Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0034] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "front," "back," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] like Figures 1-5 As shown in the attached figures, the X direction is the first direction, the Y direction is the second direction, and the Z direction is the vertical direction. This application provides a hydraulic arm adjusting device 100. The hydraulic arm is mounted on a slide rail via the hydraulic arm adjusting device 100. The hydraulic arm adjusting device 100 includes a fixing member 10 and a connecting member 20. The fixing member 10 includes a fixing part 11, a first connecting part 12, and a second connecting part 13. The fixing part 11 is connected to the movable block of the slide rail. The first connecting part 12 extends along a first direction, and the second connecting part 13 extends along a second direction. The first and second directions intersect.

[0036] The connector 20 is connected to the fixing member 10 and the hydraulic arm respectively. The connector 20 includes a third connecting part 21 and a fourth connecting part 22. The third connecting part 21 extends along a first direction and is arranged with the first connecting part 12 along a second direction. The fourth connecting part 22 extends along a second direction and is arranged with the second connecting part 13 along a second direction. The distance between the first connecting part 12 and the third connecting part 21 is adjustable, and the distance between the second connecting part 13 and the fourth connecting part 22 is adjustable, so that the position of the hydraulic arm is adjustable in the first direction and the second direction.

[0037] Here, it can be understood that the fixing part 11 is used to install the fixing member 10 on the slide rail. When the movable block slides up and down, it drives the hydraulic arm adjusting device 100 to slide up and down, thereby driving the hydraulic arm to slide up and down, realizing the lifting and lowering of the hydraulic arm. The first connecting part 12 and the second connecting part 13 extend in two directions respectively, and the third connecting part 21 and the fourth connecting part 22 correspond to the first connecting part 12 and the second connecting part 13 of the fixing member 10 respectively. The distance between the third connecting part 21 and the first connecting part 12 is adjustable, and the distance between the fourth connecting part 22 and the second connecting part 13 is adjustable, so that the hydraulic arm can obtain adjustable space in two directions.

[0038] When the hydraulic arm experiences positional deviation due to prolonged use, causing the cylinder head to fall out of position, if the deviation occurs in the second direction, the hydraulic arm can be adjusted in the second direction by adjusting the distance between the first connecting part 12 and the third connecting part 21. If the deviation occurs in the first direction, the hydraulic arm can be adjusted in the first direction by adjusting the distance between the second connecting part 13 and the fourth connecting part 22.

[0039] This embodiment of the application provides a hydraulic arm adjustment device 100 between the hydraulic arm and the guide rail. The connecting member 20 can be adjusted in two directions relative to the fixing member 10, thereby realizing the adjustment of the hydraulic arm's position in the forward and backward and left and right directions perpendicular to the lifting direction. This can correct the positional error of the hydraulic arm during operation and improve the positional accuracy of the hydraulic arm.

[0040] This embodiment achieves secondary position correction of the hydraulic arm perpendicular to the lifting direction. Compared with the traditional fixed installation method using guide rails, it eliminates post-installation positional errors without disassembly and reinstallation. Furthermore, it eliminates the need for manual pushing of the cylinder head back to the designated position and avoids the expense of replacing a high-precision hydraulic lifting arm. Simple adjustments are all that's required to accurately lower the cylinder head to the designated position, ensuring proper locking of the chuck. This approach offers high adjustment efficiency and low cost.

[0041] In actual operation, when the hydraulic arm structural components undergo slight deformation due to stress, causing the slider to jam, the bidirectional adjustment of the hydraulic arm adjustment device 100 can immediately compensate for the deformation, making the slider run more smoothly. Once the hydraulic arm structural components deform, they cannot be compensated for immediately, resulting in a high frequency of slider jamming.

[0042] In some embodiments, the fixing part 11 is provided with a connecting hole for connecting the movable block.

[0043] In some embodiments, the hydraulic arm adjusting device 100 may further include an adjusting mechanism 30 disposed between the fixing member 10 and the connecting member 20. The adjusting mechanism 30 includes a plurality of first adjusting members 31 and a plurality of second adjusting members 32. The first adjusting members 31 extend along a second direction and are used to adjust the distance between the first connecting portion 12 and the third connecting portion 21. The second adjusting members 32 extend along a first direction and are used to adjust the distance between the second connecting portion 13 and the fourth connecting portion 22.

[0044] This can be understood as follows: adjusting the first adjusting member 31 changes the distance between the first connecting part 12 and the third connecting part 21, thereby causing the hydraulic arm to move in the second direction. Adjusting the second adjusting member 32 changes the distance between the second connecting part 13 and the fourth connecting part 22, thereby causing the hydraulic arm to move in the first direction. This allows the positional deviation of the hydraulic arm to be converted into a specific mechanical length adjustment, achieving precise control.

[0045] Operators can make corrections simply by adjusting the adjustment parts in the corresponding direction, which replaces the tedious operation of manually pushing the cylinder head and avoids the trouble of disassembling and reassembling the hydraulic arm.

[0046] The first adjusting member 31 and the second adjusting member 32 can respectively cope with structural deformation in different directions. When the hydraulic arm undergoes local deformation due to long-term use, it can be compensated in real time by adjusting specific adjusting members, which can greatly reduce the jamming rate, extend the service life of the hydraulic arm, and reduce high replacement costs.

[0047] In some embodiments, see Figure 1 The first adjusting member 31 and the second adjusting member 32 are each in pairs. In other embodiments, the number of the first adjusting member 31 and the second adjusting member 32 can be set according to actual needs, for example, 3, 4, 5, 6, etc. The adjusting mechanism 30 can be directly integrated between the fixing member 10 and the connecting member 20 without requiring significant modification to the main structure of the original hydraulic arm and slide rail, thus having good practicality.

[0048] In some embodiments, both the first adjusting member 31 and the second adjusting member 32 can be adjusting bolts. The first connecting portion 12, the second connecting portion 13, the third connecting portion 21, and the fourth connecting portion 22 are each provided with an opening. The first adjusting member 31 passes through the opening, and its screw-in end abuts against the side of the third connecting portion 21. The distance between the first connecting portion 12 and the third connecting portion 21 is adjusted by adjusting the screw-in or screw-out of the first adjusting member 31. The second adjusting member 32 passes through the opening, and its screw-in end abuts against the side of the fourth connecting portion 22. The distance between the second connecting portion 13 and the fourth connecting portion 22 is adjusted by adjusting the screw-in or screw-out of the second adjusting member 32.

[0049] Here, the adjusting bolt has a helical drive characteristic; the screwing in or out of the adjusting bolt can be converted into a change in the relative position between the fixed part 10 and the connecting part 20. When it is necessary to adjust the distance in the second direction, rotating the first adjusting part 31 increases the length of the adjusting bolt when it is screwed in, which will push the third connecting part 21 to displace relative to the first connecting part 12. Screwing the adjusting bolt out can reduce the distance between the first connecting part 12 and the third connecting part 21. Similarly, adjusting the second adjusting part 32 in the first direction can change the relative position of the second connecting part 13 and the fourth connecting part 22 through a pushing action, ultimately realizing the position adjustment of the hydraulic arm in both the front-back and left-right directions.

[0050] The direction of rotation of the adjusting bolt is directly related to the direction of position change. Operators can easily adjust it using a simple wrench. The structure is simple and easy to operate, reducing the difficulty of adjusting the hydraulic arm position. The bolt pitch determines the adjustment amount per rotation, allowing for precise position correction and ensuring the cylinder head accurately returns to the locking position.

[0051] In some embodiments, both the first adjusting member 31 and the second adjusting member 32 can be telescopic rods. The first adjusting member 31 is disposed between the first connecting portion 12 and the third connecting portion 21. The second adjusting member 32 is disposed between the second connecting portion 13 and the fourth connecting portion 22.

[0052] Here, the telescopic rod can change its length by extending and retracting, thereby moving the third connecting part 21 or the fourth connecting part 22 connected to it. The telescopic rod's extension and retraction operation is simple and direct, with high adjustment efficiency, and its simple structure makes it easy to install and maintain.

[0053] When it is necessary to adjust the position of the hydraulic arm in the second direction, the length of the first adjusting member 31 can be adjusted to change the distance between the first connecting part 12 and the third connecting part 21, thereby adjusting the position of the hydraulic arm in the second direction. When it is necessary to adjust the position of the hydraulic arm in the first direction, the length of the second adjusting member 32 can be adjusted to change the distance between the second connecting part 13 and the fourth connecting part 22, thereby adjusting the position of the hydraulic arm in the first direction. In this way, by adjusting the length of the telescopic rod, the positional deviation of the hydraulic arm can be quickly eliminated, ensuring the stable operation of the hydraulic arm.

[0054] In some embodiments, the fastener 10 can be a T-shaped plate, with the fastening portion 11 extending along a first direction perpendicular to a second direction. Here, the fastening portion 11 extends in the same direction as the first connecting portion 12, forming the horizontal side of the T-shape. The second connecting portion 13 is perpendicular to the first connecting portion 12, forming the vertical side of the T-shape.

[0055] The T-plate has an integrated structure, which offers higher stability compared to dispersed connecting components, enabling it to reliably bear the operating load of the hydraulic arm. This concentrates the adjustment force, ensuring that adjustments in the first and second directions do not interfere with each other, and improving the accuracy of the adjustment direction.

[0056] The T-shaped structure concentrates the force points of the two adjustment directions on the same fixed part 11 through the vertically extending first connecting part 12 and second connecting part 13, eliminating the need for additional complex support structures and saving installation space for the hydraulic arm adjustment device 100.

[0057] In some embodiments, the adjusting member can be an L-shaped plate, with the third connecting portion 21 connected to the fourth connecting portion 22, and the end of the third connecting portion 21 away from the fourth connecting portion 22 connected to the hydraulic arm. Here, the connection of the third connecting portion 21 to the hydraulic arm allows positional changes of the connecting member 20 relative to the fixing member 10 to be transmitted to the hydraulic arm.

[0058] The third connecting part 21 and the fourth connecting part 22 are connected at right angles, which can be adapted to the T-shaped fixing part 10 structure and improve the accuracy of adjustment. The L-shaped plate has a simple structure and low cost, and can be quickly aligned with the fixing part 10 and the hydraulic arm during installation, making assembly easier and improving the assembly and maintenance efficiency of the hydraulic arm adjusting device 100.

[0059] In some embodiments, the first connecting part 12 and the third connecting part 21 can be connected by at least one first fastener 40. The first connecting part 12 and the third connecting part 21 are stably connected by the locking force of the first fastener 40, which can improve the structural stability of the hydraulic arm adjusting device 100. The first fastener 40 can effectively ensure the stability of the adjusted position, prevent the hydraulic arm from shaking or displacing during operation, and ensure the accuracy of the cylinder head repositioning.

[0060] In this embodiment, the movable and fixed states of the third connecting part 21 can be switched by loosening or tightening the first fastener 40, which is simple to operate. When adjusting the position of the hydraulic arm in the second direction, the first fastener 40 is loosened first to create a space for relative movement between the first connecting part 12 and the third connecting part 21. After the two are adjusted to a suitable distance by the first adjusting member 31, the first fastener 40 is tightened. Its axial force is used to stably fix the first connecting part 12 and the third connecting part 21, avoiding the position shift caused by vibration, load and other factors during the operation of the hydraulic arm, thereby maintaining the positional accuracy of the hydraulic arm in the second direction.

[0061] In some embodiments, the second connecting portion 13 and the fourth connecting portion 22 can be connected by at least one second fastener 50. The second connecting portion 13 and the fourth connecting portion 22 achieve a stable connection through the locking force of the second fastener 50, which can improve the structural stability of the hydraulic arm adjusting device 100. The second fastener 50 effectively ensures the stability of the adjusted position, prevents the hydraulic arm from shaking or shifting during operation, and ensures the accuracy of the cylinder head's repositioning.

[0062] In this embodiment, the movable and fixed states of the fourth connecting part 22 can be switched by tightening or loosening the second fastener 50, which is simple to operate. When adjusting the position of the hydraulic arm in the first direction, the second fastener 50 is first loosened to create a space for relative movement between the second connecting part 13 and the fourth connecting part 22. After the two are adjusted to a suitable distance by the second adjusting member 32, the second fastener 50 is tightened. Its axial force is used to stably fix the second connecting part 13 and the fourth connecting part 22, preventing the position from shifting again due to vibration, load and other factors during the operation of the hydraulic arm, thereby maintaining the positional accuracy of the hydraulic arm in the first direction.

[0063] The second fastener 50 cooperates with the first fastener 40 to achieve independent and stable fixation in two directions, which can improve the structural stability of the hydraulic arm adjustment device 100 and improve the practicality and reliability of the bidirectional adjustment of the hydraulic arm.

[0064] In some embodiments, the first connecting portion 12 and the third connecting portion 21 may be provided with a first mounting hole 60 for the first fastener 40 to pass through, and the first mounting hole 60 is an elongated hole. The second connecting portion 13 and the fourth connecting portion 22 may be provided with a second mounting hole 70 for the second fastener 50 to pass through, and the second mounting hole 70 is an elongated hole. Here, by reserving an adjustment margin in the length direction of the elongated hole, adjustment space is provided for the displacement of the connecting member 20 relative to the fixing member 10.

[0065] The allowance for the length of the elongated hole allows the connector 20 to slide within a certain range without completely disassembling the fasteners during adjustment. This simplifies the adjustment process and avoids efficiency losses and wear on parts caused by repeated disassembly.

[0066] When the position of the hydraulic arm needs to be adjusted in the first direction, the first fastener 40 can slide within the length range of the first mounting hole 60, cooperating with the action of the second adjusting member 32 to adjust the distance between the second connecting part 13 and the fourth connecting part 22. Similarly, the length direction of the second mounting hole 70 provides sliding space for adjustment in the second direction, ensuring that the connecting member 20 can move smoothly along the second direction. After the position is determined, it is locked by the second fastener 50, thereby stabilizing and fixing the adjusted position.

[0067] This application embodiment also provides a hoist, which includes a hydraulic arm, a slide rail, and the aforementioned hydraulic arm adjusting device 100. The slide rail includes a vertically extending guide rail and a movable block, the movable block being slidably connected to the guide rail. The hydraulic arm adjusting device 100 is connected to both the movable block and the hydraulic arm.

[0068] Here, the vertical guide rail provides guidance for the hydraulic arm to move up and down, and the hydraulic arm slides along the guide rail to realize the lifting and lowering of the cylinder head.

[0069] The hydraulic arm adjustment device 100 not only moves vertically in sync with the movable block, but also corrects the forward / backward and left / right positional deviations of the hydraulic arm perpendicular to the lifting direction in real time through its own bidirectional adjustment structure. When the hydraulic arm experiences axial or horizontal offset due to long-term use, or when it becomes jammed due to structural deformation, the adjustment device can change the spacing of the connecting parts to allow the hydraulic arm to accurately reset to the preset position without affecting the vertical movement, ensuring accurate docking with the locking chuck when the cylinder head falls back.

[0070] In the hoist of this application embodiment, the hydraulic arm is mounted on the slide rail via a hydraulic arm adjusting device 100, which includes a fixing member 10 and a connecting member 20. The fixing part 11 of the fixing member 10 is connected to the movable block of the slide rail. A first connecting part 12 extends along a first direction, and a second connecting part 13 extends along a second direction. The connecting member 20 is connected to both the fixing member 10 and the hydraulic arm. A third connecting part 21 of the connecting member 20 extends along the first direction, and a fourth connecting part 22 extends along the second direction. The distance between the first connecting part 12 and the third connecting part 21 is adjustable, and the distance between the second connecting part 13 and the fourth connecting part 22 is adjustable, thereby allowing the position of the hydraulic arm to be adjusted in both the first and second directions. The hydraulic arm adjusting device 100 of this application adjusts the relative position of the connecting member 20 and the fixing member 10 from two directions, realizing the forward / backward and left / right position adjustment of the hydraulic arm perpendicular to the lifting direction. This corrects the positional error of the hydraulic arm during operation and improves the positional accuracy of the hydraulic arm.

[0071] The hydraulic boom adjustment device 100 not only corrects initial position errors after installation but also compensates for structural deformation during long-term use in real time, reducing the probability of cylinder head misalignment and operational jamming, thus improving the stability of the hoist. Furthermore, it eliminates the need to replace the expensive hydraulic boom; the low-cost hydraulic boom adjustment device 100 suffices, and the adjustment operation can be completed while the hydraulic boom is running, without affecting production, thereby reducing maintenance costs and downtime losses.
