Description

Technical Field

[0001] The invention belongs to the technical field of prefabricated wall lifting and transferring equipment, and in particular relates to a transfer equipment for prefabricated wall installation construction. Background Art

[0002] Under the industry background of "vigorously developing prefabricated buildings, promoting the transformation and upgrading of traditional construction models, and realizing the industrialization of construction and housing", prefabricated walls are widely used in prefabricated buildings. The wall is first prefabricated in the factory and then transported to the construction site for lifting and transfer and installation. However, at present, when lifting and transporting prefabricated panels at the construction site, most of them are lifted and transferred by tower crane wire ropes. During lifting and transfer, the steel wire is connected to the steel bars or hanging rings reserved on the wall panels through ring locks or hooks. After the tower crane transfers the wall panel to the predetermined height of the installation position, the sleeve at the bottom of the wall panel is aligned with the steel bars reserved on the building floor or slab by manual straightening, and then the steel bars are inserted into the sleeve by lowering the wall, and then the wall is temporarily fixed by installing diagonal braces, and then the connection structure between the steel wire and the wall can be removed. However, commonly used ring locks and hooks need to be manually removed. The removal process requires workers to climb onto the scaffolding to remove the ring locks or hooks. At this time, the wall has not been cast and fixed, and most prefabricated walls will be used for the exterior walls of buildings. Therefore, there are great safety hazards in the process of removing the ring locks or hooks. In addition, the ring locks usually use nuts to close the openings, and the removal process is relatively cumbersome. Summary of the invention

[0003] In order to solve the deficiencies of the prior art, the present invention provides a transfer device for prefabricated wall installation construction, which can automatically release the connection with the prefabricated wall without manual operation, and the unlocking process is quick.

[0004] In order to achieve the purpose of the present invention, the following scheme is proposed: A transfer device for prefabricated wall installation construction, the top and bottom of the prefabricated wall are both reserved with casting troughs, a plurality of steel bars are arranged at the same height position along the length direction in the casting trough, and the steel bars are all perpendicular to the side of the prefabricated wall.

[0005] The transfer equipment includes: a hanging beam, a sliding rod and a clamping block.

[0006] A steel wire connected to the lifting equipment is provided at the top of the hanging beam, a plurality of slots are provided at the bottom of the hanging beam along the length direction, and a mounting hole is provided inside the hanging beam along the length direction, and the mounting hole is connected to the slot; The sliding rod is inserted into the mounting hole, and the bottom of the sliding rod is provided with connecting rods with the same number as the card slots, and the lower ends of the connecting rods are provided with support rods with the same distance as the sliding rods, and the support rods are all toward the rear end of the sliding rod, and there is a gap between the ends of adjacent support rods, and there is a gap between the support rods and the root of the card slot, and the sliding rod is arranged to move along the length direction of the suspension beam; There are multiple blocks on both sides of the corresponding hanging beam. When the sliding rod moves to the rear end, the connecting rod pushes the block to swing to the outside of the hanging beam; When the support rods are located between adjacent slots, the intervals between the adjacent support rods are aligned with the slots, and the clamping block is located in the suspension beam and between two adjacent connecting rods.

[0007] The beneficial effects of the present invention are: 1. This solution does not require manual operation during the process of dismantling the connection structure between the transfer equipment and the prefabricated wall, and the unlocking process is more convenient and safer.

[0008] 2. When connecting prefabricated walls, multiple connection points can be achieved at the same time by moving the sliding rod. Similarly, when unlocking, moving the sliding rod can unlock multiple connection points at the same time, which has higher connection and unlocking efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] A transfer device for prefabricated wall installation construction, used for hoisting and transferring prefabricated walls, such as Figure 1As shown, a casting trough 91 is reserved at the top and bottom of the prefabricated wall. A plurality of steel bars 92 are arranged at the same height along the length direction in the casting trough 91. The steel bars 92 are perpendicular to the sides of the prefabricated wall. The purpose of setting the casting trough 91 is to increase the amount of cement pouring between the prefabricated wall and the floor slab after the prefabricated wall is installed, so as to improve the installation strength of the prefabricated wall panel. The exposed steel bars 92 are arranged in the casting trough 91, which can not only improve the connection strength between the prefabricated wall and the floor after installation, but also ensure the structural strength of the casting trough 91, so as to prevent the casting trough 91 from cracking during transportation and installation. Both ends of the steel bars 92 are embedded in the prefabricated wall panel.

[0029] Combination Figures 1 to 5 as well as Figure 7 , Figures 11 to 14 As shown, the transfer device includes a suspension beam 1, a sliding rod 2 and a clamping block 3.

[0030] The top of the lifting beam 1 is used to connect the steel wire of the lifting equipment. When lifting, the lifting beam 1 is in a horizontal posture. The bottom of the lifting beam 1 is provided with multiple slots 11 along the length direction. The inside of the lifting beam 1 is provided with mounting holes 12 along the length direction, and the mounting holes 12 are connected to the slots 11.

[0031] The sliding rod 2 is inserted into the mounting hole 12. The bottom of the sliding rod 2 is provided with connecting rods 21 with the same number as the slots 11. The lower ends of the connecting rods 21 are provided with support rods 22 with the same distance as the sliding rod 2. The support rods 22 are all facing the rear end of the sliding rod 2, and there is a gap between the ends of adjacent support rods 22. There is a gap between the support rods 22 and the roots of the slots 11 for accommodating the steel bars 92. The sliding rod 2 is arranged to move along the length direction of the suspension beam 1. Specifically, a linear motor can be provided at the end of the suspension beam 1 to directly drive the sliding rod 2 to move. The support rods 22 can also face the front end of the sliding rod 2. The purpose of describing here that the support rods 22 are all facing the rear end of the sliding rod 2 is to facilitate the understanding of the scheme and the description of the subsequent related mechanisms, and does not limit the front and rear directions of the sliding rod 2.

[0032] There are multiple blocks 3 on both sides corresponding to the suspension beam 1, and the blocks 3 are rotatably arranged between adjacent slots 11. Specifically, the blocks 3 are arranged on the side plate entity between adjacent slots 11 on the suspension beam 1. The rotation direction of the blocks 3 is perpendicular to the bottom surface of the suspension beam 1. When the sliding rod 2 moves to the rear end, the connecting rod 21 pushes the blocks 3 to swing to the outside of the suspension beam 1.

[0033] like Fig.13 , Fig.14 As shown, when the support rods 22 are located between adjacent slots 11 , the intervals between adjacent support rods 22 are aligned with the slots 11 to facilitate the insertion of the steel bars 92 . The clamping block 3 is located in the suspension beam 1 and between two adjacent connecting rods 21 .

[0034] The following steps are mainly involved in connecting prefabricated walls: The first step is to insert the lower end of the hanging beam 1 into the casting trough 91 at the top of the prefabricated wall panel; In the second step, the sliding rod 2 is moved so that the support rod 22 is hidden in the mounting hole 12 between adjacent slots 11, so that the interval between adjacent support rods 22 is aligned with the slots 11, and then part or all of the slots 11 at the bottom of the suspension beam 1 are used to clamp the outside of the steel bar 92 at the appropriate position.

[0035] The third step is to move the sliding rod 2 toward the rear end until the support rod 22 is inserted into the mounting hole 12 connected to the rear slot 11, so that the support rod 22 is used to lock the steel bar 92 in the slot 11, and in the process of moving the sliding rod 2 backward, the connecting rod 21 is used to push the blocks 3 on both sides of the hanging beam 1 to swing outward, and the outer side of the blocks 3 is used to abut against the inner wall of the casting trough 91 to prevent the hanging beam 1 from moving in the casting trough 91 along the length direction of the steel bar 92, so as to ensure the connection stability between the transfer equipment and the prefabricated wall, and effectively reduce the shaking of the prefabricated wall during lifting and installation.

[0036] In the fourth step, the lifting equipment lifts the prefabricated wall through the steel wire and transfers it to the installation construction site for installation.

[0037] After the prefabricated wall is installed, it is fixed with a diagonal brace, and then the transfer equipment can be removed. When removing, first remove the tension of the steel wire on the hanging beam 1, and use the root of the slot 11 to support the steel bar 92. The purpose of this operation is to separate the support rod 22 from the steel bar 92, so as to facilitate the movement of the support rod 22; then move the sliding rod 2 forward, and pull the support rod 22 out of the mounting hole 12 behind the corresponding slot 11, until the support rod 22 moves into the mounting hole 12 between the adjacent slots 11, and the interval between the adjacent support rods 22 is aligned with the slot 11. Finally, lift the hanging beam 1 upward to automatically separate the slot 11 from the steel bar 92, so as to achieve the purpose of automatic unlocking. When the sliding rod 2 moves forward, the thrust of the connecting rod 21 on the block 3 will also disappear, so the contact pressure between the block 3 and the side wall of the casting trough 91 will also disappear automatically, so as to avoid affecting the removal of the hanging beam 1 from the casting trough 91. This solution does not require manual operation during the process of dismantling the connection structure between the transfer equipment and the prefabricated wall, and the unlocking process is more convenient and safer.

[0038] Preferably, Figure 2 and Figures 11 to 14As shown, pairs of through holes 101 are provided on both sides of the suspension beam 1, one end of the block 3 is rotatably disposed in the through hole 101, and the other end of the block 3 is swingably disposed and faces the rear end of the sliding rod 2, and the thickness of the block 3 is less than or equal to the thickness of the suspension beam 1, and greater than half of the thickness of the suspension beam 1, so that the blocks 3 on both sides of the suspension beam 1 have a larger support width after being unfolded to adapt to the wider casting trough 91, and the blocks 3 on both sides of the suspension beam 1 are staggered along the length direction of the suspension beam 1, and it can also be understood that in each pair of through holes 101 on both sides of the suspension beam 1, only one side of the through hole 101 is installed with a block 3, so that the empty through hole 101 can be used to accommodate the block 3 installed on the opposite side, so that when the block 3 is retracted into the interior of the suspension beam 1, the transfer equipment has a smaller width, thereby facilitating the insertion of the transfer equipment into the casting trough 91.

[0039] As a preferred example, Fig.12 As shown, the block 3 is a triangular block structure, with its inclined surface facing the inside of the hanging beam 1, and the angle opposite to the inclined surface is used to abut the inner wall of the casting groove 91. When the block 3 is received in the hanging beam 1, the outer side surface of the block 3 is aligned with the outer side wall of the hanging beam 1 or hidden inside the outer side wall of the hanging beam 1, and the inclined surface is located within the range of the mounting hole 12, so that the connecting rod 21 can slide in contact with the inclined surface of the block 3, thereby achieving the purpose of pushing the block 3 to expand outward. As another preferred solution, Fig.12 As shown, a cylindrical roller 32 is provided at the portion of the connecting rod 21 that contacts the block 3. The block 3 is pushed to swing by the rolling contact between the cylindrical roller 32 and the block 3, which can effectively reduce the wear between the parts and reduce the resistance to the movement of the sliding rod 2.

[0040] Preferably, Fig.12 As shown, a spring sheet 31 is provided on the outer side of the outer wall of the hanging beam 1 corresponding to the outer side of the block 3. The spring sheet 31 generates pressure toward the inside of the hanging beam 1 to the block 3. When the sliding rod 2 moves forward, the spring sheet 31 will automatically push the block 3 into the hanging beam 1 to achieve the purpose of automatically retracting the block 3, so that the block 3 can be quickly and completely separated from the casting trough 91, and avoid hindering the insertion of the hanging beam 1 into the casting trough 91.

[0041] Preferably, Figure 3 , Figure 8As shown, the top of the support rod 22 is provided with a support slope 221, which is inclined toward the rear of the sliding rod 2. In the process of locking the steel bar 92, the support slope 221 can be used to push the steel bar 92 to the root of the slot 11, and the distance between the support slope 221 and the root of the slot 11 is reduced, thereby reducing the activity space of the steel bar 92 in the slot 11, so as to reduce the relative movement space between the prefabricated wall and the transfer equipment, and improve the stability of the lifting process; and the provision of the support slope 221 will also increase the cross-sectional area of ​​the support rod 22 accordingly, improve the structural strength of the support rod 22, and the slot 11 is a V-shaped structure with the opening facing downward, so that the slot 11 has a larger opening size, thereby facilitating the connection between the slot 11 and the steel bar 92. On the other hand, by adopting the above-mentioned structural design, when connecting the steel bar 92, the steel bar 92 can be clamped in the acute angle formed between the supporting slope 221 and one of the inner walls of the clamping groove 11. The acute angle is used to limit the position of the steel bar 92 in the length direction of the suspension beam 1, thereby avoiding relative movement of the prefabricated wall along the length direction of the suspension beam 1, thereby reducing the shaking of the prefabricated wall during the lifting process and helping to ensure the stability of the prefabricated wall during the lifting process.

[0042] Preferably, Figure 2 , Figure 7 and Fig.14 As shown, the rear end of the suspension beam 1 is provided with a driving motor 4, and a screw 41 is coaxially provided on its main shaft. A threaded hole matching the screw 41 is provided on the rear end of the sliding rod 2. The screw 41 is arranged in the threaded hole. The driving motor 4 drives the screw 41 to rotate, thereby driving the sliding rod 2 to move along the length direction. Fig.10 As shown, an annular plate 411 is coaxially provided at one end of the screw 41 connected to the driving motor 4, and a thrust bearing 42 coaxial with the screw 41 is embedded in the rear end face of the suspension beam 1. The annular plate 411 abuts against the shell of the thrust bearing 42 toward the rear end of the suspension beam 1, which is used to prevent the screw 41 from moving toward the front end of the suspension beam 1 and at the same time maintain the smoothness of the screw 41 during rotation. When a supporting slope 221 is provided on the top of the support rod 22, during the lifting process, the supporting slope 221 is subjected to the pressure generated by the steel bar 92. Since the supporting slope 221 is directed toward the upper side of the rear end of the sliding rod 2, part of the pressure generated by the steel bar 92 will force the sliding rod 2 to move forward, and then drive the screw 41 to move toward the front end of the suspension beam 1 through the threaded hole. This will cause the main shaft of the drive motor 4 to be subjected to a large axial tension, affecting the normal operation and service life of the drive motor 4. The above-mentioned scheme sets a thrust bearing 42 to withstand the axial pressure of the screw 41 to prevent the screw 41 from moving toward the front end of the suspension beam 1, thereby preventing the main shaft of the drive motor 4 from being subjected to axial tension, so as to ensure the operating stability of the drive motor 4 and prevent the screw 41 from separating from the main shaft of the drive motor 4, which may cause the support rod 22 to be accidentally unlocked.

[0043] Preferably, combined Figure 6 , Figure 8 , Fig. 9 and Fig.15 As shown, a locking tongue 51 is provided in the mounting hole 12, and the locking tongue 51 is located at the root of one of the slots 11, and the cross section of the locking tongue 51 is diamond-shaped; as another preferred structure, the cross section of the locking tongue 51 can also be designed to be elliptical. A connecting shaft 52 is provided in the middle of the lock tongue 51, and the connecting shaft 52 is perpendicular to the cross section of the lock tongue 51, and the connecting shaft 52 is parallel to the length direction of the mounting hole 12. The lock tongue 51 is rotatably arranged around the connecting shaft 52. When the lock tongue 51 is in a natural state, its lower end is lower than the root of the slot 11, and the upper end of the lock tongue 51 is higher than the bottom surface of the sliding rod 2. A locking hole 201 is provided at the bottom of the sliding rod 2. When the support rod 22 blocks the opening of the slot 11, it can also be understood that when the sliding rod 2 moves backward to a predetermined position, the support rod 22 fixes the steel bar 92 in the slot 11. At this time, the upper end of the lock tongue 51 is inserted into the locking hole 201, so as to prevent the sliding rod 2 from moving along the length direction during the lifting process by utilizing the connection between the lock tongue 51 and the locking hole 201; when the lock tongue 51 tends to be in a horizontal state, the upper end of the lock tongue 51 is lower than the bottom surface of the sliding rod 2, and the lower end is flush with or higher than the bottom surface of the slot 11. After the prefabricated wall is installed, it is fixed with a diagonal brace, and then the transfer equipment can be removed. When removing, first remove the tension of the steel wire on the hanging beam 1. At this time, the steel bar 92 will move to the root of the slot 11. When the steel bar 92 contacts the lower end of the lock tongue 51, it will push the lock tongue 51 to swing around the connecting shaft 52. When the steel bar 92 contacts the bottom surface of the slot 11, the upper end of the lock tongue 51 will move out of the lock hole 201, thereby achieving the purpose of separating the lock tongue 51 from the lock hole 201; then move forward Move the sliding rod 2, the upper end of the locking tongue 51 will slide and contact with the bottom surface of the sliding rod 2, and the locking tongue 51 will tend to be horizontal. By moving the sliding rod 2, the support rod 22 is pulled out from the mounting hole 12 behind the corresponding slot 11 until the support rod 22 moves to the mounting hole 12 between the adjacent slots 11. At this time, the interval between the adjacent support rods 22 is aligned with the slot 11; finally, the lifting beam 1 is lifted upward to automatically separate the slot 11 from the steel bar 92, thereby achieving the purpose of automatic unlocking. Specifically, as Figure 6 As shown, the connecting shaft 52 is passed through a rectangular frame 53, the locking tongue 51 is located inside the rectangular frame 53, and the two ends of the rectangular frame 53 are respectively connected to the inner walls on both sides of the mounting hole 12, which can be connected by screws or welding; as a further preferred solution, the locking tongue 51 is arranged at a position corresponding to the slot 11 in the middle of the suspension beam 1.

[0044] Further preferably, the connecting shaft 52 and the axis of the locking tongue 51 are eccentrically arranged. Fig.16As shown, a represents the axis of the connecting shaft 52, b represents the axis of the locking tongue 51, and a and b are eccentrically designed. Specifically, it means that the axis of the connecting shaft 52 and the axis of the cross section of the locking tongue 51 are designed in an eccentric structure. For example, when the cross section of the locking tongue 51 is a rhombus, the axis of the rhombus is eccentrically set to the axis of the connecting shaft 52, and when the cross section of the locking tongue 51 is an ellipse, the axis of the ellipse is eccentrically set to the axis of the connecting shaft 52. The design of the eccentric structure makes the locking tongue 51 present an inclined state when it is in a natural state, so that the locking tongue 51 can be smoothly pushed to swing after the steel bar 92 contacts it, so as to prevent the locking tongue 51 from being stuck when the locking tongue 51 is completely vertical, and the contact point between the steel bar 92 and the locking tongue 51 and the axis of the connecting shaft 52 are in the same vertical plane, which affects the swing of the locking tongue 51.

[0045] Preferably, Figure 2 As shown, a guide rod 13 is provided in parallel in the middle part above the suspension beam 1, and a ring 14 is provided at the lower end of the steel wire connecting the suspension beam 1. The ring 14 is sleeved on the guide rod 13, and the ring 14 is movable along the length direction of the guide rod 13 to adjust the relative position of the steel wire in the direction of the suspension beam 1 to maintain the balance of the prefabricated wall during the lifting process. The ring 14 can be adjusted and limited by tightening screws arranged in parallel at both ends of the guide rod 13.

[0046] Further preferably, Figure 2 , Figure 4 , Figure 5 , Figure 7 and Fig.13 As shown, an adjusting screw 15 is provided parallel to one side of the corresponding guide rod 13 on the hanging beam 1, and the adjusting screw 15 is coaxially arranged on the main shaft of an adjusting motor 17. A slider 16 is provided on the adjusting screw 15, and the slider 16 is provided with a pair of spaced paddles 161. The guide rod 13 passes through the two paddles 161, and the ring 14 is located between the two paddles 161. A level detector 18 is provided on the hanging beam 1. After lifting, the transfer equipment determines the inclination of the two ends of the beam 1 through the position signal of the beam 1 detected by the level detector 18. When the rear end height of the beam 1 is low, the adjusting motor 17 drives the adjusting screw 15 to rotate to drive the slider 16 to move toward the rear end of the beam 1, and also drives the ring 14 to move toward the rear end of the beam 1, so that the connection point between the steel wire and the beam 1 moves toward the rear end of the beam 1 until the level detector 18 detects that the beam 1 is in a horizontal state. Through this design, even if the balance point of the prefabricated wall is not found in the early stage of connecting the prefabricated wall, the above scheme can be used to perform automatic adjustment after lifting to ensure that the prefabricated wall is in a vertical state during installation.

[0047] Preferably, Figure 2 , Figure 4 , Figure 5As shown, a hook 6 is provided on the steel wire used to connect the suspension beam 1, and a hanging ring 19 is provided on one side of the suspension beam 1, and a detachable connection structure is formed between the hook 6 and the hanging ring 19; when the hook 6 is connected to the hanging ring 19 and the steel wire lifts the suspension beam 1, the suspension beam 1 is in a horizontal state. The reason for adopting this design is that prefabricated walls are usually placed in a flat manner during transportation. Because the transfer equipment as a whole has a certain weight, it is not convenient to manually insert the suspension beam 1 into the casting trough 91. After the hook 6 and the hanging ring 19 are provided, the transfer equipment can be lifted by the steel wire so that the suspension beam 1 is in a horizontal state, so that the suspension beam 1 can be easily inserted into the casting trough 91 in a horizontal state; when the support rod 22 limits the steel bar 92, the tension of the steel wire on the suspension beam 1 is reduced, and then the connection between the hook 6 and the hanging ring 19 is released, and the lifting operation can be performed.

[0048] The above description is only a preferred embodiment of the present invention, and is not intended to be the only one or to limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
