Abstract
The utility model provides a roadheader and a slewing device thereof. The slewing device comprises a slewing bearing. The lateral side of the sewing bearing is provided with a mounting hole to be connected with a body of a roadheader. The mounting hole on the lateral side of the slewing bearing allows for connection between the lateral side of the slewing bearing with the body of the roadheader, and height of the body of the roadheader can be effectively decreased.
Description
Technical field
The utility model relates to engineering machinery field, is specifically related to a kind of development machine and slewing equipment thereof.
Background technology
At present, development machine has the plug-type and tooth bar hydraulic cylinder type of hydraulic cylinder with the kind of drive of panoramic table.But no matter be the plug-type transmission of hydraulic cylinder, or tooth bar hydraulic cylinder type, panoramic table all is to close by the plane vertical with the centre of gyration and body handle with being connected of body, causes the fuselage height to be difficult to effective reduction, can reduce the applicability of development machine in the tunnel and fuselage is high.
Therefore, demand providing a kind of development machine that can effectively reduce fuselage urgently, to improve its applicability in the tunnel.
The utility model content
For defects and the deficiency that overcomes prior art, the first purpose of the present utility model is to provide a kind of slewing equipment of being convenient to effectively reduce machine body of boring machine, comprising: revolving bed; The side of described revolving bed is provided with the pilot hole that is connected for the development machine body.
Further, the side of described revolving bed comprises the first side and the second side, is provided with at least one described pilot hole on each side.
Further, be provided with two described pilot holes on described the first side; And/or be provided with two described pilot holes on described the second side.
The utility model also provides a kind of development machine, comprises above-mentioned any slewing equipment, connector and development machine body; Described slewing equipment is connected with described development machine body by the connector that passes described pilot hole.
Further, described connector is pin or bolt.
The utility model development machine arranges pilot hole by the side at revolving bed, to realize that revolving bed connects with the development machine body from the side, is convenient to effectively reduce the fuselage height, increases the compliance of development machine downhole production.
Description of drawings
Fig. 1 is the slewing equipment example structure schematic diagram of the utility model development machine;
Fig. 2 is the lateral view of Fig. 1;
Fig. 3 comprises the as shown in Figure 1 structural representation of the development machine of slewing equipment;
Fig. 4 is the lateral view of Fig. 3;
Fig. 5 is the partial enlarged drawing at I place among Fig. 4.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The slewing equipment embodiment of the utility model development machine can be slewing equipment 1 as shown in Figures 1 and 2, and it comprises: revolving bed 11; The side of revolving bed 11 is provided with the pilot hole 111 that is connected for the development machine body.
During concrete operations, the side of revolving bed 11 comprises the first side and the second side, is provided with at least one pilot hole 111 on each side, and concrete quantity can arrange according to actual needs.As shown in Figure 1, be provided with two pilot holes 111 on the first side and the second side; Certainly, can two pilot holes 111 be set a side in the first side and the second side according to actual needs.
Like this, the development machine body can be by the plane parallel with the centre of gyration of slewing equipment 1 from the side closing, close by the plane vertical with the centre of gyration and body handle than prior art, be convenient to effectively reduce the machine body of boring machine height, improve development machine in downhole production, such as the compliance of operation in the tunnel.
As shown in Figure 3-Figure 5, the utility model development machine comprises as shown in Figure 1 slewing equipment 1, connector 2 and development machine body 3; Slewing equipment 1 is connected with development machine body 3 by the connector 2 that passes pilot hole 111.
During concrete operations, connector 2 can be bolt etc.When being provided with two pilot holes 111 on the first side of revolving bed 11 and the second side and each side, the quantity of connector 2 is four.Preferably, connector 2 can for pin connect, be compared the connected mode that adopts bolt and improve the reliability that connects.
The utility model slewing equipment embodiment arranges pilot hole by the side at revolving bed, to realize that revolving bed connects with the development machine body from the side, the mode that revolving bed and development machine body are connected up and down in the prior art, be convenient to effectively reduce the fuselage height, increase the compliance of development machine downhole production; Preferably, connect place of bolt with pin and connect, improved the reliability that connects; In addition, the development machine example structure compactness, the reliable operation that comprise above-mentioned slewing equipment.
Below only be preferred embodiment of the present utility model, in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
