Abstract
Provided is a damping device for a cutting drilling machine power head. The damping device for the cutting drilling machine power head mainly solves the technical problem that an existing mechanical spring damping device can not buffer a high-speed down-shooting drill stem. The damping device for the cutting drilling machine power head is characterized in that a damping block (1) is installed on the top of a lower shaft (3) and is located between the lower shaft (3) and an upper shaft (5), a damping washer (2) is annularly arranged between the lower shaft (3) and the upper shaft (5), the upper end of and the lower end of the damping washer (2) are respectively in contact with the lower shaft (3) and an end cap (4), and the end cap (4) is tightly connected with the upper shaft (5) through a screw. The damping device for the cutting drilling machine power head has the advantages of being simple in manufacture, good in damping effect and the like. The damping device for the cutting drilling machine power head is mainly used for damping shocks between a cutting drilling machine power head and a slewing gear, reducing the influence of a machine vibration to a power head effectively, and thus the purpose of prolonging the service life of the machine is achieved.
Description
Technical field
The utility model relates to a kind of rig damping device, particularly a kind of damping device of cutting drill unit head.
Background technology
Cutting drill is the construction machinery of pore-forming operation in a kind of suitable engineering.Mainly be suitable for the constructions such as sand, cohesive soil, slity soil, the operation of shot hole Drilling, in multiple foundation basic construction, be used widely.Cutting drill structurally generally includes body, mast, unit head, drilling rod and drill bit.Unit head is located on the mast, and drilling rod is connected with unit head, and during the cutting drill operation, drilling rod is repeatedly sling by winding plant and transferred.When transferring drilling rod, because of speed, often gravity was larger when drilling rod was transferred to the position of unit head, and unit head is caused larger impact.Unit head is the critical component of cutting drill, and its performance quality directly affects the performance of the performance of cutting drill.Therefore be necessary when the unit head damping device is set transfers to reduce drilling rod the impact to unit head.Current driving force head damping device adopts mechanical spring usually, but these mechanical springs can not effectively cushion the drilling rod of high speed undershoot.
Summary of the invention
Can not effectively cushion the problem of the drilling rod of high speed undershoot for existing damping device, the purpose of this utility model provides a kind of drilling rod that can effectively cushion to the impact of unit head, structure is relatively simple and reliable, can prolong to a certain extent the damping device that is used for the cutting drill unit head of machine service life.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises lower shaft 3, upper axle 5 and snubber block 1, the lower end of upper axle 5 sets firmly the branch sleeve 7 that matches with lower shaft 3 upper ends, the upper end engage sleeves of lower shaft 3 is contained in the branch sleeve 7 of axle 5 lower ends, and snubber block 1 is installed in the position that is positioned at lower shaft 3 tops in branch sleeve 7, the lower port of branch sleeve 7 is provided with end cap 4, is provided with the through hole that matches with lower shaft 3 on the end cap 4.
The utility model also can be provided with in branch sleeve 7 lower ends the flange connecting apparatus that matches with end cap 4 or outwardly anti-limit.End cap 4 also can adopt with the lower port of branch sleeve 7 and comprise that screw, screw rod or rivet are connected.Also can be provided with on cover plate 4 tops the boss that matches with branch sleeve 7 lower end inwalls.
The utility model also can be provided with protruding key 6 outwardly more than 1 on the top that lower shaft 3 is positioned at branch sleeve 7, and the inwall of branch sleeve 7 is provided with the keyway that matches with the protruding key 6 in lower shaft 3 tops; The keyway length of branch sleeve 7 is preferably greater than the length of protruding key 6 and less than branch sleeve 7 depth of inner cavities.
The utility model also can arrange in the keyway bottom of branch sleeve 7 the groove ring of outside extension.
The utility model also can be provided with damping washer 2 between protruding key 6 bottoms of lower shaft 3 and end cap 4.
The beneficial effects of the utility model are: it has makes simply the characteristics such as good damping effect.It mainly is the bumper and absorbing shock that is applied between cutting drill unit head and the drilling rod, can effectively reduce the drilling rod vibrations to the impact of unit head, thus the purpose that realizes prolonging machine service life.
