Description

Technical Field

[0001] This invention relates to the field of scaffolding technology, and specifically to a scaffolding with dual-switching foot supports and its method of use. Background Technology

[0002] Scaffolding provides construction workers with a temporary platform for work and is most commonly used for building construction, cleaning, lighting maintenance, and equipment upkeep. The overall structure uses a modular design, with standardized components and no loose parts. No installation tools are required, and two workers can assemble a high-altitude work platform in a short time. Aluminum alloy scaffolding is widely used in the construction industry due to its advantages such as light weight, quick assembly and disassembly, high flexibility, and long service life.

[0003] However, conventional scaffolding usually has rollers at the bottom, which makes it easy to move the scaffolding on the ground. During construction, although the rollers are in a stopped state, they only contact the ground at a point on the arc. The structure is not very stable, sways a lot, and has poor safety. Moreover, the higher the scaffolding is, the greater the safety hazard. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a scaffold with dual switching foot supports and its usage method, which solves the problems of existing scaffolds having a small contact area with the ground, weak structural stability, large swaying, and poor safety during use.

[0005] The technical solution to achieve the above objectives is:

[0006] This invention provides a scaffold with dual-switching foot supports, comprising:

[0007] Scaffold body;

[0008] A working platform mounted on the scaffold body;

[0009] Four supports are located at the four corners of the bottom of the scaffold body. Each support includes a rolling roller and a foot pad. The height of the foot pad is adjustable. By adjusting the height of the foot pad, the roller or the foot pad can be made to contact the ground.

[0010] Specifically, the foot support also includes a fixed plate and a U-shaped frame. The fixed plate is fixed to the bottom of the scaffold body, and the U-shaped frame is rotatably disposed at the bottom of the fixed plate with its opening facing downward. A rotating shaft is rotatably disposed on the central axis of the roller, and the two ends of the rotating shaft are respectively fixed to the two ends of the U-shaped frame.

[0011] Furthermore, it also includes:

[0012] A U-shaped foot pedal, with hinge plates at both ends, the upper sides of which are hinged to the U-shaped frame;

[0013] Two curved connecting rods are located on both sides of the roller, with one end hinged to the roller's pivot. The other end of the two curved connecting rods is hinged to a straight connecting rod. The end of the straight connecting rod away from the curved connecting rod is hinged to the lower side of the hinge plate of the foot pedal.

[0014] The foot pad is located between two straight connecting rods. By moving the middle of the foot pad pedal up or down, the foot pad pedal moves the foot pad up or down through the straight connecting rods, thereby adjusting the height of the foot pad.

[0015] Furthermore, it also includes a U-shaped roller pedal, with both ends of the roller pedal located on both sides of the roller and inside the U-shaped frame. The two ends of the roller pedal are provided with arc-shaped plates, the inner arc surface of which abuts against the rotation axis of the roller, and one end of the arc-shaped plate is hinged to the hinge point between the straight connecting rod and the hinge plate. By pushing the middle of the roller pedal downward, the inner arc surface of the arc-shaped plate slides relative to the rotation axis of the roller, thereby causing the arc-shaped plate to drive the foot upward through the straight connecting rod, so as to adjust the height of the foot.

[0016] Furthermore, limit rods are anchored into both hinge plates of the foot pedal, and the anchoring depth of the limit rods is adjustable. Each side of the U-shaped frame has two limit holes for the insertion of the limit rods, and the two limit holes are spaced apart.

[0017] When the limiting rod is inserted into a corresponding limiting hole, the height of the pad is higher than the height of the roller;

[0018] When the limit rod is inserted into another limit hole, the pad rests against the ground.

[0019] Furthermore, the foot pad includes:

[0020] A support plate fixed between two straight connecting rods;

[0021] A threaded rod threadedly connected to the support plate;

[0022] A pad is fixed to the lower end of the threaded rod, and the pad is supported on the ground.

[0023] The present invention also provides a method for using a scaffold with dual switching supports, comprising the following steps:

[0024] Provide scaffolding as described above;

[0025] The workers adjusted the height of the footrests to be higher than the height of the rollers, and then pushed the scaffold body to the position to be constructed.

[0026] After moving the scaffold body to the construction location, the workers lower the height of the footrests so that they are in contact with the ground, thereby preventing the scaffold body from moving.

[0027] Furthermore, after the pad makes contact with the ground, the operator continues to lower the height of the pad, stopping the adjustment once the roller leaves the ground.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1) Install foot supports at the four corners of the bottom of the scaffold body. The foot supports include rollers and height-adjustable pads. By adjusting the height of the pads, the pads can be supported on the ground or lifted off the ground. During construction, the pads support the scaffold body on the ground. When moving, the pads lift off the ground to allow the rollers to rotate freely.

[0030] 2) Install diagonal support frames at the four corners of the side of the scaffold body. During construction, the diagonal support frames support the ground, thereby further supporting the scaffold body and improving its stability.

[0031] 3) The support base consists of a support plate, a threaded rod, and a base plate. Before using the base plate for support, adjust the relative position of the threaded rod and the support plate so that the rollers can lift off the ground after the base plate is in place. Alternatively, after the base plate is in place, adjust the relative position of the threaded rod and the support plate to lift the rollers off the ground, thereby preventing the rollers from continuing to move the scaffold body.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] See Figure 1 This invention provides a scaffold with dual-switching foot supports and its usage method, solving the problems of existing scaffolds having a small contact area with the ground, weak structural stability, large swaying, and poor safety during use. 1) Foot supports are installed at the four corners of the bottom of the scaffold body. Each foot support includes rollers and height-adjustable pads. By adjusting the height of the pads, they can be supported on the ground or lifted off the ground. During construction, the pads support the scaffold body on the ground; when moving, the pads lift off the ground, allowing the rollers to rotate freely.

[0040] 2) Install diagonal support frames at the four corners of the side of the scaffold body. During construction, the diagonal support frames support the ground, thereby further supporting the scaffold body and improving its stability.

[0041] 3) The support base consists of a support plate, a threaded rod, and a base plate. Before using the base plate for support, adjust the relative position of the threaded rod and the support plate so that the rollers can lift off the ground after the base plate is in place. Alternatively, after the base plate is in place, adjust the relative position of the threaded rod and the support plate to lift the rollers off the ground, thereby preventing the rollers from continuing to move the scaffold body.

[0042] The following description, in conjunction with the accompanying drawings, illustrates a scaffold with dual-switching foot supports and its method of use.

[0043] See Figure 1 This diagram shows the overall structure of the scaffolding with dual switching supports according to the present invention. (See attached diagram.) Figure 3 This image shows a schematic diagram of the scaffolding support structure of the present invention, which features dual-switching support legs. The following is in conjunction with... Figure 1 and Figure 3 This invention describes a scaffold with dual-switching foot supports and its method of use.

[0044] like Figure 1 and Figure 3As shown, a scaffold with dual-switching foot supports according to the present invention includes: a scaffold body 1; a working platform 2 disposed on the scaffold body 1; and four foot supports 3 respectively located at the four corners of the bottom of the scaffold body 1. Each foot support 3 includes a rollable roller 31 and a foot pad. The height of the foot pad can be adjusted. By adjusting the height of the foot pad, the roller 31 can be in contact with the ground or the foot pad can be in contact with the ground.

[0045] Specifically, the work platform 2 is located on top of the scaffold body 1, and the work platform 2 is surrounded by a fence.

[0046] In one specific embodiment, the foot support 3 further includes a fixing plate 33 and a U-shaped frame 34. The fixing plate 33 is fixed to the bottom of the scaffold body 1. The U-shaped frame 34 is rotatably disposed at the bottom of the fixing plate 33 with its opening facing downward. A rotating shaft is rotatably disposed on the central axis of the roller 31. The two ends of the rotating shaft are respectively fixed to the two ends of the U-shaped frame 34.

[0047] Specifically, the bottom of the scaffold body 1 is horizontally provided with an installation plate that is compatible with the fixing plate 33. The fixing plate 33 is located at the bottom of the installation plate and is connected by bolts.

[0048] In one specific embodiment, it further includes: a U-shaped foot pedal 36, with hinge plates at both ends of the foot pedal 36, the upper sides of which are hinged to the U-shaped frame 34; two bent connecting rods 38, located on both sides of the roller 31 respectively, with one end hinged to the rotating shaft of the roller 31, and the other end of the two bent connecting rods 38 hinged to a straight connecting rod 37, the end of the straight connecting rod 37 away from the bent connecting rod 38 being hinged to the lower side of the hinge plate of the foot pedal 36; the foot pad is located between the two straight connecting rods 37, and by moving the middle of the foot pedal 36 up or down, the foot pedal 36 drives the foot pad to move up or down through the straight connecting rods 37, thereby realizing the adjustment of the height of the foot pad.

[0049] Specifically, a first hinge rod 310 is provided through the upper end of the hinge plate of the foot pedal 36. The first hinge rod 310 passes through the U-shaped frame 34, and the foot pedal 36 and the U-shaped frame 34 are hinged together by the first hinge rod 310. A second hinge rod 311 is provided at the hinge point of the straight connecting rod 37 and the bent connecting rod 38, and the straight connecting rod 37 and the bent connecting rod 38 are hinged together by the second hinge rod 311.

[0050] Specifically, the length of the straight connecting rod 37 is less than the length of the bent connecting rod 38.

[0051] In one specific embodiment, a U-shaped roller pedal 35 is also included. The two ends of the roller pedal 35 are located on both sides of the roller 31 and inside the U-shaped frame 34. Arc-shaped plates are provided at both ends of the roller pedal 35. The inner arc surface of the arc-shaped plate abuts against the rotation axis of the roller 31, and one end of the arc-shaped plate is hinged to the hinge point between the straight connecting rod 37 and the hinge plate. By pushing the middle of the roller pedal 35 downwards, the inner arc surface of the arc-shaped plate slides relative to the rotation axis of the roller 31, thereby causing the arc-shaped plate to drive the foot pad upwards via the straight connecting rod 37, thus adjusting the height of the foot pad. When adjusting the height of the foot pad, the foot pad pedal 36 needs to be pushed upwards. Since the distance between the middle of the foot pad pedal 36 and the ground is small, pushing it upwards is not as convenient as pushing it downwards. Therefore, the roller pedal 35 can be pushed downwards to achieve the same effect of adjusting the height of the foot pad. When the roller pedal 35 is pushed down, the middle part of the foot pad pedal 36 moves upward simultaneously. When the height of the middle part of the roller pedal 35 is the same as the height of the foot pad pedal 36, the roller pedal 35 is located inside the foot pad pedal 36. At this time, the middle part of the foot pad pedal 36 has a sufficient distance from the ground, and then the middle part of the foot pad pedal 36 moves upward to prevent the foot pad pedal 36 from interfering with the roller pedal 35.

[0052] Specifically, a third hinge rod 312 is provided at the hinge joint of the roller pedal 35, the foot pedal 36, and the straight connecting rod 37, and the three are hinged together by the third hinge rod 312.

[0053] Preferably, both the roller pedal 35 and the foot pedal 36 have foot pedals in the middle. The top and bottom surfaces of the foot pedals are provided with anti-slip strips.

[0054] In one specific embodiment, limit rods 313 are anchored into both hinge plates of the foot pad 36. The anchoring depth of the limit rods 313 is adjustable. Each side of the U-shaped frame 34 has two limit holes for the insertion of the limit rods 313, and the two limit holes are spaced apart. When the limit rod 313 is inserted into one of the corresponding limit holes, the height of the foot pad is higher than the height of the roller 31. When the limit rod 313 is inserted into the other limit hole, the foot pad rests against the ground.

[0055] Preferably, the limit rod 313 is an indexing pin.

[0056] Preferably, a spring is fitted on the limiting rod 313, and the spring provides a force for the limiting rod 313 to move inward, preventing the limiting pin 313 from falling out of the corresponding limiting hole.

[0057] In one specific embodiment, the pad includes: a support plate 314 fixed between two straight connecting rods 37; a threaded rod 39 threadedly connected to the support plate 314; and a pad 32 fixed to the lower end of the threaded rod 39, the pad 32 supporting the ground. Two nuts are provided on the threaded rod 39, located on the upper and lower sides of the support plate 314 respectively. The distance between the support plate 314 and the pad 32 is adjusted by adjusting the two nuts. The pad 32 is perpendicular to the threaded rod 39, and when the pad 32 is horizontally against the ground, the threaded rod 39 remains vertical, and a limiting rod 313 is inserted into the corresponding limiting hole. After the limiting rod 313 is locked in the corresponding limiting hole, if the ground is uneven and the pad 32 does not contact the ground, the nuts are adjusted to adjust the height of the pad 32 upwards or downwards, thereby bringing the pad 32 into contact with the ground.

[0058] Preferably, by adjusting the nut, the distance between the pad 32 and the support plate 314 is increased. After the limit rod 313 is inserted into the corresponding limit hole, when the pad 32 is supported on the ground, the roller 31 can be lifted off the ground, thereby preventing the roller 31 from continuing to roll.

[0059] Specifically, reinforcing ribs are provided on the outer sides of both ends of the foot pedal 36 and the outer sides of both ends of the roller pedal 35.

[0060] In one specific embodiment, it also includes four inclined support frames 4 located at the four corners of the side of the scaffold body 1.

[0061] Specifically, the inclined support frame 4 includes long and short inclined braces. The upper ends of both the long and short inclined braces are hinged with collars, which are movably fitted onto the scaffold body 31. The lower end of the short inclined brace is hinged to the long inclined brace, and the lower end of the long inclined brace is provided with a support foot for ground support. By setting up the long and short inclined braces, the angle between them can be adjusted, thereby adjusting the height of the support foot at the lower end of the long inclined brace. During construction, the support foot rests against the ground, and by supporting the long inclined brace with its support foot on the ground, the scaffold body 31 is further supported, ensuring its stability.

[0062] The present invention also provides a method for using a scaffold with dual switching supports, comprising the following steps:

[0063] Provide scaffolding as described above;

[0064] Personnel adjust the height of the footrests to be higher than the height of the rollers 31, and push the scaffold body 1 to the position to be constructed.

[0065] After moving the scaffold body 1 to the construction position, the personnel lower the height of the foot pads so that they are in contact with the ground, thereby preventing the scaffold body 1 from moving.

[0066] In one specific embodiment, after the foot contacts the ground, the person continues to lower the height of the foot, and stops adjusting after the roller 31 leaves the ground.

[0067] The following is a detailed description of the use of a scaffold with dual switching supports according to the present invention.

[0068] The operator moves the footrest 36 upwards, raising the height of the footrest via the connecting rod 37, thus lifting the footrest 36 off the ground. Alternatively, the operator moves the roller pedal 35 downwards, causing the inner arc surface of the curved rod on the roller pedal 35 to slide relative to the axis of rotation of the roller 31, and moving the footrest upwards via the connecting rod 37. Once the footrest is raised to the designated height, the limiting rod 313 on the footrest 36 is inserted into the corresponding limiting hole to lock the footrest.

[0069] Then the personnel pushed the scaffold body 1 to the construction position.

[0070] After being pushed to the construction position, the personnel pull out the limiting rod 313 to disengage it from the limiting hole, and then push the foot pedal 36 downward to move the foot pedal 36 downward through the straight connecting rod 37 and make the foot contact the ground. Then, the limiting rod 313 is inserted into the corresponding limiting hole.

[0071] When the ground is uneven, personnel can adjust the nut to move the threaded rod 39 up or down, so that the pad 32 moves up or down and comes into contact with the ground.

[0072] After the pad 32 contacts the ground, personnel can adjust the nut to move the threaded rod 39 downwards, thereby moving the pad 32 downwards. However, since the pad 32 is in contact with the ground, the roller 31 and the scaffold body 1 will move upwards, causing the roller 31 to detach from the ground, thus preventing the roller 31 from moving the scaffold body 1 due to rolling. Alternatively, the position of the pad 32 can be adjusted before it contacts the ground. After moving the foot pedal 36 to make the pad 32 fit against the ground, the roller 31 can detach from the ground.

[0073] After the pad 32 contacts the ground, the personnel adjust the inclined support frame 4 so that the lower foot of the long inclined brace contacts the ground, thereby increasing the stability of the scaffold body 1.

[0074] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
