Embodiment Construction

[0015] The positioning and installation method of the cutter seat of the cutter suction dredger according to the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention cannot be limited thereby.

[0016] Such as figure 1 As shown, grooves are provided at both ends of the dummy shaft 1 to install a pair of limit blocks 2. After the dummy shaft 1 is assembled with the left and right reamer seats 4, each pair of limit blocks 2 is respectively located on the shaft of the corresponding reamer seat 4. On both sides of the hole, the distance between the left and right reamers 4 is controlled by two pairs of limit blocks 2; four jacks 3 for lever insertion are processed on the craft dummy shaft 1, and the jack 3 can be inserted into the lever at any time, and the test Whether the process dummy shaft 1 rotates smoothly or not, its effect is equal to the normal...

Abstract

The invention discloses a positioning installation method of cutter seats of a cutter-suction dredger, which comprises the following steps of: finishing the fine finishing of the axle holes of the cutter seats in a workshop, and additionally processing a technical dummy spindle, wherein the size of the matched position of the technical dummy spindle and the axle holes conforms to the design tolerance of a cutter girder; after the technical dummy spindle and the two cutter seats are assembled, placing the two cutter seats on a deck, finely adjusting the positions of the two cutter seats while rotating the technical dummy spindle, and positioning the cutter seats through spot welding after the dummy spindle is rotated smoothly; respectively welding one bottom edge corresponding to the two cutter seats, then rotating the dummy spindle, welding the other bottom edge corresponding to the two cutter seats if the dummy spindle is rotated smoothly, and repeatedly operating until welding is finished; and if any two bottom edges are welded and the dummy spindle can not rotated smoothly, welding the other side corresponding to the welded bottom edge of the cutter seats to correct a positional deviation until the dummy spindle is rotated smoothly, and finishing welding according to the previous working procedure. The positioning installation method has simple process and can markedly improve the work efficiency and ensure the installation accuracy.

Description

technical field [0001] The invention relates to a cutter seat of a dredger, in particular to a method for installing the cutter seat. Background technique [0002] A very long swingable cutter arm is hinged on the deck of the cutter suction dredger, and the front end of the cutter arm is equipped with a reamer. There is a reamer beam (hinge shaft) at the rear end of the reamer arm, which is installed on the left and right reamer seats on the deck. The arm of the reamer swings down to make the reamer touch the bottom of the river, agitate the sediment at the bottom of the river, and suck out the sediment. After the operation is finished, the reamer arm swings upward to raise the reamer. Since the reamer may touch hard gravel when working on the bottom of the river, the reamer arm will vibrate greatly, so the assembly precision of the reamer beam and reamer seat is required to be high, otherwise the reamer beam and reamer seat will be aggravated. wear and reduce service li...
