It states in cage comprising matrix, regulating part and locking member, the regulating part is movable to be arranged in the matrix and towards close
The direction of the rack gear extends, and the locking member is sheathed on one end end of the regulating part close to the rack gear, the locking
Part can be pierced by the cage side wall and be engaged on the rack gear.
Preferably, the locking member includes the link block for being sheathed on the regulating part end, on the link block
Tooth block with multiple sawtooth, the locking member are meshed by the sawtooth with the rack gear.
Preferably, the matrix is suspended in the cage.
Preferably, the regulating part is bolt, and the bolt thread is connected on the matrix.
Preferably, the rack gear locking device further includes the power switch in the cage, the power switch position
Below the locking member, when the locking member is towards close to the movement of the direction of the rack gear, the locking member forward direction is stirred
The power switch, the power switch disconnect；When the locking member is mobile away from the direction of the rack gear, the lock
Tight part reversely stirs the power switch, the power switch closure.
Preferably, the opening for locking piece disengaging is offered on the cage side wall.
It is further preferred that the rack gear locking device further includes the baffle being removably embedded in the opening.
Due to the application of the above technical scheme, compared with the prior art, the invention has the following advantages: one kind of the invention
For the rack gear locking device of building hoist, pass through the setting of locking member, when equipment downtime needs high-altitude maintenance, locking member
It can be good at for cage being fixed on standard knot, prevent motor internal contracting brake in maintenance process from occurring abnormal and equipment is caused to glide,
It is highly-safe.
Detailed description of the invention
Accompanying drawing 1 is the structural representation of the present invention.
Wherein: 1, matrix；2, regulating part；3, locking member；31, link block；32, tooth block；321, sawtooth；4, power switch；
100, rack gear；101, cage.
Specific embodiment
The technical solution of the present invention will be further described below with reference to the accompanying drawings.
Shown in Figure 1, a kind of rack gear locking device for building hoist, building hoist includes rack (in figure
Be not shown), along the vertical direction be set to rack on rack gear 100, by rack gear 100 go up and down be set to rack on cage 101, tooth
Locking device is located in cage 101 comprising matrix 1, regulating part 2 and locking member 3, regulating part 3 is movable to be arranged in matrix 1
In and extend towards the direction close to rack gear 100, locking member 3 is sheathed on one end end of the regulating part 2 close to rack gear 100, locks
Part 3 can be pierced by 101 side wall of cage and be engaged on rack gear 100.Here, matrix 1 is suspended in cage 101.
By the setting of locking member 3, when equipment downtime needs high-altitude maintenance, locking member 3 can be good at cage 101
It is fixed on the standard knot of rack, prevents motor internal contracting brake in maintenance process from occurring abnormal and equipment is caused to glide, it is highly-safe.
In the present embodiment, locking member 3 includes being sheathed on the link block 31 of 2 end of regulating part, on link block 31
Tooth block 32 with multiple sawtooth 321, locking member 3 are meshed by sawtooth 321 with rack gear 100.Herein, pass through sawtooth 321
It is meshed with rack gear 100, reaches fixed cage 101, the effect for preventing cage 101 from dropping.
Herein, regulating part 2 is bolt, and bolt thread is connected on matrix 1.When the rotation of bolt positive direction, bolt band
Towards close to the movement of the direction of rack gear 100, locking member 3 can be pierced by 101 wall of cage and be engaged on rack gear 100 dynamic locking member 3；
When the rotation of bolt opposite direction, bolt drives locking member 3 mobile away from the direction of rack gear 100, and locking member 3 is detached from rack gear
100。
The rack gear locking device further includes the power switch 4 in cage 101, and power switch 4 is located under locking member 3
Side, when locking member 3 is towards close to the movement of the direction of rack gear 100,3 forward direction of locking member stirs power switch 4, and power switch 4 is disconnected
It opens；When locking member 3 is mobile away from the direction of rack gear 100, locking member 3 reversely stirs power switch 4, and power switch 4 closes
It closes.
When equipment high-altitude shut down need to overhaul when, if equipment still operates in maintenance process, great peace will be present
Full hidden danger, therefore herein, by the way that power switch 4 is arranged, locked in locking member 3 towards the direction movement of close rack gear 100
When rack gear 100, power switch 4 is disconnected, otherwise power switch 4 is closed, which has thoroughly prevented security risk.
In the present embodiment, offered on 100 side wall of cage for locking piece 3 pass in and out opening (not shown), can
The baffle (not shown) of disassembly being embedded in opening.By the setting of baffle, when equipment operates normally, baffle will be locked
Tight part 3 and rack gear 100 separate, it is therefore prevented that the bolt looseness in equipment normal course of operation and cause 3 false-lock rack gear of locking member
100 the case where, occurs, and has prevented security risk.
The course of work of lower the present embodiment is illustrated in detail below: when needing to lock rack gear 100, rotating forward bolt,
Locking member 3 is mobile towards rack gear 100, and the sawtooth 321 on tooth block 32 is engaged with rack gear 100, reaches the mesh for fixing cage 101
's；When being not required to locking, bolt is rotated backward, locking member 3 retracts cage 101.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
