Abstract
The utility model discloses a catch block lifting mechanism on an elevator. The mechanism comprises a draw bar, a casing pipe component and a limit component, wherein the casing pipe component is sleeved on the draw bar; the limit component is fixedly arranged on the draw bar and presses against the casing pipe component to prevent the casing pipe component from moving along the longitudinal direction of the draw bar; and the casing pipe component can be rotationally sleeved on the draw bar. A positioning structure used for positioning the casing pipe component is arranged between the casing pipe component and the limit component or between the casing pipe component and the draw bar, so in a lifting mechanism assembling process, if an augular offset exists between the position of the casing pipe component and the position of a limiter steel wire rope, the casing pipe component is rotated to a proper position and then is positioned through the positioning structure to smoothly connect the casing pipe component and the limiter steel wire rope. Therefore, the assembly is smoothly performed, and the working efficiency is improved.

Preferably, described locating part comprises and being separately positioned on above the described thimble assembly and following upper limit spare and lower limit part, described upper limit spare is inconsistent with the end face of described thimble assembly, the bottom surface of described lower limit part and described thimble assembly is inconsistent, and described detent mechanism is arranged between described thimble assembly and described upper limit spare or the described lower limit part.
Further preferably, described location structure comprises the jack that is opened on the described thimble assembly, is opened on the described lower limit part and is a plurality of perforates that distribute separately of the circumferencial direction at center, can inserts the latch in described jack and the described perforate simultaneously along the rotary centerline with described thimble assembly.
Still more preferably, described latch is inserted in the described jack, is provided with between described latch and the described thimble assembly to be used for providing an elastic-restoring force to make this latch stablize the elastic component that inserts described perforate.
Again still more preferably, described jack, described perforate all distribute along the longitudinal direction of described draw bar.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: thimble assembly can be set on the draw bar rotationally, thimble assembly is used for being connected with speed limiter wire rope, like this in the fitting process of shift mechanism, when if there are angular deviation in the position of generation thimble assembly and the position of speed limiter wire rope, then the rotating casing assembly is to suitable position, by location structure thimble assembly is located then, can finish being connected of thimble assembly and speed limiter wire rope so smoothly, make fitting work smooth, increase work efficiency.
Description of drawings
Accompanying drawing 1 is looked scheme drawing for master of the present utility model;
Accompanying drawing 2 is an I place enlarged drawing in the accompanying drawing 1, and wherein latch is inserted in the perforate of the jack of thimble assembly and lower limit part simultaneously;
Accompanying drawing 3 is the partial enlarged drawing that latch breaks away from the perforate of lower limit part in the utility model;
Accompanying drawing 4 is the enlarged diagram of overlooking of the present utility model, not shown steel rope and rope attaching parts.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-4, safety tongs shift mechanism on the elevator, comprise draw bar 1, can be set in the thimble assembly 4 on the draw bar 1 rotationally, be fixedly installed on the draw bar 1 and with the inconsistent locating part 5 of thimble assembly 4 to forbid that this thimble assembly 4 moves along the longitudinal direction of draw bar 1, thimble assembly 4 can be set on the draw bar 1 rotationally, thimble assembly 4 is used for being connected with speed limiter wire rope 15, like this in the fitting process of shift mechanism, when if there are angular deviation in the position of generation thimble assembly 4 and the position of speed limiter wire rope 15, then rotating casing assembly 4 is to suitable position, owing to be provided with the location structure 16 that is used to locate this thimble assembly 4 between thimble assembly 4 and locating part 5 or the draw bar 1, then thimble assembly 4 is positioned to suitable position by location structure 16, finish being connected of thimble assembly 4 and speed limiter wire rope 15 smoothly, make fitting work smooth, increase work efficiency.
The prior art that is connected to of thimble assembly 4 and speed limiter wire rope 15, in Fig. 1 and 4, thimble assembly 4 comprises sleeve pipe 12, is fixedly installed on the connecting strap 3 on the sleeve pipe 12, the two ends of speed limiter wire rope 15 all are connected the two ends of attaching parts 13 by rope attaching parts 14, connecting strap 3 on attaching parts 13 and the thimble assembly 4 is fixedly connected, when speed limiter wire rope 15 takes place along the lifting of draw bar 1 longitudinal direction like this, by the conflict of thimble assembly 4 with locating part 5, drive draw bar 1 pull lift action also takes place, the brake safe pincers.
In Fig. 1, locating part 5 comprises and is separately positioned on above the thimble assembly 4 and following upper limit spare 6 and lower limit parts 7, upper limit spare 6 is inconsistent with the end face of thimble assembly 4, lower limit part 7 is inconsistent with the bottom surface of thimble assembly 4, upper limit spare 6, lower limit part 7 all can adopt the annulus of fixed cover on draw bar 1, upper limit spare 6 is set, lower limit part 7, make thimble assembly 4 on draw bar 1, to rotate, moving of longitudinal direction can not be taken place, can realize lifting of draw bar 1 longitudinal direction by thimble assembly 4 like this, detent mechanism 16 is arranged between thimble assembly 4 and upper limit spare 6 or the lower limit part 7.
