Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline connection, and in particular relates to a hydraulic pipe joint pressing device. Background Art

[0002] With the rapid development of the oil industry, the connection between oil field pipelines has become the key problem that all manufacturers must solve first. If the pipeline is not connected well, leakage may occur at the joint at any time. In current technology, the metal joints of the pipe are usually crimped by a crimping device, but the existing crimping devices have different degrees of low crimping accuracy, complex operation, and inconvenient mold replacement, which can easily cause the pipe joint to fall off, thereby affecting the service life of the pipeline and increasing the cost of use. When the joint core is placed more biased or tilted, resulting in a large deviation from the relative position of the outer jacket, and it is still crimped, the outer jacket will not be crimped into the groove. After the outer jacket and the joint core are misaligned, it will not only affect the later use, but also be very risky. Utility Model Content

[0003] The purpose of the utility model is to provide a hydraulic pipe joint crimping device to address the deficiencies of the prior art. The specific scheme is as follows:

[0011] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0012] Example

[0013] like Figure 1 As shown, the utility model provides a hydraulic pipe joint crimping device, including a body 1, wherein a first placement hole 2 for placing a joint core 13 is provided in the body 1, and a second placement hole 3 for placing a sleeve 14 is provided on the body 1 corresponding to the upper side of the first placement hole 2, and the first placement hole 2 and the second placement hole 3 are coaxial; a rangefinder 4 capable of simultaneously measuring multiple directions of the same horizontal plane is provided at the bottom center of the first placement hole 2; a plurality of hydraulic cylinders 7 are evenly distributed around the body 1 corresponding to the second placement hole 3, and the telescopic end of the hydraulic cylinder 7 extends into the second placement hole 3 and is provided with a crimping block 8, and the hydraulic cylinder 7 is connected to an oil distribution cylinder 11 of an oil pump 10 arranged outside the body 1 through an oil pipe 9;

[0014] The distance meter 4 and the oil pump 10 are both electrically connected to a controller 12 disposed on the top of the machine body 1 .

[0015] To facilitate adjustment of the position of the joint core 13 , a plurality of cylinders 5 are provided in the body 1 around the first placement hole 2 , and the telescopic end of the cylinder 5 extends into the first placement hole 2 . The telescopic end of the cylinder 5 is provided with a clamp 6 for clamping the joint core 13 .

[0016] Taking into account that different specifications of connectors may require different specifications of the clamping block 8, in order to facilitate replacement of the clamping block 8, the clamping block 8 is detachably connected to the telescopic end of the hydraulic cylinder 7, such as by screwing.

[0017] The specific working principle of the utility model is as follows: first, the joint core 13 is placed in the first placement hole 2, and the controller 12 is started. The controller 12 first controls the telescopic end of the cylinder 5 to extend to clamp the joint core 13, and then measures the distance from at least three points on the same circular track of the inner wall of the joint core 13 through the rangefinder 4 and transmits the data to the controller 12. The controller 12 analyzes whether the set error range is exceeded according to these data. If it does not exceed the error range, the controller 12 starts the oil pump 10, the telescopic end of the hydraulic cylinder 7 extends, and the buckling block 8 squeezes the outer sleeve 14 to connect the outer sleeve 14 with the joint core 13.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
