Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, and more specifically, to a wall-mounted pneumatic balancing crane. Background Art

[0002] A balance crane is a new type of material lifting equipment. According to its structure, it is mainly divided into mechanical balance crane, pneumatic balance crane and hydraulic balance crane. For pneumatic balance crane, it mainly uses a combination of a hanger and pneumatic equipment to drive the hanger to adjust its position through pneumatic means. At the same time, some hangers of this type will also use pneumatic (air source) to absorb objects to achieve lifting.

[0003] The position adjustment of the hanger is driven by pneumatic equipment, which has the characteristics of fast speed and precise control of the lifting position. At the same time, the transmission is relatively direct during the adjustment of the hanger position. For this type of balancing crane, the position of the hanger as a whole is mainly adjusted by the cylinder, and the hook connected to the hanging line on the frame is used to lift the object;

[0004] Since the hanger of traditional balancing cranes is mostly an independent frame, the object is connected through the hook on the frame to cooperate with the winding and releasing of the line to achieve the lifting effect. When the object to be lifted is small and within the allowable lifting range, it can be directly lifted through the frame. When the object to be lifted is large and it is necessary to ensure that the object is in a specific position, it is necessary to install an external limit component on the lifting rope or hook, such as a lifting rope with multiple branches or a corresponding carrier plate. The installation and disassembly of multiple branch lifting ropes or carrier plates is cumbersome and time-consuming. In addition, the independent hanger structure needs to go back and forth many times when lifting multiple or different types of objects, thereby prolonging the overall process of the lifting operation.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a wall-mounted pneumatic balance crane. Utility Model Content

[0030] like Figure 1-5 As shown, the utility model provides a wall-mounted pneumatic balance crane, including two groups of cylinders 1 installed inside the wall and fixed plates 2 corresponding to the positions of the cylinders 1 and installed on the wall surface, the push end of the cylinder 1 is connected through the fixed plate 2, and also includes a main adjustment member 3, a main frame 4, a first hanger 5 and a second hanger 6, which are specifically described as follows:

[0031] The main adjusting member 3 is connected to the driving ends of the two groups of cylinders 1 and is used to adjust the overall lateral angle of the hanger. The main adjusting member 3 mainly adjusts the position of the entire hanger, that is, adjusts the overall lateral angle of the hanger, and makes corresponding position adjustments according to the lifting position;

[0032] The main frame 4 is connected to the adjustment end of the main adjustment member 3. The end of the main frame 4 opposite to the connection end of the main adjustment member 3 is provided with a rotating seat 401 capable of longitudinal angle adjustment and a second motor 402 for driving the rotating seat 401.

[0033] Specifically, the main frame 4 is the main connecting member. While serving as a supporting connection, the first hanger 5 can be longitudinally adjusted through the rotating seat 401 on the main frame 4, and cooperated with the above-mentioned main adjusting member 3 to achieve a horizontal and vertical position adjustment effect, so as to accurately adjust the lifting position;

[0034] The first hanger 5 is connected to the rotating seat 401. A third motor 501 is arranged on the side wall of the first hanger 5. A first hanging wire mechanism for lifting is arranged at the end of the first hanger 5 opposite to the connection end of the main frame 4. The first hanger 5 is a strip-shaped hollow structure as a whole. The first hanger 5 is the main hanger. On the basis of coordinating the horizontal and vertical position adjustment, the lifting is achieved by the extension and retraction of the hanging rope of the first hanging wire mechanism.

[0035] The second hanger 6 is embedded in the first hanger 5. The second hanger 6 is provided with a second adjustment seat 601 connected to the transmission end of the third motor 501 and a second suspension wire mechanism for lifting. The second adjustment seat 601 can longitudinally unfold and store the second hanger 6 through the transmission cooperation of the third motor 501. The second adjustment seat 601 is provided with a second rotating disk 603 for adjusting the lateral angle of the second hanger 6 and a fifth motor 602 for driving the second rotating disk 603;

[0036] Furthermore, the second hanger 6 is an auxiliary hanger, which is hidden and stored in the first hanger 5. When the first hanger 5 is assisted in lifting or multiple and different types of objects are lifted separately, the second hanger 6 can be unfolded, that is, the second adjustment seat 601 is longitudinally adjusted by the third motor 501, so as to realize the unfolding and storage of the second hanger 6. At the same time, the second adjustment seat 601 has a lateral offset adjustment function based on the longitudinal expansion position adjustment, and the lateral position of the second hanger 6 is changed according to the specific situation to accurately adjust its lifting position;

[0037] In summary, the balancing crane adopts a double-frame combination structure, that is, a combination of a main hanger and an auxiliary hanger. When facing a large object and the main hanger cannot achieve the best lifting effect, and when facing multiple and different types of objects to be lifted separately, that is, the main hanger cannot complete the lifting independently, facing the above situation, the main hanger and the auxiliary hanger of the balancing crane can cooperate with each other to solve the problem.

[0038] The second hanger 6 on the balance crane is used as an auxiliary hanger. When it is idle, it can be stored and hidden in the first hanger 5 to achieve a hidden effect, which will not affect the normal use of the first hanger 5. At the same time, in order to achieve the best auxiliary lifting effect, the second hanger 6 can adjust its longitudinal position during the deployment. The second hanger 6 can adjust its longitudinal position by adjusting the second adjustment seat 601. The upper adjustment component can also be used to fine-tune the angle on both sides, that is, lateral position adjustment, while the second hanger 6 realizes longitudinal position adjustment, which provides certain convenience for auxiliary lifting of the first hanger 5 or different types of independent lifting.

[0039] The specific uses of this balance crane include:

[0040] According to the specific use scenario, the cylinder 1 drives the entire hanger to move within the lifting range. If the lifting can be completed by the first hanger 5, during the lifting process, the first motor 303 on the main adjustment member 3 can drive the first rotating disk 302 to rotate to adjust the horizontal position of the entire hanger, and at the same time cooperate with the second motor 402 on the main frame 4 to drive the longitudinal position adjustment of the main hanger, so as to accurately adjust the lifting position of the main hanger. During lifting, the fourth motor 503 drives the wire roller 7 inside the first wire drum 502 to release and reel in the wire, and lifting can be achieved by hanging the object;

[0041] If the auxiliary hanger is needed, the third motor 501 on the main hanger drives the auxiliary hanger to rotate longitudinally toward the bottom of the main hanger. According to the specific lifting position of the object, the fifth motor 602 on the second adjusting seat 601 drives the second rotating disk 603, so that the auxiliary hanger is offset to both sides of the main hanger until the optimal lifting position is reached. The sixth motor 606 drives the wire roller 7 in the second wire drum 604 to release the wire. By cooperating with the main hanger and fixing it, and performing synchronous lifting, the lifting of large objects can be achieved. When performing independent lifting of different types of objects, different types of objects are hung on the hooks on the main hanger and the auxiliary hanger. By offsetting the two sides of the auxiliary hanger, the objects on the main hanger can be effectively classified during unloading. After use, the auxiliary hanger is reset and stored in the main hanger.

[0042] It should be noted that based on the double-frame combination structure of the balance crane, multiple frames for auxiliary lifting can be placed on the main hanger according to the application scenario of the main hanger. Based on the double-frame combination structure, the functionality and practicality of the balance crane can be further improved.

[0043] In order to adjust the position of the entire hanger, the specific Figure 1 and Figure 2 The main adjusting member 3 is described as follows. The main adjusting member 3 includes a first adjusting seat 301, a first rotating disk 302 and a first motor 303. The first adjusting seat 301 is provided with a semi-closed groove for engaging the first rotating disk 302. The first motor 303 is arranged on the top of the first adjusting seat 301 and the transmission end passes through the first adjusting seat 301 and is connected to the first rotating disk 302.

[0044] Specifically, the main adjusting member 3 mainly drives the first rotating disk 302 embedded on the first adjusting seat 301 to rotate through the first motor 303, so that the main frame 4 connected to the first rotating disk 302 and the two sets of hangers connected to the main frame 4 can be adjusted in the overall lateral position;

[0045] The first hanging wire mechanism is a lifting component of the first hanging bracket 5, such as Figure 1 , Figure 2 and Figure 3As shown, the first wire hanging mechanism is described as follows. The first wire hanging mechanism includes a first wire hanging drum 502, a fourth motor 503 and a first connecting disk 504. The first wire hanging drum 502 is arranged on the first connecting disk 504, and the first connecting disk 504 is fixed on the first hanger 5. The fourth motor 503 is arranged on one side of the first wire hanging drum 502, and is used to control the extension and retraction of the wire in the first wire hanging drum 502. The first wire hanging mechanism mainly drives the wire roller 7 in the first wire hanging drum 502 to rotate through the fourth motor 503, so as to achieve the effect of winding and releasing the wire.

[0046] In order to ensure the balance of the lifting after the second hanger 6 is adjusted based on different positions, such as Figure 2 and Figure 4 As shown, the second wire hanging mechanism includes a second wire hanging drum 604, a transmission seat 605, a sixth motor 606 and a second connecting plate 607. The second wire hanging drum 604 and the first wire hanging drum 502 are both provided with a wire roller 7 wound with a wire. The second wire hanging drum 604 is provided on the second connecting plate 607, and the second connecting plate 607 is rotatably connected to the second hanger 6.

[0047] Based on the second suspension wire mechanism, further described, Figure 2 and Figure 4 As shown, in order to adapt to the balance effect of the second hanger 6 during the position adjustment process, the force and the lifting process, especially when the second hanger 6 moves laterally based on the two sides of the first hanger 5, during the rotation process, under the influence of gravity, the second connecting plate 607 of the rotating structure will adaptively adjust the position of the second hanging wire drum 604 to make it in the best position, thereby effectively avoiding the phenomenon of hard pulling caused by position deviation between the hanging rope and the hanging wire drum;

[0048] Since the space inside the first hanger 5 is limited, in order to achieve the best storage effect for the second hanger 6, as shown in FIG. Figure 4 and Figure 5 As shown, the transmission seat 605 is arranged on one side of the second wire drum 604 and is connected to the second wire drum 604. One end of the transmission seat 605 extends to the top side of the second wire drum 604. Two sets of gears 608 meshing with each other are arranged inside the transmission seat 605. The sixth motor 606 is arranged on the top of the second wire drum 604, and the transmission end of the sixth motor 606 is connected to one of the two sets of gears 608 for transmission of the gear 608. The other set of the two sets of gears 608 is connected to the wire roller 7 inside the second wire drum 604.

[0049] Specifically, the sixth motor 606 for driving the second wire hanging drum 604 is arranged at the top of the drum body, and the wire roller 7 in the second wire hanging drum 604 is driven by the cooperation of the two sets of gears 608 in the transmission seat 605. In this way, the lateral area of ​​the second wire hanging mechanism is maximized, and the transmission of the wire roller 7 is also realized, so that the storage and deployment of the second hanging frame 6 will not be affected;

[0050] It should be noted that hooks are provided at the ends of the wires on the wire rollers 7 inside the first wire drum 502 and the second wire drum 604, and the two sets of gears 608 are of the same size. Gears 608 of the same size ensure synchronization of transmission and consistency of transmission frequency.
