[0031] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions, they cannot be understood as indicating or implying relative importance.

[0032] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0033] Please refer to Figure 1 , in the embodiment of the present application, an H-frame adjustment tooling 10 is provided. The H-frame adjustment tooling 10 is used to adjust the posture of the H-frame to avoid the problem of transportation accidents of the conveyor caused by the inclination of the H-frame. Among them, the H-frame adjustment tooling 10 provided in this embodiment can solve the technical problems in the prior art that it is time-consuming and laborious to adjust the H-frame and there are potential safety hazards.

[0034] In this embodiment, the H-frame adjustment tooling 10 includes a support frame 100, a lever assembly 200, a bearing 300, and a hook 400. The lever assembly 200 includes a rotation connection portion 210, a lifting end 220, and a force application end 230. The lifting end 220 and the force application end 230 are provided on opposite sides of the rotation connection portion 210. The rotation connection portion 210 is rotatably connected to the support frame 100 to form a lever; the rotation connection portion 210 is a ratchet structure. The outer ring of the bearing 300 is fixedly connected to one end of the lifting end 220 away from the rotation connection portion 210; the bearing 300 is horizontally arranged as a whole. The hook 400 is bent in a U shape for hanging the cross beam; the hook 400 is fixedly connected to the inner ring of the bearing 300.

[0035] Among them, the rotating connection part 210 is arranged in a ratchet structure, which enables the lifting end 220 to be lifted unidirectionally. Even if the force applied to the force application end 230 is withdrawn, the locking of the lifting end 220 can still be achieved. It should be noted that the ratchet structure includes a rotating gear and a pawl. In other words, the rotating connection part 210 includes a rotating gear and a pawl. The rotating gear is fixedly connected to the lifting end 220 and the force application end 230 through its shaft part, so that the rotating gear can rotate following the lifting end 220 and the force application end 230. That is, when the force application end 230 is pressed down and at the same time drives the lifting end 220 to lift, the rotating gear rotates accordingly; the pawl is connected to the support frame 100, and the pawl can move relative to the support frame 100 to form a first state and a second state at two positions within the movement range of the pawl; in the first state, the pawl is close to the rotating gear, and the rotating gear can only rotate unidirectionally, that is, the lifting end 220 can only be lifted; in the second state, the pawl is far from the rotating gear, and the rotating gear can rotate freely, and at this time, the reset of the lifting end 220 can be realized. Among them, the ratchet structure formed by the rotating connection part 210 is the same as the ratchet structure of a ratchet wrench in the prior art, and will not be elaborated here.

[0036] As mentioned above, in the case where the H-frame needs to be adjusted, the cross beam of the H-frame is hung on the hook 400, and then a force is applied to the force application end 230. Through the lever action, the lifting end 220 is lifted, and then the hook 400 and the cross beam are driven to lift, so that the lifting of the H-frame can be realized, which is convenient for adjusting the posture of the H-frame. Among them, since the rotating connection part 210 is a ratchet structure, the lever assembly 200 can form self-locking after rotation. Furthermore, after the lifting end 220 is lifted, the locking of the lifting end 220 can be achieved, ensuring the stability of the H-frame after being lifted, and the purpose of adjusting the posture of the H-frame by one person can also be realized. In addition, since the hook 400 is connected to the inner ring of the horizontally arranged bearing 300, the hook 400 can rotate freely, which is convenient for the H-frame adjustment tooling 10 to operate in a narrow space and improves the applicability of the H-frame adjustment tooling 10.

[0037] It should be understood that in other embodiments of the present application, the setting of the bearing 300 can also be cancelled. In other words, the hook 400 can be directly connected to the front end of the lifting end 220.

[0038] In this embodiment, the support frame 100 includes a column assembly 110 and a plurality of support feet 120; the ends of the plurality of support feet 120 are connected to the bottom of the column assembly 110, and the plurality of support feet 120 are inclined relative to the column assembly 110 to support the column assembly 110; the rotary connection portion 210 is connected to the top of the column assembly 110. Among them, the plurality of support feet 120 are arranged at the bottom of the column assembly 110 in a divergent manner. Specifically, any two adjacent support feet 120 are arranged at an angle, and one end of the plurality of support feet 120 away from the column assembly 110 encloses a polygon to facilitate standing on the bearing surface.

[0039] Optionally, in this embodiment, the number of the support feet 120 is three. It should be understood that in other embodiments, the number of the support feet 120 can also be four, five or more.

[0040] Further, please refer to Figure 1 and Figure 2 , the column assembly 110 includes a first column body 111 and a second column body 112, and the first column body 111 is telescopically connected to the second column body 112; the plurality of support feet 120 are arranged at the bottom of the second column body 112; the rotary connection portion 210 is connected to the top of the first column body 111. By the telescopic movement of the first column body 111 relative to the second column body 112, the height of the rotary connection portion 210 on the first column body 111 can be adjusted, so that the overall height of the H-frame adjustment tooling 10 can be adjusted, which is convenient for adapting to the height of the cross beam in the H-frame to be adjusted.

[0041] It should be noted that a locking structure can be provided between the first column body 111 and the second column body 112 to lock the position of the first column body 111 through the locking structure after the first column body 111 is telescoped relative to the second column body 112 in place, so as to ensure the stability of the first column body 111, and thus ensure the overall stability of the lever assembly 200. For example, a threaded hole is opened on the second column body 112, and the threaded hole communicates with the internal space of the second column body 112. When the first column body 111 is telescoped in place, a screw is screwed into the threaded hole, and the first column body 111 is held by the screw to achieve the firmness of the first column body 111. Of course, in other embodiments, other methods can also be used to set the locking structure. For example, the first column and the second column are in threaded cooperation, etc.

[0042] In addition, in this embodiment, the support frame 100 further includes a support plate 130, and the support plate 130 is arranged at the bottom of the plurality of support feet 120 for supporting the plurality of support feet 120. Optionally, the support plate 130 can be made of a hard plate such as a steel plate. By providing support to the plurality of support feet 120 through the support plate 130, in areas where the ground is soft, the support feet 120 can be prevented from inserting into the ground, so as to ensure the overall stability of the H-frame adjustment tooling 10 through the support plate 130, which is beneficial to stably complete the stable adjustment of the H-frame.

[0043] Optionally, a plurality of insertion portions (not shown in the figure) are provided on the support plate 130, and the plurality of support feet 120 are respectively detachably inserted into the plurality of insertion portions. On the one hand, through the assembly of the insertion portions and the support feet 120, the stability of the support feet 120 on the support plate 130 is improved, the support feet 120 are prevented from sliding, and the overall stability of the H-frame adjustment tooling 10 is ensured. On the other hand, through the detachable installation of the insertion portions and the support feet 120, when the support plate 130 is not needed, the support plate 130 can also be removed, which is convenient for arranging the H-frame adjustment tooling 10.

[0044] In this embodiment, a support connection ear is provided on the gear core pin shaft of the rotation connection portion 210, and the support connection ear is connected to the support frame 100. The installation with the column assembly 110 can be realized through the support connection ear, which can simplify the connection method between the rotation connection portion 210 and the column assembly 110 and reduce the assembly difficulty.

[0045] In this embodiment, please refer to Figure 1 and Figure 3 , at one end of the force application end 230 away from the rotation connection portion 210, a first connection sleeve 231 is provided, and a first socket groove 232 is provided on the first connection sleeve 231; the H-frame adjustment tooling 10 further includes an extension rod 240, and an insertion block 243 adapted to the first socket groove 232 is provided at the end of the extension rod 240, and the insertion block 243 is detachably inserted into the first socket groove 232.

[0046] In the case where the weight of the conveyor carried by the H-frame is relatively high, by inserting the extension rod 240 into the end of the force application end 230, the length of the force application end 230 can be extended, which is convenient for the operator to apply a force, reduces the force required by the operator, and reduces the operation difficulty of the operator.

[0047] Furthermore, a second connection sleeve 241 is provided at the end of the extension rod 240 away from the insertion block 243, and a second socket groove 242 is provided on the second connection sleeve 241, and the second socket groove 242 is used for detachably cooperating with the insertion block 243 of another extension rod 240. That is to say, a plurality of extension rods 240 can be provided, and by sequentially inserting the plurality of extension rods 240 into the end of the force application end 230, the purpose of extending the force application end 230 as required can be achieved.

[0048] In summary, when the crossbeam of the H-frame needs to be adjusted, the crossbeam of the H-frame is hung on the hook 400, and then a force is applied to the force application end 230. Through the lever action, the lifting end 220 is lifted, and then the hook 400 and the crossbeam are driven to lift, so that the H-frame can be lifted, which is convenient for adjusting the attitude of the H-frame. Among them, since the rotating connection part 210 is a ratchet structure, the lever assembly 200 can form self-locking after rotation. Furthermore, after the lifting end 220 is lifted, the lifting end 220 can be locked, ensuring the stability of the H-frame after being lifted, and also achieving the purpose of adjusting the attitude of the H-frame by one person. In addition, since the hook 400 is connected to the inner ring of the horizontally arranged bearing 300, the hook 400 can rotate freely, which is convenient for the H-frame adjustment tooling 10 to operate in a narrow space and improves the applicability of the H-frame adjustment tooling 10. By supporting the plurality of support feet 120 through the support plate 130, the bearing capacity of the base is improved, and it is prevented from sinking when used in muddy and soft ground environments. Through the insertion and fixation of the insertion part, the connection is safe, reliable and detachable, and is suitable for different environments. In addition, through the arrangement of the extension rod 240, the length of the force application end 230 can be extended as needed, reducing the force required by the operator and the operation difficulty of the operator.

[0049] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
