Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lifting devices, in particular to a lifting device facilitating locking of profiles. BACKGROUND

[0002] The production of complete electrical equipment involves numerous complex and diversified profile processing and assembly processes, such as I-beams, angle steels, flat steels, H-beams, C-beams, L-beams, etc. Traditionally, the transfer operation of these profiles is generally carried out by the traditional method of directly hanging the profiles with ropes, i.e. the ropes are looped around and hold the profiles, and then the lifting equipment is used for lifting.

[0003] However, this transfer method has significant defects: due to the inherent limitations of rope binding, the profiles are difficult to maintain a stable posture during lifting, and are prone to collision due to shaking and rotation, and even cause the profiles to slip, not only damaging the profiles themselves, but also possibly causing serious production safety accidents and threatening personnel safety. Therefore, developing a lifting device that can conveniently and safely fix the profiles has become a key requirement to improve the safety and efficiency of profile transfer operations in the manufacturing process of complete equipment.

[0004] At present, there is no effective technical solution to the above problems. CONTENT OF THE INVENTION

[0042] Please refer to Figures 1-4 Some embodiments of the application provide a lifting device for locking profiles, comprising:

[0043] A bracket 1 is provided with a U-shaped groove 11 extending in a first horizontal direction;

[0044] A sliding block 2 is horizontally and slidably installed on the U-shaped groove 11, and the sliding direction is perpendicular to the first horizontal direction;

[0045] A connecting bracket 3 is installed on one side of the bracket 1;

[0046] A first light rod 4 penetrates the connecting bracket 3 and one side of the bracket 1, and is slidably installed on one side of the bracket 1, and one end is fixedly connected with the sliding block 2;

[0047] A first baffle 5 is fixed on the first light rod 4 and located between the connecting bracket 3 and the bracket 1;

[0048] A spring 6 is sleeved on the first light rod 4, and the two ends are respectively pressed against the first baffle 5 and the connecting bracket 3;

[0049] A locker 7 is used to lock or unlock the position of the sliding block 2 on the bracket 1;

[0050] A hanging assembly 8 is installed on the top of the bracket 1 and used to connect the hook of the crane.

[0051] Specifically, the bracket 1 is a basic component of the spreader, which can be welded by steel plates or be a casted piece. The U-shaped groove 11 on the bracket 1 is used to accommodate various shaped sections, such as I-beams, angle steels or H-beams.

[0052] More specifically, the sliding block 2 is used to press the sections and fix them in the U-shaped groove 11. The sliding block 2 can be made of steel or other high-strength materials. The bottom surface of the sliding block 2 can be designed to match the surface shape of the sections to increase the contact area and improve the clamping stability. The position of the sliding block 2 can be adjusted according to the number of sections carried in the U-shaped groove 11, so that different numbers of sections can be accommodated on the bracket 1 and adaptively pressed by the sliding block 2.

[0053] More specifically, the connecting bracket 3 is installed on the side of the bracket 1, which is used to support the first light rod 4 and the elastic member 6. The connecting bracket 3 can be fixed on the bracket 1 by bolts, welding or other methods. The connecting bracket 3 can be provided with a through hole for the first light rod 4 to pass through and slide.

[0054] More specifically, the first light rod 4 is used to transmit the movement of the sliding block 2 and the elastic force of the elastic member 6. The first light rod 4 can be made of steel, and the surface can be treated by chrome plating or other methods to improve wear resistance and corrosion resistance.

[0055] More specifically, the first stopper 5 is fixed on the first light rod 4 and located between the connecting bracket 3 and the bracket 1. The first stopper 5 is used as a support for the elastic member 6 to limit the compression stroke of the elastic member 6. The first stopper 5 can be fixed on the first light rod 4 by screws, welding or other methods. The elastic member 6 is used to provide a pre-tightening force, so that the sliding block 2 can adaptively and reliably press the sections. The elastic member 6 can be a compression spring, a disc spring or other elastic elements.

[0056] More specifically, the locker 7 can adopt a quick clamp 72, a bolt locking mechanism or other locking devices, which is used to fix the position of the sliding block 2 and prevent the sections from loosening or falling off during hoisting.

[0057] More specifically, the hanging assembly 8 is installed on the top of the bracket 1 and used to connect the hook of the crane. The hanging assembly 8 can include ear hooks, lifting eyes, shackles, slings and other components. The design of the hanging assembly 8 needs to meet the safety requirements of hoisting to ensure that the spreader and the sections can be safely and reliably hoisted.

[0058] More specifically, when using the hoist for locking profiles according to the embodiments of the present application, the worker first needs to pull the sliding block 2 apart by the first light pole 4, so that there is enough space in the U-shaped groove 11 for the profile to be placed in. After pulling the sliding block 2 apart, the position of the sliding block 2 can be temporarily locked by the locking device 7, and then the profile is placed in the U-shaped groove 11 of the bracket 1. Next, the sliding block 2 is reset by sliding under the elastic action of the elastic member 6 by operating the locking device 7 to unlock the sliding block 2, so that the sliding block 2 is close to the profile and self-adaptively presses the profile. During this process, the elastic member 6 is compressed to generate a pre-tightening force, which can ensure that the profile is reliably clamped. Thereafter, the worker operates the locking device 7 to lock the sliding block 2, so that the sliding block 2 tightly fixes the profile in the U-shaped groove 11. Finally, the hoist is connected with the hoisting equipment through the hanging assembly 8, and the hoisting operation of the profile can be performed.

[0059] The hoist for locking profiles according to the embodiments of the present application is provided with the sliding block 2 that is self-adaptively pressed against the profile under the cooperation of the elastic member 6 and the first light pole 4, and the position of the sliding block 2 is quickly locked by the locking device 7 to achieve quick fixing of the profile. The profile can be firmly fixed in the U-shaped groove 11 during hoisting to avoid the risk of profile shaking, rotating and sliding, and to ensure the safety and stability of hoisting. When the profile needs to be unloaded, the locking device 7 is operated in reverse to unlock the sliding block 2, so that the profile can be removed from the hoist. Therefore, the hoist for locking profiles according to the embodiments of the present application also has the advantage of convenient operation.

[0060] It should be noted that the profile hoisting process should use multiple hoists for locking profiles according to the embodiments of the present application to load and fix the profile at multiple positions.

[0061] In some preferred embodiments, the locking device 7 comprises:

[0062] The second light pole 71 is arranged in parallel with the first light pole 4 and is fixedly connected with the first light pole 4 through the first blocking piece 5.

[0063] The quick clamp 72 is installed on one side of the bracket 1 and is used to lock or unlock the second light pole 71 to lock or unlock the position of the sliding block 2 on the bracket 1.

[0064] Specifically, the second light pole 71 is arranged in parallel with the first light pole 4 and is connected through the first blocking piece 5, thereby ensuring synchronous movement of the two light poles. The quick clamp 72 is installed on the bracket 1 and is used to lock or unlock the second light pole 71 to fix or release the position of the sliding block 2.

[0065] More specifically, when the sliding block 2 needs to be locked, the operator operates the quick clamp 72, and the quick clamp 72 locks the second light rod 71. Since the first light rod 4 is fixedly connected with the sliding block 2, and the second light rod 71 is fixedly connected with the first light rod 4 through the first blocking piece 5, the position of the sliding block 2 is thus fixed, and the profile is reliably clamped between the bracket 1 and the sliding block 2. When the sliding block 2 needs to be unlocked, the operator operates the quick clamp 72, and the quick clamp 72 unlocks the second light rod 71. The sliding block 2 can slide in the U-shaped groove 11, facilitating the profile to be put in or taken out. Specifically, the elastic member 6 is always in a compressed state, providing a clamping force of the sliding block 2 towards the profile, ensuring that the sliding block 2 preliminarily presses the profile before being locked, and avoiding the profile from falling off.

[0066] More specifically, the lifting appliance for locking the profile of the embodiment of the present application adopts the locker 7 of the second light rod 71 and the quick clamp 72, which has the advantages of simple structure, convenient operation, and reliable locking, and can effectively solve the instability problem of the profile during lifting, ensuring the safety and efficiency of the profile lifting.

[0067] It should be noted that the second light rod 71 is preferably connected through the connecting bracket 3 and one side of the bracket 1.

[0068] In some preferred embodiments, the quick clamp 72 is a quick-lock type light axis fixed clamp.

[0069] Specifically, the quick-lock type light axis fixed clamp can realize quick locking and unlocking of the second light rod 71, making the operation more convenient and fast, thereby improving the response speed and operation efficiency of the locking mechanism. Compared with ordinary quick clamps 72, the quick-lock type light axis fixed clamp usually has the characteristics of compact structure, strong locking force, and convenient operation, and can more reliably fix the second light rod 71, thereby ensuring the reliability of the position locking of the sliding block 2 and improving the overall safety and working efficiency of the lifting appliance.

[0070] As a preferred embodiment, the quick-lock type light axis fixed clamp can include a clamping part and a locking handle. The clamping part has a through hole for accommodating the second light rod 71. The locking handle is connected with the clamping part, and by pulling the locking handle, the opening and clamping of the clamping part can be controlled, thereby realizing the locking or unlocking of the second light rod 71.

[0071] In some preferred embodiments, as shown in Figure 4 the first light rod 4 and the elastic member 6 are both two, and the two first light rods 4 are symmetrically arranged on both sides of the second light rod 71.

[0072] Specifically, when the sliding block 2 is subjected to the pressure of the elastic member 6, this embodiment can realize more uniform force on both sides, avoiding the situation that unilateral force is too large to cause the sliding block 2 to tilt or jam.

[0073] More specifically, the two first light rods 4 and elastic members 6 arranged symmetrically can provide balanced elastic support force, so that the sliding block 2 is uniformly stressed when sliding in the U-shaped groove 11, and the movement is stable and avoids the phenomenon of jamming. Therefore, the adoption of two first light rods 4 and elastic members 6 arranged symmetrically can improve the stability and locking reliability of the sliding of the sliding block 2, and further improve the stability and safety of the whole lifting appliance.

[0074] In some preferred embodiments, the second light rod 71 is hinged with a handle 73, and the connecting bracket 3 is provided with a clamping head 31 for temporarily hooking the handle 73.

[0075] Specifically, the operator can hold the handle 73, move the second light rod 71 by rotating the handle 73, and then adjust the position of the sliding block 2.

[0076] More specifically, the clamping head 31 is fixed on the connecting bracket 3 and corresponds to the position of the handle 73. The structure of the clamping head 31 can be a hook structure, which is convenient for the handle 73 to be hooked in and out.

[0077] More specifically, when it is necessary to temporarily fix the position of the sliding block 2, the operator can pull the handle 73 to a predetermined position, and then hook the handle 73 into the clamping head 31, and use the clamping head 31 to limit the handle 73, so as to realize the temporary fixing of the sliding block 2, without the need to temporarily fix the pulled sliding block 2 by the locking device 7, so that the position adjustment and locking operation of the sliding block 2 is more convenient and fast.

[0078] In some preferred embodiments, as shown in Figure 3 The sliding block 2 includes a sliding block 21, and one side of the sliding block 21 is fixedly connected with the first light rod 4.

[0079] The bracket 1 has a first T-shaped sliding groove 12 at the bottom of the U-shaped groove 11, and the sliding block 21 has a protruding portion 211 which is in sliding cooperation with the first T-shaped sliding groove 12.

[0080] Specifically, the sliding block 21 is in sliding cooperation with the protruding portion 211 through the first T-shaped sliding groove 12, so as to limit the sliding track of the sliding block 2, which can ensure that the sliding block 2 does not deviate during sliding, and ensures the reliability of the sliding block 2 to press the profile, and improves the reliability of the locking profile.

[0081] In some preferred embodiments, the sliding block 2 further includes a movable pressing block 22 which is detachably installed on the side of the sliding block 21 away from the first light rod 4.

[0082] Specifically, the movable pressing block 22 can be fixedly connected with the sliding block 21 by means of fasteners such as bolts, pins or buckles or by means of plug-in connection. The detachable design of the movable pressing block 22 makes the sliding pressing block 2 applicable to the clamping requirements of profiles of different thicknesses, shapes, and materials, thereby effectively improving the versatility of the profile locking hoist.

[0083] In some preferred embodiments, the profile locking hoist further comprises:

[0084] The fixed pressing block 13 is detachably mounted on the other side of the bracket 1 and located in the U-shaped groove 11.

[0085] Specifically, the fixed pressing block 13 is arranged opposite to the sliding pressing block 2 as an additional structural component. The detachable mounting of the fixed pressing block 13 allows it to be flexibly adjusted or replaced according to the specific size and shape of the profile to be lifted, so as to adapt to the fixing requirements of different specifications of profiles, thereby expanding the application scenarios and range of the profile locking hoist.

[0086] More specifically, the fixed pressing block 13 can be mounted on the bracket 1 by means of detachable fasteners such as bolts, pins or quick clamping mechanisms or by means of plug-in connection, and is located inside the U-shaped groove 11 to ensure that it can jointly act with the sliding pressing block 2 to form a clamping force on the profile to be lifted.

[0087] In some preferred embodiments, the elastic member 6 is a compression spring.

[0088] Specifically, the two ends of the compression spring are pressed against the first stopper 5 and the connecting bracket 3 respectively, so that the compression spring provides a pre-tightening force to ensure that the sliding pressing block 2 maintains a certain pressure when it is not locked.

[0089] More specifically, when the hoist is in operation, the compression spring provides a continuous pressure to maintain tension between the first stopper 5 and the connecting bracket 3. This tension is converted into a pre-pressure of the sliding pressing block 2, which helps to preliminarily fix the profile. The linear compression characteristic of the compression spring ensures that it can provide a relatively stable elastic force under different loads, thereby ensuring the reliability of the hoist.

[0090] In some preferred embodiments, the hanging assembly 8 comprises lifting lugs arranged at the top of both sides of the bracket 1 and lifting ropes hooked to the lifting lugs (not shown in the figure).

[0091] Specifically, the lifting lugs can be fixed to the top of both sides of the bracket 1 by welding. The lifting lugs can have a ring shape to facilitate the hooking of the lifting ropes.

[0092] More specifically, the sling can be selected from a steel wire rope, which has high strength and ensures the safety of hoisting. The two ends of the sling are connected with two lifting lugs respectively, and the middle part is used for connecting the crane hook. The lifting lugs are symmetrically arranged on both sides of the top of the bracket 1, so that the force of the sling is balanced, and the balance and stability of the lifting appliance during hoisting are ensured.

[0093] More specifically, the lifting appliance facilitating the locking of the profile of the embodiment of the present application realizes the connection of the lifting appliance and the crane hook by arranging the lifting lugs on both sides of the top of the bracket 1 and using the sling to hook the lifting lugs. The lifting lug serves as a special connecting component and provides a stable hanging point. Compared with directly arranging a hanging hole on the bracket 1 or using other connection methods, the lifting lug can disperse the force and improve the connection strength and reliability. The lifting lug is arranged at the top of both sides of the bracket 1, and this layout makes the force of the sling more balanced, which helps to maintain the balance and stability of the lifting appliance during hoisting and reduces the risk of shaking and tilting. The sling, as a general hoisting tool, can be used in cooperation with the lifting lug to conveniently and quickly realize the connection with the crane hook and ensure the safety of hanging.
