Description

[Detailed explanation of the idea] The present invention relates to a lift vehicle with a scale.

In order to feed measured raw materials into machines in the plastic molding or chemical industries, the raw materials are first measured using a scale and then transported by a lift truck.

In addition, the hopper of the machine requires taking out the raw material from the top of the lift car, weighing it again, and then feeding a predetermined amount into the machine, which takes time and effort.

The technical problem that the present invention aims to solve is that goods can be weighed and transported using a single lift vehicle, but can be carried without placing an excessive load on the weighing device during transportation, and that it can be carried using a normal lift vehicle. Similarly, the point is that it can be emitted as it is and stably. Another object is to reduce the increase in the bending moment acting on the guide post 2 of the lift vehicle, to ensure strength without increasing the thickness of the component parts, and to reduce the weight of the lift vehicle.

The technical means taken to solve the above technical problem is to provide a lifting platform on the guide post of the lift vehicle so that the lifting platform can be lifted up and down, and to enable the goods to be lifted up and down through links 6 to the lifting platform independently of the lifting and lowering of the lifting platform. A support platform is installed on the lifting platform, a measuring instrument is connected between the two platforms, and a clamp member is installed on either the lifting platform or the article support platform to releasably clamp both platforms. With this structure, it is possible to weigh and transport articles stably.

When the lift table is raised, the article support table is raised via the weighing device, and the articles on the support table can be weighed.

Furthermore, if the two stands are connected and fixed to each other by a clamp member, the measuring instrument will not be shocked by the unevenness of the road surface during transportation, and the measuring instrument will not be damaged.

In addition, the lifting platform 4 is located in front of the guide post in accordance with the length of the link 6, so the torsional moment and bending moment acting on the guide post are large, and the guide post and the part that supports the guide post are not strong. It must be made thicker to increase the

However, since the link 6 is equipped with a roller 43 that rolls on the guide post on the rotation center of the base end, and the link 6 rotates at the position of the guide post 2,
The length of the link 6 can be kept to the minimum length, and as a result, the torsion and bending moment acting on the guide post can be reduced, there is no need to significantly increase the strength of the guide post and its supporting structure, and the weight of the entire lift vehicle can be reduced. increase can be avoided.

The present invention will be specifically described below based on embodiments shown in the drawings.

A frame 1 of the lift vehicle is formed in a U-shape and has wheels 11 at the four corners.

A pair of vertical guide posts 2, 2 having guide grooves 21 formed on opposing surfaces thereof are arranged on the frame 1.

Between both guide posts 2 are a plurality of connecting rods 3, 31.
A hand handle 32 is provided rearwardly protruding from a connecting rod 31 at the center, and an elevating platform 4 is provided between the guide posts 2 and 2.

The lifting platform 4 is composed of a hanging post 41 projecting upward from the center of a rectangular base frame 42, and rollers 43, 43 protruding from both sides of the base frame 42 are rolled into the guide grooves 21 of the guide post 2. It fits in as much as possible.

The hanging post 41 raises and lowers the lifting platform 4, which is connected to a lifting drive device 8, for example, a manual pump type hydraulic cylinder device 81, arranged on the frame 1, along the guide post 2. The upper end of the hanging post 41 is bent forward, and the measuring instrument 7 is suspended from the bent portion 44 via a hanging ring 45.

Article support frame 5 to be described later below the hanging post 41
A clamp member 9 is provided to releasably clamp the.

The clamp member 9 can have various configurations, but for example, parallel thick plates 91, 91 are provided protruding from the front surface of the hanging post 41, and the tips of the thick plates 91, 91 are connected by a connecting plate 92. An internally threaded cylinder 93 is provided to protrude from one thick plate 91.

A long tightening shaft 95 having a threaded shaft 94 at its tip end is screwed into the internal threaded cylinder 93, and a handle 96 is provided at the base end of the shaft 95.

The base end side of the tightening shaft 95 is rotatably supported by a receiving plate 97 that projects laterally from the hanging post 41.

A pair of parallel links 6, 6, 6, 6 are pivoted forward on both sides of the base frame 42, and the article support stand 5 is pivotally connected to each link.

The article support stand 5 has a pair of parallel receiving claws 52, 52 on both sides of the lower end of a rectangular frame 51 supported by the link 6.
The upper end of the rectangular frame 51 is connected to the measuring instrument 7 via a hanging ring 45 at the center of the upper end of the rectangular frame 51 .

A clamp plate 54 is provided upwardly projecting from the center of the lower end of the rectangular frame 51, and the plate 54 is slidably fitted between both thick plates 91, 91 of the clamp member 9 on the lifting table 4.

Rolls 53, 53 are pivotally supported on the receiving claws 52, 52 of the article support stand 5 in the longitudinal direction of the claw plate.

However, a lift vehicle was thrust into the drum can lying on its side from the bottom side of the drum can D, and the drive device 8
The lifting platform 4 is raised by the following steps.

When the drum D rises from the floor surface, the support stand 5 is displaced downward from the lifting table 4 according to the weight of the drum, and the weight is displayed on the scale 7.

When the weighing is finished, the drum is lowered to the floor again, or the clamping shaft 95 of the clamping member 9 is rotated during the weighing state, and the clamping plate 54 of the support base 5 is fixed at the tip of the shaft. The lifting platform 4 and the article support platform 5 are connected and fixed.

As a result, the scale 7 is fixed between the lifting platform 4 and the support platform 5 and is not affected by load fluctuations, so the lifting platform 4 is raised to the required height, and the lift truck is pushed to move the drum to the specified position. Can be transported to the location.

At this time, the weight of the drum is fixed to the scale 7 as a static load, and the scale 7 will not be shocked due to unevenness of the road surface during transportation, and the scale will not be damaged. Since the lifting drive device 8 is connected to the upper part of the hanging post 41 and the lifting platform 4 is moved up and down, the base frame 42 only moves up and down by fitting into the vertical guide post 2, and the load of the cargo is not directly carried. The structure can be made thin and lightweight, and the width of the device can be made thin.

Furthermore, since the upper part of the load support stand 5 is suspended from the upper end of the hanging post via the scale, there is an advantage that the load placed on the support stand and raised can be carried out stably. By disposing rollers 53, 53 on the supporting surfaces of the pair of receiving claws 52, 52 that support the drum, the drum D is rotated with the drum D floating above the floor, and the mouth hole of the drum is positioned downward. This is convenient for releasing the contents.

Incidentally, when implementing the present invention, it is of course possible to provide a clamp member 9 on the support base 5 and clamp the support base 5 and the lifting base 4.
