Description

The field of technology.

The inventive utility model relates to elements of hoisting devices designed to engage various loads.

The prior art.

The prior art grab lifting device, made in the form of a one-horned hook containing a hole for attachment to a lifting device, described in GOST 25573-82 "Cargo rope slings for construction" [1]. In accordance with clause 4.3 [1], such a hook contains a safety lock, for example, a spring lock or a lock that locks under the action of its own weight (clause 2 of GOST 12840-80 “Safety locks for one-horned hooks Types and sizes” [2] ) Hooks [1] are used in large quantities during loading and unloading operations with various cargoes.

However, for some goods, the use of hooks [1] is difficult. For example, to move the basket for loading and transporting automobile semi-trailers on a platform car described in patent RU 189 337 (published May 21, 2019 Bull. No. 15, [3]), it is difficult to grasp the basket eyes with such hooks, since the semi-trailer is placed close to eyes, which prevents the hook from hooking the eye and closing the hook lock.

The specified drawback is deprived of the grip of the traction device selected as a prototype, made in the form of a hook with an L-shaped cross section formed by a vertical wall and a horizontal shelf with a tooth, the vertical wall of which contains a hole for attaching to the device, for example, a hook wide from the RedHotDot brand (publication in the Internet http://www.redhotdot.ru/Product.aspx/Details/53306, 07/12/2019, [4]).

The advantage of such a grip is that for its hooking to the eye, it is necessary to bring it only from the outer part of the eye, as opposed to hooks [1], for hooking of which free access is required both from the outer and the inner part of the eye.

However, the prototype [4] does not contain locks or other elements securing it to the eye of the load, as a result of which, when the cargo is hooked, it is necessary to hold the grip in the eye in advance in order to prevent the grip and eye from disengaging until the load is lifted.

Accordingly, the use of such a gripper leads to an increase in the complexity of loading and unloading operations, since if there are several eyes on the cargo, an appropriate number of workers is required to pre-hold the grips in the eyes before the load begins to lift.

The technical problem, the solution of which is provided when implementing or using the utility model, is the inability to reliably fix the grip to the eye before the start of the ascent.

Disclosure of the essence of the technical solution.

The technical result provided by the utility model is to reduce the complexity of loading and unloading.

The specified technical result is achieved due to the fact that the capture of the lifting device for moving metal loads is made in the form of a hook with an L-shaped cross section formed by a vertical wall and a horizontal shelf with a tooth. In this case, the vertical wall contains a hole for attaching the gripper to the lifting device. In this case, the capture housing is equipped with a permanent rare-earth magnet.

The permanent magnet may be located in the vertical wall of the hook or the horizontal grip shelf.

In a particular case, the capture is equipped with a removable neodymium or samarium magnet.

The proposed utility model is illustrated by graphic material: the figure shows a General view of the capture of a lifting device for moving metal loads.

Implementation of a technical solution.

The gripper of the lifting device for moving metal loads is made in the form of a hook with an L-shaped cross section formed by a vertical wall 1 and a horizontal shelf 2 with a tooth. The vertical wall 1 contains a hole 3 for attachment to a lifting device.

 The capture is equipped with a permanent rare-earth magnet 4. In a particular case, the magnet 4 can be located in a vertical wall 1 or a horizontal shelf 2 capture.

When caught by the capture of an eye of a metal load, under the action of the attractive force of a permanent magnet 4, the grip is securely fixed to the eye of the load being lifted.

The use of rare-earth neodymium or samarium magnet 4 is due to the following reason. It is known from the prior art that magnetically hard materials based on rare-earth metals have higher magnetic parameters compared to cast and ferrite materials with significantly smaller sizes and weights. The magnetic energy of magnets based on samarium is 6 times higher, and based on neodymium - 10 times higher than that of ferrite magnets (Pletnev S.V. Magnetic field, properties, applications. - St. Petersburg: Humanistics, 2004. - 624 p. - ISBN 5-86050-198-6, [5]).

Thus, the claimed utility model differs from the prototype in that the capture is equipped with a permanent rare-earth magnet.

Order of use

When engaging the transported cargo, the horizontal shelf 2 capture lead under the eye of the transported cargo from the outside of the cargo. Under the action of the attractive force of the permanent magnet 4, the grip is securely fixed to the eye of the load being lifted.

Industrial applicability.

The inventive utility model is implemented using industrially produced devices and materials, can be manufactured at any machine-building enterprise, and will find wide application in the implementation of loading and unloading operations with metal goods.
