Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The present invention will be further explained with reference to the drawings and specific embodiments.

As shown in figures 1-2, the conveyor heavy hammer tensioning and vibration damping device comprises an upper cover 1 and a lower cover 8, fixing rings 11 are welded on the inner sides of the upper cover 1 and the lower cover 8, and a rebound prevention device 9 penetrates through the fixing rings 11 to connect the upper cover 1 and the lower cover 8, so that the rebound and flying of the upper cover 1 are effectively prevented. Prevent resilient mounting 9 and break out including hoist and mount rope and D shape, the hoist and mount rope passes and packs into D shape behind the solid fixed ring 11 and break out and lock in breaking out, when the length of hoist and mount rope should guarantee that the taut gentle device that shakes of conveyer weight is rebounded after the pressurized, upper cover 1 can not pop out and follow required length on the lower cover 8, break away from this device after avoiding 1 rebounds of upper cover, cause each part of this device to break away from predetermined operating position, the condition that the part damaged takes place, the below of lower cover 8 is provided with rubber slab 10. The taut slow vibration device of conveyer weight is installed on floor 13 of unsettled weight straining device below in the transfer station, when emergency such as conveyer belt broken string takes place, it drops suddenly and smashes on the taut slow vibration device of conveyer weight to draw the device, apply instantaneous pressure to the taut slow vibration device of conveyer weight, the taut slow vibration device of conveyer weight alleviates the pressure of applying floor 13 through rubber slab 10, the taut slow vibration device of conveyer weight can receive reaction force to rebound with the device of drawing that hangs down simultaneously, owing to prevent that resilient mounting 9 passes solid fixed ring 11 and connects upper cover 1 and lower cover 8 as a whole, avoid upper cover 1 and lower cover 8 to separate.

Solid fixed ring 11 adopts the round steel to bend and forms, guarantees solid fixed ring 11 toughness and plasticity, and 1 side of upper cover adopts movable curb plate, uses the fastener to install in the equipment later stage and seals, can form enclosed construction all around, has effectively avoided inside debris such as dust entering device, because the atress is by the principle of line to face, and the inboard vertical welding of upper cover 1 has reinforcing plate 7, and 8 inboard horizontal welding of lower cover have reinforcing plate 7.

The reinforcing plate 7 on the lower cover 8 is welded with a plurality of positioning pipes 3. The spring 2 is freely placed in the positioning tube 3, vertical compression is realized when the spring 2 is stressed, obvious transverse shearing force is avoided, and the spring is prevented from moving and then is separated from the positioning tube 3. The size of the diameter of the spring 2 after being pressed and deformed is required to be calculated by selecting the size of the positioning tube 3, the spring 2 is in a rectangular array layout, the arrangement number of the spring 2 is required to be calculated and set according to the actual working condition, and the number of the spring 2 is not less than 4. The reinforcing plate 7 on the inner side of the upper cover 1 and the upper cover 1 is transmitted to the spring 2 by the pressure of the vertical pulling device, the spring 2 is compressed by the downward pressure and generates upward elastic force, the impact force generated when the vertical pulling device falls is greatly offset, the contact time is longer, the energy absorption effect is better, the impact of the vertical pulling device on the floor 13 is reduced, and the effective protection effect is achieved. When the spring 2 generates upward elastic force, the rebound-proof device 9 prevents the upper cover 1 from being bounced off by the elastic force of the spring 2.
