Description

A kind of specific purpose tool for planing tool dismounting

Technical field

It the utility model is related to girdle coal plough production technique, specifically a kind of special tool for planing tool dismounting Tool.

Background technology

When underground coal mine girdle coal plough is shear, traction plane chain drives planer head to be moved back and forth in working face and completes coal-getter Make, planing tool persistently break coal and with coal wall friction, cause planing tool to wear, planing tool abrasion will excessively reduce shearing efficiency, increase plane Head running resistance, expanded motor load, need to often overhaul replacement abrasion planing tool.

Planing tool is installed in planing tool box in the prior art, is fixed by pin, in order to reduce the abrasion of pin, pin head is low Set in planing tool box end face, this just makes pin be difficult to take out, planing tool is difficult to replace, and reduces overhaul of the equipments efficiency, also have impact on The normal exploitation of working face.

The content of the invention

The purpose of this utility model is：There is provided it is a kind of for planing tool dismounting specific purpose tool, have it is small, light-weight, The features such as easy to carry, easy to process, easy to use, low to operator's operation level requirement, can be in girdle coal plough work Make face and quickly and easily dismantle planing tool, improve overhaul efficiency.

Technical solution is used by the utility model：A kind of specific purpose tool for planing tool dismounting, using overall processing Structure, including cross section for rectangle handle and be arranged on the left hook at its both ends and right hook；The α angles that left hook is formed with handle are 60 °~80 °；Right hook is 140 °~160 ° with the β angles that handle is formed；Open slot is equipped among left hook；Put down between left hook and handle Slip over and cross.

Further, the left hook width is 30mm~50mm, and the width of open slot is 15mm~20mm；The right hook width For 8mm~15mm.

The beneficial effects of the utility model are：

1st, a kind of specific purpose tool for planing tool dismounting of the utility model, using bipitch structure, one end is used for loosening pin Nail, one end are used for tilting and extracting pin, make use of lever principle, easy to operate, laborsaving, operate level requirement to operator It is low, planing tool can be quickly and easily dismantled in girdle Particleboard performance, improve overhaul of the equipments efficiency.

2nd, the utility model it is a kind of for planing tool dismounting specific purpose tool, have it is small, light-weight, easy to carry, The features such as easy to process.

Technical scheme is described in detail with reference to the accompanying drawings and detailed description.

Brief description of the drawings：

Wherein：1. the specific purpose tool dismantled for planing tool, 2. planing tool boxes, 3. planing tools, 4. fixing pins, 11. handles, 12. Left hook, 13. right hooks

Embodiment：

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of specific purpose tool 1 for planing tool dismounting of the utility model, is added using overall Work structure, including the handle 11 that cross section is rectangle and the left hook 12 and right hook 13 for being arranged on its both ends, wherein：Left hook 12 and hand The α angles that handle 11 is formed are 60 °~80 °；Right hook 13 is 140 °~160 ° with the β angles that handle 11 is formed；It is equipped with and opens among left hook 12 Mouth groove E；Seamlessly transitted between left hook and handle.Left 12 width B1 of hook is 30mm~50mm, the width B2 of open slot E for 15mm~ 20mm；Right 13 width B3 of hook is 8mm~15mm.

As shown in figure 4, when in use, first right hook 13 is inserted into the gap between planing tool box 2 and fixing pin 4, upwards Lift left hook 12 and prize fixing pin 4 to loosening, the gap increase between fixing pin 4 and planing tool box 2.As shown in figure 5, again will Left hook 12 is inserted into the gap between fixing pin 4 and planing tool box 2, is withstood left hook 12 upwards, is pressed downward right hook 13, utilization is laborsaving Lever principle, tilts and extracts fixing pin 4, then take out planing tool 3.
