Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1:

referring to fig. 1 and fig. 3, the present invention provides a technical solution: the utility model provides an elevator cab overhauls safety arrangement, including left stand 1 and right stand 2, left side stand 1 and right stand 2 are bilateral symmetry and set up, the top of left side stand 1 and right stand 2 all is provided with warning light 3, the warning light that sends through two sets of warning lights 3 when night and light are darker reminds people to keep away from the elevator being overhauld, thereby avoid people to go into elevator cab maintenance region by mistake, the bottom of left side stand 1 and right stand 2 all is provided with base 9, the equal fixedly connected with universal wheel 10 in four corners department of every group base 9 bottom, be provided with telescopic machanism between left side stand 1 and the right stand 2, the opposite face of left side stand 1 and right stand 2 all vertically is provided with vertical chute 8.

Telescopic machanism includes two sets of rotation bars 4, and rotate through round pin axle one rotation connection between two sets of rotation bars 4, the top of rotating bar 4 rotates through pivot one and is connected with mount 5, the bottom of rotating bar 4 rotates through pivot two and is connected with down mount 6, be provided with movable mechanism 7 on the mount 6 down, the back of the body end of carrying on two sets of mount 5 respectively with left stand 1 and 2 fixed connection of right stand, move towards opposite direction through pulling left stand 1 and right stand 2, when left stand 1 and right stand 2 move towards opposite direction separately, two sets of rotation bars 4 are driven to take place to rotate, again by two sets of rotation bars 4 and the operation of safety protection to the scene of right stand 2.

The movable mechanism 7 comprises a connecting plate 11, the two groups of lower fixing frames 6 are respectively and fixedly connected with the respective matched connecting plates 11, a sliding block 12 matched with the longitudinal sliding groove 8 is fixedly connected onto the connecting plate 11, and a guide sliding strip 13 is fixedly connected to the front end face and the rear end face of the sliding block 12. The two groups of sliding blocks 12 are respectively and movably arranged in the inner cavities of the longitudinal sliding grooves 8 which are respectively matched, the front end surface and the rear end surface of the inner cavity of each longitudinal sliding groove 8 are respectively and longitudinally provided with a limiting slide way matched with the guide slide strips 13, and each group of guide slide strips 13 are respectively and movably arranged in the inner cavities of the limiting slide ways which are respectively matched. The movement of the guide sliding strip 13 is limited through the limiting slide way, so that the sliding block 12 cannot be separated from the inner cavity of the longitudinal sliding groove 8, and the sliding block 12 can stably and smoothly move in the longitudinal sliding groove 8.

The working principle is as follows:

when the elevator maintenance platform is used, an operator needs to pull the left upright post 1 and the right upright post 2 to move towards opposite directions, when the left upright post 1 and the right upright post 2 respectively move towards opposite directions, the two groups of rotating barrier rods 4 are driven to rotate, and then the two groups of rotating barrier rods 4 and the right upright post 2 are used for carrying out on-site safety protection operation to prevent people from entering an elevator which is being overhauled. The warning light that sends through two sets of warning lights 3 when night and light are darker reminds people to keep away from the elevator that is being overhauld to avoid people to miss the elevator cab maintenance area.

Example 2:

fixedly connected with side joint strip 15 on the lateral wall of base 9, one side that base 9 was kept away from to side joint strip 15 evenly is connected with multiunit swivel nut 16, and the equal activity of inner chamber of every swivel nut 16 is pegged graft and is had adjusting screw 17, and adjusting screw 17's bottom cup joints and is fixed with bearing 18, bearing 18's bottom fixedly connected with supporting seat 19, adjusting screw 17's top fixedly connected with carousel 20.
