Embodiment Construction

[0017] Such as figure 1 and figure 2 As shown, a transfer case of a core drilling rig comprises a case body 1. The case body 1 includes an upper case body and a lower case body. Fixed connection. The support plate 2 that both sides of the lower casing have is installed on the front frame of the drilling rig by the first bolt 3 . The upper box body is provided with a vent plug 4, and the lower box body is provided with an oil plug 21. The side wall of the lower box above the support plate 2 is provided with a port, and the port is sealed and installed by the cover plate 8 and the second bolt 7 .

[0018] A shift fork shaft 9 is inserted into the upper part of the case, and the two ends of the shift fork shaft 9 are installed on the case through bearing sleeves 10, and one end of the shift fork shaft 9 located outside the case is connected with a handle 13 through a cylindrical pin 11. The bearing sleeve is fixed on the casing by countersunk head screws 12. A shift fork 28...

Abstract

The invention discloses a transfer case for a core drill. The transfer case comprises a case body. A shifting fork shaft is arranged inside the case body. The two ends of the shifting fork shaft are installed on the case body through bearing housings. The middle of the shifting fork shaft is sleeved with a shifting fork. The shifting fork is provided with a shifting block. A first shaft, a second shaft and an input shaft are sequentially installed inside the case body. The shifting block arranged on the shifting fork is matched with the first shaft. A first gear and a clutch internal gear are installed on the first shaft. A small arc tooth bevel gear is installed at one end of the first shaft. A duplex gear is installed on the second shaft. A second gear is installed on the input shaft. The duplex gear is meshed with the first gear and the second gear. Due to the fact that the duplex gear is meshed with the first gear and the second gear, four-level forward rotation speed and one-level reverse rotation speed are input by means of the input shaft, power is transmitted to a drilling machine gyrator or a winch through the second gear, the duplex gear, the first gear, an idle gear, an inner tooth ring and a hollow shaft gear, and the good transfer and speed changing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a core drilling machine, in particular to a transfer case for the core drilling machine. Background technique [0002] Core drilling rig is a kind of core drilling equipment, which is mainly used for the general survey and exploration of metal and non-metallic solid minerals. In addition, it can also be used for engineering geological survey, hydrogeological survey, oil and gas field survey and exploration, and water well drilling, etc. The core drilling rig transfer case is a device that distributes the power of the engine, and can output the power to the rear axle, or to the front / rear axle at the same time. The transfer case of the core drilling rig in the prior art cannot well meet the rotational speed requirements for the transfer and speed change of the gyrator and the hoist. Contents of the invention [0003] The object of the present invention is to prov...
