Detailed implementation manners
[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a large cylinder body transfer device, including two groups of steel rails 1 vertically and crosswise arranged on the foundation and a trolley 2 that can travel on the steel rails 1; there are two trolleys 2, and each trolley 2 is equipped with a support plate 3 with an arc groove 31 for supporting the lower end of the cylinder body 6 to be transferred; it also includes a hydraulic pump station 4 arranged near the intersection of the two groups of steel rails 1. The hydraulic pump station 4 is provided with a high-pressure hose 41, and the end of the high-pressure hose 41 is detachably connected to a lifting cylinder 42 fixed on the foundation at the intersection; the lifting cylinder 42 is used to lift the trolley 2 traveling to the intersection; the lower end of the support plate 3 is provided with a rotating shaft 32, and the rotating shaft 32 is rotatably inserted into a preset shaft hole 21 on the trolley 2 for the support plate 3 to rotate; the lower end of the trolley 2 is connected to four traveling wheel assemblies 5, and each traveling wheel assembly 5 includes a wheel carrier 51, a wheel axle 52, and a wheel 53; the wheel axle 52 is inserted into the center of the wheel 53, and both ends thereof are rotatably connected to the lower end of the wheel carrier 51; the upper end of the wheel carrier 51 is fixedly connected with a pin shaft 54; the pin shaft 54 is inserted into a preset jack hole 22 on the trolley 2; on the upper surface of the trolley 2, corresponding to each jack hole 22 position, there is a square box 23 facing the axis of the jack hole 22, and through positioning holes 24 are respectively opened on the front, rear, left, and right side walls of the square box 23; a pin hole 55 corresponding to the positioning hole 24 is opened on the upper part of the pin shaft 54, and a plug pin 56 is inserted into the positioning hole 24 and the pin hole 55 to fix the pin shaft 54.
[0022] The working principle is as follows. This device includes two parts: a fixing mechanism and a moving mechanism. The fixing mechanism includes two sets of crossed steel rails 1, a hydraulic pump station 4, and a lifting cylinder 42. The moving mechanism consists of two trolleys 2. The cylinder body 6 is loaded onto the two trolleys 2 and is transferred by walking along the steel rails 1. When one of the front trolleys 2 walks to the crossing, it stops, connects the high-pressure hose 41 to the lifting cylinder 42, and the hydraulic pump station 4 supplies oil. The trolley 2 is slightly lifted by the lifting cylinder 42 so that the four wheels 53 are disengaged from the steel rails 1. Then, the pin 56 of one of the traveling wheel assemblies 5 is pulled out to release the locking of the pin shaft 54, and the pin shaft 54 is rotated until the wheel 53 rotates by 90 degrees to coincide with the traveling direction of the other set of steel rails 1. Then, the pin 56 is inserted into the pin hole 55 and the positioning hole 24 to lock the traveling wheel. Repeat the above steps to rotate each traveling wheel assembly 5 by 90 degrees one by one to complete the commutation. Then, the hydraulic pump station 4 unloads the oil, the lifting cylinder 42 retracts, the trolley 2 drops, and the high-pressure hose is removed from the lifting cylinder 42 to prevent the high-pressure hose from being dragged when the trolley 2 walks. The trolley 2 walks along the steel rails 1 after turning, and the other trolley 2 continues to walk along the original steel rails 1. As Figure 4 shown, the cylinder body 6 is driven to turn until the rear trolley 2 travels to the crossing. Repeat the method to turn the four wheels 53 of this trolley 2. Then, both trolleys 2 are transferred to the same steel rail 1 and continue to walk to complete the in-situ turning of the cylinder body 6. This avoids the arc turning of the ultra-long cylinder body 6 and reduces the occupation of the site.
[0023] To facilitate the rotation of the pallet 3 on the trolley 2, a thrust bearing 33 is also included. The thrust bearing 33 is sleeved on the rotating shaft 32 and is located between the upper end of the trolley 2 and the lower end face of the pallet 3 for supporting the rotation of the pallet 3.
[0024] To drive the trolley 2 to walk, although power can be equipped on the trolley 2, it increases the cost. In this embodiment, a non-powered dragging method is used to tow the trolley 2, and a towing vehicle is used to tow the trolley 2 to walk. To facilitate towing the trolley 2, towing rings 25 are fixedly connected to the front, rear, left, and right side walls of the trolley 2.
[0025] Exemplary lifting cylinder 42. The lower end of the lifting cylinder 42 is fixedly connected to a preset base on the foundation, and its side wall is provided with an interface for detachably connecting to the high-pressure hose. The upper end of the telescopic rod of the lifting cylinder 42 is fixedly connected to a top plate 43 for supporting the lower end face of the trolley 2.
[0026] To facilitate the grasping operation of the pin shaft 54, the upper end of the square box 23 is open; a pull ring 57 is fixedly connected to the upper end of the pin shaft 54. By grasping the pull ring 57, the pin shaft 54 is driven to rotate. More preferably, the outer contour dimension of the pull ring 57 is larger than the dimension of the open end, so that when the bolt 56 is pulled out, the pull ring 57 abuts against the upper end of the square box 23 to prevent the wheel carrier 51 from separating from the trolley 2. At this time, the pull ring 57 becomes a limiting component, ensuring that the traveling wheel assembly 5 is always not separated from the trolley 2, which is convenient for operation.
[0027] The advantages of the present utility model are as follows.
[0028] (1) It can make the large cylinder body 6 turn in place, avoiding the arc turning of the ultra-long cylinder body 6 and reducing the occupation of the site.
[0029] (2) The moving mechanism and the fixing mechanism of the present device are separately arranged, and there is no power source on the trolley 2, with a simple structure and low cost.
[0030] (3) The present device does not lift the trolley 2 significantly. Only a slight lift is required to complete the reversal of the wheels 53, reducing the deformation of the cylinder body 6 and avoiding the cylinder body 6 falling off the trolley 2 during the reversal, thus improving safety.
[0031] In summary, in this embodiment, the cylinder body 6 is transported on two sets of vertically intersecting steel rails 1, allowing the cylinder body 6 to turn in place and improving the safety during the transportation process.
[0032] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
