Description

Technical Field

[0001] This utility model relates to the field of heavy material transportation technology, specifically a heavy material rail transportation device in narrow slope and stepped areas. Background Technology

[0002] Due to wear and tear from production use, the ore processing plant needs to periodically replace some worn chain plates. However, individual chain plates are too heavy to be handled manually and must be lifted using overhead cranes and electric hoists. Because the plate feeder is installed in a relatively narrow space, with the ore bin above it and no electric hoists installed on either side, the chain plates were previously transported by dragging them diagonally using the electric hoist at the tail of the feeder. This method presents several safety hazards: uneven force on the electric hoist due to the diagonal pull, increasing the risk of tipping; potential collision risks to operators; and the risk of scratching surrounding equipment. To eliminate these safety hazards and improve the efficiency of transporting chain plates in confined spaces, the transportation method was modified to use a transport trolley for transporting heavy chain plates.

[0003] Existing technology, such as the publication number "CN217534302U", discloses a workshop track material transport trolley, including a track and a trolley body. The bottom of the trolley body is equipped with wheels, and the wheels have guide grooves that cooperate with the track. The trolley body has a rectangular frame structure, and an extension frame is slidably connected inside the trolley body. The upper end of the extension frame is flush with the upper end of the trolley body, and the extension frame is fixed to the trolley body by a detachable positioning pin. The slidable extension frame inside the trolley body increases the length of the trolley body when in use, increasing the amount of material transported at one time, saving time and improving transport efficiency. After use, the extension frame is completely stored inside the trolley body, without occupying additional space, avoiding obstruction of processing operations, thus saving workshop space and making operations more convenient.

[0004] The existing problems with the rail-mounted material transport trolley in this workshop are as follows: the extension frame of the trolley is of fixed length, which cannot flexibly match the actual dimensions of materials of different specifications or models. This may lead to the risk of material instability, shaking, or even slippage during handling due to size mismatch. Furthermore, in narrow or special working environments, it is prone to collisions and equipment damage, thereby reducing handling efficiency and safety and limiting its application scope. Therefore, we propose a heavy material rail transport device for narrow ramps and stepped areas. Utility Model Content

[0005] The purpose of this invention is to solve the problem of lack of size adaptability and to provide a heavy material rail transport device for narrow slopes and stepped areas.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heavy material rail transport device for narrow slopes and stepped areas includes angle iron, with a channel steel fixedly installed on the top of the angle iron. A transport adjustment device is provided on the top of the channel steel. The transport adjustment device includes six casters, which are arranged in pairs. Each pair of casters is located on the top of the channel steel. A front plate, a middle plate, and a rear plate are fixedly installed on the top of each pair of casters. A rear placement plate is fixedly installed on the top of the rear plate, and a front placement plate is fixedly installed on the top of the front plate. Two slide rails are fixedly installed on the side walls of the rear placement plate, and two slide rods are fixedly installed on the side walls of the front placement plate. A rotating rod is rotatably installed through the side wall of the middle plate. A gear is fixedly installed on the outer wall of the rotating rod near the slide rod, and a handle is fixedly installed on the end of the rotating rod away from the gear.

[0008] Preferably, the side walls of the two slide rods are respectively provided with slide grooves, and a number of tooth blocks are fixedly installed on the inner walls of the slide grooves of the two slide rods.

[0009] Preferably, the two slide rods are slidably mounted on the inner walls of the two slide rails, and the center plate is fixedly mounted on the inner walls of the two slide rails opposite each other.

[0010] Preferably, the gear on the rotating rod meshes with several tooth blocks on the sliding rod.

[0011] Preferably, the top surfaces of the rear placement plate, the front placement plate, and the center plate are at the same height.

[0012] Preferably, a traction ring is welded to the front end of the front plate, and the traction rope is connected through the ring. The traction ring is designed to have a tensile strength greater than or equal to five tons.

[0013] Preferably, the length of the chute and the number of toothed blocks can be set using the existing maximum specification chain plate.

[0014] By employing the above technical solution, this utility model provides a heavy material rail transport device for narrow slopes and stepped areas. Its beneficial effects are: by rotating the throttle, this utility model drives gear blocks and other structures to slide and converge the front placement plate towards the rear placement plate, thereby reducing the overall load-bearing length of the transport trolley. This adjustment ensures that the chain plate is placed stably and safely on the transport trolley, avoiding problems such as shaking, slippage, or instability during handling due to size mismatch.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] A heavy material rail transport device for narrow slopes and stepped areas, such as Figures 1-4 As shown, the device includes an angle iron 1, a channel steel 2 fixedly mounted on the top of the angle iron 1, a transport adjustment device 3 on the top of the channel steel 2, and six casters 31. The six casters 31 are arranged in groups of two, and each group of casters 31 is located on the top of the channel steel 2. A front plate 3201, a middle plate 3202, and a rear plate 3203 are fixedly mounted on the top of each group of casters 31. A rear placement plate 33 is fixedly mounted on the top of the rear plate 3203, a front placement plate 34 is fixedly mounted on the top of the front plate 3201, two slide rails 35 are fixedly mounted on the side wall of the rear placement plate 33, two slide rods 360 are fixedly mounted on the side wall of the front placement plate 34, a rotating rod 37 is rotatably mounted through the side wall of the middle plate 3202, a gear 38 is fixedly mounted on the outer wall of the rotating rod 37 near the slide rod 360, and a handle 39 is fixedly mounted on the end of the rotating rod 37 away from the gear 38.

[0024] The side walls of the two slide bars 360 are respectively provided with slide grooves 361, and a number of tooth blocks 362 are fixedly installed on the inner walls of the slide grooves 361 of the two slide bars 360.

[0025] Two sliding rods 360 are slidably installed on the inner walls of two slide rails 35 respectively, and the center plate 3202 is fixedly installed on the opposite inner walls of the two slide rails 35.

[0026] The gear 38 on the rotating rod 37 meshes with several tooth blocks 362 on the sliding rod 360.

[0027] The top surfaces of the rear placement plate 33, the front placement plate 34, and the middle plate 3202 are at the same height.

[0028] The front end of the front plate 3201 is welded with a traction ring, through which the traction rope is connected. The traction ring is designed to have a tensile strength greater than or equal to five tons.

[0029] The length of the chute 361 and the number of tooth blocks 362 can be set using the existing maximum specification chain plate.

[0030] In use, the heavy material rail transport device of this utility model for narrow slopes and stepped areas involves placing the transport trolley on top of the channel steel 2. After the chain plate to be replaced is hoisted to the top of the transport trolley using an electric hoist, and when the size of the transport trolley needs to be adjusted according to the specified chain plate, the handle 39 is turned counterclockwise. The handle 39 drives the rotating rod 37 to rotate, which in turn drives the gear 38 to rotate. The gear 38 meshes with the toothed block 362 on the slide rod 360, causing the gear 38 to drive the toothed block 362 on the slide rod 360 to move backward, thus positioning the plate 33. The sliding mechanism, with slide bar 360, causes the front placement plate 34 to slide towards the rear placement plate 33. The front placement plate 34 then causes the front plate 3201 to converge towards the center. After adjusting to the corresponding dimensions according to the top-mounted chain plate, the electric hoist is driven to place the chain plate on top of the front placement plate 34 and the rear placement plate 33. The transport trolley is then moved towards the front end of the track using a traction rope. Rotating the throttle 39 drives the gear 38 teeth and 362, causing the front placement plate 34 to slide and converge towards the rear placement plate 33, thus reducing the overall load-bearing length of the transport trolley. This adjustment ensures that the chain plate is placed stably and safely on the transport trolley, avoiding problems such as shaking, slippage, or instability during transport due to size mismatch.
