DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1, reference Figure 1 to Figure 2, which is the first embodiment of the present invention, provides a movable maintenance device, including a lifting frame 100, a connecting rod 101 is provided at the bottom end of the lifting frame 100, a locking wheel 102 is provided at the bottom end of the connecting rod 101, a storage component 103 is provided at the end of the connecting rod 101 away from the locking wheel 102, a locking component 104 is provided in the storage component 103, and the locking component 104 cooperates with the locking wheel 102 to control the locking state of the storage component 103.

[0029] Specifically, the storage assembly 103 includes a storage box 103a and a tool box 103b arranged on the connecting rod 101. The storage box 103a is used to place batteries and mobile power supplies, and the tool box 103b is used to place maintenance tools. The tool box 103b is provided with multiple groups. It should be noted that the tool box 103b allows the tools and equipment required for maintenance to be stored in an orderly manner, which is convenient for workers to quickly access and improves work efficiency. The storage box 103a is used to place batteries and mobile power supplies to provide the necessary energy support for maintenance work; the tool box 103b is used to place various maintenance tools. Its multiple group design can classify and store different types of tools, making tool management more efficient.

[0030] Furthermore, the tool box 103b includes a box body 103c and a box door 103d, and the box body 103c and the box door 103d are connected by hinges.

[0031] Example 2, reference Figures 2 to 3 This embodiment is different from the first embodiment in that a handle is fixedly connected to the side of the door 103d away from the box body 103c, and a locking block 103e is fixedly connected to the side of the door 103d close to the box body 103c.

[0032] Specifically, a locking assembly 104 is disposed in the box door 103d, and the locking assembly 104 is connected to the locking wheel 102 via a connecting rope.

[0033] Furthermore, the locking assembly 104 includes a telescopic rod 104a disposed at the bottom end of the box body 103c, a locking rod 104b disposed at the end of the telescopic rod 104a, and a spring disposed on the outer wall of the telescopic rod 104a.

[0034] It should be noted that a locking block 103e is fixedly connected to one side of the box door 103d close to the box body 103c. The locking block 103e works together with the locking assembly 104 in the box door 103d to fix the box door 103d and ensure the safety of the tools during transportation or movement. The locking block 103e cooperates with the locking assembly 104 and the locking wheel 102 to prevent the box door 103d from being accidentally opened, thereby avoiding the loss or damage of the tools.

[0035] The locking assembly 104 is connected to the locking wheel 102 through a connecting rope, which is a key mechanism for realizing automatic locking and unlocking of the tool box 103b. The setting of the locking assembly 104 makes the opening and closing state of the box door 103d associated with the moving state of the entire maintenance device, realizing intelligent locking control.

[0036] It should also be noted that the telescopic rod 104a can be extended and retracted under the action of the spring, while the locking rod 104b is adapted to the groove of the locking block 103e. When the inspection device is in working state, the locking plate of the locking wheel 102 is pressed down, and the telescopic rod 104a and the locking rod 104b are driven by the connecting rope, so that the locking rod 104b is disengaged from the groove of the locking block 103e, allowing the box door 103d to open. When the inspection device needs to be moved, the locking plate moves up, the telescopic rod 104a retracts under the action of the spring, and the locking rod 104b moves up to engage with the groove of the locking block 103e, and the box door 103d is locked to prevent the tool from falling during the movement.

[0037] The rest of the structure is the same as that of Example 1.

[0038] Example 3, reference Figures 1 to 4 This embodiment is different from the above embodiments in that one end of the connecting rope is fixedly connected to the bottom end of the locking rod 104b, and the other end of the connecting rope passes through the telescopic rod 104a, the bottom end of the box 103c, the connecting rod 101 and the locking plate end of the locking wheel 102 and is fixedly connected.

[0039] Specifically, a groove is formed at the bottom end of the locking block 103e, and the groove is matched with the locking rod 104b.

[0040] Furthermore, a cross bar 101a is provided at the end of the lifting frame 100, a slide rail is provided at the bottom end of the cross bar 101a, and an illumination lamp is provided on the cross bar 101a.

[0041] Furthermore, a lifting hook 101b is provided on the slide rail, and the lifting hook 101b can move along the slide rail.

[0042] It should be noted that one end of the connecting rope is fixedly connected to the bottom end of the locking rod 104b, and the other end passes through the telescopic rod 104a, the bottom end of the box body 103c, and the connecting rod 101, and is fixedly connected to the end of the locking plate of the locking wheel 102. This arrangement forms a linkage mechanism between the locking rod 104b and the locking wheel 102 through the connecting rope. When the locking plate of the locking wheel 102 is operated (such as pressing down or lifting up), the connecting rope will transmit this action to the locking rod 104b, thereby realizing the control of the locking state of the box door 103d. This mechanism allows the automatic switching of the locking and unlocking of the tool box 103b in different usage states (such as maintenance state and mobile state), thereby improving the convenience and safety of use.

[0043] The rest of the structure is the same as that of Example 2.

[0044] Operation process: The widest width of the maintenance lifting mobile work platform is 4.5 meters, which can lift heavy objects within 3 meters in width. The height is 3 meters and the side length is 2 meters. The top uses 200MM I-beams, on which the lifting points are installed. The two sides of the middle use φ80mm steel pipes and φ50mm steel pipes to form a triangular bracket for support. The bottom uses 160mm*130mm square steel with a thickness of 8mm as the foundation, and a rolling and locking wheel 102 is installed at the bottom. According to the load-bearing measurement, the mobile lifting device can lift 8 tons of objects. It is also equipped with an explosion-proof lighting system, an explosion-proof mobile power system and a maintenance tool box 103b.

[0045] After the successful design and manufacture of this device, it can effectively alleviate the problems of insufficient lifting devices, inconvenient lighting, and inconvenient movement of multiple tools during overhaul or maintenance of multiple equipment, and ensure the smooth progress of maintenance work. In addition, due to design problems, some equipment has no maintenance hanging points above it, and this device can also be used for maintenance, which is convenient for maintenance and ensures that there will be no personal equipment damage due to the lack of lifting devices during the maintenance process. When there is no maintenance task, it can be taken back to the warehouse, which will not increase the pressure of civilized production on site.

[0046] It should be noted that the present invention fixes and connects the tool box 103b and the storage box 103a at the end of the connecting rod 101. The tool box 103b is used to solve the problem of inconvenience in moving multiple tools, and the storage box 103a is used to place equipment such as explosion-proof mobile power supplies. It is worth noting that a spring, a telescopic rod 104a and a locking rod 104b are arranged in the tool box 103b, wherein the locking rod 104b is adapted to the groove of the locking block 103e. The purpose of such a setting is that when the maintenance device is in the maintenance working state, the locking plate of the locking wheel 102 is pressed down, so that the locking wheel 102 can no longer move. At this time, the whole device is in a locked state. When the locking plate is pressed down, the telescopic rod 104a is driven downward by the connecting rope. When the telescopic rod 104a moves downward, the locking rod 104b at its end moves downward at the same time. When the maintenance work is completed, the box door 103d is closed and the maintenance device is moved. When the maintenance device is in a moving state, the locking plate of the locking wheel 102 is pushed upward. When the end of the locking plate moves upward, the telescopic rod 104a moves upward at the same time under the action of the spring on the outer wall of the telescopic rod 104a. At this time, the locking rod 104b moves upward at the same time and engages with the groove of the locking block. At this time, the box door 103d is in a locked state. This arrangement allows the box door 103d to automatically switch between the locked and unlocked states according to the moving state of the maintenance device, which solves the problem of forgetting to lock the box door 103d during manual operation and causing tools to fall during the movement of the maintenance device.
