Description

Technical Field

[0001] This utility model belongs to the field of hoisting, specifically a formwork hoisting tool for beam yards. Background Technology

[0002] When working at ports, construction sites, beam yards, or large steel plants, you may encounter situations where large materials or beam yard formwork need to be moved. In such cases, hoisting is required, and the main tools for hoisting include slings and lifting equipment.

[0003] Lifting equipment plays a very important role in lifting tools because large materials and beam yard formwork are heavy and numerous, so the strength of the lifting equipment and its stability during the lifting process are very important.

[0004] In existing technologies, when using lifting devices, the device is installed at the end of the rope, then attached to the equipment to be lifted, and the rope is tightened to lift the equipment. During the tightening process, the rope may swing or vibrate, which can cause the device to loosen between itself and the equipment being lifted, posing a safety hazard.

[0005] Therefore, this utility model provides a formwork lifting device for beam yards. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A beam yard formwork lifting device of this utility model includes a crossbeam; a lifting ring is fixedly connected to the top of the crossbeam; L-shaped side beams are fixedly connected to both ends of the crossbeam; a second bracket is fixedly connected to the side wall of the lifting ring; a bolt 13 is installed on the top of the second bracket 15; a nut 14 is installed at the end of the bolt 13; a first bracket 12 is hinged to the bolt 13; a second limiting ring is fixedly connected to the side wall of the first bracket; a first spring is fixedly connected to the inner side wall of the second limiting ring; the first spring is circumferentially distributed on the inner side wall of the second limiting ring; a first limiting ring is fixedly connected to the end of the first spring; the first and second limiting rings are arranged in multiple sets on the first bracket; the arrangement of the first limiting ring and the first spring effectively limits the swaying of the wire rope during the lifting process due to tightening, thus improving the safety of the working process.

[0008] Preferably, the inner wall of the first limiting ring is embedded with balls; the balls are distributed in multiple groups around the inner wall of the first limiting ring; by adding balls inside the first limiting ring, the wire rope can contact the balls when swinging inside the first limiting ring, thereby converting sliding friction into rolling friction, greatly reducing friction, improving the service life of the wire rope, and reducing the risk of operation.

[0009] Preferably, a second fixing block is fixedly connected to the side wall of the crossbeam; a second spring is fixedly connected to the top of the second fixing block; a third fixing block is fixedly connected to the end of the second spring; the third fixing block is fixedly connected to the side wall of the first support; a first fixing block is fixedly connected to the side wall of the crossbeam; a third spring is fixedly connected to the top of the first fixing block; and the end of the third spring is fixedly connected to the second limiting ring. The hinged design prevents damage to the first support under the immense tension of the wire rope, providing a certain amount of room for movement. The second spring's connection to the first support restricts the movement of the first support, further limiting the swing of the wire rope and making the entire lifting process more stable.

[0010] Preferably, a permanent magnet alloy is inserted at the turning point of the L-shaped side beam; a handle is fixedly connected to the end of the permanent magnet alloy; by setting the permanent magnet alloy, the square hole can be sealed, effectively preventing debris from entering, and it can be taken out when the square hole is needed for lifting, which is simple in structure and convenient in operation.

[0011] Preferably, a sealing ring is fixed to the end of the permanent magnet alloy; the sealing ring is arranged around the four sides of the permanent magnet alloy; by setting the sealing ring, liquid can be effectively prevented from flowing into the square hole and corroding the inside of the square hole, thus extending the service life of the lifting device.

[0012] Preferably, a fixing plate is fixed to the side wall of the permanent magnet alloy; a spring plate is fixed to the top of the fixing plate; the spring plates are symmetrically arranged at the top and bottom of the fixing plate; the arrangement of the spring plates allows the permanent magnet alloy to be more firmly and stably fixed to the square hole, making it less likely to detach.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The beam yard formwork lifting device described in this utility model effectively limits the swaying of the wire rope during the lifting process due to tightening by setting a first limiting ring and a No. 1 spring, thereby improving the safety of the working process.

[0015] 2. The beam yard formwork lifting device of this utility model, by adding ball bearings inside the first limiting ring, allows the wire rope to contact the ball bearings when swinging inside the first limiting ring, thereby converting sliding friction into rolling friction, greatly reducing friction, improving the service life of the wire rope, and reducing the risk of operation.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 3 and Figure 7As shown in the embodiment of this utility model, a formwork lifting device for a beam yard includes a crossbeam 7; a lifting ring 8 is fixedly connected to the top of the crossbeam 7; L-shaped side beams 9 are fixedly connected to both ends of the crossbeam 7; characterized in that: a second bracket 15 is fixedly connected to the side wall of the lifting ring 8; a bolt 13 is installed on the top of the second bracket 15; a nut 14 is installed at the end of the bolt 13; a first bracket 12 is hinged to the bolt 13; a second limiting ring 11 is fixedly connected to the side wall of the first bracket 12; a first spring 16 is fixedly connected to the inner side wall of the second limiting ring 11; the first spring 16 is circumferentially distributed on the inner side wall of the second limiting ring 11; a first limiting ring 1 is fixedly connected to the end of the first spring 16; the first limiting ring 1 and the second limiting ring 1... The rings 11 are arranged in multiple sets on the first support 12. During operation, the wire rope is first passed through the first limiting ring 1 and tied to the hook. The hook is then hooked onto the lifting ring 8. The lifting device is then lifted. During the lifting process, the wire rope will swing when it tightens. At this time, the wire rope will collide and rub against the inner wall of the first limiting ring 1. The collision force of the first limiting ring 1 is then transmitted to the first spring 16. The first spring 16 is circumferentially distributed around the first limiting ring 1. In this way, the first spring 16 will absorb most of the force generated by the collision of the wire rope. The arrangement of the first limiting ring 1 and the first spring 16 effectively limits the swing of the wire rope during the lifting process due to tightening, thus improving the safety of the working process.

[0027] like Figure 6 As shown, a ball bearing 2 is embedded in the inner wall of the first limiting ring 1; the ball bearing 2 is distributed in multiple groups around the inner wall of the first limiting ring 1; during operation, when the wire rope is tightened and swings, the surface of the wire rope will rub against the inner wall of the first limiting ring 1. By adding ball bearing 2 inside the first limiting ring 1, the wire rope can contact the ball bearing 2 when swinging inside the first limiting ring 1, thereby converting sliding friction into rolling friction, greatly reducing friction, improving the service life of the wire rope, and reducing the risk of operation.

[0028] like Figure 2As shown, a second fixing block 33 is fixedly connected to the side wall of the crossbeam 7; a second spring 3 is fixedly connected to the top of the second fixing block 33; a third fixing block 34 is fixedly connected to the end of the second spring 3; the third fixing block 34 is fixedly connected to the side wall of the first bracket 12; a first fixing block 32 is fixedly connected to the side wall of the crossbeam 7; a third spring 31 is fixedly connected to the top of the first fixing block 32; the end of the third spring 31 is fixedly connected to the second limiting ring 11; during operation, the bolt 13 and nut 14 at the top of the second bracket 15 are hinged. The first support 12 is connected to the wire rope. When the wire rope swings, it will cause the first support 12 to move left and right. At this time, the second spring 3 and the third spring 31 will generate tension from the left and right directions, limiting the swing amplitude of the first support 12. The hinged design prevents the first support 12 from being damaged under the huge tension of the wire rope and provides a certain amount of room for movement. The second spring 3 and the first support 12 limit the room for movement of the first support 12, further limiting the swing of the wire rope and making the entire lifting process more stable.

[0029] like Figure 2 As shown, a permanent magnet alloy 4 is inserted at the bend of the L-shaped side beam 9; a handle 41 is fixed to the end of the permanent magnet alloy 4; during operation, the handle 41 is pinched and aligned with the square hole at the bend of the L-shaped side beam 9, and the attraction generated by the permanent magnet alloy 4 will firmly adhere to the square hole, blocking it. By setting the permanent magnet alloy 4, the square hole can be sealed, effectively preventing debris from entering. It can be taken out when the square hole is needed for lifting. The structure is simple and the operation is convenient.

[0030] like Figure 4 As shown, a sealing ring 5 is fixed to the end of the permanent magnet alloy 4; the sealing ring 5 is arranged around the four sides of the permanent magnet alloy 4; during operation, the attraction force generated by the permanent magnet alloy 4 on the L-shaped side beam 9 will squeeze the sealing ring 5. The sealing ring 5 will be deformed under a certain compressive force, and the deformation of the sealing ring 5 will fill the gap between the permanent magnet alloy 4 and the L-shaped side beam 9. By setting the sealing ring 5, liquid can be effectively prevented from flowing into the square hole and corroding the inside of the square hole, thus extending the service life of the lifting device.

[0031] like Figure 5 As shown, a fixing plate 61 is fixedly connected to the side wall of the permanent magnet alloy 4; a spring plate 6 is fixedly connected to the top of the fixing plate 61; the spring plates 6 are symmetrically arranged at the top and bottom of the fixing plate 61; during operation, when the handle 41 pushes the permanent magnet alloy 4 into the square hole, the spring plate 6 will be squeezed by the inner side wall of the square hole, and the squeezing force is transmitted to the fixing plate 61. The mutual squeezing of the spring plate 6, the fixing plate 61 and the inner side wall of the square hole causes deformation and gets stuck in the square hole. Through the setting of the spring plate 6, the permanent magnet alloy 4 can be more firmly and stably fixed on the square hole and is not easy to fall off.

[0032] Working principle: First, the wire rope is passed through the first limiting ring 1 and tied to the hook, which is then hooked onto the lifting ring 8. The lifting device is then lifted. During lifting, the wire rope oscillates as it tightens, causing it to collide and rub against the inner wall of the first limiting ring 1. This collision force is then transferred to the first spring 16, which is circumferentially distributed around the first limiting ring 1. Thus, the first spring 16 absorbs most of the force generated by the wire rope collision. When the wire rope oscillates as it tightens, its surface rubs against the inner wall of the first limiting ring 1. Due to the screw at the top of the second support 15... Bolt 13 and nut 14 are hinged to the first bracket 12, so when the wire rope swings, it will cause the first bracket 12 to move left and right. At this time, spring 3 and spring 31 will generate tension from the left and right directions, limiting the swing amplitude of the first bracket 12. Squeeze handle 41 and align it with the square hole at the bend of L-shaped side beam 9. The attraction generated by permanent magnet alloy 4 will firmly adhere to the square hole and block it. The attraction generated by permanent magnet alloy 4 on L-shaped side beam 9 will squeeze sealing ring 5. Sealing ring 5 will be deformed under a certain pressure. The deformation of sealing ring 5 will fill the gap between permanent magnet alloy 4 and L-shaped side beam 9.
