Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and more specifically, to an automatic formwork lifting device. Background Technology

[0002] Currently, the most common method for formwork support frames in concrete slab construction is to erect a full-span support frame, which is composed of multiple support components (based on the base, columns, upper beams, lower beams, etc.) and connectors to form an integral structure.

[0003] However, this method not only involves a large workload and a long formwork time, but also poses risks of working at height. In addition, it requires the addition of a large number of horizontal braces, scissor braces and sweeping braces to reinforce and fix the support, resulting in the dedicated passage becoming narrow and congested, and obstructing passage. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an automatic formwork lifting device to solve the technical problems in the prior art where the use of full-span support frames for formwork support leads to increased labor load and operational risks.

[0005] To solve the above problems, this utility model provides an automatic template lifting device for supporting a fixed template, comprising:

[0006] At least two automatic lifting components, each of the automatic lifting components including a vertically arranged support tube, a lifting rod located inside the support tube, an adjustable support plate connected to both ends of the support tube, and a drive motor drivenly connected to the lifting rod, the drive motor being adapted to drive the lifting rod to rotate and raise the height;

[0007] The steel beam track is horizontally installed at the top of the automatic lifting assembly, and the shaping template is located between the two steel beam tracks.

[0008] Preferably, the support tube includes a bottom support tube, a top support tube inserted at the top of the bottom support tube, and a locking member, wherein the locking member is used to fix the bottom support tube and the top support tube.

[0009] Preferably, the lifting rod includes a screw rod located inside the bottom support tube and a lead screw located inside the top support tube, and the bottom of the lead screw is threadedly connected to the top of the screw rod. The bottom end of the screw rod is connected to the output shaft of the drive motor through a worm gear transmission to drive the screw rod to rotate. The rotation of the screw rod further drives the lead screw rod to move up and down relative to the screw rod.

[0010] Preferably, the adjustable support plate includes a base fixedly installed at the bottom end of the bottom support tube and a top seat fixedly installed at the top end of the lead screw.

[0011] Preferably, the base includes a base box fixedly connected to the bottom end of the bottom support tube and a plurality of adjustable base supports evenly supported at the bottom of the base box, and the drive motor is installed in the base box.

[0012] Preferably, the top seat includes a sealing plate fixedly connected to the top of the lead screw and an adjustable top support mounted on the upper surface of the sealing plate, wherein the side of the adjustable top support away from the sealing plate is adapted to be supported on the steel beam track.

[0013] Preferably, it also includes a control cabinet located on one side of the automatic lifting assembly, the control cabinet being electrically connected to the drive motor.

[0014] Preferably, the control cabinet includes control buttons and cables installed on the control cabinet body, one end of the cable being electrically connected to the control cabinet and the other end being electrically connected to the drive motor.

[0015] Preferably, the locking element is a safety pin.

[0016] Preferably, the threaded connection distance between the screw and the lead screw is greater than the lifting distance of the steel beam track.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] The automatic template lifting device of this application includes at least two automatic lifting components and steel beam tracks. A support pipe is vertically installed in a predetermined position to ensure its verticality and stability. Then, a lifting rod is placed inside the support pipe, ensuring it can rotate freely and move up and down. A drive motor is connected to the lifting rod to ensure sufficient power to rotate and lift it to the desired height. Adjustable support plates are installed at both ends of the support pipe to better support the steel beam tracks and the template. The steel beam tracks are then horizontally installed on top of the automatic lifting components, maintaining a horizontal position to ensure the flatness and stability of the template after installation. By using multiple automatic lifting components to support the steel beam tracks, the template is finally installed between the two steel beam tracks, ensuring a tight fit between the template and the tracks, and allowing for smooth movement or fixation on the tracks. When it is necessary to raise the template, the drive motor is activated, causing the lifting rod to rotate. The lifting rod gradually rises during rotation, thereby pushing the support pipe upwards. Because the adjustable support plates are connected to both ends of the support pipe, as the support pipe rises, the adjustable support plates rise synchronously, driving the steel beam track and the shaped formwork together to the predetermined height. Thus, the lifting rod is rotated and raised by a drive motor, achieving automatic lifting of the shaped formwork. Compared with traditional manual or mechanical lifting methods, this device can complete the formwork lifting work faster and more efficiently, greatly saving labor and time costs and improving construction efficiency.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The terms “vertical,” “horizontal,” “left,” “right,” and similar expressions used in this document are for illustrative purposes only and do not represent the only possible implementation.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] Please see Figure 1-4 As shown, this embodiment of the utility model provides an automatic template lifting device, which includes at least two automatic lifting components 1 and a steel beam track 2, wherein:

[0037] Each automatic lifting assembly 1 includes a support tube 11, a lifting rod 12, an adjustable support plate 13, and a drive motor 14. The support tube 11 is vertically arranged, the lifting rod 12 is located inside the support tube 11, the adjustable support plate 13 is connected to both ends of the support tube 11, and the drive motor 14 is driven to drive the lifting rod 12 to rotate and raise the height.

[0038] The steel beam track 2 is horizontally installed at the top of the automatic lifting component 1, and the fixed template 4 is placed between the two steel beam tracks 2.

[0039] During installation, the support pipe 11 is first vertically installed in the predetermined position to ensure its verticality and stability. As the core component of the entire automatic jacking assembly 1, the support pipe 11 needs to have sufficient strength and rigidity to withstand various loads generated during the jacking process. Then, the jacking rod 12 is placed inside the support pipe 11, ensuring it can rotate freely and move up and down. The drive motor 14 is connected to the jacking rod 12, typically via a coupling or other transmission device. The selection of the drive motor 14 should be determined based on the torque and speed requirements of the jacking, ensuring it can provide sufficient power to drive the jacking rod 12 to rotate and raise the height. Adjustable support plates 13 are installed at both ends of the support pipe 11. The adjustable support plates 13 are connected to the support pipe 11 by bolts or other connectors, and their position and angle can be adjusted according to actual needs to better support the steel beam track 2 and the shaped template 4. Next, the steel beam track 2 is horizontally installed at the top of the automatic jacking assembly 1, i.e., on the upper adjustable support plate 13 of the support pipe 11. The steel beam track 2 needs to be kept horizontal to ensure the flatness and stability of the prefabricated template 4 after installation. Multiple automatic lifting components 1 are typically used to support the steel beam track 2. The length and specifications of the steel beam track 2 should be determined based on the size and weight of the prefabricated template 4. Finally, the prefabricated template 4 is installed between the two steel beam tracks 2, ensuring a tight fit between the template and the tracks, and allowing for smooth movement or fixation on the tracks. The installation method of the prefabricated template 4 can be adjusted according to specific construction requirements, such as fixing it to the steel beam track 2 with fasteners or allowing it to slide on the tracks.

[0040] When it is necessary to raise the height of the template 4, the drive motor 14 is started. The drive motor 14 drives the lifting rod 12 to rotate. The lifting rod 12 gradually rises during the rotation, thereby pushing the support tube 11 to move upward. Since the adjustable support plate 13 is connected to both ends of the support tube 11, as the support tube 11 rises, the adjustable support plate 13 rises synchronously and drives the steel beam track 2 and the template 4 to rise together to the predetermined height.

[0041] During the lifting process, the rising height of the lifting rod 12 can be precisely adjusted by controlling the rotation speed and angle of the drive motor 14, thereby achieving precise control over the height of the shaping template 4. When the shaping template 4 rises to the predetermined position, the drive motor 14 stops working, and the lifting rod 12 maintains its current position within the support tube 11, stably supporting the shaping template 4 at the required height.

[0042] Thus, by driving the lifting rod 12 to rotate and raise the height via the drive motor 14, the automatic lifting of the formwork 4 is achieved. Compared with traditional manual or mechanical lifting methods, this device can complete the lifting of the formwork more quickly and efficiently, greatly saving manpower and time costs and improving construction efficiency.

[0043] Specifically, please refer to Figure 1 As shown, the support tube 11 includes a bottom support tube 111, a top support tube 112 and a locking member. The top support tube 112 is inserted into the top of the bottom support tube 111, and the locking member is used to fix the bottom support tube 111 and the top support tube 112.

[0044] Specifically, the top support tube 112 is inserted from above into the top of the bottom support tube 111. The size and shape of the top support tube 112 should match the top insertion hole of the bottom support tube 111 to ensure a smooth insertion process and a tight connection.

[0045] Then, use locking devices to secure the bottom support tube 111 and the top support tube 112 together. The locking devices can be bolts, nuts, clamps, etc. By tightening the locking devices, the bottom support tube 111 and the top support tube 112 are tightly connected, forming a stable whole. The installation position and tightening force of the locking devices need to be in accordance with design requirements to ensure the reliability of the connection.

[0046] Specifically, please refer to Figure 1 , 2 As shown, the lifting rod 12 includes a screw 121 and a lead screw 122. The screw 121 is located inside the bottom support tube 111, and the lead screw 122 is located inside the top support tube 112. The bottom of the lead screw 122 is threadedly connected to the top of the screw 121. The bottom end of the screw 121 is connected to the output shaft of the drive motor 14 through a worm gear transmission to drive the screw 121 to rotate. The rotation of the screw 121 further drives the lead screw 122 to move up and down relative to the screw 121.

[0047] In this embodiment, the screw 121 is installed inside the bottom support tube 111, ensuring coaxiality between the screw 121 and the bottom support tube 111. The bottom end of the screw 121 is connected to the output shaft of the drive motor 14 via a worm gear transmission mechanism. During installation, it is necessary to ensure proper meshing of the worm gear transmission mechanism to achieve effective drive of the screw 121 by the drive motor 14. The lead screw 122 is installed inside the top support tube 112, ensuring coaxiality between the lead screw 122 and the top support tube 112. The bottom of the lead screw 122 is threadedly connected to the top of the screw 121. During connection, it is necessary to ensure proper thread fit to achieve stable connection and relative movement between the lead screw 122 and the screw 121.

[0048] After the drive motor 14 starts, it drives the screw 121 to rotate through the worm gear transmission mechanism. The rotation of the screw 121 is transmitted to the lead screw 122 through a threaded connection, causing the lead screw 122 to move up and down relative to the screw 121. The upward movement of the lead screw 122 pushes the top support tube 112 upward, thereby driving the steel beam track 2 and the shaped template 4 to rise through the adjustable support plate 13.

[0049] When it is necessary to lower the height of the shaping template 4, the drive motor 14 rotates in the opposite direction, causing the screw 121 to rotate in the opposite direction. The reverse rotation of the screw 121 causes the lead screw 122 to descend relatively, thereby driving the top support tube 112 and the shaping template 4 to descend smoothly to the required position.

[0050] Specifically, please refer to Figure 1 , 2 As shown, the adjustable support plate 13 includes a base 131 and a top plate 132. The base 131 is fixedly installed at the bottom end of the bottom support tube 111. The base 131 is usually firmly connected to the bottom support tube 111 by welding, bolt connection or other means to ensure its stability during use.

[0051] The top seat 132 is fixedly installed on the top of the lead screw 122. The top seat 132 is also fixed to the lead screw 122 by a reliable connection method (such as threaded connection, key connection, etc.) to ensure that the top seat 132 can stably transmit force during the lifting process.

[0052] When the lifting rod 12 drives the lead screw 122 to rotate and rise, the top seat 132 rises accordingly. The top seat 132 contacts the steel beam track 2 and lifts it up, thereby driving the shaped template 4 to rise. The base 131 plays a stabilizing role at the bottom end of the bottom support tube 111, ensuring the stability of the entire lifting system.

[0053] By controlling the rotation of the drive motor 14, the rising or falling height of the lead screw 122 can be adjusted, thereby achieving precise control of the height of the top seat 132. The height change of the top seat 132 is directly transmitted to the steel beam track 2 and the shaping template 4, completing the adjustment of the template height.

[0054] Specifically, please refer to Figure 2 As shown, the base 131 includes a base housing 1311 and adjustable base supports 1312. The base housing 1311 is fixedly connected to the bottom end of the bottom support tube 111. Several adjustable base supports 1312 are evenly supported on the bottom of the base housing 1311. The adjustable base supports 1312 are installed on the base housing 1311 by threads or other adjustable structures to ensure that each adjustable base support 1312 can be independently adjusted in height. A drive motor 14 is installed inside the base housing 1311. The installation of the drive motor 14 requires that its output shaft be correctly connected to the worm gear transmission mechanism to ensure that it can effectively drive the screw 121 to rotate.

[0055] When the drive motor 14 starts, it drives the screw 121 to rotate through the worm gear transmission mechanism, which in turn causes the lead screw 122 to rise, pushing the top seat 132 and the shaping template 4 to rise. During the lifting process, the adjustable base 1312 automatically or manually adjusts its height according to the flatness of the ground to ensure that the base box 1311 remains horizontal and stable.

[0056] Specifically, please refer to Figure 2 As shown, the top support 132 includes a sealing plate 1321 and an adjustable top support 1322. The sealing plate 1321 is fixedly connected to the top of the lead screw 122. The sealing plate 1321 is typically connected to the lead screw 122 by reliable methods such as welding or bolting to ensure stable force transmission during the lifting process. The adjustable top support 1322 is installed on the upper surface of the sealing plate 1321, and the side of the adjustable top support 1322 away from the sealing plate 1321 is suitable for support on the steel beam track 2. The adjustable top support 1322 is installed on the sealing plate 1321 by threads or other adjustable structures to ensure that its height can be adjusted as needed.

[0057] As the lead screw 122 rotates and rises, the sealing plate 1321 rises accordingly, and the adjustable top support 1322 also rises synchronously. The top of the adjustable top support 1322 contacts the steel beam track 2 and lifts it up, thereby driving the shaped template 4 to rise. By adjusting the height of the adjustable top support 1322, it can be ensured that the steel beam track 2 remains horizontal and stable.

[0058] Specifically, please refer to Figure 1 As shown, the automatic template lifting device also includes a control cabinet 3 located on one side of the automatic lifting component 1, and the control cabinet 3 is electrically connected to the drive motor 14.

[0059] After power is connected, the operator performs system initialization settings through the interface of control cabinet 3, including setting parameters for each drive motor 14, setting limit switches, and preset lifting speed and height. Control cabinet 3 typically has a human-machine interface (such as a touch screen or a combination of buttons / displays) for easy operation.

[0060] Specifically, please refer to Figure 1 As shown, the control cabinet 3 includes a control button 31 and a cable 32. The control button 31 is installed on the control cabinet body. One end of the cable 32 is electrically connected to the control cabinet 3, and the other end is electrically connected to the drive motor 14.

[0061] During construction, the operator sends commands to the drive motor 14 by pressing control button 31. For example, pressing the "Up" button causes the drive motor 14 to rotate forward, raising the lifting rod 12; pressing the "Down" button causes the drive motor 14 to rotate in reverse, lowering the lifting rod 12. Control button 31 provides an intuitive and convenient operating method, allowing the operator to precisely control the operation of the lifting device.

[0062] Control cabinet 3 sends control signals and power to drive motor 14 via cable 32. According to the instructions of control button 31, the control circuit inside control cabinet 3 adjusts parameters such as voltage, current and frequency of drive motor 14 to control motor speed and torque, thereby precisely controlling the movement speed and position of lifting rod 12.

[0063] Specifically, please refer to Figure 1 As shown, the locking element is a safety pin 113.

[0064] Pre-machine corresponding pin holes on the bottom support tube 111 and the top support tube 112 to ensure the position and size accuracy of the pin holes. After the top support tube 112 is inserted into the bottom support tube 111 and adjusted to a suitable height, align the pin holes on the top support tube 112 with the pin holes on the bottom support tube 111.

[0065] Then insert the safety pin 113 into the aligned pin hole, ensuring that the safety pin 113 completely passes through the pin holes of the top support tube 112 and the bottom support tube 111, and protrudes sufficiently for fixation. The insertion of the safety pin 113 should be smooth; if there is resistance, the position of the pin hole or the size of the safety pin 113 can be adjusted appropriately.

[0066] Specifically, in the specific embodiment of this utility model, the threaded connection distance between the screw 121 and the lead screw 122 is greater than the lifting distance of the steel beam track 2.

[0067] Based on the maximum lifting distance requirement of the automatic template lifting device, determine the thread specifications of screw 121 and lead screw 122, and ensure that the thread connection distance between screw 121 and lead screw 122 is greater than the maximum lifting distance of steel beam track 2, so as to meet various lifting needs that may occur during construction.

[0068] Although the present invention is disclosed above, the scope of protection of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the scope of protection of the present invention.
