Abstract
The invention provides a locking device; and the locking device comprises a locked piece, a supporting seat, a driver, a bolt and a connecting rod, wherein a locating hole is formed in the locked piece; the driver is arranged on the supporting seat; two ends of the connecting rod are respectively hinged on the driver and the bolt; and when the driver is started, the connecting rod is driven to rotate around the supporting seat, so that the bolt is driven to be inserted into and withdrawn from the locating hole. The locking device provided by the invention has the advantages as follows: the locked piece is fixed through inserting the bolt into the locating hole of the locked piece, so that the locked piece is prevented from being inclined and safety accidents are reduced.
Description
Technical field
The present invention and a kind of elevating platform relate in particular to a kind of blocking device of elevating platform.
Background technology
The chief component of jacking system is the spud leg of workplatform, support platform and the engine installation of control workbench lifting.Be provided with pinion rack on the workplatform, be provided with lifter rack on the spud leg.Engine installation is in order to drive pinion rack with the lifter rack engagement or to separate.After jacking system arrived new operating location, when needing to adjust the relative position of workplatform and spud leg, pinion rack separated with lifter rack, after adjusting the height of spud leg, restart engine installation, drive the engagement of pinion rack and lifter rack, thereby adjust the relative position of workplatform and spud leg.
Yet, in the process of the relative position of adjusting workplatform and spud leg, find that pinion rack can tilt to lifter rack, safety misadventure easily occurs.
Summary of the invention
In view of this, be necessary to provide a kind of blocking device that safety misadventure occurs that reduces.
A kind of lockout mechanism comprises locked, supporting base, actuator, latch and connecting rod; Offer knock hole on described locked, described actuator is arranged on the described supporting base, and described connecting rod two ends are articulated in respectively on described actuator and the described latch; When described actuator starts, drive described connecting rod and rotate around described supporting base, insert and withdraw from described knock hole thereby drive described latch.
Described actuator is fluid cylinder.
The flexible direction of described actuator is vertical with the moving direction of described latch.
One end of described actuator offers the first waist shaped hole, and an end of described latch offers the second waist shaped hole, and the two ends of described connecting rod are articulated in respectively in described the first waist shaped hole and the second waist shaped hole.
Be provided with guide holder on the described supporting base, described latch is arranged on the described guide holder actively.
Offer guide groove on the described guide holder, described latch is arranged in the described guide groove actively.
Described connecting rod is L-type.
Described locked comprises connecting element and the pinion rack that is fixed on the described connecting element, and described knock hole is opened on the described connecting element.
Above-mentioned blocking device inserts latch by the knock hole to locked, thereby fixing locked, avoid locked inclination, thus the generation of decrease safent accident.
Description of drawings
Fig. 1 is the schematic diagram of a preferred embodiment blocking device.
Fig. 2 is the schematic diagram of blocking device lock-out state among Fig. 1.
Specific embodiment
As shown in Figure 1, be the schematic diagram of a preferred embodiment blocking device 50.Blocking device 50 comprises locked 51, supporting base 53, lock drive device 55, latch 57 and connecting rod 59.
Supporting base 53 is used for carrying lock drive device 55, latch 57 and connecting rod 59.Supporting base 53 is provided with guide holder 532, offers guide groove 531 on the guide holder 532.
The cylinder body 551 of lock drive device 55 is fixed on the supporting base 53, and the piston rod 553 of lock drive device 55 is articulated on the connecting rod 59.In the present embodiment, lock drive device 55 is fluid cylinder.One end of lock drive mechanism 55 offers the first waist shaped hole 555, so that be connected with connecting rod 59.
Connecting rod 59 is roughly L-type, and the one end is articulated in first waist shaped hole 555 of piston rod 553 of lock drive device 55, and the other end is articulated in the second waist shaped hole 571 of latch 57, and the middle part is articulated on the supporting base 53.
See also Fig. 2, when lock drive device 55 started, drivening rod 59 rotated around supporting base 53, thereby drove latch 57 in guide groove 531 interior movements, thereby so that latch 57 withdraw from or insert in the knock hole 515.Because the two ends of connecting rod 59 are in the time of latch 57 and 55 rotation of lock drive device, meeting is in the first waist shaped hole 571 and the 551 interior movements of the second waist shaped hole, thereby so that the flexible direction of lock drive device 55 is vertical with the moving direction of latch 57.In the present embodiment, lock drive device 55 is fluid cylinder.
When jacking system need to be adjusted relative position between platform support and the spud leg, start lock drive device 55, drivening rod 59 rotates around supporting base 53, thereby drives latch 57 in guide groove 531 interior movements, thereby so that latch 57 insert in the knock holees 515; When treating that the spud leg adjustment is finished, start lock drive device 55, drivening rod 59 rotates around supporting base 53, thereby drives latch 57 in guide groove 531 interior movements, thereby so that latch 57 withdraws from knock hole 515, pinion rack 511 just can mesh with spud leg.
Above-mentioned blocking device 50 is in the relative position process of adjusting platform support and spud leg, by latch 57 insertions of lockout mechanism 50 are fixed on the knock hole 515 of the connecting element 513 on the pinion rack 511, thereby fixed engagement tooth bar 511, avoid pinion rack 511 to tilt to lifter rack, thus the generation of decrease safent accident.
