[0001] This invention relates to the field of emergency stop system design and modification for mechanical equipment, specifically an emergency stop device to prevent misoperation that can be installed on old mechanical mixing equipment. Background Technology

[0002] Mixing equipment is a key piece of equipment used to mix different materials and make them react fully. It is widely used in many fields such as chemical industry, new energy, bioengineering, environmental protection, food and beverage, metallurgy and mining. When using old mechanical mixing equipment, the motor may fail, causing the mixing rod to rotate out of control, which poses a safety hazard. Therefore, an emergency stop device is required.

[0003] Existing emergency stop devices generally rely on manually turning off the power or operating ordinary buttons on the control cabinet to stop the machine. However, the switch buttons are usually directly located on old mechanical mixing equipment, which poses a risk of switch failure and increases the probability of accidents. To address these issues, existing equipment needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide an emergency stop device for preventing misoperation that can be installed on old mechanical mixing equipment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an emergency stop device for preventing misoperation that can be installed on old mechanical mixing equipment, comprising an arc-shaped support plate and an arc-shaped rotating plate. Mounting blocks are fixed at equal intervals on the outer wall of the arc-shaped support plate. Two slide rails are fixed on the inner wall of the arc-shaped support plate. Two sliders are fixed on the outer wall of the arc-shaped rotating plate, and the sliders are slidably connected within the slide rails. An emergency stop mechanism is fixed on the inner wall of the arc-shaped rotating plate. The emergency stop mechanism includes a first spring, with movable blocks fixed to the inner ends of each first spring. A movable rod is fixed to the outer side of each movable block. The movable rod passes through the arc-shaped rotating plate and is rotatably connected to a roller. A rotating block is rotatably connected to the inner end face of the movable block. A movable plate is fixed to the inner end face of the rotating block. A rubber clamp is fixed to the inner end face of the movable plate by a second bolt.

[0006] Preferably, there are three first springs, and the three first springs are distributed at equal intervals on the arc-shaped rotating plate.

[0007] Preferably, a first bolt is threaded onto one side of the movable block, and an insertion hole is provided on the rotating block, into which the first bolt is inserted.

[0008] Preferably, the arc-shaped rotating plate has a groove, and a locking block is slidably connected in the groove. The locking block is connected to the top of the groove by a second spring.

[0009] Preferably, the top of the movable rod has a slot, and the locking block is engaged in the slot.

[0010] Preferably, a pull rod is fixed to the top of the card block, and the pull rod passes through the top of the arc-shaped rotating plate.

[0011] Preferably, the inner end face of the movable plate is fixed with a clamping plate at equal intervals, and the outer end face of the rubber clamping plate is provided with inclined grooves at equal intervals, and the clamping plate is engaged and connected in the inclined groove.

[0012] Preferably, an arrow mark is fixed to the top of the movable block.

[0013] Preferably, three extrusion blocks are fixed at equal intervals on the inner wall of the arc-shaped support plate, and the three rollers abut against the three extrusion blocks respectively.

[0014] Preferably, the top of the arc-shaped support plate is connected to the arc-shaped moving plate via an electric telescopic rod, and the arc-shaped moving plate abuts against the inner top of the three pull rods.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This anti-misoperation emergency stop device, which can be installed on old mechanical mixing equipment, achieves emergency stop in case of malfunction through the coordinated use of an arc-shaped rotating plate, a movable block, a movable rod, rollers, rubber clamps, a locking block, a pull rod, a squeezing block, and an arc-shaped moving plate. The device is installed on the top cover of the old mechanical mixing equipment, with the mixing rod positioned between three rubber clamps. When the mixing rod rotates out of control, the operator uses an external control to extend the electric telescopic rod. The arc-shaped moving plate moves upward, causing the three pull rods to move upward, the locking block moves upward to unlock the movable rod, the movable block automatically pops open, and the three rubber clamps clamp the mixing rod. Then, the three rubber clamps and the arc-shaped rotating plate rotate together with the mixing rod, the squeezing block squeezes the rollers, and the three rubber clamps clamp the mixing rod again, thus achieving an emergency stop. Furthermore, the electric telescopic rod is not directly connected to the clamping components, effectively protecting the electric telescopic rod.

[0016] 2. This anti-misoperation emergency stop device, which can be installed on old mechanical mixing equipment, achieves the purpose of preventing deformation and facilitating replacement through the coordinated use of a rotating block, a movable plate, a rubber clamp, and an inclined chute. The rotating block is rotatable, and the direction of the inclined chute can be adjusted by rotating the rotating block and the movable plate before using the device, so that the direction of the inclined chute is opposite to the rotation direction of the mixing rod, which can effectively prevent the deformation of the rubber clamp. The rubber clamp and the movable plate are detachable, and the rubber clamp is replaceable. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 6 This invention provides a technical solution: an emergency stop device for preventing misoperation that can be installed on old mechanical mixing equipment, comprising an arc-shaped support plate 1 and an arc-shaped rotating plate 5. Mounting blocks 2 are fixed at equal intervals on the outer wall of the arc-shaped support plate 1. Two slide rails 3 are fixed on the inner wall of the arc-shaped support plate 1. Two sliders 4 are fixed on the outer wall of the arc-shaped rotating plate 5, and the sliders 4 are slidably connected within the slide rails 3. An emergency stop mechanism 6 is fixed on the inner wall of the arc-shaped rotating plate 5. The emergency stop mechanism 6 includes a first spring 601, with movable blocks 602 fixed to the inner ends of the first spring 601. Movable rods 603 are fixed to the outer sides of the movable blocks 602. The movable rods 603 pass through the arc-shaped rotating plate 5 and are rotatably connected to rollers 604. A rotating block 605 is rotatably connected to the inner end face of the movable block 602. A movable plate 609 is fixed to the inner end face of the rotating block 605. A rubber clamp 610 is fixed to the inner end face of the movable plate 609 by a second bolt 611.

[0021] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, there are three first springs 601, and the three first springs 601 are evenly distributed on the arc-shaped rotating plate 5. Each first spring 601 has a movable block 602 fixed at its inner end. The first spring 601 is initially in a compressed state. After the movable rod 603 is unlocked, the movable block 602 will automatically spring open under the action of the first spring 601. The three movable blocks 602 will come together, the three movable plates 609 will come together, and the three rubber clamps 610 can automatically clamp the stirring rod on the stirring device.

[0022] In this embodiment, as Figure 3 , Figure 4 and Figure 6 As shown, a first bolt 606 is threadedly connected to one side of the movable block 602. A socket 607 is provided on the rotating block 605. The first bolt 606 is inserted into the socket 607. The rotating block 605 can rotate within the movable block 602. The movable plate 609 can rotate together with the rotating block 605 to facilitate adjustment of the direction of the movable plate 609. Before rotating the movable plate 609, the first bolt 606 needs to be loosened and removed from the socket 607 to facilitate unlocking the rotating block 605. After rotating the movable plate 609 180 degrees, the first bolt 606 is tightened and inserted into the socket 607 to facilitate locking the rotating block 605.

[0023] In this embodiment, as Figure 4 As shown, the arc-shaped rotating plate 5 has a groove 7, and a locking block 9 is slidably connected in the groove 7. The locking block 9 is connected to the top of the groove 7 through a second spring 8. The locking block 9 is initially locked on the movable rod 603, and the movable rod 603 is in a locked state. After the locking block 9 moves up and is completely retracted into the groove 7, the movable rod 603 can be unlocked. The second spring 8 can assist the locking block 9 to reset.

[0024] In this embodiment, as Figure 4 As shown, the top of the movable rod 603 has a slot 10, and the locking block 9 is engaged in the slot 10. When the locking block 9 is engaged in the slot 10, it can lock the movable rod 603. After the locking block 9 moves up and leaves the slot 10, the movable rod 603 can be unlocked.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a pull rod 11 is fixed to the top of the locking block 9, and the pull rod 11 passes through the top of the arc-shaped rotating plate 5. When the pull rod 11 moves upward, it can drive the locking block 9 to move upward, making it convenient to unlock the movable rod 603.

[0026] In this embodiment, as Figure 3 , Figure 4 and Figure 6As shown, the inner end face of the movable plate 609 is fixed with clamping plates 612 at equal intervals, and the outer end face of the rubber clamping plate 610 is provided with inclined grooves 613 at equal intervals. The clamping plates 612 are engaged and connected in the inclined grooves 613. The movable plate 609 can rotate, which makes it easy to adjust the direction of the inclined grooves 613. Before installing the device, the direction of the inclined grooves 613 can be adjusted according to the rotation direction of the stirring rod on the stirring equipment, so that the direction of the inclined grooves 613 is opposite to the rotation direction of the stirring rod. When the stirring rod rotates, the rubber clamping plate 610 and the stirring rod form a resistance, which can effectively prevent the rubber clamping plate 610 from deforming.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, an arrow mark 608 is fixed on the top of the movable block 602. The arrow mark 608 marks the direction of the inclined groove 613, so that the workers can more clearly understand the direction of the inclined groove 613.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, three extrusion blocks 12 are fixed at equal intervals on the inner wall of the arc-shaped support plate 1. Three rollers 604 abut against the three extrusion blocks 12 respectively. After the three rubber clamps 610 initially clamp the stirring rod on the stirring device, the arc-shaped rotating plate 5 will rotate together with the stirring rod. At this time, the rollers 604 roll on the extrusion blocks 12. The extrusion blocks 12 exert a squeezing effect on the rollers 604, the movable rod 603 and the movable block 602. The three rubber clamps 610 can clamp the stirring rod again to secure it, which facilitates the effect of emergency stop.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the top of the arc-shaped support plate 1 is connected to the arc-shaped moving plate 14 via an electric telescopic rod 13, and the arc-shaped moving plate 14 rests against the inner top of the three pull rods 11. The arc-shaped moving plate 14 can move upward under the extension of the electric telescopic rod 13, thereby supporting the three pull rods 11 to move upward, and the three locking blocks 9 move upward accordingly, making it convenient to unlock the three movable rods 603.

[0030] The method of use and advantages of this invention: This emergency stop device for preventing misoperation, which can be installed on old mechanical mixing equipment, works as follows: like Figures 1 to 6As shown: First, the arc-shaped support plate 1 is installed onto the top cover of the old mechanical mixing equipment using the mounting block 2 and external bolts. The mixing rod is located between the three rubber clamps 610. When the motor malfunctions and causes the mixing rod to rotate out of control, the operator controls the electric telescopic rod 13 to extend by operating the external control device. The arc-shaped moving plate 14 moves upward, supporting the three pull rods 11 to move upward. The upward movement of the pull rods 11 causes the locking block 9 to move upward, and the locking block 9 leaves the locking slot 10, thereby unlocking the movable rod 603. The movable block 602 automatically springs open under the action of the first spring 601. The three rubber clamps 610 clamp the mixing rod, and then the three rubber clamps 610 rotate together with the mixing rod. The arc-shaped rotating plate 5 rotates, the slider 4 slides in the slide rail 3, and the roller 604 rolls on the extrusion block 12, extruding... The pressure block 12 squeezes the roller 604, causing the movable rod 603 and movable block 602 to move. The three rubber clamps 610 clamp the stirring rod again, thus achieving an emergency stop. The direction indicated by the arrow 608 is the direction of the inclined groove 613. Before using the device, the direction of the inclined groove 613 can be adjusted by rotating the rotating block 605 and the movable plate 609 so that the direction of the inclined groove 613 is opposite to the rotation direction of the stirring rod. This can effectively prevent the rubber clamps 610 from deforming. Before rotating the rotating block 605 and the movable plate 609, the first bolt 606 needs to be loosened and moved away from the insertion hole 607 to unlock the rotating block 605. After rotating the rotating block 605 and the movable plate 609, the first bolt 606 is tightened and inserted into the insertion hole 607 to lock the rotating block 605.

[0031] In summary, this emergency stop device, which can be installed on old mechanical mixing equipment, achieves the goals of emergency stop in case of failure, prevention of deformation, and convenient replacement, thus meeting people's usage needs.
