Embodiment

Fig. 1 shows the front view of the tamping tool special switch magnetic resistance linear motor of the utility model, and the tamping tool is dedicated Switched relutance linear motor includes stator and mover, and mover includes that tamping tool fiddles with hammer, and stator is as shown in Fig. 1, including machine Shell 1, body, blower 2, cooling fin 4 and lead-out wire 3, wherein blower 2 includes being mounted on the positive blower of casing 1 and being mounted on machine The secondary blower at 1 back side of shell, cooling fin 4 include two cooling fins, are separately mounted to casing left side and right side, cooling fin 4 Structure is as shown in Fig. 2, and body is mounted in casing 1, lead-out wire 3 connect with body and pass through the string holes on casing 1 draw with Tamping tool connection.

In the present embodiment, casing 1 is dies, and the front and back of casing 1 is fixed by screws.

Wherein, blower when switched relutance linear motor being made to work by cooling fin 4 for being radiated.

Attached drawing 3 show the housing construction figure of the tamping tool special switch magnetic resistance linear motor of the utility model, such as Fig. 3 institute Showing, body includes control module, power inverter, current detection module, position detecting module and mover core,

Wherein, power inverter is separately connected control module and mover core.

Current detection module is separately connected control module and power inverter, for detecting mover core operating current, in electricity It cuts off the power in time when flowing through big and protects linear motor.

Position detecting module is separately connected control module and mover core.For detecting the transformation of gapped magnetic field.In this implementation Example gapped magnetic field it is optimal be 2mm, when gapped magnetic field be not equal to 2mm when in time to control module send information to linear motor into Row protection control.

In the embodiments of the present invention, control module can be microprocessor.Position detecting module can be position Sensor, it is preferred that position sensor is displacement sensor.Current detection module can be current sensor.

The straight line switch magnetic resistance linear motor of the present embodiment is such control tamping tool:

The switched relutance linear motor of the utility model embodiment includes at least three operating modes, three mode packets It includes:

(1) put hammer mode: tamping tool is in original state first, and tamping hammer is located at the top of coal bin at this time.And coal bin In coal it is seldom, microprocessor is walked downwards controlling original state of the tamping hammer at the top of the coal bin, completes one to the coal of bottom Secondary compacting；

(2) make mode firm by ramming: the mode of making firm by ramming includes n tamping cycle, and one of tamping cycle process is as follows: completion is put After hammer mode, microprocessor can control linear motor automatically or according to the control of terminal and complete following movement: to straight-line electric Machine is powered a period of time, and the conduction time is 250ms in the present embodiment, and linear motor drives tamping hammer from the period Inside rise to case top；80ms is stopped on case top behind tamping hammer arrival case top；Then linear motor declines tamping hammer, fall time It is set as 280ms, during the decline, linear motor can be set, electric power is not provided, make tamping tool by its own gravity belt Dynamic decline, can also be during the decline by linear motor to the tamping hammer one suitable lower reinforcing (size of the lower reinforcing Determine that fall time is longer according to the length of fall time, lower reinforcing is smaller), the coal of bottom is once tamped, completes one A tamping cycle.The time of a tamping cycle is 700ms in the present embodiment, but the above time can according to circumstances carry out Adjustment, and make firm by ramming in mode including how many a tamping cycles can be controlled by terminal decision or pre- in the microprocessor If.

(3) receive hammer mode: in the mode of making firm by ramming, with the coal constantly into coal bin, the height of briquette is gradually risen, and works as coal After cake height reaches technique requirement, microprocessor control tamping hammer is raised slowly to case top, returns to original state tamping tool.

The tamping tool of the switched relutance linear motor control of the present embodiment, due to being controlled by switched relutance linear motor System, frictional dissipation is small, shake it is small, noise is low, make firm by ramming a briquette with about when only need 6 minutes, the daily production in coke-oven plant Amount at least can achieve 150 furnaces, have high efficiency.And controlled by microprocessor, corresponding speed is fast, reliability Safety is also high.
