Description

Technical Field

[0001] The present invention relates to the technical field of scaffolding, and specifically relates to an anti-falling device externally hung on a socketed scaffolding. Background Art

[0002] The socketed scaffolding support is composed of accessories such as vertical poles, horizontal bars, diagonal bars, adjustable bases and adjustable socket heads, etc. The main composition method is as follows: the vertical poles are connected by sleeve socket joints, and the horizontal bars and diagonal bars are connected by inserting the rod end buckle joints into the connecting plates and then connecting them with wedge-shaped pins to form a steel pipe support with a geometrically invariant structure.

[0003] During building construction, it is necessary to install step ladders, pedals and steel exterior wall protection nets on the scaffolding for combined use. Since the pedals are installed on the scaffolding in a movable lapping manner, the following safety problems will exist: 1. When construction workers walk on them, the pedals are prone to shaking. The longer the pedals are used, the more obvious the shaking is. When the construction workers shake with the pedals, they are prone to slipping and falling if they are not careful. And the long-term shaking makes the movable lapping joints of the pedals on the scaffolding prone to slipping, resulting in unstable joints and easy occurrence of pedal falling, posing a safety hazard.

[0004] 2. At the same time, when construction workers are working, they need to walk back and forth on the pedals frequently. The center position of the pedals is more prone to fatigue fracture when continuously bearing gravity. If the construction workers do not discover it in time, they are prone to stepping into the air and falling, causing safety accidents.

[0005] Therefore, in order to solve the problems of pedal shaking and easy fracture at the center of the pedals, the present invention provides an anti-falling device externally hung on a socketed scaffolding. Summary of the Invention

[0006] The present invention provides an anti-falling device externally hung on a socketed scaffolding to solve the problems of pedal shaking and easy fracture at the center of the pedals in the related art.

[0007] The present invention provides an anti-falling device externally hung on a socketed scaffolding, including: a main body plate and hanging parts. Two hanging parts are provided at both the left and right ends of the main body plate, and the distance between the two hanging parts on the left is less than the distance between the two hanging parts on the right.

[0008] A stepped groove is opened at the upper end of the main body plate. A first set of springs arranged in a matrix are fixedly installed on the inner bottom wall surface of the stepped groove. The upper ends of the first set of springs are fixedly connected together with a wire mesh. The wire mesh is fixedly connected to the circumferential inner wall surface of the stepped groove. A square pedal is fixedly installed on the stepped groove and above the wire mesh. Tight contact components are symmetrically arranged at the front and rear ends of the main body plate.

[0009] The hanging part includes a clamping set. The clamping set is fixedly installed on the main body plate. A square clamping groove is formed in the clamping set. Elastic fasteners are symmetrically arranged on the left and right inner wall surfaces of the square clamping groove.

[0010] In one embodiment, the tight contact assembly includes a telescopic positioning member, a second spring, and a sliding plate. Slideway grooves one are symmetrically formed at the front and rear ends of the main body plate. Telescopic positioning members are uniformly fixedly installed on the vertical end surfaces of the slideway grooves one. The other ends of the telescopic positioning members are fixedly connected to the sliding plate together. Second springs are sleeved on the telescopic positioning members. One end of each second spring is connected to the vertical end surface of the slideway groove one, and the other end is connected to the sliding plate. The sliding plate is in sliding fit with the slideway groove.

[0011] In one embodiment, the elastic fastener includes a third spring and a sliding convex block. Slideway grooves two are symmetrically formed on the left and right inner wall surfaces of the square clamping groove. Third springs arranged in a matrix are fixedly installed on the vertical end surfaces of the slideway grooves two. The other ends of the third springs are fixedly connected to the sliding convex block together. The sliding convex block is in sliding fit with the slideway groove two.

[0012] In one embodiment, a first rubber member is fixedly installed on the inner top surface of the square clamping groove.

[0013] In one embodiment, a second rubber member is fixedly installed at the end of the sliding plate away from the telescopic positioning member.

[0014] In one embodiment, a third rubber member is fixedly installed at the end of the sliding convex block away from the third spring.

[0015] In summary, the present invention includes at least one of the following beneficial technical effects: 1. The present invention provides an external anti-falling device for a socketed scaffolding. The elastic fasteners provided can assist the clamping set to clamp the horizontal bars on the left and right sides, making the installation of the hanging part more stable. The tight contact assembly provided can respectively contact and press against the horizontal bars on the front and rear sides, stabilizing the front and rear positions of the main body plate on the scaffolding and preventing the main body plate from shaking. The cooperation between the hanging part and the tight contact assembly effectively avoids the situation of falling caused by the instability of the connection part and shaking. When the construction worker steps on the square pedal, the first spring provided can buffer the stepping force, making the service life of the square pedal longer. Even if the middle part of the square pedal breaks after reaching a certain service limit, due to the wire mesh arranged under the square pedal, it can play a certain role in receiving and protecting, and can effectively avoid the situation of construction worker falling.

[0016] 2. The tight contact component provided in the present invention pushes out the sliding plate through the elastic force of the second spring, so that the second rubber part at the front end of the sliding plate is tightly attached to the horizontal rods on the front and rear sides, to compensate for the gap between the main body plate and the horizontal rods on the front and rear sides, and can prevent the main body plate from sliding back and forth, making the device more stable and greatly improving the overall safety.

[0017] 3.

Detailed implementation manners

[0028] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Please refer to Figure 1 and Figure 7 , a hanging anti-falling device for a socketed scaffolding, comprising: a main body plate 1 and a hanging member 2. Two hanging members 2 are provided at both left and right ends of the main body plate 1, and the distance between the two left hanging members 2 is less than the distance between the two right hanging members 2.

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a stepped groove is formed at the upper end of the main body plate 1. First springs 3 arranged in a matrix are fixedly installed on the inner bottom wall surface of the stepped groove. The upper ends of the first springs 3 are fixedly connected together with a wire mesh 4. The wire mesh 4 is fixedly connected to the circumferential inner wall surface of the stepped groove. A square pedal 5 is fixedly installed on the stepped groove and above the wire mesh 4. Tight contact assemblies 6 are symmetrically arranged at the front and rear ends of the main body plate 1.

[0031] Please refer to Figure 2 and Figure 5 , the hanging member 2 includes a card set 21. The main body plate 1 is fixedly installed with the card set 21. A square card slot is formed on the card set 21. A first rubber member 210 is fixedly installed on the inner top end surface of the square card slot. Elastic fasteners 22 are symmetrically arranged on the left and right inner wall surfaces of the square card slot.

[0032] When the device is put into use, it only needs to be connected to the constructed disc-type scaffolding. The specific operation is to move the device to the installation location on the scaffolding, and then adjust the position so that the square card slot on the card set can be carded on the horizontal bars on the left and right sides. The horizontal bars can be clamped by the elastic fasteners 22, so that the installation of the hanging part 2 is more stable; the set tight contact component 6 can be respectively contacted and pressed with the horizontal bars on the front and rear sides to stabilize the front and rear positions of the main board 1 on the scaffolding and prevent the main board 1 from shaking; when the construction workers step on the square pedal 5, the set spring 3 can buffer the stepping force, so that the service life of the square pedal 5 is longer. Even if the middle part of the square pedal 5 breaks after reaching a certain usage limit, since the wire mesh 4 is provided on the lower side of the square pedal 5, it can play a certain role in receiving and protecting, and can effectively avoid the construction workers from falling.

[0033] See also Figure 4 and Figure 6 The tight contact component 6 includes a telescopic positioning member 61, a spring 2 62 and a sliding plate 63. The front and rear ends of the main body plate 1 are symmetrically provided with a slideway groove 1. The vertical end surface of the slideway groove 1 is evenly fixed with the telescopic positioning member 61. The other end of the telescopic positioning member 61 is commonly fixedly connected with the sliding plate 63. The telescopic positioning member 61 is sleeved with a spring 2 62. One end of the spring 2 62 is connected to the vertical end surface of the slideway groove 1, and the other end is connected to the sliding plate 63. The sliding plate 63 and the slideway groove are slidably matched. The end of the sliding plate 63 away from the telescopic positioning member 61 is fixedly installed with a rubber member 2 630.

[0034] During the process of placing the main plate 1, the sliding plate 63 is subjected to an extrusion force, and the telescopic positioning member 61 and the spring 2 62 can bring the sliding plate 63 into the sliding groove 1. After being placed, the sliding plate 63 is pushed out under the elastic force of the spring 2 62, so that the rubber member 2 630 at the front end of the sliding plate 63 is tightly attached to the horizontal bars on the front and rear sides, so as to compensate for the gap between the main plate 1 and the horizontal bars on the front and rear sides, which can prevent the main plate 1 from sliding forward and backward, thereby improving the overall safety.

[0035] See also Figure 2 , Figure 3 and Figure 5 The elastic fastener 22 includes a spring three 221 and a sliding protrusion 222. The left and right inner walls of the square card slot are symmetrically provided with slideway grooves two. The vertical end surfaces of the slideway grooves two are fixedly installed with springs three 221 arranged in a matrix. The other ends of the springs three 221 are fixedly connected with the sliding protrusion 222. The sliding protrusion 222 and the slideway grooves two are slidably matched. The end of the sliding protrusion 222 away from the spring three 221 is fixedly installed with a rubber part three 223.

[0036] When the square card slot is clamped on the horizontal bars on the left and right sides, the sliding block is clamped on the left and right ends of the horizontal bar through the elastic force of spring three 221, so that the card set 21 and the horizontal bar are stable. The rubber part 1 210 and the rubber part 2 630 are used in conjunction with the card set 21 to ensure that the contacting horizontal bars are not worn and prevent the main plate 1 from sliding, making the whole more stable and safe.

[0037] The working principle of the present invention is as follows: the device is moved to the location to be installed on the scaffolding, and then the position is adjusted so that the square slot can be inserted into the horizontal bars on the left and right sides. The horizontal bars can be clamped by the elastic fasteners 22, so that the installation of the hanging part 2 is more stable; the tight contact component 6 can be respectively contacted and pressed against the horizontal bars on the front and rear sides to stabilize the front and rear positions of the main plate 1 on the scaffolding and prevent the main plate 1 from shaking; when the construction personnel step on the square pedal 5, the spring 3 can buffer the stepping force, so that the service life of the square pedal 5 is longer. Even if the middle part of the square pedal 5 breaks after reaching a certain usage limit, since the wire mesh 4 is provided on the lower side of the square pedal 5, it can play a certain role in receiving and protecting, and can effectively avoid the construction personnel from falling.
