Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for construction engineering, and in particular provides a fast resetting tool for adjustable base support arms of a disc-type scaffold. Background Art

[0002] As a new type of formwork support frame for bridges and subways in my country, the disc-type scaffolding is increasingly recognized by China's railway system and China's construction system. The bracket can be erected into different forms and functional formwork supports to meet the needs of various styles. The disc-type scaffolding is a complete system. The scaffolding boards and ladders can play a role in ensuring the stability of the shelf and the safety of the workers. Therefore, compared with other laying scaffolding, the hook-foot pedal disc fixed scaffolding increases the safety of the shelf. In addition, the stride and spacing of the scaffolding can be expanded, thereby expanding the construction space for workers and the supervision acceptance space.

[0003] At the construction site, when the adjustable base of the disc-type scaffolding is installed on site, the arm needs to be reset to the lowest end to facilitate the installation of the scaffolding, which is generally adjusted manually by workers. The arm reset of the on-site adjustable base requires special workers to manually adjust and reset it, and the construction is slow and takes a long time. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a disc-type scaffolding adjustable base arm quick reset tool, including a supporting rotating frame and a rotating driving member; the supporting rotating frame is provided with a U-shaped frame body with an opening downward, and a central rotating rod extending upward is provided in the middle of the top of the U-shaped frame body, and a guide sleeve is provided in the middle of the U-shaped frame body that is concentrically arranged with the central rotating rod and adapted to the outer diameter of the screw rod, and a lever extending outward and adapted to the adjustable base arm on the screw rod is symmetrically provided at the bottom of the U-shaped frame body; the rotating driving member is drivingly connected to the central rotating rod.

[0006] Furthermore, the shifting rod extends outward obliquely relative to the central rotating rod, and the angle between the extending direction of the shifting rod and the central rotating rod is 15°-75°.

[0007] Furthermore, a one-way ratchet pawl mechanism with adjustable transmission direction is provided between the central rotating rod and the U-shaped frame.

[0008] Furthermore, the central rotating rod includes an axially sliding and circumferentially fixed rod body and a sleeve, the sleeve is fixedly connected to the U-shaped frame, the rotating drive member is fixedly connected to the rod body, and a positioning screw is provided between the rod body and the sleeve.

[0009] Furthermore, the guide sleeve includes a left half sleeve and a right half sleeve that are symmetrically arranged and detachably connected. The left half sleeve is fixedly connected to the left inner side of the U-shaped frame, and the right half sleeve is fixedly connected to the right inner side of the U-shaped frame. The left half sleeve and the right half sleeve constitute a guiding structure that cooperates with the screw rod.

[0010] Furthermore, the selected rotating driving member is a motor member, and the motor shaft of the motor member is detachably drivingly connected to the central rotating rod.

[0011] Furthermore, the tool also includes a supporting member, and a supporting sleeve that rotates with the central rotating rod is provided at the front end of the supporting rod of the supporting member.

[0012] Furthermore, the armrest of the motor component is detachably connected to the rear end of the supporting rod of the supporting component via a connecting seat.

[0013] Furthermore, the rotary drive member is a wrench or a lever, and the central rotating rod is provided with a transmission joint adapted to the wrench or the lever.

[0014] Compared with the prior art manual rotation adjustment of the adjustable base arm of the disc-type scaffolding, the technical advantages of the utility model are at least reflected in:

[0015] By using the disc-type scaffolding adjustable base arm quick reset tool provided by the utility model, the guide sleeve of the U-shaped frame is installed outside the screw rod, and the lever is extended from the adjustable base arm gap on the screw rod, and then the central rotating rod is driven by the rotating driving member to drive the U-shaped frame to rotate, and the adjustable base and the arm are driven to rotate by the lever, thereby completing the lifting and lowering adjustment of the adjustable base and the arm. During the process, the guide sleeve sleeved outside the screw rod plays a rotation guiding role for the U-shaped frame, maintaining the rotation stability of the U-shaped frame. By using this tool, the height adjustment can be performed instead of the worker manually rotating the adjustable base of the scaffolding, thereby improving the efficiency of adjusting the height of the base arm and reducing the labor intensity of the adjustment process.

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present invention and its application or use. The present invention can be implemented in many different forms and is not limited to the embodiments herein. In the present invention, when a particular device is described as being between a first device and a second device, there may or may not be an intermediate device between the particular device and the first device or the second device. Example

[0029] like Figure 1 to Figure 2As shown, a disc-type scaffolding adjustable base arm quick reset tool includes a supporting rotating frame 1 and a rotating driving member 2; the supporting rotating frame 1 is provided with a U-shaped frame body 11 with an opening downward, and a central rotating rod 12 extending upward is provided in the middle of the top of the U-shaped frame body 11, and a guide sleeve 14 is provided in the middle of the U-shaped frame body 11, which is concentrically arranged with the central rotating rod 12 and adapted to the outer diameter of the screw rod 4, and a lever 15 extending outward and adapted to the arm of the adjustable base 5 on the screw rod 4 is symmetrically provided at the bottom of the U-shaped frame body 11; the rotating driving member 2 is drivingly connected to the central rotating rod 12.

[0030] The lever 15 extends obliquely outward relative to the central rotating rod 12, and the angle between the lever 15 and the central rotating rod 12 is 15°-75°. The rotary drive member 2 is a wrench or a lever, and the central rotating rod 12 is provided with a transmission joint adapted to the wrench or the lever.

[0031] like Figure 3 and Figure 4 As shown, the provided disc-type scaffolding adjustable base arm quick reset tool is used to install the guide sleeve 14 of the U-shaped frame 11 outside the screw rod 4, and the lever is extended from the gap between the adjustable base 5 arms on the screw rod 4, and then the central rotating rod 12 is driven by the rotating driving member 2 to drive the U-shaped frame 11 to rotate, and the adjustable base 5 and the arm are driven to rotate by the lever 15, thereby completing the lifting and lowering adjustment of the adjustable base 5 and the arm. During this period, the guide sleeve 14 mounted on the outside of the screw rod 4 plays a rotational guiding role for the U-shaped frame 11, thereby maintaining the rotational stability of the U-shaped frame 11.

[0032] In a specific embodiment, the central rotating rod is a 14mm diameter round steel, the top is provided with a hexagonal nut and the U-shaped frame is a 14mm diameter round steel bend, the angle between the lever and the central rotating rod is 45° and extends downward, and the guide sleeve is a steel pipe with a wall thickness of 3mm and an inner diameter of 50mm.

[0033] Furthermore, a one-way ratchet pawl mechanism 16 with adjustable transmission direction is provided between the central rotating rod 12 and the U-shaped frame 11, so that the manual wrench will not drive the central rotating rod to rotate when returning, thereby realizing the conversion of the manual reciprocating drive of the wrench into the continuous rotation of the central rotating rod. This tool can replace the manual rotation of the adjustable base of the scaffold by workers to adjust the height, improve work efficiency and reduce labor intensity. Example

[0034] like Figure 1 and Figure 2As shown, in this embodiment, the structure is upgraded and optimized, and a manual wrench is no longer used as a rotation drive component. The selected rotation drive component 2 is a motor component 21, and the motor shaft 22 of the motor component 21 is detachably connected to the central rotating rod 12. In addition, the tool also includes a supporting component 3, and the front end of the supporting rod 32 of the supporting component 3 is provided with a supporting sleeve 31 that rotates with the central rotating rod 12. The handrail 23 of the motor component 21 is detachably connected to the rear end of the supporting rod 32 of the supporting component 3 through a connecting seat 33.

[0035] The motor part can replace the manual wrench to realize high-speed rotation drive of the U-shaped frame, improve the rapid adjustment of the height of the adjustable base, and no longer need a rotating wrench. A supporting rod connected to the motor part is provided to realize simultaneous support of the U-shaped frame and the motor part, which is convenient for on-site operation. Example

[0036] On the basis of Example 1 and Example 2, the structure is optimized. Specifically, the central rotating rod 12 includes an axially sliding and circumferentially fixed rod body and a sleeve, the sleeve is fixedly connected to the U-shaped frame 11, the rotating drive member 2 is fixedly connected to the rod body, and a positioning screw is provided between the rod body and the sleeve.

[0037] Through this embodiment, the center rotating rod is adjustable in length. During use, the center rotating rod can be adjusted according to the installation status of the tool on the screw rod, the adjustment height change of the adjustable base, etc., thereby improving the flexibility of the tool during use, achieving convenience of operation, and expanding the use of the tool in different spatial environments. Example

[0038] On the basis of the above embodiments, the structure is optimized: the guide sleeve includes a left half sleeve and a right half sleeve that are symmetrically arranged and detachably connected, the left half sleeve is fixedly connected to the left inner part of the U-shaped frame 11, and the right half sleeve is fixedly connected to the right inner part of the U-shaped frame 11, and the left half sleeve and the right half sleeve constitute a guiding structure that cooperates with the screw rod 4.

[0039] Based on the above embodiments, the lever of the provided scaffolding adjustable base quick reset device can effectively clamp the base arm, and the guide sleeve is inserted into the screw rod to ensure that the base does not slide left and right when the arm is reset. The entire device is driven by the torque of the electric wrench to quickly reset the base arm. This device greatly improves the time-consuming and labor-intensive manual rotation adjustment of workers. The device improves the work efficiency of workers and saves labor.
