Description

Technical Field

[0001] This utility model relates to the field of equipment hoisting technology, and in particular to a pin-insertion device. Background Technology

[0002] In the field of hydroelectric generator equipment maintenance, existing lower shaft hoisting operations present significant safety hazards and efficiency bottlenecks: traditional processes rely on a bridge crane suspending a suspended basket to transport workers to the upper shaft position at a high altitude, where the lower shaft is hoisted or dismantled manually by threading and pulling the lifting ropes. During this process, workers must move synchronously with the lower shaft, operating in a dynamic high-altitude environment, which poses extremely high safety risks; moreover, a single operation typically requires four people working together, resulting in high manpower input and long processing time.

[0003] In the hoisting of air supply pipes, existing technology uses the crane hook to directly hook the cable for lifting. However, the swaying of the hook makes it difficult to align the cable, often requiring a lot of time to adjust the position, resulting in low work efficiency. In addition, traditional pin-threading devices are mostly fixed structures. When faced with hole position deviations, it is necessary to forcibly adjust the position by shaking the crane cable. This is not only difficult to operate and time-consuming, but also difficult to adapt to complex scenarios, and has obvious application limitations.

[0004] Therefore, a pin-threading device is proposed. Utility Model Content

Detailed Implementation

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0035] Example 1, referring to Figures 1 to 3 This is the first embodiment of the present invention. This embodiment provides a pin-threading device, including a lifting rod 1; the end of the lifting rod 1 is provided with a lifting hole for connecting with the lifting cable of a crane.

[0036] The support frame 2 is rotatably mounted on the hanger 1. The support frame 2 is provided with a connecting plate 21, and the connecting plate 21 is provided with a through hole 212. The support frame 2 can rotate relative to the hanger 1 to adjust the alignment angle of the through hole 212 of the support frame 2.

[0037] The hydraulic rod 3 is mounted on the support frame 2, and the telescopic end of the hydraulic rod 3 is provided with an insertion end 31; the telescopic extension of the hydraulic rod 3 can control the insertion end 31 to be pulled out or inserted into the through hole 212.

[0038] The rotating mechanism 4 is mounted on the boom 1 and can control the rotation between the support frame 2 and the boom 1.

[0039] Specifically, the rotating mechanism 4 includes a drive motor 41 mounted on the boom 1, a gear 42 mounted on the output end of the drive motor 41, and a gear 22 mounted on the support frame 2. The operation of the drive motor 41 enables the gear 42 to rotate, thereby controlling the gear 22 to rotate. The gear 22 and the support frame 2 are fixedly connected.

[0040] Furthermore, gear 42 and gear disc 22 are meshed together, and a reducer 43 is provided on the drive motor 41. The drive motor 41 is connected to the gear 42 through the reducer 43. The torque output by the drive motor 41 is amplified by the reduction of the reducer 43, so as to control the rotation between the support frame 2 and the rod 1.

[0041] In use, the drive motor 41 controls the gear 42 to rotate. When the gear 42 rotates, it drives the gear disc 22 to rotate, which in turn causes the support frame 2 and the boom 1 to rotate relative to each other. By adjusting the angle of the insertion end 31 and the through hole 212, and coordinating with the crane to lower or raise the sling, the angle of the pin can be easily adjusted. Therefore, when hoisting and connecting the lower shaft of the hydro-generator, it is no longer necessary to lower the basket for the operator to hoist and connect. The position of the insertion end 31 and the through hole 212 can be adjusted remotely by the drive motor 41 via remote control. Preferably, a camera can be installed on the support frame 2 to facilitate remote control by the operator. In addition, when hoisting the air supply pipe, it is also not necessary for the operator to adjust the position of the cable. The hoisting efficiency can be improved by adjusting the position of the pin. When inserting the pin, the extension of the hydraulic rod 3 controls the insertion end 31 to be inserted into the through hole 212 to connect the cable or the hoisting part.

[0042] Example 2, refer to Figures 1-3 This is the second embodiment of the present invention. Unlike the previous embodiment, the rod 1 is provided with a support plate 11; the support plate 11 is fixedly disposed at the bottom end of the rod 1.

[0043] The toothed disc 22 is provided with a rotating sleeve 221, which is fixedly connected to the support frame 2; the rotating sleeve 221 and the toothed disc 22 are fixedly connected.

[0044] The rotating sleeve 221 and the support plate 11 are rotatably connected.

[0045] The boom 1 and the support frame 2 are rotatably connected by the rotating sleeve 221 and the support plate 11. Due to the increased contact and support area, the strength of the connection and the stability during rotation are increased.

[0046] Specifically, the support plate 11 is provided with a protruding edge 111; the rotating sleeve 221 is provided with a bearing edge 222; the cooperation between the protruding edge 111 and the bearing edge 222 can improve the stability of the connection between the hanger 1 and the support frame 2.

[0047] The outer wall along 222 and the inner wall protruding along 111 are rotatably connected.

[0048] Furthermore, ball bearings 5 ​​are provided between the bearing edge 222 and the support plate 11; the ball bearings 5 ​​are arranged in a circumferential array around the periphery of the rod 1. The ball bearings 5 ​​can roll between the bearing edge 222 and the support plate 11, and the rolling of the ball bearings 5 ​​can effectively reduce the friction between the rod 1 and the support frame 2 during rotation.

[0049] The rest of the structure is the same as in Example 1.

[0050] Example 3, referring to Figures 1-3 This is the third embodiment of the present invention. Unlike the previous embodiment, the support frame 2 is provided with a fixing frame 23, and the hydraulic rod 3 is fixed to the support frame 2 through the fixing frame 23.

[0051] Specifically, there are two connecting plates 21, and the two connecting plates 21 are symmetrically arranged on the support frame 2.

[0052] The space between the two connecting plates 21 is the connection space for the hoisted object.

[0053] Furthermore, the connecting plate 21 is provided with a ring 211, and a through hole 212 is formed on the ring 211.

[0054] The connecting plate 21 is provided with a reinforcing plate 24, and the reinforcing plate 24 is provided with a guide surface 241.

[0055] The rest of the structure is the same as in Example 2.

[0056] In use, the reinforcing plate 24 can increase the load-bearing capacity of the ring 211. If the connection part is rigid, such as the lifting lug at the shaft end, the guide surface 241 makes it easy to place the lifting lug at the shaft end between the two connecting plates 21. At this time, the rotating mechanism 4 controls the bearing frame 2 to rotate, aligning the insertion end 31 with the lifting hole of the lifting lug at the shaft end. The extension of the hydraulic rod 3 causes the insertion end 31 to be inserted into the through hole 212 on the connecting plate 21 on the opposite side. The insertion end 31 serves as a load-bearing structure, and together with the crane, the lifting rod 1 is lifted, thereby lifting the object being lifted.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
