Abstract
The invention relates to a working head of mine excavating equipment. The working head comprises a head body provided with cutting teeth, an outer cylinder, a telescopic cylinder, a static end cover, a dynamic end cover, a bearing and a spindle, wherein the tail end of the head body is located in front of the outer cylinder; the telescopic cylinder is located in the head body and the outer cylinder and arranged on the outer side of the bearing in a sleeving manner; the telescopic cylinder and the outer cylinder are connected through a first connecting piece; the static end cover is located in the head body, one end of the static end cover is erected on the dynamic end cover, and the other end is contacted with the telescopic cylinder and the bearing and connected to the telescopic cylinder through a second connecting piece; a border is arranged on the circumferential edge of one end, contacted with the telescopic cylinder, of the static end cover, is contacted with the telescopic cylinder and is connected to the telescopic cylinder through the second connecting piece; the border and the static end cover are integrally formed. The working head of the mine excavating equipment has the benefits as follows: the head body is arranged in front of the outer cylinder, so that the diameter of the head body is not limited by the diameter of the outer cylinder, under the premise that the strength is guaranteed, the diameter of the head body in a cutting part can be small enough, and the rock breaking capacity of the cutting teeth is improved.
Description
Technical field
The present invention relates to the working head of a kind of mine excavating equipment.
Background technology
At present, home and abroad colliery sparetime university many employings development machine headwork, development machine mainly contains two kinds: one is common development machine, also claims fully-mechanized digging machine; Another kind is the pick anchoring integral unit that driving and bolt support complete simultaneously, also claims pick anchor combined unit, rock tunnelling bolting combined machine, and the cutterhead dismounting of these development machines is complicated, and labour intensity is large, and security risk is large.
Summary of the invention
Technical problem to be solved by this invention is to provide the working head of a kind of mine excavating equipment, solves the deficiencies in the prior art.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: the working head of a kind of mine excavating equipment, and its spy comprises the head body, urceolus, retracting cylinder, quiet end cap, moved end lid, bearing and the main shaft that are provided with pick; The end of described head body is positioned at the front of described urceolus; Described retracting cylinder is positioned at the inside of described head body and described urceolus, and is sheathed on outside described bearing; Described retracting cylinder and described urceolus against, be connected with described urceolus by the first connector; Described quiet end cap is positioned at the inside of described head body, and one end of described quiet end cap is erected on described moved end and covers, the other end and described retracting cylinder and described bearing touch, and is connected to described retracting cylinder by the second connector; The circumferential outer edge of one end that described quiet end cap contacts with described retracting cylinder is provided with edge, and described edge contacts with described retracting cylinder, and described second connector connects described edge to described retracting cylinder; Described edge and quiet end cap one-body molded.
The invention has the beneficial effects as follows: before head body is arranged in urceolus, the diameter of a body is not limited by the diameter of urceolus, can under the prerequisite of guaranteed strength, the diameter of head body in cutting units can be done enough little, improve the rock breaking capacity of pick, thus adapt to the larger tunnel of formation hardness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, it illustrates the cutting units of the development machine of the present embodiment, this cutting units comprises: be provided with the head body 1 of pick, urceolus 2, retracting cylinder 3, quiet end cap 4, moved end lid 5, bearing 6 and main shaft 7.
The end of described head body 1 is positioned at the front of described urceolus 2.Described retracting cylinder 3 is positioned at the inside of described head body 1 and described urceolus 2, and is sheathed on outside described bearing 6.Described retracting cylinder 3 and described urceolus 2 against, be connected with described urceolus 2 by the first connector.Described quiet end cap 4 is positioned at the inside of described head body 1, and one end of described quiet end cap 4 is erected on described moved end lid 5, and the other end contacts with described bearing 6 with described retracting cylinder 3, and is connected to described retracting cylinder 3 by the second connector.
The present embodiment makes the diameter of a body 1 not limit by the diameter of urceolus 2 before head body 1 is arranged in urceolus 2.
In the present embodiment, for coordinating the requirement of head body 1 size after reducing diameter and internal construction, carry out corresponding change to quiet end cap 4 to the size and shape of retracting cylinder 3, enable the structure after change ensure a body 1 remains unchanged with the cantilever of bearing 6 simultaneously.
Further: the circumferential outer edge of one end that described quiet end cap 4 contacts with described retracting cylinder 3 is provided with edge, and described edge contacts with described retracting cylinder 3, described second connector connects described edge to described retracting cylinder 3.Edge and quiet end cap 4 can be one-body molded.Further: described second connector is the second bolt.
Further: be provided with float grease seal 40 between moved end lid 5 and quiet end cap 4 sections, quiet end cap 4 is sheathed on described main shaft 7 by axle sleeve.
Further: between described urceolus 2 and described retracting cylinder 3, to be formed with cavity.
Further: at described retracting cylinder 3 with described urceolus 2 against place, described retracting cylinder 3 is provided with the first limiting section, and described urceolus 2 is provided with the second limiting section.Described first limiting section and the second limiting section are interlocked and described retracting cylinder 3 are connected with described urceolus 2.
Further: described first connector comprises draw-barring and the first bolt.The vertical described urceolus 2 of described draw-barring and described retracting cylinder 3 abutting contact face are arranged, and described first bolt connects described draw-barring and described retracting cylinder 3.
Further: with bolt, draw-barring to be bound up on retracting cylinder, play the effect of fixed outer cylinder 2 and retracting cylinder 3.Meanwhile, base bearing relative telescopic cylinder 3 is arranged forward, and by the reduced of quiet end cap and corresponding change shape, obtains minor diameter head body.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
