[0004] The above-mentioned equipment is convenient for the transmission of items by setting structures such as a base, moving wheels, hydraulic telescopic rods, and a lifting seat. However, when the equipment moves up and down, only the hydraulic telescopic rods at the bottom are used as supports, and there is a lack of a limiting structure on its side. It is easy to shake during the ascending and descending process, and it is easy for the construction scaffold to slip when relying solely on the hydraulic telescopic rods as supports under the condition of a large load, and the safety of construction workers is low. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a construction scaffold with a falling prevention structure for construction, which solves the problems of easy shaking during ascending and descending and low safety when the load is large existing nowadays.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A construction scaffold with a falling prevention structure for construction, including an equipment main body, a control panel, and a cylinder. The control panel is arranged on the upper end surface of the equipment main body, and the cylinder is arranged at the upper end of the equipment main body;

[0007] A falling prevention construction scaffold is arranged above the equipment main body. A rack is arranged at the side end of the falling prevention construction scaffold. A connecting plate is arranged on the outer peripheral end surface of the rack. A cooperating gear is arranged inside the bottom end of the falling prevention construction scaffold;

[0008] The anti-falling construction frame further includes a motor and a pawl. The motor is fixedly connected to the outer end face of the anti-falling construction frame, and the pawl is movably connected to the outside of the motor.

[0009] As a preferred technical solution of the present invention, four groups of racks are provided, and a strip structure is provided on the outer end face of the rack. The strip structure is embedded in the inner side of the connecting plate and a sliding connection relationship is established.

[0010] As a preferred technical solution of the present invention, four groups of coupling gears are provided, with every two groups as a pair, which are respectively distributed on the left and right sides of the anti-falling construction frame and mesh with the tooth grooves of the rack.

[0011] As a preferred technical solution of the present invention, the coupling gear further includes a shaft column and a ratchet wheel. The shaft column is movably connected to the inner side of each pair of coupling gears, and the shaft column near the ratchet wheel penetrates through the coupling gear. The ratchet wheel is fixedly connected to the outer end of the shaft column.

[0012] As a preferred technical solution of the present invention, the ratchet teeth on the periphery of the ratchet wheel correspond to the pawl. During the rising process of the anti-falling construction frame, the ratchet wheel on the left rotates counterclockwise, and the ratchet wheel on the right rotates clockwise.

[0013] As a preferred technical solution of the present invention, four groups of cylinders are provided, which are symmetrically distributed on the left and right sides of the equipment main body, and a push rod is further extended at the upper end thereof and fixedly connected to the anti-falling construction frame.

[0014] As a preferred technical solution of the present invention, two groups of connecting plates are provided, and they need to be connected to the external fixed position through a bolt structure before use.

[0015] Compared with the prior art, the present invention provides a construction frame for building construction with an anti-falling structure:

[0016] The construction frame with an anti-falling structure for construction is provided with an anti-falling construction frame, a rack, a connecting gear, a ratchet and a pawl. When the equipment is used, the operator controls the start and stop of the cylinder and the motor through the control panel. After the construction personnel enter the anti-falling construction frame, the operator controls the cylinder to lift the anti-falling construction frame until it reaches the construction height and stops. In this process, the connecting gears on both sides of the anti-falling construction frame rotate on the inner side of the rack through the support of the shaft columns on both sides, so that the anti-falling construction frame as a whole tends to be stable. When the connecting gears rotate, the outer ratchet rotates at the same time through the transmission of the shaft column, the left ratchet rotates counterclockwise, and the right ratchet rotates clockwise. When the ratchet rotates, the pawl at the corresponding position is toggled until the rising stroke of the anti-falling construction frame is completed. When the construction personnel complete the construction and need to return to the ground, the operator needs to control the motor to start first, and the motor drives the pawl to toggle outward, so that the ratchet at the corresponding position can rotate in the opposite direction. At this time, the cylinder is controlled to support the anti-falling construction frame to slowly descend.

[0017] The above settings and processes can make the device have the following beneficial effects:

[0018] Through the cooperation of four sets of racks, connecting gears and shaft columns, the anti-falling construction frame can keep its position fixed during the process of being lifted by the cylinder to prevent shaking. Through the cooperation of the shaft column, ratchet, pawl and motor, the anti-falling construction frame can keep smooth during the rising process, and the pawl needs to be moved first when descending, so that the anti-falling construction frame can be ensured not to fall when it is in a higher position, which not only improves the stability of the equipment during ascent and descent, but also greatly increases the safety of construction workers.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to the following implementation solution: A construction scaffold with a fall prevention structure for construction, comprising an equipment main body 1, a control panel 2, and a cylinder 3. The control panel 2 is arranged on the upper end surface of the equipment main body 1, and the cylinder 3 is arranged at the upper end of the equipment main body 1.

[0026] Above the equipment main body 1, a fall prevention construction scaffold 4 is arranged. A rack 5 is arranged on the side end of the fall prevention construction scaffold 4. A connecting plate 6 is arranged on the outer peripheral end surface of the rack 5. A linking gear 7 is arranged on the inner side of the bottom end of the fall prevention construction scaffold 4.

[0027] The fall prevention construction scaffold 4 further comprises a motor 401 and a pawl 402. The motor 401 is fixedly connected to the outer end surface of the fall prevention construction scaffold 4, and the pawl 402 is movably connected to the outside of the motor 401.

[0028] In this embodiment, four groups of racks 5 are arranged, and a strip-shaped structure is arranged on the outer end surface of the rack 5. The strip-shaped structure is embedded in the inner side of the connecting plate 6 and a sliding connection relationship is established; Four groups of linking gears 7 are arranged, and every two groups are a pair, which are respectively distributed on the left and right sides of the fall prevention construction scaffold 4 and mesh with the tooth grooves of the rack 5.

[0029] Specifically, as Figure 2 and Figure 4 shown, when the fall prevention construction scaffold 4 moves up and down, the linking gear 7 rotates inside the rack 5 following the movement of the fall prevention construction scaffold 4, and the two side linking gears 7 are kept synchronized through a shaft column 701.

[0030] In this embodiment, the linking gear 7 further comprises a shaft column 701 and a ratchet wheel 702. The shaft column 701 is movably connected to the inner side of each pair of linking gears 7, and the shaft column 701 near the ratchet wheel 702 penetrates through the linking gear 7. The ratchet wheel 702 is fixedly connected to the outer end of the shaft column 701; The ratchet teeth on the periphery of the ratchet wheel 702 correspond to the pawl 402. During the ascending process of the fall prevention construction scaffold 4, the ratchet wheel 702 on the left side rotates counterclockwise, while the ratchet wheel 702 on the right side rotates clockwise.

[0031] Specifically, as Figure 3 and Figure 4 shown, the ratchet wheel 702 rotates following the rotation of the shaft column 701, and the rotation directions of the two side ratchet wheels 702 are opposite. The ratchet wheel 702 can be controlled by the pawl 402 installed at different positions.

[0032] In this embodiment, four groups of cylinders 3 are provided, and are symmetrically distributed on the left and right sides of the equipment body 1. Push rods are also extended from the upper ends to be fixedly connected to the anti-slip construction frame 4; two groups of connecting plates 6 are provided, which need to be connected to the external fixed position through a bolt structure before use.

[0033] The working principle and use process of the utility model are as follows: the operator controls the start and stop of the cylinder 3 and the motor 401 through the control panel 2. After the construction personnel enter the anti-slip construction frame 4, the operator controls the cylinder 3 to lift the anti-slip construction frame 4 until it reaches the construction height and stops. In this process, the connecting gears 7 on both sides of the anti-slip construction frame 4 rotate on the inner side of the rack 5 through the support of the shaft columns 701 on both sides, so that the anti-slip construction frame 4 as a whole tends to be stable. When the connecting gear 7 rotates, the transmission of the shaft column 701 causes the outer ratchet 702 to rotate at the same time, the left ratchet 702 rotates counterclockwise, and the right ratchet 702 rotates clockwise. When the ratchet 702 rotates, the ratchet 402 at the corresponding position is dialed until the rising stroke of the anti-slip construction frame 4 is completed. When the construction personnel complete the construction and need to return to the ground, the operator needs to control the motor 401 to start first, and the motor 401 drives the ratchet 402 to dial outward, so that the ratchet 702 at the corresponding position can rotate in the opposite direction. At this time, the cylinder 3 is controlled to support the anti-slip construction frame 4 to slowly descend.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
