Description
Technical field
This utility model belongs to machining equipment technical field, relates to highwall-drilling machine, particularly to the attachment structure of a kind of highwall-drilling machine lifting handle.
Background technology
Highwall-drilling machine is a kind of equipment that machining is conventional, it includes base, the column being arranged on base and the drill bit device that can move up and down on column, column is provided with tooth bar, drill bit device is provided with gear, rack and pinion engages, and drives pinion rotation to make drill bit device move up and down by the lifting handle of column side.Lifting handle is connected with the gear shaft rotated with gear synchronous by a connecting shaft.Existing connecting shaft is fixed by a bearing pin with gear shaft, bearing pin and gear shaft interference fit, and it is not very convenient to install, and in use, bearing pin easily loosens and drops.
Utility model content
The purpose of this utility model is the drawbacks described above that the attachment structure for existing lifting handle exists, and a kind of easy for installation and bearing pin provided is difficult to loosen the attachment structure of the highwall-drilling machine lifting handle dropped.
The purpose of this utility model can be realized by following technical proposal:
A kind of attachment structure of highwall-drilling machine lifting handle, including handle, connecting shaft and gear shaft, described connecting shaft one end is connected with handle, the other end is set on gear shaft and both are connected by a fixing device, it is characterised in that described fixing device includes split ring and connector, split ring is set in above-mentioned connecting shaft, this split ring annular exceedes semicircle, and above-mentioned connector one end is provided with locating piece, and the other end sequentially passes through split ring, connecting shaft and gear shaft.
In the attachment structure of above-mentioned a kind of highwall-drilling machine lifting handle, the opening part of described split ring is equipped with flange outwardly.
In the attachment structure of above-mentioned a kind of highwall-drilling machine lifting handle, described connector is arranged on the centre position of split ring opening.
In the attachment structure of above-mentioned a kind of highwall-drilling machine lifting handle, described connector is bearing pin.
Compared with prior art, this utility model exceedes the split ring of semicircle by arranging in connecting shaft, does not also fall out even if connector loosens, and connector can be installed with matched in clearance with gear shaft, installs and dismantle the most simple and convenient.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments.
As depicted in figs. 1 and 2, the attachment structure of a kind of highwall-drilling machine lifting handle that this utility model provides, including handle 1, connecting shaft 2 and gear shaft 3.Connecting shaft 2 one end is connected with handle 1, and the other end is set on gear shaft 3 and both are connected by a fixing device, so connecting shaft 2 rotates Tong Bu with gear shaft 3.
Handle 1 includes that proficiency arbor 4 and fixed cover are located at the taper knob 5 at Handle axis 4 two ends, Handle axis 4 is vertically located in connecting shaft 2, and can connecting shaft 2 relatively the most movable along Handle axis 4, turning handle axle 4 can rotate by drive connection axle 2, thus driven gear axle 3 rotates.
Fixing device includes split ring 6 and connector 7.Split ring 6 is set in connecting shaft 2, and this split ring 6 annular exceedes semicircle, and i.e. opening size is less than the diameter of axle of connecting shaft 2；Connector 7 is bearing pin, and connector 7 one end is provided with locating piece 8, and the other end sequentially passes through split ring 6, connecting shaft 2 and gear shaft 3, and connector 7 is arranged on the centre position of split ring 6 opening.
For convenience of dismounting, the opening part of split ring 6 is equipped with flange 9 outwardly.
Should be appreciated that, in claims of the present utility model, description, all " including ... " should be understood as open implication, and namely its implication is equal to " at least containing ... ", and should not be construed as enclosed implication, i.e. its implication should not be construed " only comprising ... ".
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or use similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
