Description

Auxiliary support device for hoist drum

technical field

The utility model belongs to the technical field of mechanical support components, and in particular relates to a device for auxiliary supporting the hoisting drum of a hoist.

Background technique

The winch hoist is a hoisting device driven by electric power through a flexible member such as a wire rope to lift and transport heavy objects. It has a simple structure and is easy to use. It is widely used in coking, metallurgy, mining and other fields. Lifting operations. In general, gravity acts on the hoisting drum through the wire rope, which produces a certain torque and bending moment on the hoisting drum, especially at the moment when the hoist starts, reverses, and stops, the impact on the hoisting drum will be greater . Fig. 1 is an assembly perspective view of a hoisting drum without an auxiliary supporting device, including a hoisting drum 1, a hoisting drum left end support device 2, a hoisting drum right end support device 3 and a steel wire rope 4 installed on the hoisting drum. It can be seen from the figure that when lifting heavy objects, the higher the lifting height, the more the left and right wire ropes 4 will leave the left and right end supports 2 and 3 at the same time and approach the middle position of the hoisting drum 1, and the longer the hoisting drum is, the longer the hoisting drum will be. The closer the hoisting wire rope is to the middle position of the hoisting drum, the greater the bending moment and adverse effects on the hoisting drum 1 will be.

The hoisting drum of the CDQ hoist of our company is long in length, and the actions of starting, reversing, stopping, accelerating, and decelerating are frequent. During the use, the hoisting drum has cracks and cracks in the cylinder many times, which seriously restricts CDQ. Normal production of coke.

Contents of the invention

In order to solve the above problems, the utility model discloses an auxiliary support device for a hoist drum of a hoist, which can reduce the adverse effects of torque and bending moment acting on the hoist drum on the hoist drum.

In order to achieve the above object, the utility model provides the following technical solutions:

An auxiliary support device for a hoist drum, comprising a support rail, a base, two sets of support roller assemblies fixed on the base, and fasteners, the support rail is fixed in the middle of the hoist drum, and the two sets of support roller assemblies The support rails are respectively located on both sides below the support rails. The support roller assembly includes a bracket and a roller fixed on the top of the bracket. The four corners of the bracket are respectively provided with waist-shaped holes, and the fasteners pass through the waist-shaped holes to fix the bracket on the On the base, adjustment devices are respectively provided on both sides of each set of support roller assemblies. The adjustment devices include positioning blocks fixed on the base and supporting screws installed at both ends of the positioning blocks. The supporting screws pass through the positioning blocks. The threaded holes on the block fit against the side of the bracket.

Further, the support track is formed by connecting at least two circular arc tracks.

Further, the bracket includes a base plate and two triangular plates fixed on the base plate, and reinforcing ribs are connected between the triangular plates and the base plate.

Beneficial effect:

The utility model cooperates with the supporting track fixed at the middle part of the hoisting drum and the supporting roller assembly under the supporting rail, which can play an auxiliary supporting role for the hoisting drum, improve the dynamic and static stiffness of the hoisting drum, and resist deformation. It is not easy to be damaged by excessive bending moment and torque, and it plays a good role in protecting the hoisting drum and reduces the maintenance rate.

Detailed ways

The utility model will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the utility model and are not intended to limit the scope of the utility model. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, and Fig. 6, an auxiliary support device for hoisting drums of a hoist includes a support rail 5, a base 606, and two sets of front and rear support roller assemblies 6 fixed on the base . Fastener 607, the support rail 5 is fixed at the middle part of the hoisting drum 1, and is formed by connecting multiple circular arc rails 501 as shown in FIG. 3 . Two sets of support roller assemblies 6 are respectively located on both sides below the support rail for supporting the support rail 5. The support roller assembly 6 includes a bracket 601 and a roller 602 fixed on the top of the bracket.
