[0003] In reality, a maintenance platform that can run randomly cannot be made for a single-girder crane. Generally, the maintenance platform of a single-girder crane is set at a fixed position in the workshop. During normal daily maintenance, the crane is driven to the fixed platform for maintenance. If the crane breaks down and stays at a position far from the platform, maintenance personnel cannot use the fixed maintenance platform to troubleshoot the problem, which is inconvenient to use.

[0004] The parts of the crane that need to be repaired are generally more than 6m above the ground. At this time, a truck crane or a hydraulic lifting platform can also be used to send maintenance personnel to the fault point. However, due to equipment or foundation pits on the ground in some special workshops, the truck crane or the hydraulic lifting platform cannot reach below the crane, making it impossible to carry out fault repair, which is inconvenient to use. Therefore, the utility model proposes a mobile maintenance platform for single-girder cranes to solve the problems existing in the prior art. Content of the Utility Model

[0022] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0023] According to Figures 1-6 as described above, this embodiment proposes a mobile maintenance platform for a single-girder crane, including a platform housing. The platform housing includes a top plate 1 and load-bearing columns 2, that is, the platform housing is composed of the top plate 1 and load-bearing columns 2. Specifically, load-bearing columns 2 are installed below the top plate 1, and four groups of load-bearing columns 2 are evenly provided. The load-bearing columns 2 are evenly distributed at the four corners of the top plate 1. Reinforcing components are installed on both sides below the platform housing. A load-bearing plate 3 is provided above the reinforcing components, and the load-bearing plate 3 is fixedly connected to the corresponding load-bearing column 2. As Figure 1 shown, load-bearing plates 3 are provided on both sides below the top plate 1, that is, two groups of load-bearing plates 3 are provided. The load-bearing plates 3 are used to carry staff to stand and move on them. In order to enhance the load-bearing performance of the load-bearing plates 3 themselves, therefore, reinforcing components are provided below the load-bearing plates 3 in this device.

[0024] Specifically, as Figure 1As shown in the figure, the strengthening component includes a strengthening plate 11. Above the strengthening plate 11, it is connected to the load-bearing plate 3 through support bars 12. There are several groups of support bars 12. In this embodiment, there are two groups of support bars 12 above each group of strengthening plates 11. A connecting plate 13 is installed above the strengthening plate 11, and the connecting plate 13 is connected to the corresponding load-bearing columns 2 (for example, both ends of the left connecting plate 13 are fixedly connected to the two left load-bearing columns 2). Thus, through the cooperation of the strengthening plate 11, the support bars 12, and the connecting plate 13, the connection relationship between the load-bearing plate 3 and the load-bearing columns 2 is ensured to guarantee the load-bearing performance.

[0025] There are bayonets 14 on the load-bearing plate 3. A relay pedal 15 is provided between the two load-bearing plates 3 on both sides. Both ends of the relay pedal 15 respectively extend into the bayonets 14 at the corresponding positions and are connected to the load-bearing plate 3 through bolts. Thus, the two load-bearing plates 3 on both sides form an integral whole, and the relay pedal 15 is in a detachable state. When the device needs to be disassembled, the relay pedal 15 is disassembled, which then facilitates the subsequent disassembly operation. When it is not necessary to disassemble, the relay pedal 15 is installed at the established position to increase the standing space for the staff and facilitate their operation.

[0026] Two symmetrically arranged ladders 4 are installed above the load-bearing plate 3, and the ladders 4 are fixedly connected to the load-bearing columns 2. In this embodiment, the ladders 4 are located at the ends of the load-bearing plate 3. Therefore, inside the platform outer shell, a blocking effect is formed to ensure the safety of the staff. And when the staff enters or exits, it can play the role of climbing up and down. The specific structure of the ladders 4 Figure 3 As shown in the figure, it is a schematic diagram of two ladders 4 (on different sides). After they are respectively fixedly connected to the load-bearing columns 2 at the corresponding positions, they have a complete climbing up and down effect.

[0027] A traveling drive axle 5 is installed below the top plate 1, and several groups of traveling drive axles 5 are evenly provided. In this embodiment, two groups of traveling drive axles 5 are evenly provided, as Figure 2 and Figure 5 shown. The traveling drive axle 5 includes a main shaft 17. Both ends of the main shaft 17 are connected to the top plate 1 through axle brackets 18. A traveling wheel 19 is installed on the main shaft 17, and several groups of traveling wheels 19 are provided. In this embodiment, two groups of traveling wheels 19 are installed on each main shaft 17. At the same time, a pulley is installed on the main shaft 17, and the traveling drive axle 5 is driven by a belt motor 7, as Figure 1As shown in the figure, the belt motor 7 is installed above the top plate 1 and connected to the top plate 1 through a bracket. The output end of the belt motor 7 is connected to the belt pulley through a belt. Thus, when the belt motor 7 works, it drives the belt pulley to rotate through the belt, and then drives the main shaft 17 to rotate. Thereby, the walking wheel 19 starts to rotate. During operation, the lower end surface of the walking wheel 19 contacts the main beam 21 of the single-girder crane. Thus, when the walking wheel 19 rotates above it, its position will change, and thereby the position of the top plate 1 changes. Correspondingly, when the crane stays in a non-maintenance area due to a fault, the staff enters this maintenance platform, and then uses the controller (this device has a general controller to control all the electronic components in this device) to control the belt motor 7 to work. Thus, the maintenance platform can be operated to move along the crane main beam, and then reach any fault point on the crane for maintenance.

[0028] On both sides below the top plate 1, side plates 6 are installed, and a horizontal component is installed on the side plates 6. The two ends of the side plates 6 are also fixedly connected to the corresponding load-bearing columns 2. Specifically, the horizontal component includes a horizontal support frame 8, and there are several groups of horizontal support frames 8, such as Figure 2 As shown in the figure, in this embodiment, on each group of side plates 6, five groups of horizontal support frames 8 are installed. One end of the horizontal support frame 8 is fixedly connected to the side plate 6, and a horizontal wheel 9 is installed at the other end of the horizontal support frame 8. When this device is installed on the main beam 21, the horizontal wheel 9 contacts the side surface of the main beam 21. Specifically, safety rods 10 are installed between the five groups of horizontal support frames 8 on each side, that is, there are four groups of installation rods 10 on each side. The main function of the installation rod 10 is to facilitate the staff to hang the rope hook of the installation rope on the installation rod 10.

[0029] At the same time, a limit seat 16 is provided below the top plate 1, and there are several groups of limit seats 16 evenly. In this embodiment, there are two groups of limit seats 16. At the same time, a limit opening is provided inside the limit seat 16, and the limit seat 16 is connected to the top plate 1 through a fixing block. Its working state is as Figure 4 shown. The limit seat 16 fits the upper part of the main beam 21 and is in frictional contact with it. Further, it cooperates with the horizontal wheel 9 to ensure the stability of this platform during movement, and there will be no shaking during the normal operation and fault maintenance of the crane.

[0030] On both sides of the platform housing, guardrails 20 are installed. There are several groups of guardrails 20, and the two ends of the guardrails 20 are respectively connected to the corresponding load-bearing columns 2. In this embodiment, there are three groups of guardrails 20 on each side from top to bottom in sequence. Its main function is to play a role in protection and interception, improving the safety of the staff.
