Abstract
The utility model relates to a detachable front rack of a rotating base and belongs to the technical field of tunneling machines. The detachable front rack comprises a front rack body and a rotating base located in front of the upper part of the front rack body, wherein the front rack body and the rotating base are connected and fixed through a plurality of bolts and nuts. According to the detachable front rack of the rotating base, the rotating base and the front rack body are connected and fixed through the plurality of bolts and nuts, the rotating base and the front rack body are connected into a whole when excavation work is performed; when the tunneling machine transports or descends into a well, the rotating base can be detached from the front rack body, the transport weight of the tunneling machine is decreased, descending of the tunneling machine is facilitated, and the operation of a worker is facilitated at the same time.
Description
Technical field
The utility model relates to the Boring Machine Technique field, the detachable forebay of rotary table on espespecially a kind of development machine.
Background technology
Along with the development of China's coal-mine industry, increasing to the power requirement of development machine.Yet the development machine that power is larger, its weight and appearance and size are just larger.The forebay of existing development machine comprises the forebay body, and the upper surface front portion of mmi machine frame body is welded with rotary table.This structural volume is large, weight is large, makes troubles to development machine transportation, and when development machine goes down into a mine, because this structural volume, weight are large, very inconvenient going into the well operates to the workman and to have brought inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of rotary table detachable forebay, and it can make things convenient for the development machine transportation, and when development machine was gone into the well, weight can alleviate, volume reduces, and made things convenient for the workman to operate.
To achieve these goals, technical solution of the present utility model is: the detachable forebay of a kind of rotary table, comprise the forebay body and be positioned at rotary table anterior above the forebay body, be connected and fixed by several screw bolt and nut between wherein said forebay body and the rotary table.
The detachable forebay of the utility model rotary table, the upper surface of wherein said forebay body is provided with the first keyway, and the bottom of described rotary table is provided with second keyway corresponding with the first keyway position, places flat key in described first and second keyway.
The detachable forebay of the utility model rotary table, wherein said forebay body and rotary table are cast member.
After adopting such scheme, the detachable forebay of the utility model rotary table is connected and fixed rotary table and forebay body by several screw bolt and nut, when carrying out excacation, rotary table and forebay body link together, and when development machine transports or goes into the well, rotary table can be disassembled from the forebay body, so just alleviated the hauled weight of development machine, conveniently go into the well simultaneously, make things convenient for the workman to operate.
Description of drawings
Fig. 1 is the right view of the detachable forebay of the utility model rotary table;
Fig. 2 is the forebay body top view of the detachable forebay of the utility model rotary table;
Fig. 3 is the top view of the detachable forebay of the utility model rotary table.
Below in conjunction with accompanying drawing, by embodiment the utility model is described further;
The specific embodiment
As shown in Figure 1 to Figure 3, the detachable forebay of the utility model comprises forebay body 1 and is positioned at rotary table 2 anterior above the forebay body 1.Forebay body 1 and rotary table 2 are cast member.Be connected and fixed by several bolts 3 and nut 4 between forebay body 1 and the rotary table 2.The upper surface of forebay body 1 is processed with the first keyway 5, and the bottom of rotary table 2 is processed with second keyway 6 corresponding with the first keyway 5 positions.The first keyway 5 and the second keyway 6 interior placement flat keys 7.
The detachable forebay of the utility model rotary table is connected and fixed forebay body 1 and rotary table 2 by several bolts 3 and nut 4, and place flat key 7 between mmi machine frame body 1 and the rotary table 2, can bear larger shearing force and turning torque.When carrying out excacation, rotary table 2 links together with forebay body 1; And when development machine transports or goes into the well, rotary table can be disassembled from the forebay body, so just alleviated the hauled weight of development machine, conveniently go into the well simultaneously, make things convenient for the workman to operate; Forebay body 1 is cast member with rotary table 2, and it has the advantages such as compliance is extensive, with low cost.
Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
