Embodiment Construction
[0015] As shown in the figure, in this embodiment, a rotary drilling rig with automatic counterweight includes a traveling mechanism, an operating mechanism, a bucket mechanism and cables. The above four constitute the overall structure of the rotary drilling rig. For ease of operation, The operating mechanism is provided with a control device, which controls the lifting of the drilling bucket mechanism, and also includes a counterweight mechanism. In order to facilitate connection, the counterweight mechanism includes a rotating motor 1 and a counterweight box 4 connected to the rotating motor 1 through a wire rope. The counterweight box 4 There is a sliding table 5 below, and the weight box 4 and the sliding table 5 are slidingly set; driven by the rotating motor 1, the weight box 4 can slide along the sliding table 5, changing the center of gravity of the weight box 4, so as to achieve the effect of counterweight , in this embodiment, in order to facilitate the control, the ...

The invention provides a rotary drilling machine with an automatic weight counterbalance function in order to solve the problem that a weight counterbalance 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, the manipulating mechanism is provided with a control device, and the rotary drilling machine further comprises a weight counterbalance mechanism. The weight counterbalance mechanism comprises a rotary motor and a weight counterbalance box connected with the rotary motor through a steel wire rope, a sliding table is arranged below the weight counterbalance box, and the weight counterbalance box and the sliding table are slidably arranged. The rotary motor is electrically connected with the control device, the output end of the rotary motor is connected with a first rotary wheel and a second rotary wheel in series, and the first rotary wheel isconnected with the weight counterbalance box through a first moving mechanism. The second rotary wheel is connected with the weight counterbalance box through a second moving mechanism. The rotary motor of the weight counterbalance mechanism is electrically connected with the control device, forward and reverse rotation of the rotary motor is controlled through the control device, the position ofthe weight counterbalance box is changed, the automatic weight counterbalance effect is achieved, and the problem that the weight counterbalance mechanism of an existing rotary drilling machine cannot conduct weight counterbalance in time is solved.
Description
technical field [0001] The invention relates to the technical field of engineering equipment, in particular to a rotary drilling rig with automatic counterweight. 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 back-end counterweight is matched with it to...
