Description

The mine anti-explosion coal loader

Affiliated technical field

The utility model belongs to mechanical field, is specifically related to a kind of structure of mine anti-explosion coal loader.

Background technology

At present, the entrucking of small-size coal mine underground coal all is artificial manual manipulation, labour intensity is big, shipment efficient is low, if adopt common truck, in the downhole operations running of high gas (coal gas, fire gases) gas explosion takes place easily again, the safety of threat to life property, in addition, the pernicious gas that common locomotive gives off is contaminated environment not only, and infringement human body physical and mental health.

Summary of the invention

The purpose of this utility model is: design a kind of mine anti-explosion coal loader, mechanized operation replaces artificial manual manipulation, reduces physical labor intensity, shortens loading time, increases economic efficiency, and realizes down-hole civilization safe in operation.

Technical solution of the present utility model is: this coal loader connects conveying mechanism by the four-wheel vehicle frame and the mechanism that shovels coal constitutes, front end at vehicle frame connects the mechanism that shovels coal, conveying mechanism is installed on vehicle frame top one side, described conveying mechanism includes transfer gantry, carrying roller, driving roller and load-transfer device, transfer gantry captive joint four-wheel vehicle frame is upper in the opposite side of operator seat, one group of carrying roller flexibly connects on the transfer gantry, the driving wheel that is connected on the four-wheel vehicle frame front end is connected with the unit head of coal loader, and load-transfer device is around on driving wheel and the one group of carrying roller; The described mechanism that shovels coal is by the bucket of shoveling coal, Hydraulic Pump and eject pump and form, and the Hydraulic Pump that is connected four-wheel vehicle frame front end and the other end that ejects pump are connected with the bucket of shoveling coal that making shovels coal and struggle against and be positioned at vehicle frame the place ahead.

Coal loader reaches the scope of operation, and the mechanism that shovels coal shovels the ground coal cinder in the bucket, and pump rises by ejecting, upset, and coal cinder promptly falls on the load-transfer device in the bucket, coal cinder is sent into the transport vehicle carriage that is positioned at the coal loader back side by load-transfer device again.

Among the figure: 1 four-wheel vehicle frame, 2 conveying mechanisms, 3 shovel coal that mechanism, 4 transfer gantries, 5 carrying rollers, 6 initiatively roll, 7 load-transfer devices, 8 backplates, 9 are shoveled coal bucket, 10 Hydraulic Pumps, 11 eject pump, 12 diesel engines, 13 change speed gear boxs, 14 operator seats

The specific embodiment

Shown in Figure 2 as Fig. 1, this coal loader connects conveying mechanism 2 by four-wheel vehicle frame 1 and the mechanism 3 that shovels coal constitutes, design four-wheel vehicle frame 1 wide 1.4m, divide the two halves sheet to use, right half sheet 0.6m installs conveying mechanism 2, described conveying mechanism 2 includes transfer gantry 4, carrying roller 5, initiatively roll 6, load-transfer device 7 and backplate 8, transfer gantry 4 is fixedly connected on the opposite side that is positioned at operator seat 14 on the four-wheel vehicle frame 1, one group of carrying roller 5 flexibly connects on the transfer gantry 4, the driving wheel 6 that is connected four-wheel vehicle frame 1 front end is connected with the unit head of coal loader, and load-transfer device 7 is around on driving wheel 6 and the one group of carrying roller 5; Air cooling type anti-explosion diesel engine 12 is installed below the transfer gantry 4, a left side half sheet 0.8m, the anterior change speed gear box 13 of installing, operator seat 14 is installed at the rear portion, diesel directly flows to change speed gear box by power-transfer clutch, change speed gear box possesses two-way function, and a unit head transmitting power is bought car in installments to take turns to wheel shaft and travelled, and another unit head transmitting power carries for conveying mechanism driving wheel 6 for belt; The described mechanism that shovels coal includes shovel coal bucket 9, Hydraulic Pump 10 and eject pump 11, and shovels coal bucket 9 bonded assembly Hydraulic Pumps 10 and eject pump 11 and be installed on the four-wheel vehicle frame 1, and the bucket 9 of shoveling coal is positioned at the front portion of four-wheel vehicle frame 1.

Coal loader is reached on the scope of operation, the bucket of shoveling coal can shovel the ground coal cinder in the bucket under the Hydraulic Pump effect, rise the bucket of shoveling coal that overturns by ejecting pump again, shoveling coal, coal cinder falls on the load-transfer device in the bucket, then load-transfer device driving wheel drive lower edge carrying roller motion coal cinder is sent into dock at vehicle frame after in the transport vehicle carriage of position.

The utlity model has following advantage: 1, explosion-proof, can be at the downhole operations of high gas and gas explosion can not take place; 2, environmental protection, the gas that gives off is harmless, free from environmental pollution after the water tank Explosion-resistant pale filters, and does not damage human body; 3, efficient, mechanization replaces artificial, reduces labour intensity, shortens the work flow time, increases economic efficiency; 4, move, coal loader is a kind of special car, can travel in the down-hole, moves to another driving surface from a driving surface.
