Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying equipment and relates to a wheel-rail type scrap steel conveyor. Background Art

[0002] As an indispensable important raw material in the iron and steel industry, scrap steel's unique environmental protection attributes and potential for infinite recycling make it a key element in building a "green iron and steel" industry, promoting a low-carbon economy, and building a resource-saving and environment-friendly society. The reuse of scrap steel can not only significantly reduce energy consumption and environmental pollution but also effectively reduce dependence on primary ore resources and promote the maintenance of ecological balance.

[0003] Currently, iron and steel enterprises generally use trucks to transport scrap steel to the production site and then use equipment such as short-distance and low-capacity chain plate conveyors to send the scrap steel to the final use point. However, with the increasing global emphasis on carbon emission control and carbon neutrality goals, the usage ratio of scrap steel is expected to continue to rise. This will lead to a sharp increase in the usage frequency of traditional truck transportation methods, thereby increasing logistics costs and transportation loads and having a negative impact on the economic benefits and environmental performance of enterprises.

[0004] In addition, the sharp edges and high-strength wear characteristics of scrap steel materials pose a severe challenge to traditional belt conveyors. Ordinary conveyor belts are extremely vulnerable to scratching or tearing when carrying scrap steel, which not only reduces the conveying efficiency but also increases the maintenance cost and may even cause production interruptions, affecting the stable operation of the entire production line.

[0005] Therefore, developing a new type of scrap steel conveying system aimed at overcoming the limitations of the existing technology, improving the safety, reliability, and economy of scrap steel conveying has become an urgent technical issue in the current iron and steel industry. An ideal solution should be able to adapt to the special physical properties of scrap steel and at the same time meet the requirements of large-scale and long-distance conveying to promote the green transformation and sustainable development of iron and steel production. Summary of the Utility Model

[0006] In view of this, the purpose of the utility model is to provide a wheel-rail type scrap steel conveyor, which has the characteristics of being suitable for long-distance conveying and easy to reverse, a metal tray with a wide range of adaptable materials, and low wheel-rail conveying resistance. It can well solve the problem of scrap steel conveying, realize the continuous conveying of scrap steel over a long distance, with a long service life and low energy consumption, and optimize the existing transportation mode of scrap steel in iron and steel enterprises.

[0007] To achieve the above object, the present utility model provides the following technical solutions: a wheel-rail type scrap conveyor, comprising a conveyor drum, a tail drum, and a conveyor belt that surrounds the conveyor drum and the tail drum and is connected end to end to form a closed loop. A tail tensioning device is also connected to the end of the tail drum, and the tensioning device can also be arranged at other positions according to needs. Paired parallel running tracks are arranged on both sides of the conveyor belt. A plurality of carrier trucks are installed along the length direction of the conveyor belt. The carrier truck includes a tray, wheels, and a carrier truck shaft arranged between the wheels. The wheels are rotatably arranged on the running tracks on both sides; the tray of the carrier truck is used to carry and transport materials. The tray is arranged above the conveyor belt, and the conveyor belt drives it to make a reciprocating rotary motion through a driving drum, thereby driving the carrier truck installed on the conveyor belt and the materials carried by it to move along the running tracks.

[0008] Optionally, the conveyor belt is a flat belt. A plurality of hanging ears are arranged at intervals along the length direction of the conveyor belt. The carrier truck shaft of the carrier truck passes through the hanging ears and is installed on the conveyor belt through the hanging ears of the conveyor belt.

[0009] Optionally, the conveyor belt is a conveyor belt with corrugated edges on both sides. A plurality of small holes are arranged on the corrugated edges on both sides.

[0010] Optionally, the carrier truck shaft of the carrier truck is integrally vulcanized with the conveyor belt, and the carrier truck is installed on the conveyor belt by vulcanization.

[0011] Optionally, the tray of the carrier truck is of a non-uniform cross-section structure type, and the trays of two adjacent carrier trucks overlap front and back to prevent the bulk materials carried from spilling through the gaps between the trays.

[0012] Optionally, the wheel shaft of the carrier truck is of a half-shaft structure or a through-shaft structure.

[0013] Optionally, the wheels of the carrier truck are provided with flanges to prevent the wheels from derailing.

[0014] Optionally, the running track includes an upper track and a lower track. Both the upper track and the lower track each include a straight track and curved tracks located at both ends of the straight track.

[0015] Optionally, there is an overlapping section between the upper track and the lower track at the commutation position. The wheels of the carrier truck enter the overlapping section during commutation. After the wheels of the carrier truck enter the overlapping section, they run on both the upper track section and the lower track section, thereby achieving smooth commutation.

[0033] Specific Embodiment 1

[0034] Please refer to Figures 1 - 6, the rail-wheel type scrap conveyor provided by the utility model comprises a driving drum 1, a tail drum 12, a conveyor belt 2 that forms a closed loop by surrounding the driving drum 1 and the tail drum and connecting head to tail, a trolley 3, walking tracks 4 that are arranged in pairs and parallel on both sides of the conveyor belt 2, and a tail tensioning device 13 connected to the tail drum 12. A plurality of trolleys 3 are installed on the conveyor belt 2 along the length direction. The trolley 3 is provided with a tray 5 and wheels 6. The tray of the trolley is used to carry and convey materials 7. The conveyor belt 2 does not directly carry the materials 7 but is driven by the driving drum 1 to make a reciprocating rotary motion, so as to drive the trolleys 3 installed on the conveyor belt 2 and the materials 7 they carry to move along the walking tracks 4.

[0035] Preferably, in this embodiment, the conveyor belt 2 is a flat belt. A plurality of lugs 8 are arranged at intervals along the length direction of the conveyor belt 2. The wheel shaft 9 passes through the lugs 8, and the trolley 3 is installed on the conveyor belt 2 through the conveyor belt lugs 8.

[0036] Preferably, the trolley tray 5 in this embodiment is of a non-uniform cross-section structure type, so that the trolley trays 5 can be overlapped front and back to prevent the bulk materials 7 carried from falling through the gaps between the trays 5 and the trays 5.

[0037] Preferably, the wheel shaft 9 in this embodiment is of a through-shaft structure.

[0038] Preferably, the wheels 6 in this embodiment are provided with flanges to prevent the wheels 6 from derailing.

[0039] Preferably, the walking tracks 4 in this embodiment comprise an upper track 10 and a lower track 11. The upper track 10 comprises a straight track 101 and curved tracks 102 and 103 at both ends of the straight track 101. The lower track 11 comprises a straight track 111 and curved tracks 112 and 113 at both ends of the straight track 111.

[0040] Preferably, there is an overlapping section between the upper track 10 and the lower track 11 at the commutation position in this embodiment. The wheels 6 of the trolley 3 enter the overlapping section during commutation. After the wheels of the trolley enter the overlapping section, they travel on both the upper track section 10 and the lower track section 11, so as to achieve smooth commutation.

[0041] The specific working process of this embodiment is as follows: The driving roller 1 rotates counterclockwise, driving the conveyor belt 2 to make a reciprocating rotary motion. A plurality of trolleys 3 installed on the conveyor belt 2 move together with the conveyor belt 3. The trolleys 3 move on the running track by relying on the wheels 6. Due to the wheel-rail contact mode, compared with the prior art, the running resistance can be greatly reduced, so that the conveying distance of the conveyor can be made longer than that of the existing chain plate conveyor. When the trolley 3 runs from the upper straight track 101 to the upper bending track 102 on the side of the driving roller, the gap between the front and rear trolleys 3 gradually changes. As the attitude angle of the tray 5 continuously changes when running on the bending section 102 on the driving side of the upper track, the material carried in the tray 3 is finally unloaded under the action of gravity. The trolley 3 gradually moves from the bending section 102 on the driving roller side of the upper track to the lower straight section 111 and then enters the upper straight track 101 through the bending section 113 on the tail roller side of the lower track - the bending section 103 on the tail roller side of the upper track, and so on in a cycle to achieve continuous cyclic conveying.

[0042] To better enable the trolley 3 to follow the conveyor belt 2 to complete the commutation work along the established track, there is an overlapping area between the bending section 102 on the driving roller side of the upper track and the bending section 112 on the driving roller side of the lower track in this embodiment, and the bending section 103 on the tail roller side of the upper track and the bending section 113 on the tail roller side of the lower track. When the wheel 6 of the trolley 3 enters the bending section 102 on the driving roller side of the upper track, the wheel 6 of the trolley 3 also travels on the bending section 112 on the driving side of the lower track at the same time. Similarly, when the wheel 6 of the trolley 3 enters the bending section 113 on the tail roller side of the lower track from the lower straight section 111, the wheel 6 of the trolley 3 also travels on the bending section 103 on the tail roller side of the upper track at the same time.
