Description

Technical Field

[0001] The utility model relates to the technical field of steel structure safety poles, in particular to a safety pole. Background Art

[0002] During steel structure construction, high-altitude work on steel beams and columns is often necessary. However, there are often no safety harnesses available on steel beams. Therefore, a combination of safety poles and wire ropes is often used as a protective measure.

[0003] Chinese patent document CN219509259U discloses a safety pole and a safety rope connection device, which primarily includes a connecting rod, a safety pole, a safety rope, and a fixing. The safety pole and connecting rod are fixed at both ends. The connecting rod is mounted on a roof purlin, and a safety rope is pulled through the safety pole. The connecting rod, fixing, and safety pole together form a trough, through which the roof purlin is inserted, allowing the fixing and connecting rod to slide along the length of the roof purlin. This device overcomes the existing drawback of the difficulty in hoisting caused by the large number of safety poles and safety ropes required to be installed during large roof construction areas. This reduces the workload of post-construction dismantling and improves safety to a certain extent.

[0004] However, the aforementioned solution's clamp-type safety pole design is only suitable for H-beams and is incompatible with other cross-sectional shapes, such as box beams and truss webs. This significantly limits the device's versatility across various steel structure types. Actual steel structure construction often encounters a variety of beam cross-sectional shapes. If the device is incompatible with these beams, different safety features will need to be prepared for each beam type, increasing construction costs and complexity. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the limitation of the narrow application range of the clip-type safety pole in the prior art, thereby providing a safety pole.

[0006] In order to solve the above technical problems, the technical solutions of the present invention are as follows:

[0007] A safety upright pole comprises a safety clamp and an upright pole, wherein the upright pole is connected to the safety clamp, and the upright pole is used to connect a safety rope; the safety clamp has two symmetrically arranged clamping members, which can move closer to or farther away from each other so that the two clamping members can clamp or release a steel structure; a plurality of telescopic rods are respectively connected to the opposite surfaces of the two clamping members, and the plurality of telescopic rods independently extend and retract to form a clamping surface that matches the shape of the steel structure.

[0008] The safety pole provided by this utility model utilizes multiple independently retractable telescopic rods on the clamping member of the safety clamp. When clamping a steel beam, the multiple telescopic rods are compressed and extend to different states. The resulting clamping surface, which matches the shape of the steel structure, is well compatible with steel beams of various cross-sectional shapes. Whether circular, square, or other complex steel structures, the coordinated action of the multiple telescopic rods can achieve stable clamping. This makes the safety pole effective in a variety of construction environments, improves its versatility, and indirectly reduces construction costs and complexity.

[0009] Optionally, a plurality of the telescopic rods are arranged in a matrix on the opposite surfaces of the two clamping members. By arranging the plurality of telescopic rods in a matrix, the clamping member can apply force from multiple points simultaneously when in contact with the clamped steel structure, and the distribution of the clamping force is more uniform. Compared with the design of a single or a small number of clamping points, the matrix arrangement can more effectively avoid damage to the clamped steel structure due to excessive local force, and can also prevent the steel structure from slipping due to uneven force. In addition, the telescopic rods arranged in a matrix can disperse the stress generated during the clamping process to various parts, avoiding stress concentration in a certain point or area, thereby improving the reliability and durability of the entire clamping structure.

[0010] Optionally, the telescopic rod has a fixed section and a telescopic section, wherein the telescopic section is sleeved on the outer ring of the fixed section, and the top of the telescopic section is used to abut the steel structure. Through the cooperation of the telescopic section and the fixed section, the length of each telescopic rod on the clamping surface of the steel structure in different clamping states can be fed back in real time, and the abutment of different steel structures can be completed without replacing rods of different lengths, thereby improving the convenience of work. In addition, the cooperation between the telescopic section and the fixed section can also provide better stability. Because the telescopic section is sleeved on the outer ring of the fixed section, the contact area between the two is larger when under pressure, which can effectively disperse stress and reduce deformation and shaking of the rod.

[0011] Optionally, the telescopic rod is connected to a first elastic member, which has an elastic force that drives the telescopic rod to extend away from the clamping member. With the provision of the first elastic member, when the clamping member is required to clamp the steel structure, the steel structure can overcome the elastic force of the first elastic member and press the telescopic rod inward, thereby bringing the clamping members closer together and completing the clamping operation. After the operation is completed, the clamping members move away from each other, and the external force pressing on the ends of the steel structure gradually decreases until it disappears. The elastic force of the first elastic member automatically drives the telescopic rod to extend away from the clamping member, returning the clamping device to its initial state without any additional operation, ready for the next operation. This automatic reset feature makes operation more convenient and efficient. Furthermore, during the clamping process, the elastic force of the first elastic member can continuously act on the telescopic rod, ensuring that the clamping member always maintains a certain clamping force, preventing the clamped object from accidentally loosening. Furthermore, when the clamping device is subjected to external impact or vibration, the first elastic member can absorb some of the energy, reducing the impact on the clamped object and improving the stability of the clamping.

[0012] Optionally, the two clamping members are connected via a connecting seat, and an extension rod is connected to each of the two clamping members. The extension rod is slidably connected to the connecting seat, and the connecting seat has a self-locking structure for locking the extension rod. The clamping state of the two clamping members is locked by the self-locking structure. The two clamping members are connected via the connecting seat, and the extension rods on the clamping members are allowed to slide on the connecting seat, so that the entire device can be used to clamp objects of different sizes. In addition, the setting of the self-locking structure can lock the extension rod to achieve one-way sliding of the extension rod, thereby ensuring that the two clamping members remain stable in the clamping state and prevent accidental loosening.

[0013] Optionally, the upright is rotatably connected to the connecting base, with a gear fixedly connected to the bottom end of the upright. The extension rod includes a rack structure that meshes with the gear. Rotation of the upright drives the gear at the bottom end of the upright, which in turn meshes with the rack structure on the extension rod. This allows precise control of the sliding distance of the extension rod, and thus precisely adjusts the distance between the clamping members to accommodate a variety of different steel structure clamping conditions. Furthermore, the gear and rack structure offers high stability and durability, and its relatively simple structure makes it easy to maintain and service.

[0014] Optionally, the self-locking structure includes: a ratchet fixedly connected to the bottom end of the vertical rod and a pawl cooperating with the ratchet, the pawl being rotatably connected to the connecting seat, and a second elastic member connected to the pawl, the second elastic member having an elastic force that drives the pawl to deflect toward the ratchet. By configuring the ratchet, pawl, and second elastic member, when it is necessary to slide the extension rod a certain distance to achieve clamping of the clamping member, the vertical rod can be rotated to drive the gear and ratchet. During the clamping process, the pawl is continuously subjected to a deflection force from the second elastic member in the direction of the ratchet's rotation, and automatically engages with the tooth groove of the ratchet under the action of the deflection force, thereby achieving continuous self-locking of the ratchet. When the ratchet stops rotating, the clamping member is locked. When it is necessary to release the clamping member, the pawl can be manually disengaged from the ratchet to achieve unlocking. The entire self-locking process does not require any additional tools and can be achieved entirely by relying on the mechanical structure itself, which also makes it easier for the operator to operate. Moreover, during the self-locking process, the pawl always maintains close contact with the ratchet wheel by relying on the second elastic member, which also ensures the reliability of the self-locking function.

[0015] Optionally, a guide structure is provided between the connecting seat and the extension rod.

[0016] The guide structure ensures the accuracy of the extension rod's trajectory on the connector, ensuring it always follows the intended path during sliding. This also improves the accuracy of the rod's sliding distance. Furthermore, when the device is subjected to external vibrations or other forces, the guide structure helps the connector and extension rod maintain a relatively stable state, providing a certain degree of resistance.

[0017] Optionally, the connecting seat has a first groove extending along the sliding direction of the extension rod, and the extension rod is slidably inserted in the first groove.

[0018] The first groove on the connector provides a clear sliding direction for the extension rod, ensuring it always follows the intended path without noticeable deviation or wobble. Furthermore, the inner wall of the first groove provides all-around support for the extension rod. The design of the first groove reduces friction between the extension rod and the connector, ensuring smoother sliding.

[0019] Optionally, the extension rod has a second groove extending along its sliding direction, and the bent edge of the first groove is slidably inserted into the second groove.

[0020] By sliding the bent edge of the first groove into the second groove, an embedded structure is formed. This structure provides precise guidance for the extension rod's sliding, ensuring that the extension rod always moves in a specific direction during sliding. The combination of the groove and the bent edge creates a smoother sliding contact surface between the extension rod and the connector, making the extension rod slide more smoothly. In addition, the edge of the second groove acts as a barrier, preventing the extension rod from sliding off the connector even when subjected to large external forces or vibrations, ensuring the reliability and stability of the device.

[0035] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model.

[0037] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] like Figure 1As shown, the utility model provides a safety pole 2, including a safety clamp 1 and a pole 2, the pole 2 is connected to the safety clamp 1, and the pole 2 is used to connect a safety rope; the safety clamp 1 has two symmetrically arranged clamping members 3, the two clamping members 3 can approach or move away from each other so that the two clamping members 3 can clamp or release the steel structure; a plurality of telescopic rods 4 are respectively connected to the opposite surfaces of the two clamping members 3, and the plurality of telescopic rods 4 are independently extended to form a clamping surface that matches the shape of the steel structure.

[0040] The safety pole 2 is equipped with multiple independently extendable and retractable telescopic rods 4 on the clamping member 3 of the safety clamp 1. When clamping a steel beam, the various telescopic rods 4, under pressure, exhibit varying degrees of expansion and contraction, forming a clamping surface tailored to the shape of the steel structure. This allows for excellent compatibility with a wide variety of steel beam cross-sectional shapes. Whether circular, square, or other complex steel structures, the coordinated action of the multiple telescopic rods 4 ensures stable clamping. This design allows the safety pole 2 to fully function in a variety of construction environments, significantly improving its versatility while also indirectly reducing construction costs and complexity.

[0041] like Figure 1 As shown, in some embodiments of the present invention, a plurality of telescopic rods 4 are respectively arranged in a matrix on opposite surfaces of the two clamping members 3 .

[0042] Specifically, by arranging multiple telescopic rods 4 in a matrix, the clamping member 3 can simultaneously apply force from multiple points when in contact with the clamped steel structure, resulting in a more even distribution of the clamping force. Compared to designs with a single or limited number of clamping points, the matrix arrangement more effectively avoids damage to the clamped steel structure due to excessive localized force, while also preventing the steel structure from slipping due to uneven force. Furthermore, the matrix arrangement of telescopic rods 4 disperses the stress generated during the clamping process to various locations, preventing stress concentration in a single point or area, thereby improving the reliability and durability of the entire clamping structure.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the telescopic rod 4 has a fixed section and a telescopic section. The telescopic section is sleeved on the outer ring of the fixed section, and the top end of the telescopic section is used to abut against the steel structure.

[0044] Specifically, the coordination of the telescopic and fixed sections provides real-time feedback on the length of the telescopic rod 4 at each location on the clamping surface of the steel structure in different clamping states. This eliminates the need to replace rods of different lengths to achieve abutment against different steel structures, improving operational convenience. Furthermore, the coordination of the telescopic and fixed sections provides excellent stability. Because the telescopic section fits over the outer ring of the fixed section, the contact area between the two is large when subjected to pressure, effectively dispersing stress and reducing deformation and shaking of the rod.

[0045] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the telescopic rod 4 is connected to a first elastic member 5 , and the first elastic member 5 has an elastic force that drives the telescopic rod 4 to extend in a direction away from the clamping member 3 .

[0046] Specifically, through the provision of the first elastic member 5, when the clamping member 3 is required to clamp the steel structure, the steel structure can overcome the elastic force of the first elastic member 5 and press the telescopic rod 4 in, thereby bringing the clamping members 3 closer together and completing the clamping operation. After the operation is completed, the clamping members 3 move away from each other. The external force pressing on the two ends of the steel structure gradually decreases until it disappears. The elastic force of the first elastic member 5 automatically drives the telescopic rod 4 out in a direction away from the clamping member 3, and the clamping device can be restored to its initial state without additional operation, ready for the next operation. This automatic reset feature makes operation more convenient and efficient. In addition, during the clamping process, the elastic force of the first elastic member 5 can continuously act on the telescopic rod 4, so that the clamping member 3 always maintains a certain clamping force, which can prevent the clamped object from accidentally loosening. Moreover, when the clamping device is subjected to external impact or vibration, the first elastic member 5 can absorb some of the energy, reducing the impact on the clamped object and improving the stability of the clamping.

[0047] like Figure 1 and Figure 4 As shown, in some embodiments of the present invention, the two clamping members 3 are connected by a connecting seat 6, and an extension rod 7 is respectively connected to the two clamping members 3. The extension rod 7 is slidably connected to the connecting seat 6, and the connecting seat 6 has a self-locking structure 8 for locking the extension rod 7. The clamping state of the two clamping members 3 is locked by the self-locking structure 8.

[0048] Specifically, the two clamping members 3 are connected by a connecting base 6, and the extension rod 7 on the clamping member 3 is allowed to slide on the connecting base 6. This allows the entire device to clamp objects of different sizes. In addition, the provision of a self-locking structure 8 can lock the extension rod 7, thereby achieving one-way sliding of the extension rod 7, thereby ensuring that the two clamping members 3 remain stable in the clamped state and preventing accidental release.

[0049] like Figure 1 and Figure 5As shown, in some embodiments of the present invention, the upright pole 2 is rotatably connected to the connecting seat 6, the bottom end of the upright pole 2 is fixedly connected to a gear 9, and the extension rod 7 has a rack structure 10 that meshes with the gear 9.

[0050] Specifically, the rotation of the upright 2 drives the gear 9 at the bottom of the upright 2, which then engages with the rack structure 10 on the extension rod 7. This precisely controls the sliding distance of the extension rod 7, and thus precisely adjusts the distance between the clamping members 3 to meet the clamping requirements of various steel structures. Furthermore, the gear 9 and rack structure 10 provide a highly stable fit, offering excellent durability, and their relatively simple structure makes them easy to maintain and service.

[0051] like Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the self-locking structure 8 includes: a ratchet 11 fixedly connected to the bottom end of the vertical rod 2 and a pawl 12 cooperating with the ratchet 11, the pawl 12 is rotatably connected to the connecting seat 6, and a second elastic member 13 is connected to the ratchet 11, and the second elastic member 13 has an elastic force that drives the pawl 12 to deflect toward the ratchet 11.

[0052] Specifically, through the arrangement of the ratchet 11, the pawl 12, and the second elastic member 13, when it is necessary to slide the extension rod 7 a certain distance to achieve the clamping of the clamp 3, it is only necessary to rotate the vertical rod 2 to drive the gear 9 and the ratchet 11. During the clamping process of the clamp 3, the pawl 12 will continue to be subjected to the deflection force from the second elastic member 13 in the direction of rotation of the ratchet 11. Under the action of the deflection force, it will automatically snap into the tooth groove of the ratchet 11, thus completing the continuous self-locking of the ratchet 11. When the ratchet 11 stops rotating, the locking of the clamp 3 is completed. When it is necessary to release the clamp 3, it is only necessary to manually disengage the pawl 12 from the ratchet 11 to achieve unlocking. The entire self-locking process does not require the aid of any additional tools and can be achieved entirely by the action of the mechanical structure itself, which is also convenient for the operator to operate. In addition, during the self-locking process, the pawl 12 always maintains close contact with the ratchet 11 by relying on the second elastic member 13, which also ensures the reliability of the self-locking function.

[0053] like Figure 1 As shown, in some embodiments of the present invention, a guide structure is provided between the connecting seat 6 and the extension rod 7 .

[0054] Specifically, the guide structure ensures the accuracy of the movement trajectory of the extension rod 7 on the connecting base 6, ensuring that the extension rod 7 always moves along the predetermined path during the sliding process, thereby improving the accuracy of the sliding distance of the extension rod 7. In addition, when the device is subjected to external vibration or other external forces, the guide structure helps the connecting base 6 and the extension rod 7 maintain a relatively stable state, providing a certain degree of resistance to external forces.

[0055] like Figure 1 and Figure 7 As shown, in some embodiments of the present invention, the connecting seat 6 has a first groove 14 extending along the sliding direction of the extension rod 7 , and the extension rod 7 is slidably inserted into the first groove 14 .

[0056] Specifically, the first groove 14 provided on the connecting base 6 provides a clear sliding direction for the extension rod 7, ensuring that the extension rod 7 always moves along the predetermined path during the sliding process without noticeable deviation or shaking. In addition, the inner wall of the first groove 14 provides all-round support for the extension rod 7. The design of the first groove 14 can reduce the frictional resistance between the extension rod 7 and the connecting base 6, making the extension rod 7 slide more smoothly.

[0057] like Figure 1 、 Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the extension rod 7 has a second groove 15 extending along its sliding direction, and the bent edge of the first groove 14 is slidably inserted into the second groove 15 .

[0058] Specifically, by sliding the bent edge of the first groove 14 into the second groove 15, an embedded structure is formed. This structure provides precise guidance for the sliding of the extension rod 7, ensuring that the extension rod 7 always moves in a specific direction during the sliding process. The combination of the groove and the bent edge can make the sliding contact surface between the extension rod 7 and the connecting base 6 smoother, making the sliding of the extension rod 7 smoother. In addition, the edge of the second groove 15 can act as a barrier, so that even when subjected to large external forces or vibrations, the extension rod 7 is unlikely to slide off the connecting base 6, ensuring the reliability and stability of the device.

[0059] Working principle:

[0060] When the safety pole 2 is working, the pole 2 is manually rotated to drive the gear 9 at the bottom end of the pole 2 to rotate synchronously, wherein the gear 9 is engaged with the rack structure 10 on the extension rod 7, so that the sliding distance of the extension rod 7 can be accurately controlled, and then the distance between the clamping parts 3 can be accurately adjusted to achieve the clamping operation of the safety clamp 1. When clamping steel structures with various cross-sections, during the clamping process of the safety clamp 1, the steel structure can overcome the elastic force of the first elastic part 5 to press the multiple telescopic rods 4 in, thereby forming a clamping surface that matches the shape of the steel structure, so that the clamping parts 3 are close to each other and the clamping operation is completed. When steel beams with different cross-sections are clamped, the clamping surfaces formed by the multiple telescopic rods are different. See Figure 9 、 Figure 10 and Figure 11The connecting seat 6 at the bottom end of the safety upright 2 is provided with a self-locking structure 8, that is, a ratchet 11, a pawl 12 and a second elastic member 13 are provided. When the upright 2 rotates, the ratchet 11 will also rotate synchronously. During the clamping process of the clamping member 3, the pawl 12 will continue to be subjected to the deflection force from the second elastic member 13 toward the rotation direction of the ratchet 11, and will automatically be stuck in the tooth groove of the ratchet 11 under the action of the deflection force, thereby realizing the continuous self-locking of the ratchet 11. When the ratchet 11 stops rotating, the locking of the clamping member 3 is completed. When the clamping member 3 needs to be released, the pawl 12 can be manually disengaged from the ratchet 11 to achieve unlocking.

[0061] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
