Description

Technical Field

[0001] This utility model relates to the field of crane beam drilling technology, specifically to a high-precision drilling device for H-section crane beams. Background Technology

[0002] H-section crane beams are a common type of lifting tool. They are beam-shaped structures made of steel plates and are mainly used for lifting and suspending heavy objects. Drilling holes can enhance the rigidity and toughness of H-section crane beams, enabling them to withstand greater pressure and tension during use, reducing the risk of deformation or breakage, and thus improving the safety of lifting operations. At the same time, during installation, the holes can also be used to fix the beam and prevent it from shifting or lowering during operation. During use, the holes can also be used to lift or suspend items, enabling a more flexible working method.

[0003] The existing method for drilling holes on the surface of H-section crane beams generally involves manually adjusting the position of a magnetic drill to drill holes at different locations on the crane beam surface. However, the design and location of the holes need to be precisely calculated and determined to ensure that the structure and strength of the beam remain unchanged. This requires multiple adjustments and positioning before drilling, which is not only cumbersome, but also reduces the accuracy of manual drilling as the number of holes increases.

[0004] Therefore, it is of great importance to design a high-precision drilling device for H-section crane beams to solve the above-mentioned defects. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figures 1-6This utility model provides a technical solution:

[0027] The high-precision drilling device for H-section crane beams includes an adjusting frame 1. Movable frames 2 are movably installed at both the left and right ends inside the adjusting frame 1. Movable wheels 3 are rotatably connected to both the front and rear ends inside the movable frames 2. A bidirectional threaded rod 4 is rotatably connected to the front end inside the adjusting frame 1. The tops of both movable frames 2 are threadedly connected to the bidirectional threaded rod 4 via connecting sleeves 5. A toothed rod 6 is fixedly installed at the rear end of the top of the adjusting frame 1. A movable sleeve 7 is slidably connected to the outer side of the toothed rod 6. A first sliding rod 8 is fixedly installed at the front end of the top of the adjusting frame 1. A first sliding sleeve 9 is slidably connected to the outer side of the first sliding rod 8. A drilling assembly 10 is fixedly connected between the movable sleeve 7 and the first sliding sleeve 9.

[0028] First, a stabilizing frame 201 is fixedly connected to the lower part of both ends of the two sets of moving frames 2. The top of each set of stabilizing frames 201 is rotatably connected to a contact wheel 202. When drilling holes in the H-section crane beam, the double-threaded rod 4 is rotated first, and under the connection of the connecting sleeve 5, the two sets of moving frames 2 move synchronously inside the adjusting frame 1. The two sets of moving frames 2 are opened first, and then the adjusting frame 1 is installed on the outside of the H-section crane beam. Then, the double-threaded rod 4 is reversed to drive the two sets of moving frames 2 to move relative to each other until the moving wheel 3 on the inside of the moving frame 2 is in contact with the outside of the H-section crane beam. At the same time, the contact wheel 202 on the stabilizing frame 201 is in contact with the bottom end of the outside of the H-section crane beam. The moving frame 2 can stably drive the adjusting frame 1 to move on the H-section crane beam. Then, the drilling assembly 10 is used to drill holes at different positions. Thus, when drilling holes on the surface of the H-section crane beam, the operation is not only simple, but the drilling position can also be stably adjusted to improve the drilling accuracy.

[0029] Furthermore, a crank 401 is fixedly installed on the left end of the bidirectional threaded rod 4, and a second sliding rod 402 is fixedly installed on the rear end inside the adjusting frame 1. The tops of the two sets of moving frames 2 are slidably connected to the second sliding rod 402 through the second sliding sleeve 403. When the moving frame 2 is moved, the crank 401 drives the bidirectional threaded rod 4 to rotate, and at the same time, the two sets of moving frames 2 are slidably connected to the second sliding rod 402 through the second sliding sleeve 403, thereby stably driving the moving frame 2 to move, thus facilitating the quick and easy installation of the entire device on the outside of the H-section crane beam.

[0030] Then, a rotating shaft 701 is rotatably connected inside the movable sleeve 7. The outer side of the rotating shaft 701 meshes with the rack 6 through a gear 702. A rotating block 703 is fixedly connected to the rear end of the rotating shaft 701. After the entire device is installed on the outer side of the H-section crane beam, the rotating shaft 701 is rotated through the rotating block 703 according to the drilling position. Under the cooperation of the gear 702 and the rack 6, the movable sleeve 7 is driven to move on the outer side of the rack 6, thereby adjusting the position of the drilling assembly 10 to drill holes at different positions.

[0031] Furthermore, a pointer 704 is fixedly connected to the outer side of the movable sleeve 7. A scale line 705 is provided on the outer side of the gear 6 corresponding to the pointer 704. A locking block 706 is rotatably connected to the top of the movable sleeve 7. A torsion spring 707 is installed at the connection between the locking block 706 and the movable sleeve 7. A slot 708 is opened on the top of the movable sleeve 7 corresponding to the locking block 706. During the movement of the movable sleeve 7, the right end of the locking block 706 is first moved out of the slot 708, so that the right end of the locking block 706 is disengaged from the tooth groove of the gear 6, allowing the movable sleeve 7 to move on the outer side of the gear 6. During the movement, the pointer 704 is observed to stop at the scale line 705. After the adjustment is completed, the locking block 706 is released. Under the action of the torsion spring 707, the right end of the locking block 706 is re-engaged into the inner side of the slot 708 to fix the movable sleeve 7, thereby accurately adjusting the position of the drilling assembly 10 and improving the drilling accuracy.

[0032] Secondly, a locking pin 709 is rotatably connected to the top of the movable sleeve 7 and the left end of the locking block 706. A locking groove 710 is provided at the left end of the locking block 706 corresponding to the locking pin 709. When the movable sleeve 7 is released, the right end of the locking block 706 is moved out of the inside of the groove 708, and the locking pin 709 is rotated to lock it into the inside of the locking groove 710, thereby fixing the locking block 706 and facilitating the adjustment of the position of the movable sleeve 7.

[0033] Finally, the drilling assembly 10 includes a connecting rod 1001 fixedly installed between the movable sleeve 7 and the first sliding sleeve 9. A mounting bracket 1002 is fixedly installed on the outer side of the connecting rod 1001. An electric telescopic rod 1003 is fixedly installed on the top of the mounting bracket 1002. A magnetic drill 1004 is fixedly installed on the drive end of the electric telescopic rod 1003. When the position of the movable sleeve 7 is adjusted, the first sliding sleeve 9 slides on the outer side of the first sliding rod 8, thereby driving the connecting rod 1001 to move stably to adjust the position of the magnetic drill 1004. After the adjustment is completed, the electric telescopic rod 1003 is activated to lower the magnetic drill 1004, and the surface of the H-section crane beam is drilled by the magnetic drill 1004.

[0034] In this embodiment, the specific implementation scenario is as follows: When drilling the H-section crane beam, first rotate the bidirectional threaded rod 4, which, under the connection of the connecting sleeve 5, drives the two sets of moving frames 2 to move synchronously inside the adjusting frame 1. First, open the two sets of moving frames 2, then install the adjusting frame 1 on the outside of the H-section crane beam. Then, reverse the bidirectional threaded rod 4 to drive the two sets of moving frames 2 to move relative to each other until the moving wheels 3 on the inner side of the moving frame 2 are in contact with the outer side of the H-section crane beam. Simultaneously, the contact wheels 202 on the stabilizing frame 201 are in contact with the bottom end of the outer side of the H-section crane beam. The moving frame 2 can stably drive the adjusting frame 1. The frame 1 moves on the H-section crane beam. First, the moving sleeve 7 is moved to the position outside the toothed rod 6 according to the drilling position. During the movement, the pointer 704 is observed to stop at the scale line 705, so as to accurately adjust the position of the drilling assembly 10. After the adjustment is completed, the electric telescopic rod 1003 is activated to lower the magnetic drill 1004. The magnetic drill 1004 is used to drill holes on the surface of the H-section crane beam. The whole operation process is simple and convenient. Compared with the existing drilling method for H-section crane beams, this utility model can improve the convenience of operation and drilling accuracy through design.
