Abstract
The utility model relates to a safety cut-out fuse of a shearing-type lifter, which is an improved safety cut-out fuse of a shearing-type lifter. The utility model solves the defects of unsafety, big volume and high area-occupying cost of an original safety cut-out fuse with a structure of double racks. The utility model is composed of a cylinder body, a plunger, a pressing spring, a cylinder cap, a lock, a tooth clamp and a connection shaft. The utility model has the advantages that the safety cut-out fuse of the shearing-type lifter is fixed on the shear-typing lifter, and the tooth clamp contacts a rack tooth on the lifter all the time; thus, the safety state is kept at any moment; thereby, the lifting process is safe, and accident of personnel injury can not occur. The safety cut-out fuse of the utility model substitutes the traditional safety structure with double tooth clamps, and reduces the installation cost of the embedded area because the utility model has a small volume. The utility model can also be installed on the ground, so the occupied space of the utility model is small.
Description
Technical field: the invention relates to the improvement of the safety locking motion structure of shearing type lifter, and this device is to play the security insurance effect on shearing type lifter.
Background technology: at present, the shearing type lifter safety locking motion all adopts the double rack structure both at home and abroad, be in operation and demonstrate its deficiency: the one, when lifting, the upper rack of safety locking motion must lift before operation starts, in the lifting process, upper rack is in the state of lifting all the time, in case meet accident in the lifting process, the lifting machine will glide suddenly, and safety device does not play safety effect, the personnel that cause easily injure, and the 2nd, the double rack structure, size is bigger, so hide ground erected cost height, as installing and using on the ground, take up room and big, bring inconvenience to use.
Summary of the invention: the purpose of the invention provides a kind of shearing type lifter that is used for, and plays the shearing type lifter safety locking motion of safety effect during lifting; The purpose of the invention is achieved through the following technical solutions: the shearing type lifter safety locking motion, it is characterized in that: the shearing type lifter safety locking motion is made of cylinder body, piston, stage clip, cylinder cap, tapered end, tooth card, adapter shaft, piston is installed in the cylinder body, compression spring sleeve is contained on the piston, the cylinder cap is installed on the cylinder body termination, tapered end is installed on the piston termination, and tapered end is by adapter shaft and tooth card connection.
The advantage of the invention: owing to adopted the tooth mechanism for card, tooth is stuck under the combined action of cylinder body, piston, tapered end, the tooth card is contacted with the tooth bar of lifting machine all the time, during the lifting of lifting machine, piston rod drives tooth bar and moves up, and the tooth card is in the stuck state that contacts all the time with tooth on the tooth bar, can not take place because of burst accident, the lifting machine is glided suddenly, avoid personnel to injure, played the security insurance effect; Owing to adopt this safety locking motion, the lifting machine is saved a tooth bar, and smaller volume can reduce device height, saves and hides the ground erected cost, also can floor mounted use.
Description of drawings:
Fig. 1 installs shearing type lifter safety locking motion structural representation;
Fig. 2 is an I enlarged drawing among Fig. 1;
Fig. 3 is a shearing type lifter safety locking motion structural representation of not being with the tooth card.
The specific embodiment: shearing type lifter safety locking motion: by cylinder body 4, piston 2, stage clip 5, cylinder cap 3, tapered end 1, tooth card 9, adapter shaft 6 constitutes, cylinder body 4 is made the inner-cavity structure of an end opening, make induction opening at intracavity bottom, make the installation through hole at the closed end of cylinder body 4, open end is made outside thread, cylinder cap 3 is shaped on negative thread, tapered end 1 is made and piston 2 bonded assembly holes, with with adapter shaft 6 bonded assembly holes, tooth card 9 is made trapezoidal, make on it and adapter shaft 6 bonded assembly hole and mounting holes, piston 2 is contained in the cylinder body 4, stage clip 5 is sleeved on the piston 2, cylinder cap 3 is screwedly mounted on the cylinder body 4, tapered end 1 is installed on the termination of piston 2, tooth card 9 is connected with tapered end 1 by adapter shaft 6, the shearing type lifter safety locking motion that is assembled into is fixed on the shearing type lifter, fix by installation through hole on the cylinder body 4 and mounting hole and the shearing type lifter on the tooth card 9, the tooth bar 7 that piston rod 8 after the lifting of lifting machine starts on the lifting machine drives on the lifting machine moves up, tooth on the tooth bar 7 and tooth card 9 are in moving contact, tooth of every slip just sends click, the operator can be directly perceived, can judge from sound also whether safety locking motion is working properly, safety locking motion always is in the safety effect state that plays in shearing type lifter lifting process, the lifting machine phenomenon that glides suddenly can not appear, avoided personnel's injury in operating process, this safety locking motion substitutes the double rack safety structure, and volume is little, save erected cost, the convenient use.When the lifting machine descended, pressurized air entered cylinder body from bottom inflow hole, chamber, and piston stretches out, and compression press spring promotes the swing of tooth card cw, disengages with tooth bar, and the lifting machine begins to descend.
