Abstract
Description
Technical Field
[0001] This application relates to the field of engineering construction, and more specifically, to an engineering anti-tipping platform. Background Technology
[0002] Construction engineering refers to the engineering entity formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Currently, in some building construction projects, the working height is exceeded, and some construction platform devices are needed to assist in the completion. Traditional construction platforms are usually equipped with casters at the bottom for easy movement. After moving to the construction position, the casters are locked for construction. However, the contact area between the casters and the ground is small. When heavy goods are placed on the platform, the ground may sink, causing the platform to become unstable.
[0003] To solve the above problems, a support frame is usually set up on the construction platform to support the platform. To facilitate movement, the support frame is usually designed to be foldable. When the construction platform is moved to the construction position, the support frame is unfolded to provide support. To ensure the support effect, multiple supports are usually set up. However, the ground may be uneven, so multiple supports need to be unfolded separately and made to ensure that the supports are in contact with the ground for support, which is inconvenient to use.
[0004] Therefore, an engineering anti-tipping platform is needed to solve the above problems. Utility Model Content
[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide an engineering anti-tipping platform, comprising: a base; a base with movable wheels at its lower end and an inner cavity inside the base; a lifting platform; a platform disposed on the upper side of the base and connected via a scissor-type lifting structure; four sets of support rods circumferentially disposed on the base, one end of which is rotatably disposed on the base and supports the base by flipping; a release assembly for driving the support rods to flip and support the base; the release assembly includes: a sliding sleeve slidably disposed within the base; a retaining ring fixed to both ends of the sliding sleeve; a sliding member slidably disposed within the base, with a first steel wire and a second steel wire fixedly connected to the sliding member; a connecting spring, both ends of which are fixedly connected to the retaining ring at the lower end of the sliding sleeve and the sliding member, respectively; and a rotating shaft end, with two coaxially arranged members fixedly disposed on the support rod, the rotating shaft end rotatingly engaging with the base, and the support rod unfolding and folding by rotating around the rotating shaft end; wherein the first steel wire and the second steel wire are respectively wound around the two rotating shaft ends, and one end is fixedly connected to the rotating shaft end, and the first steel wire and the second steel wire are wound in opposite directions.
[0007] With the support rods in place, all four rods simultaneously deflect and support the platform on the ground during operation, ensuring platform stability and preventing ground depressions caused by insufficient contact area between the moving wheels and the ground. The foldable design of the support rods also facilitates platform movement. The sliding sleeve, connecting spring, and sliding component work together. When the sliding sleeve moves downwards, it compresses the connecting spring, which in turn moves the sliding component, pulling the first steel wire. This causes the four support rods to deflect and unfold around the shaft. If the ground is uneven and any support rod fails to reach the ground, the sliding sleeve continues to compress the connecting spring, ensuring all four support rods are supported and preventing situations where the support structure is not in contact with the ground.
[0008] Furthermore, a vertically arranged screw shaft is rotatably connected inside the base, and a sliding sleeve is fitted onto the screw shaft and threadedly connected to the screw shaft.
[0009] By using a screw shaft, the rotation of the screw shaft allows the sliding sleeve to move up and down along the screw shaft axis.
[0010] Furthermore, a drive shaft is rotatably connected to the base. One end of the drive shaft is inserted into the base and the other end, which is located outside, is fixedly connected to a handle. The end of the drive shaft inserted into the base is fixedly connected to a drive wheel. A driven wheel is fixedly connected to the screw shaft, and the driven wheel meshes with the drive wheel.
[0011] With the help of the drive shaft, the drive wheel and the driven wheel work together. By turning the handle, the drive shaft can be rotated, which in turn drives the screw shaft to rotate, allowing the sliding sleeve to move up and down, which facilitates the retraction or unfolding of the support rod.
[0012] Furthermore, a ratchet coaxially arranged with the rotating shaft end is fixedly connected to the support rod, and a ratchet tooth for limiting the ratchet is rotatably connected inside the base. The ratchet tooth includes a rotating part and a limiting part. The rotating part is rotatably engaged with the base, and the limiting part limits the ratchet in one direction.
[0013] With the ratchet and ratchet mechanism, when the support rod is extended, the ratchet does not limit the ratchet, allowing the support rod to extend and support the ground. When the support rod is supported on the ground, the ratchet limits the support rod, allowing the support rod to provide support force to the base.
[0014] Furthermore, a return spring is fixedly connected between the ratchet and the base, with both ends of the return spring fixedly connected to the ratchet and the base, respectively.
[0015] The reset spring is designed to limit the ratchet's position under its action.
[0016] Furthermore, an abutment plate located on the upper side of the sliding sleeve is slidably connected inside the base. The abutment plate is used to abut against the abutment retaining ring at the upper end of the sliding sleeve. A third steel wire is fixedly connected to the abutment plate. One end of the third steel wire is fixedly connected to the ratchet tooth for pulling the ratchet tooth. A through hole is provided on the abutment plate for the screw shaft to pass through.
[0017] By using the abutment plate and the third steel wire, when the abutment retaining ring on the sliding sleeve pushes the abutment plate, the abutment plate pulls the third steel wire, which in turn pulls the ratchet, so that the ratchet no longer limits the ratchet.
[0018] Furthermore, a guide post is fixedly connected to the abutment ring at the lower end of the sliding sleeve, and the guide post passes through the sliding member and slides in cooperation with the sliding member.
[0019] Furthermore, a lead screw is rotatably connected to the base, and a sliding block is slidably disposed on the upper end face of the base on the lead screw. The sliding block is threadedly connected to the lead screw. The scissor lifting structure includes two first hinge rods hinged to the base. One end of the first hinge rod is slidably disposed on the lifting platform. Two second hinge rods are also hinged to the sliding block. One end of the second hinge rod is hinged to the lifting platform. The first hinge rods are respectively hinged to the second hinge rods.
[0020] With the scissor-type lifting structure, when the lead screw is rotated, the sliding block moves, and then the lifting platform can move up and down under the action of the first hinge rod and the second hinge rod.
[0021] The beneficial effects of this application are as follows:
[0022] 1. With the support rods in place, when the platform is supported, the four support rods simultaneously deflect and support the ground, ensuring the platform's stability and preventing the ground from sinking due to the small contact area between the moving wheels and the ground. In addition, the support rods are foldable, making it easy to move the platform.
[0023] 2. Through the sliding sleeve, connecting spring, and sliding component, when the sliding sleeve moves downward, it compresses the connecting spring, which in turn drives the sliding component to move, thereby pulling the first steel wire. Under the action of the shaft end, the four support rods deflect around the rotating shaft end and unfold. When the ground is uneven and some support rods fail to support the ground, the sliding sleeve can continue to compress the connecting spring, so that all four support rods can be supported on the ground, avoiding the situation where the bracket is not in contact with the ground.
[0024] 3. With the ratchet and ratchet teeth, when the support rod is extended, the ratchet teeth do not limit the ratchet teeth, allowing the support rod to extend and support the ground. When the support rod is supported on the ground, the ratchet teeth limit the support rod, allowing the support rod to provide support force to the base. Attached Figure Description

[0040] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0041] Reference Figure 1-6An engineering anti-tipping platform includes: a base 100, casters 101, a lifting platform 102, a support rod 103, a sliding sleeve 104, a retaining ring 105, a sliding element 106, a connecting spring 107, a rotating shaft end 108, a first steel wire 109, a second steel wire 110, a screw shaft 111, a drive shaft 112, a drive wheel 113, and a driven wheel 114. The base 100 has casters 101 at its lower end, allowing it to move easily to different construction positions. The lifting platform 102 is located on the upper side of the base 100, enabling lifting operations. A lead screw 115 is rotatably connected to the base 100, and a sliding block 116 is threadedly connected to the lead screw 115, slidingly mounted on the base 100. Two first hinge rods 117 are hinged to the base 100, with one end of each first hinge rod 117 slidably mounted under the lifting platform 102. Two second hinge rods 118 are hinged to the sliding block 116. Each of the two second hinge rods 118 is hinged to one of the two first hinge rods 117 at a midpoint, forming a scissor structure. One end of each of the two second hinge rods 118 is hinged to the lifting platform 102. Rotating the lead screw 115 moves the sliding block 116, causing the lifting platform 102 to rise or fall under the action of the first hinge rods 117 and the second hinge rods 118.
[0042] A drive shaft 112 is rotatably connected to the base 100. A handle is fixedly connected to one end of the drive shaft 112, and the other end of the drive shaft 112 is inserted into the base 100 and fixedly connected to a drive wheel 113. An inner cavity is formed inside the base 100. A vertically arranged screw shaft 111 is rotatably connected inside the base 100. A driven wheel 114 that meshes with the drive wheel 113 is fixedly connected to the screw shaft 111. By rotating the drive shaft 112, the screw shaft 111 is driven to rotate under the action of the drive wheel 113 and the driven wheel 114.
[0043] A sliding sleeve 104 is slidably connected up and down inside the base 100. The sliding sleeve 104 is fitted onto the screw shaft 111 and threadedly connected to the screw shaft. When the screw shaft 111 rotates, it drives the sliding sleeve 104 to move up and down. Abutment rings 105 are fixedly connected to both the upper and lower ends of the sliding sleeve 104. Four sliding members 106 are slidably connected inside the base 100. A connecting spring 107 is provided between the sliding member 106 and the abutment ring 105 fixed at the lower end of the sliding sleeve 104. The connecting spring 107 is fixedly connected to both the abutment ring 105 and the sliding member 106. A guide post is fixedly connected to the abutment ring 105 fixed at the lower end of the sliding sleeve 104. The guide post passes through the sliding member 106 and slides in cooperation with the sliding member 106.
[0044] Four support rods 103 are rotatably mounted on the base 100. Two rotating shafts 108 are fixedly mounted on each support rod 103, and these shafts 108 rotatably engage with the base 100, allowing the four support rods 103 to rotate and unfold around the shafts 108. A first steel wire 109 is fixedly connected to a sliding member 106, wound around one of the rotating shafts 108 and fixedly connected to it. When the sliding member 106 moves downward, it pulls the first steel wire 109, causing the support rods 103 to flip and unfold under the action of the rotating shaft 108. A second steel wire 110 is fixedly connected to the sliding member 106, wound around the other rotating shaft 108 and fixedly connected to it. When the sliding member 106 moves upward, it pulls the second steel wire 110, causing the support rods 103 to retract under the action of the rotating shaft 108. The first steel wire 109 and the second steel wire 110 are arranged in opposite directions. When the sliding member 106 moves downward, it pulls the first steel wire 109 and relaxes the second steel wire 110; when the sliding member 106 moves upward, it pulls the second steel wire 110 and relaxes the first steel wire 109.
[0045] A ratchet 119, coaxially arranged with the rotating shaft end 108, is fixedly connected to the support rod 103. A ratchet 120, which unidirectionally limits the ratchet 119, is rotatably arranged on the base 100. When the support rod 103 is flipped open, the ratchet 120 does not limit the ratchet 119; when the support rod 103 is fully extended, the ratchet 120 limits the ratchet 119, so that the support rod 103 provides a supporting force to the base 100. A return spring 121 is provided between the ratchet 120 and the base 100, with both ends of the return spring 121 fixedly connected to the ratchet 120 and the base 100, respectively. The ratchet 120 includes a rotating part that rotatably engages with the base 100 and a limiting part for limiting the ratchet 119.
[0046] A sliding contact plate 122 is slidably connected within the base 100, located at the upper end of the sliding sleeve 104. The contact plate 122 has a through hole 124 for the screw shaft 111 to pass through. When the sliding sleeve 104 moves upward, the contact retaining ring 105 at the upper end of the sliding sleeve 104 contacts the contact plate 122 and pushes the contact plate 122 to move. A third steel wire 123 is fixedly connected to the contact plate 122, with one end of the third steel wire 123 fixedly connected to the ratchet 120. When the sliding sleeve 104 pushes the contact plate 122, the contact plate 122 pulls the third steel wire 123, thereby causing the ratchet 120 to no longer limit the ratchet 119, facilitating the retraction of the support rod 103.
[0047] Usage instructions or work process:
[0048] 1. The platform is moved to the construction position by the moving wheel 101. The drive shaft 112 is rotated by turning the handle. Under the action of the drive wheel 113 and the driven wheel 114, the screw shaft 111 rotates, which in turn drives the sliding sleeve 104 to move downward. At this time, under the action of the connecting spring 107, the sliding member 106 moves downward, which in turn pulls the first steel wire 109 and releases the second steel wire 110. Under the action of the rotating shaft end 108, the support rod 103 deflects and unfolds, and the support rod supports the ground. When the ground is uneven, when one or more support rods 103 are in contact with the ground, the remaining support rods 103 may not be in contact with the ground. At this time, the drive wheel 113 is rotated again, which causes the abutment ring 105 at the lower end of the sliding sleeve 104 to compress the connecting spring 107, so that the support rods 103 that are not in contact with the ground continue to move and contact the ground. At this time, the ratchet 120 limits the ratchet 119 to ensure stable support and prevent tipping.
[0049] 2. When the support rod 103 needs to be retracted, the drive shaft 112 is rotated in the opposite direction, which in turn drives the screw shaft 111 to reverse, causing the sliding sleeve 104 to move upward. At this time, under the action of the ratchet 120, the support rod 103 cannot deflect and retract, and the sliding part 106 cannot move, which will stretch the connecting spring 107. When the sliding sleeve 104 moves to the upper end of the abutment ring 105 and pushes the abutment plate 122, the abutment plate 122 pulls the third spring, so that the ratchet 120 no longer limits the ratchet 119. At this time, the support rod 103 can be retracted. Under the action of the connecting spring 107, the support rod 103 flips and retracts, making it easy to move. When the support rod 103 needs to be unfolded again, the sliding sleeve 104 will move downward and will no longer push the abutment plate 122. Under the action of the return spring 121, the ratchet 120 can continue to limit the ratchet 119 in one direction.
