Description

CAPTURE FOR PLATFORM

The utility model relates to load-gripping devices for block-type cargoes such as platforms and can be used for transportation of products of concrete products factories on platforms-trolleys.

A load-gripping device is known, suspended on a flexible sling from a load-lifting mechanism and including a housing with a gripping hook, support and hook elements (see St. RF No. 16730, MKI B66 C 1/42, publ. In Bulletin No. 4 for 2001).

However, the known device cannot be used on platforms-trolleys during transportation of reinforced concrete products on them in connection with the execution of its body in the form of a bracket, which makes it impossible to capture the platform and its transportation together with the reinforced concrete products located on it.

Also known is a grip for the platform, containing devices located on both sides of the platform, suspended on flexible slings from a load-lifting mechanism, each of which includes a housing with a gripping hook, support and hook elements (see the book: Ivashkov I.I. Installation, operation and repair hoisting-and-transport machines. -M.: Mechanical Engineering, 1981. - 145p.).

However, the known device is not convenient enough and reliable and cumbersome when transporting platforms with reinforced concrete products, which limits its use.

The technical result of the claimed device is the expansion of operational capabilities, improving the reliability and ease of operation.

The specified technical result is achieved by the fact that in the grip for the platform, containing devices placed on both sides of the platform, suspended on flexible slings from a load-lifting mechanism, each of which includes a housing with a gripping hook, support and hook elements, the housing of each hook device is made L- shaped and equipped with a plate placed on the inner side along a long shelf of the housing perpendicular to its short shelf, and a support bar with an emphasis on the end mounted on the plate with the possibility of interaction Twisted from the bottom of the platform and engaged with an emphasis on the bottom of the platform, which is made with external protrusions on the side surfaces, while the housing plate of each hook device is made with an inclined groove for interacting with the external protrusion of the platform with the possibility of moving and rotating the hook device around the protrusion of the platform.

In FIG. 1 shows the claimed capture for the platform, side view; in FIG. 2 is a view A in FIG. 1; in FIG. 3 - remote element B in figure 1 in a scale of 5: 1; in FIG. 4 is a view B in FIG. 3.

The grip for the platform contains devices 2 placed in pairs on two sides of the platform 1, suspended on flexible slings 3 to the lifting mechanism 4. Each device 2 is a hook and includes a housing 5 with a gripping hook 6 connected to the flexible sling 3. The housing 5 is made L- shaped and equipped with a plate 7 and a support plate 8 with a stop 9 at the end. The plate 7 is placed on the inner side along the long shelf of the housing 5 perpendicular to its short shelf. The support plate 8 is mounted on the plate 7 with the possibility of interaction with the bottom 10 of the platform 1 and engagement with a stop 9 for the bottom 10 of the platform 1. The platform 1 is made with external protrusions 11 on the side surfaces, for example in the form of axes. The plate 7 of the housing 5 of each device-hook 2 is made with an inclined groove

12 for interacting with the outer protrusion 11 of the platform 1 with the ability to move and rotate the hooking device 2 around the protrusion 11 of the platform 1.

Capture for the platform works as follows.

To lift and move the platform 1 together with reinforced concrete products, the grip for the platform is hung on the hook of the crane 4. At the same time, the hooking devices 2 connected to the grip lines 3 by means of the gripping hooks 6 are under their own weight. The device is controlled by a crane operator from the crane cabin, which lowers the hooking devices 2 down. The hooker connects each hook device 2 to the platform 1, introducing the protrusion 11 into the groove 12 of the plate 7 of the housing 5 and pushing the support shelf 8 with the stop 9 under the bottom of the platform 1, in particular under the channel of the channel 10, until the plate 7 touches the side surface of the platform 1, in particular, the vertical wall of the channel 10. Under the action of its own weight, the hook device 2 rotates around the protrusion-axis 7 and clings to the bottom of the platform 1, that is, to the shelf of the channel 10, when the sling 3 is lifted, each hook device 2, due to the interaction protrusion 11 and inclined pa and 12, is rotated in the opposite direction, and the support plate 8 engages the lower flange 10 platform sill 1 and the stop 9 captures last (shelf sill 10) across its width. In this case, the protrusions 11, occupying the lower position in the inclined grooves 12, still have the possibility of longitudinal downward movement, which guarantees the reliability of the grip platform 1 and further the reliability of its transportation.

Claims (1)

Platform grip, comprising devices placed on both sides of the platform, suspended on flexible slings from a load-lifting mechanism, each of which includes a housing with a gripping hook, support and hook elements, characterized in that the housing of each hook device is L-shaped and provided with a plate placed on the inside along the long shelf of the housing perpendicular to its short shelf, and a support bar with an emphasis on the end mounted on the plate with the possibility of interaction with the bottom of the platform and engagement a bottom abutment for the platform which is provided with external projections on the side surfaces, wherein each casing plate-hook device is provided with an inclined groove for interaction with outer ledge movable platform and the hook pivot-projection device around the platform.
