Description

Technical Field

[0001] This application relates to the field of urban environmental sanitation, and particularly to an auxiliary device for loading and unloading trash cans. Background Art

[0002] Urban environmental sanitation management is the management of the sanitation conditions of roads, public places, garbage, various units and households, etc. under the leadership of the urban government, with the administrative department relying on full-time teams and social forces, in accordance with the law, to create a clean and civilized environment for urban production and life.

[0003] Currently, usually each merchant uniformly loads the garbage into the trash can, or places the trash can on the road, and then the garbage truck collects the garbage in the trash can and transports it to the garbage station for processing. Although the existing garbage trucks are equipped with auxiliary loading and unloading devices, the auxiliary loading and unloading devices only have the functions of lifting and flipping. It is still necessary for sanitation workers to carry the trash can onto the auxiliary loading and unloading device, and then the auxiliary loading and unloading device lifts the trash can and drives the trash can to rotate to dump the garbage into the garbage truck. And sanitation workers need to carry a large number of trash cans onto the auxiliary loading and unloading device in a day, and then carry the dumped trash cans back to their original positions, resulting in a still relatively high labor intensity for sanitation workers. Content of the Utility Model

[0004] In order to reduce the labor intensity of sanitation workers, this application provides an auxiliary device for loading and unloading trash cans.

[0005] An auxiliary device for loading and unloading trash cans provided by this application adopts the following technical solutions:

[0006] An auxiliary device for loading and unloading trash cans includes a bracket, a flipping frame, clamping jaws, a control mechanism, and a video transmission mechanism. The bracket is arranged on the garbage truck, the flipping frame is rotatably arranged on the bracket, the clamping jaws are arranged on the flipping frame and are used for clamping the trash can, the control mechanism is arranged on the bracket and is used for driving the flipping frame to rotate, and the video transmission mechanism is arranged on the bracket and is used for transmitting the position image of the trash can to the cab.

[0007] By adopting the above technical solutions, the sanitation worker drives the garbage truck to the position of the trash can, transmits the position image of the trash can to the cab through the video transmission mechanism, then adjusts the position of the garbage truck so that the clamping jaws are located at the position of the trash can, then clamps the trash can through the clamping jaws, the control mechanism controls the flipping frame to rotate, the flipping frame can drive the clamping jaws to rotate, the clamping jaws can flip the opening of the clamped trash can to face the garbage truck, so that the garbage in the trash can is poured into the garbage truck, and then the control mechanism drives the trash can to be placed back on the ground, the clamping jaws are loosened, and the trash can can be put back, saving the work process of sanitation workers carrying the trash can and effectively reducing the labor intensity of sanitation workers.

[0008] Optionally, a sliding seat is slidably arranged on the bracket along the length direction of the bracket, the turnover frame is rotatably arranged on the sliding seat, a lifting electric push rod is arranged on the bracket, and the piston rod of the lifting electric push rod is connected to the sliding seat.

[0009] By adopting the above technical solution, the piston rod of the lifting electric push rod reciprocates telescopically, which can drive the sliding seat to drive the turnover frame to reciprocate along the length direction of the bracket. The turnover frame drives the clamping jaws to reciprocate, so that the clamping jaws can clamp the trash can and drive the trash can to reciprocate along the length direction of the bracket, making the poured garbage more dispersed in the garbage truck and making the garbage in the trash can easier to pour out.

[0010] Optionally, the control mechanism includes a control motor and a control panel. The control motor is arranged on the sliding seat, the output shaft of the control motor is coaxially connected to the turnover frame, the control panel is arranged in the cab, and the control panel is electrically connected to both the control motor and the lifting electric push rod.

[0011] By adopting the above technical solution, the sanitation worker starts the control motor through the control panel in the cab of the garbage truck. When the output shaft of the control motor rotates, it can drive the turnover frame to rotate. By controlling the start of the lifting electric push rod through the control panel, the turnover frame can be driven to slide, effectively improving the convenience for the sanitation worker to control the sliding and rotation of the turnover frame.

[0012] Optionally, the clamping jaws are slidably arranged on the turnover frame along the width direction of the bracket. A transverse movement electric push rod is arranged on the turnover frame, the piston rod of the transverse movement electric push rod is connected to the clamping jaws, and the transverse movement electric push rod is electrically connected to the control panel.

[0013] By adopting the above technical solution, the sanitation worker controls the start of the transverse movement electric push rod through the control panel. When the piston rod of the transverse movement electric push rod expands and contracts, it can drive the clamping jaws to slide along the width direction of the bracket on the turnover frame, enabling the clamping jaws to move to the position of the trash can and reducing the requirement for the accuracy of the sanitation worker driving the garbage truck to move the clamping jaws to the position of the trash can.

[0014] Optionally, the clamping jaws include a base, clamping arms and a driving member. The base is slidably arranged on the turnover frame and is connected to the piston rod of the transverse movement electric push rod. Two clamping arms are slidably arranged on the base, and the driving member is arranged on the base and is used to drive the two clamping arms to approach or separate from each other.

[0015] By adopting the above technical solution, the piston rod of the transverse movement electric push rod expands and contracts, causing the base to drive the two clamping arms to move to the position of the trash can. Then the driving member drives the two clamping arms to approach each other, and the two clamping arms can clamp the trash can, improving the convenience of clamping the trash can.

[0016] Optionally, a rubber pad is provided on one side of the clamping arm close to the adjacent clamping arm.

[0017] By adopting the above technical solution, the rubber pad increases the friction between the clamping arm and the trash can, thereby enhancing the stability of the clamping of the trash can by the clamping arm, and the rubber pad can provide buffering to reduce the possibility of the clamping arm damaging the trash can.

[0018] Optionally, the driving member includes a driving motor and a bidirectional lead screw. The driving motor is arranged on the base and electrically connected to the control panel. The bidirectional lead screw is coaxially arranged on the output shaft of the driving motor and is threadedly connected to both clamping arms. The directions of the threads of the bidirectional lead screw connected to the two clamping arms are opposite.

[0019] By adopting the above technical solution, the sanitation worker starts the driving motor through the control panel. When the output shaft of the driving motor rotates, it can drive the bidirectional lead screw to rotate, and the bidirectional lead screw can drive the two clamping arms to approach or separate from each other, improving the convenience for the sanitation worker to control the clamping arms.

[0020] Optionally, a lid-lifting mechanism for lifting the lid of the trash can is provided on the flipping frame. The lid-lifting mechanism includes a first electric push rod, a suction cup, a vacuum pump, and a second electric push rod. The first electric push rod is arranged on the flipping frame. The suction cup is hinged to the piston rod of the first electric push rod. The vacuum pump is arranged on the bracket and communicated with the suction cup. The second electric push rod is arranged on the flipping frame. The second electric push rod and the first electric push rod are arranged staggeredly on the flipping frame. The first electric push rod, the vacuum pump, and the second electric push rod are all electrically connected to the control panel.

[0021] By adopting the above technical solution, the sanitation worker first drives the flipping frame to drive the first electric push rod to rotate towards the trash can, and drives the piston rod of the first electric push rod to extend, so that the suction cup abuts against the lid of the trash can. Then, the vacuum pump is started to make the suction cup suck the lid of the trash can. Then, the flipping frame is driven to rotate, and with the extension of the piston rod of the first electric push rod, the suction cup drives the lid of the trash can to rotate away from the opening of the trash can. Then, the piston rod of the second electric push rod is driven to extend and abut against the side of the lid close to the trash can. The vacuum pump is stopped, and the piston rod of the first electric push rod is driven to retract, so that the suction cup withdraws from the lid. Then, the piston rod of the second electric push rod extends, and with the rotation of the flipping frame, the piston rod of the second electric push rod can be driven to rotate the lid away from the trash can, making the trash can in an open state, which is convenient for subsequent driving the trash can to dump garbage.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The flipping frame can drive the clamping jaws to rotate, and the clamping jaws can flip the opening of the clamped trash can towards the garbage truck, so that the garbage in the trash can is poured into the garbage truck. Then, the control mechanism drives the trash can to be placed back on the ground, and the clamping jaws are loosened, so that the trash can can be put back, saving the working process of sanitation workers carrying the trash can and effectively reducing the labor intensity of sanitation workers.

[0024] 2. The flipping frame drives the clamping jaws to move reciprocally, so that the clamping jaws can clamp the trash can and drive the trash can to move reciprocally along the length direction of the bracket, making the poured garbage more dispersed in the garbage truck and making the garbage in the trash can easier to pour out.

[0025] 3. When the piston rod of the second electric push rod extends and cooperates with the rotation of the flipping frame, the piston rod of the second electric push rod can drive the bucket lid to rotate away from the trash can, making the trash can in an open state, which is convenient for subsequently driving the trash can to dump garbage.

Detailed Embodiment

[0029] The following Figure 1-2 will further describe the present application in detail.

[0030] The embodiment of the present application discloses a trash can loading and unloading auxiliary device.

[0031] Refer to Figure 1 , the trash can loading and unloading auxiliary device includes a bracket 1, a flipping frame 2, clamping jaws 3, a control mechanism 4, a video transmission mechanism 5 and a lid lifting mechanism 10.

[0032] Refer to Figure 1 , Figure 2, the bracket 1 is installed at the rear of the garbage truck in an upwardly inclined manner. A sliding seat 6 is slidably installed on the bracket 1 along the length direction of the bracket 1. The sliding direction of the sliding seat 6 is the same as the inclined direction of the bracket 1. A lifting electric push rod 7 is installed on the bracket 1. The piston rod of the lifting electric push rod 7 is connected to the sliding seat 6; the tipping frame 2 is rotatably installed on the sliding seat 6. The clamping jaw 3 is slidably installed on the tipping frame 2 along the width direction of the bracket 1. The clamping jaw 3 is used for clamping the garbage bin. A transverse movement electric push rod 8 is installed on the tipping frame 2. The piston rod of the transverse movement electric push rod 8 is connected to the clamping jaw 3; the control mechanism 4 is installed on the bracket 1. The control mechanism 4 is used to drive the tipping frame 2 to rotate; the video transmission mechanism 5 is installed on the bracket 1. The video transmission mechanism 5 is used to transmit the position image of the garbage bin to the cab.

[0033] The sanitation worker drives the garbage truck to the garbage bin, and transmits the position image of the garbage bin to the cab through the video transmission mechanism 5, so that the sanitation worker can observe the position of the garbage bin in the cab. Then, the position of the garbage truck is adjusted, and the transverse movement electric push rod 8 is controlled to start. The piston rod of the transverse movement electric push rod 8 expands and contracts, so that the clamping jaw 3 moves horizontally on the tipping frame 2, and the clamping jaw 3 is adjusted to the position of the garbage truck. Then, the clamping jaw 3 clamps the garbage bin, and then the piston rod of the lifting electric push rod 7 is controlled to expand and contract, so that the sliding seat 6 drives the tipping frame 2 to rise, and the garbage bin is lifted and aligned with the opening of the garbage truck. The control mechanism 4 then drives the tipping frame 2 to rotate. The tipping frame 2 can drive the clamping jaw 3 to rotate, and the clamping jaw 3 can turn the opening of the clamped garbage bin towards the garbage truck, so that the garbage in the garbage bin is poured into the garbage truck. Then, the control mechanism 4 drives the garbage bin to be placed back on the ground, and the clamping jaw 3 is released, and the garbage bin can be put back. The whole process does not require the sanitation worker to get off the vehicle, saving the work process of the sanitation worker carrying the garbage bin, and effectively reducing the labor intensity of the sanitation worker; and during the process of dumping the garbage, the piston rod of the lifting electric push rod 7 can also be controlled to make reciprocating expansion and contraction, so that the sliding seat 6 drives the tipping frame 2 to move reciprocally, and the tipping frame 2 drives the clamping jaw 3 to move reciprocally, thereby enabling the garbage bin to move reciprocally along the length direction of the bracket 1, making the poured garbage more dispersed in the garbage truck and making the garbage in the garbage bin easier to pour out. At the same time, when adjusting the position of the garbage truck so that the clamping jaw 3 is aligned with the garbage bin, the sanitation worker controls the transverse movement electric push rod 8, so that the clamping jaw 3 slides horizontally on the tipping frame 2 along the width direction of the bracket 1, and the clamping jaw 3 can be accurately aligned with the garbage bin, reducing the requirement for the accuracy of the sanitation worker driving the garbage truck to move the clamping jaw 3 to the position of the garbage bin.

[0034] Refer to Figure 1 、 Figure 2, the jaw 3 includes a base 31, clamping arms 32 and a driving member 33. The base 31 is slidably mounted on the turning frame 2 in the horizontal direction, and two clamping arms 32 are slidably mounted on the base 31; the driving member 33 is mounted on the base 31, and the driving member 33 is used to drive the two clamping arms 32 to approach or separate from each other. The driving member 33 includes a driving motor 331 and a bidirectional lead screw 332. The driving motor 331 is mounted on the base 31, the bidirectional lead screw 332 is rotatably mounted on the base 31, the bidirectional lead screw 332 is coaxially connected to the output shaft of the driving motor 331, the bidirectional lead screw 332 is threadedly penetrated through the two clamping arms 32, and the directions of the threads of the bidirectional lead screw 332 connected to the two clamping arms 32 are opposite.

[0035] The turning frame 2 drives the jaw 3 to rotate to the position of the trash can, so that the two clamping arms 32 are respectively located on both sides of the trash can. Then, the driving motor 331 is started, and the output shaft of the driving motor 331 drives the bidirectional lead screw 332 to rotate, so that the two clamping arms 32 can approach each other and clamp on both sides of the trash can, thereby conveniently and quickly clamping the trash can; controlling the output shaft of the driving motor 331 to rotate in the reverse direction, so that the bidirectional lead screw 332 rotates in the reverse direction, and the two clamping arms 32 move away from each other, so that the clamping of the trash can can be released.

[0036] Refer to Figure 2 , a rubber pad 9 is covered on the side of the clamping arm 32 close to the adjacent clamping arm 32. When the two clamping arms 32 clamp the trash can, the rubber pad 9 abuts against the trash can. Through the characteristics of high elasticity and high friction of the rubber, the rubber pad 9 enhances the friction between the clamping arm 32 and the trash can, improves the stability when the clamping arm 32 clamps the trash can, and the rubber pad 9 can provide buffering when the clamping arm 32 clamps the trash can, reducing the possibility of the clamping arm 32 damaging the trash can.

[0037] Refer to Figure 1 , Figure 2 , the video transmission mechanism 5 includes a camera and a display. The camera is mounted on the bracket 1, the display is mounted in the cab, and the camera is electrically connected to the display. The camera takes pictures of the position of the trash can behind the bracket 1, and then transmits the captured picture to the display for display. The sanitation workers can conveniently observe the position of the trash can in the cab, and then adjust the position of the garbage truck so that the jaw 3 adapts to the position of clamping the trash can.

[0038] Refer to Figure 1 , Figure 2 , the control mechanism 4 includes a control motor 41 and a control panel. The control motor 41 is mounted on the sliding seat 6, the output shaft of the control motor 41 is coaxially connected to the turning frame 2 through a reduction gear set, the control panel is mounted in the cab, and the control panel is electrically connected to the control motor 41, the lifting electric push rod 7, the transverse electric push rod 8, and the driving motor 331.

[0039] The sanitation worker observes the position of the trash can in the cab, and then can control the opening and closing of the control motor 41 through the control panel, so that the control motor 41 drives the rice gripper to rotate. The lifting electric push rod 7 can also be controlled through the control panel, so that the lifting electric push rod 7 drives the flipping frame 2 to move in the length direction of the bracket 1. The transverse moving electric push rod 8 can also be controlled through the control panel, so that the transverse moving electric push rod 8 drives the clamping jaw 3 to move horizontally on the flipping frame 2. The driving motor 331 can also be controlled through the control panel to drive the two clamping arms 32 to clamp or release the trash can. By working together, the trash in the trash can can be brought into the garbage truck, effectively improving the convenience for the sanitation worker to pour the trash in the trash can into the garbage truck.

[0040] Refer to Figure 1 、 Figure 2 As shown in

[0041] Through the control of the control panel, the sanitation worker first drives the flipping frame 2 to drive the first electric push rod 101 and the suction cup 102 to move in the opposite direction close to the lid of the trash can. Then the piston rod of the first electric push rod 101 extends, so that the suction cup 102 abuts against the lid of the trash can. Then, by controlling the start of the vacuum pump 103 through the control panel, the suction cup 102 can suck the lid of the trash can. Then drive the flipping frame 2 to drive the first electric push rod 101 to rotate away from the trash can, and at the same time drive the piston rod of the first electric push rod 101 to continue to extend, so that the suction cup 102 can drive the lid of the trash can to turn away from the trash can. Then control the piston rod of the second electric push rod 104 to extend into the gap between the lid of the trash can and the trash can. The piston rod of the second electric push rod 104 abuts against the side of the lid of the trash can close to the trash can. Then control the vacuum pump 103 to close, and drive the piston rod of the first electric push rod 101 to retract, so that the suction cup 102 withdraws from above the lid. Then continue to drive the piston rod of the second electric push rod 104 to extend, and the lid of the trash can can be pushed away from the trash can, making the trash can in an open state, so that the trash is more likely to fall out of the trash can when the trash in the trash can is poured later.

[0042] The implementation principle of an auxiliary device for loading and unloading trash cans in an embodiment of this application is as follows: The sanitation worker drives the garbage truck to the trash can, observes the position of the trash can through the video transmission mechanism 5, and then controls the lifting electric push rod 7, the lateral movement electric push rod 8, the control motor 41, the first electric push rod 101, the vacuum pump 103, and the second electric push rod 104 through the control panel. First, the lid of the trash can is lifted, and then the lifting electric push rod 7, the lateral movement electric push rod 8, the control motor 41, and the drive motor 331 are controlled again through the control panel, so that the two clamping arms 32 clamp the trash can, and the garbage in the trash can is dumped into the garbage truck. Then, the dumped trash can is placed back on the ground, saving the working process of sanitation workers carrying the trash can and effectively reducing the labor intensity of sanitation workers.

[0043] The above are all preferred embodiments of this application. The protection scope of this application is not limited by this.
