Description
Technical Field
[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a small lifting device for civil engineering construction. Background Technology
[0002] Civil engineering construction, also known as civil engineering construction, encompasses the construction of buildings, structures, and engineering works within various categories, including above-ground, underground, land, water, and underwater projects, such as houses, roads, railways, airports, bridges, water conservancy, ports, tunnels, water supply and drainage, and protection. During the construction process, it is sometimes necessary to use lifting equipment to raise or lower materials or workers to a certain height.
[0003] Existing technologies, such as Chinese Patent Publication No. CN213314038U, disclose a small lifting device for civil construction, including a lifting platform. A support rod is fixedly connected to the upper edge of the lifting platform, and a metal pipe is rotatably connected to the top of the support rod. Both ends of the metal pipe are closed structures. A rotating spray head is installed on the lower surface of the metal pipe. A water storage tank is installed on one side of the bottom of the lifting platform, and a water pump is installed on the top of the water storage tank. A corrugated hose is installed at the output end of the water pump, and a water suction pipe is connected to the input end of the water pump. The water suction pipe is located inside the water storage tank. A frame is provided around the outer wall of the lifting platform. This utility model delivers tap water to the metal pipe through the corrugated hose, and under the action of pressure, the rotating spray head sprays the tap water inside the metal pipe in the form of a mist. The fine water mist mixes with the dust generated by sand and gravel and falls downward under the action of gravity, which can effectively deal with the dust generated during the transportation of sand and gravel and provide a good working environment for workers. However, this utility model makes it inconvenient to transport materials to the lifting platform during use, and lacks protective measures for the materials, which may lead to the materials falling.
[0004] To address the problem that small lifting equipment used in civil construction is inconvenient for quickly and labor-saving material loading and protection, existing equipment sometimes lacks protective measures when lifting materials, which may cause materials to move or even fall during lifting. Other equipment, although equipped with protective measures, may obstruct the material loading process, making loading time-consuming and laborious. Therefore, improvements are needed.

[0007] Furthermore, the fixed shafts are arranged in two sets symmetrically, the locking blocks are multiple and evenly distributed around the circumference, the locking slots are multiple and evenly distributed around the circumference, and a handrail is fixedly connected to the surface of the adjusting plate.
[0008] Furthermore, the expansion component includes a receiving groove, which is formed on the surface of the adjustment plate. An expansion plate is slidably connected to the surface of the receiving groove, and a fixing component is provided on the surface of the expansion plate.

[0014] 1. In this utility model, by setting an auxiliary mechanism, the movable ring is held and slid along the limiting rod and the first spring is pressed, so that the slot is disengaged from the block. After the restriction is removed, the adjusting plate can be freely rotated along the fixed axis to the appropriate position.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a small lifting device for civil construction, including a vehicle body 1, a lifting machine 2, a work platform 3 and an auxiliary mechanism 4. The lifting machine 2 is fixedly installed on the surface of the vehicle body 1, the work platform 3 is fixedly connected to the drive end of the lifting machine 2, and the auxiliary mechanism 4 is set on the surface of the work platform 3.
[0024] The specific setup and function of its auxiliary mechanism 4 will be explained below.
[0025] In this embodiment: the auxiliary mechanism 4 includes an adjustment component 41 and an extension component 42. The adjustment component 41 includes a fixed shaft 411, which is fixedly connected to the surface of the worktable 3. An adjustment plate 412 is rotatably connected to the surface of the fixed shaft 411. A locking block 413 is fixedly connected to the surface of the adjustment plate 412. A movable ring 414 is slidably connected to the surface of the fixed shaft 411. A slot 415 is opened on the surface of the movable ring 414. The locking block 413 is locked to the surface of the slot 415. A limit rod 416 is fixedly connected to the surface of the worktable 3. The movable ring 414 is slidably connected to the surface of the limit rod 416. A spring 417 is sleeved on the surface of the limit rod 416. One end of the spring 417 is fixedly connected to the surface of the worktable 3, and the other end of the spring 417 is fixedly connected to the surface of the movable ring 414.
[0026] The effect achieved by the above components is as follows: the movable ring 414 is held and slid along the limiting rod 416 and the spring 417 is pressed, so that the slot 415 is disengaged from the block 413. After the restriction is removed, the adjusting plate 412 can be freely rotated along the fixed shaft 411 to the appropriate position. Then the movable ring 414 is released, and the movable ring 414 is reset under the rebound action of the spring 417. The slot 415 continues to be locked with the block 413, restricting the rotation of the adjusting plate 412.
[0027] Specifically, there are two sets of fixed shafts 411 arranged symmetrically, multiple locking blocks 413 evenly distributed around the circumference, multiple locking slots 415 evenly distributed around the circumference, and a handrail 418 is fixedly connected to the surface of the adjusting plate 412.
[0028] The effects achieved by the above components are as follows: setting multiple locking blocks 413 and locking slots 415 is to facilitate the fixing of the adjustment plate 412 at multiple angles; setting handrails 418 can not only provide assistance when materials and workers use the adjustment plate 412 to enter the workbench 3, but also work with the adjustment plate 412 and extension plate 422 to fix the materials and prevent them from moving randomly and falling or hitting the workers.
[0029] Specifically, the expansion component 42 includes a receiving groove 421, which is formed on the surface of the adjustment plate 412. An expansion plate 422 is slidably connected to the surface of the receiving groove 421, and a fixing component 43 is provided on the surface of the expansion plate 422.
[0030] The above components achieve the following effects: the receiving slot 421 is set to store the expansion plate 422, the expansion plate 422 is set to be stored away when not in use to reduce space occupation, and when in use, it plays a role in expanding the space and assisting in fixing the adjustment plate 412.
[0031] Specifically, an anti-detachment plate 423 is fixedly connected to the surface of the expansion plate 422, and an anti-detachment groove 424 is provided on the surface of the receiving groove 421. The surfaces of the anti-detachment plate 423 and the anti-detachment groove 424 are slidably connected.
[0032] The effect achieved by the above components is that the anti-detachment plate 423 and the anti-detachment groove 424 are set to prevent the extension plate 422 from completely detaching from the adjustment plate 412 without affecting the sliding storage and unfolding of the extension plate 422.
[0033] Specifically, the fixing component 43 includes a fixing groove 431, which is formed on the surface of the expansion plate 422. The surface of the expansion plate 422 is provided with an insertion hole 432 and a sliding groove 433. A plug rod 434 is slidably connected to the surface of the sliding groove 433.
[0034] The effects achieved by the above components are as follows: the fixing groove 431 is provided to facilitate the interlocking and fixing of the two sets of expansion plates 422; the insertion hole 432 and the insertion rod 434 are provided to facilitate the fixing of the two sets of expansion plates 422; and the sliding groove 433 is provided to facilitate the insertion rod 434 to disengage from the insertion hole 432 and release the fixing of the two sets of expansion plates 422.
[0035] Specifically, the insertion rod 434 is adapted to the insertion hole 432, and a pull plate 435 is fixedly connected to the surface of the insertion rod 434. The pull plate 435 is slidably connected to the surface of the slide groove 433.
[0036] The effect achieved by the above components is that the pull plate 435 is provided to facilitate the pulling of the insertion rod 434.
[0037] Specifically, a second spring 436 is fixedly connected to the surface of the pull plate 435, and the end of the second spring 436 away from the pull plate 435 is fixedly connected to the surface of the slide groove 433.
[0038] The effect achieved by the above components is that the spring 436 is set so that the insertion rod 434 can be locked into the insertion hole 432, and its rebound effect can facilitate the reset of the insertion rod 434.
[0039] Working principle: By setting up auxiliary mechanism 4, the movable ring 414 is held and slid along the limiting rod 416, pressing the spring 417, so that the slot 415 disengages from the locking block 413. After the restriction is lifted, the adjusting plate 412 can rotate freely along the fixed shaft 411 to the appropriate position. Then, the movable ring 414 is released, and under the rebound action of the spring 417, the movable ring 414 returns to its original position. The slot 415 continues to be locked with the locking block 413, restricting the rotation of the adjusting plate 412. When it is necessary to load materials or personnel, the adjusting plate 412 is rotated to an inclined state, and the expansion plate 422 partially slides out from the receiving groove 421, allowing materials or personnel to be loaded. Using the inclined plane and handrail 418, it is easier to enter the workbench 3. When it is necessary to protect materials and personnel, bring the two sets of adjusting plates 412 close together and rotate them to an appropriate angle. Then, pull out the two sets of extension plates 422. First, hold the pull plate 435 and pull the insertion rod 434 along the slide groove 433 and press the second spring 436. After the two sets of adjusting plates 412 are closed, release the pull plate 435. Under the rebound action of the second spring 436, the insertion rod 434 is inserted into the insertion hole 432. The two sets of adjusting plates 412 and extension plates 422 are fixed. With the handrail 418, the materials are fixed to prevent them from moving randomly and falling or hitting the personnel.
[0040] By setting up an auxiliary mechanism 4, using an adjustable plate 412 that can be rotated and fixed at an appropriate angle, and in conjunction with an extension plate 422 that can be retracted and unfolded, materials or workers can be quickly and effortlessly put into the workbench 3. The materials can also be protected to prevent them from moving around and falling or hitting workers, thus effectively improving the convenience of the equipment.
