Description

Technical Field

[0001] The utility model relates to the technical field of cable pay-off racks, in particular to an active cable pay-off platform. Background Art

[0002] Wires and cables contain one or more insulating cores and a coating covering the cores. That is, during the production and processing of wires and cables, the cores are laid out first, and then one or more insulating layers are added to the outer layer of the cores. During the process of setting the insulating layers, the cores or cable cores on the reel need to be laid out.

[0003] For example, the patent application number "202122474552.4" proposes an active cable pay-off platform, which places the pay-off reel between the upper rotating shaft and the lower rotating shaft, and an anti-slip sleeve is provided at the contact point. Such a disadvantage is also obvious, because the wire cores are all made of metal, and after winding them on the pay-off reel, they are not only large in size, but also heavy. In this way, when the wire on the pay-off reel is pulled out first, there is no driving mechanism to drive the pay-off reel to drive the pay-off reel to follow the rotation, resulting in the only way to pull the cable to drive the pay-off reel to rotate passively, which makes it inconvenient for the pay-off reel to rotate, causing the pulled-out wire core to be too tight. To this end, we propose an active cable pay-off platform. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0032] See also Figures 1 to 6 The utility model provides a technical solution: an active cable pay-off platform, comprising two parallel brackets 19, the bottoms of the brackets 19 are respectively arranged on the base, and the two brackets 19 are connected by at least one connecting beam 7, so that the brackets can be more stable; Figure 1 As shown, the specific structure of the base is that the base includes a first strip base 1, the bottoms of two brackets 19 are respectively installed on the first strip base 1, and the two ends of the first strip base 1 are respectively connected to the second strip base 18. In actual use, the second strip base 18 is used to support the bracket 19, and the first strip base 1 and the second strip base 18 form an "H"-shaped frame and can be placed on the ground.

[0033] In the present invention, each bracket 19 is provided with a lifting mechanism on its side, one end of the lifting mechanism is connected to an L-shaped support arm 3, and the bottom of the L-shaped support arm 3 is arranged horizontally. Figure 1 As shown, the end of the L-shaped support arm 3 extends to the outside of the bracket 19 and is located above the second strip base 18;

[0034] A mounting seat 16 is horizontally installed on the bottom end of the L-shaped support arm 3, and each mounting seat 16 is provided with two parallel support rollers 2. Both ends of the support roller 2 are rotatably installed in the first bearing seat 17, and the first bearing seat 17 is set on the mounting seat 16, so that the support roller 2 can rotate freely.

[0035] In order to enable the support roller 2 to rotate, a driving mechanism for driving the support roller 2 to rotate is specially designed. The driving mechanism is a motor mounting plate 25 arranged on the side where the two L-shaped support arms 3 are away from each other. A driving motor 14 is installed on the motor mounting plate 25. The rotating shaft of the driving motor 14 is located on one side of the end of the support roller 2 and the two are perpendicular to each other. A bevel gear 20 is connected to the rotating shaft of the driving motor and one end of the support roller 2. The two bevel gears 20 are vertically meshed. In actual use, the diameter of the bevel gear 20 arranged at the end of the support roller 2 is larger than the diameter of the bevel gear 20 arranged on the rotating shaft of the driving motor. In this way, a reduction mechanism in which a small gear drives a large gear can be formed, so that the driving motor can drive a large load with a small torque. Therefore, when the motor mounting plate 25 rotates, the supporting roller 2 connected thereto can be driven to rotate;

[0036] The specific lifting process of the pay-off platform is to make the L-shaped support arm 3 reach the lowest position under the drive of the lifting mechanism, so that the height of the L-shaped support arm 3 is below half the height of the winding reel, and the support shaft 23 is inserted into the winding reel 21, and step shafts 24 are coaxially provided at both ends of the support shaft 23, and the step shafts 24 are respectively placed between the two support rollers 2. The surface of the support shaft 23 is provided with an external thread structure, and two locking disks 22 are threadedly connected to the support shaft 23. The winding reel 21 located on the support shaft 23 is clamped by the two locking disks 22, so that the winding reel and the support shaft can be fixed;

[0037] Then the lifting mechanism is controlled to lift the L-shaped support arm 3. As the L-shaped support arm 3 gradually rises, the support roller 2 gradually lifts the stepped shaft 24, so that the stepped shaft 24 is seated on the support roller, and drives the stepped shaft 24 to be lifted to a certain height. The lifted height allows the winding reel to leave the ground. Then the drive motor 14 is controlled to rotate, and the drive motor 14 drives the support roller 2 to rotate (a gap is provided between the two support rollers 2), so that the support roller 2 drives the stepped shaft 24 to rotate, so that the cable on the winding reel 21 is actively unwound.

[0038] Furthermore, in order to prevent the bevel gear 20 from being entangled with foreign objects during the transmission process, a protective cover 26 is provided on each motor mounting plate 25, and the protective cover 26 covers the bevel gear 20 therein, so that the bevel gear 20 can be prevented from being exposed.

[0039] At the same time, in order to drive the motor more stably, such as Figure 3 As shown, the rotating shaft of the driving motor 14 is rotatably arranged in the support 15, and the bottom of the support 15 is connected to the motor mounting plate 25, so that the support 15 supports the rotating shaft of the driving motor.

[0040] The detailed structure of the lifting mechanism will be described below, that is, the lifting mechanism includes a lifting screw 10 located on the side of the bracket 19 away from the L-shaped support arm 3, one end of the lifting screw 10 is rotatably connected to the motor fixing seat 9, and the motor fixing seat 9 is provided with a lifting motor 8 connected to the lifting screw, and the other end of the lifting screw 10 is rotatably connected to the second connecting seat 13, and the second connecting seat 13 and the motor fixing seat 9 are both connected and fixed to the bracket 19;

[0041] A strip support 12 is provided on the side where the two brackets 19 are away from each other, and a moving seat 11 is provided on the end of the strip support 12 close to the lifting screw 10, and the lifting screw 10 passes through the moving seat 11 and the two are threadedly connected; a support guide rail 6 is provided on the side of the bracket 19 close to the L-shaped support arm 3, and a matching slider 5 is slidably provided on each support guide rail 6, and the side surfaces of the slider 5 are connected to the first connecting seat 4, and the first connecting seat 4 is respectively fixed to the strip support 12, and the L-shaped support arm 3 is installed on the end of the strip support 12, and the L-shaped support arm 3 is specifically installed on the end of the strip support 12 close to the slider, so that the slider can maximize the support force of the L-shaped support arm; Figure 1 As shown, one end of the strip support 12 is threadedly connected to the lifting screw 10 through the moving seat 11, and the strip support 12 is connected to the slider through the first connecting seat 4, so that the strip support 12 can be stably lifted and lowered along the bracket under the drive of the lifting screw.

[0042] It should be noted that two adjacent support rollers 2 do not contact each other, and a plurality of transmission teeth are provided on the support roller 2 and the stepped shaft 24, so that the surfaces of the support roller 2 and the stepped shaft 24 form a gear structure, or gears can be directly installed on the support roller 2 and the stepped shaft 24, and when the stepped shaft is placed on the support roller, the two 24 are meshed, so that slippage between the support roller 2 and the stepped shaft 24 can be avoided;

[0043] Furthermore, in order to prevent the step shaft from jumping during the transmission process, a pressing mechanism is provided above both ends of the support shaft 23 to press it. Figure 5 As shown, the pressing mechanism includes an L-shaped support 27 arranged at one end of each first connecting seat 4 away from the strip support 12, the L-shaped support 27 is located above the support shaft 23, and a third connecting seat 30 is installed at the end of the L-shaped support 27, and a telescopic mechanism 28 and at least one guide shaft 29 are installed in the third connecting seat 30, and the telescopic mechanism 28 is one of a cylinder, a hydraulic cylinder or an electric push rod;

[0044] The bottoms of the telescopic mechanism 28 and the guide shaft 29 are both mounted on the fourth connecting seat 31. Figure 6As shown, two clamping wheels 33 with axes parallel to the support shaft 23 are installed at the bottom of the fourth connection seat 31. Both ends of the clamping wheel 33 are rotatably installed in the second bearing seat 32. The second bearing seat 32 is fixed below the fourth connection seat 31. The two clamping wheels 33 are symmetrically distributed above the support shaft 23. In the specific operation process, in the initial state, the clamping wheel 33 is placed above the support shaft 23 under the drive of the telescopic mechanism 28. When the support shaft 23 is lifted and before rotating, the telescopic mechanism 28 is controlled to drive the clamping wheel 33 to descend and press on the support shaft, so that the gap between the clamping wheel 33 and the support shaft is matched, so that the support shaft can be prevented from jumping when it rises. When the winding reel is finished, the clamping wheel 33 is lifted to remove the support shaft for the next wire-releasing operation.

[0045] Based on the above embodiment, further optimization can be performed. For the convenience of movement, brake universal wheels can be provided at both ends of the bottom of the second strip base 18, so that both positioning and movement are possible.

[0046] Based on the above embodiment, further optimization can be performed, such as Figure 1 At the point indicated by the middle arrow A, a control switch can be installed on the top of the side of the motor fixing seat 9. The control switch includes a switch for controlling the forward and reverse rotation of the lifting motor 8, a switch for controlling the rotation of the drive motor 14, and a switch for controlling the extension and retraction of the telescopic mechanism, which is convenient for the operator to operate.

[0047] Based on the above embodiment, further optimization can be performed, such as Figure 7 As shown, in actual use, at least one winding reel can be put on the support shaft. If multiple strands of wire are to be paid out, the pay-off platform can be arranged in a plurality of rows and placed side by side.
