Description

Technical Field

[0001] This invention relates to the field of elbow-type head extraction technology, and in particular to an elbow-type head extraction device. Background Technology

[0002] After a period of operation, the pluggable cable elbow joints of box-type equipment generate heat due to the current passing through them. Thermal expansion and contraction cause the silicone grease to create a strong gripping force between the elbow joint and the equipment sleeve, making disassembly difficult when it is necessary to pull it out.

[0003] Traditional methods of pulling out cables typically require two people to work together and shake the cable up, down, left, and right. During the disassembly process, uneven force or excessive force can cause rebound, which can easily damage the outer silicone grease protective layer, causing the silicone rubber to loosen and become fatigued, resulting in surface cracks and even damage to the sleeve stress. This leads to a decrease in the electrical performance of the cable terminal and affects the safe operation of the equipment. Therefore, it is necessary to solve the above problems. Summary of the Invention

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] 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.

[0028] 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 throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1

[0030] Reference Figure 1 This is the first embodiment of the present invention, which provides an elbow-type head pull-out device capable of quickly pulling out the elbow-type head. It includes a control component 100, comprising a hydraulic assembly 101, a support assembly 102 mounted on the hydraulic assembly 101, a sliding assembly 103 mounted on the support assembly 102, and a pulling assembly 104 mounted on the hydraulic assembly 101; and...

[0031] The clamping component 200 is used to clamp the elbow head to prevent wear. It is installed on the control component 100 and includes a clamping component 201 installed on the pulling component 104 and a buckle component 202 installed on the clamping component 201.

[0032] In summary, by using the control component 100 and the clamp component 200 together, the elbow head can be quickly pulled out easily and effortlessly, solving the problem that traditional pulling methods are laborious and easily cause wear to the silicone protective layer on the outer surface of the elbow head.

[0033] Example 2

[0034] Reference Figures 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that it further includes a control component 100. In the previous embodiment, the elbow-type head pull-out device includes a control component 100, which includes a hydraulic assembly 101, a support assembly 102 mounted on the hydraulic assembly 101, a sliding assembly 103 mounted on the support assembly 102, and a pulling assembly 104 mounted on the hydraulic assembly 101.

[0035] Furthermore, the hydraulic assembly 101 includes a hydraulic pump 101a, a handle 101b mounted on the hydraulic pump 101a, and a push rod 101c telescopically connected to the hydraulic pump 101a. When the handle 101b is pressed back and forth, the push rod 101c will be pushed forward.

[0036] Furthermore, the support assembly 102 includes a top plate 102a fixedly connected to the end of the top rod 101c. The top plate 102a is in the shape of a "U". A through opening 102b is opened on the top plate 102a. Three sets of connecting rods 102c are fixedly connected to the top plate 102a. Horseshoe rings 102d are fixedly connected to the connecting rods 102c.

[0037] Furthermore, the sliding assembly 103 includes a sliding sleeve 103a slidably connected to the connecting rod 102c, and a fixing bracket 103b fixedly connected to the sliding sleeve 103a.

[0038] Furthermore, the pulling assembly 104 includes a fixed ring 104a fixedly connected to the hydraulic pump 101a, two sets of pull rods 104b fixedly connected to the fixed ring 104a, and a blocking member 104c disposed on the pull rods 104b. The pull rods 104b pass through the through-hole 102b and are slidably connected thereto. The pull rods 104b are fixedly connected to the fixing frame 103b. The fixing frame 103b can limit the specific relationship between the two sets of pull rods 104b, preventing them from moving away from each other when the pull rods 104b are subjected to a large pulling force. When the handle 101b is pressed back and forth, the push rod 101c extends and drives the fixed ring 104a backward through the reaction force, thereby driving the pull rods 104b to move in the opposite direction away from the horseshoe ring 102d.

[0039] Furthermore, the blocking member 104c includes two sets of mounting grooves 104c-1 formed at the end of the pull rod 104b, a stop rod 104c-2 rotatably connected to the mounting groove 104c-1, a transmission block 104c-3 fixedly connected to the stop rod 104c-2, an inclined surface 104c-4 formed on the transmission block 104c-3, a sliding groove 104c-5 formed on the pull rod 104b, a push block 104c-6 slidably connected to the sliding groove 104c-5, and a component fixedly mounted on the push block.

[0040] The elastic element 104c-7 between 104c-6 and the slide groove 104c-5, when not disturbed by external forces, pushes the push block 104c-6 with the thrust of the elastic element 104c-7, which will push the stop rod 104c-2 into an open state through the transmission block 104c-3. When the stop rod 104c-2 is tightened in the mounting groove 104c-1, the curvature of the outer surface of the stop rod 104c-2 will be consistent with the curvature of the outer side of the pull rod 104b.

[0041] When in use, when the operating handle 101b is pressed back and forth, the push rod 101c will be extended by hydraulic pressure. Since the push rod 101c is fixedly connected to the top plate 102a and the fixing ring 104a is fixedly connected to the hydraulic pump 101a, when the handle 101b is pressed back and forth, the extension of the push rod 101c will drive the fixing ring 104a to retract through the reaction force, thereby driving the pull rod 104b to move in the opposite direction away from the horseshoe ring 102d.

[0042] In summary, by using the hydraulic assembly 101, the support assembly 102, the sliding assembly 103, and the pulling assembly 104 together, the effect of pressing the handle 101b can be achieved to drive the pull rod 104b to move away from the horseshoe ring 102d.

[0043] Example 3

[0044] Reference Figures 5-6This is the third embodiment of the present invention, which differs from the previous two embodiments in that it includes a clamping component 200, which is used to clamp the elbow head to prevent wear. It is installed on the control component 100 and includes a clamping component 201 installed on the pulling component 104 and a buckle component 202 installed on the clamping component 201.

[0045] Furthermore, the clamping assembly 201 includes a right-angle clamp 201a disposed at the end of the pull rod 104b, two sets of fixing tubes 201b fixedly connected to the right-angle clamp 201a, a rotating tube 201c rotatably connected to the outside of the fixing tubes 201b, and a locking ring 201d fixedly connected to the rotating tube 201c. That is, the locking ring 201d is rotatably connected to the fixing tubes 201b through the rotating ring. Since the fixing tubes 201b are hollow tubes, the pull rod 104b can pass through the center of the fixing tubes 201b.

[0046] Furthermore, the latch assembly 202 includes a latch seat 202a fixedly connected to one set of locking rings 201d, a mounting seat 202b fixedly connected to the other set of locking rings 201d, a lever 202c rotatably connected to the mounting seat 202b, and a ring buckle 202d rotatably connected to the lever 202c. When the two sets of locking rings 201d are closed, the lever 202c can be operated to engage the ring buckle 202d on the lever 202c with the latch seat 202a. Then, the lever 202c is pressed until it is flush with the mounting seat 202b to complete the fixation between the two sets of locking rings 201d.

[0047] When using the elbow head, if it is necessary to pull it out, first place the right-angle clamp 201a inside the elbow head, then operate the two sets of locking rings 201d to surround the upper half of the elbow head and fasten the buckle to the buckle seat 202a. Then, place the horseshoe ring 102d above the elbow head, so that the elbow head is in the middle of the horseshoe ring 102d. Then, operate the pull rod 104b to move towards the fixing tube 201b, so that the pull rod 104b passes through the fixing tube 201b. When the pull rod 104b passes through the fixing tube 201b, the stop rod 104c-2 will automatically retract into the mounting groove 104c-1. Inside, after passing through the fixed tube 201b, the transmission block 104c-3 on the stop lever 104c-2 is pushed by the push block 104c-6, causing the stop lever 104c-2 to open. At this time, the handle 101b can be pressed. As the push rod 101c slowly extends, the reaction force of the push rod 101c will drive the fixed ring 104a to move backward, thereby driving the pull rod 104b to move away from the horseshoe ring 102d. Under the action of the stop lever 104c-2, the right angle clamp 201a will move simultaneously with the pull rod 104b, thus easily pulling out the horseshoe ring 102d.

[0048] In summary, by using the clamping component 201 and the latching component 202 together, the surface of the elbow head can be protected during the removal of the elbow head.
