Description

Technical Field

[0001] This utility model relates to the field of lightweight lifting devices, and in particular to a gantry-type mobile lightweight lifting device. Background Technology

[0002] In many fields such as modern industrial production and logistics transportation, it is often necessary to lift and move light goods. Gantry cranes have become commonly used equipment in light lifting operations due to their simple structure and convenient operation.

[0003] However, traditional fixed lifting equipment has significant limitations in its application scenarios and cannot meet the needs of frequent changes in different work locations. In contrast, gantry mobile light lifting devices, with their mobility, can flexibly move between different work areas, improving the flexibility and efficiency of lifting operations. They play an important role in scenarios such as the installation and maintenance of equipment in small factory workshops and the handling and sorting of goods in warehouses.

[0004] However, traditional gantry-type mobile light lifting devices have some shortcomings in actual use. During use, stability needs to be improved. When lifting, only the moving wheels of traditional gantry-type mobile light lifting devices are in contact with the ground. Although the moving wheels can be locked, the line contact between the moving wheels and the ground makes them prone to slipping under the influence of external forces, causing the device to deviate, affecting the normal use of the device, and posing safety hazards.

[0005] To address these issues, a gantry-type mobile lightweight lifting device is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a gantry-type movable lightweight lifting device, which aims to improve the problems of poor device stability, easy slippage and deviation of the moving wheels when in contact with the ground line, and potential safety hazards in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a gantry-type movable lightweight lifting device, comprising a support plate, a support frame fixedly connected to the upper surface of the support plate, a horizontal plate fixedly connected to the inner surface of the support frame, a hoisting device provided at the bottom end of the horizontal plate, a moving wheel provided on the lower surface of the support plate, a support locking mechanism provided at the bottom end of the support plate, the support locking mechanism comprising a stabilizing component and a limiting component, and protective components provided at both the front and rear ends of the support plate;

[0008] The stabilizing component includes a handwheel, a screw fixedly connected to the lower surface of the handwheel, the screw passing through and threadedly connected to the inner surface of the support plate, a stabilizing plate rotatably connected to the lower surface of the screw, and a guide rod fixedly connected to the upper surface of the stabilizing plate.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a sleeve, which is fixedly connected to the rear surface of the stabilizing plate. A moving rod is elastically connected to the rear surface of the stabilizing plate via a compression spring. A connecting block is fixedly connected to the rear surface of the moving rod. A slider is fixedly connected to the rear surface of the connecting block. A locking block is slidably connected through the rear surface of the stabilizing plate. A sliding groove is formed on the front surface of the locking block. An oblique groove is formed through the left surface of the locking block. A sliding rod is fixedly connected through the inner surface of the stabilizing plate.

[0011] As a further description of the above technical solution:

[0012] The protective component includes a fixing block, which is fixedly connected to the front surface of the support plate. A rubber pad is piston-connected to the inner wall of the fixing block. A through hole is opened through the front surface of the rubber pad. A connecting rod is fixedly connected to the front surface of the rubber pad. A baffle is elastically connected to the front surface of the fixing block through a connecting spring. Brush bristles are fixedly connected to the lower surface of the baffle.

[0013] As a further description of the above technical solution:

[0014] The guide rod passes through and is slidably connected to the inner surface of the support plate, and the stabilizing plate is located in the center of the lower surface of the support plate.

[0015] As a further description of the above technical solution:

[0016] The movable rod passes through and is slidably connected to the rear surface of the sleeve, and the slider is slidably connected to the inner wall of the groove.

[0017] As a further description of the above technical solution:

[0020] The connecting rod passes through and is slidably connected to the front surface of the fixed block, and the connecting rod is fixedly connected to the rear surface of the baffle.

[0021] As a further description of the above technical solution:

[0022] The front surface of the baffle is set to be arc-shaped.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the stability of the device can be improved by cooperating with the support and locking mechanism. When the device is stationary and needs to be hoisted, the handwheel is turned to move the stabilizing plate and the locking block down. The locking block locks the moving wheel, and the stabilizing plate contacts the ground, increasing the grounding area. This effectively prevents the device from sliding and shifting due to external forces during hoisting, ensuring operational safety, reducing safety hazards, and ensuring the stable progress of lifting operations.

[0025] 2. In this utility model, the protective components can be combined to improve the protective performance of the device. The baffle, brush bristles and rubber pads work together to effectively prevent the moving wheels from being jammed by impurities. When encountering obstacles, the baffle can buffer and disperse the obstacles, and the damping buffer generated by the rubber pad can reduce the wear of the baffle, extend the service life of the device, ensure the smooth movement of the equipment, and improve work efficiency.

[0032] 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.

[0033] Reference Figures 1-3This utility model provides an embodiment of a gantry-type movable lightweight lifting device, including a support plate 1. A support frame 2 is fixedly connected to the upper surface of the support plate 1, and a horizontal plate 3 is fixedly connected to the inner surface of the support frame 2. The support plate 1, support frame 2, and horizontal plate 3 are used to connect the overall device. The support plate 1, support frame 2, and horizontal plate 3 are all made of metal, which can provide stable support. A hoisting device 4 is provided at the bottom end of the horizontal plate 3. The support plate 1, support frame 2, horizontal plate 3, and hoisting device 4 constitute the body of the gantry-type lightweight lifting device, which can realize the lifting function. A moving wheel 8 is provided on the lower surface of the support plate 1. The moving wheel 8 facilitates the movement of the device and ensures the convenience of the device. A support locking mechanism is provided at the bottom end of the support plate 1. The support locking mechanism can improve the stability of the device when it is idle and can quickly lock the moving wheel 8. The support locking mechanism includes a stabilizing component and a limiting component. Protective components are provided at both the front and rear ends of the support plate 1. The protective components can prevent the moving wheel 8 from being jammed by impurities.

[0034] Reference Figure 1 , Figure 2 , Figure 4 The stabilizing component includes a handwheel 51. A handle is located on the upper surface of the handwheel 51 away from the center for easy gripping and rotation. A screw 52 is fixedly connected to the lower surface of the handwheel 51. The centers of the handwheel 51 and the screw 52 are on the same axis. The screw 52 passes through and is threadedly connected to the inner surface of the support plate 1. A stabilizing plate 53 is rotatably connected to the lower surface of the screw 52. When the screw 52 rotates, the stabilizing plate 53 moves longitudinally. A guide rod 54 is fixedly connected to the upper surface of the stabilizing plate 53. The limiting component includes a sleeve 64, which is fixedly connected to the rear surface of the stabilizing plate 53. Two sets of limiting components are provided, symmetrically arranged about the center line of the stabilizing plate 53. The rear surface of the stabilizing plate 53 is elastically connected to a moving rod 66 via a compression spring 65. A connecting block 67 is fixedly connected to the rear surface of the moving rod 66, and a slider 68 is fixedly connected to the rear surface of the connecting block 67. The moving rod 66, the connecting block 67, and the slider 68 move synchronously. A locking block 61 is slidably connected through the rear surface of the stabilizing plate 53. The rear surface of the locking block 61 is set as an arc surface, which fits with the moving wheel 8. When it is in close contact with the moving wheel 8, it can keep the moving wheel 8 stable. A sliding groove is opened on the front surface of the locking block 61, and a slanted groove 62 is opened through the left surface of the locking block 61. A sliding rod 63 is fixedly connected through the inner surface of the stabilizing plate 53, and the sliding rod 63 fits with the slanted groove 62.

[0035] Reference Figure 1 , Figure 2 , Figure 4The guide rod 54 passes through and is slidably connected to the inner surface of the support plate 1. The guide rod 54 can only move longitudinally along the inner surface of the support plate 1, thus maintaining the stability of the longitudinal movement of the stabilizing plate 53. The stabilizing plate 53 is located in the center of the lower surface of the support plate 1. The moving rod 66 passes through and is slidably connected to the rear surface of the sleeve 64. The moving rod 66 moves in the front and back direction. When the moving rod 66 in the rear position moves backward, it will gradually protrude from the sleeve 64 and stretch and compress the spring 65 to generate a reaction force. The slider 68 is slidably connected to the inner wall of the groove and moves longitudinally. The inclined groove 62 is opened in an inclined shape with the front lower and the back higher. The sliding rod 63 is slidably connected to the inner wall of the inclined groove 62. When the locking block 61 cannot move longitudinally, the sliding rod 63 will squeeze the inner wall of the inclined groove 62 when it moves downward, thereby pushing the locking block 61 to move backward.

[0036] Reference Figures 1-3 The protective component includes a fixing block 73. Two sets of the protective component are symmetrically distributed in the front-back direction around the center line of the support plate 1. The fixing block 73 is fixedly connected to the front surface of the support plate 1. A rubber pad 74 is piston-connected to the inner wall of the fixing block 73. A through hole 75 is opened through the front surface of the rubber pad 74. The small diameter of the through hole 75 restricts the air flow rate and achieves a damping and buffering effect. A cavity is opened inside the fixing block 73. The cavity is composed of two columnar components. The diameter of the columnar component at the rear position is larger than that at the front position. A connecting rod 76 is fixedly connected to the front surface of the rubber pad 74. A baffle 71 is elastically connected to the front surface of the fixing block 73 through a connecting spring 77. Brush bristles 72 are fixedly connected to the lower surface of the baffle 71. Multiple sets of brush bristles 72 are arranged in an array on the lower surface of the baffle 71.

[0037] Reference Figures 1-3 The connecting rod 76 passes through and is slidably connected to the front surface of the fixed block 73. The connecting rod 76 moves in the back and forth direction. The connecting rod 76 is fixedly connected to the rear surface of the baffle 71. The connecting rod 76 and the baffle 71 move synchronously. When the baffle 71 in the front position moves backward, it will squeeze the connecting spring 77 to generate a reaction force. The front surface of the baffle 71 is set to be arc-shaped. Stones and other obstructions will be dispersed along the arc surface and will not cause obstruction.

[0038] Working principle: When using this device, if it needs to be moved, simply push it. When encountering stones or other obstacles, smaller obstacles will be swept away by the bristles 72, while larger obstacles will collide with the baffle 71 and slide to both sides along the arc surface of the baffle 71 after the impact, thus releasing the obstruction. During the collision, the baffle 71 will also move the connecting rod 76 and the rubber pad 74. When the rubber pad 74 moves, it will compress the air in the cavity. The air will pass through the through hole 75. Since the diameter of the through hole 75 is small, it will limit the air flow rate and produce a damping buffering effect. Furthermore, when the baffle 71 moves, it will also compress the connecting spring 77 to generate a reaction force, further achieving the buffering effect, preventing wear on the baffle 71, and ensuring the durability of the device.

[0039] When the device needs to be hoisted, hold the device steady and turn the handwheel 51 to drive the screw 52 to rotate, which in turn drives the stabilizing plate 53, guide rod 54, and locking block 61 to move downwards. When moving downwards, the locking block 61 will first contact the ground, and then the stabilizing plate 53 and guide rod 54 will continue to move downwards. The stabilizing plate 53 will drive the sliding rod 63 to move downwards and press against the inner wall of the inclined groove 62, causing the locking block 61 to open and lock the moving wheel 8, limiting the moving wheel 8 and ensuring the stability of the device. At the same time that the locking block 61 locks the moving wheel 8, the stabilizing plate 53 will also contact the ground. Contact increases the grounding area of ​​the device, improving its stability. When the locking block 61 opens, it also moves the slider 68, connecting block 67, and moving rod 66. The moving rod 66 stretches the compression spring 65 to generate a reaction force. When it is necessary to release the stable state, the handwheel 51 is rotated in the opposite direction to drive the screw 52 to reverse, thereby moving the stabilizing plate 53 upward. The reaction force of the compression spring 65 will also pull the moving rod 66, connecting block 67, slider 68, and locking block 61 to move in the opposite direction, releasing the limit on the moving wheel 8. At this time, the device can move.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
