Description

Technical Field

[0001] The present invention belongs to the technical field of water conservancy project construction, and specifically relates to a temporary warning bracket for water conservancy project planning and construction. Background Technique

[0002] During the maintenance of water conservancy infrastructure or water conservancy bridges, it is often necessary to repair damaged roads or bridges. At the construction site of the repair, there are often motor vehicles passing by. In order to protect the safety of construction workers, some warning signs are generally placed not far from the construction site to remind the owners of passing vehicles to pay attention to safety.

[0003] A patent with the publication number CN217267030U discloses a temporary warning bracket for water conservancy project planning and construction, including a base. A fixed column is fixedly connected to the top of the base. A sliding groove is opened at the top of the fixed column. A movable column is slidably connected in the sliding groove. Three warning plates are fixedly connected to the top of the movable column. The utility model can drive the threaded rod to rotate through the rotation of the servo motor. The rotation of the threaded rod drives the movable column to move upward. The movement of the movable column drives the fixed rack to move upward. The movement of the fixed rack drives the rotating gear and the rotating column to rotate. The rotation of the rotating gear drives the movable rack to move downward. The downward movement of the movable rack drives the L-shaped connecting rod, the sliding ring, the fixed rod and the L-shaped support rod to move downward. The movement of the L-shaped support rod drives the support seat to contact the ground. By evenly distributing the support seats around the base, the device is supported, thereby effectively preventing the device from being blown down by the wind.

[0004] For the existing temporary warning brackets for water conservancy project planning and construction, most of the support structures of the devices are relatively simple. In order to increase the stability and contact area of the brackets, the bottom ends of the brackets will extend relatively large, and most of the brackets are welded. As a result, when the brackets are stored and stacked later, the bottom ends of the brackets cannot be recycled. For some brackets with recycling and retraction, their stability is insufficient to extend and support the deployed area, and it is easy to cause the problem that the support area of the bracket is bent under the blowing of the wind, resulting in an unsatisfactory support effect on the device, and it is easy to make the device be blown down by the wind, and thus unable to play a warning role.

[0005] Therefore, the present invention provides a temporary warning bracket for water conservancy project planning and construction. Summary of the Invention

On the outer surface of the swing support arm and at both edge positions in the middle, two sets of sleeve shells are fixedly connected. On the inner wall surfaces of the two sets of sleeve shells, a first elastic wire is fixedly connected. One end of the first elastic wire is fixedly connected with a docking sleeve head and a docking concave head movably sleeved on the inner wall surface of the sleeve shell. One end of the docking sleeve head is movably sleeved on the outer surface of the docking concave head; a docking groove is formed on the inner wall surface of the docking concave head. On the outer surface of the docking sleeve head and at the middle position, an inner liner limiting column is arranged. On the outer surface of the inner liner limiting column and at the middle position, a semi-circular convex head is arranged. The outer surface of the semi-circular convex head is movably sleeved on the outer surface of the docking groove.

[0008] Preferably, an inlaid groove is formed on the outer surface of the support column and at the bottom edge position. One end of the swing support arm is movably sleeved on the top inner wall surface of the inlaid groove. A support pad is fixedly connected to the bottom surface of the support column.

[0009] Preferably, a compression-resistant support rod is swingably connected to the outer surface of the bottom of the support column and at the top edge position of the support pad. The other end of the swing support arm is movably sleeved on the top surface of the compression-resistant support rod. Expansion panels are fixedly connected to both side surfaces of the other end of the compression-resistant support rod.

[0010] Preferably, a return spring wire is fixedly connected to the outer surface of the support column. One end of the return spring wire is arranged at the bottom edge position of the inlaid groove. The other end of the return spring wire is fixedly connected to the top surface of the compression-resistant support rod.

[0011] Preferably, a pull rope is fixedly connected to the outer side and at the top edge position of the support column. One end of the pull rope is fixedly connected with a sleeve head. The inner wall surface of the sleeve head is movably sleeved on the outer surface of one end of the compression-resistant support rod.

[0012] Preferably, a warning board is fixedly connected to the outer surface of the sleeve. A motor is fixedly installed on the outer surface of the top of the support column and at the bottom edge position of the sleeve. The outer surface of the output end of the motor is movably lapped on the bottom surface of the sleeve.

[0013] Preferably, an empty groove is formed on the outer surface of the inner liner limiting column. A second elastic wire is fixedly connected to the inner wall surface of the empty groove.

[0014] Preferably, a semi-circular convex head is fixedly connected to one end of the second elastic wire. The outer surface of the semi-circular convex head is slidably sleeved on the inner wall surface of the empty groove.

[0015] Preferably, a limiting strip is fixedly connected to the inner side wall surface of the housing, and a fitting groove is formed on the outer surface of the docking concave head and the docking socket head, and the inner side wall surface of the fitting groove is movably sleeved on the outer surface of the limiting strip.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. For a temporary warning support for water conservancy project planning and construction according to the present invention, when the support column moves to a suitable position, the compression-resistant support rod is pulled outwards so that the swing support arm is straightened under the pull of the compression-resistant support rod. When the swing support arm swings, the docking concave head slides on the outer surface of the inner bladder limiting column. As the inner bladder limiting column and the docking concave head continuously turn, the semi-circular convex head on the outer surface of the inner bladder limiting column abuts against the inner side wall surface of the docking groove. At this time, with the assistance of the second elastic wire to elastically push the semi-circular convex head, the semi-circular convex head is firmly positioned on the inner side wall surface of the docking groove. At this time, the docking concave head and the docking socket head are staggered and docked due to the semi-circular convex head, thereby increasing the frictional force and anti-shake force between the docking socket head and the docking concave head, and further forming a whole between the two swing support arms, increasing the compression-resistant support force of the swing support arm;

[0018] 2. For a temporary warning support for water conservancy project planning and construction according to the present invention, after the swing support arm is straightened, it will push the compression-resistant support rod at one end of the swing support arm, and make the surface of the compression-resistant support rod fit on the ground. The contact area with the ground is increased by the extension panel on the outer surface of the compression-resistant support rod. By using the position of the extension panel at the farther end of the compression-resistant support rod, the contact range between the support column and the ground is increased, thereby increasing the anti-shake force of the support column. At this time, a triangle is formed between the support column, the swing support arm and the compression-resistant support rod, and by using the stable state of the triangle, the anti-pressure and compression resistance between the support column and the compression-resistant support rod are increased;

[0019] When the support column is in a state of being retracted, the support column is moved back and forth, and the support column is moved back and forth, so that ... so that the support column is moved back and forth, and the support column is moved back and forth, so that the support column is moved back and forth, so that the support column is moved back and forth, and the support column is moved back and forth, so that the support column is moved back and forth, so that the support column is moved back and forth, so that the support column is moved back and forth, so that the support column is moved back and forth, so that the support column is moved back and forth, so that the support column is moved back and forth, so that the support column is moved back and forth, so that the support column is moved back and forth, so that the support column is moved back and forth, BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0030] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0031] As Figures 1 to 8 shown, a temporary warning bracket for water conservancy project planning and construction according to an embodiment of the present invention includes a support column 11 and a sleeve 12 movably sleeved on the top end of the support column 11, and a swing support arm 13 swingably sleeved on the outer surface of the support column 11. Two groups of housings 131 are fixedly connected to the outer surface of the swing support arm 13 and at the two edge positions in the middle. The first elastic wire 132 is fixedly connected to the inner wall surface of the two groups of housings 131. One end of the first elastic wire 132 is fixedly connected to a docking socket head 134 and a docking concave head 135 movably sleeved on the inner wall surface of the housing 131. One end of the docking socket head 134 is movably sleeved on the outer surface of the docking concave head 135. A docking groove a5 is formed on the inner wall surface of the docking concave head 135. An inner liner limiting post a1 is provided on the outer surface of the docking socket head 134 and at the middle position. A semi-circular convex head a4 is provided on the outer surface of the inner liner limiting post a1 and at the middle position. The outer surface of the semi-circular convex head a4 is movably sleeved on the outer surface of the docking groove a5. A limiting strip 133 is fixedly connected to the inner wall surface of the housing 131. Fitting grooves 136 are formed on the outer surfaces of the docking concave head 135 and the docking socket head 134. The inner wall surface of the fitting groove 136 is movably sleeved on the outer surface of the limiting strip 133.

[0032] When the support column 11 moves to a suitable position, the socket 113 at one end of the tension rope 112 is taken off from the top of the compression-resistant support rod 116. At this time, the compression-resistant support rod 116 is pulled outward, so that the swing support arm 13 is straightened under the pull of the compression-resistant support rod 116. When the swing support arm 13 swings, the docking concave head 135 slides on the outer surface of the inner liner limit post a1. As the inner liner limit post a1 and the docking concave head 135 continuously flip, the semi-circular convex head a4 on the outer surface of the inner liner limit post a1 is docked to the inner wall surface of the docking groove a5. At this time, with the cooperation of the second elastic wire a3, the semi-circular convex head a4 is elastically pushed, so that the semi-circular convex head a4 is firmly positioned on the inner wall surface of the docking groove a5. At this time, an interlaced docking will occur between the docking concave head 135 and the docking socket 134 due to the semi-circular convex head a4, thereby increasing the friction and anti-vibration force between the docking socket 134 and the docking concave head 135, and then forming an integral body between the two swing support arms 13, and increasing the effect of the compression-resistant support force of the swing support arm 13.

[0033] As Figures 1 to 5 shown, an inlaid groove 111 is formed on the outer surface of the support column 11 and at the bottom edge position. One end of the swing support arm 13 is movably sleeved on the top inner wall surface of the inlaid groove 111. A support pad 115 is fixedly connected to the bottom surface of the support column 11. A compression-resistant support rod 116 is swingably connected to the outer surface of the bottom of the support column 11 and at the top edge position of the support pad 115. The other end of the swing support arm 13 is movably sleeved on the top surface of the compression-resistant support rod 116. Expansion panels 117 are fixedly connected to both side surfaces of the other end of the compression-resistant support rod 116.

[0034] After the swing support arm 13 is straightened, it will push the compression-resistant support rod 116 at one end of the swing support arm 13, and make the surface of the compression-resistant support rod 116 fit on the ground. The contact area with the ground is increased through the expansion panel 117 on the outer surface of the compression-resistant support rod 116. By using the position of the expansion panel 117 at the farther end of the compression-resistant support rod 116, the contact range between the support column 11 and the ground is increased, thereby increasing the anti-vibration force of the support column 11. At this time, a triangle is formed among the support column 11, the swing support arm 13 and the compression-resistant support rod 116, and by using the stable state of the triangle, the anti-pressure and compression resistance effects between the support column 11 and the compression-resistant support rod 116 are increased.

[0035] As Figure 1 - Figure 4 and Figures 6 to 8As shown, a resilient wire 114 is fixedly connected to the outer surface of the support column 11, one end of the resilient wire 114 is arranged at the bottom edge of the sunken groove 111, and the other end of the resilient wire 114 is fixedly connected to the top surface of the compression support rod 116. A tension rope 112 is fixedly connected to the outer side of the support column 11 and located at the top edge. One end of the tension rope 112 is fixedly connected to a sleeve 113. The inner wall surface of the sleeve 113 is movably sleeved on the outer surface of one end of the compression support rod 116. The outer side of the sleeve 12 A warning plate 121 is fixedly connected to the surface, a motor 122 is fixedly installed on the top outer surface of the support column 11 and located at the bottom edge of the sleeve 12, the outer surface of the output end of the motor 122 is movably overlapped on the bottom surface of the sleeve 12, and a hollow groove a2 is provided on the outer surface of the inner tank limiting column a1, an elastic wire a3 is fixedly connected to the inner wall of the hollow groove a2, a semicircular boss a4 is fixedly connected to one end of the elastic wire a3, and the outer surface of the semicircular boss a4 is slidably sleeved on the inner wall of the hollow groove a2.

[0036] When the support column 11 needs to be recovered, it is only necessary to use the foot to lightly step on the bent joint of the swing support arm 13. When the docking concave head 135 and the docking sleeve 134 are overturned and bent due to extrusion, the external extrusion force will squeeze the semicircular convex head a4 back into the interior of the empty groove a2. When there is no interlacing force and friction between the inner liner limiting column a1 and the docking concave head 135, the docking concave head 135 and the docking sleeve 134 can slide and bend quickly, so that the swing support arm 13 is no longer in an integral state, and then Through the rebound of the rebound wire 114, the connection between the compression support rod 116 and the support column 11 is turned over as the supporting point, and the compression support rod 116 is erected and tilted, and the bent swing support arm 13 will retract into the inside of the sunken groove 111. At this time, the sleeve 113 on one end of the tension rope 112 is sleeved on the top of the compression support rod 116, and the position of the compression support rod 116 is pulled and supported. The retracted compression support rod 116 can effectively reduce the contact area and fitting range with the outside world.

[0037] Working principle: When the support column 11 is moved to a suitable position, the sleeve 113 at one end of the tension rope 112 is taken off from the top of the compression-resistant support rod 116. At this time, the compression-resistant support rod 116 is pulled outward, so that the swing support arm 13 is straightened under the pull of the compression-resistant support rod 116. When the swing support arm 13 swings, the docking concave head 135 slides on the outer surface of the inner liner limit post a1. As the inner liner limit post a1 and the docking concave head 135 keep flipping, the semi-circular convex head a4 on the outer surface of the inner liner limit post a1 is docked to the inner wall surface of the docking groove a5. At this time, with the help of the second elastic wire a3 to elastically push the semi-circular convex head a4, the semi-circular convex head a4 is firmly positioned on the inner wall surface of the docking groove a5. At this time, an interlaced docking will occur between the docking concave head 135 and the docking sleeve 134 due to the semi-circular convex head a4, thereby increasing the friction and anti-shake force between the docking sleeve 134 and the docking concave head 135, and further forming a whole between the two swing support arms 13, increasing the effect of the anti-compression support force of the swing support arm 13;

[0038] After the swing support arm 13 is straightened, it will push the compression-resistant support rod 116 at one end of the swing support arm 13, and make the surface of the compression-resistant support rod 116 fit on the ground. The contact area with the ground is increased through the expansion panel 117 on the outer surface of the compression-resistant support rod 116. Then, by using the position of the expansion panel 117 at the farther end of the compression-resistant support rod 116, the contact range between the support column 11 and the ground is increased, thereby increasing the anti-shake force of the support column 11. At this time, a triangle is formed among the support column 11, the swing support arm 13 and the compression-resistant support rod 116, and by using the stable state of the triangle, the effect of increasing the anti-pressure and anti-compressibility between the support column 11 and the compression-resistant support rod 116 is achieved;

[0039] When the support column 11 needs to be recovered, it is only necessary to use the foot to lightly step on the bent joint of the swing support arm 13. When the docking concave head 135 and the docking sleeve head 134 are overturned and bent due to extrusion, the external extrusion force will squeeze the semicircular convex head a4 back into the interior of the empty groove a2. When there is no interlacing force and friction between the inner liner limit column a1 and the docking concave head 135, the docking concave head 135 and the docking sleeve head 134 can slide and bend quickly, so that the swing support arm 13 is no longer in an integral state, and then the compression support is made to bend under the rebound of the rebound wire 114. The connection between the rod 116 and the support column 11 is flipped as the support point, and the compression support rod 116 is erected and tilted, and the bent swing support arm 13 will retract into the interior of the sunken groove 111. At this time, the sleeve 113 on one end of the tension rope 112 is sleeved on the top of the compression support rod 116, and the position of the compression support rod 116 is pulled and supported. The retracted compression support rod 116 can effectively reduce the contact area and fitting range with the outside world, and avoid the compression support rod 116 from expanding again during transportation.
