[0002] In the installation process of large machinery, steel structure engineering and heavy equipment, large bolt is often needed to be installed vertically to the specified position, such as equipment base fixing, pipeline flange connection, large rack assembly and other scenes. Such large bolt usually has the characteristics of large diameter and heavy weight.

[0003] The conventional installation method relies on manual operation, which has many problems and deficiencies. For example, manual operation is difficult, and in the installation process, workers need to hold heavy bolts upwardly to align with the threaded hole, which is laborious and difficult to work for a long time, and is prone to fatigue and operation errors. Moreover, the alignment accuracy is low, and the alignment accuracy of large bolt is high, but due to the effect of gravity, it is difficult to align accurately with the threaded hole when manually lifting, and it is easy to cause thread damage or even scrap.

[0004] Therefore, under the installation mode relying on manual operation, the technical problems of difficult manual operation and low alignment accuracy are generated. SUMMARY

[0012] Further, the auxiliary device for the vertical mounting bolt further comprises a support base, the support base is configured to support the conversion mechanism and isolate the conversion mechanism and the lifting mechanism on the conversion mechanism from the horizontal plane.

[0013] Further, the support base comprises a first support frame for supporting the conversion mechanism, and a connecting frame connected to the first support frame, the vertical height of the connecting frame is greater than that of the force rod and the sleeve.

[0014] Further, the first support frame is composed of at least three support rods connected end to end to form a cavity for accommodating the conversion mechanism, the conversion mechanism further comprises a disc arranged around the sleeve, the transverse width of the disc is greater than that of the first support frame, so that the disc can abut against the first support frame.

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] To better understand the purpose, structure, and function of this utility model, the following detailed description of an auxiliary device for vertically mounting bolts is provided in conjunction with the accompanying drawings.

[0025] For convenience, the direction along which the bolt extends will be referred to as "vertical", "perpendicular" or similar terms, and the direction perpendicular to "vertical" or "perpendicular" will be referred to as "horizontal", "horizontal" or similar terms.

[0026] Figure 1 The schematic diagram illustrates the overall structure of the auxiliary device for vertically mounting bolts according to this utility model. In such a way... Figure 1In the illustrated embodiment, the auxiliary device for vertically mounting the bolt includes a lifting mechanism 1 for receiving the bolt 10, and a conversion mechanism 2 that is selectively connected to the lifting mechanism 1 and is capable of applying a force to the lifting mechanism 1 in the vertical direction.

[0027] In this way, such as Figure 1 As shown, when bolt 10 needs to be installed, bolt 10 can be placed on lifting mechanism 1, and lifting mechanism 1 can be connected to conversion mechanism 2. At the same time, bolt 10 is kept coaxial with the hole to be installed (not shown in the figure).

[0028] At this time, as Figure 1 As shown, the conversion mechanism 2 applies a vertically upward force to the lifting mechanism 1, thereby driving the lifting mechanism 1 to move vertically upward, which in turn causes the lifting mechanism 1 to actuate the bolt 10 to move vertically upward. Simultaneously, during this process, a circumferential force is continuously applied to the bolt 10, causing it to continuously rotate and connect with the hole to be installed. This allows for convenient vertical installation of the bolt 10.

[0029] In one embodiment, such as Figure 1 As shown, the lifting mechanism 1 includes a tray 11 for vertically placing the bolt 10, and a force-bearing rod 12 disposed on the tray 11 and extending into the conversion mechanism 2 to receive the force output by the conversion mechanism 2. In this way, the force from the conversion mechanism 2 can be continuously transmitted along the force-bearing rod 12 to the tray 11, thereby causing the bolt 10 located on the tray 11 to move.

[0030] In one embodiment, such as Figure 1 As shown, the conversion mechanism 2 includes a sleeve 21, which is hollow to allow for the accommodation of the force-bearing rod 12. Additionally, an internal thread is provided along the inner wall of the sleeve 21.

[0031] In addition, such as Figure 1 As shown, an external thread is also provided on the outer wall of the force-bearing rod 12, which engages with the internal thread of the inner wall of the sleeve 21. In this way, when the force-bearing rod 12 rotates along the sleeve 21, the sleeve 21 will continuously apply a force to the force-bearing rod 12 in the vertical direction. Thus, the force-bearing rod 12 can move in the vertical direction.

[0032] In this configuration, such as Figure 1As shown, when bolt 10 needs to be installed, firstly, the force-bearing rod 12 is placed inside the sleeve 21, and the force-bearing rod 12 and sleeve 21 are engaged together by threads. At the same time, bolt 10 is placed vertically on tray 11, and bolt 10 is kept coaxial with the hole to be installed (not shown in the figure).

[0033] Then, while keeping the sleeve 21 stable, a circumferential force is applied to the tray 11, such that the direction of the applied force allows the force-bearing rod 11 to move vertically upward. During this process, the tray 11 will cause the force-bearing rod 12 to rotate along the sleeve 21.

[0034] During this process, the sleeve 21 continuously drives the force-bearing rod 12 to rotate vertically upwards, thereby causing the force-bearing rod 12 to drive the tray 11 to rotate vertically upwards, which in turn causes the tray 11 to actuate the bolt 10 to rotate vertically upwards. When the free end of the bolt 10, which is rotating vertically upwards, comes into contact with the hole to be installed (not shown in the figure), the bolt 10 will continue to move into the hole. Thus, the bolt 10 is connected to the hole to be installed.

[0035] In one embodiment, such as Figure 2 As shown, at least two clamping portions 111 are also provided on the tray 11, which are configured to allow a force to be applied to the bolt 10 in the circumferential direction. In this way, the bolt 10 mounted on the tray 11 can also be subjected to a force from the clamping portions 111. This allows the bolt 10 to be stably mounted on the tray 11. It should be noted that the force applied by the clamping portions 111 to the bolt 10 is perpendicular to the axis of the bolt 10.

[0036] According to a preferred embodiment of the present invention, such as Figure 2 As shown, the clamping part 111 includes a first clamping surface 1111 and a second clamping surface 1112 connected to the first clamping surface 1111 at a certain angle. In this embodiment, the angle is set to 120°.

[0037] It should be noted that, as Figure 2 As shown, the bolt 10 is configured as an octagonal bolt, such that when the bolt 10 is clamped, the first clamping surface 1111 and the second clamping surface 1112 are in close contact with the two adjacent surfaces of the bolt 10. In this way, the angle formed between the first clamping surface 1111 and the second clamping surface 1112 matches the angle formed by the two adjacent sides of the octagonal bolt. This further secures the bolt 10 to the tray 11.

[0038] In one embodiment, such asFigure 2 As shown, a connecting block 112 corresponding to each clamping part 111 is arranged on the tray 11, and a connecting rod 113 is arranged on each connecting block 112, which is configured to allow the connecting rod 113 to move in the transverse direction along the connecting block 112 and abut with the clamping part 111, so that the connecting rod 113 can selectively apply a force to the clamping part 111 in the transverse direction. In this way, the bolt 10 can be stably arranged on the tray 11. It should be noted that in the embodiment, the connecting block 112 is arranged in a ring mechanism and extends upward on the tray 11.

[0039] According to one preferred embodiment of the utility model, Figure 2 As shown, the connecting rod 113 is arranged as a threaded rod, and a threaded hole corresponding to the threaded rod is arranged on the connecting block 112, so that the connecting rod 113 can move in the transverse direction by rotating along the threaded hole, and the relative fixation between the connecting rod 113 and the threaded hole is allowed. It should be noted that the clamping part 111 is arranged on the tray 11 in a selective manner.

[0040] In this arrangement, as shown, Figure 2 When it is necessary to stably arrange the bolt 10 on the tray 11, the bolt 10 is first placed on the tray 11 in a perpendicular manner to the tray 11. At the same time, the clamping part 111 is placed on the tray 11, and the first clamping surface 1111 and the second clamping surface 1112 abut with the two edges adjacent to the bolt 10.

[0041] At this time, the connecting rod 113 is rotated and continuously moves towards the clamping part 111, so that the connecting rod 113 abuts with the clamping part 111. At the same time, in this arrangement, the connecting rod 113 can also be relatively fixed with the connecting block 112. Therefore, the clamping part 111 can stably clamp the bolt 10, so that the bolt 10 can be stably arranged on the tray 11.

[0042] According to one preferred embodiment of the utility model, Figure 2 As shown, the position of the connecting rod 113 arranged on the connecting block 112 corresponds to the connection between the end of the connecting rod 113 and the first clamping surface 1111 and the second clamping surface 1112. In this way, when the connecting rod 113 applies a force to the clamping part 111, the force can be transmitted to the first clamping surface 1111 and the second clamping surface 1112, respectively. Therefore, the bolt 10 can be further stably arranged on the tray 11.

[0043] In one embodiment, as shown, Figure 2As shown, the auxiliary device for vertical installation of the bolt further comprises a support base 3, which is arranged to be capable of bearing the conversion mechanism 2 and to isolate the conversion mechanism 2 and the lifting mechanism 1 located on the conversion mechanism 2 from the horizontal plane (the foundation and the like). In this way, the conversion mechanism 2 and the lifting mechanism 1 can avoid interference with the horizontal plane during movement, so that the conversion mechanism 2 and the lifting mechanism 1 can run smoothly.

[0044] In one embodiment, as shown in the drawings, Figure 2 As shown, the support base 3 comprises a first support frame 31 for bearing the conversion mechanism 2, and a connecting frame 32 connected with the first support frame 31, wherein the vertical height of the connecting frame 32 is arranged to be greater than the force rod 12 and the sleeve 21.

[0045] As shown in the drawings, Figure 2 As shown, the first support frame 31 is composed of at least three support rods 311 connected end to end, to jointly form a cavity for accommodating the conversion mechanism 2, wherein the conversion mechanism 2 further comprises a disc 22 arranged around the sleeve 21, and the lateral width of the disc 22 is arranged to be greater than the lateral width of the first support frame 31, so that the disc 22 can abut against the first support frame 31.

[0046] In this way, the conversion mechanism 2 can be arranged on the first support frame 31, and the conversion mechanism 2 and the lifting mechanism 1 can be located in the cavity of the conversion mechanism 2. Therefore, the conversion mechanism 2 can be arranged in a horizontal manner, and the conversion mechanism 2 and the lifting mechanism 1 can avoid interference with the horizontal plane during movement, so that the conversion mechanism 2 and the lifting mechanism 1 can run smoothly.

[0047] In one embodiment, as shown in the drawings, Figure 2 As shown, a gusset plate 33 is arranged in the cavity formed by each support rod 311 and fixed to the first support frame 31, and a through hole 331 is arranged on the gusset plate 33, which is arranged to cooperate with the sleeve 21 to position the sleeve 21 and the disc 22. In this way, the vertical relationship between the disc 22 and the bolt 10 can be ensured.

[0048] According to a preferred embodiment of the present application, as shown in the drawings, Figure 2As shown in the drawings, the first screw hole 332 is arranged on the base plate 33. Meanwhile, a second screw hole (not shown in the drawings) corresponding to the first screw hole 321 is arranged on the disc body 22. A connecting screw (not shown in the drawings) is arranged in the first screw hole 332 and the second screw hole in a selected manner, and the connecting screw is used to fix the disc body 22 and the base plate 33 together. In this way, the disc body 22 can be prevented from deviating from the base plate 33, thereby affecting the vertical relationship between the disc body 22 and the bolt 10.

[0049] In one embodiment, as shown in the drawings, Figure 2 The connecting frame 32 is composed of three connecting rods 321, and each connecting rod 321 is arranged at the connection of each support rod 311. In this way, the connecting strength between each support rod 311 can be reinforced. Meanwhile, each connecting rod 321 extends vertically downward, and the vertical height of each connecting rod 321 is greater than that of the force rod 12 and the sleeve 21. In this way, the connecting frame 32 can stably support the first support frame 31.

[0050] According to a preferred embodiment of the present application, as shown in the drawings, Figure 2 A second support frame 34 is arranged at the free end of the connecting frame 32, and the second support frame 34 is configured in the same structure as the first support frame 31 and is arranged corresponding to the first support frame 31. In this way, the second support frame 34 can reinforce the connecting frame 32, so that the connecting frame 32 further stably supports the first support frame 31.

[0051] According to a preferred embodiment of the present application, as shown in the drawings, Figure 2 A reinforcing rib 322 is arranged between each connecting rod 321, and the reinforcing rib 322 is arranged between each connecting rod 321 in an inclined manner. Specifically, one end of the reinforcing rib 322 is connected with the end of the connecting rod 321 and the first support frame 31, and the other end of the reinforcing rib 322 is connected with the end of the connecting rod 321 and the second support frame 34. In this way, the connecting frame 32 can be reinforced, so that the loosening of the connecting frame 32 does not affect the supporting effect of the first support frame 31.

[0052] In one embodiment, as shown in the drawings, ​ A traveling wheel 35 is arranged on the second support frame 34. In the present embodiment, the traveling wheel 35 is arranged in three and is located at the connection of the support rod 311. In this way, when the device needs to be moved, the traveling wheel 35 can roll along the horizontal plane (foundation and the like), thereby facilitating the carrying of the device.

[0053] The operation of the auxiliary device for vertically installing a bolt according to the utility model is as follows.

[0054] When the bolt 10 needs to be installed, first, the bolt 10 is placed on the tray 11 in a perpendicular manner. At the same time, the clamping part 111 is placed on the tray 11, and the first clamping surface 1111 and the second clamping surface 1112 abut against two edges adjacent to the bolt 10.

[0055] At this time, the connecting rod 113 is rotated, and the connecting rod 113 continuously moves towards the clamping part 111, so that the connecting rod 113 abuts against the clamping part 111. At the same time, in this arrangement, the connecting rod 113 can be relatively fixed with the connecting block 112. Thus, the clamping part 111 can stably clamp the bolt 10, so that the bolt 10 can be stably arranged on the tray 11.

[0056] Secondly, an acting force is applied to the device, so that the walking wheel 35 is driven to move until the bolt 10 is coaxial with a hole position (not shown in the figure) to be installed. At the same time, an acting force is applied to the tray 11 along the circumference, and the direction of the acting force can allow the force receiving rod 11 to move vertically upward. In this process, the tray 11 drives the force receiving rod 12 to rotate along the sleeve 21.

[0057] At this time, the sleeve 21 continuously drives the force receiving rod 12 to move vertically upward in a rotating manner, so that the force receiving rod 12 drives the tray 11 to move vertically upward in a rotating manner, and then the tray 11 drives the bolt 10 to move vertically upward in a rotating manner. When the free end of the bolt 10 moving vertically upward in a rotating manner contacts the hole position (not shown in the figure) to be installed, the bolt 10 continuously moves into the hole position. Thus, the bolt 10 is connected with the hole position to be installed.

[0058] When the installation is completed, an acting force is applied to the connecting rod 113 in a direction opposite to the above-mentioned acting force, so that the connecting rod 113 moves towards a direction away from the clamping part 111 until the connecting rod 113 is separated from the clamping part 111. Thus, the vertical installation of the bolt 10 is completed.

[0059] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model and are not limited. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the utility model, and all of them should be covered in the scope of the claims of the utility model.
