Technical field
The present invention 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 applicable engineering.Mainly be suitable for the constructions such as sand, cohesive soil, slity soil, shot hole drill process, be used widely in multiple foundation basic construction.Cutting drill structurally generally includes body, mast, unit head, drilling rod and drill bit.Unit head is located on mast, and drilling rod is connected with unit head, and during cutting drill operation, drilling rod iterates through winding plant and slings and transfer.When lowering drill pipes, because of speed, when the position of unit head transferred to by drilling rod, often gravity is larger, causes larger impact to unit head.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 to arrange unit head damping device to reduce the impact to unit head when drilling rod is transferred.Current driving force head damping device adopts mechanical spring usually, but these mechanical springs can not the drilling rod of effective cache undershoot.
Summary of the invention
Can not the problem of the effective drilling rod of cache undershoot for existing damping device, the object of this invention is to provide and a kind ofly effectively can cushion the impact of drilling rod to unit head, structure is relatively simple and reliable, can extend the damping device for cutting drill unit head of machine service life to a certain extent.
The technical solution adopted for the present invention to solve the technical problems 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 matched with lower shaft 3 upper end, the upper end engagement sleeves of lower shaft 3 is contained in the branch sleeve 7 of axle 5 lower end, and snubber block 1 is installed in the position being positioned at lower shaft 3 top in branch sleeve 7, the lower port of branch sleeve 7 is provided with end cap 4, end cap 4 is provided with the through hole matched with lower shaft 3.
The present invention also can be provided with the flange connecting apparatus or outwardly anti-limit that match with end cap 4 in branch sleeve 7 lower end.End cap 4 also can adopt screw, screw rod or rivet interlacement with the lower port of branch sleeve 7.Also the boss matched with branch sleeve 7 lower end inner wall can be provided with on end cap 4 top.
The top that the present invention also can be positioned at branch sleeve 7 at lower shaft 3 is provided with more than 1 outwardly convex key 6, and the inwall of branch sleeve 7 is provided with the keyway matched with the convex key 6 in lower shaft 3 top; The keyway length of branch sleeve 7 is preferably greater than the length of convex key 6 and is less than branch sleeve 7 depth of inner cavity.
The present invention also can arrange the groove ring outwards extended bottom the keyway of branch sleeve 7.
The present invention also can be provided with damping washer 2 between convex key 6 bottom of lower shaft 3 and end cap 4.
The invention has the beneficial effects as follows: it is simple that it has manufacture, the features such as good damping effect.It is mainly applied to the bumper and absorbing shock between cutting drill unit head and drilling rod, can effectively reduce the impact of drilling rod vibrations on unit head, thus realize the object extending machine service life.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further details.
Embodiment 1, the present invention is by lower shaft 3, with composition such as snubber block 1 grade, the lower end of upper axle 5 is fixedly installed the branch sleeve 7 matched with lower shaft 3 upper end, the upper end engagement sleeves of lower shaft 3 is contained in the branch sleeve 7 of axle 5 lower end, and snubber block 1 is installed in the position being positioned at lower shaft 3 top in branch sleeve 7, the lower port of branch sleeve 7 is provided with end cap 4, end cap 4 is provided with the through hole matched with lower shaft 3, lower shaft 3 can be slided up and down in end cap 4 through hole, when lower shaft 3 is subject to greater impact, the snubber block 1 be sleeved in branch sleeve 7 can play good cushioning effect, thus the impact of drilling rod vibrations on unit head can be effectively reduced, thus reach the object extending machine service life.Consult Fig. 1 to 2.
Embodiment 2, branch sleeve 7 lower end of the present invention is provided with the flange connecting apparatus or outwardly anti-limit that match with end cap 4, mainly conveniently install, overhaul and maintain, branch sleeve 7 both can adopt bolt, screw, screw rod or rivet etc. to connect with the connection of end cap 4, and snap close, hinge etc. also can be adopted to connect; Should ensure and connect reliably, also will ensure easy to connect.Consult Fig. 1 to Fig. 2, all the other are with embodiment 1.
Embodiment 3, the top that the present invention also can be positioned at branch sleeve 7 at lower shaft 3 is provided with more than 1 outwardly convex key 6, preferably arranges 3-15, preferably 6-12 convex key 6; The inwall of branch sleeve 7 is provided with the keyway matched with the convex key 6 in lower shaft 3 top, thus can stablize the movement locus of lower shaft 3, makes axle 5 and lower shaft 3 in rotary course, can be consistent, can ensure the reliable of connection again.The keyway length of branch sleeve 7 more preferably greater than convex key 6 length and be less than branch sleeve 7 depth of inner cavity; thus make bottom the keyway of branch sleeve 7 and formed between convex key 6 top of lower shaft 3 certain have lash space, and certain protective effect can be played to machine better.Consult Fig. 1 to Fig. 2, all the other same above-described embodiments.
