Abstract
The utility model relates to a drilling depth indicator for submerged hole drills, comprising a drill rod depth driver and a digital display. The drill rod depth driver is a pulley block composed of three pulleys. The lifting distance of the steel cable of a drill rod is measured by the pulley block and input in the digital display via a flexible shaft. The display can display drilling depth at any time in drilling process, reading can reach to the accuracy of 0.1 m, operators can accurately master drilling depth according to technical requirements, drilling quality is raised, and work efficiency is increased.
Description
The utility model relates to drilling equipment.
At present, all kinds hidden hole drilling that surface mine generally uses does not all have the drilling depth display, brings very big inconvenience to work.At first, operating personnel can't accurately understand drilling depth, can only observe run of steel by rule of thumb and estimate hole depth, and error is very big; Before the enforcement explosion, must accurately survey hole depth, so that calculate the explosive amount of fill and determine blasting parameter.Surpass the boring that requires for the degree of depth, must banket,, then can't remedy for the not enough boring of the degree of depth to lower hole depth.Comprehensively above-mentioned, configuration drilling depth display unit on the hidden hole drilling is so that accurately the keyhole degree of depth is very necessary.
Hidden hole drilling drilling depth display unit of the present utility model, comprise drilling depth transmission device and digital display, the major technology characteristics are, above-mentioned drilling depth transmission device is by head pulley, pay pulley, follow-up pulley is formed, head pulley is installed between the top sheave and balladeur train bottom boom hoist cable lower sheave of hidden hole drilling balladeur train top boom hoist cable, and with top sheave and lower sheave coplane, wire rope contacts with the head pulley outer rim, so distance travelled (being the hidden hole drilling lifting distance) of wire rope determined the rotation number of above-mentioned head pulley, it is coaxial to pay pulley and head pulley, it is identical with the head pulley revolution to pay the pulley revolution, pay the pulley below and establish the follow-up pulley of coplane with it, the two connects with belt, and the rotation of paying pulley makes follow-up pulley produce corresponding the rotation by belt, so, the lifting distance of wire rope is reflected by the follow-up pulley revolution, this follow-up pulley wheel shaft one end is put a flexible axle interface, by flexible axle a digital display is passed in rotation, and drilling depth is shown.
The above-mentioned belt of paying between pulley and the follow-up pulley preferably uses V belt, to reduce driving error.
Above-mentioned digital display, the most handy mechanical digital display.
Hidden hole drilling drilling depth display unit of the present utility model, in boring procedure, its hole depth shows on display, and reading can be accurate to 0.1 meter, and operating personnel can grasp drilling depth by technical requirements exactly, improve drilling quality and operating efficiency.
Below in conjunction with embodiment the utility model is described below:
Fig. 1 looks schematic diagram for master of the present utility model.
Fig. 2 is a schematic side view of the present utility model.
Among Fig. 1-2, the top sheave of (1) boom hoist cable, (2) wire rope, (3) hidden hole drilling balladeur train, (4) head pulley of drilling depth measurement mechanism is with (1) and (13) coplane, the wheel shaft of (5) head pulley (4), (6) bearing of wheel shaft (5), on the fixing balladeur train, (7) pay pulley, and this pulley is coaxial with (4), (8) follow-up pulley, with (7) coplane, (9) belt, be used for connecting pair a pulley (7) and a follow-up pulley (8), (10) support, be fixed on the hidden hole drilling balladeur train (11) follow-up pulley wheel shaft, the flexible axle interface of (12) follow-up pulley, be connected with a flexible axle, this flexible axle other end docks with digital display, (13) wire rope lower sheave, (14) slide plate, can be along the translation of hidden hole drilling balladeur train, (15) drilling rod motor, (16) drilling rod gear-box, (17) drilling rod, (18) wire rope links to each other with hoist engine.
Claims (3)
1, hidden hole drilling drilling depth display unit, comprise drilling depth transmission device and digital display, it is characterized in that, above-mentioned drilling depth transmission device is by head pulley, pay pulley, follow-up pulley is formed, head pulley is installed between the top sheave and pulley bottom boom hoist cable lower sheave of hidden hole drilling balladeur train top boom hoist cable, and with top sheave and lower sheave coplane, wire rope contacts with this head pulley outer rim, and it is coaxial with head pulley to pay pulley, pays and establishes the follow-up pulley of coplane with it below the pulley, the two connects with belt, and this follow-up pulley wheel shaft one end is put a flexible axle interface.
According to the described display unit of claim 1, it is characterized in that 2, the connection belt between described pair of pulley and the follow-up pulley is a V belt.
According to claim 1 or 2 described display unit, it is characterized in that 3, described digital display is the mechanical type digital display.
