Embodiment Construction

[0015] As shown in the figure, in this embodiment, a rotary drilling rig with an automatic counterweight device includes a traveling mechanism 1, an operating mechanism 2, a drilling bucket mechanism 3 and a cable 4, and the above four constitute the whole of the rotary drilling rig The structure also includes a counterweight mechanism 5. In order to facilitate operation, the operating mechanism 2 is provided with a console, and the front and rear ends of the console are respectively provided with a drilling bucket mechanism 3 and a counterweight mechanism 5. The drilling bucket mechanism 3 rotates for construction, and the counterweight Mechanism 5 to balance its weight, drill bucket mechanism 3 is connected with counterweight mechanism 5 through cable 4;

[0016] In this embodiment, the counterweight mechanism 5 includes a sliding platform 505 and a counterweight box 501 slidingly arranged with the sliding platform 505, and the position of the center of gravity of the counter...

Abstract

The invention provides a rotary drilling machine with an automatic counterweight device in order to solve the problem that a counterweight mechanism cannot conduct weight counterbalance in time. The rotary drilling machine comprises a travelling mechanism, a manipulating mechanism, a drilling bucket mechanism and a mooring rope and further comprises a counterweight mechanism, the drilling bucket mechanism is connected with the counterweight mechanism through the mooring rope, and the counterweight mechanism comprises a sliding table and a counterweight box slidably arranged with the sliding table and further comprises a first pulley, a second pulley and a third pulley, wherein the first pulley and the second pulley are arranged at the front end and the rear end of the sliding table correspondingly, and the third pulley is arranged over the second pulley. The mooring rope passes through the first pulley, the second pulley and the third pulley in sequence and then is connected with the counterweight box, and thus the structure that the drilling bucket mechanism downwards falls to drive the counterweight box to slide backwards along the sliding table is constituted. According to the rotary drilling machine with the automatic counterweight device, the mooring rope is directly connected with the counterweight mechanism, the effect that the torque of the front end and the rear end ofa manipulating table is balanced is achieved, and automatic weight counterbalance is achieved.

Description

technical field [0001] The invention relates to the technical field of engineering equipment, in particular to a rotary drilling rig. Background technique [0002] Rotary drilling rigs are widely used in various constructions such as high-rise buildings, bridges, and highways. Due to the complex working conditions of rotary drilling rigs, the stability of the whole machine must be ensured during the construction process. According to different strata requirements, different types of rotary drilling rigs are used. Construction methods and drilling tools, the multi-functionality of the drilling rig will require the drilling rig to use different working devices. In addition, due to the different depths of the drill bits at the front end of the rotary drilling rig, there will be a large difference in the weight of the front end of the rotary drilling rig. The difference in weight requires The weight of the rear counterweight is matched with it to maintain the stability requireme...
