Description

A kind of remote brake-releasing gear
Technical field
The utility model relates to traction machine technical field more particularly to a kind of remote brake-releasing gears.
Background technique
When band-type brake occurs for elevator power loss or failure, implement rescue to open band-type brake, usually by directly beating manually Shredding lock handle or long-range control, which are opened handle both modes of declutching and realized, declutches.But in machine-roomless lift, the hand of people Arm can not encounter the handle that declutches of motor due to being limited by space, therefore can not declutch manually.And existing some long-range pines In brake mechanism, since the power that declutches that the mechanical structure of use generates is smaller, it is unable to reach and manipulates the power that declutches needed for handle that declutches, Usually it is unable to reach the effect that declutches.Therefore, design that a kind of structure is simple, is manually operable, the biggish elevator long distance pine of the power that declutches Brake mechanism, which just seems, to be even more important.
Position-limit mechanism in existing remote brake-releasing gear cannot open the effect of guiding for core wire, by pulling core wire to make The handle that must declutch rotates so that traction machine declutches, and the case where being difficult to return to initial position often occurs in the handle that declutches after rotation, In addition, the position of resetting-mechanism is unable to adjust, enough reset forces just cannot be improved with resetting-mechanism after a period of time, in turn The handle that declutches after leading to rotation can not reset.
Summary of the invention
For the above-mentioned deficiency of the prior art, the technical problem to be solved by the utility model is to be proposed a kind of long-range Brake-releasing gear.
The utility model solves its technical problem the technical solution adopted is that a kind of remote brake-releasing gear, which is characterized in that Include:
Operation handle;
Declutch handle;Its set is on the brake;
Declutch line, including core wire and casing;Described sleeve pipe covers on the core wire;The set is stretched out at the both ends of the core wire Pipe is outer;The both ends of the core wire respectively with declutch handle and operation handle is connected;
Position-limit mechanism is arranged near the handle that declutches, and the position-limit mechanism includes fixing seat and directive wheel;It is described solid The end of reservation fixed sleeving, directive wheel is drawn from the end and bypassed to the core wire and the handle that declutches is connected;
Resetting-mechanism, including fixed plate and reset spring, one end of the reset spring and fixed plate are connected, the other end Handle is connected with declutching.
Preferably, the handle that declutches includes socket end and connecting pin, and the socket end cap is described on the brake Connecting pin and core wire are connected.
Preferably, the connecting pin is provided with location hole, and the core wire is fixed in the location hole.
Preferably, the junction of the reset spring and the handle that declutches is between socket end and connecting pin.
Preferably, the fixed plate is provided at least two fixation holes, and the fixation hole is in kidney-shaped.
The utility model setting can be the position-limit mechanism of core wire guiding, and the position-adjustable of resetting-mechanism is multiple by adjusting The reset force of the position-adjustable reset spring of position mechanism guarantees that reset spring has enough reset forces, after capable of promoting rotation The handle that declutches can reset to initial position.
Detailed description of the invention
Fig. 1 is the front view of the utility model;
Fig. 2 is the side view of the utility model.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these examples.
Fig. 1-Fig. 2 is please referred to, the utility model discloses a kind of remote brake-releasing gear, which is characterized in that including operation handle 100, declutch handle 200, declutch line 300, position-limit mechanism and resetting-mechanism;Pass through the remote controlled brake of operation handle 100 600 make traction machine declutch.
Declutch handle 200;Its set is on brake 600;Rotating the handle 200 that declutches can drive brake 600 to make traction machine It declutches.
Declutch line 300, including core wire 310 and casing 320;320 sets of described sleeve pipe on the core wire 310;The core wire 310 both ends are stretched out outside described sleeve pipe 320;The both ends of the core wire 310 respectively with 100 phase of handle 200 and operation handle that declutches Even;For described sleeve pipe 320 for protecting core wire 310 to be damaged to prevent core wire 310, described sleeve pipe 320 also acts as constraint core wire 310 With the effect being oriented to for the core wire 310.
Position-limit mechanism is arranged near the handle 200 that declutches, and the position-limit mechanism includes fixing seat 410 and directive wheel 420;The end of 410 fixed sleeving 320 of fixing seat, the core wire 310 draw from the end and bypass directive wheel 420 and institute The handle 200 that declutches is stated to be connected;In this embodiment, it is to pass through operation that by operation handle 100, remotely control traction machine, which declutches, Handle 100 pulls core wire 310, and core wire 310 drives the declutch rotation of handle 200, in the specific implementation process, the line that declutches 300 length is longer, in order to ensure declutch line 300 can stable pulling declutch handle 200 rotate, limited by position-limit mechanism The position of 320 end of casing, then guide core wire 310 to be connected again with the handle 200 that declutches by directive wheel 420, it is ensured that every time It pulls direction of pull when declutching handle 200 consistent by core wire 310, and to pass through the pulling core wire of operation handle 100 every time When 310, the handle 200 that declutches can be pulled so that traction machine is declutched in turn.
Resetting-mechanism, including fixed plate 510 and reset spring 520, one end of the reset spring 520 and fixed plate 510 It is connected, the other end and the handle 200 that declutches are connected;Pulling is declutched after the rotation of handle 200, can be resetted by resetting-mechanism;? In this embodiment, the reset spring 520 connects the fixed plate 510 and the handle 200 that declutches, and reset spring 520, which can allow, to be turned The handle 200 that declutches after dynamic automatically resets.
Preferably, the handle 200 that declutches includes socket end 210 and connecting pin 220, and 210 sets of the socket end is described On brake 600, the connecting pin 220 is connected with core wire 310.
Preferably, the connecting pin 220 is provided with location hole 221, and the core wire 310 is fixed in the location hole 221.
Preferably, the junction of the reset spring 520 and the handle 200 that declutches be located at socket end 210 and connecting pin 220 it Between;
Preferably, the fixed plate 510 is provided at least two fixation holes 511, and the fixation hole 511 is in kidney-shaped, tool Body says that the fixation of the fixed plate 510 is position-movable;In this embodiment, the fixed plate 510 is fixed on traction machine On, it is passed through by bolt and the fixed plate 510 is fixed on traction machine in the fixation hole 511 of kidney-shaped, loosered a bolt, fixed plate The generation of reset spring 520 can be changed by adjusting the position of fixed plate 510 for 510 removable certain distances, then tighten bolt Pulling force;That is, the fixation position of the fixed plate 510 is adjustable, it is adjustable multiple by adjusting the fixation position of fixed plate 510 The tensile elongation of position spring 520, and then adjust the pulling force that reset spring 520 holds the handle 200 that declutches.
