In this text, "one" not only means "only this one", but also can mean "more than one", and "several" includes "two" and "more than two".

[0033] In this text, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "joined" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific situations.

[0034] In addition, in the description of this application, the terms "first", "second", etc. are only used for differential description and cannot be understood as indicating or implying relative importance.

[0035] As Figures 1-9 shown, the transfer machine clamping and installation device includes: a first clamping ring 3, which has a first clamping portion 301 and two first connection portions 302. The first clamping portion 301 is "C"-shaped, and the two first connection portions 302 are located on both sides of the first clamping portion 301. The first connection portion 302 has a first connection hole 303; a second clamping ring 4, which has a second clamping portion 401 and two second connection portions 402. The second clamping portion 401 is "U"-shaped, and the first clamping portion 301 slides inside the second clamping portion 401. After the first clamping portion 301 and the second clamping portion 401 are butted, they form an annular clamping structure, and the clamping structure is used to be sleeved in the annular groove 201 at the lower part of the connection head 2. The second connection portions 402 are located at the two ends of the second clamping portion 401. The second connection portion 402 has a second connection hole 403. The second connection portions 402 and the first connection portions 302 are distributed vertically, and the second connection holes 403 correspond to the first connection holes 303 one by one.

[0036] During use, the upper end of the walking trolley 1 has a through hole, the lower part of the connection head 2 of the transfer machine passes through the through hole and enters the lower side of the walking trolley 1. Then, the first clamping ring 3 and the second clamping ring 4 approach relatively from both sides of the connection head 2. The first clamping portion 301 and the second clamping portion 401 are butted and clamped in the annular groove 201 at the lower part of the connection head 2. The diameters of the first clamping ring 3 and the second clamping ring 4 are larger than the through hole on the walking trolley 1, so that the connection head 2 will not break away from the walking trolley 1 and can drive the walking trolley 1 to move back and forth.

[0037] The first clamping portion 301 and the second clamping portion 401 are both arc-shaped protruding structures, which can be inserted into the annular groove 201. The second clamping portion 401 is "U"-shaped, and the first clamping portion 301 is "C"-shaped and can slide in the second clamping portion 401, which is beneficial to reducing the overall volume of the first clamping ring 3 and the second clamping ring 4, reducing space occupancy, and better operating in a small space.

[0038] The first connection part 302 can be located at the front and rear sides of the first retaining ring 3, and the second connection part 402 can be located at the two ends of the "U" shape. The first connection part 302 and the second connection part 402 are distributed up and down. After the upper and lower positions are relative, the first connection hole 303 and the second connection hole 403 are connected up and down, and can be connected by bolts.

[0039] The first clamp ring 3 and the second clamp ring 4 can be fixed to the trolley 1 by bolt structures or other connecting parts, that is, the transfer machine connector 2 and the trolley 1 can be completely fixed in the front-to-back direction and the up-down direction. The first clamp ring 3 and the second clamp ring 4 can also be located below the trolley 1 and float up and down in a certain space.

[0040] Further, after the first clamping portion 301 and the second clamping portion 401 form an embracing structure, the first connecting portion 302 and the second connecting portion 402 are connected by bolts.

[0041] When in use, the first connection portion 302 and the second connection portion 402 may be connected by bolts, or by structures such as latches, to achieve a detachable connection.

[0042] Furthermore, the first clamp ring 3 and the second clamp ring 4 are relatively movably arranged on the traveling trolley 1 and are located at the lower side of the traveling trolley 1 . After the first clamp ring 3 and the second clamp ring 4 move relatively, they are close to or away from the connecting head 2 .

[0043] When in use, in addition to holding the first clamp ring 3 and the second clamp ring 4 to be sleeved on the connector 2, the first clamp ring 3 and the second clamp ring 4 can also be relatively slidably arranged at the lower side of the trolley 1, so as to reduce the situation of holding the trolley 1 and extending it into the lower part of the trolley 1, improve safety, and make it more convenient to operate outside the trolley 1. Of course, the first clamp ring 3 and the second clamp ring 4 can still be raised and lowered within a certain height space relative to the trolley 1.

[0044] Furthermore, it also includes a first driving device 5 for driving the first retaining ring 3 to move, and the first driving device 5 includes: a slide 501, having a slide groove 5011, and the first retaining ring 3 slides up and down along the slide groove 5011; a driving rod 502, one end of which is set at one end of the slide 501, and the other end passes through one side of the traveling trolley 1, and the driving rod 502 is slidably set on the lower side of the traveling trolley 1.

[0045] It further includes a second driving device 6 for driving the second snap ring 4 to move. The second driving device 6 has the same structure as the first driving device 5.

[0046] During use, the first driving device 5 drives the first snap ring 3 to move left and right. The first snap ring 3 slides up and down relative to the sliding seat 501, which can meet the floating requirements in the height direction. Through the sliding groove 5011, the first snap ring 3 slides left and right on the walking trolley 1 following the sliding seat 501. A support can be arranged on the lower side of the walking trolley 1. The driving rod 502 penetrates through the support and slides left and right with the support to position the sliding seat 501 in the height direction.

[0047] The second driving device 6 can have the same structure as the first driving device 5. The second snap ring 4 is slidably connected to the sliding seat 501 of the second driving device 6. The second driving device 6 and the first driving device 5 are arranged opposite to each other left and right.

[0048] Further, a limiting plate 5012 is provided on the sliding seat 501 below the sliding groove 5011.

[0049] During use, the sliding groove 5011 of the sliding seat 501 provides guidance for the up and down movement of the first snap ring 3 or the second snap ring 4. A limiting plate 5012 is provided below the sliding groove 5011, which can limit the lowest position of the first snap ring 3 and the second snap ring 4 to prevent them from detaching. At the same time, during installation, the following method can be adopted. When the first snap ring 3 and the second snap ring 4 are in contact with the limiting plate 5012, the connecting head 2 is exactly at the lowest position of the walking trolley 1. At this time, the first snap ring 3 and the second snap ring 4 are close to the connecting head 2, and the sleeving connection with the annular groove 201 on the connecting head 2 can be achieved, making the installation more convenient.

[0050] Further, a guiding rod 5013 is provided on one side of the sliding seat 501. The end of the driving rod 502 is a tubular structure, and the end of the driving rod 502 is movably sleeved on the guiding rod 5013. The first driving device further includes: a buffer compression spring 503, with one end acting on the sliding seat 501 and the other end acting on the driving rod 502.

[0051] The end of the driving rod 502 located outside the walking trolley 1 has a limiting hole 5021; it further includes: a positioning pin 504, inserted on the walking trolley 1 and passing through the limiting hole 5021.

[0052] During use, the end of the driving rod 502 is movably sleeved on the guiding rod 5013 on the sliding seat 501, and the two can relatively move in a certain distance in the left and right directions. At the same time, the buffer compression spring 503 is provided to provide a pressing force. When the driving rod 502 pushes the sliding seat 501, the buffer compression spring 503 applies pressure to the sliding seat 501. When problems such as shaking or deflection occur in the connecting head 2 of the transfer machine, the compression spring can be compressed to avoid equipment damage caused by strong limiting. The buffer compression spring 503 can be fixedly connected to the sliding seat 501 and the driving rod 502.

[0053] After the first snap ring 3 and the second snap ring 4 are sleeved around the connector 2, the positioning pin 504 can be inserted into the traveling trolley 1 and the limiting hole 5021 for positioning to maintain the sleeved connection. The arrangement of the buffer compression spring 503 can be coordinated to ensure that both the first snap ring 3 and the second snap ring 4 can stably abut against the connector 2, avoiding position deviation that may cause the positioning pin 504 to be unable to be inserted into the limiting hole 5021. A sleeve can be welded on the upper side of the traveling trolley 1 for the positioning pin 504 to be inserted, and it only needs to be opposite to the position of the limiting hole 5021.

[0054] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
