Description

Technical Field

[0001] This utility model relates to the field of material transport vehicle technology, and in particular to a dual-purpose (road and rail) material transport vehicle. Background Technology

[0002] Rail-mounted material handling trolleys are devices used to transport materials or goods on rails. They are widely used in factories, warehouses, mines, construction sites, and railway transportation systems. They can move efficiently and safely on pre-set tracks to achieve rapid material transfer.

[0003] Currently, when a dual-purpose road-rail material transport trolley is running on the track, it mainly relies on the friction between the braking structure and the rail wheels, and then uses the friction between the rail wheels and the track to bring the trolley to a stop. However, since the friction between the rail wheels and the track comes only from the pressure generated by the weight of the trolley itself, the strength of this friction is limited. In practical applications, the trolley often shifts after the braking operation is completed, which has an adverse impact on operational safety and efficiency. Summary of the Invention

[0004] This utility model embodiment relates to a dual-purpose road-rail material transport trolley, which uses two brake levers to simultaneously brake and position the two track wheels, ensuring the braking effect of the material transport trolley on the track to a certain extent. At the same time, by moving the clamping plate inward to clamp the track from both sides, the braking effect of the material transport trolley is further improved by clamping the track, thereby further ensuring the stability of the material transport trolley when loading and unloading materials. Moreover, this material transport trolley can not only transport materials on land, but also travel along the track path to transport materials, improving the adaptability of the material transport trolley.

[0005] In a first aspect, this utility model provides a dual-purpose (road and rail) material transport trolley, specifically comprising: a car body frame; support frames fixedly installed on both sides of the bottom of the car body frame; track wheels rotatably mounted on the support frames; a material transport platform fixedly installed on the top of the car body frame; a drive screw rotatably installed at the center of the top of the car body frame; a force-bearing plate slidably installed at the top of the support frames; force-bearing blocks fixedly installed on the front and rear sides of the top of the force-bearing plate; and brake levers fixedly installed at the front and rear ends of the bottom of the force-bearing plate; the brake... The bottom end of the rod is positioned above the track-moving wheel; a push block is mounted on the drive screw via threads; a transmission block is also mounted on the drive screw via threads; transmission plates are fixedly mounted on the left and right sides of the transmission block; a transmission column is fixedly mounted on the bottom outer end of the transmission plate; a guide rod is fixedly mounted inside the vehicle frame; a clamping slide plate is slidably mounted on the guide rod; a clamping disc is fixedly mounted on the inner bottom end of the clamping slide plate; a driven plate is fixedly mounted on the top of the clamping slide plate; a driven groove is formed on the top of the driven plate.

[0006] Furthermore, the vehicle frame has a rectangular structure; land-based wheels are rotatably mounted at the four bottom corners of the vehicle frame; a vehicle push handle is fixedly mounted at the top rear end of the vehicle frame; the vehicle push handle has a U-shaped structure.

[0007] Furthermore, the rear end of the force-bearing block has an inclined structure; one end of the spring A is embedded in the bottom of the force-bearing plate; the other end of the spring A is embedded in the inside of the support frame.

[0008] Furthermore, when the push block moves forward, it pushes against the inclined surface of the force-bearing block.

[0009] Furthermore, the transmission block is located between the two push blocks.

[0010] Furthermore, a spring B is embedded between the clamping slide and the interior of the vehicle frame.

[0011] Furthermore, the driven groove has an inclined structure; the transmission column is also slidably installed inside the driven groove.

[0012] This utility model provides a dual-purpose (road and rail) material transport trolley, which has the following beneficial effects:

[0013] 1. When braking is required, simply rotate the drive screw to control the two brake levers to descend through the action of the corresponding structure, so that the two brake levers simultaneously brake and position the two track wheels, which to a certain extent ensures the braking effect of the material transport trolley on the track, making it convenient for workers to use the material transport trolley to load and unload materials after braking.

[0014] 2. When the drive screw rotates, the corresponding structure will also control the clamping slide and clamping plate to move inward, so that they clamp the track from the left and right sides by moving inward, thereby further improving the braking effect of the material transport trolley by clamping the track, further ensuring the stability of the material transport trolley when loading and unloading, and making it less likely to have insufficient braking friction.

[0015] 3. This material transport trolley is equipped with both land-based wheels and track-based wheels, with the track-based wheels positioned higher than the land-based wheels. This allows the trolley to transport materials not only on land but also along track paths, improving its adaptability. Attached Figure Description

[0026] 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. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please refer to Figures 1 to 5 Example 1:

[0028] This utility model proposes a dual-purpose (road and rail) material transport trolley, comprising: a car frame 1, with support frames 4 fixedly installed on both sides of the bottom of the car frame 1; track wheels 5 rotatably installed on the support frames 4; a material transport platform 6 fixedly installed on the top of the car frame 1; a drive screw 7 rotatably installed at the center of the top of the car frame 1; a force-bearing plate 8 slidably installed at the top of the support frame 4; force-bearing blocks 9 fixedly installed on the front and rear sides of the top of the force-bearing plate 8; brake rods 11 fixedly installed at the front and rear ends of the bottom of the force-bearing plate 8; the bottom end of the brake rod 11 is above the track wheels 5; and a push block 12 is installed on the drive screw 7 via threads. A transmission block 13 is also installed on the drive screw 7 via threads; transmission plates 14 are fixedly installed on the left and right sides of the transmission block 13; a transmission column 15 is fixedly installed at the bottom outer end of the transmission plate 14; a guide rod 16 is fixedly installed inside the car frame 1; a clamping slide plate 17 is slidably installed on the guide rod 16; a clamping disc 21 is fixedly installed at the bottom inner side of the clamping slide plate 17; a driven plate 19 is fixedly installed on the top of the clamping slide plate 17; a driven groove 20 is opened on the top of the driven plate 19. By pushing the car push handle 3, the car frame 1 moves along the track under the action of the track driving wheels 5, and the material is transported by track.

[0029] In Example 2, based on Example 1, the vehicle frame 1 has a rectangular structure; land wheels 2 are rotatably installed at the four corners of the bottom of the vehicle frame 1; a vehicle push handle 3 is fixedly installed at the top rear end of the vehicle frame 1; the vehicle push handle 3 has a U-shaped structure; the rear end of the force block 9 has an inclined structure; one end of a spring A10 is embedded in the bottom of the force plate 8; the other end of the spring A10 is embedded in the support frame 4, and by rotating, it moves the push block 12 and the transmission block 13 forward. During the movement, the push block 12 pushes the inclined surface of the force block 9, causing it to be subjected to force and lower the force plate 8 and the brake lever 11. The two brake levers 11 descend simultaneously to facilitate contact between the two track wheels 5, thereby stopping the track wheels 5 and completing the first braking action of this material transport trolley.

[0030] In Example 3, based on Example 2, when the push block 12 moves forward, it pushes the inclined surface of the force-bearing block 9; the transmission block 13 is located between the two push blocks 12; the clamping slide plate 17 and the interior of the car frame 1 are both fitted with a spring B18; the driven groove 20 has an inclined structure; the transmission column 15 is also slidably installed inside the driven groove 20. When the transmission block 13 moves forward, the transmission block 13 will also move forward with the transmission plate 14 and the transmission column 15. During the forward movement, the transmission column 15 uses the inclined structure of the driven groove 20 to convert the forward force into an inward force and provide it to the driven plate 19. The driven plate 19 carries the clamping slide plate 17 and the clamping disc 21, and the clamping disc 21 clamps the track from both sides by inward movement, clamping and positioning the material transport trolley on the track.

[0031] Working principle: In use, firstly, by pushing the vehicle body push handle 3, the vehicle body frame 1 moves along the track under the action of the track moving wheels 5, using the track to transport materials. After transporting to the fixed position, the drive screw 7 is manually rotated, causing it to move forward along with the push block 12 and the transmission block 13. During the movement, the push block 12 pushes against the inclined surface of the force block 9, causing it to lower the force plate 8 and the brake lever 11. The two brake levers 11 descend simultaneously, facilitating contact between the two track moving wheels 5, thus achieving contact between the track moving wheels. The braking action of step 5 completes the first braking action of the material transport trolley. When the transmission block 13 moves forward, it also moves the transmission plate 14 and transmission column 15 forward. During the forward movement of the transmission column 15, the inclined structure of the driven groove 20 converts the forward force into an inward force, which is provided to the driven plate 19. The driven plate 19 carries the clamping slide plate 17 and the clamping disc 21, and the clamping disc 21 clamps the track from both sides by moving inward, clamping and positioning the material transport trolley on the track, further enhancing the stability of the material transport trolley after braking.

[0034] 2. Where there is no conflict, the embodiments of this utility model and the features in the embodiments can be combined with each other to obtain new embodiments.
