Embodiment Construction

[0013] Such as Figure 2 to Figure 5 As shown, the main transmission and transmission system of the present invention is mainly used for power transmission inside the drilling rig, and the drilling rig includes a power source 1 (which may be an oil motor, but the present invention is not limited thereto), a main transmission and transmission system 2, Other transmission systems 3 and vertical shafts 4 for setting the drill. The main transmission and transmission system 2 and other transmission systems 3 jointly transmit the power of the power source 1 to the drilling tool on the vertical shaft 4 at different gear speeds.

[0014] The main transmission and speed change system 2 of the present invention includes a driving shaft 21 connected to the power source 1, a driven shaft 22 arranged parallel to the driving shaft 21, and a shaft that can slide axially along the driving shaft 21 is arranged on the driving shaft 21. Sliding gear set 211, a plurality of fixed gears 222 are a...

Abstract

The invention provides a main driving and speed-changing system of a drilling machine as well as an operating mechanism of the drilling machine. The main driving and speed-changing system comprises a driving shaft and a driven shaft which is arranged in parallel to the driving shaft, wherein the driving shaft is provided with a sliding gear set which can slide axially along the driving shaft; a plurality of fixed gears are distributed on the driven shaft in segments; and the meshing of the sliding gear set with the fixed gear is controlled automatically by the operating mechanism. The operating mechanism comprises a first cylinder and a second cylinder as well as an operating rod which is arranged between the first cylinder and the second cylinder and parallel to the driving shaft, wherein a shifting fork is fixed on the operating draft; and the shifting fork is connected with sliding gear set so as to drive the sliding gear set to slide axially. The main driving and speed-changing system is changed to be operated by hydraulic pressure, thus realizing the output of the rotation speed at different gears of the drilling tool of the drilling machine and being beneficial to automatic control.

Description

【Technical field】 [0001] The invention relates to a drilling rig, in particular to a main transmission and speed change system of the drilling rig and its operating mechanism. 【Background technique】 [0002] Drilling rig (drill) is a mechanical device that drives the drilling tool to drill underground to obtain physical geological data in geological exploration. Also known as drilling machine. The main function is to drive the drilling tool to break the rock at the bottom of the hole, and to lower or lift the drilling tool in the hole. It can be used to drill cores, ore cores, cuttings, gaseous samples, liquid samples, etc., to ascertain the conditions of underground geology and mineral resources. [0003] There are many models of drilling rigs, but usually a transmission system and a speed change mechanism are required. The transmission system is used to transmit power to the drilling tool, and the speed change mechanism can realize multiple speed outputs of the drilling ...
