Traditional Placement, be generally that front-end face or side flange connect, this form structure is fairly simple, but its moment of torsion born can be transformed into pulling force on bolt or shearing force, and this structure anti-twisting property is more weak, and connection interface is not easily expanded; Adopt square plate interface to resist the Connecting format of moment of torsion, can transfer torque on square structure, instead of on bolt, its antitorque characteristic will be considerably increased like this, and this structure, in conjunction with side flange structure, effectively resists lateral force, there is good stability.At present, the square polygonal transmission shaft that is connected to has application, mainly provides larger moment of torsion, but square plate does not occur as large-scale heavy duty mechanism Connecting format in conjunction with the Connecting format of side flange.And traditional end face Placement is just for specific linkage structure, and square plate Connecting format has very strong versatility, can be mutually general in various mechanism, the breakdown loss of machinery greatly can be reduced.Design a kind of torque resistant and all very strong unitized Connecting format of stability, be a kind of effective means improving work efficiency of machine and quality, and be necessary.
Summary of the invention
The shortcoming of high torque resistant and high stability can not be taken into account to overcome traditional Connecting format, the invention provides a kind of high antitorque, high stability, high unitized new Joining Structure.
The technical solution adopted for the present invention to solve the technical problems is (illustrating for the cutting portion of LMGC-800 hydraulic open-air coal winning machine):
The antitorque linkage structure of height of heavy loading mechanism, be arranged on be connected to each other between the first mechanism and the second mechanism, it is characterized in that: the side of the-the first mechanism connects the second mechanism by square plate linkage structure; The square mounting disc that described square plate linkage structure comprises the side being cemented in the first described mechanism and the side flange be arranged on around described square mounting disc, the second described organization establishes has square groove, and type of the carving chamfering being convenient to described square mounting disc be included in described square groove is arranged at the top of described square mounting disc; Described side flange is connected by screw the second described mechanism;
The backend arrangement of the first described mechanism can the end flanges of driver module; There are the inner chamber and through hole that pass through for transmission shaft or pipeline in the first described mechanism.
The present invention is the comprehensive Placement of square mounting structure (side have carve type chamfering structure), side flange linkage structure and rearmounted development method flange connection structure etc.Square linkage structure is quadrilateral structure, and be convenient to processing, side has carves type chamfering, exactly by square groove that square structure alignment machine connects with it when being convenient to install; Side flange connects, and connect and adopt screw-type, save very large space, centre leaves the space that transmission shaft, pipeline etc. pass through; After adopting side form to install, the face, rear flank of heavy loading mechanism attachment portion arranges expansion flange arrangement, is a kind of Redundancy Design, facilitates motor, the installation and removal of hydraulic module equal power device, exchanges provide possibility for cutting portion electric drive and hydraulic driving.
Beneficial effect of the present invention is mainly manifested in: Connecting format adopts square structure, and anti-twisting property is larger; Square structure end adds carves type chamfering, and is that side is installed, and total is installed and carries out than being easier to; Installing fixed form is that flange coordinates square structure to install, and dismantles more convenient, is convenient to modularization and the generalization of mounting structure; Adopt the mode that side connects, can design rearmounted flange like this as general extension mounting interface, facilitate the installation of other structures such as motor, hydraulic module, this is Redundancy Design, considerably increases the generalization of Connecting format.

Embodiment
With reference to accompanying drawing 1-5:
The antitorque linkage structure of height of heavy loading mechanism, be arranged on be connected to each other between the first mechanism and the second mechanism, it is characterized in that: Gu the side of the first mechanism connects the second mechanism by square plate linkage structure; The square mounting disc that described square plate linkage structure comprises the side being cemented in the first described mechanism and the side flange be arranged on around described square mounting disc, the second described organization establishes has square groove, and type of the carving chamfering being convenient to described square mounting disc be included in described square groove is arranged at the top of described square mounting disc; Described side flange is connected by screw the second described mechanism;
The backend arrangement of the first described mechanism can install the end flanges of driver module; There are the inner chamber and through hole that pass through for transmission shaft or pipeline in the first described mechanism.
In the operation mechanism of drum-type open coal winning machine, be applied as example with this novel mounting structure below, the invention will be further described by reference to the accompanying drawings.
This novel mounting structure is arranged on by square mounting disc 3 above the square mounting groove 10 on coal winning machine forearm, is then closely being fixed total with bolt by side flange 2, reaches high antitorque and high stability two project.This mounting structure is hollow structure, through hole is left in front and back, rear side is designed to general end flanges 1, hydraulic installalion block 7 can be installed, also can mounted motor mounting blocks 9, the cylinder that power can be passed to coal winning machine by the front and back through hole 5 of new structure by hydraulic pipe line 6 and motor transmission shaft 8 carries out coal cutting work.
Square mounting disc 3 is that square ways is installed with the installation of mounting groove 10, and such born moment of torsion all can be transformed in square mounting disc, makes anti-twisting property more antitorque than simple bolt much bigger like this.Square installation wants to realize reasonable tangential stability, just necessarily requires square structure to have relatively high machining accuracy, and the high difficulty that will increase installation assembling of machining accuracy.For this reason, carving angle at the end face of square mounting structure, by carving the leading role of type structure 4 during installation, easily square mounting disc 3 being loaded square mounting groove 10.Due to employing is side installation form, and this structure also exists axial stability problem, and for this reason, we devise side flange 2 on square mounting disc side and are connected with forearm, and total will be made like this to have very strong stability.Rearmounted end flanges 1 is more common, adapts to the installation module (mainly hydraulic driving and motor drive two large forms) of different driving form, mounts and dismounts all more convenient.Square mounting disc 3 and rearmounted end flanges 1, all more commonization, as a kind of general heavy loading mechanism mounting structure, can have high resistance to torsion and high stability simultaneously.
