Description

Technical Field

[0001] The invention belongs to the technical field of station platforms, and in particular relates to a steel pipe tower station platform with adjustable installation dimensions. Background Art

[0002] With the development of the global energy internet, the construction of national cross-regional UHV transmission network projects is urgently needed. In the construction of UHV transmission lines, the steel pipe tower structure has the characteristics of high rigidity, good cross-sectional force characteristics, and small footprint, and has been well applied in UHV transmission lines. When the steel pipe tower is connected in the project, a detachable standing platform will be set on the steel pipe tower for workers to work, and it will be dismantled after the work is completed.

[0003] At present, the standing platform of the steel pipe tower is generally of specific installation size, and is generally only suitable for steel pipe towers of specific diameter and specific taper. Its versatility is poor. For example, the diameter of the main material of the steel pipe tower generally increases gradually from top to bottom (in a tapered shape). For steel pipe towers of different heights or for steel pipe towers of different sizes, because of their different installation diameters or installation tapers, standing platforms of different installation sizes are required, which causes a certain amount of material waste and increases the difficulty of management and carrying. Summary of the invention

[0004] In view of the shortcomings and defects in the prior art, the purpose of the present invention is to provide a steel pipe tower standing platform with adjustable installation dimensions, which solves the problem that the steel pipe tower standing platform in the prior art is generally only suitable for steel pipe towers of specific diameters and specific tapers, and has poor versatility. Different height positions of the steel pipe tower or for steel pipe towers of different sizes require standing platforms with different installation dimensions because of their different installation diameters or installation tapers, which causes a certain amount of material waste and increases the difficulty of management and carrying.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a steel pipe tower station platform with adjustable installation size, comprising two detachably connected semi-circular ring platform plates that can form a circular ring, the semi-circular ring platform plates are provided with semi-circular ring grooves, and a semi-circular ring station plate that can be slid up and down along the semi-circular ring groove is embedded in the semi-circular ring groove, and a deformable tightening belt that is surrounded by the steel pipe tower and can be tightened from one end is provided in the semi-circular hole of the semi-circular ring platform plate, and a plurality of pressing plates are slidably sleeved on the tightening belt. The semicircular platform plate and the semicircular station plate are connected to the pressing plate through an adjusting mechanism that can make the pressing plate tightly attached to the surface of the steel pipe tower with different tapers or diameters. An outer air-filled cortex into which air can be inflated is arranged between the bottom surface of the semicircular groove and the bottom surface of the semicircular station plate. An inner air-filled cortex communicated with the outer air-filled cortex is arranged between the inner wall surface of the semicircular platform plate and the pressing plate. When a person stands on the semicircular station plate and makes it slide downward under force, the outer air-filled cortex and the semicircular station plate can cause the adjusting mechanism to be squeezed toward the pressing plate.

[0006] As a further improvement of the present invention, the adjustment mechanism includes two first screws hingedly connected to the pressure plate, and two second screws that can extend into the semicircular ring grooves in the semicircular ring platform plate. A circular hole with a diameter greater than the diameter of the second screw is opened on the semicircular ring platform plate at the position where the second screw passes through. The first screw and the second screw are connected by a threaded sleeve that is threadedly matched with them respectively, and a tightening nut is provided on the second screw on one side of the inner wall surface of the semicircular ring platform plate.

[0007] As a further improvement of the present invention, one end of the second screw at the lower side extending into the semicircular groove is mounted on the outer air-filled cortex.

[0008] As a further improvement of the present invention, the semicircular ring station plate is provided with a first inclined surface inclined from top to bottom toward the side away from the steel pipe tower at a position close to the second screw, and the end of the second screw on the upper side extending into the semicircular ring groove is provided with a second inclined surface matching the first inclined surface.

[0009] As a further improvement of the present invention, the semicircular ring platform plate is provided with a plurality of embedded sliding grooves on the outside of the semicircular ring groove, the semicircular ring station plate is provided with a slider that slides with the embedded sliding groove, and a spring is provided between the bottom of the embedded sliding groove and the bottom surface of the slider.

[0010] As a further improvement of the present invention, a round rod is vertically provided at the bottom of the embedded slide groove, which is slidably matched with the slider and can extend to a certain height from the top of the slider, and the spring is sleeved outside the round rod.

[0011] As a further improvement of the present invention, all the round rods on each semicircular ring platform plate are connected by guardrails.

[0012] As a further improvement of the present invention, an inflation nozzle capable of extending into the outer inflation cortex is provided on the outer side of the semicircular ring platform plate.

[0013] As a further improvement of the present invention, the fastening belt is a long belt that can be wrapped into a circle matching the steel pipe tower, and the two ends of the long belt are locked by buckles.

[0014] As a further improvement of the present invention, the pressing plate is detachably installed on the fastening belt.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The steel pipe tower station platform is set as a structure of two semicircular ring platform plates, a semicircular ring groove is provided on the semicircular ring platform plate, and a semicircular ring station plate that can slide up and down is embedded in the semicircular ring groove, a fastening belt is provided in the circular hole of the semicircular ring station plate, and a plurality of pressing plates are sleeved on the fastening belt, and the semicircular ring platform plate and the semicircular ring station plate are connected with the pressing plate through an adjusting mechanism, and an outer pneumatic cortex is provided between the bottom surface of the semicircular ring groove and the bottom surface of the semicircular ring station plate, and an inner pneumatic cortex is provided between the inner wall surface of the semicircular ring platform plate and the pressing plate; when installing and fastening the steel pipe tower station platform, the two semicircular rings are fastened to the steel pipe tower station platform. The platform plate is sleeved on the outside of the steel tube tower and fastened to each other. Then the fastening belt of the sleeve pressure plate is set around the target height position of the steel tube tower, and then the fastening belt is expanded. Due to the deformability of the fastening belt, the fastening belt is firmly clamped on the steel tube tower, and the pressure plate on it is close to the steel tube tower. Then, the adjustment mechanism is adjusted, and the outer inflatable cortex and the inner inflatable cortex are inflated. The adjustment mechanism and the inner inflatable cortex are expanded between the pressure plate and the semi-circular platform plate, pushing the pressure plate to press toward the steel tube tower, so that the two semi-circular platform plates are tightened and expanded on the steel tube tower. The purpose of fixing two semicircular ring platform plates on steel pipe towers with different diameters and different tapers is achieved, and the versatility is strong, avoiding the waste of materials caused by making steel pipe tower platforms of different specifications and increasing the difficulty of management and carrying. In addition, when people stand on the semicircular ring standing board and make it slide downward under force, the outer inflatable cortex and the semicircular ring standing board can make the adjusting mechanism squeeze in the direction of the pressure plate; thus, when the workers stand on the semicircular ring standing board during operation, the outer inflatable cortex and the adjusting mechanism further push the pressing plate in the direction of the steel pipe tower, and the fastening degree is stronger. The firmness of the semicircular ring platform plate on the steel pipe tower is improved to avoid the unstable fixation caused by the force of the people standing on the semicircular ring platform plate, and it has a certain self-locking property. In addition, the inner inflatable cortex is expanded and tightened between the semicircular ring platform plate and the inclined pressure plate. When the people standing on the semicircular ring station plate are forced to move downward, the outer inflatable cortex is compressed, so that the gas inside it moves and squeezes toward the inner inflatable cortex, thereby making the inner inflatable cortex more expanded and tightened, so that the firmness of the semicircular ring platform plate and the steel pipe tower is enhanced. In addition, the inner inflatable cortex forms a fastened wedge structure with high firmness.

[0017] 2. By setting the adjustment mechanism as a structure of a first screw, a second screw, a threaded sleeve and a tightening nut, and the first screw is hingedly connected to the pressure plate, the length of the first screw and the second screw is adjusted by rotating the threaded sleeve, so that the first screw extends into the semicircular ring groove, and then the first screw and the second screw are expanded and fixed between the pressure plate and the semicircular ring platform plate by rotating the tightening nut, so that the adjustment is simple and convenient.

[0018] 2. By extending one end of the second screw on the lower side into the semicircular ring groove and placing it on the outer inflatable cortex, when a person standing on the semicircular ring standing plate is forced to move downward, the outer inflatable cortex is compressed, and the gas inside expands to both sides, thereby pushing the second screw on one side to move toward the steel pipe tower, and then pushing the pressure plate to press the steel pipe tower more tightly. The more people stand on the platform, the greater the pressing force on the pressure plate, thereby improving the fixing firmness of the platform and avoiding its firmness being affected by standing people.

[0019] 4. By arranging the first inclined surface and the second inclined surface that cooperate with each other on the semicircular standing plate and the second screw rod at the top, when a person standing on the semicircular standing plate is forced to move downward, the semicircular standing plate pushes the second screw rod to move toward the steel pipe tower through the first inclined surface and the second inclined surface, thereby pushing the pressure plate to press the steel pipe tower more tightly, and the more people stand, the greater the pressing force on the pressure plate, thereby improving the fixing firmness of the platform and avoiding its firmness being affected by standing people.

[0020] 5. By providing an embedded slide groove on the semicircular ring platform plate, a slider that slides with the embedded slide groove is provided on the semicircular ring station plate, and a spring is provided between the bottom of the embedded slide groove and the bottom surface of the slider, the sliding connection between the semicircular ring station plate and the semicircular ring platform plate is improved to avoid the semicircular ring station plate from shaking in the horizontal direction.

[0021] 6. A round rod is vertically provided at the bottom of the embedded slide groove, which is slidably matched with the slider and can extend to a certain height from the top of the slider. The spring sleeve is arranged outside the round rod, and all the round rods on each semi-circular ring platform plate are connected by a guardrail. The round rod can guide the sliding of the semi-circular ring platform on the one hand, and support the connecting guardrail on the other hand to protect the safety of the staff.

[0022] 7. By making the fastening belt into a long belt that can be wrapped into a circle matching the steel pipe tower, and locking the two ends of the long belt by buckles, it can be suitable for clamping steel pipe towers of different diameters and tapers, and the pressure plate thereon can be attached to steel pipe towers of different diameters and tapers, so as to facilitate the adjustment mechanism to expand the pressure plate and the semi-circular ring platform plate. It has strong versatility, simple structure and installation, and strong connection firmness. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-6 The present invention is further described in detail. For a clearer illustration, only the structures related to the inventive point of the present invention are shown in the figure.

[0032] For the convenience of description, the coordinate system is defined as Figure 1 As shown, the left-right direction is the horizontal direction, the front-back direction is the longitudinal direction, and the up-down direction is the vertical direction.

[0033] The embodiment of the present invention discloses a steel pipe tower station platform with adjustable installation dimensions. Figure 1 A steel pipe tower station platform with adjustable installation size includes two detachably connected semi-circular platform plates 1 that can form a ring shape. Specifically, the two semi-circular platform plates 1 are connected by a connecting plate 17 and bolts. The semi-circular platform plate 1 is provided with a semi-circular groove 2, and a semi-circular station plate 3 that can be slid up and down along the semi-circular groove 2 is embedded therein. In addition, Figure 5 and Figure 6 As shown, the semicircular platform plate 1 is provided with a plurality of embedded slide grooves 11 on the outer side of the semicircular groove 2, and the semicircular stand plate 3 is provided with a slider 10 that slides with the embedded slide groove 11, and a spring 12 is provided between the bottom of the embedded slide groove 11 and the bottom surface of the slider 10 to improve the sliding connection between the semicircular stand plate 3 and the semicircular platform plate 1 and prevent the semicircular stand plate 3 from shaking in the horizontal direction. In addition, a round rod 13 that slides with the slider 10 and can extend to a certain height from the top of the slider 10 is vertically provided at the bottom of the embedded slide groove 11, and the spring 12 is sleeved on the outside of the round rod 13; as shown in FIG. Figure 1 and Figure 3As shown, all the round rods 13 on each semicircular ring platform plate 1 are connected by guardrails 14. The round rods 13 can guide the sliding of the semicircular ring platform plate 3 on the one hand, and can support and connect the guardrails 14 on the other hand to protect the safety of the staff.

[0034] like Figure 2 and Figure 4 As shown, a deformable fastening belt 4 is arranged in the semi-circular hole of the semi-circular platform plate 1, which is surrounded by the steel pipe tower 9 and can be fastened from one end. A plurality of detachable pressing plates 5 are slidably sleeved on the fastening belt 4. The fastening belt 4 is a long belt that can be surrounded by a circle matching the steel pipe tower 9. Its shape structure and clamping principle are similar to those of a belt used on clothes. The long belt can be surrounded by a ring, and its two ends are locked by a buckle 16 (the buckle 16 is a buckle 16 structure of a clothes belt), so that it can be used to clamp steel pipe towers 9 of different diameters and tapers, and can The pressure plate 5 thereon is attached to the steel pipe tower 9 with different diameters and tapers, so as to facilitate the adjustment mechanism 6 to expand and tighten the pressure plate 5 and the semi-circular ring platform plate 1. It has strong versatility, simple structure and installation, and strong connection strength. The pressure plate 5 can slide on the fastening belt 4, which is convenient for adjusting the position of the sliding pressure plate 5 according to the diameter of the steel pipe tower 9. The pressure plate 5 can be removed from the fastening belt 4, which is convenient for dividing the two semi-circular ring platform plates 1 into two independent entities during disassembly, avoiding all the pressure plates 5 from being connected together through the fastening belt 4, so that the two semi-circular ring platform plates 1 are inseparable.

[0035] like Figure 2 and Figure 4 As shown, the semicircular platform plate 1 and the semicircular station plate 3 are connected to the pressing plate 5 through an adjustment mechanism 6 that can make the pressing plate 5 fasten to the surface of the steel pipe tower 9 with different tapers or diameters. An outer air-filled cortex 7 that can be inflated is provided between the bottom surface of the semicircular groove 2 and the bottom surface of the semicircular station plate 3. An inner air-filled cortex 8 that communicates with the outer air-filled cortex 7 is provided between the inner wall surface of the semicircular platform plate 1 and the pressing plate 5. The inner air-filled cortex 8 and the outer air-filled layer can be connected by opening a through hole on the semicircular platform plate 1 to connect the two. Figure 6 As shown, the outer side of the semicircular platform plate 1 is provided with an inflating nozzle 15 which can extend into the outer inflatable cortex 7. When inflating, the inner inflatable cortex 8 and the outer inflatable layer are inflated through the inflating nozzle 15. When a person stands on the semicircular standing plate 3 and makes it slide downward under force, the outer inflatable cortex 7 and the semicircular standing plate 3 can make the adjusting mechanism 6 squeeze toward the pressing plate 5, so that the pressing plate 5 can clamp the steel pipe tower 9 more tightly.

[0036] like Figure 4As shown, the adjustment mechanism 6 includes two first screws 61 hingedly connected to the pressure plate 5, and two second screws 62 that can extend into the semicircular ring groove 2 in the semicircular ring platform plate 1. A circular hole with a diameter larger than the diameter of the second screw 62 is provided on the semicircular ring platform plate 1 at the position where the second screw 62 passes through. The first screw 61 and the second screw 62 are connected by a threaded sleeve 63 that is threadedly matched with them respectively. A tightening nut 64 is provided on the second screw 62 on one side of the inner wall of the semicircular ring platform plate 1. When adjusting, the length of the first screw 61 and the second screw 62 is adjusted by rotating the threaded sleeve 63 so that the first screw 61 extends into the semicircular ring groove 2, and then the first screw 61 and the second screw 62 are tightened and fixed between the pressure plate 5 and the semicircular ring platform plate 1 by rotating the tightening nut 64. The adjustment is simple and convenient.

[0037] In addition, one end of the second screw 62 on the lower side extends into the semicircular ring groove 2 and is mounted on the outer inflatable cortex 7. Therefore, when a person standing on the semicircular ring standing plate 3 is forced to move downward, the outer inflatable cortex 7 is compressed, and the gas inside expands to both sides, thereby pushing the second screw 62 on one side to move toward the steel pipe tower 9, and then pushing the pressing plate 5 to press the steel pipe tower 9 more tightly. The more people stand, the greater the pressing force on the pressing plate 5, thereby improving the fixing firmness of the platform and preventing its firmness from being affected by standing people.

[0038] The semicircular stand plate 3 is provided with a first inclined surface 65 inclined from top to bottom toward the side away from the steel pipe tower 9 at a position close to the second screw 62, and the second screw 62 on the upper side is provided with a second inclined surface 66 matching the first inclined surface 65 at one end extending into the semicircular groove 2. Therefore, when a person standing on the semicircular stand plate 3 is forced to move downward, the semicircular stand plate 3 pushes the second screw 62 to move toward the steel pipe tower 9 through the first inclined surface 65 and the second inclined surface 66, thereby pushing the pressing plate 5 to press the steel pipe tower 9 more tightly, and the more people standing, the greater the pressing force on the pressing plate 5, thereby improving the fixing firmness of the platform and preventing its firmness from being affected by standing people.

[0039] The implementation and installation process of the present invention is as follows: two semi-circular platform plates 1 are wrapped around the target height position of the steel pipe tower 9 to be installed, and then the semi-circular platform plates 1 are fastened and fixed by connecting plates 17 and bolts, and the fastening belts 4 are passed through all the pressure plates 5, and then the fastening belts 4 are surrounded into a ring through the lock buckle 16, and the fastening belts 4 are fastened so that the fastening belts 4 are clamped and fixed on the steel pipe tower 9. At this time, the pressure plate 5 is attached to the steel pipe tower 9 due to the clamping effect of the fastening belts 4, and then the rotating threaded sleeve 63 and the second thread are adjusted. Rod 62, so that the two second screw rods 62 are both inserted into the semicircular ring groove 2, and the second inclined surface 66 of the upper second screw rod 62 contacts and cooperates with the first inclined surface 65 of the semicircular ring platform plate 3, and then the tightening nut 64 is adjusted so that the tightening nut 64 is pressed against the inner wall of the annular hole of the semicircular ring platform plate 1, so that the first screw rod 61, the second screw rod 62 and the threaded sleeve 63 tighten and fix the steel pipe tower 9 and the semicircular ring platform plate 1 to each other through the tightening nut 64 and the pressure plate 5, that is, the preliminary fixation of the semicircular ring platform plate 1 on the steel pipe tower 9 is completed. Then, the inner inflatable cortex 8 and the outer inflatable cortex 7 are inflated through the inflation nozzle 15, so that the inner inflatable cortex 8 and the outer inflatable cortex 7 are filled with gas and expanded. The expansion of the steel pipe tower 9 and the semi-circular ring platform plate 1 by the inner inflatable cortex 8 further fastens the semi-circular ring platform plate 1 on the steel pipe tower 9, and then the rotating tightening nut 64 is further adjusted to make the semi-circular ring platform plate 1 and the pressure plate 5 expand and tighten firmly, thereby completing the installation of the semi-circular ring platform plate 1, i.e., the platform of the steel pipe tower 9. When a worker stands on the semicircular stand plate 3, the outer inflatable cortex 7 is compressed, and the semicircular stand plate 3 moves slightly downward. On the one hand, the downward movement of the semicircular stand plate 3 pushes the second screw 62 matched with it to the steel pipe tower 9 through the first inclined surface 65, so that the device further clamps the steel pipe tower 9; on the other hand, the outer inflatable cortex 7 is compressed, so that the gas inside it expands outward, pushing the second screw 62 in contact with it to the steel pipe tower 9, so that the device further clamps the steel pipe tower 9; thirdly, the outer inflatable cortex 7 is compressed, pushing the gas inside it to flow to the inner inflatable cortex 8, increasing the expansion force of the inflatable cortex, thereby increasing the expansion of the semicircular platform plate 1 on the steel pipe tower 9. In summary, the device ensures the installation firmness of the platform when people stand on the steel pipe tower 9 from three aspects.

[0040] The main technical effects of the present invention are as follows: the station platform of the steel pipe tower 9 is set as a structure of two semicircular ring platform plates 1, a semicircular ring groove 2 is provided on the semicircular ring platform plate 1, and a semicircular ring station plate 3 that can slide up and down is embedded in the semicircular ring groove 2, a fastening belt 4 is provided in the circular hole of the semicircular ring station plate 3, a plurality of pressing plates 5 are sleeved on the fastening belt 4, and the semicircular ring platform plate 1 and the semicircular ring station plate 3 are connected to the pressing plate 5 through an adjusting mechanism 6, and an outer pneumatic cortex 7 is provided between the bottom surface of the semicircular ring groove 2 and the bottom surface of the semicircular ring station plate 3, and an inner pneumatic cortex 8 is provided between the inner wall surface of the semicircular ring platform plate 1 and the pressing plate 5; When installing the station platform for fastening the steel pipe tower 9, two semicircular platform plates 1 are sleeved on the outside of the steel pipe tower 9 and fastened to each other, and then the fastening belt 4 with the pressure plate 5 is set around the target height position of the steel pipe tower 9, and then the fastening belt 4 is expanded. Due to the deformability of the fastening belt 4, the fastening belt 4 is firmly clamped on the steel pipe tower 9, and the pressure plate 5 thereon is close to the steel pipe tower 9. Then, the adjustment mechanism 6 is adjusted, and the outer inflatable cortex 7 and the inner inflatable cortex 8 are inflated. The adjustment mechanism 6 and the inner inflatable cortex 8 are expanded between the pressure plate 5 and the semicircular platform plate 1, pushing the pressure plate 5 The semicircular ring platform plates 1 are pressed in the direction of the steel pipe tower 9, so that the two semicircular ring platform plates 1 are tightened and expanded on the steel pipe tower 9, thereby achieving the purpose of fixing the two semicircular ring platform plates 1 on the steel pipe towers 9 with different diameters and different tapers, and the versatility is strong; in addition, when people stand on the semicircular ring stand plate 3 and make it slide downward under force, the outer inflatable cortex 7 and the semicircular ring stand plate 3 can make the adjustment mechanism 6 squeeze in the direction of the pressure plate 5; thus, when the workers stand on the semicircular ring stand plate 3, the outer inflatable cortex 7 and the adjustment mechanism 6 further push and squeeze the pressure plate 5 in the direction of the steel pipe tower 9, and the tightening degree is stronger, which improves The firmness of the semicircular ring platform plate 1 on the steel pipe tower 9 avoids the unstable fixation caused by the force of people standing on the semicircular ring platform plate 1, and has a certain self-locking property. In addition, the inner inflatable cortex 8 is expanded and tightened between the semicircular ring platform plate 1 and the inclined pressure plate 5. When the person standing on the semicircular ring standing plate 3 is forced to move downward, the outer inflatable cortex 7 is compressed, so that the gas inside it moves and squeezes toward the inner inflatable cortex 8, thereby making the inner inflatable cortex 8 more expanded and tightened, so that the firmness of the semicircular ring platform plate 1 and the steel pipe tower 9 is enhanced. In addition, the inner inflatable cortex 8 forms a fastened wedge structure with high firmness.
