Stacker electric control system fault-tolerant control device

Abstract

This utility model discloses a fault-tolerant control device for a stacker crane's electrical control system, including a fault-tolerant mechanism and a cover-opening mechanism. The fault-tolerant mechanism includes a mounting frame, a gear shaft rotatably passing through the top of the mounting frame, a base plate sleeved on the outside of the gear shaft, a main control module and a backup control module respectively mounted on both sides of the base plate, and a high-speed synchronous bus connecting the main control module and the backup control module. The high-speed synchronous bus line extends laterally through the base plate, and the base plate is movably disposed inside the mounting frame. In this utility model, when the main control module fails, the movable end of the electric push rod drives the gear shaft and the base plate to rotate through the gear plate. Then, the main control module and the backup control module exchange positions, allowing the main control module to move to the back of the mounting frame, providing sufficient maintenance space for technicians. Here, the rotation of the gear shaft will rewind the pull rope, and then the buckle plate will be lifted, facilitating quick maintenance by technicians.

Description

Technical Field

[0001] This utility model relates to the field of fault-tolerant technology of electronic control systems, specifically a fault-tolerant control device for a stacker crane electronic control system. Background Technology

[0002] During the use of a stacker crane, in order to prevent the stacker crane from stopping due to system failure, a dual-system mode is set up. The backup control system can be used to enable the stacker crane to continue to work.

[0003] However, this also easily leads to a problem: in the dual-system coexistence mode, the already small installation space becomes even narrower, making it difficult for technicians to operate and causing inconvenience to maintenance work. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A fault-tolerant control device for a stacker crane's electrical control system includes a fault-tolerant mechanism and a cover-opening mechanism. The fault-tolerant mechanism includes a mounting frame, a gear shaft rotatably passing through the top of the mounting frame, a base plate sleeved on the outside of the gear shaft, a main control module and a backup control module respectively mounted on both sides of the base plate, and a high-speed synchronous bus connecting the main control module and the backup control module. The high-speed synchronous bus line extends laterally through the base plate. The base plate is movably disposed inside the mounting frame. The cover-opening mechanism includes a toothed plate meshing with one side of the gear shaft, an electric push rod connected between the mounting frame and the toothed plate, a buckle plate rotatably mounted on one side of the mounting frame, and a pull rope connected between the gear shaft and the buckle plate.

[0007] By adopting the above technical solution, when the main control module fails, the movable end of the electric push rod drives the gear shaft and base plate to rotate through the toothed plate. Then, the main control module and the backup control module exchange positions, so that the main control module comes to the back of the mounting frame, giving technicians enough space for maintenance. Here, the rotation of the gear shaft will rewind the pull rope, and then the buckle plate will be lifted, which will facilitate technicians to quickly repair.

[0008] In a preferred embodiment, the present invention can be further configured such that the fault-tolerant mechanism further includes a multiplexer, which is located on one side of the main control module and is fixedly connected to the substrate.

[0009] In a preferred embodiment, the present invention can be further configured such that: a shallow groove is provided on the top of the mounting frame, the depth of which is equal to the diameter of the pull rope.

[0010] In a preferred embodiment, the present invention can be further configured such that: the outer end of the shallow groove is provided with an arc surface, and the rope body is in contact with the arc surface.

[0011] In a preferred embodiment, the present invention can be further configured such that: a support component is provided at the bottom of the mounting frame, the support component includes two legs fixedly connected to the bottom of the mounting frame, and a plurality of bolts screwed to the legs, the plurality of bolts being equally spaced and arranged in a row.

[0012] In a preferred embodiment, the present invention can be further configured such that: two support rods are rotatably embedded on the inner side of the buckle plate, and two sockets suitable for inserting the support rods are opened on one side of the mounting frame.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, when the main control module fails, the movable end of the electric push rod drives the gear shaft and base plate to rotate through the toothed plate. Then, the main control module and the backup control module exchange positions, so that the main control module comes to the back of the mounting frame, giving technicians enough space for maintenance. Here, the rotation of the gear shaft will rewind the pull rope, and then the buckle plate will be lifted, which facilitates quick maintenance by technicians.

[0015] 2. In this utility model, the main control module is responsible for the operation of the stacker crane, and then the high-speed synchronous bus transmits the execution commands in the main control module to the backup control module in real time, so as to ensure that the backup control module can seamlessly take over the control of the stacker crane when the main control module fails.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of a stacker crane electrical control system fault-tolerant control device provided by this utility model.

[0027] Example 1:

[0028] Combination Figure 1-3 As shown, the present invention provides a fault-tolerant control device for a stacker crane electrical control system, including a fault-tolerant mechanism 100 and a cover opening mechanism 200. The fault-tolerant mechanism 100 includes a mounting frame 110, a gear shaft 120 rotatably passing through the top of the mounting frame 110, a base plate 130 sleeved on the outside of the gear shaft 120, a main control module 140 and a backup control module 150 respectively mounted on both sides of the base plate 130, and a high-speed synchronous bus 160 connecting the main control module 140 and the backup control module 150. The high-speed synchronous bus 160 line extends laterally through the base plate 130, and the base plate 130 is movably disposed inside the mounting frame 110.

[0029] The cover opening mechanism 200 includes a toothed plate 210 meshing with one side of the gear shaft 120, an electric push rod 220 connected between the mounting frame 110 and the toothed plate 210, a buckle plate 230 rotatably mounted on one side of the mounting frame 110, and a pull rope 240 connected between the gear shaft 120 and the buckle plate 230.

[0030] Furthermore, the fault-tolerant mechanism 100 also includes a multiplexer 170, which is located on one side of the main control module 140 and fixed to the substrate 130. The multiplexer 170 can ensure that no signal glitches or interruptions occur during the switching process between the main control module 140 and the backup control module 150.

[0031] Furthermore, two support rods 400 are rotatably embedded inside the buckle plate 230, and two sockets suitable for inserting the support rods 400 are opened on one side of the mounting frame 110. The support rods 400 can make the buckle plate 230 open stably, allowing technicians to work safely under the buckle plate 230.

[0032] Example 2:

[0033] Combination Figure 1-3 As shown, based on Embodiment 1, a shallow groove is provided on the top of the mounting frame 110. The depth of the shallow groove is equal to the diameter of the pull rope 240. The shallow groove provides conditions for winding up the pull rope 240.

[0034] Furthermore, the shallow groove has an arc-shaped outer end, and the pull rope 240 body fits into the arc-shaped surface. This arc-shaped design can reduce wear and tear on the pull rope 240 during movement and ensure the service life of the pull rope 240.

[0035] Example 3:

[0036] Combination Figure 1 and Figure 3 As shown, in the above embodiment, the bottom of the mounting frame 110 is provided with a support component 300. The support component 300 includes two legs 310 fixedly connected to the bottom of the mounting frame 110 and a plurality of bolts 320 screwed to the legs 310. The plurality of bolts 320 are evenly spaced and arranged in a row. The legs 310 and the bolts 320 cooperate to securely connect the mounting frame 110 to external instruments.

[0037] The working principle and usage process of this utility model are as follows: In the initial state, the main control module 140 is responsible for the operation of the stacker crane. Then, the high-speed synchronous bus 160 transmits the execution commands in the main control module 140 to the backup control module 150 in real time, ensuring that the backup control module 150 can seamlessly take over the control of the stacker crane when the main control module 140 fails. At the same time, the movable end of the electric push rod 220 drives the gear shaft 120 and the base plate 130 to rotate through the toothed plate 210. Then, the main control module 140 and the backup control module 150 exchange positions, so that the main control module 140 comes to the back of the mounting frame 110, giving technicians enough maintenance space. Here, the rotation of the gear shaft 120 will retract the pull rope 240, and then the buckle plate 230 will be lifted, which will facilitate technicians to quickly carry out maintenance.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
