Description

Technical Field

[0001] The utility model relates to the technical field of bolt installation, and particularly relates to a bolt positioning assembly. Background Art

[0002] A bolt is a tensile member that penetrates deep into the formation and consists of a rod body, an anchorage section, and a free section. The rod body is the main part for transmitting loads. One end is tightly combined with the surrounding rock and soil through the anchorage section, and the other end is connected to the engineering structure. The free section is used to apply prestress. Among them, a slope refers to a sloping surface formed by natural terrain or artificial excavation and filling, which is commonly found in engineering activities such as road construction, railway subgrade, water conservancy dams, mining, and urban construction. The stability of the slope directly affects engineering safety and the surrounding environment. During slope protection, it is often necessary to insert bolts to increase the stability of the soil body and prevent collapse or sliding.

[0003] When installing the existing bolts, it is necessary to screw or insert them into the formation. Currently, some rely on manual holding to ensure stability, but the accuracy of manual holding is limited, and it is time-consuming and laborious. Some use positioning knot devices for limiting, but their structural flexibility is poor, and it is difficult to adapt to the positioning and installation of bolts with different lengths and diameters.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0025] Figures 1 - 3 These are all overall structural schematic diagrams of the present utility model. As shown in the figure, the anchor rod positioning assembly includes an upper positioning member and a lower positioning member. The upper positioning member and the lower positioning member are distributed up and down, and a lifting structure is provided between the upper positioning member and the lower positioning member. The upper positioning member can approach or move away from the lower positioning member through the lifting structure to adapt to the positioning requirements of anchor rods of different lengths.

[0026] Among them, both the upper positioning member and the lower positioning member include a first arc-shaped plate 1 and a second arc-shaped plate 2. The first arc-shaped plate 1 and the second arc-shaped plate 2 are arranged oppositely, and convex plates 7 are fixed at both ends of the first arc-shaped plate 1 and the second arc-shaped plate 2. Threaded fasteners are provided on the two opposite convex plates 7, and a spring 10 is connected between the two opposite convex plates 7. The threaded fasteners cooperate with the spring 10 to adjust the distance between the first arc-shaped plate 1 and the second arc-shaped plate 2, so as to adapt to the positioning requirements of anchor rods of different diameters.

[0027] Refer to Figure 1 and Figure 3 As shown, the lifting structure includes:

[0028] A convex block 3, which is fixed to the outer walls of the first arc-shaped plate 1 and the second arc-shaped plate 2;

[0029] A threaded rod 4, the bottom end of the threaded rod 4 is connected to the upper end surface of the lower convex block 3, and the threaded rod 4 penetrates through the upper convex block 3;

[0030] An upper threaded sleeve 5 and a lower threaded sleeve 6, both the upper threaded sleeve 5 and the lower threaded sleeve 6 are screwed onto the outside of the threaded rod 4, and the upper threaded sleeve 5 and the lower threaded sleeve 6 are located above and below the upper convex block 3 respectively.

[0031] Refer to Figure 1 and Figure 2 As shown, the threaded fasteners include a screw 8 and a fastening nut 9. The screw 8 penetrates through the two opposite convex plates 7, and the fastening nut 9 is screwed onto the outside of the screw 8. The spring 10 is sleeved on the outside of the screw 8.

[0032] Through the above technical solutions:

[0033] Before installing the anchor rod on the slope, first adjust the distance between the first arc plate 1 and the second arc plate 2 according to the diameter of the anchor rod. When adjusting, just rotate the fastening nut 9. Then, make the lower positioning member contact the soil layer where the anchor rod is to be inserted downward. Subsequently, the anchor rod to be inserted downward can pass through between the first arc plate 1 and the second arc plate 2 at the upper end, and then pass through between the first arc plate 1 and the second arc plate 2 at the lower end. The upper positioning member and the lower positioning member at the upper and lower ends are used for positioning, which can position the anchor rod vertically, ensure the verticality of the downward insertion of the anchor rod, prevent skew, and avoid potential structural safety hazards caused by deviation.

[0034] Among them, by rotating the upper thread sleeve 5 and the lower thread sleeve 6 outside the threaded rod 4, the distance between the upper positioning member and the lower positioning member can be changed, which is convenient for quickly adjusting according to anchor rods of different lengths and is relatively flexible and convenient.

[0035] Secondly, the positioning component has a simple structure and is also convenient for overall assembly. The first arc plate 1 and the second arc plate 2 can be quickly docked through threaded fasteners. When installing the upper positioning member, just first rotate the lower thread sleeve 6, then symmetrically put the first arc plate 1 and the second arc plate 2 at the upper end on the two threaded rods 4, and then rotate the upper thread sleeve 5.

[0036] Furthermore, convex portions are integrally formed on the outer walls of both the upper thread sleeve 5 and the lower thread sleeve 6.

[0037] Specifically, the convex portions are used to rotate the upper thread sleeve 5 or the lower thread sleeve 6, which is convenient for the staff to apply force.

[0038] Furthermore, arc-shaped silica gel strips 13 are fixed on the inner walls of both the first arc plate 1 and the second arc plate 2, and the inner walls of the arc-shaped silica gel strips 13 are smooth.

[0039] Specifically, the arc-shaped silica gel strips 13 have strong wear resistance, and the arc-shaped silica gel strips 13 with smooth inner walls have small friction, which is beneficial to the downward movement of the anchor rod when the anchor rod is inserted downward.

[0040] In addition, fixing blocks 11 are fixed on the outer walls of both the first arc plate 1 and the second arc plate 2 at the lower end. Insertion piles 12 are inserted through the fixing blocks 11, and downward insertion tips are integrally formed at the bottom ends of the insertion piles 12.

[0041] Through the above, after the lower positioning member contacts the soil layer where the anchor rod is to be inserted downward, the insertion pile 12 can be inserted through the fixing block 11, and the insertion pile 12 provided with the downward insertion tip is inserted into the soil layer, which can effectively ensure the stability of the bottom-end positioning and thus improve the accuracy of the anchor rod installation.

[0042] Only some exemplary embodiments of the present utility model have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
