Abstract
The utility model discloses a kind of loader clamp protector, comprise lower crown (1), wearing plate (2), protected apron (3) and caliper (4), lower crown (1) is fixed on caliper (4) front end, protected apron (3) and caliper (4) are fitted and are assembled, described wearing plate (2) and lower crown (1) contact surface are each other embossed card slot fit, and it is fixing by the cooperation entirety of counter sink and securing member, compared with existing equipment, this loader clamp protector, while strengthening the abrasion resistance of clamp, wearing plate is coordinated with lower crown by concavo-convex draw-in groove, the effective shearing force that contact surface therebetween produces due to relative play when having cushioned clamping material, thus avoid set bolt fracture failure, wearing plate and protected apron are made by high-strength abrasion-proof polyurethane, and such material is applicable to the clamping that wall thickness is not more than the sheet steel pipe of 1mm and the steel pipe with heat insulating material, ensure that steel pipe under special operation condition is from wearing and tearing.
Description
Technical field
The utility model relates to a kind of protector, specifically a kind of loader clamp protector.。
Background technology
Along with loader increasing market is ripe; the performance requirement of many operating modes to loader work implements is more and more higher, except abrasion resistance, it is also proposed new requirement to the material protection under special operation condition; clamp as one of the vitals of loader, equally at the row of above performance requirement.
Traditional clamp wear-resistant device increases weldering wear-resisting steel plate at lower clamp leading portion, or be fixedly connected with organic thing wearing plate with bolt, although such way can play good wear-resisting effect, but the two all exists intrinsic defect: be easy to change though increase weldering wear-resisting steel plate, sheet steel pipe and the special operation condition such as steel pipe with heat insulating material can not be applicable to; Adopt organic friction plate to be applicable to common steel tube and be applicable to again clamping sheet steel pipe and the special operation condition such as steel pipe with heat insulating material simultaneously, but because it is bolted, during clamping steel pipe organic friction plate with have larger relative play between caliper, therefore connecting bolt is because bearing the easy fracture failure of larger transverse shearing force, thus affects loader and normally work.
Summary of the invention
The utility model provides a kind of loader clamp protector, can ensure the reliability that the abrasion resistance of clamp and wearing plate are connected with caliper, and reaches and be welded in sheet steel pipe and the applicability with the special operation condition on the steel pipe of heat insulating material for adding.
For achieving the above object, this loader clamp protector, comprise lower crown, wearing plate, protected apron and caliper, lower crown is fixed on caliper front end, protected apron and caliper are fitted and are assembled, described wearing plate and lower crown contact surface are each other embossed card slot fit, and fixing by the cooperation entirety of counter sink and securing member.
The material of wearing plate and protected apron is high-strength abrasion-proof polyurethane.
Concavo-convex draw-in groove is multiple, and is distributed on wearing plate and the mutual contact surface of lower crown.
Compared with existing equipment, this loader clamp protector, while the abrasion resistance strengthening clamp, wearing plate is coordinated with lower crown by concavo-convex draw-in groove, the effective shearing force that contact surface therebetween produces due to relative play when having cushioned clamping material, thus avoid set bolt fracture failure; Wearing plate and protected apron are made by high-strength abrasion-proof polyurethane, and such material is applicable to the clamping that wall thickness is not more than the sheet steel pipe of 1mm and the steel pipe with heat insulating material, ensure that steel pipe under special operation condition is from wearing and tearing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, this loader clamp protector, comprises lower crown 1, wearing plate 2, protected apron 3 and caliper 4, and lower crown 1 is fixed by welding in caliper 4 front end, and protected apron 3 has counter sink, during assembling and caliper 4 radian fit completely, and pass through bolt
5 and packing ring
6 are fixedly connected with; Described wearing plate 2 and lower crown 1 contact surface are each other embossed card slot fit, and by opening counter sink on wearing plate 2 and bolt
7 and packing ring
the cooperation entirety of 8 is fixing, the shearing force that effectively during buffering clamping material, wearing plate 2 produces with relative play between lower crown 1, thus avoids set bolt
7 fracture failures.
The material of wearing plate 2 and protected apron 3 is high-strength abrasion-proof polyurethane, can ensure wear-resisting while protection wall thickness be not more than 1mm sheet steel pipe and with the steel pipe of heat insulating material from wearing and tearing.
Concavo-convex draw-in groove for can establish two and more than, offer multiple, and be distributed on wearing plate 2 and the mutual contact surface of lower crown 1, the two can be made better to block, stressed evenly, thus the shearing force that between more effective buffering wearing plate 2 with lower crown 1, relative play produces.
Claims (3)
1. a loader clamp protector, comprise lower crown (1), wearing plate (2), protected apron (3) and caliper (4), lower crown (1) is fixed on caliper (4) front end, protected apron (3) and caliper (4) are fitted and are assembled, it is characterized in that, described wearing plate (2) and lower crown (1) contact surface are each other embossed card slot fit, and fixing by the cooperation entirety of counter sink and securing member.
