Description

A kind of pusher

Technical field

The utility model relates to steel processing equipment fields, and in particular to a kind of pusher.

Background technique

Pusher end pushes away cold steel billet (original blank) into laser heating stove heating, is that fortune in furnace is completed by charging steel pusher Expect heating tasks.Pusher is heating furnace key into steel equipment, is responsible for shifting original blank onto heating from roller-way by root It is heated in furnace, through frequently with hydraulic friction pusher in usual similar projects.By pushing away beam, hydraulic cylinder, guide rod, bearing block and bottom Disk forms hydraulic friction pusher, to push the process flow into furnace heating steel billet.Such pusher is in engineering practice process In expose as following drawbacks, since pusher is whole heavy, frictional force existing for equipment itself is excessive, therefore works in pusher When be easy to cause a large amount of mechanical energy to be lost, be easy to cause the waste of the energy.

In consideration of it, the improvement that the inventor of this case carries out in traditional pusher equipment, so that pusher is in work When consume less idle work.

Utility model content

In order to solve the above problem, the utility model is achieved through the following technical solutions:

A kind of pusher, including beam, chassis, bracket, hydraulic cylinder and push rod are pushed away, the hydraulic cylinder and bracket fixation are set Above the chassis, beam is pushed away described in hydraulic cylinder connection and is connected and pushes away beam described in pushing；The beam that pushes away is consolidated with the push rod Fixed connection, the bracket are equipped with perforation, and the push rod is set on the bracket and passes through the perforation, the push rod with it is described Hydraulic cylinder pushes away beam side described in being co-located at；It is characterized in that lower section is equipped with the item extended along push rod extending direction in the perforation Slot, the bar groove are provided with shaft, are articulated with idler wheel on the shaft.

Further, cavity is equipped in push rod.

Further, the sliding slot extended along the push rod is equipped with below push rod, push rod section lower end is in " W " shape, institute Sliding slot is stated to match with the idler wheel.

The utility model has the advantages that using the use of the new type, under the action of idler wheel, so that needing the weight overcome is big to push away originally Force of sliding friction in bar and perforation, becomes the force of rolling friction between push rod and idler wheel, to reduce a large amount of idle work Loss, it is more energy saving.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples, it should be understood that this is practical new The structure of type is not limited in following embodiment:

As shown in Figure 1-3, a kind of pusher, including beam 1, chassis 2, bracket 3, hydraulic cylinder 4 and push rod 5 are pushed away, it is described hydraulic Cylinder 4 and the bracket 3 are fixed at 2 top of chassis, and the hydraulic cylinder 4 connects the beam 1 that pushes away and is connected and pushes described push away Beam 1；The beam 1 that pushes away is fixedly connected with the push rod 5, and the bracket 3 is equipped with perforation 31, and the push rod 5 is set to the bracket 3 Go up and pass through the perforation 31, the push rod 5 and the hydraulic cylinder 4, which are co-located at, described pushes away 1 side of beam；It is characterized in that described Lower section is equipped with the bar groove 32 extended along 5 extending direction of push rod in perforation 31, and the bar groove 32 is provided with shaft 33, the shaft 33 On be articulated with idler wheel 34.

Hydraulic cylinder 4 pushes away the sliding of beam 1, while push rod 5 is with pushing away the activity of beam 1, and it is mobile that push rod 5 can guarantee to push away beam 1 Stability, in this case, by using the design of idler wheel 34, push rod 5 is ridden upon on idler wheel 34, in the process that push rod 5 is slided In need to only overcome force of rolling friction between push rod 5 and idler wheel 34, rather than the push rod 5 for needing to overcome in conventional, prior art with wear Force of sliding friction between hole 31 reduces the waste of mechanical energy.

Further, cavity 51 is equipped in push rod 5.Cavity 51 is set in push rod 5 can mitigate 5 weight of push rod, to reduce Force of rolling friction between push rod 5 and idler wheel 34 further decreases the loss of pusher entirety mechanical energy.

Further, the sliding slot 52 extended along the push rod 5 is equipped with below push rod 5, the 5 section lower end of push rod is in " W " Shape, the sliding slot 52 match with the idler wheel 34.Using sliding slot 52 is arranged below program push rod 5, so that original hollow pipe 5 section of push rod below be in " W " shape, by after curved, rigidity and stability increase severely, therefore can bear for the steel pipe of same intensity The load bearing stength of push rod 5 can be improved in bigger moment of flexure and torque, enhances the stability of push rod 5 itself；Meanwhile the cunning of push rod 5 Slot 52 is adapted with 34 position of idler wheel, it is ensured that size is adapted between push rod 5 and perforation 31, and there is no excessive extra Space.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Ability The technology people in domain is described in the above embodiment and specification it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model can also There are various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The utility model is wanted Protection scope is asked to be defined by the appending claims and its equivalent thereof.
