Description

The invention relates to construction equipment, namely, devices for cutting and crushing bitumen. A known installation for cutting bits, comprising a support frame with a cutting mechanism arranged in it in the form of a two-arm clamshell gripper, each jaw of which is provided with parallel ribs with knives or crushing stops, between which pushers are suspended on the axis of the jaws. The movement of the jaws is carried out by two hydraulic cylinders, hinged on a stitch to each of the jaws and located on the external face side. The construction of the bitumen arm mechanism makes it impossible to use this installation as a clamshell grab to separate one bitumen bay from the total mass. In addition, when cutting blades with knives, bitumen, due to its physical properties, does not compact, does not contract, but is displaced in different directions, and additional forces in the horizontal plane arising from the displaced bitumen act on knives, which leads to an increase in cutting and, accordingly, the gesture of the bone and the weight of the installation. The closest to the invention is a device for cutting bitumen containing a traverse, a two-jaw clamshell grab, the jaws of which are hingedly fixed Hbix on the corresponding axes of the half-bridges with slots in the side walls for knives with fingers, placed in parallel in each semi-subzone and kinematically connected to semi-podsons by means of a mechanism of laziness, having swiveling shackles which engage with the fingers of knives, located between the axes of fastening the peschoupoddons and the lead screw with which and each pair of knives by means of carriages for moving them along half-pallets horizontally, and a device for locking half-pallets C 2. However, in the known device, manual control of the clutch mechanism requires constant presence of the operator, which is especially inconvenient at the moment of capturing the bitumen bay from the total mass and at the time zasyshki crushed bitumen in the digester. The control of the clutch mechanism is carried out only on one side of the installation, which causes certain difficulties during operation when the approach to the clutch control handle for some reason is inconvenient. This adversely affects the performance of the device and complicates its operation. The purpose of the invention is to increase productivity and simplify operation. The goal is achieved by the fact that in a device for cutting bitumen containing a traverse, a two-maxillary claw is gripped, the jaws of which are made pivotally fixed on the respective axes of semi-pallets with slots in the side walls for knives with fingers placed in parallel in each semi-pallet and kinematically connected to the podpodortson through the mechanism of the clutch, which has meshes with the fingers of the knives of the shackle of the clevis, located between the axles of the mounting of the pallets pod screw, with which Each pair of knives is provided by means of carriages for moving them along the half-pallets horizontally, and a device for locking half-pallets, the knives are provided with forked movement on the fingers of the half-podsons forks with pushers interacting with the tailings mounted on the brackets, and the device for locking the half-pallets is made as attached to the respective side walls of the semi-pallets of a pre-loaded latch and a locking element, wherein the latch by means of two The levers are kinematically connected with: one of the knives. Figure 1 shows the device, a general view; Fig. 2 shows a section A-A in Fig. 1 (knives are coupled with semi-pod-dons, and the latter are not locked with each other); on fig.Z - section bb in figure 2 (bracket podpodtsona coupled with the finger of the knife); FIG. 4 is a view B of FIG. 3 (the shank of the staple and the counterweight); on fig.Z device at the time of capture of the bitumen bay (knives interlocked with semi-subdents); Fig. 6 is a section of GG in Fig. 5 (the mutual arrangement of the slats with grooves and U-shaped brackets with the fingers of the knives at the moment of engagement of the knives and half-podtsonov; fig.7- the knives are disengaged with the half-podsons, and the latter between them not locked; FIG. 8 is a cross section of D-D in FIG. 7 (the relative position of the slats with grooves and the fingers of the knives with brackets at the moment of the disengagement of the knives and half-sub-pods); Fig. 9 is a section E-E of Fig. 8 (a clutch mechanism at the time of unlocking the knives and semi-pallets); in fig. 10 - device before cutting bitumen (knives are divorced, pallets are locked with each other). The device for cutting bitumen consists of a crosspiece 1, which with the help of an earring is hung on any crane mechanism (not shown). In traverse 1, two axes 2 and a spindle 3 with a flywheel 4, which are between them, are fixed parallel to each other. Two half-pallets 5 and two pairs of knives 6 are hinged on the axis x 2, which with the help of special carriages 7 move in the horizontal plane (along the bitumen bay) under the action of the traveling screw 3. To move the knives 6, when cutting bitumen, in each pair, hydraulic structures 8 are mounted, which work synchronously. In order to cut the bitumen bay in half, there are slots 9 available. The hydraulic cylinders are controlled from the remote control 10, which sends signals to the starting equipment of the pump station 11 located on a special platform suspended from the traverse. The connection and disengagement of the knives with semi-podsons provides the mechanism of adhesion, and the connection and separation of the semi-sub-pods among themselves is a device for constipation; pallets The mechanism of the clutch of knives with the floor sub-sets consists of rotary U-shaped brackets 12 mounted on horizontal axes in the side walls of the semi-pallets 12. Internal cheeks 13 U-shaped brackets 12 facing inwards of the semi-pallet, i.e. to the knives 6, they have verticular grooves 14 and curved shanks 15 directed towards opening the semi-pallets. The outer cheeks 16 of the U-shaped brackets 12 have counterweights 17, due to which the brackets 12 are held in a vertical plane and the counterbalances 17 are pressed against the walls of the half-subdiots 5. Before the swinging U-shaped brackets 12, from the side of the plane of the connector, approximately at the level of the lower edges of the cheeks U- figurative staples 12, through fingers 18 are mounted with forked rods 19, which have grooves 20, due to which they can move along fingers 18 and rotate relative to them. The slats 19 at the ends opposite to the plane of the connector of the half-podsons and knives have weights 21, due to which they tend to occupy a vertical position. Above the bars 19, on the end walls of semi-podsotsonov installed. guide plates 22, and under the planes — supporting crackers 23. On the outer side of each knife, facing the end wall of the half-pallete, fingers 24 and pushers 25, shaped as a shelf, are installed. The installation has two coupling mechanisms located on both end walls of the pallet. The mechanism for locking the semi-pallets includes the following elements: a rotary latch 26 with a spring 27 and an angular lever 28. sitting on the same semi-pallet. A finger 29 is mounted on the knife, sitting coaxially with this half-pallet. On the half-pallet sitting on the other axis, a locking element (pin) 30 is installed. The installation has two locking mechanisms located on the outer sides of both ends of the pallet walls. The device works as follows. To separate the bitumen. From the total mass, you need to use the control buttons on the remote control 10 to turn on the electric motor of the pump station 11, while the working fluid is injected into the cavity of the hydraulic cylinders 8 in order to open and close the semi-subdoms 5 and the knives 6, interconnected by means of a clutch mechanism. The operation of the mechanism for coupling the knives to the pallets and the fixtures i1 for constipation of the pallets is carried out in the following order. In the initial position (Fig. 2), when the semi-pallets 5 and the knives 6 are closed, the slats 19 by the pushers 25 are raised in the upper, positioned, inclination by the guide plates 22 towards the plane of the connector and touch each other. The fingers of the 24 knives are located in the vertical slots .14 of the clips 12, i.e. the knives and semi-pallets are in the engaged position. The latches 26 are raised by the angular levers 28, which are pressed by the finger 29 of the knives 6. To capture the bitumen bay, the semi-pallets 5 to the knives 6 are in the open position (Fig. 5). The slats 19 are fed to the supporting crackers 23 and occupy a position perpendicular to the surface of the connector. The latches 26 remain in the raised position. When the bitumen bay is seized, the semi-pallets 5 with the knives 6 are closed (Fig. 7). In this case, the strips 19 with their ends hit each other and move, due to the presence of the grooves 20, to the extreme positions from the plane of the connector. At the same time, their opposite ends go between the counterweights 17 with beveled edges. U-shaped brackets 12 and end stands of semi-pallets 5, deviation of U-shaped brackets 12 from the vertical field. The inner cheeks 13 of the U-shaped brackets with the grooves 14 come out of engagement with the fingers of the 24 knives 6. Thus, the knitting of the knives with the half-subdoms occurs. The latches 26 remain in a raised position. To cut the bitumen bay, you need to open the knives 6, while the half-subdoms 5 remain closed and locked with the latches of the 26 locks (figure 10) At the initial moment of opening the knives, the fingers 29 mounted on them move away from the corner levers 28 and necks 26 under the action of springs 27 capture pin 30 installed on opposing pallets, locking in half semi-subdoms between themselves 40 Planks 19 with grooves 20 on semi-pallets at the expense of weights 21 occupy the lower position. Using the lead screw 3, the knives in the open position are transferred to the second grooves 9 in the semi-pallets (Fig. 1), from which the cutting of the bitumen bay begins. After cutting the bitumen coil, the knives 6 in the open position return to their original position, i.e. to the first pa3 am 9 podpodtsonov. Before opening the semi-pallets and pouring out the chopped bitumen, the knives close and engage with the semi-pallets, and the latter are disconnected (Fig. 1). When the knives are closed, the fingers 24 mounted on them press down on the curved shanks 15 of the staples 12 and deflect them from the vertical position. After the knives are fully closed, the vertical grooves 14 on the inner cheeks 13 of the brackets 12. will be shown - against the fingers of the 24 knives and the brackets 12 will again take up a vertical position. There is a clutch of knives with pallets. At the same time, the pushers 25 mounted on the knives raise the strips 19 with the slots 20 into the upper position when they are closed. At the end of the knives closing stroke, the fingers 29 press down on the angular levers of the 28 semi-pallets, deflecting them forward, and in turn pushing the shanks the latches 26, lifting them upwards and disengaging them from the shafts 30. Thus, the semi-pallets are not locked and when opening the blades they are pushed apart, the bitumen is broken out and dried out. The proposed mechanism for coupling the knives to the pallets does not need to be set to the starting position before starting work, it automatically takes up this position and no operator intervention is required. The semi-sub tanks are automatically locked with each other at the moment of cutting the bitumen bay and automatically unlocked when the bitumen being cut is poured into the boiler.
