Abstract

The utility model relates to the coal machinery, especially a mining four wheel driven belt conveyor comprising a coal discharging roller (1), a first driving roller (2), a second driving roller (4), a tension roller (6), a redirection roller (7), a tail roller (8) and a belt (9). A sprocket wheel (10) is disposed on the coal discharging roller (1) and the second driving roller (4) with the same turning direction, and the sprocket wheel (10) is also disposed on the first driving roller (2) and the redirection roller (7) with the same turning direction. The sprocket wheel (10) of the coal discharging roller (1) is connected with the sprocket wheel (10) of the second driving roller (4) by the chain I (11), and the sprocket wheel (10) of the first driving roller (2) is connected with the redirection roller (7) by the chain II (12). The two driving rollers of the belt conveyor has lighter weight and smaller size than the two wheel driven belt conveyor with the same power, and facilitates the down-hole transport and installation. The power of the second driving roller motor can be fully developed, and the load of the two driving motors can be equalized, whereby the driving friction area can be increased and the driving power can be enhanced.

Description

Belt transporter is moved with 4 wheel driven in the colliery

Technical field

The utility model relates to coal-cutting machinery, particularly a kind of belt transporter.

Background technology

Existing colliery is bigger with the weight and volume of two head rolls of two driving belt transport planes; be not easy to down-hole transportation and installation; because the load of two head rolls is inhomogeneous; the big motor of first head roll load burns easily or damages driving device; second head roll is then because the light motor of load can't fill a part performance power; power-handling capability is given a discount; adopt hydraulic coupler to protect between the high-performance belt transporter motor and speed reducer; but the fusible metal plug of the hydraulic coupler of first head roll melts easily; need often safeguard; can between two head rolls, synchronizer gear be set in order to solve two uneven problems of head roll load, but can increase the transmission noise.

Summary of the invention

The weight and volume that the purpose of this utility model provides a kind of head roll is little, be convenient to the down-hole transportation and install, the second head roll motor can fill a part performance power, power-handling capability is stronger colliery is with the moving belt transporter of 4 wheel driven.

Technical solution of the present utility model is: it comprises the existing coal unloading drum that comprises, first head roll, the first head roll actuating device, second head roll, the second head roll actuating device, belt tensioning drum, the changed course cylinder, the colliery of aircraft tail cylinder and belt is with two driving belt transport planes, turn to the identical coal unloading drum and second head roll, be separately installed with sprocket wheel on first head roll and the changed course cylinder, the sprocket wheel of the sprocket wheel of coal unloading drum and second head roll links to each other by chain one, and the sprocket wheel of first head roll links to each other by chain two with the sprocket wheel of changed course cylinder.

Technique effect of the present utility model is: what the weight and volume of two head rolls of this belt transporter can be than with two driving belt transport planes of power is littler, be convenient to down-hole transportation and installation, the second head roll motor can fill a part performance power, the load of two drive motor is more balanced, it has increased driving friction area, and power-handling capability is stronger.

The specific embodiment

Embodiment one, as Fig. 1, shown in Figure 2, it comprises the existing coal unloading drum 1 that comprises, first head roll 2, the first head roll actuating device 3, second head roll 4, the second head roll actuating device 5, belt tensioning drum 6, changed course cylinder 7, the colliery of aircraft tail cylinder 8 and belt 9 is with two driving belt transport planes, turn to the identical coal unloading drum 1 and second head roll 4, be separately installed with sprocket wheel 10 on first head roll 2 and the changed course cylinder 7, the sprocket wheel 10 of coal unloading drum 1 links to each other by chain 1 with the sprocket wheel 10 of second head roll 4, and the sprocket wheel 10 of first head roll 2 links to each other by chain 2 12 with the sprocket wheel 10 of changed course cylinder 7.

The first head roll actuating device 3 and the second head roll actuating device 5 are made of

electrical motor

31,51 and

reductor

32,52 respectively.31,51 input shafts with

reductor

32,52 of electrical motor link to each other respectively, and the output shaft of

reductor

32,52 links to each other with second head roll 4 with first head roll 2 respectively.Coal unloading drum 1 is equipped with the sprocket wheel 10 that is connected by chain with second head roll 4, first head roll 2 and an end of changed course cylinder 7.Belt 9 is sleeved on coal unloading drum 1, first head roll 2, second head roll 4, belt tensioning drum 6, changed course cylinder 7 and the aircraft tail cylinder 8 in turn, that coal unloading drum 1 and second head roll 4 turn to is identical, first head roll 2 turns to identical with changed course cylinder 7 and link to each other by chain, just can reach two and drive and become the purpose that 4 wheel driven moves.

Embodiment two, as shown in Figure 3, are that two ends, first head roll 2 of the coal unloading drum 1 and second head roll 4 and the two ends of the cylinder 7 that alters course are separately installed with the sprocket wheel 10 that is connected by chain with the difference of embodiment one.

Embodiment three, as shown in Figure 4, are to be separately installed with the

synchronizer gear

13,14 that is meshed on first head roll 2 and second head roll 4 with the difference of embodiment one, embodiment two.

Coal unloading drum 1 and changed course cylinder 7 become head roll to constitute 4 wheel driven with first head roll 2, second head roll 4 moving, have effectively increased power-handling capability, have improved the power-handling capability with power two driving belt transport planes.

It can realize under the situation of the weight and volume that reduces first head roll 2 and second head roll 4 that 4 wheel driven is moving, the weight and volume of the synchronizer gear of installing 13,14 is also less than two driving belt transport planes with power, both saved material, be convenient to again install and transportation,

synchronizer gear

13,14 also can be installed reach the purpose that reduces noise.
