Description
Technical field
The utility model relates to a kind of mobile grounding rail bound robot, is applied to the mobile grounding of rail mobile robot and mobile power supply technique field.
Background technology
Ground connection is for ensureing that robot normally works and personal safety and a kind of safety measures for power consumption of taking, and to be connected with earth system by plain conductor and to realize, that commonly uses has protective grounding, working earthing, lightning grounding, shield earthing, anti static grounding etc.Drain current issuable on robot metal case, static charge and lightning current etc. are introduced underground by earth system, thus avoid the accidents such as person electric shock and contingent fire, blast.For rail mobile robot, earth system cannot use fixed mode.Ground terminal needs to move together with equipment.Now, rail mobile device mainly uses sliding type ground connection boots to realize slip ground connection.Slip ground connection mainly uses elastomeric material to be pressed onto by derby good for electric conductivity on the track of equipment operation, then needs the place of ground protection to be connected to ensure equipment ground with derby equipment with plain conductor.When the apparatus is in operation, derby draws by equipment push-pull effort, in orbit sliding.But, in order to ensure that good ground connection .(grounding resistance is less than 4 ohm). derby all the time will with track compact siro spinning technology, and grease or lubricating oil can not be smeared to reduce resistance.Earth system will be caused like this after operation a period of time just to there will be heating, and wearing and tearing, bad contact, even scratches the phenomenon of track.
Utility model content
The utility model is just for the deficiency that prior art exists, a kind of mobile grounding rail bound robot is provided, the technical program can actv. solve above-mentioned in bad phenomenon, friction of rolling is used to replace cliding friction, namely the satisfactory electrical conductivity of ground connection can be ensured, also cliding friction can be avoided to cause wearing and tearing to earth system or track, greatly can extend stability and the service life of earth system.
For solving the problem, technical solution adopted in the utility model is as follows:
A kind of mobile grounding rail bound robot, comprise robot body, robot body comprises roller, the endless belt be sleeved on roller, wheel shaft and the wheel carrier that is arranged on wheel shaft, earth system adapter plate is provided with above described robot body, described earth system adapter plate uses screw bolt and nut to be fixed on the top of wheel carrier, and described robot body is connected by wire with earth system adapter plate.
Further, bullet part is also equiped with between wheel carrier and earth system adapter plate.
Further, described roller, endless belt, wheel shaft and wheel carrier are the good metallic material of conduction.
Further, described bullet part is spring or other elastic elements.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
A kind of mobile grounding rail bound robot described in the utility model, friction of rolling is used to replace cliding friction, namely the satisfactory electrical conductivity of ground connection can be ensured, also cliding friction can be avoided to cause wearing and tearing to earth system or track, both the good earth of robot shells be can ensure, stability and the service life of earth system greatly can have been extended again.
Accompanying drawing explanation
Fig. 1 is a kind of mobile grounding rail bound robot structural representation described in the utility model;
Wherein, 1-main body, 2-earth system adapter plate, 3-wire, 4-bullet part, 5-bolt, 6-track, 1-1-endless belt, 1-2-wheel shaft, 1-3-roller, 1-4-wheel carrier.
Detailed description of the invention
Below in conjunction with specific embodiments content of the present utility model is described.
A kind of mobile grounding rail bound robot, comprise robot body 1, robot body comprises roller 1-3, the endless belt 1-1 be sleeved on roller, wheel shaft 1-2 and the wheel carrier 1-4 that is arranged on wheel shaft, earth system adapter plate 2 is provided with above described robot body 1, described earth system adapter plate 2 uses bolt 5 and nut to be fixed on the top of wheel carrier 1-4, and described robot body 1 is connected by wire 3 with earth system adapter plate 2.
Further, bullet part 4 is also equiped with between wheel carrier 1-4 and earth system adapter plate 2.
Further, described roller 1-3, endless belt 1-1, wheel shaft 1-2 and wheel carrier 1-4 are the good metallic material of conduction.
Further, described bullet part 4 is spring or other elastic elements.
As shown in Figure 1, a kind of mobile grounding rail bound robot structural representation, comprises that an endless metal belt 1-1, Metal Contact Rollers 1-3 and metal wheel shaft 1-2 are some, the plain conductor 3 of metal wheel carrier 1-4, connecting device and earth system, bullet part 4, bolt 5 and earth system adapter plate 2.The plain conductor 3 of described endless metal belt 1-1, Metal Contact Rollers 1-3, metal wheel shaft 1-2, metal wheel carrier 1-4 and connecting device and earth system all needs to have good electric conductivity.Described metal wheel shaft 1-2 needs connection metal roller 1-3 and metal wheel carrier 1-4, and the Metal Contact Rollers 1-3 be arranged on metal mounting plate need ensure to rotate freely.The Metal Contact Rollers 1-3 be arranged on metal wheel carrier 1-4 should linearly arrange.It is outside that described endless metal belt 1-1 need be sleeved on Metal Contact Rollers 1-3, and whole endless metal belt 1-1 need strain exceptionally straight by two Metal Contact Rollers 1-3 of outermost end.Described bullet part 4 can be spring, also can select other elastomeric materials.This bullet part 4 is arranged between metal wheel carrier 1-4 and earth system adapter plate 2.Some bolts are used to be connected between earth system adapter plate 2 with metal wheel carrier 1-4.Described bolt is fixed with nut after passing the mounting hole of earth system adapter plate 2 and metal wheel carrier 1-4.The spacing between earth system adapter plate 2 and metal wheel carrier 1-4 can be changed by setting nut, thus the degree of tension of bullet part 4 between regulated ground device adapter plate 2 and metal wheel carrier 1-4.By the adjustment of bullet part 4 degree of tension, the positive pressure between earth system and track 6 can be changed.Described plain conductor 3 connecting device shell and the metal mounting plate of earth system, thus ensure well to be connected with the earth.
From loading angle analysis, the endless metal belt 1-1 propped up by free rotatable metal wheel, is subject to the positive pressure of bullet part 4 between metal wheel carrier 1-4 and earth system adapter plate 2, contacts closely with track 6.When mobile device runs, the friction force contrary with mobile device can be produced between track 6 with endless metal belt 1-1, and the friction force between endless metal belt 1-1 and Metal Contact Rollers 1-3 can make Metal Contact Rollers 1-3 rotate, thus drive endless metal belt 1-1 to rotate.Whole earth system runs just as the Athey wheel of tank on track 6.All the time keep good contact with track 6, but can not produce cliding friction causes some adverse consequencess.
From the angle analysis of electric conductivity, because the thickness of endless metal belt 1-1 can freely be selected, and the area of contact between metal wheel and endless metal belt 1-1 is greater than the face area of a metal wheel all the time.Like this, by the computing formula R=ρ L/S formula of resistance: ρ is the electrical resistivity of material, unit be ohm meter (Ω. m).L is length, and unit is rice (m) S is sectional area, and unit is sq m (m2).
When metal is good conductor, just can ensure that the resistance value of whole earth system is very little in theory.The safety of ground connection can be ensured.
The foregoing is only the preferred embodiments of the present invention, and unrestricted scope of patent protection of the present invention.Every equivalent structure and conversion thereof utilizing content of the present invention, includes within scope of patent protection of the present invention.
