The specific embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
In description of the present utility model, it should be noted that, term " " center ", " longitudinally ", " laterally ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of indications such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, rather than device or the element of indication or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as restriction of the present utility model.Unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection ", " fixing " should be interpreted broadly, and for example, can be to be fixedly connected with, and can be also to removably connect, or connect integratedly; Can be mechanical connection, can be to be also electrically connected to; Can be to be directly connected, also can indirectly be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, can concrete condition understand the concrete meaning of above-mentioned term in the utility model.In addition,, in description of the present utility model, except as otherwise noted, the implication of " a plurality of " is two or more.
As shown in Figure 1, the sliding-type cable shrinkage device of the present embodiment comprises: baffle plate 1, approach switch 2, fixed support 3, steel wire rope 4, communication cable 5, leader cable 6, sliding machine 7, trolley track 8 and head pulley 9.
Sliding machine 7 is a plurality of, sliding machine 7 is connected and can be free to slide along trolley track 8 with trolley track 8, head pulley 9 is located near the outlet (being the right-hand member of trolley track 8 in Fig. 1) of trolley track 8, head pulley 9 draws whole sliding-type cable shrinkage device for plant equipment, plant equipment comes and goes traction head pulley 9 and comes and goes operation, thereby drive leader cable 6 and sliding machine 7 motions, cable leader cable 6 hangs on a plurality of sliding machines 7 and head pulley 9, by a plurality of sliding machines 7 and head pulley 9, hang on trolley track 8, one end of leader cable 6 is connected with power supply, the other end is connected with the field control cabinet 10 of corresponding plant equipment, leader cable 6 can be with respect to trolley track 8 contraction of sliding by sliding machine 7 and head pulley 9, movement or walking with the field control cabinet 10 of cooperative mechanical equipment.
Baffle plate 1 is located near the end of the point of incoming cables (being the left end of trolley track 8 in Fig. 1) of trolley track 8, approach switch 2 is fixed on the point of incoming cables of trolley track 8 by fixed support 3, baffle plate 1 is the matching component of approach switch 2, for forming the field control cabinet 10 that loop signal reaches plant equipment, approach switch 2 is connected with the field control cabinet 10 of plant equipment by communication cable 5, communication cable 5 and steel wire rope 4 hang on sliding machine 7 and head pulley 9 together with leader cable 6, the length that is shorter in length than leader cable 6 of communication cable 5, the length that is shorter in length than communication cable 5 of steel wire rope 4.Approach switch 2 and communication cable 5 have formed a signal pickup assembly jointly, this signal pickup assembly is connected with the field control cabinet 10 of plant equipment, in the PLC of field control cabinet 10 that the signal condition of approach switch 2 directly feeds back to plant equipment by communication cable 5, so, the signal condition of approach switch 2 feedbacks that the field control cabinet 10 by plant equipment receives, just can judge the break-make situation of communication cable 5.
Relevant machinery equipment comes and goes in running on trapped orbit, leader cable 6 retinues come and go contraction, steel wire rope 4 plays traction leader cable 6 and leader cable 6 is played to elementary defencive function in whole round contraction process, but can only protect the leader cable 6 in the situation that steel wire rope 4 is intact, communication cable 5, before steel wire rope 4 is not broken, there will not be fault to cause approach switch 2 signal intensities, and above-mentioned approach switch 2 and communication cable 5 the another pipe protection after can making up steel wire rope 4 and being pulled off is set, thereby avoid further destruction, generally that break-make by communication cable 5 plays a protective role to leader cable 6, field control cabinet 10 from baffle plate 1 to plant equipment, as long as after steel wire rope 4 is broken, when being corrupted to communication cable 5, the signal of approach switch 2 changes, the PLC of the field control cabinet 10 of plant equipment can make protection action at once, cut away run signal, thereby make relevant plant equipment automatically protect shutdown, avoid fault further to cause chain destruction.In the slip contraction process of cable, any one communication cable 5 occurs abnormal, and relevant plant equipment will be protected shutdown automatically; simultaneously; fault-signal can be sent to central control room, operator on duty also can receive failure condition the very first time, and then goes to scene to check immediately; check all sliding machines 7 place of breaking down; process or change bearing, finally at connecting communication cable 5, resetting system; can reopen equipment, produce.The chain destruction impact that the automatic protection of this device causes fault is reduced to minimum.
The baffle plate that the difference injection of the sliding-type cable shrinkage device of the present embodiment and conventional cable slide wire structure is to set up, approach switch, fixing between and communication cable etc., and the concrete structure of other parts, as: the structure of sliding machine, the structure of trolley track, sliding machine and the matching relationship of trolley track are, the arrangement of leader cable etc., be conventional version, repeat no more herein.
The sliding-type cable shrinkage device of the present embodiment can be for walking mud scraper, be that leader cable is connected with the field control cabinet of the associated machines of walking mud scraper, certainly, this sliding-type cable shrinkage device also can be in other similar plant equipment.
Sliding-type cable shrinkage device of the present utility model is connected approach switch by being shorter than the communication cable of leader cable with the field control cabinet of plant equipment, while there is the phenomenons such as the stuck or walking roller derailing of bearing in plant equipment, communication cable can rupture prior to leader cable, the signal that makes approach switch send the field control cabinet of large plant equipment changes, thereby very first time protection shutdown automatically after plant equipment can be broken down in unattended situation, avoided leader cable, the chain destruction of pulley and guide rail etc., guaranteed the safety in production of plant equipment, this sliding-type cable shrinkage device of the present utility model, simple and reasonable, with low cost, there is very strong versatility, be easy to batch production and promote the use of.
Embodiment of the present utility model provides for example with for the purpose of describing, and is not exhaustively or by the utility model to be limited to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present utility model and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiment with various modifications that the utility model design is suitable for special-purpose.
