Description

Technical Field

[0001] This invention belongs to the field of wharf construction technology, and in particular relates to a double-plate synchronous hoisting device for wharf construction. Background Technology

[0002] High-pile wharves are an important type of wharf structure. Their basic components mainly include the following parts: the superstructure, which covers the construction of pile caps, component installation and surface layer construction; and the substructure, which is mainly composed of pile foundations, used to support the superstructure, transfer the upper load to the foundation, and play a role in stabilizing the foundation and maintaining the stability of the bank slope.

[0003] Currently, the installation of cantilever slabs at the expansion joints of traditional high-pile wharves is carried out by installing them piece by piece using a dual-machine platform crane. This method has problems such as cross-operation, limited space, long construction period, low installation accuracy, and difficulties in installing the second slab and poor straightness of the line. These problems not only endanger the safety of construction personnel, but may also affect the overall stability of the wharf structure.

[0004] Therefore, there is an urgent need to design a double-plate synchronous hoisting equipment for wharf construction to solve the problems of poor construction quality and long construction period of cantilever slabs at expansion joints mentioned above. Summary of the Invention

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0040] The following is a reference to the appendix. Figure 1 To be continued Figure 11 This invention describes a double-plate synchronous hoisting device for wharf construction.

[0041] Currently, the installation of cantilever slabs at the expansion joints of traditional high-pile wharves is carried out by installing them piece by piece using a dual-machine platform crane. This has problems such as cross-operation, limited space, long construction period, low installation accuracy, and difficulties in installing the second slab and poor straightness of the line.

[0042] Therefore, the present invention provides a double-plate synchronous hoisting device for wharf construction, such as... Figure 1 and Figure 2 As shown, the structure includes a first transverse main rod 1 and a second transverse main rod 2. Two longitudinal main rods 3 connect the first transverse main rod 1 and the second transverse main rod 2, thus forming a frame structure. Four first lifting points 401 are provided on the first precast cantilever slab 4, and four second lifting points 501 are provided on the second cantilever slab. Lifting gaps 6 are provided on both the first transverse main rod 1 and the second transverse main rod 2 to accommodate the first lifting points 401 and the second lifting points 501. Lifting seats 7 are provided on both the first transverse main rod 1 and the second transverse main rod 2. One lifting seat 7 is connected to each first lifting point 401, and one lifting seat 7 is connected to each second lifting point 501, thereby enabling the frame structure to be synchronously connected to the first precast... The cantilever slab 4 and the second precast cantilever slab 5 are connected to hook points 8 on the first transverse main rod 1 and the second transverse main rod 2. The hook points 8 are for the lifting equipment to hook onto. Specifically, the first precast cantilever slab 4 and the second precast cantilever slab 5 are connected synchronously through the frame structure to form a whole slab. The width of the whole slab is greater than the width between two adjacent pile caps, so that the whole slab can be placed on the two pile caps. The two pile caps provide support for the whole slab. Then, the connection between the first precast cantilever slab 4 and the second precast cantilever slab 5 and the pile caps is poured. This fundamentally avoids the drawback of using a double-machine platform crane to install the cantilever slabs piece by piece at the expansion joint, thereby ensuring the construction quality and reducing the construction period.

[0043] As a preferred option, such as Figure 1 and Figure 2As shown, the first suspension point 401 includes a first embedded part 4011, a second embedded part 4012, a third embedded part 4013, and a fourth embedded part 4014 prefabricated on the first prefabricated cantilever slab 4. The straight line formed by connecting the first embedded part 4011 and the second embedded part 4012 is parallel to the straight line formed by connecting the third embedded part 4013 and the fourth embedded part 4014. The second suspension point 501 includes a fifth embedded part 5011, a sixth embedded part 5012, a seventh embedded part 5013, and an eighth embedded part 5014 prefabricated on the second prefabricated cantilever slab 5. The straight line formed by connecting the fifth embedded part 5011 and the sixth embedded part 5012 is parallel to the straight line formed by connecting the seventh embedded part 5013 and the eighth embedded part 5014. The first embedded part 4011... 11. The second embedded part 4012, the fifth embedded part 5011 and the sixth embedded part 5012 are located within the hoisting gap 6 of the first transverse main rod 1, and the third embedded part 4013, the fourth embedded part 4014, the seventh embedded part 5013 and the eighth embedded part 5014 are located within the hoisting gap 6 of the second transverse main rod 2. A hoisting seat 7 is connected to each of the first embedded part 4011, the second embedded part 4012, the third embedded part 4013, the fourth embedded part 4014, the fifth embedded part 5011, the sixth embedded part 5012, the seventh embedded part 5013 and the eighth embedded part 5014. The gap between the first transverse main rod 1 and the second transverse main rod 2 is adjusted by the hoisting seat 7. Specifically, the first precast cantilever slab 4 and the second precast cantilever slab 5 are rectangular slabs. The four embedded parts on the first precast cantilever slab 4 and the four embedded parts on the second precast cantilever slab 5 are evenly distributed at the corner positions. The four embedded parts on the first precast cantilever slab 4 are connected to four lifting seats 7, thereby being stably fixed to the frame structure through the lifting seats 7. The four embedded parts on the second precast cantilever slab 5 are connected to four lifting seats 7, thereby being stably fixed to the frame structure through the lifting seats 7. At the same time, the eight lifting seats 7 can be adjusted to drive the first precast cantilever slab 4 and the second precast cantilever slab 5 to move on the frame structure, thereby controlling the gap between the first precast cantilever slab 4 and the second precast cantilever slab 5, thus meeting the expansion joint requirements in the construction.

[0044] As a preferred option, such as Figure 2 and Figure 3As shown, a first slide rail 101 is fixedly connected to the first transverse main body 1, and a first left slide block 102 and a first right slide block 103 are slidably connected to the first slide rail 101. A lifting seat 7 connected to the second embedded part 4012 is fixedly connected to the first left slide block 102, and a lifting seat 7 connected to the fifth embedded part 5011 is fixedly connected to the first right slide block 103. A second slide rail 201 is fixedly connected to the second transverse main body 2, and a second left slide block 202 and a second right slide block 203 are slidably connected to the second slide rail 201. The lifting seat 7 connected to component 4014 is fixedly connected to the second left slide 202, and the lifting seat 7 connected to the seventh embedded component 5013 is fixedly connected to the second right slide 203. The embodiment of the present invention takes the adjustment of the first right slide 103 and the second right slide 203 as an example. The first transverse main rod 1 adjusts the position of the first right slide 103 on the first slide rail 101, and the second transverse main rod 2 adjusts the position of the second right slide 203 on the second slide rail 201, thereby controlling the gap between the first precast cantilever slab 4 and the second precast cantilever slab 5. Specifically, first, connect the lifting seats 7 on the first left slide block 102 and the second left slide block 202 to the first precast cantilever slab 4. Then, connect the lifting seats 7 on the first right slide block 103 and the second right slide block 203 to the second precast cantilever slab 5. Keep the first left slide block 102 and the second left slide block 202 stationary. Adjust the positions of the first right slide block 103 on the first slide rail 101 and the second right slide block 203 on the second slide rail 201 until the gap between the first precast cantilever slab 4 and the second precast cantilever slab 5 meets the expansion joint requirements. Finally, fix the lifting seats 7 connected to the first embedded part 4011 and the sixth embedded part 5012 on the first transverse main rod 1. Fix the lifting seats 7 connected to the third embedded part 4013 and the eighth embedded part 5014 on the second transverse main rod 2 to complete the fixing of the first precast cantilever slab 4 and the second precast cantilever slab 5.

[0045] As a preferred option, such as Figure 4 and Figure 5As shown, a first sleeve 104 is fixedly connected to the first left slide block 102, and a first adjusting block 105 is fixedly connected to the first right slide block 103. A first screw 106 is rotatably connected inside the first sleeve 104, and the first screw 106 is threadedly connected to the first adjusting block 105. Rotating the first screw 106 adjusts the distance between the first left slide block 102 and the first right slide block 103. A second sleeve 204 is fixedly connected to the second left slide block 202, and a second adjusting block 205 is fixedly connected to the second right slide block 203. A second screw 206 is rotatably connected inside the second sleeve 204, and the second screw 206 is threadedly connected to the second adjusting block 205. Rotating the second screw 206 adjusts the distance between the second left slide block 202 and the second right slide block 203. Specifically, the operator can precisely adjust the distance between the first precast cantilever slab 4 and the second precast cantilever slab 5 by rotating the first screw 106 and the second screw 206, achieving high adjustment accuracy.

[0046] As a preferred option, such as Figure 4 and Figure 5 As shown, both the first screw 106 and the second screw 206 have through holes. The operator can insert a round rod into the through hole, thereby rotating the round rod to make the first screw 106 and the second screw 206 rotate. Optionally, the first screw 106 and the second screw 206 can also be connected to a motor. The output end of the motor is fixedly connected to the ends of the first screw 106 and the second screw 206. The operator can control the forward and reverse rotation of the motor to realize the forward and reverse rotation of the first screw 106 and the second screw 206.

[0047] As a preferred option, such as Figure 6As shown, the lifting base 7 includes a lifting base 701, which is used to connect the first horizontal main body rod 1 or the second horizontal main body rod 2. The lifting base 701 is provided with a receiving groove 702. A stop block 703 is connected to the top of the lifting base 701. A connecting rod 704 is connected to the stop block 703. After the connecting rod 704 is connected to the first lifting point 401 or the second lifting point 501, it passes through the receiving groove 702 and the stop block 703 in sequence and is screwed to the connecting nut 705. Specifically, the connecting rod 704 of the lifting base 7 is screwed to the connecting nut 705, thereby adjusting the distance between the four first lifting points 401 or the four second lifting points 501 and the lifting base 701 through the screwed structure of the connecting rod 704 and the connecting nut 705. At the same time, the level of the first precast cantilever slab 4 can be adjusted by the cooperation between the connecting rod 704 and the connecting nut 705 on the four lifting bases 7 connected to the first precast cantilever slab 4. The level of the second precast cantilever slab 5 can also be adjusted by the cooperation between the connecting rod 704 and the connecting nut 705 on the four lifting bases 7 connected to the second precast cantilever slab 5. At the same time, the flatness between the first precast cantilever slab 4 and the second precast cantilever slab 5 can also be adjusted, so that the first precast cantilever slab 4 and the second precast cantilever slab 5 are on the same horizontal plane.

[0048] The matching method between the hoisting seat 7 and the first hoisting point 401 and the second hoisting point 501 is selected according to the construction requirements. If the first hoisting point 401 and the second hoisting point 501 are selected by pre-embedding U-shaped round steel, the connecting rod 704 of the hoisting seat 7 is connected to the U-shaped round steel through the lifting ring. If the first hoisting point 401 and the second hoisting point 501 are selected by pre-embedding threaded ends, the connecting rod 704 of the hoisting seat 7 is connected to the pre-embedding threaded end through a nut that matches the threaded end, thereby realizing detachable recycling.

[0049] In some embodiments, the distance between the first precast cantilever slab 4 and the second precast cantilever slab 5 can also be adjusted using the following structure:

[0050] like Figures 7-9As shown, the first transverse main body 1 includes a first left transverse bar 1001, a first right transverse bar 1002, and a first intermediate transverse bar 1003. The two ends of the first intermediate transverse bar 1003 are slidably connected to the first left transverse bar 1001 and the first right transverse bar 1002, respectively. A lifting seat 7 connected to the first embedded part 4011 and a lifting base 7 connected to the second embedded part 4012 are located on the first left transverse bar 1001. A lifting base 7 connected to the fifth embedded part 5011 and a lifting base 7 connected to the sixth embedded part... The lifting base 7 connected to 5012 is located on the first right crossbar 1002. A third sleeve 1004 is fixedly connected to the first left crossbar 1001. A third adjusting block 1005 is fixedly connected to the first right crossbar 1002. A third screw 1006 is rotatably connected inside the third sleeve 1004. The third screw 1006 is threadedly connected to the third adjusting block 1005. Rotating the third screw 1006 adjusts the distance between the first left crossbar 1001 and the first right crossbar 1002. The second transverse main body 2 includes a second left transverse bar 2001, a second right transverse bar 2002, and a second intermediate transverse bar 2003. The two ends of the second intermediate transverse bar 2003 are slidably connected to the second left transverse bar 2001 and the second right transverse bar 2002, respectively. A lifting seat 7 connected to the third embedded part 4013 and a lifting base 7 connected to the fourth embedded part 4014 are located on the second left transverse bar 2001. A lifting base 7 connected to the seventh embedded part 5013 and a lifting base 7 connected to the eighth embedded part 5014 are also located on the second left transverse bar 2001. The lifting seat 7 connected to 14 is located on the second right crossbar 2002. A fourth sleeve 2004 is fixedly connected to the second left crossbar 2001, and a fourth adjusting block 2005 is fixedly connected to the second right crossbar 2002. A fourth screw 2006 is rotatably connected inside the fourth sleeve 2004. The fourth screw 2006 is threadedly connected to the fourth adjusting block 2005. Rotating the fourth screw 2006 adjusts the distance between the second left crossbar 2001 and the second right crossbar 2002. One longitudinal main body rod 3 is connected between the first left crossbar 1001 and the second left crossbar 2001, and another longitudinal main body rod 3 is connected between the first right crossbar 1002 and the second right crossbar 2002. Furthermore, as... Figures 7-9 As shown, both the third screw 1006 and the fourth screw 2006 have through holes. The operator can insert a round rod into the through hole, thereby rotating the round rod to make the third screw 1006 and the fourth screw 2006 rotate. Optionally, the third screw 1006 and the fourth screw 2006 can also be connected to a motor. The output end of the motor is fixedly connected to the end of the third screw 1006 and the fourth screw 2006. The operator can control the forward and reverse rotation of the motor to realize the forward and reverse rotation of the third screw 1006 and the fourth screw 2006.

[0051] Preferably, to accommodate different sizes of the first precast cantilever slab 4 and the second precast cantilever slab 5, such as Figure 3As shown, the longitudinal main body 3 includes a first longitudinal rod 301 and a second longitudinal rod 302. The first longitudinal rod 301 and the second longitudinal rod 302 are slidably connected to each other, thereby adjusting the length of the longitudinal main body 3. The first longitudinal rod 301 is connected to the first transverse main body 1, and the second longitudinal rod 302 is connected to the second transverse main body 2.

[0052] Preferably, a fifth sleeve 303 is fixedly connected to the first longitudinal rod 301, and a fifth adjusting block 304 is fixedly connected to the second longitudinal rod 302. A fifth screw 305 is rotatably connected inside the fifth sleeve 303. The fifth screw 305 is threadedly connected to the fifth adjusting block 304. Rotating the fifth screw 305 adjusts the distance between the first longitudinal rod 301 and the second longitudinal rod 302. Optionally, the fifth screw 305 can be connected to a motor. The output end of the motor is fixedly connected to the end of the fifth screw 305. The operator controls the forward and reverse rotation of the motor to achieve the forward and reverse rotation of the fifth screw 305.

[0053] Furthermore, in order to further accommodate the errors that occur during the construction of the first precast cantilever slab 4 and the second precast cantilever slab 5, such as... Figures 1-3 As shown, the first longitudinal rod 301 is hinged to the first transverse main rod 1, and the second longitudinal rod 302 is hinged to the second transverse main rod 2. An angle locking member 9 is provided between the first longitudinal rod 301 and the first transverse main rod 1 to fix the frame structure. Specifically, this device can also be adapted when errors occur during the processing of the first suspension point 401 embedded in the first precast cantilever slab 4 or the second suspension point 501 embedded in the second precast cantilever slab 5. Here, we take the error during the processing of the fifth embedded part 5011 and the sixth embedded part 5012 on the second suspension point 501 as an example. At this time, the first embedded part 4011 and the second embedded part 4012 of the first suspension point 401 are not on the same straight line as the fifth embedded part 5011 and the sixth embedded part 5012 of the second suspension point 501, which leads to the first After the hoisting gap 6 of the transverse main rod 1 accommodates the first embedded part 4011, the second embedded part 4012, the fifth embedded part 5011 and the sixth embedded part 5012, the first transverse main rod 1 tilts and the first transverse main rod 1 is not parallel to the second transverse main rod 2. At this time, the lengths of the two longitudinal main rods 3 are adjusted to match the tilted first transverse main rod 1. At the same time, the angle between the first longitudinal rod 301 and the first transverse main rod 1 is locked by the angle locking part 9 to complete the fixation of the frame structure to accommodate the processing error.

[0054] As a further preferred embodiment, to increase the stability of the frame structure, the two longitudinal main rods 3 are arranged in opposite directions. If the first longitudinal rod 301 of one longitudinal main rod 3 is hinged to the first transverse main rod 1 and the second longitudinal rod 302 is hinged to the second transverse main rod 2, and the angle locking member 9 is located at the hinge position between the first longitudinal rod 301 and the first transverse main rod 1 of the longitudinal main rod 3, then the first longitudinal rod 301 of the other longitudinal main rod 3 is hinged to the second transverse main rod 2 and the second longitudinal rod 302 is hinged to the first transverse main rod 1, and the angle locking member 9 is located at the hinge position between the first longitudinal rod 301 and the second transverse main rod 2 of the longitudinal main rod 3. Thus, the two angle locking members 9 are arranged diagonally to ensure the stability of the frame structure.

[0055] As a preferred option, such as Figure 10 and Figure 11 As shown, the angle locking component 9 includes an ear plate 901 fixedly connected to the first transverse main body rod 1. A gear end 902, fixedly connected to the end of the first longitudinal rod 301, is rotatably connected within the ear plate 901. A locking seat 903 is threaded onto the ear plate 901, and a wedge-shaped locking block 904 is fixedly connected to the locking seat 903. The wedge-shaped locking block 904 matches the gear end 902. When the locking seat 903 is tightened, the wedge-shaped locking block 904 engages with the gear end 902 to lock the angle between the first transverse main body rod 1 and the first longitudinal rod 301. Specifically, after the frame structure is adjusted, the operator inserts the wedge-shaped locking block 904 into the gap between the gear end 902 and bolts the locking seat 903 onto the ear plate 901 to complete the locking.

[0056] This invention pre-assembles the first precast cantilever slab 4 and the second precast cantilever slab 5 according to the requirements of the structural section expansion joint. The spacing and height between the first precast cantilever slab 4 and the second precast cantilever slab 5 are adjusted by the hoisting seat 7. The installation accuracy is high, which can meet the construction requirements under various complex environmental conditions, avoid crane operations, eliminate the risk of cross-operations, reduce the safety risks of construction personnel, promote the promotion and innovation of safety standards in the construction industry, improve the overall convenience of cantilever slab construction, reduce the construction cycle of cantilever slabs and reduce construction risks through overall installation.
