Water treatment agents are an important category of fine chemicals and are highly specialized. Different uses and treatment targets require different water treatment methods. The production of water treatment agents requires the use of multiple raw materials and their mixing.

[0027] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0028] Example 1, see Figures 1 to 9 As shown, a raw material conveyor for preparing water treatment agents includes a vehicle body 1, the vehicle body 1 is connected to two sets of running mechanisms 2, the running mechanisms 2 are composed of a gearbox mounted on the vehicle body 1 and two sets of wheels coaxially connected to the gearbox, each set of running mechanisms 2 is mounted with a drive motor 3, the drive motor 3 is used to apply driving force to the running mechanisms 2, the vehicle body 1 is fixedly connected to a master control module 4, the vehicle body 1 is fixedly connected to a power storage module 5, the power storage module 5 is electrically connected to a charging shoe 6 mounted on the bottom of the vehicle body 1, and the power storage module 5 is charged by contacting and electrically connecting with a ground charging system mounted on the ground through the charging shoe 6, and further includes:

[0029] A column cargo structure 7 connected to the vehicle body 1 includes a vertical frame 8 connected to the vehicle body 1, and a cargo platform 9 is slidably connected to the vertical frame 8. A double telescopic transfer fork 10 is installed on the cargo platform 9. The double telescopic transfer fork 10 adjusts the position of the raw materials by actively extending and retracting in multiple stages;

[0030] Four groups of speed limiting winding mechanisms 11 connected to the vehicle body 1, the speed limiting winding mechanism 11 includes a fixed frame 12 fixedly connected to the vehicle body 1, the fixed frame 12 is connected to a first motor 13, the output shaft of the first motor 13 is fixedly connected to a rack 14, the rack 14 is movably connected to an overspeed separation part 15, the overspeed separation part 15 is connected to the fixed frame 12, the overspeed separation part 15 is connected to a hydraulic deceleration and braking part 16, the overspeed separation part 15 releases the limit of the hydraulic deceleration and braking part 16 and releases the power connection state between the overspeed separation part 15 and the rack 14 by centrifugal rotation, the hydraulic deceleration and braking part 16 is connected to a winding part 17, the hydraulic deceleration and braking part 16 is used to apply rotational torque and deceleration braking torque to the winding part 17, the winding part 17 is connected to the vehicle body 1, the winding part 17 is wound with a cable 18, and the cable 18 is fixedly connected to the cargo platform 9.

[0031] During normal use of the present invention, the walking mechanism 2 is placed on the ground or on a track on the ground, the charging shoe 6 is in contact with and electrically connected to the ground charging system on the ground, the driving motor 3 applies a driving force to the walking mechanism 2, so that the walking mechanism 2 moves and swings the vehicle body 1 to move, the moving vehicle body 1 drives the column loading structure 7 and the speed-limiting winding mechanism 11 to move, and after the double telescopic loading fork 10 moves the raw materials to the loading platform 9, the first motor 13 drives the rack 14 to rotate, the rack 14 drives the overspeed separation part 15, and the overspeed separation part 15 performs power transmission, so that the overspeed separation part 15 transmits the torque to the hydraulic deceleration brake part 16, and the hydraulic deceleration brake part 16 drives the winding part 17 to wind or release the cable 18, so that the cable 18 brings The dynamic loading platform 9 moves, and the loading platform 9 and the vertical frame 8 move relative to each other, so that the double telescopic loading fork 10 moves the raw materials to different positions, and then the double telescopic loading fork 10 transports the raw materials to the high-level shelves for stacking. If the first motor 13 is accidentally powered off or the output shaft of the first motor 13 rotates beyond the safe speed, the overspeed separation part 15 disengages from the insertion frame 14 by autonomous deformation to disconnect the power connection between the first motor 13 and the winding part 17, and the overspeed separation part 15 starts the hydraulic deceleration braking part 16, so that the hydraulic deceleration braking part 16 performs a deceleration braking operation to slow down and stop the winding part 17, limit the movement of the cable 18, and thereby avoid overspeed movement of the loading platform 9, thereby ensuring the safe operation of the present invention. The present invention moves the raw materials to be stacked through the mutual cooperation of the column loading structure 7 and the four sets of speed-limiting winding mechanisms 11, and controls the hydraulic deceleration braking part 16 through the overspeed separation part 15 to perform automatic braking operations when the present invention is overspeeding. The overspeed separation part 15 is separated from the insertion rack 14 to disconnect the power output of the first motor 13 to the winding part 17, further avoiding the risk of braking failure of the hydraulic deceleration braking part 16, thereby further improving the safety of the present invention.

[0032] In one case of this embodiment, the hydraulic deceleration braking part 16 includes a support frame 20 fixedly connected to the fixed frame 12, the support frame 20 is fixedly connected to the vehicle body 1, the support frame 20 is rotatably connected to a first rotating shaft 21, the first rotating shaft 21 is coaxially connected to the winding part 17, the first rotating shaft 21 is coaxially fixedly connected to a brake wheel 22, and double-grooved wheels 23 coaxially fixedly connected to the first rotating shaft 21 are provided on both sides of the brake wheel 22, the support frame 20 is fixedly connected to two groups of symmetrically arranged dovetail bars 24, the two groups of dovetail bars 24 are slidably connected to a group of counterweight blocks 25, the counterweight blocks 25 are fixedly connected to two groups of elastic plug-in accessories 26, the elastic plug-in accessories 26 limit the double-grooved wheels 23 by mutually engaging with the double-grooved wheels 23, and a plurality of groups of limiting slots 27 are provided on the counterweight blocks 25, and the limiting slots 27 are connected to the overspeed separation part 15 is movably connected, the overspeed separation part 15 is connected to two groups of dovetail bars 24, the overspeed separation part 15 is coaxially connected to the first rotating shaft 21, and two groups of piston rods 28 are fixedly installed under the counterweight block 25, the piston rod 28 is slidably connected to a cylindrical sleeve 29, the cylindrical sleeve 29 is fixedly connected to the support frame 20, the cylindrical sleeve 29 is fixedly connected to an arc sleeve 31 through a conduit 30, the arc sleeve 31 is fixedly connected to the support frame 20, the arc sleeve 31 is slidably connected to an arc pressure frame 32, and a brake pad 33 is fixedly installed on the side of the arc pressure frame 32 close to the brake wheel 22. The chamber enclosed by the cylindrical sleeve 29, the conduit 30, and the arc sleeve 31 is filled with a hydraulic oil layer 34 arranged between the piston rod 28 and the arc pressure frame 32, and the contact area between the piston rod 28 and the hydraulic oil layer 34 is smaller than the contact area between the arc pressure frame 32 and the hydraulic oil layer 34. The overspeed separation part 15 is separated from the limiting groove 27 to release the limiting of the counterweight 25 by the overspeed separation part 15. Under the action of gravity, the counterweight 25 slides downward along the dovetail bar 24, and the piston rod 28 under the counterweight 25 presses the hydraulic oil layer 34. The hydraulic oil layer 34 applies pressure to the arc-shaped pressing frame 32, and the arc-shaped pressing frame 32 drives the brake pad 33 to squeeze the brake wheel 22 to apply friction to the brake wheel 22, so that the brake wheel 22 drives the first rotating shaft 21 to decelerate. Since the contact area between the piston rod 28 and the hydraulic oil layer 34 is smaller than the contact area between the arc-shaped pressing frame 32 and the hydraulic oil layer 34, according to the hydraulic pressure, the first rotating shaft 21 is decelerated. The principle of the jack is to make the pressure applied by the hydraulic oil layer 34 to the arc-shaped pressure frame 32 greater than the pressure applied by the piston rod 28 to the hydraulic oil layer 34, thereby reducing the weight requirement of the counterweight block 25 and increasing the friction force applied to the brake wheel 22. As the brake wheel 22 drives the first rotating shaft 21 to decelerate, the rotation speed of the double-grooved wheel 23 decreases accordingly, so that the elastic plug-in accessories 26 for the falling counterweight block 25 have sufficient time to be connected to the double-grooved wheel 23, so that the stopped rotating double-grooved wheel 23 limits the rotation of the first rotating shaft 21. As the first rotating shaft 21 stops rotating, the winding part 17 stops moving at the same time to achieve braking operation.

[0033] In one aspect of this embodiment, the elastic plug-in fitting 26 includes a sleeve 35 fixedly connected to the counterweight 25. An electromagnet 36 is fixedly mounted within the sleeve 35. The electromagnet 36 is fixedly connected to a spring, which is fixedly connected to a latch bar 37 slidably connected to the sleeve 35. The latch bar 37 is ferromagnetic. If the latch bar 37 does not engage the double-grooved pulley 23 during the descent of the elastic plug-in fitting 26, the latch bar 37 abuts against the outer surface of the double-grooved pulley 23. At this time, due to the compressed spring, the latch bar 37 provides friction to the double-grooved pulley 23, thereby reducing the rotation speed of the double-grooved pulley 23. As the rotation speed of the double-grooved pulley 23 decreases and the notch of the double-grooved pulley 23 aligns with the latch bar 37, the latch bar 37 engages with the notch of the double-grooved pulley 23. The electromagnet 36 is used to magnetically attract the latch bar 37, thereby releasing the latch bar 37 from limiting the position of the double-grooved pulley 23.

[0034] In one case of this embodiment, the overspeed separation part 15 includes two groups of first elastic telescopic frames 38 fixedly connected to the fixed frame 12, and the movable ends of the two groups of first elastic telescopic frames 38 are fixedly connected to the rotation limit frames 39. The two groups of rotation limit frames 39 are jointly rotatably connected to the groove wheel 40 movably connected to the plug-in frame 14. The rotation limit frame 39 is used to provide rotation limit for the groove wheel 40. The groove wheel 40 is fixedly connected to the polygonal frame 41. The polygonal frame 41 is slidably connected to a sleeve shaft 42 coaxially fixedly connected to the first rotating shaft 21. The sleeve shaft 42 has a circumferential edge. Multiple groups of second elastic telescopic frames 43 are installed at equal angles, and the movable ends of the second elastic telescopic frames 43 are fixedly connected to a hinged platform 44, and two groups of symmetrically arranged hinged frames 45 are hinged on the hinged platform 44, one group of hinged frames 45 is hinged to the polygonal frame 41, and the other group of hinged frames 45 is hinged to a linkage disk 46 coaxially fixedly connected to the sleeve shaft 42, and the linkage disk 46 is rotatably connected to a slot frame 47, and the slot frame 47 is movably connected to the limiting through slot 27, and the slot frame 47 is slidably connected to two groups of guide frames 48, and the guide frames 48 are fixedly connected to the dovetail bar 24. The first motor 13 drives the plug-in frame 14 to rotate. When the plug-in frame 14 is engaged with the groove wheel 40, the rotating plug-in frame 14 drives the groove wheel 40 to rotate, and the groove wheel 40 drives the polygonal frame 41 to rotate, so that the polygonal frame 41 drives the sleeve shaft 42 to rotate, and the sleeve shaft 42 drives the first rotating shaft 21 and the linkage plate 46 to rotate, and the sleeve shaft 42 drives the second elastic telescopic frame 43 to rotate. As the speed of the sleeve shaft 42 exceeds the threshold, the centrifugal force of the articulated platform 44 overcomes the elastic force of the second elastic telescopic frame 43 and moves outward. At this time, the articulated platform 44 pulls the second elastic telescopic frame 43 to extend the second elastic telescopic frame 43. Length, the second elastic telescopic frame 43 pulls the articulated frame 45, and under the pulling of the articulated frame 45, the polygonal frame 41 drives the groove wheel 40 to separate from the insertion frame 14, and the linkage plate 46 is pulled by the articulated frame 45, and the linkage plate 46 drives the slot frame 47 to move during rotation, so that the slot frame 47 and the guide frame 48 move relative to each other, and the slot frame 47 and the limiting slot 27 are separated from each other to release the limit on the counterweight block 25, thereby realizing automatic braking of the overspeed separation part 15 in the absence of electricity, ensuring that the overspeed separation part 15 can operate normally even in the event of an unexpected power outage.

[0035] In one aspect of this embodiment, the winding portion 17 includes a first wheel frame 49 fixedly connected to the vehicle body 1. A winding wheel 50 is rotatably mounted on the first wheel frame 49 and coaxially fixedly connected to the first rotating shaft 21. The winding wheel 50 is wound around the cable 18. The first wheel frame 49 is fixedly connected to a second wheel frame 52. Four symmetrically arranged straightening wheels 53 are rotatably mounted on the second wheel frame 52. The straightening wheels 53 abut against the cable 18. The rotating first rotating shaft 21 drives the winding wheel 50 to rotate, and the winding wheel 50 winds the cable 18. The moving cable 18 drives the cargo platform 9 to move, and the four straightening wheels 53 provide movement guidance for the cable 18.

[0036] In one aspect of this embodiment, the stand 8 is fixedly connected to four sets of third wheel frames 51, and each set of third wheel frames 51 is rotatably mounted with two sets of driven wheels 54, which are in contact with the cables 18. The driven wheels 54 are used to provide reversing support for the cables 18.

[0037] Example 2, based on Example 1, refer to Figure 1 The vehicle body 1 is fixedly connected to a hydraulic buffer 55, which is arranged below the cargo platform 9. By arranging the hydraulic buffer 55 below the cargo platform 9, the hydraulic buffer 55 can provide a buffer for the falling cargo platform 9. When the deceleration effect of the hydraulic deceleration brake unit 16 is insufficient, the hydraulic buffer 55 can prevent the cargo platform 9 from directly impacting the vehicle body 1, thereby protecting the cargo platform 9 and the vehicle body 1.

[0038] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions, and alterations may be made to the embodiments without departing from the principles and spirit of the invention.
