Specific embodiment
Below with reference to embodiment, the utility model is described in further detail.
When specific implementation: as shown in Figure 1, a kind of hoistway operation platform is aided with existing hoistway operation for ease of understanding
The structure of platform, as shown in Fig. 2, including laterally setting and the whole top frame 1 in rectangle, the side of the top frame 1 is fixedly mounted
There is vertically arranged support frame 2, bracing element 3, the lower end of the bracing element 3 are fixedly installed between the top frame 1 and support frame 2
It is connected to the lower end of the support frame 2, upper end is connected to the side that the top frame 1 deviates from the support frame 2；The support frame 2
Have close to the position of bottom and is additionally provided with along the vertically disposed bracket 4 in direction for deviating from the bracing element 3, the top frame 1
Lifting lug for lifting；Angle between the top frame 1 and the support frame 2 is greater than 90 °, makes the bracket 4 and the diagonal brace
When the upper end of part 3 is supported in elevator, height of the top frame 1 close to support frame side is consistently lower than the height of the other side；
The top frame 1 is hinged with the whole operation platform 5 in rectangle away from a upper side of the support frame 2, and the operation platform 5 is remote
From being provided with height adjustment mechanism 6 between the position of hinged shaft and the top frame 1.
Using the above structure, in use, making by the corbels support on support frame on the flooring of next layer of elevator door
The junction of bracing element and top frame is resisted against on the shear wall in elevator, by the weight of operating platform itself, is stuck in elevator
In well.Height due to top frame close to support frame side is consistently lower than the height of the other side, and operation platform be hinged on top frame compared with
High side, in this manner it is possible to using the height adjustment mechanism between operation platform and top frame, so as to by operation platform tune
It is whole to arrive horizontality, more stable construction plane is provided for construction personnel, is conducive to worker's construction and improves working security.
In addition, since the angle between top frame and support frame is greater than 90 °, and height of the top frame close to support frame side is consistently lower than another
The height of side, so that top frame is absolutely less than the planar dimension of elevator in the projection size of support frame short transverse.In this way, right
When operating platform is lifted by crane, there is enough gaps between operating platform and elevator, electricity can be scraped to avoid operating platform
The inner wall of stair shaft.
When implementation, the top frame 1 has the flexible jack unit 7 being vertically arranged outward close to the side of the support frame,
The telescopic end of the flexible jack unit 7 has vertically arranged backing plate 8.
In use, stretching that can be outside by the telescopic end of flexible jack unit, makes backing plate be connected to the terraced door of elevator
It on side, is stuck in the bracket of operating platform and supporting element upper end reliablely and stablely in elevator, is conducive to improve operating platform
Stability and safety in utilization.
When implementation, the flexible jack unit 7 is the hydraulic cylinder for being connected with hydraulic system, 8 thickness direction of backing plate
Side be hinged on by flexural pivot on the piston rod of the hydraulic cylinder.
Biggish pressure on top surface is capable of providing using hydraulic cylinder, it is ensured that operating platform is securely captured in elevator.
And backing plate is hinged on the piston rod of hydraulic cylinder using flexural pivot, it is ensured that when hydraulic cylinder squeezes, backing plate pastes always
On the inner wall of elevator, prevent elevator inner wall from being destroyed.
When implementation, the flexible jack unit 7 is mounted on the bottom of the top frame 1, and along perpendicular to the support frame 2
Direction setting.
In this way, when the telescopic end of flexible jack unit is stretched out on the inner wall for pressing against elevator, stretch jack unit by
Along the reaction force of the effect of direction obliquely downward, in this manner it is ensured that operating platform is securely captured in elevator.
When implementation, the height adjustment mechanism 6 includes the linear expansion mechanism 61 being mounted in the top frame 1 and entirety is in
The wedge assemblies 62 of triangle, the wedge assemblies 62 are mounted on the telescopic end of linear expansion mechanism 61, and direction
The hinged side of the operation platform 5 and top frame 1, when stretching out the telescopic end of the linear expansion mechanism 61, the wedge assemblies
62 towards the operation platform 5 and top frame 1 hinged Slideslip, and turn the operation platform 5 top frame 1 relatively upwards
It is dynamic.
When being stuck in elevator due to operating platform, the tilt angle of operation platform relative level is usually smaller, uses
Above structure squeezes the cotter mechanism between operation platform and top frame using linear expansion mechanism, can be by linear expansion mechanism
Larger stroke reduce the smaller Uplifting amount that is converted into wedge assemblies moving process, be easy to implement operation platform is gone up and down it is high
The accurate control of degree.
When implementation, the linear expansion mechanism 61 includes driving motor and the output for being coaxially mounted to the driving motor
Screw rod on axis；There is the threaded hole to match with the screw rod, the screw rod passes through and cooperates on the wedge assemblies 62
On the threaded hole of the wedge assemblies 62, when rotating the driving motor, the wedge assemblies is driven to move along screw rod.
It is mobile using feed screw nut pair driving wedge assemblies in above structure, due to feed screw nut pair have it is good from
Lock ability can stop the control to driving motor, be applied using adjutant feed screw nut after operation platform is adjusted to horizontality
For work platform locking in horizontality, structure is more reliable and more stable, improves safety in utilization.
When implementation, the wedge assemblies 62 include the lower wedge block being slideably attached in the top frame 1, and are slideably pasted
Upper voussoir on the operation platform 5, the upper voussoir is hinged on the lower wedge block by hinged shaft, and the hinged shaft is parallel
In the hinged side of the operation platform 5 and top frame 1；The threaded hole is arranged on the lower wedge block.
In this way, since upper voussoir and lower wedge block are hinged, so that wedge assemblies are in moving process, the upper table of upper voussoir
Face can be bonded operation platform always, and the lower surface of lower wedge block can be bonded top frame always, so as to reduce cotter mechanism,
The abrasion of top frame and operation platform, is conducive to extend service life.
When implementation, the wedge assemblies 62 further include being mounted under the upper surface and the operation platform 5 of the top frame 1
Guide rail on surface, the guide rail are arranged along the length direction of the screw rod；On the upper voussoir and lower wedge block have with it is described
The guide groove that guide rail matches, the upper voussoir described are led by what guide groove was slidably fit on the operation platform 5
On rail, the lower wedge block is slidably fit on the guide rail in the top frame 1 by guide groove.
In this way, both can control the direction of voussoir and lower wedge block movement by guide rail, guide rail and guiding can also be utilized
Good lubrication between slot improves the smoothness of adjusting.
When implementation, the angle between the top frame 1 and the support frame 2 is 95 ° ~ 115 °.
When implementation, the support frame 2 includes two vertically arranged support rods, and is connected laterally at two supports
Cross bar between bar；The width of two support rods is less than the width of elevator door, vertical peace on each support rod
Equipped with a bracket 4, the bracket 4 to the distance of the support rod bottom and the length of the bracket 4 is 300~
400mm；The bracing element 3 includes two hounds being separately mounted on two support rods, one end of the hound
It is fixedly connected on the lower end of the support rod, the other end is fixedly connected on the side that the top frame 1 deviates from the support frame 2；Institute
