Description

Technical Field

[0001] This utility model relates to the field of pavement construction equipment, and more specifically, to a pavement template quick alignment device. Background Technology

[0002] In pavement concrete construction, steel formwork is typically used. During construction, measurements and layout must first be carried out according to the design drawings, and then the formwork is erected vertically on the water-stabilized base layer along the placement line. Commonly used steel formwork specifications are 5m long and 5cm wide, with a height 2cm less than the pavement panel thickness, generally 40cm, and a single piece weighing approximately 250kg. The transportation and elevation adjustment of the pavement formwork require manual labor combined with machinery. To ensure that the formwork elevation and straightness meet design requirements, it is often necessary to manually place wooden blocks under both ends of the formwork to adjust the elevation. However, due to the large weight of the formwork, it is impossible for a single person to operate it independently.

[0003] Traditional tools for lifting formwork consist of a simple device made of horizontal reinforcing bars welded to the end of a steel pipe. Adjusting the formwork elevation requires one person to lift the formwork while another inserts wooden shims. Furthermore, adjacent formwork sections must be adjusted separately, requiring two separate operations, increasing labor intensity and leading to low work efficiency. Moreover, existing adjustment tools are inefficient in actual construction, failing to meet the demands of rapid and efficient construction. Therefore, there is an urgent need for a rapid alignment device for pavement formwork that can solve the above problems. Utility Model Content

Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0020] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0021] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0022] Example 1: As Figures 1-7 As shown, a pavement template quick alignment device includes: a support structure 1, a lever structure 2 movably connected to the support structure 1, the two ends of the lever structure 2 being a lifting end and a pressing end, respectively, the distance between the lifting end of the lever structure 2 and the support structure 1 being less than the distance between the pressing end of the lever structure 2 and the support structure 1; the lifting end of the lever structure 2 is movably connected to a lifting structure 3 for controlling the elevation adjustment of the two pavement templates to be aligned.

[0023] The working principle and technical effects of the above scheme are as follows: In this utility model, a pavement template quick alignment device includes a support structure 1 that provides basic support for the entire device. A lever structure 2 is movably connected to the support structure 1, forming a movable lever system. The two ends of the lever structure 2 are a lifting end and a pressing end, respectively, and the distance between the lifting end and the support structure 1 is smaller than the distance between the pressing end and the support structure 1. This design conforms to the lever principle, so as to generate a large lifting force with a small force. A lifting structure 3 is movably connected to the lifting end of the lever structure 2 and is used to directly control the elevation adjustment of the two pavement templates to be aligned. When the elevation of the pavement template needs to be adjusted, the lower end of lever structure 2 is manually pressed down. According to the lever principle, the lower end moves downward under force. Since lever structure 2 is movably connected to support structure 1, lever structure 2 will rotate around the connection point with support structure 1, thereby causing the lifting end to move upward. The upward movement of the lifting end drives the lifting structure 3, which is movably connected to it, to rise. Lifting structure 3 acts on the two pavement templates to be aligned, thereby realizing the elevation adjustment of the pavement templates. This utility model can achieve rapid elevation adjustment. Through the simple operation of manually pressing down the lower end of lever structure 2, the lifting structure 3 can be raised and the two pavement templates to be aligned can be controlled. Elevation adjustment eliminates the need for tedious adjustments to each of the two formwork panels separately, significantly reducing adjustment time and enabling rapid elevation adjustment of both pavement formwork panels. Utilizing the lever principle, by rationally setting the distance between the lifting and pressing ends of the lever structure 2 and the supporting structure 1, a single operator can generate sufficient lifting force with relatively small effort to easily lift two heavy pavement formwork panels to the same height. This changes the traditional method that required multiple people to lift the formwork, reducing the manpower required. A single person can complete the formwork lifting and elevation adjustment work that previously required multiple people, reducing labor input and saving labor costs. At the same time, the rapid adjustment process avoids the tedious operations and multiple adjustments of the traditional method, improving work efficiency and better meeting the schedule requirements of pavement construction.

[0024] Example 2: Figures 1-7As shown, in a pavement template quick alignment device of this utility model, the lifting structure 3 includes: a transverse connecting rod 301 connected to the lifting end of the lever structure 2; two end rings 302 are fitted opposite each other at both ends of the transverse connecting rod 301; the two end rings 302 are connected to the connecting sections of two right-angle steel bars 303; the lifting sections of the two right-angle steel bars 303 are located away from the supporting structure 1. The length of the lifting section of the right-angle steel bar 303 is less than the length of the connecting section of the right-angle steel bar 303. One or more widening steel bars 304 are welded to both sides of the lifting section of the right-angle steel bar 303.

[0025] The working principle and technical effects of the above scheme are as follows: In this utility model, the lifting structure 3 is a key component for adjusting the elevation of the pavement template. The lifting structure 3 works in conjunction with the lever structure 2. The lever structure 2 acts as a force transmission and amplification mechanism, providing power to the lifting structure 3. When the lower end of the lever structure 2 is manually pressed down, according to the lever principle, the lifting end of the lever structure 2 will move upward, thereby driving the lifting structure 3 connected to it to move upward as a whole.

[0026] In the lifting structure 3, the transverse connecting rod 301 is connected to the lifting end of the lever structure 2, serving to transmit the lifting force of the lever structure 2. When the lifting end of the lever structure 2 moves upward, the transverse connecting rod 301 also moves upward, transmitting this movement to subsequent components. Two end rings 302 are fitted opposite each other at both ends of the transverse connecting rod 301. The two end rings 302 and the transverse connecting rod 301 can move relative to each other, allowing the end rings 302 to adapt to certain positional changes on the transverse connecting rod 301. The end rings 302 mainly serve to connect the transverse connecting rod 301 and the right-angle steel bar 303, transmitting the upward movement of the transverse connecting rod 301 to the right-angle steel bar 303. The right-angle steel bar 303 is connected to two end rings 302 through its connecting section. When the end rings 302 move upward with the transverse connecting rod 301, the right-angle steel bar 303 is also driven upward. The lifting section of the right-angle steel bar 303 is set away from the supporting structure 1, so that the lifting section can directly act on the pavement formwork to be adjusted. Since the length of the lifting section of the right-angle steel bar 303 is less than the length of the connecting section of the right-angle steel bar 303, it can better adapt to the position and height of the formwork during the lifting process, and lift the formwork at a suitable angle and position. One or more widening steel bars 304 are welded to both sides of the lifting section of the right-angle steel bar 303. The widening steel bars 304 increase the contact area between the lifting section and the pavement formwork. When the right-angle steel bar 303 lifts the formwork, the widened steel bar 304 can more stably support the formwork, preventing the formwork from tilting or slipping during the lifting process. This ensures the formwork rises smoothly and avoids the risk of tilting or slipping due to uneven stress, thus guaranteeing construction safety. It also allows for more precise control of the formwork elevation and improves the accuracy of formwork alignment.

[0027] Example 3: As Figures 1-7 As shown, in one technical solution of the pavement template quick alignment device of this utility model, the transverse connecting rod 301 is welded to the lifting end of the lever structure 2, and four constraint protrusions are welded on the transverse connecting rod 301, with each end ring 302 fitting between two constraint protrusions.

[0028] The working principle and technical effects of the above scheme are as follows: In this scheme, the transverse connecting rod 301 is welded to the lifting end of the lever structure 2, and the two have good stability. Four constraint protrusions are welded on the transverse connecting rod 301, and each end ring 302 is fitted between two constraint protrusions, so that the end ring 302 will not detach from the transverse connecting rod 301. In this scheme, the end ring 302 can rotate relative to the transverse connecting rod 301, so that the right angle steel bar 303 can move adaptively when lifting the pavement template.

[0029] Example 4: Figures 1-7 As shown, in another technical solution of the pavement template quick alignment device of this utility model, the middle part of the transverse connecting rod 301 is rotatably connected to the transverse through hole of the lifting end of the lever structure 2. Multiple locking slots are respectively provided at both ends of the transverse connecting rod 301 along its axial direction. The end ring 302 is rotatably fitted onto the transverse connecting rod 301, and a locking stud 4 is threaded onto the end ring 302. The locking stud 4 is inserted into a locking slot. The lifting end of the lever structure 2 is threadedly connected to a limiting stud 5, and one end of the limiting stud 5 is inserted into the annular groove in the middle of the transverse connecting rod 301 within the lever structure 2.

[0030] The working principle and technical effects of the above scheme are as follows: In this design, the transverse connecting rod 301 is rotatably connected in the middle to the transverse through hole at the lifting end of the lever structure 2, allowing relative rotation between the two. This enables the right-angle steel bar 303 to adapt to the lifting of the pavement formwork. Multiple locking slots are provided at both ends of the transverse connecting rod 301 along its axial direction. An end ring 302 is rotatably fitted onto the transverse connecting rod 301, and a locking stud 4 is threaded onto the end ring 302. The locking stud 4 is inserted into a locking slot, allowing the end ring 302 and the transverse connecting rod 301 to... The relative positions of the connecting rods 301 are fixed and cannot be rotated. This structure allows for adjustable spacing between the two right-angled steel bars 303. By adjusting the locking stud 4 to disengage from the locking slot, the two end rings 302 can slide on the transverse connecting rod 301, thus controlling the adjustment of the positions of the two right-angled steel bars 303. After adjustment, the position of the right-angled steel bars 303 can be fixed by inserting the locking stud 4 into the corresponding locking slot. Adjusting the positions of the two right-angled steel bars 303 allows for alignment with different pavement templates. The lifting end of the lever structure 2 is threadedly connected to a limiting stud 5. One end of the limiting stud 5 is inserted into the annular groove in the middle of the transverse connecting rod 301, preventing lateral displacement of the transverse connecting rod 301 and facilitating disassembly. Disassembly is achieved by controlling the limiting stud 5 to disengage from the annular groove in the middle of the transverse connecting rod 301, making operation very convenient and facilitating the replacement of damaged parts.

[0031] Example 5: Figures 1-7 As shown, in a pavement template quick alignment device of this utility model, the support structure 1 includes: an H-shaped bracket 101 and two sleeves 102 welded to the top ends of the H-shaped bracket 101; the lever structure 2 includes: a lever body 201 and sleeve posts 202 vertically welded to the lever body 201, with the two ends of the sleeve posts 202 rotatably fitted within the two sleeves 102. Two anti-tipping supports 103 are fixedly connected to the bottom ends of the H-shaped bracket 101.

[0032] The working principle and technical effects of the above scheme are as follows: The H-shaped bracket 101, as the main body of the support structure 1, provides a stable support foundation. Placed on the construction ground, the H-shaped bracket 101 bears the pressure and force generated by the lever structure 2 and the lifting structure 3 during operation. Two sleeves 102 welded to the top ends of the H-shaped bracket 101 connect to the lever structure 2. The sleeves 102 provide support points and space for the rotation of the lever structure 2, allowing it to rotate around the sleeves 102, thus achieving force transmission and conversion. The lever body 201 is the core component of the lever structure 2. When downward pressure is applied to the lower end of the lever body 201 manually, because the lever body 201 is rotatably connected to the support structure 1 through the sleeve 202 and the sleeves 102, the lever body 201 will rotate around the sleeves 102, thereby... The lifting end of the lever body 201 moves upward; the sleeve post 202, which is vertically welded to the lever body 201, has its two ends rotatably fitted within the two sleeves 102, allowing the lever body 201 to rotate flexibly under the support of the sleeves 102. This transmits the force manually applied to the lower end of the lever body 201 to the lifting end, thereby driving the lifting structure 3 to move and lifting the pavement template; the two anti-tipping pillars 103, which are fixed to the bottom ends of the support structure 1, respectively, enhance the stability of the device. During the operation of the device, especially when the lever structure 2 rotates and the template is lifted, a certain lateral force and sway will be generated. The anti-tipping pillars 103 can increase the contact area and stability between the support structure 1 and the ground, preventing the device from tipping over due to uneven force, and ensuring the safety and reliability of the entire operation process.

[0033] Example 6: As Figures 1-7 As shown, in a pavement template quick alignment device of this utility model, the lower pressing end of the lever body 201 is provided with an internal thread groove, the internal thread groove is internally threaded to the extension pressure rod 6, and the extension pressure rod 6 is glued to and fixed with a rubber anti-slip sleeve.

[0034] The working principle and technical effects of the above scheme are as follows: The lever body 201 has an internal threaded groove at its lower end, which is threadedly connected to the extension rod 6. By increasing the length of the rod, the operating arm of the lever is extended. According to the lever principle, with the resistance and resistance arm remaining constant, the longer the lever arm, the less force is required. This allows the operator to press down the lever with less force, reducing labor intensity and making operation easier. For example, when lifting heavy pavement formwork, the extension rod 6 allows a single person to easily complete the lifting operation. The extension rod 6 is threadedly connected to the lever body 201, facilitating disassembly and installation. In different construction scenarios, when a larger operating arm is required, the extension rod 6 can be extended outside the lever body 201, and the extension length can be adjusted according to actual needs. When space is limited or the extension rod is not needed, the extension rod 6 can be retracted into the lever body 201. In addition, a rubber anti-slip sleeve is glued to the extension rod 6, which has a large friction force. When the operator presses down the extension lever 6, the anti-slip sleeve effectively prevents the hand from slipping between the hand and the lever, avoiding operational errors caused by hand slippage, thereby reducing potential safety accidents caused by operational errors and ensuring the personal safety of the operator. The rubber anti-slip sleeve also provides a more comfortable grip, allowing the operator to hold the extension lever 6 more stably during operation, better control the downward pressure and direction, and further improve the safety and accuracy of the operation.
