Description
Technical field
The present invention relates to development machine, specifically a kind of panoramic table structure of development machine.
Background technology
Development machine is a kind of machine for digging straight underground passage or massif tunnel, primarily of compositions such as walking mechanism, body frame, operating mechanism, slew gears.In prior art, operating mechanism is fixed in the connecting hole of slew gear by connecting bearing pin, panoramic table and pivoting support is mainly comprised in slew gear, panoramic table is connected with body frame by pivoting support, panoramic table rotates with pivoting support, and drive the revolution of operating mechanism, realize the left and right reciprocating operation of operating mechanism to increase the cut coverage of development machine.
In prior art, the structure of panoramic table is monolithic, itself and operating mechanism connected mode be that mode by penetrating bearing pin realizes, in assembling process, operating mechanism needs to be sling by servicing unit, and then the pin-and-hole of its pin-and-hole and panoramic table is aimed at, the process of this pin-and-hole location is extremely slow, and again because bearing pin size and deadweight are comparatively large, the process penetrated by bearing pin is comparatively loaded down with trivial details and effort also; In addition, when detachable maintaining, need first operating mechanism to be sling, and the stable of the relative position of operating mechanism and panoramic table need be ensured, then the bearing pin of operating mechanism both sides could be extracted, because the size of bearing pin is comparatively large with deadweight, so the operation easier of extracting bearing pin is large, time-consumingly to require great effort again, for the dismounting of development machine operating mechanism and maintenance inconvenience very.
Summary of the invention
For the deficiency that prior art exists, the invention provides a kind of panoramic table structure for development machine, can realize assembling fast with operating mechanism, and make the process of the dismounting of operating mechanism and maintenance more convenient.
To achieve these goals, the invention provides a kind of panoramic table structure for development machine, comprise panoramic table main body, upper cover body, large end cap, described panoramic table main body is connected with the body frame of development machine by pivoting support, described panoramic table main body is provided with the semicircular panoramic table pin-and-hole caved in the direction to body frame on the position corresponding with the pin shaft hole in operating mechanism, described upper cover body is arranged on the top of described panoramic table pin-and-hole, described upper cover body is provided with the semicircular lid pin-and-hole identical and opposite disposed with it with described panoramic table pin-and-hole aperture, described panoramic table main body is fixedly connected with described upper cover body, the two ends of described panoramic table pin-and-hole are provided with main body boss, the two ends of described lid pin-and-hole are provided with lid boss, described main body boss is arranged around the excircle of panoramic table pin-and-hole, described lid boss is arranged around the excircle of lid pin-and-hole, the middle part of described large end cap is provided with the cylindrical recess of mating with panoramic table pin-and-hole and lid boss, described recess is buckled on described main body boss and described lid boss.
In this technical scheme, by monolithic panoramic table of the prior art is changed into split type, when installation work mechanism, can directly the bearing pin that operating mechanism two ends connect be fallen in panoramic table body pin, again upper cover body is fixed in panoramic table main body, being assembled with of operating mechanism can be realized fast; Dismantle and maintenance time, first upper cover body and panoramic table main body separate, operating mechanism just energy directly remove from panoramic table main body, dismantle with regard to Neng Shi operating mechanism and maintenance process more easily convenient; Arrange along the excircle of pin-and-hole by making main body boss and lid boss, it is made to link together by the large end cap with recess again, such shearing force can offset operating mechanism and because of revolution action, the junction of split type panoramic table be produced, thus split type panoramic table can be made to have better load bearing stength to operating mechanism, in addition, also the contact area of upper cover body and panoramic table main body can be increased, the constant intensity between upper cover body and panoramic table main body can be increased like this, thus make the connection of upper cover body and panoramic table main body more firm.
Further, described panoramic table main body and upper cover body are equipped with keyway on contact surface opposite each other, are provided with key plate in described keyway.
In this technical scheme, by being provided with keyway on the contact surface of panoramic table main body and upper cover body, and key plate is placed in keyway, effectively can prevent the relative sliding between upper cover body and panoramic table main body, the shearing force that the junction between upper cover body and panoramic table main body produces because of revolution action can be offset further simultaneously, thus split type panoramic table can be made to have better load bearing stength to operating mechanism.
Further, described key plate is fixedly connected with the keyway in panoramic table main body by bolt.
In this technical scheme, by making key plate be fixed in keyway, key plate can be prevented relative to the slip of panoramic table main body or upper cover body, thus facilitate the assembling of operating mechanism, also can guarantee that in work or assembling process, key plate can not drop simultaneously.
Further, the two ends of described upper cover body and panoramic table main body are provided with bolt hole, and described large end cap is fixedly connected with panoramic table main body with upper cover body by bolt.
In this technical scheme, by bolt, large end cap is fixedly connected with main body boss and lid boss, the bonding strength of upper cover body and panoramic table main body can be strengthened further.
Further, described upper cover body is being provided with bolt hole with panoramic table body contact end, and upper cover body is fixedly connected in panoramic table main body by lock washer by bolt.
In this technical scheme, by the contact jaw of upper cover body with panoramic table main body being connected with lock washer with lock bolt, can being expediently separated of lid and panoramic table main body.
Further, described large end cap is provided with circular hole at the center away from main body boss side, is provided with screwed hole uniformly in described circular, is fixedly connected with by bolt with the small cover of described circular hole adaptation with large end cap.
In this technical scheme, by the setting of this circular hole, to bearing pin charging-up lubricant oil, and maintenance can be conducive to.
In sum, the present invention when panoramic table main body and pivoting support connected mode constant, monolithic panoramic table is divided into upper cover body and panoramic table main body two parts, thus the Assembly And Disassembly of panoramic table and operating mechanism can be realized efficiently, by the design of boss and large end cap, split type panoramic table can be made to have better load bearing stength to operating mechanism, effectively can offset operating mechanism when revolution action to the shearing force that split type panoramic table junction produces simultaneously.
