Description

Technical Field

[0001] The utility model relates to the field of steel structure installation, in particular to an adjustable steel structure installation support device. Background Art

[0002] Steel structure is an engineering structure composed of steel plates, round steel, steel pipes, steel cables and various steel sections, which are processed, connected and installed. Steel structure needs to withstand various possible natural and man-made environmental effects. It is an engineering structure and building with sufficient reliability and good social and economic benefits. It is widely used in high-rise buildings, large factories, large-span space structures, light steel structures and residential buildings. In the daily installation process of steel structure, support equipment is needed to assist the steel structure in installation operations.

[0003] For example, the utility model with application number 202321707366.3 discloses an adjustable steel structure installation support device, including a support upright installed above the support of the installation tripod, the support upright is provided with a lifting support rod at the support rod end, and the frame end of the main support platform is symmetrically connected to multiple groups of auxiliary support platforms, and the multiple groups of auxiliary support platforms are connected to the lifting sleeve through support arms symmetrically arranged in pairs. The utility model uses an expandable and adjustable plate surface pressure-bearing mechanism to support the pressure point. When the load is too heavy, the main support platform and the auxiliary support platform are expanded and opened at the same time to increase the support area, so that it has a more stable support effect, and at the same time avoid the situation where the support surface is small and the support point is punctured. When the load area of ​​the load is small, the auxiliary support platform is folded and retracted, and the plate support of the main support platform and the side auxiliary support of the auxiliary support platform are used to improve the support stability.

[0004] Although this adjustable steel structure installation support equipment can provide auxiliary support for the installation of steel structures when in use, the adjustable range of the support area of ​​the support platform is limited, and in particular, the support length cannot be effectively increased. When supporting and installing a long steel structure, the support area is still insufficient when both the main support platform and the auxiliary support platform are used at the same time. The long steel structure may easily tilt due to insufficient support area, thereby requiring the operator to manually assist in the installation of the steel structure, which increases the complexity of the steel structure installation and reduces the efficiency of the steel structure installation.

[0015] Preferably, the second adjustment mechanism comprises two inclined slots, two second connecting rods matched with the inclined slots and two through slots located on the same straight line, the two inclined slots gradually move away from each other along the length direction, the through slots are arranged on the top surface of the third support plate, and the two second connecting rods respectively pass through the two through slots and are fixedly connected to the two first support plates;

[0016] The inclined slot can move horizontally to drive the two second connecting rods to move closer to each other or away from each other.

[0017] Preferably, the second adjusting mechanism is arranged in the third supporting plate, and the second adjusting mechanism further comprises a sliding plate and a driving mechanism, the driving mechanism is connected to the sliding plate to drive the sliding plate to move horizontally, and the inclined groove is arranged on the sliding plate.

When this method is adopted, the electric push rod needs to be set on the extension line of the telescopic rod, and the electric push rod can be set inside the first support plate. However, when the electric push rod is configured to directly push the telescopic rod, the electric push rod will be subjected to the reaction force of the steel structure on the adjustable steel structure mounting support device. This radial force greatly affects the service life of the electric push rod. In addition, considering that the electric push rod needs to dissipate heat during operation, heat dissipation holes need to be set on the first support plate. The provision of heat dissipation holes may affect the strength of the first support plate.

[0043] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0044] In the present utility model, unless otherwise stated, directional words contained in terms such as "symmetrical, between, inside, facing, horizontal, away from, top surface" merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0045] See also Figure 1-2 The adjustable steel structure installation support device comprises a support rod 1 and two support structures symmetrically arranged on the top of the support rod 1, the support structure comprises a first adjustment mechanism, a first support plate 2 and a second support plate 3, and the first support plate 2 and the second support plate 3 are connected by a telescopic first adjustment mechanism;

[0046] The first adjustment mechanism is arranged in the first support plate 2 . A first telescopic slot 21 is arranged on the surface of the first support plate 2 facing the second support plate 3 . The first adjustment mechanism includes a telescopic rod 41 . The telescopic rod 41 extends from the first telescopic slot 21 and is connected to the second support plate 3 .

[0047] Through the implementation of the above technical solution, the support structure is used to support the steel structure. When encountering a long steel structure, the telescopic rod 41 can be extended through the first adjustment mechanism to push the second support plate 3 to a farther position, thereby increasing the support length of the support structure and meeting the effective support requirements for the long steel structure.

[0048] In order to ensure the stability of the adjustable steel structure installation support device during operation, two support structures are symmetrically arranged. While achieving stability, the two support structures can simultaneously extend the telescopic rod 41 far away, so that the effective support length of the adjustable steel structure installation support device is doubled, and the support of the long steel structure is more effectively achieved.

[0049] During use, the upper surfaces of the first support plate 2 and the second support plate 3 support the steel structure, and the first adjustment mechanism is arranged inside the first support plate 2, so that the overall adjustable steel structure installation support device is more convenient for storage and transfer, avoiding interference with the steel structure during use.

[0050] In one embodiment, the first adjustment mechanism is configured such that the electric push rod directly pushes the telescopic rod 41. When this method is adopted, the electric push rod needs to be set on the extension line of the telescopic rod 41, and the electric push rod can be set inside the first support plate 2. However, when the electric push rod is configured to directly push the telescopic rod 41, the electric push rod will be subjected to the reaction force of the steel structure on the adjustable steel structure mounting support device. This radial force greatly affects the service life of the electric push rod. In addition, considering that the electric push rod needs to dissipate heat during operation, the first support plate 2 needs to be provided with heat dissipation holes, and the provision of heat dissipation holes may affect the strength of the first support plate 2.

[0051] In this embodiment, preferably, the first adjustment mechanism further includes a push rod 42 that can be extended and retracted, a rack 43 fixedly connected to the push rod 42, a gear 44 matched with the rack 43, a swing rod 45 and a first slider 46, the gear 44 is fixedly connected to the first support plate 2, one end of the swing rod 45 is fixedly connected to the gear 44, and the other end is slidably connected to the first slider 46 to drive the first slider 46 to move horizontally, and the telescopic rod 41 is connected to the first slider 46 to achieve extension and retraction;

[0052] A first sliding groove 22 is provided in the first supporting plate 2 , and the first sliding block 46 cooperates with the first sliding groove 22 .

[0053] In order to avoid the problem that the electric push rod is easily subjected to radial force when the electric push rod directly pushes the telescopic rod 41 , the utility model provides a mechanical structure for changing the thrust direction between the electric push rod and the telescopic rod 41 .

[0054] like Figure 3 As shown, the electric push rod 7 pushes the rack 43 so that the rack 43 can reciprocate in the horizontal direction, and then the gear 44 matched with the rack 43 will rotate. Since the gear 44 is fixedly connected to the first support plate 2, the gear 44 can only rotate in place and will not move with the rack 43. When the gear 44 rotates, it will drive the swing rod 45 to swing. When the swing rod 45 swings, it drives the first slider 46 to move linearly along the first slide groove 22. The linear movement of the first slider 46 drives the telescopic rod 41 to extend or retract, thereby avoiding the situation where the electric push rod 7 directly pushes the telescopic rod 41, effectively avoiding the problem of the electric push rod 7 being subjected to radial force. At the same time, the electric push rod 7 is arranged outside the first support plate 2, which is more convenient for heat dissipation and maintenance.

[0055] Preferably, if Figure 3As shown, when the adjustable steel structure installation support device is in the storage state, the gear 44 is located at the farthest end of the rack 43. As the electric push rod 7 pushes the rack 43 to move forward, the gear 44 rotates to drive the swing rod 45 to swing toward the second support plate 3. When the swing rod 45 swings toward the second support plate 3, it drives the first slider 46 to slide toward the second support plate 3, thereby achieving the purpose of extending the telescopic rod 41. When the gear 44 is located at the nearest end of the rack 43, the telescopic rod 41 is extended to the maximum length.

[0056] Therefore, by controlling the electric push rod 7, the stroke of the telescopic rod 41 can be controlled, thereby achieving adjustment of the effective supporting length of the supporting structure.

[0057] In this embodiment, preferably, a guide structure cooperating with the rack 43 is provided in the first support plate 2 .

[0058] The guide structure can not only limit the movement direction of the rack 43, so that the rack 43 and the gear 44 can mesh more reliably, but more importantly, the guide structure can also improve the strength of the rack 43, avoiding the rack 43 from shaking or breaking during use. At the same time, because the guide structure is provided, the working process of the rack 43 is more stable, and radial force on the electric push rod 7 can also be avoided.

[0059] In one embodiment, the guide structure includes a guide hole and a guide rod that cooperate with each other. A guide hole is provided on the side of the rack 43 that faces away from the gear 44, and a guide rod is provided in the first support plate 2. The guide hole passes through the guide rod and can slide freely along the guide rod, thereby achieving a guiding effect on the rack 43. The position where the guide hole contacts the guide rod can provide support for the rack 43 and can also effectively avoid generating radial force on the electric push rod 7.

[0060] In another embodiment, the guide structure includes a guide block 231 and a guide groove 232 that cooperate with each other. A guide block 231 is provided on the side of the rack 43 that faces away from the gear 44, and a guide groove 232 is provided in the first support plate 2. The guide block 231 can slide in the guide groove 232 to guide the rack 43. The position where the guide block 231 contacts the guide groove 232 can provide support for the rack 43, and can also effectively avoid radial force on the electric push rod 7 during use.

[0061] In this embodiment, preferably, the first adjustment mechanism further includes a limiting mechanism, and the limiting mechanism cooperates with the first slider 46 to limit the stroke of the first slider 46 .

[0062] By providing a limiting mechanism to limit the travel of the first sliding block 46 , the overall structural strength of the adjustable steel structure installation support device can be improved.

[0063] In one embodiment, the limiting mechanism includes a limiting block disposed at the end of the first slide groove 22 . One or two limiting blocks can be provided according to actual needs to limit the travel of the first slider 46 by limiting the sliding range of the first slider 46 in the first slide groove 22 .

[0064] Preferably, the limiting mechanism can also be set as a limiting hole 451. The upper end of the first slider 46 is provided with a first connecting rod 461, and the end of the swing rod 45 is provided with a limiting hole 451. The first connecting rod 461 passes through the limiting hole 451 and is fixedly connected to the telescopic rod 41.

[0065] During the swinging process of the swinging rod 45, the first connecting rod 461 will slide in the limiting hole 451. When the adjustable steel structure mounting support device is in the storage state, the first connecting rod 461 is located at the farthest end of the limiting hole 451. As the swinging rod 45 swings, the first connecting rod 461 begins to gradually approach the gear 44 along the limiting hole 451. When the telescopic rod 41 extends half of its stroke, the swinging rod 45 is in a state perpendicular to the rack 43. At this time, the first connecting rod 461 is located at the nearest end of the limiting hole 451. Then the swinging rod 45 continues to swing, and the first connecting rod 461 moves away again until the telescopic rod 41 extends its full stroke, and the first connecting rod 461 is once again located at the farthest end of the limiting hole 451.

[0066] The swing rod 45 is located between the first slider 46 and the telescopic rod 41 , so that the swing rod 45 no longer has the freedom to move up and down, thereby achieving a limiting effect on the swing rod 45 and making the cooperation between the swing rod 45 and the first connecting rod 461 more reliable.

[0067] When the second support plate 3 supports the steel structure, the telescopic rod 41 will have a tendency to move upward, and the fixed connection between the telescopic rod 41 and the first connecting rod 461 realizes the position restriction of the telescopic rod 41. At the same time, the top cover of the first support plate 2 can also limit the height of the telescopic rod 41, thereby ensuring the reliability of the telescopic rod 41.

[0068] Preferably, the first connecting rod 461 is configured to be cylindrical so that its side surface can slide more conveniently in the limiting hole 451 .

[0069] More preferably, a bearing is disposed on the outer sleeve of the first connecting rod 461 so that rolling friction is achieved between the first connecting rod 461 and the limiting hole 451, so that the movement is smoother.

[0070] In this embodiment, preferably, a second telescopic slot 24 is further provided on the surface of the first support plate 2 facing the second support plate 3 , and a sliding rod 31 is provided on the second support plate 3 , and the sliding rod 31 extends into the first support plate 2 through the second telescopic slot 24 .

[0071] When the second support plate 3 supports the steel structure, it will be subjected to the reaction force of the steel structure, and the reaction force on the second support plate 3 will be transmitted to the support rod 1 through the telescopic rod 41. In order to improve the stress of the telescopic rod 41 during use, multiple sliding rods 31 can be provided to perform synchronous telescopic movement with the telescopic rod 41, and the multiple sliding rods 31 can also support the second support plate 3 at the same time, which can not only improve the stress of the telescopic rod 41, but also make the support of the second support plate 3 more reliable.

[0072] In this embodiment, preferably, the adjustable steel structure installation support device also includes a third support plate 5 and a retractable second adjustment mechanism, the third support plate 5 is located at the top of the support rod 1, and the third support plate 5 is connected to the first support plate 2 through the second adjustment mechanism.

[0073] like Figure 1 As shown, when the second adjusting mechanism is extended, the first supporting plate 2 can be pushed out, thereby further increasing the effective supporting length of the adjustable steel structure installation supporting device.

[0074] In one embodiment, the second adjustment mechanism is configured such that the electric push rod directly pushes the first support plate 2. When this method is adopted, the electric push rod needs to be set on the extension line of the first support plate 2, and the electric push rod can be set on the upper surface of the third support plate 5. At this time, a spacing needs to be set between the two first support plates 2 for installing the electric push rod. As with the first adjustment mechanism, when the electric push rod is set to push directly, the electric push rod will be subjected to the reaction force exerted by the steel structure, and this radial force greatly affects the service life of the electric push rod.

[0075] In this embodiment, preferably, the second adjustment mechanism includes two inclined slots 61, two second connecting rods 62 matched with the inclined slots 61, and two horizontally arranged through slots 51 located on the same straight line, the two inclined slots 61 gradually move away from each other along the length direction, the through slots 51 are arranged on the top surface of the third support plate 5, and the two second connecting rods 62 respectively pass through the two through slots 51 and are fixedly connected to the two first support plates 2;

[0076] The inclined slot 61 can move horizontally to drive the two second connecting rods 62 to move closer to each other or away from each other.

[0077] The horizontally arranged through slot 51 restricts the second connecting rod 62 to move only in the horizontal direction. Therefore, with the movement of the inclined slot 61, the intersection of the inclined slot 61 and the through slot 51 will approach or move away from each other, thereby achieving the purpose of driving the two first support plates 2 to approach or move away from each other.

[0078] Driven by the first support plates 2, when the two first support plates 2 are brought closer to each other, the support length of the support structure will become smaller, or even be stored eventually; when the two first support plates 2 are moved away from each other, the support length of the support structure will become larger.

[0079] In this embodiment, preferably, the second adjustment mechanism is disposed in the third support plate 5 , and the second adjustment mechanism also includes a sliding plate 63 and a driving mechanism, the driving mechanism is connected to the sliding plate 63 to drive the sliding plate 63 to move horizontally, and the inclined groove 61 is disposed on the sliding plate 63 .

[0080] The horizontal movement of the inclined slot 61 can be achieved by pushing the sliding plate 63 to do reciprocating motion through the driving mechanism. The ends of the two inclined slots 61 that are close to each other are set at a position away from the driving mechanism. When the driving mechanism pushes the sliding plate 63 to move forward, the two second connecting rods 62 move away from each other, and the two first support plates 2 are also pushed to a farther position. When the driving mechanism pulls the sliding plate 63 to move backward, the two second connecting rods 62 move closer to each other, and the two first support plates 2 are also retracted.

[0081] In this embodiment, preferably, the driving mechanism includes an electric push rod 7, a second slide groove 64 and a second slider 65 cooperating with the second slide groove 64, the electric push rod 7 is arranged outside the third support plate 5, the second slide groove 64 is arranged on the bottom surface of the third support plate 5, the top of the second slider 65 is fixedly connected to the sliding plate 63, and the electric push rod 7 is connected to the second slider 65 and pushes the second slider 65.

[0082] like Figure 4 As shown, when the electric push rod 7 is pushed out, the second slider 65 moves forward and drives the sliding plate 63 to move forward. At this time, the intersection of the inclined groove 61 and the through groove 51 is away from each other, achieving the effect of pushing the two first support plates 2 outward.

[0083] The second slide groove 64 limits the movement direction of the second slider 65 , thereby avoiding radial force on the electric push rod 7 during the movement of the second slider 65 , thereby increasing the service life of the electric push rod 7 .

[0084] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0085] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction.
