Description

Technical Field

[0001] The invention relates to the technical field of steel cord production, in particular to a quick transport tool and a transport method for an I-shaped wheel. Background Art

[0002] In the process of steel cord production, in order to meet its winding requirements, I-shaped wheels are usually used as the winding structure of steel cord. In the steel cord production and processing workshop, I-shaped wheels often need to be circulated in different steel cord processing procedures. Especially after the steel cord is produced, the I-shaped wheels with full wires will be continuously transported along the conveying device. During this process, the I-shaped wheels need to be extracted and the steel cord wound by the I-shaped wheels needs to be tested for various indicators. More than a dozen wheels need to be tested at the same time, such as appearance quality inspection, dimensional performance inspection, process performance inspection, mechanical performance inspection, etc.

[0003] During the current inspection process, manual handling is required every time, which greatly increases the workload of operators. If a crane is used in conjunction with wire rope binding, the speed is too slow and cannot meet the needs of fast and flexible transfer. Summary of the invention

[0005] A first clamping arm, a first end of which is provided with a lifting ring, the lifting ring being connected to the overhead crane system, and a second end of which is provided with a first engaging structure;

[0006] A second clamping arm, a first end of which is provided with a second engaging structure, and a second end of which is provided with a supporting structure, wherein the supporting structure is used to contact the surface of the steel wire wound on the spool;

[0007] a handle connected to the second end of the first clamping arm;

[0008] Wherein, the first clamping arm and the second clamping arm are hingedly connected, and the first clamping arm can rotate relative to the second clamping arm within a certain range;

[0009] The opening of the first biting structure is toward the first end of the first clamping arm, and the opening of the second biting structure is toward the second end of the second clamping arm. A biting groove is formed between the first biting structure and the second biting structure, and the biting groove is used to clamp the wheel surface edge of the I-shaped wheel;

[0010] The angle between the first clamping arm and the second clamping arm is an obtuse angle. When the angle between the first clamping arm and the second clamping arm becomes smaller, the width of the bite groove increases, so that the edge of the wheel surface can enter the bite groove. When the angle between the first clamping arm and the second clamping arm becomes larger, the width of the bite groove decreases, so that the edge of the wheel surface is in the bite groove.

[0011] Preferably, the first biting structure forms a first opening toward the direction of the first clamping arm, and the second biting structure forms a second opening toward the direction of the second clamping arm. The first opening and the second opening are both constructed to gradually increase in width toward the opening direction, and the first opening and the second opening together form a biting groove.

[0012] Preferably, the engaging groove is constructed such that the width of the groove bottom is greater than the width of the groove opening, and when the angle between the first clamping arm and the second clamping arm changes, the width change rate of the groove opening is greater than the width change rate of the groove bottom.

[0013] Preferably, the second end of the first clamping arm is provided with a first connecting portion, the first end of the second clamping arm is provided with a second connecting portion, the first connecting portion is provided with a first axial hole, the second connecting portion is provided with a second axial hole, the first clamping arm and the second clamping arm are connected by bolts, the bolts pass through the first axial hole and the second axial hole, the first axial hole is closer to the second end of the first clamping arm than the first bite structure, and the second axial hole is closer to the first end of the second clamping arm than the second bite structure.

[0014] Preferably, the first connecting portion is further provided with a positioning hole, and the handle is fixed to the first clamping arm by a fastening screw connected to the positioning hole. The handle is located on one side of the second clamping arm, so that the second clamping arm can only rotate relative to the first clamping arm within a predetermined range.

[0015] Preferably, the first clamping arm is provided with a slot, so that the first connecting portion and the first engaging structure of the first clamping arm are constructed as two parts located on both sides of the slot, and the second clamping arm is inserted into the slot.

[0016] Preferably, an inner wall of the second engaging structure is provided with an arc-shaped groove, and the arc-shaped groove matches the arc-shaped wall surface of the edge of the wheel surface.

[0017] Preferably, the support structure is constructed to have an arc surface that fits the full wheel surface of the I-shaped wheel, and a protective layer is provided on the contact surface between the support structure and the I-shaped wheel.

[0018] Preferably, when the wheel surface edge is in the bite groove and the lifting ring is pulled upward, the slot width of the bite groove decreases until the first bite structure contacts the lower wall surface of the wheel surface edge, and the area where the first bite structure contacts the wheel surface edge is a plane.

[0019] The second aspect of the present invention provides a technical solution, a method for quickly transporting an I-shaped wheel, using the above-mentioned quick transport tool for the I-shaped wheel, comprising the following steps:

[0020] Step 1, hold the handle and lift it upward until the first clamping arm and the second clamping arm are at the smallest angle;

[0021] Step 2, move the tool in a nearly horizontal direction so that the edge of the wheel surface of the I-shaped wheel enters the opening of the bite groove, and the supporting structure touches the steel wire surface of the I-shaped wheel;

[0022] Step 3, press the handle downward to make the first clamping arm and the second clamping arm be at the maximum angle, and the I-shaped wheel is clamped;

[0023] Step 4: Use the overhead crane to transfer the I-shaped wheel to the target area. When the bottom of the I-shaped wheel touches the target area, lift the handle upwards so that the first clamping arm and the second clamping arm are at the smallest angle, and pull it outwards in a nearly horizontal direction to disengage the edge of the wheel surface from the engagement groove, thus completing the transportation of the I-shaped wheel.

[0024] Compared with the prior art, the advantages of the present invention are:

[0025] The handling tool proposed in the present application has a simple structure and only includes two relatively movable structures, namely a first support arm and a second support arm. A variable width engagement groove is formed between the first support arm and the second support arm, and a stable clamping structure is formed by clamping the edge of the I-shaped wheel and supporting the wheel surface of the I-shaped wheel. At the same time, the handle can flexibly control the state of the two support arms, and can flexibly and conveniently realize the loading, lifting posture control and unloading of the I-shaped wheel, thereby meeting the needs of short-distance and frequent handling of vertical I-shaped wheels in the joint workshop.

[0037] In order to better understand the technical content of the present invention, specific embodiments are given and described as follows in conjunction with the accompanying drawings.

[0038] It should be understood that in the steel cord twisting production workshop, especially after the steel wire is twisted, it needs to go through multiple inspection processes. Therefore, the full wheel of I-shaped pulleys needs to be transferred from the conveying device on one side (such as a transfer vehicle or conveyor belt, etc.) to the testing equipment on one side. Due to the large number of inspection items, not only the number of transports is large, but also the transport is required to be as fast as possible. At the same time, due to the close distance between the conveying device and the testing equipment, the current overhead crane combined with the wire rope binding method is too slow to meet the requirements, and the manual transportation is too labor-intensive. Therefore, both cannot meet the needs.

[0039] Based on the above, the present application aims to propose a tool for quickly transferring an I-shaped wheel from a conveying device to a detection device. Since the I-shaped wheel is usually more stable in a vertical position in the conveying device, this handling tool is used to carry the I-shaped wheel in a vertical state. The I-shaped wheel in a vertical state can use the upper wheel surface as an anchor point to establish a connection relationship between the handling tool and the I-shaped wheel. The currently commonly used solution of clamping the I-shaped wheel from the outer edge of the I-shaped wheel has poor stability and flexibility.

[0040] Therefore, the handling tool proposed in this application is intended to clamp the rim of the I-shaped wheel on one side and support the wound wire surface at the same time, so that the I-shaped wheel can reach a stable state, and can quickly and flexibly complete the clamping-transferring-unloading actions of the I-shaped wheel.

[0041] [Quick handling tool for I-shaped wheels]

[0042] Combination Figure 1 As shown, the first aspect of the present invention proposes a quick handling tool for an I-shaped wheel, which mainly includes a first clamping arm 10, a second clamping arm 20 and a handle 30. The first clamping arm 10 and the second clamping arm 20 are cross-arranged, and the handle 30 is fixed to the first clamping arm 10 to control the angle and posture of the first clamping arm 10. The loading and unloading of the entire I-shaped wheel can be completed by operating the handle 30 with one hand, which is very flexible.

[0043] Specifically, a lifting ring 11 is provided at the first end of the first clamping arm 10, and the lifting ring 11 is connected to the overhead crane system. A first engaging structure 13 is provided at the second end of the first clamping arm 10, a second engaging structure 22 is provided at the first end of the second clamping arm 20, and a supporting structure 23 is provided at the second end of the second clamping arm 20, and the supporting structure 23 is used to contact the surface of the steel wire wound on the I-shaped wheel.

[0044] The lifting ring 11 preferably extends to above the center of the spool to ensure that the posture of the spool can be easily controlled during lifting.

[0045] Furthermore, the handle 30 is connected to the second end of the first clamping arm 10. Thus, the user can control the angle of the first clamping arm 10 relative to the second clamping arm 20 through the handle 30, and can also control the position and posture of the tool and the spool.

[0046] The first clamping arm 10 and the second clamping arm 20 are hingedly connected, and the first clamping arm 10 can rotate relative to the second clamping arm 20 within a certain range.

[0047] Combination Figures 1 to 4As shown, the opening of the first biting structure 13 is toward the first end of the first clamping arm 10, and the opening of the second biting structure 22 is toward the second end of the second clamping arm 20. A biting groove 40 is formed between the first biting structure 13 and the second biting structure 22, and the biting groove 40 is used to clamp the wheel surface edge 101 of the I-shaped wheel.

[0048] In this way, the engaging groove 40 is engaged with the wheel surface edge 101 of the I-shaped wheel 100, and the supporting structure 23 contacts the surface of the steel wire wrapped around the I-shaped wheel 100. When the lifting ring 11 is pulled upward, the first engaging structure 13 tends to move upward, and the supporting structure 23 contacts the surface of the steel wire, so that the second engaging structure 22 tends to move downward. Therefore, the engaging groove 40 formed between the first engaging structure 13 and the second engaging structure 22 can stably hold the wheel surface edge 101 to prevent the I-shaped wheel from falling off. The user only needs to hold the handle 30 to control the trajectory and posture of the I-shaped wheel during transportation.

[0049] Specifically, the user is in the aisle between the conveying device and the detection equipment, and uses a tool to move the I-shaped wheel from the first side of the aisle to the second side. During this process, the user bites the engagement groove 40 into the wheel surface edge 101 of the I-shaped wheel, and then rotates itself 180°, so that the I-shaped wheel can be moved from the conveying device to the detection equipment. The operation is quick and flexible.

[0050] Further, combined with Figure 5 As shown, since the angle between the upper wheel surface and the steel wire surface is 90°, and the edge of the wheel surface is farther away than the steel wire surface, the angle between the first clamping arm 10 and the second clamping arm 20 is an obtuse angle, so that the formed engaging groove 40 and the supporting structure 23 correspond to the positions of the wheel surface edge 101 and the steel wire surface respectively.

[0051] Combination Figure 3 and Figure 4 As shown, the support structure 23 is constructed to have an arc surface that fits the full wheel surface of the I-shaped wheel, and a protective layer 24 is provided on the contact surface between the support structure 23 and the I-shaped wheel.

[0052] Optionally, the supporting structure 23 is an arc-shaped plate structure, and the protective layer 24 is a rubber sleeve sleeved on the outer wall of the arc-shaped plate structure.

[0053] In this way, the support structure 23 provides a large-area support for the surface of the steel wire, and the rubber sleeve can prevent the steel wire from being scratched.

[0054] When the angle between the first clamping arm 10 and the second clamping arm 20 becomes smaller, the width of the bite groove 40 increases, so that the wheel surface edge 101 can enter the bite groove 40. When the angle between the first clamping arm 10 and the second clamping arm 20 becomes larger, the width of the bite groove 40 becomes smaller, so that the wheel surface edge 101 is in the bite groove 40.

[0055] like Figure 2 As shown, the first biting structure 13 forms a first opening 41 toward the direction of the first clamping arm 10, and the second biting structure 22 forms a second opening 42 toward the direction of the second clamping arm 20. The first opening 41 and the second opening 42 are both constructed to gradually increase in width toward the opening direction, and the first opening 41 and the second opening 42 together form a biting groove 40.

[0056] The meshing groove 40 thus formed has a large groove bottom width and a small groove opening width, and the width of the meshing groove 40 is easy to control and is compatible with the shape of the wheel surface edge 101 of the I-shaped wheel (the outer edge thickness of the wheel surface edge 101 is large and the inner edge thickness is small).

[0057] Furthermore, the biting groove 40 is constructed so that the width of the bottom of the groove is greater than the width of the groove opening. When the angle between the first clamping arm 10 and the second clamping arm 20 changes, the rate of change of the width of the groove opening is greater than the rate of change of the width of the bottom of the groove. Therefore, when it is necessary to insert the wheel surface edge 101, the width of the groove opening is increased so that the wheel surface edge 101 can enter the biting groove 40, and then the width of the groove opening is reduced so that the wheel surface edge 101 can be inserted into the biting groove 40.

[0058] Combination Figure 4 As shown, the second end of the first clamping arm 10 is provided with a first connecting portion 12, the first end of the second clamping arm 20 is provided with a second connecting portion 21, the first connecting portion 12 is provided with a first axial hole 121, the second connecting portion 21 is provided with a second axial hole 211, the first clamping arm 10 and the second clamping arm 20 are connected by a bolt 31, the bolt 31 passes through the first axial hole 121 and the second axial hole 211, the first axial hole 121 is closer to the second end of the first clamping arm 10 than the first bite structure 13, and the second axial hole 211 is closer to the first end of the second clamping arm 20 than the second bite structure 22.

[0059] In this way, when the first clamping arm 10 and the second clamping arm 20 rotate around the axis of the bolt 31, the bottom of the engaging groove 40 changes less, while the width of the groove becomes larger, and the width of the groove can be changed. The widened groove makes it easier for the wheel surface edge 101 to enter the engaging groove 40, and the reduced groove width prevents the wheel surface edge 101 in the engaging groove 40 from falling out.

[0060] It can be understood that the first clamping arm 10 and the second clamping arm 20 cannot continuously rotate relative to each other, otherwise the clamp will be in an unstable state. Furthermore, the first connecting part 12 is also provided with a positioning hole 122, and the handle 30 is fixed to the first clamping arm 10 by a fastening screw 32 connected to the positioning hole 122. The handle 30 is located on one side of the second clamping arm 20, so that the second clamping arm 20 can only rotate relative to the first clamping arm 10 within a predetermined range.

[0061] In this way, when the angle between the first clamping arm 10 and the second clamping arm 20 increases to a certain value, the second clamping arm 20 and the handle 30 abut against each other, so that the angle cannot continue to increase. Similarly, when the angle between the first clamping arm 10 and the second clamping arm 20 decreases to a certain value, the second clamping arm 20 and the handle 30 abut against each other, so that the angle cannot continue to decrease. Therefore, the tool can be kept in a stable state.

[0062] In a preferred embodiment, when the first clamping arm 10 and the second clamping arm 20 are at the largest angle, the width of the notch of the bite groove 40 corresponds to the thickness of the thinnest part of the wheel surface edge 101, so that the wheel surface edge 101 entering into the bite groove 40 will not slip out. When the first clamping arm and the second clamping arm 20 are at the smallest angle, the width of the notch of the bite groove 40 corresponds to the thickest thickness of the wheel surface edge 101, so that the wheel surface edge 101 can easily enter into the bite groove 40.

[0063] Combination Figure 5 , Figure 6 and Fig.10 As shown, when the wheel surface edge 101 is in the bite groove 40 and the lifting ring 11 is pulled upward, the slot width of the bite groove 40 decreases until the first bite structure 13 contacts the lower wall surface of the wheel surface edge 101, and the area where the first bite structure 13 contacts the wheel surface edge 101 is a plane.

[0064] In this way, when the lifting ring 11 is pulled upward, the angle between the first clamping arm 10 and the second clamping arm 20 tends to increase, so the width of the bite groove 40 is reduced, so that the wheel surface edge 101 is compressed. Designing the area where the first bite structure 13 contacts the wheel surface edge 101 as a plane can reduce the pressure on the wheel surface edge 101 and avoid deformation of the wheel surface edge 101.

[0065] Combination Figure 2 As shown, the first clamping arm 10 is provided with a slot 14 , and the second clamping arm 20 is inserted into the slot 14 .

[0066] It can be understood that the first clamping arm 10 is a block structure set to a predetermined cross-sectional shape, and the slot 14 makes the first connecting part 12 and the first engaging structure 13 of the first clamping arm 10 be constructed as two parts on both sides of the slot 14, wherein the two parts separated by the slot 14 have the same thickness, and the second clamping arm 20 has the same thickness as the width of the slot 14 and is just located in the slot 14 of the first clamping arm 10.

[0067] So, combined Figure 3As shown, there are two first bite structures 13 and one second bite structure 22. The two first bite structures 13 and one second bite structure 22 are distributed in a triangle. The two first bite structures 13 contact the lower wall surface of the wheel surface edge 101, and the second bite structure 22 contacts the upper wall surface of the wheel surface edge 101.

[0068] Combination Figure 6 and Figure 7 As shown, the inner wall of the second engaging structure 22 is provided with an arc-shaped groove 421 , and the arc-shaped groove 421 matches the arc-shaped wall surface of the wheel surface edge 101 .

[0069] In this way, it can be ensured that when the engaging groove 40 clamps the wheel surface edge 101, the wheel surface edge 101 and the engaging groove 40 remain fixed in the horizontal direction without displacement, and the clamping between the first clamping arm 10 and the second clamping arm 20 can keep the wheel surface edge 101 and the engaging groove 40 fixed in the vertical direction without displacement.

[0070] [Quick transportation method of I-shaped wheels]

[0071] The second aspect of the present invention provides a technical solution, a method for quickly transporting an I-shaped wheel, using the above-mentioned quick transport tool for the I-shaped wheel, comprising the following steps:

[0072] Step 1: Combine Figure 8 As shown, hold the handle 30 and lift the handle 30 upward until the first clamping arm 10 and the second clamping arm 20 are at the smallest angle;

[0073] Step 2: Combine Figure 8 As shown, the tool is moved in a nearly horizontal direction so that the wheel surface edge 101 of the spool enters the opening of the engaging groove 40, and the supporting structure 23 touches the steel wire surface of the spool;

[0074] Step 3: Combine Fig. 9 and Fig.10 As shown, the handle 30 is pressed downward to make the first clamping arm 10 and the second clamping arm 20 in a state of maximum included angle, at which time the I-shaped wheel is clamped;

[0075] Step 4, transfer the I-shaped wheel to the target area by means of a crane. When the bottom of the I-shaped wheel contacts the target area, lift the handle 30 upwards so that the first clamping arm 10 and the second clamping arm 20 are at the smallest angle, and pull them outwards in a nearly horizontal direction so that the edge 101 of the wheel surface is disengaged from the engaging groove 40, thus completing the transport of the I-shaped wheel.

[0076] During the upward lifting and hoisting process, the specific force analysis is as follows: the overhead crane lifts the hook upward, the hook lifts the lifting ring, and drives the first clamping arm 10 to lift upward, and the handle 30 always maintains a thrust to the wheel edge 101 of the I-shaped wheel, so that the first opening 41 of the first clamping arm 10 is always close to the wheel edge 101 of the I-shaped wheel. In the process of lifting the first clamping arm 10, the I-shaped wheel will have a tendency to fall to the left. At this time, the steel wire on the I-shaped wheel will generate an outward thrust on the second clamping arm 20, and the second clamping arm 20 will rotate outward through the rotation point. At this time, the second opening 42 of the second clamping arm 20 will firmly bite the wheel edge 101 of the I-shaped wheel, and the I-shaped wheel is firmly locked through the upper and lower coordinated bites and the support point (support structure 23) that prevents the I-shaped wheel from tipping over.

[0077] In combination with the above embodiments, the handling tool proposed in the present application has a simple structure and only includes two relatively movable structures, namely a first support arm and a second support arm. Through the variable width engagement groove formed between the first support arm and the second support arm, the edge of the I-shaped wheel can be clamped to form a first support point. At the same time, a support structure is provided under the second support wall to support the steel wire surface of the wheel surface of the I-shaped wheel to form a second support point. Through two support points, a lifting point (a lifting ring at the upper end of the first support arm) and a control point (a handle at the lower end of the first support arm), the loading, lifting posture control and unloading of the I-shaped wheel can be realized. It is quite flexible and reliable, and can meet the needs of short-distance and frequent vertical I-shaped wheel handling in the jointing workshop.

[0078] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention.
