Abstract

The invention provides a steel ribbon shearing tool, which comprises: the steel binding tape cutting device comprises a binding clip and a rod-shaped handle integrally connected with the binding clip, wherein the binding clip is provided with a jaw for clamping and cutting the steel binding tape, the jaw is a long and narrow groove-shaped opening, and edges of the opening are provided with blades; the clamping part forming the jaw is an integral structure which can not move relatively. This steel ribbon shearing tool has simple structure, advantage that the practicality is strong, only needs to block the ribbon card when using and keeps silent, lifts the handle simultaneously, utilizes lever principle can accomplish the shearing of ribbon, reaches high-efficient laborsaving working effect. In addition, the rod-shaped handle of the shearing tool can also be used as a crowbar, a rope-binding bar and other tools.

Description

Steel ribbon shearing tool

The technical field is as follows:

the invention relates to the field of drilling tools, in particular to a shearing tool for a steel cable tie of a pipe.

Background art:

in the field of oil drilling and other construction and production and transportation, handling of pipe is often involved, and steel ties are the most commonly used materials for bundling pipe. At present, constructors mainly adopt bolt clippers or destruction pincers to carry out on-site shearing unsealing of steel ribbon package, but the shearing mode has the following defects: 1) the labor intensity is high, and the steel binding belt for binding the pipe fittings is usually thin and wide and can be cut short only by repeated shearing; 2) the safety is poor, and an angle grinder or flame cutting is needed to be adopted under the condition that the wire clippers or the breaking pliers are difficult to cut, so that a certain degree of potential safety hazard is brought; 3) the efficiency is low, a bundle of pipes needs to be bound by a plurality of binding belts, and the shearing time is long by using a conventional clamp tool.

The invention content is as follows:

in order to solve the problems, the invention provides the steel ribbon shearing tool which is simple in structure and practical, the shearing tool can rapidly and safely shear the ribbon, and the working timeliness is effectively improved while the labor intensity is obviously reduced.

The technical scheme of the invention is as follows:

a steel ribbon shearing tool comprises a binding clip and a rod-shaped handle integrally connected with the binding clip, wherein the binding clip is provided with a jaw for clamping and shearing a steel ribbon, the jaw is a long and narrow groove-shaped opening, and edges of the opening are provided with blades; the clamping part forming the jaw is an integral structure which can not move relatively.

Further, the width of the groove-shaped opening of the jaw is slightly larger than the thickness of the steel cable tie, and the depth of the groove-shaped opening of the jaw is larger than the width of the steel cable tie.

Further, the diameter of the handle is gradually reduced from the joint of the handle and the forceps head to the tail end of the handle.

The steel ribbon shearing tool provided by the invention has the advantages of simple structure and strong practicability, and when in use, the ribbon is clamped into the jaw, the handle is lifted at the same time, and the shearing of the ribbon can be completed by utilizing the lever principle, so that the working effect of high efficiency and labor saving is achieved. In addition, the design that the diameter of the rod-shaped handle of the shearing tool is gradually reduced from the connecting part with the binding clip to the tail part (namely the tail part of the handle is gradually reduced) enables the handle to have multiple purposes, can be used as a crow bar for prying an object or chiseling on an edge seam, and can also be used as a rope-binding bar for binding pipe fittings and the like.

Description of the drawings:

FIG. 1 is an elevation view of a steel tie shearing tool of the present invention.

FIG. 2 is a top view of the steel tie shearing tool of the present invention.

The specific implementation mode is as follows:

the technical solution of the present invention is described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the steel cable tie shearing tool comprises a binding clip 1 and a rod-shaped handle 2 integrally connected with the binding clip, wherein a jaw 3 for clamping and shearing the steel cable tie is arranged on the binding clip 1, the jaw 3 is a long and narrow groove-shaped opening, and edges of the opening are provided with blades; the clamping portion 4 constituting the jaw 3 is an integral structure which is not movable relatively. The integral structure design of the binding clip 1 or the clamping part 4 can ensure that the jaw 3 has higher firmness and stability, and the reduction of the shearing strength caused by slight opening or deformation during the clamping and shearing of the binding tape is avoided. The integrated connection design of the forceps head 1 and the handle 2 can ensure that the forceps head and the handle are firmly connected, and the handle 2 is more beneficial to facilitating the shearing of the forceps head 3 by applying lever force.

Further, the width of the slot-like opening of the jaw 3 (i.e. the slot width as seen from the front view in fig. 1) is slightly larger than the thickness of the steel cable tie, and the depth of the slot-like opening of the jaw 3 (i.e. the slot length as seen from the front view in fig. 1) is larger than the width of the steel cable tie. The above-mentioned width and the degree of depth design of keeping silent 3 can guarantee to keep silent 3 to the complete centre gripping of formation of steel ribbon, and the whole width scope of ribbon is covered to the centre gripping part, and the blade at 3 edges of keeping silent simultaneously and the space between the ribbon surface is littleer to more do benefit to the application of shearing force.

When the steel ribbon shearing tool is used for field shearing of the drilling tool packing ribbon, the ribbon is clamped into the jaw 3, the jaw 3 can completely clamp the ribbon in the width direction of the ribbon, then the handle 2 is lifted, and the ribbon is rapidly sheared by the weight of the bundled pipe or the strong tension force in the tensioning state formed by matching with the pipe grabbing machine.

Further, the diameter of the handle 2 is gradually reduced from the connection part of the handle 2 and the forceps head 1 to the tail end of the handle 2. The diameter of the handle 2 is gradually reduced from the front end (the joint with the binding clip 1) to the tail end, and the thinner tail end ensures that the handle 2 has other practical functions besides the binding clip 1 for shearing a binding tape, for example, the handle is used as a crowbar for prying an object or a smashing chisel for opening a side seam; binding of the drilling tool and fixing of the pipe frame, etc. are performed as the binding rod.

The above embodiments are only for illustrating the present invention, and all equivalent changes and modifications made on the basis of the technical solutions of the present invention should not be excluded from the scope of the present invention.
