Description

Technical Field

[0001] The utility model relates to the technical field of loaders, in particular to a steel shell structure suitable for a loader to be filled with a counterweight. Background Art

[0002] At present, loader counterweights are divided into integral cast iron counterweights and steel shell filled counterweights. Integral cast iron counterweights can be made into more complex shapes with beautiful appearance, but they use a large amount of steel, which consumes iron resources and increases smelting pollution, resulting in high costs. The steel shell mass of steel shell filled counterweights is only about 1 / 3 to 1 / 4 of the total mass of the counterweight, which greatly reduces the amount of steel used, so it is low in cost and environmentally friendly. At present, most domestic loaders use steel shell filled counterweights.

[0003] However, in the prior art, most traditional loader counterweights are integral and fixed, so the weight of the counterweight cannot be changed. Therefore, the loader cannot flexibly adjust the counterweight position according to different work requirements, thereby reducing the work efficiency of the loader. At the same time, collisions are inevitable when the loader is working, and if the impact force cannot be reduced during the collision, the mechanical parts of the loader will be damaged, causing economic losses.

[0038] The bottom of the counterweight block 34 is slidably connected to the outer wall of the roller 31, the bottom of the fixed block 36 is fixedly connected to the top of the side shell 5, the bottom of the fixed plate 33 is fixedly connected to the top of the side shell 5, the anti-collision mechanism 4 includes a connecting block 41, the inner wall of the connecting block 41 is slidably connected with an anti-collision shell 43, the inner wall of the anti-collision shell 43 is threaded with a lifting ear 44, the outside of the connecting block 41 is provided with a collapse shell 45, and the anti-collision shell 43 slides in the slide groove 42 through a slider.

[0039] A sliding groove 42 is opened in the wall of the connecting block 41, and a connecting strip 46 is fixedly connected to the outer wall of the crush shell 45, and is linearly arrayed along the outer wall of the crush shell 45. The outer wall of the connecting block 41 is fixedly connected to the outer wall of the side shell 5, and the outer wall of the connecting strip 46 is fixedly connected to the inner wall of the anti-collision shell 43. The inner wall of the crush shell 45 is fixedly connected to a supporting block 47, and is linearly arrayed along the inner wall of the crush shell 45. A threaded hole is opened on the anti-collision shell 43 to facilitate the lifting ear 44 to be screwed in to lift the anti-collision shell 43.

[0040] Working principle:

[0041] When in use, first fill the shell 1 and the bottom shell 6 with counterweights. After the counterweights are filled, insert the fixed shell 2 on the shell 1 into the loader, and install the shell 1 on the loader. After the shell 1 is completed, the anti-collision mechanism 4 is simultaneously installed on the side shell 5. The side shell 5 is also filled with counterweights. Hook it to the lifting ear 44 through the lifting equipment, lift the anti-collision mechanism 4, and slide the slider in the anti-collision mechanism 4 into the slide groove 42 on the connecting block 41.

[0042] The connecting block 41 is fixed on the side shell 5, so the anti-collision mechanism 4 can be fixed on the side shell 5. After the anti-collision mechanism 4 is installed, the lifting ear 44 is removed. At this time, the anti-collision mechanism 4 can perform anti-collision work. When the loader hits the wall, the anti-collision shell 43 first contacts the wall and deforms to offset part of the impact force. Under the continuous action of the impact force, the collapse shell 45 connected to the anti-collision shell 43 through the connecting strip 46 is deformed synchronously under the impact force and offsets part of the impact force again. A support block 47 is provided in the collapse shell 45. Therefore, with the support of the support block 47, the strength of the collapse shell 45 can be increased.

[0043] When the loader is working, the position of the counterweight 34 can be changed by adjusting the mechanism 3 according to different working requirements and load conditions. At this time, the active tooth 38 on the fixed block 36 is rotated to force the active tooth 38 to drive the driven tooth 37 to rotate synchronously, and a groove 32 is provided on the side shell 5 so that the side shell 5 will not block the rotation of the driven tooth 37. The driven tooth 37 is fixed on the screw rod 35, and the screw rod 35 is threadedly connected to the counterweight 34. Therefore, under the rotation of the screw rod 35, the counterweight 34 is forced to slide on the roller 31 along the screw rod 35, and because of the rolling of the roller 31, the friction at the bottom of the counterweight 34 is reduced, and a fixed plate 33 is connected to the end of the screw rod 35 away from the driven tooth 37, so that the rotation of the screw rod 35 is supported.

[0044] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
