[0002] With the rapid pace of social development in my country, the utilization rate of underground space in modern building construction is increasing, especially in the construction of underground transportation facilities such as urban rail transit, which requires the use of deep foundation pit support structures for diaphragm walls. Diaphragm wall reinforcement cages are an indispensable part of diaphragm wall engineering, and require cranes to lift them to designated positions. A crane is a type of lifting machinery widely used in ports, workshops, power plants, construction sites, and other similar locations for lifting and handling.

[0003] Currently, a Chinese patent application with application number CN201210550120.X discloses an integral hoisting device and method for ultra-long steel cages of underground continuous walls, including a main hoisting device and an auxiliary hoisting device. The main hoisting device includes a main hook, a main spreader beam, a main pulley, a main hoisting rope, a first hoisting point, a second hoisting point, and a third hoisting point. The main hook is connected to the main spreader beam, the main pulley is installed on the main spreader beam, one end of the main hoisting rope is fixed to the first hoisting point, and the other end passes through the main pulley and the second hoisting point and is fixed to the third hoisting point. The first hoisting point is located on the steel cage. On the soil-facing surface of the top of the reinforcing cage, the second lifting point is located on the pit-facing surface of the middle section of the reinforcing cage, and the third lifting point is located on the pit-facing surface of the top of the reinforcing cage; the auxiliary lifting device includes an auxiliary hook, an auxiliary spreader beam, an auxiliary pulley, an auxiliary lifting rope, a fourth lifting point, and a fifth lifting point.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] A type of hoisting equipment for lifting and hoisting steel cages for underground continuous walls, such as Figure 1It includes several mounting blocks 1, which are arranged from left to right. Adjacent mounting blocks 1 are connected by connectors. At this time, each mounting block 1 forms a spreader beam. The bottom end of the spreader beam is connected to several sliding plates 2 by sliding members. The bottom end of each sliding plate 2 is provided with a pulley 3. The mounting blocks 1 located at the leftmost and rightmost ends are provided with lifting rings 4.

[0023] like Figure 1 When the length of the carrying pole beam needs to be adjusted, simply remove one of the mounting blocks 1 with the lifting ring 4 using the connector, and then increase or decrease the number of mounting blocks 1 forming the carrying pole beam using the connector to adjust the length of the carrying pole beam. When the position of the pulley 3 on the carrying pole beam needs to be adjusted, simply slide the sliding plate 2 horizontally on the carrying pole beam using the sliding component to adjust the position of the pulley 3 on the carrying pole beam. This improves the applicability of the carrying pole beam and pulley 3 and makes it simple and convenient to use.

[0024] The two lifting rings 4 can be connected to an external crane via connecting ropes, and the pulley 3 can be the main pulley or auxiliary pulley in the overall hoisting device and method for ultra-long steel cages of underground continuous wall with application number CN201210550120.X.

[0025] like Figure 1 and Figure 2 The connector includes an insert 5 located on the right side of the mounting block 1 and a slot 6 located on the left side of the mounting block 1 for horizontal insertion of the insert 5. The insert 5 on one of two adjacent mounting blocks 1 is horizontally inserted into the slot 6 on the other mounting block 1. Threaded grooves 7 are provided on opposite sides of the insert 5. A connecting groove 8 that mates with the threaded groove 7 is provided on one end of the mounting block 1 near the slot 6. A first bolt 9 passes through the connecting groove 8, and one end of the first bolt 9 extends into the threaded groove 7 and is threadedly connected to the threaded groove 7. The purpose of this design is that when it is necessary to connect the two mounting blocks 1 together, it is only necessary to horizontally insert the insert 5 on one mounting block 1 into the slot 6 on the other mounting block 1. At this time, the threaded groove 7 on the insert 5 in the slot 6 corresponds to the connecting groove 8. Then, one end of the first bolt 9 is screwed into the threaded groove 7 through the connecting groove 8. At this time, the two mounting blocks 1 can be installed together, making assembly and disassembly simple.

[0026] like Figure 2 and Figure 3 and Figure 4The sliding component includes a sliding groove 10 at the bottom of the mounting plate, and the sliding groove 10 is connected to the left and right sides of the mounting plate. Two adjacent sliding grooves 10 are connected, and the sliding grooves 10 on each mounting plate form a total sliding groove. Each sliding plate 2 is horizontally slidably connected to the total sliding groove, and the bottom end of the sliding plate 2 extends vertically to the outside of the total sliding groove. A suspension plate 12 is horizontally provided on one side of the sliding plate 2 in the sliding groove 10, and a limiting member is provided on the suspension plate 12 to restrict the sliding of the sliding plate 2 in the total sliding groove. The purpose of this setting is that by pushing the sliding plate 2 to move horizontally in the total sliding groove, the position of the pulley 3 on the spreader beam can be adjusted. After the adjustment is completed, the sliding plate 2 is restricted by the limiting member so that it cannot slide.

[0027] When it is necessary to reduce the number of pulleys 3 on the carrying pole beam, simply slide the sliding plate 2 on the carrying pole beam horizontally out of the main sliding groove. This will reduce the number of pulleys 3 on the carrying pole beam. Similarly, when it is necessary to increase the number of pulleys 3 on the carrying pole beam, simply align the sliding plate 2 not installed on the carrying pole beam with the main sliding groove and slide it in. It is simple and convenient to use.

[0028] like Figure 3 The limiting component includes several slots 13 vertically located at the bottom of the main sliding groove, with each slot 13 spaced apart along the length of the main sliding groove. A second bolt 14 is threaded onto the suspension plate 12, with one end of the second bolt 14 passing through the suspension plate 12 and vertically inserted into one of the slots 13. The purpose of this arrangement is to restrict the slide plate 2 by cooperating with the second bolt 14 on the suspension plate 12 and one of the slots 13 at the bottom of the main sliding groove, preventing it from sliding within the main sliding groove. This design is simple and convenient to use.

[0029] like Figure 4 The top of the insert 5 is provided with a cleaning groove 15 that communicates with the bottom of the threaded groove 7. The purpose of this setting is that when two adjacent mounting blocks 1 are installed together by the cooperation of the insert 5, the slot 6, the threaded groove 7, the connecting groove 8, and the first bolt 9, an external air source is used to blow air into the cleaning groove 15. At this time, impurities or debris that have entered the threaded groove 7 when the mounting block 1 is idle can be blown out, reducing the occurrence of impurities or debris in the threaded groove 7 affecting the screwing of the first bolt 9 into the threaded groove 7. It is simple and convenient to use.
