Example 1

Referring to fig. 1, 2 and 3, the municipal engineering foundation pit safety protection device in the illustration comprises a support base 1, and further comprises a fixed mounting column 3 welded on the top surface of the support base 1, a mounting groove 9 is formed in the fixed mounting column 3, a pull rod A10 is movably connected to the top in the mounting groove 9, a positive screw 11 is fixedly connected to a bottom port of the pull rod A10, a basket bolt 12 is connected to the positive screw 11 in a threaded manner away from the bottom port of the pull rod A10, and a reverse screw bolt fixedly connected to a pull rod B14 is connected to the bottom port of the basket bolt 12 in a threaded manner.

It should be noted that: in this scheme, after removing supporting base 1 and fixed mounting post 3 to the top edge of municipal works foundation ditch, when needs to assemble foundation ditch safety device, outwards roll out through the movable structure with mounting groove 9 inner wall with the pull rod A10 of design, make and produce the contained angle between pull rod A10 and the fixed mounting post 3, then pull rod B14, make it can not rotate, then rotate basket bolt 12, just so can make positive silk screw rod 11 and anti-silk screw rod 13 produce relative displacement on basket bolt 12 through the helicitic texture with basket bolt 12 respectively, when rotating basket bolt 12 makes positive silk screw rod 11 and anti-silk screw rod 13 when keeping away from each other, just can pull rod A10 be kept away from to pull rod B14, just so can make pull rod B14 extend.

Referring to fig. 1 and 2, a connection rotating shaft 15 is rotatably connected to an outer edge surface of a pull rod B14 in the illustration, a rotation fixing plate 6 is fixedly connected to a port on one side of the connection rotating shaft 15 away from the pull rod B14, a plurality of groups of equally spaced threaded rods 8 penetrate through the rotation fixing plate 6, the rotation fixing plate 6 is in threaded connection with the plurality of groups of threaded rods 8 through holes, and piling tips 7 are fixedly connected to ports on the bottom of the plurality of groups of threaded rods 8.

It should be noted that: when the turnbuckle 12 is rotated to extend the pull rod B14, the connecting rotating shaft 15 keeps the rotary fixing plate 6 in a horizontal state through a movable structure with the pull rod B14 until the pull rod B14 is extended to enable the piling tip 7 to be in contact with the ground, the turnbuckle 12 stops rotating, then the threaded rod 8 is rotated through a spanner at the moment, and the threaded rod 8 is rotated towards the bottom of the rotary fixing plate 6 through a threaded structure with the rotary fixing plate 6, so that the turnbuckle can be screwed into the tamped soil at the top edge of the foundation pit through the piling tip 7;

notably, are: after the threaded rod 8 is rotated to the top surface and the top surface of the rotary fixing plate 6 are flush, the threaded rod 8 stops rotating, most of the threaded rod 8 at the moment is drilled in the ground, the contact area between the whole protective device and the ground is increased, after the installation of the protective device is completed, the stability of the protective device is improved through the friction force between the threaded rod 8 inserted into the ground and the tension of the ground, and the safety of the municipal engineering foundation pit protective device in use can be effectively improved.

Example 2

Referring to fig. 1 and 3, this embodiment further describes example 1, in which a plurality of groups of mounting screw holes 2 are formed on the outer edge surfaces of the left and right sides of the fixing mounting column 3, and a plurality of groups of guard rails 5 for protecting the municipal engineering foundation pit are connected in the mounting screw holes 2 by threads.

It should be noted that: firstly, after a group of support bases 1 and fixed mounting columns 3 are fixedly mounted, a protective guard 5 is screwed into a mounting screw hole 2 in the fixed mounting column 3, then an adjacent group of support bases 1 and fixed mounting columns 3 are mounted, then the other end of the protective guard 5 is aligned with the mounting screw hole 2 on the fixed mounting column 3 mounted at the moment, and the protective guard is rotated in, so that one end of the protective guard 5 which is originally screwed into the mounting screw hole 2 is slightly screwed out of the mounting screw hole 2, and the other end of the protective guard 5 is screwed into the mounting screw hole 2 on the fixed mounting column 3 mounted later.

In addition, referring to fig. 1 and 3, a top rail 16 is screwed on one side of the top of the fixed mounting post 3 in the drawing, a top protection plate 4 is welded on the top rail 16, and the top protection plate 4 has a hollow structure.

It should be noted that: the top protection plate 4 arranged on the top railing 16 can prevent the problem that workers fall off by surmounting the guard rail 5 by illegal operation, and can meet the use requirement.

Notably, are: for blocking the top edge of municipal works foundation ditch through equidistant multiunit rail guard 5 of arranging, prevent that the staff from falling in the foundation ditch because unexpected and causing the injury, and the space between each rail guard 5 has reduced protector and air's contact, also can effectually prevent that protector from being scraped under the great weather of wind-force and turn over, and can demolish top railing 16 and rail guard 5 in the time of not using, remove fixed mounting post 3 and top railing 16 and rail guard 5 respectively, improved the facility when carrying rail guard 5, and the installation is comparatively convenient, can satisfy the user demand.
