A high-speed hydraulic drilling rig with twin engines

Abstract

The invention discloses a high-speed hydraulic drill with two engines. The high-speed hydraulic drill comprises a vehicle body and a drill arm assembly, wherein two engines are installed on the vehicle body, the vehicle body is installed on a chassis, and a left crawler unit and a right crawler unit are arranged on the chassis side by side; and a direct-acting arm assembly is arranged at the front part of the vehicle body, is connected with the drill arm assembly, and can drive the drill arm assembly to swing left and right, swing back and forth or move up and down. According to the drill arm assembly, a plurality of drill rods can be effectively connected through coordination of a drill pipe storage mechanism, a drill rod gripping manipulator and a disconnection rod device, thereby prolonging the total length of the drill rod; and a drill arm assembly feeding mechanism adopts a wire rope structure, and the wire rope is strong in impact resistance, convenient to replace and maintain and low in cost. A drill stand adopts an integral structure and is made of aluminum alloy, so that the weight of the high-speed hydraulic drill can be greatly reduced, the energy consumption of the entire vehicle can be effectively reduced, and the center of gravity of the entire vehicle can be prevented from facing forwards.

Description

technical field [0001] The invention belongs to the field of construction machinery, in particular to a high-speed hydraulic drilling rig with dual engines. Background technique [0002] High-speed hydraulic drilling rig is a widely used construction machinery. It is mainly composed of a car body, a drill arm assembly and a straight arm assembly. The drill arm assembly is installed on the car body through the straight arm assembly. 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 drill frame to rise and fall in the vertical plane and swing back and forth at a small angle. [0003] At the same time, the drill boom assembly is also an important part of the high-speed hydraulic drilling rig. The drill boom assembly mainly includes a drill frame, a feed mechanism, a power head mechanism, a drill pipe and a dust cover sliding plate mechanism, of which the drill...

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 strict requirements on the working environment for the high-speed hydraulic drilling rig with dual engines. 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
