Abstract

The utility model discloses a detachable narrow-space clamping device hoister which comprises an extendible arm, ring arms, safety fasteners and hooks, wherein the extendible arm is arranged on a hoisting arm of a crane, and the other end thereof is connected with the two ring arms, the tail ends of the two ring arms are provided with the safety fasteners, and the two ring arms are respectively provided with two hooks. As the hoister is arranged on the end portion of the crane, the hoister can directly hoist heavy goods without using a hoisting rope, which greatly reduces the whole moving space of the hoisting arm and the heavy goods, realizes the hoisting effect of freely moving in narrow space on the premise of not changing the structure of the crane, and greatly reduces the hoisting height of the crane in the hoisting process, and improves the safety coefficient of construction.

Description

Detachable little space clasping formula equipment suspender

Technical field

The utility model belongs to crane accessory equipment technical field, particularly a kind of detachable little space clasping formula equipment suspender.

Background technology

In the time of electric operating or other aloft work, often need to use crane and lift by crane relevant appliance or equipment, and when using the crane hoisting heavy, the top of suspension arm of crane far above lifting by crane destination locations, is lifting rope and adjustment lifting rope distance because arm has a segment distance toward contact down often.But in some cases, often needed to pass by hoisting heavy from a narrow space, perhaps the destination of being lifted by crane is positioned at a relatively narrow space, concretely such as exchange device more in substation, because power failure scope restriction, the arm of common crane dare not stretch at all, have under the prerequisite of not large-area power-cuts, the lighter can easily lifting appliance, weight person can be because arm be too big with quilt lifting thing spacing, may meet other electric wires or equipment, causing has a power failure waits other safety misadventures, influences the reliability of safe operation and power supply.

The utility model content

The utility model provides a kind of detachable little space clasping formula equipment suspender that makes things convenient for hoisting heavy in little space.

A kind of detachable little space clasping formula equipment suspender, it comprises extension arm, ring arm, safety clasp and suspension hook, and described extension arm is arranged on the suspension arm of crane, and the other end connects described two ring arms, the end of two ring arms is provided with safety clasp, on two ring arms two suspension hooks is set respectively.

Because the utility model is arranged on the end of suspension arm of crane, directly embrace the lift heavy thing, need not use lifting rope, dwindle the mass activity space of arm and weight greatly, under the prerequisite that does not change the crane structure, realized the lifting effect that in little space, moves freely, and in the process of lifting, reduce the sling height of crane greatly, improved the safety factor of construction.In addition, the utility model adopts the design of clasping formula buckle, utilizes by the deadweight of lifting weight and keeps level, can realize comprehensive within the specific limits rotation, the equipment of being convenient to is installed, and at the end of two ring arms safety clasp is set, and further improves the lifting process safe.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a running condition reference diagram of the present utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of detachable little space clasping formula equipment suspender, it comprises extension arm 1, ring arm 2, safety clasp 3 and suspension hook 4, described extension arm 1 is arranged on the suspension arm of crane 5, the other end connects described two ring arms 2, the end of two ring arms 2 is provided with on 3, two rings of safety clasp arm 2 two suspension hooks 4 is set respectively.

Because the utility model is arranged on the end of suspension arm of crane, directly embrace the lift heavy thing, need not use lifting rope, dwindle the mass activity space of arm and weight greatly, under the prerequisite that does not change the crane structure, realized the lifting effect that in little space, moves freely, and in the process of lifting, reduce the sling height of crane greatly, improved the safety factor of construction. in addition, the utility model adopts the design of clasping formula buckle, utilization is kept level by the deadweight of lifting weight, can realize comprehensive within the specific limits rotation, and the equipment of being convenient to is installed, and safety clasp is set at the ends of two ring arms, further improve the lifting process safe.

Claims

1. detachable little space clasping formula equipment suspender, it is characterized in that: it comprises extension arm, ring arm, safety clasp and suspension hook, described extension arm is arranged on the suspension arm of crane, the other end connects described two ring arms, the end of two ring arms is provided with safety clasp, on two ring arms two suspension hooks is set respectively.
