Description

Technical Field

[0001] The present invention relates to the technical field of nuclear fusion device component installation, in particular to a long-distance multi-angle manual installation tool. Background Art

[0002] Large components are usually composed of many small components. When assembling the small components, due to the small installation space, large components, and long installation distances, personnel cannot approach the component connections during the installation process and special installation tools must be used.

[0003] Traditional installation tools have a short installation distance and, due to the limited installation space, are unable to reach the joints between components through narrow installation gaps. Furthermore, many components are made of stainless steel (such as those used in nuclear equipment and food processing), while traditional installation tools are mostly made of carbon steel. When using carbon steel installation tools for installation, carbon steel and stainless steel come into contact, causing carburization of the stainless steel. This causes the stainless steel's corrosion resistance to decrease as the carbon content increases, leading to galvanic corrosion of the stainless steel.

[0004] In view of this, this application is hereby filed. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a long-distance, multi-angle manual installation tool. By improving the structure, the head of the installation tool is set to a rotatable structure, which can be turned within the range of 0 to 90°, so that it can flexibly pass through narrow installation gaps and can be suitable for complex installation conditions. At the same time, through the reasonable combination of materials of each component, the weight of the tool is greatly reduced, making the tool lightweight and suitable for installation environments with high cleanliness requirements and pollution-free.

[0006] The present invention is achieved through the following technical solutions:

[0007] A long-distance, multi-angle manual installation tool comprises a horizontally arranged installation connecting plate, a connecting block and a sleeve capable of driving the installation connecting plate to rotate around a horizontal axis;

[0008] The mounting connecting plate and the connecting block are mounted on the top end of the sleeve and can rotate relative to the sleeve around a horizontal axis;

[0009] A pull rod passing through the sleeve is provided in the sleeve, a slider is installed on the upper end of the pull rod, a waist-shaped hole is opened on the side wall of the slider, the lower end of the connecting block is connected to the waist-shaped hole of the slider through a pin shaft, and the end of the pin shaft can move in the waist-shaped hole of the slider;

[0010] The lower end of the sleeve is provided with a threaded sleeve connected to the lower end of the pull rod, and the upper end of the threaded sleeve is threadedly connected to the lower end of the sleeve;

[0011] By rotating the threaded sleeve, the pull rod can be driven to move linearly up and down in the sleeve.

[0012] The installation tool of the present invention has a head that is configured as a rotatable structure and can be turned within a range of 0 to 90 degrees, so that it can flexibly pass through narrow installation gaps and can be applied to complex installation conditions. Its specific working principle is as follows: when it is necessary to pass through a narrow gap between components to reach the inner installation position, the rotational motion of the threaded sleeve is converted into the linear motion of the pull rod by rotating the threaded sleeve, and the slider is pushed to move the end of the pin shaft in the slider's waist-shaped hole, thereby converting the slider's linear motion into the rotation of the connecting block, thereby realizing the rotation and steering of the installation connecting plate. After the installation connecting plate is rotated to a certain angle, the size of the front side passing through the narrow gap is reduced, so that the installation connecting plate can pass through the narrow installation gap to reach the inner installation position. The length and setting angle of the slider's waist-shaped hole determine the rotation angle of the installation connecting plate. By reasonably designing the length and setting angle of the waist-shaped hole, the steering activity of the installation connecting plate within the range of 0° to 90° can be accurately controlled.

[0013] Among them, the threaded sleeve is a trapezoidal threaded sleeve, and the trapezoidal thread can be self-locking (the thread lead angle is set to be smaller than the equivalent friction angle), so the installation tool can arbitrarily adjust the angle of the installation connecting plate within the range of 0 to 90° according to the needs of the installation angle, and the thread self-locking will not loosen, thereby ensuring stability during use.

[0014] Furthermore, an interface for connecting to the installation components is designed on the end face of the installation connecting plate, and two ribs are set on the lower surface of the installation connecting plate. Two mounting holes are provided on the ribs. Pins are set in the mounting holes for connecting to the connecting block and the sleeve. Shafts are fixed with retaining rings at both ends of the pins.

[0015] Furthermore, there are two connecting blocks, each of which is provided with three mounting holes, two of which are located at the upper end of the connecting block and are used to connect with the two mounting holes of the rib plate. One of the mounting holes is rotatably connected to a mounting hole on the rib plate of the mounting connecting plate through a rotating pin and the top of the sleeve, and the other mounting hole is connected to another mounting hole on the rib plate of the mounting connecting plate through a fixed pin; the last mounting hole is located at the lower end of the connecting block and is connected to the waist-shaped hole through a pin shaft, and shafts are fixed with retaining rings at both ends of the pin shaft; when the pull rod moves upward, the pin shaft moves in the waist-shaped hole of the slider, thereby driving the connecting block and the mounting connecting plate to rotate around the rotating pin at the same time.

[0016] Furthermore, the slider includes two parallel side plates and a bottom plate connecting the bottoms of the two side plates. Waist-shaped holes are provided on the walls of the two side plates. The lower ends of the two connecting blocks are connected to the two waist-shaped holes through the two ends of the pin shafts respectively. A threaded hole is provided on the bottom plate, and the threaded hole is threadedly connected to the threaded head at the front end of the pull rod; further, a set screw is provided at the threaded connection to prevent loosening.

[0017] Furthermore, the sleeve includes a square tube and a round tube connected in sequence, and the square steel and the round tube are welded together. The upper end of the square tube is in the shape of a fork, which is used to fix the connecting plate and the connecting block. The rear end outer wall of the round tube is provided with a trapezoidal thread, and the trapezoidal thread sleeve and the round tube are connected by the trapezoidal thread.

[0018] Furthermore, a deep groove ball bearing structure is disposed within the central inner hole at the lower end of the trapezoidal threaded sleeve, and the deep groove ball bearing is sleeved on the outer wall of the tie rod. The deep groove ball bearing and the inner wall of the trapezoidal threaded sleeve are movably connected. A shaft-use elastic ring is sleeved on the outer wall of the tie rod above the deep groove ball bearing. A fixing nut is mounted on the outer wall of the tie rod above the deep groove ball bearing, and an end cap is mounted outside the fixing nut. The end cap is fixed to the bottom end of the trapezoidal threaded sleeve. The outer ring of the deep groove ball bearing is secured by a shoulder in the central inner hole of the trapezoidal threaded sleeve and the end cap, while the inner ring of the deep groove ball bearing is secured to the tie rod by a shaft-use elastic ring and a fixing nut.

[0019] Furthermore, four threaded through holes evenly distributed on the circumference of the end cover are provided, and hexagon socket screws are placed in the threaded through holes to connect the end cover to the sleeve.

[0020] Furthermore, a silicone hose is provided on the outer layer of the sleeve. The length and size of the silicone hose are determined by the outer dimensions of the sleeve, which can ensure that the sleeve avoids scratching against the components when passing through the gaps between the components, and prevents debris generated by scratching from contaminating the installation environment.

[0021] Furthermore, the sleeve is made of aluminum alloy, and the mounting plate, fixing pin, connecting block, pin shaft, slider, set screw, pull rod, trapezoidal thread sleeve, end cover, fixing nut, hexagon socket screw, and rotating pin are all made of stainless steel SS304.

[0022] The sleeve of this invention is made of aluminum alloy, which is lightweight and easy to hold during installation. All other components are made of SS304 stainless steel, which prevents galvanic corrosion of the installation tool during use. By rationally combining the materials of various components, this invention significantly reduces the weight of the tool, making it lightweight and suitable for installation environments requiring high cleanliness and pollution-free operation.

[0023] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0024] 1. The present invention provides a long-distance, multi-angle manual installation tool. The head is configured as a rotatable structure. The trapezoidal thread transmission converts the rotary motion into the linear motion of the pull rod, thereby driving the installation connecting plate to rotate within a range of 0 to 90 degrees. This allows it to flexibly pass through narrow installation gaps and is suitable for complex installation conditions.

[0025] 2. The long-distance, multi-angle manual installation tool provided by the present invention is made of aluminum alloy, which is lightweight and easy to hold for installation activities. Other components are made of SS304 stainless steel, which can prevent galvanic corrosion of device components during use.

[0036] Example 1

[0037] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a long-distance multi-angle manual installation tool, comprising a horizontally arranged installation connecting plate 1, a connecting block 3 capable of driving the installation connecting plate 1 to rotate around a horizontal axis, and a sleeve;

[0038] The mounting connecting plate 1 and the connecting block 3 are mounted on the top of the sleeve and can rotate around a horizontal axis relative to the sleeve;

[0039] A pull rod 7 passing through the sleeve is provided in the sleeve, and a slider is installed on the upper end of the pull rod 7. A waist-shaped hole is opened on the side wall of the slider 5. The lower end of the connecting block 3 is connected to the waist-shaped hole of the slider 5 through a pin 4, and the end of the pin 4 can move in the waist-shaped hole of the slider 5.

[0040] The lower end of the sleeve is provided with a threaded sleeve 10 connected to the lower end of the pull rod 7, and the upper end of the threaded sleeve 10 is threadedly connected to the lower end of the sleeve;

[0041] By rotating the threaded sleeve 10 , the pull rod 7 can be driven to move linearly up and down in the sleeve.

[0042] The installation tool of the present invention has a rotatable head structure that can be turned within a range of 0 to 90 degrees, so that it can flexibly pass through narrow installation gaps and is suitable for complex installation conditions. Its specific working principle is as follows: when it is necessary to pass through the narrow gap of component 17 to reach the inner installation position, the rotational motion of the threaded sleeve 10 is converted into the linear motion of the pull rod by rotating the threaded sleeve, and the slider is pushed to move so that the end of the pin shaft 4 moves in the waist-shaped hole of the slider 5, thereby converting the linear motion of the slider into the rotation of the connecting block, thereby realizing the rotation and steering of the installation connecting plate. After the installation connecting plate is rotated to a certain angle, the size of the front side passing through the narrow gap is reduced, so that the installation connecting plate can pass through the narrow installation gap to reach the inner installation position. The length and setting angle of the waist-shaped hole of the slider 5 determine the rotation angle of the installation connecting plate 1. By reasonably designing the length and setting angle of the waist-shaped hole, the steering activity of the installation connecting plate within the range of 0° to 90° can be accurately controlled.

[0043] Among them, the threaded sleeve 10 is a trapezoidal threaded sleeve. The trapezoidal thread can self-lock and set the thread lead angle to be smaller than the equivalent friction angle. Therefore, the installation tool can arbitrarily adjust the angle of the installation connecting plate within the range of 0 to 90° according to the requirements of the installation angle, and the thread self-locking will not loosen, thereby ensuring stability during use.

[0044] Furthermore, an interface for connecting to the installation components is designed on the end face of the installation connecting plate, and two ribs are set on the lower surface of the installation connecting plate. Two mounting holes are provided on the ribs. Pins are set in the mounting holes for connecting to the connecting block and the sleeve. Shafts are fixed with retaining rings at both ends of the pins.

[0045] Furthermore, there are two connecting blocks 3, each of which is provided with three mounting holes, two of which are located at the upper end of the connecting block and are used to connect with the two mounting holes of the rib plate. One of the mounting holes is rotatably connected to a mounting hole on the rib plate of the mounting connecting plate through a rotating pin 16 and the top of the sleeve, and the other mounting hole is connected to another mounting hole on the rib plate of the mounting connecting plate through a fixing pin 2; the last mounting hole is located at the lower end of the connecting block and is connected to the waist-shaped hole through a pin shaft, and shaft retaining rings are set at both ends of the pin shaft for fixing; when the pull rod 7 moves upward, the pin shaft 4 moves in the waist-shaped hole of the slider 5, thereby driving the connecting block 3 and the mounting connecting plate 1 to rotate around the rotating pin 16 at the same time.

[0046] Furthermore, the slider 5 includes two parallel side plates and a bottom plate connecting the bottoms of the two side plates. Waist-shaped holes are provided on the walls of the two side plates. The lower ends of the two connecting blocks 3 are connected to the two waist-shaped holes through the two ends of the pin shaft 4 respectively. A threaded hole is provided on the bottom plate, and the threaded hole is threadedly connected to the threaded head at the front end of the pull rod; further, a set screw 6 is provided at the threaded connection to prevent loosening.

[0047] Furthermore, the sleeve includes a square tube 8 and a round tube 9 connected in sequence, which are welded together. The upper end of the square tube 8 is in the shape of a fork, which is used to fix the connecting plate 1 and the connecting block 3. The outer wall of the rear end of the round tube 9 is provided with a trapezoidal thread, and the trapezoidal thread sleeve and the round tube 9 are connected by a trapezoidal thread.

[0048] Furthermore, a deep groove ball bearing 12 is disposed within the central inner hole at the lower end of the trapezoidal threaded sleeve 10. The deep groove ball bearing 12 is sleeved on the outer wall of the tie rod 7, and is movably connected to the inner wall of the trapezoidal threaded sleeve 10. A shaft circlip 11 is sleeved on the outer wall of the tie rod 7 above the deep groove ball bearing 12. A fixing nut 14 is mounted on the outer wall of the tie rod 7 above the deep groove ball bearing 12. An end cap 13 is mounted outside the fixing nut 14, and the end cap 13 is fixed to the bottom end of the trapezoidal threaded sleeve 10. The outer ring of the deep groove ball bearing 12 is secured by the shoulder and end cap of the central inner hole of the trapezoidal threaded sleeve 10, while the inner ring of the deep groove ball bearing 12 is secured to the tie rod via a shaft circlip and fixing nut.

[0049] Furthermore, four threaded through holes evenly distributed on the circumference of the end cover are provided, and hexagon socket screws 15 are placed in the threaded through holes to connect the end cover to the sleeve.

[0050] Furthermore, a silicone hose is provided on the outer layer of the sleeve, and the length and size of the silicone hose are determined by the outer dimensions of the sleeve, which can ensure that the sleeve avoids scratching with the component 17 when passing through the gap of the component 17, thereby preventing the debris generated by the scratching from contaminating the installation environment.

[0051] Furthermore, the material of the sleeve is aluminum alloy, and the material of the mounting connecting plate 1, fixing pin 2, connecting block 3, pin shaft 4, slider 5, set screw 6, pull rod 7, trapezoidal thread sleeve 10, end cover 13, fixing nut 14, hexagon socket screw 15, and rotating pin 16 are all stainless steel SS304.

[0052] The sleeve of the present invention is made of aluminum alloy, and the length of the pull rod and sleeve can be set to 1 to 1.5 meters, solving the problem of the short installation distance of existing tools. The lightweight aluminum alloy significantly reduces the weight of the connection tool and makes it easy to hold during installation. All other components are made of SS304 stainless steel, which can prevent galvanic corrosion of the installation tool during use. By rationally combining the materials of various components, the present invention significantly reduces the weight of the tool, making it lightweight and suitable for installation environments with high cleanliness requirements and pollution-free conditions.
