A slag unloading device for a shaft gantry crane

Abstract

The invention relates to the field of gantry cranes, in particular to a slag dumping device of a vertical well gantry crane. The slag dumping device comprises a feed cylinder used for bearing feed slags, a sealing part used for sealing the bottom of the feed cylinder, a blocking part used preventing a stone block from impacting the sealing part and a control part used for controlling the sealing part to open and close, the feed cylinder is vertically arranged, a connecting part is arranged at the top of the feed cylinder, the sealing part is located at the bottom of the feed cylinder, the topof the sealing part is hinged to and matched with the bottom of the feed cylinder, the blocking part is arranged at the portion, at the lower section of the feed cylinder, located above the sealing part, is fixedly connected with the feed cylinder and is internally provided with a cavity, the control part is located in the cavity, and one end of the control part is fixedly connected with the sealing part. An air cylinder drives an L-shaped support fixed to the output end of the air cylinder to move forwards to open or reset a first sealing plate, a second sealing plate and a third sealing plate to make the first sealing plate, the second sealing plate and the third sealing plate seal one end of the feed cylinder to achieve automatic unloading.

Description

technical field [0001] The invention relates to the field of gantry cranes, in particular to a slag unloading device of a shaft gantry crane. Background technique [0002] There are basically two types of buckets used in the construction of the vertical shaft gantry crane: round buckets or square buckets. When using buckets, a hinge switch is usually designed at the bottom of the bucket, and the bottom is opened manually after being lifted to the bucket table. The switch unloads the ballast, and the ballast discharge process is: load the ballast→lift the ballast bucket (bucket)→translate the ballast bucket (bucket) to the ballast discharge table→manually open the bottom switch→translate and lift the ballast. From the above working process, it can be seen that the traditional The gantry crane has the following deficiencies: (1) Due to unloading the muck from the bottom of the muck bucket (bucket), the movable door at the bottom of the dreg bucket (bucket) has been hit by ston...

[0002] There are basically two types of buckets used in the construction of the vertical shaft gantry crane: round buckets or square buckets. When using buckets, a hinge switch is usually designed at the bottom of the bucket, and the bottom is opened manually after being lifted to the bucket table. The switch unloads the ballast, and the ballast discharge process is: load the ballast→lift the ballast bucket (bucket)→translate the ballast bucket (bucket) to the ballast discharge table→manually open the bottom switch→translate and lift the ballast. From the above working process, it can be seen that the traditional The gantry crane has the following deficiencies: (1) Due to unloading the muck from the bottom of the muck bucket (bucket), the movable door at the bottom of the dreg bucket (bucket) has been hit by stones for a long time, resulting in deformation and poor closure. Small and medium-sized ballast leaks from the bottom, posing safety hazards; (2) The ballast bucket (bucket) is only suitable for lifting small weight (volume) ballast. If the ballast is too heavy, it will directly damage the bottom hinge of the ballast bucket (bucket) , so that it cannot be fastened with the switch; (3) This kind of operation method needs to be specially equipped with 2 people to switch and unload the ballast door on the ballast platform.
