Abstract

The utility model discloses a mine resin explosive roll supporting pad. The utility model is characterized in that the utility model consists of a supporting pad (1) and a supporting tube (2), the supporting pad (1) has a big top and small bottom horn shape, the supporting tube (2) has a cylindrical tubular shape, and an internal screw thread is mounted in the supporting tube. After the application of the resin explosive roll supporting pad, the resin explosive roll is not affected by a drilling internal enviroment and is sucessfully jacked to the borehole bottom. The resin explosive roll is agitated completely and uniformly, which ensures the construction quality of an anchor cable support. Compared with a traditional anchor cable support, the utility model has the advantages of safety and reliability, flexibility and convenience, cost saving and good benefits. The utility model is especially suitable for the support of an underground coal roadway, which is mainly the application of the anchor cable supporting art.

Description

Mine resin powder stick pad

Technical field:

The utility model belongs to Mine anchorage cable supporting instrument machinery manufacturing technology field, is specifically related to a kind of mine resin powder stick pad.

Background technology:

Known to the inventor, the supporting to the colliery underworkings mainly is to adopt anchor pole or cable bolting technology at present.The cable bolting mode is: behind the roadway excavation, help perforating to top board or two under the coal mine, anchor into the steel strand of the inner 5-10m of country rock, in time roadway surrounding rock is carried out supporting.The technological process of cable bolting is at first to adopt the jumbolter perforating, with steel strand resin explosive roll is headed into the eyeground then, drives steel strand with jumbolter again and stirs powder stick, and powder stick solidifies the back mounting plate and rises and draw.At present, owing to the powder stick smooth end, powder stick easily dropped when the useful steel strand of major defect that exist in the cable bolting construction headed into boring with resin explosive roll; Run into boring not directly, inadequately smooth, be shaped when bad, resin explosive roll can be blocked halfway, causes steel strand to insert powder stick, causes powder stick to solidify in advance; Boring does not match with the diameter of steel strand, causes resin explosive roll fully not stir, and causes anchorage cable anchoring power deficiency.

Summary of the invention;

The purpose of this utility model is at above deficiency, and a kind of resin explosive roll that can make that provides heads into the eyeground smoothly, guarantees the mine resin powder stick pad of cable bolting construction quality.

The utility model is achieved in that described mine resin powder stick pad, is made up of pad (1) and trustship (2), it is characterized in that pad (1) is up big and down small horn shape, and trustship (2) is a drum, and trustship (2) is provided with internal thread.Its operating principle is after resin explosive roll is filled in boring, trustship (2) to be enclosed within on the steel strand, holds in the palm tight powder stick with pad (1), and powder stick is headed into boring slowly.Trustship this moment (2) separates with pad (1), and trustship (2) still is enclosed within the steel strand upper end, and the steel strand lower end is connected with jumbolter, and resin explosive roll is headed into the eyeground gradually.During this, even boring exists situation moulding such as fragmentation, crack, tomography bad because of passing the rock stratum, because the existence of trustship (2) is arranged, powder stick also can not blocked midway, and steel strand can not insert powder stick formation accident midway yet.After resin explosive roll arrives the boring end, can start jumbolter and stir powder stick,, tightly be enclosed within on the steel strand, so when jumbolter drove the steel strand rotation, trustship (2) also can be rotated together, and resin explosive roll is stirred fully because trustship (2) has internal thread.Because the existence of trustship (2) has solved steel strand diameter and the unmatched problem of bore diameter in the past, make resin explosive roll can obtain fully stirring.

Adopt mine resin powder stick pad of the present utility model, can make resin explosive roll do not holed in the influence of environment, head into the eyeground smoothly, resin explosive roll stirs full and uniform, guarantees the cable bolting construction quality, has safe and reliable, flexible, save cost, the advantage of high efficiency.

Description of drawings:

Accompanying drawing is a mine resin powder stick pad structure chart

Among the figure: 1. pad, 2 trustships,

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing embodiment, mine resin powder stick pad as shown in drawings, be to select a kind of plastics or other materials to make a up big and down small horn shape pad (1) and a circular cylindrical tubular by specification, and female trustship (2) is set, the method that adopts multipoint mode to be connected, the bottom of pad (1) and trustship (2) top linked together to get final product.

The utility model adapts to and general medium-sized and small enterprises production, does not need to increase any equipment.

Claims

A mine resin powder stick pad be by, pad (1) is formed with trustship (2), it is characterized in that pad (1) is up big and down small horn shape, trustship (2) is a circular cylindrical tubular, trustship (2) is provided with internal thread,
