Abstract
The utility model relates to a displacement type big-block-removal machine of a thermal power plant coal conveying system. The displacement type big-block-removal machine is called as a big-block-removal machine due to the fact that big-block materials such as big-block coal gangues and big-block timbers in raw coal can be removed by the big-block-removal machine when the big-block-removal machine normally operates, and the displacement type big-block-removal machine can overcome the shortcoming that an existing big-block-removal machine cannot move. When chute blockage happens, the displacement type big-block-removal machine can automatically move to certain positions to automatically remove the chute blockage. A structure of the displacement type big-block-removal machine comprises a motor-driven hydraulic push rod (1), a rail-mounted big-block-removal machine table plate (2) (a roller shaft is installed on the table plate), a pulley (3) and a pulley base (4). The driving end of the motor-driven hydraulic push rod (1) is connected with the pulley base (4), the other end of the motor-driven hydraulic push rod (1) is connected with the rail-mounted big-block-removal machine table plate (2), the upper side of the rail-mounted big-block-removal machine table plate (2) is connected with a bearing support, a rail of the rail-mounted big-block-removal machine table plate (2) is contacted with the pulley (3), the pulley (3) is contacted with the pulley base (4), and a lateral face of the pulley base (4) is connected with a coal receiving scuttle and contacted with an equipment foundation platform.
Description
Affiliated technical field
The utility model relates to the novel mechanical device that removes the bulk machine of a kind of thermal power plant coal handling system, the novel mechanical device that removes the bulk machine that especially can move automatically in the coal handling system of thermal power plant.
Background technology
The at present known bulk machine that removes, its structure is made up of roll shaft, bearing block, frame, control system that many equidirectionals rotate, and frame is connected with coal conduit and welds.The Da Shi that can remove in coal handling system in the coal except that bulk reaches timber soon.Be in operation but remove the bulk machine, the chute blockage phenomenon often arranged, especially rainy day, the high humidity of coal, easier chute blockage, when finding chute blockage, the 2-3 root roll shaft that just needs to remove in the bulk machine is dismantled, after treating that ature of coal is normal, again the roll shaft of removing is loaded onto, recovered to remove the function of bulk machine.So not only waste time and energy, influence coal handling system and normally move, and then influence the Host Security operation in thermal power plant.
Summary of the invention
In order to overcome the existing irremovable shortcoming of bulk machine of removing, when finding chute blockage, need 2-3 root roll shaft is dismantled, could solve like this and remove bulk machine chute blockage problem, also to overcome the unsafe again shortcoming of operation that wastes time and energy.
The utility model provides a kind of thermal power plant coal handling system the novel bulk machine that removes, and this is novel to remove the bulk machine and can remove the bulk materials in the raw coal to wait as (coarse coal spoil, bolt) when normal operation and remove, so cry except that the bulk machine; When chute blockage appears in this machine, just automatically move to certain position, automatically terminate the chute blockage phenomenon.
Of the present utility model being configured with: electric drive hydraulic thruster (1), rail mounted remove bulk machine bench (2), pulley (3), pulley base (4) composition.Electric drive hydraulic thruster (1) can solve the novel bulk seat in the plane of removing and put mobile problem, rail mounted removes bulk machine bench (2) and can solve except that putting orientation problem when mobile in the bulk seat in the plane, pulley (3) can solve the directionality problem of displacement, and pulley (4) base is used for fixing pulley, solves and remove the stability that the bulk seat in the plane is moved.When coal is gone up in the belt feeder operation, during raw coal high humidity chute blockage, the action of automatic controlling system (automatic or manual) electric drive hydraulic thruster is arranged, make except that moving the bulk seat in the plane, eliminate chute blockage, guarantee that coal handling system normally moves.The drive end of electric drive hydraulic thruster (1) is connected with pulley base (4), top and the bearing block that rail mounted removes bulk machine bench (2) is connected, the track that rail mounted removes bulk machine bench (2) contacts with pulley (3), pulley (3) contacts with pulley base (4), and the side of pulley base (4) is connected with the coal breakage bucket, contacts with the Equipment Foundations platform.
The beneficial effects of the utility model are: the reliability that has improved whole coal handling system; the novel bulk machine that removes is according to the automatic displacement of setting program when the raw coal high humidity; assurance equipment moves under the situation of chute blockage not; or the operations staff can manually adjust the device location operation according to the ature of coal situation; do not need the maintainer shutting down its equipment roll shaft of dismounting; save time, laborsaving; avoided the belt feeder chute blockage effectively; guaranteed the normal operation of belt feeder; improve the reliability of coal handling system, thereby also improved thermal power plant main frame reliability of operation.
Description of drawings
Fig. 1 is a side view of the present utility model.
Among the figure 1, electric drive hydraulic thruster, 2, rail mounted removes the bulk machine bench, is fixed with a plurality of bearing blocks above the platen, and bearing is housed in the bearing block, bearing is connected with roller bearing, 3, pulley, 4, the pulley base.
The specific embodiment
Among the figure in 1, the drive end of electric drive hydraulic thruster (1) is connected with pulley base (4), the other end of electric drive hydraulic thruster (1) removes bulk machine bench (2) with rail mounted and is connected, top and the bearing block that rail mounted removes bulk machine bench (2) is connected, the track that rail mounted removes bulk machine bench (2) contacts with pulley (3), pulley (3) contacts with pulley base (4), and the side of pulley base (4) is connected with the coal breakage bucket, contacts with the Equipment Foundations platform.
