Abstract
The utility model discloses a steel rolling mill supports roll chock letter easily movable formula dismounting device, including locomotive and handle, its characterized in that: the rear portion is equipped with the vertical fixation board in the locomotive frame, is equipped with the single arm -drag in vertical fixation board both sides, is equipped with the drag hook at the single arm -drag tip, the frame middle part of locomotive is equipped with linear electric motor, and linear electric motor seat end is fixed on the preceding face of vertical fixation board, and it is fixed that the cushion is passed through to linear electric motor's lower part, linear electric motor's the axis of telescopic shaft parallel with the single arm -drag of both sides. This dismounting device owing to having replaced the use hydro -cylinder through linear electric motor, so saved hydraulic system, makes equipment structure simple, since adopt electric drive, thus easy to operate control, convenient to use, under the effect of having adopted drag hook and telescopic shaft to remove in opposite directions, make the bearing frame lift off from the backing roll tip, so reduced by a power drive structure, it is more convenient that the messenger operates, since with whole equipment fixing on the locomotive, the institute is so that move.
Description
Technical field
This utility model is related to a kind of improvement of device for withdrawing bearing race of support, and specifically a kind of steel rolling mill supports
Roll bearing seat movable simple provision for disengagement.
Background technology
The milling train that steel rolling mill uses, in the operation of rolling, support roller can produce abrasion, scuffing and fatigue layer etc. and lack with bearing
Fall into, accordingly, it would be desirable to regularly disassemble the bearing block at support roller two ends, be modified.Due to Support roller assembly it is heavier, axle
It is only 0.5mm to hold fit clearance, and aligning requirements are higher during bearing dismantling, so special dismounting equipment must be adopted.Mesh
Front used special dismounting equipment, including hoist cylinder, voussoir, platform for placing, translation oil cylinder, hydraulic system composition, it is this special
It is with the deficiency existing for detaching equipment：One is complex structure, and cost of manufacture is high；Two is that bearing capacity is not enough, causes platform
Deformation；Three is that positioning precision is inaccurate.
By retrieval, in order to overcome the deficiencies in the prior art, Chinese patent 200520022640.9 to disclose one kind
" device for withdrawing bearing race of support roller of rolling mill ", by hoist cylinder the lifting and fixation of support roller are realized, by sliding platform to
Outer slip pulls bearing block, and sliding platform is realized by pulling oil cylinder.This " device for withdrawing bearing race of support roller of rolling mill ", by
In still employing hoist cylinder and pulling oil cylinder, so must be equipped with hydraulic system, cause structure still very complicated, be fabricated to
This is still higher, it is not easy to operational control；And equipment is not easily moveable.
The content of the invention
The purpose of this utility model is to provide one kind to dismantle supporting roller bearing seat, and simple structure, system
Make low cost, be easy to mobile, sturdy and durable, easy to operate steel rolling mill's supporting roller bearing seat movable simple provision for disengagement.
In order to reach object above, the technical scheme that this utility model is adopted is：Steel rolling mill's supporting roller bearing seat letter
Easily movable type provision for disengagement, including locomotive and handle, it is characterised in that：The vehicle frame postmedian of described locomotive is provided with vertically
Fixed plate, in the both sides of vertical fixing plate torque arm is provided with, and in the end of torque arm drag hook is provided with；The vehicle frame middle part of described locomotive
Linear electric motors are provided with, the seat end of linear electric motors is fixed on the front face of vertical fixing plate, the bottom of linear electric motors passes through cushion block
Fixed, cushion block is welded on the vehicle frame of locomotive；The axis of the telescopic shaft of described linear electric motors is parallel with the torque arm of both sides.
This utility model is also implemented by following measure：The back-end location of described torque arm is provided with length-adjustment holes, passes through
It is fixed in the horizontal through hole of the different length-adjustment holes of insertion bearing pin insertion and vertical fixing plate, realize that the length of both sides torque arm is same
Step section.
The rear plate face both sides of described vertical fixing plate are provided with support reinforcing plate, and by support reinforcing plate vertical fixing plate is made
Firmly.
Described linear electric motors are connected with 380V power supplys, and linear electric motors are prior art, can directly commercially, therefore
Seldom state.
Described locomotive includes vehicle frame, wheel, is prior art, therefore seldom states.
The beneficial effects of the utility model are：Steel rolling mill's supporting roller bearing seat movable simple provision for disengagement, with mesh
The front device for withdrawing bearing race of support roller of rolling mill for using is compared, and due to instead of by linear electric motors oil cylinder is used, so saving
Hydraulic system, makes the device structure simple；Due to adopting driven by power, so easily operational control, easy to use；Due to adopting
In the presence of drag hook is moved towards with telescopic shaft, bearing block is made from supporting roll end to unload, so reduce a power driving
Dynamic structure, makes more convenient to operate；Due to whole equipment is arranged on locomotive, institute is in order to movement.
Description of the drawings
Fig. 1 is structure schematic top plan view of the present utility model.
Fig. 2 is structure schematic side view of the present utility model.
Specific embodiment
This utility model is made with reference to Fig. 1, Fig. 2.Steel rolling mill's supporting roller bearing seat movable simple provision for disengagement, including
Locomotive 1 and handle 2, it is characterised in that：The vehicle frame postmedian of described locomotive 1 is provided with vertical fixing plate 3, is vertically fixing
The both sides of plate 3 are provided with torque arm 4, and in the end of torque arm 4 drag hook 5 is provided with, and when using, by the drag hook 5 of both sides torque arm 4 support are hooked
Roll bearing seat；The vehicle frame middle part of described locomotive 1 is provided with linear electric motors 6, and the seat end of linear electric motors 6 is fixed on vertical fixing plate
On 3 front face, the bottom of linear electric motors 6 is fixed by cushion block 7, and cushion block 7 is welded on the vehicle frame of locomotive 1；Described is straight
