Description

Technical Field

[0001] This utility model relates to the technical field of unloading safety protection devices, and in particular to an unloading safety protection device for a municipal solid waste transfer station. Background Technology

[0002] As a crucial hub connecting the source of waste generation with the final treatment site, the main function of a municipal solid waste transfer station is to centrally compress and reduce the volume of the scattered municipal solid waste before transferring it to subsequent treatment facilities. During the unloading process, garbage trucks dump the waste into the transfer station's waste pool to prepare for subsequent compression and transfer. The smoothness and safety of this process directly affect the overall operational efficiency of the transfer station and the safety of the workers.

[0003] Currently, among the existing unloading protection devices for municipal solid waste transfer stations, such as the patent with announcement number CN219822495U, this utility model relates to the field of waste treatment, specifically a small waste compression transfer station, including a waste transfer box, a waste compressor and a waste compression chamber. The front and rear sides of the waste compression chamber are provided with compression ports and waste outlets, and the waste compressor is installed at the compression ports.

[0004] It has been found that existing transfer stations have poor protective effects around the garbage pits when vehicles dump garbage, and it is not easy to isolate personnel outside the danger zone during the garbage dumping process, which reduces the safety of the operation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a safety protection device for unloading domestic waste transfer stations that improves personnel safety, reduces the risk of personnel falling into the waste pit, blows leaked waste into the waste pit or moves the waste toward the waste pit during the dumping process, and improves the convenience of personnel cleaning.

[0006] This utility model discloses a safety protection device for unloading waste at a municipal solid waste transfer station, comprising a top plate and supports. The top plate is installed on top of multiple sets of supports and is positioned above the waste pit. It also includes a traction device, a ventilation device, guardrails, guide rails, a ring pipe, and exhaust pipes. The guide rails are mounted on the outer walls of the multiple sets of supports. The guardrails are slidably mounted on the multiple sets of supports via the guide rails and surround the supports. A traction device is installed at the top of the top plate to drive the guardrails to move up and down. The ring pipe is installed on the outer wall of the guardrails. Multiple exhaust pipes are connected to the ring pipe. A ventilation device is installed on the guardrails to supply air to the ring pipes. Internal air supply; when the vehicle stops beside the garbage pit to dump the garbage, the traction device moves the guardrail downwards, so that the guardrail covers and protects the area around the support, thereby preventing other personnel from entering the dumping area and improving the safety of personnel. After the garbage is dumped, the guardrail covers the area around the garbage pit, thereby reducing the risk of personnel falling into the garbage pit. After the garbage is dumped, the air supply device blows air into the annular pipe, so that the annular pipe blows towards the center of the guardrail through multiple sets of exhaust pipes, thereby blowing the garbage that leaked during the dumping process into the garbage pit or moving the garbage towards the garbage pit, improving the convenience of personnel cleaning.

[0007] Preferably, the traction device includes a drive device, traction ropes, guide wheels, limit wheels, winding wheels, and a base. The bottom ends of the two sets of traction ropes are respectively connected to both sides of the guardrail, and the top ends of the two sets of traction ropes are respectively connected to the two sets of winding wheels. The two sets of winding wheels are rotatably mounted on the base, which is mounted on the top of the top plate. The drive device is provided on the base to drive the rotation of the two sets of winding wheels. The two sets of guide wheels and multiple sets of limit wheels are rotatably mounted on the top of the top plate. The traction ropes are guided by the two sets of guide wheels and multiple sets of limit wheels. The drive device drives the two sets of winding wheels to rotate, so that the two sets of winding wheels simultaneously wind or unwind the two sets of traction ropes, thereby enabling the two sets of traction ropes to pull the guardrail up and down, improving the convenience of guardrail movement. The guide wheels and multiple sets of limit wheels guide the two sets of traction ropes, improving the stability of the traction ropes pulling the guardrail.

[0008] Preferably, the driving device includes a worm gear, a worm, and a motor. Two sets of worm gears are respectively installed on the rotating ends of two sets of take-up reels. The worm is rotatably installed on the outer wall of the base and meshes with the two sets of worm gears. The motor is installed on the outer wall of the base and connected to the worm. The motor drives the worm to rotate, which in turn drives the two sets of worm gears to rotate synchronously. This causes the two sets of worm gears to drive the two sets of take-up reels to rotate synchronously. Due to the meshing of the worm gear and the worm, the locking effect of the take-up reel rotation is improved, and the positioning convenience of the guardrail is enhanced.

[0009] Preferably, the air supply device includes a fan, which is installed on the outer wall of the guardrail, and the output end of the fan is connected to the annular pipe; the fan blows air into the annular pipe, which facilitates the sweeping of garbage by multiple sets of exhaust pipes.

[0010] Preferably, it also includes a filter screen, which is connected and installed at the fan inlet; the filter screen filters the air drawn by the fan, reducing the amount of dirt entering the fan.

[0011] Preferably, it also includes gratings, with multiple gratings set on the outer walls of multiple sets of supports; by using multiple gratings to detect objects between multiple sets of supports, the guardrail is prevented from falling and colliding with objects, thus improving safety.

[0012] Preferably, it also includes positioning seats, with multiple sets of positioning seats respectively set at the bottom of multiple sets of brackets; this improves the ease of installation and operation of multiple sets of brackets and enhances the stability of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the vehicle stops at the side of the garbage pit to dump the garbage, the traction device moves the guardrail downward, so that the guardrail covers and protects the area around the support, thereby preventing other personnel from entering the dumping work area and improving the safety protection effect of personnel. After the garbage is dumped, the guardrail covers the area around the garbage pit, thereby reducing the risk of personnel falling into the garbage pit. After the garbage is dumped, the air supply device blows air into the annular pipe, so that the annular pipe blows towards the center of the guardrail through multiple sets of exhaust pipes, thereby blowing the garbage that leaked during the dumping process into the garbage pit or moving the garbage towards the garbage pit, improving the convenience of personnel cleaning.
