Description

Technical Field

[0001] This utility model relates to the field of construction, and more specifically to a construction safety railing that is easy to install. Background Technology

[0002] Construction safety railings are essential safety protection facilities on construction sites. Made of sturdy and durable materials, they effectively isolate the construction area from the outside world, prevent unauthorized personnel from entering dangerous areas, and reduce the risk of accidental falls or being struck by objects. Their eye-catching colors and markings serve as warnings, providing a reliable safety barrier for construction workers and passersby.

[0003] Common construction safety railings are usually large in size and need to be combined according to the actual isolation area requirements, which makes it inconvenient for operators to move the safety railings during installation, thus reducing the installation efficiency when assembling multiple safety railings. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a construction safety guardrail that is easy to install, which is convenient for transportation and helps to improve the installation efficiency of the guardrail.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A construction safety railing that is easy to install has the following structural features: The bottom of the guardrail body is equipped with at least one pair of caster assemblies, and the two vertical sides serve as splicing sides between adjacent guardrails. One side has at least one set of upper ear plates, and the other side has at least one set of lower ear plates. The caster assembly includes casters and a locking component. The locking component is used to lock or unlock the caster axle. The relative position between the caster and the guardrail body is adjustable in the height direction via the locking component. When the caster axle is locked by the locking component, the guardrail body is suspended above the ground, and the entire guardrail is supported on the ground by the casters in a rolling manner. After the caster axle is unlocked by the locking component, the guardrail body can fall relative to the casters by its own weight until the bottom surface of the guardrail body contacts the ground, and the guardrail body can be fixed to the ground by bolts. The falling height of the guardrail body is A. When adjacent guardrails are spliced ​​together, the axles of all casters in one set of guardrails are locked, and the axles of all casters in the other set of guardrails are unlocked. The height difference B between the two guardrail bodies matches the drop height A of the guardrail bodies. One set of guardrails has its side with the upper ear plate facing the side with the lower ear plate of the other set of guardrails. The upper and lower ear plates are staggered along the height direction. Adjacent upper and lower ear plates form a set of connectors. The upper and lower ear plates of each set of connectors are assembled by a connecting shaft.

[0006] The structural features of this utility model also lie in: In the caster assembly: The locking member includes a locking frame, a connecting rod assembly, and a locking assembly; the locking frame is rotatably connected to the bottom of the guardrail main body through a rotating shaft fixedly connected to the top of the frame. The frame body of the locking frame is in a "C" shape with an open bottom and covers the periphery of the caster. The caster is rotatably sleeved on the wheel axle coaxially. The wheel axle passes through the guiding holes on both sides of the locking frame, is in sliding fit with the guiding holes, and both ends extend outside the locking frame. The locking assembly is used to lock or unlock the wheel axle. When the wheel axle is fastened to the locking frame through the locking assembly, it is locked. After the wheel axle is unlocked through the locking assembly, it can be displaced relative to the locking frame. The relative displacement is a vertical linear displacement guided by the guiding holes through the sliding fit between the wheel axle and the guiding holes. The relative displacement includes the downward fall of the locking frame and the guardrail main body together relative to the wheel axle by their own weight, and also includes the vertical sliding of the wheel axle along the guiding holes under the drive of an external force to pull the connecting rod assembly in the unlocked state.

[0007] In the caster assembly: The connecting rod assembly includes an adjusting plate and a connecting rod; the locking assembly includes a locking block with a threaded hole, a perforation reserved at the outer end of the locking frame, and a locking bolt; the adjusting plate is in the shape of a triangular plate. One corner of the adjusting plate is hinged to the locking frame, another corner is hinged to the upper part of the connecting rod, and the remaining corner is the stress end. The end of the wheel axle extending outside the locking frame on the corresponding side rotatably passes through the lower part of the connecting rod. Each hinge shaft is parallel to the wheel axle; the end of the wheel axle is fixedly connected to the locking block, and the locking bolt passing through the perforation can be threadedly assembled with the locking block at the threaded hole for locking the wheel axle.

[0008] The lower ear plate has a vertically penetrating connecting hole, and the bottom end of the upper ear plate has the connecting shaft vertically downward. The number of upper ear plates on each guardrail is the same as the number of lower ear plates. The upper ear plates and the lower ear plates are staggered in the height direction. Among the upper ear plates and the lower ear plates adjacent in height position, the upper ear plates and the connecting shafts they carry are higher than the lower ear plates; when adjacent guardrails are spliced, the guardrail main body of the group of guardrails with the casters locked faces the side of the guardrail main body of the other group of guardrails with the casters unlocked with the upper ear plates. The upper ear plates and the lower ear plates adjacent in height position are a set of connecting parts. The connecting shaft of the upper ear plate of each set of connecting parts passes through the connecting hole of the lower ear plate, and each set of connecting parts jointly realizes the splicing of adjacent guardrails.

[0009] The bottom end of the guardrail main body has a mounting plate and a foot pad, and is supported on the ground through the foot pad. The mounting plate is fixed to the ground through bolts at the mounting threaded holes reserved on the plate body.

[0010] The guardrail main body has a warning mounting plate, and the warning mounting plate is used to mount warning signs. The plate body has multiple mounting holes reserved for assembling with the warning signs.

[0011] Compared with the prior art, the beneficial effects of the present utility model are reflected in: The caster assembly of this utility model occupies less space than the overall structure and has little impact on the overall size of the guardrail. The caster assembly facilitates the transportation of the guardrail and can also be used to complete the splicing of adjacent guardrails. The caster axle of the caster assembly can be locked or unlocked by the locking component, so that the main body of the guardrail can be raised above the ground or lowered to the ground. Based on this, two adjacent guardrails can be easily spliced ​​by using two guardrail bodies at different heights. During splicing, the upper and lower ear plates can be used to achieve quick assembly. Attached Figure Description

The caster assembly 2 includes a caster 21 and a locking member. The locking member is used to lock or unlock the axle 22 of the caster 21. The relative position between the caster 21 and the guardrail main body 1 is adjustable in the height direction by the locking member. When the axle 22 of the caster 21 is locked by the locking member, the guardrail main body 1 is suspended above the ground, and the whole guardrail is supported on the ground rollably by the casters 21. After the axle 22 of the caster 21 is unlocked by the locking member, the guardrail main body 1 can fall relative to the caster 21 by its own weight until the bottom surface of the guardrail main body 1 contacts the ground, and the guardrail main body 1 can be fixed to the ground by bolts. The falling height of the guardrail main body 1 is A. When adjacent guardrails are spliced, the axles 22 of the casters 21 of one group of guardrails are locked, and the axles 22 of the casters 21 of the other group of guardrails are unlocked. The difference B in the height positions between the two guardrail main bodies 1 matches the falling height A of the guardrail main body 1. One group of guardrails has a side with an upper ear plate 11 opposite to the side of the other group of guardrails with a lower ear plate 12. The positions of the upper ear plate 11 and the lower ear plate 12 are staggered in the height direction. Taking the adjacent upper ear plate 11 and lower ear plate 12 as a set of connecting parts, the upper ear plate 11 and the lower ear plate 12 of each set of connecting parts are assembled through a connecting shaft 111.

[0016] In the specific implementation of the conveniently installed construction safety guardrail of this embodiment, the corresponding structural settings also include: In the caster assembly 2: The locking member includes a locking frame 24, a connecting rod assembly, and a locking assembly. The locking frame 24 is rotatably connected to the bottom of the guardrail main body 1 through a rotating shaft 23 fixedly connected to the top of the frame. The frame body of the locking frame 24 is in a "C" shape with an open bottom and covers the periphery of the caster 21. The caster 21 is rotatably sleeved on the axle 22 coaxially. The axle 22 passes through the guiding holes 241 on both sides of the locking frame 24, is in sliding fit with the guiding holes 241, and both ends extend outside the locking frame 24. The locking assembly is used to lock or unlock the axle 22. When the axle 22 is fastened to the locking frame 24 through the locking assembly, it is locked. After the axle 22 is unlocked through the locking assembly, it can be displaced relative to the locking frame 24. The relative displacement is a vertical linear displacement guided by the guiding holes 241 through the sliding fit between the axle 22 and the guiding holes 241. The relative displacement includes the falling of the locking frame 24 and the guardrail main body 1 together relative to the axle 22 by their own weight, and also includes the vertical sliding of the axle 22 along the guiding holes 241 under the drive of an external force to pull the connecting rod assembly to unlock the axle 22.

[0017] There are two sets of caster assemblies 2. In each set of caster assemblies 2: The linkage assembly includes an adjusting plate 25 and a connecting rod 26; the locking assembly includes a locking block 27 with a screw hole, a through hole 28 reserved at the outer end of the locking frame 24, and a locking bolt 29; the adjusting plate 25 is triangular in shape, one corner of the adjusting plate 25 is hinged to the locking frame 24, another corner is hinged to the upper part of the connecting rod 26, and the remaining corner serves as the force-bearing end; the end of the wheel axle 22 extending to the outside of the locking frame 24 is rotatably inserted through the lower part of the connecting rod 26, and each hinge axis is parallel to the wheel axle 22; the end of the wheel axle 22 is fixedly connected to the locking block 27, and the locking bolt 29 through the through hole 28 and the locking block 27 can be threaded together at the screw hole for locking the wheel axle 22.

[0018] The lower ear plate 12 has a vertically penetrating connecting hole 121, and the bottom end of the upper ear plate 11 has a vertically downward connecting shaft 111. The number of upper ear plates 11 on each set of guardrails is the same as the number of lower ear plates 12. The upper ear plates 11 and lower ear plates 12 are staggered along the height direction. Among the upper ear plates 11 and lower ear plates 12 that are adjacent in height, the upper ear plate 11 and its connecting shaft 111 are higher than the lower ear plate 12. When splicing adjacent guardrails, the guardrail body 1 of the set of guardrails where each caster 21 is locked faces the side of the guardrail body 1 with the lower ear plate 12 with the side of the guardrail body 1 of the other set of guardrails where each caster 21 is unlocked. The upper ear plates 11 and lower ear plates 12 that are adjacent in height form a set of connectors. The connecting shaft 111 of the upper ear plate 11 of each set of connectors passes through the connecting hole 121 of the lower ear plate 12. Each set of connectors together realizes the splicing between adjacent guardrails.

[0019] The bottom of the guardrail body 1 is equipped with a mounting plate 13 and rubber foot pads 14. The foot pads 14 support the ground, and the mounting plate 13 is fixed to the ground with bolts at the pre-drilled mounting thread holes on the plate body.

Each fixing clip 16 has a fixing screw hole, and the dustproof cloth can be further tightened by bolts at the fixing screw hole.

[0022] The construction safety guardrails in this embodiment are easy to install, both in terms of transportation and splicing between guardrails. The operation method can be found as follows: I. Transfer Initially, the axle 22 of the caster 21 is locked, and the caster 21 can roll and support itself on the ground. The main body of the guardrail 1 is suspended in the air. The entire guardrail can be moved by the caster 21, thus achieving convenient transportation. II. Splicing When adjacent guardrails are spliced ​​together, the axle 22 of the caster 21 of one set of guardrails is locked and the main body 1 of the guardrail is suspended. This set of guardrails is referred to as guardrail A. The other set of guardrails is referred to as guardrail B. The side of guardrail A with the lower ear plate 12 is aligned with the side of guardrail B with the upper ear plate 11. The upper ear plate 11 and the lower ear plate 12 are adjacent in height. The upper ear plate 11 is located above the lower ear plate 12, and the connecting shaft 111 of the upper ear plate 11 is higher than the lower ear plate 12 and directly opposite the connecting hole 121 on the lower ear plate 12. Next, unlock the axle 22 of the caster 21 of guardrail B. The unlocking method is as follows: loosen the locking bolt 29 of the locking component and remove it, so that the axle 22 of the caster 21 and the locking frame 24 can be moved relative to each other. The locking frame 24 and the guardrail body 1 on it will fall to the foot pad 14 at the bottom of the guardrail body 1 under the guidance of gravity and through the sliding cooperation of the axle 22 and the guide hole 241, and be supported on the ground. Then, the mounting plate 13 on the guardrail body 1 is fastened to the ground with bolts. As guardrail B falls, the connecting shaft 111 of the upper ear plate 11 of guardrail B will fall into the connecting hole 121 of the lower ear plate 12 of guardrail A, thereby achieving splicing between adjacent guardrails through the insertion of multiple pairs of upper ear plates 11 and lower ear plates 12. III. Relocking of caster 21 and axle 22 The linkage assembly and locking assembly in the caster assembly 2 are required; apply external force to the adjusting plate 25 of the linkage assembly, move the adjusting plate 25, and use the adjusting plate 25 to drive the wheel axle 22 to slide down along the guide hole 241 through the linkage until the caster 21 is supported on the ground again, raising the guardrail body 1 to be suspended again. Then, use the locking bolt 29 to pass through the through hole 28 and lock it with the locking block 27 to achieve the relocking of the wheel axle 22 of the caster 21.
