Technical Field

The invention relates to the technical field of logistics industry equipment, in particular to a trolley connecting structure of a linear cross belt sorting machine.

Background

Straight line cross takes sorting machine adopts rubber chain to carry out traction drive dolly tray mostly on the market before, adopts the mode of transition connecting seat between dolly and the chain, and the transition connecting seat carries out two flexible connections through two sets of round pin axle screws, has following several not enough: 1. the stress direction is not tangent to the rubber chain, so that the trolley at the bend part is not stable; 2. the processing cost is higher; 3. the disassembly is inconvenient;

also, as disclosed in chinese patent application No. 201520643926.2, a cart for a cross belt sorter includes a cart frame, a driving roller and a driven roller pivotally mounted at both ends of the cart frame, and a conveyor belt looped around the driving roller and the driven roller; the driving roller includes: a rotating outer drum; a central shaft passing through the outer drum and supported in the outer drum by a shaft; a rotor coil fixed on the central shaft and wound with an excitation coil; a plurality of rare earth magnetic steels which are circumferentially fixed on the inner wall of the outer drum at intervals and surround the periphery of the rotor coil; and the Hall sensors are arranged on the central shaft at intervals and are in control connection with the exciting coil. These problems are usually encountered when the cart structure is installed and connected by using the existing connection structure.

Disclosure of Invention

The invention aims to provide a trolley connecting structure of a linear cross belt sorting machine, which enables the trolley to run more stably.

The technical purpose of the invention is realized by the following technical scheme: a trolley connecting structure of a linear cross belt sorting machine comprises a trolley and a driving chain, wherein a frame of the trolley is connected with the driving chain through a pin shaft extending left and right.

Preferably, a front-rear communication dark channel for the driving chain to pass through and to be sunken upwards from the bottom of the vehicle is formed in the middle of the frame of the trolley.

Preferably, the front-rear communication hidden channel is formed by surrounding a left upright plate, a right upright plate and a top flat plate.

Preferably, the left and right upright plates are provided with left and right through holes for the pin shaft to pass through, the chain link of the driving chain is provided with left and right through chain link mounting holes, and left and right outlets of the chain link mounting holes are respectively opposite to the left and right through holes.

Preferably, the pin shaft comprises a shaft head, a shaft rod and a shaft tail end which are integrally connected.

Preferably, the shaft end is threaded and is fitted with an end locking nut.

Preferably, the space between the left vertical plate and the right vertical plate is smaller than the left-right length of the drive chain link, a left limit lattice blocking sleeve sleeved on the pin shaft is arranged between the left vertical plate and the left side of the drive chain link, and a right limit lattice blocking sleeve sleeved on the pin shaft is arranged between the right vertical plate and the right side of the drive chain link.

Preferably, the left end and the right end of the trolley are respectively provided with a left travelling wheel and a right travelling wheel.

Preferably, the left travelling wheels and the right travelling wheels on the left side and the right side of the trolley are equal in number and are opposite to each other left and right, and the axle centers of the pin shafts are concentric with the axle centers of the left travelling wheels and the right travelling wheels which are opposite to each other left and right.

A linear cross belt sorting machine comprises the trolley connecting structure.

The invention has the beneficial effects that: the trolley is connected by a single pin shaft, the center of the pin shaft is concentric with the center of the first row of travelling wheels, and the trolley is pulled; the concentric advantage is that the radial height change of the turning part is avoided, and the smooth operation and low noise are ensured;

the trolley is pulled by a single pin shaft, the whole group of trolleys has no large impact and runs stably, namely, the stress direction at the bend is tangent to the movement track of the trolley, and the trolley is stable in the turning process by the single pin shaft pulling mode;

simple installation and low cost.
