Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum electrolytic graphitized carbon blocks, and in particular relates to a graphitized carbon block loading and unloading furnace hanging device. Background Art

[0002] Graphitized carbon blocks are used as electrodes in the aluminum electrolysis production process. The electrodes are divided into cathodes and anodes. Since the electrolysis process requires that the electrodes are all in the shape of a rectangular parallelepiped, and the sizes of electrodes in different electrolytic cell series are different, there is no safer and more unified clamping tool to lift and move the graphitized carbon blocks during the production process. The anode carbon blocks have a single outer size and are lifted and moved by special clamping slings. At present, most of the domestic cathode carbon block production units use wire ropes or chains to lift and move the cathode carbon blocks.

[0003] When using steel wire ropes to hoist and move cathode carbon blocks, the steel wire ropes wear out quickly, so the steel wire ropes need to be replaced frequently, and the production cost is high. At the same time, there are safety risks when using broken wires and strands of steel wire ropes. When using chains to hoist and move cathode carbon blocks, the cathode carbon blocks are easy to slip and fall when they are lifted in an unlocked state, which also poses a greater risk of use. Existing hoisting tools have obvious shortcomings during use, so there is an urgent need for a special hoisting tool to assist in the production of graphitized carbon blocks. Utility Model Content

[0004] The embodiment of the present application provides a graphitized carbon block loading and unloading lifting device, which solves the problem of high safety risk factor and easy falling off of carbon blocks when they are hoisted.

[0005] In a first aspect, a graphitized carbon block loading and unloading furnace hanging device is characterized by comprising: a connecting rod mechanism, a clamping mechanism and an automatic locking mechanism;

[0006] The connecting rod mechanism comprises a left connecting rod and a right connecting rod, wherein the left connecting rod and the right connecting rod are formed by a plurality of connecting rods being hingedly connected by a connecting shaft, and the left connecting rod and the right connecting rod have the same structure and are arranged symmetrically to each other; the connecting rod mechanism is used to convert the upward pulling force into a lateral clamping force;

[0007] The clamping mechanism comprises a left clamping part and a right clamping part, the left clamping part and the right clamping part have the same structure and are symmetrically arranged, and the clamping part is hinged to the bottom of the connecting rod mechanism through a connecting shaft; the clamping mechanism is used to convert the lateral clamping force into an upward pulling force to clamp the clamped object and prevent it from falling;

[0008] The automatic locking mechanism is hinged with the connecting rod mechanism by connecting the rotating shaft, and is used to realize automatic locking of the connecting rod mechanism when clamping an object, thereby realizing locking of the clamping mechanism; the automatic locking mechanism includes: a gear rack mechanism and a ratchet mechanism; wherein the gear rack mechanism includes a gear and a rack, and the gear and the rack are meshed; the ratchet mechanism includes two sets of ratchets and pawls, and the two sets of ratchets and pawls are arranged opposite to each other on the left and right sides; the gear of the gear rack mechanism is connected to the ratchet of the ratchet mechanism through the same rotating shaft; the gear rack mechanism is used to convert the up and down linear motion of the rack into the rotation of the gear around the axis, and the ratchet is driven to rotate by the gear, and the two sets of pawls rotate bidirectionally with the ratchet to realize locking of the automatic locking mechanism;

[0009] The connecting rod mechanism drives the clamping mechanism to move so as to clamp the object, and at the same time drives the automatic locking mechanism to move, thereby achieving clamping and locking of the object by the clamping mechanism.

[0010] In another possible implementation, the clamping portion of the clamping mechanism further includes a clamping plate and a clamping plate bracket, the clamping plate and the clamping plate bracket are hinged via a connecting shaft, and the clamping plate can rotate around the central axis of the shaft.

[0012] In another possible implementation, the graphitized carbon block loading and unloading hanger device also includes a hanging point bracket, which is hinged to the top of the connecting rod mechanism through a connecting shaft, and is used to provide a hanging point for the hook during the hanging operation.

[0013] The present invention lifts the upper end of the connecting rod mechanism through the lifting equipment, and the connecting rod mechanism converts the upward pulling force it receives into a lateral supporting force. The clamping mechanism converts the lateral clamping force applied by the connecting rod mechanism into an upward pulling force to clamp the object, and at the same time drives the automatic locking mechanism to move to realize the locking function, thereby realizing the automatic locking of the object.

[0021] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0022] In the description of the present application, the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0023] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a conflicting connection or an integrated connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] Figure 1 This is a schematic diagram of the structure and working state of a graphitized carbon block loading and unloading furnace lifting device provided in the embodiment of the present application. Figure 1 The graphitized carbon block 40, the lifting hook 50 and the lifting point bracket 60 are shown in the figure. It should be understood that the graphitized carbon block 40, the lifting hook 50 and the lifting point bracket 60 do not belong to the structure of the graphitized carbon block loading and unloading furnace lifting device.

[0025] like Figure 1 As shown, the graphitized carbon block loading and unloading furnace lifting device includes: a connecting rod mechanism 30, a clamping mechanism 10 and an automatic locking mechanism 20.

[0026] The connecting rod mechanism 30 includes a left connecting rod and a right connecting rod, and the left connecting rod and the right connecting rod are both formed by a plurality of connecting rods 31 connected by a connecting shaft 32 (see Figure 2 ), the left connecting rod and the right connecting rod have the same structure and are arranged symmetrically; the connecting rod mechanism 30 is used to convert the upward pulling force into a lateral clamping force; the clamping mechanism 10 includes a left clamping part and a right clamping part, the left clamping part and the right clamping part have the same structure and are arranged symmetrically, the left clamping part and the right clamping part are respectively hinged to the bottom of the left connecting rod and the right connecting rod of the connecting rod mechanism 30 through the connecting shaft 32 to receive the lateral clamping force transmitted to them by the connecting rod mechanism 30, so that the left clamping part and the right clamping part are mutually clamped. The automatic locking mechanism 20 is hinged to the connecting rod mechanism 30 via a connecting shaft, and is used to automatically lock the connecting rod mechanism 30 when clamping the object, thereby locking the clamping mechanism 10; the clamping mechanism 10 is driven by the connecting rod mechanism 30 to move, thereby clamping the object and driving the automatic locking mechanism 20 to move, thereby clamping and locking the object by the clamping mechanism 10.

[0027] Figure 3 A schematic diagram of the structure of an automatic locking mechanism provided in an embodiment of the present application.

[0028] like Figure 3 As shown, the automatic locking mechanism 20 includes a gear rack mechanism and a ratchet mechanism.

[0029] The gear rack mechanism includes a gear 24 and a rack 21 (see Figure 4 ), the gear 24 and the rack 21 are meshed; the ratchet mechanism includes two groups of ratchets 22 and pawls 23, and the left and right groups of ratchets 22 and pawls 23 are arranged opposite to each other on the left and right sides; the gear 24 of the gear and rack mechanism is connected to the ratchet 22 of the ratchet mechanism through the same rotating shaft; the gear and rack mechanism is used to convert the up and down linear motion of the rack 21 into the axial rotation of the gear 24, and the ratchet 22 is driven to rotate by the gear 24. The two groups of pawls 23 can rotate bidirectionally with the ratchet 22, respectively playing the upward and downward locking functions to prevent the ratchet 22 from rotating in the opposite direction.

[0030] During the lifting operation, the above-mentioned automatic locking mechanism is stretched up and down by the connecting rod mechanism, and at the same time, the rack in the automatic locking mechanism makes up and down linear motion, the rack drives the gear, the gear drives the ratchet to rotate, and the ratchet simultaneously drives one of the sets of pawls, which will reversely lock the ratchet to prevent the ratchet from rotating in the opposite direction, and lock the rack and gear mechanism, the connecting rod mechanism, and the clamping mechanism in turn, thereby preventing the clamped object from falling during the lifting operation.

[0031] For example, during the lifting operation, the connecting rod mechanism stretches, driving the rack to move upward, and at the same time driving the gear to rotate clockwise, the gear drives the ratchet to rotate clockwise, and at the same time the ratchet drives a group of pawls that can rotate clockwise, and the group of pawls locks the ratchet in the counterclockwise direction to prevent the ratchet from rotating counterclockwise, and sequentially locks the rack and gear mechanism, the connecting rod mechanism, and the clamping mechanism, thereby preventing the left and right clamping parts of the clamping mechanism from opening, thereby preventing the clamped object from falling during the lifting operation; when the clamped object is removed, the pawl can be opened to unlock the automatic locking mechanism, Open the left and right clamping parts of the clamping mechanism; during the lifting operation, the connecting rod mechanism contracts, driving the rack to move downward, and at the same time driving the gear to rotate counterclockwise, the gear drives the ratchet to rotate counterclockwise, and at the same time the ratchet drives one of the sets of pawls that can rotate counterclockwise, and this set of pawls locks the ratchet in a clockwise direction to prevent the ratchet from rotating clockwise, and locks the rack and gear mechanism, the connecting rod mechanism, and the clamping mechanism in turn, thereby preventing the left and right clamping parts of the clamping mechanism from closing; when you want to clamp an object, you can open the pawl, unlock the automatic locking mechanism, and close the left and right clamping parts of the clamping mechanism.

[0032] It is understandable that the clamped object is not limited to the graphitized carbon block, but may also be other objects whose shapes and sizes are compatible with the size of the clamping mechanism.

[0033] The graphitized carbon block loading and unloading furnace lifting device in the embodiment of the present application can realize the grasping and releasing of objects, and during the lifting process, the grasped objects are not easy to fall due to the automatic locking mechanism of the automatic locking mechanism.

[0034] In another embodiment, the graphitized carbon block loading and unloading furnace lifting device also includes a lifting point bracket 60, which is hinged to the top of the connecting rod mechanism 30 through a connecting shaft, so that the left connecting rod and the right connecting rod of the connecting rod mechanism 30 are connected together, which is used to provide a lifting point for the hook during the lifting operation.

[0035] In one embodiment, the automatic locking mechanism 20 further includes a gear support 25 and a rack support 26 (see Figure 4 ), wherein the gear bracket 25 is used to connect the gear 24, the ratchet 22 and the connecting rod mechanism 30 together, and the connection method is hinged through a connecting shaft; the rack bracket 26 is used to connect the rack 21 and the connecting rod mechanism 30 together, and the connection method is hinged through a connecting shaft.

[0036] It is easy to understand that the connection portion between the gear bracket 26 and the rack 21 can be located at the top, so as to reserve a longer working distance for the rack during the lifting operation.

[0037] It should be noted that the automatic locking mechanism is not limited to the rack and pinion mechanism and the ratchet mechanism, but can also be other devices that achieve automatic locking, such as: electric brake. Among them, the motor brake is mainly composed of two parts: the brake coil and the brake friction pad. When the connecting rod mechanism is moving forward, the motor operates normally, the brake coil is energized to generate a magnetic field, which attracts the brake friction pad away from the motor shaft, and the motor can rotate freely. When the clamping mechanism locks the clamped object, the motor stops working, the brake coil is de-energized, the magnetic field disappears, and the brake spring presses the brake friction pad to the motor shaft, quickly braking the motor through friction to achieve a quick stop.

[0038] Figure 6 A schematic diagram of the structure of a clamping mechanism provided in an embodiment of the present application.

[0039] like Figure 6 As shown, the clamping mechanism 10 comprises: a clamping plate 13 and a clamping bracket 11. The clamping plate 13 and the clamping plate bracket 11 are hingedly connected by a connecting shaft 12, and the clamping plate can rotate around the central axis of the shaft.

[0040] It is easy to understand that the clamping plate 13 and the clamping plate bracket 11 can be connected in a hinged manner to freely adjust the placement state of the object when clamping the object. Specifically, for example, the clamped object is a rectangular charcoal block, which is placed horizontally when clamped. When it is placed at the target position during the lifting operation, the charcoal block can be placed vertically by rotating the clamping plate and the clamping plate bracket; the charcoal block is placed vertically when clamped. When it is placed at the target position during the lifting operation, the charcoal block can be placed horizontally by rotating the clamping plate and the clamping plate bracket.

[0041] In another embodiment, the surface of the clamping plate 13 has anti-slip bumps (such as Figure 6 As shown in the figure, the shape of the protrusion is not limited. It is easy to understand that the anti-slip protrusion can increase the friction between the clamping plate and the clamped object, ensuring that the clamped object is not likely to fall during the clamping process.

[0042] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and do not limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
