Abstract
The invention discloses a quick cutter sheath dismantlement tool for repairing of a milling and planing rotor of a pavement milling planer, and relates to an engineering machine. The dismantlement tool comprises a screw, a carrying lever and a clamp plate, wherein the carrying lever is mounted at the upper end of the screw, an annular clamp groove is manufactured at the lower end of the screw, the clamp plate is an annular plate, the diameter of a hole of the annular plate is larger than that of a groove bottom circle of the annular clamp groove, an opening groove is manufactured on the annular plate, and the width of the opening groove is equal to the diameter of the hole of the clamp plate. During usage, a check bolt and a check washer are dismantled at first, then the screw is screwed into a threaded hole on a cutter sheath, when the end of the screw is exposed out of the end of a base, the opening groove on the clamp plate is inserted into the annular clamp groove on the screw, then the carrying lever is mounted on the screw, the screw rotates anticlockwise, the cutter sheath is driven via the threaded hole to move upwards, and a conical surface on the cutter sheath is separated from a conical hole of the base. The quick cutter sheath dismantlement tool realizes dismantlement conveniently and quickly, time and labor are saved, and the cutter sheath and the base cannot be damaged.
Description
Technical field
The present invention relates to a kind of machinery of paving the way, be specifically related to the maintenance of pavement milling machine milling rotor with the quick extracting tool of broach shell.
Background technology
Pavement milling machine is the capital equipment of road maintenance, and milling rotor high-speed rotation is carried out the milling fragmentation with the bituminous paving, cement pavement and the various roadbed that damage, and the material that cuts focuses on the middle part of milling rotor along helicoid, gets into hopper then.Because face to be repaired the roads is uneven, geology is hard; Cutting system rotates at a high speed; Cutter head, broach shell and pedestal often damage, during that the applicant has invented is a kind of " use on the pavement milling machine can rapid changing knife milling rotor ", and cutter head, pedestal convenient disassembly; Obtain good effect, applied for national patent.Because broach shell is installed in pedestal through tapered hole, is connected firmly; Pedestal, broach shell layout are intensive, and the space that is used for the broach shell dismounting is narrow and small.Broach shell dismounting at present mostly is to hit or support outward with lever with hammer, and broach shell is moved outward.Because the space is narrow and small between the adjacent susceptors, dismounting is difficulty very, even can't dismantle, and labour intensity is big, inefficiency.In addition, the mating surface between broach shell and the pedestal is a thorough seal, though the reservation grease is arranged, can't replenish immediately and clear up, and bonding, corrosion etc. can occur for a long time, causes more difficulty of dismounting.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention provides a kind of pavement milling machine milling rotor maintenance with the quick extracting tool of broach shell, is made up of screw rod, moving bar and clamp; Utilize the moving bar contra rotating screw; Screw rod drives the end face that moves on to pedestal on the clamp, and clamp is static, continues firmly contra rotating screw; Screwed hole on the pedestal drives on the broach shell and moves, and is separated with the pedestal taper hole.
The present invention sends out realization through following technology: a kind of pavement milling machine milling rotor maintenance is with the quick extracting tool of broach shell, and it is characterized in that: it comprises: screw rod, moving bar and clamp.Described moving bar is installed in the upper end of screw rod, and described screw rod lower end makes annular slot.Described clamp is the annular plate, and the aperture of annular plate falls greater than the bottom land circular diameter of described annular slot, makes open slot on the annular plate, and the groove width of described open slot equates with the aperture of clamp.
Being connected between described moving bar and the screw rod is fixedly connected or flexibly connects.Moving bar and screw rod are for flexibly connecting, and when extracting tool did not use, moving bar and screw rod broke away from.
Good effect of the present invention is:
1, the broach shell convenient disassembly is quick, and laborsaving saving time can not damaged broach shell and pedestal.
2, simple and reasonable for structure, cost of manufacture is low, is convenient to promote the use of.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further explain.
Fig. 1 is pavement milling machine milling rotor broach shell, cutter head installation site sketch map.
Fig. 2 is a broach shell unloading process sketch map.
Fig. 3 is a structural representation of the present invention.
Fig. 4 is the A-A profile of Fig. 3.
Among the figure: 1, cylindrical shell, 2, pedestal, 3, check bolt, 4, lock washer, 5, broach shell, 5-1, screwed hole, 6, cutter head, 7, moving bar, 8, screw rod, 8-1, draw-in groove, 9, clamp, 9-1, open slot.
The specific embodiment
The installation site of pavement milling machine milling rotor shown in Figure 1, the milling rotor comprises: cylindrical shell 1, pedestal 2, broach shell 5 and cutter head 6.Described cylindrical shell 1 gains impetus from the power source of milling machine, drives cylindrical shell 1 rotation at a high speed.Described cutter head 6 is installed on the broach shell 5, and described broach shell 5 is installed on the pedestal 2, and the bottom surface of described pedestal 2 is welded on the face of cylinder of cylindrical shell 1.In order to guarantee that broach shell 5 can not come off in the course of the work, broach shell 5 endoporus are made screwed hole 5-1, utilize check bolt 3 and lock washer 4 that broach shell 5 is strained.
Like Fig. 3, shown in Figure 4: a kind of pavement milling machine milling rotor maintenance comprises with the quick extracting tool of broach shell: screw rod 8, moving bar 7 and clamp 9.Described moving bar 7 is installed in the upper end of screw rod 8, and described screw rod 8 lower ends make annular slot 8-1; Described clamp 9 is the annular plate, and the aperture of annular plate falls greater than the bottom land circular diameter of described annular slot 8-1, makes open slot 9-1 on the annular plate, and the groove width of described open slot 9-1 equates with the aperture of clamp 9.
Being connected between described moving bar 7 and the screw rod 8 is fixedly connected, and also can be to flexibly connect.During flexible connection, extracting tool does not use, and can moving bar 7 and screw rod 8 be broken away from, and moving bar 7, screw rod 8 and clamp 9 are put in the tool box, is convenient to deposit, takes care of and carry.
Like Fig. 1, shown in Figure 2: broach shell 5 unloading process are: the first step: check bolt 3 and lock washer 4 are disassembled.Second step: in the screwed hole 5-1 on the screw rod 8 screw-in broach shells 5, the end that makes screw rod 8 ends expose pedestal 2.The 3rd step: the open slot 9-1 on the clamp 9 is inserted among the annular slot 8-1 on the screw rod 8.The 4th step: moving bar 7 is installed on the screw rod 8.The 5th step: contra rotating screw 8, screw rod 8 drives on the clamp 9 and moves, and the end face that moves on to pedestal 2 on the clamp 9 is static, continues firmly contra rotating screw 8, and screw rod 8 drives on the broach shell 5 through screwed hole 5-1 and moves, and the conical surface on the broach shell 5 and pedestal 2 taper holes are separated.The 6th step: take off extracting tool and broach shell 5.Broach shell 5 convenient disassemblies are quick, and laborsaving saving time can not damaged broach shell 5 and pedestal 2.
