Description
Technical field
The present invention relates to a kind of blocking device, especially a kind of blocking device that is used for lift car and elevator rail.
Background technology
Machine-roomless lift need be provided with the blocking device of car under the situation of utilizing car top as inspection platform.At present common car blocking device adopts the lockplate that is fixed on the guide rail as load bearing component, utilizes the bolt-type securing rod that is fixed on the car frame column as the active executing parts.During locking,, thereby reach the purpose that locks lift car by the lockhole on the lockplate on the insertion of the bolt-type securing rod on the manual traversing car frame column guide rail.Blocking device is when unlock state, securing rod roof pressure electric microswitch, thereby guarantee that elevator normally moves, blocking device is when lock-out state, securing rod unclamps electric microswitch and cuts off master control circuit, ensure that like this elevator is in the halted state of maintenance, to guarantee the safety of operation of service personnel.Therefore the securing rod of car mechanical locking adopts handle to stir transverse slip, is equipped with locking and non-locking locating piece, reaches the lock in place purpose.
Because existing car blocking device is because there are the gap in locating piece and securing rod handle, thus be easy to generate impact noise, and cause poor stability; Switch on locating piece and the securing rod re-packs also gappedly in addition, and electric microswitch action is steady lost efficacy so cause easily.
Summary of the invention
The objective of the invention is provides a kind of blocking device for the poor work stability of the impact noise that solves existing car blocking device and electric microswitch, can guarantee fastness and the accuracy of securing rod in locking and unlock state position, thereby eliminate vibration noise hidden danger and guarantee the reliable in action of electric microswitch.
For achieving the above object, the invention provides a kind of blocking device, comprising:
Lockplate has lockhole on this lockplate;
Rail clip is captiveed joint with described lockplate, and described lockplate fixes by this rail clip and elevator rail;
Base, this base has securing rod sleeve and screw bolt seat;
Securing rod is slidedly arranged in the described securing rod sleeve, inserts during locking in the described lockhole;
The securing rod top board is captiveed joint with described securing rod, and is had trepanning;
Screw rod, mutually sheathed by described trepanning with described securing rod top board, and fix with described screw bolt seat.
Have inside spin in the described trepanning, have on the described screw rod be used for described trepanning in the external spiral that is spirally connected of inside spin.Be connected with the handwheel that is used to rotate on the described screw rod.Also comprise an electric microswitch, when non-locking, described securing rod top board is replaced described micro-switch.
Therefore, blocking device of the present invention, use screw stepping mechanism operation bilateral securing rod synchronization action, because screw mechanism has certain self-lock ability, can guarantee accuracy and the fastness of securing rod in locking and unlock state position, eliminate vibration noise hidden danger, also can guarantee the reliable in action of electric microswitch simultaneously.
Description of drawings
Fig. 1 is the side sectional view of blocking device of the present invention;
Fig. 2 is another structural representation of blocking device of the present invention.
The specific embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
As shown in Figure 1, be the side sectional view of blocking device of the present invention, comprise lockplate 1, have two lockholes 10 on this lockplate 1; Rail clip 2 is captiveed joint with lockplate 1, and lockplate 1 fixes by rail clip 2 and elevator rail, and lockplate 1 and rail clip 2 are formed the load bearing component of car blocking devices; Base 3, this base 3 has two securing rod sleeves 4 and screw bolt seat 5; Two securing rods 6 are slidedly arranged on respectively in two securing rod sleeves 4; Securing rod top board 7 is captiveed joint with two securing rods 6, and has 70, two securing rods of trepanning 6 and decide the operating unit that masthead plate 7 is formed the car blocking device; Screw rod 8, mutually sheathed by trepanning 70 with securing rod top board 7, and fix with screw bolt seat 5.
In addition, have inside spin in the trepanning 70, have on the screw rod 8 be used for trepanning 70 in the external spiral that is spirally connected of inside spin; Can also be connected with the handwheel 9 that is used to rotate on the screw rod 8.
When work, utilizing handwheel 9 to drive screw rod 8 rotates, inside spin rotation in the external spiral in screw rod 8 outsides and the trepanning on the securing rod top board 7 70, and screw rod 8 is fixing with the screw bolt seat 5 on the base 3, so driving securing rod top board 7 moves to the direction near lockplate 1, and with the fixing securing rod sleeve 4 of two securing rods 6 on base 3 of securing rod top board 7 in to direction slip near lockplate 1, in the time of in two lockholes 10 on the close lockplate 1, when continuing motion, in two lockholes 10 that two securing rods 6 insert on the lockplates 1, blocking device of the present invention sets firmly mutually with elevator rail.
In like manner, when reversing sense turn handwheel 9, drive screw rod 8 counter-rotation, inside spin opposite spin in the external spiral in screw rod 8 outsides and the trepanning on the securing rod top board 7 70, and screw rod 8 is fixing with the screw bolt seat 5 on the base 3, move to the direction away from lockplate 1 so drive securing rod top board 7, when being inserted in two securing rods 6 in two lockholes 10 on the lockplate 1 and leaving two lockholes 10, blocking device of the present invention and elevator rail are separated.
As shown in Figure 2, another structural representation for blocking device of the present invention, the present invention can also comprise an electric microswitch 100, when locking, securing rod top board 7 leaves electric microswitch 100, electric microswitch output electric signal is given apparatus for controlling elevator, cuts off elevator operation power loop, and the guarantee elevator is in and stops inspecting state; And when normal unlock state, securing rod top board 7 is replaced electric microswitch 100, and elevator operation power loop normal operation ensures that elevator is in normal working.
Therefore, blocking device of the present invention, use screw stepping mechanism operation bilateral securing rod synchronization action, because screw mechanism has certain self-lock ability, can guarantee accuracy and the fastness of securing rod in locking and unlock state position, eliminate vibration noise hidden danger, also can guarantee the reliable in action of electric microswitch simultaneously.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
