Abstract
The utility model discloses a front cable trough rack of a working face transportation rack, which comprises a cable trough, wherein the outer surface of the cable trough is fixedly connected with the head of a bolt, and the tail of the bolt is sleeved with a nut; the cross section of the cable groove is U-shaped; the bolt is fixedly connected at the tail end of the cable groove; the number of the bolts is 2; the specific size of the bolt is M16 multiplied by 5; the size of the bolt is matched with that of the nut; the nut is provided with 2. The utility model discloses can realize the fastening of cable duct even, it is high to hang knot intensity, the degree of reducing wear, the life of detaining is hung in the extension, prevent that dropping of cable frame from leading to the cable to fall to the ground, crowded cable that hinders for the cable frame is more firm, workman's safety has been ensured, thereby more importantly can adjust the position of bolt and nut according to actual need and change the height of cable duct, when connecting the position and producing wearing and tearing moreover, restore only need with the nut replace into new can, the waste of resource has been reduced.
Description
Technical Field
The utility model belongs to the technical field of coal mining equipment, concretely relates to cable trough frame before working face transportation frame.
Background
The traditional underground coal mining method is characterized in that a large number of workers operate equipment to mine coal underground, and with the national requirement on safe production of coal mines, resources are fully utilized, the safe production is guaranteed, and particularly, a thin coal seam is mined, wherein the structure of a cable trough becomes a key. General underground someone is supporting cable duct of working face for whole rigid structure, cable duct before traditional working face transportation frame, the use is hung to detain the examination, but hang to detain intensity not enough, with too long time will wear and tear the grow, make to hang to detain and lose the effect, the cable frame will drop and lead to the cable to fall to the ground, can move the crowded cable that hinders of frame sometimes, produce the wearing and tearing back, lead to the cable frame unstability easily, rock, drop even, threaten workman's safety, and in case wearing and tearing then can't restore, cause the waste.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a cable trough frame before working face transportation frame has solved the connection structure of the cable trough that exists among the prior art and has worn and torn easily, and is difficult to the problem of maintenance.
The utility model adopts the technical proposal that: the utility model provides a cable trough frame before working face transportation frame, includes the cable duct, the surface rigid coupling of cable duct has the head of bolt, the nut has been cup jointed to the afterbody of bolt.
The cross section of the cable groove is U-shaped.
The bolt is fixedly connected at the tail end of the cable groove.
The bolt is provided with 2.
The specific size of the bolt is M16 multiplied by 5.
The size of the bolt is matched with that of the nut.
The nut is provided with 2.
The utility model has the advantages that: use on the cable duct the utility model discloses a novel connected mode can realize the tight of cable duct and link firmly, hangs and detain intensity height, the degree of wear reduction, the life of detaining is hung in the extension, prevent dropping of cable frame and lead to the cable to fall to the ground, crowded cable that hinders, make the cable frame more firm, workman's safety has been ensured, thereby more importantly can adjust the position of bolt and nut according to actual need and change the height of cable duct, and when connecting the position and producing wearing and tearing, restore only need with the nut replace into new can, the waste of resource has been reduced.
Drawings
Fig. 1 is a schematic structural view of a front cable trough of a working face transportation rack of the present invention.
In the figure, 1 is a cable groove, 2 is a bolt, and 3 is a nut.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model provides a cable trough frame before working face transportation frame, includes cable duct 1, and the surface rigid coupling of cable duct 1 has the head of bolt 2, the afterbody of bolt 2 has cup jointed nut 3.
The cable trough 1 is U-shaped in cross section.
The bolt 2 is fixedly connected with the tail end of the cable trough.
The number of bolts 2 is 2.
The specific size of the bolt 2 is M16 × 5.
The bolt 2 and the nut 3 are matched in size.
The nut 3 is provided with 2.
The utility model discloses an application method does, with the head welding of bolt 2 at the end of cable duct to cup joint nut 3 and replace traditional circular hanging head on bolt 2, when connecting the position and producing wearing and tearing, restore only need with the nut replace new can.
Use on the cable duct the utility model discloses a novel connected mode can realize the tight of cable duct and link firmly, hangs and detain intensity height, the degree of wear reduction, the life of detaining is hung in the extension, prevent dropping of cable frame and lead to the cable to fall to the ground, crowded cable that hinders, make the cable frame more firm, workman's safety has been ensured, thereby more importantly can adjust the position of bolt and nut according to actual need and change the height of cable duct, and when connecting the position and producing wearing and tearing, restore only need with the nut replace into new can, the waste of resource has been reduced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
