Detailed Description

The technical solutions in the implementation of the present invention will be clear from the following description and accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 5, an embodiment of the present invention provides a split-type chain type tilter, which includes a base 3, a speed reducer 1 disposed in front of the base 3, and force arms 4 disposed on left and right sides of the base 3 respectively and having the same structure, wherein a speed reducer shield 2 for protecting the speed reducer is disposed on the base 3; the force arm 4 and the base 3 are connected through bolts, an upper chain wheel 9 and a lower chain wheel 10 are respectively arranged at the top and the bottom of an inner cavity of the force arm 4, and a driving chain wheel 11 driven by the speed reducer 1 is arranged in the base 3; the closed chain 7 is wound among the driving chain wheel 11, the upper chain wheel 9 and the lower chain wheel 10, and the chain 7 between the two upper chain wheels 9 is suspended above the base 3. As shown in fig. 5, the utility model is preferably used in pairs when in specific use, and the split tilters can be used to support the front and the rear ends of the steel respectively, so as to turn over the steel integrally. Of course, one end of the steel material can be fixed on other rotatable platforms, and the other end of the steel material is supported by only one split turnover machine for turnover. The reducer shield 2 can prevent the reducer 1 from being broken by a hammer when an accident happens. The force arm 4 is in an I-shaped shape to enhance the anti-collision capacity. The upper chain wheel 9 and the lower chain wheel 10 are both arranged on the force arm 4 through a bearing seat 5.

Further, a chain bracket 8 for preventing the chain 7 from falling off the lower chain wheel 10 is arranged below the lower chain wheel 10 in the force arm 4. As shown in fig. 4, the chain holder 8 limits the distance that the chain 7 hangs down, thereby preventing the chain 7 from falling off the bottom of the lower sprocket 10 due to the natural falling of the chain 7 on the lower sprocket 10 by gravity.

Further, the chain bracket 8 is a nylon plate. The nylon plate has good wear resistance and can be used for a long time.

Further, the horizontal distance between the upper sprocket 9 and the drive sprocket 11 is smaller than the horizontal distance between the lower sprocket 10 and the drive sprocket 11. As shown in fig. 2, the upper sprocket 9 is spaced apart from the driving sprocket 11 by a smaller horizontal distance than the lower sprocket 10, so that the chain 7 between the upper sprocket 9 and the lower sprocket 10 is inclined at an angle such that the chain 7 can be wound around the lower sprocket 10 by its own weight to a greater extent, so that the chain 7 is less likely to be separated from the sprocket 10.

Further, the upper chain wheel 9, the lower chain wheel 10 and the driving chain wheel 11 are double-row chain wheels, and the chain 7 is a double-row chain matched with the double-row chain wheels. The double-row chain wheel and the double-row chain have stronger bearing capacity and can support steel with larger weight.

Furthermore, a detachable arm closing plate 6 is arranged on the part, facing the lower chain wheel 10, of the arm 4, which is far away from the base 3. As shown in fig. 1, the whole force arm 4 is in a closed state, only the upper end of the force arm 4 is provided with a chain outlet, one side of the lower end of the force arm 4 is communicated with the base 3, and the force arm sealing plate 6 arranged on one side of the lower end of the force arm 4 far away from the base 3 can be used for checking and replacing the chain bracket 8.

When in use: place steel on two chains 7 between last sprocket 9, start speed reducer 1, chain 7 begins to rotate at the sprocket circulation, when chain 7 clockwise turning, because the effect of friction force, steel moves along with chain 7 upper right side, when treating to remove to the take the altitude, because the effect of steel self gravity and friction force realizes steel to left upset, when adjusting suitable angle, closes speed reducer 1, then carries out welding process, convenience simple to use to steel.
