Description

Technical Field

[0001] The invention relates to an anode carbon block assembly and unloading station and a traveling trolley thereof. Background Art

[0002] There are two types of loading and unloading trolleys for anode carbon block assembly and unloading stations in traditional processes: one is that the loading and unloading trolley is located inside the pit, and the loading and unloading trolley only has lifting and moving functions. The lifting action is driven by a hydraulic cylinder, but the cylinder is located inside the equipment and is difficult to maintain. The lifting mechanism uses a fork-shaped mechanism, which has a complex structure and a high failure rate. The anode tray needs to be transferred to other equipment for flipping, so that the anode trailer with residual anodes or new anodes cannot directly enter and exit the loading and unloading station, and can only rely on forklifts for secondary transfer, which has low work efficiency and cumbersome processes. The other type of loading and unloading trolley is located above the ground for operation. The operation of each mechanism on the loading and unloading trolley is driven by a motor reducer. The loading and unloading trolley does not have the function of guiding rods. The flipping mechanism on this type of loading and unloading trolley is driven by a motor reducer and gears. The structure is complex and the failure rate is high, and the flipping process is dusty. The loading and unloading trolley tray lifting device relies on the motor reducer to drive the wire rope to achieve the lifting action. Due to the complex intermediate transmission, the lifting process is prone to asynchronism and wire rope breakage, and the failure rate is high. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to make the technical purpose, technical solution and beneficial effects of the present invention more clear, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] Embodiment 1:

[0036] A walking trolley, such as Figure 1-12As shown, the walking trolley includes a walking base 1 which is symmetrically arranged on the left and right and moves synchronously. The two walking bases are connected by a horizontal square tube 2. A driven wheel 4 is installed at the front end of the walking base 1, and a driving wheel 3 is installed at the rear end of the walking base. The driving wheel is connected to a driving motor 5 installed on the walking base. The driving motor drives the driving wheel to drive the entire walking base 1 forward. The driving motor adopts variable frequency speed regulation to make the equipment run more smoothly.

[0037] A fixed seat 601 and a movable seat 602 are provided on each walking base 1. The fixed seat 601 is vertically welded or bolted to the walking base 1. The movable seat 602 is placed on the walking base. A pallet lifting cylinder 605 is also hinged on the walking base. The push rod of the pallet lifting cylinder is hinged to the movable seat 602. The push rods of the two pallet lifting cylinders 605 are synchronously extended and retracted to drive the two movable seats 602 to rise and fall synchronously. In order to ensure that the movable seat can be vertically lifted along the specified trajectory without deflection, two upper and lower parallel swing arms 603 are rotatably connected between the fixed seat 601 and the movable seat 602. The fixed seat, the movable seat and the two swing arms together constitute a parallelogram linkage mechanism located on the same vertical plane. That is, since the fixed seat 601 is vertically arranged, the lifting trajectory of the movable seat 602 must be lifted along the vertical plane. In addition, in order to ensure the synchronization of the lifting process of the movable seats on the two walking bases, the two swing arms 603 on the two walking bases are fixedly connected through the connecting pipe 604, so as to realize the rigid connection of the two swing arms 603, which further ensures the synchronization of the lifting of the left and right movable seats 602. Its main function is to drive the pallet to move up and down according to the predetermined trajectory. When working, the pallet lifting cylinder drives the lifting mechanism to move along the track trajectory, so that the pallet can be lifted and lowered according to the predetermined trajectory.

[0038] A pallet tilting shaft seat 701 is installed on the inner side of the movable seat 602, and a double rack swing hydraulic cylinder 703 is installed on the pallet tilting shaft seat. The two sides of the pallet tilting frame 702 are installed on the pallet tilting shaft seat 701 through the rotation of the rotating shaft, and the pallet tilting frame 702 can be synchronously lifted and lowered with the movable seat 602. In addition, the end of the rotating shaft is connected to the double rack swing hydraulic cylinder 703. Under the drive of the double rack swing hydraulic cylinder, the pallet tilting frame 702 can be independently flipped together with the rotating shaft. The inner side wall of the pallet tilting frame is installed with a pallet slot 704 formed by two layers of angle steel for loading the pallet, and the pallet slot can be installed into the pallet slot from the front side of the pallet tilting frame. A guard plate 705 is also vertically installed on the rear side of the pallet tilting frame 702. The function of the pallet tilting mechanism is to tilt the pallet so that the electrolyte in the pallet falls through the unloading chute onto the lower belt conveyor for transportation.

[0039] A guide rod positioning frame 802 capable of independent lifting along the inner wall of the movable seat is also installed on the inner side of the movable seat 602, wherein the independent lifting is realized by a straightening lifting cylinder 801 installed on the walking base 1, the push rod of the straightening lifting cylinder 801 is hinged with the guide rod positioning frame 802, and the push rod of the straightening lifting cylinder 801 is extended and retracted to drive the guide rod positioning frame to lift up and down. In order to ensure that the guide rod positioning frame 802 is lifted and lowered along a predetermined trajectory (i.e., lifted and lowered along the inner wall of the movable seat), a vertical guide rail 816 is vertically arranged on the inner side of the movable seat 602, and pairs of guide rollers 815 are respectively installed on the roller seat plates on both sides of the guide rod positioning frame 802, the guide rollers 815 are located on both sides of the vertical guide rail 816, and the wheel surface of the guide roller 815 can just roll along the side wall of the vertical guide rail. At the same time, in order to ensure the stability and synchronization of the lifting and lowering of the guide rod positioning frame 802, synchronous gears 818 are installed on both sides of the guide rod positioning frame. The synchronous gears on both sides are connected by a synchronous shaft 817, and a synchronous rack 819 meshing with the synchronous gear is vertically arranged on the inner side of the movable seat 602.

[0040] A pair of guide rod clamping is installed on the guide rod positioning frame 802. Each pair of guide rod clamping pairs includes an inclined roller frame 806 and a straight roller frame 807 located on both sides of the guide rod. The inclined roller frame 806 and the straight roller frame 807 can swing around their respective swing axes to move closer to or away from the guide rod, and the guide rod is vertically clamped between the inclined roller frame and the straight roller frame so that the guide rod and the carbon block are kept perpendicular. Specifically, as shown in the figure, four roller frame supports 803 are welded evenly at intervals on the front side of the guide rod positioning frame. The upper ends of the inclined roller frame 806 and the straight roller frame 807 are respectively rotated and installed in the steel grooves on both sides of the roller frame supports through their respective swing axes, so that the inclined roller frame and the straight roller frame between the two adjacent roller frame supports 803 cooperate to swing to form a pair of guide rod clamping pairs, and the guide rod extending from the middle of the guide rod clamping pair is straightened. The specific straightening structure is as follows: a rotating arm 811 is respectively sleeved on the end of each swing shaft, and each rotating arm 811 is hinged to a horizontal connecting rod 812, wherein the rotating arms of each inclined roller frame swing shaft 804 are hinged to the same horizontal connecting rod, and one of the rotating arms is hinged to the right-pushing straightening oil cylinder 813; the rotating arms of each straight roller frame swing shaft 805 are hinged to the same horizontal connecting rod, and one of the rotating arms is hinged to the left-pushing straightening oil cylinder 814, and the left-pushing straightening oil cylinder 814 is hinged to the left-pushing straightening oil cylinder 813. The push rods of the straightening cylinder 814 and the right straightening cylinder 813 move in opposite directions. When the push rods of the left straightening cylinder and the right straightening cylinder are extended at the same time, the inclined roller frame 806 and the straight roller frame 807 swing towards the direction close to the guide rod to straighten the guide rod. When the push rods of the left straightening cylinder 814 and the right straightening cylinder 813 are retracted at the same time, the inclined roller frame 806 and the straight roller frame 807 swing away from the guide rod to loosen the guide rod.

[0041] The inclined roller frame 806 is provided with an inclined roller 808 that diverges toward the outer end, and an auxiliary roller 809 is horizontally installed behind each pair of inclined rollers. A corresponding straight roller 810 is horizontally installed on the straight roller frame 807. When the inclined roller frame and the straight roller frame swing toward the direction close to the guide rod, the inclined roller 808, the auxiliary roller 809 and the straight roller 810 can roll along the surface of the guide rod respectively, so as to roll to the correct position, so that the two inclined rollers, the auxiliary rollers and the straight rollers jointly surround and clamp the guide rod to achieve fork-shaped straightening. During operation, the straightening lifting cylinder pushes the straightening mechanism to straighten the guide rod, and then the lifting mechanism pushes the straightening mechanism upward to straighten the top of the guide rod to the standard position. The mechanism adopts fork-shaped straightening, the straightening point starts from the lower part of the guide rod, and the straightening mechanism can move up and down, the range of the guide rod straightening is wider, and the straightening position is more standard, so that the guide rod assembly station process is smoother, and the assembly efficiency of the anode assembly station is greatly improved.

[0042] An anode carbon block assembly and unloading station comprises the walking trolley in Example 1.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto, and any equivalent substitutions of the present invention and modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
