Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen production equipment by water electrolysis, and particularly relates to an electrolytic cell plate flipping tooling and a working method thereof. Background Art

[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Currently, megawatt-level alkaline electrolytic cells usually consist of hundreds of electrolytic chambers, and each chamber is composed of two circular electrode plates. On the front and back sides of each plate, a number of hydrogen and oxygen channels are evenly distributed. During the production and manufacturing process of the plates, the hydrogen and oxygen channels need to be processed. After the front processing operation of the electrolytic cell plate is completed on the front side of the plate, it is necessary to manually flip the electrolytic cell plate by 180°, and then send it to the reverse processing operation for the reverse processing of the electrolytic cell plate. The diameter of a single plate is generally between 1500 mm and 2500 mm, and the weight is about 180 kg - 250 kg per plate. For traditional plate flipping, magnetic lifting equipment is usually used to lift it onto the flipping mechanism, and then a fixture is used to fix the plate for flipping. After flipping is completed, the fixture is removed and lifted to the next process. During this process, the amount of work for workers is large, the working steps are cumbersome, the process takes a long time, and an additional plate flipping device needs to be set up, increasing the equipment investment. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an electrolytic cell plate flipping tooling and a working method thereof, which reduce the amount of work of operators and shorten the time-consuming of the process.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0006] In a first aspect, an embodiment of the present invention provides an electrolytic cell plate flipping tooling, including two clamping rods. The two clamping rods are rotatably connected at a set position other than the end to form a clamping mechanism. Sling holes are provided at the top ends of the two clamping rods, and plate fixtures matching the plates are provided at the bottom ends. Plate fixing members are provided on the plate fixtures to fix the plate fixtures and the plates, and the plate fixtures are rotatably connected to the bottom ends of the clamping rods so that the plate fixtures can drive the plates to flip.

[0007] Optionally, the inner side of the plate fixture for cooperating with the plate is provided with a slot matching the plate. The plate fixing member is threadedly connected to the plate, and the plate fixing member extends into the slot so that the plate fixing member can press the edge of the plate against the inside of the slot along the axis direction of the plate.

[0008] Optionally, the plate fixing member is a setscrew threadedly connected to the plate fixture.

[0009] Optionally, the plate clamp uses an arc-shaped plate that matches the plate, and its inner arc surface is provided with an arc-shaped slot that matches the edge of the plate.

[0010] Optionally, rotating connection plates are provided at set positions on both clamping rods. A rotating shaft passes through the rotating connection plates of the two clamping rods, and the rotating connection plates are rotatably connected to the rotating shaft so that the two clamping rods are rotatably connected.

[0011] Optionally, the clamping rod is formed by sequentially connecting a plurality of rod portions, and an obtuse angle is provided between adjacent rod portions.

[0012] Optionally, a reinforcing rod is provided between adjacent rod portions.

[0013] In a second aspect, an embodiment of the present invention provides a working method for the electrolytic cell plate turning tooling described in the first aspect, including the following steps:

[0014] Connect one end of a sling to the top ends of both clamping rods through sling holes, and connect the other ends of the two slings to a lifting device;

[0015] Use the lifting device to lift the electrolytic cell plate turning tooling above the plate to be turned. Open the two clamping rods, and the lifting device drives the electrolytic cell plate turning tooling to move so that the two plate clamps are respectively located on both sides of the plate. The two clamping rods rotate until the plate clamps cooperate with the plate, and then use the plate fixing member to fix the plate clamp and the plate.

[0016] The lifting device lifts the electrolytic cell plate turning tooling and the plate to the plate turning height. Then, the plate clamp rotates to drive the plate to turn. The lifting device transports the turned plate to the target position, then loosens the plate fixing member and opens the clamping rod to complete the turning operation.

[0017] Optionally, the lengths of the two slings are the same.

[0018] Optionally, after installing a shackle at the sling hole, connect the shackle to the sling to achieve the connection between the sling and the clamping rod.

[0019] The beneficial effects of the present invention are as follows:

[0020] The electrolytic cell plate flipping tooling and working method of the present invention can clamp and fix the plate by using two clamping rods and a plate fixture, and can be connected to a lifting device through a sling hole. After the lifting device lifts the tooling and the plate to the flipping height, the plate can be flipped by driving the rotation of the plate fixture. Compared with the traditional flipping method that uses a plate lifting mechanism, a flipping mechanism, etc. in cooperation, only an ordinary lifting device is needed, and there is no need to use a magnetic adsorption type lifting device. Moreover, the flipping device is omitted, reducing equipment investment. And through the tooling, the lifting and flipping of the plate can be combined with each other, without lifting the plate to a special flipping device for flipping, reducing the number of times of plate handling. One lifting can complete the handling and flipping of the plate, greatly improving the operation efficiency, reducing the workload of the staff, and reducing the process time consumption.

[0029] Embodiment 1

[0030] This embodiment provides an electrolytic cell plate flipping tooling, as Figure 1 - Figure 2As shown in the figure, it includes two clamping rods 1 that are cross - arranged at set positions other than the ends. The axes of the two clamping rods 1 are located in two parallel planes. The two clamping rods 1 are rotatably connected at the cross - position so that the two clamping rods 1 form a clamping mechanism, and the two clamping rods 1 have two states: open and retracted.

[0031] Sling holes 2 are provided at the top ends of both clamping rods 1. The sling holes 2 can be connected to slings 3 to realize the connection between the entire tooling and the lifting equipment. Plate clamps 4 are provided at the bottom ends of both clamping rods 1. The plate clamps 4 are connected to the plate fixing parts, and the plate fixing parts are used to fix the plate 5 to the plate clamps 4. The plate clamps 4 are rotatably connected to the bottom ends of the clamping rods 1, and the plate clamps 4 can rotate, so as to realize the flipping of the plate 5.

[0032] The structures and shapes of the two clamping rods 1 are exactly the same, and both are composed of a plurality of rod segments connected in sequence. The adjacent rod segments are arranged at obtuse angles.

[0033] In this embodiment, as Figure 3 shown, the clamping rod 1 is composed of four rod segments, including a first rod segment 1 - 1, a second rod segment 1 - 2, a third rod segment 1 - 3, and a fourth rod segment 1 - 4 that are connected in sequence.

[0034] The first rod segment 1 - 1 and the second rod segment 1 - 2 are arranged at a first set obtuse angle, the second rod segment 1 - 2 and the third rod segment 1 - 3 are arranged at a second set obtuse angle, and the third rod segment 1 - 3 and the fourth rod segment 1 - 4 are arranged at a third set obtuse angle.

[0035] Among them, the first rod segment 1 - 1 and the third rod segment 1 - 3 are respectively located at both ends of the second rod segment 1 - 2, and the inclination directions of the first rod segment 1 - 1 and the third rod segment 1 - 3 relative to the second rod segment 1 - 2 are opposite.

[0036] The rotation connection position of the two clamping rods 1 is located on the second rod segment 1 - 2. The rotation connection position divides the second rod segment 1 - 2 into a first part and a second part. The length of the first part is less than the length of the second part. Among them, the sum of the lengths of the first rod segment 1 - 1 and the first part is less than the sum of the lengths of the second part, the third rod segment 1 - 3, and the fourth rod segment 1 - 4. The distance between the sling hole 2 and the rotation connection position is also less than the distance between the rotation connection position and the end of the fourth rod segment 1 - 4. By this means, in the natural state, the two clamping rods 1 are in the retracted state under the action of gravity.

[0037] Furthermore, in order to enhance the structural strength of the clamping rod 1, a reinforcing rod 6 is provided between the first rod segment 1 - 1 and the second rod segment 1 - 2, a reinforcing rod 6 is provided between the second rod segment 1 - 2 and the third rod segment 1 - 3, and a reinforcing rod 6 is provided between the third rod segment 1 - 3 and the fourth rod segment 1 - 4.

[0038] In this embodiment, rotating connection plates 7 are provided at the rotating connection positions of the two clamping rods 1. A rotating shaft passes through between the two rotating connection plates 7, and the rotating connection plates 7 are rotatably connected to the rotating shaft to achieve the rotational connection of the two clamping rods 1.

[0039] A sling hole 2 is provided at the top end of the clamping rod 1, and a plate electrode fixture 4 is rotatably connected to the bottom end. The structures and installation methods of the plate electrode fixtures at the bottoms of the two clamping plates 1 are exactly the same. Specifically, a connecting rod 8 is provided at the bottom end of the clamping rod 1. One end of the connecting rod 8 is fixedly connected to the bottom end of the clamping rod 1, and a rotating shaft is fixedly provided at the other end. The rotating shaft is rotatably connected to the plate electrode fixture 4 and can freely rotate around the rotating shaft. The plate electrode fixture 4 is rotatably connected to the clamping rod 1 through the rotating shaft.

[0040] The plate electrode fixture 4 is used to clamp and fix the plate electrode 5. In this embodiment, the plate electrode to be flipped is a circular plate electrode. Correspondingly, the plate electrode fixture 4 adopts an arc-shaped plate matching the plate electrode. An arc-shaped slot 9 matching the edge of the plate electrode is provided on the inner arc surface of the arc-shaped plate, and the edge of the plate electrode 5 can be inserted into the slot 9.

[0041] To prevent the plate electrode 5 from falling off the plate electrode fixture 4, a plate electrode fixing member is further provided on the plate electrode fixture 4. The plate electrode fixing member is used to fixedly connect the plate electrode 5 and the plate electrode fixture 4.

[0042] In this embodiment, the plate electrode fixing member is threadedly connected to the plate electrode fixture 4. Preferably, the plate electrode fixing member adopts a setscrew 10. The setscrew 10 is threadedly connected to the plate electrode fixture 4, and the axis of the setscrew 10 is perpendicular to the plate electrode 5 in the state of being clamped by the plate electrode fixture 4.

[0043] Furthermore, to ensure the stability of the fixation of the plate electrode 5 by the plate electrode fixture 4, a plurality of plate electrode fixing members are provided on the plate clamp 14. Preferably, two plate electrode fixing members are provided, and the two plate electrode fixing members are symmetrically arranged with respect to the center of the plate electrode fixture.

[0044] The setscrew 10 extends into the interior of the slot 9. After the edge of the plate electrode 5 is inserted into the slot 9, the setscrew 10 is rotated. The setscrew 10 can move along its own axis direction. After the setscrew 10 contacts the plate electrode 5, the setscrew 10 presses the plate electrode 5 against the groove surface of the slot 9, realizing the locking and fixation of the plate electrode 5 and the plate electrode fixture 4.

[0045] Embodiment 2

[0046] This embodiment provides a working method for the electrolytic cell plate electrode flipping tooling described in Embodiment 1, including the following steps:

[0047] Step 1: Take two shackles and install them at the sling holes 2 at the tops of the two clamping rods 1 respectively. At the same time, each shackle is connected to a sling 3. The lengths of the two slings 3 are the same, and the slings 3 are connected to the lifting equipment.

[0048] In this embodiment, an existing overhead crane can be used as the lifting device, and no detailed description will be given here. The sling 3 is connected to the hook of the overhead crane.

[0049] The connection between the lifting device and the flipping tooling is achieved through shackles and the sling 3.

[0050] Step 2: Use the overhead crane to lift the flipping tooling above the electrode 5 to be flipped, adjust the distance between the tooling and the electrode plate 5. Two operators respectively drive the clamping rods to rotate outward, and the two clamping rods 1 open. The lifting device drives the flipping tooling to move up and down, adjust the height of the electrode plate clamp 4. The staff rotates the clamping rod 1, uses the electrode plate clamp 4 to clamp the electrode plate, the edge of the electrode plate 5 is inserted into the slot 9, and then rotates the setscrew 10 so that the setscrew 10 locks and fixes the electrode plate 5 and the electrode plate clamp 4.

[0051] Step 3: After installing the flipping tooling, slowly lift the hook of the overhead crane. When the lifting height meets the flipping height of the electrode plate 5, and the overhead crane hoists the flipping tooling and the electrode plate 5 to the target position. In this embodiment, the target position is the position of the next process, as Figure 5 shown, the staff flips the electrode plate 5 so that the surface to be processed of the electrode plate 5 faces upward.

[0052] Step 4: Slowly lower the hook of the overhead crane. After the flipping tooling is not stressed in the vertical direction, that is, after the electrode plate 5 is completely placed at the target position, two staff members open the two clamping rods 1 to complete the flipping operation.

[0053] Compared with the traditional flipping method that uses an electrode plate lifting mechanism, a flipping mechanism, etc. in cooperation, by using the sling hole 2 and the sling 3, it can be directly connected to an ordinary lifting device. Therefore, an ordinary lifting device can be used as the lifting device, such as an overhead crane, etc., without using a magnetic lifting device, and the flipping device is omitted, reducing equipment investment. Moreover, through the tooling, the lifting and flipping of the electrode plate 5 can be combined with each other. There is no need to lift the electrode plate to a special flipping device for flipping. The electrode plate 5 can be directly lifted from the current process to the next process without passing through a flipping device, reducing the handling times of the electrode plate. One lifting can complete the handling and flipping processes of the electrode plate, greatly improving the operation efficiency, reducing the workload of the staff, and reducing the process time-consuming.

[0054] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
