[0014] A method for using a quick-install scaffold for construction comprises the following steps: S1. First, install the bottom sleeve, the middle sleeve and the top sleeve on the support column in sequence, and assemble them with the support middle plate, the balance bracket and the support rod, so that the lifting plate is installed on the free end of the hydraulic telescopic rod, and then install the two tilting rods crosswise on the end of the lifting plate, and then install the ends of the two cross tilting rods on the splicing shaft for easy disassembly; S2. When the scaffold is assembled, the four support columns rise with the ground bulge and fall with the ground sag by their own gravity. By observing the settings of the No. 1 and No. 2 level gauges, the balance bracket and the support middle plate are in a horizontal state. Then, the pins are respectively inserted into the corresponding sockets and through holes, so that the four bottom sliding sleeves are in a horizontal state. Therefore, the four top sliding sleeves are in a horizontal state, and the stepping platform is leveled to prevent the scaffold from tilting, which has a leveling function. S3. When the scaffolding is leveled, it is only necessary to fix the middle sliding sleeve on the supporting column by means of a latch to prevent the middle sliding sleeve from moving up and down, and the moving wheel is in a free moving state. When the free end of the hydraulic telescopic rod is extended, the inner rod drives the lifting plate upward, and the intersection of the two mutually intersecting inclined rods has an upward jacking force, so that the top sliding sleeves on the left and right sides are close to each other, and the top sliding sleeve drives the length of the treading platform to be shortened. When the free end of the hydraulic telescopic rod is retracted, similarly, the top sliding sleeves on the left and right sides are close to each other, and the top sliding sleeve drives the length of the treading platform to be extended, so that the construction range of the scaffolding can be changed according to the demand. S4. When the scaffolding is leveled, the four moving wheels are first locked to prevent the moving wheels from moving. It is only necessary to drive the lifting plate to be lifted and lowered by the free end of the hydraulic telescopic rod. The lifting plate drives the mutually crossed tilting rods to be lifted and lowered. The tilting rods drive the top sliding sleeve and the middle sliding sleeve to be lifted and lowered, and the through hole is made to correspond to any one of the sockets. After adjusting the height, the pin is inserted into the corresponding through hole and socket, thereby adjusting the height of the stepping platform. Therefore, the scaffolding has the function of adjusting the height.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention first installs the bottom sliding sleeve, the middle sliding sleeve and the top sliding sleeve on the supporting column in sequence, inserts the end of the supporting middle plate into the interior of the balancing bracket, inserts the support rod into the end of the balancing bracket, and installs the lifting plate on the top of the free end of the hydraulic telescopic rod. Then, the two tilting rods are cross-mounted on the end of the lifting plate, and then with the use of springs, the user drives the two crossed tilting rods inward by hand to compress and contract the springs. At this time, the ends of the two crossed tilting rods can be installed on the splicing shaft, and the hands are released to reset the springs to prevent the tilting rods from falling off. Therefore, the scaffolding is easy to assemble and easy to disassemble or transport.

[0016] 2. When the scaffolding of the present invention is assembled, the four mutually supporting columns rise due to their own gravity as the ground bulges and fall as the ground sags. By observing the No. 1 level meter, the balance bracket is in a horizontal state left and right, and then by observing the No. 2 level meter, the supporting middle plate is in a horizontal state front and back, and then the pins are inserted into the corresponding jacks and through holes respectively, so that the four bottom sliding sleeves are in a horizontal state, and the four supporting columns are in a vertical state. Therefore, the four top sliding sleeves are in a horizontal state, and the stepping platform is leveled to prevent the scaffolding from tilting, and it has a leveling function.

[0017] 3. When the scaffolding is leveled, the middle sleeve only needs to be fixed on the supporting column by a latch to prevent the middle sleeve from moving up and down, and the moving wheel is in a free moving state. When the free end of the hydraulic telescopic rod is extended, the inner rod drives the lifting plate upward, and the intersection of the two intersecting inclined rods has an upward jacking force, so that the top sleeves on the left and right sides are close to each other, and the top sleeve drives the treading platform to shorten in length. When the free end of the hydraulic telescopic rod is contracted, similarly, the top sleeves on the left and right sides are close to each other, and then the top sleeve drives the treading platform to extend in length. Therefore, the construction range of the scaffolding can be changed according to needs.

[0018] 4. When the scaffolding of the present invention is leveled, it can be adjusted according to the required height of the construction. First, the four moving wheels are locked to prevent the moving wheels from moving. It only needs to start the hydraulic pump. At this time, the free end of the hydraulic telescopic rod drives the lifting plate to lift and lower. The lifting plate drives the mutually crossed tilting rods to lift and lower. The tilting rods drive the top sliding sleeve and the middle sliding sleeve to lift and lower. The top sliding sleeve and the middle sliding sleeve slide on the support column and make the through hole correspond to any one of the sockets. After adjusting the height, the pin is inserted into the corresponding through hole and socket. Therefore, the height of the stepping platform can be adjusted. The scaffolding has the function of adjusting the height. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0022] The present invention provides the following technical solutions (see Figures 1 to 16 ): See Figure 1 and Figure 4 A quick-install scaffold for construction includes a balancing bracket 1 and a supporting column 2. There are two balancing brackets 1, and a No. 1 level 3 is arranged on the top of the two balancing brackets 1. The No. 1 level 3 measures the left and right horizontal angles. A supporting middle plate 4 is inserted in the middle of the two balancing brackets 1. A hydraulic telescopic rod 5 is arranged in the middle of the supporting middle plate 4. A hydraulic pump 6 is fixedly installed on one side of the hydraulic telescopic rod 5. A No. 2 level 7 is arranged on the other side of the hydraulic telescopic rod 5. The No. 2 level 7 measures the front and rear horizontal angles. A lifting plate 8 is arranged at the free end of the hydraulic telescopic rod 5. Two tilting rods 10 are respectively sleeved on the ends of the lifting plate 8 through nuts 9. The two tilting rods 10 are arranged crosswise with each other.

[0023] More specifically, when the hydraulic pump 6 is started, the hydraulic pump 6 drives the free end of the hydraulic telescopic rod 5 to extend and retract, and the free end of the hydraulic telescopic rod 5 can control the height of the lifting plate 8. The lifting plate 8 drives the two mutually crossed tilting rods 10 to rise and fall, or change the angle of the two mutually crossed tilting rods 10. Through the setting of the No. 1 level 3, the balance bracket 1 is checked to see whether it is in a horizontal state, and through the setting of the No. 2 level 7, the supporting middle plate 4 is checked to see whether it is in a horizontal state.

[0024] See also Fig.13 and Fig.14The support column 2 is sequentially sleeved with a top sliding sleeve 11, a middle sliding sleeve 12 and a bottom sliding sleeve 13 from top to bottom. The inner sides of the top sliding sleeve 11 and the middle sliding sleeve 12 are respectively fixedly connected with a splicing shaft 14. The end of the tilting rod 10 is sleeved on the splicing shaft 14. The inner side of the bottom sliding sleeve 13 is fixedly connected with a support rod 15. The support rod 15 is inserted into the interior of the balancing bracket 1. A plurality of rollers 25 are arranged inside the balancing bracket 1. The support rod 15 is slidably connected to the balancing bracket 1 through the rollers 25.

[0025] More specifically, during use, the ends of the two intersecting inclined rods 10 are buckled and hung on the splicing shaft 14, and the top sliding sleeve 11 and the middle sliding sleeve 12 support each other; the end of the balancing bracket 1 can be sleeved on the end of the support rod 15, so that the balancing bracket 1 and the support rod 15 can be extended and retracted with each other. At this time, the roller 25 and the support rod 15 are in contact with each other. Through the setting of the roller 25, the support rod 15 can be stably extended and retracted in the balancing bracket 1 to improve the smoothness.

[0026] See also Figure 2 , Fig.13 and Fig.14 The left and right sides of the support column 2 are provided with sliding grooves, and the interior of the support column 2 is provided with a plurality of equidistant sockets 16. The inner walls of the top sliding sleeve 11, the middle sliding sleeve 12 and the bottom sliding sleeve 13 are provided with protrusions, which are adapted to the sliding grooves. The inner sides of the middle sliding sleeve 12 and the bottom sliding sleeve 13 are fixedly connected with a fixing plate 24, and the middle sliding sleeve 12 and the bottom sliding sleeve 13 are provided with through holes 17, which are adapted to any one of the sockets 16, and a pin 18 is inserted into the through hole 17 and any one of the sockets 16.

[0027] More specifically, during use, the top sliding sleeve 11, the middle sliding sleeve 12 and the bottom sliding sleeve 13 are slid on the support column 2, and the through hole 17 corresponds to any one of the sockets 16, and the pin 18 is inserted into the corresponding through hole 17 and socket 16, and then the middle sliding sleeve 12 and the bottom sliding sleeve 13 are fixed on the support column 2 to prevent sliding.

[0028] See also Figure 8 and Fig. 9 The free end of the hydraulic telescopic rod 5 comprises an inner rod 501, a top pad 502 and a No. 1 nut 503. The top pad 502 is fixedly connected to the upper surface of the inner rod 501, and the top end of the inner rod 501 is threadedly connected to the No. 1 nut 503.

[0029] More specifically, when the hydraulic pump 6 is started, the inner rod 501 of the hydraulic telescopic rod 5 is freely extended and retracted, and the end of the inner rod 501 is inserted into the interior of the lifting plate 8. At this time, the top pad 502 supports the lifting plate 8, and then the lifting plate 8 is fixed to the inner rod 501 through the No. 2 nut 805.

[0030] See also Figure 1 and Figure 8 The lifting plate 8 includes a prism 801 and a cylinder 802. Both ends of the prism 801 are fixedly connected with the cylinder 802. A spring 803 and a ring 804 are sleeved on the cylinder 802. The prism 801, the spring 803 and the ring 804 are fixed to each other; the cylinder 802 is penetrated at the center of two mutually crossed tilting rods 10, and the end of the cylinder 802 is threadedly connected with a No. 2 nut 805, and a hexagonal nut is arranged at the center of the outer side of the No. 2 nut 805.

[0031] More specifically, when two intersecting tilting rods 10 are installed on the cylinder 802, the collar 804 drives the spring 803 to be compressed and contracted, which facilitates the installation of the ends of the tilting rods 10 on the splicing shaft 14 and prevents the tilting rods 10 from falling off.

[0032] See also Figure 1 There are four top sliding sleeves 11 , and a cross column 19 is fixedly connected between two top sliding sleeves 11 , and a stepping platform 20 is placed on the cross column 19 .

[0033] More specifically, during use, the pedaling platform 20 can be hooked onto the horizontal column 19 for easy use.

[0034] See also Figure 5 , Fig.15 and Figure 6 The pedaling platform 20 includes two edge edges 2001, and the inner sides of the two edge edges 2001 are respectively fixedly connected with multiple sliding rods 2002 and multiple outer tubes 2003. The multiple sliding rods 2002 on the edge edge 2001 and the multiple outer tubes 2003 on the other edge edge 2001 are arranged alternately, and the multiple sliding rods 2002 on one edge edge 2001 are slidably connected with the multiple outer tubes 2003 on the other edge edge 2001, and the sliding rods 2002 can freely expand and contract in the outer tubes 2003; the outer sides of the two edge edges 2001 are respectively fixedly connected with two hooks 2004, and the hooks 2004 are adapted to the cross column 19.

[0035] More specifically, when assembling the scaffolding, the hook 2004 of the treading platform 20 is hooked onto the horizontal column 19, which is easy to use; when the two horizontal columns 19 drive the hook 2004, the hook 2004 drives the two edges 2001 to move away from or closer to each other, and then the two edges 2001 drive the multiple sliding rods 2002 and the multiple outer tubes 2003 to move away from or closer to each other, thereby changing the length of the treading platform 20 and ensuring the construction range.

[0036] See also Figure 3 , Fig.13 and Fig.14A supporting hole 21 is provided at the bottom of the supporting column 2, and a moving wheel 22 is inserted into the supporting hole 21 through an insert shaft 23. A locking pedal is provided on one side of the moving wheel 22, and the insert shaft 23 is located inside the supporting hole 21.

[0037] More specifically, through the matching setting of the plug shaft 23 and the support hole 21, the moving wheel 22 can be assembled into the support hole 21, so that the moving wheel 22 is at the bottom end of the support column 2, which is easy to disassemble. Through the setting of the moving wheel 22, it is easy to move. Through the setting of the locking pedal, the user can lock the moving wheel 22 by pressing the locking pedal to prevent movement.

[0038] The working principle and use process of the present invention: the current scaffolding is generally inconvenient to assemble, transport and occupy space during use; first, the bottom sliding sleeve 13, the middle sliding sleeve 12 and the top sliding sleeve 11 are sequentially mounted on the support column 2, and then the end of the supporting middle plate 4 is inserted into the interior of the balance bracket 1, and then the support rod 15 is inserted into the end of the balance bracket 1, and finally the lifting plate 8 is installed on the top of the free end of the hydraulic telescopic rod 5, and then the lifting plate 8 is fixed by the No. 1 nut 503, and then the two tilting rods 10 are cross-mounted on the ends of the lifting plate 8, and the two cross-leaving tilting rods 10 are limited by the No. 2 nut 805, and then with the use of the spring 803, the user drives the two cross-leaving tilting rods 10 inward by hand to compress the spring 803 and shrink it. At this time, the ends of the two cross-leaving tilting rods 10 can be installed on the splicing shaft 14, and the hand is released to reset the spring 803 and prevent the tilting rod 10 from falling off, so that the scaffold is easy to assemble and disassemble or transport.

[0039] When the scaffold is assembled, if the ground is uneven during use, it is easy to cause the scaffold to tilt, or the support points of the scaffold are not on the same plane, there is shaking, causing safety hazards; when the scaffold is assembled, the four mutually supporting columns 2 rise with the convexity of the ground and fall with the concavity of the ground by their own gravity, so that the supporting columns 2 slide in the top sliding sleeve 11, the middle sliding sleeve 12 and the bottom sliding sleeve 13. At this time, by observing the No. 1 level meter 3, the balance bracket 1 is in a horizontal state left and right, and then by observing the No. 2 level meter 7, the supporting middle plate 4 is in a front and rear state. The scaffold is in a horizontal state, and then the pins 18 are respectively inserted into the corresponding sockets 16 and through holes 17 (the height distance between the two sockets 16 can be ignored and is not used as a reference for the horizontality), so that the four bottom sleeves 13 are in a horizontal state, and the four support columns 2 are in a vertical state. At this time, the middle sleeve 12 is supported on the top of the bottom sleeve 13, and then cooperates with two mutually intersecting inclined rods 10 to support the top sleeve 11. Therefore, the four top sleeves 11 are in a horizontal state, and the stepping platform 20 is leveled to prevent the scaffold from tilting, and has a leveling function.

[0040] When the scaffolding is leveled, during use, the scaffolding usually does not have the ability to adjust the corresponding width, and the length of the platform cannot be changed according to demand, and the construction range is limited; when the scaffolding is leveled, it is only necessary to fix the middle sliding sleeve 12 on the support column 2 through the latch 18 to prevent the middle sliding sleeve 12 from moving up and down, and to make the moving wheel 22 in a free moving state, and then start the hydraulic pump 6, when the inner rod 501 of the hydraulic telescopic rod 5 is extended, the inner rod 501 drives the lifting plate 8 upward, and makes the intersection of the two mutually intersecting inclined rods 10 have an upward jacking force, at this time The tilt rod 10 has an inward pulling force, and makes the support columns 2, the top sliding sleeve 11 and the bottom sliding sleeve 13 on the left and right sides approach each other, so that the upper and lower angles of the two intersecting tilt rods 10 become smaller, and the length of the treading platform 20 driven by the top sliding sleeve 11 is shortened. When the free end of the hydraulic telescopic rod 5 contracts, similarly, the intersection of the two intersecting tilt rods 10 has a downward pulling force, and the top sliding sleeves 11 on the left and right sides approach each other, and then the top sliding sleeve 11 drives the treading platform 20 to extend in length. Therefore, the construction range of the scaffolding can be changed according to needs.

[0041] When the scaffolding is adjusted to a construction range, during use, the scaffolding usually does not have the function of raising and lowering, and its use is limited; when the scaffolding is leveled, the four moving wheels 22 are first locked to prevent the moving wheels 22 from moving, and the hydraulic pump 6 only needs to be started. At this time, the inner rod 501 of the hydraulic telescopic rod 5 drives the lifting plate 8 to rise and fall, and the lifting plate 8 drives the mutually crossed tilting rods 10 to rise and fall, and the tilting rods 10 drive the top sliding sleeve 11 and the middle sliding sleeve 12 to rise and fall, so that the top sliding sleeve 11 and the middle sliding sleeve 12 slide on the support column 2, and the through hole 17 corresponds to any one of the sockets 16 (the height distance between the two sockets 16 can be ignored and is not used as a reference for the height), and the pin 18 is inserted into the corresponding through hole 17 and the socket 16 after adjusting the height (the free end of the hydraulic telescopic rod 5 is not affected by external force to change its own extension length, and the free end of the hydraulic telescopic rod 5 is controlled by the hydraulic pump 6), so the height of the stepping platform 20 can be adjusted, and the scaffolding has the function of adjusting the height.

[0042] A method for using a quick-install scaffold for construction comprises the following steps: S1. First, install the bottom sliding sleeve 13, the middle sliding sleeve 12 and the top sliding sleeve 11 on the support column 2 in sequence, and assemble them with the supporting middle plate 4, the balance bracket 1 and the support rod 15, so that the lifting plate 8 is installed on the free end of the hydraulic telescopic rod 5, and then install the two tilting rods 10 crosswise at the ends of the lifting plate 8, and then install the ends of the two cross tilting rods 10 on the splicing shaft 14 for easy disassembly; S2. When the scaffold is assembled, the four support columns 2 rise with the ground bulge and fall with the ground sag by their own gravity. By observing the settings of the No. 1 level 3 and the No. 2 level 7, the balance bracket 1 and the support middle plate 4 are in a horizontal state. Then, the pins 18 are respectively inserted into the corresponding sockets 16 and through holes 17, so that the four bottom sliding sleeves 13 are in a horizontal state, and the four top sliding sleeves 11 are in a horizontal state, and the stepping platform 20 is leveled to prevent the scaffold from tilting, and it has a leveling function. S3. When the scaffolding is leveled, it is only necessary to fix the middle sliding sleeve 12 on the supporting column 2 through the latch 18 to prevent the middle sliding sleeve 12 from moving up and down, and the moving wheel 22 is in a free moving state. When the free end of the hydraulic telescopic rod 5 is extended, the inner rod 501 drives the lifting plate 8 upward, and the intersection of the two intersecting inclined rods 10 has an upward jacking force, so that the top sliding sleeves 11 on the left and right sides are close to each other, and the top sliding sleeves 11 drive the length of the treading platform 20 to shorten. When the free end of the hydraulic telescopic rod 5 is retracted, similarly, the top sliding sleeves 11 on the left and right sides are close to each other, and the top sliding sleeves 11 drive the length of the treading platform 20 to extend, so the construction range of the scaffolding is changed according to demand; S4. When the scaffolding is leveled, the four moving wheels 22 are first locked to prevent the moving wheels 22 from moving. It is only necessary to drive the lifting plate 8 to be lifted or lowered by the free end of the hydraulic telescopic rod 5. The lifting plate 8 drives the mutually crossed tilting rods 10 to be lifted or lowered. The tilting rods 10 drive the top sliding sleeve 11 and the middle sliding sleeve 12 to be lifted or lowered, and make the through hole 17 correspond to any one of the sockets 16. After adjusting the height, the pin 18 is inserted into the corresponding through hole 17 and the socket 16, so as to adjust the height of the stepping platform 20.

10. The method for using a quick-install scaffold for construction according to claim 9, characterized in that: The following steps are involved: S1. First, the bottom sliding sleeve (13), the middle sliding sleeve (12) and the top sliding sleeve (11) are sequentially installed on the support column (2), and the supporting middle plate (4), the balancing bracket (1) and the support rod (15) are assembled so that the lifting plate (8) is installed on the free end of the hydraulic telescopic rod (5). Then, the two tilting rods (10) are cross-mounted on the ends of the lifting plate (8), and the ends of the two cross-tilting rods (10) can be installed on the splicing shaft (14) for easy disassembly; S2. When the scaffold is assembled, the four support columns (2) rise up as the ground bulges and fall down as the ground sags due to their own gravity. By observing the settings of the No. 1 level meter (3) and the No. 2 level meter (7), the balance bracket (1) and the support middle plate (4) are checked to see whether they are in a horizontal state. Then, the pins (18) are respectively inserted into the corresponding sockets (16) and through holes (17), so that the four bottom sliding sleeves (13) are in a horizontal state. Therefore, the four top sliding sleeves (11) are in a horizontal state, and the stepping platform (20) is leveled to prevent the scaffold from tilting, thereby having a leveling function. S3. When the scaffolding is leveled, it is only necessary to fix the middle sliding sleeve (12) on the supporting column (2) by means of the latch (18) to prevent the middle sliding sleeve (12) from moving up and down, and the moving wheel (22) is in a free moving state. When the free end of the hydraulic telescopic rod (5) is extended, the inner rod (501) drives the lifting plate (8) upward, and the intersection of the two mutually intersecting inclined rods (10) has an upward pushing force, so that the top sliding sleeves (11) on the left and right sides are close to each other, and the top sliding sleeves (11) drive the length of the stepping platform (20) to be shortened. When the free end of the hydraulic telescopic rod (5) is retracted, similarly, the top sliding sleeves (11) on the left and right sides are close to each other, and the top sliding sleeves (11) drive the length of the stepping platform (20) to be extended, so that the construction range of the scaffolding is changed according to demand. S4. When the scaffolding is leveled, the four moving wheels (22) are first locked to prevent the moving wheels (22) from moving. The free end of the hydraulic telescopic rod (5) only needs to drive the lifting plate (8) to move up and down. The lifting plate (8) drives the mutually crossed tilting rods (10) to move up and down. The tilting rods (10) drive the top sliding sleeve (11) and the middle sliding sleeve (12) to move up and down, and make the through hole (17) correspond to any one of the plug holes (16). After adjusting the height, the pin (18) is inserted into the corresponding through hole (17) and the plug hole (16). Thus, the height of the stepping platform (20) is adjusted. Therefore, the scaffolding has the function of adjusting the height.
