Abstract

The utility model discloses a movable hatch cover used on a crane. The movable hatch cover comprises a walking platform (1) with a hatch and a hatch cover body (2), wherein rails (3) are symmetrically arranged on two sides of the hatch on the side wall of the walking platform (1), and two ends of the hatch cover body (2) are arranged on the rails (3).The movable hatch cover has the advantages of simple structure and convenience in manufacturing and opening and closing of the hatch with the adoption of the movable hatch cover, thereby preventing the occurrence of interference phenomenon.

Description

A kind of for the hatch booby on the crane

Technical field

The utility model relates to a kind of crane, and is particularly a kind of for the hatch booby on the crane.

Background technology

At present, be provided with hatch with hatch board walking on stage of crane, existing hatch board mainly is that the form by hinge is connected to the hatch place, but, this connected mode owing to being subject to the restriction of size, does not allow hatch board upwards to open by the mode of hinge for some crane, because in case open and will interfere with other mechanism or structural member, and then the personnel that cause can't arrive the crane predetermined position by hatch board.

The utility model content

The purpose of this utility model just provides that a kind of convenience opens, prevents from interfering is used for hatch booby on the crane.

The purpose of this utility model is to realize by such technical scheme, a kind of for the hatch booby on the crane, comprise walking on stage and the hatch board body with hatch, on the sidewall of walking on stage and the bilateral symmetry that is positioned at hatch be provided with track, the two ends of described hatch board body arrange in orbit.

Wherein, described track comprises angle steel and round steel, and on described angle steel vertically was arranged on and walks on stage, described round steel was provided with on the angle steel inside wall.

In order to prevent that the hatch board body from skidding off track, is provided with buckle at the two ends of track.

In order to make things convenient for the opening and closing hatch, below the middle part of hatch board body, and be positioned at and be provided with handle on the two side.

Owing to having adopted technique scheme, the utlity model has simple in structure, easily manufactured advantage, adopt its easily opening and closing hatch board, prevented the generation of interference.

Description of drawings

Description of drawings of the present utility model is as follows:

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

Fig. 2 is the top view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.

Embodiment 1: as shown in Figure 1, 2, a kind of for the hatch booby on the crane, comprise with hatch walk on stage 1 and hatch board body 2, on 1 sidewall of walking on stage and the bilateral symmetry that is positioned at hatch be provided with track 3, the two ends of described hatch board body 2 are arranged on the track 3.

Wherein, track 3 of the present utility model comprises angle steel 4 and round steel 5, and described angle steel 4 vertically is arranged on walks on stage on 1, and described round steel 5 is provided with on angle steel 4 inside walls.

Further, be provided with buckle 6 at the two ends of track 3.Doing like this can be so that when the hatch board body slided into the track termination, buckle retrains it can not skid off track.

In order to make things convenient for opening and closing hatch board body, below the middle part of hatch board body 2, and be positioned at and be provided with handle 7 on the two side.

The utility model is to use like this: the operator slides at round steel 5 by handle 7 pulling hatch board bodies 2, so just can open or close hatch, and is simple and convenient, can also be so that hatch board can not interfered other mechanism and structural member.
