Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and specifically to a conveying device for the production of cable trays. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, cantilever arms and installation accessories, etc. The cable trays in buildings can be erected independently or laid on various building (structure) buildings and pipe gallery brackets, and should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized, and the galvanized cable trays are installed outdoors on buildings. In the patent application with the application publication number CN118164246A, it includes a frame. One end of the frame is located above the first conveyor, and the other end of the frame is located above the second conveyor. A movable frame and a side shift drive assembly for driving the movable frame to move laterally are arranged on the frame. The moving direction of the movable frame is perpendicular to the conveying directions of both the first conveyor and the second conveyor. A plurality of clamping assemblies for clamping the sheet material raw materials are arranged on the movable frame. A limiting mechanism for defining the clamping position of the sheet material raw materials is arranged at one end of the frame close to the first conveyor. A stop and positioning mechanism for stopping the laterally moving sheet material raw materials and positioning the sheet material raw materials is arranged on the frame. This application has the effect of preventing the position of the sheet material raw materials from shifting during the side shift conveying process, thereby improving the accuracy of the side shift conveying position of the sheet material raw materials.

[0003] In the above-mentioned patents or prior arts, during the production process of cable trays, in order to meet the anti-corrosion requirements and aesthetic requirements, the surface of the cable trays usually needs to be painted. During the painting transfer and conveying process, most of them adopt the method of lifting and transferring by a crane. During the painting process, the contact part between the lifting rope and the cable tray forms a physical blockage, and the paint mist cannot directly cover it, resulting in the lack or insufficient thickness of the paint film at the contact point and the surrounding area, which may affect the overall anti-corrosion performance of the cable tray and reduce its service life. In addition, the lifting rope hinders the movement trajectory of the paint mist particles, and the thickness of the paint film at the edge of the shielding area decreases in a "gradual change" manner, making the uniformity of the paint film poor and affecting the appearance quality of the cable tray. Summary of the Invention

[0004] The problem to be solved by the present invention is that the lifting rope of the existing hoisting and conveying equipment will hinder the integrity of painting during the painting process of the cable tray.

[0005] To solve the above technical problems, the technical solution of the present invention is: a conveying device for cable tray production, including a hoisting and conveying frame and a cable tray body. A hoisting conveyor is installed on the hoisting and conveying frame. One output end of the hoisting conveyor is fixedly provided with a hoisting seat through a fixing strip. An anti-sway and stabilizing component is arranged on the hoisting seat. Two sling bodies are arranged at the other output end of the hoisting conveyor. The cable tray body is arranged between the two sling bodies; The anti-sway and stabilizing component includes a plug-in cylinder slidably connected to the hoisting seat. A connecting rope is fixedly arranged at the bottom end of the hoisting seat. A plug-in seat is fixedly arranged at the bottom end of the connecting rope. A buffer plate is fixedly arranged at the bottom end of the plug-in seat. Two first buffer plates are slidably arranged inside the buffer plate. Two second buffer plates are slidably arranged inside the buffer plate. And the two sling bodies are respectively inserted between the two pairs of first buffer plates and second buffer plates. An adjusting component is arranged at the bottom of the buffer plate; The adjusting component includes two lower extension plates respectively fixed to the bottom ends of the two first buffer plates. An arc-shaped push rod is fixedly arranged on each lower extension plate. An adjusting rotating rod is rotatably arranged on the arc-shaped push rod. One end of the adjusting rotating rod is rotatably connected to an adjusting main rod. And the adjusting main rod is slidably connected to the buffer plate. An adjusting sleeve is fixedly arranged on the adjusting main rod. And the adjusting sleeve is sleeved on the outer wall of the sling body.

[0006] Preferably, two guiding rods are fixedly arranged at the top end of the plug-in cylinder. And the two guiding rods are both slidably connected to the hoisting seat. Electric push rod bodies fixedly connected to the hoisting seat are arranged on the two guiding rods. A guiding groove matching the two guiding rods is formed on the hoisting seat. The two guiding rods are symmetrically arranged with respect to the connecting rope.

[0007] Preferably, two plug-in blocks are fixedly arranged on the inner wall of the plug-in cylinder. And the two plug-in blocks are symmetrically arranged with respect to the plug-in cylinder. The plug-in cylinder is located above the plug-in seat. An opening guiding groove matching the two plug-in blocks is formed on the plug-in seat. Two hydraulic propulsion grooves are formed on the plug-in seat below the opening guiding groove.

[0008] Preferably, a pair of the first buffer plates and a pair of the second buffer plates are symmetrically arranged with respect to the buffer plate. Two moving grooves matching the pair of first buffer plates and the pair of second buffer plates are formed on the buffer plate. And the two moving grooves are symmetrically arranged with respect to the buffer plate.

[0009] Preferably, the two adjusting rotating rods are cross-arranged. Two limiting sleeves are fixedly arranged at the bottom of the buffer plate. And the two limiting sleeves are respectively slidably connected to the two adjusting main rods. Each sling body is made of nylon material.

[0010] Preferably, arc-shaped piston rods are fixedly arranged on both of the two first buffer plates and the two second buffer plates, and each arc-shaped piston rod is slidably connected to the buffer disc, and each arc-shaped piston rod is inserted into the buffer disc. Buffer springs fixedly connected to the inner wall of the buffer disc are fixedly arranged on each of the first buffer plates and the second buffer plates, and each buffer spring is sleeved on the arc-shaped outer wall of the arc-shaped piston rod. Pusher seats are slidably arranged inside the two hydraulic propulsion grooves respectively on the plugging seat. Two hydraulic grooves matching with a plurality of arc-shaped piston rods are formed inside the buffer disc, and the two hydraulic grooves are respectively communicated with the hydraulic propulsion grooves.

[0011] Preferably, two communication grooves are formed inside the buffer disc, and two ends of each communication groove are respectively communicated with the communication groove and the hydraulic propulsion groove.

[0012] Preferably, two fixed pulleys are rotatably arranged on the top of the hoisting seat, and the arc-shaped outer walls of each fixed pulley are in contact with the outer wall of the sling body.

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) By loosening the plugging cylinder and with the cooperation of the anti-swing and stabilizing assembly, the buffer disc can be in a relatively stable state. At the same time, by starting the hoisting conveyor to move the cable tray body, the cable tray body can move towards both sides at this time, and with the cooperation of the adjusting assembly, the two sling bodies can move towards both sides, so that the parts originally covered by the pressure of the original sling body on the cable tray body are exposed outside again, which is convenient for secondary painting in the later stage. After the cable tray is painted for the first time, the contact part between the sling and the tray forms a "spraying blind area" due to physical shielding. The hoisting and conveying equipment displaces the sling through the lateral thrust, so that the original contact area is completely exposed, avoiding the complex operations of removing the sling or manual supplementary painting in the traditional method, significantly reducing the difficulty of process implementation. The sling body is made of nylon material, which can improve the wear resistance of the sling, and at the same time can ensure that the sling on the cable tray can move towards both sides after swinging, so as to ensure the perfect progress of subsequent painting; (2) Under the action of the self-weight of the plugging cylinder, the plugging cylinder is engaged with the plugging seat, and the plugging seat and the hoisting conveyor are in a relatively static state. At the same time, with the cooperation of the anti-swing and stabilizing assembly, the two sling bodies can buffer the swaying force generated by the self-weight of the cable tray body under the combined action of the elastic force of the buffer spring and the oil pressure generated by the plugging cylinder, so as to prevent the cable tray body from shaking. Shaking will affect the adhesion between the paint film and the tray base material and reduce the anti-corrosion effect. Improving the stability of the tray during painting can ensure that the paint film fits tightly on the tray, and the corrosion resistance time of the salt spray test is significantly extended, improving the service life of the tray in harsh environments.

[0018] As Figures 1 to 10 shown, a conveying device for cable tray production provided by the present invention includes a hoisting conveyor frame 1 and a cable tray body 15. A hoisting conveyor 11 is installed on the hoisting conveyor frame 1. A hoisting seat 13 is fixedly arranged at an output end on one side of the hoisting conveyor 11 through a fixing strip 12. An anti-sway stabilizing assembly 2 is arranged on the hoisting seat 13. Two suspension rope bodies 14 are arranged at an output end on the other side of the hoisting conveyor 11. The cable tray body 15 is arranged between the two suspension rope bodies 14; The anti-sway stabilizing assembly 2 includes a socket cylinder 21 slidably connected to the hoisting seat 13. A connecting rope 131 is fixedly arranged at the bottom end of the hoisting seat 13. A socket base 22 is fixedly arranged at the bottom end of the connecting rope 131. A buffer plate 23 is fixedly arranged at the bottom end of the socket base 22. Two first buffer plates 24 are slidably arranged inside the buffer plate 23. Two second buffer plates 241 are slidably arranged inside the buffer plate 23. And the two suspension rope bodies 14 are respectively inserted between the two pairs of first buffer plates 24 and second buffer plates 241. An adjusting assembly 3 is arranged at the bottom of the buffer plate 23; The adjusting assembly 3 includes two lower extension plates 31 respectively fixed to the bottom ends of the two first buffer plates 24. An arc-shaped push rod 32 is fixedly arranged on each lower extension plate 31. An adjusting rotating rod 33 is rotatably arranged on the arc-shaped push rod 32. One end of the adjusting rotating rod 33 is rotatably connected to an adjusting main rod 34. And the adjusting main rod 34 is slidably connected to the buffer plate 23. An adjusting sleeve 35 is fixedly arranged on the adjusting main rod 34. And the adjusting sleeve 35 is sleeved on the outer wall of the suspension rope body 14; Two guide rods 211 are fixedly arranged at the top end of the socket cylinder 21. And the two guide rods 211 are both slidably connected to the hoisting seat 13. Electric push rod bodies 212 fixedly connected to the hoisting seat 13 are arranged on the two guide rods 211. Guide grooves matching the two guide rods 211 are formed in the hoisting seat 13. The two guide rods 211 are symmetrically arranged with respect to the connecting rope 131; Two insertion blocks 213 are fixedly arranged on the inner wall of the insertion cylinder 21, and the two insertion blocks 213 are symmetrically arranged with respect to the insertion cylinder 21. The insertion cylinder 21 is located above the insertion seat 22. An opening guiding groove matching the two insertion blocks 213 is formed on the insertion seat 22. Two hydraulic propulsion grooves 221 are formed on the insertion seat 22 below the opening guiding groove. A pair of first buffer plates 24 and a pair of second buffer plates 241 are symmetrically arranged with respect to the buffer disc 23. Two movable grooves matching the pair of first buffer plates 24 and the pair of second buffer plates 241 are formed on the buffer disc 23, and the two movable grooves are symmetrically arranged with respect to the buffer disc 23. The two adjusting rotating rods 33 are cross - arranged. Two limiting sleeves are fixedly arranged at the bottom of the buffer disc 23, and the two limiting sleeves are respectively slidably connected to the two adjusting main rods 34. Each suspension rope body 14 is made of nylon material. Two fixed pulleys are rotatably arranged on the top of the hoisting seat 13, and the outer arc walls of each fixed pulley are in contact with the outer wall of the suspension rope body 14. There is a certain gap between the two suspension rope bodies 14 and the top end of the cable tray body 15. When the cable tray body 15 is lifted and its surface needs to be spray - painted for the second time, the hoisting conveyor 11 can be started to make the cable tray body 15 below the fixed strip 12 move towards another paint baking room. At the same time, the cable tray body 15 can swing towards the direction of the first buffer plate 24. At this time, by power - off of the electric push rod body 212, the insertion cylinder 21 can freely fall under its own gravity. Then, the insertion blocks 213 on the insertion cylinder 21 can contact the opening guiding groove formed on the insertion seat 22 and slide along the opening guiding groove. Finally, the insertion blocks 213 on the insertion cylinder 21 can be engaged with the hydraulic propulsion grooves 221 formed on the insertion seat 22. At this time, the insertion seat 22 can be in a relatively static state with the hoisting conveyor 11 under the connection of the insertion cylinder 21. At this time, the two suspension rope bodies 14 can, under their own inertia, respectively contact the two first buffer plates 24 and push the two first buffer plates 24 to slide inside the buffer disc 23 simultaneously, and drive the lower extension plate 31 fixedly connected to the first buffer plate 24 to move, then drive the arc - shaped push rod 32 to move, and make the adjusting rotating rod 33 rotatably connected to the arc - shaped push rod 32 rotate around the connection position with the adjusting main rod 34, and at the same time push the adjusting main rod 34 to slide inside the limiting sleeve and push the adjusting sleeve 35 fixedly connected to the adjusting main rod 34 to slide. Since the two suspension rope bodies 14 are made of nylon material at this time, and the cable tray body 15 after the first spray - painting is relatively smooth, the cable tray body 15 sleeved inside the adjusting sleeve 35 can move. At this time, the two suspension rope bodies 14 both move towards both sides on the cable tray body 15, so that the parts covered by the pressure of the suspension rope bodies 14 on the cable tray body 15 are exposed outside again, which is convenient for the later second spray - painting.

[0019] Two first buffer plates 24 and two second buffer plates 241 are fixedly provided with arc-shaped piston rods 25. Each arc-shaped piston rod 25 is slidably connected to the buffer plate 23, and each arc-shaped piston rod 25 is inserted into the buffer plate 23. Each first buffer plate 24 and each second buffer plate 241 are fixedly provided with buffer springs 251 fixedly connected to the inner wall of the buffer plate 23. Each buffer spring 251 is sleeved on the arc-shaped outer wall of the arc-shaped piston rod 25. Propulsion seats 26 are slidably arranged inside two hydraulic propulsion grooves 221 respectively located on the plugging seat 22. Two hydraulic grooves matching with a plurality of arc-shaped piston rods 25 are formed inside the buffer plate 23, and the two hydraulic grooves are respectively communicated with the hydraulic propulsion grooves 221; Two communication grooves are formed inside the buffer plate 23, and two ends of each communication groove are respectively communicated with the communication groove and the hydraulic propulsion groove 221; When the cable tray body 15 is lifted and needs to be moved, first start the hoisting conveyor 11 to make the cable tray body 15 below the fixing strip 12 move to one side. During this process, the cable tray body 15 can swing to both sides and drive the buffer plate 23 fixedly connected to the lower part of the hoisting seat 13 through the connecting rope 131 to swing to both sides. At this time, by powering off the electric push rod body 212, the plugging cylinder 21 can freely fall under its own gravity, and then the plugging cylinder 21 is engaged with the plugging seat 22. At this time, the plugging seat 22 can be in a static state relative to the hoisting conveyor 11 under the connection of the plugging cylinder 21 and the guide rod 211. And at this time, the plugging block 213 on the plugging cylinder 21 can, under the gravity of the plugging cylinder 21, push the propulsion seat 26 on the plugging seat 22 to slide inside the hydraulic propulsion groove 221 and push the hydraulic oil inside the hydraulic propulsion groove 221 to enter the hydraulic groove through the communication groove. At the same time, the swinging of both sides of the cable tray body 15 can push the two first buffer plates 24 and the two second buffer plates 241 to slide on the buffer plate 23 and drive a plurality of arc-shaped piston rods 25 to slide inside the buffer plate 23, and simultaneously compress the buffer springs 251 sleeved on the arc-shaped outer walls of the arc-shaped piston rods 25. Then, under the cooperation of the elastic force of the buffer springs 251 and the oil pressure generated by the plugging cylinder 21, the swinging force generated by the self-weight of the cable tray body 15 can be buffered, thus playing a role in preventing the cable tray body 15 from shaking.

[0020] Working principle and usage process of the present invention: First, the cable tray body 15 is lifted by the lifting rope body 14. First, the cable tray body 15 is spray-painted for the first time. During the second spray-painting process, at this time, by starting the hoisting conveyor 11, the cable tray body 15 below the fixing strip 12 moves to one side. During this process, the cable tray body 15 can swing to both sides, and drives the buffer plate 23 fixedly connected to the lower part of the hoisting seat 13 through the connecting rope 131 to swing to both sides. At this time, by cutting off the power supply of the electric push rod body 212, the insertion cylinder 21 can freely fall under its own gravity, and then the insertion cylinder 21 is engaged with the insertion seat 22. At this time, the insertion seat 22 can be in a static state relative to the hoisting conveyor 11 under the connection of the insertion cylinder 21 and the guide rod 211. And at this time, the insertion block 213 on the insertion cylinder 21 can, under the gravity of the insertion cylinder 21, push the propulsion seat 26 on the insertion seat 22 to slide inside the hydraulic propulsion groove 221, and push the hydraulic oil inside the hydraulic propulsion groove 221 to enter the hydraulic groove through the communication groove. At the same time, the swinging of both sides of the cable tray body 15 can push the two first buffer plates 24 and the two second buffer plates 241 to slide on the buffer plate 23, and drive a plurality of arc-shaped piston rods 25 to slide inside the buffer plate 23, and at the same time compress the buffer springs 251 sleeved on the arc-shaped outer walls of the arc-shaped piston rods 25. Then, under the cooperation of the elastic force of the buffer spring 251 and the oil pressure generated by the insertion cylinder 21, the swinging force generated by the self-weight of the cable tray body 15 can be buffered. During this process, the two lifting rope bodies 14 can, under their own inertia, respectively contact the two first buffer plates 24, and push the two first buffer plates 24 to slide inside the buffer plate 23 at the same time, and drive the lower extension plate 31 fixedly connected to the first buffer plate 24 to move, and then drive the arc-shaped push rod 32 to move, and make the adjusting rotating rod 33 rotatably connected to the arc-shaped push rod 32 rotate around the connection position with the adjusting main rod 34, and at the same time push the adjusting main rod 34 to slide inside the limit sleeve, and push the adjusting sleeve 35 fixedly connected to the adjusting main rod 34 to slide, and finally make the cable tray body 15 sleeved inside the adjusting sleeve 35 move. At this time, both lifting rope bodies 14 move to both sides on the cable tray body 15, so that the parts covered by the oppression of the lifting rope bodies 14 on the cable tray body 15 are exposed outside again, which is convenient for the subsequent second spray-painting.
