Description

Technical Field

[0001] The utility model relates to the technical field of steel strand disassembly and anti - detachment equipment, and particularly relates to a steel strand disassembly and anti - detachment device. Background Art

[0002] Before a bundle of steel strands is disassembled, they are wound around each other in circles and tied together into a cylinder shape by a tie. When in use, the tie needs to be removed first to release the restraint on the steel strands, and then the steel strands are extracted (this process is also called wire pay - out).

[0003] However, after the tie is removed, while the restraint on the steel strands is removed, a bundle of steel strands spreads out in a disorderly manner, the whole of the steel strands becomes loose and messy, the wires cross and overlap with each other, which is not convenient for subsequent extraction of the steel strands. Moreover, after cutting off a section of the extracted steel strands, the staff needs to hold one end to prevent the steel strands from rebounding and touching the staff after the extraction is completed. When extracting the steel strands next time, it is necessary to search for the wire pay - out head again, reducing the work efficiency. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a steel strand disassembly and anti - detachment device, which can always limit the steel strands circumferentially, vertically and horizontally, so that the steel strands are always arranged in an orderly manner during the extraction process, facilitating the subsequent extraction of the steel strands.

[0005] The technical solution adopted by the utility model is as follows: a steel strand disassembly and anti - detachment device includes a base. A support assembly for supporting the steel strands and capable of rotating is arranged on the base. The support assembly includes a turntable, a support shaft, and a support member for supporting and abutting against the hollow part of the steel strands. The turntable is located on the base. The support shaft is fixedly connected to the base and rotatably connected to the turntable. One end of the support member is fixedly connected to the turntable, and the other end is rotatably connected to the support shaft. The support shaft is located inside the support member and passes through the support member. A limiting assembly for circumferentially, vertically and horizontally limiting the steel strands is arranged on the support assembly;

[0006] The limiting assembly includes a plurality of first springs, a plurality of second springs, and limiting plates which are circumferentially spaced and abut against the outer edge of the steel strands. One end of the first spring is fixedly connected to the limiting plate, and the other end can be detachably connected to the support member. A plurality of receiving grooves are circumferentially spaced on the turntable. One end of the second spring is connected to the inner wall of the receiving groove, and the other end is connected to the limiting plate. The lower end of the limiting plate can be slidably matched with the inner wall of the receiving groove. Limiting members for limiting the limiting plate are symmetrically arranged at the lower end of the limiting plate;

[0007] When disassembling the steel strand, the first spring and the second spring approach the support shaft under the action of elastic force. The limiting plate is in sliding fit with the inner wall of the receiving groove and can move towards the center of the base. The first spring, the limiting plate, the support member, the second spring, and the turntable cooperate to limit the steel strand circumferentially, vertically, and horizontally.

[0008] Explanation: In this solution, the steel strand refers to a bundle of steel strands. Before being disassembled, the bundle of steel strands is tied together by a tie strap and is in a cylindrical shape.

[0009] Principle of the technical solution:

[0010] The limiting plate is limited at the outer edge of the turntable through a limiting member, and the second spring is stretched. An un-disassembled bundle of steel strands is placed on the turntable. The support member is located in the hollow part of the bundle of steel strands and abuts against the steel strands. The limiting plate abuts against the outer edge of the bundle of steel strands. Then, the first spring on the corresponding limiting plate is connected to the support member, so that the bundle of steel strands is located in the space enclosed by the turntable, the limiting plate, the first spring, and the support member. The limiting plate, the turntable, and the support member cooperate to limit the bundle of steel strands circumferentially, and the first spring and the turntable cooperate to limit the bundle of steel strands vertically and horizontally. Remove the tie strap on the bundle of steel strands. Since the steel strands are limited circumferentially, vertically, and horizontally, the steel strands maintain the state when they are bound by the tie strap;

[0011] When extracting a section of steel strand, as the steel strand is extracted, the radial diameter of the bundle of steel strands decreases. Remove the limiting member. Under the action of elastic force, the first spring and the second spring drive the limiting plate to move towards the center of the base, and drive the limiting plate to be in sliding fit with the inner wall of the receiving groove, so that the limiting plate always abuts against the outer edge of the bundle of steel strands, thereby always limiting the bundle of steel strands circumferentially, vertically, and horizontally.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The limiting member of the present utility model can limit the limiting plate, ensuring that the second spring is stretched in the initial state, exposing the turntable, creating a placement space for the steel strands. The receiving groove can guide the limiting plate and accommodate the second spring to ensure the normal use of the second spring. The second spring, the limiting plate, the first spring, the turntable, and the support member cooperate to limit the steel strands circumferentially, vertically, and horizontally, and can always abut against the outer edge of the steel strands as the diameter of a bundle of steel strands gradually decreases during the extraction of the steel strands, thereby always limiting the steel strands circumferentially, vertically, and horizontally, making the steel strands always placed in an orderly manner during the extraction process, facilitating the subsequent extraction of the steel strands.

[0014] As a preferred embodiment of the present utility model, the limiting member includes a connecting groove located on the turntable, a limiting portion connected to the limiting plate, and a pin that can pass through the limiting portion and be inserted into the connecting groove. The limiting portion includes a connecting plate and a cylinder. One end of the connecting plate is connected to the limiting plate, and the other end is connected to the cylinder. The pin passes through the cylinder and is inserted into the connecting groove.

[0015] Beneficial effect: The cooperation of the bolt, the connecting groove, the connecting plate and the cylinder makes the limiting operation of the limiting plate convenient.

[0016] As a preferred embodiment of the present utility model, the support member includes a first connecting ring, a second connecting ring, connecting members arranged at circumferential intervals, and first connecting columns arranged at circumferential intervals. The first connecting ring is rotatably connected to the support shaft. One end of the connecting member is connected to the outer wall of the first connecting ring, and the other end is connected to the inner wall of the second connecting ring. One end of the first connecting column is connected to the second connecting ring, and the other end is connected to the turntable. A hook is provided at the end of the first spring away from the limiting plate, and the hook can be hung on the second connecting ring.

[0017] Beneficial effect: The first spring is connected to the second connecting ring through the hook, which facilitates the quick disassembly and connection of the first spring and the second connecting ring.

[0018] As a preferred embodiment of the present utility model, the connecting member includes symmetrically arranged second connecting columns, and the hook is located between the two second connecting columns when hanging on the second connecting ring.

[0019] Beneficial effect: The two second connecting columns can limit the hook, ensuring that the position of the hook is fixed during operation and improving safety.

[0020] As a preferred embodiment of the present utility model, an elastic band is provided between the two limiting plates.

[0021] Beneficial effect: Increase the circumferential restraint on the steel strand.

[0022] As a preferred embodiment of the present utility model, a through hole is provided on the limiting plate, and a shielding plate for shielding the through hole is rotatably connected to the outer surface of the limiting plate. Third springs connected to the limiting plate are symmetrically provided at one end of the shielding plate away from the connection between the limiting plate and the shielding plate. The outer edge of the through hole near the third spring is serrated.

[0023] In this solution, when the steel strand is not extracted, the end of the shielding plate connected to the third spring is close to the limiting plate. When the steel strand is extracted, the end of the steel strand sequentially passes through between the through hole, the shielding plate and the limiting plate. Since the shielding plate is rotatably connected to the outer surface of the limiting plate, the end of the steel strand presses the end of the shielding plate away from the limiting plate, causing the third spring to stretch. The outer edge of the shielding plate away from the serrated through hole is used to extract the steel strand. When the extraction stops, the end of the steel strand is slowly moved close to the connection between the limiting plate and the third spring. Under the elastic force of the third spring, the shielding plate is driven to approach the limiting plate, and the end of the steel strand is located between the serrated outer edge of the through hole and the shielding plate, and the end of the steel strand is limited.

[0024] Beneficial effects: The baffle is rotatably connected to the outer surface of the limiting plate, and the cooperation between the baffle and the third spring can ensure that the baffle rotates and returns to its initial position. In addition, at the end of the baffle away from the connection between the baffle and the limiting plate, the outer edge of the through hole is serrated. When the steel strand is located between the baffle and the limiting plate, the baffle and the outer edge of the through hole limit the steel strand, and the serrations catch the steel strand, thereby limiting the steel strand again, preventing the wire end from rebounding and touching the staff, facilitating quickly finding the wire end of the steel strand next time, and improving work efficiency.

One end of the caster is connected to the turntable 201, and the other end is in rolling cooperation with the base 1. A bundle of steel strands has a certain weight. When pulling the steel strands, a bundle of steel strands needs to rotate. The casters can assist the bundle of steel strands placed on the turntable 201 to rotate quickly and save effort. The turntable 201 is located on the base 1. A plurality of receiving grooves 204 are circumferentially spaced on the turntable 201.

[0035] A limiting assembly for circumferentially and vertically limiting the steel strands is provided on the support assembly. The limiting assembly includes a plurality of first springs 301, a plurality of second springs 302, and a limiting plate 303 circumferentially spaced apart and abutting against the outer edge of the steel strands. One end of the first spring 301 is fixedly connected to the limiting plate 303, and the other end is detachably connected to the support member 203. In this embodiment, a hook 3011 is provided at the end of the first spring 301 far from the limiting plate 303. The hook 3011 can be hung on the second connection ring 2032. When the hook 3011 is hung on the second connection ring 2032, it is located between two second connection columns.

[0036] The second spring 302 is located in the receiving groove 204. One end of the second spring 302 is connected to the inner wall of the receiving groove 204, and the other end is connected to the limiting plate 303. The lower end of the limiting plate 303 is slidably matched with the inner wall of the receiving groove 204. Limiting members 304 for limiting the limiting plate 303 are symmetrically provided at the lower end of the limiting plate 303.

[0037] In this embodiment, the limiting member 304 includes a connecting groove 3041 located on the turntable 201, a limiting portion 3042 connected to the limiting plate 303, and a pin 3043 that can pass through the limiting portion 3042 and be inserted into the connecting groove 3041. The limiting portion 3042 includes a connecting plate and a cylinder. One end of the connecting plate is connected to the limiting plate 303, and the other end is connected to the cylinder. The pin 3043 passes through the cylinder and is inserted into the connecting groove 3041.

[0038] In this embodiment, a plurality of connecting grooves 3041 can be arranged at intervals along the length direction of the receiving groove 204, so as to limit a bundle of steel strands with different diameters, thereby improving the scope of application.

[0039] As Figures 2-3 shown, an elastic band 305 is provided between the two limiting plates 303. A through hole 306 is provided on the limiting plate 303. A baffle plate 307 that can block the through hole 306 is rotatably connected to the outer surface of the limiting plate 303. Symmetrically arranged at one end of the baffle plate 307 away from the connection with the limiting plate 303 are third springs 308 connected to the limiting plate 303. The outer edge of the through hole 306 near the third spring 308 is serrated. In this embodiment, the baffle plate 307 can rotate horizontally by 180 degrees.

[0040] When disassembling the steel strands, the first spring 301 and the second spring 302 move closer to the support shaft 202 under the action of elastic force. The limiting plate 303 is in sliding fit with the inner wall of the receiving groove 204 and can move towards the center of the base 1. The first spring 301, the limiting plate 303, the support member 203, the second spring 302, and the turntable 201 cooperate to limit the steel strands circumferentially and vertically.

[0041] Specific usage steps (when the bundle of steel strands is not disassembled, it is in a cylindrical shape):

[0042] The pin 3043 passes through the cylinder on the limiting portion 3042 and the connecting groove 3041 in sequence to limit the limiting plate 303 on the turntable 201, and the second spring 302 is stretched. Then, place the bundle of non-disassembled steel strands on the turntable 201. The first connecting column 2034 passes through the hollow part of the bundle of steel strands and abuts against the hollow part of the bundle of steel strands. The limiting plate 303 abuts against the outer edge of the bundle of steel strands. Then, pull the end of the first spring 301 with the hook 3011, so that the hook 3011 is hooked on the second connecting ring 2032 and is located between the two second connecting columns of the connecting member 2033. At this time, the limiting plate 303, the elastic band 305, and the first connecting column 2034 respectively abut against the outer edge and the hollow part of the bundle of steel strands vertically. The turntable 201 and the first spring 301 respectively abut against the lower and upper parts of the bundle of steel strands. Thus, the first spring 301, the limiting plate 303, the turntable 201, and the first connecting column 2034 cooperate to limit the bundle of steel strands circumferentially and vertically;

[0043] When extracting the steel strand, first remove the bolt 3043. The end of the steel strand passes through the through-hole 306, the shielding plate 307 and between the limiting plate 303 in sequence, and press the shielding plate 307, so that one end of the shielding plate 307 away from the connection between the shielding plate 307 and the limiting plate 303 rotates horizontally away from the limiting plate 303, the third spring 308 stretches, and start to extract the steel strand outwards, and pull the bundle of steel strands to rotate horizontally on the turntable 201 (at this time, the casters drive the turntable 201 to rotate horizontally). The diameter of the bundle of steel strands decreases. Under the action of elastic force, the first spring 301 and the second spring 302 move towards the center of the base 1. The first spring 301 and the second spring 302 drive the limiting plate 303 to move towards the center of the base 1 at the same time. The limiting plate 303 is simultaneously in sliding fit with the inner wall of the receiving groove 204, ensuring that the limiting plate 303 always abuts against the outer edge of the bundle of steel strands during the extraction of the steel strand, and ensuring the effective limiting of the steel strand at all times;

[0044] When the extraction is completed, hold the end of the steel strand and approach the outer surface of the limiting plate 303. Under the action of elastic force, the third spring 308 drives the shielding plate 307 to rotate horizontally. One end of the shielding plate 307 away from the connection between the shielding plate 307 and the limiting plate 303 approaches the limiting plate 303. The shielding plate 307 and the limiting plate 303 abut against and limit the end of the steel strand. The outer edge of the through-hole 306 is serrated and inserted into the end of the steel strand to clamp the end of the steel strand, so as to stably limit the end of the steel strand.

[0045] The above embodiments are only the preferred embodiments of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
