Abstract
The utility model discloses an instrument is changed to coal -winning machine hydraulic pump, including two curved parts of keeping silent, every part both ends of keeping silent is connected with stationary blade and hollow pincers barre respectively, and the inside cover of pincers barre has the extension bar. The utility model discloses an instrument is changed to coal -winning machine hydraulic pump sets up stationary blade and pincers barre respectively at the part both ends of keeping silent, between two stationary blades with two pincers barres between all through the bolt fastening, adjusting bolt twists the nut that moves the variation in size, cup joints the extension bar in pincers barre inside, can be more convenient wrongly move at narrower and small space and position nut far away convenience simple to use.
Description
Technical field
This utility model belongs to machine tool technical field, is specifically related to a kind of coal-winning machine hydraulic pump and changes instrument.
Background technology
Hydraulic pump is the visual plant of coal-winning machine, usually can occur that oil temperature raises, tractive unit has abnormal noise because of oil contamination, filter blocking in use procedure; hydraulic system leakage; the problems such as servo control mechanism slow movement, therefore, hydraulic pump uses a period of time usually to need maintenance.
Owing to hydraulic pump is positioned at liquid case inboard, and outside has many fluid pressure lines to stop, is difficult to stretch into hands dismounting nut, simultaneously limited space free-hand very difficult rotating spanner during operation, and it is very inconvenient that coal-winning machine hydraulic pump is changed in maintenance.
Utility model content
The purpose of this utility model there is provided a kind of coal-winning machine hydraulic pump and changes instrument, solves the coal-winning machine hydraulic pump maintenance existed in prior art and changes inconvenient problem.
This utility model be employed technical scheme comprise that, instrument changed by a kind of coal-winning machine hydraulic pump, and including the jaw members of two arcs, each jaw members two ends are connected to the pincers barre of stator and hollow, and the inside of pincers barre is cased with extension bar.
Feature of the present utility model also resides in,
Being cased with fixed block with extension bar socket part on the outer wall of pincers barre, fixed block is provided with fixing hole, be provided with bolt in fixing hole, pincers barre and extension bar are bolted.
All with jaw members in the same plane, stator and pincers barre stretch out along jaw members two ends respectively for stator and pincers barre.
It is bolted between two stators.
It is bolted between two pincers barres.
Extension bar is cased with hands handle away from one end of jaw members, and hands is cased with a circle rubber sleeve outside.
The beneficial effects of the utility model are, instrument changed by a kind of coal-winning machine hydraulic pump of the present utility model, stator and pincers barre it is respectively provided with at jaw members two ends, fix each through bolt between two stators and between two pincers barres, adjusting bolt turns the nut varied in size, socket extension bar inside pincers barre, it is possible to turn more easily to be in and compare small space and distant nut.

Fig. 1 is the axonometric chart that instrument changed by a kind of coal-winning machine hydraulic pump of this utility model;
Fig. 2 is the front view that instrument changed by a kind of coal-winning machine hydraulic pump of this utility model.
In figure, 1. jaw members, 2. bolt, 3. pincers barre, 4. hands handle, 5. rubber sleeve, 6. fixed block, 7. extension bar, 8. stator, 9. fixing hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Instrument changed by a kind of coal-winning machine hydraulic pump of the present utility model, and as shown in Figures 1 and 2, including the jaw members 1 of two arcs, each jaw members 1 two ends are connected to the pincers barre 3 of stator 8 and hollow to structure, and the inside of pincers barre 3 is cased with extension bar 7.
The outer wall of pincers barre 3 is cased with fixed block 6 with extension bar 7 socket part, fixed block 6 is provided with fixing hole 9, fixing hole 9 is provided with bolt 2, pincers barre 3 and extension bar 7 and is fixed by bolt 2.
All with jaw members 1 in the same plane, stator 8 and pincers barre 3 stretch out along jaw members 1 two ends respectively for stator 8 and pincers barre 3.
Connected by bolt 2 between two stators 8.
Connected by bolt 2 between two pincers barres 3.
Extension bar 7 is cased with hands 4 away from one end of jaw members 1, and hands is cased with a circle rubber sleeve 54 outsides.
The use procedure of instrument changed by a kind of coal-winning machine hydraulic pump of the present utility model: during use, size according to the required nut turned, tighten the bolt 2 on stator 8, jaw members 1 is enclosed within 4 on the nut needing to turn by hand-held hands, tighten the bolt 2 on pincers barre 3, make nut stuck in two jaw members 1, rotate hands and turn nut, dismounting or installation nut 4.
When turning the nut being in position farther out, back-out the bolt 2 in fixing hole 9, extension bar 7 is pulled out pincers barre 3, tights a bolt 2, the size according to the required nut turned, tighten the bolt 2 on stator 8, jaw members 1 is enclosed within the nut needing to turn by hand-held hands 4, tightens the bolt 2 on pincers barre 3, makes nut stuck in two jaw members 1, rotate hands and turn nut, dismounting or installation nut 4.
Instrument changed by a kind of coal-winning machine hydraulic pump of the present utility model, stator and pincers barre it is respectively provided with at jaw members two ends, fix each through bolt between two stators and between two pincers barres, adjusting bolt turns the nut varied in size, socket extension bar inside pincers barre, it is possible to turn more easily to be in and compare small space and position nut farther out.
