Description

Technical Field

[0001] This utility model relates to the field of industrial metering equipment technology, and in particular to a weighing internal support device for a reactor lug-type support. Background Technology

[0002] In industries such as petroleum, chemical, food, and pharmaceutical, vertical storage tanks widely use lug supports for support, with weighing modules installed below the supports to monitor the weight of the materials inside the tank in real time. To ensure the accuracy and reliability of the weighing, these weighing modules need to be calibrated regularly.

[0003] Currently, the most direct calibration method is to apply standard weights. However, lug supports are typically saddle-shaped or lug-shaped structures, lacking stable, flat load-bearing surfaces at the top and inside, making it impossible to directly and safely place large amounts of standard weights. While indirect calibration devices such as hydraulic loading exist, these devices are usually expensive, have complex operating procedures, and poor portability, making them unsuitable for routine, periodic on-site calibration work. Utility Model Content

[0004] The purpose of this invention is to solve the above problems and provide a weighing internal support device for a reactor lug support. It has a simple structure, low cost, is easy to carry and install, and can effectively apply a standard calibration load on the lug support.

[0005] The technical solution adopted by this utility model is: A weighing internal support device for a reactor lug support is characterized in that the lug support of the reactor has two side walls and a bottom. The bottom of the lug support is fixed to a weighing module. The internal support device includes a bolt, the length of which is slightly less than the distance between the inner sides of the two lug arms of the lug support. A first nut is screwed onto the tail end of the bolt. At least two support arms are provided on the bolt. The front end of each support arm is engaged with the bolt by a second nut. A support column is provided below the support arm. When the first nut is screwed outward, so that the head and tail of the bolt are lifted and fixed to the inner sides of the two lug arms of the lug support, the support column and the bottom of the lug support form a support, so that the support arm is in a horizontal state to support the calibration weight.

[0006] Furthermore, the rear ends of the at least two support arms are connected and fixed by a connecting rod.

[0007] Furthermore, the support pole is located within the front 1 / 3 position of the support arm.

[0008] Furthermore, the diameter of the bolt is greater than or equal to M16.

[0009] Furthermore, the length of the bolt is less than 1 / 3 to 1 / 2 the thickness of the first nut than the distance between the inner sides of the two arms of the lug support.

[0010] The beneficial effects of this utility model are: (1) It has a simple structure, is easy to manufacture, and is easy to carry and use; (2) The support is firm and the load-bearing capacity is large. Different internal support devices are designed according to the capacity and size of different reactors to meet the placement of the weights. (3) The structure of the reactor is not changed and it is installed as needed. Attached Figure Description

[0013] The following detailed description, in conjunction with the accompanying drawings, describes the specific implementation of a reaction vessel lug-type support weighing internal brace device according to this utility model.

[0014] See appendix Figure 1 , 2 The bottom 21 of the reactor 1 is equipped with multiple lug supports 2, with the bottom 21 below the supports and two side walls 22 above. The bottom 21 of each support is fixed to a weighing module 3 for dynamic weighing of the reactor 1. The weighing module 3 is a ground weighing device in the prior art, such as a floor scale.

[0015] The internal support device 4 includes a bolt 5. The length of the bolt 5 is slightly less than the distance between the inner sides of the two arms of the ear-type support 2. A first nut 6 is screwed onto the tail end of the bolt 5. The first nut 6 and the head of the bolt 5 are used to control the force-bearing position of the two arms of the ear-type support 2. The length of the bolt 5 is 1 / 3 to 1 / 2 the thickness of the first nut 6 less than the distance between the inner sides of the two arms of the ear-type support 2. When the first nut 6 is screwed outward, it tightly supports the head of the bolt 5 and the first nut 6 within the two arms of the ear-type support 2, forming a strong support with a large bearing force.

[0016] See appendix Figure 3Two support arms 7 are set on the bolt 5. The front end of the support arm 7 is engaged with the bolt 5 by the second nut 8. A support rod 9 is set below the support arm 7. The support rod 9 is located in the front 1 / 3 position of the support arm 7 so that the support rod 9 and the bottom 21 of the ear support 2 can support each other. The bottom 21 of the ear support 2 and the two side walls 22 are a whole. At the same time, it generates positive pressure on the balancing module 3, so that the support rod 9 exerts pressure on the bottom 21 of the ear support 2.

[0017] The rear ends of the two support arms 7 are connected and fixed by connecting rods 10, forming a frame structure with bolts 5 for placing calibration weights on top. The internal support device 4 is also sized according to the size of the reactor 1 and the lug support 2. Three or more support arms 7 can be set, forming multiple horizontal support arms 7 for arranging calibration weights on top. Based on the size of the reactor 1 and the lug support 2, the diameter of bolts 5 is selected to be greater than or equal to M16, and the support arms 7 are also made of materials of corresponding dimensions to ensure that the support arms 7 meet the important load-bearing requirements for the calibration weights.

[0018] During weighing calibration, the two ends of the bolts 5 of the inner support device 4 are positioned inside the two side arms of the ear-type support 2. The first nut 6 is then turned outwards, causing the head and tail of the bolt 5 and the first nut 6 to be lifted and fixed to the inside of the two side arms of the ear-type support 2. This lifting force is then reinforced with a wrench to ensure it can withstand sufficient downward pressure. At this point, because the support rod 9 and the bottom 21 of the ear-type support 2 form a support, the support arm 7 is in a horizontal state and can be used to support the calibration weights.

[0019] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
