Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hoop hoisting, in particular to a hoop hoisting equipment for bent cap construction. BACKGROUND

[0002] The bent cap hoop is a key temporary component in the construction of the bridge bent cap, and its core is to form a stable support system by closely fitting with the bridge pier. It can bear the whole process construction load of the formwork, steel reinforcement, concrete and operating personnel equipment, and can also uniformly transmit the load to the bridge pier to avoid local stress concentration. It can also replace the traditional floor support, adapt to high piers, complex geology and restricted sites, reduce construction cost and construction period, and at the same time, it can guarantee the axial line, elevation and structural size precision of the bent cap construction, prevent problems such as slipping and deformation during construction, and can also temporarily fix the steel reinforcement cage and expand the construction space to provide a safe, efficient and accurate operation basis for bent cap construction.

[0003] The patent document with publication number CN214828335U discloses a double-hoop integral hoisting structure for bent cap construction, which comprises upper and lower hoops arranged in sequence from top to bottom. The two sides of the upper hoop are provided with first connecting bodies, and the two sides of the lower hoop are provided with second connecting bodies corresponding to the first connecting bodies. The first and second connecting bodies on the same side are connected by a connecting piece. The upper end of the upper hoop is provided with a lifting device for lifting the upper hoop. The first connecting body is a first lifting ring fixed to the two sides of the upper hoop. The first lifting ring is arranged in four groups of two on the two sides of the upper hoop. The upper and lower hoops are connected as a whole, and then hoisted at one time.

[0004] However, the following problems still exist in this scheme. The core process of bent cap hoop hoisting is to slowly lower the hoop from the top of the bridge pier and set it outside the bridge pier, and then fix it with a fastening device after accurately moving to the preset installation position. However, during single-hoop hoisting, due to the large weight of the hoop, irregular left and right shaking is easily caused by the start and stop of the lifting equipment, wind interference and its own inertia during hoisting, which not only makes it difficult to accurately align the setting position of the hoop outside the bridge pier, but also requires repeated adjustment of manual auxiliary positioning, resulting in high labor intensity, safety hazards of personnel collision, greatly increased positioning time, slowed hoisting progress and affected construction efficiency.

[0005] In addition, when double-layer hoop synchronous hoisting is performed, the difficulty is further increased. Since the two layers of hoops need to be lifted synchronously, their shaking trajectories are difficult to completely coincide, which easily causes mutual interference and misalignment, significantly increasing the operation difficulty of accurately setting the two layers of hoops outside the bridge pier, further prolonging the operation time, and increasing the safety risk coefficient due to the increase in operation complexity, which has a double impact on the safety and efficiency of hoisting operations. SUMMARY

DETAILED DESCRIPTION

[0035] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0036] As Figures 1 to 11As shown, the clamp hoisting equipment for bent cap construction of the present application comprises a connecting plate 3 and a receiving frame 2, the receiving frame 2 is provided with a lifting lug 31, the lifting lug 31 is connected with a lifting rope 1, the end of the lifting rope 1 away from the lifting lug 31 is firmly hung with a lifting hook 11 of a crane, and the lower part of the receiving frame 2 is provided with a connecting rope 03 connected with a clamp 02. Two receiving frames 2 are correspondingly provided with two clamps 02, and the two receiving frames 2 are symmetrically distributed at the two ends of the connecting plate 3. After the crane is started, the receiving frame 2 is stably lifted by the lifting rope 1, and the two receiving frames 2 are kept synchronous lifting, and then the receiving frame 2 lifts the clamp 02 through the connecting rope 03, so as to realize the synchronous and stable hoisting of the two clamps 02.

[0037] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , two lifting lugs 31 are symmetrically arranged above the receiving frame 2 around its center of gravity, so as to ensure that the two lifting lugs 31 evenly share the hoisting load when the crane exerts force through the lifting rope 1. Through the symmetrical arrangement structure of the double lifting lugs 31, the situation that the receiving frame 2 tilts on one side or is unevenly stressed when being lifted is avoided, so that the receiving frame 2 always maintains a horizontal posture, and then a stable force is transmitted through the connecting rope 03, so as to ensure that the clamp 02 does not deviate or shake during the entire hoisting process, so as to facilitate subsequent assembly.

[0038] Referring to Figure 4 , Figure 5 , Figure 6 , Figure 7 , the two receiving frames 2 are respectively connected with the two ends of the connecting plate 3, the receiving frame 2 is rotationally connected with the connecting plate 3, a pushing assembly 4 and a rotating assembly 5 are arranged on the connecting plate 3, the pushing assembly 4 is matched with the rotating assembly 5, and the rotating assembly 5 is connected with the receiving frame 2 to drive the receiving frame 2 to rotate.

[0039] Before hoisting, the end of the clamp 02 away from the connecting plate 3 maintains an open posture, after the crane is started, the crane lifts the clamp 02 through the receiving frame 2 and the connecting rope 03, when the crane hoists the clamp 02 to the preset horizontal height of the pier 01, the connecting plate 3 is driven to horizontally translate to the pier 01. At the same time, the clamp 02 in the open state slowly moves along the outside of the pier 01, so as to ensure that the clamp 02 maintains a safe distance from the pier 01 and is stably sleeved into the external area of the pier 01. When the pier 01 is completely located in the middle position of the two symmetrical clamps 02, the connecting plate 3 drives the pushing assembly 4 to abut against the side surface of the pier 01. During the abutting process of the pushing assembly 4 and the pier 01, the pushing assembly 4 drives the receiving frame 2 to rotate through the rotating assembly 5, the receiving frame 2 drives the end of the clamp 02 away from the connecting plate 3 to close, so that the clamp 02 is sleeved on the outside of the pier 01, so as to facilitate subsequent fixation.

[0040] Referring to Figure 3 , Figure 5 ,Figure 6 The pushing assembly 4 comprises a sliding plate 41, a pushing plate 42, the sliding plate 41 is horizontally slidingly arranged on the connecting plate 3, and the sliding plate 41 is arranged in a horizontal direction, the sliding plate 41 slides on the connecting plate 3 in a direction towards the pier 01, the pushing plate 42 is connected to an end of the sliding plate 41 close to the pier 01, the pushing plate 42 is arranged in a vertical direction, the pushing plate 42 is located on a side of the connecting plate 3 close to the pier 01, and the sliding plate 41 and the pushing plate 42 are located between the two groups of receiving frames 2. The sliding plate 41 cooperates with the rotating assembly 5.

[0041] Initially, the two groups of receiving frames 2 are opened, the connecting plate 3 is horizontally close to the pier 01, and the pushing plate 42 is synchronously close to the pier 01, after the receiving frame 2 is gradually moved to the outside of the pier 01, the pushing plate 42 abuts against the side surface of the pier 01, the connecting plate 3 continues to move, and the sliding plate 41 moves relative to the connecting plate 3, the sliding plate 41 moves through the rotating assembly 5 to drive the receiving frame 2 to rotate, so that the hoop 02 moves towards the pier 01 while being folded, and the hoop 02 is finally folded and sleeved on the outside of the pier 01.

[0042] Referring to Figure 7 The pushing plate 42 is rotationally connected with the sliding plate 41, the rotation axis of the pushing plate 42 is arranged in a horizontal direction, and the rotation axis is perpendicular to the sliding direction of the sliding plate 41, and the pushing plate 42 is arranged in a vertical state as a whole. A torsional spring (not shown in the figure) is arranged at the connecting position of the pushing plate 42 and the sliding plate 41, and the two ends of the torsional spring are fixedly connected with the pushing plate 42 and the sliding plate 41 respectively, and the torsional spring is used to drive the pushing plate 42 to reset to a vertical state. When the pushing plate 42 abuts against the pier 01, the relative rotation cooperation between the pushing plate 42 and the sliding plate 41 enables the pushing plate 42 to be self-adapted to the side surface of the pier 01, and the position of the sliding plate 41 is accurately adjusted. In addition, the pushing plate 42 is designed in an arc structure, the inner side of the pushing plate 42 is arranged towards the pier 01, and the arc profile of the inner side of the pushing plate 42 is matched with the outer side surface of the pier 01. When the connecting plate 3 approaches the pier 01, the inner side of the pushing plate 42 can be in surface contact with the pier 01, and the arc structure design can increase the contact area, thereby effectively improving the stability of the abutment position.

[0043] Referring to Figure 5 , Figure 6 , Figure 7 The rotating assembly 5 comprises a rotating gear 51, an intermediate piece 52 and a bevel gear set 53, the rotating gear 51 is rotationally arranged in the connecting plate 3, the intermediate piece 52 is also arranged in the connecting plate 3, the intermediate piece 52 cooperates with the rotating gear 51, and the bevel gear set 53 is connected with the intermediate piece 52 and the rotating shaft of the receiving frame 2 respectively. A tooth groove 411 is formed in the sliding plate 41, the tooth groove 411 is arranged in the sliding direction of the sliding plate 41, the rotating gear 51 is engaged with the tooth groove 411, and the sliding plate 41 can drive the rotating gear 51 to rotate when the sliding plate 41 moves.

[0044] When the push plate 42 abuts against the pier 01 to drive the sliding plate 41 to move, the sliding plate 41 moves through the gear groove 411 to drive the rotating gear 51 to rotate, the rotating gear 51 drives the bearing frame 2 to rotate through the intermediate piece 52 and the bevel gear set 53, and further drives the hoop 02 to rotate, so as to control the folding of the hoop 02.

[0045] With reference to Figure 6 , Figure 7 , the intermediate piece 52 comprises a worm 521, a worm wheel 522 and an intermediate rod 523, the worm 521 is rotatably assembled in the connecting plate 3, the worm 521 is coaxially connected with the rotating gear 51, the worm wheel 522 is also rotatably assembled in the connecting plate 3, the intermediate rod 523 is coaxially arranged with the worm wheel 522, and the worm wheel 522 is engaged with the worm 521. The bevel gear set 53 comprises a bevel gear one 531 and a bevel gear two 532, the bevel gear one 531 is coaxially connected with the intermediate rod 523, the bevel gear two 532 is coaxially arranged with the rotating shaft of the bearing frame 2, and the bevel gear one 531 is engaged with the bevel gear two 532.

[0046] When the sliding plate 41 moves, the rotating gear 51 is driven to rotate through the gear groove 411, the worm 521 drives the worm wheel 522 to rotate, the worm wheel 522 drives the bevel gear one 531 to rotate through the intermediate rod 523, and the bevel gear one 531 drives the bearing frame 2 to rotate through the bevel gear two 532. Meanwhile, the worm wheel 522 and the worm 521 are self-locked, that is, when the worm 521 does not rotate, the worm wheel 522 will not drive the worm 521 to rotate, so as to fix the position of the bearing frame 2. After the hoop 02 is fixed on the pier 01, the hoop 02 is separated from the bearing frame 2, then the bearing frame 2 is lifted upward and separated from the pier 01, and then the sliding plate 41 is pulled in the reverse direction, so as to drive the bearing frame 2 to rotate again to the unfolded state, so as to be hoisted next time.

[0047] With reference to Figure 6 , Figure 7 , the bevel gear set 53 is provided with two groups corresponding to the two groups of bearing frames 2, the intermediate rod 523 is located between the two groups of bevel gear sets 53, and the two ends of the intermediate rod 523 are connected with the bevel gear ones 531 in the two groups of bevel gear sets 53. When the intermediate rod 523 rotates, the two bevel gear ones 531 are driven to rotate, and further the two bearing frames 2 are driven to rotate, so as to drive the two hoops 02 to rotate synchronously.

[0048] With reference to Figure 8 , Figure 9 , Figure 10 , Figure 11The installation groove 21 and the through groove 22 are arranged on the receiving frame 2, the through groove 22 is located below the receiving frame 2 and communicates with the installation groove 21, that is, the through groove 22 is located on the side of the receiving frame 2 close to the hoop 02. The connecting block 6 is arranged in the installation groove 21, the connecting block 6 is slidingly assembled in the installation groove 21, the end of the connecting rope 03 away from the hoop 02 passes through the through groove 22 and is connected with the connecting block 6, and the installation groove 21 comprises an inclined portion 211, and the end of the inclined portion 211 close to the pier 01 is arranged in a downward inclined manner. The lower side of the connecting block 6 is provided with a slope, the slope of the connecting block 6 is matched with the inclined portion 211, and the connecting block 6 slidingly abuts with the inclined portion 211 through the slope. The control assembly 7 is arranged on the receiving frame 2, and the control assembly 7 is used for limiting the position of the connecting block 6.

[0049] In the closing stage of the hoop 02 installation operation, in order to fundamentally avoid the direct hard collision and scraping damage between the hoop 02 body and the side surface of the pier 01, and prevent the hoop 02 from being deformed or the surface of the pier 01 from being damaged due to the collision, a reasonable size safety gap needs to be reserved in advance between the inner side of the hoop 02 and the outer surface of the pier 01. After the receiving frame 2 drives the two hoop 02 halves to complete the preliminary closing positioning, the control assembly 7 arranged on the receiving frame 2 releases the mechanical limiting constraint of the connecting block 6, under the synergistic action of the self-gravitational potential energy of the hoop 02 and the guide structure of the inclined portion 211, the connecting block 6 will slide downward along the inclined direction of the inclined portion 211, and in the sliding process, the connecting block 6 drives the two hoop 02 halves to realize the horizontal closing to the side of the pier 01 through the connecting rope 03, thereby driving the hoop 02 body to gradually fit the outer surface of the pier 01, and finally aligning the end portions of the two hoop 02 halves.

[0050] After the end portions of the two hoop 02 halves are aligned, the operator performs the pre-fixing operation on the butt joint of the hoop 02 through the high-strength bolt and nut assembly, and preliminarily limits the displacement of the hoop 02. In addition, when the connecting block 6 slides to the bottom of the inclined portion 211 and stops sliding, a preset fine adjustment gap still needs to be reserved between the inner side of the hoop 02 and the outer surface of the pier 01. The design purpose of the fine adjustment gap is to provide adjustment space for subsequent fixing operation, so that the operator can finely calibrate the installation precision parameters such as the levelness, coaxiality and perpendicularity of the hoop 02 by adjusting the tightness of the bolt and nut, and finally stably, accurately and reliably fix the two hoop 02 halves to the specified installation position of the pier 01 through the fastening operation of the bolt and nut, so as to ensure that the overall stability and bearing capacity of the hoop 02 installation meet the design requirements.

[0051] Referring to Figure 8 , Figure 9 , Figure 10 , Figure 11The control assembly 7 comprises a stopper 71, a control plate 72, a rotating plate 73 and a control rope 74. The stopper 71 is slidably arranged in the mounting groove 21. The control plate 72 is arranged at one end of the receiving frame 2 away from the connecting plate 3 and is slidably arranged on the receiving frame 2. The rotating plate 73 is rotatably arranged in the receiving frame 2. One end of the control plate 72 is located outside the receiving frame 2 and the other end extends into the receiving frame 2 and abuts against the rotating plate 73. One end of the control rope 74 is connected to the upper portion of the stopper 71 and the other end is connected to the rotating plate 73. The control rope 74 is connected to the end of the rotating plate 73 away from the control plate 72. The control plate 72 and the control rope 74 are located on the two sides of the rotating plate 73, respectively.

[0052] Initially, the connecting block 6 abuts against the stopper 71 near the side of the other receiving frame 2. At this time, the stopper 71 limits the position of the abutting block. When the receiving frames 2 are folded, the end portions of the two receiving frames 2 abut against each other and push the control plate 72 to move towards the inside of the receiving frame 2. The control plate 72 pushes the rotating plate 73 to rotate when moving. The rotating plate 73 pulls the control rope 74 when rotating. The control rope 74 drives the stopper 71 connected thereto to move stably in the vertical direction upwards under the action of the traction force. In this process, the stopper 71 gradually moves away from the abutting state with the connecting block 6 until the limiting constraint on the connecting block 6 is completely released. After the limiting constraint is released, the connecting block 6 slides along the preset slope surface of the inclined portion 211 under the guidance of the inclined portion 211 and the synergistic action of the self-gravity of the hoop 02, thereby driving the hoop 02 to gradually approach the pier 01 in the horizontal direction.

[0053] Referring to Figure 8 , Figure 9 Elastic members one 8 and two 9 are arranged in the mounting groove 21. The elastic members one 8 and two 9 are both springs. The two ends of the elastic member one 8 are connected to the connecting block 6 and the inner wall of the mounting groove 21, respectively. The elastic member one 8 is located at the side of the connecting block 6 away from the pier 01 and is used to drive the connecting block 6 to move in the direction away from the pier 01. The elastic member two 9 is sleeved outside the control rope 74. The two ends of the elastic member two 9 are connected to the inner wall of the mounting groove 21 and the stopper 71, respectively. The elastic member two 9 is arranged in the vertical direction. The elastic member two 9 is used to drive the stopper 71 to move downwards.

[0054] When the connecting rope 03 is not connected with the hoop 02, the elastic member one 8 drives the connecting block 6 to move away from the other receiving frame 2, and drives the connecting block 6 to pass through the stop block 71 and move to the side away from the other receiving frame 2, and at the same time, the elastic member two 9 drives the stop block 71 to be located on the moving track of the connecting block 6. When the connecting rope 03 is connected with the hoop 02 and hoists the hoop 02, under the action of the gravity of the hoop 02, the connecting block 6 is driven to slide downwards to abut against the side surface of the stop block 71, and the stop block 71 limits the connecting block 6. After the hooping 02 is hoisted and fixed, the connecting rope 03 is separated from the hoop 02, and the elastic member one 8 can drive the connecting block 6 to move to the initial position again, so as to hoist the hoop 02 again.

[0055] A guide inclined surface is arranged below the stop block 71, and the guide inclined surface is arranged towards the bottom of the inclined part 211, so that when the elastic member one 8 drives the connecting block 6 to move upwards, the connecting block 6 can abut against the guide inclined surface of the stop block 71, so that the connecting block 6 can pass through the stop block 71 through the guide inclined surface, and the phenomenon that the stop block 71 interferes with the resetting of the connecting block 6 is avoided.

[0056] Referring to Figure 11 Two groups of stop blocks 71, connecting blocks 6 and connecting ropes 03 are arranged on each receiving frame 2, two groups of connecting ropes 03 are connected with different positions on the hoop 02 respectively, and the sliding directions of the two connecting blocks 6 on the receiving frame 2 are parallel to each other. The control rope 74 includes a connecting end one 741 and a connecting end two 742, wherein the connecting end one 741 and the connecting end two 742 are located at the end of the control rope 74 away from the rotating plate 73, and the connecting end one 741 and the connecting end two 742 are connected with the two groups of stop blocks 71 respectively.

[0057] When the rotating plate 73 rotates to pull the control rope 74, the control rope 74 simultaneously pulls the two groups of stop blocks 71 to move through the connecting end one 741 and the connecting end two 742, thereby simultaneously releasing the restriction on the two groups of connecting blocks 6 on the receiving frame 2, and when the receiving frame 2 abuts, the connecting block 6 drives the two hoops 02 to approach the pier 01 synchronously.

[0058] The implementation principle of the present application is that: in the initial state, two groups of symmetrically arranged receiving frames 2 are in a preset angle opening state and are fixed. During hoisting operation, the hoisting device is connected with the lifting lug 31 on the top of the receiving frame 2 through the lifting rope 1 to realize overall hoisting, and the receiving frame 2 is connected with the hoop 02 through the connecting rope 03. Since the receiving frame 2 is in an open state, and the opening amplitude is greater than the maximum size of the cross section of the pier 01, an operation space is reserved for subsequent sleeving operation.

[0059] When the connecting plate 3 is lifted to a preset height by the lifting action, the connecting plate 3 is driven to move to the pier 01 direction by the horizontal displacement operation of the lifting equipment, and then the two groups of hoops 02 are synchronously driven to move along the side of the pier 01 by the receiving frame 2. When the hoops 02 are completely moved to the preset sleeving area outside the pier 01, the push plate 42 on the side of the receiving frame 2 close to the pier 01 abuts against the outer wall of the pier 01, and the push plate 42 drives the sliding plate 41 to move under the reaction force of the pier 01. The movement of the sliding plate 41 drives the rotating gear 51 to rotate through the tooth groove 411 on the side of the sliding plate 41, the rotating gear 51 transmits power through the coaxially connected worm 521, the worm 521 and the worm wheel 522 are engaged to realize the conversion of the movement direction, and the worm wheel 522 transmits the torque to the rotating shaft of the receiving frame 2 through the bevel gear set 53, and finally drives the two groups of receiving frames 2 to synchronously rotate to the pier 01 direction around the rotating shaft.

[0060] When the receiving frame 2 reaches the completely closed state, the free ends of the two groups of receiving frames 2 away from the connecting plate 3 abut against each other, and at this time the center lines of the two hoops 02 coincide with the center axis of the pier 01. At the same time of the abutment of the end of the receiving frame 2, the control plates 72 arranged at the corresponding positions of the two groups of receiving frames 2 are extruded and synchronously pushed into the interior of the receiving frame 2, the movement of the control plate 72 drives the rotating plate 73 to rotate, the other end of the rotating plate 73 pulls the control rope 74, and the control rope 74 drives the stop block 71 to move upward in the vertical direction. When the stop block 71 is separated from the connecting block 6, the locking restriction on the connecting block 6 is released, the connecting block 6 slides downward along the inclined part 211 under the action of the inclined part 211, the connecting block 6 drives the hoop 02 to further approach the pier 01 through the connecting rope 03, and finally the abutting ends of the two hoops 02 are aligned to form a complete ring-shaped holding structure, which provides a stable assembly reference for subsequent fixing and installation by fastening members such as bolts. The present application can avoid interference with the pier 01 by maintaining the hoops 02 in an open state in the initial hoisting stage, ensure that the hoops 02 can be smoothly moved to the sleeving position through the side of the pier 01, and improve the hoisting efficiency and hoisting accuracy of the hoops 02.
