Description
Technical Field
[0001] This invention relates to the field of cutting machine technology, specifically to a cement pole cutting machine with an adjustable cutting angle. Background Technology
[0002] Cement poles, as core components of infrastructure such as power transmission, communication, and lighting, are widely used in various environments. In actual construction, especially when erecting poles in mountainous, sloping, corner, or special terrain, it is often necessary to cut the top or bottom of the cement pole at a specific angle (not a 90° vertical section) to ensure that the pole remains perpendicular to the ground after erection or to meet specific installation requirements. Operators manually draw cutting lines on the cement pole using tools such as angle gauges and levels, and then use handheld angle grinders or hydraulic wall saws to cut along the lines. This process relies entirely on the worker's experience and skill, and the cutting angle is prone to deviation, causing the pole to tilt after erection, affecting project quality and safety. The entire process of marking, fixing, and cutting is time-consuming and labor-intensive. Handling high-speed rotating cutting tools generates a lot of dust and is prone to dangers such as shard breakage and tool rebound. It places extremely high demands on the operator's skills and safety protection. Uneven cuts and chipping are also common problems during the cutting process.
[0003] Traditional equipment requires manual marking of the pole beforehand to cut angles, and the cement pole must be tilted and placed at an angle. This is extremely difficult and dangerous, and the accuracy cannot be guaranteed. Summary of the Invention
[0004] To achieve the above objectives, the present invention provides the following technical solution: a cement pole cutting machine with an adjustable cutting angle, comprising a base, a support fixedly connected to the top of the base, a rotating device fixedly connected to the top of the support, a cutting machine fixedly connected to the side of the rotating device, a cleaning device fixedly connected to the inner wall of the rotating device, a guide device fixedly connected to the top of the support located on one side of the rotating device, and the bottom of the guide device fixedly connected to the top of the base via a support. The rotating device includes a rotating sleeve, a slide bar fixedly connected to the top of the rotating sleeve, a movable bracket folded and slidably connected to the top of the slide bar, a movable end of a spring rod fixedly connected to the side of the movable bracket, a push handle fixedly connected to the side of the movable bracket, a protective top fixedly connected to the top of the movable bracket, a rotating assembly fixedly connected to the inner wall of the rotating sleeve, a fixed end of the spring rod fixedly connected to the top of the rotating sleeve via the bracket, and a bottom of the rotating assembly fixedly connected to the top of the equipment support. When the cutting machine is started, the rotating part of the cutting machine rotates to cut the cement column, and the movable bracket is moved by pushing the handle. The moving frame drives the cutting machine to cut the cement column. During the pushing process, when the handle pushes the moving bracket along the top of the slide bar, the spring rod is pulled and generates elastic force, which drives the moving bracket to move back, thus facilitating reciprocating cutting. When cutting different materials and vibration occurs, it is easy to detach from the cement column, thus avoiding problems such as blade breakage during cutting. At the same time, the rotating component drives the rotating sleeve to move, which facilitates the adjustment of the cutting machine to different cutting angles. The rotation direction of the cutting machine also drives dust and debris downwards, which facilitates the collection and treatment of dust. The protective top is designed to prevent debris from flying out.
[0005] Preferably, the rotating assembly includes a rotating base, a rotating gear ring fixedly connected to the top of the rotating base, a sliding ring fixedly connected to the inner wall of the rotating gear ring, an upper sliding ring fixedly connected to the side of the sliding ring via a bracket, a moving assembly slidably connected to the sides of the sliding ring and the upper sliding ring, a fastening assembly slidably connected to the inner wall of the moving assembly, a bottom of the rotating base fixedly connected to the top of the equipment bracket, and a rotating sleeve sleeved on the side of the rotating base and rotatably connected to the rotating base.
[0006] Preferably, the moving component includes a moving block, a positioning hole and a sliding hole on the side of the moving block, a first threaded strip on the inner wall of the sliding hole, a guide groove on the side of the sliding hole, an arc-shaped slide bar fixedly connected to the side of the moving block, the moving block being slidably connected to the side of the lower sliding ring via the arc-shaped slide bar, and the moving block being slidably connected to the side of the upper sliding ring via the arc-shaped slide bar.
[0007] Preferably, the fastening assembly includes a rotating column, a second threaded strip fixedly connected to the side of the rotating column, a rotating handle rotatably connected to the side of the rotating column via a bracket, an adjusting gear fixedly connected to the end of the rotating column away from the rotating handle, a stud fixedly connected to the side of the adjusting gear, a limit rod fixedly connected to the side of the stud, the limit rod penetrating the side of the positioning hole and slidably connected to the positioning hole, the stud being threadedly connected to the first threaded strip, and the rotating column being threadedly connected to the side of the rotating sleeve via the second threaded strip. When adjusting the angle, the rotating handle is directly rotated, causing the rotating column to rotate, which in turn causes the adjusting gear to rotate. The rotating gear, under the action of meshing with the rotating gear ring, causes the rotating sleeve to rotate along the top of the rotating base, thus completing the fine-tuning of the angle. After the angle adjustment is complete, the rotating column is pushed, and the rotating column moves along the side of the rotating sleeve. After movement, the stud engages with the first threaded strip. During engagement, the rotating column drives the second threaded strip to engage with the thread on the side of the rotating sleeve. This achieves threaded fixation through the threaded engagement of the stud with the first threaded strip and the threaded engagement of the second threaded strip with the side of the rotating sleeve. As the rotating column pushes, it causes the adjusting gear to disengage from the top of the rotating gear ring, preventing angular deviation during threaded engagement. After adjustment, the rotating handle rotates along the side of the rotating column, bringing the side of the rotating handle into contact with the bottom of the rotating sleeve. This fixes the rotating column in the direction of rotation, preventing loosening during cutting. The limiting rod facilitates the movement of the moving block along the sides of the lower and upper sliding rings during angle adjustment, ensuring a secure connection between the moving block and the rotating sleeve and maintaining a stable position after angle adjustment.
[0008] Preferably, the cleaning device includes a collection tank, a guide tip fixedly connected to the bottom of the inner wall of the collection tank, a ventilation pipe fixedly connected to the top of the collection tank, ventilation holes on the side of the ventilation pipe, an exhaust fan rotatably connected to the inner wall of the ventilation pipe, a conical tube connected to the top of the ventilation pipe, the top of the conical tube connected to the bottom of the rotating base, and the bottom of the guide tip fixedly connected to the top of the equipment support. During cutting, the dust and debris move vertically downwards, with the debris directly entering the interior of the conical tube. The exhaust fan is activated, rotating and driving air along the top of the conical tube, creating negative pressure at the top of the tube, thus facilitating dust collection. The dust and air move along the ventilation pipe and are directly sprayed onto the top of the guide tip for guidance, while the air overflows through the ventilation holes. Simultaneously, the dust and debris directly enter the water flow inside the collection tank, facilitating the collection and cleaning of dust and debris.
[0009] Preferably, the guiding device includes a rotating shaft, a triangular bracket is rotatably connected through and to the side of the rotating shaft, a limit post is fixedly connected to the side of the triangular bracket, a roller assembly is rotatably connected to the side of the triangular bracket, one end of the rotating shaft is fixedly connected to the top of the equipment bracket through the bracket, and the other end of the rotating shaft away from the equipment bracket is fixedly connected to the side of the rotating base through the bracket.
[0010] Preferably, the roller assembly includes a rotating bracket, a movable column fixedly connected to the bottom of the rotating bracket, a transverse bracket fixedly connected to the top side of the rotating bracket, a transverse roller rotatably connected to the side of the transverse bracket, a positioning groove formed on the side of the transverse roller, and a side of the rotating bracket rotatably connected to the side of the triangular bracket via a rotating shaft. The side of the movable column contacts the side of the limiting column. The cement column is placed directly on the side of the transverse roller. The gravity of the cement column drives the transverse roller to move, the movement of the transverse roller drives the transverse bracket to move, and the movement of the transverse bracket drives the movable column to rotate along the side of the triangular bracket. The moving column and the limiting column work together to adjust the angle of movement. The rotational connection between the triangular bracket and the rotating shaft enables multiple sets of transverse rollers to guide and position the cement column, thus facilitating the movement of the cement column along the side of the transverse roller. The positioning groove guides the cement column, facilitating its movement for cutting at different locations.
[0011] This invention provides a cement pole cutting machine with an adjustable cutting angle. It has the following beneficial effects: 1. This adjustable-angle cement pole cutting machine is equipped with a cutting machine. The rotating part of the cutting machine rotates to cut the cement column. By pushing the handle, a moving bracket is moved, which in turn moves the cutting machine to cut the cement column. During the pushing process, when the handle pushes the moving bracket along the top of the slide bar, the spring rod is pulled and generates elastic force, which drives the moving bracket to move back, thus facilitating reciprocating cutting. When different materials vibrate during cutting, it is easy to detach from the cement column, thus avoiding problems such as blade breakage during cutting. At the same time, the rotating component drives the rotating sleeve to move, which facilitates the adjustment of the cutting machine to different cutting angles. The rotation direction of the cutting machine also moves dust and debris downwards, which facilitates the collection and treatment of dust. The protective top is designed to prevent debris from flying out.
[0012] 2. This adjustable-angle cement pole cutter is equipped with a rotating column. To adjust the angle, simply rotate the handle. The rotating handle rotates the rotating column, which in turn rotates the adjusting gear. The adjusting gear, in conjunction with the rotating gear ring, drives the rotating sleeve to rotate along the top of the rotating base, thus completing the fine-tuning of the angle. After the angle adjustment is complete, push the rotating column. The rotating column moves along the side of the rotating sleeve, causing the stud to engage with the first threaded strip. During engagement, the rotating column drives the second threaded strip to engage with the thread on the side of the rotating sleeve. This engagement, through the threaded cooperation between the stud and the first threaded strip, and the interaction between the second threaded strip and the rotating sleeve, achieves the desired effect. The threaded engagement on the side of the sleeve achieves threaded fixation. During the pushing process of the rotating column, the rotating column drives the adjusting gear to disengage from the top of the rotating gear ring, thereby preventing angular deviation during the threaded engagement. After adjustment, the rotating handle is rotated along the side of the rotating column, so that the side of the rotating handle contacts the bottom of the rotating sleeve, thus fixing the rotating column in the direction of rotation and preventing loosening during cutting. At the same time, the setting of the limit rod facilitates the movement of the moving block along the sides of the lower and upper sliding rings when adjusting the angle, thereby facilitating the tightening between the moving block and the rotating sleeve, and ensuring a stable position after the angle adjustment is completed.
[0013] 3. This adjustable-angle cement pole cutter is equipped with a tapered tube. During cutting, the dust and debris move vertically downwards, directly entering the interior of the tapered tube. The exhaust fan, when activated, rotates, driving air along the top of the tapered tube, creating negative pressure. This facilitates dust collection. The dust and air move along the ventilation duct, directly spraying onto the top of the guide tip for guidance, while the air overflows through the ventilation holes. Simultaneously, the dust and debris directly enter the water flow inside the collection tank, facilitating dust and debris collection and cleaning.
[0014] 4. This adjustable-angle cement pole cutting machine is equipped with transverse rollers. The cement column is placed directly on the side of the transverse rollers. The weight of the cement column drives the transverse rollers to move. The movement of the transverse rollers drives the transverse support to move. The movement of the transverse support drives the moving column to rotate along the side of the triangular support. The moving column and the limiting column work together to adjust the movement angle. The rotational connection between the triangular support and the rotating shaft enables multiple sets of transverse rollers to guide and position the cement column, thus facilitating the movement of the cement column along the side of the transverse rollers. The positioning groove guides the cement column, making it easy to move the cement column and cut at different positions. Attached Figure Description

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] For the first embodiment, please refer to... Figures 1-2The present invention provides a technical solution: a cement pole cutting machine with adjustable cutting angle, including a base 1, a support 2 fixedly connected to the top of the base 1, a rotating device 3 fixedly connected to the top of the support 2, a cutting machine 4 fixedly connected to the side of the rotating device 3, a cleaning device 5 fixedly connected to the inner wall of the rotating device 3, a guide device 6 fixedly connected to the top of the support 2 at a position on one side of the rotating device 3, and the bottom of the guide device 6 fixedly connected to the top of the base 1 through a bracket; The equipment base 1 and equipment bracket 2 support the equipment. The rotating device 3 adjusts and fixes the angle of the cutting machine 4. By continuously adjusting and adapting to different cutting angles, it is easy to cut the cement column. The cement rod is cut by the cutting machine 4. At the same time, the negative pressure generated by the cleaning device 5 in the cutting area causes the cutting dust and other materials to fall into the interior of the cleaning device 5 for collection. The cement rod is moved by the guide device 6, which facilitates the movement of the cement rod on the top of the equipment bracket 2, thus making it easy to cut at different positions.
[0019] The rotating device 3 includes a rotating sleeve 301, a slide bar 302 fixedly connected to the top of the rotating sleeve 301, a movable bracket 303 folded and slidably connected to the top of the slide bar 302, a movable end of a spring rod 304 fixedly connected to the side of the movable bracket 303, a push handle 305 fixedly connected to the side of the movable bracket 303, a protective top 306 fixedly connected to the top of the movable bracket 303, a rotating assembly 308 fixedly connected to the inner wall of the rotating sleeve 301, a fixed end of the spring rod 304 fixedly connected to the top of the rotating sleeve 301 via a bracket, and a bottom of the rotating assembly 308 fixedly connected to the top of the equipment bracket 2.
[0020] When the cutting machine 4 is started, its rotating part cuts the cement column. Pushing the handle 305 moves the movable support 303, which in turn moves the cutting machine 4, thus cutting the cement column. During this process, when the handle 305 pushes the movable support 303 along the top of the slide bar 302, the spring rod 304 is pulled, generating elasticity, which moves the movable support 303 back. This facilitates reciprocating cutting and allows the machine to detach from the cement column when it vibrates while cutting different materials, preventing blade breakage. Simultaneously, the rotating component 308 moves the rotating sleeve 301, allowing for adjustments to the cutting angle. The rotation of the cutting machine 4 also moves dust and debris downwards, facilitating dust collection. The protective top 306 prevents debris from flying out.
[0021] Second embodiment, please refer to Figures 1-5Based on the first embodiment, the present invention provides a technical solution: the rotating assembly 308 includes a rotating base 3081, a rotating gear ring 3082 fixedly connected to the top of the rotating base 3081, a lower sliding ring 3083 fixedly connected to the inner wall of the rotating gear ring 3082, an upper sliding ring 3084 fixedly connected to the side of the lower sliding ring 3083 via a bracket, a moving assembly 3085 slidably connected to the sides of the lower sliding ring 3083 and the upper sliding ring 3084, a fastening assembly 3086 slidably connected to the inner wall of the moving assembly 3085, the bottom of the rotating base 3081 fixedly connected to the top of the equipment bracket 2, and a rotating sleeve 301 sleeved on the side of the rotating base 3081 and rotatably connected to the rotating base 3081.
[0022] The moving component 3085 includes a moving block 30851. A positioning hole 30852 is provided on the side of the moving block 30851. A sliding hole 30853 is provided on the side of the moving block 30851. A first threaded strip 30854 is provided on the inner wall of the sliding hole 30853. A guide groove 30855 is provided on the side of the sliding hole 30853. An arc-shaped slide bar 30856 is fixedly connected to the side of the moving block 30851. The moving block 30851 is slidably connected to the side of the lower sliding ring 3083 through the arc-shaped slide bar 30856. The moving block 30851 is also slidably connected to the side of the upper sliding ring 3084 through the arc-shaped slide bar 30856.
[0023] The fastening assembly 3086 includes a rotating column 30861, a second threaded bar 30862 fixedly connected to the side of the rotating column 30861, a rotating handle 30863 rotatably connected to the side of the rotating column 30861 via a bracket, an adjusting gear 30864 fixedly connected to the end of the rotating column 30861 away from the rotating handle 30863, a stud 30865 fixedly connected to the side of the adjusting gear 30864, a limit rod 30866 fixedly connected to the side of the stud 30865, the limit rod 30866 passing through the side of the positioning hole 30852 and slidably connected to the positioning hole 30852, the stud 30865 threadedly connected to the first threaded bar 30854, and the rotating column 30861 threadedly connected to the side of the rotating sleeve 301 via the second threaded bar 30862.
[0024] When adjusting the angle, directly rotate the handle 30863. Rotating the handle 30863 causes the rotating column 30861 to rotate, which in turn drives the adjusting gear 30864 to rotate. The adjusting gear 30864, in conjunction with the rotating gear ring 3082, causes the rotating sleeve 301 to rotate along the top of the rotating base 3081, thus completing the fine-tuning of the angle. After the angle adjustment is complete, push the rotating column 30861. The rotating column 30861 moves along the side of the rotating sleeve 301, causing the stud 30865 to engage with the first threaded bar 30854. During this engagement, the rotating column 30861 drives the second threaded bar 30862 to engage with the thread on the side of the rotating sleeve 301. Thus, through the threaded engagement of the stud 30865 and the first threaded bar 30854, and the second threaded bar 30862... The threaded engagement with the side of the rotating sleeve 301 achieves threaded fixation. During the pushing process of the rotating column 30861, the rotating column 30861 drives the adjusting gear 30864 to disengage from the top of the rotating gear ring 3082, thereby preventing angular deviation during the threaded engagement. After adjustment, the rotating handle 30863 is driven to rotate along the side of the rotating column 30861, so that the side of the rotating handle 30863 contacts the bottom of the rotating sleeve 301, thereby fixing the rotating column 30861 in the rotational direction and preventing loosening during the cutting process. At the same time, the setting of the limiting rod 30866 facilitates the movement of the moving block 30851 along the side of the lower sliding ring 3083 and the upper sliding ring 3084 when adjusting the angle, thereby facilitating the tightening between the moving block 30851 and the rotating sleeve 301, thus ensuring a stable position after the angle adjustment is completed.

[0026] During cutting, the dust and debris move vertically downwards, directly entering the interior of the conical tube 506. The exhaust fan 505 is activated, rotating and driving air along the top of the conical tube 506, creating negative pressure that facilitates dust collection. The dust and air move along the ventilation duct 503 and are directly sprayed onto the top of the guide tip 502 for guidance. The air overflows through the ventilation holes 504. Simultaneously, the dust and debris enter the water flow inside the collection pool 501, facilitating collection and cleaning.

[0028] The roller assembly 604 includes a rotating bracket 6041, a movable column 6042 fixedly connected to the bottom of the rotating bracket 6041, a transverse bracket 6043 fixedly connected to the top side of the rotating bracket 6041, a transverse roller 6044 rotatably connected to the side of the transverse bracket 6043, a positioning groove 6045 provided on the side of the transverse roller 6044, and the side of the rotating bracket 6041 rotatably connected to the side of the triangular bracket 602 via a rotating shaft. The side of the movable column 6042 contacts the side of the limiting column 603.
[0029] The cement column is placed directly on the side of the transverse roller 6044. The weight of the cement column drives the transverse roller 6044 to move. The movement of the transverse roller 6044 drives the transverse support 6043 to move. The movement of the transverse support 6043 drives the moving column 6042 to rotate along the side of the triangular support 602. The moving column 6042 and the limiting column 603 work together to adjust the angle of movement. The rotational connection between the triangular support 602 and the rotating shaft 601 enables the multiple sets of transverse rollers 6044 to guide and position the cement column, thus facilitating the movement of the cement column along the side of the transverse roller 6044. Under the action of the positioning groove 6045, the cement column is guided, thus facilitating the movement of the cement column for cutting at different positions.
