Description

Technical Field

[0002] At present, in the process of construction, due to tight schedule or engineering needs, it is often necessary to continue construction at night. The use of lighting devices is indispensable for night construction. However, the common lighting devices currently use temporary pulling wires and then hanging ordinary light sources for lighting.

[0003] For example, spiral cables are sometimes used for pulling wires, but spiral cables are elastic. When the light pole is raised, the spiral cable is stretched. The higher the lighthouse is raised, the greater the elasticity of the spiral cable, which requires more effort from the user. The spiral cable is always in a constant state of tension during use. After a period of use, the elastic force is prone to attenuation. When the light pole is retracted, the spiral cable cannot rebound effectively. When in a free state, the length of the spiral cable increases, making it easy for it to rub against other parts / the ground or become a tangled mess, posing certain safety risks.

[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] Reference below Figure 1-Figure 8 The cable installation structure 100 according to the embodiment of the utility model is described. When the columns are relatively extended, the cable 6 and the drag chain 4 can be extended. When the columns are contracted, the cable 6 and the drag chain 4 can be contracted. The cable 6 has no spiral tension and can be raised and lowered easily without the problem of elastic force attenuation.

[0033] Reference below Figure 1-Figure 8 The cable installation structure 100 according to an embodiment of the present utility model is described, including: a multi-section column, a drag chain 4 and a cable 6.

[0034] Among them, the multi-section columns are arranged to be sleeved in sequence along the length direction, and the two adjacent sections of the columns are retractable in the length direction, and a drag chain 4 is arranged between the two adjacent sections of the columns, one end of the drag chain 4 is connected to one of the two adjacent sections of the columns and the other end of the drag chain 4 is connected to the other section of the column, and the drag chain 4 is provided with a threading hole. The drag chain 4 has at least one section, and when the drag chain 4 has one section, the column has two sections, and when the drag chain 4 has multiple sections, the column has more than three sections. The cable 6 is arranged through the threading hole of one section of the drag chain or is arranged through the threading holes of multiple sections of the drag chain 4 in sequence.

[0035] In practice, the multi-section columns are arranged to be arranged in sequence along the length direction, and the length direction between two adjacent columns is retractable. The overall length of the multi-section columns can be adjusted according to actual conditions during application, and a drag chain 4 is connected between two adjacent columns, wherein one end of the drag chain 4 can be connected to the outer wall of one column and the other end is connected to the inner wall of the other column. The drag chain 4 can also be connected to the inner wall of one column at one end and the inner wall of the other column at the other end. It is only necessary for the drag chain 4 to be connected between the two columns and to be able to retract along with the retraction of the adjacent columns, so that the cable can meet various length requirements when in use, and the cable can be retracted when not in use due to the retraction action of the column.

[0036] Specifically, an opening may be provided at the end of each column, referring to Figure 2 As shown, that is, an open opening is provided at the upper end of each column section, so as to facilitate the telescopic installation between multiple columns; moreover, when a drag chain 4 is provided between two adjacent columns, the ordinary cable 6 can pass through one drag chain 4 and then continue to bend upwards, extend along the end opening of each column section and pass through the inside of the other drag chain 4; of course, it is also possible to make the side wall of the column connected to the two adjacent drag chains 4 partially penetrated, and it is also possible to meet the requirement that the cable 6 extends out of one drag chain 4 and passes through the side wall of the column through the inside of the other drag chain 4, so that the cable 6 passes through multiple drag chains 4, which can not only enable the drag chain 4 to protect the cable 6 externally, but also drive each drag chain 4 to move when the column is extended and retracted, thereby causing the cable 6 to contract or extend; of course, when there is only one drag chain 4, the cable 6 passes through the inside of the drag chain 4 along one column and then extends out of the other column, which can also realize the contraction or extension of the cable 6 when the two columns are contracted or extended; moreover, an activity space is provided between the two adjacent columns, that is Figure 2 The space between the outer walls of two adjacent columns allows the drag chain 4 to shrink or extend within the movable space when one column shrinks relative to the other column, so that the drag chain 4 can shrink or extend more smoothly.

[0037] Therefore, the cable 6 of the embodiment of the utility model drives the movement of the drag chain 4 and then drives the movement of the cable 6 during the movement of the column. There is no spiral tension of the traditional spiral cable 6, and the lifting and lowering are easy and free. Moreover, the cable 6 can be an ordinary cable, which is easier to purchase. The cable 6 extends and retracts with the extension and retraction of the column, which increases the neatness of the cable 6 when it is retracted, and it will not be entangled with other structures or parts.

[0038] In some embodiments, each section of the drag chain 4 includes a first connection end 42 and a second connection end 41, the first connection end 42 of the drag chain 4 is connected to the outer peripheral wall of the inner section of the two adjacent sections of the column, and the second connection end 41 of the drag chain 4 is connected to the inner peripheral wall of the outer section of the two adjacent sections of the column.

[0039] In practice, the first connection end 42 of each drag chain 4 is connected to the outer wall of a column and the second connection end 41 is connected to the inner wall of an adjacent column. In addition, other parts of each drag chain 4 can be in contact with the outer wall of the column, so that the column can drive the drag chain 4 to move when it moves, and each drag chain 4 is connected between two adjacent columns. When the two adjacent columns are extended or retracted, the drag chain 4 can move along the length direction of the column, and the column can drive the drag chain 4 to extend or contract along the length direction of the column more smoothly.

[0040] In addition, assuming that one end of each drag chain 4 is connected to the inner wall of a column section and the other end is connected to the inner wall of another adjacent column section, it is necessary to open the upper end of the column with the larger diameter among the two columns to enter the interior of the column. This will cause the drag chain 4 to bend at the end of the column and extend along the outside of the column with the larger diameter to the inside of the column, which will cause the telescopic movement between the columns to be not smooth, and each drag chain 4 is bent at the end opening of the column, with poor uniformity. Therefore, in the embodiment of the utility model, the first connecting end 42 of each drag chain 4 is connected to the outer wall of one column section and the second connecting end 41 is connected to the inner wall of another column section. When the column shrinks, all the drag chains 4 can basically shrink inside the column, that is, the part of the cable 6 extending into the drag chain 4 also shrinks inside the column. Figure 4 As shown, the uniformity is higher and the shrinkage is smoother.

[0041] In some embodiments, the first connecting end 42 is provided with a first connecting plate, the first connecting plate is provided with a first connecting hole 421, and the first connecting plate is connected to the corresponding column through a first connecting member 7 passing through the first connecting hole 421; and / or, the second connecting end 41 includes a second connecting plate, the second connecting plate is provided with a second connecting hole 411, and the second connecting plate is connected to the corresponding column through a second connecting member 8 passing through the second connecting hole 411.

[0042] Reference Figure 8 As shown, the first connecting plate is connected to one end of the drag chain 4 and the second connecting plate is connected to the other end of the drag chain 4, the first connecting plate is provided with a first connecting hole 421, and the second connecting plate is provided with a second connecting hole 411, and the first connecting plate is connected to the column through the first connecting member 7, that is, the first connecting end 42 of the drag chain 4 is connected to the outer wall of a section of the column, and the second connecting plate is connected to the inner wall of another adjacent column through the second connecting member 8, that is, the second connecting end 41 of the drag chain 4 is connected to the inner wall of a section of the column. By providing the first connecting plate and the second connecting plate, the connection area between the drag chain 4 and the column is increased, and it is also convenient to connect the drag chain 4 to the column through the connecting member to achieve the fixation of the two ends of the drag chain 4.

[0043] In addition, the first connection hole 421 has two sections and is spaced apart on the first connection plate, and the second connection hole 411 also has two sections and is spaced apart on the second connection plate, which can further enhance the stability and reliability of the connection between the two ends of the drag chain 4 and the column.

[0044] In some embodiments, the first connecting plate of each drag chain 4 and the second connecting plate of an adjacent drag chain 4 are relatively distributed on the inner side and the outer side of the commonly connected column.

[0045] Combination Figure 3 and Figure 8As shown, in two adjacent sections of the drag chain 4, the first connecting plate of one section of the drag chain 4 is opposite to the second connecting plate of the other section of the drag chain 4, that is, the second connecting end 41 of one section of the drag chain 4 is located on the inner wall of the column and the first connecting end 42 of the other section of the drag chain 4 is located on the outer wall of the column, so that the drag chain 4 is more convenient to pass through the inside of one section of the drag chain 4 through the commonly connected column to the inside of the other section of the drag chain 4, and when the first connecting plate of one section of the drag chain 4 and the second connecting plate of the other section of the drag chain 4 are opposite to each other on both sides of the same column, the cable 6 can be extended from the drag chain 4 inside one column to the drag chain 4 outside the column.

[0046] In some embodiments, a column located between two adjacent sections of the drag chain 4 is provided with a through hole 5 , and the cable 6 is suitable for being passed through the through hole 5 to be respectively passed through the threading channels of the two adjacent sections of the drag chain 4 .

[0047] Reference Figure 3 As shown, the through hole 5 is opened in the side wall of the column and penetrates in the radial direction of the column. When the cable 6 is penetrated into one section of the drag chain 4, the cable 6 continues to extend into the other section of the drag chain 4 through the through hole 5 of the column. The through hole 5 can be set closer to the two sections of the drag chain 4, which can reduce the penetration path of the cable 6 in the drag chain 4, and the through hole 5 is set on the column to which the second connection end 41 of one section of the drag chain 4 and the first connection end 42 of the other section of the drag chain 4 are commonly connected, so as to facilitate the cable 6 to pass through one section of the drag chain 4 from the inside of the column to the other section of the drag chain 4 outside the column, and the through hole 5 also has a limiting effect on the cable 6, so that the cable 6 can always move along the through hole 5 and in the up and down directions of the column, preventing the cable 6 from moving in multiple directions and causing the cable 6 to be uneven.

[0048] In some embodiments, the through hole 5 is located on the upper side of the column, and the through hole 5 is located at the top of the connection between the end of the drag chain 4 and the column. Figure 3 As shown, during installation, the cable can be passed through the column first, and then each section of the drag chain 4 is put on the cable, and the two ends of the drag chain 4 are fixed on the column. Figure 3 The cable 6 is arranged on the upper part of the column, and above the second connection end 41 of one drag chain 4 and above the first connection end 42 of the other drag chain 4, so that the cable 6 can form a curved structure between two adjacent drag chains 4. When the adjacent columns are extended, the cable 6 can have a certain force buffer when it is stretched by external force.

[0049] In practice, elastic components such as rubber rings can be provided at the through holes 5 to play a certain sealing role. At the same time, during the extension and retraction of the columns, the friction between the cable 6 and the through holes 5 of the columns can be reduced to protect the cable 6.

[0050] In some embodiments, the columns are each provided with a first end and a second end along the length direction, one end of the drag chain 4 is connected to the first end of one of the two adjacent columns, and the other end of the drag chain 4 is connected to the first end of the other of the two adjacent columns.

[0051] Reference Figure 2 and Figure 3 As shown, the first end refers to Figure 2 and Figure 3 The second end refers to Figure 2 and Figure 3 The lower end of the towline 4, that is, when the towline 4 is connected between two adjacent columns, the first connecting end 42 of each towline 4 is connected to the upper end of the outer wall of one column and the second connecting end 41 is connected to the upper end of the inner wall of another column. At this time, when the multiple columns are extended, that is, Figure 2 As shown, basically the entire drag chain 4 is exposed outside the column; and when the multiple columns are contracted, that is, as shown in Figure 4 As shown, the retracted cable 6 and the drag chain 4 are also basically located in the area above the middle position of each column section; and each column section has a certain retraction space, that is, the column needs to drive the drag chain 4 to retract when it retracts, and assuming that the position of the drag chain 4 is biased towards below the middle position of the column, it is possible that after the column retracts, the drag chain 4 and the cable 6 are not effectively retracted, or when the column is extended, the cable 6 and the drag chain 4 are still located inside the column, making it inconvenient to observe the contraction or extension status of the cable 6.

[0052] Thus, the first connection end 42 of the drag chain 4 is connected to the upper end of the outer wall of a column and the second connection end 41 is connected to the upper end of the inner wall of an adjacent column, leaving a certain contraction space for the drag chain 4 and the cable 6. At the same time, when the drag chain 4 and the cable 6 are extended, the drag chain 4 is exposed outside the external column as the internal column is stretched, which makes it easier to observe the contraction and extension state of the cable 6, so that the staff can more reasonably control the degree of stretching.

[0053] In some embodiments, the column has at least three sections, and the three adjacent sections of the at least three sections are respectively the first column 1, the second column 2 and the third column 3, and the second column 2 and the first column 1 are each provided with a through hole 5; the calibers of the first column 1 to the third column 3 decrease successively, a section of the drag chain 4 is connected between the inner wall of the first column 1 and the outer wall of the second column 2, and another section of the drag chain 4 is connected between the inner wall of the second column 2 and the outer wall of the third column 3, and the cable 6 passes through the drag chain 4 between the third column 3 and the second column 2 in sequence and enters the drag chain 4 between the second column 2 and the first column 1 through the through hole 5 of the second column 2, and continues from the drag chain 4 through the through hole 5 of the first column 1 to extend to the outside of the first column 1.

[0054] In practice, the columns are generally set to 5-8 sections, and the corresponding drag chain 4 can be set to 4-7 sections. If too many columns are set, the operation is more complicated. If too few columns are set, the cable length may not meet the requirements or the length of each section of the column may be long, which is inconvenient to store. The number of columns and drag chains 4 set in the embodiment of the utility model can meet the actual use length requirements of the cable while having a relatively simple structure.

[0055] In addition, in order to more easily illustrate the embodiment of the utility model, the column is set to three sections, such as Figure 5-7 As shown, at this time, the drag chain 4 is divided into two sections, the third column 3 can be stretched or contracted inside the second column 2, and the second column 2 can also be stretched or contracted inside the first column 1. The third column 3 does not need to be provided with a through hole 5. The cable 6 is directly passed through the drag chain 4 between the third column 3 and the second column 2, and one free end of the cable 6 extends along the outside of the third column 3 to the lighting lamp to be connected. After the cable 6 passes through the drag chain 4 between the second column 2 and the first column 1, the other free end of the cable 6 passes through the through hole 5 of the first column 1 and extends to the outside of the first column 1. In this way, the part of the cable 6 passing through the outside of the first column 1 can be used to connect to the power supply. By setting the first column 1, the second column 2 and the third column 3, the length requirement of the cable 6 extending with the extension of the column can be met, and at the same time, the setting of the drag chain 4 can be reduced, and the complexity of setting the entire cable installation structure 100 can be reduced. Exemplarily, the drag chain 4 is connected to the third column 3 by screws 7, and the drag chain 4 between the second column 2 and the first column 1 is connected by screws 7 and 8 respectively. Other fixed or detachable connection methods can also be used between the drag chain and the column.

[0056] In some embodiments, each drag chain 4 is formed by a plurality of links hinged to each other, and each link is provided with a through hole for the cable 6 to pass through. When adjacent columns are extended or retracted, the contact length between the drag chain 4 and the adjacent columns changes and the total length remains unchanged.

[0057] That is to say, one end of the drag chain 4 is fixedly connected to the outer wall of a column, and the other end is fixedly connected to the inner wall of another column. When the drag chain 4 expands and contracts with the column, the total length of the drag chain 4 always remains unchanged, but the contact area with the adjacent column changes. By setting the drag chain 4 in this way, the drag chain 4 has better strength and long service life.

[0058] Of course, the drag chain 4 can also be set to be flexibly deformed, and the cable 6 adopts an ordinary cable, that is, the drag chain 4 is softer at this time. In the process of the ordinary cable 6 driving the drag chain 4 to move, the contact surface between the drag chain 4 and the adjacent columns at other positions except the two ends changes, and it can also solve the problem of deformation of the spiral cable 6 caused by the large elastic force when the traditional spiral cable 6 is stretched, and the problem of easy messiness.

[0059] The utility model embodiment also discloses a mobile light truck, including a lamp, a power supply and the above-mentioned cable installation structure 100, the lamp is connected to one end of the cable 6, and the other end of the cable 6 is connected to the power supply. When the columns are relatively extended, the cable 6 and the drag chain 4 can be extended, and when the columns are contracted, the cable 6 and the drag chain 4 can be contracted. The cable 6 has no spiral tension and can be raised and lowered easily. There is no problem of elastic force attenuation, which increases the service life of the cable 6, thereby reducing the frequency of replacing the cable 6 of the mobile light truck and improving the lighting experience of the mobile light truck.
