The spacing and speed limiting system of the coal cutter provided by the utility model is used for solving the problem that the traction part of the coal cutter is damaged by a traditional physical limiting method of the coal cutter, implementing the spacing and speed limiting of the coal cutter when the coal cutter walks along a scraper conveyor through reasonable automatic control from the perspective of electricity, releasing the attention of an operator and improving the production efficiency and safety.
Description
Technical field
The utility model belongs to coal excavation apparatus technical field, relates to a kind of coal-winning machine control system, relates in particular to the spacing speed limiting system of a kind of coal-winning machine.
Background technology
In Mechanized, coal-winning machine is walked along drag conveyor, in two terminations of drag conveyor, the necessary careful operation coal-winning machine of operating personnel, reduce hauling speed, and note observing coal winning machine position, to prevent that the coal-winning machine drag conveyor that moves out of from causing the accident; When the most notice of operating personnel is when observing coal winning machine position, often ignored the action situation of cylinder, be prone to accidents, therefore the spacing speed limiting function of coal-winning machine is particularly important.
At present, the coal-winning machine limit method of extensive use has two kinds: the one, on the pin rail of drag conveyor two ends, fixture block is installed, by realizing the guide slip shoe of coal-winning machine is spacing; The 2nd, mounting limit baffle plate in the shovel board at drag conveyor two ends, by spacing realization of support piston shoes to coal-winning machine.
These two kinds of methods are all to adopt physics spacing, and the guide slip shoe of coal-winning machine or support piston shoes touch obstruction, then by trailer system overload protection, thereby stop traction.Although these two kinds of methods are simple in structure, be very easy to damage, must often change, very inconvenient, in addition, this rigid physical impact causes very large damage to the traction element of coal-winning machine.And two ends, there is no hauling speed restriction, still need operator to divert one's attention to operate.
Along with mine is more and more stronger to the requirement of high-yield and high-efficiency and safety in production, need coal-winning machine automatically realize near the automatic speed-limiting of termination and tip position automatically stop traction, make operating personnel without the coal winning machine position of diverting one's attention, attentively operate cylinder cutting rib.
In recent years; also have to adopt and on stopping means, increase expansion link or buffering device; in order to weaken the impact to shearer haulage part; but do not change in essence; still rely on physical restriction, overload protection to stop coal-winning machine, impact and just reduce, but still exist; and there is no the volitional check of hauling speed, could not thoroughly deal with problems.
In view of this, nowadays in the urgent need to designing the spacing speed-limiting proposal of a kind of new coal-winning machine, to overcome the above-mentioned defect of existing spacing speed-limiting proposal.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of coal-winning machine spacing speed limiting system, can solve coal-winning machine along the spacing and speed limit problem of drag conveyor walking, liberation operating personnel's concern power, improves efficiency and the safety of producing.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
The spacing speed limiting system of coal-winning machine, described system comprises: controller, sensor, input module, described controller is connecting sensor, input module respectively;
Described sensor setting, in shearer hauled-part, in order to gather travel distance and the speed of travel data of coal-winning machine, and is sent to controller;
Described input module is in order to input setting data to controller;
The setting data of the travel distance of the coal-winning machine that described controller gathers according to sensor and speed of travel data, input module input is controlled coal-winning machine walking.
As a kind of preferred version of the present utility model, described sensor comprises range sensor and velocity sensor, respectively in order to gather travel distance and the speed of travel data of coal-winning machine.
As a kind of preferred version of the present utility model, the master controller that described controller is coal-winning machine.
The beneficial effects of the utility model are: the spacing speed limiting system of coal-winning machine the utility model proposes, solved in the past and damaged shearer haulage problem partly in coal-winning machine physics limit method, the real angle from electricity, rationally by automation, control, solved the spacing and speed limit problem of coal-winning machine along drag conveyor walking, liberate operating personnel's concern power, improved efficiency and the safety of producing.
Accompanying drawing explanation
Fig. 1 is the composition schematic diagram of the spacing speed limiting system of the utility model coal-winning machine.
The specific embodiment
Below in conjunction with accompanying drawing, describe preferred embodiment of the present utility model in detail.
Embodiment mono-
Refer to Fig. 1, the utility model has disclosed the spacing speed limiting system of a kind of coal-winning machine, and described system comprises: controller 1, sensor 2, input module 3, and described controller 1 is connecting sensor 2, input module 3 respectively; Described controller 1 can be the master controller of coal-winning machine.
Described sensor 2 is arranged at shearer hauled-part, in order to gather travel distance and the speed of travel data of coal-winning machine, and is sent to controller.In the present embodiment, described sensor 2 comprises range sensor and velocity sensor, respectively in order to gather travel distance and the speed of travel data of coal-winning machine.
Described input module 3 is in order to input setting data to controller 1; As between speed limit, spacing zone.
The setting data of the travel distance of the coal-winning machine that described controller 1 gathers according to sensor 2 and speed of travel data, input module 3 inputs is controlled coal-winning machine walking.
Embodiment bis-
The difference of the present embodiment and embodiment mono-is, in the present embodiment, at shearer hauled-part sensor installation, in order to detect travel distance and the speed of travel of coal-winning machine.In scratch board conveyor, any point is set to position zero point, can by measure in coal-winning machine master controller, arrange termination, work plane left and right with respect to the position distance at zero point, also can automatically move and obtain and preserve by coal-winning machine, then in coal-winning machine master controller, arrange with respect to the deceleration buffer distance of tip position and the hauling speed of buffer strip, by the automatic processing of coal-winning machine master controller, when coal-winning machine moves to buffer strip, with the hauling speed operation arranging, when running to tip position, traction stops automatically.When work plane produces change in length, can by button, reset adjustment at any time, to meet production requirement.
In sum, the spacing speed limiting system of coal-winning machine the utility model proposes, solved in the past and damaged shearer haulage problem partly in coal-winning machine physics limit method, the real angle from electricity, rationally by automation, control, solve the spacing and speed limit problem of coal-winning machine along drag conveyor walking, liberated operating personnel's concern power, improved efficiency and the safety of producing.
