The utility model content
In order to overcome the deficiency that has material distributing machine now, the utility model provides a kind of material distributing machine of three arms joint combination relative motion, and the jib that solve traditional material distributing machine can not carry out pitching and the interior technical problem of turning round two kinds of motions of horizontal plane in the vertical plane simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of material distributing machine of three arms joint combination relative motion, comprise the body of the tower bearing and with the parallel connected boom system of concrete pumping pipeline, the head end of boom system is rotationally connected by the first horizontal rotation mechanism and body of the tower bearing horizontal rotation, the concrete pumping pipeline comprises feed pipe and discharging mouth, it is characterized in that: above-mentioned boom system is by big arm, middle arm and three sections relative motions of forearm are connected from beginning to end and form, the end of big arm is rotationally connected by the head end horizontal rotation of the second horizontal rotation mechanism and middle arm, the end of middle arm is rotationally connected by the head end of luffing mechanism and forearm, and the end of forearm is connected with the discharging mouth.
The described second horizontal rotation mechanism comprises that one is fixedly connected on motor, reductor and the transmission mechanism of big arm end, and the output of reductor drives and connects the tooth axle, the pivoting support during the tooth axle drives again and is fastened on the arm.
Described luffing mechanism comprises oil cylinder, centering block and push rod, the bottom of arm during wherein oil cylinder one end is hinged on, the other end is connected with the rear end of centering block, and the middle and lower part of centering block is connected with the rear end of push rod, the end of arm during the front end of centering block is hinged on, the front end of push rod is connected with the head end of forearm again.
Described tooth axle is supported on the big arm by bearing and sleeve.
The beneficial effects of the utility model are as follows:
The means that the utility model adopts horizontal rotation to combine with pitching between the material distributing machine jib, horizontal operation and vertical operation are organically combined, the advantage of melting existing two kinds of material distributing machine, improved the single operation form of material distributing machine jib, can fundamentally solve the drawback of the material distributing machine existence of above-mentioned two kinds of patterns, neither be subjected to the restriction of site operation region height when making material distributing machine work, can solve concrete again effectively and wait the problem that has a strong impact on concrete pouring quality because of drop produces segregation than Da Yi.The utility model can be guaranteed concrete pouring quality applicable to the cast-in-situ concrete cloth of building high-speed railway, 32 meters large scale prefabricated box beams of Line for Passenger Transportation or building.
