Description

Technical Field

[0001] The present application relates to the technical field of grid construction, and in particular to a fast installation construction device for a steel structure large-span grid starting frame. Background Art

[0002] The steel structure large-span grid starting frame is a type of steel structure that has the advantages of light weight, high rigidity, good integrity, strong earthquake resistance and high structural safety.

[0003] The installation of the starting frame of the large-span steel structure grid is a difficult point in the entire grid construction. At present, it mainly relies on two cranes to carry out aerial docking of the two sets of starting frames assembled on the ground. First, the first crane lifts the first set of starting frames, and the lifting height of the docking end of the first set of starting frames is higher than the docking point. Then the second crane lifts the second set of starting frames, and the docking end of the second set of starting frames is located at the docking point. Then the first crane lifts the docking end of the first set of starting frames to move, so that the docking end of the first set of starting frames and the docking end of the second set of starting frames can be docked in the air.

[0004] When the first crane lifts the butt end of the first set of starting frames close to the butt end of the second set of starting frames, the butt end of the first set of starting frames is always in a shaking state due to the swing of the crane's lifting rope, which increases the difficulty of docking the butt end of the first set of starting frames with the butt end of the second set of starting frames, thereby reducing the installation efficiency of the two sets of steel structure large-span grid starting frames. Summary of the invention

[0005] In order to improve the installation efficiency of two sets of steel structure large-span grid starting frames, the present application provides a steel structure large-span grid starting frame rapid installation construction device.

[0006] The present application provides a steel structure large-span grid starting frame rapid installation construction device, which adopts the following technical solution:

[0007] A fast installation construction device for a steel structure large-span grid starting frame, comprising two sets of installation mechanisms, the two sets of installation mechanisms correspond to the two sets of starting frames one by one, and the installation mechanisms comprise a supporting assembly, a supporting assembly, an adjusting assembly and a driving assembly;

[0008] The supporting assembly is connected to the butt end of the starting frame and is used to receive the butt end of the starting frame;

[0009] The support components are provided in at least three groups and are arranged around the supporting component, and the support components include a support plate, a support column and a conversion part;

[0010] The adjustment components are provided in at least three groups and correspond to the support components one by one. The adjustment components include an adjustment tube, a first adjustment part and a second adjustment part;

[0011] There are at least three groups of driving components, which correspond to the adjusting components one by one;

[0012] in,

[0013] The support plate is arranged on the ground, one end of the adjusting tube is ball-hinged on the support plate, the support column is slidably arranged in the adjusting tube, one end of the support column is connected to the supporting assembly, and the driving assembly is arranged on the end of the adjusting tube away from the ball-hinged end thereof, and is used to drive the support column to slide in the adjusting tube;

[0014] The support column includes a support block and a support telescopic rod. A plurality of support blocks are provided and arranged one by one. Along the arrangement direction of the support blocks, both ends of the support blocks are tapered, and two adjacent support blocks are ball-jointed.

[0015] There are multiple groups of supporting telescopic rods, which are respectively arranged between two adjacent supporting blocks. The number of supporting telescopic rods in each group is at least three and they are evenly arranged around the supporting blocks. The rod body of the supporting telescopic rod is ball-hinged on the conical surface of one of the supporting blocks, and the movable end of the supporting telescopic rod is ball-hinged on the conical surface of the other supporting block.

[0016] There are multiple conversion parts, and they correspond to the supporting telescopic rods one by one. The rod cavity of the supporting telescopic rod is connected to the atmosphere. The conversion part is arranged on the rodless cavity of the supporting telescopic rod. The conversion part is used to seal the rodless cavity of the supporting telescopic rod or to make the rodless cavity of the supporting telescopic rod connected to the atmosphere.

[0017] The first adjusting part and the second adjusting part are both arranged on the adjusting tube, the first adjusting part is arranged close to the driving assembly and is used to adjust the conversion part to seal the rodless cavity supporting the telescopic rod, and the second adjusting part is arranged away from the driving assembly and is used to adjust the conversion part to make the rodless cavity supporting the telescopic rod communicate with the atmosphere;

[0018] When all the rodless cavities supporting the telescopic rods between two adjacent support blocks are in a sealed state, the two adjacent support blocks are in a rigidly connected state. When all the rodless cavities supporting the telescopic rods between two adjacent support blocks are in a state connected to the atmosphere, the two adjacent support blocks are in a free swinging state.

[0019] By adopting the above technical scheme, when docking the two sets of starting frames, the supporting assembly is first connected to the docking end of the starting frame, and then the crane lifts the starting frame. The driving assembly drives the support column to slide in the adjusting tube. Before the support column slides out of the end of the adjusting tube away from its own hinged end, the first adjusting part can drive the conversion part to seal the rodless cavity supporting the telescopic rod, so as to adjust the two adjacent support blocks to be in a rigid connection state, so that the support column can provide a rigid supporting force to the supporting assembly. Before the support column slides out of the end of the adjusting tube close to its own hinged end, the second adjusting part can drive the conversion part to make the rodless cavity supporting the telescopic rod conductive to the atmosphere, so as to adjust the two adjacent support blocks to be in a free swinging state, so as to facilitate the sliding support column to be coiled and placed, so that the support column can automatically adjust the state of the part that slides out of the adjusting tube.

[0020] The support column rigidly supports the supporting assembly and rigidly drives the supporting assembly to move, so that the docking end of the starting frame can stably move and dock in the air. The rigid driving of the starting frame by the supporting assembly makes it difficult for the two sets of starting frames to shake when docking in the air, thereby realizing the rapid installation of the two sets of starting frames and improving the installation efficiency of the two sets of steel structure large-span grid starting frames.

[0021] Optionally, the conversion unit includes:

[0022] The conversion sleeve is connected to the rod body supporting the telescopic rod, and a conical conversion groove is provided at a position of the rod body supporting the telescopic rod corresponding to the conversion sleeve;

[0023] The rubber block is slidably arranged in the conversion sleeve and has an interference fit with the conversion sleeve. The rubber block is provided with an air hole connecting the atmosphere and the conversion groove;

[0024] The conversion block is located in the rodless cavity supporting the telescopic rod and is arranged opposite to the conversion slot, and the conversion block is adapted to the conversion slot;

[0025] A conversion spring is connected between the conversion block and the rod body supporting the telescopic rod, and the conversion spring is used to drive the conversion block to be inserted into the conversion slot;

[0026] A push rod is arranged between the rubber block and the conversion block, the push rod is connected to the rubber block, and is used to push the conversion block out of the conversion groove.

[0027] By adopting the above technical solution, the rubber block slides away from the conversion block, and the conversion block can be inserted into the conversion groove under the drive of the conversion spring. Since the conversion groove is conical, the conversion block is inserted in the conversion groove, which makes it difficult for the supporting telescopic rod to shrink, thereby making the rigid support effect between two adjacent supporting blocks stable and reliable; the rubber block slides close to the conversion block, and the rubber block drives the push rod to push the conversion block out of the conversion groove to open the conversion groove. The push rod leaves a distance between the rubber block and the conversion block, so that the air holes on the rubber block can conduct the atmosphere and the inside of the rodless cavity of the supporting telescopic rod, so that the supporting telescopic rod can be freely extended and retracted, and then the state of the supporting telescopic rod can be adjusted by adjusting the position of the rubber block.

[0028] Optionally, the first adjustment part includes a magnetic block and an iron sheet. At least three magnetic blocks are arranged along the circumference of the adjustment tube and are all embedded in the inner wall of the adjustment tube. The magnetic blocks correspond one-to-one to any group of rubber blocks on the supporting telescopic rods. There are multiple iron sheets, which correspond one-to-one to the rubber blocks. The iron sheet is connected to the end of the rubber block away from the top rod, and the air hole passes through the iron sheet.

[0029] By adopting the above technical solution, when the supporting telescopic rod moves over the magnetic block, the magnetic block can magnetically drive the iron sheet to move in a direction close to itself, and the iron sheet drives the rubber block to move, so that the conversion block can be inserted into the conversion groove under the drive of the conversion spring, thereby making it easy for the rodless cavity supporting the telescopic rod to switch to a sealed state.

[0030] Optionally, the second adjustment part includes at least three adjustment blocks, all of which are connected to the inner wall of the adjustment tube along the circumference of the adjustment tube, the adjustment blocks correspond one-to-one to the rubber blocks on any group of supporting telescopic rods, and the supporting blocks are provided with clearance grooves for the adjustment blocks to pass through, and the adjustment blocks are used to squeeze the rubber blocks so that the top rod pushes the conversion blocks out of the conversion grooves.

[0031] By adopting the above technical solution, when the supporting telescopic rod moves past the adjusting block, the hemispherical adjusting block can be squeezed on the rubber block, and the adjusting block squeezes the rubber block to slide close to the conversion block, so that the top rod pushes the conversion block out of the conversion groove, so that the air hole can connect the rodless cavity supporting the telescopic rod and the atmosphere, thereby making it easy for the rodless cavity supporting the telescopic rod to switch to a state connected to the atmosphere.

[0032] Optionally, the driving assembly includes a transmission gear and a transmission rack. A plurality of transmission gears are arranged along the sliding direction of the support column and are rotatably connected to the adjusting tube. The transmission gear extends into the adjusting tube. A plurality of transmission racks are arranged and are embedded in the support block one by one. The transmission rack is used to mesh with the transmission gear. At the same time, at least one transmission gear is in meshing state with the transmission rack. An intermediate gear is meshed between two adjacent transmission gears. The intermediate gear is rotatably connected to the adjusting tube. One of the transmission gears is connected to a driving motor, and the driving motor is installed on the adjusting tube.

[0033] By adopting the above technical solution, when driving the support column, the driving motor is started, the driving motor drives the transmission gear to rotate, the transmission gear drives the intermediate gear to rotate, and the intermediate gear drives another transmission gear that is meshed with itself to rotate. Under the transmission action of the intermediate gear, the rotation direction of all the transmission gears can be kept consistent. Since there is always a transmission gear meshing with the transmission rack, the space between two adjacent support blocks is not easy to affect the drive between the transmission gear and the transmission rack, so that the transmission rack can drive the support block to slide under the drive of the transmission gear, so that the support column can increase or decrease the length of its own rigid support part under the drive of the driving motor, and then the support column can conveniently drive the docking end of the starting frame to move stably in the air.

[0034] Optionally, each of the support blocks is engraved with a number, and along the direction away from the supporting assembly, the number on the rear support block is equal to the number on the front support block plus one, and the number on the support block closest to the supporting assembly is one.

[0035] By adopting the above technical solution, since the length of each support block is fixed, the supporting length of the support column to the support plate can be quickly and accurately known through the numbers on the support block, so that the user can adjust the supporting length of the support column.

[0036] Optionally, the supporting assembly includes a supporting plate, a connecting telescopic rod, a clamp and an adjusting part, the supporting plate is connected to the support column, at least three connecting telescopic rods are provided, the rod body of the connecting telescopic rod is ball-hinged on the supporting plate, at least three clamps are provided, and the globes are one-to-one hinged on the movable ends of the connecting telescopic rods, the clamps are used to connect the starting frame, at least three adjusting parts are provided, and they are one-to-one correspondingly arranged on the connecting telescopic rods, and the adjusting part is used to adjust and fix the length of the connecting telescopic rod.

[0037] By adopting the above technical solution, when supporting the starting frame, the telescopic rod is swung and the angle of the telescopic rod is adjusted so that the clamp can be adaptively fixed to the starting frame. The adjusting part fixes the length of the telescopic tube so that the starting frame and the supporting plate are fixed. On the one hand, the supporting connection of the starting frame is realized, and on the other hand, the supporting plate can accommodate starting frames of different sizes, thereby improving the use range of the installation construction device.

[0038] Optionally, the regulating part includes a connecting pipe and a switching valve, one end of the connecting pipe is connected to the rodless cavity connected to the telescopic rod, and the other end is connected to the rod cavity connected to the telescopic rod, hydraulic oil flows through the rodless cavity and the rod cavity connecting the telescopic rod through the connecting pipe, and the switching valve is arranged on the connecting pipe and is used to block the flow of hydraulic oil in the connecting pipe.

[0039] By adopting the above technical solution, after the clamp is connected to the starting frame, the switch valve is closed, and the switch valve can block the flow of hydraulic oil in the connecting pipe, making it difficult for hydraulic oil to flow between the rodless cavity and the rod cavity of the telescopic rod, so that the connected telescopic rod can be in a fixed length state, thereby achieving the fixation of the starting frame and the supporting plate.

[0040] Optionally, a storage assembly is provided on the support plate, the storage assembly includes a storage cylinder, a telescopic sleeve and a storage motor, one end of the storage cylinder is connected to the support plate, the telescopic sleeve is located in the storage cylinder and has one end rotatably connected to the support plate, the storage motor is located in the storage cylinder and is slidably connected to the storage cylinder in a direction approaching or moving away from the support plate, the output shaft of the storage motor is connected to the end of the telescopic sleeve away from the support plate, the support column is slidably penetrated into a storage hole opened on the bottom side wall of the storage cylinder, one end of the support column away from the supporting assembly is fixedly connected to the end of the telescopic sleeve close to the storage motor, the part of the support column located between the storage cylinder and the telescopic sleeve is spirally wound on the telescopic sleeve, and the space between the storage cylinder and the telescopic sleeve limits the spiral structure of the support column to be a single-layer spiral structure.

[0041] By adopting the above technical solution, the storage motor drives the telescopic sleeve to rotate, and the telescopic sleeve can drive the support shaft to spirally wrap around itself so that the support column can be spirally coiled and stored, saving the placement space of the support column and facilitating the use of the support column at the construction site; because the space between the storage cylinder and the telescopic sleeve can limit the support column to a single-layer spiral structure, when the support column slides out of the storage cylinder, the storage motor can drive the telescopic sleeve to contract under the action of its own weight to lower its own height. Therefore, during use, the center of gravity of the storage cylinder, telescopic sleeve and storage motor as a whole will gradually decrease, making it less likely that the support point of the support column and the ground will be offset.

[0042] Optionally, the storage assembly also includes a connecting plate and a fixed drill rod, one side of the connecting plate is connected to the output shaft of the storage motor, and the other side of the connecting plate is connected to the telescopic sleeve. A slider is connected to the connecting plate, and the slider is slidably set in a spiral groove opened on the inner wall of the storage tube. The fixed drill rod is located in the telescopic sleeve and connected to the connecting plate. The fixed drill rod is slidably passed through a fixed hole opened in the support plate, and the fixed drill rod is used for drilling in the formation.

[0043] By adopting the above technical solution, when the storage motor drives the support column to slide out of the storage cylinder, the connecting plate can drive the slider to slide in the spiral groove under the drive of the storage motor, and the connecting plate can drive the fixed drill rod to rotate. Under the guidance restriction of the spiral groove, the connecting plate moves toward the support plate, and with the assistance of the storage motor's own weight, the fixed drill rod can be drilled into the formation. Therefore, during use, the depth of the fixed drill rod drilling into the formation can increase with the increase of the length of the support column sliding out of the storage cylinder, further making it less likely for the support point of the support column and the ground to shift.

[0044] In summary, the present application includes at least one of the following beneficial technical effects:

[0045] 1. By arranging a support block, a support telescopic rod, a conversion sleeve, a rubber block, a conversion block, a conversion spring, a top rod, and opening air holes on the rubber block, the support column formed by the support block and the support telescopic rod can be switched between rigid support and swing bending. By adjusting the rigid support length of at least three support columns, the butt end of the starting frame can be rigidly driven to move stably, thereby improving the installation efficiency of the two sets of steel structure large-span grid starting frames;

[0046] 2. By setting the adjusting tube, the magnetic block, the iron sheet and the adjusting block, the supporting column can automatically adjust the connection state of two adjacent supporting blocks when sliding in the adjusting tube;

[0047] 3. By providing a storage cylinder, a telescopic sleeve, a storage motor, a connecting plate, a slider, a fixed drill rod and opening a spiral groove on the inner wall of the storage cylinder, the swinging and bending parts of the support column can be easily stored together, and the support plate is not easily offset from the ground.

DETAILED DESCRIPTION

[0060] The following is combined with Figure 1-10 This application is described in further detail.

[0061] The present application embodiment discloses a steel structure large span grid starting frame rapid installation construction device. Figure 1A fast installation construction device for a steel structure large-span grid starting frame includes two sets of installation mechanisms 1, and the two sets of installation mechanisms 1 correspond to the two sets of starting frames one by one. The installation mechanism 1 includes a supporting component 2, a supporting component 3, an adjusting component 4, a driving component 5 and a storage component 6. The supporting component 2 is used to receive the docking end of the starting frame. The supporting component 3 has two use states. The first use state of the supporting component 3 is a rigid support state for supporting the supporting component 2. The second use state of the supporting component 3 is a swing bending state for centralized storage. The two use states of the supporting component 3 can exist at the same time. , that is, part of the support component 3 is in the first use state, and the other part is in the second use state. The adjustment component 4 is used to adjust the two use states of the support component 3, so that part of the support component 3 provides rigid support to the supporting component 2, and the other part of the support component 3 can be stored. Under the adjustment action of the adjustment component 4, the part of the support component 3 in the rigid support state can be adjusted according to needs. The driving component 5 is used to drive the part of the support component 3 in the rigid support state to move, and the storage component 6 is used to centrally store the part of the support component 3 in the swinging and bending state.

[0062] When docking two sets of starting frames, first connect the supporting component 2 to the docking end of the starting frame, then lift the starting frame with a crane, adjust the part of the supporting component 3 in a rigid supporting state by the adjusting component 4, the part of the supporting component 3 in a rigid supporting state provides supporting force to the supporting component 2, and drives the supporting component 2 to move, drive the supporting component 3 in a rigid supporting state to move, so that the supporting component 3 can drive the supporting component 2 to carry the docking end of the starting frame for aerial docking, and the storage component 6 stores the part of the supporting component 3 in a swinging and bending state, so that the part of the supporting component 3 in a rigid supporting state can be more retreated and less supplemented, thereby, through the rigid drive of the starting frame by the supporting component 3, the two sets of starting frames are not prone to shaking when docking in the air, thereby realizing the rapid installation of the two sets of starting frames and improving the installation efficiency of the two sets of steel structure large-span grid starting frames.

[0063] In this application, reference is made to Figure 2 The supporting assembly 2 includes a supporting plate 21, a connecting telescopic rod 22, a clamp 23 and an adjusting part 24. The supporting plate 21 is located below the docking end of the starting frame; four connecting telescopic rods 22 are provided, and are evenly arranged around the central axis direction of the supporting plate 21, and the rod body of the connecting telescopic rod 22 is ball-hinged on the supporting plate 21; four clamps 23 are provided, and are one-to-one correspondingly spherically hinged on the movable end of the connecting telescopic rod 22, and the clamp 23 is used to be fixed on the starting frame; four adjusting parts 24 are provided, and are one-to-one correspondingly arranged on the connecting telescopic rod 22, and the adjusting part 24 is used to adjust and fix the length of the connecting telescopic rod 22.

[0064] When supporting the starting frame, the telescopic rod 22 is swung and the angle of the telescopic rod 22 is adjusted so that the clamp 23 can be adaptively fixed to the starting frame. The regulating part 24 fixes the length of the telescopic tube so that the starting frame and the supporting plate 21 are fixed. On the one hand, the supporting connection of the starting frame is realized, and on the other hand, the supporting plate 21 can accommodate starting frames of different sizes, thereby improving the use range of the installation construction device.

[0065] Specifically, refer to Figure 2 The regulating part 24 includes a connecting pipe 241 and a switch valve 242. One end of the connecting pipe 241 is connected to the rodless cavity connected to the telescopic rod 22, and the other end is connected to the rod cavity connected to the telescopic rod 22. Hydraulic oil flows through the rodless cavity and the rod cavity connecting the telescopic rod 22 through the connecting pipe 241. The switch valve 242 is set on the connecting pipe 241 and is used to block the flow of hydraulic oil in the connecting pipe 241.

[0066] After the clamp 23 is connected to the starting frame, the switch valve 242 is closed. The switch valve 242 can block the flow of hydraulic oil in the connecting pipe 241, making it difficult for hydraulic oil to flow between the rodless cavity and the rod cavity of the telescopic rod 22, so that the telescopic rod 22 can be in a fixed length state, thereby achieving the fixation of the starting frame and the supporting plate 21.

[0067] In this application, reference is made to Figure 1 and Figure 3 The support assembly 3 is provided with three groups and is evenly arranged around the support plate 21. The support assembly 3 includes a support plate 31, a support column 32 and a conversion portion 33. Due to the complex structure of the support column 32, in order to better display, a round rod is used. Figure 1 The support column 32 is shown in FIG.

[0068] The support plate 31 is placed on the ground to form a support force point for the support plate 21. One end of the support column 32 is ball-hinged on the support plate 21, and the support column 32 includes a support block 321 and a support telescopic rod 322. There are multiple support blocks 321, which are arranged one by one. Along the arrangement direction of the support blocks 321, both ends of the support blocks 321 are tapered, and two adjacent support blocks 321 are ball-hinged so that the two adjacent support blocks 321 can swing in any direction.

[0069] Reference Figure 3There are multiple groups of supporting telescopic rods 322, and they are respectively arranged between two adjacent support blocks 321. The number of supporting telescopic rods 322 in each group is three, and they are evenly arranged around the support block 321. The rod body of the supporting telescopic rod 322 is ball-hinged on the conical surface of one of the support blocks 321, and the movable end of the supporting telescopic rod 322 is ball-hinged on the conical surface of another support block 321. When the supporting telescopic rod 322 is in a telescopic state, two adjacent support blocks 321 can swing, so that the support column 32 can be in a swinging and bending state. When the supporting telescopic rod 322 is in a fixed length state, it is in a fixed state between two adjacent support blocks 321, so that the support column 32 can be in a rigid support state.

[0070] Reference Figure 4 There are multiple conversion parts 33, and they correspond one to one with the supporting telescopic rods 322. The rod cavity of the supporting telescopic rod 322 is connected to the atmosphere. The conversion part 33 is set on the rodless cavity of the supporting telescopic rod 322. The conversion part 33 is used to seal the rodless cavity of the supporting telescopic rod 322 or to make the rodless cavity of the supporting telescopic rod 322 conductive to the atmosphere. The conversion part 33 enables the supporting telescopic rod 322 to switch between a telescopic state and a fixed length state. When all the rodless cavities of the supporting telescopic rods 322 between two adjacent support blocks 321 are in a sealed state, the two adjacent support blocks 321 are in a rigid connection state. When all the rodless cavities of the supporting telescopic rods 322 between two adjacent support blocks 321 are in a state of communication with the atmosphere, the two adjacent support blocks 321 are in a free swinging state.

[0071] When a supporting force is applied to the support plate 21, under the action of the conversion part 33, the support column 32 formed by the support block 321 and the supporting telescopic rod 322 can switch between a rigid supporting state and a swinging bending state. The conversion part 33 seals the rodless cavity of the supporting telescopic rod 322, so that the support column 32 can provide a supporting force to the support plate 21 in a rigid supporting state, so that the support plate 21 can rigidly and stably move the docking end of the starting frame. The conversion part 33 makes the rodless cavity of the supporting telescopic rod 322 conductive to the atmosphere, so that the support column 32 can be stored in a swinging bending state, so that the support column 32 can save placement space, thereby making it easy to adjust the supporting length of the support column 32 for the support plate 21 according to actual conditions. With the joint cooperation of the three groups of support components 3, the rigid supporting length of the support column 32 is adjusted, so that the docking end of the starting frame can be stably moved in the air.

[0072] Specifically, refer to Figure 5 The conversion part 33 includes a conversion sleeve 331 , a rubber block 332 , a conversion block 333 , a conversion spring 334 and a push rod 335 .

[0073] The conversion sleeve 331 is connected to the rod body supporting the telescopic rod 322, and a conical conversion groove 3221 is provided on the rod body supporting the telescopic rod 322 at a position corresponding to the conversion sleeve 331. The rubber block 332 is slidably arranged in the conversion sleeve 331 and has an interference fit with the conversion sleeve 331. Two air holes 3321 connecting the atmosphere and the conversion groove 3221 are symmetrically provided on the rubber block 332. The conversion block 333 is located in the rodless cavity supporting the telescopic rod 322 and is arranged opposite to the conversion groove 3221. The conversion block 333 is adapted to the conversion groove 3221. The conversion spring 334 is fixedly connected between the conversion block 333 and the rod body supporting the telescopic rod 322, and the conversion spring 334 is used to drive the conversion block 333 to be inserted into the conversion groove 3221. The push rod 335 is disposed between the rubber block 332 and the conversion block 333 . The push rod 335 is fixedly connected to the rubber block 332 . The push rod 335 is used to push the conversion block 333 out of the conversion groove 3221 .

[0074] Further, refer to Figure 5 A sliding block 3322 is fixedly connected to the rubber block 332. The sliding block 3322 is slidably arranged in a sliding groove 3311 provided on the inner wall of the conversion sleeve 331. The sliding groove 3311 guides the sliding direction of the sliding block 3322 to be close to or away from the conversion block 333. The sliding groove 3311 limits the sliding stroke of the sliding block 3322, so that the rubber block 332 is not easy to fall out of the conversion sleeve 331, thereby making the rubber block 332 not easy to be lost during use.

[0075] Furthermore, refer to Figure 1 and Figure 6 , each support block 321 is engraved with a number 3212. Along the direction away from the supporting component 2, the number 3212 on the rear support block 321 is equal to the number 3212 on the front support block 321 plus one, and the number 3212 on the support block 321 closest to the supporting component 2 is one. Since the length of each support block 321 is fixed, the number 3212 on the support block 321 can be used to quickly and accurately know the supporting length of the support column 32 for the supporting plate 21, so that the user can adjust the supporting length of the support column 32.

[0076] When the supporting telescopic rod 322 is switched to a fixed length state, the rubber block 332 slides off the conversion block 333, and the conversion block 333 can be inserted into the conversion slot 3221 under the drive of the conversion spring 334. Since the conversion slot 3221 is conical, the conversion block 333 is inserted into the conversion slot 3221, making it difficult for the supporting telescopic rod 322 to shrink, thereby making the rigid support effect between the two adjacent supporting blocks 321 stable and reliable; when the supporting telescopic rod 322 is switched to a telescopic state, the rubber block 332 The conversion block 333 is slid closer, and the rubber block 332 drives the push rod 335 to push the conversion block 333 out of the conversion slot 3221 to open the conversion slot 3221. The push rod 335 leaves a distance between the rubber block 332 and the conversion block 333, so that the air hole 3321 on the rubber block 332 can conduct the atmosphere and the inside of the rodless cavity of the supporting telescopic rod 322, so that the supporting telescopic rod 322 can be freely extended and retracted, and then the state of the supporting telescopic rod 322 can be adjusted by adjusting the position of the rubber block 332.

[0077] In this application, reference is made to Figure 1 , Figure 6 and Figure 7 The adjusting assembly 4 is provided with three groups, and corresponds to the supporting assembly 3 one by one. The adjusting assembly 4 includes an adjusting tube 41, a first adjusting part 42 and a second adjusting part 43. One end of the adjusting tube 41 is ball-hinged on the supporting plate 31, the supporting column 32 is slidably penetrated in the adjusting tube 41, and the supporting block 321 is adapted to the adjusting tube 41. The first adjusting part 42 and the second adjusting part 43 are both arranged on the adjusting tube 41. The first adjusting part 42 is arranged away from the hinged end of the adjusting tube 41, and is used to adjust the rubber block 332 to seal the rodless cavity supporting the telescopic rod 322. The second adjusting part 43 is arranged close to the hinged end of the adjusting tube 41, and is used to adjust the rubber block 332 to make the rodless cavity supporting the telescopic rod 322 conductive with the atmosphere.

[0078] The support column 32 is made to slide in the adjustment tube 41. Before the support column 32 slides out from the end of the adjustment tube 41 away from its own hinged end, the first adjustment part 42 can drive the rubber block 332 to seal the rodless cavity supporting the telescopic rod 322, so as to adjust the two adjacent support blocks 321 to be in a rigid connection state, so that the sliding support column 32 can provide a rigid supporting force to the support plate 21; before the support column 32 slides out from the end of the adjustment tube 41 close to its own hinged end, the second adjustment part 43 can drive the rubber block 332 to make the rodless cavity supporting the telescopic rod 322 conductive to the atmosphere, so as to adjust the two adjacent support blocks 321 to be in a free swinging state, so that the sliding support column 32 can be coiled and placed, so that the support column 32 can automatically adjust the state of the part that slides out from the adjustment tube 41, so that the support column 32 can provide rigid support and be placed easily, and the rigid support length of the support column 32 can be easily adjusted.

[0079] Further, refer to Figure 3 The ball hinge structure of the adjusting tube 41 and the support plate 31 includes a hinge ball 411, a hinge ring 412 and a connecting seat 413. The hinge ball 411 is fixedly mounted on the end of the adjusting tube 41, and the hinge ring 412 is mounted on the hinge ball 411. The hinge ball 411 and the hinge ring 412 are rotatably connected in any direction. One end of the connecting seat 413 is fixedly connected to the hinge ring 412, and the other end is fixedly connected to the support plate 31. Therefore, through the hinge ball 411 and the hinge ring 412, a ball hinge connection relationship can be formed between the adjusting tube 41 and the support plate 31.

[0080] Furthermore, refer to Figure 3 The hinge ring 412 is tilted so that the adjustment tube 41 can swing from a horizontal state to a vertical state, so that the support direction of the support column 32 can change from horizontal to vertical, so that the support column 32 can meet the angle requirements for starting and moving in the air.

[0081] Specifically, refer to Figure 5 and Figure 6 The first adjusting part 42 includes a magnetic block 421 and an iron sheet 422. Three magnetic blocks 421 are arranged along the circumference of the adjusting tube 41 and are fixedly embedded in the inner wall of the adjusting tube 41. The magnetic blocks 421 correspond one-to-one to any group of rubber blocks 332 on the supporting telescopic rods 322. There are multiple iron sheets 422, which correspond one-to-one to the rubber blocks 332. The iron sheet 422 is fixedly connected to one end of the rubber block 332 away from the top rod 335, and the air hole 3321 runs through the iron sheet 422.

[0082] When the supporting telescopic rod 322 moves past the magnetic block 421, the magnetic block 421 can magnetically drive the iron sheet 422 to move in a direction close to itself, and the iron sheet 422 drives the rubber block 332 to move, so that the conversion block 333 can be inserted into the conversion slot 3221 under the drive of the conversion spring 334, so that the supporting telescopic rod 322 can be easily switched to a fixed length state.

[0083] Specifically, refer to Figure 5 and Figure 7 The second adjusting portion 43 includes three hemispherical adjusting blocks 431. All the adjusting blocks 431 are fixedly connected to the inner wall of the adjusting tube 41 along the circumference of the adjusting tube 41. The adjusting blocks 431 correspond one-to-one to the rubber blocks 332 on any group of supporting telescopic rods 322. The supporting blocks 321 are provided with a clearance groove 3211 for the adjusting blocks 431 to pass through, so that the adjusting blocks 431 are not easy to interfere with the sliding of the supporting blocks 321 in the adjusting tube 41. The adjusting blocks 431 are used to squeeze the rubber blocks 332 so that the top rod 335 pushes the conversion block 333 out of the conversion groove 3221.

[0084] When the supporting telescopic rod 322 moves past the adjusting block 431, the hemispherical adjusting block 431 can be squeezed on the iron sheet 422 set on the rubber block 332, and the adjusting block 431 squeezes the iron sheet 422, the rubber block 332 and the push rod 335 to form an integral sliding conversion block 333, so that the push rod 335 pushes the conversion block 333 out of the conversion groove 3221, so that the air hole 3321 can connect the rodless cavity of the supporting telescopic rod 322 and the atmosphere, so that the supporting telescopic rod 322 can be easily switched to a freely telescopic state.

[0085] In this application, reference is made to Figure 3 and Figure 8 There are three groups of drive components 5, which correspond to the adjustment components 4 one by one. The drive components 5 are arranged on the end of the adjustment tube 41 away from the ball hinge thereof. The drive components 5 include a transmission gear 51 and a transmission rack 52.

[0086] There are multiple transmission gears 51 along the sliding direction of the support column 32, and they are all rotatably connected to the adjustment tube 41, and the transmission gear 51 penetrates into the adjustment tube 41. There are multiple transmission racks 52, and they are fixedly embedded in the support block 321 in a one-to-one correspondence. The transmission racks 52 are used to mesh with the transmission gears 51. At the same time, at least one transmission gear 51 is in a meshing state with the transmission rack 52. An intermediate gear 53 is meshed between two adjacent transmission gears 51, and the intermediate gear 53 is rotatably connected to the adjustment tube 41. One of the transmission gears 51 is connected to a drive motor 54, and the drive motor 54 is fixedly connected to the adjustment tube 41, and the output shaft of the drive motor 54 is fixedly connected to the transmission gear 51.

[0087] When driving the support column 32, the drive motor 54 is started, the drive motor 54 drives the transmission gear 51 to rotate, the transmission gear 51 drives the intermediate gear 53 to rotate, and the intermediate gear 53 drives another transmission gear 51 that is meshed with itself to rotate. Under the transmission action of the intermediate gear 53, the rotation direction of all the transmission gears 51 can be kept consistent. Since there is always a transmission gear 51 meshing with the transmission rack 52, the space between two adjacent support blocks 321 is not easy to affect the drive between the transmission gear 51 and the transmission rack 52, so that the transmission rack 52 can drive the support block 321 to slide under the drive of the transmission gear 51, so that the support column 32 can increase the length of the rigid support part or increase the length of the swinging bending part under the drive of the drive motor 54, so that the support column 32 can conveniently drive the docking end of the starting frame to move stably in the air.

[0088] In this application, reference is made to Figure 1 and Fig. 9The storage assembly 6 is provided with three groups, and corresponds to the support assembly 3 one by one. The storage assembly 6 includes a storage cylinder 61, a telescopic sleeve 62 and a storage motor 63. Due to the complex structure of the support column 32, in order to better display, a spiral soft rod is used. Fig. 9 The support column 32 is shown in FIG.

[0089] Reference Fig. 9 and Fig.10 , one end of the storage tube 61 is connected to the support plate 31. The telescopic sleeve 62 is located in the storage tube 61, and one end is rotatably connected to the support plate 31. The telescopic sleeve 62 is a multi-stage telescopic pipe, and the axis of the telescopic sleeve 62 coincides with the axis of the storage tube 61. The storage motor 63 is located in the storage tube 61, and is slidably connected to the storage tube 61 in the direction of approaching or moving away from the support plate 31, and the output shaft of the storage motor 63 is connected to the end of the telescopic sleeve 62 away from the support plate 31.

[0090] Among them, refer to Fig. 9 The storage motor 63 is fixedly connected with a slide rod 631, and both ends of the slide rod 631 are respectively slidably arranged in two slide grooves 613 symmetrically opened on the inner wall of the storage tube 61. The slide rod 631 and the slide groove 613 form a sliding connection structure between the storage motor 63 and the storage tube 61.

[0091] Reference Figure 1 and Fig. 9 The support column 32 is slidably inserted into a storage hole 611 opened on the bottom side wall of the storage tube 61, and one end of the support column 32 away from the supporting plate 21 is fixedly connected to the end of the telescopic sleeve 62 close to the storage motor 63. The part of the support column 32 located between the storage tube 61 and the telescopic sleeve 62 is spirally wound on the telescopic sleeve 62, and the space between the storage tube 61 and the telescopic sleeve 62 limits the spiral structure of the support column 32 to a single-layer spiral structure.

[0092] With regard to the swinging and bending part of the support column 32, the storage motor 63 drives the telescopic sleeve 62 to rotate, and the telescopic sleeve 62 can drive the support column 32 to spirally wrap around itself so that the support column 32 can be spirally coiled and stored, saving the placement space of the support column 32 and facilitating the use of the support column 32 at the construction site; because the space between the storage cylinder 61 and the telescopic sleeve 62 can limit the support column 32 to a single-layer spiral structure, when the support column 32 slides out of the storage cylinder 61, the storage motor 63 can drive the telescopic sleeve 62 to contract under the action of its own weight to lower its own height. Therefore, during use, the center of gravity of the storage cylinder 61, the telescopic sleeve 62 and the storage motor 63 as a whole will gradually decrease, making it less likely for the support point of the support column 32 and the ground to shift.

[0093] Further, refer to Fig. 9 and Fig.10The storage assembly 6 also includes a connecting plate 64 and a fixed drill rod 65. One side of the connecting plate 64 is fixedly connected to the output shaft of the storage motor 63, and the other side of the connecting plate 64 is fixedly connected to the telescopic sleeve 62. A circular cylindrical slider 641 is connected to the connecting plate 64, and the slider 641 is slidably set in a spiral groove 612 opened on the inner wall of the storage tube 61; the fixed drill rod 65 is located in the telescopic sleeve 62 and is fixedly connected to the connecting plate 64. The fixed drill rod 65 is slidably penetrated into the fixed hole 311 opened on the support plate 31, and the fixed drill rod 65 is used for drilling in the formation.

[0094] When the storage motor 63 drives the support column 32 to slide out of the storage tube 61, the connecting plate 64 can drive the slider 641 to slide in the spiral groove 612 under the drive of the storage motor 63, and the connecting plate 64 can drive the fixed drill rod 65 to rotate. Under the guidance restriction of the spiral groove 612, the connecting plate 64 moves toward the support plate 31. With the assistance of the deadweight of the storage motor 63, the fixed drill rod 65 can be drilled into the formation. Therefore, during use, the depth of the fixed drill rod 65 drilling into the formation can increase with the increase of the length of the support column 32 sliding out of the storage tube 61, thereby making it less likely for the support point of the support column 32 and the ground to shift.

[0095] The implementation principle of a quick installation construction device for a large-span steel structure grid starting frame in an embodiment of the present application is as follows: when in use, two sets of installation mechanisms 1 respectively support the docking ends of the two sets of starting frames, and the magnetic block 421 adjusts the supporting telescopic rod 322 to a fixed length state, so that the support column 32 applies a rigid supporting force to the docking end of the starting frame, and the rigid support length of the three support columns 32 is adjusted to drive the docking end of the starting frame to move stably in the air, so that the two sets of starting frames are not prone to shaking when docking in the air, thereby realizing the rapid installation of the two sets of starting frames and improving the installation efficiency of the two sets of steel structure large-span grid starting frames.

[0096] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
