Preferably, described stroke piston bar can seesaw and be arranged in described stroke piston cylinder body, and its rear end is positioned at described stroke piston cylinder body, and the extended described stroke piston cylinder body of its front end is also connected with the described line that declutches; One end of described active piston bar is movably arranged in described active piston cylinder body, and the other end stretches out described active piston cylinder body; Described stroke piston bar is also provided with piston limiting device along the rear of the direction that seesaws, and is provided with and makes the travel forward elastic component of reset of described stroke piston bar between described stroke piston cylinder body and described stroke piston bar.
More preferably, described elevator long distance brake-loosing mechanism also comprises the line inhibiting device that declutches, described in the line that declutches only can move described in being arranged on and declutch on line inhibiting device along self length direction.
In one embodiment, described in the line inhibiting device that declutches be the riser being fixedly installed on described motor, described riser be only provided with for described in the hole that line activity passes of declutching.
Preferably, described active piston bar and the vertical setting mutually of described stroke piston bar.
More preferably, described active piston bar moves along the vertical direction and is arranged in described active piston cylinder body.
Owing to adopting technique scheme, when operation active piston bar is when moving in active piston cylinder body, active piston bar promotes hydraulic medium, hydraulic medium flows in stroke piston cylinder body, according to pascal's principle, under action of hydraulic force, thereby promote stroke piston bar moves in stroke piston cylinder body, stroke piston bar pulls the line that declutches to reach the enough large power that declutches, and makes the handle motion that declutches, and produces the effect that declutches.While end when declutching, unclamp active piston bar, under the application force of elastic component, stroke piston bar can reset rapidly again, and hydraulic medium flows into active piston cylinder body from stroke piston cylinder body, and active piston bar is returned to initial position.
Compared to prior art, the utility model is simple in structure, easy to operate, can realize elevator long distance declutches, and adopt the hydraulic gear generation power that declutches to drive the handle that declutches, therefore by diameter of cylinder ratio suitable between active piston cylinder body and stroke piston cylinder body is set, the line that just can make to declutch produces the larger power that declutches in the time declutching.

In accompanying drawing: 1-retracing spring; 2-stroke piston bar; The 3-line inhibiting device that declutches; The 4-handle that declutches; 5-motor; 6-piston limiting device; 7-active piston bar; The 8-line that declutches.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Refer to Fig. 1, the utility model provides a kind of elevator long distance brake-loosing mechanism, comprising: the line 8 that declutches, handle 4 and be arranged on elevator outside in order to drive the line 8 that declutches to produce pulling force and pull the hydraulic gear of the handle 4 that declutches declutches.The handle 4 that declutches can be arranged on to side-to-side movement on motor 5.
Hydraulic gear comprises stroke piston cylinder body, be movably arranged on stroke piston bar 2, the active piston cylinder body being connected with described stroke piston cylinder body in stroke piston cylinder body, be movably arranged on the active piston bar 7 in described active piston cylinder body.Between described stroke piston cylinder body, described stroke piston bar 2, described active piston cylinder body and stroke piston bar 2, form the confined space that is full of hydraulic medium, hydraulic medium can be hydraulic oil.Described stroke piston cylinder body can be fixedly mounted on construction wall or on fixed support, stroke piston bar 2 can seesaw and be arranged in described stroke piston cylinder body, its rear end is positioned at described stroke piston cylinder body, and the extended described stroke piston cylinder body of its front end is also connected with the line 8 that declutches.One end of active piston bar 7 is movably arranged in described active piston cylinder body, and the other end stretches out described active piston cylinder body.In the present embodiment, active piston bar 7 and the mutual vertical setting of stroke piston bar 2, active piston bar 7 moves along the vertical direction and is arranged in described active piston cylinder body.
Stroke piston bar 2 is also provided with piston limiting device 6, the ultimate range that piston limiting device moves backward in order to limit stroke piston bar 2 along the rear of the direction that seesaws.Between stroke piston cylinder body and stroke piston bar 2, be provided with make stroke piston bar 2 travel forward reset retracing spring 1.
Described elevator long distance brake-loosing mechanism also comprises the line inhibiting device 3 that declutches, described in the line 8 that declutches only can move to be arranged on along self length direction and declutch on line inhibiting device 3, one end of the line 8 that declutches connects the handle 4 that declutches, the other end connects stroke piston bar 7.In the present embodiment, the line inhibiting device 3 that declutches is positioned at the left side of the handle 4 that declutches, the described line inhibiting device that declutches is the riser being vertically fixedly installed on motor 5, and described riser is provided with the hole of only passing for line 8 activities of declutching, and the height in this hole is consistent with the height of the handle upper end of declutching.The effect of line inhibiting device 3 of declutching is to fix the line 8 that declutches, and the line 8 of avoiding declutching swings, and guarantees that application of force direction is accurate, and the line 8 that makes at every turn to declutch is all to pull from right to left the handle 4 that declutches.
In the time that operation active piston bar 7 upward movements enter in active piston cylinder body, active piston bar 7 promotes hydraulic medium, hydraulic medium flows in stroke piston cylinder body, according to pascal's principle, under action of hydraulic force, promote stroke piston bar 2 and move backward along stroke piston/cylinder, the front end of stroke piston bar 2 is inwardly retracted, under the pulling of stroke piston rod 2, the line 8 that declutches produces pulling force along self length direction makes to declutch handle 4 to left movement, produces the effect that declutches.Break for fear of the handle 4 that will declutch, adopt piston limiting device 6 to limit the position of stroke piston bar 2, when the handle 4 that declutches moves to left while opening band-type brake completely, the rear end of stroke piston bar 2 is resisted against on piston limiting device 6 and cannot moves backward again.
While end when declutching, unclamp active piston bar 7, under the application force of retracing spring 1, stroke piston bar 2 resets that can travel forward rapidly again, hydraulic medium is from stroke piston cylinder body inflow active piston cylinder body, and active piston bar 7 is returned to initial position.
