Description

Technical Field

[0001] This utility model relates to the field of auxiliary construction equipment for civil engineering, and more specifically to an auxiliary positioning drilling device for concrete structures. Background Technology

[0002] Concrete is a composite material widely used in construction and bridge engineering. It is made by precisely proportioning and mixing cement, water, coarse and fine aggregates, and admixtures as needed. With its excellent structural performance and economy, it is widely used in civil engineering, residential construction and other fields. In order to meet the needs of building or structural modification, repair, reinforcement or installation, it is necessary to use a hole-opening device to open holes in the concrete.

[0003] Currently, drilling operations on concrete structures are usually carried out manually with hand-held drill bits. During the drilling process, it is easy to cause the holes to tilt, or to injure workers with electric drills. Furthermore, when drilling multiple holes, it is impossible to ensure that each row of holes is on the same straight line, which affects the construction of ancillary works such as mechanical and electrical equipment.

[0004] Therefore, how to provide a positioning drilling device that can perform positioning drilling construction, prevent hole tilting, and ensure that multiple holes are in the same straight line is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides an auxiliary positioning drilling device for concrete structures, which can accurately position the drill hole during the drilling process, prevent the hole from tilting, and has a high safety factor; when carrying out row drilling operations, it can ensure that multiple holes in each row are on the same horizontal line, ensuring subsequent stable, efficient, fast and accurate construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A concrete structure auxiliary positioning drilling device, comprising:

[0008] The main frame is slidably connected to the top surface of the structure.

[0009] A first side frame is vertically fixed to one end of the main frame and corresponds to the first side wall of the structure; a first abutment is rotatably connected to the first side frame and can abut against the first side wall.

[0010] The second side frame is vertically fixed to the other end of the main frame and corresponds to the second side wall of the structure; a second abutment is rotatably connected to the second side frame and can abut against the second side wall.

[0011] A fixing plate, which is fixed to the second side frame;

[0012] A rack, one end of which is vertically slidably connected to the fixed plate;

[0013] A drilling rig, wherein the body of the drilling rig meshes with the rack for transmission; the drill bit of the drilling rig corresponds to the second sidewall to perform drilling.

[0014] The beneficial effects of this utility model are that the main frame can travel along the top surface of the structure. When it reaches a preset point, the position of the main frame can be fixed by the first and second abutting parts respectively abutting against the first and second side walls. The rack can be adjusted by moving up and down along the fixed plate so that the drill bit corresponds to the preset point, and drilling is performed by the drilling machine sliding along the rack. This drilling device can ensure the accuracy of the hole position, and at the same time, when performing multiple drilling operations, it can ensure the coaxiality of each row of holes, ensuring the accurate installation of subsequent electromechanical equipment and other auxiliary works.

[0015] Preferably, a roller is rotatably connected within the main frame, and the outer surface of the roller can rotatably abut against the top surface of the structure. The sliding movement of the main frame is achieved by the rolling of the roller on the top surface of the structure.

[0016] Preferably, two opposing support beams are fixed inside the main frame; support shafts are fixed to the opposite side walls of the two support beams, and the rollers are rotatably connected to the support shafts. Using the support beams and support shafts to mount the rollers ensures their effective rolling.

[0017] Preferably, both the first and second abutting members are bolts. The bolts are screwed onto the first or second side frame, and their threaded ends can abut against the first or second side wall to restrict the sliding of the main frame. By screwing the bolts onto the concrete surfaces of the first and second side walls, the position of the main frame is fixed, preventing displacement during drilling.

[0018] Preferably, the threaded end of the bolt is covered with a rubber sleeve. The rubber sleeve prevents the bolt from making rigid contact with the concrete surface, thus preventing damage to the concrete surface, ensuring the overall aesthetics of the structure, and guaranteeing construction quality.

[0019] Preferably, the fixed plate has a sliding groove; one end of the rack is fixed with a slide block; the slide block is slidably connected to the sliding groove. The drilling height position is adjusted by sliding the rack up and down in the sliding groove.

[0020] Preferably, the slide block has an elongated groove corresponding to the sliding groove; a screw passes through the elongated groove and the sliding groove, and a nut is used to fasten the slide block to the fixing plate to restrict the sliding of the slide block. The screw can slide along the elongated groove and the sliding groove. When the drill bit corresponds to the preset hole position, the screw and nut are used to fasten the slide block to the fixing plate to fix the height position of the drill bit.

[0021] Preferably, the slide has threaded holes at its four corners, and the threaded ends of the fastening bolts are screwed into the threaded holes and abut against the panel of the fixing plate. Since the slide is fastened by a single screw and nut to prevent the rack from rotating during drilling, the four corners of the slide are locked by fastening bolts.

[0022] Preferably, the machine body is provided with a gear that meshes with the teeth on the rack; a rotating rod is provided on one side wall of the machine body to drive the gear. The rotation of the rotating rod drives the gear to mesh along the teeth on the rack, thereby realizing the drilling operation.

[0023] Preferably, the main frame, the first side frame, and the second side frame are all square frame structures welded from angle steel; the main frame, the first side frame, and the second side frame are integrally welded together. The drilling device is easy to source materials, simple to manufacture, and has good overall integrity, effectively ensuring accurate drilling operations and the coaxiality of multiple holes.

[0024] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an auxiliary positioning drilling device for concrete structures. The main frame, the first side frame and the second side frame support the drill bit for positioning drilling, ensuring the stability of the drilling process and preventing the hole from tilting. Moreover, when drilling multiple holes, it can ensure the coaxiality between the multiple holes, ensuring the effective installation of subsequent electromechanical equipment and other auxiliary structures.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1 and 2 As shown in the embodiment of this utility model, an auxiliary positioning drilling device for concrete structures comprises a main frame, a first side frame, and a second side frame, which together form a support frame for the drill bit. The horizontal position of the support frame is adjusted by sliding it along the top surface of the structure, and the height of the drill bit is adjusted by sliding it up and down along a fixed plate. The horizontal and vertical position adjustments ensure the accuracy of the drilling position and the verticality of the hole, preventing the drilling from tilting. Furthermore, the movement of the support frame allows for drilling of the entire row, ensuring the coaxiality between multiple holes in each row.

[0031] The positioning drilling device in this embodiment includes a main frame 1, a first side frame 2, a second side frame 3, a fixing plate 4, a rack 5, and a drilling rig 6. The main frame 1 is slidably connected to the top surface of the structure and can be displaced horizontally along the structure. The first side frame 2 is vertically fixed to one end of the main frame 1 and corresponds to the first side wall of the structure. A first abutment 21 is rotatably connected to the first side frame 2 and can abut against the first side wall. The second side frame 3 is vertically fixed to the other end of the main frame 1 and corresponds to the second side wall of the structure. A second abutment 31 is rotatably connected to the second side frame 3 and can abut against the second side wall. The width of the frame is slightly larger than the width of the structure. The first side frame 2 and the second side frame 3 are clamped on both sides of the structure. The sliding of the main frame 1 is restricted by the contact between the first abutment 21 and the second abutment 31 and the side wall of the structure, so as to ensure the stability during the drilling process. The fixing plate 4 is fixed on the second side frame 3. One end of the rack 5 is vertically slidably connected to the fixing plate 4. The body 61 of the drilling machine 6 meshes with the rack 5 for transmission. The body 61 is provided with a gear that meshes with the teeth on the rack 5. A rotating rod 63 is provided on one side wall of the body 61 to drive the gear. The drill bit 62 of the drilling machine 6 corresponds to the second side wall to perform drilling.

[0032] In this embodiment, the main frame 1, the first side frame 2, and the second side frame 3 are all square frame structures welded from angle steel; the main frame 1, the first side frame 2, and the second side frame 3 are integrally welded together.

[0033] When the main frame slides along the top surface of the structure, it drives the first and second side frames to move synchronously. After reaching the preset point, the first and second abutting parts abut against the side walls of the structure, thereby restricting the sliding of the main frame. Then, the rack slides up and down according to the height of the preset point, so that the drill bit corresponds to the preset point. The drill bit is controlled by the rotating rod to move back and forth relative to the structure to perform drilling operations. The drilling equipment of this embodiment can prevent the hole from tilting during the drilling operation, and the construction personnel do not need to hold the drill to perform drilling operations, which has a higher safety factor. When drilling a row of holes, the coaxiality between multiple holes can be guaranteed. When drilling holes of different diameters, only different types of drill bits need to be changed.

[0034] To further optimize the above technical solution and ensure that the main frame 1 can slide stably along the top surface of the structure, a roller 11 is rotatably connected inside the main frame 1, and the outer surface of the roller 11 can rotate and abut against the top surface of the structure. It should be noted that the outer diameter of the roller 11 needs to be slightly larger than the height of the main frame to ensure that the outer circumferential surface of the roller 11 can roll and abut against the top surface of the structure.

[0035] In some other embodiments, two opposing support beams 12 are fixed inside the main frame 1; support shafts 13 are fixed to the opposite side walls of the two support beams 12, and rollers 11 are rotatably connected to the support shafts 13. There are four rollers 11, which are arranged in pairs to ensure that the main frame 1 can slide stably along the top surface of the structure.

[0036] In other specific embodiments, both the first abutment member 21 and the second abutment member 31 are bolts. The bolts are screwed onto the first side frame 2 or the second side frame 3, and their threaded ends can abut against the first side wall or the second side wall to restrict the sliding of the main frame 1. During the movement of the main frame, the threaded ends of the bolts move away from the side wall of the structure. When the main frame reaches a preset position, the bolts are screwed on to abut against the side wall of the structure.

[0037] To further optimize the above technical solution, the second side frame is located on the construction side, i.e., the front of the structure, while the first side frame is located on the back of the structure. To facilitate tightening the bolts, the height of the first side frame is less than the height of the second side frame. The first side frame only needs to ensure that the first abutment can contact the concrete on the back of the structure. The height of the first side frame needs to meet the installation requirements of the fixing plate.

[0038] To further optimize the above technical solution and avoid damage to the structure caused by hard contact between the bolt and the concrete, the threaded end of the bolt is covered with a rubber sleeve 7.

[0039] In this embodiment, a groove 41 is provided on the fixed plate 4; a slide block 51 is fixed to one end of the rack 5; the slide block 51 is slidably connected to the groove 41. The groove 41 is arranged along the height direction of the structure, and the length of the groove 41 is determined according to the preset points on the structure.

[0040] To further optimize the above technical solution, a long groove 53 corresponding to the sliding groove 41 is provided on the slide block 51; the screw passes through the long groove 53 and the sliding groove 41 and fastens the slide block 51 to the fixing plate 4 through the nut to limit the sliding of the slide block 51.

[0041] The sliding range of the slide block is the sum of the lengths of the elongated groove and the sliding channel. There is one screw, which can slide up and down relative to the elongated groove and the sliding channel. When the drill bit is aligned with the preset hole position, the screw and nut are screwed together to fix the slide block to the fixing plate.

[0042] In other specific embodiments, to prevent the rack from deflecting during drilling, threaded holes are provided at the four corners of the slide 51, and the threaded end of the fastening bolt 52 is screwed into the threaded hole and abuts against the panel of the fixing plate 4.

[0043] In some other specific embodiments, the fixing plate has multiple through holes. When the position of the drill bit is such that the fastening bolt corresponds to the through hole, the fastening bolt is locked by the nut to fix the slide and the fixing plate. When the height of the drill bit is misaligned with the through hole, the fastening bolt is screwed in so that its threaded end abuts against the panel of the fixing plate to fix the position of the slide and prevent deflection.

[0044] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
