Below in conjunction with the specific embodiment the utility model is done to describe in further detail.
As shown in Figure 1; The adjustable high-speed hydraulic rammer compacter of the separate type stroke of the utility model comprises and rams frame 15, rammer pin 14, hammer ram 16 and hydraulic cylinder 12, hydraulic control circuit, upper stroke switch, lower stroke switch, electric control loop (said hydraulic control circuit, upper stroke switch, lower stroke switch, electric control loop all do not draw in the accompanying drawing).
The top of said hammer ram 16 is provided with a cavity; Be provided with the locking of cover cam-type and relieving mechanism 13 in the said cavity; Said cam-type locking is fixed on the said hammer ram 16 through installing component with relieving mechanism 13; As shown in Figures 2 and 3, said installing component comprises cam mounting seat 8, cam installing plate 11 and upper cover plate 10.
As shown in Figure 2; Said cam-type locking comprises 1,2, two torsion springs 3 of a pair of eccentric cam and two camshaft shift forks 5 with relieving mechanism 13; Said a pair of eccentric cam is made up of with right cam 2 left cam 1; Left side camshaft line is parallel with right camshaft line, and two torsion springs 3 are set on each camshaft, described two torsion springs 3 and described left cam 1 and right cam 2 camshaft axially on the location all be through axle sleeve structure (referring to cam sleeve among Fig. 26 and torsion spring axle sleeve 4); As shown in Figures 2 and 3; One end of two torsion springs 3 is fixed with the camshaft at place respectively; Two camshaft shift forks 5 all are V-shape; One end of two camshaft shift forks 5 is fixed with the other end of two torsion springs 3 respectively, and the other end of two camshaft shift forks 5 is the trigger ends that lay respectively at a pair of eccentric cam outer upper;
As shown in Figure 1, the bottom of hydraulic cylinder piston rod 17 is provided with a connector 7, and is as shown in Figure 2; Be provided with a circle arc-shaped groove that aligns in the axial direction on the outer surface of revolution of said left cam 1 and right cam 2 respectively; Thereby between said left cam 1 and right cam 2, form the passage of a vertical direction, as shown in Figure 4, said passage and said connector 7 align at vertical direction; Said upper cover plate 10 is provided with and is used for the through hole that connector 7 passes through, and is as shown in Figure 4.Said connector 7 triggers described upper stroke switch and lower stroke switch respectively when two extreme positions up and down.
As shown in Figure 1; Said rammer frame 15 is provided with two shift fork push rods 9 on the vertical direction; Said two shift fork push rod 9 in the vertical directions align with the trigger end of said two camshaft shift forks 5, and said upper cover plate 10 is provided with and is used for the through hole that shift fork push rod 9 passes through, and is as shown in Figure 5.Said two shift fork push rods 9 all are fixed on through a bracing frame and ram on the frame 15; The installation site of shift fork push rod 9 on rammer frame 15 determined the impulse stroke of hammer ram 16; Therefore; The upper-lower position of shift fork push rod 15 is adjustable, can realize many tonnages grade compacting ability through regulating shift fork push rod 9 in the setting height(from bottom) of ramming on the frame 15.
Between said cam-type locking and relieving mechanism and the hammer ram for removably connecting.Between described connector 7 and the described piston rod 17 for removably connecting.The cam-type locking that forms thus in the utility model is an independent agency with relieving mechanism 13 and connector 7 respectively, can quick and convenient carry out repair and replacement, can shorten the maintenance time when breaking down because of cam mechanism.
In addition, consider that hydraulic cylinder 12 drive connectors 7 are to be in Light Condition when moving downward,, shorten the lost motion time, increase work efficiency so can adopt speedup hydraulic circuit simple in structure to improve the lost motion movement velocity.
The operating principle of the utility model separate type stroke is adjustable high-speed hydraulic rammer compacter is: adopt camlock and relieving mechanism to realize the locking and the release of hydraulic cylinder 12 and hammer ram 16; Promptly in the lifting process of hammer ram 16, hydraulic cylinder 12 is to link together through the connector 7 that a pair of eccentric cam locking is positioned at piston rod 17 bottoms with hammer ram 16; In hammer ram 16 landing processes, because this a pair of eccentric cam opens, discharge connector and hydraulic cylinder 12 is separated with hammer ram 16, hammer ram 16 impacts the bottom surface through the gravity free-falling, and the completion single is rammed action.According to the requirement of construction, through regulating the installation site of shift fork push rod 9, can control the impulse stroke of hammer ram 16, ram energy thereby be implemented on the rammer compacter output difference, accomplish the task of ramming of different tonnage grades and the broken task of different tonnage grades.
The utility model separate type stroke is adjustable when the high-speed hydraulic rammer compacter is in free state, and as shown in Figure 3, torsion spring 3 has certain pretightning force, and the left cam 1 and the right cam 2 of two off-centre are in clamped condition under torsion spring 3 pretension effects.
When piston rod 17 these connectors 7 of drive moved downward, connector 7 backed down the left cam 1 and right cam 2 of two off-centre, and located through left cam 1 and the arc-shaped groove in the middle of the right cam 2; After piston 17 drive connectors 7 are inserted into eccentric left cam 1 and the arc-shaped groove certain position between the right cam 2; Trigger lower stroke switch, the switching-over of hydraulic system oil circuit, hydraulic cylinder 12 drives connector 7 and moves upward; This moment is because the pretension effect of torsion spring 3; The eccentric left cam that is provided with 1 clamps connector 7 with right cam 2, and moves upward along with hydraulic cylinder 12 drives connector 7, and eccentric left cam 1 with connector 7 self-locking will take place with right cam 2; Realize the lifting of hammer ram 16, as shown in Figure 4.
When hammer ram 16 when locking is thus lifted to certain altitude with relieving mechanism 13 with cam-type, camshaft shift fork 5 comes in contact with being installed in the shift fork push rod 9 that rams on the frame 15, and camshaft shift fork 5 drives eccentric left cam 1 and right cam 2 backward rotation; Make two eccentric left cam 1 and the eccentric spacings between the right cam 2 become big, at this moment, self-locking is eliminated; As shown in Figure 5, left cam 1 separates with connector 7 with right cam 2, and 16 of hammer rams land under the effect of gravity and ram pin 14; Connector 7 triggers upper stroke switch simultaneously; The switching-over of hydraulic system oil circuit, hydraulic cylinder 12 drives connector 7 and moves downward, and begins next operation cycle.
Although top combination figure is described the utility model; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Under the situation that does not break away from the utility model aim, can also make a lot of distortion, these all belong within the protection of the utility model.
