Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering maintenance technology, specifically to a tool for the installation and maintenance of mechanical equipment in hydropower stations. Background Technology

[0002] During the installation and maintenance of hydropower station machinery, it is common to encounter situations where large torque is required but space constraints prevent the use of medium to large-sized machinery. A tool suitable for small spaces, possessing both an efficient force transmission mechanism and a large load-bearing capacity, can solve this problem. This tool utilizes the principle of a threaded helix and features a simple structure, small size, and easy portability. It can address the maintenance and installation work requiring large torque in confined spaces encountered during the installation and maintenance of hydropower station machinery. It can also provide load-bearing and support functions during simple parts processing and installation. However, it cannot be used in conjunction with modern power tools and requires manual operation, resulting in lower efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed and easy-to-use tool for the installation and maintenance of hydropower station mechanical equipment, which can effectively solve the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: It comprises:

[0005] The spiral seat consists of two spiral seats arranged symmetrically on the left and right. Each spiral seat has a spiral rod screwed into its interior by a thread, and an abutment seat is fixed to the top of each spiral rod.

[0006] The base consists of two bases, which are respectively fixed to the outer bottom wall of the spiral seat. Each base has a connecting frame inside, and the connecting frame is arranged in an "L" shape. The horizontal plates of the connecting frames on both sides are arranged in an alternating manner, and the adjacent sides of the horizontal plates of the connecting frames abut against each other.

[0007] The connecting column is provided with a threaded hole. The connecting column is inserted through and into one end of the two connecting frames that are in contact. The upper and lower ends of the connecting column are exposed on the outside of the connecting frames respectively. The connecting column is connected to the connecting frames through an angle adjustment mechanism.

[0008] The position adjustment mechanism consists of two parts, which are respectively installed in the base on both sides and are connected to the vertical plate of the connecting frame.

[0009] The above technical solution involves fixing the connecting column to the housing of the mechanical equipment with bolts. Then, according to the required support position, the angle adjustment mechanism drives the connecting frames on both sides to rotate. The connecting frames drive the base to rotate, and the base drives the screw seat to rotate to a suitable angle. Then, the position adjustment mechanism drives the connecting frame to move, and the connecting frame drives the base and the screw seat to move to a suitable position. Then, the screw rod is rotated, and the screw rod moves up and down in the screw seat, thereby adjusting the position of the contact seat, which supports the tooling.

[0010] As a further improvement of this utility model, a scale layer is provided on the upper surface of the horizontal plate of the connecting frame. After the vertical plate of the connecting frame abuts against the inner wall of the base, the starting point of the scale layer is set on the same plane as the outer wall of the base.

[0011] The above technical solution makes it easy to determine the position of the connecting bracket inside the base.

[0012] As a further improvement of this utility model, the angle adjustment mechanism includes:

[0013] Two adjusting rings are provided, each embedded and fixed in a circular groove on the connecting frame, and the adjusting rings are embedded in an annular groove on the connecting column.

[0015] The linkage gear consists of two gears, which are fitted and fixed one-to-one on the rotating rod, and the two linkage gears are meshed together.

[0016] An adjusting rod is screwed into the upper end of a connecting column via a bearing. The adjusting rod is connected to the top of one of the rotating rods via a worm gear pair. One end of the adjusting rod is connected to a drive rod via a bevel gear pair. The drive rod is screwed into the connecting column via a bearing, and the top of the drive rod passes through the top of the connecting column and protrudes on the upper side of the connecting column.

[0017] With the above technical solution, the drive rod is rotated, and the drive rod drives the adjusting rod to rotate through the bevel gear pair. The adjusting rod drives the rotating rod connected to it to rotate through the worm gear pair. The rotating rod rotates through the linkage gear on it and the linkage gear on another rotating rod, thereby causing the other rotating rod to rotate. At this time, the two rotating rods rotate in opposite directions. The rotating rod drives the adjusting ring to rotate through the adjusting gear on its respective rotating rod. The adjusting ring drives the corresponding connecting frame to rotate.

[0018] As a further improvement of this utility model, the upper and lower ends of the connecting column are fitted with and fixed with limit rings, and the limit rings respectively abut against the outer side wall of the adjacent connecting frame.

[0021] Two adjusting screws are symmetrically connected to the vertical plate of the connecting frame by threads. The two ends of the adjusting screws are respectively connected to the inner walls of the two sides of the base by bearings. The two adjusting screws are connected to each other by a synchronous pulley transmission assembly.

[0022] The drive shaft is screwed into the front side wall of the base via a bearing. The drive shaft is connected to one end of an adjusting screw located in the side wall of the base via a worm gear pair. The turning disc at the front end of the drive shaft is located in a circular groove on the front side wall of the base.

[0023] Two support guide rods are fixed symmetrically to one side wall of the connecting frame vertical plate. The support guide rods are movably inserted into the side wall of the base. A limit plate is fixed to the end of the support guide rod away from the connecting frame vertical plate. The limit plate is movably set in a cylindrical groove inside the base.

[0024] With the above technical solution, the drive shaft is rotated, and the drive shaft drives the adjacent adjusting screw to rotate through the worm gear pair. The adjusting screw drives another adjusting screw to rotate through the synchronous wheel transmission assembly, and the two adjusting screws drive the connecting frame to move.

[0025] As a further improvement of this utility model, a rotating rod is inserted inside the spiral rod. The protrusion on the outer ring wall of the rotating rod is movably inserted into the strip groove on the inner ring wall of the spiral rod. The bottom end of the rotating rod is connected to a rotating shaft through a worm gear pair. The rotating shaft is screwed onto the lower end of the spiral seat through a bearing. The turning disc at the front end of the rotating shaft is located in the circular groove on the front side of the outer ring wall of the spiral seat.

[0026] With the above technical solution, when adjusting the position of the contact seat, the rotating shaft is rotated, and the rotating shaft drives the rotating rod to rotate through the worm gear pair. The rotating rod drives the spiral rod to rotate through the protrusion on the outer ring wall. During the rotation of the spiral rod, the contact seat moves up and down.
