Abstract
Description
Technical Field
[0001] This utility model relates to the field of drilling auxiliary device technology, and in particular to an auxiliary device for electric hammer drilling operations. Background Technology
[0002] Lifting points generally refer to the drilling points where structural components need to be installed on the roof or top during construction. The positions of the lifting points are usually determined by marking lines or various rulers and gauges. Drilling is carried out at the marked positions using a drilling device. The drill is adjusted to accurately align with the drilling point and the position of the drill is fixed. One person is responsible for operating the drilling device, and another person is responsible for controlling the power switch.
[0003] An existing lifting and drilling device (publication number: CN211278273U) has at least the following drawbacks:
[0004] The aforementioned patent allows for positioning and drilling of suspension points on the roof, enabling drilling operations from the bottom up without the need for operators to use auxiliary equipment. The operating lever enables the extension and retraction of the electric hammer drill, greatly improving drilling efficiency. However, manually pressing down on one side of the operating lever makes it difficult to apply greater pushing force to the electric hammer. Furthermore, although the force applied can be reduced using a lever, the torque during pressing is concentrated on the side where the operating lever is pressed down, which can easily cause an imbalance of forces on both sides of the main support rod, leading to a decrease in overall stability and hindering drilling operations. Therefore, it is necessary to propose an auxiliary device for electric hammer drilling to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary device for electric hammer drilling operations.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An auxiliary device for electric hammer drilling includes a fixed tube, a movable tube movably sleeved on the outside of the fixed tube, an electric hammer body disposed on the top surface of the movable tube, and a drilling auxiliary assembly for assisting the electric hammer body in drilling operations. The drilling auxiliary assembly is disposed on the outer circular wall surface of the fixed tube. The drilling auxiliary assembly includes: a support sleeve movably sleeved on the outside of the fixed tube; fixed columns fixedly installed on both sides of the support sleeve; a rotating plate movably sleeved on the outside of the fixed columns; a linkage plate rotatably connected to the outside of the rotating plate; connecting frames fixedly installed on both sides of the movable tube; the connecting frames movably sleeved with the linkage plate; a threaded groove is formed on one side of the rotating plate; and a downward pressure handle is threadedly connected to the inner circular wall surface of the threaded groove.
[0008] As a further embodiment of this utility model, a plurality of limiting holes are provided on one side of the fixed tube, a fixed foot is fixedly installed on one side of the supporting tube sleeve, a pressing plate is movably sleeved on the outside of the fixed foot, a limiting post is fixedly installed on one side of the pressing plate, the limiting post is movably sleeved with the limiting hole, and a second spring is fixedly installed on one side of the supporting tube sleeve, the second spring is fixedly installed with the pressing plate.
[0009] As a further embodiment of this utility model, a first spring is movably sleeved on the outside of the fixed tube, and the first spring is disposed between the support tube sleeve and the movable tube.
[0010] As a further embodiment of this utility model, a support wheel frame is movably sleeved on the outside of the fixed tube.
[0011] As a further embodiment of this utility model, a fixing bracket is fixedly installed on the top surface of the moving tube, and the fixing bracket fixes the electric hammer body through the fixing bracket.
[0012] As a further embodiment of this utility model, a handle sleeve is fixedly sleeved on the outer circular wall surface of the lower pressure handle.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. By using the fixed tube, electric hammer body, moving tube, support sleeve, fixed column, rotating plate and linkage plate in coordination, the electric hammer body can be assisted in drilling. The combined force of the left and right downward pressure handles increases the upward thrust on the electric hammer body. Compared with the single downward pressure handle in the existing technology, it increases the thrust of the electric hammer body while balancing the left and right forces, so that the torque acts symmetrically on both sides of the fixed tube, reducing the deformation of the fixed tube, ensuring overall stability, avoiding affecting the drilling operation, and facilitating drilling of some difficult holes. It is convenient to use and quite practical.
[0015] 2. By manually squeezing and rotating the pressing plate, the limiting post is moved out of the limiting hole, thus releasing the limitation on the moving tube and facilitating the adjustment of the moving tube height. The threaded groove allows for easy removal of either the left or right lower pressure handle when only one needs to be used; simply rotate the lower pressure handle to disengage it from the threaded groove. A first spring supports the moving tube, ensuring the lower pressure handle remains horizontally when not in use for easy gripping. The fixed tube can be removed from the support wheel frame for easy transport. Attached Figure Description

The drilling auxiliary component is disposed on the outer circular wall of the fixed pipe 1. The drilling auxiliary component includes: a support pipe sleeve 4, which is movably sleeved on the outside of the fixed pipe 1; fixed posts 5 are fixedly installed on both sides of the support pipe sleeve 4; a rotating plate 6 is movably sleeved on the outside of the fixed posts 5; a linkage plate 7 is rotatably connected to the outside of the rotating plate 6; connecting frames 8 are fixedly installed on both sides of the movable pipe 3; the connecting frames 8 are movably sleeved with the linkage plate 7; a threaded groove 16 is opened on one side of the rotating plate 6; a downward pressure handle 17 is threadedly connected to the inner circular wall of the threaded groove 16.
[0026] In this embodiment, a plurality of limiting holes 13 are provided on one side of the fixed tube 1, a fixed foot 11 is fixedly installed on one side of the support tube sleeve 4, a pressing plate 12 is movably sleeved on the outside of the fixed foot 11, a limiting post 14 is fixedly installed on one side of the pressing plate 12, the limiting post 14 is movably sleeved with the limiting hole 13, a second spring 15 is fixedly installed on one side of the support tube sleeve 4, the second spring 15 is fixedly installed with the pressing plate 12, a first spring 10 is movably sleeved on the outside of the fixed tube 1, the first spring 10 is disposed between the support tube sleeve 4 and the moving tube 3, a support wheel frame 18 is movably sleeved on the outside of the fixed tube 1, a fixing hoop 19 is fixedly installed on the top surface of the moving tube 3, the fixing hoop 19 fixes the electric hammer body 2 through the fixing hoop, and a handle sleeve 9 is fixedly sleeved on the outer circular wall surface of the lower pressure handle 17.
[0027] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0028] With the fixed tube 1 in place, when the user is drilling holes in the roof concrete or other structures, they can hold the movable tube 3 and push the fixed tube 1 to move under the support of the support wheel frame 18, moving the electric hammer body 2 below the drilling position. Then, by manually squeezing the pressing plate 12 to rotate, the limiting post 14 moves out of the limiting hole 13, pushing the support tube sleeve 4 upward, which drives the first spring 10 to push the movable tube 3 and the electric hammer body 2 upward, making it easy to adjust the height of the movable tube 3. Then, the electric hammer body 2 is moved to below the drilling position, so that there is a slight distance between the electric hammer body 2 and the drilling position, as long as it is not touching the roof concrete. Then, the fixed tube 1 is pushed again to move and position the electric hammer body 2.
[0029] After positioning, two people each hold the handle of the down-pressing handle 17 with their left and right hands and press down to drive the rotating plate 6 to rotate under the support of the fixed column 5. The other end of the rotating fixed column 5 pushes the linkage plate 7 and the connecting frame 8 in the opposite direction. Through the connecting frame 8, the moving tube 3 is pushed upward to push the drill bit of the electric hammer body 2 against the concrete, thereby starting the electric hammer body 2 to start drilling. How to start the electric hammer body 2 is existing technology and will not be described in detail. Then, the two down-pressing handles 17 work together to push the electric hammer body 2 upward. The electric hammer body 2 is directly above the fixed tube 1. While increasing the pushing force, the symmetrical force on the left and right sides reduces the deformation of the fixed tube 1, reduces the lateral rigidity of the fixed tube 1, ensures the overall stability, avoids affecting the drilling operation, and facilitates the construction of some difficult holes.
[0030] With the threaded groove 16, when only one of the left or right lower pressure handles 17 needs to be used, the lower pressure handle 17 can be rotated to disengage from the threaded groove 16 and can be removed. With the first spring 10, the moving tube 3 is supported, so that the lower pressure handle 17 can be kept horizontal when not in use, making it easy to grip the lower pressure handle 17. The fixed tube 1 can be removed by pulling it out from the inside of the support wheel frame 18, which is convenient for transportation, etc.
[0031] This achieves the effect of assisting the drilling operation of the electric hammer body 2. The combined force of the left and right downward pressure handles 17 increases the upward thrust of the electric hammer body 2. Compared with the single downward pressure handle 17 in the prior art, it increases the thrust of the electric hammer body 2 while balancing the left and right forces, so that the torque acts symmetrically on both sides of the fixed pipe 1, reduces the deformation of the fixed pipe 1, avoids affecting the drilling operation, facilitates drilling of some difficult holes, is convenient to use, and is more practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
