Description

Technical Field

[0001] The present invention belongs to the technical field of installation and maintenance equipment, and particularly relates to a roller skating lifting structure and a tower. Background Art

[0002] The installation and maintenance work of communication towers generally needs to be carried out in a high-altitude environment, which not only has a high operation difficulty but also has a large safety risk. Therefore, special lifting equipment needs to be set up to meet the corresponding installation and maintenance requirements.

[0003] Existing lifting equipment usually uses a hydraulic lifting system or a gear and rack lifting mechanism to carry out lifting operations. However, when the distance required for lifting is large, it will lead to a high overall maintenance cost of the set hydraulic lifting system, and the stability and safety are extremely vulnerable to external environmental factors due to excessive acting forces during the lifting process. If a gear and rack lifting mechanism is set, due to its high requirements for the accuracy of installation and use and its relatively complex overall structure, it is very easy to cause the inability to carry out normal lifting operations due to wear during long-term use.

Specific embodiments

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Refer to Figure 1 and Figure 2 An roller skating lifting structure is provided in an embodiment of the present invention, including: a first arm 100, a second arm 200, a third arm 300, and a driving assembly 600. The second arm 200 is coaxially and slidably inserted into the first arm 100, and the third arm 300 is coaxially and slidably inserted into the second arm 200. The driving assembly 600 is disposed between the first arm 100 and the second arm 200, and the driving end of the driving assembly 600 can drive the second arm 200 to move axially along the first arm 100. A first cable 320 is disposed between the third arm 300 and the first arm 100, and the first cable 320 is movably connected to the driving assembly 600, so that the driving assembly 600 can drive the two ends of the first cable 320 to move relatively.

[0042] Specifically, the first boom 100, the second boom 200, and the third boom 300 are coaxially slidably sleeved in sequence. The second boom 200 is coaxially slidably inserted into the first boom 100 from one end of the first boom 100, and the third boom 300 is coaxially slidably inserted into the second boom 200 from the end of the second boom 200 away from the first boom 100. Among them, the driving assembly 600 is arranged between the first boom 100 and the second boom 200. The driving end of the driving assembly 600 is connected to the second boom 200. Through the driving end of the driving assembly 600, the second boom 200 can be driven to move along the axial direction of the first boom 100 towards or away from the first boom 100, so as to realize the lifting operation of the second boom 200. And, a first cable 320 is connected between the third boom 300 and the first boom 100. One end of the first cable 320 is connected to the first boom 100, and the other end of the first cable 320 movably passes through the driving end of the driving assembly 600 and is connected to the third boom 300, so that a part of the first cable 320 is located between the first boom 100 and the driving end of the driving assembly 600, and the other part of the first cable 320 is located between the driving end of the driving assembly 600 and the third boom 300. Thus, by the movement of the driving end of the driving assembly 600, the distance between the first boom 100 and the driving end of the driving assembly 600 can be changed, and accordingly the length of the first cable 320 located between the first boom 100 and the driving end of the driving assembly 600 can be changed. Furthermore, the length of the first cable 320 located between the driving end of the driving assembly 600 and the third boom 300 can be changed together, realizing the relative movement between the two ends of the first cable 320. Thereby, by changing the length of the first cable 320 located between the driving end of the driving assembly 600 and the third boom 300, the distance between the driving end of the driving assembly 600 and the third boom 300 can be changed, so as to realize the lifting operation of the third boom 300. When the driving end of the driving assembly 600 drives the second boom 200 to lift or lower, the acting force generated by the second boom 200 acts on the driving assembly 600. And when the third boom 300 lifts or lowers, the acting force generated by the third boom 300 acts on the first cable 320, thus realizing the sharing of the acting force, improving the stability during the lifting process, avoiding the influence on the stability due to excessive acting force during lifting, reducing the probability of being affected by external environmental factors, and further ensuring the safety during lifting. At the same time, the connection form using the cable can greatly reduce the requirement for the installation accuracy, reduce the probability of being unable to perform the normal lifting operation due to wear, and the overall structure is relatively flexible and compact, being convenient for use and operation and occupying less space. It is not only convenient for transportation and storage, but also can greatly reduce the working intensity of installation and maintenance when installation and maintenance are required, improve the operation efficiency, simplify the maintenance process, and reduce the maintenance cost.Moreover, through the modular connection setting among the first boom 100, the second boom 200 and the third boom 300, it is convenient for installation and disassembly, and the operation preparation time is shortened.

[0043] In some specific embodiments of the present invention, referring to Figure 1 and Figure 2 , the fixed end of the driving component 600 is fixedly connected to the first boom 100. The driving end of the driving component 600 is fixedly connected to the second boom 200. The driving end of the driving component 600 can move axially along the first boom 100 relative to the fixed end of the driving component 600.

[0044] Specifically, the driving component 600 is provided with two ends along the axial direction of the first boom 100. One end is the fixed end of the driving component 600 for fixedly connecting with the first boom 100, and the other end is the driving end of the driving component 600 for fixedly connecting with the second boom 200. Among them, the driving end of the driving component 600 can move axially along the first boom 100 relative to the fixed end of the driving component 600, thereby driving the second boom 200 to move axially along the first boom 100 together with the first boom 100, so as to realize the lifting of the second boom 200.

[0045] In some specific embodiments of the present invention, referring to Figure 1 and Figure 2 , the driving component 600 is a hydraulic cylinder, so that both ends of the telescopic shaft of the hydraulic cylinder respectively form the fixed end and the driving end of the driving component 600. The driving component 600 is arranged inside the first boom 100. The fixed end of the driving component 600 is connected to the bottom of the first boom 100 through an oil cylinder locking pin. The driving end of the driving component 600 extends axially along the first boom 100 towards the direction close to the second boom 200 and extends into the second boom 200 and is connected to the second boom 200, thereby realizing the installation of the driving component 600. The structure is relatively flexible and compact, which is convenient for installation and maintenance.

[0046] In some specific embodiments of the present invention, referring to Figure 1 and Figure 2 , a first outrigger wheel 610 is rotatably arranged on the driving end of the driving component 600. The first cable 320 is wound around the first outrigger wheel 610.

[0047] Specifically, the first outrigger wheel 610 is rotatably disposed on the driving end of the driving assembly 600. One end of the first cable 320 is connected to the bottom of the first boom 100. The other end of the first cable 320 first extends in the direction close to the first outrigger wheel 610 and is wound around the first outrigger wheel 610, and then changes direction through the first outrigger wheel 610 and extends in the direction close to the bottom of the third boom 300 and is connected to the bottom of the third boom 300, thereby realizing the arrangement of the first cable 320, so that a part of the first cable 320 is located between the bottom of the first boom 100 and the first outrigger wheel 610, and another part of the first cable 320 is located between the first outrigger wheel 610 and the bottom of the third boom 300. Thus, driving the first outrigger wheel 610 to move by the driving end of the driving assembly 600 can change the distance between the bottom of the first boom 100 and the first outrigger wheel 610, and correspondingly change the length of the first cable 320 located between the bottom of the first boom 100 and the first outrigger wheel 610, and further change the length of the first cable 320 located between the first outrigger wheel 610 and the bottom of the third boom 300 together, realizing the relative movement between the two ends of the first cable 320, and thereby driving the change of the distance between the first outrigger wheel 610 and the bottom of the third boom 300 by changing the length of the first cable 320 located between the first outrigger wheel 610 and the bottom of the third boom 300, so as to realize the lifting operation of the third boom 300. By sharing the acting force, the stability and safety during the lifting process are improved.

[0048] In some specific embodiments of the present invention, referring to Figure 1 and Figure 2 , a plurality of first outrigger wheels 610 are provided, and the plurality of first outriggers are symmetrically arranged on both sides of the driving end of the driving assembly 600. A plurality of first cables 320 are provided, and the plurality of first cables 320 are arranged in one-to-one correspondence with the plurality of first outrigger wheels 610. Specifically, the plurality of first outrigger wheels 610 are symmetrically arranged on both sides of the driving end of the driving assembly 600, and the plurality of first outrigger wheels 610 are arranged in one-to-one correspondence with the plurality of first cables 320, so as to further share the acting force and improve the stability and safety during the lifting process.

[0049] In some specific embodiments of the present invention, referring to Figure 1 and Figure 2, further comprising: a fourth arm 400 and a fifth arm 500. The fourth arm 400 is coaxially and slidably inserted into the third arm 300. A second cable 420 is disposed between the fourth arm 400 and the second arm 200, and the second cable 420 is movably connected to the third arm 300 so that the two ends of the second cable 420 can be driven to move relatively by the third arm 300. The fifth arm 500 is coaxially and slidably inserted into the fourth arm 400. A third cable 510 is disposed between the fifth arm 500 and the third arm 300, and the third cable 510 is movably connected to the fourth arm 400 so that the two ends of the third cable 510 can be driven to move relatively by the fourth arm 400.

[0050] Specifically, the fourth arm 400 is coaxially and slidably inserted into the third arm 300 at one end of the third arm 300 away from the second arm 200, and the fifth arm 500 is coaxially and slidably inserted into the fourth arm 400 at one end of the fourth arm 400 away from the third arm 300. Among them, a second cable 420 is connected between the fourth arm 400 and the second arm 200. One end of the second cable 420 is connected to the second arm 200, and the other end of the second cable 420 movably passes through the third arm 300 and is connected to the fourth arm 400, so that a part of the second cable 420 is located between the second arm 200 and the third arm 300, and another part of the second cable 420 is located between the third arm 300 and the fourth arm 400. Thus, by moving the third arm 300, the distance between the second arm 200 and the third arm 300 can be changed, and the length of the second cable 420 located between the second arm 200 and the third arm 300 can be correspondingly changed. Furthermore, the length of the second cable 420 located between the third arm 300 and the fourth arm 400 can be changed together, realizing the relative movement between the two ends of the second cable 420. In this way, by changing the length of the second cable 420 located between the third arm 300 and the fourth arm 400, the distance between the third arm 300 and the fourth arm 400 can be driven to change, so as to realize the lifting operation of the fourth arm 400. A third cable 510 is connected between the fifth arm 500 and the third arm 300. One end of the third cable 510 is connected to the third arm 300, and the other end of the third cable 510 movably passes through the fourth arm 400 and is connected to the fifth arm 500, so that a part of the third cable 510 is located between the third arm 300 and the fourth arm 400, and another part of the third cable 510 is located between the fourth arm 400 and the fifth arm 500. Thus, by moving the fourth arm 400, the distance between the third arm 300 and the fourth arm 400 can be changed, and the length of the third cable 510 located between the third arm 300 and the fourth arm 400 can be correspondingly changed. Furthermore, the length of the third cable 510 located between the fourth arm 400 and the fifth arm 500 can be changed together, realizing the relative movement between the two ends of the third cable 510. In this way, by changing the length of the third cable 510 located between the fourth arm 400 and the fifth arm 500, the distance between the fourth arm 400 and the fifth arm 500 can be driven to change, so as to realize the lifting operation of the fifth arm 500. By further adding the fourth arm 400 and the fifth arm 500, the total lifting range is increased. And during lifting, since the force generated by the fourth arm 400 acts on the second cable 420, and the force generated by the fifth arm 500 acts on the third cable 510, while increasing the liftable range, the sharing of the force is ensured, avoiding being easily affected by external environmental factors, and ensuring the stability and safety during the lifting process.Meanwhile, through the modular connection between the fourth arm 400, the fifth arm 500 and the first arm 100, the second arm 200, and the third arm 300, it is convenient for installation and disassembly, shortens the operation preparation time, improves the operation efficiency, simplifies the maintenance process, and reduces the maintenance cost.

One end of the second cable 420 is connected to the bottom of the second arm 200. The other end of the second cable 420 first extends in the direction close to the second outrigger wheel 310 and is wound around the second outrigger wheel 310, and then changes direction through the second outrigger wheel 310 and extends in the direction close to the bottom of the fourth arm 400 and is connected to the bottom of the fourth arm 400, so as to realize the setting of the second cable 420, so that a part of the second cable 420 is located between the bottom of the second arm 200 and the second outrigger wheel 310, and another part of the second cable 420 is located between the second outrigger wheel 310 and the bottom of the fourth arm 400. Thus, by driving the second outrigger wheel 310 to move through the third arm 300, the distance between the bottom of the second arm 200 and the second outrigger wheel 310 can be changed, and the length of the second cable 420 located between the bottom of the second arm 200 and the second outrigger wheel 310 can be correspondingly changed, and further the length of the second cable 420 located between the second outrigger wheel 310 and the bottom of the fourth arm 400 can be changed together, realizing the relative movement between the two ends of the second cable 420. In this way, by changing the length of the second cable 420 located between the second outrigger wheel 310 and the bottom of the fourth arm 400, the distance between the second outrigger wheel 310 and the bottom of the fourth arm 400 can be changed, so as to realize the lifting operation of the fourth arm 400. By sharing the acting force, the stability and safety during the lifting process are improved.

[0053] The third outrigger wheel 410 is rotatably arranged on the inner wall of one end of the fourth outrigger 400 away from the third outrigger 300.

Thus, driving the third outrigger wheel 410 to move by the fourth outrigger 400 can change the distance between the bottom of the third outrigger 300 and the third outrigger wheel 410, and correspondingly change the length of the third cable 510 located between the bottom of the third outrigger 300 and the third outrigger wheel 410, and further change the length of the third cable 510 located between the third outrigger wheel 410 and the bottom of the fifth outrigger 500 together, realizing the relative movement between the two ends of the third cable 510. In this way, by changing the length of the third cable 510 located between the third outrigger wheel 410 and the bottom of the fifth outrigger 500, the distance between the third outrigger wheel 410 and the bottom of the fifth outrigger 500 is changed, so as to realize the lifting operation of the fifth outrigger 500.
