Description

Technical Field

[0001] The utility model relates to the construction field of lifting installation, in particular to a lifting shackle which can be opened and locked by remote control. Background Art

[0002] Lifting shackles are widely used in equipment installation operations, and the most commonly used ones are D-type and bow-shaped shackles. Lifting shackles are usually assembled from two easily disassembled parts, such as a buckle body and a pin shaft. According to the assembly form of the pin shaft and the buckle body, lifting shackles can be divided into W-type threaded shackles and X-type nut shackles. Among them, the eye of the buckle body of the W-type threaded shackle is a through hole at one end, and the eye at the other end has an internal thread. The pin shaft has a shoulder at one end and an external thread at the other end. When in use, the pin shaft is reliably connected to the buckle body through the thread; the eye of the buckle body of the X-type nut shackle is a through hole at both ends, and the pin shaft has a shoulder at one end and an external thread at the other end. After the pin shaft passes through the two through holes of the buckle body, it is fixed to the buckle body with a hexagonal bolt and a cotter pin. The W-type threaded shackle is more widely used in lifting and hoisting operations because of its easy disassembly and assembly, stable connection, and high safety.

[0003] During the use of the lifting shackle, before the heavy object lifting operation, the wire rope, lifting lugs and other slings need to be placed in the buckle body, and then the pin shaft and the buckle body are installed together; after the lifting is in place, the pin shaft and the buckle body are disassembled and the sling is taken out. Currently, the installation and disassembly of the shackle needs to be done manually by workers.

[0004] When installing the columns and beams of steel structure workshops, the main steel pipes of transmission towers, angle steel, tower pieces and other equipment, after the hoisted objects are in place and docked at high altitude, the lifting shackles and wire ropes and other slings are usually still at a high height from the ground. In order to remove the shackles and slings, workers usually need to climb from the ground to high altitude and then manually remove them. Such facilities under construction usually do not have ladders. High-altitude demolition operations are not only labor-intensive and have high safety risks, but climbing up and down also takes a lot of time and reduces the overall construction efficiency.

[0005] At present, the automatic removal scheme of lifting shackles is basically in two forms: spring pin and electric screw translation pin. The spring pin scheme has unthreaded through holes at both ends of the shackle body. One end of the pin with a shoulder is covered with a compressed spring, and the other end is fixed with a round pin after passing through the eye of the shackle body. When the round pin is pulled out by manpower or motor, the pin moves out of the eye on one side of the shackle body under the action of the spring to complete the opening action. However, compared with the national standard X-shaped shackle structure, this form reduces the hexagonal nut fixing mechanism at one end of the pin, which increases the safety risk of accidental opening. The electric lead screw translation pin solution adopts a two-section long pin. One side of the pin shoulder is a lead screw mechanism, and the other side is a plain shaft without threads. The motor rotates the nut on the lead screw to translate the pin left and right, thereby realizing the opening and closing of the shackle. However, compared with W-type and X-type shackles, this solution has no threaded locking between the pin and the eye on one side of the buckle body, nor is it fixed with a round pin. It is only fixed by a single-sided motor lead screw mechanism, which poses a greater safety risk.

[0006] In order to solve the practical difficulties in the lifting and installation of steel structures, especially the disassembly and installation of shackles and the removal of slings at high altitude, it is very necessary to develop an electric lifting shackle that meets national standards, is safe, reliable, efficient and convenient, and can realize remote control opening and closing functions. Utility Model Content

[0007] The technical problem to be solved and the technical task proposed by the utility model are to improve and perfect the existing technical solutions, and provide a lifting shackle that can be opened and locked by remote control, so as to reduce the labor intensity of construction, reduce the risk of operation, save the time of lifting operation, improve the construction production efficiency, and effectively improve the convenience and safety of removing the lifting sling. To this end, the utility model adopts the following technical solutions.

[0008] A lifting shackle capable of being opened and locked by remote control, comprising an opening and closing mechanism, a shackle body, a driving mechanism, and a remote controller for wirelessly controlling the action of the driving mechanism, wherein the driving mechanism is connected to the opening and closing mechanism to drive the opening and closing mechanism;

[0009] The driving mechanism includes a motor and a driving member connected to the output shaft of the motor;

[0010] The opening and closing mechanism includes a follower engaged with a driving member, and a buckle rod driven by the follower to rotate and move axially, wherein the buckle rod can be threadedly connected to the buckle body; the buckle rod is located at the opening of the buckle body; the rotation and axial movement of the buckle rod realize the opening or closing of the buckle body, and when the buckle body is in a closed state, the buckle rod and the buckle body are locked by threads.

[0011] The threaded locking design between the buckle rod and the buckle body makes the connection more secure and less likely to loosen when the buckle body is in a closed state, thereby enhancing the load-bearing capacity and stability of the lifting shackle. Threads can be provided at the end of the buckle rod and / or the middle of the buckle rod, and screw holes matching the buckle rod threads can be provided on the buckle body to achieve threaded connection.

[0012] The opening and closing of the shackle is controlled by a remote control, and the user does not need to directly touch the shackle, which greatly improves the convenience and flexibility of use. This non-contact control method is especially suitable for those occasions that require remote operation or inconvenient direct contact. The built-in motor as the driving source can automatically complete the opening and closing of the shackle, reducing the tediousness and error rate of manual operation, making the use of the shackle more efficient and reliable. The opening and closing mechanism realizes the opening and closing of the shackle through the engagement of the follower and the driver and the axial movement of the buckle rod. It is not only compact in structure, but also can ensure the stability and reliability of the shackle during the opening and closing process.

[0013] The lifting shackle is controlled automatically through remote operation, so that the sling device at high altitude or inaccessible places can automatically detach from the suspended object; it not only reduces the burden of operators who need to climb up to operate in person, but also avoids the safety risks caused by high-altitude operations. Traditionally, operators need to manually climb up and perform heavy and dangerous labor such as unhooking and dismantling slings; the application of this lifting shackle has completely changed this situation, making these originally labor-intensive tasks easy and simple, greatly reducing the physical burden on operators. There are high safety risks in high-altitude operations and direct operation of disassembling and assembling slings. The remote operation and automatic control functions of the lifting shackle effectively reduce the time that operators are exposed to dangerous environments, reduce the risk of accidents caused by human operating errors or environmental factors, and thus improve the safety of the overall operation. The characteristics of automation and remote control enable this lifting shackle to respond quickly to operating instructions and complete the removal of slings. Compared with traditional manual operation methods, this greatly saves operation time and improves construction efficiency. Since this lifting shackle can significantly reduce labor intensity, reduce operation risks and save operation time, it can directly improve construction production efficiency. The construction team can complete the lifting task faster and reduce the time wasted on waiting or dealing with safety issues, thereby speeding up the progress of the project. The design of this lifting shackle fully considers the needs of actual construction, making the removal process of the sling more convenient and quick. At the same time, its automation and remote control functions also further enhance the safety of the removal process, providing a more reliable guarantee for the construction team.

[0014] The driving member can be a gear, or a worm gear or a worm wheel to achieve the drive.

[0015] As a preferred technical means: the driving mechanism also includes a seat body, in which the motor is arranged, the output shaft of the motor extends outward from the seat body, the output shaft is connected to a driving gear as a driving member, and the driving gear meshes with a driven gear as a driven member; the opening and closing mechanism is arranged below the seat body.

[0016] The opening and closing mechanism can be used to support the seat body, improving the compactness and stability of the structure; a motor is installed in the seat body to reduce interference and damage to it by external factors, and also reduce the safety risks caused by accidental touch or misoperation by personnel.

[0017] The driving gear can be located outside the seat body, so as to avoid the heat generated by the gear during operation from affecting the motor and other components located in the seat body, thus avoiding performance degradation or damage caused by overheating and extending the service life of the shackle.

[0018] As a preferred technical means: a remote control receiver, a motor controller and a battery for supplying power to the remote control receiver and the motor controller are arranged in the seat body, and the remote control receiver is connected with the remote controller by wireless communication.

[0019] The remote control receiver, motor controller and battery are integrated into the housing, reducing external connection wires and components, making the entire lifting shackle more compact and neat. All key components are concentrated in one unit, which is easy to maintain and replace, reducing maintenance costs and time. The built-in battery provides power for the remote control receiver and motor controller, without the need for external power supply, enhancing the independence and mobility of the equipment. At the same time, the heat-prone components such as the drive gear can be placed outside the housing, which helps to reduce the temperature inside the housing, protect the controller and battery from overheating damage, and improve the safety and reliability of the equipment.

[0020] As a preferred technical means: a shell is provided on the outside of the seat body, the driving gear is located on the outside of the seat body, the driving gear and the driven gear are covered with a protective cover, and the protective cover is connected to the shell.

[0021] The presence of the protective cover effectively prevents the operator or external objects from directly contacting the high-speed rotating driving gear and driven gear, thereby avoiding possible accidental injuries such as pinching and scratching. The combination of the protective cover and the shell also provides certain dustproof and waterproof functions, protects the internal gears and transmission mechanism from the erosion of the external environment, and prolongs the service life of the equipment. The addition of the shell and protective cover enhances the structural stability of the entire drive mechanism, making the equipment more stable and reliable during operation. The protective cover can also reduce the vibration and noise generated by the gear transmission to a certain extent, improving the operation quality of the equipment. The protective cover also prevents external impurities from entering the interior, reduces the damage to internal components caused by impurities, and reduces the maintenance frequency. The design of the shell and protective cover can take into account aesthetics, making the entire drive mechanism more neat and professional in appearance, and improving the overall image of the product.

[0022] As a preferred technical means: the buckle body is a "U"-shaped metal part, a first screw hole is opened at the left end of the buckle body, and a through hole matching the buckle rod is opened at the right end, and the first screw hole and the through hole are arranged opposite to each other; the left section of the buckle rod is a first threaded section with a thread matching the screw hole, the buckle rod is inserted into the through hole, and the buckle rod is driven by the driving mechanism to move axially while rotating, so that the first threaded section of the buckle rod is away from the first screw hole, or matches the first screw hole.

[0023] The threaded cooperation between the first screw hole and the first threaded section of the buckle rod provides a reliable connection mode. When the two are closely matched, a large locking force can be generated to ensure the stability of the connection.

[0024] The driving mechanism drives the buckle rod to rotate and move axially at the same time, thereby realizing precise control of the matching state between the buckle rod and the first screw hole; the control method is flexible and reliable, and can be adjusted according to different work requirements. The first threaded section of the buckle rod can be away from the first screw hole to achieve an unlocked or separated state; it can also be closely matched with the first screw hole to achieve a locked or connected state. This technical solution is adaptable to different working environments and working conditions, and can provide reliable connection and locking effects regardless of whether it is required to frequently connect and separate or to withstand large loads.

[0025] As a preferred technical means: the opening and closing mechanism also includes a tube sleeve which is sleeved on the buckle rod, and the tube sleeve is located on the right side of the buckle body; the tube sleeve and the buckle body are fixedly connected or detachably connected.

[0026] The sleeve provides support and guidance for the opening and closing mechanism, ensuring the stability of the lever during movement and rotation. This helps reduce deflection or damage caused by vibration or external forces, and improves the reliability of the entire opening and closing mechanism. The lever is protected by the sleeve to prevent bending or deformation of the lever, ensuring its normal working condition.

[0027] When the pipe sleeve and the buckle body are detachably connected, the pipe sleeve can be easily maintained and replaced without disassembling the entire opening and closing mechanism, thereby reducing assembly and maintenance costs and time and improving the maintainability of the equipment.

[0028] When a fixed connection is adopted between the pipe sleeve and the buckle body, the reliability of the connection is improved, and the fixed connection can be adopted by welding or other methods.

[0029] As an optimal technical means: the pipe sleeve and the buckle body are detachably connected; a raised shoulder is provided on the outer side of the right end of the buckle body, and a second screw hole concentric with the through hole is opened on the shoulder; an external thread is provided on the left end of the pipe sleeve, and the pipe sleeve is threadedly connected to the second screw hole of the shoulder through the external thread.

[0030] The threaded connection method allows the pipe sleeve to be quickly installed on the buckle body without complicated tools or cumbersome steps, which improves installation efficiency. Similarly, when the pipe sleeve needs to be removed, it can be separated by simply loosening the threads, which is convenient for subsequent maintenance, replacement or adjustment. The design of the shoulder and the left end of the pipe sleeve makes the entire connection structure compact and does not take up too much space, which is in line with the trend of miniaturization and integration of modern equipment. The threaded connection itself has a high connection strength, which can ensure that the pipe sleeve will not loosen or fall off due to vibration or external force during operation, ensuring the stability and reliability of the opening and closing mechanism.

[0031] As a preferred technical means: the right section of the buckle rod is a second threaded section with an external thread, one or more axial limit grooves are provided on the outer side of the second threaded section, and a second screw hole matching the second threaded section is provided on the right end of the pipe sleeve; the driven gear is hollow, and its inner ring is provided with a protruding limit block matching the limit groove, and the limit block is embedded in the limit groove.

[0032] By providing one or more axial limit grooves on the outer side of the second threaded section of the buckle rod and cooperating with the raised limit block provided on the inner ring of the driven gear, the accurate positioning and stable connection between the buckle rod and the driven gear are achieved, which can effectively prevent the relative displacement or loosening of the two during the rotation process, thereby enhancing the stability and reliability of the entire connection structure. The close cooperation between the limit groove and the limit block ensures the accurate positioning of the buckle rod in the driven gear and the accuracy of the rotational movement; reduces the error and vibration during the transmission process, and improves the accuracy and efficiency of the entire transmission system. During installation, quick connection can be achieved through a simple alignment operation, thereby simplifying the installation and disassembly process. By designing the limit block directly in the inner ring of the driven gear and cooperating with the limit groove of the buckle rod, the entire connection structure is made more compact and integrated, which helps to save space and makes the layout of the entire device or system more reasonable and efficient.

[0033] As a preferred technical means: three circumferentially evenly arranged limit grooves are provided on the outer side of the second threaded section; three limit blocks are provided on the inner ring of the driven gear; an annular groove is provided on the outer circumference of the right end of the pipe sleeve, and the driven gear is provided with a ring extending to the left; three limit columns are evenly spaced on the ring, and the limit columns penetrate the ring and are inserted into the annular groove to achieve axial positioning of the driven gear.

[0034] By providing three circumferentially evenly arranged limiting grooves on the outer side of the second threaded section and cooperating with three limiting blocks on the inner ring of the driven gear, the structure has good stability and high strength, thereby improving the reliability of the connection.

[0035] The limit column design on the collar allows the driven gear to be easily installed on the pipe sleeve, and the limit column is inserted into the annular groove to achieve axial positioning, which simplifies the assembly process and improves assembly efficiency. At the same time, when maintenance or replacement of parts is required, it can also be quickly and conveniently disassembled and installed, reducing maintenance costs and time. The combined effect of the limit groove, limit block, limit column and annular groove forms a stable support and positioning structure that can effectively resist various external forces and vibrations, ensuring that the connection between the driven gear and the pipe sleeve remains stable at all times, thereby improving operational stability and reliability.

[0036] As an optimal technical means: a raised limiting ring is provided in the middle of the buckle rod, the inner diameter of the right end of the pipe sleeve is smaller than that of the left end to form a first limiting portion that can offset the limiting ring; the inner diameter of the second screw hole of the buckle body is larger than the through hole to form a second limiting portion that can offset the limiting ring.

[0037] The design of the limit ring allows the buckle rod to be limited in both directions. On the one hand, the first limit part formed by the inner diameter of the right end of the sleeve being smaller than the left end can prevent the buckle rod from moving excessively to the right, ensuring that it works within the predetermined position; on the other hand, the second limit part formed by the inner diameter of the second screw hole on the buckle body being larger than the through hole limits the excessive movement of the buckle rod to the left. This two-way limit mechanism significantly enhances the stability of the entire structure. During the operation of the equipment, due to external factors such as vibration and impact, the traditional connection structure may become loose or even fall off. The cooperation between the limit ring and the first and second limit parts effectively prevents this from happening. Even under the action of external forces, the buckle rod can remain in the predetermined position, thereby ensuring the normal operation of the equipment. The design of the limit ring makes it easier to achieve precise positioning of the buckle rod during the assembly process. The operator only needs to insert the buckle rod into the sleeve to the appropriate position. The limit ring will naturally resist the first and second limit parts when the buckle rod moves left or right, thereby improving the accuracy and efficiency of assembly.

[0038] This technical solution achieves a stable connection effect through a simple design of a limiting ring and a limiting part, reducing manufacturing costs and difficulty. The limiting ring and the limiting part can determine the position and size of the limiting ring according to the length, diameter and force of the buckle rod, thereby ensuring the stability and reliability of the connection.

[0039] Beneficial effects: The lifting shackle of the utility model can realize remote operation, so that the shackle can automatically detach from the suspended object at high altitude, avoiding the operator's manual climbing to remove the hook and dismantle the sling, significantly reducing the construction labor intensity, reducing the operation risk, saving the lifting operation time, improving the construction production efficiency, and effectively improving the convenience and safety of dismantling the sling device. The threaded locking design between the buckle rod and the buckle body makes the connection more firm and not easy to loosen when the buckle body is in a closed state, thereby enhancing the load-bearing capacity and stability of the lifting shackle.

DETAILED DESCRIPTION

[0047] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings of the specification.

[0048] Embodiment 1:

[0049] See also Figure 1 to Figure 6 In this embodiment, a lifting shackle capable of realizing remote opening and closing functions is provided, which includes a driving mechanism, a remote controller, an opening and closing mechanism 9 and a buckle body 10. The driving mechanism is connected to the opening and closing mechanism 9, and the driving mechanism is arranged on the buckle body 10. At the same time, the remote controller is connected to the driving mechanism through a wireless signal and controls the driving mechanism to realize the function of the opening and closing mechanism 9 and the buckle body 10.

It is used for on-site operators to understand the current status; the motor controller 4 is provided with a PWM signal generation module, a circle counting module and a limit logic judgment module, so as to realize the control of the motor. The motor 2 is a stepping motor. Of course, a travel switch can also be set to realize the travel control of the buckle rod. When the buckle rod reaches the set travel, the motor controller controls the motor to stop rotating, thereby realizing the action control of the opening and closing mechanism.

[0052] A shell 7 is disposed on the outside of the seat body 1, and a protective cover 8 is disposed at the bottom of the shell 7. The shell 7 and the protective cover 8 protect the seat body 1 and the internal structure thereof.

[0053] The buckle body 10 is integrally forged, and its structure is similar to that of a D-type shackle, which is U-shaped. A first screw hole 101 is provided at the left end of the buckle body 10, and a through hole 102 is provided at the right end. A shoulder 103 is provided on one side of the through hole 102, and an internal thread is also provided on the inner wall of the shoulder 103.

[0054] The opening and closing mechanism 9 includes a pipe sleeve 91, which is made of stainless steel. An external thread is provided on the outer wall of the left end of the pipe sleeve 91. The pipe sleeve 91 is threadedly connected to the shoulder 103 through the external thread. The external thread is adapted to the internal thread of the inner wall of the shoulder 103, and the installation and fixation of the pipe sleeve 91 is achieved by threaded connection.

[0055] A buckle rod 93 is arranged inside the tube sleeve 91, wherein the buckle rod 93 includes a slide rod 931, the slide rod 931 is located in the through hole 102 and is slidably connected thereto, and the left section of the slide rod 931 is a first threaded section 932, and the first threaded section 932 is adapted to the first screw hole 101 on the buckle body 10. When closing, the slide rod 931 rotates and moves toward the first screw hole 101, and then the first threaded section 932 is screwed into the first screw hole 101 to achieve closing, otherwise, it is opened;

[0056] It should be noted that the remote control is a switch device, which is not shown in the drawings of this application. When in use, it is held in the hands of a person to control the shackle, and the principle of its remote control adopts the existing technology;

[0057] The right section of the slide bar 931 is a second threaded section 934. A limiting ring 933 is provided between the second threaded section 934 and the slide bar 931. The second threaded section 934 is threadedly connected to the internal thread provided on the inner wall of the sleeve 91. Moreover, three limiting grooves 935 are provided at equal intervals on the outer side of the second threaded section 934.

[0058] A driven gear 94 is provided on the side of the tube sleeve 91 away from the buckle body 10. The driven gear 94 can rotate relative to the tube sleeve 91. Moreover, an annular groove 92 is provided on the outer side wall of the tube sleeve 91 at the end where the driven gear 94 is installed. The annular groove 92 serves to limit the driven gear 94. Correspondingly, a collar 941 is provided on the driven gear 94. The collar 941 is sleeved on the annular groove 92, and three limiting columns 942 are evenly distributed on the collar 941. The limiting columns 942 penetrate the collar 941 and are located in the annular groove 92. The two cooperate to play a limiting role, so that the driven gear 94 can be axially limited while rotating.

[0059] The driven gear 94 is sleeved on the second threaded section 934 , and the inner wall of the driven gear 94 is provided with limit blocks 943 corresponding to three limit grooves 935 distributed at equal intervals. The limit blocks 943 are located in the limit grooves 935 , and the two are slidably connected.

[0060] It should be noted that the remote control receiver 5 realizes information transmission with the transmitter in the remote control of the ground operator, so that the high-altitude lifting shackle can receive the power on and off, opening or closing shackle instructions issued by the ground operator, and feedback the parameters such as the opening and closing status and power of the shackle to the remote control end for display. The transmitting and receiving devices used for remote control comply with the relevant safety standards for industrial remote control anti-interference and anti-false operation.

[0061] The working principle of the utility model lifting shackle is:

[0062] When receiving the closing command, the motor 2 rotates forward, the motor 2 drives the driving gear 3 to rotate, the driving gear 3 drives the driven gear 94 assembled on the stainless steel pipe sleeve 91 to rotate, and the driven gear 94 drives the second threaded segment 934 to rotate through the three raised limit blocks 943, that is, drives the entire buckle rod 93 to rotate. Since the buckle rod 93 is threadedly connected with the stainless steel pipe sleeve 91, the buckle rod 93 moves axially toward the buckle body 10 side, and the first threaded segment 932 of the buckle rod 93 is screwed into the first screw hole 101 of the buckle body 10. After reaching the position, the motor 2 stops automatically, completing the closing action of the buckle.

[0063] Similarly, when the motor 2 rotates in the reverse direction, the buckle rod 93 will move axially toward the side away from the buckle body 10 while rotating until the opening action of the buckle is completed.

[0064] When the lifting shackle of the utility model performs the closing or opening action, the matching form and action process of the shackle body 10 and the shackle rod 93 are completely similar to the closing or opening process of the national standard W-type shackle, except that the motor 2 replaces the manual operation. When closed, the limit ring 933 on the shackle rod 93 is in close contact with the side wall of the through hole 102 of the shackle body 10, and the first threaded section 932 on the shackle rod 93 is threadedly matched with the first screw hole 101 of the shackle body 10, and the sliding rod 931 in the middle bears the load of the sling.
