[0022] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings, but this does not limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0023] The present embodiment describes a foundation pit safety protection device for municipal engineering construction, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, it includes several vertically arranged upright poles 1, and a base 11 is provided at the bottom of the upright pole 1. The base 11 has a certain weight and can be made of concrete or made of metal. The base 11 can increase the stability of the upright pole 1 and prevent the upright pole 1 from tipping over. A cross bar 3 is horizontally provided between two adjacent upright poles 1, and the upright poles 1 are connected by the cross bar 3.

[0024] Two cross bars 3 are arranged between two adjacent vertical poles 1, and the two cross bars 3 are parallel up and down. The two cross bars 3 can better block the area between the two vertical poles 1, and the two cross bars 3 can facilitate the hanging of the grid plate 8. After the grid plate 8 is hung on the upper cross bar 3, the lower cross bar 3 can block the bottom of the grid plate 8, which can reduce the swinging of the grid plate 8 when hanging on the cross bar 3.

[0025] Both ends of the cross bar 3 are independently sleeved with a first sleeve 4, that is, each cross bar 3 is sleeved with two first sleeves 4, and a first threaded hole is provided on the front side of the first sleeve 4, and a first bolt 7 is provided in the first threaded hole to be threadedly matched with it. The screw of the first bolt 7 passes through the first threaded hole and presses on the cross bar 3, thereby fixing the cross bar 3 in the first sleeve 4. This paragraph of text as a whole constitutes a locking assembly that fixes the first sleeve 4 and the cross bar 3; of course, in some embodiments, the locking assembly can also be a first latch, and a fourth through hole for the first latch to pass through is provided on the front side wall of the first sleeve 4, and a third groove for inserting the first latch is provided at the end of the cross bar 3. The first latch passes through the fourth through hole and is located in the third groove to prevent the end of the cross bar 3 from sliding horizontally in the first sleeve 4, thereby fixing the cross bar 3 and the first sleeve 4.

[0026] Fixed blocks 6 are horizontally provided on the upper and lower sides of the first sleeve 4. The fixed blocks 6 are connected to the vertical poles 1. The two fixed blocks 6 are parallel to each other. The first sleeve 4 is located between the two fixed blocks 6 and rotates horizontally, thereby adjusting the angle between the cross bar 3 and the vertical pole 1. The position between the two adjacent vertical poles 1 can also be adjusted, so that the cross bar 3 and the vertical pole 1 can be adjusted according to the shape of the foundation pit, so that the cross bar 3 and the vertical pole 1 can better protect the foundation pit.

[0027] A rotating shaft 5 is provided between the fixed block 6 and the first sleeve 4. One end of the rotating shaft 5 is fixed to the fixed block 6. A first groove is provided on the outer wall of the first sleeve 4 for the other end of the rotating shaft 5 to be inserted and rotated freely. The top of the upper rotating shaft 5 is fixed to the bottom of the upper fixed block 6, and the bottom end of the lower rotating shaft 5 is fixed to the top of the lower fixed block 6. A first groove for inserting the rotating shaft 5 is provided on the upper and lower side walls of the first sleeve 4. The first groove is a circular structure. Preferably, the outer wall of the first sleeve 4 is a rectangular structure, and the inner wall of the first sleeve 4 is circular, so that the first groove is provided on the outer wall of the first sleeve 4. A bearing is provided between the rotating shaft 5 and the first groove. The outer wall of the bearing The ring is fixed to the first groove, and the inner ring of the bearing is fixedly sleeved on the rotating shaft 5. The rotating shaft 5 is connected to the first sleeve 4 through the bearing, and the first sleeve 4 is also rotated horizontally between the two fixed blocks 6 through the bearing, thereby adjusting the angle between the crossbar 3 and the vertical pole 1, and also adjusting the position between the two adjacent vertical poles 1, so that the shape of the combination of the vertical pole 1 and the crossbar 3 is consistent with the shape of the foundation pit; of course, in some embodiments, one end of the rotating shaft 5 can also be fixed to the outer wall of the first sleeve 4, the first groove is opened on the fixed block 6, and the rotating shaft 5 is connected to the fixed block 6 through the bearing, so that the first sleeve 4 can also rotate horizontally between the two fixed blocks 6. This paragraph as a whole constitutes a rotating assembly for horizontally rotating the first sleeve 4.

[0028] Two second sleeves 2 are sleeved on each of the vertical rods 1. A bolt for fixing the second sleeve 2 to the vertical rod 1 is provided on the second sleeve 2. A second threaded hole that is in threaded fit with the screw rod of the bolt is formed in the rear side of the second sleeve 2. The screw rod of the bolt passes through the second threaded hole and abuts against the vertical rod 1, so as to fix the second sleeve 2 on the vertical rod 1. Since two cross rods 3 are provided between two adjacent vertical rods 1, two first sleeves 4 are provided on each vertical rod 1. The two second sleeves 2 respectively correspond to the first sleeves 4 on the cross rods 3. The first sleeve 4 and the fixing block 6 are detachably fitted with the vertical rod 1 through the bolt and the second sleeve 2, which can reduce the protrusion of the first sleeve 4 and the fixing block 6 on the vertical rod 1, facilitate the stacking of the vertical rods 1 during transportation, reduce the stacking space occupied by the vertical rods 1, increase the total number of transported items, and thus facilitate transportation. The fixing block 6 is fixed to the outer side wall of the second sleeve 2 through a connecting plate 14. The connecting plate 14 can provide a distance between the fixing block 6 and the second sleeve 2, so that there is a gap between the first sleeve 4 and the second sleeve 2, preventing the second sleeve 2 from hindering the rotation of the first sleeve 4.

[0029] The vertical rod 1 has a rectangular structure, and the inner side wall of the second sleeve 2 has a rectangular structure. When the inner side walls of the vertical rod 1 and the second sleeve 2 are rectangular structures, the second sleeve 2 can only slide up and down on the vertical rod 1, which can reduce the rotation of the second sleeve 2 on the vertical rod 1 and make the fixing effect of the bolt on the second sleeve 2 better.

[0030] A grid plate 8 is provided on the cross rod 3. The grid plate 8 is a metal plate. The grid plate 8 can enclose the area between two adjacent vertical rods 1 to increase the protection effect. A warning sign 9 is provided on one side of the grid plate 8. The warning sign 9 is a metal plate and is fixed to the grid plate 8, such as by welding. Warning words, such as "Danger Ahead, Keep Away", are written on the warning sign 9, and a reflective material is coated on the warning sign 9, which can also play a warning role at night.

[0031] The grid plate 8 is connected to the cross rod 3 through a buckle 10. The buckle 10 includes two horizontally parallel plates and a vertically arranged plate, as Figure 4 shown, and the buckle 10 is integrally in a "C" - shaped structure. The outer diameter of the cross rod 3 is smaller than the distance between the two horizontally parallel plates of the buckle 10, so that the cross rod 3 can be located between the two horizontally parallel plates of the buckle 10. Two first through - holes for the two horizontally parallel plates of the buckle 10 to pass through are formed on the grid plate 8. The two first through - holes on the grid plate 8 are independent of each other. A second hole that communicates up and down is formed on one of the horizontally parallel plates, and a second through - hole is formed on the upper parallel plate. Of course, due to the shape of the buckle 10, the second through - hole can be formed on any horizontally parallel plate. During use, only the plate with the second through - hole needs to be located above. A pin 13 is arranged in the second through - hole. The shape of the pin 13 is as Figure 5As shown, the diameter of the middle and lower part of the latch 13 is smaller than the diameter of the top end, and the second through hole is used for the middle and lower part of the latch 13 to pass through. The diameter of the second through hole is smaller than the diameter of the top end of the latch 13, which can prevent the top end of the latch 13 from falling from the second through hole. The two upper and lower parallel plates of the buckle 10 pass through the first through hole on the mesh plate 8, and the upper cross bar 3 is located between the two upper and lower parallel plates of the buckle 10, and then the latch 13 is inserted into the second through hole of the parallel plates of the buckle 10, so that the vertical plate of the buckle 10 contacts the front side wall of the mesh plate 8, and the buckle 10 can be prevented from detaching from the cross bar 3 by the latch 13, so that the mesh plate 8 and the cross bar 3 are connected by the buckle 10. This paragraph as a whole makes the mesh plate 8 and the cross bar 3 detachable, so that during transportation, the mesh plate 8 can be removed from the cross bar 3, which facilitates the separate overlapping stacking of the cross bar 3 and the mesh plate 8, facilitates the rational use of the transportation space, and further facilitates transportation; of course, in some embodiments, a hook can be provided on the rear side of the mesh plate 8, and the mesh plate 8 can be hung on the upper cross bar 3 through the hook.

[0032] The base 11 is provided with a third through hole for the bottom end of the upright 1 to pass through. When the upright 1 is a rectangular rod, the third through hole is a rectangular structure. The bottom end of the upright 1 passes through the second through hole to fix a limiting plate 12. The limiting plate 12 is used to prevent the bottom end of the upright 1 from passing through the third through hole. The limiting plate 12 is a rectangular structure. The length and width of the third through hole are smaller than the length and width of the limiting plate 12. The limiting plate 12 is prevented from passing through the third through hole, thereby preventing the bottom end of the upright 1 from passing through the third through hole. In this way, the upright 1 can be prevented from being lifted from the top of the base 11. The bottom of the base 11 is provided with a second groove for the retaining plate 12 to be embedded. The depth of the second groove is consistent with the thickness of the retaining plate 12. When the retaining plate 12 is located in the second groove, the ground of the retaining plate 12 is flush with the ground of the base 11. This makes the upright 1 and the base 11 detachable. When transporting, the top of the upright 1 is removed from the third through hole on the base 11, thereby disassembling the upright 1 and the base 11, which is more convenient. Compared with the base 11, the retaining plate 12 is smaller in size, making it easier to stack. Of course, in some embodiments, the upright 1 and the retaining plate 12 can also be detachable. The outer wall of the bottom end of the upright 1 is provided with an external thread, and the retaining plate 12 is provided with a thread groove for threadedly mating with the external thread at the bottom end of the upright 1, so that the upright 1 and the retaining plate 12 are threadedly mated. The retaining plate 12 and the upright 1 can also be disassembled for transportation.

[0033] Working principle:

[0034] When in use, the second sleeve 2 is put on the vertical pole 1, and the second sleeve 2 and the vertical pole 1 are fixed by bolts. Then, the end of the cross bar 3 is inserted into the first sleeve 4, and the cross bar 3 is fixed in the first sleeve 4 by the first bolt 7, so that the cross bar 3 connects the vertical pole 1. Moreover, according to the edge shape of the foundation pit, the position between the two adjacent vertical poles 1 can be adjusted by horizontally rotating the first sleeve 4 between the fixing blocks 6, that is, the angle between the cross bar 3 and the vertical pole 1 can be adjusted so that the shape formed by the cross bar 3 and the vertical pole 1 is consistent with the shape of the foundation pit, so that the vertical pole 1 and the cross bar 3 protect the foundation pit, and the cross bar 3 is connected to the vertical pole 1 by the fixing blocks 6, the second sleeve 2, the first sleeve 4 and the cross bar 3, so that the overall stability is higher, and the vertical pole 1 can be reduced. The misalignment with the vertical pole 1 is reduced, thereby reducing the gap between the adjacent vertical poles 1 and the cross bar 3, and the protection effect on the foundation pit is better; the cross bar 3 and the first sleeve 4 can be disassembled by the first bolt 7, and the second sleeve 2 and the vertical pole 1 can be disassembled by the bolt, and the vertical pole 1 and the base 11 can be disassembled by the limit plate 12, and the grid plate 8 and the cross bar 3 can be disassembled by the buckle 10, so that the base 11, the vertical pole 1, the cross bar 3 and the grid plate 8 can be stacked separately, and when the base 11, the vertical pole 1, the cross bar 3 and the grid plate 8 are stacked separately, the shapes of the same parts are consistent, and they are all separate rods and plates, with fewer protruding parts, which are convenient for overlapping placement, can reduce the occupied transportation space, and facilitate the rational use of space, thereby facilitating transportation.
