Description
TECHNICAL FIELD
[0001] The utility model relates to building construction technical field, especially a kind of flexible suspension device. BACKGROUND
[0002] When conveying power components in building, power conveying equipment such as bridge or bus duct is usually needed to place and convey power components. The laying method of bridge or bus duct is to use a boom structure to pull it to a position at a certain height from the ground, and then fix the bridge or bus duct. In the prior art, since the power conveying equipment needs to be laid in the whole building, a group of booms made of steel bars or steel pipes is usually used to suspend the bridge or bus duct under the floor of the building, and when the power components are placed on the bridge or in the bus duct, the weight of each boom needs to be the same.
[0003] However, due to the settlement of the building or its own deformation, the tension of the multiple booms supporting the bridge or bus duct on site is not the same. In the actual weight process, the weight of each boom may also be slightly different, which may cause the fixed position of some booms to loosen and the weight of each boom to be inconsistent. If the weight of some booms increases, it may cause the bridge or bus duct to bear a larger tension, resulting in deformation of the bridge or bus duct. If the overload of the boom weight is not found in time, it may cause the fixed position of the boom to loosen and sink, or even cause the boom to be pulled off, which may damage the power conveying equipment and endanger the life safety of the construction personnel.
[0004] Currently, there are several methods to detect whether the boom weight is overloaded: one method is to observe whether the bridge or bus duct deforms, but the deformation of the bridge or bus duct indicates that the boom has been overloaded for a long time, which is not conducive to the timely discovery of the boom overload; another method is to tighten all the booms regularly to timely discover the booms with insufficient weight, which requires the operator to tighten the fixed position of the boom one by one at a high place, which is difficult to construct and has low efficiency. In addition, the boom can also be knocked to detect whether it is overloaded, but this method may cause the fixed position of the boom to loosen and also cause the deformation of the boom. SUMMARY
[0005] To solve the technical problems in the prior art, the purpose of the utility model is to provide a flexible suspension device, which can timely discover the overload of the boom weight, thereby reducing the risk of deformation and falling of the power conveying equipment due to uneven force on each boom, avoiding damage to the power conveying equipment, and ensuring the life safety of the personnel on site.

[0024] In addition, the skilled person in the art can combine and combine the different embodiments or examples described in the present description and the features of the different embodiments or examples without contradiction.
[0025] As Figure 1The utility model provides a kind of flexible suspension device, including boom 1 and indicating component 2, one end of boom 1 and one end of indicating component 2 are fixed and suspended below predetermined plane 3, the other end of boom 1 is used to hang heavy object 4.Boom 1 has elastic section 11, elastic section 11 is used to extend along the length direction of boom 1 after being stressed.Indicating component 2 is used to show the extension of boom 1.
[0026] The present application does not limit the type of indicating component 2, which can be set as a ruler, but also can be set as other devices or components that can indicate the position of the boom 1.
[0027] It should be understood that the predetermined plane 3 in the present application refers to the plane for suspending the heavy object 4.In an illustrative embodiment, the predetermined plane 3 refers to the floor surface of a building.In another embodiment, the predetermined plane 3 can also refer to other devices or building planes that need to suspend heavy objects.
[0028] It should be noted that in the field of construction, the heavy object 4 includes but is not limited to power transmission equipment (such as pipes, bridge or bus duct, etc.).When the power transmission equipment is actually used, cables can be placed in the bridge or bus duct to deliver the cables to the designated position in the building.In other cases, the heavy object 4 can also be set as other components or equipment that need to be suspended under the boom 1 according to the needs.
[0029] In the prior art, when suspending heavy objects on the floor surface of a building, a set of booms are usually needed to support the heavy objects.Due to the settlement of the building or its own deformation, the weight carried by each boom 1 is different, which may, on the one hand, cause the fixed position of the boom 1 and the predetermined plane 3 to loosen, causing the boom 1 to sink and thus causing the bridge or bus duct to deform;on the other hand, when the weight of some booms 1 exceeds the weight limit, it may cause the boom 1 to fall, causing damage to the equipment or casualties.
[0030] The present application provides a kind of flexible suspension device, which can be widely used for lifting and pulling of heavy equipment, has simple structure and is easy to operate.The operator can intuitively observe the weight of each boom 1 during installation, inspection or maintenance, so as to timely find that the boom 1 is overloaded, thereby preventing the boom 1 from loosening or falling, reducing the risk of deformation or falling of the power transmission equipment caused by uneven force on each boom 1, avoiding damage to the power transmission equipment, and ensuring the safety of on-site personnel.
[0031] In addition, the flexible suspension device can also absorb the vibration force of the boom 1 when the surrounding ground or device vibrates (such as during an earthquake), to avoid loosening or falling of the boom 1 when vibrating.
[0032] Specifically, the flexible suspension device has a hanger 1 and an indicating component 2. The hanger 1 is provided with an elastic section 11, which can be elongated when the hanger 1 suspends a heavy object 4, and the indicating component 2 is used to detect the elongation of the hanger 1. When installing or inspecting, an operator can know the weight of each hanger 1 by observing the indicating component 2. When the indicating component 2 detects that the elongation of the hanger 1 is greater than a preset value, it indicates that the weight of the heavy object suspended below the hanger 1 has exceeded the weight limit of the hanger 1, and the excessive elongation of the elastic section 11 of some hangers 1 can cause resonance effect between multiple hangers 1, which affects the power transmission equipment. When the operator finds that the hangers 1 are unevenly loaded, the number of hangers 1 can be increased as needed to evenly distribute the load to each hanger 1, thereby preventing uneven stress on the hangers 1 from causing deformation or falling of the cable, bridge or bus duct.
[0033] Further, when the weight of the heavy object 4 below the hanger 1 exceeds the weight limit of the hanger 1, the hanger 1 can loosen, causing the hanger 1 to sink, thereby increasing the elongation of the hanger 1. The hanger 1 and the indicating component 2 are fixed on the predetermined plane 3 respectively in the present application, and the elongation of the hanger 1 relative to the predetermined plane 3 (including the sinking amount of the loosened hanger 1 relative to the predetermined plane 3 and the elongation of the elastic section 11) can be detected by the indicating component 2, which can more accurately predict the risk of sinking or falling of the hanger 1 and ensure the safety of the power transmission equipment during use.
[0034] It should be noted that if the hanger 1 loosens and sinks relative to the predetermined plane 3, the hanger 1 can also fall when the elastic section 11 of the hanger 1 does not reach the elongation limit. The present application can detect the sum of the sinking amount of the hanger 1 and the elongation of the elastic section 11 by the indicating component 2, thereby more accurately judging the elongation of the hanger 1 relative to the predetermined plane 3, so as to further reduce the risk of falling of the hanger 1.
[0035] Referring to Figure 1 , in a preferred example, the indicating component 2 is provided as a scale, and the hanger 1 and / or the scale are fixed on the predetermined plane 3 by bolts. In a specific example, the hanger 1 and the scale can be fixed on the floor surface of a building by expansion bolts.
[0036] Continuing to refer to Figure 1 , as a preferred solution, the elastic section 11 is spirally wound along the circumference of the hanger 1.
[0037] As another preferred solution, the hanger 1 includes two straight rods 12, and the elastic section 11 is provided as a spring, preferably a spring with a high elastic coefficient, and the two ends of the spring are connected to one of the straight rods 12, thereby forming the hanger 1 with the elastic section 11.
[0038] Further, the boom 1 is provided with a mark point 13, which is arranged below the elastic section 11. The scale is provided with a scale line, and the mark point 13 is used to correspond to the scale line on the scale to show the elongation of the boom 1. In this way, the position of the scale line on the scale to which the mark point 13 on the boom 1 is aligned is the elongation of the boom 1.
[0039] With reference to the drawings Figure 1 In an example, the mark point 13 is arranged as an indication arrow fixed on the boom 1.
[0040] In another example, the mark point 13 is arranged as an indication line on the boom 1. For example, the mark point 13 can be arranged as an indication line engraved or pasted on the boom 1.
[0041] With reference to the drawings Figure 1 In a preferred embodiment, the boom 1 is arranged in parallel with the scale, so that the mark point 13 on the boom 1 can correspond to the scale line on the scale.
[0042] In other embodiments, the boom 1 can also be arranged at an angle with the scale, and the arrangement position of the boom 1 and the scale only needs to satisfy that the scale can indicate the elongation position of the boom 1.
[0043] In other embodiments, the boom 1 can also be arranged at an angle with the scale, and the arrangement position of the boom 1 and the scale only needs to satisfy that the scale can indicate the elongation position of the boom 1.
[0044] With reference to the drawings Figure 1 As shown, the lower end of the boom 1 (i.e. the other end of the boom 1) is provided with a thread (not shown), and the lower end of the boom 1 is used to extend into the weight 4 and is used to cooperate with a nut (not shown) to realize the connection of the weight 4 and the boom 1. Specifically, after the lower end of the boom 1 extends into the weight 4, the nut can be extended into the weight 4 to be threadedly connected with the lower end of the boom 1, and then the bridge or the bus duct is fixed at the lower end of the boom 1.
[0045] In summary, the utility model provides a kind of flexible suspension device, the flexible suspension device can be widely used in the lifting and pulling of heavy equipment, and has simple structure and is easy to operate. The operator can intuitively observe the load condition of each boom 1 during installation, inspection or maintenance, so as to timely discover the overload of the boom 1, thereby preventing the boom 1 from loosening or falling off, reducing the risk of deformation or falling of the power transmission equipment caused by uneven force on each boom 1, avoiding damage to the power transmission equipment, and ensuring the safety of on-site personnel.
[0046] In addition, the flexible suspension device can also absorb the vibration force of the boom 1 when the surrounding ground or device vibrates (such as during an earthquake), to avoid the boom 1 from loosening or falling off during vibration.
