Fork truck needs at least two electrical motors, and promptly one is used to drive that the driving wheel that can turn to, one are used for the Hydraulic Pump that descending operation uses and usually another is used for power steering mechanism.The crane and hoist type motor and the electrical motor that travels comprise that their transmission device is arranged in the backplate of a base type, is provided with driver's seat in the above in driver's cab.In the front of driver's seat one space is arranged, it is sealed by a base plate downwards.On base plate, be provided with the pedal of a drg and the pedal of a predetermined speed.
The modern times by battery-driven terrain transportation machinery in mostly adopt three-phase alternating current motor.Therefore need power pack section and control part, so that direct current energy is converted to the three-phase alternating current electric energy.Below it is generically and collectively referred to as power device, wherein also comprise the control corresponding part certainly, control three-phase alternating current motor for mode on request, this is essential.
Power device includes the quartz conductor of high-power ability, and it stands strong heating naturally and therefore must give cooling.So in addition power device forms electromagnetic radiation source.User for power equipment supply requires the radiation of electromagnetic energy and emission to be no more than a value that requires.
Knownly constitute corresponding power of electric motor device small-sized and its housing is provided with a cooling vessel etc., it provides essential cooling for the power device quartz conductor.Two power of electric motor devices that become known for driving with the lifting function are arranged in the space of storage battery top or armrest support below.The space of this storage battery top has less height, because its is determined by the height of driver's armrest support on the other hand by the predetermined altitude of storage battery on the one hand.Though might locate armrest support higher, remaining plane that therefore also must raise, that is the height of driver's seat and base plate.This contradicts with the requirement that should keep fork truck than low height, and it can enter freight container or railway carriage at a puss whereby.Low in addition car door height has advantage, because reduce the accident hazard when getting off.
Under any circumstance must be extremely flat with constituting in the space of power device below armrest support.The mode and the method for the height of this restriction cooling vessel and also restriction ventilation.The shortcoming of the described layout of power device also is and considers, must guide each electrical motor into below the seat from their lead, that is each electrical motor needs three leads with corresponding big cross-sectional area in the three-phase technology.Another shortcoming is there are not enough protection possibilities of anti-electromagnetic-radiation mostly, because requirement decision armrest support aspect design and ergonomics and other backplate are by the plastics manufacturing.
Summary of the invention
The objective of the invention is to, improve fork truck targetedly, make the setting that when the lower system height of fork truck, realizes power device, wherein shorten significantly lead can the length of lead.The ventilation that will make every effort to improve and better protection are with the emission of anti-electromagnetic-radiation in addition.
This purpose reaches by fork truck of the present invention.
By fork truck of the present invention, it comprises: a driver's seat chamber, in this driver's seat chamber, one driver's seat transverse to the fork truck longitudinal axis is set on a base type backplate, and downwards by base plate sealing, an acceleration pedal and a brake pedal are installed at least on this base plate in driver's seat fwd knee space; Also comprise a framework, install on this framework and fixing driver's seat chamber, and this framework is installed one first electrical motor, one second electrical motor and a three-motor on the supporting structure of backplate and floor below, wherein, first electrical motor is used to drive a driving wheel that turns to that is provided with on longitudinal axis, second electrical motor is used for descending operation and three-motor is used to handle the power steering mechanism that driving wheel is used; And be used for each semiconductor power devices of first and second electrical motors with a storage battery bonded assembly, be this first and second motor configurations fan assembly; It is characterized in that, in a space of floor below, limit in the side substrate is installed on the frame part in this space, on this substrate, fix described power device side by side.
In fork truck of the present invention, in a space of floor below, in the side, limit a substrate is installed on the frame part in this space, two power devices are fixed on this substrate side by side.
If fork truck adopts hydraulic brake system, then in floor below one main brake cylinder is set usually, itself is operated when the operation brake pedal.The electrical motor of also known power steering mechanism is arranged in the space of floor below.In fork truck of the present invention, notice other layout of the electrical motor that also can consider power steering mechanism.Though in known situation, turn to of the sprocket wheel co-operating of the electrical motor of servomechanism by the wall plate (Drehschemel) of a chain and steerable wheel, but in fork truck of the present invention, for example can set, make the miniature gears that is installed on the motor reel can be directly and the gear co-operating of bolster.Thereby the electrical motor of power steering mechanism is positioned at the space identical with driving motor.When adopting a kind of electric signal transmitter that is used for speed pedal and brake pedal, it need occupy little space in the installing space of floor below.
Therefore, can provide enough space in order to hold a substrate under above-mentioned prerequisite, two power devices have position arranged side by side on this substrate.
The structure of fork truck of the present invention has a plurality of important advantages.Thereby the installing space that is adopted can not cause the increasing of the bottom-to-top-height of base plate and fork truck, can make it select the height dimension of minimum value on the contrary.This causes a favourable car door height.Each power device can be installed on the substrate in preassembled mode.But also each power device might after installing, be installed by substrate again.If the substrate of steel is welded in the space of floor below, then belong to back one situation.Another advantage is, can be fine and apace near each power device, and this is particularly in maintenance or also reduce expense when changing each power device.Also be favourable aspect the electric wire saving.Two leads that in the accommodating chamber of each power device, need storage battery.The connecting cable that leads to each electrical motor is very short, because they are arranged in the short distance with respect to power device.Do not need touch block in addition.
Another advantage of the present invention is, thereby constituted and guaranteed that satisfied protection avoids the emission of electromagnetism and the influence of radiation by steel part around the space of each power device.In addition advantageously, the car door height of driver's cab is low, reduces accident hazard whereby.Particularly the present invention makes power device can access the actv. cooling.
About the cooling the present invention set a kind of structure, on substrate each power device below below power device the spaced apart fan that is provided with.Certainly the air of being supplied with by fan points to the cooling surface or the cooling vessel of power device by rights, and this is a prerequisite with the corresponding hole in the substrate.Another structure of the present invention is in this respect set, and substrate is divided into compartment (Abteil) below the compartment and above one with the space of floor below, otherwise and fan with air below top compartment is sent into compartment or.The space of floor below is at the width that depends on fork truck aspect the size of its side.Known this width should be hanked different by applicable cases.Irrelevant with the width of fork truck if substrate will have the size consistent with each power device, this is worth laying siege to, and then advantageously substrate is constituted the cross-sectional area in the space that is slightly smaller than floor below.Therefore what conform with purpose is, reservation one gap between a sidewall of substrate and framework, and it is optionally by for example sealing such as a flexiplast lath of a corresponding sealing member, so that separate airtightly each other basically with following compartment top.
Though can imagine air from following suction and upwards carry, this has shortcoming, promptly suck dust and similar dirt and be blown into power pack section easily.Therefore it may cause corrosion and also may make pollution deposit on cooling vessel, thereby reduces heat conductivity.Therefore advantageously, between base plate above the substrate and substrate, suck coolant air., can set by a structure of the present invention, the horizontal edge of the adjacency of cab guard and framework leaves a slit for this reason, borrows its coolant air can flow into top compartment.In order electromagnetic radiation or water etc. not to occur via this slit inside of the top compartment in the ingoing power device from the outside, this by another structure of the present invention advantageously, make the marginal portion of driver's seat chamber backplate and the framework overlap joint that is spaced from each other, and make the air that flows into this space from the outside its flow into this space or above compartment before at first deflect down.This formation of slit requires driver's seat chamber backplate not weld with framework, as it is known, and is connected with the framework screw.Such measure also is known with regard to itself it seems.This slit between driver's cab seat backplate and the framework is considered, electromagnetic screening also is provided in this zone and protects each power device to avoid external influence fully.
For easy Assembly ﹠Disassembly, advantageously substrate is connected on the frame part of side with screw.For this reason, the inner face of frame part, that is the frame part of following qualification battery room can be provided with corresponding bearing rail strip etc., they are welded in this zone.Owing to,, before people can remove these parts, it must be changeed high to the side slightly on the contrary though the simple rising of supporting member and power device is impossible in the formation of this zone inner frame partial sum driver's cab seat backplate.Still reach easy dismounting or installation.
In order to optimize the easy installation of cooling off and reaching fan, a kind of formation of the present invention is set, substrate has two pit shafts that extend downwards, they install the housing or the framework of an axial flow fan on a bottom parts, its middle shell or framework are roughly held by corresponding pit shaft ordinatedly, and the diameter in a hole in the pit shaft base plate roughly is equivalent to the diameter of blower impeller, when each power device is installed on being fixed on each device above the substrate before, at first respectively a fan is positioned in each pit shaft.Though can imagine, realize the fixing of fan by means of screw, but this cause the raising of the bottom-to-top-height of device.Therefore advantageously, connect the housing of fan or framework preferred partly upwards fixing by a kayser by at least one elasticity draw-in groove of well bore wall by a kind of structure of the present invention.
Axial flow fan needs power supply naturally.Therefore outgoing cable must make progress from pit shaft.A kind of structure of the present invention is for this reason set, and the slotted recess that is shaped in abutting connection with the pit shaft place on substrate is so that hold the cable of corresponding cooling fan motor.But also can imagine each independent hole is set in substrate, wherein insert one with fan cable bonded assembly plug.Each hole can form a coding, guarantees whereby, and the plug spare correct position with complementation on substrate is connected with being provided with.
Though can imagine substrate is made by steel.But advantageously adopt plastics according to a kind of structure of the present invention, the plastics that optimum fiber strengthens.But because substrate is only along each end bearing, according to a kind of structure of the present invention advantageously, plastic substrate has reinforced rib to improve bending strength.Reinforced rib is such, promptly particularly makes the high rigidity of maintenance in the substrate center zone, and it prevents that shock and vibration because of car from causing that substrate itself is crossed and vibrating doughtily and suffer damage.
The cooling vessel of known muscle shape is connected with the housing of power device or also can constitutes one with it.In the present invention each power device each rib with cooling vessel is installed on each pit shaft of substrate.Therefore by means of the axial flow fan aspirated air time, the air that is inhaled into arrives fan via the cooling vessel in the pit shaft automatically.Each mineshaft diameter be designed so that cooling vessel with its each rib basically with its covering.
Power device fixing preferably on substrate realized by means of bolt, and the installation of substrate on framework also utilizes bolt to realize.Because substrate should constitute thin as far as possible, advantageously injects the threaded insert that matches with bolt in substrate.At the so-called boss of the regional internal shaping of threaded insert is favourable, and threaded insert embeds wherein.For the amount of deflection that improves the rigidity in the bolted connection zone or substrate is caused because of the stress at bolt place reduces to minimum, according to another structure of the present invention advantageously, screw thread is embedded in and is provided with a radial flange in this zone, above its abuts substrate.The part of cooling vessel or a rib can abut on the flange in such a way, thereby and prevent from the corresponding action of pulling stress infrabasal plate at bolt place undesirable amount of deflection to take place.
One space is arranged below substrate, wherein be provided with hydraulic hose.These hydraulic hoses must can move freely.Therefore the degree of depth in this space is limited in the below of substrate naturally.If yet below this zone, that is with another plate of the spaced apart insertion of substrate be advantageous, it prevents that dust in motion from making progress in the zone of ingoing power device.Be used for the baffle plate that also has of this purpose, it centers on driving wheel and roughly extends to base plate in the driver's seat chamber region.This baffle plate prevents that dust from being entered in the space of floor below by vortex upwards because of driving wheel.
