Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses an automatic change tray dolly for storehouse.

Example 1:

referring to fig. 1 and 2, the tray trolley for the automatic warehouse comprises a trolley body 1, a bidirectional traction mechanism and a limiting block 3. The upper surface of the vehicle body 1 has a bearing surface 11 for placing cargo. The bidirectional traction mechanism is used for controlling the vehicle body 1 to move towards any one of two opposite directions. The limiting block 3 is arranged corresponding to the bidirectional traction mechanism so as to limit the movement of the vehicle body 1 when loading and unloading goods.

The vehicle body 1 is formed by a plurality of square steel members arranged in a substantially rectangular lattice frame shape in a crisscross manner. The vehicle body 1 is divided into a traction part and a follow-up part along a movable direction, and in the embodiment 1, the vehicle body has a central axis, and the extending direction of the central axis is the same as the moving direction of the vehicle body.

The number of the bidirectional traction mechanisms is two, and the two groups of the bidirectional traction mechanisms are respectively arranged at two ends of the vehicle body in the motion direction. Each group of bidirectional traction mechanisms comprises two groups of traction components 2, and the two groups of traction components 2 in the same bidirectional traction mechanism are symmetrically arranged on two sides of the central axis of the vehicle body 1. Each set of pulling elements 2 comprises a pulling element 21 mounted on the pulling part and a caster 22 mounted on the following part. The pulling element 21 may be a part with a hole, such as a lifting ring, to facilitate the application of a pulling force by means of a hook or the like. The pulling force of the pulling piece 21 is exerted obliquely upwards, namely the caster 22 can be pulled to move so as to move the vehicle body 1.

In this embodiment 1, the lifting element 21 is disposed at an end of the lifting element far from the following element in the moving direction, the lifting element 21 is disposed on a square steel side wall perpendicular to the moving direction, specifically, the lifting element 21 includes a slot hole formed in the square steel side wall and having a downward slot opening, and a reinforcing block fixedly connected to the slot hole, the reinforcing block seals an opening of the slot hole side wall, so that the lifting element 21 can bear a large local load.

Correspondingly, the caster 22 is arranged on the side wall of the follow-up part perpendicular to the moving direction, and the rotating shaft of the caster 22 is perpendicular to the moving direction so that the plane of the rotating direction of the caster 22 is parallel to the moving direction.

Referring to fig. 1 and 3, each dragging assembly 2 is correspondingly provided with a limiting block 3. In the single group of traction components 2, the limit block 3 matched with the traction component 2 is fixedly connected on the vehicle body 1 and is positioned on one side of the caster 22 close to the traction piece 21. The length that stopper 3 downwardly extended terminal surface under automobile body 1 is greater than the length that truckle 22 downwardly extended terminal surface under the automobile body 1 to make stopper 3 contradict in subaerial, truckle 22 can suspend in ground. The included angle alpha formed between the connecting line between the lower positions of the limiting blocks 3 and the corresponding lower positions of the trundles 22 and the lower end face of the vehicle body 1 is smaller than 1 degree, so that when the trundles 22 are controlled to be suspended on the ground, the distance between the trundles 22 and the ground is not too large, and the pulling piece 21 on the vehicle body can be switched to a movable state without being subjected to too much pulling force.

In order to reduce the contact of the casters 22 caused by the inclination of the cargo, each caster 22 is correspondingly provided with a barrier 12, and the barrier 12 is fixedly connected to one side of the body 1 where the caster 22 is located and is located right above the caster 22, so that the barrier 12 can be used for isolating the caster 22 from the bearing surface 1. The thickness of the barrier member 12 in the thickness direction of the caster 22 is larger than the thickness of the caster 22.

In order to prevent production accidents caused by the existence of obstacles at the bottom of the plate trailer, the side wall of the trailer body 1 is provided with lower baffle plates 13 close to the trundles 22, the horizontal plane where the bottom surfaces of the lower baffle plates 13 are located is located between the lower side of the bearing surface 11 and the horizontal plane where the lower positions of the trundles 22 are located, the number of the lower baffle plates 13 is two, and the two lower baffle plates 13 are fixedly connected to two sides of the trailer body 1 perpendicular to the moving direction respectively.

In order to facilitate the installation of goods on the bearing surface, the square steel of the side edge of the bearing surface 11 of the vehicle body 1 is provided with a plurality of positioning holes 14, and the positioning holes 14 are arranged on the adjacent side edge square steel in an L shape.

Each positioning hole 14 is detachably fitted with a movable rod 15. Specifically, the movable rod 15 includes an installation portion for mating with the positioning hole 14 and a positioning portion 151 integrally formed at an upper end of the installation portion, and a flange is disposed at a junction of the installation portion and the positioning portion 151 on the movable rod 15. The radius of the flange is larger than that of the positioning hole 14, so that the movable rod protrudes out of the positioning hole 14 when the mounting part is inserted into the positioning hole 14, and the movable rod is convenient to abut against a plate for positioning.

The implementation principle of the embodiment 1 is as follows: the limiting blocks are correspondingly arranged near the trundles, and the bottom surfaces of the limiting blocks are lower than the bottom surfaces of the trundles. When the traction force is relieved, the high position of the vehicle body can naturally fall under the action of gravity to drive the limiting block to fall onto a working plane, so that the wheels are suspended to limit the vehicle; when the traction force is provided for the traction part, the vehicle body gradually inclines until the limiting block is suspended, the truckles fall to the ground, and the scooter moves along with the situation.

Example 2:

referring to fig. 4 and 5, the present embodiment 2 is different from embodiment 1 in that the installation position of the drag assembly is different.

In this embodiment 2, the pulling-up member 21 is disposed on the square steel at the end far away from the following portion in the moving direction, and the pulling-up member 21 is fixedly connected to the side wall of the square steel and close to the position of the limiting block 3. The pulling piece 21 is a solid steel block with a slotted hole, the slotted hole is positioned on the bottom surface of the solid steel block, the solid steel block penetrates through the lower baffle 13, and the horizontal plane where the bottom surface of the steel block is positioned on the upper side of the horizontal plane where the bottom surface of the limiting block 3 is positioned.

The implementation principle of the embodiment 2 is as follows: when providing the tractive power to the piece that leads, the automobile body slopes gradually to the stopper unsettled, the truckle falls to the ground, and the trigger moves, and the hoist cable can play limiting displacement to a certain extent in the both sides of automobile body perpendicular to direction of motion, prevents that the goods from sliding to the both sides of bearing surface perpendicular to direction of motion in the transportation, has played the effect that promotes transportation stability.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
