Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting device for a construction hoist. Background Technology

[0002] Construction hoists are commonly used construction machinery on construction sites, serving both personnel and materials. They are mainly used for the vertical transport of personnel and materials. They consist of a guide rail frame, a cage, and a drive assembly. The guide rail frame is equipped with a rack along the vertical direction, and the drive mechanism is connected to the cage and drives the cage to move up and down along the rack.

[0003] The guide rail frame consists of multiple interconnected standard sections. When assembling the standard sections, hoisting equipment installed on the cage is used to hoist the standard sections and assemble them to achieve the final shape of the guide rail frame.

[0004] However, after traditional hoisting equipment hoists the standard section to the front of the cage, it is usually necessary to manually hook the standard section to the top of the cage with a long pole and install the standard section. However, hooking the standard section with a long pole is not convenient and there are certain safety hazards in manual operation. Utility Model Content

[0028] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figures 1 to 4 As shown, a hoisting device for a construction hoist according to the present invention includes a base 9, a vertical arm 6, a boom 5, a hoisting assembly, and a telescopic grabbing mechanism. The bottom of the vertical arm 6 is fixedly connected to the base 9, the boom 5 is installed on the top of the vertical arm 6, the hoisting assembly is connected to the boom 5, and the telescopic grabbing mechanism is connected to the middle of the vertical arm 6.

[0030] The telescopic gripping mechanism includes a moving drive assembly, a moving slide 12, and a gripping assembly 1. A sliding hole is provided in the middle of the upright arm 6, and the moving slide 12 passes through the sliding hole. The moving drive assembly is installed on the upright arm 6, and the moving drive assembly is drivenly connected to the moving slide 12. The gripping assembly 1 is provided at one end of the moving slide 12.

[0031] The working principle of this utility model is as follows: When it is necessary to hoist a standard section during the actual use of the construction hoist, the base 9 can be installed on the top of the cage with bolts. Then, the standard section is hoisted by the hoisting assembly. After hoisting to the front of the cage, the moving drive assembly can be operated to drive the moving slide 12 to extend. Then, the grabbing assembly 1 grabs the standard section. Then, the moving slide 12 is controlled to retract and the standard section is released.

[0032] Furthermore, the gripping assembly 1 includes a mounting platform 101, a first rotating drive component 104, a first drive wheel 103, a rack 105, a fixing plate 102, and a gripper 108. One side of the mounting platform 101 is fixedly connected to one end of the movable slide table 12. A sliding groove is provided on both sides of the other side of the mounting platform 101. One rack 105 is slidably connected to one side of one sliding groove via a slider. Another rack 105 is slidably connected to the other side of another sliding groove via another slider. The first drive wheel 103 is provided between the two racks 105. The first drive wheel 103 is rotatably connected to the other side of the mounting platform 101. All racks 105 mesh with the first drive wheel 103. The first rotating drive component 104 is drivenly connected to the first drive wheel 103. One rack 105 is connected to a gripper 108 via a fixing plate 102.

[0033] As can be seen from the above description, when it is necessary to clamp the standard section, the first rotation drive 104 can be operated to drive the first drive wheel 103 to rotate. At the same time, the first drive wheel 103 meshes with the rack 105 and drives the two racks 105 to move closer. Meanwhile, the racks 105 drive the grippers 108 to move through the fixed plate 102 and grip the standard section through the two grippers 108.

[0034] Furthermore, the two grippers 108 are arranged relative to each other.

[0035] As can be seen from the above description, it is beneficial for the gripper 108 to better grasp the standard section.

[0036] Furthermore, the gripper 108 is made of a flexible material, and a deformation groove 107 is provided inside the gripper 108.

[0037] As can be seen from the above description, it is beneficial for the gripper 108 to make better contact with the standard section when gripping it, and the deformation of the deformation groove 107 increases the contact area between the gripper 108 and the standard section.

[0038] Furthermore, each of the grippers 108 is provided with an anti-slip strip 106.

[0039] As can be seen from the above description, this helps to prevent the standard section from slipping off.

[0040] Furthermore, the moving drive assembly includes a second rotating drive member 14, a second drive wheel 13, and a toothed plate 11. The second rotating drive member 14 is mounted on the outer surface of the vertical arm 6 and is drivenly connected to the second drive wheel 13. The toothed plate 11 is fixedly connected to the side of the moving slide table 12 near the second drive wheel 13, and the second drive wheel 13 meshes with the toothed plate 11.

[0041] As can be seen from the above description, when it is necessary to move the standard section that has been gripped, the second rotation drive 14 can be operated to drive the second drive wheel 13 to rotate. At the same time, the second drive wheel 13 meshes with the toothed plate 11 and drives the moving slide table 12 to slide in the sliding hole.

[0042] Furthermore, it also includes a limiting block 7, which is fixedly connected to the other end of the movable slide 12. The limiting block 7 is used to limit the movement range of the movable slide 12 within the sliding hole.

[0043] As can be seen from the above description, it is beneficial to limit the movement range of the movable slide 12 within the sliding hole and prevent the movable slide 12 from dislodging from the sliding hole.

[0044] Furthermore, it also includes a reinforcing rib 10, which is fixedly connected to the connection between the upright arm 6 and the base 9.

[0045] As can be seen from the above description, it is beneficial to improve the compressive strength between the upright arm 6 and the base 9.

[0046] Furthermore, the hoisting assembly includes an electric hoist 8, a hoisting rope 3, and a hook 2. The electric hoist 8 is mounted on the boom 6. One end of the hoisting rope 3 is connected to the electric hoist 8, and the other end of the hoisting rope 3 is connected to the hook 2. A pulley 4 is rotatably connected to the boom 5, and the hoisting rope 3 is connected to the pulley 4.

[0047] As can be seen from the above description, when it is necessary to hoist the standard section, the hook 2 can be hung on the standard section, and then the electric hoist 8 can be operated so that the electric hoist 8 can lift the hook 2 and the standard section through the hoisting rope 3. At the same time, the hoisting rope 3 moves through the pulley 4 to reduce friction.

[0048] Furthermore, it also includes a controller, which is electrically connected to both the hoisting assembly and the telescopic gripping mechanism.

[0049] As can be seen from the above description, it makes it more convenient for users to control the overall device. Example 1
