Description

Technical Field

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

[0002] In construction projects, operators will use scaffolding for construction. Scaffolding is a working platform set up to ensure the smooth progress of each construction process.

[0003] In order to reach the specified height when the scaffold is in use, the scaffold is assembled, and the connection points are locked with bolts after the scaffold is assembled. However, this type of scaffold has the following shortcomings when in use: the scaffold needs to be assembled frequently during use and cannot be automatically lifted and lowered, which not only increases the workload of the operator, but also prolongs the time consumed for assembling the scaffold; and because bolts are used to position the connection points after the scaffold is assembled, if the bolts are corroded, rusted, or broken during use, the connection points of the scaffold will slip, making it impossible to protect the safety of the operator. Utility Model Content

[0004] The utility model aims to solve the problem of scaffolding slippage caused by connecting scaffolding connection points with bolts in the prior art, and proposes a construction engineering scaffolding.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A scaffold for construction engineering comprises a base with movable wheels, the base is provided with guide rails, a lifting plate and a safety rail, the guide rails are arranged on the base, and the safety rails are arranged on the lifting plate, a guide rod matched with the guide rails is fixedly mounted on the base, and a sliding block is provided on the guide rod, the lifting plate is arranged between four sliding blocks, a hydraulic cylinder connected with the lifting plate is fixedly mounted on the base, six positioning holes are provided on the guide rails, and a positioning groove corresponding to the positioning holes is provided on the sliding block, and a positioning component for positioning the sliding block is installed on the lifting plate.

[0007] Preferably, the four guide rails are vertically arranged and are of L-shaped structure, an escalator is provided on the lifting plate, and a safety rope is provided in the safety fence.

[0008] Preferably, the positioning assembly includes four supports fixedly mounted on the lifting plate, each of the four supports having a motor fixedly mounted therein, the output end of the motor being fixedly connected to a screw rod rotatably mounted in the support, a matching nut being mounted on the screw rod, and a traction plate being integrally connected to the nut, and a positioning rod corresponding to the positioning hole and extending into the positioning groove being integrally connected to the traction plate.

[0009] Preferably, the screw rod is arranged horizontally, and a limiting rod for guiding the nut is installed on the support.

[0010] Preferably, the lifting plate and the base are horizontally arranged from top to bottom, and the four guide rods are vertically arranged.

[0011] Preferably, the six positioning holes are equidistantly distributed in a straight line along the vertical direction.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model drives the lifting plate to move the safety rail up and down through the drive of the hydraulic cylinder, so that there is no need to assemble the scaffolding when adjusting the height of the lifting plate, thereby reducing the operation intensity and the time consumed by frequent disassembly. The slide block is guided by the guide rod to ensure the stability of the lifting plate when moving.

[0014] 2.

[0020] 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 of the embodiments.

[0021] Reference Figure 1-Figure 4 A construction engineering scaffold comprises a base 1 provided with moving wheels, a guide rail 2, a lifting plate 5, and a safety fence 6 are provided on the base 1, the guide rail 2 is provided on the base 1, and the safety fence 6 is provided on the lifting plate 5, four guide rails 2 are vertically arranged, and the guide rails 2 are L-shaped structures, an escalator is provided on the lifting plate 5, and a safety rope is provided in the safety fence 6;

[0022] A guide rod 3 matching the guide rail 2 is fixedly mounted on the base 1, and a slider 4 is slidably sleeved on the guide rod 3. The lifting plate 5 and the base 1 are horizontally arranged from top to bottom, and four guide rods 3 are vertically arranged. The lifting plate 5 is arranged between the four sliders 4. The guide rod 3 and the guide rail 2 guide the slider 4, so that the slider 4 can smoothly drive the lifting plate 5 to move when moving.

[0023] A hydraulic cylinder 7 connected to the lifting plate 5 is fixedly installed on the base 1, six positioning holes 8 are opened on the guide rail 2, and a positioning groove 9 corresponding to the positioning holes 8 is opened on the slider 4. The lifting plate 5 is driven to move by the output end of the hydraulic cylinder 7, so that the lifting plate 5 can drive the safety fence 6 to move up to a specified height. It should be noted that the telescopic distance of the hydraulic cylinder 7 can correspond to the positioning hole 8, so that the slider 4 can drive the positioning groove 9 to correspond to the positioning hole 8 after moving, and a positioning component for positioning the slider 4 is installed on the lifting plate 5;

[0024] The positioning assembly includes four supports 10 fixedly mounted on the lifting plate 5, and a motor 11 is fixedly mounted in each of the four supports 10. The output end of the motor 11 is fixedly connected to a screw rod 12 rotatably mounted in the support 10, and a matching nut 13 is mounted on the screw rod 12, and a traction plate 14 is integrally connected to the nut 13;

[0025] The screw rod 12 is arranged horizontally, and a limiting rod for guiding the nut 13 is installed on the support 10. A positioning rod 15 corresponding to the positioning hole 8 and extending into the positioning groove 9 is integrally connected to the traction plate 14. The screw rod 12 is driven to rotate by the output end of the motor 11, so that the nut 13 slides with the limiting rod as a fulcrum. When the nut 13 moves, it drives the traction plate 14 and the positioning rod 15 to move, so that the positioning rod 15 can pass through the positioning hole 8 and extend into the positioning groove 9 in the slider 4, so as to lock the position of the slider 4, prevent the lifting plate 5 from slipping, thereby improving the construction efficiency and the safety of the operator during construction.

[0026] Please refer to the instruction manual for details Figure 1 With attached Figure 2 The six positioning holes 8 are evenly distributed in a straight line along the vertical direction, so as to limit the position of the slider 4 and the lifting plate 5 at six height positions.

[0027] It should be noted that the specific models and specifications of the hydraulic cylinder 7 and the motor 11 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] Move the base 1 to a designated position via the moving wheels;

[0030] The operator enters the safety fence 6 through the escalator and uses a safety rope to protect himself;

[0031] The output end of the hydraulic cylinder 7 is extended and retracted to drive the lifting plate 5 to move upward;

[0032] When the lifting plate 5 moves, the slider 4 slides on the guide rod 3, so that the lifting plate 5 can drive the operator to rise to a specified height;

[0033] When the lifting plate 5 rises to a specified height, the hydraulic cylinder 7 is closed, and the height of the slider 4 can correspond to one of the positioning holes 8;

[0034] The output end of the motor 11 drives the screw rod 12 to rotate, and the screw rod 12 drives the nut 13 to slide when rotating. When the nut 13 slides on the limit rod, it drives the traction plate 14 to move toward one side of the guide rail 2, so that the traction plate 14 drives the positioning rod 15 to pass through the positioning hole 8 and extend into the positioning groove 9;

[0035] After the positioning rod 15 positions the slider 4, the motor 11 is turned off and the operator can perform construction work;

[0036] If the height of the lifting plate 5 needs to be adjusted, the output end of the motor 11 drives the screw rod 12 to rotate in the opposite direction, so that the positioning rod 15 is disconnected from the slider 4 and the positioning hole 8. After the output end of the hydraulic cylinder 7 adjusts the height of the lifting plate 5, the motor 11 is turned on again so that the positioning rod 15 can lock the position of the slider 4.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
