Description

Technical Field

[0001] This utility model relates to the field of construction waste transportation technology, specifically to a device for preventing spillage from construction waste transport dump vehicles. Background Technology

[0002] After construction waste is generated, it needs to be crushed on-site by crushing bulldozers and other equipment, and then transported to designated recycled aggregate sites by construction waste dump trucks. The crushed construction waste contains a large amount of dust. In order to protect the environment and prevent accidental injuries caused by falling construction waste, existing construction waste dump trucks are equipped with tarpaulins, such as CN 221340159. The instruction manual, paragraph 0029, discloses that "...the two sides of the tarpaulin are respectively installed on two sets of multiple mounting rings. Then, the multiple mounting rings and moving tubes are slid onto the wall of the rotating rod, and the two moving tubes away from the rotating rod are left on the wall of the screw rod. At this time, because the multiple moving tubes and mounting rings are close together, the tarpaulin will automatically fold and retract into the protective cover. When it is necessary to cover the tarpaulin, the motor is first started to drive one of the pulleys fixedly connected to the end of its rotating shaft. Then, the belt between the two pulleys drives the two pulleys and the rotating rod to rotate synchronously. Then, the rotating rod drives the screw rod to rotate. At this time, because there are two moving tubes reserved on the screw rod, as the screw rod rotates, the two moving tubes will move synchronously to the side away from the rotating rod, while pulling the tarpaulin and the next moving tube towards the screw rod. When the next moving tube engages with the thread of the screw rod, it will continue to drive the tarpaulin to unfold and pull the next moving tube. In this way, when the first moving tube and mounting ring move to the end of the screw rod, the tarpaulin will completely cover the carriage..."

[0003] The advent of tarpaulin covers has greatly reduced the problem of dust and debris spillage when transporting construction waste by dump trucks. However, the tarpaulin cover and the dump truck are rigidly connected in a covering manner rather than a fully enclosed structure. Therefore, there are gaps at the connection between the two. Due to the inconsistent size of construction waste, gravel particles are trapped in large pieces of construction waste. As the vehicle starts and stops, these gravel particles will roll and seep out from the connection between the tarpaulin cover and the dump truck, causing the construction waste dump truck to spill gravel particles from the gaps while transporting the waste. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a device for preventing spillage from construction waste transport dump vehicles. This device offers advantages such as preventing spillage from construction waste transport dump vehicles equipped with tarpaulin covers, thus solving the aforementioned technical problems.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a device for preventing spillage from a construction waste transport dump vehicle, comprising a cover plate installed at the connection between the truck body and the tarpaulin cover of the construction waste transport dump vehicle. The top of the cover plate is rotatably connected to the outer surface of the truck body via a hinge, and the front wall of the cover plate is in contact with the surface of the truck body. After the cover plate is flipped from bottom to top via the hinge, its rear wall is close to the connection between the truck body and the tarpaulin cover of the construction waste transport dump vehicle. An extension rod is rotatably connected to the bottom of the cover plate, and the tail end of the extension rod is snapped and fixedly installed inside a limiting clip on the outer surface of the truck body.

[0006] As a preferred technical solution of this utility model, a notch is opened at the middle of the bottom of the cover plate, and a crossbar is fixedly installed inside the notch. The top of the extension rod that rotates relative to itself is sleeved on the surface of the crossbar, and a through hole is opened horizontally through the top of the extension rod for rotation relative to the crossbar.

[0007] As a preferred technical solution of this utility model, the limiting card is fixedly connected to the outer surface of the carriage by welding. The limiting card has a through-hole that runs from top to bottom on one side, which is located on the side wall of the limiting card and communicates with the outside. The other side has a latch that is one-third of its own height. When the cover plate is not flipped, the extension rod is engaged in the through-hole. When the cover plate is flipped from bottom to top, the extension rod is engaged in the inside of the latch.

[0008] As a preferred technical solution of this utility model, a collection plate is fixedly installed on the rear wall of the cover plate, that is, the side away from the carriage. The collection plate is a plate body with a semi-circular upper arc and a lower arc connected to the cover plate. The cross-section of the collection plate is hook-shaped.

[0009] As a preferred technical solution of this utility model, the collection plate forms a semi-circular curled-down posture when the cover plate is flipped over by the top hinge, thereby forming a "U"-shaped bend that contacts the surface of the truck body, and the opening of the bend is located directly below the connection between the truck body and the tarpaulin cover of the construction waste transport dump truck.

[0010] As a preferred embodiment of this invention, the collecting plate is made of metal or rubber.

[0011] Compared with the prior art, this utility model provides a device for preventing spillage from construction waste transport dump vehicles, which has the following beneficial effects: 1. This utility model involves holding the extension rod and pushing it upwards, causing the top of the extension rod to move upwards. The top of the extension rod then lifts the bottom of the cover plate. At this point, the cover plate experiences a lifting force from the extension rod below, and simultaneously, the hinge connected to its top begins to rotate around this hinge as an axis. The rear wall of the cover plate then covers the gap between the truck bed and the tarpaulin cover of the construction waste transport dump truck. The extension rod changes from a parallel, flat position against the truck bed surface to a position where the top is away from the truck bed surface and the bottom is close to the truck bed surface, forming a triangular shape with the cover plate. Finally, the bottom of the extension rod is inserted back into the limiting clip at an angle, and the extension rod is then parallel to the cover plate. When the cover plate is placed on the surface of the truck bed, it passes through the limiting clip. When the extension rod changes so that the top is away from the surface of the truck bed and the bottom is close to the surface of the truck bed, the bottom is inserted into the limiting clip. When the cover plate is further flipped, the rear wall of the cover plate flips upward to become the side that fits against the surface of the truck bed. At this time, the collecting plate first contacts the area directly below the connection between the truck bed and the tarpaulin cover of the construction waste transport dump truck, forming a "U" shaped bend. This bend is used to catch the falling gravel particles, so that when the construction waste transport dump truck is transporting construction waste, all the gravel that falls on the road during starting, stopping or bumping will enter the collecting plate, achieving the beneficial effect of preventing spillage of construction waste transport dump trucks with tarpaulin covers.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please see Figure 1-5 A device for preventing spillage from a construction waste transport dump vehicle includes a cover plate 1 installed at the connection between the truck body and the tarpaulin cover of the construction waste transport dump vehicle. The top of the cover plate 1 is rotatably connected to the outer surface of the truck body via a hinge. The front wall of the cover plate 1 is in contact with the surface of the truck body. After the cover plate 1 is flipped from bottom to top via the hinge, its rear wall is close to the connection between the truck body and the tarpaulin cover of the construction waste transport dump vehicle. An extension rod 2 is rotatably connected to the bottom of the cover plate 1. The tail end of the extension rod 2 is snapped and fixedly installed inside the limiting clip 3 on the outer surface of the truck body.

[0018] Currently, when a tarpaulin cover is installed on an existing construction waste transport dump truck, an unavoidable gap exists between the bottom of the tarpaulin cover and the opening at the top of the truck bed. This gap is due to the need for a drive structure to open the tarpaulin cover or a fixing structure to connect it to the opening at the top of the truck bed. Therefore, this gap is an objective reality. After the construction waste is loaded onto the dump truck, the tarpaulin cover is pulled up. At this point, the technical solution of this application can be implemented. By grasping the extension rod 2 and pushing it upwards, the top of the extension rod 2 moves upwards, as shown in the attached instruction manual. Figure 2As shown, the top of the extension rod 2 then lifts the bottom of the cover plate 1. At this time, the cover plate 1 is lifted by the extension rod 2 below, and simultaneously, the hinge connected to its top begins to rotate around the hinge as the axis. At this time, the rear wall of the cover plate 1 close to the connection between the truck bed and the tarpaulin cover of the construction waste transport dump truck covers the gap. At this time, the extension rod 2 changes from a parallel shape attached to the surface of the truck bed to a shape where the top is away from the surface of the truck bed and the bottom is close to the surface of the truck bed, and the extension rod 2 and the cover plate 1 form a triangular posture. Then, the bottom of the extension rod 2 is inserted back into the limiting clip 3 at an inclined angle, as shown in the instruction manual. Figure 1 As shown, when the extension rod 2 is parallel to the surface of the carriage, it passes through the limit card 3. When the extension rod changes to a position where the top is away from the surface of the carriage and the bottom is close to the surface of the carriage, the bottom is inserted into the limit card 3.

[0019] Furthermore, a notch 4 is provided at the bottom center of the cover plate 1, and a crossbar 401 is fixedly installed inside the notch 4. The top of the extension rod 2, which rotates relative to itself, is sleeved on the surface of the crossbar 401. A through hole 201 is provided at the top of the extension rod 2 for rotating relative to the crossbar 401.

[0020] The length is maintained by the crossbar 401 inside the notch 4, allowing the top of the extension rod 2 to move back and forth laterally on the surface of the crossbar 401, thus changing its own position. At the same time, since the top of the extension rod 2 is rotatably connected to the crossbar 401, the lateral movement of the top of the extension rod 2 on the surface of the crossbar 401 will not affect the flipping of the cover plate 1.

[0021] Furthermore, the limit card 3 is fixedly connected to the outer surface of the carriage by welding. The limit card 3 has a through-hole 301 on one side that runs from top to bottom. The through-hole 301 is located on the side wall of the limit card 3 and communicates with the outside. The other side has a latch 302 that is one-third of its own height. When the cover plate 1 is not flipped, the extension rod 2 is engaged in the through-hole 301. When the cover plate 1 is flipped from bottom to top, the extension rod 2 is engaged in the inside of the latch 302.

[0022] Since the extension rod 2 needs to be limited after lifting the cover plate 1, the limiting clip 3 is designed with two openings. One side of the limiting clip 3 has a through-hole 301 extending downwards through itself. The through-hole 301 is located on the side wall of the limiting clip 3 and communicates with the outside, as shown in the instruction manual. Figure 1As shown, when the extension rod 2 is parallel to the surface of the carriage, it passes through the limiting clip 3, that is, it passes through the opening 301. Thus, when the front wall of the cover plate 1 is in contact with the surface of the carriage, the extension rod 2 is placed in the opening 301. Since the opening 301 only passes through vertically, its front and rear areas are the inner walls of the limiting clip 3, thus limiting the extension rod 2 so that it cannot swing back and forth. Further, when the top of the extension rod is away from the surface of the carriage and the bottom is close to the surface of the carriage, the bottom is inserted into the slot 302 on the other side of the limiting clip 3. Since there is a gap between the slot 302 and the opening 301, the extension rod 2 needs to be moved laterally. At this time, the top of the extension rod 2 moves back and forth laterally on the surface of the crossbar 401, so that its own position changes and the position switching of the extension rod 2 is completed.

[0023] Furthermore, a collection plate 101 is fixedly installed on the rear wall of the cover plate 1, that is, on the side away from the carriage. The collection plate 101 is a plate with a semi-circular upper arc and a lower arc connected to the cover plate 1. The cross-section of the collection plate 101 is hook-shaped.

[0024] Furthermore, when the cover plate 1 is flipped over by the top hinge, the collection plate 101 forms a semi-circular curled-down posture, thereby forming a "U"-shaped bend that contacts the surface of the truck body, and the opening of the bend is located directly below the connection between the truck body and the tarpaulin cover of the construction waste transport dump truck.

[0025] The collecting plate 101 is a semi-circular curved plate that is attached to the surface of the truck body at the front wall of the cover plate 1. Once the construction waste dump truck is loaded with construction waste, when the cover plate 1 is flipped over, its rear wall flips upwards to fit against the surface of the truck body. At this point, the collecting plate 101 first contacts the area directly below the connection between the truck body and the tarpaulin cover, forming a "U" shape. This bend is used to catch falling gravel particles. The collecting plate 101 is fixed synchronously with the cover plate 1, so it will not move unless the cover plate 1 is released. After the construction waste dump truck arrives at the landfill, it can reverse and tilt the waste. The hydraulic system of the dump truck lifts the truck body, and the waste tilts from the rear door. At this point, the entire truck body is tilted upwards, and the collecting plate 101 will also begin to slide downwards under the influence of gravity, as shown in the instruction manual. Figure 1 The collection plates 101 between the multiple cover plates 1 are close to each other, forming a complete channel, so that the gravel can be discharged directly from the collection plates 101. Then the carriage can be reset, and the extension rod 2 can be released with its top away from the carriage surface and its bottom close to the carriage surface. When the bottom is inserted into the slot 302 on the other side of the limit card 3, the extension rod 2 is restored to the position where it is parallel to the carriage surface and passes through the opening 301 on one side of the limit card 3. Then the cover plate 1 can be put down. At this time, there is no gravel in the collection plate 101 on the rear wall of the flipped cover plate 1.

[0026] Furthermore, the collection plate 101 is made of metal or rubber.

[0027] The rubber collection plate 101 is elastic and can better fit the surface of the truck body, while the metal collection plate is more durable. Further metals include iron, stainless steel or aluminum. Iron is inexpensive, while stainless steel and aluminum are more corrosion resistant and suitable for long-term outdoor construction waste transport dump trucks. Either one can achieve the technical solution of this application.

[0028] When using, grasp extension rod 2 and push it upwards to move the top of extension rod 2 upwards, as shown in the instruction manual. Figure 2 As shown, the top of the extension rod 2 then lifts the bottom of the cover plate 1. At this time, the cover plate 1 is lifted by the extension rod 2 below, and simultaneously, the hinge connected to its top begins to rotate around the hinge as the axis. At this time, the rear wall of the cover plate 1 close to the connection between the truck bed and the tarpaulin cover of the construction waste transport dump truck covers the gap. At this time, the extension rod 2 changes from a parallel shape attached to the surface of the truck bed to a shape where the top is away from the surface of the truck bed and the bottom is close to the surface of the truck bed, and the extension rod 2 and the cover plate 1 form a triangular posture. Then, the bottom of the extension rod 2 is inserted back into the limiting clip 3 at an inclined angle, as shown in the instruction manual. Figure 1 As shown, when the extension rod 2 is parallel to the surface of the truck body, it passes through the limiting clip 3. When the extension rod changes so that its top is away from the surface of the truck body and its bottom is close to the surface of the truck body, its bottom is inserted into the limiting clip 3. When the cover plate 1 is further flipped, the rear wall of the cover plate 1 flips upward to become the side that is in contact with the surface of the truck body. At this time, the collecting plate 101 first contacts the area directly below the connection between the truck body and the tarpaulin cover of the construction waste transport dump truck, forming a "U" shaped bend. This bend is used to catch the falling gravel particles, so that the construction waste transport dump truck can start and stop on the road when transporting construction waste. All falling gravel, even during bumpy driving, enters the collection plate 101. The collection plate 101 is fixed synchronously with the cover plate 1, so it will not move unless the cover plate 1 is released. After the construction waste dump truck arrives at the landfill, it can reverse and dump the waste. The truck's hydraulic system lifts the cargo compartment, causing the waste to tilt from the rear door. At this point, the entire cargo compartment is tilted upwards, and the collection plate 101, under the influence of gravity, begins to slide downwards, as shown in the instruction manual. Figure 1The collection plates 101 between the multiple cover plates 1 are close to each other, forming a complete channel. The gravel is discharged directly from the collection plates 101. Then the carriage can be reset, and the extension rod 2 can be released with its top away from the carriage surface and its bottom close to the carriage surface. When the bottom is inserted into the slot 302 on the other side of the limit card 3, the extension rod 2 is restored to the position where it is parallel to the carriage surface and passes through the opening 301 on one side of the limit card 3. Then the cover plate 1 can be put down. At this time, there is no gravel in the collection plate 101 on the rear wall of the flipped cover plate 1.
