A kind of beam locking device of improved bridge type stone cutting machine
Technical field
The utility model relates to the beam locking device in bridge type stone cutting machine field, particularly a kind of improved bridge type stone cutting machine.
Background technology
At present, existing bridge type stone cutting machine is mainly by crossbeam, longeron and host apparatus form, beam erection is setting up separately on two longerons of position, the left and right sides, be provided with the longeron track on the longeron, the longeron track is " worker " font track, between crossbeam and longeron track, be provided with for driving crossbeam and do the longitudinal moving device that vertical equity moves along the longeron track, between longitudinal moving device and longeron track, be provided with beam locking device, beam locking device includes the mount pad that is fixedly connected on the longitudinal moving device, be arranged at the locking rack on the mount pad, be used for driving the oil cylinder of locking rack lifting, locking rack is by top board, connect and parallel two relative perpendicular side plate with the top board both sides, and be arranged at respectively on the corresponding perpendicular side plate and two dops that stretch in " worker " font track both sides form, this dop and longeron track contact side are the inclined plane, control dop and longeron track formation locking state or release by the locking rack lifting action, the horizontal horizontally disposed cross spacing bar that has between longeron track and mount pad on two perpendicular side plate of locking rack.The locking device structure of this kind structure is complicated, and because dop and longeron track be when being in locking state, the inclined-plane of dop can't with longeron track inwall close fit, so crossbeam is prone to and rocks or be offset when locking, and affecting machining accuracy, locking effect is undesirable.
The utility model content
Main purpose of the present utility model is the shortcoming that overcomes prior art, and the beam locking device of the better improved bridge type stone cutting machine of a kind of locking effect is provided.
The utility model adopts following technical scheme:
A kind of beam locking device of improved bridge type stone cutting machine, be arranged between the longitudinal moving device and longeron track of crossbeam, described longeron track is " worker " font track, include the mount pad that is fixedly connected on the longitudinal moving device, be arranged at the locking rack on the mount pad, be vertically installed on the mount pad and be connected in the driving oil cylinder that be used for to drive the locking rack lifting of locking rack, when locking rack rises to the higher position, locking rack and longeron track form locking state, when locking rack drops to lower position, locking rack discharges the longeron track, be formed with two dops that stretch in " worker " font track grooves on two sides on the described locking rack, this dop when locking rack is locked with the contact-making surface of " worker " font track plane for matching with the upper wall of " worker " font track grooves on two sides.
Described locking rack is one the upper rail bag of " worker " font track can be established grooved ring in the inner, and this grooved ring inside is formed with the liftable space, and these grooved ring both ends form dop, and upper wall is connected with the driving oil cylinder.
When locking rack rose to the higher position, dop and longeron track formed locking state, and when locking rack dropped to lower position, dop discharged the longeron track.
The cylinder body of described driving oil cylinder vertically is fixed on the described mount pad, and its piston rod is fixedly connected on the locking rack upper wall.
Be provided with the road wheel that matches with the longeron track on the described longitudinal moving device and be connected in the rotary oil cylinder that described road wheel is used for driving its rotation.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the beneficial effects of the utility model are: simple in structure, and dop when locking rack is locked with the contact-making surface of " worker " font track plane for matching with the upper wall of " worker " font track grooves on two sides, therefore when locking dop with " worker " but font track close fit, locking effect is better, therefore can avoid crossbeam to rock or be offset, and machining accuracy is higher.

The specific embodiment
Below the utility model will be further described by the specific embodiment.
With reference to Fig. 1, Fig. 2 and Fig. 3, the beam locking device of a kind of improved bridge type stone cutting machine of the present utility model, be arranged between the longitudinal moving device 2 and longeron track 3 of crossbeam 1, described longeron track 3 is " worker " font track, include the mount pad 4 that is fixedly connected on the longitudinal moving device 2, be arranged at the locking rack 5 on the mount pad 4, be vertically installed on the mount pad 4 and be connected in the driving oil cylinder 6 that be used for to drive locking rack 5 liftings of locking rack 5, when locking rack 5 rises to the higher position, locking rack 5 forms locking state with longeron track 3, when locking rack 5 drops to lower position, locking rack 5 discharges longeron track 3, be formed with two dops 7 that stretch in " worker " font track grooves on two sides on the described locking rack 5, this dop 7 is the plane of matching with the upper wall of " worker " font track grooves on two sides with the contact-making surface of " worker " font track when locking rack 5 locking.
With reference to Fig. 1, Fig. 2 and Fig. 3, described locking rack 5 is one the upper rail bag of " worker " font track can be established grooved ring in the inner, and this grooved ring inside is formed with the liftable space, and these grooved ring both ends form dop 7, and upper wall is connected with driving oil cylinder 6.When locking rack 5 rose to the higher position, dop 7 formed locking state with longeron track 3, and when locking rack 5 dropped to lower position, dop 7 discharged longeron track 3.The cylinder body of described driving oil cylinder 6 vertically is fixed on the described mount pad 4, and its piston rod is fixedly connected on locking rack 5 upper walls.Be provided with the road wheel 8 that matches with longeron track 3 on the described longitudinal moving device 2 and be connected in the rotary oil cylinder 9 that described road wheel 8 is used for driving its rotation.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
