Description

Technical Field

[0001] This utility model relates to the technical field of tank semi-trailers, specifically to a top reinforcement structure for a tank semi-trailer transporting corrosive materials. Background Technology

[0002] Tanker semi-trailers are specialized vehicles used for transporting liquids, gases, or bulk materials. Their core feature is the use of a tank-shaped container as the cargo carrier, offering advantages such as high efficiency, safety, and environmental friendliness. The cargo-carrying portion of the tank structure is a sealed tank made of high-strength steel or stainless steel. The interior can be designed with baffles, heating, or insulation layers depending on the cargo characteristics. The dedicated chassis is equipped with a reinforced frame, suspension system, and braking system. Safety features include emergency pressure relief valves and breather valves to prevent damage from overpressure or negative pressure. Some models also feature anti-corrosion coatings or linings.

[0003] In the process of transporting corrosive goods using tank semi-trailers, a top reinforcement structure is required. Utility model patent CN220742842U discloses a top reinforcement structure for an aluminum alloy tank semi-trailer, relating to the field of tank semi-trailers. It includes: a semi-trailer body; a tank body fixed to the top of the semi-trailer body; a rubber pad fixed to the top of the tank body; a top connected to the top of the rubber pad, with its bottom connected to the top of the tank body; a sealing cap disposed on the top of the top of the sealing cap; and two fixing plates, each fixed to one side of the top of the rubber pad. The top reinforcement structure for the aluminum alloy tank semi-trailer provided by this utility model effectively limits and fixes the sealing cap of the tank semi-trailer, thereby greatly increasing the stability of the sealing cap.

[0004] However, the cap reinforcement structure is usually installed by bolts and nuts. During the operation of the tank semi-trailer, the vibration can easily cause the nuts to loosen, resulting in the cap becoming loose and thus a poor seal. Therefore, a cap reinforcement structure for tank semi-trailers transporting corrosive materials is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a top reinforcement structure for a semi-trailer transporting corrosive goods in tanks. This structure has advantages such as preventing the nuts from loosening during operation, and solves the problem that common top reinforcement structures are prone to loosening of the locking nuts during the vibration generated during the operation of the semi-trailer.

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

[0007] A top reinforcement structure for a semi-trailer transporting corrosive materials includes a semi-trailer body, a storage tank fixedly mounted on the top of the semi-trailer body, a top fixedly mounted on the top of the storage tank, a connecting ring plate fixedly mounted on the top of ...

[0008] The reinforcing component includes a reinforcing cover fitted onto the top of the sump. A limiting tube is fixedly installed on the inner top wall of the reinforcing cover. The limiting tube is aligned with a locking nut. The bottom of the limiting tube has an internal hexagonal groove that matches the locking nut.

[0009] Furthermore, a retaining ring is fixedly installed on the top of the storage tank, the retaining ring being adapted to the reinforcing cover, and the reinforcing cover being sleeved on the surface of the retaining ring.

[0010] Furthermore, a limiting ring plate is fixedly installed at the bottom of the reinforcing cover, and a protective outer frame is fixedly installed at the top of the storage tank, with the top of the tank located inside the protective outer frame.

[0011] Furthermore, a telescopic rod is fixedly installed on the inner side wall of the protective frame, and a limit plate is fixedly installed on the movable end of the telescopic rod.

[0012] Furthermore, the bottom of the limiting pressure plate is in contact with the top of the limiting ring plate, and one side of the limiting pressure plate is in contact with the surface of the reinforcing cover.

[0013] Furthermore, a compression spring is fitted onto the surface of the telescopic rod. One side of the compression spring is fixedly connected to the inner wall of the protective outer frame, and the other side of the compression spring is fixedly connected to one side of the limiting pressure plate.

[0014] Furthermore, a sealing plug is fixedly installed at the bottom of the cap, and a sealing ring is embedded on the surface of the sealing plug, which is compatible with the top of the sump.

[0015] Furthermore, a baffle plate is fixedly installed on the inner wall of the storage tank, and a connecting hole is opened on one side of the baffle plate.

[0016] Compared with the prior art, this utility model provides a top reinforcement structure for a semi-trailer transporting corrosive goods in tanks, which has the following beneficial effects:

[0017] 1. The reinforced structure of the tank top of this corrosive material tank transport semi-trailer solves the problem of common tank top reinforcement structures, which typically use bolts and nuts to install the cover. During the operation of the tank transport semi-trailer, the vibration generated can easily cause the nuts to loosen, leading to a loose cover and thus a poor seal.

[0018] 2. The top reinforcement structure of the corrosive material tank semi-trailer is achieved by setting a protective outer frame on the top of the storage tank, setting a telescopic rod on the inner side wall of the protective outer frame, setting a limiting pressure plate at the movable end of the telescopic rod, limiting the reinforcement cover by a retaining ring to prevent the reinforcement cover from moving laterally, and pushing the limiting pressure plate towards the reinforcement cover by a compression spring, so that the limiting pressure plate limits the reinforcement cover and the limiting ring plate to prevent the reinforcement cover from moving upward.
