Description

Technical Field

[0001] The present invention relates to the technical field related to the installation of ALC boards, and specifically to a multifunctional lifting and positioning device for ALC board installation and a usage method thereof. Background Art

[0002] ALC boards are autoclaved lightweight concrete boards mainly made of cement, lime, silica sand, etc. through an autoclaving process. It has various excellent properties such as light weight, high strength, heat insulation, sound insulation, and fire resistance, and is widely used in the fields of residential, commercial, and industrial buildings, and can be used as exterior wall boards, interior wall boards, floor slabs, roof slabs, etc.

[0003] In order to achieve rapid assembly of ALC boards, grooves and splicing protrusions are provided on both sides of the ALC boards. The grooves and splicing protrusions on two adjacent ALC boards are inserted together to achieve assembly. When the ALC board is connected to the wall, grooves or splicing protrusions can be pre-processed on the wall.

[0004] ALC boards have a certain mass, so generally auxiliary machinery is used for auxiliary installation during the installation of ALC boards. There is a robot for auxiliary installation of ALC boards, which includes a mobile chassis, a lifting mechanism, a rotating mechanism, and a clamping mechanism, integrating multiple functions such as lifting, rotating, tilting, and translation. Since one side of the ALC board needs to be spliced with the previous ALC board or the wall, the clamping mechanism of this robot is located on one side of the ALC board, making the splicing surface of the ALC board exposed.

[0005] However, with this clamping method, it is easy to occur that the clamping position is not at the center of the ALC board after the ALC board is clamped, resulting in easy deviation of the ALC board. At the same time, during the movement of the mobile chassis or the lifting of the ALC by the lifting mechanism, due to the inertial effect, the ALC board shifts relative to the clamping mechanism, resulting in that during the subsequent assembly process, since the ALC board is not at the required angle, it needs to be adjusted multiple times, affecting the installation efficiency; secondly, if the clamping of the splicing surface of the ALC board is increased, the subsequent presence of this clamping part will cause inconvenience in assembly, and at the same time will increase the construction space to a certain extent. Especially when the ALC board is assembled with a vertical wall, due to the presence of the clamping part, the ALC board cannot be well placed at the designated position. Summary of the Invention

Detailed implementation manners

[0021] The following will describe in detail various exemplary embodiments, features and aspects of the present application with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0022] The special term "exemplary" here means "serving as an example, an embodiment or illustrative". Any embodiment described as "exemplary" here does not have to be construed as superior or better than other embodiments.

[0023] In addition, for better explaining the present application, numerous specific details are given in the following detailed embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means and elements well - known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0024] In the present invention, grooves and splicing protrusions are respectively formed on both sides of the ALC board. When installing the ALC board, the grooves and splicing protrusions on two adjacent ALC boards are inserted together to achieve assembly. When connecting the ALC board to the wall, grooves or splicing protrusions can be pre - processed on the wall.

[0025] Definition: Before the ALC board is clamped and conveyed, the surface of the ALC board with grooves or the surface of the splicing protrusion is facing upward. At this time, the placement state of the ALC board is the horizontal placement state (the same hereinafter). When the length direction of the ALC board is vertically placed, the placement state of the ALC board is the vertical placement state (the same hereinafter).

[0026] Please refer to Figure 1 、Figure 2 , Figure 9 - Figure Figure 16 , in an embodiment of the present invention, a multi-functional lifting and positioning device for installing ALC plates includes a moving vehicle body 1, a multi-stage lifting mechanism 2 installed on the moving vehicle body 1 and capable of changing the placement angle relative to the moving vehicle body 1, a clamping mechanism 4, and a rotation control mechanism 5 installed on the multi-stage lifting mechanism 2 and used to drive the clamping mechanism 4 to rotate. Among them, at least two angle adjustment hydraulic cylinders 3 installed on the moving vehicle body 1 are connected to the multi-stage lifting mechanism 2.

[0027] The clamping mechanism 4 includes a mounting plate 401 and a clamping plate 402 fixed to the mounting plate 401. A driving gap is formed between the mounting plate 401 and the clamping plate 402. At least two clamping units and at least two auxiliary clamping members 404 are hinged on the clamping plate 402. The ALC plate is placed between the clamping plate 402, the clamping units, and the auxiliary clamping members 404, and the clamping units and the auxiliary clamping members 404 are arranged opposite to each other; the auxiliary clamping member 404 includes a telescopic auxiliary claw connected to the clamping plate 402 and driven to rotate by a telescopic driving member (preferably a second hydraulic cylinder 4041) installed on the clamping plate 402. An elastic telescopic member is installed on the telescopic auxiliary claw, and one end of the elastic telescopic member extends into a guiding groove 4011 formed on the mounting plate 401 and moves along the guiding groove, so that when the telescopic auxiliary claw starts to rotate from a horizontal placement state, the telescopic auxiliary claw is driven to perform rotation and shortening actions in sequence.

[0028] The clamping mechanism 4 is used to clamp the ALC plate to be installed. According to the installation angle required for the ALC plate (in construction, the ALC plate is generally in two states: horizontal placement or vertical placement), the rotation control mechanism 5 is used to adjust the placement angle of the clamping mechanism 4, so as to change the placement angle of the ALC. The multi-stage lifting mechanism 2 is used to adjust the installation height of the ALC plate to meet different installation requirements.

[0029] Among them, when clamping the ALC board, first pre-clamp the ALC board by cooperating the clamping unit with the clamping plate 402. Subsequently, control the telescopic driving member to drive the telescopic auxiliary claw to rotate towards the ALC board, push the ALC board upward, and then the clamping unit clamps tightly, so that the ALC board is kept in a horizontal state under the action of at least two telescopic auxiliary claws, realizing effective alignment after the final clamping of the ALC board. At the same time, the telescopic auxiliary claws always keep the limiting state of the ALC board during the transportation process of the ALC board, ensuring that the ALC board will not tilt due to reasons such as moving and shaking or center of gravity offset during the transportation process of the ALC board, ensuring that the ALC board is kept vertical or horizontal during installation, and facilitating subsequent positioning and docking; Secondly, when the ALC board is transported to the position where it needs to be installed and kept in the placement state to be installed (horizontal or vertical), the clamping unit and the clamping plate 402 keep the clamping state of the ALC board. Subsequently, the telescopic auxiliary claws first rotate relative to the clamping plate 402, so that the telescopic auxiliary claws no longer contact the ALC board. After the telescopic auxiliary claws rotate a certain angle, they shorten, so that the side of the ALC board close to the telescopic auxiliary claws is completely exposed, ensuring that there will be no interference due to the existence of the telescopic auxiliary claws when the ALC board is docked with the previous ALC board. At the same time, after the telescopic auxiliary claws retract, they sink into the driving gap, making the splicing side of the ALC board unobstructed. Even when the ALC board is docked with a vertical wall, the ALC board can be abutted against the wall.

[0030] In this embodiment, through the cooperation of the provided telescopic auxiliary claws with the elastic telescopic member and the guiding groove 4011, the automatic telescopic movement of the telescopic auxiliary claws is realized. During the process of grasping the ALC board, the automatic alignment of the ALC board can be realized, and multi-directional clamping of the ALC board can be achieved, ensuring that there will be no offset phenomenon during the transportation process of the ALC board or during the process of adjusting the placement angle, facilitating the subsequent docking and installation of the ALC board. Secondly, before the ALC board is docked, the telescopic auxiliary claws first rotate and then retract, which can eliminate the phenomenon of friction between the telescopic auxiliary claws and the splicing side of the ALC board, and at the same time can make the splicing side of the ALC board unobstructed, facilitating quick positioning and docking in different splicing requirements.

[0031] Please refer to Figures 12 - 14 , the telescopic auxiliary claw includes a rotating bearing member 4042 embedded in the embedded groove formed on the clamping plate 402. The movable end of the second hydraulic cylinder 4041 hinged on the driving gap side of the clamping plate 402 is hinged to the rotating bearing member 4042. The rotating bearing member 4042 extends into the driving gap and is rotatably connected to the clamping plate 402; an auxiliary claw 4043 inserted into the rotating bearing member 4042 and capable of sliding along the rotating bearing member 4042 close to or away from the ALC board side, and the auxiliary claw 4043 is connected to the elastic telescopic member.

[0032] Among them, it should be supplemented that a U-shaped groove is formed on one side of the rotating bearing member 4042, and a limiting plate 40422 is formed on the other side close to the mounting plate 401. The auxiliary claw 4043 is inserted into the U-shaped groove. Specifically, two second slide rails 40421 are symmetrically formed on the inner wall of the U-shaped groove. Sliding grooves 40431 that are slidably connected to the second slide rails 40421 are formed on both sides of the auxiliary claw 4043. When the auxiliary claw 4043 is in a horizontally placed state, the length directions of the second slide rails 40421 and the sliding grooves 40431 are both in the horizontal direction. Therefore, when the auxiliary claw 4043 acts on the ALC board in a horizontally placed state, it only receives a vertically downward force. The cooperation of the second slide rails 40421 and the sliding grooves 40431 also provides a vertical supporting force for the auxiliary claw 4043, so that the auxiliary claw 4043 will not be displaced due to the elastic telescopic member being squeezed during the clamping process, ensuring the stability during the clamping process.

[0033] Please refer to Figures 12 - 16 , the elastic telescopic member includes a connecting column 4044 fixed to the auxiliary claw 4043. The connecting column 4044 slidably penetrates through the limiting plate 40422 provided on the rotating bearing member 4042. A rolling member that is in rolling cooperation with the guiding groove 4011 is installed at one end of the connecting column 4044 facing the mounting plate 401; a spring 4045 is also sleeved on the connecting column 4044, and both ends of the spring 4045 are respectively in contact with the limiting plate 40422 and the rolling member.

[0034] The above-mentioned rolling member includes a roller seat fixedly connected to the connecting column 4044 and a roller 4046 rotatably installed on the roller seat. One end of the spring 4045 is in contact with the limiting plate 40422, and the other end is in contact with the roller seat at a position away from the roller 4046.

[0035] An arc-shaped protrusion 40111 is formed on the side of the guiding groove 4011 close to the end of the auxiliary claw 4043 facing the clamping plate 402. When the auxiliary claw 4043 is in a clamping state, the rolling member abuts against the middle position of the arc-shaped protrusion 40111; the center of the arc surface on the arc-shaped protrusion 40111 is on the rotation axis of the rotating bearing member 4042.

[0036] In this embodiment, when the auxiliary claw 4043 is in close contact with the ALC board and the ALC board is placed in a horizontal position, the axis of the connecting column 4044 will remain horizontal. At this time, the roller 4046 will be inside the guiding groove 4011 and in close contact with the central part of the arc-shaped protrusion 40111. Through the precise control of the second hydraulic cylinder 4041, the rotation of the rotating bearing 4042 can be achieved. When the rotating bearing 4042 starts to rotate, it will drive the auxiliary claw 4043, the connecting column 4044, and the roller 4046 to rotate as a whole. Before the roller 4046 moves away from the arc-shaped protrusion 40111, there will be no relative displacement between the auxiliary claw 4043 and the rotating bearing 4042, effectively avoiding the wear of the groove end face or splicing protrusion of the ALC board due to relative displacement when the auxiliary claw 4043 is still in contact with the ALC board, and preventing the appearance of gaps (worn areas) when adjacent two ALC boards are spliced due to wear, thus ensuring the tightness of the splicing and the stability of the overall structure.

[0037] Further, please refer to Figures 9 - 11 , the clamping unit includes a claw 403 arranged in an L-shaped structure and hinged to the clamping plate 402, and the claw 403 is driven to rotate by a third hydraulic cylinder 406 that is located within the driving gap and connected to the clamping plate 402.

[0038] By driving the claw 403 to rotate through the provided third hydraulic cylinder 406, the ALC board is clamped in cooperation with the clamping plate 402.

[0039] In another embodiment, the above-mentioned claw 403 arranged in an L-shaped structure can be set into two sections. For the convenience of description, the two sections of the claw 403 are defined as section C and section E respectively. Section C and section E are perpendicular to each other, and section E is hinged to the clamping plate 402. Section C and section E can be set in a hinged state, and section C is driven to rotate by a cylinder or an electric telescopic rod installed on section E, thereby realizing the clamping operation.

[0040] Please refer to Figure 7 and Figure 8 , the rotation control mechanism 5 includes a sliding bearing frame 501, a motor 504 installed on the sliding bearing frame 501, and a reducer connected to the rotating shaft of the motor 504. The output shaft of the reducer is fixedly connected to the mounting plate 401; it also includes a rectifying locking member for locking the position of the output shaft of the reducer relative to the sliding bearing frame 501.

[0041] By driving the mounting plate 401 to rotate through the provided motor 504 in cooperation with the reducer, the whole (including but not limited to the clamping plate, the claw 403, etc.) installed on the mounting plate 401 is driven to rotate to adjust the placement angle of the ALC board.

[0042] Exemplarily, in one implementation, please refer to Figure 7 、 Figure 8 and Figure 17 , the alignment locking member includes a locking member 4013 fixed to the output shaft of the speed reducer, and four card slots 40131 are formed on the locking member 4013; a cylinder 507 connecting the sliding bearing bracket 501, and a pressing wheel 506 for engaging with the card slot 40131 is installed on the movable rod of the cylinder 507.

[0043] Before the motor 504 drives the output shaft of the speed reducer to rotate, the cylinder 507 drives the pressing wheel 506 to disengage from the card slot 40131, so that the output shaft of the speed reducer loses the limiting force, and then the speed reducer can drive the mounting plate 401 to rotate. When the mounting plate 401 rotates to the required angle, the cylinder 507 extends to drive the pressing wheel 506 to snap into the corresponding card slot 40131, thereby repositioning the output shaft of the speed reducer to reduce the self-locking load of the motor 504 and reduce the risk of damage to the output shaft of the speed reducer and the rotating shaft of the motor 504.

[0044] In addition, the design of the alignment locking member also facilitates the operator to quickly adjust and lock the angle, improving the work efficiency. When the placement angle of the ALC board needs to be adjusted, the operator only needs to simply control the action of the cylinder 507 to easily unlock and reposition the output shaft of the speed reducer.

[0045] Furthermore, inclined guide surfaces are formed on both sides of the card slot 40131 on the locking member 4013 and are inclined towards the inside of the card slot 40131. When the motor 504 fails to drive the mounting plate 401 to reach the required position through the speed reducer or there is a certain angular deviation of the mounting plate 401, when the cylinder 507 extends and drives the pressing wheel 506 to move towards the locking member 4013 and abuts against the inclined guide surface, when the cylinder 507 continues to extend, it can drive the mounting plate 401 to be aligned to the predetermined position, ensuring the precise positioning of the mounting plate 401, effectively avoiding installation problems caused by angular deviation. The setting of the inclined guide surface enables the pressing wheel 506 to smoothly guide the mounting plate 401 to the correct position when contacting and snap into the card slot 40131, simplifies the operation process, improves the overall work efficiency. At the same time, this automatic alignment function also reduces the manual adjustment steps, reduces the operation difficulty, and makes the whole device easier to use and maintain.

[0046] It should be noted that a second connecting ring 505 is fixed to one side of the sliding bearing frame 501 facing the mounting plate 401, and a first connecting ring 4012 is fixed to one side of the mounting plate 401 facing the sliding bearing frame 501. The second connecting ring 505 can be inserted into the inner side of the first connecting ring 4012 and slidably abutted against the first connecting ring 4012. The provided first connecting ring 4012 and second connecting ring 505 can provide a certain supporting force for the mounting plate 401, reduce the bearing capacity of the output shaft of the reducer and the rotating shaft of the motor 504, thereby extending the service life of the reducer and the motor 504. At the same time, the sliding abutment of the first connecting ring 4012 and the second connecting ring 505 makes the mounting plate 401 move more smoothly during the movement, reduces the shaking, and further improves the stability and precision of the equipment.

[0047] Further, please refer to Figures 3 - 6 , the multi-stage lifting mechanism 2 includes a first vertical frame 201 and a second vertical frame 203 connecting the moving vehicle body 1. The first hydraulic cylinder 202 installed on the first vertical frame 201 is used to control the position adjustment of the second vertical frame 203 relative to the first vertical frame 201; the sliding bearing frame 501 is slidably installed on the second vertical frame 203 and connected to the traction member installed on the second vertical frame 203.

[0048] Specifically, a first slide rail 206 is provided on the second vertical frame 203, and a slide frame 502 slidably connected to the first slide rail 206 is provided on the sliding bearing frame 501, so that the sliding bearing frame 501 can slide smoothly along the first slide rail 206. The design of the slide frame 502 enhances the structural stability and ensures smooth and precise control during the lifting process.

[0049] By controlling the telescopic movement of the first hydraulic cylinder 202 to adjust the lifting of the second vertical frame 203 relative to the first vertical frame 201, the height of the ALC board can be changed according to different installation requirements to achieve flexible installation operations. Under the action of the first hydraulic cylinder 202, the second vertical frame 203 can rise or fall smoothly and precisely, ensuring the stability and accuracy of the ALC board during the installation process.

[0050] Exemplarily, in one implementation manner, the traction member includes at least two traction wheels 204 installed on the second vertical frame 203 and driven to rotate by a driving source. A traction rope 205 is wound around the traction wheels 204. One end of the traction rope 205 away from the traction wheels 204 is fixedly connected to a hanging ring 503 fixed on the sliding bearing frame 501. By rotating the provided traction wheels 204 to wind or unwind the traction rope 205, the lifting control of the sliding bearing frame 501 is realized.

[0051] As another embodiment of the present invention, a method for using a multi-functional lifting and positioning device for ALC board installation as described above is also proposed, including the following steps: S1. The moving vehicle body 1 moves to the ALC board placement position, and the multi-stage lifting mechanism 2 drives the clamping mechanism 4 to move to the clamping position; S2. Control the clamping unit to cooperate with the clamping plate 402 to clamp the ALC board, and then control the telescopic driving member to drive the telescopic auxiliary claw to push and clamp from the bottom of the ALC board, so as to keep the ALC board in a horizontally placed state; S3. According to the installation requirements, control the rotation control mechanism 5 to drive the ALC board and the clamping mechanism 4 as a whole to rotate to a vertically placed state, and then the moving vehicle body 1 drives the ALC board to move to the position where docking is required; S4. Control the telescopic driving member to drive the telescopic auxiliary claw to move. The telescopic auxiliary claw first rotates relative to the clamping plate 402, so that after the telescopic auxiliary claw is separated from the ALC board, it shortens to completely expose the side of the ALC board facing the telescopic auxiliary claw, and then docks with the wall or the previous ALC board to complete the positioning installation.
