AI Technical Summary
In areas with large temperature differences, existing overhead crane tracks are prone to local bending or joint damage due to insufficient expansion joint compensation, which affects the stability of crane operation and wheel life.
The crane uses a telescopic and adjustable rail joint. Through the design of the opposing convex rail joints and clamps, the rail can be telescopically adjusted by using long holes and round holes with fastening bolts, providing a telescopic range of 40mm to adapt to temperature changes.
It effectively eliminates localized bending of the track caused by thermal expansion and contraction, ensuring smooth operation of the overhead crane, extending the service life of the wheels, and improving the stability of the track joints.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the heavy rail technology field of crown block, concretely relates to a telescopic adjustment crown block rail joint. BACKGROUND
[0002] The crown block rail generally adopts QU120 or QU100 rail, and the single rail is 12m long, and the crown block rail is connected together by manual welding or aluminum heat welding mode, and the traditional crown block rail joint is mainly in the form of reserving a gap in the crown block rail and not welding, which is used as the rail expansion joint.
[0003] At present, the crown block is used frequently in the factory, and in the area where the temperature changes greatly in the season conversion, the crown block rail is prone to expand or contract sharply, when expanding, the rail expansion joint is not enough in the reserved allowance, the two sides of the rail are pressed together, and the local rail is bent. When the rail contracts, the rail expansion joint is pulled open, the joint gap is enlarged, and under the long-term rolling of the crown block, the rail joint is crushed or the crown block wheel is blocked, and other vicious accidents occur. CONTENT OF THE UTILITY MODEL
[0004] The utility model provides a telescopic adjustment crown block rail joint to solve the problem of insufficient expansion joint compensation of the crown block rail joint when the temperature difference is large.
[0005] The utility model discloses a telescopic adjustment crown block rail joint, which comprises two convex rail joints, the two convex rail joints are oppositely arranged, the two convex rail joints are respectively provided with clamping plates on the two sides, a long hole and a round hole are arranged on the clamping plate, the long hole of one side clamping plate is opposite to the round hole of the other side clamping plate, and a fastening bolt is arranged through the opposite long hole and round hole and the convex rail joint.
[0006] As a further improvement of the utility model, a gap is left between the two convex rail joints.
[0007] The utility model has the advantages that the telescopic adjustment crown block rail joint is realized by the two opposite convex rail joints under the action of the round hole and the long hole of the two clamping plates, the influence of the local bending of the rail or the crushing of the rail joint caused by the thermal expansion and cold contraction of the rail is eliminated, the structure is simple, the installation is stable, the contraction range of the adjusted crown block rail joint can reach 40mm, the local bending of the rail can be effectively avoided, the stable operation of the crown block is ensured, and the service life of the crown block wheel is prolonged. DRAWING EXPLANATION

[0009] Figure 2The utility model discloses a top view of the utility model.
[0010] Figure 3 The utility model discloses a structure diagram of the utility model clamping plate.
[0011] In the figure: 1 - convex track joint, 2 - long hole, 3 - round hole, 4 - clamping plate, 5 - fastening bolt. DETAILED DESCRIPTION
[0012] The utility model will be further explained in detail in connection with the drawings and specific embodiment.
[0013] As Figures 1-2 The utility model discloses a telescopic adjustment's headstock track joint, including two convex track joints 1.
[0014] The utility model discloses a telescopic adjustment's headstock track joint, two convex track joints 1 are opposite and set up, and two convex track joints 1 both sides are equipped with clamping plate 4 respectively, and one long hole 2 and a round hole 3 are equipped on clamping plate 4, and the long hole 2 of one side clamping plate 4 is opposite with the round hole 3 of the other side clamping plate 4, and is equipped with fastening bolt 5 through the long hole 2 and the round hole 3 and convex track joint 1 opposite.
[0015] Two convex track joints 1 are left with the gap.
[0016] When installing headstock track, the headstock convex track joint 1 of two sides is placed opposite, makes two convex track joints 1 and leave about 40mm's interval, and the short side of convex track joint 1 is connected with the long side of another convex track joint 1 through clamping plate 4, after being connected through clamping plate 4 on the both sides of convex track joint 1, is fixed through bolt 5, and the width of the slot of the slotted clamping plate is 50mm, in the area that seasonal conversion temperature changes greatly, along with the expansion and contraction of track joint, the telescopic amount can reach 40mm, guarantees the stable operation of headstock, effectively protects headstock wheel, prolongs the service life of headstock wheel.
