Embodiment 1

[0032] Such as figure 1 As shown, a scraper with a buffer structure includes: a support accommodation and cutting system 100, a main cutter body 101, a mounting hole 102, a scraper 103, a cutter body cavity 104, a movable connection shaft 105, a partition 106, and a partition 2 107, limiting prism 108, track one 109;

[0033] Such as figure 1 , figure 2 , image 3 As shown, the main cutter body 101 is an irregular hexagonal prism as a whole, and the upper part is a hollow structure, forming a cutter body cavity 104 for accommodating the scraper 103, the movable connecting shaft 105, the first partition 106, the second partition 107, Restricting edge platform 108, track one 109, buffering and crushing scraper recovery system 110, the remaining part of the main cutter body 101 is a solid body, and the outer surface is provided with mounting holes 102 to be installed on the cutter head;

[0034] Such as figure 1 , image 3 As shown, the scraper 103 includes: a cutting uppe...

Embodiment 2

[0062] Such as Figure 8 As shown, a pipe jacking machine includes the scraper with a buffer structure described in Embodiment 1, and also includes: a cutter head 121, a drive motor 122, a partition 123, a screw conveyor 124, and a belt conveyor 125;

[0063] The cutterhead 121 is positioned behind the cutting surface, the driving motor 122 is positioned behind the cutterhead 121, and is used to provide energy for the rotation of the cutterhead 121, the partition 123 plays a role in supporting other components, and the screw conveyor 124 is positioned behind the cutterhead 121, and the screw conveys Machine 124 conveys the slag that cutterhead 121 cuts off, and belt conveyor 125 is positioned at screw conveyor 124 rear, and the effect of belt conveyor 125 is to transport the obstacle that screw conveyor 124 is carried out.

[0064] The working principle of the present invention:

[0065] When the scraper 103 works and the cut soil becomes hard, the pressure on the scraper 103...

Abstract

The invention relates to the technical field of end shield tunneling machines, in particular to a scraper with a buffering structure and a tube push bench comprising the scraper. The scraper with the buffering structure comprises a supporting, accommodating and cutting system, a main scraper body, mounting holes, the scraper, a scraper body cavity, a movable connecting shaft, a partition plate I, a partition plate II, a limiting prismatic table and a track I, wherein the main scraper body is an irregular hexagonal prism integrally, the upper part is of a hollow structure , forms the scraper body cavity and is used for containing the scraper, the movable connecting shaft, the partition plate I, the partition plate II, the limiting prismatic table, the track I and a buffering and crushing scraper recovery system, the remaining part of the main scraper body is a solid body, and the mounting holes are formed in the outer side face of the remaining part of the main scraper body, so that the remaining part of the main scraper body can be mounted on a cutterhead; the scraper with the buffering structure comprises a cutting upper part and a ssembling lower part, and the whole scraper is in an inverted V shape. According to the scraper with the buffering structure, the tracks, a flexible section, a supporting plate and a spring of a specific track are matched to work, so that the problem that a broken scraper body directly collides with other cutters along with rotation of the cutterhead, and repeated damage is caused is solved.

Description

technical field [0001] The invention relates to the field of pipe jacking machines, in particular to a scraper with a buffer structure and a pipe jacking machine including the scraper. Background technique [0002] A pipe jacking machine is a tunnel boring machine that uses the pipe jacking method. The construction method of pipe jacking is that the "shield" (referring to the supporting segment) of the tunnel is constructed (laid) by the roadheader while excavating, which is different from the open construction method. [0003] The pipe jacking machine is mainly composed of 9 parts, which are shield body, cutter head, double chamber airlock, segment assembly machine, soil dumping mechanism, rear supporting device, electrical system and auxiliary equipment. The cutter head is a cutting disc body with multiple feeding troughs, which is located at the front of the pipe jacking machine, and various knives are installed on it, and the scraper is fixed on the cutter head. It is m...
