Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a sling for transporting slender materials. Background Art

[0002] In the field of industrial material handling, it is generally necessary to transport slender materials of different materials, lengths and diameters.

[0003] When the diameter and hardness of the material are of a certain standard, such as relatively thick steel pipes or plastic pipes, a grab hook or rope loop structure can be used in conjunction with lifting equipment to lift the material.

[0004] However, when the diameter of slender materials is relatively thin, such as steel bars, outer packaging is usually required to wrap the steel bars into bundles, and then the slender materials are hoisted and transferred by suspending the outer packaging.

[0005] However, materials such as steel bars are mostly piled up, and packaging and transferring them in the above manner will cause serious waste of manpower and material resources, and seriously affect the progress, resulting in high transportation costs and delays in construction period.

[0006] In order to solve the above problems, it is necessary to develop a sling suitable for slender materials, especially steel bars, to improve handling efficiency and save transportation costs. Utility Model Content

[0007] The purpose of the utility model is to address the deficiencies of the prior art and thereby provide a sling for transporting slender materials that can easily grab and stack and improve the transfer efficiency of slender materials.

[0008] In order to achieve the above-mentioned object, the technical solution adopted by the present utility model is as follows: a sling for carrying slender materials, comprising a sling beam, several sling mechanisms, an electric control system and a hydraulic system;

[0009] A plurality of the hoisting mechanisms are installed below the hanging beam at intervals along the length direction of the hanging beam;

[0010] Each of the hoisting mechanisms includes a connecting rod mechanism and a pair of clamping jaws driven by the connecting rod mechanism, wherein the clamping surfaces of the clamping jaws are provided with arc plates, and the arc plates on the pair of clamping jaws are assembled to form a pocket shape for grasping and supporting slender materials;

[0011] The electronic control system is used to control the movement of the hoisting mechanism, and the hydraulic system is used to provide power for the hoisting mechanism.

[0012] Preferably, each of the hoisting mechanisms is connected to the hydraulic system via an oil pipeline, and the oil pipeline is laid along the inside or outside of the hoisting beam.

[0013] Preferably, the surface of the arc plate is paved with nylon pads or the material of the arc plate is nylon.

[0014] Preferably, the connecting rod mechanism includes a connecting rod seat fixed on both sides of the hanging beam, a connecting rod hinged to the connecting rod seat, a clamping claw hinged to the connecting rod and a hydraulic cylinder. A pair of clamping claws are hinged by a pin shaft to form a clamping part, and a hydraulic cylinder for driving the clamping claws to move is installed on the hanging beam.

[0015] Preferably, each of the lifting mechanisms includes two groups of connecting rod mechanisms and pairs of clamps arranged parallel to each other, a connecting shaft is installed between two adjacent clamps in the two groups, and one end of the hydraulic cylinder is installed on the lifting beam and the other end is installed on the connecting shaft.

[0016] Preferably, the cylinder bottom of the hydraulic cylinder is hinged to the connecting seat, the connecting seat is fixed to the bottom end of the hanging beam, and the telescopic rod end of the hydraulic cylinder is hinged to the connecting shaft.

[0018] Preferably, the number of the lifting mechanisms is between 3 and 6.

[0019] Preferably, the hoisting mechanisms are arranged at equal intervals.

[0020] Preferably, two hanging holes are provided at symmetrical positions on the top end of the hanging beam.

[0021] The present invention has substantial features and progress compared with the prior art. Specifically, the present invention is based on a sling composed of a lifting beam and several lifting mechanisms. The execution end of the lifting mechanism is designed as a clamp, and an arc plate is provided on the inner side of the clamp, which forms a pocket-shaped structure when closed. For slender materials, on the one hand, several slender materials can be gathered and lifted by clamping, and on the other hand, the arc plate plays a role in local support and protection of the slender materials to avoid scattering of the slender materials. On the other hand, when a nylon pad is provided on the surface of the arc plate or the material of the arc plate is designed to be nylon material, it can provide greater friction to maintain the stability of the lifted slender materials during the lifting process.

[0022] During hoisting work, the hoisting can be completed directly by performing the actions of grabbing, lifting and stacking. The staff only needs to remotely control it through the control system or remote control, which is very convenient.

[0023] This sling is suitable for slender materials of various specifications and models, such as steel pipes, rubber pipes, various metal or non-metallic bars, etc. Compared with traditional slings, it has the advantages of convenience and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of the present utility model is further described in detail below through specific implementation methods.

[0029] like Figure 1-Figure 3 As shown, a sling for carrying slender materials includes a sling beam 1, several sling mechanisms, an electric control system 3 and a hydraulic system 2.

[0030] The hanging beam 1 is made of common steel such as square steel or H-shaped steel. Two hanging holes 4 are symmetrically arranged at the top of the hanging beam for cooperating with power machinery such as a crane.

[0031] Several of the hoisting mechanisms are installed below the hanging beam 1 at intervals along the length direction of the hanging beam 1. In this embodiment, the number of the hoisting mechanisms is 6 and they are arranged at equal intervals.

[0032] Each of the lifting mechanisms includes a connecting rod mechanism and a pair of clamps 8 driven by the connecting rod mechanism, wherein the connecting rod mechanism includes a connecting rod seat 5 fixed on both sides of the hanging beam 1, a connecting rod 7 hinged to the connecting rod seat 5, a clamping jaw 8 hinged to the connecting rod 7 and a hydraulic cylinder 11, a pair of clamping jaws 8 are hinged by a pin shaft 6 to form a clamping part, and a hydraulic cylinder 11 for driving the clamping jaw 8 is installed on the hanging beam 1. Specifically, the bottom of the hydraulic cylinder 11 is hinged to the connecting seat 12, and the connecting seat 12 is fixed to the bottom end of the hanging beam 1, and the telescopic rod end of the hydraulic cylinder 11 is hinged to the connecting shaft 13, and the connecting shaft 13 is a pin shaft passing through two adjacent clamping jaws 8 in the same group.

[0033] The clamping surface of the clamping jaws 8 is provided with an arc plate 9 , and the arc plates 9 on a pair of clamping jaws 8 are assembled to form a pocket shape for grabbing and supporting the slender material 14 .

[0034] In some embodiments, the surface of the arc plate 9 is paved with nylon pads for supporting and protecting the slender materials. In other embodiments, the arc plate itself is made of nylon material.

[0035] Nylon pads or nylon arc plates themselves have good anti-slip and supporting properties. In the process of clamping and transferring slender materials, nylon pads or nylon arc plates can provide good support and stable friction for slender materials, avoiding problems such as slipping or falling of slender materials.

[0036] In order to provide a stable clamping force, each of the lifting mechanisms includes two groups of connecting rod mechanisms and paired clamps arranged parallel to each other, and the connecting shaft 13 is installed between two adjacent clamps in the two groups. One end of the hydraulic cylinder is installed on the connecting seat 12, and the other end is installed on the connecting shaft.

[0037] The electric control system is used to control the action of the hoisting mechanism. In a preferred embodiment, the electric control system is equipped with a remote controller for inputting action instructions via the remote controller.

[0038] The hydraulic system is used to provide power for the hoisting mechanisms. Each of the hoisting mechanisms is connected to the hydraulic system via an oil pipeline, and the oil pipeline is laid along the inside or outside of the hoisting beam.

[0039] In other embodiments, the number of the hoisting mechanisms can be changed according to the specific length of the slender material, and is generally between 3 and 6.

[0040] When in use, the operator first operates the lifting equipment to move the spreader above the stacked slender materials, then moves it down to the corresponding height while remotely controlling the hydraulic cylinder to drive the clamping jaws to open. After grabbing a certain amount of material, the hydraulic cylinder is pressure-controlled to drive the clamping jaws to close, and the material is clamped between the two clamping jaws.

[0041] By sending lifting instructions to the electronic control system and moving the spreader, the material can be transported to the designated location. The electronic control system then controls the hydraulic system to operate, the hydraulic cylinder contracts, the clamping jaws are opened, and the slender material falls under the action of gravity, completing the unloading action.

[0042] The nylon pads on the jaws can protect slender materials and extend the service life of the spreader.

[0043] This solution is suitable for a wide range of slender materials, including slender steel pipes, rubber hoses, and various metal and non-metallic bars. Equipped with a hydraulic station, electronic control system, and gripper monitoring device, this spreader enables one-touch grabbing and stacking, as well as remote operation. It offers convenient use, reliable performance, safety, and efficiency.

[0044] Finally, it should be noted that: The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
