DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] An embodiment of the present application provides a temporary enclosure guardrail for a deep foundation pit, which can solve the problem in the related art that the enclosure guardrail cannot be quickly arranged and carried, and protective measures cannot be immediately formed near the deep foundation pit, which increases the risk of the construction site.

[0032] See also Figure 1-Figure 3 A temporary guardrail for a deep foundation pit comprises: a main base 1 and at least two mobile bases 2, a blocking cable mechanism 3 is arranged between the main base 1 and the adjacent mobile base 2, and a plurality of fixing parts 12 are arranged on the main base 1 and the mobile base 2; the blocking cable mechanism 3 comprises a driving member 31, a rotating shaft 32, a plurality of unwinding drums 33 and a plurality of blocking cables 34, the rotating shaft 32 is rotatably arranged inside the main base 1, and a plurality of the unwinding drums 33 are sequentially arranged on the rotating shaft 32 along the height direction of the main base 1, the driving member 31 is connected to the rotating shaft 32 and is used to drive the rotating shaft 32 to rotate, the blocking cable 34 is wound around the unwinding drum 33, and one end of the blocking cable 34 is connected to the mobile base 2, wherein the main base 1 is hollow inside for accommodating the blocking cable mechanism 3.

[0033] The main base 1 is the core part of the entire enclosure guardrail, and is hollow inside to accommodate the blocking cable mechanism 3. This design not only makes the entire structure more compact, but also facilitates the arrangement and storage of the blocking cable mechanism 3. At least two mobile bases 2 are provided, which are used in conjunction with the main base 1. The design of the mobile base 2 allows the enclosure guardrail to be flexibly adjusted according to actual needs to adapt to deep foundation pits of different lengths and shapes.

[0034] The arresting cable mechanism 3 is a key part of the entire enclosure guardrail, which is used to realize the functions of rapid deployment and formation of protective measures.

[0035] The driving member 31 is connected to the rotating shaft 32, and the retracting and releasing action of the unwinding drum 33 is controlled by the rotation of the driving rotating shaft 32. This design makes the retracting and releasing of the blocking cable 34 simple and fast, and greatly improves the deployment speed.

[0036] The unwinding drum 33 is sequentially arranged on the rotating shaft 32 along the height direction of the main base 1, so that the barrier ropes 34 of different lengths can be retracted and released according to actual needs, and the number of barrier ropes 34 can be controlled at the same time to form a barrier net with different densities to adapt to different construction environments.

[0037] The blocking cable 34 is wound around the unwinding drum 33, and one end is connected to the mobile base 2. When the driving member 31 drives the rotating shaft 32 to rotate, the unwinding drum 33 releases or retracts the blocking cable 34, thereby forming an effective protective barrier between the main base 1 and the mobile base 2.

[0038] A plurality of fixing members 12 are provided on both the main base 1 and the mobile base 2. These fixing members 12 are used to fix the bases on the ground to ensure the stability and safety of the enclosure guardrail.

[0039] In summary, this temporary enclosure fence for deep foundation pits can be quickly deployed, carried easily, and immediately form protective measures through the ingenious design of the main base, mobile base, and blocking cable mechanism. In an emergency, it can quickly form an effective protective barrier near the deep foundation pit to ensure the safety of construction workers. At the same time, its flexible adjustment method and portability also enable it to play a good role in different construction environments.

[0040] like Figure 1 As shown, a clamping mechanism 4 is arranged between the main base 1 and the mobile base 2 in this embodiment; the clamping mechanism 4 includes a plurality of positioning rods 41, and the plurality of positioning rods 41 are arranged on the side of the mobile base 2 close to the main base 1, and a positioning groove 42 adapted to the positioning rod 41 is opened on the side of the main base 1 close to the mobile base 2.

[0041] During the transportation, the main base 1 and the mobile base 2 can be formed into a whole by clamping the positioning rod 41 with the corresponding positioning groove 42, so as to facilitate the handling and carrying of the staff.

[0042] In one embodiment, if Figure 1 and Figure 6 As shown, the two mobile bases 2 in this embodiment are arranged on two adjacent sides of the main base 1, and a clamping rod 5 is provided on one side of the mobile base 2 away from the main base 1, and a clamping groove 6 adapted to the clamping rod 5 is provided on the other side of the mobile base 2 away from the main base 1.

[0043] When it is necessary to set up a temporary enclosure guardrail around a deep foundation pit, two of the temporary enclosure guardrails are used together. First, one of the main bases 1 is placed at a predetermined position, and then a mobile base 2 is respectively set on the adjacent two sides of the main base 1. The two mobile bases 2 can adjust their positions according to actual needs to adapt to different foundation pit sizes and shapes. Then, the main base 1 and the mobile base 2 are fixed by the fixing member 12. Then, the other main base 1 is used to place the two main bases 1 diagonally, and then the matching mobile base 2 is placed close to the fixed mobile base 2, so that the clamping rod 5 on it is plugged into the corresponding clamping slot 6, thereby enclosing and forming a rectangular enclosure guardrail.

[0044] Through this design, a rectangular temporary enclosure guardrail can be quickly enclosed without complicated installation process, which greatly improves the construction efficiency. At the same time, its stability and safety are also effectively guaranteed, providing strong support for the safe construction of deep foundation pit projects.

[0045] In another embodiment, if Figure 7 As shown, the two mobile bases 2 in this embodiment are arranged relatively on the main base 1.

[0046] By relatively arranging two movable bases 2, a parallel and stable enclosure fence can be formed. Combined with the use of the blocking cable mechanism 3, it can effectively prevent people from mistakenly entering or approaching the deep foundation pit area, ensuring the safety of construction. This design is not only simple and practical, but also can be quickly arranged and removed to meet the needs of different construction environments.

[0047] like Figure 1 As shown, the main base 1 in this embodiment is embedded with a sleeve 7 adapted to the blocking cable 34, and one end of the blocking cable 34 passes through the sleeve 7 and is connected to the mobile base 2.

[0048] The design of the sleeve 7 facilitates the extension of the blocking cable 34 from the inside to the outside of the main base 1, while reducing the friction between the blocking cable 34 and the side wall of the main base 1, thereby increasing the service life.

[0049] It should be noted that if Figure 3 As shown, in this embodiment, the driving member 31 includes a driving motor 311 and a reducer 312 arranged inside the main base 1, the output shaft of the driving motor 311 is connected to the input shaft of the reducer 312, and the output shaft of the reducer 312 is connected to the corresponding rotating shaft 32.

[0050] The driving member 31 is a key component, which is responsible for providing power to the arresting cable mechanism 3 so that the arresting cable 34 can be quickly deployed or retracted.

[0051] In actual operation, the driving motor 311 is started, and its output shaft starts to rotate and is transmitted to the input shaft of the reducer 312. The main function of the reducer 312 is to reduce the rotation speed and increase the torque, so that the output shaft can have greater power when rotating while maintaining a stable rotation speed. Then, the rotational power adjusted by the reducer 312 is transmitted to its output shaft, which is directly connected to the rotating shaft 32. When the output shaft of the reducer 312 rotates, the rotating shaft 32 will also rotate accordingly. A number of unwinding drums 33 are arranged along the length direction of the rotating shaft 32. When the rotating shaft 32 rotates, the unwinding drum 33 will also rotate accordingly, thereby controlling the retraction and release of the blocking rope 34. Specifically, when the rotating shaft 32 rotates forward, the unwinding drum 33 will release the blocking rope 34 to extend it; when the rotating shaft 32 rotates reversely, the unwinding drum 33 will retract the blocking rope 34 to return it to its initial position.

[0052] It should be noted that after the blocking cable 34 is retracted and the main base 1 and the mobile base 2 are fixed by the fixing member 12, the driving motor 311 is turned on again, and the blocking cable 34 is driven to be retracted to a certain length through the reverse rotation of the rotating shaft 32, and then the driving motor is turned off, so that the blocking cable is in a taut state.

[0053] In this way, the driving member 31 can accurately control the retraction and extension of the blocking cable 34, thereby realizing the rapid deployment and removal of the guardrail. At the same time, due to the use of the reducer 312, it can be ensured that the output shaft has sufficient torque, so that the blocking cable 34 can remain stable when subjected to external forces, preventing people from crossing the guardrail.

[0054] In summary, the driving member 31 realizes precise control of the blocking cable mechanism 3 through the coordinated work of the driving motor 311 and the reducer 312, so that the entire guardrail can be quickly and stably arranged and removed as needed.

[0055] like Figure 1 and Figure 2 As shown, in this embodiment, the main base 1 is provided with a power supply 8, the main base 1 is provided with a controller 9, the controller 9 is electrically connected to the power supply 8, and the controller 9 is electrically connected to the drive motor 311.

[0056] The power supply 8 provided on the main base 1 provides power support for the entire enclosure guardrail system. The power supply 8 can be a rechargeable battery pack or other suitable power supply equipment to ensure normal operation even when there is no external power supply at the construction site.

[0057] The controller 9 is electrically connected to the power supply 8 and is used to control the power supply and logic operation of the entire system. The controller 9 can be a microprocessor or other intelligent control device with programming and logic judgment capabilities, and can control the action of the enclosure guardrail according to a preset program or external instructions. The controller 9 is also electrically connected to the drive motor 311 and drives the operation of the drive motor 311 by sending a control signal. When it is necessary to arrange or retract the blocking cable 34, the controller 9 will send a corresponding instruction to the drive motor 311.

[0058] In addition, it should be noted that in this embodiment, an external power supply can be used to power the device.

[0059] In this embodiment, in order to ensure the stable operation and continuous power supply of the temporary enclosure guardrail for deep foundation pits, an external power supply can be used to power the equipment. The external power supply usually refers to the existing power supply system at the construction site, such as a temporary power box, a generator or other stable power supply equipment. By using an external power supply, continuous and stable power support can be provided for the entire enclosure guardrail system, ensuring the normal operation of various components such as the controller, drive motor, and sound and light alarm.

[0060] like Figure 1 As shown, in this embodiment, the main base 1 is provided with an audible and visual alarm 13 , the audible and visual alarm 13 is electrically connected to the controller 9 , and a plurality of warning strips are provided on both the main base 1 and the mobile base 2 .

[0061] The controller 9 controls the sound and light alarm 13 to start. The sound and light alarm 13 is used to send sound and light signals under certain circumstances to remind construction workers or surrounding personnel to pay attention.

[0062] The sound and light alarm 13 emits a high-decibel alarm and eye-catching flashing lights, effectively attracting people's attention and reminding them to quickly take necessary measures or stay away from the dangerous area.

[0063] The purpose of setting warning strips is to further enhance the warning effect of the guardrail. These warning strips are usually made of eye-catching colors and obvious signs, such as reflective materials, so that they can be clearly seen during the day and at night. Warning strips can be marked with warning words such as "Be careful" and "Do not approach" to remind people to pay attention to the existence of the guardrail and comply with the corresponding safety regulations.

[0064] Through the dual functions of the sound and light alarm 13 and the warning strip, the temporary enclosure fence of the deep foundation pit not only provides a physical protective barrier, but also improves the safety of the construction site and reduces the probability of accidents through visual and auditory warnings. At the same time, this design also reflects the importance attached to the safety of construction workers and helps to create a safer and more efficient working environment.

[0065] like Figure 2 and 6 As shown in the figure, the present embodiment also includes a fastening mechanism 10, and the fastening mechanism 10 includes a plurality of sleeves 101, a screw rod 102 and a pressure plate 103. The sleeve 101 is arranged on the mobile base 2, and the sleeve 101 is located on the outside of the corresponding blocking cable 34. The screw rod 102 is threadedly connected to the sleeve 101, and the pressure plate 103 is located in the sleeve 101. One end of the screw rod 102 is connected to the pressure plate 103. A threaded groove matching the screw rod 102 is opened on the sleeve 101, and a knob is arranged at the other end of the screw rod 102.

[0066] In actual use, the screw rod 102 and the pressure plate 103 are rotated by rotation, and the threaded rotation thrust of the screw rod 102 drives the pressure plate 103 to squeeze the blocking cable 34, so that the blocking cable 34 is in a taut state.

[0067] like Figure 3 As shown, the fixing member 12 in this embodiment is a ground nail or a fastening bolt, wherein the main base and the mobile base 2 are provided with a plurality of through holes or threaded holes that are compatible with the fixing member 12 .

[0068] The selection of the fixings 12 is crucial to ensure the stability and safety of the entire structure. When ground nails are used as fixings 12, they are directly inserted into the soil to fix the main base 1 and the mobile base 2 by the friction of the soil. The ground nails are usually designed with a sharp head and sufficient length so that they can easily penetrate the soil layer and reach a sufficient fixing depth. This fixing method is simple and fast and is suitable for most soil conditions, especially for construction sites without hardened ground; on the other hand, when fastening bolts are used as fixings 12, they are usually used with pre-set reserved holes or mounting plates. By screwing the fastening bolts into the reserved holes or mounting plates, the main base 1 and the mobile base 2 can be firmly fixed. This fixing method is suitable for construction environments that already have hardened ground or have a specific installation foundation.

[0069] By properly selecting and using the fixing member 12, the temporary enclosure guardrail of the deep foundation pit in this embodiment can be firmly fixed on the ground, effectively preventing it from being blown by the wind or moved by humans, thereby ensuring the safety and stability of the construction site.

[0070] Preferably, Figure 3 As shown, in this embodiment, the barrier rope 34 is sleeved with a plurality of spike rings 11, wherein the spike ring 11 includes a semicircular tube and a plurality of spikes adapted to the barrier rope 34, the semicircular tube is sleeved on the barrier rope 34, and the plurality of spikes are irregularly distributed on the outer surface of the semicircular tube.

[0071] In the design of the temporary enclosure guardrail for deep foundation pits, in order to further increase its protective effect and safety, the present embodiment sleeves a plurality of spike rings 11 on the blocking cable 34. The spike rings 11 are uniquely designed, and their outer surfaces are covered with sharp thorns, which can effectively prevent people from climbing or crossing the blocking cable 34. When people try to touch or cross the blocking cable 34, the thorns on the spike rings 11 will have a stinging and deterrent effect, thereby forcing them to give up the behavior of climbing or crossing.

[0072] By sleeve-connecting the spike ring 11 on the barrier cable 34, not only the protection level of the enclosure guardrail is increased, but also its overall protection effect is improved. The arrangement of the spike ring 11 can be adjusted according to actual needs to ensure that sufficient protection is provided at key locations.

[0073] In addition, the material of the spike ring 11 is usually selected to be made of a strong and durable material to ensure that it can remain in good condition during long-term use.

[0074] As a preferred embodiment, the unwinding drum 33 and the sleeve 2 101 in this embodiment are made of insulating materials, the barrier rope 34 is a metal connecting rope, and the barrier rope 34 is connected to an external cable.

[0075] By providing a suitable voltage to the barrier cable 34, the entire barrier cable can be charged, thereby forming a power grid protection. When a person or object touches the charged barrier cable, it will be stimulated by the current, thereby playing an effective protective and warning role. This power grid protection design can effectively prevent people from accidentally or illegally entering the construction area, thereby improving the safety of the construction site.

[0076] It should be noted that in order to ensure the safety and effectiveness of power grid protection, the voltage provided to the barrier cable 34 must be strictly controlled. Too high a voltage may cause serious electric shock accidents, while too low a voltage may not provide effective protection. Therefore, in practical applications, it is necessary to select a suitable voltage value according to the specific construction environment and safety requirements, and take corresponding safety measures, such as setting warning signs, conducting regular safety inspections, etc., to ensure the reliability and safety of power grid protection.

[0077] In summary, this implementation scheme provides a more efficient and safe protection scheme for the temporary enclosure guardrail of deep foundation pits by using an unwinding drum and sleeve made of insulating materials, a blocking rope of a metal connecting rope, and connecting with an external cable to form a power grid protection. This design not only improves the safety of the construction site, but also reduces the possibility of accidents.
