DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] The present application provides a cable retracting and releasing structure to solve the problems existing in the existing manual cable winding.

[0046] In order to facilitate a clear understanding of the present application, the present application will be described in detail below in conjunction with specific embodiments and drawings of the specification.

[0047] Example

[0048] Combined with Figure 1-3 The present embodiment provides a cable retracting structure, including a support frame 1, as shown in the figure, which is a horizontal structure formed by splicing or welding aluminum profiles and is used as a base support structure.

[0049] In order to facilitate the device to change direction, a universal wheel 2 is installed on both sides of the bottom of the first end of the support frame 1. The universal wheel 2 is a structure with a brake part, which can stably stop the device when needed, thereby facilitating the movement or storage of the entire device.

[0050] Secondly, the driving shaft 3 is rotatably mounted on the second end of the support frame 1; that is, a bearing is sleeved on each end of the driving shaft 3, and the two bearings are fixedly connected to the second end of the support frame 1, so that the driving shaft 3 can rotate around the axis.

[0051] In order to facilitate the movement of the entire device, a transmission wheel 4 is installed on the inner side of both ends of the driving shaft 3.

[0052] That is, the bottoms of the two universal wheels 2 and the two transmission wheels 4 are coplanar and located below the support frame 1, thereby facilitating the movement and fixation of the entire device.

[0053] In order to solve the drawbacks of manual winding, the following settings are also made:

[0054] First, a transmission shaft 6 parallel to the driving shaft 3 is arranged above the first end of the support frame 1, and the two ends of the transmission shaft 6 are rotatably mounted on a support rod 7 respectively, and the bottom ends of the two support rods 7 are fixedly connected to the two sides of the top of the first end of the support frame 1 respectively; the two support rods 7 are parallel.

[0055] Next, the disc frame 8 and the slave sprocket 9 are fixedly mounted on the transmission shaft 6, and the main sprocket 5 is fixedly mounted on the driving shaft 3, and a transmission chain 10 is sleeved on the whole formed by the main sprocket 5 and the slave sprocket 9.

[0056] Then, when the transmission wheel 4 rotates, it can drive the disc frame 8 to rotate through the driving shaft 3, the main sprocket 5, the transmission chain 10, the slave sprocket 9, and the transmission shaft 6, thereby avoiding the disadvantages of manual winding.

[0057] A bearing is installed at the top of each support rod 7 for connecting with the transmission shaft 6 to realize the rotational movement of the disc rack 8 and the slave sprocket 9.

[0058] In order to avoid the normal winding caused by the rotation speed of the rack 8 being different from the overall travel speed of the equipment, in this embodiment, the dimensions of the slave sprocket 9, the main sprocket 5, the transmission wheel 4 and the rack 8 are also set to meet the following requirements:

[0059] When the transmission wheel 4 drives the disk rack 8 to rotate through the whole formed by the driving shaft 3, the main sprocket 5, the transmission chain 10, the slave sprocket 9 and the transmission shaft 6, the linear velocity of the transmission wheel 4 is the same as the linear velocity of the outer wall of the disk rack 8.

[0060] For example, in this embodiment, the transmission ratio of the main sprocket 5 and the slave sprocket 9 is 1:6, the number of teeth of the main sprocket 5 is 15, the number of teeth of the slave sprocket 9 is 90, the transmission chain 10 is a single-row roller chain, the ISO chain number is 05B, the pitch p=8, the roller diameter is 5, the pin shaft diameter is 2.31, the pin shaft full width is 8, and the tensile load is 4.4KN, which meets the load requirements of the working condition; the diameter of the disc frame 8 is 892.5mm, the cable diameter is 15mm, and the cable disc The cable center circle diameter D2 after winding is 900mm, the transmission wheel 4 diameter D1 is 150mm, and D2: D1 = z2: z1 = i = 6, which ensures that the linear speed of the transmission wheel 4 and the drum rack 8 are consistent; 30000mm of cable can be completely wound into the drum rack 8 after 11 turns, and the inner width of the drum rack 8 is not less than 165mm. In order to leave a margin of 0.5 times the cable diameter, the inner width of the drum rack 8 is 250mm, and the diameter of the drum rack 8 retaining ring is 1000mm.

[0061] Secondly, in order to prevent the disk rack 8 from rotating when needed, a rotating seat 11 is installed at the bottom of the second end of the support frame 1, and the bottom end of the rotating seat 11 is rotatably connected to a rotating arm 12, and the bottom end of the rotating arm 12 is rotatably installed with an auxiliary wheel 13, and a limit pin 14 and a limit pin 2 15 are fixedly installed on the rotating seat 11. At the same time, the top end of the rotating seat 11 and the bottom end of the rotating arm 12 are also connected through a reset spring group 16.

[0062] In this embodiment, the return spring assembly 16 is composed of two return springs (symmetrically arranged with respect to the rotating seat 11 ), and in some embodiments, it may be composed of one return spring.

[0063] At the same time, when there is no external force, the return spring assembly 16 makes the rotating arm 12 in state 1 or state 2, wherein:

[0064] In state 1, the rotating arm 12 is in a horizontal or nearly horizontal state and fits with the limit pin 14, and the return spring assembly 16 makes the rotating arm 12 always have a tendency to move toward the limit pin 14, and at this time, the surface where the bottom of the transmission wheel 4 and the bottom of the universal wheel 2 are located is below the bottom of the auxiliary wheel 13;

[0065] In state two, the bottom end of the rotating arm 12 is tilted downward and fits with the second limit pin 15, and the return spring assembly 16 makes the rotating arm 12 always have a tendency to move toward the direction of the second limit pin 15, and at this time, the bottom of the transmission wheel 4 and the bottom of the universal wheel 2 are located above the bottom of the auxiliary wheel 13.

[0066] That is, when in state one, the rotating arm 12 is in a retracted state, and when the support frame 1 is pushed, the transmission wheel 4 contacts the ground surface to realize transmission, and the disc rack 8 can be synchronously rotated. At this time, the cable laid on the ground (one end is fixedly connected to the disc rack 8), as the disc rack 8 moves toward the other end of the cable, its main part will gradually be wound on the disc rack 8. This process does not require manual winding, thereby effectively reducing the corresponding workload.

[0067] When in state two, the auxiliary wheel 13 is on the ground, the transmission wheel 4 is suspended, and the whole equipment can move normally when the support frame 1 is pushed, but the transmission wheel 4 is suspended and cannot transmit, so that the disc rack 8 will not rotate, thereby facilitating the transportation of the equipment.

[0068] In order to facilitate the overall movement of the equipment, in this embodiment, a horizontal U-shaped frame 17 is provided above the support frame 1, and the two ends of the horizontal U-shaped frame 17 are fixedly connected to the top ends of the two support rods 7 respectively, and the middle part of the horizontal U-shaped frame 17 is provided above the second end of the support frame 1.

[0069] That is, at this time, nearly a quarter of the disc rack 8 is arranged in the space surrounded by the horizontal U-shaped frame 17, the two support rods 7 and the support frame 1. On the one hand, it is convenient to push the overall movement of the equipment through the horizontal U-shaped frame 17. On the other hand, it can form a protection for the disc rack 8 and prevent the cables arranged on the disc rack 8 from being scattered.

[0070] In order to improve the stability of the equipment, the two ends of the middle part of the horizontal U-shaped frame 17 are fixedly connected to the top of the second end of the support frame 1 through a support member 18 respectively.

[0071] In order to ensure the stability of the device during the implementation process, in this embodiment, the support rod 7 is also made into a long strip structure, and its top end is inclined toward the second end of the support frame 1.

[0072] That is, through the above arrangement, the center of gravity of the rack 8 is set inside the whole formed by the support frame 1, the horizontal U-shaped frame 17, the two support rods 7 and the two support members 18, so as to ensure the stable operation of the equipment.

[0073] In some embodiments, in order to maintain the stability of the device, when the bottoms of the two universal wheels 2 and the bottoms of the two transmission wheels 4 are located on a horizontal plane, the first end of the support frame 1 is higher than the second end thereof.

[0074] At the same time, when the bottom of the two universal wheels 2 and the bottom of the auxiliary wheel 13 in the second state are located on a horizontal plane, the first end of the support frame 1 is higher than the second end thereof.

[0075] Therefore, through the above arrangement, the center of gravity of the device is always located on one side of the center of the support frame 1 when the device is in use (at this time, the support rod 7 and the support frame 1 are perpendicular to each other), thereby ensuring the stability of the device.

[0076] In order to reduce the difficulty of connecting the cable and the disc rack 8, in this embodiment, an insertion hole 19 is opened on the outer wall of the disc rack 8 for winding, and a limiting hole 20 is provided on the side walls of the two vertical walls of the disc rack 8 adjacent to the insertion hole 19, and the insertion hole 19 and the limiting hole 20 are connected to each other through the inner cavity of the disc rack 8.

[0077] That is, one end of the cable can be inserted into the inner cavity of the disc rack 8 through the insertion hole 19 and then inserted into the limiting hole 20 for fixation, thereby reducing the difficulty of connecting the two; the limiting hole 20 and the slave sprocket 9 are respectively arranged on both sides of the disc rack 8, so that the cable head will not affect the operation of the slave sprocket 9.

[0078] Among them, some cables are equipped with aviation plugs at both ends for connecting to the equipment, and can be connected to the external equipment through the limiting hole 20 when in use.

[0079] Through the above arrangement, when it is necessary to coil the cable, first, one end of the cable is inserted from the outside of the first end of the support frame 1 through the insertion hole 19 into the limit hole 20 for fixation. At this time, the main body of the cable is in front of the first end of the support frame 1, and then the middle part of the horizontal U-shaped frame 17 is pushed to make the entire device move toward the direction of the cable body, and at this time the rotating arm 12 is in state one. During the pushing process, the linear speed of the disc frame 8 and the transmission wheel 4 is the same, so that the cable can be actively coiled on the disc frame 8; after the coiling is completed, the rotating arm 12 is operated to put it in state two, and then the entire device can be pushed to move until it reaches the target position, and the brake in the universal wheel 2 is operated to stop and store the entire device.

[0080] When it is necessary to coil multiple layers of cables, after coiling one layer, the rotating arm 12 can be operated to be in state two, and then the entire device can be pushed to move, and the reel 8 can be manually operated to coil the cables in multiple layers, or the rotating arm 12 can still be kept in state one, and the cables can be manually dragged toward the entire device.

[0081] In summary, the cable retraction and release structure provided in the present application can effectively realize cable winding, greatly reduce the manual workload, and improve the convenience of cable winding.
