Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The cable wellhead fixture belongs to an emergency tool, is large and heavy in structure, brings inconvenience to storage, transportation, use and maintenance, and wastes manpower, material resources and financial resources.

The mode that the clamping piece is compressed tightly to the screw rod is adopted to the cable that currently commonly uses tight mode, and cable fixture divide into two symmetrical, uses ten screws, nuts to screw up in order repeatedly and ensures to press from both sides tight the cable. This clamping method has several disadvantages: 1. bolt-up formula cable fixture assembling process that uses at present is loaded down with trivial details hard, needs three to four people cooperation equipment, and wherein two people lift two cable fixtures and remain stable, lift for a long time and cause muscle fatigue easily and lead to the stability that can't keep cable fixture, another one to two people construction bolt nuts. The assembling time is long, ten screws need to be screwed down in sequence to keep the fixture flat and unchangeable, and ten screws need to be screwed down repeatedly to ensure that the stress of the ten screws is uniform. 2. Bolt fastening formula cable fixture equipment that uses at present needs bolt, nut and spanner, and it is very easy from the hand landing and cause the accident of falling the thing in the pit. 3. When the cable is clamped on the end face of the drilling tool, the cable clamp can be used only in a reverse T-shaped mode, namely, the cross rod is upward on the lower vertical rod, otherwise, the cable clamp cannot be stably clamped on the end face of the drilling tool; and the cable clamp needs to be fastened into the elevator in a positive T-shaped mode to be more stable. 4. The T-shaped cross rod of the cable clamp increases the load of the tool and occupies too much storage space, and the tool is difficult to lift for a long time during assembly. 5. The cable clamp used at present is complex in use and single in function.
