Description

Technical Field

[0001] This utility model relates to the field of loading arm technology, and in particular to a top-loading loading arm for alcohol and ether chemicals. Background Technology

[0002] Alcohol ether chemicals are volatile, flammable, explosive, highly penetrating, and of medium viscosity. Loading arms are required for the transfer and unloading of alcohol ether chemicals.

[0003] However, when existing loading arms used for alcohol and ether chemicals are not in use, their nozzles are often directly exposed to the environment without a sealing device. This makes it easy for external impurities to enter the loading arm and affect its normal operation. Therefore, this invention proposes a top-loading loading arm specifically for alcohol and ether chemicals to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing a special top loading arm for alcohol and ether chemicals.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A top-loading loading arm for alcohol and ether chemicals, comprising:

[0007] Crane tube body;

[0008] A sealing cap is detachably and airtightly connected to the port of the loading arm body;

[0009] The loading and unloading assembly includes a right-angle rod fixedly installed on the surface of the sealing cap. A fixing cylinder is slidably sleeved at one end of the right-angle rod away from the sealing cap. A fixing box is rotatably installed at the other end of the fixing cylinder, and the fixing box is detachably connected to the surface of the loading arm body. A spring is connected between the inner top of the fixing cylinder and the end of the right-angle rod away from the sealing cap.

[0010] The mounting assembly is used to secure the mounting box to the surface of the loading arm body.

[0011] Preferably, the mounting assembly includes a double-headed worm gear rotatably mounted inside a fixed box. Two worm wheels mesh in opposite directions on the outer sides of the double-headed worm gear. A rotating shaft is fixedly passed through the axis of each of the two worm wheels and is vertically rotatably mounted inside the fixed box. Two clamping plates are fixedly mounted on the surface of each of the two rotating shafts and are movable through the outside of the fixed box. A rotating shaft is rotatably mounted on the inner top of the fixed box. The rotating shaft is connected to the double-headed worm gear through a bevel gear set. A knob for driving the rotating shaft to rotate is rotatably mounted on the top of the fixed box.

[0012] Preferably, a bracket is fixedly installed on the side of the fixing box away from the loading arm body, and the bracket is hinged to the top of the fixing cylinder.

[0013] Preferably, each of the clamps has multiple rubber strips fixedly installed on the side near the loading arm body.

[0014] Preferably, the surface of the fixing box is provided with multiple sliding holes, and the sliding holes are slidably connected to the clamping plate.

[0015] Compared with existing technologies, the advantages of the top-loading loading arm for alcohol and ether chemicals provided by this utility model are as follows:

[0016] 1. By placing the sealing cap over the opening of the loading arm body, the opening of the loading arm body can be sealed to prevent impurities from entering the loading arm body and affecting subsequent use. When the loading arm body needs to be used, pull down the sealing cap until it is completely removed from the opening of the loading arm body, and then flip the sealing cap to remove it from the opening of the loading arm body for use.

[0017] 2. By rotating the knob, the rotating shaft is driven by the bevel gear set, which causes the double-headed worm gear to drive the two worm wheels to rotate in opposite directions. Finally, the two rotating shafts drive each clamp plate to move closer to the loading arm body until it is pressed against the surface of the loading arm body, thus completing the fixing of the fixing box and the loading arm body, which facilitates the installation of the sealing cap.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1 to 3A top-loading loading arm for alcohol ether chemicals, comprising:

[0024] The loading arm body 1; the sealing cap 2 is detachably and airtightly connected to the opening of the loading arm body 1. When the loading arm body 1 is not in use, the sealing cap 2 can be put on the opening of the loading arm body 1 to seal the loading arm body 1, so as to prevent impurities from entering the loading arm body 1 and affecting subsequent use.

[0025] The loading and unloading assembly includes a right-angle rod 3 fixedly mounted on the surface of the sealing cap 2. A fixing cylinder 4 is slidably sleeved at one end of the right-angle rod 3 away from the sealing cap 2. A fixing box 5 is rotatably mounted at the other end of the fixing cylinder 4, and the fixing box 5 is detachably connected to the surface of the loading arm body 1. A spring 6 is connected between the inner top of the fixing cylinder 4 and the end of the right-angle rod 3 away from the sealing cap 2. A bracket 7 is fixedly mounted on the side of the fixing box 5 away from the loading arm body 1. The bracket 7 is rotatably connected to the top of the fixing cylinder 4 through a self-locking pivot. When removing the sealing cap 2, first pull the sealing cap 2 down, which will move the right-angle rod 3 inside the fixing cylinder 4 and stretch the spring 6 until the sealing cap 2 is completely detached from the opening of the loading arm body 1. Then, rotate the sealing cap 2 around the self-locking pivot in the direction away from the loading arm body 1, and use the self-locking pivot to lock the position of the sealing cap 2.

[0026] The mounting assembly is used to fix the mounting box 5 to the surface of the loading arm body 1. The mounting assembly includes a double-headed worm gear 8 rotatably installed in the mounting box 5. Two worm wheels 9 are meshed in opposite directions on the outer side of the double-headed worm gear 8. The shafts of the two worm wheels 9 are fixedly penetrated by a rotating shaft 10, and the rotating shaft 10 is vertically rotatably installed in the mounting box 5. Two clamping plates 11 are fixedly installed on the surface of the two rotating shafts 10. Each clamping plate 11 has multiple rubber strips 15 fixedly installed on the side near the loading arm body 1, which can increase the friction between the clamping plate 11 and the surface of the loading arm body 1, thereby improving the connection between the mounting box 5 and the loading arm body 1.

[0027] Furthermore, the clamping plate 11 extends through the outside of the fixing box 5, and the surface of the fixing box 5 is provided with multiple sliding holes 16, which are slidably connected to the clamping plate 11, providing the clamping plate 11 with rotation space.

[0028] A rotating shaft 12 is rotatably mounted on the top of the fixed box 5. The rotating shaft 12 is connected to the double-headed worm gear 8 through a bevel gear set 13. A knob 14 for driving the rotating shaft 12 to rotate is rotatably mounted on the top of the fixed box 5. By rotating the knob 14, the double-headed worm gear 8 can be controlled to rotate under the transmission of the bevel gear set 13.

[0029] The working principle of this utility model is as follows:

[0030] When in use, first put the sealing cap 2 on the opening of the loading arm body 1, then put the fixing box 5 against the surface of the loading arm body 1, and place the two side clamps 11 on both sides of the loading arm body 1 respectively.

[0031] Subsequently, rotating the knob 14 causes the rotating shaft 12 to be driven by the bevel gear set 13, which in turn causes the double-headed worm 8 to drive the two worm wheels 9 to rotate in opposite directions. Finally, the two rotating shafts 10 drive each clamp 11 to move closer to the loading arm body 1 until it is pressed against the surface of the loading arm body 1, thus completing the fixing of the fixing box 5 and the loading arm body 1, which facilitates the installation of the sealing cap 2.

[0032] When the loading arm body 1 is needed, first pull down the sealing cap 2, which will move the right-angle rod 3 inside the fixed cylinder 4 and stretch the spring 6 until the sealing cap 2 is completely separated from the opening of the loading arm body 1. Then, rotate the sealing cap 2 around the self-locking shaft in the direction away from the loading arm body 1 to lock the position of the sealing cap 2.

[0033] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
