A highly stable mechanical equipment lifting and installation mechanism

Abstract

This utility model discloses a high-stability mechanical equipment lifting and installation mechanism, including a lifting device slidably installed outside a supporting beam. A motor-driven drive roller is rotatably installed inside the lifting device. A lifting steel rope driven by an internal winch is installed below the lifting device, and a lifting plate is fixedly installed at the bottom end of the lifting steel rope. Fixed hooks are installed at both ends of the lifting plate. A horizontally arranged stabilizing plate is installed below the lifting device, and the lifting steel rope slides through the stabilizing plate. This high-stability mechanical equipment lifting and installation mechanism utilizes the winch inside the lifting device to drive the extension and retraction of the lifting steel rope, thereby achieving the purpose of lifting goods. After lifting, when the lifting device moves horizontally, the lifting steel rope, under the inertia of the goods below, causes relative displacement between the stabilizing plate and the lifting device. At this time, the connecting rod compresses the shock-absorbing spring, which, in conjunction with the damper, achieves the purpose of shock absorption, thereby reducing the swaying of the goods below.

Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically a high-stability mechanical equipment hoisting and installation mechanism. Background Technology

[0002] When loading large machinery and equipment at the port, lifting equipment is required to hoist the machinery and equipment from the ground onto the cargo ship.

[0003] In the prior art, Chinese Patent Application No. CN202210209862.X discloses a mechanical equipment lifting frame, relating to the field of lifting equipment technology. It includes a lifting support, with a crossbeam fixedly connected to the top of the support, a cable at the bottom of the crossbeam, an auxiliary pull rod fixedly connected to the side of the support, a lubrication mechanism on the side of the cable, and a shock-absorbing pulley at the bottom of the support. Through the interaction of a button, a moving block, a tightening spring, a locking rod, a rotating block, a telescopic rod, and a hook, when lifting the mechanical equipment, pressing the button compresses the tightening spring via the moving block, causing the locking rod to move and the rotating block to become unrestricted. This allows the telescopic rod and hook to be removed from the support, providing auxiliary fixation for the mechanical equipment, improving its stability during lifting, preventing damage, and facilitating transportation.

[0004] Based on the above information, it can be seen that existing lifting devices generally use steel cable hoisting. However, in actual use, the equipment needs to move laterally after being lifted. The starting and stopping phases of lateral movement will generate a certain amount of inertia (and the mechanical equipment itself is heavy, so the inertia generated is also large). Under the action of inertia, it is easy to cause the whole body to sway. Summary of the Invention

[0005] The purpose of this invention is to provide a highly stable mechanical equipment lifting and installation mechanism to solve the problem of inertia affecting stability during lateral movement, as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-stability mechanical equipment lifting and installation mechanism, comprising a lifting device slidably installed outside a supporting beam, an active roller driven by a motor rotatably installed inside the lifting device, a lifting steel rope driven by an internal winch being provided below the lifting device, a lifting plate being fixedly installed at the bottom end of the lifting steel rope, and fixed hooks being installed at the left and right ends of the lifting plate; a horizontally arranged stabilizing plate being installed below the lifting device, with the lifting steel rope sliding through the stabilizing plate, and a shock-absorbing mechanism being provided between the stabilizing plate and the lifting device; an electric winding roller being installed at the middle position inside the lifting device, the electric winding roller being the same as the winch inside the lifting device, the two rotating synchronously, and an auxiliary steel rope being wound around the outside of the electric winding roller.

[0007] Preferably, the shock absorption mechanism includes a connecting rod rotatably installed between the lifting device and the stabilizing plate, and the connecting rod has an overall bent structure, so that the stabilizing plate drives the connecting rod to rotate accordingly when it moves.

[0008] Preferably, a shock-absorbing spring is installed between the inner side of the connecting rod and the outer surface of the lifting device, and a damper is fixedly installed on the upper surface of the stabilizing plate. The cooperation between the shock-absorbing spring and the damper achieves an effective shock absorption effect, thereby reducing the swaying of the cargo below.

[0009] Preferably, an abutment ball is fixedly installed at the top of the damper, and the abutment ball abuts against the lower surface of the lifting device.

[0010] Preferably, four stabilizing pull ropes are fixedly installed on the lower side of the auxiliary steel rope, and a connecting sleeve is fixedly installed at the bottom of the stabilizing pull ropes, so as to improve the stability of the hoisting steel rope during use by utilizing the tension of the connecting pull ropes (triangular structure).

[0011] Preferably, the connecting sleeve and the hoisting steel rope form a through-type up-and-down sliding structure, and fixing bolts are installed on the outside of the connecting sleeve to fix it.

[0012] Preferably, a transverse connecting rope is fixedly installed at the lower end of the auxiliary steel rope, and an auxiliary hook is fixedly installed at the bottom end of the connecting rope.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the high-stability mechanical equipment lifting and installation mechanism adopts a novel structural design, the specific details of which are as follows:

[0014] 1. The hoisting device uses a winch inside to drive the extension and retraction of the hoisting steel rope, thereby achieving the purpose of hoisting the goods. After hoisting, when the hoisting device moves horizontally, the hoisting steel rope causes the stabilizing plate and the hoisting device to have relative displacement due to the inertia of the goods below. At this time, the connecting rod squeezes the shock-absorbing spring, which, together with the damper, achieves the purpose of shock absorption, thereby reducing the swaying of the goods below.

[0015] 2. An electric winding roller is installed in the middle of the lifting device. The extension and retraction of the auxiliary steel rope is synchronously controlled by the electric winding roller (the auxiliary steel rope extends and retracts synchronously with the lifting steel rope). The stabilizing pull rope at the lower end of the auxiliary steel rope pulls the lifting steel rope, and the triangular structure is used to improve the stability of the lifting steel rope.

[0016] Furthermore, the stabilizing rope and the hoisting steel rope are connected by a connecting sleeve. By sliding the connecting sleeve outside the hoisting steel rope, the angle of the stabilizing rope is changed, thereby adjusting its tension on the hoisting steel rope.

[0017] Furthermore, connecting ropes and auxiliary hooks are installed below the auxiliary steel ropes, and the auxiliary hooks are used to lift the goods on both sides, thereby improving the connection stability between the device and the goods. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-4 To achieve vibration reduction during device translation, this embodiment provides the following technical solution, specifically: a lifting device 2 slidably installed outside the supporting beam 1; a motor-driven drive roller 3 rotatably installed inside the lifting device 2; a lifting steel rope 4 driven by an internal winch is installed below the lifting device 2; a lifting plate 5 is fixedly installed at the bottom of the lifting steel rope 4; fixed hooks 6 are installed at both ends of the lifting plate 5; a horizontally arranged stabilizing plate 7 is installed below the lifting device 2; the lifting steel rope 4 slides through the stabilizing plate 7; and a vibration damping mechanism is provided between the stabilizing plate 7 and the lifting device 2. The vibration damping mechanism includes a connecting rod 8 rotatably installed between the lifting device 2 and the stabilizing plate 7; the connecting rod 8 has a bent structure; a vibration damping spring 9 is installed between the inner side of the connecting rod 8 and the outer surface of the lifting device 2; a damper 10 is fixedly installed on the upper surface of the stabilizing plate 7; an abutment ball 11 is fixedly installed at the top of the damper 10; and the abutment ball 11 abuts against the lower surface of the lifting device 2.

[0027] When using the device, first turn on the winch inside the lifting device 2 to extend the lifting steel rope 4. Then, fix the fixing hook 6 on the side of the lifting plate 5 to the cargo. After fixing, turn on the winch inside the lifting device 2 again to wind up the lifting steel rope 4. The cargo (such as machinery) is lifted by winding up the lifting steel rope 4. When the cargo is lifted to the designated height, turn on the motor inside the lifting device 2 to drive the drive roller 3 to rotate. The friction between the drive roller 3 and the support beam 1 drives the lifting device 2 to move horizontally. During the process of moving from a stationary state to a moving state, the cargo maintains its own state due to its own inertia, thereby causing the hoisting steel rope 4 to move relative to the hoisting device 2. At this time, the hoisting steel rope 4 drives the stabilizing plate 7 to move synchronously. The stabilizing plate 7 drives the connecting rods 8 on the left and right sides to rotate. When the connecting rods 8 rotate, they compress the shock-absorbing springs 9. At the same time, the stabilizing plate 7 compresses the damper 10 above. By utilizing the cooperation between the damper 10 and the shock-absorbing springs 9, the purpose of shock absorption is achieved, thereby reducing the swaying of the cargo below (especially for the starting and stopping stages of the lateral movement of the hoisting device 2).

[0028] Example 2: Please refer to Figures 5-6 In order to improve the stability of the hoisting steel rope 4, this embodiment provides the following technical solution, which specifically discloses: an electric winding roller 12 is installed in the middle of the inner side of the hoisting device 2, and an auxiliary steel rope 13 is wound around the outside of the electric winding roller 12. Four stabilizing pull ropes 14 are fixedly installed on the lower side of the auxiliary steel rope 13, and a connecting sleeve 15 is fixedly installed at the bottom of the stabilizing pull rope 14. The connecting sleeve 15 and the hoisting steel rope 4 form a through-type upper and lower sliding structure, and a fixing bolt 16 is installed on the outside of the connecting sleeve 15 for fixing. A transverse connecting rope 17 is fixedly installed at the lower end of the auxiliary steel rope 13, and an auxiliary hook 18 is fixedly installed at the bottom of the connecting rope 17.

[0029] After securing the fixed hook 6 to the cargo, the auxiliary hook 18 is then secured to the cargo. The auxiliary hook 18, in conjunction with the connecting rope 17, can provide tension in more directions on the cargo, improving the stability of the cargo. During the hoisting process, the electric winding roller 12 is simultaneously activated, causing the auxiliary steel rope 13 to extend and retract synchronously (the auxiliary steel rope 13 extends and retracts synchronously with the hoisting steel rope 4). This allows the stabilizing pull rope 14 below the auxiliary steel rope 13 to provide tension to the hoisting steel rope 4, improving the stability of the hoisting steel rope 4 (the stabilizing pull rope 14 and the hoisting steel rope 4 form a triangular structure). Depending on the cargo requirements, before hoisting, the connecting sleeve 15 is slid up and down on the outside of the hoisting steel rope 4 to change the angle between the stabilizing pull rope 14 and the hoisting steel rope 4. Finally, the connecting sleeve 15 is secured using the fixing bolt 16.
