Description

Technical Field

[0001] The utility model belongs to the application field of steel strand retracting and releasing, and specifically relates to a steel strand retracting and releasing system for automatically laying isolation plates. Background Art

[0002] The steel strand jack is used to hoist large and overweight objects such as large petrochemical industrial reactors and prefabricated bridge deck sections. The function of the steel strand jack is only to provide an upward lifting force to pull the steel strand upward. The steel strand passes through the lower part of the jack and comes out from the upper part. Depending on the specifications of the steel strand jack, each steel strand jack will be equipped with several or dozens of steel strands, and the length of each steel strand ranges from tens of meters to thousands of meters. The steel strand coming out of the upper part of the jack needs to be wound, retracted and stored. The device for retracting and releasing the steel strand must not only operate efficiently, but also ensure that the steel strand is not tangled in the storage drum, and must not cause damage or destruction to the steel strand.

[0003] At present, the steel strand retracting and releasing devices used include non-powered steel strand retracting and releasing devices and powered steel strand retracting and releasing devices. The non-powered steel strand retracting and releasing device is similar to a reel that rotates freely around an axis. After the steel strand comes out from the upper part of the steel strand jack, it is wound onto the non-powered retracting and releasing device through a wire device. Since the hardness of the steel strand is relatively large, after the jack pulls out the steel strand, the steel strand can push the non-powered steel strand retracting and releasing device to rotate and realize the winding and retracting action of the steel strand. Since the non-powered retracting and releasing device rotates passively and is not controlled, there are uncertainties when winding the steel strand. The steel strand may be damaged due to the disordered arrangement of the steel strand on the wire-releasing device caused by the imperfect arrangement of the steel strand. This device is suitable for passive retracting and releasing of steel strands when the steel strand is short.

[0004] The power-retractable steel strand device includes a relatively complete power-retractable steel strand device and a simple power-retractable steel strand device. The complete power-retractable steel strand device has complete functions, the rope arrangement is relatively neat, and it can realize automatic operation, but the cost is generally high. In order to reduce costs, a simple power-retractable steel strand device is usually used, but the device will also have the problem of inter-layer rope disorder during use, especially when used as a winch. When the steel strand is pre-wound onto the drum, it is wound layer by layer from the outer surface of the drum. The drum rotates one circle and the winding is completed. Because there is no tension, the steel strands are relatively loose. Since the outer layer of the steel strand has a large tension when in use, the steel strand will generate a large winding force on the inner layer of the steel strand, so that it will sink to the lower layer; or when the opening distance of the attached plate of the simple power-retractable steel strand device becomes too large due to the influence of the winding tension of the steel strand, the lateral gap between the steel strands is too large, which will also cause the outer layer of the steel strand to be embedded in the inner layer of the steel strand. Both situations will disrupt the order of the steel strand winding and also risk damaging the steel strand.

[0005] In order to prevent the strands from getting tangled between layers, a worker needs to stand next to the simple strand power take-up device to monitor during the work process. Once the possibility of tangled strands is found, some steel plates need to be placed manually to separate the strands. Since the tensile force and rigidity of the strands are very large, it is dangerous to stand next to the power take-up device, and the manually placed steel plates often deviate or cannot be fixed and fall off, affecting the winding quality of the strands. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the utility model provides a steel strand retracting and releasing system for automatically laying isolation plates, which can not only efficiently wind the steel strands, but also solve the problem of manually placing isolation steel plates, thereby reducing manpower input and improving the efficiency of steel strand retraction and release, thereby avoiding the problem of outer steel strands being embedded in inner steel strands and destroying the winding order of the steel strands.

[0007] The technical solution adopted by the utility model to solve the above-mentioned technical problem is: to provide a steel strand retracting and releasing system for automatically laying isolation plates, including a jack that provides lifting force to the steel strands, a wire arrangement device for arranging the steel strands output by the jack, and a steel strand power retracting and releasing body for pre-winding the steel strands arranged by the wire arrangement device;

[0008] The steel strand power retractable body has a rotatable first drum for winding the steel strand;

[0009] It also includes an interlayer isolation device for steel strands, which includes an isolation plate, which is released under the action of external force; the free end of the isolation plate is connected to the first drum, and as the first drum rotates, a structure of one layer of steel strands and one layer of isolation plate is formed.

[0010] Thereby, the purpose of simultaneously completing the winding of the steel strands and the automatic laying of the isolation plates is achieved as the first reel rotates, thereby improving the winding efficiency of the steel strands and the isolation effect of the isolation plates.

[0011] According to the utility model, further, the steel strand power retractable body has two vertical plates arranged opposite to each other, and the first drum penetrates the two vertical plates and rotates relative to the two vertical plates, thereby supporting the first drum and fixing the height of the first drum.

[0012] According to the utility model, further, one end of the first reel is connected to a driving part for driving the first reel to rotate, so as to realize automatic rotation of the first reel and solve the problem that the non-powered retractable device rotates passively and uncontrollably.

[0013] According to the utility model, further, the steel strand interlayer isolation device includes a second support having two relative support plates, a second drum is arranged between the two support plates, the second drum rotates along its axial direction, and the isolation plate is wound around the outer periphery of the second drum.

[0014] According to the utility model, further, the isolation plate includes two steel wire ropes arranged in parallel, and a barrier is arranged between the two steel wire ropes.

[0015] According to the utility model, further, the baffle is made of hard metal material.

[0016] According to the utility model, further, the barriers are arranged at equal intervals along the length direction of the steel wire rope.

[0017] According to the utility model, further, a rotation driving part is connected to one side of the second reel to drive the second reel to rotate.

[0018] According to the utility model, further, the first drum rotates in the opposite direction relative to the winding direction of the steel strand to release the steel strand. The steel strand power retracting and releasing device is similar to a winch, which can not only actively wind and store the steel strand, but also be used as a winch to lower the steel strand. In some lifting operations, it is necessary to quickly lower the unloaded sling to the ground. If a steel strand jack is used for lowering, the steel strand lowering speed is slow. The steel strand power retracting and releasing body can realize the continuous lowering of the steel strand, and the speed is much faster than the lowering speed of the steel strand jack.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the steel strand jack is placed on one side of the rope arrangement device, and the steel strand passes through the steel strand jack from top to bottom and then enters the semicircular structure of the rope arrangement device, and the arrangement of the steel strand gradually changes from a circular arrangement to an "I"-shaped arrangement, and the steel strand coming out of the rope arrangement device is a plurality of steel strands arranged in a layer and then comes out from the other side of the rope arrangement device, and then goes down to the steel strand power retractable wire body placed on the other side of the rope arrangement device. At the same time, a steel strand interlayer isolation device is placed on the other side of the steel strand power retractable wire body, and the isolation plate sent out from the second drum of the isolation device is wound around the outer periphery of the first drum together with the steel strand. A layer of isolation plate is sandwiched between each layer of steel strands on the outer periphery of the first drum, so that the steel strand layers are separated, and even if the tension of the steel strand is large, the steel strands of the upper layer will not fall into the steel strands of the lower layer.

[0020] The steel strand power retractable wire body can retract, release and wind the steel strand well, and there is no need to pre-wind the steel strand under ideal conditions. It can also ensure that the steel strand is always retracted and released in an orderly manner during use, and will not damage the steel strand or other related parts.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0026] like Figure 1 and Figure 2 As shown, the utility model provides a steel strand retracting and releasing system for automatically laying isolation plates, including a jack 100 for providing lifting force to the steel strands, a wire arrangement device 200 for arranging the steel strands output by the jack 100, and a steel strand power retracting and releasing body 300 for pre-winding the steel strands arranged by the wire arrangement device 200. Among them, the jack 100 has a top surface 110 and a bottom surface 120 opposite to the top surface 110. The top surface 110 and the bottom surface 120 are both provided with openings (not shown in the figure) for steel strands to pass through and out. There are multiple openings distributed along the corresponding surface circumference. Multiple steel strands can be lifted at one time. The steel strands pass through the openings of the bottom surface 120 and pass through the openings of the top surface 110 to form bundles of steel strands. In order to facilitate the winding and storage of bundles of steel strands, the bundles of steel strands need to be arranged through a wire arrangement device 200. The wire arrangement device 200 is arc-shaped, with an opening facing the ground, and has an inlet end 210 for the steel strands to enter and an outlet end 220 for the steel strands to output. The steel strands output from the outlet end 220 are arranged in a "one" shape from the bundles of steel strands, which is convenient for subsequent winding and storage. The steel strand power retracting and releasing body 300 is used to wind the steel strands output from the wire arrangement device. It is explained here that the jack 100 and the cable arrangement device 200 are both prior arts and will not be described in detail here.

[0027] The steel strand power retracting body 300 includes a first support, the first support has two vertical plates 310 arranged opposite to each other, a first drum 320 passes through the two vertical plates 310, and one end of the first drum 320 is connected to a driving part (not shown) for driving the first drum 320 to rotate. It is explained here that the driving part can be a component such as an electric motor that can drive the first drum 320 to rotate.

[0028] The driving unit connected to the first drum 320 applies torque to the steel strands for winding. As the first drum 320 rotates, the steel strands output from the outlet 220 of the cable arrangement device 200 are wound around the outer periphery of the first drum 320. When the first drum 320 rotates one circle, the steel strands are wound one layer.

[0029] The directions from the outer circumference close to the first drum 320 to the outer circumference far away from the first drum 320 are named as inner layer steel strands and outer layer steel strands.

[0030] In this embodiment, the relative inner surfaces of the two vertical plates 310 are further provided with an auxiliary plate 330, which is used to limit the axial movement of the steel strands wound around the outer periphery of the first drum 320, so that the steel strands are wound regularly and the two opposite end faces in the axial direction are flat. According to the number of steel strands in a row, a pad can be added between the auxiliary plate 330 and the first drum 320 to adjust the spacing between the left and right auxiliary plates 330 to adapt to different numbers of steel strands. When the number of steel strands is large, the pad is reduced, and when the number of steel strands is small, the pad is increased. The number and thickness of the pad are determined by the number of steel strands. For example, when a row of 10 steel strands is used, a pad is added between the two auxiliary plates 330 to adjust the spacing to 180 mm; when a row of 20 steel strands is used, the pad is reduced between the two auxiliary plates 330 to adjust the spacing to 360 mm. The number of pads is increased or decreased, and the steel strands do not move along the axial direction around the outer periphery of the first drum 320.

[0031] In order to solve the collapse problem between the inner layer and the outer layer of steel strands, as shown in Figure 2, a steel strand interlayer isolation device 400 is also provided, including a second support having two relative support plates 410, a second reel 420 is provided between the two support plates 410, the second reel 420 rotates along its axial direction, and an isolation plate is wound around the outer circumference of the second reel 420. The free end of the isolation plate is connected or abutted with the first reel 320, and as the first reel 320 rotates, a layered structure of a layer of steel strands and a layer of isolation plate is realized, which effectively isolates the adjacent inner and outer layers of steel strands, and prevents the outer layer of steel strands from collapsing toward the inner layer of steel strands. In addition, the isolation plate is automatically laid, which eliminates the problem of manual placement while ensuring that the position is fixed and there will be no deviation, thereby improving the isolation effect.

[0032] Specifically, the isolation plate includes two parallel steel wires 430, and a baffle 440 is arranged between the two steel wires 430. The baffle 440 is made of hard metal material to ensure that the rigidity can support the extrusion of the inner steel wire by the outer steel strands. Preferably, the baffle 440 is a rectangular steel plate, which is arranged at equal intervals along the length direction of the steel wires 430. In this way, during the automatic laying process, the support points can be evenly distributed, further improving the support effect.

[0033] In this embodiment, in order to improve the adjustability of the laying length of the isolation board, a reducer 450 and a servo motor 460 are sequentially connected to one side of the second reel 420. When the laying length of the isolation board or the slackness needs to be adjusted, the speed of the servo motor 460 can be adjusted to achieve the purpose of adjustment.

[0034] The steel strand winding process is as described above and will not be elaborated on again; when the steel strand needs to be released, there is no need to use the jack 100 to release it little by little. It is only necessary to drive the first reel 320 to rotate in the opposite direction of its winding process, so as to quickly release the steel strand and increase the release speed.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
