Description
Technical field
The utility model relates to a kind of novel folding foot rest, belongs to earth moving plant lane device technical field.
Background technology
Excavator, scraper, push or the machineries such as smooth soil and sandstone, all be widely used in building operations, water conservancy construction, road construction etc., must be provided with lane device to be used for auxiliary driver, maintenance personal and attendant's operation on earth moving plant at this type of machinery for this reason, in the place that the passage requirement is arranged foot rest need to be set, and foot rest is installed in car frame side beam one side usually and be positioned at the crawler belt below.Stipulate according to earth moving plant lane device standard GB/T17300, height A on the tread that first order foot rest is arranged and ground can not be higher than 700mm, usually generally should not surpass 600mm in actual applications, and foot-operated face width degree C can not be less than 150mm, the foot rest outside also can not exceed the mandatory requirements such as crawler belt outward flange simultaneously.See shown in Fig. 1～2, on the lower vehicle frame of curb girder, traditional pin pedal 2 is the bending parts that directly are welded on curb girder 1, if crawler belt outward flange and curb girder outer wall distance L and actual tread width S one are regularly, so that not terminating in foot rest 2 spaces own, tread also do not comprise the bending slope, if the actual tread width S on the foot rest 2 is less than or equal to the distance L between curb girder outer wall and the crawler belt outward flange at this moment, can guarantee that the tread of first order foot rest and the height A on ground reach foot-operated face width degree C in critical field.But on the higher vehicle frame of curb girder, especially for the large-tonnage type, for the height A on the tread that guarantees first order foot rest and ground in critical field, foot rest can not be welded to the curb girder bending part, as shown in Figure 3, this moment, the tread width C of foot rest 2 depended on foot rest developed width S fully, and namely foot rest developed width S equals the tread width C, if want the tread width C this moment in critical field, then the foot rest outside then exceeds the crawler belt outward flange.Traditional Foldable pedal has been realized folder function for this reason, but the tread of foot rest developed width S and first order foot rest and the height A on ground are still had certain requirement, and to require the curb girder wall be flat face.Find that in the middle of practical application the applicable scope of lane device is a bit narrow, still may not satisfy actual requirement.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, can take full advantage of the space, and is safe and reliable, can satisfy simultaneously the up and down novel folding foot rest of current and vehicle transport demand of people.
The utility model is that the technical scheme that achieves the above object is: a kind of novel folding foot rest, it is characterized in that: comprise pedal assembly, two bearings and two side plates, described pedal assembly comprises foot rest, be fixed on the cursor slide of foot rest both sides and be fixed on limited post on each cursor slide, cursor slide is provided with long slot bore, long slot bore on its tread of foot rest after opening and cursor slide parallel with horizontal plane has a down dip, and the slanted angle between the tread of long slot bore center line and foot rest is between 5～70 °; Described bearing is provided with the bearing surface and the installing hole that is positioned at bearing surface top for the supporting cursor slide, each side plate is connected on separately the bearing, the swivel pin that is connected on side plate and the bearing is arranged in the long slot bore of cursor slide, and bearing top has limited post is carried out spacing block.
The utility model improves the traditional pin pedal, Foldable pedal comprises pedal assembly and is connected to two bearings and the side plate of pedal assembly both sides, assemble simple and easy, be convenient to maintenance, because the cursor slide of pedal both sides is arranged between side plate and the bearing, cursor slide can be overturn between side plate and bearing, when making earth moving plant be in state commonly used, pedal is put down for step; When being in travel position or the passage requirement is arranged, pedal is packed up to satisfy the passage requirement, can satisfy simultaneously the people current reasonable with the vehicle borne demand structure up and down.The utility model is in the pedal assembly upset, the cursor slide of both sides can rotate along the swivel pin that is installed on bearing and the side plate, open or pack up, use light flexibly, especially the foot rest after opening is when horizontal level, the long slot bore center line of its both sides cursor slide has a down dip, and therefore can reduce the tread of first order foot rest and the height A on ground, can take full advantage of the space.The utility model can be by the long slot bore on the cursor slide, be after the axle center rotates up vertical position along swivel pin at pedal assembly, pedal assembly is moved up and down between side plate and bearing, limit shaft on the cursor slide and the limited block on bearing top are joined, can prevent from skidding off because strenuous vibration causes pedal, safe and reliable, adjustable is strong, and reduces manufacture difficulty.
