Description

Technical Field

[0001] The invention relates to the technical field of fireproof rock wool equipment, and in particular to a heat-insulating nail pre-installation device for fireproof rock wool. Background Art

[0002] In the construction field, rock wool is a commonly used material widely used for thermal insulation, sound insulation and fire protection. Traditionally, the installation process of rock wool board involves drilling insulation nails directly into the installation surface. Although this process is effective in achieving the purpose of fixing by penetrating the rock wool board into the wall or other structure, it has certain limitations in installation efficiency.

[0003] The process first requires accurate measurement of the installation surface and marking the specific installation position of the insulation nail. Then, use an electric drill to drill holes on the rock wool at the marked position, insert the insulation nails into the rock wool holes, and finally expand and fix the insulation nails by hammering or other means. In the process of drilling holes on the marked positions of the rock wool with an electric drill, the fibers are separated by mechanical force and released into the air, causing personnel to be affected by the fibers, resulting in low installation efficiency. For this reason, we propose a pre-installation device for insulation nails of fireproof rock wool. Summary of the invention

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Refer to the attached Figure 1-2A heat preservation nail pre-installation device for fireproof rock wool comprises a roller conveyor belt 1, a side plate 11, and a motor 12. The side plate 11 is installed between the legs of the roller conveyor belt 1. The roller conveyor belt 1, the side plate 11, and the legs of the roller conveyor belt 1 are respectively installed with a rotating wheel 2, a middle plate 3, a supporting rod 4, a top rod 5, a sliding block 6, and a fixed shaft 7 located inside the roller conveyor belt 1. The fixed shaft 7 is fixedly installed on the side plate 11, and the fixed shaft 7 is located at the position of the rotating wheel 2. The middle plate 3 is installed on both sides of the rotating wheel 2. A motor mounting seat for fixing the motor 12 is also installed on the side plate 11. The motor mounting seat can be a U-shaped structure for fixing the motor 12. The rotation of the motor 12 drives the rotating wheel 2 to rotate. A bracket 13 is also installed on the roller conveyor belt 1. A lifting groove 14 for accommodating the sliding of the lower pressing plate 16 is opened between the bracket 13 and the roller conveyor belt 1. The bracket 13 is also provided with an upper pressing plate 15, and the upper pressing plate 15 and the lower pressing plate 16 are relatively arranged to fix the fireproof rock wool. The two ends of the lifting groove 14 are arc structures, which are used to adapt to the roller curvature of the end of the lower pressing plate 16, so as to limit the lower pressing plate 16 and prevent the lower pressing plate 16 from being damaged by excessive lifting, and the upper pressing plate 15 and the lower pressing plate 16 are both rollers and sleeve rollers. The sleeve roller surface is formed along the axial direction, and the sections of the upper pressing plate 15 and the lower pressing plate 16 correspond to each other, which is convenient for clamping the fireproof rock wool. The section of the lower pressing plate 16 is equidistantly provided with needles for piercing the fireproof rock wool, and the section of the upper pressing plate 15 is provided with a groove for accommodating the needles. The curved surface structure is relatively clamped, which is easy to cause the surface of the fireproof rock wool to sink, which will cause the occurrence of thermal bridge effect, forming a channel for heat and flame propagation, and weakening the fire protection effect.

[0036] Refer to the attached Figure 3 The runner 2 is an irregular curved surface structure, which includes a concave surface of the side of the runner 2 that is concave inward, a first protrusion 21 that is protruded outward, and a second protrusion 22 that is further protruded, which are connected in sequence.

[0037] Refer to the attached Figure 4The output end of the motor 12 is fixedly mounted on the rotating wheel 2 to drive it to rotate. The pushing device includes a middle plate 3, a middle plate rotating shaft 31, a hinge shaft 32, a limit shaft 33, and a roller shaft 34 arranged on one side of the rotating wheel 2. The middle plate 3 is a polygonal structure, and the middle plate rotating shaft 31, the hinge shaft 32, the limit shaft 33, and the roller shaft 34 are arranged at the corner of the middle plate 3. The two ends of the middle plate rotating shaft 31 are respectively hinged on the middle plate 3 and the legs of the roller conveyor 1, and the two ends of the hinge shaft 32 are hinged on the middle plate 3 and one end of the support rod 4. The other end of the support rod 4 A supporting seat 41 for supporting the roller shaft of the lower pressure plate 16 is also installed on it. The limiting shaft 33 is fixedly installed on the middle plate 3, and the limiting shaft 33 and the fixed shaft 7 are connected by the middle plate tension spring 36. A roller 35 is sleeved on the roller shaft 34 and abuts against the curved surface of the rotating wheel 2. The middle plate rotating shaft 31, the hinge shaft 32, and the limiting shaft 33 are located on the side away from the rotating wheel 2, and the roller shaft 34 is located on the other side of the rotating wheel 2. A sliding sleeve 42 is also sleeved on the support rod 4, and the sliding sleeve 42 is fixed on the side plate 11, so that the support rod 4 slides in the sliding sleeve 42. The state at this time is the initial state.

[0038] Reference Figure 5-6 The middle plate tension spring 36 pulls the limit shaft 33, so that the middle plate 3 approaches the rotating wheel 2, and the roller 35 is pressed against the side wall of the rotating wheel 2. The motor 12 drives the rotating wheel 2 to rotate until the first protrusion 21 presses against the roller 35 and reaches the first stroke. At this time, the middle plate 3 rotates around the middle plate rotating shaft 31, and the hinge shaft 32 pushes the hinged support rod 4 to slide along the direction of the sliding sleeve 42. The support seat 41 supports the roller shaft of the lower pressure plate 16 to move upward, and the needle on the lower pressure plate 16 penetrates into the rock wool to lift up the fireproof rock wool, ensuring To ensure that it will not loosen or sag, and to ensure the integrity and continuity of the fireproof rock wool, the limit shaft 33 pulls the middle plate tension spring 36 to store energy, the wheel 2 continues to rotate, and the roller 35 reaches the second protrusion 22, and the support rod 4 will further move upward. At this time, the support rod 4 lifts the lower pressure plate 16 to further lift the fireproof rock wool upward, and the upper pressure plate 15 and the lower pressure plate 16 clamp the fireproof rock wool to fix it. The design of the two-stage lifting mechanism makes the fixing process simpler and more efficient. The fixation can be completed by simply inserting the needle into the rock wool and clamping the rock wool.

[0039] Reference Figure 7 The other side of the rotating wheel 2 is also provided with a middle plate 3 which abuts against the rotating wheel 2. The hinge shaft 32 on the middle plate 3 is hinged with a gradient rod 54. The gradient rod 54 is a combination of a plane and a curved surface. A pulley 53 is provided on the plane of the gradient rod 54 to slide along the plane and the curved surface. A top rod 5 is installed on the pulley 53. Figure 7 The push rod 5 is in the initial state, and a sliding sleeve 42 is sleeved on the push rod 5 to limit it. When the wheel 2 rotates and passes through the first stroke, the pulley 53 is located on the half slope of the curved surface of the gradient rod 54. When the wheel 2 passes through the second stroke, the pulley 53 is located at the top of the curved surface of the gradient rod 54, so that the push rod 5 has a two-end lifting stroke.

[0040] Reference Figure 8-9 , in the attached Figure 8-9 The push rod 5 is in the process of the first stroke. The push rod slider 51 on the push rod 5 slides along the push rod slide groove 52 installed on the side plate 11. The push rod 5 is also provided with a slide groove 55 extending from the end of the push rod 5. The slide groove 55 is slidably provided with a slide block 6. The head of the slide block 6 is provided with a container for placing the heat preservation nails. The tail of the slide block 6 is provided with a slide block 61. The slide block 61 has a large bottom and a small top structure, and the bottom of the slide block 61 is The top of the top rod is a vertical surface. A vertical frame 521 is installed on both sides of the top rod slide 52. The vertical frames 521 are connected to the same connecting rod 522. A rotatable pressure rod 524 is sleeved on the connecting rod 522. A torsion spring 523 is sleeved on the connecting rod 522, and one end of the torsion spring 523 is fixed on the vertical frame 521, and the other end of the torsion spring 523 is fixed on the pressure rod 524, so that the pressure rod 524 is against the direction of the slider 6. The end face of the pressure rod 524 is a bevel. The pressure rod 524 is provided with a pressure rod protrusion 525 at a position close to the slider 6, and the pressure rod protrusion 525 is a beveled surface. The top rod 5 is also provided with a strip block 56, and a lifting block 57 is provided on the strip block 56. The lifting block 57 is a beveled surface. The slider 6 is provided with a guide rod 62, which runs through the lifting block 57. One end of the guide rod 62 is sleeved with a force storage spring 63 that is supported on the slider 6, and the other end of the guide rod 62 is sleeved with a bolt for adjusting By adjusting the distance between the slider 6 and the lifting block 57, the amount of energy stored in the force storage spring 63 can be changed. When the push rod 5 is lifted in one section, the beveled surface of the pressure rod 524 passes through the beveled surface at the bottom of the slider protrusion 61 to lift the pressure rod 524 along the surface of the slider protrusion 61. At this time, the slider protrusion 61 continues to move in the direction of the lifting block 57. At this time, the push rod 5 continues to be lifted, and the pressure rod protrusion 525 is against the slider protrusion 61. At this time, the force storage spring 63 begins to deform and store energy.

[0041] Reference Figure 10-11 , attached Fig.10 This is the state after the one-stage lifting of the push rod 5. During the two-stage lifting, the lifting block 57 pushes the pressure rod 524 to rotate in the direction of the connecting rod 522, that is, the pressure rod 524 is tilted. At this time, the abutment between the pressure rod protrusion 525 and the slider protrusion 61 is released, and the slider 6 is in the lifting state, completing the two-stage lifting. The container where the insulation nails are placed follows the slider 6 for a second lifting. In the first stage, the container where the insulation nails are placed is abutted against the bottom of the fireproof rock wool. If the insulation nails are not penetrated only once, a safety hazard caused by the scattering of the insulation nails may occur. In the second stage, the insulation nails are penetrated into the fireproof rock wool through the stroke of the slider 6.

[0042] Working principle: The driving motor 12 fixed on the side plate 11 drives the rotating wheel 2 to make eccentric movement. In the initial state, the roller on the middle plate 3 is against the concave surface of the rotating wheel 2. The middle plate rotating shaft 31 of the middle plate 3 is hinged on the leg of the roller conveyor 1. The middle plate tension spring 36 pulls the middle plate 3 to rotate between the limit shaft and the fixed shaft on the middle plate 3. When the rotating wheel 2 rotates, the rotating wheel 2 pushes the middle plate 3 to rotate around the middle plate rotating shaft 31. When the first protrusion 21 of the rotating wheel 2 rotates to the position close to the roller 35, the middle plate 3 is pulled to rotate. When the middle plate 3 is abutted, the middle plate 3 rotates to the first stroke state. At this time, the upper part 4 hinged on the middle plate 3 is displaced to lift the lower pressing plate 16. The needles on the lower pressing plate 16 penetrate into the fireproof rock wool to prevent the fireproof rock wool from slipping excessively in the roller conveyor 1. When the second protrusion 22 of the rotating wheel 2 abuts against the roller 35, the middle plate 3 rotates to the second stroke state. At this time, the lower pressing plate 16 is further lifted to ensure that the upper pressing plate 15 and the lower pressing plate 16 can firmly fix the fireproof rock wool, thereby creating a stable supporting surface;

[0043] The same structure of the push rod 5 realizes two-stage sliding of the slope rod 54 along the direction of the roller conveyor belt 1. In the initial state, the push rod is at the bottom of the slope rod 54. In the first stroke state, the push rod 5 is located on the slope of the slope rod 54. At this time, under the action of the storage spring 63, the push rod 5 and the slider 6 are pushed up together until the pressure rod protrusion 525 on the pressure rod 524 abuts against the slider protrusion 61 on the slider 6, and the storage spring 63 begins to be compressed, and the slider 6 abuts under the fireproof rock wool. When it reaches the second state, the push rod 5 continues to lift upward, and the force storage spring 63 is compressed and stored until the end of the pressure rod 524 abuts against the lifting block 57 to lift the pressure rod 524. At this time, the pressure rod protrusion 525 and the slider protrusion 61 are separated from the abutment, and the slider 6 is quickly lifted by the force storage spring 63 to insert the insulation nail into the fireproof rock wool in advance, improving work efficiency. The two-stage lifting can ensure that the slider is pre-positioned under the fireproof rock wool in the first stage. By performing rough positioning first, it is ensured that the insulation nail is correctly aligned with the fireproof rock wool, thereby avoiding deviation or damage to the surrounding materials. After the first lifting, the system has been stabilized and aligned with the target area. The second rapid lifting can reduce the movement or deformation of the material, thereby improving the accuracy of insertion and reducing the stress concentration on the fireproof rock wool. This protects the integrity of the material and reduces the risk of rupture or damage caused by rapid or single lifting. Under the premise of ensuring the insertion of the insulation nails, after the first step determines the correct position, the second step can be quickly executed, reducing the overall operation time. The step-by-step approach avoids mechanical failures or operational errors that may be caused by rapid and direct lifting, thereby improving the overall operation safety. Through two-stage jacking, it can also ensure that the insulation nails are effectively and safely inserted into the fireproof rock wool, which not only protects the inserted materials, but also ensures the quality and efficiency of the construction.
