Description

Technical Field

[0001] The present invention belongs to the technical field of lifting and transferring equipment for precast walls, and particularly relates to a transferring equipment for precast wall installation construction. Background Technique

[0002] Under the industry background of "vigorously developing prefabricated buildings, promoting the transformation and upgrading of traditional construction models, and realizing building industrialization and residential industrialization", prefabricated walls are widely used in prefabricated buildings. The walls are first prefabricated in the factory and then transported to the construction site for lifting, transferring and installation. However, at present, on the construction site, when lifting and transporting precast slabs, most of them use tower crane steel wires to lift and transfer precast wall panels. When lifting and transferring, the steel wires are connected to the reserved steel bars or hanging rings on the wall panel through annular buckles or hooks. After the tower crane transfers the wall panel to the predetermined height at the installation position, by means of manual alignment, the sleeve at the bottom of the wall panel is aligned with the reserved steel bars on the building floor or floor slab, and then the steel bars are inserted into the sleeve by lowering the wall body. Then, the wall body is temporarily fixed by installing diagonal braces, and then the connection structure between the steel wire and the wall body can be removed. However, the commonly used annular buckles and hooks need to be manually removed. During the removal process, workers need to climb onto the scaffolding to reach the annular buckles or hooks for removal. At this time, the wall body is not yet poured and fixed, and most precast walls are used for the exterior walls of buildings. Therefore, there are relatively large safety hazards during the process of removing the annular buckles or hooks, and the annular buckles usually also use nuts to seal the openings, and the removal process is relatively cumbersome. Summary of the Invention

[0003] To solve the deficiencies of the prior art, the present invention provides a transferring equipment for precast wall installation construction, which can automatically unlock the connection with the precast wall without manual operation, and the unlocking process is fast.

[0004] To achieve the purpose of the present invention, the following scheme is proposed:

[0005] A transferring equipment for precast wall installation construction, casting grooves are reserved at both the top and bottom of the precast wall. Along the length direction at the same height position in the casting groove, multiple steel bars are provided, and the steel bars are all perpendicular to the side surface of the precast wall.

[0006] The transferring equipment includes: a hanging beam, a sliding rod and a clamping block.

[0007] A steel wire connected to a lifting device is provided at the top of the hanging beam. A plurality of card slots are opened along the length direction at the bottom of the hanging beam. An installation hole is opened along the length direction inside the hanging beam, and the installation hole is communicated with the card slots;

[0008] The sliding rod is inserted into the installation hole. Connecting rods with the same number as the card slots are provided at the bottom of the sliding rod. Support rods with the same distance from the sliding rod are provided at the lower ends of the connecting rods. The support rods all face the rear end of the sliding rod, and there is a gap between the ends of adjacent support rods. There is a gap between the support rods and the roots of the card slots. The sliding rod is movably arranged along the length direction of the hanging beam;

[0009] Multiple blocks are provided on both sides of the hanging beam corresponding to the card blocks. When the sliding rod moves backward, the connecting rod pushes the card block to swing outward from the hanging beam;

[0010] When the support rod is between adjacent card slots, the gap between adjacent support rods is aligned with the card slot. The card block is located inside the hanging beam and between two adjacent connecting rods.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. In the process of removing and transferring the connection structure between the equipment and the precast wall, this solution does not require manual operation, the unlocking process is more convenient and safer.

[0013] 2. When connecting the precast wall, multiple connection points can be achieved simultaneously by moving the sliding rod. Similarly, when unlocking, moving the sliding rod can unlock multiple connection points simultaneously, with higher connection and unlocking efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will describe the implementation manners of the present invention in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0033] A transfer device for precast wall installation and construction, used for hoisting and transferring precast walls, such as Figure 1As shown, casting grooves 91 are reserved at both the top and bottom of the precast wall. At the same height position along the length direction in the casting grooves 91, multiple steel bars 92 are provided. The steel bars 92 are all perpendicular to the side surface of the precast wall. The purpose of setting the casting grooves 91 is to increase the amount of cement poured between the precast wall and the floor slab after installing the precast wall, thereby improving the installation strength of the precast wall panel. And by setting the exposed steel bars 92 in the casting grooves 91, it can not only improve the connection strength between the precast wall and the floor surface after installation, but also ensure the structural strength of the casting grooves 91, preventing the casting grooves 91 from cracking during the transportation and installation construction process. Both ends of the steel bars 92 are embedded in the precast wall panel.

[0034] Combined with Figures 1 to 5 and 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.

[0035] The top of the suspension beam 1 is used to connect the steel wire of the lifting device. When lifting, the suspension beam 1 is in a horizontal posture. A plurality of card slots 11 are opened along the length direction at the bottom of the suspension beam 1. An installation hole 12 is opened along the length direction inside the suspension beam 1, and the installation hole 12 communicates with the card slots 11.

[0036] The sliding rod 2 is inserted into the installation hole 12. At the bottom of the sliding rod 2, there are connecting rods 21 with the same number as the card slots 11. At the lower ends of the connecting rods 21, there are support rods 22 at the same distance from the sliding rod 2. The support rods 22 all face 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 root of the card slots 11 for accommodating the steel bars 92. The sliding rod 2 is movably arranged along the length direction of the suspension beam 1. Specifically, a linear motor can be arranged 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 that the support rods 22 all face the rear end of the sliding rod 2 here is to facilitate the understanding of the solution and the description of subsequent associated mechanisms, and does not limit the front and rear directions of the sliding rod 2.

[0037] A plurality of clamping blocks 3 are provided on both sides corresponding to the suspension beam 1. The clamping blocks 3 are rotatably arranged between adjacent card slots 11. Specifically, it means that the clamping blocks 3 are arranged on the side plate entity between adjacent card slots 11 on the suspension beam 1. The rotation direction of the clamping blocks 3 is perpendicular to the bottom surface of the suspension beam 1. When the sliding rod 2 moves backward, the connecting rod 21 pushes the clamping blocks 3 to swing outward from the suspension beam 1.

[0038] As Figure 13 、 Figure 14 shown, when the support rods 22 are between adjacent card slots 11, the gap between adjacent support rods 22 is aligned with the card slots 11 to facilitate the insertion of the steel bars 92. The clamping blocks 3 are located inside the suspension beam 1 and between adjacent two connecting rods 21.

[0039] When connecting precast walls, the following main steps are included:

[0040] First step, insert the lower end of the lifting beam 1 into the casting groove 91 at the top of the precast wall panel.

[0041] Second step, by moving the sliding rod 2, make the support rod 22 hidden in the installation hole 12 between adjacent card slots 11, so that the interval between adjacent support rods 22 is aligned with the card slot 11, and then use some or all of the card slots 11 at the bottom of the lifting beam 1 to clamp outside the steel bar 92 at an appropriate position.

[0042] Third step, move the sliding rod 2 backward until the support rod 22 is inserted into the installation hole 12 communicating with the rear card slot 11, so as to lock the steel bar 92 in the card slot 11 by using the support rod 22. And during the process of moving the sliding rod 2 backward, use the connecting rod 21 to push the clamping blocks 3 on both sides of the lifting beam 1 to swing outward, and use the outer side of the clamping block 3 to abut against the inner wall of the casting groove 91 to prevent the lifting beam 1 from moving along the length direction of the steel bar 92 in the casting groove 91, so as to ensure the connection stability between the transfer device and the precast wall, and can effectively reduce the sway of the precast wall during the lifting and installation process.

[0043] Fourth step, the lifting device hoists the precast wall through the steel wire and transfers it to the installation construction position for installation.

[0044] After the precast wall is installed, use the diagonal strut to fix it, and then the transfer device can be removed. When removing, first remove the tension of the steel wire on the lifting beam 1, and use the root of the card slot 11 to support on the steel bar 92. The purpose of this operation is to separate the support rod 22 from the steel bar 92 to facilitate the movement of the support rod 22; then move the sliding rod 2 forward to pull out the support rod 22 from the installation hole 12 behind the corresponding card slot 11 until the support rod 22 moves to the installation hole 12 between adjacent card slots 11. At this time, the interval between adjacent support rods 22 is aligned with the card slot 11. Finally, lift the lifting beam 1 upward to automatically separate the card slot 11 from the steel bar 92 to achieve the purpose of automatic unlocking. When the sliding rod 2 moves forward, the thrust of the connecting rod 21 on the clamping block 3 will also disappear, so the contact pressure between the clamping block 3 and the side wall of the casting groove 91 will also automatically disappear to avoid affecting the removal of the lifting beam 1 from the casting groove 91. This solution does not require manual operation during the process of removing the connection structure between the transfer device and the precast wall, and the unlocking process is more convenient and safer.

[0045] Preferably, as Figure 2 and Figures 11 to 14As shown in the figure, through holes 101 are formed in pairs on both sides of the lifting beam 1. One end of the clamping block 3 is rotatably arranged in the through hole 101, and the other end of the clamping block 3 is swingably arranged and faces the rear end of the sliding rod 2. The thickness of the clamping block 3 is less than or equal to the thickness of the lifting beam 1 and greater than half of the thickness of the lifting beam 1, so that the clamping blocks 3 on both sides of the lifting beam 1 have a larger support width after being unfolded, so as to adapt to a wider pouring groove 91. The clamping blocks 3 on both sides of the lifting beam 1 are arranged staggeredly along the length direction of the lifting beam 1. It can also be understood that among each pair of through holes 101 on both sides of the lifting beam 1, only the through hole 101 on one side is provided with a clamping block 3. In this way, the empty through hole 101 can be used to accommodate the clamping block 3 installed on the opposite side, so that when the clamping block 3 is retracted into the lifting beam 1, the transfer device has a smaller width, thus facilitating the insertion of the transfer device into the pouring groove 91.

[0046] Preferably, as Figure 12 shown, the clamping block 3 has a triangular block structure, and its inclined surface faces the inside of the lifting beam 1. The corner opposite to the inclined surface is used to abut against the inner wall of the pouring groove 91. When the clamping block 3 is received inside the lifting beam 1, the outer side surface of the clamping block 3 is aligned with the outer side wall of the lifting beam 1 or hidden inside the outer side wall of the lifting beam 1, and the inclined surface is within the range of the mounting hole 12, so as to facilitate the sliding contact between the connecting rod 21 and the inclined surface of the clamping block 3, so as to achieve the purpose of pushing the clamping block 3 to unfold outward.

[0047] As another preferred solution, as Figure 12 shown, a cylindrical roller 32 is provided at the position where the connecting rod 21 contacts the clamping block 3. The clamping block 3 is pushed to swing by rolling contact between the cylindrical roller 32 and the clamping block 3, which can effectively reduce the wear between parts and reduce the resistance of the sliding rod 2 to move.

[0048] Preferably, as Figure 12 shown, a spring piece 31 is provided on the outer side wall of the lifting beam 1 corresponding to the outer side of the clamping block 3. The spring piece 31 generates a pressure towards the inside of the lifting beam 1 on the clamping block 3. During the forward movement of the sliding rod 2, the spring piece 31 will automatically push the clamping block 3 into the lifting beam 1 to achieve the purpose of automatically retracting the clamping block 3, so that the clamping block 3 is quickly and completely separated from the pouring groove 91 and to prevent the lifting beam 1 from being blocked when inserted into the pouring groove 91.

[0049] Preferably, as Figure 3 、 Figure 8As shown, support slopes 221 are provided at the tops of the support rods 22, which are inclined towards the rear of the sliding rod 2. During the process of locking the steel bars 92, the support slopes 221 can be used to push the steel bars 92 towards the root of the card slot 11, and the distance between the support slope 221 and the root of the card slot 11 is reduced, thereby reducing the movement space of the steel bars 92 in the card slot 11, reducing the relative movement space between the precast wall and the transfer device, and improving the stability during the lifting process; and setting the support slope 221 will also correspondingly increase the cross-sectional area of the support rod 22, improving the structural strength of the support rod 22. The card slot 11 is a V-shaped structure with an opening facing downwards, so that the card slot 11 has a larger opening size, facilitating the connection between the card slot 11 and the steel bars 92. On the other hand, with the above structural design, when connecting the steel bars 92, the steel bars 92 can be clamped within the acute angle formed between the support slope 221 and one of the inner walls of the card slot 11, and the acute angle is used to limit the position of the steel bars 92 in the length direction of the lifting beam 1, preventing the precast wall from moving relatively along the length direction of the lifting beam 1, reducing the sway of the precast wall during the lifting process, and helping to ensure the stability of the precast wall during the lifting process.

[0050] Preferably, as Figure 2 , Figure 7 and Figure 14 shown, a driving motor 4 is provided at the rear end of the lifting beam 1, a screw rod 41 is coaxially provided on its main shaft, a threaded hole matching the screw rod 41 is opened at the rear end of the sliding rod 2, and the screw rod 41 is arranged in the threaded hole. By driving the screw rod 41 to rotate through the driving motor 4, the sliding rod 2 can be driven to move along the length direction. As Figure 10 shown, an annular plate 411 is coaxially provided at one end of the screw rod 41 connected to the driving motor 4, a thrust bearing 42 coaxial with the screw rod 41 is embedded in the rear end face of the lifting beam 1, and the annular plate 411 abuts against the housing of the thrust bearing 42 facing the rear end of the lifting beam 1, used to prevent the screw rod 41 from moving towards the front end of the lifting beam 1 and at the same time maintaining the smoothness of the screw rod 41 during rotation. When the support slope 221 is provided at the top of the support rod 22, during the lifting process, the support slope 221 is subjected to the pressure generated by the steel bars 92 on it. Since the support slope 221 faces above the rear end of the sliding rod 2, part of the component force of the pressure generated by the steel bars 92 will force the sliding rod 2 to move forward, and then drive the screw rod 41 to move towards the front end of the lifting beam 1 through the threaded hole. In this way, the main shaft of the driving motor 4 will bear a large axial tension, affecting the normal operation and service life of the driving motor 4; the above solution sets the thrust bearing 42 to bear the axial pressure of the screw rod 41, preventing the screw rod 41 from moving towards the front end of the lifting beam 1, thereby preventing the main shaft of the driving motor 4 from bearing axial tension, ensuring the operating stability of the driving motor 4, and preventing the screw rod 41 from separating from the main shaft of the driving motor 4, resulting in accidental unlocking of the support rod 22.

[0051] Preferably, in combination with Figure 6 ,Figure 8 , Figure 9 and Figure 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 card slots 11. 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 as an ellipse. A connecting shaft 52 is provided in the middle of the locking tongue 51. The connecting shaft 52 is perpendicular to the cross-section of the locking tongue 51, and the connecting shaft 52 is parallel to the length direction of the mounting hole 12. The locking tongue 51 is rotatably arranged around the connecting shaft 52. When the locking tongue 51 is in its natural state, its lower end is lower than the root of the card slot 11, and the upper end of the locking 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 card 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 card slot 11. At this time, the upper end of the locking tongue 51 is stuck through the locking hole 201, so as to prevent the sliding rod 2 from moving along the length direction during the lifting process by using the connection between the locking tongue 51 and the locking hole 201; when the locking tongue 51 tends to be in a horizontal state, the upper end of the locking 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 card slot 11. After the precast wall is installed, it is fixed by the diagonal strut, and then the transfer equipment can be removed. When removing, first remove the tension of the steel wire on the lifting beam 1. At this time, the steel bar 92 will move towards the root of the card slot 11. When the steel bar 92 contacts the lower end of the locking tongue 51, it will push the locking tongue 51 to swing around the connecting shaft 52. When the steel bar 92 contacts the bottom surface of the card slot 11, the upper end of the locking tongue 51 will move out of the locking hole 201, so as to achieve the purpose of separating the locking tongue 51 from the locking hole 201; then move the sliding rod 2 forward, and the upper end of the locking tongue 51 will slide into contact with the bottom surface of the sliding rod 2. At this time, the locking tongue 51 tends to be in a horizontal state. By moving the sliding rod 2, the support rod 22 is pulled out from the mounting hole 12 behind the corresponding card slot 11 until the support rod 22 moves into the mounting hole 12 between the adjacent card slots 11. At this time, the interval between the adjacent support rods 22 is aligned with the card slot 11; finally, lifting the lifting beam 1 upwards can automatically separate the card slot 11 from the steel bar 92, achieving the purpose of automatic unlocking. Specifically, as Figure 6 shown, the connecting shaft 52 passes through a rectangular frame 53. The locking tongue 51 is located inside the rectangular frame 53. The two ends of the rectangular frame 53 are respectively connected to the inner walls on both sides of the mounting hole 12, specifically, it can be connected by screws or by welding; as a further preferred solution, the locking tongue 51 is arranged at the position corresponding to the card slot 11 in the middle of the lifting beam 1.

[0052] Further preferably, the connecting shaft 52 and the axis of the locking tongue 51 are eccentrically arranged. As Figure 16As shown in the figure, where a represents the axis of the connecting shaft 52 and 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 eccentrically structured. For example, when the cross-section of the locking tongue 51 is diamond-shaped, the axis of the diamond is eccentrically arranged with the axis of the connecting shaft 52; when the cross-section of the locking tongue 51 is oval-shaped, the axis of the oval is eccentrically arranged with the axis of the connecting shaft 52. The design of the eccentric structure makes the locking tongue 51 in an inclined state when it is in the natural state, so that the steel bar 92 can smoothly push the locking tongue 51 to swing after contacting it, to prevent the contact point between the steel bar 92 and the locking tongue 51 and the axis of the connecting shaft 52 from being in the same vertical plane when the locking tongue 51 is completely vertical, resulting in jamming of the locking tongue 51 and affecting the swing of the locking tongue 51.

[0053] Preferably, as Figure 2 shown, a guide rod 13 is provided in parallel in the middle above the hanging beam 1. A ring 14 is provided at the lower end of the steel wire for connecting the hanging beam 1. The ring 14 is sleeved on the guide rod 13, and the ring 14 is movably arranged along the length direction of the guide rod 13 to adjust the relative position of the steel wire in the direction of the hanging beam 1 to maintain the balance of the precast wall during the lifting process. The ring 14 can be adjusted and limited by the tightening screws provided in parallel at both ends of the guide rod 13.

[0054] Further preferably, as Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 13 shown, an adjusting screw rod 15 is provided in parallel on one side of the hanging beam 1 corresponding to the guide rod 13. The adjusting screw rod 15 is coaxially arranged on the main shaft of an adjusting motor 17. A slider 16 is provided on the adjusting screw rod 15. The slider 16 is provided with a pair of spaced-apart dial plates 161. The guide rod 13 passes through the two dial plates 161. The ring 14 is located between the two dial plates 161. A horizontal detector 18 is provided on the hanging beam 1. After the lifting, the transfer device determines the inclination of both ends of the hanging beam 1 through the position signal of the hanging beam 1 detected by the horizontal detector 18. When the height of the rear end of the hanging beam 1 is lower, the adjusting motor 17 is driven to rotate the adjusting screw rod 15 to drive the slider 16 to move towards the rear end of the hanging beam 1, and at the same time, it will also drive the ring 14 to move towards the rear end of the hanging beam 1, so that the connection point between the steel wire and the hanging beam 1 moves towards the rear end of the hanging beam 1 until the horizontal detector 18 detects that the hanging beam 1 is in a horizontal state. Through this design, even if the balance point of the precast wall is not found at the initial stage of connecting the precast wall, the above scheme can be used for automatic adjustment after the lifting to ensure that the precast wall is in a vertical state during the installation construction.

[0055] Preferably, as Figure 2 、 Figure 4 、 Figure 5As shown, a hook 6 is provided on the steel wire for connecting the suspension beam 1, and a hanging ring 19 is provided on one side of the suspension beam 1. The connection structure between the hook 6 and the hanging ring 19 is detachable; 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 this design is that precast walls are usually placed flat during transportation. Since the transfer device as a whole has a certain weight, it is not convenient for workers to insert the suspension beam 1 into the casting groove 91. After the hook 6 and the hanging ring 19 are provided, when the transfer device is lifted by the steel wire, the suspension beam 1 can be in a horizontal state, so that the suspension beam 1 can be easily inserted into the casting groove 91 in a horizontal state; when the support rod 22 positions the steel bar 92, lower the tension of the steel wire on the suspension beam 1, and then loosen the connection between the hook 6 and the hanging ring 19, and then the lifting operation can be carried out.

[0056] The above are only the preferred embodiments of the present invention, and do not represent the only or limit the present invention. Those skilled in the art should understand that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention all belong to the scope of protection of the present invention.
