Description

Technical fields: This invention relates to the field of blasting drilling technology, and more particularly to a wall and column drilling device for building blasting. Background technology: Blasting methods are mainly divided into three categories: borehole method, chamber method, and exposed charge method. When using the borehole method for building blasting, it is necessary to drill holes in the walls and columns used for building support to facilitate the fixing of the blasting tubes at each blasting point.

[0001] Publication No. CN 216000978 U discloses a drilling device for installing explosives, including a base plate, a placement frame, a U-shaped plate, and a placement plate. A cylinder is installed at the bottom of the placement frame, and a rack is installed at the output end of the cylinder. A gear is provided on the front of the rack, and a lead screw is fixedly connected to the gear. Through the combination of various structures, this device allows for mechanical replacement of manual drilling during building blasting, thereby improving drilling stability, preventing deviation, reducing the burden on workers, and minimizing dust hazards during drilling.

[0002] The drilling devices in the aforementioned patents and prior art require the operator to hold and push the drilling device continuously during drilling to make it drill. Building walls and columns are usually made of concrete, which has high hardness, making drilling difficult and requiring the operator to push the drilling device continuously, resulting in high physical exertion for the operator. Summary of the Invention: (a) Purpose of the invention In view of this, the purpose of this invention is to provide a wall and column drilling device for building blasting. The technical problem to be solved is that building walls and columns are usually made of concrete, which has high hardness. Drilling is relatively laborious and requires the operator to push the drilling device with force, resulting in a large physical exertion for the operator.

[0003] (II) Technical Solution To achieve the above-mentioned technical objectives, the present invention provides a wall and column drilling device for building demolition: It includes a housing with a rectangular groove on the top. A rectangular plate is slidably connected within the rectangular groove. A support plate is positioned above the rectangular plate, and a drilling device is fixedly mounted on the top of the support plate. Two vertical plates are fixed to the top of the housing, and an annular plate is positioned between the two vertical plates. Two rotating rods are fixed to the outer side of the annular plate, and the ends of the rotating rods away from the annular plate are rotatably connected to the corresponding vertical plates. A pry bar is slidably connected within the annular plate. A first slot is formed within the rectangular plate, and multiple spacers are fixed at equal intervals within the first slot, with gaps between adjacent spacers for the pry bar to pass through. An adjustment mechanism for adjusting the height of the drilling device is provided within the rectangular plate.

[0004] Preferably, a baffle is fixed to the outside of the pry bar, the baffle dividing the pry bar into an upper half H1 and a lower half H2, and the length of the upper half H1 is three times the length of the lower half H2.

[0005] Preferably, guide plates are fixed on both sides of the rectangular plate, and guide grooves are formed on both sides of the rectangular groove, with the guide plates slidingly fitted into the corresponding guide grooves.

[0006] Preferably, a second slot is provided in the rectangular plate, and a bidirectional screw is provided in the second slot. One end of the bidirectional screw is rotatably connected to the inner wall of the second slot through an embedded bearing, and the other end of the bidirectional screw passes through the rectangular plate and is rotatably connected to the rectangular plate.

[0007] Preferably, the adjustment mechanism includes two hinged rods hinged to the bottom of the support plate, and two threaded sleeves are threadedly connected to the bidirectional screw, with the end of the hinged rod away from the support plate hinged to the corresponding threaded sleeve.

[0008] Preferably, the two threaded sections of the bidirectional screw have opposite thread directions, and the two threaded sleeves are located on different threaded sections of the bidirectional screw.

[0009] Preferably, limit rods are fixed at all four corners of the bottom of the support plate, and the limit rods pass through the rectangular plate and slide within the rectangular plate.

[0010] As can be seen from the above technical solutions, this application has the following beneficial effects: 1: Insert the lower half H2 of the lever through the annular plate and between two adjacent partitions. Then, pry the lever to move the rectangular plate. Since the length of the upper half H1 of the lever is three times the length of the lower half H2, the lever forms a lever principle when prying the rectangular plate, which can move the rectangular plate with less effort.

[0011] 2: Rotating the double-acting screw causes the two threaded sleeves to move away from or closer to each other, which in turn causes the threaded sleeves to rotate the hinge rod. When the hinge rod rotates, it causes the support plate and drilling equipment to rise and fall, thereby adjusting the position of the drilling equipment so that the drilling equipment can drill holes in the wall at different locations.

Detailed implementation method: The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0014] Reference Figure 1-4 : Example 1 A wall and column drilling device for building blasting includes a box body 1. Multiple pulleys are installed at the bottom of the box body 1. A push handle is fixed to one side of the box body 1. A rectangular groove 2 is formed at the top of the box body 1. A rectangular plate 3 is slidably connected within the rectangular groove 2. A support plate 4 is positioned above the rectangular plate 3, and a drilling device 5 is fixedly installed on the top of the support plate 4. Two vertical plates 6 are fixed at the top of the box body 1. An annular plate 7 is positioned between the two vertical plates 6. Two rotating rods 8 are fixed to the outer side of the annular plate 7, and the end of the rotating rod 8 away from the annular plate 7 is rotatably connected to the corresponding vertical plate 6. A pry bar 9 is slidably connected within the annular plate 7. A first slot 10 is formed within the rectangular plate 3. Multiple spacers 11 are fixed at equal intervals within the first slot 10, and there is a gap between adjacent spacers 11 for the pry bar 9 to pass through. An adjustment mechanism for adjusting the height of the drilling device 5 is provided within the rectangular plate 3.

[0015] Specifically, a second slot 19 is provided in the rectangular plate 3, and a bidirectional screw 13 is provided in the second slot 19. One end of the bidirectional screw 13 is rotatably connected to the inner wall of the second slot 19 through an embedded bearing. The other end of the bidirectional screw 13 passes through the rectangular plate 3 and is rotatably connected to the rectangular plate 3. The adjustment mechanism includes two hinge rods 15 that are hinged to the bottom of the support plate 4. Two threaded sleeves 14 are threadedly connected to the bidirectional screw 13. The end of the hinge rod 15 away from the support plate 4 is hinged to the corresponding threaded sleeve 14. The two sections of the bidirectional screw 13 have opposite thread directions, and the two threaded sleeves 14 are located on different thread sections of the bidirectional screw 13. Limiting rods 16 are fixed at the four corners of the bottom of the support plate 4. The limiting rods 16 pass through the rectangular plate 3 and slide within the rectangular plate 3.

[0016] It should be noted that, since the two threads of the bidirectional screw 13 are in opposite directions and the two threaded sleeves 14 are located on different threaded sections of the bidirectional screw 13, when the bidirectional screw 13 rotates, it can drive the two threaded sleeves 14 to move closer or further away from each other, thereby driving the hinge rod 15 to rotate, that is, driving the support plate 4 and the drilling equipment 5 to rise and fall. Due to the setting of the limit rod 16, the support plate 4 and the drilling equipment 5 can rise and fall stably.

[0017] Example 2 A wall and column drilling device for building blasting, based on Embodiment 1, has a baffle 12 fixed to the outside of the pry bar 9. The baffle 12 divides the pry bar 9 into an upper half H1 and a lower half H2, and the length of the upper half H1 is three times the length of the lower half H2. Guide plates 18 are fixed on both sides of the rectangular plate 3, and guide grooves 17 are opened on both sides of the groove wall of the rectangular groove 2. The guide plates 18 slide in the corresponding guide grooves 17.

[0018] It should be noted that since the baffle 12 divides the pry bar 9 into an upper half H1 and a lower half H2, and the length of the upper half H1 of the pry bar 9 is three times the length of the lower half H2, the pry bar 9 forms a lever principle when prying the rectangular plate 3 to move, which can pry the rectangular plate 3 to move with less effort. And due to the setting of the guide groove 17 and the guide plate 18, the rectangular plate 3 can move stably in the rectangular groove 2.

[0019] Working principle: The lower half H2 of the pry bar 9 passes through the annular plate 7 and extends into the first slot 10, so that the pry bar 9 is inserted between two adjacent partition bars 11. Then, the pry bar 9 is pried open, so that the pry bar 9 drives the rectangular plate 3 to move. When the rectangular plate 3 moves, it drives the support plate 4 and the drilling device 5 to move, so that the drilling device 5 can drill holes. When it is necessary to drill holes in the wall columns at different locations, the double-acting screw 13 is rotated. When the double-acting screw 13 rotates, it drives the threaded sleeve 14 to move. When the threaded sleeve 14 moves, it drives the hinge rod 15 to rotate. When the hinge rod 15 rotates, it drives the support plate 4 to rise and fall, thereby adjusting the position of the drilling device 5, so that the drilling device 5 can drill holes in the wall at different locations.

[0020] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
