Description

Technical Field

[0001] The utility model relates to the technical field of pipe seam anchor rods, in particular to a novel stretchable pipe seam anchor rod. Background Art

[0002] The pipe-slit anchor is a new type of anchor that is full-length anchored and actively reinforces the surrounding rock. Its three-dimensional part is a high-strength steel pipe with longitudinal slits. When installed in a borehole slightly smaller than the pipe diameter, it can immediately apply radial pressure to the hole wall and friction to prevent the surrounding rock from sliding down within the entire length. In addition, the supporting force of the anchor tray plate puts the surrounding rock in a three-dimensional stress state and achieves rock stratum stability. In the case of blasting vibration surrounding rock anchor displacement, the later anchoring force is significantly increased. When the surrounding rock undergoes significant displacement, the anchor does not lose its support resistance. It has better characteristics than the expansion shell anchor.

[0003] At present, after the existing pipe seam anchor rods are installed, workers need to manually hold the anchor rods and rotate them, which consumes a lot of physical strength during the rotation process, and if the pressure is too high when tightening with nuts, it is easy to damage the support plate. Utility Model Content

[0004] The utility model aims to provide a novel stretchable pipe seam anchor rod. The existing pipe seam anchor rod needs to be manually held and rotated after installation, which consumes physical strength during the rotation process, and if the pressure is too high when tightening with a nut, it is easy to damage the support plate.

[0005] In order to achieve the above-mentioned purpose, a new type of stretchable pipe seam anchor is provided, including: an anchor body, a support plate is installed on the outside of the anchor body, a plurality of positioning holes are opened on the side wall of the support plate, a support platform is installed on the outside of the anchor body, a plurality of positioning rods are arranged on the side wall of the support platform, a connecting head is arranged at one end of the anchor body, a socket is opened through the middle of the connecting head, and an insertion rod is installed in the middle of the socket.

[0006] According to the novel stretchable pipe seam anchor, a nut is installed on the outside of the connecting head, and a pad is installed on the side wall of the support platform.

[0007] According to the novel stretchable pipe seam anchor rod, a rod head is arranged at the front end of the anchor rod body, and a pipe seam is opened at the outer side of the anchor rod body.

[0008] According to the novel stretchable pipe seam anchor, the plurality of positioning rods respectively cooperate with the positioning holes.

[0009] The above scheme has the beneficial effects: the utility model utilizes the insertion rod and the insertion hole to cooperate, and the anchor rod can be driven to rotate under the cooperation of the insertion rod, which is more convenient and saves physical effort when rotating, and utilizes the support platform and the pad to cooperate, and utilizes the positioning rod and the positioning hole to cooperate to facilitate the limiting of the support plate, so that the support plate remains stable, which is more convenient during installation and will not slide.

[0010] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0020] Reference Figure 1-5The utility model embodiment is a novel stretchable pipe seam anchor, which includes: an anchor body 1, a support plate 4 is installed outside the anchor body 1, and a plurality of positioning holes 10 are opened on the side wall of the support plate 4. The positioning holes 10 cooperate with the positioning rods 11 to keep the support platform 5 stable and avoid loosening. A support platform 5 is installed outside the anchor body 1, and a plurality of positioning rods 11 are arranged on the side wall of the support platform 5. A connecting head 8 is arranged at one end of the anchor body 1, and a plug hole 9 is opened through the middle of the connecting head 8. An insertion rod 12 is installed in the middle of the plug hole 9, and the insertion rod 12 is used to facilitate the staff to manually rotate the anchor body 1.

[0021] A nut 7 is installed on the outside of the connecting head 8, and a pad 6 is installed on the side wall of the support platform 5. The pad 6 cooperates with the support platform 5 so that the nut 7 will not be damaged when squeezing the support platform 5. A rod head 2 is provided at the front end of the anchor rod body 1, and a pipe seam 3 is opened on the outside of the anchor rod body 1. Multiple positioning rods 11 cooperate with the positioning holes 10 respectively.
