Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering testing technology, specifically a lifting mechanism for engineering testing. Background Technology
[0002] In some engineering construction processes, it is often necessary to inspect high-altitude areas of buildings. For example, during the construction of some steel structure workshops, inspectors need to climb to high places to inspect the connections of the steel structure. At this time, a lifting mechanism is needed to raise the inspectors to a higher position for convenient inspection. However, the ground of some steel structure workshops is not a flat cement road, but sometimes soil. In this case, a simple lifting mechanism cannot guarantee the stability of the bottom, and it is easy to tilt and fall, which poses certain safety hazards. Therefore, a lifting mechanism for engineering inspection is proposed to address the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a lifting mechanism for engineering testing to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] As an optional solution of the lifting mechanism for engineering testing described in this utility model, the lifting mechanism for engineering testing includes a lifting trolley, moving wheels and a lifting frame;
[0006] The top of the lifting trolley is fixedly connected to a lifting frame, and the other end of the lifting frame is fixedly connected to a testing platform for the testing personnel to stand on.
[0007] The bottom of the lifting trolley is also fixedly connected with evenly distributed moving wheels;
[0008] The lifting trolley is fixedly connected to an expansion mechanism on both sides;
[0009] The expansion mechanism includes a fixed frame, a motor, and a threaded shaft. The outer side of the fixed frame is fixedly connected to the lifting trolley. The inside of the fixed frame is fixedly connected to a vertically arranged motor, and the end of the motor's main shaft is fixedly connected to a threaded shaft. The other end of the threaded shaft is rotatably connected to the fixed frame.
[0010] A movable sleeve is helically connected to the outer side of the threaded shaft, a sliding block is fixedly connected to the outer side of the movable sleeve, and a rotating component is fixedly connected to the other side of the sliding block. An outer expansion plate is fixedly connected to the other end of the rotating component.
[0011] As an optional solution of the lifting mechanism for engineering testing described in this utility model, the outer side of the expansion plate is fixedly connected with a handle that facilitates the rotation of the expansion plate.
[0012] In some construction projects, it is often necessary to inspect high-altitude areas of buildings. For example, during the construction of steel structure workshops, inspectors need to climb to high places to inspect the connections of the steel structure. In this case, a lifting mechanism is needed to raise the inspectors to the high place for convenient inspection. However, the ground of some steel structure workshops is not a flat cement road, but sometimes soil. In this case, a simple lifting mechanism cannot guarantee the stability of the bottom and is prone to tilting and falling, which poses certain safety hazards. When using this method, when moving to a soil area, first rotate the outer expansion plate to tilt it, then start the motor to drive the threaded shaft to rotate. The threaded shaft drives the moving sleeve to move down, and the moving sleeve drives the sliding block to move. At this time, the outer expansion plate can be lowered, and the insertion rod at the bottom of the outer expansion plate contacts the ground, thereby inserting into the ground, expanding the base area, and ensuring overall stability.
[0013] As an optional solution of the lifting mechanism for engineering testing described in this utility model, the bottom of the outer expansion plate is fixedly connected with uniformly distributed insert rods, and the insert rods are inclined and the bottom of the insert rods are pointed.
[0014] As an optional solution of the lifting mechanism for engineering testing described in this utility model, a blocking block is also fixedly connected inside the fixed frame.
[0015] As an optional solution of the lifting mechanism for engineering testing described in this utility model, the upper part of the sliding block is inclined, and the outer side of the sliding block is slidably connected to the fixed frame.
[0016] This device is equipped with two sets of outward expansion mechanisms, which can be controlled separately. When there is slight unevenness in the land on both sides, the outward expansion plate can be moved down to make stable contact with the ground, thereby achieving the purpose of stable reinforcement. When the outward expansion plate rotates, the sliding block is inclined above, which facilitates the rotation of the outward expansion plate.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] When this utility model is in use, when it is moved to a soil area, the outer expansion plate is first rotated to make it tilted, and then the motor is started to drive the threaded shaft to rotate. The threaded shaft drives the moving sleeve to move down, and the moving sleeve drives the sliding block to move. At this time, the outer expansion plate can be moved down, and the insertion rod at the bottom of the outer expansion plate contacts the ground, thereby inserting into the ground, expanding the chassis area, and ensuring overall stability.
[0019] Furthermore, this device is equipped with two sets of outward expansion mechanisms, which can be controlled separately. When there is slight unevenness on both sides of the land, the outward expansion plate can be moved down to make stable contact with the ground, thereby achieving the purpose of stable reinforcement. When the outward expansion plate rotates, the sliding block is inclined above, which facilitates the rotation of the outward expansion plate. Attached Figure Description

[0023] 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.
[0024] Example 1: Please refer to Figure 1 and Figure 2 This utility model provides a technical solution:
[0025] A lifting mechanism for engineering testing includes a lifting trolley 1, moving wheels 2, and a lifting frame 3;
[0026] The top of the aforementioned lifting trolley 1 is fixedly connected to a lifting frame 3, and the other end of the lifting frame 3 is fixedly connected to a testing platform 4 for the testing personnel to stand on.
[0027] The bottom of the aforementioned lifting trolley 1 is also fixedly connected with evenly distributed moving wheels 2;
[0028] The lifting trolley 1 mentioned above is fixedly connected to two sides by an expansion mechanism 5;
[0029] The aforementioned expansion mechanism 5 includes a fixed frame 501, a motor 502, and a threaded shaft 503. The outer side of the fixed frame 501 is fixedly connected to the lifting trolley 1. The motor 502 is fixedly connected to the inside of the fixed frame 501, and the threaded shaft 503 is fixedly connected to the end of the main shaft of the motor 502. The other end of the threaded shaft 503 is rotatably connected to the fixed frame 501.
[0030] The outer side of the aforementioned threaded shaft 503 is helically connected to a movable sleeve 504, the outer side of the aforementioned movable sleeve 504 is fixedly connected to a sliding block 505, and the other side of the sliding block 505 is fixedly connected to a rotating member 506, the other end of the aforementioned rotating member 506 is fixedly connected to an outer expansion plate 507.
[0031] The outer side of the aforementioned expansion plate 507 is fixedly connected with a handle 508 to facilitate the rotation of the expansion plate 507.
[0032] In some construction projects, it is often necessary to inspect high-altitude areas of buildings. For example, during the construction of steel structure workshops, inspectors need to climb to high places to inspect the connections of the steel structure. In this case, a lifting mechanism is needed to raise the inspectors to the high place for convenient inspection. However, the ground of some steel structure workshops is not a flat cement road, but sometimes soil. In this case, a simple lifting mechanism cannot guarantee the stability of the bottom and is prone to tilting and falling, which poses certain safety hazards. When using it, when moving to a soil area, first rotate the outer expansion plate 507 to tilt it. Then start the motor 502 to drive the threaded shaft 503 to rotate. The threaded shaft 503 drives the moving sleeve 504 to move down. The moving sleeve 504 drives the sliding block 505 to move. At this time, the outer expansion plate 507 can be lowered. At this time, the insertion rod 509 at the bottom of the outer expansion plate 507 contacts the ground and inserts into the ground, thereby expanding the base area and ensuring overall stability.
[0033] In this embodiment, the movable wheels 2 at the bottom of the lifting trolley 1 facilitate the movement of the lifting trolley 1, and the start of the lifting frame 3 facilitates the raising of the upper inspection platform 4, making it convenient for inspection personnel to carry out the inspection process. The protruding handle 508 facilitates the rotation of the expansion plate 507. Under the action of the rotating part 506, the expansion plate 507 can rotate with the sliding block 505, which facilitates the subsequent fixing purpose.
[0034] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 2 Specifically, the bottom of the aforementioned expansion plate 507 is fixedly connected with evenly distributed insertion rods 509, and the insertion rods 509 are inclined and the bottom of the insertion rods 509 are pointed.
[0035] A blocking block 510 is also fixedly connected inside the aforementioned fixed frame 501.
[0036] The upper part of the aforementioned sliding block 505 is inclined, and the outer side of the aforementioned sliding block 505 is slidably connected to the fixed frame 501.
[0037] This device is equipped with two sets of outward expansion mechanisms 5, which can be controlled separately. When there is slight unevenness on the ground on both sides, the outward expansion plate 507 can move down to make stable contact with the ground and achieve the purpose of stable reinforcement. When the outward expansion plate 507 rotates, the sliding block 505 is inclined above, which facilitates the rotation of the outward expansion plate 507.
[0038] In this embodiment, the blocking plate 510 is designed to block the insertion rod 509, which is inclined. When the expansion plate 507 rotates, the insertion rod 509 is in a vertical state, which facilitates the insertion rod 509 to be inserted into the ground to reinforce the lifting trolley 1. The bottom of the insertion rod 509 is pointed, which facilitates insertion into the ground for fixation. In normal use, when used on a flat cement road surface, it can remain stationary through the expansion mechanism 5 to ensure the normal use of the lifting trolley 1.
