[0002] The traveling hoist system is mainly used for operations such as suspending and lifting drill strings and replacing downhole tools. The traveling hoist system consists of a power unit, a second-gear power box, a winch, a traveling block and a large hook. The wire rope is wound around the winch drum, bypasses the fixed pulley of the crown block and is connected to the traveling end of the traveling hoist system. When the winch rotates forward or reverse, the wire rope pulls the traveling end up and down inside the derrick. The control of this type of traveling hoist system relies heavily on personal experience and is manually operated by the driller operator for a long time.

The driller has high labor intensity and multiple drillers need to take turns to work for long-term operations. The oilfield operation team has a serious structural shortage of personnel, and the aging population has led to a significant increase in labor costs. Utility Model Content

[0018] The utility model is described in detail and completely below in conjunction with the accompanying drawings. A person of ordinary skill in the art will be able to implement the utility model based on these descriptions. Before describing the utility model in conjunction with the accompanying drawings, it should be particularly pointed out that the technical solutions and technical features provided in each part of the utility model, including the following description, can be combined with each other without conflict.

[0019] In addition, the embodiments of the present invention involved in the following description are generally only a part of the embodiments of the present invention, rather than all of the embodiments. Therefore, based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0020] The following is a further detailed description of the utility model in conjunction with the accompanying drawings and implementations, and its specific implementation process is as follows:

[0021] like Figures 1-2 As shown, the utility model provides a traveling crane system detection device without human intervention, which is installed on an engineering vehicle 1. The device is applicable to a traveling crane system composed of a variable frequency motor, a second power gear box, a winch 2, a traveling block, a big hook, a crane and a derrick, and includes:

[0022] The variable frequency electric control device 4 is arranged on the chassis of the engineering vehicle 1. The variable frequency electric control device 4 drives the motor of the winch 2 in the traveling crane system. The variable frequency electric control device 4 can automatically adjust and control the traveling crane, and the control accuracy is higher. The variable frequency electric control device 4 and the motor of the winch 2 drive the steel wire rope on the winch 2 to move, thereby driving the traveling crane to move up and down, that is, the variable frequency electric control device 4 controls the traveling crane to move between the actual height and the target height;

[0023] The integrated detection device for the overhead crane includes a pin load sensor 5 and a rotary speed encoder 6, both of which are installed on the fast rope pulley 10 of the overhead crane. The pin load sensor 5 is used to detect the hook load of the traveling block hook 7, that is, the weight of the pipe column suspended at the lower end of the traveling block hook 7. During operation, a pipe column several kilometers long will be hung under the traveling block hook 7. The rotary speed encoder 6 is used to detect the rotation speed of the fast rope pulley 10.

[0024] The driller control terminal 3 is fixed on the working platform 9, the variable frequency electric control device 4 and the overhead travelling crane integrated detection device are connected to the driller control terminal 3, the driller control terminal 3 receives the signal detected by the overhead travelling crane integrated detection device, and the variable frequency electric control device 4 receives the command issued by the driller control terminal 3.

[0025] The technical solution may also include the following technical details to better achieve the technical effect: the variable frequency electric control device 4 is arranged in the middle of the chassis of the engineering vehicle 1 .

[0026] The present technical solution may also include the following technical details to better achieve the technical effect: it also includes a machine vision detection device 8, which is installed on the working platform 9 and is used to identify the height of the traveling block hook 7. It is installed at a suitable position on the working platform 9 to meet the harsh environment of the oil field.

[0027] The present technical scheme may also include the following technical details to better achieve the technical effect: a track is provided on the working platform 9, and the driller control terminal 3 is movably installed on the track through a base. The direction in which the track is set can be close to or away from the center of the drilling wellhead. Since explosion-proof equipment needs to be installed within 1.5 meters from the center of the wellhead, a track is provided on the working platform 9, and the distance between the driller control terminal 3 and the center of the wellhead is adjusted according to the on-site conditions, so that the distance between the driller control terminal 3 and the center of the wellhead is greater than 1.5 meters, thereby avoiding explosion-proof measures and reducing overall costs.

[0028] The technical solution may also include the following technical details to better achieve the technical effect: the pin shaft load sensor 5 is installed in the pin shaft center hole of the central axis of the fast rope wheel 10; the rotary speed encoder 6 is installed on one side of the fast rope wheel 10. The integrated detection device for the overhead crane integrates the load and speed measurement on the overhead crane. Compared with the installation method of the drum encoder and the dead rope fixer in the prior art, the installation position is closer to the load end, the error is smaller, and the detection is more accurate.

[0029] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the embodiments shown and described herein.
