Description

A drilling rig mechanism that can prevent misoperation

technical field

The utility model relates to the field of drilling rig mechanisms, in particular to a drilling rig mechanism capable of preventing misoperation.

Background technique

The main working mechanism of the environmental protection drilling rig is located at the front end, and the working content is realized by the up and down movement of the telescopic oil cylinder of the working mechanism. Before working on the drilling rig, carefully check the equipment status and working conditions, especially the hoisting boom should be raised. If it is not raised, the top of the cylinder will collide with the bottom of the boom when the cylinder of the working mechanism is stretched, resulting in serious damage to the valve core on the top of the cylinder, which is also very destructive to the cylinder. When the valve core is damaged, the equipment can only stop working, resulting in huge losses and costs. Therefore, in order to prevent misoperation due to mistakes, an emergency stop switch is now added to the top of the oil cylinder, which can effectively avoid equipment damage.

A hoisting telescopic oil cylinder is connected therebetween, and a boom is fixed at the top of the boom. The boom is provided with a pulley, and the boom is arranged above the drilling rig telescopic oil cylinder. There is a limiter between the drilling rig telescopic oil cylinder and the boom. protective parts.

Further, the limit protection component includes an emergency stop switch.

Further, the emergency stop switch is fixed on the upper side of the telescopic oil cylinder of the drilling rig mechanism.

Further, one side of the power head bracket is hinged with the sliding frame, and the other side of the power head bracket is hinged with the sliding frame, and a drilling rig yaw oil cylinder is hinged.

Further, the power head includes an impact power head and a screw power head.

Beneficial effects: the structure of the utility model is simple and reasonable, safe and reliable, and can effectively prevent the occurrence of misoperation events, reduce equipment damage, prolong the service life of the valve core and the oil cylinder, will not cause artificial damage, reduce maintenance costs, and avoid human errors The resulting equipment downtime, maintenance, transportation and other losses indirectly improve the use efficiency of the equipment and reduce a lot of economic losses.

Detailed ways

Below in conjunction with the accompanying drawings and specific embodiments, the present utility model will be further clarified. The present embodiment is implemented on the premise of the technical solution of the present utility model. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the present utility model. range.

As shown in FIGS. 1 and 2 , the embodiment of the present invention provides a drilling rig mechanism that can prevent misoperation, including a drilling arm 1 , the drilling arm 1 is slidably connected with a carriage 2 , and the carriage 2 is connected with the drilling arm 1 . There is a telescopic oil cylinder 3 of the drilling rig, and the telescopic oil cylinder 3 of the drilling rig is controlled to be telescopic, so that the sliding frame 2 can be controlled to move up and down on the drilling arm. The carriage 2 is connected with a power head bracket 4, a power head is fixed on the power head bracket, a hoist 5 is arranged at the top of the drill arm 1, and a hoist arm 6 is slid vertically on the drill arm 1, and the lower end of the hoist arm 6 A hoisting telescopic oil cylinder is connected with the drill arm 1 , and the hoisting and telescopic oil cylinder is controlled to expand and contract, so that the hoisting arm 6 can be controlled to move up and down on the drill arm 1 . A boom 8 is fixed at the top of the hoisting arm 6, and a pulley 9 is arranged on the boom 8. The wire rope on the hoist 6 bypasses the pulley 9 and then extends downward, thereby assisting in completing the power first and other operations. The boom 8 is arranged above the telescopic cylinder 3 of the drilling rig. In order to prevent the telescopic cylinder 3 of the drilling rig from colliding with the boom 8 due to misoperation, a limit protection component is provided between the telescopic cylinder 3 of the drilling rig and the boom 8 .

The limit protection component in the embodiment of the present invention may be a proximity switch or a travel switch, and an emergency stop switch 10 is preferably used. The emergency stop switch 10 can be an emergency stop switch with a model of XALJ01C. The emergency stop switch 10 has self-locking characteristics. For example, when the boom 8 is not raised, when the telescopic cylinder 3 of the drilling rig extends and approaches the boom 8, it will The action of the emergency stop switch 10 is triggered, and the telescopic oil cylinder 3 of the drilling rig is prevented from being extended further through electrical interlocking, thereby playing the role of limit protection. According to the self-locking characteristics of the emergency stop switch 10, only after the operator lifts the boom 8 and rotates, unlocks and resets the emergency stop switch 10, can the telescopic cylinder 3 of the drilling rig be further controlled to extend, and the emergency stop switch 10 can be fixed on the boom The lower side of 8 is preferably fixed to the upper side of the telescopic oil cylinder 3 of the drilling rig mechanism.
