Its drilling efficiency directly determines the success rate of the rescue. In order to effectively solve the problem of low drilling efficiency caused by drill sticking, the rescue drill casing drive device is usually required to have a low-speed and high-torque drilling function; the maximum output torque is an important indicator for evaluating the performance of the rescue drill, and the rescue drill is required to have a maximum output torque of hundreds of thousands of Newton meters during design.
[0003] Since the casing drive device of the rescue drill has the characteristics of low speed, large diameter and large output torque, there is currently no special instrument and tooling suitable for testing its torque.

[0035] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific embodiments. Figure 1 The orientation is used as a reference.
[0036] The large-diameter casing torque testing tool and rescue drilling rig proposed in the embodiments of the present invention use a supporting tool and a pressure sensor vertically arranged with the supporting tool to perform torque testing on a casing driving device of a rescue drilling rig having low speed, large diameter and large torque characteristics.
[0037] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0038] like Figure 1-2 As shown, the test tooling includes: a pipe sleeve 2, a tooling base plate 3, a supporting tooling 4 and a pressure sensor 5. The pipe sleeve 2 is sleeved in the supporting tooling 4, the supporting tooling 4 is welded to the upper end of the tooling base plate 3, and the pressure sensor 5 is arranged at the welding point between the supporting tooling 4 and the tooling base plate 3.
[0039] The tooling bottom plate 3 is a steel plate with a thickness greater than or equal to 40 mm, which is laid flat on the horizontal ground and is used to park the rescue drilling rig 1 and the welding support tooling 4.
[0040] The rescue drilling rig 1 and the pipe sleeve 2 are the objects to be measured. After the rescue drilling rig 1 is parked on the tooling bottom plate 3, its legs are extended, and the tail support shoe and the pipe sleeve 2 are installed.
[0041] The supporting tool 4 comprises an upper bracket 4.1 and a lower bracket 4.2. Both the upper bracket 4.1 and the lower bracket 4.2 are frame structures formed by welding high-strength rectangular tubes. The lower bracket 4.2 is welded to the upper end of the tool base plate 3.
[0042] A semicircular first opening is provided in the middle of the lower end of the upper bracket 4.1. A semicircular second opening is provided in the middle of the upper end of the lower bracket 4.2. The second opening cooperates with the first opening to form the inner circle of the holding fixture 4. The diameter of the inner circle is consistent with the outer diameter of the pipe sleeve 2. The inner diameter of the holding fixture 4 can be processed into various sizes according to the outer diameter of the pipe sleeve 2 to enhance versatility (400mm to 800mm).
[0043] Upper flange planes are welded to the left and right sides of the lower end of the upper bracket 4.1, and lower flange planes are welded to the left and right sides of the upper end of the lower bracket 4.2. The upper flange plane and the lower flange plane are fixedly connected by bolts, and the pipe sleeve 2 is clamped in the inner circular hole of the supporting tooling 4 by applying a bolt pre-tightening force.
[0044] The range of the pressure sensor 5 is converted and matched according to the theoretical maximum output torque of the rescue drill, and the pressure sensor 5 is fixedly installed in the threaded base.
[0045] The lower end of the lower bracket 4.2 is provided with a first diagonal support leg and a second diagonal support leg, the first diagonal support leg is welded to the upper end of the tooling base plate 3, the second diagonal support leg is connected to the threaded base, and the second diagonal support leg and the pressure sensor 5 are perpendicular to each other.
[0046] In another embodiment, a straight support leg is provided at the lower end of the lower bracket 4.2.
[0047] The threaded base has a certain inclination angle. By setting the inclination angle of the threaded base, it is ensured that the lower bracket 4.2 and the pressure sensor 5 are always perpendicular, so that the pressure generated by the torque can be vertically transmitted to the pressure sensor 5, reducing the test error.
[0048] The second diagonal support leg is welded to the threaded base, and the threaded base is welded to the tooling bottom plate 3.
[0049] In addition to using bolts to apply pre-tightening force, the sleeve 2 and the clamping fixture 4 are also connected by intermittent welding at the front and rear sides of the first opening and the second opening to strengthen the connection.
[0050] The overturning moment generated by the torque is offset by the weight of the rescue drilling rig 1 itself, and no additional fixing device is required, which can reduce the cost to the greatest extent.
[0051] Drive the rescue drilling rig casing 2 to rotate clockwise, and lock the casing 2 under the action of the torque testing tooling. The torque generated by the rotation is transmitted to the pressure sensor 5 below through the clamping tooling 4. The product of the value displayed on the pressure sensor 5 and the span of the legs of the torque testing tooling 4 is the output torque value of the large-diameter casing.
