Problems solved by technology

[0003] Traditional manual pallet trucks often use hand or pedal hydraulic lifts, which have slow lifting speed, high production costs, and poor reliability
The transfer car or hand-pulled luggage cart based on the rotary lifting has a simple structure and fast lifting speed, but most of them have a two-wheel structure, and the wheels are connected with the rotary lifting mechanism. When carrying objects, it is necessary to apply an inclined force, which is inconvenient to use. , it is quite strenuous, and it is difficult to carry larger and heavier items; there are still two defects in its rotary lifting mechanism: one is that during the process of rotating and lifting, the internal items rotate with it, and the vibration amplitude is large. If the items are not fixed, they are easy to dump, causing Damage; the second is that the lifting height is equal to the height of the lowest point of the pallet or cargo support from the ground, and the center of gravity of the cargo is lifted higher, causing more useless work by manpower
The wheel diameters of the two common trucks are usually small, and the passability is poor; in addition, the parameters such as the size of the lifting mechanism lack optimized design, which further affects the performance of the truck

Embodiment 1

[0037] see Figure 1-12 , the present invention provides the following technical solutions: a high-efficiency transport vehicle, including a car body 1, a lifting mechanism 2 is arranged on the car body 1, an adjustable cargo fork 3 is arranged on the lifting mechanism 2, and the lifting mechanism 2 The limit locking mechanism 4 is arranged on the top, and the car body 1 includes a chassis 1.1, a universal wheel with brake 1.2, a directional wheel 1.3, a gas spring fixing seat 1.4, a guardrail 1.5, a rotating frame mounting seat 1.6 and a rotating link mounting seat 1.7 , the inside of the chassis 1.1 is welded with square steel to form a skeleton, and the surface is packaged with steel plates. The front part of the chassis 1.1 is "concave" type, and the middle part is vacant for carrying goods, and the two sides are respectively threaded by four bolts. There are two directional wheels 1.3 connected, and the rear part of the chassis 1.1 is "convex" type. The "convex" structure...

Embodiment 2

[0136] see Figure 13 , the present invention provides the following technical solutions: a high-efficiency transport vehicle, the alternative of its position-limiting locking mechanism is a pedal type, which is divided into two independent parts: an ascending position-limiting locking mechanism 5 and a descending position-limiting locking mechanism 6. The limit locking mechanism 5 is mainly composed of a first unlocking pedal 5.1, an unlocking pedal mounting seat 5.2, a pulley assembly 5.3, a rising locking device 5.4, a locking device mounting plate 5.5 and a height adjustment plate 5.6. The first unlocking pedal 5.1 It is hinged with the unlocking pedal mounting seat 5.2, and the unlocking pedal mounting seat 5.2 is welded under the chassis 1.1. The rising locking device 5.4 is similar to the previous structural principle, and is also composed of a limit pin, a connecting baffle, a return spring and an outer frame. The frame structure is simpler, the side of the outer frame...

Abstract

The invention belongs to the technical field of transport vehicles, in particular to a high-efficiency transport vehicle, comprising a vehicle body, the vehicle body is provided with a lifting mechanism, the lifting mechanism is provided with an adjustable fork, and the lifting mechanism is provided with a limit locking mechanism. In the present invention, by setting up a rotating lifting mechanism based on the "spatially symmetrical parallelogram principle hinged", using gas springs to provide assistance and buffering, according to the proposed size and position parameters and the method of optimizing the selection of gas spring nominal force, the lifting mechanism is designed, and the obtained handling The car has the advantages of fast lifting speed, stable operation, labor-saving and labor-saving; the adjustable fork based on the screw slider mechanism can quickly realize the adjustment of the height and spacing of the fork, and can well match the goods or pallets with different feet, and the applicability Strong; the "hand-held" limit locking mechanism composed of integrated handles, pull ropes, guide plates, locking devices, and limit bolts can realize the position locking and unlocking of rising and falling, and is convenient for single-person operation.

Description

technical field [0001] The invention belongs to the technical field of transport vehicles, and in particular relates to a high-efficiency transport vehicle and a method for optimizing and selecting key parameters thereof. Background technique [0002] Trucks (pallet trucks or luggage carts) can quickly transfer heavy items to the desired location, with large carrying capacity, easy to use, safe and reliable, and are widely used in daily life, as well as wholesale and retail, warehousing logistics, landscaping, machinery Manufacturing and other industries. [0003] Traditional manual pallet trucks often use hand or pedal hydraulic lifts, which have slow lifting speed, high production costs, and poor reliability. The transfer car or hand-pulled luggage cart based on the rotary lifting has a simple structure and fast lifting speed, but most of them have a two-wheel structure, and the wheels are connected with the rotary lifting mechanism. When carrying objects, it is necessary...
