DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 , an embodiment provided by the utility model:

[0024] A railing for a municipal pipeline construction trench: comprising a railing body 1, a Larsen steel sheet pile 11 is fixedly installed at the bottom of the railing body 1, a fence net 12 is fixedly installed at the side of the railing body 1, a clamping block 2 is fixedly connected to the bottom of the railing body 1, a movable rod 21 is slidably connected to the surface of the clamping block 2, a first connecting rod 22 is fixedly connected to the surface of the movable rod 21, a spring 23 is fixedly connected to the surface of the clamping block 2, a clamping piece 24 is fixedly connected to the surface of the movable rod 21, an end of the spring 23 away from the clamping block 2 is fixedly connected to the clamping piece 24, a first nut 25 is fixedly connected to the surface of the clamping piece 24, and the clamping block 2 is fixedly connected to the surface of the railing body 1 with a first nut 25, and the surface of the first nut 25 is threadedly connected to the first bolt 26. During the process of installing the Larsen steel sheet pile 11 on the surface of the railing body 1, there is no need to hold the Larsen steel sheet pile 11 by hand. It is only necessary to clamp the clamp block 2 on the top of the Larsen steel sheet pile 11 to continue to complete the installation of the railing body 1 on the Larsen steel sheet pile 11, and fix it with the first bolt 26. The position of the first bolt 26 is locked on the Larsen steel sheet pile 11 by the clamp block 2, so there is no need to position the first bolt 26, making the installation of the Larsen steel sheet pile 11 convenient and efficient.

[0025] Furthermore, a sliding rod 3 is slidably connected to the surface of the railing body 1, and a vertical rod 31 is fixedly connected to the surface of the sliding rod 3. The fence net 12 is fixedly connected to the surface of the vertical rod 31. A second bolt 33 is perforated and connected to the surface of the railing body 1, and a second connecting rod 32 is fixedly connected to the second bolt 33. A second nut 34 is threadedly connected to the surface of the second bolt 33. The sliding rod 3 and the vertical rod 31 allow the fence net 12 and the clamping block 2 to be disassembled, and then the sliding rod 3 can be fixedly installed on the railing body 1 through the second connecting rod 32, the second bolt 33 and the second nut 34, thereby achieving fixed installation of the fence net 12 on the railing body 1. When the fence net 12 is damaged, the fence net 12 can be replaced and maintained, and the weight of the fence net 12 is reduced during the installation of the railing body 1 to the Larsen steel sheet pile 11, making the installation more convenient.

[0026] Furthermore, a slot is provided at the bottom of the clamp block 2, and the Larsen steel sheet pile 11 is snap-connected to the slot at the bottom of the clamp block 2. The slot of the clamp block 2 limits the position of the clamp block 2 at the top of the Larsen steel sheet pile 11. There are multiple sets of inclined surfaces on the surface of the Larsen steel sheet pile 11, and the two ends of the clamp block 2 are restricted by the inclined surfaces, so that the clamp block 2 cannot slide on the top of the Larsen steel sheet pile 11 through the slot. At this time, the positions of the first nut 25 and the first bolt 26 on the clamp block 2 just correspond to the installation holes opened in the Larsen steel sheet pile 11.

[0027] Furthermore, rectangular grooves are provided on both sides of the clamping block 2 slot, and the movable rod 21 slides on the surface of the clamping block 2. The movable rod 21 drives the clamping piece 24 to move on the clamping block 2 slot and the rectangular groove, and the elastic force of the spring 23 acts on the movable rod 21 through the clamping piece 24. Two groups of movable rods 21 are fixedly connected to a group of first connecting rods 22. The movable rod 21 can slide on the clamping block 2 to the clamping block 2 slot and the rectangular groove, and the clamping pieces 24 are symmetrically distributed on the surface of the clamping block 2.

[0028] Furthermore, a plurality of groups of convex strips are provided on the surface of the clamp 24, and the convex strips are arranged linearly and uniformly. The convex strips increase the clamping force of the clamp 24 on the Larsen steel sheet pile 11, thereby ensuring that the position of the clamp block 2 will not move. A guide hole is provided on the surface of the clamp block 2, and a first nut 25 is fixedly connected to the guide hole of the clamp block 2. The first bolt 26 passes through the guide hole of the clamp block 2 through the first nut 25. The first bolt 26 can slide to the slot and the rectangular slot of the clamp block 2. The first bolt 26 passes through the installation hole of the railing body 1. The first bolt 26 limits the position of the clamp block 2 on the Larsen steel sheet pile 11, thereby fixing the railing body 1 on the top of the Larsen steel sheet pile 11.

[0029] Furthermore, trapezoidal grooves are provided on both sides of the railing body 1, and the sliding rod 3 is in a trapezoidal shape. The vertical rod 31 slides onto the surface of the railing body 1 through the sliding rod 3. The sliding rod 3 limits the position of the vertical rod 31 on the railing body 1, thereby limiting the position of the fence 12 on the railing body 1. At this time, the sliding rod 3 and the vertical rod 31 can only slide upward on the railing body 1.

[0030] Furthermore, a circular hole is opened on the surface of the railing body 1, and the circular hole of the railing body 1 is connected to the trapezoidal groove of the railing body 1. The second bolt 33 passes through the circular hole of the railing body 1, and the side of the second bolt 33 is abutted and connected to the top of the vertical rod 31. The second bolt 33 limits the position of the sliding rod 3 on the trapezoidal groove of the railing body 1, and the second nut 34 fixes the second bolt 33 to the top of the railing body 1. The second connecting rod 32 is simultaneously connected to two groups of second bolts 33, which improves the efficiency of installing the second bolts 33.

[0031] Working principle: make installation holes on the top of the Larsen steel sheet pile 11, pull the first connecting rods 22 on both sides of the clamping block 2, so that the movable rod 21 drives the clip 24 to move on the clamping block 2, so that when the clip 24 moves to the rectangular groove of the clamping block 2, the card slot at the bottom of the clamping block 2 is engaged and connected to the top of the Larsen steel sheet pile 11, and the first connecting rod 22 is released. The elastic force of the spring 23 will make the clip 24 clamp the Larsen steel sheet pile 11. With the support of the convex strip of the clip 24, the position of the clamping block 2 is limited to the top of the Larsen steel sheet pile 11, and the railing body 1 does not need to be installed by hand. Since the position of the clamping block 2 is fixed, the positions of the first nut 25 and the first bolt 26 on the Larsen steel sheet pile 11 are locked, and the first bolt 26 rotates on the first nut 25 to pass through the installation hole of the Larsen steel sheet pile 11, so that the railing body 1 is installed on the top of the Larsen steel sheet pile 11 through the clamping block 2.

[0032] The slide bar 3 is slid onto the trapezoidal groove of the railing body 1, so that the vertical rod 31 is moved to the surface of the railing body 1. At this time, the two sets of second bolts 33 are passed through the circular hole of the railing body 1 through the second connecting rod 32. The second nut 34 rotates on the second bolt 33 to fix the second bolt 33 and the second connecting rod 32 to the railing body 1. At this time, the second bolt 33 limits the position of the slide bar 3 at the top of the slide bar 3, so that the vertical rod 31 and the fence 12 are fixed on the surface of the railing body 1, which is convenient for disassembly of the fence 12 on the railing body 1 and also makes the railing body 1 not have the weight of the fence 12 during the installation process.
