Abstract
The utility model discloses an installation apparatus for a gate machine walking gear box, which is provided in order to overcome the defects that members of a gear box and a transmission gear of the walking part of the existing installation gate machine are easy to damnify caused by hammer knocking, the operation is unsafe and efficiency is low. A screw rod is sheathed with a screw nut, wherein one side of the screw nut can be supported on the outer side surface of a housing of the gear box of the walking part to turn and one end of the screw rod can be screwed in a screw hole of a gate machine walking transmission shaft head. Because one end of the screw rod is screwed in the screw hole of the transmission shaft head, the screw nut screwed on the screw rod is supported on the outer side surface of the housing of the gear box through a plane bearing, the screw nut turns, the transmission gear in the gear box is extruded on a transmission shaft smoothly under the condition that the screw rod does not move and the gear box is driven to move to a proper installation position. Vibration does not exist, press is uniform, the shaft head is not damnified, persons can not be injured and are safe, operation is simple and efficiency can be improved by two times.
Description
Technical field
The invention belongs to erecting tools, specifically a kind of erecting tools that is used for large-scale lifting with door machine traction gear box.
Background technology
The large-scale lifting that port and pier are used a door machine, the power transmission shaft of its running gear stretches in the gearbox, because power transmission shaft is thicker and the installation site is special not quick detachable, be that gearbox and interior gear thereof are disassembled during general repair, after the repairing casing and interior travelling gear thereof be installed on the power transmission shaft.Existing gearbox and interior gear mounting means thereof, be with case and interior gear hole thereof at the transmission spindle nose, the pad copper rod installation that pounds with a hammer on gear.The shortcoming of said method is, huge impact power can produce vibration tempestuously, and parts impacted cause damage easily, and it is unbalanced that the palm of choosing is simultaneously held the strength that hammer knocks, in case beat less than on the central point, one side is damaged spindle nose; Impetus is not just also beaten copper rod easily and is flown to hurt sb.'s feelings on the other hand, be absolutely unsafe, and inefficiency.
The utility model content
Technical problem to be solved in the utility model is, overcomes the existing door machine traction gear box of installing, and the easy defective component that pounds with a hammer and dangerous, inefficient shortcoming provide a kind of machine walking gearbox erector.
In order to solve the problems referred to above that prior art exists, the technical solution of the utility model is: at one end can be screwed on the leading screw in the machine walking transmission spindle nose screw, be with the one side and can withstand on the nut that rotates on the traction gear box shell lateral surface.
The utility model also has following feature:
The described nut that withstands on the commentaries on classics of transmission housing lateral surface is to be with plane bearing at nut near on the pillow block periphery of gearbox one side, on one side the macropore of plane bearing is fixed with the clamp that protrudes nut shaft you head;
Described clamp is the two halves settings, and its two halves are stuck in the cannelure of plane bearing outboard nut pillow block periphery.
Advantage of the present utility model and good effect are: because an end of leading screw is screwed in the transmission spindle nose screw, the nut that is screwed on the leading screw withstands on the transmission housing lateral surface by plane bearing, and rotating nut is expressed to the travelling gear in the gearbox on the power transmission shaft under the motionless situation of leading screw reposefully, drive gearbox and move on to suitable installation site, not vibration, isostasy is not damaged spindle nose, can not hurt sb.'s feelings, safe and reliable, simple to operate, can improve 2 times of work efficiency.
Description of drawings
Fig. 1 is a cross-sectional schematic of the present utility model.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Among Fig. 1, right-hand member at leading screw 7, be provided with the screw thread spindle nose 8 that can be screwed in the machine running gear power transmission shaft 10 spindle nose screw, the bar portion of leading screw 7 is screwed with nut 2, be with plane bearing 3 on the periphery of the nearly gearbox 6 left side pillow blocks 2.1 in nut 2 right sides,, protrude the two halves clamp 5 of nut 2 right-hand member heads on one side the macropore of plane bearing 3 is fixed with ring washer 4, be stuck in the cannelure 5.1 on plane bearing 3 right side nuts 2 pillow blocks 2.1 peripheries, and be fixed on the ring washer 4 with bolt 9.
For convenience of rotating nut 2, be fixed with the handwheel 1 of nutting 2 usefulness at the left end of nut 2.
During use, earlier with the gear hole in the gearbox 6 on power transmission shaft 9 spindle noses, gearbox 6 also is enclosed within on the power transmission shaft 9 simultaneously, the screw thread spindle nose 8 of leading screw 7 front ends is passed gear hole in the gearbox 6, be screwed in the screw of power transmission shaft 9 terminations, holding the handwheel 1 of fixedlying connected with nut 2 rotates, nut 2 is close to gearbox 6 along leading screw 7, after treating that two halves clamp 5 leans against gearbox 6 left sides, be rotated further handwheel 1, utilize the motion of making a concerted effort of nut 2 and leading screw 7, the gears in the gearbox 6 are pressed on the power transmission shaft 9, gearbox 6 moves on to suitable installation site with gear.
Claims (3)
1, a kind of machine walking gearbox erector is characterized in that: at one end can be screwed on the leading screw in the machine walking transmission spindle nose screw, be with the one side and can withstand on the nut that rotates on the traction gear box shell lateral surface.
2, door machine walking gearbox erector as claimed in claim 1, it is characterized in that: the described nut that withstands on the commentaries on classics of transmission housing lateral surface, be to be with plane bearing near on the pillow block periphery of gearbox one side, on one side the macropore of plane bearing is fixed with the clamp that protrudes nut shaft you head at nut.
3, door machine walking gearbox erector as claimed in claim 2, it is characterized in that: described clamp is the two halves settings, its two halves are stuck in the cannelure of plane bearing outboard nut pillow block periphery.
