Description

Technical Field

[0001] The utility model relates to the technical field of sliding frames, in particular to a sliding frame for high-altitude construction of prefabricated steel structure buildings. Background Technique

[0002] The structural system of a prefabricated steel structure building is a prefabricated building composed of steel components; compared with concrete buildings, prefabricated steel structure buildings do not have on-site cast-in-place joints, have a faster installation speed, and it is easier to ensure the construction quality; steel structures are ductile materials, have better seismic performance, and compared with concrete structures, steel structures have a lighter self-weight and lower foundation cost.

[0003] During the assembly process of existing steel structure buildings, a crane is usually used for hoisting. Especially during high-altitude assembly, it cannot be hoisted in place at one time and requires manual adjustment continuously.

[0004] Chinese Patent No. CN211974388U discloses a sliding frame for high-altitude construction of prefabricated steel structure buildings, specifically discloses that a lifting frame for installing a chain block is provided at the top of the vehicle frame, and inner guide rails are fixed at the lower parts on both sides inside the vehicle frame and the outer support feet; a sliding trolley for transporting steel components is movably fitted on the inner guide rails; by moving the sliding trolley, the sliding trolley is moved to the assembly point. However, this sliding frame has the following defects: 1. For large components, after the large component is lifted into the sliding trolley by a crane, there is a high probability that the angle between the large component and the assembly point is not corresponding. Therefore, the staff needs to frequently adjust the angle of the large component to ensure that the angle between the large component and the assembly point is corresponding.

[0005] Therefore, we designed a sliding frame for high-altitude construction of prefabricated steel structure buildings that can conveniently adjust the angle of large components. Content of the Utility Model

[0006] In order to overcome the deficiencies in the background technique, the utility model discloses a sliding frame for high-altitude construction of prefabricated steel structure buildings.

[0007] To achieve the above-mentioned invention purpose, the utility model adopts the following technical scheme:

[0008] A sliding frame for high-altitude construction of prefabricated steel structure buildings, including a vehicle frame, pulleys are provided at the bottom of the vehicle frame, a support column is provided at one section of the top of the vehicle frame, a horizontal guide rail is installed at the upper end of the support columns on the same side of the vehicle frame, and a sliding seat is slidably connected to the top of the horizontal guide rail body, and a supporting member for supporting a steel component is rotatably connected to the top of the sliding seat.

[0009] Preferably, a horizontal slide rail pair perpendicular to the horizontal guide rail is provided at the top of the sliding seat, and the supporting member is rotatably connected to the moving part of the horizontal slide rail pair.

[0010] Preferably, the bottom of the sliding seat is provided with a rotating column rotatably connected to the moving part of the horizontal slide rail pair, and a plain bearing is coaxially sleeved on the column body of the rotating column to reduce the friction between the sliding seat and the moving part of the horizontal slide rail pair.

[0011] Preferably, the sliding seat has a magnetic structure for adsorbing steel members.

[0012] Preferably, a construction platform is laid on the top surface of the vehicle frame.

[0013] Preferably, a blocking rod is provided between the outer ends of the two horizontal guide rails.

[0014] Preferably, a rack is provided on the side wall surface of the horizontal guide rail along its length direction, a driving motor is provided on the sliding seat, and a transmission gear meshing with the rack is fixedly sleeved on the output shaft of the driving motor.

[0015] Preferably, pulling members are provided on both sides of the vehicle frame to facilitate pulling or hoisting the vehicle frame.

[0016] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0017] 1. Since two sets of horizontal guide rails, sliding seats and supporting members are provided, one of the sets can be moved, causing one end of the steel member to shift, realizing the function of adjusting the angle of the steel member;

[0018] 2. Due to the rotational connection between the supporting member and the sliding seat, during the process of adjusting the angle of the steel member, the supporting member can rotate synchronously with the steel member, ensuring that there is no relative rotation between the supporting member and the steel member, which may damage the protective layer on the outer surface of the steel member;

[0019] 3. When adjusting the angle of the steel member, the steel member will move in a direction perpendicular to the moving direction of the sliding seat. The rotational connection of the supporting member can prevent the relative rotation between the steel member and the supporting member;

[0020] 4. When adjusting the angle of the steel member, due to the setting of the horizontal slide rail pair, relative sliding will occur between the supporting member and the moving part of the horizontal slide rail pair, which can prevent the relative sliding between the steel member and the supporting member.

Detailed implementation mode

[0024] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model. In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or positional relationship, it is only corresponding to the drawings of the present application for the convenience of describing the present utility model; it should be understood that if there are terms such as "end", "side", "end part", "side part", "transverse", "longitudinal", etc. indicating the orientation or positional relationship, it is only corresponding to the length and width of the corresponding component, that is, the "end part" indicates the head and tail areas in the length direction of the corresponding component, and the "side part" indicates the head and tail areas in the width direction of the corresponding component; it is for the convenience of describing the present utility model rather than indicating or implying that the device or element referred to must have a specific orientation.

[0025] Example 1, in combination with the attached Figure 1-2 , a sliding frame for high-altitude construction of an assembled steel structure building, includes a vehicle frame 1. A pulley 2 is provided at the bottom of the vehicle frame 1. As needed, for the convenience of the hoisting operation of the vehicle frame 1, pulling members 11 are provided on both side parts of the vehicle frame 1. At this time, the pulling members 11 can be structures such as lifting lugs and lifting rings, and can cooperate with the guide rails (not shown in the figure) installed on the steel structure building by hanging the pulleys 2 at the bottom of the vehicle frame 1. The pulling members 11 can also be correspondingly connected to an external traction machine (not shown in the figure). By pulling the pulling members 11 by the traction machine, the vehicle frame 1 can be moved, and then the steel members can be sent to the assembly point.

[0026] A support column 3 is provided at the top of a section of the vehicle frame 1. The upper ends of the support columns 3 on the same side of the vehicle frame 1 are provided with a horizontal guide rail 4. A sliding seat 5 is slidably connected to the top of the rail body of the horizontal guide rail 4, and a supporting member 6 for supporting the steel member is rotatably connected to the top of the sliding seat 5.

[0027] Furthermore, a rack 41 arranged along its length direction is provided on the side wall surface of the horizontal guide rail 4. The sliding seat 5 is provided with a driving motor 51, and a transmission gear 52 meshing with the rack 41 is fixedly sleeved on the shaft body of the output shaft of the driving motor 51; that is, it can be driven by the driving motor 51.

[0028] During hoisting, use a tower crane to hoist the steel component above the supporting member 6, and then lower the steel component. At this time, the position of the steel component is random. If the steel component hanging in the air is aligned manually, there will be a greater risk. At this time, the sliding seat 5 can move on the rail body of the horizontal guide rail 4, so that the sliding seat 5 moves below the steel component, and then place the steel component on the top surface of the sliding seat 5 through the tower crane; then pull the vehicle frame 1 by an external traction machine to move the steel component near the assembly point, and then move the sliding seat 5 on the rail body of the horizontal guide rail 4 to drive the corresponding end of the steel component to move, so as to realize the function of adjusting the angle of the steel component. After the angle of the steel component is adjusted, the two sliding seats 5 can be moved synchronously to move the steel component to the assembly point.

[0029] Due to the rotational connection between the supporting member 6 and the sliding seat 5, during the process of adjusting the angle of the steel component, the supporting member 6 can rotate synchronously with the steel component, ensuring that there is no relative rotation between the supporting member 6 and the steel component, so as to prevent the protective layer on the outer surface of the steel component from being damaged.

[0030] Furthermore, since the steel component will move in a direction perpendicular to the moving direction of the sliding seat 5 when adjusting the angle of the steel component, in order to prevent relative rotation between the steel component and the supporting member 6, a horizontal slide rail pair 7 perpendicular to the horizontal guide rail 4 is provided on the top of the sliding seat 5, and the supporting member 6 is rotationally connected to the moving part of the horizontal slide rail pair 7.

[0031] Even further, since the supporting member 6 and the moving part of the horizontal slide rail pair 7 will have relative sliding when adjusting the angle of the steel component, in order to reduce the wear between the supporting member 6 and the moving part of the horizontal slide rail pair 7, a rotating column 61 rotationally connected to the moving part of the horizontal slide rail pair 7 is provided at the bottom of the sliding seat 5, and a plain bearing 8 is coaxially sleeved on the column body of the rotating column 61 to facilitate reducing the friction between the sliding seat 5 and the moving part of the horizontal slide rail pair 7.

[0032] Embodiment 2, in combination with the attached Figure 1-2 , a sliding frame for high-altitude construction of an assembled steel structure building. On the basis of Embodiment 1, in order to prevent relative sliding between the steel component and the top surface of the supporting member 6, the sliding seat 5 has a magnetic attraction structure (not shown in the figure) for adsorbing the steel structure component; according to needs, the magnetic attraction structure can be a permanent magnet or an electromagnet. In this way, the steel component can be adsorbed by the magnetic attraction structure to ensure that there is no relative sliding between the steel component and the top surface of the supporting member 6.

[0033] Embodiment 3, in combination with the attached Figure 1-2, A sliding frame for high-altitude construction of prefabricated steel structure buildings. On the basis of Embodiment 1 or 2, to increase the construction area for workers, a construction platform 9 is laid on the top surface of the vehicle frame 1; as required, the height difference between the surface of the construction platform 9 and the top surface of the supporting member 6 is 1.2 to 1.5 meters, so that workers can assemble steel components in a comfortable posture. As required, an anti-slip layer is laid on the surface of the construction platform 9.

[0034] Embodiment 4, in combination with the attached Figure 1-2 , A sliding frame for high-altitude construction of prefabricated steel structure buildings. On the basis of any one of the embodiments of Embodiment 3, a retaining rod 10 is provided between the outer ends of the two horizontal guide rails 4; as required, a retaining end plate is provided at the inner end of the horizontal guide rail 4; this can prevent the sliding seat 5 from moving excessively and disengaging from the horizontal guide rail 4;

[0035] With this setting, the horizontal guide rail 4 and the retaining rod 10 form a horizontal U-shaped frame with an opening facing inwards. For workers, it also serves the function of installing guardrails, improving the installation factor during workers' construction.
