Description

Technical Field

[0001] The utility model is applicable to the technical field of scaffolds and provides an insulating scaffold for preventing electric shock. Background Art

[0002] Scaffolding is a structure used to support and provide support for workers while they are constructing, repairing or renovating a building. They are usually made of metal alloys and provide a stable platform for workers to work safely and to operate at height or in hard-to-reach areas.

[0003] The scaffolding currently available on the market plays an important role in the installation of electrical equipment. When building or repairing electrical equipment, the scaffolding provides support and a working platform, enabling workers to safely install, maintain or repair various electrical equipment, such as lighting systems, power lines, control panels, etc. The stability and adjustability of the scaffolding make it an indispensable tool when installing electrical equipment.

[0004] However, today's scaffolding has some potential hazards in terms of preventing electric shock. Since scaffolding is usually made of metal or other conductive materials, and in order to facilitate disassembly and movement, scaffolding does not have good protection against electric shock. When workers are operating at heights, if they accidentally touch electrical equipment, their bodies become conductors, and the current directly passes through the human body and the scaffolding to form a path to the ground, there is a great risk of electric shock for workers. Utility Model Content

[0005] In view of the above-mentioned defects, the purpose of the utility model is to provide an insulating scaffolding for preventing electric shock, in order to solve the problems raised in the background technology, including a scaffolding unit composed of a plurality of vertical rods and side cross rods, a connecting body is installed between the upper and lower vertical rods, and a bearing platform and a lap rod are arranged between the two groups of the scaffolding units; the bearing platform includes a platform frame and an insulating plate installed on the platform frame, the platform frame is lapped on the scaffolding unit through a second lap claw, and a first insulating layer is fixedly connected to the inner side of the second lap claw; the lap rod is lapped on the scaffolding unit through a lap body, the lap body includes a plug-in part and a first lap claw fixedly connected to each other, the plug-in part is sleeved in the lap rod, a cavity is arranged inside the first lap claw, a locking card is hinged in the first lap claw through a hinge point, and a second insulating layer and a third insulating layer are respectively installed on the inner sides of the first lap claw and the locking card.

[0006] Furthermore, the connector includes a lower connector and an upper connector with one end sleeved inside the lower connector, and an insulating sleeve is sleeved on the top of the upper connector.

[0007] Furthermore, an operating tooth is installed at one end of the locking member away from the hinge point, a limiting tooth is installed on the locking member, the limiting tooth abuts against the inside of the plug-in part, and a spring is installed between the locking member and the first overlapping claw.

[0008] Furthermore, a foot pad is fixedly connected to the bottom of the vertical rod.

[0009] Furthermore, a plurality of rotating cards are installed on the platform frame, and the rotating cards can be rotated to the top of the insulating plate.

[0010] Furthermore, the vertical rods, side cross rods, platform frames and lap rods are all sprayed with an insulating paint layer.

[0011] Furthermore, a gasket is sleeved on the insulating sleeve.

[0012] In summary, the technical solution can prevent workers from getting electric shocks from four aspects. First, the insulating plate is made of non-conductive material, which can prevent the power points touched by workers from forming a power path between their feet and the scaffolding. Second, there is a first insulating layer between the second overlapping claw of the platform frame and the scaffolding unit, which can provide further insulation protection on the basis of the previous technical solution. Third, the overlapping rod serves as both a guardrail and a handrail, and the overlapping bodies at both ends are isolated from the side cross bars by a second insulating layer and a third insulating layer, which can prevent the workers from forming a power path between the power points they touch and the overlapping rod when holding the overlapping rod; at the same time, the surface of the overlapping rod is sprayed with an insulating paint layer, which can further isolate the current. Fourthly, the connector can isolate the electrical connection between the upper and lower vertical poles. The vertical pole at the top is sleeved on an insulating sleeve, and the bottom is in contact with the insulating sleeve through a gasket to prevent damage. It ensures good insulation while ensuring the connection strength and resistance to damage, so that the current cannot be conducted from top to bottom of the scaffolding, thereby maximizing the insulation of the scaffolding and preventing workers from getting electric shock during operation.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] See also Figure 1-6 The purpose of the utility model is to provide an insulating scaffold for preventing electric shock, including a scaffold monomer, which is composed of two vertical rods 1 and a plurality of side cross bars 2 fixedly connected between the vertical rods 1. The two scaffold monomers are arranged in parallel, and a fork-shaped connecting piece is obliquely installed between the two scaffold monomers to ensure the stability of the scaffold (in order to make the drawings simple, the connecting piece has been omitted in the drawings).

[0022] A bearing platform 3 and a lap rod 4 are installed between two groups of scaffolding monomers arranged horizontally, and a connector 6 is installed between two groups of scaffolding monomers arranged vertically. The bearing platform 3 is a working platform of the scaffolding, and the bearing platform 3 is set up between the two groups of scaffolding monomers to provide a work foothold for the staff. The lap rod 4 is set up on the side cross bars 2 of the two groups of scaffolding monomers, which can provide a working handrail and safety barrier for the staff. The function of the connector 6 is to connect the upper and lower layers of scaffolding, that is, the upper and lower vertical rods 1 are connected by the connector 6.

[0023] The supporting platform 3 includes a platform frame 31, on which a plurality of second overlapping claws 33 are installed, and the platform frame 31 is overlapped on the scaffolding unit through the plurality of second overlapping claws 33. Specifically, two second overlapping claws 33 are installed on both sides of the platform frame 31. The second overlapping claws 33 are C-shaped structures, and the inner side of the C-shaped structure is fixedly connected with a first insulating layer 331, and the first insulating layer 331 is an insulating material, such as rubber or ceramic material. An insulating plate 32 is installed on the top of the supporting platform 3. Specifically, the platform frame 31 includes reinforcing ribs that are criss-crossed to form a grid. The insulating plate is placed on top of the reinforcing ribs, and the staff members step on the insulating plate 32 to work.

[0024] The lap rod 4 is lapped on the side cross bar 2 through the lap body 5. The lap body 5 includes a plug-in portion 51 and a first lap claw 52 that are fixedly connected to each other. The plug-in portion 51 can be sleeved in the lap rod 4. A cavity is provided inside the first lap claw 52. A locking member 53 is hinged in the cavity of the first lap claw 52 through a hinge point. Both the first lap claw 52 and the locking member 53 are C-shaped structures. The inner sides of the C-shaped structures of the first lap claw 52 and the locking member 53 are respectively installed with a second insulating layer 521 and a third insulating layer 533. An operating tooth 532 is fixedly connected to the end of the locking member 53 away from the hinge point. A limiting tooth 531 is fixedly connected to the locking member 53. The limiting tooth 531 can extend into the internal channel of the plug-in portion 51 and abut against the inside of the plug-in portion 51. A spring 54 is installed between the locking member 53 and the internal cavity of the first lap claw 52.

[0025] The first overlap claw 52 of the C-shaped structure can overlap the overlap rod 4. After overlap, the second insulating layer 521 on the first overlap claw 52 contacts the overlap rod 4, electrically isolating the first overlap claw 52 from the overlap rod 4; the third insulating layer 533 on the locking member 53 contacts the overlap rod 4, electrically isolating the locking member 53 from the overlap rod 4; thus, no conductive path can be formed between the overlap rod 5 and the side cross bar, achieving the purpose of insulation.

[0026] The connector 6 includes a lower connector 62 and an upper connector 61 with one end sleeved inside the lower connector 62. The top of the upper connector 61 is sleeved with an insulating sleeve 63. The top of the insulating sleeve 63 and the bottom of the lower connector 62 are both sleeved on the outside of the vertical rod 1. The insulating sleeve 63 can isolate the electrical connection between the upper and lower groups of vertical rods 1 to prevent current from being conducted downward.

[0027] Preferably, the bottom of the vertical rod 1 is fixedly connected with a foot pad 11. Specifically, the foot pad 11 is installed at the contact point between the scaffolding monomer at the bottom layer and the ground. The foot pad 11 is made of a non-conductive non-metallic material, which can isolate the electrical connection between the vertical rod 1 and the ground, further achieving the purpose of insulation.

[0028] Preferably, a plurality of rotating cards 311 are installed on the platform frame 31, and the rotating cards 311 can rotate on the platform frame 31, and the rotating cards 311 can rotate to the top of the insulating plate 32 to lock the insulating plate 32 on the platform frame 31, so as to prevent the insulating plate 32 from falling off from the platform frame 31.

[0029] Preferably, the vertical rods 1 , the side cross rods 2 , the platform frame 31 , and the lap rods 4 are all sprayed with an insulating paint layer.

[0030] Preferably, a washer 64 is sleeved on the insulating sleeve 63. The washer 64 is made of insulating material such as rubber or plastic. When the vertical rod 1 is sleeved on the insulating sleeve 63, the bottom of the vertical rod 1 abuts against the washer 64, which can further achieve the purpose of insulation.

[0031] In summary, the present technical solution can prevent workers from getting electric shocks from four aspects. On the first aspect, the insulating plate 32 is made of non-conductive material, which can prevent the power source points touched by the workers from forming a power path between their feet and the scaffolding. On the second aspect, there is a first insulating layer 331 between the second overlapping claw 33 of the platform frame and the scaffolding monomer, which can provide further insulation protection on the basis of the previous technical solution. On the third aspect, the overlapping rod 4 serves as both a guardrail and a handrail, and the overlapping bodies 5 at both ends are isolated from the side cross bars 2 by a second insulating layer 521 and a third insulating layer 533, which can prevent the workers from forming a power path between the power source points they touch and the overlapping rod 4 when holding the overlapping rod 4; at the same time, the surface of the overlapping rod 4 is sprayed with an insulating paint layer, which can further isolate the current. Fourthly, the connector 6 can isolate the electrical connection between the upper and lower vertical rods 1. The vertical rod 1 at the top is sleeved on the insulating sleeve 63, and the bottom is in contact with the insulating sleeve 63 through the gasket 64 to prevent damage. It ensures good insulation while ensuring the connection strength and non-destructiveness, so that the current cannot be transmitted from top to bottom of the scaffolding, thereby maximizing the insulation of the scaffolding and preventing workers from being electric shocked during the operation.

[0032] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
