Description
Technical Field
[0001] The utility model belongs to the technical field of construction equipment, and particularly relates to an assembled warning fence for construction sites. Background Technique
[0002] During the construction of a construction site, according to the construction requirements of the site, it is necessary to install a surrounding isolation fence to prevent idle personnel from accidentally entering the construction site and causing safety accidents. Therefore, a construction warning fence is essential.
[0003] Currently, there are warning fences on the market that can be directly placed on the ground. They are light in weight and relatively easy to move over long or short distances. However, to ensure that such warning fences will not be blown down by the wind, usually several bolts that can be driven into the ground are inserted at the bottom of the upright posts. This method not only damages the ground, but the work of driving in the bolts is also rather troublesome. In addition, there are warning fences with built-in counterweights on the market. Such warning fences can maintain good wind resistance without the need to fix the bolts to the ground. However, the warning fences with built-in counterweights are relatively heavy, and it is rather troublesome to move them over short distances or transport them over long distances. Summary of the Invention
[0004] The purpose of the utility model is to solve the problems existing in the prior art, and provides an assembled warning fence for construction sites, which combines the advantages of warning fences with counterweights and warning fences without counterweights, has good wind resistance, and is relatively simple to disassemble, assemble and transport.
[0005] To achieve the above purpose, the utility model is realized by adopting the following technical solutions: An assembled warning fence for construction sites includes a warning fence. Connectors are provided at both ends of the warning fence. There are not less than two plug-in parts at the bottom end of the warning fence. The plug-in part includes a plug board connected to the bottom end of the warning fence. A groove is formed on one side of the plug board. Rack teeth are evenly arranged on the inner wall of the groove. The bottom end of the warning fence is connected with a counterweight seat through the plug-in part. A locking groove is formed on one side of the counterweight seat along the length direction. A locking part is arranged in the locking groove. The locking part includes a shaft rod. A gear meshing with the rack teeth is arranged on the surface of the shaft rod. A ratchet wheel is arranged on the surface of the shaft rod. An elastic torsion part is arranged on the bottom wall of the locking groove. A pawl adapted to the ratchet wheel and rotatably connected to the bottom wall of the locking groove is arranged on the elastic torsion part. There are not less than two universal wheels on the counterweight seat along the length direction and on the same side as the locking groove.
[0006] Through the above technical means, the warning column can be directly inserted into the counterweight base through a plug. After insertion, the plug is automatically locked, and the connection between the warning column and the counterweight base can be completed, enabling the warning column to have a good wind resistance effect. When disassembling, simply step on the pawl in the locking member to unlock the plug, and then the warning column can be withdrawn. Both installation and disassembly are very simple. In addition, when moving, if it is a short-distance relocation, just flip the warning column, then the counterweight base will also flip, making the universal wheels touch the ground, and it can be easily dragged for short-distance relocation. If it is a long-distance transportation, the warning column and the counterweight base can be disassembled and transported in batches, which is also relatively easy for construction workers.
[0007] Further, the warning column includes a circular tube frame and a guardrail net arranged inside the circular tube frame, and warning signs are provided on both sides of the guardrail net.
[0008] Using a guardrail net to fill the inside of the circular tube frame reduces the overall weight of the warning column, making it convenient to carry. At the same time, warning signs are set on both sides of the guardrail net, which can not only warn pedestrians but also construction workers.
[0009] Further, the connecting member includes a connecting hook arranged on one side of the warning column and a communicating cylinder arranged on the other side of the warning column, and the connecting hook and the communicating cylinder are mutually adapted.
[0010] Through the above components, multiple warning columns can be easily spliced together.
[0011] Further, a chamfered cut is provided at the bottom end of the insertion plate facing the groove side, and the groove faces the locking groove.
[0012] Through the above technical features, the rack in the insertion plate can be more easily engaged with the gear.
[0013] Further, a slot adapted to the plug is provided at the top of the counterweight base, and the slot communicates with the locking groove.
[0014] Further, a chamfered cut is provided on the side of the counterweight base facing the universal wheel and below the universal wheel.
[0015] A chamfered cut is provided at the edge on one side of the counterweight base and below the universal wheel, making it easier for workers to flip the counterweight base and make the universal wheels touch the ground.
[0016] Further, both ends of the shaft rod are rotatably installed on the inner walls of both sides of the locking groove.
[0017] The gear drives the shaft rod to rotate, and then drives the ratchet to rotate.
[0018] Further, a bent portion is provided on the side of the pawl close to the ratchet, and the bent portion is placed on the surface of the ratchet.
[0019] With the above characteristics, when the ratchet rotates counterclockwise, the pawl can slide smoothly on the ratchet.
[0020] Furthermore, a stepping portion is provided on the side of the pawl away from the bent portion. The included angle between the stepping portion and the main body of the pawl is an obtuse angle. The pawl is rotatably connected to the inner bottom wall of the anti-lock groove through a bushing.
[0021] By setting the stepping portion, when the worker disassembles the warning bar from the counterweight seat, he only needs to step on the stepping portion to make the bent portion of the pawl tilt up, thereby releasing the restriction on the anti-backward rotation of the ratchet, and then he can easily pull out the warning bar from the counterweight seat.
[0022] Furthermore, the elastic torsion member is any one of a "V"-shaped spring leaf and a torsion spring.
[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. The warning bar can be directly inserted into the counterweight seat through the plug-in part. After insertion, the plug-in part is automatically locked, and the connection between the warning bar and the counterweight seat can be completed, enabling the warning bar to have good wind resistance; 2. During disassembly, only by stepping on the pawl in the anti-lock member can the locking of the plug-in part be released, and then the warning bar can be pulled out. Both installation and disassembly are very simple; 3. If it is necessary to move the position for a short distance, only need to flip the warning bar, and then flip the counterweight seat to make the universal wheels touch the ground, and then it can be easily dragged for short-distance position movement. If it is for long-distance transportation, the warning bar and the counterweight seat can be disassembled and transported in batches, which is also relatively easy for construction workers; 4. Chamfered cuts are made on the edge of the counterweight seat on one side and below the universal wheels, making it easier for the worker to flip the counterweight seat to make the universal wheels touch the ground.

Specific embodiments
[0033] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.
[0034] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0035] As Figure 1 shown in -8, the specific solution of the embodiment is as follows: An assembled warning column for a construction site includes a warning column 1. Connecting members 2 are provided at both ends of the warning column 1. At least two plug-in members 3 are provided at the bottom end of the warning column 1. The plug-in member 3 includes an insertion plate 31 connected to the bottom end of the warning column 1. A groove 311 is formed on one side of the insertion plate 31. Rack teeth 32 are evenly provided on the inner wall of the groove 311. The bottom end of the warning column 1 is connected to a counterweight seat 4 through the plug-in member 3. A locking groove 6 is formed on one side of the counterweight seat 4 along the length direction. A locking member 7 is provided in the locking groove 6. The locking member 7 includes a shaft rod 71. A gear 72 meshing with the rack teeth 32 is provided on the surface of the shaft rod 71. A ratchet wheel 73 is provided on the surface of the shaft rod 71. An elastic torsion member 74 is provided on the bottom wall of the locking groove 6. A ratchet pawl 75 adapted to the ratchet wheel 73 and rotatably connected to the bottom wall of the locking groove 6 is provided on the elastic torsion member 74. At least two universal wheels 8 are provided on the counterweight seat 4 along the length direction and on the same side as the locking groove 6.
[0036] During use, the plug-in 3 is directly inserted into the counterweight base 4. After insertion, the plug-in 3 is automatically locked, and the connection between the warning rail 1 and the counterweight base 4 is completed. When disassembling, simply step on the pawl 75 in the unlocking member 7 to release the lock on the plug-in 3, and then the warning rail 1 can be withdrawn. Both the assembly and disassembly are very simple. In addition, when moving, just flip the warning rail 1, and then flip the counterweight base 4 to make the universal wheels 8 touch the ground, and the entire device can be easily dragged, which is also relatively easy for construction workers.
[0037] As Figure 2 shown, the warning rail 1 includes a round tube frame and a guardrail net arranged inside the round tube frame. Warning signs are provided on both sides of the guardrail net. Using the guardrail net to fill the inside of the round tube frame reduces the overall weight of the warning rail 1, facilitating handling. At the same time, warning signs are set on both sides of the guardrail net, which can not only warn pedestrians but also warn construction workers.
[0038] As Figure 1-2 shown, the connecting member 2 includes a connecting hook 21 arranged on one side of the warning rail 1 and a communicating cylinder 22 arranged on the other side of the warning rail 1. The connecting hook 21 and the communicating cylinder 22 are mutually adapted; multiple warning rails 1 can be easily spliced together.
[0039] As Figure 3 shown, a chamfered cut is provided at the bottom of the plug plate 31 on the side facing the groove 311, and the groove 311 faces the locking groove 6; this allows the rack 32 in the plug plate 31 to more easily engage with the gear 72.
[0040] As Figure 4 、 Figure 6 shown, a slot 5 adapted to the plug-in 3 is provided at the top of the counterweight base 4, and the slot 5 communicates with the locking groove 6.
[0041] A chamfered cut is provided on one side of the counterweight base 4 facing the universal wheel 8 and below the universal wheel 8; a chamfered cut is provided on the edge of one side of the counterweight base 4 and below the universal wheel 8, making it easier for workers to flip the counterweight base 4 to make the universal wheels 8 touch the ground.
[0042] As Figure 5 shown, both ends of the shaft rod 71 are rotatably installed on the inner walls of both sides of the locking groove 6. The gear 72 drives the shaft rod 71 to rotate, and then drives the ratchet wheel 73 to rotate.
[0043] As Figure 7 、 Figure 8 shown, the side of the teeth on the surface of the ratchet wheel 73 on the counterclockwise side is an arc surface, and a bent portion is provided on the side of the pawl 75 close to the ratchet wheel 73. The bent portion is placed on the surface of the ratchet wheel 73, enabling the pawl 75 to slide smoothly on the ratchet wheel 73 when the ratchet wheel 73 rotates counterclockwise.
[0044] A treading portion is provided on the side of the pawl 75 away from the bending portion, and an obtuse angle is formed between the treading portion and the main body of the pawl 75 . The pawl 75 is rotatably connected to the inner bottom wall of the locking groove 6 through a shaft sleeve.
[0045] A treading part is provided, and when a worker removes the prohibiting fence from the counterweight seat 4 , he only needs to step on the treading part to make the bent part of the pawl 75 tilt up, thereby loosening the restriction on the ratchet 73 to prevent reverse rotation, and the prohibiting fence can be easily pulled out from the counterweight seat 4 .
[0046] Secondly, the elastic torsion member 74 is any one of a "V"-shaped spring sheet and a torsion spring. Through the action of the "V"-shaped spring sheet or the torsion spring, when there is no external force pressing the pedal portion, the bent portion will always rest on the ratchet 73.
[0047] The working principle of the above embodiment is as follows: a worker inserts the plug-in 3 directly into the slot 5 on the counterweight seat 4. After insertion, the plug-in 3 contacts the gear 72. As the plug-in 3 continues to move downward, the gear 72 rotates on the rack 32. During the rotation of the gear 72, the ratchet 73 rotates synchronously driven by the shaft 71 until the plug-in 3 is inserted into the bottom wall of the slot 5. After the ratchet 73 stops rotating, the bent portion of the pawl 75 is naturally stuck between two adjacent teeth on the ratchet 73, making it impossible for the ratchet 73 to reverse, thereby locking the plug-in 3 and completing the connection between the warning bar 1 and the counterweight seat 4. When disassembling, step on the pawl 75 in the locking member 7 to make the bent portion of the pawl 75 tilt upward and disengage from the ratchet 73, so as to release the lock on the plug-in 3 and then the warning bar 1 can be pulled out; when moving, flip the warning bar 1, so that the counterweight seat 4 flips, until the universal wheel 8 is grounded, and the entire device can be easily dragged.
[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
