Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hoisting of building steel structures, in particular to a precise positioning hoisting device for building steel structures and a use method thereof. BACKGROUND

[0002] I-beam, as a commonly used building steel structure material, is widely used in large structure construction, such as bridges, high-rise buildings, etc. Since I-beams usually need to be welded or assembled on the construction site to form complex spatial structures. Therefore, during the assembly process, the I-beam needs to be accurately lifted and fixed for the next construction operation.

[0003] For example, the patent application with publication number CN222249677U discloses a steel structure hoisting frame. The support assembly cooperates with the first and second hangers to facilitate the hoisting process of the steel structure. When the steel structure needs to be hoisted, the support assembly is first fixed at the position where the steel structure needs to be hoisted, and then the hanger is moved by the driving vehicle to lift the steel structure and transfer it to the target position. The limiting block can effectively prevent the hanger from moving too far, ensuring the safety and stability of the hoisting process.

[0004] The first and second hangers in the above-mentioned prior art can also be used in cooperation with the support assembly to hoist the I-beam. However, the use of the above-mentioned prior art still has the following problems when hoisting the I-beam: 1. During the hoisting process of the I-beam, only the distance between the first and second hangers is adjusted to adjust the I-beam of different sizes, which has a small application range. In order to hoist I-beams of different thicknesses, only the first and second clamping frames are used to limit the I-beam, which cannot limit and fix I-beams of any thickness, and the I-beam is prone to shaking and falling during the hoisting process;

[0005] 2. In addition, when the I-beam is hoisted to the splicing or welding position, the first and second clamping frames need to be removed along the length direction of the I-beam. However, due to the different installation environments, when the hoisted I-beam is in contact with other steel structures at both ends, the first and second clamping frames may collide with the steel structure at the installation position when they are removed, causing the first and second clamping frames to be unable to be removed.

[0050] Embodiment one:

[0051] With reference to Figure 1 and Figure 2 A precise positioning and hoisting device for building steel structures, comprising a hoisting frame 1, a hoisting frame 2 is installed on the hoisting frame 1, and a limiting mechanism 3 for positioning and fixing the I-shaped steel is installed on the hoisting frame 1.

[0052] The limiting mechanism 3 comprises: a plurality of groups of sliding frames 31 are uniformly arranged along the length direction of the hoisting frame 1, each group of sliding frames 31 is symmetrically arranged along the width direction of the hoisting frame 1, and is arranged on the side wall of the hoisting frame 1 and is slidably arranged along the width direction of the hoisting frame 1.

[0053] A limiting frame 32 is arranged at the bottom of the sliding frame 31, a limiting block 33 is arranged on the side of the limiting frame 32 close to the hoisting frame 1, and an inclined slope matched with the I-shaped steel is arranged on the limiting block 33.

[0054] The sliding frame 31 drives the limiting frame 32 to move synchronously to the hoisting frame 1, the inclined slope limits and locks the horizontal section above the I-shaped steel, when the I-shaped steel is hoisted to the specified position, the sliding frame 31 drives the limiting frame 32 to move synchronously to the side away from the hoisting frame 1 to release the I-shaped steel.

[0055] With reference to Figure 12 The hoisting frame 1 and the limiting mechanism 3 can clamp and limit the I-shaped steel and hoist the I-shaped steel, in the limiting mechanism 3, each group of sliding frames 31 can drive the limiting frame 32 to move synchronously during the moving process, the inclined slope of the limiting frame 32 abuts against the I-shaped steel, and then the I-shaped steel can be clamped and supported in a multi-point mode, so that the I-shaped steel can be locked and limited, when the I-shaped steel is clamped between the steel structures at the mounting position, only the limiting frame 32 needs to be reset to release the I-shaped steel, that is, the possibility of collision between the limiting frame 32 and the steel structures at the mounting position when the limiting frame 32 is taken out from the two ends of the I-shaped steel is avoided.

[0056] With reference to Figure 2 and Figure 3, the lifting frame 1 is symmetrically provided with fixed protrusions along the length direction, the transmission rod 11 is rotatably installed between the fixed protrusions through bearings, the transmission rod 11 is provided with a transmission assembly 12 corresponding to each group of sliding frames 31, and the transmission assembly 12 is used for driving the sliding frames 31 to reciprocate along the width direction of the lifting frame 1.

[0057] The transmission assembly 12 comprises: an adjusting plate 121 corresponding to each group of sliding frames 31, the adjusting plate 121 is symmetrically provided with a limiting inclined surface along the width direction of the lifting frame 1, the adjusting plate 121 is provided with a linkage protrusion 122, and the transmission rod 11 penetrates through the linkage protrusion 122 and is installed on the linkage protrusion 122 in a threaded transmission mode.

[0058] A linkage frame 123 is slidingly arranged on the lifting frame 1, the linkage frame 123 is provided with a linkage block 124 matched with the limiting inclined surface near the transmission rod 11, and one end of the linkage frame 123 away from the linkage block 124 is installed on the sliding frame 31.

[0059] A reset spring rod 125 corresponding to the linkage frame 123 is installed on the lifting frame 1, and one end of the reset spring rod 125 away from the lifting frame 1 is installed on the linkage frame 123.

[0060] In specific work, the lifting frame 2 is connected with the existing lifting equipment (hoist, etc.), and then the existing lifting equipment and the lifting frame 2 are matched to drive the lifting frame 1 to move to the I-beam to be lifted, at this time, the length direction of the lifting frame 1 is parallel to the length direction of the I-beam, then the lifting frame 1 is moved above the I-beam and the bottom of the lifting frame 1 is attached to the horizontal section above the I-beam, wherein the distance between the limiting frames 32 corresponding to each group of sliding frames 31 is greater than the width of the I-beam at the starting position, so that the limiting frames 32 and the limiting blocks 33 do not collide with the horizontal section above the I-beam during the process that the lifting frame 1 is lowered and attached to the horizontal section above the I-beam.

[0061] The transmission rod 11 is driven to rotate by the existing external driving force (manual twisting, motor, etc.), the linkage protrusion 122 is driven to move by the threaded connection mode during the rotation of the transmission rod 11, the linkage protrusion 122 drives the adjusting plate 121 to move synchronously to one side of the corresponding sliding frame 31 during the movement of the linkage protrusion 122, the limiting inclined surface of the adjusting plate 121 abuts against the linkage block 124 during the movement of the adjusting plate 121, the adjusting plate 121 drives the corresponding linkage block 124 to move towards each other through the limiting inclined surface, at this time, the linkage frame 123 is driven to move towards each other by the limiting inclined surface and the linkage block 124, the reset spring rod 125 is compressed during the movement of the linkage frame 123, the sliding frame 31 is driven to move towards each other during the movement of the linkage frame 123, the limiting frame 32 is driven to move towards each other during the movement of the sliding frame 31, and the inclined surface opposite to the limiting block 33 is also synchronously moved during the movement of the limiting frame 32 corresponding to each group of sliding frames 31, until the inclined surface abuts against the side edge of the horizontal section above the I-beam.

[0062] Further, the limiting frame 32 corresponding to each set of sliding frame 31 and the limiting block 33 can cooperate to support and limit the I-beam in multiple points, ensuring the stability of the I-beam during hoisting, avoiding the I-beam from shaking and causing misplacement with the steel structure at the installation position, affecting the hoisting precision. At this time, the inclined surface of the limiting frame 32 can provide upward support force to the I-beam, and further lock and limit the I-beam.

[0063] After the existing hoisting equipment cooperates with the hoisting rack 1 to hoist the I-beam to the designated position and make the I-beam clamped between the steel structures at the installation position, at this time, the transmission rod 11 is driven in reverse by the existing external driving force. During the reverse rotation of the transmission rod 11, the linkage protrusion 122 is reset by the threaded connection, and the linkage protrusion 122 is reset to drive the adjusting plate 121 to reset synchronously. During the resetting of the adjusting plate 121, its limiting inclined surface should be separated from the linkage block 124, but because the reset spring rod 125 resets synchronously, at this time, the linkage block 124 slides synchronously on the limiting inclined surface of the adjusting plate 121. During the resetting of the adjusting plate 121, the reset spring rod 125 drives the sliding frame 31 synchronously through the linkage block 124, and the sliding frame 31 resets the limiting block 33 synchronously through the limiting frame 32, so that the limiting block 33 releases the I-beam, avoiding the possibility of collision with the steel structure at the installation position when the limiting frame 32 and the limiting block 33 are removed from both ends of the I-beam.

[0064] At this time, the I-beam is located between the steel structures at the installation position, and the hoisting rack 1 is removed from the I-beam by the external hoisting equipment. Repeating the above actions can complete the hoisting of the remaining I-beams.

[0065] In addition, because the lengths of the horizontal sections of different I-beams are different, when supporting and limiting different thicknesses or lengths of the horizontal sections of the I-beams, only the number of turns of the rotating transmission rod 11 needs to be changed to make the adjusting plate 121 move different distances, and the different moving distances of the adjusting plate 121 can change the moving distance of the linkage block 124 driven by the limiting inclined surface, so that the moving distance of the limiting frame 32 and the limiting block 33 is different, and therefore the distance between the inclined surface of the limiting block 33 and the upper horizontal section of the I-beam is variable. Therefore, the hoisting rack 1 can support and limit different specifications of I-beams by the cooperation of the limiting frame 32 and the limiting block 33.

[0066] In addition to the above, by changing the distance between the inclined surface of the limiting block 33 and the upper horizontal section of the I-beam, the inclined surface on the limiting block 33 can also support and limit I-beams with different thicknesses of horizontal sections.

[0067] Reference Figure 4The above steps can support the I-beam from above, and the locking block 14 can also press the I-beam from below, specifically, a through groove 13 is formed in the middle of the hoisting rack 1, the locking block 14 is slidably arranged in the through groove 13, a rubber pad 15 is arranged at the bottom of the locking block 14, a guide slope is formed at the top of the locking block 14, and an adjusting connecting plate 16 is slidably arranged in the through groove 13, and the transmission rod 11 is threadedly connected to the adjusting connecting plate 16 and abuts against the guide slope at the bottom of the adjusting connecting plate 16.

[0068] The locking block 14 can be reset by the existing elastic element (such as a spring, which is not shown in the figure because it is prior art) arranged on the hoisting rack 1, and the bottom of the locking block 14 is spaced apart from the bottom of the hoisting rack 1 by a sufficient distance, and in the specific implementation process, the transmission rod 11 drives the adjusting connecting plate 16 to move horizontally in the through groove 13 through the threaded connection, the adjusting connecting plate 16 drives the locking block 14 to move downward through the guide slope during the movement of the adjusting connecting plate 16, and the locking block 14 drives the rubber pad 15 to abut against the upper horizontal section of the I-beam during the downward movement of the locking block 14, and because different specifications of I-beams require different numbers of rotations of the transmission rod 11, when the transmission rod 11 rotates too many times, the locking block 14 moves downward by a large displacement, and at this time, the deformation of the rubber pad 15 can offset the height of the locking block 14, that is, the locking block 14 will not rigidly collide with the upper horizontal section of the I-beam during the downward movement of the locking block 14.

[0069] Through the above steps, the locking block 14 and the rubber pad 15 can cooperate with each other during the downward movement of the locking block 14 to press the I-beam downward, and then the locking block 14 and the limiting frame 32 can cooperate with each other during the downward pressing of the I-beam by the locking block 14 to lock and limit the I-beam, so that the I-beam cannot shake between the hoisting rack 1 during hoisting, the stability of the I-beam during hoisting is improved, and the alignment accuracy of the I-beam with the installed position steel structure during hoisting is ensured.

[0070] The hoisting rack 1 and the hoisting frame 2 can cooperate with each other to hoist the I-beam to a suitable position through an external driving force.

[0071] Referring to Figure 11 According to the length of the hoisted I-beam, the hoisting racks 1 are mutually clamped to lengthen the device length to hoist I-beams of different specifications.

[0072] According to the length of the I-beam, a proper number of hoisting racks 1 can be selected and connected end to end, the device length is increased, the number of limiting frames 32 can be increased, and then the number of clamping support points of the limiting frames 32 for the I-beam can be increased to disperse the stress of the I-beam, improve the stability of the clamping support of the hoisting rack 1 and the limiting frame 32 for the I-beam, ensure the stability of the I-beam during hoisting, and avoid shaking of the I-beam to affect the hoisting accuracy.

[0073] Referring to Figure 5 And Figure 6 The lifting frame 1 is provided with a connecting groove 17 at one end, and a connecting protrusion 18 is arranged at the end of the lifting frame 1 away from the connecting groove 17. A limiting groove 181 is arranged on the connecting protrusion 18 (see Figure 9 A limiting rod 19 is arranged at the end of the lifting frame 1 close to the connecting groove 17 and matched with the limiting groove 181.

[0074] The driving rod 11 is provided with a tapered groove 111 at the end close to the connecting groove 17, and a plurality of arc protrusions 112 are arranged uniformly along the circumference of the tapered groove 111. The end of the driving rod 11 away from the tapered groove 111 is provided with a tapered protrusion 113 (see Figure 10 The tapered protrusion 113 is also provided with a plurality of arc protrusions 112 uniformly along the circumference.

[0075] In specific work, a proper number of lifting frames 1 are selected and connected end to end, that is, the connecting protrusion 18 is inserted into the adjacent connecting groove 17, and then the limiting rod 19 is inserted into the limiting groove 181. The adjacent lifting frames 1 are fixed by the mutual cooperation of the limiting rod 19 and the connecting protrusion 18, and the number of supporting points of the I-beam clamped by the limiting frame 32 is increased to disperse the stress of the I-beam and improve the stability of the I-beam clamped and supported by the cooperation of the lifting frame 1 and the limiting frame 32.

[0076] During the connection of the lifting frames 1, the tapered protrusion 113 on the driving rod 11 is inserted into the tapered groove 111 of the adjacent driving rod 11, and the arc protrusions 112 on the tapered protrusion 113 are staggered with the arc protrusions 112 in the tapered groove 111. During the rotation of the driving rod 11, the arc protrusions 112 on the tapered protrusion 113 are blocked by the arc protrusions 112 in the tapered groove 111, and the adjacent driving rods 11 remain relatively stationary under the cooperation of the arc protrusions 112. After rotating any driving rod 11, the remaining driving rods 11 can be driven to rotate through the cooperation of the tapered protrusion 113 and the arc protrusion 112, thereby reducing the tediousness of rotating the driving rods 11 one by one.

[0077] Referring to Figure 7In order to reduce the cumbersome of the limiting rod 19, the transmission rod 11 of the present application can be inserted into the limiting groove 181 by cooperating with the lifting block 114 through the rack plate 118, specifically, the end of the transmission rod 11 close to the connecting groove 17 is provided with a gear 117, the rack plate 118 engaged with the gear 117 is slidably arranged on the lifting frame 1, the lifting block 114 is limitingly arranged on the lifting frame 1, the side of the lifting block 114 close to the rack plate 118 is provided with a guide inclined surface, and the limiting rod 19 is arranged at the bottom of the lifting block 114, the lifting block 114 is provided with a reset frame 115, and the reset frame 115 is provided with a telescopic spring rod 116, and the end of the telescopic spring rod 116 away from the reset frame 115 is arranged on the lifting frame 1.

[0078] In specific work, when the connecting protrusion 18 is clamped in the connecting groove 17, the transmission rod 11 is rotated at this time, the transmission rod 11 drives the gear 117 to rotate synchronously in the rotating process, the gear 117 drives the rack plate 118 to move in the rotating process, the rack plate 118 abuts against the guide inclined surface and drives the lifting block 114 to move downward in the moving process, the lifting block 114 drives the limiting rod 19 to be inserted into the limiting groove 181 in the moving process, the lifting block 114 drives the telescopic spring rod 116 to be compressed through the reset frame 115 at this time, and the limiting rod 19 is completely inserted into the limiting groove 181 after that, the rack plate 118 moves out of the guide inclined surface and contacts the top of the lifting block 114 at this time.

[0079] When the limiting rod 19 is completely inserted into the limiting groove 181, the rack plate 118 moves out of the guide inclined surface and contacts the top of the lifting block 114 at this time.

[0080] When the transmission rod 11 rotates and drives the adjusting plate 121 to contact the linkage block 124, the rack plate 118 always contacts the top of the lifting block 114, and the rack plate 118 always limits the limiting rod 19 through the lifting block 114, so that the limiting rod 19 is always in the locked state.

[0081] When the lifting frame 1 needs to be removed, the transmission rod 11 is reversely rotated, the rack plate 118 is reset through the gear 117, the lifting block 114 is reset synchronously through the reset frame 115 when the rack plate 118 is separated from the top of the lifting block 114, and the lifting block 114 is completely separated from the lifting frame 1 until the rack plate 118 is completely separated from the lifting block 114, the limiting rod 19 is completely removed from the limiting groove 181 at this time, the connecting protrusion 18 is separated from the connecting groove 17 at this time, and the lifting frame 1 can be removed.

[0082] In addition, with reference to Figure 12 The box type steel structure is slidably inserted between the limiting blocks 33, and the box type steel structure can also be clamped and limited by the inclined surfaces of the limiting blocks 33.

[0083] Embodiment two: review Figure 5 On the basis of embodiment one, in embodiment two, the limiting rings 4 are symmetrically arranged along the length direction of the side walls of the hoisting racks 1, and the support rods 41 are sleeved on the same side limiting rings 4.

[0084] The support rods 41 are prepared in multiple and different lengths, and are spliced after the number of the hoisting racks 1 is determined, and the support rods 41 with appropriate lengths are selected and sequentially inserted into the same side limiting rings 4, so that the support rods 41 and the limiting rings 4 can cooperate to support and limit the hoisting racks 1, thereby reducing the shaking of the hoisting racks 1, and the limiting rings 4 are made of magnetic material and the support rods 41 are made of metal material, so that the limiting rings 4 can suck the support rods 41 after the support rods 41 are inserted into the limiting rings 4, thereby avoiding the support rods 41 from sliding off the limiting rings 4.

[0085] With reference to Figure 8 And Figure 9 The locking connecting blocks 171 are slidably arranged on both sides of the connecting grooves 17, the locking grooves 172 are arranged on the connecting protrusions 18 and matched with the locking connecting blocks 171, and the connecting surfaces are arranged on the locking connecting blocks 171 and matched with the support rods 41.

[0086] The elastic telescopic rods 173 are arranged in the locking grooves 172, and the return connecting blocks 174 are arranged on the telescopic ends of the elastic telescopic rods 173 and matched with the locking connecting blocks 171.

[0087] In specific work, when the connecting protrusions 18 are inserted into the connecting grooves, the locking connecting blocks 171 are aligned with the locking grooves 172, the support rods 41 are inserted into the limiting rings 4, the support rods 41 are in contact with the connecting surfaces and push the locking connecting blocks 171 to move into the locking grooves 172, the locking connecting blocks 171 push the return connecting blocks 174 to move into the locking grooves 172 and compress the elastic telescopic rods 173, and the support rods 41 and the locking connecting blocks 171 can also cooperate to lock and limit the connecting protrusions 18.

[0088] When the number of the hoisting racks 1 needs to be changed, the support rods 41 are pulled out, the elastic telescopic rods 173 are reset to drive the return connecting blocks 174 to be reset synchronously, the return connecting blocks 174 are reset to drive the locking connecting blocks 171 to move out of the locking grooves 172, and the adjacent hoisting racks 1 are released from the limitation.

[0089] Embodiment three: with reference to Figure 11The two groups of fixing frames 21 are symmetrically arranged along the length direction of the hoisting frame 2, and each group of fixing frames 21 is evenly distributed along the length direction of the hoisting frame 2; in addition to the hoisting frame 1 on which the hoisting frame 2 is installed, the remaining hoisting frames 1 are each installed with a fixing connecting frame 22 corresponding to the fixing frame 21 on the same side, and the fixing frame 21 and the corresponding fixing connecting frame 22 are jointly installed with a traction rope 23.

[0090] The fixing frame 21 can share the gravity component of the hoisting frame 1 by cooperating with the fixing connecting frame 22 through the traction rope 23, so as to avoid the possibility of shaking of the hoisting frame 1 due to the length being too long and the gravity being too large.

[0091] Embodiment four: refer to Figures 13 to 16 The shape of the limiting block 33 can be adjusted, and when the side of the limiting block 33 in contact with the building steel structure is provided with an arc-shaped structure, the limiting block 33 can clamp and limit the circular steel structure; in addition, due to the deformability of the rubber pad 15, the rubber pad 15 can also perform compression treatment on the circular steel structure during the compression process.

[0092] In addition, the length of the limiting frame 32 is adjustable, and the limiting frame 32 comprises a fixing connecting frame 324 installed on the sliding frame 31, a sliding connecting frame 322 is slidably sleeved on the fixing connecting frame 324, a threaded hole 321 is formed in the sliding connecting frame 322, and the sliding connecting frame 322 is installed on the fixing connecting frame 324 through a limiting bolt 323.

[0093] A plurality of threaded holes 321 matched with the limiting bolt 323 are uniformly arranged on the sliding connecting frame 322 along the height direction of the sliding connecting frame 322; specifically, when it is necessary to clamp and limit the circular steel structure, the limiting bolt 323 needs to be removed, and the sliding connecting frame 322 needs to be lowered by a certain height, so that the limiting block 33 moves to the appropriate position, that is, the circular steel structure is in contact with the side of the arc-shaped structure of the limiting block 33.

[0094] In addition, although the hoisting method of the I-beam and the circular steel is described, the essence is to change the shape of the limiting block 33 and the height of the limiting block 33 to realize the hoisting of steel structures of different shapes, so it can be seen that the present application is not limited to I-beams and circular steels, as long as the shape of the limiting block 33 and the height of the limiting block 33 are changed, the present application can also clamp and limit elliptical, polygonal and other steel structures, and has a wide range of applications.

[0095] Further, the hoisting device of the present application is for clamping and hoisting a piece of steel structure, when aiming at large steel members, which are irregular structures or complex spatial structures spliced by multiple or various steel structures, it is difficult to realize hoisting operation by relying on a group of hoisting devices, based on this, the present application can also simultaneously cooperate multiple hoisting devices to realize the hoisting operation of large steel structures, and through the linkage of multiple hoisting devices, the large steel structure can be adjusted to move to a specified position.

[0096] Therefore, the present application not only aims at positioning and hoisting operation of various shapes of building steel structures alone, but also can realize hoisting operation of large steel members through the cooperation of multiple hoisting devices, and jointly link to adjust the large steel structure to move to a specified position.

[0097] Finally, with reference to Figure 15 , the present application also provides a use method of the building steel structure precise positioning and hoisting device, which comprises the following steps: S1: splicing treatment, according to the length of the I-beam, a proper number of hoisting racks 1 are spliced with each other.

[0098] S2: device opening, the limiting frame 32 is opened through the sliding frame 31, at this time, the spacing between the limiting frame 32 corresponding to each group of sliding frames 31 is greater than the width of the I-beam.

[0099] S3: clamping treatment, the transmission rod 11 is driven to rotate by the existing external driving force (human twist, motor, etc.), the transmission rod 11 rotates and drives the linkage protrusion 122 to move through the threaded connection mode, the linkage protrusion 122 moves and drives the adjusting plate 121 to move synchronously to the side of the corresponding sliding frame 31, the adjusting plate 121 moves and its limiting inclined surface abuts against the linkage block 124, the adjusting plate 121 drives the corresponding linkage block 124 to move towards each other through the limiting inclined surface, at this time, the adjusting plate 121 drives the linkage frame 123 to move towards each other through the limiting inclined surface and the linkage block 124, at this time, the return spring rod 125 is compressed, the linkage frame 123 moves towards each other and drives the sliding frame 31 to move towards each other, the sliding frame 31 moves towards each other and drives the limiting frame 32 to move towards each other, the inclined surface opposite to the limiting block 33 also moves synchronously during the movement of the limiting frame 32 corresponding to each group of sliding frames 31, until the inclined surface abuts against the side of the horizontal section above the I-beam, and then each limiting frame 32 corresponding to each group of sliding frames 31 cooperates with the limiting block 33 to support and limit the I-beam in multiple points.

[0100] S4: hoisting treatment, the I-beam is hoisted to a suitable position through the cooperation of the hoisting rack 1 and the hoisting frame 2 and the external driving force.
