Description

A disassembly and handling device for threaded holes without lifting points Technical Field

[0001] This invention relates to the field of mechanical equipment parts handling and disassembly, and in particular to a disassembly and handling device for parts with threaded holes but no lifting points. Background Technology

[0002] Heavy machinery is usually equipped with lifting points. On large machinery that cannot be moved by manpower, the presence of lifting points allows workers to use cranes to lift the machinery and move it. However, after large machinery is disassembled, there are usually no lifting points on other parts except for the outer shell. When workers move such parts, they need to use pulleys or slides to move the parts up for transport. However, since there are no lifting points, it is difficult to move the parts to pulleys or slides.

[0003] Existing methods for handling such mechanical parts include screwing lifting points into the bolt holes on the parts and then mechanically transporting them. However, in many cases, the size of the bolt holes cannot match the type of bolt lifting points, rendering the bolt lifting points unusable. If tools are inserted into the bolt holes for manual transport, there is a risk that the mechanical parts may fall if the operator loosens their grip on the fixing point. Summary of the Invention

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one 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 is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Referring to Figures 1-8, the first embodiment of the present invention provides a disassembly and handling device for threaded holes without lifting points. Specifically, it includes a main frame mechanism 100, which includes a handle assembly 101 and a platform assembly 102 disposed below the handle assembly 101; and a clamping and locking mechanism 200, which includes a clamping assembly 201 disposed above the platform assembly 102 and a locking assembly 202 disposed below the clamping assembly 201.

[0034] Furthermore, the grip assembly 101 includes a grip bar 101a, a first fixing rod 101b fixed to the lower part of the grip bar 101a, and a second fixing rod 101c fixed to the lower part of the first fixing rod 101b; the platform assembly 102 includes a platform plate 102a fixed to the lower part of the second fixing rod 101c, an extension rod 102b fixed to the upper part of the platform plate 102a, and a first sliding column 102c fixed to the side wall of the extension rod 102b.

[0035] Furthermore, the gripping rod 101a has a gripping plate cavity W-1, the first fixing rod 101b has a gripping plate groove W-2 communicating with the gripping plate cavity W-1, and a gripping rod groove W-3 communicating with the lower part of the gripping plate groove W-2; the platform plate 102a has an ascending hole W-4 in the middle.

[0036] Preferably, the clamping assembly 201 includes a clamping plate 201a slidably disposed in the clamping plate cavity W-1, a first clamping rod 201b fixed to the lower part of the clamping plate 201a and slidably disposed in the lower part of the clamping plate groove W-2, and a second clamping rod 201c fixed to the lower part of the first clamping rod 201b and slidably disposed in the clamping rod groove W-3; the clamping assembly 201 also includes a rotating rod 201d symmetrically hinged to the bottom of the second clamping rod 201c, and clamping plates 201e symmetrically disposed on both sides of the second clamping rod 201c; the locking assembly 202 includes a pull rod 202a fixed to the bottom of the clamping plate 201e, a first ratchet plate 202b fixed to the bottom end of the pull rod 202a, and a sliding member 202c disposed below the clamping plate 201e; fine serrations are formed on the side walls of the two clamping plates 201e that are far apart from each other.

[0037] In this embodiment, the operator, through the cooperation of the main frame mechanism 100 and the clamping component 201, can fix the clamping component 201 to the wall of the threaded hole by compression after it is inserted into the threaded hole. After the clamping component 201 is fixed, the locking component 202 can automatically lock the relative position between the clamping component 201 and the wall of the threaded hole. The locking component 202 can also provide a certain amount of space for the operator to loosen after gripping the clamping component 201, preventing the operator from accidentally unlocking the locking component 202, thus making the relative fixation between the clamping component 201 and the wall of the threaded hole more secure.

[0038] Example 2

[0039] Referring to Figures 1 to 11, this is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, a first spring 201a-1 is provided between the gripping plate 201a and the gripping plate cavity W-1; a first drive groove W-5 and a second drive groove W-6 are provided on the clamping plate 201e; a second sliding column 201d-1 is fixed at one end of the rotating rod 201d, and the second sliding column 201d-1 is slidably disposed in the first drive groove W-5; the first sliding column 102c is slidably disposed in the second drive groove W-6.

[0041] It should be noted that after the operator grips the lever 101a and picks up the gripping plate 201a, the gripping plate 201a will overcome the elastic force of the first spring 201a-1 and be pressed into the gripping plate cavity W-1. This will cause the second gripping lever 201c to slide vertically upward at the hinge with the rotating lever 201d. This will cause the second sliding column 201d-1 to slide from the bottom end of the first drive groove W-5 to the top end of the first drive groove W-5, and then the angle between the two rotating levers 201d will increase. The increased angle between the two rotating levers 201d will cause the second sliding column 201d-1 to push the two clamping plates 201e away from each other and clamp onto the threads of the bolt holes on the parts to be moved.

[0042] Furthermore, the clamping plate 201e is also provided with a first clamping groove W-7 connected to the bottom side wall of the first driving groove W-5, and a second clamping groove W-8 connected to one end of the first clamping groove W-7. The bottom end of the second clamping groove W-8 penetrates the bottom of the clamping plate 201e. A first clamping block 201e-1 is slidably disposed in the first clamping groove W-7. The first clamping block 201e-1 is provided with a pulling force toward the bottom end of the first driving groove W-5 by a second spring 201e-2. A second clamping block 201e-3 is slidably disposed in the second clamping groove W-8. The second clamping block 201e-3 is provided with an oblique insertion hole K-1 opposite to the first clamping groove W-7.

[0043] It should be noted that after the second sliding column 201d-1 slides from the bottom end of the first drive groove W-5 to the top end of the first drive groove W-5, the first pressing block 201e-1 is no longer squeezed by the second sliding column 201d-1, and the end of the first pressing block 201e-1 will slide into the first drive groove W-5 under the pulling force of the second spring 201e-2; and after the oblique insertion hole K-1 on the second pressing block 201e-3 is no longer lifted by the first pressing block 201e-1, the second pressing block 201e-3 will slide downward under its own gravity.

[0044] Furthermore, the slide 202c includes a slide tube 202c-1, a fixing beam 202c-2 fixed above the slide tube 202c-1, and a third spring 202c-3 fixed below the fixing beam 202c-2; the slide tube 202c-1 has a compression hole K-2 at its upper part, and the first ratchet plate 202b is slidably disposed in the slide tube 202c-1; the top of the first ratchet plate 202b has ratchet teeth.

[0045] Preferably, the locking assembly 202 further includes a second ratchet plate 202d slidably disposed below the fixed beam 202c-2, and one end of the third spring 202c-3 is fixed to the upper part of the second ratchet plate 202d; the upper part of the second ratchet plate 202d is also provided with a compression groove K-3, and the bottom of the second pressure block 201e-3 is slidably disposed in the compression groove K-3; the second ratchet plate 202d is slidably disposed directly above the compression hole K-2, and the pull rod 202a does not fit against the side wall of the rising hole W-4; the bottom of the second ratchet plate 202d is provided with ratchet teeth.

[0046] It should be noted that when the second ratchet plate 202d presses on the first ratchet plate 202b, and the ratchet teeth on the second ratchet plate 202d and the ratchet teeth on the first ratchet plate 202b mesh, the two first ratchet plates 202b can only separate from each other. When the two first ratchet plates 202b are subjected to a force that brings them closer together, they will be blocked by the ratchet teeth on the second ratchet plate 202d.

[0047] In this embodiment, when the operator needs to move a part, the clamping plate 201e needs to be inserted into the bolt hole on the part to be moved. After that, the operator only needs to hold the gripping rod 101a and squeeze the gripping plate 201a with their fingers and lift it upward. During this process, the gripping plate 201a will overcome the elastic force of the first spring 201a-1 and be pressed into the gripping plate cavity W-1. This will cause the second gripping rod 201c to slide vertically upward at the hinge point with the rotating rod 201d, so that the second sliding column 201d-1 first moves from... After the bottom end of the first drive groove W-5 slides to the top end of the first drive groove W-5, the angle between the two rotating rods 201d increases. The increased angle between the two rotating rods 201d causes the second sliding column 201d-1 to push the two clamping plates 201e away from each other and clamp onto the threads of the bolt holes on the parts to be moved. The first sliding column 102c slides in the second drive groove W-6, causing the clamping plates 201e to slide obliquely upward along the direction of the second drive groove W-6 as they move away from each other.

[0048] It should be noted that when the two clamping plates 201e move away from each other at an angle, since the pull rods 202a are fixed at the bottom of the clamping plate 201e, the two pull rods 202a will be pulled out of the slide tube 202c-1 and rise together with the clamping plate 201e. During this process, the locking assembly 202 as a whole will be pulled up and slide above the rising hole W-4 before the pull rods 202a touch the side wall of the rising hole W-4. When the two pull rods 202a move away from each other, the second ratchet plate 202d presses on the first ratchet plate 202b. After the ratchet teeth on the second ratchet plate 202d and the ratchet teeth on the first ratchet plate 202b are engaged, the two first ratchet plates 202b can only separate from each other. When the two first ratchet plates 202b are subjected to a force that brings them closer together, they will be blocked by the ratchet teeth on the second ratchet plate 202d. Therefore, the distance between the two pull rods 202a is fixed and they cannot get closer. The clamping plate 201e can be firmly clamped onto the threads of the bolt holes on the parts being transported.

[0049] It should also be noted that when the operator reduces the force applied to the gripper 201a, causing it to slide down, the displacement of the gripper 201a will be transmitted to the rotating rod 201d through the hinge between the second gripper 201c and the rotating rod 201d. This causes the second sliding column 201d-1 to slide from the top of the first drive groove W-5 to the bottom of the first drive groove W-5. However, a small displacement will not cause the second sliding column 201d-1 to slide to the bottom of the first drive groove W-5. When the operator needs to release the clamping plate 201e from the threads of the bolt holes on the part being transported, the operator only needs to stop gripping it. The gripper 201a slides down under the elastic force of the first spring 201a-1, causing the second slide column 201d-1 to slide to the bottom of the first drive groove W-5. After that, the second slide column 201d-1 will squeeze the first pressure block 201e-1, causing the second pressure block 201e-3 to be squeezed up. The rising second pressure block 201e-3 will drive the second ratchet plate 202d to disengage from the first ratchet plate 202b, allowing the first ratchet plate 202b to retract. The locking of the clamping plate 201e is also released, and the entire clamping assembly 201 can be pulled out of the bolt hole on the part being transported.

[0050] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
