Description

Technical Field

[0001] The present application relates to the field of turning equipment, and in particular to a vertical hydraulic turning machine for large refrigeration equipment. Background Art

[0002] During the transportation process, the refrigeration equipment must first be transported to the bottom of the lifting device (gantry crane) by the transfer vehicle, and then hoisted into place by the lifting device. When the transfer vehicle transports the refrigeration equipment, in order to lower the center of gravity of the refrigeration equipment and improve the safety of transportation, the refrigeration equipment is usually placed in a horizontal state. After the transfer vehicle transports the refrigeration equipment to the lifting device, the refrigeration equipment is flipped from a horizontal state to a vertical state by the flipping device, and the vertical refrigeration equipment is hoisted to the designated location by the lifting device.

[0003] In the related art, patent number CN116199083A discloses a flipping device, which includes a flipping frame (connecting part) and a base (rotating part). When performing the flipping operation of the equipment, the equipment to be flipped must be fixed on the flipping frame first, and then the flipping frame must be connected to the sling and the flipping frame must be hinged on the base. Finally, the flipping frame and the equipment can be flipped by cooperating with the weight of the flipping frame and the equipment through the sling.

[0004] With regard to the above-mentioned related technologies, when flipping the equipment, the flipping device achieves the flipping of the equipment by means of a sling cooperating with the equipment and the weight of the flipping frame. The stability and reliability are poor, and it is difficult to achieve a smooth flipping of the flipping frame and the equipment. There are certain safety hazards, which causes the flipping device to be unable to meet the flipping operations of some heavy equipment. Therefore, there is room for improvement.

[0009] The two ends of the telescopic driving member are respectively connected to the base and the flip frame with horizontal rotation, and the rotation axes at the two ends of the telescopic driving member are arranged parallel to the rotation axes of the flip frame.

[0010] By adopting the above technical scheme, before flipping the refrigeration equipment, the retractable driving member is first used to drive the flip frame to swing to a horizontal state. When flipping the refrigeration equipment, the refrigeration equipment to be flipped is placed on the flip frame in a horizontal state, and then the retractable driving member is used to drive the flip frame to drive the refrigeration equipment on the flip frame to flip to a vertical state, thereby realizing the flipping operation of the refrigeration equipment; while the retractable driving member is used to extend and drive the flip frame to flip, the retractable driving member can also be used to auxiliary support the flip frame, thereby reducing the load concentration on the connection between the flip frame and the base when the refrigeration equipment and the flip frame are flipped, which causes the connection between the flip frame and the base to be easily damaged, and is beneficial to improving the stability and reliability of the flip device when flipping the refrigeration equipment.

[0011] Preferably, the flip frame includes a support frame, and one end of the support frame is vertically connected to a bracket.

[0012] By adopting the above technical solution, before flipping the refrigeration equipment, the support frame on the flip frame is driven to swing to a horizontal state by the telescopic driving member. When the support frame of the flip frame is subsequently driven by the telescopic driving member to drive the refrigeration equipment to flip, the refrigeration equipment can be supported by the bracket at the end of the support frame to limit the refrigeration equipment from being separated from the flip frame, thereby facilitating the flipping operation of the refrigeration equipment.

[0013] Preferably, the support frame is vertically connected to the limiting frames on both opposite sides.

[0014] By adopting the above technical solution and setting two sets of limit frames, it is convenient to limit the relative sides of the support frame to prevent the subsequent support frame from driving the refrigeration equipment to slide out from the relative sides of the support frame during the flipping process, so that the flipping frame can drive the refrigeration equipment to flip more stably.

[0020] By adopting the above technical solution and setting the lifting drive component, the lifting cylinder can be used to drive the flip frame to rise and fall. After the subsequent transfer vehicle transports the refrigeration equipment to the top of the support frame in a horizontal state, the lifting drive component is used to drive the flip frame support plate to move up until the support plate lifts the refrigeration equipment, so as to achieve the stable placement of the refrigeration equipment on the support frame.

[0021] Preferably, a plurality of lifting cylinders are vertically arranged on the bracket, and piston rods of the lifting cylinders extend downward to prop up the bracket.

[0022] By adopting the above technical solution, after the subsequent transfer vehicle transports the refrigeration equipment to the top of the support frame in a horizontal state, the jacking cylinder drives its own piston rod to extend to drive the base and the flip frame to move upward, until the support frame of the flip frame lifts the refrigeration equipment to be flipped, so as to achieve the stable placement of the refrigeration equipment on the support frame.

[0023] Preferably, a plurality of diagonal support rods are provided between the main support tube and the base, one end of each diagonal support rod is connected to the bracket, and the other end of each diagonal support rod is connected to the top end of the main support tube.

[0024] By adopting the above technical solution, the connection strength between the support rod and the bracket is improved by using the diagonal brace rod, which is conducive to supporting the support rod more stably on the bracket.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. While the retractable driving member drives the flip frame to flip the refrigeration equipment, the retractable driving member can be used to auxiliary support the flip frame, which is beneficial to improve the stability and reliability of the flip device, so that the flip device can better flip the heavy refrigeration equipment.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] The present application embodiment discloses a vertical hydraulic turning machine for large refrigeration equipment, referring to Figure 1 and Figure 2 , including a base 1, a flip frame 2 and a telescopic driving member 3, the flip frame 2 is horizontally rotatably connected to the base 1; the two ends of the telescopic driving member 3 are respectively horizontally rotatably connected to the flip frame 2 and the base 1, and the flip frame 2 can be driven to flip by telescoping the telescopic driving member 3.

[0036] The base 1 comprises two sets of brackets 11 arranged opposite to each other, and the brackets 11 are welded by a plurality of I-beams. Support rods 12 are fixed vertically upward on the brackets 11.

[0037] The flip frame 2 is located between the two groups of brackets 11. The flip frame 2 includes a support frame 21. A bracket 22 is vertically welded to one end of the support frame 21. A limit frame 23 is also vertically welded to the opposite sides of the support frame 21. In this embodiment, the support frame 21, the bracket 22 and the limit frame 23 are all welded by metal square tubes.

[0038] A plurality of lifting cylinders 13 are also fixed vertically downward on the bracket 11, and the piston rods of the plurality of lifting cylinders 13 extend downward to lift the bracket 11 to support the bracket 11. Through the above arrangement, after the transfer vehicle lifts the refrigeration equipment to be flipped to the top of the support frame 21 in a horizontal state, the lifting cylinders 13 drive the respective piston rods to extend downward to lift the two groups of brackets 11 and the flip frame 2 off the ground until the support frame 21 on the flip frame 2 supports the bottom of the refrigeration equipment to be flipped, which is conducive to smoothly transferring the refrigeration equipment to the support frame 21. At the same time, the lifting cylinders 13 drive the flip frame 2 to move upward, which is conducive to reducing the interference between the flip frame 2 and the ground when the subsequent telescopic drive member 3 drives the flip frame 2.

[0039] Reference Figure 1 and Figure 3 , a main connection seat 4 is fixed on the top of the support rod 12; a secondary connection seat 5 is fixed on the side of the limiting frame 23 away from the support frame 21, and the secondary connection seats 5 on the two groups of limiting frames 23 correspond to the main connection seats 4 on the two groups of support rods 12 one by one, and a pin shaft 6 is arranged between the corresponding main connection seats 4 and the secondary connection seats 5, and both ends of the pin shaft 6 are respectively rotatably penetrated through the main connection seat 4 and the secondary connection seat 5 through bearings, so as to realize the rotatable connection of the flip frame 2 to the two groups of brackets 11. The setting of the bearing is convenient for reducing the wear of the main connection seat 4 and the secondary connection seat 5 on the pin shaft 6, which is conducive to improving the durability of the pin shaft 6. The tail end of the pin shaft 6 is also threadedly connected with an anti-drop nut, which is conducive to reducing the situation where the pin shaft 6 falls off during the subsequent rotation of the flip frame 2.

[0040] In this embodiment, the telescopic drive member 3 is a multi-stage hydraulic cylinder, and the multi-stage hydraulic cylinder stroke is sufficient to flip the flip frame 2 from a vertical state to a horizontal state. Two groups of telescopic drive members 3 are provided, and the two groups of telescopic drive members 3 are respectively located on two groups of brackets 11. One end of the telescopic drive member 3 is horizontally rotatably connected to the bottom end of the support rod 12, and the other end of the telescopic drive member 3 is horizontally rotatably connected to one end of the limit frame 23 close to the support frame 21. The rotation axes at both ends of the telescopic drive member 3 are arranged parallel to the rotation axis of the flip frame 2.

[0041] Through the above arrangement, when the refrigeration equipment is turned over, the two sets of telescopic driving members 3 are used to drive the support frame 21 of the turning frame 2 to swing to a horizontal state. After the refrigeration equipment to be turned over is placed on the support frame 21, the turning device is first lifted to a certain height by a plurality of lifting cylinders 13 to ensure that the support frame 21 can turn over normally, thereby reducing the interference between the turning frame 2 and the ground when the telescopic driving members 3 drive the turning frame 2. Then, the two sets of telescopic driving members 3 are used to drive the support frame 21 of the turning bracket 11 to drive the refrigeration equipment to swing to a vertical state. During the turning process of the support frame 21, the bracket 22 at the end of the support frame 21 is used to lift the refrigeration equipment to prevent the refrigeration equipment from sliding off the end of the support frame 21 during the turning process of the support frame 21. At the same time, the limit frames 23 on both sides of the support frame 21 perform auxiliary limit on the refrigeration equipment of the support frame 21 to prevent the refrigeration equipment from sliding out from both sides of the support frame 21 during the turning process, so that the turning frame 2 can drive the refrigeration equipment to turn over more smoothly.

[0042] When the telescopic driving member 3 drives the bracket 22 on the flip frame 2 to swing to a horizontal state, the bracket 22 is located between the two groups of brackets 11. On the one hand, it is conducive to improving the compactness of the flip device, and on the other hand, it is convenient for the subsequent telescopic driving member 3 to drive the flip frame 2 to swing the refrigeration device to a vertical state, so that the center of gravity of the flip frame 2 and the refrigeration device can be located above the two groups of brackets 11, which is conducive to maintaining the overall center of gravity balance of the flip device.

[0043] Reference Figure 1 and Figure 3 The support rod 12 includes a main support tube 121, which is vertically welded to the bracket 11. A secondary support tube 122 is slidably inserted into the top of the main support tube 121. In this embodiment, the main support tube 121 and the secondary support tube 122 are both metal square tubes.

[0044] The main connecting seat 4 is fixed to the top of the secondary support tube 122. A lifting drive 15 is also vertically arranged in the main support tube 121 for driving the main connecting seat 4 to rise and fall in the vertical direction. The lifting drive 15 is a lifting hydraulic cylinder, the bottom end of which is fixed to the bracket 11, and the secondary support tube 122 is sleeved on the outer periphery of the lifting hydraulic cylinder; the piston rod of the lifting hydraulic cylinder is passed through the secondary support tube 122 and fixedly connected to the bottom end of the main connecting seat 4, so as to realize the driving connection between the lifting drive 15 and the main connecting seat 4. Through the above arrangement, the lifting drive 15 can cooperate with the lifting cylinder 13 to drive the flip frame 2 to rise and fall in the vertical direction, which is conducive to further increasing the lifting range of the flip frame 2 and facilitating the improvement of the applicability of the flip device.

[0045] Reference Figure 1 and Figure 4The bottom end of the secondary support tube 122 is provided with an articulated seat 1221, which is penetrated through the main support tube 121 and extends out of the main support tube 121. The outside of the main support tube 121 is provided with a long through hole 1211 for the articulated seat to slide up and down, so that the articulated seat can be lifted and lowered together with the secondary support tube 122. The end of the telescopic driving member 3 is rotatably connected to the articulated seat 1221 through a pin, so that one end of the telescopic driving member 3 is rotatably connected to the bottom end of the support rod 12.

[0046] A plurality of diagonal braces 14 are connected between the main support tube 121 and the bracket 11 . In the present embodiment, the diagonal braces 14 are I-beams, one end of which is welded and fixed to the bracket 11 , and the other end of which is welded and fixed to the top of the main support tube 121 .

[0047] The implementation principle of the embodiment of the present application is: before flipping the refrigeration equipment, the flip frame 2 is driven to move upward by the lifting cylinder 13 in cooperation with the lifting drive 15, and the support frame 21 of the flip frame 2 is driven to flip to a horizontal state by the telescopic drive 3, and then the flip frame 2 is driven to move downward by the lifting cylinder 13 in cooperation with the lifting drive 15 to lower the center of gravity of the flip frame 2.

[0048] When flipping the refrigeration equipment, after the refrigeration equipment to be flipped is lifted above the support frame 21 by the transfer vehicle, the support frame 21 of the flip frame 2 is driven upward by the lifting cylinder 13 in cooperation with the lifting drive 15 until the support frame 21 lifts the refrigeration equipment. After the transfer vehicle is driven out of the flipping area, the flip frame 2 is driven upward by the lifting cylinder 13 in cooperation with the lifting drive 15 until the distance between the flip frame 2 and the ground meets the flipping range requirement of the flip frame 2; then the flip frame 2 is driven by the telescopic drive 3 to flip the refrigeration equipment until the support frame 21 of the flip frame 2 and the refrigeration equipment are in a vertical state, and the flipping operation of the refrigeration equipment can be completed.

[0049] The present application drives the flip frame 2 to flip the refrigeration device through the telescopic driving member 3, which is beneficial to improving the reliability and stability of the refrigeration device when flipping, and the overall work efficiency is high.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
