[0036] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0037] Please refer to Figures 1-4 , Figure 1 Structure diagram of a specific embodiment of the four-way valve assembly provided by the present application; Figure 2For Figure 1 Top view of the four-way valve assembly; Figure 3 For Figure 1 Front view of the four-way valve assembly; Figure 4 For Figure 1 Partial structural schematic view of the hoisting device in the four-way valve assembly.

[0038] The embodiment provides a hoisting device 1 for hoisting a four-way valve 01, the four-way valve 01 comprising a valve body 011, an E connecting pipe 012, an S connecting pipe 013 and a C connecting pipe 014, it can be seen that the E connecting pipe 012, the S connecting pipe 013 and the C connecting pipe 014 are located on one side of the valve body 011, and the hoisting device 1 comprises:

[0039] A hoisting base 11, the hoisting base 11 comprising a valve body supporting portion 111 for supporting the valve body 011;

[0040] A hoisting fixing plate 12, the hoisting fixing plate 12 comprising a connecting pipe supporting plate 121, the connecting pipe supporting plate 121 extending along a horizontal direction, the connecting pipe supporting plate 121 being capable of supporting at least one of the E connecting pipe 012, the S connecting pipe 013 and the C connecting pipe 014, the position of the hoisting fixing plate 12 being adjustable along a height direction of the hoisting base 11, and the hoisting fixing plate 12 and the hoisting base 11 being detachably fixedly connected.

[0041] The "height direction" herein refers to: Figure 1 The height direction of the hoisting base 11 shown in FIG. 1.

[0042] The analysis shows that the prior art increases the four-way valve of the hoisting device and the system pipe after welding, and the system pipe has an upward inclination problem, which is mainly caused by the upward inclination of the S connector pipe of the four-way valve, while the inclination of the E connector pipe, the S connector pipe and the C connector pipe is consistent. In order to solve the technical problems existing in the prior art, the hoisting device 1 of the embodiment comprises a split type hoisting base 11 and a hoisting fixing plate 12. Before the four-way valve 01 is installed in the hoisting device 1, the hoisting fixing plate 12 can be connected to the hoisting base 11, and the position of the connector support plate 121 relative to the hoisting base 11 is adjusted to the lowermost position to avoid interference with the installation of the four-way valve 01; then, the installation of the four-way valve 01 can be carried out. Specifically, the valve body 011 of the four-way valve 01 can be placed on the valve body support part 111 of the hoisting base 11, and then the installation angle of the four-way valve 01 is adjusted to ensure that the S connector pipe 013 has a preset level, that is, the E connector pipe 012, the S connector pipe 013 and the C connector pipe 014 have a preset level; then, the position of the connector support plate 121 relative to the hoisting base 11 is adjusted upward, so that the connector support plate 121 supports at least one of the E connector pipe 012, the S connector pipe 013 and the C connector pipe 014, which plays a supporting role for the four-way valve 01; finally, the four-way valve 01 is fixed to the hoisting device 1 to ensure that the four-way valve 01 is stably located at the preset installation position, and the system pipe has a preset level after being connected to the four-way valve 01, solving the problem of upward inclination of the system pipe after being welded with the four-way valve, and ensuring smooth connection of the four-way valve 01 and the system.

[0043] By Figure 1 It can be seen that in the embodiment, the E connector pipe 012, the S connector pipe 013 and the C connector pipe 014 are all supported on the connector support plate 121, which increases the support area of the hoisting device 1 for the four-way valve 01 and improves the support stability of the hoisting device 1 for the four-way valve 01, thereby ensuring the installation position accuracy of the four-way valve 01.

[0044] Please refer to 4- Figure 6 , Figure 4 For Figure 1 The local structure diagram of the hoisting device in the four-way valve assembly; Figure 5 For Figure 4 The structure diagram of the hoisting base in the embodiment; Figure 6 For Figure 4 The structure diagram of the hoisting fixing plate in the embodiment.

[0045] As known from the foregoing, the position of the hoisting fixing plate 12 connected to the hoisting base 11 is adjustable along the height direction of the hoisting base 11, and the hoisting fixing plate 12 and the hoisting base 11 are detachably fixedly connected. In the embodiment, the hoisting base 11 comprises a first connecting wall 112 extending along the height direction of the hoisting base 11, and the hoisting fixing plate 12 comprises a second connecting wall 122 extending along the height direction of the hoisting base 11, one of the first connecting wall 112 and the second connecting wall 122 is provided with a first connecting hole a1, and the other is correspondingly provided with a first strip-shaped hole b1 extending along the height direction of the hoisting base 11.

[0046] In combination Figure 3 As shown in the figure, the hoisting device 1 further comprises a first connecting piece 13, which passes through the first strip-shaped hole b1 and the corresponding first connecting hole a1 to lock or unlock the first connecting wall 112 and the second connecting wall 122.

[0047] As arranged above, before the four-way valve 01 is installed on the hoisting device 1, the first connecting piece 13 can be screwed and turned to unlock the first connecting wall 112 and the second connecting wall 122, so as to adjust the position of the pipe support plate 121 relative to the hoisting base 11 to the lowermost position; after the four-way valve 01 is installed on the hoisting device 1 and the four-way valve 01 is adjusted to have a preset level, the hoisting fixing plate 12 is adjusted upward so that the pipe support plate 121 supports at least one of the E pipe 012, the S pipe 013 and the C pipe 014, thereby playing a supporting role on the four-way valve 01; at this time, the first connecting piece 13 can be used to lock the first connecting wall 112 and the second connecting wall 122 to ensure the position stability of the pipe support plate 121.

[0048] As can be seen, the first connecting piece 13 is used to lock or unlock the first connecting wall 112 and the second connecting wall 122 in the embodiment, which can ensure the position stability of the pipe support plate 121, and the first strip-shaped hole b1 is arranged to facilitate the adjustment of the position of the pipe support plate 121, thereby improving the operation convenience.

[0049] As Figure 5 and Figure 6 As can be seen, in the embodiment, the first connecting hole a1 is arranged on the first connecting wall 112, and the first strip-shaped hole b1 is arranged on the second connecting wall 122. In some other embodiments of the application, the first connecting hole a1 is arranged on the second connecting wall 122, and the first strip-shaped hole b1 is arranged on the first connecting wall 112.

[0050] In some embodiments of the present application, the first connecting hole a1 is a threaded hole, the first connecting piece 13 is a connecting bolt, the shank of the first connecting piece 13 passes through the first strip-shaped hole b1 and is threadedly connected with the first connecting hole a1, the head of the first connecting piece 13 abuts the second connecting wall 122 against the first connecting wall 112, so as to lock the first connecting wall 112 and the second connecting wall 122; when it is necessary to adjust the position of the pipe connecting support plate 121, the first connecting piece 13 can be screwed to release the second connecting wall 122 by the head of the first connecting piece 13, at this time, the hoisting fixing plate 12 will move downward under the action of gravity until the shank of the first connecting piece 13 and the upper end contour of the first strip-shaped hole b1 abut, at this time, the pipe connecting support plate 121 is in the lowermost position.

[0051] Of course, it is conceivable that the first connecting piece 13 can also be a bolt-nut assembly, in which scheme the first connecting hole a1 does not need to be machined into a threaded hole, but is threadedly matched with a nut to lock the first connecting wall 112 and the second connecting wall 122.

[0052] Please refer to Figure 1 , Figure 7 and Figure 8 , Figure 7 for Figure 1 the structure diagram of the hoisting hoop in the four-way valve assembly; Figure 8 for Figure 7 the structure diagram of the hoisting hoop in the second angle.

[0053] In some embodiments of the present application, the hoisting device 1 further comprises a hoisting hoop 14, the hoisting hoop 14 comprises a pipe connecting pressing plate 141 extending along the length direction of the valve body 011, the pipe connecting pressing plate 141 is located above the pipe connecting support plate 121, the position of the hoisting hoop 14 connected to the hoisting base 11 or the hoisting fixing plate 12 is adjustable in the height direction, and the hoisting base 11 or the hoisting fixing plate 12 is detachably and fixedly connected with the hoisting hoop 14.

[0054] The hoisting hoop 14 is connected to the hoisting base 11 or the hoisting fixing plate 12, and the connection manners are the same, which is described below by taking the hoisting hoop 14 connected to the hoisting base 11 as an example.

[0055] As arranged above, before the four-way valve 01 is installed on the lifting device 1, the lifting clamp 14 can be first detached to avoid interference with the installation of the four-way valve 01; then the four-way valve 01 is installed on the lifting device 1, and the four-way valve 01 is adjusted to have a preset levelness, then the lifting fixing plate 12 is adjusted upward to support at least one of the E connecting pipe 012, the S connecting pipe 013 and the C connecting pipe 014, playing a supporting role for the four-way valve 01, and the connecting pipe supporting plate 121 forms a lower limiting wall of at least one of the E connecting pipe 012, the S connecting pipe 013 and the C connecting pipe 014; then the connecting pipe pressing plate 141 is connected to the lifting base 11, and the connecting position of the connecting pipe pressing plate 141 is adjusted so that the connecting pipe pressing plate 141 abuts against the upper side wall of at least one of the E connecting pipe 012, the S connecting pipe 013 and the C connecting pipe 014, and the connecting pipe pressing plate 141 forms an upper limiting wall of at least one of the E connecting pipe 012, the S connecting pipe 013 and the C connecting pipe 014. In this way, at least one of the E connecting pipe 012, the S connecting pipe 013 and the C connecting pipe 014 is limitedly installed between the connecting pipe supporting plate 121 and the connecting pipe pressing plate 141, preventing the position of the E connecting pipe 012, the S connecting pipe 013 and the C connecting pipe 014 from being shifted up and down, ensuring the levelness of the E connecting pipe 012, the S connecting pipe 013 and the C connecting pipe 014, and further improving the installation position accuracy of the four-way valve 01.

[0056] Further, as shown in Figure 1 , Figure 5 and Figure 7 , the lifting clamp 14 has a third connecting wall 142 extending downward at both ends in the length direction of the connecting pipe pressing plate 141, and the lifting base 11 or the lifting fixing plate 12 has a fourth connecting wall 113 extending upward at both ends in the length direction of the connecting pipe supporting plate 121, one of the third connecting wall 142 and the fourth connecting wall 113 is provided with a second connecting hole a2, and the other is correspondingly provided with a second strip-shaped hole b2 extending in the height direction;

[0057] The lifting device 1 further comprises a second connecting piece 15, which passes through the second strip-shaped hole b2 and the corresponding second connecting hole a2 to lock or unlock the third connecting wall 142 and the fourth connecting wall 113.

[0058] As arranged above, before the four-way valve 01 is installed on the hoisting device 1, the second connecting piece 15 can be screwed first, and the third connecting wall 142 and the fourth connecting wall 113 are unlocked, so as to facilitate the disassembly of the hoisting clamp 14; after the four-way valve 01 is installed on the hoisting device 1 and the four-way valve 01 is adjusted to have a preset level, the hoisting fixing plate 12 is adjusted upward, so that the pipe support plate 121 supports at least one of the E pipe 012, the S pipe 013 and the C pipe 014, and plays a supporting role on the four-way valve 01, and then the hoisting clamp 14 is installed, so that the pipe pressing plate 141 is located above the pipe support plate 121, the third connecting wall 142 and the fourth connecting wall 113 are oppositely arranged, the position of the hoisting clamp 14 is adjusted, so that the pipe pressing plate 141 abuts against the upper side wall of at least one of the E pipe 012, the S pipe 013 and the C pipe 014, at this time, the second connecting piece 15 passes through the second slot b2 and the corresponding second connecting hole a2, and the third connecting wall 142 and the fourth connecting wall 113 are locked, and the installation of the hoisting clamp 14 is completed.

[0059] It can be seen that, in the embodiment, the second connecting hole a2 is arranged on the fourth connecting wall 113, and the second slot b2 is arranged on the third connecting wall 142. In some other embodiments of the present application, the second connecting hole a2 is arranged on the third connecting wall 142, and the second slot b2 is arranged on the fourth connecting wall 113.

[0060] By Figure 5 and Figure 8 It can be seen that, in the embodiment, the second connecting hole a2 is arranged on the fourth connecting wall 113, and the second slot b2 is arranged on the third connecting wall 142. In some other embodiments of the present application, the second connecting hole a2 is arranged on the third connecting wall 142, and the second slot b2 is arranged on the fourth connecting wall 113.

[0061] In some embodiments of the present application, the second connecting hole a2 is a threaded hole, the second connecting piece 15 is a connecting bolt, the shank of the second connecting piece 15 passes through the second slot b2 and is threadedly connected with the second connecting hole a2, the head of the second connecting piece 15 abuts the third connecting wall 142 against the fourth connecting wall 113, and the locking of the third connecting wall 142 and the fourth connecting wall 113 is realized; when the position of the pipe pressing plate 141 needs to be adjusted, the second connecting piece 15 can be screwed, so that the head of the second connecting piece 15 loosens the third connecting wall 142, and at this time, the position of the pipe pressing plate 141 can be adjusted.

[0062] Of course, it can be conceived that the second connecting piece 15 can also be a bolt and nut assembly, in which scheme the second connecting hole a2 does not need to be processed into a threaded hole, but is threadedly matched with the bolt and the nut, so as to realize the locking of the third connecting wall 142 and the fourth connecting wall 113.

[0063] Please continue to refer to Figure 1and Figure 4 In some embodiments of the present application, the hoisting base 11 further comprises a bottom plate 114, and the valve body support part 111 is connected to the bottom plate 114;

[0064] The hoisting device further comprises a hoop 16, and the hoop 16 is connected to the bottom plate 114, and in the installed state, the hoop 16 is wrapped around the outer periphery of the valve body 011.

[0065] As arranged above, in the installed state, the hoop 16 is wrapped around the outer periphery of the valve body 011, which can effectively fix the valve body 011, prevent the valve body 011 from deviating due to vibration, collision, etc. during hoisting and transportation, and ensure the levelness of the E connecting pipe 012, the S connecting pipe 013 and the C connecting pipe 014, thereby further improving the installation position accuracy of the four-way valve 01.

[0066] Specifically, the hoop 16 can comprise a wrapping part in an arc shape matching the outer contour of the valve body 011, and the hoop 16 further comprises two connecting parts connected to both ends of the extension direction of the wrapping part, and the connecting parts are used to connect with the bottom plate 114.

[0067] Wherein, the connection manner of the hoop 16 and the bottom plate 114 is not limited, such as in some embodiments of the present application, the hoop 16 and the bottom plate 114 are fixed by threaded connections such as bolts, which not only ensures the connection reliability of the hoop 16 and the bottom plate 114, but also can realize the detachable connection of the hoop 16 and the bottom plate 114, and the installation and disassembly of the four-way valve 01 is more convenient and fast. In some other embodiments of the present application, the hoop 16 and the bottom plate 114 are fixed by clamping.

[0068] Please refer to Figure 4 and Figure 9 , Figure 9 To Figure 5 The second angle structure schematic diagram of the hoisting base.

[0069] In some embodiments of the present application, the valve body support part 111 comprises two oppositely arranged support seats 111a, and the two support seats 111a are spaced apart along the length direction of the hoisting base 11 (i.e. the length direction of the valve body 011), and the support seat 111a has an installation slot A with an open upper end, and the inner contour of the part at the closed end of the installation slot A matches the outer contour of the valve body 011.

[0070] As arranged above, in the installed state, the two ends of the valve body 011 in the length direction are supported inside the installation slot A, and the outer contour of the valve body 011 is fitted with the inner contour of the part at the closed end of the installation slot A, thereby increasing the support area of the valve body 011 and ensuring the installation stability of the valve body 011.

[0071] By Figure 9It can be seen that the side wall located at the opening end of the mounting groove A is inclinedly extended, and extends along the direction from the closed end of the mounting groove A to the opening end of the mounting groove A, and extends away from the interior of the mounting groove A, so that the width of the opening end of the mounting groove A gradually increases. In this way, the inclinedly extended side wall can play a guiding role, facilitating the valve body 011 to enter the interior of the mounting groove A during assembly, ensuring smooth installation of the valve body 011, and improving the installation efficiency of the valve body 011.

[0072] As shown in Figure 4 and Figure 5 In some embodiments, the hoisting base 11 is also provided with a weight-reducing hole 114a to reduce the weight of the hoisting device 1.

[0073] Specifically, the weight-reducing hole 114a can be arranged on the bottom plate 114 of the hoisting base 11.

[0074] By Figure 5 It can be seen that the upper end of the support seat 111a is provided with a hoisting hole B on both sides of the mounting groove A, and the lifting equipment can be connected with the hoisting device 1 through the hoisting hole B to realize the transfer of the four-way valve 01.
