Description

Technical Field

[0001] The utility model belongs to the technical field of engineering construction, and particularly relates to a prefabricated component hoisting anti-deviation component. Background Art

[0002] Prefabricated components refer to steel, wood or concrete components that are prefabricated in a factory or on-site according to design specifications. Prefabricated components need to be hoisted when they are used. The hoisting is generally divided into three steps: lifting, lowering and installing. When in use, the prefabricated components need to be lifted and transported to the installation location, and then the prefabricated components are lowered to the installation location, and then the installation of the prefabricated components is completed through connectors. In the process of lifting and lowering, in order to avoid deviation of the lowered prefabricated components, it is necessary to reasonably use some auxiliary tools, such as positioning frames, oblique supports, etc. Auxiliary tools such as positioning frames and oblique supports can be pre-installed at the position where the components are lowered and installed, and then these tools can be used to assist and position the lowering and installation of the prefabricated components, so as to help control the position and stability of the prefabricated components, thereby preventing excessive deviation of the prefabricated components that are lifted and lowered.

[0003] For example, the Chinese invention patent with application number: CN202211087650.5 discloses an efficient installation device for prefabricated parts for infrastructure, including a hoist for hoisting prefabricated parts, and also including a positioning frame, on which the first positioning component, the second positioning component, the third positioning component and the fourth positioning component are respectively arranged on the left, right, front and back of the positioning frame, and the first positioning component, the second positioning component, the third positioning component and the fourth positioning component all include a retractable supporting leg unit, a driving unit arranged at the upper end of the supporting leg unit and a limiting unit arranged at the lower end of the supporting leg unit; the four driving units are used to transport the hydraulic oil to the four limiting units through their own oil pipes under the downward pressure of the prefabricated parts, and the four limiting units are used to respectively abut against the four sides of the base to correct the position of the prefabricated parts, thereby overcoming the problem that the prefabricated parts need manual support during the downward process, which is inefficient and has certain risks.

[0004] However, during the use of the installation device, the positioning frame needs to be connected to the prefabricated part through a conical pin before the position of the prefabricated part can be corrected through the limit unit. For wooden prefabricated parts, due to their relatively light texture, they are more easily affected by gravity, wind, etc. when they are lowered for installation, resulting in some rotation and swinging. In this case, the lowered prefabricated parts are prone to collision with the positioning frame, and the collision is likely to damage the wooden prefabricated parts. Utility Model Content

[0005] The utility model provides a prefabricated component hoisting anti-deviation assembly, aiming to solve the problem that the lowered prefabricated component is easy to collide with the positioning frame, causing damage to the prefabricated component.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A prefabricated component hoisting anti-deviation assembly comprises: a positioning frame, a plurality of inner side walls of the positioning frame are each provided with a contact soft plate, a plurality of buffer sleeves are provided between each contact soft plate and the inner side wall of the positioning frame, the upper portion of the contact soft plate is arranged in an arc shape, and the arc shape is arranged toward the outside of the positioning frame;

[0008] The interior of the buffer sleeve is hollow, a sliding hole is provided on the side of the buffer sleeve close to the contact soft plate, a connecting rod is slidably provided in the sliding hole, one end of the connecting rod is connected to the contact soft plate, the other end of the connecting rod extends into the interior of the buffer sleeve and is connected to a resistance plate, an auxiliary spring is provided between the side of the resistance plate away from the connecting rod and the buffer sleeve, the inner cavity of the buffer sleeve is filled with damping oil, a plurality of flow holes are provided on the resistance plate, and the connecting rod and the sliding hole are sealed.

[0009] Furthermore, a plurality of evenly distributed slots are provided on the circumferential side wall of the abutment plate, balls are clamped inside the slots, the balls roll with the slots, and the balls abut against the inner cavity side wall of the buffer sleeve.

[0010] Furthermore, a soft rubber ring is provided on the side wall where the abutment plate is connected to the connecting rod.

[0012] Furthermore, the positioning frame is in a rectangular configuration, and is formed by splicing two right-angle frames, and the two right-angle frames are connected by screws.

[0013] Compared with the prior art, the utility model has the following technical effects:

[0014] 1. The prefabricated component hoisting anti-deviation assembly described in the utility model can make contact with the wooden prefabricated component by using a soft contact plate. First, the soft contact plate can protect the wooden prefabricated component from excessive impact. Then, the damping effect of the damping oil in the buffer sleeve can absorb part of the impact to avoid deformation or damage of the wooden prefabricated component during the lowering process, thereby avoiding deviation in the positioning of the prefabricated component.

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the application and with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown, a prefabricated component hoisting anti-deviation assembly includes: a positioning frame 1, which can be preinstalled at the installation position during hoisting to control the position stability of the wooden prefabricated component and control the deviation. Contact soft plates 8 are arranged on several inner side walls of the positioning frame 1, and the contact soft plates 8 can be used as the first contact surface to contact the wooden prefabricated component. Several buffer sleeves 2 are arranged between each contact soft plate 8 and the inner side wall of the positioning frame 1. The upper part of the contact soft plate 8 is arranged in an arc shape, and the arc is arranged toward the outside of the positioning frame 1; the top of the arc setting can be used to guide the wooden prefabricated component, and the existence of the ladder can also be avoided to hit the wooden prefabricated component.

[0021] The interior of the buffer sleeve 2 is hollow, and a sliding hole 3 is provided on the side of the buffer sleeve 2 close to the contact soft plate 8. A connecting rod 7 is slidably provided in the sliding hole 3. One end of the connecting rod 7 is connected to the contact soft plate 8, and the other end of the connecting rod 7 extends to the inside of the buffer sleeve 2 and is connected to a contact plate 5. An auxiliary spring 11 is provided between the side of the contact plate 5 away from the connecting rod 7 and the buffer sleeve 2. The inner cavity of the buffer sleeve 2 is filled with damping oil 4, which is the main tool for shock absorption and buffering. A plurality of flow holes 6 are provided on the contact plate 5. The contact plate 5 serves as an antagonistic component, which can oppose the damping oil 4 after being compressed. The damping oil 4 can flow along the flow hole 6, and resistance can be generated in the process of flowing, so that the damping effect can be used to absorb the impact and quickly eliminate the vibration. The connecting rod 7 and the sliding hole 3 are sealed to prevent the damping oil 4 from flowing out.

[0022] like Figure 3 As shown, a plurality of evenly distributed grooves 9 are provided on the circumferential side wall of the abutment plate 5, and balls 10 are clamped inside the grooves 9. The balls 10 roll with the grooves 9, and the balls 10 abut against the inner cavity side wall of the buffer sleeve 2. The rolling of the balls 10 can eliminate the friction between the abutment plate 5 and the buffer sleeve 2, thereby preventing the friction from damaging the abutment plate 5 and the buffer sleeve 2.

[0023] like Figure 3As shown, a soft rubber ring 12 is provided on the side wall where the abutment plate 5 is connected to the connecting rod 7 , and the soft rubber ring 12 can be used to buffer the impact when the abutment plate 5 and the buffer sleeve 2 are in contact, so as to avoid damage to the abutment plate 5 and the buffer sleeve 2 due to the impact.

[0024] like Figure 3 As shown, both ends of the flow hole 6 are provided with expansion openings, and the diameters of the two ends of the flow hole 6 are larger than the diameter of the middle of the flow hole 6 .

[0025] like Figure 1 As shown, the positioning frame 1 is in a rectangular configuration, and the positioning frame 1 is formed by splicing two right-angle frames, and the two right-angle frames are connected by screws.

[0026] The working principle of the utility model is as follows: when in use, the wooden prefabricated part can first be contacted through the contact soft plate 8, thereby preventing the overly rigid positioning frame 1 from causing excessive impact on the wooden prefabricated part, and then the offset shaking of the wooden prefabricated part will cause an impact on the contact soft plate 8, and then the impact will squeeze the resistance plate 5 through the connecting rod 7, and then the damping oil 4 will flow along the flow hole 6, and the flowing damping oil 4 can produce a damping effect, and the damping effect can absorb and mitigate the impact effect, thereby avoiding the phenomenon that the wooden prefabricated part is deformed during the lowering process due to the impact, and avoiding the deformation causing excessive positioning deviation of the wooden prefabricated part.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
