Description

Technical Field

[0001] This invention relates to the field of engineering technology, and in particular to a device that can assist in the stable installation of anchor cables. Background Technology

[0002] Anchor cables play a vital role in modern engineering, their function extending far beyond simply reinforcing and supporting structures; they directly impact the safety, stability, and overall quality of projects. From buildings to bridges, from tunnels to mines, anchor cables are widely used in various engineering projects.

[0003] However, in actual construction, the process of embedding anchor cables is often not easy. This is especially true when anchor cables need to be embedded in boreholes several meters deep, making the work particularly cumbersome. First, to ensure the anchor cables' stability, anchoring agents must be used to secure them. However, the outer shell of the anchoring agent is easily damaged and can be destroyed during the drilling process, especially on uneven rock borehole surfaces, making the insertion of the anchor cables particularly difficult and risking construction interruptions or a decline in project quality. Furthermore, because anchor cables are typically quite long, multiple anchoring agents need to be strung together, and the process of inserting and pushing them into place in deep boreholes is extremely time-consuming and labor-intensive.

[0004] The inconveniences and challenges encountered during construction directly impact the progress and quality of the project. Inefficient construction operations not only prolong the project cycle and increase costs, but may also result in the anchoring agent not being fully applied, thus affecting the stability and load-bearing capacity of the structure. Summary of the Invention

[0005] This invention aims to provide a device that assists in the secure installation of anchor cables. This device helps to isolate the anchor cable and anchoring agent from uneven, broken drill holes, allowing safe access to the bottom of the anchor hole for subsequent installation. The device features an outer and inner steel ring at the tail, which act as levers for workers to operate, enabling them to use less physical effort to smooth uneven drill holes and install the anchor cable. Furthermore, to enhance convenience, the device employs a segmented connection structure, facilitating easy installation and retrieval.

[0006] The technical solution provided by this invention is:

[0007] A device for assisting in the stable installation of anchor cables is provided. The device consists of multiple connecting sections, including A-section connecting section, B-section connecting section, and C-section connecting section. Several B-section connecting sections are connected between A-section connecting section and C-section connecting section. The connecting sections are detachably connected by a connecting system. Each connecting section includes an inner steel pipe and an outer steel pipe. The inner steel pipe is used to place the anchoring agent and anchor cable. Several through grooves are provided on the side wall of the inner steel pipe. Slopes are provided on both sides of the through grooves. Fastening keys are provided on the inner wall of the outer steel pipe corresponding to the through grooves. The fastening keys are connected to the inner wall of the outer steel pipe by fastening key springs. Several steel balls are provided between the inner steel pipe and the outer steel pipe.

[0008] The connection system includes a control part and a fixing part. The fixing part includes a rigid buckle, and the control part includes a protrusion, a fixed lever, a spring and a connecting handle. The rigid buckle and the protrusion are integrally formed and connected to different steel pipes. The protrusion is connected to the connecting handle through the spring and the fixed lever. There is a gap between the protrusion and the connecting handle for the rigid buckle to be engaged.

[0009] Section A connector has several spherical drill bits connected to one end of its outer steel pipe, and the other end is connected to Section B connector via a connection system. Both ends of Section B connector are connected to the connector via a connection system. One end of Section B connector is the control part, and the other end is the fixing part. Section C connector is connected to Section B connector at one end via a connection system. The other end has an outer steel ring connected to its outer steel pipe, and an inner steel ring connected to its inner steel pipe. The outer steel ring and the inner steel ring are connected by a connecting nut.

[0010] Furthermore, the connection system is applied to the outer steel pipe, and the inner steel pipes are connected by the cooperation of the plug and the slot.

[0011] Furthermore, the outer steel ring has a larger diameter than the outer steel pipe, and the inner steel ring has a larger diameter than the inner steel pipe.

[0012] Furthermore, several spherical drill bits are evenly fixed to the bottom circumference of one end of the outer steel pipe of section A connector.

[0013] The principle of the technical solution:

[0014] The connection system of this invention includes a protrusion, a rigid buckle, a spring, a connecting handle, and a fixed lever. The connecting handle is connected to the protrusion by the fixed lever and the spring in the middle. The protrusion is integrally formed and connected to the first end of the outer steel tube. When the two outer steel rings are connected, pressing the connecting handle on the side near the spring inserts the rigid buckle into the gap, thereby connecting and fixing the buckle to the connecting handle. The fixed lever provides stable connection and fixing capacity, and the spring compression provides hidden space for easy connection. The inner and outer steel tubes can rotate relative to each other. When the fastening key on the inner side of the outer steel tube is not rotated into the through groove, it is easy to put in the fastener and anchor cable. When the fastening key is rotated into the through groove, the fastening key can clamp and fix the fastener and anchor cable placed inside. After the connecting nut connects the outer steel ring and the inner steel ring, rotating the outer steel ring can make the whole device rotate. The spherical drill bit set at the front end can grind and break the uneven surface in the drill hole.

[0015] The beneficial effects of the technical solution are:

[0016] 1. This device can isolate the anchor cable and anchoring agent from the uneven and broken borehole, avoiding damage to the anchoring agent shell and leakage of the anchoring agent, and allowing the anchoring agent and anchor cable to safely reach the bottom of the borehole for subsequent installation.

[0017] 2. This device can cut off and grind the protruding wall of the drill hole while conveying the anchor cable and anchoring agent, creating a channel for anchor cable installation.

[0018] 3. This device simplifies the fixing of anchor cables and anchoring agents, eliminating the need for complicated operations and making it more labor-saving and convenient.

[0019] 4. When operating the outer steel ring for rotary drilling and finishing, it serves as a labor-saving lever, allowing installers to use less physical strength to finish uneven drill holes and install anchor cables. Attached Figure Description
