Description

Technical Field

[0001] The present application relates to the technical field of auxiliary hangers, and in particular to an auxiliary hanger for hoisting power equipment. Background Art

[0002] During power construction and equipment power connection, it is often necessary to lay circuits, so the cable drums need to be transported to the corresponding locations to complete the laying of power. The existing transportation of cable drums is generally achieved by trucks and cranes to transfer the cables.

[0003] The disclosure of "CN118811675A" discloses a cable drum hoist for cable laying, which connects the cable drum by a No. 1 clamping arm and a No. 2 clamping arm. During the lifting process, as the lifting weight increases, the force on the load-bearing shaft increases, and the stability between the No. 1 clamping arm and the No. 2 clamping arm increases. The stability during the lifting process is high and it is not easy to fall off. This is suitable for lifting flat cable drums, but existing cable drums are generally placed vertically during use and transportation. When the vertical cable drum needs to be transported, the steel rope is generally passed through the inner hole of the cable drum, and then the two ends of the steel rope are hooked on the cable drum to achieve lifting. However, this lifting method has poor stability during use. The lifted cable drum is prone to shaking when the crane moves, especially in windy weather. When lifting multiple cable drums, the steel rope needs to be frequently passed through and removed from the cable drum, and most cable drums are installed with multiple reinforcing ribs on both end faces, which affects the workers' ability to pass the cable through the cable drum, resulting in low lifting efficiency.

[0004] Therefore, the present invention proposes an auxiliary hanger for hoisting electric power equipment. Summary of the Invention

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] like Figures 1-12 As shown, an auxiliary hanger for hoisting power equipment proposed in one embodiment of the present application includes:

[0037] A connecting cover 1 is provided with a plurality of lifting rings, two movable frames 2 are symmetrically and slidably mounted on the connecting cover 1, and a driving assembly 3 for driving the movable frames 2 is installed on the connecting cover 1;

[0038] The expansion mechanism 4 includes two support parts 401 mounted on the movable frame 2. The support parts 401 are partially used to pass through the cable drum axis and are located inside. The support parts 401 are rotatably mounted at the position inside the cable drum. The support plates 402 are distributed in a circular array. Trigger members 403 are installed at opposite ends of the two support parts 401. The trigger members 403 act on the multiple support plates 402. When the two trigger members 403 conflict with each other, the free ends of the multiple support plates 402 rotate in a direction away from the support parts 401.

[0039] Among them, the support plate 402 is located in the support part 401 in normal state, and the connecting cover 1 is connected to the hook on the existing crane when in use. First, the lifting rope moves downward to approach the cable drum, and then the two moving frames 2 are respectively close to the two ends of the cable drum through the driving component 3, so that the two support parts 401 are respectively passed through the axial holes of the cable drum, so that the support part 401 is partially located in the cable drum. As the two moving frames 2 approach each other, the two trigger members 403 will come into contact with each other and form a conflict with the movement of the moving frame 2, so that under the action of the trigger member 403, multiple support plates 402 will rotate, thereby realizing multiple support plates The free end of 402 abuts against the inner wall of the cable reel, thereby achieving the function of quickly supporting the cable reel. During lifting, the cable reel is supported and fixed by multiple support plates 402, so the cable reel is not prone to shaking. During batch lifting, there is no need for staff to repeatedly pass the steel rope through the cable reel, which is more convenient to use and indirectly improves the lifting efficiency. In this embodiment, when the two trigger members 403 abut against each other, the two movable frames 2 at this time also move to fit with one end of the cable reel respectively, thereby further ensuring the stability of the cable reel, making it less likely for the cable reel to shake during lifting even in windy weather.

[0040] like Figure 1 、 Figure 10 and Figure 11As shown, in some embodiments, the trigger member 403 includes a sliding cylinder 4031 horizontally slidably mounted on the free end of the support portion 401, one side of the support plate 402 is open and hinged with a connecting rod 4032, the free end of the connecting rod 4032 is elastically hinged on the sliding cylinder 4031, specifically, a torsion spring is sleeved on the connecting rod 4032, one end of the torsion spring is connected to the sliding cylinder 4031, and the other end of the torsion spring is connected to the connecting rod 4032. Under the action of the torsion spring, the support plate 402 is always located in the support portion 401, that is, when the mobile racks 2 are mutually When they are close to each other, the two sliding cylinders 4031 are also approaching each other. When the two sliding cylinders 4031 contact and collide with each other, the sliding cylinder 4031 moves on the support part 401, thereby driving the multiple connecting rods 4032 to move. Because one end of the multiple connecting rods 4032 is respectively connected to the multiple support plates 402, the free ends of the multiple support plates 402 will move away from each other at this time, so that the free ends of the support plates 402 are supported on the inner wall of the cable drum, which is more convenient to use and does not require staff to additionally drive the rotation of the multiple support plates 402.

[0041] like Figure 1 、 Figure 10 and Figure 11 As shown, in some embodiments, the support portion 401 includes a connecting shaft 4011 horizontally slidably mounted on the mobile frame 2, and a plurality of mounting grooves 4012 are provided in a circular array on the connecting shaft 4011. In normal state, the support plate 402 is located in the mounting groove 4012, and one end of the support plate 402 close to the corresponding mobile frame 2 is hinged on the mounting groove 4012. A sliding hole 4013 is provided at one end of the connecting shaft 4011, and a sliding cylinder 4031 is slidably inserted into the sliding hole 4013. A driving member 5 is installed for driving the connecting shaft 4011 to move horizontally. It should be noted that the normal state here refers to when there is no lifting, multiple support plates 402 are located in the installation groove 4012, so as to ensure that when the connecting shaft 4011 passes through the shaft hole of the cable drum, multiple support plates 402 can also pass through smoothly. The horizontal movement of the connecting shaft 4011 under the action of the driving member 5 effectively increases the range of lifting. When facing different types of cable drums, it can also ensure that the two sliding cylinders 4031 are in contact and the support plates 402 are stretched open.

[0042] like Figure 6 and Figure 8As shown, in some embodiments, the mobile frame 2 is symmetrically provided with a first vertical slide groove 501 and a second horizontal slide groove 502. The first slide groove 501 is located above the second slide groove 502 and is inclined at the bottom end to provide a guide slide groove 506. A transition groove 503 is provided between the guide slide groove 506 and the proximal end of the second slide groove 502. The driving member 5 includes a plurality of articulated sleeve rods 504. The outer peripheral side of the articulated sleeve rod 504 is symmetrically provided with a column rod 508 for moving in the first slide groove 501 and the second slide groove 502. One end of the articulated sleeve rod 504 is configured with a connecting protrusion. 507, a connecting groove 505 is provided at one end of the articulated sleeve 504 away from the connecting protruding rod 507, and the articulated sleeve 504 is hinged in the connecting groove 505 of another articulated sleeve 504 through the connecting protruding rod 507, and the articulated sleeve 504 at the head is hinged on the connecting shaft 4011, and a driving member 6 is installed on the mobile frame 2, and the articulated sleeve 504 at the tail is connected to the driving member 6, and the articulated sleeve 504 at the tail is driven to move by the driving member 6. When multiple articulated sleeves 504 are horizontal, the ends of adjacent articulated sleeves 504 fit together, such as Figure 6 As described above, the multiple articulated sleeves 504 are distributed in an L shape, and the column 508 on the vertical articulated sleeve 504 is located in the first slide groove 501. The end faces of the adjacent horizontal articulated sleeves 504 are flush with each other under the limitation of the rotation angle and the action of gravity. Therefore, when the top vertical articulated sleeve 504 is driven by the driving member 6 to move, the multiple articulated sleeves 504 can be driven to move. When the top articulated sleeve 504 moves upward, the connecting shaft 4011 will move in the direction away from the cable drum, thereby controlling the connecting shaft 401 1 is located inside the cable drum. By moving multiple articulated sleeve rods 504, the space required for moving the connecting shaft 4011 can be effectively reduced. Of course, the connecting shaft 4011 can also be driven to move in other ways. For example, the connecting shaft 4011 can be extended, and a spring telescopic rod is installed on one side of the movable frame 2. A positioning hole for inserting the free end of the spring telescopic rod is horizontally opened on the connecting shaft 4011, so that after the connecting shaft 4011 is moved, the free end of the spring telescopic rod is inserted into the positioning hole to limit the connecting shaft 4011.

[0043] like Figure 5 、 Figure 9 and Figure 12As shown, in some embodiments, the driving member 6 includes a sliding frame 601 vertically slidably mounted on the moving frame 2, the sliding frame 601 is fixedly connected to the vertical and uppermost hinge sleeve rod 504, a limit rack 602 is vertically mounted on the moving frame 2, a positioning tooth plate 603 for engaging and limiting the position with the limit rack 602 is horizontally elastically slidably mounted on the sliding frame 601, a sliding block 604 is slidably mounted on the sliding frame 601, a hinge rod 605 is hinged between the sliding block 604 and the positioning tooth plate 603, specifically, a spring is installed between the sliding frame 601 and the positioning tooth plate 603, and in normal state, the positioning tooth plate 603 engages with the limit rack 602 under the action of the spring, and the sliding frame 601 is constructed with The handle, and the sliding block 604 is slidably mounted on the handle, which is more convenient to use. When the sliding block 604 is moved, the sliding block 604 will drive the hinged rod 605 hinged thereto to move. Because one end of the hinged rod 605 is hinged on the positioning tooth plate 603, the positioning tooth plate 603 will be disengaged from the limiting rack 602, and then contact the limit of the sliding frame 601. At this time, the moving sliding frame 601 will drive the vertical and uppermost hinged sleeve rod 504 to move, thereby adjusting the position of the connecting shaft 4011. The use of multiple hinged sleeve rods 504 can effectively reduce the horizontal space required for driving the connecting shaft 4011, and can also facilitate the movement of the connecting shaft 4011 when multiple cable reels are close to each other.

[0044] like Figure 5 、 Figure 9 and Figure 12As shown, in some embodiments, a connecting frame 7 is vertically slidably inserted on the mobile frame 2, and the connecting frame 7 slides horizontally in the connecting cover 1. The driving assembly 3 is used to drive the connecting frame 7 to move. A supporting spring 10 is installed between the connecting frame 7 and the sliding frame 601. In normal state, the supporting spring 10 is in an uncompressed state, and the mobile frame 2 has a vertical sliding spacing on the connecting frame 7. A connecting rope 11 is connected to the connecting frame 7, and the free end of the connecting rope 11 passes through a plurality of articulated sleeves 504 and is connected to the sliding cylinder 4031. In normal state, the connecting rope 11 is in a taut state under the action of gravity of the connecting frame 7. In this embodiment, in normal state, the supporting spring 10 is in a supporting sliding state. The movable frame 601 is in the state of the movable frame 601, so when the two sliding cylinders 4031 conflict with each other, the connecting rope 11 will become loose, and the movable frame 2 will not move. At this time, multiple support plates 402 conflict with the inner side of the cable drum. When the connecting cover 1 is lifted, the cable drum is lifted, and under the action of gravity, the movable frame 2 will move downward relative to the connecting frame 7. At this time, the support spring 10 will be compressed, so that the connecting rope 11 is tightened again. Because the connecting rope 11 is tightened under the action of gravity, the two connecting ropes 11 will give the two sliding cylinders 4031 a force to move away from each other, thereby increasing the force of the support plate 402 conflicting with the inner wall of the cable drum, further improving the supporting effect.

[0045] like Figure 1 As shown, in some embodiments, two sliding plates 12 are vertically slidably installed on the sliding frame 601, and a support roller 13 is installed between the two sliding plates 12. The connecting rope 11 has a reserved part, and the reserved part of the connecting rope 11 is wound around the support roller 13. An adjusting screw 15 is vertically and rotatably installed on the movable frame 2, and one of the sliding plates 12 is threadedly sleeved on the adjusting screw 15. In order to facilitate the movement of the sliding frame 601, that is, when it is necessary to adjust the horizontal position of the connecting shaft 4011, the adjusting screw 15 can be rotated to move the support roller 13, so that the connecting rope 11 becomes loose, which saves more effort when moving the sliding frame 601. After the sliding frame 601 moves, after ensuring that the two sliding cylinders 4031 can contact each other, the support plate 402 is stretched open. At this time, the adjusting screw 15 is rotated to make the support roller 13 contact with the connecting rope 11, so that the connecting rope 11 is tightened again.

[0046] like Figure 1 and Figure 6As shown, in some embodiments, a driving plate 14 is horizontally slidably installed on the movable frame 2, and a conical support sleeve 9 is installed at one end of the driving plate 14. The circumferential surface of the conical support sleeve 9 is used to contact the cable drum shaft hole, and a driving screw 8 is horizontally and rotatably installed on the movable frame 2. The driving plate 14 is threadedly sleeved on the driving screw 8, and the conical support sleeve 9 has a partition for the articulated sleeve 504 to pass through. When the two movable frames 2 approach each other so that the two sliding cylinders 4031 contact each other and the support plate 402 is opened, there is a certain gap between the movable frame 2 and the cable drum shaft hole. At this time, the driving screw 8 can be rotated so that the outer peripheral side of the conical support sleeve 9 contacts the cable drum shaft hole, thereby effectively improving the overall bearing capacity.

[0047] like Figure 3 As shown, in some embodiments, the driving assembly 3 includes two rotating rods 301 rotatably mounted on the connecting cover 1, and the two rotating rods 301 are each provided with a transmission wheel 302, and a transmission belt 303 is installed between the two transmission wheels 302. The two connecting frames 7 are respectively connected to the upper and lower horizontal sections of the transmission belt 303, and the connecting cover 1 is provided with a motor for driving one of the rotating rods 301 to rotate. That is to say, when one of the rotating rods 301 rotates, the transmission belt 303 will move at this time, and when the upper horizontal section of the transmission belt 303 moves to the right, the lower horizontal section of the transmission belt 303 will move to the left, thereby enabling the two connecting frames 7 to approach each other and the principle, which makes it more convenient to drive the connecting frame 7 to move.

[0048] like Figure 11 As shown, in some embodiments, the free end of the support plate 402 is in an outer arc shape, and the hinge between the connecting rod 4032 and the support plate 402 is close to the rotation axis of the support plate 402, so that when the sliding rod moves a small range, the connecting rod 4032 can drive the support plate 402 to rotate a large range, thereby making it more convenient to use. The outer arc shape of the free end of the support plate 402 can effectively increase the contact area between the support plate 402 and the inner wall of the cable reel.

[0049] Working principle: The two connecting frames 7 are respectively moved close to the two ends of the cable drum through the driving component 3, so that the support plate 402 passes through the shaft hole and is located in the cable drum. Then, the two connecting frames 7 are continued to be moved to make the two sliding cylinders 4031 conflict with each other, so that multiple support plates 402 are stretched open. Finally, the conical support sleeve 9 is moved into the cable shaft hole by rotating the adjusting screw 15, which limits the horizontal movement of the cable drum. When the same type of cable drums are subsequently lifted in batches, it is only necessary to control the movement of the two connecting frames 7 to position the cable drum. It is easy to use and indirectly improves work efficiency.

[0050] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
