Description

Technical Field

[0001] This utility model relates to a liquid tanker unloading device, specifically to a control device for the liquid tanker unloading pipe installed in the liquid tanker to facilitate the on / off operation of unloading. Background Technology

[0002] Currently, in liquid tank semi-trailers, to ensure complete unloading of the material from the tank and avoid residual material, the unloading port is generally located in the lower part of the tank body, meaning the tank cross-section is circular, and the unloading port is at the bottom. A unloading pipe is connected to the unloading port, and a turbine butterfly valve is commonly used as the unloading control device on the unloading pipe. The turbine butterfly valve is usually installed near the unloading port at the bottom of the tank body, with the operating handle and turbine structure located directly below the tank body. In actual use, the operator needs to crawl under the vehicle to manually open and close the valve to control the flow of liquid during unloading.

[0003] Due to the narrow space under the tanker truck and the fact that the ground is often wet, muddy, or poses safety hazards, this structure has the following problems and shortcomings during use:

[0004] 1) The valve position is too low, and the operator must crawl under the vehicle to open and close it, which is inconvenient and labor-intensive.

[0005] 2) The space under the vehicle is limited, which can easily lead to safety risks such as collisions and scratches during operation. Utility Model Content

[0006] The main purpose of this utility model is to provide a liquid tanker unloading device, which aims to solve the following problems: the control of the liquid tanker unloading device needs to be carried out at the bottom of the liquid tank, which is inconvenient to operate and labor-intensive. At the same time, operating at the bottom of the liquid tank poses safety risks such as collision and scratches.

[0007] This utility model provides a liquid tanker truck unloading device, which is installed at the bottom of the tank body of the liquid tanker truck. It includes a discharge port located at the bottom of the tank body, and the discharge port is connected to a discharge pipe. A valve is installed on the discharge pipe, and the valve is connected to a rotary switch. The rotary switch is connected to a universal joint, and the other end of the universal joint is connected to an extension rod extending to one of the left or right sides. The extension rod extends to both sides of the chassis at the bottom of the tank body.

[0008] Preferably, the outer end of the extension rod is provided with an operating handle.

[0009] Preferably, the frame includes two longitudinal beams, one of which has a through hole, through which the extension rod passes and extends to the outside of the longitudinal beam.

[0010] Preferably, the unloading pipe includes a first pipe section extending downward, and a second pipe section extending to one of the left, right and rear sides is provided at the lower end of the first pipe section, and the valve is provided in the first pipe section.

[0011] Preferably, the valve is a turbine butterfly valve.

[0012] Preferably, the extension rod is a telescopic rod.

[0013] Compared with the prior art, the liquid tanker unloading device provided by this utility model has the following advantages:

[0014] In the aforementioned tank truck unloading device, the valve's rotary switch is connected to an extension rod via a universal joint. This extension rod extends to both sides of the vehicle frame, allowing operators to operate the unloading switch without crawling under the vehicle. This avoids operating in the confined space under the vehicle, reducing safety risks such as collisions, slips, and burns, and significantly improving operational convenience and safety. In this invention, the universal joint as a connecting component allows the extension rod to be flexibly adjusted according to the installation angle, reducing transmission resistance and mechanical wear, and extending the valve's service life. A handle is provided at the outer end of the extension rod, improving operational efficiency. The outer rotary handle provides more intuitive control, and the switching action is smooth and easy, shortening unloading preparation time and improving overall operational efficiency. Finally, the universal joint and extension rod can be designed as independent modules, resulting in a simple structure, convenient disassembly and maintenance, and low replacement costs.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] This embodiment provides a liquid tanker truck unloading device. This device is installed at the bottom of the tank body 7 of the liquid tanker truck and includes a discharge port located at the bottom of the tank body 7, specifically at the lowest point of the tank body 7 corresponding to the middle position of the vehicle frame. The discharge port is connected to a discharge pipe. A valve is installed on the discharge pipe, and the valve is connected to a rotary switch 2. The rotary switch 2 is connected to a universal joint 6. The other end of the universal joint 6 is connected to an extension rod 3 extending to one of the left or right sides, with the extension rod 3 extending to both sides of the vehicle frame below the tank body 7.

[0023] The aforementioned tanker truck unloading device requires opening the valve switch when unloading is needed. Conventional tanker trucks require personnel to crawl under the vehicle to operate the valve switch. However, in this embodiment, workers can stand on both sides of the vehicle frame to operate the extension rod 3. Workers only need to rotate the extension rod 3, and the rotation is transmitted to the valve's rotary switch 2 through the universal joint 6, thus opening or closing the valve. Workers no longer need to crawl under the vehicle to operate the valve.

[0024] Specifically, in this embodiment, when operating the extension rod 3, it is necessary to rotate the extension rod 3. In order to facilitate the rotation operation, the outer end of the extension rod 3 is provided with an operating handle 5. The handle 5 can be a horizontal plate or horizontal bar perpendicular to the extension rod 3, or it can be a steering wheel-type control panel provided at the end of the extension rod 3.

[0025] Specifically, in this embodiment, the tanker truck is a semi-trailer or a main vehicle. The frame of the semi-trailer or part of the main vehicle generally includes two I-beams 4, with a crossbeam between the two longitudinal beams 4. In this type of frame, the unloading port must be located between the two longitudinal beams 4. The setting of the longitudinal beams 4 will interfere with the setting of the extension rod 3. To solve the interference problem of the longitudinal beams 4, one of the longitudinal beams 4 is provided with a through hole, and the extension rod 3 passes through the through hole and extends to the outside of the longitudinal beam 4.

[0026] Specifically, in this embodiment, the unloading pipe includes a first pipe section 8 extending downward, and a second pipe section 9 extending to one of the left and right sides and the rear side is provided at the lower end of the first pipe section 8. The valve is provided in the first pipe section 8.

[0027] Specifically, in this embodiment, the valve is a turbine butterfly valve 1.

[0028] Specifically, in this embodiment, the extension rod 3 extends from the middle of the frame to at least one side on the left and right. When the extension rod 3 is extended, it is convenient for the operator to operate. However, the extended extension rod 3 increases the risk of being damaged by collision. In order to avoid collision problems, the extension rod 3 can be set in the longitudinal beam 4 of the I-beam, that is, in the groove formed between the upper and lower strips on the outer side of the web of the longitudinal beam 4. At the same time, the extension rod 3 can also be set as a telescopic rod, that is, it extends when in use and retracts to fit against the web of the longitudinal beam 4 when not in use. The telescopic setting of the extension rod 3 is a non-rotatable telescopic setting. For example, the extension rod 3 is composed of a square steel tube and an inner rod or inner tube inserted into the steel tube in the direction of insertion.

[0029] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
