[0026] Embodiment one

[0027] The embodiment provides an assistant installation device for a bolt. Specifically, please refer to Figures 1 to 4 , Figure 1This is a schematic diagram of the auxiliary bolt installation device provided in this embodiment; Figure 2 This is a schematic diagram of the structure in which the bolt to be installed is loaded inside the first sleeve, as provided in this embodiment; Figure 3 This is a specific example diagram of the limiting groove provided in this embodiment; Figure 4 for Figure 3 The diagram shows the structure of the matching bolt to be installed corresponding to the limiting groove. From... Figures 1 to 4 As can be seen, the auxiliary installation device 1 includes a sleeve assembly 11 and a pushing assembly 12 disposed in the sleeve assembly 11; the sleeve assembly 11 includes a first sleeve 111 for loading the bolt 2 to be installed and a second sleeve 112 fixedly connected to the first sleeve 111, wherein the length extension direction of the first sleeve 111 is the same as the length extension direction of the second sleeve 112; the pushing assembly 12 is configured to push the bolt 2 to be installed to move along the length extension direction of the sleeve assembly 11.

[0028] Therefore, the bolt auxiliary installation device provided in this embodiment loads the bolt 2 to be installed in the first sleeve 111 and provides support for the first sleeve 111 through the second sleeve 112. The length extension direction of the first sleeve 111 is the same as that of the second sleeve 112, so that the sleeve assembly 11 can play a good guiding role for the subsequent pushing assembly 12 to push the bolt 2 to be installed to the bolt hole. By setting the pushing assembly 12 in the sleeve assembly 11, the pushing assembly 12 can push the bolt 2 to be installed in the first sleeve 111 to move along the length extension direction of the sleeve assembly 11. After aligning the screw 21 of the bolt 2 to be installed with the bolt hole, the pushing assembly 12 can lift the bolt 2 to be installed to the bolt hole in the high-altitude construction area. Using the bolt auxiliary installation device provided in this embodiment in high-altitude construction can not only reduce the risk of bolts falling from heights, but also reduce the labor intensity and installation time of high-altitude workers. It can also effectively solve the problem of inconvenient manual installation of bolts in narrow spaces, thereby ensuring construction safety and improving installation efficiency.

[0029] For example, in some embodiments, the bolt to be installed 2 can be a spline head torque shear type high-strength bolt. The workers below can place the bolt to be installed 2 in the first sleeve 111 with the bolt head 22 facing down. After aligning the screw 21 of the bolt to be installed 2 with the bolt hole to be installed, the push assembly 12 is used to lift the bolt to be installed 2 to the bolt hole to be installed in the high-altitude construction area.

[0030] Preferably, the top of the first sleeve 111 is open and hollow, the bottom of the first sleeve 111 is provided with a bottom plate 1112, a through hole 11121 is formed in the bottom plate 1112 for the push assembly 12 to pass through, and the second sleeve 112 is fixedly connected with the bottom plate 1112. In this way, the first sleeve 111 is open and hollow at the top, which facilitates loading of the to-be-installed bolt 2; the bottom plate 1112 is arranged at the bottom of the first sleeve 111, which facilitates fixed connection of the second sleeve 112; and the through hole 11121 is formed in the bottom plate 1112, which facilitates the push assembly 12 to pass through, so that the to-be-installed bolt 2 in the first sleeve 111 can be pushed.

[0031] Preferably, the push assembly 12 comprises a push plate 121 in the first sleeve 111 and a push rod 122 in the second sleeve 112, one end of the push rod 122 passes through the through hole 11121 and is fixedly connected with the push plate 121. In this way, the push plate 121 is arranged in the first sleeve 111, which can increase the contact area with the to-be-installed bolt 2, so that the to-be-installed bolt 2 can be pushed more stably; the push rod 122 is arranged in the second sleeve 112, so that the to-be-installed bolt 2 can be jacked up.

[0032] Preferably, a handle is arranged at one end of the push rod 122 away from the push plate 121. In this way, the operator below can push the to-be-installed bolt 2 more stably.

[0033] Further, the length of the push rod 122 is greater than the sum of the lengths of the first sleeve 111 and the second sleeve 112. In this way, the to-be-installed bolt 2 in the first sleeve 111 can be completely jacked up to the top of the first sleeve 111, which facilitates the bolt head 22 of the to-be-installed bolt 2 to be close to the assembly in the air, so that the fixing effect can be enhanced.

[0034] It should be noted that, as can be understood by those skilled in the art, the overall length of the auxiliary installation device 1 can be reasonably set according to the actual application scenario.

[0035] Preferably, the length of the first sleeve 111 is less than the length of the to-be-installed bolt 2. In this way, the shank 21 of the to-be-installed bolt 2 can be exposed from the first sleeve 111, so that the to-be-installed bolt 2 can be quickly and accurately aligned with the to-be-installed bolt hole, which lays a good foundation for improving the installation efficiency.

[0036] Further, the first sleeve 111 and the second sleeve 112 are both cylindrical, and the outer diameter of the first sleeve 111 is greater than the outer diameter of the second sleeve 112. In this way, the outer diameter of the second sleeve 112 is less than the outer diameter of the first sleeve 111, so that the operator below can hold the second sleeve 112 more conveniently.

[0037] Exemplarily, the first sleeve 111 and the second sleeve 112 are both circular tubes, the bottom of the first sleeve 111 is integrally formed with a bottom plate 1112, the center of the bottom plate 1112 is provided with a through hole 11121, the diameter of the through hole 11121 is smaller than the inner diameter of the first sleeve 111. The second sleeve 112 is welded below the bottom plate 1112, the second sleeve 112 is provided with a cylindrical push rod 122, one end of the push rod 122 passes through the through hole 11121 and is welded and fixed with the bottom center of a circular push plate 121 provided in the first sleeve 111, and the diameter of the push plate 121 is the same as the inner diameter of the first sleeve 111. Thus, the push plate 121 can be more smoothly jacked up along the inner wall of the first sleeve 111.

[0038] Preferably, the first sleeve 111 is provided with a limiting structure to limit the circumferential rotation of the to-be-installed bolt 2. Thus, by providing the limiting structure in the first sleeve 111 to limit the circumferential rotation of the to-be-installed bolt 2, it is more convenient for the high-altitude worker to tighten the nut 4 with the to-be-installed bolt 2, thereby providing powerful assistance for bolt installation in high-altitude construction.

[0039] Exemplarily, the limiting structure includes a limiting groove 1111 provided on the inner wall of the first sleeve 111, the length extension direction of the limiting groove 1111 is the same as the length extension direction of the first sleeve 111; the limiting groove 1111 matches the outer circle of the bolt head 22 of the to-be-installed bolt 2 to limit the circumferential rotation of the to-be-installed bolt 2. Thus, by keeping the length extension direction of the limiting groove 1111 consistent with the length extension direction of the first sleeve 111, the to-be-installed bolt 2 can move along the length extension direction of the first sleeve 111; by matching the limiting groove 1111 with the outer circle of the bolt head 22 of the to-be-installed bolt 2, the circumferential rotation of the to-be-installed bolt 2 can be limited, thereby laying a foundation for the high-altitude worker to tighten the nut 4 with the to-be-installed bolt 2.

[0040] Please continue to see Figure 3 and Figure 4 Exemplarily, in some embodiments, if the to-be-installed bolt 2 is an external hexagonal bolt, the outer circle of the bolt head 22 of the to-be-installed bolt 2 is a hexagonal structure, and the limiting groove 1111 provided on the inner wall of the first sleeve 111 can be a hexagonal groove matched with the hexagonal structure to limit the circumferential rotation of the bolt head of the external hexagonal bolt.

[0041] Further, the axis of the sleeve assembly 11 is collinear with the axis of the pushing assembly 12. Thus, the pushing assembly 12 can more smoothly jack up the to-be-installed bolt 2 in the sleeve assembly 11.

[0042] Preferably, the sleeve assembly 11 and the pushing assembly 12 can be made of light metal material. Thus, the auxiliary installation device 1 can be more portable, the labor intensity of the operator below can be reduced, and the installation efficiency can be improved.

[0043] It should be noted that the specific type of light metal material is not limited in the present application. For example, in some embodiments, the light metal material can be aluminum alloy; in other embodiments, the light metal material can also be titanium alloy.

[0044] It should be noted that the above is only an example, and the present application does not limit the material of the sleeve assembly 11 and the pushing assembly 12. For example, in other embodiments, the material of the sleeve assembly 11 and the pushing assembly 12 can also be stainless steel.
