Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a hoisting machine for building engineering. Background Technology

[0002] Construction engineering refers to civil building engineering, industrial building engineering, structural engineering, and supporting facilities such as roads, communications, and pipelines of various structural forms. During the construction process of construction engineering, hoisting mechanisms are often used to transport and move building materials.

[0003] Patent document CN221116703U discloses a building material hoisting mechanism for construction projects, comprising: a lifting ring with a connecting plate connected to its lower end; bolts penetrating the left and right ends of the connecting plate and the upper end of the mounting block; and a first connecting rod penetrating the lower end of the mounting block. This building material hoisting mechanism has a good positioning structure, preventing building materials from falling to the ground during transportation, thereby improving work efficiency and reducing labor costs.

[0004] In actual use, the building material hoisting mechanism proposed in the above patent documents only uses clamping plates and load-bearing plates to clamp and limit the building materials. However, the contact range between the clamping plate and the surface of the building materials is limited, and there is also a lack of protective structure at the bottom of the building materials, which makes it impossible to guarantee the stability of the building materials during hoisting. Therefore, it is necessary to improve the problems existing in the hoisting mechanism. Utility Model Content

[0005] This utility model discloses a hoisting machine for construction engineering. To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] A hoisting machine for construction engineering includes a hoisting frame. A bidirectional adjusting screw is provided on the upper surface of the hoisting frame. A movable block is threadedly connected to the surface of the bidirectional adjusting screw. The bottom of the movable block extends to the bottom of the hoisting frame, and two limiting frames are fixedly connected to the lower surface of the movable block. A limiting mechanism is provided between the two limiting frames.

[0007] The limiting mechanism includes a limiting support box fixedly connected to the bottom of the limiting frame. A circular through hole is opened on the upper surface of the limiting support box. A linkage column is slidably arranged on the inner wall of the circular through hole. A support base block is fixedly connected to the top of the linkage column. A linkage pull rod is rotatably connected to both sides of the support base block. A movable crank is rotatably connected to the side of the limiting frame. A limiting abutment block is fixedly connected to the top of the movable crank.

[0008] By setting a limiting frame and limiting mechanism below the hoisting frame, the bottom of the building material can be limited and supported by the limiting support box, and the weight of the steel itself can be used to press down on the support block, thereby using two limiting clamping blocks to clamp and limit the building material surface.

[0009] In a preferred embodiment, the end of the linkage rod away from the support base is rotatably connected to the surface of the movable crank.

[0010] In a preferred embodiment, the surface of the limiting and clamping block is provided with an arc-shaped groove, and the inner wall of the arc-shaped groove is fixedly connected with a number of rubber protrusions.

[0011] By providing an arc-shaped groove and a rubber protrusion on the surface of the limiting and clamping block, the rubber protrusion can be used for cushioning and anti-slip.

[0012] In a preferred embodiment, the side of the limiting frame is provided with a strip-shaped through hole, the position of which corresponds to the movable crank, and the movable crank is slidably connected to the inner wall of the strip-shaped through hole.

[0013] In a preferred embodiment, a linkage plate is fixedly connected to the bottom end of the linkage column, a fixed connecting column is fixedly connected to the lower surface of the linkage plate, the bottom end of the fixed connecting column extends to the outside of the limiting support box, and a reset top block is fixedly connected thereto.

[0014] In a preferred embodiment, two reset support springs are fixedly connected to the inner bottom wall of the limiting support box, and the top end of the reset support spring is fixedly connected to the lower surface of the linkage plate.

[0015] By setting a reset support spring and a reset top block, the limit blocks on both sides can automatically expand and reset when the limit mechanism lands, thus achieving the effect of automatically releasing the limit and facilitating the quick loading and unloading of building materials by workers.

[0016] In a preferred embodiment, two sliders are fixedly connected to the lower surface of the limiting frame, and a protective base is provided at the bottom of the limiting frame. Both sides of the protective base are provided with strip-shaped mounting grooves, and a limiting slide rod is fixedly connected to the inner wall of the strip-shaped mounting groove. The sliders are slidably connected to the surfaces of the limiting slide rods.

[0017] By setting up a protective base frame, the bottom of the building materials can be protected to a certain extent, preventing the materials from suddenly falling.

[0018] In a preferred embodiment, the upper surface of the hoisting frame is provided with an adjustment through hole, the position of which corresponds to the movable block, and the movable block is slidably connected to the inner wall of the adjustment through hole.

[0019] In a preferred embodiment, two sling fixing plates are fixedly connected to the upper surface of the hoisting frame, the bidirectional adjusting screw is rotatably connected between the two sling fixing plates, and an adjusting motor is fixedly installed on the side of the sling fixing plate.

[0020] As can be seen from the above, the hoisting machine for construction engineering provided by this utility model has the following technical effects.

[0021] Firstly, by setting a limiting frame and limiting mechanism below the hoisting frame, the bottom of the building material can be limited and supported by the limiting support box. The weight of the steel itself presses down on the support block, thereby driving the linkage rods and movable cranks on both sides to rotate inward. Then, the two limiting blocks are used to clamp and limit the surface of the building material, thereby improving the stability of the building material during hoisting. When the limiting mechanism lands, the limiting blocks on both sides can automatically expand and reset, achieving the effect of automatically releasing the limit, which facilitates the quick loading and unloading of building materials by the staff.

[0022] Secondly, by setting a two-way adjusting screw at the top of the hoisting frame, the distance between the two movable blocks can be adjusted and positioned by adjusting the motor, thereby adjusting the position of the two bottom limiting mechanisms. This is suitable for hoisting and fixing building materials of different lengths, improving the practicality of the hoisting mechanism. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1 and Figure 2 A hoisting machine for construction engineering includes a hoisting frame 1. A bidirectional adjusting screw 2 is provided on the upper surface of the hoisting frame 1. A movable block 3 is threadedly connected to the surface of the bidirectional adjusting screw 2. The bottom of the movable block 3 extends to the bottom of the hoisting frame 1, and two limiting frames 4 are fixedly connected to the lower surface of the movable block 3. A limiting mechanism 5 is provided between the two limiting frames 4.

[0031] It should be noted that two sling fixing plates 11 are fixedly connected to the upper surface of the hoisting fixing frame 1, and the bidirectional adjusting screw 2 is rotatably connected between the two sling fixing plates 11. An adjusting motor 12 is fixedly installed on the side of the sling fixing plate 11.

[0032] The upper surface of the hoisting frame 1 is provided with an adjustment through hole 10, the position of which corresponds to the movable block 3, and the movable block 3 is slidably connected to the inner wall of the adjustment through hole 10.

[0033] It is worth noting that by setting a bidirectional adjusting screw 2 at the top of the hoisting and fixing frame 1, the distance between the two movable blocks 3 can be adjusted and positioned by adjusting the motor 12, thereby adjusting the position of the two bottom limiting mechanisms 5. This is suitable for hoisting and fixing building materials of different lengths, improving the practicality of the hoisting mechanism.

[0034] It should be noted that two sliders 7 are fixedly connected to the lower surface of the limiting frame 4, and a protective base frame 8 is provided at the bottom of the limiting frame 4. Both sides of the protective base frame 8 are provided with strip-shaped mounting grooves, and the inner wall of the strip-shaped mounting groove is fixedly connected to a limiting slide rod 9. The sliders 7 and the surfaces of the limiting slide rod 9 are slidably connected.

[0035] Reference Figure 3 and Figure 4In a preferred embodiment, the limiting mechanism 5 includes a limiting support box 501 fixedly connected to the bottom of the limiting frame 4. A circular through hole is provided on the upper surface of the limiting support box 501. A linkage column 502 is slidably arranged on the inner wall of the circular through hole. A support base block 503 is fixedly connected to the top of the linkage column 502. A linkage pull rod 504 is rotatably connected to both sides of the support base block 503. A movable crank rod 505 is rotatably connected to the side of the limiting frame 4.

[0036] It should be noted that a strip-shaped through hole 6 is provided on the side of the limiting frame 4. The position of the strip-shaped through hole 6 corresponds to the movable crank 505, and the movable crank 505 is slidably connected to the inner wall of the strip-shaped through hole 6.

[0037] It should be further explained that the top end of the movable crank 505 is fixedly connected to a limiting block 506, and the surface of the limiting block 506 is provided with an arc-shaped groove 507, and the inner wall of the arc-shaped groove 507 is fixedly connected with several rubber protrusions 512.

[0038] In a preferred embodiment, the end of the linkage rod 504 away from the support base 503 is rotatably connected to the surface of the movable crank 505.

[0039] It should be noted that the bottom end of the linkage column 502 is fixedly connected to the linkage plate 508, and the lower surface of the linkage plate 508 is fixedly connected to the fixed connecting column 509. The bottom end of the fixed connecting column 509 extends to the outside of the limit support box 501 and is fixedly connected to the reset top block 510.

[0040] It should be further explained that two reset support springs 511 are fixedly connected to the inner bottom wall of the limit support box 501, and the top of the reset support springs 511 is fixedly connected to the lower surface of the linkage plate 508.

[0041] It is worth noting that by setting a limiting frame 4 and a limiting mechanism 5 below the hoisting frame 1, the bottom of the building material can be limited and supported by the limiting support box 501. The weight of the steel itself presses down on the support block 503, thereby driving the linkage rod 504 and movable crank rod 505 on both sides to rotate inward. Then, the two limiting clamping blocks 506 are used to clamp and limit the surface of the building material, thereby improving the stability of the building material during hoisting. When the limiting mechanism 5 lands, the reset top block 510 contacts the ground and drives the fixed connecting column 509 to move upward, thereby driving the linkage column 502 to reset. This causes the limiting clamping blocks 506 on both sides to automatically open and reset, achieving the effect of automatically releasing the limit and facilitating the quick loading and unloading of building materials by the staff.

[0042] Working principle: In use, the adjusting motor 12 first drives the bidirectional adjusting screw 2 to rotate, which in turn drives the two movable blocks 3 to move in the adjusting through holes 10 on the surface of the hoisting and fixing frame 1. The distance between the two limiting frames 4 is adjusted according to the length of the building material. Then, the bottom of the building material is placed on the surface of the supporting base block 503. Under the action of the building material's gravity, the linkage plate 508 moves downward. The linkage plate 508 drives the two linkage rods 504 to rotate inward, which in turn drives the movable cranks 505 on both sides of the building material to rotate on the surface of the limiting frame 4. The limiting abutment blocks 506 at the ends of the movable cranks 505 abut and limit the two sides of the building material, achieving the effect of automatic limiting. When unloading the building material, the reset support spring 511 and the reset top block 510 can automatically reset and release the limiting blocks 506, reducing manual operation and improving work efficiency.

[0043] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
