For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a top plate drilling device, comprising:

[0031] Support base 1 is equipped with a drilling control mechanism. It should be noted that the operator only needs to hold the support base 1 and turn the handle to make the rope wheel 9 rotate. This allows the wire rope 12 to be wound onto the rope wheel 9. At this time, the moving base 2 can be lifted up until the drill 3 can be moved to the position of the top plate. This drilling process on the top plate can ensure drilling accuracy and safety.

[0032] The drilling control mechanism includes a movable base 2, a drilling rig 3, a side frame 4, a rotating rod 5, a connecting frame 6, a wear-resistant plate 7, a rope winding wheel 9, a wire rope 12, a ratchet 13, a rotating shaft 14, and a pawl 15;

[0033] The movable base 2 is slidably mounted on the support base 1, and the drilling rig 3 is fixedly mounted on the top of the movable base 2. It should be noted that the drilling rig 3 has a certain length of wire to facilitate power connection.

[0034] The side frame 4 is fixedly installed on the side of the support base 1. The rotating rod 5 is rotatably installed on the side frame 4. The connecting frame 6 is fixedly connected to the rotating rod 5. The wear-resistant plate 7 is fixedly installed on the connecting frame 6. The rope wheel 9 and the rotating shaft 14 are both rotatably installed on the connecting frame 6. The wire rope 12 is wound on the rope wheel 9. The ratchet 13 is fixedly sleeved on the outside of the rope wheel 9. The pawl 15 is fixedly sleeved on the outside of the rotating shaft 14. The pawl 15 abuts against the ratchet 13.

[0035] With the above structure, the handle drives the rope wheel 9 to rotate, so that the wire rope 12 is wound onto the rope wheel 9. At this time, the moving seat 2 can be lifted up until the drilling rig 3 can be moved to the position of the top plate. During this process, the rope wheel 9 drives the ratchet 13 to rotate, and the pawl 15 can always abut against the ratchet 13, which can prevent the rope wheel 9 from reversing and can limit the rope wheel 9 to ensure stability.

[0036] After drilling is completed, first push the rotating rod 5 so that the wear plate 7 abuts against the moving seat 2. Then rotate the rotating shaft 14 so that the pawl 15 separates from the ratchet 13. Then the workers control the contact strength between the wear plate 7 and the moving seat 2. This can control the descent speed of the moving seat 2 and prevent the moving seat 2 from falling too fast and causing danger.

[0037] Specifically, the drilling control mechanism also includes a guide rope wheel 10 and two guide rope wheels 11. The guide rope wheel 10 is fixedly installed on the side of the support base 1, and the two guide rope wheels 11 are fixedly installed on the movable base 2. One end of the wire rope 12 passes through the guide rope wheel 10 and the guide rope wheel 11 and is fixedly connected to the bottom of the movable base 2.

[0038] The above structure allows for the guidance of the wire rope 12.

[0039] Specifically, a torsion spring is fixedly installed on the rear side of the rotating shaft 14, and the torsion spring is fixedly connected to the connecting frame 6. A handle is fixedly installed on the rear side of the winding pulley 9. It should be noted that neither the torsion spring nor the handle is shown in the attached drawing. Figure 3 As shown, both the torsion spring and the handle are located on the back of the connecting frame 6. The function of the torsion spring is to apply torsional force to the rotating shaft 14.

[0040] Specifically, a square hole 8 is provided on the side of the support base 1, and the wear-resistant plate 7 passes through the square hole 8. The side of the connecting frame 6 is in contact with the support base 1, and the wear-resistant plate 7 abuts against the movable base 2. It should be noted that when the movable base 2 moves upward normally, the wear-resistant plate 7 does not apply pressure to the movable base 2. When the movable base 2 falls due to gravity, the wear-resistant plate 7 applies pressure to the movable base 2 to prevent the movable base 2 from falling too fast.

[0041] Specifically, a rope hole 16 is provided on the side of the support base 1, through which the wire rope 12 passes. It should be noted that this does not affect the movement of the wire rope 12.

[0042] Working principle:

[0043] S1: Place the device in a suitable position below the top plate of the hole to be drilled. The staff supports the support base 1 to keep it stable. At this time, the moving base 2 is initially in a lower position of the support base 1. The drilling machine 3 has not contacted the top plate. The staff turns the handle on the back of the rope wheel 9. The rope wheel 9 rotates, so that the wound wire rope 12 is gradually tightened. One end of the wire rope 12 is guided by the first guide wheel 10 and the second guide wheel 11 and then connected to the bottom of the moving base 2. As the rope wheel 9 winds up the rope, the wire rope 12 pulls the moving base 2 to slide upward along the support base 1.

[0044] S2: During this process, the rope wheel 9 synchronously drives the outer ratchet 13 to rotate. Because the pawl 15 is subjected to the torsional force of the torsion spring on the rear side of the rotating shaft 14, it always abuts against the ratchet teeth of the ratchet 13, forming a one-way anti-reverse structure. The rope wheel 9 is only allowed to rotate clockwise to drive the moving seat 2 to move upward, avoiding its counterclockwise rotation, ensuring that the moving seat 2 rises stably until the drilling machine 3 reaches the position to be drilled on the top plate. The drilling machine 3 then performs drilling operations on the top plate. Since the upward position of the moving seat 2 is precise and controllable, and the entire device is stably supported by the support seat 1, the verticality of the drilling can be effectively guaranteed, replacing manual high-altitude hand-held electric drill operations and eliminating the risk of falling.

[0045] S3: After drilling is completed, push the rotating rod 5. The rotating rod 5 drives the connecting frame 6 and the wear-resistant plate 7 to rotate synchronously, so that the wear-resistant plate 7 passes through the square hole 8 of the support seat 1 and abuts against the side of the moving seat 2. Rotate the rotating shaft 14 to overcome the torsion spring torque, so that the pawl 15 separates from the ratchet 13, and releases the anti-reverse limit of the rope wheel 9. At this time, the moving seat 2 has a downward sliding tendency due to gravity. The operator controls the rotation angle of the wear-resistant plate 7 driven by the rotating rod 5 to adjust the friction between the wear-resistant plate 7 and the moving seat 2. The greater the friction, the slower the moving seat 2 descends; conversely, the less friction, the faster. Use this friction to achieve uniform and controllable descent and reset of the moving seat 2, preventing equipment impact damage or safety hazards caused by excessive descent.

[0046] The above provides a detailed description of the top plate drilling device provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
