Abstract

The utility model discloses a cargo lift with double guide rail frames, and relates to a cargo lift. The cargo lift comprises a pair of left and right guide rail frames, a pair of left and right transmission mechanisms, a pair of left and right anti-falling safety devices, a pair of left and right regulation rods, a cage, a pair of left and right cushioning devices, a PLC (programmable logic control) device, a pair of left and right wall-attached devices and a pair of left and right frequency converters, wherein the pair of left and right guide rail frames is fixedly arranged in a well through the pair of left and right wall-attached devices; the pair of left and right transmission mechanisms is connected through the pair of left and right regulation rods; gears on the pair of left and right transmission mechanisms move up and down along racks on the pair of left and right guide rail frames; the pair of left and right anti-falling safety devices in opposite directions is arranged on safety plates of the cage; the pair of left and right cushioning devices is arranged at the bottom of the well below the cage; the PLC device and the pair of left and right frequency converters are arranged at the top of the cage; the control signal output ends of the pair of left and right frequency converters are connected with the pair of left and right transmission mechanisms. The cargo lift is stable in running, low in noise, high in safety and carrying capacity, large in cage space and anti-overturning.

Description

A kind of double guide rails Cargo Lift

Technical field

The utility model relates to a kind of Cargo Lift, especially relates to a kind of double guide rails Cargo Lift.

Background technology

The Cargo Lift using in factory building is at present all open side type, its load carrying ability is smaller, the inner space of car is less, and car only have one side be attached on guide rail bracket, safety, stability and the balance of whole Cargo Lift can not meet the demand of present factory building large-tonnage goods.And existing single-column Cargo Lift usually exist due to cargo consolidation one place stack time cause unbalance loading, the area of contact of transmission device, car and guide rail bracket is reduced, contact force increase, make Cargo Lift move not steady, noise is large, rolling wheel wear is serious etc.

Summary of the invention

The purpose of this utility model be to provide have operate steadily, the advantage such as noise is little, safe, car space is large, load carrying ability is large, overturn-preventing, can be widely used in a kind of double guide rails Cargo Lift in the places such as factory building, warehouse.

The utility model is provided with left and right 1 pair of guide rail bracket, 1 pair of left and right transmission device, 1 pair of left and right anti-fall safety device, 1 pair of left and right adjust bar, car, 1 pair of left and right shock absorber, PLC device, 1 pair of left and right wall-attaching equipment and 1 pair of left and right frequency converter;

1 pair of described left and right guide rail bracket is fixed in hoistway by 1 pair of left and right wall-attaching equipment, 1 pair of left and right transmission device connects by 1 pair of left and right adjust bar, gear on the 1 pair of transmission device in left and right moves up and down along the tooth bar on the guide rail bracket of 1 pair of left and right, and 1 pair of the left and right anti-fall safety device of opposite direction is arranged on the safety guard of car; 1 pair of left and right shock absorber is located at the hoistway bottom of car below; The 1 pair of frequency converter in described PLC device and left and right is arranged in car roof, and the control signal mouth of the 1 pair of frequency converter in left and right is connected with 1 pair of left and right transmission device.

Compared with existing open side type Cargo Lift, the form that the utility model changes existing single-column Cargo Lift is double guide rails formula Cargo Lift, car both sides are all provided with guide rail bracket and transmission device, the stressed of Cargo Lift is evenly distributed on double guide rails, load-carrying capacity improves greatly, the center of gravity of whole Cargo Lift can be stabilized between two guide rails, though cage inner space large, carry when heavier and also can guarantee that Cargo Lift operates steadily, guarantee the balance of Cargo Lift.The utlity model has operate steadily, the advantage such as noise is little, safe, car space is large, load carrying ability is large, overturn-preventing, can be widely used in the places such as factory building, warehouse.

Accompanying drawing explanation

Fig. 1 is the structure composition schematic diagram of the utility model embodiment.

The specific embodiment

Referring to Fig. 1, the utility model embodiment is provided with left and right 1 pair of

guide rail bracket

1,1 pair of left and

right transmission device

2,1 pair of left and right

anti-fall safety device

3,1 pair of left and right adjust bar 4,

car
