The invention is described in further detail below with reference to the figures and the specific embodiments.

As shown in figures 1-7 a city utility tunnel pedestrian protection device, including the protection frame and locate the running gear of the lower extreme of protection frame, maintainer or pedestrian are in the protection frame, and maintainer promotes the synchronous motion of protection frame when walking in the piping lane, make the protection frame protect the maintainer all the time and avoid the extrusion or the pressure of piping lane interior pipeline to bury.

Specifically, the method comprises the following steps: the protective frame comprises a vertical frame 1, a cross beam 2 and a protective guard 3; two vertical frames 1 are arranged in parallel at a certain interval; each vertical frame 1 comprises a horizontal rod 1.2 and vertical rods 1.1 arranged at two ends of the horizontal rod 1.2; at least one guard rail 3 is respectively arranged on the opposite surfaces or the opposite surfaces of the two vertical frames 1; two ends of the cross beam 2 are respectively connected with the horizontal rods 1.2 of the two vertical frames 1. Referring to fig. 1 to 3, a walking interval of a maintainer is arranged between two vertical frames 1; in order to facilitate walking and maintenance operation, the distance between the two vertical frames 1 is larger than 1 meter, and certainly, the distance between the two vertical frames 1 is smaller than the width of a maintenance channel in a pipe gallery. In order to ensure the stability and rigidity of the whole structure of the protective frame, a reinforcing rod 4 is arranged between the two ends of the two vertical frames 1. The reinforcing rods 4 in this embodiment are welded to the two ends of the two vertical frames 1 in an X-shape by using flat steel. The crossbeam 2 has a plurality ofly, and a plurality of crossbeams 2 are along the horizontal pole 1.2 length direction interval setting of grudging post 1.

The guard rail 3 comprises a plurality of connected transverse railings 3.1 and vertical railings 3.2; the two ends of the transverse railing 3.1 are connected with the vertical rod 1.1 of the vertical frame 1, and the upper end of the vertical railing 3.2 is connected with the horizontal rod 1.2 of the vertical frame 1. The transverse handrail 3.1 is connected with the vertical handrail 3.2 through a connecting bolt 3.4; the transverse railing 3.1 and the vertical railing 3.2 are respectively provided with a plurality of connecting threaded holes 3.3 matched with the connecting bolts 3.4. In this embodiment, the guard rail 3 includes two transverse rails 3.1 and three vertical rails 3.2; the transverse railings 3.1 and the vertical railings 3.2 are respectively provided with a plurality of connecting threaded holes 3.3, and a maintainer can adjust the distance between the two transverse railings 3.1 or the three vertical railings 3.2 by adjusting the positions of the connecting threaded holes 3.3 matched with the connecting bolts 3.4 according to the maintenance requirement; of course, the number of the cross rails 3.1 or the vertical rails 3.2 can also be reduced, referring to fig. 5, the guard rail 3 has two rectangular access ports, and if a larger access port is needed, the connecting bolt 3.4 on the second vertical rail 3.2 from the left can be unscrewed, and the second vertical rail 3.2 is moved to the left or right for a certain distance and then is installed on the cross rail 3.1 again through the connecting bolt 3.4.

It should be noted that, in order to facilitate the size adjustment of the protection frame, the vertical rod 1.1, the horizontal rod 1.2 and the cross beam 2 of the vertical frame 1 can be telescopic rod structures, so as to adjust the size of the protection frame, and facilitate the expansion of the width of the walking interval or the adaptation of the access passage in the pipe gallery.

One or more handrails 5 are provided on the stand 1 or the guard rail 3. In the embodiment, the handrail 5 is preferably arranged on the vertical handrail 3.2, and a service person in the protective frame holds the handrail 5 to push the protective frame to move in the service passage in the pipe gallery.

The travelling mechanism in the embodiment comprises a ground rail 6, a travelling wheel 7, a guide wheel 8 and a mounting plate 9; the ground rail 6 is arranged along the length direction of the pipe gallery, and the ground rail 6 is a horizontally arranged channel steel with an upward concave surface; the lower end of the vertical rod 1.1 is provided with a walking wheel 7 and a guide wheel 8 with vertical rotating shafts; the circumferential end of the travelling wheel 7 abuts against the horizontal bottom end face of the ground rail 6, and the circumferential end of the guide wheel 8 abuts against the vertical side end face of the ground rail 6.

Referring to fig. 7, two horizontal mounting plates 9 are welded to two side ends of the ground rail 6, and a plurality of mounting holes 11 are formed in the mounting plates 9 along the length direction thereof. The upper end of the mounting plate 9 is at the same level as the upper end of the ground rail 6. When the ground rail 6 is installed, the position of the ground rail 6 to be set is set according to the width of the maintenance channel in the pipe gallery and the distance between the two vertical frames 1, after the position of the ground rail 6 is determined, the pipe gallery ground at the position of the ground rail 6 to be set is grooved, the depth of the grooved opening is more than or equal to the height of the ground rail 6, and the width of the grooved opening is more than or equal to the width of the ground rail 6 but less than the distance between the two installation plates 9. Thereby make ground rail 6 can the level place in the notch that pipe gallery ground opened out to guarantee that ground rail 6 is in the level, in order to make 6 installations of ground rail stable, still can fill cement mortar between the notch on ground rail 6 and pipe gallery ground. Further fix mounting panel 9 in the both sides of the notch that the piping lane ground opened out through mounting bolt 10 with mounting hole 11 complex, still can establish the levelness of gasket adjustment ground rail 6 through the cover on mounting bolt 10.

Referring to fig. 6, two opposite axial ends of the travelling wheels 7 of the lower end of the vertical rod 1.1 are respectively provided with a guide wheel 8. Because the ground rail 6 of this embodiment is the channel-section steel, and leading wheel 8 and walking wheel 7 all are in the recess of channel-section steel, and leading wheel 8's effect makes the lower extreme of erecting pole 1.1 be in the position placed in the middle in the channel-section steel all the time, makes manual promotion protective frame remove more laborsaving. For more labor saving, the road wheels 7 can be replaced by conventional electric driving wheels to drive the protective frame to move along the ground rail 6.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
