The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
As shown in Figure 1, according to the winding plant of steel rope of the present utility model, comprise: reel 10 and hydraulic control circuit, this hydraulic control circuit comprises Hydraulic Pump 13, this Hydraulic Pump 13 by directional control valve 14 with for driving the HM Hydraulic Motor 11 of reel 10 to be connected, described hydraulic control circuit also comprises back pressure component 12, this back pressure component 12 is arranged in the oil return line of hydraulic control circuit when reel 10 discharges steel rope, can provide back pressure and only allow the hydraulic oil that comes from directional control valve 14 to flow to HM Hydraulic Motor 11 during when reel 10 Wound steel rope when reel 10 discharge steel rope.
In hydraulic control circuit, Hydraulic Pump 13 is for pump pressure power fluid force feed, and be connected with HM Hydraulic Motor 11 by directional control valve 14, and then can drive reel 10 to rotate along two contrary directions by HM Hydraulic Motor 11, thus realize coiling and the release of 10 pairs of steel ropes of reel.Accordingly, the reel coordinating with this reel 10 is respectively and discharges and reel the operation of steel rope.
Different from the winding plant of traditional steel rope is, in stating hydraulic control circuit, be provided with back pressure component 12, this back pressure component 12 is arranged in the oil return line when reel 10 discharges steel rope, thereby can play the slow effect of resistance to the hydraulic oil being back in fuel tank when reel 10 discharges steel rope; And when reel 10 Wound steel rope, only allow (power) hydraulic oil that comes from directional control valve 14 to flow to HM Hydraulic Motor 11, thereby can not produce to steel rope elevator device any interference or adverse effect when the Wound steel rope.
Therefore, according to the technical solution of the utility model, when 10 pairs of steel ropes of reel discharge, during especially passive release, due to the setting of above-mentioned back pressure component 12, can slow down the release rate of steel rope, thereby can make steel rope obtain enough tensile forces, and then make to coordinate with this reel 10 reel of the operation of reeling when reeling, to there will not be the situation of disorder cable, realize the purpose of this utility model.
As shown in Figure 1, directional control valve 14 comprises the first actuator port 141 and the second actuator port 142, HM Hydraulic Motor 11 comprises the first actuator port A and the second actuator port B, the first actuator port 141 of directional control valve 14 is connected in the first actuator port A of HM Hydraulic Motor 11 by the first hydraulic path 15, the second actuator port 142 of directional control valve 14 is connected in the second actuator port B of HM Hydraulic Motor 11 by the second hydraulic path 16, back pressure component 12 is connected in the second hydraulic path 16.
When reel 10 discharges steel rope, the power fluid force feed that need to come from Hydraulic Pump 13 flows to the first actuator port A of HM Hydraulic Motor 11 from the first actuator port 141 of directional control valve 14 through the first hydraulic path 15, complete and drive after HM Hydraulic Motor 11 actings, then through the second actuator port 142 and the return opening (unmarked) of the second hydraulic path 16, directional control valve 14, flow back to fuel tank from the second actuator port B of HM Hydraulic Motor 11.Therefore, above-mentioned the second hydraulic path 16 is a part for the oil return line of hydraulic control circuit when reel 10 discharges steel rope, and back pressure component 12 is connected in the second hydraulic path 16, thereby can realize the slow effect of the resistance of phegma force feed.
The utility model is not limited to this.For example, although as shown in Figure 1, back pressure component 12 is arranged in the hydraulic path between directional control valve 14 and HM Hydraulic Motor 11, and according to other embodiment, back pressure component 12 also can be arranged in the hydraulic path between directional control valve 14 and fuel tank.For another example, directional control valve 14 is not limited to the manual three-position four-way valve shown in Fig. 1, and can be to realize the various directional control valves that HM Hydraulic Motor 11 is driven along two contrary hand of rotation.
Therefore, when reel 10 Wound steel rope, because the liquid flowing resistance (far) of check valve 17 is for example less than back pressure element 18(, may be in off condition), therefore the power fluid force feed that comes from Hydraulic Pump 13 flows to HM Hydraulic Motor 11 through check valve 17, thereby drives reel to rotate.
When reel 10 discharges steel rope, the hydraulic oil that comes from HM Hydraulic Motor 11 can not flow through check valve 17, but flows back to fuel tank by back pressure element 18, and then produces back pressure at the upstream region of back pressure element 18, and reel 10 is hindered to slow effect.
