Description

Technical Field

[0001] This utility model relates to the field of slope anchor construction technology, specifically to a slope anchor centering and positioning support frame. Background Technology

[0002] Slope anchors are an engineering measure used to reinforce and stabilize soil and rock slopes, tunnel surrounding rock, or rock masses around underground caverns. They enhance structural stability and prevent landslides or other forms of instability by transferring force to more stable and solid strata. The construction process involves drilling anchor holes in the slope, grouting them, and then inserting the anchors into the holes. Because the diameter of the anchor is smaller than the inner diameter of the anchor hole and its length is relatively long, it is necessary to weld positioning and supporting steel bars onto the anchor at regular intervals to keep the anchor body in the center of the hole. However, this welding method damages the anchor body structure, especially near the weld. The high-temperature welding creates a heat-affected zone at the weld joint, which leads to a decrease in anchor hardness, an increase in brittleness, and a weakening of the anchor's mechanical properties.

[0003] In view of this, a design or technical improvement is proposed to solve the above problems.

[0004] The above content is only used to help understand the technical solution of this utility model and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a slope anchor rod centering and positioning support frame.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] The slope anchor bolt centering and positioning support frame includes a clamping plate. The clamping plate has a U-shaped groove for locking the anchor bolt. Movable grooves are provided on both sides of the U-shaped groove. A retaining ring is rotatably installed in one of the movable grooves to lock the anchor bolt in conjunction with the clamping plate. The free end of the retaining ring has a pin hole and can be rotatably locked into the movable groove on the other side. The ring is then locked by a pin rod provided on the corresponding side. Positioning arms for supporting the inner wall of the anchor hole are evenly distributed on the outer end of the clamping plate.

[0008] Furthermore, the card plate is provided with a through hole for the pin to pass through, and a first limiting groove is provided on the inner wall of the through hole. The pin is provided with a limiting plate that limits its sliding within the first limiting groove.

[0009] Furthermore, the positioning arm includes a fixed sleeve plate disposed on the card plate, a movable support plate that is telescopically sleeved within the fixed sleeve plate, and an adjustment component disposed on the card plate for adjusting the telescopic amount of the movable support plate.

[0010] Furthermore, the adjustment assembly includes an adjustment plate that slides relative to the retaining plate, connecting rods evenly distributed on the adjustment plate with one end hinged to the adjustment plate and the other end hinged to the movable support plate, and an adjustment unit for changing the relative position of the adjustment plate and the retaining plate; the fixed sleeve plate is provided with a second limiting groove for the connecting rod and the movable support plate to slide relative to each other.

[0011] Furthermore, the adjusting plate is provided with two sets of ear plates, and a limiting rod and a threaded rod provided on the clamping plate are respectively movably connected to the two sets of ear plates. An adjusting nut is threaded onto the threaded rod.

[0012] Furthermore, the movable support plate has an installation groove on the side away from the fixed sleeve plate, and a roller is rotatably installed in the installation groove.

[0013] Furthermore, rubber pads are provided on the inner sides of the card plate and the buckle.

[0014] Furthermore, the pin hole has a tapered opening with a gradually increasing inner diameter at one end near the pin rod.

[0015] Compared with the prior art, the beneficial effects of this solution are as follows: This utility model sets a clamping plate that can be engaged with the anchor rod and a buckle set on the clamping plate to lock the anchor rod, and coordinates with positioning arms evenly distributed on the outside of the clamping plate to support the inner wall of the anchor hole, so that the whole can be easily clamped on the anchor rod and extend into the anchor hole to form support, keeping the anchor rod in the center position, thereby avoiding the structural damage to the anchor rod itself caused by welding support steel bars.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figure 1-7 The slope anchor bolt centering and positioning support frame shown includes a clamping plate 1. The clamping plate 1 has a U-shaped groove 11 for anchor bolt engagement. Movable grooves 12 are provided on both sides of the U-shaped groove 11. A retaining ring 13, which engages with the clamping plate 1 to lock the anchor bolt, is rotatably installed in one of the movable grooves 12. A pin hole 14 is provided on the free end of the retaining ring 13, which can be rotatably engaged into the movable groove 12 on the other side. Positioning arms 16 for supporting the inner wall of the anchor hole are evenly distributed on the outer end of the clamping plate 1. The clamping plate 1 has a through hole 2 for the pin rod 15 to pass through, and a first limiting groove 21 is provided on the inner wall of the through hole 2. The pin rod 15 is limited within the first limiting groove 21. The sliding limiting plate 22 is opened by rotating the buckle 13, which then clamps the clamping plate 1 onto the outer surface of the anchor rod. Next, the buckle 13 is rotated to fasten the anchor hole, and the pin rod 15 is inserted into the pin hole 14 for pin locking, thereby conveniently fixing the entire device to the anchor rod. In this way, a device is clamped at certain intervals on the anchor rod. Then, after the anchor rod is inserted into the anchor hole, the positioning arm 16 on the clamping plate 1 provides support to the inner wall of the anchor hole, thereby positioning the anchor rod in the center position. This device avoids the damage to the rod structure caused by welding steel bars to the anchor rod and the time-consuming and labor-intensive welding work, improving work efficiency and ensuring construction quality.

[0027] Meanwhile, the support frame can also be used with steel pipes as inspection supports for pile holes. This mainly involves clamping multiple support frames onto the steel pipes to form an inspection support, then welding lifting rings onto the steel pipes and adjusting 16 supports to the inside of the pile hole. Then, a crane is used to lower the inspection support into the pile hole. When it can be lowered smoothly, it indicates that the diameter of the pile hole is equal and the verticality meets the requirements. When the inspection support encounters obstruction, it indicates that the pile hole may have problems such as reduced diameter, tilting, or collapse. This process is used to determine whether the pile hole is qualified.

[0028] In one embodiment, the positioning arm 16 includes a fixed sleeve 3 disposed on the clamping plate 1, a movable support plate 31 telescopically sleeved within the fixed sleeve 3, and an adjustment assembly disposed on the clamping plate 1 for adjusting the telescopic amount of the movable support plate 31. The adjustment assembly includes an adjustment plate 4 that slides relative to the clamping plate 1, connecting rods 41 evenly distributed on the adjustment plate 4 with one end hinged to the adjustment plate 4 and the other end hinged to the movable support plate 31, and an adjustment unit for changing the relative position of the adjustment plate 4 and the clamping plate 1. The fixed sleeve 3 is provided with a connection for the connecting rod 41 and the movable support plate 31. The second limiting groove 42 of the hinged part limits the sliding. The adjusting plate 4 is provided with two sets of ear plates 43. The two sets of ear plates 43 are respectively movably connected to the limiting rod 44 and the threaded rod 45 set on the clamping plate 1. The threaded rod 45 is threaded with the adjusting nut 46. By rotating the adjusting nut 46, the adjusting plate 4 moves relative to the clamping plate 1. Then, the adjusting plate 4 drives the movable support plate 31 to extend from the fixed sleeve plate 3 through the connecting rod 41, so that the positioning arm 16 can be lengthened, thereby adapting to anchor holes with different inner diameters and improving the applicability of the device.

[0029] In one embodiment, the movable support plate 31 has an installation groove 32 on the side away from the fixed sleeve plate 3. A roller 33 is rotatably installed in the installation groove 32. The roller 33 makes rolling contact with the inner wall of the anchor hole, thereby reducing the resistance of the anchor rod being inserted into the anchor hole and improving construction efficiency.

[0030] In one embodiment, rubber pads 5 are provided on the inner sides of the clamping plate 1 and the buckle 13. The pin hole 14 has a tapered opening 6 with a gradually expanding inner diameter at one end near the pin rod 15. When the pin rod 15 is inserted into the pin hole 14, it first enters the tapered opening 6 and drives the pin hole 14 and the pin rod 15 to align by abutting the inclined surface of the tapered opening 6, thereby facilitating the docking of the pin rod 15 and the pin hole 14. At the same time, during the process of the pin hole 14 and the pin rod 15 gradually aligning, the rubber pads 5 on the inner side of the buckle 13 and the clamping plate 1 will be squeezed and deformed, thereby making the anchor rod clamp more secure. It also makes the device have a certain function of adapting to the outer diameter error of the anchor rod clamping.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
