[0031] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0032] The present application embodiment discloses a power construction pay-out frame. Figure 1 The construction pay-off frame includes a support frame body 1, a rotating shaft 2 and a deceleration assembly 3.

[0033] The support frame 1 includes two groups of brackets 11, which are arranged at intervals. The rotating shaft 2 is arranged between the two groups of brackets 11, and both ends of the rotating shaft 2 are connected to the brackets 11 on the corresponding side to carry the cable reel.

[0034] Reference Figure 1 and Figure 2 The rotating shaft 2 includes a bearing section 21 and two connecting sections 22. The two connecting sections 22 are respectively arranged at both ends of the bearing section 21, and the ends of the two connecting sections 22 away from the bearing section 21 are rotatably connected to the bracket 11 on the corresponding side. Both ends of the bearing section 21 are detachably connected to the connecting sections 22 on the corresponding side.

[0035] In this embodiment, the detachable connection between the load-bearing section 21 and the connecting section 22 is as follows: the connecting section 22 is threadedly connected with a sleeve 23 , and both ends of the load-bearing section 21 are plugged into and matched with the sleeve 23 on the corresponding side.

[0036] A hole for inserting the rotating shaft 2 is opened on the cable reel. In order to facilitate the staff to install the cable reel, the size of the rotating shaft 2 is generally smaller than the hole size of the cable reel. Therefore, after the cable reel is installed, the cable reel is prone to shaking. Based on this, the two connecting sections 22 are both slidingly sleeved with a fixing cone 221, and the tip of the fixing cone 221 is set toward the cable reel and can be plugged into the hole wall of the cable reel. The fixing cone 221 is threadedly connected with a fixing bolt 222.

[0037] After the staff puts the cable reel on the rotating shaft 2, they move the two fixing cones 221 to a position where they contact the peripheral wall of the hole of the cable reel to prevent the cable reel from moving. At this time, they rotate the fixing bolt 222 to make it contact with the rotating shaft 2, thereby achieving the installation of the cable reel.

[0038] In order to facilitate the staff to install the fixing cone 221, the size of the bearing section 21 in this embodiment is smaller than the size of the cable reel, so that after the staff installs the cable reel on the rotating shaft 2, the cable reel is padded by the sleeve 23, that is, the hole wall of the cable reel and the outer peripheral wall of the connecting section 22 are spaced apart, so that the staff can insert the fixing cone 221 into the hole of the cable reel.

[0039] Reference Figure 1 , Figure 3 and Figure 4 The deceleration assembly 3 is used to connect the rotating shaft 2 and the supporting frame 1, so that the cable drum is not prone to excessive rotation due to inertia. Two groups of deceleration assemblies 3 are provided, and one group of deceleration assemblies 3 is correspondingly connected to one connecting section 22.

[0040] The deceleration assembly 3 includes a connecting gear 31, a reduction gear 32, a reduction disc 33, a reduction spring 34 and a reduction block 35. The connecting gear 31 is coaxially fixedly connected to the corresponding connecting section 22. A support shaft 111 is fixedly connected to the bracket 11, and the support shaft 111 is located on the side of the bracket 11 away from the other bracket 11. The reduction gear 32 is rotatably connected to the support shaft 111 on the corresponding side of the bracket 11, and meshes with the connecting gear 31. The reduction disc 33 is rotatably connected to the support shaft 111 on the corresponding side of the bracket 11, and a reduction ring 321 is coaxially fixedly connected to the reduction gear 32, and the reduction ring 321 is sleeved on the outer side of the reduction disc 33. A plurality of reduction blocks 35 are provided. In this embodiment, three reduction blocks 35 are provided. The three reduction blocks 35 are evenly arranged along the circumference of the reduction disc 33, and the reduction blocks 35 are all slidably connected to the reduction ring 321 along the radial direction of the reduction disc 33. In this embodiment, the speed reduction plate 33 is provided with a slide groove 322 corresponding to the speed reduction block 35, and the speed reduction block 35 is located in the slide groove 322 and is slidably connected to the side wall of the slide groove 322. The speed reduction plate 33 is provided with a slot 331 for plugging and matching with the speed reduction block 35. The speed reduction ring 321 is provided with a driving member for driving the speed reduction block 35 to slide.

[0041] The driving member is a driving spring 4, which is located in the slide groove 322, and one end of the driving spring 4 is fixedly connected to the bottom of the slide groove 322, and the other end is fixedly connected to the speed reduction block 35. Under the elastic force of the driving spring 4, the speed reduction block 35 is partially inserted into the slot 331, and along the rotation direction of the cable reel when the cable reel is unwinding, the side surface of the part of the speed reduction block 35 that is engaged with the slot 331 is arranged as an inclined surface on the front side, so that when the cable reel is unwinding, the speed reduction disk 33 needs to be driven to rotate, and when the cable reel is winding up, there is no need to drive the speed reduction disk 33 to rotate.

[0042] The deceleration spring 34 is sleeved on the support shaft 111, and one end of the deceleration spring 34 is in contact with the deceleration disk 33, and the other end is connected to the support shaft 111. In this embodiment, in order to facilitate the regulation of the elastic force of the deceleration spring 34, a deceleration nut 112 is threadedly connected to the support shaft 111, and the end of the deceleration spring 34 away from the deceleration disk 33 is in contact with the deceleration nut 112.

[0043] During construction, the workers need to lay very long cables. Therefore, in order to reduce the work intensity of the workers, a regulating component 5 for regulating the engagement state of the speed reduction block 35 and the card slot 331 is provided on the pay-off frame. The regulating component 5 includes a regulating rope 51 and a regulating ring 52. There are multiple regulating ropes 51, and the regulating ropes 51 correspond to the speed reduction block 35 one by one. One end of the regulating rope 51 is fixedly connected to the speed reduction block 35, and the other end passes through the speed reduction ring 321 and is fixedly connected to the regulating ring 52. The regulating ring 52 is sleeved outside the speed reduction ring 321, and the inner circumferential wall of the regulating ring 52 is spaced from the outer circumferential wall of the speed reduction ring 321. The speed reduction ring 321 is provided with a locking member for locking the relative position of the regulating ring 52 and the speed reduction ring 321. The locking member is a locking nut 53, and the locking nut 53 is fixedly connected to the regulating ring 52 and is threadedly connected to the speed reduction ring 321.

[0044] The implementation principle of an electric power construction pay-off rack in an embodiment of the present application is as follows: when a worker needs to install a cable reel, first connect the load-bearing section 21 with a connecting section 22, then connect the cable reel with the load-bearing section 21, and then connect the load-bearing section 21 with another connecting section 22, and finally insert the fixing cone 221 into the hole of the cable reel, and rotate the fixing bolt 222 to lock the position of the fixing cone 221, thereby completing the installation of the cable reel.

[0045] When the staff needs to release the line, they only need to pull the end of the cable. When the length of the line to be released is longer, the locking nut 53 can be rotated first to allow the locking nut 53 to drive the regulating ring 52 to rotate, thereby pulling the regulating rope 51 to retract the deceleration block 35 into the slide groove 322, making it easier for the staff to pull the cable.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
