Problems solved by technology

Since the coring machine is driven by a gasoline engine through a reducer, the whole coring machine equipment is heavy, so it is very laborious to adjust the fixed support during use
In addition, the coring machine is located at the rear of the trailer, and the gasoline engine is directly placed on the reducer. The height is high, resulting in a high center of gravity of the core machine body, and the gasoline engine part swings greatly when working or walking, resulting in poor stability.

Embodiment Construction

[0011] Such as figure 1 and figure 2 As shown, the trailer-type hydraulic road surface coring machine is composed of a car body 16, a gasoline engine 12, a coring machine, a tool box 3, a tool box 15, a water tank 4, four fixed supports 24, wheels 22 and a hydraulic workstation. Provided with a trailer traction 18, the coring machine includes a hydraulic motor 14, a reducer 20, a coring drill 19 and a lifting device. The lifting device is composed of a rack 17 and a sliding seat 21. The rack 17 is fixed on the car body 16 and slides. The gear that rack 17 engages is arranged on seat 21, and speed reducer 20 is fixed on the slide seat 21, and the height of adjustment slide seat 21 can drive speed reducer, hydraulic motor and coring drill bit to move up and down. The hydraulic workstation includes oil tank 1, gear oil pump 2, four hydraulic cylinders 13, manual reversing valve 5, overflow valve 6, one-way valve 7, manual reversing valve 8, pressure gauge 9, manifold 10, and ai...

Abstract

The invention discloses a trailer hydraulic road core machine. The core machine comprises a core machine main body and water tank [4] arranged on a trailer car body [16] and a hydraulic power unit; and a hydrocylinder [13] is fixed above each fixed stay [24] and on the car body, and each fixed stay [24] is fixed on the piston rod [23] of the corresponding hydrocylinder. The core machine is driven by a hydraulic motor [14] and an oil pump [2] is driven by a gasoline engine [12]. The height of the fixed stays is automatically adjusted through the hydraulic mode; the entire car body has low center of gravity, uniform weight distribution, good stability and stable and reliable working performance; and full-automatic hydraulic coring can be realized, the use is convenient and labor-saving, and the operation is easy and convenient.

Description

technical field [0001] The invention relates to a trailer-type pavement coring machine mainly used for drilling and sampling asphalt pavement and concrete pavement for quality inspection. Background technique [0002] Existing trailer-type pavement coring machine is used for drilling sampling of asphalt pavement and concrete pavement, and is also used for pavement depth detection. Publication number is that the patent document of CN2500540Y discloses just such a kind of trailer-type gasoline-driven road corer, the car body is provided with gasoline engine-driven coring machine, water tank and tool box, is provided with wheels and four fixed supports under the car body , this fixed support is usually provided with a manual height adjustment device to adjust the height of the fixed support, so that the coring machine can work in a horizontal state. Since the coring machine is driven by a gasoline engine through a reducer, the entire coring machine equipment is relatively heav...
