Description

A new type of transport pallet connection and steering device

technical field

The invention belongs to the application field of civil aviation logistics, in particular to a novel connection and steering device between transport pallets which can eliminate the turning gap of a luggage transport pallet group and realize automatic reset of pallet sub-boards.

Background technique

The civil aviation transportation logistics industry is a basic and leading industry of the national economy. Its development speed needs to meet the needs of passenger and cargo displacement, which is of great significance to the social economy; however, with the increasing throughput of civil aviation airports in my country, the current baggage sorting equipment And it is difficult to meet the high-growth demand of logistics, which has become a shackle of the civil aviation transportation industry. The pallet connection device of the current baggage sorting equipment is made of polymer materials, which will generate a lot of friction and noise during the process of filling the gap at the turning point, and it is also easy to cause shrinkage during the movement. If the speed Too fast can also cause a large impact, causing damage to the pallet group.

In the prior art, the Chinese patent No. 201320177024.5 discloses the combined tray technical scheme of the flip-type luggage high-speed automatic sorter. When describing the connection of the tray group to the steering device, an "8" circle structure is provided. There is no way to reset it automatically after it has been scaled down.

Contents of the invention

The purpose of the present invention is to overcome the problem that the combined trays of the existing luggage sorting mechanism cannot be automatically reset, and propose a new transport tray connection and steering device, which can eliminate the turning gap of the luggage transport tray group and automatically reset.

In order to realize above-mentioned technical effect, the present invention adopts following technical scheme:

A new type of connection and steering device between transport pallets, consisting of a pallet main board (1), a pallet sub-board (2) and a connection and steering mechanism; it is characterized in that: the connection and steering mechanism includes a chute block (3), a spring ( 4), the rotating block (6); the spring (4) and the rotating block (6) are placed in the chute of the chute block (3), and the bottom of the chute block (3) is fixedly connected to the tray sub-board (2 ), one end of the spring (4) is fixed at the bottom of the chute, the other end of the spring (4) is connected with the rotating block (6), and the upper end of the rotating block (6) passes through the limit slot (7) of the tray sub-plate (2) ) to connect with the tray main board (1).

In the above scheme, in order to make the rotating block run smoothly in the chute, the lower end of the rotating block is a cuboid, and the upper end is a cylinder.

In the above scheme, the rotating block is a cylinder, the middle of the rotating block is provided with a groove, and the specific way of connecting the spring to the rotating block is as follows: one end of the spring is provided with an annular body, and the annular body is installed in the groove of the rotating block. Can rotate relative to the groove; when the transport pallet connection and steering device of the present invention is working, the spring only moves axially in the chute, and the rotating block can move axially in the chute, and can also rotate around its own axis .

In the above solution, another way of connecting the spring to the rotating block is: one end of the spring bears against the straight-moving slider, and the straight-moving slider bears against the rotating block.

Above-mentioned spring is connected with connecting plate with chute bottom.

In the above solution, the spring is connected to the bottom of the chute with a connecting plate.

In the above solution, the parallel limiting method of the tray sub-board and the tray main board is specifically: adding load-bearing supporting plates on both sides of the sub-board.

In the above solution, the spring is specifically an elastic material or structure with elastic recovery force.

The working principle of the present invention is as follows.

During the straight running process, the gap between the pallet groups is kept constant, and the spring and the rotating block are respectively pressed against the two ends of the chute by the preload of the spring inside the connection and steering device. This state is the initial state of the pallet group. When the pallet group enters the curve from the straight road, the gap between the pallet groups on the inside of the curve decreases, and the gap on the outside becomes larger. The reduction of the internal gap of the pallet group will cause a squeeze between the sliding block and the spring, which will This kind of movement makes the spring shrink, the main board is close to the sub-board, and the rotating block will rotate relative to the main board of the tray at the same time. The above movement makes the two adjacent pallet groups keep fit during the curve movement, eliminating the gap between the pallet groups . When the pallet group turns from the curve to the straight road, it can be regarded as the reverse process of the pallet group from the straight road to the curve. The pressing effect between the sliding block and the spring is reduced, and the spring is gradually reset. Finally restore the initial state of the pallet group.

The advantages of the present invention are as follows.

1. The pallet main board and pallet sub-board can move or rotate relative to each other, which can avoid damage to the mechanism and goods when packing and eliminate the gap between pallets during turning.

2. The spring-rotating block structure is adopted, which eliminates the gap between the pallets during the turning process, and makes full use of the elastic characteristics of the spring, which can be compressed as a buffer element under the action of an external force. When the gap increases, the front and rear pallets are kept in place. The tightness of the fit during the turning process reduces the damage of the pallet group and at the same time realizes the smooth operation of the pallet group.

3. The present invention has a simple and compact structure, is not prone to failure, and is well matched with existing driving and turning devices.
