The anterior-posterior translation in the hollowing slot 30, so as to make annulus anti-friction piece 33 be bonded and be detached from the bar 12 that connects.
When original state, under the action of ejection spring element 22, the sliding plate 21 by ejection in upper position, by
It is fixedly connected in the vertical arm 23 with the sliding plate 21, therefore, the vertical arm 23 is also in upper position, in institute
Under the action of stating the first ejection spring element 32, the sliding frame 3 is biased to forward position, due to the flat arm 31 with it is described
Sliding frame 3 is fixedly connected, and therefore, the flat arm 31 is also at preceding position, and at this point, the vertical arm 23 is not described
Flat arm 31 is squeezed, therefore the annulus anti-friction piece 33 is tightly bonded with the bar 12 that connects.
It, can be by the cunning when related personnel station is in the accommodating chamber 20 of the riser station 2 when bridge being needed to be safeguarded
Fishplate bar 21 is stepped on, and moving down for the sliding plate 21 will drive the vertical arm 23 and move down, the vertical arm 23 it is downward
Movement can make the extrusion slope 231 act on it is described be stressed slope 311 and the flat arm 31 pushed to slip backward, and it is described
Flat arm 31 can drive the sliding frame 3 to slip backward, so that the annulus anti-friction piece 33 can be made to connect the disengaging of bar 12 with described, permit
Perhaps the described riser station 2 is gone up and down, at this point, shaking the pivoting handle 421, the pivot rods 42 can be made pivoted, and
The cooperation of the upper transmitting rack gear 51 and the upper master gear 51 and gear 5 and the lower transmitting rack gear 52 and the lower master
The cooperation of gear 52 and lower gear 50, the pivot rods 42 can drive the spiral lamination upper shield 41 to pivot, and due to the spiral
Bar 4 be it is fixed, the spiral lamination upper shield 41 can be pivoted relative to each other with the screw rod 4 as a result, described so as to make
Riser station 2 rises to desired height, so as to be safeguarded, safeguarded to bridge, and described in reversely pivoting after safeguarding, safeguarding
Pivoting handle 421 can make the slow downlink of riser station.
Since left and right be accordingly arranged two connects bar and two screw rods connected between bar are arranged in, can make to connect
Hole and the friction force equalization between bar is connected, so as to go up and down riser station steadily；And connect and be set on riser station lower end,
It connects and is also fixedly installed with three side plates between set front end and the riser station bottom end, three side plates can increase the stabilization of the riser station
Property；In the initial state, annulus anti-friction piece with connect bar and be tightly bonded, therefore the riser station can be reduced when riser station is static
Due to the influence that the factor of self weight generates the spiral lamination of the screw rod and the spiral lamination upper shield, thus effective protection
The spiral lamination of screw rod and the spiral lamination upper shield；Annulus anti-friction piece is set as arc shape, it is possible to increase with the contact surface for connecting bar
Product, so as to increase frictional force；Due to the self-locking function of spiral lamination, can keep stablizing when riser station is elevated to some height,
To convenient maintenance and maintenance to bridge；Height, a side is adjusted to riser station using pivoting handle in apparatus of the present invention
Face can avoid the dependence to electric power, avoid on the other hand the lifting of riser station also being facilitated and being increased in unexpected power-off
Platform is adjusted to required height, and automatic control is strong；During riser station lifting, staff can stand in accommodating chamber, because
This greatly reduces security risk, moreover, the tool implement of maintenance needed for staff or maintenance is also disposed in accommodating chamber
In carried, therefore, also greatly facilitate the carrying of tool implement.
The above, the specific embodiment only invented, but invent protection scope be not limited thereto, it is any without
The change or replacement that creative work is expected are crossed, should all be covered within the protection scope of invention.Therefore, the protection scope of invention
It should be determined by the scope of protection defined in the claims.
