Description

Technical Field

[0001] This utility model relates to the field of port mobile machinery and equipment maintenance technology, specifically a lifting device for port mobile machinery and equipment maintenance. Background Technology

[0002] In port operations, port mobile machinery and equipment are used very frequently, and regular maintenance and upkeep are essential to ensure their normal operation.

[0003] Most existing lifting devices for port mobile machinery maintenance require the port mobile machinery to be placed on the lifting device. The usual operation involves manually or using other auxiliary equipment to move the port mobile machinery onto the lifting device's support plate. For example, Chinese patent application number 201920709986.8 discloses a support frame for machinery maintenance with lifting function. This patent includes a base and a lighting lamp. The lower end of the base is equipped with rollers and a hydraulic telescopic rod. The lower end of the auxiliary gear and the lower end of the main gear are slidably connected to the upper surface of the support platform, and a threaded rod passes through the auxiliary gear. The lower end of the threaded rod is rotatably connected to the upper surface of the support platform, and the upper end of the threaded rod passes through a fixed box. A fixing button is threaded onto the telescopic rod, and positioning blocks are provided at the inner ends of the telescopic rods on both sides. The lighting lamp is connected to the upper surface of the fixed box through a sliding groove, and the upper surface of the fixed box has drainage holes. The patented motor lowers the fixed box through the action of the rotating shaft, rotating rod, main gear, auxiliary gear and threaded rod, lifts the equipment onto the fixed box, and then raises the equipment to an appropriate height for maintenance. Lowering the fixed box reduces the time and effort spent on lifting the equipment.

[0004] Although the aforementioned patents elevate the equipment to a suitable height for maintenance and lower the fixed box to reduce the time and effort spent on lifting the equipment, in actual use, all of these patents require the mechanical equipment to be placed on the fixed box first. Due to the height difference between the fixed box and the ground, workers need to lift the mechanical equipment to a height higher than the fixed box before placing it on top of the box. Some mechanical equipment is equipped with casters at the bottom to facilitate handling and raise the equipment to a certain extent. However, the height difference of this patent is relatively large, so it still needs to be lifted. This method not only consumes a lot of manpower but also takes a long time to move, is inefficient, and poses certain safety hazards during the handling process, which can easily damage the equipment.

[0005] Therefore, a lifting device for the maintenance of mobile machinery and equipment in ports is needed to solve the above-mentioned problems. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a lifting device for the maintenance of port mobile machinery and equipment, which solves the problem that the excessive height difference between the machinery and the supporting mechanism on the lifting device leads to the time and effort required to place the machinery and equipment on the supporting mechanism, resulting in a long handling time and low efficiency.

[0010] In a preferred embodiment of this utility model, the adjusting mechanism includes a connecting frame, the rear side of which is fixedly connected to a lifting block and a slider respectively. The surface of the connecting frame is symmetrically provided with connecting grooves, and a moving strip is symmetrically fixedly connected inside the connecting groove. The surface of the bearing strip is symmetrically provided with moving grooves, and the moving grooves are slidably connected to the moving strip. A bidirectional electric slide rail is installed at the center of the connecting frame, and the two output ends of the bidirectional electric slide rail are fixedly connected to two bearing strips respectively.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, the present invention provides a lifting device for maintenance of port mobile machinery and equipment, including a support base 1. Universal wheels 2 are fixedly connected to the four corners of the bottom of the support base 1. A loading port 3 is opened on one side of the support base 1. A lifting mechanism 4 is fixedly connected to the top of the support base 1. A stabilizing mechanism 5 is symmetrically fixedly connected to the top of the support base 1 about the lifting mechanism 4. An adjusting mechanism 6 is provided at the output end of the lifting mechanism 4, and the adjusting mechanism 6 is located inside the loading port 3 and works in conjunction with it. An L-shaped support bar 7 is symmetrically provided at the output end of the adjusting mechanism 6. A battery and a controller are symmetrically fixedly connected to the top of the support base 1.

[0023] refer to Figure 2 and Figure 3 The lifting mechanism 4 includes a lifting bar 41, which is fixedly connected to the support base 1. A lifting groove is provided on the side of the lifting bar 41 near the loading port 3. A lifting column 42 is rotatably connected to the inside of the lifting groove through a bearing. A retractable protective sleeve is provided on the surface of the lifting column 42. A lifting motor 43 is fixedly connected to the bottom of the support base 1. A reducer 44 is fixedly connected to the output shaft of the lifting motor 43. The output shaft of the reducer 44 is fixedly connected to the lifting column 42 through a coupling. A lifting block 45 is threadedly connected to the surface of the lifting column 42. The outer side of the lifting block 45 is fixedly connected to the adjusting mechanism 6.

[0024] As a technical optimization of this utility model, the lifting bar 41 is fixed to the support base 1 to provide a stable installation foundation for the lifting mechanism 4. The lifting column 42 in the lifting groove is rotatably connected by bearings. After the lifting motor 43 transmits power through the reducer 44, the lifting column 42 rotates, and its surface thread cooperates with the lifting block 45 to realize the stable up and down movement of the lifting block 45 along the lifting bar 41, thereby driving the adjustment mechanism 6 to lift. This structure has stable transmission and can accurately control the lifting height to meet the height adjustment needs of different maintenance scenarios. Moreover, the reducer 44 can reduce the speed and increase the torque, making the lifting process more stable and reliable.

[0025] refer to Figure 3 The stabilizing mechanism 5 includes a support bar 51. A groove is provided on the side of the support bar 51 near the loading port 3. A sliding column 52 is fixedly connected inside the groove. A slider 53 is slidably connected to the surface of the sliding column 52, and the slider 53 is fixedly connected to the adjusting mechanism 6.

[0026] As a technical optimization of this utility model, the slider 53 slides on the surface of the slider 52 through the cooperation of the sliding groove on the support bar 51 and the sliding column 52. The slider 53 is fixed to the adjustment mechanism 6. When the adjustment mechanism 6 rises and falls with the lifting mechanism 4, the slider 53 slides on the sliding column 52, which plays a guiding and auxiliary support role, enhances the lateral stability of the adjustment mechanism 6 during the lifting process, prevents it from deviating or shaking during the lifting process, and ensures that the port mobile machinery equipment on the bearing bar 7 rises and falls smoothly.

[0027] refer to Figure 4 The adjusting mechanism 6 includes a connecting frame 61. The rear side of the connecting frame 61 is fixedly connected to the lifting block 45 and the slider 53 respectively. The surface of the connecting frame 61 is symmetrically provided with connecting grooves 62. The inside of the connecting grooves 62 is symmetrically fixedly connected with moving bars 63. The surface of the bearing bars 7 is symmetrically provided with moving grooves 64, and the moving grooves 64 are slidably connected with the moving bars 63. A bidirectional electric slide rail 65 is installed at the center of the connecting frame 61, and the two output ends of the bidirectional electric slide rail 65 are fixedly connected to the two bearing bars 7 respectively.

[0028] As a technical optimization of this utility model, the lifting block 45 and the slider 53 are connected by the connecting frame 61, which transmits the function of the lifting mechanism 4 and the stabilizing mechanism 5 to the adjusting mechanism 6. The connecting groove 62 and the moving bar 63 cooperate with the moving groove 64 on the bearing bar 7, so that the bearing bar 7 can slide along the moving bar 63 to realize the lateral adjustment of the position of the bearing bar 7. The bidirectional electric slide rail 65 can precisely control the movement of the two bearing bars 7. According to the size of the port mobile machinery and equipment, the spacing of the bearing bars 7 can be flexibly adjusted to better support the equipment, adapt to the bearing requirements of different specifications of equipment, and improve the flexibility and versatility of the device.

[0029] refer to Figure 1 and Figure 3 The top of the support base 1 is symmetrically threaded with a brake rod about the loading port 3. The bottom of the brake rod is fixedly connected with a brake block 8, and the brake block 8 is used in conjunction with the caster wheel 2. The top of the brake rod is fixedly connected with a rotating disk.

[0030] As a technical optimization of this utility model, the brake rod is threadedly connected to the support base 1. By rotating the rotating disk at the top of the brake rod, the brake rod can drive the brake block 8 to move up and down. When it is necessary to fix the lifting device, the rotating disk is rotated downwards, the brake block 8 descends and contacts the universal wheel 2 and applies pressure, restricting the rotation of the universal wheel 2, so as to realize the stable parking of the lifting device, prevent it from moving during maintenance, and ensure the safety and stability of maintenance work.

[0031] refer to Figure 1 and Figure 2The top of the support base 1 is symmetrically and fixedly connected with a counterweight box 9, and a storage drawer is provided on the outside of the counterweight box 9.

[0032] As a technical optimization of this utility model, a counterweight block can be added to the counterweight box 9 to adjust the overall center of gravity of the support base 1, thereby enhancing the stability of the lifting device. Especially when bearing heavy port mobile machinery and equipment, it prevents the device from tilting. The storage drawer on the outside of the counterweight box 9 can be used to store maintenance tools, parts, etc., making it convenient for maintenance personnel to access them, making the maintenance site more tidy and orderly, and improving the efficiency of maintenance work.

[0033] The working principle and usage process of this utility model are as follows: When using the lifting device for maintenance of port mobile machinery and equipment, firstly, the device is moved to the side of the port mobile machinery and equipment to be maintained by the universal wheels 2 at the bottom of the support base 1. The rotating disc at the top of the brake lever is rotated, causing the brake lever to drive the brake block 8 to descend, contact the universal wheels 2 and apply pressure to restrict the rotation of the universal wheels 2, thus securing the device in place. Then, the controller is started to control the operation of the lifting motor 43 in the lifting mechanism 4. After the output shaft of the lifting motor 43 reduces the speed and increases the torque through the reducer 44, it drives the lifting column 42 to rotate in the lifting groove of the lifting bar 41 through the coupling. Since the lifting column 42 is threadedly connected to the lifting block 45, the rotation of the lifting column 42 causes the lifting block 45 to move up and down along the lifting bar 41, thereby driving the adjustment mechanism 6, which is fixedly connected to the lifting block 45, to rise and fall. The rear side of the connecting frame 61 in the adjusting mechanism 6 is fixed to the lifting block 45 and the slider 53 in the stabilizing mechanism 5. During the lifting and lowering process of the adjusting mechanism 6, the slider 53 slides on the sliding column 52 of the support bar 51, playing a guiding and auxiliary support role, and enhancing the lateral stability of the adjusting mechanism 6 during lifting and lowering. When the adjusting mechanism 6 is lifted and lowered to a suitable height, the bidirectional electric slide rail 65 is controlled by the controller to run. The two output ends of the bidirectional electric slide rail 65 drive the two bearing bars 7 to slide along the moving bar 63 in the connecting groove 62 on the surface of the connecting frame 61. The spacing of the bearing bars 7 is adjusted according to the size of the port mobile machinery equipment, and then the port mobile machinery equipment is pushed from the loading port 3 onto the L-shaped bearing bars 7. The two symmetrical bearing bars 7 can support the equipment. Then, the lifting mechanism 4 is controlled by the controller again to raise the adjusting mechanism 6 and the bearing bars 7 carrying the port mobile machinery equipment to a suitable maintenance height, so that maintenance personnel can carry out maintenance work. After maintenance, reverse the lifting mechanism 4 to lower the equipment to a suitable height, remove the equipment from the loading port 3, rotate the rotating disc at the top of the brake lever to raise the brake block 8, release the restriction on the casters 2, and move the device to a suitable storage location using the casters 2. In addition, counterweights can be added to the counterweight box 9 to adjust the center of gravity of the device and enhance stability. Its outer storage drawer can store maintenance tools and spare parts for easy access.
