[0002] Cable tray is a product derived for the protection of cables. It is a protective shell for cables to prevent them from being damaged by external factors. Cable trays are composed of trough-type, tray-type or ladder-type straight sections, elbows, tees, four-way components, and support arms (arm-type brackets), hangers, etc. A rigid structural system with close support for cables is called cable tray (referred to as cable tray); cable trays are divided into trough-type, tray-type, ladder-type, grid-type and other structures, and are composed of brackets, support arms and installation accessories.

[0003] The utility model patent with publication number CN220388128U discloses a grooving device for cable tray processing. The connecting pipe absorbs the exhaust gas in a circular movable manner, so that the absorption range is larger and the effect is better. The baffle is arc-shaped, and the length of the baffle is greater than the length of the internal groove of the connecting plate. In this way, when the connecting pipe moves in the internal groove of the connecting plate, the baffle can prevent the exhaust gas from leaking from the internal groove of the connecting plate.

[0021] 1. In the present invention, the cable tray is transported to the upper surface of the processing seat in a U shape and then comes to rest. First, the longitudinal synchronous cylinder is used to align the longitudinal angle of the cable tray to ensure that the cable tray is parallel to the inner wall surface of the positioning recess. The two sliding members simultaneously approach the middle of the processing seat. Under the friction between the slide table and the inclined surface of the docking table, the end of the lifting strip in the sliding member always slides along the limiting groove, moves upward during the sliding and leaves the inside of the limiting groove. The limit frame increases its vertical height under horizontal sliding until it rises to the top surface of the docking table, and the lifting strip stops increasing its vertical lifting height until the top side surfaces of the two lifting strips respectively contact the two end portions of the two side surfaces of the cable tray in the positioning recess, thereby fixing the two side ends of the cable tray, avoiding the shaking of the cable tray, increasing the accuracy of the cable tray slotting, and adapting to the fixing of cable trays of different heights and widths.

[0022] 2. When sliding and fitting, the width of the docking platform is the same as that of the sliding platform, so that the docking platform enters the alignment groove, which is convenient for lifting the lifting strip. Since a gap is reserved between the docking platform and the inner wall of the accommodating cavity, it is convenient for the limit frame to slide, avoiding movement interference between the docking platform and the limit frame, and realizing lifting and lowering while moving horizontally;

[0023] 3. The bottom surface of the cable tray is grooved by a slotting tool, and the linear guide slides to adapt to the slotting at different positions on the cable tray. There is no need to move the cable tray again. It is fixed once. After the slotting tool passes through the slotting hole, the waste material after slotting falls into the blanking cavity and reaches the position of the discharge port along the slope of the triangular ramp. After that, it is collected by the material box through the through slot, which is convenient for repeated recycling of the waste material. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0033] See also Figure 1-Figure 6As shown, the grooving equipment for cable tray processing comprises an operating table 1, a processing seat 4 is installed in the middle of the top surface of the operating table 1, the upper surface of the processing seat 4 is provided with a positioning recess 18 for the entry of the cable tray, and the upper surface end of the positioning recess 18 is provided with a sensing unit for detecting the cable tray, and transmission units for auxiliary transmission of the cable tray are provided on both sides of the positioning recess 18, two of which are driven by synchronous cylinders, and the driving direction is longitudinal. A clamping component for fixing the end portions of the two side edges of the cable tray is installed inside the processing seat 4, and a grooving component for processing the cable tray fixed on the side is installed above the processing seat 4. The clamping component comprises two sliding members slidably installed inside the processing seat 4 and a docking table 8 used in conjunction with the sliding members, and a lifting strip 11 moving in the vertical direction is movably installed inside each sliding member, and the lifting strip 11 is in contact with the side of the cable tray. Initially, the clamping component is hidden inside the processing seat 4, that is, the lifting strip 11 is hidden. The cable tray is hidden in the limiting groove 6 to facilitate the transportation and passage of the cable tray. The cable tray is input into the positioning recess 18 on the processing seat 4 in a U shape. The cable tray is detected by the sensing unit at the end. Then the transfer unit 5 stops transporting the cable tray, so that the cable tray stays in the processing seat 4. At this time, the positioning component starts to work, and the two sliding members approach the middle of the processing seat 4 at the same time, and the sliding member and the docking table 8 are in sliding contact. Under the friction action of the inclined surface of the docking table 8, the end of the lifting strip 11 in the sliding member always slides along the limiting groove 6, and moves upward during sliding to leave the inside of the limiting groove 6 until the top side surfaces of the two lifting strips 11 respectively abut against the two end portions of the two side surfaces of the cable tray in the positioning recess 18, thereby fixing the two side ends of the cable tray, avoiding shaking of the cable tray, and increasing the accuracy of the cable tray grooving. After the grooving is completed, the positioning component is closed, and the cable tray is assisted in conveying through the transmission unit on the side, with a high degree of automation.

[0034] See also Figure 2 and Figure 3 As shown, the sliding member includes a limit frame 10 with a hollow structure, and a lifting strip 11 passing through the top surface of the limit frame 10 is movably installed on the top of the inner cavity of the limit frame 10, and an elastic member 13 of a rectangular structure is sleeved on the bottom upper surface of the lifting strip 11, and one end of the elastic member 13 is fixed to the top inner wall of the limit frame 10; both sides of the limit frame 10 are penetrated by a positioning groove 14, and the bottom surface of the lifting strip 11 is fixedly connected to the plug plate 12, and a fixed protrusion 15 that slides and fits with the positioning groove 14 is installed on the bottom side of the plug plate 12, and a slide table 17 is installed on the bottom surface of the plug plate 12, and the bottom surface of the slide table 17 is in contact with the inclined surface of the docking table 8;

[0035] In the initial state, the bottom surface of the slide 17 is in contact with the bottom surface of the accommodating cavity 7, and the elastic member 13 is in a free state, that is, it maintains its original length. The sliding of the slide member drives the sliding friction between the slide 17 and the docking table 8, so that the slide 17 drives the fixed protrusion 15 to slide upward along the alignment groove 14, and then drives the plug board 12 and the lifting strip 11 to move upward. At this time, the elastic member 13 is squeezed and elastically deformed, and the upper part of the lifting strip 11 slides horizontally along the limiting groove 6 on the one hand, and leaves the inside of the limiting groove 6, until the side surface of the lifting strip 11 is in contact with the two ends of the two sides of the cable tray, so as to fix the two side ends of the cable tray;

[0036] When the sliding member moves away from one side of the docking platform 8 , the elastic member 13 recovers its elastic deformation, and the sliding member recovers to its initial shape.

[0037] See also Figure 1 and Figure 2 As shown, the upper surface of the processing seat 4 is provided with a limiting groove 6 for accommodating the entry of the lifting strip 11, and there are four limiting grooves 6 in total. The interior of the processing seat 4 is provided with a accommodating chamber 7, and the interior of the accommodating chamber 7 is rotated by a dual-axis motor and is equipped with a bidirectional lead screw 9, which is threadedly connected to one side of a limit frame 10. The accommodating chamber 7 is communicated with the two limiting grooves 6, and a fixed slider 16 is installed on the surface of the side of the limit frame 10 away from the bidirectional lead screw 9 and is arranged to fit the track surface of the accommodating chamber 7. Initially, the lifting strip 11 is located inside the limiting groove 6 and is not higher than the upper surface height of the limiting groove 6. In the driving state, by The spiral rotation of the bidirectional lead screw 9 drives the limit frame 10 to move horizontally, driving the fixed slider 16 to slide in the track surface on the accommodating chamber 7, realizing the horizontal sliding of the limit frame 10, driving the slide 17 to contact the docking table 8, at this time the slide 17 drives the plug plate 12 to rise, and the lifting strip 11 on the top of the plug plate 12 passes through the interior of the limiting groove 6 and slides in the limiting groove 6, and is exposed to the positioning recess 18. The vertical height of the limit frame 10 increases under horizontal sliding, until it is raised to the top surface of the docking table 8, and the lifting strip 11 stops increasing the height, which is suitable for the fixation of cable trays of different heights and widths.

[0038] See also Figure 2 As shown, the docking platform 8 is arranged on the bottom surface of the inner cavity of the accommodating cavity 7 and there is a gap between the inner wall surfaces of the two accommodating cavities 7, and the width of the docking platform 8 is the same as the width of the slide 17, so that the docking platform 8 enters the alignment groove 14. Since the gap is reserved between the docking platform 8 and the inner wall of the accommodating cavity 7, the sliding of the limit frame 10 is facilitated, and the movement interference between the docking platform 8 and the limit frame 10 is avoided, and the lifting and lowering are realized while the horizontal movement is carried out.

[0039] See also Figure 1 and Figure 6As shown, the slotting assembly includes a fixed horizontal frame arranged above the processing seat 4 and having a U-shaped structure, a linear guide rail 22 is installed on the top bottom surface of the fixed horizontal frame, a mounting frame 23 is installed on the sliding seat outside the linear guide rail 22, a cylinder 24 is fixed in the middle of the bottom surface of the mounting frame 23, a guide pressure plate 25 is connected to the pushing end of the cylinder 24, a slotting tool 29 for slotting the cable tray is arranged in the middle of the bottom surface of the guide pressure plate 25, and a slot for the slotting tool 29 to vertically enter is arranged in the middle of the top surface of the processing seat 4 Hole position 19, slotting hole position 19 is arranged in multiple rows, and each row is arranged with multiple holes. After the cable tray is fixed, the cylinder 24 pushes the guide pressure plate 25 downward. At this time, the slotting tool 29 directly acts on the lower surface of the cable tray and enters into the slotting hole position 19 to slot the cable tray. After this slotting, the slotting tool 29 is reset to the initial height. As the slide seat slides on the linear guide rail 22, the slotting tool 29 is driven to reach another slotting position of the cable tray to realize slotting at different positions.

[0040] See also Figure 6 As shown, a transverse rail groove 26 is provided on the inner wall surface of the fixed cross frame, and a plurality of vertical rail grooves 27 are connected on the bottom surface of the transverse rail groove 26. A fixed block 28 that slides with the transverse rail groove 26 and the vertical rail groove 27 is installed on the end surface of the guide pressure plate 25; when the linear guide 22 drives the slotting tool 29 connected to the slide seat to slide horizontally, the fixed block 28 slides horizontally in the transverse rail groove 26 to a position connected to the vertical rail groove 27, and the cylinder 24 pushes the fixed block 28 to slide in the vertical rail groove 27, providing guidance for the movement of the guide pressure plate 25.

[0041] See also Figure 5 As shown, the interior of the processing seat 4 is provided with a blanking cavity 20 which is communicated with the slotted hole 19, and a triangular inclined platform 30 is provided at the bottom end of the inner cavity of the blanking cavity 20. Both bottom ends of the triangular inclined platform 30 are provided with discharge ports 21. The surface of the operating table 1 is penetrated by a through groove 3 which is communicated with the discharge port 21, and a material box 2 for collecting slotted waste is installed under the operating table 1. When slotting, the bottom surface of the cable tray is slotted by a slotting tool 29. After the slotting tool 29 passes through the slotted hole 19, the slotted waste falls into the blanking cavity 20 and reaches the position of the discharge port 21 along the slope surface of the triangular inclined platform 30. Thereafter, it is collected by the material box 2 through the through groove 3, which is convenient for repeated recycling of the waste.

[0042] See also Figure 1 As shown, transfer units 5 for conveying and outputting the cable tray are provided on both sides of the processing seat 4, and the transfer units 5 include a plurality of roller rods, and the outer surface of the roller rods is flush with the upper surface of the positioning recess 18. The transfer units 5 are used for conveying and outputting functions, thereby improving the conveying efficiency.

[0043] A method for using a slotting device for bridge processing, the method comprising the following steps:

[0044] Step 1: The cable tray is transported to the upper surface of the processing seat 4 by the transfer unit 5. After the cable tray is detected by the sensing unit at the end, the transfer unit 5 stops transporting the cable tray, and the sliding member slides toward the docking station 8 by rotating the two bidirectional lead screws 9;

[0045] Step 2: The slide 17 contacts the inclined surface of the docking platform 8, and the slide 17 generates an upward thrust and drives the plug plate 12 and the lifting strip 11 to slide vertically upward, thereby elastically squeezing the elastic member 13. The top end of the lifting strip 11 is exposed and raised, and slides horizontally inside the limiting groove 6 until it abuts against the side end of the cable tray to achieve fixation;

[0046] Step three, change the horizontal slotting position of the slotting tool 29 through the linear guide rail 22. During slotting, the end of the slotting tool 29 enters the slotting hole 19 so that the slotted waste enters the blanking cavity 20, and slides down the two inclined surfaces of the triangular ramp 30 and enters the material box 2 through the discharge port 21 and the through slot 3 in turn.

[0047] When the present invention is in use, the cable tray is transported to the upper surface of the processing seat 4 in a U shape. First, the longitudinal synchronous cylinder is used to align the longitudinal angle of the cable tray to ensure that the cable tray is parallel to the inner wall surface of the positioning recess 18. The two sliding members simultaneously approach the middle of the processing seat 4, and the sliding member and the docking table 8 are in sliding contact. Under the friction effect of the inclined surface of the docking table 8, the end of the lifting strip 11 in the sliding member always slides along the limiting groove 6, and moves upward during the sliding to leave the inside of the limiting groove 6, until the top side surfaces of the two lifting strips 11 respectively contact the two end portions of the two side surfaces of the cable tray in the positioning recess 18, so as to fix the two side ends of the cable tray, avoid the shaking of the cable tray, and increase the accuracy of the cable tray grooving. The vertical height of the limit frame 10 increases under horizontal sliding until it is raised to the top surface of the docking table 8, and the lifting strip 11 stops the increase in vertical lifting height, which is suitable for the fixing of cable trays of different heights and widths.

[0048] During sliding fit, the width of the docking platform 8 is the same as that of the sliding platform 17, so that the docking platform 8 enters the alignment groove 14, which facilitates the lifting of the lifting strip 11. Since a gap is reserved between the docking platform 8 and the inner wall of the accommodating cavity 7, it is convenient for the limiting frame 10 to slide, avoiding motion interference between the docking platform 8 and the limiting frame 10, and achieving lifting and lowering while horizontally moving;

[0049] The bottom surface of the cable tray is slotted by the slotting tool 29. After the slotting tool 29 passes through the slotting hole 19, the slotted waste falls into the blanking cavity 20 and reaches the position of the discharge port 21 along the slope surface of the triangular ramp 30. Then, the waste is collected by the material box 2 through the through slot 3, so as to facilitate the repeated recycling of the waste.

[0050] After the slotting, the clamping assembly releases the fixation of the two side ends of the cable tray, and the transmission unit assists in transporting the cable tray, and the cable tray is output by the transfer unit 5.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.

The method for using the slotting equipment for bridge processing according to claim 5, characterized in that: The method of use includes the following steps: Step 1: The cable tray is transported to the upper surface of the processing seat (4) by the transfer unit (5), and after the cable tray is detected by the sensing unit at the end, the transfer unit (5) stops transporting the cable tray, and the sliding member slides toward the docking platform (8) by rotating two bidirectional lead screws (9); Step 2: The slide (17) is in contact with the inclined surface of the docking platform (8), so that the slide (17) generates an upward thrust and drives the plug plate (12) and the lifting strip (11) to slide vertically upward, thereby generating elastic compression on the elastic member (13). The top end of the lifting strip (11) is exposed and raised, and slides horizontally inside the limiting groove (6) until it abuts against the side end of the cable tray, thereby achieving fixation; Step 3: The horizontal slotting position of the slotting tool (29) is changed by the linear guide rail (22). When slotting, the end of the slotting tool (29) enters the slotting hole (19) so that the slotted waste enters the blanking cavity (20), slides down along the two inclined surfaces of the triangular ramp (30), and enters the material box (2) through the discharge port (21) and the through slot (3) in sequence.
