Description
Technical field
The utility model belongs to belt conveyer technical field, particularly relates to a kind of belt conveyer damping supporting roller arrangement.
Background technology
At present, downward belt conveyor has become a kind of important transportation means in enterprise's productions such as mine mine, port and pier, washery, the maximum feature of downward belt conveyor be can make production system compacter, to concentrate and rationally, it is just towards long distance, large conveying quantity, high spud angle future development.
Present stage, in downward belt conveyor operational process, when the sliding force of material is greater than the every resistance sum of the conveyer of belt feeder, meeting drive motor accelerated service is until exceed the synchronous speed of motor, motor enters generating operation mode and runs, and exports lock torque, finally reaches new equilibrium point.But under electric power generation operating mode, if freight volume overload, the lock torque just easily causing motor to provide is not enough, so that belt feeder is maintained get out of hand in stable operating condition, runaway accident occurs.
Utility model content
The purpose of this utility model is to provide a kind of belt conveyer damping supporting roller arrangement, not enough to solve motor braking moment in belt conveyer that prior art provides, causes out of control at work, causes the problem that runaway accident occurs.
For solving the problems of the technologies described above, the technical solution of the utility model is: belt conveyer damping supporting roller arrangement, comprise frame, the both sides of described frame are provided with symmetry and the driven carrying roller be obliquely installed, be provided with between driven carrying roller described in two and horizontally disposed damping carrying roller, driven carrying roller described in described damping carrying roller and two all rotates and is installed in described frame, driven carrying roller described in described damping carrying roller and two depends on the load-transfer device that dynamic device drives;
Described damping carrying roller is provided with the first gear, and described frame is also provided with gear pump driven and second gear suitable with described first gear, described gear type pump connects a by pass valve, and described by pass valve is all connected with fuel tank with described gear type pump.
Improve as one, described first gear is arranged at the middle part of described damping carrying roller, and the tip diameter of described first gear is less than the race diameter of described damping carrying roller.
As further improvement, described by pass valve is connected with load cell.
As further improving, with the line of centers of described damping carrying roller for benchmark, the line of centers of described second gear is lower than the line of centers of described first gear.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
Because frame is provided with gear pump driven and second gear suitable with the first gear, thus in belt conveyer operational process, according to actual conditions, adjustment by pass valve carries out regulating the gear type pump of drive second gear movement and the pressure of whole hydraulic efficiency pressure system thereof, when not affecting load-transfer device normal transport, the damping carrying roller making the second gear mesh be provided with the first gear plays actv. braking damping, and then avoid freight volume overload, the lock torque causing motor to provide is not enough, cause the problem with there is runaway accident out of control at work, simultaneously, be convenient to pressure required for adjustment work and easy to adjust, thermal diffusivity is good, because the second gear is driven by gear type pump, thus it is large to brake dumping force at work, for normal work well is laid a good foundation.
Because the first gear is arranged at the middle part of damping carrying roller, thus effectively ensure that rack-mounted damping carrying roller stress balance in the braking of the second gear mesh first gear, not only ensure that normal work, and effectively prevent the two ends unbalance stress of damping carrying roller and cause wearing and tearing, and then affect the service life of damping carrying roller.
Tip diameter due to the first gear is less than the race diameter of damping carrying roller, thus effectively prevent damping carrying roller in the running, and the first gear be arranged on damping carrying roller contacts with load-transfer device, and causes the injury to load-transfer device.
Due to by pass valve being connected with load cell, thus according to requirements of one's work, be convenient in time by load cell, the hydraulic system pressure of fast speed to interconnective gear type pump and by pass valve carry out adjustment and control, and then realize the timely and quick adjusting of the second gear mesh first gear braking dumping force, make it reach satisfied normal requirements of one's work.
Because the line of centers of the second gear is lower than the line of centers of the first gear, is convenient to install and arrange gear type pump, meanwhile, effectively prevent the second gear and contact with load-transfer device in operation process, and cause the injury to load-transfer device.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 to Fig. 3 jointly shown in, this belt conveyer damping supporting roller arrangement, comprise frame 1, the both sides of this frame 1 are provided with symmetry and the driven carrying roller 2 be obliquely installed, be provided with and horizontally disposed damping carrying roller 4 between two driven carrying rollers 2, this damping carrying roller 4 and two driven carrying rollers 2 all rotate and are installed in frame 1, this damping carrying roller 4 and two driven carrying rollers 2 depend on the load-transfer device 3 that dynamic device drives.
The middle part of this damping carrying roller 4 is provided with the first gear 41, and the tip diameter of this first gear 41 is less than the race diameter of damping carrying roller 4; This frame 1 is also provided with gear type pump 6 to drive and second gear 61 suitable with the first gear 41, this gear type pump 6 connects a by pass valve 7, this by pass valve 7 is all connected with fuel tank 5 with gear type pump 6, this by pass valve 7 is connected with load cell, this load cell is preferably compression indicator 8, also can for can realize the device of pressure measuring function as those skilled in the art.
With the line of centers of damping carrying roller 4 for benchmark, the line of centers of this second gear 61 is lower than the line of centers of the first gear 41.
For the ease of understanding, the following principle of work giving the belt conveyer damping supporting roller arrangement that the utility model provides:
Drive and second gear 61 suitable with the first gear 41 by arranging gear type pump 6 in frame 1, thus in belt conveyer operational process, if load-transfer device 3 freight volume overloads, according to real work situation, adjustment by pass valve 7, carry out regulating the gear type pump 6 of drive second gear 61 motion and the pressure of whole hydraulic efficiency pressure system thereof, when not affecting load-transfer device 3 normal transport and work efficiency, the second gear 61 is made to play actv. braking damping to the damping carrying roller 4 being provided with the first gear 41, and then avoid the overload of load-transfer device 3 freight volume, the lock torque causing motor to provide is not enough, cause problem that is out of control in work transport and generation runaway accident, and, be convenient to pressure required for adjustment work and easy to adjust, thermal diffusivity is good, meanwhile, because the second gear 61 is driven by gear type pump 6, thus the braking dumping force produced at work is large, for normal work well is laid a good foundation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
