Description
technical field:
The utility model belongs to special purpose vehicle production field, relates in particular to a kind of stopping means of operating mechanism of concrete mixer truck.
background technology:
The operating mechanism of concrete mixer truck is direction and the angle of the manual displacement control handle by controlling hydraulic pump, drives hydraulic motor to rotate, then by reductor, finally realizes rotating and the rotating speed increase and decrease of tank body.The operating mechanism that existing market is mainly used is mechanical linkage formula, and is provided with limiting and protecting device, firmly excessive to prevent user, damages the manual displacement control handle of hydraulic pump, and then causes hydraulic pump control valve rotating shaft leakage of oil.Due to the full swing angle difference of the manual displacement control handle of hydraulic pump of different brands model; if BOSCH-REXROTH hydraulic pump is 40 °; Sa hydraulic pump difficult to understand is 30 °; PMH hydraulic pump is 46.8 °; this just requires the stopping means of operating mechanism can adapt to the hydraulic pump of different brands model; the manual displacement control handle that meets hydraulic pump can reach range, can play again position limitation protection effect.
summary of the invention:
The purpose of this utility model is the stopping means that proposes a kind of operating mechanism of simple in structure, the concrete mixer truck that can regulate.
The technical solution of the utility model is achieved in that a kind of stopping means of operating mechanism of concrete mixer truck, comprise fan-shaped positioning disk, limiting plate, driver plate, fixed head, it is characterized in that: the lower end welding driver plate of rotating shaft, is connected with oil pump long draw by bearing pin; Upper end is welded and fixed plate, is connected with fan-shaped positioning disk by bolt; On subframe longitudinal beam, be vertically welded with limiting plate, symmetry is positioned at the left and right sides of rotating shaft, is provided with the hole that bolt can pass through on limiting plate, and the bolt that can regulate stroke is housed on limiting plate.
The utlity model has and make the stroke-limit adjustment of concrete mixer truck operating mechanism simpler, reliable, more advantages of higher of product versatility degree.
brief description of the drawings:
Fig. 1 is the main schematic diagram of the operating mechanism of concrete mixer truck;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is that the A of the utility model structure is to schematic diagram.
In figure: 1. hydraulic motor, 2. hydraulic pump, 3. manually displacement control handle, 4. sebific duct, 5. reductor, 6. oil pump short rod, 7. pivoted arm assembly, 8. mixing drum, 9. oil pump long draw, 10. joystick, 11. rotating shafts, 12. rotating seats, 13. fan-shaped positioning disks, 14. limiting plates, 15. subframe longitudinal beams, 16. driver plates, 17. fixed heads.
detailed description of the invention:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of stopping means of operating mechanism of concrete mixer truck, comprise fan-shaped positioning disk 13, limiting plate 14, driver plate 16, fixed head 17, it is characterized in that: the lower end welding driver plate 16 of rotating shaft 11, is connected with oil pump long draw 9 by bearing pin; Upper end is welded and fixed plate 17, is connected with fan-shaped positioning disk 13 by bolt; On subframe longitudinal beam 15, be vertically welded with limiting plate 14, symmetry is positioned at the left and right sides of rotating shaft 11, is provided with the hole that bolt can pass through on limiting plate 14, and the bolt that can regulate stroke is housed on limiting plate 14.
Embodiment: hydraulic motor 1, reductor 5, mixing drum 8 are bolted together, hydraulic motor 1 is connected by sebific duct 4 with hydraulic pump 2.The manual displacement control handle 3 of hydraulic pump 2 is connected with oil pump short rod 6 by bolt, oil pump short rod 6 is connected with pivoted arm assembly 7 by bolt, rotating shaft 11 is connected with oil pump long draw 9 by bolt, oil pump long draw 9 is connected with pivoted arm assembly 7 by bolt, rotating shaft 11 and rotating seat 12 are by being welded to form parts, joystick 10 is connected with rotating seat 12 by bearing pin, has so just formed the operating mechanism of a trucd mixer.
The driver plate 16 of the lower end welding of rotating shaft 11 is connected with oil pump long draw 9 by bearing pin, the fixed head 17 of the upper end welding of rotating shaft 11 is connected with fan-shaped positioning disk 13 by bolt, rotating shaft 11 each side have a limiting plate 14, limiting plate 14 is welded on subframe longitudinal beam 15, and the bolt that can regulate stroke is housed on limiting plate 14.
In the time carrying out system installation, operator is respectively according to B in Fig. 1, the direction of C is pulled joystick 10, make the manual displacement control handle 3 of hydraulic pump 2 reach range at positive and negative both direction, now fan-shaped positioning disk 13 is followed rotating shaft 11 together at B, C both direction rotates certain angle, now adjust respectively the extension elongation of two bolts on limiting plate 14, and withstand fan-shaped positioning disk 13, just can realize the manual displacement control handle 3 that meets hydraulic pump 2 and can reach range, can play again position limitation protection effect, for the hydraulic pump 2 of different brands model, only need to adjust the overhang of the bolt on limiting plate 14, make operating mechanism adjustment simpler, reliably, product versatility degree is higher.
