Description

Technical Field

[0001] This utility model relates to the field of weighing technology for belt conveyors, specifically a special weighing device for wheel-rail suspended belt conveyors. Background Technology

[0002] Belt conveyors are one of the most important bulk material transport equipment in my country, enabling continuous material transport. Traditional belt conveyors use idlers to support the conveyor belt for transport. However, there are indentation resistance between the conveyor belt and the idlers, rotational resistance of the idlers, and compressive resistance between the conveyor belt and the material, resulting in significant transport resistance along the conveyor line. Furthermore, as the conveying distance increases, the transport resistance also increases, leading to higher overall energy consumption and greater demands on the strength of the conveyor belt.

[0003] To address the above issues and improve conveying efficiency while reducing energy consumption, a wheel-rail suspended belt conveyor has emerged. While wheel-rail suspended belt conveyors require weighing capabilities, traditional belt weighing structures and devices are not suitable for this new type of conveyor, and some belt scales have relatively high weighing costs. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a special weighing device for wheel-rail suspended belt conveyors, which can meet the weighing requirements of wheel-rail suspended belt conveyors, with relatively low cost, high accuracy, and convenient loading and unloading.

[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 5 As shown, a weighing device specifically designed for wheel-rail suspended belt conveyors includes four legs 1, connected to adjacent legs 1 by a support frame 3. The support frame 3 has round holes at both ends for easy bolt connection to the legs 1. The support frame 3 is equipped with an upper support plate, and a connecting gasket 8 is mounted on the top of the upper support plate. A weighing sensor 5 is mounted on the connecting gasket 8, and a weighing rail 2 is mounted on top of the weighing sensor 5. A first wheel guide rail is mounted on top of the weighing rail 2. When the wheel-rail trolley of the wheel-rail suspended belt conveyor runs along the first wheel guide rail, the weighing sensor 5 on the support frame 3 performs real-time weighing of the wheel-rail trolley, its belt, and the materials, meeting the weighing requirements of the wheel-rail suspended belt conveyor. This method is low-cost, convenient, and fast.

[0029] The top of the load cell 5 is equipped with an upper pad 41. The flatness of the lower surface of the upper pad 41 is ensured by machining in the workshop. The upper pad 41 is welded to the weighing rail 2. The bottom of the load cell 5 is equipped with a lower pad 42. The load cell 5, the upper pad 41, the load cell 5, the lower pad 42, and the connecting washer 8 are fixed by bolts in sequence, which facilitates installation, removal and replacement. At the bolt connection between the support frame 3 and the support leg 1, the support leg 1 is drilled with elongated holes and the support frame 3 is drilled with round holes, which facilitates the leveling of the upper surface of the four lower pads after on-site installation, thereby improving the weighing accuracy of the load cell.

[0030] The weighing track 2 includes a first left guide rail 21 and a first right guide rail 22; the support frame 3 includes a left support frame and a right support frame; the upper support plate includes two first upper support plates, two second upper support plates, two third upper support plates, and two fourth upper support plates; the weighing sensor 5 includes a first left weighing sensor, a second left weighing sensor, a first right weighing sensor, and a second right weighing sensor; the first wheel guide rail includes a first left wheel guide rail and a first right wheel guide rail; the two first upper support plates and the two second upper support plates are respectively mounted on the left support frame; the two third upper support plates and the two fourth upper support plates are respectively mounted on the right support frame; the first left... Weighing sensors are installed on the top of the two first upper support plates, and the second weighing sensor is installed on the top of the two second upper support plates. The first left guide rail 21 is installed on the top of the first and second upper support plates, and the first left wheel guide rail is installed on the top of the first left guide rail 21. The first right weighing sensor is installed on the top of the two third upper support plates, and the second right weighing sensor is installed on the top of the two fourth upper support plates. The first right guide rail 22 is installed on the top of the third and fourth upper support plates, and the first right wheel guide rail is installed on the top of the first right guide rail 22. The wheels of the wheel-rail trolley can roll along the first left wheel guide rail and the first right wheel guide rail.

[0031] The first and second weighing sensors are symmetrically arranged, one on the left and one on the right, and the second weighing sensor is symmetrically arranged with the second weighing sensor on the right. When the wheel-rail trolley is running normally, it will simultaneously pass over all four weighing sensors. To accurately select the appropriate weighing sensor, calculations are needed based on the following three scenarios: the readings of the four weighing sensors when the wheel-rail trolley is directly over the first and second weighing sensors; the readings of the four weighing sensors when the wheel-rail trolley is directly over the second and second weighing sensors; and the readings of the four weighing sensors when there is no wheel-rail trolley. After testing the maximum load capacity, the weighing range of the weighing sensors can be obtained, allowing the selection of a weighing sensor with a specific range. During subsequent operation, the weight of the wheel-rail trolley can be determined simply by adding the readings of the four weighing sensors.

[0032] A return guide intermediate frame 7 is installed below the support frame 3, and the return guide intermediate frame 7 is connected to the support leg 1. The weighing rail 2, support frame 3, and return guide intermediate frame 7 are connected and fixed by one support leg 1, and the support frame 3, load-bearing guide rail 6, and return guide intermediate frame 7 are connected and fixed by one support leg 1. The weighing rail 2, support frame 3, load-bearing guide rail 6, and return guide intermediate frame 7 are all bolted to the support leg 1, which facilitates loading, unloading, and transportation.

[0033] The upper support plate and the return guide rail intermediate frame 7 are both equipped with reinforcing ribs. The top of the reinforcing ribs of the return guide rail intermediate frame 7 is equipped with a second wheel guide rail, and the wheels of the wheel-rail trolley can roll along the second wheel guide rail.

[0034] The upper support plate is a right-angled trapezoidal plate, and the reinforcing rib is an isosceles trapezoidal plate. The long base of the right-angled trapezoidal plate is connected to the support frame 3, and the reinforcing rib is used to support the angle steel.

[0035] A load-bearing guide rail 6 is respectively provided at one end of the first left guide rail 21 and the first right guide rail 22. Gaps are left at the junctions of the first left guide rail 21 and the load-bearing guide rail 6, and at the junctions of the first right guide rail 22 and the load-bearing guide rail 6, so that the weighing sensor 5 only weighs the first left guide rail 21 and the first right guide rail 22. The wheel-rail trolley runs along the first wheel guide rail onto the load-bearing guide rail 6.

[0036] In another embodiment of this application:

[0037] The weighing rail 2, the load-bearing guide rail 6, and the return guide rail intermediate frame 7 are mainly welded from round steel. Their dimensions are determined by the wheel diameter of the wheel-rail trolley. The materials are widely available and easy to manufacture. Here, the round steel is connected to the angle steel, which serves as the load-bearing component for the round steel.
