Abstract

The utility model discloses the rod body of a universal steel wire anchor rod, which has the advantages of steel saving, the reinforcement of anchoring force, and safety. The utility model is characterized in that one end of a flat waste steel wire anchor rod is sleeved in a section of round steel with an inner hole, and is processed by forging for the built-up welding of an end tail. Threads are arranged on the outer section of the round steel. The other end of the rod body of the anchor rod is divided into three kinds of forms. Form A is that the round steel whose upper section is provided with the inner hole is forged, and an end head is spot welded. Form B is that the end head is processed into the shape of an S. The push and block body of the round steel whose upper section is provided with the inner hole is forged at the neck. Form C is that the round steel of an inverted round platform body is forged, and the upper section of the round steel is provided with the inner hole. The end head is point welded. The utility model has the advantages of simple structure, economy, and durability.

Description

Universal steel wire line anchor club shaft

The utility model relates to a kind of mine equipment, especially a kind of mine working supporting equipment.

At present the rope bolt that uses in the mining is divided into two kinds of wire rope grouted anchor bar and the hollow cement-roll anchor poles of wire rope.The former is owing to only be applicable to that stablize country rock can not the immediate support top board cause the operation of sky top and restricted, seldom use now.The latter is owing to operating difficulties in work progress, and tensile strength is low, and construction quality is difficult to guarantee and can not promotes the use of.Its main cause is: 1, because screw rod and wire rope take forging and pressing and welding two procedures to finish, its forging and pressing segment thickness is greater than 20mm, and forging and pressing contact strength not enough (generally at 3--50KN).2, the cement-roll that is adopted is owing to forged and pressed the restriction of segment thickness, and can only use the cement-roll of special processing, its cement-roll internal diameter is 22mm, and wirerope diameter is between 11mm-13mm, cause between powder stick and the twine rope inner space bigger like this, in punching course, be difficult to compacting, cement-roll is closely contacted with wire rope, and cause the rotation of the wire rope body of rod.3, former wire rope cement-roll (hollow) anchor pole only is applicable to the end anchorage that the cement-roll of special shape is made, can not be general.

The purpose of this utility model is that a kind of universal steel wire line anchor club shaft will be provided, and it utilizes the waste steel wire rope to substitute reinforced anchor bolt, can strengthen anchored force, and is safe and reliable, and has saved great deal of steel.

The purpose of this utility model is achieved in that the end at straight waste steel wire line anchor club shaft is inserted in one section garden steel that has endoporus, and the opposite end tail carries out built-up welding after forging and pressing processing, and section processes screw thread outside the steel of garden, uses nut to fix other supporting equipment.The other end of anchor rod body is divided into three kinds of form: a, adopt hollow water power powder stick to do end anchorage, is inserted in one section garden steel that has endoporus at this end, and spot welding is carried out to the termination in forging and pressing processing back; B, the solid cement-roll of employing are done end anchorage, this end is processed into s shape, be inserted in one section garden steel push and block body that has endoporus at anchor rod body s shape neck place, it and anchor rod body forge into one, and the impact force that the hour hammer device is installed partly is driven into solid cement-roll through this push and block body transmission with the s of anchor rod body; C, adopt the plastics bright end anchorage of doing that expands, be inserted in the one section stage body of falling garden garden steel that has endoporus, spot welding is carried out in the termination after forging into one with anchor rod body at this end.

The utility model adopts the waste steel wire rope as anchor rod body, opposite end tail and termination are forged and pressed and soldering, have both saved great deal of steel, increased anchor rod strength again, have improved anchored force, in addition, also have characteristics such as easy to use, simple to operate, safe and reliable, highly versatile.Can obtain good economic benefit and social benefit after the all-round popularization.

Use hollow cement-roll to do the sectional drawing of the anchor rod body of end anchorage in Fig. 1.

Fig. 2 is to use solid cement-roll to do the sectional drawing of the anchor rod body end portion of end anchorage.

Fig. 3 is to use plastic expansion casing to do the sectional drawing of the anchor rod body end portion of end anchorage.

Below in conjunction with drawings and Examples the utility model is further specified.

The utility model can be taked following embodiment: cut-off footpath 11mm-13mm, long 1.5-1.7m waste steel wire rope is straight afterwards as anchor rod body (1), end at anchor rod body (1) is inserted in one section garden steel (2) that has endoporus, garden steel (2) forges and presses when diameter is 16mm, the built-up welding of end tail, outer section processes the screw thread (3) of diameter≤16mm, uses fixedly supporting plate of nut.The other end of anchor rod body (1) is divided into three kinds of form: a, adopt hollow cement-roll to do end anchorage, is inserted in one section garden steel (4) that has endoporus at this end, and spot welding is carried out to the termination in forging and pressing processing back; B, the solid cement-roll of employing are done end anchorage, this end is processed into S shape, be inserted in one section at anchor rod body (1) s shape neck place and have endoporus garden steel push and block bodies (5), it and anchor rod body (1) forge into one, and the impact force that the hour hammer device is installed partly is driven into solid cement-roll through the s that this push and block body transmits anchor rod body (1); C, adopt plastic expansion casing to do end anchorage, be inserted in the one section stage body of falling garden garden steel (6) that has endoporus, spot welding is carried out in the termination after forging into one with anchor rod body (1) at this end.
