Description

Technical Field

[0001] The present invention belongs to the technical field of hoisting, and specifically relates to a device for protecting steel wire ropes during hoisting. Background Art

[0002] Currently, during equipment hoisting, when a steel wire rope directly contacts the edge of the equipment pipe diameter, the protruding pipe orifice edge, the insulation support ring edge, etc., in order to prevent the steel wire rope from being worn or even broken, construction workers usually temporarily find several wooden sleepers in the nearby working area and place them between the steel wire rope and the sharp edge or surface of the equipment to avoid direct contact between the two. However, since the wooden sleepers are fixed only by the radial component of the tension force on the steel wire rope, and the steel wire rope is always in a moving state during hoisting, especially during the flipping of the equipment head, when the force on the steel wire rope becomes smaller and gradually relaxes, the wooden sleepers cannot be fixed all the time and may slip at any time, which has a certain degree of danger; moreover, the length and thickness of the wooden sleepers need to match the area where the steel wire rope contacts the equipment during this hoisting. Improper selection will have a certain impact on the protection effect, and it is time-consuming and laborious to find suitable wooden sleepers; the used wooden sleepers are usually discarded randomly, which is neither economical nor environmentally friendly.

[0003] For example, in equipment hoisting operations, if the selected wooden sleeper specifications are too small, the steel wire rope will directly contact the top edge of the equipment, causing certain damage to the steel wire rope, and when unhooking at height, the wooden sleeper will fall from a high place, posing a safety hazard. Another example is in the operation of flipping the equipment head. As the head is forced to flip, the steel wire rope will slide along the large diameter edge of the head to both sides, and the supported wooden sleepers or iron sheets cannot synchronize, resulting in the steel wire rope still directly contacting the edge of the pipe diameter with a certain sharpness. Summary of the Invention

[0004] The present invention focuses on solving the technical problem of how to effectively protect the steel wire rope during hoisting, and proposes a detachable combined fixture for protecting the steel wire rope, which can be directly fixed to the steel wire rope during hoisting and has a reliable connection, thereby effectively avoiding direct contact between the steel wire rope and the sharp edge or surface of the equipment. At the same time, the fixture can be assembled and disassembled to match the length change of the steel wire rope in different contact areas. In addition, each section of the fixture can be reused, ensuring the safety of the hoisting tackle while achieving the effects of economy and environmental protection.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] A detachable combined fixture for protecting a wire rope, which is composed of a single fixture unit or composed of several fixture units connected in series in sequence. Each of the fixture units includes two symmetrically arranged components; each of the components is a block structure, and its top surface is an arc surface that gradually decreases from the outside to the inside; a row of magnet blocks is embedded in the top surface of each of the components, and the top surface of the magnet blocks is flush with the arc top surface of the components; the magnet blocks are used to adsorb and fix the components on the wire rope.

[0007] In each of the fixture units, a row of upright post holes is respectively arranged on the opposite surfaces of the paired components, and a connecting post is arranged inside each of the upright post holes; between the paired components in each of the fixture units, the paired components are connected to each other by several connecting springs, and two ends of each connecting spring are respectively connected to the connecting posts at opposite positions of the paired components; after the paired components in each of the fixture units are symmetrically arranged and connected by several connecting springs, the top surfaces of the paired components form a telescopic arc surface as the acting surface of the wire rope.

[0008] At both ends of the paired components in each of the fixture units, a T-shaped slider and a T-shaped chute are respectively arranged, the T-shaped slider and the T-shaped chute are matched, and the T-shaped slider can freely slide along the end surface of the component in the T-shaped chute; the increase in the length of the detachable combined fixture is realized by the connection of the T-shaped sliders and the T-shaped chutes of adjacent fixture units.

[0009] Further, the change in the bending degree of the detachable combined fixture is realized by the connection between adjacent fixture units by a connecting piece, a bolt and a nut. Both ends of the connecting piece are respectively hinged to the adjacent components on the same side of the adjacent fixture units by bolts and nuts.

[0010] Furthermore, at one end of each component close to the T-shaped slider, a stepped hole penetrating the component is arranged. The stepped hole is composed of a round hole section on the outside and a square hole section on the inside. The radial dimension of the square hole section is larger than that of the round hole section and a step surface is formed at the junction of the two. The round hole section is used to accommodate the optical axis of the bolt rod, and the square hole section is used to accommodate the nut.

[0011] On both sides of adjacent fixture units, a set of the connecting piece, the bolt and the nut are respectively arranged; both ends of the connecting piece are respectively provided with round holes; the middle section of the bolt is an optical axis, one end of the optical axis is a bolt head and the other end is a thread; the bolt sequentially passes through the round holes of the connecting piece and the round hole section and the square hole section of the stepped hole of the component, and is tightly connected to the nut by its thread in the square hole section, and the step surface of the component limits the nut.

[0012] Further, the magnet blocks are evenly arranged at equal intervals along the length direction of the component and are centered in the width direction of the component.

[0013] Further, the connecting columns are evenly arranged at equal intervals along the length direction of the component.

[0014] Further, the T-shaped slider is integrally formed with or detachably connected to the component.

[0015] The beneficial effects of the present invention are as follows:

[0016] (1) The detachable combined fixture for protecting the steel wire rope of the present invention can effectively avoid the direct contact between the steel wire rope and the sharp edges or sharp contact surfaces of the equipment, has a good protective effect on the steel wire rope, improves the service life of the steel wire rope, and has high economy.

Specific embodiments

[0031] To further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings:

[0032] This embodiment provides a detachable combined fixture for protecting a steel wire rope, which is composed of a single fixture unit 1 or composed of several fixture units 1 connected in series in sequence, as Figure 1 shown, each fixture unit 1 includes two symmetrically arranged components 101.

[0033] Such as Figures 2 to 5As shown, each component 101 is a block structure similar to a cuboid. Its top surface is an arc surface that gradually decreases from the outside to the inside. Its front, rear, and bottom surfaces are all rectangles, and its two end surfaces are trapezoids with arc-shaped hypotenuses. A row of mounting holes 102 is provided on the top surface of the component 101. The mounting holes 102 are triangular prism-shaped. A number of mounting holes 102 are evenly arranged at equal intervals along the length direction of the component 101 and are centered in the width direction of the component 101. A magnet block 103 is provided in each mounting hole 102. The magnet block 103 is embedded in the component 101 and its top surface is flush with the arc top surface of the component 101. The bottom surface of the magnet block 103 can be fixedly attached to the component 101. T-shaped sliders 104 and T-shaped chutes 105 are respectively provided at both ends of the component 101. The longitudinal section of the T-shaped slider 104 is trapezoidal; the T-shaped slider 104 and the T-shaped chute 105 cooperate with each other for the serial connection of the component 101 and the component 101 in the length direction. A row of column holes 106 is provided on the opposite surfaces of the two components 101 in each fixture unit 1. A number of column holes 106 are evenly arranged at equal intervals along the length direction of the component 101. A cylindrical connecting column 107 is provided inside each column hole 106. The connecting columns 107 at opposite positions in the two components 101 are respectively used to fixedly connect the bent rings at both ends of the spring 2. The component 101 is provided with a stepped hole 108 at one end close to the T-shaped slider 104. The stepped hole 108 is composed of a circular hole section on the outside and a square hole section on the inside. The radial dimension of the square hole section is larger than that of the circular hole section and a stepped surface is formed at the junction of the two. The circular hole section is used to accommodate the optical axis of the bolt rod, and the square hole section is used to accommodate the nut to prevent the nut from protruding from the component 101 and to prevent interference when the two opposite components 101 are fitted together.

[0034] Each fixture unit 1 includes two symmetrically arranged components 101. One end of each of the two paired components 101 is a T-shaped slider 104, and the other end is a T-shaped chute 105. The two paired components 101 are connected to each other by a number of connecting springs 2. As Figure 6 shown, bent rings are respectively provided at both ends of the connecting spring 2. The bent rings at both ends of each connecting spring 2 are respectively installed on the connecting columns 107 at opposite positions of the two paired components 101. As Figure 7 shown, after the two paired components 101 of the fixture unit 1 are oppositely arranged and connected by a number of connecting springs 2, the top surfaces of the two paired components 101 form a retractable complete fixture arc surface as the acting surface of the wire rope 3. The contact clamping between the fixture arc surface of the two paired components 101 of the fixture unit 1 and the wire rope 3 is realized by the adsorption action of the magnet blocks 103 embedded in each component 101. The displacement amount of the connecting spring 2 itself and the selection of connecting springs 2 with different specifications and lengths can realize the protection of wire ropes 3 with different specifications and diameters. When the width of the contact area of the wire rope 3 is relatively narrow, the connecting spring 2 can also not be used, and the fitting with the wire rope 3 is realized only by the adsorption action of the magnet blocks 103 embedded in the component 101.

[0035] As Figures 8 to 10 shown, the fixture unit 1 is combined or used singly according to the specification of the wire rope 3 selected for each hoisting and the specific situation of contact with the edge of the equipment. When the length of the wire rope 3 to be protected is relatively long, a combined working surface can be formed by connecting several fixture units 1 in series. The connection between the fixture units 1 is realized by the cooperation of the T-shaped slider 104 and the T-shaped chute 105. When protecting the wire rope 3 at the bending part, a combined bending working surface can be formed by the cooperation of the fixture unit 1, the connecting piece 5, the bolt 4 and the nut.

[0036] The change in the length of the detachable combined fixture is realized by assembling between several fixture units 1 to match the length change of the wire rope 3 in different contact areas. The connection in the length direction between the fixture unit 1 and the fixture unit 1 is formed by the T-shaped slider 104 at one end of the paired component 101 and the T-shaped chute 105 of the adjacent paired component 101, or the T-shaped chute 105 at one end of the paired component 101 and the T-shaped slider 104 of the adjacent paired component 101. The shape and size of the T-shaped slider 104 and the T-shaped chute 105 match. The T-shaped slider 104 can freely slide along the end face of the component 101 in the T-shaped chute 105. It is not only convenient and fast to splice, but also the fitting and clamping of the T-shaped slider 104 and the T-shaped chute 105 can be realized through the extrusion of the wire rope 3 and the fixture unit 1 and the gravity of the T-shaped slider 104.

[0037] The T-shaped slider 104 can either be integrally formed with the component 101 or be detachably connected through threaded cooperation. When the T-shaped slider 104 and the component 101 are detachably connected, the T-shaped slider 104 is an independent component with a threaded hole running through its center. A threaded blind hole is provided on the end face of the component 101. One end of the threaded rod is screwed into the threaded blind hole on the end face of the component 101, and the other end is screwed into the threaded hole of the T-shaped slider 104, thus realizing the connection between the T-shaped slider 104 and the component 101.

[0038] As Figures 8 to 10As shown, the change in the bend of the detachable combined fixture is achieved by the cooperative connection of the adjacent fixture units 1 through the connector 5, the bolt 4, and the nut, thereby forming protection for the wire rope 3 in the bending section at the contact with the equipment. A set of the connector 5, the bolt 4, and the nut are respectively arranged on both sides of the adjacent fixture unit 1. The connector 5 is a sheet body with round holes respectively arranged at both ends, and these two round holes are concentrically matched with the round hole sections in the stepped holes 108 of the two adjacent components 101 on the same side in the adjacent fixture unit 1. The middle section of the bolt 4 is a smooth shaft, one end of the smooth shaft is a bolt head, and the other end is a thread; the bolt 4 sequentially passes through the round hole at the end of the connector 5 and the round hole section and the square hole section in the stepped hole 108 of the component 101, and is tightly connected with the nut through its thread in the square hole section, and the step surface formed by the stepped hole 108 of the component 101 limits the nut. The bolt 4 realizes the hinged connection between the component 101 and the connector 5 with clearance fit between the shaft and the hole in the stepped hole 108 of the component 101. The two adjacent components 101 on the same side in the adjacent fixture unit 1 are both hinged to the same connector 5, thereby realizing the change in the bend between the adjacent fixture units 1. It can be seen that the cooperation of the connector 5 and the bolt 4 and the nut is to enable rotational movement. The specific structure of the connector 5 is not limited to that shown in the drawings, as long as the hinged connection at the joint can be realized and the rotation of the component 101 around the bolt 4 can be achieved.

[0039] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many specific transformations in form without departing from the spirit of the invention and the scope protected by the claims. All of these fall within the protection scope of the present invention.
