Description
Technical field
The present invention relates to a kind of hydraulic top pushing device, particularly a kind of through spring loaded automatic hydraulic ejection device.
Background technology
The hydraulic ram ejection device is used in the engineering construction field widely in modern times.When utilization hydraulic ram pushing tow technology was passed weight, the oil cylinder back must have the counter-force seat (to be called again: cylinder support) for the oil cylinder piston bar stretches out required support reaction is provided.When the distance of pushing tow is long, need hydraulic ram successively repeatedly the stroke of pushing tow superpose and accomplish omnidistance incremental launching construction task.The stack construction of pushing tow stroke needs repeatedly the cylinder support dismounting, moves forward and installs and fixes, and repeats loaded down with trivial detailsly, consuming time many, and the consumption worker is big.In addition, cylinder support causes the distortion and the wearing and tearing of pushing tow track easily in the process of installing/dismounting repeatedly, and this wearing and tearing also can appear in cylinder support in long-term use, needs regularly to change, thereby has increased the cost of construction.
Summary of the invention
The objective of the invention is in the incremental launching construction that solves longer distance, the problem of the automatic stepping of counter-force seat during hydraulic ram multiple-pass stack operation provides a kind of spring loaded automatic hydraulic ejection device.
The spring loaded automatic hydraulic ejection device that the present invention proposes comprises the base, hydraulic pushing oil cylinder, connecting rod, spring installation, baffle plate and the pushing tow track that are used to deliver weight, wherein:

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
The spring loaded automatic hydraulic ejection device that the present invention proposes comprises the base 1, hydraulic pushing oil cylinder 3, connecting rod 5, spring installation 6, baffle plate 7 and the pushing tow track 8 that are used to deliver weight, wherein:
Pushing tow track 8 both sides are evenly equipped with some protruding 9, and base 1, hydraulic pushing oil cylinder 3 and hydraulic ram bearing 4 all are positioned on the pushing tow track 8, and base 1, hydraulic pushing oil cylinder 3 and hydraulic ram bearing 4 all can move around along pushing tow track 8;
Spring installation 6 is hinged on the hydraulic actuating cylinder bearing 4, and the guiding restriction is arranged on the vertical direction.Be specially: spring 62 is enclosed within on the vertical axle 61, and spring shell 63 entire card are in the vertical groove of hydraulic ram bearing, and spring shell upper end 631 is hinged with hydraulic ram bearing 4, thereby realizes that spring can only move at vertical direction.
The both sides of hydraulic ram bearing 4 install respectively mechanism that two covers are made up of connecting rod 5 and baffle plate 7 in order to respectively with these siding track convexity 9 operational processs in cooperating; Spring in the spring installation 6 is in compressive state and withstands the left upper end 51 of connecting rod 5, fits with the left upper end of the connecting rod 5 that guarantees each mechanism and the surface of baffle plate 7; The left upper end 51 of connecting rod 5 so plays booster action for the connecting rod 5 and the applying of baffle plate 7 than bottom righthand side 52 because quality size differences by gravity has bigger moment of torsion with respect to bearing pin 53.
In operational process, connecting rod 5 can be around bearing pin 53 dextrorotation give part of a turns, and still meeting is because length of spring compressed power and self moment guarantee the surface applying of its left upper end 51 and baffle plate 7 automatically.
The piston rod 2 of hydraulic pushing oil cylinder is hinged with the base 1 that is used to deliver weight, and the spacing between the pushing tow track 8 both sides adjacent protrusion 9 is identical with the stroke of hydraulic pushing oil cylinder 3.
Introduce its pushing tow operation process below in conjunction with the structure of spring loaded automatic hydraulic ejection device, like Fig. 3-shown in Figure 7:
Shown in (a) among Fig. 3, for ejection device just will begin the scheme drawing of a pushing tow task program, its initial position is that the piston rod 2 of hydraulic ram 3 is when just preparing to stretch out.At this moment, bottom righthand side 52 driving surfaces of both sides connecting rod 5 fit with protruding 9 faces in track both sides respectively, and the left upper end 51 and baffle plate 7 bottom surfaces of homonymy connecting rod 5 fit, for stretching out of hydraulic cylinder piston rod 2 provides support reaction.
When if ejection device is started working; The connecting rod 5 and first convexity 9 and baffle-panels are not fitted; (shown in 7 figure e) since the weight of base 1 of delivery weight obviously greater than hydraulic pushing oil cylinder and bearing thereof; So base 1 is as you were when just beginning, but the cylinder body of hydraulic ram 3 and bearing move along track in the opposite direction.
After connecting rod and convexity and baffle-panels applying, hydraulic ram stops reversing sense and moves.Along with the piston rod continuation elongation of hydraulic ram, base 1 beginning of originally static delivery weight is moved along pushing tow track 8 set directions, reaches its predefined range up to hydraulic pushing oil cylinder 3, shown in Fig. 4 (b).
When the piston of pipe bending cylinder shrank gradually, like Fig. 5 (c), connecting rod 5 and then hydraulic ram bearing 4 moved forward synchronously; When connecting rod 5 is run into second convexity 9; Like Fig. 6 (d), the left upper end of connecting rod 5 51 upwards is in the spring of compressive state in the antagonistic spring device 6 and is the center clickwise with bearing pin 53, thereby connecting rod 5 slowly slips over second convexity 9 surface; Almost completely shrink until hydraulic cylinder piston rod 2; Like Fig. 7 (e), this moment, the face of connecting rod 5 and second convexity and baffle plate recovered applying again, thereby had accomplished a pushing tow task program.
Then, can begin the pushing tow operation of next round again.
The automatic ejection device of a kind of spring loaded hydraulic pressure that the present invention provides only needs after assembling of the camp site of pushing gear and debugging; Can get into readiness for operation; Between the incremental launching construction operational period; The counter-force seat does not need to dismantle repeatedly, moves and installs and fixes, and can practice thrift a large amount of man-hours very easy to use and safety.
