seat 11 and the positioning rod 12 at the current height position.

[0071] In this embodiment, preferably, please refer to Figure 1 and Figures 5 - 10 , the supporting mechanism 7 comprises:

[0072] A support column 71 is provided with a connecting member 72, a connecting rod 73 is rotatably connected to the connecting member 72, and the connecting rod 73 is detachably connected to the bottom rod 2;

[0073] The connecting rod 73 is provided with a through hole 74 , and the connecting member 72 is provided with a plug hole 75 matched with the through hole 74 .

[0074] Specifically, when in use, the connecting rod 73 can be rotated along the rotation point of the connecting member 72, so that the connecting rod 73 and the support column 71 are in a vertical state, and the through hole 74 of the connecting rod 73 is aligned with the insertion hole 75 of the connecting member 72, and then the bolt rod is passed through the insertion hole 75 and the through hole 74, and then the nuts are respectively screwed in from both sides of the bolt rod to fix the connecting rod 73. Then, one end of the connecting rod 73 is connected and installed with the bottom rod 2, and the bottom rod 2, the adapter rod 3 and the drilling machine 1 can be supported by the connecting rod 73 and the support column 71. Universal wheels can be installed at the bottom of the support column 71 to facilitate the movement and transfer of the entire device, thereby improving the flexibility and efficiency of drilling.

[0075] In this embodiment, preferably, please refer to Figures 6 - 10 A mounting rod 14 is provided at the end of the connecting rod 73, a mounting opening 15 is opened at the end of the mounting rod 14, an insertion rod 16 adapted to the mounting opening 15 is provided on the outer wall of the bottom rod 2, and a limiting component 17 is provided on the mounting rod 14 for connecting the mounting rod 14 and the insertion rod 16.

[0076] With such a design, the mounting rod 14 at the end of the connecting rod 73 can be aligned with the insertion rod 16, so that the insertion rod 16 is inserted into the mounting opening 15 of the mounting rod 14. After being inserted in place, the mounting rod 14 is restricted by the restricting assembly 17, that is, the mounting rod 14 is connected to the insertion rod 16; when disassembling, the restriction of the restricting assembly 17 can be released, and then the connecting rod 73 and the mounting rod 14 are moved outwards. When the mounting rod 14 finally disengages from the insertion rod 16, the separation of the connecting rod 73 from the bottom rod 2 can be achieved. The installation and disassembly are convenient. During transportation and storage, the connecting rod 73 can be disassembled and moved or stored separately, and the connecting rod 73 is rotated to be parallel to the support column 71, as Figure 10 shown in the state. At this time, it is convenient to carry out transportation or storage.

[0077] In this embodiment, preferably, please refer to Figures 6 - 10 , a fixing hole 18 is formed on the insertion rod 16, and the restricting assembly 17 includes:

[0078] A restricting rod 171 movably penetrates through the outer wall of the mounting rod 14. One end of the restricting rod 171 is provided with a restricting block 172 adapted to the fixing hole 18, and the other end is provided with a pulling plate 173. A first elastic member 174 is provided between the pulling plate 173 and the outer wall of the mounting rod 14. The first elastic member 174 in this application can be a spring.

[0079] Specifically, by pulling the pulling plate 173 upwards, the restricting rod 171 and the restricting block 172 will be driven to move upwards, and the first elastic member 174 will be stretched, so that it is removed from the mounting opening 15. Then, when the insertion rod 16 is inserted into the mounting opening 15 of the mounting rod 14, finally the fixing hole 18 of the insertion rod 16 is at the position of the restricting block 172. After releasing the pulling plate 173, the restricting rod 171 and the restricting block 172 will be driven to move downwards and reset by the resilience of the first elastic member 174, that is, the restricting block 172 will enter the fixing hole 18, so that the mounting rod 14 can be restricted, and the mounting rod 14 and the insertion rod 16 are connected and installed together. The disassembly is the same. After pulling the pulling plate 173, the restricting rod 171 and the restricting block 172 will be driven to move upwards. After the restricting block 172 disengages from the fixing hole 18, the mounting rod 14 can be pulled outwards to separate it from the insertion rod 16.

[0080] Preferably, please refer to Figures 1 - 2 and Figure 4, an ejector rod 19 is movably sleeved outside the receiving rod 5, the drilling machine 1 is installed on the ejector rod 19, a plurality of adjustment holes 20 are formed in the outer wall of the ejector rod 19, and a through hole adapted to the adjustment holes 20 is formed in the upper end of the receiving rod 5. With such a design, the ejector rod 19 can move up and down along the receiving rod 5, thereby adjusting the height of the ejector rod 19, that is, adjusting the height of the drilling machine 1. The approximate height of the drilling machine 1 can be adjusted first through the ejector rod 19. After the ejector rod 19 and the drilling machine 1 are erected, the height of the transfer rod 3 can be finely adjusted through the limiting mechanism 4, that is, the height position of the drilling machine 1 can be adjusted more precisely, and the use effect is good. After adjustment, the bolt rod is inserted into the adjustment holes 20 and the through holes, and then the ejector rod 19 is fixed on the receiving rod 5.

[0081] In this embodiment, preferably, please refer to Figures 1 - 4 and Figures 11 - 12 , the upper end of the ejector rod 19 is detachably connected with a sleeve 21, a telescopic dust-proof cover 22 is movably arranged on the outer wall of the sleeve 21, the drill bit of the drilling machine 1 is located inside the dust-proof cover 22, and a dust suction hose 23 is connected to the dust-proof cover 22. The dust suction hose 23 is externally connected to a dust suction device, and the dust suction fan makes the dust suction hose 23 suck away the dust.

[0082] With such a design, when driving the drilling machine 1 to move up for drilling, the dust generated by drilling will fall into the dust-proof cover 22, and the dust in the dust-proof cover 22 will be sucked away through the dust suction hose 23, which can reduce the scattering and diffusion of dust, avoid dust flying, achieve the purpose of environmental protection and further be beneficial to human health.

[0083] And when the drilling machine 1 moves up for drilling, when the dust-proof cover 22 touches the wall surface, it will be compressed and move downward, that is, the dust-proof cover 22 can always be buckled on the construction wall surface, so that the situation that dust scatters outside the dust-proof cover 22 can be effectively reduced, and the dust removal effect is good.

The second elastic member 26 in this application can be a spring.

[0085] With such a design, when the ejector rod 19 and the drilling machine 1 move up, the dust-proof cover 22 will not move when it touches the wall surface, while the sleeve 21 will move up along the inner wall of the dust-proof cover 22. At this time, the second elastic member 26 will also be compressed. Through the elastic force of the second elastic member 26 on the dust-proof cover 22, the dust-proof cover 22 can always be buckled on the wall surface. After drilling is completed, when the ejector rod 19 and the drilling machine 1 move down, the second elastic member 26 will gradually rebound, that is, finally the dust-proof cover 22 will be reset.
