Embodiment Construction

[0035] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0036] see figure 1 with figure 2 , the double winch hydraulic lifting drilling tower provided by the present invention mainly includes main supporting feet (105), two auxiliary supporting feet (109), bracket (112), pulley assembly (C), lifting cylinder (D), auxiliary hoisting machine ( B), the main hoist (113) and the three-position two-way hydraulic control valve (A).

[0037] Wherein the main supporting foot (105), two auxiliary supporting feet (109), support (112), block assembly (C) form the main structure of the whole drilling tower.

[0038] see figure 1 , in an example of the present invention, the bracket (112) is integrally welded with the drill (108). The bottom end of the main support leg (105) is rotatably arranged on the suppo...

Abstract

The invention discloses a two-winch hydraulic lifting drill tower, which comprises a rise and fall oil cylinder, supporting feet, a pulley assembly, an adjusting screw and a three-position two-way hydraulic operating valve, wherein the rise and fall oil cylinder is used for rising and falling the drill tower; three pulleys corresponding to a master winch and a slave winch are arranged on the pulley assembly, and are used for respectively bearing driving drill rods on a chuck and lifting the drill rods; each pulley performs the own function, so that the drill speed is improved; the adjusting screw is used for fine-adjusting the verticality and the horizontality of the drill tower; and the three-position two-way hydraulic operating valve is used for controlling and operating the winches andlifting the drill tower. The drill tower can be arranged on various types of rock core drills to form a whole, so that the conventional tower crane separation mode is changed, the function of the drill is expanded, and frequent construction of a drill frame in drill engineering is avoided. Furthermore, a worker does not have to climb the drill tower up and down to rise, fall, disassemble and change the driving drill rods, so that the drill tower is easy to operate and convenient to maintain, and the work efficiency and the safety of people are improved.

Description

technical field [0001] The invention relates to a double winch hydraulic lifting drilling tower, in particular to an auxiliary equipment specially used for engineering exploration drilling rigs. Background technique [0002] Engineering geological drilling is an important part of geological exploration. In various engineering geological drilling, it is used to expose and divide strata and measure boundaries; identify and describe the nature, composition and composition of rock and soil; collect various undisturbed or disturbed samples , for indoor geotechnical tests, to obtain physical and mechanical data of rock and soil, and to provide necessary geological data and information for evaluation, planning and various engineering construction projects. [0003] Drilling using a drilling rig is inseparable from drilling. Drilling uses a drilling rig and a drilling tower. See the "Engineering Geological Drilling Regulations" DZ / T0017-91 of the Ministry of Geology and Mineral Reso...
