Description

Lead screw transmission bidirectional carrier

Technical Field

The utility model relates to a transportation equipment technical field specifically is a two-way carrier of screw drive.

Background

When the transport vehicle is used for transporting goods, the goods need to be loaded and unloaded. At present, equipment such as a forklift, a crane, a loader, a belt conveyor and the like are generally adopted according to different goods and packages. When goods are loaded and unloaded outside a goods yard, the equipment needs to be rented to finish operation, but the problems of long waiting time and high cost can occur, even the corresponding equipment can not be rented due to limited resources, and the waiting time is spent, so that the use efficiency of transport vehicles is reduced, and the logistics operation cost is increased, therefore, some goods loading and unloading equipment on vehicles, such as on-vehicle cranes, automobile tailboards and the like, can be transported.

The lorry-mounted crane is usually additionally provided with a forklift bin or a lifting hook on a transport vehicle, is heavy, occupies a transport effective load, increases the oil consumption of the transport vehicle, has higher manufacturing cost, has larger use place limitation, and is not suitable for being installed on a van.

Automobile tailgates are a relatively common type. The tail plate can be installed at the tail part of a transport vehicle and moved along with the vehicle, when goods need to be loaded and unloaded, the goods can be placed on the tail plate, and the goods can be loaded and unloaded by utilizing the up-and-down motion of the tail plate. But the tail plate can only lift the goods up and down and can not carry the goods; and once the tailboard is installed, the weight is large, the disassembly is very troublesome, and the vehicle must drive with the tailboard no matter whether the transportation process is needed, so that the carrying capacity of the vehicle is reduced, the oil consumption is increased, and the transportation cost is increased.

The bidirectional carrying device can be used on a vehicle, bidirectional carrying is achieved, the self weight is light, the occupied space is small, heavy objects are loaded and unloaded, and manual intervention is reduced, so that the main problem of logistics and cargo carrying which needs to be solved at present is solved.

At the present stage, the loading and unloading carrier can be basically carried out on the design concept of a common forklift, and the design of remote control, simplified structure, light weight and the like is added. Hydraulic pressure form fork truck is difficult for realizing compactness and lightweight owing to self structure and weight, can only accomplish the function of going upward moreover mostly, need lean on the action of gravity nature whereabouts down, and it is just unable to realize fast to take time. Other forms of forklifts rely on circulating chains and steel wire ropes to realize up-and-down driving, but the chains and the steel wire ropes are in 'soft' connection, and the strength of a frame must be enhanced to ensure the loading and unloading of heavier goods. The reinforced forklift frame has the defects of being heavy, occupying effective transportation load, increasing the oil consumption of a transportation vehicle, being high in manufacturing cost and the like.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a two-way carrier of screw drive has solved other forms fork truck and has relied on circulation chain, wire rope to realize the vertical drive, but the chain belongs to 'soft' with wire rope and is connected, must strengthen frame intensity and could guarantee heavier goods handling.

In order to achieve the above object, the utility model provides a following technical scheme: including basic frame, activity running gear, motor screw drive pair and the transport mechanism that carries cargo, activity running gear installs in basic frame bottom both sides cover, carry cargo transport mechanism sliding connection in basic frame both sides stand and on the preceding terminal surface, there is the support frame basic frame both sides, install universal supporting wheel in the support frame, and the least of universal supporting wheel is than about four centimetres of bottom protrusion of activity running gear, the transport mechanism both sides that carry cargo all have the fixed connection installed part, installed part sliding connection is in the inboard of basic frame, basic frame bottom fixed mounting has motor screw drive pair, motor screw drive pair's output is connected with the lead screw body, the lead screw body is connected with fork lead screw chain link, fork lead screw chain link fixes in the middle part of the transport mechanism that carries cargo.

Further, a two-way carrier of screw drive, activity running gear includes the connecting plate, connecting plate one end both sides are connected with two slide bars, slide bar one end downside fixed mounting has the walking wheel.

Further, the screw-driven bidirectional carrier comprises a front panel, and load forks are fixedly connected to two sides of the front end of the front panel.

Further, a two-way carrier of screw drive, base frame one end middle part fixed mounting has the removal handle.

Further, a two-way carrier of screw drive, basis frame top fixedly connected with first connecting plate, first connecting plate fixed mounting has the lead screw fixing base, the lead screw body other end is installed in the lead screw fixing base.

As a preferred technical scheme of the utility model, foundation frame top fixedly connected with connecting plate, connecting plate lateral wall fixed mounting has entablature lead screw fixing base, the lead screw body other end is installed in entablature lead screw fixing base.

Compared with the prior art, the utility model provides a two-way carrier of screw drive possesses following beneficial effect:

1. this two-way carrier of screw drive utilizes motor, lead screw pair, and two-way effort can lift, transport goods, also can promote self, realizes getting on or off the bus, also can utilize self elevating system, hangs at the haulage vehicle afterbody, does not occupy the packing box space, can realize transporting carrier self to appointed place or fixed position on the haulage vehicle, and the fitting lifts and adjusts in the suitable product assembly.

2. The screw transmission bidirectional carrier has a simple and compact structure through screw transmission, the overall weight is reduced while the structural height is reduced, and the manufacturing cost is reduced; because the lead screw is used for driving the direct connection structure, the integral rigidity is enhanced, the weight lifting and dead weight ratio is improved, and the condition that the speed of sliding downwards by gravity is unstable is avoided.

3. The screw-driven bidirectional carrier can get on or off the vehicle by means of power of the bidirectional carrier, and the whole process needs about one minute. When the vehicle does not need to be carried in two directions in the whole transportation process, the vehicle can be quickly removed, and the burden of a transportation vehicle is reduced; when the bidirectional carrying vehicle is needed, the bidirectional carrying vehicle is automatically loaded and runs along with the transport vehicle, when the bidirectional carrying vehicle is parked for loading and unloading, the bidirectional carrying vehicle can load or unload the transport vehicle, the loading and unloading functions of a crane, a forklift and the like are realized, the loading and unloading of goods are completed, the types and models of products are complete, and the batch and personalized customization of the products is facilitated.

4. This two-way carrier of screw drive uses the motor, screw drive is vice, the carrier electric energy can the vehicle-mounted supplement, and is both convenient, and is energy-conserving again, can regard as energy storage equipment to use simultaneously, electrical system has reduced artificial intervention in the use, reduce intensity of labour, realize alone, the whole car, an instrument, reduce the cost of labor, both simplify the structure but also steerable stroke scope, strengthen whole car intensity of carrier and rigidity, be favorable to the lightweight and the load promotion of product, guarantee simultaneously that the incident can not appear even the accident loses power yet.
