Problems solved by technology

[0006] Although the above types of paver can achieve wider or zero-gap paving, but limited by the size of the frame, if the horizontal dimension is too long, there will be instability when many tooling parts are installed, and when paving The components are installed at the end of the rack, and because the material conveying distance is too long, segregation is also prone to occur

Embodiment 1

[0026] Such as figure 1 , figure 2 and image 3 As shown, the double telescopic frame 1 of the present embodiment includes a front beam 10, a rear beam 11, and side beams 12 installed on the left and right ends of the front beam 10 and the rear beam 11 to connect the front beam 10 and the rear beam 11. For ease of description, the direction parallel to the front beam 10 is defined as the transverse direction, and the direction parallel to the side beam 12 is defined as the longitudinal direction.

[0027] The front beam 10 in this embodiment is provided with a sliding sleeve type telescopic part (unlabeled) controlled by a hydraulic cylinder, and the rear beam 11 is also provided with a sliding sleeve type expansion part (unlabeled) controlled by a hydraulic cylinder. The sliding sleeve type telescopic part includes relatively movable inner and outer sliding sleeves and a hydraulic cylinder (not shown) that controls the lateral relative movement of the inner and outer slidi...

Embodiment 2

[0030] Such as Figure 4Shown is the double telescopic frame of Embodiment 2 of the present invention. The difference between Embodiment 2 and Embodiment 1 is that: an auxiliary side beam 12' is installed on the outside of the side beam 12, the structure of the auxiliary side beam 12' is the same as that of the side beam 12, and the first auxiliary side beam 12' is installed inside the auxiliary side beam 12'. The extension section 121' is installed on the free end of the first auxiliary extension section 121' through a flange connection with the installation column 2 of the crawler-type traveling device 3, and the first auxiliary extension section 121' can be mounted on the auxiliary side beam 12' The inner portion is extended or contracted longitudinally, and the expansion and contraction of the first auxiliary extension section 121' can also be controlled by a hydraulic cylinder or a screw rod. When the side beams 12 and the auxiliary side beams 12' are all extended, the d...

Embodiment 3

[0034] Such as Figure 8 As shown, the difference between embodiment 3 and embodiment 2 is that: the outer wall of the side beam 12 is equipped with a secondary side beam 12 ′ whose expansion and contraction direction is opposite to the expansion and contraction direction of the side beam 12 , and a first auxiliary extension The long section 121', the second auxiliary extension section 122' is installed in the first auxiliary extension section 121', and the installation column 2 on which the crawler-type traveling device 3 is installed is installed on the second auxiliary extension section 122' through flange connection The free end of the first sub-extension section 121' can be longitudinally elongated or contracted in the sub-side beam 12', and the second sub-extension section 122' can be longitudinally elongated in the first sub-extension section 121' or shrink. The structure and installation method of the auxiliary side beam 12', the first auxiliary extension section 121'...

Abstract

A double telescopic frame and a paver, the paver includes a main frame, a paving slab installed under the main frame, and a material distribution device installed in front of the paving slab on the main frame, the main frame is a double telescopic frame , the double telescopic frame includes: front beam, rear beam, side beam connecting the front beam and the rear beam, and the walking device supporting the double telescopic frame; An extension section, a second extension section that can move longitudinally is arranged in the first extension section, and the walking device is arranged at the free end of the second extension section; a reinforcing link is hingedly installed on the second extension section , the other end of the reinforced connecting rod is hingedly installed on the front beam. The main frame of the present invention is a double-telescopic frame in the longitudinal direction, which can effectively increase the longitudinal length of the frame. When paving large-scale and wide widths, the frame has better stability and is conducive to improving the quality of paving.

Description

technical field [0001] The invention belongs to the field of road construction machinery, in particular to a material paver and a paver frame. Background technique [0002] In recent years, China's road construction projects have been increasing, mainly in the construction of first-class roads, expressways and other grades of roads. These roads are wide, and the construction units have high quality requirements, requiring full-width or half-width paving at one time. At present, it is basically impossible to produce large-scale paving machines in China. The construction unit can only use two pavers to pave together. The use of two pavers not only doubles the purchase cost, but also doubles the loss when the machine is worn out, which makes the engineering cost of the construction unit unable to be effectively reduced. As a result, domestic construction units have increasingly strong demand for large pavers on wide roads. [0003] The Chinese utility model patent No. 0026085...
