Abstract
The utility model relates to a guiding chain guard device of coal ploughs. The guiding chain guard device is characterized in that the device comprises a clevis joint, the two ends of the clevis joint are connected with a plough and a shield respectively, a plough chain is arranged inside the shield, the clevis joint is placed at a carriage, the carriage is connected to the plough and the shield in a fixing way. The guiding chain guard device is simple in structure, and belongs to a retractive force clevis joint type guiding device. The plough chain is placed in the shield, thereby the safety performance is improved greatly to be dismounted and overhauled conveniently, the force of friction is reduced, and the loss of power is reduced.
Description
Technical field:
The utility model relates to coal mining equipment, particularly coal plough.
Background technology:
Coal plough is a kind of shallow intercept form coal machine of outer traction, adopts the mode coal breakage of planing, and by the pears face of coal plough, coal is filled people's working face conveyor.In coal plough, guiding device plays an important role to running resistance and the stability of planer head.Traditional guiding is protected chain apparatus, and its shortcoming is that dismounting and the maintenance of device is inconvenient, and frictional force is large, and power loss is large, affects the motion of planer head.
Summary of the invention:
The applicant protects the above-mentioned shortcoming of chain apparatus for the guiding of traditional planer head, study and improve, and provides a kind of guiding of coal plough to protect chain apparatus, and it has simple in structure, and the loading and unloading maintenance is convenient, the characteristics that power loss is little.
In order to address the above problem, the utility model adopts following scheme:
A kind of guiding of coal plough is protected chain apparatus, it is characterized in that: comprise towing hook, the two ends of described towing hook connect respectively planer head and guard shield, device plane chain in described guard shield, and described towing hook is placed on planker, and described planker is fixedly connected with planer head and guard shield.
Technique effect of the present utility model is:
The utility model is simple in structure, belongs to rear haulage towing hook type guiding device, and plane chain is placed in guard shield, has greatly improved security performance, and is convenient to dismounting and maintenance, has not only reduced frictional force, has also reduced the loss of power.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
The utility model comprises towing hook 3, and the two ends of towing hook 3 connect respectively planer head 1 and guard shield 5, the interior device plane chain 4 of guard shield 5, and towing hook 3 is placed on planker 2, and the two ends of planker 2 are fixedly connected with planer head 1 and guard shield 5.
The utility model is simple in structure, belongs to rear haulage towing hook type guiding device, and plane chain is placed in guard shield, has greatly improved security performance, and is convenient to dismounting and maintenance, has not only reduced frictional force, has also reduced the loss of power.
