Abstract
The utility model discloses an improvement for a cylinder piston of a transshipment grab bucket. The cylinder piston of the transshipment grab bucket mainly comprises a piston body, a clamping ring, a leather cup, a support ring, a leather cup shoulder, a ring-shaped groove, fastening leather cup thread holes and a fastening screw, characterized in that a cylinder with a big groove is arranged at the upper portion of the piston body and the leather cup shoulder is arranged at two surface of the periphery of the cylinder, the upper and lower surfaces at the central section of the leather cup shoulder are provided with six to eight fastening leather cup thread holes, the ring-shaped groove is arranged on the center line of the cross section of the piston, the shape of the leather cup section is in a semi-bow type and the bore is equal to the diameter of the circle at the inner side of the leather cup shoulder on the piston body, the cylindrical diameter is equal to the cylindrical diameter of the leather cup shoulder on the piston body, the bottom of the leather cup is uniformly distributed six to eight circular holes, the shape and size of the support ring are the same as the ring-shaped groove and the support ring is made of abrasion resistant nylon. According to the utility model, the structure of the piston is improved, the damaged position is transferred thus the cylinder scraped times are greatly reduced, the maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of mine transferring equipment, is particularly useful for the transfer grab bucket equipment in the mine vertical shaft construction.
Technical background
At present, the subject matter that the transferring equipment of using in mine construction exists is that transfer grab bucket cylinder piston is scraped the cylinder problem, if in a single day it is not steady the cylinder body operation to occur, transfer grab bucket cylinder piston very easily takes place scrape the cylinder problem, cause long-time maintenance, increase expense, influence manufacturing schedule.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and transfer grab bucket cylinder piston very easily takes place in solution scrapes the cylinder problem, and a kind of transfer grab bucket cylinder piston is provided.
The technical scheme in the invention for solving the technical problem is:
Form by piston body, trim ring, leather cup, support ring, leather cup shoulder, ring groove, fastening leather cup tapped hole, fastening screw trip bolt.Its piston body periphery two sides of the cylinder bodily form that piston body is big groove up and down is provided with the leather cup shoulder, each uniform individual fastening leather cup tapped hole of 6-8 that is provided with of the middle part upper and lower surface of leather cup shoulder, the center line of piston body transverse section surface is provided with ring groove, the leather cup section configuration is that half bowl-type diameter of bore equals the inboard circular diameter of leather cup shoulder on the piston body, outside diameter equals the outside diameter of leather cup shoulder on the piston body, uniformly on the leather cup bottom center line be provided with 6-8 circular hole, the trim ring section configuration is that half bowl-type diameter of bore equals the inboard circular diameter of leather cup shoulder on the piston body with the section configuration of leather cup, uniformly on the trim ring bottom center line be provided with 6-8 circular hole, the trim ring external diameter is less than leather cup section thickness of leather cup external diameter, and the big light section of shape that the shape size of support ring equals ring groove is that its material of rectangle is designed to wear resistant nylon.
The technical scheme in the invention for solving the technical problem can also be:
Leather cup shoulder two sides connects leather cup, trim ring and fastening screw trip bolt successively respectively, with fastening screw trip bolt trim ring, leather cup is anchored in the fastening leather cup tapped hole on the piston body.
The beneficial effects of the utility model are:
The utility model has shifted damaged part by improving structure of piston, has significantly reduced and has scraped the cylinder phenomenon, has reduced maintenance cost.
Description of drawings
Fig. 1 is piston and cylinder body schematic representation
Fig. 2 is the piston body schematic representation
Fig. 3 is piston and the cylinder body schematic representation before improving
Fig. 4 is the piston body schematic representation before improving
Among the figure mainly by 1 piston body, 2 trim rings, 3 leather cups, 4 support rings, 5 leather cup shoulders, 6 ring grooves, 7 fastening leather cup tapped holes, 8 fastening screw trip bolts.
Embodiment
Fig. 3 and Fig. 4 are piston and the cylinder body schematic representation before improving, and are made up of 1 spacer ring, 2 trim rings, 3 pistons, 4 leather cups.When grab bucket works together, cooperate motion to axial with inboard wall of cylinder block by leather cup 4, but if cylinder body work is not steady, after adding that leather cup 4 wears out, can cause spacer ring 1 to collide mutually with inboard wall of cylinder block, the spacer ring material is Q235, cause the scratch casing wall, when continuing operation again, air pressure can occur and reduce, problems such as grab bucket opening and closing difficulty.
Fig. 1 and Fig. 2 are piston and the cylinder body schematic representation after improving, and 1 piston body, 2 trim rings, 3 leather cups, 4 support rings, 5 leather cup shoulders, 6 ring grooves, 7 fastening leather cup tapped holes, 8 fastening screw trip bolts are formed.Its peripheral two sides of the cylinder bodily form that piston body 1 is big groove up and down is provided with leather cup shoulder 5, the uniform individual fastening leather cup tapped hole 7 of 6-8 that is provided with of the table top centerline upper and lower surface of leather cup shoulder 5, piston body 1 transverse section center line is provided with ring groove 6, leather cup 3 section configurations are that half bowl-type diameter of bore equals leather cup shoulder 5 inboard circular diameters on the piston body 1, outside diameter equals the outside diameter of leather cup shoulder 5 on the piston body 1, uniformly on the center line of leather cup bottom surface be provided with 6-8 circular hole, trim ring 2 section configurations equally are that half bowl-type diameter of bore equals leather cup shoulder 5 inboard circular diameters on the piston body 1 with the section configuration of leather cup 3, trim ring 2 external diameters are less than the section thickness size of a leather cup of external diameter of leather cup 3, trim ring 2 is by corresponding uniform 6-8 the circular hole that be provided with leather cup of leather cup bottom surface one side, and the big light section of shape that support ring 4 shape sizes equal ring groove 6 is that its material of rectangle is designed to wear resistant nylon.Leather cup shoulder 5 upper and lower surfaces connect leather cup 3, trim ring 2 and fastening screw trip bolt 8 respectively successively.
Improve the back use condition: when grab bucket works together, support ring 4 is relative with inboard wall of cylinder block during piston motion does axial motion, if it is not steady the cylinder body operation to occur, when adding problems such as leather cup 3 wears out, the part that is damaged at first should be a support ring 4, because these member supporting ring 4 materials are designed to wear-resisting moulding nylon, therefore the even anomaly that has can not influence use, the transfer of this damaged part, as long as prepare accessory support ring 4, a kind of improvement of transfer grab bucket cylinder piston has reduced and has scraped the cylinder phenomenon, has reduced maintenance cost.
