Description

Technical Field

[0001] The invention relates to the technical field of scaffolding, in particular to a disc-type scaffolding system. Background Art

[0002] The disc-type scaffold is a common scaffold used in construction. Its structure is mainly composed of vertical poles, horizontal poles and disc-type connectors. Through the disc-type connectors, a stable structure is formed, which can withstand large loads. The disc-type scaffold can also freely adjust the height and layout according to construction needs to adapt to various construction environments. In order to ensure safety and stability, the latch of the disc-type scaffold usually needs to be hit with a hammer to enhance the fixation of the latch during installation. In the prior art, when setting up a scaffold, workers at a lower position usually manually hand over the rod-shaped parts of the scaffold to workers at a higher position. However, due to the heavy weight of the rod-shaped parts, workers will be very strenuous in the process of handing them over, so that workers can easily make the rod-shaped parts touch the erected scaffold. If the installed latch is accidentally touched and not checked in time, the latch will be affected by external force, thereby affecting its fixed state, thereby reducing the stability of the scaffold and increasing the risk of collapse.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0022] like Figures 1 to 7As shown, a disc-type scaffolding system proposed by the present invention includes a scaffolding body 1 and a plurality of vertical poles 11 arranged on the scaffolding body 1. A springboard is also provided on the scaffolding body 1 for workers to step on. The vertical pole 11 is the main vertical supporting force-bearing member of the whole system. The upper and lower ends of the vertical pole 11 are provided with a lower support 14 and an upper support 15 corresponding to each other. The lower support 14 and the upper support 15 are used to adjust the height to adapt to the foundation and the building elevation. A plurality of chucks 2 opposite to each other are fixedly sleeved on the vertical pole 11. The middle part of the chuck 2 is installed with a cross bar 12 and a diagonal brace 13. The cross bar 12 is connected to the horizontal rod between the vertical poles 11, and forms a lattice with the vertical poles 11 to enhance the bearing capacity of the vertical poles. The diagonal brace 13 is connected to the diagonal of the vertical lattice of the frame body, and forms a triangular lattice with the vertical poles 11 and the cross bar 12, so that the frame body is more stable vertically. The ends of the cross bar 12 and the diagonal rod 13 are fixed to the chuck 2 by the fixed pin 3, and also include: a buckle mechanism installed at the bottom of the fixed pin 3 so that the cross bar 12 and the diagonal rod 13 fixed on the chuck 2 cannot be separated; a resisting mechanism, which is slidably connected to the top of the fixed pin 3 and can be opened by a manual pressing mechanism; a locking mechanism, which is arranged at the inner top of the fixed pin 3 and is used to clamp the opened resisting mechanism.

[0023] Further, the buckle mechanism includes a pair of driving push pieces 5 arranged in the fixed plug 3, a pair of limiting sliding grooves 52 are provided on the driving push piece 5, a pair of limiting support rods 4 supporting the sliding of the driving push piece 5 are fixedly connected inside the fixed plug 3, and a reset spring 51 is provided in the middle of the driving push piece 5. The reset spring 51 is used to make the driving push piece 5, which is not received and stretched, produce a gap for the insertion of the separation plug 314 under normal conditions. It will drive the corresponding sliding protrusion 34 to retract into the fixed plug 3. The side of the driving push piece 5 away from the reset spring 51 is fixedly connected with a sliding protrusion 34 that movably penetrates the fixed plug 3. The sliding protrusion 34 is used to clamp the first connector 121 or the second connector 131 that passes through to achieve fixation after being clamped. The pair of sliding protrusions 34 and the reset spring 51 are located on the same axis.

[0024] The abutting mechanism includes a button 31 slidably connected to the top of the fixed plug 3, and the end of the button 31 inserted into the fixed plug 3 is fixedly connected to the abutting plug rod 313, and the end of the abutting plug rod 313 away from the button 31 is provided with a separation plug 314 for abutting against a pair of driving push pieces 5 to make them open. The separation plug 314, as the name implies, abuts against a pair of driving push pieces 5 and then spreads them apart. The outer wall of the button 31 inserted into the fixed plug 3 is fixedly connected to a pair of support blocks 311, and the support blocks 311 are fixedly connected to the pull spring 312. The pull spring 312 is to make the button 31 that is not stuck by the locking mechanism automatically slip out of the fixed plug 3, and finally the pair of sliding protrusions 34 retract into the fixed plug 3, so that the fixed plug 3 is not hindered when the first connector 121 or the second connector 131 slips out. The end of the pulling spring 312 away from the supporting block 311 is fixedly connected to the inner wall of the fixed pin 3, and the top inner wall of the fixed pin 3 is fixedly connected with a supporting socket 6. The end of the supporting socket 6 close to the button 31 is provided with a supporting groove 61 for supporting the sliding of the button 31. The supporting groove 61 prevents the sliding direction of the button 31 from deviating.

[0025] Secondly, the locking mechanism includes a rectangular slot 39 provided at the top of the fixed latch 3, a driving block 35 is slidably connected inside the rectangular slot 39, a plurality of linearly arranged tooth grooves 38 are provided on the button 31, and a latching tooth 36 is fixedly connected to the end of the driving block 35 close to the button 31, which can prevent the button 31 from moving upwards but does not hinder the button 31 from moving downwards after being stuck in the tooth groove 38. When the button 31 moves into the fixed latch 3, the latching tooth 36 will not be stuck in the tooth groove 38, but when the button 31 moves out of the fixed latch 3, the latching tooth 36 will be stuck in the tooth groove 38. A push spring 37 is fixedly connected to the end of the driving block 35 away from the latching tooth 36, and the push spring 37 is used to restore the manually moved sliding block 32 to its original position, so that the sliding block 32 can be used repeatedly. The end of the push spring 37 away from the driving block 35 is fixedly connected to the inner wall of the fixed latch 3.

[0026] Furthermore, a sliding block 32 is provided at the top of the fixed pin 3, which is located just above the rectangular slide groove 39. The lower surface of the sliding block 32 is fixedly connected to the top of the driving block 35. The upper surface of the sliding block 32 is provided with a pressing groove 33 for a finger to be inserted into. The pressing groove 33 allows a finger to be inserted, thereby increasing the friction between the finger and the sliding block 32, thereby making manual sliding of the sliding block 32 easier and more labor-saving.

[0027] Furthermore, the chuck 2 is provided with a plurality of first clamping holes 21 and second clamping holes 22 distributed in a circumferential array for inserting the fixing pin 3, and the first clamping holes 21 and the second clamping holes 22 are used for connecting the corresponding first connectors 121 and the second connectors 131. Both ends of the crossbar 12 are fixedly connected with the first connectors 121, and the first connectors 121 are provided with first plugging holes 122 corresponding to the second clamping holes 22 and for inserting the fixing pin 3, and both ends of the inclined rod 13 are rotatably connected with the second connectors 131, and the second connectors 131 are provided with second plugging holes 132 corresponding to the first clamping holes 21 and for inserting the fixing pin 3.

[0028] In this embodiment, when the disc-type scaffolding system is needed, the vertical poles 11, the horizontal poles 12, the diagonal braces 13, the lower supports 14 and the upper supports 15 on the scaffolding body 1 are connected as shown in FIG. Figure 1 During the erection process, when the first connector 121 at the end of the crossbar 12 and the second connector 131 at the end of the inclined rod 13 need to be firmly mounted on the chuck 2 by the fixing pin 3, it is only necessary to overlap the first plug hole 122 on the first connector 121 with the second plug hole 22 on the chuck 2, and overlap the second plug hole 132 on the second connector 131 with the first plug hole 21 on the chuck 2. After that, the end of the fixing pin 3 away from the button 31 can be inserted into the first plug hole 122 and the second plug hole 22 or the second plug hole 132 and the first plug hole 21 in sequence, as shown in FIG. Figure 2 As shown, by pressing the button 31, the button 31 drives the push rod 313 to move, and the push rod 313 drives the separation plug 314 to press against the middle of a pair of push plates 5 to open the push plates 5. Figure 4 As shown, at this time, the driving push pieces 5 drive the corresponding sliding protrusions 34 to disengage from the fixed plug 3. Later, when the button 31 wants to move upward, the driving block 35 drives the latching teeth 36 to engage in the tooth grooves 38 on the button 31 through the elastic thrust of the push spring 37, so that the button 31 cannot move upward. Then, the separating plug 314 at the end of the abutting plug rod 313 can be stuck between the pair of driving push pieces 5, so that the pair of sliding protrusions 34 protrude out of the fixed plug 3, so that the sliding protrusions 34 are stuck in the first connector 121 or the second connector 131 that passes through and cannot be disengaged; When the fixing pin 3 needs to be removed from the first connector 121 and the second connector 131, one only needs to insert a finger into the pressing groove 33 at the top of the sliding block 32 and push the sliding block 32, so that the sliding block 32 moves away from the button 31. The sliding block 32 drives the driving block 35 and the latching teeth 36 to move in sequence, so that the latching teeth 36 are removed from the inserted tooth grooves 38. At this time, the button 31 can be pulled out of the fixing pin 3 by the elastic pulling force of a pair of pulling springs 312, so that the supporting block 311 drives the button 31 to be removed from the fixing pin 3. Finally, the button 31 drives the abutting plug rod 313 and the separating plug 314 to disengage from the middle of the pair of driving push pieces 5 in turn. At this time, the pair of driving push pieces 5 can drive the corresponding sliding protrusions 34 to retract into the fixed pin 3 through the elastic pulling force of the central return spring 51, so that the fixed pin 3 can be moved upward to disengage the first connector 121 and the second connector 131. Finally, the first connector 121 and the second connector 131 can be removed from the chuck 2, saving time and effort.
