Description

Technical Field

[0001] The present invention relates to the technical field of construction hoisting equipment, and particularly relates to a partition board hoisting and installing device and a hoisting method thereof. Background Art

[0002] With the strong promotion of building industrialization at the national level, various lightweight partition boards are widely used in housing construction projects, and their weight is generally 75 - 150 kg per piece. During the construction process, due to their size and weight, the installation is time-consuming and laborious, and there are also significant safety hazards during individual operations. Each construction enterprise has developed various different installation tools. For example, "a kind of autoclaved aerated concrete strip board installation equipment" with the publication number CN118145549A mainly focuses on the design of installation and attitude adjustment, and does not involve the hoisting link. Another example is "a kind of lightweight partition board installation device" with the authorization publication number CN118774418B, which effectively solves the problems of inclination, unevenness, and laborious installation of partition board installation through the design of an attitude adjustment mechanism, an active positioning mechanism, a flexible clamping mechanism, and a propulsion installation mechanism, and can install multiple pieces at a time. However, this device is relatively large in size and is not very suitable for some residential projects.

[0003] The above-listed technologies have significant advantages and certain applicability. Combining relevant engineering experience, the deficiencies in the hoisting and installation construction of partition boards mainly focus on two aspects: First, due to the size and weight of the partition boards, the installation is time-consuming and laborious, and there are safety hazards. Some tool developments do not pay attention to the hoisting operation but only focus on the installation, putting the cart before the horse. Second, the tools developed by the existing technologies are relatively large in size and have some unnecessary functions, such as means for detecting and positioning to ensure the installation quality, which increases the volume and operation complexity of the installation tools, and is not conducive to the use of workers in an environment with limited space and the frequent relocation of the tools. Summary of the Invention

[0004] In view of the above deficiencies of the prior art, the present invention provides a partition board hoisting and installing device and a hoisting method thereof, which solve the technical problems mentioned in the above background art.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows: In a first aspect, a lifting and installation device for partition boards is provided, which includes a moving seat, on which a support system and a lifting system are arranged; the support system includes a column formed by sequentially splicing a number of rectangular tubes in the vertical direction, the lower end of the column is fixed on the moving seat, and a sleeve is slidably sleeved on the lower end of the column, a support steel plate is arranged at the bottom of the sleeve, a hydraulic telescopic cylinder is arranged between the support steel plate and the lower end of the column, a locking mechanism is arranged between the sleeve and the column, a top support and a horizontal support beam are sequentially arranged from top to bottom at the upper end of the column; the lifting system includes a winch fixed on the moving seat and a steel cable wound around the winch, the winch is rotationally connected with a lifting motor, fixed pulleys are arranged at both ends of the horizontal support beam, one end of the steel cable sequentially bypasses the two fixed pulleys and is connected with a hook, and a stopping mechanism cooperating with the steel cable is also arranged on the moving seat.

[0006] The beneficial effects of adopting the above technical solution are as follows: Through the extension of the hydraulic telescopic cylinder in this solution, the top support and the support steel plate at the upper and lower ends of the column can be respectively tightened against the upper and lower floor slabs, so as to realize the limit fixation of the column, and further enable the horizontal support beam on the column to provide a reliable support for the steel cable, so as to facilitate the subsequent smooth lifting of the partition board by the cooperation of the steel cable, the hook and the lifting motor.

[0007] Further, the stopping mechanism includes a housing fixed on the moving seat and an encoder arranged on the winch, the steel cable vertically penetrates the housing, two eccentric wheels are arranged in the housing on both sides of the steel cable, and the two eccentric wheels are respectively and synchronously rotated through transmission shafts with two driving gears, a transmission rod is movably arranged between the two driving gears, racks respectively meshing with the two driving gears are arranged on both sides of the transmission rod, an electric telescopic cylinder is arranged in the housing, the end of the transmission rod is connected with the movable end of the electric telescopic cylinder, and the extending direction of the transmission rod is parallel to the telescopic direction of the electric telescopic cylinder, and the encoder and the electric telescopic cylinder are both electrically connected with a controller.

[0008] The beneficial effects of adopting the above technical solution are as follows: The stopping mechanism in this solution is a safety auxiliary device during the lifting process of the partition board. When the lifting motor fails and loses traction, the winch will instantly increase the rotation speed under the action of the pulling force of the steel cable. At this time, the encoder detects the abnormal rotation speed, drives the electric telescopic cylinder to act through the controller, and drives the transmission rod to move, so that the two driving gears rotate synchronously in the reverse direction, and further drives the two eccentric wheels to rotate synchronously in the reverse direction, so that the two eccentric wheels gradually clamp and lock the steel cable, effectively preventing the partition board from falling during lifting.

[0009] Further, an annular groove cooperating with the steel cable is arranged on the outer side wall of the eccentric wheel; the annular groove can realize the limit of the steel cable and avoid the deviation of the steel cable.

[0010] Further, the locking mechanism includes a first strip plate and a second strip plate. The upper end of the first strip plate is vertically hinged to the outer side wall of the column, and the second strip plate is vertically arranged on the outer side wall of the sleeve. A first serrated surface is arranged in the extending direction of the first strip plate, and a second serrated surface meshing with the first serrated surface is arranged in the extending direction of the second strip plate. The engaged first serrated surface and second serrated surface are locked in a one-way dislocation manner.

[0011] Further, several serrations on the first serrated surface are arranged obliquely downward, and several serrations on the second serrated surface are arranged obliquely upward.

[0012] The beneficial effects of adopting the above technical solution are as follows: The locking mechanism of this solution can provide auxiliary support for the hydraulic telescopic cylinder. When the hydraulic telescopic cylinder extends downward, at this time, the first serrated surface and the second serrated surface slide in a dislocation manner. After that, when the hydraulic telescopic cylinder is in a loaded state, due to the action of pressure, the first serrated surface and the second serrated surface can be firmly meshed together, thereby providing reliable support between the column and the sleeve, and effectively preventing the hydraulic telescopic cylinder from falling back due to excessive load.

[0013] Further, a rebound mechanism is arranged between the sleeve and the column. The rebound mechanism includes an ear plate, a tension spring and an adjusting bolt. The ear plate is arranged on the outer side wall of the column. One end of the tension spring is fixedly connected to the sleeve, and the other end of the tension spring is fixedly connected to one end of the adjusting bolt. A threaded hole is arranged on the ear plate, and the adjusting bolt is in threaded cooperation with the threaded hole.

[0014] The beneficial effects of adopting the above technical solution are as follows: The tension spring can provide assistance for the upward recovery of the sleeve, and at the same time, the adjusting bolt can adjust the stretching length of the tension spring, so as to adjust the tension of the tension spring.

[0015] Further, the ends of adjacent two rectangular tubes are in socket joint and locked by an auxiliary bolt passing through the two rectangular tubes at the same time; the top support member is a cross-shaped rectangular tube, and an installation vertical tube is arranged at the bottom of the center of the cross-shaped rectangular tube. The installation vertical tube is in socket joint with the upper end of the column and locked by an auxiliary bolt passing through the installation vertical tube and the column.

[0016] The beneficial effects of adopting the above technical solution are as follows: In this solution, several rectangular tubes adopt a splicing method of socket joint at the ends and locked by auxiliary bolts, which is convenient to operate, and the spliced column is stable and reliable; the top support member adopts a cross-shaped rectangular tube and is tightly pressed against the floor slab, which can effectively prevent the column from shifting.

[0017] Further, a support plate is arranged on the outer edge of the upper end of the column. The middle part of the horizontal support beam is movably sleeved on the installation vertical tube, and the bottom of the horizontal support beam abuts against the support plate; so that the load of the horizontal support beam can be directly transmitted to the column.

[0018] Further, a number of self-locking universal wheels are provided at the bottom of the moving seat, and a moving armrest is provided on one side of the moving seat; so as to facilitate the displacement of the moving seat.

[0019] In a second aspect, a lifting method for a partition board lifting and installation device is provided, which includes the following steps: S1: Move the moving seat to the construction position, splice columns with a number of square tubes, and install a top support and a horizontal support beam at the upper end of the columns; S2: Adjust the height of the columns until the distance between the top support and the bottom of the floor slab above it is between 15 - 30 cm; S3: Drive the hydraulic telescopic cylinder to pressurize and extend until the moving seat is suspended, and the top support and the support steel plate are respectively tightened against the upper and lower floor slabs; S4: Bind the partition board with a sling, connect the sling to the hook, and then lift the partition board by the lifting motor.

[0026] The specific embodiments of the present invention will be described below to facilitate those skilled in the art of this technology to understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art of this technology, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions made using the concept of the present invention are within the scope of protection.

[0027] Embodiment 1 As Figures 1 to 5 shown, the partition board hoisting and installing device of this solution includes a moving seat 1. A number of universal wheels 31 with self-locking are arranged at the bottom of the moving seat 1, and a moving handrail 32 is arranged on one side of the moving seat 1; to facilitate the displacement of the moving seat 1; a support system and a lifting system are arranged on the moving seat 1; the support system includes a column 2 formed by sequentially splicing a number of rectangular tubes 3 in the vertical direction. The lower end of the column 2 is fixed on the moving seat 1, and a sleeve 4 is slidably sleeved on the lower end of the column 2. A support steel plate 5 is arranged at the bottom of the sleeve 4, and a hydraulic telescopic cylinder 6 is arranged between the support steel plate 5 and the lower end of the column 2. A top support 7 and a horizontal support beam 8 are sequentially arranged at the upper end of the column 2 from top to bottom; the lifting system includes a winch 9 fixed on the moving seat 1 and a steel cable 10 wound around the winch 9. The winch 9 is rotationally connected to a lifting motor. Fixed pulleys 11 are arranged at both ends of the horizontal support beam 8. One end of the steel cable 10 sequentially bypasses the two fixed pulleys 11 and is connected to a hook 12.

[0028] In this solution, through the extension of the hydraulic telescopic cylinder 6, the top support 7 and the support steel plate 5 at the upper and lower ends of the column 2 can be respectively tightened against the upper and lower floor slabs, so as to realize the limit fixation of the column 2. Furthermore, the horizontal support beam 8 on the column 2 provides a reliable support for the steel cable 10, so as to facilitate the subsequent smooth hoisting of the partition board by the cooperation of the steel cable 10, the hook 12 and the lifting motor.

[0029] During the design, a rebound mechanism is arranged between the sleeve 4 and the column 2. The rebound mechanism includes an ear plate 25, a tension spring 26 and an adjusting bolt 27. The ear plate 25 is arranged on the outer side wall of the column 2. One end of the tension spring 26 is fixedly connected to the sleeve 4, and the other end of the tension spring 26 is fixedly connected to one end of the adjusting bolt 27. A threaded hole is arranged on the ear plate 25, and the adjusting bolt 27 is in threaded cooperation with the threaded hole; the tension spring 26 can provide assistance for the upward recovery of the sleeve 4, and at the same time, the adjusting bolt 27 can adjust the stretching length of the tension spring 26, so as to facilitate the adjustment of the tension of the tension spring 26.

[0030] The ends of adjacent rectangular tubes 3 are inserted and fitted with each other and locked by auxiliary bolts 28 that penetrate through the two rectangular tubes 3 at the same time. This splicing method is convenient to operate, and the spliced column 2 is stable and reliable; the top support 7 is a cross-shaped rectangular tube 3, and an installation vertical tube 29 is arranged at the bottom of the center of the cross-shaped rectangular tube 3. The installation vertical tube 29 is inserted and fitted with the upper end of the column 2 and locked by an auxiliary bolt 28 that penetrates through the installation vertical tube 29 and the column 2. When the cross-shaped rectangular tube 3 is pressed tightly against the floor slab, the column 2 can be effectively prevented from shifting; a support plate 30 is arranged on the outer edge of the upper end of the column 2, the middle part of the horizontal support beam 8 is movably sleeved on the installation vertical tube 29, and the bottom of the horizontal support beam 8 abuts against the support plate 30, so that the load of the horizontal support beam 8 can be directly transmitted to the column 2.

[0031] Embodiment 2 As Figures 1 to 3 shown, this embodiment is a further limitation based on Embodiment 1. A stop mechanism cooperating with the steel cable 10 is arranged on the moving seat 1. The stop mechanism includes a housing 13 fixed on the moving seat 1 and an encoder 14 arranged on the winch 9. The encoder 14 can detect the rotation direction and rotation speed of the winch 9; the steel cable 10 vertically penetrates through the housing 13, and two eccentric wheels 15 are arranged in the housing 13 on both sides of the steel cable 10. An annular groove cooperating with the steel cable 10 is arranged on the outer side wall of the eccentric wheel 15; the annular groove can limit the steel cable 10 to prevent the steel cable 10 from shifting. At the same time, the steel cable 10 can slide up and down in the gap space formed by the annular grooves of the two eccentric wheels 15; the two eccentric wheels 15 are respectively and synchronously rotationally connected with two driving gears 17 through a transmission shaft 16. The transmission shaft 16 is limited on the installation vertical plate 33 in the middle of the housing 13. A transmission rod 18 is movably arranged between the two driving gears 17, and racks 19 respectively meshing with the two driving gears 17 are arranged on both sides of the transmission rod 18. An electric telescopic cylinder 20 is arranged in the housing 13. The lower end of the transmission rod 18 is connected with the movable end of the electric telescopic cylinder 20, and the extending direction of the transmission rod 18 is parallel to the telescopic direction of the electric telescopic cylinder 20. The encoder 14 and the electric telescopic cylinder 20 are both electrically connected to the controller for convenient linkage control.

[0032] The stop mechanism of this solution serves as a safety auxiliary device during the hoisting process of partition boards. When the lifting motor fails and loses traction, the winch 9 will instantaneously increase its rotational speed under the tensile force of the steel cable 10. At this time, the encoder 14 detects abnormal rotational speed and sends a signal to the controller. The controller drives the electric telescopic cylinder 20 to act and drives the transmission rod 18 to move, so that the two driving gears 17 rotate synchronously in opposite directions, and then drives the two eccentric wheels 15 to rotate synchronously in opposite directions, causing the clearance space formed by the annular grooves of the two eccentric wheels 15 to gradually shrink, so that the two eccentric wheels 15 gradually clamp and lock the steel cable 10, effectively preventing the partition board from falling during hoisting; at the same time, the frictional force generated by the steel cable 10 on the two eccentric wheels 15 drives the two eccentric wheels 15 to rotate in the same direction as the electric telescopic cylinder 20 drives the two eccentric wheels 15. The load required by the electric telescopic cylinder 20 is relatively low, and the stopping effect of the steel cable 10 gradually increases with the rotation of the two eccentric wheels 15 until the steel cable 10 is locked.

[0033] Embodiment 3 As Figure 4 and Figure 5 shown, this embodiment is a further limitation based on Embodiment 1. There are two locking mechanisms provided between the sleeve 4 and the column 2. The two locking mechanisms are respectively located on both sides of the sleeve 4 and the column 2. The locking mechanism includes a first strip plate 21 and a second strip plate 22. The upper end of the first strip plate 21 is vertically hinged on the outer side wall of the column 2, and the second strip plate 22 is vertically arranged on the outer side wall of the sleeve 4. A first serrated surface 23 is provided in the extending direction of the first strip plate 21, and a second serrated surface 24 meshing with the first serrated surface 23 is provided in the extending direction of the second strip plate 22. A number of serrations on the first serrated surface 23 are inclined downward, and a number of serrations on the second serrated surface 24 are inclined upward, so that the meshing first serrated surface 23 and the second serrated surface 24 are locked with one-way dislocation.

[0034] The locking mechanism of this solution can provide auxiliary support for the hydraulic telescopic cylinder 6. When the hydraulic telescopic cylinder 6 extends downward, the second serrated surface 24 on the second strip plate 22 slides downward relative to the first serrated surface 23 on the first strip plate 21. At this time, the first serrated surface 23 and the second serrated surface 24 can automatically slide with dislocation and will not be locked; then the hydraulic telescopic cylinder 6 is in a loaded state. Due to the action of pressure, the first serrated surface 23 and the second serrated surface 24 can be firmly engaged together, that is, the second serrated surface 24 will not slide upward relative to the first serrated surface 23, thereby providing reliable support between the column 2 and the sleeve 4, effectively preventing the hydraulic telescopic cylinder 6 from falling back due to excessive load, and further providing a safety support guarantee for the support of this solution.

[0035] Combining the above Embodiments 1-3, this solution provides a hoisting method for a partition board hoisting and installation device, which includes the following steps: S1: Move the moving seat 1 to the construction position, splice the upright column 2 with a number of square tubes 3, and install a cross-shaped square tube 3 and a horizontal support beam 8 at the upper end of the upright column 2; specifically, the ends of two adjacent square tubes 3 are inserted and fitted with each other and locked by auxiliary bolts 28 that penetrate through the two square tubes 3 at the same time. The installation vertical tube 29 at the center of the cross-shaped square tube 3 is inserted and fitted with the upper end of the upright column 2 and locked by the auxiliary bolts 28 that penetrate through the installation vertical tube 29 and the upright column 2. The middle part of the horizontal support beam 8 is movably sleeved on the installation vertical tube 29; S2: Adjust the height of the upright column 2 until the distance between the cross-shaped square tube 3 and the bottom of the floor slab above it is between 15 - 30 cm; S3: Drive the hydraulic telescopic cylinder 6 to pressurize and extend until the moving seat 1 is suspended, and the cross-shaped square tube 3 and the support steel plate 5 are respectively tightened against the upper and lower floor slabs; at this time, the first serrated surface 23 on the first strip plate 21 and the second serrated surface 24 on the second strip plate 22 are firmly engaged together, providing reliable support between the upright column 2 and the sleeve 4; S4: Bind the partition board with a sling, connect the sling with the hook 12, then lift the partition board by the lifting motor, and cooperate with manual work to horizontally install the partition board.
