Description

Technical Field

[0001] This utility model relates to the technical field of construction tools, and in particular to a drilling auxiliary support. Background Technology

[0002] During construction, it is often necessary to drill holes in walls or other locations. When the drilling location is high, construction workers can use ladders to assist in the operation; however, when the drilling location is low, construction workers often need to squat down to drill, which is inconvenient and can easily affect the quality of the hole. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the present invention provides a drilling auxiliary support.

[0004] The drilling auxiliary support provided by this utility model adopts the following technical solution:

[0005] A drilling auxiliary support includes a support frame that can move back and forth, a platform plate on the support frame, a clamp for fixing an electric drill on the platform plate, and a lifting mechanism for raising and lowering the platform plate between the platform plate and the support frame.

[0006] By adopting the above technical solution, construction workers can fix the electric drill to the platform plate with clamps, and use the lifting mechanism to move the platform plate up and down to adjust the drilling position. Then, pushing the support frame forward will allow the electric drill to advance and drill, and moving the support frame backward will allow it to exit the drilling position. This drilling auxiliary support is simple and convenient to operate, effectively adapts to drilling tasks at different heights, and makes it more time-saving and labor-saving for construction workers.

[0007] Optionally, the lifting mechanism includes a screw rod vertically disposed on the side of the platform plate, a nut fixed to the top of the support frame, the screw rod being threadedly connected to the nut, and the bottom of the screw rod being rotatably connected to the platform plate.

[0008] By adopting the above technical solution, the construction workers rotate the screw, which moves up and down, thereby driving the platform plate to move up and down, thus effectively changing the drilling height position.

[0009] Optionally, the bottom of the screw passes through the platform plate and is fitted with two stops, one of which is located above the platform plate and the other is located below the platform plate.

[0010] By adopting the above technical solution, the upper and lower stops are used to control the synchronous lifting and lowering of the platform plate and the screw. This structure is easy to manufacture.

[0011] Optionally, the lifting mechanism includes a screw vertically disposed on the side of the platform plate, a second nut fixed to the surface of the platform plate, the screw passing through the platform plate and threadedly connected to the second nut, the top end of the screw being mounted on the top of the support frame via a bearing seat, the bottom end of the screw being mounted on the bottom of the support frame via a bearing seat, and a drive component for driving the screw to rotate being connected to the top end of the screw.

[0012] By adopting the above technical solution, the screw can be driven to rotate by the driving component. The screw cannot move up and down, but when the screw rotates, it drives the platform plate to move up and down.

[0013] Optionally, a drive gear is mounted on the top of one screw and a driven gear is mounted on the top of the other screw, with a drive chain meshing between the drive gear and the driven gear.

[0014] By adopting the above technical solution, the driving gear, driven gear and transmission chain cooperate with each other to make the two screws rotate synchronously, thereby improving the stability of the platform plate moving up and down.

[0015] Optionally, the drive component is a handwheel mounted on the top of the screw.

[0016] By adopting the above technical solution, the handwheel is easy to manufacture and install.

[0017] Optionally, the support frame includes vertically arranged uprights, and the platform plate has a clearance groove at the position corresponding to the uprights. A guide tube is sleeved on the outside of the uprights and the guide tube is fixed to the platform plate.

[0018] By adopting the above technical solution, the platform board can move stably up and down along the upright.

[0019] Optionally, the bottom of the support frame is provided with a translation mechanism, which includes a base plate supported on the ground, a slide rail fixed to the top surface of the base plate, a slider slidably connected to the slide rail, and the bottom end of the support frame is mounted on the slider.

[0020] By adopting the above technical solution, the support frame can move stably back and forth through the cooperation of slider and slide rail, which makes it easy for construction personnel to push or pull the support frame. Attached Figure Description

[0024] The following combination Figures 1-2 The present invention will be described in further detail below.

[0025] This utility model discloses a drilling auxiliary support. Example

[0026] Reference Figure 1 The drilling auxiliary support includes a support frame 1, a translation mechanism 2 located at the bottom of the support frame 1 for moving the support frame 1, a platform plate 3 located on the support frame 1 for supporting the electric drill, a clamp 4 located on the platform plate 3 for fixing the electric drill, and a lifting mechanism 5 located on the support frame 1 for raising and lowering the platform plate 3.

[0027] Reference Figure 1 The support frame 1 is a cuboid frame structure, which includes four vertically arranged uprights 10, and a crossbar 11 is fixed between the tops of two adjacent uprights 10. The translation mechanism 2 includes a base plate 20 supported on the ground, and two parallel slide rails 21 are fixed on the base plate 20. Two sliders 22 are slidably connected to each slide rail 21. The sliders 22 are fixed to the bottom of the corresponding uprights 10, and the sliders 22 are connected to each other as a whole by a connecting plate 23.

[0028] Reference Figure 1 The platform plate 3 is a rectangular plate and is horizontally positioned. A clearance groove 30 is provided on the platform plate 3 at the position corresponding to the upright 10. The upright 10 passes through the clearance groove 30. A guide tube 31 is fixedly connected to the top surface of the platform plate 3 at the position corresponding to the clearance groove 30. The guide tube 31 is adapted to the upright 10 and slidably fitted onto the upright 10. A clamp 4 is installed on the top surface of the platform plate 3, allowing the electric drill to be fixed to the top surface of the platform plate 3.

[0029] Reference Figure 1The lifting mechanism 5 includes screws 50 vertically arranged on the left and right sides of the platform plate 3. A nut 51 is fixedly connected to the outside of the horizontal bar 11 near the screws 50. The screws 50 and the nut 51 are threaded together. The bottom of the screws 50 is rotatably inserted through the platform plate 3. Two stops 52 are fixedly fitted to the bottom of the screws 50. One stop 52 is located above the platform plate 3, and the other stop 52 is located below the platform plate 3, so that the screws 50 can rotate relative to the platform plate 3 and drive the platform plate 3 to move up and down.

[0030] The implementation principle of Example 1 is as follows: The worker fixes the electric drill to the platform plate 3 using clamps 4. By rotating the screw 50, the screw 50 moves up and down, thereby moving the platform plate 3 up and down to adjust the drilling position. Then, pushing the support frame 1 forward allows the electric drill to advance and drill; moving the support frame 1 backward allows it to exit the drilling position. This drilling auxiliary support is simple and convenient to operate, effectively adapting to drilling tasks at different heights, making it more time-saving and labor-saving for construction workers. Example

[0031] Reference Figure 2 The difference between this embodiment and embodiment 1 is that, in addition to the screw 50, the lifting mechanism 5 in this embodiment also includes a second nut 53 fixed to the top surface of the platform plate 3. The screw 50 passes through the platform plate 3 and is threadedly connected to the second nut 53. The top end of the screw 50 is installed on the crossbar 11 through a bearing seat 54, and the bottom end of the screw 50 is installed between the two uprights 10 through a bearing seat 55 and a mounting plate 550. In this embodiment, the screw 50 can only rotate and cannot move up and down.

[0032] Reference Figure 2 One of the screws 50 has a drive gear 56 mounted on its top, and the other screw 50 has a driven gear 57 mounted on its top. A transmission chain 58 meshes between the drive gear 56 and the driven gear 57. A handwheel 59 is also mounted on the top of the screw 50 with the drive gear 56. In other embodiments, a motor mounted on the top of the support frame 1 can also be selected as the drive component according to actual conditions.

[0033] The implementation principle of Example 2 is as follows: The construction worker rotates the screw 50 via handwheel 59. The driving gear 56 drives the driven gear 57 to rotate synchronously via transmission chain 58, allowing both screws 50 to rotate synchronously. Since the screws 50 can only rotate and cannot move up and down, and are threadedly connected to the nut 53, they drive the platform plate 3 to move up and down, thereby changing the drilling height. This lifting mechanism 5 is easier for construction workers to operate and can maintain the synchronous rotation speed of the two screws 50, making the platform plate 3 rise and fall more stably.

[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
