Description

Technical Field

[0001] The utility model relates to the technical field of coal mine transportation, in particular to an anti-drop device for coal mine transportation. Background Art

[0002] Coal mining usually requires the use of coal mining machines to work, and the coal is transported by coal mining transportation equipment. The existing transportation method is to place the coal collected by the coal mining machine on a cart, and then transport it over a short distance by the cart.

[0003] However, in order to ensure transportation efficiency, the interior of the cart is generally filled very full. However, the current anti-drop device for coal mine transportation lacks an anti-drop device, which causes the coal inside to fall due to being overfilled during transportation, thereby increasing the subsequent cleaning and recycling costs. Therefore, we introduce an anti-drop device for coal mine transportation. Utility Model Content

[0004] The main purpose of the utility model is to provide an anti-falling device for coal mine transportation, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A falling prevention device for coal mine transportation comprises a base, wherein the four corners of the lower end of the base are provided with moving wheels, two push handles are fixedly installed on the left end of the base, a transport frame is provided in the middle of the upper end of the base, and limiting grooves are provided in the middle of the front end and the middle of the rear end of the transport frame, an anti-fall device is provided at the left end of the base, a U-shaped slot is commonly provided at the upper front end, the upper rear end and the upper left end of the base, and a stabilizing device is provided at the lower end of the base.

[0007] Preferably, the anti-fall device includes a mounting frame, a motor is fixedly mounted on the upper end of the mounting frame, a threaded rod is fixedly mounted on the output end of the motor, a driving block is movably mounted on the lower part of the outer surface of the threaded rod, a material blocking frame is fixedly mounted on the right end of the driving block, and limiting blocks are provided in the middle of the inner front wall and the middle of the inner rear wall of the material blocking frame.

[0008] Preferably, the material blocking frame is movably mounted on the outer surface of the threaded rod by driving a block.

[0009] By adopting the above technical solution: when the threaded rod rotates, the driving block can move up and down along the threaded rod, thereby driving the material blocking frame to move accordingly, thereby realizing flexible adjustment of the position of the material blocking frame.

[0010] Preferably, the material blocking frame is movably installed inside the two limiting grooves through limiting blocks, and the inner surface of the material blocking frame is movably fitted with the outer surface of the transport frame.

[0011] By adopting the above technical solution, the material blocking frame can move stably within a specific track through the cooperation between the limiting block and the limiting groove.

[0012] Preferably, the material blocking frame is movably connected to the inside of the U-shaped slot.

[0013] By adopting the above technical solution, the material blocking frame can be easily stored in the U-shaped slot.

[0014] Preferably, the stabilizing device comprises a telescopic cylinder, two of which are provided, a stabilizing plate is commonly fixedly mounted on the output ends of the two telescopic cylinders, a plurality of anti-slip bumps are provided at the lower end of the stabilizing plate, and two fixing grooves are provided at the lower end of the base.

[0015] By adopting the above technical solution: the two telescopic cylinders can drive the stabilizing plate to telescope downward, so that the position of the stabilizing plate can be flexibly adjusted according to actual needs. The anti-slip bumps at the lower end of the stabilizing plate increase the friction and further enhance the stabilizing effect. The two fixing grooves on the base facilitate the fixed installation of the entire device and improve the overall stability and reliability of the device.

[0016] Preferably, the two telescopic cylinders are fixedly installed inside the two fixing grooves respectively.

[0017] By adopting the above technical solution: a stable installation position is provided for the telescopic cylinder to ensure that it will not shake or shift during operation, thereby ensuring the accuracy and reliability of the telescopic action.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. In the utility model, the motor is turned on by the controller, and the two telescopic cylinders make the stabilizing plate move upward, thereby reducing resistance and facilitating the overall movement. The motor drives the threaded rod to rotate, thereby driving the driving block to move upward, thereby driving the material blocking frame at the right end to move synchronously. When the driving block moves upward to the top, the material blocking frame is also located above the outer surface of the transport frame, which is convenient for protecting the coal transported inside and preventing the internal coal from falling during the movement. After being transported to the designated position, the motor is turned on by the controller, so that the driving block drives the material blocking frame to move downward until the driving block moves to the bottom. At this time, the material blocking frame is clamped in the U-shaped card slot for convenient storage.

[0020] 2. In the utility model, two telescopic cylinders are opened through a controller, and the two telescopic cylinders drive the stabilizing plate to move downward, thereby driving a number of anti-skid protrusions below to move downward and contact the ground, thereby making the whole fixed and stable, preventing the whole from shifting or becoming unstable during the loading and unloading process of coal mines.

[0030] A falling prevention device for coal mine transportation comprises a base 1, wherein movable wheels 2 are arranged at the four corners of the lower end of the base 1, two push handles 3 are fixedly installed at the left end of the base 1, a transport frame 4 is arranged at the middle of the upper end of the base 1, and limiting grooves 5 are arranged at the middle of the front end and the middle of the rear end of the transport frame 4, an anti-fall device 6 is arranged at the left end of the base 1, a U-shaped slot 7 is arranged at the front end, the rear end and the left end of the upper end of the base 1, and a stabilizing device 8 is arranged at the lower end of the base 1.

[0031] In this embodiment, the anti-fall device 6 includes a mounting frame 61, a motor 62 is fixedly mounted on the upper end of the mounting frame 61, a threaded rod 63 is fixedly mounted on the output end of the motor 62, a driving block 64 is movably mounted on the lower part of the outer surface of the threaded rod 63, a blocking frame 65 is fixedly mounted on the right end of the driving block 64, and limiting blocks 66 are provided in the middle of the inner front wall and the middle of the inner rear wall of the blocking frame 65; the blocking frame 65 is movably mounted on the outer surface of the threaded rod 63 through the driving block 64; the blocking frame 65 is movably mounted on the inside of the two limiting grooves 5 through the limiting blocks 66, and the inner surface of the blocking frame 65 is movably fitted together with the outer surface of the transport frame 4; the blocking frame 65 is movably clamped in the inside of the U-shaped slot 7.

[0032] Through the above scheme: start the motor 62 to work, and its output end drives the threaded rod 63 to rotate. As the threaded rod 63 rotates, the driving block 64, which is threadedly matched with the threaded rod 63 and limited by the mounting frame 61, moves up and down along the threaded rod 63, thereby driving the right end of the blocking frame 65 to move synchronously. The limit block 66 in the blocking frame 65 cooperates with the two limit slots 5 to ensure the directionality and stability of the movement of the blocking frame 65. At the same time, the inner surface of the blocking frame 65 is movably fitted with the outer surface of the transport frame 4, which can better adapt to the shape of the transport frame 4 and play a role in preventing it from falling. The blocking frame 65 is clamped in the U-shaped clamping groove 7, which further enhances its installation stability and reliability during operation.

[0033] In this embodiment, the stabilizing device 8 includes a telescopic cylinder 81, two of which are provided, and a stabilizing plate 82 is fixedly installed on the output ends of the two telescopic cylinders 81, and a plurality of anti-slip protrusions 83 are provided at the lower end of the stabilizing plate 82, and two fixed grooves 84 are provided at the lower end of the base 1; the stabilizing device 8 includes a telescopic cylinder 81, two of which are provided, and a stabilizing plate 82 is fixedly installed on the output ends of the two telescopic cylinders 81, and a plurality of anti-slip protrusions 83 are provided at the lower end of the stabilizing plate 82, and two fixed grooves 84 are provided at the lower end of the base 1.

[0034] Through the above scheme: the two fixing grooves 84 on the base 1 are used to install the two telescopic cylinders 81, providing a stable installation position for the telescopic cylinders 81. When the whole needs to be fixed, the two telescopic cylinders 81 are started, and their output ends push the commonly connected stabilizing plate 82 to move downward. The anti-slip protrusion 83 at the lower end of the stabilizing plate 82 can increase the friction with the ground, so that the overall stabilization effect is better.

After moving to the designated location, the two telescopic cylinders 81 are opened by the controller. The two telescopic cylinders 81 drive the stabilizing plate 82 to move downward, thereby driving the several anti-skid protrusions 83 below to move downward and contact the ground, so that the whole is fixed and stable. By putting the coal into the transport frame 4, when the coal fills the transport frame 4, before moving, the two telescopic cylinders 81 and the motor 62 are opened again by the controller, and the two telescopic cylinders 81 make the stabilizing plate 82 upward, thereby reducing resistance and facilitating As a whole, the motor 62 drives the threaded rod 63 to rotate, thereby driving the driving block 64 to move upward, thereby driving the blocking frame 65 at the right end to move synchronously. When the driving block 64 moves upward to the top, the blocking frame 65 is also located above the outer surface of the transport frame 4, which is convenient for protecting the coal transported inside and preventing the internal coal from falling during the movement. After being transported to the specified position, the motor 62 is turned on by the controller, so that the driving block 64 drives the blocking frame 65 to move downward until the driving block 64 moves to the bottom.
