Abstract
Description
Technical Field
[0001] This utility model relates to the field of weighing technology for circular tube belt conveyors, specifically a weighing intermediate frame for wheel-rail circular tube belt conveyors. Background Technology
[0002] Belt conveyors are one of the most important material handling equipment in my country, enabling continuous material transport. Traditional belt conveyors use idlers to support the conveyor belt. This method suffers from significant transport resistance due to the indentation resistance between the belt and idlers, the rotational resistance of the idlers themselves, and the compressive resistance between the belt and the material. Over long distances, this further increases energy consumption and the belt's strength. Circular tube belt conveyors, on the other hand, are environmentally friendly, compact, have high conveying capacity, and are adaptable to complex terrain, making them widely used in the belt conveyor field.
[0003] To address the above situation and improve conveying efficiency while saving energy, a wheel-rail circular tube belt conveyor has emerged. This conveyor requires weighing capabilities, but some traditional belt scales are unsuitable for this new type of conveyor, while others are too expensive. Therefore, there is an urgent need to design an economical and practical weighing intermediate frame suitable for wheel-rail circular tube belt conveyors. Utility Model Content

[0025] 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, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0027] In one embodiment of this application:
[0028] like Figures 1 to 5As shown, a weighing intermediate frame for a wheel-rail circular tube belt conveyor includes an upper crossbeam assembly 1, a lower crossbeam assembly 2, and two support legs 3. The support legs 3 are U-shaped. The upper crossbeam assembly 1 and the lower crossbeam assembly 2 are connected and fixed by the two support legs 3. The upper crossbeam assembly 1 includes a main crossbeam 7 and a track 4. The main crossbeam 7 is made of channel steel with holes at both ends for easy connection to the connector 10 via bolts. A weighing sensor 6 is installed on the main crossbeam 7, and the track 4 is installed on the weighing sensor 6. The track 4 is determined according to the wheel diameter of the wheel-rail trolley of the wheel-rail circular tube belt conveyor, and a standard track is selected. When the wheel-rail trolley of the wheel-rail circular tube belt conveyor runs along the track 4, the weighing sensor 6 on the main crossbeam 7 weighs the wheel-rail trolley, meeting the weighing requirements of the wheel-rail circular tube belt conveyor, and the cost is relatively low.
[0029] A track pad 5 is provided at the bottom of the track 4. The track pad 5 is placed on the load cell 6, and the track 4 and the load cell 6 are fastened together by the track pad 5.
[0030] The track pad 5 includes a pad 12 and pad blocks 13 for pressing the track 4. The pad blocks 13 include a first pad block and a second pad block, which are respectively disposed on both sides of the track 4. The center of the pad 12 is concave to accommodate the track 4. The depth of the concavity is determined according to the profiles of the load cell 6, the track 4, and the main crossbeam 7 to ensure that the height of the weighing section track is consistent with the height of the ordinary section track. The first and second pad blocks are obliquely cut according to the model of the track 4. The first and second pad blocks press against the left and right sides of the track 4. The first and second pad blocks have openings at both ends. One bolt passes through the first pad block, the pad 12, and the load cell 6 in sequence for fixation, and another bolt passes through the second pad block, the pad 12, and the load cell 6 in sequence for fixation, which facilitates installation, disassembly, and replacement.
[0031] Track 4 includes a left track and a right track; main beam 7 includes a left main beam and a right main beam; track pad 5 includes a first left track pad, a second left track pad, a first right track pad, and a second right track pad; load cell 6 includes a first left load cell, a second left load cell, a first right load cell, and a second right load cell. The first left load cell and the second left load cell are both mounted on the left main beam. The left track is connected to the first left load cell via the first left track pad, and the left track is connected to the second left load cell via the second left track pad. The first right load cell and the second right load cell are both mounted on the right main beam. The right track is connected to the first right load cell via the first right track pad, and the right track is connected to the second right load cell via the second right track pad.
[0032] The first left and first right load cells are symmetrically arranged, as are the second left and second right load cells. When the wheel-rail trolley runs along the left and right tracks, it simultaneously passes over the first left and first right load cells, ensuring uniform force on them and achieving accurate weighing of the trolley. Although the first left, first right, second left, and second right load cells begin weighing the trolley, the left track, and the right track together as soon as the trolley steps onto them, calculating the trolley's true weight requires considering the values displayed by the four load cells when the trolley is over the first left and first right load cells, when the trolley is over the second left and second right load cells, and when the trolley is not present. This method yields a more accurate weight calculation for the wheel-rail trolley.
[0033] The left and right rails are connected by connecting angle steel 8, which allows four weighing sensors to weigh the left and right rails together.
[0034] The bottom of the support leg 3 is provided with a base plate 11.
[0035] The bottom of the main beam 7 is provided with an upper connector, and the support leg 3 is provided with a lower connector. Both the upper and lower connectors are provided with elongated holes. The upper connector is connected to the diagonal brace 9 by bolts, and the lower connector is connected to the diagonal brace 9 by bolts. The diagonal brace 9 is made of angle steel.
[0036] The lower crossbeam assembly 2 includes a lower crossbeam 14 and a lower rail 15. The lower crossbeam 14 includes a lower left crossbeam and a lower right crossbeam, and the lower rail 15 includes a lower left rail and a lower right rail. The lower left crossbeam is fastened to the lower left rail and the lower right crossbeam is fastened to the lower right rail by three lower rail pads 16 respectively. The lower left crossbeam and the lower right crossbeam are connected by a lower connecting angle steel 17. Both the lower left crossbeam and the lower right crossbeam are made of channel steel and have holes at both ends to facilitate connection with the connector 10 by bolts.
[0037] Four connectors 10 are welded to one outrigger 3. The upper two connectors 10 are bolted to the main crossbeam 7, and the lower two connectors 10 are bolted to the lower crossbeam 14.
[0038] In another embodiment of this application:
[0039] Based on the previous embodiment, this embodiment improves the connector 10 and the base plate 11. The connector 10 is made of unequal angle steel. When there is no angle steel that meets the size requirements, the steel plate can be bent into an "L" shape to form the connector 10. The base plate 11 has openings and is fixed to the ground with chemical bolts.
[0040] The above description is merely an embodiment of this utility model. It should be understood that this utility model is not limited to the form disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
