Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of temporary angle iron anchor pile used in engineering construction, mainly applied to the field of removing anchor pile after temporary anchor pile is used, and specifically relates to an angle iron anchor pile pulling-out device. BACKGROUND

[0002] In many fields such as building construction, power engineering construction and communication engineering construction, temporary angle iron anchor piles are widely used. In particular, in the process of power transmission line construction, temporary pull wires play a crucial role, and their main function is to balance the tension of overhead lines after single-side hanging of conductors, and to ensure that the strain pole remains balanced and stable during the tightening operation. If temporary pull wires are not set during the tightening operation, it is extremely likely to cause the accident of broken pole. Therefore, in various construction scenarios such as replacement of rusty pull wires, pole tower stringing, pole tower erection and emergency repair of pole tower erection, temporary pull wires need to be erected to ensure the safety and reliability of construction operation.

[0003] At present, the main fixing method of temporary pull wires widely used in field construction is angle iron pile fixing, which uses angle iron as pile anchor and has the advantages of simple structure and easy portability. However, after the temporary pull wire device is used up, the angle iron pile fixing the pull wire needs to be recycled. Since most of the angle iron piles are buried below the ground, the pulling-out process is quite tricky. The traditional method usually relies on the left and right wheel hammers to impact the angle iron pile, so that it is loosened and pulled out. This method not only consumes time and effort, but also has a great labor intensity.

[0004] In view of the above problems, several practical new patent products have appeared on the market, aiming to amplify the pulling-out force through the principle of lever, gourd or jack, etc. to improve the pulling-out efficiency. However, these patent products all face some common problems in actual application. First, the device for gripping the angle pile needs to be fixed and installed artificially, and needs to be repeatedly installed and disassembled during use, which saves effort to some extent, but does not significantly reduce the time consumption. Second, these patent products are mainly suitable for vertically installed anchor piles, but in fact, anchor piles are mostly inserted obliquely into the soil, and oblique output should be used when pulling out to be effective, but the existing patent products are still insufficient in oblique output. Finally, these patent products have relatively complex structure and bulky size, and in the case of small number of temporary anchor piles, the efficiency improvement is not obvious compared to the labor of carrying tools. SUMMARY

[0005] The utility model relates to a practical new device for pulling out angle iron anchor piles, which aims to provide a pulling-out tool with simple structure, low cost, easy portability and firm structure, and especially solves the problems of complex operation of anchor pile gripping components and poor applicability in the prior art.

[0006] To achieve the above object, the utility model adopts the following technical scheme:

[0007] The utility model discloses a structure mainly includes the chuck, T character pry lever and steel pipe three parts. The design of chuck is the core of the utility model, and it is opened a deep groove, and the quick sleeve is convenient for angle steel edge. When prying up, chuck is tight through the twist action and is bitten angle steel edge, realizes fixed effect, when the lever is reset, chuck is loosened automatically, and under the action of gravity, slide down, realize the effect of regrasping down.

[0008] Further, the deep groove of the chuck is punched into a circular arc shape with an angular edge, and has a sawtooth-shaped corrugation. This design not only increases the contact area between the chuck and the angle steel edge, but also increases the friction force through the sawtooth-shaped corrugation, so that the chuck is more firm and reliable when biting the angle steel.

[0009] In addition, two annular rings are welded on one side of the chuck, and the two annular rings are used to sleeve into the T-shaped pry bar. The T-shaped end of the T-shaped pry bar can be pressed onto the ground to provide a stable fulcrum for prying. The other end of the pry bar is sleeved into the long steel pipe, and the length of the lever is increased to increase the prying force.

[0010] The utility model has the beneficial effects mainly embodied in the following aspects:

[0011] 1. Simple structure: the device of the utility model is composed of a chuck, a T-shaped pry lever and a steel pipe, which is simple in structure and easy to manufacture and maintain.

[0012] 2. Low cost: due to the simple structure, the material cost is low, so that the device of the utility model has a competitive advantage in price.

[0013] 3. Easy to carry: the device of the utility model is small in size and light in weight, easy to carry and transport, suitable for various construction environments.

[0014] 4. Firm structure: the deep groove, circular arc-shaped angular edge and sawtooth-shaped corrugation design of the chuck, as well as the cooperation of the T-shaped pry bar and the steel pipe, make the device of the utility model have high stability when clamping the anchor pile.

[0015] 5. Large lever force: through the cooperation of the T-shaped pry bar and the steel pipe, the lever force of prying can be increased, and the construction efficiency can be improved.

[0016] 6. Strong applicability: the device of the utility model is suitable for various angle iron anchor piles with various widths and various inclination angles, and has strong universality and adaptability. BRIEF DESCRIPTION OF DRAWINGS
