Description
Technical field
The utility model relates to the engineering truck field, particularly relates to a kind of jib bracing or strutting arrangement that is used for concreting machinery.In addition, the utility model also relates to a kind of concreting machinery that comprises above-mentioned jib bracing or strutting arrangement.
Background technology
Concrete mixer is the concreting machinery of using always, plays an important role in modern industry.Arm support oil cylinder between the jib of concrete mixer is reached by some joint arms usually, connecting rod, jointed shaft, carrier pipe etc. are formed, and in work progress, be full of concrete in the carrier pipe, utilize jib to drive carrier pipe and reach predetermined height, and, reach the cloth effect under pressure with the output of the concrete in the carrier pipe.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of common concrete mixer in the prior art.
Concrete mixer comprises load-carrying vehicle chassis 15, the structural framing that has been rigidly connected on load-carrying vehicle chassis 15 (claims subframe again, not expression among this figure), be fixed with rotary table 16 on subframe, turntable 13 is installed on the rotary table 16, turntable 13 rotary table 16 relatively turns round, jib 12 is installed on the turntable 13 by hinge, jib 12 generally is made up of 4～5 joint jib structures, and 12 of each adjacent jibs couple together by similar jointed shaft, and the alternate arm shelf structure can rotate mutually.
Under transport condition, jib 12 is supported on the jib bracing frame that is fixed on the subframe.Rotary table 16 is provided with the scalable of two front portions and two rear portions and/or can rotating supporting leg, is separately installed with cylinder apparatus on supporting leg.During work, car load is risen overhead certain distance, support on the ground by cylinder apparatus.Certainly, concrete mixer also comprises some other necessary part, as devices such as concrete pumping device, hopper, carrier pipes, does not describe in detail here.
Common concrete pump truck arm is designed to 3～5 joint arms, and the pump truck of 6 joint arms is also arranged at present.The jib global design for be articulated in get off on, adjacently respectively save employing is parallel to each other between the arm articulated manner and connect.In the course of the work, each jib can be mutually adjusted and launch certain angle to satisfy the needs of real work, the common drive unit that respectively saves the rotation between the arm is an amplitude oil cylinder 11, amplitude oil cylinder 11 by the cylinder bar stretch out or withdraw control jib mutual motion.Consider the reason of actual mismachining tolerance, the design work stroke range of amplitude oil cylinder 11 often is greater than theoretical impulse stroke, be the jib interference problem that prevents to cause thus, often need to install limiting bracket on the jib, make jib also not flexible when extreme position bumps because of amplitude oil cylinder 11, adjacent jib has touched limiting bracket.
Please refer to Fig. 2, Fig. 2 is the structural representation of a kind of typical jib bracing or strutting arrangement in the prior art.
When transport condition, the two joint jibs 12 that the jib bracing or strutting arrangement is supported drop on one high and one low two places of bracing frame respectively.When vehicle was converted to duty, turntable 13 was rotated certain angle according to left side arrow among Fig. 2, problem such as so just may avoid jib 12 and jib bracing or strutting arrangement to produce colliding with.Also must careful operation when reclaiming jib.
In addition, because the characteristics of prior art, when concreting machinery is converted to duty by transport condition, jib 12 must earlier whole certain angle of upwards kicking up after, turntable 13 is behind the low slightly sideway swivel certain angle of jib bracing or strutting arrangement, jib 12 launches, this invisible expansion space of strengthening jib 12; When jib 12 reclaims, then need to do above opposite action.If from the high slightly sideway swivel of jib bracing or strutting arrangement, then jib 12 needs the whole bigger angle of upwards kicking up, otherwise may cause the jib 12 and the part generation of the higher side of bracing or strutting arrangement to interfere, and operator's operative skill is had relatively high expectations.
In addition, said structure has only satisfied in the transport condition the support of jib 12, also need on jib 12 limiting bracket be installed, and does not interfere when guaranteeing that vehicle in working order, has both increased complete vehicle weight, increases cost of production again.
Therefore, how to simplify the structure of concreting machinery, the convenience when improving jib recovery and expansion is the present technical issues that need to address of those skilled in the art.
