Description

Technical Field

[0001] This utility model belongs to the field of fireproof coating production technology, and specifically relates to a placement rack. Background Technology

[0002] Fire-retardant paint buckets are specialized sealed containers used to hold fire-retardant coatings (such as intumescent fire-retardant coatings for steel structures and fire-retardant coatings for cables). They are usually made of metal or high-strength plastic and have features such as leak-proof, corrosion-resistant, and flame-retardant properties. They are widely used in fire protection engineering in construction, power, and transportation. Fire-retardant paint bucket racks are storage equipment specifically designed for the safe storage and management of these paint buckets. They are generally made of metal with a multi-layer design, allowing paint buckets to be neatly arranged to prevent rolling, leakage, and collisions. This facilitates transportation, retrieval, and on-site management, improving construction efficiency and operational safety.

[0003] Existing fire-retardant paint bucket storage racks mostly adopt a fixed multi-layer storage plate structure. When using hoisting equipment (such as overhead cranes and slings) to lift heavy fire-retardant paint buckets (especially large buckets) to the upper storage plate, the hoisting ropes or slings will be obstructed and interfered with by the upper plates, resulting in obstructed vision and difficulty in positioning during the hoisting process. The fire-retardant paint buckets cannot be placed directly and accurately in the center of the storage plate. They can only be placed at the edge first and then manually pushed into the middle by personnel. Personnel need to push the buckets at close range, which poses a risk of being squeezed, slipping, or being injured by the bucket tipping over. Moreover, it is more strenuous to push heavy paint buckets, increasing the burden on workers. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a placement rack that allows the upper plate to be temporarily rotated open during hoisting, creating vertical passage space for the hoisting ropes and fire-retardant paint buckets. This enables the fire-retardant paint buckets to be directly, accurately, and stably lowered into the center of the lower placement plate without manual pushing, avoiding close contact between personnel and heavy objects, and reducing the burden on workers.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a placement frame, including a support frame, with multiple placement frame plates arranged at the upper part of the support frame, and multiple rotating placement plates rotatably arranged inside each placement frame plate via a rotating column. Sliding frames are respectively arranged in the mounting openings on the front and rear sides of each placement frame plate, and limiting plates are slidably arranged inside each sliding frame plate. Multiple limiting plates are respectively in contact with the lower side of adjacent rotating placement plates. A rotation drive mechanism for driving the rotating placement plates to rotate is arranged on the right side of the placement frame plate, and a movement drive mechanism for driving the limiting plates to move is arranged on the left side of the placement frame plate.

[0006] The rotary drive mechanism includes a drive box located on the right side of each placement frame plate. Each drive box contains a rotating column, and multiple bevel gears are fixedly mounted on the outer arc surface of each rotating column. A bevel gear is located on the right side of each rotating column. The multiple bevel gears mesh with adjacent bevel gears. A drive unit is located on the rear side of each placement frame plate to drive the rotating column. Each drive unit includes a motor located on the rear side of the multiple placement frames. The output shaft of the motor is connected to the adjacent rotating column via a coupling. The moving drive mechanism includes a slide rail located on the left side of each placement frame plate. Each slide rail contains two sliding connecting plates. The outer surfaces of two adjacent left and right limiting plates are connected to the inner surfaces of adjacent sliding connecting plates. A bidirectional lead screw is rotatably mounted inside each slide rail. Two sliding connecting plates located within the same slide rail are threaded to the corresponding front and rear ends of adjacent bidirectional lead screws. A drive unit is located on the rear side of each slide rail. Each drive unit includes a motor located on the rear side of the multiple slide rails. The output shaft of the motor is connected to the rear end of the adjacent bidirectional lead screw via a coupling.

[0007] As a further improvement of this utility model, a placement base plate is provided at the lower end of the inner side of the support frame, and the support frame and the placement base plate are fixed together by welding.

[0008] As a further improvement of this utility model, mounting plates are provided on the left and right sides of the support frame, with the two mounting plates corresponding to each other, and each mounting plate has multiple mounting holes inside.

[0009] As a further improvement of this utility model, the upper end of the rotating placement plate is provided with multiple anti-slip protrusions, and the upper end of each placement frame plate is provided with a protective plate. The placement frame plates and the placement plates are fixed together by welding.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by controlling the opening of all motors one and two to run in reverse, the rotating placement plate is controlled to rotate, and the limiting plates on both sides are brought closer together under the restriction of the sliding frame, so that they contact the lower side of the rotating placement plate. The fireproof paint bucket on the rotating placement plate is stably supported by the limiting plates and the sliding frame. Then, personnel use hoisting equipment to hoist the fireproof paint bucket from the top to the two rotating placement plates at the bottom. The upper plate can be temporarily rotated open to make vertical passage space for the hoisting rope and the fireproof paint bucket, so that the hoisted fireproof paint bucket can be directly, accurately and stably dropped into the center of the lower placement plate without manual pushing, avoiding close contact with heavy objects and reducing the burden on workers.

[0011] Secondly, the anti-slip protrusions on the rotating placement plate can significantly increase the contact friction with the bottom of the fireproof coating bucket, effectively preventing the bucket from sliding, misaligning or shifting due to vibration, tilting or external force during hoisting, placement, movement or transportation, ensuring that the bucket can be stably and accurately placed in the center of the placement plate.

[0012] Third, the protective plates installed on the placement frame can effectively limit the lateral movement and accidental tipping of the fire-retardant paint buckets on the placement rack, prevent the buckets from shifting or tipping over due to vibration, collision or uneven ground, and ensure that the buckets are always stably positioned in the designated location to avoid leakage or damage.

[0013] Fourth, the mounting plates with multiple mounting holes on the left and right sides of the support frame can be firmly fixed to the ground, wall or equipment base with bolts or other fasteners, effectively enhancing the stability and anti-tipping ability of the overall structure, preventing displacement or shaking during hoisting, handling or use on uneven ground, and ensuring the safe and orderly storage of fireproof paint buckets.

Detailed Implementation

[0017] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0018] like Figure 1 , 2 As shown in Figure 3, a placement rack includes a support frame 101. Multiple placement frame plates 103 are arranged at the upper interior of the support frame 101. Multiple rotating placement plates 201 are rotatably arranged inside each placement frame plate 103 via a rotating column. Sliding frames 208 are respectively arranged in the mounting openings on the front and rear sides of each placement frame plate 103. Limiting plates 209 are slidably arranged inside each sliding frame 208. Multiple limiting plates 209 respectively contact the lower side of adjacent rotating placement plates 201. A rotation drive mechanism for driving the rotating placement plates 201 to rotate is arranged on the right side of the placement frame plate 103, and a movement drive mechanism for driving the limiting plates 209 to move is arranged on the left side of the placement frame plate 103. A placement base plate 102 is arranged at the lower interior of the support frame 101.

[0019] like Figure 1 As shown, mounting plates 301 are respectively provided on the left and right sides of the support frame 101. Each mounting plate 301 has multiple mounting holes 302 inside. The mounting plates 301 with multiple mounting holes 302 provided on the left and right sides of the support frame 101 can be used to firmly fix the support frame 101 to the ground or equipment base by bolts or other fasteners, so as to achieve stable installation and convenient connection.

[0020] like Figure 2 , 3 As shown in Figure 4, the rotary drive mechanism includes a drive box 203 located on the right side of each placement frame 103. Each drive box 203 has a rotating column 213 rotatably mounted inside. Multiple bevel gears 211 are fixedly mounted on the outer arc surface of each rotating column 213. A bevel gear 212 is located on the right side of each rotating column. The multiple bevel gears 211 mesh with adjacent bevel gears 212. A drive unit 204 for driving the rotating column 213 is located on the rear side of each placement frame 103. The drive unit 204 includes a motor 204 located on the rear side of each placement frame 103. The output shaft of the motor 204 is connected to the adjacent rotating column 213 via a coupling. The moving drive mechanism includes... On the left side of each placement frame plate 103, there is a slide rail 205. Inside each slide rail 205, there are two sliding connecting plates. The outer sides of two adjacent left and right limiting plates 209 are respectively connected to the inner sides of the adjacent sliding connecting plates 207. Inside each slide rail 205, there is a bidirectional lead screw 210. The two sliding connecting plates 207 located inside the same slide rail 205 are respectively threaded to the front and rear corresponding ends of the adjacent bidirectional lead screw 210. A second drive unit is provided on the rear side of each slide rail 205. The second drive unit includes a second motor 206 provided on the rear side of multiple slide rails 205. The output shaft of the second motor 206 is connected to the rear end of the adjacent bidirectional lead screw 210 through a coupling.

[0021] Initially, all rotating placement plates 201 are in a horizontal working position, supported by limiting plates 209, and used to carry fire-retardant paint buckets. When placing a bucket on a certain layer (especially a lower layer), to avoid obstruction of the hoisting path by the upper structure, the operator or control system first starts all "motors 206" located on the upper layer and reverses their operation. The output shaft of motor 206 drives the bidirectional lead screw 210 to rotate, which, through the lead screw nut, drives the sliding connecting plates 207 on both sides to move synchronously outward (away from each other) under the guidance of the sliding frame 208. This causes the limiting plates 209 connected to the sliding connecting plates 207 to gradually disengage from their supporting contact with the lower surface of the rotating placement plate 201, thus releasing the placement plate for that layer.

[0022] Subsequently, the corresponding level's "Motor 1 204" is activated and reversed. The output shaft of Motor 1 204 drives the bevel gear 1 on its rotating column to rotate. Since bevel gear 1 meshes with bevel gear 2 on the adjacent rotating column, forming a bevel gear transmission group, it drives the entire rotating placement plate 201 to rotate smoothly 90 degrees around the axis of the rotating column, changing from a horizontal state parallel to the placement frame plate 103 to an upright state vertically parallel to the placement frame plate 103. At this time, the rotating placement plate 201 of this level completely "gives up" the vertical space and no longer obstructs the hoisting path.

[0023] Start the bottom layer "Motor 204" to run in the forward direction. Through the same bevel gear transmission mechanism, drive the rotating placement plate 201 of this layer to rotate 90 degrees in the reverse direction, return it to a horizontal state, keep it parallel to the placement frame plate 103, and prepare it to carry the barrel.

[0024] Next, the bottommost "motor 206" is started to run in the forward direction. The bidirectional lead screw 210 drives the sliding connecting plates 207 on both sides to move closer to each other. Under the guidance of the sliding frame 208, the limiting plate 209 moves towards the center in sync until it is tightly supported under the rotating placement plate 201, which has been rotated back to the horizontal position, forming a stable load-bearing structure.

[0025] Subsequently, the power to motor 206 on this floor is cut off. Although motor 206 loses its self-locking ability after the power is cut off, the weight of the rotating placement plate 201 and the fireproof paint bucket it carries is now fully borne by the mechanical structure of the limiting plate 209 and the sliding frame 208, ensuring stable and reliable bearing and preventing it from falling or shifting.

[0026] Afterwards, the operator repeats the above process—releasing and rotating the upper rotating placement plate 201 to the vertical clearance position in sequence, then hoisting the fireproof coating buckets down layer by layer, and restoring the rotating placement plate 201 to the horizontal bearing state layer by layer to complete the placement of the fireproof coating.

[0027] According to another embodiment of the present invention, such as Figure 1 ,3 As shown in Figure 4, the upper end of the rotating placement plate 201 is provided with multiple anti-slip protrusions 202, and the upper end of each placement frame plate 103 is provided with a protective plate 104. The anti-slip protrusions 202 on the rotating placement plate 201 can increase the friction with the bottom of the fire retardant paint bucket, preventing the bucket from sliding or shifting during placement or movement. The protective plate 104 on the placement frame plate 103 can limit the lateral displacement or tipping of the bucket, ensuring its stable positioning and improving placement safety and stability.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
