Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, and in particular to an adjustable-spacing lifting device. Background Technology

[0002] Lifting devices are mechanical equipment used for lifting and hoisting operations, and are widely used in industries, construction, logistics and transportation.

[0003] Currently, lifting devices using electric hoists are used to lift multiple objects simultaneously. Typically, multiple electric hoists are arranged side by side for synchronous lifting. However, we have found that the spacing between these arranged electric hoists is uncontrollable. When lifting different objects, some larger objects are prone to contact or even collisions. To address this, we have designed a lifting device with adjustable spacing. Utility Model Content

[0004] The purpose of this application is to provide an adjustable-spacing lifting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an adjustable-spacing lifting device, including a limiting frame, two hanging ears fixed to the top of the limiting frame, a fixed plate fixed inside the limiting frame, a plurality of guide plates equally spaced on the outer wall of the fixed plate, an electric hoist fixed to the outer wall of the guide plate, a plurality of guide rods fixed to the inner wall of the limiting frame, sliding holes for the guide rods to pass through on the guide plates, and a pushing mechanism for moving the guide plates installed on the fixed plate.

[0006] Preferably, the pushing mechanism includes a push plate driven by an electric push rod, the push plate having a plurality of symmetrically opened inclined slots, and a slide head adapted to the inclined slots being fixed on the guide plate.

[0007] Preferably, the outer wall of the fixed plate is provided with a protective component, which includes a protective plate. Connecting rods are fixed to both sides of the protective plate. Mounting openings are provided on both sides of the top of the push plate. The connecting rods are fixed within the corresponding mounting openings. The electric push rod is fixed to the outer wall of the fixed plate, located within the corresponding mounting opening, and its output shaft is fixed to the corresponding connecting rod. The protective plate has an L-shaped structure. The protective component includes connecting rods and a protective plate, with the connecting rods directly connected to the output end of the electric push rod. When the electric push rod drives the push plate downwards, and several electric hoists approach each other, the protective plate connected to the connecting rods moves downwards with the push plate, providing external protection for the electric hoists and offering a certain level of protection when not in use.

[0008] Preferably, the outer wall of the push plate is provided with mounting grooves on both sides, and a plurality of guide wheels are rotatably arranged in the mounting grooves. The guide wheels are slidably arranged with the inner wall of the limiting frame, and the sliding of the guide wheels in the limiting frame reduces friction.

[0009] Preferably, a controller is fixed to the top of the protective plate. The controller is electrically connected to both electric push rods. The controller is equipped with a remote control switch, which can remotely control the two electric push rods to work simultaneously.

[0010] Preferably, the tops of the plurality of inclined grooves are close to each other and the bottoms are far apart from each other.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this utility model, by employing a limit frame, hanging lugs, a fixing plate, a push plate, an electric hoist, a guide plate, a sliding head, and protective components, the electric push rod drives the push plate to move. Since the sliding head is located in the inclined groove, the inclined groove pushes the sliding head to move when the push plate moves. When the push plate moves upward, the electric hoists on the guide plates move away from each other; when the push plate moves downward, the electric hoists on the guide plates move closer to each other. This achieves the distance adjustment of the electric hoists, effectively solving the problems raised in the background art. It enables appropriate adjustment of the distance between multiple objects when lifting them, minimizing the problem of objects contacting or even colliding with each other during lifting.

[0013] In this utility model, the protective components include a connecting rod and a protective plate. The connecting rod is directly connected to the output end of the electric push rod. When the electric push rod drives the push plate to move down and several electric hoists approach each other, the protective plate connected to the connecting rod moves down with the push plate to provide external protection for the electric hoists. It also provides a certain degree of protection when not in use. Attached Figure Description

[0022] Example: Reference Figure 1-4 The adjustable-spacing lifting device shown includes a limiting frame 1. Two hanging ears 2 are fixed to the top of the limiting frame 1. The hanging ears 2 are fixed at a predetermined height by a tool. A fixing plate 3 is fixed inside the limiting frame 1. Several guide plates 6 are installed at equal intervals on the outer wall of the fixing plate 3. An electric hoist 5 is fixed to the outer wall of the guide plate 6. Several guide rods 10 are fixed to the inner wall of the limiting frame 1. The guide plate 6 has sliding holes 7 for the guide rods 10 to pass through. A pushing mechanism for moving the guide plate 6 is installed on the fixing plate 3.

[0023] With the above structure, the pushing mechanism includes a push plate 4 driven by an electric push rod 18, a plurality of inclined grooves 9 are symmetrically opened on the push plate 4, and a slide head 8 adapted to the inclined grooves 9 is fixed on the guide plate 6.

[0024] With the above structure: the outer wall of the fixed plate 3 is provided with a protective component 14, which includes a protective plate 17. Both sides of the protective plate 17 are fixed with connecting rods 16. The top two sides of the push plate 4 are provided with mounting holes 13. The connecting rods 16 are fixed in the corresponding mounting holes 13. The electric push rod 18 is fixed to the outer wall of the fixed plate 3. The electric push rod 18 is located in the corresponding mounting hole 13, and the output shaft of the electric push rod 18 is fixed to the corresponding connecting rod 16. The protective plate 17 has an L-shaped structure. The protective component 14 includes the connecting rod 16 and the protective plate 17. The connecting rod 16 is directly connected to the output end of the electric push rod 18. When the electric push rod 18 drives the push plate 4 to move down and several electric hoists 5 approach each other, the protective plate 17 connected by the connecting rod 16 moves down with the push plate 4 to provide external protection for the electric hoists 5. It provides a certain protective effect when not in use.

[0025] With the above structure, mounting grooves 11 are provided on both sides of the outer wall of the push plate 4. Several guide wheels 12 are rotatably arranged in the mounting grooves 11. The guide wheels 12 are slidably arranged with the inner wall of the limiting frame 1. The guide wheels 12 slide in the limiting frame 1 to reduce friction.

[0026] With the above structure: a controller 15 is fixed on the top of the protective plate 17. The controller 15 is electrically connected to both electric push rods 18. The controller 15 is equipped with a remote control switch, which can remotely control the two electric push rods 18 to work simultaneously.

[0027] With the above structure, the tops of several inclined grooves 9 are close to each other and the bottoms are far apart.

[0028] The working principle of this embodiment is as follows: By employing a limit frame 1, hanging lugs 2, fixing plate 3, push plate 4, electric hoist 5, guide plate 6, slider 8, and protective component 14, a remote control switch is used to control the electric push rod 18 via controller 15. This causes the electric push rod 18 to move the push plate 4. Since the slider 8 is located within the inclined groove 9, the inclined groove 9 pushes the slider 8 to move as the push plate 4 moves. When the push plate 4 moves upward, the electric hoists 5 on the guide plates 6 move away from each other; when the push plate 4 moves downward, the electric hoists 5 on the guide plates 6 move closer to each other. This achieves distance adjustment of the electric hoists 5, effectively solving the problems mentioned in the background technology. It allows for appropriate adjustment of the distance between multiple objects during lifting, minimizing contact or even collisions between the objects during lifting.
