Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and in particular, to a digital model assembled self-adjusting sling. Background Art

[0002] In the scenarios of engineering and hoisting operations, the requirements for hoisting in the industry development have reached a new height. On the one hand, various large-scale infrastructure construction and industrial equipment installation projects have emerged like mushrooms after a spring rain. The structures involved are becoming more and more diverse in shape, size, weight, and sling point layout. Taking the hoisting of large steel structures in bridge construction as an example, its length can reach dozens of meters, and the sling point spacing is irregular. The single fixed structure mode of traditional slings simply cannot match it. This not only makes it extremely easy for the structure to be out of balance and swing during the hoisting process, threatening the safety of on-site personnel and equipment, but also in the docking and installation link, due to the inability of the sling to be flexibly adjusted, a large number of auxiliary tools often need to be used and a lot of manpower is consumed to repeatedly calibrate, seriously delaying the project progress. Summary of the Invention

[0003] The present invention discloses a digital model assembled self-adjusting sling to solve the technical problem of complex and time-consuming adjustment of the sling during the hoisting process in the related art.

[0004] To solve the above problems, the present invention adopts the following technical solutions: The digital model assembled self-adjusting sling provided by some embodiments of the present application includes: a main load-bearing beam, a secondary load-bearing beam, a first sliding frame, a first driving member, and a locking structure. The secondary load-bearing beam is movably connected to the main load-bearing beam through the first sliding frame. The locking structure is arranged on the first sliding frame. The first driving member is arranged on the main load-bearing beam, and the first driving member is respectively connected to the first sliding frame and the locking structure arranged on the first sliding frame. The first driving member can drive the locking structure to switch between a locked state and an unlocked state, and when the locking structure is in the unlocked state, the first driving member can drive the first sliding frame to slide along the extending direction of the main load-bearing beam. When the locking structure is in the locked state, the locking structure is in limit cooperation with the main load-bearing beam and restricts the first sliding frame from sliding relative to the main load-bearing beam. When the locking structure is in the unlocked state, the locking structure is released from the limit cooperation with the main load-bearing beam.

[0005] The technical solutions adopted by the present invention can achieve the following beneficial effects: In the digital-analog assembled self-adjusting sling provided by the present application, the first driving member can not only be used to drive the secondary load-bearing beam to move along the extension direction of the main load-bearing beam and adjust the distance between the secondary load-bearing beams to adapt to the suspension points with different distances. In addition, the first driving member can also be used to drive the locking structure to lock the first carriage and the main load-bearing beam to prevent the first carriage from moving relative to the main load-bearing beam. In addition, during the lifting process, the first carriage and the main load-bearing beam are mainly limited by the locking structure, so that the force received during the lifting process can be prevented from being transferred to the first driving member, thereby protecting the first driving member. This solution is beneficial to simplifying the operation of adjusting the relative positions of the main load-bearing beam and the secondary load-bearing beam, beneficial to saving the time for adjusting the suspension point position when the crane hoists heavy objects, and improving the efficiency.

Detailed Description of the Embodiments

[0009] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative effort fall within the scope of protection of the present invention.

[0010] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0011] The following combines the attached Figures 1 to 13 drawings to describe in detail the digital model prefabricated self-adjusting sling provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0012] The present application provides a digital-analog assembled self-adjusting sling. This sling can be used for hoisting by a crane. Specifically, this sling can be used for, but is not limited to, hoisting large steel structures in bridge construction.

[0013] Referring to Figure 1 , the digital-analog assembled self-adjusting sling includes a main load-bearing beam 100, a secondary load-bearing beam 200, a first carriage 300, a first driving member 400, and a locking structure 500. Among them, the main load-bearing beam 100 is a basic structural member that can directly bear the main weight of the hoisted object and transfer the load to the main structure of the crane through connection with the crane hook. The secondary load-bearing beam 200 can assist the main load-bearing beam 100 in dispersing the load through multi-point support or adjustable connection methods.

[0014] Referring to Figure 1 and Figure 2 , the secondary load-bearing beam 200 is movably connected to the main load-bearing beam 100 through the first carriage 300. Referring to Figure 3 and Figure 4 , the locking structure 500 is arranged on the first carriage 300. The first driving member 400 is arranged on the main load-bearing beam 100, and the first driving member 400 is respectively connected to the first carriage 300 and the locking structure 500 arranged on the first carriage 300. Exemplarily, the first driving member 400 can drive the first carriage 300 to slide along the extension direction of the main load-bearing beam 100, and the first driving member 400 can drive the locking structure 500 to switch between a locked state and an unlocked state. In some embodiments, the extension direction of the main load-bearing beam 100 is the length direction of the main load-bearing beam 100. In some embodiments, the first carriage 300 can be provided with a roller structure to facilitate the sliding of the first carriage 300 along the main load-bearing beam 100. Exemplarily, the first driving member 400 can drive the locking structure 500 to switch between a locked state and an unlocked state. And in the case of the unlocked state of the locking structure 500, the first driving member 400 can drive the first carriage 300 to slide along the extension direction of the main load-bearing beam 100.

[0015] Referring to Figure 6 and Figure 7 , in the case of the locking structure 500 being in the locked state, the locking structure 500 is in limit cooperation with the main load-bearing beam 100 and restricts the relative sliding of the first carriage 300 with respect to the main load-bearing beam 100. Exemplarily, the locking structure 500 can be in limit cooperation with the main load-bearing beam 100 in the extension direction of the main load-bearing beam 100.

[0016] Referring to Figure 9 , in the case of the locking structure 500 being in the unlocked state, the locking structure 500 releases the limit cooperation with the main load-bearing beam 100.

[0017] The digital-analog assembled self-adjusting sling provided by the present application can replace manual adjustment of the position of the secondary load-bearing beam 200 through the first driving member 400 to achieve self-adjustment. In addition, after adjusting the position of the secondary load-bearing beam 200, the first driving member 400 can also realize the limiting cooperation between the first carriage 300 and the main load-bearing beam 100 through the first driving member 400, so as to lock the first carriage 300 to prevent the first carriage 300 and the secondary load-bearing beam 200 connected to the first carriage 300 from sliding relative to the main load-bearing beam 100, thereby ensuring the reliability during the hoisting process.

[0018] Referring to Figure 3 and Figure 4 , the locking structure 500 includes a limiting tongue 510 and a linkage rod 520. Among them, the limiting tongue 510 is used for limiting cooperation with the main load-bearing beam 100. The linkage rod 520 is used to connect the limiting tongue 510 and the first driving member 400, so that the first driving member 400 can drive the limiting tongue 510 to switch the locking structure 500 between the locked state and the unlocked state with the main load-bearing beam 100.

[0019] Referring to Figure 4 , Figure 6 and Figure 9 , the limiting tongue 510 is slidably arranged on the first carriage 300. Exemplarily, the first carriage 300 can be provided with a chute to guide the movement of the limiting tongue 510 relative to the first carriage 300. In some embodiments, the first carriage 300 can also be provided with a guide rail, so that the limiting tongue 510 can be slidably mated with the first carriage 300 through the guide rail. In some alternative embodiments, the direction in which the limiting tongue 510 can move relative to the first carriage 300 is perpendicular to, intersects with, or is skew to the extending direction of the main load-bearing beam 100.

[0020] Referring to Figure 5 and Figure 8 , in some embodiments, the linkage rod 520 is slidably arranged on the first carriage 300 along the extending direction of the main load-bearing beam 100. The linkage rod 520 is respectively connected to the first driving member 400 and the limiting tongue 510. Specifically, the linkage rod 520 can drive the limiting tongue 510 to be in limiting cooperation or release the limiting cooperation with the main load-bearing beam 100. When the limiting tongue 510 is in limiting cooperation with the main load-bearing beam 100, the linkage rod 520 is in abutting cooperation with the first carriage 300, and the linkage rod 520 can push the first carriage 300 to move along the first extending direction or the second extending direction of the main load-bearing beam 100, and the first extending direction is opposite to the second extending direction.

[0021] In the above embodiments, the linkage rod 520 can move relative to the first carriage 300 within a preset range. And when moving to the upper limit or the lower limit of the preset range, the linkage rod 520 can be in abutting cooperation with the first carriage 300.

[0022] Exemplarily, when the locking structure 500 is in the locked state, the linkage rod 520 is located at an intermediate position within a preset range where it is movable relative to the first carriage 300. During the process of adjusting the secondary load-bearing beam 200, the first driving member 400 can be used to drive the linkage rod 520 to move towards the upper limit position or the lower limit position of the preset range, so as to drive the limiting tongue 510 to move without the first carriage 300 moving relative to the main load-bearing beam 100, realizing the switching of the locking structure 500 from the locked state to the unlocked state. When the locking structure 500 is switched to the unlocked state, the first driving member 400 can continue to drive the linkage rod 520 to be in a stop and fit state with the first carriage 300 at the upper limit position or the lower limit position of the preset range. Therefore, during the process of the first driving member 400 further driving the linkage rod 520 in the original direction, the first carriage 300 will be driven to move, thereby adjusting the position of the first carriage 300.

[0023] In some embodiments, after the first carriage 300 moves to a preset position, the first driving member 400 is controlled to drive the linkage rod 520 to move in the opposite direction, so that the linkage rod 520 can drive the limiting tongue 510 to move, realizing the switching of the locking structure 500 from the unlocked state to the locked state.

[0024] Referring to Figure 5 and Figure 8 The linkage rod 520 is slidably arranged along the extending direction of the main load-bearing beam 100, and the linkage rod 520 can move between a third position, a fourth position and a fifth position. Exemplarily, one of the fourth position and the fifth position is the upper limit position where the linkage rod 520 moves relative to the first carriage 300 mentioned in the foregoing embodiment, and the other is the lower limit position where the linkage rod 520 moves relative to the first carriage 300 mentioned in the foregoing embodiment. The third position is a certain position between the fourth position and the fifth position. Preferably, the third position is the intermediate position between the fourth position and the fifth position, that is, the intermediate position within the moving range of the linkage rod 520 relative to the first carriage 300.

[0025] Exemplarily, referring to Figure 5 , when the linkage rod 520 is in the third position, the linkage rod 520 is disengaged from the stop and fit with the main load-bearing beam 100. Referring to Figure 8 , when the linkage rod 520 is in the fourth position, the linkage rod 520 is in stop and fit with the main load-bearing beam 100 and can push the first carriage 300 to move along the first extending direction of the main load-bearing beam 100. In some alternative embodiments, the linkage rod 520 is provided with a limiting structure, and the specific limiting structure can be, but is not limited to, a limiting protrusion. Specifically, referring to Figure 5 and Figure 8, the limiting structure can respectively abut and limit with the structure provided on the first carriage 300 for sliding cooperation with the linkage rod 520. In some embodiments, a guiding groove 521 can be provided on the limiting structure where the linkage rod 520 is used for limiting cooperation with the first carriage 300, and at least a part of the limiting tongue 510 is located in the guiding groove 521, so as to push against the limiting tongue 510 through the groove wall of the guiding groove 521 to realize the movement of the limiting tongue 510 relative to the first carriage 300.

[0026] In some embodiments, along the extending direction of the main load-bearing beam 100, the guiding groove 521 includes a first section, a second section and a third section which are connected in sequence. The groove widths of the first section and the third section are both smaller than that of the second section. And the first section, the second section and the third section are smoothly connected in sequence. Specifically, the limiting tongue 510 has a cylindrical protrusion, and the limiting tongue 510 is located in the guiding groove 521 through the cylindrical protrusion and abuts against the groove wall of the guiding groove 521. In some embodiments, the cylindrical protrusion can be kept in abutment with the groove wall of the guiding groove 521 through an elastic member.

[0027] In some embodiments, the groove width of the guiding groove 521 can also be set to be the same, and by setting the shape of the guiding groove 521, the cylindrical protrusion can slide relative to the first carriage 300 under the constraint of the guiding groove 521.

[0028] In some embodiments, when the linkage rod 520 is in the fifth position, the linkage rod 520 abuts and cooperates with the main load-bearing beam 100 and can push the first carriage 300 to move along the second extending direction of the main load-bearing beam 100. The first extending direction is opposite to the second extending direction.

[0029] In some embodiments, such as Figure 4 、 Figure 6 and Figure 9 shown, the locking structure 500 includes a first elastic member 530 and two limiting tongues 510. The first elastic member 530 is respectively connected to the two limiting tongues 510, and the first elastic member 530 can push the two limiting tongues 510 to switch from being released from the limiting cooperation with the main load-bearing beam 100 to being in the limiting cooperation with the main load-bearing beam 100. Exemplarily, referring to Figure 5 and Figure 6 , the first elastic member 530 is arranged between the two limiting tongues 510 so that the first elastic member 530 can push the two limiting tongues 510 away from each other, so that the two limiting tongues 510 can be in the limiting cooperation with the opposite sides of the main load-bearing beam 100 under the action of the first elastic member 530.

[0030] In some embodiments, the main load-bearing beam 100 is provided with a plurality of limiting grooves 111. The plurality of limiting grooves 111 are arranged at intervals along the extending direction of the main load-bearing beam 100, so that the limiting tongue 510 can be in limiting cooperation with the main load-bearing beam 100 at different positions in the extending direction of the main load-bearing beam 100. In some embodiments, racks 110 are arranged on both sides of the main load-bearing beam 100 in the height direction. Limiting grooves 111 are formed between two adjacent teeth in the racks 110.

[0031] Referring to Figure 6 , when the limiting tongue 510 is in limiting cooperation with the main load-bearing beam 100, at least part of the limiting tongue 510 is embedded in the limiting groove 111. Exemplarily, the end of the limiting tongue 510 has a protrusion adapted to the limiting groove 111, so that the limiting tongue 510 can be at least partially inserted into the limiting groove 111. Referring to Figure 9 , when the limiting tongue 510 is disengaged from the limiting cooperation with the main load-bearing beam 100, the limiting tongue 510 moves out of the limiting groove 111.

[0032] In some embodiments, referring to Figure 4 , the linkage rod 520 has a guiding groove 521, and at least part of the limiting tongue 510 is arranged in the guiding groove 521. Specifically, in some embodiments, in order to facilitate the setting of the guiding groove 521, the linkage rod 520 can be widened at the position where the guiding groove 521 is set, so that the linkage rod 520 can set the guiding groove 521. Further optionally, the widened part of the linkage rod 520 can be used for limiting cooperation with the first carriage 300 by abutting. During the sliding of the linkage rod 520 relative to the main load-bearing beam 100, the linkage rod 520 drives the limiting tongue 510 to slide relative to the first carriage 300 through the guiding groove 521.

[0033] Referring to Figure 5 and Figure 8 , the digital model assembly type self-adjusting sling in some embodiments further includes two limiting members 310 and two second elastic members 320 arranged on the first carriage 300. The two limiting members 310 and the two second elastic members 320 are both arranged at intervals along the extending direction of the main load-bearing beam 100 and symmetrically on both sides of the locking structure 500 opposite to each other. The limiting members 310 are movably arranged on the first carriage 300, and the limiting members 310 can be in limiting cooperation or disengaged from the limiting cooperation with the linkage rod 520. The second elastic members 320 are respectively connected to the first carriage 300 and the limiting members 310. During the process of the linkage rod 520 driving the limiting tongue 510 to switch from being disengaged from the limiting cooperation with the main load-bearing beam 100 to being in limiting cooperation with the main load-bearing beam 100, the linkage rod 520 can drive the limiting members 310 to move towards the direction close to the locking structure 500, and drive the first carriage 300 to slide relative to the main load-bearing beam 100 through the second elastic members 320.

[0034] Specifically, in the above embodiments, when the limiting tongue 510 is not aligned with the limiting groove 111, the first driving member 400 can push the first carriage 300 to move along the main load-bearing beam 100 under the elastic force of the second elastic member 320. When the limiting tongue 510 is aligned with the limiting groove 111, the limiting tongue 510 can be at least partially embedded in the limiting groove 111 under the action of the first elastic member 530, so that the first carriage 300 is in limiting cooperation with the main load-bearing beam 100.

[0035] In some alternative embodiments, when the limiting tongue 510 is in limiting cooperation with the main load-bearing beam 100, the linkage rod 520 can drive the limiting member 310 to slide relative to the first carriage 300, resulting in the limiting member 310 being disengaged from the limiting cooperation with the linkage rod 520.

[0036] Referring to Figure 8 and Figure 5 , the first carriage 300 further includes a first trigger member 330. The first trigger member 330 is disposed on the path of the limiting member 310 moving towards the locking structure 500. The first trigger member 330 has a first guiding surface 331, and the first guiding surface 331 is inclined. Specifically, the first guiding surface 331 is inclined relative to the extending direction of the linkage rod 520, such as the moving direction of the linkage rod 520 relative to the first carriage 300 or the length direction of the linkage rod 520. During the process of the limiting member 310 moving towards the locking structure 500, at least a part of the limiting member 310 abuts against the first guiding surface 331, and under the action of the first guiding surface 331, it moves radially relative to the linkage rod 520, resulting in the limiting member 310 being disengaged from the limiting cooperation with the linkage rod 520.

[0037] When the limiting tongue 510 is not aligned with the limiting groove 111, the first driving member 400 drives the linkage rod 520, so that the limiting tongue 510 can abut against the main load-bearing beam 100. At this time, the limiting tongue 510 is not embedded in the limiting groove 111, so the first carriage 300 can move relative to the main load-bearing beam 100. During the further movement of the first driving member 400, the acting force of the linkage rod 520 on the second elastic member 320 can be transmitted to the first carriage 300 through the second elastic member 320, so that the first carriage 300 can move relative to the main load-bearing beam 100. When the limiting tongue 510 is aligned with the limiting groove 111, the limiting tongue 510 can enter at least partially into the limiting groove 111 under the action of the first elastic member 530. The linkage rod 520 continues to move under the drive of the first driving member 400, so that the second elastic member 320 continues to deform and the limiting member 310 continues to move. During the continuous movement of the limiting member 310, the first trigger member 330 can push the limiting member 310 to move relative to the linkage rod 520, so that the linkage rod 520 can be disengaged from the limiting cooperation with the limiting member 310, so that the linkage rod 520 can move relative to the first carriage 300 in the first extending direction and the second extending direction.

[0038] Referring to Figure 11 , the limiting member 310 has a first hole position 311 and a second hole position 312. The aperture or hole width of the first hole position 311 is smaller than that of the second hole position 312. The first hole position 311 and the second hole position 312 are communicated. Referring to Figure 10 , the linkage rod 520 can pass through the limiting member 310 from the first hole position 311 and the second hole position 312.

[0039] Optionally, a convex limiting structure is provided on the linkage rod 520. The size of the convex limiting structure is smaller than that of the second hole position 312. When the convex limiting structure is aligned with the second hole position 312, the convex limiting structure can pass through the limiting member 310 from the second hole position 312. The size of the convex limiting structure is larger than that of the first hole position 311. When the convex limiting structure is aligned with the first hole position 311, the convex limiting structure cannot pass through the limiting member 310 from the second hole position 312.

[0040] The first trigger member 330 can push the limiting member 310 to move relative to the linkage rod 520, so that the convex limiting structure is switched from being aligned with the first hole position 311 to being aligned with the second hole position 312. Specifically, Figure 12 shows a state diagram in which the convex limiting structure is aligned with the first hole position 311. Figure 13 shows a state diagram in which the convex limiting structure is aligned with the second hole position 312. Exemplarily, the convex limiting structure can be the second trigger member 522 described in the following embodiments.

[0041] In some embodiments, the second elastic member 320 can be elastically deformed along the moving direction of the linkage rod 520, and can also be bent and deformed toward the linkage rod 520. The limiting member 310 is connected to the second elastic member 320, so that the second elastic member 320 can also assist the limiting member 310 to move radially of the linkage rod 520. Exemplarily, the elastic force generated by the second elastic member 320 can drive the limiting member 310 to move radially of the linkage rod 520 relative to the linkage rod 520, so that the linkage rod 520 passes through the limiting member 310 from the second hole position 312 and is switched to the linkage rod 520 passing through the limiting member 310 from the first hole position 311.

[0042] In some alternative embodiments, the second elastic member 320 can be a helical spring, and the aperture of the second elastic member 320 is larger than the radial dimension of the linkage rod 520, so that the second elastic member 320 can be bent radially toward the linkage rod 520 relative to the linkage rod 520. Specifically, the second elastic member 320 is sleeved on the linkage rod 520, and one end of the second elastic member 320 is fixedly connected to the first carriage 300, and the other end is connected to the limiting member 310. Referring to Figure 10In some alternative embodiments, the first guiding surface 331 of the first trigger member 330 has an avoidance groove, and at least a part of the helical spring is located in the avoidance groove so that the second elastic member 320 can slide along the avoidance groove. The width of the limiting member 310 is greater than the width of the avoidance groove so that the limiting member 310 can abut against the first guiding surface 331.

[0043] In some embodiments, during the process of the linkage rod 520 driving the limiting tongue 510 to switch from the released limiting cooperation state to the limiting cooperation state, the linkage rod 520 will drive the second elastic member 320 to be compressed. When the limiting tongue 510 abuts against the surface of the main load-bearing beam 100 and does not engage with the limiting groove 111, the elastic force generated by the second elastic member 320 gradually increases until the elastic force generated by the second elastic member 320 is greater than the resistance to the relative movement between the first carriage 300 and the main load-bearing beam 100. Further, during the continuous movement of the linkage rod 520, the limiting tongue 510 will move to a position opposite to the limiting groove 111, and the limiting tongue 510 will directly engage with the limiting groove 111 under the action of the first elastic member 530 or the linkage rod 520, thereby increasing the resistance to the relative movement between the first carriage 300 and the main load-bearing beam 100, that is, the elastic force generated by the second elastic member 320 is no longer able to push the first carriage 300 to move relative to the main load-bearing beam 100, and thus the second elastic member 320 will continue to be compressed under the action of the linkage rod 520. Further, during the process of the second elastic member 320 being continuously compressed, the first trigger member 330 can push the limiting member 310 to move relative to the linkage rod 520, so that the linkage rod 520 can be disengaged from the limiting cooperation with the limiting member 310. The second elastic member 320 can be reset under the action of the elastic force after the linkage rod 520 is disengaged from the limiting cooperation with the limiting member 310.

[0044] In some embodiments, the first carriage 300 is further provided with a limiting block 340. When the limiting member 310 is disengaged from the limiting cooperation with the linkage rod 520, the second elastic member 320 can push the limiting member 310 to abut against the limiting block 340. This embodiment can limit the movement range of the limiting member 310 through the limiting block 340.

[0045] In some embodiments, a second trigger member 522 is provided on the linkage rod 520. The second trigger member 522 has a second guiding surface 5221. During the process of the linkage rod 520 driving the limiting tongue 510 to switch from the limiting cooperation with the main load-bearing beam 100 to the released limiting cooperation with the main load-bearing beam 100, at least a part of the limiting member 310 abuts against the second guiding surface 5221 and moves relative to the linkage rod 520 along the radial direction of the linkage rod 520 under the action of the second guiding surface 5221, so that the limiting member 310 can be in limiting cooperation with the linkage rod 520.

[0046] In this embodiment, during the process of the first driving member 400 driving the limiting tongue 510 to switch from being in limiting cooperation with the main load-bearing beam 100 to being released from the limiting cooperation with the main load-bearing beam 100, the second triggering member 522 can pass through the second hole 312 of the limiting member 310, so as to prepare for the second triggering member 522 to be in limiting abutment with the limiting member 310 during the subsequent process of the first driving member 400 driving the limiting tongue 510 to switch from being released from the limiting cooperation with the main load-bearing beam 100 to being in limiting cooperation with the main load-bearing beam 100.

[0047] Referring to Figure 1 and Figure 2 , the digital model prefabricated self-adjusting sling further includes a second carriage 600, a second driving member 700 and a lifting jack 800. The lifting jack 800 can be detachably connected to the lifting point. The second carriage 600 is used to connect the lifting jack 800 and the secondary load-bearing beam 200. The second driving member 700 is connected to the secondary load-bearing beam 200 and the second carriage 600, and is used to drive the second carriage 600 to move along the extension direction of the secondary load-bearing beam 200.

[0048] In some embodiments, the structure of the second carriage 600 can be the same as that of the first carriage 300, and has the same or similar technical effects as the first carriage 300. This embodiment will not be elaborated one by one.

[0049] In some embodiments, the second carriage 600 is provided with a locking structure 500, and the second driving member 700 is connected to the locking structure 500 provided on the second carriage 600.

[0050] In some alternative embodiments, as Figure 1 and Figure 2 shown, anti-detachment structures 120 are provided at both ends of the main load-bearing beam 100 and the secondary load-bearing beam 200. The anti-detachment structures 120 can be in limiting abutment cooperation with the first carriage 300 or the second carriage 600. The anti-detachment structures 120 are beneficial to preventing the first carriage 300 from slipping off both ends of the main load-bearing beam 100. And it is beneficial to preventing the second carriage 600 from slipping off both ends of the secondary load-bearing beam 200.

[0051] In some embodiments, the digital model prefabricated self-adjusting sling further includes a damping member 130. Exemplarily, the damping member 130 is connected to the first carriage 300 and the main load-bearing beam 100 to increase the damping of the relative movement between the first carriage 300 and the main load-bearing beam 100, which is beneficial to preventing the relative movement between the first carriage 300 and the main load-bearing beam 100 during the state switching process of the locking structure 500, and is beneficial to avoiding the impact force of the first driving member 400 on the locking structure 500. Exemplarily, the damping member 130 can be realized by the sliding friction between a rubber sleeve and a guide rod.

[0052] It should be noted that the damping member 130 can adopt all resistance structures that can be used for the linear sliding resistance. Therefore, the specific structure of the damping member 130 will not be elaborated in this application.

[0053] In some alternative embodiments, such as Figure 2 shown, the digital modular assembly self-adjusting sling further includes a rope splitting plate 900 and a steel rope 1000. Specifically, the rope splitting plate 900 and the steel rope 1000 can be selected from the rope splitting plate 900 and the steel rope 1000 in the prior art as needed, and are arranged on the main load-bearing beam 100 by adopting corresponding solutions, so that the digital modular assembly self-adjusting sling can be connected to a crane through the rope splitting plate 900 and the steel rope 1000.
