Description

Technical Field

[0001] The present application relates to the field of isolation devices, and in particular to an engineering isolation fence. Background Art

[0002] Currently, on the outside of a construction site, an isolation fence is generally set up to isolate non-staff on the outside, thereby reducing the occurrence of injuries to non-staff caused by non-staff entering the construction site.

[0003] The current isolation fence generally adopts a foldable form, with multiple support rods staggered and spliced into a rectangle, and the deformation ability of the rectangle is utilized to increase the isolation range.

[0004] However, since the currently used isolation fence is generally a single-layer structure and the isolation fence needs to be stretched, it is easy for the isolation fence to bend when it is impacted by the outside or pressure is applied to the middle position of the isolation fence by the outside, making it difficult to fully isolate non-staff outside the isolation fence. Summary of the Utility Model

[0005] In order to increase the ability of the isolation fence to withstand external impacts, the present application provides an engineering isolation fence.

[0006] The engineering isolation fence provided by the present application adopts the following technical solution:

[0007] An engineering isolation fence includes a fixed pile. A plurality of sliding grooves are formed in one side wall of the fixed pile along the length direction of the fixed pile, and every two adjacent sliding grooves are communicated. An expansion rod is provided inside each sliding groove, and one end of each expansion rod is rotationally and slidably connected to the groove wall of the sliding groove. The other end of each expansion rod is rotatably connected with a plurality of fixed support rods. A plurality of clamping grooves parallel to the sliding grooves are formed in the side of the fixed pile away from the side where the sliding grooves are formed, and the end of the expansion rod away from the connection with the inner wall of the clamping groove and the plurality of fixed support rods connected thereto can be inserted into different clamping grooves formed in an adjacent fixed pile and connected to the groove wall of the clamping groove.

[0008] By adopting the above technical solution, when it is necessary to set up isolation fences to isolate a certain construction site, multiple fixed piles are arranged at intervals. Then, multiple telescopic rods on one side of each fixed pile are slid into the sliding grooves opened at the middle position on one side of the fixed pile, and the multiple telescopic rods connected to the same fixed pile are arranged at intervals. One end of each telescopic rod is inserted into the clamping groove of an adjacent fixed pile, and the fixed support rods connected to the end of each telescopic rod are inserted into different clamping grooves, so as to realize the connection between two adjacent fixed piles. And because the telescopic rods and the fixed support rods are inserted into different clamping grooves, a stable triangular structure is formed between the fixed support rods, the telescopic rods and the side walls of the fixed piles, thus reducing the damage of the connection between the two fixed piles under the action of external forces, and avoiding the phenomenon that the isolation effect of the isolation fence is reduced.

[0009] Optionally, the telescopic rod includes a third rod rotatably connected to multiple fixed support rods, and a limiting member capable of restricting the position of the third rod or the fixed support rod inserted into the clamping groove is rotatably connected inside each clamping groove.

[0010] By adopting the above technical solution, due to the existence of the limiting member, the phenomenon that multiple telescopic rods connected to the same fixed pile move to the lower side of two adjacent fixed piles during actual use, thus reducing the isolation effect of the area between the two adjacent fixed piles, is avoided.

[0011] Optionally, the limiting member includes a limiting block slidably inserted into the inner walls of two opposite side walls of the clamping groove. Each limiting block is connected with a pressure spring capable of driving the limiting block to move, and each limiting block can be inserted into the adjacent third rod or the fixed support rod.

[0012] By adopting the above technical solution, when the third rod or the fixed support rod is inserted into the clamping groove, the multiple limiting blocks connected inside the clamping groove can be inserted into the third rod or the fixed support rod under the drive of the pressure spring, thus reducing the phenomenon that the third rod or the fixed support rod moves.

[0013] Optionally, one end of each telescopic rod connected to the groove wall of the sliding groove is connected with a fixing component capable of restricting the relative position between the telescopic rod and the groove wall of the connected sliding groove.

[0014] By adopting the above technical solution, due to the existence of the fixing component, the phenomenon that the telescopic rod moves to the position close to the ground between two adjacent fixed piles when connecting the two adjacent fixed piles, thus reducing the position isolation effect between the two adjacent fixed piles, is avoided.

[0015] Optionally, the fixing component includes a connection block rotatably connected to one end of the telescopic rod away from the third support rod in a vertical plane. The connection block is rotatably inserted with a sliding block, and the sliding block can slide inside the sliding groove. One end of the connection block located inside the sliding groove is fixedly connected with a driving bevel gear, and the driving bevel gear meshes with two oppositely arranged driven bevel gears. A fixing lead screw is threadedly inserted through the middle position of each driven bevel gear. The end of each fixing lead screw is fixedly connected with a fixing block capable of restricting the rotation of the fixing lead screw, and each fixing block is slidably inserted into the sliding block and can move out of the sliding block to abut against the inner wall of the clamping groove.

[0016] By adopting the above technical solution, when it is necessary to fix the position of one end of the telescopic rod located inside the connected sliding groove, rotate the telescopic rod. The telescopic rod drives the connected connection block to rotate, the connection block drives the driving bevel gear to rotate, the driving bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the fixing lead screw to move. During the movement of the fixing lead screw, the fixing block is driven to move, so that the fixing block can abut against the groove wall of the adjacent clamping groove, thereby realizing the restriction of the positions of the sliding block, the connection block and the end of the telescopic rod.

[0017] Optionally, straps capable of being connected to each other and restricting the position of the telescopic rod inside the sliding groove are fixedly connected to two oppositely arranged side walls of the fixing pile.

[0018] By adopting the above technical solution, due to the existence of the straps, when the staff transports the fixing pile, the telescopic rod can be restricted inside the sliding groove through the straps, thereby reducing the space occupied by the fixing pile and the connected telescopic rod during the transportation or placement of the fixing pile.

[0019] Optionally, one side of each fixing block capable of abutting against the groove wall of the sliding groove is provided with serrations.

[0020] By adopting the above technical solution, since one side of the fixing block abutting against the groove wall of the sliding groove is provided with serrations, in the actual use process, when the fixing block abuts against the groove wall of the sliding groove, the relative position between the connected telescopic rod and the groove wall of the sliding groove can be better restricted.

[0021] Optionally, a fixing plate is fixedly connected to the bottom of the fixing pile, and the fixing plate is connected with a fixing bolt capable of restricting the position of the fixing plate.

[0022] By adopting the above technical solution, due to the existence of the fixing plate and the fixing bolt, when placing the fixing pile, the position of the fixing pile can be restricted through the fixing plate and the fixing bolt, thereby reducing the occurrence of the phenomenon that it is difficult to isolate the construction site due to the position deviation of the fixing pile.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Due to the existence of the telescopic rod and the fixed support rod connected to the end of the telescopic rod, during actual use, the phenomenon that the telescopic rod undergoes position deviation under pressure, resulting in the inability to fully isolate the construction site on one side of the fixed pile, is reduced;

[0025] 2. Through the mutual cooperation of the limiting member and the fixing component, the relative positions of two adjacent fixed piles can be restricted, thereby reducing the phenomenon that the telescopic rod moves downward under the action of gravity during actual use, resulting in a reduction in the isolation effect between two adjacent fixed piles;

[0026] 3. Due to the existence of the binding strap, the positions of the fixed pile and the multiple telescopic rods connected to the fixed pile can be restricted, thus facilitating the handling and placement of the fixed pile by the staff. Description of the Drawings

Detailed Description of the Embodiment

[0033] The following is a further detailed description of the present application with reference to the attached Figure 1 - attached Figure 5 drawings.

[0034] An embodiment of the present application discloses an engineering isolation fence. Referring to Figure 1 , it includes a fixed pile 1. A plurality of sliding grooves 11 are opened on one side of the fixed pile 1. In this embodiment, the number of sliding grooves 11 is set to three, and each sliding groove 11 is arranged along the length direction of the fixed pile 1. A communication groove 12 capable of communicating the two sliding grooves 11 is opened between the upper ends of two adjacent sliding grooves 11. A telescopic rod 2 is provided inside each sliding groove 11.

[0035] Each telescopic rod 2 is provided to include a first support rod 21. One end of each first support rod 21 is rotatably and slidably connected to the groove wall of the sliding groove 11. A second support rod 22 is slidably inserted along the length direction of the first support rod 21 inside one end of each first support rod 21 away from the connection with the groove wall of the sliding groove 11. A third support rod 23 is slidably inserted inside one end of each second support rod 22 away from the first support rod 21. A positioning bolt 24 capable of passing through the first support rod 21 and the second support rod 22 at the same time is connected to one end of each first support rod 21 close to the second support rod 22, and a positioning bolt 24 capable of passing through the second support rod 22 and the third support rod 23 at the same time is connected to one end of each second support rod 22 close to the third support rod 23.

[0036] Two relatively arranged fixed support rods 3 are rotatably connected to each third support rod 23, and each third support rod 23 and the two connected fixed support rods 3 can be placed inside the sliding groove 11 at the same time.

[0037] Referring to Figure 1 and Figure 2 , a plurality of clamping grooves 13 are opened along the length direction of the fixed pile 1 on one side of each fixed pile 1 away from the sliding groove 11. In this embodiment, the number of clamping grooves 13 is set to three, and the three clamping grooves 13 are opened corresponding to the three sliding grooves 11 one by one. Each third support rod 23 and the two connected fixed support rods 3 can be inserted into different clamping grooves 13, and a limiting member 4 capable of limiting the position of the third support rod 23 or the fixed support rod 3 inserted into the clamping groove 13 is provided inside each clamping groove 13.

[0038] When the isolation fence is needed, a plurality of fixed support rods 3 are arranged around the construction site in sequence. Then, the three telescopic rods 2 connected to one of the fixed piles 1 are all slid into the inner sliding groove 11 in the middle through the communication grooves 12. Then, the three telescopic rods 2 are arranged at intervals inside the sliding groove 11, and the relative positions between each telescopic rod 2 and the connected sliding groove 11 are fixed. Then, the relative positions between the first support rod 21, the second support rod 22, and the third support rod 23 are adjusted so that the end of the third support rod 23 away from the second support rod 22 can be inserted into the clamping groove 13 in the middle position on one side of the adjacent fixed pile 1, and the relative position between the third support rod 23 and the groove wall of the inserted clamping groove 13 is restricted by the limiting member 4.

[0039] Then, rotate the two fixed support rods 3 connected to each third support rod 23 so that the two fixed support rods 3 are both inserted into the clamping grooves 13 on both sides of the clamping groove 13 into which the third support rod 23 is inserted, and the relative position between the fixed support rod 3 and the groove wall of the inserted clamping groove 13 is restricted by the limiting member 4.

[0040] Due to the existence of the fixed support rod 3 and the limiting member 4, the positions of the plurality of telescopic rods 2 can be restricted, so that in the actual use process, the telescopic rods 2 can be more stable when bearing external impacts.

[0041] Refer to Figure 3 and Figure 4 As shown in [figures] and [figures], the limiting member 4 includes a plurality of limiting blocks 41 slidably inserted into the inner parts of the two opposite groove walls of the clamping groove 13, and the plurality of limiting blocks 41 on the groove wall of each clamping groove 13 are evenly arranged at a certain distance from each other. One end of each limiting block 41 located inside the groove wall of the clamping groove 13 is fixedly connected with a compression spring 42, and one end of each compression spring 42 away from the limiting block 41 is fixedly connected with the groove wall of the clamping groove 13.

[0042] Two relatively arranged first limiting grooves 231 for the limiting blocks 41 to be inserted are formed at the end of each third support rod 23 away from the second support rod 22, and two relatively arranged second limiting grooves 31 for the limiting blocks 41 to be inserted are formed at the end of each fixed support rod 3 away from the connection with the third support rod 23.

[0043] When the third support rod 23 or the fixed support rod 3 is inserted into the limiting groove, the limiting block 41 can be inserted into the first limiting groove 231 or the second limiting groove 31 under the drive of the compression spring 42, so as to realize the restriction of the relative position between the third support rod 23 or the fixed support rod 3 and the groove wall of the clamping groove 13.

[0044] Refer to Figure 5, a fixing assembly 5 is connected to one end of each first rod 21 away from the second rod 22, and each fixing assembly 5 can limit the relative position between the first rod 21 and the groove wall of the sliding groove 11.

[0045] Due to the existence of the fixing assembly 5, the first rod 21 can limit the relative position between the first rod 21 and the groove wall of the sliding groove 11 through the fixing assembly 5, so that the telescopic rod 2 can be more stable during the process of connecting two adjacent fixing piles 1.

[0046] The fixing assembly 5 includes a connecting block 51 rotatably connected to the first rod 21, and each first rod 21 can rotate in a plane perpendicular to the side wall of the adjacent fixing pile 1. A sliding block 52 is rotatably inserted at one end of the connecting block 51 away from the first rod 21. The sliding block 52 is slidably inserted into the sliding groove 11 and can slide in different sliding grooves 11 through the communication groove 12.

[0047] A cavity is provided inside the sliding block 52. A driving bevel gear 53 is rotatably connected to one end of the connecting block 51 located inside the sliding groove 11. The driving bevel gear 53 meshes with two driven bevel gears 54. The driving bevel gear 53 and the two driven bevel gears 54 are both arranged inside the cavity. The two driven bevel gears 54 are arranged oppositely on both sides of the driving bevel gear 53. A bearing with the same axis as the driven bevel gear is fixedly sleeved on the outer side wall of the driven bevel gear. The inner ring of the bearing is fixedly sleeved on the outer side wall of the driven bevel gear, but does not affect the meshing position of the driven bevel gear 54 and the driving bevel gear 53. The outer side wall of the outer ring of the bearing is fixed on the inner wall of the cavity, and the two driven bevel gears 54 are arranged in one-to-one correspondence with the two oppositely arranged groove walls of the sliding groove 11. Each driven bevel gear 54 is penetrated through the middle position and threadedly connected with a fixing lead screw 55. One end of each fixing lead screw 55 close to the groove wall of the corresponding sliding groove 11 is fixedly connected with a fixing block 56. Each fixing block 56 is slidably inserted into the cavity of the sliding block 52 and can move out of the cavity of the sliding block 52 and abut against the groove wall of the corresponding sliding groove 11. One side of each fixing block 56 away from the connected fixing lead screw 55 is provided with serrations.

[0048] When it is necessary to fix the position of the first rod 21, rotate the first rod 21. The first rod 21 drives the connecting block 51 to rotate. During the rotation of the connecting block 51, the driving bevel gear 53 is driven to rotate. The driving bevel gear 53 drives the two engaged driven bevel gears 54 to rotate. The bearing limits the horizontal direction of the driven bevel gear 54, so that the driven bevel gear 54 can only rotate and cannot move horizontally. When the driven bevel gear 54 rotates, it drives the inner ring of the bearing to rotate. Since the fixing lead screw 55 is fixedly connected with the fixing block 56, both of the two driven bevel gears 54 can drive the connected fixing lead screw 55 to move during the rotation process. The fixing lead screws 55 on both sides move relative to each other during the movement process. When the fixing lead screw 55 moves, it can drive the connected fixing block 56 to move relatively, so that the fixing block 56 can move out of the sliding block 52 and abut against the wall of the corresponding sliding groove 11, thereby realizing the limitation of the position of the first rod 21.

[0049] Referring to Figure 1 , straps 14 are fixedly connected to the positions of the two side walls of the fixing pile 1 where the sliding groove 11 and the clamping groove 13 are not provided, close to the side wall where the sliding groove 11 is provided, and the straps 14 connected to the two side walls are arranged oppositely. On one side of each strap 14 away from the side wall of the connected fixing pile 1, a magic tape 141 is fixedly connected, and the two magic tapes 141 connected to the same fixing pile 1 are arranged correspondingly and can be adhered to each other.

[0050] Due to the existence of the straps 14, when each telescopic rod 2 and the fixed rod 3 are both inside the sliding groove 11, the positions of the telescopic rods 2 inside the sliding groove 11 can be restricted by the mutual adhesion of the two straps 14 on the fixing pile 1, so that the process of carrying the fixing pile 1 can be more convenient.

[0051] A fixing plate 15 is also fixedly connected to the bottom of the fixing pile 1, and a plurality of fixing bolts 16 capable of passing through the fixing plate 15 are connected to each fixing plate 15.

[0052] Due to the existence of the fixing plate 15 and the fixing bolts 16, the position of the fixing pile 1 can be restricted by connecting to the ground through the fixing bolts 16.

[0053] The implementation principle of an engineering isolation fence in an embodiment of the present application is as follows: When it is necessary to fence a construction site, fix the fixing pile 1 at a designated position through the fixing bolts 16, and then adjust the length of the telescopic rod 2 according to the distance between two adjacent fixing piles 1, so that each third rod 23 and the fixed rod 3 can be inserted into the clamping groove 13 of the adjacent fixing pile 1.

[0054] After that, rotate the first rod 21 to fix the positions of each telescopic rod 2, insert each third rod 23 and the two connected fixed rods 3 into different clamping grooves 13, and limit the positions of each third rod 23 and each fixed rod 3 through the limit blocks 41, so as to realize the connection of two adjacent fixed piles 1, and further realize the enclosure of the construction site.

[0055] The above are all preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
