Description of drawings
Fig. 1 is the structural representation of the utility model crane span structure hoisting system.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
See also Fig. 1, the crane span structure hoisting system of a kind of dredge boat of the utility model, mainly comprise quiet assembly pulley 1, wirerope 2, running block 3, swing upending frame 4, hydraulic jack 5, diaphragm accumulator 6, door frame 7, crane span structure 8, air pump 51, hydraulic cylinder piston rod 52 and fluid pressure line 53, described diaphragm accumulator 6 further comprises hydraulic oil end 62 and compressed air end 61; Described crane span structure hoisting system also comprises the reamer that is used to dredge, and it is installed in the head of crane span structure 8, and described crane span structure hoisting system also comprises the winch that is installed on the main hull, and described winch also further comprises motor and wirerope 2.
The otic placode group is housed on the door frame 7, and quiet assembly pulley 1 is installed on the door frame 7 by the otic placode group; On the swing upending frame 4 the otic placode group is housed also, running block 3 is installed on the swing upending frame 4 by the otic placode group; One end of wirerope 2 is connected on the winch, the quiet assembly pulley 1 that the other end passes on the door frame 7 couples together with the running block of swinging on the upending frame 43, form the assembly pulley hoisting system, the user can come folding and unfolding wirerope 2 by the motor that starts winch, and then can drive the lifting of swing upending frame 4.
Two hydraulic jacks 5 are symmetrically distributed on the swing upending frame 4, and the piston rod 52 of hydraulic jack 5 is hinged by the otic placode group and the crane span structure 8 that are arranged on the crane span structure 8 upside down, thereby realize the flexible connection of swing upending frame 4 and crane span structure 8.
Diaphragm accumulator 6 is installed on the crane span structure 8, fluid pressure line 53 1 ends communicate with the hydraulic oil end 62 of diaphragm accumulator 6, be connected on the rod chamber oil circuit of fluid pressure line 53 other ends and hydraulic jack 5, realize that hydraulic oil is mobile between hydraulic jack 5 and diaphragm accumulator 6; The compressed air end 61 of diaphragm accumulator 6 is by compressed air hose and the air pump 51 that is installed on the main hull, and air pump 51 can be 61 inflation and the pressure regulation of compressed air end.
When dredge boat is started working, earlier diaphragm accumulator 6 is linked air pump 51, for the compressed air end 61 of diaphragm accumulator 6 charges into high pressure nitrogen or pressure-air, the pressure of high pressure nitrogen or pressure-air can be regulated by air pump 51; Simultaneously, the hydraulic oil end of diaphragm accumulator 6 and the rod chamber oil circuit of hydraulic jack 5 are connected by fluid pressure line 53, and adjust oil pressure, make hydraulic oil end 62 pressure of diaphragm accumulator 6 suitable with compressed air end 61 pressure; During actual the use, can adjust the setting pressure on the diaphragm accumulator 6 in advance according to different soil properties, thereby adjust the ground pressure of crane span structure 8 end reamers.
Dredge boat is operation on the water, when wave sinks the formation trough, boats and ships also can be along with wave sinks together, the reamer that causes crane span structure 8 ends is with the mud surface contact pressure is excessive under water, the load of hydraulic jack 5 reduces, pressure in the hydraulic jack 5 diminishes, because hydraulic jack 5 communicates with the hydraulic oil end 62 of diaphragm accumulator 6 by fluid pressure line 53 1 ends, make compressed air end pressure in the diaphragm accumulator 6 be higher than the pressure in the hydraulic jack 5, diaphragm accumulator 6 is by fluid pressure line 53 beginning repairings in hydraulic jack 5, make oil cylinder piston bar 52 and hydraulic jack 5 move toward one another, make hydraulic jack 5 shrink, thereby the reamer ground pressure that reduces crane span structure 8 ends reach the equalization point of prior setting.When wave up gushes the formation crest, the reamer and the mud surface contact pressure of crane span structure 8 ends are too small, hydraulic jack 5 loads increase, it is big that pressure in the hydraulic jack 5 becomes, make compressed air end pressure in the diaphragm accumulator 6 be lower than the pressure in the hydraulic jack 5, the oil in the hydraulic jack 5 is got back in the diaphragm accumulator 6 by fluid pressure line 53, makes oil cylinder piston bar 52 and hydraulic jack 5 counter motions, hydraulic jack 5 is stretched out, and the reamer ground pressure that increases crane span structure 8 ends reaches the equalization point of setting.
Dredge boat is when work, because hydraulic jack 5 cylinder bodies are fixedlyed connected with swing upending frame 4, when wave sinks the formation trough, the piston rod 52 of hydraulic jack 5 shrinks, thereby can balance crane span structure 8 and the reamer of crane span structure 8 leading sections, make reamer keep constant with the relative position of work plane silt; When wave up gushes when forming crest, the piston rod 52 of hydraulic jack 5 stretches out, also can balance crane span structure 8 and the reamer of crane span structure 8 leading sections, and make reamer keep constant with the relative position of work plane silt.When needs promote the earth dig, only need tighten up the wirerope 2 on the winch by starting winch motor, can will dig earth steadily, hoist apace.
The crane span structure hoisting system of this dredge boat also can be used for bucket-wheel suction dredger and chain type dredge boat etc.
The utility model is owing to used hydraulic jack 5 and diaphragm accumulator 6 in the crane span structure hoisting system of dredge boat, make this system have the compensation of undulation function, solved the deficiency that conventional crane span structure system can't compensate the hull wave action, can increase the efficient of dredge boat when the wave operation, form is reliable, simple to operate.
The above only is a better embodiment of the present utility model; protection domain of the present utility model does not exceed with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
