Abstract
本实用新型属于机械维修用具技术领域，尤其是涉及一种牙轮钻机加压链条安装拆卸辅助装置，其特征在于在链条两侧固定有两块夹板，此两块夹板通过一组螺栓连接，在链条连接销轴的端头部位设有定位旋进管，此定位旋进管内设有与之螺纹连接的方头旋进螺栓。本实用新型能够保证加压链条在更换时安全可靠，且其余不需更换的链节不会因为人工击打造成损坏，提高了链条的使用寿命和牙轮钻机的使用寿命，降低生产成本。
The utility model belongs to the technical field of mechanical maintenance tools, and in particular relates to an auxiliary device for installation and disassembly of a pressurized chain of a roller drilling rig. The end portion of the chain connecting pin is provided with a positioning screw-in pipe, and a square head screw-in bolt threaded therein is provided in the positioning screw-in tube. The utility model can ensure that the pressure chain is safe and reliable during replacement, and the remaining chain links that do not need to be replaced will not be damaged due to manual impact, thereby improving the service life of the chain and the roller cone drilling machine, and reducing production costs.
Description
Technical field
The utility model belongs to flight-line maintenance apparatus technical field, especially relates to a kind of pressurizing chain of bit hole rig installing/dismounting servicing unit.
Background technology
In the open in the production process of mine, perforation, explosion, adopt dress, transportation is the master operation that the mine produces, rotary drill at home and abroad large surface mine is widely used.The existing rotary drill in mine relies on pressurization, slew gear to provide enough large axial pressure and rotary torque to drill bit when boring, and rock is produced static pressure and impacts the dynamic pressure effect.Chain drive advanceable continuous pressure is adopted in pressurization, because chain is the critical piece of pressurization, because long-term the use is in stress, very easily damages in the chain link plate weak link, need to irregularly check replacing.The chain links adopts bearing pin riveting system to connect, and need to manually impact and could change, and come to harm easily at the operation link hand, and chain link shortens because of External Force Acting service life.
Summary of the invention
The purpose of this utility model provides a kind of safe and efficient, and can guarantee the pressurizing chain of bit hole rig installing/dismounting servicing unit of chain stable connection.
The purpose of this utility model realizes by following technical proposals:
Pressurizing chain of bit hole rig installing/dismounting servicing unit of the present utility model, it is characterized in that being fixed with two clamping plates in the chain both sides, this two clamping plates connects by one group of bolt, the position, termination that connects bearing pin at chain is provided with location precession pipe, is provided with the square toes precession bolt that is threaded with it in this location precession pipe.
Advantage of the present utility model:
The utility model can guarantee that pressurizing chain is safe and reliable when changing, and all the other chain links that need not change can not cause damage because of manually impacting, and has improved the service life of chain and the service life of rotary drill, reduces production costs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A of the utility model Fig. 1 is to view.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, a kind of pressurizing chain of bit hole rig installing/dismounting servicing unit, it is characterized in that being fixed with two clamping plates 2 in pressurizing chain 6 both sides, this two clamping plates 2 connects by one group of bolt 1, the position, termination that connects bearing pin 5 at chain is provided with location precession pipe 4, is provided with the square toes precession bolt 3 that is threaded with it in this location precession pipe 4.
At the position that pressurizing chain of bit hole rig damages, two clamping plates 2 is fixed on the pressurizing chain 6, location precession pipe 4 is aimed at the position, termination that the chain that needs dismounting and change connects bearing pin 5, by the square toes precession bolt 3 in the precession location precession pipe 4 chain is connected bearing pin 5 and eject, the chain link that damages is laid down; The chain link that more renews, by 3 precessions of square toes precession bolt the chain that is placed in advance location precession pipe 4 being connected bearing pin 5 again heads in the pressurizing chain connecting pin axis hole also fixing, new chain link is changed complete, utilize the utility model to carry out chain link plate and change operation, greatly improve rig chain maintenance efficient, prolong the service life of pressurizing chain 6.
