Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1:

the embodiment provides an external frame protection device, as shown in fig. 1, which includes a protection net 1, a fixing rod 2 and first hooks 3 arranged at two ends of the fixing rod 2;

the fixing rod 2 comprises a long rod 21 and a short rod 23 connected below the long rod 21 through a spring 22;

the first hook 3 is made of inelastic metal and is in a coil spring shape;

the top end of the fixed rod 2 is connected with a limiting ball 5 through a fixed rope 4, the fixed rope 4 shuttles back and forth in meshes of the protective net 1 under the pulling of the limiting ball 5 and is finally wound on the fixed rod 2, and the limiting ball 5 is fixed on a long rod 21 or a short rod 23.

When the outrigger protector in this application uses, can hang the couple at 2 both ends of dead lever on the steel pipe about the scaffold frame respectively earlier, realize dead lever 2 fixed, then be suitable for fixed rope 4 and twine dead lever 2 and protection network 1, fix protection network 1 and dead lever 2, then fix spacing ball 5 on stock 21 or quarter butt 23 for fixed rope 4 keeps fastening the state. The fixing rod 2 and the anti-slip net are fixed in a winding mode of the fixing rope 4, and the installation and the disassembly are simple and efficient.

The outer frame protection device of the embodiment is safe and reliable, can be repeatedly used, saves cost, is very convenient to assemble and disassemble, and is favorable for improving the construction efficiency.

The outrigger protector of this embodiment except that protection network 1, other subassemblies are all interconnect, can not cause losing of part in convenient transportation and dismouting transportation, conveniently keeps.

The fixing rod 2 comprises a long rod 21 and a short rod 23 connected by a spring 22, so that the length of the fixing rod 2 can be adjusted as required, and the external frame protection device can be adapted to external frames with various specifications and sizes.

The hook is in a coil spring shape, so that the fixed rod 2 can be prevented from being separated from the steel pipe of the scaffold in the up-and-down moving process, and potential safety hazards are generated.

Example 2:

this embodiment further defines, on the basis of embodiment 1: be provided with solid fixed ring on stock 21 or the quarter butt 23, gu be provided with the breach that is used for fixed rope 4 to pass through on the fixed ring, the width of breach or solid fixed ring's diameter all are less than spacing ball 5's diameter.

Fixed rope 4 wears from the breach into solid fixed ring, because the diameter of spacing ball 5 is greater than solid fixed ring's diameter, under the pulling force effect of fixed rope 4, spacing ball 5 also can't leave from solid fixed ring, has realized the fixed of spacing ball 5. The fixing mode is simple and efficient in mounting and dismounting operation, and the construction efficiency can be improved to a great extent.

Example 3:

this embodiment further defines, on the basis of embodiment 2: the fixing ring is made of an inelastic metal material and is in a coil spring shape.

The fixing ring is in a spiral spring shape, so that the fixing rope 4 can be prevented from being separated from the fixing ring, the fixing rope 4 is loosened, the fixing rope 4 and the protective net 1 are kept stable, and potential safety hazards are reduced.

Example 4:

this embodiment further defines, on the basis of embodiment 3: the number of the long rods 21 and/or the short rods 23 is more than two, and the adjacent long rods 21 or the short rods 23 are connected through springs 22.

In general, the long rod 21 is located below the short rod 23, so that the gravity applied to the spring 22 can be reduced, and the deformation of the spring 22, which is difficult to recover due to large pulling force, can be avoided. However, under the condition that the size change range is large, the deformation of one spring 22 is difficult to meet the requirement, so a plurality of springs 22 can be arranged, and the adjustable range of the length of the fixed rod 2 is increased. However, since the spring 22 is more likely to be deformed so as to be difficult to recover as the tension of the lower member to be received increases, it is necessary to select the position of the spring 22 and the specification and material of the spring 22 according to the specific situation in actual use.

Example 5:

this embodiment further defines, on the basis of embodiment 4: the two sides of the fixed rod 2 are provided with safety pins for assisting in fixing the protective net 1.

Although the protection net 1 can be fixed to the scaffold by simply relying on the function of the fixing rope 4, a pin is provided to be fixed to the protection net 1 to assist in fixing in order to improve the stability of the device.

Example 6:

this example further defines, on the basis of example 5: the bearing further comprises a bearing, wherein an inner ring of the bearing is fixed with the first hook 3, and an outer ring of the bearing is fixed with the fixing rod 2.

The fixed ring and the first hook 3 can rotate relatively, the protective net 1 and the fixed rod 2 can be fixed firstly during installation, and then the direction of the first hook 3 can be adjusted according to the direction of the scaffold steel pipe, so that the first hook 3 and the scaffold are fixed conveniently.

Although the invention has been described herein with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this invention. More specifically, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, other uses will also be apparent to those skilled in the art.
