Abstract
The utility model provides a bearing frame dismounting device, work efficiency was low when it had solved the dismantlement of current bearing frame, the security is poor and the narrower technical problem of range of application, and it is equipped with base and roller frame, and the roller frame is fixed on the base, being equipped with the lumber skid on the roller frame, being fixed with the roll through fixing device on the lumber skid, bearing detaching device uses the roller frame to be symmetry setting as the center, bearing frame dismounting device still is equipped with the dolly, and the dolly is equipped with lateral shifting device, longitudinal movement device and reciprocates the device, the utility model discloses but wide application in the dismantlement of bearing frame.
Description
Technical field
The utility model relates to a kind of provision for disengagement, particularly relates to a kind of bearing pedestal disassembling device.
Background technology
At present, comparatively traditional when the working roll that Metallurgical Enterprise grinding roller workshop uses, the dismounting of intermediate calender rolls bearing block, a sleeve-bearing at least needs two people's operations, and not only operating efficiency is lower, and roll does not have fixed clamping device yet, is easy to personal safety accident occurs.Some heavy steel rolling mill uses that special roll disassemblerassembler is bulky, cost is higher, not easily promotes the popularization use in medium and small steel rolling mill.
Summary of the invention
The utility model, for the narrower technical problem of inefficiency, poor stability and range of application during the dismounting of existing bearing block, provides that a kind of operating efficiency is high, security good and the bearing pedestal disassembling device of applied range.
For this reason, the utility model is provided with base and roll stand, and roll stand is fixed on base; Roll stand is provided with chock, and chock is fixed with roll by fixture, and bearing disassembling device is symmetrical set centered by roll stand; Bearing pedestal disassembling device is also provided with dolly, and dolly is provided with horizontal mobile device, longitudinal moving device and moves up and down device.
Preferably, longitudinal moving device is provided with longitudinal rail, lower movable block, longitudinal motor and gear rack arrangement, and lower movable block is located on longitudinal rail, and longitudinal motor is located on lower movable block, and longitudinal motor is connected with gear rack arrangement.
Preferably, move up and down device and be provided with worm gear device and lifting motor, dolly is connected with worm gear device, and worm gear device is connected with lifting motor.
Preferably, horizontal mobile device is provided with hydraulic jack, cross slide way and upper movable block, and hydraulic jack and cross slide way are located on lower movable block, and upper movable block is located on cross slide way.
The utility model beneficial effect is that dolly lifting adopts worm and gear lift, transmits power by frequency control motor and cycloidal planetary gear speed reducer, can ensure at a slow speed crawl lifting error 0.02mm during adjustment; Longitudinally walking passes through rack pinion by variable-frequency motor and reductor, thus realizes the fast low-speed running of cross traveling trolley and accurately brake location; Horizontal dolly is retreated and is realized fast slow-action by single-acting three grades of oil cylinders and corresponding speed regulating control valve and to adjust position, and off-load when can realize overload, thus ensure the safety of operation and equipment; Roll lifts after to teardown stand, and fixture clamps roll by clamp, to ensure the safety of dismounting; Plant bottom case adopts set bolt to add cement Grouting Design, and what ensure between each parts is relatively stable and basic firm; Centered by roll stand, design two symmetrical cover electrical apparatus control systems, and respectively join a set of hydraulic system; Structure is simple, and convenient operating maintenance, cost is lower, and range of application is comparatively extensive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Symbol description in figure:
1. roll; 2. base; 3. bearing block; 5. chock; 6. hydraulic jack; 8. worm gear device; 11. cross slide waies; 12. longitudinal rails; 16. gear rack arrangement; 18. longitudinal motors; 20. roll stand; 22. fixtures; 24. dollies; 26. lifting motors.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described further.
As shown in Figure 1, the utility model is provided with base 2 and roll stand 20, and roll stand 20 is bolted on base 2, meanwhile, base 2 is also provided with cement grout, roll stand 20 and base 2 is fixed together firmly, maintains higher stability.
Roll stand 20 is provided with chock 5, and roll 1 to be just positioned on chock 5 and to be fixed by fixture 22, and roll 1 cannot be horizontally slipped.The utility model is symmetrical set centered by roll stand 20, is described below to the structure of roll stand 20 side.
Base 2 is provided with two symmetrical longitudinal rails 12, longitudinal rail 12 is provided with lower movable block, lower movable block is provided with longitudinal motor 18, longitudinal motor 18 is connected with gear rack arrangement 16, when longitudinal motor 18 works, it drives lower movable block movable on longitudinal rail 12 by gear rack arrangement 16.
Lower movable block is also provided with cross slide way 11, cross slide way 11 is provided with movable block, upper movable block is provided with dolly 24, dolly 24 is connected with worm gear device 8, worm gear device 8 is connected with lifting motor 26, when lifting motor 26 works, it can drive dolly 24 to move up and down by worm gear device 8.
Lower movable block is also provided with three grades of hydraulic jacks 6, the dolly 24 above upper movable block can be made to move left and right on cross slide way 11 by hydraulic control oil cylinder.
By the below of above-mentioned all around, upper and lower direction travelling car 24 to bearing block 3, treat to make after bearing block 3 is dismantled dolly 24 slowly leave roll 1, after leaving roll 1 completely, can movement fast, save the working time, increase work efficiency.
Only as described above; be only specific embodiment of the utility model; when can not limit the scope of the utility model enforcement with this; therefore the displacement of its equivalent assemblies; or the equivalent variations to do according to the utility model scope of patent protection and amendment, all still should belong to the category that the utility model claims are contained.
