Description
Technical field
The utility model is related to staircase technical fields, and in particular to a kind of staircase and girder intermediate strutting device.
Background technology
Staircase and girder (including moving staircase girders and moving sidewalk truss) is large-scale steel construction piece, particularly length
Direction is longer, if middle part not supports after splicing, have in the middle part of truss it is different degrees of sagging, before step rail is installed
It needs to carry out truss straightness support correction, the left and right chord member level of truss tilting section is also required to by midfoot support device tune
It is whole.
Currently used intermediate strutting device needs two people to coordinate progress height adjusting, it is impossible to realize the quick liter of height
Drop, height is adjusted discontinuously, and height adjustment range is small, and the head design contacted with truss is unreasonable, is easily destroyed truss table
The paint in face can drive entire support device to rotate when serious, not only influencing calibration result, there is also security risks.
Utility model content
Staircase and girder intermediate strutting device provided by the utility model, simple in structure, easy to operate, lift adjustment range
Greatly, securely and reliably.
A kind of staircase and girder intermediate strutting device, including rack, further includes：
The jacking sleeve being slidably mounted in the rack, the outer wall of the jacking sleeve are equipped with rack；
The drive gear for being rotatably installed in the rack and being engaged with rack；
With the lifting handle of drive gear linkage；
Studdle of the thread fitting in jacking sleeve；
Positioned at the Universal-head of the studdle apical support staircase and girder.
In use, drive gear is driven to rotate by rotating lifting handle, the rack drives liter being meshed with drive gear
Dropping sleeve, mobile realize lifts in the vertical direction.

Bar makes the Universal-head on lifting screw top against staircase and girder.
The rotation of the lifting handle can realize the fast lifting of jacking sleeve, be adopted when carrying out the adjustment of large scale height
With the rotation of the studdle can realize the fine tuning of universal grease head highness.
Coordinated between the studdle and jacking sleeve using trapezoidal thread, stable drive is realized, in Universal-head stress
Under state, the height of Universal-head can also be adjusted by rotating studdle.
By adjusting the screw pitch of trapezoidal thread, the speed of Universal-head lifting when can control the studdle to rotate, to realize
Accurate height is adjusted.
Preferably, the rack is equipped with two support plates positioned opposite, the drive gear is installed by gear shaft
Between two support plates, one end of gear shaft is extended corresponding side support plate and is fixedly connected with the lifting handle.
Two support plates are detachably connected in rack, and the drive gear and lifting handle are mounted in two support plates,
The fast quick-detach of the components such as drive gear and lifting handle can be realized by dismantling support plate.
It can be fixedly connected between the lifting handle and gear shaft, it is preferable that between the gear shaft and lifting handle
It is matched by trapezoidal thread.
The lifting handle is eccentric single armed handle, and when not applying external force, lifting handle is in and naturally droops state, from
The lifting handle of right hang has static inertia torque.When jacking sleeve glides under self gravitation effect, drive
Moving gear and its gear shaft accordingly rotate, when the resistance that trapezoidal thread generates between lifting handle and gear shaft is less than lifting handle
Static inertia torque when, lifting handle does not rotate, but is moved to along gear shaft and leans with support plate, passes through lifting
Handle and support plate against preventing the downslide of jacking sleeve.

Under state, it can also keep height and position constant.
Preferably, the safety pin has the lock-out state for being inserted into pin hole and the release the lock state for being detached from pin hole, it is described
Lifting handle is equipped with the key seat for housing the safety pin, is set on key seat there are two card slot, the safety pin is equipped with safety pin
Bolt, safety pin are in safe pin during different conditions and are placed in corresponding card slot.
Be located in different card slots by handover security pin, can realize safety pin lock-out state and release the lock state it
Between change.
When needing to change the position of jacking sleeve, safety pin is in the release the lock state for being detached from pin hole；Need locking lifting set
During the position of cylinder, safety pin is in the lock-out state for being inserted into pin hole.After the position locking of jacking sleeve, it can only be supported by rotating
Screw rod changes the height of Universal-head.
The safety pin, key seat, safe pin are arranged on lifting handle, are increased lifting handle and are naturally drooped state
When static inertia torque, improve the self-locking property of lifting handle.
Preferably, the spring that safety pin is driven to enter lock-out state is equipped between the safety pin and key seat.In spring
Elastic force effect under, safety pin is kept to be in the lock-out state that is plugged with pin hole.
For the ease of exerting a force with the rotation for realizing studdle, it is preferable that be fixed with driving support on the studdle
The regulation handle of screw rod OQ t sleeve rotating.
Preferably, the Universal-head includes the bulb for being fixed on studdle top and activity is wrapped in outside bulb
Supporting plate, be staircase and girder supporting surface at the top of supporting plate, sliding slot of the supporting plate bottom with package bulb.
The sliding slot package bulb of supporting plate bottom, the rotary resistance of bulb are much smaller than supporting plate top staircase and girder supporting surface with helping
The resistance generated between terraced truss, during rotational support screw rod, supporting plate remains stationary as, and the relative motion for passing through sliding slot and bulb adapts to
The rotation of studdle.
Staircase and girder supporting surface at the top of supporting plate can be rotated to the angle arbitrarily needed, to ensure to connect with staircase and girder
The matching of contact portion position, ensures the stability of support, and increases forced area, prevents from scraping staircase and girder surface.
Preferably, the notch position of the sliding slot is equipped with the retainer for being in contact and being limited in bulb in sliding slot with bulb.
Bulb is limited in sliding slot by retainer, dismounting retainer can make supporting plate be detached from bulb, be convenient for changing.
The retainer uses the material with certain elasticity, can realize the effect being limited in bulb in sliding slot, simultaneously
Ensure that bulb rotation is flexible.
The quick adjustment of height can be realized in staircase and girder intermediate strutting device provided by the utility model, one man operation,
And under stress height accurate adjustment, realize the quick adjustment to staircase chord member straightness and levelness, it is time saving and energy saving,
Securely and reliably, the efficiency of assembling of staircase is improved.
