Abstract

The utility model provides a portal crane turns over sediment auxiliary device, a serial communication port, including setting up at the shoulder pole roof beam of portal crane below, setting up at the shoulder pole hook of shoulder pole roof beam bottom, setting up the fixed pin in the sediment fill both sides, the one end of shoulder pole hook articulates on the shoulder pole roof beam, and the other end passes through the fixed pin and the sediment is fought and is rotated the connection. The utility model discloses the sediment fill that will be equipped with dregs during the use passes through the shoulder pole hook and realizes being connected with portal crane below shoulder pole beam, under sediment fill self action of gravity, based on the focus position relation, when fully loaded, the focus position is higher than shoulder pole hook center line, the inclination reaches the biggest back, portal crane shoulder pole beam continues to transfer, realize empting of dregs, along with dregs reduction, the sediment fill dead weight reduces, continue to transfer the shoulder pole beam, the action of gravity that realizes the shoulder pole beam passes through the shoulder pole hook and passes power for the sediment fill, increase the deflection angle of sediment fill, make the dregs of sediment fill bottom and lateral wall empty out, solve the dregs and empty unclean problem, moreover, the steam generator is simple in structure, the processing is convenient, and the smoothness that the stone sediment was emptyd is improved.

Description

Gantry crane turns over sediment auxiliary device

Technical Field

The utility model belongs to the technical field of tunnel construction, concretely relates to portal crane turns over sediment auxiliary device.

Background

In the construction process of the underground tunnel, the excavated dregs need to be transported to a dregs pool at a designated position on the ground and then transported out of the engineering site. The method is characterized in that the muck in the underground construction process is generally carried to a muck bucket firstly, then the muck bucket is pulled by using a battery car or a diesel locomotive, the muck bucket is dragged to a tunnel entrance in a tunnel along the horizontal direction, the muck bucket is vertically lifted by using a portal crane, the muck in the muck bucket is unloaded in a ground muck pool, however, the stone slag constructed by double-shield TBM is easy to stick to the bottom and the side wall of the muck bucket and cannot be poured completely, and the flexible carrying pole hook adopted by a gantry crane muck turning mechanism causes the insufficient turning angle of the muck bucket, so that the stone powder is more easily stuck in the muck bucket and is difficult to pour out.

SUMMERY OF THE UTILITY MODEL

The utility model provides a gantry crane turns over sediment auxiliary device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a portal crane turns over sediment auxiliary device, includes the shoulder pole roof beam that sets up in the portal crane below, sets up the shoulder pole hook in shoulder pole roof beam bottom, sets up the fixed pin in the sediment fill both sides, the one end of shoulder pole hook articulates on the shoulder pole roof beam, and the other end rotates through fixed pin and sediment fill and is connected.

Preferably, the inside of the shoulder pole beam is filled with mortar.

Preferably, the connecting line of the fixing pin is positioned on the central line of the slag hopper close to the discharge end.

Preferably, the shoulder pole hook is a rigid structure and is made of a steel plate.

The utility model has the advantages that:

the utility model discloses on hanging shoulder pole roof beam with the sediment fill during the use, under sediment fill self action of gravity, based on the focus position relation, the inclination reaches the biggest back, and portal crane shoulder pole roof beam continues to transfer, realizes that the action of gravity of shoulder pole roof beam passes power through the shoulder pole hook and for the sediment fill, increases the deflection angle of sediment fill, finally reaches the purpose that improves the smoothness nature that the ballast emptyd.

Fig. 1 is a schematic structural view of the gantry crane slag-turning auxiliary device of the present invention;

in the figure: 1. shoulder pole beam, 2, shoulder pole hook, 3, fixed pin, 4, slag bucket.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a portal crane turns over sediment auxiliary device, is including setting up carrying pole roof beam 1, the carrying pole hook 2 of setting in carrying pole roof beam 1 bottom, setting at the fixed pin 3 of 4 both sides of sediment fill in the portal crane below, the one end of carrying pole hook 2 articulates on carrying pole roof beam 1, and the other end rotates through fixed pin 3 and sediment fill 4 and connects, the inside packing of carrying pole roof beam 1 has the mortar, realizes that carrying pole roof beam 1 increases weight to about 4 tons, the line of fixed pin 3 is located the 4 central lines of sediment fill and is close to the discharge end, carrying pole hook 2 is rigid structure, is made by the steel sheet.

The utility model discloses a theory of operation is: the slag bucket 4 filled with the slag soil is connected with a carrying pole beam 1 below the gantry crane through a carrying pole hook 2, based on the gravity center position relation, when the slag bucket 4 is fully loaded, the gravity center position is higher than the central connecting line of the carrying pole hook 2, after the inclination angle reaches the maximum, the carrying pole beam 1 of the gantry crane continues to be lowered, the dumping of the slag soil is realized, the self weight of the slag bucket 4 is reduced along with the reduction of the slag soil, the carrying pole beam 1 continues to be lowered, the gravity effect of the carrying pole beam 1 is realized, the force is transferred to the slag bucket 4 through the carrying pole hook 2, the deflection angle of the slag bucket 4 is continuously increased, the slag soil at the bottom and on the side wall of the slag bucket 4 is dumped, and the problem that the dumping of the slag soil is not clean is solved.

The utility model discloses simple structure, processing is convenient, changes into the steel sheet hook with original flexible shoulder pole hook, realizes connecting through fixed pin 3, can play the effect of biography, increases 4 corners of sediment fill, realizes improving the purpose of the smoothness nature that the stone sediment was emptyd.

While the preferred embodiments of the present invention have been described, it is to be understood that the invention is not limited to the precise embodiments described, and that equipment and structures not described in detail are understood to be practiced as commonly known in the art; any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention will still fall within the protection scope of the technical solution of the present invention by those skilled in the art without departing from the technical solution of the present invention.
