Description

Technical Field

[0001] The present invention relates to the technical field of monorail transportation track production, and specifically to a production line for monorail transporter tracks. Background Art

[0002] Monorail transporters are widely used in the mechanical transportation of orchards in mountainous areas of Southwest China due to their simple structure, good economy, flexible track laying, and less damage to the orchard terrain. They have good ductility and terrain adaptability. Among them, existing monorail transporters are mostly equipped with rack-shaped monorail transporters. The driving wheel with rollers distributed in a circle rotates and cooperates with a straight-profile rack to drive the overall transporter to run upward. The track body is formed by docking a track square tube and a track rack. With the gradual rise of monorail transporters, the demand for building and installing monorail transporter tracks has increased significantly, and the demand for track production has also increased substantially.

[0003] In the prior art, in order to produce and prepare a track body formed by docking a track square tube and a track rack, for the production and preparation of the track rack, the applicant submitted a Chinese utility model patent application "A Monorail Rack Pressing Machine" with the patent application number 202021411697.9, which is used to press a rack steel strip into a track rack; while the track square tube can be directly wound and formed by a square tube forming machine in the prior art. However, the formed track square tube and track rack are separate components, and welding operations are still required to connect and fix them into a track body. The track body also needs to be evenly cut into segments to facilitate splicing and installation adapted to the terrain in the mountains. However, due to the forming actions of the square tube forming machine and the rack pressing machine in the prior art being continuous and set-rate forming actions, ordinary automatic welding torches and cutting machines cannot complete the corresponding welding and sawing actions at corresponding positions during continuous operations. Therefore, in the prior art, both welding operations and sawing operations are manual operations, which have many defects and deficiencies: First, the stability of manual operations is poor, and the actions of operators will affect the positions of the track rack and the track square tube, resulting in skewness and difficulty in accurately centering; Second, the efficiency of manual welding is low, and the labor cost is high, which further affects the production cost; Third, it is difficult to ensure that there are no gaps between the rack and the track square tube during manual welding, and thus it is easy to have void welding; Fourth, after manual welding is completed, the track needs to be manually sawed, which is likely to cause the half teeth of the two tracks to be difficult to perfectly fit, resulting in offset teeth during the building and installation, which is not conducive to the stable operation of the track transporter. Therefore, there is an urgent need for a production line that replaces manual labor with automation and can achieve synchronous action production to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a production line for monorail transporter tracks with high automation that can perform synchronous action forming, welding, and sawing in view of the above-mentioned prior art deficiencies.

[0005] To achieve the above object, the technical solution of the production line for the monorail transporter track provided by the present invention is as follows: A production line for the monorail transporter track includes: a rack steel strip loader, on which a wound rack steel strip material is provided for supplying the formation of the track rack; a square tube steel strip loader, on which a wide-strip wound square tube steel strip material is provided for supplying the formation of the track square tube; a rack press, which is connected to the rack steel strip material loaded by the rack steel strip loader and is used for pressing the rack steel strip material into the track rack; a square tube forming machine, which is set as a multi-station progressive bending square tube forming machine, and the feeding end is connected to the square tube steel strip material fed by the square tube steel strip loader for forming the track square tube; an automatic synchronous welding machine, which is arranged at the rear ends of the square tube forming machine and the rack press. The track rack and the track square steel formed by the square tube forming machine and the rack press are butt-jointed and limitedly docked at the automatic synchronous welding machine. The automatic synchronous welding machine is provided with a welding channel, and a guiding and limiting device for limiting the material position and feeding path and a synchronous welding device for synchronously welding following the movement of the material are arranged corresponding to the welding channel, so that the track rack and the track square steel can be welded by the automatic synchronous welding machine to form a track profile; the synchronous cutting machine is butt-jointedly arranged at the rear end of the automatic synchronous welding machine and includes a synchronous slide table and a cutting unit. The cutting unit is arranged at the end of the synchronous slide table. The synchronous slide table makes a displacement action corresponding to the overall feeding rate, and the cutting unit performs segmented cutting on the track profile; an electric control box, in which a PLC controller is arranged. The PLC controller is respectively connected to the rack steel strip loader, the square tube steel strip loader, the rack press, the square tube forming machine, the automatic synchronous welding machine, the spray drying and cooling device and the synchronous cutting machine. Through the overall setting and control of the PLC controller, the synchronous operation of each component is realized. Through the PLC, the synchronous operation of each device on the production line is controlled. The main body corresponds to the synchronous actions of the rack press, the synchronous welding machine and the synchronous cutting machine by the forming and feeding speed of the square tube forming machine, so that the material can be directly automatically produced from the steel strip into segmented track sections.

[0006] As a further solution: The rack press is arranged at the upper middle part of the square tube forming machine. Its feeding end and discharging end are mutually matched with the forming channel arranged on the square tube forming machine. The track rack formed by the rack steel strip through the rack press can be vertically placed on the upper end surface of the track square tube formed by the square tube forming machine under its own gravity and can be jointly formed and butt-jointed at the front end of the automatic synchronous welding machine with the track square tube. The position setting of the rack press can make the formed track rack and the track square tube be in the same plane, which is convenient for the convergent butt-joint and subsequent welding station limit welding.

[0007] As a further solution: the discharge ends of the rack steel strip feeder and the square tube steel strip feeder are set to adapt to the heights of the feeding ends of the rack press and the square tube forming machine.

The slide table of the linear transmission mechanism can drive the welding mechanism and the vertically pressing mechanism to move synchronously with the material and reset after welding is completed. To achieve the synchronous welding effect of the automatic synchronous welding machine, the welding mechanism needs to feed synchronously with the corresponding welding end of the material, so the linear transmission mechanism is required to drive the displacement. In order to avoid false welding and missed welding, the vertically pressing mechanism needs to press the track rack and the end of the track square tube, and it is also convenient for the welding mechanism to position and weld in the pressed state.

[0009] As a further solution: the cutting unit of the synchronous cutting machine includes a cutting machine, a lifting cylinder that drives the cutting machine to operate, and a clamping mechanism that limits the track profile.

[0032] The control module is arranged in the electric control box 8, and the control module is set as a PLC controller. The PLC controller is respectively butt-jointed with the rack steel belt feeding machine 1, the square pipe steel belt feeding machine 2, the rack pressing machine 4, the square pipe forming machine 3, the automatic synchronous welding machine 5, the spray drying and cooling device 6 and the synchronous cutting machine 7. Through the overall setting and control of the PLC controller, the synchronous operation of each component is realized. The PLC controls the synchronous operation of each device on the production line. The main body corresponds to the synchronous actions of the rack pressing machine, the synchronous welding machine and the synchronous cutting machine according to the forming and feeding speed of the square pipe forming machine, so that the material can be directly automatically produced from the steel belt into segmented track sections.

[0033] The principle of the present invention is as follows: The production line of the present invention is based on the PLC controller set in the electric control box to control the synchronous speed of the rack steel belt loader 1, square tube steel belt loader 2, rack pressing machine 4, square tube forming machine 3, automatic synchronous welding machine 5, spray drying and cooling device 6 and synchronous cutting machine 7 on the production line. Since the whole square tube forming machine is large and its feeding speed is not easy to change, the feeding speed of the square tube forming machine 3 is mainly used as the overall feeding speed. The PLC controller adjusts the engine of the rack pressing machine 4 and the rotation speeds of the rack steel belt loader 1 and the square tube steel belt loader 2 to achieve synchronous forming and feeding as a whole. An automatic synchronous welding machine 5 is connected to the rear ends of the rack pressing machine 4 and the square tube forming machine 3 to converge and dock the formed track rack 12 and track square tube 13. The upper limit wheel 53 and the lower driving wheel 54 on the limit wheel group are used to limit the track rack 12 and the track square tube 13, and a plurality of guide wheel groups 55 are arranged on the feeding side for limiting. A synchronous welding device capable of performing welding operations synchronously is provided in the welding channel to weld the track rack and the track square tube. The welded track profile 14 then enters the spray drying and cooling device 6 for continuous spraying, drying and cooling operations, and finally is fed to the synchronous cutting machine 7 for synchronous cutting operations. At the same time, the PLC controller respectively synchronously sets the synchronous sliding table and the cutting unit on the synchronous cutting machine 7 and the synchronous welding device on the automatic synchronous welding machine 5, so that the overall welding and cutting operations can work synchronously according to the feeding speed of the square tube forming machine.During specific operations, the square tube forming machine 3, the rack pressing machine 4, and the corresponding rack steel strip feeder 1 and square tube steel strip feeder 2 are started and run, driving the synchronous forming of the materials. The track square tube formed by the square tube forming machine and the track rack pressed by the rack pressing machine are continuously conveyed to the front end of the automatic synchronous welding machine, guided and limited by the limit wheel set and the guide wheel set. The operation program set by the PLC controller controls the ejection of the double-axis cylinder 56, and the rack gripper 67 is lowered to clamp into the bottom end of the teeth of the track rack, pressing the contact end face between the track rack and the track square tube. Among them, the welding torch 69 is arranged in an upper butt joint at the welding point because the welding torch bracket 511 is connected to the gripper tooth connecting arm 58. The overall material continues to feed, and the linear transmission mechanism 512 drives the upper overall welding mechanism and the vertical pressing mechanism to make synchronous displacement with the track square tube and the track rack. During this period, the PLC control program controls the pneumatic operation of the welding machine switch to weld at the welding points of the track rack and the track square tube. After welding is completed, the double-axis cylinder releases and returns, and the linear transmission mechanism also returns to its original position for the next welding operation; after welding the track square tube and the track rack, a complete track profile is formed, and after passing through the spray cooling and drying device, it enters the synchronous cutting machine end. According to the preset track section length dimension, the control program set in the PLC controller controls the action of the clamping cylinder, and the synchronous motor drives the synchronous slide table to perform synchronous actions at the feeding speed of the square tube forming machine 3. During this period, the lifting 77 returns to drive the cutting machine 76 to perform sawing operations on the track profile. When the sawing operation is completed, the synchronous motor drives the synchronous slide table to return to its original position for the next sawing operation. The whole of the present invention is set on an orbital production line composed of multiple devices, and the PLC controller controls the synchronous operation and production of each device, enabling the materials to be directly automatically produced from the steel strip into segmented track sections, realizing the automated production line of the single-rail transporter track. The overall automation level is high, the dependence on manpower is low, the production cost is greatly reduced, and the production efficiency and the quality of the track sections are greatly improved, essentially solving the problems existing in the prior art.
