Description

Technical Field

[0001] The present application relates to the technical field of electrolysis equipment, and in particular to a gantry crane for transferring a plate. Background Art

[0002] In the electrolysis industry such as manganese dioxide, the manganese sulfate solution is mainly electrolyzed by the pole plate to precipitate manganese dioxide on the pole plate. After the electrolysis is completed, the pole plate is lifted out of the electrolytic cell by the crane and placed on the rack. After the electrolyte is drained, the pole plate is hit manually or by equipment to make the manganese dioxide on the pole plate fall off, so as to facilitate rinsing and other operations. The beaten pole plate can be recycled after treatment. The pole plate is mainly transferred by a gantry crane to move it between the various processes. For example, a Chinese patent with application number 202020869928.4 discloses an electrolytic plate hoist, including a door-shaped frame straddling the aisles at both ends of the electrolytic cell, and rollers rolling along the aisle are arranged under the two vertical poles of the door-shaped frame. The crossbeam of the door-shaped frame is provided with an electric hoist that moves along its length, and a hook made of insulating material for lifting the upper cross bar of the pole plate is suspended under the electric hoist. When the door frame of the device starts or stops, the hook under the electric hoist and the plate will shake due to inertia, and the plate needs to be manually supported to stop it quickly. Secondly, when using the automatic stripping device to hit the plate, the lifting device of the lifting equipment can only shake slightly. The existing lifting equipment only uses a flexible rope to lift, which cannot meet the requirements of plate transportation and automatic stripping equipment. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a plate transfer gantry crane, which limits the large-scale shaking of the plate through the guide rod, and at the same time, an elastic plate is provided on the lifting device to allow the plate to shake slightly, so as to reduce the impact of the impact force on the gantry crane when the plate is automatically peeled off and hit.

Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them.

If the specific posture changes, the directional indication will also change accordingly.

[0024] In addition, the descriptions of "first", "second", etc. in this application are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0025] like Figures 1 to 3 As shown, an embodiment of the utility model provides a plate transfer gantry crane, comprising: a main frame 1, the lower part of the main frame 1 is installed on the guide rail through rollers, the main frame 1 is a door-shaped structure, and the upper part of the main frame 1 is provided with a sub-frame 4; a winch 2, the winch 2 is installed on the upper part of the sub-frame 4; a sling 3, the sling 3 is connected to the rope on the winch 2 through a movable pulley 5; a guide rod 6, the lower end of the guide rod 6 is connected to the sling 3 through a hinge assembly, and the upper part of the guide rod 6 is slidably connected to the main frame 1 through a sleeve 7; wherein, there are two guide rods 6, the two guide rods 6 are installed in parallel on the main frame 1, and the guide rods 6 are connected to both sides of the sling 3.

[0026] When using a gantry crane to lift the pole plate, the pole plate is connected to the sling 3 through the hook 15, and then the winch 2 is started. After the rope is pulled up, the movable pulley 5 drives the sling 3 and the guide rod 6 to move upward, so as to lift the pole plate. The driving motor arranged at the lower part of the main frame 1 drives the roller to drive the main frame 1 to move on the guide rail. When the main frame 1 starts or stops, the sling 3 is prone to swing due to inertia. For this reason, the device is provided with a guide rod 6, and the guide rod 6 is limited by the sleeve 7 so that the guide rod 6 can only slide axially, and the guide rod 6 has high hardness and is not easy to swing. The lower end of the guide rod 6 is connected to the sling 3 through the hinge assembly. When the pole plate pulls the sling 3 to swing, due to the short length of the hinge assembly, the swing amplitude of the pole plate is small, and the pole plate can stop quickly.

[0027] When it is necessary to use a gantry crane to place the electrode plate into the automatic stripping equipment for automatic stripping, the automatic stripping uses a high-speed rotating hammer to hit the electrode plate to make the attachments on the electrode plate fall off. When the hammer hits the electrode plate, the electrode plate will vibrate. At this time, the hanger 3 is restricted by the hinge assembly and the spring 13. The hanger 3 can swing slightly to prevent the vibration of the electrode plate from being directly transmitted to the main frame 1 through the guide rod 6, thereby reducing the impact of vibration on the lifting equipment.

[0028] In a preferred embodiment, the hinge assembly includes a first hinge member 8, a second hinge member 9, and a third hinge member 10. The first hinge member 8 is connected to the lower end of the guide rod 6, the third hinge member 10 is connected to the hanger 3, the upper part of the second hinge member 9 is hinged to the first hinge member 8 through a first shaft 11, and the lower part of the second hinge member 9 is hinged to the third hinge member 10 through a second shaft 12. The length of the first hinge member 8, the second hinge member 9, and the third hinge member 10 is 10 cm to 15 cm, which is relatively short, and the swing direction is limited by the shaft, so that the hanger 3 can only swing slightly, meeting the use requirements when transferring the plate.

[0029] In a specific embodiment, the axis of the first shaft 11 is in the same direction as the guide rail, the axis of the second shaft 12 is perpendicular to the axis of the first shaft 11, and the long direction of the sling 3 is parallel to the axis of the second shaft 12, so that the sling 3 can swing in two planes under the limitation of the shaft.

[0030] In a preferred embodiment, a spring sheet 13 is provided between the guide rod 6 and the hanger 3, and the two ends of the spring sheet 13 are respectively hinged to the guide rod 6 and the hanger 3 through a third shaft 14, and the axis of the third shaft 14 is parallel to the first shaft 11. When the hanger 3 swings, a reaction force is provided by the twisting of the spring sheet 13 to limit the swinging of the hanger 3 and the electrode plate. The spring sheet 13 is a flat structure, which is easier to twist in the flat direction than in the wide direction. Therefore, the hanger 3 can swing to a certain extent in the front and rear directions of travel, and the swing amplitude is smaller in the left and right directions of travel, which meets the requirements for the swing amplitude of the electrode plate when the electrode plate is moved and the automatic stripping equipment is used.

[0031] The hanger 3 can swing at the lower end of the guide rod 6 under the constraint of the hinge assembly and the spring 13. This is mainly because the spring 13 can bend elastically and secondly because some gaps are left in the assembly of each hinge. The hanger 3 can swing slightly due to the above two reasons. When moving, the pole plate and the hanger 3 can be quickly stopped from shaking. When using automatic stripping equipment, the swinging can reduce the impact of vibration on the lifting equipment.

[0032] In a preferred embodiment, hooks 15 are symmetrically arranged at the lower part of the hanger 3 to facilitate the connection between the hanger 3 and the pole plate.

[0033] In a preferred embodiment, the sub-frame 4 is connected to the upper portion of the sleeve 7 to improve the stability of the sleeve 7 .

[0034] Preferably, a reflector 17 is provided at the lower end of the guide rod 6, and a laser rangefinder 16 is provided under the main frame 1. The laser emitted by the laser rangefinder 16 is parallel to the guide rod 6, and the laser is projected onto the reflector 17. The laser rangefinder 16 provides a distance signal to the controller of the starting device to facilitate the control of the lifting distance.

[0035] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
