Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to an electrically operated lifting guardrail for end protection of continuous beams. Background Technology

[0002] In modern civil engineering, continuous beam structures are widely used due to their superior mechanical properties and broad application range. However, certain safety risks exist during the construction of continuous beams, especially at the beam ends. Because the adjacent edges of the beam ends are exposed during construction, falls are prone to occur, posing a threat to the lives of construction workers.

[0003] Most of the protective measures currently available on the market are fixed. While these protective devices can provide a certain level of safety, they require frequent disassembly and installation during construction, making the operation cumbersome, time-consuming, and labor-intensive. They are also not suitable for rapidly changing construction needs. Furthermore, fixed protective devices have poor adaptability to different construction stages and cannot provide flexible protection solutions. Utility Model Content

[0004] The purpose of this invention is to provide an electrically operated lifting guardrail for the end protection of continuous beams, so as to solve the above-mentioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electric lifting guardrail for end protection of continuous beams, comprising a guardrail, six steel cable lugs fixedly connected to the top of the guardrail, steel wire ropes connected to the multiple steel cable lugs, hooks provided on the steel wire ropes on two adjacent steel cable lugs, and a tensioning mechanism provided between the hooks and the bottom of the guardrail.

[0006] As a further description of the above technical solution: a connecting seat is provided at the top of the hook, the tensioning mechanism includes a winding shaft, the winding shaft is rotatably disposed on one side of the connecting seat, a traction rope is fixedly connected to one end of the winding shaft, one end of the traction rope passes through the bottom of the guardrail and is fixedly connected to a plug, the traction rope is slidably adapted to the bottom of the guardrail, and a one-way rotation component is provided between the winding shaft and the connecting seat.

[0007] As a further description of the above technical solution: the three traction ropes are respectively set on both sides of the guardrail, the traction ropes at both ends are set on the same side of the guardrail, and the traction rope in the middle position is set on the other side of the guardrail.

[0008] As a further description of the above technical solution: the one-way rotation assembly includes a ratchet, which is rotatably mounted on the connecting seat. A locking tongue is provided on the top of the ratchet, which is adapted to the ratchet. A torsion spring is provided between the locking tongue and the connecting seat, and the winding shaft is located on one side of the ratchet.

[0010] As a further description of the above technical solution: the guardrail is provided with multiple protective nets and protective plates.

[0011] This utility model provides an electrically operated lifting guardrail for the end protection of continuous beams. It has the following advantages: This device connects and lifts the guardrail using steel cable lugs and wire ropes. The six steel cable lugs are divided into three groups, with two adjacent lugs forming one group. A hook suspends the wire ropes on the two lugs in the same group, thus lifting the guardrail. When the hook is raised and lowered by a motor, the bottom of the guardrail is prone to swaying during the process. Therefore, this device uses a tensioning mechanism between the hook and the bottom of the guardrail to pull the bottom of the guardrail, preventing swaying and ensuring stability during lifting and lowering driven by the hook.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-5 An electrically operated lifting guardrail for end protection of continuous beams includes a guardrail with six steel cable lugs fixedly connected to its top. Steel wire ropes are connected to each of the steel cable lugs, and hooks are attached to the steel wire ropes on adjacent steel cable lugs. A tensioning mechanism is provided between the hooks and the bottom of the guardrail. This device connects and lifts the guardrail using the steel cable lugs and steel wire ropes. The six steel cable lugs are divided into three groups, with two adjacent lugs forming one group. The hooks suspend the steel wire ropes on the two lugs in the same group, thus lifting the guardrail. When the hooks are raised and lowered by a motor, the bottom of the guardrail is prone to swaying during the process. Therefore, this device uses the tensioning mechanism between the hooks and the bottom of the guardrail to pull the bottom of the guardrail to prevent swaying, thereby ensuring its stability during raising and lowering driven by the hooks.

[0018] As a preferred technical solution in this embodiment, a connecting seat is provided at the top of the hook, and the tensioning mechanism includes a winding shaft. The winding shaft is rotatably disposed on one side of the connecting seat, and a traction rope is fixedly connected to one end of the winding shaft. One end of the traction rope passes through the bottom of the guardrail and is fixedly connected to a plug. The traction rope is slidably adapted to the bottom of the guardrail, and a one-way rotation component is provided between the winding shaft and the connecting seat. During the use of this device, the bottom of the guardrail is restricted by external force through the traction of the traction rope, so that the bottom of the guardrail does not swing during the lifting and lowering process.

[0019] As a preferred technical solution in this embodiment, the three traction ropes are respectively arranged on both sides of the guardrail, with the traction ropes at both ends arranged on the same side of the guardrail and the traction rope in the middle arranged on the other side of the guardrail. When the bottom of the guardrail is limited, the bottom of the guardrail is pulled by the three traction ropes. When the traction ropes are taut, the guardrail will have a tendency to swing in the direction of tightening of the traction ropes. Therefore, the traction ropes are arranged on both sides so that the guardrail is pulled on both sides to avoid swinging.

[0020] As a preferred embodiment, the unidirectional rotation assembly includes a ratchet, which is rotatably mounted on the connecting seat. A locking tongue is provided on the top of the ratchet and is adapted to the ratchet. A torsion spring is provided between the locking tongue and the connecting seat, and the take-up shaft is located on one side of the ratchet. This device uses the rotation of the ratchet to wind the traction rope onto the take-up shaft, thereby tightening the traction rope. The locking tongue ensures that the ratchet rotates in one direction and will not rotate back, causing the traction rope to loosen. The torsion spring ensures that the locking tongue is always close to the ratchet.

[0021] As a preferred technical solution in this embodiment, a connecting block is fixedly connected to the ratchet, and the winding shaft is fixedly connected to the connecting block. The connecting block is provided with a plug hole. During the process of rotating the winding shaft to wind up the traction rope, a long rod can be inserted into the plug hole. The connecting block and the winding shaft can be rotated by the long rod, which saves more effort.

[0022] As a preferred technical solution in this embodiment, the guardrail is provided with multiple protective nets and protective plates; the combination of protective nets and protective plates increases the structural strength of the guardrail while also increasing its shielding ability.

[0023] In the description of this specification, references to terms such as "an embodiment," "example," "specific example," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
