Description

Door machine Gearbox jettison gear

Technical field

The utility model relates to high pedestal jib crane reduction gearbox maintenance technology fields, especially belong to a kind of door machine reduction gearbox The jettison gear of cabinet.

Background technique

The maintenance of existing high pedestal jib crane reduction gearbox every two years needs to change a gear oil.It needs before changing oil by subtracting Drain oil in the middle part of fast case puts it clean the old gear oil in reduction gearbox, then pours into clean gear oil enters.Since this is put Oilhole is located in the middle part of reduction gearbox, and Gearbox is in the steel construction box house of door machine computer room, therefore needs first to tear open before draining the oil Except rotating electric machine, the fastening bolt of reduction gearbox is unclamped, reduction gearbox is hung to ground with crane or jack cooperation or by reduction gearbox It slings until leaking out the position of drain oil, completion is changed oil after operation, and reduction gearbox is transferred to original position, fastening bolt, installation rotation Rotating motor.Reduction gearbox replaces a gear oil, and lifting appliance is needed to cooperate, and repeated removal installs work step, and several maintenance personnel operate, Working efficiency is extremely low.

Summary of the invention

The purpose of this utility model seeks to provide a kind of door machine Gearbox jettison gear, to reach simplified reduction gearbox Oil drain operation improves working efficiency, saves equipment, the purpose of labour cost.

The door machine Gearbox jettison gear of the utility model, including the drain oil in Gearbox, feature exists In there is the connector closely coupled with the drain oil, the petroleum pipeline being connected with connector tail end, the petroleum pipeline is from reduction gearbox case It draws in vivo, petroleum pipeline exit is equipped with hand-operated valve.

The door machine Gearbox jettison gear of the utility model, drain oil is connected with petroleum pipeline, is drawn by petroleum pipeline To outside the cabinet of door machine computer room, reduction gearbox, which is drained the oil, to no longer need to be answered using lifting appliance and several maintenance personnel's compounding practices Miscellaneous installing and dismounting work, need to only unscrew the hand-operated valve of oil transportation pipe end, can easily put the old gear oil in reduction gearbox Out, there is time saving and energy saving, reduction maintenance cost, practical good effect.

Detailed description of the invention

Fig. 1 is the operation schematic diagram of the utility model door machine Gearbox jettison gear.

Specific embodiment

As shown in Figure 1, the door machine Gearbox jettison gear of the utility model, including draining the oil in Gearbox 1 Hole 2, the drain oil 2 are in the steel construction box house of door machine computer room.Connector 4 and the drain oil 2 are closely coupled, connector 4 Tail end sealing is connected with petroleum pipeline 5, and petroleum pipeline 5 is led to from Gearbox 1 outside door machine computer room steel-structure box body, convenient The height of maintenance personnel's operation, 5 exit of petroleum pipeline are equipped with hand-operated valve 6.Due to the Gearbox 1 of high pedestal jib crane Positioned at the steel construction box house of door machine computer room, former reduction gearbox is drained the oil after first the rotating electric machine 3 of front end need to be dismantled, and slings deceleration Box body 1 exposes drain oil 2 and drains the oil, and needs several operators to cooperate and completes, time-consuming and laborious, working efficiency is low.The present apparatus is installed Afterwards, when rotating reduction gearbox Oil drain operation to door machine, only an operator is needed to unscrew the hand-operated valve 6 of 5 end of petroleum pipeline, slowed down Old gear oil in box body 1 can be flowed out from drain oil 2 through petroleum pipeline 5, until putting it clean old gear oil, close hand Dynamic valve 6.Cooperate jointly without lifting appliance and several operators, has saved equipment and personnel cost, be easily accomplished reduction gearbox The old gear oil Oil drain operation of cabinet 1.

Present apparatus structure is simple, can be transformed to existing door machine Gearbox, improvement cost expense is low, practicability By force, obvious economic.
