Description

Technical Field

[0001] This application relates to the field of construction hook technology, and in particular to a multifunctional safety hook assembly for high-altitude construction. Background Technology

[0002] Hooks, as a common connecting or load-bearing component, are widely used in various fields such as high-altitude operations, construction, and height protection. They are typically used to connect safety ropes, tool ropes, or other safety protection devices to ensure the safety of construction personnel or equipment. Common hook structures are mostly made of metal hooks, achieving temporary or semi-permanent fixing functions through connection with fixed objects.

[0003] Most existing hook structures are designed for use with ropes, hanging rings, or fixing holes, and their connection methods are mostly hook-and-loop or hole-and-pin connections, suitable for specific structural scenarios. However, during high-altitude construction, workers often need to fix hooks to various components of the building structure or scaffolding, such as square tubes, angle irons, round rods, and C-shaped steel. Because these components have varying cross-sectional shapes, existing hooks are difficult to match effectively, resulting in poor adaptability during use.

[0004] On the other hand, existing hook installation methods often rely on additional auxiliary components, such as bolt tightening and clasp clamping. These methods not only increase the difficulty of operation at heights, but also pose significant safety hazards due to the cumbersome installation process and unstable contact. Especially when the structural contact surfaces are mismatched, problems such as uneven loading, swaying, and slippage can easily occur after the hook is fixed, seriously affecting the stability of use and operational safety. Utility Model Content

[0005] To address the problems mentioned in the background art, such as poor versatility of hook structures, difficulty in matching with building metal components, complex installation and operation, unstable fixation, and insufficient safety, this application provides a multifunctional safety hook assembly for high-altitude construction.

[0006] The multifunctional safety hook assembly for high-altitude construction provided in this application adopts the following technical solution:

[0007] A multi-functional safety hook assembly for high-altitude construction includes:

[0008] The base has guide grooves symmetrically arranged at both ends, and the length direction of the guide grooves is consistent with the axial direction of the base;

[0009] The connector has two parts, which are respectively disposed at both ends of the base and slide in cooperation with the guide groove of the base. When moving, the two connectors are configured to move towards or away from each other along the axis of the base. The connectors have at least two mounting parts with different structures in the circumferential direction. The mounting parts are configured to be able to mount the connectors on different fixed objects.

[0010] The main hook is rotatably connected to the base. When any mounting part of the connector is fixed to a fixed object, the main hook can be positioned directly below that mounting part.

[0011] By adopting the above technical solution, connecting parts capable of moving in opposite directions or back to back are provided, and multiple mounting parts with different structures are set in the circumferential direction of the connecting parts. This allows the hook assembly to flexibly adapt to various shapes of fixing components such as square tubes, angle irons, round rods, and C-shaped steel, significantly improving the structural versatility and adaptability of the hook. The main hook can always be positioned directly below the mounting part, achieving stable suspension with consistent gravity direction, thus improving the reliability and safety of attachment during high-altitude operations.

[0012] Optionally, the base has a central hole, in which a lead screw is installed. The lead screw can rotate relative to the base. Both ends of the lead screw are provided with external threads, and the external threads at both ends are arranged in opposite directions. Two connecting parts are threadedly connected to both ends of the lead screw.

[0013] By adopting the above technical solution, the two ends of the lead screw are provided with external threads in opposite directions, and the two connecting parts are respectively threaded with the lead screw, realizing the effect of synchronously controlling the movement of the two connecting parts in opposite directions by rotating the lead screw. This structure can realize the rapid adjustment of the spacing between the connecting parts and improve the efficiency of on-site installation.

[0014] Optionally, end caps are installed at both ends of the base, and a limiting part is provided at the center of the base to achieve axial limiting of the two connecting parts through the end caps and the limiting part.

[0015] By adopting the above technical solution, the limit displacement of the connector along the axial direction can be effectively limited, preventing it from accidentally falling off or misaligning due to excessive thread rotation, thereby enhancing the safety and reliability of the overall structure.

[0016] Optionally, the two ends of the lead screw pass through the end caps and are rotatably connected to a bracket. The bracket has a U-shaped structure, and a bushing extends downward from the middle of the bracket. The upper end of the main hook is rotatably connected to the bushing.

[0017] By adopting the above technical solution, a hook support structure with rotation function is constructed to automatically align the direction of gravity in various installation states, thereby improving stability.

[0018] Optionally, the bushing sidewall is fitted with a locking screw for locking the main hook.

[0019] By adopting the above technical solution, the main hook is adjusted to the desired position and then locked to prevent the main hook from rotating during operation, so as to meet the needs of situations where the main hook does not need to rotate.

[0020] Optionally, the connector includes a connecting portion at a middle position, an extension portion integrally connected to the connecting portion and extending outward, and a mounting portion disposed at the end of the extension portion, wherein the extension portion slides in cooperation with the guide groove.

[0021] By adopting the above technical solution, the connector adopts an integral structural design consisting of a connecting part, an extension part and an installation part. The extension part slides with the guide groove, which not only ensures the smoothness and directional guidance of the connector's movement, but also ensures that the connector maintains a stable connection with the base during the adjustment process, making the connector safe and reliable.

[0022] Optionally, the number of mounting parts is four, namely a first mounting slot, a second mounting slot, a third mounting slot, and a mounting plate; wherein,

[0023] The first mounting groove is a U-shaped groove with an arc-shaped base;

[0024] The groove gap of the second mounting groove is smaller than the groove gap of the first mounting groove;

[0025] The third mounting slot is a U-shaped slot with a square base;

[0026] The mounting plate has mounting holes on its surface.

[0027] By adopting the above technical solution, the first mounting slot can be used to suspend it on circular or elliptical metal components, the second mounting slot can be used to suspend it on metal components such as angle iron and I-beams, and the third mounting slot can be used to match rectangular components such as square tubes and square steel. The mounting plate is used to directly fix the hook assembly with bolts. The structural design of multiple mounting parts can expand the application range of the hook assembly, significantly improve its versatility and rapid deployment capability, and is suitable for the diverse operational needs of components on construction sites, thus enhancing the adaptability and practicality of the equipment.

[0028] Optionally, a support block is fitted onto the extension of the connector, and the side of the support block near the base is curved.

[0029] By adopting the above technical solution, after the connector is moved to both ends of the base, the support block also moves to the end position, thereby reducing the distance between the support block and the mounting part, so as to limit the fixed object (square tube, angle iron, round rod, C-shaped steel, etc.), prevent the fixed object from falling off from the corresponding mounting part, play a role in stabilizing and limiting, and have the effect of preventing falling off.

[0030] Optionally, a recessed area is formed in the middle of the base, making the base have a structure that is thin in the middle and thick at both ends.

[0031] By adopting the above technical solution, in the initial state, the connector is in the middle position of the base. At this time, the designated mounting part on the connector can be suspended on a fixed object, such as suspending the mounting part on a square tube. Then, by rotating the screw, the two connectors can be moved in opposite directions. Since the base is a structure that is thick at both ends, when the connector moves to the end position, the distance between the mounting part and the base will gradually decrease until it is minimized. Then, with the support block, the fixed object is limited, thereby preventing the fixed object from detaching from the corresponding mounting part and playing the role of preventing detachment.

[0032] Optionally, the lead screw is provided with a screwing part at the center of both ends.

[0033] By adopting the above technical solution, the lead screw can be easily rotated using tools such as wrenches to achieve the effect of the two connecting parts moving in opposite directions or in opposite directions.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] This utility model improves the versatility of connecting parts by setting different installation parts on the connectors, making them suitable for use with various fixed objects such as square tubes, angle irons, round rods, and C-shaped steels. Furthermore, the structure of the base, which is narrow in the middle and thick at both ends, combined with the design of the support block, allows the connectors to be suspended on the designated fixed object, and the positions of the two connectors can be adjusted by rotating the screw rod to prevent them from falling off. It has the advantages of convenient operation and high safety. Attached Figure Description

[0044] The present application will be further described in detail below with reference to the accompanying drawings.

[0045] like Figure 1-6 As shown in the figure, this application discloses a multifunctional safety hook assembly for high-altitude construction, comprising:

[0046] The base 1 has guide grooves 103 symmetrically arranged at both ends. The length direction of the guide grooves 103 is consistent with the axial direction of the base 1. The number of guide grooves 103 is consistent with the number of extensions 402 on the connector 4. In this example, there are four extensions 402 on a single connector 4. Therefore, there are four guide grooves 103 at one end of the base 1. For ease of processing, the guide grooves 103 are arranged from the middle position near the base 1 to both ends.

[0047] Two connectors 4 are provided, each located at one end of the base 1 and slidingly engaged with the guide groove 103 of the base 1. When moving, the two connectors 4 are configured to move towards or away from each other along the axis of the base 1. At least two installation parts with different structures are provided in the circumferential direction of the connectors 4. The installation parts are configured to install the connectors 4 on different fixed objects. The fixed objects can be common steel structural components in building construction, such as square tubes, angle irons, round rods, and C-shaped steel. Connecting the connectors 4 to these steel structural components can replace the method of drilling holes in the wall or ground to install hooks when arranging hooks. This will not cause damage to the building surface and has the advantage of wide adaptability.

[0048] The main hook 8 is rotatably connected to the base 1. When any mounting part of the connector 4 is fixed to a fixed object, the main hook 8 can be located directly below that mounting part. That is, the main hook 8 is designed to rotate relative to the base 1. Furthermore, the main hook 8 can rotate relative to the connector 4. This ensures that the main hook 8 will not be affected by the connector 4 during use, regardless of which mounting part on the connector 4 is in use, and can always be in a suspended state, thus stabilizing the center of gravity.

[0049] Specifically, the base 1 has a central hole 104, and a lead screw 2 is installed in the central hole 104. The lead screw 2 can rotate relative to the base 1. Both ends of the lead screw 2 are provided with external threads 201, and the external threads 201 at both ends are arranged in opposite directions. Two connecting pieces 4 are respectively threaded to both ends of the lead screw 2. With this arrangement, when the lead screw 2 is rotated, the two connecting pieces 4 can move towards each other or away from each other, so as to achieve the effect of adjusting the position of the two connecting pieces 4 at the same time, which is convenient and quick. In this example, a screwing part 202 is provided at the center of both ends of the lead screw 2. More specifically, the screwing part 202 in this example is a blind hole with a hexagonal cross-section.

[0050] Specifically, end caps 3 are installed at both ends of the base 1, and a limiting part 101 is provided at the center of the base 1. The end caps 3 and the limiting part 101 are used to axially limit the two connecting parts 4 to prevent the connecting parts 4 from detaching from the base 1. In this example, the end caps 3 are bolted to both ends of the base 1, which not only limits the axial movement of the connecting parts 4, but also strengthens the base 1 to improve the structural stability of the base 1 and the entire hook assembly. This can prevent the problem of the guide groove 103 spacing from increasing or the base 1 from deforming during use.

[0051] Specifically, the two ends of the lead screw 2 pass through the end cap 3 and are rotatably connected to the bracket 5. The bracket 5 has a U-shaped structure, and the middle position of the bracket 5 extends downward to form a bushing 6. The upper end of the main hook 8 is rotatably connected in the bushing 6 to realize the installation and positioning of the main hook 8.

[0052] Specifically, the bushing 6 is equipped with a locking screw 7 for locking the main hook 8 on its side wall. The locking screw 7 can be tightened according to actual needs to meet different usage requirements.

[0053] Specifically, the connector 4 includes a connecting portion 401 at the middle position, an extension portion 402 integrally connected to the connecting portion 401 and extending outward, and a mounting portion disposed at the end of the extension portion 402. The connecting portion 401 is mainly used for connecting with the lead screw 2, and the extension portion 402 is slidably engaged with the guide groove 103. In this example, there are four mounting portions, namely a first mounting groove 403, a second mounting groove 404, a third mounting groove 405, and a mounting plate 406; wherein...

[0054] The first mounting groove 403 is a U-shaped groove with an arc-shaped root, used to suspend the first mounting groove 403 on a round rod with a circular or elliptical cross-section. The round rod serves as a fixed object and bears the load-bearing support function of the hook assembly. Since the root of the first mounting groove 403 has an arc-shaped structure, it can fit with the outer contour of the round rod to form a surface contact, thereby improving the contact stability and avoiding shaking or slippage caused by point contact.

[0055] The gap between the second mounting groove 404 and the first mounting groove 403 is smaller. The second mounting groove 404 is suitable for suspending metal components with small edge thickness, such as angle iron and I-beams. Due to its narrower groove width, it can fit tightly against the edge of the angle iron or I-beam, forming a stronger clamping force during the hanging process and avoiding problems such as loosening or slippage. At the same time, the structure of the second mounting groove 404 facilitates quick positioning and hanging on components with protruding edges or limited space, improving the ease of operation and structural matching stability in high-altitude construction environments.

[0056] The third mounting groove 405 is a U-shaped groove with a square base, which is suitable for metal components with rectangular cross-sections such as square pipes and square steel.

[0057] Mounting plate 406 has mounting holes on its surface, which can be used to directly fix the hook assembly to planar components such as walls, steel structure webs, and wooden beams and columns using fasteners such as bolts and screws. It is suitable for installation scenarios where it is inconvenient to hang the hook or where semi-permanent fixation is required.

[0058] The above-mentioned structural form allows construction personnel to flexibly choose the fixing method according to the site environment, which improves the applicability and stability of the hook assembly in different construction structures. Understandably, in practice, the shape and number of the installation part can also be flexibly designed according to actual needs, and no limitation is made here.

[0059] Specifically, a support block 9 is sleeved and installed at the extension 402 position of the connector 4. The side of the support block 9 near the base 1 is an arc surface. When the connector 4 moves along the axis of the base 1, the support block 9 also moves with the connector 4. Since the bottom of the support block 9 is an arc surface, it can avoid getting stuck during the movement.

[0060] Specifically, a recessed area 102 is formed in the middle of the base 1, making the base 1 have a structure that is thinner in the middle and thicker at both ends. This design is mainly to cooperate with the aforementioned support block 9 to prevent it from falling off. Specifically, in the initial state during operation, as shown... Figure 3As shown, both connectors 4 are positioned near the center of the base 1. At this point, the distance between the support block 9 and the mounting part is at its maximum, facilitating the suspension of the designated mounting part (e.g., the first mounting groove 403) on the metal rod, achieving a smooth suspension effect. Then, by rotating the lead screw 2, the two connectors 4 move in opposite directions, and the support block 9 moves towards the end of the base 1 along with the connectors 4. Since the base 1 is narrower in the middle and wider at both ends, when the connectors 4 reach the end, the distance between the support block 9 and the mounting part shrinks to its limit. In this limit state, the support block 9 can fit against the fixed object (or there is only a very small gap between it and the fixed object), preventing the fixed object from detaching from the mounting part, thus achieving an anti-falling effect. Furthermore, since both connectors 4 move to both ends of the base 1, the distance between the two connectors 4 increases, increasing the span acting on the fixed object and improving the stability of the hook assembly during operation.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
