The top of the pawl 300 is provided with a bearing surface 310, when the pawl 300 is not subjected to external force, the steel wire rope 230 is in a straightened state, and the bearing surface 310 is in a horizontal state; the pawl 300 is made of elastic rubber, and when the bottom baffle 110 of the lifting container 100 is retracted and pressed on the bearing surface 310, the pawl 300 can be bent to generate elastic deformation; the lower end of the pawl 300 is hinged with the hinge support 210, the steel wire rope 230 is fixed at the middle part of the pawl 300, the pressure spring mechanism 220 is fixed at the lower part of the pawl 300, and the length of the steel wire rope 230 is longer than the distance from the lower end of the pawl 300 to the vertical rail 200, so that the top end of the pawl 300 is inclined towards the lifting container 100.
The technical scheme provided by the embodiment of the application at least has the following technical effects or advantages:
In the embodiment, by arranging the elastic pawl 300, when the chain for pulling the lifting container 100 upwards is broken or power is off to cause the lifting container 100 to stall and fall, the bearing surface 310 of the pawl 300 supports the lifting container 100, the bottom edge of the lifting container 100 collides with the bearing surface 310 of the pawl 300, the pawl 300 bends under the pressure action of the lifting container 100, the pawl 300 after bending deformation buffers the collision, and the damage of hard impact to the lifting container 100 is reduced; secondly, the top of the pawl 300 is inclined from the vertical rail 200 to one side of the lifting container 100, and the middle part of the pawl 300 is bent and raised towards the vertical rail 200 after the bearing surface 310 is pressed due to the limitation of the compression spring mechanism 220 and the hinge support 210 to the bottom of the pawl 300, as shown in fig. 2, so that the tensile force applied by the steel wire rope 230 is weakened; therefore, the bending of the pawl 300 simultaneously relieves the hard impact suffered by the steel wire rope 230 and the bottom of the lifting container 100, thereby solving the technical problems that the lifting container 100 in the prior art is easy to fall down and the falling is easy to generate collision injury when being stopped, and realizing the technical effect of reducing the risk of collision damage after the falling of the container.
Example two
Considering that the pawl 300 in the first embodiment is made of elastic rubber, although the pawl 300 can generate elastic deformation to buffer the impact force when the lifting container 100 falls down, so as to protect the buffer container from damage, when the weight of the feed raw material loaded in the lifting container 100 is large, the pawl 300 may be excessively bent and deformed to be separated from two sides of the lifting container 100, so that the lifting container 100 falls down again, and meanwhile, the pawl 300 excessively bent may be damaged, so that the device needs to be improved, as shown in fig. 3 and 4, the specific structure is as follows:
the pawl 300 is internally provided with a shape control cavity 340, the shape control cavity 340 is a columnar cavity, the length direction of the shape control cavity 340 is parallel to the length direction of the pawl 300, the shape control cavity 340 is internally provided with a limited plate 341, the limited plate 341 is hard columnar, the limited plate 341 and the shape control cavity 340 are coaxially arranged, a plurality of limited plates 341 are propped against each other from head to tail along the length direction of the shape control cavity 340; the limiting plate 341 in the control chamber 340 provides upward support to the pawl 300 when the lift container 100 impacts the load bearing surface 310 downward.
The axial line of the shape control cavity 340 in the length direction is parallel to the side surface of the pawl 300 near to the side of the vertical rail 200, so that the length direction of the shape control cavity 340 is not perpendicular to the bearing surface 310, and the plurality of limiting plates 341 are inclined to one side to be arranged in an arc shape after being pressurized, thereby preventing the limiting plates 341 from excessively straightening and completely reacting the impact force to the bottom of the lifting container 100.
The technical scheme provided by the embodiment of the application at least has the following technical effects or advantages:
In this embodiment, by providing the shape control cavity 340 and the limiting plates 341, when the lifting container 100 impacts the pawl 300 downwards, after the pawl 300 is bent to generate elastic deformation, the length of the single limiting plate 341 in the shape control cavity 340 limits the overall bending degree of the pawl 300, so that the pawl 300 has stronger supporting force on the lifting container 100, and meanwhile, the pawl 300 cannot be excessively bent to cause the lifting container 100 to be separated from the pawl 300.
Example III
Considering that, in the second embodiment, after the load bearing surface 310 of the pawl 300 is impacted, the pawl 300 is bent, and although the bending degree of the pawl 300 is limited by the limiting plates 341, the impact force applied to the pawl 300 in the moment when bending is strong, the plurality of limiting plates 341 are immediately bent to the side of the lifting container 100, and the limiting plates 341 abut against each other, so that collision friction is caused, and the limiting plates 341 are easily damaged. Secondly, the shape and length of the limiting plate 341 are fixed, and when different amounts of materials are contained in the lifting container 100, the pawl 300 receives different impact forces, and the supporting degree of the pawl 300 to the lifting container 100 is different, so that the buffering speed of the lifting container 100 is also different. When the supporting force is too large and the weight of the lifting container 100 is small, the buffer is insufficient, so that the granular material in the lifting container 100 flies after being impacted, when the supporting force is too small and the weight of the lifting container 100 is large, the supporting force is insufficient, and the limiting plate 341 and the pawl 300 are easily damaged, so that the device needs to be improved, as shown in fig. 5 and 6, the specific structure is as follows:
The bottom of the bearing surface 310 is provided with a horizontally arranged stress cavity 350, a transmission channel 360 is arranged between the stress cavity 350 and the shape control cavity 340, the transmission channel 360 communicates the stress cavity 350 with the shape control cavity 340, one side of the bottom of the shape control cavity 340 is provided with a pressure stabilizing hole 370, and the pressure stabilizing hole 370 is communicated with an external space.

S3: the heating plate 400 heats the heat exchange liquid, the temperature of which rises to soften the paraffin 500, and the pawl 300 starts to bend secondarily after the paraffin 500 is softened.

Example five
