Abstract

The invention provides a concrete distributor with an arm support capable of both horizontal rotation and pitching movement. The concrete distributor comprises a tower body support and an arm support system connected in parallel with a concrete pumping pipeline. The head end of the arm support system is rotationally connected with the tower body support in horizontal rotation manner via a first horizontal rotation mechanism. The concrete pumping pipeline comprises a feeding pipe and a discharge nozzle. The arm support system is formed by the tail-to-head connection of a large arm, a middle arm and a small arm, which are in relative movement to one another. The tail end of the large arm is rotationally connected with the head end of the middle arm in horizontal rotation manner via a second horizontal rotation mechanism. The tail end of the middle arm is rotationally connected with the head end of the small arm via a pitching mechanism. The tail end of the small arm is connected with the discharge nozzle. Since the arm support system is capable of both horizontal rotation and pitching movement, the concrete distributor incorporates the horizontal operation and the vertical operation, integrates the advantages of the prior two types of concrete distributors, improves the single operation mode of the prior concrete distributor, and substantially overcomes the problems of the prior two types of concrete distributors.

Description

The material distributing machine that the jib horizontal rotation combines with elevating movement
Technical field
The present invention relates to a kind of concrete distributing construction machinery.
Background technology
Concrete spreader is the apparatus for distributing that the concrete pumping pipe end carries out concrete pouring, it can improve effectively concreting efficient, improving the quality of concreting, promote civilized construction, is indispensable corollary equipment in the concrete pumping operation.
Known concrete spreader divides two kinds according to the action scheme of jib: a kind of be jib can before and after stretch, jib can pitching in vertical plane between relatively, but in horizontal plane, there is not relative motion, slew gear in the complete machine horizontal plane has only one, is located at the root and the body of the tower upper bracket junction of jib; Another pattern is that complete machine has two joint jibs, and each jib all can not pitching, can only turn round in horizontal plane, and two slew gears are arranged, and can only do relative motion between the jib in horizontal plane.
At present, in building constructions such as high-speed railway and Line for Passenger Transportation, often run into the concreting of large scale prefabricated box beam more than 30 meters, in order to ensure concrete pouring quality, unit in charge of construction racks one's brains when selecting material distributing machine, and in use all there is very big defective in the material distributing machine of existing two kinds of patterns, and first kind of material distributing machine jib can not the pitching operation, height to the operating area has certain requirement, and material distributing machine just can't be used when the operation zone is low; Second kind of material distributing machine is because jib can only horizontal balance, and when the scope of operation was low, the normal throw of concreting was too big, and concrete is easy to generate segregation, can not guarantee the quality of concreting.
Summary of the invention
In order to overcome the deficiency of existing material distributing machine, the invention provides the material distributing machine that a kind of jib horizontal rotation combines with elevating movement, 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 solution adopted for the present invention to solve the technical problems is:
The material distributing machine that a kind of jib horizontal rotation combines with elevating movement, 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 tooth axle is supported on the big arm by bearing and sleeve.
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.
Beneficial effect of the present invention is as follows:
The means that the present invention 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 present invention can guarantee 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.
