Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a safety hook device. Background Art

[0002] In the concrete pouring operation of high arch dams, the traditional construction process is that the rear-unloading vehicle loads concrete from the mixing plant, transports it to the unloading platform on the dam top, and then unloads the concrete into the hanging tank through the rear-unloading method. The hanging tank is then lifted by a cable crane to the warehouse to complete the pouring.

[0003] However, most unloading platforms are located in dangerous environments with high edges. When unloading, rear-dumping vehicles suddenly unload the weight, which can easily cause the vehicle to overturn, posing a significant safety risk. Summary of the Invention

[0004] Based on this, it is necessary to provide a safety hook device to address the problem that rear-dump vehicles are prone to overturning when unloading.

[0005] A safety hook device, comprising:

[0006] A ground anchor assembly, comprising a restraining member and anchoring structures respectively provided at both ends of the restraining member along a first direction, wherein the anchoring structures are fixed in the ground, and the first direction is an extension direction of the restraining member;

[0007] a traction assembly, one end of which is slidably connected to the restraining member along a first direction;

[0008] The connecting assembly is detachably connected to the other end of the traction assembly, and the connecting assembly is used to be fixed on the vehicle.

[0009] Both ends of the restraint are pre-buried and fixed to the ground. Once the vehicle is parked on the unloading platform, the towing assembly is slid onto the restraint, positioning it directly in front of the vehicle. The other end of the towing assembly is then connected to the connecting assembly at the front of the vehicle. During unloading, the front end of the vehicle is connected to the ground anchor assembly via the towing assembly, effectively counteracting the overturning moment caused by the sudden unloading of the load. The anchoring action of the ground anchor assembly keeps the front end of the vehicle fixed to the ground, thus preventing the risk of the vehicle overturning due to high-edge overturning caused by a shift in the center of gravity and ensuring safety during unloading operations.

[0010] In one embodiment, the anchoring structure comprises:

[0011] Anchor hook, anchored in the ground;

[0012] An anchor plate, fixed on the anchor hook;

[0013] The fastener is fixed on the anchor plate, and both ends of the restraining member are fixedly connected to the fastener respectively.

[0014] The anchor hook penetrates deep into the ground, using soil friction and its own structure to achieve stable anchoring, and can withstand large tensile forces; the anchor plate is fixed on the anchor hook, increasing the force-bearing area, dispersing the tensile force, and preventing structural damage caused by local stress concentration; the fasteners tightly connect the restraint and the anchor plate to ensure the connection strength and stability of the entire ground anchor assembly.

[0015] In one embodiment, the fastener includes an annular segment and a straight segment fixed to the annular segment, and the straight segment is fixedly connected to the anchor plate.

[0016] The setting of the ring segment provides a flexible and stable connection space for the restraints, facilitates the rapid installation and disassembly of the restraints, and greatly improves the convenience of on-site operations and construction efficiency; the ring segment is fixedly connected to the anchor plate through a straight segment to construct a rigid force transmission path, which can directly and efficiently transmit the vehicle unloading tension borne by the ring segment to the anchor plate and underground anchor hook, avoiding force transmission loss caused by deformation of the connecting parts and ensuring the stability of the structure under high load conditions.

[0017] In one embodiment, the annular segments are respectively provided at both ends of the straight segment along the first direction;

[0018] The safety hook device includes a plurality of restraining members arranged along a first direction, and two ends of two adjacent restraining members close to each other are respectively connected to the annular segments at both ends of the straight segment in a one-to-one correspondence.

[0019] The unloading platform is used to park multiple vehicles simultaneously. To ensure sufficient anchoring, multiple restraints are used, each secured to the ground via anchoring structures at both ends. Ring segments are provided at each end of a straight segment along the first direction. The adjacent ends of two adjacent restraints are connected to the ring segments at either end of the straight segment in a one-to-one correspondence. This means that a single anchoring structure can simultaneously connect two restraints, reducing the number of anchoring structures and improving construction efficiency.

[0020] In one embodiment, the traction assembly includes a pull rope and a sleeve ring provided at one end of the pull rope, and the pull rope is sleeved on the restraint member through the sleeve ring.

[0021] The coupling ring, which is attached to the restraint, utilizes the ring structure to fit the restraint to achieve stable positioning, preventing the pull rope from slipping or shifting under load. It also provides a flexible and convenient installation interface, allowing operators to quickly insert the coupling ring into the restraint to complete the connection, significantly improving on-site assembly efficiency. Furthermore, this design allows the towing assembly to slide freely along the restraint, adapting to different vehicle parking positions and enhancing the versatility of the safety hook device.

[0022] In one embodiment, the traction assembly includes a hook, which is arranged at the other end of the pull rope away from the sleeve ring, and the hook is hooked with the connecting assembly.

[0023] The pull rope is hooked to the connection component at the front end of the vehicle through a hook, which greatly improves the efficiency of on-site operations. Operators do not need complex tools and only need to align the hook with the connection component at the front end of the vehicle to quickly complete the fastening. Compared with traditional bolt fixing methods, it significantly shortens the installation time.

[0024] In one embodiment, the hook is a mechanical locking hook, a quick-release hook or a rotating hook.

[0025] After the pull rope is hooked to the connecting component at the front end of the vehicle through the hook, the hook can also be locked to prevent it from being unhooked, further ensuring the safety of the vehicle.

[0026] In one embodiment, the connection assembly includes:

[0027] A safety hook, a connecting portion and two ears arranged at one end of the connecting portion, wherein one end of the connecting portion away from the ears is fixed to the vehicle, and the two ears are respectively provided with coaxially arranged circular holes;

[0028] A pin shaft passes through the two circular holes in sequence, and the other end of the traction assembly is detachably connected to the pin shaft;

[0029] A locking piece is fixed on one end of the pin shaft passing through the ear portion, and a radial dimension of the locking piece along the pin shaft is larger than a radial dimension of the circular hole.

[0030] The vehicle is a rear-dump vehicle, with the safety hook fixed to the bumper. A pin engages with two ears, making the connection and removal of the towing assembly quick and easy. The operator simply inserts the pin through the ears and secures the locking piece at the other end to quickly complete the installation. Once unloading is complete, the reverse operation allows for quick removal, significantly reducing vehicle loading and unloading preparation time.

[0031] In one embodiment, the safety hook device includes a slot structure, and the ground anchor assembly is arranged in the slot structure.

[0032] The ground anchor assembly is housed within a trough structure, which effectively protects it from vehicle damage, mechanical collisions, and concrete splash during construction. This extends the service life of components like the anchor hook and anchor plate, reducing maintenance costs. The traction assembly is also stored within the trough when not in use, preventing it from being damaged by the wheels of a rear-mounted vehicle when reversing.

[0033] In one embodiment, the trough structure is embedded in the ground, which prevents the raised structure from occupying the unloading platform space and reduces obstruction when the vehicle is traveling.

[0034] The safety hook device features a restraining element with both ends pre-buried and fixed to the ground. Once the vehicle is parked on the unloading platform, the towing assembly is slid onto the restraining element, positioning it directly in front of the vehicle. The other end of the towing assembly is then connected to the connecting assembly at the front of the vehicle. During unloading, the front end of the vehicle is connected to the ground anchor assembly via the towing assembly, effectively counteracting the overturning moment caused by the sudden unloading of the load. The anchoring action of the ground anchor assembly keeps the front end of the vehicle fixed to the ground, thus preventing the risk of the vehicle tipping over due to a shift in its center of gravity and ensuring safety during unloading operations.

[0046] In the concrete pouring operation of high arch dams, the traditional construction process is that the rear-unloading vehicle loads concrete from the mixing plant, transports it to the unloading platform on the dam top, and then unloads the concrete into the hanging tank through the rear-unloading method. The hanging tank is then lifted by a cable crane to the warehouse to complete the pouring.

[0047] However, most unloading platforms are located in dangerous environments with high edges. When unloading, rear-dumping vehicles suddenly unload the weight, which can easily cause the vehicle to overturn, posing a significant safety risk.

[0048] See Figure 1 and Figure 2 An embodiment of the present application provides a safety hook device, which includes a ground anchor assembly 100, a traction assembly 200, and a connecting assembly 300. The ground anchor assembly 100 includes a restraining member 110 and anchor structures 120 disposed at both ends of the restraining member 110 along a first direction, wherein the anchor structures 120 are fixed to the ground; one end of the traction assembly 200 is slidably connected to the restraining member 110 along the first direction; and the connecting assembly 300 is detachably connected to the other end of the traction assembly 200. The connecting assembly 300 is used to be fixed to the vehicle, and the first direction is the extension direction of the restraining member 110.

[0049] In this embodiment, both ends of the restraint 110 are pre-buried and fixed to the ground via anchoring structures 120. After the vehicle is parked on the unloading platform, the traction assembly 200 is slid onto the restraint 110, positioning it directly in front of the vehicle. The other end of the traction assembly 200 is then connected to the connection assembly 300 at the front end of the vehicle. When the vehicle is unloading, the front end of the vehicle is connected to the ground anchor assembly 100 via the traction assembly 200, effectively offsetting the overturning moment caused by the sudden unloading of the vehicle. The anchoring action of the ground anchor assembly 100 constrains the front end of the vehicle to the ground, thereby preventing the risk of the vehicle overturning due to high-edge overturning caused by a shift in the center of gravity and providing safety for the unloading operation.

[0050] The vehicle may also be a vehicle that is prone to overturning during other operations. Multiple traction assemblies 200 may be connected to the restraint 110. The traction assembly 200 is not only used to be fixed to the front end of the vehicle, but also can be selectively connected to either side of the vehicle according to the force applied when the vehicle overturns.

[0051] In some embodiments, combined Figure 3 The anchoring structure 120 includes an anchor hook 121, an anchor plate 122, and a fastener 123. The anchor hook 121 is anchored in the ground; the anchor plate 122 is fixed to the anchor hook 121; the fastener 123 is fixed to the anchor plate 122, and the two ends of the restraint 110 are fixedly connected to the two fasteners 123 respectively.

[0052] In this embodiment, the anchor hook 121 penetrates deep into the ground and uses the friction of the soil and its own structure to achieve stable anchoring, and can withstand large tensile forces; the anchor plate 122 is fixed on the anchor hook 121, which increases the force-bearing area, disperses the tensile force, and prevents structural damage caused by local stress concentration; the fastener 123 tightly connects the constraint 110 and the anchor plate 122 to ensure the connection strength and stability of the entire ground anchor assembly 100.

[0053] Specifically, there are multiple anchor hooks 121, and the multiple anchor hooks 121 are welded to the bottom of the anchor plate 122 at the same time to increase the stability of the anchor plate 122. The restraining member 110 is a steel wire rope.

[0054] In some embodiments, combined Figure 2 The fastener 123 includes an annular segment 1232 and a straight segment 1231 fixed to the annular segment 1232 , and the straight segment 1231 is fixedly connected to the anchor plate 122 .

[0055] In this embodiment, the provision of the annular segment 1232 provides a flexible and stable connection space for the restraint 110, facilitates the rapid installation and disassembly of the restraint 110, and greatly improves the convenience of on-site operation and construction efficiency; the annular segment 1232 is fixedly connected to the anchor plate through the straight segment 1231, constructing a rigid force transmission path, which can directly and efficiently transmit the vehicle unloading pulling force borne by the annular segment 1232 to the anchor plate and the underground anchor hook 121, avoiding force transmission loss caused by deformation of the connecting parts, and ensuring the stability of the structure under high load conditions.

[0056] Further, combined Figure 3 , annular segments 1232 are respectively provided at both ends of the straight segment 1231 along the first direction; the safety hook device includes a plurality of restraints 110 arranged along the first direction, and the two ends of two adjacent restraints 110 close to each other are respectively connected to the annular segments 1232 at both ends of the straight segment 1231 in a one-to-one correspondence.

[0057] In this embodiment, the unloading platform is used to simultaneously park multiple vehicles. To ensure sufficient anchoring, multiple restraining members 110 are provided, each of which is secured to the ground at both ends via anchor structures 120. In this case, annular segments 1232 are provided at each end of the straight segment 1231 along the first direction. The adjacent ends of two adjacent restraining members 110 are connected to the annular segments 1232 at both ends of the straight segment 1231 in a one-to-one correspondence. This means that a single anchor structure 120 can simultaneously connect two restraining members 110, thereby reducing the number of anchor structures 120 and improving construction efficiency.

[0058] Specifically, the fastener 123 is integrally formed from round steel, with an annular segment 1232 provided at each end of a straight segment 1231. This means that the fastener 123 is shaped like an "8," with the straight segment 1231 welded to the anchor plate so that the two annular segments 1232 can each be connected to the traction assembly 200. The annular segments 1232 can be circular, elliptical, or other irregular structures that smoothly transition from end to end.

[0059] In some embodiments, combined Figure 2 The traction assembly 200 includes a pull rope 210 and a sleeve ring 220 provided at one end of the pull rope 210 , and the pull rope 210 is sleeved on the restraint member 110 through the sleeve ring 220 .

[0060] In this embodiment, the connection method of the sleeve ring 220 being mounted on the restraining member 110 not only utilizes the close fit between the ring structure and the restraining member 110 to achieve stable positioning, preventing the pull rope 210 from slipping or deflecting during the load process, but also provides a flexible and convenient installation interface. The operator only needs to quickly insert the sleeve ring 220 into the restraining member 110 to complete the connection, greatly improving on-site assembly efficiency. In addition, this design allows the towing assembly 200 to slide freely along the restraining member 110, adapting to different vehicle parking positions and enhancing the versatility of the safety hook device.

[0061] Specifically, the towing assembly 200 includes a plurality of pull ropes 210 of varying lengths. One end of each pull rope 210 is looped onto the restraining member 110 via a collar 220, allowing each pull rope to slide freely along the restraining member 110. The different lengths of pull ropes 210 are adapted to accommodate vehicles of varying sizes. For example, a shorter pull rope 210 is used to connect a large vehicle after it is parked; a longer pull rope 210 is used to connect a small vehicle after it is parked.

[0062] In some other embodiments, the pull rope 210 is a chain structure or a connecting rod structure.

[0063] Furthermore, the traction assembly 200 includes a hook 230 , which is disposed at the other end of the pull rope 210 away from the sleeve ring 220 , and the hook 230 is hooked with the connection assembly 300 .

[0064] In this embodiment, the pull rope 210 is hooked to the connecting component 300 at the front end of the vehicle through the hook 230, which greatly improves the on-site operation efficiency. The operator does not need complicated tools, but only needs to align the hook 230 with the connecting component 300 at the front end of the vehicle to quickly complete the fastening. Compared with traditional bolt fixing methods, the installation time is significantly shortened.

[0065] Specifically, the hook 230 is a mechanical lock hook, a quick release hook or a rotating hook. After the pull rope 210 is hooked with the connecting assembly 300 at the front end of the vehicle through the hook 230, the hook 230 can also be locked to prevent it from being unhooked, thereby further ensuring vehicle safety.

[0066] In some embodiments, combined Figure 4 The connecting assembly 300 includes a safety hook 310, a pin 320 and a locking piece 330. The safety hook 310 includes a connecting portion 312 and two ears 311 arranged at one end of the connecting section. The end of the connecting portion 312 away from the ears 311 is fixed to the vehicle, and the two ears 311 are respectively provided with coaxially arranged circular holes; the pin 320 passes through the two circular holes in sequence, and the other end of the traction assembly 200 is detachably connected to the pin 320; the locking piece 330 is fixed to one end of the pin 320 passing through the ears 311, and the radial dimension of the locking piece 330 along the pin 320 is greater than the radial dimension of the circular hole.

[0067] In this embodiment, the vehicle is a rear-loading vehicle. Safety hook 310 is fixed to the vehicle's bumper. Pin 320 engages with two ears 311, making attachment and removal of towing assembly 200 quick and easy. The operator simply inserts pin 320 through ears 311 and secures locking member 330 to the other end of ears 311 for quick installation. After unloading, the reverse operation allows for rapid removal, significantly reducing vehicle loading and unloading preparation time.

[0068] Specifically, the locking member 330 can be a latch or a nut. The locking member 330 is fixed to the other end of the pin 320. The radial dimension of the locking member 330 along the pin 320 is larger than the radial dimension of the circular hole to prevent the pin 320 from falling out of the ear 311.

[0069] In some embodiments, the safety hook device includes a slot structure 400 , and the ground anchor assembly 100 is disposed in the slot structure 400 .

[0070] In this embodiment, the ground anchor assembly 100 is disposed within the trough structure 400. This trough structure 400 effectively protects the ground anchor assembly 100 from vehicle damage, mechanical collisions, or concrete splash during construction, thereby extending the service life of components such as the anchor hook 121 and anchor plate 122 and reducing maintenance costs. Furthermore, the traction assembly 200 is also placed within the trough structure 400 when not in use. This trough structure 400 prevents the traction assembly 200 from being damaged by the wheels of a rear-dump vehicle when reversing.

[0071] Specifically, the trough structure 400 is embedded in the ground.

[0072] In this embodiment, the trough structure 400 is embedded in the ground to prevent the raised structure from occupying the unloading platform space and reduce obstruction when the vehicle is driving.

[0073] The safety hook device of the present application pre-buries the anchor structure 120 by pouring concrete, and then connects the two ends of the restraint 110 to the anchor structure 120, and sets a trough structure 400 for the ground anchor assembly 100, and places the traction assembly 200 in the trough structure 400. The trough structure 400 protects the restraint 110 and the traction assembly 200 from being crushed and damaged by the rear-unloading vehicle; the traction assembly 200 can slide along the length direction of the restraint 110 to ensure the safety protection of different unloading parts of the rear-unloading vehicle; the connecting assembly 300 is welded to the car bumper. During the unloading process of the rear-unloading vehicle, the traction assembly 200 is connected to the connecting assembly 300 on the rear-unloading vehicle. The traction assembly 200 transmits the overturning force of the vehicle to the ground anchor assembly 100 to ensure the safety of unloading.

[0074] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
