[0021] The embodiments of the present invention will now be described with reference to the accompanying drawings. The described embodiments are only some embodiments of the invention, and not all embodiments.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar units or units having the same or similar functions throughout.

[0023] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that terms such as "installation," "connection," and "fixing" should be interpreted broadly, and can refer to direct connection, installation, or fixing, or indirect connection, installation, or fixing. The present invention does not impose any limitations in this regard.

[0024] like Figures 1 to 2 The diagram illustrates an embodiment of a drilling device for high-altitude drilling according to the present invention. It includes a drill support unit comprising a base 61 and an adjusting rod 4 slidably connected to the base 61, the adjusting rod 4 being connected to a drill fixing structure; a height adjustment unit comprising a control lever slidably connected to the base 61 to move closer to or further away from the adjusting rod 4, the control lever being selectively engaged with the adjusting rod 4 and rotating relative to the base 61 in the engaged state to control the movement of the adjusting rod 4; and a locking unit comprising a limiter 65 and a control plate connected to the limiter 65, the control plate being rotatably connected to the base 61 to control the limiter 65 to selectively engage or disengage from the adjusting rod 4. Preferably, the drill fixing structure is a drill support base 1 connected to the adjusting rod 4 for mounting the drill; the base 61 is a box structure; and the control plate is a bent structure with the bent portion rotatably connected to the base 61.

[0025] On the other hand, the present invention also provides a construction method for a high-altitude drilling device, comprising the following steps:

[0026] Place the device at the predetermined drilling location;

[0027] Move the control lever until it engages with the adjusting lever 4;

[0028] The control plate is pressed down and the lever principle is used to control the limit switch 65 to disengage from the adjusting rod 4;

[0029] Rotate the control lever to move the adjusting rod 4 vertically to adjust the height of the electric drill;

[0030] Release the control panel, and the limit switch 65 engages with the adjusting rod 4 to lock the height of the adjusting rod 4.

[0031] This embodiment is easy to operate, eliminating the need for personnel to repeatedly climb to heights, reducing the need for personnel to work at heights, and keeping personnel away from electric drills, thus reducing drilling noise or dust interference and improving the comfort and safety of personnel during the drilling process; its ease of operation can improve construction efficiency and drilling quality.

[0032] The adjusting rod 4 is a toothed rod structure with continuous toothed grooves along its extension direction. The control lever includes a toothed body 63, a rotating shaft, and a control handle 64. The teeth of the toothed body 63 are selectively engaged with the toothed grooves of the adjusting rod 4. The rotating shaft is slidably connected to the base 61, the toothed body 63 is rotatably connected to the rotating shaft, and the control handle 64 is connected to the toothed body 63. Preferably, limiting grooves 62 are provided on both sides of the base 61, and the two ends of the rotating shaft are slidably disposed in the corresponding limiting grooves 62. The limiter 65 is configured to be inserted into the corresponding toothed groove of the adjusting rod 4 to achieve locking. The toothed body 63 is movably sleeved outside the rotating shaft. The vertical movement of the adjusting rod 4 is achieved through the meshing and rotational cooperation of the toothed rod and the toothed rocker arm, and the adjustment is convenient. The locking part locks the adjusting rod 4 through the limiter 65 and the control plate, improving the adjustment stability and making the height adjustment flexible.

[0033] The drill support also includes a sliding member 612 and a first buffer member 68. A groove 613 is formed in the base 61. The sliding member 612 is slidably disposed within the groove 613 and connected to the adjusting rod 4. The first buffer member 68 is connected to the base 61 and corresponds to the end of the adjusting rod 4 furthest from the drill's fixing structure. Preferably, the first buffer member 68 is made of spring and is located below the adjusting rod 4 to buffer the rod's descent. This not only reduces the risk of component damage but also reduces noise caused by mechanical impact during the rod's descent, improving worker comfort and extending the device's lifespan. The cooperation between the sliding member 612 and the groove 613 reduces horizontal offset during the vertical movement of the adjusting rod 4, improving stability and drilling quality.

[0034] The locking mechanism also includes an adjusting spring 610. A base 69 is provided at the bottom of the base 61. A first buffer 68 is disposed inside the base 61 and connected to the base 69. The adjusting spring 610 is disposed outside the base 61 and connected between the control plate and the base 69. The adjusting spring 610 provides cushioning when the control plate is pressed down. Preferably, a caster wheel 611 is provided at the bottom of the base 69. The caster wheel 611 is a universal wheel with a braking structure. The caster wheel 611 facilitates the movement of the device, reduces physical exertion, reduces the burden of handling and moving, and improves construction efficiency.

[0035] In different embodiments, the drill support also includes one or more interlocking standard sections 2. An adjusting rod 4 is detachably connected to a corresponding standard section 2, and the drill fixing structure is connected to the corresponding standard section 2. Preferably, the adjusting rod 4 is connected to the bottom of the lowest standard section 2 via an adapter 3. Each standard section 2 has a stepped design at its top and bottom for easy interlocking. Multiple standard sections 2 can be interlocked as needed to adjust the height of the drill fixing structure. This embodiment allows for rapid coarse height adjustment through the interlocking of standard sections 2, improving construction efficiency.

[0036] In this embodiment, the adjusting rod 4 is marked with a scale 5 along its length. This facilitates reading the adjustment information of the adjusting rod 4, improves drilling positioning accuracy, and enhances construction efficiency and drilling quality.

[0037] In this embodiment, the base 61 has a first mounting hole 614 and a second mounting hole 615. The locking part also includes a transmission limiting rod 67. The control plate includes a control plate body 66 and a connecting rod 661. The limiter 65 is connected to the control plate body 66 through the connecting rod 661. The connection between the connecting rod 661 and the control plate body 66 is rotatably connected to the base 61 through the transmission limiting rod 67. The control plate body 66 extends to the outside of the base 61 through the second mounting hole 615. The operating lever is inserted into the base 61 through the first mounting hole 614. The vertical length of the first mounting hole 614 can also limit the deflection amplitude of the control handle 64, which is convenient for construction personnel to operate and improves the convenience and comfort of operation.

[0038] Preferably, the connecting rod 661, the control plate body 66, and the limiter 65 together form a Z-shaped structure. In the natural state, the connecting rod 661 and the limiter 65 are subjected to gravity, causing the connecting rod 661 to be inclined and tilted towards the adjusting rod 4, driving the limiter 65 to be inserted into the tooth groove of the adjusting rod 4 to achieve locking. The top of the second mounting hole 615 is configured to contact or gap fit with the control plate body 66 in the naturally locked state of the limiter 65 inserted into the tooth groove, so as to limit the degree of inclination of the connecting rod 661 and stabilize the insertion depth of the limiter 65. The adjusting spring 610 is disposed between the bottom of the control plate body 66 and the base 69, providing an upward support force for the control plate body 66. This support force is balanced with the gravity of the rest of the locking part. When the downward pressure on the control plate body 66 is removed, the adjusting spring 610 can also assist the control plate body 66 to be lifted and reset, which facilitates the height locking of the adjusting rod 4.

[0039] The specific working process of this embodiment is as follows:

[0040] The device is moved to a predetermined position by means of the movable wheel 611, and the device is fixed and stable by means of the braking structure of the movable wheel 611.

[0041] The electric drill is fixed to the drill support base 1 of the electric drill fixing structure. The drill height is roughly adjusted by inserting the standard section 2 to initially align the drill with the drilling hole position. The drill is then turned on, and the drill height is adjusted via the adjustment mechanism: the control handle 64 acts as a grip; moving the control handle 64 closer to the adjustment rod 4 until the toothed body 63 engages with the adjustment rod 4; the control plate body 66 acts as a pedal; pressing down the control plate body 66 compresses the adjustment spring 610, and using the lever principle, the limiter 65 is activated via the connecting rod 661. Disengage from adjusting rod 4; press down control handle 64 to drive toothed body 63 to rotate, causing adjusting rod 4 and electric drill to move upward, sliding member 612 to move along the length of slide groove 613 to reduce horizontal swaying of adjusting rod 4; release control plate body 66, under the action of gravity and with the assistance of adjusting spring 610, control plate body 66 lifts up, and drives connecting rod 661 to rotate around transmission limit rod 67 to tilt towards adjusting rod 4, limiter 65 engages with corresponding tooth groove of adjusting rod 4 to lock the height of adjusting rod 4.

[0042] After drilling is completed, the movable control handle 64 disengages the toothed main body 63 from the adjusting rod 4, and the lower control plate main body 66 disengages the limiter 65 from the adjusting rod 4 through the lever principle. The adjusting rod 4 falls back under the action of gravity and is buffered by the first buffer 68.

[0043] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
