the Chinese patent being CN202121238U as publication number discloses a kind of handcart position locking device, it comprises front beam, support, guide rail, driver plate and arm-tie, described support is vertical with front beam and be fixedly connected with, described guide rail is fixed on side cabinet, described arm-tie is arranged on guide rail, and can move forward and backward relative to guide rail, described arm-tie is connected with driver plate, and described driver plate can move forward and backward with arm-tie simultaneously.Handcart can only be locked in a position by this kind of handcart position locking device, and the structure of locking device also more complicated, operates also more loaded down with trivial details.
Summary of the invention
the utility model object is: provide a kind of handcart locking device, handcart can be locked in test position or service position, and structure is simple, and locking is reliable, can ensure the safety of operating personnel.
the technical solution of the utility model is:
a kind of handcart locking device, comprise the rotating shaft that one end is connected with tapered end, the other end of described rotating shaft is provided with the rotation section that can rotate around the axis and for being fixed on the fixed block on handcart room base plate, described rotating shaft is provided with the spring pivot that rotation section can be made to rotate, described rotation section is connected with lock shaft, described lock shaft periphery is provided with sleeve, and described handcart chassis is provided with the lockhole coordinated with lock shaft.
further, described rotation section comprises the two panels connecting rod be arranged in rotating shaft, described two panels connecting rod is fixed by fixed axis, the second fixed axis that described fixed axis comprises the first fixed axis and is connected with lock shaft, and described first fixed axis is arranged on the inner side of two panels connecting rod and crossing with spring pivot.
further, described fixed block is a bent plate, offers fixing hole at the kink of bent plate.
further, described lockhole is provided with two, and two lockholes are arranged on and the diverse location on rotating shaft one straight line.
further, described bent plate and handcart room base plate are fixed by rivet, and described sleeve is fixed by nut and handcart room base plate.
the utility model has the advantages that:
handcart can be locked in test position and service position by this locking device, and structure is simple, and locking is reliable, can ensure the safety of operating personnel, prevent hot line job.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the structural representation of the utility model handcart locking device;
fig. 2 is the partial enlarged drawing of Fig. 1;
fig. 3 is the utility model handcart locking device and handcart room scheme of installation.
wherein: 1, tapered end, 2, rotating shaft, 3, connecting rod, 4, spring pivot, 5, bent plate, the 6, first fixed axis, the 7, second fixed axis, 8, back-up ring, 9, chute, 10, lock shaft, 11, handcart room base plate, 12, the front beam of handcart room plate, 13, nut, 14, sleeve.
Embodiment
for making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
embodiment:
as Figure 1-3, a kind of handcart locking device, tapered end 1 is arranged on the front beam 12 of handcart room plate, the rotating shaft 2 that one end is connected with tapered end 1, the other end of rotating shaft 1 is provided with can the 1 two panels connecting rod 3 rotated and bent plate 5 around the shaft, connecting rod 3 is by the first fixed axis 6, second fixed axis 7 is fixedly connected with 4 back-up rings 8, rotating shaft 1 in the middle of two panels connecting rod 3 is provided with the spring pivot 4 crossing with the first fixed axis 6, first fixed axis 6 is arranged on the inner side of connecting rod 3, the outside that second fixed axis 7 is arranged on connecting rod 3 is connected with lock shaft 10, outside lock shaft 10, cover has sleeve 14, sleeve 14 lower end is provided with the chute 9 that can slide for the second fixed axis 7, bent plate 5 and handcart room base plate 11 are fixed by rivet, sleeve 14 is fixed by nut 13 and handcart room base plate 11, handcart chassis is provided with the lockhole coordinated with lock shaft 10.Lockhole is provided with two, and two lockholes are arranged on and the diverse location on rotating shaft 2 one straight line.
with key dextrorotation rotation cores, spring pivot 4 on rotating shaft 1 and axle is driven to rotate, the first fixed axis 6 that spring pivot 4 stirs inner side rotates, respective link 3 and outside second fixed axis 7 rotate clockwise, second fixed axis 7 promotes lock shaft 10 straight line and moves upward and stretch out sleeve 14, and inserts in the lockhole on handcart chassis.Like this handcart is locked in corresponding position.Key can take off in this position.Unlock, be rotated counterclockwise key, spring pivot 4 no longer blocks the first fixed axis 6, second fixed axis 7, connecting rod 3, lock shaft 10 down fall after rise under the gravity of self, lock shaft 10 exits just now inserted hole, unlocks.
the requirement that mid-hands injured handcart needs are locked in test position or service position can be met.As mother, a key locked by breaker cabinet and isolation cabinet two.Requirement is accomplished to prevent charged drawing from isolating handcart.Breaker cabinet circuit breaker cart is locked in test position, takes off key, inserts isolation cabinet lock, handcart is former is locked in service position in isolation, be retracted to test position, but key can not be taken down after now could unlocking, and circuit breaker cart can not unlock from test position, people service position can not be pushed away.Work after locking position until isolation handcart pushes away people, can key be taken down, then to breaker cabinet, after the test position that circuit breaker cart is locked in is unlocked, circuit breaker cart can push away people to service position.Now key can not be taken down, and can not unlock isolation handcart, namely charged pull-out can not isolate handcart to test position.
should be understood that, above-mentioned embodiment of the present utility model only for exemplary illustration or explain principle of the present utility model, and is not formed restriction of the present utility model.Therefore, any amendment made when not departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.In addition, the utility model claims be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
