Description

Technical Field

[0001] The invention relates to a safety protection structure for a scaffolding board during construction, and in particular to a horizontal protection device for a scaffolding board. Background Art

[0002] The construction requires that a horizontal protective net should be set up in the gap between the working layer and the main structure. Usually, a gap of 200-400mm needs to be reserved between the inner side poles of the scaffolding and the main structure as an operating space for waterproofing, curtain wall construction and other processes. If the horizontal protective net is laid directly to the main structure in the early stage, it will need to be removed and readjusted during the later waterproofing and curtain wall construction; if the 200-400mm gap is directly retained in the early stage, it will not only fail to meet safety requirements, but also be unsightly. In addition, the horizontal soft net is not convenient to store and place when it is idle. It is generally randomly stacked on the construction site, which will not only increase the loss of the horizontal soft net, but also need to be rearranged when it is used again, which is a waste of manpower and material resources.

[0003] It can be seen that the horizontal protection structure between the current working layer and the main structure still needs to be improved. It should be adjusted and optimized to not only meet the needs of safety protection, but also be able to adjust the protection width in time according to the progress of the construction, and use the external wall construction needs of the construction. At the same time, it can also reasonably store the protection net to avoid the situation of chaotic stacking of the protection net. Therefore, it is necessary to propose a more reasonable technical solution to solve the technical problems existing in the existing technology. Summary of the invention

[0004] In order to overcome at least one of the defects mentioned above, the present invention proposes a horizontal protection device for scaffolding boards. By setting a protection net structure with adjustable length, when different protection lengths are required in the early and later stages of construction, flexible adjustments can be made in time. The device is convenient and flexible to use and easy to store and place, thus ensuring the needs of safety protection.

[0005] In order to achieve the above-mentioned purpose, the protective device disclosed in the present invention can adopt the following technical solutions:

[0006] A horizontal protection device for scaffolding boards comprises two connecting slides for connecting to a scaffold, a fixed mesh roller is arranged at the front end of the connecting slide, and a movable mesh roller is also arranged on the connecting slide, and a protective net is connected between the fixed mesh roller and the movable mesh roller; the movable mesh roller is slidably arranged on the connecting slide and reciprocates along the connecting slide to approach or move away from the fixed mesh roller, and a driving structure for driving the movable mesh roller is arranged on the connecting slide; a locker is arranged on the movable mesh roller, and the locker is used to unlock the movable mesh roller to retract the protective net, or lock the movable mesh roller to tighten the protective net.

[0007] The protective device disclosed above utilizes the movable mesh roller to approach or move away from the fixed mesh roller to adjust the length of the protective distance. The protective net can be tightened by adjusting the movable mesh roller with a lock, thereby ensuring that the protective net can meet the protection needs. A larger protection range can be provided in the early stage of construction, and the required construction gap can be left in the later stage of construction. This improves the convenience of use and reduces the repetitive work of setting up the protective net.

[0008] Furthermore, in the present invention, the structure of the movable net roller is not limited to a single one. Here, an optimization is performed and one feasible option is proposed: the movable net roller includes a roller shaft, and a rotating sleeve on the roller shaft is provided with a roller sleeve for retracting the protective net, and the locking device is used to unlock the roller sleeve or lock the roller sleeve. When such a solution is adopted, the rotating sleeve rotates on the roller shaft, and the protective net is rolled up or unrolled during the rotation process. The length of the protective net can be adjusted according to the actual protection range. After the adjustment is in place, the roller sleeve is locked by the locking device, so that the protection range of the protective net can be adjusted, and at the same time, the protective net is kept taut to provide sufficient protection capability.

[0009] Furthermore, when the movable net roller is unlocked, the rotating sleeve can rotate relative to the roller shaft, thereby realizing the winding and unwinding of the protective net. In order to make the rotating sleeve automatically wind up, the structure of the movable net roller is optimized and the following feasible option is proposed: a reset member is arranged between the roller shaft and the rotating sleeve, and the reset member applies a reset force to the rotating sleeve to retract the protective net. When such a scheme is adopted, the reset member can be an elastic member, such as a spring, a torsion spring, etc. Under normal conditions, the reset member maintains elastic deformation and applies an elastic reset force to the rotating sleeve. When the movable net roller is unlocked, the rotating sleeve is wound up under the action of the reset force.

[0010] Furthermore, the structure of the lock is not limited to a single one. It is optimized here and one of the feasible options is proposed: the lock includes a locking sleeve, which is sleeved on the end of the roller shaft, and the end of the roller shaft is provided with a polygonal columnar section corresponding to the locking sleeve, the inner hole of the locking sleeve is correspondingly polygonal and sleeved on the polygonal columnar section, the locking sleeve slides back and forth along the axial direction of the polygonal columnar section, and the roller shaft is provided with an elastic push piece to push the locking sleeve toward the middle of the roller shaft; a rotating locking structure is provided between the rotating sleeve and the locking sleeve, when the locking sleeve is pushed to fit the rotating sleeve and the rotating locking structure is engaged, the locking sleeve locks the rotating sleeve, and when the locking sleeve leaves the rotating sleeve and the rotating locking structure is released, the rotating sleeve is unlocked. When such a scheme is adopted, the polygonal columnar section cooperates with the locking sleeve to prevent the locking sleeve from circumferential deflection, and only axial displacement can occur; when the locking sleeve moves axially to cooperate with the rotating sleeve, the rotating sleeve is synchronously locked and its circumferential rotation is prevented. When the locking sleeve moves axially and separates from the rotating sleeve, the rotating sleeve can rotate circumferentially.

[0011] Furthermore, in the present invention, the rotating clamping structure can adopt a variety of forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the rotating clamping structure includes a rotating clamping groove and a rotating clamping tooth, and the rotating clamping groove and the rotating clamping tooth are correspondingly arranged on the fitting surface of the locking sleeve and the rotating sleeve. When such a scheme is adopted, the rotating clamping grooves are evenly spaced along the circumference, and the smaller the interval and the more the number of settings, the higher the locking accuracy.

[0012] Furthermore, in the present invention, the elastic push member includes a spring. When such a solution is adopted, the spring can be coaxially arranged on the roller shaft, one end of which is connected and fixed to the end of the roller shaft, and the other end is pressed against the locking sleeve, and when the locking sleeve compresses the spring and moves toward the end of the roller shaft, the locking sleeve is unlocked from the rotating sleeve.

[0013] Furthermore, when the protective length of the protective net needs to be adjusted, the effect is achieved by adjusting the distance between the fixed net roller and the movable net roller. The movable net roller's moving structure can be achieved in a variety of ways. Here, optimization is performed and one of the feasible options is proposed: a linear slide is provided on the connecting slide, a slider is provided in the linear slide, and the sliders of adjacent connecting slides are fixedly connected by a connecting frame; a threaded rod is provided in the linear slide to cooperate with the slider and drive the slider to move back and forth along the linear slide, and the rear end of the threaded rod protrudes from the rear end of the connecting slide and is provided with a rotating head. When such a scheme is adopted, the slider moves along the linear slide by rotating the threaded rod, thereby driving the movable net roller to move back and forth. Under this structure, the distance between the movable net roller and the fixed net roller can be adjusted to achieve the adjustment of the length of the protective net. At the same time, the characteristics of the threaded fit can be used to maintain the stability of the distance and avoid slippage.

[0014] Furthermore, in order to improve the convenience of adjusting the position of the movable mesh roller, the structure of the adjacent movable mesh rollers is optimized, and one feasible option is proposed: the front end or rear end of the threaded rod is also provided with a synchronous gear, and the synchronous gears of the adjacent threaded rods are connected and matched through a synchronous chain to make the adjacent threaded rods rotate synchronously. When such a solution is adopted, the synchronous gear rotates synchronously with the threaded rod, and the adjacent threaded rods can rotate synchronously after being connected by the synchronous chain, thereby maintaining the synchronous movement of the two ends of the movable mesh roller, and improving the convenience of operation.

[0015] Furthermore, in order to more conveniently fix the connecting slide to the scaffolding and maintain the stability of the protective device, an optimization is made here and one of the feasible options is proposed: the connecting slide is provided with a locking member, and the locking member is used to connect the scaffolding and fix the connecting slide. When such a solution is adopted, there are several locking members, and at least two locking members are provided on one connecting slide.

[0016] Furthermore, when the width of the support protection needs to be adjusted, the distance between two adjacent connecting slides should change. In order to improve the flexibility of the protection device setting, optimization is performed here and one of the feasible options is proposed: the connecting frame includes a telescopic frame to maintain coordination when the distance between adjacent connecting slides changes. When such a solution is adopted, the telescopic frame can meet the installation requirements when the width changes.

[0017] Compared with the prior art, some beneficial effects of the technical solution disclosed in the present invention include:

[0018] The present invention adjusts the supporting protection range of the protective net by moving the movable net roller, which is convenient for adjusting the protection length in different construction stages, thereby meeting the demand for flexible adjustment of the protection range. At the same time, the movable net roller is locked and unlocked, and the protective net can be rolled up and unrolled, thereby maintaining the tension of the protective net and ensuring the protection effect.

[0025] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0026] In view of the fact that the structure of the protective net in the prior art is relatively complicated to set up, cannot be flexibly adjusted after setting, and can only be reinstalled to change the protection range, the following embodiments are optimized and overcome the defects in the prior art.

[0027] Example

[0028] like Figure 1 to Figure 3 As shown, this embodiment provides a horizontal protection device for scaffolding boards, including two connecting slides 1 for connecting to the scaffolding, a fixed mesh roller 9 is arranged at the front end of the connecting slide 1, and a movable mesh roller is also arranged on the connecting slide 1, and a protective net 8 is connected between the fixed mesh roller 9 and the movable mesh roller; the movable mesh roller is slidably arranged on the connecting slide 1 and reciprocates along the connecting slide 1 to approach or move away from the fixed mesh roller 9, and a driving structure for driving the movable mesh roller is arranged on the connecting slide 1; a lock is arranged on the movable mesh roller, and the lock is used to unlock the movable mesh roller to retract the protective net 8, or lock the movable mesh roller to tighten the protective net 8.

[0029] The protective device disclosed in this embodiment utilizes the movable mesh roller to approach or move away from the fixed mesh roller 9 to adjust the length of the protective distance. The protective net 8 can be tightened by adjusting the movable mesh roller through the lock, thereby ensuring that the protective net 8 can meet the protection needs. A larger protection range can be provided in the early stage of construction, and the required construction gap can be left in the later stage of construction. This improves the convenience of use and reduces the repetitive work of setting up the protective net 8.

[0030] In this embodiment, the structure of the movable net roller is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: the movable net roller includes a roller shaft 5, and a rotating sleeve 7 on the roller shaft 5 is provided with a roller sleeve for retracting the protective net 8, and the locking device is used to unlock the roller sleeve or lock the roller sleeve. When such a scheme is adopted, the rotating sleeve 7 rotates on the roller shaft 5, and the protective net 8 is rolled up or unrolled during the rotation process. The length of the protective net 8 can be adjusted according to the actual protection range. After the adjustment is in place, the roller sleeve is locked by the locking device, so that the protection range of the protective net 8 can be adjusted, and at the same time, the protective net 8 is kept taut to provide sufficient protection capability.

[0031] When the movable net roller is unlocked, the rotating sleeve 7 can rotate relative to the roller shaft 5, thereby realizing the winding and unwinding of the protective net 8. In order to make the rotating sleeve 7 automatically wind up, this embodiment optimizes the structure of the movable net roller and proposes the following feasible option: a reset member 6 is arranged between the roller shaft 5 and the rotating sleeve 7, and the reset member 6 applies a reset force to the rotating sleeve 7 to retract the protective net 8. When such a solution is adopted, the reset member 6 can be an elastic member, such as a spring, a torsion spring, etc. Under normal conditions, the reset member 6 maintains elastic deformation and applies an elastic reset force to the rotating sleeve 7. When the movable net roller is unlocked, the rotating sleeve 7 is wound up under the action of the reset force.

[0032] The structure of the lock is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: the lock includes a locking sleeve 4, which is sleeved on the end of the roller shaft 5, and the end of the roller shaft 5 is provided with a polygonal columnar section corresponding to the locking sleeve 4. The inner hole of the locking sleeve 4 is correspondingly polygonal and sleeved on the polygonal columnar section. The locking sleeve 4 slides back and forth along the axial direction of the polygonal columnar section, and an elastic push piece is provided on the roller shaft 5 to push the locking sleeve 4 to the middle of the roller shaft 5; a rotating card structure is provided between the rotating sleeve 7 and the locking sleeve 4. When the locking sleeve 4 is pushed to fit the rotating sleeve 7 and the rotating card structure is matched, the locking sleeve 4 locks the rotating sleeve 7. When the locking sleeve 4 leaves the rotating sleeve 7 and the rotating card structure is released, the rotating sleeve 7 is unlocked. When such a solution is adopted, the polygonal columnar segment cooperates with the locking sleeve 4 to prevent the locking sleeve 4 from circumferential deflection, and only axial displacement can occur; when the locking sleeve 4 moves axially to cooperate with the rotating sleeve 7, the rotating sleeve 7 is synchronously locked and its circumferential rotation is prevented. When the locking sleeve 4 moves axially and separates from the rotating sleeve 7, the rotating sleeve 7 can rotate circumferentially.

[0033] In this embodiment, the rotary clamping structure can adopt various forms, which are not limited to the only one. This embodiment is optimized and adopts one of the feasible options: the rotary clamping structure includes a rotary clamping groove and a rotary clamping tooth, and the rotary clamping groove and the rotary clamping tooth are correspondingly arranged on the fitting surface of the locking sleeve 4 and the rotating sleeve 7. When such a solution is adopted, the rotary clamping grooves are evenly spaced along the circumference, and the smaller the interval and the more the number of settings, the higher the locking accuracy.

[0034] Preferably, a groove matching the locking sleeve 4 is provided at the end of the rotating sleeve 7, one end of the locking sleeve 4 enters the groove, and a plurality of rotating teeth are provided on the locking sleeve 4, and a plurality of rotating slots are provided on the inner wall surface of the groove, and the rotating teeth are inserted into the rotating slots to achieve locking of the rotating sleeve 7.

[0035] In this embodiment, the elastic push member pushes the locking sleeve 4 toward the rotating sleeve 7. There are multiple options. This embodiment is optimized and adopts one feasible option: the elastic push member includes a spring. When such a solution is adopted, the spring can be coaxially arranged on the roller shaft 5, one end of which is connected and fixed to the end of the roller shaft 5, and the other end is pressed against the locking sleeve 4. When the locking sleeve 4 compresses the spring and moves toward the end of the roller shaft 5, the locking sleeve 4 is unlocked from the rotating sleeve 7.

[0036] When the protective length of the protective net 8 needs to be adjusted, the effect is achieved by adjusting the distance between the fixed net roller 9 and the movable net roller. The movable net roller's moving structure can be achieved in a variety of ways. This embodiment is optimized and adopts one of the feasible options: a linear slide groove is provided on the connecting slide 1, a slider 12 is provided in the linear slide groove, and the sliders 12 of adjacent connecting slides 1 are fixedly connected by a connecting frame 13; a threaded rod 3 is provided in the linear slide groove to cooperate with the slider 12 and drive the slider 12 to reciprocate along the linear slide groove, and the rear end of the threaded rod 3 protrudes from the rear end of the connecting slide 1 and is provided with a rotating head 2. When such a scheme is adopted, the slider 12 is moved along the linear slide groove by rotating the threaded rod 3, thereby driving the movable net roller to reciprocate. Under this structure, the distance between the movable net roller and the fixed net roller 9 can be adjusted to achieve the adjustment of the length of the protective net 8. At the same time, the distance can be kept stable by the characteristics of the threaded fit to avoid slippage.

[0037] Preferably, the slider 12 arranged in the linear slide groove is in the shape of an elongated strip, so as to maintain the stability of the movable mesh roller; or a plurality of sliders 12 are arranged in the same linear slide groove, so as to ensure stability.

[0038] In order to improve the convenience of adjusting the position of the movable net roller, the present embodiment optimizes the structure of adjacent movable net rollers, and the present embodiment adopts one of the feasible options: the front end or rear end of the threaded rod 3 is also provided with a synchronous gear 10, and the synchronous gears 10 of adjacent threaded rods 3 are connected and matched through a synchronous chain 11 to make the adjacent threaded rods 3 rotate synchronously. When such a scheme is adopted, the synchronous gear 10 rotates synchronously with the threaded rod 3, and the adjacent threaded rods 3 can rotate synchronously after being connected through the synchronous chain 11, thereby maintaining the synchronous movement of the two ends of the movable net roller, and improving the convenience of operation.

[0039] In order to more conveniently fix the connecting slide 1 to the scaffold and maintain the stability of the protective device, this embodiment is optimized and adopts one of the feasible options: the connecting slide 1 is provided with a locking member 14, and the locking member 14 is used to connect the scaffold and fix the connecting slide 1. When such a solution is adopted, there are a plurality of locking members 14, and at least two locking members 14 are provided on one connecting slide 1.

[0040] When the width of the support protection needs to be adjusted, the distance between two adjacent connecting slides 1 should be changed.

When such a solution is adopted, the telescopic frame can meet the installation requirements when the width changes.

Those skilled in the art can arbitrarily combine the above methods to obtain other various implementation methods. Anyone can derive other various implementation methods under the inspiration of this embodiment. The above specific implementation methods should not be understood as limiting the protection scope of this embodiment. The protection scope of this embodiment should be based on the definition in the claims.
