Description

Technical Field

[0001] This utility model relates to the field of construction equipment, specifically an adjustable movable template trolley for use in confined spaces. Background Technology

[0002] Currently, in construction projects, the formwork construction of narrow spaces such as gaps and gullies is mostly carried out by manually erecting and assembling formwork. However, the working surface in such spaces is narrow, and workers cannot enter the interior to operate, resulting in low installation efficiency and poor formwork positioning accuracy. Existing formwork trolleys are mostly large track-mounted equipment, which are bulky and consume a lot of steel, making them unsuitable for passage and operation in narrow spaces. In addition, the angle of the top formwork is fixed, making it difficult to match the top shape of the ditch with different slopes. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides an adjustable movable template trolley for confined spaces, which solves the problems mentioned in the background.

[0004] This utility model provides the following technical solution: an adjustable movable template trolley for confined spaces, comprising a template trolley body, the template trolley body including: a trolley support and a diagonal bracing mechanism, the diagonal bracing mechanism including: a support truss, a rotating shaft, and a height adjusting screw, the upper end of the height adjusting screw being fitted with a template, the end of the rotating shaft being fitted with an adjusting handwheel, a ratchet gear being fitted on one side of the adjusting handwheel on the rotating shaft, and movable bearings being fitted inside the rotating shaft and the trolley support.

[0005] As a further improvement of this utility model: a bottom bracket is installed on the lower outer side of the trolley bracket, and universal rollers are installed on the lower surface of the bottom bracket.

[0006] As a further improvement of this utility model: the lower end of the trolley support is provided with a storage groove, the inside of the storage groove is provided with a bottom bracket, and the inside of the storage groove is provided with a limit pin.

[0007] As a further embodiment of this utility model: the rotating shaft is rotatably connected to the trolley support through the movable bearing, and a limit pawl is installed on the side surface of the trolley support located on one side of the ratchet gear.

[0008] As a further improvement of this utility model: the limiting pin is movably connected to the trolley bracket, and a movable shaft is installed between the bottom bracket and the trolley bracket.

[0009] As a further embodiment of this utility model: the bottom bracket is fixedly connected to the trolley bracket, and the universal roller is fixedly connected to the bottom bracket by bolts.

[0010] As a further improvement of this utility model, a limiting collar is installed at the upper end of the height adjusting screw on the lower surface of the template.

[0011] As a further improvement of this utility model: a threaded sleeve is installed on the outer side of the lower end of the height adjusting screw inside the support truss.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By controlling the overall rotation of the handwheel, the rotating shaft rotates inside the trolley support via the movable bearing. Therefore, the rotating shaft drives the diagonal bracing mechanism to swing on both sides of the trolley support, controlling the tilting and rotation of the two diagonal bracing mechanisms on the outside of the trolley support to support surfaces with different tilt angles.

[0013] By rotating the height adjustment screw below the template inside the threaded sleeve, the limiting collar at the end of the height adjustment screw below the template rotates, thus controlling the distance between the template and the trolley bracket to form a herringbone shape that fits the top of the trench.

[0016] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-5 As shown, this embodiment provides an adjustable movable template trolley for confined spaces, including a template trolley body 1. The template trolley body 1 is constructed entirely of welded steel. The template trolley body 1 includes: a trolley support 2 and a diagonal bracing mechanism 4. The diagonal bracing mechanism 4 includes: a support truss 401, a rotating shaft 402, and a height adjusting screw 405. A template 3 is mounted on the upper end of the height adjusting screw 405. The template 3 is made entirely of wood, and the template 3 and the diagonal bracing mechanism 4 can be installed and disassembled. A limit collar is installed on the lower surface of the template 3 at the upper end of the height adjusting screw 405, and a threaded sleeve is installed on the outer side of the lower end of the height adjusting screw 405 inside the support truss 401. When the height adjusting screw 405 and the limit collar are rotated, then... The height adjustment screw 405 can rotate freely with the threaded sleeve, thus allowing the outer side of the template 3 to be pushed to adjust the distance between it and the diagonal bracing mechanism 4, facilitating support adjustment. An adjustment handwheel 5 is installed at the end of the rotating shaft 402, and a ratchet 404 is installed on one side of the adjustment handwheel 5 on the rotating shaft 402. A movable bearing 403 is installed inside the rotating shaft 402 and the trolley support 2, and the rotating shaft 402 is rotatably connected to the trolley support 2 through the movable bearing 403. A limit pawl is installed on the side surface of the trolley support 2 on one side of the ratchet 404. When the rotating shaft 402 drives the diagonal bracing mechanism 4 to adjust the orientation angle at both ends of the trolley support 2, the limit pawl and the one-way limit of the ratchet 404 ensure stability during support.

[0018] like Figure 2-3 As shown, in this embodiment, a bottom bracket 6 is installed on the outer side of the lower end of the trolley support 2. The bottom bracket 6 is fixedly connected to the trolley support 2. A universal roller 601 is installed on the lower surface of the bottom bracket 6. The universal roller 601 is fixedly connected to the bottom bracket 6 by bolts. A storage groove 201 is opened at the lower end of the trolley support 2. A bottom support 7 is provided inside the storage groove 201. A limit pin 202 is provided inside the storage groove 201. The limit pin 202 is movably connected to the trolley support 2. A movable shaft is installed between the bottom support 7 and the trolley support 2.

[0019] The working principle of this utility model is as follows: When in use, the template trolley body 1 is moved to the required processing position by using the universal rollers 601. After the position adjustment is completed, the limit pin 202 is pulled out of the storage slot 201, and the bottom bracket 7 is rotated inside the storage slot 201 by the movable shaft to support the ground, thus achieving the support and limitation of the template trolley body 1. Then, the control adjustment handwheel 5 is rotated, and the rotating shaft 402 is supported by the movable bearing 403 on the trolley bracket. The internal rotation of 2 causes the rotating shaft 402 to drive the inclined support mechanism 4 to swing on both sides of the trolley support 2, controlling the tilting rotation of the two inclined support mechanisms 4 on the outside of the trolley support 2 to support the surface with different tilt angles. By rotating the height adjustment screw 405 below the template 3 inside the threaded sleeve, the limiting collar at the end of the height adjustment screw 405 below the template 3 rotates. Therefore, the distance between the template 3 and the trolley support 2 can be controlled to form a herringbone shape that fits the top of the trench.
