Current municipal guardrail generally comprise two hard shoulders, the column being fixed on hard shoulder, two in interval
Be arranged in parallel and be fixedly connected the cross bar of two columns, more it is being fixed between two cross bars and in vertical bar.
When carrying municipal guardrail, generally requires two people and lift municipal guardrail, then moved.Due to municipal guardrail it is whole compared with
Weight, staff can be spaced rest several times in the handling process, so that handling efficiency is lower.
Utility model content
The purpose of the utility model is to provide a kind of municipal guardrails, pass through the lifting of driving mechanisms control universal wheel
When needing mobile guardrail using universal wheel, so that movement is more convenient, and can be operated with a people, it is more convenient, carry effect
Rate is higher.
The foregoing invention purpose of the utility model has the technical scheme that
A kind of municipal administration guardrail, including hard shoulder, the hard shoulder bottom surface offer accommodating chamber, are provided in the accommodating chamber
Bracket, vertically sliding is provided with elevating lever on the bracket, and the elevating lever is connected with universal wheel, and the hard shoulder is also set up
There is the driving mechanism connecting with the elevating lever.
Elevating lever is slid downwards by driving mechanism when needing mobile guardrail by using above-mentioned technical proposal, ten thousand
To wheel and elevating lever synchronize move downward, be projected into accommodating chamber up to universal wheel, then i.e. movable guardrail；It, can when having carried
Universal wheel is retracted in accommodating chamber by driving assembly again.By the lifting of driving mechanisms control universal wheel, can need to move
Universal wheel is utilized when dynamic guardrail, so that movement is more convenient, and can be operated with a people, more convenient, handling efficiency is higher.
Preferably, the elevating lever lower end is provided with fixed plate, and the universal wheel is mounted on fixed plate side downward,
And the universal wheel is arranged at intervals with two, and straight line where the line of two universal wheels and cross bar is axially vertical.
By using above-mentioned technical proposal, guardrail can be made to help always when mobile by universal wheel without staff,
It can not be toppled over by the setting realization of two universal wheels, can further save the physical strength that staff spends when carrying.
Preferably, the universal wheel is arranged with shock-absorbing sleeve.
By using above-mentioned technical proposal, the shake and noise that guardrail occurs in the handling process are reduced, when so that carrying
It is relatively stable and quiet, the influence shaken to guard bar structure can also be reduced.
Preferably, the driving mechanism includes the rack gear being mounted on the elevating lever, is rotatably installed in the accommodating chamber
Bull stick on inner wall, the linkage gear for being mounted on the bull stick and being engaged with the rack gear, be mounted on the hard shoulder and
The Power Component being connect with the bull stick.
By using above-mentioned technical proposal, when needing to go up and down elevating lever, Power Component drives bar rotation, and rotation passes through
Linkage gear drives rack movement, and elevating lever is moved synchronously with rack gear, to realize the lifting of elevating lever.
Preferably, the Power Component includes the connection gear being mounted on the bull stick, is rotatably installed in the receiving
On the inner wall of chamber and stretch out outside the hard shoulder drive rod, be mounted on the drive rod in the accommodating chamber and with
The helical gear of the connection gear engagement.
By using above-mentioned technical proposal, rotation of drive rod, drive rod drives helical gear rotation, and helical gear rotates band
Dynamic connection gear rotation, bull stick and connection gear rotate synchronously, so that the lifting of elevating lever can be realized；Helical gear has self-locking
Function can avoid the counter motion of elevating lever after lifter rod lifting.
Preferably, the driving boom end outside the hard shoulder is connected with operating stick, the axial direction of the operating stick
It is axially vertical with the drive rod.
By using above-mentioned technical proposal, the arm of force is smaller when rotation of drive rod direct due to staff, rotation of drive rod
It is more laborious.By the setting of operating stick, arm of force when rotation of drive rod is increased, to reduce required for rotation of drive rod
Power.
Preferably, the outer wall of the hard shoulder offers subsider, and the operating stick is in the subsider.
By using above-mentioned technical proposal, if outside the prominent hard shoulder of operating stick, it is likely that since external impact is broken off, lead
Operating stick is caused to be destroyed.By the setting of subsider, so that operating stick does not protrude the outer surface of hard shoulder, so as to substantially reduce
The probability that operating stick is destroyed, improves service life.
Preferably, the inner wall of the accommodating chamber is provided with the rubber block pushed against with the drive rod, the drive rod and institute
The side wall for stating rubber block abutting has circumferentially been uniformly arranged raised band.
By using above-mentioned technical proposal, since guardrail may be shaken when carrying due to the out-of-flatness on ground,
Therefore drive rod might have slight rotation, to influence the stability of elevating lever, influence the stability of universal wheel, universal wheel
It may be retracted into accommodating chamber.By the setting of rubber block and raised band, increases the abutting power to drive rod, driving can be reduced
A possibility that bar rotates in the handling process.
In conclusion the advantageous effects of the utility model are as follows:
It 1, can be when needing mobile guardrail using universal wheel, so that moving by the lifting of driving mechanisms control universal wheel
It moves more convenient, and can be operated with people, more convenient, handling efficiency is higher；
2, by the setting of rubber block and raised band, increase the abutting power to drive rod, drive rod can be reduced and carried
A possibility that rotating in journey.
