[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Embodiment one, by Figure 1 The utility model relates to a kind of supporting devices for municipal construction, including base 1, the top of base 1 is horizontally provided with support plate 3, the top of support plate 3 is fixedly connected with protective fence 4, two adjusting cylinders 5 are symmetrically fixedly installed between support plate 3 and base 1, the bottom of support plate 3 is equipped with limiting mechanism 2, when starting two adjusting cylinders 5, support plate 3 can be made to move longitudinally, to facilitate the height of support plate 3 is adjusted.

[0024] Specifically, by Figures 2-4The limiting mechanism 2 includes a crossbar 201 located between the support plate 3 and the base 1. Both ends of the crossbar 201 are fixedly connected to upright plates 207, which are fixed to the top of the base 1. The tops of both upright plates 207 are fixedly connected to outer rings 204. Two columns 203 are symmetrically fixedly connected to the bottom of the support plate 3, and each column 203 passes through one of the outer rings 204. Two nuts 205 are symmetrically and movably sleeved on the outer side of the crossbar 201. Insert rods 208 are fixedly connected to the sides of the two nuts 205 that are far apart from each other. The two insert rods 208 pass through the two upright plates 207. Multiple insertion holes 209 are evenly spaced on the outer sides of the two columns 203, and the two insert rods 208 are inserted into two corresponding insertion holes 209. A bidirectional lead screw 202 is provided below the base 1. The bidirectional lead screw 202 is rotatably connected between two vertical plates 207. Two screw nuts 205 are symmetrically threaded onto the outside of the bidirectional lead screw 202. A U-shaped round rod 2013 located below the bidirectional lead screw 202 is fixedly connected to the top of the base 1. A sliding plate 206 is movably sleeved on the outside of the U-shaped round rod 2013. A toothed plate 2015 is fixedly connected to the top of the sliding plate 206. A gear 2014 is fixedly installed in the middle of the outside of the bidirectional lead screw 202. The gear 2014 meshes with the toothed plate 2015. A bottom block 2010 is fixedly connected to the bottom of the sliding plate 206. A sleeve block 2012 is fixedly sleeved on the outside of the U-shaped round rod 2013. A drive cylinder 2011 is fixedly installed between the sleeve block 2012 and the bottom block 2010.
