Abstract
The utility model discloses an installation structure of a shield machine scraper, comprising a tool bit body, a scraper pedestal and a shield machine spoke motherboard. The scraper pedestal is fixed on the shield machine spoke motherboard; the tool bit body is fixed on the scraper pedestal; and the upper end of the tool bit body is provided with a hard alloy block. The installation structure is characterized in that the shield machine spoke motherboard is provided with a fixing block; the rear end of the tool bit body is provided with a lateral bump which is clamped in a groove above the scraper pedestal; two parallel bolts are connected with the fixing block by using threads after sequentially passing through the tool bit body and the scraper pedestal; and the fixing block is provided with a technical hole. According to the installation structure of the shield machine scraper, disclosed by the utility model, the lateral bump on the tool bit body is clamped in a slot of the scraper pedestal, the tool bit body and the scraper pedestal are fixed on the fixing block of the shield machine spoke motherboard by using two bolts, and the fixing block is provided with the technical hole for mounting and dismounting the fixing block, so that the installation structure is simple and practicable and is convenient to mount and dismount, and the tool replacing efficiency and security are improved.
Description
Technical field
The utility model relates to the mounting structure of the mounting structure of shield machine cutter, particularly a kind of shield machine scraper.
Background technology
Shield machine is mainly used in the constructing tunnel, and the operating mode of shield-tunneling construction is generally comparatively abominable, and the wearing and tearing of cutter are inevitable; Often need to change cutter in the work progress; But because the restriction of shield machine working environment and operating principle causes changing cutter in the cutter head of shield machine front and has bigger risk, if thread mill drilling is installed scraper on the shield machine steel work; Not only installation effectiveness is low, and causes damage easily; Because traditional scraper mounting structure is complicated, dismounting inconvenience if therefore tool damage takes place, will greatly influence job scheduling in operation process.
The utility model content
The purpose of the utility model provides a kind of mounting structure of shield machine scraper, and it is complicated to have solved the scraper mounting structure, dismounting inconvenience, the inefficient problem of tool changing.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of mounting structure of shield machine scraper comprises the cutter head body, the scraper pedestal; Shield machine spoke mainboard, said scraper pedestal is fixed on shield machine spoke mainboard, and the cutter head body-fixed is on the scraper pedestal; Cutter head body upper end is equipped with hard alloy blocks; It is characterized in that on the said shield machine spoke mainboard fixed block being arranged, there is the side direction projection said cutter head body rear end; The side direction projection is stuck in the groove of scraper pedestal top, have side by side two bolts penetrate successively behind cutter head body, the scraper pedestal with fixed block through being threaded.
As advancing a preferred version, between said scraper pedestal and the shield machine spoke mainboard headspace is arranged.
As further preferred version, be fixed with the column shaped carbide alloy piece on the said body to the end; An end that exposes at said fixed block is provided with the fabrication hole that is used to dismantle fixed block; Said cutter head body front end also is welded with wearing plate, is threaded with fixed block after passing cutter head body and scraper pedestal behind the said screw bolt passes wearing plate successively.
The utility model adopts the side direction projection on the cutter head body to be installed in the draw-in groove of scraper pedestal; And cutter head body and scraper pedestal are fixed on the fixed block on the shield machine spoke mainboard with two bolts; On fixed block, reserved the fabrication hole that is used to dismantle fixed block; Therefore this mounting structure is not only simple, and convenient disassembly, has improved tool changing efficient and safety.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the sectional drawing of blade construction;
Fig. 2 is blade construction and the part sectioned view of the C of Fig. 1 to view.
Among the figure:
1, hard alloy blocks; 2, cutter head body; 3 wearing plates; 4, headspace; 5, fixed block; 6, shield machine spoke mainboard; 7, bolt; 8, scraper pedestal; 9, side direction projection; 10, column shaped carbide alloy; 11, fabrication hole.
The specific embodiment
Below in conjunction with accompanying drawing, further specify the utility model through embodiment.
Like Fig. 1, shown in Figure 2, a kind of mounting structure of shield machine scraper comprises cutter head body 2; Scraper pedestal 8, shield machine spoke mainboard 6, said scraper pedestal 8 are fixed on shield machine spoke mainboard 6; Cutter head body 2 is fixed on the scraper pedestal 8; Cutter head body 2 upper ends are equipped with hard alloy blocks 1, and on cutter head body 2, are fixed with column shaped carbide alloy in a row 10, and cutter head body front end also is welded with a wearing plate 3; On shield machine spoke mainboard 6, fixed block 5 is arranged; There is side direction projection 9 cutter head body 2 rear ends, and side direction projection 9 is stuck in the groove of scraper pedestal 8 tops, have two bolts 7 to penetrate wearing plate 3, cutter head body 2, scraper pedestal 8 backs and fixed block 5 successively through being threaded side by side.And the end in that fixed block 5 exposes is provided with fabrication hole 11, fixed block 5 for convenience detach.A headspace 4 is arranged, and headspace 4 is bigger than fixed block 5 between fixed block 5 and scraper pedestal 8.
The utility model adopts the side direction projection 9 on the cutter head body 2 to be installed in the draw-in groove of scraper pedestal 8; And cutter head body 2 and scraper pedestal 8 are fixed on the fixed block 5 on the shield machine spoke mainboard 6 with two bolts 7; On fixed block 5, reserved the fabrication hole 11 that is used to dismantle fixed block; Therefore this mounting structure is not only simple, and convenient disassembly, has improved tool changing efficient and safety.
