Description
Предметом изобретени вл етс устройство дл испытани нневматических ударных механизмов, наиример бурильных молотков, путем змерени величины энергии их отдачи в процессе бурени исследуемой породы.The subject of the invention is a device for testing non-pneumatic percussion mechanisms, such as drill hammers, by measuring the magnitude of their recoil energy during the drilling process of the rock being studied.
Предлагаемое устройство вл етс более совершенным по сравнению с известными устройствами подобного рода, так как оно обеспечивает значительное упрощение испытаний указанных механизмов.The proposed device is more advanced than the known devices of this kind, since it provides a significant simplification of the tests of these mechanisms.
Это достигаетс благодар тому, что определение энергии отдачи производитс по размеру отпечатка па поверхности плоской металлической пластины, образующегос в резу;гьтате вдавливани в нластнну щарика во врем работы испытываемого молотка.This is achieved due to the fact that the recoil energy is determined by the size of the imprint on the surface of a flat metal plate formed during cutting, and the pressure is pressed into the ball during operation of the test hammer.
Дл этой цели в рассечку щтанги молотка введена муфта, в которую вход т концы штанг с укрепленными на одном из них плоской металлической пластиной, а на другом-шайбой из твердого сплава с выстуном в виде шарика, упирающегос в поверхность нластины.For this purpose, a clutch is inserted into the cutting of the hammer shank, which includes the ends of the rods with a flat metal plate fixed to one of them, and a hard metal alloy washer with ball-shaped abutment against the surface of the plate on the other.
На чертеже приведен эскиз предлагаемого устройства.The drawing shows a sketch of the proposed device.
В рассечке штанг 1 и 2 молотка устанавливаетс муфта 3, в котор ю вход т концы штанг. На одном из этих концов укреплена плоска Лгеталлическа пластина 4, а на другом шайба 5 из твердого сплава с выступом 6 в виде шарика, который упираетс в поверхность пластины 4.In rastechke rods 1 and 2 of the hammer sets the coupling 3, which includes the ends of the rods. At one of these ends there is a reinforced flat metal plate 4, and on the other, a hard metal washer 5 with a ball protrusion 6 that abuts against the surface of the plate 4.
Дл подачи к буру сжатого воздуха или промывочной воды в муфте 3 предусмотрены каналы 7.Channels 7 are provided for supplying compressed air or flushing water to the drill.
Дл определени энергии отдачи производитс кратковременное пробное бурение различных образцов горных пород. После каждого опыта измер етс диаметр отпечатка на шайбе, по размерам которого суд т об энергии отдачи;In order to determine the recoil energy, a short-term trial drilling of various rock samples is carried out. After each experiment, the diameter of the imprint on the washer is measured, the size of which determines the recoil energy;

Устройство дл испытани пневматических ударных механизмов, например бурильных молотков, путем измерени величины энергии их отдачи в процессе бурени исследуемой породы, отличающеес применением введенной в рассечку и1танги молотка муфты, в которую вход т концы штанг с укрепленными на них: на одном-плоской металлической пластинкой, а на другом-шайбой из твердого сплава с выступом в виде шарика, упирающегос в поверхность пластинки, с целью определени энергии отдачи молотка по размеру отиечатка на поверхности пластинки в результате вдавливани в нее шарика во врем работы молотка.A device for testing pneumatic percussion mechanisms, for example, boring hammers, by measuring the magnitude of their recoil energy during drilling of the rock under investigation, characterized by the use of a coupling inserted into the slot of the hammer, which includes the ends of rods mounted on them: on a single flat metal plate, on the other, a hard-alloy washer with a protrusion in the form of a ball abutting against the surface of the plate, in order to determine the recoil energy of the hammer by the size of the imprint on the surface of the plate as a result of pressing a ball into it while the hammer is operating.
