[0037] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific diagrams. It should be noted that the terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described here can be implemented in an order other than that illustrated or described here. In addition, the term "including" or "having" and any variation thereof are intended to cover non-exclusive inclusions, for example, a product or device containing a series of components or units is not necessarily limited to those components or units clearly listed, but may include other components or components that are not clearly listed or inherent to these products or devices.

[0038] The utility model of the operating platform omnidirectional adjustment device comprises a chassis assembly and an adjustment operation assembly, wherein the chassis assembly is used to install and fix the operating platform omnidirectional adjustment device on a fixed foundation of the port lifting equipment operating room, such as the bottom plate of the operating room or the bottom bracket of the operating room. The chassis assembly has a fixed fixed plate (i.e., a combination structure of a middle plate and a lower plate hereinafter) and a movable plate (i.e., an upper plate hereinafter) rotatable relative to the fixed plate, and the movable plate is rotatably connected to the fixed plate;

[0039] The adjusting operation component is used to rotate the movable plate therein after manually adjusting the chassis component. The adjusting operation component is arranged on the chassis component and has a rotation control mechanism that allows the movable plate to rotate freely relative to the fixed plate.

[0040] The utility model can be configured as follows to realize the chassis assembly: In some embodiments, as Figure 1 , Figure 2 , Figure 3 As shown, the chassis assembly includes an upper chassis 101, a middle chassis 102 and a lower chassis 103. The lower chassis 103 is fixed on a fixed foundation of the port lifting equipment operation room; the middle chassis 102 is downwardly connected to the lower chassis 103, and the two are fixedly connected; the upper chassis 101 is downwardly connected to the middle chassis 102, and the two are rotatably connected;

[0041] The middle plate 102 is in the shape of a disk, and a friction block 300 is provided on its outer ring surface. The adjustment operation component has a pressure block 201 that cooperates with the friction block 300. The pressure block 201 is extended and retracted after being operated by the rotation control mechanism, and the extension direction is the up and down direction. When it is extended downward until it contacts the friction block 300, the two generate resistance to stop the upper plate 101 relative to the middle plate 102, thereby realizing the positioning of the upper plate 101.

[0042] In order to realize the rotation connection between the upper plate and the middle plate, the utility model can be arranged as follows: In some embodiments, Figure 4 As shown, a through hole structure is provided at the center of the disk surface of the upper disk 101, and a rotating shaft 104 is fixedly provided on the upper disk surface of the middle disk 102. The rotating shaft 104 passes through the through hole structure of the upper disk 101 upwards to realize relative rotation between the two.

[0043] It should be noted that the middle plate 102 and the rotating shaft 104 are concentric circles, and the height dimension of the rotating shaft 104 can be set shorter, and its function is only to support the low-speed rotation of the upper plate relative to the middle plate (when omnidirectionally adjusted). In addition, the diameter of the rotating shaft can be set larger to ensure smooth rotation.

[0044] In order to ensure smooth rotation of the shaft, the utility model can be configured as follows: In some embodiments, Figure 4 As shown, the through hole structure of the upper plate 101 is located on the upper plate surface of the upper plate 101. The opening is a countersunk hole structure, which has an upper hole and a lower hole. The two holes are connected. The upper hole is connected to the upper plate surface of the upper plate 101, and the lower hole is connected to the lower plate surface of the upper plate 101.

[0045] Corresponding to the through-hole structure of the upper plate 101, the rotating shaft 104 includes an upper end cover portion and a lower main body portion, which are integrally formed. The main body portion is located in the lower hole, and the end cover portion is located in the upper hole. The cross-sectional diameter of the end cover portion is larger than the cross-sectional diameter of the lower hole and smaller than the cross-sectional diameter of the upper hole, and the cross-sectional diameter of the main body portion is smaller than the cross-sectional diameter of the lower hole.

[0046] It should be noted that, in order to facilitate the connection between the rotating shaft and the middle disk, a fastening hole can be set on the middle disk, and another corresponding fastening hole can be set on the rotating shaft, and the two are connected by a fastener 105. The fastening holes here are only used to connect the rotating shaft 104 and the middle disk 102 so that the two are relatively fixed. Therefore, when reinforcement is required, multiple fastening hole groups can be set on the rotating shaft and the middle disk. In addition, the fastening holes on the rotating shaft 104 are through hole structures, and the fastening holes on the middle disk are through holes or blind holes. In order to make the upper disk surface of the upper disk 101 flat, the fastening holes on the rotating shaft 104 can be set as countersunk holes, so that the ends of the fasteners fall into the upper part of the countersunk holes to prevent them from being exposed on the upper disk surface of the upper disk 101.

[0047] Based on this example, in some preferred embodiments, in order to better achieve smooth rotation and provide comfort during angle adjustment, the following structure can be set: Figure 4 As shown, a shaft sleeve 106 is sleeved on the rotating shaft 104, and the shaft sleeve 106 is located between the main body and the lower hole.

[0048] The utility model increases the smoothness of rotation of the rotating shaft when the rotating shaft exerts a rotating effect through the shaft sleeve, and also reduces the wear of the outer wall of the rotating shaft body and the wear of the inner wall of the through-hole structure of the upper plate.

[0049] In some preferred embodiments, in order to achieve better stability during rotation and provide comfort during angle adjustment, the following structure can be used: Figure 4 As shown, a plane bearing 107 is provided at the connection between the upper hole and the lower hole of the through hole structure of the upper plate 101, so that the end cover part of the rotating shaft 104 is mounted on the plane bearing 107, which increases the rotation smoothness when it rotates, and also reduces the wear of the device during rotation (here refers to the wear caused by the friction between the part of the end cover part exposed outside the main body and the step surface at the connection between the upper hole and the lower hole).

[0050] In order to prevent the friction block from falling off after being arranged on the middle plate, the utility model can be arranged according to the following structure: Figure 2 , Figure 3 As shown, in some embodiments, the outer ring surface of the middle plate 102 is provided with a recessed structure, which surrounds the outer ring surface of the middle plate 102 for a circle and then closes to form an embedding groove, so as to facilitate embedding of the friction block 300 so that it is not easy to fall off after installation.

[0051] Based on this example, in some embodiments, the friction block 300 is a friction block with an annular structure, which surrounds the outer annular surface of the middle plate 102 for one circle and then closes.

[0052] In some preferred embodiments, the cross section of the friction block 300 is circular, so that the part embedded in the embedded groove and the outer convex structure are both arc-shaped (herein, in the structure shown in the figure, the part embedded in the embedded groove and the opposite outer convex part in the cross section of the friction block are arc-shaped). When embedded, the adhesion is increased, and when convex, Figure 2 , Figure 3 In the structure shown, when the pressing block 201 is pressed down to contact the surface of the friction block 300, the contact mode is point contact (the point contact here is only for the convenience of explanation based on the illustrated structure. In actual contact, the contact part is an arc around the outer surface of the friction block. As described later, when using Figure 6 When the semicircular ring structure is pressed, the initial contact shape of the friction block is semicircular, and gradually increases with the pressure to surface contact, thereby gradually increasing the friction resistance. This structural coordination can increase the comfort during the rotation operation, avoid the feeling of frustration during the braking process that affects the comfort, and also avoid indirectly increasing the fatigue of the operator.

[0053] In some preferred embodiments, Figure 6 As shown (the figure hides the rest of the adjustment operating component), the pressure block 201 of the utility model can be set as a semi-circular ring structure to correspond to the shape of the friction block. When it is pressed down after being driven by the spring of the adjustment operating component, the contact area with the friction block is increased, thereby achieving a smoother and better braking effect.

[0054] In order to realize the adjustment operation and increase the convenience of operation, the utility model can set the adjustment operation component according to the following structure: In some embodiments, such as Figure 2 , Figure 3 , Figure 5 As shown, the adjustment operation component includes a pedal 202, a pedal connecting rod 203, a shell member 204, and a spring 205, wherein the pedal connecting rod 203 is rotatably connected to the shell member 204, and the pedal 202 is arranged at one end of the pedal connecting rod 203, so that the operator can rotate the pedal connecting rod 203 around the rotation connection point between the pedal connecting rod 203 and the shell member 204 after stepping on the pedal, and the other end of the pedal connecting rod 203 is connected to the pressure block 201; the spring 205 is connected to one end of the pedal connecting rod 203 connected to the pressure block 201 through a connecting rod mechanism (i.e., the pressure block connecting rod hereinafter); the shell member 204 is connected to the upper plate 101, and encapsulates part of the structure of the pressure block 201 and the pedal connecting rod 203 therein, which has the effect of dust and moisture proof, and is also convenient for extending the service life of the lubricant after applying lubricants such as butter to the rotating connection position; the upper plate 101 is provided with a through hole for facilitating the vertical extension and retraction of the pressure block 201.

[0055] It should be noted that the rotational connection between the pedal connecting rod 203 and the housing member 204 can be achieved by providing a rotating shaft in the inner cavity of the housing member 204, such as Figure 5 As shown, under this structural setting, the rotating shaft 206 is placed horizontally in the shell part 204 (the viewing direction in the figure is along the axial direction of the rotating shaft), and the two ends are rotationally connected to the opposite side walls of the shell part 204, and the rotating shaft 206 passes through the rod of the pedal connecting rod 203 located in the shell part 204.

[0056] Figure 1 The structure shown hides the shell 204 and shows the connection structure of the rotating shaft 206 . After bearings 209 are respectively arranged at both ends of the rotating shaft 206 , the rotating shaft is supported for rotation. The bearings 209 can be arranged in the side wall of the shell 204 .

[0057] When the adjustment operation component is set in the utility model, the rotating connection position is encapsulated in the shell part. After the shell part is opened, an action gap is reserved for the swing of the pedal connecting rod. The spring is connected to the end of the pedal connecting rod connected to the end of the pressure block, and a downward force is applied to the end. That is to say, when no external force is applied manually, the contact between the pressure block and the friction block is achieved through the spring. After the external force is applied, the pedal connecting rod lifts the pressure block upward and also presses the spring upward.

[0058] In this example, the spring is directly connected to the pressure block through a linkage mechanism, and the pressure block is connected to the end of the pedal linkage.

[0059] In some embodiments, such as Figure 5As shown, the spring 205 is arranged in a spring box 207, the upper end of the spring 205 is fixedly connected to the top of the spring box 207, and the bottom of the spring 205 is connected to the end of the pedal connecting rod 203 through a pressure block connecting rod 208.

[0060] In other preferred embodiments, in order to make the spring have a better control effect on the pressure block, the following structure can be set: Figure 5 A spring 205 is arranged in the spring box 207, and the upper and lower ends of the spring 205 are respectively connected to the top and bottom of the spring box 207, and the pressure block connecting rod 208 is connected to the middle part of the spring 205. When the spring is not under force, the pressure block 201 is pressed downward (when connecting and adjusting the spring and the pressure block here, the spring can be squeezed upward first, and then the pressure block connecting rod is installed to the pressure block. When the spring is released, its restoring force presses the pressure block connecting rod downward and then drives the pressure block downward).

[0061] It should be noted that after the implementation of the utility model, when no operation or adjustment is performed by the operator, the pressure block and the friction block generate resistance after contacting each other, so that the upper plate of the chassis assembly is fixed in a specific position; when operation and adjustment rotation are required, the operator steps on the pedal to separate the pressure block and the friction block so that the upper plate can rotate freely relative to the middle plate. At this time, the spring is compressed to one side. When it is rotated to the required angle, after releasing the pedal, the restoring force of the spring presses the pedal connecting rod and the pressure block downward, so that the pressure block contacts and squeezes the friction block, thereby stopping the rotation trend, positioning the upper plate, and completing the adjustment operation.

[0062] In order to facilitate the vertical expansion and contraction of the pressing block, a sleeve structure (not shown in the figure) can be arranged on the pressing block to avoid friction with the through hole on the upper plate and accelerated wear during expansion and contraction. At the same time, the sleeve structure can also provide a certain guiding effect for the vertical expansion and contraction of the pressing block.

[0063] The utility model is convenient for installing load-bearing structures such as seats and operating gear handles, such as Figure 1 As shown, the upper plate 101 may be provided with a mounting hole 1001, so that it is located on the upper plate surface of the upper plate 101. The connection and fixation between the lower plate and the mounting base may be achieved by welding or fastener connection.

[0064] In summary, the utility model realizes omnidirectional rotational free adjustment through the matching structure of the upper plate and the lower plate and fixes the base on the installation basis, and the friction block and the pedal operation assembly realize manual control of the rotation adjustment angle and stop positioning. The structure configuration is simple, easy to manufacture, easy to operate, and the adjustment is fast and free to position. It is especially suitable for the linkage operating table of port lifting and hoisting equipment.

[0065] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
