Flooring press

Abstract

This utility model discloses a flooring installation clamping device, including a movable frame, an I-shaped fixing frame, a clamping mechanism, a clamping plate, and an auxiliary striking mechanism. Through the clamping mechanism and the auxiliary striking mechanism, the sleeves connected to the four sets of electric hydraulic piston rods in the clamping mechanism can be lowered synchronously by extending and retracting. The connecting plate installed at the bottom of the sleeve drives the clamping plate to extend from the movable frame and move towards the surface of the installed floor. As the four sets of electric hydraulic piston rods continuously extend, the clamping plate and its bottom rubber plate adhere to and clamp the floor. Then, the piston end of the electric cylinder in the auxiliary striking mechanism drives the striking plate at the bottom of the mounting plate to strike the clamping plate. A second spring and a telescopic rod are installed between the mounting plate and the striking plate to provide a certain buffering force to the striking plate. The combination of the second spring and the telescopic rod absorbs impact energy, reducing the reaction force of the strike on the clamping plate and the floor, and extending the life of the components.

Description

Technical Field

[0001] This utility model relates to the field of flooring installation technology, specifically to a flooring installation clamping device. Background Technology

[0002] The installation of flooring is extremely important during the renovation process, as its flatness directly affects the overall decoration effect of the house. Ensuring tight joints and a smooth surface are the core requirements for construction quality during flooring installation.

[0003] A search revealed that the prior art, under publication number CN207660260U, discloses a floor laying and pressing device, comprising a platform, a first bearing plate, a connecting rod, and a pressure plate. A piling groove is formed in the middle of the platform, and the first bearing plate is fixedly connected to the inner wall of one end of the piling groove. Support plates are fixedly connected to the upper surfaces of both ends of the first bearing plate, and a horizontal plate is fixedly connected to the inner top of the two support plates. A connecting rod passes through the middle of the first bearing plate, and a pressure plate is fixedly connected to the bottom of the connecting rod, located below the first bearing plate. The beneficial effects are: by setting a pressure plate below the first support plate, the floor is compressed, facilitating flattening and improving pressing efficiency; by connecting the connecting rod and a return spring to the pressure plate, a small amount of compressive force is applied to the floor, facilitating control of the striking force; and by setting a limiting plate and a limiting groove on the second support plate and the pressure plate respectively, the pressing height of the floor is controlled, preventing excessive force from pressing the floor too deeply.

[0004] However, in existing technology, the limiting plate is pressed tightly against the floor, at which point the pressure plate is above the floor to be pressed. Then, the hammer head is pulled up and then lowered by the pull rope to strike the connecting rod. The connecting rod drives the pressure plate to squeeze the floor and press the pressure plate down. Workers need to repeatedly pull the rope to reset the hammer head, which is inefficient. Especially when laying large areas, it is easy to cause operator fatigue. Moreover, the falling speed of the hammer head is affected by the length of the pull rope and the release force, resulting in large differences in the striking force each time. It is easy to damage the floor due to overpressure (such as cracking of solid wood flooring) or cause loose splicing due to underpressure. Therefore, a pressing device for floor laying is proposed. Utility Model Content

By setting up a clamping mechanism and an auxiliary striking mechanism, the clamping mechanism can drive the clamping plate to clamp the floor, and the auxiliary striking mechanism can strike the clamping plate, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0017] This invention, through the setting of a pressing mechanism and an auxiliary striking mechanism, allows the sleeves connected to the four sets of pressing mechanisms to descend synchronously via the extension and retraction of the electric hydraulic piston rods. The connecting plate installed at the bottom of the sleeve drives the pressing plate to extend from the movable frame and move towards the laid floor surface. As the four sets of electric hydraulic piston rods continuously extend, the pressing plate and its bottom rubber plate adhere to and press against the floor. Then, the piston end of the electric cylinder in the auxiliary striking mechanism drives the striking plate at the bottom of the mounting plate to strike the pressing plate. The second spring and telescopic rod between the mounting plate and the striking plate cooperate to give the striking plate a certain buffering force.

[0023] 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.

[0024] Please see Figures 1-4This utility model provides a technical solution: a floor laying clamping device, including a movable frame 1, an I-shaped fixing frame 2, a clamping mechanism 3, a clamping plate 4, and an auxiliary striking mechanism 5; the movable frame 1 is fixedly installed on the inner wall of the movable frame 1, and four sets of clamping mechanisms 3 are symmetrically fixedly installed on the surfaces at both ends of the I-shaped fixing frame 2. The telescopic ends of the four sets of clamping mechanisms 3 are equipped with clamping plates 4 for clamping the laid floor, and an auxiliary striking mechanism 5 for striking the clamping plate 4 is installed in the middle of the I-shaped fixing frame 2.

[0025] The mobile frame 1 is made of lightweight metal material (such as aluminum alloy) and welded together. The bottom is equipped with a combination of casters and directional wheels. The I-shaped fixing frame 2 is rigidly connected to the inner wall of the mobile frame 1 through high-precision welding. The four sets of clamping mechanisms 3 are symmetrically arranged to form a torque couple, avoiding equipment displacement caused by unilateral pressure.

[0026] The clamping mechanism 3 includes an electric hydraulic rod 31, which is fixedly installed on the top of the I-shaped fixing frame 2. One end of the piston rod of the electric hydraulic rod 31 passes through the I-shaped fixing frame 2 and is fixedly installed with a sleeve 32. A sliding plate 34 is slidably installed inside the sleeve 32. A lifting rod 35 is fixedly installed at the bottom of the sliding plate 34. A connecting plate 36 is fixedly installed at the bottom of the lifting rod 35. The bottom of the connecting plate 36 is fixedly connected to the top of the clamping plate 4.

[0027] The electro-hydraulic rod 31 uses a servo closed-loop control model with a built-in pressure sensor that provides real-time pressure feedback. The sleeve 32 is made of chrome-plated steel cylinder fitted with a polytetrafluoroethylene guide sleeve, and the sliding plate 34 is coated with a wear-resistant coating.

[0028] It is worth noting that the electric hydraulic rods 31 in the four sets of clamping mechanisms 3 are set synchronously.

[0029] A first spring 33 is fixedly installed on the inner top of the sleeve 32, and the bottom of the first spring 33 is fixedly connected to the top of the sliding plate 34.

[0030] The first spring 33 adopts a variable diameter helical spring design with segmented changes in stiffness coefficient. The composite guide structure ensures that the lifting rod 35 moves vertically with an angle deviation of <0.5°.

[0031] The auxiliary striking mechanism 5 includes an electric cylinder 51, which is fixedly installed at the top center of the I-shaped fixing frame 2. One end of the piston of the electric cylinder 51 passes through the I-shaped fixing frame 2 and is fixedly connected to a mounting plate 52. Three sets of second springs 53 are symmetrically fixedly installed at the bottom of the mounting plate 52, and striking plates 54 are fixedly connected to the bottom of the three sets of second springs 53.

[0032] The mounting plate 52 is located inside the second spring 53 and has a telescopic rod 55 fixedly installed. The bottom of the telescopic rod 55 is fixedly connected to the top of the striking plate 54, and a rubber plate is fixedly glued to the bottom of the striking plate 54.

[0033] The second spring 53 adopts a parallel arrangement of spring groups, the telescopic rod 55 has a built-in hydraulic damper, the rubber plate is made of nitrile rubber with a hardness of 70±5 Shore A, the three sets of spring-damping systems can absorb 90% of the reaction impact force, the impact frequency is adjustable in the range of 2-8Hz, adapting to the construction needs of different floor materials, the rubber buffer layer reduces the impact pressure to below 0.3MPa, avoiding surface damage.

[0034] Ventilation openings are provided on both sides of the movable frame 1, and a push rod is installed on one side of the movable frame 1 to facilitate pushing by workers.

[0035] Ventilation gaps ensure heat dissipation for internal electric components.

[0036] The side wall of the clamping plate 4 is slidably connected to the inner wall of the movable frame 1, and a rubber plate 6 to prevent the floor from being scratched is fixedly bonded to the bottom of the clamping plate 4.

[0037] Rubber sheet 6 is made of 3mm thick EPDM material with diamond-shaped anti-slip texture. EPDM rubber sheet has both cushioning and anti-slip functions, with a friction coefficient of 1.2.

[0038] Four sets of reinforcing frames 7 are symmetrically fixed at the bottom of both ends of the I-shaped fixing frame 2. One side of each set of reinforcing frames 7 is fixedly installed to the inner wall of the movable frame 1.

[0039] The reinforcing frame 7 adopts a triangular truss structure and is made of 16Mn low alloy steel. It is fixed with shear-resistant high-strength bolts at the connection with the movable frame. The truss structure increases the overall bending stiffness by 60%, and the bolt connection method facilitates later maintenance and replacement. The four sets of reinforcing frames form a spatial stability system, and the equipment's torsional resistance reaches 1500 N·m.

[0040] When workers use the equipment, the operator pushes the movable frame 1 to the construction area using a push rod. The combination of omnidirectional and directional wheels ensures flexible steering and precise positioning. Ventilation gaps ensure heat dissipation for the internal electric components. The four sets of electric hydraulic rods 31 start synchronously, and the piston rods push the sleeve 32 downward. The first spring 33 is compressed, generating a buffering force. Through the connecting plate 36 installed at the bottom of the sleeve 32, the pressing plate 4 extends from the movable frame 1 and moves towards the laid floor surface. As the piston rods of the four sets of electric hydraulic rods 31 continue to extend, the pressing plate 4 and its bottom rubber plate 6 adhere to and press against the floor. The clamping mechanism 3 applies continuous pressure to the floor surface with the clamping plate 4 in a flexible contact manner, eliminating the gap between the floor and the subfloor. The electric cylinder 51 drives the mounting plate 52 to press down, and the three sets of second springs 53 compress and store energy, driving the striking plate 54 to perform pulse-like tapping on the top of the clamping plate 4 at a frequency of 2-8Hz. The rubber plate buffers the impact force, and the telescopic rod 55 limits the amplitude (≤3mm), ensuring that the impact energy is effectively transferred to the floor joints. The continuous static pressure of the clamping mechanism 3 and the dynamic impact of the auxiliary tapping form a compound force, which promotes the uniform diffusion of the floor adhesive and eliminates the micro-deformation stress of the floor.

[0041] The control method of the electro-hydraulic rod and the electric cylinder in this application is to automatically control them through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming, which is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape and their combination, so the control method and circuit connection will not be explained in detail in this application.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
