Description

Technical Field

[0001] The invention relates to the technical field of construction equipment, and in particular to a construction scaffold for construction engineering. Background Art

[0002] Scaffolding is a kind of construction tool used in construction to facilitate workers to operate at heights. On the outside of the building, steel pipes are generally used to build scaffolding. This kind of scaffolding is taller and more practical. However, when steel pipes are used to build scaffolding indoors, the construction is more complicated. After all, the indoor space is small and the steel pipes are not easy to store.

[0003] After searching, the Chinese patent application number CN201510677426.5 discloses an indoor decoration scaffolding, including a bracket formed by overlapping horizontal bars and vertical bars, an upper foot pedal and a lower foot pedal are arranged on the bracket, a lower foot pedal support assembly is arranged below the upper foot pedal, and the lower foot pedal support assembly includes a support rod and two track grooves, the two track grooves are respectively fixed to the two sides of the support frame, the grooves of the two track grooves are opposite, and the two ends of the support rod are respectively fixed to the bottom surface of the same end of the two track grooves. The indoor decoration scaffolding in the above patent has the following shortcomings: the fixed scaffolding can only be used to construct part of the wall area on the platform, and cannot be used to construct a large area of ​​the wall. If you want to construct a large area, you need to build more scaffolding, which is inconvenient. Summary of the invention

[0004] Based on the fact that fixed scaffolding can only be used to construct part of the wall area on the platform, more scaffolding needs to be built for large-scale construction, which is a relatively inconvenient technical problem. The present invention proposes a construction scaffolding for construction engineering.

[0005] The sled is equipped with a plurality of movable members, each of which is connected to a plurality of movable members at a plurality of locations on the sled, and the movable members are connected to the plurality of movable members at a plurality of locations on the sled.

[0006] Preferably, hydraulic oil is provided inside the first fixing sleeve and the second fixing sleeve, an arc-shaped groove is provided on the outer wall of the roller, and the rotating rod is located inside the arc-shaped groove.

[0007] Preferably, a first through hole is opened in the middle of the support plate, a fixing rod is provided at the first through hole, two fixing blocks are welded at the top of the movable plate, both ends of the fixing rod are respectively welded to the two fixing blocks, and support springs are welded between the two sides of the bottom end of the support plate and the movable plate.

[0008] Preferably, a second through hole is opened in the middle of the rotating rod, and a rack is provided at the second through hole of the rotating rod, the top of the rack is welded to the moving rod, and a gear is connected to the middle of the fixed shaft through a key, and the gear is meshed with the rack.

[0009] Preferably, guardrails are welded on three sides of the support plate.

[0010] Preferably, support blocks are welded on both sides of the bottom end of the base, a positioning column is welded on one side of the support block, a rotating shaft is welded on both sides of the base, one end of the rotating shaft is rotatably connected to a support rod, and a universal wheel is welded on the bottom end of the support rod.

[0011] The beneficial effects of the present invention are:

[0012] 1. By setting support columns, fixed sleeves, hydraulic pipes, movable columns, support plates and fixed rods, when a worker approaches one side of the support plate, the support plate increases the pressure on the worker's side through the lever action of the fixed rod. The closer to the edge, the greater the pressure. The support plate squeezes the first support column, and the first support column compresses the hydraulic oil inside the first fixed sleeve, and drives the two second movable columns to move through the first hydraulic pipe or the second hydraulic pipe. The second movable column drives the rotating rod to rotate, and the rotating rod moves the movable plate, ensuring that the workers can construct a larger wall area.

[0013] 2. By setting a support spring, when the support plate descends, the elastic force of the support spring will become greater and greater as the support plate descends, until the weight of the human body is balanced with the elastic force of the support spring, thereby preventing the rotating rod from rotating continuously due to the weight of the human body.

[0014] 3. By setting the gear and the rack, when the rotating rod rotates to the left, the rotating rod drives the gear to rotate counterclockwise. At this time, the gear will drive the moving rod to move upward through the rack, and the moving rod will extend, ensuring that the moving plate is always at the same height during the moving process. When the rotating rod rotates to the right, the rotating rod drives the gear to rotate clockwise. At this time, the gear will drive the moving rod to move downward through the rack, and the moving rod will shorten, ensuring that the moving plate is always at the same height during the moving process.

[0015] 4. By setting the gear and rack, when the rotating rod rotates to the other side of the device through the meshing of the gear and the rack, the moving rod will continue to shorten, and the moving plate will drop until the second moving column cannot move, and the moving plate drops to the lowest point, which is convenient for workers to get off the device and also convenient for the folding of the device.

[0016] 5. By setting the support rod, positioning column and universal wheel, rotate the support rod to make it contact the positioning column. At this time, the gravity of the device makes the support rod tightly contact the positioning column and cannot rotate. The device can be moved by the universal wheel.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1

[0025] Reference Figure 1-3A construction scaffold for construction engineering, comprising a base 1, four through holes are opened at the top of the base 1, the base 1 is rotatably connected to a rotating rod 2 at the four through holes through a fixed shaft 15, a moving rod 3 is arranged at the top of the rotating rod 2, the tops of the four moving rods 3 are rotatably connected to the same moving plate 4, a supporting plate 6 is arranged at the top of the moving plate 4, first moving columns 7 are arranged on both sides of the bottom end of the supporting plate 6, a first fixing sleeve 8 is arranged at the bottom end of the first moving column 7, a circular through hole is opened on one side of the first fixing sleeve 8, and a first hydraulic pipe 9 and a second hydraulic pipe 9 are respectively connected to the two first fixing sleeves 8 at the circular through holes by threads A fixed body 20 is welded to the middle of the top of the hydraulic pipe 12 and the base 1, and second fixed sleeves 19 are welded to both sides of the top of the fixed body 20. The first hydraulic pipe 9 and the second hydraulic pipe 12 are respectively connected to the tops of the two fixed sleeves 19 by threads. A second movable column 18 is provided at one end of the second fixed sleeve 19, and a push rod 17 is welded to one end of the second movable column 18. Both ends of the push rod 17 are rotatably connected to rollers 16, and the rollers 16 are in contact with the rotating rod 2. The push rod 17 can push the rotating rod 2 to rotate through the second movable column 18 to change the position of the movable plate 3, so that workers can operate a larger area of ​​the wall.

[0026] In the present invention, hydraulic oil is provided inside the first fixed sleeve 8 and the second fixed sleeve 19. Through the first hydraulic pipe 9 and the second hydraulic pipe 12, the two first movable columns 7 can respectively drive the second movable column 18 to move, so that the rotating rod 2 rotates and the position of the movable plate 3 is changed. An arc-shaped groove is provided on the outer wall of the roller 16, and the rotating rod 2 is located inside the arc-shaped groove. The arc-shaped groove makes it convenient for the rotating rod 2 to not deviate when the roller 16 pushes the rotating rod 2, thereby preventing the roller 16 from separating from the rotating rod 2.

[0027] Among them, a first through hole is opened in the middle of the support plate 6, and a fixing rod 10 is provided at the first through hole of the support plate 6. Two fixing blocks 11 are welded on the top of the movable plate 4, and the two ends of the fixing rod 10 are respectively welded to the two fixing blocks 11. Support springs 5 ​​are welded between the two sides of the bottom end of the support plate 6 and the movable plate 4. The support plate 6 can be rotated by the fixing rod 10. When the worker approaches one side of the support plate 6, the pressure on one side of the support plate 6 will gradually increase, squeezing the first support column 7. The first support column 7 compresses the hydraulic oil inside the first fixed sleeve 8, and drives the two second moving columns 18 to move through the first hydraulic pipe 9 or the second hydraulic pipe 12. The second moving column 18 pushes the rotating rod 2 to rotate. At the same time, as the support plate 6 descends, the elastic force of the support spring 5 becomes larger and larger until the weight of the human body is balanced with the elastic force of the support spring 5, so as to prevent the rotating rod 2 from rotating all the time due to the weight of the human body.

[0028] Among them, a second through hole is opened in the middle of the rotating rod 2, and a rack 13 is provided at the second through hole of the rotating rod 2. The top of the rack 13 is welded to the moving rod 3, and the middle part of the fixed shaft 15 is connected with a gear 14 through a key. The gear 14 is meshed with the rack 13. When the rotating rod 2 rotates to the left, the rotating rod 2 drives the gear 14 to rotate counterclockwise. At this time, the gear 14 will drive the moving rod 3 to move upward through the rack 13, and the moving rod 3 will extend to ensure that the moving plate 4 is always at the same height during the moving process. When the rotating rod 2 rotates to the right, the rotating rod 2 drives the gear 14 to rotate clockwise. At this time, the gear 14 will drive the moving rod 3 to move downward through the rack 13, and the moving rod 3 will shorten to ensure that the moving plate 4 is always at the same height during the moving process. When the rotating rod 2 rotates to the other side, the moving rod 3 continues to shorten. At this time, the moving plate 4 drops until the second moving column 18 cannot move. The moving plate 4 drops to the lowest point, which is convenient for workers to get off the device and at the same time convenient for the folding of the device.

[0029] Among them, guardrails 601 are welded on three sides of the support plate 6. The guardrails 601 on the three sides prevent construction workers from falling, increase safety, and facilitate construction.

[0030] When in use, when a worker approaches one side of the support plate 6, the pressure on one side of the support plate 6 will gradually increase. The support plate 6 uses the lever action of the fixed rod 10, and the pressure on the side where the worker is located will increase. The closer to the edge, the greater the pressure. The support plate 6 squeezes the first support column 7, and the first support column 7 compresses the hydraulic oil inside the first fixed sleeve 8, and drives the two second moving columns 18 to move through the first hydraulic pipe 9 or the second hydraulic pipe 12. The second moving column 18 pushes the rotating rod 2 to rotate. At the same time, the elastic force of the support spring 5 becomes larger and larger as the support plate 6 descends, until the weight of the human body is balanced with the elastic force of the support spring 5, so as to prevent the rotating rod 2 from rotating all the time due to the weight of the human body;

[0031] When the rotating rod 2 is rotating to the left, the rotating rod 2 drives the gear 14 to rotate counterclockwise. At this time, the gear 14 will drive the moving rod 3 to move upward through the rack 13, and the moving rod 3 will extend to ensure that the moving plate 4 is always at the same height during the moving process. When the rotating rod 2 is rotating to the right, the rotating rod 2 drives the gear 14 to rotate clockwise. At this time, the gear 14 will drive the moving rod 3 to move downward through the rack 13, and the moving rod 3 will shorten to ensure that the moving plate 4 is always at the same height during the moving process. When the rotating rod 2 is rotated to the other side, the moving rod 3 continues to shorten. At this time, the moving plate 4 drops until the second moving column 18 cannot move. The moving plate 4 drops to the lowest point, which is convenient for workers to get off the device and for the folding of the device.

[0032] Example 2

[0033] Reference Figure 4-5A construction scaffold for construction engineering. Compared with Example 1, in order to increase the convenience of the device and facilitate the movement of the device, support blocks 21 are welded on both sides of the bottom end of the base 1, and a positioning column 22 is welded on one side of the support block 21. A rotating shaft 25 is welded on both sides of the base 1, and one end of the rotating shaft 25 is rotatably connected to a support rod 24. A universal wheel 23 is welded on the bottom end of the support rod 24. The support rod 24 is rotated to contact the positioning column 22. At this time, the gravity of the device makes the support rod 24 tightly contact the positioning column 22 and cannot rotate. The device can be moved by the universal wheel 23.

[0034] When in use, when a worker approaches one side of the support plate 6, the pressure on one side of the support plate 6 will gradually increase, squeezing the first support column 7. The first support column 7 compresses the hydraulic oil inside the first fixed sleeve 8, and drives the two second moving columns 18 to move through the first hydraulic pipe 9 or the second hydraulic pipe 12. The second moving column 18 pushes the rotating rod 2 to rotate. At the same time, the elastic force of the support spring 5 becomes larger and larger as the support plate 6 descends, until the weight of the human body is balanced with the elastic force of the support spring 5, so as to prevent the rotating rod 2 from rotating all the time due to the weight of the human body;

[0035] When the rotating rod 2 is rotating to the left, the rotating rod 2 drives the gear 14 to rotate counterclockwise. At this time, the gear 14 drives the moving rod 3 to move upward through the rack 13, and the moving rod 3 is extended to ensure that the moving plate 4 is always at the same height during the moving process. When the rotating rod 2 is rotating to the right, the rotating rod 2 drives the gear 14 to rotate clockwise. At this time, the gear 14 drives the moving rod 3 to move downward through the rack 13, and the moving rod 3 is shortened to ensure that the moving plate 4 is always at the same height during the moving process. When the rotating rod 2 is rotated to the other side, the moving rod 3 continues to shorten. At this time, the moving plate 4 drops until the second moving column 18 cannot move. The moving plate 4 drops to the lowest point, which is convenient for workers to get off the device and for the folding of the device.

[0036] The support rod 24 is rotated to contact the positioning column 22 . At this time, the gravity of the device makes the support rod 24 tightly contact the positioning column 22 and cannot rotate. The device can be moved by the universal wheel 23 .
