Description

Technical Field

[0001] The utility model relates to the technical field of crankshaft hangers, in particular to a crankshaft vertical hanging tool. Background Art

[0002] The crankshaft is the most important part of the engine. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsion loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work evenly and have good balance.

[0003] The existing crankshaft vertical lifting tooling generally fixes one end of the crankshaft first and then lifts it directly. At the same time, there is a lack of protection during the transfer process. It is easy to bump into each other during the continuous lifting of multiple groups of crankshafts, which in turn affects the quality of the crankshafts. At the same time, the stability of the crankshaft fixation needs to be further improved. Therefore, we proposed a crankshaft vertical lifting tooling. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A crankshaft vertical lifting tool, comprising: a lifting cable and a lifting component; the lifting component is arranged on the lifting cable; the lifting component includes a traction mechanism connected to the lifting cable and a fixing mechanism fixed to the traction mechanism; the fixing mechanism includes a lifting box, an electric telescopic rod installed at the bottom of the side of the lifting box, an elastic rope fixed to the driving end of the electric telescopic rod, a fixing ring connected to the end of the elastic rope, a traction rope fixed to the top of the fixing ring and connected to the lifting cable, a slide rail installed in the lifting box and for the traction rope to pass through, a fixed cotton pad fixed on the slide rail and a fixed cotton block installed at the end of the lifting box.

[0013] The utility model can place the lifting box cover on the outside of the crankshaft through the lifting component. At this time, the two ends of the crankshaft are respectively located on the sides of the fixed ring and the fixed cotton block. When the lifting cable is pulled upward, the ring will be pulled on the connecting rope first, and then the fixing ring will be pulled by the pulling rope to cover one end of the crankshaft, and then the crankshaft will be pressed on the fixed cotton pad, and the other end will be inserted into the fixed cotton block.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] A crankshaft vertical lifting tool provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0022] Combination Figure 1-2 As shown, the utility model provides a crankshaft vertical lifting tool, comprising: a lifting cable 100 and a lifting assembly 200; the lifting assembly 200 is arranged on the lifting cable 100.

[0023] Among them, the hoisting assembly 200 includes a traction mechanism connected to the hoisting cable 100 and a fixing mechanism fixed to the traction mechanism 300; the fixing mechanism includes a hoisting box 210, an electric telescopic rod 220 installed at the bottom of the side of the hoisting box 210, an elastic rope 230 fixed to the driving end of the electric telescopic rod 220, a fixing ring 240 connected to the end of the elastic rope 230, a traction rope 250 fixed to the top of the fixing ring 240 and connected to the hoisting cable 100, a slide rail 260 installed in the hoisting box 210 and for the traction rope 250 to pass through, a fixed cotton pad 270 fixed on the slide rail 260 and a fixed cotton block 280 installed at the end of the hoisting box 210.

[0024] Furthermore, the traction mechanism 300 includes an adapter 310 installed at the end of the hoisting box 210, a connecting rope 320 connected to the adapter 310, a limit block 330 fixed to the end of the connecting rope 320, a ring 340 sleeved on the connecting rope 320 for connecting the traction rope 250, a side connecting rope 350 fixed to the ring 340 and passing through the limit block 330, and a connecting block 360 fixed to the end of the side connecting rope 350 and connected to the hoisting cable 100. Through the hoisting assembly 200, the hoisting box 210 cover can be placed on the outside of the crankshaft. At this time, the two ends of the crankshaft are respectively located at the fixing ring 240 and the fixing ring 240. On the cotton block 280 side, when the hoisting cable 100 is pulled upward, the ring 340 will be pulled on the connecting rope 320 first, and then the traction rope 250 will be used to pull the fixing ring 240 to cover one end of the crankshaft, and then the crankshaft will be pressed on the fixed cotton pad 270, and the other end will be inserted into the fixed cotton block 280. At this time, the crankshaft can be fixed in the lifting box 210, and the lifting cable 100 can be used for vertical lifting operations. After the lifting is completed, the handle 211 is pulled before lowering to lower the lifting box 210, and then the electric telescopic rod 220 drives the fixing ring 240 to be retracted, and the lifting box 210 can be removed. This solution not only has a better protection effect, but also is relatively simple and convenient for fixing the crankshaft, and has high stability.

[0025] Specifically, a handle 211 is provided at the end of the hoisting box 210, which can facilitate manual assistance in correcting the position of the hoisting box 210 during material unloading, thereby facilitating material unloading.

[0026] Furthermore, a guide pad 212 is provided at the bottom of the lifting box 210 and is located below the electric telescopic rod 220, and the end of the guide pad 212 is tilted toward the bottom of the fixing ring 240. The guide pad 212 can prevent the crankshaft from contacting the electric telescopic rod 220, and at the same time, one end of the crankshaft can be guided to the middle of the fixing ring 240, so that the positioning is more precise, which is convenient for subsequent first fixation.

[0027] On the other hand, guide rings 261 are provided at both ends of the slide rail 260, through which the traction rope 250 can move more smoothly, and when the traction rope 250 is pulled by force, the slide rail 260 will also move with the crankshaft in the direction of the fixed cotton block 280, which is convenient for fixation.

[0028] Furthermore, the hoisting box 210 is provided with a through hole 213 for the traction rope 250 to pass through, so that the traction rope 250 can be led out and connected to the traction mechanism 300, which is more convenient.

[0029] The working principle and use process of the utility model are as follows: first, the lifting box 210 cover is placed on the outside of the crankshaft. At this time, the two ends of the crankshaft are respectively located on the side of the fixed ring 240 and the fixed cotton block 280. When the lifting cable 100 is pulled upward, the ring 340 will be pulled on the connecting rope 320 first, and then the fixing ring 240 will be pulled by the pulling rope 250 to cover one end of the crankshaft, and then the crankshaft is pressed on the fixed cotton pad 270, and the other end is inserted into the fixed cotton block 280. At this time, the crankshaft can be fixed in the lifting box 210, and the lifting cable 100 is cooperated to perform vertical lifting operations. After the lifting is completed, the handle 211 is pulled before lowering to lower the lifting box 210, and then the electric telescopic rod 220 drives the fixing ring 240 to be retracted, and the lifting box 210 can be removed.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
