Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and more specifically to an adjustable mechanical safety guardrail device. Background Technology

[0002] Safety railings, also known as industrial safety railings or crash barriers, are primarily used for the protection of equipment and facilities in factories, workshops, and warehouses. They are commonly made of steel, such as round steel pipes, square steel pipes, or profiled steel sheets. Surface treatment processes include fully automatic electrostatic powder coating or painting. Outdoor crash barriers use waterproof materials for surface treatment, resulting in aesthetically pleasing and rust-resistant railings.

[0003] After a period of use, existing guardrails accumulate a lot of dust and impurities on their protective netting. Since existing guardrails do not have an automatic cleaning function, staff need to clean the dust and impurities on the netting regularly in order to maintain aesthetics. Usually, brush rollers are used to clean the dust and impurities on the netting, which increases the workload of the staff and does not allow for automatic cleaning of the netting. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable mechanical safety guardrail device to solve the problems in the background art.

[0005] This utility model provides the following technical solution: an adjustable mechanical safety guardrail device, including a first support column, a second support column, and a protective net fixedly installed between the first support column and the second support column, and also including two brush rollers. The protective net is located between the two brush rollers. A limiting groove is opened on the side of the first support column near the protective net. Two sets of angle adjustment components that drive the two brush rollers to rotate are symmetrically arranged in the limiting groove. A drive component that drives the two sets of angle adjustment components to rotate and reciprocate along the limiting groove is arranged in the limiting groove. A lifting component is provided at the bottom of both the first support column and the second support column.

[0006] Furthermore, the drive assembly includes a first motor, a reciprocating lead screw, and a slider. The first motor is fixedly installed in the limiting groove. One end of the reciprocating lead screw is fixedly connected to the output end of the first motor, and the other end is rotatably connected to the inner wall of the limiting groove. The slider is sleeved on the lead screw and slides in cooperation with the limiting groove.

[0007] Furthermore, the drive assembly also includes two racks and two gears. The two gears are symmetrically connected to the slider for rotation, and the two racks are symmetrically fixed in the limiting groove. The two gears mesh with the corresponding racks respectively.

[0008] Furthermore, the angle adjustment assembly includes a disc, two fixed blocks, a rotating rod, and a second motor. The disc is fixedly mounted on a gear, the two fixed blocks are symmetrically fixedly mounted on the disc, the second motor is fixedly mounted on one of the two fixed blocks, one end of the rotating rod is fixedly connected to the output end of the second motor, and the other end passes through the corresponding fixed block and is rotatably connected to the other fixed block.

[0009] Furthermore, the two brush rollers are respectively fixedly connected to the two rotating rods.

[0010] Furthermore, both sets of lifting components include a connecting block, a base, and an electric push rod. The electric push rod is fixedly installed inside the base, and its output end is fixedly connected to the connecting block. The connecting block is located directly above the base, and the two connecting blocks are fixedly connected to the bottom of the first support column and the second support column, respectively.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, a second motor drives a rotating rod to rotate, which in turn rotates the brush roller 90 degrees, causing the brush roller to rotate out of the limiting groove. The drive assembly then drives the disc, two fixed blocks, the rotating rod, the second motor, and the brush roller to rotate synchronously. The two rotating brush rollers contact the front and back of the protective netting, moving up and down along the netting as they rotate. This effectively cleans the dust and impurities on the front and back of the netting, eliminating the need for manual cleaning and reducing the workload of workers, thus increasing the practicality of the equipment.

[0018] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0019] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 4 The present invention will be further described below.

[0020] This utility model discloses an adjustable mechanical safety guardrail device, including a first support column 1, a second support column 2, and a protective net 3 fixedly installed between the first support column 1 and the second support column 2. It also includes two brush rollers 4, with the protective net 3 located between the two brush rollers 4. A limiting groove 5 is opened on the side of the first support column 1 near the protective net 3. Two sets of angle adjustment components 6 are symmetrically arranged in the limiting groove 5, which respectively drive the two brush rollers 4 to rotate. A drive component 7 is arranged in the limiting groove 5 to drive the two sets of angle adjustment components 6 to rotate and reciprocate along the limiting groove 5. A lifting component 8 is provided at the bottom of both the first support column 1 and the second support column 2.

[0021] In this implementation scheme, when the protective net 3 needs to be cleaned, the two brush rollers 4 are initially located in the limiting groove 5. The two sets of angle adjustment components 6 drive the corresponding brush rollers 4 to rotate, so that the two brush rollers 4 rotate 90 degrees and come out of the limiting groove 5. The drive component 7 drives the two sets of angle adjustment components 6 to rotate and move back and forth along the limiting groove 5. The two sets of angle adjustment components 6 drive the brush rollers 4 to rotate. The rotating brush rollers 4 contact the front and back of the protective net 3 and move back and forth along the protective net 3. The rotating brush rollers 4 clean the dust and impurities on the protective net 3. When the cleaning is completed, the drive component 7 returns the two sets of angle adjustment components 6 to the initial state, and the two sets of angle adjustment components 6 rotate the two brush rollers 4 in the opposite direction by 90 degrees, so that the two brush rollers 4 enter the limiting groove 5.

[0022] Specifically, the drive assembly 7 includes a first motor 701, a reciprocating lead screw 702, and a slider 703. The first motor 701 is fixedly installed in the limiting groove 5. One end of the reciprocating lead screw 702 is fixedly connected to the output end of the first motor 701, and the other end is rotatably connected to the inner wall of the limiting groove 5. The slider 703 is sleeved on the lead screw and slides in cooperation with the limiting groove 5. The drive assembly 7 also includes two racks 704 and two gears 705. The two gears 705 are symmetrically rotatably connected to the slider 703, and the two racks 704 are symmetrically fixedly installed in the limiting groove 5. The two gears 705 mesh with the corresponding racks 704 respectively.

[0023] In this implementation scheme, when the protective net 3 needs to be cleaned, the first motor 701 is connected to an external power source and starts, driving the reciprocating screw 702 to rotate. Because the limit groove 5 limits the slider 703, the slider 703 moves up and down along the limit groove 5. At this time, the two gears 705 will rotate along the rack 704. The rotation of the two gears 705 drives the two sets of angle adjustment components 6 to rotate synchronously. When the cleaning is completed, the slider 703 moves to the bottom of the limit groove 5 and is in the initial position. The brush roller 4 does not contact the protective net 3.

[0024] Specifically, the angle adjustment component 6 includes a disc 601, two fixed blocks 602, a rotating rod 603, and a second motor 604. The disc 601 is fixedly mounted on the gear 705. The two fixed blocks 602 are symmetrically fixedly mounted on the disc 601. The second motor 604 is fixedly mounted on one of the two fixed blocks 602. One end of the rotating rod 603 is fixedly connected to the output end of the second motor 604, and the other end passes through the corresponding fixed block 602 and is rotatably connected to the other fixed block 602. The two brush rollers 4 are fixedly connected to the two rotating rods 603 respectively.

[0025] In this implementation scheme, when cleaning of the protective net 3 is required, the second motor 604 is an existing stepper motor, which will not be explained here. The second motor 604 is connected to an external power source, which will not affect the rotation of the second motor 604. The second motor 604 is started first, and the second motor 604 drives the rotating rod 603 to rotate. The rotating rod 603 drives the brush roller 4 to rotate 90 degrees, so that the brush roller 4 rotates out of the limiting groove 5. The two second motors 604 cause the two rotating rods 603 to rotate in opposite directions. When the gear 705 moves and rotates along the rack 704, the gear 705 drives the disc 601 and the two fixed blocks 602 to rotate. The rod 603 and the second motor 604 rotate synchronously with the brush roller 4. The rotating brush roller 4 contacts the protective net 3. The two brush rollers 4 rotate while moving up and down along the protective net 3. The two rotating brush rollers 4 clean the dust and impurities on the front and back of the protective net 3. When the cleaning is completed, the slider 703 moves to the bottom of the limiting groove 5, the first motor 701 is de-energized and returns to its initial position, and the brush roller 4 is no longer in contact with the protective net 3. At this time, the two second motors 604 drive the rotating rod 603 to rotate 90 degrees in the opposite direction, so that the two brush rollers 4 enter the limiting groove 5. At this time, the second motors 604 are de-energized.

[0026] Specifically, both sets of lifting components 8 include a connecting block 801, a base 802, and an electric push rod 803. The electric push rod 803 is fixedly installed inside the base 802. The output end of the electric push rod 803 is fixedly connected to the connecting block 801. The connecting block 801 is located directly above the base 802. The two connecting blocks 801 are fixedly connected to the bottom of the first support column 1 and the second support column 2, respectively.

[0027] In this implementation scheme, when it is necessary to adjust the height of the protective net 3 according to the height of the protective equipment, the electric push rod 803 is connected to an external power source. At this time, the electric push rod 803 is started and pushes the connecting block 801, which in turn drives the first support column 1 and the second support column 2 to rise and fall.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
