Abstract

The utility model provides an improved anchoring rod, which is characterized in that a rod body is composed of a lengthened rod (5) and a screw thread rod (1) with a connecting piece (4); the lengthened rod (5) is fixed to the connecting piece (4). When used for the supporting and protecting work of the anchoring rod of underground engineering, the utility model can effectively reduce the cost of construction and relieve the economic burden of users. Additionally, particularly when used for the supporting and protecting work of coal roads, the utility model also has the advantages of relieving the workload of coal cutting and protecting the cutting disk of synthetically cutting machine set.

Description

Improved anchor pole

The utility model provides a kind of improved anchor pole, and under the possession bolt support technology field of engineering.

Employed anchor pole all was to adopt all-metal material to make when China carried out the bolt support construction in underground constructions such as mine, chamber, tunnel at present, and like this, the cost height of bolt support operation brings very big burden for the user economically; In addition, particularly when this anchor metal uses in the coal roadway support operation, then need to spend great amount of manpower, in time the anchor pole in stope and the coal road is in time removed, in order to avoid the comprehensive unit of adopting is run into anchor pole and is caused comprehensive damage of adopting the unit bottom jib when the cutting coal seam, like this, the workload of coal mining activity obviously strengthens first, second also easily causes and combines the damage of adopting the unit bottom jib.

The purpose of this utility model is to provide a kind of improved anchor pole; when using in the bolt support operation of this anchor pole in underground construction; can effectively reduce construction cost; alleviate user's financial burden; in addition particularly when it is used in the coal roadway support operation, also have alleviate the coal work amount, the advantage of adopting the unit bottom jib is combined in protection.

The purpose of this utility model is achieved through the following technical solutions:

The improved anchor pole that the utility model provides, comprise the body of rod, backing plate (3), nut (2), backing plate (3) is sleeved on and has an externally threaded end on the body of rod, having an externally threaded end on nut (2) and the body of rod spins mutually, it is characterized in that: the body of rod is made up of extension bar (5) and the threaded rod (1) that has connector (4), extension bar (5) is fixed on the connector (4), and extension bar (5) adopt be with bamboo and plastics be material make mould the bamboo bar.

As seen from the above technical solution, the utility model comprises the body of rod, backing plate (3), nut (2), the body of rod then is made up of extension bar (5) and the threaded rod (1) that has connector (4), extension bar (5) is fixed on the connector (4), what account for its most extension bar (5) employing in addition in the utility model is that material is made with bamboo and plastics, low price and axial strength are high moulds the bamboo bar, and account for the utility model seldom a part backing plate (3), nut (2) and have the threaded rod (1) of connector (4) though be to adopt metal material to make, but their required firm material use quantities seldom, therefore making steel using amount of the present utility model significantly descends, its cost only is half of steel anchor pole, use of the present utility model like this, can effectively reduce construction cost, alleviate user's financial burden.

In addition; when the utility model is used in the coal roadway support operation; the extension bar (5) that the bamboo bar is moulded in employing will be anchored in the coal seam; like this; combine and adopt unit when the cutting coal seam; just need not to spend a large amount of power of going into goes the anchor pole in stope and the coal road is withdrawn in advance; directly carrying out cutting operation gets final product; combine and adopt the bottom jib of unit as running into the extension bar (5) in the utility model; not only can be at an easy rate its cut-out, and can not stay any damage on the bottom jib, therefore; when the utility model is used in the coal roadway support operation, also has the coal work of alleviating amount; the advantage of adopting the unit bottom jib is combined in protection.

Accompanying drawing:

Fig. 1 is the front view of the utility model most preferred embodiment;

Fig. 2 is the vertical view of Fig. 1.

Wherein: 1 threaded rod, 2 nuts, 3 backing plates, 4 connectors, 5 extension bars, 6 rivets, 7 draw-in grooves, 8 dovetail grooves.

The utility model is described in further detail below in conjunction with most preferred embodiment of the present utility model:

Referring to accompanying drawing, the utility model comprises the body of rod, backing plate (3), nut (2), the body of rod is made up of extension bar (5) and the threaded rod (1) that has connector (4), wherein: threaded rod (1) is provided with external screw thread, what extension bar (5) adopted is that material is made with bamboo and plastics, cross sectional shape is the rectangular bamboo bar of moulding, corrosion-resistant and the tensile strength of this bar can reach 50KN, connector (4) then is made up of end plate and two parallel side plates, and form the draw-in groove (7) of a plug-in mounting extension bar (5) between end plate and biside plate, it is interior and by the rivet of being located between connector (4) biside plate (6) that itself and connector (4) is affixed that one end of extension bar (5) is inserted into draw-in groove (7), the other end of extension bar (5) also is provided with dovetail groove (8), so that will be located at that rivet clasp agent cartridge bag in the anchor hole punctures and to rivet clasp agent stir, connector (4) is by its end plate and the welding of threaded rod (1) one end, backing plate (3) is sleeved on the end that threaded rod (1) is gone up close connector (4), and nut (2) spinning is on threaded rod (1).

The utility model can extensively be used in the bolt support operation process of underground constructions such as mine working, chamber, railway, highway, water conservancy, electric power, tunnel, is at present still at the desirable regeneration product of the steel anchor pole that uses.
