Description

Technical Field

[0001] This utility model relates to the field of equipment for loading materials onto ships directly from trucks in thermal power plants, specifically a type of equipment for loading materials onto ships directly from trucks in thermal power plants. Background Technology

[0002] A thermal power plant is a factory that uses combustible materials (such as coal) as fuel to produce electricity. The combustion of fuel produces slag, and flue gas desulfurization produces byproducts such as gypsum. Currently, due to the convenient transportation of coal, most thermal power plants are located along the coast.

[0003] The disadvantages of existing technology are that belt-driven ship loading equipment does not have its own power to move itself and cannot move to the loading position or fixed position by itself, requiring external traction; the single-stage belt can only bear a small amount of material weight, and if the material is too heavy when unloading from the truck, it will cause excessive stress on the belt, or even cause it to tear. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a truck-to-ship material loading equipment for thermal power plants, so as to solve the shortcomings of the prior art mentioned in the background art, namely, that the belt-driven ship loading equipment has no self-powered power to enable its own movement, and cannot move to the loading position or fixed position by itself, requiring external traction; the single-stage belt can only bear a small weight of materials, and if the materials are too heavy when unloading from the truck, it will cause excessive stress on the belt, or even cause it to tear.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a truck direct unloading and ship loading equipment for thermal power plants, including a chassis and a power supply system, wherein the power supply system is installed at the bottom of the chassis;

[0006] A rear walking device is installed below the end of the chassis, and a rear drive device is installed between the chassis and the rear walking device, the rear drive device providing power to the rear walking device.

[0007] A front walking device is installed below the front end of the chassis, and a front steering adjustment device is installed between the front walking device and the chassis. The front steering adjustment device is used for adjusting the direction of the chassis.

[0008] A support frame is mounted on the chassis, and a feeding hopper is mounted on the support frame;

[0009] A plate chain conveyor is mounted on the chassis. The plate chain conveyor is located in the middle of the support frame, and the end receiving position of the plate chain conveyor extends beyond the bottom of the discharge hopper. A conveyor belt is mounted on the chassis. The lower front end of the plate chain conveyor is connected to the upper end of the conveyor belt through a connecting frame. The discharge end of the plate chain conveyor is connected to the receiving end of the conveyor belt.

[0010] Preferably, a second cleaner is installed between the lower part of the plate chain conveyor and the housing, and the second cleaner is used to clean up the accumulated material during the conveying process of the plate chain conveyor.

[0011] Preferably, a scraper is installed between the upper part of the conveyor belt and the housing, and the scraper is used to clean the material adhering to the front of the belt.

[0012] Preferably, a first cleaner is installed between the lower part of the conveyor belt and the housing. The first cleaner is used to prevent material from entering the idler roller through the belt and causing the belt to run off-track.

[0013] Preferably, the plate chain machine is rotatably mounted between the support frames via pins, and an angle adjuster is installed between the chassis and the conveyor belt.

[0014] Preferably, a mechanical dust collector is installed at the front end of the conveyor belt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By manually operating the controller, the power supply system provides power to the rear drive unit, the front steering adjustment unit, the chain conveyor, and the conveyor belt. The rear travel unit on the chassis works in conjunction with the rear drive unit to provide forward power to the chassis. The front travel unit on the chassis works in conjunction with the front steering adjustment unit to change the direction of forward movement. Without the need for external trailers, forklifts, or other transport vehicles, the entire unit can be moved autonomously to the loading position and the fixed position. The chain conveyor and the conveyor belt alternately transport the material discharged from the hopper. The material first comes into contact with and is transported by the rigid chain conveyor, and then it is transported by the conveyor belt. This avoids direct contact between the material and the conveyor belt, reducing the weight of the material on the belt and preventing excessive stress on the belt, which could even cause it to tear.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0024] All components of this utility model are general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0025] See Figure 1-4 This is a schematic diagram of the structure of the present utility model. An embodiment of the present utility model provides a truck-to-ship material loading equipment for thermal power plants, including a chassis 1 and a power supply system 2, wherein the power supply system 2 is installed at the bottom of the chassis 1.

[0026] A rear walking device 3 is installed below the end of the chassis 1, and a rear drive device 4 is installed between the chassis 1 and the rear walking device 3. The rear drive device 4 provides power to the rear walking device 3.

[0027] A front walking device 5 is installed below the front end of the chassis 1. A front steering adjustment device 6 is installed between the front walking device 5 and the chassis 1. The front steering adjustment device 6 is used for adjusting the direction of the chassis 1.

[0028] A support frame 7 is mounted on the chassis 1, and a feeding hopper 8 is mounted on the support frame 7;

[0029] A plate chain machine 9 is mounted on the chassis 1. The plate chain machine 9 is located in the middle of the support frame 7, and the end receiving position of the plate chain machine 9 extends beyond the bottom of the discharge hopper 8. A conveyor belt 11 is mounted on the chassis 1. The lower front end of the plate chain machine 9 is connected to the upper end of the conveyor belt 11 through a connecting frame 10. The discharge end of the plate chain machine 9 is connected to the receiving end of the conveyor belt 11.

[0030] It should be noted that in this embodiment, the power supply system 2 can be a power supply device such as a battery, the rear walking device 3 is composed of two vertical frames and a connecting wheel, and the rear drive device 4 is composed of a connecting seat connected to the chassis 1, a first servo motor, a first driving gear and a first driven gear. The first driven gear is mounted on the long shaft of the wheel, and the first servo motor is powered by the power supply system 2 and its forward and reverse rotation is manually controlled by an external controller.

[0031] The front walking device 5 consists of a U-shaped frame and a coupling wheel. The front steering adjustment device 6 consists of a rotating shaft, bearings, a second driving gear, a second driven gear, and a second servo motor. The rotating shaft is installed at the top center of the U-shaped frame, and the second servo motor is powered by the power supply system 2 and its forward and reverse rotation is manually controlled by an external controller (due to the design of the front and rear wheels, the bottom of the power supply system 2 is far away from the bottom surface to avoid scratches).

[0032] The plate chain machine 9 is a chain conveyor, and the conveyor belt 11 is a belt idler conveyor. Both are existing technologies, so they are not described in detail. Both are powered by the power supply system 2 and their operation is manually controlled by an external controller (before operation, the speed of the conveyor belt 11 is adjusted to be faster than that of the plate chain machine 9 to avoid material blockage).

[0033] Specifically, in use, the power supply system 2 supplies power to the rear drive unit 4, the front steering adjustment device 6, the plate chain conveyor 9, and the conveyor belt 11 through the manual operation of the controller. The rear walking device 3 on the chassis 1 works in conjunction with the rear drive unit 4 to provide forward power to the chassis 1. The front walking device 5 on the chassis 1 works in conjunction with the front steering adjustment device 6 to change the direction of forward movement of the chassis 1. Without the need for external trailers, forklifts, or other transport vehicles, the entire unit can be moved to the loading position and the fixed position by itself. The plate chain conveyor 9 and the conveyor belt 11 alternately transport the material discharged from the unloading hopper 8. The material first comes into contact with and is transported by the rigid plate chain conveyor 9, and then is transported by the conveyor belt 11. This avoids direct contact between the material and the conveyor belt 11, so that the belt bears less weight of material and avoids excessive stress on the belt caused by excessive unloading material, which could even cause the belt to tear.

[0034] A second cleaner 16 is installed between the lower part of the plate chain conveyor 9 and the housing. The second cleaner 16 is used to clean up the accumulated material during the conveying process of the plate chain conveyor 9.

[0035] A scraper 14 is installed between the upper part of the conveyor belt 11 and the housing. The scraper 14 is used to clean the material adhering to the front of the belt.

[0036] A first cleaner 15 is installed between the lower part of the conveyor belt 11 and the housing. The first cleaner 15 is used to prevent material from entering the idler roller through the belt and causing the belt to run off-track.

[0037] The plate chain machine 9 is rotatably mounted between the support frames 7 via pins, and an angle adjuster 13 is installed between the chassis 1 and the conveyor belt 11;

[0038] A mechanical dust collector 12 is connected and installed at the front end of the conveyor belt 11.

[0039] It should be noted that in this embodiment, the second cleaner 16 is composed of a second L-shaped plate, a second rubber plate and a second spring, which can clean the material on the surface of the plate chain machine 9 and avoid long-term material accumulation and blockage.

[0040] The scraper 14 can scrape off the thick material adhering to the surface of the belt, while the first cleaner 15 is composed of a first L-shaped plate, a first rubber plate and a first spring, which can clean off the thin material adhering to the surface of the belt and prevent the material from entering the idler roller through the belt and causing the belt to run off-track.

[0041] The angle adjuster 13 consists of a third servo motor, a threaded rod, a vertical plate, a threaded sleeve plate, a discharge plate, and a connecting block. The connecting block is connected to the bottom of the conveyor belt 11, while the third servo motor and the vertical plate are connected to the chassis 1. The third servo motor is manually controlled to rotate in both directions by an external controller, so that the conveyor belt 11 rotates on the support frame 7 via the plate chain machine 9 connected to the connecting frame 10 through the pin shaft. Adjusting the height of the material feeding end of the conveyor belt 11 can realize the height position of the material feeding.

[0042] The main structural components of the mechanical dust collector 12 (which is existing technology and therefore not described in detail) include the following parts:

[0043] Air inlet: The air inlet is the entrance to the mechanical dust collector, and its main function is to introduce dust-laden gas into the dust collector. The dust-laden gas is dispersed into multiple small airflows to increase the contact area and time between the gas and the filter, thus making it easier to filter dust particles.

[0044] Filters: Filters are the core component of mechanical dust collectors, mainly composed of filter cartridges, filter bags, and filter screens. The function of filters is to remove dust particles from dust-laden gas. Different filter materials and structural forms can be selected according to different operating conditions.

[0045] Exhaust vent: The exhaust vent is the outlet of the mechanical dust collector, and its main function is to discharge the filtered gas. A fan is usually installed at the exhaust vent to ensure stable gas flow and pressure.

[0046] In addition, mechanical dust collectors also include some auxiliary equipment, such as vibrators, dust removal systems, and control systems. These devices ensure the normal operation of the mechanical dust collector and improve dust removal efficiency and operational reliability.

[0047] Differences in structure between different types of mechanical dust collectors:

[0048] Gravity settling chamber: Utilizes gravity to allow dust particles to settle naturally. Its design is simple and suitable for handling larger dust particles. Mechanical dust collector 12 avoids secondary dust generation and environmental pollution during loading and unloading.

[0049] Specifically, during use, the third servo motor is manually controlled to rotate in both directions via an external controller, causing the conveyor belt 11 to rotate on the support frame 7 via the plate chain machine 9 connected to the connecting frame 10 through the pin shaft. Adjusting the height of the material feeding end of the conveyor belt 11 can achieve the high and low feeding positions. The second cleaner 16 is used to clean the accumulated material during the conveying process of the plate chain machine 9. The scraper 14 is used to clean the material adhering to the front of the belt. The first cleaner 15 is used to prevent material from entering the idler roller through the belt and causing the belt to run off-track. The mechanical dust collector 12 avoids secondary dust and environmental pollution during loading and unloading.

[0050] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0051] The working process and principle of this utility model are as follows: During use, the power supply system 2 supplies power to the rear drive unit 4, the front steering adjustment device 6, the chain conveyor 9, and the conveyor belt 11 via manual operation of the controller. The rear walking device 3 on the chassis 1, in conjunction with the rear drive unit 4, provides forward power to the chassis 1. The front walking device 5 and the front steering adjustment device 6 on the chassis 1 work together to change the direction of forward movement. Without the need for external trailers, forklifts, or other transport vehicles, the entire unit can be moved autonomously to the loading position and the designated location. The chain conveyor 9 and the conveyor belt 11 alternately transport the material discharged from the hopper 8. The material first contacts and is transported by the rigid chain conveyor 9, and then... The conveyor belt 11 prevents materials from directly contacting the belt, thus reducing the weight of the materials on the belt and avoiding excessive stress on the belt, which could even cause it to tear. The third servo motor is manually controlled by an external controller to rotate forward and backward, causing the conveyor belt 11 to rotate on the support frame 7 via the plate chain machine 9 connected to the connecting frame 10 through the pin shaft. Adjusting the height of the conveyor belt 11 at the material feeding end can achieve the desired feeding height. The second cleaner 16 is used to clean up the accumulated materials during the conveying process of the plate chain machine 9. The scraper 14 is used to clean up the materials adhering to the front of the belt. The first cleaner 15 is used to prevent materials from entering the idler rollers through the belt and causing belt deviation. The mechanical dust collector 12 avoids secondary dust and environmental pollution during loading and unloading.
