Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, and in particular to a portable hoisting tool for construction projects. Background Technology

[0002] In construction projects (such as indoor pipeline installation, hoisting of small prefabricated components, and equipment placement), it is often necessary to hoist or move components weighing 50-300kg (such as steel pipes, concrete blocks, and electrical boxes) over short distances. These operations are often carried out in narrow spaces (such as corridors and indoor rooms) and the components vary greatly in size (from 0.5m to 3m in length), which places special demands on the flexibility, adaptability, and portability of hoisting tools.

[0003] However, existing technologies have some problems: existing hoisting tools cannot adjust the hoisting spacing, and most hooks adopt a fixed spacing design, which cannot adjust the suspension point according to the length of the object to be hoisted. This can easily lead to the center of gravity shifting or tilting of the object during hoisting, and even cause the risk of falling. Therefore, it is necessary to provide a portable hoisting tool for construction projects to solve the above technical problems. Utility Model Content

[0004] This utility model provides a portable hoisting tool for construction projects, which solves the technical problems of existing hoisting tools, such as the inability to adjust the hoisting spacing, the fact that most hooks adopt a fixed spacing design, and the inability to adjust the suspension point according to the length of the object to be hoisted, which easily leads to the center of gravity shifting, tilting, or even the risk of falling when the object is hoisted.

[0005] To solve the above-mentioned technical problems, this utility model provides a portable hoisting tool for construction projects, comprising:

[0006] The hoisting shell has lifting lugs fixedly connected to both sides of its upper end, and fixed columns are provided on both sides of the interior of the hoisting shell. The lower end of the fixed column extends to the lower end of the hoisting shell and is fixedly connected to a rotating fixing component. The lower end of the rotating fixing component is fixedly connected to a hook, and the hook includes an anti-detachment buckle.

[0007] An adjustment assembly, located within the lifting housing, is used to adjust the suspension spacing of the hook.

[0008] Preferably, the adjustment component includes a servo motor, the output end of which is fixedly connected to a positive and negative lead screw, and both sides of the surface of the positive and negative lead screw are threaded with nut seats, the lower end of which is fixedly connected to the upper end of the fixed column.

[0009] Preferably, guide blocks are fixedly connected to both the front and rear sides of the nut seat, and guide rods are slidably connected inside the guide blocks, with the guide rods being laterally fixed inside the hoisting shell.

[0010] Preferably, one end of the positive and negative lead screw is fitted with a bearing seat, and one side of the bearing seat is fixedly connected to the right side inside the hoisting housing.

[0011] Preferably, a lifting chain is fixedly connected to the lifting lug, and a lifting ring is fixedly connected to the upper end of the lifting chain.

[0012] Compared with related technologies, the portable hoisting tool for construction projects provided by this utility model has the following beneficial effects:

[0013] This utility model provides a portable hoisting tool for construction projects. By adjusting the settings of the components, the hook spacing can be infinitely adjusted within the range of 30cm-150cm (with an accuracy of 1mm). It can be adapted to various components with lengths of 0.5m-3m (such as short steel pipes, long precast slabs, and wide equipment boxes). Compared with fixed-spacing tools, the adaptability range is improved, and the problem of component tilting caused by mismatched spacing is completely solved, thus improving the hoisting balance.

[0014] This utility model provides a portable hoisting tool for construction projects. By setting up a bearing seat, it plays a role in ensuring the smooth rotation of the positive and negative lead screws during use, preventing the positive and negative lead screws from shaking during use.

[0015] This utility model provides a portable hoisting tool for construction projects. Through the cooperation of the guide block and the guide rod, the nut seat is moved smoothly during use, preventing radial swaying and increasing the load-bearing capacity of the nut seat.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Example 1:

[0022] Please see Figure 1-3 This utility model provides a technical solution: a portable hoisting tool for construction engineering, comprising: a hoisting shell 1, with lifting lugs 2 fixedly connected to both sides of the upper end of the hoisting shell 1, and fixing columns 3 provided on both sides inside the hoisting shell 1, the lower end of the fixing column 3 extending to the lower end of the hoisting shell 1 and fixedly connected to a rotating fixing component 4, the lower end of the rotating fixing component 4 being fixedly connected to a hook 5, the hook 5 including an anti-detachment buckle and an adjustment component 6, the adjustment component 6 being located in the hoisting shell 1, and the adjustment component 6 being used to adjust the suspension spacing of the hook 5.

[0023] In this implementation plan, the lifting ring 11 is first connected to an external lifting device, such as a small crane or a manual hoist. Then, the optimal suspension point spacing of the component to be lifted is measured, and the servo motor 61 is started. The servo motor 61 drives the positive and negative lead screws 62 to rotate through the bearing seat 9. The rotation of the positive and negative lead screws 62 causes the nut seat 63 to move relative to each other.

[0024] Example 2:

[0025] Please see Figure 1-3 As shown, based on Embodiment 1, this utility model provides a technical solution:

[0026] In this embodiment: the nut seat 63 drives the guide block 7 to slide on the guide rod 8. At the same time, the nut seat 63 drives the fixed column 3 and the lower end hook 5 to adjust the spacing and adjust the hook 5 to a suitable spacing. After confirming that the spacing of the hook 5 matches the suspension point of the component, the servo motor 61 is turned off to complete the adjustment.

[0027] The working principle of the portable hoisting tool for construction engineering provided by this utility model is as follows: The adjustment component 6 includes a servo motor 61, the output end of the servo motor 61 is fixedly connected to a positive and negative lead screw 62, both sides of the surface of the positive and negative lead screw 62 are threaded with nut seats 63, the lower end of the nut seat 63 is fixedly connected to the upper end of the fixed column 3, the front and rear sides of the nut seat 63 are fixedly connected to guide blocks 7, the inside of the guide block 7 is slidably connected to a guide rod 8, the guide rod 8 is horizontally fixedly connected to the inside of the hoisting shell 1, one end of the positive and negative lead screw 62 is sleeved with a bearing seat 9, one side of the bearing seat 9 is fixedly connected to the right side inside the hoisting shell 1, a hoisting chain 10 is fixedly connected to the hoisting lug 2, and a hoisting ring 11 is fixedly connected to the upper end of the hoisting chain 10.

[0028] Implementation steps for the first innovation point:

[0029] Step 1: First, connect the lifting ring 11 to the external lifting equipment, such as a small crane, manual hoist, etc., and then measure the optimal suspension point spacing of the component to be lifted;

[0030] Step 2: Restart the servo motor 61. The servo motor 61 drives the positive and negative lead screws 62 to rotate through the bearing seat 9. The rotation of the positive and negative lead screws 62 causes the nut seat 63 to move relative to each other.

[0031] Implementation steps for the second innovation point:

[0032] Step 1: Nut seat 63 drives guide block 7 to slide on guide rod 8, and at the same time nut seat 63 drives fixed column 3 and lower end hook 5 to adjust the spacing;

[0033] Step 2: Adjust the hook 5 to a suitable spacing. After confirming that the spacing of the hook 5 matches the suspension point of the component, turn off the servo motor 61 to complete the adjustment.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
