Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting auxiliary tools, in particular to an auxiliary protection device for hoisting heavy objects with a steel wire rope. Background Art

[0002] When using wire rope for hoisting operations such as various steel cable reels and conductor reels, the wire rope is in direct contact with the edges of the hoisted objects due to the large mass of the hoisted objects and the edges of the contact surface with the wire rope. The wire rope is subjected to large and concentrated tension, and repeated friction can not only easily deform the wire rope, but also cause strand breakage. In addition, the wire rope is prone to slipping during the rise and fall and rotation of objects in the air, posing a great safety risk.

[0003] Generally, when lifting heavy objects with edges and corners, such as steel cable reels and conductor reels, most of the lifting operations are performed by directly contacting the wire rope with the edges and corners of the lifting parts. Even if the contact between the wire rope and the lifting parts is covered with flexible materials, the bending radius of the wire rope is easy to form a dead bend, which does not meet the requirements of the lifting operation specifications.

[0004] The Chinese patent application number: 201520143156.5 discloses a counterweight hoisting auxiliary device, including a metal plate processed into a 90° bend, a rubber plate fixed on the metal plate, and a semicircular metal pipe sheet processed into a 90° bend. The metal plate can resist the damage of the sharp edge of the counterweight to the wire rope, and the damage of the wire rope to the counterweight, but because the metal plate is wide, it is easy to cause damage to the heavy objects with circular cross-sections such as various cable drums or pipes when hoisting them, and it is easy to shake during the hoisting process, so it is not suitable for hoisting operations of various common heavy objects such as various steel cable drums. Summary of the invention

[0005] In order to solve the deficiencies in the above-mentioned prior art, the inventors have developed and designed an auxiliary protection device for lifting heavy objects with wire rope, which can effectively solve the problems of wear and tear of wire ropes and slings, extend the service life of wire ropes and slings, greatly increase the reliability of lifting operations, and ensure the safety of lifting operations.

[0006] The technical solution adopted by the utility model is:

[0007] An auxiliary protection device for hoisting heavy objects with a steel wire rope, comprising:

[0008] The main body is an integrally formed L-shaped bending piece, the bending piece is bent inwardly toward the outside, presenting a half-section pipe-like structure, having an outward mounting groove, and a U-shaped or C-shaped cross-sectional shape;

[0009] The protective member is installed at the notch of the installation slot of the main member, and can block the opening edge of the notch. The lifting rope can pass between the protective member and the notch to prevent the passed lifting rope from slipping out of the installation slot;

[0010] The anti-slip pad is a sheet-like object made of a flexible material, which is adapted and fitted to the inner and outer surfaces of the main body and is used to provide buffering protection for the suspended object, the suspension rope and the main body.

[0011] Furthermore, the protective member is a semicircular arc-shaped locking member, one end of which is hingedly mounted on one side of the main body installation slot, and the other end can be locked or opened with the other side of the installation slot through a locking structure.

[0012] Furthermore, the protective member is in the form of a hook structure, the hook groove of the hook faces the installation groove on the main body, and a notch is provided on one side of the hook, while the other side is fixedly mounted on the side of the main body. There are at least two protective members with the hook structure, which are simultaneously mounted on both ends of the main body, and the notch opening directions of the two adjacent protective members are opposite.

[0013] Furthermore, the width of the installation groove is not less than the thickness of the suspension rope.

[0014] Furthermore, an arc-shaped pad is installed on the back of one of the bent pieces of the main body, and the outer curvature of the arc-shaped pad is adapted to the curvature corresponding to the radius of the pipe to be hoisted, and is used to pad the edge of the pipe to be hoisted, and the inner curvature of the arc-shaped pad is consistent with the curvature of the back of the main body; the arc-shaped pad is passed through and connected and fixed on the back of the main body by two pins.

[0015] Furthermore, a clamping nut is installed on the back of another bent piece of the main body, and a clamping screw is installed in the clamping nut. The clamping screw can be raised and lowered by turning the knob in the vertical direction. After being lowered, it can clamp the pipe component to be hoisted, so as to keep the main body in a stable installation state relative to the pipe component.

[0016] The working principle of this utility model is introduced as follows:

[0017] The auxiliary protection device for lifting heavy objects with steel wire rope of the utility model aims to solve the problem that during the lifting of heavy objects (such as steel cable drums, conductor drums, pipes, etc.), the steel wire rope is subjected to large and concentrated tension due to point contact between the object being lifted and the steel wire rope, and the steel wire rope may break and slip due to repeated friction during multiple lifting operations. The main body of the utility model is an integrally formed L-shaped bending piece, which forms a half-section pipe-like structure with an installation groove on it, so that the lifting rope can be easily embedded therein for limiting and protecting the lifting rope so that it does not have point contact with the object being lifted; the protective part is installed on the installation groove of the main part, which can block the opening edge of the groove, thereby preventing the lifting rope from slipping out of the installation groove during the lifting process; the anti-slip pad part is a sheet of flexible material attached to the inner and outer surfaces of the main part, which is used to buffer the friction between the object being lifted, the lifting rope and the main part, and prevent the direct friction from causing damage to the contact point of the object being lifted. At the same time, since the overall design also includes a blocking device, a hook structure, a trough with appropriate width, an arc-shaped pad and a clamping device, the overall structure is more reasonable, which can further protect the lifting rope, improve the stability and safety of the lifting process, and thus greatly enhance the reliability of the lifting operation.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] (1) It can avoid the direct contact between the wire rope and the corners of the hoisted object, and can prevent the wire rope from forming a dead bend at the corners, which can greatly extend the service life of the wire rope and ensure the safety of the hoisting operation;

[0020] (2) One end of the protective piece is fixedly connected to the semicircular tube segment, and the other end is open. There shall be no less than two protective pieces on the semicircular tube segment, and the openings are arranged in a cross direction, which is convenient for putting on and removing the wire rope and can limit the wire rope to prevent it from slipping;

[0021] (3) An anti-skid pad is arranged inside the arc-shaped piece to reduce the friction between the wire rope and the device, and the wear of the wire rope; an anti-skid pad is arranged outside the arc-shaped piece to reduce the friction between the suspended object and the device, and the wear of the suspended object, as well as the slipping of the suspended object and the device during the lifting process; thus, the stability during the lifting process is ensured and the risk caused by shaking during the lifting process is reduced.

[0022] (4) Wide range of applications. The equipment is suitable for hoisting heavy objects with circular cross-sections such as various cable drums or pipes. This technical solution makes hoisting operations more efficient because it avoids frequent replacement of wire ropes due to wire rope wear, saving time and cost for wire rope replacement.

[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0031] like Figure 1-6 As shown, an auxiliary protection device for hoisting heavy objects with a steel wire rope comprises:

[0032] The main body 1 is an integrally formed L-shaped bending piece, which is bent inwardly to the outside and presents a half-section pipe-like structure, with an outward-facing installation groove 11, and a U-shaped or C-shaped cross-sectional shape; the protective member 12 is installed at the notch of the installation groove 11 of the main body 1, and can form a blockage on the opening edge of the notch. The lifting rope 2 can pass between the protective member 12 and the notch, which is used to prevent the passing lifting rope 2 from slipping out of the installation groove 11; the anti-slip pad 13 is a sheet-like object made of flexible material, which is adapted and fitted to the inner and outer surfaces of the main body 1, and is used to provide buffering protection for the suspended object, the lifting rope 2 and the main body 1.

[0033] When in use, the lifting rope 2 passes through the heavy object to be lifted. In this embodiment, a pipe is taken as an example. The lifting rope 2 passes through both ends of the pipe. At the contact point between the lifting rope 2 and the upper wall of the pipe, the auxiliary protection device for lifting heavy objects with a steel wire rope is used. One end of the main part 1 of the L-shaped bending piece is inserted into the edge of the pipe, and the other end is upwardly located on the outside of the edge of the pipe. The lifting rope 2 passes through the protective part 12 and is embedded in the installation groove 11, so that the main part 1 is located between the contact point between the lifting rope 2 and the pipe, and the protective part 12 is locked so that the lifting rope 2 will not fall out of the L-shaped bending piece. Then, a lifting force can be applied, and the main part 1 plays a role in buffering and protecting the lifting rope 2.

[0034] Preferably, the protective member 12 is a semicircular arc-shaped locking member 14, one end of which is hingedly mounted on one side of the mounting groove 11 of the main member 1, and the other end can be locked or unlocked with the other side of the mounting groove 11 through a locking structure. A conventional lock is installed at one end of the locking member 14, and cooperates with a locking ear provided on a corresponding part of the main member 1 to lock the notch of the mounting groove 11, so that the sling 2 will not slip out of it;

[0035] In another way, the protective member 12 is a hook structure, the hook groove of the hook faces the installation groove 11 on the main body 1, and a notch 15 is opened on one side of the hook, and the other side is fixedly installed on the side of the main body 1. There are at least two protective members 12 of the hook structure, which are installed on both ends of the main body 1 at the same time, and the opening directions of the notches 15 of the two adjacent protective members 12 are opposite. When in use, the hanging rope 2 is manually wound through the notch 15 into the installation groove 11 to achieve installation. Since the notches 15 are in opposite directions, the hanging rope 2 has a very low probability of sliding out of the two notches 15 at the same time, thereby forming a lock body structure. This structure does not require manual buckling, and does not require additional lock installation. It can be quickly fixedly installed with the main body 1 through welding;

[0036] Preferably, an arc-shaped pad 16 is installed on the back of one of the bent pieces of the main body 1, and the outer curvature of the arc-shaped pad 16 is adapted to the curvature corresponding to the radius of the pipe to be hoisted, and is used to pad the edge of the pipe to be hoisted, and the inner curvature of the arc-shaped pad 16 is consistent with the curvature of the back of the main body 1; the arc-shaped pad 16 is passed through and connected and fixed on the back of the main body 1 by two pins 17. The arc-shaped pad 16 is designed according to the shape of the hoisted object, and can more closely adapt to the shape of the hoisted object, such as round, arc, etc., to ensure the stability of the hoisting process; the arc-shaped pad 16 can play a protective role, preventing friction or impact during the hoisting process from directly acting on the objects to be hoisted, thereby avoiding damage to the objects; the shape of the arc-shaped pad 16 can help to hoist heavy objects more stably, grasp the balance point of the object, and prevent slipping or shaking during the hoisting process; due to its special shape, the arc-shaped pad 16 can disperse the pressure acting on the hoisted objects during the hoisting process, ensure a smoother hoisting process, and reduce the possibility of deformation of the objects.

[0037] Preferably, a clamping nut 18 is installed on the back of another bent piece of the main body 1, and a clamping screw 19 is installed in the clamping nut 18. The clamping screw 19 can be raised and lowered by turning the knob in the vertical direction. After being lowered, it can clamp the pipe part to be hoisted, so as to keep the main body 1 in a stable installation state relative to the pipe part. Such a design can be installed on the upper wall edge of the pipe before hoisting. After the clamping screw 19 is unscrewed, an elastic gasket structure is installed on the lower end of the clamping screw 19, which contacts the outer wall of the pipe and clamps the pipe, so that the device can be installed on the pipe mouth without holding it by hand, which is convenient for manual operations such as threading the lifting rope 2, and improves work efficiency and convenience.
