High-speed hydraulic drilling rig with monomotor

Abstract

The invention discloses a high-speed hydraulic drilling rig with a monomotor. The high-speed hydraulic drilling rig comprises a vehicle body and a drilling boom assembly, wherein an engine is mounted on the vehicle body, the vehicle body is mounted on a chassis, and a left crawler travel device and a right crawler travel device are arranged on the chassis side by side; a straight movable boom assembly is arranged at the front part of the vehicle body, is connected with the drilling boom assembly, and can drive the drilling boom assembly to swing left and right, swing front and back, and rise and fall down. According to the drilling boom assembly of the high-speed hydraulic drilling rig disclosed by the invention, a drilling warehouse mechanism, drilling rod grabbing manipulators and disassembling and connecting rod devices are matched, so that a plurality of drilling rods can be effectively connected, and the total length of the drilling rods can be extended; a drilling boom assembly feeding mechanism adopts a steel rope structure, steel ropes are high in impact resistance, convenient to exchange and repair, and low in cost. A drilling frame adopts an integral structure and is made of aluminum alloys, so that the weight of the high-speed hydraulic drilling rig disclosed by the invention can be substantially reduced, the energy consumption of the complete vehicle can be effectively reduced, and the situation that the center of gravity of the complete vehicle faces forward can be avoided.

Description

technical field [0001] The invention belongs to the field of engineering machinery, in particular to a high-speed hydraulic drilling machine with a single engine. Background technique [0002] High-speed hydraulic drilling rig is a kind of widely used construction machinery. It is mainly composed of car body, drill arm assembly and straight arm assembly. The drill arm assembly is installed on the car body through the straight arm assembly, and Components such as an engine are arranged on the vehicle body. However, the structure and action of the straight arm assembly are very simple, and it can only drive the drilling frame to lift and swing back and forth at a small angle in the vertical plane. [0003] At the same time, the drill arm assembly is also an important part of the high-speed hydraulic drilling rig. The drill arm assembly mainly includes the drill frame, the feed mechanism, the power head mechanism, the drill pipe and the suction cover slide mechanism, and the d...

AI Technical Summary

Problems solved by technology

The function of the sliding plate mechanism of the vacuum cover is to absorb dust and prevent dust from flying all over the sky, but its vacuum rubber is an incomplete circle, so it cannot completely cover the dust generated during drilling, so that the dustproof effect is not good

[0004] The main defects of existing hydraulic drilling rigs are as follows: 1. Since the structure and action of the straight arm assembly are very simple, it can only drive the drilling arm assembly to lift and swing back and forth at a small angle in the vertical plane, resulting in The movement angle and range of the drill arm assembly are limited, which leads to the high-speed hydraulic drilling rig with a single engine has strict requirements on the working environment. For example, vertical drilling can only be done on flat ground. Some hydraulic drilling rigs have limited operating range and cannot adapt to working conditions well

[0005] 2. The main defects of the existing drill arm assembly are as follows: a, the drill arm assembly can only drive a drill rod, and the length of each drill rod is only more than 4 meters, so that the drilling depth of the drill arm assembly limited, and there is nothing to do when you want to drill a deep hole, which seriously affects the drilling depth and operating range of the high-speed hydraulic drilling rig

[0006] b. The feed mechanism is a chain structure, which will lead to the following two problems: ①The impact resistance of the chain is poor, which makes the chain easy to break when it is impacted; ②Because the chain is easy to break, it involves the problem of replacement. However, the replacement and maintenance of the chain is very difficult, which makes the problem of difficulty in replacement and maintenance very prominent; ③The price of the chain is expensive and the cost is high

[0007] c. Since the drilling rig is a steel structure combined weldment, although this structural form has high structural strength, it is heavy, which not only leads to high energy consumption of the whole vehicle, but also causes the center of gravity of the whole vehicle to face forward, which will affect the whole vehicle. car balance

[0008] 3. The existing car body is driven by the left and right crawler running devices, but the left and right crawler running devices cannot keep the car body level when encountering uneven road conditions
