Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of civil construction, in particular to a civil construction engineering material lifting device with high safety. Background Art
[0002] Material hoists are widely used equipment in industrial production, logistics and transportation, and construction. Their main function is to lift materials from the ground to a higher working position for further processing or storage. Material hoists play an important role in modern production and transportation processes. Their stability and safety directly affect production efficiency and operational safety.
[0003] Traditional material elevators generally include a base plate, a lifting device (such as an electric motor and chains, belts, etc.) and a control system; the material is placed directly on the base plate of the elevator during the lifting process. The base plate is responsible for carrying the material and lifting it to the required height during the operation of the elevator. The base plate of the elevator is usually designed to be a flat surface to support the stable placement of the material; however, existing material elevators usually do not have a special fixed structure to ensure that the material remains stable during the lifting process. The material is simply placed directly on the base plate and lacks sufficient fixing means; and in the material lifting process, especially when the elevator rises at a higher speed, the material on the base plate may be affected by vibration and inertia, causing the material to shake or deflect, which is easy to deflect or shake, and easily cause the material to fall, thereby causing a safety accident.
[0004] Therefore, a high-safety civil construction material lifting device is proposed to solve the problems existing in the prior art. Utility Model Content
[0005] The purpose of this utility model is to provide a highly safe civil construction material lifting device in response to the above-mentioned problems. The utility model forms a groove consistent with the shape of the heavy object when the heavy object is placed on the bottom plate through the cooperation of the contact rod and the buffer spring, and then fixes it through the extrusion plate to ensure that the contact rod fixes the heavy object, significantly reducing the lateral deviation or shaking of the heavy object during the lifting or moving process, providing higher stability and protection, and reducing potential safety hazards during the construction process. In order to achieve the above-mentioned utility model purpose, the technical solution adopted by the utility model is as follows:
[0006] According to one aspect of the utility model, a highly safe civil engineering material lifting device is provided, comprising a base plate, a plurality of lifting rods evenly arranged on the base plate, and a support frame provided on the base plate, a bottom plate provided in the support frame, a plurality of buffer springs provided on the base plate, and each buffer spring provided with a contact rod, and each contact rod provided with a contact head on the top, support plates provided on the left and right sides of the base plate, each support plate provided with a support seat, and each support seat provided with a hydraulic telescopic cylinder, and each hydraulic telescopic cylinder provided with an extrusion plate on the output end.
[0007] Preferably, the bottom plate and the support frame are of split design, and the bottom plate is composed of a plurality of square plates, each of the square plates is provided with a placement groove, and each placement groove is provided with a plurality of buffer springs.
[0008] Preferably, each of the square plates is provided with a plurality of card slots, and each of the square plates is provided with a card block that cooperates with the card slots.
[0009] Preferably, each of the card blocks is a wedge-shaped block, and the shape of each card slot is the same as that of the corresponding card block.
[0010] Preferably, each of the extrusion plates has an arc-shaped surface on one side close to the support frame.
[0011] Preferably, each of the contact heads is hemispherical.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0013] 1. The utility model is a high-safety civil engineering material lifting device. Through the cooperation of the contact rod and the buffer spring, when the heavy object is placed on the base plate, a groove consistent with the shape of the heavy object is formed, and then fixed by the extrusion plate to ensure that the contact rod fixes the heavy object, which significantly reduces the lateral deviation or shaking of the heavy object during lifting or moving, provides higher stability and protection, and reduces the potential safety hazards that may occur during the construction process.
[0014] 2. The utility model is a high-safety civil engineering material lifting device. By setting the card block as a wedge-shaped block and matching the card slot shape therewith, the wedge-shaped design enables the card block to be tightly fixed in the card slot, preventing the square plate from being displaced or loosened during use. At the same time, when a heavy object is placed on the base plate, the pressure exerted by the heavy object is transmitted to the card block, making the connection between the card block and the card slot tighter. The stable connection improves the overall structural stability of the base plate, reduces potential problems caused by gaps or looseness of the square plate, and ensures the reliability and service life of the base plate.

[0018] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in this specification are merely provided to help the reader gain a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.
[0019] See also Figures 1 to 2 The utility model provides a high-safety civil engineering material lifting device, and the technical solution is as follows:
[0020] It includes a base plate 1, on which a plurality of lifting rods 2 are evenly arranged, and a support frame 3 is provided on the base plate 1, a bottom plate is provided inside the support frame 3, a plurality of buffer springs 4 are provided on the bottom plate, and each buffer spring 4 is provided with a contact rod 5, and each contact rod 5 is provided with a contact head 6 on the top, support plates 7 are provided on the left and right sides of the base plate 1, each support plate 7 is provided with a support seat 8, and each support seat 8 is provided with a hydraulic telescopic cylinder 9, and each hydraulic telescopic cylinder 9 is provided with an extrusion plate 10 on the output end.
[0021] During lifting, the required lifting weight is placed in the support frame 3, and the weight contacts multiple contact heads 6 and contact rods 5, compressing several buffer springs 4. The support frame 3 is depressed to form a groove that is consistent with the shape of the weight. This groove can accurately match the outline of the weight, thereby increasing the contact area, ensuring that the weight is more evenly stressed, and reducing stability problems caused by uneven pressure; then the hydraulic telescopic cylinders 9 on both sides of the base plate are started, driving the extrusion plates 10 on both sides to move toward the center, squeezing and fixing multiple contact rods 5, and fixing the grooves to be formed. The extrusion plates 10 ensure that the contact rods 5 fix the weight by applying uniform pressure, and the contact rods 5 can tightly surround the weight, significantly reducing the lateral displacement or shaking of the weight during lifting or moving; when lifting materials, it provides higher stability and protection, reducing potential safety hazards that may occur during construction.
[0022] The base plate and the support frame 3 are of split design, and the base plate is composed of multiple square plates 11, each of the square plates 11 is provided with a placement groove 12, and each placement groove 12 is provided with multiple buffer springs 4; the split design allows the base plate to be decomposed into smaller square plates 11, which is convenient for transportation and handling, and can be assembled piece by piece during installation to adapt to different site conditions; individual square plates 11 can be adjusted or replaced as needed without replacing the entire base plate. This flexibility helps to deal with wear, damage or design changes, reducing maintenance costs and downtime.
[0023] Each of the square plates 11 is provided with a plurality of slots 13 , and each of the square plates 11 is provided with a block 14 that cooperates with the slots 13 . Each of the blocks 14 is a wedge-shaped block, and the shape of each slot 13 is the same as that of the corresponding block 14 .
[0024] The blocks 14 and the slots 13 of two adjacent blocks cooperate with each other, so that the two adjacent blocks serve as mutual support points, so that the base plate composed of multiple square plates 11 has higher stability during use; the wedge-shaped design enables the blocks 14 to be tightly fixed in the slots 13, preventing the square plates 11 from being displaced or loosened during use. At the same time, when a heavy object is placed on the base plate, the pressure exerted by the heavy object is transmitted to the blocks 14, making the connection between the blocks 14 and the slots 13 tighter. The stable connection improves the overall structural stability of the base plate, reduces potential problems caused by gaps or looseness of the square plates 11, and ensures the reliability and service life of the base plate.
[0025] Each of the extrusion plates 10 has an arc-shaped surface on one side close to the support frame 3; the arc-shaped surface can reduce the contact area with the contact rod 5, thereby reducing friction and wear. Reducing friction can reduce damage to the contact rod 5 during the extrusion process and improve the overall efficiency and life of the system; the arc-shaped surface can more evenly fix the contact rod 5 in the predetermined position, ensure the stability and accuracy of the contact rod 5, and help maintain the overall accuracy of the system.
[0026] Each of the contact heads 6 is hemispherical; the hemispherical contact heads 6 can better adapt to the curved surface and irregular shape of the bottom surface of the object and provide stable support, which makes the object more stable on the base plate and avoids the object from tilting or sliding; the hemispherical contact heads 6 can evenly distribute the pressure of the heavy object to multiple contact points instead of concentrating it on a certain point, which helps to reduce the local pressure on the base plate and the spring, thereby reducing the risk of local wear and damage.
[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
