Description

Technical Field

[0001] The present invention relates to the technical field of lifting appliances, and particularly to a lifting bayonet device for a washing machine balance ring brine bucket. Background Art

[0002] When a washing machine is dehydrating, the motor rotates at a high speed. If the clothes in the washing machine are unevenly placed, strong vibrations will occur and noises will be emitted. During the production process of the washing machine, brine needs to be injected into the balance ring to offset the resonance generated by the washing machine. In the production line of the washing machine, several buckets of brine are adjusted to the appropriate concentration for standby in each production shift. During production, the brine buckets are lifted by a crane to the injection platform at one end of the production line, the water outlet pipe is connected, and brine is injected into the balance ring. After the brine in the brine bucket is used up, the empty bucket is removed, and then the brine bucket with the adjusted concentration is lifted to the injection platform by the crane. In the existing production, a combination of a crane and manual lifting is adopted, but it is inevitable that brine will slosh out. Brine and brine vapor are corrosive and will damage the precision instrument equipment in the workshop. In view of the deficiencies of the existing technology, the present invention provides a lifting bayonet device for a washing machine balance ring brine bucket, which solves the problems raised in the background art. Summary of the Invention

[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: A lifting bayonet device for a washing machine balance ring brine bucket includes a hook, an upper hook plate, a lower hook plate, a force arm, a bayonet square pipe, a translation pulley, a bayonet block, a spring lock, a lock groove, upper and lower guide columns, and a cross beam; the hook is fixedly connected to the upper hook plate, the upper hook plate is connected to the cross beam through the force arm, a translation pulley is installed at the lower end of the force arm, and the translation pulley can move horizontally between the cross beam and the lower hook plate; there are upper and lower guide columns between the upper hook plate and the lower hook plate, the guide columns are fixedly connected to the lower hook plate, and the upper hook plate can move up and down along the guide columns; there is a spring lock and a lock groove design between the upper hook plate and the lower hook plate. When the upper hook plate descends and drives the spring lock to descend, the spring lock rotates 90 degrees horizontally after touching the lock groove to form a lock; the bayonet block and the bayonet square pipe are connected to one end of the force arm through a rotating shaft.

[0004] The upper hook plate is movably connected to the hook through bolts, which is convenient for disassembly.

[0005] Four holes are provided on the upper hook plate, and four guide columns are provided on the lower hook plate. The upper hook plate can move up and down along the guide columns.

[0006] A spring lock is provided below the upper hook plate. When it descends and touches the lock groove on the cross beam, it will rotate 90 degrees horizontally to form a lock.

[0007] A translation pulley is installed at the lower end of the force arm, and the translation pulley can move horizontally between the cross beam and the lower hook plate.

[0008] The bayonet block and the bayonet square tube are designed in parallel. The length of the bayonet square tube is slightly longer. When hoisting, it fits closely with the brine bucket, and the brine bucket will not sway left and right.

[0009] The two ends of the lower hook plate are designed with protruding long handles, which is convenient for manual operation during the hoisting process. Description of the Drawings

[0010] Figure 1 It is a three-dimensional external structure diagram of the present invention;

[0011] In the figure: 1, hook; 2, upper hook plate; 3, lower hook plate; 4, lever arm; 5, bayonet square tube; 6, translation pulley; 7, bayonet block; 8, spring lock; 9, lock groove; 10, upper and lower guide posts; 11, cross beam. Detailed Implementation Modes

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0013] First, hang the hook on the overhead crane and move it above the brine bucket so that the lower hook plate covers the brine bucket opening. Press the lever arm, and the two ends of the lever arm move outwards, so that the spring lock enters the lock groove and rotates horizontally by ninety degrees to form a lock. Hold the lower hook plate with your hand and pull up the hook. The two ends of the lever arm move inwards until the bayonet square tube and the bayonet block clamp the brine bucket opening. At this time, the overhead crane lifts the brine bucket and places it on the filling platform. Under the action of the spring, the two ends of the lever arm move outwards, and the bayonet square tube and the bayonet block loosen the brine bucket opening, completing this hoisting. Press the lever arm again to make the spring lock rotate horizontally by ninety degrees again and leave the lock groove for the next hoisting.

[0014] The above has described a detailed description of an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
