Description

Technical Field

[0001] This utility model relates to the field of rainwater box culvert construction technology, specifically to an integral lifting sliding box culvert support system. Background Technology

[0002] Currently, the formwork support system used for stormwater box culverts at construction sites often requires a relatively dense arrangement of support poles to meet load requirements, resulting in small spacing between poles and hindering the installation and dismantling of formwork by workers. Furthermore, the existing construction method necessitates repeated assembly and disassembly of the formwork support system when moving to the next section after completion of one section. This not only increases the labor intensity of workers but also makes the operation cumbersome and affects construction efficiency. Therefore, it is necessary to propose a new box culvert support system to solve the aforementioned technical problems. Utility Model Content

The driver sliding base is fixedly mounted on the bottom of the double-crank drive device driver, and the driver base pulleys are mounted on both sides of the bottom of the driver sliding base.

[0006] Furthermore, the track sliding gear lifting pole base includes a supporting pole screw, a large spur bevel gear, a small spur bevel gear, a gear drive shaft support, a large spur bevel gear support, and pole base pulleys. The supporting pole screw passes through the central hole of the large spur bevel gear and is connected to the large spur bevel gear via threads.

After being engaged in the sliding base limiter groove, they limit and fix the pole base of the track sliding gear. The limiter control wrench is installed at the end of the limiter transmission rod and is used to control the working state of the limiter clips.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention, through the installation of a double-crank drive device, a track-sliding gear lifting pole base, a channel steel slide rail, and a pole sliding base limiter, not only enables the overall lifting and height adjustment of the formwork support system, but also allows for the overall sliding of the formwork support system.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0014] Reference Figures 1 to 7 This embodiment provides an integrated lifting sliding box culvert support system, including a double-crank drive device 1, a track sliding gear lifting pole base 2, a channel steel slide rail 3, a pole sliding base limiter 4, and a template support frame 5. The track sliding gear lifting pole base 2 is installed at the bottom of each pole of the template support frame 5. The channel steel slide rail 3 has several rows along the direction of the template support frame 5. Each row of channel steel slide rail 3 is arranged at the bottom of the track sliding gear lifting pole base 2. A double-crank drive device 1 is installed at the end of each row of channel steel slide rail 3. The double-crank drive device 1 is connected to the track sliding gear lifting pole base 2 in the same row and can drive the track sliding gear lifting pole base 2 to work, thereby raising or lowering the template support frame 5. A pole sliding base limiter 4 is installed on one side of each row of channel steel slide rail 3 to limit the track sliding gear lifting pole base 2 and thus fix the template support frame 5.

[0015] In this embodiment, the double-crank drive device 1 includes a double-crank drive device driver 1.1, a driver outer disk 1.2, a double-crank drive transmission rod 1.3, a spur bevel gear pinion outer disk 1.4, a driver sliding base 1.5, and a driver base pulley 1.6. The driver outer disk 1.2 is mounted on the double-crank drive device driver 1.1 and can rotate. One end of the double-crank drive transmission rod 1.3 is hinged to the driver outer disk 1.2, and the other end is hinged to the spur bevel gear pinion outer disk 1.4. The spur bevel gear pinion outer disk 1.4 and the spur bevel gear pinion 2.3 of the track sliding gear lifting pole base 2 are fixed together by a gear transmission shaft. The driver sliding base 1.5 is fixedly mounted on the bottom of the double-crank drive device driver 1.1, and the driver base pulley 1.6 is mounted on both sides of the bottom of the driver sliding base 1.5. During operation, the double-crank drive device driver 1.1 is rotated, which in turn drives the outer disk 1.2 of the driver to rotate. At the same time, the outer disk 1.2 of the driver drives all the outer disks 1.4 of the spur bevel gears and pinions to rotate synchronously through the double-crank drive transmission rod 1.3.

[0016] In this embodiment, the track sliding gear lifting pole base 2 includes a support pole screw 2.1, a large spur bevel gear 2.2, a small spur bevel gear 2.3, a gear drive shaft support 2.4, a large spur bevel gear support 2.5, and pole base pulleys 2.6. The support pole screw 2.1 passes through the center hole of the large spur bevel gear 2.2 and is connected to the large spur bevel gear 2.2 by threads. The large spur bevel gear 2.2 is mounted on the large spur bevel gear support 2.5 by bearings. The gear drive shaft support 2.4 is mounted on the large spur bevel gear support 2.5. The small spur bevel gear 2.3 is mounted on the gear drive shaft support 2.4 by a gear drive shaft and meshes with the large spur bevel gear 2.2. The gear drive shaft is assembled and connected to the outer disk 1.4 of the small spur bevel gear. The pole base pulleys 2.6 are mounted on both sides of the bottom of the large spur bevel gear support 2.5. During operation, the outer disk 1.4 of the spur bevel gear pinion rotates, which drives the spur bevel gear pinion 2.3 to rotate synchronously through the gear transmission shaft. The rotation of the spur bevel gear pinion 2.3 drives the spur bevel gear large gear 2.2 to rotate, thereby causing the support column screw 2.1 to be raised or lowered. As the support column screw 2.1 is raised or lowered, the template support frame 5 is raised or lowered.

[0017] In this embodiment, the channel steel slide rail 3 includes a channel steel slide rail body 3.1, and sliding base limiting grooves 3.2 are respectively provided on both sides of the channel steel slide rail body 3.1; a base pulley guide belt 3.3 is provided inside the channel steel slide rail body 3.1.

[0018] In this embodiment, the pole sliding base limiter 4 includes a limiter transmission rod 4.1, a limiter clip 4.2, a limiter control wrench 4.3, and a limiter support 4.4. The limiter transmission rod 4.1 is installed on the limiter support 4.4, and the limiter clips 4.2 are installed at intervals on the limiter transmission rod 4.1, with two clips forming a group. After being engaged in the sliding base limiter groove 3.2, they limit and fix the pole base 2 of the track sliding gear. The limiter control wrench 4.3 is installed at the end of the limiter transmission rod 4.1 and is used to control the working state of the limiter clips 4.2.

[0019] The working process of this embodiment: After the double crank drive device 1 and the track sliding gear lifting pole base 2 slide to the preset position, the limit control wrench 4.3 is used to control the limit strip 4.2 to engage with the sliding base limit groove 3.2, thereby restricting the sliding of the double crank drive device 1 and the track sliding gear lifting pole base 2.

[0020] When the stormwater culvert is being supported by formwork, the double-crank drive device 1 and the track sliding gear lifting pole base 2 are controlled to raise the formwork support frame 5 to the design elevation. After the concrete is poured and the conditions for demolding are met, the double-crank drive device 1 and the track sliding gear lifting pole base 2 are controlled to lower the formwork support frame 5. Then, a channel steel slide rail 3 and a pole sliding base limiter 4 are laid in front of the formwork support frame 5 to slide the formwork support frame 5 as a whole to the next construction section for construction operations, which greatly improves the convenience and efficiency of construction.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
