Abstract
The utility model relates to the field of the transportation of cranes, in particular to top-inserting oblique-intercepting type crane track joints which are characterized in that the track joints are in the composite form of straight connection and oblique connection, parts below a boundary are in the straight connection form, parts above the boundary are in the oblique connection form, the distance h of the boundary away from the bottom edges of tracks is correlated with the size of the height H of the tracks, and the h is not less than H/10 and not more than H/3. The oblique connection angle of the oblique connection form is alpha, and the alpha is not less than 30 degrees and not more than 70 degrees. The oblique connection angle of the oblique connection form is the alpha, and the alpha is not less than 40 degrees and not more than 50 degrees. The oblique connection angle is preferably the alpha which is equal to 45 degrees. A clearance of 3 to 7mm is remained between the joints when the tracks are connected. The utility model has the following advantages that: (1) the conditions that the tracks move and wheels contact with wheel rims are avoided by utilizing the advantages of no vibration and no movement of the wheels running on tracks with straight-connection joints and tracks with oblique-connection joints; (2) the installation is simple, quick and convenient, and the maintenance is not needed; and (3) the service life of crane tracks is prolonged, and the maintenance cost of equipment is lowered.
Description
Technical field
The utility model relates to the crane transport field, relates in particular to a kind of tip cutting slope-intercept form crane runway joint.
Background technology
In " national building standard design ", the crane runway joint has " straight joint ", " mitre joint ", " welded joint " three kinds of connection modes, and " straight joint " form is in long-term use, and recessed phenomenon appears in joint easily, and the crane operational shock is big; " mitre joint " form crane operation friction, but can't hold out against mutually between the track, the track play is maximum problem, and track one end behind the play is prone to and ejects transversion malposition, car is through the out-of-date wheel edge of gnawing, excessive clearance then appears in the other end, crane impassabitity when serious, and the joint plate bolt is broken, for fear of the track play, generally take to prevent the measure of track play during installation, but effect is also bad in actual use, maintenance is also very big; The track of " welded joint " form in use, the life-span is no more than 1 year at most, joint weldering meat cracking is subjected to the restriction of condition and welding process, can't repair, and safeguards very trouble.
Summary of the invention
The utility model provides a kind of tip cutting slope-intercept form crane runway joint at the deficiencies in the prior art, and is easy for installation, solves the current track joint and recessed, transversion malposition and the big problem of crane traveling vibration occur, prolongs the crane runway overhaul period.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of tip cutting slope-intercept form crane runway joint is characterized in that, this rail joint is the complex form of direct and mitered, the demarcation line is following to be direct form, and the demarcation line is above to be the mitered form, and the demarcation line is apart from track base distance h, with orbit altitude H dimension relationship, H/10≤h≤H/3.
The miter angles of described mitered form is α, 30 °≤α≤70 °.
The miter angles of described mitered form is α, 40 °≤α≤50 °.
Described miter angles is preferably α=45 °.
When connecting, described track leaves 3～7mm gap between joint.
Compared with prior art, the beneficial effects of the utility model are: 1, utilize wheel to move the friction advantage on the mitre joint track, can reduce vibrating noise effectively; 2, utilize the mutual mutual energy of straight joint track to withstand, the advantage of play not in is among a small circle avoided the track play, and wheel is gnawed the wheel edge, improves the serviceability rate of equipment; 3, installation is simple and direct, convenient; 4, realize the non-maintaining of crane runway joint; 5, prolong the service life of crane runway, reduce the maintenance of equipment cost.
Description of drawings
Fig. 1 is the utility model rail joint structural representation;
Fig. 2 is the birds-eye view of Fig. 1;
Structural representation when Fig. 3 is the connection of the utility model track.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, a kind of tip cutting slope-intercept form crane runway joint, this rail joint are the complex form of direct and mitered, and the demarcation line is following to be direct form, the demarcation line is above to be the mitered form, the demarcation line is apart from track base distance h, with orbit altitude H dimension relationship, H/10≤h≤H/3, as the 275T crane runway, H=120mm, h=35mm, miter angles is α=45 °.
The utility model is very suitable for one and strides many crane situations, does not need the track joint plate this moment fully; The utility model also can be used for striding the situation of single crane.Track only need withstand on two groups of tracks together when installing, and controlled span and squareness well, left 3～7mm gap, and apart from an a pair of pressing plate of 80mm position of sound production, all the other pressing plates can get final product by design arrangement, also can connect with joint plate as required in each joint.
Facts have proved that the utility model installation is simple and direct, convenient, the advantage with " straight joint " and " mitre joint " can realize the non-maintaining of crane runway joint, prolongs the service life of crane runway greatly, reduces the maintenance of equipment cost.
