Description

Technical Field

[0001] The utility model belongs to the technical field of scaffolds, and in particular relates to a multifunctional scaffold. Background Art

[0002] Scaffolding is a variety of supports set up at construction sites for workers to operate and solve vertical and horizontal transportation. Compared with large scaffolding at construction sites, small scaffolding is more suitable for home use or small-scale construction. Generally, existing scaffolding usually includes a supporting tripod, on which a working platform is fixedly connected. Users can climb onto the working platform through the crossbar on the supporting tripod to work on the working platform. However, existing scaffolding is often spliced ​​together through frames, so that the overall size of the scaffolding is fixed. The horizontal height of the supporting tripod cannot be adjusted, so the construction height of the working platform is fixed; users cannot reasonably adjust the construction height, and the versatility is poor. At the same time, there is often no area on the scaffolding to place tools, so tools are easy to fall from the working platform, and the function is relatively single. Therefore, it is necessary to design a multifunctional scaffolding to overcome the above difficulties. Summary of the invention

[0003] The utility model designs a multifunctional scaffolding in view of the problems existing in the prior art. The utility model is provided with a plurality of lifting platforms which can adjust the height relative to the scaffolding assembly. The lifting platforms can be used as supporting platforms and storage platforms, and have good versatility. The locking structure is stable and reliable when locked by the first elastic locking device.

[0004] The invention objective of the utility model is achieved through the following technical solutions: a multifunctional scaffolding, comprising tripod assemblies arranged in pairs, a plurality of lifting platforms connecting the two tripod assemblies are provided between the two tripod assemblies; a first elastic locking device for locking the two is provided between the lifting platform and the tripod assemblies; the lifting platform comprises side frames arranged in pairs, a support frame fixedly connected to the two is provided between the two side frames, a support plate detachably connected to the support frame is provided on the support frame, a rotating stretching locking device for locking is provided between the support plate and the support frame; the lifting platform sliding sleeve is installed on the tripod assemblies, a roller assembly detachably connected to the tripod assemblies is provided on the tripod assemblies, and a second elastic locking device for locking the two is provided between the roller assembly and the tripod assembly.

[0005] Preferably, the tripod assembly includes vertical connecting rods arranged in pairs, and a plurality of cross bars connecting the two vertical connecting rods are provided between the two vertical connecting rods; each of the cross bars is arranged side by side and adjacent to each other, and each of the cross bars is eccentrically arranged with respect to the vertical connecting rod; a plurality of locking holes arranged side by side and adjacent to each other are provided on the vertical connecting rod; the two ends of the side frame are slidably sleeved and installed on the vertical connecting rod, and a first elastic locking device for locking the side frame and the vertical connecting rod is provided between the side frame and the vertical connecting rod.

[0006] By setting the crossbar, it is convenient for the operator to climb onto the lifting platform to work; each of the crossbars is eccentrically arranged with the vertical connecting rod, so that the center of gravity of the climber is more stable and the climbing process is safer. By setting a plurality of locking holes on the vertical crossbar, it is convenient to install the first elastic locking device, so that the lifting platform can be set at a reasonable horizontal height.

[0007] Preferably, the side frame includes a U-shaped connecting rod, which is sleeved on the outer layer of the vertical connecting rod; a mounting seat and a positioning hole are provided on the U-shaped connecting rod, and a first elastic locking device is provided between the mounting seat and the positioning hole; the first elastic locking device includes a handle and a first limit pin arranged in a pair, and a first elastic member is also provided on the handle; the handle is inserted into the mounting seat and the positioning hole, and the handle is arranged toward the locking hole; a first limit pin is fixedly connected to the handle, and the first elastic member is sleeved and installed on the handle, one end of the first elastic member abuts against the first limit pin, and the other end of the first elastic member abuts against the inner wall of the mounting seat.

[0008] By setting a U-shaped connecting rod, it is convenient to assemble the side frame from the side and the tripod assembly, and then lock it through the first elastic locking device. After the side frame is installed, the support frame is fixed to the side frame by fastening screws, and the assembly is convenient and quick. In the default state, the end of the handle is stuck in the positioning hole and the locking hole, so that the first elastic locking device is in a locked state and the lifting platform cannot move up and down. When the horizontal height of the lifting platform needs to be adjusted, the operator pulls the handle to disengage it from the locking hole, and the first elastic member is in a further compressed state; after adjusting the height of the lifting platform, align the positioning hole and the locking hole, and when the handle is released, the end of the handle will automatically be stuck in the locking hole, so that the lifting platform can be stably maintained at the corresponding height.

[0009] Preferably, the U-shaped connecting rod is provided with a plurality of second hole positions, and the second hole positions are arranged on both sides of the mounting seat; a detachable second elastic locking device is provided between the second hole position and the locking hole position; the second elastic locking device includes a locking pin and an elastic body, and the locking pin is inserted in the second hole position and the locking hole position, one end of the elastic body is hinged to one end of the locking pin, and the other end of the elastic body is inserted in the other end of the locking pin; when the end of the elastic body is stuck on the locking pin, the elastic body rests on the outer wall of the U-shaped connecting rod.

[0010] The U-shaped connecting rod is also provided with a second hole position, so that the lifting platform can be locked by installing a second elastic locking device in the second hole position and the locking hole position. When the lifting platform is in a low position, the lifting platform is often used to place items, so that the lifting platform is less stressed, and the lifting platform can be locked separately by the second elastic locking device. Insert the locking pin into the second hole position and the locking hole position, and then rotate the elastic body and insert it into the end of the locking pin, so that the locking pin cannot move, thereby locking the lifting platform. When the lifting platform is in a high position, a standing operator is often required on the lifting platform, so that the lifting platform is subjected to greater stress. Since the second elastic locking device is detachably connected, after the first elastic locking device is installed between the lifting platform and the tripod assembly, the second elastic locking device can be installed, so that the locking of the lifting platform is more stable and reliable.

[0011] Preferably, the side frames are provided with stretchable handrails arranged in pairs, and the lifting platform can be installed on the tripod assembly on both sides.

[0012] When the operator needs to adjust the height of the lifting platform, the lifting platform can be moved by stretching the handrail, which makes the operation more labor-saving.

[0014] The support frame and the support plate are detachably connected. When the support plate is placed in the limiting groove, it cannot move relative to the support frame. Then, it is locked by rotating the stretch locking device, so that the support plate can be firmly installed on the support frame. In the default state, the rotating stretch locking device is in a locked state. When it is necessary to unlock, push the limiting rod upward so that the limiting protrusion will move away from the sinking groove, and then rotate the limiting rod to turn the limiting protrusion, so that the limiting protrusion is completely out of the sinking groove, and the support plate can be removed. When the limiting rod is pushed upward, the second elastic member is in a further compressed state. When the support plate needs to be re-locked, place the support plate in the limiting groove; then push the limiting rod upward, and rotate the limiting rod to align the limiting protrusion with the sinking groove, and then release the limiting rod, so that the limiting protrusion will automatically be stuck in the sinking groove, and the rotating stretch locking device is in a locked state. A clearance notch is set on the side frame to facilitate the installation of the limiting sleeve under the bar hole.

[0015] Preferably, the limiting sleeve is hollow, and the outer diameter of the limiting sleeve is larger than the width of the strip hole; the outer diameter of the second elastic member is smaller than the outer diameter of the limiting sleeve, one end of the second elastic member abuts against the bottom of the limiting sleeve, and the other end of the second elastic member abuts against the second limiting pin arranged adjacent to it; the outer contour of the limiting protrusion and the outer contour of the sunken groove match each other; when the limiting protrusion and the upper end surface of the support plate are flush, the rotation and stretching locking device is in a locked state.

[0016] By providing the limiting sleeve and the second limiting pin, the second elastic member can stably generate elastic force, which is convenient for controlling the extension and retraction of the limiting rod. When the limiting protrusion is flush with the upper end surface of the support plate, the rotation stretching locking device is in a locked state, so that the operator will not be stuck by the limiting protrusion when working on the support plate, and the construction is safer.

[0017] Preferably, the tripod assembly is provided with a roller assembly detachably connected thereto, and the tripod assembly is provided with a locking hole through which a second elastic locking device is inserted; the second elastic locking device comprises a locking pin and an elastomer, the locking pin is inserted in the locking hole, one end of the elastomer is hinged to one end of the locking pin, and the other end of the elastomer is inserted in the other end of the locking pin; when the locking pin is inserted into the tripod assembly and the roller assembly at the same time, the end of the elastomer abuts against the outer wall of the tripod assembly.

[0018] By arranging a detachable roller assembly on the tripod assembly, the scaffold is convenient to move. When the roller assembly needs to be locked, the locking pin is inserted into the locking hole and then clamped at the end of the locking pin through the elastic body, so that the locking pin cannot move relative to the locking hole, and the roller assembly is reliably connected to the tripod assembly.

[0019] Preferably, a locking screw for locking is further provided between the tripod assembly and the roller assembly; a first through hole for installing the locking screw is provided on the tripod assembly, and the first through hole and the locking hole are arranged perpendicular to each other; the locking screw and the first through hole are threadedly connected, and when the locking screw is locked, the end of the locking screw abuts against the locking pin.

[0020] The locking screw is rotated to make the end of the locking screw abut against the locking pin to prevent the locking pin from sliding. In this way, after the second elastic locking device and the locking screw cooperate, the connection of the roller assembly is more stable and reliable.

The lifting platform and the tripod assembly are locked by a first elastic locking device, which is convenient for disassembly and assembly, and the locking is reliable. Since the lifting platform is slidably connected to the tripod assembly, and the lifting platform can be installed on both sides; in this way, the upper lifting platform is used as a supporting platform, and the lower lifting platform is used as a storage platform, which has better versatility. At the same time, the support plate on the support frame is detachably connected, and is easy to assemble. The support plate is locked by rotating the stretching locking device, and the connection between the support plate and the support frame is more stable and reliable. A roller assembly detachably connected to the tripod assembly is provided at the end of the tripod assembly, and the roller assembly is connected to the tripod assembly by a second elastic locking device and a locking screw, and the roller assembly has a good locking effect, and is safer and more reliable to use.

[0038] The specific operation process of this embodiment is as follows. When the scaffolding is needed, the tripod assembly 1 and the lifting platform 2 are assembled. In this embodiment, two lifting platforms 2 are installed on the tripod assembly 1; the upper lifting platform 2 is installed forward, and the lower lifting platform 2 is installed reversely. When installing the lifting platform 2, first set the U-shaped connecting rod 211 to be clamped on the outer wall of the vertical connecting rod 101, so that it is convenient to assemble the side frame 21 with the tripod assembly 1 from the side, and then lock it through the first elastic locking device 3. After the side frame 21 is installed, the support frame 22 is fixed to the side frame 21 by tightening screws, and the assembly is convenient and quick. In the default state, the end of the handle 31 is clamped in the positioning hole 213 and the locking hole 7, so that the first elastic locking device 3 is in a locked state, and the lifting platform 2 cannot move up and down. When it is necessary to adjust the horizontal height of the lifting platform 2, the operator pulls the handle 31 to disengage it from the locking hole 7, and the first elastic member 33 is in a further compressed state; after adjusting the height of the lifting platform 2, the positioning hole 213 and the locking hole 7 are aligned, and when the handle 31 is released, the end of the handle 31 will automatically snap into the locking hole 7, thereby allowing the lifting platform 2 to be stably maintained at the corresponding height.

Because the second elastic locking device 6 is detachably connected, after the first elastic locking device 3 is installed between the lifting platform 2 and the tripod assembly 1, the second elastic locking device 6 can be installed again, so that the locking of the lifting platform 2 is more stable and reliable.

Then, the support plate 23 is locked by rotating the stretching locking device 4, so that the support plate 23 can be firmly installed on the support frame 22. In the default state, the rotating stretching locking device 4 is in a locked state. When unlocking is required, the limiting rod 41 is pushed upward, so that the limiting protrusion 42 will be away from the sinking groove 26, and then the limiting rod 41 is rotated to turn the limiting protrusion 42, so that the limiting protrusion 42 is completely separated from the sinking groove 26, and the support plate 23 can be removed. When the limiting rod 41 is pushed upward, the second elastic member 45 is in a further compressed state. When it is necessary to re-lock the support plate 23, place the support plate 23 in the limiting groove 25; then push the limiting rod 41 upward, and rotate the limiting rod 41 to align the limiting protrusion 42 with the sunken groove 26, and then release the limiting rod 41, so that the limiting protrusion 42 will automatically be stuck in the sunken groove 26, and the rotating stretch locking device 4 is in a locked state.
