Description

Technical Field

[0001] This utility model relates to a waste compression device, and more particularly to a safety insurance device for the lifting platform of a vertical waste compressor. Background Technology

[0002] A vertical compression waste transfer station is a municipal solid waste treatment facility that uses a vertical pre-compression process. It compresses loose waste into high-density blocks through a hydraulic system, mainly to improve transfer efficiency and reduce transportation costs.

[0003] The overall structure of a vertical waste transfer station is vertical, employing a vertical compression process. The vertical waste compression system mainly includes a compression unit, a lifting and conveying device, and an electrical system. Its working process is as follows: Before compressing the waste, the transfer vehicle reverses onto the transfer platform to the unloading port, and the lifting transport device rises to the height corresponding to the unloading port. After reversing towards the unloading port, the transfer vehicle uses its self-unloading hydraulic system to rotate the waste container 90 degrees, switching it from a horizontal to an vertical position. This transfers the waste container onto the lifting transport device, which then descends, carrying the waste container. A self-unloading waste unloading truck, loaded with waste, reverses to the back of the transfer vehicle, positioned on the other side of the unloading port. The self-unloading truck releases the waste into the waste container, and the compression device enters to compress it. This process is repeated until the waste container is full. Then, the lifting transport device raises the waste container, which returns to the transfer vehicle under the action of the self-unloading hydraulic system, thus completing the waste compression loading process.

[0004] For the aforementioned vertical waste compression system, when the lifting transport device raises the waste container, regardless of whether the container is empty or loaded with compressed waste, the lifting transport device relies entirely on the hydraulic force provided by the hydraulic system for support. In the empty state, the hydraulic pressure of the hydraulic system can withstand its weight. However, when loaded with compressed waste, the weight is several times that of an empty container, and the seals of the hydraulic cylinders in the lifting transport device may age over time, causing the hydraulic cylinders to lose pressure. Although the lifting transport device can still lift, there is a possibility of slow descent. The hydraulic hoses may also age and break during long-term use. In addition, when the self-unloading hydraulic system transfers the waste container, the rear support of the self-unloading hydraulic system may press against the platform, exceeding the load of the hydraulic cylinders, thereby causing the hoses in the lifting transport device to burst. Utility Model Content

[0005] This invention provides a safety device for the lifting platform of a vertical garbage compressor, which can prevent the oil pipe from bursting under heavy load.

[0006] The technical solutions to the above technical problems are as follows: A safety device for a vertical garbage compactor lifting platform includes a frame enclosing a vertical shaft, a bracket for supporting a garbage container, and a hydraulic cylinder assembly for switching the bracket between a garbage container switching position and a garbage compaction position. The bracket is located within the vertical shaft of the frame and cooperates with the frame. The hydraulic cylinder assembly is connected to the bracket. The device also includes a telescopic component that supports the bracket after it is lifted to the garbage container switching position. The bracket has insertion holes for engaging with the telescopic component. The telescopic component is mounted on the frame, and the portion of the telescopic component that is inserted into the insertion holes slides within the frame. The frame provides support for the portion of the telescopic component inserted into the insertion holes.

[0007] Furthermore, the telescopic assembly includes a bracket, a linear actuator, and a pin. The bracket is fixed to the frame, the linear actuator is fixed to the bracket, the pin is fixed to the linear actuator, and the pin slides in engagement with the frame.

[0008] Furthermore, it also includes sensors for detecting when the bracket reaches the waste container conversion station, and a controller for controlling the extension or retraction of the telescopic assembly. The sensors are connected to the controller, and the controller is connected to the telescopic assembly.

[0009] Furthermore, it also includes a shaft foundation, the frame being fixed to the shaft foundation, and the shaft foundation being provided with one or more supports for supporting the bracket when it runs to the waste compression station.

[0010] Furthermore, it also includes a pulley bracket and a pulley, wherein the pulley bracket is fixed to the bracket, the pulley is mounted on the pulley bracket, and the pulley is in rolling cooperation with the frame.

[0011] In this invention, after the waste container is driven to the waste container conversion position by the hydraulic cylinder assembly, the telescopic component extends and inserts into the insertion hole on the bracket. The telescopic component provides support for the waste container, thereby reducing the load on the hydraulic cylinder assembly and preventing the hydraulic pipe from bursting under heavy load. In this invention, once the waste container rises to the waste container conversion position, the telescopic component is forcibly inserted into the insertion hole on the bracket, providing support for the bracket. This enhances safety during both waste loading and equipment maintenance. Attached Figure Description

Detailed Implementation

[0019] The term "waste" in this utility model refers to household waste, garden waste, agricultural waste, etc. The following is a further detailed description of this utility model in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 6 As shown, the safety device for the vertical garbage compressor lifting platform of this utility model includes a frame 1 surrounding a vertical shaft, a bracket 2 for supporting the garbage container, a hydraulic cylinder assembly 3 for driving the bracket 2 to switch between the garbage container switching position and the garbage compression position, and a telescopic assembly 4 for supporting the bracket 2 after it is lifted to the garbage container switching position. The following is a detailed description of each part and the relationship between them.

[0021] The frame 1 is located within and fixed to the shaft foundation 7 of the waste transfer station. The shaft foundation 7 is provided with one or more supports 8 for supporting the bracket 2 when it moves to the waste compression station. Two supports 8 are arranged at intervals for each station. When the compression device compresses the waste in the container, the bracket 2 is protected from damage by being supported by the supports 8.

[0022] The frame 1 includes multiple columns 1a, tie rods 1b, connecting plates 1c, diagonal braces 1d, and wear-resistant plates 1e. Adjacent columns 1a are fixed to tie rods 1b, and a connecting plate 1c is fixed to the lower end of each column 1a, and the connecting plate 1c is fixed to the shaft foundation 7. One end of the diagonal brace 1d is fixed to a column 1a, and the other end of the diagonal brace 1d is fixed to tie rods 1b. Wear-resistant plates 1e are fixed to two adjacent sides of each column 1a. The wear-resistant plates 1e can be made of polytetrafluoroethylene (PTFE). PTFE has excellent heat and cold resistance, and is resistant to acids and alkalis. Furthermore, PTFE has a low coefficient of friction.

[0023] The bracket 2 is located within the vertical shaft of the frame 1 and cooperates with the frame 1. The bracket 2 is provided with a insertion hole 2a for insertion and cooperation with the telescopic component 4. The bracket 2 includes a support plate 2b, a baffle 2c, a support leg 2d, a connecting frame 2e, and a mounting frame 2f. The baffle 2c is located at the upper end of the support plate 2b and is fixed to the support plate 2b. The support leg 2d is located at the lower end of the support plate 2b and is fixed to the support plate 2b. The insertion hole 2a is preferably located on the support leg 2d. The connecting frame 2e is located on the support plate 2b. On the side, the connecting frame 2e is fixed to the support plate 2b and the baffle 2c respectively, and the mounting frame 2f is fixed to the support plate 2b, the baffle 2c and the connecting frame 2e respectively. The support plate 2b is rectangular. Two mounting frames 2f are installed at each corner of the support 2. The two mounting frames 2f are arranged at a 90° angle. Each mounting frame 2f is fixed with a pulley bracket 9. Each pulley bracket 9 is equipped with a pulley 10. The pulley 10 rolls with the wear-resistant plate 1e in the frame 1.

[0024] The cylinder assembly 3 is connected to the bracket 2. The cylinder assembly 3 includes a cylinder body 3a, a cylinder support 3b, and a protective pipe 3c. The cylinder body 3a and the cylinder support 3b are hinged. The cylinder support 3b is fixed to the well foundation 7 and also to the tie rod 1b in the frame 1. The protective pipe 3c is embedded in the well foundation 7. One end of the cylinder body 3a is inserted into the protective pipe 3c. In this embodiment, the cylinder body 3a is a single-stage cylinder with a relatively long length to meet the lifting requirements of the bracket 2. Therefore, the protective pipe 3c is embedded in the well foundation 7, and one end of the cylinder body 3a is inserted into the protective pipe 3c, thus protecting the cylinder body 3a. The other end of the cylinder body 3a is connected to the bracket 2. The other end of the cylinder body 3a is preferably hinged to the connecting frame 2e in the bracket 2. The hinge allows the cylinder body 3a to adapt to the resistance that the bracket 2 may encounter during the process of driving the bracket 2 to rise and fall, and produces a slight swing, which can prevent the cylinder body 3a from being damaged.

[0025] The telescopic component 4 supports the bracket 2 after it is lifted to the waste container conversion station. The waste container conversion station refers to the following: before the transfer vehicle carrying the waste container reverses into the corresponding station, the hydraulic cylinder component 3 lifts the bracket 2, raising it to the position where the self-unloading hydraulic system releases the waste container onto the bracket 2; or when the waste container is full of compressed waste, the bracket 2 is raised to the position where the self-unloading hydraulic system can extract the waste container. Both positions are at the same height.

[0026] The telescopic assembly 4 is mounted on the frame 1. The portion of the telescopic assembly 4 that is inserted into the insertion hole 2a passes through the frame 1 and slides with the frame 1. The frame 1 provides support for the portion of the telescopic assembly 4 inserted into the insertion hole 2a. The telescopic assembly 4 includes a bracket 4a, a linear actuator 4b, and a pin 4c. The bracket 4a is fixed to the pull rod 1b in the frame 1, the linear actuator 4b is fixed to the bracket 4a, and the linear actuator 4b is preferably a hydraulic cylinder. The pin 4c is fixed to the linear actuator 4b and passes through the frame 1, sliding with the frame 1. In this embodiment, the pull rod 1b has a through hole, in which a guide sleeve 1f is installed. The pin 4c slides with the guide sleeve 1f, and the guide sleeve 1f guides the pin 4c.

[0027] This utility model also includes a sensor 5 for detecting when the bracket 2 reaches the waste receiving container conversion station, and a controller 6 for controlling the extension or retraction of the telescopic component 4. The sensor 5 is connected to the controller 6, and the controller 6 is connected to the telescopic component 4. The controller 6 consists of a chip, a drive circuit, and a solenoid valve. The chip is connected to the drive circuit, and the drive circuit is connected to the solenoid valve.

[0028] The working process of this utility model is as follows: When the transfer vehicle arrives at the garbage transfer station, the hydraulic cylinder assembly 3 lifts the bracket 2, causing the bracket 2 to rise to the garbage container conversion position. At this time, the sensor 5 detects that the bracket 2 has arrived at the garbage container conversion position and sends the detection signal back to the controller 6. The controller 6 controls the linear actuator 4b to work. The piston rod of the linear actuator 4b extends, and the linear actuator 4b drives the pin 4c to move and insert into the insertion hole 2a, thus supporting the bracket 2 through the pin 4c. The transfer vehicle reverses into the unloading position. Using its self-dumping hydraulic system, the transfer vehicle rotates the waste container 90 degrees, switching it from a horizontal to a vertical position, transferring it onto the support frame 2. Then, the controller 6 controls the linear actuator 4b to retract the pin 4c, releasing its support from the support frame 2. The hydraulic cylinder assembly 3 then lowers the support frame 2 to the waste compression position, opening the tailgate of the waste container (tailgate opening is existing technology). The self-dumping waste unloading truck reverses into the unloading position, and the released waste falls into the waste container. The compression device applies pressure to the garbage in the garbage container, compressing the garbage. Once the garbage container is full of compressed garbage, the hydraulic cylinder assembly 3 drives the bracket 2 to rise to the garbage container conversion position. At this time, based on the signal from the sensor 5 that the garbage container has reached the conversion position, the controller 6 controls the linear actuator 4b to work. The piston rod of the linear actuator 4b extends, and the linear actuator 4b drives the pin 4c to move and insert into the insertion hole 2a. The transfer vehicle uses its self-unloading hydraulic system to rotate the garbage container 90 degrees, transferring the garbage container from the bracket 2 to the transfer vehicle, thus completing the loading process of the garbage container.

[0029] After the transfer vehicle reverses towards the unloading port, the lifting transport device descends, and the garbage container descends along with it. The self-dumping garbage truck, carrying garbage, reverses to the back of the transfer vehicle and is positioned on the other side of the unloading port. The self-dumping garbage truck releases garbage into the garbage container, and the compression device enters the container to compress the garbage. This process is repeated until the container is full of compressed garbage. Then, the lifting transport device raises the garbage container, and the container returns to the transfer vehicle under the action of the self-dumping hydraulic system, thus completing the loading of the compressed garbage.
