Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention will be further described:

[0015] Such as figure 1 As shown, the automatic gluing device for the outer surface of the casing includes a glue box 1, a glue brush 2, a glue injection control device 3, a glue brush feeding mechanism, and a rotating bracket. The glue brush feeding mechanism is composed of a bidirectional motor 4 and a transmission shaft 5 , cardan shaft 6, and transmission screw 7 are connected sequentially. The rubber box 1 and the rubber brush 2 are connected through pipelines. The glue injection control device 3 is connected in series on the pipeline connecting the rubber box 1 and the rubber brush 2. The base of the rubber brush 2 Wear on the sliding polished rod 8, the transmission screw mandrel 7 of the rubber brush feeding mechanism is threadedly connected with the base of the rubber brush 2, and when the transmission screw mandrel 7 rotates, the rubber brush 2 moves in a straigh...

Abstract

The invention relates to an automatic adhesion device for an outer surface of a bushing. An adhesive box of the automatic adhesion device for the outer surface of the bushing is connected with an adhesive brush through a pipeline; an adhesive injection control device is connected in series with the pipeline for connecting the adhesive box with the adhesive brush; a pedestal of the adhesive brush is arranged on a sliding polished rod in a penetrating way; a transmission lead screw of an adhesive rush feeding mechanism is in threaded connection with the pedestal of the adhesive brush; the bushing is arranged on a rotary bracket; one end of the bushing is in threaded connection with an electric rotary disc of the rotary bracket, and the other end of the bushing is arranged together with a bearing and a bearing fixing rod of the rotary bracket; and brush hair of the adhesive brush is just in contact with the bushing. According to the automatic adhesion device, automatic adhesive brushing of an oil field bushing is realized, the entire process is automatically realized, the adhesive brush does rectilinear motion during adhesive brushing, and the brushed bushing is driven by the electric rotary disc to rotate; since the adhesive brush only does rectilinear motion, adhesive brushing on the bushing with the same force by the brush hair of the adhesive brush in an entire adhesive brushing process can be guaranteed, the automatic adhesion device is highly standard, and uniform adhesive brushing can be realized.

Description

1. Technical field: [0001] The invention relates to a device for enhancing the surface roughness of a casing designed to improve the cementing strength between the casing and the cement sheath in the oil and natural gas cementing process, and specifically relates to an automatic gluing device for the outer surface of the casing. 2. Background technology: [0002] In the technical field of oil field cementing process, for some formations, especially the layers with poor cementing effect, sticky sand casing (rubbing glue on the surface of the casing and sprinkling sand to improve the surface roughness of the casing) is often used for cementing to improve The bonding strength between the cement sheath and the casing surface improves the cementing quality of oil-water wells. At present, most of the oil field casing glue is manually operated by workers, that is, the glue is manually brushed on the surface of the casing. The sticky sand casing produced by this method has problems...
