Description

A fast dismantling push rod for drilling stress gauge installation

technical field

The utility model belongs to the technical field of mine pressure monitoring, and in particular relates to a quickly dismantled drilling stress gauge installation push rod.

Background technique

When performing on-site mine pressure monitoring, it is necessary to push the mine pressure monitoring equipment such as borehole stress gauges to the bottom of the borehole in time to monitor the stress changes of the overlying strata, so as to obtain reliable data. Commonly used drilling stress gauges are equipped with push rods, and the multi-section rod bodies are connected by screws and nuts. Because tools such as pliers and wrenches are needed to tighten the nuts, it is often difficult to quickly install and disassemble the push rod. At the same time, when the rods are connected, it is difficult to align the circular holes on the two rods to form a through hole for the screw to pass through, causing the push rod Inconvenient to install and disassemble. Coupled with the fact that the connecting screws are sometimes rusted and damaged and the push rod cannot be disassembled, it is difficult to install the borehole stress gauge in the limited space of the underground roadway.

Contents of the invention

Based on this, the technical problem to be solved by the utility model is: for the installation of the push rod of the current drilling stress gauge, the connecting nut needs to be tightened with pliers, and the circular holes on the two sections of the rod body are difficult to align to form a through hole so that the screw passes through and because In order to solve problems such as damage to the connecting screw and failure to disassemble the push rod, a quick-dismantling drilling stress gauge installation push rod is provided, so that the push rod can be installed and disassembled quickly and conveniently, and the drilling stress gauge can be sent to the bottom of the borehole in time.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is as follows: a quick-disassembly drilling stress gauge installation push rod, which includes a plurality of rod bodies, and the two ends of the rod body include joints and interfaces; the joints are protruding square bodies , which is a part of the cylindrical rod body. There is a circular hole on one side of the joint. The interior of the joint includes a top wire, a spring and a positioning pin. The positioning pin passes through the circular hole. The spring is installed at the lower part of the positioning pin and is installed on the joint through the top wire. In the protruding square body; the interface is a square hole opened at the other end of the rod body, and a circular pin hole is opened on one side wall of the square hole, and the diameter of the pin hole is larger than that of the positioning pin. The utility model describes a quick-detachable drilling stress gauge installation push rod, which is composed of a plurality of rod bodies, which are connected in a convenient and quick-detachable manner through the joints and interfaces at both ends of the rod bodies.

Beneficial effects of the utility model: the utility model realizes fast and convenient installation and disassembly of the push rod for drilling stress gauges, without the need for other auxiliary tools such as pliers, and is easy to operate and improves work efficiency.

detailed description

The embodiment of the utility model will be further described below in conjunction with the accompanying drawings.

Embodiment 1, a quick-detachable drilling stress gauge installation push rod, as shown in Figure 1, Figure 2, and Figure 3, mainly includes a rod body 6 and joints 2 and interfaces 7 at both ends of the rod body 6, and can be quickly disassembled. Connection composition; the joint 2 is a protruding square body, which is a part of the cylindrical rod body 6. The top wire 4 and the positioning pin 1 inside the joint 2 are permanently fixed inside the joint 2 through the spring 3, and the positioning pin 1 is connected from one side of the joint 2. There is a circular hole pierced through; the interface 7 is a square hole opened at the other end of the rod body 6, and a circular pin hole 5 is opened on the side wall of the hole, and the diameter of the pin hole 5 is larger than the diameter of the positioning pin 1; Pin 1 inserts joint 2 into interface 7, and positioning pin 1 passes through pin hole 5 to realize quick installation of the push rod; after installation, press positioning pin 1 to pull joint 2 out of interface 7 to realize quick disassembly of the push rod .

Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above-mentioned examples, and changes, modifications, additions or replacements made by those skilled in the art within the essential scope of the present utility model are also acceptable. Should belong to the protection scope of the utility model.
