It should be noted that, unless there is a conflict, the embodiments of the present disclosure and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] See also Figures 1 to 4 , which shows the preferred structure of the civil engineering construction lifting device provided by the embodiment of the present invention. As shown in the figure, the construction lifting device includes: a mobile base 1, a mounting frame 2, a lifting platform 3, and a switching support mechanism 4; wherein, The mounting frame 2 is arranged on the mobile base 1, and plays a guiding and supporting role in the lifting and lowering of the lifting platform 3. Specifically, the mobile base 1 plays an overall supporting and moving role, and can realize the overall movement of the device. The mounting frame 2 can be arranged above the mobile base 1, and the mounting frame 2 can be fixed on the top wall of the mobile base 1, and can be fixed by bolts or welding. The mounting frame 2 plays a guiding and supporting role in the lifting and lowering of the lifting platform 3. Among them, the mounting frame 2 can include two inverted U-shaped frames 21 arranged side by side and at intervals, and the two inverted U-shaped frames 21 are both arranged vertically, and the positions of the side support rods of the two inverted U-shaped frames 21 correspond to and are adapted to the four corners of the lifting and lifting platform 3.

[0020] The lifting platform 3 is arranged on the upper side of the mobile base 2, and the lifting platform 3 is arranged on the mounting frame 2 in a manner that can be adjusted in height, so as to provide a construction platform that can be raised and lowered to carry construction personnel and / or construction components and drive the construction personnel and / or construction components to adjust their height positions. Specifically, the lifting platform 3 can be parallel to the mobile base 1 and arranged above the mobile base 1, and the four corners of the lifting platform 3 are slidably connected to the four side support rods 211 of the two inverted U-shaped frames 21 to adjust the height positions of the construction personnel and / or construction components carried on the lifting platform 3, thereby being suitable for construction environments at different heights. In this embodiment, the lifting platform 3 is connected to a lifting drive mechanism 5 for driving the lifting platform 3 to adjust its position in the height direction to adjust the height position of the construction personnel and / or construction components to adapt to construction positions at different heights. Among them, the lifting drive mechanism 5 can be fixedly mounted on the mounting frame 2, and the power output end is connected to the lifting platform 3 to drive the lifting platform 3 to slide along the length direction of the side support rods 211 to achieve lifting. In this embodiment, the lifting platform 3 may be a plate-shaped structure, serving as a lifting plate, and adjusting the height position of construction personnel and / or construction components by lifting.

[0021] The switching support mechanism 4 is arranged on the mobile base 1 in a position-adjustable manner along the height direction, and is used to move away from the mobile base 1 to support the mobile base 1 so that the mobile base 1 is suspended in the air, and can move toward the mobile base 1 so that the mobile base 1 is supported and moved on the ground.

[0022] Specifically, the switching support mechanism 4 can be parallel to the mobile base 1 and disposed below the mobile base 1. Furthermore, the switching support mechanism 4 can move up and down relative to the mobile base 1 in the height direction, so that it can move away from the mobile base 1, i.e., move downward. It can press against the ground and support the mobile base 1 until the mobile base 1 is suspended in the air, thereby securing the construction lifting device through the switching support mechanism 4. This ensures the stability of the construction lifting device during construction support and prevents it from moving arbitrarily. Of course, the switching support mechanism 4 can also move toward the mobile base 1, i.e., upward, so that the mobile base 1 gradually contacts the ground and is supported by the mobile base 1, with the switching support mechanism 4 suspended in the air, and the entire construction lifting device is moved by the mobile base 1. In this embodiment, the switching support mechanism 4 is connected to a switching drive mechanism 6 for driving the switching support mechanism 4 to adjust its position in the height direction to achieve switching between supporting and suspended positions. The switching drive mechanism 6 can be fixedly mounted on the mobile base 1, with its power output connected to the switching support mechanism 4 to drive the switching support mechanism 4 to adjust its position in the height direction, i.e., to drive the switching support mechanism 4 to move up and down. In this embodiment, the switching support mechanism 4 can be a plate-like structure, which can ensure support stability through a large area. Of course, it can also be other structures, such as a strip structure. When the switching support mechanism 4 is a strip structure, it can also be multiple to ensure support stability. Moreover, each switching support mechanism 4 can be connected to a switching drive mechanism 6 to achieve synchronous lifting. Of course, when the switching support mechanism 4 is a plate-like structure, it can be connected to multiple switching drive mechanisms 6, which can respectively and synchronously drive different sides of the switching support mechanism 4.

[0023] Continue to see Figure 1 The mobile base 1 includes a base body 11 and four moving wheels 12 arranged at the four corners below the base body 11. Specifically, the base body 11 can be a rectangular base structure, and the moving wheels 12 are arranged at the four corners to achieve walking movement.

[0024] Continue to see Figures 1 to 3 The lifting drive mechanism 5 may include: a lifting drive motor 51, a transmission assembly 52 and two vertically arranged lifting transmission screws 53; wherein, the power input end of the transmission assembly 52 is connected to the power output end of the lifting drive motor 51, and the transmission assembly 52 has two power output ends that move synchronously; the two lifting transmission screws 53 are arranged at intervals, and the two lifting transmission screws 53 are respectively connected to the two power output ends of the transmission assembly 52, and the two lifting transmission screws 53 are respectively screwed to two different positions of the lifting and lifting platform 3 to form two ball screw pairs, which are used to convert the synchronous rotation of the two power output ends of the transmission assembly 52 into synchronous vertical reciprocating linear motion of two different positions of the lifting and lifting platform 3.

[0025] Specifically, the lifting drive motor 51 can be fixedly mounted on the mounting frame 2, and its power output end is connected to the power input end of the transmission assembly 52 to drive the transmission assembly 52 to move. The two lifting transmission screws 53 are rotatably arranged on the two inverted U-shaped frames 21 respectively, and their bottom ends and top ends are rotatably arranged on the horizontal support rods 212 and the movable base 1 of the inverted U-shaped frame 21 respectively. The two lifting transmission screws 53 are respectively connected to the two power output ends of the transmission assembly 52; the two lifting transmission screws 53 are respectively passed through two different positions of the lifting and lifting platform 3, and are respectively screwed to two different positions of the lifting and lifting platform 3. Of course, a lifting slider connected to the lifting transmission screw 53 can also be welded on the lifting and lifting platform 3, which can drive the two lifting transmission screws 53 to rotate synchronously through the transmission assembly 52, and the rotation of the lifting transmission screw 53 is converted into the lifting of the lifting platform 3 along the length direction of the lifting transmission screw 53 (such as Figure 1 The reciprocating linear motion in the vertical direction (as shown) realizes the lifting and lowering adjustment of the lifting platform 3. The transverse support rod 212 is hollow inside.

[0026] Continue to see Figures 2 to 3 The transmission assembly 52 includes: a driving wheel 521, a driven wheel 522, a transmission belt 523, two rotating rods 524, two driving gears 525 and two driven gears 526; wherein the driving wheel 521 and the driven wheel 522 are arranged at intervals; the transmission belt 523 is sleeved on the outer periphery of the driving wheel 521 and the driven wheel 522, and is used to rotate under the drive of the driving wheel 521 and drive the driven wheel 522 to rotate synchronously with the driving wheel 521; the two rotating rods 524 are respectively connected to the driving wheel 521 and the driven wheel 522, and are used to rotate synchronously with the driving wheel 521. The driving wheel 521 and the driven wheel 522 rotate synchronously; the two driving gears 525 are respectively provided on the two rotating rods 524; the two driven gears 526 serve as two power output ends and are respectively provided on the two lifting transmission screws 53, and the two driven gears 526 are respectively engaged with the two driving gears 525, and are used to drive the two lifting transmission screws 53 to rotate synchronously when the two driving gears 525 rotate synchronously with the two rotating rods 524, so as to drive the lifting platform 3 to perform vertical reciprocating linear motion.

[0027] Specifically, the driving wheel 521 and the driven wheel 522 are respectively arranged at the matching positions of the two transverse support rods 212. Two rotating rods 524 are rotatably arranged within the two transverse support rods 212, and are coaxially arranged and fixedly connected to the driving wheel 521 and the driven wheel 522 respectively. The two rotating rods 524 are each equipped with a driving gear 525 at the matching positions of the lifting transmission screw 53. The driving gear 525 and the rotating rods 524 are coaxially arranged and fixedly connected to each other for synchronous rotation. The two driven gears 526 are respectively mounted and fixedly connected to the two lifting transmission screws 53 and respectively mesh with the two driving gears 525 to achieve transmission. In this embodiment, the rotating rods 524 are arranged perpendicular to the lifting transmission screw 53. The driving gear 525 and the driven gear 526 are matched bevel gears that can achieve switching of rotation direction, thereby converting rotation on the horizontal axis into rotation on the vertical axis. The lifting drive motor 51 drives the driving wheel 521 to rotate, causing the transmission belt 523 to rotate, and driving the driven wheel 522 to rotate, so as to drive the two rotating rollers 524 and the two driving gears 525 arranged thereon to rotate through the driving wheel 521 and the driven wheel 522. The two driving gears 525 are engaged with the two driven gears 526, driving the two driven gears 526 to rotate, thereby enabling the two lifting transmission screws 53 to rotate at the same time. The rotation of the lifting transmission screw 53 drives the lifting platform 3 to rise and fall to adjust the height of the device so that the device can be suitable for construction environments at different heights.

[0028] In this embodiment, in order to avoid external interference in the movement of the driving wheel 521, the driven wheel 522, and the transmission belt 523, preferably, a mounting box 527 is provided on the mounting frame 2, and its cover is arranged on the outside of the driving wheel 521, the driven wheel 522, and the transmission belt 523. Specifically, a mounting box 527 is fixedly installed on one side of the mounting frame 2, and the mounting box 527 can be set between the two inverted U-shaped frames 21, and the two ends are respectively connected to the transverse support rods 212 of the two inverted U-shaped frames 21. The driving wheel 521 and the driven wheel 522 are rotatably connected to both sides of the inner wall of the mounting box 527. The driving wheel 521 and the driven wheel 522 are fixedly connected to the two rotating rods 524, and the transmission belt 523 is slidably connected to the outer wall surface of the driving wheel 521 and the driven wheel 522. The lifting drive motor 51 can be fixedly mounted on one side of the mounting box 527 (such as Figure 2 As shown on the left side, the power output end of the lifting drive motor 51 rotates and extends into the installation box 527 and is fixedly connected to the driving wheel 521.

[0029] Continue to see Figure 1 and Figure 4The switching drive mechanism 6 may include: a switching drive motor 61, a switching transmission screw 62, two transmission sliders 63, a scissors articulated lifting frame 64, and two transmission connecting blocks 65; wherein the switching transmission screw 62 is connected to the power output end of the switching drive motor 61 for rotating under the drive of the switching drive motor 61; the two transmission sliders 63 are sleeved on the switching transmission screw 62 and are both screwed to the switching transmission screw 62 for converting the rotation of the switching transmission screw 62 into the opposite movement or opposite movement of the two transmission sliders 63; the scissors articulated lifting frame 64 is connected to the switching drive motor 61; The two power input ends are respectively hinged to the two transmission sliders 63; the two transmission connection blocks 65 are respectively hinged to the two power output ends of the scissor articulated lifting frame 64. In addition, the two transmission connection blocks 65 are slidably arranged on the switching support mechanism 4 in a direction parallel to the switching transmission screw 62. When the two transmission sliders 63 move toward or away from each other, the two transmission connection blocks 65 move synchronously toward or away from each other, and the scissor articulated lifting frame 64 pushes or pulls the switching support mechanism 4 to move vertically, away from or toward the movable base 1. To improve the stability of the sliding of the transmission slider 63, a fixed slide bar 66 is also provided on one side of the switching transmission screw 62. It is fixedly mounted on the movable base 1 and guides the sliding of the transmission slider 63.

[0030] Specifically, the switching transmission screws 62 are rotatably connected on both sides of the inner wall of the mobile base 1, wherein the switching transmission screws 62 can be bidirectional threaded rods, and fixed slide bars 66 are fixedly installed on both sides of the inner wall of the mobile base 1. The surface of the bidirectional threaded rod 62 is threadedly connected to two transmission sliders 63, and the two transmission sliders 63 are slidably connected to the surface of the fixed slide bar 66. A switching drive motor 61 is fixedly installed on one side of the mobile base 1, and the output shaft of the switching drive motor 61 is fixedly connected to the switching transmission screw 62. The inner wall surfaces of the two transmission sliders 63 are rotatably connected to the scissors articulated lifting frame 64, and two transmission connection blocks 65 are rotatably connected to one side of the scissors articulated lifting frame 64 (such as Figure 4 As shown in the lower side, by starting the switching drive motor 61, the switching drive motor 61 drives the switching transmission screw 62 to rotate, so that the two switching transmission screws 62 move toward each other. The two switching transmission screws 62 move toward each other and drive the scissors hinged lifting frame 64 to open, pushing the two transmission connection blocks 65 to move toward each other, and at the same time causing the switching support mechanism 4 to descend to support the device.

[0031] Continue to see Figure 4The scissor articulated lifting frame 64 comprises two hinged lifting connecting rods. Specifically, the two lifting connecting rods are arranged crosswise in the middle, with their ends hinged to the transmission sliders 63 and transmission connecting blocks 65 on opposite sides. When the two upper transmission sliders 63 move toward each other, they drive the top ends of the two lifting connecting rods to move toward each other, gradually reducing the angle between the two lifting connecting rods, i.e., opening them. This in turn causes the two lower transmission connecting blocks 65 to move toward each other synchronously, thereby driving the switching support mechanism 4 to descend.

[0032] The working principle of the device: When the device is used, the device should be moved to a suitable position first, and then the switching drive motor 61 is started. The switching drive motor 61 drives the switching transmission screw 62 to rotate, so that the two switching transmission screws 62 move toward each other. The two switching transmission screws 62 move toward each other and drive the scissors hinged lifting frame 64 to open, pushing the two transmission connecting blocks 65 to move toward each other, and at the same time causing the switching support mechanism 4 to descend to support the device. Afterwards, the construction worker stands on the lifting platform 3 and starts the lifting drive motor 51. The lifting drive motor 51 drives the driving wheel 521 to rotate, so that the transmission belt 523 rotates and drives the driven wheel 522 to rotate, so as to drive the two rotating rollers 524 and the two driving gears 525 arranged thereon to rotate through the driving wheel 521 and the driven wheel 522. The two driving gears 525 are engaged with the two driven gears 526, driving the two driven gears 526 to rotate, thereby enabling the two lifting transmission screws 53 to rotate at the same time. The rotation of the lifting transmission screw 53 drives the lifting platform 3 to rise and fall to adjust the height of the device so that the device can be suitable for construction environments at different heights.

[0033] In summary, the civil engineering construction lifting device provided in this embodiment can be adjusted in height by switching the support mechanism 4. It can move away from the mobile base 1 to support the mobile base 1 so that the mobile base 1 is suspended in the air for fixed support. This solves the problem that the previous civil engineering construction support uses ground anchors to fix the device to the ground to prevent the device from moving. However, the installation of ground anchors will cause certain damage to the ground. Drilling will make the ground structure loose. After the ground anchors are pulled out, holes will be left on the ground, which may affect the flatness and subsequent use of the ground and may also cause ground subsidence and water accumulation. This achieves the beneficial effect of supporting the device while avoiding damaging the ground. Of course, the switching support mechanism 4 can also move toward the mobile base 1 to support the mobile base 1 on the ground for movement. In addition, the device can be adjusted in height by lifting the lifting platform 3, providing a construction platform that can be raised and lowered to carry construction personnel and / or construction components and drive the construction personnel and / or construction components to adjust their height position. This achieves the beneficial effect of being able to adjust the height of the device so that the device can be applied to construction scenes of different heights to improve the applicability of the device.
