Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline processing equipment, in particular to a drilling device used for processing exhaust holes of an outer pipe of a thermal insulation composite pipe. Background Art
[0002] The thermal insulation composite pipe includes an inner pipe, an outer pipe and a foaming layer. The outer pipe is sleeved on the outside of the inner pipe, and the foaming layer is filled between the outer pipe and the inner pipe. When processing the thermal insulation composite pipe, firstly, the inner pipe and the outer pipe need to be processed separately, and then the inner pipe is placed in the outer pipe, wherein the outer diameter of the inner pipe is smaller than the inner diameter of the outer pipe; then, exhaust holes, i.e., foaming holes, are drilled on the outer pipe for exhaust. The exhaust holes are only drilled on the outer pipe and penetrate the outer pipe, and the inner pipe cannot be drilled; then, a support frame is placed between the inner pipe and the outer pipe to make the inner pipe and the outer pipe coaxial; finally, foaming powder is placed between the inner pipe and the outer pipe and both ends of the outer pipe are blocked, and the outer pipe is heated to make the foaming powder foam and fill the gap between the inner pipe and the outer pipe.
[0003] In the above processing, the tool for drilling the exhaust hole is an awl, and the awl is drilled through the outer tube manually. In winter, the outer tube will be very hard and cannot be drilled through manually. A hammer is needed to cooperate with the awl to drill holes, which is laborious and can easily puncture the inner tube. Utility Model Content

[0016] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.
[0017] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0020] A drilling device for processing exhaust holes on the outer tube of a thermal insulation composite pipe, such as Figure 1As shown, it includes a first supporting leg 1, a second supporting leg 2, a first handle 3, a first actuating rod 4, a second handle 5, a second actuating rod 6, a drill rod 7 and a conical drill bit 8.
[0021] A first leg 1 and a second leg 2 are hinged together, a first handle 3 is provided on the right side of the bottom side of the first leg 1 and a first actuating rod 4 is provided on the left side of the top side, a second handle 5 is provided on the left side of the bottom side of the second leg 2 and a second actuating rod 6 is provided on the right side of the top side, the first handle 3, the first actuating rod 4 and the second handle 5, the second actuating rod 6 form an X-shaped structure, a drill rod 7 is welded to the outer end surface of the first actuating rod 4, and a conical drill bit 8 is provided on the end of the drill rod 7 facing the second actuating rod 6.
[0022] The length of the first handle 3 is greater than that of the first operating rod 4 , and the length of the second handle 5 is greater than that of the second operating rod 6 .
[0023] The first handle 3 and the second handle 5 have the same length, and are covered with a plastic protective cover.
[0024] The first actuating rod 4 and the second actuating rod 6 have the same length.
[0025] The total length of the drill rod 7 and the conical drill bit 8 is not greater than the distance between the outer sides of the first actuating rod 4 and the second actuating rod 6 when they are closed.
[0026] The use process of the utility model is as follows:
[0027] In the normal state, the first action rod 4 and the second action rod 6 are closed;
[0028] When in use, the first handle 3 and the second handle 5 are separated to increase the distance between the first actuating rod 4 and the second actuating rod 6 until there is a distance between the drill rod 7, the conical drill bit 8 and the second actuating rod 6; the second actuating rod 6 is extended between the outer tube and the inner tube, and the first actuating rod 4 is located outside the outer tube; the first handle 3 and the second handle 5 are brought close to each other to reduce the distance between the first actuating rod 4 and the second actuating rod 6, thereby driving the drill rod 7 and the conical drill bit 8 to approach the direction of the second actuating rod 6, piercing the outer tube and processing the exhaust hole.
[0029] The drill rod 7 and the conical drill bit 8 are short and will not pierce the inner tube; the first handle 3 and the second handle 5 are long and more labor-saving. Because the lengths of the first action rod 4 and the second action rod 6 are fixed, the distance between the position of the exhaust hole and the end of the outer tube is also this distance. When a problem occurs when the thermal insulation composite pipe is buried underground, the position of the exhaust hole can be found immediately to troubleshoot the problem.
[0030] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
