Description

Technical Field

[0001] This utility model relates to the field of loading arm technology, specifically a telescopic vertical tube type loading arm. Background Technology

[0002] In the fields of petrochemicals and liquid storage and transportation, loading arms are key equipment for loading and unloading liquid media such as oil and chemicals. Traditional telescopic vertical loading arms usually include an outer tube and an inner tube (lifting vertical tube). The inner tube can extend and retract to accommodate tank trucks or storage tanks of different heights. However, after the loading and unloading operation is completed, a small amount of liquid media may remain on its surface or at its port during the retraction process. This residual liquid will drip onto the ground or equipment surface, which not only wastes the media but may also pollute the environment and even cause safety hazards.

[0003] Existing loading arms typically lack effective residual liquid recovery devices. Some improved solutions use fixed receiving trays or guide channels, but due to the motion characteristics of telescopic vertical pipes, fixed structures are difficult to adapt to the expansion and contraction of the lifting vertical pipes, resulting in poor residual liquid recovery. In addition, traditional residual liquid collection mechanisms are often complex in structure and inconvenient to maintain, making it difficult to meet the efficiency and reliability requirements of actual operations.

[0004] Therefore, there is an urgent need for a telescopic vertical tube loading arm that can automatically adapt to the telescopic movement of the lifting vertical tube, efficiently recover residual liquid, and has a simple structure and convenient maintenance, in order to solve the problem of resource waste and environmental pollution caused by residual liquid leakage in the existing technology. Utility Model Content

[0005] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a telescopic vertical loading arm that can recover residual liquid on the inner wall of the vertical pipe and avoid pollution of the site when the vertical pipe is not transporting fluid.

[0006] The technical problem to be solved by this utility model is achieved through the following technical solution: a telescopic vertical tube loading arm, which includes an outer tube and a lifting vertical tube, the lifting vertical tube being concentrically arranged inside the outer tube, and a residual liquid recovery mechanism being provided on the outer circumferential surface of the outer tube.

[0007] The residual liquid recovery mechanism includes a telescopic power mechanism mounting plate fixed on the outer circumferential surface of the outer tube, a telescopic power mechanism vertically fixed on the telescopic power mechanism mounting plate, a contact block fixedly mounted on the power output end of the telescopic power mechanism, an installation shaft hinged to the outer circumferential surface of the outer tube below the contact block, a contact plate for abutting against the contact block horizontally fixed on the outer circumferential surface of the installation shaft facing the axis of the outer tube, a connecting plate fixedly mounted on the bottom outer circumferential surface of the installation shaft, and a receiving box fixedly mounted on the bottom outer wall of the connecting plate. The top surface of the receiving box is located directly below the outer tube and has a receiving groove for receiving residual liquid dripping from the lifting and lowering pipe.

[0008] The residual liquid recovery mechanism also includes a reset mechanism, which includes a reset elastic element. One end of the reset elastic element is fixed to the outer circumferential surface of the outer tube below the contact plate, and the other end is fixed to the side wall of the connecting plate facing the outer tube.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the telescopic vertical tube loading arm described above, wherein the telescopic power mechanism mounting plate is horizontally set, and the telescopic power mechanism is vertically fixed on the telescopic power mechanism mounting plate.

[0010] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned telescopic vertical tube loading arm, wherein the reset elastic element is a spring.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are:

[0012] (1) By setting a residual liquid recovery mechanism on the outer pipe of the loading arm, the residual liquid dripping can be automatically collected when the lifting vertical pipe retracts and collected into the receiving groove of the receiving box, which effectively avoids liquid dripping onto the ground or equipment surface, reduces media waste and environmental pollution, and meets environmental protection requirements.

[0013] (2) The residual liquid recovery mechanism uses a telescopic power mechanism to drive the contact block, and with the hinged mounting shaft and reset elastic element, the receiving box can automatically adjust its position with the extension and retraction of the lifting vertical pipe, ensuring that it is always located directly below the dripping liquid, without the need for manual intervention, thus improving the automation level of the operation.

[0014] (3) The reset elastic element can automatically reset itself to the initial position after the receiving box completes the collection of residual liquid, ensuring the stability and reliability of the mechanism in long-term operation. Its structure is simple, easy to install and disassemble, and highly practical. Attached Figure Description

[0019] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0020] Example 1, referring to Figure 1-2 A telescopic vertical tube loading arm includes an outer tube 1 and a lifting vertical tube 2. The tops of the outer tube 1 and the lifting vertical tube 2 are fixed to external oil conveying equipment. For example, the top of the outer tube 1 is fixed to the outer shell (not shown) of the oil conveying arm (not shown in the figure), and the top of the lifting vertical tube 2 is fixed to the telescopic mechanism of the oil conveying arm. The lifting vertical tube 2 is concentrically arranged inside the outer tube 1, and a residual liquid recovery mechanism is provided on the outer circumferential surface of the outer tube 1.

[0021] The residual liquid recovery mechanism includes a telescopic power mechanism mounting plate 3 fixed to the outer circumference of the outer pipe 1. The telescopic power mechanism mounting plate 3 is formed into a roughly square plate structure. The telescopic power mechanism mounting plate 3 is horizontally arranged, and a telescopic power mechanism 4 is vertically fixed on the telescopic power mechanism mounting plate 3. The telescopic power mechanism 4 is vertically fixed on the telescopic power mechanism mounting plate 3. The telescopic power mechanism 4 can be a hydraulic telescopic rod or a cylinder. Its hydraulic power source and air source can be supplied by the pump station or air source power source matched with the oil delivery arm. A contact block 5 is fixedly installed on the power output end of the telescopic power mechanism 4. The contact block 5 is formed into a roughly hemispherical block structure. The arc surface of the hemispherical block structure faces down and is directly opposite the contact plate 6 below. The outer pipe 1 below the contact block 5... A mounting shaft 7 is hinged to the outer circumferential surface. The mounting shaft 7 is a horizontally arranged shaft structure. A contact plate 6 for abutting against the contact block 5 is horizontally fixedly installed on the outer circumferential surface of the mounting shaft 7 on the side facing the axis of the outer tube 1. The contact plate 6 is a roughly horizontal plate structure, and its top surface is used to abut against the contact block 5. A connecting plate 8 is fixedly installed on the bottom outer circumferential surface of the mounting shaft 7. The connecting plate 8 is a vertically arranged square plate structure. A receiving box 9 is fixedly installed on the bottom outer wall of the connecting plate 8. The receiving box 9 is a roughly square box structure. The top surface of the receiving box 9 is located directly below the outer tube 1 and has a receiving groove for receiving the residual dripping liquid from the lifting vertical tube. The receiving groove is a square groove, and its design purpose is to collect and recover the fluid dripping from the lifting vertical tube 2.

[0022] The residual liquid recovery mechanism also includes a reset mechanism, which includes a reset elastic element 10. One end of the reset elastic element 10 is fixed on the outer circumferential surface of the outer tube 1 below the contact plate 6, and the other end is fixed on the side wall of the connecting plate 8 facing the outer tube 1. The reset elastic element 10 is a spring.

[0023] The telescopic vertical loading arm in Example 1 is used as follows:

[0024] (1) Initial state: When the loading arm is in a non-working state, the external oil delivery arm drives the lifting vertical pipe 2 to retract into the outer pipe 1. At this time, the receiving box 9 of the residual liquid recovery mechanism maintains the initial position under the action of the reset elastic element 10, that is, the receiving box 9 is located directly below the outer pipe 1, so as to receive the fluid dripping from the inner wall of the lifting vertical pipe 2. At this time, the telescopic power mechanism 4 is in a retracted state.

[0025] (2) Loading operation: At this time, the external oil delivery arm drives the lifting pipe 2 to extend from the bottom end of the outer pipe 1 and insert it into the loading port of the tank truck or storage tank. During this process, the telescopic end of the telescopic power mechanism 4 is extended by the external power source, causing the contact block 5 to apply a thrust to the top surface of the contact plate 6, thereby causing the receiving box 9 to swing counterclockwise around the axis of the mounting shaft 7. On the one hand, this can avoid physical interference between the lifting pipe 2 and the receiving box 9 during the vertical movement, and on the other hand, it can allow the residual liquid accumulated in the receiving box 9 to be poured into the loading port of the tank truck or storage tank.

[0026] (3) After loading: The lifting pipe 2 begins to retract upwards back into the outer pipe 1. During this process, the telescopic end of the telescopic power mechanism 4 is driven to retract by the external power source. At this time, the elastic potential energy of the reset elastic element 10 causes the connecting plate 8 and the receiving box 9 to rotate around the mounting shaft 7 on one side of the outer pipe 1 until the receiving box 9 returns to the initial position and collects the remaining liquid on the inner wall of the lifting pipe 2 again until the next loading process, when the remaining liquid is transferred to the next tank car or storage tank.
