Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete hoisting tank technology, and in particular to a sealing structure for the discharge port of a hoisting tank. Background Technology
[0002] Cable cranes are key specialized equipment used in the pouring of dam concrete and the transport of auxiliary materials in water conservancy projects. To ensure the smooth pouring of dam concrete, a cable crane concrete hoisting tank (referred to as a "hoisting tank") is constructed to transport the concrete. The cable crane hoisting tank mainly consists of a tank body, an arc gate, two hydraulic accumulator cylinders, two arc gate opening and closing cylinders, a two-position four-way valve, and a self-locking device. During construction, the concrete is primarily transported by the hoisting tank, and the quality of the cable crane hoisting tank directly affects the overall construction of the dam project. Therefore, ensuring the safe and reliable operation of the hoisting tank is extremely important.
[0003] However, existing technologies have some problems: high-flow self-compacting concrete has the characteristics of large concrete slump and good fluidity. At the same time, after the hoisting tank has been used for a long time, the two arc gate opening and closing cylinders cannot drive the arc gate to close the hoisting tank outlet well. Therefore, when using a hoisting tank to pour high-flow self-compacting concrete, a small amount of leakage will occur at the outlet of the hoisting tank after the high-flow self-compacting concrete is loaded into the hoisting tank. Utility Model Content
[0004] To address the problems existing in the above-mentioned technologies, this utility model provides a sealing structure for the discharge port of a hoisting tank, which solves the problem of leakage at the discharge port of the hoisting tank after the high-flow self-compacting concrete is loaded into the hoisting tank.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A sealing structure for the discharge port of a hanging tank includes a soft annular conical sleeve fitted onto the discharge port of the hanging tank; the top of the soft annular conical sleeve is provided with an insertion cavity that mates with the discharge port of the hanging tank, and the sleeve is fitted onto the discharge port of the hanging tank through the insertion cavity. The soft annular conical sleeve wraps around the inner and outer walls of the hanging tank at the discharge port, while forming a sealing gasket with the bottom of the discharge port facing downwards.
[0007] Furthermore, the sealing structure for the discharge port of the hanging tank also includes an internal fixing component and an external fixing component for fixing the soft annular cone sleeve; the internal fixing component is a metal ring, and the inner wall of the soft annular cone sleeve is provided with a first groove for the metal ring to be inserted; the external fixing component is an elastic band, and the outer wall of the soft annular cone sleeve is provided with a second groove for the elastic band to be inserted.
[0008] Furthermore, the bottom of the soft annular cone sleeve is provided with an arc-shaped gap sealing strip, which is integrally formed with the soft annular cone sleeve.
[0009] The beneficial effects of this utility model are:
[0010] Effectively prevents material leakage: The inner and outer walls of the discharge port of the bucket are wrapped with a soft annular cone sleeve, and a sealing gasket is formed at the bottom. This increases the size of the bottom edge of the discharge port and avoids the gap between the discharge port and the arc gate, thus effectively preventing the leakage of high-flow self-compacting concrete during transportation.
[0011] Enhanced sealing: The soft annular cone sleeve is made of non-metallic materials (such as rubber or silicone rubber), which has good elasticity and sealing performance. It can fit tightly against the discharge port of the tank and further improve the sealing effect.
[0012] Preventing relative slippage: Through the design of internal fasteners (metal rings) and external fasteners (elastic bands), the soft annular cone sleeve is firmly fixed to the discharge port of the tank, avoiding relative slippage caused by vibration or concrete flow during transportation and ensuring the stability of the sealing structure.
[0013] Arc gate gap sealing: The bottom of the soft annular cone sleeve is equipped with an integrally formed arc gate gap sealing strip, which further prevents high-flow self-compacting concrete from leaking out from the gap between the two arc gates and enhances the overall sealing effect.
[0014] Easy to install and maintain: The soft annular cone sleeve has a simple design and is easy to install. The use of a metal ring and elastic band makes the fixing process more convenient. In addition, the non-metallic soft annular cone sleeve has a long service life and low maintenance costs.
[0015] In summary, this sealing structure, through its multiple sealing and fixing design, effectively solves the problem of material leakage during the transportation of high-flow self-compacting concrete, thereby improving construction efficiency and quality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0023] To address the issue of slight leakage at the discharge port of high-flow-rate self-compacting concrete (HCF) tanks after the concrete is poured, this embodiment provides a sealing structure for the HCF tank discharge port, such as... Figure 1 As shown, the sealing structure for the discharge port of the hanging tank includes a soft annular cone sleeve 2 fitted onto the discharge port 1 of the hanging tank; the soft annular cone sleeve 2 is made of a non-metallic material, such as rubber or silicone rubber. Figure 2 As shown, the soft annular cone sleeve 2 is an annular body with an upper diameter larger than the lower diameter, forming a cone-shaped structure.
[0024] like Figure 5 As shown, the top of the soft annular cone sleeve 2 is provided with an insertion cavity 3 for insertion into the discharge port 1 of the hanging tank; as Figure 1 As shown, after the soft annular cone sleeve 2 is fitted into the discharge port 1 of the bucket through the insertion cavity 3, the soft annular cone sleeve 2 wraps around the inner and outer walls of the bucket at the discharge port 1, and at the same time forms a sealing gasket 4 with the bottom of the discharge port 1 facing downward, thereby increasing the size of the lower edge of the bottom of the discharge port 1 and avoiding gaps between the discharge port 1 and the two arc gates 10, so as to realize the transportation of high-flow self-compacting concrete.
[0025] Furthermore, to prevent relative sliding between the soft annular cone sleeve 2 and the discharge port 1 of the hanging tank after installation; as Figure 3 and Figure 4 As shown, the sealing structure for the discharge port of the hanging tank also includes an internal fixing component and an external fixing component for fixing the soft annular cone sleeve 2.
[0026] like Figure 3 , Figure 4 and Figure 5As shown, the internal fixing component is a metal ring 5. The metal ring 5 is inserted into the tank through the feed port of the tank before the high-fluidity self-compacting concrete is loaded into the tank. The inner wall of the soft annular cone sleeve 2 is provided with a first groove 7 for the metal ring 5 to be inserted. The metal ring 5 is inserted into the first groove 7 by the deformation of the soft annular cone sleeve 2, thereby avoiding relative sliding between the inner wall of the soft annular cone sleeve 2 and the inner wall at the discharge port 1 of the tank.
[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the external fastener is an elastic band 6, and the outer wall of the soft annular cone sleeve 2 is provided with a second groove 8 that matches the elastic band 6. After the soft annular cone sleeve 2 is fitted onto the discharge port 1 of the hanging tank, the elastic band 6 is fastened to the outer wall of the soft annular cone sleeve 2 and inserted into the second groove 8, thereby preventing relative sliding between the outer wall of the soft annular cone sleeve 2 and the outer wall of the discharge port 1 of the hanging tank.
[0028] In addition, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, since the arc gate 10 at the bottom of the discharge port 1 of the hanging tank is a double-opening arc gate, in order to prevent the high-flow self-compacting concrete from leaking out through the gap between the two arc gates 10, an arc gate gap sealing strip 9 is also provided at the bottom of the soft annular cone sleeve 2 in this embodiment. The arc gate gap sealing strip 9 is integrally formed with the soft annular cone sleeve 2.
[0029] It should be noted that in actual engineering applications, the size of the sealing gasket 4 formed by the bottom of the soft annular cone sleeve 2 facing downwards can be determined based on the gap between the bottom lower edge of the discharge port 1 of the on-site hoisting tank and the two arc gates 10; at the same time, the size of the gap sealing strip 9 of the arc gate 10 can be determined based on the gap size between the two arc gates 10 on-site.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
