Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, and in particular to a chain pallet trolley. Background Technology

[0002] Existing sorting machines used in logistics sorting and conveyor lines typically employ narrow belt trolleys for sorting, with the belt resting on pallets and relying on the belt's transmission action to achieve sorting at the corresponding sorting ports.

[0003] When implementing the sorting cart in the prior art, the inventors of this application found the following problems when sorting heavy items: the belts were severely worn and aged, the belts were prone to damage, maintenance was frequent, and maintenance costs were increased. The reason for this is that a large friction force is generated between the belt and the pallet, and under long-term friction, the belt temperature is high and the wear is severe.

[0009] Furthermore, a limit wheel assembly is installed next to the drive wheel and the walking wheel on the same side. The limit wheel assembly includes two limit wheels, which are rotatably connected to the left and right sides of the limit wheel frame via a vertical rotation axis, and the cylindrical surfaces of the two limit wheels abut against the sides of the walking track. The limit wheel frame is fixedly connected to the walking frame.

[0010] Furthermore, an encoder is installed at the bottom of the aforementioned frame.

The double-row chain tracks are arranged on both sides of the transmission frame, the double-row chains are placed inside the double-row chain tracks, and the double-row sprockets that mesh with the double-row chains are rotatably connected to the transmission frame via sprocket shafts. The sprocket shafts are connected to a power mechanism that drives their rotation.

[0012] Furthermore, the aforementioned double-row sprocket has a clamping sprocket on one side and guide wheels of different heights on the other side.

[0013] Furthermore, the aforementioned chain pallet trolley also includes a top cover plate fixedly connected to the frame, and the top cover plate has a strip-shaped opening for a double-row chain transmission mechanism protruding from its top surface.

[0032] The present invention will be further described below with reference to specific embodiments.

[0033] Example 1: As Figure 1-11 As shown, a chain pallet trolley includes a frame 1, a traveling mechanism 2, and a double-row chain conveying mechanism 3. Two double-row chain conveying mechanisms 3 are installed on the left and right sides of the frame 1, respectively. The traveling mechanism 2 is installed at the bottom of the frame 1. Symmetrical side guard plates 6 are installed on both sides of the frame 1. The two side guard plates can limit the sorted goods.

[0034] In this embodiment, reference Figure 8-9As shown, the aforementioned walking mechanism 2 includes a walking frame 201, a drive assembly 202, and a driven assembly 203. The drive assembly 202 and the driven assembly 203 are respectively installed at the front and rear of the walking frame 201. Specifically, the drive assembly 202 includes drive wheels 204, a drive shaft 205, and a reduction motor 206. The two ends of the drive shaft 205 are rotatably connected to the walking frame 201 through bearing seats 207. The walking frame 201 is fixedly connected to the frame 1 within a square. Two drive wheels 204 are used, which are respectively fixedly connected to the two ends of the drive shaft 205. The drive shaft 205 is connected to the reduction motor 206. The driven assembly 203 includes two walking wheels 208. Both walking wheels 208 are rotatably connected to the bottom of the walking frame 201 through wheel frames 209 and correspond to the walking direction of the two drive wheels 204. The wheel frame 209 includes an axle and a mounting plate. The two ends of the axle are fixedly connected to the mounting plate through bearing seats. The mounting plate is fixedly connected to the walking frame 201, and the axle is fixedly connected to the walking wheels 208.

[0035] Specifically, a limit wheel assembly is installed next to the drive wheel 204 and the walking wheel 208 on the same side. The limit wheel assembly includes two limit wheels 210. The two limit wheels 210 are rotatably connected to the left and right sides of the limit wheel frame 211 through a vertical rotation axis, and the cylindrical surfaces of the two limit wheels 210 abut against the sides of the walking track. The limit wheel frame 211 is fixedly connected to the walking frame 201.

[0036] In order to achieve precise walking and positioning of the pallet trolley, an encoder 4 is installed at the bottom of the frame 1. The encoder reads the reading on the grating ruler to obtain the precise walking distance.

[0037] In this embodiment, reference Figure 10-11As shown, the aforementioned double-row chain transmission mechanism 3 includes a transmission frame 301, a double-row chain, double-row sprockets 302, and a double-row chain track 303. The transmission frame 301 is fixedly connected to the traveling frame 201. The double-row chain track 303 is arranged on both sides of the transmission frame 301. The double-row chain is placed inside the double-row chain track 303. The double-row sprockets 302, which mesh with the double-row chain, are rotatably connected to the transmission frame 301 via sprocket shafts 304. The sprocket shafts 304 are connected to a power mechanism that drives their rotation. The double-row chain track 303 has two parallel track grooves. The double-row chain track 303 includes a horizontal section 310 and sections fixedly connected to both ends. At end 311, the power mechanism includes a drive motor 312. The drive motor 312 is fixedly connected to the walking frame 201 via a motor frame 313. The motor shaft of the drive motor 312 is connected to the sprocket shaft 304 via a double-row sprocket transmission mechanism 314. Vertical connecting plates are provided at both ends of the motor frame 313. The vertical connecting plates are fixedly connected to the inner side wall of the frame of the walking frame 201 by screws. The center of gravity of the drive motor 312 is lowered into the walking frame 201. The reduction motor 206 is also located in the frame of the walking frame 201. Because the two motors are relatively heavy, placing their center of gravity in the frame of the walking frame can improve the stability of walking. To tension the double-row chain, a clamping sprocket 305 is provided on one side of the double-row sprocket 302, and guide wheels 306 with different heights on the other side are provided. The clamping sprocket 305 is rotatably connected in the slot of the U-shaped frame 307. A screw 308 is provided in the middle of the bottom side of the U-shaped frame 307. The screw 308 passes through the adjusting frame 309 and is locked with double nuts. The adjusting frame 309 is fixedly connected to the side of the transmission frame 301. Through the clamping sprocket and the guide wheels, the double-row chain and the double-row sprocket can be stably engaged, improving the transmission stability and reliability. When the clamping sprocket moves toward the double-row sprocket side, the double-row chain can be tensioned, and then the double nuts can be locked.

[0038] To improve the safety of cargo transportation, the aforementioned chain pallet trolley also includes a top cover plate 5 fixedly connected to the frame 1. The top cover plate 5 is fixedly connected to the transmission frame 301 by a support column 315. The top cover plate 5 has a strip-shaped opening for a double-row chain transmission mechanism 3 protruding from its top surface. The inlet and outlet ends of the top cover plate are provided with downwardly bent side covers, thereby sealing off the cargo transportation area.

[0039] To clean the travel track, a cleaning brush 7 is installed on the bottom plate of the frame 1, and the cleaning brush 7 is located outside the travel mechanism 2. In order to avoid excessive impact noise and to protect the frame, four buffers 8 are installed on the frame 1, and the buffers 8 are located outside the drive wheel and travel wheel of the travel mechanism 2. The bottom plates on both sides of the frame 1 extend outward and are enclosed by wall panels 10 to form side wall cavities. Electrical equipment can be conveniently arranged in the side wall cavities. Double doors 11 are provided on the side of the wall panels, and warning lights 9 are installed on the top of the side wall cavities.

[0040] In summary, this utility model has the following advantages:
