Abstract
A lifting mechanism with a coiling drum locking device relates to the hoisting machinery. The invention overcomes the problem that the prior lifting mechanism can not move a gear change hand lever to realize speed change even in the state of idle load; moreover, parts can not be replaced or examined and repaired. The lifting mechanism comprises a coiling drum of which the coiling drum locking device is arranged beside a bearing seat. The coiling drum locking device includes a lower pedestal, an upper pedestal, a locking shaft, a hand lever and a limit switch, wherein the lower pedestal is fixed on a moving trolley frame, the upper pedestal is connected with the lower pedestal by a bolt, a shaft hole for the locking shaft inserted is machined above the upper pedestal, a long shaft hole is also arranged on a side support plate of the coiling drum corresponding to the shaft hole position of the upper pedestal, the hand lever is arranged on the outer end of the locking shaft and the limit switch is fixed on the lower pedestal under the hand lever. The invention not only improves the security of the crane, but also facilitates the operation in site, and improves the use efficiency of the mechanism.
Description
Technical field
The present invention relates to elevator machinery, particularly a kind of (elevator) mechanism that hoists.
Background technology
Existing hoisting (elevator) mechanism is made up of reel 2, retarder 3, drg 5, coupler 6, electrical motor 7, suspender 1 and steel rope 9 as shown in Figure 1.Electrical motor 7 links to each other with retarder 3 by coupler 6, and suspender 1, reel 2 twine by steel rope 9 and be bound up, and drives reel 2 during the electrical motor energising and rotates, and finishes the operation that hoists by suspender 1.In order to improve the operating efficiency that hoists, on retarder 3, be provided with variable gear, come displacement with gear change hand lever 4.When suspender is suspended in when aerial because the effect of suspender and steel rope, if counter the dragging or the braking of drg 5 that does not have an electrical motor 7, though suspender not bringing onto load also can descend the poor stability of equipment.Existing hoisting (elevator) mechanism is even suspender also can't come speed change by mobile gear change hand lever under light condition; Also can't change or overhaul drg, electrical motor, coupler, use inconvenient.
Summary of the invention
Purpose of the present invention is intended to overcome the shortcoming of prior art, a kind of lifting mechanism that has drum locking device is provided, the any position of suspender under light condition, parts such as motor, drg, coupler can be overhauled safe and conveniently or change to gear change hand lever speed change that can mobile retarder.
The present invention is achieved through the following technical solutions:
A kind of lifting mechanism that has drum locking device, described lifting mechanism comprises: reel, retarder, coupler, electrical motor, suspender and steel rope, described electrical motor links to each other with described retarder by described coupler, and drive described reel and rotate, described reel is connected with described suspender by described steel rope, it is characterized in that: the described drum locking device of the other installation of the bearing seat of described reel, described drum locking device comprises: undersetting, upper bracket, lock shaft, handle, limit switch, described undersetting is fixed on the running trolley frame, described upper bracket and described undersetting bolt together, being processed with above described upper bracket can be for described lock shaft insertion axis hole wherein, also be provided with the major axis hole at described reel lateral bolster board corresponding to the axis hole position of described upper bracket, be provided with described handle in the outer end of described lock shaft, be provided with the described limit switch that is fixed on the described undersetting below the described handle.The middle part of described lock shaft is provided with the guide-localization key.
The present invention compared with prior art, owing on the basis of existing (elevator) mechanism that hoists, increased the blocking device of reel, therefore, the any position of suspender under light condition, parts such as motor, drg, coupler, the safety that has not only improved equipment can be overhauled or change to gear change hand lever speed change that can mobile retarder, and made things convenient for on-the-spot operation, improved production efficiency.
