Description

Technical Field

[0001] The present invention relates to the field of electric power equipment construction, and in particular to a narrow base angle steel cable terminal tower construction device. Background Art

[0002] The narrow base angle steel cable terminal tower is a cable terminal tower that uses angle steel as the main construction material. This type of cable terminal tower adopts the method of segmented assembly and splicing to build the main tower body. After the tower body of the cable terminal tower is built, the cross arms of different installation heights need to be assembled and then hoisted and spliced ​​in sequence.

[0003] The cross arms of narrow-base angle steel cable terminal towers are mostly assembled by splicing at the construction site. The cross arms are composed of cross bars and diagonal bars, and are connected to the reinforcing angle steel with connectors. The installed cross arms are similar to sideways vertebral structures. The tower body is built in a wide-bottom-narrow-top manner, so that there is an inclination angle between the diagonal bars of the cross arms, and the cross arms and diagonal bars have a certain inclination angle relative to the center position of the cross arms. The sizes of cross arms at different installation heights are different. The structure of the cross arms makes their splicing more complicated. The cross arms are generally spliced ​​by manually supporting the cross bars and diagonal bars and positioning them with connectors.

[0004] There are the following problems with the splicing of the crossarms on the cable terminal tower: the deflection angles of the horizontal bars and diagonal bars on the crossarms cannot be accurately adjusted, and the horizontal bars and diagonal bars cannot be clamped and locked, making it impossible to connect them quickly. When the horizontal bars and diagonal bars of the crossarms deviate from their positions, they cannot be adjusted, resulting in misalignment when the crossarms are connected, affecting the splicing effect of the crossarms; the positions of the horizontal bars and diagonal bars are asymmetrical, resulting in the inability to connect the reinforcing angle steel of the crossarms in the later stage.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention locks the crossbar and the diagonal bar of the crossarm on the cable terminal tower separately, and quickly adjusts the position and deflection angle of the crossbar and the diagonal bar respectively, so that the crossarm can be accurately docked, which facilitates the rapid connection of the connecting parts on the crossarm and the reinforcing angle steel.

In addition, the present invention can also fine-tune the position of the connection between the crossbar and the diagonal bar, so that the crossbar and the diagonal bar can be quickly and accurately docked.

[0020] 2. The present invention positions and locks cross bars of different deflection angles through the cross bar locking part. The cross bar locking part can be driven to move synchronously inward and outward through the distance adjustment component. The rotating plate can adjust the angle so that the cross bar is at the required deflection angle. The locking card locks the cross bar on the assembly base under the action of the elastic telescopic rod.

[0021] 3. The present invention positions and locks diagonal rods of different inclination angles through the diagonal rod locking part, and adjusts the distance and inclination angle between the diagonal rod and the cross bar on the cross arm through the adjustment part, and then the spacing of the diagonal rod locking part can be adjusted through the retractable part. Thereafter, the diagonal rod locking part adjusts the inclination angle of the diagonal rod, and one side of the diagonal rod is clamped and locked by the locking clamp plate and the diagonal rod rotating plate.

[0022] 4. The magnet block of the present invention can absorb the side of the horizontal bar or the diagonal bar, increase the locking stability of the horizontal bar or the diagonal bar, and at the same time prevent the horizontal bar or the diagonal bar from being inserted into place and causing deviation in its installation. The installation surfaces of the horizontal bar and the diagonal bar are both facing outward, which facilitates the installation of the horizontal bar and the diagonal bar.

[0023] 5. The vertical alignment plate of the present invention aligns the ends of the horizontal bar and the diagonal bar that are close to each other, preventing the left and right positions of the horizontal bar and the diagonal bar from deviating, and increasing the connection accuracy between the horizontal bar and the diagonal bar. When there is a left and right deviation between the horizontal bar and the diagonal bar, the position of the push plate can be adjusted by rotating the alignment stud, so that the horizontal bar and the diagonal bar can be accurately connected.

[0024] 6. When the cross bar and the diagonal bar on the cross arm are steel pipes, the arc-shaped grooves of the diagonal bar locking card plate and the diagonal bar rotating plate can lock their positions, and the arc-shaped grooves on the diagonal bar locking card plate and the diagonal bar rotating plate close to their chamfered positions can make the installation point of the steel pipe extend to the outside of the diagonal bar locking card plate.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0036] See Figures 1-8The cam 2 is a kind of cam 2 that is used to move the cables and put them in a fixed position so that the cables can be put in a fixed position at a certain position so that the cables can be put in a fixed position at a certain position. During construction, the tower body foundation needs to be spliced. After the tower body foundation is spliced, the cross arms on the cable terminal tower are spliced ​​and assembled, and then they are lifted to the installation position by means of a boom hoisting method, and finally the assembled cross arms are manually locked and connected to the tower body of the cable terminal tower. The present invention can assemble and splice the cross arms of cable terminal towers of different sizes. Specifically, the cross bars of the cross arms are first locked by the cross bar locking part 2, and the diagonal bars of the cross arms are locked by the diagonal bar locking part 5, and the cross bar locking part 2 and the diagonal bar locking part 5 can respectively adjust the angles of the cross bars and the diagonal bars so that they are in a suitable assembly position and angle, and finally the cross bars and the diagonal bars are connected by connecting parts. After the connection is completed, the cross bars and the diagonal bars are reinforced for the installation of angle steel. It should be noted that there will be corresponding inclination angles between the diagonal bars on the cross arms and the cross arms, and the cross bars and the diagonal bars have a certain deflection angle with the middle part of the cross arms.

[0037] The crossbar locking portion 2 includes a locking support plate 21 that slides with the assembled base plate 1. The locking support plate 21 is installed with a rotating plate 22 at one end of the side away from the distance adjusting component 3 by a rotating cooperation method. The rotating plate 22 is provided with an arc rod 23 at one end away from its hinge. When specifically set, a scale mark can be set on the arc rod 23 to timely see the angle of the rotating plate 22. The axis of the arc structure of the arc rod 23 coincides with the center line of the rotating connection of the rotating plate 22. The middle part of the arc rod 23 slides with the locking support plate 21. The top of the locking support plate 21 is connected with a clamping bolt 24 by a threaded cooperation method. The lower end of the clamping bolt 24 rests on the upper side of the arc rod 23. Elastic telescopic rods 25 are symmetrically provided on the rotating plate 22. The top of the elastic telescopic rod 25 is equipped with a locking card plate 26. 26 is an L-shaped structure. The vertical section of the locking card plate 26 cooperates with the assembly base plate 1 to lock the cross bar. The cross bar locking part 2 can position and lock cross bars with different deflection angles. First, adjust the locking support plate 21 to the appropriate position through the distance adjustment component 3, loosen the clamping bolt 24, and rotate the rotating plate 22 to the corresponding angle according to the deflection angle of the cross bar. Then, tighten the clamping bolt 24 so that its lower end rests on the upper end of the arc rod 23, so that the angle of the cross bar is locked. Then, pull the locking card plate 26 upward and insert one side of the cross bar into the lower end of the locking card plate 26, and the other side of the cross bar is attached to the side of the locking card plate 26. Finally, remove the external force, and the locking card plate 26 locks the cross bar on the assembly base plate 1 under the action of the elastic telescopic rod 25. The above-mentioned locking method of the cross bar makes the installation surface of the cross bar arranged outward.

[0038] The locking plate 21 is fixed to the upper and lower parts of the lock plate 21, and the locking plate 21 is fixed to the upper and lower parts of the lock plate 21.

[0039] The diagonal rod locking portion 5 includes a diagonal rod locking support plate 51, a diagonal rod rotating plate 52, a diagonal plate arc rod 53, a diagonal plate clamping bolt 54, a diagonal plate elastic telescopic rod 55 and a diagonal rod locking clamping plate 56. The diagonal rod locking portion 5 has the same locking form as the cross bar locking portion 2. The diagonal rod locking clamping plate 56 is a flat plate structure. The diagonal rod locking clamping plate 56 cooperates with the diagonal rod rotating plate 52 to lock the diagonal rod. When the diagonal rod is locked, one side of the diagonal rod is clamped and locked by the diagonal rod locking clamping plate 56 and the diagonal rod rotating plate 52, and the other side of the diagonal rod is attached to the outer side of the diagonal rod rotating plate 52. The above locking method can make the installation surface of the diagonal rod face outward, which is convenient for strengthening the connection of the installation surface of the diagonal rod and the installation surface of the cross bar with the angle steel.

[0040] When the blocking block 58 on the tilting plate 52 abuts against the tilting rod locking support plate 51, the tilting rod rotating plate 52 is in a straight state. Similarly, when the blocking block 58 on the rotating plate 22 abuts against the locking support plate 21, the rotating plate 22 is in a straight state, which facilitates the splicing and locking of the cross bar and the tilting rod without a deflection angle of the present invention.

[0041] The opposite ends of the inclined rod locking card plate 56 and the inclined rod rotating plate 52 away from the inclined support plate 4 are both provided with chamfers. The setting of the chamfers makes it unnecessary to manually lift the inclined rod locking card plate 56. The inclined rod can be directly inserted between the inclined rod locking card plate 56 and the inclined rod rotating plate 52. The bottom of the locking card plate 26 is provided with a chamfer. The function of the chamfer of the locking card plate 26 is the same as that of the inclined rod locking card plate 56. The opposite sides of the inclined rod locking card plate 56 and the inclined rod rotating plate 52 near their chamfered positions are both provided with arc grooves. The locking card plate 26 An arc-shaped groove is also provided at the bottom near its chamfered position. The cross bars and diagonal bars on the cross arms of the angle steel cable terminal tower are mostly angle steels, and a small part is steel pipes. When the cross bars and diagonal bars are steel pipes, the arc-shaped grooves of the diagonal bar locking card plate 56 and the diagonal bar rotating plate 52 can lock their positions, and the arc-shaped grooves on the diagonal bar locking card plate 56 and the diagonal bar rotating plate 52 near their chamfered positions can make the installation point of the steel pipe extend to the outside of the diagonal bar locking card plate 56. Similarly, the locking card plate 26 can also position and lock the steel pipe-type cross bars.

[0042] The side of the diagonal rod rotating plate 52 away from the diagonal support plate 4 and the side of the locking clamping plate 26 away from the distance adjustment component 3 are both embedded with magnet blocks 57. The magnet blocks 57 can absorb the side of the cross bar or the diagonal rod to increase the stability of the locking of the cross bar or the diagonal rod, and at the same time prevent the cross bar or the diagonal rod from being not inserted into place, causing deviation in its installation.

[0043] The adjustment component includes a height adjustment rod 41 installed on the top of the assembly base plate 1, and a height support plate 42 is installed on the upper side of the height adjustment rod 41. The top of the height support plate 42 is installed on the bottom of the inclined support plate 4 through a hinge. An angle bracket 43 is provided on one side of the height support plate 42, and an angle stud 44 is installed on the angle bracket 43 by threaded fitting. The top of the angle stud 44 is rotatably connected to a connecting plate 45, and the upper side of the connecting plate 45 is connected to a T-shaped slider 46 through a hinge. The bottom of the inclined support plate 4 is provided with a T-shaped slide groove that cooperates with the T-shaped slider 46. The height adjustment rod 41 can adjust the height of the inclined support plate 4, and the inclination angle of the inclined support plate 4 can be adjusted by rotating the angle stud 44.

[0044] The middle part of the inclined support plate 4 is a hollow structure, and the side walls of the inclined support plate 4 are symmetrically slidably connected with a retracting rod 47. One end of the retracting rod 47 outside the inclined support plate 4 is connected to the side of the inclined rod locking support plate 51. The retracting component 6 performs synchronous retraction and adjustment on the retracting rod 47. A scale mark can be set on the retracting rod 47 to facilitate intuitive viewing of the position of the retracting component 6.

[0045] The retractable component 6 includes a retractable rotating rod 61 arranged in the hollow structure of the oblique support plate 4, one end of the retractable rotating rod 61 is rotatably connected to the side wall of the oblique support plate 4, and the other end of the retractable rotating rod 61 is located on the outside of the oblique support plate 4, and the retractable rotating rod 61 is located in the hollow structure of the oblique support plate 4 and is provided with an external thread. The external thread of the retractable rotating rod 61 is screwed with a retractable slider 62 that is slidably connected to the inner wall of the oblique support plate 4, and the side surfaces of the retractable slider 62 are respectively connected to the retractable rod 47 through hinges with synchronous adjustment rods 63. The retractable rotating rod 61 is rotated to drive the retractable slider 62 to slide, and the retractable slider 62 drives the retractable rod 47 to move synchronously inward and outward through the synchronous adjustment rod 63, so that the oblique rod locking part 5 can perform synchronous inward and outward position adjustment.

[0046] The assembly base plate 1 is provided with a sliding adjustment rod 11 on the side of the downward inclined inclined support plate 4 corresponding to the assembly base plate 1. The sliding adjustment rod 11 can be telescopically adjusted on the assembly base plate 1. The end of the sliding adjustment rod 11 away from the assembly base plate 1 is connected to a vertical alignment plate 12 for aligning the horizontal bar and the diagonal bar. The vertical alignment plate 12 aligns the ends of the horizontal bar and the diagonal bar that are close to each other to prevent the left and right positions of the horizontal bar and the diagonal bar from deviating, thereby increasing the connection accuracy between the horizontal bar and the diagonal bar.

[0047] The vertical alignment plate 12 is a Z-shaped structure, and a pushing plate 13 is provided above the transverse section of the vertical alignment plate 12. The middle part of the pushing plate 13 is rotatably connected with an alignment stud 14, and the alignment stud 14 is threadedly connected to the upper end of the vertical alignment plate 12. Guide columns are symmetrically provided on both sides of the alignment stud 14, and the guide columns are connected to the pushing plate 13, and the pushing plate 13 is slidably connected to the vertical alignment plate 12; when the oblique rod is against the pushing plate 13, its installation position and the cross bar have a left and right deviation, the position of the pushing plate 13 can be adjusted by rotating the alignment stud 14, so that the cross bar and the oblique rod can be accurately docked; an adjusting vertical plate 15 is vertically provided in the pushing plate 13, and the adjusting vertical plate 15 and the pushing plate 13 are frictionally matched. When the height of the cross bar is high, the adjusting vertical plate 15 can be pulled upward so that the pushing plate 13 will not drive the cross bar to move when adjusting the left and right position.

[0048] In addition, the present invention also proposes a method for constructing a narrow base angle steel cable terminal tower, the steps of which are as follows:

[0049] The first step is to level the site where the cable terminal tower will be laid and excavate the foundation of the cable terminal tower.

Then, the tower legs are installed on the foundation of the cable terminal tower and the tower body at the bottom of the terminal tower is aligned and installed in sequence.

[0051] The third step is to hoist the mast to the appropriate height, splice each section of the terminal tower at the construction site, and hoist each spliced ​​tower section to the appropriate height using the mast. Then, splice and build the cable terminal towers one by one.

[0052] The fourth step is to assemble the cross arms of the cable terminal tower at the construction site after the tower body is installed.

After that, the diagonal support plate 4 is adjusted to the appropriate height and angle by adjusting the components;

[0054] S2, according to the deflection angle of the crossbar and the diagonal rod of the crossarm, the inclination angle of the rotating plate 22 and the diagonal rod rotating plate 52 is rotated and adjusted; then one side of the crossbar is inserted into the lower end of the locking card 26, and the other side of the crossbar is attached to the magnet block 57 embedded on the side of the locking card 26.

[0055] S3, lock the left end of the horizontal bar and the diagonal bar with the connector, then lock the right end with the connector, and then install the reinforcing angle steels on the front and rear sides of the horizontal bar and the diagonal bar in sequence to complete the connection and locking of the crossarm main body position;

[0056] S4, control the locking support plate 21 and the diagonal rod locking support plate 51 to move inward so that the cross arm can be removed, and the angle steels at other positions of the cross arm are installed, thereby completing the overall splicing of the cross arm;
