Description

Technical Field

[0001] The invention belongs to the technical field of foundation pit protection, and in particular relates to a foundation pit protection device and a use method thereof. Background Art

[0002] Many engineering projects involve excavation of foundation pits during construction. These foundation pits are earthworks carefully excavated according to the precise location, elevation and specific dimensions of the foundation plane designed. As a temporary engineering measure, the core function of the foundation pit is to create a necessary working space for subsequent infrastructure construction work. Usually, the excavation depth of such foundation pits is about 5 meters. In view of this, in order to effectively prevent pedestrians from accidentally falling into the foundation pit and causing safety accidents, it is particularly important to configure special foundation pit protection devices, which aim to both provide protection and issue clear warnings to passers-by.

[0003] Existing pit protection devices are often designed to be bulky, which requires workers to expend a lot of physical strength when moving them to the designated location, and their flexibility is greatly reduced. In addition, these devices are generally not very stable and lack effective support structures, making them prone to displacement or tipping over under external forces. What's more serious is that at night or in low-light environments, they cannot provide sufficient warnings to passing vehicles and pedestrians, thereby increasing potential safety risks.

[0004] In order to solve the existing technical problems, a foundation pit protection device is proposed to solve the problems of poor flexibility, insufficient support and no early warning of the protection device. Summary of the invention

[0005] The purpose of the present invention is to provide a foundation pit protection device and a method of using the same to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a foundation pit protection device, comprising a base 1 and a base 2, a support rod 1 is installed on the base 1, a support rod 2 is installed on the base 2, a warning component is arranged on the top of the support rod 1 and the support rod 2, the support rod 1 and the support rod 2 are connected by a protective plate, a cross bar is installed below the warning component, a moving component is arranged below the cross bar, a support component is installed on the middle part of the side of the support rod 1 and the support rod 2 away from the protective plate, and a fixed component is arranged below the support component;

[0007] The warning component includes a warning light 1, a warning light 2, a rotating shaft, a solar panel, a rotating motor, a placement board and a flashing light strip;

[0008] A warning light one is fixedly installed on the top of the support pole one, a warning light two is fixedly installed on the top of the support pole two, a light sensor is arranged inside the warning light one, a rotating motor is fixedly installed on the top of the cross bar, a rotating shaft is installed on the output end of the rotating motor, a placement plate is installed through the rotating shaft, a plurality of solar panels are fixedly installed on the placement plate facing the direction of the warning light one, and a plurality of flashing light strips are arranged on a side of the protective plate away from the support pole one.

[0009] When it is necessary to protect the excavated foundation pit, after placing the foundation pit protection assembly vertically on the ground, workers can use their feet to press the moving assembly to extend the moving assembly and lift base one and base two off the ground. At this time, workers only need to push the protective device to complete the movement, saving manpower and greatly improving the flexibility of the protective device. After moving to the designated position, kick the moving assembly again, the moving assembly retracts, and base one and base two contact the ground. At this time, open the support assembly behind support rod one and support rod two to form a favorable support for the protective device, and use the fixing assembly to contact and fix it with the ground at multiple angles. In the face of complex terrain near the foundation pit, the angle length of the support assembly behind support rod one and support rod two and the fixing assembly are adaptively adjusted to complete effective support and avoid displacement or damage due to the lack of stable support and fixing structure under the influence of external forces or severe weather conditions.

[0010] When the installation is completed, the solar panels on the placement board can be used to make the warning light 1, warning light 2 and the flashing light strip on the protective plate glow at night, warning pedestrians not to approach the dangerous area, and preventing pedestrians and vehicles from mistakenly entering the foundation pit area due to poor night vision. At the same time, a light sensor is installed in the warning light 1 501 to control the rotation motor to drive the rotation shaft to rotate, so that the solar panel can always face the sun during the day, improve the efficiency of natural resource utilization, and turn on the warning light at night.

[0011] The present invention further illustrates that a rotating page 1 is fixedly installed below the support rod 1, a moving short rod is installed on the rotating page 1, a moving caster 1 is fixedly installed on the side of the moving short rod close to the support rod 1, a fixed rod is fixedly installed on the side of the moving short rod away from the support rod 1, a rotating page 2 is installed below the support rod 2, a moving long rod is installed on the rotating page 2, a moving caster 2 is fixedly installed on the side of the moving long rod close to the support rod 2, the moving long rod and the moving short rod are both arranged to be tilted upward, a reset rod 2, a limit rod and a movable rod are fixedly installed in sequence on the end of the moving long rod away from the moving support rod 2, a hook rod is rotatably installed on the movable rod, the limit rod is fitted with the side of the hook rod, a reset rod 1 is installed on the hook rod, the reset rod 1 and the reset rod 2 are connected by a spring, and a kick plate is fixedly installed on the side of the hook rod close to the moving long rod. When the worker places the protective device vertically on the ground, he steps on the moving long rod with his foot, and the moving long rod squeezes the moving short rod below to make it move downward. At the same time, the hook rod on the mobile long rod contacts the fixed rod on the mobile short rod when it moves downward. The hook rod will rotate along the circumference of the fixed rod near the tail of the fixed rod under the limit of the limit rod. At this time, the movement of the hook rod near the tail of the fixed rod will cause the hook rod to rotate along the movable rod, and the reset rod 1 above it drives the spring to stretch in the direction of the support rod 1. When the hook rod hooks the fixed rod, it returns to its initial state under the elastic force of the spring. At this time, the mobile caster 1 and the mobile caster 2 contact the ground, the base 1 and the base 2 are lifted off the ground, and the mobile long rod and the mobile short rod are fixed by the hook rod and the fixed rod in a parallel posture. At this time, the worker only needs to push the support rod 1 or the support rod 2 to complete the overall movement of the protective device, which is simple, convenient and flexible. When moving to the specified position, just kick the kick plate with your foot, and the end of the hook rod near the fixed rod moves in the direction of the support rod 2 to make it detach from the fixed rod, and returns to the initial state under the action of the spring. The whole process is standing operation, and the workers do not need to bend over, which greatly saves manpower and reduces labor intensity.

[0012] The present invention further states that the movable long rod is arranged above the movable short rod, the hook rod is in a "J" shape as a whole, and the hook rod is tilted upward on the side close to the movable short rod so that the hook rod can move along the circumference of the fixed rod toward the second support rod when moving downward, so as to complete the fixing of the movable long rod and the movable short rod. The tilted setting of the tail end of the hook rod can make the hook rod rotate around the movable rod, move along the circumference of the fixed rod, and smoothly hook the fixed rod, so as to complete the extension of the movable caster wheel 1 and the movable caster wheel 2.

[0013] The present invention further illustrates that a triangular support plate is fixedly installed on one side of the support rod one and the support rod two away from the protective plate, and a storage sleeve rod is rotatably installed on the triangular support plate, an I-shaped movable groove is provided inside the storage sleeve rod, and an extension rod is slidably installed in the I-shaped movable groove, and a clamping slot is provided on both sides of the storage sleeve rod parallel to the triangular support plate, and a rotating short rod and a short rod are installed through the end of the extension rod close to the triangular support plate, and the rotating short rod is rotatably installed with a rotating sleeve plate at both ends away from the extension rod, and the two rotating sleeve plates are provided with an extension arc slot and a reset slot at the circumference of one end close to the short rod, and the two rotating sleeve plates are provided with a circular hole at the end away from the rotating short rod, and a clamping rod is installed through the two circular holes, and a limiting hook rod is fixedly installed on the short rod. When the protective device moves to the designated position, pull the storage sleeves behind the support rods one and two respectively, so that the storage sleeves can be adaptively rotated around the triangular support plates according to the conditions of the target location, pull the extension rod out from the storage sleeve along the I-shaped moving groove, adjust the length of the extension rod according to the terrain near the foundation pit, and when pulling the extension rod, rotate the short rod to drive the rotating sleeve and the clamping rod to move along the clamping slots on both sides of the storage sleeve. At the same time, due to the hole position design of the clamping slots, the limiting hook rod will slide along the extension arc groove when the extension rod moves outward to ensure that its extension amount is visualized and controllable. When the extension rod moves to the target length, it can be fixed by using a fixing assembly to form a triangular protection with the support rods one, two and the ground, thereby enhancing the support strength and avoiding displacement or even damage due to external force impact or severe weather conditions. When recovery is required, move the extension rod to the bottom of the card slot, rotate the card rod to a larger angle so that the limit hook rod hooks the reset slot and releases the card state. At this time, just push the extension rod into the storage sleeve to complete the reset.

[0014] The present invention further illustrates that the two groups of support assemblies are arranged in parallel, a first receiving groove plate is fixedly installed below the first support rod, and a second receiving groove plate is fixedly installed below the second support rod. When the protective device needs to be moved or used, the support assembly can be retracted or taken out from the first and second receiving groove plates, thereby reducing the occupied area and avoiding damage to the support assembly.

[0015] The present invention further illustrates that the ends of the two extension rods away from the rotating sleeve are fixedly installed with T-shaped square plate 1, and the position perpendicular to the T-shaped square plate 1 is provided with T-shaped square plate 2, and the T-shaped square plate 1 and T-shaped square plate 2 are connected through a cross universal joint, and the end of the T-shaped square plate 2 away from the cross universal joint is fixedly installed with a connecting block, and a contact fixing plate is fixedly installed on the connecting block. After the length and angle adjustment of the support assembly is completed, the angle of the T-shaped square plate 1 and the T-shaped square plate 2 can be adjusted according to the on-site conditions near the foundation pit to adapt to the uneven ground and complex on-site construction conditions. It is fixed to the ground through the holes on the contact fixing plate.

[0016] The present invention further illustrates that the light sensor is electrically connected to the rotating motor, and the solar panel is electrically connected to the first warning light, the second warning light, the flashing light strip and the rotating motor.

[0017] The present invention further illustrates that two splicing T-blocks are provided on the side of the support rod 1 away from the moving assembly, and two splicing U-blocks are provided on the side of the support rod 2 away from the moving assembly. The splicing of the protective device can be completed by using the splicing U-blocks and splicing T-blocks provided on both sides of the protective device, which can meet the protection requirements of foundation pits of different sizes.

[0018] The present invention further illustrates that the protective assembly is placed vertically on the ground, and the foot steps on the movable long rod, which drives the hook rod and the movable short rod to move downward, and the movable caster 1 and the movable caster 2 are pushed out. At this time, the base 1 and the base 2 leave the ground, and the worker can freely move the protective device. When moving to the target position, the worker kicks the kick plate with the foot to reset the movable long rod and the movable short rod; the supporting assembly behind the support rod 1 and the support rod 2 is pulled, and the length and angle of the extension rod are adjusted to match the complex terrain near the foundation pit, and the fixed assembly is fixed to the ground to complete the assembly.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. A moving component is provided. By stepping on the moving long rod, the moving long rod drives the hook rod to move downward. When the moving long rod moves, it squeezes the moving short rod to make it move downward. At the same time, after the hook rod hooks the fixed rod, the moving caster 1 and the moving caster 2 are extended, and the protective device is lifted off the ground. At this time, the worker only needs to push the support rod 1 or the support rod 2 to complete the overall movement of the protective device. It is simple, convenient and flexible. When moving to the designated position, just kick the kick plate with your foot, the hook rod moves backward to separate from the fixed rod, and returns to the initial state under the action of the spring. The whole process is standing operation, and the workers do not need to bend over, which greatly saves manpower and reduces labor intensity.

[0021] 2. A support component is provided, and the length of the extension rod can be flexibly adjusted according to the terrain near the foundation pit. When the extension rod is pulled, the rotating short rod drives the rotating sleeve and the clamping rod to move along the clamping slots on both sides of the storage sleeve. When the extension rod moves to the target length, it can be fixed by using the fixing component to form a triangular protection with the support rod one, the support rod two and the ground, thereby enhancing the support strength and avoiding displacement or even damage due to external force impact or severe weather conditions.

At this time, the worker only needs to push the protection device to complete the movement, saving manpower and greatly improving the flexibility of the protection device. After moving to the designated position, kick the moving assembly 8 again, the moving assembly 8 retracts, the base 1 and the base 2 2 contact the ground, and at this time, open the support assembly 9 behind the support rod 1 3 and the support rod 2 4 to form a favorable support for the protective device, and use the fixing assembly 12 to contact and fix with the ground at multiple angles. In the face of the complex terrain near the foundation pit, the angle length of the support assembly behind the support rod 1 3 and the support rod 2 4 and the fixing assembly 12 are adaptively adjusted to complete effective support, so as to avoid displacement or damage due to the lack of a stable support and fixing structure under the influence of external forces or bad weather conditions. When the installation is completed, the solar panel 504 on the placement plate 506 can make the warning light 1 501, the warning light 2 502 and the flashing light strip 507 on the protective plate 6 glow at night, warning pedestrians not to approach the dangerous area, and avoiding pedestrians and vehicles from mistakenly entering the foundation pit area due to poor night vision. At the same time, a light sensor is installed in the warning light 501 to control the rotating motor 505 to drive the rotating shaft 503 to rotate, so that the solar panel 504 can always face the sunlight during the day, improve the utilization efficiency of natural resources, and turn on the warning light at night.

[0036] The moving assembly 8 includes a rotating page 1 801, a rotating page 2 802, a moving caster 1 803, a moving caster 2 804, a moving short rod 805, a moving long rod 806, a spring 807, a kick plate 808, a hook rod 809, a movable rod 810, a limiting rod 811, a reset rod 1 812, a reset rod 2 813 and a fixed rod 814.

[0044] The working principle of the present invention is as follows: first, after the worker places the protective device vertically on the ground, he steps on the moving long rod 806, and the moving long rod 806 drives the hook rod 809 to move downward, and the moving long rod 806 squeezes the moving short rod 805 to move downward. At the same time, after the hook rod 809 contacts the fixed rod 814, it will rotate along the circumference of the fixed rod 814 under the restriction of the limit rod 811, so that the hook rod 809 hooks the fixed rod 814. At this time, the spring 807 is stretched and reset after the hook rod 809 is hooked with the fixed rod 814, so that the moving long rod 806 and the moving short rod 805 are fixed in a parallel posture. At this time, the moving caster 1 803 and the moving caster 2 804 contact the ground, and the base 1 1 and the base 2 2 are lifted off the ground. At this time, the worker only needs to push the support rod 1 3 or the support rod 2 4 to complete the overall movement of the protective device, which is simple, convenient and flexible. When it moves to the designated position, the kick plate 808 can be kicked by the foot, and the hook rod 809 moves backward to separate from the fixed rod 814 and returns to the initial state under the action of the spring 807. The whole process is operated standing up, and the worker does not need to bend down, which greatly saves manpower and reduces labor intensity.

[0045] When the protective device moves to the designated position, the storage sleeve 902 behind the support rod 1 3 and the support rod 2 4 are pulled respectively, so that the storage sleeve 902 can be adaptively rotated around the triangular support plate 901 according to the target location, and the extension rod 903 is pulled out from the storage sleeve 902 along the I-shaped moving groove 912, and the length of the extension rod 903 is adjusted according to the terrain near the foundation pit. When the extension rod 903 is pulled, the rotating short rod 905 drives the rotating sleeve 906 and the clamping rod 909 to move along the clamping slots on both sides of the storage sleeve 902. 904 moves, and at the same time, due to the hole design of the positioning slot 904, the limiting hook rod 911 will slide along the extension arc groove 907 when the extension rod 903 moves outward to ensure that its extension amount is visualized and controllable. When the extension rod 903 moves to the target length, it can be fixed by the fixing component 12, so that it can form a triangular protection with the support rod 1 3, the support rod 2 4 and the ground to enhance the support strength and avoid displacement or even damage under the impact of external forces or bad weather conditions. When it is necessary to recycle, the extension rod 903 is moved to the bottom of the positioning slot 904, and the clamping rod 909 is rotated at a larger angle so that the limiting hook rod 911 hooks the reset slot 908 to release the clamping state. At this time, it is only necessary to push the extension rod 903 into the storage sleeve rod 902 to complete the reset.

[0046] After the length and angle of the support assembly 9 are adjusted, the angles of the T-shaped square plate 1 1201 and the T-shaped square plate 2 1202 can be adjusted according to the site conditions near the foundation pit to adapt to the uneven ground and complex construction conditions on site. The fixing plate 1205 is fixed to the ground through the holes on the contact fixing plate 1205.
