Abstract
The utility model discloses a shield machine with a function of crushing a large boulder. The part of crushing the large boulder is composed of a cutter head spoke (1), a hydraulic hammer (2), a sealing ring (3), an installation sleeve (4), a sealing gasket (5), an inner hexagon screw (6), a spring wafer (7), an installation seat (8), a hydraulic oil pipe (9) and a central revolving joint (10). During tunneling of an earth pressure balanced shield machine or a slurry balanced shield machine in sandy cobble stratum, when the boulder is confronted in front of a cutter head and has a particle size larger than the diameter of the largest opening of the cutter head and a cutter cannot crush the boulder, the cutter head spoke (1) turns an angle to reach a region on which the large boulder is located, and the hydraulic hammer (2) extends and props against the large boulder for crushing. With the adoption of the function of crushing the large boulder, the shield machine which is already produced or used but does not have the function can be improved and upgraded, and the problem of smooth tunneling of the shield machine in the sandy cobble stratum can be effectively solved.
Description
Technical field
The present invention relates to the realm of building construction, be mainly used in the open type shield machine in the constructing tunnel.
Technical background
In shield construction, if earth pressure balance shield machine or slurry-water balance type shield machine tunnel in sand-pebble layer, when cutterhead the place ahead run into particle diameter greater than the erratic boulder of cutterhead maximum open diameter but can't be broken situation the time; The erratic boulder of big particle diameter possibly rotate even the holding cutterhead with cutterhead; Bring many difficulties that are difficult to overcome to driving, increase cutter, cutterhead serious wear like required torque, thrust; The processing cost of big particle diameter cobble is big; Sedimentation is out of control, and the duration is delayed, cost increase etc.How fast, safety, the erratic boulder of broken big particle diameter effectively, become a difficult point of shield-tunneling construction.
Summary of the invention
The utility model provides the shield machine with broken big erratic boulder function, and the erratic boulder of broken big particle diameter carries out driving smoothly effectively.
The part of the big erratic boulder function of fragmentation of the present invention is made up of cutterhead spoke (1), hydraulic hammer (2), sealing ring (3), installing sleeve (4), sealing mat (5), soket head cap screw (6), spring washer (7), mount pad (8), hydraulic oil pipe (9) and centre revolving joint (10).Installing sleeve (4) is complementary with the size of cutterhead spoke (1) and hydraulic hammer (2), and hydraulic hammer (2) front portion places in the installing sleeve (4).Sealing ring (3) places in the annular groove of installing sleeve (4), the gap between sealing ring (3) radial seal installing sleeve (4) internal diameter and hydraulic hammer (2) external diameter.Mount pad (8) is complementary with the size of hydraulic hammer (2), and the rear portion of hydraulic hammer (2) places in the mount pad (8).One of hydraulic oil pipe (9) terminates on the hydraulic hammer (2), and the other end is connected on the centre revolving joint (10).Installing sleeve (4) is fixed on the cutterhead spoke (1).Mount pad (8) and sealing mat (5) are fixed on the cutterhead spoke (1) through soket head cap screw (6) and spring washer (7).The cutterhead spoke (1) of shield machine is gone up the device with broken big erratic boulder function is installed.
Shield machine is in containing the sand-pebble layer driving of big erratic boulder; The particle diameter that runs into erratic boulder when cutterhead the place ahead can't get into Tu Cang and when can't be by cutter broken greater than cutterhead maximum open diameter; Cutterhead spoke (1) rotates an angle and arrives big erratic boulder region; The tup that is installed in the hydraulic hammer (2) on the cutterhead spoke (1) stretches out, pushes against big erratic boulder and carries out fragmentation, till rubble can get into native storehouse.
The utility model provides the shield machine with broken big erratic boulder function; Broken big erratic boulder function that this shield machine had also can be to producing or using but the shield machine that do not possess this function carries out transformation and upgrade; Transformation is convenient, cost is low, can solve the problem that shield machine tunnels in containing the sand-pebble layer of big erratic boulder smoothly effectively.

The specific embodiment
Shield machine in the present embodiment with broken big erratic boulder function; The structure chart of the part of its broken big erratic boulder function is as shown in Figure 1, and it comprises cutterhead spoke (1), hydraulic hammer (2), sealing ring (3), installing sleeve (4), sealing mat (5), soket head cap screw (6), spring washer (7), mount pad (8), hydraulic oil pipe (9) and centre revolving joint (10).During normal the driving, hydraulic hammer (2) is retracted in installing sleeve (4) inside, is in off working state.The size that the external diameter of installing sleeve (4) and cutterhead spoke (1) are gone up installing hole is complementary, and installing sleeve (4) integral solder is on cutterhead spoke (1).The front portion of hydraulic hammer (2) places in the installing sleeve (4), and the rear portion of hydraulic hammer (2) places in the mount pad (8).Mount pad (8) and sealing mat (5) are fixed on the cutterhead spoke (1) through soket head cap screw (6) and spring washer (7) or other modes.One of hydraulic oil pipe (9) terminates on the hydraulic hammer (2), and the other end is connected on the centre revolving joint (10).The position distribution of hydraulic hammer (2) such as Fig. 2, shown in Figure 3, the position of hydraulic hammer (2) and quantity are different and different according to the cutter head of shield machine structure: cutter diameter is big more, and the quantity of hydraulic hammer (2) is just many more; Cutterhead maximum open diameter is big more, and the quantity of hydraulic hammer (2) is just few more.Spaced radial and cutterhead maximum open diameter between the hydraulic hammer (2) are proportional; Decide according to the layout of cutter and inlet (being used to add swell soil, mud or foam etc.) position of hydraulic hammer (2) on cutterhead spoke (1); Be as the criterion not interfere; Hydraulic hammer (2) can place on the same cutterhead spoke (1), also can place on the different cutterhead spokes (1).
When shield machine passes through sand-pebble layer; If in tunneling process, run into the erratic boulder of particle diameter greater than cutterhead maximum open diameter, cutter can't carry out fragmentation to it sometimes, and this will cause big erratic boulder can not get into Tu Cang; Big erratic boulder may rotate even the holding cutterhead with cutterhead; Make cutterhead moment of torsion and cylinder thrust all increase, not only can the heavy wear cutterhead, cutter, and shield machine can't be tunneled forward.At this moment, stop the rotation of cutterhead, in the control room, send instruction the tup of hydraulic hammer (2) is stretched out.If the tup of hydraulic hammer (2) does not touch big erratic boulder, oil pressure changes little so.If the contact of the tup of hydraulic hammer (2) has also pushed against big erratic boulder, oil pressure has significantly so increases, and stops the propelling of hydraulic hammer (2) tup, starts the impact rubble function of hydraulic hammer (2), and big erratic boulder is carried out fragmentation.If having stretched out the distance of setting, the tup of hydraulic hammer (2) also do not touch big erratic boulder; Then regain hydraulic hammer (2) tup; Stretch out hydraulic hammer (2) tup again after cutterhead turned an angle; Repeat above-mentioned action, till big erratic boulder and fragmentation that all obstruction shield machines that find cutterhead the place ahead advance.If big erratic boulder rotates with cutterhead, can let hinged oil cylinder reclaim certain distance, the pulling cutterhead is retreated, and big erratic boulder is separated with cutterhead, repeats above action rubble again.After rubble is accomplished, the cutterhead normal rotation, shield machine continues to push ahead.
