Description

Technical Field

[0001] The utility model relates to a sealing protection device, in particular to a rubber sealing protection device for a gate, belonging to the technical field of hoist gates. Background Art

[0002] The gate of a hoist, also known as a sluice gate, is a large-scale hydraulic machinery product, which plays a crucial role in the normal operation of hydraulic structures. In addition to meeting the design requirements of general lifting machinery, it also needs to be safe, reliable, and flexible and convenient to operate. Since hoist gates are usually used in the construction of waterway partitions, the sealing performance of the gate itself is particularly important.

[0003] In the prior art, the sealing of the gate mainly relies on the fitting of the sealing strip or sealing rubber with the door stop to achieve the purpose of waterproof sealing. In the actual use process, the gate plate usually uses a screw drive to slide up and down, and during the sliding process of the gate plate, the sealing strip or sealing rubber will rub against the door stop, and at this time, the sealing rubber is extremely likely to fall off or displace, thereby greatly reducing the service life of the gate.

[0004] Therefore, it is urgent to improve the rubber sealing protection device for the gate to solve the above problems. Summary of the Utility Model

[0022] The following will describe in detail the embodiments of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0023] As Figures 1-4As shown in the figure, the rubber sealing and protecting device for the gate provided in this embodiment includes a door panel 1. A plurality of baffles 2 are fixedly arranged on the edge of the door panel 1. A P-shaped rubber 3 is fixedly arranged on one side of the door panel 1 close to the baffle 2. One side of the P-shaped rubber 3 abuts against the door panel 1. The thick end of the P-shaped rubber 3 is used to contact and seal with the door stop. The plurality of baffles 2 are connected end to end and surround the outside of the P-shaped rubber 3. The P-shaped rubber 3 is fixedly arranged inside the square formed by the baffles 2, which can prevent the P-shaped rubber 3 from shifting when it rubs against the door stop. A plurality of pressing strips 4 are fixedly installed on the side of the P-shaped rubber 3 away from the door panel 1. The plurality of pressing strips 4 are connected end to end and surround one side of the thin end of the P-shaped rubber 3. The pressing strips 4 fix the thin end of the P-shaped rubber 3;

[0024] Among them, when the door panel 1 slides upward, the P-shaped rubbers 3 at the upper and lower ends will generate a downward frictional force with the door stop. The upper P-shaped rubber 3 is fastened by the pressing strip 4, and the lower P-shaped rubber is blocked by the baffle 2. Conversely, when the door panel 1 slides downward. By fixing the thin end of the P-shaped rubber 3 with the pressing strip 4, when the door panel 1 works, the convex part of the thick end of the P-shaped rubber 3 contacts the door stop to seal the gate. The P-shaped rubber 3 is surrounded by a plurality of baffles 2 connected end to end to protect it, preventing it from shifting during the sliding process of the door panel 1, thereby greatly reducing the probability of the P-shaped rubber 3 running off and being damaged, and thus greatly extending the service life of the gate.

[0025] Furthermore, Figures 1-3 As shown in the figure, a plurality of uniformly distributed threaded holes 5 are formed in the door panel 1, and a plurality of uniformly distributed mounting holes 6 are formed in the pressing strip 4. The mounting holes 6 correspond to the threaded holes 5 one by one. This stable connection method ensures that during daily use, the pressing strip 4 will not easily loosen, shift or fall off, making the door panel 1 and the pressing strip 4 form a stable overall structure. The uniformly distributed mounting holes 6 and threaded holes 5 make the force more uniform during connection; this can avoid structural deformation, damage or connection failure caused by excessive local force;

[0026] At the same time, Figures 1-4 As shown in the figure, a fastening bolt 7 is rotationally arranged inside the mounting hole 6 through threads. The fastening bolt 7 penetrates through the P-shaped rubber 3 and the pressing strip 4 and extends into the threaded hole 5, forming a through-type connection structure. Compared with simply relying on the connection between the pressing strip 4 and the door panel 1, this through-type connection greatly enhances the strength and stability of the connection. Such a connection method can ensure that the pressing strip and the rubber still maintain a firm connection in a long-term vibrating working environment and will not easily become loose;

[0027] After the fastening bolt 7 is tightened, a certain pressure can be exerted on the P-shaped rubber 3, making the P-shaped rubber 3 fit more closely to the door panel 1, thereby improving the sealing performance; during long-term use, due to changes in the external environment, the sealing material may become loose, and the fixing function of the fastening bolt 7 can effectively inhibit this loosening and maintain the stability of the seal; by installing the fastening bolt 7 through thread rotation, the operation is relatively simple, and the installer can quickly install the bead 4 and the P-shaped rubber 3 on the door panel 1, improving the installation efficiency;

[0028] In the process of large-scale production, this simple installation method can significantly shorten the production cycle, reduce production costs, and facilitate disassembly and maintenance: when it is necessary to repair, replace, or clean the components, simply rotate the fastening bolt 7 in the reverse direction to remove the bead 4 and the P-shaped rubber 3 from the door panel 1. The operation is convenient and fast. This detachable connection method allows the maintenance personnel to easily complete the replacement work, reducing the maintenance time and cost.

[0029] In addition, as Figure 1 、 Figure 2 and Figure 4 shown, the protruding height of the baffle 2 is lower than the protruding height of the thick end of the P-shaped rubber 3. On the one hand, it can make the thick end of the P-shaped rubber 3 contact the door stop first during the downward sliding of the door panel 1. On the other hand, it can also prevent the door panel 1 from being too close to the door stop and causing the baffle 2 to collide or rub with it, which is beneficial to reducing abnormal sounds or noises generated during the use of the gate.

[0030] Furthermore, as Figure 2 and Figure 4 shown, air holes 8 are provided inside the P-shaped rubber 3. When the door panel 1 is impacted by an external force, the air holes 8 in the P-shaped rubber 3 can play a buffering role. Since the gas is compressible, when under pressure, the gas in the air holes is compressed, absorbing and dispersing the impact force. When the door panel is closed, the P-shaped rubber 3 is squeezed, and the presence of the air holes 8 makes the overall structure of the P-shaped rubber 3 softer and more elastic, making it easier to bend and deform. The air holes 8 enable the rubber to better fit the door panel and the door frame, thereby enhancing the sealing effect.

[0031] As Figures 1-4 shown, the principle of the rubber sealing and protection device for the gate provided in this embodiment is as follows:

[0032] After the fastening bolt 7 is tightened, a certain pressure can be exerted on the P-shaped rubber 3, making the P-shaped rubber 3 fit more closely on the door panel 1. When the door panel 1 slides upward, the P-shaped rubbers 3 at the upper and lower ends will generate a downward frictional force with the door stopper. The P-shaped rubber 3 at the upper end is fastened by the pressing strip 4, and the P-shaped rubber at the lower end is blocked by the baffle 2. Conversely, when the door panel 1 slides downward. By fixing the thin end of the P-shaped rubber 3 with the pressing strip 4, when the door panel 1 works, the protruding part of the thick end of the P-shaped rubber 3 contacts the door stopper to seal the gate. The P-shaped rubber 3 is surrounded by a number of baffles 2 connected end to end to protect it, preventing it from shifting during the sliding of the door panel 1, thereby greatly reducing the probability of the P-shaped rubber 3 running off and being damaged, and thus greatly extending the service life of the gate.
