Description

Technical Field

[0001] This application relates to the technical field of material transportation, and in particular to a material transport trolley with a braking structure. Background Technology

[0002] Material transport carts are mainly used for short-distance transport of parts and construction materials in tunneling roadways in coal mines and other mining industries. By replacing manual handling, they reduce the labor intensity of workers, shorten the material transport time in the roadway, and thus improve the overall efficiency of tunneling operations. Currently, existing material transport trolleys typically include a vehicle body, wheels mounted at the bottom of the vehicle body, and a push handle fixed to one side of the vehicle body. In use, the operator places the material to be transported inside the vehicle body, and the operator pushes the vehicle body through the push handle, relying on the wheels rolling on the ground to move the material. When existing material transport carts are used in tunneling roadways, the underground geological conditions cause the roadways to have varying slopes, making it difficult for the carts to stop suddenly. This affects the material supply efficiency of the tunneling operation, and the carts are prone to slipping or colliding with the roadway walls if they cannot stop in time. Summary of the Invention

[0003] To facilitate emergency stopping of the material transport trolley, this application provides a material transport trolley with a braking structure.

[0004] This application provides a material transport trolley with a braking structure, which adopts the following technical solution: A material handling trolley with a braking structure includes a trolley body, a rotating assembly, a braking assembly, a pushing assembly, and a locking assembly. The trolley body is horizontally positioned and has an open top. A push rod is fixedly mounted on one side of the trolley body, a support rod is fixedly mounted on the bottom of the trolley body, and a discharge plate is rotatably mounted on one side of the trolley body. The rotating assembly is located on the trolley body and is used to drive the trolley body to move on the ground. The braking assembly is located on the trolley body and is used to stop the rotating assembly. The pushing assembly is located inside the trolley body and is used to push out the material inside the trolley body. The locking assembly is located on the trolley body and is used to lock the discharge plate.

[0005] By adopting the above technical solution, during use, the operator first puts the material to be transferred into the car body with the top opening. The operator then drives the car body to move on the ground of the tunnel by rotating the component. When unloading is required, the operator unlocks the unloading plate by locking the component, making the unloading plate easy to rotate. At the same time, the operator drives the pushing component to work, which pushes the material in the car body out of the car body through the open unloading plate. When the car body needs to stop suddenly, the operator drives the braking component to work, which drives the rotating component to stop working. The support rod provides auxiliary support after the car body stops, making it easy for the material transport trolley to stop suddenly.

[0006] Optionally, two sets of the rotating assembly are provided, and are respectively located on both sides of the vehicle body; the rotating assembly includes a mounting frame, a rotating rod, and a rotating bracket; the mounting frame is fixedly installed at the bottom end of the vehicle body, and the rotating rod is rotatably inserted into the mounting frame; the rotating bracket is fixedly installed on the rotating rod, and a rotating wheel is fixedly sleeved on the rotating bracket.

[0007] By adopting the above technical solution, when in use, the operator pushes the push rod, and the thrust of the vehicle body drives the rotating rod to rotate. The rotating rod drives the rotating wheel to contact the ground and roll through the rotating frame, making the vehicle body easy to move.

[0008] Optionally, the brake assembly is provided in two sets, corresponding one-to-one with the two sets of rotating assemblies; the brake assembly includes a brake part and a drive part; the brake part is located on the mounting frame and is used to drive the rotating frame to stop rotating; the drive part is located on the push rod and is used to drive the brake part to work; the brake part includes a brake disc, a support plate, a first adjusting telescopic rod, and a second adjusting telescopic rod; the brake disc is fixedly mounted on the rotating rod and located on one side of the mounting frame; the support plate is fixedly mounted on one side of the mounting frame, a first mounting plate is fixedly mounted on the support plate, a second mounting plate is fixedly mounted on the support plate, and the second mounting plate is located on one side of the first mounting plate; the first adjusting telescopic rod is horizontally arranged, and its fixed end is fixedly mounted on the first mounting plate, and a first brake pad is fixedly mounted on the movable end of the first adjusting telescopic rod; the second adjusting telescopic rod is horizontally arranged, and its fixed end is fixedly mounted on the second mounting plate, and a second brake pad is fixedly mounted on the movable end of the second adjusting telescopic rod.

[0009] By adopting the above technical solution, when the material transport trolley needs to be braked, the operator transmits power to the braking unit through the drive unit on the push rod. The drive unit drives the movable ends of the first and second adjusting telescopic rods to extend synchronously. The movable end of the first adjusting telescopic rod drives the first brake pad to move closer to the brake disc, and the movable end of the second adjusting telescopic rod drives the second brake pad to move closer to the brake disc synchronously, until the first and second brake pads are clamped and fixed to the brake disc on the rotating rod. The friction between the two sets of brake pads and the brake disc prevents the rotating rod from rotating, thereby driving the rotating frame and the wheel to stop, making it easy to brake the material transport trolley.

[0010] Optionally, the brake unit further includes a first connecting pipe; both the rodless cavity of the first adjusting telescopic rod and the rodless cavity of the second adjusting telescopic rod are filled with liquid, and the two ends of the first connecting pipe are respectively connected to the rodless cavity of the first adjusting telescopic rod and the rodless cavity of the second adjusting telescopic rod; the drive unit includes a pressing plate, a drive telescopic rod, and a connecting plate; two sets of push rods are provided, respectively located on both sides of the vehicle body, and one end of the push rod has a fixing groove; the pressing plate is inclined and one end is hinged to the push rod, and a sliding groove is provided on one side of the pressing plate; the drive telescopic rod is vertical The drive telescopic rod is straight and its fixed end is embedded in the push rod. The rodless cavity of the drive telescopic rod is filled with liquid and is connected to the first connecting pipe through a pipe. A first spring is provided in the rodless cavity of the drive telescopic rod, and the two ends of the first spring are fixedly connected to the movable end and the fixed end of the drive telescopic rod, respectively. A sliding block is rotatably provided on the movable end of the drive telescopic rod. The sliding block is located in the sliding groove and is slidably connected to the extrusion plate. One end of the connecting plate is located in the sliding groove and is slidably connected to the extrusion plate. A fixing block is fixedly provided on one side of the connecting plate.

[0011] By adopting the above technical solution, when the material transport trolley needs to be braked, the operator presses the squeezing plate. The squeezing plate squeezes the movable end of the drive telescopic rod through the sliding block. The first spring is in a compressed state, and the liquid in the rodless cavity of the drive telescopic rod flows through the pipe to the first connecting pipe. The first connecting pipe synchronously distributes the liquid to the rodless cavities of the first and second adjusting telescopic rods. The volume of the rodless cavities of the first and second adjusting telescopic rods increases, and the movable ends of the first and second adjusting telescopic rods extend. The movable end of the first adjusting telescopic rod drives the first brake pad to abut against the brake disc, and the movable end of the second adjusting telescopic rod drives the second brake pad to abut against the brake disc, making it easier for the brake disc to brake and the rotating rod to rotate, thus making it easier to brake the material transport trolley. When the material transport trolley is in a braking state, the connecting plate is in a vertical state. The operator drives the connecting plate to slide towards the push rod, and the connecting plate drives the fixing block to slide into the fixing groove, thereby locking the state of the material transport trolley.

[0012] Optionally, the pushing assembly includes a drive screw, a drive block, and a corrugated protective tube; an installation groove is provided on the inner side wall of the vehicle body; the drive screw is horizontally disposed in the installation groove and rotatably connected to the vehicle body; the drive block is located in the installation groove and threadedly connected to the drive screw, and a push plate is fixedly disposed on one side of the drive block; the corrugated protective tube is horizontally disposed in the installation groove, and its two ends are fixedly connected to the vehicle body and the drive block, respectively.

[0013] By adopting the above technical solution, when the material trolley needs to unload, the locking component releases the locking of the unloading plate. The operator rotates the drive screw. Since the drive block is threadedly connected to the drive screw and cannot rotate due to the restriction of the mounting groove, the rotation of the drive screw is converted into the horizontal movement of the drive block along the mounting groove. The drive block drives the push plate to move synchronously. The corrugated protective tube is always located between the push plate and the unloading plate, making it difficult for material debris to adhere to the drive screw. The push plate pushes the material in the trolley body to move towards the unloading plate, making it easy for the material to be pushed out of the trolley body.

[0014] Optionally, the locking assembly includes a locking telescopic rod; a locking groove is provided on one side of the feed plate, the locking telescopic rod is horizontally arranged, and the fixed end is embedded in the vehicle body, while the movable end of the locking telescopic rod is located in the locking groove.

[0015] By adopting the above technical solution, when the material trolley needs to unload, the operator drives the movable end of the locking telescopic rod to retract. When the movable end of the locking telescopic rod is disengaged from the locking groove, the unloading plate rotates under its own weight, making it easier for the unloading plate to open one side of the vehicle body when unloading.

[0016] Optionally, the locking assembly further includes a gear, a rack, an unlocking telescopic rod, and a second connecting pipe; a clearance groove is provided in the vehicle body, the gear is fixedly mounted on the drive screw and located within the clearance groove; the rack is located within the clearance groove and is slidably connected to the vehicle body, and the rack meshes with the gear; the unlocking telescopic rod is located within the clearance groove, and its fixed end is fixedly connected to the vehicle body; the movable end of the unlocking telescopic rod is fixedly connected to the rack, and the rodless cavity of the unlocking telescopic rod is filled with liquid; a second spring is provided in the rodless cavity of the unlocking telescopic rod, and the two ends of the second spring are fixedly connected to the movable end and the fixed end of the unlocking telescopic rod, respectively; the rod cavity of the locking telescopic rod is filled with liquid, and the two ends of the second connecting pipe communicate with the rodless cavity of the unlocking telescopic rod and the rod cavity of the locking telescopic rod, respectively.

[0017] By adopting the above technical solution, when the operator drives the drive screw to rotate, the drive screw drives the gear to rotate synchronously, the gear drives the rack to move along the length direction of the relief groove, the rack pushes the movable end of the unlocking telescopic rod, the movable end of the unlocking telescopic rod retracts, the second spring is in a compressed state, the liquid in the rodless cavity of the unlocking telescopic rod flows through the second connecting pipe to the rod cavity of the locking telescopic rod, the volume of the rod cavity of the locking telescopic rod increases, the movable end of the locking telescopic rod retracts, making it easy for the movable end of the locking telescopic rod to disengage from the locking groove.

[0018] Optionally, the rod-side chambers of the first and second adjusting telescopic rods are filled with liquid. A third connecting pipe is connected to the rod-side chamber of the first adjusting telescopic rod, and the end of the third connecting pipe away from the first adjusting telescopic rod is connected to the rod-side chamber of the second adjusting telescopic rod. An isolation telescopic rod is installed on the second connecting pipe, the fixed end of the isolation telescopic rod is fixedly connected to the second connecting pipe, and the movable end of the isolation telescopic rod is used to isolate the second connecting pipe. The rod-side chamber of the isolation telescopic rod is filled with liquid and is connected to the third connecting pipe through a pipe.

[0019] By adopting the above technical solution, when the operator drives the material transport trolley to move, the movable end of the isolation telescopic rod isolates the second connecting pipe, so that if the operator accidentally touches the drive screw, the drive screw is not easy to rotate; when the operator drives the material transport trolley to the brake state, the liquid in the rod chamber of the first adjusting telescopic rod and the liquid in the rod chamber of the second adjusting telescopic rod flow through the third connecting pipe and the pipeline to the rod chamber of the isolation telescopic rod, the volume of the rod chamber of the isolation telescopic rod increases, the movable end of the isolation telescopic rod contracts, so that the liquid in the rodless chamber of the unlocking telescopic rod can easily flow through the second connecting pipe to the rod chamber of the locking telescopic rod.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By incorporating a rotating assembly and a braking assembly, the material transport trolley can be easily braked; 2. By setting up a pushing component and a locking component, the material can be easily pushed out of the vehicle body when the material transport trolley is in the braking state.

[0036] When the material trolley is in the braking state, the connecting plate 323 is in the vertical state. The operator drives the connecting plate 323 to slide towards the push rod 11. The connecting plate 323 drives the fixing block 3231 to slide into the fixing groove 111, thereby locking the state of the material trolley.

[0037] Reference Figure 1 The feeding assembly 4 includes a drive screw 41, a drive block 42, and a corrugated protective tube 43.

[0038] Reference Figure 2 and Figure 3 The locking assembly 5 includes a locking telescopic rod 51, a gear 52, a rack 53, an unlocking telescopic rod 54, a second connecting pipe 55, a third connecting pipe 56, and an isolating telescopic rod 57. The locking telescopic rod 51 is horizontally positioned, with its fixed end embedded within the vehicle body 1. The movable end of the locking telescopic rod 51 is located within the locking groove 131, and the rod cavity of the locking telescopic rod 51 is filled with liquid. The gear 52 is fixedly mounted on the drive screw 41 and vertically positioned within the clearance groove 15. The rack 53 is horizontally positioned within the clearance groove 15 and is slidably connected to the vehicle body 1 along its width direction; the rack 53 meshes with the gear 52.

[0039] The unlocking telescopic rod 54 is horizontally positioned within the clearance groove 15, with its fixed end fixedly connected to the vehicle body 1.

The rod-shaped cavity of the isolating telescopic rod 57 is filled with liquid, and the rod-shaped cavity of the isolating telescopic rod 57 is connected to the two sets of third connecting pipes 56 through pipes.

[0041] When the material trolley needs to unload, the operator rotates the drive screw 41. Since the drive block 42 is threadedly connected to the drive screw 41 and cannot rotate due to the restriction of the mounting groove 14, the rotation of the drive screw 41 is converted into the horizontal movement of the drive block 42 along the mounting groove 14. The drive block 42 drives the push plate 421 to move synchronously, and the push plate 421 pushes the material in the trolley body 1 towards the lower material plate 13. At the same time, the drive screw 41 drives the gear 52 to rotate synchronously, and the gear 52 drives the rack 53 to move along the length direction of the clearance groove 15. The rack 53 pushes the movable end of the unlocking telescopic rod 54, and the movable end of the unlocking telescopic rod 54 retracts. The second spring 541 is in a compressed state. The liquid in the rodless cavity of the unlocking telescopic rod 54 flows through the second connecting pipe 55 to the rod cavity of the locking telescopic rod 51. The volume of the rod cavity of the locking telescopic rod 51 increases, the movable end of the locking telescopic rod 51 retracts, and the movable end of the locking telescopic rod 51 disengages from the locking groove 131. The lower material plate 13 rotates under its own weight, and one side of the trolley body 1 is in an open state.

[0042] The implementation principle of a material transport cart with a braking structure according to an embodiment of this application is as follows: When in use, the operator first puts the material to be transferred into the car body 1 with the top opening, and at the same time the operator pushes the push rod 11. The pushing force of the car body 1 drives the rotating rod 22 to rotate. The rotating rod 22 drives the rotating wheel 231 to contact the ground and roll through the rotating frame 23.

[0043] When the material trolley reaches the unloading position and braking is required, the operator presses the squeezing plate 321. The squeezing plate 321, through the sliding block 3222, squeezes the movable end of the drive telescopic rod 322. The first spring 3221 is in a compressed state, causing the liquid in the rodless chamber of the drive telescopic rod 322 to flow through the pipe and the first connecting pipe 315 to the rodless chambers of the first adjusting telescopic rod 313 and the second adjusting telescopic rod 314. The movable ends of the first adjusting telescopic rod 313 and the second adjusting telescopic rod 314 extend. The movable end of the first adjusting telescopic rod 313 drives the first brake pad 3131 to abut against the brake disc 311, and the movable end of the second adjusting telescopic rod 314 drives the second brake pad 3141 to abut against the brake disc 311. At the same time, the liquid in the rod chamber of the first adjusting telescopic rod 313 and the liquid in the rod chamber of the second adjusting telescopic rod 314 flow through the third connecting pipe 56 and the pipe to the rod chamber of the isolation telescopic rod 57. The movable end of the isolation telescopic rod 57 stops isolating the second connecting pipe 55.

[0044] When the material trolley brakes, the operator rotates the drive screw 41. The rotation of the drive screw 41 is converted into the horizontal movement of the drive block 42 along the mounting groove 14. The drive block 42 drives the push plate 421 to move synchronously. The push plate 421 pushes the material in the trolley body 1 towards the lower material plate 13. At the same time, the drive screw 41 drives the gear 52 to rotate synchronously. The gear 52 drives the rack 53 to move along the length direction of the clearance groove 15. The rack 53 pushes the movable end of the unlocking telescopic rod 54. The movable end of the unlocking telescopic rod 54 retracts. The liquid in the rodless cavity of the unlocking telescopic rod 54 flows through the second connecting pipe 55 to the rod cavity of the locking telescopic rod 51.
