Abstract

The utility model relates to a mobile roller replacing device for a twenty-high roll mill. An oil feeding unit is disposed on the rear side of a vehicle body. The oil feeding unit is communicated with an oil motor driving the vehicle body to move back and forth, an oil motor driving a jaw to move a screw rod in the transverse direction, an oil motor driving the jaw to move the screw rod in the vertical direction and an oil cylinder driving the jaw to open or close through pipelines. The oil feeding unit is disposed on the rear side of the vehicle body and communicated with the oil motor driving the vehicle body to move back and forth, the oil motor driving the jaw to move the screw rod in the transverse direction, the oil motor driving the jaw to move the screw rod in the vertical direction and the oil cylinder driving the jaw to open or close through hard tubes, and therefore the hard tubes are not prone to leakage; a great deal of working space is increased after a drag chain is eliminated; and the oil feeding unit plays a role of balance weight so that the vehicle body is more stable and safe in the process of replacing rollers.

Description

The portable changing rig of mill
Technical field
The utility model relates to mill roll change technical field, especially the portable changing rig of mill.
Background technology
Portable changing rig is the equipment of the working roll, an intermediate calender rolls and two intermediate calender rolls that are used for changing mill; It is installed on the track before the milling train, and its structure is as shown in Figure 1, and the wheel 9 that install car body 10 bottom surfaces is crimped on the track 8; At car body rear side mounting bracket 3; The leading flank of this support is installed the traversing leading screw 4 of transversely movable jaw, and the traversing leading screw of this jaw drives framework 6 level runs, and jaw vertical shift leading screw 5 is installed in this framework; This jaw vertical shift leading screw drives jaw 7 and vertically moves, and jaw can separate up and down to realize the clamping of roll body.
Above-mentioned car body moves forward and backward, the traversing leading screw of jaw and jaw vertical shift leading screw use three oil motors respectively; Deciliter use oil cylinder up and down of jaw; Three oil motors and oil cylinder are all through the surface-based hydraulic valve bank of soft pipe connection, and this hydraulic valve bank is communicated with fuel tank through oil pump.What these flexible pipes were intensive is arranged in the interorbital drag chain, can drive drag chain when car body moves and move, and is prone to cause damage, and long drag chain also can influence operating personnel's working space, and the flexible pipe in the drag chain arrange crowded, in case reveal easy-maintaining not.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of portable changing rig of mill convenient, safety and stability that moves is provided.
The technical scheme that the utility model is taked is:
The portable changing rig of a kind of mill; Comprise car body, the traversing leading screw of jaw, jaw vertical shift leading screw and jaw; The traversing leading screw level of jaw is installed in car body and attendes on institute's dress support; Jaw vertical shift leading screw vertically is installed in the framework that is driven by the traversing leading screw of jaw; Jaw vertical shift leading screw drives jaw, it is characterized in that: at the car body rear side one fueller is installed, this fueller is communicated with the oil cylinder of oil motor, the oil motor that drives the traversing leading screw of jaw that drives car body and move forward and backward, the oil motor that drives jaw vertical shift leading screw and the folding of driving jaw respectively through pipeline.
And said fueller comprises fuel tank, hydraulic valve bank and oil pump, and fuel tank is installed in the car body rear side, and hydraulic valve bank and oil pump are installed on the fuel tank, and fuel tank is communicated with three said oil motors and oil cylinder respectively through oil pump and hydraulic valve bank.
And said fuel tank is installed on the carriage of car body institute dress support trailing flank.
The advantage and the good effect of the utility model are:
In the utility model; Fueller is installed in the rear side of car body; Its oil motor, oil motor that drives the traversing leading screw of jaw that moves forward and backward through hard tube connection driving car body, the oil cylinder that drives three oil motors of jaw vertical shift leading screw and drive the jaw folding, hard tube connects not easy to leak, has increased a large amount of working spaces behind the omission drag chain; And fueller played the effect of counterweight, make car body when changing roll more steadily, safety.
Description of drawings
Fig. 1 is the front view of the utility model.
The specific embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit the protection domain of the utility model with following embodiment.
The portable changing rig of a kind of mill; As shown in Figure 1; Comprise the traversing leading screw of car body 10, jaw 4, jaw vertical shift leading screw 5 and jaw 7; Car body moves on track 8 through wheel 9, and a support 3 is installed on it, and level is installed the traversing leading screw of jaw on this support; Jaw vertical shift leading screw vertically is installed in the framework 6 that is driven by the traversing leading screw of jaw; Jaw vertical shift leading screw drives jaw, and the innovation of the utility model is: at the car body rear side one fueller is installed, this fueller is communicated with the oil cylinder of oil motor, the oil motor that drives the traversing leading screw of jaw that drives car body and move forward and backward, the oil motor that drives jaw vertical shift leading screw and the folding of driving jaw respectively through pipeline.
In the present embodiment, fueller comprises fuel tank 12, hydraulic valve bank 1 and oil pump 2, and fuel tank is installed in the car body rear side, and hydraulic valve bank and oil pump are installed on the fuel tank, and fuel tank is communicated with said oil motor and oil cylinder respectively through oil pump and hydraulic valve bank.Because car body is less, so fuel tank is installed on the carriage 11 of car body institute dress support trailing flank.
In the utility model; Fueller is installed in the rear side of car body; It passes through hard tube and is communicated with the oil motor that drives the traversing leading screw of jaw, the oil cylinder that drives the oil motor of jaw vertical shift leading screw and drive the jaw folding, and hard tube connects not easy to leak, has increased a large amount of working spaces behind the omission drag chain; And fueller played the effect of counterweight, make car body when changing roll more steadily, safety.
