Description
Technical field
The present invention relates to development machine, the rotary table structure of a kind of development machine.
Background technology
Development machine is a kind of for digging straight underground passage or the machine in massif tunnel, mainly by walking mechanism, body frame,
Operating mechanism, slew gear etc. form.In prior art, operating mechanism is fixed on the connection of slew gear by connecting bearing pin
In hole, mainly including rotary table and pivoting support in slew gear, rotary table is connected with body frame by pivoting support, returns
Turntable rotates with pivoting support, and drives the revolution of operating mechanism, it is achieved the left and right reciprocating operation of operating mechanism increases driving
The cut coverage of machine.
In prior art, the structure of rotary table is monoblock type, its with operating mechanism connected mode be the side by penetrating bearing pin
Formula realizes, and during assembling, operating mechanism needs to be sling by auxiliary device, the most again by its pin-and-hole and rotary table
Pin-and-hole is directed at, and the process of this pin-and-hole location is extremely slow, relatively big due to bearing pin size and deadweight again, the mistake penetrated by bearing pin
Journey is the most relatively complicated and laborious；Additionally, when detachable maintaining, need first operating mechanism to be sling, and working machine need to be ensured
Stablizing of the relative position of structure and rotary table, then could extract the bearing pin of operating mechanism both sides, due to bearing pin size and
Deadweight is relatively big, so the operation easier extracting bearing pin is big, time-consuming laborious again, non-with maintenance for the dismounting of development machine operating mechanism
Normal inconvenience.
Summary of the invention
The deficiency existed for prior art, the present invention provides a kind of rotary table structure for development machine, it is possible to realize and work
Make mechanism quickly to assemble, and make dismantling of operating mechanism more convenient with the process of maintenance.
To achieve these goals, the present invention provides a kind of rotary table structure for development machine, including rotary table main body, on
Lid, big end cap, described rotary table main body is connected with the body frame of development machine by pivoting support, and described rotary table main body exists
The position corresponding with the pin shaft hole in operating mechanism is provided with the semicircular rotary table pin-and-hole to the direction of body frame depression,
Described upper cover body is arranged on the top of described rotary table pin-and-hole, and described upper cover body is provided with identical with described rotary table pin-and-hole aperture
And the semicircular lid pin-and-hole opposite disposed with it, described rotary table main body is fixing with described upper cover body to be connected, described revolution
The two ends of platform pin-and-hole are provided with main body boss, and the two ends of described lid pin-and-hole are provided with lid boss, and described main body boss is around revolution
The excircle of platform pin-and-hole is arranged, and described lid boss is arranged around the excircle of lid pin-and-hole, and the middle part of described big end cap is provided with
The cylindrical recess mated with rotary table pin-and-hole and lid boss, described recess is buckled in described main body boss and described lid is convex
On platform.
In this technical scheme, by monoblock type rotary table of the prior art is changed into split type, when installment work mechanism,
Directly the bearing pin that operating mechanism two ends connect can be fallen in rotary table body pin, then upper cover body is fixed on rotary table main body
On, can quickly realize being assembled with of operating mechanism；When dismounting and maintenance, first upper cover body is separated with rotary table main body,
Operating mechanism just can directly remove from rotary table main body, the most convenient with regard to the dismounting of Neng Shi operating mechanism and maintenance process
?；By making main body boss and lid boss arrange along the excircle of pin-and-hole, then make it by the big end cap with recess
Link together, so can offset the shearing force that the junction of split type rotary table is produced because of revolution action by operating mechanism,
It is thus possible to make split type rotary table have more preferable load bearing stength to operating mechanism, alternatively, it is also possible to increase upper cover body with
The contact area of rotary table main body, so can increase the fixing intensity between upper cover body and rotary table main body, so that upper cover
Body is more firm with the connection of rotary table main body.
Further, described rotary table main body and upper cover body are equipped with keyway on contact surface opposite each other, in described keyway
It is provided with keypad.
In this technical scheme, by being provided with keyway on the contact surface of rotary table main body and upper cover body, and keypad is placed in
In keyway, can effectively prevent the relative slip between upper cover body with rotary table main body, upper cover can be offset further simultaneously
The shearing force that junction between body and rotary table main body produces because of revolution action such that it is able to make split type rotary table to work
That makees mechanism has more preferable load bearing stength.
Further, described keypad is connected by bolt and the keyway in rotary table main body are fixing.
In this technical scheme, by making keypad be fixed in keyway, it is possible to prevent keypad relative to rotary table main body or upper cover
The slip of body, thus facilitate the assembling of operating mechanism, during also ensuring that work or assembling, keypad will not drop simultaneously.
Further, the two ends of described upper cover body and rotary table main body are provided with bolt hole, and described big end cap passes through bolt with upper
Lid and the fixing connection of rotary table main body.
In this technical scheme, it is connected fixing with main body boss and lid boss for big end cap by bolt, it is possible to add further
Strong upper cover body and the bonding strength of rotary table main body.
Further, described upper cover body is being provided with bolt hole with rotary table body contact end, and bolt passes through lock washer by upper cover body
It is fixedly connected in rotary table main body.
In this technical scheme, by the contact jaw of upper cover body with rotary table main body being connected with lock washer with clamping screw,
Upper cover body can be facilitated to separate with rotary table main body.
Further, described big end cap is provided with circular hole at the center away from main body boss side, sets uniformly in described circular
Having screwed hole, the small cover adaptive with described circular hole is connected by bolt and big end cap are fixing.
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 is in the case of rotary table main body and pivoting support connected mode are constant, by monoblock type rotary table
It is divided into upper cover body and rotary table main body two parts such that it is able to realize the Assembly And Disassembly of rotary table and operating mechanism efficiently,
By the design of boss Yu big end cap, split type rotary table can be made operating mechanism to have more preferable load bearing stength, simultaneously energy
The shearing force that split type rotary table junction is produced by enough effectively counteracting operating mechanisms when revolution action.
