Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hoisting equipment, in particular to a hoisting equipment for finished concrete slab products. Background Art
[0002] Reinforced concrete slabs are slabs made of reinforced concrete materials. They are the basic structures or components in housing construction and various engineering structures. They are often used as roofs, floors, platforms, walls, retaining walls, foundations, floors, pavements, pools, etc., and have a wide range of applications. Reinforced concrete slabs are divided into square slabs, round slabs and special-shaped slabs according to their plane shapes. According to the force acting on the structure, they are divided into one-way slabs and two-way slabs. The most common ones are one-way slabs, four-sided supported two-way slabs and beamless slabs supported by columns. The thickness of the slab should meet the requirements of strength and stiffness. After the concrete slabs are produced, they need to be moved to the storage location and stacked using a mobile crane. However, during the movement, the concrete slabs are prone to large-scale shaking, and large-scale shaking concrete slabs may injure workers.
[0003] The patent document with the authorization announcement number CN220502461U3 discloses a finished concrete slab lifting equipment, which relates to the field of lifting equipment. It includes a lifting machine body, a lifting machine steel cable is provided on the lifting machine body, a lifting hook is fixedly installed at the end of the lifting machine steel cable, and clamping mechanisms are installed on both sides of the lifting machine body. The clamping mechanism includes a positioning sleeve, a clamping frame, a docking notch, a connecting plate and a docking screw. The positioning sleeve is movably installed on the steel beam on the lifting machine body, and the positioning sleeve is fixedly installed with a clamping frame. The lower end of the clamping frame is connected to a connecting plate, and docking notches are opened at the edges of both ends of the connecting plate. The connecting plates are provided with docking screws at both ends.

DETAILED DESCRIPTION
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0022] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0023] The utility model provides a finished concrete slab hoisting device, such as Figure 1-4 As shown, the finished concrete slab lifting equipment includes: a support frame 1; a cylinder 2 fixed on the support frame 1; a fixed block 3 rotatably installed at the bottom of the support frame 1; a moving wheel 4 arranged on the fixed block 3 for assisting in transferring the finished concrete slab; a fixed plate 5 installed on the support frame 1, on which a limit rod 19 for stabilizing the up and down movement of the finished concrete slab is installed; an adjustment plate 6 sleeved outside the limit rod 19; a clamping plate 7 arranged at the bottom of the adjustment plate 6 for stabilizing the concrete slab body; and an adjustment component arranged on the support frame 1 for adjusting the height of the concrete slab body.
[0024] It should be noted that the existing lifting equipment utilizes the force of the spring to stabilize the concrete slab when in use. Excessive compression of the spring can easily cause damage to the spring, while not tightening the spring will affect the limiting effect. At the same time, when the concrete slab is directly lifted by the lifting mechanism, the heavy concrete slab will generate a downward force, and the lifting mechanism is prone to reverse without limit, causing the concrete slab to fall, thereby affecting the lifting stability and resulting in low safety of the device.
[0025] In this device, when the finished concrete slab needs to be hoisted, the cylinder 2 is turned on to adjust the length of the support frame 1. When the support frame 1 is moved, the support frame 1 is sleeved outside the finished concrete slab, and then the output rod of the cylinder 2 is retracted, so that the clamping plate 7 can clamp the finished concrete slab. At this time, the concrete slab body can be hoisted using the adjusting assembly, and the difficulty of moving the device can be reduced by using the moving wheel 4.
[0026] In a further preferred embodiment of the utility model, the adjustment component includes a mounting frame 11 installed on the support frame 1, and a winding shaft 12 is rotatably installed on the mounting frame 11; a motor 13 fixed on the mounting frame 11, and the motor 13 is fixedly connected to the winding shaft 12; a pulley group 8 installed on the support frame 1, and a steel cable 9 connected to the adjustment plate 6 is wound around the pulley group 8, and the steel cable 9 is connected to the winding shaft 12.
[0027] In this embodiment, when the finished concrete slab needs to be hoisted, the motor 13 is turned on. The motor 13 drives the winding shaft 12 to rotate to wind up the steel cable 9, thereby lifting the adjustment plate 6. The pulley group 8 can effectively reduce the force required to lift the finished concrete slab, thereby reducing the difficulty of hoisting.
[0028] In a further preferred embodiment of the utility model, a hanging ring is installed on the top of the adjustment plate 6, a hook 10 is hung on the hanging ring, and the hook 10 is fixedly connected to the bottom of the pulley block 8.
[0029] In this embodiment, the adjusting plate 6 can be connected to the steel cable 9 by the hook 10 in cooperation with the hanging ring, and the adjusting plate 6 and the steel cable 9 can be easily separated.
[0030] In a further preferred embodiment of the utility model, a hydraulic rod 14 is installed on the mounting frame 11 , a resistance plate 15 is fixedly installed on the output rod of the hydraulic rod 14 , and a non-slip pad that can contact the winding shaft 12 is installed on the top of the resistance plate 15 .
[0031] In this embodiment, after the steel cable 9 is wound up, the hydraulic rod 14 is turned on, and the output rod of the hydraulic rod 14 is extended to make the resistance plate 15 resist against the winding shaft 12, thereby preventing the steel cable 9 from being continuously stressed and causing the winding shaft 12 to reverse, thereby increasing the safety of the device when in use.
[0032] In a further preferred embodiment of the utility model, two limit rings 16 are installed at the bottom of the adjustment plate 6, and baffles 17 are movably installed in the two limit rings 16. Limit plates 18 are installed on both sides of the two baffles 17. The two limit rings 16 are respectively located on both sides of the clamping plate 7.
[0033] In this embodiment, the baffle 17 can be limited by the limiting ring 16, and the limiting plate 18 can prevent the baffle 17 from easily falling off the limiting ring 16. The baffle 17 can limit the finished concrete slab to prevent the finished concrete slab from falling off.
[0034] In a further preferred embodiment of the utility model, a plurality of connecting ropes are installed on the top of the adjusting plate 6, the tops of the plurality of connecting ropes are fixedly connected to the hanging ring, and a rubber pad is installed on the bottom inner wall of the clamping plate 7.
[0035] In this embodiment, the force connecting the hanging ring and the adjusting plate 6 can be dispersed by the connecting rope, thereby stabilizing the angle of the adjusting plate 6, and the friction between the finished concrete slab and the clamping plate 7 can be increased by the rubber pad, thereby increasing the stability of the finished concrete slab.
[0036] In a further preferred embodiment of the utility model, the number of the adjustment plates 6, the adjustment components and the clamping plates 7 is not less than two, and the outer surfaces of the plurality of moving wheels 4 are all fixedly sleeved with anti-slip sleeves.
[0037] In this embodiment, the two adjustment plates 6, the two adjustment components and the two clamping plates 7 cooperate to synchronously limit the two sides of the finished concrete slab to ensure the stability of the finished concrete slab. The anti-slip sleeve can increase the friction between the moving wheel 4 and the ground to prevent the moving wheel 4 from slipping.
[0038] In a further preferred embodiment of the utility model, both adjustment plates 6 are provided with bayonet holes, and the plurality of bayonet holes are respectively sleeved outside the plurality of limit rods 19 , and the plurality of bayonet holes are inlaid with balls, and the plurality of balls are respectively in contact with the plurality of limit rods 19 .
[0039] In this embodiment, the ball bearings can ensure that the adjustment plate 6 moves up and down while ensuring the smoothness of the movement of the adjustment plate 6.
[0040] In summary, the device is highly flexible and can adjust its length according to the finished length of the concrete slab. It has high stability and can effectively prevent large shaking when hoisting the concrete slab body. It is easy to use and highly safe, and does not require staff to manually adjust the limit.
[0041] Compared with the related art, the device can adjust the length of the support frame 1 by setting the cylinder 2, so that the device is suitable for finished concrete slabs of different lengths. The finished concrete slab can be limited in multiple directions by setting the clamping plate 7 and the baffle 17. The limiting rod 19 can prevent the concrete slab from shaking easily when hoisting and transferring the finished concrete slab.
