[0002] At present, most autoclave equipment on the market cannot be equipped with weighing sensors or equipped with weighing sensors, resulting in the inability to add quantitative materials during the equipment feeding process, and the weighing sensor has no lifting and leveling device during the installation process, resulting in the weighing sensor being installed tilted, making it difficult to weigh reliably, and easily damaged when overloaded, resulting in large economic losses. At present, there is no relatively mature related device in the field of harmless treatment equipment. Based on this opportunity, this paper proposes a new type of weighing sensor lifting device for autoclave equipment.

[0020] The utility model is further described below in conjunction with the accompanying drawings: Example

[0021] As attached Figures 1 to 4As shown, the utility model provides a heavy-duty autoclave equipment weighing sensor lifting device, characterized in that the device comprises a weighing fixed tile 1, a weighing sensor 2, a locking nut 3, an upper mounting plate 4, a screw rod 5, a disc spring 6, a lower mounting plate 7, a fixing seat 8, a proximity switch 9, an adjusting nut 10, a spring retaining ring 11 and a through hole 12; a through hole 12 is respectively arranged at the four corners of the upper end of the lower mounting plate 7, four screw rods 5 are respectively extended into the through holes 12 at corresponding positions and are fixed to the lower mounting plate 7 through the spring retaining ring 11, a plurality of spring retaining rings 11 are sleeved on the lower end of the screw rod 5 boss, the adjusting nut 10 is threadedly connected with the screw rod 5, the through hole on the upper mounting plate 4 passes through the four screw rods 5 and is arranged at the upper end of the adjusting nut 10, a locking nut 3 is fixed to the screw rod 5 at the upper end of the upper mounting plate 4, the weighing sensor 2 is fixed on the upper mounting plate 4, and the weighing fixed tile 1 is fixed to the upper end of the weighing sensor 2.

[0022] Furthermore, a fixing seat 8 is fixedly connected to the side of the lower mounting plate 7, and a proximity switch 9 passes through a through hole at the upper end of the fixing seat 8 and is fixed on the fixing seat 8 via a nut. The detection port of the proximity switch 9 faces the screw 5. When the screw 5 is overloaded, the lower end of the screw 5 extends out of the lower mounting plate 7, so that the screw 5 is close to the proximity switch 9, and the proximity switch 9 receives a signal. At this time, the combined elastic force of the multiple disc springs 6 on the four screws 5 is less than the maximum load-bearing gravity of the weighing sensor 2, thereby avoiding damage to the sensor caused by overloading of the weighing sensor 2, and is used to protect the weighing sensor 2. It is safe and reliable to use.

[0023] Furthermore, the number of proximity switches 9 can be 2-4, and their installation positions are respectively opposite to one screw rod 5. The number of proximity switches 9 installed can be set according to usage requirements.

[0024] Furthermore, the bottom of the screw 5 extends to the position where the proximity switch 9 detects a signal, which is the detection stroke. At this time, the elastic force of the four spring collars 11 connected in series is 0.85-0.95 times the maximum load-bearing gravity of the weighing sensor 2. The limit stroke of the spring collar 11 is greater than the detection stroke, ensuring that the spring collar 11 has sufficient safety in use.

[0025] Furthermore, the height of the adjusting nut 10 on the screw rod 5 is adjusted so that the weighing sensor 2 is installed on a horizontal plane. The mounting surface of the weighing sensor 2 is adjusted using the adjusting nut 10, and the screw rod 5 is locked using the locking nut 3 to achieve the purpose of horizontal installation. It is easy to use and reliable to install.

[0026] The utility model utilizes the height adjustment nuts 10 on the four screw rods 5 to adjust the level of the upper mounting plate 4 so that the weighing sensor 2 can be installed horizontally. The position of the weighing sensor 2 is easy to adjust. The locking nut 3 is used to press the upper mounting plate 4 against the adjusting nut 10 to prevent loosening and improve the reliability of use.

[0027] When the weighing sensor 2 is weighing without overweight, the bottom of the screw 5 extends out. At this time, the extension of the screw 5 does not exceed the position of the proximity switch 9, and the proximity switch 9 does not detect a signal, so the weighing can be carried out effectively. If the weighing sensor 2 is overweight, the bottom of the screw 5 extends to the position where the proximity switch 9 detects a signal. This is the detection stroke. The proximity switch 9 signal is used for overload warning. The structure is simple, safe and reliable to use, and the cost is low. At this time, the elastic force of the four spring collars 11 connected in series is 0.85-0.95 times the maximum load-bearing gravity of the weighing sensor 2. The limit stroke of the spring collar 11 is greater than the detection stroke, which ensures that the spring collar 11 has sufficient safety in use, thereby avoiding damage to the sensor caused by overloading of the weighing sensor 2. It is used to protect the weighing sensor 2, which is safe and reliable to use, and greatly improves the problem of preventing overload damage to the weighing sensor 2.

[0028] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
