[0002] Cable trays come in trough, tray, ladder, and grid configurations, and are composed of brackets, supports, and mounting accessories. Cable trays can be installed independently within buildings or attached to various structures and pipe gallery supports. They should feature simple structure, attractive design, flexible configuration, and easy maintenance. All components must be galvanized for installation outside buildings.

[0003] During the production process, cable trays often need to go through multiple processes, such as welding, grinding, cutting and spraying. In order to facilitate the production, conveying equipment is needed to transport the cable trays during the production process to facilitate their transfer between various processes and facilitate production.

[0004] At present, the existing technology often requires double-sided processing when processing cable trays. For example, double-sided spraying is required when spraying cable trays. During the spraying process of the existing technology, in order to avoid the clamping position of the conveying equipment clamp during feeding, a second spraying is often required. For example, the inner wall of the cable tray is sprayed during the first spraying. After the first spraying is completed, the cable tray needs to be manually removed, and then the clamp is clamped inside the cable tray for a second spraying. Such processing is time-consuming and labor-intensive, inefficient, and is not conducive to production.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] like Figures 1 to 4 As shown, a cable tray processing feeding and conveying device according to an embodiment of the present invention includes a conveying frame 1, a pair of screw rods 2 are installed on the upper part of the conveying frame 1, and a clamp mounting frame 3 is connected to the outside of the screw rod 2 by a thread, and a pair of liftable clamping rods 4 are slidably connected on both sides of the clamp mounting frame 3, and the sides of the pair of clamping rods 4 close to each other are rotatably connected to a rotating gear 5, and the side of the rotating gear 5 away from the clamping rod 4 is fixedly connected to an electric telescopic rod, and the output end of the electric telescopic rod is fixedly connected to a sponge suction cup 6, and an adjusting tooth plate 7 is fixedly connected to the bottom surface of the inner wall of the conveying frame 1 and at a position corresponding to the sponge suction cup 6;

[0034] During operation, the processing and conveying device of the cable tray 30 in the prior art often does not have a flipping function, which leads to certain disadvantages in the processing and conveying of the cable tray 30. However, according to the embodiment of the present invention, the cable tray 30 is first installed between a pair of sponge suction cups 6, and then the electric telescopic rod is started to operate so that the sponge suction cups 6 are attached to the outer surface of the cable tray 30, and then the sponge suction cups 6 are started to adsorb the cable tray 30, thereby further improving the clamping effect of the cable tray 30. It should be noted that a servo motor assembly is installed on the outside of the conveying frame 1 to drive a pair of screw rods 2 to rotate synchronously. This part is a prior art and will not be described in detail in the embodiment of the present invention. After the clamping is completed, the servo motor assembly is started to drive the screw rod 2 to rotate, and the rotation of the screw rod 2 drives the clamp mounting frame 3 to slide, and the clamp The mounting frame 3 slides, thereby driving the clamping rod 4 to move, thereby driving the cable tray 30 to move; when one side of the cable tray 30 is processed, the other side needs to be processed. At this time, an adjusting tooth plate 7 is designed at the bottom end of the conveying frame 1. When the clamping rod 4 drives the rotating gear 5 to rotate through the adjusting tooth plate 7, the rotating gear 5 will engage with the adjusting tooth plate 7. It should be noted that the length of the adjusting tooth plate 7 is half the circumference of the rotating gear 5. Therefore, the rotating gear 5 at this time will rotate half a circle under the action of the adjusting tooth plate 7. During the rotation, the rotating gear 5 will synchronously drive the sponge suction cup 6 to rotate. The rotation of the sponge suction cup 6 drives the cable tray 30 to rotate. The cable tray 30 rotates half a circle to complete the flipping, thereby facilitating the processing of the cable tray 30, enriching the functional diversity of the conveying equipment, and facilitating the processing operation.

[0035] like Figures 1 to 3 As shown, the bottom end of the conveying frame 1 is fixedly connected to an equipment mounting frame 8, and a rotating slot 9 is provided inside the equipment mounting frame 8 at a position corresponding to the adjusting tooth plate 7;

[0036] During operation, in actual use, corresponding processing tools can be installed on the equipment mounting frame 8 according to specific processing requirements. It should be noted that two sets of processing tools need to be installed to facilitate the multi-stage processing before and after the rotation of the cable tray 30. At the same time, the design of the rotating groove 9 can provide sufficient rotation space for the cable tray 30.

[0037] like Figures 1 to 7 As shown, a pair of inner support plates 10 are provided inside the clamp mounting frame 3, the top ends of the inner support plates 10 are fixedly connected to a connecting rod 11, the top ends of the connecting rod 11 are fixedly connected to a guide rod 13, and the top ends of the guide rod 13 are provided with a pushing assembly, which is used to push the guide rod 13 to drive the pair of inner support plates 10 to descend and move away from each other;

[0038] During operation, after the rotation operation is completed, in order to facilitate the processing of the outer surface of the cable tray 30, for example, when performing spraying processing, the sponge suction cup 6 needs to be separated from the cable tray 30, so that the cable tray 30 can be fully sprayed; after the rotation of the cable tray 30 is completed, the pushing component pushes the guide rod 13 to move downward and away from each other, and the movement of the guide rod 13 drives the connecting rod 11 to move, and the movement of the connecting rod 11 drives the inner support plate 10 to move downward and away from each other. In the process of the downward movement of the inner support plate 10, it will first extend into the interior of the cable tray 30, and then continue to move downward and away from each other until the inner support plate 10 and the cable tray are aligned. The inner wall of the cable tray 30 is fitted and squeezed, so that the cable tray 30 can be clamped and limited by the squeezing force, and then the clamping rod 4 moves upward to drive the sponge suction cup 6 away from the surface of the cable tray 30, leaving enough space for the processing of the cable tray 30, thereby achieving the effect of automatically switching the clamp, providing a basis for the comprehensive processing of the cable tray 30, and improving the applicability of the equipment; it should be noted that in actual use, the corresponding movement trajectory of the inner support plate 10 needs to be designed according to the size of the cable tray 30 to avoid the inner support plate 10 moving beyond the inner wall range of the cable tray 30 when it has not extended into the interior of the cable tray 30.

[0039] like Figures 5 to 8 As shown, the pushing assembly includes an angled block 14 fixed to the top of the guide rod 13, and also includes a sliding limit plate 16;

[0040] The sliding limit plate 16 includes a horizontal guide portion 1601 and a descending guide portion 1602. The bottom surfaces of both sides of the descending guide portion 1602 are provided with guide bevels 1603. The top surface of the bevel block 14 has an inclination angle that matches the guide bevels 1603.

[0041] During operation, in actual use, when the clamp mounting bracket 3 moves, it will simultaneously drive the guide rod 13 to move, and the movement of the guide rod 13 will drive the bevel block 14 to move. When the cable tray 30 completes its rotation, the bevel block 14 just contacts the sliding limit plate 16. Since the guide bevel angle 1603 is adapted to the inclination angle of the bevel block 14, after the bevel block 14 contacts the sliding limit plate 16, under the continuous movement of the guide rod 13, the bevel block 14 will gradually slide along the direction of the guide bevel angle 1603. During the sliding process, the bevel blocks 14 will gradually descend and move away from each other, thereby driving the inner support plate 10 to descend and move away from each other, until the inner support plate 10 is in contact with the inner wall of the cable tray 30 and clamps it. When the bevel block 14 moves to the position of the horizontal guide portion 1601, the inner support plate 10 just completes the clamping of the cable tray 30, and then the bevel block 14 moves along the horizontal guide portion 1601 to drive the inner support plate 10 to maintain the clamping posture, and in this posture, the cable tray 30 is rotated and processed.

[0042] like Figures 6 to 8 As shown, the bottom end of the guide rod 13 is connected through the limit block 12, and the limit block 12 is externally slidably connected to a pair of limit frames 17, and the pair of limit frames 17 are fixedly connected to the fixture mounting frame 3;

[0043] During operation, by designing the limit block 12 and the limit frame 17, as the guide rod 13 descends and moves away from each other, the guide rod 13 slides inside the limit block 12 and pushes the limit block 12 to slide in the limit frame 17, thereby limiting it and improving the stability of the equipment operation.

[0044] like Figures 6 to 8 As shown, a return spring 15 is fixedly connected between the guide rod 13 and the limit block 12, and a multi-stage telescopic rod 18 and a sliding spring 19 are fixedly connected between the limit block 12 and the fixture mounting frame 3. The sliding spring 19 is sleeved on the outside of the multi-stage telescopic rod 18;

[0045] During operation, as the guide rod 13 descends, it compresses the return spring 15 at the same time. As the guide rod 13 pushes the limit block 12 to slide, the limit block 12 compresses the sliding spring 19 to drive the multi-stage telescopic rod 18 to contract. The design of the return spring 15 and the sliding spring 19 serves to buffer the movement of the guide rod 13, improve its operating stability, and also provide power for the subsequent reset of the guide rod 13.

[0046] like Figures 6 to 8 As shown, a pair of connecting rods 11 are provided with a push plate 20 on the side away from each other, and a piston rod 21 is fixedly connected to the side of the push plate 20 away from the connecting rod 11. A piston is fixedly connected to the end of the piston rod 21 away from the push plate 20, and a piston cylinder 22 is slidably connected to the outside of the piston. The piston cylinder 22 is fixed to the bottom surface of the clamp mounting frame 3, and the piston cylinder 22 is connected to the inner support plate 10 through a hose.

[0047] During operation, when the guide rod 13 pushes the limit block 12 to slide, it will simultaneously push the push plate 20 to move. The movement of the push plate 20 drives the piston rod 21 to slide in the piston cylinder 22, and then squeezes the air inside the piston cylinder 22. After squeezing, the air is transmitted to the inner support plate 10 through the hose and ejected through the through holes opened on the surface of the inner support plate 10. The ejected gas blows toward the inner wall of the cable tray 30, removing the processing residue remaining on the inner wall surface of the cable tray 30, and improving the clamping effect of the cable tray 30. At the same time, during the spraying operation, the blown air flow can also accelerate the solidification of the paint film on the surface of the cable tray 30, reducing the risk of damage to the paint film during the clamping process; it can be understood that when spraying the cable tray 30, a set of paint film drying devices should be installed after the rotating station and before the clamping station of the inner support plate 10.

[0048] like Figures 6 to 8 As shown, a pressure barrel 26 is provided on one side of the pair of connecting rods 11 close to each other, and a push rod 27 is slidably connected to both sides of the pressure barrel 26. A pressure regulating assembly is installed on the top of the pressure barrel 26 to regulate the pressure inside the pressure barrel 26;

[0049] During operation, as the guide rod 13 moves downward, the pressure regulating assembly operates synchronously to pressurize the interior of the pressure barrel 26. The increase in pressure causes the push rod 27 to slide out from the interior of the pressure barrel 26 and exert a thrust on the connecting rod 11, thereby assisting the operation of the connecting rod 11 and improving the stability of the equipment operation.

[0050] like Figures 5 to 8 As shown, the pressure regulating assembly includes a hollow column 25, which is fixedly connected between a pair of limit frames 17. The hollow column 25 is connected to the pressure barrel 26 through a pipeline. A downward pressure rod 24 is slidably connected inside the hollow column 25. The bottom surface of the descending guide portion 1602 is provided with a downward pressure slide 1604 adapted to the downward pressure rod 24.

[0051] During operation, as the clamp mounting frame 3 moves, the limit frame 17 will synchronously drive the hollow column 25 to move. The hollow column 25 gradually contacts the downward pressure slide 1604 and gradually moves downward under the action of the downward pressure slide 1604. The downward movement of the hollow column 25 will squeeze the air inside the pressure barrel 26 and press the air into the interior of the pressure barrel 26, thereby achieving a pressurization effect. It should be noted that, in actual design, the speed at which the increase in pressure inside the pressure barrel 26 drives the push rod 27 to move should be consistent with the speed at which the bevel block 14 drives the guide rod 13 to move horizontally.

[0052] like Figures 2 to 4 As shown, an adjustment spring 28 is fixedly connected between the clamping rod 4 and the clamp mounting frame 3, and a lifting limit plate 29 is provided above the clamping rod 4. Both ends of the lifting limit plate 29 are fixedly connected to the conveying frame 1, and the lifting limit plate 29 is fixedly connected to the sliding limit plate 16 through a plurality of connecting rods;

[0053] The lifting limit plate 29 includes a translation plate 2901 and a lifting plate 2902;

[0054] During operation, the adjusting spring 28 is in a stretched state in the initial state. When the clamping rod 4 moves with the clamp mounting frame 3, its top end also moves along the trajectory of the lifting limit plate 29. In the initial state, the translation plate 2901 applies pressure to the adjusting spring 28 to prevent it from resetting. When the inner support plate 10 completes the clamping operation of the cable tray 30, the clamping rod 4 just moves to the end of the translation plate 2901 and gradually enters the rising plate 2902. Figure 1-Figure 3As shown, the rising plate 2902 is in an upward tilted posture, thereby gradually reducing the pressure applied to the adjusting spring 28, so that the adjusting spring 28 is reset and drives the clamping rod 4 to move upward. During this process, the sponge suction cup 6 is synchronously closed and the electric telescopic rod is synchronously contracted. Finally, the sponge suction cup 6 will move to the top of the cable tray 30, thereby leaving enough space for the processing of the cable tray 30.

[0055] It should be noted that the top ends of the clamping rod 4 and the pressing rod 24, the end of the push rod 27 close to the connecting rod 11, and the end of the push plate 20 close to the connecting rod 11 are all rotatably connected to the rotating ball 23. The design of the rotating ball 23 can reduce friction and improve the stability of the equipment operation.
