Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a cable cutting device for building engineering. Background Technology

[0002] In construction engineering, cable cutting is an essential step in the construction process, requiring the cutting of copper cables and other similar materials.

[0003] Utility model patent CN221312295U discloses a cable cutting device, mainly comprising: a base, a limiting component, and a cutting device. A pair of first supports are mounted on the upper end of the base, and a support rod is installed between the pair of first supports. A gear is mounted on the outer end of the support rod, and the gear is connected to the support rod via a damping shaft. An installation rod is mounted on the upper end of the first supports. In this cable cutting device, the user passes the cable to be used between an abutment block and a cable guide wheel. The abutment block and the cable guide wheel clamp the cable. The user pulls the cable, causing the cable guide wheel to rotate. The cable guide wheel drives the gear teeth to move. Each rotation of the gear points to a corresponding position on the indicator panel. The scale indicates the circumference of one revolution of the wire guide wheel, which is the length of the cable pulled out. Users can judge the length of the pulled-out cable by referring to the scale on the indicator panel, thus controlling the length of the cut cable and improving the convenience of the cutting work. However, when cutting copper cables, the cutting blade is exposed during operation. This method poses a safety risk as workers may accidentally touch the blade during rotation. Furthermore, the high-speed rotation of the cutting blade can easily cause debris to fly into the worker's hands. Summary of the Invention

[0013] According to the above technical solution, a groove is provided on the top outer wall of the workbench, the pulley is fixedly connected to the outer wall of the extrusion block, the pulley is slidably connected to the inner wall of the groove, a rotating groove is provided on the outer wall of the extrusion block, the rotating rod is rotatably connected to the inner wall of the rotating groove, a circular baffle is fixedly connected to the outer wall of the rotating rod, one end of the torsion spring is fixedly connected to the outer wall of the circular baffle, the cleaning plate is fixedly connected to the other end of the torsion spring, the cleaning plate is slidably connected to the top outer wall of the workbench, and the extrusion column is fixedly connected to the inner wall of the cutting protective shell. When the L-shaped rod moves, it drives the connecting rod to move, thereby extruding the inclined block and causing the L-shaped extrusion rod to drive the inclined extrusion plate downward, thereby extruding the extrusion block to slide in the groove. Through the rotating rod, the cleaning plate is driven to move towards the center of the cutting protective shell, thereby pushing dust and debris into the waste collection box.

[0014] This invention provides a cable cutting device for construction engineering. It has the following advantages: 1. This invention incorporates a protective device. When cutting is required, the control motor is activated, causing the circular saw to move downwards and press the clamping rod against the inclined block. The inclined block then moves the baffle to both sides, allowing the circular saw to enter the protective cutting housing for cutting. By controlling the movement of the baffle, the cutting occurs only within the protective cutting housing, solving the problem of exposed cutting tools and rotating parts easily causing cuts, scratches, or entanglements to operators. Furthermore, the left and right movement of the baffle controls the hinge rod to raise and lower the lifting plate. The lifting plate rises when cutting begins and falls after cutting. By controlling the raising and lowering of the lifting plate, the problem of debris flying out of the device during cable cutting, thus preventing accidents, is solved.

[0015] 2. This invention incorporates a straightening and striking device. When the inclined block moves, it moves the L-shaped rod, which in turn causes the connecting plate to press the reset spring. The fixed plate then moves the clamping shell to both sides. This device stretches the copper cable to both sides, solving the problem of uneven cuts caused by the cable being cut while bent, which affects the normal use of the cable later. When the connecting plate moves, it presses the inclined block to move the movable plate downwards. Since there are multiple sets of inclined blocks, the movable plate moves up and down repeatedly, causing the striking rod to repeatedly strike the outer wall of the cable, knocking off impurities attached to the cable. During the cutting process, the cable inevitably has debris that splashes onto the surface, which can cause wear on the cutting blade.

[0016] 3. This invention, through the setting of a cleaning device, when the L-shaped rod moves, it drives the connecting rod to move, thereby squeezing the inclined block three, causing the L-shaped squeezing rod to drive the inclined squeezing plate downward, thus squeezing the squeezing block to slide in the groove. Through the rotating rod, the cleaning plate is driven to move towards the center of the cutting protective shell, thereby pushing dust and debris into the waste collection box. This solves the problem of a large amount of debris being generated during cutting, resulting in a large amount of debris at the cutting point of the cutting blade, which easily leads to impurities adhering to the surface of the cable. Furthermore, by squeezing the squeezing column through the cleaning plate, the cleaning plate rotates on the rotating rod, thereby stretching the torsion spring. The cleaning plate is squeezed and tilted at the cleaning opening. The tilted push plate forms a slope surface, allowing impurities to automatically slide into the collection box under the action of gravity, avoiding the problem of residue caused by friction or electrostatic adsorption during flat pushing.

[0019] 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.

[0020] Please see Figures 1-9One embodiment of the present invention is as follows: a cable cutting device for construction engineering, including a workbench 1, a waste collection box 2 fixedly connected to the bottom outer wall of the workbench 1, a cutting protective shell 3 fixedly connected to the top outer wall of the workbench 1, a control motor 4 fixedly connected to the top outer wall of the workbench 1, a circular saw 5 fixedly connected to the output end of the control motor 4, a protective device 6 for protecting workers fixedly connected to the outer wall of the circular saw 5, a slide rail 9 fixedly connected to the top outer wall of the workbench 1, a clamping shell 10 slidably connected to the inner wall of the slide rail 9, a cylinder 11 fixedly connected to the inner wall of the clamping shell 10, and a clamping claw 12 fixedly connected to the output end of the cylinder 11. By activating the cylinder 11, the clamping claw 12 can be moved. The clamping claw 12 can position the cable and prevent the cable from shifting during cutting. A support frame 13 is fixedly connected to the top outer wall of the workbench 1.

[0021] The protective device 6 includes a pressing rod 61, a wedge block 62, a return spring 63, a fixing plate 64, a baffle 65, a hinge rod 66, a lifting plate 67, and a limiting plate 68. The pressing rod 61 is fixedly connected to the outer wall of the cutting circular saw 5. The wedge block 62 is slidably connected to the top outer wall of the cutting protective shell 3. One end of the return spring 63 is fixedly connected to the outer wall of the wedge block 62. The fixing plate 64 is fixedly connected to the other end of the return spring 63 and to the top outer wall of the cutting protective shell 3. The baffle 65 is fixedly connected to the outer wall of the wedge block 62. A cutting opening is provided on the top outer wall of the cutting protective shell 3. The baffle 65 fits into the cutting opening. One end of the hinge rod 66 is hinged to the outer wall of the baffle 65. The lifting plate 67 is fixedly connected to the other end of the hinge rod 66. The limiting plate 68 is fixedly connected to the top outer wall of the worktable 1. The lifting plate 67 is slidably connected to the inner wall of the limiting plate 68.

[0022] When cutting is required, the control motor 4 is started, the circular saw 5 moves downward and drives the extrusion rod 61 to extrude the inclined block 62. The inclined block 62 drives the baffle 65 to move to both sides, so that the circular saw 5 enters the cutting protective shell 3 for cutting. By controlling the movement of the baffle 65 through this device, the cutting only occurs inside the cutting protective shell 3, which solves the problem that exposed cutting tools and rotating parts can easily cause operators to be cut, scratched or entangled. The left and right movement of the baffle 65 controls the hinge rod 66 to drive the lifting plate 67 to rise and fall. When cutting begins, the lifting plate 67 rises, and after cutting is completed, the lifting plate 67 falls. By controlling the rise and fall of the lifting plate 67, the problem of debris flying out of the device during the cable cutting process, which could lead to accidents, is solved.

[0023] In this example, the copper cable is inserted into the cutting protective shell 3 and placed on the support frame 13. Then, the cylinder 11 is activated to clamp the copper cable with the gripping claw 12. At this time, the control motor 4 is activated to control the cutting circular saw 5 to move downward. Simultaneously, the pressing rod 61 moves downward with the cutting circular saw 5 and presses the wedge block 62. When the wedge block 62 is pressed, it moves to both sides and presses the return spring 63 to move towards the fixed plate 64, thereby driving the baffle 65 to move to both sides with the wedge block 62. After the cutting is completed, the pressing rod 61 moves downward with the cutting... As the circular saw 5 moves upward, the baffle 65 returns to its original position, closing the cutting protective shell 3. By controlling the movement of the baffle 65 on both sides, it prevents the exposed cutting blade and rotating parts from easily causing cuts, scratches, or entanglements to the operator, thus preventing accidents. At the same time, when the baffle 65 moves to both sides, it pulls the hinge rod 66 to move to both sides, thereby pulling the lifting plate 67 upward. When the baffle 65 blocks the cutting edge, the lifting plate 67 enters the limiting plate 68, making it convenient for the staff to observe the copper cables inside the cutting protective shell 3.

[0024] Please see Figures 1-9 Based on the above embodiments, another embodiment of the present invention is as follows: a straightening and striking device 7 is fixedly connected to the outer wall of the protective device 6, and a cleaning device 8 is fixedly connected to the outer wall of the cutting protective shell 3. The straightening and striking device 7 includes an L-shaped rod 71, a connecting plate 72, a limiting rod 73, a second return spring 74, a second fixing plate 75, a third fixing plate 76, a movable plate 77, a second inclined block 78, a third return spring 79, a fourth fixing plate 710, and a striking rod 711. The L-shaped rod 71 is fixedly connected to the outer wall of the first inclined block 62, the connecting plate 72 is fixedly connected to the outer wall of the L-shaped rod 71, the limiting rod 73 is fixedly connected to the outer wall of the connecting plate 72, and one end of the second return spring 74 is fixedly connected to the outer wall of the connecting plate 72. Plate 2 75 is fixedly connected to the other end of the reset spring 2 74. Fixed plate 2 75 is fixedly connected to the top outer wall of the clamping shell 10. Fixed plate 3 76 is fixedly connected to the outer wall of the cutting protective shell 3. Movable plate 77 is slidably connected to the outer wall of the cutting protective shell 3. Inclined block 2 78 is fixedly connected to the top outer wall of the movable plate 77. The outer wall of fixed plate 3 76 has a slot. The top part of inclined block 2 78 is slidably connected to the inner wall of the slot. One end of the reset spring 3 79 is fixedly connected to the bottom outer wall of the movable plate 77. Fixed plate 4 710 is fixedly connected to the other end of the reset spring 3 79. Fixed plate 4 710 is fixedly connected to the outer wall of the cutting protective shell 3. Striking rod 711 is fixedly connected to the bottom outer wall of the movable plate 77.

[0025] When the inclined block 62 moves, it drives the L-shaped rod 71 to move, and drives the connecting plate 72 to squeeze the reset spring 74. Then, the fixed plate 75 causes the clamping shell 10 to move to both sides. This device stretches the copper cable to both sides, which solves the problem of uneven cuts caused by the cable being cut in a bent state, which affects the normal use of the cable later. When the connecting plate 72 moves, it causes the movable plate 77 to move downward by pressing the second inclined block 78. Since there are multiple sets of the second inclined block 78, the movable plate 77 moves up and down, causing the striking rod 711 to repeatedly strike the outer wall of the cable, knocking off the impurities attached to the outer wall of the cable. During the cutting process, the cable will inevitably have debris that splashes onto the surface during the cutting process, which will cause wear on the cutting blade during the cutting process.

[0026] The cleaning device 8 includes a connecting rod 81, a three-sided inclined block 82, a four-sided return spring 83, a five-sided fixing plate 84, an L-shaped extrusion rod 85, a sloping extrusion plate 86, an extrusion block 87, a five-sided return spring 88, a slide 89, a pulley 810, a rotating rod 811, a circular baffle 812, a torsion spring 813, a cleaning plate 814, and an extrusion column 815. The connecting rod 81 is fixedly connected to the outer wall of the L-shaped rod 81. The three-sided inclined block 82 is slidably connected to the outer wall of the cutting protective shell 3. One end of the four-sided return spring 83 is fixedly connected to the outer wall of the three-sided inclined block 82. The five-sided fixing plate 84 is fixedly connected to the other end of the four-sided return spring 83 and to the outer wall of the cutting protective shell 3. The L-shaped extrusion rod 85 is fixedly connected to the outer wall of the three-sided inclined block 82. The sloping extrusion plate 86 is fixedly connected to the outer wall of the L-shaped extrusion rod 85. The extrusion block 87 is slidably connected to the top outer wall of the worktable 1. One end of the return spring 88 is fixedly connected to the outer wall of the extrusion block 87, and the other end of the return spring 88 is fixedly connected to the outer wall of the slide rail 9. A slide groove 89 is provided on the top outer wall of the worktable 1. A pulley 810 is fixedly connected to the outer wall of the extrusion block 87 and slidably connected to the inner wall of the slide groove 89. A rotating groove is provided on the outer wall of the extrusion block 87. A rotating rod 811 is rotatably connected to the inner wall of the rotating groove. A circular baffle 812 is fixedly connected to the outer wall of the rotating rod 811. One end of the torsion spring 813 is fixedly connected to the outer wall of the circular baffle 812. A cleaning plate 814 is fixedly connected to the other end of the torsion spring 813 and slidably connected to the top outer wall of the worktable 1. An extrusion column 815 is fixedly connected to the inner wall of the cutting protective shell 3.

[0027] When the L-shaped rod 71 moves, it drives the connecting rod 81 to move, thereby squeezing the inclined block 3 82 and causing the L-shaped squeezing rod 85 to drive the inclined squeezing plate 86 to move downward, thereby squeezing the squeezing block 87 to slide in the groove 89. Through the rotating rod 811, it drives the cleaning plate 814 to move towards the center of the cutting protective shell 3, thereby pushing dust and debris into the waste collection box 2. This solves the problem that a large amount of debris is generated during cutting, which leads to a large amount of debris at the cutting point of the cutting blade, and easily causes impurities to adhere to the surface of the cable. Then, the cleaning plate 814 squeezes the squeezing column 815, causing the cleaning plate 814 to rotate on the rotating rod 811, thereby stretching the torsion spring 813. The cleaning plate 814 is squeezed and tilted at the cleaning port. The tilted push plate forms a slope, allowing impurities to automatically slide down into the waste collection box 2 under the action of gravity, avoiding the problem of residue caused by friction or electrostatic adsorption when pushing flat.

[0028] In this example, when the straightening and striking device 7 is working, the movement of the inclined block 62 drives the L-shaped rod 71 to move. When the L-shaped rod 71 moves, it drives the connecting plate 72 to move. The connecting plate 72 is moved towards the fixed plate 75 by the action of the limiting rod 73, thereby squeezing the reset spring 74 and driving the fixed plate 75 to move to both sides. This causes the clamping shell 10 to move to both sides of the device. Since the cylinder 11 inside the clamping shell 10 drives the clamping claw 12 to clamp the copper cable, the movement of the clamping shell 10 to both sides at this time can perform... The straightening action is performed, and when the connecting plate 72 moves to both sides, it will squeeze the inclined block 2 78. Since the inclined block 2 78 is provided in multiple sets and fixed above the movable plate 77, when the inclined block 2 78 is squeezed, it will squeeze the movable plate 77, thereby squeezing the return spring 3 79 to move towards the fixed plate 4 710, and driving the striking rod 711 to move downward to complete one strike. When the connecting plate 72 leaves the inclined block 2 78, the return spring 3 79 returns to its original position. At this time, the striking rod 711 leaves the copper cable, and the copper cable is repeatedly struck by the striking rod 711. When the cleaning device 8 is working, the L-shaped rod 71 drives the connecting rod 81 to move to both sides, thereby squeezing the inclined block 3 82. The inclined block 3 82 is squeezed, which in turn squeezes the return spring 4 83 to move towards the fixed plate 5 84, and drives the L-shaped squeezing rod 85 to move downward. The L-shaped squeezing rod 85 drives the inclined squeezing plate 86 to move downward, and squeezes the squeezing block 87. The squeezing block 87 is squeezed and moves towards the return spring 5 88, and slides in the slide groove 89 through the pulley 810 to improve the moving efficiency. When the squeezing block 87 moves towards the slide rail 9, it drives the rotating rod 811 to move towards the slide rail 9 at the same time. The rotating rod 811 drives the cleaning plate 814 to move towards the slide rail 9, and the worktable 1 is topped The part is provided with a cleaning hole. The cleaning plate 814 moves back and forth inside the cutting protective shell 3 to clean the inside of the cutting protective shell 3, so as to prevent excessive debris and other impurities from accumulating inside the cutting protective shell 3 and affecting the cutting effect. When the cleaning plate 814 is about to move to the cleaning hole, the lower half of the cleaning plate 814 will squeeze the extrusion column 815. At this time, the cleaning plate 814 rotates on the outer wall of the rotating rod 811 and tilts at the cleaning hole. At this time, the torsion spring 813 is subjected to tension. When the cleaning plate 814 leaves the extrusion column 815, the torsion spring 813 drives the cleaning plate 814 to return to its original position, thereby dumping the debris and impurities adhering to the cleaning plate 814 into the waste collection box 2.
