Technical Field

The utility model relates to an engineering construction machinery technical field particularly, relates to an automatic device that unloads of electronic grab bucket.

Background

In urban subway construction, open cut method construction accounts for a relatively high proportion in a subway construction method, subway lines are complex and complicated along with continuous development of urban rail transit, wire nets are more and more dense, a plurality of construction major and difficult point projects such as downward penetration and lateral penetration are generated, a plurality of foundation pits constructed by the open cut method are deeper and deeper, and the depth of the foundation pits brings challenges for the safety of vertical transportation of earthwork and stonework and the improvement efficiency.

The connecting rod piece of the electric grab bucket hoisting soil box in the existing design adopts double rigid welding rod pieces, the rod piece is very easy to damage under the action of pulling the steel wire rope with load bearing, and the soil box falls behind.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an automatic device that unloads of electronic grab, its hoist and mount that adopts one side rigidity flexonics connect, and the connecting rod can incline towards fixed direction partially to solve current problem.

The embodiment of the utility model discloses a realize through following technical scheme:

an electric grab bucket automatic soil unloading device, comprising: the top edge of one side of the box bucket is connected with the rigid hoisting member in a hinged mode, the top edge of the other side of the box bucket is connected with the flexible hoisting member, the top of the rigid hoisting member is connected with the top of the flexible hoisting member, a hoisting lug is arranged at the top of the rigid hoisting member, a notch is formed in the rigid hoisting member and used for enabling an opening to fall into soil slag from the upper side to the box bucket, and an earth unloading mechanism is arranged at the bottom of the box bucket.

Furthermore, the rigid hoisting member is a U-shaped member, and two bottom feet of the U-shaped member are connected with the top edge of the box bucket through hinges.

Furthermore, the U-shaped component is made of steel.

Further, the top of the U-shaped member is horizontally bent to form a horizontal hanging section.

Further, the flexible hanging member is a chain, and the number of the chains is two.

The former design hoist and mount case of electric grab bucket is fought connecting rod spare and is the rigid link pole, optimizes the back and be one side rigidity flexible connection, has following advantage and beneficial effect after optimizing:

1. the integral U-shaped steel member replaces the original welding rod piece, so that welding points are reduced, and the integrity of the rod piece is improved;

2. the high-strength iron chain replaces another welding rod piece, so that the strength is improved, and meanwhile, the probability that the broken stone is broken by the broken stone when the broken stone is loaded into the soil box is reduced;

3. the U-shaped steel member is combined with the high-strength iron chain to form a triangular flexible member, so that the U-shaped steel member automatically falls in a fixed direction, namely the direction of the iron chain after being lowered, external assistance is not needed, convenience is provided for an excavator driver when gravel is loaded, collision is avoided, and the soil loading efficiency is improved;

4. the mode that the original rod piece, the soil box and the steel wire rope are connected with the box hopper is changed, and the mode that the original box hopper, the rod piece and the steel wire rope are connected through shackles is changed into a hinged connection mode, so that the safety is improved, and the possibility of accidents is reduced;

5. the maintenance is simple, and the member is the finished product, and easy the change reduces and maintains for a long time, ensures that on-the-spot construction production is steadily impelled.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Referring to fig. 1, an automatic soil unloading device of an electric grab bucket includes: the box bucket comprises a box bucket 1, a rigid hoisting connection member 2 and a flexible hoisting connection member 3, wherein the top edge of one side of the box bucket 1 is connected with the rigid hoisting connection member 2 through a hinge, the top edge of the other side of the box bucket 1 is connected with the flexible hoisting connection member 3, the top of the rigid hoisting connection member 2 is connected with the top of the flexible hoisting connection member 3 to form a triangular flexible hoisting connection member 3, a hoisting connection lug 4 is arranged at the top of the rigid hoisting connection member 2 and is the position where a crane is hoisted and hung during hoisting, the box bucket 1 can be stably hoisted, after the box bucket 1 is placed down, the hoisting connection on the rigid hoisting connection member 2 is loosened, the bottom of the rigid hoisting connection member 2 is connected in a hinge mode, the rigid hoisting connection member 2 inclines towards the flexible hoisting connection member 3, finally, the rigid hoisting connection member 2 can be flatly placed on the box bucket 1, and after the box bucket 1 is placed down, the excavator needs to dig soil and pour into the box bucket 1, so that the rigid hoisting connection member 2 is provided with a gap, to provide an opening for the fall of the soil residue into the bucket 1 from above.

In the embodiment shown, the rigid suspension elements 2 are rectangular steel plates, but preferably are U-shaped elements made of steel, because the U-shaped elements are steel frame structures, which are lighter and naturally have a gap for the easy pouring of soil, and thus are connected to the top edge of the soil box by the two bottom legs of the U-shaped elements via the hinges 6. The flexible hanging and connecting member 3 is preferably a chain, two chains are arranged for stable hanging and connecting, the top of the U-shaped member is horizontally bent, namely a section of horizontal section is formed at the position of the U-shaped cross rod to form a horizontal hanging and connecting section 21, the stable hanging and connecting is facilitated, and the hanging and connecting lugs 4 are arranged on the horizontal hanging and connecting section 21.
