Abstract
The utility model relates to a sixth-section arm foldable for 180 degrees of a concrete pump truck. The sixth-section arm comprises a sixth-section arm and a link mechanism, wherein the link mechanism comprises a sixth-section arm oil cylinder, a connecting rod I and a connecting rod II; the sixth-section arm foldable for 180 degrees of the concrete pump truck is characterized in that one end of the sixth-section arm oil cylinder is fixed on a fifth-section arm, and the other end of the sixth-section arm oil cylinder is connected with a supporting point of the connecting rod I; one end of the sixth-section arm is respectively connected with a supporting point of the connecting rod II and the fifth-section arm through two pin shafts; and the other supporting point of the connecting rod II is connected with the other supporting point of the connecting rod I, and another supporting point of the connecting rod I is connected with the fifth-section arm. By adopting the sixth-section arm, the space can be fully and effectively utilized, the extension length of the arm support is increased under the condition that the entire length of the concrete pump truck is reduced or unchanged, further, the distribution range is wider, and the arrangement is more flexible.
Description
Technical field
The utility model relates to a kind of the 6th joint arm with collapsible 180 ° concrete mixer.
Background technology
The 6th joint arm of existing six joint arm pump trucks all adopts on arrangement and the parallel arrangement of the 5th joint arm, and the angle of revolution of the 6th joint arm is less than 180 °; Such layout causes, and on pump truck length space, the 5th joint arm and the 6th joint arm length overall are restricted, and the angle of revolution is very little, have wasted the space between the 4th joint arm and the 5th joint arm to a great extent.
Summary of the invention
The purpose of this utility model is in order to overcome problem and the defective that above-mentioned prior art exists, a kind of the 6th joint arm with collapsible 180 ° concrete mixer is provided, the utility model can fully, effectively utilize the space, concrete mixer car load length is reduced or constant situation under increase the jib length of run, and cloth is wider, arranges more flexible.
The technical solution of the utility model is:
The 6th joint arm with collapsible 180 ° concrete mixer, form by the 6th joint arm and linkage, described linkage is made up of the 6th joint arm oil cylinder, connecting rod I and connecting rod II, it is characterized in that: an end of the 6th joint arm oil cylinder is fixed on the 5th joint arm, and the other end links to each other with the fulcrum of connecting rod I; One end of the 6th joint arm links to each other with the 5th joint arm with the fulcrum of connecting rod II respectively by two bearing pins; Another fulcrum of connecting rod II links to each other with another fulcrum of connecting rod I, and another fulcrum of connecting rod I links to each other with the 5th joint arm.
Realize the 5th joint arm and the 6th save arm greater than 180 ° of revolutions; On arranging, the 6th joint arm is arranged in the 5th joint arm below or above.
On arrangement, the connecting rod form is the triangular coupling rod form, comprises on the layout as Fig. 1, Fig. 2, three kinds of arrangements of Fig. 3.
Pump truck behind employing the utility model, owing to effectively utilized the 4th joint arm and the 5th space of saving between the arm, it is longer that jib can be arranged, pump truck design car load layout aspect is played positive role; After adopting linkage, the 6th joint boom slew can be greater than 180 °, and the jib cloth is wider, and is more flexible, effectively improved the cloth performance of pump truck.
In sum, this utility model is a kind ofly can effectively utilize the space, improves pump truck cloth performance, makes simple a kind of novel jib.
Description of drawings
Fig. 1 is the schematic diagram of a kind of case study on implementation of the present utility model.
Fig. 2 is the arrangement diagram of second kind of case study on implementation of the utility model.
Fig. 3 is the arrangement diagram of the third case study on implementation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 1, 2, 3, the utility model is made up of the 6th joint arm 2 and linkage, described linkage is made up of the 6th joint arm oil cylinder 3, connecting rod I 4 and connecting rod II 5, and an end of the 6th joint arm oil cylinder 3 is fixed on the 5th joint arm 1, and the other end links to each other with the fulcrum of connecting rod I 4; One end of the 6th joint arm 2 links to each other with the 5th joint arm 1 with the fulcrum of connecting rod II 5 respectively by two bearing pins; Another fulcrum of connecting rod II 5 links to each other with another fulcrum of connecting rod I 4, and another fulcrum of connecting rod I 4 links to each other with the 5th joint arm 1.
By stretching of the 6th joint arm oil cylinder 3, realize the gyration of the 6th joint arm 2, angle can be greater than 180 °.During folding the placement, the 6th joint arm 2 is placed between the 5th joint arm the 1, the 4th joint arm 6.As shown in Figure 1.During folding the placement, also the 6th joint arm 2 can be placed on the 5th joint arm 1, shown in Fig. 2,3.
