A concrete precast component hoisting and demolding device

Abstract

This utility model discloses a concrete precast component hoisting and demolding device, belonging to the field of concrete precast component processing technology. It aims to solve the problem that existing technologies generally lack effective adjustment structures for hoisting equipment, resulting in fixed hoisting spacing. When hoisting wider precast components, this fixed spacing cannot fully cover the effective stress area of ​​the precast component, causing uneven stress at both ends during hoisting and easily leading to bending deformation in the central area. Conversely, when hoisting narrower precast components, the fixed hoisting spacing is too large, causing a mismatch between the precast component's center of gravity and the hoisting center, resulting in violent shaking during hoisting. This not only poses a safety hazard of colliding with surrounding equipment or molds but also causes additional stress due to the shaking, leading to chipping at the edges and corners, surface damage, and other defects. The device includes a hoisting frame.

Description

Technical Field

[0001] This utility model belongs to the field of concrete precast component processing technology, specifically relating to a concrete precast component hoisting and demolding device. Background Technology

[0002] With economic development, the construction industry is developing faster and faster. Precast concrete components are often used in the construction process. Precast concrete components are made by placing concrete raw materials into molds, drying and solidifying them, demolding them, and finally using the precast concrete components.

[0003] Currently, precast concrete lifting and demolding devices generally lack effective adjustment structures for the lifting equipment, resulting in a fixed lifting spacing. When lifting wider precast components, this fixed spacing cannot fully cover the effective stress area of ​​the precast component, causing uneven stress on both ends during lifting and easily leading to bending deformation in the central area. Conversely, when lifting narrower precast components, the fixed lifting spacing is too large, causing a mismatch between the center of gravity and the lifting center. This results in violent shaking of the precast component during lifting, posing a safety hazard of colliding with surrounding equipment or molds. Furthermore, the additional stress generated by the shaking can cause chipping at the edges and corners, surface damage, and other defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a concrete precast component hoisting and demolding device. This device aims to solve the problem that existing technologies generally lack an effective adjustment structure for the hoisting equipment, resulting in a fixed hoisting spacing. When hoisting wider precast components, this fixed spacing cannot fully cover the effective stress area of ​​the precast component, causing uneven stress at both ends during hoisting and easily leading to bending deformation in the central area. Conversely, when hoisting narrower precast components, the fixed hoisting spacing is too large, causing a mismatch between the precast component's center of gravity and the hoisting center. This results in violent shaking of the precast component during hoisting, posing a safety hazard of colliding with surrounding equipment or molds. Furthermore, the additional stress generated by the shaking can cause chipping at the edges and corners, surface damage, and other adverse phenomena.

[0009] Furthermore, the first driven support frame is fixedly mounted on the upper section of the middle part of the hoisting frame, and all three first driven support frames form a driven support connection with the positive and negative lead screws.

[0010] Furthermore, the support guide frame utilizes anti-fall guide blocks and guide grooves to form a horizontal guide connection with the hoisting frame.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] When hoisting precast concrete components in molds of different widths, the operator can start the first motor to drive the positive and negative lead screws to rotate. At this time, the two lead screw sleeves that cooperate with the positive and negative lead screws will drive their respective fixed support guides and the assembly frame below them to move relative to each other under the support and guidance of the anti-fall guide block and the guide groove. Since the assembly frame is equipped with hoisting components, the distance between the two hoisting components can be adjusted through the above operation. After the distance adjustment is completed, the operator can start the second motor to make the rotating rod in the assembly frame rotate. At this time, the steel wire rope wound around the rotating rod will be loosened, thereby driving the hoisting device fixed at the end to be lowered, and finally realizing the hoisting and demolding operation of the precast concrete component.

[0017] After the lifting device is lowered to the lifting position of the precast concrete component and fixed, the operator can activate the cylinder to move the fixed plate downwards. At this time, the pressure plates installed on both sides below the fixed plate will press against the top of both sides of the mold. In this state, the downward pressure of the pressure plate on the mold and the lifting force of the lifting component on the precast component form a pulling force in different directions. Through the cooperation of this two-way force, the bonding resistance between the precast component and the mold can be effectively reduced, which facilitates the demolding operation. When there is a difference in the thickness of the mold, the operator can adjust the position of the pressure plate in real time according to the screw groove, the preset slot, and the bolt rod.

[0024] 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.

[0025] This specific embodiment is a concrete precast component hoisting and demolding device, the structural schematic diagram of which is shown below. Figures 1 to 4As shown, the system includes a lifting frame 1, with an adapter lifting mechanism 2 installed in the middle of the lifting frame 1. The adapter lifting mechanism 2 includes an adjustment assembly 21 and its components, two support guides 215 and three first driven support frames 213. An auxiliary demolding mechanism 3 is installed in the middle of the first driven support frame 213 below it. The adjustment assembly 21 is mounted in the middle of the lifting frame 1 and includes a first motor 211, which is fixedly installed on the upper side of the lifting frame 1. The output end of the first motor 211 is connected to a positive and negative lead screw 212, and the three periphery sections of the positive and negative lead screw 212 are equipped with first driven support frames 213. Support frames 213 are fixedly mounted on the upper section of the middle part of the hoisting frame 1, and the three first driven support frames 213 are all connected to the positive and negative lead screws 212. Lead screw sleeves 214 are screwed onto both sides of the middle part of the positive and negative lead screws 212, and support guide frames 215 are fixed around the periphery of the two lead screw sleeves 214. Anti-fall guide blocks 216 are fixed to the top of the two support guide frames 215. Guide grooves 217 are opened on both sides of the top of the middle part of the hoisting frame 1. The support guide frames 215 form a horizontal guiding connection with the hoisting frame 1 through the anti-fall guide blocks 216 and the guide grooves 217. Assembly frames 22 are fixed below the two support guide frames 215. The assembly 2 is equipped with a hoisting component 23, which includes a second motor 231. The second motor 231 is fixedly installed on the middle of one side of the assembly frame 22. The output end of the second motor 231 is connected to a rotating rod 232. The middle section of the rotating rod 232 is movably supported by a second driven support frame 233. A steel wire rope 234 is wound around the periphery of the rotating rod 232, and the end of the steel wire rope 234 is fixedly connected to a lifting device 235. When hoisting concrete precast components in molds of different widths, the operator can start the first motor 211 to drive the positive and negative lead screws 212 to rotate. At this time, the positive and negative lead screws 212 cooperate with the first motor 211 to drive the positive and negative lead screws 212 to rotate. The two lead screw sleeves 214 will drive the support guides 215 and the assembly frame 22 below them, which are fixed to each other, to move relative to each other under the support and guidance of the anti-fall guide block 216 and the guide groove 217. Since the assembly frame 22 is equipped with a hoisting component 23, the distance between the two hoisting components 23 can be adjusted through the above operation. After the distance adjustment is completed, the operator can start the second motor 231 to make the rotating rod 232 inside the assembly frame 22 rotate. At this time, the steel wire rope 234 wound around the rotating rod 232 will be relaxed, thereby driving the hoisting device 235 fixed at the end to be lowered, and finally realizing the hoisting and demolding operation of the precast concrete component.

[0026] The auxiliary demolding mechanism 3 includes a fixed bracket 31, which is fixed to the bottom end of the first driven support frame 213 in the middle. A cylinder 32 is installed in the middle of the fixed bracket 31, and a fixed plate 33 is connected to the extended end of the cylinder 32. Threaded grooves 34 are provided on both sides of the inner end of the fixed plate 33, and pressure plates 35 are provided on the inner side of the threaded grooves 34. Pre-set slots 36 are opened on both sides of the two pressure plates 35, and bolt rods 37 are inserted into the middle of the two pre-set slots 36. The pressure plates 35 are fixedly connected to the fixed plate 33 by bolt rods 37 and threaded grooves 34. When the lifting device 235 is lowered to contact the precast concrete component… After the hoisting part is fixed, the operator can start the cylinder 32, which will cause its extended end to move the fixed plate 33 downward. At this time, the pressure plates 35 installed on both sides below the fixed plate 33 will press on the top of both sides of the mold. In this state, the downward pressure of the pressure plate 35 on the mold and the hoisting force of the hoisting component 23 on the precast part form a pulling force in different directions. Through the cooperation of this two-way force, the bonding resistance between the precast part and the mold can be effectively reduced, which facilitates the demolding operation. When there is a difference in the thickness of the mold, the operator can adjust the position of the pressure plate 35 in real time according to the screw groove 34, the preset slot 36, and the bolt rod 37.

[0027] Working principle: When hoisting precast concrete components in molds of different widths, the operator can start the first motor 211 to drive the positive and negative lead screws 212 to rotate. At this time, the two lead screw sleeves 214 that cooperate with the positive and negative lead screws 212 will drive their respective fixed support guides 215 and the assembly frame 22 below them to move relative to each other under the support and guidance of the anti-fall guide block 216 and the guide groove 217. Since the assembly frame 22 is equipped with hoisting components 23, the distance between the two hoisting components 23 can be adjusted through the above operation. After the distance adjustment is completed, the operator can start the second motor 231 to make the rotating rod 232 in the assembly frame 22 rotate. At this time, the steel wire rope 234 wound around the rotating rod 232 will be unwound, thereby driving the hoisting device fixed at the end. 235 is lowered to finally realize the hoisting and demolding operation of the precast concrete component. After the hoisting device 235 is lowered to the hoisting part that contacts the precast concrete component and is fixed, the operator can activate the cylinder 32 to make its extended end drive the fixed plate 33 to move downward. At this time, the pressure plates 35 installed on both sides below the fixed plate 33 will press on the top of both sides of the mold. In this state, the downward pressure of the pressure plate 35 on the mold and the hoisting force of the hoisting component 23 on the precast component form a pulling force in different directions. Through the cooperation of this two-way force, the bonding resistance between the precast component and the mold can be effectively reduced, which facilitates the demolding operation. When there is a difference in the thickness of the mold, the operator can adjust the position of the pressure plate 35 in real time according to the screw groove 34, the preset slot 36, and the bolt rod 37.
