Description

An adjustable wrench for foot bolts

Technical Field The utility model belongs to the technical field of foot bolt wrench, and relates to an adjustable foot bolt wrench.

Background Art In recent years, with the rapid development of social economy, the society has put forward higher requirements for the reliability and stability of power grid power supply, which requires us to speed up the construction of power grids, strengthen the operation and maintenance of power grids, erect new lines, More and more steel pipe poles and angle steel towers are used in the transformation of buildings. In order to meet the safety requirements of these towers, their components are generally large. During the assembly process, the old-fashioned construction equipment in the past can hardly be used at all, which seriously affects the erection and erection efficiency of the towers. Heavy, on-site construction requires multiple wrenches of different types, which is extremely inflexible to carry and use. There are time-consuming and labor-intensive problems in the construction of fastening steel pipe pole foot bolts, and it is difficult to cope with the increasing speed of power grid construction and transformation.

SUMMARY OF THE INVENTION The purpose of this utility model is to solve the technical problems of time-consuming, labor-intensive, limited application environment and poor safety performance of the prior art, and provide a wrench with adjustable foot bolts.

In order to achieve the above object, the utility model provides an adjustable wrench for foot bolts, which includes a hexagonal wrench head and a wrench handle. 3 screw caps and 3 steel pipe supports with an angle of 60° are arranged alternately between the double-layer circular steel plates. The screw caps are respectively provided with twisted top wires, and the inner diameter of the steel pipes is the same as the wrench handle corresponding to the diameter. the

The utility model is safe, reliable, small and flexible, easy to install and disassemble, and has strong practical applicability. Since the interlayer of the hexagonal wrench head is provided with torsion-type top wires in three directions, the hexagonal wrench head is used in the construction of fastening the bottom bolts of steel pipe rods. The top wire can be rotated according to the size of the foot bolts, so that it can be firmly clamped with the foot bolts, which is easy to operate without carrying a variety of different types of wrenches. There are time-consuming and labor-intensive technical problems. the

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the accompanying drawings , the utility model is an adjustable wrench for foot bolts, which includes a hexagonal wrench head 1 and a wrench handle 4. Circular steel plates, the double-layer circular steel plates are alternately provided with three screw caps 5 and three steel pipes 2 with an angle of 60° for support, and the screw caps 5 are respectively provided with twisted top wires 3, The size of the inner diameter of the steel pipe 2 corresponds to the diameter of the wrench handle 4 .

The utility model can adjust the size of the hexagonal hole of the wrench from three directions, so as to meet the loading and unloading requirements of different foundation bolts. The hexagonal wrench head of the utility model can adjust the size of the inner hole in three directions according to the requirements. The wrench handle has three sockets, the total weight is about 2kg, and the production cost is 268 yuan, which can meet the use of bolt size changes. The handle is detachable, rotatable, and the socket is adjustable. the

The making and effect of each part of the utility model:

1. Twist-type top wire 3, using ф22 stainless steel screws to achieve high-precision and accurate adjustment of the wrench opening size, inverting the stainless steel screws, welding three national standard nuts in the double-layer steel plate frame of the hexagonal wrench head, each The angle between nuts is 120°.

2. Hexagonal wrench head 1 of the double-layer steel plate structure, select a steel plate with a thickness of 5mm, cut it into a circle with a diameter of 18cm, two, and open a regular hexagonal hole in the middle. Realize the close combination with the adjustable top screw and the plug-in wrench handle to ensure the safe and effective use of the machine tool. The double-layer steel plate structure is supported by 3 screw caps and 3 steel pipes, and is welded on both sides. the

3. Plug-in wrench handle 4. According to the diameter of the three steel pipe sockets, select a steel rod with a high degree of fit as the handle. The welded steel pipe is placed in the middle of the double-layer steel plate structure of the hexagonal wrench head. The angle between each steel pipe and the screw cap is 60°, and the angle between any two steel pipes is 120°. The wall thickness of the steel pipe is 3.0mm. the

The main technical problem that the utility model solves:

On May 16, 2013, the line transportation inspection team conducted a construction site trial of the adjustable foot bolt wrench. The foot bolt wrench takes 90 hours, and the utility model foot bolt adjustable wrench takes 40 hours. In a word, the utility model has the following characteristics:

1. Reduce time-consuming operation and improve work efficiency.

After the wrench is fastened to the bolt, fast and uninterrupted fastening operation can be realized. It is no longer necessary to adjust the position every 60 degrees of tightening, which can save 50% of the time. the

2. Reduce the number of wrench changeovers and save manpower and material resources:

It is no longer necessary to continuously replace different types of wrenches according to the size of the steel pipe pole foot bolts, which saves manpower, material and financial resources, and reduces the cumbersome process of selecting wrenches for bolts.
