Description

Technical Field

[0001] This utility model relates to a jacking device for moving equipment during installation and maintenance, belonging to the technical field of mechanical equipment loading and unloading tools. Background Technology

[0002] In special locations such as the field, tunnels, alleyways, and narrow construction sites, environmental factors often prevent the use of hoisting machinery for equipment installation and disassembly. In these areas, when mechanical equipment such as motors and couplers cannot be moved using cranes during installation, disassembly, or maintenance, rollers are often used to support the equipment from below, requiring manual pushing and pulling. This is time-consuming, labor-intensive, and carries a high risk of equipment damage. Furthermore, manually pushing and pulling equipment with rollers at higher installation locations poses significant safety risks. Especially after motor equipment is installed, adjustments to the connection distance and coupling alignment are necessary. Inaccurate equipment positioning can affect installation quality, reduce lifespan, and increase equipment costs. Therefore, designing a tool for moving equipment requiring installation and maintenance in locations where hoisting machinery is not feasible is essential. Utility Model Content

[0021] This utility model consists of a support rail 1, a base 2, a push screw 3, a positioning hook 4, and a hook positioning column 5.

[0022] Figure 1 , 2 As shown in Figure 3, the support rail 1 is a hollow rail with a U-shaped cross-section. The upper part of each of the two U-shaped sidewalls 6 of the support rail 1 has an inwardly protruding top plate 7. Multiple positioning grooves 8 with openings at their lower ends are evenly distributed along the length of the two top plates 7. The base 2 and the device 13 are placed on the top surface of the U-shaped sidewalls 6 on both sides of the support rail 1, and can slide along the top surface of the U-shaped sidewalls 6 on both sides of the support rail 1. The multiple positioning grooves 8 of the two top plates 7 are used to lock the hook positioning post 5 at the front end of the positioning hook 4, so that the base 2 above the positioning hook 4 can be positioned on the support rail 1 and cannot move.

[0023] Figure 1 , 3 As shown, the positioning groove 8 of the top plate 7 of the two U-shaped sidewalls 6 supporting the track 1 is semi-circular, with a horizontal surface at the top of the semi-circle. The width of the opening at the lower end of the positioning groove 8 is smaller than the diameter of the positioning groove 8, which facilitates the positioning hook positioning post 5 at the front end of the positioning hook 4 to be embedded into the positioning groove 8 from the bottom up.

[0024] Figure 1 , 6 The display shows that the base 2 is a cuboid, placed on the top surface of the support rail 1. The length of the base 2 is perpendicular to the length of the support rail 1, and the length of the base 2 matches the width of the support rail 1. The lower bottom front end of the base 2 has an inclined surface 9, which slides into contact with the top surface of the U-shaped sidewall 6 of the support rail 1. When the base 2 needs to slide along the support rail 1, it must be tilted so that the grab hook positioning post 5 connected below the base 2 disengages downward from the positioning groove 8 of the top plate 7. At this time, the inclined surface 9 at the front end of the base 2 contacts the top surface of the support rail 1, achieving a sliding engagement.

[0025] Figure 1 , 4Figure 5 shows that the base 2 has a lead screw hole 10, which is along the length of the support rail 1. The push screw 3 is embedded in the lead screw hole 10 of the base 1, and the push screw 3 is threadedly connected to the lead screw hole 10 of the base 2. A fastening nut 11 is fitted at the rear of the push screw 3, and the fastening nut 11 is threadedly connected to the push screw 3. The fastening nut 11 is tightly connected to the rear end of the lead screw hole 10 of the base 2. The rear end of the push screw 3 has a hexagonal nut 12. By rotating the hexagonal nut 12 at the rear end of the push screw 3, the push screw 3 can rotate forward along the lead screw hole 10. Tightening the fastening nut 11 can fix the push screw 3 to the base 2.

[0026] Figure 1 , 4 As shown in Figure 5, a clamping block 13 is connected to the front end of the push screw 3. The clamping block 13 is a disc, and the front end face of the push screw 3 has a circular groove in which a bearing is embedded. The rear end face of the clamping block 13 has a rotating rod, which is perpendicular to the rear end face of the clamping block 13. The diameter of the rotating rod matches the inner diameter of the bearing in the circular groove, and the rotating rod is inserted into the inner hole of the bearing in the circular groove. A wear-resistant rubber pad is attached to the front end face of the clamping block 13, and the rubber pad is opposite to the clamping device 14. When the push screw 3 rotates, the clamping block 13 and the bearing at the front end of the clamping screw 3 rotate relative to each other, while remaining relatively stationary with respect to the surface of the device 14, thus preventing damage to the surface of the device 14. The rubber pad further protects the surface of the device 14.

[0027] Figure 1 , 4 As shown in Figure 5, the positioning hook 4 is an L-shaped plate. The width of the positioning hook 4 matches the distance between the top plates 7 at the upper ends of the two U-shaped sidewalls 6 of the support rail 1. The upper end of the straight plate of the L-shaped plate of the positioning hook 4 is fixedly connected to the lower bottom surface of the base 2. The plate body of the positioning hook 4 is located in the U-shaped cavity of the support rail 1. The upper surface of the horizontal plate of the L-shaped plate of the positioning hook 4 is located below the lower bottom surface of the top plate 7 of the U-shaped sidewall 6 of the support rail 1. There is a gap between the upper surface of the horizontal plate and the lower bottom surface of the top plate 7 of the U-shaped sidewall 6.

[0028] Figure 1 , 4As shown in Figure 5, the grab hook positioning post 5 is cylindrical. The length of the grab hook positioning post 5 matches the distance between the inner walls of the two U-shaped side walls 6 of the support rail 1. The grab hook positioning post 5 is fixedly connected to the front end of the horizontal plate of the L-shaped plate of the positioning grab hook 4. The length direction of the grab hook positioning post 5 is perpendicular to the length direction of the support rail 1. The upper part of the cylindrical shape of the grab hook positioning post 5 matches the positioning groove 8. The two ends of the upper part of the cylindrical part of the grab hook positioning post 5 are respectively embedded in the positioning groove 8 of the top plate 7 of the support rail 1. The upper part of the cylindrical part of the grab hook positioning post 5 and the positioning groove 8 are tightly fitted. When the grab hook positioning post 5 is engaged in the positioning groove 8, it prevents the machine base 2 from moving back and forth and keeps it in the position on the support rail 1, allowing the push screw 3 to push the equipment 14 forward.

[0029] The usage process of this utility model is as follows:

[0030] When the mobile device 14 is needed, the device 14 is first placed on the top surface of the support rail 1, and then the base 2 is placed on the top surface of one end of the support rail 1. The positioning hook 4 is located in the gap between the two top plates 7 at the upper end of the support rail 1, and the hook positioning post 5 is outside the opening of the support rail 1.

[0031] When the base 2 is tilted forward, the inclined surface 9 at the lower front end of the base 2 contacts the top surface of the support rail 1. After the base 2 is tilted, the hook positioning post 5 at the front end of the positioning hook 4 can rotate downward to the bottom of the two top plates 7 of the support rail 1. It can enter the cavity between the U-shaped side walls 6 below the two top plates 7 of the support rail 1 from the opening at one end of the support rail 1.

[0032] Push the tilted base 2 forward and slide it. The base 2 drives the positioning hook 4 and the hook positioning post 5 to move forward together. When the base 2 moves to the front of the equipment 14, stop sliding and restore the base 2 to the vertical position. At this time, the two ends of the hook positioning post 5 are pressed against the lower surface of the two top plates 7. Then move the base 2 so that the hook positioning post 5 moves into the positioning groove 8 at the bottom of the nearest top plate 7 and is locked in place with the positioning groove 8 to position the base 2.

[0033] With the front of the clamping block 13 at the front end of the push screw 3 facing the device 14, rotate the hexagonal nut 12 at the rear end of the push screw 3, and the push screw 3 will rotate forward along the screw hole 10. The clamping block 13 at the front end of the push screw 3 will contact the device 14, and push the device 14 forward.

[0034] After the push screw 3 is rotated to its maximum position, if the equipment 14 is not yet in place, the push screw 3 can be rotated in the opposite direction to move it backward. The push screw 3 will retract to the last position of the base 2. Then the base 2 will be tilted so that the hook positioning post 5 under the base 2 will rotate downward and disengage from the positioning groove 8 of the top plate 7, pushing the base 2 forward and closer to the equipment 14. Then the vertical position of the base 2 will be restored so that the hook positioning post 5 will be re-embedded into another positioning groove 8, thus positioning the frame 2.

[0035] The action of rotating the push screw 3 is repeated, and the push screw 3 continues to push the device 14 forward.

[0036] Repeat the above process until the base 2 and the push screw 3 of the equipment 14 reach the installation or maintenance position for installation or maintenance.
