Description

Technical Field

[0001] This invention relates to the field of power engineering construction technology, specifically a device for installing and fixing angle steel inserted into power transmission lines. Background Technology

[0002] In the construction of transmission line tower foundations, insertable angle steel is a common component connecting the foundation and the tower. It needs to be pre-embedded in the concrete during foundation construction. Before pouring the concrete foundation, the insertable angle steel is pre-fixed in the concrete foundation reinforcement. The positioning and alignment of the insertable angle steel is the core process and key technical control point of foundation construction. If the positioning deviates from the permissible error, it will lead to difficulties in tower erection or even make it impossible to erect.

[0003] However, in practical applications, the support structure of existing angle steel installation and fixing devices for transmission lines is mostly an integrated design with a fixed pole length. This not only makes it impossible to flexibly adjust the support height and spacing according to the actual working conditions of the construction site, resulting in poor adaptability, but also leads to a large overall size of the device due to the fixed pole length, occupying a lot of space during storage and transportation, and making it inconvenient to handle. At the same time, the clamping and fixing structure of the device lacks an adjustable design, and the clamping spacing and contact surface cannot flexibly adapt to angle steel of different specifications and sizes, making it difficult to achieve stable and firm clamping and fixing of angle steel of different sizes. This seriously affects the versatility of the device and the actual construction effect, and cannot meet the diverse needs of construction site operations. Summary of the Invention

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art.

[0020] Example 1 Please refer to Figures 1 to 8As shown, a power transmission line insertion angle steel installation and fixing device includes an L-shaped plate 1, which is an isosceles right-angle plate. A surrounding plate 2 is provided on one side of the L-shaped plate 1. T-shaped clamping plates 3 are integrally formed at both ends of the surrounding plate 2. T-shaped slots 4 that are adapted to the T-shaped clamping plates 3 are provided at the top of both ends of the L-shaped plate 1. A locking component 5 for limiting the T-shaped clamping plates 3 is provided on the outer side of the L-shaped plate 1. An abutment mechanism 6 is provided on the surrounding plate 2. Connecting seats 7 are hinged to both outer sides of the L-shaped plate 1. Adjustable support legs 8 are connected to the connecting seats 7. An L-shaped extension frame 9 is fixedly connected to the bottom of the L-shaped plate 1. Clamping and fixing mechanisms 10 for fixing the adjustable support legs 8 are provided on both outer sides of the L-shaped extension frame 9.

[0021] Those skilled in the art will understand that during construction, the T-shaped clamps 3 at both ends of the enclosure 2 are first inserted into the T-shaped slots 4 at the top of both ends of the L-shaped plate 1. The T-shaped clamps 3 are then fixed by the locking component 5, so that the enclosure 2 and the L-shaped plate 1 enclose each other to form an angle steel fixing cavity. The power transmission line is then inserted into the angle steel and placed into the fixing cavity. The angle steel is then pressed and fixed by the abutment mechanism 6. At the same time, the adjustable support leg 8 is connected to the connecting seat 7 hinged to the outer side of the L-shaped plate 1 to provide stable support for the device. The clamping and fixing mechanism 10 on the L-shaped extension frame 9 can clamp and fix the adjustable support leg 8. At the same time, the fixing function of the clamping and fixing mechanism 10 on the adjustable support leg 8 can retract the support leg during device transportation, greatly reducing the device volume and improving transportation convenience.

[0022] Example 2 Furthermore, the bottom of both side frames of the L-shaped extension frame 9 are fixedly connected with plumb hooks 11.

[0023] Those skilled in the art will understand that when the device positions and fixes the inserted angle steel, a plumb line can be suspended on the plumb line hook 11. The verticality characteristics of the plumb line can be used to accurately calibrate the verticality and horizontality of the L-shaped plate 1, the enclosure plate 2 and the inserted angle steel. The addition of this structure does not require additional calibration equipment and is directly integrated into the device body. It is simple and convenient to operate and can effectively improve the positioning and alignment accuracy of the inserted angle steel. It can avoid the problem of difficulty or even inability to assemble the tower due to the positioning deviation of the angle steel, and ensure the overall quality of the construction of the transmission line tower foundation.

[0024] Example 3 Furthermore, the locking assembly 5 includes a housing 501 fixedly connected to the outside of the L-shaped plate 1. A first slider 502 is slidably connected inside the housing 501. A locking block 503 is fixedly connected to the side of the first slider 502 near the T-shaped plate 3. A locking groove 504 adapted to the locking block 503 is opened on the side of the T-shaped plate 3 near the locking block 503. A first pull rod 505 is fixedly connected to the side of the first slider 502 away from the T-shaped plate 3. A first spring 506 is sleeved on the first pull rod 505. The side of the first pull rod 505 away from the first slider 502 extends to the outside of the housing 501 and is rotatably connected to a hanging plate 507. A locking block 508 adapted to the hanging plate 507 is fixedly connected to the outside of the housing 501. A first inclined surface is provided at the top of the end of the locking block 503 near the locking groove 504.

[0025] Those skilled in the art will understand that when the T-shaped locking plate 3 is inserted into the T-shaped slot 4, the T-shaped locking plate 3 will press against the first inclined surface at the top of the locking block 503, pushing the first slider 502 to slide within the housing 501 and compressing the first spring 506. When the locking block 503 is aligned with the locking groove 504, the rebound force of the first spring 506 pushes the first slider 502 to reset, causing the locking block 503 to engage with the locking groove 504 to achieve the limiting and locking of the T-shaped locking plate 3. When unlocking, pulling the first lever 505 will move the first slider 502 and the locking block... 503 disengages from the locking groove 504 and engages the hanging plate 507 with the locking block 508 to achieve the unlocked state limit. The locking component 5 utilizes the elasticity of the first spring 506 to automatically lock the T-shaped plate 3 without the need for manual additional fixing, making the operation highly efficient. The precise fit between the locking block 503 and the locking groove 504 ensures the stability of the lock. The cooperation between the hanging plate 507 and the locking block 508 avoids the problem that the locking block 503 will automatically reset after unlocking, causing the T-shaped plate 3 to be unable to be removed smoothly, thus improving the convenience of disassembling and assembling the enclosure plate 2 and the L-shaped plate 1.

[0026] Example 4 Furthermore, the abutment mechanism 6 includes a first threaded rod 601 threadedly connected to the enclosure plate 2. A triangular abutment block 602 is rotatably connected to one end of the first threaded rod 601 near the L-shaped plate 1. A first guide rod 603 is fixedly connected to each of the four corners of the side of the triangular abutment block 602 away from the L-shaped plate 1. The four first guide rods 603 are slidably connected to the enclosure plate 2. A first connecting plate 604 is fixedly connected to one end of the four first guide rods 603 away from the triangular abutment block 602. A rotating rod 605 is rotatably connected to the center of the first connecting plate 604. One end of the rotating rod 605 is fixedly connected to the first threaded rod 601, and a handwheel 606 is fixedly connected to the other end of the rotating rod 605. An anti-loosening component 607 is provided between the first connecting plate 604 and the rotating rod 605.

[0027] Those skilled in the art will understand that rotating the handwheel 606 drives the rotating rod 605 to rotate, which in turn drives the first threaded rod 601, which is threadedly connected to the enclosure plate 2, to move linearly, pushing the triangular abutment block 602 towards the L-shaped plate 1, thereby achieving the abutment against the inserted angle steel. At the same time, the four first guide rods 603 on the triangular abutment block 602 are slidably connected to the enclosure plate 2, providing guidance for the movement of the triangular abutment block 602. The anti-loosening component 607 limits the rotating rod 605 to prevent loosening. This abutment mechanism 6 achieves position adjustment of the triangular abutment block 602 through threaded transmission, and can flexibly adjust the abutment position according to the inserted angle steel of different sizes, with strong adaptability. The guiding effect of the first guide rod 603 ensures the linearity of the movement of the triangular abutment block 602 and avoids skewing during abutment. The setting of the anti-loosening component 607 effectively prevents the threads from loosening due to vibration during construction, ensuring the long-term stability of the abutment fixation.

[0028] Example 5 Furthermore, the triangular abutment block 602 is fixedly connected to the first flexible pad 608 on both sides near the L-shaped plate 1, and the L-shaped plate 1 is fixedly connected to the second flexible pad 609 on both sides near the triangular abutment block 602.

[0029] Those skilled in the art will understand that when the second flexible pads 609 are fixed on both sides of the L-shaped plate 1 near the triangular abutment block 602, and the triangular abutment block 602 moves toward the L-shaped plate 1 to press against the inserted angle steel, the first flexible pad 608 and the second flexible pad 609 directly contact the surface of the angle steel. The flexible material can increase the friction between the angle steel and the angle steel, improve the firmness of the abutment and fixation, and prevent the angle steel from sliding during construction. It can also avoid the hard structure of the triangular abutment block 602 and the L-shaped plate 1 directly squeezing the angle steel, causing surface scratches and deformation, thus playing a good buffering and protective role and ensuring the structural integrity of the inserted angle steel.

[0030] Example 6 Furthermore, the anti-loosening component 607 includes a sliding cavity 6071 opened inside the first connecting plate 604. A second slider 6072 is slidably connected inside the sliding cavity 6071. A limiting block 6073 is fixedly connected to the bottom of the second slider 6072. A plurality of limiting grooves 6074 adapted to the limiting block 6073 and distributed in a ring array are opened on the outer peripheral surface of the rotating rod 605. A second inclined surface is opened at one end of the limiting block 6073 near the limiting groove 6074. A second pull rod 6075 is fixedly connected to the top of the second slider 6072. The top end of the second pull rod 6075 extends to the top of the first connecting plate 604 and is fixedly connected to a pull plate 6076. A second spring 6077 located on the top of the second slider 6072 is sleeved on the second pull rod 6075.

[0031] Those skilled in the art will understand that when the rotating rod 605 rotates to adjust the abutment mechanism 6, the outer peripheral surface of the rotating rod 605 will press against the second inclined surface on the limiting block 6073, pushing the second slider 6072 to slide within the sliding cavity 6071 and compressing the second spring 6077. When the rotating rod 605 stops rotating, the rebound force of the second spring 6077 pushes the second slider 6072 to reset, causing the limiting block 6073 to engage in the limiting grooves 6074 arranged in a ring array on the outer peripheral surface of the rotating rod 605, thereby limiting the rotation rod 605. When unlocking, pulling the pull plate 6076 will drive the second... Pull rod 6075 and second slider 6072 move upward, causing limit block 6073 to disengage from limit groove 6074, allowing rotation rod 605 to rotate. The anti-loosening component 607 utilizes the elasticity of second spring 6077 to automatically limit and prevent loosening of rotation rod 605. Multiple limit grooves 6074 arranged in a ring array can adapt to different rotation angles of rotation rod 605, ensuring that the abutment mechanism 6 can effectively prevent loosening at any adjustment position, completely solving the problem of thread loosening caused by construction vibration. Furthermore, the setting of pull plate 6076 makes the unlocking operation simple and convenient, without affecting the normal adjustment of abutment mechanism 6.

[0032] Example 7 Furthermore, the adjustable support leg 8 includes two support rods 801 fixedly connected to one side of the connecting seat 7. The other ends of the two support rods 801 are fixedly connected to a second connecting plate 802. The two support rods 801 are slidably connected to a sliding plate 803. The side of the sliding plate 803 closest to the second connecting plate 802 is fixedly connected to an internally threaded sleeve 804 located between the two support rods 801. The internally threaded sleeve 804 is slidably connected to the second connecting plate 802. The end of the internally threaded sleeve 804 away from the sliding plate 803 is rotatably connected to a rotating head 805. A mounting plate 806 is hinged to the rotating head 805. The mounting plate 806 has a mounting hole. The side of the connecting seat 7 connected to the support rods 801 is also rotatably connected to a second threaded rod 807. The second threaded rod 807 is threadedly connected to the internally threaded sleeve 804.

[0033] Those skilled in the art will understand that rotating the second threaded rod 807, through its threaded transmission with the internal threaded sleeve rod 804, drives the internal threaded sleeve rod 804 to slide on the second connecting plate 802, thereby causing the sliding plate 803, which is fixed to the internal threaded sleeve rod 804, to move linearly along the two support rods 801, thus achieving flexible adjustment of the overall length of the adjustable support leg 8. After adjustment, the angle of the mounting plate 806 is adjusted by rotating the head 805, and the mounting plate 806 is fixed to the construction ground or support structure through the mounting hole, providing stable support for the device. The adjustable support leg 8 achieves precise length adjustment through threaded transmission, and can flexibly adjust the support height and spacing according to the actual working conditions of the construction site, adapting to different construction environments. The hinged design of the rotating head 805 and the mounting plate 806 allows the support angle of the support leg to be freely adjusted, further improving the on-site adaptability of the device. At the same time, the split telescopic structure can be retracted to its shortest length during transportation, and with the folding and fixing of the clamping and fixing mechanism 10, the transportation volume of the device is greatly reduced.

[0034] Example 8 Furthermore, a through groove 808 is provided on the connecting seat 7, one end of the second threaded rod 807 extends into the through groove 808 and is fixedly connected to the first knob 809, the edge of the first knob 809 is exposed outside the through groove 808, and a travel limit plate 810 is fixedly connected to the support rod 801.

[0035] Those skilled in the art will understand that when adjusting the length of the adjustable support leg 8, the second threaded rod 807 can be driven to rotate simply by turning the first knob 809 exposed outside the through groove 808. No additional operating tools are required, and the adjustment can be completed manually, making the operation simple and convenient.

[0036] Example 9 Furthermore, the clamping and fixing mechanism 10 includes a mounting groove 1001 opened on the outer side of the L-shaped extension frame 9. A double-threaded rod 1002 is rotatably connected in the mounting groove 1001. A second guide rod 1003 symmetrically distributed on the upper and lower sides of the double-threaded rod 1002 is also fixedly connected in the mounting groove 1001. A clamping plate 1004 is threadedly connected to both the positive and negative thread sections of the double-threaded rod 1002. Both clamping plates 1004 are slidably connected to the second guide rod 1003. The clamping surface of the clamping plate 1004 is adapted to the internal threaded sleeve 804 of the adjustable support leg 8.

[0037] Those skilled in the art will understand that during device transportation, the adjustable legs 8 are first retracted to their shortest length and drawn towards the L-shaped extension frame 9. Then, the double-threaded rod 1002 is rotated, and the transmission of its forward and reverse threaded sections drives the two clamping plates 1004 to move closer to each other along the second guide rod 1003, so that the clamping surfaces of the clamping plates 1004 are tightly fitted with the internal threaded sleeve rod 804 of the adjustable legs 8, thereby clamping and fixing the two adjustable legs 8. This clamping and fixing mechanism 10 is achieved through the double-threaded rod 1002. The forward and reverse threaded transmission of 02 enables the synchronous opening and closing of the two clamping plates 1004, which can quickly complete the folding, fixing and unlocking of the adjustable support leg 8, making the operation highly efficient. The second guide rod 1003 provides precise guidance for the movement of the clamping plate 1004, ensuring the centering of the clamping. The precise fit between the clamping plate 1004 and the internal threaded sleeve rod 804 ensures the firmness of the fixation, effectively preventing the adjustable support leg 8 from shaking or falling apart during transportation, greatly reducing the transportation volume of the device and improving the convenience of transportation and storage.

[0038] Example 10 Furthermore, in the two clamping and fixing mechanisms 10, the ends of the double-threaded rods 1002 that are far apart from each other extend to the outside of the L-shaped extension frame 9 and are fixedly connected to a second knob 1005. The ends of the two double-threaded rods 1002 that are close to each other are fixedly connected to an extension rod 1006. The ends of the two extension rods 1006 that are close to each other are fixedly connected to a bevel gear 1007. The two bevel gears 1007 mesh with each other. A reinforcing plate 1008 is also fixedly connected to the outside of the L-shaped extension frame 9. The extension rod 1006 is rotatably connected to the reinforcing plate 1008. A third flexible pad 1009 is fixedly connected to the clamping surface of the clamping plate 1004.

[0039] Those skilled in the art will understand that during operation, rotating any one of the second knobs 1005 will drive the double-ended threaded rods 1002 of the two clamping and fixing mechanisms 10 to rotate synchronously through the transmission of the double-ended threaded rod 1002, the extension rod 1006, and the meshing bevel gear 1007, thereby achieving synchronous clamping and fixing of the two adjustable legs 8. The reinforcing plate 1008 provides rotational support for the extension rod 1006, improving the stability of the transmission structure. The third flexible pad 1009 on the clamping surface of the clamping plate 1004 contacts the internal threaded sleeve 804 of the adjustable leg 8. This design increases clamping friction and improves fixation stability, while also preventing the hard structure of the clamping plate 1004 from scratching the surface of the internal threaded sleeve 804, thus providing a buffering and protective function. The structure achieves synchronous linkage between the two clamping and fixing mechanisms 10 through the bevel gear 1007, eliminating the need for separate operation and significantly improving the efficiency of the outrigger retraction and fixing. The addition of the reinforcing plate 1008 enhances the load-bearing capacity of the transmission structure and prevents structural deformation during transmission. The third flexible pad 1009 balances fixation stability and structural protection, further improving the function of the clamping and fixing mechanism 10.

[0040] The working principle and usage procedure of this device are as follows: Before the installation of the angle steel insertion in the power transmission line, the device is transported to the construction site. During transportation, by rotating the second knob 1005, the double-threaded rod 1002, the extension rod 1006, and the meshing bevel gear 1007 drive the clamping plates 1004 of the two clamping and fixing mechanisms 10 on the L-shaped extension frame 9 to move closer together along the second guide rod 1003. This retracts the adjustable support leg 8 to its shortest length and then closes it, clamping it with the clamping plate 1004 and the third flexible pad 1009 at the internal threaded sleeve rod 804, reducing the size of the device. Upon arrival at the construction site... After landing, rotate the second knob 1005 in the opposite direction to unlock the clamping and fixing mechanism 10, unfold the adjustable support leg 8, rotate the first knob 809 to drive the second threaded rod 807 to rotate, and drive the sliding plate 803 to slide along the support rod 801 through the thread transmission with the internal threaded sleeve rod 804. Adjust the adjustable support leg 8 to a suitable length, use the rotating head 805 to adjust the angle of the mounting plate 806 and fix it to the construction support surface through the mounting hole. The travel limit plate 810 prevents the sliding plate 803 from falling off. Then insert the T-shaped clamping plates 3 at both ends of the enclosure plate 2 into the T-shaped clamping slots 4 of the L-shaped plate 1. 3. The first inclined surface of the locking block 503 is pressed, and the first spring 506 is compressed by the first slider 502. When the locking block 503 is aligned with the locking groove 504, the first spring 506 resets and pushes the locking block 503 into the locking groove 504 to complete the locking. The hanging plate 507 and the locking block 508 cooperate to achieve the unlocking limit. The inserted angle steel is placed into the fixed cavity formed by the L-shaped plate 1 and the enclosure plate 2. The plumb line is suspended on the plumb line hook 11 of the L-shaped extension frame 9 to calibrate the perpendicularity and horizontality of the device and the angle steel. After calibration, the handwheel 606 is turned to drive the rotating rod 605 to rotate, driving the first threaded rod 601. The triangular abutment block 602 is pushed to move towards the L-shaped plate 1. The first guide rod 603 guides the triangular abutment block 602. The first flexible pad 608 and the second flexible pad 609 contact the surface of the angle steel to achieve buffering and clamping. At the same time, in the anti-loosening component 607, the rotating rod 605 squeezes the second inclined surface of the limiting block 6073, and the second spring 6077 is compressed by the second slider 6072. After the rotating rod 605 stops, the second spring 6077 resets and pushes the limiting block 6073 into the limiting groove 6074 to achieve anti-loosening and limiting of the rotating rod 605. After the angle steel is fixed, the concrete foundation pouring construction can be carried out.
