Description

Technical Field

[0001] The present disclosure relates to the technical field of cored wire equipment, and particularly relates to a vertical wire pay-off stand. Background Art

[0002] The production process of seamless welded pure calcium cored wire is uncoiling - storage cage - forming - welding - sizing - primary horizontal winding - annealing - vertical wire pay-off stand (secondary rewinding) - straightening - secondary winding.

[0003] During production, in the annealing process, the wire bundle of seamless pure calcium cored wire is placed upright. After annealing, it is necessary to hoist the upright wire bundle onto the vertical wire pay-off stand. During the hoisting process, the height of the lifting tool plus the height of the wire bundle and the height of the vertical wire pay-off stand, the wire bundle is hoisted to a relatively high height, posing a greater safety hazard. Moreover, the hoisting operation is unstable and it is not easy to position the wire bundle during the falling process; after the wire bundle falls, it cannot be accurately located at the center of the wire pay-off stand, and the operation is unstable during the wire paying-off process; when the wire bundle rotates, due to the large inertia, it is not easy to stop rotating, resulting in problems such as seamless coil loosening, mutual entanglement, and wire chaos.

[0004] The existing horizontal wire pay-off stand can play a good role in paying off the coiled and stacked steel bars, but it occupies too much area and has great limitations in space when in use. In the existing vertical wire pay-off stand, the hoisting height is still relatively high during the hoisting process, and the hoisting operation process is unstable, resulting in inaccurate positioning; the wire bundle is not easy to position and causes problems such as wire chaos, seamless coil loosening, and mutual entanglement, and it is prone to lateral overturning. Summary of the Invention

[0005] The purpose of the present invention is to address the defects existing in the prior art, and provide a vertical wire pay-off stand to prevent lateral overturning and prevent the occurrence of loose and chaotic wire reels. It adopts a vertical storage structure, with the bottom plate of the wire bundle end face contacting the turntable to form a surface-to-surface contact, facilitating direct hoisting and placement during transportation, and ensuring the stability after placement, solving the problem of high hoisting caused by adjusting the wire bundle posture, and improving the operation stability and hoisting positioning accuracy.

[0006] To solve the above problems, the following solutions are adopted:

[0007] A vertical wire pay-off stand includes a base support device and a turntable support.

[0008] The base support device includes a central rotating shaft, the turntable is fixed to the top of the central rotating shaft, and a positioning sleeve is fixedly installed on the turntable.

[0009] The turntable support includes a bottom plate, on which a support frame is hingedly connected and a central sleeve with a height value lower than that of the support frame is fixedly installed. An arm is slidably sleeved outside the central sleeve, and the arm is hinged to the support frame through a connecting rod.

[0010] The turntable bracket is installed on the base support device by sleeving its central sleeve on the positioning sleeve in the base support device.

[0011] Further, a limit block is provided at the top end of the central sleeve, and a limit hole is provided on the jib; the central sleeve is slidably connected to the limit hole of the jib through the limit block; the jib slides along the central sleeve, and the driving link drives the support frame to close or expand towards the central sleeve.

[0012] Further, the base support device includes a base frame, a plate platform is fixed on the base frame, a central rotating shaft is arranged inside the plate platform, and one end of the central rotating shaft is fixed on the base frame.

[0013] Further, a hydraulic brake and a brake disc are arranged inside the plate platform, and the brake disc is used to brake the central rotating shaft.

[0014] Further, brackets are evenly arranged around the outside of the plate platform, and idler wheels are arranged inside the brackets.

[0015] Further, the bottom of the turntable is located above the idler wheels and is in contact connection with the idler wheels.

[0016] Further, the bottom end of the support frame is hinged on the bottom plate, and the middle part of the support frame is hinged to the jib through a connecting rod.

[0017] Further, the support frame includes a support frame body for placing wire bundles, and a bending part is arranged at the top of the support frame body.

[0018] Further, a lifting ring is arranged at the top of the jib, and the lifting ring and the jib are of an integral structure.

[0019] Further, a plurality of inclined braces are welded on the outer circumferential direction of the bottom plate and are inclined upwards.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are:

[0021] (1) Aiming at the problems that the current wire pay-off rack is prone to lateral overturning and loose coil and disordered wire, a vertical storage structure is adopted, and the bottom plate of the wire bundle end face contacts the turntable to form a surface-to-surface contact, which is convenient for direct hoisting and placement during transportation and ensures the stability after placement. The heights of the central sleeve and the positioning sleeve are much smaller than the height dimension of the wire bundle. Only need to hoist the turntable bracket and install the central sleeve on the positioning sleeve, the hoisting height is greatly reduced, which is convenient for operation and eliminates dangerous factors, and improves the operation stability and hoisting positioning accuracy.

[0022] (2) Adopting a hydraulic brake and a brake disc to brake the central rotating shaft can achieve rapid braking and avoid disordered wire.

[0023] (3) A plurality of inclined braces are welded to the outer side of the bottom of the central sleeve, which are arranged obliquely upward. A steel ring is welded to the outer sides of the plurality of inclined braces. A wire storage bin is formed between the steel ring, the inclined braces and the central sleeve to temporarily store the loosened seamless wire, preventing the loosened seamless wire from falling outside the bottom plate, resulting in the dropped seamless wire winding around the base frame, the seamless wire being pulled off or the vertical wire pay-off rack toppling over.

[0024] (4) The bottom of the support frame is hinged to the bottom plate and has the same inner diameter size as the wire bundle. When the support frame is not hoisted, the boom is at the lowermost end of the turntable support. The upper part of the support frame is in a contracted state, and its outer dimension is much smaller than the inner diameter size of the wire bundle, facilitating sleeving during wire bundle hoisting. When the turntable support is hoisted, the boom slides along the central sleeve, and the limit arm moves in the limit hole. The upper part of the support frame is expanded outward by the connecting rod to adjust the wire bundle to be in the central position, with accurate positioning and ensuring smooth operation.

[0025] (5) The vertical wire pay-off rack not only occupies a small space but also can greatly reduce the hoisting height during hoisting, solves the problem of unstable operation during hoisting, has accurate positioning, and improves production efficiency. Description of the Drawings

[0032] Embodiment 1

[0033] In a typical embodiment of the present invention, as Figures 1 - 4 shown, a vertical wire pay-off rack is provided.

[0034] The present invention discloses a vertical pay-off frame, comprising a base support device and a turntable 7 bracket; the base support device and the turntable 7 bracket are sleeved and connected through a central sleeve 10 of the base support device and a positioning sleeve 8 of the turntable 7 bracket, so that the turntable 7 bracket is fixedly installed on the base support device.

[0035] like Figure 1 As shown, the base support device includes a base frame 1, which is a frame structure, and a bottom plate 9 is arranged at the bottom. The bottom plate 9 can be composed of a solid plate with a rectangular or circular cross-sectional shape. The specific shape is not limited and can be adaptively changed according to the construction site. In this embodiment, the bottom plate 9 is arranged with a rectangular structure.

[0036] A platform is vertically arranged on the bottom plate 9, and the platform can be specifically adjusted according to the shape of the bottom plate. When the cross-sectional shape of the bottom plate 9 is circular, the platform can be set as a hollow cylindrical structure. When the bottom plate 9 is a rectangular structure, the platform above it is set as a hollow cubic structure. In this embodiment, since the bottom plate 9 is a rectangular structure, the platform is set as a hollow cubic structure.

[0037] A central rotating shaft 2 is arranged at the center of the bottom plate 9 in the platform, and the central rotating shaft 2 can realize rotational movement. Bearings 3 are arranged at both ends of the axial direction of the central rotating shaft 2. The central rotating shaft 2 is rotatably mounted in the bottom plate 9 and the platform through the bearings 3.

[0038] A turntable 7 is fixedly connected above the central rotating shaft 2. When the central rotating shaft 2 rotates, the turntable 7 above the central rotating shaft 2 is driven to rotate.

[0039] A brake disc 4 is fixedly installed in the circumferential direction of the central rotating shaft 2, and the brake disc 4 is located in the lower axial position of the central rotating shaft 2 in the platform. The brake disc 4 is used to brake the central rotating shaft 2 when it rotates. A hydraulic brake 5 is also provided in the platform, and the installation position of the hydraulic brake 5 corresponds to the brake disc 4, and is used to hold the brake disc 4 to brake the central rotating shaft 2.

[0040] Brackets are evenly arranged around the outer side of the platform near the top, and the brackets are arranged at the four corners of the top of the base platform to stably support the turntable 7. The cross section of the bracket is triangular, and two parallel tugboat 6 brackets are fixed above the bracket at a certain distance, and the distance between them is to ensure that the tugboat 6 is located in the tugboat 6 bracket and can rotate freely.

[0041] A towing wheel 6 is respectively arranged at each of the four end parts of the plate table. The turntable 7 is located above the towing wheel 6, and the towing wheels 6 are arranged at the four corners, aiming to keep the turntable 7 above the towing wheels 6 at the same height all the time, avoiding uneven stress caused by the wire bundle not being placed at the center position of the vertical pay-off stand, so as to maintain smooth rotation.

[0042] A positioning sleeve 8 is fixedly installed on the turntable 7, and the positioning sleeve 8 is fixed at the center position of the turntable 7. The positioning sleeve 8 includes a columnar body and a positioning tip located above the columnar body. The positioning tip is set as a pointed structure with a cross-section in the shape of a cross. The design of the pointed structure aims to achieve centering with the central sleeve 10 in the turntable 7 bracket, facilitating the central sleeve 10 suspended during hoisting to be sleeved outside the positioning sleeve 8, and avoiding the central sleeve 10 getting stuck on the positioning sleeve 8 and unable to fall smoothly during the sleeving process.

[0043] As Figure 2 shown, the turntable 7 bracket includes a bottom plate 9. A central sleeve 10 is arranged at the center position of the bottom plate 9. When the turntable bracket is installed on the base support device, the bottom plate 9 of the turntable bracket contacts and connects with the turntable 7 of the base support device.

[0044] The middle part of the bottom plate 9 is a flat structure, and the edge of the bottom plate 9 bends towards the center at a certain angle in the circumferential direction of the bottom plate 9. The cross-section of the bottom plate 9 is in a C-shaped structure. The structure where the edge bends towards the center is to prevent the cored wire falling on the support frame 12 from rotating out of the outside of the bottom plate 9 and play a role in blocking at a certain height.

[0045] A lifting ring 11 is fixedly connected to the top of the lifting arm 14 sleeved outside the central sleeve 10. The lifting ring 11 is arranged on the lifting arm 14, and the lifting ring 11 and the lifting arm 14 are of an integrated structure. A connecting rod 15 is arranged at a position near the top on the outer circumferential surface of the lifting arm 14. The connecting rods 15 are evenly arranged in the circumferential direction of the lifting arm 14. One end of the connecting rod 15 is hinged to the lifting arm 14, and the other end is hinged to the inner wall of the support frame 12. The function of the connecting rod 15 is to drive the lifting arm 14 to move up or down when the lifting ring 11 is lifted or lowered, drive the connecting rod 15 to rotate in the corresponding direction, and realize the support frame 12 to converge towards the central sleeve, that is, to contract or expand radially.

[0046] A support frame 12 is provided on the bottom plate 9. The lower end of the support frame 12 is hinged to the bottom plate 9, and the middle part of the support frame 12 is hinged to the lifting arm 14 through a connecting rod 15. A central sleeve 10 is welded on the bottom plate 9, and the lifting arm 14 is sleeved outside the central sleeve 10. The support frame 12 includes a support frame body in the shape of a hollow cylindrical structure. A bending part is provided at the top of the support frame body, and the bending part is bent inward from one side of the support frame body. A core wire is wound outside the support frame 12, and the wire bundle is wound outside the support frame body. The bending part of the support frame is bent inward at a certain angle to facilitate taking and placing the wire bundle.

[0047] The central sleeve 10 and the lifting arm 14 are located inside the support frame 12 at a certain height lower than the support frame 12, and the height value of the lifting ring 11 is much smaller than the height value of the support frame 12. The lifting ring 11 above the lifting arm 14 is pulled up by a lifting tool, the support frame 12 expands outwards, the wire bundle is adjusted to be at the center position of the turntable support, and the entire wire bundle is driven to be lifted under the action of the inner support structure, thereby reducing the lifting height of the entire wire bundle.

[0048] When not hoisted, the outer diameter of the support frame 12 is 50 - 100 mm smaller than the inner diameter of the wire bundle, so that the wire bundle can be more conveniently installed on the support frame 12. A number of inclined braces are welded on the outer circumferential direction of the bottom plate and are inclined upwards. A steel ring 17 is welded outside the number of inclined braces. A wire storage bin is formed between the steel ring 17, the inclined braces and the central sleeve 10 to temporarily store the loosened seamless wire, preventing the loosened seamless wire from falling outside the bottom plate 9, causing the dropped seamless wire to wind around the base frame 1, the seamless wire to be broken or the vertical wire dispensing rack to tip over. The steel ring 17 is used to protect the surface of the core wire from being scratched. Since the heights of the central sleeve 10 and the lifting arm 14 are much smaller than the height dimension of the wire bundle, only the turntable 7 support needs to be hoisted to install the central sleeve 10 onto the positioning sleeve 8, and the lifting height is greatly reduced, which is convenient for operation and eliminates dangerous factors.

[0049] After hoisting the turntable 7 support with the wire bundle, the central sleeve 10 of the turntable 7 support is sleeved outside the positioning sleeve 8 to realize the docking of the central sleeve 10 and the positioning sleeve 8, and then it is slowly lowered. The central sleeve 10 completely covers the outside of the positioning sleeve 8, and the central sleeve 10 is installed on the turntable 7 to realize the wire dispensing process.

[0050] As Figure 3 shown, it is a schematic assembly structure diagram of the base support device and the turntable 7 support. At this time, the base support device and the turntable 7 support are completed for docking. During the entire wire dispensing process, only the lifting ring 11 in the turntable 7 support needs to be hoisted to realize the lifting of the wire bundle. The lifting ring 11 and the lifting arm 14 are of an integrated structure. The lifting arm 14 is sleeved with the central sleeve and the sliding distance is limited. In this way, not only the entire lifting process is reduced, but also accurate centering wire dispensing can be realized.

[0051] As Figure 4As shown in the figure, it is a schematic application diagram of the device of the present invention. The alloy wire bundle is located outside the support frame. At this time, the turntable support and the base support device have been assembled. The turntable support with the wire bundle is installed outside the base support device. When it is necessary to brake the central rotating shaft 2, the turntable connected to the central rotating shaft 2 brakes, and the central sleeve 10 fixedly connected to the turntable stops rotating. The positioning sleeve 8 docked with the central sleeve 10 brakes accordingly. The bottom plate fixedly connected to the turntable support and the central sleeve 10 brakes, the support frame 12 on the bottom plate brakes, and the wire bundle outside the support frame 12 stops winding. When it is necessary to continue winding, the brake disc is loosened through the hydraulic brake, and the brake disc releases the central rotating shaft 2, realizing the rotation of the central rotating shaft 2 driving the turntable support.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
