Abstract
The utility model discloses a crane counter weight switching system which is characterized by comprising a winding drum, wherein a pulling steel wire rope is wound on the winding drum; both ends of the winding drum are respectively provided with winding drum flanges, the winding drum flanges are provided with rotating shafts, each rotating shaft is provided with a transmission gear, and the rotating shafts positioned between the transmission gears and the winding drum flanges are provided with inertia wheels; the transmission gears are internally provided with switching devices by which a counter weight system and the winding drum can be connected to realize transmission; the winding drum flanges are provided with outer brake wheels, the outer sides of the outer brake wheels are provided with brake pads by which the winding drum can stop rotating, the brake pads are arranged on arc-shaped support sheets, and each arc-shaped support sheet is connected with a driving base through a buffer device. The crane counter weight switching system provided by the utility model aims to overcom the defects in the prior art and is simple in structure.
Description
Technical field
The utility model relates to a kind of crane counterweight converting system.
Background technology
Existing its structure of crane counterweight converting system is relatively complicated, use inconvenient, so that existing crane counterweight converting system awaits is further perfect.
Utility model content
The purpose of this utility model is in order to overcome weak point of the prior art, and a kind of crane counterweight converting system simple in structure is provided.
In order to achieve the above object, the utility model adopts following scheme:
A kind of crane counterweight converting system, it is characterized in that: include reel, on described reel, be wound with tractive steel rope, on described reel two ends, be respectively equipped with reel flange, on described reel flange, be provided with rotating shaft, in described rotating shaft, be provided with transmission gear, in the rotating shaft between described transmission gear and reel flange, be provided with inertia wheel, in described transmission gear, be provided with and can make Weighting system engage the transfer device of transmission with reel, the wheel of stopping outside being provided with on described reel flange, on the described outer wheel outside of stopping, be provided with the brake rubber block that can make described reel stop operating, described brake rubber block is arranged on arc supporting blade, described arc supporting blade is connected to and is driven on seat by shock absorber.
A kind of crane counterweight converting system as above, is characterized in that on described brake wheel, being provided with ring-shaped brake groove, and described brake rubber block is arranged in ring-shaped brake groove.
A kind of crane counterweight converting system as above, is characterized in that described shock absorber is recoil spring.
In sum, the utility model with respect to its beneficial effect of prior art is:
The utility model is simple in structure, can when hoisting crane uplink and downlink, freely switch.When promoting, reel engages with transfer device, thereby the axle drive shaft on transfer device is rotated together with reel, thereby mentions; When loweing, reel is separated with transfer device, and the axle drive shaft idle running of Weighting system declines under the effect of self gravitation, inertia wheel and brake gear, and now, engine installation is without additional energy source consumption.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the utility model is further described:
A kind of crane counterweight converting system as shown in Figure 1, include reel 1, on described reel 1, be wound with tractive steel rope 2, on described reel 1 two ends, be respectively equipped with reel flange 3, on described reel flange 3, be provided with rotating shaft 4, in described rotating shaft 4, be provided with transmission gear 5, in the rotating shaft 4 between described transmission gear 5 and reel flange 3, be provided with inertia wheel 6, in described transmission gear 5, be provided with and can make Weighting system engage the transfer device 7 of transmission with reel 1, outside being provided with on described reel flange 3, stop and take turns 8, on described outer wheel 8 outsides of stopping, be provided with the brake rubber block 9 that can make described reel 1 stop operating, described brake rubber block 9 is arranged on arc supporting blade 10, described arc supporting blade 10 is connected to and is driven on seat 12 by shock absorber 11.
In the utility model, be to be provided with ring-shaped brake groove 13 on described brake wheel 8, described brake rubber block 9 is arranged in ring-shaped brake groove 13.Brake rubber block 9 is arranged on ring-shaped brake groove 13, effectively reduces brake rubber block 9 in brake process and rocks, and has guaranteed the service life of brake rubber block 9.
Shock absorber 11 described in the utility model is recoil spring.By recoil spring, make in brake process spring contact between brake rubber block 9 and brake wheel, effectively reduce the wearing and tearing of brake rubber block 9.
The utility model is simple in structure, can when hoisting crane uplink and downlink, freely switch.When promoting, reel engages with transfer device, thereby the axle drive shaft on transfer device is rotated together with reel, thereby mentions; When loweing, reel is separated with transfer device, and the axle drive shaft idle running of Weighting system declines under the effect of self gravitation, inertia wheel and brake gear, and now, engine installation is without additional energy source consumption.
More than show and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
