Abstract
The utility model relates to a rod lifting device which is characterized in that a lifting bracket is arranged on the rack, and the lifting bracket is connected with the rod through a connecting element. When in use, the lifting bracket is installed above the rod according to the utility model, the lifting bracket is connected with a rod bearing seat of the rod through a screw, and a nut matched with the lifting bracket is arranged above the screw. When needing to change a blanket, the nut is rotated, the rod is lift, and the blanket is easily changed after a gap is reserved. The whole mechanism is simple and convenient in operation, higher in efficiency and is capable of simultaneously lifting a plurality of rods without being limited by a travelling crane.
Description
Technical field
The utility model relates to the technical field of paper machine, specifically a kind of roller lifting device that is used for paper machine.
Background technology
In the prior art, if just needs replacing in time of excessive wear appears in paper machine woollen blanket in running, because woollen blanket is enclosed within the middle of the roller; To promote the rear replaceable for one ton roller to need driving to weigh; Whole process wastes time and energy, because driving setting receives the restriction in place and space, so in concrete the use; Can't promote a plurality of rollers simultaneously, influence the efficient of the replacing of paper machine.
Such as application number is " CN200910227784.0 ", and the applying date is " 2009.12.29 ", the artificial " Li Dongsheng of application; Wang Le; Li Dongxin ", name is called the patent of invention of " method of substituting mesh for felt in papermaking system of paper machine ", and comprised following description: described paper machine is in running; manufactured paper with pulp paper pulp out by net cage, and the l Water Paper page or leaf gets into the screen cloth operation and draws on the net roller, reruns to carrying roller to push; the l Water Paper page or leaf after the extruding is adhered on the drying cylinder; accomplish the process of manufacturing paper with pulp, and screen cloth continues operation, gets back to net cage through idler roller, wite roll, accent net roller, nip rolls and forms circulation.This shows that still need drive a vehicle in use will weigh one ton roller of the screen cloth after the improvement is just replaceable after promoting, inconvenience very.
Summary of the invention
The purpose of the utility model is to provide a kind of improved roller lifting device, need drive a vehicle when it can overcome in the prior art felt changing more to weigh that to promote the rear replaceable for one ton roller.Changing whole process wastes time and energy, and can't promote a plurality of rods simultaneously, influences the some shortcomings of production efficiency.
To achieve these goals, the technical scheme of the utility model is: a kind of roller lifting device, it mainly comprises frame and roller, it is characterized in that: frame is provided with a lifting support, links to each other through connector between described hoisting bracket and the roller.
During use, the utility model is installed a lifting support above roller, with screw rod hoisting bracket is linked to each other with the rod bearing block of rod, and the top of screw rod is provided with a nut engaged with it.When needs more during felt changing, rotation nut, roller just is raised, reserve the space after, woollen blanket just is easy to change.Entire mechanism is easy and simple to handle, and efficient is higher, can promote a plurality of rollers simultaneously, the restriction of not driven a vehicle.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
In the accompanying drawing, each mark is represented as follows: 1, frame, 2 hoisting brackets, 3 nuts, 4 screw rods, 5 rollers, 6 woollen blankets, 7 are extracted seat out.
The utility model mainly comprises frame 1 and roller 5, and its difference with the prior art is: frame is provided with a lifting support 2, links to each other through connector between described hoisting bracket and the rod.Connector is formed by connecting nut 3 and screw rod 4, and the roller center place is provided with the roller axle bearing, and described screw rod links to each other with the roller axle bearing.
In force, a lifting support is installed in roller top, and hoisting bracket is fixedly connected with frame, with screw rod hoisting bracket is linked to each other with the rod bearing block of roller, and the top of screw rod is provided with a nut engaged with it.When needs more during felt changing 6, rotation nut, roller just is raised, reserve the space after, extract seat 7 out, woollen blanket just is easy to change.The utility model has replaced original driving with simple bolt and nut mechanism, makes that the entire mechanism operation is very easy, has promoted the efficient of work, also can promote a plurality of rollers simultaneously, and the restriction of not driven a vehicle has and promotes and value.
