In the description of the present invention, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0037] like Figure 1-Figure 6 As shown, the present invention provides a precast concrete panel installation device for installing a precast concrete panel 10. The lower part of the precast concrete panel 10 is provided with slots for inserting steel bars and lifting holes for hoisting by a crane. The precast concrete panel 10 is a prior art, and the specific structure is not repeated here. The device includes a base 20, a control cabinet and two installation mechanisms.

[0038] Casters 21 are arranged around the bottom of the base 20, and the casters 21 are universally connected to the base 20, and the casters 21 have a braking function. The front side of the base 20 is provided with an installation space extending inward and penetrating in the longitudinal direction.

[0039] The two installation mechanisms are respectively arranged on two sides of the installation space, and the installation mechanisms include a rotating assembly 30 , a lifting assembly 40 and a driving assembly 50 .

[0040] The rotating assembly 30 includes a vertical plate 31, a rotating plate 32, a first motor 33, a support plate 34 and a second motor 35. The vertical plate 31 is arranged in the longitudinal direction. The rotating plate 32 is arranged in the longitudinal direction and is rotatably connected to the vertical plate 31. Baffles 36 are respectively arranged on both sides of the inner side surface of the rotating plate 32, and the baffles 36 are plugged into the rotating plate 32. A clamping area 37 is formed between the two baffles 36, and the clamping area 37 is adapted to the precast concrete slab 10. The first motor 33 is fixedly mounted on the vertical plate 31 and is used to control the rotation of the rotating plate 32. The first motor 33 is electrically connected to the control cabinet. The support plate 34 is arranged on the inner side of the vertical plate 31 in the transverse direction and is rotatably connected to the rotating plate 32. The second motor 35 is fixedly mounted on the rotating plate 32 and is used to control the rotation of the support plate 34. The second motor 35 is electrically connected to the control cabinet.

[0041] The lifting assembly 40 is used to control the rotating assembly 30 to move up and down.

[0042] The driving assembly 50 is used to control the horizontal movement of the rotating assembly 30 .

[0043] In the initial state, the locking area 37 is in a horizontal state. In this device, the two installation mechanisms work synchronously. For the sake of easy understanding, the working process of only one installation mechanism is described below.

[0044] The specific working process of the installation mechanism is:

[0045] First, the construction workers stack multiple precast concrete panels 10 on the base 20 in the longitudinal direction by means of a crane or other equipment. From bottom to top, the bottoms of the multiple precast concrete panels 10 extend a distance toward the installation space in sequence to facilitate subsequent installation one by one.

[0046] Then, the construction worker controls the rotating assembly 30 to approach the precast concrete panel 10 through the driving assembly 50 and the lifting assembly 40 until the lower part of the precast concrete panel 10 passes through the locking area 37 and contacts the supporting plate 34. The construction worker controls the first motor 33 to start through the control cabinet, and the first motor 33 drives the rotating plate 32 to rotate upward 90 degrees until the precast concrete panel 10 is in an upright state.

[0047] Next, the construction worker moves the device to the vicinity of the location to be installed, and controls the rotating assembly 30 to move closer to the location to be installed through the driving assembly 50 and the lifting assembly 40 until the slots on the precast concrete slab 10 are aligned with the steel bars at the location to be installed.

[0048] Finally, the construction worker controls the rotating assembly 30 to move downward through the lifting assembly 40 until the slots on the precast concrete panel 10 match the steel bars at the position to be installed. The control cabinet controls the second motor 35 to start, and the second motor 35 drives the support plate 34 to rotate until the support plate 34 is out of contact with the precast concrete panel 10, completing the installation of the precast concrete panel 10. Then, the baffle 36 is removed, and the device is moved away to prepare for the installation of the next precast concrete panel 10.

[0049] In one embodiment, the lifting assembly 40 includes a slider 41, a guide rod 42, a lifting plate 43 and a cylinder 44. The slider 41 is disposed on the base 20. The guide rod 42 is fixedly mounted on the slider 41 in the longitudinal direction. The lifting plate 43 is disposed on the guide rod 42 and is slidably connected to the guide rod 42, and the lifting plate 43 is fixedly connected to the vertical plate 31. The cylinder 44 is tilted and electrically connected to the control cabinet, and the first end of the cylinder 44 is hinged to the slider 41, and the second end of the cylinder 44 is hinged to the lifting plate 43.

[0050] When the lifting assembly 40 is started, the control cabinet controls the cylinder 44 to start, and the cylinder 44 will be extended and retracted. Under the action of the guide rod 42, the lifting plate 43 will move the vertical plate 31 up and down, thereby controlling the entire rotating assembly 30 and the precast concrete slab 10 to move up and down. The lifting assembly 40 has a simple structure and is easy to produce and manufacture.

[0051] In one embodiment, the driving assembly 50 includes a guide rail 51, a lead screw 52, ​​and a third motor 53. The guide rail 51 is fixedly mounted on the base 20 in the transverse direction and is slidably connected to the slider 41. The lead screw 52 passes through the slider 41 in the transverse direction, and both ends are rotatably connected to the base 20, and the lead screw 52 is threadedly connected to the slider 41. The third motor 53 is fixedly mounted on the base 20 and is used to control the rotation of the lead screw 52. The third motor 53 is electrically connected to the control cabinet.

[0052] When the driving assembly 50 is started, the control cabinet controls the third motor 53 to start, and the third motor 53 drives the lead screw 52 to rotate. Under the action of the guide rail 51, the slider 41 will move horizontally, thereby controlling the horizontal movement of the entire rotating assembly 30 and the precast concrete panel 10. The driving assembly 50 has a simple structure and is easy to produce and manufacture.

[0053] In one embodiment, a receiving groove 341 is formed inside the support plate 34 , and a guide hole 342 communicating with the receiving groove 341 is formed on the top of the support plate 34 .

[0054] The mounting mechanism further includes a limiting assembly 60, which includes a movable plate 61, a limiting rod 62, a spring 63, an iron block 64, and an electromagnet 65. The movable plate 61 is arranged in the accommodating groove 341 in a transverse direction and is in sliding contact with the inner wall of the accommodating groove 341. The limiting rod 62 is arranged in the guide hole 342 and is in sliding contact with the inner wall of the guide hole 342. The limiting rod 62 is adapted to the hanging hole on the concrete slab 10, and the limiting rod 62 is fixedly connected to the movable plate 61. The first end of the spring 63 is fixedly connected to the movable plate 61, and the second end of the spring 63 is fixedly connected to the inner wall of the accommodating groove 341. The spring 63 makes the movable plate 61 have a tendency to move upward. The iron block 64 and the electromagnet 65 are arranged oppositely, the iron block 64 is fixedly connected to the movable plate 61, and the electromagnet 65 is fixedly connected to the bottom of the inner wall of the accommodating groove 341.

[0055] In the initial state, due to the action of the spring 63, the limiting rod 62 extends from the guide hole 342. When the lower part of the precast concrete slab 10 passes through the locking area 37 and contacts the support plate 34, the limiting rod 62 is just inserted into the hanging hole of the precast concrete, thereby further limiting the precast concrete slab 10, so that the two ends of the lower part of the precast concrete slab 10 are stably clamped by the two mounting mechanisms respectively.

[0056] When the construction worker controls the rotating assembly 30 to move downward through the lifting assembly 40, and the slots on the precast concrete panel 10 match the steel bars at the position to be installed, the construction worker energizes the electromagnet 65 through the control cabinet, and the electromagnet 65 adsorbs the iron block 64 after being energized, so that the movable plate 61 drives the limit rod 62 to move downward until the limit rod 62 is hidden in the support plate 34. In this way, when the second motor 35 drives the support plate 34 to rotate, the support plate 34 and the precast concrete panel 10 will be out of contact, and the precast concrete panel 10 will fall smoothly, completing the installation.

[0057] In one embodiment, a plug hole is formed at the bottom of the rotating plate 32. The limiting assembly 60 further includes an insert rod 66, a first end of which is fixedly connected to the movable plate 61, and a second end of which passes through the supporting plate 34 and extends into the plug hole.

[0058] In the initial state, the second end of the insertion rod 66 passes through the support plate 34 and extends into the insertion hole, so that there is no relative rotation between the support plate 34 and the rotating plate 32, thereby further limiting the precast concrete panel 10, so that the lower ends of the precast concrete panel 10 are stably clamped by two mounting mechanisms respectively.

[0059] When the construction workers control the rotating assembly 30 to move downward through the lifting assembly 40, and the slots on the precast concrete slab 10 match the steel bars at the installation position, the construction workers energize the electromagnet 65 through the control cabinet, and the movable plate 61 will also drive the insertion rod 66 to move downward synchronously until the insertion rod 66 is hidden in the support plate 34, which will not affect subsequent work.

[0060] In one embodiment, side panels 22 are fixedly mounted on both sides of the top of the base 20, and a limiting area is formed between the two side panels 22, in which a plurality of precast concrete panels 10 stacked in the longitudinal direction are placed. The two side panels 22 limit the plurality of precast concrete panels 10.

[0061] A mounting method, wherein two mounting mechanisms work synchronously, and the mounting mechanisms include the following working steps:

[0062] S1. The control cabinet controls the first motor 33 to start, and the first motor 33 controls the locking area 37 to be in a horizontal state.

[0063] S2 , the driving assembly 50 and the lifting assembly 40 control the rotating assembly 30 to approach the precast concrete panel 10 until the lower portion of the precast concrete panel 10 passes through the locking area 37 and contacts the supporting plate 34 .

[0064] S3. The construction worker starts the first motor 33 through the control cabinet, and the first motor 33 drives the rotating plate 32 to rotate upward by 90° until the precast concrete slab 10 is in an upright state.

[0065] S4, the construction worker moves the device to the vicinity of the location to be installed, and controls the rotating assembly 30 to move closer to the location to be installed through the driving assembly 50 and the lifting assembly 40 until the slots on the precast concrete slab 10 are aligned with the steel bars at the location to be installed.

[0066] S5. The construction worker controls the rotating assembly 30 to move downward through the lifting assembly 40 until the slots on the precast concrete slab 10 match the steel bars at the location to be installed.

[0067] S6, the control cabinet controls the second motor 35 to start, and the second motor 35 drives the support plate 34 to rotate until the support plate 34 is out of contact with the precast concrete panel 10, and the installation of the precast concrete panel 10 is completed. Then the baffle 36 is removed, and the device is removed to prepare for the next installation of the precast concrete panel 10.

[0068] In one embodiment, in step S1, the insertion rod 66 is located in the insertion hole, so that relative rotation does not occur between the support plate 34 and the rotating plate 32, thereby further limiting the precast concrete panel 10, so that the lower ends of the precast concrete panel 10 are stably clamped by two mounting mechanisms respectively.

[0069] In step S6, before the second motor 35 is started, the electromagnet 65 is energized to attract the movable plate 61 until the limit rod 62 is separated from the hanging hole on the precast concrete slab 10 and the insertion rod 66 leaves the insertion hole. After the construction worker energizes the electromagnet 65 through the control cabinet, the movable plate 61 will also drive the insertion rod 66 to move downward synchronously until the insertion rod 66 is hidden in the support plate 34, which will not affect subsequent work.

[0070] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
