Description

Technical Field

[0002] In the field of modern industry and construction, cable trays are widely used as key facilities for laying cables, covering multiple industries such as electricity, communications, and construction. With the rapid development of various industries, the demand for cable trays has put forward higher requirements in terms of quantity and quality, which makes the production technology of cable trays face many challenges. When making bridge elbows, such as horizontal or vertical turns, it is necessary to manually cut triangles on both sides of the bridge and scratch the bottom surface for subsequent bending. However, this manual cutting method has many disadvantages. From the perspective of efficiency, manual operation is slow, and it takes a lot of time to complete the cutting of a cable tray. The cutting accuracy is also difficult to guarantee. For example, the angle and side length of the cut triangle have large deviations, and the depth of the bottom scratch is inconsistent. These errors will affect the subsequent bending accuracy and overall quality of the cable tray.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Therefore, through the coordination between various components, the present solution enables the cable tray to complete a series of operations such as vertical cutting of the two side walls, bottom scratching, position limiting and side wall beveling in sequence after being placed in the specified position. Among them, the swing cutting component 2, the adjustment component 3, the alternating swinging component 4 and the scratching component 5 can synchronously complete the straight line cutting and bottom scratching of the side wall of the cable tray, and then the beveling component 7 is used to perform beveling, which avoids the tedious process of manual cutting under the traditional method as a whole, greatly shortens the overall cutting time, and improves production efficiency.

[0037] Embodiment 2: Based on embodiment 1, this embodiment is to achieve the effect of synchronously completing the straight-line cutting of both side walls of the bridge frame and the scratching of the bottom.

[0038] See also Figure 1-7 The swing cutting assembly 2 includes two support seats 21 fixedly connected to the upper end of the workbench 1, the upper ends of the two support seats 21 are commonly fixedly connected to a fixed table 22, a sliding groove 221 is provided on the upper side of the front end of the fixed table 22, a U-shaped groove 222 is provided at the front end of the fixed table 22, a fixed seat 23 is fixedly connected to the rear end of the fixed table 22, a motor 24 is fixedly installed at the front end of the fixed seat 23, a rotating arm 25 is fixedly connected to the output end of the motor 24, and a limiting block 251 is fixedly connected to the front end of the rotating arm 25, the upper ends of the two support seats 21 are commonly fixedly connected to a support frame 26, and a swing arm 27 is rotatably connected to the front end of the support frame 26, the inner surface of the swing arm 27 is slidably connected to the outer surface of the limiting block 251, the front end of the swing arm 27 is fixedly connected to a sector tooth 28, and the lower end of the sector tooth 28 is meshingly connected to a gear 29, the front end of the gear 29 is fixedly connected to a rotating shaft 210, and the outer surface of the rotating shaft 210 is rotatably connected to the fixed table 22.

[0039] Specifically, the sliding groove 221 can limit the sliding block 214 so that it can slide left and right stably;

[0040] Furthermore, when the gear 29 is meshed with the sector teeth 28, the gear 29 will continuously rotate half a circle back and forth, and drive the rotating shaft 1 210 and the connecting shaft 1 211 to rotate together;

[0041] The sliding connection between the first connecting shaft 211 and the second connecting shaft 212 is to prevent the second limiting block 213 from getting stuck when rotating in the U-shaped groove 222 .

[0042] See also Figure 2-4The front end of the rotating shaft 210 is fixedly connected to the connecting shaft 1 211, the inner surface of the connecting shaft 1 211 is slidably connected to the connecting shaft 2 212, the rear end of the connecting shaft 212 is rotatably connected to the limiting block 213, the outer surface of the limiting block 213 is slidably connected to the U-shaped groove 222, the inner surface of the sliding groove 221 is slidably connected to the sliding block 214, the inner surface of the sliding block 214 is slidably connected to the lifting seat 215, the lower end of the lifting seat 215 is fixedly installed with a circular saw 1 216, and a laser ranging sensor 1 217 is arranged on one side of the through groove 11.

[0043] The laser distance sensor 217 mentioned above is a phase-type laser distance sensor in the prior art, which is mainly composed of a laser transmitting module, a laser receiving module, a modulator, a signal processor and a communication module. It calculates the distance by modulating the emitted laser and then comparing the phase difference between the emitted light and the received light;

[0044] When the cable tray moves forward, the sensor works as follows: the laser transmitting module, under the action of the modulator, emits a continuous laser beam modulated by a specific frequency. This laser beam is directed to the cable tray. The laser is reflected after encountering the cable tray. The reflected light is received by the laser receiving module. As the tray moves forward, the propagation distance of the reflected light changes, and a phase difference will occur between the received light and the emitted light. The signal processor detects and analyzes the phase difference between the emitted light and the received light. For example, when the tray moves forward by 20 cm, the signal processor converts the phase difference into the corresponding distance change value according to the pre-set algorithm, that is, it determines that the tray has moved by 20 cm. The signal processor sends the calculated moving distance data to the control center through communication modules such as serial communication and Ethernet communication. After receiving the data, the control center can control subsequent cutting and other operations accordingly based on this information.

[0045] Furthermore, the circular saw 216 is also a conventional technical field in the prior art, and its core is a high-speed rotating circular saw blade. The motor drives the saw blade to rotate at high speed. When the sharp teeth on the saw blade contact the bridge frame, they cut into the material by relying on the powerful kinetic energy generated by the high-speed rotation, and rely on the continuous cutting action of the saw teeth on the material to achieve cutting of the side wall of the bridge frame.

[0046] See also Figure 4 The adjustment component 3 includes a plurality of circular holes 31 at the front end of the lifting seat 215, and the inner surface of the circular hole 31 located in the middle of the lifting seat 215 is rotatably connected with a bolt 32, and the outer surface of the connecting shaft 212 is provided with a thread groove 33, and the outer surface of the bolt 32 is threadedly connected with the thread groove 33.

[0047] Furthermore, the bolts 32 are placed in the circular holes 31 at different heights and connected to the thread grooves 33 in order to adjust the height of the reciprocating lifting of the lifting seat 215, thereby controlling the cutting depth of the bridge frame by the circular saw 216.

[0048] Then, the hydraulic device 12 is started first to drive the push plate 13 to push the cable bridge to move. When the laser distance sensor 217 determines that the bridge has reached the specified position, the hydraulic device 12 is turned off, and the motor 24 and the circular saw 216 are started. The motor 24 can drive the rotating arm 25 and the limit block 251 to rotate. During the rotation process, the limit block 251 will drive the swing arm 27 and the fan-shaped tooth 28 to swing back and forth synchronously, so that the gear 29 rotates back and forth, and further the gear 29 drives the rotating shaft 1 210, the connecting shaft 1 211, the connecting shaft 212 and the limit block 213 to swing left and right. During the swinging process, the limit block 213 slides in the U-shaped groove 222.

[0049] After the bolt 32 is passed through any of the circular holes 31 and the bolt 32 is threadedly connected with the thread groove 33, the connecting shaft 1 211 and the connecting shaft 212 can drive the lifting seat 215 to slide up and down in the sliding block 214 when they rotate back and forth. Synchronously, the sliding block 214 also slides back and forth in the sliding groove 221 along with the lifting seat 215, so that the lifting seat 215 can be stably lifted and lowered during the swinging process.

[0050] The circular saw 216 can follow the lifting seat 215 to vertically cut the vertical side walls on both sides of the cable tray.

[0051] See also Figure 5-6 The alternating swing component 4 includes a limit seat 41 fixedly connected to both sides of the rear end of the fixed seat 23, the inner surfaces of the two limit seats 41 are slidably connected with a sliding rod 42, the ends of the two sliding rods 42 close to each other are in contact with the lower end of the outer surface of the swing arm 27, the ends of the two sliding rods 42 away from each other are rotatably connected with a movable plate 43, the ends of the two support seats 21 away from each other are rotatably connected with a limit seat 24, and the inner surfaces of the two limit seats 44 are rotatably connected with the two movable plates 43 respectively.

[0052] Furthermore, the swing arm 27 will alternately contact the two sliding rods 42 during the swinging process, pushing the sliding rod 42 to move outward, thereby pushing the movable plate 43 to flip the angle, wherein the limit seat 44 can limit the movable plate 43, so that the movable plate 43 rotates with the limit seat 44 as the axis.

[0053] The lower end of the workbench 1 is fixedly connected to two limit seats 3 45, the inner surfaces of the two limit seats 3 45 are slidably connected to sliding rods 2 46, the ends of the two sliding rods 2 46 that are away from each other are fixedly connected to fixed plates 47, the sides of the two fixed plates 47 that are away from each other are respectively in contact with the lower ends of the movable plates 43 on the same side, the ends of the two sliding rods 2 46 that are close to each other are fixedly connected to connecting blocks 48, the ends of the two connecting blocks 48 that are away from each other are fixedly connected to springs 49, and the ends of the two springs 49 that are away from each other are respectively fixedly connected to the two limit seats 3 45.

[0054] Furthermore, the spring 49 can drive the connecting block 48 to reset and wait for the next impact of the movable plate 43 .

[0055] Furthermore, when the swing arm 27 swings left and right, it will alternately hit the sliding rods 42 on both sides. When the sliding rod 42 on the left is hit, it will drive the movable plate 43 to tilt outward, so that the lower end of the movable plate 43 hits the fixed plate 47, so that the fixed plate 47 pushes the sliding rod 46 and the connecting block 48 to move toward the middle. In this state, the sliding rod 42 on the right is in the initial state and remains motionless under the pull of the sliding rod 46. When the swing arm 27 hits the right sliding rod 42, the sliding rod 42 on the left will also return to the initial state, so that the two connecting blocks 48 move alternately toward the middle.

[0056] See also Figure 6-7 The scratching assembly 5 includes a support frame 2 51 fixedly connected to the lower end of the workbench 1, the inner surface of the support frame 2 51 is fixedly connected to a limit rod 1 52, the outer surface of the limit rod 1 52 is slidably connected to two limit blocks 3 53, the upper ends of the two limit blocks 3 53 are fixedly connected to an adjusting block 54, the rear ends of the two adjusting blocks 54 are respectively fixedly connected to the connecting blocks 48 on the same side, the inner surfaces of the two adjusting blocks 54 are rotatably connected to threaded columns 55, the outer surfaces of the two threaded columns 55 are threadedly connected to threaded sleeves 56, the rear ends of the two threaded sleeves 56 are slidably connected to a limit column 1 57, the two ends of the two limit columns 1 57 are respectively fixedly connected to the two adjusting blocks 54, the upper ends of the two threaded sleeves 56 are fixedly connected to diamond tools 58, the outer surfaces of the two diamond tools 58 are respectively slidably connected to the outer surfaces of the two adjusting blocks 54, the upper ends of the two diamond tools 58 are commonly slidably connected to the through groove 11, and the upper ends of the two threaded columns 55 are fixedly connected to handles 59.

[0057] Among them, diamond is one of the hardest substances in nature, far exceeding the common metal materials of cable bridges. When the diamond tool 58 contacts the bottom of the cable bridge under pressure, its sharp edge will embed into the surface of the bridge material. As the tool moves, the edge continues to squeeze and cut the material at the bottom of the bridge, overcoming the internal bonding force of the material with the advantage of high hardness, gradually separating the material, and thus leaving a mark.

[0058] Furthermore, when the two connecting blocks 48 move alternately toward the middle, the two diamond cutters 58 can be synchronously driven to move alternately toward the middle, so that the diamond cutter 58 makes a mark on the bottom of the cable tray, and the mark clearly marks the bending position to ensure that the bending is performed along the predetermined path; for example, when making a cable tray elbow, the depth of the mark is usually 1 / 3 to 1 / 2 of the material thickness, forming a "hinge effect", that is, using the uncut part as a fulcrum, making the bending more accurate and keeping the bottom surface continuous, thereby enhancing the stability of the connection;

[0059] At the same time, rotating the handle 59 can rotate the threaded column 55, thereby driving the threaded sleeve 56 and the diamond tool 58 to move up and down as a whole, thereby controlling the depth of the scratch made by the diamond tool 58 on the bottom of the cable bridge.

[0061] Furthermore, the principles of the circular saw 2 75 and the laser ranging sensor 2 77 are the same as those of the circular saw 1 216 and the laser ranging sensor 1 217, and all belong to the conventional technical field in the prior art. The circular saw 2 75 is arranged at an angle to facilitate cutting an oblique angle on the side wall of the bridge frame.

[0062] Furthermore, when the two side walls and the bottom surface of the cable bridge are cut, the hydraulic device 12 and the push plate 13 can be controlled to push the cable bridge straight to the next process, and the laser distance sensor 2 77 is used to measure the distance of the position where the side wall of the cable bridge needs to be beveled, and then the circular saw 2 75 is started to cut the side wall of the bridge, ensuring that the trajectory of the circular saw 2 75 during bevel cutting cooperates with the incision of the vertical part of the side wall of the bridge to form a triangle. After the cable bridge completes all the cutting processes as a whole, it becomes the appearance of the bridge 8 after cutting, refer to the attached Fig.12 , subsequently you only need to push the scratched part upwards to bend it, and then proceed with other processing.

[0063] Therefore, in this scheme, the swing cutting component 2 drives the circular saw 216 and the alternating swing component 4 to work simultaneously. The circular saw 216 follows the lifting seat 215 to cut the vertical lines of the triangles on the two side walls of the bridge frame during reciprocating swing. The alternating swing component 4 drives the scratching component 5 to synchronously scratch the bottom surface of the bridge frame, and controls the scratching depth by adjusting the height of the diamond tool 58. The whole can smoothly complete the synchronization of multiple actions such as cutting the side walls of the bridge frame and scratching the bottom, greatly shortening the time required for a single cutting and improving the overall cutting efficiency.

[0064] Embodiment 3: This embodiment is based on embodiments 1 and 2, in order to achieve the effect of ensuring that the cable tray can maintain a straight line when moving and can also maintain stability when cutting.

[0065] See also Figure 8-10 The limiting assembly 6 includes a limiting seat 4 61 fixedly connected to the upper end of the fixed seat 1 23, the outer surface of the limiting seat 4 61 is slidably connected with a mounting block 62, the upper end of the mounting block 62 is fixedly installed with a hydraulic device 2 63, both ends of the hydraulic device 2 63 are rotatably connected with a connecting rod 1 64, the sides of the two support seats 21 close to each other are rotatably connected to the limiting seat 5 65, the middle and lower sides of the two connecting rods 1 64 are respectively rotatably connected to the limiting seat 5 65 on the same side, the lower ends of the two connecting rods 1 64 are rotatably connected with a connecting rod 2 66, the ends of the two connecting rods 2 66 close to each other are rotatably connected with a clamping block 67, the ends of the two clamping blocks 67 close to each other are provided with a roller 671, the ends of the two clamping blocks 67 away from each other are fixedly connected with a telescopic rod 68, and the ends of the two telescopic rods 68 away from each other are respectively fixedly connected to the support seat 21 on the same side.

[0066] Specifically, because the hydraulic device 2 63 is located on the mounting block 62 and has no other structural limitations, when the hydraulic device 2 63 is started to push the object, it will also generate a reaction force of equal magnitude and opposite direction, which will cause the hydraulic device 2 63 to move in the opposite direction.

[0067] The roller 671 can move the cable tray when limiting the cable tray, so that it can maintain a straight line during the movement;

[0068] The telescopic rod 68 can limit the clamping block 67 to keep it moving in parallel, thereby limiting the two sides of the cable tray.

[0069] The two connecting rods 64 are fixedly connected to an L-shaped connecting rod 69 on one side close to each other, and the two L-shaped connecting rods 69 are rotatably connected to a sliding column 611 at one end close to each other. The lower end of the sliding column 611 is fixedly connected to a pressure plate 612, and the lower end of the fixed seat 23 is fixedly connected to a limiting column 2 613, and the outer surface of the limiting column 2 613 is slidably connected to the sliding column 611.

[0070] Furthermore, the second limiting column 613 can limit the sliding column 611 and the pressing plate 612 to enable them to run stably vertically.

[0071] Furthermore, before the hydraulic device 12 drives the push plate 13 to push the cable tray to move, the hydraulic device 2 63 is started first. When the hydraulic device 2 63 pushes the connecting rod 1 64 on one side, a reaction force of equal magnitude and opposite direction is generated, so that the hydraulic device 2 63 moves toward the other side together with the mounting block 62, and then a thrust is generated on the connecting rods 1 64 on both sides simultaneously, so that the two connecting rods 1 64 swing around the limit seat 5 65 as the axis, and the lower ends of the two connecting rods 1 64 approach the middle synchronously, thereby driving the two connecting rods 2 66 to synchronously push the clamping block 67 and the roller 671 toward the end close to each other, and limit the two sides of the cable tray, so that the cable tray remains straight in the process of being pushed by the hydraulic device 12 and the push plate 13;

[0072] When the cable tray needs to be cut, the hydraulic device 2 63 is controlled again to retract it, and then a pulling force is generated on the connecting rods 1 64 on both sides, so that the two connecting rods 1 64 swing around the limit seat 5 65 as the axis, and the lower ends of the two connecting rods 1 64 open outward synchronously. During the opening process, the upper parts of the two connecting rods 1 64 will tilt toward the middle, thereby driving the L-shaped connecting rod 69 to squeeze the sliding column 611 and the pressure plate 612 downward, so that the pressure plate 612 can press and limit the cable tray to keep it stable when being cut.

[0073] Therefore, the present scheme can achieve a dual effect by pushing and pulling the connecting rod 1 64 through the hydraulic device 2 63. Pushing the connecting rod 1 64 can allow the clamping block 67 to accurately limit the two sides of the cable tray before cutting, and keep the cable tray straight during the displacement process to avoid tilting. Pulling the connecting rod 1 64 can control the pressure plate 612 to press down, limit the cable tray in the cutting state, prevent the tray from moving, effectively avoid shaking and displacement during the cutting process, ensure the stability and accuracy of the cutting, and reduce the scrap rate.
