Description

Technical Field

[0001] The utility model belongs to the technical field of track fixing, and in particular relates to a track clamp used for installing and fixing industrial tracks. Background Art

[0002] The rail clamp is also called a welded rail clamp, a welded rail fixing device, a steel beam rail clamp, and a welded pressure plate. Its function is to clamp and fix the rail. At present, the rail clamp used for industrial track installation is generally a combination of a base, an upper cover plate, an adjustment plate, and bolts. The track is placed on the track beam, and the base is welded to the steel beams on both sides of the track. Bolts, adjustment plates, and upper covers are placed on the base. The adjustment plate adjusts the distance between the upper cover plate and the edge of the track so that the upper cover plate can press and tighten the track, and then tighten the bolts so that the rail clamp as a whole clamps the track. However, the lateral force bearing point of the rail clamp (the raised part behind the base) is relatively thin. When the lateral force is large, the base and bolts are broken, causing damage to the base, and the upper cover plate loosens and falls off the track backward, posing a safety hazard; and after long-term use of lifting and transportation equipment, the vibration bolts of the track are easy to loosen, causing the rail clamp to loosen.

[0003] Therefore, the traditional rail clamp has a great potential safety hazard during use. Utility Model Content

[0018] In order to better understand the present invention, the contents of the present invention are further explained below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0019] In one embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the utility model provides a rail clamp for installing and fixing industrial rails, which mainly includes: a base 100, an upper cover plate 200, and a bucket-shaped bolt 300; the base 100 is fixed on the track beam, the upper cover plate 200 covers the base 100, and a wedge-shaped bite mechanism 400 sliding along the lateral direction is provided at the overlapping edge of the upper cover plate 200 and the base 100; a through hole 210 is provided on the upper cover plate 200, and an open hole groove 110 is provided on the base 100 at a position corresponding to the through hole 210; the bucket-shaped bolt 300 passes through the through hole 210 and the open hole groove 110 to lock the upper cover plate 200 and the base 100.

[0020] Among them, the base 100 can be welded and fixed on both sides of the track on the track beam, the bucket-shaped bolts 300 can be placed in the base 100, and after closing the upper cover plate 200, the sliding upper cover plate 200 can adjust the distance between it and the track, so that the upper cover plate 200 and the track contact surface are tightly pressed, and then the bucket-shaped bolts 300 are tightened.

[0021] A wedge-shaped bite mechanism 400 that slides in the lateral direction is also provided at the edge where the upper cover plate 200 and the base 100 overlap. The wedge-shaped bite mechanism 400 can prevent the fixed base 100 and the upper cover plate 200 from retreating and can be automatically locked, forming a locking component with dual lateral force bearing points.

[0022] In this embodiment, a wedge-shaped engaging mechanism 400 that slides in the lateral direction is provided at the overlapped edge of the upper cover plate 200 and the base 100, so that the fixed base 100 and the upper cover plate 200 can be prevented from retreating and can be automatically locked, and a locking component with double lateral force bearing points is provided; the design that the front end of the base 100 and the upper part of the base 100 are subjected to force at the same time makes the lateral force of the track transmitted by the upper cover plate 200 act on the entire base, thereby preventing the damage to the track clamp by a large lateral force; the design of the wedge-shaped engaging mechanism 400 reduces the loosening of the bolts, making the maintenance of the track more convenient; the bucket-shaped bolts 300 are not easy to break, have a long service life, and are highly safe.

[0023] In one embodiment, Figure 1 As shown, arc-shaped reinforcing ribs 202 are respectively provided on the edges of both sides of the upper cover plate 200 .

[0030] The utility model provides a method for using a rail clamp for installing and fixing an industrial rail as follows:

[0031] The rail clamp base is welded and fixed to both sides of the rail on the rail beam;

[0032] Put the bucket bolts into the base, close the upper cover, slide the upper cover to adjust the distance from the track, and make the contact surface between the upper cover and the track tight and compact;

[0033] Tighten the bucket bolts.

[0034] A rail clamp for fixing and installing industrial rails provided in this embodiment comprises a base, an upper cover plate and bucket-shaped bolts. The upper cover plate is covered on the base, and the base is welded and fixed on the rail beam. A wedge-shaped interlocking mechanism that slides in the lateral direction is designed between the base and the upper cover plate, so that the fixed base and the upper cover plate can be prevented from retreating and can be automatically locked, and has a locking component with dual lateral force bearing points; and a bucket-shaped bolt structure that fastens the upper cover plate and the base, and the entry position of the bolts on the base is designed as an open hole to reduce the phenomenon of rusting of the bolts due to water accumulation in the bolt holes. The design that the front end and the upper part of the base are subjected to force at the same time allows the lateral force of the rail transmitted by the upper cover plate to act on the entire base, thereby preventing the damage to the rail clamp by large lateral forces. The wedge-shaped interlocking mechanism design reduces the phenomenon of bolt loosening, making the maintenance of the rails more convenient.

[0035] A rail clamp for installing and fixing industrial tracks provided in this embodiment can simplify track construction and installation, and can solve problems such as breakage of the rail clamp base and bolts, loosening and falling off of the upper cover, and track displacement caused by the huge lateral force transmitted to the track by the lifting and transportation equipment during use.
