DETAILED DESCRIPTION

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Please also read Figures 1 to 11 , a construction pit protection device provided by the present invention is now described. The construction pit protection device comprises a plurality of guardrails 1, and adjacent guardrails 1 are connected by connectors 2; each guardrail 1 comprises a baffle 3, two columns 4 and two groups of uprights 5; the baffle 3 is divided into a first supporting structure 31 and a second supporting structure 32 along its length direction, and the first supporting structure 31 and the second supporting structure 32 are staggered along the thickness direction of the baffle 3; the two uprights 4 are respectively located at the two ends of the baffle 3; each upright 4 is hingedly connected to the baffle 3 through a hinge structure near the bottom end, and the two uprights 4 can be rotated separately Turn to a horizontal position and are respectively located on both sides of the baffle 3; a cross bar 6 is detachably provided between the two columns 4; two groups of vertical poles 5 are respectively arranged on the first supporting structure 31 and the second supporting structure 32; each group of vertical poles 5 includes a plurality of vertical poles 5, and the bottom end of each vertical pole 5 is hinged to the top of the baffle 3; the vertical poles 5 and the cross bar 6 are detachably connected; wherein, each vertical pole 5 has a tilted storage state, the vertical poles 5 of the first supporting structure 31 face the second supporting structure 32, and the vertical poles 5 of the second supporting structure 32 face the first supporting structure 31.

[0021] The present invention provides a construction pit protection device. Compared with the prior art, the baffle plate 3 is arranged as a first supporting structure 31 and a second supporting structure 32 that are staggered. Therefore, when the guardrail 1 is stored, the vertical rod 5 on the first supporting structure 31 can be flipped toward the direction of the second supporting structure 32, and the vertical rod 5 on the second supporting structure 32 can be flipped toward the direction of the first supporting structure 31; after the vertical rod 5 is flipped, it is prevented that the vertical rod 5 extends out of the baffle plate 3 in the length direction; the two vertical columns 4 can be rotated to the two sides of the baffle plate 3 respectively, so as to realize the process of storing the guardrail 1; through the above-mentioned arrangement of the present application, when the guardrail 1 is transported, the space occupied by the guardrail 1 can be reduced, thereby improving the space utilization rate.

[0022] It should be noted that the distance between the two columns 4 is less than 2 meters, and the length of a single column 5 is less than half the length of the baffle 3; when the column 5 is in a vertical state, the total height of the column 5 and the baffle 3 is greater than 1.2 meters. Although the baffle 3 has a first support structure 31 and a second support structure 32 that are staggered, the side projections of the two columns 4 overlap.

[0023] Exemplarily, after the upright 5 is folded at a preset angle and the column 4 is rotated to the side of the baffle 3, the cross bar 6 is placed on one side of the baffle 3. The cross bar 6, the upright 4 and the baffle 3 can be fixed together by a binding rope, or by bolts and nuts. During transportation, the possibility of the upright 4 and the cross bar 6 being lost is reduced.

[0024] Exemplarily, each guardrail 1 further includes a top rod 7, and the tops of the two columns 4 are respectively provided with grooves 41 for plugging and matching with the top rod 7; after the top rod 7 is plugged and matched with the column 4, the top rod 7 is fixed to the column 4 by bolts. The top rod 7 is fixed with an insert block 71 at the position of each column 5, and the top of each column 5 is provided with a connecting groove 51. After the insert block 71 is plugged and matched with the connecting groove 51, the insert block 71 is fixed to the column 5 by bolts and nuts. When stored, the top rod 7 is placed on one side of the baffle 3, and the top rod 7 is fixed to the baffle 3 by binding ropes or the cooperation of bolts and nuts.

[0025] In some embodiments, Figures 1 to 11 As shown, the top of the baffle 3 is connected with a hinge seat 33 corresponding to the vertical rod 5 one by one, and the bottom end of each vertical rod 5 has a slide groove 52, and a limiting component 53 is arranged in the slide groove 52. The limiting component 53 is relatively fixed to the vertical rod 5 in the width direction and the thickness direction, and the limiting component 53 is slidably matched with the vertical rod 5 in the length direction; wherein, the top of the baffle 3 has a first slot 34 and a second slot 35 aligned with the limiting component 53, the first slot 34 is vertically arranged, and the second slot 35 is inclined.

[0026] It should be noted that, when the upright pole 5 is in normal use, the upright pole 5 is in a vertically set state. At this time, the limiting component 53 is plugged into and matched with the first slot 34 on the baffle 3, which can limit the rotation of the upright pole 5 around the hinge seat 33, thereby improving the stability of the upright pole 5 during use; when the upright pole 5 needs to be stored, the upright pole 5 is in an inclined state. At this time, the limiting component 53 is plugged into and matched with the second slot 35, which can also limit the rotation of the upright pole 5 around the hinge seat 33, thereby making the upright pole 5 always in a tilted state; through the above-mentioned setting of the present application, when the operator does not operate the limiting component 53, the limiting component 53 can always be plugged into and matched with the first slot 34, or plugged into and matched with the second slot 35.

[0027] In order to facilitate the operator to slide the limiting component 53, a pull rope 36 is fixedly arranged on the limiting component 53, and the top of the slide groove 52 is provided with a hole for the pull rope 36 to pass through, and the hole at the top of the slide groove 52 is connected to the side of the vertical pole 5; the other end of the pull rope 36 passes through the hole at the top of the slide groove 52 and then passes through the side of the vertical pole 5; a blocking part 37 is fixedly arranged on the outer end of the pull rope 36 to reduce the situation where the pull rope 36 completely enters the slide groove 52; through the above arrangement, no matter whether the vertical pole 5 is in a vertical state or an inclined state, the operator can drive the limiting component 53 to slide through the pull rope 36, thereby separating the limiting component 53 from the first slot 34, or separating the limiting component 53 from the second slot 35.

[0028] In some embodiments, Figures 1 to 11 As shown, the slide groove 52 is connected to one side of the vertical rod 5 , a guide groove 54 is provided on the side wall of the slide groove 52 , and a protrusion 55 slidably matched with the guide groove 54 is provided on the side of the limiting component 53 .

[0029] It should be noted that the limiting component 53 can limit the position between the upright pole 5 and the limiting component 53 by slidingly cooperating with the guide groove 54 through the protrusion 55, so that the limiting component 53 can only slide along the slide groove 52.

[0030] In some embodiments, Figures 1 to 11 As shown, the slide groove 52 is connected to one side of the vertical rod 5 to form an opening; one side of the limiting component 53 is located at the opening position of the slide groove 52 and is coplanar with the vertical rod 5; wherein, the side of the limiting component 53 located at the opening position has a plurality of pulling grooves 531.

[0031] It should be noted that when the vertical pole 5 is set vertically, the operator can slide the limiting component 53 upward according to the pulling groove 531 on the limiting component 53, thereby separating the limiting component 53 from the first slot 34; the operator can also pull the pull rope 36 to separate the limiting component 53 from the first slot 34.

[0032] In some embodiments, Figures 1 to 11As shown, the hinge structure includes a connecting seat 8, which is arranged on the side of the column 4 facing the baffle 3, and a hinge block 81 is provided on the connecting seat 8, and the hinge block 81 is hingedly matched with the hinge seat 33 through a first hinge shaft 82; one side of the hinge block 81 has a spherical hinge hole, and a hinge ball 83 is provided in the spherical hinge hole; the hinge ball 83 is connected to a second hinge shaft 84 perpendicular to the first hinge shaft 82, and the other end of the second hinge shaft 84 is connected to the end of the baffle 3; the top of the connecting seat 8 has an avoidance groove 85 for avoiding the second hinge shaft 84.

[0033] It should be noted that when rotating the column 4 to the side of the baffle 3, the column 4 and the hinge block 81 are first rotated 90 degrees around the second hinge shaft 84 to set the column 4 horizontally, and the first hinge shaft 82 is set vertically; then the column 4 is rotated 90 degrees around the first hinge shaft 82 to rotate the column 4 to one side of the baffle 3; through the above arrangement, the vertically arranged column 4 can be rotated to one side of the baffle 3, thereby reducing the space occupied by the guardrail 1 as a whole. By setting the avoidance groove 85 on the connecting seat 8, the second hinge shaft 84 can be located in the avoidance groove 85 during the rotation of the column 4 around the first hinge shaft 82, thereby avoiding interference between the second hinge shaft 84 and the connecting seat 8.

[0034] In some embodiments, Figures 1 to 11 As shown, the connecting member 2 is a T-shaped structure, and the connecting member 2 can connect two guardrails 1 arranged in parallel, or connect two guardrails 1 arranged perpendicular to each other.

[0035] It should be noted that the connector 2 has a through hole, and the column 4 has a hole aligned with the through hole on the connector 2. When connecting two adjacent columns 4 through the connector 2, the two holes on the connector 2 are aligned with the holes on the two columns 4, and then the bolts are passed through the connector 2 and the column 4, and the connector 2 can be fixed on the column 4 by tightening the nut, thereby connecting the columns 4 on the two guardrails 1. By setting the connector 2 as a T-shaped structure, the connector 2 can connect the two columns 4 regardless of whether the guardrails 1 are arranged in parallel or vertically, thereby improving the applicability of the connector 2.

[0036] In some embodiments, Figures 1 to 11 As shown, each column 4 is connected to a fixing plate 42, and the fixing plate 42 has a through hole; the baffle 3 has a connecting hole aligned with the through hole on the fixing plate 42; wherein, when the column 4 is rotated to one side of the baffle 3, the through hole on the fixing plate 42 is aligned with the connecting hole on the baffle 3, and the fixing plate 42 is fixed to the baffle 3 by bolts and nuts.

[0037] It should be noted that when the column 4 is rotated to one side of the baffle 3, the through hole on the fixing plate 42 is aligned with the connecting hole on the baffle 3. At this time, the column 4 can be fixed to the baffle 3 by passing the bolts through the fixing plate 42 and the baffle 3 and tightening the nuts. During transportation, the movement of the column 4 relative to the baffle 3 can be reduced, thereby reducing the damage to the hinge position between the column 4 and the baffle 3.

[0038] In some embodiments, Figures 1 to 11 As shown, the baffle 3 has several connecting plates 38 near the bottom, each of which has a mounting hole; the connecting plates 38 are fixed to the ground by bolts; a mounting plate 43 is fixed to the bottom of the column 4, and the mounting plate 43 has a through hole; the mounting plate 43 is fixed to the ground by bolts.

[0039] It should be noted that, by arranging the connecting plate 38 on the baffle 3, after the baffle 3 is placed in the installation position, the mounting holes on the connecting plate 38 are plugged into and matched with the embedded bolts, and the embedded bolts pass through the connecting plate 38. By tightening the nuts, the connecting plate 38 can be fixed to the ground. The installation process of the mounting plate 43 on the column 4 is the same as the installation process of the connecting plate 38, which will not be repeated here. Through the above-mentioned setting of the present application, the connection between the baffle 3 and the ground can be strengthened, thereby improving the overall protective performance of the guardrail 1.

[0040] In some embodiments, Figures 1 to 11 As shown, the cross bar 6 includes two sections of connecting rods parallel to each other, and the two connecting rods are connected by a diagonal rod; the two sections of connecting rods are respectively connected to the vertical rods 5 on the first supporting structure 31 and the second supporting structure 32; wherein the two ends of the cross bar 6 are respectively connected to the two vertical columns 4.

[0041] It should be noted that the side wall of the column 4 has a groove that is plugged with the end of the crossbar 6, and there is a through hole at the bottom of the groove. The position corresponding to the through hole at the bottom of the groove on the crossbar 6 also has a through hole. After the crossbar 6 and the column 4 are plugged, the crossbar 6 can be fixed to the column 4 by bolts and nuts; the crossbar 6 has a through hole at the position of each vertical pole 5, and the vertical pole 5 also has a corresponding through hole; by passing the bolt through the crossbar 6 and the vertical pole 5, and by tightening the nut, each vertical pole 5 can be fixed to the crossbar 6. Through the above-mentioned configuration of the present application, the connection strength of the vertical pole 5 can be improved, thereby improving the overall protection performance.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
